                                NOTES DUE 2008
 
        GUARANTEED ON A SENIOR SUBORDINATED BASIS BY PIERCE LEAHY CORP.
 
 THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON NOVEMBER
                           10, 1998, UNLESS EXTENDED
                                --------------
  Pierce Leahy Command Company, a Nova Scotia unlimited liability company (the
"Issuer"), hereby offers to substitute (the "Exchange Offer"), upon the terms
and subject to the conditions set forth in this Prospectus and the
accompanying Letter of Transmittal (the "Letter of Transmittal"), up to
$135,000,000 in aggregate principal amount of the Issuer's new 8 1/8% Senior
Notes due 2008 (the "Exchange Notes"), for $135,000,000 in aggregate principal
amount of the Issuer's outstanding 8 1/8% Senior Notes due 2008 (the "Original
Notes"). The Original Notes and the Exchange Notes are sometimes referred to
herein collectively as the "Notes."
 
  The terms of the Exchange Notes are substantially identical in all respects
(including principal amount, interest rate and maturity) to the terms of the
Original Notes which they replace pursuant to this Exchange Offer, except that
(i) the Exchange Notes will be freely transferable by holders thereof (other
than as provided in the next paragraph) and issued free of any covenant
restricting transfer absent registration and (ii) holders of the Exchange
Notes will not be entitled to certain rights of holders of the Original Notes
under the Registration Agreement (as defined which rights will terminate upon
the consummation of the Exchange Offer. The Exchange Notes will evidence the
same debt as the Original Notes (which they replace) and will be entitled to
the benefits of an Indenture dated as of April 7, 1998 governing the Original
Notes and the Exchange Notes (the "Indenture"). For a complete description of
the terms of the Exchange Notes, see "Description of the Notes." There will be
no cash proceeds to the Issuer from the Exchange Offer.
 
  The Notes are redeemable at the option of the Issuer, in whole or in part,
at any time on or after May 15, 2003, at the redemption prices set forth
herein, plus accrued and unpaid interest to the date of redemption. In
addition, the Issuer, at its option, may redeem in the aggregate up to 35% of
the original principal amount of the Notes at any time and from time to time
prior to May 15, 2001 at 108 1/8% of the aggregate principal amount so
redeemed, plus accrued and unpaid interest thereon to the redemption date,
with the Net Proceeds (as defined herein) of one or more Public Equity
Offerings (as defined herein), provided that at least 65% of the aggregate
principal amount of the Notes originally issued remain outstanding immediately
after the occurrence of each such redemption. See "Description of the Notes--
Optional Redemption."
 
  The Notes will be senior unsecured obligations of the Issuer ranking pari
passu in right of payment with all existing and future senior unsecured
indebtedness of the Issuer and senior in right of payment to all existing and
future subordinated indebtedness of the Issuer. The Notes will be effectively
subordinated to all secured indebtedness of the Issuer to the extent of the
value of the assets securing such indebtedness. As of June 30, 1998, on a pro
forma basis after giving effect to the Recent Acquisitions (as defined
herein), there would have been approximately $2.4 million of secured
indebtedness outstanding of the Issuer to which holders of the Notes would be
effectively subordinated in right of payment. The Issuer is an indirect
subsidiary of Pierce Leahy Corp., a Pennsylvania corporation ("Pierce Leahy").
 
  The Notes will be guaranteed (the "Domestic Guarantees") on an unsecured
senior subordinated basis by Pierce Leahy, its two U.S. subsidiaries (Advanced
Box, Inc. and Monarch Box, Inc.) and by each future U.S. Restricted Subsidiary
(as defined herein) of Pierce Leahy (each, a "Domestic Guarantor").
Accordingly, the Domestic Guarantees will be subordinated in right of payment
to all existing and future Senior Indebtedness (as defined herein) of the
Domestic Guarantors and will rank pari passu in right of payment to all
existing and future senior subordinated indebtedness of the Domestic
Guarantors. As of June 30, 1998, on a pro forma basis after giving effect to
the Recent Acquisitions, the Domestic Guarantors would have had approximately
$116.9 million of Senior Indebtedness which would be senior in right of
payment to the Domestic Guarantees and $250 million of senior subordinated
indebtedness which would rank pari passu with the Domestic Guarantees.
 
  In addition, the Notes will be guaranteed (the "Canadian Guarantees") on a
senior unsecured basis by Archivex Limited, a Nova Scotia company ("Archivex")
which is a wholly-owned subsidiary of Pierce Leahy and which borrowed from the
Company a portion of the proceeds of the Offering, and by any future Canadian
subsidiaries of Pierce Leahy which are not prohibited by the laws of Canada or
any province thereof from acting as a guarantor of the Notes and which have
either assets or shareholders' equity in excess of $5,000 (each, a "Canadian
Guarantor"). As of June 30, 1998, on a pro forma basis after giving effect to
the Recent Acquisitions, the only indebtedness outstanding of Archivex would
be the amounts borrowed from the Issuer.
 
  Each current and future Domestic Guarantor and Canadian Guarantor will
guarantee the Notes on a full and unconditional basis, as described in detail
herein.
 
  Upon a Change of Control (as defined herein), each holder of the Notes will
be entitled to require the Issuer to purchase such holder's Notes at 101% of
the principal amount thereof, plus accrued and unpaid interest, if any, to the
purchase date. See "Description of the Notes--Change of Control Offer." There
can be no assurance that the Issuer will have sufficient funds or will be
contractually permitted by outstanding Senior Indebtedness of the Issuer or
Pierce Leahy to pay the required purchase price for all Notes tendered by
holders upon a Change of Control. If certain changes affecting Canadian
withholding taxes occur, the Notes may be redeemed by the Issuer at a
redemption price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest, if any, to the redemption date. See "Description of the
Notes--Redemption for Changes in Canadian Withholding Taxes."
 
  The Exchange Notes will bear interest from the most recent date to which
interest has been paid on the Original Notes, or if no interest has been paid
on the Original Notes, from April 7, 1998. Holders whose Original Notes are
accepted for exchange will not receive any payment in respect of interest on
such Original Notes otherwise payable on any interest payment date the record
date for which occurs on or after consummation of the Exchange Offer. See "The
Exchange Offer--Terms of the Exchange Offer."

 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
      EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION

  The Original Notes were sold (the "Offering") on April 7, 1998, in a
transaction not registered under the Securities Act of 1933, as amended (the
"Securities Act"), in reliance upon an exemption provided in the Securities Act.
Accordingly, the Original Notes may not be offered, resold or otherwise pledged,
hypothecated or transferred in the United States unless registered under the
Securities Act or unless an exemption from the registration requirements of the
Securities Act is available.  The Exchange Notes are being offered to satisfy
the obligations of the Issuer under the Registration Agreement (as defined
herein) relating to the Original Notes.  See "The Exchange Offer-Purposes and
Effects of the Exchange Offer."  Each holder receiving Exchange Notes, other
than a broker-dealer, will represent that the holder is not engaging in or
intending to engage in a distribution of such Exchange Notes.  Exchange Notes
issued pursuant to the Exchange Offer in substitution for the Original Notes may
be offered for resale, resold or otherwise transferred by the holders thereof
(other than any holder that is an affiliate of the Issuer within the meaning of
Rule 405 under the Securities Act), without compliance with the registration and
prospectus delivery requirements of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such holders' business and
such holders have no arrangement or understanding with any person to participate
in the distribution of such Exchange Notes.  Each broker-dealer that receives
Exchange Notes for its own account pursuant to the Exchange Offer must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes.  The Letter of Transmittal states that by acknowledging and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.  See "The Exchange
Offer-Purposes and Effects of the Exchange Offer" and "Plan of Distribution."
Broker-dealers may use this Prospectus, as amended or supplemented, in
connection with resales of the Exchange Notes received in exchange for the
Original Notes where such Original Notes were acquired by such broker-dealer as
a result of market making activities or other such trading.

  The Exchange Offer is not conditioned on any minimum aggregate principal
amount of Original Notes being tendered for substitution.  The Issuer will
accept for substitution any and all validly tendered Original Notes not
withdrawn prior to 5:00 p.m., New York City time, on November 10, 1998 unless
extended by the Issuer, in its sole discretion (the "Expiration Date").  Tenders
of Original Notes may be withdrawn at any time prior to the Expiration Date.
The Exchange Offer is subject to certain customary conditions.  See "The
Exchange Offer-Conditions." Original Notes may be tendered only in integral
multiples of $1,000.  The Issuer will pay all expenses incident to the Exchange
Offer.

  The Notes constitute securities for which there is no established trading
market. Any Original Notes not tendered and accepted in the Exchange Offer will
remain outstanding. The Issuer does not currently intend to list the Exchange
Notes on any securities exchange. To the extent that any Original Notes are
tendered and accepted in the Exchange Offer, a holder's ability to sell
untendered Original Notes could be adversely affected. No assurances can be
given as to the liquidity of the trading market for either the Original Notes or
the Exchange Notes.

                          THE ISSUER AND THE COMPANY

  Pierce Leahy Command Company, a Nova Scotia unlimited liability company
("Command" or the "Issuer"), is the issuer of the Notes and is an indirect
subsidiary of Pierce Leahy, which is a guarantor of the Notes on an unsecured
senior subordinated basis.  The Issuer operates 26 records management facilities
in the eight largest markets in Canada.  In 1997, certain members of the Pierce
family entered into a voting trust agreement pursuant to which Leo W. Pierce,
Sr. and J. Peter Pierce, as voting trustees, are eligible to direct the voting
with respect to the shares subject to the voting trust agreement.  Currently,
approximately 51% of the outstanding shares of the Company's Common Stock are
subject to the voting trust agreement.  Consequently, the voting trustees are
able to determine the outcome of corporate actions requiring shareholder
approval and otherwise control the business affairs of the Company.  See
"Principal Shareholders of Pierce Leahy-Voting Trust Agreement."

  The Company is the largest hard copy records management company in North
America, as measured by its 78 million cubic feet of records currently under
management.  The Company operates a total of 222 records management facilities
of which 192 are in the United States, serving 69 markets, including 23 of the
25 largest U.S. markets.  In addition, the Company operates 30 records
management facilities in Canada's nine largest markets, including 26 facilities
operated by the Issuer and four facilities operated by Archivex.

  The Company is a full-service provider of records management and related
services, enabling customers to outsource their data and records management
functions.  The Company offers storage for all major media, including paper
(which has typically accounted for approximately 95% of the Company's storage
revenues), computer tapes, optical discs, microfilm, video tapes and X-rays.  In
addition, the Company provides next day or same day records retrieval and
delivery, allowing customers prompt access to all stored material.  The Company
also offers other data management services, including customer records
management programs, imaging services and records management consulting
services.

  The Company believes it is the most technologically advanced records
management company in the industry by virtue of its Pierce Leahy User
Solution/(R)/ (PLUS/(R)/) computer system.  The PLUS/(R)/ system fully
integrates the Company's records management, data retrieval and billing
functions on a centralized basis through the use of proprietary, real-time
software.  The PLUS/(R)/ system assists the Company in efficiently managing
records in multiple locations for national and local customers, rapidly
integrating acquisitions of records management companies and maintaining a low-
cost operating structure.  The Company serves a diversified group of over 40,000
customer accounts in a variety of industries such as financial services,
manufacturing, transportation, healthcare and law.  The Company's storage and
related services are typically provided pursuant to contracts that include
recurring monthly storage fees, which continue until such records are
permanently removed (for which the Company charges a fee), and additional
charges for services such as retrieval on a per unit basis.

  From 1993 to 1997, the Company's revenues grew at an average annual rate of
25.8%. The Company attributes this growth to the expansion of its business with
new and existing customers, which has been primarily driven by the trend towards
outsourcing of records management functions by companies and the ongoing
consolidation of the fragmented

                                      -2-
<PAGE>
 
records management industry. The Company successfully acquired and integrated 39
companies from 1993 to 1997. In addition, the Company has acquired 16 companies
since the beginning of 1998.

  The Company's growth strategy is to expand its business in new and existing
markets through (i) targeting new customers, (ii) growing with existing
customers and (iii) continuing its acquisition program.  The Company has adopted
the following approaches to pursue its growth objectives:

   . TARGETING NEW CUSTOMERS.  The Company has a dual sales strategy focused on
     both larger, typically multi-location accounts and smaller accounts, with a
     dedicated sales force for each.  The Company's sales and marketing force
     has increased from approximately 70 persons at the end of 1996 to
     approximately 130 persons currently.  For large regional and national
     accounts, the Company believes its national presence, sophisticated systems
     and low-cost operating structure provide a competitive advantage.  These
     organizations are increasingly outsourcing such noncore activities, which
     enables their management to focus on their core business and to reduce
     space requirements and records management costs.  For smaller accounts, the
     Company combines the cost benefits of its centralized systems with quality
     local service.  From 1993 to 1997, the average annual growth rate of cubic
     feet of storage from new customers was approximately 9%.

   . GROWING WITH EXISTING CUSTOMERS.  The Company services its existing
     customers through both a centralized customer service organization and
     local client service representatives.  Existing customers typically
     generate additional records annually which are stored with the Company.
     From 1993 to 1997, the average annual growth rate of cubic feet of storage
     from existing customers was approximately 6%.

   . CONTINUING ACQUISITION PROGRAM.  The Company believes that the records
     management industry is highly fragmented and offers substantial opportunity
     for consolidation.  The Company targets potential acquisitions both in the
     markets it already services and in new markets which it is not yet
     servicing.  From 1993 to 1997, the Company successfully completed and
     integrated 39 acquisitions, totalling approximately 22.3 million cubic feet
     of records at the time of acquisition.  Since the beginning of 1998, the
     Company has acquired 16 records management companies, adding an aggregate
     of 13.2 million cubic feet of records (an increase of approximately 22%
     from December 31, 1997) at the time of acquisition, including the
     acquisition of Archivex Inc. (the "Archivex Acquisition") and the
     acquisition of Kestrel Holdings, Inc. (the "Kestrel Acquisition").  As a
     result of its centralized organizational structure and the PLUS/(R)/
     system, the Company has been able to rapidly achieve significant economies
     of scale in its acquisitions.  From 1993 to 1997, the average annual growth
     rate of cubic feet of storage from acquisitions was approximately 15%.  See
     "Business--Acquisition and Growth Strategy."  The Company has traditionally
     financed its acquisitions with debt.  See "Risk Factors -- Potential
     Inability to Repay Debt."

  The Company's growth strategy is supported by an operating strategy which
emphasizes providing premium standardized services while maintaining a low-cost
operating structure.  Both strategies apply to the entire North American market
(United States and Canada).  The Company expects to continue its growth and
enhance its position by implementing its strategy based on the following
elements:

   . USING SOPHISTICATED CENTRALIZED SYSTEMS TO PROVIDE HIGH QUALITY SERVICE.
     In tandem with the Company's centralized customer service organization and
     local field support personnel, the Company utilizes its PLUS/(R)/ system to
     provide a high and consistent level of service (24 hours a day, seven days
     a week) to its customers on a national and local basis, including providing
     its customers with real-time access to the database.  Although PLUS/(R)/ is
     centralized, the system permits local management flexibility through a
     variety of pre-programmed options to customize the system and enhance its
     utility to different types of customers.


   . MAINTAINING ITS POSITION AS A LOW-COST PROVIDER THROUGH ECONOMIES OF SCALE.
     The Company strives to remain a low-cost operator through achieving
     economies of scale in labor, real estate, transportation, computer systems
     and administrative expenses.  The PLUS/(R)/ system allows the Company to
     enhance the efficiency of its facilities while reducing fixed and operating
     costs.  This system eliminates the need to designate permanent 

                                      -3-
<PAGE>
 
     locations for an individual customer's records within a facility by using
     sophisticated bar-coding technology which enables records to be stored
     wherever space is available and to be positioned within the Company's
     facilities based on retrieval frequency, thereby reducing labor costs.
     PLUS/(R)/ is also valuable in helping to achieve cost savings in
     acquisitions.

                        THE RECORDS MANAGEMENT INDUSTRY

  According to a 1994 study by the Association of Commercial Record Centers (the
"ACRC"), an industry trade group with over 500 members, approximately 2,600
companies offer records storage and related services in North America.  The
Company believes that only 25% of the potential market outsources its records
management functions and that approximately 75% is still "unvended," or
internally managed.  The Company estimates that the North American vended
records management industry generates annual revenues in excess of $1.0 billion.
Management believes that the industry is highly fragmented, with most industry
participants operating on a regional or local basis.

  Saved documents, or records, generally fall into two categories: active and
inactive.  Active records refer to information that is frequently referenced and
usually stored on-site by the originator.  Inactive records are not needed for
frequent access, but must be retained for future reference, legal requirements
or regulatory compliance.  Inactive records, which the Company estimates
comprise approximately 80% of all records, are the principal focus of the
records management industry.

  The Company believes that the records management industry is characterized by
the following trends:

   . INDUSTRY CONSOLIDATION.  The records management industry is undergoing a
     period of consolidation as larger, better capitalized industry participants
     acquire smaller regional or local participants.  Management believes that
     consolidation is primarily driven by the needs of large customers for fully
     integrated coverage and the ability to realize economies of scale,
     especially with respect to labor, real estate, transportation, computer
     systems and administrative expenses.  Industry consolidation also provides
     private owners of smaller records management companies the ability to
     obtain liquidity.

   . MOVEMENT TOWARDS OUTSOURCING.  Outsourcing of internal records management
     functions represents the largest single source of new business for records
     management companies.  The Company believes that as more organizations
     become aware of the advantages of professional records management, such as
     net cost reductions and enhanced levels of service, the records management
     industry will continue to gain a growing portion of the unvended segment.
     The Company also believes that the establishment of national providers with
     well-known brand names will help to accelerate this trend.

   . INCREASING PRODUCTION OF PAPER.  Increasingly widespread technologies such
     as facsimiles, copiers, personal computers, laser printers and advanced
     software packages have enabled organizations to create, copy and distribute
     documents more easily and broadly.  In spite of new "paperless"
     technologies (including the Internet and "e-mail"), information remains
     predominantly paper based.  Additionally, the cost of storing records on
     paper is currently less expensive than the cost of converting paper records
     to, and storing on, other media (e.g., computer media, imaging, microfilm,
     CD-Rom and optical disc).

   . EXPANDED RECORD KEEPING NEEDS.  While technology has augmented the growth
     of paper generation, several external forces and concerns have played an
     important role in organizations' decisions to store and retain access to
     records. For example, the continued growth of regulatory requirements and
     the proliferation of litigation has resulted in increased volumes and
     lengthened holding periods of documents. Retained records are also
     remaining in storage for extended periods of time because the process of
     determining which records to destroy is time consuming and often more
     costly in the short-term than continued storage.

                           THE ARCHIVEX ACQUISITION

                                      -4-
<PAGE>
 
  Concurrently with the Offering, the Company acquired substantially all of the
assets of Archivex Inc., a Canadian corporation, with a portion of the proceeds
of the Offering.  Archivex Inc. had operations in six Canadian cities, including
three markets in which the Issuer previously operated (Calgary, Montreal and
Toronto) and three new markets in which Command did not previously have a
presence (Edmonton, Quebec City and Winnipeg).  A newly formed wholly-owned
subsidiary of Pierce Leahy, Archivex, purchased and operates the assets of
Archivex Inc. in Montreal.  The Issuer purchased the remaining assets of
Archivex Inc.  The aggregate cash consideration for the Archivex Acquisition,
which represented a significant expansion in the Canadian market for the
Company, was approximately $63.0 million.  Included in the Archivex Acquisition

                                        Securities Act and (ii) holders of
                                        the Exchange Notes will not be
                                        entitled to certain rights of holders

                                        of the Exchange Offer.  See "The
                                        Exchange Offer."
 
                                        Based on an interpretation by the staff
                                        of the Securities and Exchange

                                        parties, the Issuer believes that the
                                        Exchange Notes issued pursuant to the
                                        Exchange Offer in substitution for

                                        resale, resold and otherwise transferred
                                        by a holder thereof (other than (i) a

                                        Exchange Notes directly from the Issuer
                                        to resell pursuant to Rule 144A under

                                        without compliance with the registration
                                        and prospectus delivery provisions of
                                        the Securities Act, provided that the
                                        holder is acquiring the Exchange Notes
                                        in the ordinary course of its business
                                        and is not participating, and had no

                                        replacement will be deemed to have
                                        waived the right to receive any
                                        interest accrued on the Original

                                        unsecured obligations of the Issuer,
                                        ranking pari passu in right of payment
                                        with all existing and future senior
                                        indebtedness of the Issuer and senior in
                                        right of payment to all existing and
                                        future subordinated indebtedness of the
                                        Issuer. The Notes will be effectively
                                        subordinated to all secured indebtedness
                                        of the Issuer to the extent of the value
                                        of the assets securing such
                                        indebtedness. As of June 30, 1998, on a
                                        pro forma basis after giving effect to
                                        the Recent Acquisitions (which, as
                                        defined herein, includes the Kestrel
                                        Acquisition), the Issuer would have
                                        approximately $.7 million of senior
                                        indebtedness ranking pari passu which
                                        consists of trade payables. In addition
                                        as of such date, on a pro forma basis
                                        the Issuer would have had approximately
                                        $2.4 million of secured indebtedness
                                        outstanding to which holders of the
                                        Notes would have been effectively
                                        subordinated in right of payment. The
                                        Indenture permits the Issuer to incur
                                        additional indebtedness, including
                                        secured senior indebtedness, subject to
                                        certain limitations, to which the Notes
                                        will be effectively subordinated to the
                                        extent of the value of the assets
                                        securing such indebtedness.

                                        "Domestic Guarantees"), on an
                                        unsecured senior subordinated basis,
                                        by Pierce Leahy and by each current
                                        and future U.S. Restricted Subsidiary

                                        The Domestic Guarantees will be
                                        subordinated in right of payment to
                                        all existing and future Senior
                                        Indebtedness (as defined herein) of

                                        Acquisitions, the Domestic Guarantors
                                        would have had approximately $116.9
                                        million of Senior Indebtedness which
                                        would be

                                        on an unsecured senior basis, by
                                        Archivex and by future Canadian

                                        will be effectively subordinated to all
                                        secured obligations of the respective

                                        including the Credit Facility. As of

                                        indebtedness of Archivex, the only
                                        current Canadian Guarantor, would have
                                        been the amounts borrowed by it from the
                                        Issuer. Each current and future Domestic

                                        will guarantee the Notes on a full and

                                        indebtedness, subject to certain
                                        limitations, to which the Domestic
                                        Guarantees will be subordinated and,
                                        effectively subordinated to the extent
                                        of the value of assets securing any such

                                        that at least 65% of the original

                                        withholding taxes, the Notes will be

                                        (if any) to but excluding the
                                        redemption date.  See "Description of

                                        by the interpretation or administration
                                        thereof by the relevant government

                                        as may be necessary so that the net
                                        amount received by holders of the Notes

                                        amount that would have been received in
                                        the absence of such withholding or

     SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA OF PIERCE LEAHY CORP.


The following summary historical and pro forma financial data of Pierce Leahy
Corp., insofar as it relates to each of the five years in the period ended
December 31, 1997, has been derived from the Company's audited consolidated
financial statements, including the consolidated balance sheets at December 31,
1996 and 1997, and the related consolidated statements of operations for each of
the three years in the period ended December 31, 1997 and the notes thereto
incorporated by reference into this Prospectus.  The summary historical and pro
forma consolidated statements of operations and balance sheet data as of and for
the six months ended June 30, 1998 and summary historical statement of
operations data for the six months ended June 30, 1997 have been derived from
unaudited consolidated financial statements incorporated by reference into this
Prospectus which, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results for the unaudited interim periods.  Results for the
six months ended June 30, 1998 are not necessarily indicative of results that
may be expected for the entire year.

The following summary pro forma statement of operations and other data give
effect to, among other things, acquisitions completed in 1997, the 1998
Acquisitions (all such 1997 acquisitions and the 1998 Acquisitions, the "1997
and 1998 Acquisitions") and the impact of the Offering, as if each of these
items had occurred on January 1, 1997.  The pro forma balance sheet gives effect
to the 1998 acquisitions which closed after June 30, 1998 (the "Recent
Acquisitions") as if the Recent Acquisitions had occurred on June 30, 1998.  In
1997, the Company recorded a deferred income tax provision of $6,600 (in
thousands) in connection with the termination of the Company's status as a
Subchapter S corporation for the tax effect of differences in the basis of
assets and liabilities for financial reporting and income tax purposes.  This
one-time deferred income tax provision has been eliminated in the Pro Forma
Condensed Consolidated Statement of Operations.  Also not reflected in the Pro
Forma Condensed Consolidated Statement of Operations is the extraordinary charge
of $6,036 (in thousands) for the early extinguishment of a portion of the 1996
Notes that occurred in August 1997.

The pro forma items and certain management assumptions and adjustments are
described in the accompanying notes hereto.  This pro forma information is not
necessarily indicative of the results that would have occurred had the 1997 and
1998 Acquisitions and the Offering been completed on the dates indicated or of
the Company's actual or future results or financial position.  The summary
historical and pro forma consolidated statements of operations, other data and
balance sheets should be read in conjunction with the information contained in
the Company's Consolidated Financial Statements and the notes thereto
incorporated by reference into this Prospectus and "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Selected Historical
and Pro Forma Consolidated Statements of Operations, Other Data and Balance
Sheets of Pierce Leahy Corp." and "Pro Forma Financial Data of Pierce Leahy
Corp." included elsewhere in this Prospectus.

NOTES TO SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA OF PIERCE LEAHY CORP.

(a)  Gives effect to (i) the 1997 and the 1998 Acquisitions and (ii) the impact
     of the Offering, as if each of these items had occurred on January 1, 1997.
     See "Pro Forma Financial Data of Pierce Leahy Corp." and Note 2 of the
     Notes to Consolidated Financial Statements incorporated by reference
     herein.  In 1997, the Company recorded a deferred income tax provision of
     $6,600 in connection with the termination of the Company's status as a
     Subchapter S corporation for the tax effect of differences in the basis of
     assets and liabilities for financial reporting and income tax purposes.
     This one-time deferred income tax provision has been eliminated in the
     December 31, 1997 Pro Forma Condensed Consolidated Statement of Operations.
     Also not reflected in the December 31, 1997 Pro Forma Condensed
     Consolidated Statement of Operations is the extraordinary charge of $6,036
     for the early extinguishment of a portion of the 1996 Notes that occurred
     in August 1997.  See Note (f) below.

(b)  Upon consummation of Pierce Leahy's 1997 initial public offering, options
     granted during 1997 became fully vested and exercisable as provided for
     under the stock option plan.  The Company recorded a non-recurring, non-
     cash compensation charge of $1,752 relating to those options, representing
     the difference between the exercise price and the deemed value for
     accounting purposes.

(c)  Represents aggregate payments made to eight Pierce family members.

(d)  Represents non-recurring charge in 1996 of $2,764 paid to a related party
     partnership to assume the partnership's position in certain leases with
     third parties and of $490 for the establishment of an annual pension for
     Leo W. Pierce, Sr. and his spouse.

(e)  Until July 1, 1997, the Company was taxed as a Subchapter S corporation.
     Such status was terminated in connection with Pierce Leahy's 1997 initial
     public offering. See "Management's Discussion and Analysis of Financial
     Condition and Results of Operations" and Note 2 of Notes to Consolidated
     Financial Statements incorporated by reference herein.

(f)  Represents loss on early extinguishment of debt due to refinancings in
     1993, 1994, 1995, 1996 and 1997. Amounts include the write-off of
     unamortized deferred financing costs and discount, along with prepayment
     penalties and other costs. A charge for the early extinguishment of a
     portion of the 1996 Notes of $6,036 occurred in August 1997. Such charge
     has been eliminated in the Pro Forma Condensed Consolidated Statement of
     Operations. See  "Management's Discussion and Analysis of Financial
     Condition and Results of Operations."

(g)  Excluding $15,381 and $2,628 of operating expenses included in the pro 
     forma statements of operations for 1997 and for the six months ended June
     30, 1998, respectively, specifically identified by management that would
     not have been incurred had the 1997 and 1998 Acquisitions occurred as of
     January 1, 1997 and had such cost savings been fully implemented as of such
     date, and excluding the special compensation charge incurred in 1997, pro
     forma net income (loss) and basic and diluted net income (loss) per share
     would have been $161 and $0.01, respectively, in 1997 and ($4,847) and
     ($0.28) for the six months ended June 30, 1998, respectively.

(h)  The earnings for the year ended December 31, 1997 and for the six months
     ended June 30, 1997 and 1998 were inadequate to cover fixed charges by
     $1,737, $39  and $4,529, respectively.

(i)  "EBITDA" is defined as net income (loss) before interest expense, taxes,
     depreciation and amortization, consulting payments to related parties, non-
     recurring charges with related parties, foreign currency exchange, special
     compensation charge and extraordinary charge. EBITDA is not a measure of
     performance under Generally Accepted Accounting Principles ("GAAP").
     Moreover, the use of EBITDA by the Company may not be comparable to
     similarly titled measures as reported by other companies.  While EBITDA
     should not be considered in isolation or as a substitute for net income,
     cash flows from operating activities and other income or cash flow
     statement data prepared in accordance with GAAP, or as a measure of
     profitability or liquidity, management understands that EBITDA is
     customarily used as a criteria in evaluating records management companies.
     However, substantially all of the Company's financing agreements, including
     the Notes and the 1996 Notes and the 1997 Notes (each as hereinafter
     defined), contain covenants in which EBITDA is used as a measure of
     financial performance. See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations" for a discussion of other
     measures of performance determined in accordance with GAAP and the
     Company's sources and applications of cash flows.

(j)  EBITDA, as adjusted is defined as EBITDA plus $15,381 and $2,628 of
     operating expenses included in the pro forma statements of operations for
     1997 and for the six months ended June 30, 1998, respectively, specifically
     identified by management that would not have been incurred had the 1997 and
     1998 Acquisitions occurred as of January 1, 1997 and such cost savings been
     fully implemented as of such date. See Note (b) of Notes to Pro Forma
     Condensed Consolidated Statements of Operations. Management expects to
     realize additional cost savings beyond the $15,381 and $2,628 specifically
     identified.

(k)  Capital expenditures for 1997 are comprised of $14.9 million for new
     shelving, $3.5 million for leasehold and building improvements, $10.6
     million for new facility purchases and related improvements, $3.7 million
     for data processing and $2.7 million for the purchase of transportation,
     warehouse and office equipment.

(l)  The pro forma cubic feet of storage as of June 30, 1998 includes cubic feet
     of storage from the Recent Acquisitions at the time of their respective
     acquisitions.

(m)  Gives effect to the Recent Acquisitions as if such acquisitions had
     occurred on June 30, 1998.

                                 RISK FACTORS

  Prospective purchasers of the Exchange Notes should consider carefully the
following risk factors, in addition to the other information set forth in this
Prospectus, before making an investment in the Notes.

