(3) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

    The Company adopted the provisions of SFAS No. 133, Accounting for
Derivative Instruments and Hedging Activities, on January 1, 2001. SFAS No. 133
requires that every derivative instrument be recorded in the balance sheet as
either an asset or a liability measured at its fair value. The adoption of SFAS
No. 133 on January 1, 2001 resulted in the recognition of a derivative liability
and a corresponding transition adjustment charge to accumulated other
comprehensive items of approximately $214.

    Periodically, the Company acquires derivative instruments that are intended
to hedge either cash flows or values which are subject to exchange or other
market price risk, and not for trading purposes. The Company has formally
documented its hedging relationships, including identification of the hedging
instruments and the hedge items, as well as its risk management objectives and
strategies for undertaking each hedge transaction.

    The Company has entered into three interest rate swap agreements, which are
derivatives as defined by SFAS No. 133 and designated as cash flow hedges. These
swap agreements hedge interest rate risk on certain amounts of its Tranche B
debt as well as certain variable operating lease commitments. For all qualifying
and highly effective cash flow hedges, the changes in the fair value of the
derivatives are recorded in other comprehensive income. As a result of these
interest rate swap agreements, the Company has recorded a derivative liability
of and a corresponding charge to accumulated other comprehensive items of
approximately $4,254 at March 31, 2001.

    During the period ending March 31, 2001, the Company recorded net losses of
$59 and $9 resulting from interest rate swap settlements in interest and rent
expense, respectively. All interest rate swap agreements were determined to be
highly effective whereby no ineffectiveness was recorded in earnings.

(4) ACQUISITIONS

    During the three months ended March 31, 2001, the Company purchased
substantially all of the assets, and assumed certain liabilities, of six records
and information management services businesses.

    Each of the 2001 acquisitions and all 12 of the records and information
management services businesses acquired during 2000 were 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 their respective acquisition dates. In connection with certain 2001 and
2000 acquisitions, related real estate was also purchased. The aggregate
purchase price for the 2001 acquisitions exceeded the underlying fair value of
the net assets acquired by $29,255 which has been assigned to goodwill and is
being amortized over 25 to 30 years.

    In connection with the 2001 and 2000 acquisitions, the Company has
undertaken certain restructurings of the acquired businesses. The restructuring
activities include certain reductions in staffing levels, elimination of
duplicate facilities and other costs associated with exiting certain activities
of the acquired businesses. These restructuring activities were recorded as
costs of the acquisitions and were provided in accordance with Emerging Issues
Task Force Issue No. 95-3, "Recognition of

finalizes its restructuring plans for each business no later than one year from
the date of acquisition. Unresolved matters primarily include completion of
planned abandonments of facilities and employee severance costs for certain 2001
and 2000 acquisitions.

    The following is a summary of reserves related to such restructuring
activities:



                                                        MARCH 31,   DECEMBER 31,

    At March 31, 2001, the restructuring reserves related to acquisitions
consisted of lease losses on abandoned facilities ($15,783), severance costs for
approximately 16 people ($1,376) and other exit costs ($7,565). These accruals
are expected to be used within one year of the finalization of the restructuring
plans except for lease losses of $10,302 and severance contracts of
approximately $674, all of which are based on contracts that extend beyond one
year.

10 1/8% notes, 9 1/8% notes, 8 3/4% notes, 8 1/4% notes (collectively, the

(7) EARNINGS PER SHARE

   In accordance with SFAS No. 128, "Earnings per Share," basic net income
(loss) per common share is calculated by dividing net income (loss) by the
weighted average number of common shares outstanding. The calculation of diluted
net income (loss) per share is consistent with that of basic net income (loss)
per share but gives effect to all potential common shares (that is, securities
such as options, warrants or convertible securities) that were outstanding
during the period, unless the effect is antidilutive.

(9) SUBSEQUENT EVENTS

    In April 2001, Iron Mountain completed an underwritten public offering of
$225,000 in aggregate principal amount of 8 5/8% Senior Subordinated Notes due
2013. The 8 5/8% notes were issued at a price to investors of 100% of par. The
net proceeds to the Company, approximately $219,000 after paying the
underwriters' discounts and commissions and estimated expenses, were used to
fund the Company's offer to purchase and consent solicitation relating to its
outstanding 11 1/8% Senior Subordinated Notes due 2006, to repay outstanding
borrowings under the Company's revolving credit facility and for general
corporate purposes, including acquisitions.

    In April 2001, the Company received and accepted tenders for $124,588 of the
outstanding principal amount of its 11 1/8% notes. The Company expects to record
an extraordinary charge of approximately $5,000 (net of tax benefit) in the
second quarter related to the early retirement of the 11 1/8% notes. The Company
intends to redeem the remaining $5,412 of outstanding principal amount of the
11 1/8% notes in July 2001, the first redemption date, at a redemption price
(expressed as a percentage of principal amount) of 105.563%, plus accrued and
unpaid interest to, but not including, the date of redemption.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS

    The following discussion and analysis of the Company's financial condition
and results of operations for the three months ended March 31, 2001 and 2000
should be read in conjunction with the condensed consolidated financial
statements and footnotes for the three months ended March 31, 2001 included
herein, and the year ended December 31, 2000, included in the Company's Annual
Report on Form 10-K filed with the Securities and Exchange Commission on
March 23, 2001.

