                              PIERCE LEAHY CORP.
              ITEM 1 - NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           (unaudited, in thousands except share and per share data)


(1)      GENERAL:

         The interim consolidated financial statements presented herein have
         been prepared by Pierce Leahy Corp. ("Pierce Leahy" 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 consolidated balance sheet as of December 31, 1996 has been derived
         from the Company's consolidated financial statements that have been
         audited by the Company's independent public accountants. The unaudited
         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. The consolidated financial statements and notes
         included herein should be read in conjunction with the consolidated
         financial statements and notes for the year ended December 31, 1996,
         included in the Company's Annual Report on Form 10-K and the Company's
         Registration Statement on Form S-1 (File number 333-23121).


(2)      ACQUISITIONS:

         During 1996, the Company purchased twelve records management
         businesses. During the nine months ended September 30, 1997, eleven
         records management businesses were purchased by the Company. Ten of the
         eleven acquisitions recorded during the nine months ended September 30,
         1997 were accounted for using the purchase method of accounting and,
         accordingly, the results of operations for such acquisitions have been
         included in the consolidated results of the Company from their
         respective acquisition dates. One acquisition has been accounted for
         using the pooling of interests method. The Company issued 92,507 shares
         of Common Stock in connection with this acquisition. The impact of this
         acquisition on the consolidated financial position and results of
         operations was not material and, as such, the prior period consolidated
         financial statements were not restated for this transaction. The
         results of operations for this acquisition have been included in the
         consolidated results of the Company from its acquisition date. The
         purchase price for the ten 1997 acquisitions accounted for by the
         purchase method exceeded the underlying fair market value of the net
         assets acquired by $75,961, which amount has been assigned to goodwill
         and is being amortized over the estimated benefit period of 30 years.
         For the ten acquisitions, the Company paid an aggregate of
         approximately $92,451 in cash which was provided primarily from the
         Company's credit facility and (approximately $6,000) from proceeds from
         the Company's initial public offering.

(4)      EQUITY AND DEBT OFFERINGS:

         On July 7, 1997, Pierce Leahy completed an initial public offering of
         5,664,017 shares of its Common Stock (the "Equity Offering").
         Concurrent with the Equity Offering, the Company also issued $120,000
         principal amount of 9 1/8% Senior Subordinated Notes due 2007 (the
         "Notes Offering").

         A substantial portion of the net proceeds of the Equity Offering was
         used to redeem $70,000 of the Company's 11 1/8% Senior Subordinated
         Notes (the "1996 Notes") on August 1, 1997 at their face amount plus a
         $7,000 (pretax) premium incurred in connection with the redemption. The
         net proceeds from the Notes Offering were primarily used to repay
         existing amounts outstanding under the Company's credit facility. The
         remainder of the net proceeds of the offerings was used for general
         corporate purposes and acquisitions.

         The Company recorded a charge of $3,050 relating to the write-off of
         unamortized deferred financing costs on the redeemed 1996 Notes and
         fees associated with the repayment of the Company's prior credit
         facility. These items (plus the $7,000 premium paid for the redemption)
         resulted in an extraordinary charge of $6,036, net of the related tax
         benefit of $4,014, in the third quarter of 1997.

(5)      SPECIAL COMPENSATION CHARGE:

         In the third quarter of 1997, a special compensation charge of $1,752
         was incurred for the write-off of the unamortized compensation expense
         due to the acceleration of vesting of stock options granted on January
         1, 1997.


(6)      INCOME TAX EXPENSE:

         Income taxes of $7,298 for the three and nine month periods ended
         September 30, 1997 are comprised of two factors: (1) a $6,600 provision
         in connection with the termination of the Company's status as a
         Subchapter S corporation; and (2) a $698 provision related to current
         periods results from July 1, 1997 (date of termination of Subchapter S
         corporation status) through September 30, 1997.


(7)      PRO FORMA INCOME TAXES:

         Prior to June 30, 1997, Pierce Leahy was a Subchapter S corporation for
         federal income tax purposes and, accordingly, income and loss were
         passed through to the shareholders. The Subchapter S corporation status
         was terminated in conjunction with the Equity Offering on July 1, 1997.
         The pro forma income tax provision assumes the Company had been treated
         as a C corporation for income tax purposes for the nine month period
         ended September 30, 1997.

