                           IRON MOUNTAIN INCORPORATED
                      % Senior Subordinated Notes due 2006
   
    The % Senior Subordinated Notes due 2006 (the "Notes") are being offered
(the "Offering") by Iron Mountain Incorporated (the "Company" or "Iron
Mountain"). The net proceeds of the Offering will be used to repay outstanding
bank debt and certain other indebtedness and to fund a portion of the purchase
price of the Pending Acquisition.
    

   Interest on the Notes is payable on             and           , commencing
         , 1997. Except as described below, the Notes are not redeemable by
the Company prior to            , 2001. Thereafter, the Notes are redeemable at 
the option of the Company, in whole or in part, at any time and from time to 
time, at the redemption prices set forth herein plus accrued and unpaid interest
to, but excluding, the date of redemption. In addition, during the first 36 
months after the date of issuance of the Notes, the Company, at its option, may 
redeem up to 35% of the initial principal amount of the Notes with the net 
proceeds of one or more Qualified Equity Offerings at a redemption price equal 
to    %, plus accrued and unpaid interest to, but excluding, the date of 
redemption; provided that at least 65% of the initial principal amount of the
Notes remains outstanding after each such redemption. Except as set forth
herein, the Company is not required to make sinking fund or redemption payments
with respect to the Notes at any time prior to maturity. Upon the occurrence of
a Change of Control, each Holder of Notes may require the Company to repurchase
such Notes at 101% of the principal amount thereof, plus accrued and unpaid
interest to, but excluding, the date of repurchase.

   The Notes will be general unsecured senior subordinated obligations of the
Company ranking junior to all existing and future Senior Debt of the Company.
The Notes will be fully and unconditionally guaranteed on an unsecured senior
subordinated and joint and several basis (the "Subsidiary Guarantees") by
substantially all of the Company's present and future Restricted Subsidiaries
(collectively, the "Guarantors"). The Subsidiary Guarantees will rank junior to
all existing and future Senior Debt of the Guarantors. As of June 30, 1996, on a
pro forma basis after giving effect to the Transactions, the aggregate
outstanding principal amount of Senior Debt of the Company and the Guarantors
would have been $24.5 million.

   The Notes will not be listed on any securities exchange or included in the
National Association of Securities Dealers Automated Quotation System, and there
can be no assurance that there will be a secondary market therefor.

                               PROSPECTUS SUMMARY

   The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and financial statements
appearing elsewhere in this Prospectus. References to "Iron Mountain" and the
"Company" include Iron Mountain Incorporated (including predecessor entities)
and its consolidated subsidiaries, unless the context otherwise requires.

                                   THE COMPANY

   Iron Mountain is the largest records management company in the United States,
as measured by revenues. The Company is a full-service provider of records
management and related services, enabling customers to outsource records
management functions. Pro forma for the Acquisitions (as defined herein), as of
June 30, 1996, the Company managed approximately 29.6 million Cartons* in 103
records centers in 33 markets nationwide. The Company has a diversified base of
over 19,000 customer accounts, which includes more than half of the Fortune 500
and numerous legal, banking, healthcare, accounting, insurance, entertainment
and government organizations. The Company provides storage and related services
for all major media, including paper (which is the dominant form of records
retention and which has accounted for approximately 85% of the Company's
revenues since 1992), computer disks and tapes, microfilm and microfiche, master
audio and video tapes, film and optical disks, X-rays and blueprints. The
Company's principal services include filing, retrieval and destruction of
records, courier pick-up and delivery, database management and customized
reporting. The Company also sells storage materials and provides consulting and
other records-related services.

   The Company continues to capitalize on its leading position in the records
management industry and the industry trends of increased records retention,
outsourcing of records management and vendor consolidation. As a result, the
Company has achieved significant increases in revenues and EBITDA (as defined
herein). From 1991 to 1995, Iron Mountain's total revenues increased from $62.8
million to $104.4 million primarily from internal growth, representing a
compound annual growth rate ("CAGR") of 13.5%. During the same period, storage
revenues grew at a 12.9% CAGR while service and storage material sales revenues
grew at a 14.6% CAGR. From 1991 to 1995, the Company's EBITDA grew from $15.0
million to $26.1 million, representing a 14.9% CAGR. Revenues and EBITDA for the
six months ended June 30, 1996 increased 27.3% (10.2% from internal growth and
17.1% from acquisitions) and 24.8%, respectively, over the same period in 1995.
For a discussion of the significance of EBITDA and other measures of the
Company's performance determined in accordance with generally accepted
accounting principles ("GAAP") and the Company's sources and applications of
cash flow, see "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Overview" and "--Liquidity and Capital Resources."

Industry Overview

   According to industry sources, organizations in the United States generate an
estimated four trillion documents each year, many of which must be retained and
remain available for reference for many years. These records may be generally
divided into two categories: active and inactive. Inactive records, which are
the principal focus of the records management industry, consist of records that
are not needed for immediate access but which must be retained for legal or
regulatory reasons or for occasional reference to support ongoing business
operations. Based on industry studies, the Company believes that inactive
records make up approximately 80% of all records. The Company believes that the
volume of inactive records is increasing for a number of reasons, including: (i)
the rapid growth of inexpensive document producing technologies such as
facsimile, desktop printing and computer networking; (ii) increased regulatory
requirements; (iii) concerns over possible future litigation and the resulting
increases in volume and holding periods of documentation; (iv) the high cost of
reviewing records and deciding whether to retain or destroy them; and (v) the
failure of many entities to adopt or follow policies on records destruction.
Despite the growth of new "paperless" technologies, such as the Internet and
e-mail, management believes that stored information remains predominantly
paper-based and that such technologies have promoted the creation of hard copies
of such electronic information.

- -------------
* The term "Carton" is defined as a measurement of volume equal to a single
standard storage carton, approximately 1.2 cubic feet. The number of Cartons
stored does not include storage volumes in the Company's vital records services
and data protection services, which are described under "Business."

                                      3


   The Company believes that it benefits from several industry fundamentals,
including: (i) the historically non- cyclical nature of the records management
industry; (ii) the continued trend towards corporate outsourcing of records
management functions; (iii) the ability of larger records management companies
to achieve economies of scale with respect to labor, real estate costs and the
utilization of management information systems; and (iv) the ongoing
consolidation of the records management industry.

   The Company believes that it is one of only four records management providers
with a national operating presence, the balance being regional or, in most
instances, single-city operators. According to the Association of Commercial
Records Centers (the "ACRC"), a trade group of approximately 500 members, as of
January 1994 (the latest date for which such information is available),
approximately 2,600 firms offered records storage and management services in the
United States. The Company believes that there is a trend toward consolidation
in the records management industry and that such trend will continue to
accelerate primarily because of: (i) the opportunities to achieve economies of
scale; (ii) the industry's capital requirements for growth; (iii) customer
demands for more sophisticated technology-based solutions; and (iv) the
preference of certain large, national customers to outsource a significant
portion of their records management functions to one vendor with a national
presence, such as Iron Mountain.

Financial Characteristics of Iron Mountain's Business

   Iron Mountain's records management business has the following financial
characteristics:

   (bullet)Recurring Revenues. Iron Mountain derives a majority of its revenues
           from fixed periodic (usually monthly) fees charged to customers for
           storage of records. Storage revenues have grown for 30 consecutive
           quarters and have represented approximately 60% of the Company's
           total revenues in each of the last five years. Once a customer places
           a record in storage with the Company and until that record is
           destroyed or permanently removed (for which the Company typically
           receives a service fee), the Company receives recurring payments of
           fixed periodic fees without incurring additional labor or marketing
           expenses or significant capital costs. The stable and growing storage
           base also provides the foundation for increases in revenues and
           EBITDA from service activities and sales of storage materials.

   (bullet)Historically Non-Cyclical Business. Iron Mountain has not experienced
           a reduction of its business as a result of past general economic
           downturns, although there can be no assurance that this would be the
           case in the future. Management believes that the outsourcing of
           records management may accelerate during economic downturns as
           companies focus on reducing costs through outsourcing non-core
           operating functions. In addition, management believes that companies
           that have outsourced records management are less likely during
           economic downturns to incur the move-out costs and other expenses
           associated with switching vendors or moving records management
           in-house.

   (bullet)Inherent Growth from Existing Customers. The Company's customers have
           on average generated additional Cartons at a faster rate than stored
           Cartons have been destroyed or permanently removed. From 1992 to
           1995, net Cartons from existing customers grew at an average annual
           rate of 6.7%. The Company believes the consistent growth of its
           storage revenues is the result of a number of additional factors,
           including: (i) the trend toward increased records retention; (ii)
           customer satisfaction with the Company's services; and (iii) the
           costs and inconvenience of moving storage operations in-house or to
           another provider of records management services.

   (bullet)Diversified and Stable Customer Base. The Company has over 19,000
           customer accounts in a variety of industries. The Company currently
           provides services to more than half of the Fortune 500 and numerous
           legal, banking, healthcare, accounting, insurance, entertainment and
           government organizations. Only one of the Company's customers
           accounted for more than 3% of revenues in 1993, 1994 or 1995. From
           1992 to 1995, average annual permanent removals of Cartons
           represented only approximately 4% of total Cartons stored.

   (bullet)Capital Expenditures Related Primarily to Growth. The Company's
           business requires limited annual maintenance capital expenditures.
           Maintenance capital expenditures were $1.8 million, $1.2 million and
           $0.9 million in 1993, 1994 and 1995, respectively. From 1992 to 1995,
           over 90% of the Company's aggregate capital expenditures were
           growth-related investments, primarily in racking systems, new

                                      4


           buildings and leasehold improvements, equipment for new facilities,
           management information systems and facilities restructuring. These
           growth-related capital expenditures are primarily discretionary and
           create additional capacity for increases in revenues and EBITDA.

Business Strategy

   Iron Mountain's business strategy is to increase revenues and EBITDA while
maintaining a low-cost operating structure and providing premium service. The
Company intends to generate growth by increasing its storage and service
revenues from existing customers, adding new customers and making acquisitions.
The Company's strategy is based on the following elements:

   (bullet)Provide Superior Customer Service. The Company believes it has a
           reputation for providing reliable, quality service based on its more
           than 45 years of operations, its commitment to providing premium
           customer service and the continuity and depth of its management team.
           The Company has successfully implemented a decentralized management
           structure that enables the Company to respond quickly and flexibly to
           local customer needs. Iron Mountain's proprietary Safekeeper(R)
           system enables it to quickly provide customized records management
           solutions to its customers, enhancing the quality of its services. In
           addition, Iron Mountain's national operating presence allows it to
           better service large organizations that require records management
           functions at multiple, geographically diverse facilities.

   (bullet)Capitalize on Operating Efficiencies. Iron Mountain pursues a
           low-cost operating strategy based primarily on achieving economies of
           scale in the areas of storage, labor and transportation, general and
           administrative functions and management information systems. Because
           occupancy costs are a major component of the Company's cost of sales,
           its real estate management staff aggressively seeks to minimize per
           Carton storage costs by designing racking systems and operating space
           to maximize facility storage efficiency, negotiating favorable
           facility leases, contracting for facilities to be built to its custom
           specifications, and leasing larger facilities in order to reduce
           operating costs per Carton. The Company seeks to increase labor
           efficiency by offering incentive compensation to all full-time
           employees based upon achieving specific operating targets. Certain
           operating costs, such as the maintenance of local delivery fleets,
           general and administrative costs and management information systems,
           offer economies of scale, providing the Company with operating
           leverage and the ability to increase its efficiency through further
           growth.

   
   (bullet)Pursue Acquisition Opportunities. The Company believes that it is
           well positioned to participate in the further consolidation of the
           records management industry. Iron Mountain's management team has
           successfully completed 18 acquisitions since the Company embarked on
           a proactive acquisition strategy in mid-1994, and one additional
           acquisition is currently pending. The Company intends to continue to
           make fold-in acquisitions to augment its operations in existing
           markets and to make strategic acquisitions in new geographic markets,
           with an emphasis on the 50 largest markets in the United States and
           potentially in certain markets outside the United States. Following
           an acquisition in a new market, the Company seeks to increase its
           business with the acquired customer base and to supplement that
           growth both with new customers and through appropriate fold-in
           acquisitions. In addition, the Company has successfully reduced the
           cost structure of its acquired operations by implementing its
           efficient operating strategies and leveraging its centralized
           administrative resources and management information systems.
    

   (bullet)Leverage Proprietary Safekeeper System. The Company pioneered the
           application of advanced information technology to the records
           management industry. Iron Mountain's proprietary Safekeeper system
           provides advanced inventory control and information access, enabling
           the Company to provide faster, higher quality and more flexible
           solutions to its customers and to lower the costs of its operations.
           Safekeeper has been designed to easily and effectively integrate
           newly acquired records management companies and offer improved levels
           of customer service and records management capabilities to customers
           acquired through acquisitions. Iron Mountain's Safekeeper system
           exploits bar-code technology to provide a comprehensive, standardized
           approach to tracking, accessing and retrieving records. Safekeeper
           offers state-of-the-art records management capabilities and ease of
           access to customers while featuring security functions to protect
           customer information from unauthorized access. Since 1992, the
           Company has invested $12.5 million to develop and refine its

                                  THE OFFERING



                            
Securities Offered             $150,000,000 principal amount of     % Senior Subordinated Notes due 2006
                               (the "Notes").

Maturity Date                                  , 2006

Interest Payment Dates                     and             of each year, commencing
                                               , 1997.

   
Guarantees                     The Notes will be fully and unconditionally guaranteed on an unsecured senior
                               subordinated and joint and several basis (the "Subsidiary Guarantees") by
                               substantially all of the Company's present and future Restricted Subsidiaries
                               (collectively, the "Guarantors"). Each of the Guarantors has also guaranteed
                               unconditionally the indebtedness outstanding under the Company's existing
                               bank credit facility (the "Credit Agreement") and will guarantee
                               unconditionally the indebtedness outstanding under the new bank credit
                               facility the Company intends to enter into with its lenders (the "New
                               Credit Facility"). See "Description of the Notes--Subsidiary Guarantees."
    

Subordination                  The Notes will be general unsecured senior subordinated obligations of the
                               Company ranking junior to all existing and future Senior Debt of the Company,
                               including any indebtedness that may be incurred under the Credit Agreement or
                               the New Credit Facility. The Subsidiary Guarantees will rank junior to all
                               existing and future Senior Debt of the Guarantors. As of June 30, 1996, on a
                               pro forma basis after giving effect to the Transactions, the aggregate
                               outstanding principal amount of Senior Debt of the Company and the Guarantors
                               would have been $24.5 million. See "Description of the Notes--Subordination."

Optional Redemption            Except as described below, the Notes are not redeemable by the Company prior
                               to          , 2001. Thereafter, the Notes are redeemable at the option of the
                               Company, in whole or in part, at any time and from time to time, at the
                               redemption prices set forth herein plus accrued and unpaid interest to, but
                               excluding, the date of redemption. In addition, during the first 36 months
                               after the date of issuance of the Notes, the Company, at its option, may
                               redeem up to 35% of the initial principal amount of the Notes with the net
                               proceeds of one or more Qualified Equity Offerings at a redemption price
                               equal to      %, plus accrued and unpaid interest to, but excluding, the date
                               of redemption; provided that at least 65% of the initial principal amount of
                               the Notes remains outstanding after each such redemption. See "Description of
                               the Notes--Optional Redemption."

Mandatory Redemption           Except with respect to required repurchases upon the occurrence of a Change
                               of Control or in the event of certain Asset Sales, the Company is not
                               required to make sinking fund or redemption payments with respect to the
                               Notes at any time prior to maturity. See "Description of the Notes--
                               Mandatory Redemption."

                                      6


Change of Control              Upon the occurrence of a Change of Control, each Holder of Notes may require the
                               Company to repurchase such Notes at 101% of the principal amount thereof, plus 
                               accrued and unpaid interest to, but excluding, the date of repurchase. See 
                               "Description of the Notes--Repurchase at the Option of Holders--Change of Control."

Certain Covenants              The Indenture governing the Notes (the "Indenture") will contain covenants
                               restricting or limiting the ability of the Company and its Restricted
                               Subsidiaries to, among other things: (i) incur additional indebtedness,
                               including indebtedness ranking senior to the Notes and junior to any Senior
                               Debt; (ii) pay dividends or make other restricted payments; (iii) make asset
                               dispositions; (iv) permit liens; (v) enter into sale and leaseback
                               transactions; (vi) enter into certain mergers; (vii) make certain
                               investments; and (viii) enter into transactions with related persons. See
                               "Description of the Notes--Certain Covenants."

Use of Proceeds                The net proceeds of the Offering will be used to repay outstanding bank debt and
                               certain other indebtedness and to fund a portion of the purchase price of the 
                               Pending Acquisition.

(1) Gives effect to: (i) the Completed Acquisitions (as defined herein); (ii)
    the Pending Acquisition (as defined herein); (iii) the consummation of the
    Company's initial public offering of its Common Stock, par value $0.01 per
    share (the "Common Stock"), which closed on February 6, 1996 (the "Initial
    Public Offering") and the application of the net proceeds therefrom; (iv)
    the closing under the New Credit Facility; and (v) the application of the
    estimated net proceeds from the Offering, as if each had occurred as of
    January 1, 1995. The Company will record, in the quarter in which the
    Offering is consummated, an extraordinary loss on retirement of debt, net of
    related tax benefit. As of June 30, 1996, the amount of such loss would have
    been approximately $2.2 million. The pro forma statements of operations data
    do not give effect to such loss. See "The Transactions," "Use of Proceeds"
    and "Pro Forma Condensed Consolidated Financial Information."
    

(2) Earnings before interest, taxes, depreciation, amortization and
    extraordinary charges ("EBITDA"). Based on its experience in the records
    management industry, the Company believes that EBITDA is an important tool
    for measuring the performance of records management companies (including
    potential acquisition targets) in several areas, such as liquidity,
    operating performance and leverage. In addition, lenders use EBITDA as a
    criterion in evaluating records management companies, and substantially all
    of the Company's financing agreements contain covenants in which EBITDA is
    used as a measure of financial performance. However, EBITDA should not be
    considered an alternative to operating or net income (as determined in
    accordance with 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. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Overview" and "--Liquidity and Capital
    Resources" for discussions of other measures of performance determined in
    accordance with GAAP and the Company's sources and applications of cash
    flow.

(3) Growth capital expenditures include investments in racking systems, new
    buildings and leasehold improvements, equipment for new facilities,
    management information systems and facilities restructuring. See
    "Management's Discussion and Analysis of Financial Condition and Results
    of Operations--Liquidity and Capital Resources--Capital Investments."

(4) Includes $2,901 related to the cost of constructing a records management
    facility which was sold in a sale and leaseback transaction in the fourth
    quarter of 1994.

(5) The term "Carton" is defined as a measurement of the volume equal to a
    single standard storage carton, approximately 1.2 cubic feet. The number of
    Cartons stored does not include storage volumes in the Company's vital
    records services and data protection services which are described under
    "Business." Pro forma Carton information for 1995 is not available.

   
(6) Gives effect to (i) the Completed Acquisitions completed after June 30, 1996
    and (ii) the Pending Acquisition. Adjusted EBITDA, as defined in the
    Indenture, equals the sum of (i) EBITDA of the Company and the Restricted
    Subsidiaries for the most recent fiscal quarter for which internal financial
    statements are available, multiplied by four, plus (ii) Acquisition EBITDA
    of each business that has been acquired by the Company since the beginning
    of such quarter (including any such acquisition which is occurring on the
    date of the calculation), multiplied by a fraction, (a) the numerator of
    which is three minus the number of months (and/or any portion thereof) in
    such quarter for which the financial results of such acquired business are
    included in the EBITDA of the Company and its Restricted Subsidiaries under
    clause (i) above, and (b) the denominator of which is three. In addition,
    the effects of unusual or non-recurring items occurring in any relevant
    period shall be excluded in the calculation of Adjusted EBITDA. With respect
    to any such acquired business, Acquisition EBITDA equals the sum of (i)
    EBITDA of such acquired business for its last fiscal quarter for which
    financial statements are available, multiplied by four (or if such quarterly
    statements are not available, EBITDA for the last fiscal year for which
    financial statements are available), plus (ii) projected quantifiable
    improvements in operating results (on an annualized basis) due to cost
    reductions calculated in good faith by the Company or one of its Restricted
    Subsidiaries, as certified by an Officers' Certificate filed with the
    Trustee, without giving effect to any operating losses of the acquired
    business. Such projected quantifiable savings may differ from the cost
    savings used to calculate the Pro Forma Condensed Consolidated Statement of
    Operations. Adjusted EBITDA is merely a calculation utilized for purposes of
    debt incurrence under the Indenture and should not be viewed as indicative
    of actual or future results.
    

(7) Cash interest expense represents total interest expense less amortization of
    deferred financing costs and other non-cash interest charges for the twelve
    months ended June 30, 1996 on a pro forma basis giving effect to the
    Transactions (as defined herein) as if each had occurred on July 1, 1995.
    The calculation of cash interest expense assumes an interest rate of 10-1/2%
    on the Notes.

(8) Net debt represents total debt less cash and cash equivalents and was
    calculated based on the pro forma net debt as of June 30, 1996 of $172.3
    million.

   
(9) Gives effect to: (i) the Completed Acquisitions consummated after June
    30, 1996; (ii) the Pending Acquisition; (iii) the closing under the New
    Credit Facility; and (iv) the application of the net proceeds from the
    Offering, as if each had occurred as of June 30, 1996. See "The 
    Transactions," "Use of Proceeds" and "Pro Forma Condensed Consolidated
    Financial Information."

                                  RISK FACTORS

   
   Prospective investors should carefully consider the following risk factors,
in addition to the other information contained in this Prospectus, in connection
with an investment in the Notes offered hereby. Certain statements contained
under "Management's Discussion and Analysis of Financial Condition and Results
of Operations," such as those regarding the goals, beliefs or current
expectations of the Company and its management with respect to, among other
things, revenue growth and future capital needs, and other statements contained
in this Prospectus regarding matters that are not historical facts are
forward-looking statements (as such term is defined in the rules promulgated
pursuant to the Securities Act of 1933, as amended). Because such
forward-looking statements include risks and uncertainties, actual results may
differ materially from those expressed in or implied by such forward- looking
statements. Factors that could cause actual results to differ materially
include, but are not limited to, those discussed herein under "Risk Factors."
The Company undertakes no obligation to release publicly the result of any
revisions to these forward-looking statements that may be made to reflect events
or circumstances after the date hereof or to reflect the occurrence of
unanticipated events. 
    

   Financial Leverage; Debt Service Requirements. The Company is highly
leveraged due to the substantial indebtedness it has incurred primarily to
finance acquisitions and expand its operations. As of June 30, 1996, on a pro
forma basis, after giving effect to the Transactions, the Company would have had
$174.5 million in total indebtedness and $52.5 million in stockholders' equity.
The Company expects to continue to borrow under the New Credit Facility and
possible future credit arrangements in order to finance possible future
acquisitions and for general corporate purposes.

   The ability of the Company to repay the Notes and its other indebtedness will
depend upon future operating performance, which is subject to the success of the
Company's business strategy, prevailing economic conditions, levels of interest
rates and financial, business and other factors, many of which are beyond the
Company's control. The debt service obligations of the Company could have
important consequences, including the following: (i) the ability of the Company
to obtain additional financing for future working capital needs or for possible
future acquisitions or other purposes may be limited; (ii) a substantial portion
of the Company's cash flow from operations will be dedicated to the payment of
principal and interest on its indebtedness, thereby reducing funds available for
other purposes; (iii) the Company may be more vulnerable to adverse economic
conditions than some of its competitors and thus may be limited in its ability
to withstand competitive pressures; and (iv) the Company may be more highly
leveraged than certain of its competitors, which may place it at a competitive
disadvantage.

   A substantial portion of the Company's cash flow from operations is required
for debt service. Management believes that cash flow from operations in
conjunction with borrowings from existing and possible future credit facilities
will be sufficient for the foreseeable future to meet debt service requirements
and to make possible future acquisitions and capital expenditures. However,
there can be no assurance in this regard, and the Company's leverage could make
it vulnerable to a downturn in the operating performance of its subsidiaries, a
downturn in economic conditions or, because borrowings under the New Credit
Facility will bear interest at rates which fluctuate, increases in interest
rates on borrowings under the New Credit Facility. If such cash flow were not
sufficient to meet such debt service requirements or payments of principal, the
Company could be required to sell additional equity securities, refinance its
obligations or dispose of assets in order to make such scheduled payments. There
can be no assurance that the Company would be able to effect any of such
transactions or do so on favorable terms.

   Subordination; Guarantees. The Notes will be unsecured senior subordinated
obligations of the Company and will be subordinated in right of payment to the
prior payment in full of all existing and future Senior Debt of the Company. At
June 30, 1996, the Company had $103.6 million of indebtedness outstanding that
would have constituted Senior Debt. On a pro forma basis, after giving effect to
the Transactions, the Company would have had $24.5 million of Senior Debt
outstanding. The Company intends to actively pursue additional acquisitions
which would likely be financed through the incurrence of additional
indebtedness. Such additional indebtedness may constitute Senior Debt. The
Indenture allows the Company to incur Senior Debt from time to time under the
New Credit Facility or otherwise, subject to certain limitations. Upon any
acceleration of the maturity of the Notes or upon any payment or distribution of
assets of the Company to creditors upon any liquidation, dissolution, winding-
up, reorganization, assignment for the benefit of creditors, marshaling of
assets or any bankruptcy, insolvency or similar proceedings of the Company, the
holders of all Senior Debt will be first entitled to receive payment in full of
all amounts due or to become due thereon before the Holders of Notes will be
entitled to receive any payment in respect of the principal of or premium, if
any, or interest on the Notes. In addition, upon the occurrence of a

                                      10


payment default or certain other defaults in respect of outstanding Senior
Debt, Holders of Notes may be prevented from receiving payments with respect
to the Notes for an extended period. See "Description of the Notes--
Subordination."

   
   Iron Mountain's subsidiaries have guaranteed on a senior subordinated basis
its obligations under the Credit Agreement and will guarantee its obligations
under the New Credit Facility. Iron Mountain's obligations under the Credit
Agreement are secured by a first priority security interest in substantially all
of its assets (including the stock of its subsidiaries). Iron Mountain's
obligations under the New Credit Facility will be secured by a pledge of the
stock of its subsidiaries. If Iron Mountain becomes insolvent or is liquidated
or if the indebtedness under the Credit Agreement or the New Credit Facility is
accelerated, the lenders under the Credit Agreement or the New Credit Facility
would be entitled to exercise the remedies available to a secured lender.
Accordingly, such lenders will have a prior claim on such assets of Iron
Mountain and its subsidiaries. In such event, it is possible that there would be
no assets remaining from which claims of the Holders of Notes could be satisfied
or, if any assets remained, such assets might be insufficient to fully satisfy
such claims. The Company may incur additional secured indebtedness in the
future. See "Description of the Notes--Certain Covenants--Incurrence of
Indebtedness and Issuance of Preferred Stock" and "--Liens." 
    

   Iron Mountain is a holding company, substantially all of the assets of which
are the stock of its subsidiaries. Substantially all of the operations of the
Company are currently conducted by Iron Mountain's direct and indirect wholly
owned subsidiaries, all of which will be Guarantors, subject to the terms of the
Indenture. Management of the Company believes that separate financial statements
of such subsidiaries are not meaningful or material to investors and therefore
such statements have not been included in this Prospectus. The Company does not
currently expect that it will be required to prepare separate financial
statements for any of its subsidiaries in the foreseeable future and does not
expect to do so.

   Unenforceability and Release of Guarantees. Iron Mountain's obligations under
the Notes will be guaranteed, jointly and severally, on a senior subordinated
basis by the Guarantors. To the extent that a court were to find that (i) a
Subsidiary Guarantee was incurred by a Guarantor with intent to hinder, delay or
defraud any present or future creditor or the Guarantor contemplated insolvency
with a design to prefer one or more creditors to the exclusion in whole or in
part of others, or (ii) such Guarantor did not receive fair consideration or
reasonably equivalent value for issuing its Subsidiary Guarantee and such
Guarantor (a) was insolvent; (b) was rendered insolvent by reason of the
issuance of such Subsidiary Guarantee; (c) was engaged or about to engage in a
business or transaction for which the remaining assets of such Guarantor
constituted unreasonably small capital to carry on its business; (d) intended to
incur, or believed that it would incur, debts beyond its ability to pay such
debts as they mature; or (e) was a defendant in an action for money damages or
had a judgment for money damages docketed against it (if, in either case, after
final judgment, the judgment is unsatisfied), then in each such case, a court
could avoid or subordinate such Subsidiary Guarantee in favor of the Guarantor's
other creditors. The measure of insolvency for purposes of the foregoing will
vary depending upon the law of the jurisdiction which is being applied.
Generally, however, a company will be considered insolvent for purposes of the
foregoing if, at the time it incurs any given obligation, the sum of the
company's debts (including unliquidated or contingent debt) is greater than all
the company's property at a fair valuation, or if the present fair salable value
of the company's assets is less than the amount that will be required to pay its
probable liability on its existing debts (including unliquidated or contingent
debt) as they become absolute and matured.

   To the extent any Subsidiary Guarantee were to be avoided as a fraudulent
conveyance or held unenforceable for any other reason, Holders of Notes would
cease to have any claim in respect of such Guarantor and would be creditors
solely of the Company and any Guarantor whose Subsidiary Guarantee was not
avoided or held unenforceable. In such event, the claims of the Holders of Notes
against the issuer of an invalid Subsidiary Guarantee would be subject to the
prior payment of all liabilities of such Guarantor, including without
limitation, to the extent valid and enforceable, such Guarantor's guarantee of
indebtedness of Iron Mountain under the Credit Agreement or the New Credit
Facility, as the case may be, and any other Senior Debt of Iron Mountain
guaranteed by such Guarantor. There can be no assurance that, after providing
for all prior claims, there would be sufficient assets to satisfy the claims of
the Holders of Notes relating to any voided Subsidiary Guarantee. See
"Description of the Notes--Subordination."

   Based upon financial and other information currently available to it, the
Company believes that the Notes and the Subsidiary Guarantees are being incurred
for proper purposes and in good faith, and that the Company and each Guarantor

                                      11


are solvent and will continue to be solvent after issuing the Notes or the
Subsidiary Guarantees, as the case may be, will have sufficient capital for
carrying on their businesses after such issuance and will be able to pay their
debts as they mature. There can be no assurance, however, that a court would
reach the same conclusion.

