Dear Stockholders:

     You are cordially invited to attend a special meeting of our stockholders
to be held at our headquarters at 90 Merrick Avenue, Suite 501, East Meadow, New
York on             , 1999 at 8:00 a.m., Eastern time. At the meeting, you will
be asked to consider and vote upon a proposal to approve and adopt a
reorganization agreement with Healtheon Corporation and approve a merger that
will cause MEDE AMERICA to become a wholly owned subsidiary of a new parent
company called Healtheon/WebMD Corporation.

     In the merger, you will receive 0.6593 shares of Healtheon/WebMD common
stock for each share of MEDE AMERICA common stock you own, subject to adjustment
if the lower of the ten-day average closing price of Healtheon common stock for
the period ending on July 30, 1999 and for the period ending two days prior to
the stockholders' meeting is greater than $63.70 or less than $38.68. This
adjustment to the exchange ratio is more fully described in the section entitled
"Structure of the reorganization and conversion of MEDE AMERICA common stock" on
page 96 of this proxy statement/prospectus. On             , 1999, Healtheon
common stock closed at $     per share.

     The attached proxy statement/prospectus also includes information about a
proposed Healtheon-WebMD reorganization. While your vote is not required for
that reorganization, you should be aware that if that reorganization is
completed, WebMD will also become a wholly owned subsidiary of Healtheon/ WebMD.

     AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS UNANIMOUSLY APPROVED
THE MERGER AND CONCLUDED THAT IT IS IN THE BEST INTERESTS OF MEDE AMERICA AND
ITS STOCKHOLDERS. YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE
"FOR" THIS TRANSACTION.

     Attached is a notice of special meeting of stockholders and a proxy
statement/prospectus relating to the merger. The proxy statement/prospectus
provides you with detailed information concerning Healtheon and the merger. We
encourage you to read it carefully. IN PARTICULAR, YOU SHOULD READ CAREFULLY THE
DISCUSSION IN THE SECTION ENTITLED "RISK FACTORS" ON PAGE 28 OF THIS PROXY
STATEMENT/PROSPECTUS.

     We cordially invite you to attend the meeting. However, whether or not you
plan to attend the meeting, please complete, sign and date the enclosed proxy
and return it to us in the enclosed envelope. If you attend the meeting, you may
vote in person if you wish, even though you have previously returned your proxy.

           QUESTIONS AND ANSWERS FOR HEALTHEON AND WEBMD STOCKHOLDERS

Q: WHAT IS THE HEALTHEON-WEBMD REORGANIZATION?

A: The boards of directors of Healtheon and WebMD have voted to combine the
   businesses of Healtheon and WebMD. To combine the companies, a new parent
   company will be formed, called Healtheon/WebMD Corporation. Healtheon will
   merge with a subsidiary of Healtheon/WebMD, and WebMD will merge with another
   subsidiary of Healtheon/ WebMD, resulting in Healtheon and WebMD each
   becoming subsidiaries of Healtheon/ WebMD. (See diagrams on page 9).

   After the Healtheon-WebMD reorganization, assuming conversion of all shares
   of WebMD preferred stock into common stock and completion of the proposed
   combination of Healtheon and MEDE AMERICA which is discussed further below,
   the former stockholders of Healtheon will own approximately 49.5%, the former
   stockholders of WebMD will own approximately 44.4% and the former
   stockholders of MEDE AMERICA will own approximately 6.1% of Healtheon/WebMD.

   For a more complete description of the Healtheon-WebMD reorganization, see
   the section entitled "The Healtheon-WebMD reorganization" on page 50.

Q: WHAT IS THE NEW PARENT COMPANY, HEALTHEON/ WEBMD?

A: Healtheon/WebMD is a new parent corporation formed to facilitate the
   combination of the businesses of Healtheon and WebMD. It is expected that
   Healtheon/WebMD common stock will trade on the Nasdaq National Market under
   the trading symbol "HLTH" in lieu of Healtheon common stock. Initially, the
   businesses of Healtheon and WebMD will remain in the subsidiaries of
   Healtheon/ WebMD, but Healtheon/WebMD management will control the combined
   entities.

Q: WHAT WILL HEALTHEON STOCKHOLDERS RECEIVE IN THE REORGANIZATION?

A: When the reorganization is completed, Healtheon stockholders will receive one
   share of Healtheon/WebMD common stock in exchange for each share of Healtheon
   common stock. However, Healtheon stockholders will not be required to give up
   their stock certificates because old Healtheon stock certificates will
   represent their interest in Healtheon/ WebMD. PLEASE DO NOT SEND YOUR
   HEALTHEON STOCK CERTIFICATES.

   Holders of options or warrants to purchase shares of Healtheon common stock
   will hold options or warrants, as appropriate, to purchase shares of
   Healtheon/WebMD common stock after completion of the reorganization.

Q: WHAT WILL WEBMD COMMON STOCKHOLDERS RECEIVE IN THE REORGANIZATION?

A: When the Healtheon-WebMD reorganization is completed, holders of each series
   of WebMD common stock will receive 1.815 shares of Healtheon/WebMD common
   stock in exchange for each share of WebMD common stock, except for those
   holders who exercise dissenters' rights under Georgia law. No fractional
   shares will be issued. WebMD common stockholders will receive cash based on
   the market price of Healtheon common stock instead of any fractional share.

   Example: If a WebMD common stockholder owns 100 shares, then after the
   reorganization the stockholder will receive 181 shares of Healtheon/WebMD
   common stock and a check for the market value of the 0.5 fractional share of
   Healtheon/WebMD common stock.

   Holders of options or warrants to purchase shares of WebMD common stock will
   hold options or warrants as appropriate to purchase shares of Healtheon/WebMD
   common stock after completion of the reorganization.

   For a more complete description of what WebMD stockholders will receive in
   the Healtheon-WebMD reorganization, see the section entitled "Structure of
   the Healtheon-WebMD reorganization and conversion of WebMD common stock and
   Healtheon

                                        1
<PAGE>   12

   common stock" on page 9. PLEASE DO NOT SEND YOUR WEBMD STOCK CERTIFICATES AT
   THIS TIME.

Q: WHAT WILL WEBMD PREFERRED STOCKHOLDERS RECEIVE IN THE REORGANIZATION?

A. When the reorganization is completed, WebMD's preferred stockholders will
   continue to hold their WebMD preferred stock which will then represent
   preferred stock of the WebMD subsidiary of Healtheon/WebMD. The preferred
   stock will continue to be convertible into WebMD common stock and not into
   publicly traded common stock of Healtheon/WebMD, and will continue to have
   all of the other preferences and rights currently applicable to the WebMD
   preferred stock. As a result of conversion agreements and voting agreements
   that have been signed by the holders of a majority of the outstanding shares
   of WebMD's Series C, D, E and F preferred stock, those Series of preferred
   stock will be converted into WebMD common stock prior to the effective time
   of the WebMD merger and thus will receive 1.815 shares of Healtheon common
   stock for each share of WebMD common stock received in the preferred stock
   conversion. In the case of the Series A preferred stock and Series B
   preferred stock, if the holders of a majority of either Series elect to
   convert into WebMD common stock prior to the WebMD merger, then the entire
   Series will be automatically converted. In the case of the Series A preferred
   stock, any holder may elect to convert into common stock prior to the WebMD
   merger.

   Holders of options and warrants for WebMD preferred stock (other than its
   Series A and B preferred stock) will hold options and warrants as appropriate
   to purchase shares of Healtheon/WebMD common stock after the completion of
   the reorganization. Options and warrants for WebMD Series A and B preferred
   stock (other than options to acquire Series B preferred stock under the
   Sapient Option Plan) will remain exercisable for WebMD Series A and Series B
   preferred stock after the reorganization, unless a majority of the holders of
   the applicable Series elects to cause the entire series to be converted into
   WebMD common stock prior to the effective time of the WebMD merger, in which
   case options and warrants to purchase such series shall become by their terms
   options and warrants for Healtheon/WebMD common stock. Upon completion of the
   reorganization, options granted under the Sapient Option Plan to acquire
   Series B preferred stock will become exercisable for Healtheon/WebMD common
   stock.