(8)      SUBSEQUENT EVENTS:

         Subsequent to September 30, 1997, the Company completed three
         additional acquisitions; Records Management and Protection (New
         Orleans, LA), Davidson Archives (Kansas City, MO), and Datafilms, Inc.
         d/b/a Medical Administration Company (Denver, CO). The total
         consideration for these three acquisitions was approximately $10,050.
         Two of these transactions will be accounted for under the purchase
         method of accounting and one will be accounted for under the pooling of
         interests method of accounting.

               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 and nine month periods ended September 30,
1996 and 1997 should be read in conjunction with the consolidated financial
statements and footnotes for the three and nine month periods ended September
30, 1996 and 1997, included herein, and the consolidated financial statements
and footnotes for the year ended December 31, 1996, included in the Company's
Annual Report on Form 10-K and the Company's Registration Statement on Form S-1
(File number 333-23121).

Results of Operations

Three Months Ended September 30, 1996 Compared to Three Months Ended September
30, 1997

Total revenues increased from $32.5 million for the three months ended September
30, 1996 to $47.2 million for the three months ended September 30, 1997, an
increase of $14.7 million, or 45.3%. Sixteen acquisitions were completed from
October 1996 to September 1997 which accounted for $9.5 million, or 64.6%, of
such increase in total revenues. The balance of the revenue growth resulted from
sales to new customers and from net increases in cubic feet stored from existing
customers.

Storage revenues increased from $19.3 million for the three months ended
September 30, 1996 to $27.9 million for the three months ended September 30,
1997, an increase of $8.6 million, or 44.7%. Service and storage material sales
revenues increased from $13.2 million for the three months ended September 30,
1996 to $19.4 million for the three months ended September 30, 1997, an increase
of $6.1 million, or 46.2%.

Cost of sales (excluding depreciation and amortization) increased from $17.7
million in the three months ended September 30, 1996 to $25.9 million in the
three months ended September 30, 1997, an increase of $8.2 million, or 46.5%,
and increased slightly as a percentage of total revenues from 54.5% in the 1996
period to 54.9% in the 1997 period. The $8.2 million increase in cost of sales
resulted primarily from an increase in cubic feet stored associated with the
growth in business. The integration of Records Management Systems, Inc. ("RMS"),
acquired in April 1997 and which operates in nine cities, also contributed to
the slight increase in cost of sales as a percentage of total revenues.

Selling, general and administrative expenses increased from $5.0 million for the
three months ended September 30, 1996 to $7.1 million for the three months ended
September 30, 1997, an increase of $2.1 million, or 41.1%, but decreased as a
percentage of total revenues from 15.5% in the 1996 period to 15.0% in the 1997
period. The dollar increase was primarily attributable to increases in staffing,
including increases in sales force and administrative staff. The decrease as a
percentage of total revenues was attributable to economies realized from
operating administratively in a centralized manner and using the Company's
proprietary PLUS software system. The Company also began to realize some of the
efficiencies from the integration of administrative functions of RMS during the
1997 period. 


                                    - 10 -

 
Depreciation and amortization expense increased from $3.2 million for the three
months ended September 30, 1996 to $5.6 million for the three months ended
September 30, 1997, an increase of $2.4 million, or 73.9%, and increased as a
percentage of revenues from 10.0% for the three months ended September 30, 1996
to 11.9% for the three months ended September 30, 1997. The increase was
primarily attributable to the additional depreciation and amortization expense
related to the sixteen acquisitions completed from October 1996 to September
1997 and to capital expenditures for buildings, shelving, improvements to
records management facilities and information systems, and client acquisition
costs.

The Company incurred a non-recurring charge of $3.3 million, or 10.0%, of total
revenues in the three months ended September 30, 1996 relating to the purchase
of real estate from affiliated parties completed in connection with the sale of
the Company's 1996 Notes.

A special compensation charge of $1.8 million was incurred during the three
months ended September 30, 1997. This charge related to the write-off of the
unamortized compensation expense due to the acceleration of vesting of stock
options granted on January 1, 1997.

Interest expense increased from $5.4 million for the three months ended
September 30, 1996 to $7.4 million for the three months ended September 30,
1997, an increase of $2.0 million, or 37.0%. The increase was primarily
attributable to increased indebtedness related to financing acquisitions and
capital expenditures. Interest expense was also affected by the lower interest
income earned on $77.0 million held in escrow for approximately one month from
the Equity Offering until the redemption of a portion of the 1996 Notes, which
bear interest at 11 1/8%, on August 1, 1997.

