                 CHECKFREE HOLDINGS CORPORATION AND SUBSIDIARIES
     NOTES TO INTERIM UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
               FOR THE SIX MONTHS ENDED DECEMBER 31, 1997 AND 1996


         1. The accompanying condensed consolidated financial statements and
notes thereto have been prepared in accordance with the rules and regulations of
the Securities and Exchange Commission for Form 10-Q and include all of the
information and disclosures required by generally accepted accounting principles
for interim financial reporting. The results of operations for the six months
ended December 31, 1997 and 1996 are not necessarily indicative of the results
for the full year.

                  These financial statements should be read in conjunction with
the financial statements, accounting policies and financial notes thereto
included in the Company's Annual Report filed with the Securities and Exchange
Commission on Form 10-K. In the opinion of management, the accompanying
unaudited condensed consolidated financial statements reflect all adjustments
(consisting only of normal recurring adjustments) which are necessary for a fair
representation of financial results for the interim periods presented.

         2. Basic earnings (loss) per common share amounts were computed by
dividing income (loss) available to common shareholders by the weighted average
number of common shares outstanding. Diluted per-common-share amounts assume the
issuance of common stock for all potentially dilutive equivalent shares
outstanding. Due to anti dilution provisions of FAS 128, diluted
per-common-share amounts are consistent with basic per-common-share amounts in
loss periods. The following table reconciles differences in income and shares
outstanding between basic and diluted for the periods indicated.

         3. During the quarter ended September 30, 1997, the Company reissued
78,257 shares of treasury stock to fund its 401(k) match, which accrued during
the year ended June 30, 1997.

         4. On August 29, 1997, the Company sold certain software and related
assets for $33.5 million. The gain from the sale of approximately $28.4 million
has enabled the Company to eliminate a deferred tax benefit valuation allowance
of $6.0 million in the quarter ended September 30, 1997. The deferred tax
benefit valuation allowance reduction was first applied against the balance of
goodwill and remaining amounts were ratably applied against remaining intangible
asset balances resulting from the Servantis acquisition.

         5. The Company periodically assesses the likelihood of recovering the
cost of long-lived assets based on its expectation of future profitability and
undiscounted cash flow of the related operations. These factors, along with
management's plans with respect to the operations, are considered in assessing
the recoverability of property and purchased intangibles. During the quarter
ended September 30, 1997, the Company recorded a writedown of approximately $3.0
million for certain equipment and capitalized costs and reflected this in net
gain on dispositions of assets.

         6. On October 3, 1997, the Company acquired the net assets of Advanced
Mortgage Technologies, Inc. ("AMTI") for cash of $1.0 million. The acquisition
was treated as a purchase for accounting purposes, and accordingly, the assets
and liabilities were recorded based on their fair values at the date of the
acquisition. Of the total purchase price, $0.2 million was allocated to goodwill
and $0.1 million to other identifiable intangible assets. Additionally, $0.7
million was allocated to in-process research and development, which was charged
to operations at the time of the acquisition. AMTI provides mortgage default
management software.

         7. On October 29, 1997, the Company announced a ten year processing
agreement with a strategic partner and executed the definitive agreements on
January 8, 1998. Under the terms of the agreements, the strategic partner will
acquire 10-year warrants exercisable at $20 15/16 per share for 10 million
shares of the Company's common stock. Three million warrants vest upon execution
of a processing outsourcing agreement and the Company expects to incur a
non-cash charge of between $30 million and $50 million dependent upon the market
value of the stock on the execution date, which is expected to occur before the
end of the fiscal year. The remaining seven million warrants are to vest upon
achievement of specific performance targets set forth in the agreement. Any
shares acquired by the strategic partner upon exercise of the warrants will be
subject to certain transfer and other restrictions.

         8. In November 1997, the Company paid $10 million as the final
installment of the exclusivity arrangement related to the purchase of Intuit
Services Corporation ("ISC") which occurred in January 1997. Additionally, under
the terms of the purchase agreement the Company received $8.9 million from the
seller as a purchase price adjustment, which resulted in a corresponding
reduction in goodwill effective October 1, 1997.

         9. Certain amounts in the June 30, 1997 balance sheet have been
reclassified to conform to the December 31, 1997 presentation. In addition,
certain amounts in the condensed consolidated statements of operations for the
six months ended December 31, 1996 have been reclassified to conform with
December 31, 1997 presentation.

