                      % 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
<PAGE>

   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
<PAGE>

           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

<S>                            <C>
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."

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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

   
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

(Footnotes from the preceding page)
   
(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

                                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.

                              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."

30, 1996 has been prepared as if the Transactions had all been completed as of
June 30, 1996 and reflects the following adjustments:

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
<PAGE>

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:

   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
<PAGE>

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
<PAGE>

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
<PAGE>

   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
<PAGE>

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
<PAGE>

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
<PAGE>

   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
<PAGE>

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
<PAGE>

           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
<PAGE>

   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
<PAGE>

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
<PAGE>

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
<PAGE>

           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
<PAGE>

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
<PAGE>

   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]

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
<PAGE>

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.

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
<PAGE>

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.

(2) Potential Realizable Value is based on the assumed growth rates for an

    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
<PAGE>

   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
<PAGE>

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
<PAGE>

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
forth in an Officers' Certificate

                                       66
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

   
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
<PAGE>

   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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

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.

Additional Information

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

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

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

Eurodollar Loans from time to time in effect; (ii) a fronting fee of 1/4 of 1%;
plus (iii) customary issuing fees and expenses.

Company and its subsidiaries to, among other things: (i) declare dividends or

                          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.

Stearns") and Prudential Securities Incorporated (together with DLJ and Bear
Stearns, the "Underwriters"), each of the several Underwriters has severally

                                                              $150,000,000
                                                              ============

   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.

                             VALIDITY OF SECURITIES

   The validity of the securities offered hereby will be passed upon for the
Company by Sullivan & Worcester LLP, Boston, Massachusetts, and for the
Underwriters by Jones, Day, Reavis & Pogue, New York, New York. Jas. Murray
Howe, Secretary of the Company, is of counsel to Sullivan & Worcester LLP and
beneficially owns 3,855 shares of Common Stock.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                     (In thousands except per share data)

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

   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:

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

                    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.

                                      $99,753    $125,240

   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.

            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:

   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.

   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

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

Series C Preferred (voting) .......      $0.01       351,395      351,395

   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
                                        --------   ----------

Series A2 .........................      98,000    1,935,146
Series C ..........................     351,395    4,809,793

   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:

$7,296 at December 31, 1995 to reduce future Federal income taxes, if any,
which begin to expire in 2005.

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:

 Year                                                     Operating
 -----------------------------------------------------   ----------
1996  ................................................    $ 18,278
1997  ................................................      15,571
1998  ................................................      13,585
1999  ................................................      13,332
2000  ................................................      13,537
Thereafter  ..........................................      53,465
                                                            --------
Total minimum lease payments  ........................    $127,768
                                                            ========

   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

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

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

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.

                        (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.

                         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.

              NOTES TO COMBINED FINANCIAL STATEMENTS -- (Continued)

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.

their compensation to the plan on a tax deferred basis. Employee
contributions may be made with a maximum deferral up to 15 percent of
compensation, not to exceed the annual limitations established by the
Treasury.


   The Companies are required to make contributions to the plan, but the
amount of the contribution is determined by the Companies. During the year
ended May 31, 1996, the Companies contributed $12,013 to the plan.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of Iron Mountain Incorporated:

   We have audited the accompanying balance sheet of Data Storage Systems,
Inc. (a California corporation) as of December 31, 1995, and the related
statements of operations, shareholders' 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 Data Storage Systems,
Inc. 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

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

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.


4. PREFERRED STOCK:

Series A, Series B, and Series C Convertible Preferred Stock

   The Convertible Preferred Stock outstanding consists of 1,000,000,
266,666, and 1,083,334 shares of Series A Convertible Preferred Stock
("Series A"), Series B Convertible Preferred Stock ("Series B"), and Series C
Convertible Preferred Stock ("Series C"), respectively.

   The rights and preferences of the Series A, Series B and Series C
Convertible Preferred Stock are as follows:

Dividends

   The holders of the Series C shall be entitled when and if declared by the
Board of Directors, to dividends at a rate of $0.05 per share, per annum,
payable in preference and priority to payment of any dividend to the holders
of Series A, Series B or Common Stock. The holders of the Series A shall be
entitled when and if declared by the Board of Directors, to dividends at a
rate of $0.09 per share, per annum, payable in preference and priority to

holders of the Series B shall be entitled when and if declared by the Board
of Directors, to dividends at a rate of $0.12 per share, per annum, payable
in preference and priority to payment of any dividend to the holders of
Common Stock. After an equal amount per share has been paid on all Common and
Preferred Stock, the holders of Series B shall be entitled to dividends in an
amount per share equal to any further dividend on Common Stock. Dividends are
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
funds are insufficient to permit the payment of the entire preferential
amount, then the entire assets and funds legally available for distribution
shall be distributed ratably among the holders of Series C.

   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
share for each share of Series A held by them. If the remaining assets and
funds are insufficient to permit the payment of the entire preferential
amount, then the entire assets and funds legally available for distribution
shall be distributed ratably among the holders of Series A.

   The holders of the Series B 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 Common Stock, an amount equal to $1.37 per share for each

shareholders, the holders of Common Stock shall be entitled to receive an
amount equal to $0.40 per share for each share of Common Stock held by them.
After the aforementioned distributions to the holders of Preferred and Common
Stock, all remaining assets and funds of the Company legally available for

                           DATA STORAGE SYSTEMS, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (Continued)

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
and Retrieval Service, Inc. 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.

            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.

                  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:

management company, International Management Services, Inc. (IMS). IMS
provides certain administrative services to the Company under agreements
designed to reimburse IMS for the approximate cost of providing such

specific repayment terms.

   The Company incurred charges for management fees to IMS of approximately
$90,000 for the year ended December 31, 1995 and $44,000 and $50,000 for the
six months ended June 30, 1995 (unaudited) and 1996 (unaudited),

                              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:

Warehouse equipment and 
  improvements                          7-10 
</TABLE>

   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.

   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.

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,

significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audit provides a

services for all media. The Company serves numerous legal, banking, 
healthcare, accounting, insurance, entertainment and retail organizations in 
the Los Angeles, California metropolitan area.

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

</TABLE>


   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. 



2. Notes Payable

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.

 Iron Mountain Incorporated: 



We have audited the accompanying balance sheet of Mohawk Business Record 
Storage, Inc. (a Minnesota corporation) as of December 31, 1995, and the 
related statements of operations and retained earnings 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 Mohawk Business Record 
Storage, Inc. 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 -- (Continued) 



Income Taxes 



   The Company has elected to be taxed as an S corporation under the 
applicable Internal Revenue Code sections. The net income of the Company is 
included in the individual income tax returns of the stockholders. 
Accordingly, there is no provision for federal income taxes in the 
accompanying financial statements. 



Financial Instruments 



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



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. 



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
holders thereof, all outstanding shares of the Company's Series A1 Convertible
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

<PAGE>

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.

                    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.

                                 FRIGATE, LTD.

the corporation.

                                     -1-

<PAGE>


      4.1 COMMON STOCK.
          ------------

      4.1.1 General. The voting, dividend and liquidation rights of the holders
of the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock.

      4.1.2 Voting. The holders of shares of Common Stock are entitled to one
vote for each share held at all meetings of stockholders (and written actions in
lieu of meetings). There shall be no cumulative voting.

      4.1.3 Dividends. Dividends may be declared and paid on the Common Stock
from funds lawfully available therefor when and as determined by the Board of
Directors and subject to any preferential dividend rights of any
then-outstanding Preferred Stock.

      4.1.4 Liquidation. Upon the dissolution or liquidation of the corporation,
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive the net assets of the corporation available for distribution to its
stockholders, subject to any preferential rights of any then-outstanding
Preferred Stock.

      4.2 PREFERRED STOCK.
          ---------------

      4.2.1 General. The rights, preferences, powers and privileges and the
restrictions, qualifications and limitations of the Preferred Stock are set
forth below. Authority is hereby expressly granted to the Board of Directors to
issue the Preferred Stock.

      As used herein, the term "Junior Stock" shall mean, with respect to the
Preferred Stock, the Common Stock or any other equity security of the
corporation ranking junior to the Preferred Stock as to dividends or assets.

      4.2.2 No Voting Rights. Except as otherwise required by the laws of the

                                     -2-

<PAGE>


      4.2.3 Dividends. The holders of the then-outstanding Preferred Stock shall
be entitled to receive, when and as declared by the Board, out of any funds
legally available therefor, dividends at the annual rate of $165.00 per share
payable quarterly in cash on the first day of January, April, July and October
of each year. To the extent that dividends are not paid in cash, dividends may,
at the election of the Board of Directors of the corporation, be paid in
additional shares of Preferred Stock in lieu of cash. Dividends on the Preferred
Stock shall be cumulative and shall accrue on each share of Preferred Stock from
the date of issue thereof. Dividends payable on the Preferred Stock for any
period less than a full quarter shall be computed on the basis of a 360-day
year. So long as any shares of the Preferred Stock are outstanding, the
corporation shall not declare, pay or set apart any dividend on any Junior Stock
(other than dividends payable in shares of Common Stock) or declare, make or set
apart any distribution on any Junior Stock unless concurrently therewith all
accrued dividends or distributions on the Preferred Stock, through the date of
such declaration, payment, making or setting apart of any dividend or
distribution on the Junior Stock, are declared, paid, made or set apart, as the
case may be.

      4.2.4 Liquidation. In the event of any liquidation, dissolution or winding
up of the corporation, whether voluntary or involuntary, the holders of the
Preferred Stock (including any shares of Preferred Stock issued as a dividend
upon the Preferred Stock pursuant to Section 4.2.3 hereof) shall be entitled,
before any distribution or payment is made upon any shares of any Junior Stock,
to be paid an amount per share equal to $1,000.00 plus an amount equal to all
unpaid dividends thereon, if any, through the date of such payment to the
holders of the Preferred Stock before any payment shall be made to the

                                     -3-

<PAGE>



holders of the Junior Stock, and the holders of the Preferred Stock shall not be
entitled to any further distribution of assets. If, upon any dissolution,
liquidation or winding up of the corporation, the net assets available for
distribution to the corporation's stockholders shall be insufficient to permit
payment to the holders of the Preferred Stock of the amount distributable as
aforesaid, the entire assets of the corporation to be so distributed shall be
distributed pro rata among the holders of the Preferred Stock. Upon any such
liquidation, dissolution or winding up, after the holders of the Preferred Stock
shall have been paid in full the amount to which they shall be entitled
hereunder, the remaining net assets of the corporation may be distributed to the
holders of the Junior Stock. Written notice of such liquidation, dissolution or
winding up, setting a payment date, the amount of the payment to holders of the
Preferred Stock, and the place where said amount shall be payable shall be given
not less than thirty (30) days prior to the payment date stated therein, to each
holder of record of the Preferred Stock. The liquidation preference provided for
herein with respect to the Preferred Stock shall be equitably adjusted to
reflect any combination or split-up with respect to the Preferred Stock.

      4.2.5 Redemption.
            ----------

      (a) Redemption of Preferred Stock. Shares of the Preferred Stock shall be
subject to redemption, at the option of the corporation exercised by vote of the
Board of Directors, at any time and from time to time, upon notice given as
hereinafter provided, at a price equal to $1,000.00 per share (the "Redemption
Price"), together with all accrued but unpaid dividends thereon. Any amounts
required to be paid pursuant to this Section 4.2.5 shall be paid by delivery of
cash or certified or official bank check.

                                     -4-

<PAGE>



           (b) Redemption Procedure. Not less than sixty (60) days' prior
written notice shall be given by mail, postage prepaid to the holders of record
of the Preferred Stock to be redeemed, addressed to each such holder at his post
office address as shown by the records of the corporation. Said notice shall
specify the manner of payment for the shares of Preferred Stock called for
redemption and the place at which and the date, which date shall not be a legal
holiday in Boston, Massachusetts, on which such shares will be redeemed and
shall specify the shares called for redemption. If such notice of redemption
shall have been duly given and if on or before the redemption date specified in
such notice the funds necessary for such redemption shall have been set aside so
as to be and continue to be available therefor, then, notwithstanding that any
certificate for shares so called for redemption shall not have been surrendered
for cancellation, after the close of business on such redemption date, the
shares so called for redemption shall no longer be deemed outstanding, the
dividends thereon shall cease to accrue, and all rights with respect to shares
so called for redemption, including the rights, if any, to receive notice and to
vote, shall forthwith after the close of business on such redemption date cease
and determine, except only the right of the holders thereof to receive the
amount payable upon redemption thereof. Subject to the provisions hereof, the
Board of Directors shall have authority to prescribe the manner in which the
Preferred Stock shall be redeemed from time to time.

      (c) Redeemed or Otherwise Acquired Shares to be Retired. Any shares of the
Preferred Stock redeemed pursuant to this Section 4.2.5 or otherwise acquired by
the corporation in any manner whatsoever shall be permanently retired and shall
not under any

                                     -5-

<PAGE>



circumstances be reissued; and the corporation may from time to time take such
appropriate corporate action as may be necessary to reduce the authorized
Preferred Stock accordingly.

      (d) Shares to be Redeemed. All shares of Preferred Stock to be redeemed
shall be selected pro rata, and there shall be so redeemed from each registered
holder in whole shares, as nearly as practicable to the nearest share, that
proportion of all of the shares to be redeemed which the number of shares held
of record by such holder bears to the total number of the shares of Preferred
Stock at the time outstanding. 

      (e) All Past Dividends Must Be Paid Prior to Redemption. Except with the
consent of the holders of not less than 66-2/3% of the shares of Preferred Stock
at the time outstanding scheduled to be redeemed pursuant to this Section 4.2.5,
the corporation shall not purchase or redeem shares of Preferred Stock at the
time outstanding unless all dividends on such Preferred Stock for all past
dividend periods shall have been paid or declared and a sum sufficient for the
payment thereof set apart.

            is so interested shall be disclosed or shall have been known to the

            Corporation who is also a director or officer of any such other
            corporation, or who is also interested, may be counted in
            determining the existence of a quorum at any meeting of the Board of
            Directors of the Corporation which shall authorize any such
            contract, act or transaction and may vote thereat to authorize any
            such contract, act or transaction, with like force and effect as if
            he were not such director or officer of such corporation, or not so
            interested.

            valid and as binding as though ratified by every stockholder of the
            Corporation.

      6.    No Director of the Corporation shall be liable to any person on
            account of any action undertaken by him as such director in reliance
            in good faith upon the existence of any fact or circumstance
            reported or certified to the Board of Directors by any officer of
            the Corporation or by any independent auditor, engineer, or
            consultant retained or employed as such by the Board of Directors.

      7.    Meetings of the stockholders may be held without the State of
            Delaware, if the By-laws so provide. The books of the Corporation
            may be kept (subject to any statutory provision) outside the State

its stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of law, (iii) under section 174 of
Title 8 of the Delaware Code relating to the General Corporation Law of the
State of Delaware, or (iv) for any transaction from which the director derived
an improper personal benefit. If the General Corporation Law of the State of
Delaware is hereafter amended to permit further limitation on or elimination of
the personal liability of the Corporation's directors for breach of fiduciary
duty, then a director of the Corporation shall be exempt from such liability for
any such breach to the full extent permitted by the General Corporation Law of
the State of Delaware as so amended from time to time. Any repeal or
modification of the foregoing provisions of this Article, or the adoption of any
provision inconsistent herewith, shall not adversely affect any right or
protection of a director of the Corporation hereunder in respect of any act or
omission of such director occurring prior to such repeal, modification or
adoption of an inconsistent provision.

Without limiting the generality or the effect of the foregoing, the Corporation
may enter into one or more agreements with any person which provide for
indemnification greater or different than that provided in this Article. Neither
the amendment nor repeal of this Article nor the adoption of any provision of
this Certificate of Incorporation inconsistent with this Article shall reduce,
eliminate or adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the effectiveness of such
amendment, repeal or adoption.

                  redeemability, convertibility or otherwise, as the Board of
                  Directors, in its sole discretion, may determine, and to
                  authorize the mortgaging or pledging, as security therefor, of
                  any property of the Corporation, real or personal, including

            In addition to the powers and authorities hereinbefore or by statute
            expressly conferred upon it, the Board of Directors may exercise all
            such powers and do all such acts and things as may be exercised or
            done by the Corporation, subject, nevertheless, to the provisions of
            the laws of the State of Delaware, of the Certificate of
            Incorporation and of the By-laws of the Corporation.

      4.    In the absence of fraud, no contract or other transaction between
            the Corporation and any other corporation, and no act of the
            Corporation, shall in any way be affected or invalidated by the fact
            that any of the Directors of the Corporation are pecuniarily or
            otherwise interested in, or are directors or officer of, such other
            corporation and, in the absence of fraud, any Director may be a
            member, may be a party to, or may be pecuniarily or otherwise
            interested in, any contract or transaction of the Corporation;
            provided, in any case, that the fact that he or such firm is so
            interested shall be disclosed or shall have been known to the Board
            of Directors or a majority thereof; and any Director of the
            Corporation who is also a director or officer of any such other
            corporation, or who is also interested, may be counted in
            determining the existence of a quorum at any meeting of the Board of
            Directors of the Corporation which shall authorize any such
            contract, act or transaction and may vote thereat to authorize any
            such contract, act or transaction, with like force and effect as if
            he were not such director or officer of such corporation, or not so
            interested.

      5.    Any contract, act or transaction of the Corporation or of the
            Directors may be ratified by vote of a majority of the shares having
            voting powers at any meeting of stockholders, or at any special
            meeting called for such purpose, and such ratification shall, so far
            as permitted by law and by this Certificate of Incorporation, be as
            valid and as binding as though ratified by every stockholder of the
            Corporation.

      6.    No Director of the Corporation shall be liable to any person on
            account of any action undertaken by him as such director in reliance
            in good faith upon the existence of any fact or circumstance
            reported or certified to the Board of Directors by any officer of
            the Corporation or by any independent auditor, engineer, or
            consultant retained or employed as such by the Board of Directors.

      7.    Meetings of the stockholders may be held without the State of
            Delaware, if the Bylaws so provide. The books of the Corporation may
            be kept (subject to any statutory provision) outside the State of
            Delaware at such place or places as may be from time to time
            designated by the Board of Directors or in the By-laws of the

                                -3-

            Corporation. Elections of directors need not be by ballot unless the
            By-laws shall otherwise provide.

     EIGHTH: No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; provided, however, that a director of the Corporation shall
be liable for (i) breach of the director's duty of loyalty to the Corporation or
its stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of law, (iii) under section 174 of
Title 8 of the Delaware Code relating to the General Corporation Law of the
State of Delaware, or (iv) for any transaction from which the director derived
an improper personal benefit. If the General Corporation Law of the State of
Delaware is hereafter amended to permit further limitation on or elimination of
the personal liability of the Corporation's directors for breach of fiduciary
duty, then a director of the Corporation shall be exempt from such liability for
any such breach to the full extent permitted by the General Corporation Law of
the State of Delaware as so amended from time to time. Any repeal or
modification of the foregoing provisions of this Article, or the adoption of any
provision inconsistent herewith, shall not adversely affect any right or
protection of a director of the Corporation hereunder in respect of any act or
omission of such director occurring prior to such repeal, modification or
adoption of an inconsistent provision.

      NINTH: The stockholders of the Corporation shall not be personally liable
for the payment of the Corporation's debts.

     TENTH: Each person who is or was or had agreed to become a director or
officer of the Corporation or who is or was serving or who had agreed to serve
at the request of the Board of Directors or an officer of the Corporation as an
employee or agent of the Corporation or as a director, officer, partner, member,
trustee, administrator, employee or agent of another corporation, partnership,
joint venture, limited liability company, trust or other enterprise (including
without limitation any employee benefit plan or any trust associated therewith),
shall be indemnified by the Corporation to the full extent permitted from time
to time by the Delaware General Corporation Law or any other applicable laws as
presently or hereafter in effect. This Article shall inure to the benefit of
each such person and his or her heirs, executors, administrators and estate.
Without limiting the generality or the effect of the foregoing, the Corporation
may enter into one or more agreements with any person which provide for
indemnification greater or different than that provided in this Article. Neither
the amendment nor repeal of this Article nor the adoption of any provision of
this Certificate of Incorporation inconsistent with this Article shall reduce,
eliminate or adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the effectiveness of such
amendment, repeal or adoption.

      ELEVENTH: From time to time any of the provisions of this Certificate of
Incorporation may be amended, altered or repealed, and other provisions
authorized by the laws of the State of Delaware at the time in force may be
added or inserted in the manner and at the time

                                -4-

prescribed by said laws, and all rights at any time conferred upon the
stockholders of the Corporation by this Certificate of Incorporation are granted

                                     BY-LAWS



                                ARTICLE I OFFICES
                               -------------------

     SECTION 1. Registered Office. The registered office of the Corporation
shall be located in Wilmington, County of New Castle, State of Delaware, and the
name of the resident agent in charge thereof shall be Corporation Service
Company.

     SECTION 2. Other Offices. The Corporation may also have offices at such
other places, within or without the State of Delaware, as the Board of Directors
may from time to time appoint or the business of the Corporation may require.

                                 ARTICLE II SEAL
                                -----------------

     The seal of the Corporation shall, subject to alteration by the Board of
Directors, consist of a flat-faced circular die with the word "Delaware",
together with the name of the Corporation and the year of incorporation, cut or
engraved thereon.

                       ARTICLE III MEETING OF STOCKHOLDERS
                      -------------------------------------

      SECTION 1. Place of Meeting. Meetings of the stockholders shall be held
either within or without the State of Delaware at such place as the Board of
Directors may fix from time to time.

      SECTION 2. Annual Meetings. The annual meeting of stockholders shall be
held for the election of directors on such date and at such time as the Board of
Directors may fix from time to time. Any other proper business may be transacted
at the annual meeting.

     SECTION 3. Special Meetings. Special meetings of the stockholders for any
purpose or purposes may be called by the Chairman of the Board of Directors, if
there be one, the President or by the directors (either by written instrument
signed by a majority or by resolution adopted by a vote of the majority), and
special meetings shall be called by the President or the Secretary whenever
stockholders owning at least a majority of the capital stock issued, outstanding
and entitled to vote so

By-laws of Iron Mountain Records Managment of Maryland, Inc.

Page 2

request in writing.  Such request of stockholders shall state the
purpose or purposes of the proposed meeting.

     SECTION 4. Notice. Written or printed notice of every meeting of
stockholders, annual or special, stating the hour, date and place thereof, and
the purpose or purposes in general terms for which the meeting is called shall,
not less than ten (10) days, or such longer period as shall be provided by law,
the Certificate of Incorporation, these By-Laws, or otherwise, and not more than
sixty (60) days before such meeting, be served upon or mailed to each
stockholder entitled to vote thereat, at the address of such stockholder as it
appears upon the stock records of the Corporation or, if such stockholder shall
have filed with the Secretary of the Corporation a written request that notices
be mailed to some other address, then to the address designated in such request.

     Notice of the hour, date, place and purpose of any meeting of stockholders
may be dispensed with if every stockholder entitled to vote thereat shall attend
either in person or by proxy and shall not, at the beginning of the meeting,
object to the holding of such meeting because the meeting has not been lawfully
called or convened, or if every absent stockholder entitled to such notice shall
in writing, filed with the records of the meeting, either before or after the
holding thereof, waive such notice.

     SECTION 5. Quorum and Adjournments. Except as otherwise provided by law or
by the Certificate of Incorporation, the presence in person or by proxy at any
meeting of stockholders of the holders of a majority of the shares of the
capital stock of the Corporation issued and outstanding and entitled to vote
thereat, shall be requisite and shall constitute a quorum. If two or more
classes of stock are entitled to vote as separate classes upon any question,
then, in the case of each such class, a quorum for the consideration of such
question shall, except as otherwise provided by law or by the Certificate of
Incorporation, consist of *** of all stock of that class issued, outstanding and
entitled to vote. If a majority of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote thereat or, where a
larger quorum is required, such quorum, shall not be represented at any meeting
of the stockholders regularly called, the holders of *** of the shares present
or represented by proxy and entitled to vote thereat shall have power to adjourn
the meeting to another time, or to another time and place, without notice other
than announcement of adjournment at the meeting, and there may be successive
adjournments for like cause and in like manner until the requisite amount of
shares entitled to vote at such meeting shall be represented; provided, however,
that if the adjournment is for more than thirty (30) days, notice of the hour,
date and place of the adjourned meeting shall be given to each stockholder
entitled to vote thereat. Subject to the requirements of law and the Certificate
of Incorporation, on


<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.
A Delaware Corporation
Page 3

any issue on which two or more classes of stock are entitled to vote separately,
no adjournment shall be taken with respect to any class for which a quorum is
present unless the Chairman of the meeting otherwise directs. At any meeting
held to consider matters which were subject to adjournment for want of a quorum
at which the requisite amount of shares entitled to vote thereat shall be
represented, any business may be transated which might have been transacted at
the meeting as originally noticed.

     SECTION 6. Votes; Proxies. Except as otherwise provided in the Certificate
of Incorporation, at each meeting of stockholders, every stockholder of record
at the closing of the transfer books, if closed, or on the date set by the Board
of Directors for the determination of stockholders entitled to vote at such
meeting, shall have one vote for each share of stock entitled to vote which is
registered in such stockholder's name on the books of the Corporation, and, in
the election of directors, may vote cumulatively to the extent, if any, and in
the manner authorized in the Certificate of Incorporation.

     At each such meeting every stockholder entitled to vote shall be entitled
to do so in person, or by proxy appointed by an instrument in writing or as
otherwise permitted by law subscribed by such stockholder and bearing a date not
more than three (3) years prior to the meeting in question, unless said
instrument provides for a longer period during which it is to remain in force. A
duly executed proxy shall be irrevocable if it states that it is irrevocable and
if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power. A proxy may be made irrevocable regardless of
whether the interest with which it is coupled is an interest in the stock itself
or any interest in the Corporation generally. A stockholder may revoke any proxy
which is not irrevocable by attending the meeting and voting in person or by
filing with the Secretary of the Corporation an instrument in writing or as
otherwise permitted by law revoking the proxy or another duly executed proxy
bearing a later date.

     Voting at meetings of stockholders need not be by written ballot and,
except as otherwise provided by law, need not be conducted by inspectors of
election unless so determined by the Chairman of the meeting or by the holders
of shares of stock having a majority of the votes which could be cast by the
holders of all outstanding shares of stock entitled to vote thereon which are
present in person or represented by proxy at such meeting. If it is required or
determined that inspectors of election be appointed, the Chairman shall appoint
two inspectors of election, who shall first take and subscribe an oath or
affirmation faithfully to execute the duties of inspectors at such meeting with
strict impartiality and according to the best of their ability. The inspectors
so appointed shall take charge of the polls and, after the balloting, shall make
a certificate of the

By-laws of Iron Mountain Records Managment of Maryland, Inc.

Page 4

result of the vote taken.  No director or candidate for the
office of director shall be appointed as such inspector.

     At any meeting at which a quorum is present, a plurality of the votes
properly cast for election to fill any vacancy on the Board of Directors shall
be sufficient to elect a candidate to fill such vacancy, and a majority of the
votes properly cast upon any other question shall decide the question, except in
any case where a larger vote is required by law, the Certificate of
Incorporation, these By-Laws, or otherwise.

     SECTION 7. Organization. The Chairman of the Board, if there be one, or in
his or her absence the Vice Chairman, or in the absence of a Vice Chairman, the
President, or in the absence of the President, a Vice President, shall call
meetings of the stockholders to order and shall act as chairman thereof. The
Secretary of the Corporation, if present, shall act as secretary of all meetings
of stockholders, and, in his or her absence, the presiding officer may appoint a
secretary.

     SECTION 8. Consent of Stockholders in Lieu of Meeting. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
by the Delaware General Corporation Law to be taken at any annual or special
meeting of the stockholders of the Corporation, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in Delaware, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

     Every written consent shall bear the date of signature of each stockholder
who signs the consent and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty (60) days of the
earliest dated consent delivered in the manner required by this section to the
Corporation, written consents signed by a sufficient number of stockholders to
take action are delivered to the corporation by delivery to its registered
office in Delaware, its principal place of business, or an officer or agent of
the Corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the Corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.

     Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. In the event that the action which is consented
to is such as would have required the filing of a certificate under any section
of the Delaware General Corporation Law other than Section 228 thereof, if such
action had been voted on by stockholders at a meeting thereof, the certificate
filed under such other section shall state, in lieu of any statement required by
such section concerning any vote of stockholders, that written consent has been
given in accordance with Section 228 of the Delaware General Corporation Law,
and that written notice has been given as provided in such Section 228.

                              ARTICLE IV DIRECTORS
                              ---------------------

     SECTION 1. Number. The business and affairs of the Corporation shall be
conducted and managed by a Board of Directors consisting of not less than one
director, none of whom needs to be a stockholder. The number of directors for
each year shall be fixed at each annual meeting of stockholders, but if the
number is not so fixed, the number shall remain as it stood immediately prior to
such meeting.

     At each annual meeting of stockholders, the stockholders shall elect
directors. Each director so elected shall hold office, subject to the provisions
of law, the Certificate of Incorporation, these By-Laws, or otherwise, until the
next annual meeting of stockholders or until his or her successor is elected and
qualified.

     At any time during any year, except as otherwise provided by law, the
Certificate of Incorporation, these By-Laws, or otherwise, the number of
directors may be increased or reduced, in each case by vote of a majority of the
stock issued and outstanding and present in person or represented by proxy and
entitled to vote for the election of directors or a majority of the directors in
office at the time of such increase or decrease, regardless of whether such
majority constitutes a quorum.

     SECTION 2. Term of Office. Each director shall hold office until the next
annual meeting of stockholders and until his or her successor is duly elected
and qualified or until his or her earlier death or resignation, subject to the
right of the stockholders at any time to remove any director or directors as
provided in Section 4 of this Article.

     SECTION 3. Vacancies. If any vacancy shall occur among the directors, or if
the number of directors shall at any time be increased, the directors then in
office, although less than a quorum, by a majority vote may fill the vacancies
or newly-



<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.

Page 6

created directorships, or any such vacancies or newly-created directorships may
be filled by the stockholders at any meeting.

     SECTION 4. Removal by Stockholders. Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the holders of record of the
capital stock of the Corporation entitled to vote for the election of directors
may, by a majority vote, remove any director or directors, with or without
cause, and, in their discretion, elect a new director or directors in place
thereof.

     SECTION 5. Meetings. Meetings of the Board of Directors shall be held at
such place, within or without the State of Delaware, as may from time to time be
fixed by resolution of the Board of Directors or by the Chairman of the Board,
if there be one, or by the President, and as may be specified in the notice or
waiver of notice of any meeting. Meetings may be held at any time upon the call
of the Chairman of the Board, if there be one, or the President or any two (2)
of the directors in office by oral, telegraphic, telex, telecopy or other form
of electronic transmission, or written notice, duly served or sent or mailed to
each director not less than twenty-four (24) hours before such meeting, except
that, if mailed, not less than *** (***) hours before such meeting.

     Meetings may be held at any time and place without notice if all the
directors are present and do not object to the holding of such meeting for lack
of proper notice or if those not present shall, in writing or by telegram,
telex, telecopy or other form of electronic transmission, waive notice thereof.
A regular meeting of the Board may be held without notice immediately following
the annual meeting of stockholders at the place where such meeting is held.
Regular meetings of the Board may also be held without notice at such time and
place as shall from time to time be determined by resolution of the Board.
Except as otherwise provided by law, the Certificate of Incorporation or
otherwise, neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors or any committee thereof
need be specified in any written waiver of notice.

     Members of the Board of Directors or any committee thereof may participate
in a meeting of such Board or committee by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other and participation in a meeting pursuant to the
foregoing provisions shall constitute presence in person at the meeting.

     SECTION 6.        Votes.  Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the vote of the


<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.
A Delaware Corporation
Page 7

majority of the directors present at a meeting at which a quorum is present
shall be the act of the Board of Directors.

     SECTION 7. Quorum and Adjournment. Except as otherwise provided by law, the
Certificate of Incorporation or otherwise, a majority of the directors shall
constitute a quorum for the transaction of business. If at any meeting of the
Board there shall be less than a quorum present, a majority of those present may
adjourn the meeting from time to time without notice other than announcement of
the adjournment at the meeting, and at such adjourned meeting at which a quorum
is present any business may be transacted which might have been transacted at
the meeting as originally noticed.