Q: WHAT IS THE MEDE AMERICA REORGANIZATION?

A: Healtheon has also agreed to a reorganization with MEDE AMERICA, which is
   described in this proxy statement/prospectus. The Healtheon-WebMD
   reorganization does not depend on Healtheon's reorganization with MEDE
   AMERICA. However, you should be aware that if the MEDE AMERICA reorganization
   is completed, MEDE AMERICA will become another subsidiary of the combined
   Healtheon/WebMD, and MEDE AMERICA stockholders will become stockholders of
   Healtheon/WebMD.

   This proxy statement/prospectus is also being sent to stockholders of MEDE
   AMERICA. Unless stated otherwise, information provided in this proxy
   statement/prospectus assumes completion of the MEDE AMERICA reorganization.
   Where appropriate, we have indicated where information pertaining to
   Healtheon and WebMD does not give effect to the merger with MEDE AMERICA.

Q: DOES THE BOARD OF DIRECTORS OF HEALTHEON RECOMMEND VOTING IN FAVOR OF THE
   HEALTHEON-WEBMD REORGANIZATION?

A: Yes. After careful consideration, Healtheon's board of directors unanimously
   recommends that its stockholders vote in favor of the proposed
   Healtheon-WebMD reorganization and the issuance of shares of Healtheon/ WebMD
   common stock to the stockholders of WebMD in the WebMD merger.

Q: DOES THE BOARD OF DIRECTORS OF WEBMD RECOMMEND VOTING IN FAVOR OF THE
   HEALTHEON-WEBMD REORGANIZATION?

A: Yes. After careful consideration, WebMD's board of directors unanimously
   recommends that its stockholders vote in favor of the Healtheon-WebMD
   reorganization agreement and the proposed WebMD merger.

Q: ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
   HEALTHEON-WEBMD REORGANIZATION?

A: Yes. In evaluating the Healtheon-WebMD reorganization, you should carefully
   consider the factors discussed in the section entitled "Risk Factors" on page
   28.

Q: WHAT DO I NEED TO DO NOW?

A: Mail your signed proxy card in the enclosed return envelope as soon as
   possible so that your shares may be represented at your meeting. If you do
   not include instructions on how to vote your properly signed proxy, your

Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE?

A: If you are a Healtheon stockholder and want to change your vote, send the
   secretary of Healtheon a later-dated, signed proxy card before the Healtheon
   meeting or attend the meeting in person. You may also revoke your proxy by
   sending written notice to the secretary of Healtheon before the meeting.
   Healtheon stockholders who have signed voting agreements may not revoke the
   proxies given by them in the voting agreements.

   For a more complete description of how to change your vote as a Healtheon
   stockholder, see the section entitled "Proxies" on page 44.

   If you are a WebMD stockholder and want to change your vote, send the
   secretary of WebMD a later-dated, signed proxy card before the WebMD meeting
   or attend the meeting in person. You may also revoke your proxy by sending
   written notice to the secretary of WebMD before the meeting. WebMD
   stockholders who have signed voting or conversion agreements may not revoke
   the proxies given by them in the voting or conversion agreements.

   For a more complete description of how to change your vote as a WebMD
   stockholder, see the section entitled "Proxies" on page 46.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. After the reorganization is completed, we will send you written
   instructions for exchanging your stock certificates for Healtheon/WebMD stock
   certificates.

Q: WHEN DO YOU EXPECT THE HEALTHEON-WEBMD REORGANIZATION TO BE COMPLETED?

A: We are working toward completing the Healtheon-WebMD reorganization as
   quickly as possible. We hope to complete the reorganization during the third
   calendar quarter of 1999.

              QUESTIONS AND ANSWERS FOR MEDE AMERICA STOCKHOLDERS

Q: WHAT IS THE MEDE AMERICA REORGANIZATION?

A: The boards of directors of Healtheon and MEDE AMERICA have voted to combine
   the businesses of Healtheon and MEDE AMERICA. To combine the companies, a new
   parent company will be formed, called Healtheon/WebMD. Healtheon will merge
   with a subsidiary of Healtheon/WebMD, and MEDE AMERICA will merge with
   another subsidiary of Healtheon/WebMD, resulting in each of Healtheon and
   MEDE AMERICA becoming subsidiaries of Healtheon/WebMD. The MEDE AMERICA
   reorganization does not depend on the Healtheon-WebMD reorganization. (See
   diagrams on page 9.)

   For a more complete description of the reorganization, see the section
   entitled "The MEDE AMERICA reorganization" on page 86.

Q: WHAT IS THE NEW PARENT COMPANY, HEALTHEON/ WEBMD?

A: Healtheon/WebMD is a new parent corporation formed to facilitate the
   combination of the businesses of Healtheon, WebMD and MEDE AMERICA. It is
   expected that Healtheon/ WebMD common stock will trade on the Nasdaq National
   Market in lieu of Healtheon common stock under the trading symbol "HLTH."
   Initially, the businesses of Healtheon, WebMD and MEDE AMERICA will remain in
   the subsidiaries of Healtheon/ WebMD, but Healtheon/WebMD management will
   control the combined entities.

Q: WHAT WILL MEDE AMERICA STOCKHOLDERS RECEIVE IN THE REORGANIZATION?

A: When the reorganization is completed, MEDE AMERICA stockholders will receive,
   subject to adjustment in certain circumstances described below, 0.6593 shares
   of Healtheon/ WebMD common stock in exchange for each share of MEDE AMERICA
   common stock. Healtheon/WebMD will not issue fractional shares. Adjustments
   to the exchange ratio are based on the lower of the average closing price of
   Healtheon common stock for the ten day period ending July 30, 1999 or two
   business days before the MEDE AMERICA stockholders meeting. MEDE AMERICA
   stockholders will receive cash based on the market price of Healtheon/WebMD
   common stock instead of any fractional share.

   Example: If the lower average Healtheon closing sale price is $50 and you own
   100 shares of MEDE AMERICA common stock, then after the reorganization you
   will receive 65 shares of Healtheon/WebMD common stock and a check for the
   market value of the 0.93 fractional share of Healtheon/WebMD common stock.

   If the average closing sale price of Healtheon common stock is less than
   $38.68 during the ten consecutive trading day period ending July 30, 1999,
   Healtheon may adjust the exchange ratio to an amount calculated by dividing
   25.50 by such average closing sale price. This adjustment would increase the
   number of shares issued to MEDE AMERICA stockholders in the reorganization.
   If Healtheon does not elect to adjust the exchange ratio, MEDE AMERICA has
   the right to terminate the reorganization agreement at such time.

   Example: If the average Healtheon closing sale price is $35 for the ten
   consecutive days ending July 30, 1999 and you own 100 shares of MEDE AMERICA
   common stock, and if Healtheon adjusts the exchange ratio, then the new
   exchange ratio is 0.7286. You will receive 72 shares of Healtheon/WebMD
   common stock and a check for the market value of the 0.86 fractional share of
   Healtheon/WebMD common stock. We calculated the exchange ratio by dividing
   $25.50 by $35. If the average Healtheon closing sale price two days prior to
   the special meeting is higher than $35, the exchange ratio remains 0.7286.
   However, if the average price is lower than $35, then Healtheon may elect to
   increase the exchange ratio to an amount equal to $25.50 divided by such
   lower average price.

   If the average closing sale price of Healtheon common stock is higher than
   $63.70 during both ten consecutive trading day periods, MEDE AMERICA may
   adjust the exchange ratio to an amount calculated by dividing $42 by the
   lower average closing sale price. This
                                        5
<PAGE>   16

   adjustment would decrease the number of shares issued to MEDE AMERICA
   stockholders in the reorganization. If MEDE AMERICA does not elect to adjust
   the exchange ratio, Healtheon has the right to terminate the reorganization
   agreement prior to the MEDE AMERICA stockholder meeting.

