UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial statements present the effect of the pending acquisition of CheckFree Corporation (“CheckFree”) by Fiserv, Inc. (“Fiserv”) for approximately $4.4 billion payable in cash at closing and the issuance of long-term debt by Fiserv to fund the acquisition. In addition, the following unaudited pro forma condensed combined financial statements present the effect of our pending dispositions of certain health businesses (“Fiserv Health”) for approximately $775 million payable in cash at closing and Fiserv Investment Support Services (“Fiserv ISS”), in two transactions for approximately $355 million payable in cash at closing before payment of taxes and transaction expenses. Fiserv anticipates that the acquisition of CheckFree will close by the end of 2007. Fiserv expects the disposition of Fiserv Health to be completed by the end of 2007 or in the first quarter of 2008. Fiserv expects one of the transactions involving the disposition of Fiserv ISS to close in the fourth quarter of 2007 and the other to close in the first quarter of 2008.

Fiserv ISS has been classified as held for sale and the related results of discontinued operations are excluded from Fiserv’s historical results in the unaudited pro forma condensed combined statements of income. The unaudited pro forma condensed combined statements of income presented do not reflect the anticipated net gain resulting from the sale of Fiserv ISS.

These unaudited pro forma condensed combined financial statements should be read in conjunction with the historical consolidated financial statements, including the notes thereto, of Fiserv and CheckFree, which are included in the annual and quarterly reports that we and CheckFree have filed with the SEC or as exhibits to our Current Report on Form 8-K to which these unaudited pro forma condensed financial statements are an exhibit.

The following unaudited pro forma condensed combined statements of income for the nine months ended September 30, 2007 and the year ended December 31, 2006 give effect to the CheckFree acquisition as if it had occurred at the beginning of each period and the sale of Fiserv Health as a discontinued operation and reflect a reduction of interest expense resulting from the use of the anticipated sale proceeds from Fiserv ISS and Fiserv Health primarily for the repayment of long-term debt. The following unaudited pro forma condensed combined balance sheet as of September 30, 2007, gives effect to the CheckFree acquisition, using the purchase method of accounting, and the sale of Fiserv Health and Fiserv ISS as if these transactions had occurred on September 30, 2007. The unaudited pro forma adjustments are based on available information and assumptions that we believe are reasonable under the circumstances, and actual results could differ materially from anticipated results.

Because we maintain a calendar fiscal year and CheckFree’s fiscal year ends on June 30, we have combined CheckFree’s results from different fiscal periods for purposes of this pro forma presentation, as described in footnote (a) to the accompanying unaudited pro forma financial statements. CheckFree’s historical statements of income include the results of operations for CheckFree’s acquisitions of Corillian Corporation (“Corillian”) in May 2007 and Carreker Corporation (“Carreker”) in April 2007 since the dates of acquisition. The unaudited pro forma condensed combined statements of income were not adjusted for the historical results of Corillian and Carreker prior to the effective date of acquisition because these acquisitions are not significant under Rule 3-05 of SEC Regulation S-X and our management does not believe they are material. In separate transactions, CheckFree acquired Corillian and Carreker for $245 million and $206 million in cash, respectively.

The following unaudited pro forma condensed combined statements of income for the years ended December 31, 2005 and 2004 give effect to the sale of Fiserv Health as a discontinued operation for those respective periods and do not reflect any reduction of interest expense resulting from the use of the anticipated sale proceeds from Fiserv ISS and Fiserv Health for the repayment of long-term debt.

The unaudited pro forma financial statements are presented for illustration purposes only, in accordance with the assumptions set forth below, include various estimates and are not necessarily indicative of the operating results or financial position that would have occurred had the transactions been completed at the assumed dates or of the operating results or financial position of the combined enterprise in the future. The unaudited pro forma financial statements do not reflect any adjustments to conform accounting practices, other than those mentioned in the notes thereto, or to reflect any cost savings or other synergies anticipated as a result of the acquisition, the effect of asset dispositions, if any, or any transaction related expenses.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

(a) The unaudited pro forma condensed combined statements of income which reflect CheckFree’s results of operations for the year ended December 31, 2006 have been calculated as (i) the respective amounts for the fiscal year ended June 30, 2007, (ii) the subtraction of the respective amounts for the quarters ended March 31, 2007 and June 30, 2007, and (iii) the addition of the respective amounts for the quarters ended March 31, 2006 and June 30, 2006. CheckFree’s results of operations for the nine months ended September 30, 2007 have been calculated as the combination of the respective amounts for the quarters ended March 31, 2007, June 30, 2007 and September 30, 2007. Certain reclassifications have been made to the presentation of the historical financial statements of CheckFree in order to conform to the presentation of Fiserv’s historical financial statements. These reclassifications had no impact on CheckFree’s historical total revenue or income from continuing operations.

For the nine months ended September 30, 2007:

For the year ended December 31, 2006:

Certain reclassifications have been made to the presentation of the historical balance sheet of CheckFree to conform to the presentation of Fiserv’s balance sheet as of September 30, 2007. These reclassifications, listed below, had no impact on CheckFree’s historical total assets, liabilities, or stockholders’ equity.

(b) The unaudited pro forma condensed combined statements of income presented herein reflect Fiserv Health as discontinued operations as a result of its anticipated sale and do not reflect the anticipated gain resulting from the sale of Fiserv Health. A reduction in interest expense resulting from the use of anticipated sale proceeds primarily for the repayment of long-term debt is reflected in the nine months ended September 30, 2007 and year ended December 31, 2006, but not in the years ended December 31, 2005 and 2004.

