P-5 NOTES TO PRO FORMA FINANCIAL INFORMATION The pro forma financial information is based on the following assumptions and adjustments (in thousands except share and per share amounts): (1) Reflects the repayment of $440 by Atcom of certain outstanding notes payable to officers and financial institutions. (2) Reflects the amounts related to the Atcom transaction: Total purchase consideration and transactions costs are anticipated to be as follows: Amount ------- 2,493,383 common shares of CAIS Internet issued at $12.375 per share (the three-day average closing price of CAIS Internet's common stock surrounding and including the date of the signing and announcement of the Atcom transaction)............................................. $30,856 838,969 options to purchase common shares of CAIS Internet at the estimated fair value..................... 10,131 Estimated transaction costs............................... 1,469 ------- $42,456 The anticipated purchase consideration and transaction costs have been allocated for pro forma purposes as follows: Amount -------- Cash................................... $ 640 Other current and long-term assets..... 528 Property and equipment, net............ 556 Intangibles and goodwill............... 41,720 Accounts payable and accrued expenses.. (984) Other current liabilities.............. (4) -------- $42,456 The above purchase price allocation is preliminary and may change upon final determination of the fair value of net assets acquired. The Company has not specifically identified amounts to assign to other intangibles including but not limited to existing technology, existing workforce, and installed customer base. Changes in the amounts allocated to such assets could result in changes to the amount of goodwill recorded. An amortization period of three years has been selected and utilized in the pro forma financial information for goodwill and other identifiable intangible assets, which is expected in all material respects to be representative of the amortization expense that will result from the ultimate allocation to the specific intangible assets. P-6 (3) Reflects the conversion of Atcom Series A, B, and C Convertible Preferred Stock and Series D Redeemable Convertible Preferred Stock into Atcom common stock prior to the conversion into CAIS Internet common stock, and the elimination of equity accounts of Atcom, upon consolidation. (4) Reflects the amortization over a three-year life of the excess of purchase price of Atcom over the fair market value of net assets acquired. (5) Reflects common shares issued in connection with the Atcom transaction. (6) Reflects the elimination of transactions between CAIS Internet and Atcom. P-7