OVERVIEW

    The Company's consolidated revenues increased $71.8 million, or 33.8%, to
$283.9 million for the first quarter of 2001 from $212.1 million for the first
quarter of 2000. Internal revenue growth, calculated in local currency for our
international operations and as if Pierce Leahy Corp. had merged with Iron
Mountain on January 1, 2000, was 11.2%.

    During the first quarter of 2001, the Company acquired six records and
information management services businesses for total consideration of
$41.0 million. These six acquisitions reported approximately $15 million in
revenues for the fiscal year 2000.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2001 COMPARED TO THREE MONTHS ENDED MARCH 31, 2000

    Consolidated storage revenues increased $42.9 million, or 34.4%, to
$167.9 million for the first three months of 2001, from $124.9 million for the
first three months of 2000. The increase was attributable to: (i) acquisitions,
particularly the Pierce Leahy acquisition; and (ii) internal revenue growth of
12.7% resulting primarily from net increases in records and other media stored
by existing customers, price increases and sales to new customers. The total
increase in storage revenues was partially offset by the unfavorable effects of
currency translation as a result of the strengthening of the U.S. dollar against
certain foreign currencies, primarily the Canadian dollar and the British pound
sterling, in which the Company's international segment does business.

    Consolidated service and storage material sales revenues increased
$28.9 million, or 33.1%, to $116.1 million for the first three months of 2001,
from $87.2 million for the first three months of 2000. The increase was
attributable to: (i) acquisitions, particularly the Pierce Leahy acquisition;
and (ii) internal revenue growth of 9.0% resulting primarily from net increases
in service and storage material sales to existing customers, price increases and
sales to new customers. The total increase in service and storage material sales
revenues was partially offset by the unfavorable effects of currency translation
as a result of the strengthening of the U.S. dollar against certain foreign
currencies, primarily the Canadian dollar and the British pound sterling, in
which the Company's international segment does business.

    For the reasons discussed above, total consolidated revenues increased
$71.8 million, or 33.8%, to $283.9 million for the first three months of 2001
from $212.1 million for the first three months of 2000.

    Consolidated cost of sales (excluding depreciation) increased
$35.4 million, or 33.9%, to $139.8 million (49.2% of consolidated revenues) for
the first three months of 2001 from $104.5 million (49.2% of consolidated
revenues) for the first three months of 2000. The dollar increase was consistent
with the revenue growth of the Company.

    Consolidated selling, general and administrative expenses increased
$16.9 million, or 31.5%, to $70.3 million (24.8% of consolidated revenues) for
the first three months of 2001 from $53.5 million (25.2% of consolidated
revenues) for the first three months of 2000. The dollar increase was primarily

                                       18

                           IRON MOUNTAIN INCORPORATED

attributable to revenue growth of the Company. The percentage decrease was
primarily attributable to general management overhead efficiencies due to an
increase in scale partially offset by: (i) increased spending in Europe and
Latin America as a percentage of revenues and (ii) spending in the first quarter
of 2001 for the Company's marketing and information technology initiatives
related to the development of complementary technology-based service offerings.

    As a result of the foregoing factors, consolidated EBITDA increased
$19.6 million, or 36.1%, to $73.8 million (26.0% of consolidated revenues) for
the first three months of 2001 from $54.2 million (25.6% of consolidated
revenues) for the first three months of 2000. Excluding the $0.9 million of
expenses related to the Company's technology-related service offerings, the
Company's EBITDA margin for the first three months of 2001 was 26.3% of
consolidated revenues. There were no such costs in the first three months of
2000.

    Consolidated depreciation and amortization expense increased $9.4 million,
or 35.8%, to $35.7 million (12.6% of consolidated revenues) for the first three
months of 2001 from $26.3 million (12.4% of consolidated revenues) for the first
three months of 2000. The dollar increase was primarily attributable to the
additional depreciation and amortization expense related to the 2000 and 2001
acquisitions, particularly the Pierce Leahy acquisition, and capital
expenditures including racking systems, information systems and expansion of
storage capacity in existing facilities.

    Merger-related expenses are certain expenses directly related to the
Company's merger with Pierce Leahy that cannot be capitalized and include system
conversion costs, costs of exiting certain facilities, severance, relocation and
pay-to-stay payments and other transaction-related costs. Merger-related
expenses were $0.8 million for the first three months of 2001 compared to
$0.5 million for the first three months of 2000.

    As a result of the foregoing factors, consolidated operating income
increased $9.9 million, or 36.0%, to $37.3 million (13.1% of consolidated
revenues) for the first three months of 2001 from $27.4 million (12.9% of
consolidated revenues) for the first three months of 2000.

    Consolidated interest expense increased $10.2 million, or 42.9%, to
$34.0 million for the first three months of 2001 from $23.8 million for the
first three months of 2000. The increase was primarily attributable to increased
indebtedness related to: (i) the inclusion of Pierce Leahy's debt for three
months of 2001 versus two months of 2000 and (ii) the financing of acquisitions
and capital expenditures.