     SECTION 8. Compensation. Directors shall receive compensation for their
services, as such, and for service on any Committee of the Board of Directors,
as fixed by resolution of the Board of Directors and for expenses of attendance
at each regular or special meeting of the Board or any Committee thereof.
Nothing in this Section shall be construed to preclude a director from serving
the Corporation in any other capacity and receiving compensation therefor.

     SECTION 9. Action By Consent of Directors. Any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee. Such consent shall be
treated as a vote adopted at a meeting for all purposes. Such consents may be
executed in one or more counterparts and not every Director or committee member
need sign the same counterpart.

                        ARTICLE V COMMITTEES OF DIRECTORS
                       -----------------------------------

     SECTION 1. Executive Committee. The Board of Directors may, by resolution
passed by a majority of the whole Board, appoint an Executive Committee of one
(1) or more members, to serve during the pleasure of the Board, to consist of
such directors as the Board may from time to time designate. The Board of
Directors shall designate the Chairman of the Executive Committee.

     a.    Procedure. The Executive Committee shall, by a vote of a majority of
           its members, fix its own times and places of meeting, determine the
           number of its members constituting a quorum for the transaction of
           business, and prescribe its own rules of procedure, no change in
           which shall be made save by a majority vote of its members.

     b.    Responsibilities.  During the intervals between the
           ----------------
           meetings of the Board of Directors, except as otherwise
           provided by the Board of Directors in establishing such
           Committee or otherwise, the Executive Committee shall
           possess and may exercise all the powers of the Board in
           the management and direction of the business and affairs
           of the Corporation; provided, however, that the
           Executive Committee shall not, except to the extent the
           Certificate of Incorporation or the resolution providing
           for the issuance of shares of stock adopted by the Board
           of Directors as provided in Section 151(a) of the
           Delaware General Business Corporation Law, have the
           power:

           (1)  to amend or authorize the amendment of the
           Certificate of Incorporation or these By-Laws;

           (2)  to authorize the issuance of stock;

           (3)  to authorize the payment of any dividend;

           (4) to adopt an agreement of merger or consolidation of the
           Corporation or to recommend to the stockholders the sale, lease or
           exchange of all or substantially all the property and business of the
           Corporation;

           (5)  to recommend to the stockholders a dissolution, or
           a revocation of a dissolution, of the Corporation; or

           (6) to adopt a certificate of ownership and merger pursuant to
           Section 253 of the Delaware Business Corporation Law.

     c.    Reports. The Executive Committee shall keep regular minutes of its
           proceedings, and all action by the Executive Committee shall be
           reported promptly to the Board of Directors. Such action shall be
           subject to review, amendment and repeal by the Board, provided that
           no rights of third parties shall be adversely affected by such
           review, amendment or repeal.

     d.    Appointment of Additional Members. In the absence or disqualification
           of any member of the Executive Committee, the member or members
           thereof present at any meeting and not disqualified from voting,
           whether or not constituting a quorum, may unanimously appoint another
           member of the Board of Directors to act at the meeting in place of
           any such absent or disqualified member.

      SECTION 2. Audit Committee. The Board of Directors may, by resolution
passed by a majority of the whole Board, appoint an Audit Committee of *** (***)
or more members to serve during the


<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.

Page 9

pleasure of the Board.  The Board of Directors shall designate
the Chairman of the Audit Committee.

     a.    Procedure. The Audit Committee, by a vote of a majority of its
           members, shall fix its own times and places of meeting, shall
           determine the number of its members constituting a quorum for the
           transaction of business, and shall prescribe its own rules of
           procedure, no change in which shall be made save by a majority vote
           of its members.

     b.    Responsibilities.  The Audit Committee shall review the
           annual financial statements of the Corporation prior to
           their submission to the Board of Directors, shall
           consult with the Corporation's independent auditors, and
           may examine and consider such other matters in relation
           to the internal and external audit of the Corporation's
           accounts and in relation to the financial affairs of the
           Corporation and its accounts, including the selection

           Such action shall be subject to review, amendment and repeal by the
           Board, provided that no rights of third parties shall be adversely
           affected by such review, amendment or repeal.

     d.    Appointment of Additional Members. In the absence or disqualification
           of any member of the Audit Committee, the member or members thereof
           present at any meeting and not disqualified from voting, whether or

           time, be reported to the Board of Directors as it shall
           direct.  Such action shall be subject to review,
           amendment and repeal by the Board, provided that no

     SECTION 1. Form and Execution of Certificates. The interest of each

certificates for shares of stock in such form as the Board of Directors may from

if any, the President, an Executive Vice President or a Vice President and by

of the Corporation, and may be countersigned and registered in such manner as
the Board of Directors may by resolution prescribe, and shall bear the corporate

Secretary or Assistant Secretary may be facsimiles, engraved or printed. In case
any officer or officers, who shall have signed, or whose facsimile signature or
signatures shall have been used on, any such certificate or certificates, shall
cease to be such officer or officers, whether because of death, resignation or
otherwise, before such certificate or certificates shall have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the person or persons who signed such


<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.
A Delaware Corporation
Page 14

certificate or certificates or whose facsimile signature or signatures shall
have been used thereon had not ceased to be such officer or officers.

     In case the corporate seal which has been affixed to, impressed on, or
reproduced in any such certificate or certificates shall cease to be the seal of
the Corporation before such certificate or certificates have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the seal affixed thereto, impressed
thereon or reproduced therein had not ceased to be the seal of the Corporation.

     Every certificate for shares of stock which are subject to any restriction
on transfer pursuant to law, the Certificate of Incorporation, these By-Laws, or
any agreement to which the Corporation is a party, shall have the restriction
noted conspicuously on the certificate, and shall also set forth, on the face or
back, either the full text of the restriction or a statement of the existence of
such restriction and (except if such restriction is imposed by law) a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

     Every certificate issued when the Corporation is authorized to issue more
than one class or series of stock shall set forth on its face or back either the
full text of the preferences, voting powers, qualifications, and special and
relative rights of the shares of each class and series authorized to be issued,

such proof or guaranty of the authenticity of the signature as the Corporation
or its agents may reasonably require. The Corporation shall be entitled to treat
the holder of record of any share or shares of stock as the holder in fact
thereof and accordingly shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person
whether or not it shall have express or other notice thereof, save as expressly
provided by law or by the Certificate of Incorporation. It shall be the duty of

preceding the date of any meeting of stockholders or the date for the payment of
any dividend or the date for the allotment of rights or the date when any
issuance, change, conversion or exchange of capital stock shall go into effect,
during which time no transfer of stock on the books of the Corporation may be
made.

     SECTION 4. Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
directors and which record date: (a) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than sixty (60) nor less than ten (10)
days before the date of such meeting; (b) in the case of determination of
stockholders entitled to express consent to corporate action in writing without
a meeting, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than ten (10) days from the date upon
which the resolution fixing the record date is adopted by the Board of
Directors; and (c) in the case of any other action, shall not be more than sixty
(60) days prior to such other action. If no record date is fixed: (a) the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or, if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held; (b) the record
date for determining stockholders entitled to express consent to corporate
action in writing without a meeting when no prior action of the Board of
Directors is required by law, shall be the first date on which a signed written
consent setting forth the action take or proposed to be taken is delivered to
the Corporation in accordance with applicable law, or, if prior action by the
Board of Directors is required by law, shall be at the close of business on the
day on which the Board of Directors adopts the resolution taking such prior
action; and (c) the record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto. A determination of
stockholders of

By-laws of Iron Mountain Records Managment of Maryland, Inc.

record entitled to notice of or to vote at a meeting of stockholders shall apply
to any adjournment of the meeting; provided, however, that the Board of
Directors may fix a new record date for the adjourned meeting.

      SECTION 5. Lost or Destroyed Certificates. In case of the loss or
destruction of any certificate of stock, a new certificate may be issued under
the following conditions:

     a.    The owner of said certificate shall file with the
           Secretary or any Assistant Secretary of the Corporation
           an affidavit giving the facts in relation to the
           ownership, and in relation to the loss or destruction of
           said certificate, stating its number and the number of
           shares represented thereby; such affidavit shall be in
           such form and contain such statements as shall satisfy
           the President, any Executive Vice President, Vice
           President, the Secretary, any Assistant Secretary, the
           Treasurer or any Assistant Treasurer, that said
           certificate has been accidentally destroyed or lost, and
           that a new certificate ought to be issued in lieu
           thereof.  Upon being so satisfied, any such officer may
           require such owner to furnish the Corporation a bond in
           such penal sum and in such form as he or she may deem
           advisable, and with a surety or sureties approved by him
           or her, to indemnify and save harmless the Corporation
           from any claim, loss, damage or liability which may be
           occasioned by the issuance of a new certificate in lieu
           thereof.  Upon such bond being so filed, if so required,
           a new certificate for the same number of shares shall be
           issued to the owner of the certificate so lost or
           destroyed; and the transfer agent and registrar, if any,
           of stock shall countersign and register such new
           certificate upon receipt of a written order signed by
           any such officer, and thereupon the Corporation will
           save harmless said transfer agent and registrar in the
           premises.  In case of the surrender of the original
           certificate, in lieu of which a new certificate has been
           issued, or the surrender of such new certificate, for
           cancellation, the bond of indemnity given as a condition
           of the issue of such new certificate may be surrendered;
           or

     b.    The Board of Directors of the Corporation may by
           resolution authorize and direct any transfer agent or
           registrar of stock of the Corporation to issue and
           register respectively from time to time without further
           action or approval by or on behalf of the Corporation
           new certificates of stock to replace certificates
           reported lost, stolen or destroyed upon receipt of an
           affidavit of loss and bond of indemnity in form and
           amount and with surety satisfactory to such transfer

           threatened to be made a party or is otherwise involved
           in any threatened, pending or completed action, suit or
           proceeding, whether civil, criminal, administrative or
           investigative (other than an action by or in the right
           of the Corporation) by reason of the fact that he, or a
           person for whom he or she is the legal representative,
           is or was a director, officer, employee or agent of the
           Corporation, or is or was serving at the request of the
           Corporation as a director, officer, partner, member,

           fees), judgments, fines, and amounts paid in settlement
           actually and reasonably incurred by him or her in

           any action, suit or proceeding by judgment, order,
           settlement, conviction, or upon a plea of nolo
           contendere or its equivalent, shall not, of itself,
           create a presumption that the person did not act in good
           faith and in a manner which he or she reasonably
           believed to be in or not opposed to the best interest of
           the Corporation, and, with respect to any criminal

           action or suit by or in the right of the Corporation to
           procure a judgment in its favor by reason of the fact
           that he or she is or was a director, trustee, partner,
           officer, employee or agent of the Corporation, or is or
           was serving at the request of the Corporation as a
           director, officer, partner, member, trustee, employee or
           agent of another corporation, partnership, joint
           venture, limited liability company, trust or other
           enterprise or non-profit entity against expenses
           (including attorneys' fees) actually and reasonably
           incurred by him or her in connection with the defense or
           settlement of such action or suit if he or she acted in
           good faith and in a manner he or she reasonably believed
           to be in or not opposed to the best interests of the
           Corporation; except that no indemnification shall be
           made in respect of any claim, issue or matter as to
           which such person shall have been adjudged to be liable
           for negligence or misconduct in the performance of his
           or her duty to the Corporation unless and only to the
           extent that the Court of Chancery of the State of
           Delaware or the court in which such action or suit was
           brought shall determine upon application that despite
           the adjudication of liability but in view of all the
           circumstances of the case, such person is fairly and
           reasonably entitled to indemnity for such expenses which
           the Court of Chancery of the State of Delaware or such
           other court shall deem proper.

     c.    To the extent that any person referred to in paragraphs
           a. or b. above has been successful on the merits or
           otherwise in defense of any action, suit or proceeding
           referred to therein, or in defense of any claim, issue
           or matter therein, he or she shall be indemnified
           against expenses (including attorneys' fees) actually
           and reasonably incurred by him or her in connection
           therewith.

      SECTION 2. Authorization. Any indemnification under Section 1 of this
Article (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, partner, member, trustee, employee or agent is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Section 1 of this Article. Such determination shall be made: a. by the
Board of Directors by a majority vote of a quorum consisting of directors who
were not

By-laws of Iron Mountain Records Managment of Maryland, Inc.
A Delaware Corporation
Page 21

parties to such action, suit or proceeding, or b. if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in written opinion, or c. by the
stockholders.

     SECTION 3. Expense Advance. Expenses (including attorneys' fees) incurred
by an officer or director of the Corporation in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in the manner provided in
Section 2 of this Article upon receipt of an undertaking by or on behalf of such
officer or director to repay such amount, unless it shall ultimately be
determined that such person is entitled to be indemnified by the Corporation as
authorized in this Article. Such expenses (including attorneys' fees) incurred
by other employees or agents of the Corporation may be so paid upon such terms
and conditions, if any, as the Board of Directors deems appropriate.

     SECTION 4. Nonexclusivity. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other Sections of this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in an official capacity and as to action in another capacity
while holding such office, and shall continue as to a person who has ceased to
be a director, officer, partner, member, trustee, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

     SECTION 5. Insurance. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, partner, member, trustee, employee or agent
of another corporation, partnership, joint venture, limited liability company,
trust or other enterprise or non-profit entity against any liability asserted
against and incurred by him or her in any such capacity, or arising out of his
or her status as such, whether or not the Corporation would have the power to
indemnify such person against such liability under the provisions of this
Article or Section 145 of Title 8 of the Delaware Code relating to the General
Corporation Law of the State of Delaware.

      SECTION 6. "The Corporation". For the purposes of this Article, references
to "the Corporation" shall include the resulting corporation and, to the extent
that the Board of Directors of the resulting corporation so decides, all
constituent corporations (including any constituent of a


<PAGE>


By-laws of Iron Mountain Records Managment of Maryland, Inc.

Page 22

constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers and employees or agents so that any person who is or was a
director, officer, employee or agent of such a constituent corporation or is or
was serving at the request of such constituent corporation as director, officer,
partner, member, trustee, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise or non-profit entity shall stand in the
same position under the provisions of this Article with respect to the resulting
or surviving corporation if its separate existence had continued.

     SECTION 7. Other Indemnification. The Corporation's obligation, if any, to
indemnify any person who was or is serving at its request as a director,
trustee, partner, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise or non-profit entity shall
be reduced by any amount such person may collect as indemnification from such
other corporation, partnership, joint venture, trust or other enterprise or
non-profit entity or from insurance.

     SECTION 8. Other Definitions. For purposes of this Article, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, trustee, officer, employee or agent of
the Corporation which imposes duties on, or involves services by, such director,
trustee, officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries; and a person who acted in good faith and in
a manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article.

     SECTION 9. Continuation of Indemnification. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall,
unless otherwise provided when authorized or ratified, continue as to a person
who has ceased to be a director, trustee, partner, officer, employee or agent
and shall inure to the benefit of the heirs, executors and administrators of
such a person.

     SECTION 10. Amendment or Repeal. Neither the amendment nor repeal of this
Article nor the adoption of any provision of these By-Laws inconsistent with
this Article shall reduce, eliminate or adversely affect any right or protection
hereunder of any person in respect of any act or omission occurring prior to the
effectiveness of such amendment, repeal or adoption.

                                ARTICLE I OFFICES
                               -------------------

     SECTION 1. Registered Office. The registered office of the Corporation
shall be located in Wilmington, County of New Castle, State of Delaware, and the
name of the resident agent in charge thereof shall be Corporation Service
Company.

     SECTION 2. Other Offices. The Corporation may also have offices at such
other places, within or without the State of Delaware, as the Board of Directors
may from time to time appoint or the business of the Corporation may require.

                                 ARTICLE II SEAL
                                -----------------

     The seal of the Corporation shall, subject to alteration by the Board of
Directors, consist of a flat-faced circular die with the word "Delaware",
together with the name of the Corporation and the year of incorporation, cut or
engraved thereon.

                       ARTICLE III MEETING OF STOCKHOLDERS
                      -------------------------------------

      SECTION 1. Place of Meeting. Meetings of the stockholders shall be held
either within or without the State of Delaware at such place as the Board of
Directors may fix from time to time.

      SECTION 2. Annual Meetings. The annual meeting of stockholders shall be
held for the election of directors on such date and at such time as the Board of
Directors may fix from time to time. Any other proper business may be transacted
at the annual meeting.

     SECTION 3. Special Meetings. Special meetings of the stockholders for any
purpose or purposes may be called by the Chairman of the Board of Directors, if
there be one, the President or by the directors (either by written instrument
signed by a majority or by resolution adopted by a vote of the majority), and
special meetings shall be called by the President or the Secretary whenever
stockholders owning at least a majority of the capital stock issued, outstanding
and entitled to vote so

request in writing.  Such request of stockholders shall state the
purpose or purposes of the proposed meeting.

     SECTION 4. Notice. Written or printed notice of every meeting of
stockholders, annual or special, stating the hour, date and place thereof, and
the purpose or purposes in general terms for which the meeting is called shall,
not less than ten (10) days, or such longer period as shall be provided by law,
the Certificate of Incorporation, these By-Laws, or otherwise, and not more than
sixty (60) days before such meeting, be served upon or mailed to each
stockholder entitled to vote thereat, at the address of such stockholder as it
appears upon the stock records of the Corporation or, if such stockholder shall
have filed with the Secretary of the Corporation a written request that notices
be mailed to some other address, then to the address designated in such request.

     Notice of the hour, date, place and purpose of any meeting of stockholders
may be dispensed with if every stockholder entitled to vote thereat shall attend
either in person or by proxy and shall not, at the beginning of the meeting,
object to the holding of such meeting because the meeting has not been lawfully
called or convened, or if every absent stockholder entitled to such notice shall
in writing, filed with the records of the meeting, either before or after the
holding thereof, waive such notice.

     SECTION 5. Quorum and Adjournments. Except as otherwise provided by law or
by the Certificate of Incorporation, the presence in person or by proxy at any
meeting of stockholders of the holders of a majority of the shares of the
capital stock of the Corporation issued and outstanding and entitled to vote
thereat, shall be requisite and shall constitute a quorum. If two or more
classes of stock are entitled to vote as separate classes upon any question,
then, in the case of each such class, a quorum for the consideration of such
question shall, except as otherwise provided by law or by the Certificate of
Incorporation, consist of *** of all stock of that class issued, outstanding and
entitled to vote. If a majority of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote thereat or, where a
larger quorum is required, such quorum, shall not be represented at any meeting
of the stockholders regularly called, the holders of *** of the shares present
or represented by proxy and entitled to vote thereat shall have power to adjourn
the meeting to another time, or to another time and place, without notice other
than announcement of adjournment at the meeting, and there may be successive
adjournments for like cause and in like manner until the requisite amount of
shares entitled to vote at such meeting shall be represented; provided, however,
that if the adjournment is for more than thirty (30) days, notice of the hour,
date and place of the adjourned meeting shall be given to each stockholder
entitled to vote thereat. Subject to the requirements of law and the Certificate
of Incorporation, on


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.
A Delaware Corporation
Page 3

any issue on which two or more classes of stock are entitled to vote separately,
no adjournment shall be taken with respect to any class for which a quorum is
present unless the Chairman of the meeting otherwise directs. At any meeting
held to consider matters which were subject to adjournment for want of a quorum
at which the requisite amount of shares entitled to vote thereat shall be
represented, any business may be transated which might have been transacted at
the meeting as originally noticed.

     SECTION 6. Votes; Proxies. Except as otherwise provided in the Certificate
of Incorporation, at each meeting of stockholders, every stockholder of record
at the closing of the transfer books, if closed, or on the date set by the Board
of Directors for the determination of stockholders entitled to vote at such
meeting, shall have one vote for each share of stock entitled to vote which is
registered in such stockholder's name on the books of the Corporation, and, in
the election of directors, may vote cumulatively to the extent, if any, and in
the manner authorized in the Certificate of Incorporation.

     At each such meeting every stockholder entitled to vote shall be entitled
to do so in person, or by proxy appointed by an instrument in writing or as
otherwise permitted by law subscribed by such stockholder and bearing a date not
more than three (3) years prior to the meeting in question, unless said
instrument provides for a longer period during which it is to remain in force. A
duly executed proxy shall be irrevocable if it states that it is irrevocable and
if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power. A proxy may be made irrevocable regardless of
whether the interest with which it is coupled is an interest in the stock itself
or any interest in the Corporation generally. A stockholder may revoke any proxy
which is not irrevocable by attending the meeting and voting in person or by
filing with the Secretary of the Corporation an instrument in writing or as
otherwise permitted by law revoking the proxy or another duly executed proxy
bearing a later date.

     Voting at meetings of stockholders need not be by written ballot and,
except as otherwise provided by law, need not be conducted by inspectors of
election unless so determined by the Chairman of the meeting or by the holders
of shares of stock having a majority of the votes which could be cast by the
holders of all outstanding shares of stock entitled to vote thereon which are
present in person or represented by proxy at such meeting. If it is required or
determined that inspectors of election be appointed, the Chairman shall appoint
two inspectors of election, who shall first take and subscribe an oath or
affirmation faithfully to execute the duties of inspectors at such meeting with
strict impartiality and according to the best of their ability. The inspectors
so appointed shall take charge of the polls and, after the balloting, shall make
a certificate of the


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.

Page 4

result of the vote taken.  No director or candidate for the
office of director shall be appointed as such inspector.

     At any meeting at which a quorum is present, a plurality of the votes
properly cast for election to fill any vacancy on the Board of Directors shall
be sufficient to elect a candidate to fill such vacancy, and a majority of the
votes properly cast upon any other question shall decide the question, except in
any case where a larger vote is required by law, the Certificate of
Incorporation, these By-Laws, or otherwise.

     SECTION 7. Organization. The Chairman of the Board, if there be one, or in
his or her absence the Vice Chairman, or in the absence of a Vice Chairman, the
President, or in the absence of the President, a Vice President, shall call
meetings of the stockholders to order and shall act as chairman thereof. The
Secretary of the Corporation, if present, shall act as secretary of all meetings
of stockholders, and, in his or her absence, the presiding officer may appoint a
secretary.

     SECTION 8. Consent of Stockholders in Lieu of Meeting. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
by the Delaware General Corporation Law to be taken at any annual or special
meeting of the stockholders of the Corporation, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in Delaware, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

     Every written consent shall bear the date of signature of each stockholder
who signs the consent and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty (60) days of the
earliest dated consent delivered in the manner required by this section to the
Corporation, written consents signed by a sufficient number of stockholders to
take action are delivered to the corporation by delivery to its registered
office in Delaware, its principal place of business, or an officer or agent of
the Corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the Corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.

     Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. In the event that the action which is consented
to is such as would have required the filing of a certificate under any section
of the Delaware General Corporation Law other than Section 228 thereof, if such
action had been voted on by stockholders at a meeting thereof, the certificate
filed under such other section shall state, in lieu of any statement required by
such section concerning any vote of stockholders, that written consent has been
given in accordance with Section 228 of the Delaware General Corporation Law,
and that written notice has been given as provided in such Section 228.

                              ARTICLE IV DIRECTORS
                              ---------------------

     SECTION 1. Number. The business and affairs of the Corporation shall be
conducted and managed by a Board of Directors consisting of not less than one
director, none of whom needs to be a stockholder. The number of directors for
each year shall be fixed at each annual meeting of stockholders, but if the
number is not so fixed, the number shall remain as it stood immediately prior to
such meeting.

     At each annual meeting of stockholders, the stockholders shall elect
directors. Each director so elected shall hold office, subject to the provisions
of law, the Certificate of Incorporation, these By-Laws, or otherwise, until the
next annual meeting of stockholders or until his or her successor is elected and
qualified.

     At any time during any year, except as otherwise provided by law, the
Certificate of Incorporation, these By-Laws, or otherwise, the number of
directors may be increased or reduced, in each case by vote of a majority of the
stock issued and outstanding and present in person or represented by proxy and
entitled to vote for the election of directors or a majority of the directors in
office at the time of such increase or decrease, regardless of whether such
majority constitutes a quorum.

     SECTION 2. Term of Office. Each director shall hold office until the next
annual meeting of stockholders and until his or her successor is duly elected
and qualified or until his or her earlier death or resignation, subject to the
right of the stockholders at any time to remove any director or directors as
provided in Section 4 of this Article.

     SECTION 3. Vacancies. If any vacancy shall occur among the directors, or if
the number of directors shall at any time be increased, the directors then in
office, although less than a quorum, by a majority vote may fill the vacancies
or newly-

<PAGE>

By-laws of Iron Mountain Records Managment of Ohio, Inc.

Page 6



created directorships, or any such vacancies or newly-created directorships may 
be filled by the stockholders at any meeting.

     SECTION 4. Removal by Stockholders. Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the holders of record of the
capital stock of the Corporation entitled to vote for the election of directors
may, by a majority vote, remove any director or directors, with or without
cause, and, in their discretion, elect a new director or directors in place
thereof.

     SECTION 5. Meetings. Meetings of the Board of Directors shall be held at
such place, within or without the State of Delaware, as may from time to time be
fixed by resolution of the Board of Directors or by the Chairman of the Board,
if there be one, or by the President, and as may be specified in the notice or
waiver of notice of any meeting. Meetings may be held at any time upon the call
of the Chairman of the Board, if there be one, or the President or any two (2)
of the directors in office by oral, telegraphic, telex, telecopy or other form
of electronic transmission, or written notice, duly served or sent or mailed to
each director not less than twenty-four (24) hours before such meeting, except
that, if mailed, not less than *** (***) hours before such meeting.

     Meetings may be held at any time and place without notice if all the
directors are present and do not object to the holding of such meeting for lack
of proper notice or if those not present shall, in writing or by telegram,
telex, telecopy or other form of electronic transmission, waive notice thereof.
A regular meeting of the Board may be held without notice immediately following
the annual meeting of stockholders at the place where such meeting is held.
Regular meetings of the Board may also be held without notice at such time and
place as shall from time to time be determined by resolution of the Board.
Except as otherwise provided by law, the Certificate of Incorporation or
otherwise, neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors or any committee thereof
need be specified in any written waiver of notice.

     Members of the Board of Directors or any committee thereof may participate
in a meeting of such Board or committee by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other and participation in a meeting pursuant to the
foregoing provisions shall constitute presence in person at the meeting.

      SECTION 6. Votes. Except as otherwise provided by law, the Certificate of
Incorporation or otherwise, the vote of the


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.
A Delaware Corporation
Page 7

majority of the directors present at a meeting at which a quorum is present
shall be the act of the Board of Directors.

     SECTION 7. Quorum and Adjournment. Except as otherwise provided by law, the
Certificate of Incorporation or otherwise, a majority of the directors shall
constitute a quorum for the transaction of business. If at any meeting of the
Board there shall be less than a quorum present, a majority of those present may
adjourn the meeting from time to time without notice other than announcement of
the adjournment at the meeting, and at such adjourned meeting at which a quorum
is present any business may be transacted which might have been transacted at

<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.
A Delaware Corporation
Page 14

certificate or certificates or whose facsimile signature or signatures shall
have been used thereon had not ceased to be such officer or officers.

     In case the corporate seal which has been affixed to, impressed on, or
reproduced in any such certificate or certificates shall cease to be the seal of
the Corporation before such certificate or certificates have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the seal affixed thereto, impressed
thereon or reproduced therein had not ceased to be the seal of the Corporation.

     Every certificate for shares of stock which are subject to any restriction
on transfer pursuant to law, the Certificate of Incorporation, these By-Laws, or
any agreement to which the Corporation is a party, shall have the restriction
noted conspicuously on the certificate, and shall also set forth, on the face or
back, either the full text of the restriction or a statement of the existence of
such restriction and (except if such restriction is imposed by law) a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

     Every certificate issued when the Corporation is authorized to issue more
than one class or series of stock shall set forth on its face or back either the
full text of the preferences, voting powers, qualifications, and special and
relative rights of the shares of each class and series authorized to be issued,

such proof or guaranty of the authenticity of the signature as the Corporation
or its agents may reasonably require. The Corporation shall be entitled to treat
the holder of record of any share or shares of stock as the holder in fact
thereof and accordingly shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person
whether or not it shall have express or other notice thereof, save as expressly
provided by law or by the Certificate of Incorporation. It shall be the duty of

any dividend or the date for the allotment of rights or the date when any
issuance, change, conversion or exchange of capital stock shall go into effect,
during which time no transfer of stock on the books of the Corporation may be
made.

     SECTION 4. Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
directors and which record date: (a) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than sixty (60) nor less than ten (10)
days before the date of such meeting; (b) in the case of determination of
stockholders entitled to express consent to corporate action in writing without
a meeting, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than ten (10) days from the date upon
which the resolution fixing the record date is adopted by the Board of
Directors; and (c) in the case of any other action, shall not be more than sixty
(60) days prior to such other action. If no record date is fixed: (a) the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or, if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held; (b) the record
date for determining stockholders entitled to express consent to corporate
action in writing without a meeting when no prior action of the Board of
Directors is required by law, shall be the first date on which a signed written
consent setting forth the action take or proposed to be taken is delivered to
the Corporation in accordance with applicable law, or, if prior action by the
Board of Directors is required by law, shall be at the close of business on the
day on which the Board of Directors adopts the resolution taking such prior
action; and (c) the record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto. A determination of
stockholders of


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.

Page 16

record entitled to notice of or to vote at a meeting of stockholders shall apply
to any adjournment of the meeting; provided, however, that the Board of
Directors may fix a new record date for the adjourned meeting.

     SECTION 5. Lost or Destroyed Certificates. In case of the loss or
destruction of any certificate of stock, a new certificate may be issued under
the following conditions:

     a.    The owner of said certificate shall file with the
           Secretary or any Assistant Secretary of the Corporation
           an affidavit giving the facts in relation to the
           ownership, and in relation to the loss or destruction of
           said certificate, stating its number and the number of
           shares represented thereby; such affidavit shall be in
           such form and contain such statements as shall satisfy
           the President, any Executive Vice President, Vice
           President, the Secretary, any Assistant Secretary, the
           Treasurer or any Assistant Treasurer, that said
           certificate has been accidentally destroyed or lost, and
           that a new certificate ought to be issued in lieu
           thereof.  Upon being so satisfied, any such officer may
           require such owner to furnish the Corporation a bond in
           such penal sum and in such form as he or she may deem
           advisable, and with a surety or sureties approved by him
           or her, to indemnify and save harmless the Corporation
           from any claim, loss, damage or liability which may be
           occasioned by the issuance of a new certificate in lieu
           thereof.  Upon such bond being so filed, if so required,
           a new certificate for the same number of shares shall be
           issued to the owner of the certificate so lost or
           destroyed; and the transfer agent and registrar, if any,
           of stock shall countersign and register such new
           certificate upon receipt of a written order signed by
           any such officer, and thereupon the Corporation will
           save harmless said transfer agent and registrar in the
           premises.  In case of the surrender of the original
           certificate, in lieu of which a new certificate has been
           issued, or the surrender of such new certificate, for
           cancellation, the bond of indemnity given as a condition
           of the issue of such new certificate may be surrendered;
           or

     b.    The Board of Directors of the Corporation may by
           resolution authorize and direct any transfer agent or
           registrar of stock of the Corporation to issue and
           register respectively from time to time without further
           action or approval by or on behalf of the Corporation
           new certificates of stock to replace certificates
           reported lost, stolen or destroyed upon receipt of an
           affidavit of loss and bond of indemnity in form and
           amount and with surety satisfactory to such transfer

                           ARTICLE XII INDEMNIFICATION
                          -----------------------------

     SECTION 1. Indemnification.

     a.    Action By Third Party.  The Corporation shall indemnify
           and hold harmless, to the fullest extent permitted by
           applicable law as it presently exists or may hereafter
           be amended, any person who was or is a party or is
           threatened to be made a party or is otherwise involved
           in any threatened, pending or completed action, suit or
           proceeding, whether civil, criminal, administrative or
           investigative (other than an action by or in the right
           of the Corporation) by reason of the fact that he, or a
           person for whom he or she is the legal representative,
           is or was a director, officer, employee or agent of the
           Corporation, or is or was serving at the request of the
           Corporation as a director, officer, partner, member,
           trustee, employee or agent of another corporation,
           partnership, joint venture, limited liability company,
           trust or other enterprise or non-profit entity against
           all liability, losses, expenses (including attorneys'
           fees), judgments, fines, and amounts paid in settlement
           actually and reasonably incurred by him or her in
           connection with such action, suit or proceeding if he or
           she acted in good faith and in a manner he or she
           reasonably believed to be in or not opposed to the best
           interest of the Corporation, and, with respect to any
           criminal action or proceeding, had no reasonable cause
           to believe his conduct was unlawful.  The termination of
           any action, suit or proceeding by judgment, order,
           settlement, conviction, or upon a plea of nolo
           contendere or its equivalent, shall not, of itself,
           create a presumption that the person did not act in good
           faith and in a manner which he or she reasonably
           believed to be in or not opposed to the best interest of
           the Corporation, and, with respect to any criminal


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.
A Delaware Corporation
Page 20

           action or proceeding, had reasonable cause to believe
           that his or her conduct was unlawful.

      b.   Action By Corporation.  The Corporation shall indemnify
           any person who was or is a party or is threatened to be
           made a party to any threatened, pending or completed
           action or suit by or in the right of the Corporation to
           procure a judgment in its favor by reason of the fact
           that he or she is or was a director, trustee, partner,
           officer, employee or agent of the Corporation, or is or
           was serving at the request of the Corporation as a
           director, officer, partner, member, trustee, employee or
           agent of another corporation, partnership, joint
           venture, limited liability company, trust or other
           enterprise or non-profit entity against expenses
           (including attorneys' fees) actually and reasonably
           incurred by him or her in connection with the defense or
           settlement of such action or suit if he or she acted in
           good faith and in a manner he or she reasonably believed
           to be in or not opposed to the best interests of the
           Corporation; except that no indemnification shall be
           made in respect of any claim, issue or matter as to
           which such person shall have been adjudged to be liable
           for negligence or misconduct in the performance of his
           or her duty to the Corporation unless and only to the
           extent that the Court of Chancery of the State of
           Delaware or the court in which such action or suit was
           brought shall determine upon application that despite
           the adjudication of liability but in view of all the
           circumstances of the case, such person is fairly and
           reasonably entitled to indemnity for such expenses which
           the Court of Chancery of the State of Delaware or such
           other court shall deem proper.

     c.    To the extent that any person referred to in paragraphs
           a. or b. above has been successful on the merits or
           otherwise in defense of any action, suit or proceeding
           referred to therein, or in defense of any claim, issue
           or matter therein, he or she shall be indemnified
           against expenses (including attorneys' fees) actually
           and reasonably incurred by him or her in connection
           therewith.

