agreement and the transactions contemplated by that agreement. You are being
asked only to approve the issuance of an aggregate of not less than 10 million
and up to 20 million shares of our common stock in connection with the
transactions contemplated in the strategic agreement. It is a condition to the

issuance. WE URGE YOU TO READ THESE MATERIALS, INCLUDING THE SECTION DESCRIBING

close of business on the record date, August 2, 2000, will be entitled to notice
of, and to vote at, the special meeting or any adjournment or postponement of
the meeting.

     You will be most welcome at the special meeting, and we hope that you can
attend. Our directors and officers will be present to answer your questions. In
addition, as required under Delaware law, we will make available at our
principal executive offices at least ten days before the date of the special

     Your vote is very important, regardless of the number of shares you own.

                                      By Order of the Board of Directors,

                                 (678) 375-3000

To Our Stockholders:

     You are cordially invited to attend a special meeting of stockholders of
CheckFree Corporation, to be held on [                    ], 2000, at [     ].,
local time, at our executive offices located at 4411 East Jones Bridge Road,
Norcross, Georgia.

     At the meeting, you will be asked to vote on a proposal to approve the
issuance of 10 million shares of CheckFree common stock, $0.01 par value, and
warrants to purchase up to an additional 10 million shares of CheckFree common
stock, to Bank of America, N.A., a national banking association, under a
strategic agreement with Bank of America through which CheckFree Services
Corporation, our wholly owned subsidiary, will acquire certain of Bank of
America's electronic billing and payment assets and we will provide electronic
billing and payment services to Bank of America's customers over the next ten
years.

     At the effective time of the share issuance, none of the warrants will be
vested and exercisable. The warrants will vest and become exercisable in stages
based on: (1) the number of Bank of America customers using our electronic
billing and payment services; and (2) the number of eBills that Bank of America
delivers per month. To earn all of the warrants, at least 10 million Bank of
America customers must be using our services, and Bank of America must be
delivering at least 10 million eBills per month.

     You are not being asked to approve the strategic agreement with Bank of
America or the asset purchase. Our board of directors has approved the strategic
agreement and the transactions contemplated by the strategic agreement. You are
being asked only to approve the issuance of an aggregate of 20 million shares of
our common stock in connection with the transactions contemplated in the
strategic agreement.

     Completion of the transactions contemplated by the strategic agreement is
subject to a number of conditions, including approval by our stockholders of the
proposed issuance of our common stock and warrants at the special meeting. Even
if you approve the issuance of our common stock and warrants to Bank of America,
however, we cannot assure you that the transactions will be completed. Approval
of the share issuance proposal requires the affirmative vote of holders of a
majority of the outstanding shares of our common stock.

     Our common stock is listed on the Nasdaq National Market under the symbol
"CKFR." On August 14, 2000, the closing price of our common stock on the Nasdaq
National Market was $46.00 per share.

     Your vote is very important, regardless of the number of shares you own.
Please vote as soon as possible to make sure that your shares are represented at
the special meeting. To vote your shares, you may complete and return the
enclosed proxy card, or you may vote by telephone or the Internet. If you are a
holder of record, you may also cast your vote in person at the special meeting.
If your shares are held in an account at a brokerage firm or bank, you must
instruct your broker or bank how to vote your shares.

     Our board of directors has carefully reviewed and considered the terms of
the strategic agreement and has determined that the strategic agreement and the
transactions contemplated thereby are in the best interests of CheckFree and our
stockholders. Accordingly, the board of directors has unanimously approved the
strategic agreement and recommends that you vote "FOR" the share issuance to
Bank of America at the special meeting. The enclosed proxy statement provides
you with a summary of the proposed transactions with Bank of America and
additional information. Please give this information your careful attention.

     This proxy statement is first being mailed to our stockholders on or about
[                    ].

                                      Very truly yours,

                                      Peter J. Kight

     QUESTIONS AND ANSWERS ABOUT THE STRATEGIC AGREEMENT AND SHARE ISSUANCE

Q. WHAT AM I BEING ASKED TO VOTE UPON?

 A. You are being asked to approve the issuance of:

   - 10 million shares of our common stock, $0.01 par value, and

   - warrants to purchase up to an additional 10 million shares of our common
     stock,

   to Bank of America, under a strategic agreement with Bank of America, dated
   as of April 26, 2000. Under the strategic agreement, CheckFree Services
   Corporation, our wholly owned subsidiary, will acquire certain of Bank of
   America's electronic billing and payment assets and we will provide
   electronic billing and payment services to Bank of America's customers over
   the next ten years.

   At the effective time of the share issuance, none of the warrants issued will
   be vested. The warrants will vest and become exercisable in stages based on:

   - the number of Bank of America customers using our electronic billing and
     payment services; and

   - the number of eBills that Bank of America delivers per month.

   To earn all of the warrants, at least 10 million Bank of America customers
   must be using our services, and Bank of America must be delivering at least
   10 million eBills per month.

Q. WHY ARE CHECKFREE AND BANK OF AMERICA ENTERING INTO THE STRATEGIC AGREEMENT?

 A. We have entered into the strategic agreement because we believe that by
    combining our expertise in providing electronic billing and payment services
    with access to customers of the nation's largest bank, we will be able to
    accelerate the growth and acceptance of electronic billing and payment
    services faster than either company could do on its own. The increased
    adoption of our electronic billing and payment services will create the
    potential for stronger operating and financial results.

Q. WHAT STOCKHOLDER APPROVALS ARE NEEDED?

 A. The affirmative vote of the holders of a majority of the shares of our
    common stock voting in person or by proxy at the special meeting is required
    to approve the issuance of the shares and warrants in connection with the
    strategic agreement, provided that a quorum, which means a majority of the
    shares of our common stock outstanding on the record date, votes in person
    or by proxy at the special meeting.

Q. WHAT DO I NEED TO DO NOW?

 A. After carefully reading and considering the information contained in this
    proxy statement, please respond by:

   - completing, signing and dating your proxy card or voting instructions and
     returning it in the enclosed postage paid envelope; or

   - if available, by submitting your proxy or voting instructions by telephone
     or through the Internet, as soon as possible so that your shares may be
     represented at the special meeting.

Q. WHAT IF I DO NOT VOTE?

 A. If you fail to respond, your shares will not count toward a quorum necessary
    to conduct the vote at the special meeting, and will not be counted as
    either a vote for or against the share issuance proposal.

    If you respond and do not indicate how you want to vote, your proxy will be
    counted as a vote in favor of the share issuance proposal.

Q. CAN I CHANGE MY VOTE AFTER I HAVE DELIVERED MY PROXY?

 A. Yes. You can change your vote at any time before your proxy is voted at the
    special meeting. You can do this in one of four ways.

   - First, you can revoke your proxy.

   - Second, you can submit a new proxy.

   If you choose either of these two methods, you must submit your notice of
   revocation or your new proxy to the Secretary of CheckFree before the special
   meeting. If your shares are held in an account at a brokerage firm or bank,
   you should contact your brokerage firm or bank to change your vote.

   - Third, if you are a holder of record, you can attend the special meeting
     and vote in person.

                                        3
<PAGE>   6

   - Fourth, if you submit your proxy or voting instructions electronically
     through the Internet or by telephone, you can change your vote by
     submitting a proxy at a later date, using the same procedures, in which
     case your later submitted proxy will be recorded and your earlier proxy
     revoked.

Q. WHEN DO YOU EXPECT THE SHARE ISSUANCE TO BE COMPLETED AND THE STRATEGIC
   AGREEMENT TO BECOME EFFECTIVE?

 A. We are working to complete the share issuance and the transactions
    contemplated by the strategic agreement as soon as possible after our
    special meeting. We expect to close the transactions in the Fall of 2000.

Q. WHO CAN HELP ANSWER MY QUESTIONS?

 A. If you have any questions about the strategic agreement or the share
    issuance proposal, or how to submit your proxy, or if you need additional
    copies of the proxy statement or the enclosed proxy card or voting
    instructions, you should contact:

THE STRATEGIC AGREEMENT AND SHARE ISSUANCE

     We and CheckFree Services Corporation have entered into an Amended and
Restated Strategic Master Alliance Agreement with Bank of America, dated as of
April 26, 2000, which governs the share issuance and the purchase of certain of
Bank of America's electronic billing and payment assets, as well as the ongoing
business relationship between us and Bank of America and its subsidiaries.

     Under the strategic agreement, at the closing:

     - we will issue 10 million shares of our common stock and warrants to
       purchase up to an additional 10 million shares of our common stock to
       Bank of America, and will make an additional cash payment to Bank of
       America of $35 million;

                                        5
<PAGE>   8

     - Bank of America will transfer certain of its electronic billing and
       payment assets and liabilities to CheckFree Services Corporation pursuant
       to a Purchase and Assumption Agreement; and

     - we will begin to provide electronic billing and payment services to Bank
       of America's customers pursuant to a Services Agreement between us and
       Bank of America.

     We have included a copy of the strategic agreement in this proxy statement
as Appendix A. We encourage you to read the strategic agreement because it is
the legal document that governs the share issuance and related transactions
described in this proxy statement. Additionally, we have either entered into, or
will at the closing of the strategic agreement enter into, the following
agreements:

     - A Services Agreement, which details the electronic billing and payment
       related services that we will supply to Bank of America, the level of
       service, and the fees we will receive. It has a basic term of ten years,
       although it may be extended, and on 12 months prior notice and payment of
       half of the remaining minimum fees and forfeiture of all warrants, it may
       be terminated by Bank of America any time after two years. The Services
       Agreement provides for minimum fees to us of $50 million per year.