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

OVERVIEW

         The business was founded in 1981, and following a number of
acquisitions and divestitures reorganized its corporate structure on December
22, 1997. CheckFree Holdings Corporation (the "Company") is the parent
corporation of CheckFree Corporation, the principal operating company of the
business. In connection with the restructuring, holders of common stock of
CheckFree Corporation became holders of an identical number of shares of common
stock of CheckFree Holdings Corporation. The restructuring was effected by a
merger conducted pursuant to Section 251(g) of the Delaware General Corporation
Law, which provides for the formation of a holding company structure without a
vote of the stockholders of the Company. For more detailed information
concerning the restructuring, please refer to the Company's Form 8-K filed on
December 30, 1997.

         The Company is the leading provider of electronic commerce services,
software and related products for over 2.2 million consumers, 1,000 businesses
and 850 financial institutions. The Company designs, develops and markets
services that enable its customers to make electronic payments and collections,
automate paper-based recurring financial transactions and conduct secure
transactions on the Internet. As a result of significant acquisitions in 1996
and 1997, the Company now operates in three business segments: Electronic
Commerce, Software, and Investment Services. The Company's electronic
transaction processing services, software, and related products are targeted to
financial institutions, businesses, institutional investment portfolio managers,
and their customers.

         The Company's focus has turned from integration of acquisitions to
evolution of the electronic commerce marketplace and quality improvement
combined with greater efficiency. The Company is driving to grow the
profitability of the business by continuing to grow revenue and realizing the
economies of scale and leverage inherent in its business model as well as
continuing to improve costs primarily in remittance, customer care and data
processing. With continued sales and marketing efforts geared toward promoting
its new electronic commerce offerings, especially electronic bill presentment,
existing and enhanced investment and software product and service offerings, and
the continued growth in subscribers resulting from the continued acceptance in
the marketplace of electronic commerce services, the Company expects revenue to
continue to improve. Improvements in remittance and customer care costs and
quality will primarily be driven by an increased percentage of electronic versus
paper transactions processed on certain platforms. Improvements in data
processing costs and quality are addressed by the Company's Genesis project,
which is designed to provide a single, state of the art processing platform and
to promote customer care efficiency. Genesis will also contribute to an
increased percentage of transactions being effected electronically.

         The Company expects that these efforts will allow it to defend and
extend its leading position in the rapidly growing electronic commerce market.
Barring any unforeseen circumstances, this trend is expected to continue in the
near future. There can be no assurance, however, that the Company will be able
to successfully compete against current or future competitors or that the
competitive pressures faced by the Company will not have a material adverse
effect on its business, operating results, and financial condition.

RESULTS OF OPERATIONS

         The following table sets forth as percentages of total operating
revenues certain consolidated statements of operations' data:

</TABLE>


         Revenue increased 47% from $38.5 million to $56.5 million for the three
months ended December 31, 1996 and 1997, respectively and 53% from $71.2 million
to $108.6 million for the six months ended December 31, 1996 and 1997,
respectively. The increases in revenue are due primarily to internal growth in
the Company's electronic commerce and investment services businesses, additional
revenue contributed from the purchase of ISC, which was completed in January of
1997, and the elimination of purchase profits relating to the February 1996
Servantis acquisition amounting to $1.7 million and $7.7 million in the quarter
and six months ended December 31, 1996, respectively. On a pro forma basis, year
to date revenue increased 34% over the prior year driven by internal growth of
56% in the electronic commerce business, 37% in the investment services business
and 4% in the software business. Pro forma revenue increased 34% on a quarter
over quarter basis as a result of growth of 56% in electronic commerce, 41% in
investment services, and 2% in software. Pro forma results are based on prior
year adjusted for the acquisitions noted above and divestitures of the Company's
securities business which was sold in October 1996, the credit card processing
business which was sold in March 1997, and the credit management business which
was sold in August 1997. Pro forma growth rates in the electronic commerce
business unit is driven primarily by an increase in subscribers from
approximately 1.3 million at December 31, 1996 (includes ISC subscribers) to 2.2
million at December 31, 1997. Investment services revenue growth is due
primarily to an increase in portfolios managed from approximately 302,000 at
December 31, 1996 to over 400,000 at December 31, 1997. Growth in software is
primarily the result of maintenance and services generated from new license
sales in 1997 and 1996.