     SECTION 2. Authorization. Any indemnification under Section 1 of this
Article (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, partner, member, trustee, employee or agent is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Section 1 of this Article. Such determination shall be made: a. by the
Board of Directors by a majority vote of a quorum consisting of directors who
were not


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.
A Delaware Corporation
Page 21

parties to such action, suit or proceeding, or b. if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in written opinion, or c. by the
stockholders.

     SECTION 3. Expense Advance. Expenses (including attorneys' fees) incurred
by an officer or director of the Corporation in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in the manner provided in
Section 2 of this Article upon receipt of an undertaking by or on behalf of such
officer or director to repay such amount, unless it shall ultimately be
determined that such person is entitled to be indemnified by the Corporation as
authorized in this Article. Such expenses (including attorneys' fees) incurred
by other employees or agents of the Corporation may be so paid upon such terms
and conditions, if any, as the Board of Directors deems appropriate.

     SECTION 4. Nonexclusivity. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other Sections of this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in an official capacity and as to action in another capacity
while holding such office, and shall continue as to a person who has ceased to
be a director, officer, partner, member, trustee, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

     SECTION 5. Insurance. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, partner, member, trustee, employee or agent
of another corporation, partnership, joint venture, limited liability company,
trust or other enterprise or non-profit entity against any liability asserted
against and incurred by him or her in any such capacity, or arising out of his
or her status as such, whether or not the Corporation would have the power to
indemnify such person against such liability under the provisions of this
Article or Section 145 of Title 8 of the Delaware Code relating to the General
Corporation Law of the State of Delaware.

     SECTION 6. "The Corporation". For the purposes of this Article, references
to "the Corporation" shall include the resulting corporation and, to the extent
that the Board of Directors of the resulting corporation so decides, all
constituent corporations (including any constituent of a


<PAGE>


By-laws of Iron Mountain Records Managment of Ohio, Inc.

Page 22

constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers and employees or agents so that any person who is or was a
director, officer, employee or agent of such a constituent corporation or is or
was serving at the request of such constituent corporation as director, officer,
partner, member, trustee, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise or non-profit entity shall stand in the
same position under the provisions of this Article with respect to the resulting
or surviving corporation if its separate existence had continued.

     SECTION 7. Other Indemnification. The Corporation's obligation, if any, to
indemnify any person who was or is serving at its request as a director,
trustee, partner, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise or non-profit entity shall
be reduced by any amount such person may collect as indemnification from such
other corporation, partnership, joint venture, trust or other enterprise or
non-profit entity or from insurance.

     SECTION 8. Other Definitions. For purposes of this Article, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, trustee, officer, employee or agent of
the Corporation which imposes duties on, or involves services by, such director,
trustee, officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries; and a person who acted in good faith and in
a manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article.

     SECTION 9. Continuation of Indemnification. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall,
unless otherwise provided when authorized or ratified, continue as to a person
who has ceased to be a director, trustee, partner, officer, employee or agent
and shall inure to the benefit of the heirs, executors and administrators of
such a person.

     SECTION 10. Amendment or Repeal. Neither the amendment nor repeal of this
Article nor the adoption of any provision of these By-Laws inconsistent with
this Article shall reduce, eliminate or adversely affect any right or protection
hereunder of any person in respect of any act or omission occurring prior to the
effectiveness of such amendment, repeal or adoption.

                                ARTICLE I OFFICES
                               -------------------

     SECTION 1. Registered Office. The registered office of the Corporation
shall be located in Wilmington, County of New Castle, State of Delaware, and the
name of the resident agent in charge thereof shall be Corporation Service
Company.

     SECTION 2. Other Offices. The Corporation may also have offices at such
other places, within or without the State of Delaware, as the Board of Directors
may from time to time appoint or the business of the Corporation may require.

                                 ARTICLE II SEAL
                                -----------------

     The seal of the Corporation shall, subject to alteration by the Board of
Directors, consist of a flat-faced circular die with the word "Delaware",
together with the name of the Corporation and the year of incorporation, cut or
engraved thereon.

                       ARTICLE III MEETING OF STOCKHOLDERS
                      -------------------------------------

     SECTION 1.        Place of Meeting.  Meetings of the
stockholders shall be held either within or without the State of
Delaware at such place as the Board of Directors may fix from
time to time.

     SECTION 2.        Annual Meetings.  The annual meeting of
stockholders shall be held for the election of directors on such
date and at such time as the Board of Directors may fix from time
to time.  Any other proper business may be transacted at the
annual meeting.

     SECTION 3. Special Meetings. Special meetings of the stockholders for any
purpose or purposes may be called by the Chairman of the Board of Directors, if
there be one, the President or by the directors (either by written instrument
signed by a majority or by resolution adopted by a vote of the majority), and
special meetings shall be called by the President or the Secretary whenever
stockholders owning at least a majority of the capital stock issued, outstanding
and entitled to vote so


<PAGE>


By-laws of Data Storage Systems, Inc.
A Delaware Corporation
Page 2

request in writing.  Such request of stockholders shall state the
purpose or purposes of the proposed meeting.

     SECTION 4. Notice. Written or printed notice of every meeting of
stockholders, annual or special, stating the hour, date and place thereof, and
the purpose or purposes in general terms for which the meeting is called shall,
not less than ten (10) days, or such longer period as shall be provided by law,
the Certificate of Incorporation, these By-Laws, or otherwise, and not more than
sixty (60) days before such meeting, be served upon or mailed to each
stockholder entitled to vote thereat, at the address of such stockholder as it
appears upon the stock records of the Corporation or, if such stockholder shall
have filed with the Secretary of the Corporation a written request that notices
be mailed to some other address, then to the address designated in such request.

     Notice of the hour, date, place and purpose of any meeting of stockholders
may be dispensed with if every stockholder entitled to vote thereat shall attend
either in person or by proxy and shall not, at the beginning of the meeting,
object to the holding of such meeting because the meeting has not been lawfully
called or convened, or if every absent stockholder entitled to such notice shall
in writing, filed with the records of the meeting, either before or after the
holding thereof, waive such notice.

     SECTION 5. Quorum and Adjournments. Except as otherwise provided by law or
by the Certificate of Incorporation, the presence in person or by proxy at any
meeting of stockholders of the holders of a majority of the shares of the
capital stock of the Corporation issued and outstanding and entitled to vote
thereat, shall be requisite and shall constitute a quorum. If two or more
classes of stock are entitled to vote as separate classes upon any question,
then, in the case of each such class, a quorum for the consideration of such
question shall, except as otherwise provided by law or by the Certificate of
Incorporation, consist of *** of all stock of that class issued, outstanding and
entitled to vote. If a majority of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote thereat or, where a
larger quorum is required, such quorum, shall not be represented at any meeting
of the stockholders regularly called, the holders of *** of the shares present
or represented by proxy and entitled to vote thereat shall have power to adjourn
the meeting to another time, or to another time and place, without notice other
than announcement of adjournment at the meeting, and there may be successive
adjournments for like cause and in like manner until the requisite amount of
shares entitled to vote at such meeting shall be represented; provided, however,
that if the adjournment is for more than thirty (30) days, notice of the hour,
date and place of the adjourned meeting shall be given to each stockholder
entitled to vote thereat. Subject to the requirements of law and the Certificate
of Incorporation, on


<PAGE>


By-laws of Data Storage Systems, Inc.
A Delaware Corporation
Page 3

any issue on which two or more classes of stock are entitled to vote separately,
no adjournment shall be taken with respect to any class for which a quorum is
present unless the Chairman of the meeting otherwise directs. At any meeting
held to consider matters which were subject to adjournment for want of a quorum
at which the requisite amount of shares entitled to vote thereat shall be
represented, any business may be transated which might have been transacted at
the meeting as originally noticed.

     SECTION 6. Votes; Proxies. Except as otherwise provided in the Certificate
of Incorporation, at each meeting of stockholders, every stockholder of record
at the closing of the transfer books, if closed, or on the date set by the Board
of Directors for the determination of stockholders entitled to vote at such
meeting, shall have one vote for each share of stock entitled to vote which is
registered in such stockholder's name on the books of the Corporation, and, in
the election of directors, may vote cumulatively to the extent, if any, and in
the manner authorized in the Certificate of Incorporation.

     At each such meeting every stockholder entitled to vote shall be entitled
to do so in person, or by proxy appointed by an instrument in writing or as
otherwise permitted by law subscribed by such stockholder and bearing a date not
more than three (3) years prior to the meeting in question, unless said
instrument provides for a longer period during which it is to remain in force. A
duly executed proxy shall be irrevocable if it states that it is irrevocable and
if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power. A proxy may be made irrevocable regardless of
whether the interest with which it is coupled is an interest in the stock itself
or any interest in the Corporation generally. A stockholder may revoke any proxy
which is not irrevocable by attending the meeting and voting in person or by
filing with the Secretary of the Corporation an instrument in writing or as
otherwise permitted by law revoking the proxy or another duly executed proxy
bearing a later date.

     Voting at meetings of stockholders need not be by written ballot and,
except as otherwise provided by law, need not be conducted by inspectors of
election unless so determined by the Chairman of the meeting or by the holders
of shares of stock having a majority of the votes which could be cast by the
holders of all outstanding shares of stock entitled to vote thereon which are
present in person or represented by proxy at such meeting. If it is required or
determined that inspectors of election be appointed, the Chairman shall appoint
two inspectors of election, who shall first take and subscribe an oath or
affirmation faithfully to execute the duties of inspectors at such meeting with
strict impartiality and according to the best of their ability. The inspectors
so appointed shall take charge of the polls and, after the balloting, shall make
a certificate of the


<PAGE>


By-laws of Data Storage Systems, Inc.

Page 4

result of the vote taken. No director or candidate for the office of director
shall be appointed as such inspector.

     At any meeting at which a quorum is present, a plurality of the votes
properly cast for election to fill any vacancy on the Board of Directors shall
be sufficient to elect a candidate to fill such vacancy, and a majority of the
votes properly cast upon any other question shall decide the question, except in
any case where a larger vote is required by law, the Certificate of
Incorporation, these By-Laws, or otherwise.

     SECTION 7. Organization. The Chairman of the Board, if there be one, or in
his or her absence the Vice Chairman, or in the absence of a Vice Chairman, the
President, or in the absence of the President, a Vice President, shall call
meetings of the stockholders to order and shall act as chairman thereof. The
Secretary of the Corporation, if present, shall act as secretary of all meetings
of stockholders, and, in his or her absence, the presiding officer may appoint a
secretary.

     SECTION 8. Consent of Stockholders in Lieu of Meeting. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
by the Delaware General Corporation Law to be taken at any annual or special
meeting of the stockholders of the Corporation, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary

                              ---------------------

     SECTION 1. Number. The business and affairs of the Corporation shall be
conducted and managed by a Board of Directors consisting of not less than one
director, none of whom needs to be a stockholder. The number of directors for
each year shall be fixed at each annual meeting of stockholders, but if the
number is not so fixed, the number shall remain as it stood immediately prior to
such meeting.

     At each annual meeting of stockholders, the stockholders shall elect
directors. Each director so elected shall hold office, subject to the provisions
of law, the Certificate of Incorporation, these By-Laws, or otherwise, until the
next annual meeting of stockholders or until his or her successor is elected and
qualified.

     At any time during any year, except as otherwise provided by law, the
Certificate of Incorporation, these By-Laws, or otherwise, the number of
directors may be increased or reduced, in each case by vote of a majority of the
stock issued and outstanding and present in person or represented by proxy and
entitled to vote for the election of directors or a majority of the directors in
office at the time of such increase or decrease, regardless of whether such
majority constitutes a quorum.

     SECTION 2. Term of Office. Each director shall hold office until the next
annual meeting of stockholders and until his or her successor is duly elected
and qualified or until his or her earlier death or resignation, subject to the
right of the stockholders at any time to remove any director or directors as
provided in Section 4 of this Article.

     SECTION 3. Vacancies. If any vacancy shall occur among the directors, or if
the number of directors shall at any time be increased, the directors then in
office, although less than a quorum, by a majority vote may fill the vacancies
or newly-

created directorships, or any such vacancies or newly-created directorships may
be filled by the stockholders at any meeting.

     SECTION 4. Removal by Stockholders. Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the holders of record of the
capital stock of the Corporation entitled to vote for the election of directors
may, by a majority vote, remove any director or directors, with or without
cause, and, in their discretion, elect a new director or directors in place
thereof.

     SECTION 5. Meetings. Meetings of the Board of Directors shall be held at
such place, within or without the State of Delaware, as may from time to time be
fixed by resolution of the Board of Directors or by the Chairman of the Board,
if there be one, or by the President, and as may be specified in the notice or
waiver of notice of any meeting. Meetings may be held at any time upon the call
of the Chairman of the Board, if there be one, or the President or any two (2)
of the directors in office by oral, telegraphic, telex, telecopy or other form
of electronic transmission, or written notice, duly served or sent or mailed to
each director not less than twenty-four (24) hours before such meeting, except
that, if mailed, not less than *** (***) hours before such meeting.

     Meetings may be held at any time and place without notice if all the
directors are present and do not object to the holding of such meeting for lack
of proper notice or if those not present shall, in writing or by telegram,
telex, telecopy or other form of electronic transmission, waive notice thereof.
A regular meeting of the Board may be held without notice immediately following
the annual meeting of stockholders at the place where such meeting is held.
Regular meetings of the Board may also be held without notice at such time and
place as shall from time to time be determined by resolution of the Board.
Except as otherwise provided by law, the Certificate of Incorporation or
otherwise, neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors or any committee thereof
need be specified in any written waiver of notice.

     Members of the Board of Directors or any committee thereof may participate
in a meeting of such Board or committee by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other and participation in a meeting pursuant to the
foregoing provisions shall constitute presence in person at the meeting.

     SECTION 6.        Votes.  Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the vote of the


<PAGE>


By-laws of Data Storage Systems, Inc.

majority of the directors present at a meeting at which a quorum is present
shall be the act of the Board of Directors.

     SECTION 7. Quorum and Adjournment. Except as otherwise provided by law, the
Certificate of Incorporation or otherwise, a majority of the directors shall
constitute a quorum for the transaction of business. If at any meeting of the
Board there shall be less than a quorum present, a majority of those present may
adjourn the meeting from time to time without notice other than announcement of
the adjournment at the meeting, and at such adjourned meeting at which a quorum
is present any business may be transacted which might have been transacted at
the meeting as originally noticed.

     SECTION 8. Compensation. Directors shall receive compensation for their
services, as such, and for service on any Committee of the Board of Directors,
as fixed by resolution of the Board of Directors and for expenses of attendance
at each regular or special meeting of the Board or any Committee thereof.
Nothing in this Section shall be construed to preclude a director from serving
the Corporation in any other capacity and receiving compensation therefor.

     SECTION 9. Action By Consent of Directors. Any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee. Such consent shall be
treated as a vote adopted at a meeting for all purposes. Such consents may be
executed in one or more counterparts and not every Director or committee member
need sign the same counterpart.

           direct.  Such action shall be subject to review,
           amendment and repeal by the Board, provided that no

Secretary or Assistant Secretary may be facsimiles, engraved or printed. In case
any officer or officers, who shall have signed, or whose facsimile signature or
signatures shall have been used on, any such certificate or certificates, shall
cease to be such officer or officers, whether because of death, resignation or

<PAGE>


By-laws of Data Storage Systems, Inc.
A Delaware Corporation
Page 14

certificate or certificates or whose facsimile signature or signatures shall
have been used thereon had not ceased to be such officer or officers.

     In case the corporate seal which has been affixed to, impressed on, or
reproduced in any such certificate or certificates shall cease to be the seal of
the Corporation before such certificate or certificates have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the seal affixed thereto, impressed
thereon or reproduced therein had not ceased to be the seal of the Corporation.

     Every certificate for shares of stock which are subject to any restriction
on transfer pursuant to law, the Certificate of Incorporation, these By-Laws, or
any agreement to which the Corporation is a party, shall have the restriction
noted conspicuously on the certificate, and shall also set forth, on the face or
back, either the full text of the restriction or a statement of the existence of
such restriction and (except if such restriction is imposed by law) a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

     Every certificate issued when the Corporation is authorized to issue more
than one class or series of stock shall set forth on its face or back either the
full text of the preferences, voting powers, qualifications, and special and
relative rights of the shares of each class and series authorized to be issued,

such proof or guaranty of the authenticity of the signature as the Corporation
or its agents may reasonably require. The Corporation shall be entitled to treat
the holder of record of any share or shares of stock as the holder in fact
thereof and accordingly shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person
whether or not it shall have express or other notice thereof, save as expressly
provided by law or by the Certificate of Incorporation. It shall be the duty of
each stockholder to notify the Corporation of his or her post office address.

preceding the date of any meeting of stockholders or the date for the payment of
any dividend or the date for the allotment of rights or the date when any
issuance, change, conversion or exchange of capital stock shall go into effect,
during which time no transfer of stock on the books of the Corporation may be

     SECTION 4. Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
directors and which record date: (a) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than sixty (60) nor less than ten (10)
days before the date of such meeting; (b) in the case of determination of
stockholders entitled to express consent to corporate action in writing without
a meeting, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than ten (10) days from the date upon
which the resolution fixing the record date is adopted by the Board of
Directors; and (c) in the case of any other action, shall not be more than sixty
(60) days prior to such other action. If no record date is fixed: (a) the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or, if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held; (b) the record
date for determining stockholders entitled to express consent to corporate

     SECTION 5. Lost or Destroyed Certificates. In case of the loss or
destruction of any certificate of stock, a new certificate may be issued under
the following conditions:

     a.    The owner of said certificate shall file with the
           Secretary or any Assistant Secretary of the Corporation
           an affidavit giving the facts in relation to the
           ownership, and in relation to the loss or destruction of
           said certificate, stating its number and the number of
           shares represented thereby; such affidavit shall be in
           such form and contain such statements as shall satisfy
           the President, any Executive Vice President, Vice
           President, the Secretary, any Assistant Secretary, the
           Treasurer or any Assistant Treasurer, that said
           certificate has been accidentally destroyed or lost, and
           that a new certificate ought to be issued in lieu
           thereof.  Upon being so satisfied, any such officer may
           require such owner to furnish the Corporation a bond in
           such penal sum and in such form as he or she may deem
           advisable, and with a surety or sureties approved by him
           or her, to indemnify and save harmless the Corporation
           from any claim, loss, damage or liability which may be
           occasioned by the issuance of a new certificate in lieu
           thereof.  Upon such bond being so filed, if so required,
           a new certificate for the same number of shares shall be
           issued to the owner of the certificate so lost or
           destroyed; and the transfer agent and registrar, if any,
           of stock shall countersign and register such new
           certificate upon receipt of a written order signed by
           any such officer, and thereupon the Corporation will
           save harmless said transfer agent and registrar in the
           premises.  In case of the surrender of the original
           certificate, in lieu of which a new certificate has been
           issued, or the surrender of such new certificate, for
           cancellation, the bond of indemnity given as a condition
           of the issue of such new certificate may be surrendered;
           or

     b.    The Board of Directors of the Corporation may by
           resolution authorize and direct any transfer agent or
           registrar of stock of the Corporation to issue and
           register respectively from time to time without further
           action or approval by or on behalf of the Corporation
           new certificates of stock to replace certificates
           reported lost, stolen or destroyed upon receipt of an
           affidavit of loss and bond of indemnity in form and
           amount and with surety satisfactory to such transfer

                           ARTICLE XII INDEMNIFICATION
                          -----------------------------

     SECTION 1.        Indemnification.

     a.    Action By Third Party.  The Corporation shall indemnify
           and hold harmless, to the fullest extent permitted by
           applicable law as it presently exists or may hereafter
           be amended, any person who was or is a party or is
           threatened to be made a party or is otherwise involved
           in any threatened, pending or completed action, suit or
           proceeding, whether civil, criminal, administrative or
           investigative (other than an action by or in the right
           of the Corporation) by reason of the fact that he, or a
           person for whom he or she is the legal representative,
           is or was a director, officer, employee or agent of the
           Corporation, or is or was serving at the request of the
           Corporation as a director, officer, partner, member,
           trustee, employee or agent of another corporation,
           partnership, joint venture, limited liability company,
           trust or other enterprise or non-profit entity against
           all liability, losses, expenses (including attorneys'
           fees), judgments, fines, and amounts paid in settlement
           actually and reasonably incurred by him or her in
           connection with such action, suit or proceeding if he or
           she acted in good faith and in a manner he or she
           reasonably believed to be in or not opposed to the best
           interest of the Corporation, and, with respect to any
           criminal action or proceeding, had no reasonable cause
           to believe his conduct was unlawful.  The termination of
           any action, suit or proceeding by judgment, order,
           settlement, conviction, or upon a plea of nolo
           contendere or its equivalent, shall not, of itself,
           create a presumption that the person did not act in good
           faith and in a manner which he or she reasonably
           believed to be in or not opposed to the best interest of
           the Corporation, and, with respect to any criminal

Page 20

           action or proceeding, had reasonable cause to believe
           that his or her conduct was unlawful.

      b.   Action By Corporation.  The Corporation shall indemnify
           any person who was or is a party or is threatened to be
           made a party to any threatened, pending or completed
           action or suit by or in the right of the Corporation to
           procure a judgment in its favor by reason of the fact
           that he or she is or was a director, trustee, partner,
           officer, employee or agent of the Corporation, or is or
           was serving at the request of the Corporation as a
           director, officer, partner, member, trustee, employee or
           agent of another corporation, partnership, joint
           venture, limited liability company, trust or other
           enterprise or non-profit entity against expenses
           (including attorneys' fees) actually and reasonably
           incurred by him or her in connection with the defense or
           settlement of such action or suit if he or she acted in
           good faith and in a manner he or she reasonably believed
           to be in or not opposed to the best interests of the
           Corporation; except that no indemnification shall be
           made in respect of any claim, issue or matter as to
           which such person shall have been adjudged to be liable
           for negligence or misconduct in the performance of his
           or her duty to the Corporation unless and only to the
           extent that the Court of Chancery of the State of
           Delaware or the court in which such action or suit was
           brought shall determine upon application that despite
           the adjudication of liability but in view of all the
           circumstances of the case, such person is fairly and
           reasonably entitled to indemnity for such expenses which
           the Court of Chancery of the State of Delaware or such
           other court shall deem proper.

     c.    To the extent that any person referred to in paragraphs
           a. or b. above has been successful on the merits or
           otherwise in defense of any action, suit or proceeding
           referred to therein, or in defense of any claim, issue
           or matter therein, he or she shall be indemnified
           against expenses (including attorneys' fees) actually
           and reasonably incurred by him or her in connection
           therewith.

     SECTION 2. Authorization. Any indemnification under Section 1 of this
Article (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, partner, member, trustee, employee or agent is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Section 1 of this Article. Such determination shall be made: a. by the
Board of Directors by a majority vote of a quorum consisting of directors who
were not


<PAGE>


By-laws of Data Storage Systems, Inc.
A Delaware Corporation
Page 21

parties to such action, suit or proceeding, or b. if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in written opinion, or c. by the
stockholders.

     SECTION 3. Expense Advance. Expenses (including attorneys' fees) incurred
by an officer or director of the Corporation in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in the manner provided in
Section 2 of this Article upon receipt of an undertaking by or on behalf of such
officer or director to repay such amount, unless it shall ultimately be
determined that such person is entitled to be indemnified by the Corporation as
authorized in this Article. Such expenses (including attorneys' fees) incurred
by other employees or agents of the Corporation may be so paid upon such terms
and conditions, if any, as the Board of Directors deems appropriate.

     SECTION 4. Nonexclusivity. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other Sections of this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in an official capacity and as to action in another capacity
while holding such office, and shall continue as to a person who has ceased to
be a director, officer, partner, member, trustee, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

     SECTION 5. Insurance. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, partner, member, trustee, employee or agent
of another corporation, partnership, joint venture, limited liability company,
trust or other enterprise or non-profit entity against any liability asserted
against and incurred by him or her in any such capacity, or arising out of his
or her status as such, whether or not the Corporation would have the power to
indemnify such person against such liability under the provisions of this
Article or Section 145 of Title 8 of the Delaware Code relating to the General
Corporation Law of the State of Delaware.

     SECTION 6. "The Corporation". For the purposes of this Article, references
to "the Corporation" shall include the resulting corporation and, to the extent
that the Board of Directors of the resulting corporation so decides, all
constituent corporations (including any constituent of a


<PAGE>


By-laws of Data Storage Systems, Inc.

Page 22

constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers and employees or agents so that any person who is or was a
director, officer, employee or agent of such a constituent corporation or is or
was serving at the request of such constituent corporation as director, officer,
partner, member, trustee, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise or non-profit entity shall stand in the
same position under the provisions of this Article with respect to the resulting
or surviving corporation if its separate existence had continued.

     SECTION 7. Other Indemnification. The Corporation's obligation, if any, to
indemnify any person who was or is serving at its request as a director,
trustee, partner, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise or non-profit entity shall
be reduced by any amount such person may collect as indemnification from such
other corporation, partnership, joint venture, trust or other enterprise or
non-profit entity or from insurance.

     SECTION 8. Other Definitions. For purposes of this Article, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, trustee, officer, employee or agent of
the Corporation which imposes duties on, or involves services by, such director,
trustee, officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries; and a person who acted in good faith and in
a manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article.

     SECTION 9. Continuation of Indemnification. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall,
unless otherwise provided when authorized or ratified, continue as to a person
who has ceased to be a director, trustee, partner, officer, employee or agent
and shall inure to the benefit of the heirs, executors and administrators of
such a person.

     SECTION 10. Amendment or Repeal. Neither the amendment nor repeal of this
Article nor the adoption of any provision of these By-Laws inconsistent with
this Article shall reduce, eliminate or adversely affect any right or protection
hereunder of any person in respect of any act or omission occurring prior to the
effectiveness of such amendment, repeal or adoption.

the purpose or purposes in general terms for which the meeting is called shall,
not less than ten (10) days, or such longer period as shall be provided by law,
the Certificate of Incorporation, these By-Laws, or otherwise, and not more than
sixty (60) days before such meeting, be served upon or mailed to each
stockholder entitled to vote thereat, at the address of such stockholder as it
appears upon the stock records of the Corporation or, if such stockholder shall
have filed with the Secretary of the Corporation a written request that notices
be mailed to some other address, then to the address designated in such request.

     Notice of the hour, date, place and purpose of any meeting of stockholders
may be dispensed with if every stockholder entitled to vote thereat shall attend
either in person or by proxy and shall not, at the beginning of the meeting,
object to the holding of such meeting because the meeting has not been lawfully
called or convened, or if every absent stockholder entitled to such notice shall
in writing, filed with the records of the meeting, either before or after the
holding thereof, waive such notice.

     SECTION 5. Quorum and Adjournments. Except as otherwise provided by law or
by the Certificate of Incorporation, the presence in person or by proxy at any
meeting of stockholders of the holders of a majority of the shares of the
capital stock of the Corporation issued and outstanding and entitled to vote
thereat, shall be requisite and shall constitute a quorum. If two or more
classes of stock are entitled to vote as separate classes upon any question,
then, in the case of each such class, a quorum for the consideration of such
question shall, except as otherwise provided by law or by the Certificate of
Incorporation, consist of *** of all stock of that class issued, outstanding and
entitled to vote. If a majority of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote thereat or, where a
larger quorum is required, such quorum, shall not be represented at any meeting
of the stockholders regularly called, the holders of *** of the shares present
or represented by proxy and entitled to vote thereat shall have power to adjourn
the meeting to another time, or to another time and place, without notice other
than announcement of adjournment at the meeting, and there may be successive
adjournments for like cause and in like manner until the requisite amount of
shares entitled to vote at such meeting shall be represented; provided, however,
that if the adjournment is for more than thirty (30) days, notice of the hour,
date and place of the adjourned meeting shall be given to each stockholder
entitled to vote thereat. Subject to the requirements of law and the Certificate
of Incorporation, on


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 3

any issue on which two or more classes of stock are entitled to vote separately,
no adjournment shall be taken with respect to any class for which a quorum is
present unless the Chairman of the meeting otherwise directs. At any meeting
held to consider matters which were subject to adjournment for want of a quorum
at which the requisite amount of shares entitled to vote thereat shall be
represented, any business may be transated which might have been transacted at
the meeting as originally noticed.

     SECTION 6. Votes; Proxies. Except as otherwise provided in the Certificate
of Incorporation, at each meeting of stockholders, every stockholder of record
at the closing of the transfer books, if closed, or on the date set by the Board
of Directors for the determination of stockholders entitled to vote at such
meeting, shall have one vote for each share of stock entitled to vote which is
registered in such stockholder's name on the books of the Corporation, and, in
the election of directors, may vote cumulatively to the extent, if any, and in
the manner authorized in the Certificate of Incorporation.

     At each such meeting every stockholder entitled to vote shall be entitled
to do so in person, or by proxy appointed by an instrument in writing or as
otherwise permitted by law subscribed by such stockholder and bearing a date not
more than three (3) years prior to the meeting in question, unless said
instrument provides for a longer period during which it is to remain in force. A
duly executed proxy shall be irrevocable if it states that it is irrevocable and
if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power. A proxy may be made irrevocable regardless of
whether the interest with which it is coupled is an interest in the stock itself
or any interest in the Corporation generally. A stockholder may revoke any proxy
which is not irrevocable by attending the meeting and voting in person or by
filing with the Secretary of the Corporation an instrument in writing or as
otherwise permitted by law revoking the proxy or another duly executed proxy
bearing a later date.

     Voting at meetings of stockholders need not be by written ballot and,
except as otherwise provided by law, need not be conducted by inspectors of
election unless so determined by the Chairman of the meeting or by the holders
of shares of stock having a majority of the votes which could be cast by the
holders of all outstanding shares of stock entitled to vote thereon which are
present in person or represented by proxy at such meeting. If it is required or
determined that inspectors of election be appointed, the Chairman shall appoint
two inspectors of election, who shall first take and subscribe an oath or
affirmation faithfully to execute the duties of inspectors at such meeting with
strict impartiality and according to the best of their ability. The inspectors
so appointed shall take charge of the polls and, after the balloting, shall make
a certificate of the


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 4

result of the vote taken. No director or candidate for the office of director
shall be appointed as such inspector.