     - A Registration Rights Agreement, which provides for the registration
       under applicable securities laws of the stock issued under the strategic
       agreement and related agreements.

     - A Warrant Agreement, which sets forth the terms under which Bank of
       America may acquire up to 10 million shares of our common stock.

     - A Stock Restriction Agreement, which imposes certain restrictions on Bank
       of America's ability to sell the stock and warrants issued under the
       strategic agreement and related agreements.

     - An EBP Transition Agreement, under the terms of which Bank of America
       will continue to perform certain functions in support of the legacy
       platforms and the gradual transition of these functions to us, and for
       our payment of fees to Bank of America to reimburse it for certain of the
       costs of providing these functions during the transition period.
     - A Purchase and Assumption Agreement, which provides for the transfer of
       certain tangible and intangible assets used by Bank of America in its
       operation of the legacy systems.

     CONDITIONS TO THE COMPLETION OF THE STRATEGIC AGREEMENT. Each of our and
Bank of America's obligations to consummate the strategic agreement is subject
to satisfaction or waiver of specified conditions, including those listed below:

     - approval of the share issuance proposal by our stockholders;

     - receipt of all required regulatory approvals and submission of all
       required filings with governmental entities;

     - the absence of legal prohibitions to the strategic agreement and the
       transactions contemplated by the strategic agreement; and

     - the other party's material compliance with its obligations under the
       strategic agreement prior to the closing, and the truth and accuracy of
       the representations made by such party.

     In addition, it is a condition to Bank of America's obligation to
consummate the closing that the transactions contemplated by the strategic
agreement not trigger the issuance or exercise of any rights of our stockholders
under our Stockholders' Rights Plan.

     TERMINATION OF THE STRATEGIC AGREEMENT. We and Bank of America may
terminate the strategic agreement at any time by mutual written consent. In
addition, either party may terminate the purchase agreement if:

     - our stockholders fail to approve the share issuance proposal by October
       1, 2000, or if the transaction is pending approval by a government
       agency, and stockholder approval is not obtained by the earlier of
       December 31, 2000, or 40 days following the receipt of such government
       approval; or

     - the Services Agreement is terminated.

STOCKHOLDER APPROVAL AND THE CHECKFREE SPECIAL MEETING

     APPROVAL OF CHECKFREE'S STOCKHOLDERS. The affirmative vote of holders of a
majority of the shares of our common stock voting in person or by proxy at the
special meeting, provided that a
                                        6
<PAGE>   9

quorum is present, is required to approve the share issuance proposal.

     THE SPECIAL MEETING AND THE RECORD DATE. Our stockholders will vote on the
share issuance proposal at a special meeting that will be held at our executive
offices located at 4411 East Jones Bridge Road, Norcross, Georgia, on
[                    ], 2000, starting at [  ].m., local time. Our stockholders
may vote at the special meeting if they owned shares of our common stock at the
close of business on August 2, 2000, which is the record date for the special
meeting. Each share will have one vote. On the record date, approximately
58,451,095 shares of our common stock were outstanding.

     PROCEDURES FOR VOTING YOUR SHARES. Your vote is very important, regardless
of the number of shares you own. Please vote as soon as possible to make sure
that your shares are represented at the special meeting. You may vote your
shares by signing your proxy card and mailing it in the enclosed return
envelope, or you may be able to submit your proxy or voting instructions by
telephone or by the Internet. If you are a holder of record, you may vote in
person at the special meeting. If you do not include instructions on how to vote
your properly executed proxy card, your shares will be voted FOR approval of the
share issuance proposal. If your shares are held in an account at a brokerage
firm or bank, your broker will vote your shares only if you provide instructions
on how to vote by following the information provided to you by your broker.

     PROCEDURE FOR CHANGING YOUR VOTE. You can change your vote at any time
before your proxy is voted at the special meeting. You can do this in one of
four ways.

     - First, you can send a written notice stating that you are revoking your
       proxy.

     - Second, you can complete and submit a new proxy card.

If you choose either of these two methods, you must submit your notice of
revocation or your new proxy for our common stock to our Corporate Secretary at
the address indicated at the beginning of this "Summary" section of the proxy
statement. If your shares are held in an account at a brokerage firm or bank,
you should contact your broker to change your vote.

     - Third, if you are a holder of record, you can attend the special meeting
       of stockholders and vote in person.

     - Fourth, to revoke a proxy previously submitted electronically through the
       Internet or by telephone, you may simply submit a proxy at a later date,
       using the same procedures, in which case your later submitted proxy will
       be recorded and your earlier proxy revoked.

     APPRAISAL RIGHTS. Under Delaware law, our stockholders are not entitled to
appraisal rights in connection with the share issuance proposal or the asset
purchase.

     SHARE OWNERSHIP BY OUR MANAGEMENT. On the record date, our directors and
executive officers were entitled to vote approximately 12.6% of our outstanding
common stock.

FEDERAL INCOME TAX CONSEQUENCES

     For United States federal income tax purposes, no income, gain or loss will
be recognized by CheckFree or our stockholders as a result of the strategic
agreement or the asset purchase. See "The Strategic Agreement and Share Issuance
-Material United States Federal Income Tax Consequences of the Strategic
Agreement." We urge you to consult your own tax advisor to determine the effect
of the strategic agreement under federal, state, local and foreign tax laws.

ACCOUNTING TREATMENT

     The strategic agreement will be recorded as an asset purchase for
accounting purposes.

the symbol "CKFR." On April 25, 2000, the last trading day before the public
announcement of the execution of the strategic agreement, our common stock

practicable date prior to the printing of this proxy statement, our common stock
closed at $[     ] per share.

REGULATORY MATTERS

     All material regulatory approvals required to permit the consummation of
the strategic agreement have already been obtained. The waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act expired on [                    ],

                                  RISK FACTORS

     In addition to the other information contained in or incorporated by
reference into this proxy statement, you should carefully consider the following
risk factors in deciding whether to vote for the share issuance proposal.

WE MAY FAIL TO REALIZE THE ANTICIPATED BENEFITS OF THE STRATEGIC AGREEMENT.

     The success of the strategic agreement will depend, in part, on our ability
to realize the anticipated growth opportunities and synergies from combining
Bank of America's electronic billing and payment assets with our business. To
realize the anticipated benefits of the strategic agreement, our management team
must develop strategies and implement a business plan that will:

     - effectively combine Bank of America's electronic billing and payment
       assets with our assets and services;

     - successfully use the anticipated opportunities for cross-promotion and
       sales of the products and services of CheckFree and Bank of America; and

     - while integrating Bank of America's electronic billing and payment assets
       with our operations, maintain adequate focus on our core businesses in
       order to take advantage of competitive opportunities and to respond to
       competitive challenges.

     If our management team is not able to develop strategies and implement a
business plan that achieves these objectives, we may not realize the anticipated
benefits of the strategic agreement. In particular, anticipated growth in
revenue, earnings before interest, taxes, depreciation, and amortization, or
"EBITDA," and cash flow may not be realized, which would have an adverse impact
on us and the market price of our common stock.

WE MAY NOT BE ABLE TO PROVIDE ELECTRONIC BILLING AND PAYMENT SERVICES TO THE
BANK OF AMERICA SUBSCRIBERS FOR THE FEES WE AGREED TO IN THE STRATEGIC
AGREEMENT.

     The success of the strategic agreement will depend, in part, on our ability
to ultimately provide electronic billing and payment services to the Bank of
America subscribers at a cost to us that is less than the fees we have agreed to
receive. If we are unable to provide electronic billing and payment services to
the Bank of America subscribers profitably, the strategic agreement will have a
material adverse effect on our business, financial condition and results of
operations.

BANK OF AMERICA'S MARKETING EFFORTS MAY NOT BE SUCCESSFUL IN GENERATING
ADDITIONAL SUBSCRIBERS FOR OUR ELECTRONIC BILLING AND PAYMENT SERVICES.

     If Bank of America's marketing efforts to generate additional subscribers
are not successful, it could have a material adverse effect on our business,
financial condition and results of operations. Although Bank of America
currently lists some 400,000 subscribers to their legacy electronic billing and
payment services, we do not know how many of those subscribers actively use
those services or how many of those subscribers will migrate to our electronic
billing and payment services. In order to realize the benefit of the strategic
agreement and to consistently increase and maintain our profitability, we must
encourage the existing Bank of America legacy subscribers to actively utilize
our billing and payment services, as well as generate additional subscribers
from the Bank of America base of customers. We currently serve an additional
approximately 400,000 Bank of America customers on our own systems under the
terms of a pre-existing contract.

OUR ASSUMPTION OF CERTAIN LONG-TERM LEASEHOLD OBLIGATIONS COULD HAVE AN ADVERSE
IMPACT ON OUR RESULTS OF OPERATIONS.

     As part of the strategic agreement, we are assuming certain of Bank of
America's long-term leasehold obligations which, if we are unable to use the
leased premises efficiently in our business (or find a third party

                                        8
<PAGE>   11

to assume the leasehold obligations), could have a material adverse effect on
our profitability and results of operations.