         Processing and servicing revenue increased by 104% from $35.7 million
to $72.9 million in the six month periods ending December 31, 1996 and 1997,
respectively, and by 116% from $17.8 million to $38.4 million in the quarter
ending December 31, 1996 and 1997, respectively. On a pro forma basis,
processing and servicing revenue increased by 52% from $48.1 million to $72.9
million in the six months ending December 31, 1996 and 1997, respectively and by
55% from $24.8 million to $38.4 million in the quarter ending December 31, 1996
and 1997, respectively. This growth was due to the increase in subscribers in
the Electronic Commerce segment and the increase in portfolios managed in the
Investment Services segment mentioned above.

         Merchant discount revenue decreased from $6.6 million to $0 in the six
months ended December 31, 1996 and 1997, respectively and decreased from $3.4
million to $0 in the three months ended December 31, 1996 and 1997,
respectively, due to the sale of the Company's credit card processing business
in March 1997.

         License revenue remained constant at $13.5 million versus $13.3 million
for the six months ended December 31, 1996 and 1997, respectively. On a pro
forma basis, excluding the elimination of purchased profits and adjusting for
the sales of the Company's securities business and credit management business
license revenue declined by $200,000 from $13.5 million to $13.3 million on a
year over year basis. For the quarter ended December 31, 1996 and 1997, license
revenue declined from $8.6 million to $7.5 million, respectively. On a pro forma
basis, license revenue declined by $200,000 from $7.7 million to $7.5 million on
a quarter over quarter basis. The consistent results are the due to an unusually
strong second quarter in 1996.

         Maintenance revenue increased from $8.4 million to $13.3 million for
the six months ended December 31, 1996 and 1997, respectively and from $4.8
million to $6.4 million for the three months ended December 31, 1996 and 1997,
respectively. On a pro forma basis, excluding the elimination of purchased
profits and adjusting for the sales of the securities business and the credit
management business, maintenance revenue increased by 10% from $12.1 million to
$13.3 million in the six month periods ending December 31, 1996 and 1997,
respectively, and by 8% from $5.9 million to $6.4 million quarter over quarter.
Customer retention rates in the mid to upper 80% range are offset by an average
maintenance price increase of approximately 7% as well as first year maintenance
from new license sales.

         Other revenue, consisting mainly of consulting fees, increased from
$7.0 million to $9.1 million in the six months ended December 31, 1996 and 1997,
respectively, and from $4.0 million to $4.2 million for the three months ended
December 31, 1996 and 1997, respectively. On a pro forma basis, excluding the
elimination of purchased profits and adjusting for the sales of the securities
and credit management businesses, other revenue increased from $7.3 million to
$9.1 million for the six months ended December 31, 1996 and 1997, respectively,
and from $3.8 million to $4.2 million for the three months ended December 31,
1996 and 1997, respectively. Year to date and quarterly increases are due
primarily to increased implementations in all business segments.

         The cost of processing, servicing and support was $44.8 million and
$60.1 million or 63.0% and 55.4% of total revenue for the six months ended
December 31, 1996 and 1997, respectively. These same costs were $23.0 million
and $30.8 million or 59.8% and 54.5% of total revenue for the three months ended
December 31, 1996 and 1997, respectively. Cost of processing as a percentage of
servicing only revenue (all revenue except license) and net of purchased profits
of $6.3 million in the 1996 servicing revenue, was 70.0% and 63.1% for the six
months ended December 31, 1996 and 1997, respectively. For the three months
ended December 31, 1996 and 1997, the cost of processing as a percentage of
servicing only revenue and net of purchased profits of $1.7 million in the 1996
servicing revenue was 72.9% and 62.8%, respectively. The efficiency
improvements, both on a year over year and quarter over quarter basis, are due
primarily to an increase in the percentage of electronic transactions versus
paper transactions which resulted in lower customer care and material costs per
transaction and through significant economies of scale and leverage inherent in
the business model of the electronic commerce segment.