   Example: If the lower average Healtheon closing sale price is $65 and you own
   100 shares of MEDE AMERICA common stock, and if MEDE AMERICA adjusts the
   exchange ratio, then the new exchange ratio is 0.6462. You will receive 64
   shares of Healtheon/WebMD common stock and a check for the market value of
   the 0.62 fractional share of Healtheon/WebMD common stock. We calculated the
   exchange ratio by dividing 42 by $65.

   Holders of options or warrants to purchase shares of MEDE AMERICA common
   stock will hold options or warrants as appropriate to purchase shares of
   Healtheon/WebMD common stock after completion of the reorganization.

   Healtheon's stock price has been volatile. As an example, the following table
   sets forth the high and low closing sale prices per share of Healtheon common
   stock on the Nasdaq National Market during the indicated months.

   For a more complete description of what you will receive in the
   reorganization, see the section entitled "Structure of the MEDE AMERICA
   reorganization and conversion of MEDE AMERICA common stock" on page 96.

Q: DOES THE BOARD OF DIRECTORS OF MEDE AMERICA RECOMMEND VOTING IN FAVOR OF THE
   MEDE AMERICA REORGANIZATION?

A: Yes. After careful consideration, MEDE AMERICA's board of directors
   unanimously recommends that its stockholders vote in favor of the
   reorganization agreement and the proposed reorganization.

   For a more complete description of the recommendation of the board of
   directors of MEDE AMERICA, see the sections entitled "MEDE AMERICA's reasons
   for the MEDE AMERICA reorganization" on page 88 and "Recommendation of MEDE
   AMERICA's board of directors" on page 90.

Q: ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE MEDE
   AMERICA REORGANIZATION?

A: Yes. For example, after the exchange ratio is set, the number of shares of
   Healtheon/ WebMD common stock that MEDE AMERICA stockholders will receive may
   not change even if the market price of Healtheon common stock increases or
   decreases before the completion of the reorganization. We urge you to obtain
   current market quotations of Healtheon common stock and MEDE AMERICA common
   stock.

   In evaluating the reorganization, you should carefully consider these and
   other factors discussed in the section entitled "Risk Factors" on page 28.

Q: WHAT DO I NEED TO DO NOW?

A: Mail your signed proxy card in the enclosed return envelope as soon as
   possible so that your shares may be represented at your meeting. If you do
   not include instructions on how to vote your properly signed proxy, your
   shares will be voted "FOR" approval and adoption of the reorganization
   agreement and approval of the reorganization.

   For a more complete description of voting at the meeting, see the section
   entitled "Proxies" on page 49.

                                        6
<PAGE>   17

Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE?

A: If you want to change your vote, send the secretary of MEDE AMERICA a
   later-dated, signed proxy card before the meeting or attend the meeting in
   person. You may also revoke your proxy by sending written notice to the
   secretary of MEDE AMERICA before the meeting.

   vote by following the information provided to you by your broker.

   For a more complete description of voting shares held in "street name," see
   the section entitled "Proxies" on page 49.

Q: SHOULD I SEND IN MY MEDE AMERICA STOCK CERTIFICATES NOW?

   instructions for exchanging your MEDE AMERICA stock certificates for
   Healtheon/WebMD stock certificates.

Q: WHEN DO YOU EXPECT THE MEDE AMERICA REORGANIZATION TO BE COMPLETED?

A: We are working toward completing the MEDE AMERICA reorganization as quickly

   stockholders are urged to consult their own tax advisor to determine their
   particular tax consequences.

                 SUMMARY OF THE HEALTHEON-WEBMD REORGANIZATION

THE HEALTHEON-WEBMD REORGANIZATION

     In the Healtheon-WebMD reorganization, Healtheon will merge with a
subsidiary of a new parent company, called Healtheon/WebMD, and WebMD will merge
with another subsidiary of Healtheon/WebMD, resulting in Healtheon and WebMD
each becoming subsidiaries of Healtheon/WebMD. Following the reorganization,
Healtheon stockholders will be deemed to have automatically exchanged their
shares for shares of Healtheon/WebMD common stock, and WebMD common stockholders
will be entitled to exchange their shares for shares of Healtheon/WebMD common
stock.

     The Healtheon-WebMD reorganization agreement is attached to this proxy
statement/prospectus as Annex A. We encourage you to read it carefully. The
Healtheon-WebMD reorganization agreement is more fully discussed on page 78.
(See diagrams on page 9).

     We believe the Healtheon-WebMD reorganization will provide Healtheon/WebMD
with the opportunity to realize several benefits, including:

     - combining WebMD's strong brand recognition and strategic relationships
       with Healtheon's e-commerce transaction platform and industry
       relationships will enable Healtheon/WebMD to move decisively toward the
       goal of achieving critical mass in the healthcare industry with a
       comprehensive, integrated Internet-based solution

     - expanding each company's connected network of customers and partners.
       Healtheon/WebMD is expected to offer connectivity and transactions for
       physicians, consumers and healthcare institutions over a network
       consisting of approximately 540 payers, 180,000 physicians, 1,100
       hospitals, 42,000 pharmacies, 10,000 dentists and 200 affiliate partners,
       assuming completion of the MEDE AMERICA reorganization

     - increasing each company's transaction volume

     - broadening each company's offerings of Internet-based healthcare-related
       services and creating enhanced cross-selling opportunities

     - increasing the speed of Internet transaction processing by streamlining
       inefficient manual and paper-based processes

     - creating a strong combined management team

     The reorganization could harm Healtheon/ WebMD in a number of ways,
including:

     - the uncertainty of key third party relationships

     - the strain associated with rapid and significant expansion of operations

     - the loss of key contractual rights if consents to the reorganization
       cannot be obtained

     - the inability of computer systems to accommodate increased use while
       maintaining performance

     The potential benefits of the Healtheon-WebMD reorganization may not be
achieved. For a more complete description of the risks, see the sections
entitled "Risk Factors" on page 28, and "Joint reasons for the Healtheon-WebMD
reorganization" on page 52.

CONDITIONS TO COMPLETION OF THE HEALTHEON-WEBMD REORGANIZATION

     Healtheon's and WebMD's respective obligations to complete the
Healtheon-WebMD reorganization are subject to the satisfaction or waiver of
closing conditions. The conditions that must be satisfied or waived before the
completion of the reorganization include the following, subject to exceptions
and qualifications:

     - the reorganization must be approved by Healtheon stockholders and the
       reorganization agreement must be approved and adopted and the WebMD
       merger must be approved by WebMD stockholders

     - no injunction or order preventing the completion of the Healtheon-WebMD
       reorganization can be in effect

     - the applicable waiting periods under antitrust laws must expire or be
       terminated

     - Healtheon and WebMD must each receive an opinion of tax counsel to the
       effect that

                                       10
<PAGE>   21

       the Healtheon-WebMD reorganization will qualify as a transaction in which
       no gain or loss will be recognized for U.S. income tax purposes upon the
       receipt of Healtheon/ WebMD shares

     - the shares of Healtheon/WebMD common stock to be issued in the Healtheon-
       WebMD reorganization must have been approved for listing on Nasdaq
       National Market, subject to notice of issuance

     - Healtheon's and WebMD's respective representations and warranties in the
       Healtheon-WebMD reorganization agreement must be true and correct,
       subject to materiality qualifications

     - no material adverse effect shall have occurred with respect to Healtheon
       or WebMD

     - Healtheon and WebMD must have complied in all material respects with
       their respective agreements and covenants in the Healtheon-WebMD
       reorganization agreement

     - no stockholder (taken together with its affiliates) of WebMD shall
       beneficially own, or have the right to beneficially own, at any time in
       the future, 40% or more of the outstanding shares of WebMD stock on a
       fully diluted, as converted basis

     - no more than 0.66% of the shares of WebMD capital stock on a fully
       diluted, as converted basis shall have perfected rights of appraisal or
       dissenters rights with respect to the WebMD merger

     - WebMD's legal counsel shall have delivered a legal opinion to Healtheon

     - WebMD shall have provided Healtheon with reasonably satisfactory evidence
       that, with limited exceptions, all material rights of stockholders and
       obligations of WebMD under any stockholder agreement shall have
       terminated

     - WebMD shall have received an additional investment from Microsoft
       pursuant to the terms of the Investment Agreement dated May 12, 1999 in
       an amount equal to $150 million

     - The Shareholder Agreement with Microsoft shall be in full force and
       effect

     If either Healtheon or WebMD waives any conditions, the companies will each
consider the facts and circumstances at that time and make a determination
whether a resolicitation of proxies from stockholders is appropriate.