     At any meeting at which a quorum is present, a plurality of the votes
properly cast for election to fill any vacancy on the Board of Directors shall
be sufficient to elect a candidate to fill such vacancy, and a majority of the
votes properly cast upon any other question shall decide the question, except in
any case where a larger vote is required by law, the Certificate of
Incorporation, these By-Laws, or otherwise.

     SECTION 7. Organization. The Chairman of the Board, if there be one, or in
his or her absence the Vice Chairman, or in the absence of a Vice Chairman, the
President, or in the absence of the President, a Vice President, shall call
meetings of the stockholders to order and shall act as chairman thereof. The
Secretary of the Corporation, if present, shall act as secretary of all meetings
of stockholders, and, in his or her absence, the presiding officer may appoint a
secretary.

     SECTION 8. Consent of Stockholders in Lieu of Meeting. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
by the Delaware General Corporation Law to be taken at any annual or special
meeting of the stockholders of the Corporation, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in Delaware, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

     Every written consent shall bear the date of signature of each stockholder
who signs the consent and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty (60) days of the
earliest dated consent delivered in the manner required by this section to the
Corporation, written consents signed by a sufficient number of stockholders to
take action are delivered to the corporation by delivery to its registered
office in Delaware, its principal place of business, or an officer or agent of
the Corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the Corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.

     Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. In the event that the action which is consented
to is such as would have required the filing of a certificate under any section
of the Delaware General Corporation Law other than Section 228 thereof, if such
action had been voted on by stockholders at a meeting thereof, the certificate
filed under such other section shall state, in lieu of any statement required by
such section concerning any vote of stockholders, that written consent has been
given in accordance with Section 228 of the Delaware General Corporation Law,
and that written notice has been given as provided in such Section 228.

                              ARTICLE IV DIRECTORS
                             ---------------------

     SECTION 1. Number. The business and affairs of the Corporation shall be
conducted and managed by a Board of Directors consisting of not less than one
director, none of whom needs to be a stockholder. The number of directors for

     At each annual meeting of stockholders, the stockholders shall elect
directors. Each director so elected shall hold office, subject to the provisions
of law, the Certificate of Incorporation, these By-Laws, or otherwise, until the
next annual meeting of stockholders or until his or her successor is elected and

     At any time during any year, except as otherwise provided by law, the
Certificate of Incorporation, these By-Laws, or otherwise, the number of
directors may be increased or reduced, in each case by vote of a majority of the
stock issued and outstanding and present in person or represented by proxy and
entitled to vote for the election of directors or a majority of the directors in
office at the time of such increase or decrease, regardless of whether such
majority constitutes a quorum.

     SECTION 2. Term of Office. Each director shall hold office until the next
annual meeting of stockholders and until his or her successor is duly elected
and qualified or until his or her earlier death or resignation, subject to the
right of the stockholders at any time to remove any director or directors as

     SECTION 3. Vacancies. If any vacancy shall occur among the directors, or if
the number of directors shall at any time be increased, the directors then in
office, although less than a quorum, by a majority vote may fill the vacancies
or newly-

created directorships, or any such vacancies or newly-created directorships may
be filled by the stockholders at any meeting.

     SECTION 4. Removal by Stockholders. Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the holders of record of the
capital stock of the Corporation entitled to vote for the election of directors
may, by a majority vote, remove any director or directors, with or without
cause, and, in their discretion, elect a new director or directors in place
thereof.

waiver of notice of any meeting. Meetings may be held at any time upon the call
of the Chairman of the Board, if there be one, or the President or any two (2)
of the directors in office by oral, telegraphic, telex, telecopy or other form
of electronic transmission, or written notice, duly served or sent or mailed to
each director not less than twenty-four (24) hours before such meeting, except
that, if mailed, not less than *** (***) hours before such meeting.

     Meetings may be held at any time and place without notice if all the
directors are present and do not object to the holding of such meeting for lack
of proper notice or if those not present shall, in writing or by telegram,
telex, telecopy or other form of electronic transmission, waive notice thereof.
A regular meeting of the Board may be held without notice immediately following
the annual meeting of stockholders at the place where such meeting is held.
Regular meetings of the Board may also be held without notice at such time and
place as shall from time to time be determined by resolution of the Board.
Except as otherwise provided by law, the Certificate of Incorporation or
otherwise, neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors or any committee thereof
need be specified in any written waiver of notice.

     Members of the Board of Directors or any committee thereof may participate
in a meeting of such Board or committee by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other and participation in a meeting pursuant to the
foregoing provisions shall constitute presence in person at the meeting.

     SECTION 6.        Votes.  Except as otherwise provided by law,
the Certificate of Incorporation or otherwise, the vote of the


<PAGE>


By-laws of Data Archive Services, Inc.

shall be the act of the Board of Directors.

     SECTION 7. Quorum and Adjournment. Except as otherwise provided by law, the
Certificate of Incorporation or otherwise, a majority of the directors shall
constitute a quorum for the transaction of business. If at any meeting of the
Board there shall be less than a quorum present, a majority of those present may

the adjournment at the meeting, and at such adjourned meeting at which a quorum
is present any business may be transacted which might have been transacted at
the meeting as originally noticed.

     SECTION 8. Compensation. Directors shall receive compensation for their
services, as such, and for service on any Committee of the Board of Directors,
as fixed by resolution of the Board of Directors and for expenses of attendance
at each regular or special meeting of the Board or any Committee thereof.
Nothing in this Section shall be construed to preclude a director from serving
the Corporation in any other capacity and receiving compensation therefor.

     SECTION 9. Action By Consent of Directors. Any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee. Such consent shall be
treated as a vote adopted at a meeting for all purposes. Such consents may be
executed in one or more counterparts and not every Director or committee member
need sign the same counterpart.

Directors.

     SECTION 15. Bonds. The Board of Directors may require any officer of the

                        ARTICLE VII CERTIFICATES OF STOCK
                       -----------------------------------

     SECTION 1. Form and Execution of Certificates. The interest of each
stockholder of the Corporation shall be evidenced by a certificate or
certificates for shares of stock in such form as the Board of Directors may from
time to time prescribe. The certificates of stock of each class shall be
consecutively numbered and signed by the Chairman or Vice Chairman of the Board,
if any, the President, an Executive Vice President or a Vice President and by
the Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer
of the Corporation, and may be countersigned and registered in such manner as
the Board of Directors may by resolution prescribe, and shall bear the corporate
seal or a printed or engraved facsimile thereof. Where any such certificate is
signed by a transfer agent or transfer clerk acting on behalf of the
Corporation, the signatures of any such Chairman, Vice Chairman, President,
Executive Vice President, Vice President, Treasurer, Assistant Treasurer,
Secretary or Assistant Secretary may be facsimiles, engraved or printed. In case
any officer or officers, who shall have signed, or whose facsimile signature or
signatures shall have been used on, any such certificate or certificates, shall
cease to be such officer or officers, whether because of death, resignation or
otherwise, before such certificate or certificates shall have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the person or persons who signed such


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 14

certificate or certificates or whose facsimile signature or signatures shall
have been used thereon had not ceased to be such officer or officers.

     In case the corporate seal which has been affixed to, impressed on, or
reproduced in any such certificate or certificates shall cease to be the seal of
the Corporation before such certificate or certificates have been delivered by
the Corporation, such certificate or certificates may nevertheless be issued and
delivered by the Corporation as though the seal affixed thereto, impressed
thereon or reproduced therein had not ceased to be the seal of the Corporation.

     Every certificate for shares of stock which are subject to any restriction
on transfer pursuant to law, the Certificate of Incorporation, these By-Laws, or
any agreement to which the Corporation is a party, shall have the restriction
noted conspicuously on the certificate, and shall also set forth, on the face or
back, either the full text of the restriction or a statement of the existence of
such restriction and (except if such restriction is imposed by law) a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

     Every certificate issued when the Corporation is authorized to issue more
than one class or series of stock shall set forth on its face or back either the
full text of the preferences, voting powers, qualifications, and special and
relative rights of the shares of each class and series authorized to be issued,
or a statement of the existence of such preferences, powers, qualifications and
rights, and a statement that the Corporation will furnish a copy thereof to the
holder of such certificate upon written request and without charge.

     SECTION 2. Transfer of Shares. The shares of the stock of the Corporation
shall be transferred on the books of the Corporation by the holder thereof in
person or by his or her attorney lawfully constituted, upon surrender for
cancellation of certificates for the same number of shares, with an assignment
and power of transfer endorsed thereon or attached thereto, duly executed, with
such proof or guaranty of the authenticity of the signature as the Corporation
or its agents may reasonably require. The Corporation shall be entitled to treat
the holder of record of any share or shares of stock as the holder in fact
thereof and accordingly shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person
whether or not it shall have express or other notice thereof, save as expressly
provided by law or by the Certificate of Incorporation. It shall be the duty of
each stockholder to notify the Corporation of his or her post office address.

     SECTION 3. Closing of Transfer Books. The stock transfer books of the
Corporation may, if deemed appropriate by the Board of Directors, be closed for
such length of time not exceeding fifty (50) days as the Board may determine,
preceding the date of any meeting of stockholders or the date for the payment of
any dividend or the date for the allotment of rights or the date when any
issuance, change, conversion or exchange of capital stock shall go into effect,
during which time no transfer of stock on the books of the Corporation may be
made.

     SECTION 4. Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
directors and which record date: (a) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than sixty (60) nor less than ten (10)
days before the date of such meeting; (b) in the case of determination of
stockholders entitled to express consent to corporate action in writing without
a meeting, shall, unless otherwise required by law, the Certificate of
Incorporation or otherwise, not be more than ten (10) days from the date upon
which the resolution fixing the record date is adopted by the Board of
Directors; and (c) in the case of any other action, shall not be more than sixty
(60) days prior to such other action. If no record date is fixed: (a) the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or, if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held; (b) the record
date for determining stockholders entitled to express consent to corporate
action in writing without a meeting when no prior action of the Board of
Directors is required by law, shall be the first date on which a signed written
consent setting forth the action take or proposed to be taken is delivered to
the Corporation in accordance with applicable law, or, if prior action by the
Board of Directors is required by law, shall be at the close of business on the
day on which the Board of Directors adopts the resolution taking such prior
action; and (c) the record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto. A determination of
stockholders of


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 16

record entitled to notice of or to vote at a meeting of stockholders shall apply
to any adjournment of the meeting; provided, however, that the Board of
Directors may fix a new record date for the adjourned meeting.

     SECTION 5.        Lost or Destroyed Certificates.  In case of
the loss or destruction of any certificate of stock, a new
certificate may be issued under the following conditions:

     a.    The owner of said certificate shall file with the
           Secretary or any Assistant Secretary of the Corporation
           an affidavit giving the facts in relation to the
           ownership, and in relation to the loss or destruction of
           said certificate, stating its number and the number of
           shares represented thereby; such affidavit shall be in
           such form and contain such statements as shall satisfy
           the President, any Executive Vice President, Vice
           President, the Secretary, any Assistant Secretary, the
           Treasurer or any Assistant Treasurer, that said
           certificate has been accidentally destroyed or lost, and
           that a new certificate ought to be issued in lieu
           thereof.  Upon being so satisfied, any such officer may
           require such owner to furnish the Corporation a bond in
           such penal sum and in such form as he or she may deem
           advisable, and with a surety or sureties approved by him
           or her, to indemnify and save harmless the Corporation
           from any claim, loss, damage or liability which may be
           occasioned by the issuance of a new certificate in lieu
           thereof.  Upon such bond being so filed, if so required,
           a new certificate for the same number of shares shall be
           issued to the owner of the certificate so lost or
           destroyed; and the transfer agent and registrar, if any,
           of stock shall countersign and register such new
           certificate upon receipt of a written order signed by
           any such officer, and thereupon the Corporation will
           save harmless said transfer agent and registrar in the
           premises.  In case of the surrender of the original
           certificate, in lieu of which a new certificate has been
           issued, or the surrender of such new certificate, for
           cancellation, the bond of indemnity given as a condition
           of the issue of such new certificate may be surrendered;
           or

     b.    The Board of Directors of the Corporation may by
           resolution authorize and direct any transfer agent or
           registrar of stock of the Corporation to issue and
           register respectively from time to time without further
           action or approval by or on behalf of the Corporation
           new certificates of stock to replace certificates
           reported lost, stolen or destroyed upon receipt of an
           affidavit of loss and bond of indemnity in form and
           amount and with surety satisfactory to such transfer

thereunto authorized from time to time by the Board of Directors, which may in

President, any Vice President, the Secretary, any Assistant Secretary, the
Treasurer or any Assistant Treasurer. The Board of Directors may, however, in
its discretion, require any or all such instruments to be signed by any two or
more of such officers, or may permit any or all of such instruments to be signed
by such other officer or officers, agent or agents, as it shall be thereunto
authorize from time to time.

     SECTION 3. Execution of Proxies. The President, any Executive Vice
President or any Vice President, and the Secretary, the Treasurer, any Assistant
Secretary or any Assistant Treasurer, or any other officer designated by the

                         ARTICLE IX INSPECTION OF BOOKS

allowed, to what extent and at what time and places and under what conditions
and regulations, the accounts and books of the Corporation (except such as may

                           ARTICLE XII INDEMNIFICATION
                          -----------------------------

     SECTION 1.        Indemnification.

     a.    Action By Third Party.  The Corporation shall indemnify
           and hold harmless, to the fullest extent permitted by
           applicable law as it presently exists or may hereafter
           be amended, any person who was or is a party or is
           threatened to be made a party or is otherwise involved
           in any threatened, pending or completed action, suit or
           proceeding, whether civil, criminal, administrative or
           investigative (other than an action by or in the right
           of the Corporation) by reason of the fact that he, or a
           person for whom he or she is the legal representative,
           is or was a director, officer, employee or agent of the
           Corporation, or is or was serving at the request of the
           Corporation as a director, officer, partner, member,
           trustee, employee or agent of another corporation,
           partnership, joint venture, limited liability company,
           trust or other enterprise or non-profit entity against
           all liability, losses, expenses (including attorneys'
           fees), judgments, fines, and amounts paid in settlement
           actually and reasonably incurred by him or her in
           connection with such action, suit or proceeding if he or
           she acted in good faith and in a manner he or she
           reasonably believed to be in or not opposed to the best
           interest of the Corporation, and, with respect to any
           criminal action or proceeding, had no reasonable cause
           to believe his conduct was unlawful.  The termination of
           any action, suit or proceeding by judgment, order,
           settlement, conviction, or upon a plea of nolo
           contendere or its equivalent, shall not, of itself,
           create a presumption that the person did not act in good
           faith and in a manner which he or she reasonably
           believed to be in or not opposed to the best interest of
           the Corporation, and, with respect to any criminal


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 20

           action or proceeding, had reasonable cause to believe
           that his or her conduct was unlawful.

      b.   Action By Corporation.  The Corporation shall indemnify
           any person who was or is a party or is threatened to be
           made a party to any threatened, pending or completed
           action or suit by or in the right of the Corporation to
           procure a judgment in its favor by reason of the fact
           that he or she is or was a director, trustee, partner,
           officer, employee or agent of the Corporation, or is or
           was serving at the request of the Corporation as a
           director, officer, partner, member, trustee, employee or
           agent of another corporation, partnership, joint
           venture, limited liability company, trust or other
           enterprise or non-profit entity against expenses
           (including attorneys' fees) actually and reasonably
           incurred by him or her in connection with the defense or
           settlement of such action or suit if he or she acted in
           good faith and in a manner he or she reasonably believed
           to be in or not opposed to the best interests of the
           Corporation; except that no indemnification shall be
           made in respect of any claim, issue or matter as to
           which such person shall have been adjudged to be liable
           for negligence or misconduct in the performance of his
           or her duty to the Corporation unless and only to the
           extent that the Court of Chancery of the State of
           Delaware or the court in which such action or suit was
           brought shall determine upon application that despite
           the adjudication of liability but in view of all the
           circumstances of the case, such person is fairly and
           reasonably entitled to indemnity for such expenses which
           the Court of Chancery of the State of Delaware or such
           other court shall deem proper.

     c.    To the extent that any person referred to in paragraphs
           a. or b. above has been successful on the merits or
           otherwise in defense of any action, suit or proceeding
           referred to therein, or in defense of any claim, issue
           or matter therein, he or she shall be indemnified
           against expenses (including attorneys' fees) actually
           and reasonably incurred by him or her in connection
           therewith.

     SECTION 2.        Authorization.  Any indemnification under
Section 1 of this Article (unless ordered by a court) shall be
made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director,
officer, partner, member, trustee, employee or agent is proper in
the circumstances because such person has met the applicable
standard of conduct set forth in Section 1 of this Article.  Such
determination shall be made: a. by the Board of Directors by a
majority vote of a quorum consisting of directors who were not


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 21

parties to such action, suit or proceeding, or b. if such a
quorum is not obtainable, or, even if obtainable, a quorum of
disinterested directors so directs, by independent legal counsel
in written opinion, or c. by the stockholders.

     SECTION 3. Expense Advance. Expenses (including attorneys' fees) incurred
by an officer or director of the Corporation in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in the manner provided in
Section 2 of this Article upon receipt of an undertaking by or on behalf of such
officer or director to repay such amount, unless it shall ultimately be
determined that such person is entitled to be indemnified by the Corporation as
authorized in this Article. Such expenses (including attorneys' fees) incurred
by other employees or agents of the Corporation may be so paid upon such terms
and conditions, if any, as the Board of Directors deems appropriate.

     SECTION 4. Nonexclusivity. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other Sections of this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in an official capacity and as to action in another capacity
while holding such office, and shall continue as to a person who has ceased to
be a director, officer, partner, member, trustee, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

     SECTION 5. Insurance. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, partner, member, trustee, employee or agent
of another corporation, partnership, joint venture, limited liability company,
trust or other enterprise or non-profit entity against any liability asserted
against and incurred by him or her in any such capacity, or arising out of his
or her status as such, whether or not the Corporation would have the power to
indemnify such person against such liability under the provisions of this
Article or Section 145 of Title 8 of the Delaware Code relating to the General
Corporation Law of the State of Delaware.

     SECTION 6.        "The Corporation".  For the purposes of this
Article, references to "the Corporation" shall include the
resulting corporation and, to the extent that the Board of
Directors of the resulting corporation so decides, all
constituent corporations (including any constituent of a


<PAGE>


By-laws of Data Archive Services, Inc.
A Delaware Corporation
Page 22

constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers and employees or agents so that any person who is or was a
director, officer, employee or agent of such a constituent corporation or is or
was serving at the request of such constituent corporation as director, officer,
partner, member, trustee, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise or non-profit entity shall stand in the
same position under the provisions of this Article with respect to the resulting
or surviving corporation if its separate existence had continued.

     SECTION 7. Other Indemnification. The Corporation's obligation, if any, to
indemnify any person who was or is serving at its request as a director,
trustee, partner, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise or non-profit entity shall
be reduced by any amount such person may collect as indemnification from such
other corporation, partnership, joint venture, trust or other enterprise or
non-profit entity or from insurance.

     SECTION 8. Other Definitions. For purposes of this Article, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, trustee, officer, employee or agent of
the Corporation which imposes duties on, or involves services by, such director,
trustee, officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries; and a person who acted in good faith and in
a manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article.

     SECTION 9. Continuation of Indemnification. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall,
unless otherwise provided when authorized or ratified, continue as to a person
who has ceased to be a director, trustee, partner, officer, employee or agent
and shall inure to the benefit of the heirs, executors and administrators of
such a person.

     SECTION 10. Amendment or Repeal. Neither the amendment nor repeal of this
Article nor the adoption of any provision of these By-Laws inconsistent with
this Article shall reduce, eliminate or adversely affect any right or protection
hereunder of any person in respect of any act or omission occurring prior to the
effectiveness of such amendment, repeal or adoption.

SECTION 1.01.     DEFINITIONS.

                  "Acquired Debt" means, with respect to any specified Person,
(a) Indebtedness of any other Person existing at the time such other Person
merged with or into or became a Subsidiary of such specified Person, including
Indebtedness incurred in connection with, or in contemplation of, such other

and (b) Indebtedness encumbering any asset acquired by such specified Person.

                  "Acquisition EBITDA" means, as of any date of determination,
with respect to an Acquisition EBITDA Entity, the sum of (a) EBITDA of such
Acquisition EBITDA Entity for its last fiscal quarter for which financial

fiscal year for which financial statements are available), plus (b) 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

                  "Acquisition EBITDA Entity" means, as of any date of

of which is three minus the number of months (and/or any portion thereof ) in
such most recent fiscal quarter for which the financial results of such
Acquisition EBITDA Entity are included in the EBITDA of the Company and its
Restricted Subsidiaries under clause (a) above, and (ii) the

Board of Directors) and (b) the present value (discounted at the rate of
interest implicit in such transaction) of the total obligations of the lessee
for rental payments during the remaining terms of the lease included in such
Sale and Leaseback Transaction (including any period for which such lease has
been extended).

                  "Bankruptcy Law" means Title 11, U.S. Code or any similar 
federal or state law for the relief of debtors.

                  "Board of Directors" means the Board of Directors of the

participations, rights or other equivalents (however designated) of corporate
stock, including, without limitation, with respect to partnerships, partnership

facsimile form. An Officer of each Guarantor shall sign the Subsidiary Guarantee
for such Guarantor by manual or facsimile signature.

           If an Officer of the Company or a Guarantor whose signature is on a
Note or a Subsidiary Guarantee, as the case may be, no longer holds that office
at the time the Note is authenticated, the Note or the Subsidiary Guarantee, as
the case may be, shall nevertheless be valid.

           A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature of the Trustee shall be conclusive evidence that
the Note has been authenticated under this Indenture. The form of Trustee's
certificate of authentication to be borne by the Notes shall be substantially as
set forth in Exhibit A hereto.

           The Trustee shall, upon a written order of the Company signed by two

principal amount of Notes outstanding at any time shall not exceed $__,000,000
except as provided in Section 2.07 hereof.

           The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. Unless limited by the terms of such appointment,
an authenticating agent may authenticate Notes whenever the Trustee may do so.

presented for payment ("Paying Agent"). The Registrar shall keep a register of
the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term "Paying
Agent" includes any additional paying agent. The Company may change any Paying
Agent, Registrar or co-registrar without prior notice to any Holder of a Note.
The Company shall notify the Trustee and the Trustee shall notify the Holders of
the Notes of the name and address of any Agent not a party to this Indenture.
The Company or any Guarantor may act as Paying Agent, Registrar or co-registrar.
The Company shall enter into an appropriate agency agreement with any Agent not
a party to this Indenture, which shall be subject to any obligations imposed by
the provisions of the TIA. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall notify the Trustee of the
name and address of any such Agent. If the Company fails to maintain a Registrar
or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as
such, and shall be entitled to appropriate compensation in accordance with
Section 7.07 hereof.

and agent for service of notices and demands in connection with the Notes.

SECTION 2.04.   PAYING AGENT TO HOLD MONEY IN TRUST.

           The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent shall hold in trust for the benefit of
the Holders of the Notes or the Trustee all money held by the Paying Agent for
the payment of principal of, premium, if any, and interest on the Notes, and
shall notify the Trustee of any Default by the Company or the Guarantors in
making any such payment. While any such Default continues, the Trustee may
require a Paying Agent to pay all money held by it to the Trustee. The Company
at any time may require a Paying Agent to pay all money held by it to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or a Guarantor) shall have no further liability for the money delivered
to the Trustee. If the Company or a Guarantor acts as Paying Agent, it shall
segregate and hold in a separate trust fund for the benefit of the Holders of
the Notes, subject to Article 10 hereof, all money held by it as Paying Agent.
Upon any bankruptcy or reorganization proceeding relating to the Company or a
Guarantor, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05.   LISTS OF HOLDERS OF THE NOTES.

           The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders of the Notes and shall otherwise comply with TIA ss. 312(a). If the
Trustee is not the Registrar, the Company and/or the Guarantors shall furnish to
the Trustee at least seven Business Days before each interest payment date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Holders of the Notes, including the aggregate principal amount of
the Notes held by each thereof, and the Company and each Guarantor shall
otherwise comply with TIA ss. 312(a).

SECTION 2.06.   TRANSFER AND EXCHANGE.

           When Notes are presented to the Registrar with a request to register
the transfer or to exchange them for an equal principal amount of Notes of other
denominations, the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met; provided, however, that any Note
presented or surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by a written instruction of transfer in form
satisfactory to the Registrar and the Trustee duly executed by the Holder
thereof or by his attorney duly authorized in writing. To permit registrations
of transfer and exchanges, the Company shall issue and the Trustee shall
authenticate Notes at the Registrar's request, subject to such rules as the
Trustee may reasonably require.

           Neither the Company nor the Registrar shall be required to (a) issue,
register the transfer of or exchange Notes during a period beginning at the
opening of business on a Business Day 15 days before the day of any selection of
Notes for redemption under Section 3.02 hereof and ending at the close of
business on the day of selection or (b) register the transfer of or exchange any
Note so selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part.

           No service fee shall be charged to any Holder of a Note for any
registration of transfer or exchange (except as otherwise expressly permitted
herein), but the Company may require payment of a sum sufficient to cover any
transfer tax or similar governmental charge payable in connection therewith
(other than such transfer tax or similar governmental charge payable upon
exchanges pursuant to Sections 2.10, 3.06 or 9.05 hereof, which shall be paid by
the Company).

           Prior to due presentment to the Trustee for registration of the
transfer of any Note, the Trustee, any Agent, the Company and each Guarantor may
deem and treat the Person in whose name any Note is registered as the absolute
owner of such Note for the purpose of receiving payment of principal of,
premium, if any, and interest on such Note and for all other purposes
whatsoever, whether or not such Note is overdue, and none of the Trustee, any
Agent, the Company or any Guarantor shall be affected by notice to the contrary.

           Notwithstanding any other provision in this Indenture, no Global Note
may be transferred to, or registered or exchanged for Notes registered in the
name of, any Person other than the Depositary for such Global Note or any
nominee thereof, and no such transfer may be registered, unless (a) such
Depositary (i) notifies the Company that it is unwilling or unable to continue
as Depositary for such Global Note or (ii) ceases to be a clearing agency
registered under the Exchange Act, (b) the Company delivers to the Trustee an
Officers' Certificate stating that such Global Note shall be so transferable,
registrable, and exchangeable, and such transfers shall be registrable, or (c)
there shall have occurred and be continuing an Event of Default with respect to
the Notes evidenced by such Global Note. Notwithstanding any other provision in
this Indenture, a Global Note to which the restriction set forth in the
preceding sentence shall have ceased to apply may be transferred only to, and
may be registered and exchanged for Notes registered only in the name or names
of, such Person or Persons as the Depositary for such Global Note shall have
directed and no transfer thereof other than such a transfer may be registered.
Every Note authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Note to which the restriction set forth in
the first sentence of this paragraph shall apply, whether pursuant to this
Section 2.06 or otherwise, shall be authenticated and delivered in the form of,
and shall be, a Global Note.

SECTION 2.07.   REPLACEMENT NOTES.

           If any mutilated Note is surrendered to the Trustee, or the Company
and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Note, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate a
replacement Note (accompanied by a notation of the Subsidiary Guarantees duly
endorsed by each Guarantor) if the Trustee's requirements for replacements of
Notes are met. If required by the Trustee, the Company or the Guarantors, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee, the Company and the Guarantors to protect the Company, the
Guarantors, the Trustee, any Agent or any authenticating agent from any loss
which any of them may suffer if a Note is replaced. Each of the Company, the
Guarantors and the Trustee may charge for its expenses in replacing a Note.


NYMAIN01 Doc: 159158_2
                                       19

<PAGE>

           Every replacement Note is an additional obligation of the Company and
the Guarantors and shall be entitled to all of the benefits of this Indenture
equally and ratably with all other Notes duly issued hereunder.

SECTION 2.08.   OUTSTANDING NOTES.

           The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.08 as not outstanding. If a
Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Note is
held by a bona fide purchaser. If the principal amount of any Note is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it
ceases to accrue. Subject to Section 2.09 hereof, a Note does not cease to be
outstanding because the Company, a Guarantor, a Subsidiary of the Company or a
Guarantor or an Affiliate of the Company or a Guarantor holds the Note.

SECTION 2.09.   TREASURY NOTES.

           In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, any Guarantor, any of their respective Subsidiaries or any Affiliate of
the Company or any Guarantor shall be considered as though not outstanding,
except that for purposes of determining whether the Trustee shall be protected
in relying on any such direction, waiver or consent, only Notes which the
Trustee knows to be so owned shall be so considered. Notwithstanding the
foregoing, Notes that are to be acquired by the Company, any Guarantor, any
Subsidiary of the Company or any Guarantor or an Affiliate of the Company or any
Guarantor pursuant to an exchange offer, tender offer or other agreement shall
not be deemed to be owned by the Company, such Guarantor, a Subsidiary of the
Company or such Guarantor or an Affiliate of the Company or such Guarantor until
legal title to such Notes passes to the Company, such Guarantor, such Subsidiary
or such Affiliate, as the case may be.

SECTION 2.10.   TEMPORARY NOTES.

           Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes (accompanied by a
notation of the Subsidiary Guarantees duly endorsed by each Guarantor).
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company and the Trustee consider appropriate for
temporary Notes. Without unreasonable delay, the Company shall prepare and the
Trustee, upon receipt of the written order of the Company signed by two Officers
of the Company, shall authenticate definitive Notes (accompanied by a notation
of the Subsidiary Guarantees duly endorsed by each Guarantor) in exchange for
temporary Notes. Until such exchange, temporary Notes shall be entitled to the
same rights, benefits and privileges as definitive Notes.

SECTION 2.11.   CANCELLATION.

           The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall destroy canceled Notes
(subject to the record retention requirement of the Exchange Act), unless the
Company directs canceled Notes to be returned to it. The Company may not issue
new Notes to replace Notes that it has redeemed or paid or that have been
delivered to the Trustee for cancellation. All canceled Notes held by the
Trustee shall be destroyed and certification of their destruction delivered to
the Company, unless by a written order, signed by two Officers of the Company,
the Company shall direct that canceled Notes be returned to it.

SECTION 2.12.   DEFAULTED INTEREST.

           If the Company and the Guarantors default in a payment of interest on
the Notes, the Company or any such Guarantor (to the extent of its obligations
under its Subsidiary Guarantee) shall pay the defaulted interest in any lawful
manner plus, to the extent lawful, interest payable on the defaulted interest,
to the Persons who are Holders of the Notes on a subsequent special record date,
which date shall be at the earliest practicable date but in all events at least
five Business Days prior to the payment date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall fix or cause to be
fixed each such special record date and payment date, and shall, promptly
thereafter, notify the Trustee of any such date. At least 15 days before the
special record date, the Company (or the Trustee, in the name of and at the
expense of the Company) shall mail to Holders of the Notes a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

SECTION 2.13.   RECORD DATE.

           The record date for purposes of determining the identity of Holders
of the Notes entitled to vote or consent to any action by vote or consent
authorized or permitted under this Indenture shall be determined as provided for
in TIA ss. 316(c).

SECTION 2.14.   CUSIP NUMBER.

           The Company in issuing the Notes may use a "CUSIP" number and, if it
does so, the Trustee shall use the CUSIP number in notices of redemption or
exchange as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Notes and that reliance may be placed
only on the other identification numbers printed on the Notes. The Company will
promptly notify the Trustee of any change in the CUSIP number.

SECTION 2.15.   COMPUTATION OF INTEREST.

           Interest will be computed on the basis of a 360-day year consisting
of twelve 30-day months.

                                    ARTICLE 3
                        REDEMPTION AND OFFERS TO PURCHASE

SECTION 3.01.   NOTICES TO TRUSTEE.

           If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 45 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the Section of this Indenture pursuant
to which the redemption shall occur, (ii) the redemption date, (iii) the
principal amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02.   SELECTION OF NOTES TO BE REDEEMED.

           If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed among the applicable Holders of
the Notes 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 in accordance with any other
method the Trustee considers fair and appropriate, provided that no Notes of
$1,000 or less shall be redeemed in part. In the event of partial redemption by
lot, the particular Notes to be redeemed shall be selected, unless otherwise
provided herein, not less than 30 nor more than 60 days prior to the redemption
date by the Trustee from the outstanding Notes not previously called for
redemption.

           The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

SECTION 3.03.   NOTICE OF REDEMPTION.

           At least 30 days but not more than 60 days before a redemption date,
the Company shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Notes are to be redeemed at its registered
address.