         Research and development costs were $14.0 million and $16.8 million or
19.6% and 15.5% of total revenue for the six months ended December 31, 1996 and
1997, respectively. Excluding purchased profits, research and development costs
were 17.7% and 15.5% for the same six month periods. These same costs were $7.0
million and $8.7 million or 18.2% and 15.4% of total revenue for the three
months ended December 31, 1996 and 1997, respectively. Excluding purchased
profits, research and development costs were 18.1% and 15.4% for the same three
month periods. The dollar increase of $2.8 million in the year over year period
and $1.7 million in the quarter over quarter period are primarily the result of
added resources for Genesis development. Other research and development spending
on existing products and services has remained fairly consistent from year to
year resulting in the decrease of R&D as a percentage of revenue. The Company
did not capitalize any development cost in the six month period or three month
period ended December 31, 1996 and 1997, respectively.

         Sales and marketing costs were $12.4 million and $15.3 million or 17.4%
and 14.1% of total revenue for the six months ended December 31, 1996 and 1997,
respectively. Excluding purchased profits, sales and marketing costs were 15.7%
and 14.1% of total revenue for the same respective periods. Sales and marketing
costs were $6.8 million

                                      -10-

and $7.9 million or 17.8% and 13.9% of total revenue for the three months ended
December 31, 1996 and 1997, respectively. Excluding purchased profits, sales and
marketing costs were 17.7% and 13.9% for the same respective periods. The
absolute increase in the cost in this area is due primarily to the addition of
approximately 20 sales and marketing associates year over year in support of
efforts to expand the number of merchants accepting electronic versus paper
remittances but the cost as a percentage of revenue has declined due to
economies of scale and leverage inherent in the Company's business model.

         General and administrative expenses were $9.6 million and $10.5 million
or 13.5% and 9.7% of total revenue for the six months ended December 31, 1996
and 1997, respectively. Excluding purchased profits, general and administrative
costs were 12.2% and 9.7% of total revenue for the same six month periods.
General and administrative expenses were $4.6 million and $5.1 million or 11.8%
and 9.0% of total revenue for the three months ended December 31, 1996 and 1997,
respectively. Excluding purchased profits, general and administrative expenses
were 11.8% and 9.0% for the same three month periods. The Company's general and
administrative costs have decreased as a percent of revenue on a year over year
and quarter over quarter basis due to its ability to leverage corporate support
services as revenue continues to grow.

         Depreciation and amortization expenses increased by $1.8 million from
$11.3 million for the six months ended December 31, 1996 to $13.1 million for
the six months ended December 31, 1997. Similarly, depreciation and amortization
expenses increased by $ .3 million from $5.8 million for the three months ended
December 31, 1996 to $6.1 million for the three months ended December 31, 1997.
Purchases of property, plant and equipment required for Genesis development and
in support of the growth of the business, combined with tangible and intangible
asset additions resulting from the purchase of ISC in January 1997 are offset
largely by reductions in tangible and intangible assets resulting from the sale
of the sale of the securities business in October 1996 and the credit management
business in August 1997.

         The $.7 million charge for in process research and development in the
six month and three month periods ending December 31, 1997 resulted from the
purchase of AMTI in October 1997.

         Exclusivity amortization of $2.9 million in the six month period ended
December 31, 1997 was the final amortization expense related to the exclusivity
arrangement the Company entered into with Intuit in conjunction with the
purchase of ISC in January 1997.

         The net gain on dispositions of assets in the six months ended December
31, 1997 includes two items. In August 1997 the company sold certain software
and related assets, which resulted in a gain on the sale of approximately $28.4
million. Additionally, the Company recorded a charge of approximately $3.0
million related to certain equipment and capitalized costs, as it was determined
that the book value of these assets exceeded their net realizable value.

         Net interest income increased by approximately 22% from $.9 million in
the six months ended December 31, 1996 to $1.1 million in the six months ended
December 31, 1997. On a quarter over quarter basis net interest income increased
approximately 60% from $.5 million for the three months ended December 31, 1996
to $.8 million for the three months ended December 31, 1997. On a year over year
basis, the Company's average cash and invested assets balance increased by
approximately 23% from $39.7 million during the six months ended December 31,
1996 to $48.9 million during the six months ended December 31, 1997 resulting
mainly in the increased net interest income. On a quarter over quarter basis,
the Company's average cash and invested assets balance increased by 83% from
$34.2 million during the three months ended December 31, 1996 to $62.7 million
resulting mainly in the increased net interest income for the period. Cash and
invested assets have improved in 1997 due primarily to the sale of the credit
management business that resulted in cash proceeds of $33.5 million in August of
this year.