   Any Guarantor may be released from its Subsidiary Guarantee at any time upon
any sale, exchange or transfer in compliance with the provisions of the
Indenture by the Company of the capital stock of such Guarantor or substantially
all of the assets of such Guarantor and, in certain other circumstances, a
Guarantor may be released from its Subsidiary Guarantee in connection with the
Company's designation of such Guarantor as an Unrestricted Subsidiary. See
"Description of the Notes--Certain Covenants--Additional Subsidiary Guarantees."

   
   Restrictions Imposed by Terms of Indebtedness. The Indenture will contain
covenants restricting or limiting the ability of the Company and its Restricted
Subsidiaries to, among other things: (i) incur additional indebtedness,
including indebtedness ranking senior to the Notes and junior to any Senior
Debt; (ii) pay dividends or make other restricted payments; (iii) make asset
dispositions; (iv) permit liens; (v) enter into sale and leaseback transactions;
(vi) enter into certain mergers; (vii) make certain investments; and (viii)
enter into transactions with related persons. In addition, the Credit Agreement
contains, and the New Credit Facility will contain, certain other and more
restrictive covenants than those contained in the Indenture. See "Description of
New Credit Facility." This may adversely affect the Company's ability to pursue
its acquisition strategy. The Credit Agreement also requires, and the New Credit
Facility will require, the Company to maintain specific financial ratios and to
satisfy certain financial condition tests. The Company's ability to meet those
financial ratios and financial condition tests can be affected by events beyond
its control, and there can be no assurance that the Company will meet those
tests. The breach of any of those covenants could result in a default under the
New Credit Facility, the Indenture or both. In the event of a default under the
New Credit Facility or the Indenture, the lenders could seek to declare all
amounts outstanding under the New Credit Facility, together with accrued and
unpaid interest, if any, to be immediately due and payable. If the Company were
unable to repay those amounts, the lenders under the New Credit Facility could
proceed against the collateral granted to them to secure that indebtedness. If
the indebtedness under the New Credit Facility or the Notes were to be
accelerated, there can be no assurance that the assets of the Company would be
sufficient to repay in full that indebtedness and the other indebtedness of the
Company. The Notes are subordinated to all existing and future Senior Debt of
the Company, including indebtedness under the Credit Agreement or the New Credit
Facility, as the case may be, and the Guarantees are subordinated to all
existing and future Senior Debt of the Guarantors, including guarantees by the
Guarantors of the indebtedness outstanding under the Credit Agreement or the New
Credit Facility, as the case may be. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources." 
    

   Holding Company Structure; Dependence Upon Operations of Subsidiaries.
Substantially all of the tangible assets of the Company are held by, and
substantially all of the Company's operating revenues are derived from
operations of, the Company's subsidiaries. Therefore, the Company's ability to
pay interest and principal when due to Holders of Notes will be dependent upon
the receipt of sufficient funds from such subsidiaries. However, the Company's
obligations under the Notes will be guaranteed, jointly and severally, on a
senior subordinated basis, by substantially all of the Company's present and
future Restricted Subsidiaries.

   Risk of Inability to Finance Change of Control Offer. In the event of a
Change of Control, the Company will be required to offer to purchase all Notes
then outstanding at a purchase price, in cash, equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the date of
purchase. There can be no assurance that the Company would be able to obtain
such funds through a refinancing of the Notes to be purchased or otherwise, or
that the purchase would be permitted under the Credit Agreement, the New Credit
Facility or the terms of other financing instruments, as the case may be. Also,
the requirement that the Company offer to purchase all Notes then outstanding in
the event of a Change of Control may have the effect of deterring a third party
from effecting a transaction that would constitute a Change of Control. See
"Description of the Notes--Repurchase at the Option of Holders--Change of
Control."

   Absence of Public Market for the Notes. There is no public market for the
Notes. The Notes will not be listed on any securities exchange or included in
the National Association of Securities Dealers Automated Quotation System. The
Company has been advised by the Underwriters that, following the completion of
the Offering, the Underwriters presently intend to make a market in the Notes;
however, they are under no obligation to do so and may discontinue any
market-making activities at any time without notice. No assurance can be given
as to the liquidity of the trading market for the Notes or that an active public
market will develop or, if developed, will

                                      12


continue. If an active public market does not develop or is not maintained,
the market price and liquidity of the Notes may be adversely affected. See
"Underwriting."

   
   Risks Associated with Acquisition Strategy. The Company has pursued and
intends to continue to pursue acquisitions of records management businesses as a
key component of its growth strategy. Since mid-1994, the Company has acquired
or entered into agreements to acquire 19 companies (of which 18 have been
completed and one is pending) engaged in the records management and related
businesses for estimated cash purchase prices aggregating $103.2 million (not
including contingent payments of up to $4.6 million based upon the achievement
of certain revenue targets from 1996 through 1998). See "The Transactions" and
"Recent and Pending Acquisitions." Possible future acquisitions may be for
purchase prices significantly larger than those paid for acquisitions
consummated since mid-1994. Certain risks are inherent in an acquisition
strategy, such as increasing leverage and debt service requirements and
combining disparate company cultures and facilities, which could adversely
affect the Company's operating results. The success of any completed acquisition
will depend in part on Iron Mountain's ability to integrate effectively the
acquired records management business into the Company. The process of
integrating such acquired businesses may involve unforeseen difficulties and may
require a disproportionate amount of management's attention and the Company's
financial and other resources. No assurance can be given that the Pending
Acquisition will be completed, that additional suitable acquisition candidates
will be identified, financed and purchased on acceptable terms, or that recent
acquisitions or future acquisitions, if completed, will be successful. See
"Business--Growth Strategy--Growth through Acquisitions." 
    

   Acquisitions by the Company in excess of $25 million individually and $50
million in the aggregate per year will require the approval of the majority
lenders under the Credit Agreement, and the New Credit Facility will contain
similar or other restrictions on acquisitions. No assurance can be given that
the lenders will consent to any acquisitions that the Company proposes to make
in excess of such limits.

   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 the results
that may be achieved for any subsequent fiscal quarter or for a full fiscal
year.

   Competition; Alternative Technologies. The Company faces competition from one
or more competitors in all geographic areas where 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. As a result of
this competition, the records management industry has for the past several years
experienced downward pricing pressures. While Iron Mountain believes that this
pricing climate is stabilizing, there can be no assurance that prices will not
decline further, as competitors seek to gain or preserve market share. 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 may possess greater financial and other resources than the
Company. If any such competitor were to devote additional resources to the
records management business and such acquisition candidates or to focus its
strategy on the Company's markets, the Company's results of operations could be
adversely affected. In addition, the Company 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."

   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 include
computer media, microforms, audio/video tape, film, CD-ROM and optical disk.
None of these technologies has replaced paper as the principal means for storing
information. 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.

   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

                                      13


   
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,
such as losses from earthquakes, or may be altogether uninsurable, such as
losses from riots. In addition, as of June 30, 1996, 24 of the Company's 89
records management facilities were located in California and the Company derived
approximately 30% of its revenues for the six months ended June 30, 1996 from
its operations in California. The Company has in the past suffered damages and
losses from an earthquake and a riot in California, which damages and losses
were substantially covered by insurance. In the future, should uninsured losses
or damages occur, the Company could lose both its investment in and anticipated
profits and cash flow 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 loss could
materially adversely affect the Company. See "Business--Insurance." 
    

   Environmental Matters. As of June 30, 1996, the Company owned or leased
approximately 6.3 million square feet of facilities. Under various federal,
state and local environmental laws, ordinances and regulations ("environmental
laws"), an owner of real estate or a lessee conducting operations thereon may
become liable for the costs of investigation, removal or remediation of soil and
groundwater contaminated by certain hazardous substances or wastes or petroleum
products. Certain such laws impose cleanup responsibility and liability without
regard to whether the owner or operator of the real estate or operations 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 substances, or the failure to
properly remediate such property, may adversely affect the current property
owner's or operator's ability to sell or rent such property or to borrow using
such property as collateral. The owner or operator of contaminated real estate
also may be subject to common law claims by third parties based on 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"). Such laws may impose liability for
release of ACMs and may enable third parties to seek recovery from owners or
operators of real estate for personal injury associated with exposure to such
substances. Certain facilities operated by the Company contain or may contain
ACMs. In addition, 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 substances or petroleum products
or the generation and disposal of hazardous wastes, and in some instances,
included the operation of underground storage tanks ("USTs").

   In connection with its former and current ownership or operation of certain
properties, the Company may be potentially liable for environmental costs such
as those discussed above and as more specifically described under
"Business--Environmental Matters." The Company has from time to time conducted
certain environmental investigations and remedial activities at certain of its
former and current facilities, but an in-depth environmental review of the
properties has not been conducted by or on behalf of the Company.

   The Company believes it is in substantial compliance with all applicable
material environmental laws. 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 noncompliance, liability or claim relating
to hazardous substances or wastes, petroleum products or material environmental
laws applicable to Company operations in connection with any of its present or
former properties other than as described under "Business--Environmental
Matters." However, no assurance can be given that there are, or as a result of
possible future acquisitions there will be, no environmental conditions for
which the Company might be liable in the future or that future regulatory
action, as well as compliance with future environmental laws, will not require
the Company to incur costs for or at its properties that could have a material
adverse effect on the Company's financial condition and results of operations.

   Reliance on Executive Officers. The Company's success is partially
dependent upon the performance and continued availability of its current
executive officers. The Company does not have employment contracts with any
of its current executive officers. There can be no assurance that the Company
will be able to retain such officers, the loss of whom could have a material
adverse effect upon the Company. See "Management."

   Recent Publicity. On September 3, 1996, The Boston Globe, a regional daily
newspaper, published a business news article regarding the Company. The article
contained numerous statements about the Company and quotations from the
Company's Chief Executive Officer. The article did not set forth material
information or cautionary statements relevant to an evaluation of the statements
and quotations regarding the Company in the article. Prospective investors in
the Notes should not rely on such article and should only rely upon the
information and cautionary statements contained in this Prospectus, including
"Risk Factors" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

                                  THE COMPANY

   Iron Mountain is the largest records management company in the United States,
as measured by revenues. The Company is a full-service provider of records
management and related services, enabling customers to outsource data and
records management functions. Pro forma for the Acquisitions, as of June 30,
1996, the Company managed approximately 29.6 million Cartons in 103 records
centers in 33 markets nationwide. The Company has a diversified base of over
19,000 customer accounts, which includes more than half of the Fortune 500 and
numerous legal, banking, healthcare, accounting, insurance, entertainment and
government organizations. The Company provides storage and related services for
all major media, including paper (which is the dominant form of records
retention and which has accounted for approximately 85% of the Company's
revenues since 1992), computer disks and tapes, microfilm and microfiche, master
audio and video tapes, film and optical disks, X-rays and blueprints. The
Company's principal services include filing, retrieval and destruction of
records, courier pick-up and delivery, database management and customized
reporting. The Company also sells storage materials and provides consulting and
other records-related services.

   Iron Mountain's operations date to 1951, when a corporate predecessor
commenced storage operations in a network of underground vaults in a former iron
ore mine, focusing on the maximum-security storage of corporate vital records in
the Northeast. That company was acquired by Schooner Capital Corporation
("Schooner") in 1975, after which its focus shifted to more general records
management. In 1988, a corporate affiliate of Schooner acquired the Bell &
Howell Records Management Company and its subsidiaries ("BHRM") for
approximately $75 million. At that time, BHRM conducted storage operations in
various states, with significant operations in California. The current Iron
Mountain was incorporated in 1990 as part of a recapitalization that
consolidated the former BHRM operations with the predecessor's Northeast
operations.

   The principal executive offices of the Company are located at 745 Atlantic
Avenue, Boston, Massachusetts 02111. Its telephone number is (617) 357-4455.

                                THE TRANSACTIONS

   
   In connection with the Offering, the Company intends to: (i) repay all
indebtedness outstanding under the Credit Agreement; (ii) repay its 13.42%
Senior Subordinated Notes due December 14, 2000 (the "Chrysler Notes"); (iii)
repay certain indebtedness incurred by the Company in connection with a 1990
acquisition and represented by two junior subordinated notes (collectively, the

(1) Balances are as of June 30, 1996.

(2) Acquisitions completed after June 30, 1996 were initially financed by
    borrowings under the Credit Agreement and a portion of the net proceeds of
    the Offering will be used to repay such indebtedness.

(3) Consists of estimated fees and expenses related to the Offering, the
    repayment of the Credit Agreement, the Chryster Notes and the FDS Notes and
    the closing of the New Credit Facility.
    

   Repayment of Credit Agreement Indebtedness. The Company is party to the
Amended and Restated Credit Agreement dated as of January 31, 1995, as amended
(as so amended, the "Credit Agreement") among the Company, the lenders party
thereto and The Chase Manhattan Bank (National Association), as agent for such
lenders. Borrowings by the Company under the Credit Agreement during the most
recent twelve months were used to finance acquisitions and for working capital.
The Credit Agreement has a final maturity date of July 31, 2002. The weighted
average interest rate on September 3, 1996 on the indebtedness outstanding under
the Credit Agreement was 8.5%.

   Repayment of Chrysler Notes. Pursuant to a Note Purchase Agreement dated as
of December 14, 1990, as amended, the Company issued the Chrysler Notes in an
aggregate principal amount of $15.0 million to Chrysler Capital Corporation. The
Company will repay the Chrysler Notes in full with a portion of the net proceeds
of the Offering; the amount shown under "Uses of Funds" above does not include
related fees and expenses.

   Repayment of FDS Notes. In connection with a 1990 acquisition, the Company
issued to First Document Storage Corporation of America $450,000 in principal
amount of the FDS Notes, which mature in March 2000 and bear interest at the
rate of 8% per annum. In 1991, Schooner acquired $382,500 in principal amount of
the FDS Notes as an investment. The Company intends to use a portion of the net
proceeds from the Offering to repay the FDS Notes in their entirety.

   
   Pending Acquisition. A portion of the net proceeds from the Offering,
together with borrowings under the New Credit Facility, will be used to fund
the Pending Acquisition described under "Recent and Pending Acquisitions"
below.
    

   
   New Credit Facility. The Company intends to replace the Credit Agreement with
the New Credit Facility. The New Credit Facility will provide the Company with
revolving credit availability of up to $100 million for the Pending Acquisition
and possible future acquisitions, working capital and other corporate purposes,
and will terminate on September 30, 2001. As was the case with the Credit
Agreement, the Company's obligations under the New Credit Facility will be
guaranteed by substantially all of the Company's subsidiaries; however, unlike
the Credit Agreement, the New Credit Facility will be secured only by the pledge
of the stock of such subsidiaries. See "Description of New Credit Facility" for
a description of the anticipated terms of the New Credit Facility. No assurance
can be given that the Company will enter into the New Credit Facility on these
or any other terms. The Offering is not conditioned on the closing of the New
Credit Facility.

                        RECENT AND PENDING ACQUISITIONS

   
   As part of its growth strategy, since mid-1994 the Company has acquired or
entered into agreements to acquire 19 records management businesses. Since
January 1, 1995, the Company has purchased for cash 15 such businesses (the
"Completed Acquisitions") and has entered into a definitive agreement to acquire
one additional records management business (the "Pending Acquisition" and,
together with the Completed Acquisitions, the "Acquisitions"). 
    

   
   The total purchase price of the Completed Acquisitions was approximately
$80.1 million (not including contingent payments of up to $0.6 million based
upon the achievement of certain revenue targets during 1996 and 1997), and the
purchase price of the Pending Acquisition is approximately $20.2 million (not
including contingent payments of up to $4.0 million based upon the achievement
of certain revenue targets during 1997 and 1998). The Completed Acquisitions
represent in the aggregate total annual revenues of approximately $32.0 million,
and the Pending Acquisition represents total annual revenues of approximately
$8.8 million (calculated in each case by reference to the revenues of each such
acquired business during the twelve months ended December 31, 1995, which
calculation includes an estimate of total revenues for the portion of 1995, if
any, during which any such acquired business was included in the Company's
results of operations). See "Pro Forma Condensed Consolidated Financial
Information." 
    

   
   The following table presents certain information for each acquisition
completed since 1994 and for the Pending Acquisition.

   The closing of the Pending Acquisition is subject to various conditions and
no assurance can be given that the Pending Acquisition will be completed. See
"Risk Factors--Risks Associated with Acquisition Strategy." The Offering is not

                                USE OF PROCEEDS

   
   The gross proceeds from the Offering will be used: (i) to repay indebtedness
under the Credit Agreement, the Chrysler Notes and the FDS Notes; (ii) to fund a
portion of the purchase price of the Pending Acquisition; and (iii) to pay
certain fees and expenses related to the Offering. See "The Transactions" and
"Recent and Pending Acquisitions." The net proceeds to the Company from the
Offering are estimated to be approximately $144.7 million, after deducting
underwriting discounts and commissions and estimated Offering expenses. In the
event the Pending Acquisition is not consummated, the available net proceeds
from the Offering will be used for possible future acquisitions and for general
corporate purposes. Prior to funding the Pending Acquisition or to such other
use, the net proceeds from the Offering will be invested in short-term,
dividend-paying or interest-bearing investment grade securities.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

   
   The following unaudited Pro Forma Condensed Consolidated Balance Sheet has
been prepared based upon the unaudited historical condensed consolidated balance
sheet of Iron Mountain as of June 30, 1996 and the balance sheets as of June 30,
1996 of the Completed Acquisitions consummated after June 30, 1996 and the
Pending Acquisition, and gives effect to: (i) such Completed Acquisitions and
the Pending Acquisition; (ii) the closing under the New Credit Facility; and
(iii) the application of the estimated net proceeds from the Offering (after
deducting underwriting discounts and commissions and estimated expenses of the
Offering), as if each had occurred as of June 30, 1996. The following unaudited
Pro Forma Condensed Consolidated Statements of Operations for the six months
ended June 30, 1996 and for the year ended December 31, 1995 give effect to each
of the above transactions and to (i) the Completed Acquisitions which occurred
before June 30, 1996 and (ii) the Initial Public Offering and the application of
the net proceeds therefrom, as if each had occurred as of January 1, 1995. Pro
forma adjustments are described in the accompanying notes. 
    

   The following unaudited Pro Forma Condensed Consolidated Statements of
Operations are not necessarily indicative of the actual results of operations
that would have been reported if the events described above had occurred as of
January 1, 1995, nor do they purport to indicate the results of the Company's
future operations. Furthermore, the pro forma results do not give effect to all
cost savings or incremental costs that may occur as a result of the integration
and consolidation of the Acquisitions. In the opinion of management, all
adjustments necessary to present fairly such pro forma financial statements have
been made.

   The pro forma condensed consolidated financial information should be read in
conjunction with "Capitalization" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and with the Financial Statements
and the Notes thereto included elsewhere in this Prospectus.

               NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS

Overview

   
   In March 1995, the Company acquired National Business Archives, Inc.
("NBA") for $15.7 million. In October 1995, the Company acquired DataFile
Services, Inc. In December 1995, the Company acquired Data Management
Business Records Storage, Inc. ("Data Management") for $14.5 million. In
December 1995, the Company also acquired Brooks Records Center, Inc. In
January 1996, the Company acquired Nashville Vault Company, Ltd. ("Nashville
Vault") for $3.5 million. In January 1996, the Company also acquired Florida
Data Bank, Inc. ("FDB"). In February 1996, the Company acquired DataVault
Corporation. In March 1996, the Company acquired Data Storage Systems, Inc.
In April 1996, the Company acquired Brambles CRC, Inc. ("CRC"). In May 1996,
the Company acquired the records management business of Output Technologies
Central Region, Inc. In July 1996, the Company acquired the records
management business of The Fortress Corporation. In August 1996, the Company
acquired Data Archive Services, Inc. and Data Archive Services of Miami, Inc.
(collectively, "DAS") and DKA Industries, Inc. In September 1996, the Company
acquired International Record Storage and Retrieval Service, Inc. and
Security Archives Corporation. The results of operations of the Acquisitions
which were consummated prior to June 30, 1996 are included in the results of
operations of the Company from their respective dates of acquisition. The
historical balance sheet of the Company at June 30, 1996 includes the
acquisitions consummated prior to June 30, 1996. The aggregate purchase price
of the foregoing acquisitions, excluding NBA, Data Management and Nashville
Vault, was $46.4 million (not including contingent payments of up to $0.6
million based upon the achievement of certain revenue targets during 1996 and
1997).
    

   
   During September 1996, the Company entered into a definitive agreement to
purchase Mohawk Business Record Storage, Inc. ("Mohawk") for $20.2 million (not
including contingent payments of up to $4.0 million based upon the achievement
of certain revenue targets during 1997 and 1998). The closing of the Pending
Acquisition is subject to various conditions, and no assurance can be given that
such acquisition will be completed. All of the Completed Acquisitions have been,
and the Pending Acquisition, if consummated, will be, accounted for as
purchases. 
    

   The accompanying unaudited pro forma condensed consolidated financial
statements reflect the following as though each had occurred on January 1, 1995:
(i) the Initial Public Offering and the application of the net proceeds
therefrom; (ii) the Offering and the application of the net proceeds therefrom;
(iii) the closing of the New Credit Facility; and (iv) the Acquisitions. The
Company will record, in the quarter in which the Offering is consummated, an
extraordinary loss on retirement of debt, net of related tax benefit. As of June
30, 1996, the amount of such loss would have been approximately $2.2 million.
While the extraordinary charge has been reflected in the accompanying pro forma
balance sheet, the pro forma statements of operations do not give effect to such
loss. Such loss consists of the write-off of deferred financing costs, original
issue discount, prepayment penalty and loss on termination of interest rate
protection agreements.

Balance Sheet

   The aggregate consideration paid or to be paid for the Acquisitions is
approximately $100.3 million in cash (not including up to $4.6 million of
contingent payments based upon the achievement of certain revenue targets from
1996 through 1998). The excess of the purchase price over the book value of the
net assets acquired for each of the Acquisitions has been allocated to tangible
and intangible assets, based on the Company's estimate of the fair value of the
net assets acquired. The allocations of the purchase price as illustrated below
may change upon final appraisal of the fair value of the net assets acquired.

   The Acquisitions completed prior to June 30, 1996 were financed with
long-term debt and proceeds from the Initial Public Offering. The Acquisitions
completed after June 30, 1996 and the Pending Acquisition are assumed to be
financed with long-term debt. The Company will fund the purchase price of the
Pending Acquisition with a portion of the net proceeds from the Offering and the
New Credit Facility. See "Recent and Pending Acquisitions," "The Transactions"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations." 
    

   The accompanying pro forma condensed consolidated balance sheet as of June
30, 1996 has been prepared as if the Transactions had all been completed as of

Statements of Operations

   All of the Acquisitions, except Data Management, FDB, CRC and DAS, have a
December 31 fiscal year end. Data Management's and CRC's fiscal year end is June
30, DAS's fiscal year end is May 31 and FDB's fiscal year end is August 31.
Accordingly, Data Management's, CRC's, DAS's and FDB's results of operations
were calendarized to the twelve months ended December 31, 1995 and the six
months ended June 30, 1996.

   The accompanying pro forma condensed consolidated statements of operations
for the year ended December 31, 1995 and for the six months ended June 30, 1996
have been prepared as if the Transactions and the Initial Public Offering had
occurred on January 1, 1995 and reflect the following adjustments:

   (C) A pro forma adjustment has been made to eliminate a $0.7 million
non-recurring gain on the sale of property and equipment by Data Management in
the year ended December 31, 1995.

   
   (D) Pro forma adjustments for the six months ended June 30, 1996 and for the
year ended December 31, 1995 have been made to reduce cost of sales by $0.3
million and $1.1 million, respectively, to eliminate specific expenses that
would not have been incurred had the Acquisitions occurred at the beginning of
1995. Such cost savings relate to (i) the termination of certain employees due
to the integration and consolidation of certain Acquisitions and (ii) a
reduction in warehouse rent expense related to facilities the Company will
vacate upon completion of certain Acquisitions. 
    

   (E) Pro forma adjustments for the six months ended June 30, 1996 and for the
year ended December 31, 1995 have been made to reduce selling, general and
administrative expenses by $1.2 million and $2.6 million, respectively, to
eliminate specific expenses that would not have been incurred had the
Acquisitions occurred as of January 1, 1995. Such cost savings relate to (i) the
termination of certain employees due to the integration and consolidation of
certain Acquisitions and (ii) the elimination of related party expenses and
management fees in excess of amounts that would have been incurred by the
Company for the services rendered. Additional cost savings

                                       28


that the Company expects to realize through integration of the Acquisitions into
the Company's operations have not been reflected herein.

   (F) A pro forma adjustment has been made to reflect additional depreciation
and amortization expense on the fair value of the assets acquired and goodwill.
Property and equipment are depreciated over three to 50 years, goodwill is
amortized over 25 years and covenants not-to-compete are amortized over two to
five years on a straight-line basis. Such depreciation and amortization may
change upon final appraisal of the fair market value of the net assets acquired.

   (G) The pro forma adjustments to interest expense consist of the following:



                                                                                    June 30,     December 31,

   A 1/4% increase (or decrease) in the assumed 10-1/2% interest rate with
respect to the Notes would increase (or decrease) annual interest expense with
respect to the Notes by $375,000. A 1/8% increase (decrease) in the interest
rate with respect to the New Credit Facility would increase (decrease) annual
interest expense with respect to the assumed borrowings under the New Credit
Facility by approximately $17,000.

   (H) A pro forma adjustment has been made to adjust the provision for income
taxes to a 40% rate on pro forma income before nondeductible goodwill
amortization and other nondeductible expenses.

   (I) Pro forma adjustments of $0.3 million and $2.1 million for the periods
ended June 30, 1996 and December 31, 1995, respectively, have been made to
eliminate the accretion of a redeemable put warrant.

   (J) A pro forma adjustment has been made to adjust the pro forma weighted
average common and common equivalent shares outstanding as if the Initial Public
Offering had occurred on January 1, 1995.

(Footnotes from the preceding page)

(1) Earnings before interest, taxes, depreciation, amortization and
    extraordinary charges ("EBITDA"). Based on its experience in the records
    management industry, the Company believes that EBITDA is an important tool
    for measuring the performance of records management companies (including
    potential acquisition targets) in several areas, such as liquidity,
    operating performance and leverage. In addition, lenders use EBITDA as a
    criterion in evaluating records management companies, and substantially all
    of the Company's financing agreements contain covenants in which EBITDA is
    used as a measure of financial performance. However, EBITDA should not be
    considered an alternative to operating or net income (as determined in
    accordance with 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. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Overview" and "--Liquidity and Capital
    Resources" for discussions of other measures of performance determined in
    accordance with GAAP and the Company's sources and applications of cash
    flow.

(2) Growth capital expenditures include investment in racking systems, new
    buildings and leasehold improvements, equipment for new facilities,
    management information systems and facilities restructuring. See
    "Management's Discussion and Analysis of Financial Condition and Results
    of Operations--Liquidity and Capital Resources--Capital Investments."

(3) Includes $2,901 related to the cost of constructing a records management
    facility which was sold in a sale and leaseback transaction in the fourth
    quarter of 1994.

(4) The term "Carton" is defined as a measurement of the volume equal to a
    single standard storage carton, approximately 1.2 cubic feet. The number of
    Cartons stored does not include storage volumes in the Company's vital
    records services and data protection services which are described under
    "Business."

(5) The pro forma ratio of earnings to fixed charges, giving effect to the
    Transactions as if each had occurred as of January 1, 1995, would have been
    0.9x for the year ended December 31, 1995 and 0.9x for the six months ended
    June 30, 1996. For the year ended December 31, 1995 and the six months ended
    June 30, 1996, the Company would have needed to generate additional income
    from continuing operations, before provision for income taxes, of $1,576 and
    $358 to cover its pro forma fixed charges of $26,162 and $13,272,
    respectively. The ratio of earnings to fixed charges was 0.9x for the fiscal
    year ended December 31, 1991. For such period, the Company would have needed
    to generate additional income from continuing operations, before provision
    for income taxes, of $1,292 to cover its fixed charges of $11,689.

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

   The following discussion should be read in conjunction with the Selected
Consolidated Financial and Operating Information and Iron Mountain's
Consolidated Financial Statements and the Notes thereto and the other financial
and operating information included elsewhere in this Prospectus. This Prospectus
contains, in addition to historical information, forward-looking statements that
include risks and uncertainties. The Company's actual results may differ
materially from the results discussed in the forward-looking statements. Factors
that might cause such a difference include those discussed below, as well as
those discussed elsewhere in this Prospectus. The Company undertakes no
obligation to release publicly the result of any revisions to these
forward-looking statements that may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

Overview

   The Company's primary financial objective is to increase its EBITDA, which is
a source of funds to service indebtedness and for investment in continued
internal growth and growth through acquisitions. The Company has benefited from
growth in EBITDA, which has increased from $17.9 million in 1992 to $26.1
million in 1995 (a CAGR of 13.5%), but other measures of the Company's financial
performance, such as net income and net income applicable to common
stockholders, have been negatively affected by this objective. In 1994 and 1995,
the Company experienced net losses applicable to common stockholders. Such net
losses are attributable in part to significant increases in non-cash charges
associated with the Company's pursuit of its growth strategy, namely, (i)
increases in depreciation and amortization expenses associated with expansion of
the Company's storage capacity and the acquisition of certain large volume
accounts and (ii) increases in goodwill amortization associated with
acquisitions accounted for under the purchase method. In addition, net income
available to common stockholders has been negatively affected by a non-cash
charge for accretion of a redeemable put warrant, which was redeemed upon
completion of the Company's Initial Public Offering. See Note 5 of Notes to the
Company's Audited Consolidated Financial Statements.

   Iron Mountain's revenues consist of storage revenues and service and storage
material sales revenues. Storage revenues are derived from charges for storing
records (either on a per unit or a per cubic foot of records basis), and have
accounted for approximately 60% of total revenues in each of the last three
years and for the six months ended June 30, 1996. Service and storage material
sales revenues are derived primarily from the Company's courier operations
(consisting primarily of the pickup and delivery of records upon customer
request), additions of new Cartons, temporary removal of records from storage,
refiling of removed records, destructions of records, permanent withdrawals from
storage and sales of specially designed storage containers and related supplies.
Customers are generally billed on a monthly basis on contractually agreed-upon
terms.