           The notice shall identify the Notes to be redeemed and shall state:

                (a)   the redemption date;


NYMAIN01 Doc: 159158_2
                                       22

<PAGE>

                (b)   the redemption price (including accrued interest to the 
      redemption date);

                (c) if any Note is being redeemed in part, the portion of the
      principal amount of such Note to be redeemed and that, after the
      redemption date upon surrender of such Note, a new Note or Notes in
      principal amount equal to the unredeemed portion shall be issued upon
      cancellation of the original Note;

                (d)   the name and address of the Paying Agent;

                (e)   that Notes called for redemption must be surrendered to 
      the Paying Agent to collect the redemption price;

                (f) that, unless the Company defaults in making such redemption
      payment, interest on Notes called for redemption shall cease to accrue on
      and after the redemption date;

                (g)   the paragraph of the Notes and/or Section of this 
      Indenture pursuant to which the Notes called for redemption are being 
      redeemed; and

                (h) that no representation is made as to the correctness or
      accuracy of the CUSIP number, if any, listed in such notice or printed on
      the Notes.

           At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04.   EFFECT OF NOTICE OF REDEMPTION.

           Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional. On and after the redemption date, unless the Company defaults in
the payment of the redemption price, interest will cease to accrue on the Notes
or portions thereof called for redemption and all rights of Holders with respect
to such Notes will terminate except for the right to receive payment of the
redemption price upon surrender for redemption.

SECTION 3.05.   DEPOSIT OF REDEMPTION PRICE.

           One Business Day prior to the redemption date, the Company shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Notes to be redeemed on that
date. The Trustee or the Paying Agent shall promptly return to the Company any
money deposited with the Trustee or the Paying Agent by the Company in excess of
the amounts necessary to pay the redemption price of, and accrued interest on,
all Notes to be redeemed.

                                       23

<PAGE>

           If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption, whether or not such
Notes are presented for payment. If a Note is redeemed on or after an interest
record date but on or prior to the related interest payment date, then any
accrued and unpaid interest shall be paid to the Person in whose name such Note
was registered at the close of business on such record date. If any Note called
for redemption shall not be so paid upon surrender for redemption because of the
failure of the Company to comply with the preceding paragraph, interest shall be
paid on the unpaid principal, from the redemption date until such principal is
paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01
hereof.

SECTION 3.06.   NOTES REDEEMED IN PART.

           Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note (accompanied by a
notation of the Subsidiary Guarantees duly endorsed by each Guarantor) equal in
principal amount to the unredeemed portion of the Note surrendered.

SECTION 3.07.   OPTIONAL REDEMPTION.

           The Notes shall not be redeemable at the Company's option prior to
______, 2001. Thereafter, the Notes shall 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 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...................................... 100.00%

           Notwithstanding the foregoing, at any time prior to ______, 1999, 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 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.

SECTION 3.08.   MANDATORY REDEMPTION.

                                       24

<PAGE>

           Except as set forth below under Section 4.10 and Section 4.14 hereof,
the Company shall not be required to make sinking fund or redemption payments
with respect to the Notes.

SECTION 3.09.   ASSET SALE OFFERS.

           In the event that the Company shall commence an Asset Sale Offer
pursuant to Section 4.10 hereof, it shall follow the procedures specified below:

           The Asset Sale Offer shall remain open for 20 Business Days after the
Commencement Date relating to such Asset Sale Offer, except to the extent
required to be extended by applicable law (as so extended, the "Offer Period").
No later than one Business Day after the termination of the Offer Period (the
"Purchase Date"), the Company shall purchase the principal amount (the "Offer
Amount") of Notes required to be purchased in such Asset Sale Offer pursuant to
Sections 3.02 and 4.10 hereof or, if less than the Offer Amount has been
tendered, all Notes tendered in response to the Asset Sale Offer.

           If the Purchase Date is on or after an interest payment record date
and on or before the related interest payment date, any interest accrued to such
Purchase Date shall be paid to the Person in whose name a Note is registered at
the close of business on such record date, and no additional interest shall be
payable to Holders who tender Notes pursuant to the Asset Sale Offer.

           On the Commencement Date of any Asset Sale Offer, the Company shall
send or cause to be sent, by first class mail, a notice to each of the Holders,
with a copy to the Trustee. Such notice, which shall govern the terms of the
Asset Sale Offer, shall contain all instructions and materials necessary to
enable the Holders to tender Notes pursuant to the Asset Sale Offer and shall
state:

           (1)  that the Asset Sale Offer is being made pursuant to this Section
                3.09 and Section 4.10 hereof and the length of time the Asset
                Sale Offer shall remain open;

           (2)  the Offer Amount, the Purchase Price and the Purchase Date;

           (3)  that any Note not tendered or accepted for payment shall 
                continue to accrue interest;

           (4)  that, unless the Company defaults in the payment of the Purchase
                Price, any Note accepted for payment pursuant to the Asset Sale
                Offer shall cease to accrue interest after the Purchase Date;

           (5)  that Holders electing to have a Note purchased pursuant to any
                Asset Sale Offer shall be required to surrender the Note, with
                the form entitled "Option of Holder to Elect Purchase" on the
                reverse of the Note completed, to the Company, a depositary, if
                appointed by the Company, or a Paying Agent at the address
                specified in the notice prior to the close of business on the
                Business Day preceding the Purchase Date;

                                       25

<PAGE>

           (6)  that Holders shall be entitled to withdraw their election if the
                Company, depositary or Paying Agent, as the case may be,
                receives, not later than the close of business on the Business
                Day preceding the termination of the Offer Period, a telegram,
                telex, facsimile transmission or letter setting forth the name
                of the Holder, the principal amount of the Note the Holder
                delivered for purchase and a statement that such Holder is
                withdrawing his election to have the Note purchased;

           (7)  that, if the aggregate principal amount of Notes surrendered by
                Holders exceeds the Offer Amount, the Trustee shall select the
                Notes to be purchased on a pro rata basis (with such adjustments
                as may be deemed appropriate by the Company so that only Notes
                in denominations of $1,000, or integral multiples thereof, shall
                be purchased); and

           (8)  that Holders whose Notes were purchased only in part shall be
                issued new Notes equal in principal amount to the unpurchased
                portion of the Notes surrendered.

           On or before 12:00 p.m. on each Purchase Date, the Company shall
irrevocably deposit with the Trustee or Paying Agent in immediately available
funds the aggregate Purchase Price with respect to a principal amount of Notes
equal to the Offer Amount, together with accrued interest thereon, if any, to be
held for payment in accordance with the terms of this Section 3.09. On the
Purchase Date, the Company shall, to the extent lawful, (i) accept for payment,
on a pro rata basis to the extent necessary, an aggregate principal amount equal
to the Offer Amount of Notes tendered pursuant to the Asset Sale Offer, or if
less than the Offer Amount has been tendered, all Notes or portions thereof
tendered, (ii) deliver or cause the Paying Agent or depositary, as the case may
be, to deliver to the Trustee Notes so accepted and (iii) deliver to the Trustee
an Officers' Certificate stating that such Notes or portions thereof were
accepted for payment by the Company in accordance with the terms of this Section
3.09. The Company, depositary or Paying Agent, as the case may be, shall
promptly (but in any case not later than three Business Days after the Purchase
Date) mail or deliver to each tendering Holder an amount equal to the Purchase
Price with respect to the Notes tendered by such Holder and accepted by the
Company for purchase, and the Company shall promptly issue a new Note, and the
Trustee shall authenticate and mail or deliver such new Note, to such Holder,
equal in principal amount to any unpurchased portion of such Holder's Notes
surrendered. Any Note not accepted in the Asset Sale Offer shall be promptly
mailed or delivered by the Company to the Holder thereof. The Company shall
publicly announce in a newspaper of general circulation the results of the Asset
Sale Offer on the Purchase Date.

           The Asset Sale Offer shall be made by the Company in compliance with
all applicable laws, including, without limitation, Regulation 14E of the
Exchange Act and the rules thereunder, to the extent applicable, and all other
applicable federal and state securities laws.

           Each purchase pursuant to this Section 3.09 shall be made pursuant to
the provisions of the second paragraph of Section 3.05 hereof to the extent
applicable.

<PAGE>

           In the event the amount of Excess Proceeds to be applied to an Asset
Sale Offer would result in the purchase of a principal amount of Notes which is
not evenly divisible by $1,000, the Trustee shall promptly refund to the Company
the portion of such Excess Proceeds that is not necessary to purchase the
immediately lesser principal amount of Notes that is so divisible.

                                    COVENANTS

SECTION 4.01.   PAYMENT OF NOTES.

           The Company shall pay or cause to be paid the principal of, premium,
if any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Company or a Restricted
Subsidiary, holds as of 10:00 a.m. Eastern Time on the due date money deposited
by the Company in immediately available funds and designated for and sufficient
to pay all principal, premium, if any, and interest then due.

           The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal at the rate equal
to 1% per annum in excess of the then applicable interest rate on the Notes to
the extent lawful; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

SECTION 4.02.   MAINTENANCE OF OFFICE OR AGENCY.

           The Company shall maintain in the Borough of Manhattan, the City of
New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Company or any Restricted Subsidiary in respect of the
Notes and this Indenture may be served. The Company shall give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee.

           The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt

the annual information only, a report thereon by the Company's certified
independent accountants and (ii) all financial information that would be
required to be included in a Form 8-K filed with the SEC if the Company were

Trustee shall have no duty to review such documents for purposes of determining
compliance with any provisions of this Indenture.

           (a) The Company shall deliver to the Trustee, within 90 days after
the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Company and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Company and each Restricted Subsidiary has kept,
observed, performed and fulfilled its obligations under this Indenture
(including with respect to any Restricted Payments made during such year, the
basis upon which the calculations required by Section 4.07 hereof were computed,
which calculations may be based on the Company's latest available financial
statements), and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge, the Company and each
Restricted Subsidiary has kept, observed, performed and fulfilled each and every
covenant contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions of this Indenture (or,
if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he or she may have knowledge and what
action the Company and each Restricted Subsidiary, as the case may be, is taking
or proposes to take with respect thereto) and that to the best of his or her
knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of or interest, if any, on the Notes is
prohibited or if such event has occurred, a description of the event and what
action the Company and each Restricted Subsidiary, as the case may be, is taking
or proposes to take with respect thereto.

           (b) So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03 hereof shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of


NYMAIN01 Doc: 159158_2
                                       28

<PAGE>

existence thereof, it being understood that such accountants shall not be liable
directly or indirectly to any Person for any failure to obtain knowledge of any
such violation.

           (c) The Company shall, so long as any of the Notes are outstanding,
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

SECTION 4.05.   TAXES.

           The Company shall pay, and shall cause each of its Subsidiaries to
pay, prior to delinquency, all material taxes, assessments, and governmental
levies except (i) such as are contested in good faith and by appropriate
proceedings or (ii) the nonpayment of which would not materially adversely
affect the business, condition (financial or otherwise), operations, performance
or properties of the Company and its Subsidiaries, taken as a whole.

SECTION 4.06.   STAY, EXTENSION AND USURY LAWS.

           Each of the Company and the Guarantors covenants (to the extent that
it may lawfully do so) that it shall not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law wherever enacted, now or at any time hereafter in force,
that may affect the covenants or the performance of this Indenture; and each of
the Company and the Guarantors (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
shall not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law has been enacted.

SECTION 4.07.   RESTRICTED PAYMENTS.

           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 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:


NYMAIN01 Doc: 159158_2
                                       29

<PAGE>
           (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 Section 4.09 hereof; 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 this 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 this 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 this
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 covenant set forth in
Section 4.14 hereof, 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 originally issued by
the Company to First Document Storage, Inc. 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 

NYMAIN01 Doc: 159158_2
                                       30

<PAGE>

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 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 this 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 Section 4.17 hereof. 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 Section 4.07. 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.

SECTION 4.08.   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
                SUBSIDIARIES.

           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 as in
effect on the date of this Indenture, (2) the Credit Agreement as in effect as
of the date of this 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 this Indenture, (3) this 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 this
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 capitalized lease
obligations otherwise permitted by clause (e) of Section 4.09 hereof, 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.

SECTION 4.09.   INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

           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 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, 


NYMAIN01 Doc: 159158_2
                                       32

<PAGE>

(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 this
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).

SECTION 4.10.   ASSET SALES.

           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 Section 4.14 hereof and/or the provisions of
Section 5.01 hereof, and not by the provisions of this Section 4.10), 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 forth in an Officers' Certificate
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


NYMAIN01 Doc: 159158_2
                                       33

<PAGE>

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 theconsideration
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 or a similar line of
business as the Company or any of its Restricted Subsidiaries was engaged in on
the date of this 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 this 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 this 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.

           An Asset Sale Offer shall be made pursuant to the provisions of
Section 3.09 hereof. No later than the date which is five Business Days after
the date on which the aggregate amount of Excess Proceeds exceeds $5 million,
the Company shall notify the Trustee of such Asset Sale Offer and provide the
Trustee with an Officers' Certificate setting forth the calculations used in
determining the amount of Net Proceeds to be applied to the purchase of
Securities. The Company shall commence or cause to be commenced the Asset Sale
Offer on a date no later than 15 Business Days after such notice (the
"Commencement Date").

SECTION 4.11.   TRANSACTIONS WITH AFFILIATES.

           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, 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


NYMAIN01 Doc: 159158_2
                                       34

<PAGE>

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 excessof $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 Section 4.07
hereof 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 Section 4.09
hereof.

SECTION 4.12.   LIENS.

           The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien (other than a Permitted Lien) upon any property or assets 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.

SECTION 4.13.   ADDITIONAL SUBSIDIARY GUARANTEES.

           If any entity (other than an Excluded Restricted Subsidiary) shall
become a Restricted Subsidiary after the date of this 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 this
Indenture.

           No Restricted Subsidiary shall 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 


NYMAIN01 Doc: 159158_2
                                       35

<PAGE>

its Subsidiary Guarantee, 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 byor 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 Section 4.09 hereof.

           In the event of (a) a sale or other disposition of all of the assets
of any Guarantor by way of merger, consolidation or otherwise, (b) a sale or
other disposition of all of the capital stock of any Guarantor, or (c) the
designation of a Guarantor as an Unrestricted Subsidiary in accordance with the
terms of Section 4.17, then such Guarantor (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 Guarantor, or in the event of the designation of such
Guarantor 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 Guarantor) shall 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 this
Indenture.

SECTION 4.14.   OFFER TO PURCHASE UPON 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

offer described below (the "Change of Control Offer") at an offer price in cash

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
      this Section 4.14 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. Prior to complying
with the provisions of this Section 4.14, but in any event within 90 calendar
days following a Change of Control, the Company shall either repay all
outstanding Senior Debt or obtain the requisite consents, if any, under all
agreements governing outstanding Senior Debt to permit the repurchase of Notes
required by this Section 4.14. The Company shall publicly announce in The Wall
Street Journal, or if no longer published, a national newspaper of general
circulation the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

SECTION 4.15.   CORPORATE EXISTENCE.

           Subject to Article 5 and Article 11 hereof, as the case may be, the
Company and each of the Restricted Subsidiaries shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate
existence, and the corporate, partnership or other existence of each of their
Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of the Company, any such Restricted
Subsidiary or any such Subsidiary, as the case may be, and (ii) the rights
(charter and statutory), licenses and franchises of the Company, the Restricted
Subsidiaries and their respective Subsidiaries; provided, however, that the
Company and the Restricted Subsidiaries shall not be required to preserve any

                                       37

<PAGE>

such right, license or franchise, or the corporate, partnership or other
existence of any of their respective Subsidiaries, if an officer of the Company
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company, the Restricted Subsidiaries and their
Subsidiaries, taken as a whole and that the loss thereof is not adverse in any
material respect to the Holders of the Notes.

SECTION 4.16.   CERTAIN SENIOR SUBORDINATED DEBT.

           Notwithstanding the provisions of Section 4.09 hereof, (a) the
Company shall 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 shall 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.

SECTION 4.17.   DESIGNATION OF 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 Section 4.07 hereof; (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 Section 4.07 hereof. Notwithstanding the
foregoing, the Company may not designate as an Unrestricted Subsidiary any
Subsidiary which, on the date of this 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 Section 4.09 hereof and
(ii) no Default or Event of Default would occur as a result of such designation.

SECTION 4.18    LIMITATION ON SALE AND LEASEBACK TRANSACTIONS

           The Company shall not, and shall 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, and (b) the Company or such Restricted Subsidiary could incur the
Attributable Indebtedness in respect of such Sale and Leaseback Transaction in
compliance with Section 4.09 hereof.

SECTION 5.01.   MERGER, CONSOLIDATION, OR SALE OF ASSETS.

           The Company shall 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 entity 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 this 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 first paragraph of Section 4.09 hereof.

SECTION 5.02.   SUCCESSOR CORPORATION SUBSTITUTED.

           Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company or the Company and its Subsidiaries on a consolidated basis in
accordance with Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided, however, that
the predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale of all of
the Company's assets that meets the requirements of Section 5.01 hereof.

                           CERTAIN DEFAULT PROVISIONS

SECTION 6.01.   EVENTS OF DEFAULT.

           An "Event of Default" occurs if:

                (a) the Company and the Guarantors default in the payment of
      interest on the Notes (whether or not prohibited by the subordination

      the same becomes due and payable and such default continues for a period
      of 30 days;

                (b) the Company and the Guarantors default in the payment of
      principal of or premium, if any, on the Notes (whether or not prohibited

      redemption (including in connection with an offer to purchase) or
      otherwise;

                (c)   the Company fails to comply with the provisions of 
      Section 4.14 hereof;

                (d) the Company or the Guarantors fail to comply with any of

      Notes, the Subsidiary Guarantees or this Indenture and the Default
      continues for the period and after the notice specified below;

                (e) a default occurs 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 now exists or shall be created hereafter 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
      such Indebtedness that has been accelerated or not paid at maturity,
      together with the principal amount of any other Indebtedness that has been
      accelerated or not paid at maturity, exceeds $5.0 million;

                (f) a final judgment or final judgments for the payment of money
      are entered by a court or courts of competent jurisdiction against the
      Company or any of its Restricted Subsidiaries and such judgments remain
      unpaid, undischarged or unstayed for a period of 60 days, provided that
      the aggregate of all such unpaid, undischarged or unstayed judgments
      exceeds $5.0 million;

                (g) except as otherwise permitted hereunder, any Subsidiary
      Guarantee issued by a Guarantor 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 Guarantor (or its successors or

      assigns), or any Person acting on behalf of any Guarantor (or its
      successors or assigns), shall deny or disaffirm its obligations in writing
      under its Subsidiary Guarantee;

                (h)   the Company or any of its Restricted Subsidiaries that is
      a Significant Subsidiary:

                      (i)  commences a voluntary case,

                      (ii) consents to the entry of an order for relief against
           it in an involuntary case,

                      (iii) consents to the appointment of a Custodian of it or
           for all or substantially all of its property,

                      (iv) makes a general assignment for the benefit of its 
           creditors, or

                      (v)  admits in writing its inability generally to pay its
           debts as the same become due, in each case, pursuant to or within 
           the meaning of any Bankruptcy Law; or

                (i) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                      (i)  is for relief against the Company or any Restricted 
           Subsidiary that is a Significant Subsidiary of the Company in an 
           involuntary case,

                      (ii) appoints a Custodian of the Company or any Restricted
           Subsidiary that is a Significant Subsidiary of the Company or for all
           or substantially all of the property of the Company or any Restricted
           Subsidiary that is a Significant Subsidiary of the Company, or

                      (iii)orders the liquidation of the Company or any 
           Restricted Subsidiary that is a Significant Subsidiary of the 
           Company, and such order or decree remains unstayed and in effect for
           60 consecutive days.

           A Default under clause (d) is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the then outstanding Notes notify the Company and the Trustee, of the Default
and the Company does not cure the Default within 60 days after receipt of the
notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a "Notice of Default."

           In the case of any Event of Default pursuant to the provisions of
this Section 6.01 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
Section 3.07 hereof,an equivalent premium shall also become and be immediately
due and payable to the extent permitted by law upon acceleration of the Notes as
provided below, anything in this Indenture or in the Notes to the contrary
notwithstanding. 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] pursuant to Section 3.07 hereof, then the premium
payable for purposes of this paragraph for each of the years beginning on ______
of the years set forth below shall be as set forth in the following table
expressed as a percentage of the amount that would otherwise be due but for the
provisions of this sentence, plus accrued interest, if any, to the date of
payment:

              Year                                      Percentage

              1996......................................    ___%
              1997......................................    ___%
              1998......................................    ___%
              1999......................................    ___%
              2000......................................    ___%
              2001......................................    ___%
              2002......................................    ___%
              2003......................................    ___%
              2004......................................    ___%

SECTION 6.02.   ACCELERATION.

           If an Event of Default (other than an Event of Default specified in
clauses (h)(i) through (h)(iv) and (i) of Section 6.01 hereof relating to the
Company or any Significant Subsidiary) occurs and is continuing, the Trustee by
notice to the Company, or the Holders of at least 25% in principal amount of the
then outstanding Notes by notice to the Company and the Trustee may declare the
unpaid principal of and any accrued interest on all the Notes to be due and
payable. Upon such declaration the principal and interest shall be due and
payable immediately (together with the premium referred to in Section 6.01
hereof, if applicable); 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 (1) the day which
is five Business Days after written notice of acceleration is received by the
Company and the Credit Agent, and (2) the date of acceleration of the
Indebtedness under the Credit Agreement. If an Event of Default specified in
clauses (h)(i) through (h)(iv) or (i) of Section 6.01 hereof relating to the
Company or any Significant Subsidiary occurs, such an amount shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder. 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
Section 6.01(e) hereof, the declaration of acceleration of the Notes shall be
automatically annulled if the holders of any Indebtedness described in Section
6.01(e) have rescinded the declaration of acceleration in respect of such
Indebtedness within 30 days of the date of such declaration and if (a) the


NYMAIN01 Doc: 159158_2
                                       42

<PAGE>

annulment of the acceleration of the Notes would not conflict with any judgment
or decree of a competent jurisdiction, and (b) 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.

SECTION 6.03.   OTHER REMEDIES.

           If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and interest on the Notes or to enforce the performance of any provision of
the Notes or this Indenture.

           The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04.   WAIVER OF PAST DEFAULTS.

           Holders of not less than 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 an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium, if any, or interest on, the Notes
(including in connection with an offer to purchase) (provided, however, that the
Holders of a majority in aggregate principal amount of the then outstanding
Notes may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration). Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

SECTION 6.05.   CONTROL BY MAJORITY.

           Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

SECTION 6.06.   LIMITATION ON SUITS.

           A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes if, and only if:


NYMAIN01 Doc: 159158_2
                                       43

<PAGE>

                (a) the Holder of a Note gives to the Trustee written notice of
      a continuing Event of Default or the Trustee receives such notice from the
      Company;

                (b) the Holders of at least 25% in principal amount of the then
      outstanding Notes make a written request to the Trustee to pursue the
      remedy;

                (c) such Holder of a Note or Holders of Notes offer and, if
      requested, provide to the Trustee indemnity satisfactory to the Trustee
      against any loss, liability or expense;

                (d) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer and, if requested, the
      provision of indemnity; and

                (e) during such 60-day period the Holders of a majority in
      principal amount of the then outstanding Notes do not give the Trustee a
      direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another
Holder of a Note or to obtain a preference or priority over another Holder of a
Note. Nothing contained in this Section 6.06 shall affect the right of a Holder
of a Note to sue for enforcement of any overdue payment thereon.

SECTION 6.07.   RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

           Subject to Articles 10 and 11 hereof, notwithstanding any other
provision of this Indenture, the right of any Holder of a Note to receive
payment of principal of, premium, if any, and interest on the Note, on or after
the respective due dates expressed in the Note (including in connection with a
Purchase Offer), or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the
consent of such Holder.

SECTION 6.08.   COLLECTION SUIT BY TRUSTEE.

           If an Event of Default specified in Section 6.01(a) or (b) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium, if any, and interest remaining unpaid on the
Notes and interest on overdue principal and, to the extent lawful, interest and
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

SECTION 6.09.   TRUSTEE MAY FILE PROOFS OF CLAIM.

           The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company

(or any other obligor upon the Notes, including the Guarantors), its creditors
or its property and shall be entitled and empowered to collect, receive and
distribute any money or other property payable or deliverable on any such claims
and any custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

SECTION 6.10.   PRIORITIES.

           If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

                First:  to the Trustee, its agents and attorneys for amounts
      due under Section 7.07 hereof, including payment of all compensation, 
      expense and liabilities incurred, and all advances made, by the Trustee 
      and the costs and expenses of collection;

                Second:  to the holders of Senior Debt of the Company or the 
      Restricted Subsidiaries, as the case may be, to the extent required by 
      Article 10 or Article 11 hereof, as applicable;

                Third:  to Holders of Notes for amounts due and unpaid on the 
      Notes for principal, premium, if any, and interest, ratably, without 
      preference or priority of any kind, according to the amounts due and 
      payable on the Notes for principal, premium, if any, and interest,
      respectively; and

                Fourth:  to the Company or to such party as a court of 
      competent jurisdiction shall direct.

           The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

SECTION 6.11.   UNDERTAKING FOR COSTS.

           In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a 
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in 
principal amount of the then outstanding Notes.


                                    ARTICLE 7
                                     TRUSTEE

SECTION 7.01.   DUTIES OF TRUSTEE.

           (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

           (b)  Except during the continuance of an Event of Default:

                (i) the duties of the Trustee shall be determined solely by the
      express provisions of this Indenture and the Trustee need perform only
      those duties that are specifically set forth in this Indenture and no
      others, and no implied covenants or obligations shall be read into this
      Indenture against the Trustee; and

                (ii) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee shall examine the certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture.

           (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                (i)   this paragraph does not limit the effect of paragraph (b)
      of this Section;

                (ii) the Trustee shall not be liable for any error of judgment
      made in good faith by a Responsible Officer, unless it is proved that the
      Trustee was negligent in ascertaining the pertinent facts; and


NYMAIN01 Doc: 159158_2
                                       46

<PAGE>

                (iii) the Trustee shall not be liable with respect to any action
      it takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05 hereof.

           (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section.

           (e)  No provision of this Indenture shall require the Trustee to 
expend or risk its own funds or incur any liability.  The Trustee shall be
under no obligation to exercise any of its rights and powers under this
Indenture at the request of any Holders, unless such Holder shall have offered
to the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

           (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

           (g) Except with respect to Sections 4.01 and 4.04 herein, the Trustee
shall have no duty to inquire as to the performance of the Company's covenants
in Article 4 hereof. In addition, the Trustee shall not be deemed to have
knowledge of any Default or Event of Default except (i) any Event of Default
occurring pursuant to Sections 6.01(a), 6.01(b), 4.01 and 4.04 herein or (ii)
any Default or Event of Default of which the Trustee shall have received written
notification or obtained actual knowledge.

SECTION 7.02.   RIGHTS OF TRUSTEE.

           (a) The Trustee may conclusively rely upon any document believed by
it to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

           (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

           (c) The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

           (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

           (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.


NYMAIN01 Doc: 159158_2
                                       47

<PAGE>

           (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that might be incurred by it in compliance with such request or direction.

SECTION 7.03.   INDIVIDUAL RIGHTS OF TRUSTEE.

           The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company, any
Restricted Subsidiary or any Affiliate of the Company or any Restricted
Subsidiary with the same rights it would have if it were not Trustee. However,
in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04.   TRUSTEE'S DISCLAIMER.

           The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

SECTION 7.05.   NOTICE OF DEFAULTS.

           If a Default or Event of Default occurs and is continuing and if it
is known to the Trustee, the Trustee shall mail to the Holders of the Notes a
notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal of,
premium, if any, or interest on any Note, the Trustee may withhold the notice if
and so long as a committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of the Holders of the Notes.

SECTION 7.06.   REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

           Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 313(c).

           A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Notes are listed in 


NYMAIN01 Doc: 159158_2
                                       48

<PAGE>

accordance with TIA ss. 313(d). The Company shall promptly notify the Trustee 
when the Notes are listed on any stock exchange.

SECTION 7.07.   COMPENSATION AND INDEMNITY.

           The Company and the Restricted Subsidiaries shall pay to the Trustee
from time to time reasonable compensation for its acceptance of this Indenture
and services hereunder. The Trustee's compensation shall not be limited by any
law on compensation of a trustee of an express trust. The Company and the
Restricted Subsidiaries shall reimburse the Trustee promptly upon request for
all reasonable disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

           The Company and the Restricted Subsidiaries shall indemnify the
Trustee against any and all losses, liabilities or expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company and the Restricted Subsidiaries (including this
Section 7.07), and defending itself against any claim (whether asserted by the
Company, any Restricted Subsidiary or any Holder or any other person) or
liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, liability or expense may
be attributable to its negligence or bad faith. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company and the
Restricted Subsidiaries of their obligations hereunder. The Company and the
Restricted Subsidiaries shall defend the claim and the Trustee shall cooperate
in the defense. The Trustee may have separate counsel and the Company and the
Restricted Subsidiaries shall pay the reasonable fees and expenses of such
counsel. The Company and the Restricted Subsidiaries need not pay for any
settlement made without their consent, which consent shall not be unreasonably
withheld.

           The obligations of the Company and the Restricted Subsidiaries under
this Section 7.07 shall survive the satisfaction and discharge of this
Indenture.

           To secure the Company's and the Restricted Subsidiaries' payment
obligations in this Section, the Trustee shall have a Lien prior to the Notes on
all money or property held or collected by the Trustee, except that held in
trust to pay principal and interest on particular Notes. Such Lien shall survive
the satisfaction and discharge of this Indenture.

           When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

           The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to
the extent applicable.

SECTION 7.08.   REPLACEMENT OF TRUSTEE.

           A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section.

           The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

                (a)   the Trustee fails to comply with Section 7.10 hereof;

                (b)   the Trustee is adjudged a bankrupt or an insolvent or an
      order for relief is entered with respect to the Trustee under any 
      Bankruptcy Law;

                (c)   a Custodian or public officer takes charge of the Trustee
      or its property; or

                (d)   the Trustee becomes incapable of acting.

           If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

           If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, any
Restricted Subsidiary, or the Holders of Notes of at least 10% in principal
amount of the then outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

           If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10 hereof, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

           A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Company's and the Restricted Subsidiaries' obligations
under Section 7.07 hereof shall continue for the benefit of the retiring
Trustee.

SECTION 7.09.   SUCCESSOR TRUSTEE BY MERGER, ETC.

           If the Trustee consolidates, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Trustee.

SECTION 7.10.   ELIGIBILITY; DISQUALIFICATION.

           There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50 million
as set forth in its most recent published annual report of condition.

           This Indenture shall always have a Trustee who satisfies the
requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA
ss. 310(b).

SECTION 7.11.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

           The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01.   OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

           The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article Eight.

SECTION 8.02.   LEGAL DEFEASANCE AND DISCHARGE.

           Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, each of the Company and the Guarantors, if any,
shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be deemed to have been discharged from its obligations with respect to
all outstanding Notes and Subsidiary Guarantees on the date the conditions set
forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose,
Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes, which
shall thereafter be deemed to be "outstanding" only for the purposes of Section
8.05 hereof and the other Sections of this Indenture referred to in (a) and (b)
below, and to have satisfied all its other obligations under such Notes 


NYMAIN01 Doc: 159158_2
                                       51

<PAGE>

and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 8.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest on such Notes when such payments are due, (b) the Company's
and Guarantors' obligations with respect to such Notes under Article 2 and
Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of
the Trustee hereunder and the Company's and the Guarantors' obligations in
connection therewith and (d) this Article Eight. Subject to compliance with this
Article Eight, the Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 hereof.

SECTION 8.03.   COVENANT DEFEASANCE.

           Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, each of the Company and the Guarantors, if any,
shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be released from its obligations under the covenants contained in
Sections 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17
and Article V hereof with respect to the outstanding Notes and Subsidiary
Guarantees on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed
not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.01 hereof, but, except as specified
above, the remainder of this Indenture, such Notes and the Subsidiary
Guarantees, if any, shall be unaffected thereby. In addition, upon the Company's
exercise under Section 8.01 hereof of the option applicable to this Section 8.03
hereof, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, Sections 6.01(c) through 6.01(f) and Section 6.01(h) and 6.01(i) hereof
shall not constitute Events of Default.