         The Company recorded an income tax benefit of $7.0 million and income
tax expense of $7.5 million in the six-month period ended December 31, 1996 and
1997, respectively. The effective tax rates for the respective six-month periods
were (35.0%) and 48.0%. For the three months ended December 31, 1996 and 1997
the Company recorded an income tax benefit of $2.9 million and $.3 million,
respectively. The effective tax rates for the respective three-month periods
were (35.0%) and (16.0%). The reported rates differ from the blended statutory
rate of 40% primarily due to certain goodwill amortization and other expenses,
which are not deductible for federal income tax purposes. Non

                                      -11-

deductible goodwill and other expenses totaled approximately $2.7 million and
$1.8 million in the six month and three month periods ended December 31, 1997,
respectively.

          Revenue in the electronic commerce business unit increased by $15.6
million or 91% from $17.1 million to $32.7 million for the three months ended
December 31, 1996 and 1997, respectively, and by $29.4 million or 87% from $33.6
million to $63.0 million for the six months ended December 31, 1996 and 1997,
respectively due primarily to internal growth and the acquisition of ISC in
January 1997. This growth was partially offset by the Company's credit card
processing business, which contributed $4.0 million and $8.0 million in the
three and six month periods ended December 31, 1996, respectively. On a pro
forma basis, assuming ISC results are included in and the credit card processing
business is excluded from the quarter and year to date results, revenue
increased 56% quarter over quarter and 56% year over year driven by growth in
subscribers from approximately 1.3 million at December 31, 1996 to 2.2 million
at December 31, 1997. Operating losses in the electronic commerce segment
decreased from $5.2 in the three

                                      -12-

months ended December 31, 1996 to $.2 million for the same period in 1997 and
decreased from $9.1 million in the six months ended December 31, 1996 to $1.1
million for the same period in 1997. On a pro forma basis, the operating loss
decreased from $9.5 million to $.2 million in the three months ended December
31, 1996 and 1997, respectively and from $19.1 million to $1.1 million in the
six months ended December 31, 1996 and 1997, respectively. Favorable operating
results are primarily due to the continued revenue growth as well as continued
efficiency improvements in remittance and customer care costs, reduction in
costs from the integration of the ISC acquisition and significant economies of
scale and leverage inherent in the segment's business model. Cost improvements
in customer care and remittance are the result of growth in electronic payment
percentage year over year.

         Software revenue increased from $16.2 million for the three months
ended December 31, 1996 to $16.5 million for the same period in 1997 and from
$27.4 million for the six month period ended December 31, 1996 to $31.7 million
for the same period in 1997. On a pro forma basis, excluding the effect of
purchased profits and adjusting prior year to eliminate results contributed by
the credit management business, revenue increased by 2% on a quarter over
quarter basis and by 4% on a year over year basis. Revenue growth is primarily
the result of maintenance and services generated from new license sales in 1996
and 1997. Reported operating results remained fairly consistent from a profit of
$2.0 million for the three months ended December 31, 1996 to $1.8 million for
the same period in 1997 and improved from a loss of $1.5 million for the six
month period ended December 31, 1996 to a profit of $2.0 for the same period in
1997. On a pro forma basis, operating income decreased from $2.4 million to $1.8
million for the quarter ended December 31, 1996 and 1997, respectively and from
$3.4 million to $2.0 million for the six months ended December 31, 1996 and
1997, respectively.

         Revenue in investment services has increased by 41% from $5.2 million
to $7.3 million in the three months ended December 31, 1996 and 1997,
respectively, and by 37% from $10.2 million to $14.0 million in the six months
ended December 31, 1996 and 1997, respectively. This improvement is due to a
corresponding increase in portfolios managed from approximately 302,000 at
December 31, 1996 to over 400,000 at December 31, 1997. Operating income has
improved from $0.3 million to $1.4 million in the quarter ended December 31,
1996 and 1997, respectively and from $1.1 million to $2.4 million in the six
months ended December 31, 1996 and 1997, respectively. Operating results have
improved due to the leverage and economies of scale inherent in the segment's
business model.

         The corporate segment represents charges the Company's human resources,
legal, finance and accounting functions and various other unallocated overhead
charges. Corporate incurred an improvement in operating costs from $5.9 million
to $5.0 million on a quarter over quarter basis and from $11.4 million to $10.7
million on a year over year basis. The improvements are due to successful
efforts to assimilate the various acquisitions and leverage the existing
infrastructure in light of overall growth in the business.