     The Healtheon-WebMD reorganization is not conditioned upon completion of
the MEDE AMERICA reorganization.

     For a more complete description of the conditions to completion of the
reorganization, see the section entitled "Conditions to completion of the
Healtheon-WebMD reorganization" on page 80.

VOTE REQUIRED FOR APPROVAL

     The holders of a majority of the outstanding shares of Healtheon common
stock must approve the Healtheon merger and the issuance of Healtheon/WebMD
common stock in the WebMD merger. Healtheon stockholders are entitled to cast
one vote per share of Healtheon common stock owned as of [               ] 1999,
the record date. Healtheon stockholders holding [     ]% of outstanding
Healtheon common stock as of the record date have agreed to vote in favor of the
Healtheon merger. Directors and officers of Healtheon collectively beneficially
owned approximately [     ]% of the outstanding Healtheon common stock as of the
record date.

     A majority of the votes entitled to be cast by the holders of WebMD's (i)
common stock and Series A preferred stock, (ii) Series B common stock, and (iii)
Series C and E common stock, each voting as separate voting groups, must vote in
favor of the reorganization agreement and the WebMD merger. As a result of
voting agreements that have been signed by WebMD directors, executive officers
and affiliates and the conversion agreements that have been signed by some
holders of WebMD's preferred stock, these votes are assured.

     For a more complete description of the vote required for approval of the
Healtheon-WebMD reorganization see the sections entitled "Vote and quorum
required" on page 43 and "Votes required; voting agreements; conversion
agreements" on page 45.

TERMINATION OF THE HEALTHEON-WEBMD REORGANIZATION AGREEMENT

     The Healtheon-WebMD reorganization agreement may be terminated before
completion:

     - by mutual consent of Healtheon and WebMD

     - by Healtheon or WebMD, if the Healtheon-WebMD reorganization is not
       completed before December 15, 1999, except that this right to terminate
       is not available to any party whose material breach of the agreement has
       resulted in the failure of the Healtheon-WebMD reorganization to occur on

       and Chief Executive Officer of WebMD, will join the Healtheon/WebMD Board
       of Directors as one of the representatives of WebMD and W. Michael Long,

       in the combined companies.

     - Mr. Arnold has agreed to waive any vesting of his unvested stock options
       granted under his employment agreement that would occur upon the
       completion of the reorganization. However, if Mr. Arnold is terminated
       other than for cause by Healtheon/ WebMD following the reorganization,
       then all options granted to him pursuant to his employment agreement will
       immediately vest and become fully exercisable on the date of such
       termination.

     - Following the Healtheon-WebMD reorganization, Healtheon/WebMD will expand
       a strategic relationship with Microsoft, a current stockholder of WebMD
       that will own approximately 17% of the Healtheon/ WebMD common stock

                   SUMMARY OF THE MEDE AMERICA REORGANIZATION

THE MEDE AMERICA REORGANIZATION

     In the reorganization, MEDE AMERICA will merge with a wholly owned
subsidiary of Healtheon/WebMD, and as a result MEDE AMERICA will become a wholly
owned subsidiary of Healtheon/WebMD.

     The reorganization agreement is attached to this proxy statement/prospectus
as Annex B. We encourage you to read the reorganization agreement carefully. The
reorganization agreement is more fully discussed on page 101.

     We believe the reorganization will provide the combined company with the
opportunity to realize several benefits, including:

     - expanding each company's connected network of customers and partners,
       accelerating our efforts towards achieving critical mass in the
       healthcare industry and strengthening our competitive position

     - enabling us to migrate MEDE AMERICA's large, installed base of prominent
       healthcare institutions and professionals to Healtheon's Internet-based
       platform and front-end Web connectivity

     - increasing our transaction volume

     - broadening our offerings of Internet-based financial and clinical
       transactions services, and creating enhanced cross-selling opportunities

     - facilitating electronic prescriptions among physicians, consumers and
       pharmacies because of our expanded connectivity

     - creating a strong combined management team

     There are potential risks to the reorganization, including:

     - technical, operational, regulatory and strategic challenges to
       integrating MEDE AMERICA and Healtheon

     - the loss of contractual rights by MEDE AMERICA as a result of the
       reorganization

     - volatility of Healtheon's stock price affecting the ability of MEDE
       AMERICA stockholders to realize the value of the merger consideration as
       measured prior to closing.

     - the additional risks relating to the combined company's business

     The potential benefits of the reorganization may not be achieved. See the
section entitled "Risk Factors" on page 28, and "MEDE AMERICA's reasons for the
MEDE AMERICA reorganization" on page 88.

CONDITIONS TO COMPLETION OF THE MEDE AMERICA REORGANIZATION

     Healtheon's and MEDE AMERICA's respective obligations to complete the
reorganization are subject to the satisfaction or waiver of closing conditions.
The conditions that must be satisfied or waived before the completion of the
merger include the following, subject to exceptions and qualifications:

     - the reorganization agreement must be approved and adopted and the merger
       must be approved by MEDE AMERICA stockholders

     - the applicable waiting periods under antitrust laws must expire or be
       terminated

     - no injunction or order preventing the completion of the reorganization
       may be in effect

     - Healtheon and MEDE AMERICA must each receive an opinion of tax counsel to
       the effect that the reorganization will qualify as a transaction in which
       no gain or loss will be recognized for U.S. federal income tax purposes
       upon the receipt of Healtheon/WebMD shares

     - the shares of Healtheon/WebMD common stock to be issued to MEDE AMERICA
       stockholders in the reorganization must have been approved for listing on
       Nasdaq

     - our respective representations and warranties in the reorganization
       agreement must be true and correct

     - no material adverse effect shall have occurred with respect to Healtheon
       or MEDE AMERICA

                                       16

     - we must have complied in all material respects with our respective
       agreements in the reorganization agreement

     - Healtheon must obtain the consent of its current registration rights
       holders to grant registration rights to the parties to the registration
       rights agreement

     - MEDE AMERICA must terminate all registration rights of its stockholders
       and all rights of its stockholders to appoint nominees to its board of
       directors

     If either Healtheon or MEDE AMERICA waives any conditions, we will each
consider the facts and circumstances at that time and make a determination as to
whether a resolicitation of proxies from stockholders is appropriate.

     The MEDE AMERICA reorganization is not conditioned upon the completion of
the Healtheon-WebMD reorganization.