SECTION 8.04.   CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

      The following shall be the conditions to the application of either Section
8.02 or 8.03 hereof to the outstanding Notes:

           In order to exercise either Legal Defeasance or Covenant Defeasance:

      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 date for payment thereof 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 an election under Section 8.02 hereof, the
      Company shall have delivered to the Trustee an Opinion of Counsel in the
      United States (which counsel may be an employee of the Company or any
      Subsidiary of the Company) reasonably acceptable to the Trustee confirming
      that (A) the Company has received from, or there has been published by,
      the Internal Revenue Service a ruling or (B) since the Issuance Date,
      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 an election under Section 8.03 hereof, the
      Company shall have delivered to the Trustee an Opinion of Counsel in the
      United States (which counsel may be an employee of the Company or any
      Subsidiary of the Company) 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 Sections 6.01(h) and
      6.01(i) hereof are concerned, at any time in the period ending on the 91st
      day after the date of deposit (or greater period of time in which any such
      deposit of trust funds may remain subject to Bankruptcy Law insofar as
      those apply to the deposit by the Company);

                (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 (other than this Indenture) 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


NYMAIN01 Doc: 159158_2

      Notes over any 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 or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with.

SECTION 8.05.   DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST; 
                OTHER MISCELLANEOUS PROVISIONS.

           Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

           The Company and the Guarantors shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or
the principal and interest received in respect thereof other than any such tax,
fee or other charge which by law is for the account of the Holders of the
outstanding Notes.

           Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.06.   REPAYMENT TO COMPANY.

           Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium, if
any, or interest, if any, on any Note and remaining unclaimed for two years
after such principal, and premium, if any, or interest, if any, have become due
and payable shall be paid to the Company on its request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Note shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the

<PAGE>

Company cause to be published once, in The New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

SECTION 8.07.   REINSTATEMENT.

           If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Restricted Subsidiaries' obligations
under this Indenture, the Notes and the Subsidiary Guarantees shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.02 or
8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 8.02 or 8.03 hereof, as the case may
be; provided, however, that, if the Company and the Restricted Subsidiaries make
any payment of principal of, premium, if any, or interest, if any, on any Note
following the reinstatement of its obligations, the Company and the Restricted
Subsidiaries shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money held by the Trustee or Paying Agent.


                                    ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.   WITHOUT CONSENT OF HOLDERS OF NOTES.

           Notwithstanding Section 9.02 of this Indenture, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
without the consent of any Holder of a Note:

                (a)   to cure any ambiguity, defect or inconsistency;

                (b)   to provide for uncertificated Notes in addition to or in 
      place of certificated Notes;

                (c) to provide for the assumption of the Company's or any
      Guarantor's obligations to the Holders of the Notes in the case of a
      merger or consolidation pursuant to Article Five or Article 11 hereof, as
      the case may be;

                (d) to make any change that would provide any additional rights
      or benefits to the Holders of the Notes (including providing for
      additional Subsidiary Guarantees pursuant to Section 4.13 hereof) or that
      does not materially adversely affect the legal rights hereunder of any
      Holder of the Note; or


NYMAIN01 Doc: 159158_2
                                       55

<PAGE>

                (e) to comply with requirements of the SEC in order to effect or
      maintain the qualification of this Indenture under the TIA.

           Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company and the Guarantors in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02.   WITH CONSENT OF HOLDERS OF NOTES.

           Except as provided below in this Section 9.02, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
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 the Notes), and, subject to Sections 6.04 and
6.07 hereof, any existing Default or Event of Default (other than a Default or
Event of Default in the payment of the principal of, premium, if any, or
interest on the Notes, except a payment default resulting from an acceleration
that has been rescinded) or compliance with any provision of this 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 the Notes).

           Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence reasonably
satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid,
and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Company and the Guarantors in the
execution of such amended or supplemental Indenture unless such amended or
supplemental Indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such amended or
supplemental Indenture.

           It shall not be necessary for the consent of the Holders of Notes
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

           After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in 


NYMAIN01 Doc: 159158_2
                                       56

<PAGE>

a particular instance by the Company or any Guarantor with any provision of this
Indenture, the Note or the Subsidiary Guarantees. However, without the consent
of each Holder affected, an amendment or waiver may not (with respect to any
Notes held by a non-consenting Holder):

                (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 any of 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, including default 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 this 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 Section 4.10 or Section 4.14 hereof);

                (h) except pursuant to Article 4, Article 8 and Article 11
      hereof, release any Guarantor 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 Section 6.04 or 6.07 hereof or in the
      foregoing amendment and waiver provisions.

SECTION 9.03.   COMPLIANCE WITH TRUST INDENTURE ACT.

           Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.04.   REVOCATION AND EFFECT OF CONSENTS.

           Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation


NYMAIN01 Doc: 159158_2
                                       57

<PAGE>

of the consent is not made on any Note. However, any such Holder of a Note or
subsequent Holder of a Note may revoke the consent as to its Note if the Trustee
receives written notice of revocation before the date the waiver, supplement or
amendment becomes effective. An amendment, supplement or waiver becomes
effective in accordance with its terms and thereafter binds every Holder.

SECTION 9.05.   NOTATION ON OR EXCHANGE OF NOTES.

           The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall authenticate new Notes
(accompanied by a notation of the Subsidiary Guarantees duly endorsed by the
Restricted Subsidiaries) that reflect the amendment, supplement or waiver.

           Failure to make the appropriate notation or issue a new Note shall
not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06.   TRUSTEE TO SIGN AMENDMENTS, ETC.

           The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company and the Guarantors may not sign an amendment or supplemental
Indenture until the Board of Directors of the Company and each of the Guarantors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, an Officer's Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.


                                   ARTICLE 10
                                  SUBORDINATION

SECTION 10.01.  AGREEMENT TO SUBORDINATE.

           The Company, the Trustee and each Holder by accepting a Note agrees,
that the indebtedness and obligations evidenced by the Note are subordinated in
right of payment, to the extent and in the manner provided in this Article, to
the prior payment in full, in cash, of all Obligations with respect to Senior
Debt of the Company (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt of the Company.

SECTION 10.02.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.

           Upon any payment or distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar


NYMAIN01 Doc: 159158_2
                                       58

<PAGE>

proceeding relating to the Company or its property, in an assignment for the
benefit of creditors or any marshaling of the Company's assets and liabilities:

                (1) holders of Senior Debt of the Company shall be entitled to
      receive payment in full in cash of all Obligations due in respect of such
      Senior Debt of the Company (including interest after the commencement of
      any such proceeding at the rate specified in the applicable Senior Debt of
      the Company, whether or not allowed as a claim in such proceeding) before
      Holders shall be entitled to receive any payment or distribution from the
      Company with respect to the Notes; and

                (2) until all Obligations with respect to Senior Debt of the
      Company (as provided in subsection (1) above) are paid in full in cash,
      any payment or distribution to which the Trustee or any Holder would be
      entitled but for this Article shall be made to holders of Senior Debt of
      the Company, as their interests may appear.

SECTION 10.03.  DEFAULT ON DESIGNATED SENIOR DEBT.

           The Company may not 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:

                (i) a default in the payment of any principal, premium, if any,
      or interest or other Obligations (a "Payment Default") with respect to
      Senior Debt of the Company occurs and is continuing; or

                (ii) a default (other than a Payment Default) or any event that,
      after notice or passage of time would become a default (a "Non-Monetary
      Default"), on Senior Debt of the Company occurs and is continuing that
      then permits holders of the Senior Debt of the Company to accelerate its
      maturity and the Trustee receives a notice of the default (a "Payment
      Blockage Notice") from a Person who may give it pursuant to Section 10.11
      hereof. Any number of such Payment Blockage Notices may be given,
      provided, however, that (i) not more than one Payment Blockage Notice may
      be commenced during any period of 360 consecutive days and (ii) any
      Non-Monetary Default that existed or was continuing on the date of
      delivery of any such 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 days.

           The Company may and shall resume payments on and distributions in
respect of the Notes and all Obligations with respect thereto, and may acquire
such Notes or Obligations upon the earlier of:

                (1)   in the case of a Payment Default, the date upon which 
      such default is cured or waived, or


NYMAIN01 Doc: 159158_2
                                       59

<PAGE>

                (2) 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, if the maturity of such Senior Debt of the Company has not been
      accelerated,

if this Article 10 otherwise permits the payment, distribution or acquisition at
the time thereof.

SECTION 10.04.  ACCELERATION OF NOTES.

           If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify Representatives of the holders of
Senior Debt of the Company of the acceleration.

SECTION 10.05.  WHEN DISTRIBUTION MUST BE PAID OVER.

           In the event that the Trustee or any Holder receives from the Company
any payment of any Obligations with respect to the Notes at a time when the
Trustee or such Holder, as applicable, has actual knowledge that such payment is
prohibited by Section 10.02 or 10.03 hereof, such payment shall be held by the
Trustee or such Holder in trust for the benefit of, and shall be paid forthwith
over and delivered upon written request to, the holders of Senior Debt of the
Company, as their interests may appear, or their Representative under the
indenture or other agreement (if any) pursuant to which Senior Debt of the
Company may have been issued, as their respective interests may appear, for
application to the payment of all Obligations with respect to Senior Debt of the
Company remaining unpaid to the extent necessary to pay such Obligations in full
in accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt of the Company.

           With respect to the holders of Senior Debt of the Company, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article 10, and no implied covenants or
obligations with respect to the holders of Senior Debt of the Company shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of Senior Debt of the Company, and shall
not be liable to any such holders if the Trustee shall pay over or distribute to
or on behalf of Holders or the Company or any other Person money or assets to
which any holders of Senior Debt of the Company shall be entitled by virtue of
this Article 10, except if such payment is made as a result of the willful
misconduct or gross negligence of the Trustee.

SECTION 10.06.  NOTICE BY COMPANY.

           The Company shall promptly notify the Trustee and the Paying Agent of
any facts known to the Company that would cause a payment of any Obligations
with respect to the Notes to violate this Article, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt of the
Company as provided in this Article.


NYMAIN01 Doc: 159158_2
                                       60

<PAGE>

SECTION 10.07.  SUBROGATION.

           After all Obligations with respect to Senior Debt of the Company are
paid in full, in cash, and until the Notes are paid in full, Holders shall be
subrogated (equally and ratably with all other Indebtedness pari passu with the
Notes) to the rights of holders of Senior Debt of the Company to receive
distributions applicable to Senior Debt of the Company to the extent that
distributions otherwise payable to the Holders have been applied to the payment
of Senior Debt of the Company. A distribution made under this Article to holders
of Senior Debt of the Company that otherwise would have been made to Holders is
not, as between the Company and Holders, a payment by the Company on the Notes.

SECTION 10.08.  RELATIVE RIGHTS.

           This Article defines the relative rights of Holders and holders of
Senior Debt of the Company. Nothing in this Indenture shall:

                (1) impair, as between the Company and Holders, the obligation
      of the Company, which is absolute and unconditional, to pay principal of
      and interest on the Notes in accordance with their terms;

                (2) affect the relative rights of Holders and creditors of the
      Company other than their rights in relation to holders of Senior Debt of
      the Company; or

                (3) prevent the Trustee or any Holder from exercising its
      available remedies upon a Default or Event of Default, subject to the
      rights of holders and owners of Senior Debt of the Company to receive
      distributions and payments otherwise payable to Holders.

           If the Company fails because of this Article 10 to pay principal of,
premium or interest on a Note on the due date, the failure is still a Default or
Event of Default.

SECTION 10.09.  SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

           No right of any holder of Senior Debt of the Company to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any Holder to comply with this Indenture.

SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

           Whenever a distribution is to be made or a notice given to holders of
Senior Debt of the Company, the distribution may be made and the notice given to
their Representative.

           Upon any payment or distribution of assets of the Company referred to
in this Article 10, the Trustee and the Holders shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating


NYMAIN01 Doc: 159158_2
                                       61

<PAGE>

trustee or agent or other Person making any distribution to the Trustee or to
the Holders for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Debt of the Company and other
Indebtedness of the Company, the amount or amounts thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 10.

SECTION 10.11.  RIGHTS OF TRUSTEE AND PAYING AGENT.

           Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least one Business Day prior to the date of such
payment a Payment Blockage Notice. Only the holders or the Representative of
holders of Designated Senior Debt of the Company may give a Payment Blockage
Notice. Nothing in this Article 10 shall impair the claims of, or payments to,
the Trustee under or pursuant to Section 7.07 hereof.

           The Trustee in its individual or any other capacity may hold Senior
Debt of the Company with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.

SECTION 10.12.  AUTHORIZATION TO EFFECT SUBORDINATION.

           Each Holder of a Note by the Holder's acceptance thereof authorizes
and directs the Trustee on the Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as the Holder's attorney-in-fact for
any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section
6.09 hereof at least 30 days before the expiration of the time to file such
claim, the Representatives of the Senior Debt of the Company are hereby
authorized to file an appropriate claim for and on behalf of the Holders of the
Notes.

SECTION 10.13.  AMENDMENTS.

           The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of all Senior Debt of the Company.


                                   ARTICLE 11
                              SUBSIDIARY GUARANTEES

SECTION 11.01.  SUBSIDIARY GUARANTEE.

            Each Subsidiary that is a signatory hereto and each Restricted
Subsidiary of the Company which in accordance with Section 4.13 hereof is
required to guarantee the obligations of the


NYMAIN01 Doc: 159158_2
                                       62

<PAGE>

Company under the Notes (each, a "Guarantor"), upon execution of a counterpart
of this Indenture, hereby jointly and severally unconditionally guarantees to
each Holder of a Note authenticated and delivered by the Trustee irrespective of
the validity or enforceability of this Indenture, the Notes or the obligations
of the Company under this Indenture or the Notes, that: (i) the principal of and
interest on the Notes will be paid in full when due, whether at the maturity or
interest payment or mandatory redemption date, by acceleration, call for
redemption or otherwise, and interest on the overdue principal of and interest,
if any, on the Notes and all other obligations of the Company to the Holders or
the Trustee under this Indenture or the Notes will be promptly paid in full or
performed, all in accordance with the terms of this Indenture and the Notes; and
(ii) in case of any extension of time of payment or renewal of any Notes or any
of such other obligations, they will be paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at maturity, by
acceleration or otherwise. Failing payment when due of any amount so guaranteed
for whatever reason, each Guarantor will be obligated to pay the same whether or
not such failure to pay has become an Event of Default which could cause
acceleration pursuant to Section 6.02 hereof. Each Guarantor agrees that this is
a guarantee of payment not a guarantee of collection.

           Each Guarantor hereby agrees that its obligations with regard to this
Subsidiary Guarantee shall be joint and several, unconditional, irrespective of
the validity or enforceability of the Notes or the obligations of the Company
under this Indenture, the absence of any action to enforce the same, the
recovery of any judgment against the Company or any other obligor with respect
to this Indenture, the Notes or the obligations of the Company under this
Indenture or the Notes, any action to enforce the same or any other
circumstances (other than complete performance) which might otherwise constitute
a legal or equitable discharge or defense of a Guarantor. Each Guarantor
further, to the extent permitted by law, waives and relinquishes all claims,
rights and remedies accorded by applicable law to guarantors and agrees not to
assert or take advantage of any such claims, rights or remedies, including but
not limited to: (a) any right to require the Trustee, the Holders or the Company
(each, a "Benefitted Party") to proceed against the Company or any other Person
or to proceed against or exhaust any security held by a Benefitted Party at any
time or to pursue any other remedy in any Benefitted Party's power before
proceeding against such Guarantor; (b) the defense of the statute of limitations
in any action hereunder or in any action for the collection of any Indebtedness
or the performance of any obligation hereby guaranteed; (c) any defense that may
arise by reason of the incapacity, lack of authority, death or disability of any
other Person or the failure of a Benefitted Party to file or enforce a claim
against the estate (in administration, bankruptcy or any other proceeding) of
any other Person; (d) demand, protest and notice of any kind including but not
limited to notice of the existence, creation or incurring of any new or
additional Indebtedness or obligation or of any action or non-action on the part
of such Guarantor, the Company, any Benefitted Party, any creditor of such
Guarantor, the Company or on the part of any other Person whomsoever in
connection with any Indebtedness or obligations hereby guaranteed; (e) any
defense based upon an election of remedies by a Benefitted Party, including but
not limited to an election to proceed against such Guarantor for reimbursement;
(f) any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in other respects
more burdensome than that of the principal; (g) any defense arising because of a
Benefitted Party's election, in any proceeding instituted under Bankruptcy Law,
of the application of 11 U.S.C. Section 1111(b)(2); or (h) any defense based on

                                       63

<PAGE>

any borrowing or grant of a security interest under 11 U.S.C. Section 364. Each
Guarantor hereby covenants that its Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in its Subsidiary
Guarantee and this Indenture.

           If any Holder or the Trustee is required by any court or otherwise to
return to either the Company or any Guarantor, or any Custodian acting in
relation to either the Company or such Guarantor, any amount paid by the Company
or such Guarantor to the Trustee or such Holder, the applicable Subsidiary
Guarantees, to the extent theretofore discharged, shall be reinstated and be in
full force and effect. Each Guarantor agrees that it will not be entitled to any
right of subrogation in relation to the Holders in respect of any obligations
guaranteed hereby until payment in full of all obligations guaranteed hereby.

           Each Guarantor further agrees that, as between such Guarantor, on the
one hand, and the Holders and the Trustee, on the other hand, (i) the maturity
of the obligations guaranteed hereby may be accelerated as provided in Section
6.02 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any
stay, injunction or other prohibition preventing such acceleration as to the
Company or any other obligor on the Notes of the obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of those obligations as
provided in Section 6.02 hereof, those obligations (whether or not due and
payable) will forthwith become due and payable by such Guarantor for the purpose
of this Subsidiary Guarantee.

SECTION 11.02.  SUBORDINATION.

           Each Guarantor, the Trustee, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Subsidiary Guarantees is
subordinated in right of payment, to the extent and in the manner provided in
this Article 11, to the prior payment in full, in cash, of all Obligations with
respect to Senior Debt of such Guarantor (whether outstanding on the date hereof
or hereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the holders of Senior Debt of such
Guarantor.

SECTION 11.03.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.

           Upon any payment or distribution to creditors of any Guarantor in a
liquidation or dissolution of such Guarantor or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to such Guarantor or its
property, in an assignment for the benefit of creditors or any marshaling of
such Guarantor's assets and liabilities:

                (1) holders of Senior Debt of such Guarantor shall be entitled
      to receive payment in full in cash of all Obligations due in respect of
      such Senior Debt of such Guarantor (including interest after the
      commencement of any such proceeding at the rate specified in the
      applicable Senior Debt of such Guarantor, whether or not allowed as a
      claim in such proceeding) before the Holders shall be entitled to receive
      any payment or distribution from the Guarantor with respect to such
      Guarantor's Subsidiary Guarantee; and


NYMAIN01 Doc: 159158_2
                                       64

<PAGE>

                (2) until all Obligations with respect to Senior Debt of such
      Guarantor (as provided in subsection (1) above) are paid in full in cash,
      any payment or distribution to which the Trustee or any Holder would be
      entitled but for this Article shall be made to holders of Senior Debt of
      such Guarantor, as their interests may appear.

SECTION 11.04.  DEFAULT ON SENIOR DEBT OF THE GUARANTOR.

           No Guarantor shall make any payment or distribution upon or in
respect of the Notes or its Subsidiary Guarantee, 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:

                (i)   a Payment Default with respect to Senior Debt of such 
      Guarantor occurs and is continuing; or

                (ii) a Non-Monetary Default on Senior Debt of such Guarantor
      occurs and is continuing that then permits holders of the Senior Debt of
      such Guarantor to accelerate its maturity and the Trustee receives a
      Payment Blockage Notice from a Person who may give it pursuant to Section
      11.12 hereof. Any number of such Payment Blockage Notices may be given,
      provided, however, that (i) not more than one Payment Blockage Notice may
      be commenced during any period of 360 consecutive days and (ii) any
      default or event of 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 pursuant to Section 11.12 herein,
      unless such default has been cured or waived for a period of not less than
      90 consecutive days.

           Each Guarantor may and shall resume payments on and distributions in
respect of its Subsidiary Guarantee, the Notes and all Obligations with respect
thereto, and may acquire such Notes or Obligations upon the earlier of:

                (1)   in the case of a payment default, the date upon which 
      such default is cured or waived, or

                (2) 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, if the maturity of such Senior Debt of such Guarantor has not
      been accelerated,

if this Article 11 otherwise permits the payment, distribution or acquisition at
the time thereof.

SECTION 11.05.  ACCELERATION OF NOTES.

           If payment of the Notes is accelerated because of an Event of
Default, each Guarantor shall promptly notify the Representative of the holders
of Senior Debt of such Guarantor of the acceleration.

SECTION 11.06.  WHEN DISTRIBUTION MUST BE PAID OVER.

           In the event that the Trustee or any Holder receives from a Guarantor
any payment of any Obligations with respect to the Notes or the Subsidiary
Guarantees at a time when the Trustee or such Holder, as applicable, has actual
knowledge that such payment is prohibited by Section 11.03 or 11.04 hereof, such
payment shall be held by the Trustee or such Holder, in trust for the benefit
of, and shall be paid forthwith over and delivered upon written request to, the
holders of Senior Debt of such Guarantor, as their interests may appear, or
their Representative under the indenture or other agreement (if any) pursuant to
which Senior Debt of such Guarantor may have been issued, as their respective
interests may appear, for application to the payment of all Obligations with
respect to Senior Debt of such Guarantor remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Debt of such Guarantor.

           With respect to the holders of Senior Debt of any Guarantor, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Debt of such Guarantor shall
be read into this Indenture against the Trustee. The Trustee shall not be deemed
to owe any fiduciary duty to the holders of Senior Debt of such Guarantor, and
shall not be liable to any such holders if the Trustee shall pay over or
distribute to or on behalf of Holders or the Company or any other Person money
or assets to which any holders of Senior Debt of such Guarantor shall be
entitled by virtue of this Article 11, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

SECTION 11.07.  NOTICE BY A GUARANTOR.

           Each Guarantor shall promptly notify the Trustee and the Paying Agent
of any facts known to such Guarantor that would cause a payment of any
Obligations with respect to the Notes or its Subsidiary Guarantee to violate
this Article, but failure to give such notice shall not affect the subordination
of its Subsidiary Guarantee or of the Notes to the Senior Debt of such Guarantor
as provided in this Article.

SECTION 11.08.  SUBROGATION.

           With respect to any Guarantor, after all Obligations with respect to
Senior Debt of such Guarantor is paid in full, in cash, and until the Notes are
paid in full, Holders shall be subrogated (equally and ratably with all other
Indebtedness pari passu with such Guarantor's Subsidiary Guarantee) to the
rights of holders of Senior Debt of such Guarantor to receive distributions
applicable to Senior Debt of such Guarantor to the extent that distributions
otherwise payable to


NYMAIN01 Doc: 159158_2
                                       66

<PAGE>

the Holders have been applied to the payment of Senior Debt of such Guarantor. A
distribution made under this Article to holders of Senior Debt of such Guarantor
that otherwise would have been made to Holders is not, as between such Guarantor
and Holders, a payment by such Guarantor on the Notes or the Subsidiary
Guarantee.

SECTION 11.09.  RELATIVE RIGHTS.

           This Article defines the relative rights of Holders and holders of
Senior Debt of such Guarantor. Nothing in this Indenture shall:

                (1) impair, as between such Guarantor and the Holders, the
      obligation of such Guarantor, which is absolute and unconditional, to pay
      principal of and interest on the Notes in accordance with the terms of the
      Subsidiary Guarantee;

                (2) affect the relative rights of Holders and creditors of such
      Guarantor other than their rights in relation to holders of Senior Debt of
      such Guarantor; or

                (3) prevent the Trustee or any Holder from exercising its
      available remedies upon a Default or Event of Default, subject to the
      rights of holders of Senior Debt of such Guarantor set forth herein to
      receive distributions and payments otherwise payable to Holders.

           If any Guarantor fails because of this Article 11 to pay principal
of, premium or interest on a Note on the due date, the failure is still a
Default or Event of Default.

SECTION 11.10.  SUBORDINATION MAY NOT BE IMPAIRED BY ANY GUARANTOR.

           With respect to any Guarantor, no right of any holder of Senior Debt
of such Guarantor to enforce the subordination of the Indebtedness evidenced by
the Subsidiary Guarantee shall be impaired by any act or failure to act by such
Guarantor or any Holder or by failure of such Guarantor or any Holder to comply
with this Indenture.

SECTION 11.11.  DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

           With respect to any Guarantor, whenever a distribution is to be made
or a notice given to holders of Senior Debt of such Guarantor, the distribution
may be made and the notice given to their Representative.

           Upon any payment or distribution of assets of any Guarantor referred
to in this Article 11, the Trustee and the Holders shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders for the
purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt of such Guarantor and other
Indebtedness of such Guarantor, the amount or amounts thereof 


NYMAIN01 Doc: 159158_2
                                       67

<PAGE>

or payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this Article 11.

SECTION 11.12.  RIGHTS OF TRUSTEE AND PAYING AGENT.

           Notwithstanding the provisions of this Article 11 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least one Business Day prior to the date of such
payment a Payment Blockage Notice. Only the Representative of holders of
Designated Senior Debt may give a Payment Blockage Notice. Nothing in this
Article 11 shall impair the claims of, or payments to, the Trustee under or
pursuant to Section 7.07 hereof.

           With respect to any Guarantor, the Trustee in its individual or any
other capacity may hold Senior Debt of such Guarantor with the same rights it
would have if it were not Trustee. Any Agent may do the same with like rights.

SECTION 11.13.  AUTHORIZATION TO EFFECT SUBORDINATION.

           Each Holder of a Note by the Holder's acceptance thereof authorizes
and directs the Trustee on the Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 11, and appoints the Trustee to act as the Holder's attorney-in-fact for
any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding relative to any
Guarantor referred to in Section 6.09 hereof at least 30 days before the
expiration of the time to file such claim, the Representatives of Senior Debt of
such Guarantor are hereby authorized to file an appropriate claim for and on
behalf of the Holders of the Notes.

SECTION 11.14.  AMENDMENTS.

           With respect to any Guarantor, the provisions of Section 11.02
through 11.14 hereof shall not be amended or modified without the written
consent of the holders of all Senior Debt of such Guarantor.

SECTION 11.15.  LIMITATION OF GUARANTOR'S LIABILITY.

           Each Guarantor and, by its acceptance hereof, the Trustee and each
Holder hereby confirm that it is its intention that the Subsidiary Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Subsidiary Guarantee. To effectuate the foregoing intention,
each such person hereby irrevocably agrees that the obligation of such Guarantor
under its Subsidiary Guarantee under this Article 11 shall be limited to the
maximum amount as will, after giving effect to such maximum amount and all other
(contingent or other) liabilities of such Guarantor that are relevant


NYMAIN01 Doc: 159158_2
                                       68

<PAGE>

under such laws, and after giving effect to any collections from, rights to
receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under this
Article 11, result in the obligations of such Guarantor in respect of such
maximum amount not constituting a fraudulent transfer or conveyance under said
laws. The Trustee and each Holder by accepting the benefits hereof, confirms its
intention that, in the event of a bankruptcy, reorganization or other similar
proceeding of the Company or any Guarantor in which concurrent claims are made
upon such Guarantor hereunder, to the extent such claims will not be fully
satisfied, each such claimant with a valid claim against the Company shall be
entitled to a ratable share of all payments by such Guarantor in respect of such
concurrent claims. For all purposes of this Section 11.15, Senior Debt shall be
deemed to have been incurred prior to the incurrence of the obligations in
respect of the Subsidiary Gaurantees.

SECTION 11.16.  RESTRICTED SUBSIDIARIES MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

           No Guarantor shall consolidate with or merge with or into (whether or
not such Guarantor is the surviving Person), another Person whether or not it is
affiliated with such Guarantor unless (i) subject to the provisions of Section
11.17 hereof, the Person formed by or surviving any such consolidation or merger
(if other than such Guarantor) assumes all the obligations of such Guarantor
pursuant to a supplemental indenture in form reasonably satisfactory to the
Trustee, under its Subsidiary Guarantee, the Notes and this Indenture, (ii)
immediately after giving effect to such transaction, no Default or Event of
Default exists, and (iii) such Guarantor, or any Person formed by or surviving
any such consolidation or merger, will be permitted to incur, immediately after
giving effect to such transaction, at least $1.00 of additional Indebtedness
pursuant to the first paragraph of Section 4.09 hereof. In case of any such
consolidation, merger, sale or conveyance and upon the assumption by the
successor corporation, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee in
this Indenture and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Guarantor,
such successor corporation shall succeed to and be substituted for the Guarantor
with the same effect as if it had been named herein as a Guarantor.

SECTION 11.17.  RELEASES FOLLOWING SALE OF ASSETS OR DESIGNATION AS 
UNRESTRICTED SUBSIDIARY.

           In the event of (a) a sale or other disposition of all or
substantially all of the assets of any Guarantor, by way of merger,
consolidation or otherwise, or (b) a sale or other disposition of all of the
capital stock of any Guarantor, or (c) the designation of a Restricted
Subsidiary as an Unrestricted Subsidiary in accordance with the terms of Section
4.17 hereof, then such Guarantor (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 Guarantor, or in the event of the designation of such Guarantor as an
Unrestricted Subsidiary) or the corporation acquiring the property (in the event
of a sale or other disposition of all or substantially all of the assets of such
Guarantor) shall be released and relieved of its obligations under its
Subsidiary Guarantee; provided that the Net Proceeds of such sale or other
disposition are applied in accordance with Section 4.10 hereof.

                                 (Back of Note)

                          __% SENIOR SUBORDINATED NOTE
                                    DUE 2006

                  Capitalized terms used herein have the meanings assigned to
them in the Indenture (as defined below) unless otherwise indicated.

                  1. Interest. Iron Mountain Incorporated, a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at the rate and in the manner specified below.

                  The Company shall pay in cash interest on the principal amount
of this Note at the rate per annum of __%. The Company will pay interest
semi-annually in arrears on ________ and ________ of each year, commencing on
________, 1997 or if any such day is not a Business Day (as defined in the
Indenture), on the next succeeding Business Day (each an "Interest Payment
Date"), to Holders of record on the immediately preceding ________ and
_________.

                  Interest will be computed on the basis of a 360-day year
consisting of twelve 30-day months. Interest shall accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of the original issuance of the Notes. To the extent lawful, the Company
shall pay interest on overdue principal at the rate of 1% per annum in excess of
the then applicable interest rate on the Notes; it shall pay interest on overdue
installments of interest (without regard to any applicable grace periods) at the
same rate to the extent lawful.

                  2. Method of Payment. The Company will pay interest on the
Notes (except defaulted interest) to the Persons who are registered Holders of
Notes at the close of business on the record date next preceding the Interest
Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. The Company, however, may pay principal,
premium, if any, and interest by check payable in such money. It may mail an
interest check to a Holder's registered address.

                  3.       Paying Agent and Registrar.  Initially, the Trustee
will act as Paying Agent and Registrar. The Company may change any Paying Agent,
Registrar or co-registrar without notice to any Holder. The Company or any
Restricted Subsidiary may act in any such capacity.

                  4. Indenture. The Company issued the Notes under an Indenture
dated as of ________, 1996 (the "Indenture") between the Company, the Restricted
Subsidiaries named therein and 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 (15 U.S. Code ss.ss. 77aaa-77bbbb) as in effect on
the date of the Indenture. The Notes are subject to all such terms, and Holders
of

the Notes are referred to the Indenture and such act for a statement of such
terms. The terms of the Indenture shall govern any inconsistencies between the
Indenture and the Notes. The Notes are unsecured general obligations of the
Company limited to $___,000,000 in aggregate principal amount.

                  5. Optional Redemption. The Company shall not have the option
to redeem the Notes pursuant to Section 3.07 of the Indenture prior to
_________, 2001. Thereafter, the Company shall have the option to redeem the
Notes, in whole or in part, upon not less than 30 nor more than 60 days' notice,
at the redemption prices (expressed as percentages of the principal amount) set
forth below, plus accrued and unpaid interest thereon to the applicable
redemption date, if redeemed during the 12 month period beginning on ________ 15
of the years indicated below:

          Year                                                     Percentage

          2001.....................................................  ___.__%
          2002.....................................................  ___.__%
          2003.....................................................  ___.__%
          2004 and thereafter......................................  100.00%

                  Notwithstanding the foregoing, at any time prior to ________,
1999, 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 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.

                  6. Mandatory Redemption. Except as described in paragraph 7
below, the Company shall not be required to make sinking fund or redemption
payments with respect to the Notes.

