PAGE Unaudited Pro Forma Condensed Consolidated Statement of Operations for the six months ended June 30, 2000 2 Unaudited Pro Forma Condensed Consolidated Statement of Operations for the year ended December 31, 1999 3 Schedule A- Schedule of 1999 Pro Forma Acquisitions for the year ended December 31, 1999 4 Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements 5-13 IRON MOUNTAIN INCORPORATED UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION The term pro forma transactions, as used in the accompanying pro forma condensed consolidated financial statements and notes thereto, is defined as certain of our 1999 and 2000 acquisitions and certain financing transactions and includes the following: (a) the acquisitions of Iron Mountain Europe Limited ("Iron Mountain Europe") (50.1% interest), First American Records Management Inc. ("FARM"), Data Base, Inc. ("Data Base"), MAP, S.A. (Memogarde) ("Memogarde") by Iron Mountain Europe, Central File, Inc. ("Central File"), Sistemas de Archivo Corporativo, S. de R.L. de C.V. (50.1% interest) ("Sistemas de Archivo Corporativo"), Stortext (Holdings) Ltd. ("Stortext") by Iron Mountain Europe, Midtown Professional Records Center, Inc. ("Midtown"), Pierce Leahy Corp. ("Pierce Leahy"), and Data Storage Center, Inc. ("DSC"); (b) the issuance of $150 million 8 1/4% senior subordinated notes in April 1999; (c) the sale of 5.8 million shares of common stock in May 1999; (d) Iron Mountain's repurchase of shares issued in connection with the Data Base acquisition for $39.5 million on May 18, 1999 and (e) the Company's amendment to its revolving credit facility effective February 1, 2000, as if each had occurred as of January 1, 1999. The pro forma condensed consolidated financial statements separately present the pro forma effects of the DSC acquisition and the Pierce Leahy merger. You should read the pro forma financial statements in conjunction with our Current Reports on Form 8-K filed with the Securities and Exchange Commission ("SEC") on February 1, 2000, May 4, 2000, and May 15, 2000; our 1999 Annual Report on Form 10-K filed with the SEC on March 30, 2000; and our Quarterly Reports on Form 10-Q filed with the SEC on May 15, 2000 and August 14, 2000. The following Unaudited Pro Forma Condensed Consolidated Statements of Operations (the "Pro Forma Statements of Operations") for the year ended December 31, 1999 and the six months ended June 30, 2000 give effect to the pro forma transactions described above, as if each had occurred as of January 1, 1999. Pursuant to certain SEC Rules and Regulations, the Pro Forma Financial Statements do not include results of operations, or pro forma adjustments, for nine acquisitions completed in 1999 and three acquisitions completed in 2000 that are not defined herein as the 1999 Pro Forma Acquisitions or shown as a 2000 acquisition. The aggregate pro forma revenues of those 1999 and 2000 acquisitions not included in the pro forma condensed consolidated financial statements were $8.0 million and $1.3 million for the year ended December 31, 1999 and the six months ended June 30, 2000, respectively. In addition, the Pro Forma Statements of Operations do not include the results of operations for acquisitions completed by Pierce Leahy in 1999. Pro forma adjustments are described in the accompanying notes. The Pro Forma Financial Statements do not give effect to estimated annual net cost savings of $15.0 million associated with the Pierce Leahy acquisition. Management expects to achieve this annual level of savings within three years after the merger. Further, the Pro Forma Financial Statements do not reflect any further costs associated with integrating the two companies as it is not practicable to quantify these costs at this time. These costs may be material to Iron Mountain's results of operations. Depending upon management's plans and the nature and timing of the costs, the costs may be accounted for as part of the acquisition accounting, as a post-combination restructuring charge, as operating expenses in the period incurred or as capital expenditures. Furthermore, the Pro Forma Statements of Operations do not give effect to all cost savings or incremental costs that may occur as a result of the integration and consolidation of the 1999 Pro Forma Acquisitions and DSC included in these pro forma financial statements. In June 1999, Iron Mountain decided to sell its information technology staffing business, Arcus Staffing Resources, Inc. ("Arcus Staffing"), which was acquired in January 1998 as part of its acquisition of Arcus Group, Inc. Effective November 1, 1999, Iron Mountain completed the sale of substantially all of the assets of Arcus Staffing. Iron Mountain has accounted