         Exclusivity amortization represents amortization of charges capitalized
in conjunction with the exclusivity arrangement with Intuit, entered into with
the acquisition of ISC in January 1997. The charge of $2.9 million in the
quarter ended September 30, 1997 is the final charge in this regard as the life
of the exclusivity arrangement has expired.

         In process research and development costs of $0.7 million in the
quarter ended December 31, 1997 relates to the purchase of AMTI in October 1997.

         The net gain on dispositions of assets amounting to $25.4 million in
the six months ended December 31, 1997 includes two items. In August 1997 the
Company sold certain software and related assets, which resulted in a gain on
the sale of approximately $28.4 million. Additionally, the Company recorded a
charge of approximately $3.0 million related to certain equipment and
capitalized costs, as it was determined that the book value of these assets
exceeded their net realizable value.

YEAR 2000

         The Company has several projects currently in progress addressing the
Year 2000 computer programming issue related to products available for sale and
to software programs for internal use. In the Electronic Commerce segment the
Company anticipates it will incur approximately $1.5 million in costs to correct
outstanding issues in the various processing programs, the majority of which are
contemplated in the Genesis program. In the Software segment, work has been
completed on approximately 75% of the products to be modified and it will
require an estimated $1.4 million in costs

                                      -13-

<PAGE>   14



to complete the remaining work. The Investment Services segment expects to incur
approximately $500,000 to correct existing issues. For internal purposes the
Company utilizes a small number of non-Year 2000 compliant computer programs and
is currently evaluating whether to upgrade or replace the systems. In either
case, the cost to upgrade is not expected to exceed $300,000 at this time.
Failure by the Company, its customers or vendors to adequately address the Year
2000 issue in a timely manner could result in a material financial risk.
Accordingly, the Company plans to adequately address all Year 2000 issues before
problems materialize and believes that all such costs are adequately provided
for in its 1998 and 1999 business plans.

LIQUIDITY AND CAPITAL RESOURCES

         For the six months ended December 31, 1997, the Company's operating
activities provided cash of $.7 million. During the six month period the company
received $33.5 million from the sale of the credit management business and paid
$1.0 million for the purchase of AMTI. In conjunction with the purchase of ISC,
the Company paid the final installment of $10 million in November 1997, offset
by receipt of $8.9 million for a purchase price adjustment per the terms of the
purchase agreement. An additional $8.7 million has been invested in property
additions primarily for computer related equipment and facilities and $5.0
million on the net purchase of investments. From a financing perspective, the
Company received approximately $1.6 million from the exercise of stock options
and the employee stock purchase plan and made payments of $.4 million on capital
lease obligations. As a result, at December 31, 1997 the Company's cash and cash
equivalents were $51.8 million, a net increase of $19.7 million from June 30,
1997 and $.1 million from September 30, 1997. Additionally, the Company's
invested assets increased from $4.4 million at June 30, 1997 to $9.5 million at
December 31, 1998. As a result of the increase in cash and invested assets, the
Company's current ratio has improved from 1.3 to 2.3 and the related working
capital has improved from $19.4 million to $63.4 million from June 30, 1997 to
December 31, 1997, respectively.

         The Company expects to break even for the three months ending March 31,
1998 and believes the existing cash, cash equivalents and investments will be
sufficient to meet presently anticipated operating, working capital and capital
expenditure requirements for the foreseeable future. To the extent that
additional capital resources may be needed, the Company has access to a $20
million line of credit.

INFLATION

         The Company believes the effects of inflation have not had a
significant impact on the Company's results of operations.

                           PART II. OTHER INFORMATION


ITEM 2.  CHANGES IN SECURITIES.

         On December 22, 1997, CheckFree Corporation, a Delaware corporation,
adopted a holding company form of organizational structure whereby Checkfree
became the successor issuer to CheckFree Corporation. As a result of the
reorganization, CheckFree Corporation became a wholly owned subsidiary of
CheckFree.

         In connection with the restructuring, holders of common stock of
CheckFree Corporation became holders of an identical number of shares of common
stock of CheckFree Holdings Corporation. The restructuring was effected by a
merger conducted pursuant to Section 251(g) of the Delaware General Corporation
Law, which provides for the formation of a holding company structure without a
vote of the stockholders of the Company. For more detailed information
concerning the restructuring, please refer to the Company's Form 8-K filed on
December 30, 1997.