                  7. Redemption or Repurchase at Option of Holder.  This Note 
is subject to purchase at the option of the Holder upon the circumstances set 
forth in Section 3.09 and 4.14 of the Indenture.

                  8. Notice of Redemption. Notice of redemption shall be mailed
at least 30 days but not more than 60 days before the redemption date to each
Holder of Notes to be redeemed at its registered address. Notes may be redeemed
in part but only in whole multiples of $1,000, unless all of the Notes held by a
Holder are to be redeemed. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.

                  9. Subordination.  The Notes are subordinated to Senior Debt 
(as defined in the Indenture) (whether outstanding on the date of the Indenture
 or thereafter created, incurred,

                                       A-3

assumed or guaranteed) and all Obligations (as defined in the Indenture) with
respect thereto. To the extent provided in the Indenture, Senior Debt must be
paid in full in cash before the Notes may be paid. The Company agrees, and each
Holder by accepting a Note agrees, to the subordination and authorizes the
Trustee to give it effect.

                  10. Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not exchange or register the transfer of any
Note or portion of a Note selected for redemption. Also, it need not exchange or
register the transfer of any Notes for a period of 15 days before a selection of
Notes to be redeemed, or during the period between a record date and the
corresponding Interest Payment Date.

                  11. Persons Deemed Owners. Prior to due presentment to the
Trustee for registration of the transfer of this Note, the Trustee, any Agent,
the Company and the Guarantors may deem and treat the Person in whose name this
Note is registered as its absolute owner for the purpose of receiving payment of
principal of, premium, if any, and interest on this Note and for all other
purposes whatsoever, whether or not this Note is overdue, and none of the
Trustee, any Agent, the Company or any Guarantor shall be affected by notice to
the contrary. The registered holder of a Note shall be treated as its owner for
all purposes.

                  12. Amendments and Waivers. Subject to certain exceptions, the
Indenture or the Notes may be amended with the consent of the Holders of at
least a majority in principal amount of the then outstanding Notes (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 any Holder, the Indenture or the Notes may be amended to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to provide for assumption of the
Company's or any Restricted Subsidiary's obligations to Holders in the case of a
merger or consolidation or to make any change that would provide any additional
rights or benefits to the Holders or that does not adversely affect the rights
of any Holder under the Indenture or to comply with the requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act.

                  13. Defaults and Remedies. Events of Default include: default

25% of the aggregate principal amount of the Notes outstanding to comply with
any of its other agreements in the Indenture or the Notes; 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 now exists, or is created after the date of the
Indenture, if (a) 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 (b) the principal
amount of such Indebtedness that has been accelerated or not paid at maturity,
together with the principal amount of any other Indebtedness that has been
accelerated or not paid at maturity, exceeds $5.0 million; failure by the
Company or any of its 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; except as permitted by the Indenture, 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 its obligations
under its Subsidiary Guarantees; and certain events of bankruptcy or insolvency
with respect to the Company or any of its Subsidiaries. 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, except that in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, relating to the Company
or any Significant Subsidiary, all outstanding Notes will become due and payable
without further action or notice; 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 (1) the day which
is five Business Days after written notice of acceleration is received by the
Company and the Credit Agent, and (2) the date of acceleration of the
Indebtedness under the Credit Agreement. Holders of the Notes may not enforce
the Indenture or the Notes except as provided in the Indenture. 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 must furnish an annual compliance certificate
to the Trustee.

                  14. Subsidiary Guarantees. Payment of principal of, premium,
if any, and interest (including interest on overdue principal, premium, if any,
and interest, if lawful) on the Notes is guaranteed on an unsecured, senior 
subordinated basis by the Guarantors pursuant to Article 11 of the Indenture.

                  15. Trustee Dealings with Company. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company, any Restricted Subsidiary
or their respective Affiliates, and may otherwise deal with the Company, any
Restricted Subsidiary or their respective Affiliates, as if it were not Trustee.

Company or any Restricted Subsidiary 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

                  19. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and has directed the Trustee to
use CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Notes or as contained in any notice of redemption and reliance may be placed
only on the other identification numbers placed thereon.

________________, between __________________ (the "Restricted Subsidiary"), a
subsidiary of Iron Mountain Incorporated (or its successor), a Delaware
corporation (the "Company"), and ______________________________, a national

"Trustee").

                               W I T N E S S E T H

           WHEREAS, Iron Mountain Incorporated, a Delaware corporation has
heretofore executed and delivered to the Trustee an indenture (the "Indenture"),
dated as of ________, 1996, providing for the issuance of an aggregate principal
amount of $___,000,000 of __% Senior Subordinated Notes due 2006 (the "Notes");

           WHEREAS, Section 4.13 of the Indenture provides that under certain
circumstances the Company is required to cause the Restricted Subsidiary to
execute and deliver to the Trustee a supplemental indenture pursuant to which
the Restricted Subsidiary shall unconditionally guarantee all of the Company's
obligations under the Notes pursuant to a Subsidiary Guarantee on the terms and
conditions set forth herein; and

           WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

           NOW THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Restricted Subsidiary and the Trustee mutually covenant and agree for the equal
and ratable benefit of the Holders of the Notes as follows:

      1. CAPITALIZED TERMS. Capitalized terms used herein without definition 
shall have the meanings assigned to them in the Indenture.

      2. AGREEMENT TO GUARANTEE. The Restricted Subsidiary hereby agrees that
its obligations to the Holder and the Trustee pursuant to this Subsidiary
Guarantee shall be as expressly set forth in Article 11 of the Indenture and in
such other provisions of the Indenture as are applicable to Restricted
Subsidiaries, and reference is made to the Indenture for the precise terms of
this Supplemental Indenture. The terms of Article 11 of the Indenture and such
other provisions of the Indenture as are applicable to Restricted Subsidiaries

      of such Restricted Subsidiary on each Note authenticated and delivered by
      the Trustee after the date hereof.

           (b) Notwithstanding the foregoing, the Restricted Subsidiary hereby
      agrees that its Subsidiary Guarantee set forth herein shall remain in full
      force and effect notwithstanding any failure to endorse on each Note a
      notation of such Subsidiary Guarantee.

           (c) If an Officer whose signature is on this Supplemental Indenture
      or on the Subsidiary Guarantee no longer holds that office at the time the
      Trustee authenticates the Note on which a Subsidiary Guarantee is
      endorsed, the Subsidiary Guarantee shall be valid nevertheless.

           (d) The delivery of any Note by the Trustee, after the authentication
      thereof under the Indenture, shall constitute due delivery of the
      Subsidiary Guarantee set forth in this Supplemental Indenture on behalf of
      the Restricted Subsidiary.

      4. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder of the Restricted Subsidiary, as

Restricted Subsidiary under the Notes, any Subsidiary Guarantee, the Indenture
or this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes.

                  FORM OF NOTATION ON SENIOR SUBORDINATED NOTE
                        RELATING TO SUBSIDIARY GUARANTEE

           Each Guarantor set forth below and each Restricted Subsidiary of the

guarantee the obligations of the Company under the Notes, upon execution of a
counterpart of the Indenture, jointly and severally unconditionally guarantees
(i) the due and punctual payment of the principal of and interest on the Notes,

Company to the Holders or the Trustee under the Indenture or the Notes and (ii)
in case of any extension of time of payment or renewal of any Notes or any of
such other obligations, that the same will be promptly paid in full when due or

           The obligations of each Guarantor to the Holder and to the Trustee
pursuant to this Subsidiary Guarantee and the Indenture are as expressly set

Indenture as are applicable to Guarantors, and reference is hereby made to such

      Re:   Registration Statement on Form S-1
            $150,000,000 of Senior Subordinated Notes due 2006

Ladies and Gentlemen:

      The following opinion is furnished to you in connection with the
registration pursuant to a registration statement on Form S-1 (File No.
333-10359) (the "Registration Statement") under the Securities Act of 1933, as
amended (the "Securities Act"), by Iron Mountain Incorporated, a Delaware
corporation (the "Company"), of $150,000,000 of Senior Subordinated Notes due
2006 (the "Notes"), which Notes will initally be guaranteed (the "Guarantees")
by each of the Company's direct and indirect wholly owned subsidiaries
(collectively, the "Subsidiary Guarantors") and issued under an indenture
relating to the Notes (the "Indenture") by and among the Company, the Subsidiary
Guarantors and First Bank National Association, as Trustee (the "Trustee").

      We have acted as counsel to the Company in connection with the preparation
of the Registration Statement, and we have examined originals or copies,
certified or otherwise identified to our satisfaction, of corporate records,
certificates and statements of officers and accountants of the Company, of
public officials, and such other documents as we have considered necessary in
order to furnish the opinion hereinafter set forth. We express no opinion herein
as to any laws other than the General Corporation Law of the State of Delaware
and the Laws of the Commonwealth of Massachusetts and the State of New York.
Insofar as the opinions herein pertain to matters of California law relating to
Hollywood Property, Inc., a California corporation and a Subsidiary Guarantor
("HPI"), we have with your consent relied upon the opinion of Nossaman, Guthner,
Knox & Elliott, California counsel to HPI.

      Based upon and subject to the foregoing, we are of the opinion that the
Company and the Subsidiary Guarantors have taken all necessary action to approve
the Indenture and the terms of the Notes and Guarantees, and when (i) the
Registration Statement has become effective under the Securities Act, (ii) the
Indenture has been duly executed and delivered by the Company, the Subsidiary
Guarantors and the Trustee and the Notes have been duly executed by the Company
and authenticated by the Trustee and the Guarantees have been duly executed by
the Subsidiary Guarantors in accordance with the provisions of the Indenture,
(iii) the Indenture has been qualified under the Trust Indenture Act of 1939, as
amended, and (iv) the Notes with the Guarantees affixed thereto have been
delivered to the purchasers thereof against payment of the purchase price
therefor as described in the Registration Statement, the Notes and the
Guarantees will be validly issued and binding obligations of the Company and the
Subsidiary Guarantors, respectively, subject in each case to the effect of (a)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights and remedies of creditors and the
obligations of debtors generally and (b) the application of general principles
of equity (regardless of whether enforcement is considered in proceedings at law
or in equity).

      We express no opinion as to the applicability (and, if applicable, the
effect) of Section 548 of the United States Bankruptcy Code or any comparable
provision of state law to the conclusions expressed above.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm made therein under the
caption "Validity of Securities." In giving such consent, we do not thereby
admit that we come within the category of persons whose consent is required
under Section 7 of the Securities Act or the Rules and Regulations of the
Securities and Exchange Commission promulgated thereunder.

                                          Very truly yours,

                        -----------------------------------------
failure of any Lender to make any Loan to be made by it on the
date specified therefor shall not relieve any other Lender of its
obligation to make its Loan on such date, but neither the
Administrative Agent nor any Lender shall be responsible for the
failure of any other Lender to make a Loan to be made by such
other Lender.  The amounts payable by the Company at any time
hereunder and under the Notes to each Lender shall be a separate
and independent debt and each Lender shall be entitled to protect
and enforce its rights arising out of this Agreement and the

Company to endorse on the schedule (or a continuation thereof) attached to each
Note of such Lender, to the extent applicable, the date, amount and Type of and
the Interest Period (if any) for each Loan made by such Lender to the Company
hereunder, and the date and amount of each payment or prepayment of principal of
such Loan received by such Lender, provided that any failure by such Lender to
make any such endorsement shall not affect the obligations of the Company under
such Note or hereunder in respect of such Loan.

                  2.07 Use of Proceeds. The proceeds of the Loans shall be used
for the general corporate purposes of the Company and its Subsidiaries,
including, without limitation, the making of Permitted Acquisitions and the

this Agreement, the Commitments may be utilized, upon the request of the
Company, in addition to the Loans provided for by Section 2.01 hereof, by the

beyond the Commitment Termination Date). On the Closing Date, all Existing
Letters of Credit shall automatically, without any action on the part of any
Person, be deemed to be Letters of Credit issued and outstanding hereunder.

         Credit (including the beneficiary thereof) and the nature of the
         transactions or obligations proposed to be supported thereby (including
         whether such Letter of Credit is to be a commercial letter of credit or

         Agreement in an amount equal to such Lender's Commitment Percentage of
         the then undrawn face amount of such Letter of Credit. Each Lender
         (other than the Issuing Bank) agrees that, upon the issuance of any
         Letter of Credit hereunder, it shall automatically acquire a
         participation in the Issuing Bank's liability under such Letter of
         Credit in an amount equal to such Lender's Commitment Percentage of
         such liability, and each Lender (other than the Issuing Bank) thereby
         shall automatically absolutely, unconditionally and irrevocably assume,
         as primary obligor and not as surety, and be unconditionally obligated
         to the Issuing Bank to pay and discharge when due, its Commitment
         Percentage of the Issuing Bank's liability under such Letter of Credit.

                  (c) Upon receipt from the beneficiary of any Letter of Credit
         of any demand for payment under such Letter of Credit, the Issuing Bank
         shall promptly notify the Company (through the Administrative Agent) of
         the amount to be paid by the Issuing Bank as a result of such demand
         and the date on which payment is to be made by the Issuing Bank to such
         beneficiary in respect of such demand. Notwithstanding the identity of
         the account party of any Letter of Credit, the Company hereby
         unconditionally agrees to pay and reimburse the Administrative Agent
         for account of the Issuing Bank for the amount of each demand for
         payment under such Letter of Credit that is in substantial compliance
         with the provisions of such Letter of Credit at or prior to the date on
         which payment is to be made by the Issuing Bank to the beneficiary

         thereunder, without presentment, demand, protest or other
         formalities of any kind.

                  (d) Forthwith upon its receipt of a notice referred to in
         paragraph (c) of this Section 2.08, the Company shall advise the
         Administrative Agent whether or not the Company intends to borrow
         hereunder to finance its obligation to reimburse the Issuing Bank for
         the amount of the related demand for payment and, if it does, submit a
         notice of such borrowing as provided in Section 4.05 hereof.

                  (e) Each Lender (other than the Issuing Bank) shall pay to the
         Administrative Agent for account of the Issuing Bank at an account in
         New York, New York specified by the Administrative Agent in Dollars and
         in immediately available funds the amount of such Lender's Commitment
         Percentage of any payment under a Letter of Credit upon notice by the
         Issuing Bank (through the Administrative Agent) to such Lender
         requesting such payment and specifying such amount. Each such Lender's
         obligation to make such payment to the Administrative Agent for account
         of the Issuing Bank under this paragraph (e), and the Issuing Bank's
         right to receive the same, shall be absolute and unconditional and
         shall not be affected by any circumstance whatsoever, including,
         without limitation, the failure of any other Lender to make its payment
         under this paragraph (e), the financial condition of the Company (or
         any other account party), any failure to satisfy any condition
         precedent to any Loan, the existence of any Default or the termination
         of the Commitments. Each such payment to the Issuing Bank shall be made
         without any offset, abatement, withholding or reduction whatsoever. If
         any Lender shall default in its obligation to make any such payment to
         the Administrative Agent for account of the Issuing Bank, for so long
         as such default shall continue the Administrative Agent may at the
         request of the Issuing Bank withhold from any payments received by the
         Administrative Agent under this Agreement or any Note for account of
         such Lender the amount so in default and, to the extent so withheld,
         pay the same to the Issuing Bank in satisfaction of such defaulted
         obligation.

                  (f) Upon the making of each payment by a Lender to the Issuing
         Bank pursuant to paragraph (e) above in respect of any Letter of
         Credit, such Lender shall, automatically and without any further action
         on the part of the Administrative Agent, the Issuing Bank or such
         Lender, acquire (i) a participation in an amount equal to such payment
         in the Reimbursement Obligation owing to the Issuing Bank by the
         Company hereunder and under the Letter of Credit Documents relating to
         such Letter of Credit and (ii) a participation in a percentage equal to
         such Lender's Commitment Percentage


                                Credit Agreement

         in any interest or other amounts payable by the Company hereunder and
         under such Letter of Credit Documents in respect of such Reimbursement
         Obligation (other than the commissions, charges, costs and expenses
         payable to the Issuing Bank pursuant to paragraph (g) of this Section
         2.08). Upon receipt by the Issuing Bank from or for account of the
         Company of any payment in respect of any Reimbursement Obligation or
         any such interest or other amount (including by way of setoff or
         application of proceeds of any collateral security) the Issuing Bank
         shall promptly pay to the Administrative Agent for account of each
         Lender entitled thereto such Lender's Commitment Percentage of such
         payment, each such payment by the Issuing Bank to be made in the same
         money and funds in which received by the Issuing Bank. In the event any
         payment received by the Issuing Bank and so paid to the Lenders
         hereunder is rescinded or must otherwise be returned by the Issuing
         Bank, each Lender shall, upon the request of the Issuing Bank (through
         the Administrative Agent), repay to the Issuing Bank (through the
         Administrative Agent) the amount of such payment paid to such Lender,
         with interest at the rate specified in paragraph (j) of this Section
         2.08.

                  (g) The Company shall pay to the Administrative Agent for
         account of each Lender (ratably in accordance with their respective
         Commitment Percentages) a letter of credit fee in respect of each
         Letter of Credit in an amount equal to the Applicable L/C Percentage of
         the daily average undrawn face amount of such Letter of Credit for the
         period from and including the date of issuance of such Letter of Credit
         (i) in the case of a Letter of Credit that expires in accordance with
         its terms, to and including such expiration date and (ii) in the case
         of a Letter of Credit that is drawn in full or is otherwise terminated
         other than on the stated expiration date of such Letter of Credit, to
         but excluding the date such Letter of Credit is drawn in full or is
         terminated (such fee to be non-refundable, to be paid in arrears on
         each Quarterly Date and on the Commitment Termination Date and on the
         date of expiry or termination or full utilization of such Letter of
         Credit and to be calculated for any day after giving effect to any
         payments made under such Letter of Credit on such day). In addition,
         the Company shall pay to the Administrative Agent for account of the
         Issuing Bank a fronting fee in respect of each Letter of Credit in an
         amount equal to 0.25% per annum of the daily average undrawn face
         amount of such Letter of Credit for the period from and including the
         date of issuance of such Letter of Credit (i) in the case of a Letter
         of Credit that expires in accordance with its terms, to and including
         such expiration date and (ii) in the case of a Letter of Credit that is
         drawn in full or is otherwise

         terminated other than on the stated expiration date of such Letter of
         Credit, to but excluding the date such Letter of Credit is drawn in
         full or is terminated (such fee to be non-refundable, to be paid in
         arrears on each Quarterly Date and on the Commitment Termination Date
         and to be calculated for any day after giving effect to any payments
         made under such Letter of Credit on such day) plus all commissions,
         charges, costs and expenses in the amounts customarily charged by the
         Issuing Bank from time to time in like circumstances with respect to
         the issuance of each Letter of Credit and drawings and other
         transactions relating thereto.

                  (h) Promptly following the end of each calendar month, the
         Issuing Bank shall deliver (through the Administrative Agent) to each
         Lender and the Company a notice describing the aggregate amount of all
         Letters of Credit outstanding at the end of such month. Upon the
         request of any Lender from time to time, the Issuing Bank shall deliver
         any other information reasonably requested by such Lender with respect
         to each Letter of Credit then outstanding.

                  (i) The issuance by the Issuing Bank of each Letter of Credit
         shall, in addition to the conditions precedent set forth in Section 7
         hereof, be subject to the conditions precedent that (i) such Letter of
         Credit shall be in such form, contain such terms and support such
         transactions as shall be satisfactory to the Issuing Bank consistent
         with its then current practices and procedures with respect to letters
         of credit of the same type and (ii) the Company shall have executed and
         delivered such applications, agreements and other instruments relating
         to such Letter of Credit as the Issuing Bank shall have reasonably
         requested consistent with its then current practices and procedures
         with respect to letters of credit of the same type, provided that in
         the event of any conflict between any such application, agreement or
         other instrument and the provisions of this Agreement or any Security
         Document, the provisions of this Agreement and the Security Documents
         shall control.

                  (j) To the extent that any Lender shall fail to pay any amount
         required to be paid pursuant to paragraph (e) or (f) of this Section
         2.08 on the due date therefor, such Lender shall pay interest to the
         Issuing Bank (through the Administrative Agent) on such amount from and
         including such due date to but excluding the date such payment is made
         at a rate per annum equal to the Federal Funds Effective Rate, provided
         that if such Lender shall fail to make such payment to the Issuing Bank
         within three Business Days of such due date, then, retroactively to the
         due date, such Lender shall

<PAGE>


                                     - 31 -


         be obligated to pay interest on such amount at the
         Post-Default Rate.

                  (k) The issuance by the Issuing Bank of any modification or
         supplement to any Letter of Credit hereunder shall be subject to the
         same conditions as are applicable under this Section 2.08 to the
         issuance of new Letters of Credit, and no such modification or
         supplement shall be issued hereunder unless either (i) the respective
         Letter of Credit affected thereby would have complied with such
         conditions had it originally been issued hereunder in such modified or
         supplemented form or (ii) each Lender shall have consented thereto.

The Company hereby indemnifies and holds harmless each Lender (including the
Issuing Bank) and the Administrative Agent from and against any and all claims
and damages, losses, liabilities, costs or expenses that such Lender or the
Administrative Agent may incur (or that may be claimed against such Lender or
the Administrative Agent by any Person whatsoever) by reason of or in connection
with the execution and delivery or transfer of or payment or refusal to pay by
the Issuing Bank under any Letter of Credit; provided that the Company shall not
be required to indemnify any Lender or the Administrative Agent for any claims,
damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by (x) the willful misconduct or gross negligence of the Issuing
Bank in determining whether a request presented under any Letter of Credit
complied with the terms of such Letter of Credit or (y) in the case of the
Issuing Bank, such Lender's failure to pay under any Letter of Credit after the
presentation to it of a request strictly complying with the terms and conditions
of such Letter of Credit. Nothing in this Section 2.08 is intended to limit the
other obligations of the Company, any Lender or the Administrative Agent under
this Agreement.

                  Section 3.  Borrowings, Conversions and Prepayments.

                  3.01 Borrowings. The Company shall give the Administrative
Agent notice of each Loan to be made hereunder as provided in Section 5.05
hereof. Not later than 11:00 a.m. New York time on the date specified for each
such borrowing hereunder, each Lender shall make available the amount of the
Loan to be made by it on such date to the Administrative Agent, at an account in
New York, New York specified by the Administrative Agent, in immediately
available funds, for account of the Company. The amount so received by the
Administrative Agent shall, subject to the terms and conditions of this
Agreement, be made available to the Company by depositing the same, in
immediately available funds, in an account of the

                  3.02  Prepayments and Conversions.

                  (a) Optional Prepayments and Conversions. The Company shall
have the right to prepay Loans and to convert Loans of one Type into Loans of
the other Type, at any time or from time to time, provided that: (i) the Company
shall give the Administrative Agent notice of each such prepayment as provided
in Section 5.05 hereof and (ii) except to the extent required pursuant to
Section 3.02(b) hereof, Eurodollar Loans may be prepaid or converted only on the
last day of an Interest Period for such Loans.

                  (b)  Mandatory Prepayments.

                  (1) Casualty Events; Condemnation Awards. On the date twelve
         months following the receipt by the Company or any of its Subsidiaries
         of any proceeds of insurance, condemnation award or other compensation
         in respect of any Casualty Event affecting any property of the Company
         or any of its Subsidiaries (or upon such earlier date as the Company or
         such Subsidiary, as the case may be, shall have determined not to
         repair or replace the property affected by such Casualty Event), the
         Company shall prepay the Loans (and/or provide cover for Letter of
         Credit Liabilities as specified in paragraph (c) below), and the
         Commitments shall be subject to automatic reduction, in an aggregate
         amount, if any, equal to 100% of the Net Cash Proceeds of such Casualty
         Event not theretofore applied to the repair or replacement of such
         property.

                  (2) Issuance of Indebtedness. The Company shall prepay the
         Loans (and/or provide cover for Letter of Credit Liabilities as
         specified in paragraph (c) below) in the amount of and on the date of
         each receipt by the Company or any Subsidiary of the Company of Net
         Cash Proceeds from issuance subsequent to the Closing Date of
         Indebtedness other than Indebtedness incurred pursuant to Section 9.08
         (it being understood that this Section 3.02(b)(2) shall not constitute
         a waiver of any provision of Section 9.08).

                  (3) Asset Dispositions. During each fiscal year of the
         Company, the Company shall prepay the Loans (and/or provide cover for
         Letter of Credit Liabilities as specified in paragraph (c) below), in
         an amount equal to the excess of (a) the sum of (x) the Net Cash
         Proceeds received by the Company or any Subsidiary of the Company from
         any disposition by such Person of any assets during such fiscal year,
         other than a disposition permitted by clause (i) or


                                Credit Agreement

                                     - 33 -


         (ii) of Section 9.12 plus (y) any payments with respect to receivables
         retained by such Person arising from the sale of goods or services at
         facilities disposed of in asset dispositions during such fiscal year
         over (b) $1,000,000. Such prepayments shall be made from time to time
         on the first Business Day that the excess amount referred to above
         (less all amounts previously applied to the prepayment of the Loans
         pursuant to this paragraph (3) during such fiscal year) is $100,000 or
         more.

Any prepayment pursuant to paragraphs (1) through (3) above shall automatically
reduce the Commitments in an amount equal to the amount specified in such
paragraphs (and to the extent that, after giving effect to such reduction, the
aggregate principal amount of Loans and the aggregate amount of Letter of Credit
Liabilities would exceed the Commitments, the Company shall, first, prepay Loans
and, second, provide cover for Letter of Credit Liabilities as specified in
paragraph (c) below, in an aggregate amount equal to such excess). The Company
shall notify the Administrative Agent promptly upon the occurrence of any event
giving rise to a prepayment or Commitment reduction under this Section 3.02(b).

                  (c) Cover for Letter of Credit Liabilities. In the event that
the Loans have been repaid in full, amounts payable under Section 3.02(b) shall
be applied to provide cash cover for outstanding Letters of Credit, in which
event the Company shall effect the same by paying to the Administrative Agent
immediately available funds in an amount equal to the required amount, which
funds shall be retained by the Administrative Agent in the Collateral Account as
collateral security in the first instance for the Letter of Credit Liabilities
until such time as the Letters of Credit shall have been terminated and all of
the Letter of Credit Liabilities paid in full.

                  Section 4.  Payments of Principal and Interest.

                  4.01 Repayment of Loans. The Company hereby promises to pay to
the Administrative Agent for account of each Lender the entire outstanding
principal amount of such Lender's Loans, and each Loan shall mature, on the
Commitment Termination Date.

                  4.02 Interest. The Company will pay to the Administrative
Agent for the account of each Lender interest on the unpaid principal amount of
each Loan made by such Lender for the period commencing on the date of such Loan
to but excluding the date such Loan shall be paid in full, at the following
rates per annum:

                  (a)  if such Loan is an ABR Loan, the Alternate Base
         Rate plus the Applicable Margin; and


                                Credit Agreement

<PAGE>


                                     - 34 -



                  (b)  if such Loan is a Eurodollar Loan, the Eurodollar
         Rate plus the Applicable Margin.

Notwithstanding the foregoing, the Company hereby promises to pay to the
Administrative Agent for account of each Lender interest at the applicable
Post-Default Rate

                  (x) on any principal of any Loan made by such Lender, on any
         Reimbursement Obligation held by such Lender and on any other amount
         payable by the Company hereunder or under the Note held by such Lender
         to or for account of such Lender (but, if such amount is interest, only
         to the extent legally enforceable), that shall not be paid in full when
         due (whether at stated maturity, by acceleration, by mandatory
         prepayment or otherwise), for the period from and including the due
         date thereof to but excluding the date the same is paid in full and

                  (y) on any principal of any Loan made by such Lender during
         any period when an Event of Default shall have occurred under Section
         10.01(a) hereof and for so long as such Event of Default shall be
         continuing.

Accrued interest on each Loan shall be payable (i) if such Loan is an ABR Loan,
on each Quarterly Date, (ii) if such Loan is a Eurodollar Loan, on the last day
of each Interest Period for such Loan (and, if such Interest Period exceeds
three months' duration, quarterly, commencing on the first quarterly anniversary
of the first day of such Interest Period), and (iii) in any event, upon the
payment, prepayment or conversion thereof, but only on the principal so paid or
prepaid or converted; provided that interest payable at the Post-Default Rate
shall be payable from time to time on demand of the Administrative Agent or the
Majority Lenders. Promptly after the determination of any interest rate provided
for herein or any change therein, the Administrative Agent shall notify the
Lenders and the Company thereof.

                  Notwithstanding the foregoing provisions of this Section 4.02,
if at any time the rate of interest set forth above on any Loan of any Lender
(the "Stated Rate" for such Loan) exceeds the maximum non-usurious interest rate
permissible for such Lender to charge commercial borrowers under applicable law
(the "Maximum Rate" for such Lender), the rate of interest charged on such Loan
of such Lender hereunder shall be limited to the Maximum Rate for such Lender.

                  In the event the Stated Rate for any Loan of a Lender that has
theretofore been subject to the preceding paragraph at any time is less than the
Maximum Rate for such Lender, the principal amount of such Loan shall bear
interest at the Maximum


                                Credit Agreement

<PAGE>


                                     - 35 -


Rate for such Lender until the total amount of interest paid to such Lender or
accrued on its Loans hereunder equals the amount of interest which would have
been paid to such Lender or accrued on such Lender's Loans hereunder if the
Stated Rate had at all times been in effect.

                  In the event, upon payment in full of all amounts payable
hereunder, the total amount of interest paid to any Lender or accrued on such
Lender's Loans under the terms of this Agreement is less than the total amount
of interest which would have been paid to such Lender or accrued on such
Lender's Loans if the Stated Rate had, at all times, been in effect, then the
Company shall, to the extent permitted by applicable law, pay to the
Administrative Agent for the account of such Lender an amount equal to the
difference between (a) the lesser of (i) the amount of interest which would have
accrued on such Lender's Loans if the Maximum Rate for such Lender had at all
times been in effect or (ii) the amount of interest which would have accrued on
such Lender's Loans if the Stated Rate had at all times been in effect and (b)
the amount of interest actually paid to such Lender or accrued on its Loans
under this Agreement.

                  In the event any Lender ever receives, collects or applies as
interest any sum in excess of the Maximum Rate for such Lender, such excess
amount shall be applied to the reduction of the principal balance of its Loans
or to other amounts (other than interest) payable hereunder, and if no such
principal is then outstanding, such excess or part thereof remaining shall be
paid to the Company.

                  Section 5.  Payments; Pro Rata Treatment; Computations;
Etc.

                  5.01 Payments. Except to the extent otherwise provided herein,
all payments of principal, interest, Reimbursement Obligations and other amounts
to be made by the Company hereunder and under the Notes shall be made in
Dollars, in immediately available funds, to the Administrative Agent at an
account in New York, New York specified by the Administrative Agent, not later
than 11:00 a.m. New York time on the date on which such payment shall become due
(each such payment made after such time on such due date to be deemed to have
been made on the next succeeding Business Day). The Administrative Agent, or any
Lender for whose account any such payment is made, may (but shall not be
obligated to) debit the amount of any such payment which is not made by such
time to any ordinary deposit account of the Company with the Administrative
Agent or such Lender, as the case may be. The Company shall, at the time of
making each payment hereunder or under any Note, specify to the Administrative
Agent the Loans or other amounts payable by the Company hereunder to which such
payment is to be applied (and in the event that it


                                Credit Agreement

<PAGE>


                                     - 36 -


fails to so specify, or if an Event of Default has occurred and is continuing,
the Administrative Agent may apply such payment for the benefit of the Lenders
as it may elect in its sole discretion, but subject to the other terms and
conditions of this Agreement, including without limitation, Section 5.02
hereof). Each payment received by the Administrative Agent hereunder or under
any Note for the account of a Lender shall be paid promptly to such Lender, in
immediately available funds, for the account of such Lender's Applicable Lending
Office. If the due date of any payment hereunder or under any Note would
otherwise fall on a day which is not a Business Day such date shall be extended
to the next succeeding Business Day and interest shall be payable for any
principal so extended for the period of such extension.