HIGH LEVEL OF INDEBTEDNESS AND LEVERAGE

  As of June 30, 1998, on a pro forma basis after giving effect to the Recent
Acquisitions, the Issuer's and the Company's indebtedness would have been
approximately $136.9 million (excluding trade payables) and $503.8 million
(excluding trade payables), respectively.  In addition, on a pro forma basis
after giving effect to the Offering, the application of the net proceeds
therefrom, and the 1998 Acquisitions, the Issuer's 1997 EBITDA would have been
$7.4 million.  The pro forma 1997 EBITDA of the Issuer, exclusive of any
Guarantors, would not have been sufficient to cover the interest payments on the
Notes.  This level of indebtedness will have important consequences to holders
of the Notes, including: (i) the Issuer would have had to, and may in the future
have to, borrow under the Credit Facility or from another source, including
possibly from Pierce Leahy, in order to make interest payments on the Notes;
(ii) a substantial part of the Company's anticipated cash flow from operations
will be required for the payment of principal and interest; (iii) the Issuer's
and the Company's ability to obtain additional financing in the future may be
limited; (iv) the Issuer's and the Company's leveraged position and covenants
contained in the Notes, the 1996 Notes, the 1997 Notes (each as defined herein)
and the Credit Facility (or any replacement thereof) could limit its ability to
expand and make capital improvements and acquisitions; and (v) the Company's and
the Issuer's level of indebtedness could make it more vulnerable to economic
downturns, limit its ability to withstand competitive pressures, and limit its
flexibility in reacting to changes in its industry and economic conditions
generally.  See "Description of Certain Indebtedness."

POTENTIAL INABILITY TO REPAY DEBT

  The Issuer's and the Company's ability to meet their respective debt service
obligations will be dependent upon their future operating performance (including
the performance of any acquired businesses), debt levels and financial results
which, in turn, will be subject to general economic conditions and to financial,
business and other factors affecting the operations of the Issuer and the
Company, many of which are beyond their control.  For the year ended December
31, 1997 and the six months ended June 30, 1998, on a pro forma basis after
giving effect to the Offering, the application of the net proceeds therefrom and
the 1998 Acquisitions, the Company's cash interest expense would have been $41.2
million and $20.6 million, respectively.  Although management believes that the
Issuer's and the Company's cash flow from operations and available borrowings
under the Credit Facility will be sufficient to meet their anticipated
requirements for capital expenditures, working capital and future debt service
requirements, there can be no assurance that the Issuer or the Company will
generate cash flows at levels sufficient to meet these requirements.  To the
extent that the Issuer's or the Company's existing resources and future earnings
are insufficient to fund their respective activities or to repay indebtedness,
the Company may need to raise additional funds through public or private
financings.  There can be no assurance that such additional financing would be
available on acceptable terms or at all.

UNSECURED OBLIGATIONS; EFFECTIVE SUBORDINATION OF NOTES; GUARANTEES SUBORDINATED

  The Notes will be senior unsecured obligations of the Issuer ranking pari
passu in right of payment with all existing and future senior unsecured
indebtedness of the Issuer and senior in right of payment to all existing and
future subordinated indebtedness of the Issuer. The Notes are not secured by any
of the assets of the Issuer. Accordingly, holders of any secured indebtedness of
the Issuer will have claims that are prior to the claims of holders of the Notes
with respect to the assets securing such secured indebtedness. As of June 30,
1998, on a pro forma basis after giving effect to the Recent Acquisitions, the
Issuer would have had $.7 million of indebtedness ranked pari passu with the
Notes, which consists of trade payables. In addition, as of such date, on a pro
forma basis after giving effect to the Recent Acquisitions, the Issuer would
have had $2.4 million of secured indebtedness to which holders of the Notes
would be effectively subordinated in right of payment. The Credit Facility is
secured by substantially all of the assets of the Company. Accordingly, the
Notes will be effectively subordinated to any amounts borrowed by the Issuer
under the Credit Facility to the extent of the assets securing the Credit
Facility.

                                      -16-
<PAGE>
 
  The Notes will be guaranteed on an unsecured senior subordinated basis by each
Domestic Guarantor and on a senior unsecured basis by each Canadian Guarantor.
As of June 30, 1998, on a pro forma basis after giving effect to the Recent
Acquisitions, the Domestic Guarantors would have had $116.9 million outstanding
of senior indebtedness which would be senior in right of payment to the Domestic
Guarantees and $250 million of senior subordinated indebtedness which would rank
pari passu with the Domestic Guarantees.  As of June 30, 1998, Archivex,
currently the only Canadian Guarantor, had no outstanding indebtedness except
for amounts borrowed from the Issuer.  The Indenture permits the Issuer and the
Guarantors to incur additional indebtedness, including secured senior
indebtedness.

RISKS ASSOCIATED WITH ACQUISITIONS

  One of the Company's strategies is to acquire records management businesses
that will complement its existing operations or provide it with an entree into
areas it does not presently serve.  There can be no assurance that the Company
will be able to acquire or profitably manage additional acquisitions or
successfully integrate them into the Company.  Furthermore, certain risks are
inherent in the Company's acquisition strategy, such as increasing leverage and
debt service requirements, diversion of management time and attention, and
combining disparate company cultures and facilities, which could adversely
affect the Company's operating results.  The success of any acquisition will
depend in part on the Company's ability to integrate effectively the acquired
records management business into the Company.  See "Business--Acquisition and
Growth Strategy."

  In this regard, the Company's success will be dependent, in part, upon its
ability to effectively integrate the Archivex Acquisition and the Kestrel
Acquisition, which represent two of the Company's largest acquisitions to date,
with the Company's operations.  The integration and consolidation of the
Archivex Acquisition and the Kestrel Acquisition entail certain risks and will
require substantial management time and other resources.  While the Company
believes that it has sufficient management and other resources to accomplish the
integration of the Archivex Acquisition and the Kestrel Acquisition, there can
be no assurance in this regard or that the Company will not experience
difficulties with customers, suppliers, employees or others.  In addition, there
can be no assurance that the Company will be able to achieve expected cost
savings from any such acquisitions.

  The size, timing and integration of possible future acquisitions may cause
substantial fluctuations in operating results from quarter to quarter.  As a
result, operating results for any quarter may not be indicative of results that
may be achieved for any subsequent quarter or for a full fiscal year.  Further,
there can be no assurance that acquisitions will not have an adverse effect on
the Company's operating results, particularly in quarters immediately following
the consummation of such transactions, while the operations of the acquired
businesses are being integrated into the Company's operations.  Once integrated,
acquisitions may not achieve levels of net sales or profitability comparable to
those achieved by the Company's existing operations, or otherwise perform as
expected.  In addition, earnings may be adversely affected by transaction-
related expenses in the quarter in which an acquisition is consummated.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

RESTRICTIVE DEBT COVENANTS

  The Credit Facility contains a number of covenants that, among other things,
limit the Company's ability to incur additional indebtedness, pay dividends,
prepay subordinated indebtedness, dispose of certain assets, create liens, make
capital expenditures, make certain investments or acquisitions and otherwise
restrict corporate activities. The Credit Facility also requires the Company to
comply with certain financial ratios and tests, under which the Company will be
required to achieve certain financial and operating results. The ability of the
Company to comply with such provisions may be affected by events beyond its
control. A breach of any of these covenants would result in a default under the
Credit Facility. In the event of any such default, depending on the actions
taken by the lenders under the Credit Facility, the Domestic Guarantors could be
prohibited from making any payments on the Domestic Guarantees. In addition,
such lenders could elect to declare all amounts borrowed under the Credit
Facility, together with accrued interest, to be due and payable. As a result of
the security afforded the Credit Facility and its priority with respect to the
Domestic Guarantees, there can be no assurance that the Issuer or the Guarantors
would have sufficient assets to pay indebtedness then outstanding under the
Credit Facility, the Notes and other indebtedness ranking pari passu with the
Notes or the

                                      -17-
<PAGE>
 
Domestic Guarantees. Any refinancing of the Credit Facility is likely to contain
similar restrictive covenants. See "Description of Certain Indebtedness--The
Credit Facility."

COMPETITION

  The Company faces competition from numerous competitors in all geographic
areas in which it operates.  The Company believes that competition for customers
is based on price, reputation for reliability, and quality and scope of service
and technology.  As a result of this competition, the records management
industry has for the past several years experienced downward pricing pressures.
Should a further downward trend in pricing occur or continue for an extended
period of time, it could have a material adverse effect on the Company's results
of operations.  The Company also competes for acquisition candidates.  Some of
the Company's competitors possess greater financial and other resources than the
Company.  If any such competitor were to devote additional resources to the
records storage business and/or such acquisition candidates or to focus its
strategy on the Company's areas of operation, the Company's results of
operations could be adversely affected.

  The Company also faces competition from the internal document handling
capability of its current and potential customers.  There can be no assurance
that these organizations will outsource more of their document management needs
or that they will not bring in-house some or all of the functions they currently
outsource.  See "Business--The Records Management Industry" and "Business--
Competition."

ALTERNATIVE TECHNOLOGIES

  The substantial majority of the Company's revenues have been derived from the
storage of paper documents and from related services.  Such storage requires
significant physical space.  Alternative technologies for generating, capturing,
managing, transmitting and storing information have been developed, many of
which require significantly less space than paper.  Such technologies currently
include computer media, imaging, microfilming, audio/video tape, film, CD-Rom
and optical disc.  None of these technologies has replaced paper as the
principal means for storing business type records.  However, there can be no
assurance that one or more non-paper-based technologies (whether now existing or
developed in the future) may not in the future reduce or supplant the use of
paper as a preferred medium, which could in turn adversely affect the Company's
business.

RISKS RELATING TO INTERNATIONAL OPERATIONS

  A portion of the Company's operations, and all of the Issuer's operations, are
conducted in Canada.  As a result of their international operations, the Company
and the Issuer are subject to risks associated with operating in foreign
countries, including, among others, devaluations and fluctuations in currency
exchange rates, imposition of limitations on conversions of foreign currencies
into dollars or remittance of dividends and other payments by foreign
subsidiaries, and imposition or increase of withholding and other taxes on
remittances and other payments by foreign subsidiaries.  There can be no
assurance that such risks will not have a material adverse effect on the
Company's or the Issuer's business and results of operations.

CHANGE OF CONTROL

  In the event of a Change of Control of Pierce Leahy, the Issuer will be
required to offer to repurchase all of the outstanding Notes at 101% of the
principal amount thereof plus any accrued and unpaid interest thereon to the
date of the purchase. The 1996 Notes and the 1997 Notes have a similar provision
requiring Pierce Leahy to offer to repurchase such Notes. A Change of Control
under the Indenture will also result in a default under the Credit Facility. The
exercise by the holders of the Notes, the 1996 Notes or the 1997 Notes of their
right to require the Issuer or Pierce Leahy to repurchase the Notes, the 1996
Notes or the 1997 Notes, as applicable, upon a Change of Control could also
cause a default under other indebtedness of the Company and the Issuer, even if
the Change of Control itself does not, because of the financial effect of such
repurchase on the Company or the Issuer. The Issuer's ability to pay cash to the
holders of the Notes upon a repurchase may be limited by the Issuer's and the
Company's then existing financial resources.

                                      -18-
<PAGE>
 
There can be no assurance that in the event of a Change of Control, the Issuer
and the Company will have, or will have access to, sufficient funds or will be
contractually permitted under the terms of outstanding indebtedness to pay the
required purchase price for all the Notes, the 1996 Notes and the 1997 Notes
tendered by their respective holders upon a Change of Control. See "Description
of the Notes" and "Description of Certain Indebtedness--The 1996 Notes and the
1997 Notes" and "--The Credit Facility."

DEPENDENCE ON KEY PERSONNEL

  The Company's success depends, in part, upon the efforts, abilities and
expertise of its executive officers and other key employees, including in
particular J. Peter Pierce, Pierce Leahy's President and Chief Executive
Officer.  The Company has no employment contracts with any of its executive
officers.  There can be no assurance that the Company will be able to retain
such officers, the loss of any of whom could have a material adverse effect upon
the Company and the Issuer.  See "Management."

U.S. FRAUDULENT CONVEYANCE AND PREFERENTIAL TRANSFER LAWS

  Various fraudulent conveyance laws have been enacted for the protection of
creditors and may be utilized by a court to subordinate or avoid the Notes or
any Guarantee in favor of other existing or future creditors of the Issuer or a
Guarantor.

  In the United States, if the court in a lawsuit brought by an unpaid creditor
or representative of creditors, such as a trustee in bankruptcy of the Issuer or
of a Domestic Guarantor, as the case may be, were to find under relevant U.S.
federal or state fraudulent conveyance statutes that the Issuer or such Domestic
Guarantor, as the case may be, (x) intended to hinder, delay or defraud any
existing or future creditor or contemplated insolvency with a design to prefer
one or more creditors to the exclusion in whole or in part of others or (y) did
not receive fair consideration or reasonably equivalent value for incurring the
indebtedness represented by the Notes or the Domestic Guarantees and that, at
the time of such incurrence, the Issuer or such Domestic Guarantor (i) was
insolvent, (ii) was rendered insolvent by reason of such incurrence, (iii) was
engaged or was about to engage in a business or transaction for which the assets
remaining with the Issuer or such Domestic Guarantor constituted unreasonably
small capital to carry on its business or (iv) intended to incur, or believed
that it would incur, debts beyond its ability to pay such debts as they matured,
such court, subject to applicable statutes of limitation, could avoid the
Issuer's obligations under the Notes or such Domestic Guarantor's obligations
under the Domestic Guarantee, subordinate the Notes or such Domestic Guarantee
to other indebtedness of the Issuer or such Domestic Guarantor or take other
action detrimental to the holders of the Notes.

  To the extent that any Domestic Guarantees are voided as a fraudulent
conveyance or held unenforceable for any other reason, holders of the Notes
would cease to have any claim in respect of such Domestic Guarantor and would be
creditors solely of the Issuer and any Domestic Guarantor whose Domestic
Guarantee was not voided or held unenforceable.  In such event, the claims of
the holders of the Notes against the issuer of an invalid Domestic Guarantee
would be subject to the prior payment of all liabilities and preferred equity
interests, if any, of such Domestic Guarantor.  Particularly given the fact that
the Issuer's 1997 pro forma EBITDA is not adequate to cover interest payments on
the Notes, there can be no assurance that, after providing for all prior claims
and preferred equity interests, if any, there would be sufficient assets to
satisfy the claims of the holders of the Notes relating to any voided portions
of any of the Domestic Guarantees.

  The measure of insolvency for these purposes will vary depending upon the law
of the jurisdiction being applied.  Generally, however, a company will be
considered insolvent for these purposes if the sum of that company's debts is
greater than all that company's property at a fair valuation, or if the present
fair salable value of that company's assets is less than the amount that would
be required to pay its probable liability on its existing debts as they become
absolute and matured.  Moreover, regardless of solvency, a court could avoid an
incurrence of indebtedness, including the Notes or a Domestic Guarantee, if it
determined that such transaction was made with intent to hinder, delay or
defraud creditors, or a court could subordinate the indebtedness, including the
Notes or a Domestic Guarantee, to the claims of all existing and future
creditors on similar grounds.

                                      -19-
<PAGE>
 
  Additionally, under U.S. federal bankruptcy or applicable state insolvency
law, if certain bankruptcy or insolvency proceedings were initiated by or
against the Issuer or a Domestic Guarantor within 90 days after any payment by
the Issuer with respect to the Notes or any payment by a Domestic Guarantor with
respect to the Domestic Guarantee or if the Issuer or a Domestic Guarantor
anticipated becoming insolvent at the time of such payment, all or a portion of
such payment could be avoided as a preferential transfer and the recipient of
such payment could be required to return such payment.

CANADIAN BANKRUPTCY AND RESTRUCTURING LAWS

  In Canada, the rights of the Trustee to enforce remedies are likely to be
significantly impaired by the restructuring provisions of applicable Canadian
federal bankruptcy, insolvency and other restructuring legislation if the
benefit of such legislation is sought with respect to the Issuer or a Canadian
Guarantor.  For example, both the Bankruptcy and Insolvency Act (Canada) and the
Companies' Creditors Arrangements Act (Canada) contain provisions enabling "an
insolvent person" to obtain a stay of proceedings against its creditors and
others and to prepare and file a proposal for consideration by all or some of
its creditors to be voted on by the various classes of its creditors.  Such a
restructuring proposal, if accepted by the requisite majorities of creditors and
if approved by the court, would be binding on persons who might not otherwise be
willing to accept it.  Moreover, such legislation permits, in certain
circumstances, the insolvent debtor to retain possession and administration of
its property, even though it may be in default under the applicable debt
instrument.

  The powers of a court under the Bankruptcy and Insolvency Act (Canada) and
particularly under the Companies' Creditor Arrangement Act (Canada) have been
exercised broadly to protect a restructuring entity from actions taken by
creditors and other parties.  Accordingly, it is impossible to predict if
payments under the Notes or any Canadian Guarantees would be made following
commencement of or during such a proceeding, whether or when the Trustee could
exercise its rights under the Indenture or whether and to what extent holders of
the Notes would be compensated for any delay in payments, if any, of principal
and interest.

  Additionally, under federal Canadian bankruptcy law, if certain bankruptcy or
insolvency proceedings were initiated by or against a Canadian Guarantor within
90 days after any payment by such Canadian Guarantor with respect to its
Guarantee or if such Canadian Guarantor anticipated becoming insolvent at the
time of such payment, all or a portion of such payment could be avoided as a
fraudulent preference and the recipient of such payment could be required to
return such payment.

YEAR 2000 SOFTWARE ISSUE

  The Company uses a number of computer software programs and operating systems
in its operations, including the PLUS/(R)/ system. To the extent that the
software applications used in such functions are unable to recognize the year
2000, the Company may incur expenses in connection with the need to remedy such
problem in the software and the associated risk and expense of any disruptions
that may be caused by the software's impaired functioning as the year 2000
approaches. The Company believes that the PLUS/(R)/ system will be year 2000
compliant by the end of 1998. The Company also believes that the manufacturers
of the software applications it uses most frequently, including its systems
software and its word processing and spreadsheet software, are in the process of
preparing or have already completed year 2000 remediations for their products.
In addition, the Company communicates electronically with a number of its
customers and vendors with respect to a variety of functions. Any failure of the
software of the Company's vendors or customers to address the year 2000 issue
could impair the Company's ability to perform such functions. The Company is
analyzing the potential impact of the year 2000 issue on the Company's software
and on the Company's interactions with its vendors and customers. Although the
Company believes that the expenses and capital expenditures associated with
achieving year 2000 compliance will not have a material adverse effect on the
Company's business and financial condition or results of operations, there can
be no assurance that the remediation costs and potential disruptions to the
Company's operations would not have a material adverse affect on the Company's
or the Issuer's business and financial condition or results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

                                      -20-

CASUALTY

  The Company currently maintains and intends to continue to maintain, to the
extent such insurance is available on commercially reasonable terms,
comprehensive liability, fire, flood and earthquake (where appropriate) and
extended coverage insurance with respect to the properties that it now owns or
leases or that it may in the future own or lease, with customary limits and
deductibles.  Certain types of loss, however, may not be fully insurable on a
cost-effective basis.  In the future, should uninsured losses or damages occur,
the Company could lose both its investment in and anticipated profits from the
affected property and may continue to be obligated on any leasehold obligations,
mortgage indebtedness or other obligations related to such property.  As a
result, any such material loss could materially adversely affect the Company and
the Issuer.  See "Business--Insurance."

ENVIRONMENTAL MATTERS

  The Company owns or leases approximately 16 million square feet of facilities.
Under various U.S. federal, state, local and foreign environmental laws,
regulations and ordinances ("environmental laws"), the Company's properties and
operations or former properties or locations may subject it to liability for the
costs of investigation, removal or remediation of soil and groundwater, on or
off-site, contaminated by hazardous substances and other contaminants or
hazardous materials such as petroleum products ("hazardous materials"), as well
as damages to natural resources.  Certain such laws impose cleanup
responsibility and liability without regard to whether the owner or operator of
the real estate or business thereon knew of or was responsible for the
contamination, and whether or not operations at the property have been
discontinued or title to the property has been transferred.  In addition, the
presence of such materials, or the failure to properly remediate such property,
may adversely affect the current property owner's or operator's ability to sell,
rent or use such property or to borrow using such property as collateral.  The
owner or operator of contaminated property also may be subject to statutory and
common law claims by third parties based on any damages and costs resulting from
off-site migration of the contamination.

  Certain environmental laws govern the removal, encapsulation or disturbance of
asbestos-containing materials ("ACMs") in buildings.  Such laws may impose
liability for improper handling and release of ACMs and third parties may seek
to recover from owners or operators of real estate for personal injury
associated with exposure to such materials.  Certain facilities operated by the
Company contain ACMs.

  Certain of the properties formerly or currently owned or operated by the
Company were previously used for industrial or other purposes that involved the
use or storage of hazardous materials or the generation and disposal of
hazardous wastes, and the use of underground storage tanks ("USTs") for
hazardous materials.  The Company has from time to time conducted certain
environmental investigations, and remedial activities have been performed, at
certain of its former and current properties, but an in-depth environmental
review of each of the properties and related operations has not been conducted
by or on behalf of the Company.  In connection with its former and current
ownership or operation of certain properties and businesses, the Company may be
subject to environmental liability as discussed above and as more specifically
described under "Business--Environmental Matters."

  The Company has not received any written notice from any governmental
authority or third party asserting, and is not otherwise aware of, any material
environmental non-compliance, liability or claim relating to hazardous materials
or otherwise under any environmental laws applicable to the Company in
connection with any of its present or former properties or operations other than
as described under "Business--Environmental Matters." However, no assurance can
be given that there are no environmental conditions for which the Company might
be liable in the future or that future regulatory action, or compliance with
future environmental laws, will not require the Company to incur costs with
respect to its properties or operations that could have a material adverse
effect on the Company's financial condition or results of operations.

CONTROL OF PIERCE LEAHY

                                      -21-
<PAGE>
 
  Members of the Pierce family who collectively own approximately 51% of the
shares of the Common Stock of Pierce Leahy have entered into a ten-year voting
trust agreement (the "Voting Trust Agreement") pursuant to which all of the
shares subject to the Voting Trust Agreement or related proxies are voted at the
direction of Leo W. Pierce, Sr. and J. Peter Pierce (the "Voting Trustees").
Consequently, the Voting Trustees are able to elect the Company's directors, to
determine the outcome of corporate actions requiring shareholder approval and
otherwise to control the business affairs of the Company.  See "Principal
Shareholders of Pierce Leahy Corp.--Voting Trust Agreement."

ABSENCE OF PUBLIC MARKET

  There is no existing trading market for the Notes, and the Company does not
intend to list any Notes on any securities exchange.  Although the Company has
been advised that the Initial Purchaser currently intends to make a market in
the Notes, the Initial Purchaser is not obligated to do so and may discontinue
any such market making at any time without notice.  In addition, any market
making activities in the Original Notes may be limited during the pendency of
the Exchange Offer.  There can be no assurance that an active trading market for
the Notes will develop, or, if it develops, that it will continue.  Future
trading prices for the Notes will depend on many factors, including, among other
things, the Company's operating results, the market for similar securities and
changes in prevailing interest rates.

PROCEDURES FOR TENDER OF ORIGINAL NOTES

  The Exchange Notes will be issued in substitution for Original Notes only
after timely receipt by the Exchange Agent of such Original Notes, a properly
completed and duly executed Letter of Transmittal and all other required
documents.  Therefore, holders of Original Notes desiring to tender such
Original Notes to be replaced by Exchange Notes should allow sufficient time to
ensure timely delivery.  Neither the Exchange Agent nor the Issuer is under any
duty to give notification of defects or irregularities with respect to tenders
of Original Notes for substitution.  Any holder of Original Notes who tenders in
the Exchange Offer for the purpose of participating in a distribution of the
Exchange Notes will be required to comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.  Each broker-dealer that receives Exchange Notes for its own
account in exchange for Notes, where such Original Notes were acquired by such
broker-dealer as a result of market-making activities or any other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes.  See "Plan of Distribution."

CONSEQUENCES OF FAILURE TO REPLACE ORIGINAL NOTES

  The Original Notes have not been registered under the Securities Act and are
subject to substantial restrictions on transfer. Original Notes that are not
tendered to be replaced by Exchange Notes or are tendered but not accepted will,
following consummation of the Exchange Offer, continue to be subject to the
existing restrictions upon transfer thereof. The Issuer does not currently
anticipate that it will register the Original Notes under the Securities Act. To
the extent that Original Notes are tendered and accepted in the Exchange Offer,
the trading market for untendered and tendered but unaccepted Original Notes
could be adversely affected. See "The Exchange-Consequences of Failure to
Exchange."

FORWARD-LOOKING STATEMENTS

  This Prospectus contains certain forward-looking statements within the meaning
of Section 27A of the Securities Act and Section 21E of the Exchange Act, and is

                              THE EXCHANGE OFFER

PURPOSES AND EFFECTS OF THE EXCHANGE OFFER

  The Original Notes were sold by the Issuer on April 7, 1998 (the "Issue Date")
to the Initial Purchasers pursuant to a Purchase Agreement dated as of April 2,
1998 (the "Purchase Agreement").  As a condition to the sale of the Original
Notes, the Issuer, Pierce Leahy and the Initial Purchaser entered into the
Registration Agreement on the Issue Date.  Pursuant to the Registration
Agreement, the Issuer agreed that, unless the Exchange Offer is not permitted by
applicable law or Commission policy, it would (i) file with the Commission a
Registration Statement under the Securities Act with respect to the Exchange
Notes within 90 days after the Issue Date, (ii) use its best efforts to cause
such Registration Statement to become effective under the Securities Act within
180 days after the Issue Date and (iii) upon effectiveness of the Registration
Statement, commence the Exchange Offer, keep the Exchange Offer open for at
least 30 days and not more than 45 days (or a longer period if required by law)
and deliver to the Exchange Agent Exchange Notes in the same aggregate principal
amount at maturity as the Original Notes that were tendered by holders thereof
pursuant to the Exchange Offer.  Under existing Commission interpretations, the
Exchange Notes would in general be freely transferable after the Exchange Offer
without further registration under the Securities Act; provided, that in the
case of broker-dealers, a prospectus meeting the requirements of the Securities
Act will be delivered as required.  The Issuer has agreed to make available a
prospectus meeting the requirements of the Securities Act to any broker-dealer
for use in connection with any resale of any such Exchange Notes acquired as
described below for such period of 180 days after the Expiration Date.  A
broker-dealer that delivers such a prospectus to purchasers in connection with
such resales will be subject to certain of the civil liability provisions under
the Securities Act, and will be bound by the Registration Agreement (including
certain indemnification rights and obligations).  A copy of the Registration
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part.  The Registration Statement of which this Prospectus
is a part is intended to satisfy certain of the Issuer's obligations under the
Registration Agreement and the Purchase Agreement.

  The Issuer is generally not required to file any registration statement to
register any outstanding Original Notes.  Holders of Original Notes who do not
tender their Original Notes or whose Original Notes are tendered but not
accepted will have to rely on exemptions to registration requirements under the
securities laws, including the Securities Act, if they wish to sell their
Original Notes.

  With respect to the Exchange Notes, based upon an interpretation by the staff
of the Commission set forth in certain no-action letters issued to third
parties, the Issuer believes that a holder (other than (i) a broker-dealer who
purchases such Exchange Notes directly from the Issuer to resell pursuant to
Rule 144A or any other available exemption under the Securities Act or (ii) any
such holder which is an "affiliate" of the Issuer within the meaning of Rule 405
under the Securities Act) who replaces Original Notes with Exchange Notes in the
ordinary course of business and who is not participating, does not intend to
participate, and has no arrangement with any person to participate, in the
distribution of the Exchange Notes, will be allowed to resell the Exchange Notes
to the public without further registration under the Securities Act and without
delivering to the purchasers of the Exchange Notes a prospectus that satisfies
the requirements of Section 10 of the Securities Act. However, if any holder
acquires the Exchange Notes in the Exchange Offer for the purpose of
distributing or participating in the distribution of the Exchange Notes or is a
broker-dealer, such holder cannot rely on the position of the staff of the
Commission enumerated in certain no-action letters issued to third parties and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction, unless an exemption
from registration is otherwise available. Each broker-dealer that receives
Exchange Notes for its own account in substitution for Original Notes, where
such Original Notes were acquired by such broker-dealer as a result of market-
making activities or other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in substitution for
Original Notes where such Original Notes were acquired by such broker-dealer as
a result of market-making or other trading activities. Pursuant to the
Registration Agreement, the Issuer has agreed to make this Prospectus, as it may
be

                                      -24-
<PAGE>
 
amended or supplemented from time to time, available to broker-dealers for use
in connection with any resale for a period of 180 days after the Expiration
Date. See "Plan of Distribution."

TERMS OF THE EXCHANGE OFFER

  Upon the terms and subject to the conditions set forth in this Prospectus and
in the accompanying Letter of Transmittal, the Issuer will accept any and all
Original Notes validly tendered and not withdrawn prior to the Expiration Date.
The Issuer will issue $1,000 principal amount of Exchange Notes in substitution
for each $1,000 principal amount of outstanding Original Notes surrendered
pursuant to the Exchange Offer.  Holders may tender some or all of their
Original Notes pursuant to the Exchange Offer; provided, however, that Original
Notes may be tendered only in integral multiples of $1,000.  The Exchange Offer
is not conditioned upon any minimum aggregate principal amount of Original Notes
being tendered for substitution.

  The form and terms of the Exchange Notes are the same as the form and terms of
the Original Notes except that (i) the Exchange Notes will be registered under
the Securities Act and, therefore, will not bear legends restricting their
transfer and (ii) holders of the Exchange Notes will not be entitled to the
certain rights of holders of Original Notes under the Registration Agreement,
which rights will terminate upon the consummation of the Exchange Offer.  The
Exchange Notes will evidence the same debt as the Original Notes (which they
replace) and will be issued under, and be entitled to the benefits of, the
Indenture, which also authorized the issuance of the Original Notes, such that
all outstanding Notes will be treated as a single class of debt securities under
the Indenture.

  Interest on the Exchange Notes will accrue from the most recent date to which
interest has been paid on the Original Notes or, if no interest has been paid,
from April 7, 1998.  Accordingly, registered holders of Exchange Notes on the
relevant record date for the first interest payment date following the
consummation of the Exchange Offer will receive interest accruing from the most
recent date to which interest has been paid or, if no interest has been paid,
from April 7, 1998.  Original Notes accepted for substitution will cease to
accrue interest from and after the date of the consummation of the Exchange
Offer.  Holders whose Original Notes are accepted for substitution will not
receive any payment in respect of interest on such Original Notes otherwise
payable on any interest payment date, the record date for which occurs on or
after consummation of the Exchange Offer.

  As of the date of this Prospectus, $135,000,000 aggregate principal amount of
the Original Notes are outstanding and registered in the name of Cede & Co., as
nominee for the Depository Trust Company (the "Depository" or "DTC").  Only a
registered holder of the Original Notes (or such holder's legal representative
or attorney-in-fact) as reflected on the records of the Trustee under the
Indenture may participate in the Exchange Offer.  There will be no fixed record
date for determining registered holders of the Original Notes entitled to
participate in the Exchange Offer.

  Holders of the Original Notes do not have any appraisal or dissenters' rights
under the Indenture in connection with the Exchange Offer.  The Issuer intends
to conduct the Exchange Offer in accordance with the provisions of the
Registration Agreement and the applicable requirements of the Securities Act,
the Exchange Act and the rules and regulations of the Commission thereunder.

  The Issuer shall be deemed to have accepted validly tendered Original Notes
when, as and if the Issuer has given oral or written notice thereof to the
Exchange Agent.  The Exchange Agent will act as agent for the tendering holders
of Original Notes for the purposes of receiving the Exchange Notes from the
Issuer.

  If any tendered Original Notes are not accepted for substitution because of an
invalid tender, or due to the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Original Notes will be
returned without expense to the tendering holders thereof (or in the case of
Original Notes tendered by book-entry transfer, such Original Notes will be
credited to the account of such holder maintained at the Depository), as
promptly as practicable after the expiration or termination of the Exchange
Offer.