OUR ABILITY TO SUCCEED IN TRANSITIONING BANK OF AMERICA'S BILLING AND PAYMENT
SERVICES FROM ITS LEGACY SYSTEM TO OUR SYSTEM IS DEPENDENT ON RETAINING
QUALIFIED BANK OF AMERICA EMPLOYEES KNOWLEDGEABLE IN THE OPERATION OF BANK OF
AMERICA'S LEGACY SYSTEM.

     The success of the strategic agreement is dependent on our ability to
retain qualified Bank of America employees with experience operating Bank of
America's billing and payment processing system. Bank of America operates its
electronic billing and payment services on a legacy system that we expect to
migrate to our processing systems. If we are unable to retain the experienced
Bank of America employees through the transition and migration process, we will
have to either divert our current employees from other important work or incur a
significant expense to hire people qualified to operate the legacy system to
assist us with the transition and migration process. Competition for qualified
employees is intense and employees qualified to operate a legacy system are in
short supply.

WE ARE REQUIRED TO DEPRECIATE THE ACQUIRED ASSETS OVER THEIR USEFUL LIVES WHICH
WILL CAUSE OUR EARNINGS PER SHARE TO DECREASE.

     Because we will be accounting for the transaction as an asset purchase, the
purchase will result in a charge to our earnings that will decrease your
earnings per share. We will be required to amortize approximately $412 million
over a period of ten years or approximately $41.2 million per year.

     We will issue 10 million shares of our common stock in connection with the
asset purchase. Assuming the transaction was completed on July 1, 1998, the
strategic agreement would result in immediate and substantial dilution of per
share earnings from $0.18 diluted to $(0.48) diluted for the year ended June 30,
1999, and dilution of per share earnings from $(0.23) to $(0.38) for the nine
months ended March 31, 2000. The anticipated dilution could have a negative
impact on the market price of our common stock. Analysts and investors carefully
review a company's earnings per share and often base investment decisions on a
company's per share earnings.

AVAILABILITY OF SIGNIFICANT AMOUNTS OF OUR COMMON STOCK FOR SALE IN THE FUTURE
COULD ADVERSELY AFFECT OUR STOCK PRICE.

     If we complete the strategic agreement, we will issue to Bank of America an
aggregate of 10 million shares of our common stock and warrants to acquire an
additional 10 million shares of our common stock.

     We have agreed to provide Bank of America with registration rights in
connection with the strategic agreement. If Bank of America, by exercising its
registration rights, causes a large number of shares to be registered and sold
in the public market, these sales may have an adverse effect on the market price
of our common stock. Two years after the closing of the strategic agreement, or
one year after the warrants are exercised, Bank of America may be able to sell
up to the greater of one percent of our outstanding common stock or our average
weekly trading volume over a four week period in reliance on registration
exemptions. Sales of substantial amounts of our common stock by Bank of America,
or the perception that these sales could occur, may adversely affect prevailing
market prices for our common stock.

OUR COMMON STOCK HAS BEEN VOLATILE SINCE DECEMBER 15, 1999.

     Since December 15, 1999, our stock price has been extremely volatile,
trading at a high of $125.63 per share and a low of $28.50 per share for the
period. Our stock price could dramatically decrease between the time that our
stockholders vote on the share issuance proposal and the time the strategic
agreement closes. We cannot assure that the price of our common stock at the
time you vote on the share issuance proposal

                                        9
<PAGE>   12

will be the same as the price of our common stock when we consummate the
strategic agreement. The volatility in our stock price has been caused by:

     - actual or anticipated fluctuations in our operating results;

     - actual or anticipated fluctuations in our subscriber growth;

     - announcements by us, our competitors or our customers;

     - announcement of the execution of merger agreements with BlueGill
       Technologies, Inc. and TransPoint;

     - announcement of the signing of the strategic agreement with Bank of
       America;

     - announcements of the introduction of new or enhanced products and
       services by us or our competitors;

     - announcements of joint development efforts or corporate partnerships in
       the electronic commerce market;

     - market conditions in the banking, telecommunications, technology and
       other emerging growth sectors;

     - rumors relating to our competitors or us; and

     - general market or economic conditions.

PROXY STATEMENT

     We are furnishing this proxy statement to you in connection with the
solicitation of proxies by our board of directors in connection with the share
issuance proposal.

     We are first sending this proxy statement to our stockholders on or about
[               ], 2000.

DATE, TIME AND PLACE

     The special meeting is scheduled to be held as follows:

                            [               ], 2000
                            [          ], local time
                          4411 East Jones Bridge Road
                               Norcross, Georgia

PURPOSE OF THE SPECIAL MEETING

     The special meeting is being held so that our stockholders may consider and
vote upon:

     - a proposal to approve the issuance of 10 million shares of our common
       stock and warrants to purchase up to an additional 10 million shares of
       our common stock to Bank of America, under a strategic agreement with
       Bank of America through which CheckFree Services Corporation, our wholly
       owned subsidiary, will acquire certain of Bank of America's electronic
       billing and payment assets and we will provide electronic billing and
       payment services to Bank of America's customers over the next ten years;
       and

                                       12
<PAGE>   15

     - to transact any other business that properly comes before the special
       meeting or any adjournment or postponement of the special meeting.

     If our stockholders approve the share issuance proposal, upon the
completion of the strategic agreement, Bank of America will receive 10 million
shares of our common stock or approximately 14.6% of our outstanding common
stock. Bank of America will also receive warrants to purchase up to an
additional 10 million shares of our common stock, which will vest in stages as
Bank of America meets certain milestones. For all warrants to vest, at least 10
million Bank of America customers must be using CheckFree services, and Bank of
America must be delivering at least 10 million eBills per month. At closing,
none of the warrants will be vested or exercisable.

     If our stockholders do not approve the share issuance proposal, we or Bank
of America may terminate the strategic agreement. See "The Strategic Agreement
and Share Issuance -- Termination, Amendment and Waiver."

RECORD DATE

     Our board of directors has fixed the close of business on Wednesday, August
2, 2000, as the record date for determination of our stockholders entitled to
notice of, and to vote at, the special meeting. On the record date, there were
58,451,045 shares of our common stock outstanding, held by approximately 668
holders of record.

VOTE REQUIRED FOR ADOPTION OF THE SHARE ISSUANCE PROPOSAL

     A majority of our outstanding shares of common stock must be represented,
either in person or by proxy, to constitute a quorum at the special meeting. A
quorum is the minimum number of stockholders required to transact business or
take a vote. Under the terms of the strategic agreement, the affirmative vote of
the holders of a majority of our common stock voting in person or by proxy at
the special meeting is required to approve the share issuance proposal.

     As of the record date, our directors and executive officers and their
affiliates owned approximately 12.6% of the outstanding shares of our common
stock.

PROXIES

     All shares of our common stock represented by properly executed proxies or
voting instructions received before or at the special meeting will, unless the
proxies or voting instructions are revoked, be voted in accordance with the
instructions indicated on those proxies or voting instructions. If no
instructions are indicated on a properly executed proxy card or voting
instructions, the shares will be voted "FOR" approval of the share issuance
proposal. You are urged to mark the box on the proxy card to indicate how to
vote your shares.

     If a properly executed proxy card or voting instruction is returned and the
stockholder has abstained from voting on adoption of the share issuance
proposal, the CheckFree common stock represented by the proxy or voting
instructions will be considered present at the special meeting for purposes of
determining a quorum, but will not be considered to have been voted in favor of
approval of the share issuance proposal. If your shares are held in an account
at a brokerage firm or bank, you must instruct them on how to vote your shares.
If an executed proxy card is returned by a broker or bank holding shares which
indicates that the broker or bank does not have discretionary authority to vote
on approval of the share issuance proposal, the shares will be considered
present at the meeting for purposes of determining the presence of a quorum, but
will not be considered to have been voted in favor of approval of the share
issuance proposal. Your broker or bank will vote your shares only if you provide
instructions on how to vote by following the information provided to you by your
broker.

     We do not expect that any matter other than approval of the share issuance
proposal will be brought before the special meeting. If, however, other matters
are properly presented, the persons named as proxies

                                       13
<PAGE>   16

will vote in accordance with their judgment with respect to those matters,
unless authority to do so is withheld on the proxy card.

     A stockholder may revoke his or her proxy at any time before it is voted
by:

     - notifying in writing the Corporate Secretary of CheckFree at 4411 East
       Jones Bridge Road, Norcross, Georgia 30092;

     - granting a subsequently dated proxy; or

     - appearing in person and voting at the special meeting if you are a holder
       of record.

Attendance at the special meeting will not in and of itself constitute
revocation of a proxy.

VOTING ELECTRONICALLY OVER THE INTERNET OR BY TELEPHONE

     Instead of submitting your vote by mail on the enclosed proxy card or
voting instructions, you may have the option to submit your proxy or voting
instructions electronically through the Internet or by telephone. Please note
that there are separate arrangements for using the Internet and telephone
depending on whether your shares are registered in our stock records in your
name or in the name of a brokerage firm or bank. You should check your proxy
card or voting instructions forwarded by a broker, bank or other holder of
record to see which options are available.

     The Internet and telephone procedures for submitting your proxy or voting
instructions are designed to authenticate stockholders identities, to allow
stockholders to have their shares voted and to confirm that their instructions
have been properly recorded. A prior proxy submitted by the Internet or
telephone may be revoked by the submission of a letter proxy using any allowable
method of proxy submission indicated in this proxy statement, including by a
subsequent Internet or telephonic proxy.