   While the Company's total revenues have increased from $70.7 million in 1992
to $104.4 million in 1995, average revenue on a per Carton basis has declined
over this period. The year-over-year declines in average revenue per Carton for
1993, 1994 and 1995 were approximately 8%, 7% and 2%, respectively. Such
declines were attributable to: (i) increases in sales to large volume accounts,
which typically generate lower revenue per Carton (in particular the Resolution
Trust Corporation (the "RTC") account, which incorporated substantial volume
discounts, although such discounts were offset by revenues from special service
projects during 1993 and 1994); (ii) a facilities management arrangement with a
large volume account under which, prior to July 1996, the Company managed the
customer's records management facility and, therefore, the charges to the
customer prior to July 1996 did not include a rent component; and (iii)
industry-wide pricing pressures. Despite this decline, the Company has been able
to maintain its EBITDA margins through increased overall operating efficiencies
and economies of scale as well as specific efficiencies realized in the
servicing of large volume accounts. For 1992, 1993, 1994, 1995 and the six
months ended June 30, 1996, EBITDA margins were 25.3%, 22.8%, 23.8%, 25.0% and
24.2%, respectively.

   Pursuant to its 1992 contract with the RTC, the Company participated in the
consolidation and centralization of a large number of records on behalf of the
RTC. This activity, which entailed extensive services and the Company's start-up
of operations in two new markets, resulted in a significant increase in service
and storage material sales revenues in 1993. After the labor-intensive process
of assembling and inventorying the records was substantially completed in 1994,
the revenue from RTC service and storage material sales began to decrease, which
decrease was partially offset by increases in storage revenues due to an
increase in Cartons stored. The contract

                                       32


has been renewed effective July 27, 1996 for a one-year term by the Federal
Deposit Insurance Corporation (the "FDIC"), as successor in interest to the RTC,
and may be renewed at the option of the FDIC for three further terms of one year
each. Although the substantial costs of removing its records from the Company's
facilities may act as a disincentive to the FDIC to select another vendor, there
can be no assurance that this contract will be further renewed or that the terms
of any such renewal will be as favorable to Iron Mountain as the terms of the
current contract.

   Cost of sales consists primarily of wages and benefits, facility occupancy
costs, vehicle and other equipment costs and supplies. Of these, the most
significant are wages and benefits and facility occupancy costs. Over the past
several years, Iron Mountain has been able to reduce per Carton storage costs
by: (i) designing racking systems and operating space to maximize facility
storage efficiency; (ii) negotiating favorable facility leases and having
facilities built to its custom specifications; and (iii) leasing larger
facilities, which, when filled, are less expensive per Carton to operate.

   Selling, general and administrative expenses consist primarily of management,
administrative, sales and marketing wages and benefits, and also include travel,
communications, professional fees, bad debts, training, office equipment and
supplies expenses.

   The Company's depreciation and amortization charges result primarily from the
capital-intensive nature of the records management industry and the acquisitions
the Company has completed. The principal components of depreciation relate to
racking systems and related equipment, new buildings and leasehold improvements,
equipment for new facilities and computer system software and hardware.
Amortization primarily relates to goodwill and noncompetition agreements arising
from acquisitions and customer acquisition costs. The Company has accounted for
all of its acquisitions under the purchase method. Since the purchase price for
records management companies is usually substantially in excess of the book
values 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 decrease reported net income. Accordingly, the faster
the Company expands by making such acquisitions, the more likely it will be to
incur amortization charges, reducing net income.

   In February 1996, the Company received net proceeds of $33.3 million from its
Initial Public Offering. The Company used $6.6 million of such net proceeds to
repurchase a warrant to acquire 444,385 shares of Common Stock (the "Warrant").
For financial reporting purposes, the Company was required to record a non-cash
charge (based on the estimated redemption value calculated using the effective
interest rate method), resulting in substantial charges to net income applicable
to common stockholders over the period the Warrant was outstanding. See Note 5
of Notes to the Company's Audited Consolidated Financial Statements. The
remaining net proceeds were used by the Company to fund acquisitions (including
Completed Acquisitions consummated after the closing of the Initial Public
Offering), to repay indebtedness used to fund acquisitions and for working
capital.

   In December 1995, the Company decided to consolidate its corporate accounting
activities by transferring to Boston, Massachusetts those accounting activities
previously performed in Los Angeles, California. As a result of such transfer,
the Company recorded charges of $0.5 million and $0.3 million in the fourth
quarter of 1995 and the first six months of 1996, respectively.

Forward-Looking Statements Regarding Revenues

   One of the Company's goals is to achieve revenue growth of five to 10 percent
per year from its existing business through the end of 1997. In addition, over
the same period, the Company's goal is to achieve revenue growth of between 10
to 15 percent per year as a result of acquisitions. There can be no assurance
that the Company will be able to meet these goals. See "Risk Factors."

Six Months Ended June 30, 1996 Compared to Six Months Ended June 30, 1995

   Storage revenues increased from $30.7 million for the first six months of
1995 to $39.4 million for the first six months of 1996, an increase of $8.7
million or 28.0%. Ten acquisitions completed by the Company in 1995 and the
first six months of 1996 accounted for $5.5 million or 63.7% of such increase.
The balance of the storage revenues growth resulted primarily from net increases
in Cartons stored by existing customers and from sales to new customers.

   Service and storage material sales revenues increased from $19.5 million for
the first six months of 1995 to $24.6 million for the first six months of 1996,
an increase of $5.1 million or 26.2%. Acquisitions accounted for $3.4 million or
66.2% of such increase. The balance of such increase resulted from increases in
service and storage material sales to existing customers and the addition of new
customer accounts.

   For the reasons discussed above, total revenues increased from $50.2 million
for the first six months of 1995 to $64.0 million for the first six months of
1996, an increase of $13.8 million or 27.3%. Of such increase, $8.9 million or
64.6% was attributable to acquisitions completed by the Company in 1995 and the
first six months of 1996.

   Cost of sales (excluding depreciation) increased from $25.1 million for the
first six months of 1995 to $32.4 million for the first six months of 1996, an
increase of $7.3 million or 29.0%, and increased as a percentage of revenues
from 50.0% for the first six months of 1995 to 50.6% for the first six months of
1996. The increase was primarily attributable to the increase in Cartons stored,
increased expenses related to the severe winter weather on the Atlantic coast
during the first quarter of 1996 and expenses related to certain facility
relocations.

   Selling, general and administrative expenses increased from $12.7 million for
the first six months of 1995 to $16.1 million for the first six months of 1996,
an increase of $3.4 million or 26.5%, and decreased as a percentage of revenues
from 25.3% for the first six months of 1995 to 25.1% for the first six months of
1996. The $3.4 million increase was primarily attributable to the costs
associated with becoming a public company, with accelerated acquisition
activity, including certain redundant transitional expenses as new acquisitions
were integrated into the Company, and the addition of personnel needed to
support the Company's growth. Additionally, the selling, general

                                       34


and administrative expenses of acquired companies tend to be higher than Iron
Mountain's, and cost reductions and other possible synergies are not realized
immediately.

   Depreciation and amortization expense increased from $5.4 million for the
first six months of 1995 to $7.5 million for the first six months of 1996, an
increase of $2.1 million or 38.7%, and increased as a percentage of revenues
from 10.8% for the first six months of 1995 to 11.8% for the first six months of
1996. The increase was primarily attributable to the additional depreciation and
amortization expense related to the aforementioned acquisitions, capital
expenditures, including racking systems, information systems and improvements to
existing facilities, and additions to customer acquisition costs.

   As a result of the foregoing factors, operating income increased from $7.0
million for the first six months of 1995 to $8.0 million for the first six
months of 1996, an increase of $1.0 million or 14.1%. As a percentage of
revenues, operating income decreased from 13.9% for the first six months of 1995
to 12.5% for the first six months of 1996.

   Interest expense increased from $5.9 million for the first six months of 1995
to $6.4 million for the first six months of 1996, an increase of $0.5 million or
7.6%. The increase was primarily attributable to increased indebtedness to
finance acquisitions and capital expenditures. The decrease in interest expense
as a percentage of revenues was primarily attributable to a net decrease in
interest rates.

   As a result of the foregoing factors, income before provision for income
taxes increased from $1.1 million (2.1% of revenues) for the first six months of
1995 to $1.6 million (2.5% of revenues) in the first six months of 1996, an
increase of $0.5 million or 50.8%. Provision for income taxes increased from
$0.6 million (1.3% of revenues) for the first six months of 1995 to $0.9 million
(1.4% of revenues) for the first six months of 1996. The Company's effective tax
rate is higher than statutory rates primarily due to the amortization of the
nondeductible portion of goodwill associated with acquisitions made prior to the
change in tax laws which now generally permit deduction of such expenses.

   Net income increased from $0.4 million (0.8% of revenues) for the first six
months of 1995 to $0.7 million (1.1% of revenues) for the first six months of
1996, an increase of $0.3 million, or 66.0%. Net income (loss) applicable to
common stockholders was a $0.5 million net loss (1.1% of revenues), after
accretion of $0.9 million related to the Warrant, for the first six months of
1995 compared to net income of $0.4 million (0.7% of revenues), after accretion
of $0.3 million related to the Warrant, for the first six months of 1996. The
Warrant was redeemed in full in February 1996, with a portion of the proceeds
from the Initial Public Offering. As a result of such redemption, there will be
no future charges for such accretion.

   As a result of the foregoing factors, EBITDA increased from $12.4 million for
the first six months of 1995 to $15.5 million for the first six months of 1996,
an increase of $3.1 million, or 24.8%. As a percentage of revenues, EBITDA
decreased from 24.7% for the first six months of 1995 to 24.2% for the first six
months of 1996.

Year Ended December 31, 1995 Compared to Year Ended December 31, 1994

   Storage revenues increased from $54.1 million in 1994 to $64.2 million in
1995, an increase of $10.1 million or 18.6%. Seven acquisitions completed
between June 1994 and December 1995 accounted for $5.7 million or 56.7% of such
increase. The balance of the storage revenues growth resulted primarily from net
increases in Cartons stored by existing customers and from sales to new
customers.

   Service and storage material sales revenues increased from $33.5 million in
1994 to $40.3 million in 1995, an increase of $6.8 million or 20.1%. This
increase was accomplished despite a decrease of approximately $0.8 million in
such revenues received from the RTC, which decrease was primarily due to a
reduction in revenues from special service projects. Acquisitions accounted for
$4.3 million or approximately 63.5% of such increase. The balance of such
increase resulted from increases in service and storage material sales to
existing customers and the addition of new customer accounts.

   For the reasons discussed above, total revenues increased from $87.6 million
in 1994 to $104.4 million in 1995, an increase of $16.8 million or 19.2%. Of
such increase, $10.0 million or 59.4% was attributable to acquisitions made by
the Company between June 1994 and December 1995. The monthly average Cartons
stored increased approximately 22% in 1995 as compared to 1994, from
approximately 16.7 million Cartons to approximately 20.4 million Cartons. The
percentage increase was greater than that of total revenues primarily for the
reason described in the third paragraph under "Overview" above.

                                       35


   Cost of sales (excluding depreciation) increased from $45.9 million in 1994
to $52.3 million in 1995, an increase of $6.4 million or 13.9%, and decreased as
a percentage of revenues from 52.4% in 1994 to 50.1% in 1995. The $6.4 million
increase resulted primarily from an increase in Cartons stored. The decrease as
a percentage of revenues was due primarily to increased storage efficiencies
resulting from relocations to, or additions of, newer, higher density facilities
as well as increased utilization of storage capacity.

   Selling, general and administrative expenses increased from $20.9 million in
1994 to $26.0 million in 1995, an increase of $5.1 million or 24.9%, and
increased as a percentage of revenues from 23.8% in 1994 to 24.9% in 1995. The
$5.1 million increase was due primarily to increases in field management and
administrative staffing, including increases due to acquisitions. Of the 1.1%
increase as a percentage of revenues, $0.6 million (0.6% of revenues) resulted
from a provision for a judgment in a lawsuit relating to a 1992 incident and a
$0.5 million (0.5% of revenues) charge for the relocation of the corporate
accounting function from Los Angeles to Boston.

   Depreciation and amortization expenses increased from $8.7 million in 1994 to
$12.3 million in 1995, an increase of $3.6 million or 42.0%, and increased as a
percentage of revenues from 9.9% in 1994 to 11.8% in 1995. Depreciation and
amortization expenses, both in absolute dollars and as a percentage of revenues,
continued to increase, primarily as a result of the Company's acquisitions and
growth-related capital investments for racking systems, improvements to records
management facilities, information systems and customer acquisition costs.
Amortization during 1995 included a one-time charge of $0.9 million (0.9% of
revenues) in connection with the write-down of the goodwill of a subsidiary due
to the Company's decision to sell such subsidiary at an estimated price which is
$0.9 million less than such subsidiary's book value and related goodwill. The
Company subsequently decided not to sell such subsidiary.

   As a result of the foregoing factors, operating income increased from $12.2
million in 1994 to $13.8 million in 1995, an increase of $1.6 million or 13.0%,
and decreased as a percentage of revenues from 13.9% to 13.2%.

   Interest expense increased from $9.0 million in 1994 to $11.8 million in
1995. This increase was due primarily to increased levels of indebtedness
primarily to finance acquisitions, as well as higher interest rates and higher
deferred financing charges.

   As a result of the foregoing factors, income before provision for income
taxes decreased from $3.2 million (3.7% of revenues) in 1994 to $1.9 million
(1.9% of revenues) in 1995, a decrease of $1.3 million or 40.0%. Provision for
income taxes decreased from $2.0 million (2.2% of revenues) to $1.7 million
(1.7% of revenues). The Company's effective tax rates for 1994 and 1995 were
higher than statutory rates primarily due to $1.5 million and $2.5 million,
respectively, of amortization of nondeductible goodwill.

   Net income decreased $1.1 million from $1.3 million (1.5% of revenues) in
1994 to $0.2 million (0.2% of revenues) in 1995 as a result of the factors
outlined above.

   As a result of the foregoing factors, EBITDA increased from $20.9 million in
1994 to $26.1 million in 1995, an increase of $5.2 million or 25.1%, and
increased as a percentage of revenues from 23.8% to 25.0%. These increases
reflect continuing economies of scale and increased operating efficiencies,
which were partially offset by the $0.6 million (0.6% of revenues) reserve
relating to the judgment in the lawsuit referred to above and by the $0.5
million (0.5% of revenues) charge for the relocation of the corporate accounting
function from Los Angeles to Boston.

Year Ended December 31, 1994 Compared to Year Ended December 31, 1993

   Storage revenues increased from $48.9 million in 1993 to $54.1 million in
1994, an increase of $5.2 million or 10.6%. The substantial majority of the
storage revenues growth resulted from sales to new customers and increases in
Cartons stored from existing customers. Three acquisitions completed between
June and October 1994 accounted for only $0.8 million of the increase.

   Service and storage material sales revenues increased from $32.8 million in
1993 to $33.5 million in 1994, an increase of $0.7 million or 2.3%. This
increase was due primarily to an increase in services provided to existing and
new customers, which was partially offset by a $0.9 million decrease in such
revenues received from the RTC primarily due to a reduction in revenues from
special service projects.

   For the reasons discussed above, total revenues increased from $81.7 million
in 1993 to $87.6 million in 1994, an increase of $5.9 million or 7.3%. The
monthly average Cartons stored increased from approximately 14.5 million

                                       36


in 1993 to approximately 16.7 million in 1994, an increase of approximately 15%.
The percentage increase in Cartons stored was greater than that of total
revenues for the reasons discussed in the third paragraph under "Overview"
above.

   Cost of sales (excluding depreciation) increased from $43.1 million in 1993
to $45.9 million in 1994, an increase of $2.8 million or 6.6%, and decreased as
a percentage of revenues from 52.7% in 1993 to 52.4% in 1994. The $2.8 million
increase was due primarily to increases in storage capacity. The decrease as a
percentage of revenues was due primarily to increased storage efficiencies.

   Selling, general and administrative expenses increased from $20.0 million in
1993 to $20.9 million in 1994, an increase of $0.9 million or 4.4%, and
decreased as a percentage of revenues from 24.5% in 1993 to 23.8% in 1994. The
increase in such expenses was due primarily to inflationary increases in wages
and benefits, partially offset by a $0.2 million decrease in bad debt expense.
The decrease as a percentage of revenues was due to operating efficiencies and
the decrease of 0.3% in bad debt expense.

   Depreciation and amortization expenses increased from $6.8 million in 1993 to
$8.7 million in 1994, an increase of $1.9 million or 28.0%, and increased as a
percentage of revenues from 8.3% in 1993 to 9.9% in 1994. This increase, both in
dollars and as a percentage of revenues, was due primarily to an increase in
depreciation charges resulting from capital expenditures for racking systems and
improvements to records management facilities and information systems.

   As a result of the foregoing factors, operating income increased from $11.9
million in 1993 to $12.2 million in 1994, an increase of $0.3 million or 2.8%,
and decreased from 14.5% of revenues to 13.9% of revenues.

   Interest expense increased from $8.2 million in 1993 to $9.0 million in 1994,
an increase of $0.8 million or 9.2%, due primarily to increased levels of
indebtedness.

   As a result of the foregoing factors, income before provision for income
taxes decreased from $3.7 million in 1993 (4.5% of revenues) to $3.2 million in
1994 (3.7% of revenues), a decrease of $0.5 million or 11.4%. Provision for
income taxes decreased from $2.1 million in 1993 (2.6% of revenues) to $2.0
million in 1994 (2.2% of revenues). The Company's effective tax rates for
financial reporting purposes for 1994 and 1993 exceeded statutory tax rates
primarily because of $1.5 million of amortization of nondeductible goodwill in
each year.

   Net income decreased from $1.6 million (1.9% of revenues) to $1.3 million
(1.5% of revenues) as a result of the factors outlined above.

   As a result of the foregoing factors, EBITDA increased from $18.6 million in
1993 to $20.9 million in 1994, an increase of $2.3 million or 12.0%, and
increased as a percentage of revenues from 22.8% to 23.8%. The increase as a
percentage of revenues reflected economies of scale and increased operating
efficiencies.

Liquidity and Capital Resources

   In February 1996, the Company raised $33.3 million, net of underwriters'
discounts and commissions and associated costs, in the Initial Public Offering.
The net proceeds from the Initial Public Offering were used to retire the
Warrant, to fund acquisitions, to repay debt that had been incurred to make
acquisitions and for working capital.

   As the Company has sought to increase its EBITDA, it has made significant
capital investments, consisting primarily of acquisitions; growth-related
capital expenditures, including racking systems, information systems and
improvements to existing facilities; and customer acquisition costs. Cash paid
for these investments during the first six months of 1996 amounted to $19.2
million, $11.2 million and $0.7 million, respectively. These investments have
been primarily funded through a portion of the net proceeds of the Initial
Public Offering, cash flows from operations and borrowings under the Credit
Agreement.

   Stockholders' equity has been negatively affected primarily by the accretion
of the Warrant, interest expense, depreciation and amortization expenses
associated with expansion of the Company's storage capacity and the acquisition
of certain large volume accounts, and amortization of goodwill. In part as a
result of the Initial Public Offering, the Company's ratio of total debt to
stockholders' equity decreased from 3.1-to-1 at December 31, 1992 to 2.2-to-1 at
June 30, 1996. On a pro forma basis (after giving effect to the Transactions),
the ratio of total debt to stockholders' equity at June 30, 1996 would have been
3.3-to-1.

   The Company currently intends to apply a portion of the net proceeds from 
the Offering to the prepayment of the Credit Agreement, the Chrysler Notes
and the FDS Notes. The Company will record, in the quarter in which


                                       38


the Offering is consummated, an extraordinary loss on retirement of debt, net of
related tax benefit. Assuming the Transactions were to be consummated on
September 30, 1996, the amount of such loss would be approximately $2.0 million.
Such loss will consist of the write-down of deferred financing costs, original
issue discount, prepayment penalty and loss on possible termination of certain
interest rate protection agreements.

Capital Investments

   For 1994, 1995 and the six months ended June 30, 1996, the Company's
growth-related capital expenditures were $15.8 million, $14.4 million and $10.7
million, respectively. Included in capital expenditures for 1994 is $2.9 million
for the construction of a records management facility which was sold in a sale
and leaseback transaction. Growth-related capital expenditures consist primarily
of investment in racking systems, new building and leasehold improvements,
equipment for new facilities, management information systems and facilities
restructuring. For 1994, 1995 and the six months ended June 30, 1996, the
Company's maintenance capital expenditures were $1.2 million, $0.9 million and
$0.5 million, respectively.

   In addition, the Company incurs costs (net of revenues received for the
initial transfer of records) related to the acquisition of large volume accounts
(typically over 10,000 Cartons). For 1994, 1995 and the six months ended June
30, 1996, the Company's additions to customer acquisition costs were $1.4
million, $1.4 million and $0.7 million, respectively.

   The Company currently expects that its capital expenditures (other than
capital expenditures related to future acquisitions, which cannot be presently
estimated) for the second half of 1996 will be between $9 million and $10
million, and for 1997 will be between $18 million and $21 million. The Company
expects to fund these expenditures and costs from cash flows from operations and
by borrowings under the New Credit Facility.

Recent and Pending Acquisitions

   
   The Company's liquidity and capital resources have been significantly
impacted by acquisitions and, given the Company's acquisition strategy, may be
significantly impacted for the foreseeable future. In order to capitalize on
industry consolidation, the Company in mid-1994 adopted a more active
acquisition strategy. Since mid-1994, the Company has acquired or entered into
agreements to acquire 19 records management businesses, 18 of which have been
completed and one of which is pending, for a total purchase price of $103.2
million (not including contingent payments of up to $4.6 million based upon the
achievement of certain revenue targets during 1996 through 1998). The Company
has historically financed its acquisitions with borrowings under the Credit
Agreement in conjunction with cash flows provided by operations and, more
recently, from a portion of the proceeds of the Initial Public Offering. Net
borrowings for acquisitions during 1994, 1995 and the first six months of 1996
totaled $2.1 million, $32.3 million and $19.0 million, respectively. In
addition, subsequent to June 30, 1996, the Company has incurred an additional
$28.3 million under the Credit Agreement to fund the Completed Acquisitions
consummated after such date. The Company intends to use a portion of the net
proceeds from the Offering, together with borrowings under the New Credit
Facility, to fund the Pending Acquisition. The Company's future interest expense
may increase significantly as a result of the additional indebtedness the
Company may incur to finance possible future acquisitions. To the extent that
future acquisitions are financed by additional borrowings under the New Credit
Facility or other credit facilities, the resulting increase in debt and interest
expense could have a negative effect on such measures of liquidity as debt to
equity, EBITDA to debt and EBITDA to interest expense. 
    

Sources of Funds

   During the six months ended June 30, 1996, the Company generated $8.1 million
in cash flows from operations as compared to $8.2 million for the same period of
the prior year. Such change in cash flows from operations resulted from a $3.1
million increase in EBITDA and an increase in accounts payable, which were
partially offset by an increase in accounts receivable and other changes in
working capital accounts. During the years ended December 31, 1994 and 1995, the
Company generated cash flows from operations of $11.6 million and $15.7 million,
respectively.

   At December 31, 1995, the Company had estimated net operating loss
carryforwards of approximately $7.3 million for federal income tax purposes. As
a result of such loss carryforwards, cash paid for income taxes has historically
been substantially lower than the provision for income taxes.

                                       39


   Net cash flows provided by financing activities were $6.7 million and $34.1
million in 1994 and 1995, respectively, substantially all of which was provided
under the Credit Agreement, and $23.7 million for the six months ended June 30,
1996, substantially all of which was provided by the net proceeds of the Initial
Public Offering and under the Credit Agreement.

Credit Arrangements of the Company

   The Credit Agreement provides for total borrowings not to exceed $130 million
and consists of the following facilities: (i) a $15 million revolving working
capital facility; (ii) a $10 million term loan; (iii) a $55 million revolving
acquisition credit facility; and (iv) a $50 million term loan. At June 30, 1996,
all borrowings under the Credit Agreement bore interest at a weighted average
annual rate of 8.5%. The obligations under the Credit Agreement are secured by
substantially all of the Company's assets, including the stock of its operating
subsidiaries. The Company also has the Chrysler Notes outstanding. These
facilities require the Company to meet certain financial covenants and ratios.
See Note 3 of Notes to the Company's Audited Consolidated Financial Statements.

   
   The Company intends to apply a portion of the net proceeds from the Offering
to prepay in its entirety all indebtedness outstanding under the Credit
Agreement and the Chrysler Notes. See "The Transactions" and "Use of Proceeds."
In addition, the Company intends to terminate the Credit Agreement and to enter
into the New Credit Facility as a replacement bank credit facility. The New
Credit Facility will provide the Company with revolving credit availability of
$100 million for acquisitions, working capital and other corporate purposes. See
"Description of the New Credit Facility" for a more detailed description of the
anticipated terms of the New Credit Facility. No assurance can be given that the
Company will enter into the New Credit Facility on these or any other terms. The
Offering is not conditioned on the closing of the New Credit Facility.
    

   The annual maturities of Iron Mountain's indebtedness for the second half of
1996 and for 1997, 1998, 1999 and 2000 are $1.6 million, $3.4 million, $8.3
million, $8.4 million and $32.5 million, respectively. Giving pro forma effect
to the Transactions, the annual maturities of Iron Mountain's indebtedness for
the second half of 1996 and for 1997, 1998, 1999 and 2000 would be $0.1 million,
$0.4 million, $0.4 million, $0.4 million and $7.8 million, respectively.

   
   As of June 30, 1996, the Company had available under the Credit Agreement
$6.2 million under the working capital facility and $24.7 million under the
acquisition credit facility. Subsequent to June 30, 1996, the Company borrowed
$28.3 million under the acquisition credit facility to finance acquisitions, and
amended the Credit Agreement to increase the acquisition credit facility by $5.0
million. As of June 30, 1996, on a pro forma basis, after giving effect to the
Transactions (see "The Transactions" and "Use of Proceeds"), the Company would
have had $174.5 million in total indebtedness and an aggregate of approximately
$86.3 million available under the New Credit Facility. 
    

   Under the Credit Agreement, Iron Mountain is required to use, and may in the
future use, interest rate protection products to reduce its exposure to
increases in interest rates. Under the New Credit Facility, Iron Mountain will
also be required to use such interest rate protection products. As of June 30,
1996, the Company had $118.9 million of total debt, of which $26.0 million had
fixed interest rates and $92.9 million had variable interest rates, $30.0
million of which was covered by interest rate protection products, certain of
which may be terminated in connection with the repayment of the Credit
Agreement. See Note 3 of Notes to the Company's Audited Consolidated Financial
Statements.

Future Capital Needs

   Iron Mountain's ability to generate cash adequate to fund its needs depends
generally on the results of its operations and the availability of financing.
Management believes that cash flow from operations in conjunction with
borrowings from existing and possible future credit facilities will be
sufficient for the foreseeable future to meet debt service requirements and to
make possible future acquisitions and capital expenditures. Depending on the
pace of the Company's acquisitions, the Company may elect to seek additional
financing during the next two years. The Company anticipates that any such
financing will be debt financing, including the issuance of debt securities.
However, depending on market conditions and the preferences of acquisition
candidates, the Company would consider issuing equity securities. However, there
can be no assurance in this regard or that the terms available for any future
financing, if required, would be favorable to Iron Mountain.

Seasonality

   Historically, the Company's business has not been subject to seasonality in
any material respect.

Inflation

   Certain of the Company's expenses, such as wages and benefits, occupancy
costs and equipment repair and replacement, are subject to normal inflationary
pressures. Although the Company to date has been able to offset inflationary
cost increases through increased operating efficiencies, there can be no
assurance that the Company will be able to offset any future inflationary cost
increases through similar efficiencies or increased storage or service charges.

                                    BUSINESS

Introduction

   Iron Mountain is the largest records management company in the United States,
as measured by revenues. The Company is a full-service provider of records
management and related services, enabling customers to outsource data and
records management functions. Pro forma for the Transactions, as of June 30,
1996, the Company managed approximately 29.6 million Cartons in 103 records
centers in 33 markets nationwide. The Company has a diversified base of over
19,000 customer accounts, which includes more than half of the Fortune 500 and
numerous legal, banking, healthcare, accounting, insurance, entertainment and
government organizations. The Company provides storage and related services for
all major media, including paper (which is the dominant form of records
retention and which has accounted for approximately 85% of the Company's
revenues since 1992), computer disks and tapes, microfilm and microfiche, master
audio and video tapes, film and optical disks, X-rays and blueprints. The
Company's principal services include filing, retrieval and destruction of
records, courier pick-up and delivery, database management and customized
reporting. The Company also sells storage materials and provides consulting and
other records-related services.

The Records Management Industry

Overview

   Based on publicly available information, organizations in the United States
generate an estimated four trillion documents each year. Many of these documents
must be retained and available for reference for many years. These records may
be generally divided into two categories: active and inactive. Active records
relate to ongoing and recently completed activities or contain information that
is frequently referenced. Active records are usually stored and managed on-site
by the organization which originated them to ensure ready availability.

   Inactive records are the principal focus of the records management industry.
Inactive records consist of those records which are not needed for immediate
access but which must be retained for legal reasons or regulatory compliance or
for occasional reference in support of ongoing business operations. Based on
industry studies, the Company believes that inactive records make up
approximately 80% of all records.

[TRIANGLE GRAPHIC]

ACTIVE   20%
INACTIVE 80%

Growth of Market; Outsourcing

   The Company believes that the volume of inactive records is increasing for a
number of reasons, including: (i) the rapid growth of inexpensive
document-producing technologies such as facsimile, desktop printing and computer
networking; (ii) increased regulatory requirements; (iii) concerns over possible
future litigation and the resulting increases in volume and holding periods of
documentation; (iv) the high cost of reviewing records and deciding whether to
retain or destroy them; and (v) the failure of many entities to adopt or follow
policies on records destruction. Despite the growth of new "paperless"
technologies, such as the Internet and e-mail, management believes that stored
information remains predominantly paper-based and that such technologies have
promoted the creation of hard copies of such electronic information.

   The Company believes that the records management industry will gain a growing
share of this increased volume as more large organizations make the strategic
decision to outsource their records management as part of

                                       42


a growing trend to outsource a wide variety of functions that can be performed
more cost-effectively by third parties, though there can be no assurance in this
regard. Records management companies can offer occupancy and labor cost
reductions while at the same time providing greater levels of service than are
typically available in-house.