                                      -25-
<PAGE>
 
  Holders who tender Original Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the replacement of Notes
pursuant to the Exchange Offer.  The Issuer will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer.  See "The Exchange Offer-Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; TERMINATION

  The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
November 10, 1998 unless the Issuer, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.

  In order to extend the Exchange Offer the Issuer will notify the Exchange
Agent of any extension by oral (promptly confirmed in writing) or written notice
and will make a public announcement thereof, each prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled expiration
date of the Exchange Offer.  Without limiting the manner in which the Issuer may
choose to make a public announcement of any delay, extension, amendment or
termination of the Exchange Offer, the Issuer shall have no obligation to
publish, advertise or otherwise communicate any such public announcement, other
than by making a timely release to an appropriate news agency.

  The Issuer reserves the right, in its sole discretion, (i) to delay accepting
any Original Notes, (ii) to extend the Exchange Offer, (iii) if any conditions
set forth below under "-Certain Conditions to the Exchange Offer" shall not have
been satisfied, to terminate the Exchange Offer by giving oral or written notice
of such delay, extension or termination to the Exchange Agent or (iv) to amend
the terms of the Exchange Offer in any manner.  Any such delay in acceptance,
extension, termination or amendment will be followed as promptly as practicable
by oral or written notice thereof to the registered holders.  If the Exchange
Offer is amended in a manner determined by the Issuer to constitute a material
change, the Issuer will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the registered holders of
Original Notes, and the Issuer will extend the Exchange Offer for a period of
five to ten business days, depending upon the significance of the amendment and
the manner of disclosure to such registered holders, if the Exchange Offer would
otherwise expire during such five to ten business day period.  The rights
reserved by the Issuer in this paragraph are in addition to the Issuer's rights
set forth below under the caption "--Certain Conditions of the Exchange Offer."

  If the Issuer extends the period of time during which the Exchange Offer is
open, or if it is delayed in accepting for replacement of, or in issuing and
substituting the Exchange Notes for, any Original Notes, or is unable to accept
for substitution, or issue Exchange Notes for, any Original Notes pursuant to
the Exchange Offer for any reason, then, without prejudice to the Issuer's
rights under the Exchange Offer, the Exchange Agent may, on behalf of the
Issuer, retain all Original Notes tendered, and such Original Notes may not be
withdrawn except as otherwise provided below in "--Withdrawal of Tenders."  The
adoption by the Issuer of the right to delay acceptance for replacement of, or
the issuance and the replacement of the Exchange Notes, for any Original Notes
is subject to applicable law, including Rule 14e-1(c) under the Exchange Act,
which requires that the Issuer pay the consideration offered or return the
Original Notes deposited by or on behalf of the holders thereof promptly after
the termination or withdrawal of the Exchange Offer.

PROCEDURES FOR TENDERING

  Only a registered holder of Original Notes may tender such Original Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder must complete,
sign and date the Letter of Transmittal, or facsimile thereof, have the
signature thereon guaranteed if required by the Letter of Transmittal and mail
or otherwise deliver such Letter of Transmittal or such facsimile to the
Exchange Agent at the address set forth below under "The Exchange Offer-Exchange
Agent" for receipt prior to the Expiration Date. In addition, either (i)
certificates for such Notes must be received by the Exchange Agent along with
the Letter of Transmittal, or (ii) a timely confirmation of a book-entry
transfer of such Notes, if such procedure is available, into the Exchange
Agent's account at DTC pursuant to the procedure for book-entry transfer

                                      -26-
<PAGE>
 
described below, must be received by the Exchange Agent prior to the Expiration
Date, or (iii) the holder must comply with the guaranteed delivery procedures
described below.

  Any financial institution that is a participant in the Depository's Book-Entry
Transfer Facility system may make book-entry delivery of the Original Notes by
causing the Depository to transfer such Original Notes into the Exchange Agent's
account in accordance with the Depository's procedure for such transfer.
Although delivery of Original Notes may be effected through book-entry transfer
into the Exchange Agent's account at the Depository, the Letter of Transmittal
(or facsimile thereof), with any required signature guarantees and any other
required documents, must, in any case, be transmitted to and received or
confirmed by the Exchange Agent at its addresses set forth under "-Exchange
Agent" below prior to 5:00 p.m., New York City time, on the Expiration Date.
DELIVERY OF DOCUMENTS TO THE DEPOSITORY IN ACCORDANCE WITH ITS PROCEDURES DOES
NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

  The tender by a holder which is not withdrawn prior to the Expiration Date
will constitute a binding agreement between such holder and the Issuer in
accordance with the terms and subject to the conditions set forth herein and in
the Letter of Transmittal.

  THE METHOD OF DELIVERY OF NOTES AND THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER.  INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED.  IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE
EXCHANGE AGENT BEFORE THE EXPIRATION DATE.  NO LETTER OF TRANSMITTAL OR NOTES
SHOULD BE SENT TO THE ISSUER.  HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS,
DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE
TRANSACTIONS FOR SUCH HOLDERS.

  Any beneficial owner of the Original Notes whose Original Notes are registered
in the name of a broker, dealer, commercial bank, trust company or other nominee
and who wishes to tender should contact the registered holder promptly and
instruct such registered holder to tender on such beneficial owner's behalf.  If
such beneficial owner wishes to tender on such owner's own behalf, such owner
must, prior to completing and executing the Letter of Transmittal and delivering
such owner's Original Notes, either make appropriate arrangements to register
ownership of the Notes in such owner's name (to the extent permitted by the
Indenture) or obtain a properly completed assignment from the registered holder.
The transfer of registered ownership may take considerable time.

  If the Letter of Transmittal is signed by a person other than the registered
holder of any Original Notes (which term includes any participants in DTC whose
name appears on a security position listing as the owner of the Original Notes)
or if delivery of the Exchange Notes is to be made to a person other than the
registered holder, such Original Notes must be endorsed or accompanied by a
properly completed bond power, in either case signed by such registered holder
as such registered holder's name appears on such Original Notes with the
signature on the Original Notes or the bond power guaranteed by an Eligible
Institution (as defined below).

  Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "-Withdrawal of Tenders"), as the case may be, must be guaranteed by
an Eligible Institution unless the Original Notes tendered pursuant thereto are
tendered (i) by a registered holder who has not completed the box entitled
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter of
Transmittal or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantee must be made by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States, or another "Eligible Guarantor Institution"
within the meaning of Rule 17Ad-15 under the Exchange Act (any of the foregoing,
an "Eligible Institution").

                                      -27-
<PAGE>
 
  If the Letter of Transmittal or any Original Notes or assignments are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Issuer,
evidence satisfactory to the Issuer of their authority to so act must be
submitted with the Letter of Transmittal.

  The Exchange Agent and the Depository have confirmed that any financial
institution that is a participant in the Depository's system may utilize the
Depository's Automated Tender Offer Program to tender Original Notes.

  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Notes will be
determined by the Issuer in its sole discretion, which determination will be
final and binding.  The Issuer reserves the absolute right to reject any and all
Original Notes not properly tendered or any Original Notes, the Issuer's
acceptance of which would, in the opinion of counsel for the Issuer, be
unlawful.  The Issuer also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Notes.  The Issuer's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in the Letter of Transmittal) will be final and binding on all
parties.  Unless waived, any defects or irregularities in connection with
tenders of Original Notes must be cured within such time as the Issuer shall
determine.  Although the Issuer intends to request the Exchange Agent to notify
holders of defects or irregularities with respect to tenders of Original Notes,
neither the Issuer, the Exchange Agent nor any other person shall incur any
liability for failure to give such notification.  Tenders of Original Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived.

  While the Issuer has no present plan to acquire any Original Notes which are
not tendered in the Exchange Offer or to file a registration statement to permit
resales of any Original Notes which are not tendered pursuant to the Exchange
Offer, the Issuer reserves the right in its sole discretion to purchase or make
offers for any Original Notes that remain outstanding subsequent to the
Expiration Date or, as set forth below under "-Certain Conditions to the
Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by
applicable law, purchase Original Notes in the open market, in privately
negotiated transactions or otherwise.  The terms of any such purchases or offers
could differ from the terms of the Exchange Offer.

  By tendering, each holder will represent to the Issuer that, among other
things, (i) the Exchange Notes to be acquired by the holder of the Original
Notes in connection with the Exchange Offer are being acquired by the holder in
the ordinary course of business of the holder, (ii) the holder has no
arrangement or understanding with any person to participate in the distribution
of Exchange Notes, (iii) the holder acknowledges and agrees that any person who
is a broker-dealer registered under the Exchange Act or is participating in the
Exchange Offer for the purpose of distributing the Exchange Notes must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with a secondary resale transaction of the Exchange Notes acquired
by such person and cannot rely on the position of the staff of the Commission
set forth in certain no-action letters, (iv) the holder understands that a
secondary resale transaction described in clause (iii) above and any resales of
Exchange Notes obtained by such holder in exchange for Original Notes acquired
by such holder directly from the Issuer should be covered by an effective
registration statement containing the selling securityholder information
required by Item 507 or Item 508, as applicable, of Regulation S-K of the
Commission, and (v) the holder is not an "affiliate," as defined in Rule 405 of
the Securities Act, of the Issuer. If the holder is a broker-dealer that will
receive Exchange Notes for its own account in substitution for Original Notes
that were acquired as a result of market-making activities or other trading
activities, the holder is required to acknowledge in the Letter of Transmittal
that it will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the holder
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.

RETURN OF NOTES

  If any tendered Original Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Original Notes are
withdrawn or are submitted for a greater principal amount than the holders
desire to replace, such unaccepted, withdrawn or non-substituted Original Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Original Notes tendered by book-entry transfer into the Exchange Agent's
account at 

                                      -28-
<PAGE>
 
the Depository pursuant to the book-entry transfer procedures described below,
such Original Notes will be credited to an account maintained with the
Depository) as promptly as practicable.

BOOK-ENTRY TRANSFER

  The Exchange Agent will make a request to establish an account with respect to
the Original Notes at the Depository for purposes of the Exchange Offer within
two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depository's system may make book-entry
delivery of Original Notes by causing the Depository to transfer such Original
Notes into the Exchange Agent's account at the Depository in accordance with the
Depository's procedures for transfer.  However, although delivery of Original
Notes may be effected through book-entry transfer at the Depository, the Letter
of Transmittal or facsimile thereof, with any required signature guarantees and
any other required documents, must, in any case, be transmitted to and received
by the Exchange Agent at the address set forth below under "-Exchange Agent" on
or prior to the Expiration Date or pursuant to the guaranteed delivery
procedures described below.

GUARANTEED DELIVERY PROCEDURES

  Holders who wish to tender their Original Notes and (i) whose Original Notes
are not immediately available or (ii) who cannot deliver their Original Notes
(or complete the procedures for book-entry transfer), the Letter of Transmittal
or any other required documents to the Exchange Agent prior to the Expiration
Date, may effect a tender if:

     (a)  the tender is made through an Eligible Institution;

     (b)  prior to the Expiration Date, the Exchange Agent receives from such
   Eligible Institution a properly completed and duly executed Notice of
   Guaranteed Delivery substantially in the form provided by the Issuer (by
   facsimile transmission, mail or hand delivery) setting forth the name and
   address of the holder, the certificate number(s) of such Original Notes (if
   available) and the principal amount of Original Notes tendered, stating that
   the tender is being made thereby and guaranteeing that, within five New York
   Stock Exchange trading days after the Expiration Date, the Letter of
   Transmittal (or a facsimile thereof) together with the certificate(s)
   representing the Original Notes in proper form for transfer (or a
   confirmation of a book-entry transfer into the Exchange Agent's account at
   the Depository of Original Notes delivered electronically), and any other
   documents required by the Letter of Transmittal will be deposited by the
   Eligible Institution with the Exchange Agent; and

     (c)  such properly executed Letter of Transmittal (or facsimile thereof), 
   as well as the certificate(s) representing all tendered Original Notes in
   proper form for transfer (or a confirmation of a book-entry transfer into the
   Exchange Agent's account at the Depository of Original Notes delivered
   electronically), and all other documents required by the Letter of
   Transmittal are received by the Exchange Agent within five New York Stock
   Exchange trading days after the Expiration Date.

  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Original Notes according to the
guaranteed delivery procedures set forth above.

WITHDRAWAL OF TENDERS

  Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time prior to the Expiration Date.

  To withdraw a tender of Original Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date.  Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Original Notes to be withdrawn, (ii) identify the Original Notes to be
withdrawn (including the certificate number or numbers (if applicable) and
principal amount of such Original Notes), and (iii) be signed by the holder in
the same manner as the original signature 

                                      -29-
<PAGE>
 
on the Letter of Transmittal by which such Original Notes were tendered
(including any required signature guarantees). All questions as to the validity,
form and eligibility (including time of receipt) of such notices will be
determined by the Issuer in its sole discretion, whose determination shall be
final and binding on all parties. Any Original Notes so withdrawn will be deemed
not to have been validly tendered for purposes of the Exchange Offer and no
Exchange Notes will be issued with respect thereto unless the Original Notes so
withdrawn are validly retendered. Properly withdrawn Notes may be retendered by
following one of the procedures described above under "-Procedures for
Tendering" at any time prior to the Expiration Date.

CERTAIN CONDITIONS TO THE EXCHANGE OFFER

  Notwithstanding any other term of the Exchange Offer, the Issuer shall not be
required to accept for replacement, or substitute the Exchange Notes for, any
Original Notes not theretofore accepted for replacement, and may terminate or
amend the Exchange Offer as provided herein before the acceptance of such
Original Notes, if any of the following conditions exist:

(a) any action or proceeding is instituted or threatened in any court or by or
before any governmental agency with respect to the Exchange Offer which, in the
reasonable judgment of the Issuer, might impair the ability of the Issuer to
proceed with the Exchange Offer or have a material adverse effect on the
contemplated benefits of the Exchange Offer to the Issuer or there shall have
occurred any material adverse development in any existing action or proceeding
with respect to the Issuer or any of its subsidiaries; or

     (b)  there shall have been any material change, or development involving a
   prospective change, in the business or financial affairs of the Issuer or any
   of its subsidiaries which, in the reasonable judgment of the Issuer, could
   reasonably be expected to materially impair the ability of the Issuer to
   proceed with the Exchange Offer or materially impair the contemplated
   benefits of the Exchange Offer to the Issuer; or

     (c)  there shall have been proposed, adopted or enacted any law, statute,
   rule or regulation which, in the judgment of the Issuer, could reasonably be
   expected to materially impair the ability of the Issuer to proceed with the
   Exchange Offer or materially impair the contemplated benefits of the Exchange
   Offer to the Issuer; or

     (d)  any governmental approval which the Issuer shall, in its reasonable
   discretion, deem necessary for the consummation of the Exchange Offer as
   contemplated hereby shall have not been obtained.

  If the Issuer determines in its reasonable discretion that any of these
conditions are not satisfied, the Issuer may (i) refuse to accept any Original
Notes and return all tendered Original Notes to the tendering holders, (ii)
extend the Exchange Offer and retain all Original Notes tendered prior to the
expiration of the Exchange Offer, subject, however, to the rights of holders to
withdraw such Original Notes (see "The Exchange Offer-Withdrawal of Tenders") or
(iii) waive such unsatisfied conditions with respect to the Exchange Offer and
accept all properly tendered Original Notes which have not been withdrawn.  If
such waiver constitutes a material change to the Exchange Offer, the Issuer will
promptly disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders of the Original Notes, and the Issuer will
extend the Exchange Offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the
registered holders, if the Exchange Offer would otherwise expire during such
five to ten business day period.

  Holders may have certain rights and remedies against the Issuer under the
Registration Agreement should the Issuer fail to consummate the Exchange Offer,
notwithstanding a failure of the conditions stated above.  Such conditions are
not intended to modify those rights or remedies in any respect.

  The foregoing conditions are for the sole benefit of the Issuer and may be
asserted by the Issuer regardless of the circumstances giving rise to such
condition or may be waived by the Issuer in whole or in part at any time and
from time to time in the Issuer's reasonable discretion.  The failure by the
Issuer at any time to exercise the foregoing rights shall 

                                      -30-
<PAGE>
 
period of five to ten business days, depending upon the significance of the
waiver and the manner of disclosure to the registered holders, if the Exchange
Offer would otherwise expire during such five to ten business day period.

     Holders may have certain rights and remedies against the Issuer under the
Registration Agreement should the Issuer fail to consummate the Exchange Offer,
notwithstanding a failure of the conditions stated above.  Such conditions are
not intended to modify those rights or remedies in any respect.

     The foregoing conditions are for the sole benefit of the Issuer and may be
asserted by the Issuer regardless of the circumstances giving rise to such
condition or may be waived by the Issuer in whole or in part at any time and
from time to time in the Issuer's reasonable discretion.  The failure by the
Issuer at any time to exercise the foregoing rights shall not be deemed a waiver
of any such right and each such right shall be deemed an ongoing right which may
be asserted at any time and from time to time.

TERMINATION OF CERTAIN RIGHTS

     All rights under Registration Agreement (including registration rights) of
holders of the Original Notes eligible to participate in this Exchange Offer
will terminate upon consummation of the Exchange Offer except with respect to
the Issuer's continuing obligations (i) to indemnify the holders (including any
broker-dealers) and certain parties related to the holders against certain
liabilities (including liabilities under the Securities Act), (ii) to provide,
upon the request of any holder of a transfer-restricted Original Note, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Original Notes pursuant to Rule 144A, (iii) to use its
best efforts to keep the Registration Statement effective to the extent
necessary to ensure that it is available for resales of transfer-restricted
Notes by broker-dealers for a period of 180 days from the Expiration Date and
(iv) to provide copies of the latest version of the Prospectus to broker-dealers
upon their request for a period of 180 days from the Expiration Date.  Insofar
as indemnification for liabilities arising under the Securities Act may be
permitted pursuant to the foregoing provisions, the Issuer has been informed
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

Offer.  All questions and requests for assistance as well as all correspondence

FEES AND EXPENSES

     The expenses of soliciting tenders will be borne by the Issuer. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers and regular
employees of the Issuer and its affiliates.

     The Issuer has not retained any dealer-manager or other soliciting agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptance of the Exchange Offer.  The Issuer will,
however, pay the Exchange Agent reasonable and customary fees for its services
and will reimburse it for its reasonable out-of-pocket expenses in connection
therewith.

     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Issuer and are estimated in the aggregate to be approximately
$150,000. Such expenses include fees and expenses of the Exchange Agent and
Trustee, accounting and legal fees and printing costs, among others.

     The Issuer will pay all transfer taxes, if any, applicable to the
replacement of Original Notes pursuant to the Exchange Offer. If, however,
certificates representing Exchange Notes, or Original Notes for principal
amounts not tendered or acceptable for replacement, are to be delivered to, or
are to be issued in the name of, any person other than the registered holders of
the Original Notes tendered, or if tendered Original Notes are registered in the
name of any person other than the person signing the Letter of Transmittal, or
if a transfer tax is imposed for any reason other than the replacement of
Original Notes pursuant to the Exchange Offer, then the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder of Original Notes.

ACCOUNTING TREATMENT

     The Exchange Notes evidence the same debt as the Original Notes and will be
recorded at the same carrying value as the Original Notes as reflected in the
Issuer's accounting records on the date of the replacement.  Accordingly, no
gain or loss for accounting purposes will be recognized.  The expenses of the
Exchange Offer will be amortized over the term of the Exchange Notes.

CONSEQUENCE OF FAILURE TO TENDER

     Participation in the Exchange Offer is voluntary.  Holders of the Original
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.

     The Original Notes which are not replaced by the Exchange Notes pursuant to
the Exchange Offer will remain restricted securities.  Accordingly, such
Original Notes may be resold only (i) to a person whom the seller reasonably
believes is a qualified institutional buyer (as defined in Rule 144A under the
Securities Act) in a transaction meeting the requirements of Rule 144A, (ii) in
a transaction meeting the requirements of Rule 144 under the Securities Act,
(iii) outside the United States to a foreign person in a transaction meeting the
requirements of Rule 904 under the Securities Act, (iv) in accordance with
another exemption from the registration requirements of the Securities Act (and
based upon an opinion of counsel if the Issuer so requests), (v) to the Issuer
or (vi) pursuant to an effective registration statement and, in each case, in
accordance with any applicable securities laws of any state of the United States
or any other applicable jurisdiction.

                                  THE COMPANY

     Pierce Leahy is a Pennsylvania corporation. It was originally incorporated
in New York in 1990 and, pursuant to a merger, was redomesticated into
Pennsylvania in 1997 in connection with Pierce Leahy's initial public offering
of shares of its Common Stock.

                                      -32-
<PAGE>
 
     Pierce Leahy's operations date to 1957 when its predecessor company, L.W.
Pierce Co., Inc., was founded to provide filing systems and related equipment to
companies in the Philadelphia area.  L. W. Pierce Co., Inc. expanded primarily
through internal growth until 1990 when it acquired Britannia Security Group,
Inc. (doing business as Leahy Business Archives), which approximately doubled
the size of the Company.  Pierce Leahy was formed at that time from the
consolidation of the predecessor company with Leahy Business Archives.

     The principal executive offices of Pierce Leahy are located at 631 Park
Avenue, King of Prussia, Pennsylvania 19406, and its telephone number is (610)
992-8200.

                                  THE ISSUER

     Pierce Leahy entered the Canadian records storage market through the
purchase of Command Records Services Limited in 1995. Pierce Leahy formed the
Issuer, Pierce Leahy Command Company, a Nova Scotia unlimited liability company,
in 1995 to acquire such business. As a result of Pierce Leahy's status as a
Subchapter S corporation for federal income tax purposes at the time of the
formation of the Issuer, all of the capital stock of the Issuer is owned by two
Pennsylvania limited partnerships. Two separate corporations owned by J. Peter
Pierce, the Company's President and Chief Executive Officer, are the general
partner of each partnership, respectively, and Pierce Leahy has a 99% limited
partnership interest in each partnership. Accordingly, Pierce Leahy has an
indirect 99% equity interest in the Issuer.

     Prior to the Archivex Acquisition, the Issuer operated a total of 17
records management facilities in five of the six largest markets in Canada
(Calgary, Montreal, Ottawa, Toronto and Vancouver). Concurrently with the
Offering, the Company acquired substantially all of the assets of Archivex Inc.,
a Canadian corporation, with a portion of the proceeds of the Offering. Archivex
Inc. has operations in six Canadian cities, including three markets in which the
Issuer previously operated (Calgary, Montreal and Toronto) and three markets in
which the Issuer did not previously have a presence (Edmonton, Quebec City and
Winnipeg). A newly formed wholly-owned subsidiary of Pierce Leahy, Archivex
Limited, purchased and operates the assets of Archivex Inc. in Montreal,
including four records management facilities. Command purchased the remaining
assets of Archivex Inc. Since the consummation of the Archivex Acquisition, the
Issuer operates 30 records management facilities in the nine largest markets in
Canada. The aggregate cash consideration for the Archivex Acquisition, which
represented a significant expansion in the Canadian market for the Company, was
approximately $63.0 million. Included in the Archivex Acquisition were six owned
records storage facilities with in excess of an aggregate of 600,000 square feet
of space and five leased records storage facilities with approximately 100,000
square feet of space. The Archivex Acquisition added approximately 4.0 million
cubic feet of records under management.

     The principal executive offices of Command are located at 1303 Greene
Avenue, Suite 303, Montreal, Quebec H3Z 2A4, Canada, and its telephone number is
(514) 934-0273.

                                USE OF PROCEEDS

     The Issuer will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby.  In consideration for issuing the Exchange Notes
as contemplated in this Prospectus, the Issuer will receive in substitution
Original Notes in like principal amount, the terms of which are substantially
identical to the Exchange Notes and which evidence the same debt as the Exchange
Notes.  The Original Notes surrendered in substitution for Exchange Notes will
be retired and cancelled and cannot be reissued.  Accordingly, issuance of the
Exchange Notes will not result in any increase in the indebtedness of the Issuer
or the Company.

     The net proceeds to the Issuer from the sale of the Original Notes were
estimated to be approximately $131.8 million, after deducting underwriting fees
and estimated offering expenses.  The Issuer has used or expects to use the net
proceeds of the Offering as follows: (i) approximately $66 million to fund the
Archivex Acquisition (including approximately $20 million of such total amount
loaned to Archivex to fund its portion of the Archivex Acquisition), which
amount includes approximately $3 million of related integration costs; (ii)
approximately $25 million to repay 

                                      -33-
<PAGE>
 
the Issuer's outstanding borrowings under the Credit Facility; (iii)
approximately $11 million to repay outstanding loans from Pierce Leahy; (iv)
approximately $4 million to return capital invested by Pierce Leahy in the
Issuer; and (v) the balance of the net proceeds was lent to Pierce Leahy, which
amount Pierce Leahy used to repay a portion of its borrowings under the Credit
Facility. As of July 31, 1998, the effective interest rate on the U.S. dollar
portion of the Credit Facility was approximately 7.77%. The borrowings by the
Issuer under the Credit Facility which were repaid by a portion of the net
proceeds of the Offering were primarily used to fund certain of the Company's
acquisitions and for working capital. The borrowings by Pierce Leahy under the
Credit Facility which it repaid with a portion of the proceeds of the Offering
were primarily used to fund acquisitions.

The following table sets forth the capitalization of the Company as of June 30,
1998 (i) on an actual basis and (ii) on a pro forma basis to give effect to the
Recent Acquisitions as if they had occurred as of June 30, 1998.  The Offering
was completed in April 1998 and the effects of the Offering and the application
of the net proceeds therefrom as described in the "Use of Proceeds" are
reflected in the June 30, 1998 actual amounts.  This table should be read in
conjunction with the Company's Pro Forma Financial Data and Consolidated

                PRO FORMA FINANCIAL DATA OF PIERCE LEAHY CORP.

  The unaudited Pro Forma Condensed Consolidated Balance Sheet as of June 30,
1998 gives effect to the Recent Acquisitions as if they occurred on June 30,
1998. The Unaudited Pro Forma Condensed Consolidated Statements of Operations
for the year ended December 31, 1997 and for the six months ended June 30, 1998
give effect to, among other things, the 1997 and 1998 Acquisitions for periods
prior to their acquisition by the Company and the Offering, as if they occurred
on January 1, 1997.  The Company recorded a deferred income tax provision of
$6,600 in 1997 in connection with the termination of the Company's status as a
Subchapter S corporation for the tax effect of differences in the basis of
assets and liabilities for financial reporting and income tax purposes.  This
one-time deferred income tax provision has been eliminated in the December 31,
1997 Pro Forma Condensed Consolidated Statement of Operations.

  The 1997 and 1998 Acquisitions, the Offering and certain management
assumptions and adjustments are described in the accompanying notes hereto. This
pro forma information is not necessarily indicative of the results that would
have occurred had the 1997 and 1998 Acquisitions and the Offering been completed
on the dates indicated or of the Company's actual or future results or financial
position. The unaudited Pro Forma Condensed Consolidated Balance Sheet and
Statements of Operations should be read in conjunction with the Company's
Consolidated Financial Statements and notes thereto, as of December 31, 1997 and
for each of the three years in the period ended December 31, 1997, incorporated
by reference into this Prospectus.

       NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET

                                 JUNE 30, 1998
                            (DOLLARS IN THOUSANDS)


(a) Represents the balance sheets for the Recent Acquisitions other than the
    Kestrel Acquisition (see "Business-The 1998 Acquisitions") after the
    application of the purchase method of accounting. The cash purchase price of
    the 1998 Acquisitions (excluding the Kestrel Acquisition) was approximately
    $9,082.


(b) The Company completed the Kestrel Acquisition after June 30, 1998 (see
    "Business The Kestrel Acquisition") for approximately $52,000 including
    transaction costs. The pro forma adjustments reflect the application of the
    purchase method of accounting to the actual balance sheet of Kestrel.


(c) Intangible assets include goodwill ($30,636) and a noncompete agreement
    ($5,000) which resulted from the preliminary allocation of the purchase
    price. These intangibles are subject to adjustment based on the final
    allocation of the purchase price to the net assets acquired. Management
    believes that the final allocation of the purchase price will not differ
    materially from the preliminary estimated amounts.


(d) Reflects the Company's assumed additional borrowing of $52,000 under the
    Credit Facility to fund the Kestrel Acquisition.


(e) Reflects elimination of long-term debt and noncompete obligations not
    assumed as part of the Kestrel Acquisition.


(f) Reflects the resetting of deferred rent upon application of the purchase
    method of accounting.


(g) Reflects the adjustment to eliminate historical equity accounts of Kestrel.

              NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                           STATEMENTS OF OPERATIONS

                            (DOLLARS IN THOUSANDS)

(a)  Represents the historical results of operations of the 1997 and 1998
     Acquisitions for the periods from January 1, 1997 to the earlier of their
     dates of acquisition by the Company or June 30, 1998. See "Business--
     Acquisition and Growth Strategy," "Business--The 1998 Acquisitions" and
     "Business The Kestrel Acquisition."

(b)  Management expects to achieve cost savings from the 1997 and 1998
     Acquisitions as a result of the factors described below. The Pro Forma
     Condensed Consolidated Statements of Operations for the year ended December
     31, 1997 and the six months ended June 30, 1998 reflect only the cost
     savings actually achieved in 1997 and in the six months ended June 30, 1998
     from the acquisitions completed in 1997 and in the six months ended June
     30, 1998 and none of the additional expected savings from the 1997 and 1998
     Acquisitions. There is typically a lag after an acquisition is completed to
     fully realize such savings and the Company expects to achieve additional
     savings from the 1997 and 1998 Acquisitions.

     The integration of an acquired company entails, among other things,
     converting the database of stored records to the PLUS(R) system,
     reorganizing archive operating activities and eliminating certain back
     office activities which can be handled through the PLUS(R) system or the
     Company's centralized corporate organization. Cost savings start to be
     realized a short time after an acquisition. Management has specifically
     identified approximately $15,381 and $2,628 of estimated operating expenses
     included in the Pro Forma Statements of Operations for the year ended
     December 31, 1997 and for the six months ended June 30, 1998 that would not
     have been incurred had the 1997 and 1998 Acquisitions occurred as of
     January 1, 1997 and had such cost savings been fully implemented as of such
     date. These savings relate to (i) the termination of certain employees due
     to the efficiency of the PLUS(R) system and integration and consolidation
     of facilities, (ii) a reduction in warehouse rent expense related to
     facilities the Company has vacated or will vacate or has negotiated changes
     in lease terms and (iii) a reduction of other operating costs due to the
     Company's economies of scale. Management expects to realize additional cost
     savings beyond the $15,381 and $2,628 specifically identified.

(c)  Represents the elimination of rent expense on facilities leased to Archivex
     Inc. from its affiliates.  These facilities were purchased as part of the
     Archivex Acquisition.

(d)  Represents the elimination of management fees paid to an affiliate of
     Archivex Inc. which fees were discontinued upon completion of the Archivex
     Acquisition.

(e)  A pro forma adjustment has been made to reflect additional depreciation and
     amortization expense based on the estimated fair value of the assets
     acquired, as if the 1997 and 1998 Acquisitions had occurred as of January
     1, 1997. Such depreciation and amortization has been recorded in accordance
     with the Company's accounting policies as stated in Notes 3 and 4 of Notes
     to Consolidated Financial Statements incorporated by reference herein. The
     purchase price allocation may change upon the final appraisal of the fair
     market value of the net assets acquired. However, management believes that
     any change in value will not materially impact the amount of depreciation
     and amortization recorded.

(f)  Represents interest expense for the year ended December 31, 1997 and for
     the six months ended June 30, 1998, respectively, on debt incurred to
     finance the 1997 and 1998 Acquisitions, using an annual interest rate of
     7%.