     For a more complete description of the conditions to completion of the
merger, see the section entitled "Conditions to completion of the MEDE AMERICA

     - by mutual consent of Healtheon and MEDE AMERICA

     - by Healtheon or MEDE AMERICA, if the merger is not completed by September
       30, 1999, except that the right to terminate the reorganization agreement
       is not available to any party whose action or failure to act has resulted
       in the failure of the merger to occur on or before September 30, 1999,
       and such action or failure to act constitutes a material breach of the
       reorganization agreement

     - by Healtheon or MEDE AMERICA, if a final court order prohibiting the
       merger is issued and is not appealable

     - by Healtheon or MEDE AMERICA, if the MEDE AMERICA stockholders do not
       approve and adopt the reorganization agreement and approve the merger at
       the MEDE AMERICA special meeting

     - by Healtheon, if the MEDE AMERICA board, fails to recommend that MEDE
       AMERICA stockholders approve and adopt the reorganization agreement

     - by Healtheon, if the MEDE AMERICA board makes any recommendation or
       approval of extraordinary transactions involving MEDE AMERICA and a party
       other than Healtheon, such as a merger or a sale of significant assets

     MEDE AMERICA is entitled to adjust the exchange ratio in the reorganization

TERMINATION FEE

     If the reorganization agreement is terminated because MEDE AMERICA
stockholders do not approve and adopt the reorganization agreement and approve
the merger, or if the reorganization is not completed by September 30, 1999,
MEDE AMERICA may be obligated to pay Healtheon a termination fee of $15 million.
For MEDE AMERICA to become obligated to pay Healtheon the termination fee, an
extraordinary transaction of the nature specified in the reorganization
agreement involving MEDE AMERICA and a party other than Healtheon must be
publicly proposed before the termination of the reorganization agreement.
Furthermore, for the termination fee to become payable, MEDE AMERICA must enter
into an agreement for or complete an extraordinary transaction of the nature
specified in the reorganization agreement within 12 months following termination
of the reorganization agreement.

     In addition, subject to qualifications, MEDE AMERICA will pay Healtheon a
termination fee of $15 million if the reorganization agreement is terminated
because MEDE AMERICA's board of directors takes either of the following actions:

     - fails to recommend that MEDE AMERICA stockholders approve and adopt the
       reorganization agreement

     - makes any recommendation or approval of extraordinary transactions
       involving MEDE AMERICA and a party other than Healtheon, such as a merger
       or a sale of significant assets

     For a more complete description of the payment of the termination fee, see
the section entitled "Payment of termination fee" on page 107.

directors of MEDE AMERICA determines, in its reasonable judgement, to be more
favorable to MEDE AMERICA than the terms of the reorganization with Healtheon.

     MEDE AMERICA has agreed to promptly inform Healtheon as to any Acquisition
Proposal, request for non-public information or inquiry which MEDE AMERICA
believes would lead to an Acquisition Proposal. MEDE AMERICA has agreed to
inform Healtheon of the status and details of any Acquisition Proposal.

              SELECTED HISTORICAL AND SELECTED UNAUDITED PRO FORMA
                       CONDENSED COMBINED FINANCIAL DATA

     The following selected historical financial data of Healtheon, WebMD and
MEDE AMERICA has been derived from their respective historical financial
statements, and should be read in conjunction with those financial statements
and the related notes which are included elsewhere in this proxy
statement/prospectus. The selected unaudited pro forma condensed combined
financial data of Healtheon, WebMD and MEDE AMERICA are derived from the
unaudited pro forma condensed combined financial information, which gives effect
to the transactions as purchases, and should be read in conjunction with the
unaudited pro forma condensed combined financial information and related notes,
which are included elsewhere in this prospectus/proxy statement.

     For pro forma purposes, Healtheon's historical statement of operations for
the year ended December 31, 1998, WebMD's statement of operations for the year
ended December 31, 1998 (after giving effect to the acquisition of Sapient
Health Network and Direct Medical Knowledge) and MEDE AMERICA's statement of
operations for the twelve months ended December 31, 1998 (after giving effect to
the acquisition of Healthcare Interchange, Inc.) have been combined to give
effect to the reorganizations as if they had occurred on January 1, 1998.
Healtheon's historical statement of operations for the three months ended March
31, 1999, WebMD's historical statement of operations for the three months ended
March 31, 1999 and MEDE AMERICA's historical statement of operations for the
three months ended March 31, 1999 have been combined to give effect to the
reorganizations as if they had occurred on January 1, 1999.

     The unaudited pro forma combined condensed balance sheet data assumes that
the WebMD and MEDE AMERICA reorganizations took place as of March 31, 1999 and
combine Healtheon's, WebMD's and MEDE AMERICA's historical balance sheets at
that date.

     The total estimated purchase prices of the WebMD and MEDE AMERICA
reorganizations have been allocated on a preliminary basis to assets and
liabilities based on management's best estimates of their fair value with the
excess over the net tangible assets acquired allocated to goodwill and other
intangible assets. These allocations are subject to change pending a final
determination and analysis of the total purchase prices and the fair value of
the assets acquired and liabilities assumed. The impact of such changes could be
material.

     The unaudited pro forma condensed combined information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have actually occurred if the
reorganizations, either individually or combined, had been consummated as of the
dates indicated, nor is it necessarily indicative of future operating results or
financial condition of the combined companies.

                                  RISK FACTORS

     The reorganizations involve a high degree of risk. By voting in favor of
the Healtheon-WebMD reorganization or the MEDE AMERICA reorganization, you will
be choosing to invest in Healtheon/ WebMD common stock. An investment in
Healtheon/WebMD common stock involves a high degree of risk. In addition to the
other information contained or incorporated by reference in this proxy
statement/ prospectus, you should carefully consider the following risk factors
in deciding whether to vote for the reorganizations.

GENERAL RISKS RELATING TO THE PROPOSED REORGANIZATIONS

HEALTHEON, WEBMD AND MEDE AMERICA HAVE INCURRED AND HEALTHEON/WEBMD WILL
CONTINUE TO INCUR SUBSTANTIAL LOSSES

     Healtheon began operations in January 1996 and has incurred net losses from
operations in each fiscal period since its inception. WebMD commercially
launched its Internet-based services in October 1998 and has incurred net losses
from operations since that time. MEDE AMERICA was formed in March 1995 and has
incurred net losses from operations in each fiscal period since its inception.
As of March 31, 1999, the three companies combined had accumulated losses of
$218 million. In addition, Healtheon/WebMD currently intends to invest heavily
in acquisitions, infrastructure development, applications development and sales
and marketing in order to extend its services to a growing number of potential
customers and partners.

     If the Healtheon-WebMD reorganization or the MEDE AMERICA reorganization
occurs, the purchase price of these acquisitions will be amortized over the
useful life of the tangible and intangible assets. We currently anticipate that
this amortization will cause Healtheon/WebMD to incur significant net losses for
the next several years. We expect that Healtheon/WebMD will incur increasing net
operating losses and negative cash flows for the foreseeable future and may
never be profitable.

THE BUSINESS OF PROVIDING SERVICES OVER THE INTERNET IS DIFFICULT TO EVALUATE
AND THE HEALTHEON/ WEBMD BUSINESS MODEL IS UNPROVEN

     Because each of Healtheon, WebMD and MEDE AMERICA recently began
operations, it is difficult to evaluate their businesses and prospects.
Healtheon/WebMD's revenue and income potential is unproven and its business
model is emerging. Healtheon/WebMD's pro forma historical financial information
is of limited value in projecting future operating results because of no
operating history as a combined organization and the emerging nature of its
markets. Healtheon/WebMD will initially derive a substantial portion of its
revenue from non-Internet network services, from development and consulting
services and from managing and operating its customers' information technology
infrastructures. Healtheon/WebMD may never achieve favorable operating results
or profitability.

HEALTHEON/WEBMD'S QUARTERLY OPERATING RESULTS MAY VARY

     Fluctuations in Healtheon/WebMD's quarterly results could affect the market
price of Healtheon/ WebMD's common stock in a manner unrelated to its long-term
operating performance. Healtheon/ WebMD expects that quarterly revenue and
operating results may fluctuate as a result of a number of factors, including:

     - changes in its strategic relationships;

     - future acquisitions and unexpected delays and costs with integrating
       these businesses;

     - entry into new healthcare markets;

     - new applications and services;

     - software defects, delays in development and other quality factors;

     - customer demand for Healtheon/WebMD's applications and services;
                                       28
<PAGE>   39

     - mix and variation of subscriber, advertising, sponsorship, consulting and
       transaction revenues;

     - our success in establishing and strengthening brand awareness;

     - the ability to meet project milestones or customer expectations;

     - the mix of consulting and transaction fee revenue;

     - variability in demand for Internet-based healthcare solutions;

     - changes within the healthcare industry; and

     - seasonality of demand.