Highly Fragmented Industry

   Most records management companies serve a single local market, and are often
either owner-operated or ancillary to another business, such as a moving
company. According to the ACRC, as of January 1994 (the latest date for which
such information is available), approximately 2,600 firms offered records
storage and management services in the United States. The Company believes that
there are only four national providers in the industry (including the Company)
and that the rest are regional or, in most instances, single-city operators.

Increasing Industry Consolidation

   The Company believes that there is a trend towards consolidation in the
records management industry and that it will continue and accelerate because of
the industry's capital requirements for growth, customer demands for more
sophisticated technology solutions, a trend for certain large customers to
contract with one vendor in multiple cities and opportunities to achieve
economies of scale.

   The records management business requires significant up-front capital
investment for real estate, racking systems and management information
technology. Economies of scale available in these areas can reward larger
initial capital investments by reducing per unit storage costs. However, such
economies of scale are only realized once a facility begins storage operations
and fills available capacity. Thus, larger companies with both access to capital
and the ability to quickly fill a new facility enjoy a competitive cost
advantage, thereby putting pressures on smaller competitors.

Financial Characteristics of Iron Mountain's Business

   Iron Mountain's records management business has the following financial
characteristics:

   (bullet)Recurring Revenues. Iron Mountain derives a majority of its revenues
           from fixed periodic (usually monthly) fees charged to customers for
           storage of records. Storage revenues have grown for 30 consecutive
           quarters and have represented approximately 60% of the Company's
           total revenues in each of the last five years. Once a customer places
           a record in storage with the Company and until that record is
           destroyed or permanently removed (for which the Company typically
           receives a service fee), the Company receives recurring payments of
           fixed periodic fees without incurring additional labor or marketing
           expenses or significant capital costs. The stable and growing storage
           base also provides the foundation for increases in revenues and
           EBITDA from service activities and sales of storage materials.

   (bullet)Historically Non-Cyclical Business. Iron Mountain has not experienced
           a reduction of its business as a result of past general economic
           downturns, although there can be no assurances that this would be the
           case in the future. Management believes that the outsourcing of
           records management may accelerate during economic downturns as
           companies focus on reducing costs through outsourcing non-core
           operating functions. In addition, management believes that companies
           that have outsourced records management are less likely during
           economic downturns to incur the move-out costs and other expenses
           associated with switching vendors or moving records management
           in-house.

   (bullet)Inherent Growth from Existing Customers. The Company's customers have
           on average generated additional Cartons at a faster rate than stored
           Cartons have been destroyed or permanently removed. From 1992 to
           1995, net Cartons from existing customers grew at an average annual
           rate of 6.7%. The Company believes the consistent growth of its
           storage revenues is the result of a number of additional factors,
           including: (i) the trend toward increased records retention; (ii)
           customer satisfaction with the Company's services; and (iii) the
           costs and inconvenience of moving storage operations in-house or to
           another provider of records management services.

   (bullet)Diversified and Stable Customer Base. The Company has over 19,000
           customer accounts in a variety of industries. The Company
           currently provides services to more than half of the Fortune 500
           and numerous legal, banking, healthcare, accounting, insurance,
           entertainment and government organizations. Only one

                                       43


           of the Company's customers accounted for more than 3% of revenues in
           1993, 1994 or 1995. From 1992 to 1995, average annual permanent
           removals of Cartons represented only approximately 4% of total
           Cartons stored.

   (bullet)Capital Expenditures Related Primarily to Growth. The Company's
           business requires limited annual maintenance capital expenditures.
           Maintenance capital expenditures were $1.8 million, $1.2 million and
           $0.9 million in 1993, 1994 and 1995, respectively. From 1992 to 1995,
           over 90% of the Company's aggregate capital expenditures were
           growth-related investments, primarily in racking systems, new
           buildings and leasehold improvements, equipment for new facilities,
           management information systems and facilities restructuring. These
           growth-related capital expenditures are primarily discretionary and
           create additional capacity for increases in revenues and EBITDA.

Growth Strategy

   Iron Mountain's growth strategy is to expand aggressively in existing and new
markets through increased business from existing customers, additions of new
customers and acquisitions. The Company's goal is to be one of the largest
records management companies in each of its markets. In addition, through its
growth strategy, the Company seeks to attain increasing economies of scale in
order to provide high-quality service at competitive prices.

   The following table sets forth the Company's approximate growth in Cartons
stored by existing customers, new customers and as a result of acquisitions for
the three years ended December 31, 1993, 1994 and 1995 and the twelve months
ended June 30, 1996. The figures for the twelve months ended June 30, 1996 are
not necessarily indicative of the results that will be achieved for the twelve
months ended December 31, 1996.

- -----------
(1) Excludes storage volumes attributable to the Company's vital records
    services and data protection services.
(2) Gross Cartons added by the RTC or its successor the FDIC were
    approximately 0.9 million, 0.3 million, 0.3 million and 0.3 million for
    1993, 1994, 1995 and the twelve months ended June 30, 1996, respectively.
    RTC additions in 1993 are included in Additions from New Customers because
    the initial transfer of Cartons from the RTC commenced in the fourth quarter
    of 1992 and continued into 1993. Additions in 1994, 1995 and the twelve
    months ended June 30, 1996 are included in Additions from Existing
    Customers.

Growth from Existing Customers

   Existing Iron Mountain customers have contributed to storage and services
revenue growth because they have on average generated additional Cartons at a
faster rate than old Cartons are destroyed or permanently removed. In order to
maximize growth opportunities from existing customers, the Company seeks to
maintain high levels of customer retention by providing premium customer service
through its decentralized customer support staff.

                                       44


   The local customer support staff, working in conjunction with the corporate
staff, is also responsible for marketing additional services to existing
customers, including records tracking, indexing, customized reporting, vital
records management and records management consulting services.

Additions of New Customers

   The Company's direct sales force is dedicated solely to establishing new
account relationships and draws on the Company's national marketing organization
and senior management. New customer sales efforts have resulted in the addition
of more than 900 new customer accounts in each of the last three years.

   Iron Mountain segments its market into large volume accounts (typically over
10,000 Cartons) and standard accounts. As of June 30, 1996, large volume
accounts represented more than half of the total Cartons stored. The two
segments differ in complexity of service and technology needs, purchasing
behavior and purchasing leverage. The Company employs different database
marketing techniques, program design features and pricing structures to meet the
needs of each segment. In recent years the Company's large volume account
segment has grown rapidly, driven by strategic outsourcing initiatives and the
Company's marketing efforts. In 1993, 1994, 1995 and the six months ended June
30, 1996, large volume accounts represented 88%, 70%, 76% and 63% respectively,
of the additions of Cartons from new customers.

Growth through Acquisitions

   
   Iron Mountain has had a successful record of acquiring and integrating
smaller records management companies. From 1990 through 1994, Iron Mountain
completed five acquisitions. In order to capitalize on industry consolidation,
the Company in mid-1994 adopted a more active acquisition strategy and
implemented changes in its management, systems and financial infrastructure,
including the consummation of the Initial Public Offering, to execute such
strategy. Since June 1994, the Company has acquired or entered into agreements
to acquire 19 companies, 18 of which have been completed and one of which is
pending. The Company operates in 32 markets nationwide and intends to continue
to make fold-in acquisitions in existing markets and to make strategic
acquisitions in new geographic markets, with an emphasis on the 50 largest
markets in the United States. The Company's corporate development staff is
engaged in an ongoing review of acquisition candidates. As of the date hereof,
the Company is in contact with approximately 40 companies, and expects that it
will continue to meet several new candidates each month, although the actual
number may vary from month to month and there can be no assurance that any such
review will result in an acquisition. Management believes that Iron Mountain is
well positioned to participate in the further consolidation of the records
management industry. See "Risk Factors--Risks Associated with Acquisition
Strategy" and "Recent and Pending Acquisitions." 
    

   The Company seeks to expand its national presence, size and customer base
through new-market acquisitions. Management believes that the high start-up
costs of commencing operations make acquisitions an attractive means of entering
new markets. The Company seeks to acquire records management companies in
markets where management believes there is the potential for growth. Within such
markets, the Company uses a variety of criteria to evaluate acquisition
candidates, including the capacity and condition of existing storage facilities,
past and current operating performance and revenues and the experience and depth
of existing management. The Company is also considering investments in records
management businesses outside of the United States. See "Potential International
Investments."

   The Company believes that it can use its expertise and central administrative
organization to leverage the acquisition candidate's local market presence,
promoting the development of underperforming facilities and enhancing the value
of the local assets. The Company believes that its new-market acquisition
strategy could have a number of benefits, including: (i) continued growth in
revenues and EBITDA and diversification across a greater number of markets; (ii)
introduction of the Company's efficient storage, labor, transportation and other
operating efficiencies into new markets; (iii) the increased utilization of
efficiencies available through the Company's central administrative and
management information functions; (iv) increased market awareness of Iron
Mountain's national scope and presence; and (v) increased overall scale, which
should broaden the range of and facilitate the Company's capital-raising
activities. See "Risk Factors--Risks Associated with Acquisition Strategy."

   The Company also intends to continue to make fold-in acquisitions to augment
its operations in existing markets. The Company's goal in its existing markets
is to exploit economies of scale while maintaining high quality

                                       45


service. Following a new-market acquisition, the Company seeks to increase its
business with the acquired customer base and to supplement that growth with new
customers and, potentially, with appropriate fold-in acquisitions so that the
Company may benefit from economies of scale.

Premium Service Strategy

   Organizations selecting a provider of records management services consider a
number of factors in addition to price. Management believes that Iron Mountain
is a "premium" brand in the marketplace based upon its reputation for
reliability, customer-oriented organization, investment in technology and
national operating presence. The Company seeks to exploit its strengths in each
of these areas to maintain customer relationships and to attract new customers.

   Reputation for Reliability. The Company believes it has a reputation for
reliability based on its more than 40 years of operations, the continuity and
depth of its management, its successful historical growth, the quality and
diversity of its customer base which includes more than half the Fortune 500,
its technological capabilities and its size and financial resources.

   Customer-Oriented Organization and Locally Responsive Management. Iron
Mountain has developed a decentralized, local management structure that brings
significant management experience and stability to local markets and allows the
Company to respond directly, effectively and flexibly to customers. Broad
operating authority is delegated to regional Vice Presidents and to local
managers. In pursuing its acquisition strategy, Iron Mountain seeks to
capitalize upon the experience and strengths of existing management. In
addition, all full-time union and non-union employees participate in
incentive-based compensation programs that provide payments based on profits or
attainment of specified objectives for the unit in which they work. Iron
Mountain believes that the experience, stability and commitment of its regional
and local management is integral to its ability to provide superior customer
service and maximize growth potential.

   Investment in Technology. The Company has invested $12.5 million in
technology since 1992 in order to provide faster and more flexible solutions
for its customers and to enhance the quality and lower the costs of its own
operations. The Company believes that its technological capabilities,
especially its Safekeeper system, are a significant tool in attracting new
customers. The Company plans to continue to invest in its proprietary
technologies in the future. See "Technology and Development; Management
Information Systems."

   National Operating Presence. The Company believes it is one of only four
records management companies with a national operating presence. Traditionally,
the purchase decision for large multi-site customers has been made at the local
level. Recently, however, the Company has found that certain large organizations
have sought to obtain operating and economic efficiencies by outsourcing a
significant portion of their records management functions with a single records
management company. The Company seeks to use its national operating presence to
compete for such large multi-site customer accounts.

Low-Cost Operating Strategy

   Iron Mountain pursues a low-cost operating strategy based primarily on
achieving economies of scale in the areas of storage, labor and transportation,
general and administrative functions and management information systems. The
Company believes that it is one of the few records management companies with the
size and resources to realize significant economies of scale in these areas.

Storage Costs

   Because occupancy costs are a major component of the Company's cost of sales,
reducing per Carton storage costs is a primary strategic goal of the Company and
its real estate management staff. The Company seeks to minimize per Carton
storage costs by: (i) designing racking systems and operating space to maximize
facility storage efficiency; (ii) negotiating favorable facility leases and
having facilities built to its custom specifications; and (iii) leasing larger
facilities, which, when filled, are less expensive per Carton to operate. Since
1991, the Company has acquired or leased 11 custom-designed records management
facilities. The average Carton density (the ratio of standard Carton storage
capacity to total square feet of floor space) of these facilities is
approximately twice

                                       46


that of the Company's overall average Carton density. As a result of these
practices and after giving effect to the consummation of the Acquisitions,
average Carton density in the Company's facilities increased 32% from December
31, 1992 to June 30, 1996.

Labor and Transportation Efficiency

   The Company has made significant investments in computer technologies for its
service operations, resulting in greater efficiencies. In addition, by
increasing its operations and customer base in a local market area, the Company
seeks to maximize its courier delivery fleet usage and to increase delivery and
routing efficiencies.

   The Company's incentive structure has also contributed to labor efficiency.
Each of the Company's full-time employees participates in incentive compensation
programs based upon achievement of specific operating targets designed to
integrate the objectives and performance of records management facility
employees and managers. For the six months ended June 30, 1996, the Company's
employees earned incentive compensation in an amount equal to approximately
10.8% of the base wages paid by the Company.

   In part as a result of the foregoing factors, while the number of Cartons
stored at the Company's facilities between January 1, 1992 and June 30, 1996
increased by approximately 15.6 million (or approximately 144%), the Company's
staff increased during the same period by approximately 520 employees (or
approximately 65%).

G&A and MIS Efficiencies

   The Company's corporate staff provides support to local management in the
areas of acquisitions, marketing, facility acquisition and leasing, racking
system purchasing, finance and accounting and human resource management. In
addition, the Company's corporate staff is responsible for the design and
support of all records management technology. The Company believes that central
support in these areas provides local managers with competitive advantages over
smaller, local competitors and results in significant economies of scale.

Technology and Development; Management Information Systems

   The Company pioneered the application of advanced information technology to
the records management industry. Iron Mountain's proprietary Safekeeper system
provides advanced inventory control and information access, enabling the Company
to provide faster, higher quality and more flexible solutions to its customers
and to lower the costs of its operations. Iron Mountain's Safekeeper system
exploits bar-code technology to provide inventory integrity and a comprehensive,
standardized approach to tracking, accessing and retrieving records. Safekeeper
offers state-of-the-art records management capabilities and ease of access to
customers while featuring security functions to protect customer information
from unauthorized access. The system coordinates inventory control, order entry,
billing, material sales, service activity, accounts receivable and management
reporting, and features system-driven quality assurance and error-prevention.
Since 1992, the Company has invested $12.5 million to develop and refine its
management information systems, including Safekeeper.

   Safekeeper is built on an open systems architecture which is fully portable
and can be implemented in small processing environments with several users and
in large processing environments with hundreds of users. This allows the Company
a substantial measure of flexibility and vendor independence, and reduces the
risk of technological obsolescence.

   Safekeeper has improved the Company's customer support and operating
efficiency in the following ways:

   (bullet)Acquisition System Integration. Safekeeper has been designed to
           easily and effectively integrate newly acquired records management
           companies and offer improved levels of customer service and records
           management capabilities to customers acquired through acquisitions.
           The critical components of integrating acquisition systems are the
           abilities to match the acquired company's carton identifiers,
           location identifiers, records descriptive data, and billing data.
           Safekeeper is designed with flexible, comprehensive capabilities in
           each of these areas. Consequently, an acquired company's inventory
           can be converted to Safekeeper without having to relabel cartons or
           reset and relabel inventory locations. The customers of the acquired
           company retain their records data and receive similar billing rate
           structures. In addition, acquisition customers experience minimal
           disruption during integration and, after conversion, gain access to
           advanced records management and information access capabilities.
           Safekeeper utilizes a suite of

                                       47


           conversion routines to automate the conversion process and 
           effectively translate customer and inventory information.

   (bullet)Storage Efficiency. Safekeeper enables the Company to maximize the
           efficient use of storage space at its facilities. When cartons are
           added or returned to storage, Safekeeper identifies available space
           and the location of the customer's other records at the facility.
           Because there is a continual flow of cartons into and out of the
           Company's facilities, Safekeeper also permits facility operators to
           utilize space that becomes available as soon as cartons are removed.
           Safekeeper can pinpoint the location of any carton, enabling facility
           operators to quickly determine the optimal location for new or
           returning cartons.

   (bullet)Inventory Integrity. Bar-coding and scanning are used to track a
           carton or a record throughout its life cycle at Iron Mountain.
           Safekeeper identifies inventory discrepancies during the order
           processing cycle and forces their resolution before they affect the
           customer. This forced discrepancy resolution means that errors must
           be resolved before an order can be closed; until the order is closed,
           billing cannot be processed. Management believes that this
           system-driven quality assurance is a significant advantage over the
           "best efforts" approach used by most of its competitors.

   (bullet)Customer Information Access. Customers can access their records
           management data through a variety of formats, including direct access
           via Safekeeper Online, access on their own PCs via Safekeeper
           Desktop, integration of their internal system with Safekeeper via
           automated file transfers and paper reports. Safekeeper Online enables
           a customer to place orders directly via online access, resulting in
           efficiencies for Iron Mountain order processing. It features robust
           querying and searching tools to enable customers to identify records
           with only partial information. Safekeeper Desktop is a PC
           application, run from customers' desktop or network PCs; it provides
           customers with an entire set of records management data along with
           user-friendly tools for querying, reporting, and editing.
           Safekeeper's suite of file transfers enable customers to
           automatically transfer records data and service requests from their
           internal system to Safekeeper. The paper reports include inventory
           detail and summary, service activity analysis, quality assurance, and
           management review.

   (bullet)Records Management Flexibility. Safekeeper offers full life-cycle
           records management, from file creation to destruction, enabling each
           customer to establish schedules for records retention and destruction
           as dictated by the customer's specific needs. Safekeeper can flexibly
           accommodate large or small amounts of records management data in
           accordance with customer requirements. A series of customer-specific
           features and options allows Iron Mountain to tailor the records
           management functionality and reporting to the customer's needs.

   (bullet)Security. Safekeeper incorporates strict security protocols and
           procedures for all customers to prevent unauthorized access to a
           client's records information. Advanced security features that can
           automatically restrict access by departmental identification and/or
           type of service request are available to customers that are
           internally set up to provide this information.

   In addition to Safekeeper, the Company's data protection services facilities
utilize the Company's Media Link(tm) software, a state-of-the-art media
management system which provides integrated bar-code tracking and electronic
data interface between customer and Iron Mountain facilities, as well as audit
trail and remote inventory query functionality. The Company plans to continue to
invest in its proprietary technologies in the future in order to enhance its
customer service as well as to increase its own operating efficiency.

Description of Iron Mountain Records Management Services

   Iron Mountain's records management services consist primarily of the storage
operations for the management of hard copy documents. These and related services
and products sold have, since 1992, accounted for approximately 85% of the
Company's revenues. The balance of the Company's revenues come from the storage
and service of vital records and data protection, consulting and other services.

                                       48


Storage Operations

   Storage revenues accounted for approximately 60% of revenues in each of the
Company's last five fiscal years. Storage charges are generally billed monthly
on a per storage unit basis (usually either per unit or per cubic foot of
records) and include the provision of space, racking, computerized inventory and
activity tracking, physical security, environmental and climate control and fire
protection.

   The storage of a carton begins by issuing Safekeeper bar-coded labels to the
customer. The customer packs records in cartons and affixes the bar-coded label
to each carton. Customer personnel and the Iron Mountain driver conduct a
physical count of the cartons and the driver signs for the cartons, which are
then transported to the records management facility. Upon delivery to the
facility, the cartons are subjected to a second physical count. The cartons are
delivered to available space identified by Safekeeper and the bar-coded
information is scanned into the computer together with a bar-coded location
identifier. At the same time, a computer operator enters the customer's data
describing the stored material into the computer and the system confirms that
the cartons sent match the data entered in the computer. Under the Company's
computer control system, the order can only be closed out when all requisite
steps and checks have been completed and counts and locations have been
reconciled.

Service and Courier Operations

   Principal services include adding cartons to storage, temporary removal of
files or cartons from storage, refiling of removed records, permanent
withdrawals from storage and destruction of records. Service charges are
generally assessed for each procedure on a per unit basis. The Safekeeper system
controls the service processes from order entry through transportation and
invoicing.

   Courier operations consist primarily of the pickup and delivery of records
upon customer request. Courier delivery schedules can be tailored to fit
customers' needs, but generally customer orders received by 4:00 p.m. on a
business day are delivered the following business day. The Company also provides
same-day and immediate delivery during business hours and emergency delivery at
night and on weekends and holidays. Charges for courier services are based on
urgency of delivery, volume and location and are billed monthly as incurred. The
Company currently utilizes a fleet of approximately 250 owned or leased delivery
vehicles.

Vital Records Services

   Vital records contain critical or irreplaceable data such as master audio and
video recordings, film, software source code and other highly proprietary
information. Vital records may require special facilities or services, either
because of the data they contain or the media on which they are recorded. The
Company's charges for providing enhanced security and special climate-controlled
environments for vital records are higher than for typical storage functions.
The Company provides the same ancillary services for vital records as it
provides for its other storage operations.

Data Protection Services

   Data protection services consist of the storage, backup and archiving of
computer media as part of corporate disaster and business recovery plans.
Computer tapes, cartridges and disk packs are transported off-site by the
Company's courier operations on a scheduled basis to secure, climate-controlled
facilities, where they are available to customers 24 hours a day, 365 days a
year, to facilitate data recovery in the event of a disaster. This process is
managed by Iron Mountain's Media Link software, a state-of-the-art media
management system which provides integrated bar-code tracking, electronic data
interface between customer and Iron Mountain's facilities as well as audit trail
and remote inventory query functionality. Iron Mountain also manages tape
library relocation and supports disaster recovery testing and execution.

Additional Services and Products

   Iron Mountain offers a variety of additional services, which customers may
request or contract for on an individual basis. These services include
performing records inventories, packing records into cartons or other
containers, computerized indexing of files and individual documents, developing
schedules for the retention and destruction of records and records management
consulting services. The Company also sells a full line of specially designed
corrugated cardboard, metal and plastic storage containers.

                                       49


   The Company's subsidiary, Iron Mountain Information Partners, Inc., provides
professional consulting services to large customers, enabling them to develop
and implement comprehensive records management programs. The Company's
consulting business draws on the Company's 45 years of experience to analyze the
practices of such companies and assist them in creating more effective programs
of records management. The Company's consultants work with such customers to
develop policies for document review, analysis and evaluation and for scheduling
of document retention and destruction.

   In addition to its historical focus on the management of inactive records,
the Company has recently begun to provide services for the management of active
records. The Company can provide these services, which generally include
document and file processing and storage, both off-site at its own facilities
and by supplying its own personnel to perform management functions on-site at
the customer's premises. The Company sees active records management as a
potential source of future revenue growth for the Company, although there can be
no assurance in this regard.

Potential International Investments

   Iron Mountain is considering capitalizing upon its expertise in the records
management industry by making investments in records management businesses
outside the United States. From time to time, the Company has had discussions
concerning such investments. Such investments, if consummated, would be subject
to risks and uncertainties relating to the indigenous political, social,
regulatory, tax and economic structures of countries in those areas, as well as
fluctuations in currency valuation, exchange controls, expropriation and
governmental policies limiting returns to foreign investors. At this time, there
can be no assurance as to whether any such investment will be made or, if made,
will be successful in achieving its objectives.

Customers

   The Company's customer base is diversified in terms of revenue and industry
concentration. The Company has over 19,000 customer accounts. Iron Mountain
considers each invoice it delivers to its customers a separate customer account
and, accordingly, an organization which receives more than one invoice
represents multiple customer accounts. The chart below shows, as of June 1994,
the relative amounts of revenue attributable to certain business sectors.

[PIE CHART]

Other Financial Institutions   10%
Health Care                    10%
Professional Services           7%

Depository Institutions        14%
Insurance Companies             5%

   The Company services accounts of all sizes, from small businesses and
professional groups to over half of the Fortune 500. Other than the RTC or its
successor, the FDIC, which accounted for 7.4%, 6.3%, 4.8% and 3.6% of Iron
Mountain's revenues for the years ended December 31, 1993, 1994 and 1995 and the
six months ended June 30, 1996, respectively, no account or related set of
accounts generated more than 3% of Iron Mountain's revenues during any such
period.

   The Company's contract with the FDIC, as successor under the contract to the
RTC, was renewed effective July 27, 1996 for a one-year term, with three further
annual renewal options at the election of the FDIC. Although the substantial
costs of removing its records from the Company's facilities may act as a
disincentive to the FDIC

                                       50


to select another vendor, there can be no assurance that the contract will be
further renewed or that the terms of such renewal will be as favorable to
Iron Mountain as the terms of the current contract. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Overview."

Marketing and Sales

   The Company uses database marketing and a dedicated sales force to focus
exclusively on new business development. A corporate marketing organization
provides sales support, training, marketing communications and product
management as support functions. The program has successfully produced over 900
new customer accounts per year since 1991. The selling effort is bolstered by
regional and senior managers focused on key account selling.

Properties

   As of June 30, 1996, Iron Mountain conducted operations through 77 leased and
12 owned facilities containing a total of approximately 6.3 million square feet
of space. The leased facilities typically have initial lease terms of 10 years
with options to renew for an additional 10 years. The weighted average remaining
term of the leases on these facilities is approximately 7.0 years. In addition,
many of the leases contain either a purchase option or a right of first refusal
upon the sale of the property. The leases include one property leased from
affiliates of the Company. See "Management--Executive Compensation--Compensation
Committee Interlocks and Insider Participation" and Note 8 of Notes to the
Company's Audited Consolidated Financial Statements.

   As of June 30, 1996, the Company owned or leased (directly or through its
subsidiaries) the following records management facilities in the geographic

   The Company or its principal subsidiary is a guarantor of a substantial
portion of the leases to which other subsidiaries are party. Substantially all
of the property and assets currently owned and leased by the Company or its
subsidiaries are pledged as security for the lenders under the Credit Agreement.
It is expected that, in connection with the New Credit Facility, such liens
(other than the pledge of the stock of the Company's subsidiaries) will be
released. See Notes 3 and 7 of Notes to the Company's Audited Consolidated
Financial Statements for additional information regarding the Credit Agreement
and the minimum annual rental commitments of the Company, respectively.

                                       51


Employees

   A key feature of Iron Mountain's operating strategy is its decentralized
management structure and reliance on local management operating in local
business environments. The Company's operations are divided into three areas
comprising seven local management regions to maximize marketing and operating
effectiveness and to minimize supervisory costs. The management regions, each of
which is managed by a Vice President, are further divided into a total of 27
districts, each managed by a General Manager. The management regions are
overseen by offices in Boston and Los Angeles, but regional Vice Presidents and
General Managers have broad operating authority. The Company's headquarters
staff performs a variety of central administrative and support functions in
order to maximize the time and resources that local personnel can devote to
customer service and client development.

   Iron Mountain had approximately 1,200 full-time employees as of June 30,
1996, of whom approximately 89% are employed at the district level, 8% at the
corporate level and the balance at the area and regional levels.

   Approximately 11% of the Company's employees are represented by various
Teamsters Union locals under five different agreements. Two of these agreements,
representing 42 employees, have expired and are currently under negotiation.
Based on its prior experience with the two union locals involved in these
negotiations, the Company expects that it will enter into new agreements on
satisfactory terms. The remaining three contracts expire in December 1996, March
1997 and March 1999. In addition, at two of Iron Mountain's facilities an
election, subject to National Labor Relations Board regulations, was held on
June 20, 1996. A majority of the approximately 40 employees voted for
representation by a Teamsters Union local. The election results have not been
certified as of the date hereof.

   All non-union employees are eligible to participate in the Company's benefit
programs, which include medical, dental, life, short and long-term disability
and accidental death and dismemberment plans. Unionized employees receive these
types of benefits through their unions. In addition to base compensation and
other usual benefits, all full-time union and non-union employees participate in
some form of incentive-based compensation program that provides payments based
on profits, collections, or attainment of specified objectives for the unit in
which they work. Management believes that the Company has good relationships
with its employees and unions.

Competition

   Iron Mountain competes with three other national companies as well as a large
number of local and regional concerns. 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 Pierce
Leahy Corp., all of these competitors have records management revenues
significantly lower than those of the Company. To accommodate growth, a records
management vendor must invest in incremental storage capacity, which requires
added warehouses, racking systems, and related equipment including computer
systems capable of tracking increasingly large inventories. The amount of such
investment is significant relative to the immediate return that can be realized,
and the faster a vendor grows, the more capital is required. As a result, the
industry trend toward consolidation will, in management's opinion, continue and
accelerate. In addition, the Company 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. The Company also faces competition for
acquisition candidates.

   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 include
computer media, microforms, audio/video tape, film, CD-ROM and optical disk.
None of these technologies has replaced paper as the principal means for storing
information. 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 significantly reduce or supplant the use of paper as a preferred medium,
which could in turn adversely affect the Company's business.

                                       52


Insurance

   Iron Mountain carries a comprehensive property insurance policy with insurers
that it believes to be reputable and in amounts that it believes to be
appropriate, covering replacement cost of real and personal property, including
improvements. Subject to sub-limits, the policy also covers extraordinary
expenses associated with business interruption and damage or loss from flood or
earthquake, subject to certain deductibles. Separate policies for California
earthquake insurance carry other deductibles that may be significant. Iron
Mountain also maintains general liability and excess liability insurance
covering bodily injury, property damage and personal injury. See "Risk
Factors--Casualty."

   The Company's standard form of contract sets forth an agreed maximum value
for each carton or other storage unit held by the Company as a limitation on
liability for loss or damage, as permitted under the Uniform Commercial Code. In
contracts containing such limits, such values are nominal, and the Company
believes that in typical circumstances its liability would be so limited in the
event of loss or damage relating to the value of information stored on media
held by the Company. However, certain of the Company's agreements with certain
large volume accounts contain no such limits or contain higher limits or
supplemental insurance arrangements.

Environmental Matters

   Under various environmental laws, an owner of real estate or a lessee
conducting operations thereon may become liable for the costs of investigation,
removal or remediation of soil and groundwater contaminated by certain hazardous
substances or wastes or petroleum products. Certain such laws impose cleanup
responsibility and liability without regard to whether the owner or operator of
the real estate or operations 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 substances, or the failure to properly remediate such property
may adversely affect the current property owner's or operator's ability to sell
or rent such property or to borrow using such property as collateral. The owner
or operator of contaminated real estate also may be subject to common law claims
by third parties based on damages and costs resulting from off-site migration of
the contamination.