(g)  Reflects interest expense on $130,000 of the 1996 Notes at 111/8%, $120,000
     of the 1997 Notes at 91/8%, $135,000 of the Notes at 81/8%, and, with
     respect to the year ended December 31, 1997 and the six months ended June
     30, 1998, interest expense of $3,919 and $1,960 on existing and assumed
     Senior Indebtedness, interest expense of $394 and $197 on other pro forma
     indebtedness, commitment fees on existing Senior Indebtedness of $433 and
     $217 and amortization of deferred financing costs of $1,426 and $713,
     respectively.

(h)  The Company recorded a deferred income tax provision of $6,600 in 1997 in
     connection with the termination of the Company's status as a Subchapter S
     corporation.  This one-time deferred income tax provision has been
     eliminated along with recording an income tax benefit of $3,874 resulting
     from the pro forma adjustments for acquisitions.

(i)  The Company operated as a Subchapter S corporation for income tax purposes
     until July 1, 1997. The pro forma income taxes represent taxes on the pro
     forma loss before income taxes and extraordinary charge after addback of
     all pro forma non-deductible expenses.

         SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED STATEMENTS OF
        OPERATIONS, OTHER DATA AND BALANCE SHEETS OF PIERCE LEAHY CORP.

The following summary historical and pro forma financial data of Pierce Leahy
Corp., insofar as it relates to each of the five years in the period ended
December 31, 1997, has been derived from the Company's audited consolidated
financial statements, including the consolidated balance sheets at December 31,
1996 and 1997, and the related consolidated statements of operations for each of
the three years in the period ended December 31, 1997 and the notes thereto
incorporated by reference into this Prospectus.  The summary historical and pro
forma consolidated statements of operations and balance sheet data as of and for
the six months ended June 30, 1998 and summary historical statement of
operations data for the six months ended June 30, 1997 have been derived from
unaudited consolidated financial statements incorporated by reference into this
Prospectus which, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results for the unaudited interim periods.  Results for the
six months ended June 30, 1998 are not necessarily indicative of results that
may be expected for the entire year.

The following summary pro forma statement of operations and other data give
effect to, among other things, acquisitions completed in 1997, the 1998
Acquisitions (all such 1997 acquisitions and the 1998 Acquisitions, the "1997
and 1998 Acquisitions") and the impact of the Offering, as if each of these
items had occurred on January 1, 1997.  The pro forma balance sheet gives effect
to the 1998 acquisitions which closed after June 30, 1998 (the "Recent
Acquisitions") as if the Recent Acquisitions had occurred on June 30, 1998.  In
1997, the Company recorded a deferred income tax provision of $6,600 (in
thousands) in connection with the termination of the Company's status as a
Subchapter S corporation for the tax effect of differences in the basis of
assets and liabilities for financial reporting and income tax purposes.  This
one-time deferred income tax provision has been eliminated in the Pro Forma
Condensed Consolidated Statement of Operations.  Also not reflected in the Pro
Forma Condensed Consolidated Statement of Operations is the extraordinary charge
of $6,036 (in thousands) for the early extinguishment of a portion of the 1996
Notes that occurred in August 1997.

The pro forma items and certain management assumptions and adjustments are
described in the accompanying notes hereto.  This pro forma information is not
necessarily indicative of the results that would have occurred had the 1997 and
1998 Acquisitions and the Offering been completed on the dates indicated or of
the Company's actual or future results or financial position.  The summary
historical and pro forma consolidated statements of operations, other data and
balance sheets should be read in conjunction with the information contained in
the Company's Consolidated Financial Statements and the notes thereto
incorporated by reference into this Prospectus and "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Selected Historical
and Pro Forma Consolidated Statements of Operations, Other Data and Balance
Sheets of Pierce Leahy Corp." and "Pro Forma Financial Data of Pierce Leahy
Corp." included elsewhere in this Prospectus.

           NOTES TO SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA

(n)  Gives effect to (i) the 1997 and the 1998 Acquisitions and (ii) the impact
     of the Offering, as if each of these items had occurred on January 1, 1997.
     See "Pro Forma Financial Data of Pierce Leahy Corp." and Note 2 of the
     Notes to Consolidated Financial Statements incorporated by reference
     herein.  In 1997, the Company recorded a deferred income tax provision of
     $6,600 in connection with the termination of the Company's status as a
     Subchapter S corporation for the tax effect of differences in the basis of
     assets and liabilities for financial reporting and income tax purposes.
     This one-time deferred income tax provision has been eliminated in the
     December 31, 1997 Pro Forma Condensed Consolidated Statement of Operations.
     Also not reflected in the December 31, 1997 Pro Forma Condensed
     Consolidated Statement of Operations is the extraordinary charge of $6,036
     for the early extinguishment of a portion of the 1996 Notes that occurred
     in August 1997.  See Note (f) below.

(o)  Upon consummation of Pierce Leahy's 1997 initial public offering, options
     granted during 1997 became fully vested and exercisable as provided for
     under the stock option plan.  The Company recorded a non-recurring, non-
     cash compensation charge of $1,752 relating to those options, representing
     the difference between the exercise price and the deemed value for
     accounting purposes.

(p)  Represents aggregate payments made to eight Pierce family members.

(q)  Represents non-recurring charge in 1996 of $2,764 paid to a related party
     partnership to assume the partnership's position in certain leases with
     third parties and of $490 for the establishment of an annual pension for
     Leo W. Pierce, Sr. and his spouse.

(r)  Until July 1, 1997, the Company was taxed as a Subchapter S corporation.
     Such status was terminated in connection with Pierce Leahy's 1997 initial
     public offering. See "Management's Discussion and Analysis of Financial
     Condition and Results of Operations" and Note 2 of Notes to Consolidated
     Financial Statements incorporated by reference herein.

(s)  Represents loss on early extinguishment of debt due to refinancings in
     1993, 1994, 1995, 1996 and 1997. Amounts include the write-off of
     unamortized deferred financing costs and discount, along with prepayment
     penalties and other costs. A charge for the early extinguishment of a
     portion of the 1996 Notes of $6,036 occurred in August 1997. Such charge
     has been eliminated in the Pro Forma Condensed Consolidated Statement of
     Operations. See  "Management's Discussion and Analysis of Financial
     Condition and Results of Operations."

(t)  Excluding $15,381 and $2,628 of operating expenses included in the pro
     forma statements of operations for 1997 and for the six months ended June
     30, 1998, respectively, specifically identified by management that would
     not have been incurred had the 1997 and 1998 Acquisitions occurred as of
     January 1, 1997 and had such cost savings been fully implemented as of such
     date, and excluding the special compensation charge incurred in 1997, pro
     forma net income (loss) and basic and diluted net income (loss) per share
     would have been $161 and $0.01, respectively, in 1997 and ($4,847) and
     ($0.28) for the six months ended June 30, 1998, respectively.

(u)  The earnings for the year ended December 31, 1997 and for the six months
     ended June 30, 1997 and 1998 were inadequate to cover fixed charges by
     $1,737, $39  and $4,529, respectively.

(v)  "EBITDA" is defined as net income (loss) before interest expense, taxes,
     depreciation and amortization, consulting payments to related parties, non-
     recurring charges with related parties, foreign currency exchange, special
     compensation charge and extraordinary charge. EBITDA is not a measure of
     performance under Generally Accepted Accounting Principles ("GAAP").
     Moreover, the use of EBITDA by the Company may not be comparable to
     similarly titled measures as reported by other companies.  While EBITDA
     should not be considered in isolation or as a substitute for net income,
     cash flows from operating activities and other income or cash flow
     statement data prepared in accordance with GAAP, or as a measure of
     profitability or liquidity, management understands that EBITDA is
     customarily used as a criteria in evaluating records management companies.
     However, substantially all of the Company's financing agreements, including
     the Notes and the 1996 Notes and the 1997 Notes (each as hereinafter
     defined), contain covenants in which EBITDA is used as a measure of
     financial performance. See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations" for a discussion of other
     measures of performance determined in accordance with GAAP and the
     Company's sources and applications of cash flows.

(w)  EBITDA, as adjusted is defined as EBITDA plus $15,381 and $2,628 of
     operating expenses included in the pro forma statements of operations for
     1997 and for the six months ended June 30, 1998, respectively, specifically
     identified by management that would not have been incurred had the 1997 and
     1998 Acquisitions occurred as of January 1, 1997 and such cost savings been
     fully implemented as of such date. See Note (b) of Notes to Pro Forma
     Condensed Consolidated Statements of Operations. Management expects to
     realize additional cost savings beyond the $15,381 and $2,628 specifically
     identified.

(x)  Capital expenditures for 1997 are comprised of $14.9 million for new
     shelving, $3.5 million for leasehold and building improvements, $10.6
     million for new facility purchases and related improvements, $3.7 million
     for data processing and $2.7 million for the purchase of transportation,
     warehouse and office equipment.

(y)  The pro forma cubic feet of storage as of June 30, 1998 includes cubic feet
     of storage from the Recent Acquisitions at the time of their respective
     acquisitions.

(z)  Gives effect to the Recent Acquisitions as if such acquisitions had
     occurred on June 30, 1998.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

GENERAL

  The Company is the largest hard copy records management company in North
America, as measured by its 78 million cubic feet of records currently under
management.  The Company's operations date to 1957 when its predecessor company,
L.W. Pierce Co., Inc., was founded to provide filing systems and related
equipment to companies in the Philadelphia area.  The Company expanded primarily
through internal growth until 1990, when it acquired Leahy Business Archives,
which effectively doubled its size.  Since 1992, the Company has pursued an
expansion strategy combining growth from new and existing customers with the
completion and successful integration of 43 acquisitions through 1997 and the
completion of 16 acquisitions to date in 1998.

  The Company's net income (loss) was $(15.2) million, $0.5 million, $2.1
million, $(5.5) million and $(0.04) million in 1997, 1996, and 1995 and the six
months ended June 30, 1998 and 1997, respectively.  Although the Company's
operating income has increased over the three years, net income (loss) has
fluctuated as a result of increases in foreign currency exchange, interest
expense, income taxes related to the termination of the Company's status as a
Subchapter S corporation, and extraordinary charges related to the early
extinguishment of debt due to refinancings in 1997, 1996 and 1995.

  Another tool for measuring the performance of records management companies is
"EBITDA" (net income (loss) before interest expense, taxes, depreciation and
amortization, consulting payments to related parties, non-recurring charges with
related parties, foreign currency exchange, special compensation charge and
extraordinary charge).  Substantially all of the Company's financing agreements,
including the Notes, the 1997 Notes and the 1996 Notes contain covenants in
which EBITDA is used as a measure of financial performance.  Moreover, the use
of EBITDA by the Company may not be comparable to similarly titled measures as
reported by other companies.  However, EBITDA should not be considered an
alternative to operating or net income (as determined in accordance with
generally accepted accounting principles ("GAAP")) as an indicator of the
Company's performance or to cash flow from operations (as determined in
accordance with GAAP) as a measure of liquidity.

(a) Net of permanent removals.  Includes effect of records destruction program
    of 475 and 372 cubic feet of records in 1996 and 1995, respectively, for a
    major customer, as recommended by the Company pursuant to a consulting
    agreement with the Company.

 Revenues

  The Company's revenues consist of storage revenues (58.8% of total revenues in
1997), and related service and storage material sales revenues (41.2% of total
revenues in 1997).  The Company provides records storage and related services
under annual or multi-year contracts that typically provide for recurring
monthly storage fees which continue until such records are permanently removed
(for which the Company charges a service fee) and service based on activity with
respect to such records.

  While the Company's total revenues have increased from 1995 to 1997, total
revenue per annual average cubic foot during such period has declined.  The
decline is principally attributable to (i) increases in sales to large volume
accounts under long-term contracts with discounted rates, which generate lower
revenue per cubic foot, but typically generate increased operating income, (ii)
renegotiation of contracts with existing customers to provide for longer term
contracts at lower rates, and (iii) competition.

  Operating Expenses and Productivity

  Operating expenses consist primarily of cost of sales, selling, general and
administrative expenses, and depreciation and amortization.  Cost of sales are
comprised mainly of wages and benefits, facility occupancy costs, equipment
costs and supplies.  The major components of selling, general and administrative
expenses are management, administrative, marketing and data processing wages and
benefits and also include travel, communication and data processing expenses,
professional fees and office expenses.

  The Company's depreciation and amortization charges result primarily from the
capital-intensive nature of its business and completed acquisitions.  The
principal components of depreciation relate to shelving, facilities and
leasehold improvements, equipment for new facilities and computer systems.
Amortization primarily relates to the amortization of intangible assets
associated with acquisitions, including goodwill, and the amortization of client
acquisition costs.  The Company has accounted for all of its acquisitions under
the purchase method except for two small acquisitions, which were accounted for
under the pooling of interests method.  Since the purchase price for records
management companies is usually substantially in excess of the fair market value
of their assets, these purchases have given rise to significant goodwill and,
accordingly, significant levels of amortization.  Although amortization is a
non-cash charge, it does impact reported net income (loss).

  Capital Expenditures and Client Acquisition Costs

  The majority of the Company's capital expenditures are related to expansion.
The largest single component is the purchase of shelving, which is directly
related to the addition of new records.  Shelving has a relatively long life and
rarely needs to be replaced.  Most of the Company's storage facilities (both in
number and square feet) are leased, but the Company will purchase facilities on
an opportunistic basis.  The Company's data processing capital expenditures are
also largely related to growth.

  The Company often incurs client acquisition costs, primarily sales commissions
and move-in costs.  Client acquisition costs are capitalized and amortized over
six years, which is the average initial contract term of new customer accounts.
In 1997, the Company incurred $10.6 million of client acquisition costs or
approximately $2.04 per cubic foot of client records moved in from new clients.
Amortization of client acquisition costs amounted to $3.2 million in 1997.

  Extraordinary Charge

  To provide capital to fund its growth oriented business strategy, the Company
has incurred substantial indebtedness.  The Company has completed several
refinancings and expansions of its credit facilities, primarily utilizing bank
debt and note issuances, which have resulted in one-time charges, including the
repurchase of warrants and the write-off of deferred financing costs, of $6.0
million, $2.0 million and $3.3 million in 1997, 1996 and 1995, respectively.

  Year 2000 Compliance

  The Company uses a number of computer software programs and systems in its
operations, including the PLUS/(R)/ system and embedded systems contained in the
Company's buildings, plant, equipment and other infrastructure.  The Company has
developed a plan designed to make its systems compliant with the requirements to
process transactions in the year 2000.  Review of the Company's core PLUS/(R)/
system databases and programs has been completed and code modifications and
testing are scheduled to be completed by December 31, 1998.  The present version
of the Company's internal financial accounting system is not year 2000 compliant
and is scheduled to be upgraded by December 31, 1998.  The Company is also
working with its other internal information systems and network providers to
ensure all systems are year 2000 compliant.  The Company estimates that the
expenses and capital expenditures associated with achieving year 2000 compliance
will approximate $350,000 of which approximately $250,000 had been expended as
of June 30, 1998. The Company estimates that its remediation costs incurred to
date in connection with the Year 2000 issue, including the replacement of non-
compliant systems, software modifications and validation, have been
approximately $250,000. In addition, the Company estimates the cost to complete
its Year 2000 evaluation, remediation and validation of all systems will
approximate an additional $100,000. Funding for costs incurred to date has come
from cash flows from operations, and future costs are expected to be funded in a
similar manner. The Company has not deferred any significant system projects due
to its Year 2000 efforts.

Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997

     Total revenues increased from $86.4 million for the six months ended June
30, 1997 to $120.4 million for the six months ended June 30, 1998, an increase
of $34.0 million, or 39.3%. Twenty-eight acquisitions were completed from
January 1997 to June 1998, which accounted for $24.4 million, or 71.8%, of such
increase in total revenues. The balance of the revenue growth resulted from
sales to new customers and from net increases in cubic feet stored from existing
and acquired customers.

     Storage revenues increased from $50.0 million for the six months ended June
30, 1997 to $70.4 million for the six months ended June 30, 1998, an increase of
$20.4 million, or 40.8%.  Service and storage material sales revenues increased
from $36.4 million for the six months ended June 30, 1997 to $50.0 million for
the six months ended June 30, 1998, an increase of  $13.6 million, or 37.4%.

     Cost of sales (excluding depreciation and amortization) increased from
$47.9 million in the six months ended June 30, 1997 to $69.2 million in the six
months ended June 30, 1998, an increase of $21.3 million, or 44.4%, and
increased as a percentage of total revenues from 55.5% in the 1997 period to
57.5% in the 1998 period. The increase in dollars and as a percentage of total
revenues resulted primarily from an increase in wages and benefits resulting
from an increased number of employees and an increase in facility occupancy
costs resulting from an increase in cubic feet stored from growth and
acquisitions.

     Selling, general and administrative expenses increased from $14.2 million
for the six months ended June 30, 1997 to $17.6 million for the six months ended
June 30, 1998, an increase of $3.4 million, or 24.4%, but decreased as a
percentage of total revenues from 16.4% in the 1997 period to 14.6% in the 1998
period. The dollar increase was primarily attributable to increases in staffing,
including increases in sales force and administrative staff. The decrease as a
percentage of total revenues was attributable to economies realized from the
administrative efficiencies of operating in a centralized manner including the
use of the Company's proprietary PLUS(R) computer software system.

     Depreciation and amortization expense increased from $9.4 million for the
six months ended June 30, 1997 to $15.8 million for the six months ended June
30, 1998, an increase of $6.4 million, or 67.6%, and increased as a percentage
of revenues from 10.9% for the six months ended June 30, 1997 to 13.1% for the
six months ended June 30, 1998. The increase in both dollars and percentage of
total revenues was primarily attributable to the additional depreciation and
amortization expense related to the 28 acquisitions completed from January 1997
to June 1998 and to capital expenditures for buildings, shelving, improvements
to records management facilities and information systems, and client acquisition
costs.

     The Company had a foreign currency exchange loss for the six months ended
June 30, 1997 of $0.1 million (0.1% of total revenues) and a loss of $3.7
million (3% of total revenues) for the six months ended June 30, 1998. The
change in the foreign currency exchange is primarily due to a decrease in the
value of the Canadian dollar compared to the U.S. dollar. This movement affects
liabilities denominated in U.S. dollars, primarily the $135.0 million principal
amount of 8/1/8/% Senior Notes issued by Command.

     Interest expense increased from $14.9 million for the six months ended June
30, 1997 to $18.7 million for the six months ended June 30, 1998, an increase of
$3.8 million, or 25.8%.  The increase was primarily attributable to increased
indebtedness incurred to finance acquisitions and capital expenditures.

                                      -50-

     As a result of the foregoing factors, the Company had a loss before income
taxes of $.04 million  for the six months ended June 30, 1997 compared to a loss
before income taxes of $4.5 million  for the six months ended June 30, 1998.

     The Company recorded a provision for income taxes of $1.0 million (0.8% of
total revenues) for the six months ended June 30, 1998. There were no income
taxes in the six months ended June 30, 1997 since the Company operated as a
Subchapter S corporation during such period.

     As a result of the foregoing items, net loss for the six months ended June
30, 1997 was $0.04 million and the net loss was $5.5 million (4.6% of total
revenues) for the six months ended June 30, 1998.

     EBITDA increased from $24.4 million for the six months ended June 30, 1997
to $33.6 million for the six months ended June 30, 1998, an increase of $9.2
million, or 38.0%. As a percentage of total revenues, EBITDA was 28.1% for the
six months ended June 30, 1997 and 27.9% for the six months ended June 30, 1998.

     Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     Total revenues increased from $129.7 million in 1996 to $183.5 million in
1997, an increase of $53.8 million or 41.4%. Revenues from acquisitions
represented $34.9 million of this increase.  Approximately $18.9 million of the
total revenue growth resulted from sales to new customers and increases in cubic
feet stored from existing customers, a base business revenue growth of
approximately 16% year over year.

     Storage revenues increased from $75.9 million in 1996 to $107.9 million in
1997, an increase of $32.0 million or 42.1%.  Service and storage material sales
revenues increased from $53.8 million in 1996 to $75.6 million in 1997, an
increase of $21.8 million or 40.5%.

     Cost of sales (excluding depreciation and amortization) increased from
$73.9 million in 1996 to $101.9 million in 1997, an increase of $28.1 million or
38.0%, but decreased slightly as a percentage of total revenues from 57.0% in
1996 to 55.5% in 1997. The $28.1 million increase was due primarily to increases
in wages and benefits resulting from an increased number of employees and to
increases in facility occupancy costs resulting from an increase in cubic feet
associated with the growth in business and entry into 14 new markets during
1997. Capacity utilization is generally lower in new markets than in existing
markets. The decrease as a percentage of total revenue was due primarily to
increased labor operating efficiencies.

     Selling, general and administrative expenses increased from $20.0 million
in 1996 to $30.1 million in 1997, an increase of $10.1 million or 50.3%, and
increased as a percentage of total revenues from 15.4% in 1996 to 16.4% in 1997.
The increase as a percentage of total revenues was due to increases in sales
personnel and training costs associated with the increased staff, enhancements
to the PLUS(R) system, and temporarily carrying duplicate administrative costs
from recent acquisitions.

     A special compensation charge of $1.8 million was incurred during 1997.
This charge relates to the write-off of the unamortized compensation expense due
to the acceleration of the vesting of the stock options granted on January 1,
1997 in conjunction with the Company's initial public offering of Common Stock.

     Depreciation and amortization expenses increased from $12.9 million in 1996
to $21.5 million in 1997, an increase of $8.7 million or 67.3%, and increased as
a percentage of total revenues from 9.9% in 1996 to 11.7% in 1997. This increase
was the result of increased capital expenditures for shelving, building, and
improvements to records management facilities and information systems and the
amortization of goodwill from the Company's acquisitions and client acquisition
costs.

     The Company incurred a foreign currency exchange adjustment in 1997 of $0.7
million during which time the Company had an intercompany loan with the Issuer.
This exchange adjustment was directly related to the decrease in the Canadian
dollar to U.S. dollar exchange rate during the last quarter of 1997.

     The Company incurred non-recurring charges of $3.3 million, or 2.5% of
total revenues, in 1996 in connection with the assumption of leasehold interests
in certain facilities from affiliated parties completed in connection with the
sale of the 1996 Notes and with the establishment of a pension for Leo W.
Pierce, Sr.

     Interest expense increased from $17.2 million in 1996 to $29.3 million in
1997, an increase of $12.0 million or 69.9%.  The increase was primarily
attributable to increased indebtedness related to financing acquisitions and
capital expenditures, as well as the higher interest rate on the 1997 Notes
issued in July 1997 and a full year of interest expense on the 1996 Notes
compared to the bank debt repaid upon the issuance of the 1997 Notes and 1996
Notes. Interest expense was also affected by the proceeds of the Company's
initial public stock offering.

                                      -51-

     As a result of the foregoing factors, the Company had a loss before income
taxes and extraordinary charge of $1.7 million (0.9% of revenues) for 1997
compared to income of $2.5 million (1.9% of revenues) in 1996.

     The Company recorded a provision for income taxes of $7.4 million (or 4.1%
of revenues) for 1997. These taxes were comprised of the tax effect from the
termination of the Company's Subchapter S status ($6.6 million) and the
provision for the results of operations after the termination of its status as
an S Corporation on July 1, 1997 ($0.8 million). There was no provision for
income taxes in the year ended 1996 since the Company operated as a Subchapter S
corporation during the period.

     The Company recorded extraordinary charges of $6.0 million in 1997 and $2.0
million in 1996 related to the early extinguishment of debt as a result of
refinancing and expanding its existing credit agreement in 1997 and 1996.

     As a result of the foregoing items, the Company had a net loss of $15.2
million and net income of $0.5 million for 1997 and 1996, respectively.

     EBITDA increased from $35.9 million in 1996 to $51.5 million in 1997, an
increase of $15.6 million or 43.6%, and increased as a percentage of total
revenues from 27.6% in 1996 to 28.1% in 1997.  The increase as a percentage of
the total revenues reflected growth in the Company's business, economies of
scale and increased operating efficiencies.

     Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     Total revenues increased from $95.4 million in 1995 to $129.7 million in
1996, an increase of $34.4 million or 36.0%. Revenues from acquisitions
represented $25.7 million or 74.9% of this increase, including $16.3 million
from a full year of operations of five acquisitions made in 1995 and $9.4
million from a partial year of operations of twelve acquisitions made in 1996.
Approximately $8.6 million or 25.1% of the total revenue growth resulted from
sales to new customers and increases in cubic feet stored from existing
customers.

     Storage revenues increased from $55.5 million in 1995 to $75.9 million in
1996, an increase of $20.4 million or 36.8%.  Service and storage material sales
revenues increased from $39.9 million in 1995 to $53.8 million in 1996, an
increase of $14.0 million or 35.0%.

     Cost of sales (excluding depreciation and amortization) increased from
$55.6 million in 1995 to $73.9 million in 1996, an increase of $18.3 million or
32.8%, but decreased as a percentage of total revenues from 58.3% in 1995 to
57.0% in 1996. The $18.3 million increase was due primarily to increases in
wages and benefits resulting from an increased number of employees and increases
in facility occupancy costs associated with the growth in business. The decrease
as a percentage of total revenue was due primarily to increased operating and
storage efficiencies.

     Selling, general and administrative expenses increased from $16.1 million
in 1995 to $20.0 million in 1996, an increase of $3.9 million or 23.9%, and
decreased as a percentage of total revenues from 16.9% in 1995 to 15.4% in 1996.
The decrease as a percentage of total revenues was due to operating efficiencies
and the implementation of programs to control and reduce certain administrative
expenses. The purchase of certain real estate interests from affiliates in
August 1996 contributed $0.9 million to the reduction in cost of sales or 0.7%
as a percentage of total revenues.

     Depreciation and amortization expenses increased from $8.2 million in 1995
to $12.9 million in 1996, an increase of $4.7 million or 57.7%, and increased as
a percentage of total revenues from 8.6% in 1995 to 9.9% in 1996. This increase
was the result of increased capital expenditures for shelving and improvements
to record management facilities and information systems and the amortization of
goodwill from the Company's acquisitions.

     The Company incurred non-recurring charges of $3.3 million in 1996 in
connection with the assumption of leasehold interests in certain facilities from
affiliated parties and with the establishment of a pension for Leo W. Pierce,
Sr.

     As a result of the foregoing factors, excluding the non-recurring charges
in 1996, operating income increased from $15.0 million in 1995 to $23.0 million
in 1996, an increase of 53.7% and increased as a percentage of total revenues
from 15.7% in 1995 to 17.7% in 1996. The increase reflected the growth in the
Company's business, economies of scale and increased operating efficiencies.

                                      -52-
<PAGE>
 
     Interest expense increased from $9.6 million in 1995 to $17.2 million in
1996, an increase of $7.6 million or 79.0%, due primarily to higher levels of
indebtedness. The Company recorded extraordinary charges of $2.0 million in 1996
and $3.3 million in 1995 related to the early extinguishment of debt as a result
of refinancing and expanding its existing credit agreement in 1996 and 1995.

     As a result of the foregoing factors, net income was $0.5 million in 1996
compared to net income of $2.1 million in 1995.

     EBITDA increased from $23.6 million in 1995 to $35.9 million in 1996, an
increase of $12.3 million or 51.8%, and increased as a percentage of total
revenues from 24.8% in 1995 to 27.7% in 1996.  The increase as a percentage of
the total revenues reflected growth in the Company's business, economies of
scale and increased operating efficiencies.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's primary sources of capital have been cash flows from
operations and borrowings under various revolving credit facilities and other
senior indebtedness. Historically, the Company's primary uses of capital have
been for acquisitions, capital expenditures and client acquisition costs.

     Capital Investments

     For 1997, 1996 and 1995, and the six months ended June 30, 1998, capital
expenditures were $35.4 million, $23.5 million, $16.3 million and $19.2 million,
respectively, and client acquisition costs were $10.6 million, $6.5 million,
$2.2 million and $4.4 million, respectively.  In 1998, the Company expects its
aggregate capital expenditures will approximate $35.0 million.  Over 85% of 1998
capital expenditures are anticipated to be growth related, primarily shelving
for new client records.

     Acquisitions

     In order to take advantage of the operating efficiencies of the PLUS(R)
system and the opportunities presented by the consolidation undergoing in the
record management industry, the Company has actively pursued acquisitions since
the beginning of 1994, which has significantly impacted liquidity and capital
resources. In 1997, the Company completed 17 acquisitions for an aggregate
purchase price of $109.1 million, consisting of $102.1 million in cash, 328,621
shares of Common Stock with a deemed value of $4.5 million and $1.7 million in
Sellers notes. Since the beginning of 1998, the Company has completed 16
acquisitions, for an aggregate cash purchase price of approximately $203.7
million and 548,262 shares of Common Stock with a deemed value of approximately
$14.4 million. The Company has historically financed its acquisitions with
borrowings under its credit agreements and notes and with cash flows from
existing operating activities.

     To the extent that future acquisitions are financed by additional
borrowings under the Company's credit facility or other types of indebtedness,
the resulting increase in debt and interest expense could have a negative effect
on such measures of liquidity as debt to equity.

     Sources of Funds

     Net cash flows provided by operating activities were $21.0 million, $26.4
million, $17.5 million and $15.2 million for 1997, 1996, 1995 and the six months
ended June 30, 1998, respectively.  The $5.5 million decrease from 1996 to 1997
was primarily comprised of a reduction in net income of $15.7 million and a
$14.1 million increase in working capital, offset by a $9.2 million increase in
depreciation and amortization, an increase in deferred income taxes of $7.4
million, a $4.0 million increase in extraordinary charge and a special
compensation charge of $1.8 million in 1997.

     Net cash flows used in investing activities were $156.5 million, $108.8
million, $51.3 million and $167.7 million for 1997, 1996, 1995 and the six
months ended June 30, 1998, respectively.  The uses of such cash flows were
primarily for acquisitions, capital expenditures and client acquisition
expenditures detailed above.

     Net cash flows provided by financing activities were $136.1 million, $82.9
million, $34.2 million and $153.3 million for 1997, 1996, 1995 and the six
months ended June 30, 1998, respectively.  In 1997, the $136.1 million in
financing activities consisted primarily of $120 million of gross proceeds from
the issuance of the 1997 Notes, $93.6 million in net proceeds from Pierce
Leahy's initial public offering of Common Stock, and $17.2 million of borrowings
on the revolving line of credit, offset by the repayment of long-term debt of
$82.5 million, the $7.0 million prepayment premium on the redemption of a
portion of the 1996 Notes and the payment of $5.2 million of financing costs
related to the issuance of the 1997 Notes and the Company's credit facility. In
August 1997, the Company entered into its current Credit Facility, which, as
amended, provides $150 million in U.S. dollar borrowings, and Cdn. $40 million
in Canadian dollar borrowings. In July 1996, the Company issued $200 million of
the 1996 Notes and used the net proceeds to retire all of the debt outstanding
under the Company's previous credit facility, to purchase certain properties
from affiliates of the Company, to redeem stock from a shareholder of the
Company, to fund an acquisition and for general corporate purposes.

                                      -53-
<PAGE>
 
     In April 1998, the Company issued $135.0 million principal amount of
Original Notes pursuant to the Purchase Agreement. Pursuant to the Exchange
Offer, the Exchange Notes will be substituted for those Original Notes which are
validly tendered and not withdrawn as provided herein.