SOLICITATION OF PROXIES

     We will bear the expenses incurred in connection with the printing and
mailing of this proxy statement. We and our proxy solicitors will also request
banks, brokers and other intermediaries holding shares of our common stock
beneficially owned by others to send this proxy statement to, and obtain proxies
from, the beneficial owners and will reimburse the holders for their reasonable
expenses in so doing.

                   THE STRATEGIC AGREEMENT AND SHARE ISSUANCE

OVERVIEW

     We and CheckFree Services Corporation have entered into an Amended and
Restated Strategic Master Alliance Agreement with Bank of America, dated as of
April 26, 2000, which governs the asset purchase and share issuance, as well as
the ongoing business relationship between us and Bank of America. Under the
strategic agreement, at the closing:

     - we will issue 10 million shares of our common stock and warrants to
       purchase up to an additional 10 million shares of our common stock to
       Bank of America;

     - Bank of America will transfer certain of its electronic billing and
       payment assets and liabilities to CheckFree Services Corporation pursuant
       to a Purchase and Assumption Agreement; and

     - we will begin to provide electronic billing and payment services to Bank
       of America's customers pursuant to a Services Agreement between us and
       Bank of America.

The strategic agreement consists of several related agreements between us and
Bank of America, which we have entered into either directly or through our
subsidiaries. These related agreements are described below.

RECOMMENDATION OF OUR BOARD OF DIRECTORS; OUR REASONS FOR THE STRATEGIC
AGREEMENT

     Our board of directors has carefully reviewed and considered the terms of
the strategic agreement and has determined that the strategic agreement and the
transactions contemplated thereby are in the best interests of CheckFree and our
stockholders, are fair to you as a CheckFree stockholder and are in your best
interest. Accordingly, the board of directors has unanimously approved the
strategic agreement and recommends that you vote "FOR" the share issuance to
Bank of America at the special meeting. In reaching its decision to recommend
the approval of the share issuance proposal to you, our board of directors
consulted with our legal advisors and with our senior management and considered
the following material factors:

     - the potential to accelerate the adoption of electronic billing and
       payment services through marketing efforts by the nation's largest bank
       to its customers;

     - the expectation that we will have greater technology, sales, marketing,
       distribution and customer service and resources leading to the
       possibility of stronger operating and financial results for CheckFree;

     - the strategic fit, including the belief that the strategic agreement has
       the potential to enhance stockholder value through increased growth
       opportunities and the cost savings achievable and synergies resulting
       from the strategic agreement and the asset purchase;

     - the opportunities, as a result of entering into the strategic agreement,
       of a stronger strategic relationship with Bank of America;

     - the benefit of obtaining a stream of minimum revenue guarantees equaling
       $50 million during the next ten years from Bank of America;

     - the potential benefits to:

        (1) our customers, who should benefit from our end-to-end solution for
            sending, receiving and paying bills being utilized by more users as
            a result of the strategic agreement, and

        (2) our strategic partners, who will be able to use our services and
            technology to reach a greater combined group of consumers;

     - the information and presentations by our management concerning the
       results of their business due diligence and the potential growth
       opportunities and synergies resulting from the strategic agreement; and

     - the terms of the strategic agreement and the related agreements,
       including the amount of the consideration to be received by Bank of
       America.

     Our board of directors also considered the potential adverse effects and
risks associated with the strategic agreement, including those risks set forth
in the section titled "Risk Factors" in this proxy statement and concluded that
the potential benefits of the strategic agreement outweighed the potential
adverse effects and risks. The list of potential adverse effects and risks
considered by our board included, but was not limited to, the following:

     - the challenges of combining Bank of America's assets with our assets and
       the risk of not being able to convert Bank of America's electronic
       billing and payment customers from Bank of America's processing system to
       our processing system;

     - the risk of not achieving operational efficiencies or accelerating growth
       of our electronic billing and payment services;

     - the risk of diverting management focus and resources from other strategic
       opportunities and from operational matters while working to implement the
       strategic agreement;

     - the risk that the strategic agreement and the transactions contemplated
       by that agreement will not be consummated;

                                       15
<PAGE>   18

     - the obligation of registering the shares of our common stock under
       specified circumstances; and

     - the assets that will be recorded initially on our balance sheet and
       amortized on a straight-line basis as a charge against earnings over a
       ten year period.

     This discussion of the information and factors considered by our board of
directors is not intended to be exhaustive, but includes the material factors
considered. In view of the variety of material factors considered in connection
with the evaluation of the strategic agreement and share issuance, our board of
directors did not find it practicable to quantify or otherwise assign relative
weights or rank to the factors it considered in approving strategic agreement.
In considering the factors described above, individual members of the board may
have given different weight to various factors. Instead, our board of directors
considered all these factors as a whole and overall considered them to be
favorable and to support its recommendation.

COMPLETION AND EFFECTIVENESS OF THE STRATEGIC AGREEMENT

     The transactions contemplated by the strategic agreement will be completed
when all of the conditions to completion of the strategic agreement are
satisfied or waived, including the approval of the share issuance proposal by
our stockholders. For a summary of the conditions of each of the parties to
close the strategic agreement, see "The Strategic Agreement and Share Issuance
-Conditions Precedent to Closing." We are working toward completing the
transactions contemplated by the strategic agreement as quickly as possible, and
expect to do so shortly after the special meeting of our stockholders, provided
that we have obtained the necessary regulatory approvals. We expect that the
strategic agreement will be closed during the Fall of 2000.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE STRATEGIC
AGREEMENT

     For United States federal income tax purposes, no income, gain or loss will
be recognized by CheckFree or our stockholders as a result of the strategic
agreement or the asset purchase. We urge you to consult your own tax advisor to
determine the effect of the strategic agreement under federal, state, local and
foreign tax laws.

ACCOUNTING TREATMENT OF THE STRATEGIC AGREEMENT

     The strategic agreement will be recorded as an asset purchase for
accounting purposes.

REGULATORY MATTERS

     We have summarized below the material regulatory requirements affecting the
strategic agreement. All material regulatory approvals required to permit
consummation of the strategic agreement have already been obtained from the
applicable regulation authorities or the necessary waiting periods have expired.
The strategic agreement and related issuance of shares are subject to the
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, which
prevents specified transactions from being completed until required information
and materials are furnished to the Antitrust Division of the Department of
Justice and the Federal Trade Commission and specified waiting periods are
terminated or expire. On July 31, 2000, we filed the required information and
materials with the Department of Justice and the Federal Trade Commission. On
[               ], 2000, the waiting period under the Hart-Scott-Rodino Act
terminated.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may, however, challenge the strategic agreement on antitrust grounds
after termination of the waiting period. Accordingly, at any time before or
after the closing of the strategic agreement, either the Antitrust Division of
the Department of Justice or the Federal Trade Commission could take action
under the antitrust laws as it deems necessary or desirable in the public
interest, or other persons, including states, could take action under the
antitrust laws, including seeking to enjoin the transactions contemplated by the
strategic agreement. Additionally, at any time before or after the closing of
the strategic agreement, notwithstanding the fact that the applicable waiting
period was terminated, any state could take action under the antitrust laws as
it deems necessary or desirable in the public interest.

                                       16
<PAGE>   19

     Additionally, the parties will seek any and all other regulatory approvals
that may be required or imposed prior to the closing of the strategic agreement.

NASDAQ NATIONAL MARKET LISTING OF CHECKFREE COMMON STOCK TO BE ISSUED PURSUANT
TO THE STRATEGIC AGREEMENT

     We will use our reasonable best efforts to cause the shares of our common
stock that are to be issued pursuant to the strategic agreement to be approved
for listing on the Nasdaq National Market, subject to official notice of
issuance, before the closing of the strategic agreement.

APPRAISAL RIGHTS

     Under Delaware law, our stockholders are not entitled to appraisal rights
in connection with the share issuance proposal or any other transactions
contemplated by the strategic agreement.

RESTRICTIONS ON SALES OF SHARES BY BANK OF AMERICA

     Bank of America will be limited in its ability to sell, transfer or assign
our common stock and warrants to purchase our common stock that it will receive
at closing. Under a Stock Restriction Agreement, dated as of April 26, 2000,
between us and Bank of America, Bank of America may not sell, assign or
otherwise transfer shares of our common stock except:

     - in accordance with Rule 144 under the Securities Act of 1933, after
       holding the shares of common stock for two years from the date of the
       Stock Restriction Agreement, or, for shares acquired upon the exercise of
       warrants, after one year from the date that the warrants were exercised;

     - to a qualified institutional buyer, as defined in the Stock Restriction
       Agreement;

     - pursuant to an effective registration statement under the Securities Act
       of 1933, covering the resale of the shares, which we have registered on
       Bank of America's behalf under a Registration Rights Agreement between
       the parties; or

     - with our prior written consent.

We will also have a right of first refusal on any shares that Bank of America
proposes to sell or transfer, except for shares registered pursuant to the
Registration Rights Agreement. In addition, as long as the Stock Restriction
Agreement is in effect, Bank of America may not:

     - purchase shares of our common stock without the prior written consent of
       our board of directors or other authorized representative;

     - solicit proxies in opposition to any recommendation of our management;

     - grant a proxy to anyone other than our designated nominee; or

     - initiate or participate in any group that proposes, without the support
       of our board of directors, any change in control of CheckFree.

the strategic agreement are subject to the satisfaction or waiver of each of the
following conditions:

     - approval of the share issuance proposal by our stockholders;

by an authorized officer of the party against whom the waiver is to be charged.