As a result of the foregoing factors, the Company incurred a loss before income
taxes and extraordinary item of $2.1 million (-6.4% of revenues) for the three
months ended September 30, 1996 compared to a loss before income taxes and
extraordinary item of $0.6 million (-1.2% of revenues) for the three months
ended September 30, 1997.

The Company recorded income taxes of $7.3 million (or 15.4% of revenues) for the
three months ended September 30, 1997. These taxes were comprised of the tax
effect from the termination of the Company's Subchapter S status and the
provision for the results of the three months ended September 30, 1997. There
were no income taxes in the three months ended September 30, 1996 since the
Company operated as a Subchapter S corporation during such period.

The extraordinary items of $2.0 million (or 6.2% of total revenues) for the
three months ended September 30, 1996 and $6.0 million (12.8% of total revenues)
for the three months ended September 30, 1997 related to losses on early
extinguishment of debt. The $6.0 million extraordinary item for the three months
ended September 30, 1997 is net of a tax benefit of $4.0 million.

As a result of the foregoing items, the net loss for the three months ended
September 30, 1996 and 1997 was $4.1 million (-12.6% of revenues) and $13.9
million (-29.4% of revenues), respectively.

Earnings before interest, taxes, depreciation and amortization, non-recurring
charge, special compensation charge, and foreign currency translation ("EBITDA")
increased from $9.8 million for the three months ended September 30, 1996 to
$14.2 million for the three months ended September 30, 1997, an increase of $4.4
million, or 45.4%. As a percentage of revenues, EBITDA remained the same at
30.1% for the three months ended September 30, 1996 and 1997.

Nine Months Ended September 30, 1996 Compared to Nine Months Ended September 30,
1997

Total revenues increased from $93.8 million for the nine months ended September
30, 1996 to $133.7 million for the nine months ended September 30, 1997, an
increase of $39.9 million, or 42.5%. Sixteen acquisitions completed from October
1996 to September 30, 1997 accounted for $22.9 million, or 57.4%, of such
increase in total revenues. The balance of the revenue growth resulted from
sales to new customers and from net increases in cubic feet stored from existing
customers

Storage revenues increased from $54.8 million for the nine months ended
September 30, 1996 to $77.9 million for the nine months ended September 30,
1997, an increase of $23.2 million, or 42.3%. Service and storage material sales
revenues increased from $39.1 million for the nine months ended September 30,
1996 to $55.8 million for the nine months ended September 30, 1997, an increase
of $16.7 million, or 42.8%.

Cost of sales (excluding depreciation and amortization) increased from $52.9
million in the nine months ended September 30, 1996 to $73.9 million in the nine
months ended September 30, 1997, an increase of $21.0 million, or 39.6%, but
decreased as a percentage of total revenues from 56.4% in 1996 to 55.2% in 1997.
The $21.0 million increase in cost of sales resulted primarily from an increase
in cubic feet associated with the growth in business. The decrease in cost of
sales as a percentage of total revenues was due primarily to operating and
storage efficiencies.

Selling, general and administrative expenses increased from $14.9 million for
the nine months ended September 30, 1996 to $21.3 million for the nine months
ended September 30, 1997, an increase of $6.3 million, or 42.3%, and remained
the same as a percentage of revenues at 15.9%. The dollar increase was primarily
attributable to increases in staffing, including increases in the Company's
sales forces and increases due to acquisitions.

Depreciation and amortization expense increased from $8.8 million for the nine
months ended September 30, 1996 to $15.1 million for the nine months ended
September 30, 1997, an increase of $6.2 million, or 70.1%, and increased as a
percentage of revenues from 9.4% for the nine months ended September 30, 1996 to
11.3% for the nine months ended September 30, 1997. The increase was primarily
attributable to the additional depreciation and amortization expense related to
the sixteen acquisitions completed from October 1996 to September 1997 and to
capital expenditures for buildings, shelving, improvements to records management
facilities and information systems, and client acquisition costs.