     The Credit Facility contains a number of financial and other covenants
restricting the Company's ability to incur additional indebtedness and make
certain types of expenditures.  Covenants in the indentures governing the Notes,
the 1997 Notes and the 1996 Notes, also restrict borrowings under the Credit
Facility.  As of June 30, 1998, $44.0 million was outstanding under the Credit
Facility and the Company could have borrowed an additional $37.2 million in
accordance with the debt incurrence limitations.  The effective interest rate on
the Credit Facility, as of June 30, 1998, was approximately 7.71%.  As of June
30, 1998, on a pro forma basis, after giving effect to the Recent Acquisitions,
the Company could have borrowed an additional $30.2 million in accordance with
debt incurrence limitations.  Additionally, to the extent the Company makes
acquisitions, it would have additional availability under the Credit Facility
based upon the pro forma EBITDA of such acquisitions.

     Future Capital Needs

     Management believes that cash flow from operations in conjunction with
borrowings under the Credit Facility and possible other sources of financing
will be sufficient for the foreseeable future to meet working capital
requirements, debt service requirements and to make possible future acquisitions
and capital expenditures.  Depending on the pace and size of future possible
acquisitions, the Company may elect to seek additional debt or equity financing.
There can be no assurance that the Company will be able to obtain any future
financing, if required, or that the terms for any such future financing would be
favorable to the Company.

                                   BUSINESS

GENERAL

     Pierce Leahy Command Company is the issuer of the Notes and is an indirect
subsidiary of Pierce Leahy, which is a guarantor of the Notes on an unsecured
senior subordinated basis.  After consummation of the Archivex Acquisition, the
Issuer operates 26 records management facilities in the nine largest markets in
Canada.

     The Company is the largest hard copy records management company in North
America, as measured by its 76 million cubic feet of records currently under
management.  The Company operates a total of 222 records management facilities
of which 192 are in the United States, serving 69 markets, including 23 of the
25 largest U.S. markets.  In addition, the Company operates 30 records
management facilities in Canada's nine largest markets, including 26 facilities
operated by the Issuer and four facilities operated by Archivex.

     The Company's strategies and operations are intended to be standardized
throughout North America (United States and Canada).  Accordingly, unless
otherwise noted or the context otherwise suggests, the description of the
Company's strategies and operations are intended to cover all of its operations
in the United States and Canada.

     The Company is a full-service provider of records management and related
services, enabling customers to outsource their data and records management
functions.  The Company offers storage for all major media, including paper
(which has typically accounted for approximately 94% of the Company's storage
revenues), computer tapes, optical discs, microfilm, video tapes and X-rays.  In
addition, the Company provides next day or same day records retrieval and
delivery, allowing customers prompt access to all stored material.  The Company
also offers other data management services, including customer records
management programs, imaging services and records management consulting
services.

     The Company believes it is the most technologically advanced records
management company in the industry by virtue of its Pierce Leahy User
Solution(R) (PLUS(R)) computer system.  The PLUS(R) system fully integrates the
Company's records management, data retrieval and billing functions on a
centralized basis through the use of proprietary, real time software.  The
PLUS(R) system assists the Company in efficiently managing records in multiple
locations for national and local customers, rapidly integrating acquisitions of
records management companies and maintaining a low-cost operating structure. The
Company serves a diversified group of over 40,000 customer accounts in a variety
of industries such as financial services, manufacturing, transportation,
healthcare and law. The Company's storage and related services are typically
provided pursuant to contracts that include recurring monthly storage fees,
which continue until such records are permanently removed (for which the Company
charges a fee), and additional charges for services such as retrieval on a per
unit basis.

                                      -54-

     The Company's growth strategy is to expand its business in new and existing
markets through (i) targeting new customers, (ii) growing with existing
customers and (iii) continuing its acquisition program.  The Company has adopted
the following approaches to pursue its growth objectives:

     TARGETING NEW CUSTOMERS.   The Company has a dual sales strategy focused on
both larger, typically multi-location accounts and smaller accounts, with a
dedicated sales force for each.  The Company's sales and marketing force has
increased from approximately 70 persons at the end of 1996 to approximately 130
persons currently.

     GROWING WITH EXISTING CUSTOMERS. The Company services its existing
customers through both a centralized customer service organization and local
client service representatives. Existing customers typically generate additional
records annually which are stored with the Company.

     CONTINUING ACQUISITION PROGRAM.   The Company believes that the records
management industry is highly fragmented and offers substantial opportunity for
consolidation.  The Company targets potential acquisitions both in the markets
it already services and in new markets which it is not yet servicing.  From 1993
to 1997, the Company completed and integrated 39 acquisitions, totalling
approximately 22.3 million cubic feet of records at the time of acquisition.
Since the beginning of 1998, the Company has completed 16 acquisitions totaling
approximately 13.2 million cubic feet of records.

     The Company's growth strategy is supported by an operating strategy which
emphasizes providing premium standardized services while maintaining a low-cost
operating structure.  Both strategies apply to the entire North American market
(United States and Canada).  The Company expects to continue its growth and
enhance its position by implementing its strategy based on the following
elements:

          USING SOPHISTICATED CENTRALIZED SYSTEMS TO PROVIDE HIGH QUALITY
          SERVICE. In tandem with the Company's centralized customer service
          organization and local field support personnel, the Company utilizes
          its PLUS/(R)/ system to provide a high and consistent level of service
          (24 hours a day, seven days a week) to its customers on a national and
          local basis, including providing its customers with real-time access
          to the database. Although PLUS/(R)/ is centralized, the system permits
          local management flexibility through a variety of pre-programmed
          options to customize the system and enhance its utility to different
          types of customers.

          MAINTAINING ITS POSITION AS A LOW-COST PROVIDER THROUGH ECONOMIES OF
          SCALE. The Company strives to remain a low-cost operator through
          achieving economies of scale in labor, real estate, transportation,
          computer systems and administrative expenses. The PLUS/(R)/ system
          allows the Company to enhance the efficiency of its facilities while
          reducing fixed and operating costs. This system eliminates the need to
          designate permanent locations for an individual customer's records
          within a facility by using sophisticated bar-coding technology which
          enables records to be stored wherever space is available and to be
          positioned within the Company's facilities based on retrieval
          frequency, thereby reducing labor costs. PLUS/(R)/ is also valuable in
          helping to achieve cost savings in acquisitions.

THE RECORDS MANAGEMENT INDUSTRY

     According to a 1994 study by the Association of Commercial Record Centers
(the "ACRC"), an industry trade group with over 500 members, approximately 2,600
companies offer records storage and related services in North America. The
Company believes that only 25% of the potential market outsources its records
management functions and that approximately 75% is still "unvended," or
internally managed. The Company estimates that the North American vended records
management industry generates annual revenues in excess of $1.0 billion.
Management believes that the industry is highly fragmented, with most industry
participants operating on a regional or local basis.

     Saved documents, or records, generally fall into two categories: active and
inactive.  Active records refer to information that is frequently referenced and
usually stored on-site by the originator.  Inactive records are not needed for
frequent access, but must be retained for future reference, legal requirements
or regulatory compliance.

     Inactive records, which the Company estimates comprise approximately 80% of
all records, are the principal focus of the records management industry.

     The Company believes that the records management industry is characterized
by the following trends:

     INDUSTRY CONSOLIDATION.   The records management industry is undergoing a
period of consolidation as larger, better capitalized industry participants
acquire smaller regional or local participants.  Management believes that
consolidation is primarily driven by the needs of large customers for fully
integrated coverage and the ability to realize economies of scale, especially
with respect to labor, real estate, transportation and computer systems and
administrative expenses.  Industry consolidation also provides private owners of
smaller records management companies the ability to obtain liquidity.

     MOVEMENT TOWARDS OUTSOURCING.   Outsourcing of internal records management
functions represents the largest single source of new business for records
management companies.  The Company believes that as more organizations become
aware of the advantages of professional records management, such as net cost
reductions and enhanced levels of service, the records management industry will
continue to gain a growing portion of the unvended segment.  The Company also
believes that the establishment of national providers with well-known brand
names will help to accelerate this trend.

     INCREASING PRODUCTION OF PAPER. Increasingly widespread technologies such
as facsimiles, copiers, personal computers, laser printers and advanced software
packages have enabled organizations to create, copy and distribute documents
more easily and broadly. In spite of new "paperless" technologies (including the
Internet and "e-mail"), information remains predominantly paper based.
Additionally, the cost of storing records on paper is currently less expensive
than the cost of converting paper records to, and storing on, other media (e.g.,
computer media, imaging, microfilm, CD-Rom and optical disc).

     EXPANDED RECORD KEEPING NEEDS. While technology has augmented the growth of
paper generation, several external forces and concerns have played an important
role in organizations' decisions to store and retain access to records. For
example, the continued growth of regulatory requirements and the proliferation
of litigation has resulted in increased volumes and lengthened holding periods
of documents. Retained records are also remaining in storage for extended
periods of time because the process of determining which records to destroy is
time consuming and often more costly in the short-term than continued storage.

ACQUISITION HISTORY AND GROWTH STRATEGY

     The Company believes that the consolidation trend occurring in the North
American records management industry will continue and that acquisitions will
remain an important part of the Company's growth strategy.  Acquisitions provide
the Company with the ability to expand and achieve additional economies of
scale.  From 1993 to 1997, the Company successfully completed and integrated 39
acquisitions, totaling approximately 22.3 million cubic feet of records at the
time of acquisition.  Since January 1, 1998, the Company has completed 16
acquisitions, including the Archivex Acquisition and the Kestrel Acquisition,
totalling approximately 13.2 million cubic feet of records at the time of
acquisition.  As a result of its substantial acquisition experience, the Company
has developed a standardized program through which it integrates acquired
companies into its existing infrastructure.  In each of these acquisitions,
staffing levels were initially reduced with further reductions typically taking
place in the following months as general and administrative functions were
integrated into the Company's centralized operating system.

     The following table summarizes certain information for each acquisition
completed since 1993:

     The Company's centralized organizational structure and management
information systems are essential elements for both the successful integration
of acquired records management operations and the ability of the Company to
achieve economies of scale. The rapid conversion of an acquired company's
records into the PLUS(R) system and the integration of all corporate functions
(order processing, accounting, payroll, etc.) into the Company's corporate
organization in an efficient, standardized process allows the Company to realize
cost savings as a result of reduced labor and overhead costs and improved
facility utilization. The Company also believes that its centralized approach
permits better quality measurement and control procedures than a decentralized
approach to integrating acquisitions. See "Risk Factors-Risks Associated with
Acquisitions."

     The Company targets potential acquisitions both in locations it already
services (existing markets) and in new areas which it is not yet servicing.
Existing market acquisitions typically provide the highest degree of operating
leverage as a result of eliminating redundant overhead, such as overlapping
delivery runs, and when economically feasible, consolidating with an existing
Company facility in the same market.  New market acquisitions allow the Company
to both expand its business generally and enhance its ability to serve multi-
location customer accounts.  These acquisitions are typically either the result
of following an existing customer into a new location or are on a more
opportunistic basis when an attractive acquisition comes to the attention of the
Company.  Once in the new area, the Company seeks to obtain records from its
existing multi-location customers which may have operations in that area.
Additionally, operating in the new locations assists the Company's sales force
in more effectively targeting new customers in that area.

THE 1998 ACQUISITIONS

     Since January 1998, the Company has completed 16 acquisitions (the "1998
Acquisitions"), including the Archivex Acquisition and the Kestrel Acquisition.
Five of the 1998 Acquisitions, including the Kestrel Acquisition, were completed
after June 30, 1998 (the "Recent Acquisitions").  The aggregate consideration
for the 1998 Acquisitions was approximately $203.7 million in cash and shares of
Common Stock with a deemed value of approximately $14.4 million.  The locations
of the facilities acquired in the 1998 Acquisitions are set forth above under
the section "Acquisition History and Growth Strategy."  One of such 1998
Acquisitions, Comac, is a marketing literature storage and fulfillment company.

                                      -58-

THE ARCHIVEX ACQUISITION

     In April 1998, the Company purchased substantially all of the assets of
Archivex Inc., a Canadian records storage company with operations in six
Canadian cities, including three markets in which the Issuer previously had
operations (Montreal, Toronto and Calgary) and three markets in which the Issuer
did not have a presence (Quebec City, Winnipeg and Edmonton).  The aggregate
cash consideration for the Archivex Acquisition, which represented a significant
expansion in the Canadian market, was approximately $63.0 million.  Included in
the Archivex Acquisition were six owned records storage facilities with in
excess of an aggregate of 600,000 square feet of space and five leased records
storage facilities with approximately 100,000 square feet of space.  The
Archivex Acquisition added 4.0 million cubic feet of records under management.
The Issuer loaned approximately $20 million to Archivex, which purchased the
assets of Archivex Inc. located in Montreal.  The Issuer purchased the remaining
assets of Archivex Inc.  After the Archivex Acquisition, the Issuer operates 26
records management facilities in nine markets and Archivex operates four records
management facilities in Montreal.

THE KESTREL ACQUISITION

     On July 2, 1998, the Company purchased all of the capital stock of Kestrel
Holdings, Inc., a records storage company which, through its subsidiaries,
operates records storage facilities in Dallas and Houston.  Included as part of
the acquisition are four owned records storage facilities with an aggregate of
approximately 264,000 square feet of space and four leased records storage
facilities with an aggregate of approximately 350,000 square feet of space.  The
Kestrel Acquisition added approximately 2.5 million cubic feet of records under
management. The consideration for the Kestrel Acquisition was approximately $52
million and was financed through borrowings under the Credit Facility.

DESCRIPTION OF SERVICES

     The Company's records management services are focused on storage, retrieval
and data management of hard copy documents.

     Storage

     Storage revenues have averaged 58% of total revenues during the Company's
last five fiscal years. Nearly all of the Company's storage fees are derived
from hard copy storage. During 1997, the Company generated 94% of its storage
revenues from hard copy storage and 6% from vault storage for special items such
as computer tapes, X-rays, films or other valuable items. Storage charges
typically are billed monthly on a per cubic foot basis.

     The Company tracks all of its records stored in cartons, from initial pick-
up through permanent removal, with the use of its PLUS(R) system. Bar-coded
boxes are packed by the customer and transported by the Company's transportation
department to the appropriate facility where they are scanned and placed into
storage at the locations designated by PLUS(R). At such time, the Company's data
input personnel enter the data twice (i.e., double key verifying) to enhance the
integrity of the information entered into the system.

     The Company offers secure, climate-controlled facilities for the storage of
non-paper forms of media such as computer tapes, optical discs, microfilm, video
tapes and X-rays.  These types of media often require special facilities due to
the nature of the records.  The Company's storage fees for non-paper media are
higher than for typical paper storage.  The Company also provides ancillary
services for non-paper records in the same manner as it provides for its hard
copy storage operations.

     Service and Product Sales

     The Company's principal services include adding records to storage,
temporary removal of records from storage to support a customer's need to review
the files, replacing temporarily removed records and permanent withdrawals from
storage or destruction of records. Pick-up and delivery of customer records can
be tailored to a customer's specific needs and range from standard service
(typically requests received by 10:30 a.m. are delivered or picked up that
afternoon and requests received by 3:30 p.m. are delivered or picked up the next
day) to emergency service (typically within three hours or less). Pick-up and
delivery operations are supported by the Company's fleet of over 550 owned or
leased vehicles. The Company charges for pick-up and delivery services on a per-
unit basis depending on the immediacy of delivery requested.

                                      -59-
<PAGE>
 
     A small percentage of the Company's customers manage their records on a
file by file basis, allowing the customer direct access and traceability of a
specific file (rather than on a box by box basis). The Company provides data
entry services to such customers to input the file by file listings into the
PLUS(R) system.

     The Company also offers a records destruction service, which provides
customers with a secure, controlled program to periodically review and remove
records which no longer need to be retained.  Although boxes destroyed no longer
generate monthly storage fees, the Company charges for the destruction of
records and increases its available shelving space as a result.  The Company
believes its ability to manage destruction programs for customers efficiently
through the PLUS(R) system also enhances its ability to attract large accounts.

     In addition to providing traditional storage, customers may contract with
the Company to manage their on-site records or file services center. Such
management services generally include providing Company personnel to manage the
customer's active files (including records storage and tracking) at the
customer's facilities, supplemented by off-site storage at the Company's
facilities. As part of this service, the Company can use its own internally
developed file management software, or maintain the customer's existing system.
The Company also provides consulting and other services on an individualized
basis, including advisory work for customers setting up in-house records
management systems. In addition, the Company sells cardboard boxes and other
storage containers to its customers.

CUSTOMER SERVICE

     Customer calls are routed into one of the Company's two centralized
customer service departments located in the Company's U.S. and Canadian
corporate headquarters. Both customer service departments are staffed and can
receive customer calls 24 hours a day, seven days a week. The Company currently
employs approximately 86 customer service representatives. Routine pick-up and
delivery requests are dispatched directly by customer service representatives to
local facilities as directed by PLUS(R).

     PLUS(R), in tandem with a centralized order processing organization and
local field support personnel, enables the Company to provide a high and
consistent level of service (24 hours a day, seven days a week) to its customers
in a cost-effective manner. The centralized order entry system allows (i)
efficient workload balancing as the daily "peak" call-in periods can be spread
over three time zones, (ii) centralized quality control monitoring to increase
delivery of consistent and high-quality service, and (iii) the employment of
Spanish-speaking customer service representatives whose language skills can
serve any of the Company's U.S. customers, primarily for its operations in
Florida, Texas and California.

     As a complement to its centralized customer service departments, the
Company provides client service representatives to work with existing customers
at the local level. In addition to maintaining personal contacts with customers,
the local client service representatives help meet the Company's customers'
changing records management needs through advice in efficient recordkeeping
procedures, and, when appropriate, by offering the sale of additional services.

MANAGEMENT INFORMATION SYSTEMS

     The Company believes that PLUS(R), its core management information system,
is the most sophisticated records management system in the industry, and
provides the Company with a significant customer service and cost advantage in
attracting and retaining major accounts with records storage needs in multiple
locations and acquiring other records management companies. The Company's
centralized customer service and billing functions eliminate the need for
redundant functions at individual facilities. In addition, the PLUS(R) system
enables the Company to offer its customers full life cycle records management,
from file creation to destruction, and coordinates inventory control, order
entry, billing, material sales, service activity, accounts receivable and
management reporting on a centralized basis. PLUS(R) utilizes database
technology, proprietary software and extensive bar coding in a flexible,
enterprise-wide, client/server environment.

     Implementation of the PLUS(R) system has improved the Company's operating
efficiency by streamlining a number of its daily work processes:

 .    PLUS(R) allows the Company real time access to locate each unit of a
     customer's records, regardless of geographic location, through an
     enterprise-wide, shared database and to centrally receive and dispatch 
     pick-up and delivery orders to the appropriate location for processing.
     Management believes that no other records management system in the industry
     offers such real time access for multiple locations.

 .    The PLUS(R) system reduces the number of employees required to handle the
     inbound/outbound movement of boxes through the use of sophisticated
     algorithms which allow archive employees to process multiple customer
     requests in an efficient manner.

 .    PLUS(R) facilitates the integration of acquired records management
     companies in an efficient, standardized process. By converting the acquired
     company's records into the PLUS(R) system, the Company is able to reduce
     the labor and overhead costs associated with the acquisition, resulting in
     cost savings.

 .    The PLUS(R) system assists the Company in efficiently utilizing its storage
     space by eliminating the need for permanent locations for individual
     records. At any one time, approximately 2% of total cubic feet of records
     managed by the Company are temporarily returned to customers, freeing up
     storage space which PLUS(R) enables the Company to use productively. When a
     box is temporarily returned to a customer, a new box may be placed in the
     original box's location. Upon return of the original box to the Company,
     PLUS(R) automatically assigns the box a new location within a facility in
     the market in which the Company determines to store the box.

     PLUS(R) offers several additional features which enhance the Company's
customer support functions.  The PLUS(R) system is continuously updated when any
account activity is undertaken, providing customers with real time access to
information regarding box location and retrievals.  The PLUS(R) system is
flexible and allows the Company to design and implement customized records
management solutions for various industries utilizing a set of standardized
options.  The PLUS(R) system's on-line customer support network allows certain
customers to place orders for both records storage and retrieval directly from
their own in-house terminals resulting in a more efficient system of records
management.  PLUS(R) can also perform sophisticated searches to locate inventory
items even when the customers do not have the specific number of the box they
are seeking.  In addition, the Company has recently initiated a trial program,
PLUS(R) Link, which is designed to transfer information directly between the
Company's centralized database and a customer's local file room.

SALES AND MARKETING

     During the past five years, the Company has invested significant effort in
developing its sales and marketing department, which is comprised of
approximately 130 employees in the United States and Canada.  Sales
representatives are trained to sell a "total systems approach," in which a
customer's records management requirements are surveyed and evaluated in order
to determine the file management system which best meets the customer's needs
and offer recommendations on how to implement such a system. From 1993 to 1997,
the Company's sales representatives secured over 4,000 new customer accounts
comprising over 12.8 million cubic feet of records from new accounts.

     The Company's sales and marketing department is divided into five regions:
Northeast; South; Midwest; West; and Canada.  The Company's Vice President,
Sales and Marketing directs five regional sales managers who are each
responsible for one of the regions.  In addition, the Company's sales force is
divided between sales representatives who focus on large accounts which are
frequently multi-location and a recently expanded group of sales representatives
who focus on smaller, single-location customers.  The sales force is primarily
compensated on a commission basis with incentives tied to the Company's sales
goals.  The Company also uses telemarketing, direct response and print
advertising to assist in its marketing programs.

CUSTOMERS

     The Company serves a diversified group of over 40,000 customer accounts in
a variety of industries, including financial services, manufacturing,
transportation, healthcare and law. The Company tracks customer accounts, which
are based on invoices. Accordingly, depending on how invoices have been arranged
at the request of a customer, one customer may have multiple customer accounts.
None of the Company's customers accounted for more than 3% of the Company's
total revenues during any of the last three years. The Company services all
types of customers from small to medium size companies (such as professional
groups and law firms that often have one location) to Fortune 500 companies that
have operations in multiple locations. The Company provides records management
services to approximately one-half of the Fortune 500 companies and has over 50
customers with over 100,000 cubic feet of records under management with the
Company. Larger companies with multiple locations that have performed their own
records management services to date are a principal focus for new customers by
the Company. The Company believes that its presence in multiple locations in
conjunction with the PLUS(R) system enable it to provide the sophisticated file
management services frequently required by such customers.

     The Company's contracts with larger, typically multi-location customers
usually provide for an initial term of five or more years, and contracts with
other customers typically provide for initial terms of one or two years.  Both
types of contracts generally provide for annual renewals thereafter (with either
party having the right to terminate the contract).  Customers are generally
charged monthly storage fees until their records are destroyed or permanently
removed, for which fees are charged.  In addition, services such as file
retrieval are separately charged.  During 1997, approximately 3% of cubic feet
of records under management by the Company were permanently removed (other than
as part of an organized records destruction program).  The Company believes this
relatively low attrition rate is due to a number of factors, including
satisfaction with the Company's services as well as the effort and expense of
transferring records to another service provider or back in-house.

FACILITIES

     The Company operates a total of 222 records management facilities of which
192 are in the United States, serving 67 markets, including 23 out of 25 of the
largest U.S. markets, and 30 facilities in Canada serving Canada's nine largest
markets. Of the 15.9 million square feet of floor space (representing
approximately 107.9 million cubic feet of storage capacity) in the Company's
records storage facilities, approximately 36% and 64% (40% and 60% on a cubic
footage basis) are in owned and leased facilities, respectively. The Company's
facilities are located as follows:

</TABLE>

  In response to certain opportunities that arose, the Company has made
significant new facility investments, substantially increasing the Company's
available storage capacity in its Northeast region.  During 1995, the Company
purchased a storage facility in New Jersey with 12 million cubic feet of storage
capacity and leased (with an option to purchase) a storage facility in
Massachusetts with five million cubic feet of storage capacity.  The Company is
in the process of consolidating certain individual warehouses into these
facilities and will consolidate other warehouses over the next two or three
years as existing leases expire.  The addition of these facilities provides the
Company with substantial excess storage capacity in such region and is expected
to satisfy the Company's facility expansion requirements in its Northeast region
for several years.  The Company intends to consolidate facilities in other
locations when appropriate.  Primarily as a result of the new facilities in New
Jersey and Massachusetts, warehouse utilization has declined to approximately
70% from historical levels to 80%.

COMPETITION

  The Company competes with numerous records management companies in all
geographic areas in which it operates. The Company believes that competition for
customers is based on price, reputation for reliability, quality of service and
scope and scale of technology, and believes that it generally competes
effectively based on these factors. Management believes that, except for Iron
Mountain Incorporated, all of these competitors have records management revenues
significantly lower than those of the Company. The Company believes that the
trend towards consolidation in the industry will

                                      -63-
<PAGE>
 
continue, and the Company also faces competition in identifying attractive
acquisition candidates. In addition, the Company faces competition from the
internal document handling capability of its current and potential customers.

  The substantial majority of the Company's revenues are derived from the
storage of paper records and from related services.  Alternative technologies
for generating, capturing, managing, transmitting and storing information have
been developed, many of which require significantly less space than paper.  Such
technologies include computer media, microforms, audio/video tape, film, CD-Rom
and optical disc.  Management believes that conversion of paper documents into
these smaller storage media is currently not cost-effective for inactive
records, primarily due to the high labor cost of preparing and converting the
documents for imaging.

EMPLOYEES

  As of July 31, 1998, the Company had 3,163 employees (296 part-time employees
and 2,867 full-time employees), including 617 employees in Canada.
Approximately 50 of the employees of Archivex in Canada are covered by a
collective bargaining agreement.  Management considers its employee relations to
be good.

INSURANCE

  The Company carries comprehensive property insurance covering replacement
costs of real and personal property.  Subject to certain limitations and
deductibles, such policies also cover extraordinary expenses associated with
business interruption and damage or loss from fire, flood or earthquakes (in
certain geographic areas), and losses at the Company's facilities for
approximately $500 million.

ENVIRONMENTAL MATTERS

  The Company's properties and operations, past or present, may be subject to
liability under various environmental laws, regardless of fault, for the
investigation, removal or remediation of soil or groundwater, on or off-site,
resulting from the release or threatened release of hazardous materials, as well
as damages to natural resources.  The past or present owner or operator of
contaminated property may also be subject to claims for damages and remediation
costs from third parties based upon the migration of any hazardous materials to
other properties.

  At certain of the properties owned or leased by the Company, petroleum
products or other hazardous materials are or were stored in USTs.  Some formerly
used USTs have been removed; others were abandoned in place.  The Company
believes all of the USTs are registered, where required under applicable law.
Some of the properties acquired in the Archivex Acquisition may contain USTs
which are required to be removed.  It is expected that removal costs to the
Issuer will not be material.  The Company also is aware of the presence in some
of its facilities of ACMs, but believes that no action is presently required to
be taken as a result of such material.

  At the Company's New Jersey facility, certain contamination has been
discovered resulting from operations of the prior owner thereof.  The prior
owner, which has agreed to be responsible for the cost of such remediation, is
completing remediation of the property under a consent order with the New Jersey
Department of Environmental Protection ("NJDEP").  The prior owner has posted a
$1.1 million letter of credit with the NJDEP.  The Company has purchased an
environmental liability insurance policy covering the cleanup costs to the
Company, if any, resulting from any on- or off-site environmental condition
existing at the time of the Company's acquisition of this property, with a
$500,000 deductible and policy limits of $4 million per occurrence/$8 million in
the aggregate, provided the claim first arises during the term of the policy,
which is August 11, 1998 through August 11, 2003.

  The Company has not received any written notice from any governmental
authority or third party asserting, and is not otherwise aware of, any material
noncompliance, liability or claim under environmental laws applicable to the
Company other than as described above. No assurance can be given that there are
no environmental conditions for which the Company may be liable in the future or
that future regulatory action, or compliance with future environmental laws,
will not require the Company to incur costs that could have a material adverse
effect on the Company's financial condition or results of operations.

LEGAL PROCEEDINGS

                                      -64-
<PAGE>
 
  The Company is involved in litigation from time to time in the ordinary course
of its business.  In the opinion of management, no material legal proceedings
are pending to which the Company, or any of its property, is subject.

______________
*    The options have no specified expiration date.
(1)  All options were granted under Pierce Leahy's Nonqualified Stock Option
     Plan (the "Plan"). The options were originally scheduled to vest in five
     equal annual installments commencing on the first anniversary of the date
     of grant. However, upon the completion of the initial public offering of
     Pierce Leahy's Common Stock on July 1, 1997, these options became fully
     vested and exercisable. Pierce Leahy may make loans with respect to vested
     options.
(2)  Illustrates the value that might be received upon exercise of options
     immediately prior to the assumed expiration of their term at the specified
     compounded rates of appreciation based on the market price for Pierce
     Leahy's Common Stock when the options were granted. There was no
     established trading market for Pierce Leahy's Common Stock at the time the
     options were issued, so the market price is based upon the formula set
     forth in the Plan based upon a multiple of EBITDA, as well as the amount of
     cash, cash equivalents, outstanding indebtedness and other obligations of
     Pierce Leahy. Since the options granted to the Named Executives do not have
     a specified expiration date, for purposes of calculating the assumed
     appreciation, the options have been deemed to expire ten years from the
     date of grant. Assumed rates of appreciation are not necessarily indicative
     of future stock performance.

(1) The value of unexercised in-the-money options is based on the difference
    between the last sale price of a share of Common Stock as reported by the
    New York Stock Exchange on December 31, 1997 ($20.50) and the exercise price
    of the options, multiplied by the number of options.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    Prior to Pierce Leahy's initial public offering of Common Stock in July
1997, the Compensation Committee of its Board of Directors was comprised of Leo
W. Pierce, Sr., J. Peter Pierce and Alan B. Campell. Leo W. Pierce, Sr. is the
former Chief Executive Officer and President of the Company and J. Peter Pierce
is the Company's Chief Executive Officer and President.

     The Company leases from four separate limited partnerships its corporate
headquarters in King of Prussia, Pennsylvania and its facilities in Suffield,
Connecticut, Orlando, Florida and Charlotte, North Carolina.  J. Peter Pierce,
the Company's President and Chief Executive Officer, is the general partner of
three of the limited partnerships and members of the Pierce family and certain
other officers and directors of the Company and their affiliates own substantial
limited partnership interests in each of the four limited partnerships.  The
lease on the Company's corporate headquarters expires on April 30, 2003, without
any renewal options.  The leases for the Suffield, Orlando and Charlotte
facilities terminate on December 31, 2005, October 31, 2004 and August 31, 2001,
respectively.  Each of such leases contains two five-year renewal options.  The
aggregate rental payments by the Company for such properties during 1995, 1996
and 1997 were $773,000, $894,000 and $961,000, respectively.

     In August 1996, the Company purchased for $14.9 million all of the
interests of the two partnerships owned by members of the Pierce family in six
facilities previously leased to the Company and 16 facilities previously
subleased, as well as minority interests in five other properties currently
leased by the Company. The purchase price was based on third party appraisals or
the recent acquisition price for the six facilities and management's estimates
of the value of the leasehold and minority ownership interests based on the net
present value of the cash flows generated by such interests. The leases and
subleases were entered into during the period from March 1980 to April 1995. The
aggregate rental payments for the leases and subleases were $8,201,000 and
$4,624,000 in 1995 and the portion of 1996 prior to the purchase, respectively.

     The Company believes that the terms of its leases with the related parties
are as favorable to the Company as those generally available from unaffiliated
third parties. There are no plans by the Company to lease additional facilities
from officers, directors or other affiliated parties.