for the sale of Arcus Staffing as a discontinued operation. Iron Mountain has accounted for its acquisitions and the related real estate transactions using the purchase method of accounting. The Pro Forma Statements of Operations do not necessarily indicate the actual results of operations that Iron Mountain would have reported if the pro forma transactions described above had occurred as of January 1, 1999, nor do they necessarily indicate the results of future operations. In the opinion of Iron Mountain's management, all adjustments and disclosures necessary to fairly present these pro forma financial statements have been made. On August 14, 2000, Iron Mountain entered into an amended and restated revolving credit agreement (the "Amended Credit Agreement"). The Amended Credit Agreement replaces the Company's prior credit facility, increases the aggregate principal amount available to $750 million and includes two tranches of term debt. Tranches A and B represent term loans to the Company in principal amounts of $150 million and $200 million, respectively. The Tranche A term loan and the revolving credit component of the Amended Credit Agreement mature on January 31, 2005, while the Tranche B term loan matures on February 28, 2006. The interest rate on borrowings under the Amended Credit Agreement varies depending on the Company's choice of base rates, plus an applicable margin. Restrictive covenants under this agreement are similar to those under the Company's prior credit facility. There was no impact to the interest rates under the Amended Credit Agreement, except for the Tranche B term loan, which has an interest rate of .75% higher than the remainder of the facility. The pro forma effect of the additional interest expense, net of commitment fees, that would have been incurred if this Amended Credit Agreement had been in effect since January 1, 1999 is $13.5 million for the year ended December 31, 1999 and $5.7 for the six months ended June 30, 2000. The pro forma increase in net loss is $8.1 million for the year ended December 31, 1999 and $3.4 for the six months ended June 30, 2000, respectively. These adjustments are not reflected in the accompanying pro forma financial statements. The term loans under the Amended Credit Agreement have been used to pay down the revolving credit line, thereby creating an excess cash position. The accompanying pro forma financial statements do not reflect the interest income on the excess cash balance. 1 IRON MOUNTAIN INCORPORATED UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2000 (IN THOUSANDS, EXCEPT PER SHARE DATA) PRO FORMA HISTORICAL ---------------------- PRO FORMA -------------------- PIERCE FOR PIERCE HISTORICAL ----------------------- IRON PIERCE LEAHY LEAHY DATA STORAGE DATA STORAGE IRON MOUNTAIN LEAHY (1) ADJUSTMENTS ACQUISITION CENTER(2) ADJUSTMENTS MOUNTAIN -------- --------- ----------- ---------- ------------ ------------ -------- Revenues: Storage $ 273,384 $ 17,476 $ -- $ 290,860 $ 4,253 $ -- $ 295,113 Service and Storage Material Sales 191,318 12,701 -- 204,019 2,230 -- 206,249 --------- --------- -------- --------- --------- --------- --------- Total Revenues 464,702 30,177 -- 494,879 6,483 -- 501,362 Operating Expenses: Cost of Sales (Excluding Depreciation) 226,431 18,189 (2,363)(E) 242,257 2,544 77(A) 244,878 Selling, General and Administrative 118,181 3,592 2,363 (F) 124,136 2,042 -- 126,178 Depreciation and Amortization 57,947 3,708 258 (G) 61,913 471 418(B) 62,802 Foreign Currency Exchange -- 147 (147)(H) -- -- -- -- Stock Option Compensation Expense 14,939 -- -- 14,939 -- -- 14,939 Merger-related Expenses(3) 4,391 4,438 (3,232)(I) 5,597 -- -- 5,597 --------- --------- -------- --------- --------- --------- --------- Total Operating Expenses 421,889 30,074 (3,121) 448,842 5,057 495 454,394 Operating Income 42,813 103 3,121 46,037 1,426 (495) 46,968 Interest Expense 54,028 4,724 (402)(J) 58,350 111 1,058(C) 59,519 Other Expense, net 4,480 -- 147 (K) 4,627 -- -- 4,627 --------- --------- --------- --------- --------- --------- --------- Income (Loss) Before Provision (Credit) for Income Taxes and Minority Interest (15,695) (4,621) 3,376 (16,940) 1,315 (1,553) (17,178) Provision (Credit) for Income Taxes 18,376 (324) 1,348(L) 19,400 525 (621)(D) 19,304 Minority Interests in losses of subsidiaries (443) -- -- (443) -- -- (443) --------- --------- --------- --------- --------- --------- --------- Income (Loss) from Continuing Operations $ (33,628) $ (4,297) $ 2,028 $(35,897) $ 790 $ (932) $ (36,039) ========= ========= ========= ========= ========= ========= ========= Loss from Continuing Operations per Common Share-Basic and Diluted $(0.66) $(0.66) $(0.66) ========= ========= ========= Weighted Average Common Shares Outstanding-Basic and Diluted 51,292 3,199(M) 54,491 54,491 ========= ========= ========= ========= ========= ========= ========= EBITDA(4) $ 120,090 $ 8,396 $ -- $ 128,486 $ 1,897 $ (77) $ 130,306 ========= ========= ========= ========= ========= ========= ========= - --------- (1) Represents the historical results of operations of Pierce Leahy prior to the acquisition date, February 1, 2000.