     In addition, Healtheon/WebMD will be dependent on its distribution partners
and content and service providers, sponsors and advertisers, as well as the
above list. Healtheon/WebMD expects to increase activities and spending in
substantially all operational areas. Healtheon/WebMD will base its expense
levels in part upon its expectations concerning future revenue and these expense
levels will be relatively fixed in the short-term. If it has lower revenue,
Healtheon/WebMD may not be able to reduce its spending in the short-term in
response. Any shortfall in revenue would have a direct impact on Healtheon/
WebMD's results of operations. For these and other reasons, Healtheon/WebMD may
not meet the earnings estimates of securities analysts or investors and its
stock price could suffer.

HEALTHEON/WEBMD PRO FORMA ACCOUNTING FOR THE REORGANIZATIONS MAY CHANGE

     Healtheon/WebMD has allocated the total estimated purchase price for WebMD
and MEDE AMERICA on a preliminary basis to assets and liabilities based on
Healtheon/WebMD's best estimates of the fair value of these assets and
liabilities, with the excess costs over the net assets acquired allocated to
goodwill and other intangible assets. These allocations are subject to change
pending a final determination and analysis of the total purchase prices and the
fair value of the assets acquired and liabilities assumed. The impact of these
changes could be material to Healtheon/WebMD's future results of operations.

HEALTHEON/WEBMD WILL INCUR SIGNIFICANT EXPENSE TO ACQUIRE SUBSCRIBERS AND
PROMOTE OUR SERVICES

     Healtheon/WebMD intends to use a significant portion of the proceeds from
WebMD's sale of its capital stock to fund branding and advertising, including
promotional arrangements. Agreements and promotional arrangements with strategic
partners often require payments in various forms, including royalties, license
fees and other significant guaranteed amounts on a per subscriber or a minimum
dollar amount basis over terms ranging from one to three years. Some of these
payments must be made whether or not Healtheon/WebMD ever uses services under
these agreements. Healtheon/WebMD must also fund certain rebates and costs that
our strategic partners offer and incur in connection with the promotion of
WebMD. WebMD estimates that it will make the following aggregate guaranteed
payments under its current strategic agreements:

<S>                                                           <C>

2001........................................................   78.3 million
2002........................................................   40.4 million
2003........................................................   34.4 million
</TABLE>

     In addition, some strategic partner agreements and promotional arrangements
require payments that vary based on usage by subscribers. Healtheon/WebMD
anticipates additional arrangements with current and future strategic partners
that will require payments in various forms in amounts that may significantly
exceed the amounts required under the current arrangements. These guaranteed
payments, promotions and

                                       29
<PAGE>   40

other arrangements may require Healtheon/WebMD to incur significant expenses
with no guarantee of revenues.

     Promotional arrangements currently require, and future arrangements may
require, Healtheon/ WebMD to pay amounts that can be recouped only if
subscribers maintain a subscription and pay all required subscription fees for
an extended period of time. For example, for the year ended December 31, 1998,
WebMD accrued $5,000,000 in license fees payable to McKesson HBOC, Inc. for
software that McKessonHBOC intends to offer to healthcare professionals in
connection with its promotion of WebMD. WebMD is also obligated to pay
McKessonHBOC an annual $750,000 maintenance fee on this software beginning on
January 1, 2000. These subscriptions will be for 3 years, but will be subject to
cancellation after a year. If all of these subscriptions were canceled after one
year, WebMD would have paid $5,000,000 in license fees and would have only
received $3,000,000 in subscription fees. In addition, Healtheon/WebMD does not
know whether these subscribers will honor their contracts or pay any early
termination fee, if required. Accordingly, Healtheon/WebMD does not know whether
it will generate sufficient revenue from subscribers obtained through current or
future promotional arrangements to offset the cost of promotions.
Healtheon/WebMD also does not know whether subscribers obtained through any
promotional arrangements will actually use its services. Therefore, the number
of paying subscribers may not be indicative of the level of usage of our
services, and the level of usage is likely to be a primary factor in determining
the amount of advertising, sponsorship and transaction revenues.

HEALTHEON/WEBMD MAY BE UNABLE TO GENERATE SIGNIFICANT ADVERTISING REVENUES

     Healtheon/WebMD will derive a portion of its revenues from advertising on
the WebMD Web site. Significant advertising revenues have not been earned by
WebMD, and Healtheon/WebMD may not be able to generate significant advertising
revenues. No standards have been widely accepted to measure the effectiveness of
Web advertising. If no standards develop, existing advertisers may not continue
their current level of Web advertising, and advertisers that have traditionally
relied on other advertising media may be reluctant to advertise on the Web.
Advertisers that already have invested substantial resources in other
advertising methods may be reluctant to adopt a new strategy. Healtheon/WebMD's
business would be adversely affected if the market for Web advertising fails to
develop or develops more slowly than expected.

     Different pricing models are used to sell advertising on the Web. It is
difficult to predict which, if any, will emerge as the industry standard. This
makes it difficult to project future advertising revenues. Moreover, "filter"
software programs that limit or prevent advertising from being delivered to a
Web user's computer are available. Widespread adoption of this software could
adversely affect the commercial viability of Web advertising.

THE HEALTHCARE INDUSTRY MAY NOT ACCEPT HEALTHEON/WEBMD'S SOLUTIONS

     To be successful, Healtheon/WebMD must attract a significant number of
customers throughout the healthcare industry. To date, the healthcare industry
has been resistant to adopting new information technology solutions. Electronic
information exchange and transaction processing by the healthcare industry is
still developing. Healtheon/WebMD believes that complexities in the nature of
the healthcare transactions that must be processed have hindered the development
and acceptance of information technology solutions by the industry. Conversion
from traditional methods to electronic information exchange may not occur as
rapidly as Healtheon/WebMD expects it will. Even if the conversion does occur as
rapidly as expected, healthcare industry participants may use applications and
services offered by others.

     Healtheon/WebMD believes that it must gain significant market share with
its applications and services before its competitors introduce alternative
products, applications or services with features similar to its current or
proposed offerings. Healtheon/WebMD's business plan is based on its belief that
the value and market appeal of its solution will grow as the number of
participants and the scope of the transaction services available on its platform
increase. Healtheon/WebMD may not achieve the critical mass of users

                                       30
<PAGE>   41

it believes is necessary to become successful. In addition, Healtheon/WebMD
expects to generate a significant portion of its revenue from subscription and
transaction-based fees. Consequently, any significant shortfall in the number of
users or transactions occurring over its platform would adversely affect
Healtheon/WebMD's financial results.

HEALTHEON/WEBMD WILL RELY ON STRATEGIC RELATIONSHIPS TO GENERATE REVENUE

     To be successful, Healtheon/WebMD must establish and maintain strategic
relationships with leaders in a number of healthcare industry segments. This is
critical to Healtheon/WebMD's success because Healtheon/WebMD believes that
these relationships will enable it to:

     - extend the reach of its applications and services to the various
       participants in the healthcare industry;

     - obtain specialized healthcare expertise;

     - develop and deploy new applications;

     - further enhance the Healtheon/WebMD brand; and

     - generate revenue.

     Entering into strategic relationships is complicated because some of
Healtheon's, WebMD's and MEDE AMERICA's current and future strategic partners
may decide to compete with Healtheon/ WebMD and some strategic relationships may
put Healtheon/WebMD in competition with existing business partners or customers.
In addition, Healtheon/WebMD may not be able to establish relationships with key
participants in the healthcare industry if Healtheon, WebMD or MEDE AMERICA has
established relationships with competitors of these key participants.
Consequently, it is important that Healtheon/WebMD is perceived as independent
of any particular customer or partner. Moreover, many potential partners may
resist working with Healtheon/WebMD until its applications and services have
been successfully introduced and have achieved market acceptance.