  In December 1993, the Company's Chairman, Leo W. Pierce, Sr., advanced $80,000
to the Company.  The Company repaid the loan, together with interest at 7%, in
three equal installments in December 1994, December 1995 and May 1996.  In July,
1996, the Company redeemed 100 shares of voting Class A Common Stock (equivalent
to 105,910 shares of Common Stock after a stock recapitalization) from Mr.
Pierce for an aggregate price of $1.45 million, which price was based on the
Company's EBITDA.  The Company had previously undertaken to pay $60,000 per year
for a five-year period to Mr. Pierce's spouse upon his death.  The Company
replaced this arrangement by providing an annual pension in the amount of
$96,000 to Mr. Pierce and then to his spouse, if she survives him.

  The Company entered into a tax indemnification agreement with the shareholders
of the Company prior to its initial public offering of Common Stock which
provides for: (i) the distribution to such shareholders of cash equal to the
product of the Company's taxable income for the period from January 1, 1997
until the date the Company's initial public offering was completed and the sum
of the highest effective federal and state income tax rate applicable to any
current shareholder (or in the case of shareholders that are trusts, any
beneficiaries), less any prior distributions to such shareholders to pay taxes
for such period, and (ii) an indemnification of such shareholders for any losses
or liabilities with respect to any additional taxes (including interest,
penalties and legal fees) resulting from the Company's operations during the
period in which it was a Subchapter S corporation.

  Alan B. Campell was a managing director of Campell Vanderslice Furman ("CVF"),
an investment banking firm that provided investment banking services to the
Company from 1992 until its termination in 1997.  During 1995, 1996 and 1997,
the Company paid CVF $0.7 million, $0.8 million and $0.1 million, respectively,
with respect to investment banking services.  In 1997, CVF received a fee of
approximately $1.8 million in connection with the Company's initial public
offering of Common Stock and its concurrent offering of the 1997 Notes.  CVF is
expected to receive a fee of approximately $0.3 million in connection with the
Offering.  The Company believes that the fees paid to CVF were customary in the
industry for such services.

                              CERTAIN TRANSACTIONS

  In December 1994, the Company loaned $60,000 to J. Michael Gold, its Vice
President, Operations-Northeast.  During 1996 and 1997 additional amounts were
loaned to Mr. Gold.  The largest aggregate amount outstanding on the loan to Mr.
Gold was $215,657 and as of June 30, 1998, an aggregate of $15,773 was
outstanding.  Interest accrues on the loan at an annual rate of 8.875%

  In 1997, the Company paid $88,000 to Hayden Real Estate, Inc., a company owned
by J. Anthony Hayden, a Pierce Leahy director, for commissions on various real
estate transactions.

VOTING TRUST AGREEMENT

  In connection with Pierce Leahy's initial public offering in 1997, certain
members of the Pierce family, who own approximately 51% of the outstanding
shares of Common Stock, entered into a ten-year voting trust agreement (the
"Voting Trust Agreement") which appoints Leo W. Pierce, Sr. and J. Peter Pierce
as the Voting Trustees (the "Voting Trustees").  All shares subject to the
Voting Trust Agreement are voted at the direction of the Voting Trustees.  In
the event the Voting Trustees cannot agree on how to vote with respect to a
certain matter, one-half of the shares subject to the Voting Trust Agreement
will be voted according to the direction of each Voting Trustee.  In the event
that a Voting Trustee becomes unable or unwilling to continue serving as a
Voting Trustee, the remaining Voting Trustee will act as sole Voting Trustee.
The Voting Trust Agreement will terminate in the event both Trustees become
unable or unwilling to continue serving as Voting Trustees.  The Voting Trust
Agreement does not place any restriction on the transfer of shares held subject
to the Voting Trust Agreement; such shares will be released from the Voting
Trust Agreement upon their transfer to a person not subject to the Voting Trust
Agreement.  Some of the shares of Common Stock held by members of the Pierce
family that would otherwise be subject to the Voting Trust, are held by such
individuals subject to a proxy granting Leo W. Pierce, Sr. and J. Peter
Pierce the power to vote such shares (the "Proxies").  The Proxies, which are
intended to be the functional equivalent of the Voting Trust, are voted in the
same manner as shares held in the Voting Trust.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

THE 1996 NOTES

  In July 1996, Pierce Leahy issued $200,000,000 principal amount of 11 1/8%
Senior Subordinated Notes due 2006 (the "1996 Original Notes") pursuant to an
indenture dated as of July 16, 1996 between Pierce Leahy and United States Trust
Company of New York, as Trustee (the "1996 Indenture").  In November 1996,
Pierce Leahy exchanged the 1996 Original Notes for $200,000,000 principal amount
of 11 1/8% Senior Subordinated Notes due 2006 (the "1996 Notes"), which are
substantially identical to the 1996 Original Notes except that the 1996 Notes
are registered under the Securities Act.  The 1996 Notes mature on July 15, 2006
and bear interest at 11 1/8% per annum, payable semi-annually in arrears on
January 15 and July 15.  Pierce Leahy was entitled to redeem up to an aggregate
of $70,000,000 principal amount of the 1996 Notes at any time prior to July 15,
1999 with the net proceeds of the one or more Public Equity Offerings (as
defined in the 1996 Indenture) at a redemption price equal to 110% of the
aggregate principal amount so redeemed plus accrued interest to the redemption
date.  Pierce Leahy utilized a portion of the net proceeds of its initial public
offering of Common Stock to redeem $70,000,000 principal amount of the 1996
Notes.  Accordingly, $130,000,000 principal amount of the 1996 Notes currently
remains outstanding.

  The 1996 Notes are general unsecured obligations of Pierce Leahy, subordinated
in right of payment to Senior Indebtedness (as defined in the 1996 Indenture) of
Pierce Leahy and senior in right of payment to any current or future
subordinated indebtedness of Pierce Leahy, except as otherwise provided in the
1996 Indenture.  The Domestic Guarantors (other than Pierce Leahy) have
unconditionally guaranteed, on an unsecured senior subordinated basis, the
payment of principal, premium, if any, and interest, on the 1996 Notes jointly
and severally. Accordingly, the obligations of Pierce Leahy on the 1996 Notes
and the guarantees of the other Domestic Guarantors of the 1996 Notes rank pari
passu with their respective Domestic Guarantees.  The 1996 Notes are secured by
a pledge of 65% of the capital stock of the Issuer.  The pledge is on a second
priority basis, junior to the pledge of such shares in favor of the lenders and
the administrative agent under the Credit Facility and senior to the pledge in
favor of the holders of the 1997 Notes.  The 1996 Notes will be guaranteed, pari
passu with the Notes, on an unsecured senior subordinated basis, by any future
Domestic Guarantors.

  The 1996 Indenture contains, among other things, covenants restricting the
ability of Pierce Leahy and its subsidiaries to dispose of assets, pay stock and
indebtedness, create liens, make capital expenditures, make certain investments
or acquisitions, enter into transactions with affiliates and otherwise restrict
corporate activities.

THE 1997 NOTES

  In June 1997, Pierce Leahy issued $120,000,000 principal amount of 9 1/8%
Senior Subordinated Notes due 2007 (the "1997 Notes") pursuant to an indenture
dated as of July 7, 1997 ("1997 Indenture") between Pierce Leahy and The Bank of
New York, as Trustee.  The 1997 Notes mature on July 15, 2007 and bear interest
at 9 1/8% per annum, payable semi-annually in arrears on January 15 and July 15.
The 1997 Notes are general unsecured obligations of Pierce Leahy, subordinated
in right of payment to Senior Indebtedness (as defined in the 1997 Indenture) of
Pierce Leahy and senior in right of payment to any current or future
subordinated indebtedness of Pierce Leahy, except as otherwise provided in the
1997 Indenture.  The Domestic Guarantors (other than Pierce Leahy) have
unconditionally guaranteed, on an unsecured senior subordinated basis, the
payment of principal, premium, if any, and interest, on the 1997 Notes jointly
and severally.  Accordingly, the obligations of Pierce Leahy on the 1997 Notes
and the guarantees of the other Domestic Guarantors of the 1997 Notes rank pari
passu with the respective Domestic Guarantees.

  The 1997 Notes are secured by a pledge of 65% of the capital stock of the
Issuer.  The pledge is on a third priority basis, junior to the pledge of such
shares in favor of the lenders and the administrative agent under the Credit
Facility and to the pledge in favor of the holders of the 1996 Notes.

  The 1997 Indenture contains, among other things, covenants restricting the
ability of the Company and its subsidiaries to dispose of assets, pay dividends,
repurchase or redeem capital stock and indebtedness, create liens, make capital
expenditures, make certain investments or acquisitions, enter into transactions
with affiliates and otherwise restrict corporate activities.

                         DESCRIPTION OF CREDIT FACILITY

  In August 1997, Pierce Leahy and the Issuer entered into the Credit Facility
with Canadian Imperial Bank of Commerce ("CIBC" or "Agent") as the Agent, and
certain other lenders, providing for a senior secured revolving line of credit
in an aggregate principal amount of $140 million in U.S. 

                                      -75-
<PAGE>
 
dollar borrowings by Pierce Leahy and Cdn. $35 million in Canadian dollar
borrowings by the Issuer. The amount of U.S. dollar borrowings and Canadian
dollar borrowings provided for under the Credit Facility were subsequently
increased to U.S. $150 million and to Cdn. $40 million.

  The Credit Facility will mature on June 30, 2004, unless previously
terminated, and the aggregate available commitments under the Credit Facility
will be reduced incrementally on a quarterly basis, beginning March 31, 2001.

  Borrowings under the U.S. dollar portion of the Credit Facility bear interest
at a rate equal to, at the option of Pierce Leahy, either (i) the base rate
(which is based on the Federal Funds rate or the prime rate most recently
announced by the Agent) or (ii) LIBOR, in each case plus an applicable margin
determined by reference to the ratio of Total Net Debt to EBITDA of the Company
(as defined in the Credit Facility).  Borrowings under the Canadian dollar
portion of the Credit Facility also bear interest based on various methods plus
an applicable margin.

  The obligations of Pierce Leahy under the Credit Facility are unconditionally
guaranteed, jointly and severally, by all U.S. subsidiaries of the Company.  The
obligations of the Company and such guarantors under the Credit Facility are
secured primarily by a first priority pledge of the stock of all material U.S.
subsidiaries of Pierce Leahy, a first priority pledge of 65% of the capital
stock of the Issuer and a first priority lien on all of the assets of Pierce
Leahy, the Issuer and such guarantors.  Obligations under the Canadian facility
are guaranteed by Pierce Leahy.

  The Credit Facility contains, among other things, covenants restricting the
ability of the Company and its subsidiaries to dispose of assets, pay dividends,
repurchase or redeem capital stock and indebtedness, create liens, make capital
expenditures, make certain investments or acquisitions, enter into transactions
with affiliates and otherwise restrict corporate activities.  The Credit
Facility also contains a number of financial covenants.

                            DESCRIPTION OF THE NOTES

  The Original Notes were, and the Exchange Notes will be, issued under an
Indenture dated as of April 7, 1998 (the "Indenture") by and among the Issuer,
Pierce Leahy and The Bank of New York, as trustee (the "Trustee").  The terms of
the Notes include those stated in the Indenture and those made a part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act").  The Notes are subject to all such terms, and holders of
the Notes are referred to the Indenture and the Trust Indenture Act for a
statement of such terms.

  The following is a summary of the material terms and provisions of the Notes.
This summary does not purport to be a complete description of the Notes and is
subject to the detailed provisions of, and qualified by reference to, the Notes
and the Indenture (including the definitions contained therein).  Definitions
relating to certain capitalized terms are set forth under "Certain Definitions"
and throughout this description.  Capitalized terms that are used but not
otherwise defined herein have the meanings assigned to them in the Indenture,
and such definitions are incorporated herein by reference.  The Indenture has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part.   The form of the Exchange Notes and the Original Notes are identical
in all material respects except that the Exchange Notes will have been
registered under the Securities Act and, therefore, will not bear legends
restricting their transfer.  The Exchange Notes will not represent new
indebtedness of the Issuer, will be entitled to the benefits of the same
Indenture which governs the Original Notes and will rank pari passu with the
Original Notes.  Any provisions of the Indenture which require actions by or
approval of a specified percentage of Original Notes shall require the approval
of the holders of such percentage of principal amount of Original Notes and
Exchange Notes, in the aggregate.

GENERAL

  The Notes are limited in aggregate principal amount to $135,000,000.  The
Notes are general unsecured senior obligations of the Issuer, ranking pari passu
in right of payment to all existing and future senior indebtedness of the Issuer
and senior in right of payment to any current or future subordinated
indebtedness of the Issuer, except as otherwise provided herein.  The Notes will
not be secured by any assets and are effectively subordinated to any existing
and future secured indebtedness of the Issuer, including the Credit Facility.

  The Notes will be unconditionally guaranteed (the "Domestic Guarantees"), on a
senior subordinated basis, as to payment of principal, premium, if any, and
interest, jointly and severally, by Pierce Leahy, its two U.S. Subsidiaries,
Advanced Box, Inc. and Monarch Box, Inc., and by each future Restricted
Subsidiary of Pierce Leahy organized under the laws of the United States, any
state thereof or the District of Columbia (together with Pierce Leahy, the
"Domestic Guarantors").

  The Notes will be unconditionally guaranteed (the "Canadian Guarantees"), on a
senior basis, as to payment of principal, premium, if any, and interest, jointly
and severally, by Archivex and by each future Subsidiary of Pierce Leahy
organized under the laws of Canada or any province thereof, which is not
prohibited by the laws of Canada or of any province thereof from acting as a
guarantor of the Notes and which has either assets or shareholders' equity in
excess of $5,000 (each, a "Canadian Guarantor," and together with the Domestic
Guarantors, the "Guarantors").  The Canadian Guarantees will be effectively
subordinated to any existing and future secured indebtedness of the Canadian
Subsidiaries, including the Credit Facility.

MATURITY, INTEREST AND PRINCIPAL

  The Notes will mature on May 15, 2008.  The Notes will bear interest at a rate
of 8 1/8% per annum from the date of original issuance until maturity.  Interest
is payable semi-annually in arrears on May 15 and November 15 of each year,
commencing November 15, 1998, to holders of record of the Notes at the close of
business on the immediately preceding May 1 and November 1, respectively. The
interest rate on the Notes is subject to increase, and such Special Interest
will be payable on the payment dates set forth above, in certain circumstances,
if the Notes (or other securities substantially similar to the Notes) are not
registered with the Commission within the prescribed time periods.

  The interest rate on the Notes is subject to increase, and such Additional
Interest will be payable on the payment dates set forth above, in certain
circumstances, if the Notes (or other securities substantially similar to the
Notes) are not registered with the Commission within the prescribed time
periods.  Upon consummation of the Exchange Offer, such registration
requirements will have been met and no Additional Interest will be payable with
respect to the Notes, except as set forth below.  In the event that the Company
does not substitute Exchange Notes for all Original Notes validly tendered in
accordance with the terms of the Exchange Offer on or prior to 60 days after the
date of this Prospectus or the Registration Statement of which this Prospectus
forms a part ceases to be effective at any time prior to the consummation of the
Exchange Offer (either such event, a "Registration Default"), the sole remedy
available to holders of the Notes will be the immediate assessment of additional
interest ("Additional Interest") as follows:  the per 

                                      -77-
<PAGE>
 
annum interest rate on the Notes will increase by 50 basis points; and the per
annum interest rate will increase by an additional 25 basis points for each
subsequent 90-day period during which the Registration Default remains uncured,
up to a maximum additional interest rate of 200 basis points per annum in excess
of the interest rate on the cover of this Prospectus. All Additional Interest
will be payable to holders of the Notes in cash on the same original issue
payment dates as the Notes, commencing with the first such date occurring after
any such Additional Interest commences to accrue, until such Registration
Default is cured. After the date on which such Registration Default is cured,
the interest rate on the Notes will revert to the interest rate originally borne
by the Notes (as shown on the cover of this Prospectus).

  The summary herein of certain provisions of the Registration Rights Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Registration Rights
Agreement, which has been filed as an exhibit to the Registration Statement of
which this Prospectus forms a part, a copy of which will be available upon
request to the Company.

OPTIONAL REDEMPTION

  The Notes will be redeemable at the option of the Issuer, in whole or in part,
at any time on or after May 15, 2003 at the following redemption prices
(expressed as a percentage of principal amount), together, in each case, with
accrued and unpaid interest to the redemption date, if redeemed during the
twelve-month period beginning on May 15, of each year listed below:

<TABLE>
<CAPTION>
YEAR                                              PERCENTAGE
- ----                                              ----------
<S>                                               <C>
 2003..........................................   104.063%
 2004..........................................   102.708%
 2005..........................................   101.354%
 2006 and thereafter...........................   100.000% 
</TABLE>

  Notwithstanding the foregoing, the Issuer may redeem in the aggregate up to
35% of the original principal amount of Notes at any time and from time to time
prior to May 15, 2001 at a redemption price equal to 108 1/8% of the aggregate
principal amount so redeemed, plus accrued interest to the redemption date out
of the Net Proceeds of one or more Public Equity Offerings; provided, that at
least 65% of the aggregate principal amount of Notes originally issued remains
outstanding immediately after the occurrence of any such redemption and that any
such redemption occurs within 90 days following the closing of any such Public
Equity Offering.

  In the event of redemption of fewer than all of the Notes, the Trustee shall
select either on a pro rata basis or by lot or in such other manner as it shall
deem fair and appropriate the Notes to be redeemed.  The Notes will be
redeemable in whole or in part upon not less than 30 nor more than 60 days'
prior written notice, mailed by first class mail to a holder's last address as
it shall appear on the register maintained by the Registrar of the Notes. If any
Note is to be redeemed in part only, the notice of redemption that relates to
such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note, in a principal amount equal to the unredeemed portion
thereof, will be issued in the name of the holder thereof upon cancellation of
the original Note. On and after any redemption date, interest will cease to
accrue on the Notes or portions thereof called for redemption unless the Issuer
shall fail to redeem any such Note.

REDEMPTION FOR CHANGES IN CANADIAN WITHHOLDING TAXES

  The Notes will be subject to redemption as a whole, but not in part, at the
option of the Issuer at any time, on not less than 30 nor more than 60 days'
prior written notice, at 100% of the principal amount thereof, plus accrued and
unpaid interest thereon (if any) to but excluding the redemption date, in the
event the Issuer has become, or would become, obligated to pay, on the next date
on which any amount would be payable with respect to the Notes, any Additional
Amounts (as defined in "Additional Amounts") as a result of a change in the laws
(including any regulations thereunder) of Canada (or any political subdivision
or taxing authority thereof or therein), or any change in any official position
regarding the application or interpretation of such laws or regulations, which
change is announced or becomes effective on or after the Issue Date.

ADDITIONAL AMOUNTS

  All payments made by the Issuer under or with respect to the Notes will be
made free and clear of, and without withholding or deduction for or on account
of, any present or future tax, duty, levy, impost, assessment or other
governmental charge imposed or levied by or on behalf of the government of
Canada or of any province or territory thereof or by any authority or agency
therein or thereof having power to tax ("Taxes"), unless the Issuer is required
to withhold or deduct Taxes by law or by the interpretation or administration
thereof by the relevant governmental authority or agency.  If the Issuer is so
required to withhold or deduct any amount for or on account of Taxes from any
payment made under or with respect to the Notes, the Issuer will pay such
additional amounts ("Additional Amounts") as may be necessary so that the net
amount received by each holder (including Additional Amounts) after such
withholding or deduction will not be less than the amount the holder would have
received if such Taxes had not been withheld or deducted; provided, that no
Additional Amounts will be payable with respect to a payment made to a holder
(an "Excluded Holder") (i) with which the Issuer does not deal at arm's length
(within the meaning of the Income Tax Act (Canada)) at the time of making such
payment, or (ii) which is subject to such Taxes by reason of its being connected
with Canada or any province or territory thereof otherwise than by the mere
acquisition, holding or disposition of Notes or the receipt of payments
thereunder.  The Issuer will also (i) make such withholding or deduction and
(ii) remit the full amount deducted or withheld to the relevant governmental
authority in accordance with applicable law, the Issuer will furnish to the
holders (other than an Excluded Holder), within 30 days after the date the
payment of any Taxes is due pursuant to applicable law, certified copies of tax
receipts evidencing such payment by the Issuer.  The Issuer will indemnify and
hold harmless each holder (other than an Excluded Holder) and upon written
request reimburse each such holder for the amount of (i) any Taxes so levied or
imposed and paid by such holder as a result of payments made under or with
respect to the Notes, (ii) any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, and (iii) any Taxes imposed
with respect to any reimbursement under (i) or (ii), but excluding any such
Taxes on such holder's net income.

  At least 30 days prior to each date on which any payment under or with respect
to the Notes is due and payable, if the Issuer will be obligated to pay
Additional Amounts with respect to such payment, the Issuer will deliver to the
Trustee an Officers' Certificate stating the fact that such Additional Amounts
will be payable, the amounts so payable and will set forth such other
information necessary to enable the Trustee to pay such Additional Amounts to
holders (other than an Excluded Holder) on the payment date.  Whenever in the
Indenture there is mentioned in any context the payment of principal (and
premium, if any), redemption price, interest or any other amount payable under
or with respect to any Note, such mention shall be deemed to include mention of
the payment of Additional Amounts to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof.

Considerations."

SUBORDINATION OF DOMESTIC GUARANTEES

  Each Domestic Guarantee is, to the extent and in the manner provided in the
Indenture, subordinated in right of payment to the prior indefeasible payment
and satisfaction in full in cash of all existing and future Senior Indebtedness
of such Domestic Guarantor.  As of May 31, 1998, there was approximately $58.8
million of Senior Indebtedness outstanding which would be senior in right of
payment to the Domestic Guarantees and $250 million of senior subordinated
indebtedness which would rank pari passu with the Domestic Guarantees.

  In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to a Domestic Guarantor or to its creditors, as
such, or to its assets, whether voluntary or involuntary, or any liquidation,
dissolution or other winding-up of a Domestic Guarantor, whether voluntary or
involuntary and whether or not involving insolvency or bankruptcy, or any
general assignment for the benefit of creditors or any other marshalling of
assets or liabilities of a Domestic Guarantor (except in connection with the
merger or consolidation of a Domestic Guarantor or its liquidation or
dissolution following the transfer of substantially all of its assets, upon the
terms and conditions permitted under the circumstances described under "Mergers,
Consolidations or Sale of Assets") (all of the foregoing referred to herein
individually as a "Bankruptcy Proceeding" and collectively as "Bankruptcy
Proceedings"), the holders of Senior Indebtedness of the Domestic Guarantors
will be entitled to receive payment and satisfaction in full in cash of all
amounts due on or in respect of all Senior Indebtedness of the Domestic
Guarantors before the holders of the Notes are entitled to receive or retain any
payment or distribution of any kind on account of the Notes pursuant to the
Domestic Guarantees.  In the event that, notwithstanding the foregoing, the
Trustee or any holder of Notes receives any payment or distribution of assets of
the Domestic Guarantors of any kind, whether in cash, property or securities,
including, without limitation, by way of set-off or otherwise, in respect of the
Notes pursuant to the Domestic Guarantees before all Senior Indebtedness of the
Domestic Guarantors is paid and satisfied in full in cash, then such payment or
distribution will be held by the recipient in trust for the benefit of holders
of such Senior Indebtedness and will be immediately paid over or delivered to
the holders of such Senior Indebtedness or their representative or
representatives to the extent necessary to make payment in full in cash of all
such Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of such
Senior Indebtedness.  By reason of such subordination, in the event of
liquidation or insolvency, creditors of the Domestic Guarantors who are holders
of Senior Indebtedness of the Domestic Guarantors may recover more, ratably,
than other creditors of the Domestic Guarantors, and creditors of the Domestic
Guarantors who are not holders of Senior Indebtedness or of the Notes may
recover more, ratably, than the holders of the Notes.

  No payment or distribution of any assets or securities of the Domestic
Guarantors of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other Indebtedness of the Domestic Guarantors being
subordinated to the payment of the Notes by the Domestic Guarantors) may be made
by or on behalf of the Domestic Guarantors, including, without limitation, by
way of set-off or otherwise, for or on account of the Notes pursuant to the
Domestic Guarantees, or for or on account of the purchase, redemption,
defeasance or other acquisition of the Notes pursuant to the Domestic
Guarantees, and neither the Trustee nor any holder or owner of any Notes shall
take or receive from any Domestic Guarantor, directly or indirectly in any
manner, payment in respect of all or any portion of Notes pursuant to the
Domestic Guarantees following the delivery by the representative of the holders
of Designated Senior Indebtedness ("Representative") to the Trustee of written
notice of (i) the occurrence of a Payment Default or (ii) the occurrence of a
Non-Payment Event of Default on Designated Senior Indebtedness and the
acceleration of the maturity of such Designated Senior Indebtedness in
accordance with its terms, and, in any such event, such prohibition shall
continue until such Payment Default is cured, waived in writing or ceases to
exist or such acceleration has been rescinded or otherwise cured.  At such time
as the prohibition set forth in the preceding sentence shall no longer be in
effect, subject to the provisions of the following paragraph, the Domestic
Guarantors shall, if applicable, resume making any and all required payments on
account of the Notes pursuant to the Domestic Guarantees, including any missed
payments.

                                      -80-
<PAGE>
 
  Upon the occurrence of a Non-Payment Event of Default on Designated Senior
Indebtedness, no payment or distribution of any assets or securities of the
Domestic Guarantors of any kind or character (including, without limitation,
cash, property and any payment or distribution which may be payable or
deliverable by reason of the payment of any other Indebtedness of the Domestic
Guarantors being subordinated to the payment of the Domestic Guarantees by the
Domestic Guarantors) may be made by the Domestic Guarantors, including, without
limitation, by way of set-off or otherwise, on account of the Notes pursuant to
the Domestic Guarantees, or for or on account of the purchase, redemption,
defeasance or other acquisition of Notes pursuant to the Domestic Guarantees,
and neither the Trustee nor any holder or owner of any Notes shall take or
receive from any Domestic Guarantors (or any U.S. Restricted Subsidiary or U.S.
Subsidiary of such Domestic Guarantor), directly or indirectly in any manner,
payment in respect of all or any portion of the Notes pursuant to the Domestic
Guarantees, for a period (a "Payment Blockage Period") commencing on the date of
receipt by the Trustee of written notice from the Representative of such Non-
Payment Event of Default unless and until (subject to any blockage of payments
that may then be in effect under the preceding paragraph) the earliest of (x)
more than 179 days shall have elapsed since receipt of such written notice by
the Trustee, (y) such Non-Payment Event of Default shall have been cured or
waived in writing or shall have ceased to exist or such Designated Senior
Indebtedness shall have been paid in full or (z) such Payment Blockage Period
shall have been terminated by written notice to the Domestic Guarantors or the
Trustee from such Representative, after which, in the case of clause (x), (y) or
(z), the Domestic Guarantors shall resume making any and all required payments
in respect of the Domestic Guarantees, including, if applicable, any missed
payments.  Notwithstanding any other provision of the Indenture, in no event
shall a Payment Blockage Period commenced in accordance with the provisions of
the Indenture described in this paragraph extend beyond 179 days from the date
of the receipt by the Trustee of the notice referred to above (the "Initial
Blockage Period").  Any number of additional Payment Blockage Periods may be
commenced during the Initial Blockage Period; provided, however, that no such
additional Payment Blockage Period shall extend beyond the Initial Blockage
Period.  After the expiration of the Initial Blockage Period, no Payment
Blockage Period may be commenced until at least 180 consecutive days have
elapsed from the last day of the Initial Blockage Period.  Notwithstanding any
other provision of the Indenture, no event of default with respect to Designated
Senior Indebtedness (other than a Payment Default) which existed or was
continuing on the date of the commencement of any Payment Blockage Period
initiated by the Representative shall be, or be made, the basis for the
commencement of a second Payment Blockage Period initiated by the
Representative, whether or not within the Initial Blockage Period, unless such
event of default shall have been cured or waived for a period of not less than
90 consecutive days.

  If any Domestic Guarantor fails to make any payment on any Domestic Guarantee,
when due or within any applicable grace period, whether or not on account of
payment blockage provisions, such failure constitutes an Event of Default under
the Indenture and would, subject to the above provision, enable the holders of
the Notes to accelerate the maturity thereof.  See "Events of Default."

  A holder of Notes by his acceptance of Notes agrees to be bound by such
provisions and authorizes and expressly directs the Trustee, on his behalf, to
take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purpose.

CERTAIN COVENANTS

                                      -81-
<PAGE>
 
  The Indenture contains, among others, the following covenants:

  Limitation on Additional Indebtedness

  Pierce Leahy will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, incur (as defined) any Indebtedness (including Acquired
Indebtedness) unless (a) after giving effect to the incurrence of such
Indebtedness and the receipt and application of the proceeds thereof, the ratio
of total Indebtedness of Pierce Leahy and its Restricted Subsidiaries to the
Adjusted EBITDA of Pierce Leahy is less than 6.5 to 1; provided, however, that
if the Indebtedness which is the subject of a determination under this provision
is Acquired Indebtedness, or Indebtedness incurred in connection with the
simultaneous acquisition of any Person, business, property or assets, then such
ratio shall be determined by giving effect (on a pro forma basis, as if the
transaction had occurred at the beginning of the four quarter period ending at
the end of the last fiscal quarter of such Person or business for which
financial statements are available) to the incurrence or assumption of such
Acquired Indebtedness or such other Indebtedness by Pierce Leahy or a Restricted
Subsidiary; and (b) no Default or Event of Default shall have occurred and be
continuing at the time or as a consequence of the incurrence of such
Indebtedness.

  Notwithstanding the foregoing, Pierce Leahy and its Restricted Subsidiaries
may incur Permitted Indebtedness; provided, that no Domestic Guarantor may incur
any Permitted Indebtedness, without meeting the Indebtedness incurrence
provisions of the preceding paragraph, that ranks pari passu or junior in right
of payment to the Domestic Guarantees and that has a maturity or mandatory
sinking fund payment prior to the maturity of the Notes.

  Limitation on Restricted Payments

  Pierce Leahy will not make, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make, any Restricted Payment, unless:

   (a) no Default or Event of Default shall have occurred and be continuing at
 the time of or immediately after giving effect to such Restricted Payment;

   (b) immediately after giving pro forma effect to such Restricted Payment,
 Pierce Leahy or a Restricted Subsidiary could incur $1.00 of additional
 Indebtedness (other than Permitted Indebtedness) under the covenant set forth
 under "Limitation on Additional Indebtedness"; and

   (c) immediately after giving effect to such Restricted Payment, the aggregate
 of all Restricted Payments declared (except to the extent not made on the
 payment date) or made after the Issue Date does not exceed the sum of (1) 50%
 of the cumulative Consolidated Net Income of Pierce Leahy subsequent to the
 Issue Date (or minus 100% of any cumulative deficit in Consolidated Net Income
 during such period) and (2) 100% of the aggregate Net Proceeds and the fair
 market value of securities or other property received by Pierce Leahy or the
 Issuer from the issue or sale, after the Issue Date, of Capital Stock (other
 than Disqualified Capital Stock or Capital Stock of Pierce Leahy or the Issuer
 issued to any Subsidiary of Pierce Leahy) of Pierce Leahy or the Issuer or any
 Indebtedness or other securities of Pierce Leahy or the Issuer convertible into
 or exercisable or exchangeable for Capital Stock (other than Disqualified
 Capital Stock) of Pierce Leahy or the Issuer which has been so converted or
 exercised or exchanged, as the case may be, and (3) $3,000,000.  For purposes
 of determining under this clause (c) the amount expended for Restricted
 Payments, cash distributed shall be valued at the face amount thereof and
 property other than cash shall be valued at its fair market value.