The Company incurred a non-recurring charge of $3.3 million, or 3.5%, of total
revenues in the nine months ended September 30, 1996 related to the purchase of
real estate from affiliated parties completed in connection with the sale of the
Company's 1996 Notes.

A special compensation charge of $1.8 million was incurred during the nine
months ended September 30, 1997. This charge relates to the write-off of the
unamortized compensation expense due to the acceleration of vesting of stock
options granted on January 1, 1997.

Interest expense increased from $11.3 million for the nine months ended
September 30, 1996 to $22.2 million for the nine months ended September 30,
1997, an increase of $10.9 million, or 96.2%. The increase was primarily
attributable to increased indebtedness related to financing acquisitions and
capital expenditures, as well as the higher interest rate on the Company's 9
1/8% Senior Subordinated Notes issued in July 1997 compared to the bank debt
repaid upon the issuance of such Notes. Interest expense was also affected by
the lower interest income earned on $77.0 million held in escrow for
approximately one month from the Equity Offering until the redemption of a
portion of the 1996 Notes, which bear interest at 11 1/8%, on August 1, 1997.

As a result of the foregoing factors, the Company had income before income taxes
and extraordinary item of $2.6 million (2.7% of revenues) for the nine months
ended September 30, 1996 compared to a loss of $0.6 million (-0.5% of revenues)
for the nine months ended September 30, 1997.

The Company recorded income taxes of $7.3 million (or 5.5% of revenues) for the
nine months ended September 30, 1997. These taxes were comprised of the tax
effect from the termination of the Company's Subchapter S status and the
provision for the results of operations after the termination of its status as
an S Corporation on July 1, 1997. There were no income taxes in the nine months
ended September 30, 1996 since the Company operated as a Subchapter S
corporation during such period.

The extraordinary items of $2.0 million (or 2.1% of total revenues) for the nine
months ended September 30, 1996 and $6.0 (4.5% of total revenues) for the nine
months ended September 30, 1997 related to losses on early extinguishment of
debt. The $6.0 million extraordinary item for the nine months ended September
30, 1997 is net of a tax benefit of $4.0 million.

As a result of the foregoing items, the Company had net income of $0.6 million
and a net loss of $13.9 million for the nine months ended September 30, 1996 and
1997, respectively.

EBITDA increased from $26.0 million for the nine months ended September 30, 1996
to $38.6 million for the nine months ended September 30, 1997, an increase of
$12.6 million, or 48.4%. As a percentage of revenues, EBITDA increased from
27.7% for the nine months ended September 30, 1996 to 28.9% for the nine months
ended September 30, 1997.

Liquidity and Capital Resources

The Company has made significant investments, consisting primarily of (i)
acquisitions, (ii) capital expenditures for buildings, shelving, improvements to
records management facilities and information systems, and (iii) client
acquisition costs. Cash paid for these investments during the nine months ended
September 30, 1997 was $92.5 million, $27.1 million and $6.9 million,

                                    - 13 -

 
respectively. These investments were primarily funded with the net proceeds of
the Company's equity and debt offerings and the borrowings under the Company's
credit facility.

During the nine months ended September 30, 1996, the Company generated $11.5
million in net cash provided by operations as compared to net cash provided by
operations of $6.3 million for the nine months ended September 30, 1997. The
$5.2 million decrease in net cash provided by operations for the nine months
ended September 30, 1997 compared to the prior year period resulted from a
decrease in net income of $14.5 million, an $11.1 million decrease in working
capital, of which $11.4 million was a result of reductions in accrued expenses
and accounts payable, offset by an increase in deferred income taxes of $7.3
million, an increase of $6.2 million in depreciation and amortization, an
increase in extraordinary items of $4.0 million, and an increase in special
compensation charge of $1.8 million.

The net cash provided by financing activities for the nine months ended
September 30, 1997 was $128.7 million, consisting primarily of $120.0 million of
gross proceeds from the issuance of the 1997 Notes and $93.5 million net
proceeds from the issuance of Common stock, offset by the repayment of long-term
debt of $77.1 million and the $7.0 million prepayment premium on the redemption
of a portion of the 1996 Notes. As of September 30, 1997, the Company had $2.0
million of available cash and cash equivalents and a credit facility providing
for $140.0 million of U.S. dollar borrowings and $35.0 million of Canadian
dollar borrowings. As of September 30, 1997, $6.5 million was outstanding under
the credit facility.