   Certain environmental laws govern the removal, encapsulation or disturbance
of ACMs. Such laws may impose liability for the release of ACMs and may enable
third parties to seek recovery from owners or operators of real estate for
personal injury associated with exposure to such substances. The Company is
aware of the presence of ACMs at some of the Company's facilities, but believes
that such materials are in acceptable condition at this time. The Company
believes that future costs related to any remediation of ACMs at these
facilities will not be material, either on an annual basis or in the aggregate,
although there can be no assurance with respect thereto.

   In addition, 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 substances or petroleum products
or the generation and disposal of hazardous wastes and, in some instances,
included the operation of USTs. In connection with its former and current
ownership or operation of certain properties, the Company may be potentially
liable for environmental costs such as those discussed above, and as more
specifically described below.

   At the Company's Hollywood, California facilities, certain USTs and
contaminated soils have been removed. Some additional contamination of soils and
groundwater remains and may be migrating. In 1990 and 1991, the Company filed
certain reports documenting its efforts and site conditions with the appropriate
environmental agencies pursuant to various environmental laws. Investigations
conducted on behalf of the Company in connection with its on-site remedial
activities disclosed that regional groundwater contamination, unrelated to the
Company's property, exists. At this time, the Company has not received any
notice from any regulatory agency or third party seeking further remediation of
soil or groundwater by the Company; however, there can be no assurance that such
further action will not be sought in the future. The Company has accrued
estimated costs of $0.8 million that it believes it may reasonably be expected
to incur in connection with this site if such additional remediation were to
become necessary; however, there can be no assurance as to the adequacy of such
accrual. The Company believes the ultimate outcome of the foregoing will not
have a material adverse effect on the Company's financial condition or results
of operations. See Note 7 of Notes to the Company's Audited Consolidated
Financial Statements.

   The Company has also from time to time conducted certain environmental
investigations and remedial activities at certain of its other former and
current facilities, but an in-depth environmental review of the properties has
not been conducted by or on behalf of the Company. The Company believes that it
is in substantial compliance

                                       53


with all applicable material environmental laws. 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
relating to hazardous substances or wastes, petroleum products or material
environmental laws applicable to Company operations in connection with any of
its present or former properties other than as described above. 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, as well
as compliance with future environmental laws, will not require the Company to
incur costs for or at its properties that could have a material adverse effect
on the Company's financial condition and results of operations.

Legal Proceedings

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

Compensation Committee Interlocks and Insider Participation

   Prior to November 1995, Iron Mountain's Compensation Committee of the
Board of Directors consisted of Constantin R. Boden and Vincent J. Ryan, who
was until November 17, 1995 the Chairman of the Board. The present
Compensation Committee consists of Mr. Little, who is the Chairman of the
Committee, and Messrs. Boden and Ryan.

   Messrs. Reese and Doggett are executive officers of Iron Mountain and are
directors of Schooner. Prior to November 1995, they were also executive
officers of Schooner. Mr. Ryan is the Chairman of the Board and principal
stockholder of Schooner.

   In 1993, the Company paid fees of $95,927 to Vincent J. Ryan for consulting
services. In each of 1994 and 1995, the Company paid fees of $111,048 to
Schooner for consulting services rendered by Mr. Ryan. These services and fees
terminated as of December 31, 1995.

   
   Iron Mountain Records Management, Inc. ("IMRM"), a subsidiary of the Company,
is the tenant under a lease dated January 1, 1991 for a 31,500 square-foot
building in Houston, Texas. The owner of the building is IM Houston (CR) Limited
Partnership, a Texas limited partnership, of which Mountain Realty, Inc., a
Massachusetts corporation whose sole stockholder is Vincent J. Ryan, is the sole
general partner, and the limited partners of which are C. Richard Reese and
Eugene B. Doggett. The term of the lease expires December 31, 2000, with two
five-year extension options exercisable by IMRM. IMRM currently pays annual rent
in the amount of approximately $94,000, subject to adjustment in 1997 and 1999
(and in the option periods if the term is extended) based upon percentage
changes in the consumer price index, with a floor of 3% and a ceiling of 5%,
compounded annually. As tenant, IMRM is responsible for taxes, insurance and
maintenance. The space is used by IMRM as a records management facility. During
1993, 1994, 1995 and the six months ended June 30, 1996, IMRM paid rent in the
annual amount of $88,000, $88,000, $93,000 and $47,000, respectively, under the
lease. The lease is, in the opinion of management, on commercially reasonable
terms, no less favorable to IMRM than could have been obtained from an
unaffiliated party at the time of the transaction.
    

   The Company paid compensation of $120,000, $144,000, $154,000 and $62,000
for 1993, 1994, 1995 and the six months ended June 30, 1996, respectively, to
Mr. T. Anthony Ryan. Mr. Ryan is Vice President, Real Estate, of the Company
and is the brother of Mr. Vincent J. Ryan, a Director and the former Chairman
of the Board of the Company. The Company believes that the terms of Mr.
Ryan's employment are no less favorable to it than would be negotiable with
an unrelated third party.

   Iron Mountain is indebted to Schooner in the principal amount of $382,500
under a junior subordinated note, which was incurred by Iron Mountain in 1990 in
connection with an acquisition. Schooner subsequently acquired the note from the
holder as an investment. The Company intends to use a portion of the net
proceeds from the Offering to prepay such indebtedness in its entirety.
See "The Transactions--Repayment of FDS Notes."

   
   Schooner leases space from Iron Mountain at Iron Mountain's corporate
headquarters. Such lease is a tenancy- at-will and may be terminated by either
Iron Mountain or Schooner at any time. As consideration for such lease, Schooner
pays rent to Iron Mountain based on its pro rata share of all expenses related
to the use and occupancy of the premises. The rent paid by Schooner to Iron
Mountain under such lease was approximately $48,000, $58,000, $49,000 and
$33,000 in 1993, 1994, 1995 and the six months ended June 30, 1996,
respectively. 
    

   Employees of Schooner were eligible to participate in the Iron Mountain
Profit Sharing Retirement Plan, a Section 401(k) plan, as well as the Company's
group medical, dental, life, disability and accidental death and dismemberment
arrangements (the "Company Benefit Plans"). Schooner reimbursed the Company for
costs incurred as a result of the participation of Schooner employees in Company
Benefit Plans. Participation by Schooner employees in the Company Benefit Plans
terminated shortly after the consummation of the Initial Public Offering.

Director Compensation

   Directors who are employees of the Company do not receive additional
compensation for serving as directors. Each director who is not an employee of
the Company (each an "Eligible Director") receives an annual retainer fee of
$10,000 as compensation for his or her services as a member of the Board of
Directors and is also paid $2,500 per quarter (to a maximum of $10,000 per year)
for attendance at meetings (the "Director's Compensation"). All directors of the
Company are reimbursed for out-of-pocket expenses incurred in attending meetings
of the Board of Directors or committees thereof, and for other expenses incurred
in their capacities as directors of the Company.

                                       58


Pursuant to the Iron Mountain Incorporated 1995 Stock Plan for Non-Employee
Directors (the "Directors Plan"), Eligible Directors may elect to receive all or
a portion of their Director Compensation in the form of Common Stock. An
Eligible Director electing to receive Common Stock under the Directors Plan
will, as an incentive, receive in lieu of cash an amount of Common Stock
equivalent to 110% of the Director Compensation otherwise due to be paid in
cash. The Company has reserved 15,000 shares of Common Stock for issuance under
the Directors Plan.

Stock Option Information

   Effective November 30, 1995, Iron Mountain instituted the Iron Mountain
Incorporated 1995 Stock Incentive Plan (the "Stock Option Plan"), which is
administered by the Compensation Committee, as a restatement of Iron Mountain's
then-existing stock option plan. The purpose of the Stock Option Plan is to
encourage key employees, directors, and consultants of the Company and its
subsidiaries who render services of special importance to, and who have
contributed or may be expected to contribute materially to the success of, the
Company or a subsidiary to continue their association with the Company and its
subsidiaries by providing favorable opportunities for them to participate in the
ownership of the Company and in its future growth through the granting of
restricted shares ("Restricted Stock"), options to acquire Common Stock
("Options"), stock appreciation rights ("SARs") and other rights to compensation
in amounts determined by the value of the Common Stock. Restricted Stock, SARs
and other rights are referred to collectively as "Other Rights."

   The total number of shares of Common Stock that may be subject to Options and
Other Rights under the Stock Option Plan may not exceed 1,000,000. As of June
30, 1996, options for 757,827 shares of Common Stock were outstanding under the
Stock Option Plan and 213,258 shares of Common Stock were available for grants
of Options and/or Other Rights under the Stock Option Plan. The duration of the
Options granted under the Stock Option Plan may be specified pursuant to each
respective stock option agreement, but in no event can any Option intended to
qualify as an incentive stock option (an "ISO") within the meaning of Section
422 of the Internal Revenue Code of 1986, as amended (the "Code"), be
exercisable after the expiration of 10 years after the date of grant. In the
case of any employee who owns (or is considered under Section 424(d) of the Code
as owning) stock possessing more than 10% of the total combined voting power of
all classes of stock of the Company or any of its Subsidiaries, no ISO shall be
exercisable after the expiration of five years from its date of grant.

   The following table sets forth certain information concerning the grant of
Options to Messrs. Wendell and Swift. Neither of the other Named Executive
Officers was granted Options in 1995.

(1) Options granted to Mr. Wendell with respect to 29,410 shares of Common Stock
    expire February 5, 2006, and options with respect to the remaining 6,059
    shares expire 60 days after termination of Mr. Wendell's employment with the
    Company.
(2) Potential Realizable Value is based on the assumed growth rates for an
    assumed ten-year option term. 5% annual growth results in a Common Stock
    price per share of $26.27, and 10% results in a Common Stock price per share
    of $41.82, respectively, for such term. The actual value, if any, an
    executive may realize will depend on the excess of the market price of the
    Common Stock over the exercise price on the date the option is exercised, so
    that there is no assurance the value realized by an executive will be at or
    near the amounts reflected in this table.

                            DESCRIPTION OF THE NOTES

General

   
   The Notes will be issued pursuant to an Indenture (the "Indenture") among the
Company, the Subsidiary Gaurantors (as defined below) and First Bank National
Association, as trustee (the "Trustee"). The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (the "Trust Indenture Act"). The Notes are subject
to all such terms, and Holders of Notes are referred to the Indenture and the
Trust Indenture Act for a statement thereof. The following summary of certain
provisions of the Indenture does not purport to be complete and is qualified in
its entirety by reference to the Indenture, including the definitions therein of
certain terms used below. A copy of the proposed form of Indenture has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. The definitions of certain terms used in the following summary are set
forth below under "Certain Definitions."
    

Principal, Maturity and Interest

   The Notes will be general unsecured obligations of the Company, will be
limited in aggregate principal amount to $150 million and will mature on 
               , 2006. Interest on the Notes will accrue at the rate of   % per 
annum and will be payable semi-annually in arrears on and                     ,
commencing on                  , 1997, to Holders of record on the immediately 
preceding and                . Interest on the Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of original issuance. Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months. The Notes will be payable both
as to principal and interest at the office or agency of the Company maintained
for such purpose within the City and State of New York or, at the option of the
Company, payment of interest may be made by check mailed to the Holders of Notes
at their addresses set forth in the register of Holders of Notes. Until
otherwise designated by the Company, the Company's office or agency in New York
will be the office of the Trustee maintained for such purpose. The Notes will be
issued in registered form, without coupons, and in denominations of $1,000 and
integral multiples thereof.

Subsidiary Guarantees

   
   The Company's payment obligations under the Notes will be jointly and
severally guaranteed (the "Subsidiary Guarantees") on an unsecured senior
subordinated basis by all of the Company's existing and future Restricted
Subsidiaries other than the Excluded Restricted Subsidiaries (each, a
"Subsidiary Guarantor"). See "Certain Covenants--Additional Subsidiary
Guarantees." Each Subsidiary Guarantee will be subordinated to the prior payment
in full of all Senior Debt of each such Subsidiary Guarantor, which on a pro
forma basis would have been $24.5 million at June 30, 1996 for all Subsidiary
Guarantors. Notwithstanding the subordination provisions contained in the
Indenture, the obligations of a Subsidiary Guarantor under its Subsidiary
Guarantee will be unconditional. See "Risk Factors--Unenforceability and Release
of Guarantees." 
    

Subordination

   The payment of principal of, premium, if any, and interest on the Notes will
be subordinated in right of payment, as set forth in the Indenture, to the prior
payment in full in cash of all Obligations with respect to Senior Debt, whether
outstanding on the date of the Indenture or thereafter incurred.

   Upon any payment or distribution to creditors of the Company or any
Subsidiary Guarantor in a liquidation or dissolution of the Company or such
Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or any Subsidiary
Guarantor or its property, an assignment for the benefit of creditors or any
marshaling of the assets and liabilities of the Company or any Subsidiary
Guarantor, (a) the holders of Senior Debt will be entitled to receive payment in
full in cash of all Obligations due in respect of such Senior Debt (including
interest after the commencement of any such proceeding at the rate specified in
the applicable Senior Debt, whether or not allowed as a claim in such
proceeding) before the Holders of Notes will be entitled to receive any payment
or distribution with respect to the Notes, and (b) until all Obligations with
respect to Senior Debt are paid in full in cash, any payment or distribution to
which the Holders of Notes would be entitled shall be made to the holders of
Senior Debt.

                                       63


   Neither the Company nor any Subsidiary Guarantor may make any payment or
distribution upon or in respect of the Notes, including, without limitation, by
way of set-off or otherwise, or redeem (or make a deposit in redemption of),
defease or acquire any of the Notes for cash, properties or securities if (a) a
default in the payment of any Obligation in respect of any Senior Debt occurs
and is continuing or (b) any other default (or any event that, after notice or
passage of time would become a default) (a "Non-Monetary Default") occurs and is
continuing with respect to Senior Debt and, in the case of clause (b), the
Trustee receives a notice of such default (a "Payment Blockage Notice") from the
holders (or the agent or representative of such holders) of any Designated
Senior Debt. Payments on the Notes may and shall be resumed (i) in the case of a
payment default, on the date on which such default is cured or waived and (ii)
in the case of a Non-Monetary Default, on the earlier of the date on which such
Non-Monetary Default is cured or waived or 179 days after the date on which the
applicable Payment Blockage Notice is received, unless the maturity of any
Senior Debt has been accelerated. Any number of Payment Blockage Notices may be
given, provided, however, that (A) not more than one Payment Blockage Notice may
be commenced during any period of 360 consecutive days and (B) any Non-Monetary
Default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee (to the extent the holder of Designated Senior
Debt, or such trustee or agent, giving such Payment Blockage Notice had
knowledge of the same) shall not be the basis for a subsequent Payment Blockage
Notice, unless such default has been cured or waived for a period of not less
than 90 consecutive days.

   The Indenture will further require that the Company promptly notify holders
of Senior Debt if payment of the Notes is accelerated because of an Event of
Default.

   As a result of the subordination provisions described above, in the event of
a liquidation or insolvency, Holders of Notes may recover less ratably than
creditors of the Company who are holders of Senior Debt. On a pro forma basis,
after giving effect to the Transactions, the principal amount of Senior Debt of
the Company and the Restricted Subsidiaries outstanding at June 30, 1996 would
have been $24.5 million. The Indenture will not limit the amount of additional
Indebtedness, including Senior Debt, that the Company and its Subsidiaries can
incur if certain financial tests are met. See "Certain Covenants--Incurrence of
Indebtedness and Issuance of Preferred Stock."

Optional Redemption

   The Notes will not be redeemable at the Company's option prior to 
           , 2001. Thereafter, the Notes will be subject to redemption at the 
option of the Company, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest thereon to but
excluding the applicable redemption date, if redeemed during the twelve-month
period beginning on of the years indicated below:

Year                       Percentage
- ----                       ----------
2001                             %
2002                             %
2003                             %
2004 and thereafter           100%

   Notwithstanding the foregoing, at any time during the first 36 months after
the date of issuance of the Notes, the Company may redeem up to 35% of the
initial principal amount of the Notes originally issued with the net proceeds of
one or more Qualified Equity Offerings at a redemption price equal to   % of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to but
excluding the date of redemption; provided, that at least 65% of the principal
amount of Notes originally issued remains outstanding immediately after the
occurrence of any such redemption and that such redemption occurs within 60 days
following the closing of any such Qualified Equity Offering.

                                       64


Mandatory Redemption

   Except with respect to required repurchases upon the occurrence of a Change
of Control or in the event of certain Asset Sales, each as described below under
"Repurchase at the Option of Holders," the Company is not required to make
sinking fund or redemption payments with respect to the Notes.

Repurchase at the Option of Holders

   Change of Control

   Upon the occurrence of a Change of Control, each Holder of Notes will have
the right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") at an offer price in cash equal
to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest, if any, to but excluding the date of purchase (the "Change of Control
Payment"). Within 30 calendar days following any Change of Control, the Company
will mail a notice to each Holder stating: (a) that the Change of Control Offer
is being made pursuant to the covenant entitled "Change of Control" and that all
Notes tendered will be accepted for payment; (b) the purchase price and the
purchase date, which will be no earlier than 30 calendar days nor later than 60
calendar days from the date such notice is mailed (the "Change of Control
Payment Date"); (c) that any Note not tendered will continue to accrue interest;
(d) that, unless the Company defaults in the payment of the Change of Control
Payment, all Notes accepted for payment pursuant to the Change of Control Offer
will cease to accrue interest on and after the Change of Control Payment Date;
(e) that Holders electing to have any Notes purchased pursuant to a Change of
Control Offer will be required to surrender the Notes, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Notes completed, to
the Paying Agent at the address specified in such notice prior to the close of
business on the fifth Business Day preceding the Change of Control Payment Date;
(f) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day
preceding the Change of Control Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have such Notes purchased; and (g) 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, which
unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof. The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable to the repurchase of the
Notes in connection with a Change of Control.

   On the Change of Control Payment Date, the Company will, to the extent
lawful, (a) accept for payment Notes or portions thereof tendered pursuant to
the Change of Control Offer, (b) deposit with the Paying Agent an amount equal
to the Change of Control Payment in respect of all Notes or portions thereof so
tendered and (c) deliver or cause to be delivered to the Trustee the Notes so
accepted together with an Officers' Certificate stating the Notes or portions
thereof tendered to the Company. The Paying Agent will promptly mail to each
Holder of Notes so accepted the Change of Control Payment for such Notes, and
the Trustee will promptly authenticate and mail to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any;
provided that each such new Note will be in a principal amount of $1,000 or an
integral multiple thereof.

   Except as described above with respect to a Change of Control, the Indenture
does not contain provisions that permit the Holders of the Notes to require that
the Company repurchase or redeem the Notes in the event of a takeover,
recapitalization or similar restructuring, nor does it contain any other "event
risk" protections for Holders of the Notes.

   Although the Change of Control provision may not be waived by the Company,
and may be waived by the Trustee only in accordance with the provisions of the
Indenture, there can be no assurance that any particular transaction (including
a highly leveraged transaction) cannot be structured or effected in a manner not
constituting a Change of Control.

   
   The Credit Agreement currently prohibits the Company from purchasing any
Notes prior to the expiration of the Credit Agreement and also provides that
certain change of control events with respect to the Company would constitute a
default thereunder. The New Credit Facility will contain, and any future credit
agreements or other 
    

                                       65


agreements relating to Senior Debt to which the Company becomes a party may
contain, similar restrictions and provisions. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing Notes, the
Company could seek the consent of its lenders to the purchase of Notes or could
attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company
will remain prohibited from purchasing Notes. In such case, the Company's
failure to purchase tendered Notes would constitute an Event of Default under
the Indenture which would, in turn, constitute a default under the Credit
Agreement and is expected to constitute an event of default under the New Credit
Facility. In such circumstances, the subordination provisions in the Indenture
would likely restrict payments to the Holders of Notes.

   "Change of Control" means the occurrence of any of the following events:

     (a) any "person" or "group" (as such terms are used in Sections 13(d) and
   14(d) of the Exchange Act), other than the Principal Stockholders (or any of
   them), is or becomes the "beneficial owner" (as defined in Rules 13d-3 and
   13d-5 under the Exchange Act), directly or indirectly, of more than a
   majority of the voting power of all classes of Voting Stock of the Company;

     (b) the Company consolidates with, or merges with or into, another Person
   or conveys, transfers, leases or otherwise disposes of all or substantially
   all of its assets to any Person, or any Person consolidates with, or merges
   with or into, the Company, in any such event pursuant to a transaction in
   which the outstanding Voting Stock of the Company is converted into or
   exchanged for cash, securities or other property, other than any such
   transaction where (i) the outstanding Voting Stock of the Company is not
   converted or exchanged at all (except to the extent necessary to reflect a
   change in the jurisdiction of incorporation) or is converted into or
   exchanged for (A) Voting Stock (other than Disqualified Stock) of the
   surviving or transferee Person or (B) cash, securities and other property
   (other than Capital Stock described in the foregoing clause (A)) of the
   surviving or transferee Person in an amount that could be paid as a
   Restricted Payment as described under the "Restricted Payments" covenant and
   (ii) immediately after such transaction, no "person" or "group" (as such
   terms are used in Sections 13(d) and 14(d) of the Exchange Act), other than
   the Principal Stockholders (or any of them), is the "beneficial owner" (as
   defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or
   indirectly, of more than a majority of the total outstanding Voting Stock of
   the surviving or transferee Person;

     (c) during any consecutive two-year period, individuals who at the
   beginning of such period constituted the Board of Directors (together with
   any new directors whose election to such Board of Directors, or whose
   nomination for election by the stockholders of the Company, was approved by a
   vote of 66-2/3% of the directors then still in office who were either
   directors at the beginning of such period or whose election or nomination for
   election was previously so approved) cease for any reason to constitute a
   majority of the Board of Directors then in office; or

     (d) the Company is liquidated or dissolved or adopts a plan of liquidation
   or dissolution other than in a transaction which complies with the provisions
   described under "Consolidation, Merger and Sale of Assets." 

   Asset Sales

   The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, (a) sell, lease, convey or otherwise dispose
of any assets (including by way of a Sale and Leaseback Transaction, but
excluding a Qualifying Sale and Leaseback Transaction) other than sales of
inventory in the ordinary course of business (provided that the sale, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company will be governed by the provisions of the Indenture described above
under the caption "Change of Control" and/or the provisions described below
under the caption "Merger, Consolidation or Sale of Assets" and not by the
provisions of this covenant), or (b) issue or sell Equity Interests of any of
its Restricted Subsidiaries, that, in the case of either clause (a) or (b)
above, whether in a single transaction or a series of related transactions, (i)
have a fair market value in excess of $1.0 million, or (ii) result in Net
Proceeds in excess of $1.0 million (each of the foregoing, an "Asset Sale"),
unless (x) the Company (or the Restricted Subsidiary, as the case may be)
receives consideration at the time of such Asset Sale at least equal to the fair
market value (evidenced by an Officers' Certificate delivered to the Trustee,
and for Asset Sales having a fair market value or resulting in net proceeds in
excess of $5.0 million, evidenced by a resolution of the Board of Directors set

delivered to the Trustee) of the assets sold or otherwise disposed of and (y) at
least 75% of the consideration therefor received by the Company or such
Restricted Subsidiary is in the form of cash or like-kind assets (in each case
as determined in good faith by the Company, evidenced by a resolution of the
Board of Directors and certified by an Officers' Certificate filed with the
Trustee); provided, however, that the amount of (A) any liabilities (as shown on
the Company's or such Restricted Subsidiary's most recent balance sheet or in
the notes thereto) of the Company or such Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Notes or any Subsidiary
Guarantee) that are assumed by the transferee of any such assets and (B) any
notes or other obligations received by the Company or such Restricted Subsidiary
from such transferee that are immediately converted by the Company or such
Restricted Subsidiary into cash (to the extent of the cash received) or Cash
Equivalents, shall be deemed to be cash for purposes of this provision; and
provided, further, that the 75% limitation referred to in the foregoing clause
(y) shall not apply to any Asset Sale in which the cash portion of the
consideration received therefrom is equal to or greater than what the after-tax
proceeds would have been had such Asset Sale complied with the aforementioned
75% limitation. A transfer of assets or issuance of Equity Interests by the
Company to a Wholly Owned Restricted Subsidiary or by a Wholly Owned Restricted
Subsidiary to the Company or to another Wholly Owned Restricted Subsidiary will
not be deemed to be an Asset Sale.

   Within 360 days of any Asset Sale, the Company may, at its option, apply an
amount equal to the Net Proceeds from such Asset Sale either (a) to permanently
reduce Senior Debt, or (b) to an investment in a Restricted Subsidiary or in
another business or capital expenditure or other long-term/tangible assets, in
each case, in the same line of business as the Company or any of its Restricted
Subsidiaries was engaged in on the date of the Indenture or in businesses
similar or reasonably related thereto. Pending the final application of any such
Net Proceeds, the Company may temporarily reduce Senior Bank Debt or otherwise
invest such Net Proceeds in any manner that is not prohibited by the Indenture.
Any Net Proceeds from such Asset Sale that are not applied or invested as
provided in the first sentence of this paragraph will be deemed to constitute
"Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $5.0
million, the Company shall make an offer to all Holders of Notes (an "Asset Sale
Offer") to purchase the maximum principal amount of Notes that may be purchased
out of the Excess Proceeds, at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase, in accordance with the procedures set forth in the Indenture.
To the extent that the aggregate amount of Notes tendered pursuant to an Asset
Sale Offer is less than the Excess Proceeds, the Company may use any remaining
Excess Proceeds for general corporate purposes. If the aggregate principal
amount of Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes to be purchased on a pro rata
basis. Upon completion of such offer to purchase, the amount of Excess Proceeds
shall be reset at zero.

Selection and Notice

   If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate, provided
that no Notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of Notes to be redeemed at its registered
address. 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 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 the redemption date, interest
will cease to accrue on Notes or portions of them called for redemption.

Certain Covenants


   Restricted Payments

   
   The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly: (a) declare or pay
any dividend or make any distribution on account of the Company's or any of its
Restricted Subsidiaries' Equity Interests (other than dividends or distributions
payable in Equity Interests (other than Disqualified Stock) of the Company or
such Restricted Subsidiary or dividends or distributions payable to the Company
or any Restricted Subsidiary); (b) purchase, redeem or otherwise acquire or
retire for value 
    

                                       67


any Equity Interests of the Company or any Restricted Subsidiary or other
Affiliate of the Company (other than any such Equity Interests owned by the
Company or any Restricted Subsidiary); (c) purchase, redeem or otherwise acquire
or retire prior to scheduled maturity for value any Indebtedness that is
subordinated in right of payment to the Notes or (d) make any Investment other
than a Permitted Investment (all such payments and other actions set forth in
clauses (a) through (d) above being collectively referred to as "Restricted
Payments"), unless, at the time of such Restricted Payment:

       (i) no Default or Event of Default shall have occurred and be
   continuing or would occur as a consequence thereof; and

      (ii) the Company would, at the time of such Restricted Payment and after
   giving pro forma effect thereto, have been permitted to incur at least $1.00
   of additional Indebtedness pursuant to the test set forth in the first
   paragraph of the covenant entitled "Incurrence of Indebtedness and Issuance
   of Preferred Stock;" and

     (iii) such Restricted Payment, together with the aggregate of all other
   Restricted Payments made by the Company and its Restricted Subsidiaries after
   the date of the Indenture is less than (x) the cumulative EBITDA of the
   Company, minus 1.75 times the cumulative Consolidated Interest Expense of the
   Company, in each case for the period (taken as one accounting period) from
   June 30, 1996, to the end of the Company's most recently ended fiscal quarter
   for which internal financial statements are available at the time of such
   Restricted Payment, plus (y) the aggregate net Equity Proceeds received by
   the Company from the issuance or sale since the date of the Indenture of
   Equity Interests of the Company or of debt securities of the Company that
   have been converted into such Equity Interests (other than Equity Interests
   or convertible debt securities sold to a Restricted Subsidiary of the Company
   and other than Disqualified Stock or debt securities that have been converted
   into Disqualified Stock), plus (z) $2.0 million.

   
   The foregoing provisions will not prohibit (A) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (B) the redemption, repurchase, retirement or other acquisition or
retirement for value of any Equity Interests of the Company in exchange for, or
with the net cash proceeds of, the substantially concurrent sale (other than to
a Restricted Subsidiary of the Company) of other Equity Interests of the Company
(other than any Disqualified Stock); (C) the defeasance, redemption, repurchase,
retirement or other acquisition or retirement for value of Indebtedness that is
subordinated or pari passu in right of payment to the Notes in exchange for, or
with the net cash proceeds of, a substantially concurrent issuance and sale
(other than to a Restricted Subsidiary of the Company) of Equity Interests of
the Company (other than Disqualified Stock); (D) the defeasance, redemption,
repurchase, retirement or other acquisition or retirement for value of
Indebtedness that is subordinated or pari passu in right of payment to the Notes
in exchange for, or with the net cash proceeds of, a substantially concurrent
issue and sale (other than to the Company or any of its Restricted Subsidiaries)
of Refinancing Indebtedness; (E) the repurchase of any Indebtedness subordinated
or pari passu in right of payment to the Notes at a purchase price not greater
than 101% of the principal amount of such Indebtedness in the event of a Change
of Control in accordance with provisions similar to the "Change of Control"
covenant, provided that prior to or contemporaneously with such repurchase the
Company has made the Change of Control Offer as provided in such covenant with
respect to the Notes and has repurchased all Notes validly tendered for payment
in connection with such Change of Control Offer; (F) the prepayment of the
Chrysler Notes, together with premium and interest thereon; (G) the prepayment
of $450,000 of junior subordinated notes issued by the Company in connection
with a 1990 acquisition, together with interest thereon; and (H) additional
payments to current or former employees or directors of the Company for
repurchases of stock, stock options or other equity interests, provided that the
aggregate amount of all such payments under this clause (H) does not exceed
$500,000 in any year and $2.0 million in the aggregate. 
    

   The Restricted Payments described in clauses (B), (C), (E) and (H) of the
immediately preceding paragraph will be Restricted Payments that will be
permitted to be taken in accordance with such paragraph but will reduce the
amount that would otherwise be available for Restricted Payments under clause
(iii) of the first paragraph of this section, and the Restricted Payments
described in clauses (A), (D), (F) and (G) of the immediately preceding
paragraph will be Restricted Payments that will be permitted to be taken in
accordance with such paragraph and will not reduce the amount that would
otherwise be available for Restricted Payments under clause (iii) of the first
paragraph of this section.