  Notwithstanding the foregoing, the provisions of this covenant shall not
prohibit (i) the payment of any distribution within 60 days after the date of
declaration thereof, if at such date of declaration such payment would comply
with the provisions of the Indenture, (ii) the retirement of any shares of
Capital Stock of Pierce Leahy or the Issuer or subordinated Indebtedness by
conversion into, or by or in exchange for, shares of Capital Stock (other than
Disqualified Capital Stock), or out of, the Net Proceeds of the substantially
concurrent sale (other than to a Subsidiary of Pierce Leahy) of other shares of
Capital Stock of Pierce Leahy (other than Disqualified Capital Stock), (iii) the
redemption or retirement of Indebtedness of the Issuer subordinated to the Notes
in the case of the Issuer or of a Guarantor subordinated to its respective
Guarantee in exchange for, by conversion into, or out of the Net Proceeds of, a
substantially concurrent sale or incurrence of Indebtedness (other than any
Indebtedness owed to a Subsidiary) of the Issuer or a Guarantor that is
contractually subordinated in right of payment to the Notes in the case of
Issuer or such Guarantor's Guarantee, as the case may be, to at least the same
extent as the subordinated Indebtedness being redeemed or retired, (iv) the
retirement of any shares of Disqualified Capital Stock by conversion into, or by
exchange for, shares of Disqualified Capital Stock, or out of the Net Proceeds
of the substantially concurrent sale (other than to a Subsidiary of Pierce
Leahy) of other shares of Disqualified Capital Stock, (v) Permitted Tax
Distributions, (vi) payments to employees of Pierce Leahy for repurchases of
stock or repurchases pursuant to the Pierce Leahy Nonqualified Stock Option
Plan; provided, however, that the aggregate amount of all such payments under
this clause (vi) does not exceed $2,000,000 in the aggregate, exclusive of
amounts funded by insurance proceeds

                                      -82-
<PAGE>
 
and, provided, further, that with respect to clause (vi) (other than with
respect to payments funded by insurance proceeds) no Default or Event of Default
shall have occurred and be continuing at the time of any such distribution or
payment or will occur immediately after giving effect to any such distribution
or payment; and, provided, further, that, in determining the aggregate amount of
all Restricted Payments made subsequent to the Issue Date, all distributions or
payments made pursuant to clause (vi) (exclusive of insurance proceeds) shall be
included.

  Not later than the date of making any Restricted Payment, Pierce Leahy and the
Issuer shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this covenant were computed, which calculations may be
based upon Pierce Leahy's latest available financial statements, and that no
Default or Event of Default exists and is continuing and no Default or Event of
Default will occur immediately after giving effect to such Restricted Payment.

  Limitation on Senior Subordinated Debt

  Pierce Leahy will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, incur, contingently or otherwise, any Indebtedness
(other than the Notes and the Guarantees, as the case may be) that is both (i)
subordinate in right of payment to any Senior Indebtedness of Pierce Leahy or
its Restricted Subsidiaries, as the case may be, and (ii) senior in right of
payment to the Notes, with respect to the Issuer, or a Guarantor's Guarantee,
with respect to such Guarantor, as the case may be.  For purposes of this
covenant, Indebtedness is deemed to be senior in right of payment to a Domestic
Guarantee if it is not explicitly subordinate in right of payment to Senior
Indebtedness at least to the same extent as the Domestic Guarantees are
subordinate to Senior Indebtedness.

  Limitations on Investments

  Pierce Leahy will not, and will not permit any of its Restricted Subsidiaries
to, make any Investment other than (i) a Permitted Investment or (ii) an
Investment that is made as a Restricted Payment in compliance with the
"Limitation on Restricted Payments" covenant, after the Issue Date.

 Limitations on Liens

  Pierce Leahy will not, and will not permit any of its Restricted Subsidiaries
to, create, incur or otherwise cause or suffer to exist or become effective any
Liens of any kind (other than Permitted Liens) upon any property or asset of
Pierce Leahy or any Restricted Subsidiary or any shares of stock or debt of any
Restricted Subsidiary which owns property or assets, now owned or hereafter
acquired, in any case which secures Indebtedness pari passu with or subordinated
to the Notes with respect to the Issuer or a Guarantor's Guarantee with respect
to the respective Guarantor unless (i) if such Lien secures Indebtedness which
is pari passu with the Notes in the case of the Issuer or a Guarantee with
respect to the respective Guarantor, then the Notes or such Guarantee, as
applicable, are secured on an equal and ratable or senior basis with the
obligations so secured until such time as such obligation is no longer secured
by a Lien or (ii) if such Lien secures Indebtedness which is subordinated to the
Notes in the case of the Issuer or a Guarantor's Guarantee in the case of a
Guarantor, any such Lien shall be subordinated to the Lien granted to the
holders of the Notes in the same collateral to the same extent as such
subordinated Indebtedness is subordinated to the Notes or such Guarantee, as
applicable.

                                      -83-
<PAGE>
 
  Limitation on Transactions with Affiliates

  Pierce Leahy will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, enter into any transaction or series of related
transactions (including, without limitation, the sale, purchase, exchange or
lease of assets, property or services) with any Affiliate (including entities in
which Pierce Leahy or any of its Restricted Subsidiaries own a minority
interest) or holder of 10% or more of Pierce Leahy's Common Stock (an "Affiliate
Transaction") or extend, renew, waive or otherwise modify the terms of any
Affiliate Transaction entered into prior to the Issue Date unless (i) such
Affiliate Transaction is between or among Pierce Leahy and its Wholly-Owned
Subsidiaries; (ii) such Affiliate Transaction is solely between or among Wholly-
Owned Subsidiaries of Pierce Leahy; or (iii) the terms of such Affiliate
Transaction are fair and reasonable to Pierce Leahy or such Restricted
Subsidiary, as the case may be, and the terms of such Affiliate Transaction are
at least as favorable as the terms which could be obtained by Pierce Leahy or
such Restricted Subsidiary, as the case may be, in a comparable transaction made
on an arm's-length basis between unaffiliated parties; provided, however, that
Pierce Leahy and its Restricted Subsidiaries may renew any then existing
Affiliate Transaction through either a renewal option or upon expiration of an
arrangement on substantially similar terms to those in effect immediately
preceding such expiration.  In any Affiliate Transaction involving an amount or
having a value in excess of $1 million which is not permitted under clause (i)
or (ii) above, Pierce Leahy must obtain a resolution of the Board of Directors
certifying that such Affiliate Transaction complies with clause (iii) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors.  In transactions with a value
in excess of $3 million which are not permitted under clause (i) or (ii) above,
Pierce Leahy must obtain a written opinion as to the fairness from a financial
point of view of such a transaction from an independent investment banking firm
of national standing or real estate firm of national standing (as the case may
be).

  The foregoing provisions will not apply to (i) any Restricted Payment that is
not prohibited by the provisions described under "Limitations on Restricted
Payments" contained herein, (ii) any transaction, approved by the Board of
Directors of Pierce Leahy in good faith, with an officer, director, employee or
consultant of Pierce Leahy or of any Subsidiary in his or her capacity as an
officer, director, employee or consultant entered into in the ordinary course of
business, including compensation, indemnity and employee benefit arrangements
with any officer, director, employee or consultant of Pierce Leahy or of any
Subsidiary, or (iii) customary investment banking, underwriting, placement agent
or financial advisor fees paid in connection with services rendered to Pierce
Leahy or any Subsidiary.

  Limitation on Creation of Subsidiaries

  Pierce Leahy will not create or acquire, nor permit any of its Restricted
Subsidiaries to create or acquire, any Subsidiary other than (i) a Restricted
Subsidiary existing as of the date of the Indenture, (ii) a Restricted
Subsidiary that is acquired or created after the date of the Indenture, or (iii)
an Unrestricted Subsidiary; provided, however, that (a) each Restricted
Subsidiary organized under the laws of the United States or any state thereof or
the District of Columbia acquired or created pursuant to clause (ii) at the time
it has either assets or shareholder's equity in excess of $5,000 and (b) each
Restricted Subsidiary organized under the laws of Canada or any province thereof
acquired or created pursuant to clause (ii) which is not prohibited by the laws
of Canada or any province thereof from acting as a guarantor of the Notes, at
the time it has either assets or shareholders' equity in excess of $5,000, shall
execute a subordinated guarantee in the case of a Domestic Guarantor and a
senior guarantee in the case of a Canadian Guarantor, each in the form attached
to the Indenture and reasonably satisfactory in form and substance to the
Trustee (and with such documentation relating thereto as the Trustee shall
require, including, without limitation a supplement or amendment to the
Indenture and opinions of counsel as to the enforceability of such guarantee).
See "Guarantees."

  Limitation on Certain Asset Sales

  Pierce Leahy will not, and will not permit any of its Restricted Subsidiaries
to, consummate an Asset Sale unless (i) Pierce Leahy or its Restricted
Subsidiaries, as the case may be, receives consideration at the time of such
sale
or other disposition at least equal to the fair market value thereof (as
determined for Asset Sales other than eminent domain, condemnation or similar
government proceedings in good faith by Pierce Leahy's Board of Directors, and
evidenced by a board resolution); (ii) not less than 85% of the consideration
received by Pierce Leahy or its Subsidiaries, as the case may be, is in the form
of cash or Temporary Cash Investments; and (iii) the Asset Sale Proceeds
received by Pierce Leahy or such Restricted Subsidiary are applied (a) first, to
the extent Pierce Leahy or such Restricted Subsidiary elects, or is required, to
prepay, repay or purchase debt under any then existing Senior Indebtedness of
Pierce Leahy or any Restricted Subsidiary within 180 days following the receipt
of the Asset Sale Proceeds from any Asset Sale; (b) second, to the extent of the
balance of Asset Sale Proceeds after application as described above, to the
extent Pierce Leahy or such Restricted Subsidiary elects, to an investment in
assets (including Capital Stock or other securities purchased in connection with
the acquisition of Capital Stock or property of another Person) used or useful
in businesses similar or ancillary to the business of Pierce Leahy or a
Restricted Subsidiary as conducted at the time of such Asset Sale, provided that
such investment occurs or Pierce Leahy or a Restricted Subsidiary enters into
contractual 

                                      -84-
<PAGE>
 
commitments to make such investment, subject only to customary conditions (other
than the obtaining of financing), on or prior to the 181st day following receipt
of such Asset Sale Proceeds (the "Reinvestment Date") and Asset Sale Proceeds
contractually committed are so applied within 270 days following the receipt of
such Asset Sale Proceeds; and (c) third, if on the Reinvestment Date with
respect to any Asset Sale, the Available Asset Sale Proceeds exceed $10 million,
Pierce Leahy or such Restricted Subsidiary, as applicable, shall apply an amount
equal to such Available Asset Sale Proceeds to an offer to repurchase the Notes,
or any Indebtedness ranking pari passu with the Notes with respect to
Indebtedness of the Issuer or the relevant Guarantee with respect to
Indebtedness of a Guarantor, which Indebtedness contains similar provisions
requiring Pierce Leahy or a Restricted Subsidiary to repurchase such
Indebtedness, at a purchase price in cash equal to 100% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of repurchase (an
"Excess Proceeds Offer"); provided, however, that prior to making any such
Excess Proceeds Offer, Pierce Leahy or such Restricted Subsidiary may, to the
extent required pursuant to the terms of Indebtedness outstanding as of the
Issue Date, such as the 1996 Notes and the 1997 Notes, offer to use such
Available Asset Sale Proceeds to repurchase and use all or a portion of such
Available Asset Sale Proceeds to repurchase such Indebtedness. If an Excess
Proceeds Offer is not fully subscribed, Pierce Leahy or such Restricted
Subsidiary may retain the portion of the Available Asset Sale Proceeds not
required to repurchase Notes for general corporate purposes. If the aggregate
principal amount of Notes tendered pursuant to such Excess Proceeds Offer is
more than the amount of the Available Asset Sale Proceeds, the Notes tendered
will be repurchased on a pro rata basis or by such other method as the Trustee
shall deem fair and appropriate.

  If the Issuer is required to make an Excess Proceeds Offer, the Issuer shall
mail, within 30 days following the Reinvestment Date (or within 120 days
following the Reinvestment Date if Pierce Leahy or a Restricted Subsidiary is
required to make an offer to repurchase Indebtedness (other than the Notes)
outstanding as of the Issue Date), a notice to the holders stating, among other
things:  (1) that such holders have the right to require Pierce Leahy to apply,
or to cause a Restricted Subsidiary to apply, the Available Asset Sale Proceeds
to repurchase such Notes at a purchase price in cash equal to 100% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of purchase; (2) the purchase date, which shall be no earlier than 30 days and
not later than 60 days from the date such notice is mailed; (3) the
instructions, determined by the Issuer, that each holder must follow in order to
have such Notes repurchased; and (4) the calculations used in determining the
amount of Available Asset Sale Proceeds to be applied to the repurchase of such
Notes.

 Limitation on Preferred Stock of Restricted Subsidiaries

  Pierce Leahy will not permit any Restricted Subsidiary to issue any Preferred
Stock (except Preferred Stock to Pierce Leahy or a Restricted Subsidiary) or
permit any Person (other than Pierce Leahy or a Subsidiary) to hold any such
Preferred Stock unless Pierce Leahy or such Restricted Subsidiary would be
entitled to incur or assume Indebtedness under the covenant described under
"Limitation on Additional Indebtedness" in the aggregate principal amount equal
to the aggregate liquidation value of the Preferred Stock to be issued;
provided, however, that the Issuer and any Restricted Subsidiary that guarantees
the Notes shall be permitted to issue Preferred Stock that is not Disqualified
Capital Stock.

                                      -85-
<PAGE>
 
 Limitation on Capital Stock of Restricted Subsidiaries

  Pierce Leahy will not (i) sell, pledge, hypothecate or otherwise convey or
dispose of any Capital Stock of a Restricted Subsidiary (other than under the
terms of the Credit Facility or under the terms of any Designated Senior
Indebtedness or as permitted under "Limitations on Liens") or (ii) permit any of
its Restricted Subsidiaries to issue any Capital Stock, other than to Pierce
Leahy or a Wholly-Owned Subsidiary of Pierce Leahy.  The foregoing restrictions
shall not apply to an Asset Sale made in compliance with "Limitation on Certain
Asset Sales" or the issuance of Preferred Stock in compliance with the covenants
described under "Limitation on Preferred Stock of Restricted Subsidiaries."

 Limitation on Sale and Lease-Back Transactions

  Pierce Leahy will not, and will not permit any Restricted Subsidiary to, enter
into any Sale and Lease-Back Transaction unless (i) the consideration received
in such Sale and Lease-Back Transaction is at least equal to the fair market
value of the property sold, as determined by a board resolution of Pierce Leahy,
and (ii) Pierce Leahy or a Restricted Subsidiary could incur the Attributable
Indebtedness in respect of such Sale and Lease-Back Transaction in compliance
with the covenant described under "Limitation on Additional Indebtedness."

 Payments for Consent

  Neither Pierce Leahy nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any Notes for or as an inducement
to any consent, waiver or amendment of any of the terms or provisions of the
Indenture or the Notes unless such consideration is offered to be paid or agreed
to be paid to all holders of the Notes which so consent, waive or agree to amend
in the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

 CHANGE OF CONTROL OFFER

  Within 30 days of the occurrence of a Change of Control of Pierce Leahy, the
Issuer shall notify the Trustee in writing of such occurrence and shall make an
offer to purchase (the "Change of Control Offer") the outstanding Notes at a
purchase price equal to 101% of the principal amount thereof plus any accrued
and unpaid interest thereon to the Change of Control Payment Date (as
hereinafter defined) (such applicable purchase price being hereinafter referred
to as the "Change of Control Purchase Price") in accordance with the procedures
set forth in this covenant.  See "Certain Definitions-Change of Control" herein.

  Within 30 days of the occurrence of a Change of Control, the Issuer also shall
(i) cause a notice of the Change of Control Offer to be sent at least once to
the Dow Jones News Service or similar business news service in the United States
and (ii) send by first-class mail, postage prepaid, to the Trustee and to each
holder of the Notes, at the address appearing in the register maintained by the
Registrar of the Notes, a notice stating:

   (1) that the Change of Control Offer is being made pursuant to this covenant
 and that all Notes tendered will be accepted for payment, and otherwise subject
 to the terms and conditions set forth herein;

   (2) the Change of Control Purchase Price and the purchase date (which shall
 be a Business Day no earlier than 20 business days and no later than 60 days
 from the date such notice is mailed (the "Change of Control Payment Date"));

  (3)  that any Note not tendered will not be purchased and will continue to
 accrue interest;

   (4) that, unless the Issuer defaults in the payment of the Change of Control
 Purchase Price, any Notes accepted for payment pursuant to the Change of
 Control Offer shall cease to accrue interest after the Change of Control
 Payment Date;

                                      -86-
<PAGE>
 
   (5) that holders accepting the offer to have their Notes purchased pursuant
 to a Change of Control Offer will be required to surrender the Notes to the
 paying agent at the address specified in the notice prior to the close of
 business on the Business Day preceding the Change of Control Payment Date;

   (6) that holders will be entitled to withdraw their acceptance if the Paying
 Agent receives, not later than the close of business on the third Business Day
 preceding the Change of Control Payment Date, a facsimile transmission or
 letter setting forth the name of the holder, the principal amount of the Notes
 delivered for purchase, and a statement that such holder is withdrawing his
 election to have such Notes purchased;

   (7) that holders whose Notes are being purchased only in part will be issued
 new Notes equal in principal amount to the unpurchased portion of the Notes
 surrendered, provided that each Note purchased and each such new Note issued
 shall be in an original principal amount in denominations of $1,000 and
 integral multiples thereof;

   (8) any other procedures that a holder must follow to accept a Change of
 Control Offer or effect withdrawal of such acceptance; and

   (9) the name and address of the paying agent.

  On the Change of Control Payment Date, the Issuer shall, to the extent lawful,
(i) accept for payment Notes or portions thereof or beneficial interests under a
Global Note properly tendered pursuant to the Change of Control Offer, (ii)
deposit with the paying agent money sufficient to pay the Change of Control
Purchase Price of all Notes or portions thereof or beneficial interests so
tendered and (iii) deliver or cause to be delivered to the Trustee Notes so
accepted together with an Officers' Certificate stating the Notes or portions
thereof tendered to the Issuer.  The paying agent shall promptly (1) mail to
each holder of Notes so accepted and (2) cause to be credited to the respective
accounts of the holders under a Global Note of beneficial interest so accepted
payment in an amount equal to the Change of Control Purchase Price for such
Notes, and the Issuer shall execute and issue, and the Trustee shall promptly
authenticate and mail to each such holder, a new Note equal in principal amount
to any unpurchased portion of the Notes surrendered and shall issue a Global
Note equal in principal amount to any unpurchased portion of beneficial interest
so surrendered; provided that each such new Note shall be issued in an original
principal amount in denominations of $1,000 and integral multiples thereof.

  The Indenture requires that if the Credit Facility is in effect, or any
amounts are owing thereunder or in respect thereof, at the time of the
occurrence of a Change of Control, prior to the mailing of the notice to holders
described in the preceding paragraph, but in any event within 30 days following
any Change of Control, Pierce Leahy and the Issuer will covenant to (i) repay in
full all obligations under or in respect of the Credit Facility or offer to
repay in full all obligations under or in respect of the Credit Facility and
repay the obligations under or in respect of the Credit Facility of each lender
who has accepted such offer or (ii) obtain the requisite consent under the
Credit Facility to permit the repurchase of the Notes as described above Pierce
Leahy and the Issuer must first comply with the covenant described in the
preceding sentence before it shall be required to purchase Notes in the event of
a Change of Control; provided that Pierce Leahy's or the Issuer's failure to
comply with the covenant described in the preceding sentence constitutes an
Event of Default described in clause (iii) under "Events of Default" below if
not cured within 60 days after the notice required by such clause.  As a result
of the foregoing, a holder of the Notes may not be able to compel the Issuer to
purchase the Notes unless the Issuer or Pierce Leahy is able at the time to
refinance all of the obligations under or in respect of the Credit Facility or
obtain requisite consents under the Credit Facility.

  The Indenture provides that, (i) if Pierce Leahy or any Subsidiary thereof has
issued any outstanding (a) Indebtedness that is subordinated in right of payment
to the Notes in the case of the Issuer or a Guarantee in the case of a Guarantor
making such Guarantee or (b) Preferred Stock, and Pierce Leahy or such
Subsidiary is required to make a change of control offer or to make a
distribution with respect to such subordinated Indebtedness or Preferred Stock
in the event of a change of control, Pierce Leahy or such Subsidiary, as the
case may be, shall not consummate any such offer or distribution with respect to
such subordinated Indebtedness or Preferred Stock until such time as the Issuer
shall have paid the Change of Control Purchase Price in full to the holders of
Notes that have accepted the Change of Control Offer and shall otherwise have
consummated the Change of Control Offer made to holders of the Notes and (ii)
the Issuer and the Guarantors will not issue Indebtedness that is subordinated
in right of payment to the Notes in the case of the Issuer or a Guarantee in the
case of a Guarantor making such Guarantee or Preferred Stock with change of
control provisions requiring the payment of such indebtedness or Preferred Stock
prior to the payment of the Notes or such Guarantee, as the case may be, in the
event of a Change of Control under the Indenture.

  In the event that a Change of Control occurs and the holders of Notes exercise
their right to require the Issuer to purchase Notes, if such purchase
constitutes a "tender offer" for purposes of Rule 14e-1 under the Exchange Act
at that time, the Issuer will comply with the requirements of Rule 14e-1 as then
in effect with respect to such repurchase.

  The Issuer's ability to purchase the Notes will be limited by Issuer's and
Pierce Leahy's then available financial resources and, if such financial
resources are insufficient, the Issuer's or Pierce Leahy's ability to arrange
financing to effect such purchases.  There can be no assurance that the Issuer
or Pierce Leahy will have sufficient funds to repurchase the Notes upon a Change
of Control or that the Issuer or Pierce Leahy will be able to arrange financing
for such purpose.  In addition, Pierce Leahy has a similar obligation with
respect to the 1996 Notes and the 1997 Notes upon a Change of Control.  Such
obligations of Pierce Leahy rank pari passu with the obligation to make a Change
of Control Offer under the Notes pursuant to its Guarantee.

MERGER, CONSOLIDATION OR SALE OF ASSETS

  Pierce Leahy and the Issuer will not and will not permit any Guarantor to
consolidate with, merge with or into, or transfer all or substantially all of
its assets (as an entirety or substantially as an entirety in one transaction or
a series of related transactions), to any Person unless: (i) Pierce Leahy, the
Issuer or the Guarantor, as the case may be, shall be the continuing Person, or
the Person (if other than Pierce Leahy, the Issuer or a Guarantor) formed by
such consolidation or into which Pierce Leahy, the Issuer or the Guarantor, as
the case may be, is merged or to which the properties and assets of Pierce
Leahy, the Issuer or the Guarantor, as the case may be, are transferred shall be
a corporation organized and existing under the laws of the United States or any
state thereof or the District of Columbia (and in the case of the Issuer or a
Canadian Guarantor, a corporation organized and existing under the laws of
Canada or any province thereof) and shall expressly assume, by a supplemental
indenture, executed and delivered to the Trustee, in form satisfactory to the
Trustee, all of the obligations of Pierce Leahy, the Issuer or the Guarantor, as
the case may be, under the Notes and the Indenture, and the obligations under
the Indenture shall remain in full force and effect; (ii) immediately before and
immediately after giving effect to such transaction, no Default or Event of
Default shall have occurred and be continuing; and (iii) immediately after
giving effect to such transaction on a pro forma basis Pierce Leahy, a
Restricted Subsidiary or such Person could incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) under the covenant set forth
under "Limitation on Additional Indebtedness"; provided, however, that (a) a
Guarantor other than Pierce Leahy may merge into the Issuer, Pierce Leahy or
another Guarantor, (b) the Issuer may merge into a Canadian Guarantor or another
corporation or limited liability company organized and existing under the laws
of Canada or any province thereof for the purpose of converting into a limited
liability company or to change the Issuer's jurisdiction of incorporation, and
(c) the Issuer or a Canadian Guarantor can transfer a portion of its assets to
the Issuer or another Canadian Guarantor, in the case of (a), (b) or (c),
without complying with this clause (iii).

                                      -88-
<PAGE>
 
  In connection with any consolidation, merger or transfer of assets
contemplated by this provision, Pierce Leahy and the Issuer shall deliver, or
cause to be delivered, to the Trustee, in form and substance reasonably
satisfactory to the Trustee, an Officers' Certificate and an opinion of counsel,
each stating that such consolidation, merger or transfer and the supplemental
indenture in respect thereto comply with this provision and that all conditions
precedent herein provided for relating to such transaction or transactions have
been complied with.

GUARANTEES

  The Notes will be guaranteed on an unsecured senior subordinated basis by the
Domestic Guarantors.  The obligations of each Domestic Guarantor will be limited
to the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Domestic Guarantor (including, without limitation, any
guarantees of Senior Indebtedness) and after giving effect to any collections
from or payments made by or on behalf of any other Domestic Guarantor in respect
of the obligations of such other Domestic Guarantor under its Domestic Guarantee
or pursuant to its contribution obligations under the Indenture, result in the
obligations of such Domestic Guarantor under the Domestic Guarantee not
constituting a fraudulent conveyance or fraudulent transfer under federal or
state law.  Each Domestic Guarantor that makes a payment or distribution under a
Domestic Guarantee will be entitled to a contribution from each other Domestic
Guarantor in a pro rata amount based on the Adjusted Net Assets of each Domestic
Guarantor.

  The Notes will be guaranteed on an unsecured senior basis by the Canadian
Guarantors, to the extent permitted by law, including financial assistance
restrictions imposed by corporate legislation.  All payments pursuant to the
Canadian Guarantees by the Canadian Guarantors will be effectively subordinated
to all secured indebtedness of such Canadian Guarantors to the extent of the
assets securing such indebtedness.

  A Guarantor other than Pierce Leahy will be released from all of its
obligations under its Guarantee if all or substantially all of its assets are
sold or all of its Capital Stock is sold, in each case in a transaction in
compliance with the covenants described under "Limitation on Certain Asset
Sales" and "Merger, Consolidation or Sale of Assets," or the Guarantor other
than Pierce Leahy merges with or into or consolidates with, or transfers all or
substantially all of its assets to, Pierce Leahy or another Guarantor in a
transaction in compliance with "Merger, Consolidation or Sale of Assets," and
such Guarantor has delivered to the Trustee an Officers' Certificate and an
opinion of counsel, each stating that all conditions precedent herein provided
for relating to such transaction have been complied with.

EVENTS OF DEFAULT

 The following events are defined in the Indenture as "Events of Default":

   (i)   default in payment of any principal of, or premium, if any, on the
Notes;

   (ii)  default for 30 days in payment of any interest on the Notes after such
interest becomes due and payable;

   (iii) default by the Issuer, Pierce Leahy or any other Guarantor in the
observance or performance of any other covenant in the Notes or the Indenture
for 60 days after written notice from the Trustee or the holders of not less
than 25% in aggregate principal amount of the Notes then outstanding;

   (iv)  default in the payment at final maturity of principal in an aggregate
amount of $3,000,000 or more with respect to any Indebtedness of Pierce Leahy or
any Restricted Subsidiary thereof which default shall not be cured, waived or
postponed pursuant to an agreement with the holders of such Indebtedness within
60 days after written notice as provided in the Indenture, or the acceleration
of any such Indebtedness aggregating $3,000,000 or more which acceleration shall
not be rescinded or annulled within 20 days after written notice as provided in
the Indenture;

   (v)   any final judgment or judgments which can no longer be appealed for the
payment of money in excess of $3,000,000 (which are not paid or covered by third
party insurance by financially sound insurers that have not disclaimed coverage)
shall be rendered against Pierce Leahy or any Restricted Subsidiary thereof, and
shall not be discharged for any period of 60 consecutive days during which a
stay of enforcement shall not be in effect; and

   (vi) certain events involving bankruptcy, insolvency or reorganization of the
Issuer, Pierce Leahy or any other Restricted Subsidiary.

                                      -89-
<PAGE>
 
  The Indenture provides that the Trustee may withhold notice to the holders of
the Notes of any default (except in payment of principal or premium, if any, or
interest on the Notes) if the Trustee in good faith determines it to be in the
best interest of the holders of the Notes to do so.

  The Indenture provides that if an Event of Default (other than an Event of
Default resulting from certain events of bankruptcy, insolvency or
reorganization of Pierce Leahy or the Issuer) shall have occurred and be
continuing, then the Trustee or the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding may declare to be immediately due
and payable the entire principal amount of all the Notes then outstanding plus
premium, if any, and accrued interest to the date of acceleration and (i) such
amounts shall become immediately due and payable or (ii) if there are any
amounts outstanding under or in respect of the Credit Facility such amounts
shall become due and payable upon the first to occur of an acceleration of
amounts outstanding under or in respect of the Credit Facility or five business
days after receipt by Pierce Leahy or the Issuer and the representative of the
holders of Senior Indebtedness under or in respect of the Credit Facility, of
notice of the acceleration of the Notes; provided, however, that after such
acceleration but before a judgment or decree based on acceleration is obtained
by the Trustee, the holders of a majority in aggregate principal amount of
outstanding Notes may, under certain circumstances, rescind and annul such
acceleration if all Events of Default, other than nonpayment of accelerated
principal, premium, if any, or interest, have been cured or waived as provided
in the Indenture.  In case an Event of Default resulting from certain events of
bankruptcy, insolvency or reorganization with respect to Pierce Leahy or the
Issuer shall occur, the principal, premium and interest with respect to all of
the Notes shall be due and payable immediately without any declaration or other
act on the part of the Trustee or the holders of the Notes.

  The holders of a majority in principal amount of the Notes then outstanding
shall have the right to waive any existing default or Event of Default or
compliance with any provision of the Indenture or the Notes and to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, subject to certain limitations specified in the Indenture.

  No holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless also the holders of at least 25% in aggregate principal
amount of the outstanding Notes shall have made written request and offered
reasonable indemnity to the Trustee to institute such proceeding as a trustee,
and unless the Trustee shall not have received from the holders of a majority in
aggregate principal amount of the outstanding Notes a direction inconsistent
with such request and the Trustee shall have failed to institute such proceeding
within 60 days.  However, such limitations do not apply to a suit instituted for
payment of principal, premium, if any, or interest on a Note on or after the
respective due dates expressed in such Note.

DEFEASANCE AND COVENANT DEFEASANCE

  The Indenture provides that the Issuer may elect either (a) to defease and be
discharged from any and all obligations with respect to the Notes (except for
the obligations to register the transfer or exchange of such Notes, to replace
temporary or mutilated, destroyed, lost or stolen Notes, to maintain an office
or agency in respect of the Notes and to hold monies for payment in trust)
("defeasance") or (b) to be released from its obligations with respect to the
Notes under certain covenants contained in the Indenture and described above
under "Certain Covenants" ("covenant defeasance"), upon the deposit with the
Trustee (or other qualifying trustee), in trust for such purpose, of money
and/or U.S. Government Obligations which through the payment of principal and
interest in accordance with their terms will provide money, in an amount
sufficient to pay the principal of, premium, if any, and interest on the Notes,
on the scheduled due dates therefor or on a selected date of redemption in
accordance with the terms of the Indenture things, the Issuer has delivered to
the Trustee an opinion of counsel (as specified in the Indenture) (i) to the
effect that neither the trust nor the Trustee will be required to register as an
investment company under the Investment Company Act of 1940, as amended, and
(ii) to the effect that holders of the Notes or persons in their positions will
not recognize income, gain or loss for federal income tax purposes as a result
of such deposit, defeasance and discharge and will be subject to federal income
tax on the same amount and in the same manner and at the same times, as would
have been the case if such deposit, defeasance and discharge had not occurred,
which, in the case of defeasance only, must be based upon a private letter
ruling concerning the Notes, a published ruling of the Internal Revenue Service
or a change in applicable federal income tax law.