                       DESCRIPTION OF RELATED AGREEMENTS

     In addition to strategic agreement, we, either directly or through
CheckFree Services Corporation, have entered into the following related
agreements with Bank of America or Banc of America E-Commerce.

PURCHASE AND ASSUMPTION AGREEMENT

     We and CheckFree Services Corporation have entered into a Purchase and
Assumption Agreement with Bank of America and its wholly owned subsidiary Bank
of America Technology and Operations, Inc., dated as of August 8, 2000, under
which CheckFree Services Corporation will purchase certain of Bank of America's
electronic billing and payment assets, property and rights. These assets,
property and rights comprise Bank of America's bill payment and presentment
platform, and include software, equipment, machinery, supplier lists, and
proprietary rights. We will also assume certain liabilities and commitments of
Bank of America relating to the electronic billing and payment assets.

     Under the purchase agreement, Bank of America will retain a perpetual,
royalty free, non-transferable, non-exclusive license to use the software that
CheckFree Services Corporation is acquiring in the asset purchase. In addition,
Bank of America will retain a similar license to use the software, processes and
ideas covered by a pending patent application with the U.S. Patent and Trademark
Office, which application is also being acquired in the asset purchase.

     The closing of the asset purchase is subject to satisfaction or waiver of
conditions similar to those provided in the strategic agreement, including the
approval of our stockholders of the share issuance proposal and the receipt of
all necessary regulatory approvals. In addition, each party's obligations to
complete the closing of the asset purchase are subject to the other party's
compliance with its covenants and obligations

                                       19
<PAGE>   22

under the purchase agreement. One such covenant requires that, from the date of
the purchase agreement until the effective time of the asset purchase, Bank of
America not:

     - sell, license, contract or otherwise encumber any of the purchased assets
       other than in the ordinary course of business in a manner that does not
       materially devalue the purchased assets; or

     - amend, modify or terminate any contract or agreement to which it is a
       party relating to the purchased assets without the prior written consent
       of CheckFree Services Corporation.

In addition, Bank of America agreed that from the date of the purchase agreement
until the time such agreement closes, it and its officers and employees would
use their best efforts to preserve the purchased assets in good order.

     We have included a copy of the Purchase and Assumption Agreement as
Appendix B to this proxy statement.

EBP TRANSITION AGREEMENT

     CheckFree Services Corporation, Bank of America and Bank of America
Technology and Operations have entered into a EBP Transition Agreement, dated as
of August 8, 2000, which governs Bank of America's gradual migration from its
current legacy operating system to the Genesis system. The transition agreement
addresses the terms and schedule of the migration, as well as each party's
obligations during the transition period. The agreement requires that Bank of
America continue to perform certain functions in support of the legacy platforms
and that we pay fees to Bank of America to reimburse it for certain of the costs
of providing these functions during the transition period.

     The agreement will be effective from the closing date of the Purchase and
Assumption Agreement until the earlier of such time as:

     - the parties terminate the strategic agreement;

     - 18 months following the closing date of the Purchase and Assumption
       Agreement; or

     - until the completion of all of the triggering events set forth in the
       schedules to the EBP Transition Agreement.

If, however, all of the triggering events referenced above are not completed
within 18 months of the closing date, the term of the agreement may be extended
at Bank of America's sole discretion.

SERVICES AGREEMENT

     We and Bank of America have entered into a Services Agreement, effective as
of the closing date of the strategic agreement, which details the electronic
billing and payment related services that we will supply to Bank of America, as
well as the level of service and the fees we will receive. The agreement has a
basic term of ten years, although it may be extended, and on 12 months prior
notice and payment of half of the remaining minimum fees and forfeiture of all
warrants, it may be terminated by Bank of America any time after two years. The
Services Agreement provides for minimum fees to us of $50 million per year.

     In connection with our provision of services under the Services Agreement,
we will create an instance of our Genesis operating system for Bank of America.
Bank of America and its customers will then be migrated from the various systems
currently used for its electronic billing and payment services to the new
operating system over time, currently estimated to be less than 18 months.
During this migration period, the terms of the EBP Transition Agreement provide
that Bank of America will continue to operate certain of the legacy systems
until they are transitioned to us. We will pay Bank of America to reimburse it
for the costs of providing these operating services.

                                       20
<PAGE>   23

WARRANT AGREEMENT

     We and CheckFree Services Corporation have entered into a Warrant
Agreement, dated as of April 26, 2000, with Bank of America, concerning the
issuance and terms of the warrants that we will issue to Bank of America at the
effective time. Each warrant represents the right to purchase one share of our
common stock at a price of $32.50 per share, subject to adjustment in the event
of a dividend, stock split, combination, reclassification, or other issuance.

     At the closing none of the warrants issued will be vested. The warrants
will vest and become exercisable in stages based on:

     - the number of Bank of America customers using our electronic billing and
       payment services; and

     - the number of eBills that Bank of America delivers per month.

     Bank of America may only transfer the warrants to an affiliate in
compliance with applicable securities laws, and provided that the transferee:

     - first agrees to sell or transfer the warrants only under the terms of the
       warrant agreement; and

     - enters into an agreement with us equivalent to the Stock Restriction
       Agreement.

     Once vested, Bank of America may exercise the warrants by providing us with
the warrant certificate, the warrant subscription, and payment for the number of
shares for which such warrant is being exercised. We will then issue and deliver
to Bank of America a certificate representing the shares, which may bear the
restrictive legends required by federal and applicable state securities laws.

     The warrants are also subject to the restrictions on transferability set
forth in the Stock Restriction Agreement between us and Bank of America. See
"The Strategic Agreement and Share Issuance -- Restrictions on Sales of Shares
by Bank of America."

REGISTRATION RIGHTS AGREEMENT

     In connection with the share issuance, we have agreed to grant Bank of
America certain registration rights with respect to the 10 million shares of
common stock and warrants to purchase up to an additional 10 million shares of
common stock that Bank of America will receive at closing. Under a Registration
Rights Agreement, dated as of April 26, 2000, between the parties:

     - Bank of America will have the right to have its shares and warrants
       included in any registration statement that we file under the Securities
       Act of 1933 (other than a Form S-4 or a Form S-8 registration statement)
       for an offering of our equity securities for our own account or for the
       account of any of our equity security holders; and

     - Bank of America may request that we file a registration statement on Form
       S-3 for the sale of the shares and warrants in an offering reasonably
       anticipated to exceed $2 million, provided that we will not be required
       to make such a registration if we have already effected two registrations
       in any twelve month period.

     The number of shares or warrants that Bank of America may include in any
registration statement may be reduced in the event that the managing underwriter
of such offering determines that:

     - the size of the offering that the parties intend to make, or

     - the combination of securities that the parties intend to include,

are such that the success of the offering would be materially and adversely
affected. In addition, Bank of America's registration rights will be subordinate
to the registration rights we have previously granted to Intuit Inc.

be received by our corporate Secretary at our principal executive offices, 4411

                              AMENDED AND RESTATED

                      STRATEGIC ALLIANCE MASTER AGREEMENT

     This Amended and Restated Strategic Alliance Master Agreement ("Agreement"
or "Master Agreement") is made by, between and among CHECKFREE HOLDINGS
CORPORATION ("CKFR") and its wholly-owned subsidiary CHECKFREE SERVICES
CORPORATION ("CSC") both Delaware corporations with their principal office at
4411 East Jones Bridge Road, Norcross, Georgia 30092, and BANK OF AMERICA, N.A.
("Bank"), a national banking association, with its principal office at 101 South
Tryon Street, Charlotte, North Carolina 28255. CKFR and CSC are occasionally
referred to herein as "CheckFree." Each are occasionally referred to as a
"Party" and collectively the "Parties." This Master Agreement amends and
restates the Strategic Alliance Master Agreement among the Parties dated April
26, 2000, and is and shall be effective as of such date.

                                   BACKGROUND

     CheckFree is one of the preeminent providers of electronic billing and
payment ("EBP") services in the United States. While Bank also provides billing
and payment services to its customers, the Parties believe that through the
relationship provided for in this Master Agreement and the other agreements and
schedules referred to herein (collectively, the "Alliance Agreements"), the
Parties can (i) accelerate user adoption of EBP; (ii) generate substantial
economies of scale in the provision of such services; and (iii) take advantage
of the relative strengths of the Parties.

     The relationship provided for in the Alliance Agreements encompasses (i)
outsourcing the EBP activities currently conducted by Bank to CheckFree,
including related commitments from Bank; (ii) the acquisition by CheckFree of
the assets, and the assumption of certain liabilities, associated with the EBP
activities conducted by Bank of America; (iii) a transition plan to govern the
interim period preceding CheckFree's creation for Bank of a separate and
segregated instance of its Genesis operating system, and the migration of Bank
and its customers from the various systems currently used for its EBP functions
to this targeted operating system; (iv) and the grant to Bank of shares of the
$0.01 par value common stock of CKFR (the "CKFR Common Stock") and warrants to
acquire additional shares of CKFR Common Stock, and other consideration
furnished by CheckFree; (v) the commitment by Bank to market EBP services to its
customers, and; (vi) various other matters as provided in the Alliance
Agreements.