     As Healtheon/WebMD establishes strategic relationships, it will depend on
its partners' ability to generate increased acceptance and use of its platform,
applications and services. To date, Healtheon, WebMD and MEDE AMERICA have
established only a limited number of strategic relationships and these
relationships are in the early stages of development. These companies have
limited experience in establishing and maintaining strategic relationships with
healthcare industry participants. If Healtheon/WebMD loses any of these
strategic relationships, fails to obtain modifications of existing relationships
or fails to establish additional relationships, or if Healtheon's strategic
partners fail to actively pursue additional business relationships and
partnerships, Healtheon/WebMD would not be able to execute its business plan and
its business would suffer significantly.

     On February 9, 1999, SmithKline Beecham announced that it has agreed to
sell SmithKline Beecham Clinical Laboratories, Inc., or SmithKline Labs, to
Quest Diagnostics, Incorporated. SmithKline Labs has been one of
Healtheon/WebMD's strategic partners since December 1997, and its relationship
with them has been beneficial. Healtheon's agreements with SmithKline Labs will
remain in effect as a result of the acquisition. However, Healtheon/WebMD will
need to work with a new business partner, which involves new risks including
different customer requirements and working relationships. In addition,
Healtheon/ WebMD's ability to take advantage of its relationship with SmithKline
Labs may be impaired because the attention of management of the combining
companies may be diverted during and after SmithKline Labs' acquisition.
Healtheon/WebMD may not experience increased use of its platform, applications
and services even if it establishes and maintains these strategic relationships.

     In addition, Healtheon/WebMD will depend on its strategic distribution
relationships to grow the WebMD subscriber base. Exclusive rights that WebMD has
granted to market its services in the infertility, obstetrics, gynecology,
cardiology, orthopaedics, cardiothoracic, integrated delivery networks and
medical supply markets, and its agreement not to market through some competitors
of its strategic partners, may limit Healtheon/WebMD's ability to fully
penetrate these markets.

THE REORGANIZATIONS COULD HARM KEY THIRD PARTY RELATIONSHIPS

     The present and potential relationship of Healtheon, WebMD and MEDE AMERICA
with sponsors, content providers, advertisers, users and subscribers may be
harmed by the proposed reorganizations. Uncertainties regarding sponsorship,
joint venture overlap and new service development following the mergers may
cause these parties to delay decisions regarding these relationships. Any
changes in these relationships could harm Healtheon/WebMD's business.

HEALTHEON, WEBMD AND MEDE AMERICA MAY LOSE CONTRACTUAL RIGHTS DUE TO THE
REORGANIZATIONS

     Healtheon, WebMD and MEDE AMERICA have contracts with many suppliers,
customers and other business partners. Some of these contracts require
Healtheon, WebMD and MEDE AMERICA to obtain the consent, waiver or approval of
these other parties in connection with the proposed reorganizations. If consent,
waiver or approval cannot be obtained, Healtheon/WebMD may lose the right to use
intellectual property or other rights that are necessary for smooth operation.
Healtheon, WebMD and MEDE AMERICA have agreed to seek to secure the necessary
consents, waivers and approvals. However, Healtheon, WebMD and MEDE AMERICA may
not be able to obtain all of the necessary consents, waivers and approvals.
Failure to do so could harm Healtheon/WebMD's business.

     In addition, each of Healtheon, WebMD and MEDE AMERICA have granted
exclusive rights to third parties with regard to certain content, sponsorship or
other strategic relationships. Some of these rights conflict with rights granted
by the other party. We may not successfully resolve these conflicts and failure
to do so could harm Healtheon/WebMD's business.

OFFICERS AND DIRECTORS OF BOTH COMPANIES HAVE DIFFERENT INTERESTS FROM YOURS

     The directors and officers of Healtheon, WebMD and MEDE AMERICA have
certain interests in the reorganizations and participate in arrangements that
are different from, or are in addition to, those of Healtheon, WebMD and MEDE
AMERICA stockholders generally. These include:

     - Board of Directors. Messrs. Long, Arnold,                ,
                      ,                ,                ,                ,
                      , and                will serve on the Board of
       Healtheon/WebMD. Messrs. Long,                ,                and
                      serve on Healtheon's board and Mr. Arnold,
                      ,                and                serve on WebMD's
       board.

     - Executive Officers. Mr. Long will serve as Chairman and Chief Operating
       Officer and Mr. Arnold will serve as Chief Executive Officer of
       Healtheon/WebMD. If Mr. Arnold is terminated by Healtheon/WebMD other
       than for cause or if he resigns after a diminution in his authority,
       options owned by him to acquire 923,067 shares of Healtheon/WebMD, which
       are currently subject to vesting conditions, will vest.

     - Microsoft. Microsoft will have the right to require Healtheon/WebMD to
       register for resale the Healtheon/WebMD common stock owned by Microsoft.
       Microsoft and Healtheon/WebMD have also agreed to expand Microsoft's
       strategic relationship with WebMD following the reorganizations to
       encompass the entire company.

     - Premiere Technologies. Premiere Technologies, Inc. and WebMD entered into
       an amendment to their co-marketing and integration agreement in
       connection with obtaining Premiere's agreement to vote for the
       Healtheon-WebMD reorganization agreement and the WebMD merger. The
       amendment requires WebMD to use its best efforts to cause Healtheon/WebMD
       to honor the rights and obligations under that agreement, including the
       exclusivity for telecommunications services. Boland T. Jones is the
       President and Chief Executive Officer of Premiere and a WebMD board
       member. William P. Payne is Vice Chairman of Premiere and Chairman of one
       of its subsidiaries. Mr. Payne is also the Vice Chairman of WebMD.

                                       32
<PAGE>   43

     - Registration Rights. Welsh, Carson, Anderson & Stowe and William Blair &
       Co., L.L.C., two large stockholders of MEDE AMERICA, will have the right
       to require Healtheon/WebMD to register for resale up to 6,000,000 of the
       shares of Healtheon/WebMD common stock that they receive as a result of
       the merger. Thomas E. McInerney and Anthony J. de Nicola, directors of
       MEDE AMERICA, are general partners of WCAS. Timothy M. Murray, a director
       of MEDE AMERICA, is a principal of William Blair & Co.

     - Stock Options. Employees of MEDE AMERICA will receive options to purchase
       an aggregate of 700,000 shares of Healtheon/WebMD common stock, with an
       exercise price of $45.72 per share, following the completion of the
       mergers, to be allocated individually at a later date. The options will
       vest over four years, and are intended to serve as compensation for
       continued service to the combined company. Based upon the fair value of
       Healtheon/WebMD's common stock at the date of grant, these options may
       generate additional compensation costs to Healtheon/WebMD over the
       vesting period of the awards.

HEALTHEON/WEBMD'S BUSINESS WILL SUFFER IF IT DOES NOT EXPAND ITS SUITE OF
APPLICATIONS

     Healtheon/WebMD's business will suffer if it does not expand the breadth of
its applications quickly. Healtheon currently offers a limited number of
applications on its platform and many of WebMD's service offerings are not fully
developed. For example, WebMD does not currently provide a site-wide search
capability on its Web site, and its electronic data interchange services do not
include claims processing. Healtheon/WebMD's future success depends on quickly
introducing new applications and services in several healthcare segments. Most
of WebMD's subscribers were acquired through promotional arrangements which do
not require the subscribers to use or pay for their WebMD subscriptions. If
Healtheon/WebMD cannot improve the functionality of the suite of WebMD Internet
applications, it will not be able to sustain or increase subscriber or
advertising revenue. Healtheon/WebMD will not have the internal resources and
specialized healthcare expertise to develop all these applications and services
independently. Consequently, it must rely on a combination of internal
development, strategic relationships, licensing and acquisitions to develop
these applications and services. Each of Healtheon/WebMD's applications,
regardless of how it was developed, must be integrated and customized to operate
with existing customer legacy computer systems and Healtheon/WebMD's platform.
Developing, integrating and customizing these applications and services will be
expensive and time consuming. Even if Healtheon/ WebMD is successful, these
applications and services may never achieve market acceptance, which could also
cause Healtheon/WebMD's business to suffer.