See "Overview" in the accompanying notes. The accompanying notes are an integral part of these pro forma financial statements. 4 IRON MOUNTAIN INCORPORATED NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS OVERVIEW DSC ACQUISITION On May 1, 2000, Iron Mountain acquired certain assets and assumed certain liabilities of DSC pursuant to an agreement dated February 18, 2000. The Company acquired substantially all of the operating assets and liabilities of DSC excluding cash, real estate and long-term debt. Iron Mountain did not acquire or assume any assets or liabilities associated with DSC's Pensacola, Florida records management business. The acquisition has been accounted for as a purchase and DSC is included in Iron Mountain's consolidated financial results from the date of acquisition. The accompanying pro forma financial statements do not include adjustments to remove the assets and liabilities or the results of operations related to DSC's Pensacola, Florida records management business as the impact is immaterial. Total consideration was $54.0 million in cash. The Company funded the purchase with borrowings under its revolving credit facility. The assets acquired by Iron Mountain included tangible personal property (consisting primarily of office equipment, furniture and fixtures, motor vehicles and racking) and intangible personal property regularly used in DSC's records management business. Iron Mountain intends to use the acquired property and equipment in the operation of its records management business in the United States. PIERCE LEAHY ACQUISITION On February 1, 2000, Iron Mountain completed its merger with Pierce Leahy for total consideration of approximately $1.1 billion, which consisted of common stock, options to acquire common stock and the assumption of debt. Pierce Leahy was the surviving legal entity and immediately changed its name to Iron Mountain Incorporated. Although Pierce Leahy is the surviving legal entity, Iron Mountain is considered the acquirer for accounting purposes. The merger consideration resulted in the equivalent of a fixed exchange ratio of 1.1 shares of Iron Mountain common stock for each share of Pierce Leahy common stock. The exchange ratio was effected by Pierce Leahy paying, prior to the merger, a stock dividend of one share of Pierce Leahy common stock for each 10 shares then outstanding. The Pierce Leahy common stock was exchanged for shares of Iron Mountain common stock. Each outstanding share of Iron Mountain common stock was converted into one share of common stock of the combined entity. The transaction has been accounted for as a reverse acquisition. The purchase price of Pierce Leahy is based upon the fair value of Pierce Leahy common stock and options to acquire Pierce Leahy common stock, the fair value of the assumed debt on the date that the merger was completed and transaction costs. As the common stock exchange ratio is fixed, the fair value of Pierce Leahy common stock is based upon the stock price on the date the merger was announced. 5 IRON MOUNTAIN INCORPORATED NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) The calculation of the purchase price as of February 1, 2000 is as follows (in millions): Fair Value of Common Stock Issued (1) $ 444.0 Fair Value of Stock Options (2) 25.0 Fair Value of Debt Assumed (3) 584.9 Transaction Costs 4.1 -------- Total Purchase Price $1,058.0 ======== (1) Based on 18,783,813 outstanding shares of Pierce Leahy common stock at February 1, 2000 at a fair value of $23.64 per share. Both the numbers of shares and share price reflect an adjustment for Pierce Leahy's January 2000 10% stock dividend. (2) Based on options to acquire 1,563,566 shares of Pierce Leahy common stock at February 1, 2000 after giving effect to the January 2000 10% stock dividend. (3) Calculated based on the outstanding balances and the quoted market prices when the merger was completed on February 1, 2000. A number of Pierce Leahy shareholders are parties to a certain shareholders' agreement, dated October 20, 1999. This agreement restricts the ability of these shareholders to sell 5.7 million shares of Iron Mountain common stock (after giving effect to the stock dividend) for up to five years after the merger. Iron Mountain may obtain an appraisal to determine the fair value of these restricted shares. Iron Mountain believes that, due to these restrictions, the actual fair value of these restricted shares could be less than the $23.64 per share value used for purposes of calculating the purchase price. Accordingly, Iron Mountain would record a corresponding decrease in equity, goodwill and goodwill amortization from the amounts used in the accompanying pro forma financial statements. If the resale restrictions result in a 10% discount to the fair value of the shares, there would be a reduction of approximately $13 million of equity and goodwill and $0.5 million of goodwill amortization annually. 