     Consummation of all of the transactions required by this Master Agreement
and the other Alliance Agreements will require the clearance of the Federal
Trade Commission under the Hart-Scott-Rodino Anti-Trust Improvements Act (the
"HSR Act") and the approval of the shareholders of CheckFree. Accordingly, while
certain of the Alliance Agreements and schedules will be executed
contemporaneously herewith, with respect to certain other matters, certain
schedules are to be prepared and added later, and with respect to certain
agreements there are agreed-upon principles to be incorporated into agreements
that will be prepared and executed at a later date. The Parties agree, however,
to work in good faith to complete all such matters, with the objective of having
unfinished items completed by the date of the filing of the Proxy Statement for
the CheckFree Shareholders' Meeting.

     NOW THEREFORE, in consideration of the premises and the mutual agreements
and covenants herein, Bank and CheckFree hereby agree as follows:

                                   ARTICLE 1

                 THE SERVICES AGREEMENT AND RELATED AGREEMENTS

     1.1. Services Agreement. The Parties shall, contemporaneously with the
execution of this Agreement, and with an effective date as of the Closing (as
such term is defined in Section 8.1), enter into the Services
<PAGE>   27

Agreement in the form attached hereto as Exhibit A, which shall govern the
ongoing business relationship under which CheckFree shall provide EBP services
to Bank.

     1.2. Warrant Agreement. CKFR and Bank shall, contemporaneously with the
execution of this Agreement, and with an effective date as of the Closing, enter
into the Warrant Agreement, in the form attached hereto as Exhibit B,
establishing the conditions under which Bank will acquire vested rights in
warrants to purchase shares of CKFR Common Stock (any such warrants obtained by
Bank are referred to as the "Warrants" and any shares obtained upon exercise of
the Warrants are referred to as the "Warrant Shares"), and setting forth the
terms and conditions applying to the Warrants..

     1.3 Creation and Use of Special Marketing Fund.

     (a) Year One. At the Closing, Bank shall establish a special marketing fund
for the use and benefit of Bank for the express purpose of enhancing the
adoption and usage of EBP services by retail customers of Bank (the "Marketing
Fund"). Although the Parties will consult with respect to the usage of the
Marketing Fund, the timing, usage and allocation of the funds in the Marketing
Fund shall be under the control and direction of Bank provided Bank acts
consistently with the terms hereof. Bank shall expend not less than $25 million
of the Marketing Fund over a twelve-month period commencing with the launch of
EBP services on the Genesis platform for Bank as contemplated by the Services
Agreement (the "Marketing Date").

     (b) Year Two. On or before the first anniversary of the Marketing Date,
Bank shall contribute $20 million to the Marketing Fund for the express purpose
of enhancing the adoption and usage of EBP services by retail customers of Bank
provided Bank acts consistently with the terms hereof. The Parties shall
continue to consult regarding the usage of the funds, but timing, usage and
allocation shall remain under the control and direction of the Bank. The funds
contributed by Bank shall be expended over the twelve-month period commencing on
the first anniversary of the Marketing Date.

                                   ARTICLE 2

      CONSIDERATION, THE GRANT OF CKFR COMMON STOCK AND RELATED AGREEMENTS

     2.1. Stock Grant. CKFR shall, at the Closing, issue to Bank, or to a
wholly-owned subsidiary of the Bank if so directed by the Bank, for no
additional consideration, ten million shares of CKFR Common Stock.

     2.2 Stock Restriction Agreement. CKFR and Bank shall, contemporaneously
with the execution of this Master Agreement, and with an effective date as of
the Closing, enter into and execute a Stock Restriction Agreement in the form
attached hereto as Exhibit C. The Stock Restriction Agreement imposes certain
restrictions on Bank's ability to sell, transfer or assign the shares of CKFR
Common Stock received pursuant to Section 2.1 above. The Stock Restriction
Agreement also imposes restrictions on Bank of America's ability to sell,
transfer or assign the Warrant Shares.

     2.3 Registration Rights Agreement. CKFR and Bank shall, contemporaneously
with the execution of this Master Agreement, and with an effective date as of
the Closing, enter into and execute a Registration Rights Agreement in the form
attached hereto as Exhibit D, providing the terms and conditions under which the
Shares of CKFR Common stock acquired by Bank pursuant to Section 2.1 and the
Warrant Shares may be registered under the securities laws of the United States.

     2.4 Voting Agreement. CKFR and Bank shall, contemporaneously with the
execution of this Master Agreement, enter into and execute a Voting Agreement
substantially in the form attached hereto as Exhibit E (which Voting Agreement
also contemplates the execution by Microsoft Corporation and First Data
Corporation), which imposes certain restrictions on the transfer of the shares
of CKFR Common Stock acquired and to be acquired by Bank pursuant to this Master
Agreement and the Alliance Agreements, and requires that such shares be voted in
accordance with specific provisions of the Voting Agreement. CKFR shall use
commercially efforts to obtain the appropriate execution of the voting agreement
by Microsoft Corporation and First Data Corporation, and to obtain from
Microsoft Corporation and First Data Corporation an Approval of Conduct
Agreement substantially in the form of Exhibit F hereto.

                                       A-2
<PAGE>   28

     2.5 Cash Payment. CKFR shall, at closing, pay to Bank the sum of $35
million. Such funds shall be wired or otherwise transferred to an account at
Bank as Bank shall direct.

                                   ARTICLE 3

               AGREEMENTS REGARDING TRANSITION OF EBP OPERATIONS

     3.1 EBP Preliminary Services Agreement. CSC and Bank of America shall,
contemporaneously with the execution of this Agreement, execute a EBP
Preliminary Services Agreement substantially in the form attached hereto as
Exhibit G, setting forth the preliminary activities of CSC in working with Bank
during the period commencing on the Closing provided in Section 8.1 and ending
at the Closing Time of the Purchase and Assumption Agreement described in
Section 3.3 ("P&A Agreement").

     3.2 EBP Transition Agreement. The Parties contemplate that they will,
contemporaneously with the execution of the P&A Agreement, execute an EBP
Transition Agreement following the principles recited in Exhibit H, setting
forth the agreed upon plan whereby CSC and Bank will work together to migrate
certain Bank EBP customers from the systems currently used and operated by Bank
("Legacy Systems") to the target CSC Genesis system, and to provide for
operation of the Legacy Systems during the transition.

     3.3 Purchase and Assumption Agreement. The parties agree to negotiate in
good faith and with diligence to, as soon as practical following the execution
of this Agreement, execute a Purchase and Assumption Agreement following the
principles recited (and, where appropriate, incorporating the provisions set
forth) in Exhibit I providing for the acquisition and assumption by CSC of
certain assets, liabilities and relationships of Bank relating to the Legacy
Systems. The Parties acknowledge that there will be substantial due diligence
conducted during the period from the date hereof through the date of execution
and of the closing of the P&A Agreement and the transactions contemplated
thereby, and the Parties agree to conduct such due diligence in a manner
designed not to interrupt the business operations of the other. All such due
diligence shall be governed by the obligation of confidentiality set forth in
this Master Agreement. It is the intent of the Parties to finalize and execute a
definitive P&A Agreement on or before the date the Proxy is mailed to the
shareholders of CKFR as contemplated in Section 4.1 hereof, or as soon
thereafter as reasonably practicable.

                                   ARTICLE 4

       SHAREHOLDERS MEETING, REGULATORY REQUIREMENTS AND RELATED MATTERS

     4.1 Shareholders Meeting. As soon as reasonably practicable, CKFR shall
call a shareholders' meeting (the "Shareholders' Meeting"), to be held as soon
as reasonably practicable following receipt of all necessary clearances by the
SEC with respect to the proxy statement, for the purpose of voting upon approval
of the issuance of the shares of CKFR Common Stock and Warrants to Bank and such
other related matters as CKFR shall deem appropriate. In connection with the
Shareholders' Meeting, (i) CKFR shall prepare and file a preliminary proxy
statement (the "Proxy Statement") with the SEC and mail the final Proxy
Statement to its shareholders, (ii) Bank of America shall furnish to CKFR all
information concerning it that CKFR may reasonably request in connection with
such Proxy Statement, (iii) the Board of Directors of CKFR shall recommend
(subject to compliance with its fiduciary duties, following consultation with
its legal advisers) to its shareholders the approval of this Master Agreement
and other matters in connection therewith, and (iv) the Board of Directors and
officers of CKFR shall use their reasonable efforts to obtain such shareholders'
approval (subject to compliance with their fiduciary duties, following
consultation with CKFR's legal advisers).

     4.2 The Proxy Statement. To the best knowledge of CheckFree, neither the
Proxy Statement nor any other materials (or amendments thereof or supplements
thereto) to be furnished by CKFR to its shareholders in connection with the
transactions contemplated by this Agreement will, at the times such documents
are distributed to CKFR shareholders through the Effective Date, contain, with
respect to CKFR or any of its subsidiaries, any untrue statement of a material
fact or omit to state any information required to be stated

                                       A-3
<PAGE>   29

therein or omit to state any material fact necessary in order to make the
statements made therein, in light of the circumstances under which they are made
with respect to CKFR and its shareholders, not misleading.