   If an Investment results in the making of a Restricted Payment, the aggregate
amount of all Restricted Payments deemed to have been made as calculated under
the foregoing provision will be reduced by the amount of any net

                                       68


reduction in such Investment (resulting from the payment of interest or
dividends, loan repayment, transfer of assets or otherwise) to the extent such
net reduction is not included in the Company's EBITDA; provided, however, that
the total amount by which the aggregate amount of all Restricted Payments may be
reduced may not exceed the lesser of (a) the cash proceeds received by the
Company and its Restricted Subsidiaries in connection with such net reduction
and (b) the initial amount of such Investment.

   If the aggregate amount of all Restricted Payments calculated under the
foregoing provision includes an Investment in an Unrestricted Subsidiary or
other Person that thereafter becomes a Restricted Subsidiary, such Investment
will no longer be counted as a Restricted Payment for purposes of calculating
the aggregate amount of Restricted Payments. For the purpose of making any
calculations under the Indenture, (a) an Investment will include the fair market
value of the net assets of any Restricted Subsidiary at the time that such
Restricted Subsidiary is designated an Unrestricted Subsidiary and will exclude
the fair market value of the net assets of any Unrestricted Subsidiary that is
designated as a Restricted Subsidiary, (b) any property transferred to or from
an Unrestricted Subsidiary will be valued at fair market value at the time of
such transfer, provided that, in each case, the fair market value of an asset or
property is as determined by the Board of Directors in good faith, and (c)
subject to the foregoing, the amount of any Restricted Payment, if other than
cash, will be determined by the Board of Directors, whose good faith
determination will be conclusive.

   The Board of Directors may designate a Restricted Subsidiary to be an
Unrestricted Subsidiary in compliance with the covenant entitled "Unrestricted
Subsidiaries." Upon such designation, all outstanding Investments by the Company
and its Restricted Subsidiaries (except to the extent repaid in cash) in the
Subsidiary so designated will be deemed to be Restricted Payments made at the
time of such designation and will reduce the amount available for Restricted
Payments under the first paragraph of this covenant. Such designation will only
be permitted if such Restricted Payment would be permitted at such time and if
such Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. 

   Incurrence of Indebtedness and Issuance of Preferred Stock

   The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guaranty or otherwise become directly or indirectly liable with respect
to (collectively, "incur") any Indebtedness (including Acquired Debt) and that
the Company will not permit any of its Restricted Subsidiaries to issue any
shares of preferred stock; provided, however, that the Company may incur
Indebtedness and may permit a Restricted Subsidiary to incur Indebtedness if at
the time of such incurrence and after giving effect thereto the Leverage Ratio
would be less than 6.0 to 1.0.

   The foregoing limitations will not apply to (a) the incurrence by the
Company or any Restricted Subsidiary of Senior Bank Debt in an aggregate
amount not to exceed $25.0 million at any one time outstanding, (b) the
issuance by the Restricted Subsidiaries of Subsidiary Guarantees, (c) the
incurrence by the Company and its Restricted Subsidiaries of the Existing
Indebtedness, (d) the issuance by the Company of the Notes, (e) the
incurrence by the Company and its Restricted Subsidiaries of Capital Lease
Obligations and/or additional Indebtedness constituting purchase money
obligations up to an aggregate of $2.5 million at any one time outstanding,
provided that the Liens securing such Indebtedness constitute Permitted
Liens, (f) the incurrence of Indebtedness between (i) the Company and its
Restricted Subsidiaries and (ii) the Restricted Subsidiaries, (g) Hedging
Obligations that are incurred for the purpose of fixing or hedging interest
rate risk with respect to any floating rate Indebtedness that is permitted by
the terms of the Indenture to be outstanding, (h) the incurrence by the
Company and its Restricted Subsidiaries of Indebtedness arising out of
letters of credit, performance bonds, surety bonds and bankers' acceptances
incurred in the ordinary course of business up to an aggregate of $2.0
million at any one time outstanding, (i) the incurrence by the Company and
its Restricted Subsidiaries of Indebtedness consisting of guarantees,
indemnities or obligations in respect of purchase price adjustments in
connection with the acquisition or disposition of assets, including, without
limitation, shares of Capital Stock, and (j) the incurrence by the Company
and its Restricted Subsidiaries of Refinancing Indebtedness issued in
exchange for, or the proceeds of which are used to repay, redeem, defease,
extend, refinance, renew, replace or refund, Indebtedness referred to in
clauses (b) through (e) above, and this clause (j).

   Liens

   The Indenture will provide that neither the Company nor any of its Restricted
Subsidiaries may directly or indirectly create, incur, assume or suffer to exist
any Lien (other than a Permitted Lien) upon any property or assets

                                       69


now owned or hereafter acquired, or any income, profits or proceeds therefrom,
or assign or otherwise convey any right to receive income therefrom, unless (a)
in the case of any Lien securing any Indebtedness that is subordinate to the
Notes, the Notes are secured by a Lien on such property, assets or proceeds that
is senior in priority to such Lien and (b) in the case of any other Lien, the
Notes are equally and ratably secured with the obligation or liability secured
by such Lien. 

   Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

   The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (a) (i) pay dividends or make any
other distributions to the Company or any of its Restricted Subsidiaries (A) on
its Capital Stock or (B) with respect to any other interest or participation in,
or measured by, its profits, or (ii) pay any Indebtedness owed to the Company or
any of its Restricted Subsidiaries, (b) make loans or advances to the Company or
any of its Restricted Subsidiaries or (c) transfer any of its properties or
assets to the Company or any of its Restricted Subsidiaries, except for such
encumbrances or restrictions existing under or by reason of (1) Existing
Indebtedness, (2) the Credit Agreement as in effect as of the date of the
Indenture, and any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancing thereof, provided that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings are no more restrictive in the
aggregate with respect to such dividend and other payment restrictions than
those contained in the Credit Agreement as in effect on the date of the
Indenture, (3) the Indenture and the Notes, (4) applicable law, (5) any
instrument governing Indebtedness or Capital Stock of a Person acquired by the
Company or any of its Restricted Subsidiaries as in effect at the time of such
acquisition (except to the extent such Indebtedness was incurred in connection
with or in contemplation of such acquisition), which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person, so acquired,
provided that the EBITDA of such Person is not taken into account in determining
whether such acquisition was permitted by the terms of the Indenture, (6)
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices, (7) restrictions on the
transfer of property subject to purchase money or Capital Lease Obligations
otherwise permitted by clause (e) of the covenant entitled "Incurrence of
Indebtedness and Issuance of Preferred Stock," or (8) permitted Refinancing
Indebtedness, provided that the restrictions contained in the agreements
governing such Refinancing Indebtedness are no more restrictive in the aggregate
than those contained in the agreements governing the Indebtedness being
refinanced. 

   Merger, Consolidation, or Sale of Assets

   
   The Indenture will provide that the Company may not consolidate or merge with
or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its properties or assets in one or more related transactions, to another
Person unless: (a) the Company is the surviving corporation or the Person formed
by or surviving any such consolidation or merger (if other than the Company) or
to which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made is a corporation organized or existing under the laws of
the United States, any state thereof or the District of Columbia; (b) the Person
formed by or surviving any such consolidation or merger (if other than the
Company) or the Person to which such sale, assignment, transfer, lease,
conveyance or other disposition shall have been made assumes all the obligations
of the Company under the Notes and the Indenture pursuant to a supplemental
indenture in a form reasonably satisfactory to the Trustee; (c) immediately
after such transaction no Default or Event of Default exists; and (d) the
Company or any Person formed by or surviving any such consolidation or merger,
or to which such sale, assignment, transfer, lease, conveyance or other
disposition shall have been made, will, at the time of such transaction and
after giving pro forma effect thereto, be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the test set forth in the first paragraph of
the covenant entitled "Incurrence of Indebtedness and Issuance of Preferred
Stock." 
    

   Transactions with Affiliates 

   The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, sell, lease, transfer or otherwise dispose of
any of its properties or assets to, or purchase any property or assets from, or
enter into any contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of,

                                       70


   
any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (a)
such Affiliate Transaction is on terms that are no less favorable to the Company
or the relevant Restricted Subsidiary than those that would have been obtained
in a comparable transaction by the Company or such Restricted Subsidiary with a
non-Affiliated Person and (b) the Company delivers to the Trustee (i) with
respect to any Affiliate Transaction involving aggregate payments in excess of
$1.0 million, a resolution of the Board of Directors set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with clause (a)
above and such Affiliate Transaction is approved by a majority of the
disinterested members of the Board of Directors and (ii) with respect to any
Affiliate Transaction involving aggregate payments in excess of $5.0 million, an
opinion as to the fairness to the Company or such Restricted Subsidiary from a
financial point of view issued by an investment banking firm of national
standing; provided, however, that (A) any employment agreement entered into by
the Company or any of its Restricted Subsidiaries in the ordinary course of
business and consistent with the past practice of the Company or such Restricted
Subsidiary, (B) transactions between or among the Company and/or its Restricted
Subsidiaries, (C) transactions permitted by the provisions of the Indenture
described above under the covenant entitled "Restricted Payments" and (D) the
grant of stock, stock options or other equity interests to employees and
directors of the Company in accordance with duly adopted Company stock grant,
stock option and similar plans, in each case, shall not be deemed Affiliate
Transactions; and further provided that (1) the provisions of clause (b) shall
not apply to sales of inventory by the Company or any Restricted Subsidiary to
any Affiliate in the ordinary course of business and (2) the provisions of
clause (b) (ii) shall not apply to loans or advances to the Company or any
Restricted Subsidiary from, or equity investments in the Company or any
Restricted Subsidiary by, any Affiliate to the extent permitted by the
provisions of the Indenture described above under the covenant entitled
"Incurrence of Indebtedness and Issuance of Preferred Stock." 
    

   Certain Senior Subordinated Debt 

   The Indenture will provide that (a) the Company will not incur any
Indebtedness that is subordinated or junior in right of payment to any Senior
Debt of the Company and senior in any respect in right of payment to the
Notes, and (b) the Company will not permit any Restricted Subsidiary to incur
any Indebtedness that is subordinated or junior in right of payment to its
Senior Debt and senior in any respect in right of payment to its Subsidiary
Guarantee.

   Additional Subsidiary Guarantees

   The Indenture will provide that if any entity (other than an Excluded
Restricted Subsidiary) shall become a Restricted Subsidiary after the date of
the Indenture, then such Restricted Subsidiary shall execute a Subsidiary
Guarantee and deliver an opinion of counsel with respect thereto, in accordance
with the terms of the Indenture.

   The Indenture will provide that no Restricted Subsidiary may consolidate with
or merge with or into (whether or not such Restricted Subsidiary is the
surviving Person), another Person (other than the Company) whether or not
affiliated with such Restricted Subsidiary unless (a) subject to the provisions
of the following paragraph, the Person formed by or surviving any such
consolidation or merger (if other than such Restricted Subsidiary) assumes all
the obligations of such Restricted Subsidiary under its Subsidiary Guaranty, if
any, pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Trustee; (b) immediately after giving effect to such
transaction, no Default or Event of Default exists; and (c) such Restricted
Subsidiary, or any Person formed by or surviving any such consolidation or
merger, would be permitted to incur, immediately after giving effect to such
transaction, at least $1.00 of additional Indebtedness pursuant to the test set
forth in the first paragraph of the covenant entitled "Incurrence of
Indebtedness and Issuance of Preferred Stock."

   The Indenture will provide that in the event of (a) a sale or other
disposition of all of the assets of any Restricted Subsidiary, by way of merger,
consolidation or otherwise, (b) a sale or other disposition of all of the
capital stock of any Restricted Subsidiary, or (c) the designation of a
Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the terms
of the covenant entitled "Unrestricted Subsidiaries," then such Subsidiary (in
the event of a sale or other disposition, by way of such a merger, consolidation
or otherwise, of all of the capital stock of such Restricted Subsidiary or in
the event of the designation of such Restricted Subsidiary as an Unrestricted
Subsidiary) or the corporation acquiring the property (in the event of a sale or
other disposition of all of the assets of such Restricted Subsidiary) will be
released and relieved of any obligations under its Subsidiary Guarantee;
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of the Indenture. See "Redemption or
Repurchase at Option of Holders--Asset Sales."

                                       71


   Unrestricted Subsidiaries

   The Board of Directors may designate any Subsidiary (including any Restricted
Subsidiary or any newly acquired or newly formed Subsidiary) to be an
Unrestricted Subsidiary so long as: (i) neither the Company nor any Restricted
Subsidiary is directly or indirectly liable for any Indebtedness of such
Subsidiary; (ii) no default with respect to any Indebtedness of such Subsidiary
would permit (upon notice, lapse of time or otherwise) any holder of any other
Indebtedness of the Company or any Restricted Subsidiary to declare a default on
such other Indebtedness or cause the payment thereof to be accelerated or
payable prior to its stated maturity; (iii) any Investment in such Subsidiary
deemed to be made as a result of designating such Subsidiary an Unrestricted
Subsidiary will not violate the provisions of the covenant entitled "Restricted
Payments;" (iv) neither the Company nor any Restricted Subsidiary has a
contract, agreement, arrangement, understanding or obligation of any kind,
whether written or oral, with such Subsidiary other than (A) those that might be
obtained at the time from Persons who are not Affiliates of the Company or (B)
administrative, tax sharing and other ordinary course contracts, agreements,
arrangements and understandings or obligations entered into in the ordinary
course of business; and (v) neither the Company nor any Restricted Subsidiary
has any obligation to subscribe for additional shares of Capital Stock or other
Equity Interests in such Subsidiary, or to maintain or preserve such
Subsidiary's financial condition or to cause such Subsidiary to achieve certain
levels of operating results other than as permitted under the covenant entitled
"Restricted Payments." Notwithstanding the foregoing, the Company may not
designate as an Unrestricted Subsidiary any Subsidiary which, on the date of the
Indenture, is a Significant Subsidiary, and may not sell, transfer or otherwise
dispose of any properties or assets of any such Significant Subsidiary to an
Unrestricted Subsidiary, other than in the ordinary course of business.

   The Board of Directors may designate any Unrestricted Subsidiary as a
Restricted Subsidiary; provided that such designation will be deemed to be an
incurrence of Indebtedness by a Restricted Subsidiary of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation will only
be permitted if (i) such Indebtedness is permitted under the "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant and (ii) no Default or
Event of Default would occur as a result of such designation.

   
Limitation on Sale and Leaseback Transactions.

   The Company will not, and will not permit any Restricted Subsidiary to, enter
into any Sale and Leaseback Transaction unless (a) the consideration received in
such Sale and Leaseback Transaction is at least equal to the fair market value
of the property sold, as determined by a resolution of the Board of Directors of
the Company, and (b) the Company or such Restricted Subsidiary could incurr the
Attributable Indebtedness in respect of such Sale and Leaseback Transaction in
compliance with the covenant entitled "Incurrence of Indebtedness and Issuance
of Preferred Stock."
    

   Reports

   Whether or not required by the rules and regulations of the Securities and
Exchange Commission (the "Commission"), so long as any Notes are outstanding,
the Company will furnish to the Holders of Notes (a) all quarterly and annual
financial information that would be required to be contained in a filing with
the Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and, with respect to the annual information only, a
report thereon by the Company's certified independent accountants and (b) all
financial information that would be required to be included in a Form 8-K filed
with the Commission if the Company were required to file such reports. In
addition, whether or not required by the rules and regulations of the
Commission, the Company will file a copy of all such information and reports
with the Commission for public availability (unless the Commission will not
accept such a filing) and make such information available to investors who
request it in writing.

Events of Default and Remedies

   The Indenture will provide that each of the following constitutes an Event of
Default: (a) default for 30 days in the payment when due of interest on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (b) default in payment when due of the principal of or premium, if
any, on the Notes (whether or not prohibited by the subordination provisions of
the Indenture); (c) failure by the Company to comply with the provisions
described under "Change of Control;" (d) failure by the Company or any
Subsidiary Guarantor for 60 days after written notice from the Trustee or
Holders of not less than 25% of the aggregate principal amount of the Notes
outstanding to comply with any of its other agreements in the Indenture, Notes
or the Subsidiary Guarantees; (e) default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries) whether such Indebtedness or guarantee
exists on the date of the Indenture or is created thereafter, if (i) such
default results in the acceleration of such Indebtedness prior to its express
maturity or shall constitute a default in the payment of such Indebtedness at
final maturity of such Indebtedness, and (ii) the principal amount of any such
Indebtedness

                                       72


that has been accelerated or not paid at maturity, when added to the aggregate
principal amount of all other such Indebtedness that has been accelerated or not
paid at maturity, exceeds $5.0 million; (f) failure by the Company or any of its
Restricted Subsidiaries to pay final judgments aggregating in excess of $5.0
million, which judgments remain unpaid, undischarged or unstayed for a period of
60 days; (g) certain events of bankruptcy or insolvency with respect to the
Company or any of its Restricted Subsidiaries that are Significant Subsidiaries;
and (h) except as permitted by the Indenture or the Subsidiary Guarantees, any
Subsidiary Guarantee issued by a Restricted Subsidiary shall be held in any
judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect, or any Restricted Subsidiary or any Person
acting on behalf of any Restricted Subsidiary shall deny or disaffirm in writing
its obligations under its Subsidiary Guarantee.

   If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Notes may declare
all the Notes to be due and payable immediately; provided, however, that if any
Obligation with respect to Senior Bank Debt is outstanding pursuant to the
Credit Agreement upon a declaration of acceleration of the Notes, the principal,
premium, if any, and interest on the Notes will not be payable until the earlier
of (i) the day which is five business days after written notice of acceleration
is received by the Company and the Credit Agent, or (ii) the date of
acceleration of the Indebtedness under the Credit Agreement. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency with respect to the Company or any Restricted
Subsidiary that is a Significant Subsidiary, the principal of, and premium, if
any, and any accrued and unpaid interest on all outstanding Notes will become
due and payable without further action or notice. Holders of the Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. In the
event of a declaration of acceleration of the Notes because an Event of Default
has occurred and is continuing as a result of the acceleration of any
Indebtedness described in clause (e) of the preceding paragraph, the declaration
of acceleration of the Notes shall be automatically annulled if the holders of
any Indebtedness described in clause (e) have rescinded the declaration of
acceleration in respect of such Indebtedness within 30 days of the date of such
declaration and if (i) the annulment of the acceleration of the Notes would not
conflict with any judgment or decree of a competent jurisdiction, and (ii) all
existing Events of Default, except non-payment of principal or interest on the
Notes that became due solely because of the acceleration of the Notes, have been
cured or waived.

   In the case of any Event of Default occurring by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding payment of the premium that the Company would have had to
pay if the Company then had elected to redeem the Notes pursuant to the optional
redemption provisions of the Indenture, an equivalent premium shall also become
and be immediately due and payable to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to , 2004 by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Company with the intention of avoiding the prohibition on redemption of
the Notes prior to , 2004, then the premium specified in the Indenture shall
also become immediately due and payable to the extent permitted by law upon the
acceleration of the Notes.

   The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest on, or the principal of, the Notes. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.

   The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

   No director, officer, employee, incorporator or stockholder of the Company or
any Restricted Subsidiary, as such, shall have any liability for any obligations
of the Company or any Restricted Subsidiary under the Notes, the Subsidiary
Guarantees or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting
a Note and the Subsidiary Guarantees waives and releases

                                       73


all such liability. The waiver and release are part of the consideration for
issuance of the Notes and the Subsidiary Guarantees. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

   The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance") except for (a) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
on such Notes when such payments are due, (b) the Company's obligations with
respect to the Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or
agency for payment and money for security payments held in trust, (c) the
rights, powers, trusts, duties and immunities of the Trustee, and the Company's
obligations in connection therewith and (d) the Legal Defeasance provisions of
the Indenture. In addition, the Company may, at its option and at any time,
elect to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance"), and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership and insolvency events) described under "Events of Default" will no
longer constitute an Event of Default with respect to the Notes.

   In order to exercise either Legal Defeasance or Covenant Defeasance, (a) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in Dollars, non-callable Government Securities,
or a combination thereof, in such amounts as will be sufficient, in the opinion
of a nationally recognized firm of independent public accountants, to pay the
principal of, premium, if any, and interest on the outstanding Notes on the
stated maturity or on the applicable redemption date, as the case may be, of
such principal or installment of principal of, premium, if any, or interest on
the outstanding Notes; (b) in the case of Legal Defeasance, the Company shall
have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date of the Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred; (c) in the
case of Covenant Defeasance, the Company shall have delivered to the Trustee an
opinion of counsel in the United States reasonably acceptable to the Trustee
confirming that the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (d) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit or insofar as Events of
Default from bankruptcy or insolvency events are concerned, at any time in the
period ending on the 91st day after the date of deposit; (e) such Legal
Defeasance or Covenant Defeasance shall not result in a breach or violation of,
or constitute a default under, any material agreement or instrument to which the
Company or any of its Subsidiaries is a party or by which the Company or any of
its Subsidiaries is bound; (f) the Company shall have delivered to the Trustee
an opinion of counsel to the effect that after the 91st day following the
deposit, the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally; (g) the Company shall have delivered to the Trustee an
Officers' Certificate stating that the deposit was not made by the Company with
the intent of preferring the Holders of Notes over the other creditors of the
Company with the intent of defeating, hindering, delaying or defrauding
creditors of the Company or others; and (h) the Company shall have delivered to
the Trustee an Officers' Certificate and an opinion of counsel, each stating
that all conditions precedent provided for relating to the Legal Defeasance or
the Covenant Defeasance have been complied with.

Transfer and Exchange

   A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by
the Indenture. The

                                       74


Company is not required to transfer or exchange any Note selected for
redemption. Also, the Company is not required to transfer or exchange any Note
for a period of 15 days before a selection of Notes to be redeemed.

   The registered Holder of a Note will be treated as the owner of it for all
purposes.

Book-Entry, Delivery and Form

   The Notes will be represented by one or more fully registered global notes
(collectively, the "Global Note"). The Global Note will be deposited upon
issuance with, or on behalf of, The Depository Trust Company, as Depositary (the
"Depositary"), and registered in the name of the Depositary or a nominee of the
Depositary (the "Global Note Registered Owner"). Except as set forth below, the
Global Note may be transferred, in whole and not in part, only to another
nominee of the Depositary or to a successor of the Depositary or its nominee.

   The Depositary has advised the Company that the Depositary is a
limited-purpose trust company created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the clearance
and settlement of transactions in those securities between the Participants
through electronic book-entry changes in accounts of its Participants. The
Participants include securities brokers and dealers (including the
Underwriters), banks, trust companies, clearing corporations and certain other
organizations. Access to the Depositary's systems is also available to other
entities such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly (collectively, the "Indirect Participants"). Persons who are not
Participants may beneficially own securities held by or on behalf of the
Depositary only through the Participants or the Indirect Participants. The
ownership interest and transfer of ownership interest of each actual purchaser
of each security held by or on behalf of the Depositary are recorded on the
records of the Participants and Indirect Participants.

   The Depositary has also advised the Company that, pursuant to procedures
established by it, (i) upon deposit of the Global Note, the Depositary will
credit the accounts of Participants designated by the Underwriters with portions
of the principal amount of the Global Note and (ii) ownership of such interests
in the Global Note will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by the Depositary (with respect to
the Participants) or by the Participants and the Indirect Participants (with
respect to other owners of beneficial interests in the Global Note). The laws of
some states require that certain persons take physical delivery in definitive
form of securities that they own. Consequently, the ability to transfer the
Notes will be limited to that extent.

   Except as provided below, owners of interests in the Global Note will not
have Notes registered in their names, will not receive physical delivery of the
Notes in definitive form and will not be considered the registered owners or
holders thereof under the Indenture for any purpose.

   Payments in respect of the principal of and premium, if any, and interest on
any Notes registered in the name of the Global Note Registered Owner will be
payable by the Trustee to the Global Note Registered Owner in its capacity as
the registered holder under the Indenture. Under the terms of the Indenture, the
Company and the Trustee will treat the persons in whose names the Notes,
including the Global Note, are registered as the owners thereof for the purpose
of receiving such payments and for any and all other purposes whatsoever.
Consequently, neither the Company, the Trustee nor any agent of the Company or
the Trustee has or will have any responsibility or liability for (i) any aspect
of the Depositary's records or any Participant's records relating to or payments
made on account of beneficial ownership interests in the Global Note, or for
maintaining, supervising or reviewing any of the Depositary's records or any
Participant's records relating to the beneficial ownership interests in the
Global Note or (ii) any other matter relating to the actions and practices of
the Depositary or any of its Participants. The Depositary has advised the
Company that its current practice, upon receipt of any payment in respect of
securities such as the Notes (including principal and interest), is to credit
the accounts of the relevant Participants with the payment on the payment date,
in amounts proportionate to their respective holdings in principal amount of
beneficial interests in the relevant security as shown on the records of the
Depositary. Payments by the Participants and the Indirect Participants to the
beneficial owners of the Notes will be governed by standing instructions and
customary practices and will be the responsibility of the Participants or the
Indirect Participants and will not be the responsibility of the Depositary, the
Trustee or the Company. Neither the Company nor the Trustee will be liable for
any delay by the Depositary or any of its Participants in identifying the
beneficial owners of the Notes, and

                                       75


the Company and Trustee may conclusively rely on and will be protected in
relying on instructions from the Global Note Registered Owner for all purposes.

   The Global Note is exchangeable for definitive Notes: (i) if the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary of
the Global Note and the Company thereupon fails to appoint a successor
Depositary; (ii) if the Company, at its option, notifies the Trustee in writing
that it elects to cause the issuance of the Notes in definitive registered form;
or (iii) if there shall have occurred and be continuing an Event of Default or
any event which after notice or lapse of time or both would be an Event of
Default with respect to the Notes. Such definitive Notes shall be registered in
the names of the owners of the beneficial interests in the Global Note as
provided by the Participants. Upon issuance of the Notes in definitive form, the
Trustee is required to register the Notes in the name of, and cause the Notes to
be delivered to, the person or persons (or the nominee thereof) identified as
the beneficial owners as the Depositary shall direct.

   Settlement for purchases of beneficial interests in the Global Note upon the
original issuance thereof will be required to be made by wire transfer in
immediately available funds. Payments in respect of the Notes represented by the
Global Note (including principal, premium, if any, and interest) will be made by
wire transfer in immediately available funds to the accounts specified by the
Global Note Registered Owner. With respect to the definitive Notes, the Company
will make all payments of principal, premium, if any, and interest by wire
transfer in immediately available funds to the accounts specified by the Holders
thereof or, if no such account is specified, by mailing a check to such Holder's
registered address. Secondary trading in long-term notes of corporate issuers is
generally settled in clearing-house or next-day funds. In contrast, the
beneficial interests in the Global Note are expected to trade in the
Depositary's Same-Day Funds Settlement System, in which secondary market trading
activity in those beneficial interests would be required by the Depositary to
settle in immediately available funds. There is no assurance as to the effect,
if any, that settlement in immediately available funds would have on trading
activity in such beneficial interests.

Amendment, Supplement and Waiver

   Except as provided in the next two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding (including
consents obtained in connection with a tender offer or exchange offer for
Notes), and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes (including consents
obtained in connection with a tender offer or exchange offer for Notes).

   Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder of Notes): (a) reduce
the principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver; (b) reduce the principal of or change the fixed maturity
of any Note or alter the provisions with respect to the redemption of the Notes
in a manner adverse to the Holders of the Notes; (c) reduce the rate of or
change the time for payment of interest on any Note; (d) waive a Default or
Event of Default in the payment of principal of or premium, if any, or interest
on the Notes (except a rescission of acceleration of the Notes by the Holders of
at least a majority in aggregate principal amount of the then outstanding Notes
and a waiver of the payment default that resulted from such acceleration); (e)
make any Note payable in money other than that stated in the Notes; (f) make any
change in the provisions of the Indenture relating to waivers of past Defaults
or the rights of Holders of Notes to receive payments of principal of or
premium, if any, or interest on the Notes; (g) waive a redemption payment with
respect to any Note (other than a payment required by one of the covenants
described above under the caption "Repurchase at the Option of Holders"); (h)
except pursuant to the Indenture, release any Restricted Subsidiary from its
obligations under its Subsidiary Guarantee, or change any Subsidiary Guarantee
in any manner that would materially adversely affect the Holders; or (i) make
any change in the foregoing amendment and waiver provisions.

   Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company's obligations to Holders of the Notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights under

                                       76


the Indenture of any such Holder, or to comply with requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act.

Concerning the Trustee

   The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.

   The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of Notes, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.

   Anyone who receives this Prospectus may obtain a copy of the Indenture
without charge by writing to Iron Mountain Incorporated, 745 Atlantic Avenue,

obligation and (b) an agreement, direct or indirect, contingent or otherwise,
the practical effect of which is to assure in any way the payment or performance

fixed repurchase price will be calculated in accordance with the terms of such

such reported sale takes place on such day, the average of the closing bid and
asked prices regular way for such day, in each case on the principal national
securities exchange on which such Equity Interests are listed or admitted to
trading (which shall be the national securities exchange on which the greatest

trading days), or (b) if such Equity Interests are not listed or admitted to

   The Company intends to replace the Credit Agreement with the New Credit
Facility. The following description is based upon the current draft credit
agreement relating to the New Credit Facility. No assurances can be given that
the Company will enter into the New Credit Facility on these or any other terms.
The Offering is not conditioned on the closing of the New Credit Facility. 
    
   
   The New Credit Facility will be a $100 million revolving credit facility with
up to $2 million of availability for letters of credit. The New Credit Facility
will terminate on September 30, 2001, at which time all outstanding revolving
credit loans and other amounts payable thereunder will become due. Borrowings
under the New Credit Facility may be used to finance possible future
acquisitions, as well as for working capital and general corporate purposes. As
with the Credit Agreement, the Company's obligations under the New Credit
Facility will be guaranteed by substantially all of the Company's subsidiaries;
however, unlike the Credit Agreement, the New Credit Facility will be secured
only by the pledge of the stock of such subsidiaries. Prepayments of outstanding
borrowings under the New Credit Facility will be required in certain
circumstances out of the proceeds of certain insurance payments, condemnations,
issuances of indebtedness and asset dispositions. 
    