                  5.02 Pro Rata Treatment. Except to the extent otherwise
provided herein: (a) each borrowing from the Lenders under Section 2.01 hereof
shall be made from the Lenders, each payment of commitment fees under Section
2.03 hereof shall be made for the account of the Lenders, and each termination
or reduction of the Commitments under Section 2.02 hereof shall be applied to
the Commitments of the Lenders, pro rata according to the Lenders' respective
percentages of the Commitments, (b) each payment by the Company of principal of
or interest on Loans of a particular Type (other than payments in respect of
Loans of individual Lenders provided for by Section 6 hereof) shall be made to
the Administrative Agent for the account of the Lenders pro rata in accordance
with the respective unpaid principal amounts of such Loans held by the Lenders
and (c) each conversion of Loans of a particular Type (other than conversions of
Loans of individual Lenders pursuant to Section 6.04 hereof) shall be made pro
rata among the Lenders in accordance with the respective principal amounts of
such Loans held by the Lenders.

                  5.03 Computations. Interest and fees shall be computed on the
basis of a year of 360 days (or 365 or 366 days, as the case may be, in the case
of ABR Loans the interest rate payable on which is then based on the Prime Rate)
and actual days elapsed (including the first day but excluding the last day)
occurring in the period for which payable.

                  5.04 Minimum and Maximum Amounts; Types. Except for
prepayments made pursuant to Section 3.02(b) hereof, each borrowing, conversion
and prepayment of principal of Loans shall be in an aggregate principal amount
equal to (a) in the case of Eurodollar Loans, $1,000,000 or a larger multiple of
$100,000, and (b) in the case of ABR Loans, $500,000 or a larger multiple of
$100,000 (borrowings, conversions or prepayments of Loans of different Types or,
in the case of Eurodollar Loans, having different Interest Periods, at the same
time hereunder to be deemed separate borrowings, conversions and prepayments for
purposes of the foregoing, one for Type or Interest Period);

provided that (i) any Loan may be in the aggregate amount of the unused portion
of the relevant Commitments, (ii) Loans may be prepaid in full and (ii) any
borrowing or prepayment of Loans that are ABR Loans may be in an aggregate
principal amount equal to $100,000 or a larger multiple of $100,000.

                  5.05 Certain Notices. Notices to the Administrative Agent of
terminations or reductions of Commitments, of borrowings, conversions and
prepayments of Loans and of the duration of Interest Periods shall be
irrevocable and shall be effective only if received by the Administrative Agent
not later than 1:00 p.m. New York time on the number of Business Days prior to
the date of the relevant termination, reduction, borrowing, conversion and/or
prepayment specified below:

                                                             Number of

         Borrowing or prepayment of
         ABR Loans                                                    1

         Borrowing or prepayment of,
         conversion of or into, or
         duration of Interest Period
         for, Eurodollar Loans                                        3

         Prepayments required pursuant
         to Section 3.02(b)                                           1

Each such notice of termination or reduction shall specify the amount thereof to
be terminated or reduced. Each such notice of borrowing, conversion or
prepayment shall specify the amount and Type of the Loans to be borrowed,
converted or prepaid (subject to Sections 3.02(a) and 5.04 hereof), the date of
borrowing, conversion or prepayment (which shall be a Business Day) and, in the
case of Eurodollar Loans, the duration of the Interest Period therefor (subject
to the definition of Interest Period). Each such notice of duration of an
Interest Period shall specify the Loans to which such Interest Period is to
relate. The Administrative Agent shall promptly notify the affected Lenders of
the contents of each such notice. In the event that the Company fails to select
the duration of any Interest Period for any Eurodollar Loans within the time
period and otherwise as provided in this Section 5.05, such Loans (if
outstanding as Eurodollar Loans) will be automatically converted into ABR Loans
on the last day of the then current Interest Period for such


                                Credit Agreement

<PAGE>


                                     - 38 -


Loans or (if outstanding as ABR Loans) will remain as, or (if not then
outstanding) will be made as, ABR Loans.

                  5.06 Non-Receipt of Funds by the Administrative Agent. Unless
the Administrative Agent shall have been notified by a Lender or the Company
(the "Payor") prior to the date on which such Lender is to make payment to the
Administrative Agent of the proceeds of a Loan to be made by it hereunder or the
Company is to make a payment to the Administrative Agent for the account of one
or more of the Lenders, as the case may be (such payment being herein called the
"Required Payment"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Administrative Agent,
the Administrative Agent may assume that the Required Payment has been made and
may, in reliance upon such assumption (but shall not be required to), make the
amount thereof available to the intended recipient on such date and, if the
Payor has not in fact made the Required Payment to the Administrative Agent, the
recipient of such payment shall, on demand, pay to the Administrative Agent the
amount made available to it together with interest thereon in respect of the
period commencing on the date such amount was so made available by the
Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Effective Rate for such
period.

                  5.07 Sharing of Payments; Waiver of Enforcement Without
Consent, Etc. (a) The Company agrees that, in addition to (and without
limitation of) any right of set-off, banker's lien or counterclaim a Lender may
otherwise have, each Lender shall be entitled, at its option, to offset balances
held by it for the account of the Company at any of its offices, in Dollars or
in any other currency, against any principal of or interest on any of such
Lender's Loans or Reimbursement Obligations to the Company hereunder, or any
other obligation of the Company hereunder, which is not paid when due
(regardless of whether such balances are then due to the Company), in which case
it shall promptly notify the Company and the Administrative Agent thereof,
provided that such Lender's failure to give such notice shall not affect the
validity thereof. The Company agrees, to the fullest extent it may effectively
do so under applicable law, that any Person purchasing a participation in the
Loans made, or other obligations held, by another Person, whether or not
acquired pursuant to the foregoing arrangements, may exercise all rights of
set-off, banker's lien, counterclaim or similar rights with respect to such
participation as fully as if such Lender were a direct holder of Loans or other
obligations in the amount of such participation.

                  (b)  If a Lender shall obtain payment of any principal
of or interest on any Loan made by it under this Agreement, or on


                                Credit Agreement

<PAGE>


                                     - 39 -


any other obligation then due to such Lender hereunder, through the exercise of
any right of set-off, banker's lien, counterclaim or similar right, or
otherwise, it shall promptly notify the Administrative Agent and purchase from
the other Lenders participations in the Loans made, or other obligations held,
by the other Lenders in such amounts, and make such other adjustments from time
to time as shall be equitable to the end that all the Lenders shall share the
benefit of such payment (net of any expenses which may be incurred by such
Lender in obtaining or preserving such benefit) pro rata in accordance with the
unpaid principal and interest on the Loans or other obligations then due to each
of them. To such end all the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored (including the payment of interest to
the extent that the Lender obligated to return such funds is obligated to return
interest).

                  (c) Nothing contained herein shall require any Lender to
exercise any right of set-off, banker's lien, counterclaim or similar right or
shall affect the right of any Lender to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of the Company.

                  (d) This Section 5.07 is for the benefit of the Lenders only
and does not constitute a waiver of any rights against the Company or any of its
Subsidiaries or against any property held as security for any obligations
hereunder or under any other Basic Document.

                  5.08 Withholding Tax Exemption. At least five Business Days
prior to the first date on which interest or fees are payable hereunder for the
account of any Lender, each Lender that is not incorporated under the laws of
the United States of America or a state thereof agrees that it will deliver to
each of the Company and the Administrative Agent two duly completed copies of
United States Internal Revenue Service Form 1001 or 4224, certifying in either
case that such Lender is entitled to receive payments under this Agreement and
the Notes without deduction or withholding of any United States federal income
taxes. Each Lender which so delivers a Form 1001 or 4224 further undertakes to
deliver to each of the Company and the Administrative Agent two additional
copies of such form (or a successor form) on or before the date that such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form so delivered by it, and such amendments thereto
or extensions or renewals thereof as may be reasonably requested by the Company
or the Administrative Agent, in each case certifying that such Lender is
entitled to receive payments under this Agreement and the Notes without
deduction or


                                Credit Agreement

<PAGE>


                                     - 40 -


withholding of any United States federal income taxes, unless an event
(including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Lender from duly completing and delivering any such form with respect to it and
such Lender advises the Company and the Administrative Agent that it is not
capable of receiving payments without any deduction or withholding of United
States federal income tax.

                  Section 6.  Yield Protection and Illegality.

                  6.01  Additional Costs.

                  (a) The Company shall pay to the Administrative Agent for the
account of each Lender from time to time such amounts as such Lender may
determine to be necessary to compensate it for any costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurodollar Loans hereunder or its obligation to make any of such Loans
hereunder, or any reduction in any amount receivable by such Lender in respect
of any of such Loans or such obligation (such increases in costs and reductions
in amounts receivable being herein called "Additional Costs"), in each case
resulting from any Regulatory Change which:

                (i) changes the basis of taxation of any amounts payable to such
         Lender under this Agreement or its Notes in respect of any of such
         Loans (other than changes which affect taxes measured by or imposed on
         the overall net income of such Lender or of its Applicable Lending
         Office for any of such Loans by the jurisdiction in which such Lender
         has its principal office or such Applicable Lending Office); or

               (ii) imposes or modifies any reserve, special deposit or similar
         requirements relating to any extensions of credit or other assets of,
         or any deposits with or other liabilities of, such Lender (including
         any of such Loans or any deposits referred to in the definition of
         "Eurodollar Base Rate" in Section 1.01 hereof); or

              (iii) imposes any other condition affecting this Agreement (or any
         of such extensions of credit or liabilities).

Each Lender will notify the Company through the Administrative Agent of any
event occurring after the date of this Agreement which will entitle such Lender
to compensation pursuant to this Section 6.01(a) as promptly as practicable
after it obtains knowledge thereof and determines to request such compensation,
and (if so requested by the Company through the Administrative Agent) will
designate a different Applicable Lending Office for


                                Credit Agreement

<PAGE>


                                     - 41 -


the Eurodollar Loans of such Lender if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the sole opinion of
such Lender, be disadvantageous to such Lender (provided that such Lender shall
have no obligation to so designate an Applicable Lending Office located in the
United States of America). Each Lender will furnish the Company with a statement
setting forth the basis and amount of each request by such Lender for
compensation under this Section 6.01(a). If any Lender requests compensation
from the Company under this Section 6.01(a), the Company may, by notice to such
Lender through the Administrative Agent, suspend the obligation of such Lender
to make additional Eurodollar Loans to the Company until the Regulatory Change
giving rise to such request ceases to be in effect (in which case the provisions
of Section 6.04 hereof shall be applicable).

                  (b) Without limiting the effect of the foregoing provisions of
this Section 6.01, in the event that, by reason of any Regulatory Change, any
Lender either (i) incurs Additional Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of such Lender which includes deposits by reference to which the
interest rate on Eurodollar Loans is determined as provided in this Agreement or
a category of extensions of credit or other assets of such Lender which includes
Eurodollar Loans or (ii) becomes subject to restrictions on the amount of such a
category of liabilities or assets which it may hold, then, if such Lender so
elects by notice to the Company (with a copy to the Administrative Agent), the
obligation of such Lender to make Eurodollar Loans hereunder shall be suspended
until the date such Regulatory Change ceases to be in effect (in which case the
provisions of Section 6.04 hereof shall be applicable).

                  (c) Determinations and allocations by any Lender for purposes
of this Section 6.01 of the effect of any Regulatory Change on its costs of
maintaining its obligations to make Loans or of making or maintaining Loans or
on amounts receivable by it in respect of Loans, and of the additional amounts
required to compensate such Lender in respect of any Additional Costs, shall be
conclusive absent manifest error, provided that such determinations and
allocations are made on a reasonable basis.

                  (d) If any Lender demands compensation under this Section, the
Company may, at any time upon at least three (3) Business Days' prior notice to
such Lender through the Administrative Agent, convert in full the then
outstanding Eurodollar Loans of such Lender (in which case the Company shall be
obligated, if such conversion is made on a day that is not the last day of the
then current Interest Period applicable to such affected Eurodollar Loan, to
reimburse such Lender, in accordance


                                Credit Agreement

<PAGE>


                                     - 42 -


with Section 6.05, for any resulting loss or expense incurred by
it) to an ABR Loan.

                  6.02  Limitation on Types of Loans.  Anything herein to
the contrary notwithstanding, if, with respect to any Eurodollar
Loans:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive) that quotations of interest rates for the relevant
         deposits referred to in the definition of "Eurodollar Base Rate" in
         Section 1.01 hereof are not being provided by the Reference Lenders in
         the relevant amounts or for the relevant maturities for purposes of
         determining the rate of interest for such Loans for Interest Periods
         therefor as provided in this Agreement; or

                  (b) the Majority Lenders determine (which determination shall
         be conclusive) and notify the Administrative Agent that the relevant
         rates of interest referred to in the definition of "Eurodollar Base
         Rate" in Section 1.01 thereof upon the basis of which the rates of
         interest for such Loans are to be determined do not accurately reflect
         the cost to such Lenders of making or maintaining such Loans for
         Interest Periods therefor;

then the Administrative Agent shall promptly notify the Company and each Lender
thereof, and so long as such condition remains in effect, the Lenders shall be
under no obligation to make Eurodollar Loans or to convert ABR Loans into
Eurodollar Loans and the Company shall, on the last day(s) of the then current
Interest Period(s) for the outstanding Eurodollar Loans, either prepay such
Loans or convert such Loans into ABR Loans in accordance with Section 3.02
hereof.

                  6.03 Illegality. Notwithstanding any other provision of this
Agreement to the contrary, in the event that it becomes unlawful for any Lender
or its Applicable Lending Office to (a) honor its obligation to make Eurodollar
Loans hereunder, or (b) maintain Eurodollar Loans hereunder, then such Lender
shall promptly notify the Company thereof through the Administrative Agent and
such Lender's obligation to make Eurodollar Loans hereunder shall be suspended
until such time as such Lender may again make and maintain Eurodollar Loans (in
which case the provisions of Section 6.04 hereof shall be applicable).

                  6.04 Substitute ABR Loans. If the obligation of any Lender to
make Eurodollar Loans shall be suspended pursuant to Section 6.01, 6.02 or 6.03
hereof, all Loans which would otherwise be made by such Lender as Eurodollar
Loans shall be made instead as ABR Loans (and, if an event referred to in
Section 6.01(b) or 6.03 hereof has occurred and such Lender so


                                Credit Agreement

<PAGE>


                                     - 43 -


requests by notice to the Company with a copy to the Administrative Agent, each
Eurodollar Loan of such Lender then outstanding shall be automatically converted
into an ABR Loan on the date specified by such Lender in such notice) and, to
the extent that Eurodollar Loans are so made as (or converted into) ABR Loans,
all payments of principal which would otherwise be applied to such Eurodollar
Loans shall be applied instead to such ABR Loans.

                  6.05 Compensation. The Company shall pay to the Administrative
Agent for the account of each Lender, upon the request of such Lender through
the Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense incurred by it as a result of:

                  (a) any payment, prepayment or conversion of a Eurodollar Loan
         made by such Lender on a date other than the last day of an Interest
         Period for such Loan; or

                  (b) any failure by the Company to borrow a Eurodollar Loan to
         be made by such Lender on the date for such borrowing specified in the
         relevant notice of borrowing under Section 5.05 hereof

but excluding, in any event, loss of margin for the period after any such
payment, prepayment or conversion or failure to borrow; provided that such
Lender shall have delivered to the Company a certificate as to the amount of
such loss and expense along with the basis for calculation thereof.

                  6.06  Capital Adequacy.  If any Lender shall determine
that the adoption or implementation of any applicable law, rule,
regulation or treaty regarding capital adequacy, or any change
therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof,
or compliance by any Lender (or its Applicable Lending Office)
with any request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of
reducing the rate of return on capital of such Lender or any
Person controlling such Lender (a "Parent") as a consequence of
its obligations hereunder to a level below that which such Lender
(or its Parent) could have achieved but for such adoption, change
or compliance (taking into consideration its policies with
respect to capital adequacy) by an amount deemed by such Lender
to be material, then from time to time, within 15 days after
demand by such Lender (with a copy to the Administrative Agent),
the Company shall pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction.  A


                                Credit Agreement

<PAGE>


                                     - 44 -


statement of any Lender claiming compensation under this Section and setting
forth the additional amount or amounts to be paid to it hereunder shall be
conclusive absent manifest error; provided that the determination thereof is
made on a reasonable basis; and provided further that the Company shall not be
obligated to compensate such Lender for any such reduction occurring more than
180 days prior to the time such Lender first notifies the Company of such
adoption, implementation, change or compliance. In determining such amount, such
Lender may use any reasonable averaging and attribution methods.

                  6.07 Substitution of Lender. If (i) the obligation of any
Lender to make Eurodollar Loans or the right of the Company to convert ABR Loans
of any Lender to Eurodollar Loans has been suspended pursuant to Section 6.03,
or (ii) any Lender has demanded compensation under Section 6.01 or 6.06, the
Company shall have the right, with the assistance of the Administrative Agent,
to seek a substitute bank or banks (which may be one or more of the Lenders)
satisfactory to the Company and the Administrative Agent to purchase the Notes
and assume the Commitments of such Lender. Any such Lender shall be obligated to
sell the Notes for cash without recourse to such substitute bank or banks and to
execute and deliver an appropriately completed assignment and assumption
agreement reasonably satisfactory to the Administrative Agent and the Company
and any other document or perform any act reasonably necessary to effect the
assumption of the rights and obligations of such substitute bank or banks.

                  6.08 Additional Costs in Respect of Letters of Credit. Without
limiting the obligations of the Company under Section 6.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement heretofore or hereafter issued by any government
or governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any tax,
reserve, special deposit, capital adequacy or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from such
event), then, upon demand by such Lender or Lenders (through the Administrative
Agent), the Company shall pay immediately to the Administrative Agent for
account of such Lender or Lenders, from time to time as specified


                                Credit Agreement

<PAGE>


                                     - 45 -


by such Lender or Lenders (through the Administrative Agent), such additional
amounts as shall be sufficient to compensate such Lender or Lenders (through the
Administrative Agent) for such increased costs or reductions in amount. A
statement as to such increased costs or reductions in amount incurred by any
such Lender or Lenders, submitted by such Lender or Lenders to the Company,
shall be conclusive in the absence of manifest error as to the amount thereof.

                  Section 7.  Conditions Precedent.

                  7.01 Initial Extension of Credit. The obligation of any Lender
to make its initial extension of credit hereunder (whether by making a Loan or
issuing a Letter of Credit) is subject to the conditions precedent that (i) such
extension of credit shall be made on or before October 31, 1996, and (ii) the
Administrative Agent shall have received the following documents and other
evidence (with, in the case of clauses (a), (b), (c) and (d) below, sufficient
copies for each Lender), each of which shall be satisfactory to the
Administrative Agent (and to the extent specified below, to each Lender) in form
and substance (delivery to the Administrative Agent by a Lender of a signature
page hereto constituting conclusive evidence of such Lender's satisfaction as to
the fulfillment of the conditions precedent hereto):

                  (a) Corporate Documents. Certified copies of the charter and
         by-laws (or equivalent documents) of each Obligor and of all corporate
         authority for each Obligor (including, without limitation, board of
         director resolutions and evidence of the incumbency, including specimen
         signatures, of officers) with respect to the execution, delivery and
         performance of such of the Basic Documents to which such Obligor is
         intended to be a party and each other document to be delivered by such
         Obligor from time to time in connection herewith and the extensions of
         credit hereunder (and the Administrative Agent and each Lender may
         conclusively rely on such certificate until it receives notice in
         writing from such Obligor to the contrary).

                  (b)  Officer's Certificate.  A certificate of a senior
         officer of the Company, dated the Closing Date, to the
         effect set forth in the first sentence of Section 7.02
         hereof.

                  (c)  Opinion of Special New York Counsel to the
         Obligors.  An opinion, dated the Closing Date, of Sullivan &
         Worcester, special New York counsel to the Obligors,

         operating income by reason of any business interruption affecting the
         Company to the extent covered by standard business interruption
         policies in the States in which the Properties are located, but in any
         event in an amount of at least $5,000,000 per policy period, which
         insurance shall in each case cover gross earnings by reason of the
         particular Peril or other insurable business interruption and with a
         deductible (or self-insured amount) not in excess of $300,000 or, in
         California, 5% of the insured value of the property.

Such insurance shall be written by financially responsible companies selected by
the Company, having an A.M. Best rating of "A-" or better and in a financial
size category acceptable to the Majority Lenders, or by other companies
acceptable to the Majority Lenders.

year, then the shortfall shall be added to the amount of Capital Expenditures
permitted for the immediately succeeding fiscal year.

                  9.20 Modification of Other Agreements. The Company will not
request or consent to any modification, supplement or waiver of any of the

class of Capital Stock of each of such Person's Subsidiaries (other than, in
each case, Capital Stock of Excluded Subsidiaries). Without limiting the

Subsidiary) to issue any shares of Capital Stock of any class whatsoever to any
Person (other than to the Company or to another Wholly-Owned Subsidiary or
pursuant to Section 9.12 hereof). In the event that any such additional shares
of Capital Stock shall be issued by any Subsidiary of the Company, the Company
agrees forthwith to deliver to the Administrative Agent pursuant to the Security
Documents the certificates evidencing such shares of stock, accompanied by
undated stock powers executed in blank and shall take such other action as the
Administrative Agent shall request to perfect the security interest created
therein pursuant to the Security Documents.

                  (b) The Majority Lenders shall have the right from time to
time to require the Company, pursuant to a written request from the
Administrative Agent, to cause such Subsidiaries of the Company as may be
specified in such request to become parties to the Subsidiary Guaranty or to
execute and deliver such other guaranties, in form and substance satisfactory to
the Majority Lenders, guaranteeing payment of the Company's obligations
hereunder. Any such request shall be made by the Majority Lenders in the good
faith and reasonable exercise of their discretion. Within 30 days after any such
request, the Company shall, and shall cause the appropriate Subsidiaries of the
Company to, (i) execute and deliver to the Administrative Agent such number of
copies as the Administrative Agent may specify of documents creating such
guaranties and (ii) do all other things which may be necessary or which the
Administrative Agent may reasonably request in order to confer upon and confirm
to the Lenders the benefits of such security.

                  (c)  Notwithstanding anything to the contrary in this
Section 9.22, if:

         Subsidiaries of more than 66% of the aggregate Voting Stock
         of an Excluded Subsidiary

would, as determined in a resolution of the Board of Directors of the Company
delivered to the Administrative Agent, create a tax disadvantage that is
material in relation to the aggregate amount of the Investment or proposed
Investment therein by the Company and its Subsidiaries, then:

                  (I) such Excluded Subsidiary shall not be required to be or
         become a party to the Subsidiary Guaranty or otherwise Guarantee the
         obligations of the Company hereunder; and

                  (II) the Company and its Subsidiaries shall not be required to
         pledge more than 66% of the aggregate Voting Stock of such Excluded
         Subsidiary to the Administrative Agent under the Security Documents.

                  (d) The Company will not permit any of its Subsidiaries (other
than Excluded Subsidiaries) to enter into, after the date hereof, any indenture,
agreement, instrument or other arrangement (other than the Senior Subordinated
Debt Indenture) that, directly or indirectly, prohibits or restrains, or has the
effect of prohibiting or restraining, or imposes materially adverse conditions
upon, the incurrence or payment of Indebtedness, the granting of Liens, the
declaration or payment of dividends, the making of loans, advances or
Investments or the sale, assignment, transfer or other disposition of Property.

                  9.23 Environmental Matters. The Company will promptly give to
the Lenders notice in writing of any complaint, order, citation, notice or other
written communication from any Person with respect to, or if the Company becomes

liability, obligation, remedial action, loss, damage, cost, expense, fine,
penalty or sanction resulting from any air emission, water discharge, noise
emission, asbestos, Hazardous Substance or any other environmental, health or
safety matter at, upon, under or within any property now or previously owned,
leased, operated or used by the Company or any of its Subsidiaries or any part
thereof, or due to the operations or activities of the Company, any Subsidiary
or any other Person on or in connection with such property or any part thereof
(including receipt by the Company or any Subsidiary of any notice of the
happening of any event involving the Release or cleanup of any Hazardous
Substance), (ii) any Release on such property or any part thereof in a quantity
that is reportable under any applicable Environmental Law, (iii) the
commencement of any cleanup pursuant to or in accordance with any applicable
Environmental Law of any Hazardous Substances on or about such property or any
part thereof and (iv) any pending or threatened proceeding for the termination,
suspension or non-renewal of any permit required under any applicable
Environmental Law, in each of the cases (i), (ii), (iii) and (iv), (x) which
could result in liability or expenses in excess of $1,000,000 or (y) which
individually or in the aggregate could have a Material Adverse Effect.

permit any of its Subsidiaries to, create, incur or suffer to exist any Residual
Assurances, except that (notwithstanding Sections 9.08 and 9.14) the Company may
create a Residual Assurance with respect of the construction or

                  In addition, upon the occurrence and during the continuance of

payable), the Company agrees that it shall, if requested by the Administrative
Agent or the Majority Lenders through the Administrative Agent (and, in the case
of any Event of Default referred to in clause (f) or (g) of this Section 10.01

                  Section 11.  The Administrative Agent.

                  11.01 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
hereunder and under the other Basic Documents with such powers as are
specifically delegated to the Administrative Agent by the terms hereof and
thereof, together with such other powers as are reasonably incidental thereto.
The Administrative Agent (which term as used in this Section 11 shall include
reference to its affiliates and its own and its affiliates' officers, directors,
employees and agents): (a) shall have no duties or responsibilities except those
expressly set forth in this Agreement and the other Basic Documents, and shall
not by reason of this Agreement or any other

Basic Document be a trustee for any Lender; (b) shall not be responsible to the
Lenders for any recitals, statements, representations or warranties contained in
this Agreement or any other Basic Document, or in any certificate or other
document referred to or provided for in, or received by any of them under, this
Agreement or any other Basic Document, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Basic Document or any other document referred to or provided for
herein or therein or for any failure by the Company or any of the Subsidiary
Guarantors or any other Person to perform any of its obligations hereunder or
thereunder; (c) shall not be required to initiate or conduct any litigation or
collection proceedings hereunder or under any other Basic Document except to the
extent requested by the Majority Lenders; and (d) shall not be responsible for
any action taken or omitted to be taken by it hereunder or under any other Basic
Document or any other document or instrument referred to or provided for herein
or therein or in connection herewith or therewith, except for its own gross
negligence or willful misconduct. The Administrative Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.

                  11.02 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely upon any certification, notice or other
communication (including any thereof by telephone, telex, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel, independent accountants and other experts selected by the
Administrative Agent. As to any matters not expressly provided for by this
Agreement or any other Basic Document, the Administrative Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and
thereunder in accordance with instructions signed by the Majority Lenders and
such instructions of the Majority Lenders and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders.

                  11.03 Defaults. The Administrative Agent shall not be deemed
to have knowledge of the occurrence of a Default unless the Administrative Agent
has received notice from a Lender or the Company specifying such Default and
stating that such notice is a "Notice of Default". In the event that the
Administrative Agent receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice thereof to the Lenders. The
Administrative Agent shall (subject to Section 11.07 hereof) take such action
with respect to such Default as shall be directed by the Majority Lenders,
provided that, unless and until the Administrative Agent shall have


                                Credit Agreement

<PAGE>


                                     - 77 -


received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interests of the Lenders.
The Administrative Agent shall deliver to the Lenders a copy of any written
declaration made pursuant to the last paragraph of Section 10.01 hereof.

                  11.04 Rights as a Lender. With respect to its Commitments and
the Loans made by it, Chase in its capacity as a Lender hereunder shall have the
same rights and powers hereunder as any other Lender and may exercise the same
as though it were not acting as the Administrative Agent and the term "Lender"
or "Lenders" shall, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity. The Administrative Agent may
(without having to account therefor to any Lender) accept deposits from, lend
money to and generally engage in any kind of banking, trust or other business
with the Company and the Subsidiary Guarantors (and their respective Affiliates)
as if it were not acting as the Administrative Agent, and the Administrative
Agent may accept fees and other consideration from the Company (in addition to
the agency fees and arrangement fees heretofore agreed to between the Company
and the Administrative Agent) for services in connection with this Agreement or
otherwise without having to account for the same to the Lenders.

                  11.05 Indemnification. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed under Section 12.03 or 12.04
hereof, but without limiting the obligations of the Company under said Sections
12.03 and 12.04), ratably in accordance with the principal amount of their
respective Loans and Reimbursement Obligations outstanding, or if no Loans or
Reimbursement Obligations are outstanding, ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising out
of this Agreement or any other Basic Document or any other documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby (including, without limitation, the costs and
expenses which the Company is obligated to pay under Sections 12.03 and 12.04
hereof but excluding, unless a Default has occurred and is continuing, normal
administrative costs and expenses incident to the performance of its agency
duties hereunder) or the enforcement of any of the terms hereof or thereof or of
any such other documents, provided that no Lender shall be liable for any of the
foregoing to the extent they arise from the gross negligence or willful
misconduct of the party to be indemnified.

                  11.06 Non-Reliance on Administrative Agent and Other Lenders.
Each Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Company and decision to enter into this Agreement and that it will,
independently and without reliance upon the Administrative Agent or any other
Lender, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own analysis and decisions in taking or not
taking action under this Agreement or any of the other Basic Documents. The
Administrative Agent shall not be required to keep itself informed as to the
performance or observance by the Company and the Subsidiary Guarantors of this
Agreement or any of the other Basic Documents or any other document referred to
or provided for herein or therein or to inspect the properties or books of the
Company or any of the Subsidiary Guarantors. Except for notices, reports and
other documents and information expressly required to be furnished to the
Lenders by the Administrative Agent hereunder or the other Basic Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Company or any of the Subsidiary Guarantors (or any
of their affiliates) which may come into the possession of the Administrative
Agent.

                  11.07 Failure to Act. Except for action expressly required of
the Administrative Agent hereunder and under the other Basic Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction by the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action.

                  11.08 Resignation or Removal of Administrative Agent. Subject
to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Company and the Administrative Agent may be
removed at any time with or without cause by the Majority Lenders. Upon any such
resignation or removal the Majority Lenders shall have the right to appoint a
successor Administrative Agent reasonably acceptable to the Company. Upon any
such resignation or removal, the Administrative Agent that resigned or was
removed shall, to the extent that its annual agency fee was paid in advance, pay
to the Company an amount equal to such fee multiplied by a fraction the
numerator of which shall be the number of days remaining on the date of such
resignation or removal until the next anniversary of the Closing Date, and the
denominator of which

by the Majority Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent's giving of notice of resignation or the
Majority Lenders' removal of the retiring Administrative Agent (the "Notice
Date"), then the retiring Administrative Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent reasonably acceptable to the Company.
Any successor Administrative Agent shall be (i) a Lender or (ii) if no Lender
has accepted such appointment within 30 days after the Notice Date, a bank which
has an office in New York, New York with a combined capital and surplus of at
least $250,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After any retiring Administrative Agent's resignation or
removal hereunder as Administrative Agent, the provisions of this Section 11
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent.

                  11.09 Consents under Basic Documents. Without the prior
written consent of the Majority Lenders, the Administrative Agent will not
consent to any modification, supplement or waiver under any of the Basic
Documents or any of the other documents described in Section 9.20 hereof.

                  11.10 Collateral Sub-Agents. Each Lender by its execution and
delivery of this Agreement agrees, as contemplated by the Security Documents,
that, in the event it shall hold any Liquid Investments referred to therein,
such Liquid Investments shall be held in the name and under the control of such
Lender and such Lender shall hold such Liquid Investments as a collateral
sub-agent for the Administrative Agent thereunder.


                  Section 12.  Miscellaneous.

                  12.01 Waiver. No failure on the part of the Administrative
Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under any Basic Document
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege thereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The remedies
provided in the Basic Documents are cumulative and not exclusive of any remedies
provided by law.

Note (the participant's rights against such Lender in respect of such

information concerning the Company and its Subsidiaries in the possession of
such Lender from time to time to assignees and participants (including
prospective assignees and participants) which have agreed in writing to be bound
by the provisions of Section 12.07 hereof. The Administrative Agent and the
Company may, for all purposes of this Agreement, treat any Lender as the holder
of any Note drawn to its order (and owner of the Loans evidenced thereby) until
written notice of assignment, participation or other transfer shall have been
received by them from such Lender.

such information in accordance with customary banking practices and who receive
such information having been made aware of the restrictions set forth in this
Section, (iii) upon the order of any court or administrative agency, (iv) upon

extent reasonably required in connection with the exercise of any remedy
hereunder, (vii) to such Lender's legal counsel and independent auditors, and

                  12.11 Additional Lenders. The Company, each of the Lenders and
the Administrative Agent may at any time agree to add one or more lenders to
this Agreement pursuant to an instrument in writing specifying such new lender's
Commitments (and the reduction in Commitments of the existing Lenders as a
result thereof in such manner as the Company, each of the Lenders and the

AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.