(c) To record an elimination adjustment for transactions involving the purchase and sale of services between Fiserv and CheckFree. These adjustments totaled $8.0 million and $7.8 million for the year ended December 31, 2006 and nine months ended September 30, 2007, respectively, and were recorded as reductions of processing and services revenue and cost of processing and services.

(d) To record an increase in amortization expense related to the recording of the fair value of acquired identifiable intangible assets, amortized over their estimated remaining useful lives. This preliminary pro forma adjustment has been calculated as the estimated annual amortization minus CheckFree’s historical amortization expense, and amortization of developed technology has been allocated to cost of processing and services and amortization of customer relationships has been allocated to selling, general and administrative expenses as follows (in thousands):

The pro forma adjustment for amortization expense is based on the preliminary purchase price allocation discussed in footnote (l). Changes to the preliminary purchase price allocation including the finalization of appraisals of acquired assets and the finalization of estimated useful lives will result in a change to the pro forma adjustment for amortization expense. There can be no assurance that such finalizations will not result in material changes. Goodwill resulting from the acquisition is not amortized in accordance with the provisions of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”).

(e) To record pro forma interest expense on debt incurred to acquire CheckFree. The expected borrowings incurred to fund the acquisition include the financing of $30 million of debt issuance costs and $20 million of acquisition fees and expenses which primarily relate to legal, financial and other professional fees and expenses. The amount of incremental interest expense, calculated below, is based on the expected interest rates on the long-term financing obtained prior to closing the acquisition. The expected weighted average interest rate of 6.4% includes amortization of debt issuance costs over the life of the related debt, ranging from 5 to 10 years. This rate is a preliminary estimate and may differ from the actual interest rate available to the Company on the borrowing date. The pro forma condensed combined statements of income do not assume reductions to interest expense due to principal repayments of the initial borrowings or changes in interest rates. A change in the expected interest rate of 0.125% would impact pro forma operating income by approximately $5.6 million on an annual basis. The pro forma adjustment for interest expense is calculated as follows (in thousands):

(f) To record the reduction in incremental interest expense due to the anticipated $750 million paydown of the existing revolving credit facility and other debt with the anticipated net proceeds from the dispositions of Fiserv ISS and Fiserv Health and the excess $50 million from the new term loan facility borrowings discussed in footnote (j). Based on assumed interest rates of 5.8% and 5.3%, the reduction of interest expense due to the $750 million debt paydown is $32.6 million and $39.8 million for the nine months ended September 30, 2007 and year ended December 31, 2006, respectively.

(g) To record the income tax provision on the pro forma adjustments based on the applicable statutory federal and state income tax rates.

(h) The unaudited pro forma condensed combined balance sheet reflects the sale of Fiserv Health. The pro forma adjustment to cash and cash equivalents represents the preliminary net proceeds of $455 million from the sale less cash included in the businesses to be sold of $29 million and the pro forma adjustment to shareholders’ equity represents the preliminary net gain of $97 million. The unaudited pro forma condensed combined balance sheet does not reflect the estimated final adjustments for changes in net working capital for the disposition of Fiserv Health, which we expect to increase the net proceeds by approximately $20 million by the time of closing resulting in total anticipated net proceeds of $475 million.

(i) The unaudited pro forma condensed combined balance sheet reflects the sale of Fiserv ISS. Preliminary net proceeds from the sale of $250 million are reflected in cash and cash equivalents and the preliminary net gain of $80 million is reflected in shareholders’ equity. These adjustments exclude any anticipated proceeds from contingent cash consideration of up to $100 million based on achievement of revenue targets over the twelve months subsequent to closing.

(j) To record debt incurred to acquire CheckFree of $4.5 billion, which includes the financing of $30 million of debt issuance costs and $20 million of acquisition fees and expenses, which are discussed in footnote (e) above, and $50 million to be used for the repayment of debt.

(k) To reflect the use of a portion of the anticipated net proceeds from the disposition of Fiserv ISS and Fiserv Health and the excess $50 million from the new term loan facility borrowings discussed in footnote (j) to repay $750 million of the existing revolving credit facility and other debt.

(l) To adjust the historical assets and liabilities of CheckFree, to record goodwill, intangible assets and deferred income taxes associated with the acquisition and to reverse CheckFree’s historical goodwill and

9

intangible assets. The pro forma adjustments to intangible assets and goodwill represent the difference between the preliminary allocation of purchase price and the amounts on CheckFree’s balance sheet at September 30, 2007. The preliminary allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated relative fair values is as follows (in thousands):

The above preliminary purchase price and the preliminary allocation of purchase price are preliminary because the acquisition has not yet been completed. The preliminary allocation of purchase price is based on a preliminary assessment of the fair values of the assets to be acquired and liabilities to be assumed in the acquisition and does not reflect final appraisals of assets to be acquired or final evaluation of all liabilities to be assumed in the acquisition. Goodwill is generated to the extent that the purchase price exceeds the fair value of the net assets acquired. The preliminary assessment of fair value resulted in goodwill of $2.85 billion, which will be subject to periodic impairment testing, in accordance with SFAS 142. The preliminary assessment of the fair values of CheckFree’s intangible assets are based on projections of expected future net cash flows, discounted to present value. Other assets and liabilities are valued at their historical book value. These and other preliminary estimates will change as additional information becomes available and is assessed by Fiserv after the closing of the acquisition.

(m) To eliminate CheckFree’s historical shareholders’ equity.