   
   The New Credit Facility will permit the Company to elect from time to time,
as to all or any portion of the borrowings thereunder, an interest rate based

interbank market (the "Eurodollar Rate") for the interest period selected by the
Company, plus, in the case of either (i) or (ii), a margin (the "Applicable
Margin") over the Adjusted Base Rate or the Eurodollar Rate. The Applicable
Margins for loans bearing interest at a rate based upon the Adjusted Base Rate
or the Eurodollar Rate ("Eurodollar Loans"), and commitment fees on the undrawn
portion of the New Credit Facility, will vary based on the Company's 
    

                                       84


achieving and maintaining specified ratios of funded indebtedness (net of cash
and cash equivalents on hand) to EBITDA.

   
   The New Credit Facility will provide for payment by the Company in respect of
letters of credit of: (i) a per annum fee equal to the Applicable Margin for
Eurodollar Loans from time to time in effect; (ii) a fronting fee of 1/4 of 1%;
plus (iii) customary issuing fees and expenses. 
    
   
   The New Credit Facility will contain covenants restricting the ability of the
Company and its subsidiaries to, among other things: (i) declare dividends or
redeem or repurchase capital stock; (ii) make optional payments and
modifications of subordinated and other debt instruments; (iii) incur liens and
engage in sale and leaseback transactions; (iv) make loans and investments; (v)
incur indebtedness and contingent obligations; (vi) make capital expenditures;
(vii) engage in mergers, acquisitions and asset sales; (viii) enter into
transactions with affiliates; and (ix) make changes in their lines of business.
The Company will also be required to comply with financial covenants with
respect to: (i) a maximum leverage ratio; (ii) a minimum interest coverage
ratio; and (iii) a minimum fixed charge coverage ratio. The Company will also be
required to make certain customary affirmative covenants. 
    
   
   Events of default under the New Credit Facility will include: (i) the
Company's failure to pay principal or interest when due; (ii) the Company's
material breach of any covenant, representation or warranty contained in the
loan documents; (iii) customary cross-default provisions; (iv) events of
bankruptcy, insolvency or dissolution of the Company or its subsidiaries; (v)
the levy of certain judgments against the Company, its subsidiaries or their
assets; (vi) certain adverse events under ERISA plans of the Company or its
subsidiaries; (vii) the actual or asserted invalidity of security documents or
guarantees of the Company or its subsidiaries; (viii) a change of control of the
Company; and (ix) the creation of certain environmental liabilities. 
    

                          DESCRIPTION OF CAPITAL STOCK

   The Company's authorized capital stock consists of 13,000,000 shares of
Common Stock, 1,000,000 shares of Nonvoting Common Stock, $.01 par value per
share (the "Nonvoting Common Stock"), and 2,000,000 shares of Preferred Stock,
$.01 par value per share. On September 3, 1996, 9,627,141 shares of Common Stock
were outstanding and 500,000 shares of Nonvoting Common Stock were outstanding.

   Holders of shares of Common Stock are entitled to one vote per share for each
matter submitted to the stockholders of the Company without cumulative voting
rights in the election of Directors. Holders of Nonvoting Common Stock have no
right to vote on any matter voted on by the stockholders of the Company, except
as may otherwise be provided by law. In all other respects (other than as to
convertibility), the rights of holders of the Common Stock and the Nonvoting
Common Stock are identical. Shares of Nonvoting Common Stock are convertible, at
any time at the option of the holder, on a share-for-share basis into shares of
Common Stock without the payment of any additional consideration; provided that
the conversion of any shares of Nonvoting Common Stock by a "bank holding
company" under the Bank Holding Company Act of 1956, as amended, or an affiliate
thereof is prohibited if the conversion of the total number of shares of
Nonvoting Common Stock held by such holder would cause it to be in violation of
such Act.

   The 2,000,000 authorized and unissued shares of Preferred Stock may be issued
with such designations, preferences, limitations and relative rights as the
Board of Directors may authorize including, but not limited to: (i) the
distinctive designation of each series and the number of shares that will
constitute such series; (ii) the voting rights, if any, of shares of such
series; (iii) the dividend rate on the shares of such series, any restriction,
limitation or condition upon the payment of such dividends, whether dividends
shall be cumulative, and the dates on which dividends are payable; (iv) the
prices at which, and the terms and conditions on which, the shares of such
series may be redeemed, if such shares are redeemable; (v) the purchase or
sinking fund provisions, if any, for the purchase or redemption of shares of
such series; (vi) any preferential amount payable upon shares of such series in
the event of the liquidation, dissolution or winding-up of the Company or the
distribution of its assets; and (vii) the price or rates of conversion at which,
and the terms and conditions on which the shares of such series may be converted
into other securities, if such shares are convertible. Although the Company has
no present intention to issue shares of Preferred Stock, the issuance of
Preferred Stock, or the issuance of rights to purchase such shares, could
discourage an unsolicited acquisition proposal and the rights of holders of
Common Stock will be subject to, and may be adversely affected by, the rights of
holders of any Preferred Stock that may be issued in the future.

   The Underwriting Agreement provides that the obligations of the several
Underwriters are subject to certain conditions precedent, including the approval
of certain legal matters by counsel. The Company and the Guarantors have agreed
to indemnify the Underwriters against certain liabilities and expenses,
including liabilities under the Securities Act or to contribute to payments that
the Underwriters may be required to make in respect thereof. The nature of the
Underwriters' obligations is such that the Underwriters are committed to
purchase all of the Notes if any of the Notes are purchased.

   The Underwriters have advised the Company that they propose to offer the
Notes directly to the public initially at the public offering price set forth on
the cover page of this Prospectus and to certain dealers at such offering price
less a concession not to exceed % of the principal amount of the Notes. The
Underwriters may allow, and such dealers may reallow, discounts not in excess of
% of the principal amount of the Notes to certain other dealers. After the
initial public offering of the Notes, the offering price and other selling terms
may be changed by the Underwriters.

   The Notes are a new issue of securities, have no established trading market,
will not be listed on any securities exchange or included in the National
Association of Securities Dealers Automated Quotation System and may not be
widely distributed. The Company has been advised by the Underwriters that,
following the completion of this Offering, the Underwriters presently intend to
make a market in the Notes as permitted by applicable laws and regulations. The
Underwriters, however, are under no obligation to do so and may discontinue any
market-making activities at any time at the sole discretion of the Underwriters.
No assurances can be given as to the liquidity of any trading market for the
Notes.

 The accompanying notes are an integral part of these condensed consolidated
                            financial statements.

                           IRON MOUNTAIN INCORPORATED
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                     (In thousands except per share data)
                                 (Unaudited)

1. General

   The interim condensed consolidated financial statements presented herein
have been prepared by Iron Mountain Incorporated ("Iron Mountain" or the
"Company") without audit and, in the opinion of management, reflect all
adjustments of a normal recurring nature necessary for a fair presentation.
Interim results are not necessarily indicative of results for a full year.

   The condensed consolidated balance sheet presented as of December 31,
1995, has been derived from the consolidated financial statements that have
been audited by the Company's independent public accountants. The unaudited
condensed consolidated financial statements have been prepared pursuant to
the rules and regulations of the Securities and Exchange Commission. Certain
information and footnote disclosures normally included in the annual
financial statements prepared in accordance with generally accepted
accounting principles have been omitted pursuant to those rules and
regulations, but the Company believes that the disclosures are adequate to
make the information presented not misleading. The condensed consolidated
financial statements and notes included herein should be read in conjunction
with the consolidated financial statements and notes included in the
Company's Annual Report on Form 10-K for the year ended December 31, 1995.

2. Initial Public Offering of Common Stock

   On February 6, 1996, the Company completed the sale of 2,350 shares of its
common stock in an initial public offering at a price of $16.00 per share.
The proceeds from the public offering were $34,968 after underwriting
discounts and commissions, and $33,302 after other expenses of the offering
totaling $1,666. Such net proceeds were used to retire the redeemable put
warrant for $6,612, to fund acquisitions, to repay debt that had been
incurred to make acquisitions and for working capital.

3. Acquisitions and Dispositions

   During 1995, the Company purchased four records management businesses.
During the six months ended June 30, 1996, the Company purchased six
additional records management businesses. Each of these acquisitions was
accounted for using the purchase method of accounting, and accordingly, the
results of operations for each acquisition have been included in the
consolidated results of the Company from the respective acquisition dates.
The purchase price for the 1996 acquisitions exceeded the underlying fair
value of the net assets acquired by $14,554, which has been assigned to
goodwill and is being amortized over the estimated benefit period of 25
years. Funds used to make the various acquisitions were provided through the
Company's acquisition credit facility and, indirectly, a portion of the net
proceeds of the Company's initial public offering. A summary of the cash
consideration and allocation of the purchase price as of the acquisition
dates are as follows:


                                                               1996

   The following unaudited pro forma information shows the results of the
Company's operations for the year ended December 31, 1995 and the six months
ended June 30, 1996, as though each of the completed acquisitions had

   The pro forma results have been prepared for comparative purposes only and
are not necessarily indicative of the actual results of operations had the
acquisitions taken place as of January 1, 1995 or the results that may occur
in the future. Furthermore, the pro forma results do not give effect to all
cost savings or incremental costs which may occur as a result of the
integration and consolidation of the companies.

4. Long-term Debt

   Long-term debt as of December 31, 1995 and June 30, 1996, is as follows:

                                                     1995       1996

      Long-term Debt, Net of Current Portion ..   $119,296    $115,700
                                                    =======   ========

5. Commitments and Contingencies

Litigation

   During the second quarter of 1996, the Company paid $600 to cover the
uninsured portion of a judgment previously entered by the California Workers
Compensation Board against the Company relating to injuries sustained by a
driver employed by a courier company used at the time by the Company. This
amount had been fully reserved in the second quarter of 1995 and therefore
had no impact on the results of operations for the three and six month
periods ended June 30, 1996.

   Iron Mountain is presently involved as a defendant in various litigation
which has occurred in the normal course of business. Management believes it
has meritorious defenses in all such actions, and in any event, the amount of
damages, if such matters were decided adversely, would not have a material
adverse effect on Iron Mountain's financial condition or results of
operations.

6. Subsequent Events


   Subsequent to June 30, 1996, the Company acquired four records management
businesses for $23,523 in transactions that were accounted for as purchases.

   On August 29, 1996 the Company amended its Credit Agreement to increase its
Acquisition Credit Facility from $50,000 to $55,000.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
 Iron Mountain Incorporated:

We have audited the accompanying consolidated balance sheets of Iron Mountain
Incorporated (a Delaware corporation) and its subsidiaries, as of December
31, 1994 and 1995 and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1995. 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 audits.

We conducted our audits 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 audits provide 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 Iron Mountain Incorporated
and its subsidiaries, as of December 31, 1994 and 1995 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting
principles.

   Minor maintenance costs are expensed as incurred. Major improvements to
the leased buildings are capitalized as leasehold improvements and
depreciated as described above.

   c. Revenue Recognition

   Storage and service revenues are recognized in the month the respective
service is provided. Storage material sales are recognized when shipped to
the customer. Amounts related to future storage for customers where storage
fees are billed in advance are accounted for as deferred income and amortized
over the applicable period. These amounts are included in deferred income in
the accompanying financial statements.

                                     F-14

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)
                    (Amounts in thousands except share data)

   d. Goodwill

   Goodwill reflects the cost in excess of fair value of the net assets of
companies acquired in purchase transactions. Goodwill is amortized using the
straight-line method from the date of acquisition over the expected period to
be benefited, currently estimated at 25 years. The Company assesses the
recoverability of goodwill, as well as other long lived assets based upon
expectations of future undiscounted cash flows in accordance with Statement
of Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long Lived Assets and for Long Lived Assets to be Disposed of." Accumulated
amortization of goodwill was $11,205 and $15,071 as of December 31, 1994 and
1995, respectively.

   e. Deferred Financing Costs

   Deferred financing costs are amortized over the life of the related debt
using the effective interest rate method. As of December 31, 1994 and 1995,
deferred financing costs were $6,271, and $4,688, respectively, and
accumulated amortization of those costs were $4,024, and $2,050,
respectively.

   f. Customer Acquisition Costs

   Costs, net of revenues received for the initial transfer of the records,
related to the acquisition of large volume accounts (accounts consisting of
10,000 or more cartons) are capitalized and amortized for an appropriate
period not exceeding 12 years, unless the customer terminates its
relationship with the Company, at which time the unamortized cost is charged
to expense. However, in the event of such termination, the Company collects
and records as income permanent removal fees that generally equal or exceed
the amount of unamortized customer acquisition costs. As of December 31, 1994
and 1995 those costs were $5,114 and $6,492, respectively, and accumulated
amortization of those costs were $841 and $1,282, respectively.

   g. Deferred Rent

   The Company has entered into various leases for buildings used in the
storage of records. Certain leases have fixed escalation clauses or other
features which require normalization of the rental expense over the life of
the lease resulting in deferred rent being reflected in the accompanying
balance sheets. In addition, the Company has assumed various unfavorable
leases in connection with certain of its acquisitions. The discounted present
value of these lease obligations in excess of market rate at the date of the
acquisition was recorded as a deferred rent liability and is being amortized
over the remaining lives of the respective leases.

   h. Inventories

   Inventories are carried at the lower of cost using the first-in, first-out
basis or market and are comprised primarily of cartons.

   i. Accrued expenses

   Accrued expenses consist of the following:

                                                     December 31,

   j. Net Income (Loss) Per Common Share

   Net income (loss) per common share is computed based on the weighted
average number of common and common stock equivalent shares outstanding
during each period. Common stock equivalents consist of preferred stock that
is convertible into common stock and employee options to purchase common
stock. Pursuant to certain SEC regulations, the calculation of weighted
average shares outstanding assumes the conversion of preferred stock for all
periods presented. The stock options have not been included in the
calculation of common stock equivalents because their dilutive effect was
immaterial.

   k. Use of Estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of assets and liabilities and
the 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.

   l. Cash and Cash Equivalents

   The Company defines cash and cash equivalents to include cash on hand and
cash invested in short-term securities which have original maturities of less
than 90 days.

3. Debt

   Debt consists of the following:



                                                                         December 31,

   During 1994, the Company had a revolving credit facility of $44,625. This
facility along with a $36,000 senior term loan was refinanced on January 31,
1995 under an amended and restated credit agreement (the Credit Agreement).
Interest on the $36,000 senior debt term loan and the $44,625 revolving
credit facility was based, at the Company's option, on a choice of base rates
plus a margin. The margin varied depending upon the base rate selected.

                                     F-16


                           IRON MOUNTAIN INCORPORATED
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)
                    (Amounts in thousands except share data)

   The Credit Agreement is with a syndicate of lenders and provides for four
separate credit facilities representing an aggregate commitment of $125,000
as follows:

                                                              Maturity
                                                     Amount     Date
                                                     ------   --------
        Term Loan A  ............................   $10,000     2000
        Term Loan B  ............................    50,000     2002
        Working Capital Facility  ...............    15,000     2000
        Acquisition Credit Facility  ............    50,000     2002

   Commencing in 1996, Term Loans A and B are payable in quarterly
installments of $625 and $125, respectively. Term Loan B has a balloon
payment due upon maturity of $46,375. The Working Capital Facility is due in
full upon maturity and the Acquisition Credit Facility is payable in eight
quarterly installments equal to one-eighth of the outstanding balance
commencing in 2000.

   Interest rates on all four facilities under the Credit Agreement are
based, at the Company's option, on a choice of base rates plus a margin. The
margin varies for each facility depending upon the base rate selected. The
margins are subject to adjustment after January 1996 based on the Company's
ability to meet certain financial covenant targets. At December 31, 1995, the
effective interest rates for Term Loans A and B were 8.22% and 8.72%,
respectively, and for the Working Capital Facility and Acquisition Credit
Facility were 9.75% and 8.72%, respectively. There is a commitment fee of
1/2% per year on the unused portion of the Working Capital Facility and
Acquisition Credit Facility.

   The $15,000 Chrysler Notes were issued in 1990 and mature in 2000. Annual
principal payments of $5,000 commence in 1998. A warrant was issued in
connection with the Chrysler Notes to which management assigned an initial
value of $750 for financial reporting purposes (see Note 5). The value of the
warrant is being accounted for as an original issue discount of the Chrysler
Notes and is being amortized as interest expense over the life of the loan
using the effective interest rate method. The note is junior only to the
Credit Agreement and has an effective interest rate of 13.7%.

   The Credit Agreement and Chrysler Notes specify certain minimum or maximum
relationships between operating cash flows (earnings before interest, taxes,
depreciation and amortization) and interest, total debt and fixed charges.
There are restrictions on dividends, sales or pledging of assets, capital
expenditures and change in business and ownership; cash dividends are
effectively prohibited. The Company was in compliance with the applicable
provisions of these agreements at December 31, 1995. Loans under the Credit
Agreement are secured by substantially all of the stock and assets of the
Company's subsidiaries, with the exception of a secondary position on two
owned properties encumbered by first mortgages.

   The real estate mortgages consist of an $8,037, 10 year, 11% mortgage
based on 30 year amortization with a balloon payment due October, 2000 and a
$3,000, 8% note that is payable in various installments commencing in 1996
and maturing in November, 2006.

   The Company is required to maintain interest rate protection under the
Credit Agreement. In 1988, the Company entered into an interest rate swap
(which expired in October 1995) whereby the Company paid a fixed interest
rate of 9.28% and received a rate equal to the 3-month LIBOR rate. The
interest was based on the outstanding notional principal amount which was
$2,338 at December 31, 1994. The Company has also purchased two interest rate
caps under which it will receive payments in the event that the three month
LIBOR rate exceeds those specified in the caps. Each cap covers $10,000 of
notional principal amount. One had a rate cap of 6.5% and expired on August
11, 1995 and the other has a rate cap of 7.5% and expires August 12, 1997.

   On March 24, 1995, the Company entered into two three-year interest rate
collar swap transactions. Under these agreements, interest costs for the debt
covered by the notional amount of these contracts will essentially float when
the three-month LIBOR is between 6% and 7.5% but the Company will receive a
payment from the bank in the event that the three month LIBOR interest rate
exceeds 7.5%, or make a payment to the bank if such rate

                                     F-17


                           IRON MOUNTAIN INCORPORATED
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)
                    (Amounts in thousands except share data)

is below 6%. Each transaction covers $10,000 of notional principal amount
which will result in a maximum interest cost (including margin and
transaction costs) of approximately 10.54% and 10.67%, respectively, for the
covered amounts. In the event of non-performance by the counterparty, the
Company would be exposed to additional interest rate risk if the variable
interest rate were to exceed the ceiling (7.5%) under the terms of the swap
agreement.

   Maturities of long-term debt are as follows:

 Year                                            Amount
 ----                                           --------

   Based on the borrowing rates currently available to the Company for loans
with similar terms and average maturities, the Company has estimated the
following fair values for its long-term debt and swap agreements as of
December 31, 1995 as follows:

   The fair value of the various swap agreements is based on the estimated
amount a bank would charge to terminate the various swap agreements.

4. Acquisitions and Dispositions

   During 1994, the Company purchased substantially all of the assets, and
assumed certain liabilities, of three separate records management businesses.
During 1995, the Company purchased substantially all of the assets, subject
to certain liabilities, of four records management businesses. Each of these
acquisitions was accounted for using the purchase method of accounting and
accordingly, the results of operations for each acquisition have been
included in the consolidated results of the Company from the respective
acquisition dates. The excess of the purchase price over the underlying fair
value of the assets and liabilities of each acquisition has been assigned to
goodwill ($2,484 and $26,054 in 1994 and 1995, respectively) and is being
amortized over the estimated benefit period of 25 years. Funds used to make
the various acquisitions were provided through the Company's acquisition
credit facilities. A summary of the cash consideration and allocation of the
purchase price as of the acquisition dates are as follows:

The pro forma results have been prepared for comparative purposes only and
are not necessarily indicative of the actual results of operations had the
acquisitions taken place as of January 1, 1994 or the results that may occur
in the future. Furthermore, the pro forma results do not give effect to all
cost savings or incremental costs which may occur as a result of the
integration and consolidation of the companies.

In 1995, the Company made a decision to sell one of its subsidiaries and has
estimated that the purchase price will be $900 less than the book value of
the assets and related goodwill. Consequently, the Company has recorded an
impairment of the related goodwill in the accompanying statement of
operations for 1995.

5. Common and Preferred Stock and Redeemable Put Warrant

   During 1995, the Company declared a 15.4215-for-1 stock split of the Class
A and Class B Common Stock in the form of a stock dividend payable on
November 29, 1995 to stockholders of record on November 28, 1995. All
weighted average common share and stock related data in the consolidated
financial statements have been retroactively restated to reflect the stock
split.

   The Company has authorized the following eight classes of capital stock as
of December 31, 1995:

                                                       Number of Shares

   Upon consummation of the underwritten public offering of common stock (See
Note 10), all shares of preferred stock were automatically converted into
shares of common stock. The number of common shares received upon conversion
were as follows:

                                      Preferred      Common
                                        --------   ----------

   The preferred stock is entitled to weighted average anti-dilution
protection and receives dividends on a common stock equivalent basis.

In anticipation of the public offering, the Board of Directors approved and
the shareholders ratified a recapitalization plan as follows:

The designation of three new classes of stock:

                                                          Authorized

Common Stock, $0.01 par value  .......................    13,000,000
Nonvoting Common Stock, $0.01 par value  .............     1,000,000

In connection with the issuance of the Chrysler Notes, the Company also
issued a warrant, dated December 14, 1990 (the Warrant), exercisable for
444,385 shares of common stock for nominal consideration upon the occurrence
of certain specified events, including the effectiveness of an underwritten
public offering of the Company's capital stock, and at any time after
December 14, 1995. Chrysler Capital had the right to put (the Put) all or any
part of the Warrant to the Company at any time after December 14, 1995, at
the higher of a formula price based on a specified multiple of the Company's
operating cash flow for the preceding 12 months, subject to certain
adjustments, or fair market value of the Company (the Put Price). The Put was
to terminate upon the consummation of an underwritten public offering which
yielded net proceeds of not less than $10 million to the Company. Chrysler
Capital and the Company reached an agreement pursuant to which Chrysler
Capital would not exercise the Warrant or the Put until April 30, 1996 and
the Company would redeem the Warrant upon completion of the closing of the
public offering (See Note 10). On February 7, 1996, the Warrant was redeemed
for $6,612. This Warrant has been accreted each year using the effective
interest rate method based on the Warrant's estimated redemption value at its
estimated redemption date of February 15, 1996 and is reflected as a
redeemable put warrant in the accompanying balance sheets.

In September, 1991 the Company created a non-qualified stock option plan
pursuant to which up to 444,385 shares of Class A common stock of the Company
can be issued at the discretion of the stock option committee to key
employees, consultants and directors.

The following is a summary of stock option transactions during the applicable
periods:

The stock options were granted at an amount equal to or greater than the fair
market value at the date of grant as determined by the Board of Directors.
There are no shares available for grant under the 1991 plan as of December
31, 1995. The majority of options become exercisable ratably over a period of
five years unless the holder terminates employment. As of December 31, 1995,
175,380 of the options outstanding were exercisable.

Effective November 30, 1995, the Board of Directors approved the adoption of
the 1995 Stock Incentive Plan (the Stock Option Plan), which replaced the
previous stock option plan. A total of 1,000,000 shares of Class A Common
Stock are available for grant as options and other rights under the Stock
Option Plan, including the options issued under the 1991 plan. The number of
options available for grant at December 31, 1995 was 555,615.

6. Income Taxes

   The Company accounts for income taxes in accordance with SFAS No. 109
which requires the recognition of deferred tax assets and liabilities for the
expected tax consequences of temporary differences between the tax and
financial reporting bases of assets and liabilities.

   The tax effects of temporary differences that give rise to significant
portions of the deferred tax assets and deferred tax liabilities are
presented below:

7. Commitments and Contingencies

   a. Leases

   Iron Mountain leases most of its facilities under various operating
leases. A majority of these leases have renewal options of five to ten years
and have either fixed escalation clauses or Consumer Price Index escalation.
The Company also leases equipment under operating and capital leases,
primarily computers which have an average lease life of three years. Trucks
and office equipment are also leased and have remaining lease lives ranging
from one to five years. Rent expense was $12,680, $13,555, and $15,661 for
the years ended December 31, 1993, 1994 and 1995, respectively.

   Minimum future lease payments are as follows:

   b. Litigation

   In 1992, the Company was named co-defendant in a suit alleging personal
injuries sustained in an automobile collision with a driver employed by a
courier company used at the time by Iron Mountain. The courier company
subsequently filed for bankruptcy. In March, 1995, a judgment was entered
against the Company in the Superior Court of the State of California for
County of Los Angeles. The Company has accrued $600 in the accompanying
financial statements which approximates the uninsured portion of the
judgment.

   Iron Mountain is presently involved as a defendant in various litigation
which has occurred in the normal course of business. Management believes it
has meritorious defenses in all such actions, and in any event, the amount of
damages, if such matters were decided adversely, would not have a material
adverse effect on Iron Mountain's financial condition or results of
operations.

   c. Other

   The Company may be responsible for environmental clean-up costs at certain
of its facilities. Estimated costs of $800 to perform the necessary
remediation work are included in other liabilities in the accompanying
balance sheets. In 1994, the Company incurred losses at one of its facilities
in California, resulting from the Northridge earthquake. The Company has
filed a claim for reimbursement with its insurance carrier and has received
partial reimbursement to date, with the balance of $1,400 expected to be
received upon the insurance company's completion of its review of the pending
claim. Management believes the ultimate outcome of the above issues will not
have a material adverse effect on Iron Mountain's financial condition or
results of operations.

8. Related Party Transactions

   a. Rental Arrangements

   Iron Mountain leases space to an affiliated company, Schooner Capital
Corporation (Schooner) for its corporate headquarters located in Boston,
Massachusetts. Accordingly, for the years ended December 31, 1993, 1994 and
1995, Schooner paid Iron Mountain rent totaling $48, $58, and $49,
respectively. Iron Mountain leases one facility from a landlord which is a
related party. Total rental payments for the years ended December 31, 1993,
1994 and 1995 for this facility totaled $88, $88, and $93, respectively. In
the opinion of management, both of these leases were entered into at market
prices and terms.

   b. Long Term Debt

   Iron Mountain is obligated in the amount of $383 on a junior subordinated
note bearing interest at 8%, payable in March, 2000. This note, originally
issued in connection with an acquisition, was purchased by and is now held by
Schooner.

9. Profit Sharing Retirement Plan

   The Company has a defined contribution plan which covers all non-union
employees meeting certain service requirements. Eligible employees may elect
to defer from 1 to 15% of compensation per pay period up to the amount
allowed by the Internal Revenue Code. The Company makes matching
contributions based on the amount of the employee contribution and years of
credited service, according to a schedule as described in the Plan documents.
The Company has expensed $131, $146, and $294, for the years ended
December 31, 1993, 1994 and 1995, respectively.

10. Subsequent Events

   In January and February 1996, the Company acquired three records services
businesses for $10,047 in transactions that will be accounted for as
purchases.

   On February 6, 1996, the Company completed an initial public offering of
its stock. The net proceeds from the public offering of $34,968 were used to
repay $28,313 of indebtedness and interest under the acquisition credit
facility, to retire a warrant of $6,612, and for working capital.

NOTE 4--FEDERAL INCOME TAXES

   The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards Number 109, "Accounting for
Income Taxes". Under the provisions of Statement No. 109, a current tax
liability or asset is recognized for the estimated taxes currently payable or
refundable for the current year and a deferred tax liability or asset is
recognized for the estimated future tax effects attributable to temporary
differences and carryforwards. Temporary differences represent the difference
between the book and tax bases of assets or liabilities that will result in
taxable or deductible amounts in future years when the asset or liability is
recovered or settled.

   Summary of the provision for income tax expense (benefit) for the year
ended June 30, 1995 is as follows:

Currently payable  ...................................    $   457
Deferred  ............................................     (4,595)
Utilization of operating loss carryforward  ..........     59,727
                                                            ------
Provision for income tax expense  ....................    $55,589
                                                            ======

   A reconciliation of income tax at the statutory rate to the Company's
effective rate is as follows:

Computed at the expected statutory rate  .............    38.0%
Officer's life insurance  ............................      .9
Amortization of goodwill  ............................     1.7
Deferred compensation  ...............................     1.7
Other differences  ...................................    (2.5)

NOTE 4--FEDERAL INCOME TAXES -- (Continued)

   For the year ended June 30, 1995, the Company was included in a
consolidated federal income tax return. The Company had carryovers as
follows:

   Carryover                        Amount      Expiration
    ---------------------------    ---------   -----------
   Net operating loss  ........   $2,109,000    2004-2009
   Contributions  .............        5,510    1996-1999

   The deferred tax benefit consisted of the following at June 30, 1995:

 Deferred tax benefit:
  Net operating loss carryforward  ..........    $801,420
  Other temporary differences  ..............       9,011
                                                   -------
                                                  810,431
  Valuation allowance  ......................       -0-
                                                   -------
  Net deferred tax benefit  .................    $810,431
                                                   =======

   Even though the Company has net operating loss carryforwards from fiscal
years ended June 30, 1985 through June 30, 1994, management believes that it
is more likely than not that it will generate taxable income sufficient to
realize the tax benefit associated with net operating loss and tax credit
carryforwards. This belief is based upon, among other factors, expectations
of continued growth in sales and changes in operations, as well as
consideration of available tax planning strategies. Specifically, the Company
has plans to consolidate operations in the DMS business by selling a
warehouse and moving files to an existing leased facility. The sale of the
warehouse facility is expected to result in a significant gain as the
facility's best use, due to its location and structure, is other than
warehouse space. Additionally, the Company has plans to sell the operating
assets of the DMS business at a significant gain. Management believes that no
valuation allowance is appropriate given the current estimates of future
taxable income. If the Company is unable to generate sufficient taxable
income in the future through operating results, or through the sales
discussed in Note 14, increases in the valuation allowance will be required
through a charge to income tax expense.

   At June 30, 1995, a substantial portion of the Company's notes payable
were due within one year. However, as discussed in Note 14, substantially all
of the operating assets of the Company were sold effective November 30, 1995.
The proceeds of this sale were sufficient to pay all of the Company's notes
payable.

Additional Restrictions Required by Long-Term Debt

   The Company, its parent and affiliates entered into loan agreements with
Massachusetts Mutual Life Insurance Company and National Westminster Bank
USA. The affiliated group is required to comply with certain restrictive
covenants which require, among other things, limitations on capital
expenditures and corporate overhead and a deadline for providing audited
financial statements. While the affiliated group was in violation of these
agreements, the two lenders have issued waivers for the covenant violations
as of June 30, 1995.