     4.3 HSR Filing. To the extent required by applicable laws, rules or
regulations, as soon as practicable following the date hereof, Bank and
CheckFree shall make all pre-merger notification filings as may be required by
the HSR Act and implementing regulations; shall each provide the requisite
information in connection therewith, and shall copy each other on all filings
made thereunder, and all relevant correspondence to and from the respective
agencies with jurisdiction and authority under such Act. Further, Bank shall
undertake and make all filings or applications that may be required in order to
consummate the transactions contemplated by this Master Agreement. In the event
for any reason Bank is not able to acquire or hold the shares of CKFR Common
Stock or acquire or exercise the Warrants due to the lack of the requisite
clearances under the HSR Act and implementing regulations, or the restrictions
imposed on Bank or its holding company by the Office of the Comptroller of the
Currency or the Board of Governors of the Federal Reserve System, the Parties
shall take such steps as may be reasonably requested by Bank to allow it to
realize the economic value associated with the Warrants and the shares of CKFR
Common Stock, including, without limitation, facilitating a transfer of all or a
portion of the Warrants and shares of CKFR Common Stock to a Person able to
acquire the same, but all such transfers shall be nonetheless subject to the
provisions of the Stock Restriction Agreement; provided, however, that inasmuch
as the Parties recognize that ownership of the Shares, Warrants and Warrant
Shares by Bank is expected by CheckFree to provide an incentive to Bank to
foster and accelerate user and biller adoption of EBP, any steps requested by
Bank for the transfer of Shares, Warrants or Warrant Shares pursuant to this
Section 4.3 which are reasonably likely to diminish the financial incentive to
Bank shall be deemed unreasonable and therefore not required to be granted.

     4.4 Agreement as to Efforts to Consummate. Subject to the terms and
conditions of this Master Agreement and the other Alliance Agreements, each
Party agrees to use commercially reasonable efforts to take, or cause to be
taken, all actions, and to do, or cause to be done, all things necessary,
proper, or advisable under applicable laws to obtain all necessary consents and
approvals reasonably required in order to, and to consummate and make effective
as soon as reasonably practicable after the date of this Master Agreement, the
transactions contemplated by this Master Agreement and the other agreements
contemplated hereby, including using commercially reasonable efforts to lift or
rescind any order adversely affecting its ability to consummate the transactions
contemplated herein and therein. Bank shall maintain its EBP operations in the
ordinary course of business, consistent with past practices and shall use
commercially reasonable efforts to maintain key employees associated therewith.

                                   ARTICLE 5

              CERTAIN REPRESENTATIONS AND WARRANTIES OF CHECKFREE

     CheckFree hereby represents and warrants to Bank as follows:

Delaware, and has the power and authority to carry on its business as now

     5.2 Authority of CheckFree; No Breach By Agreement.

     (a) Subject to receipt of the approval of the shareholders of CKFR,

and perform its obligations under this Master Agreement and the Alliance
Agreements and to consummate the transactions contemplated hereby and thereby,
and such Agreements are, or shall be when executed and delivered, legal, valid,
and binding obligations of CheckFree, enforceable against CheckFree in
accordance with its terms (except in all cases as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, receivership,
conservatorship, moratorium, or similar laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceeding may be brought).

                                       A-4
<PAGE>   30

     (b) Neither the execution and delivery of this Master Agreement by
CheckFree, nor the consummation by CheckFree of the transactions contemplated
hereby or by the other Alliance Agreements, nor compliance by CheckFree with any
of the provisions hereof or thereof, will (i) conflict with or result in a
breach of any provision of CheckFree's Certificate of Incorporation or Bylaws or
any resolution adopted by the board of directors or the stockholders of
CheckFree, or (ii) result in a breach of any material contract to which
CheckFree is a party or, (iii) otherwise have a material adverse effect on
CheckFree, its business, operations or future prospects.

     (c) Other than in connection or compliance with the provisions of the
securities laws, and other than compliance with the HSR Act, no notice to,
filing with, or consent of, any public body or authority is necessary for the
consummation by CheckFree of the transactions contemplated in this Master
Agreement or any of the Alliance Agreements.

5.3 Capital Stock.

     (a) The authorized capital stock of CKFR consists of (i) 150,000,000 shares
of CKFR Common Stock, of which 52,486,670 shares were issued and outstanding as

the quarterly period ending December 31, 1999, and (ii) 15,000,000 shares of
preferred stock, par value $0.01 per share, none of which are issued and

issued in violation of any preemptive rights of the current or past stockholders
of CKFR. CKFR has agreed to issue 17,000,000 shares of CKFR Common stock in
connection with an announced transaction with First Data Corporation and
Microsoft Corporation, and has agreed to issue additional shares of CKFR Common
stock in connection with an announced transaction with Bluegill Technologies,
Inc., the number of which is dependent on a procedure set forth in the Agreement
and Plan of Merger dated as of December 20, 1999.

     (b) Except as set forth above or as previously disclosed in CKFR's SEC
Reports (as defined below) or otherwise set forth on Schedule 5.3, there are no
shares of capital stock or other equity securities of CheckFree outstanding and
no outstanding warrants, options or other similar rights relating to the capital
stock of CKFR.

     (c) The shares of CKFR Common Stock to be issued pursuant to Section 2.1
hereof, and the Warrant Shares, if, when, and as issued, shall be fully paid and
non-assessable.

     5.4 SEC Filings; Financial Statements. CKFR has timely filed all with the
SEC reports and other materials required to be filed by CKFR since September 28,
1995 (the "CheckFree SEC Reports"). The CheckFree SEC Reports (i) at the time
filed, complied in all material respects with the applicable requirements of the
securities laws and other applicable laws and (ii) did not, at the time they
were filed (or, if amended or superseded by a filing prior to the date of this
Master Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated in
such CheckFree SEC Reports or necessary in order to make the statements in such
CheckFree SEC Reports, in light of the circumstances under which they were made,
not misleading. No CheckFree Subsidiary is required to file any reports or make
filings with the SEC. The financial statements contained in the CheckFree SEC
Reports also comply in all material respects with the applicable published rules
and regulations of the SEC, and were prepared in accordance with Generally
Accepted Accounting Principles applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited interim statements, as permitted by Form
10-Q of the SEC), and fairly presented in all material respects the consolidated
financial position of CKFR and its subsidiaries as at the respective dates and
the consolidated results of operations and cash flows for the periods indicated.

     5.5 Absence of Certain Changes or Events. Since the filing of the most
recent of the CKFR SEC Reports, except as disclosed on Schedule 5.5, there have
been no events, changes, or occurrences which have had, or are reasonably likely
to have, individually or in the aggregate, a material adverse effect on
CheckFree, its business or its prospects.

                                       A-5
<PAGE>   31

     5.6 Legal Proceedings. Except as disclosed on Schedule 5.6, there is no
litigation instituted or pending, or, to the knowledge of CheckFree, threatened
(or unasserted but considered probable of assertion and which if asserted would
have at least a reasonable probability of an unfavorable outcome) against
CheckFree, or against any director, employee or employee benefit plan of
CheckFree, or against any Asset, interest, or right of CheckFree, seeking
damages in excess of $10 million, nor are there any orders of any regulatory
authorities, other governmental authorities, or arbitrators outstanding against
CheckFree, that are reasonably likely to have, individually or in the aggregate,
a material adverse effect on CheckFree, its business or its prospects.

     5.7 Statements True and Correct. No statement, certificate, instrument or
other writing furnished or to be furnished by CheckFree thereof to Bank pursuant
to this Master Agreement or any other document, agreement or instrument referred
to herein contains or will contain any untrue statement of material fact or will
omit to state a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading. None of the
information supplied or to be supplied by CheckFree for inclusion in any
documents to be filed with the SEC or any other regulatory Authority in
connection with the transactions contemplated hereby, will, at the respective
time such documents are filed, be false or misleading with respect to any
material fact, or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. All documents that CheckFree thereof is responsible for filing
with any regulatory authority in connection with the transactions contemplated
hereby will comply as to form in all material respects with the provisions of
applicable law.

     5.8 State Takeover Laws. The transactions contemplated by this Master
Agreement and the other Alliance Agreements do not require compliance with any
applicable "moratorium," "fair price," "business combination," "control share,"
or other anti-takeover laws, including Section 203 of the Delaware General
Corporation Law.

     5.9 Charter Provisions. CKFR has taken all action so that the entering into
of this Agreement and the consummation of the transactions contemplated by this
Master Agreement and the Alliance Agreements do not and will not result in the
grant of any rights to any person under the Certificate of Incorporation, Bylaws
or other governing instruments of CKFR or any of its subsidiaries, or restrict
or impair the ability of Bank to vote, or otherwise to exercise the rights of a
stockholder with respect to, shares of CKFR Common Stock that may be directly or
indirectly acquired or controlled by them.

     5.10 Rights Agreement. Except as Previously Disclosed, the entering into of
this Master Agreement and consummation of the transactions contemplated hereby
and by the Alliance Agreements do not and will not result in any person becoming
able to exercise any "Rights" as defined in and under the CheckFree Rights
Agreement or enabling or requiring the Rights to be separated from the shares of
CKFR Common Stock to which they are attached or to be triggered or to become
exercisable.

                                   ARTICLE 6

                     REPRESENTATIONS AND WARRANTIES OF BANK

conservatorship, moratorium, or similar laws affecting the enforcement of
creditors' rights generally and

                                       A-6
<PAGE>   32

except that the availability of the equitable remedy of specific performance or
injunctive relief is subject to the discretion of the court before which any
proceeding may be brought).

     (b) Neither the execution and delivery of this Master Agreement and the
related Alliance Agreements by Bank, nor the consummation by Bank of the
transactions contemplated hereby and thereby, nor compliance by Bank with any of

                              CERTAIN OTHER ITEMS

     7.1 Publicity. The form, substance and timing of any press release or other
public disclosure of matters related to this Master Agreement and the other
Alliance Agreements shall be mutually agreed to by CheckFree and Bank of America
in writing which consent shall not be unreasonably withheld, except to the
extent of disclosure for which CheckFree or Bank of America is required by law
to make, in which instance, the parties shall consult prior to making such
public disclosure.