MODIFICATION OF INDENTURE

  From time to time, the Issuer, Pierce Leahy and the Trustee may, without the
consent of holders of the Notes, modify, amend, waive, restate or supplement the
provisions of the Indenture or the Notes for certain specified purposes,
including providing for uncertificated Notes in addition to certificated Notes,
and curing any ambiguity, defect or inconsistency, or making any other change
that does not materially and adversely affect the rights of any holder.  The
Indenture contains provisions permitting the Issuer, Pierce Leahy and the
Trustee, with the consent of holders of at least a majority in principal amount
of the outstanding Notes, to modify, amend, waive or supplement the Indenture or
the Notes, except that no such modification shall,

                                      -90-
<PAGE>
 
without the consent of each holder affected thereby, (i) reduce the amount of
Notes whose holders must consent to an amendment, supplement, or waiver to the
Indenture or the Notes, (ii) reduce the rate of or change the time for payment
of interest on any Note, (iii) reduce the principal of or premium on or change
the stated maturity of any Note, (iv) make any Note payable in money other than
that stated in the Note or change the place of payment from New York, New York,
(v) change the amount or time of any payment required by the Notes or reduce the
premium payable upon any redemption of Notes, or change the time before which no
such redemption may be made, (vi) waive a default on the payment of the
principal of, interest on, or redemption payment with respect to any Note, or
(vii) take any other action otherwise prohibited by the Indenture to be taken
without the consent of each holder affected thereby.

  The consent of the holders is not necessary to approve the particular form of
a proposed amendment.  It is sufficient if such consent approves the substance
of the proposed amendment.

REPORTS TO HOLDERS

  So long as Pierce Leahy is subject to the periodic reporting requirements of
the Exchange Act, it will continue to furnish the information required thereby
to the Commission and to the holders of the Notes.  The Indenture provides that
even if Pierce Leahy is entitled under the Exchange Act not to furnish such
information to the Commission or to the holders of the Notes, it will
nonetheless continue to furnish such information to the Commission and holders
of the Notes.

COMPLIANCE CERTIFICATE

  Pierce Leahy and the Issuer will deliver to the Trustee on or before 100 days
after the end of Pierce Leahy's fiscal year and on or before 50 days after the
end of each of the first, second and third fiscal quarters in each year an
Officers' Certificate stating whether or not the signers know of any Default or
Event of Default that has occurred.  If they do, the certificate will describe
the Default or Event of Default and its status.

THE TRUSTEE

  The Trustee under the Indenture is the registrar and paying agent with regard
to the Notes.  The Indenture provides that, except during the continuance of an
Event of Default which is continuing, the Trustee will perform only such duties
as are specifically set forth in the Indenture.  During the existence of an
Event of Default which is continuing, the Trustee will exercise such rights and
powers vested in it under the Indenture and use the same degree of care and
skill in its exercise as a prudent person would exercise under the circumstances
in the conduct of such person's own affairs.

                                      -91-
<PAGE>
 
  The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of Pierce Leahy or the Issuer, to obtain payment of claims in
certain cases or to realize on certain property received by it in respect of any
such claims, as security or otherwise.  The Trustee is permitted to engage in
other transactions; provided, however, that if it acquires any conflicting
interest, it must eliminate such conflict or resign.

TRANSFER AND EXCHANGE

  Holders of the Notes may transfer or substitute Notes in accordance with the
Indenture.  The Registrar under such Indenture may require a holder, among other
things, to furnish appropriate endorsements and transfer documents, and to pay
any taxes and fees required by law or permitted by the Indenture.  The Registrar
is not required to transfer or substitute any Note selected for redemption.
Also, the Registrar is not required to transfer or substitute any Note for a
period of 15 days before the day of mailing of the notice of redemption of the
Notes to be redeemed.

  The Original Notes were issued in a transaction exempt from registration under
the Act and will be subject to the restrictions on transfer.

  The registered holder of a Note may be treated as the owner of it for all
purposes.

CERTAIN DEFINITIONS

  Set forth below is a summary of certain of the defined terms used in the
covenants contained in the Indenture.  Reference is made to the Indenture for
the full definition of all such terms as well as any other capitalized terms
used herein for which no definition is provided.

  "ACQUIRED INDEBTEDNESS" means Indebtedness of a Person (including an
Unrestricted Subsidiary) existing at the time such Person becomes a Restricted
Subsidiary or assumed in connection with the acquisition of assets from a
Person.

  "ACQUISITION EBITDA" means, without duplication, (i) EBITDA for the last four
fiscal quarters for which financial statements are available at the date of
determination (the "Acquisition EBITDA Period") with respect to a business or
Person which has been acquired by Pierce Leahy or one of its Restricted
Subsidiaries or which is the subject of a binding acquisition agreement
requiring the calculation of EBITDA for purposes of the covenant restricting the
incurrence of Indebtedness and, in each case, with respect to which financial
results on a consolidated basis with Pierce Leahy or one of its Restricted
Subsidiaries have not been made available for an entire fiscal quarter; plus

BOOK-ENTRY; DELIVERY AND FORM

Note which was sold in an offshore transactions in reliance on Regulation S
(each, a "Regulation S Global Note") or a Restricted Global Note which was
issued in reliance on Rule 144A (each, a "Restricted Global Note", and together
with the Regulation S Global Note, the "Original Global Notes").  The Original
Notes were represented by one or more Original Global Notes, in definitive,
fully registered form without interest coupons and were deposited with the
Trustee as custodian for The Depository Trust Company ("DTC" or the
"Depository") and registered in the name of a nominee of DTC for the accounts of
Euroclear and Cedel.

                                     -102-
<PAGE>
 
  The Exchange Notes will initially be issued in the form of one or more Global
Notes (collectively, the "Exchange Global Notes").  The Exchange Global Notes
will be deposited on the date of the closing of the Exchange Offer, with, or on
behalf of, and registered in the name of a nominee of the DTC.  "Global Notes"
means the Original Global Notes or the Exchange Global Notes, as the case may
be.

  Notes that are issued as described below under "--Certificated Securities"
will be issued, in registered form, without interest coupons ("Certificated
Securities").

THE GLOBAL NOTES

  Upon issuance of each Global Note, DTC or the custodian will credit, on its
internal system, the respective principal amount of the individual beneficial
interest represented by such Global Note to the accounts of Persons who have
accounts with such depository.  Such accounts initially will be designated by or
on behalf of the Initial Purchasers.  Ownership of beneficial interests in a
Global Note will be limited to Persons who have accounts with DTC
("participants") or Persons who hold interests through participants.  Ownership
of beneficial interests in the Global Note will be shown on, and the transfer of
that ownership will be effected only through, records maintained by DTC or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants).
Qualified Institutional Buyers may hold their interests in the Restricted Global
Note directly through DTC if they are participants in such system, or indirectly
through organizations which are participants in such system.

  Investors may hold their interests in a Global Note directly through Cedel or
Euroclear, if they are participants in such systems, indirectly through
organizations that are participants in such systems or through organizations
other than Euroclear and Cedel that are participants in the DTC system.  Cedel
and Euroclear will hold interests in a Global Note on behalf of their
participants through DTC.

  So long as DTC, or its nominee, is the registered owner or holder of a Global
Note, DTC or such nominee, as the case may be, will be considered the sole owner
or holder of the Notes represented by such Global Note for all purposes under
the Indenture and the Notes.  In addition, no beneficial owner of an interest in
a Global Note will be able to transfer that interest except in accordance with
DTC's applicable procedures, in addition to those provided for under the
Indenture and, if applicable, those of Euroclear and Cedel.

  Payments of the principal of, and interest on, the Global Notes will be made
to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither the Issuer, the Trustee nor any paying agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Notes
or for maintaining, supervising or reviewing any records relating to such
beneficiary ownership interests.

  The Issuer expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or its nominee.  The Issuer also expects that payments by participants to
owners of beneficial interests in such Global Note held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the names of nominees for such customers.  Such payments will be the
responsibility of such participants.

                                     -103-
<PAGE>
 
  Transfers between participants in DTC will be effected in the ordinary way in
accordance with DTC rules and will be settled in next-day funds.  Transfers
between participants in Euroclear and Cedel will be effected in the ordinary way
in accordance with their respective rules and operating procedures.

  The Issuer understands that DTC will take any action permitted to be taken by
a holder (including the presentation of Notes for exchange) only at the
direction of one or more participants to whose account DTC interests in the
Global Notes is credited and only in respect of such portion of the aggregate
principal amount of Notes as to which such participant or participants has or
have given such direction.  However, if there is an Event of Default under the
Notes, DTC will exchange the Global Notes for Certificated Notes which it will
distribute to its participants.

  The Issuer understands that DTC is a limited purpose trust company organized
under the laws of the State of New York, a "banking organization" within the
meaning of New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the Uniform Commercial Code and a
"Clearing Agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  DTC was created to hold securities for its participants and
facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of
certificates.  Participants include securities brokers and dealers, banks, trust
companies and clearing corporations and certain other organizations.  Indirect
access to the DTC system is available to others such as banks, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").

  Although DTC, Euroclear and Cedel have agreed to the foregoing procedures in
order to facilitate transfers of interests in the Global Notes among
participants of DTC, Euroclear and Cedel, they are under no obligation to
perform or continue to perform such procedures, and such procedures may be
discontinued at any time.  Neither the Issuer, Pierce Leahy nor the Trustee will
have any responsibility for the performance by DTC, Euroclear or Cedel or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.

CERTIFICATED NOTES

  A Global Note is exchangeable for Certificated Notes if (i) the Depository
notifies the Issuer that it is unwilling or unable to continue as a Depository
for such Global Note or if at any time the Depository ceases to be a clearing
agency registered under the Exchange Act and in either case the Issuer thereupon
fails to appoint a successor Depository within 90 days, (ii) the Issuer executes
and delivers to the Trustee a written notice that such Global Note shall be
issuable and transferable in certificated form or (iii) there shall have
occurred and be continuing an Event of Default or an event which, with the
giving of notice or lapse of time or both, would constitute an Event of Default
with respect to the Notes represented by such Global Note. Any Global Note that
is exchangeable for Certificated Notes pursuant to the preceding sentence will
be transferred to, and registered and exchanged for, Certificated Notes in
authorized denominations, without legends applicable to a Global Note but with
the legend referred to under "Notice to Investors" (unless the Issuer determines
otherwise in accordance with applicable law), subject, with respect to such
Notes, to the provisions of such legend, and registered in such names as the
Depository holding such Global Note may direct. Subject to the foregoing, a
Global Note is not exchangeable, except for a Global Note of like denomination
to be registered in the name of the Depository or its nominee. In the event that
a Global Note becomes exchangeable for Certificated Notes, (i) Certificated
Notes will be issued only in fully registered form in denominations of $1,000 or
integral multiples thereof, (ii) payment of principal, any repurchase price, and
interest on the Certificated Notes will be payable, and the transfer of the
Certificated Notes will be registrable, at the office or agency of the Issuer
maintained for such purposes, and (iii) no service charge will be made for any
registration or transfer or exchange of the Certificated Notes, although the
Issuer may require payment of a sum sufficient to cover any tax or governmental
charge imposed in connection therewith.

                 DESCRIPTION OF CAPITAL STOCK OF PIERCE LEAHY

  The authorized capital stock of Pierce Leahy consists of 80,000,000 shares of
Common Stock, par value $.01 per share (the "Common Stock"), and 10,000,000
shares of Preferred Stock, par value $.01 per share (the "Preferred Stock"). As
of August 1, 1998, there were 17,025,990 shares of Common Stock outstanding. No
shares of Preferred Stock are currently outstanding.

COMMON STOCK

  The holders of Common Stock are entitled to one vote per share on each matter
to be decided by the shareholders and do not have cumulative voting rights.
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.  The
holders of Common Stock have no preemptive, redemption or conversion rights.
The holders of Common Stock will be entitled to receive ratably such dividends,
if any, as the Board of Directors may declare from time to time out of funds
legally available for such purpose.  In the event of liquidation, dissolution or
winding up of the affairs of Pierce Leahy, after payment or provision for
payment of all of Pierce Leahy's debts and obligations and any preferential
distributions to holders of Preferred Stock, if any, the holders of the Common
Stock will be entitled to share ratably in Pierce Leahy's remaining assets.  All
outstanding shares of Common Stock are, and the Common Stock offered hereby will
be, validly issued, fully paid and nonassessable.

PREFERRED STOCK

  The Board of Directors is authorized, without further action by the
shareholders, to provide for the issuance of shares of Preferred Stock as a
class without series or in one or more series, to establish the number of shares
in each class or series and to fix the designations, powers, preferences and
rights of each such class or series and the qualifications, limitations or
restrictions thereof.  Because the Board of Directors has the power to establish
the preferences and rights of each class or series of Preferred Stock, the Board
of Directors may afford the holders of any class or series of Preferred Stock
preferences, powers and rights, voting or otherwise, senior to the rights of
holders of Common Stock.  The issuance of Preferred Stock could have the effect
of delaying or preventing a change in control of Pierce Leahy.  As of the date
of this Offering Memorandum, Pierce Leahy has not authorized the issuance of any
Preferred Stock and there are no plans, agreements or understandings for the
issuance of any shares of Preferred Stock.

CERTAIN PROVISIONS OF PENNSYLVANIA LAW AND PIERCE LEAHY'S ARTICLES OF
INCORPORATION AND BYLAWS

  Pierce Leahy is subject to the provisions of Section 2538 and Sections 2551-
2556 of the Pennsylvania Business Corporation Law of 1988, as amended (the
"PBCL"), which in certain cases provide for supermajority shareholder approval
of business combinations involving Pierce Leahy and any "interested shareholder"
(as defined in such statute and 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 Pierce Leahy).  In addition, Sections 2551-
2556 also impose certain restrictions on business combinations involving Pierce
Leahy and any "interested shareholder." The term "business combination" includes
a merger, asset sale or other transaction involving an interested shareholder.

  The PBCL also provides that the directors of a corporation, making decisions
concerning takeovers or any other matters, may consider, to the extent that they
deem appropriate, among other things, (i) the effects of any proposed
transaction upon any or all groups affected by such action, including, among
others, shareholders, employees, suppliers, customers and creditors, (ii) the
short-term and long-term interests of the corporation and (iii) the resources,
intent and conduct of the person seeking control.

  Pierce Leahy's Bylaws provide that its Board of Directors is to be composed of
three classes, with staggered three-year terms, each class to contain as nearly
as possible one-third of the number of members of the Board of Directors.
Accordingly, at each annual meeting of shareholders, only approximately one-
third of Pierce Leahy's directors will be elected.

  Certain other provisions of Pierce Leahy's Articles of Incorporation and
Bylaws could also have the effect of preventing or delaying any change in
control of Pierce Leahy, including (i) the advance notification procedures
governing certain shareholder nominations of candidates for the Board of
Directors and for certain other shareholder business to be conducted at an
annual meeting, (ii) the absence of authority for shareholders to call special
shareholder meetings of Pierce Leahy, except in certain limited circumstances
mandated by the PBCL, and (iii) the absence of authority for shareholder

                                     -105-
<PAGE>
 
action by written consent by less than all of Pierce Leahy's shareholders. These
provisions, the classified board and "supermajority" voting rights, could have
the effect of making it more difficult for a third party to acquire, or
discouraging a third party from seeking to acquire, control of Pierce Leahy.

  As permitted by the PBCL, the Bylaws provide that a director shall not be
personally liable in such capacity 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 the 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 Pierce Leahy's taxes pursuant to local, Pennsylvania or federal
law.  These provisions offer persons who serve on the Board of Directors of
Pierce Leahy protection against awards of monetary damages for negligence in the
performance of their duties.

  The Bylaws also provide that every person who is or was a director or officer
of Pierce Leahy, or a director, officer, employee, agent, partner or fiduciary
of, or in any other capacity for any corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which he served as such at the
request of Pierce Leahy, shall be indemnified by Pierce Leahy to the fullest
extent permitted by law against all expenses and liabilities reasonably incurred
by or imposed upon him, in connection with any proceeding to which he may be
made, or threatened to be made, a party, or in which he may become involved by
reason of his being or having been a director or officer of Pierce Leahy, or a
director, officer, employee, agent, or fiduciary of, or in any other capacity
for such other corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise, whether or not he is a director or officer of Pierce
Leahy or a director, officer, employee, agent, partner or fiduciary of, or in
any other capacity for such other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise at the time the expenses or
liabilities are incurred.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

  The following discussion summarizes certain federal income tax considerations
for holders who elect to substitute their Original Notes for Exchange Notes in
the Exchange Offer.  This summary does not address specific tax aspects of the
Exchange Offer which may be relevant to certain holders such as foreign persons,
financial institutions, broker-dealers, tax-exempt organizations or insurance
companies. THEREFORE, EACH HOLDER OF A NOTE SHOULD CONSULT HIS OR HER OWN TAX
ADVISOR CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF SUBSTITUTING HIS OR HER ORIGINAL NOTES FOR EXCHANGE NOTES IN THE
EXCHANGE OFFER.

  Under current provisions of the Internal Revenue Code of 1986, as amended, the
Treasury Regulations promulgated thereunder and current judicial authority and
administrative rulings and practice, a substitution of the debt instrument of an
issuer for a new debt instrument of the issuer will be treated as an "exchange"
for federal income tax purposes if the new debt instrument differs materially
either in kind or in extent from the old debt instrument. Because the Exchange
Notes are substantially identical to the Original Notes and because the exchange
was contemplated by the Indenture pursuant to which the Original Notes were
sold, the Exchange Notes and Original Notes should not be considered to differ
materially either in kind or in extent and, accordingly, the substitution should
not constitute an "exchange" for federal income tax purposes. Therefore, for
federal income tax purposes, no gain or loss should be recognized by the holder
on the substitution of an Original Note for an Exchange Note, the holder's
adjusted tax basis in the Exchange Note should be the same as his or her basis
in the Original Note and the holding period for the Exchange Note should be the
same as the holding period for the Original Note.

                  CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

  The following is a general summary of the principal Canadian federal income
tax considerations generally applicable to a holder of the Notes or the Exchange
Notes acquired hereunder.  This summary is generally applicable to a holder who,
for purposes of the Income Tax Act (Canada) (the "Act"), holds the Notes and the
Exchange Notes acquired hereunder as capital property, deals at arm's length
with the Issuer and each Canadian Guarantor, is not affiliated with the Issuer
or a Canadian Guarantor, is a non-resident or is deemed to be a non-resident of
Canada for purposes of the Act, is a resident of the United States for purposes
of the Canada-United States Income Tax Convention (1980) (the "Convention"), and
has not and will not use or hold or be deemed to use or hold the Notes or the
Exchange Notes in or in the course of carrying on business in Canada.  This
summary does not apply to a holder that is a "financial institution," as defined
in section 142.2 of the Act, as such definition is proposed to be amended by the
Proposed Tax Amendments (as hereinafter defined).

  This summary is based on the current provisions of the Act, the regulations
thereunder (the "Regulations"), the Convention, counsel's understanding of the
current published administrative and assessing practices of Revenue Canada,
Customs, Excise & Taxation ("Revenue Canada") and on a certificate of an officer
of the Issuer as to certain matters of fact.

  This summary also takes into account all specific proposals to amend the Act
and regulations publicly announced by the Department of Finance of Canada prior
to the date hereof (collectively, the "Proposed Tax Amendments").  No assurances
can be given that the Proposed Tax Amendments will be enacted or will be enacted
as tabled, announced or advised.  Otherwise this summary does not take into
account or anticipate any changes in law, or the administration thereof, whether
by legislative, governmental or administrative action, nor does it take into
account provincial, territorial or foreign income tax legislation or
considerations which may differ significantly from those discussed herein.

  THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR SHOULD
IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR HOLDER OF THE NOTES
OR THE EXCHANGE NOTES.  ACCORDINGLY, PROSPECTIVE INVESTORS SHOULD CONSULT THEIR
OWN TAX ADVISORS WITH RESPECT TO THEIR OWN PARTICULAR CIRCUMSTANCES.

FOREIGN CURRENCY TRANSLATION ISSUES

  Generally, all amounts relevant to the computation of income under the Act
which are payable, paid, receivable, received or expressed in a foreign currency
must be translated into Canadian Dollars using an appropriate exchange rate.  A
holder's cost and proceeds of disposition of a Note or an Exchange Note must be
translated into Canadian Dollars at the date of acquisition and at the date of
disposition, respectively.  Interest on the Notes or the Exchange Notes will
generally be translated into Canadian Dollars at the date on which such interest
is paid or credited.

NOTES AND EXCHANGE NOTES

  In the absence of an exemption under the Act or the Convention, interest paid
or credited by the Issuer to a holder is subject to a non-resident withholding
tax of 25% of the gross amount of the interest under the Act.  The rate of such
withholding tax is reduced by the Convention to 10%.  The Act provides for an
exemption from non-resident withholding tax on interest payable on indebtedness
of the Issuer to a holder who deals at arm's length with the Issuer provided
that the Issuer may not under any circumstances be obliged to pay more than 25%
of the aggregate principal amount of the indebtedness within five years from the
date of issue of the indebtedness, except in the event of a failure or a default
under the terms of the indebtedness or in the case of certain other events
including in the event the terms of the indebtedness become unlawful. Based in
part on a certificate of an officer of the Issuer, amounts of interest paid or
credited by the Issuer on the Notes and the Exchange Notes to holders dealing at
arm's length with the Issuer will not be subject to non-resident withholding
under the Act.

  A holder will not generally be subject to tax under the Act in respect of any
capital gain, or entitled to deduct any capital loss, realized on the
disposition of a Note or an Exchange Note. 

                             PLAN OF DISTRIBUTION

  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes.  This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer in
connection with the resale of Exchange Notes received in exchange for Original
Notes where such Original Notes were acquired as a result of market-making
activities or other trading activities.  The Company has agreed that for a
period of 180 days after the Expiration Date, it will use reasonable efforts to
make this Prospectus, as amended or supplemented, available to any broker-dealer
for use in connection with any such resale; provided that such broker-dealer
indicates in the Letter of Transmittal that it is a broker-dealer.  In addition,
until December 27, 1998, all broker-dealers effecting transactions in the
Exchange Notes may be required to deliver a Prospectus.

  The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers or any other persons.  Exchange Notes received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or at negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such
Exchange Notes. Any broker-dealer that resells Exchange Notes that were received
by it for its own account pursuant to the Exchange Offer and any broker or
dealer that participates in a distribution of such Exchange Notes may be deemed
to be an "underwriter" within the meaning of the Securities Act, and any profit
on any such resale of Exchange Notes and any commissions or concessions received
by any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

  For a period of 180 days after the Expiration Date, the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal.

  By acceptance of this Exchange Offer, each broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer agrees that, upon receipt of
notice form the Company of the happening of any event which makes any statement
in the Prospectus untrue in any material respect or which requires the making of
any changes in the Prospectus in order to make the statements therein not
misleading (which notice the Company agrees to deliver promptly to such broker-
dealer, such broker-dealer will suspend use of the Prospectus until the Company
has amended or supplements the Prospectus to correct such misstatement or
omission and has furnished copies of the amended or supplemented Prospectus to
such broker-dealer.  If the Company gives any such notice to suspend the use of
the Prospectus, it shall extend the 180-day period referred to the above by the
number of days during the period from and including the date of the giving of
such notice up to and including when broker-dealers have received copies of the
supplement or amended Prospectus necessary to permit resales of Exchange Notes.

  The Company has agreed to pay all expenses incident to the Company's
performance of, or compliance with, the Registration Agreement and will
indemnify the holders (including any broker-dealers) and certain parties related
to the holders against certain liabilities, including liabilities under the
Securities Act.

                         INDEPENDENT AUDITOR'S REPORT
                                        
Kestrel Holdings, Inc.
Houston, Texas

We have audited the accompanying balance sheet of Kestrel Holdings, Inc. and
Subsidiaries, as of September 30, 1997, and the related statements of income,
stockholders' equity, and cash flows for the year then ended.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Kestrel Holdings, Inc. and
Subsidiaries, at September 30, 1997, and the results of their operations and
their cash flows for the year then ended in conformity with generally accepted
accounting principles.

_______________________________________________________________________________


 NATURE OF BUSINESS        Kestrel Holdings, Inc. (KHI), through its
                           subsidiaries, provides management, storage, and
                           servicing of client's business records, magnetic
                           media, and technical data, as well as providing
                           consulting services, database development, document
                           imaging and CD-ROM production.

PRINCIPLES OF              The consolidated financial statements include the 
CONSOLIDATION              accounts of KHI and its wholly-owned subsidiaries, 
                           Alpha Welch Properties, Inc., Kestrel Data Management
                           and Storage, Inc. (KDM&S), Kestrel Servicio De
                           Archivos, Inc. (KSAI) and KSAI's 61.25 percent owned
                           subsidiary, Servicio De Archivos, S.A. (SDA). All
                           significant intercompany transactions, profits, and
                           balances have been eliminated.
                            
INTERIM FINANCIAL          The consolidated balance sheet as of June 30, 1998
STATEMENTS                 and the consolidated statements of income for the
                           nine months ended June 30, 1998 and 1997 are
                           unaudited and, in the opinion of management of KHI,
                           include all adjustments (consisting only of normal
                           recurring adjustments) necessary for fair
                           presentation of the results for those interim
                           periods. The results of operations for the nine
                           months ended June 30, 1998 and 1997 are not
                           necessarily indicative of the results to be expected
                           for the full year.
                           
PROPERTY, EQUIPMENT,       Assets are stated at cost.  Depreciation and 
DEPRECIATION, AND          amortization are computed using the straight-line 
 AMORTIZATION              method over the estimated useful lives of the assets.
 
OTHER ASSETS               Costs in excess of the fair value of the assets of
                           acquired businesses totaled $336,029, and are being
                           amortized over 15 and 27 years using the straight-
                           line method. Accumulated amortization at September
                           30, 1997 totaled $103,612.
                           
                           Costs associated with refinancing debt during 1994
                           totaled $218,626, and are being amortized over the
                           life of the associated loans of five and 15 years.
                           Accumulated amortization at September 30, 1997
                           totaled $77,304.
 
ADVANCE RENTALS            Advance rentals billed consists primarily of 
BILLED                     billings to customers, net of amounts amortized into
                           income, at the beginning of their contractual billing
                           periods; monthly, quarterly, semiannually, or
                           annually, which are not refundable.
                            
INCOME TAXES               Deferred income taxes are provided for temporary
                           differences arising from differences between
                           financial statement and income tax bases of assets
                           and liabilities.

USE OF ESTIMATES           The preparation of financial statements in conformity
                           with generally accepted accounting principles
                           requires management to make estimates and assumptions
                           that affect the reported amounts of assets and
                           liabilities and disclosure of contingent assets and
                           liabilities at the date of the financial statements
                           and the reported amounts of revenues and expenses
                           during the reporting period. Actual results could
                           differ from those estimates.

_______________________________________________________________________________

1.  ACQUISITION

    In November 1996, KHI organized Kestrel Servicio De Archivos, Inc. for the
    purpose of purchasing an interest in a records storage and management
    company in Buenos Aires, Argentina. In December 1996, KSAI acquired a 61.25
    percent interest in Servicio De Archivos S.A. The purchase price, $490,000,
    exceeded the fair value of the tangible assets acquired by $213,221, which
    is recorded as goodwill. The goodwill is included in the consolidated
    balance sheets in other assets and is being amortized over the estimated
    life of 15 years. The entire net operating loss of SASA from the date of
    acquisition of $317,000 has been recorded in the consolidated statements of
    income of KHI. None of the loss has been allocated to the 38.75 percent
    minority interest owners because they are not being required to fund their
    portion of the losses.

2.  DISCONTINUED OPERATIONS

    In 1996, two of KHI's subsidiaries, Houston Data Management, Inc. and
    Houston Data Management, Ltd., were merged together and changed their name
    to Kestrel Imaging and Information Management, Inc. (KIIM). KHI transferred
    its ownership in KIIM to KDM&S.

    Effective September 30, 1997, the decision was made to close down the
    operations of KIIM. KIIM was marketing digital image management systems,
    scanning services and CD-ROM conversions. Since the operations of KIIM
    constituted a separate segment, the net losses incurred by KIIM for the year
    are reflected in the financial statements as discontinued operations. The
    net assets of KIIM, which are comprised primarily of computer related
    equipment, have not been segregated in the financial statements because the
    majority of the assets will be retained and used by KDM&S in other lines of
    business.

3.  PROPERTY AND EQUIPMENT

    Data processing equipment includes capitalized software costs with a net
    book value of approximately $491,000 at September 30, 1997. The costs
    include labor and overhead incurred in the development of the software.
    Amortization of the costs using the straight-line method over five years
    totaled approximately $92,350. Because computer software is subject to
    continuing technological changes, it is possible that the software could
    become obsolete, requiring the costs to be written off or amortized more
    rapidly.

     Transactions with related parties are comprised of a long-term payable for
     accrued expenses, which is not expected to be repaid during the next fiscal
     year.

6.   COMMITMENTS AND CONTINGENCIES

     KDM&S leases data center space, automobiles, and equipment under
     noncancelable operating and capital leases expiring 1998 through 2006, and
     other data center space under cancelable or monthly rental agreements. Rent
     expense for all operating leases totaled approximately $1,270,000 during
     the year ended September 30, 1997. Capital leases are included with long-
     term debt and amortization of capitalized costs are included in
     depreciation.

     The following is an analysis of the leased property under capital leases by
     major class:

     Certain data center leases include periods of free or reduced rent payments
     for a period of time and increasing rent payments over the remainder of the
     leases. The Company expenses the total rental obligations using the
     straight-line method over the lease term. At September 30, 1997, the amount
     of rent, which had been expensed but not yet paid, totaled $659,925. The
     future rental payments for operating leases for the year ending September
     30, 1998 of $1,310,000 reflects the actual payments to be made during that
     fiscal year. The actual expense, which will be recorded in the financial
     statements, will be approximately $53,000 higher.

     The Companies located in the United States maintain a 401(k) retirement
     plan whereby eligible employees may contribute up to 15 percent of their
     salary. The Companies contribute 50 cents for every dollar contributed by
     the employees up to three percent of the employees' gross pay. The
     contributions to the Plan by the Companies totaled approximately $35,000
     for the year ended September 30, 1997.

7.   INCOME TAXES

     The financial statements include a deferred income tax liability for the
     differences between financial and tax bases of net assets. Deferred taxes
     result primarily from using a faster rate of depreciation for income tax
     purposes than is used for financial statement purposes.

================================================================================
7.   INCOME TAXES (CONTINUED)

     Income tax expense for the year ended September 30, 1997, is higher than
     the statutory tax rate because a valuation allowance has been recorded for
     the tax benefit, approximately $95,000, from the loss of the Company's
     Argentina subsidiary, KSAI. The loss carryforward of KSAI, approximately
     $317,000, expires in 2002.

     A reconciliation of the income tax expense at the federal statutory rate to
     income tax expense at the effective rate for the year ended September 30,
     1997 is as follows:

          <S>                                                       <C>        
          Income tax expense at the federal statutory rate (34%)    $268,728

8.   DISTRIBUTION OF SUSIDIARY (UNAUDITED)

     Effective in May, 1998, KHI distributed the stock of KSAI to the
     stockholders of KHI. KHI recorded a dividend of $2,238,045, representing
     its basis in KSAI on the date of distribution.