NOTE 8--TRANSACTIONS WITH RELATED PARTIES

   The Company has various lease and management agreements with affiliates.
The Company's parent, Outdoor West, Inc., charges the Company a management
fee which covers executive management supervision in addition to general
management services which include leasing, accounting, finance, personnel and
general supervision

NOTE 9--UNEARNED INCOME

   Unearned income represents primarily income billed one month in advance
for record storage. Most of this was recognized as income in July, 1995.

NOTE 10--OBLIGATIONS UNDER CAPITAL LEASE

   The Company is the lessee of property under capital leases with
expirations as disclosed in the following table. Assets and liabilities under
capital leases are recorded at the lower of the present value of the minimum
lease payments or the fair value of the asset. The assets are depreciated
over the lower of their related lease terms or their estimated productive
lives. Depreciation of assets under capital leases is included in
depreciation expense for 1995.

   Interest rates on capitalized leases vary and are imputed based on the
lower of the Company's incremental borrowing rate at the inception of each
lease or the lessor's implicit rate of return.

                         NASHVILLE VAULT COMPANY, LTD.
                        (A TENNESSEE LIMITED PARTNERSHIP)
                          NOTES TO FINANCIAL STATEMENTS

1. Nature of Operations

   Nashville Vault Company, Ltd. (the "Partnership") is a limited partnership
formed pursuant to the Uniform Limited Partnership Act of Tennessee on
February 21, 1985 to renovate, own and operate a maximum security facility
containing safe deposit boxes and secured storage vaults in Nashville.

   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
statement and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

2. Summary of Significant Accounting Policies

Cash Equivalents

   The Partnership considers all liquid investments with original maturities
of three months or less to be cash equivalents. At December 31, 1995, cash
equivalents consisted of savings accounts. From time to time during the year,
the Partnership's cash accounts exceeded federally insured limits.

Property and Equipment

   Property and equipment are carried at cost, and such cost is being
recovered using straight-line and accelerated methods of depreciation, with
useful lives of 15 to 31.5 years for building and improvements, 5 to 7 years
for furniture and equipment, and 5 years for vehicles.

Revenue Recognition

   Revenue is recognized when earned. Revenue billed in advance is shown as
deferred revenue.

Advertising Costs

   The Partnership expenses advertising costs as incurred. Advertising costs
were $6,787 in 1995.

Income Tax Status

   Since the entity is a partnership, it is not subject to federal and state
income taxes and, accordingly, no provision for federal and state taxes on
income is required. The partners include their allocable share of the net
income or loss in their respective income tax returns.

3. Convertible Notes Payable

   The 12% convertible notes, payable to certain limited partners, are
convertible into limited partnership units at a conversion price of $12,500
for one limited partnership unit. On January 1, 1996, all convertible notes
were converted into 26 limited partnership units.

4. Employee Benefits

   On January 1, 1994, the Partnership established a 401(k) defined
contribution plan for the benefit of substantially all of its employees,
which allows for both employee and Partnership contributions. The Partnership
contribution consists of a matching contribution of 25 percent of employee
contributions, up to 3.75 percent of eligible employee compensation. The
Partnership contribution to the plan was $3,924 for 1995. This plan was
terminated on December 31, 1995.

                                     F-48


                         NASHVILLE VAULT COMPANY, LTD.
                (A TENNESSEE LIMITED PARTNERSHIP) -- (Continued)

5. Partnership Agreement

   The Agreement of Limited Partnership (as amended) specifies the allocation
of profits, losses, and distributions to be allocated 1% to the General
Partner and 99% to the Investor Limited Partners.

   Under the agreement, the limited partners are not liable for any debts of
the Partnership nor are they required to make any additional capital
contributions.

6. Related Party Transactions

   The Partnership leases the ground on which its building is located from
family members of stockholders of the General Partner and pays real estate
taxes and other related expenses under the lease which expires November 30,
2000. On January 1, 1996, the Partnership exercised an option to purchase the
land for $250,000. Rent expense in 1995 was $29,000.

   The General Partner, USA Vault Corporation, is guaranteed a monthly
management fee for the operation of the Partnership. The fee begins at $1,000
per month increasing to $2,000 and $3,000 monthly when annual gross revenue
exceeds $200,000 and $300,000, respectively. The Partnership incurred
management fees to the General Partner of $32,000 in 1995.

   The Partnership pays fees to a company owned by the president of USA Vault
Corporation for accounting and bookkeeping services. Fees paid totaled
$12,000 for 1995.

7. Major Customer

   Sales from a major customer approximated 10% of sales and 19% of accounts
receivable at December 31, 1995.

8. Subsequent Event

   On January 4, 1996, the Partnership sold, effective January 1, 1996,
substantially all of its operating assets for approximately $3,450,000 to
Iron Mountain Record Management, Inc.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                                  MAY 31, 1996

NOTE 1--NATURE OF BUSINESS


   The accompanying financial statements represent the combined accounts of
Data Archive Services, Inc. and Data Archive Services of Miami, Inc.
(Affiliate). Data Archive Services, Inc. and Affiliate (the Companies) are
records management companies providing storage and related services primarily
in Dade, Broward and Palm Beach Counties.


NOTE 2--SIGNIFICANT ACCOUNTING POLICIES

   a. Principles of Combination


   The financial statements reflect the financial position and results of
operations of the Companies on a combined basis. All significant intercompany
balances and transactions have been eliminated.


   b. Property and Equipment

   Property and equipment are recorded at cost and depreciated using the
straight-line and declining balance methods with the following useful lives:

                                      Years
                                       ------
Leasehold Improvements                14-20
Shelving                               8-33
Vaults and Security Systems            8-10
Office Furniture and Equipment          5-7
Vehicle                                   6

   Expenditures for repairs and maintenance are charged to expense as
incurred. Expenditures for major renewals and betterments, which
significantly extend the useful lives of existing property and equipment, are
capitalized and depreciated. Upon retirement or disposition of property and
equipment, the cost and related accumulated depreciation are removed from the
accounts and any resulting gain or loss is recognized in income.

   c. Allowance for Doubtful Trade Receivables

   Bad debts are accounted for on the reserve method. As at May 31, 1996, no
reserve for doubtful accounts was required.

   d. Revenue Recognition

   Storage and service revenues are recognized in the month the respective
service is provided. Storage material sales are recognized when shipped to
the customer. Amounts related to future storage for customers when storage
fees are billed in advance are accounted for as deferred revenue and
amortized over the applicable period. These amounts are included in deferred
revenue in the accompanying financial statements.

   e. Inventories

   Inventories are carried at the lower of cost using the first-in, first-out
basis, or market and are comprised primarily of boxes.

   f. Cash and Cash Equivalents


   The Companies define cash and cash equivalents to include cash on hand and
cash invested in short-term securities which have original maturities of less
than 90 days.



                                     F-54

g. Financial Statements Estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions which affect the reporting of assets and liabilities as of the
dates of the financial statements and revenues and expenses during the
reporting period. Actual results may differ from these estimates.

h. Income Taxes

   The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 (SFAS No. 109), "Accounting For Income
Taxes". Under SFAS No. 109, an asset and liability approach is required. Such
approach results in the recognition of deferred tax assets and liabilities
for the expected future tax consequences of temporary differences between the
book carrying amounts and the tax basis of assets and liabilities.

NOTE 3--LONG-TERM LIABILITIES

   (A) This obligation is non-cancelable with no offset. Therefore the payoff
       amount, if Data Archive Services, Inc. cancels this agreement, is

operating loss carryforward of $318,682, which will expire in 2011.
Realization of the deferred tax asset of $75,000 associated with the loss
carryforwards is dependent upon the future earnings of this company. Because
of the uncertainty of realization of this asset, a valuation allowance has
been recognized for the entire deferred tax asset.


NOTE 9--FAIR VALUE OF FINANCIAL INSTRUMENTS


   The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of SFAS No. 107,
"Disclosures About Fair Value of Financial Instruments." These estimates have
been determined by the Companies using available market information and
appropriate valuation techniques based on information as of May 31, 1996. As
considerable judgment is inherent in the development of these estimates, they
are not necessarily indicative of the amounts that the companies could
realize in the current market exchange.


   The recorded amounts and fair values are as follows:

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.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1995

1. ORGANIZATION OF THE COMPANY:

Data Storage Systems, Inc. (a California corporation) operates a
records-storage warehouse in San Jose, California.


The Company entered into a merger agreement with Iron Mountain Records
Management, Inc. in November 1995. The merger was effective as of February 29,
1996. Iron Mountain is the surviving entity and the Company became a wholly
owned subsidiary of Iron Mountain.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Cash

   For purposes of the statements of cash flows, the Company considers all
highly liquid investments with an original maturity of 90 days or less to be
cash equivalents.

Equipment and Improvements

   Equipment and improvements are stated at cost and depreciated using the
straight-line method over the estimated useful lives (ranging from three to
seven years) or over the shorter of the estimated useful life of the asset or
its lease term for leasehold improvements. Equipment and improvements consist
of the following:

       Warehouse equipment  .................................   $  931,814
       Office equipment  ....................................       68,006
       Improvements  ........................................       20,942
                                                                   --------
                                                                $1,020,762
                                                                   ========

Revenue Recognition

   Revenue is recognized ratably over the time that the Customer's records
are in storage. Customers are billed one month in advance for storage and in
arrears for service. Advance billings for storage are recorded as deferred
revenue.

Income Taxes

   The Company accounts for income taxes pursuant to the provisions of
Statement of Financial Accounting Standards No. 109 "Accounting for Income
Taxes" (SFAS 109). SFAS 109 requires recognition of deferred tax liabilities
and assets for the expected future tax consequences of events that have been
included in the financial statements or tax returns. Under this method,
deferred tax liabilities and assets are determined using the current
applicable enacted tax rate and provisions of the enacted tax law.

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
the 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.

3. NOTES PAYABLE AND RELATED PARTIES:


   At December 31, 1995, the Company had several notes payable totaling
$993,402 to shareholders with varying interest rates ranging from 10.0% to
18.8%. These notes are payable upon demand. The fair value of the notes

                  NOTES TO FINANCIAL STATEMENTS -- (Continued)

payable does not materially differ from the carrying value. On February 29,
1996, these notes and the related accrued interest were converted to shares
of common stock in connection with the acquisition of the Company by Iron
Mountain Records Management, Inc.

not cumulative.

Liquidation Preference

   In the event of any liquidation, dissolution, or winding up of the
Company, either voluntary or involuntary, distributions to the shareholders
of the Company shall be made in the following manner:

   The holders of the Series C shall be entitled to receive, prior and in
preference to any distribution of any assets or surplus funds of the Company
to the holders of the Series A, Series B or Common Stock, an amount equal to
$0.60 per share for each share of Series C held by them. If the assets and

   The holders of the Series A shall be entitled to receive, prior and in
preference to any distribution of any assets or surplus funds of the Company
to the holders of the Series B or Common Stock, an amount equal to $1.00 per

Preferred Stock based on the number of shares of Common, Series A, B and C
(on an as converted basis) then issued and outstanding.

Conversion

   Each share of Series A, B and C shall be convertible into the number of
shares of Common Stock which results from dividing $1.00 in the case of
Series A and B, and $0.60 in the case of Series C by the conversion price per
share applicable to such series of Preferred Stock at the time of conversion.
The conversion rate is subject to adjustment for anti-dilution as defined in
the Certificate of Incorporation.

   Each share of Series A, B and C shall automatically be converted into
shares of Common Stock immediately upon the closing of the issuance of shares
following the effectiveness of a registration statement under the Securities
Act of 1933 when the net proceeds equal or exceed $5,000,000 and the price
per share of Common Stock is not less than $4.00.

   Additionally, Series B shall automatically be converted into shares of
Common Stock: (1) immediately upon the closing of any sale or sales of its
Preferred Stock when the aggregate gross proceeds equal or exceeds $1,000,000
and the price per share of Preferred Stock is not less than $1.00, (2) the
last day of any fiscal year in which the Company realizes gross revenues of
at least $1,000,000 and (3) the last day of any fiscal year in which the
Company realizes after-tax operating income of at least $200,000. Because of
the pending merger of the Company, no conversion of the Series B took place.

5. COMMITMENTS:

   The Company leases its facility under an operating lease which expires in
December 1997. Future minimum rental payments as of December 31, 1995 under
this lease are $432,000, ($216,000 for 1996 and $216,000 for 1997). Facility
rent expense for the year ended December 31, 1995 was $218,420.

6. INCOME TAXES:

   As of December 31, 1995, the Company had Federal net operating loss
("NOL") carryforwards for tax purposes of approximately $2,538,548 which
expire in fiscal years 2004 and 2008. The Company had a net deferred tax
asset at December 31, 1995 of approximately $1,057,000. Realization of the
deferred tax asset is dependent upon the Company achieving adequate levels of
taxable income. A valuation allowance has been recognized against the entire
net deferred tax asset because of uncertainty of realization of the asset.
The use of the NOL is limited to maximum amounts each year as a result of the
change in control to Iron Mountain.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of Iron Mountain Incorporated:

I have audited the accompanying balance sheet of DataVault Corporation as of
December 31, 1995 and the related statements of income and accumulated
deficit, and cash flows for the year then ended. These financial statements
are the responsibility of the Company's management. My responsibility is to
express an opinion on these financial statements based on my audit.

I conducted my audit in accordance with generally accepted auditing
standards. Those standards require that I 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. I believe that my audit provides a
reasonable basis for my opinion.

In my opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of DataVault Corporation as of
December 31, 1995 and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting
principles.

                          NOTES TO FINANCIAL STATEMENTS
                                DECEMBER 31, 1995

NOTE 1--ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

   Organization--DataVault Corporation (the Company) is a Massachusetts
corporation. The Company provides record storage and management services in
the New England area.

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

   Revenue Recognition--Revenue is recognized when the services are provided.
Amounts related to future storage that have been billed in advance are
recorded as deferred revenue and recognized over the applicable period.

   Plant and Equipment--Plant and equipment are recorded at cost. Maintenance
and repairs are charged to expense and major improvements are capitalized.
Depreciation is computed on the straight line and declining balance methods
over estimated useful lives as follows:

   Building and improvements  ..................      15-31 years
   Furniture and fixtures  .....................          5 years
   Equipment  ..................................          5 years

   Deferred Costs--Deferred financing costs are amortized over the life of
the related debt. Customer acquisition costs related to the initial transfer
of records are amortized over the term of the initial storage agreement.

   Income Taxes--The Company has elected to be taxed as a Small Business
Corporation. Accordingly, net income and other items of Federal and state tax
significance are reported on the income tax returns of the individual
shareholders.

NOTE 2--LONG-TERM DEBT

   During 1993, the Company constructed an addition to the records storage
facility. The Company refinanced the existing mortgage loan in conjunction
with supplemental financing for the addition. The refinanced mortgage will be
paid in monthly installments over a 20 year period. The interest rate will be
9% adjustable every three years with initial monthly payments of $6,361.

   The additional bank mortgage note of $70,001 is due in monthly
installments of $640 over 20 years at an interest rate of 8.75%, adjustable
every three years.

   Additional financing for the records storage facility has been obtained
from Bay Colony Development Corp., a Certified Development Company. This
financing has been funded by debentures issued by the development company and
guaranteed by the Small Business Administration. Monthly payments of $5,290
will be made over 20 years and include interest at 6.359% and a service fee.

   The mortgage notes are secured by land, buildings and business assets of
the Corporation and the personal guaranty of the sole shareholder.

   The equipment notes are payable in monthly installments of approximately
$2,100 over various periods up to five years at interest rates from 8% to
14%. The notes are secured by certain furniture and equipment.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Directors
 Iron Mountain Incorporated:


We have audited the accompanying balance sheet of International Record
Storage and Retrieval Service, Inc. as of December 31, 1995 and the related
statements of operations, stockholders' deficit, 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 International Record Storage

            INTERNATIONAL RECORD STORAGE AND RETRIEVAL SERVICE, INC.
                          NOTES TO FINANCIAL STATEMENTS

NOTE 1--NATURE OF BUSINESS:

   The Company is engaged principally in the storage of records for customers
in the New Jersey-New York area and providing ancillary services in
conjunction with such records.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   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.

   Revenue Recognition

   Storage and service revenues are recognized in the month the respective
service is provided. Storage material sales are recognized when shipped to
the customer. The Company invoices storage charges to its customers in
advance and these advanced billings are recorded as accounts receivable and
the related revenues are included as deferred income in the accompanying
financial statements.

   Inventories


   Inventories are carried at the lower of cost or market using the first-in
first-out basis and are comprised primarily of cartons.


   Income Taxes

   The Company has elected to be treated as an "S" Corporation under the
applicable sections of the Internal Revenue Code. Under these sections,
corporate income or loss is allocated to the stockholders for inclusion in
their personal income tax returns. Accordingly, there is no provision for
federal income tax in the accompanying financial statements. State income
taxes are recorded in accordance with Statement of Financial Accounting
Standards
No. 109.

   Equipment and Improvements

   Equipment and improvements are stated at cost and depreciated using the
straight-line method with the following useful lives:

   Office Equipment  ....................................     5 years
   Transportation equipment  ............................     5 to 10 years
   Shelving and warehouse improvements  .................     10 to 15 years

   Impairment of Long-Lived Assets

   The Company periodically assesses the recoverability of the carrying
amounts of long-lived assets, including intangible assets. A loss is
recognized when expected undiscounted future cash flows are less than the
carrying amount of the asset. The impairment loss is the difference by which
the carrying amount of the asset exceeds its fair value.

   Deferred Rent

   The Company's lease for its building used in the storage of records has
fixed escalation clauses which require the normalization of rental expense
over the life of the lease, resulting in deferred rent being reflected in the
accompanying balance sheets.

            INTERNATIONAL RECORD STORAGE AND RETRIEVAL SERVICE, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (Continued)

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

   Fair Value of Financial Instruments

   The fair value of the Company's assets and liabilities which qualify as
financial instruments under Statement of Financial Accounting Standards (SFAS)
No. 107, "Disclosures about Fair Value of Financial Instruments", approximates
the carrying amounts presented in the balance sheets.

   Unaudited Financial Statements

   The unaudited financial statements included herein have been prepared in
accordance with generally accepted accounting principles. In the opinion of
management, the unaudited financial statements include all adjustments of a
normal and recurring nature which are necessary for a fair presentation. The
results of operations for the six months ended June 30, 1995 and 1996 are not
necessarily indicative of the results expected for the full year.

NOTE 3--EQUIPMENT AND IMPROVEMENTS:

   Equipment and improvements consist of the following:

                              DECEMBER 31, 1995 
1. Nature of Business 


   DKA Industries, Inc. d/b/a Systems Record Storage (the Company) provides 
record storage and management services in the Orlando, Florida, area. 


2. Summary of Significant Accounting Policies 


   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. 

   Revenue Recognition 

   Storage and service revenues are recognized in the month the respective 
service is provided. Storage material sales are recognized when shipped to 
the customer. Amounts related to future storage for customers where storage 
fees are billed in advance are accounted for as deferred income and 
recognized in the applicable period. 

   Inventories 


   Inventories are carried at the lower of cost or market using the first-in, 
first-out basis, and are comprised primarily of cartons. 


   Goodwill 


   Goodwill is amortized over 40 years. For 1995, amortization was $625. As 
of December 31, 1995, there was $4,375 of accumulated amortization. 


   Income Taxes 


   The Company has elected to be treated as an S corporation under the 
applicable sections of the Internal Revenue Code. Under these sections, 
corporate income or loss is allocated to the stockholders for inclusion in 
their personal income tax returns. Accordingly, there is no provision for 
federal income taxes in the accompanying financial statements. 


   Property and Equipment 


   Equipment and improvements are stated at cost and depreciated or amortized 
using accelerated methods with the following useful lives: 





                                       Years 
                                       ------ 
                                    
Office and computer equipment            5-7 
Transportation equipment                   5 
Warehouse equipment and 
  improvements                          7-10 


   Deferred Rent 


   The Company's lease for its building used in the storage of records has 
uneven rental payments which requires the normalization of rental expense 
over the life of the lease, resulting in deferred rent being reflected in the 
accompanying balance sheet.

                 NOTES TO FINANCIAL STATEMENTS -- (Continued) 


   Fair Value of Financial Instruments 

   The fair value of the Company's assets and liabilities which qualify as 
financial instruments under Statement of Financial Accounting Standards No. 
107, "Disclosures about Fair Value of Financial Instruments," approximates 
the carrying amounts presented in the balance sheet. 


   Unaudited Financial Statements 


   The unaudited financial statements included herein have been prepared 
pursuant to the rules and regulations of the Securities and Exchange 
Commission. In the opinion of management, the unaudited financial statements 
include all adjustments of a normal and recurring nature which are necessary 
for a fair presentation. The results of operations for the six months ended 
June 30, 1996, are not necessarily indicative of the results expected for the 
full year.

To the Board of Directors of 
 Iron Mountain Incorporated: 



We have audited the accompanying balance sheet of Security Archives 
Corporation (a Minnesota corporation) as of December 31, 1995, and the 
related statements of operations and accumulated deficit 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 Security Archives 
Corporation as of December 31, 1995, and the results of its operations and 
its cash flows for the year then ended in conformity with generally accepted

full service records management company providing storage and related 
services for all media. The Company serves numerous legal, banking, 
healthcare, accounting, insurance, entertainment and retail organizations in 
the Los Angeles, California metropolitan area. 



Inventories 



   Inventories are carried at the lower of cost (using the first-in, 
first-out basis) or market and are comprised primarily of cartons. 



Property and Equipment 



   Depreciation and amortization of property and equipment are recorded using 
the straight-line and accelerated methods. Property and equipment consist of 
the following: 





                                                Useful         December 31,

   Minor maintenance costs are expensed as incurred. Major improvements are 
capitalized and depreciated as described above. 



Revenue Recognition 



   Storage and service revenues are recognized in the month the respective 
service is provided. Storage material sales are recognized when shipped to 
the customer. The Company has two customers which accounted for 25% of 
revenues for the year ended December 31, 1995. 



Cash and Cash Equivalents 



   The Company considers all highly liquid investments purchased with a 
maturity of three months or less to be cash equivalents. 



Other Assets 



   Other assets consist of customer acquisition costs. Costs, net of revenues 
received for the initial transfer of records, related to the acquisition of 
accounts are capitalized and amortized for an appropriate period not 
exceeding three years, unless the customer terminates its relationship with 
the Company, at which time the unamortized cost is charged to expense. 
However, in the event of such termination, the Company collects and records 
as income permanent removal fees that generally equal or exceed the amount of 
unamortized customer acquisition costs. 



Financial Instruments 



   Unless otherwise noted, financial instruments are stated at cost, which 
approximates fair value.

                        SECURITY ARCHIVES CORPORATION 
                 NOTES TO FINANCIAL STATEMENTS -- (Continued) 



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. These estimates relate primarily to the realizability of 
accounts receivable and the adequacy of certain accrued expenses. Actual 
results could differ from those estimates. 



Unaudited Financial Information 



   The financial information as of June 30, 1996 and for the six-month 
periods ended June 30, 1996 and 1995 is unaudited and has been prepared 
pursuant to the rules and regulations of the Securities and Exchange 
Commission. In the opinion of management, such information reflects all 
normal recurring adjustments necessary for a fair presentation. Operating 
results for the six months ended June 30, 1996 are not necessarily indicative 
of the results that may be expected for the year ending December 31, 1996. 
Included in service and storage materials sales for the six months ended June 
30, 1996 is $250,000 of fees paid to the Company for removal of cartons for a 
large customer that transferred its business to Iron Mountain Incorporated.

1996. 



4. Income Taxes

which requires the recognition of deferred tax assets and liabilities for the 
expected tax consequences of temporary differences between the tax and 
financial reporting bases of assets and liabilities. 


   The tax effects of temporary differences that give rise to significant 
portions of the deferred tax assets and deferred tax liabilities are 
presented below (in thousands):

   As of December 31, 1995, the Company has NOL carryforwards of $745,106 
which expire in varying amounts through 2009. The primary deferred tax 
liabilities consist of tax over book depreciation. The valuation allowance 
relates to uncertainties surrounding the realization of the NOL 
carryforwards.

revenue in the accompanying balance sheet. The Company has one customer which 
accounted for 13% of revenues for the year ended December 31, 1995.

Income Taxes 



   The Company has elected to be taxed as an S corporation under the

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. These estimates relate primarily to the realizability of 
accounts receivable and the adequacy of certain accrued expenses. Actual 
results could differ from those estimates. 



Concentrations of Credit Risk 



   Credit risk with respect to accounts receivable is generally spread across 
a large number of customers with dispersion across different businesses. As 
of December 31, 1995, one customer accounted for 17% of outstanding accounts 
receivable. 



Unaudited Financial Information 



   The financial information as of June 30, 1996 and for the six-month 
periods ended June 30, 1995 and 1996 is unaudited and has been prepared 
pursuant to the rules and regulations of the Securities and Exchange 
Commission. In the opinion of management, such information reflects all 
normal recurring adjustments necessary for a fair presentation. Operating 
results for the six months ended June 30, 1996 are not necessarily indicative 
of the results that may be expected for the year ending December 31, 1996.

Item 14. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law (the "DGCL") provides, in
effect, that any person made a party to any action by reason of the fact that he
is or was a director, officer, employee or agent of the Company may and, in
certain cases, must be indemnified by the Company against, in the case of a
non-derivative action, judgments, fines, amounts paid in settlement and
reasonable expenses (including attorney's fees) incurred by him as a result of
such action, and in the case of a derivative action, against expenses (including
attorney's fees), if in either type of action he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company. This indemnification does not apply, in a derivative action, to
matters as to which it is adjudged that the director, officer, employee or agent
is liable to the Company, unless upon court order it is determined that, despite
such adjudication of liability, but in view of all the circumstances of the
case, he is fairly and reasonable entitled to indemnity for expenses, and, in a
non-derivative action, to any criminal proceeding in which such person had
reasonable cause to believe his conduct was unlawful.

   Article Sixth of the Company's Amended and Restated Certificate of
Incorporation provides that the Company shall indemnify each person who is or
was an officer or director of the Company to the fullest extent permitted by
Section 145 of the DGCL.

   Article Seventh of the Company's Amended and Restated Certificate of
Incorporation states that no director of the Company shall be liable to the
Company or its stockholders for monetary damages for breach of fiduciary duty as
a director, except to the extent that exculpation from liability is not
permitted under the Delaware General Corporation Law as in effect when such
breach occurred.

   Reference is made to Section 7 of the Underwriting Agreement filed as Exhibit
1 hereto, pursuant to which the underwriters have agreed to indemnify officers
and directors of the Company against certain liabilities.

Item 15. Recent Sales of Unregistered Securities.

   The Company's Amended and Restated Certificate of Incorporation provides for
16,000,000 shares of authorized capital stock, each with par value $.01 per
share, as follows: 13,000,000 shares of authorized Common Stock, 1,000,000
shares of authorized Nonvoting Common Stock and 2,000,000 shares of Preferred
Stock. On February 6, 1996, simultaneously with the consummation of the
Company's Initial Public Offering and without any action on the part of the

Preferred Stock, par value $0.01 per share ("Series A1 Preferred Stock"), Series
A2 Convertible Preferred Stock, par value $0.01 per share, Series A3 Convertible
Preferred Stock, par value $0.01 per share, and Series C Convertible Preferred
Stock, par value $0.01 per share (the "Old Preferred Stock"), was automatically
converted into shares

                                      II-1


of Common Stock (or, in the case of one holder, shares of Common Stock and
500,000 shares of Nonvoting Common Stock). All of the shares of Common Stock and
Nonvoting Common Stock issued as a result of such conversion were issued by the
Company in reliance on the exemptions provided by Sections 3(a)(9) and 4(2) of
the Securities Act. No commission or other remuneration was paid or given by the
Company directly or indirectly for effecting the exchange.

   On January 31, 1994, one shareholder of the Company exchanged 98,000 shares
of Series A1 Preferred Stock for an equal number of shares of Series A2
Preferred Stock. On November 28, 1995, another shareholder of the Company
exchanged 43,500 shares of Series A1 Preferred Stock for an equal number of
shares of Series A3 Preferred Stock. All such shares were issued by the Company
in reliance on the exemptions provided by Sections 3(a)(9) and 4(2) of the
Securities Act. No commission or other remuneration was paid or given by the
Company directly or indirectly for effecting the exchange.

   In 1995, the Company (i) issued options to acquire an aggregate of 162,184
shares of its Class A Common Stock pursuant to its stock option plan to certain
of its officers and employees and (ii) issued to one employee an aggregate of
1,036 shares of Class A Common Stock pursuant to the exercise of stoock options
granted under the Company's stock option plan for an aggregate purchase price of
$200,984. In 1995, the Company also issued options to acquire an aggregate of
65,152 shares of its Common Stock pursuant to its stock option plan to certain
of its officers and employees (which grants were conditioned on the consummation
of the Initial Public Offering). In April 1996, the Company issued options to
acquire an additional 361,452 shares. All securities referred to in this
paragraph were issued by the Company in reliance on the exemption provided by
Section 4(2) of the Securities Act or Rule 701 promulgated thereunder.

(b) Financial Statement Schedules

   The following Financial Statement Schedule is filed herewith:

   Schedule II--Valuation and Qualifying Accounts

Item 17. Undertakings

   Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrants, the
Registrants have been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by a Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, such Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

   The undersigned Registrants hereby undertake that:

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

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

                                      II-6


                                   SIGNATURES

   
   Pursuant to the requirements of the Securities Act of 1933, as amended, Iron
Mountain Incorporated has duly caused this amendment to its Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Boston, Commonwealth of Massachusetts, on September
25, 1996.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
 Iron Mountain Incorporated:

   We have audited, in accordance with generally accepted auditing standards,
the consolidated financial statements of Iron Mountain Incorporated for each of
the three years in the period ended December 31, 1995 and have issued our report
thereon dated February 26, 1996. Our audits were made for the purpose of forming
an opinion on those statements taken as a whole. The accompanying supplemental
schedule is the responsibility of the Company's management and is presented for
purposes of complying with the Securities and Exchange Commission's rules and
regulations under the Securities and Exchange Act of 1934 and is not a required
part of the basic financial statements. The supplemental schedule has been
subjected to the auditing procedures applied in our audits of the basic
financial statements and, in our opinion, is fairly stated, in all material
respects, in relation to the basic financial statements taken as a whole.