     7.2 Transition Matters.

     (a) The Coordinating Committee. Each of Bank of America and CheckFree will
create a committee composed of senior officers to effect the various items set
forth in this Agreement as well as other items that may arise from time to time
in the preparation and finalization of definitive documents, exhibits and
schedules, the transition contemplated by the EBP Preliminary Services
Agreement, the EBP Transition Agreement or the implementation of the various
Alliance Agreements. This committee shall meet periodically. This committee may
create or empower various subcommittees to address specific items. To the

                                       A-7
<PAGE>   33

extent that there are disagreements regarding any matter that may arise with
respect to the matters contemplated by the Alliance Agreements, if the committee
is unable to reach a satisfactory resolution, the matter will be addressed by
the Chairman of CKFR and the Chief Technology Officer of Bank or their
designees.

     (b) Transition and Preparation Matters. The Parties acknowledge that during
the period commencing on the date of execution of this Master Agreement, and
continuing though the Closing, the Parties will be involved in intensive sharing
of information and data, both in an effort to complete the documentation
referred to above, but also to prepare for the actual implementation of those
various agreements and obligations. Specific and detailed transition plans and
schedules must be prepared. The Parties agree to devote sufficient personnel to
carry out this effort, to create and staff transition teams and take other steps
necessary to facilitate the smooth transition of functions and responsibilities
to CheckFree as contemplated by this Master Agreement and the other Alliance
Agreements.

     7.3 Allocation of Consideration. The Parties agree and acknowledge that the
grant of shares of CKFR Common Stock provided in Section 2.1 must be properly
valued and then allocated over a variety of assets and other rights and benefits
created pursuant to this Master Agreement and the other Alliance Agreements.
During the 120 day period following the date hereof, the parties shall work
together to determine both the appropriate value to be assigned to the Stock,
taking into consideration the various restrictions and limitations imposed on
the CKFR Stock under the Stock Restriction Agreement and Registration Rights
Agreement, and the allocation of the consideration among the assets, rights and
benefits. Within this 120-day period, Bank shall determine the appropriate value
to be assigned to the shares of CKFR Common Stock. If CheckFree disagrees with
the value so assigned, the matter shall be determined by a firm of
nationally-recognized certified public accountants selected and compensated by
Bank. Within this 120-day period, CKFR shall determine the appropriate
allocation of the consideration. If Bank disagrees with the value so assigned,
the matter shall be determined by a firm of nationally-recognized certified
public accountants selected and compensated by CheckFree.

     7.4 Confidentiality. The Parties acknowledge that during the course of the
transactions contemplated by this Master Agreement and the other Alliance
Agreements, each has received and will continue to receive sensitive commercial
information regarding the other and the business and affairs of the other that
has not been disclosed to the public and the disclosure of which would be
detrimental to the business and affairs of the other. While there may be
separate privacy and confidentiality obligations contained in the other Alliance
Agreements, which in the event of conflict shall control, the Parties generally
agree to respect the confidentiality of such sensitive commercial information.
The Parties will attempt to identify such confidential information or the types
of information to be treated in a confidential fashion. Each Party shall, and
shall cause its advisers and agents to, maintain the confidentiality of all such
information (the "Confidential Information") furnished to it by the other
concerning its businesses, operations, and financial positions and shall not use
such Confidential Information for any purpose except in as contemplated by this
Agreement, and shall not disclose such Confidential Information to any third
party without the prior written consent of the other. In the event that a Party
or any affiliate or representative of a Party, or any officer, director,
employee or representative thereof is requested or required by documents
subpoena, civil investigative demand, interrogatories, requests for information,
or other similar process to disclose any Confidential Information which
otherwise may not be disclosed except as set forth in the preceding sentence,
such Party will provide the other with prompt notice of such request, demand or
other similar process so that the Party may seek an appropriate protective order
or, if such request, demand or other similar process is not mandatory, waive
compliance with the provisions of this Section. The term "Confidential
Information" as to a Party does not include information which (i) becomes
generally available to the public other than as a result of disclosure by the
other Party in breach hereof, (ii) was available on a non-confidential basis
prior to its disclosure by the Party, including through disclosures by such
persons prior to the date of this Agreement, or (iii) becomes available to other
Party on a non-confidential basis from a source other than the Party, provided
that such source is not bound by a confidentially agreement with the Party.

     7.5 Arbitration.

     (a) Mandatory Arbitration. Any controversy or claim arising out of or
relating to this Master Agreement or the other Alliance Agreements (except to
the extent other dispute resolution procedures are specifically provided
therein), or the breach thereof, including claims for equitable relief, shall be
settled by arbitration in Atlanta, Georgia. The arbitration shall be
administered by the American Arbitration Association ("AAA") in accordance with
its Commercial Arbitration Rules, and shall be heard by a panel of three (3)
arbitrators selected in accordance with these Rules. After a demand for
arbitration is made, each party may conduct two (2) party and two (2) non-party
depositions and may further request discovery through up to thirty (30) document
requests, twenty (20) written interrogatories, and ten (10) requests for
admission, and/or such other further discovery as permitted by the arbitration
panel upon request and for good cause shown. The arbitrators may grant any
remedy or relief, including equitable relief, that they deem just and equitable,
except the arbitrators will have no authority to award punitive or other damages
not measured by the prevailing party's actual damages unless required by
statute. Each party shall be responsible for its own costs and expenses, except
that the arbitrators shall have the discretion to allocate the costs and
expenses of the Parties, including attorney's fees, as well as the compensation
and fees of the arbitrators, as the arbitrators may determine based upon the
position of the parties with respect to the matter in dispute, the outcome of
the arbitration, and such similar factors as the arbitrators may determine
equitable under the circumstances. Judgment on the award rendered by the
arbitrators may be entered in any court having jurisdiction thereof.

     (b) Interim Relief. If either party is in need of emergency relief prior to
the constitution of the arbitration panel, that party may apply to the AAA for
such emergency relief in accordance with its Optional Rules for Emergency
Measures of Protection. Pursuant to those Rules, the AAA shall appoint a single
emergency arbitrator to rule on emergency applications, which emergency
arbitrator may enter an interim award granting the relief and stating the
reasons therefor. After the panel is constituted, it may take whatever interim
measures it deems necessary, in accordance with Rule R-36, including the de
novoreview of any award or relief granted by the emergency arbitrator, either
upon the motion of a party or its own motion, and the emergency arbitrator shall
have no further power to act. The procedure outlined in this paragraph shall be
the sole mechanism for seeking interim relief, and any request for interim
measures addressed by a party to a judicial authority shall be deemed
incompatible with the agreement to arbitrate. The Parties hereto agree that
irreparable damage may occur in the event that any of the provisions of this
Master Agreement were not performed in accordance with its specific terms or was
otherwise breached. It is accordingly agreed that the Parties shall be entitled
to an injunction or injunctions to prevent breaches of this Master Agreement and
to enforce specifically the terms and provisions hereof.

     (c) Intellectual Property Claims. Intellectual property claims shall also
be subject to mandatory arbitration, except that questions concerning the
existence, validity, enforceability, and ownership of intellectual property
shall be decided by a special arbitrator, appointed by the AAA, who shall be
skilled in the technical and legal areas of intellectual property involved. The
findings of the special arbitrator shall be binding on the arbitration panel,
which shall then determine any damages or other relief to be awarded in
accordance thereunder. Such findings however, even if forming the basis for a
judgment filed in court, may not be relied upon by any other party, nor shall
the judgment act to collaterally estop the party adversely affected by the
finding or judgment from contesting the same or similar claim, or from raising
the same or similar defenses, in any proceeding involving any entity not a party
to this Master Agreement.

     (d) Binding Effect of Arbitration Decisions. Any decision by the arbitrator
or arbitrators pursuant hereto shall be final and binding as to any matters
submitted to the arbitrator, and may be enforced by judicial proceeding having
jurisdiction over the Party subject to such decision.

     condition been known, such Party would not have entered into this
     Agreement.

          (c) Legal Proceedings. No court or governmental or regulatory
     authority of competent jurisdiction shall have enacted, issued or

provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable. The terms of this subsection shall not be
applied, however, if the result would, in the reasonable judgment of either
Party, deprive it of a material financial or business benefit of the
transaction, such that, had the unenforceability been known, such Party would
not have entered into this Agreement.

portions thereof) ending on or prior to the Closing Date. The Purchaser shall be
liable for and shall pay all Taxes (whether assessed or unassessed) applicable
to the Acquired Operations, the Acquired Assets or the Assumed Liabilities, in
each case attributable to periods (or portions thereof) beginning after the

Taxes) shall be apportioned on a daily basis. The term "Taxes" shall not include
income taxes, which shall in each case be the responsibility of each party
according to law.

recording fees, transfer or similar Tax directly attributable to the sale or

the transactions contemplated by this Agreement and which accrue or are
attributable to a period ending on or prior to the Closing Date.

     (c) Each party hereto shall provide reimbursement for any Tax which is the
responsibility of such party in accordance with the terms of this Section 1.6
and which is paid by the other party. Within a reasonable time prior to the
payment of any such Tax, the party paying such Tax shall give notice to the
other party of the Tax payable and the portion which is the liability of each
party, although failure to do so will not relieve the other party from its
liability hereunder.