    Consolidated other expense was $9.2 million for the first three months of
2001 compared to $0.8 million for the first three months of 2000. The increase
was primarily due to a weakening of the Canadian dollar against the U.S. dollar,
as it relates to Canada Company's 8 1/8% Senior Subordinated Notes due 2008 and
on intercompany balances with the Company's Canadian subsidiaries and a
weakening of the British pound sterling against the U.S. dollar on intercompany
balances with the Company's European subsidiaries.

    As a result of the foregoing factors, consolidated income (loss) before
provision (benefit) for income taxes and minority interest decreased
$8.7 million to a loss of $5.9 million (2.1% of consolidated revenues) for the
first three months of 2001 from income of $2.8 million (1.3% of consolidated
revenues) for the first three months of 2000. The benefit for income taxes was
$8.8 million for the first three months of 2001 compared to a provision of
$8.5 million for the first three months of 2000. The benefit was calculated by
applying the Company's effective tax rate to the pre-tax loss. The Company's
effective tax rate is based on an estimate of annual pre-tax income and is
higher than statutory rates primarily due to the amortization of the
nondeductible portion of goodwill associated

                           IRON MOUNTAIN INCORPORATED

with particular acquisitions. For the three months ended March 31, 2001, the
Company recorded $9.6 million in nondeductible goodwill amortization expense.

    Consolidated net income increased $8.6 million to $3.2 million (1.1% of
consolidated revenues) for the first three months of 2001 from a net loss of
$5.4 million (2.5% of consolidated revenues) for the first three months of 2000.

LIQUIDITY AND CAPITAL RESOURCES

    As the Company has sought to increase its EBITDA, it has made significant
capital investments, consisting primarily of: (i) capital expenditures,
primarily related to growth (including investments in real estate, racking
systems, information systems and expansion of storage capacity in existing
facilities); (ii) acquisitions; and (iii) customer acquisition costs. Cash paid
for these investments during the first three months of 2001 amounted to
$48.2 million, $34.8 million and $2.3 million, respectively. These investments
have been primarily funded through cash flows from operations and borrowings
under the Company's credit agreements. Included in capital expenditures is
$1.5 million related to the Company's technology-based service offerings.

    Net cash provided by operations was $23.9 million for the first three months
of 2001 compared to $17.7 million for the same period in 2000. The increase
primarily resulted from an increase in EBITDA and an increase in accrued
expenses, which was partially offset by an increase in trade accounts receivable
and a decrease in the net deferred tax liability.

    Net cash provided by financing activities was $66.9 million for the first
three months of 2001, consisting primarily of the proceeds from borrowings under
the Company's revolving credit facility of $81.8 million and equity
contributions from minority shareholders of $24.5 million, which were partially
offset by repayments of debt of $35.7 million.

    In April 2001, Iron Mountain completed an underwritten public offering of
$225.0 million in aggregate principal amount of 8 5/8% Senior Subordinated Notes
due 2013. The 8 5/8% notes were issued at a price to investors of 100% of par.
The net proceeds to the Company, approximately $219 million after paying the
underwriters' discounts and commissions and estimated expenses, were used to
fund the Company's offer to purchase and consent solicitation relating to its
outstanding 11 1/8% Senior Subordinated Notes due 2006, to repay outstanding
borrowings under the Company's revolving credit facility and for general
corporate purposes, including acquisitions.

    In April 2001, the Company received and accepted tenders for $124.6 million
of the outstanding principal amount of its 11 1/8% notes. The Company expects to
record an extraordinary charge of approximately $5 million (net of tax benefit)
in the second quarter related to the early retirement of the 11 1/8% notes. The
Company intends to redeem the remaining $5.4 million of outstanding principal
amount of the 11 1/8% notes in July 2001, the first redemption date, at a
redemption price (expressed as a percentage of principal amount) of 105.563%,
plus accrued and unpaid interest to, but not including, the date of redemption.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    In December 2000 and January 2001, the Company entered into certain
derivative financial contracts, which were variable-for-fixed swaps of interest
payments payable on the Company's Tranche B term loan and certain variable
operating lease commitments.

    Iron Mountain's investments in Iron Mountain Europe Limited, Iron Mountain
South America, Ltd. and other international investments may be subject to risks
and uncertainties relating to fluctuations in currency valuation. One of the
Company's Canadian subsidiaries, Canada Company, has U.S. dollar denominated
debt. Gains and losses due to exchange rate fluctuations related to this debt
are recognized in the Company's consolidated statements of operations.

    As of March 31, 2001, the Company had $230.3 million of variable rate debt
outstanding with a weighted average interest rate of 7.72% and $1,172.8 million
of fixed rate debt outstanding. If the weighted average variable interest rate
had increased by 1%, such increase would have had a negative impact on the
Company's net income for the quarter ended March 31, 2001 of $0.3 million. See
Note 4 of Notes to Consolidated Financial Statements for a discussion of the
Company's long-term indebtedness, including the fair values of such indebtedness
as of March 31, 2001.