1999 PRO FORMA ACQUISITIONS In January 1999, Iron Mountain acquired a controlling 50.1% interest in Iron Mountain Europe (f.k.a. Britannia Data Management Limited) for total consideration of $49.3 million, consisting of cash and the capital stock of Arcus Data Security Limited, the Company's existing data security services business in London. In April 1999, Iron Mountain acquired Data Base and related real estate for total consideration of $115.0 million, consisting of cash, assumed debt and common stock. In April 1999, Iron Mountain also acquired FARM for total consideration of $41.5 million in cash. In June 1999, Iron Mountain Europe acquired a controlling 50.1% interest in Memogarde for total consideration of $16.9 million, consisting of cash and assumed debt. The aggregate purchase price for the four remaining 1999 pro forma acquisitions, comprising Midtown, Central File, Iron Mountain Europe's acquisition of Stortext and a 50.1% interest in Sistemas de Archivo Corporativo, was $30.3 million in cash and assumed debt. All of these acquisitions are referred to collectively as the "1999 Pro Forma Acquisitions". IRON MOUNTAIN EUROPE In January 1999, Iron Mountain purchased a controlling 50.1% interest in Iron Mountain Europe for total consideration of $49.3 million, consisting of cash and the capital stock of Arcus Data Security Limited. Iron Mountain Europe has an April 30 fiscal year end. Iron Mountain consolidates Iron Mountain Europe using an October 31 fiscal year end. Accordingly, the Iron Mountain Pro Forma Statements of Operations for the year ended December 31, 1999 include Iron Mountain Europe's results for the year ended October 31, 1999. 6 IRON MOUNTAIN INCORPORATED NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) The financial statements of Iron Mountain Europe, Memogarde and Stortext have been prepared in accordance with U.S. generally accepted accounting principles and have been translated into U.S. dollars in accordance with Statement of Financial Accounting Standards No. 52, "Foreign Currency Translation." The functional currencies of Iron Mountain Europe, Memogarde, and Stortext are Pounds Sterling, French Francs and Pounds Sterling, respectively. Revenues and expenses have been translated into U.S. dollars at the average exchange rate in effect during the period translated. DATA BASE ACQUISITION On April 8, 1999, Iron Mountain acquired Data Base and related real estate for $115.0 million including transaction costs. As part of the total consideration, Iron Mountain issued 1,476,577 shares of common stock with a fair value of $46.0 million. On May 18, 1999, Iron Mountain repurchased all of the shares issued in connection with the Data Base acquisition from the former shareholders of Data Base for $39.5 million, with a portion of the net proceeds from the 1999 equity offering. PURCHASE PRICE ALLOCATION The aggregate consideration paid for the 1999 Pro Forma Acquisitions and the Pierce Leahy and DSC acquisitions was $1.4 billion. The excess of the purchase price over the book value of the net assets acquired for each of the acquisitions was allocated to tangible and intangible assets, based on our estimate of the fair value of the net assets acquired. The following allocation of the aggregate purchase price of DSC and Pierce Leahy is based on the fair value of net assets acquired as of the respective acquisition dates and is subject to adjustment, based on the final determination of the fair value. Management believes that the final allocation of the purchase price of the 1999 Pro Forma Acquisitions will not differ materially from the preliminary estimated amounts. 7 IRON MOUNTAIN INCORPORATED NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (in millions) DSC (1): Current Assets ............................................... $ 2.7 Property, Plant and Equipment ................................ 7.3 Goodwill ..................................................... 42.0 Other Long-term Assets ....................................... 3.0 Current Liabilities ..........................................