HEALTHEON/WEBMD MUST ACQUIRE TECHNOLOGIES AND COMPANIES TO INCREASE ITS CUSTOMER
BASE

     Healtheon/WebMD expects to continue to acquire technologies and other
healthcare technology companies to increase the number and variety of
applications and services on its platform and to increase its customer base. In
May 1998 Healtheon acquired ActaMed Corporation, and in August 1998 acquired
substantially all the assets of Metis, LLC. In January 1999, WebMD acquired
Sapient Health Network, Inc. and Direct Medical Knowledge, Inc. To be
successful, Healtheon/WebMD will need to identify additional applications,
technologies and businesses that are complementary to its own, integrate
disparate technologies and corporate cultures and manage a geographically
dispersed company. Future acquisitions could divert management's attention from
other business concerns and expose it to unforeseen liabilities or risks
associated with entering new markets. Finally, Healtheon/WebMD may lose key
employees while integrating these new companies.

     Integrating newly acquired organizations and technologies into
Healtheon/WebMD could be expensive, time consuming and may strain its resources.
In addition, Healtheon/WebMD may lose its current customers if any acquired
companies have relationships with competitors of Healtheon/WebMD's customers.
Consequently, Healtheon/WebMD may not be successful in integrating acquired
businesses or technologies and may not achieve anticipated revenue and cost
benefits. Healtheon/WebMD also cannot guarantee that these acquisitions will
result in sufficient revenues or earnings to justify its investment in, or
expenses related to, these acquisitions or that any synergies will develop. The
healthcare industry is
                                       33
<PAGE>   44

consolidating and Healtheon/WebMD expects that it will face intensified
competition for acquisitions, especially from larger, better-funded
organizations. If Healtheon/WebMD fails to execute its acquisition strategy
successfully for any reason, its business will suffer significantly.

     Healtheon/WebMD intends to pay for some of its acquisitions by issuing
additional common stock and this would dilute its stockholders. Healtheon/WebMD
may also use cash to buy companies or technologies, and it may need to incur
debt to pay for these acquisitions. Acquisition financing may not be available
on favorable terms or at all. In addition, Healtheon/WebMD may be required to
amortize significant amounts of goodwill and other intangible assets in
connection with future acquisitions, which would materially increase its
operating expenses.

HEALTHEON/WEBMD WILL FACE TECHNICAL, OPERATIONAL AND STRATEGIC CHALLENGES THAT
MAY PREVENT IT FROM SUCCESSFULLY INTEGRATING HEALTHEON, WEBMD AND MEDE AMERICA

     The reorganizations involve risks related to the integration and management
of acquired technology, operations and personnel. The integration of Healtheon,
WebMD and MEDE AMERICA will be a complex, time consuming and expensive process
and may disrupt Healtheon/WebMD's business if not completed in a timely and
efficient manner. Following the reorganizations, Healtheon/WebMD must operate as
a combined organization utilizing common information and communication systems,
operating procedures, financial controls and human resources practices.
Healtheon/WebMD may encounter substantial difficulties, costs and delays
involved in integrating the operations of Healtheon, WebMD and MEDE AMERICA,
including:

     - potential incompatibility of business cultures

     - perceived adverse changes in business focus

     - potential conflicts in sponsor, advertising or content relationships

     - the loss of key employees and diversion of the attention of management
       from other ongoing business concerns.

HEALTHEON/WEBMD MUST MANAGE ITS GROWTH

     Healtheon, WebMD and MEDE AMERICA have rapidly and significantly expanded
their operations and expect to continue to do so. This growth has placed a
significant strain on each company's managerial, operational, financial and
other resources and is expected to continue to strain the resources of
Healtheon/ WebMD. We expect that this growth will continue and that
Healtheon/WebMD will hire a significant number of new employees to support its
business.

     Healtheon's, WebMD's and MEDE AMERICA's current information systems,
procedures and controls may not continue to support Healtheon/WebMD's
operations, and may hinder its ability to exploit the market for healthcare
applications and services. Healtheon/WebMD is in the process of evaluating its
accounting and management information systems and anticipates that it may
implement new systems within the next twelve months. Healtheon/WebMD could
experience interruptions to its business while it transitions to new systems.
Healtheon/WebMD cannot guarantee that its systems, procedures and controls will
be adequate to support expansion of our operations.

     Healtheon/WebMD future operating results will substantially depend on the
ability of its officers and key employees to manage changing business conditions
and to implement and improve its technical, administrative, financial control
and reporting systems. If Healtheon/WebMD is unable to respond to and manage
changing business conditions, then the quality of its services and its results
of operations could be materially adversely affected.

                                       34
<PAGE>   45

HEALTHEON/WEBMD'S BUSINESS WILL SUFFER IF COMMERCIAL USERS AND SUBSCRIBERS DO
NOT ACCEPT INTERNET SOLUTIONS

     Healtheon/WebMD's business model depends on the adoption of Internet
solutions by commercial users and the subscribers. Healtheon/WebMD's business
could suffer dramatically if Internet solutions are not accepted or not
perceived to be effective. The Internet may not prove to be a viable commercial
marketplace for a number of reasons, including:

     - inadequate development of the necessary infrastructure for communication
       speed, access and server reliability;

     - security and confidentiality concerns;

     - lack of development of complementary products, such as high-speed modems
       and high-speed communication lines;

     - implementation of competing technologies;

     - delays in the development or adoption of new standards and protocols
       required to handle increased levels of Internet activity; and

     - governmental regulation.

     Healtheon/WebMD expects Internet use to grow in number of users and volume
of traffic. The Internet infrastructure may be unable to support the demands
placed on it by this continued growth. Growth in the demand for
Healtheon/WebMD's applications and services depends on the adoption of Internet
solutions by healthcare participants, which requires the acceptance of a new way
of conducting business and exchanging information. The healthcare industry, in
particular, relies on legacy systems that may be unable to benefit from
Healtheon/WebMD's Internet-based platform. To maximize the benefits of
Healtheon/WebMD's platform, healthcare participants must be willing to allow
sensitive information to be stored in Healtheon/WebMD's databases.
Healtheon/WebMD can process transactions for healthcare participants that
maintain information on their own proprietary databases. However, the benefits
of Healtheon/WebMD's connectivity and sophisticated information management
solution are limited under these circumstances. Customers using legacy and
client-server systems may refuse to adopt new systems when they have made
extensive investment in hardware, software and training for older systems.

PERFORMANCE OR SECURITY PROBLEMS WITH HEALTHEON/WEBMD'S SYSTEMS COULD DAMAGE ITS
BUSINESS

     Healtheon/WebMD's customer satisfaction and its business could be harmed if
Healtheon/WebMD or its customers experience system delays, failures or loss of
data. Healtheon, WebMD and MEDE AMERICA currently process substantially all
their customer transactions and data at their respective facilities. Although
Healtheon and WebMD have safeguards for emergencies, they do not have backup
facilities to process information if these facilities are not functioning. The
occurrence of a major catastrophic event or other system failure at any of
Healtheon/WebMD's facilities could interrupt data processing or result in the
loss of stored data. In addition, Healtheon/WebMD will depend on the efficient
operation of Internet connections from customers to our systems. These
connections, in turn, depend on the efficient operation of Web browsers,
Internet service providers and Internet backbone service providers, all of which
have had periodic operational problems or experienced outages.

     A material security breach could damage Healtheon/WebMD's reputation or
result in liability. Healtheon/WebMD will retain confidential customer and
patient information in its processing centers. Healtheon/WebMD may be required
to spend significant capital and other resources to protect against security
breaches or to alleviate problems caused by breaches. Any well-publicized
compromise of Internet security could deter people from using the Internet or
from conducting transactions that involve transmitting confidential information,
including confidential healthcare information. Therefore, it is critical that
these facilities and infrastructure remain secure and are perceived by the
marketplace to be secure.

                                       35
<PAGE>   46

Despite the implementation of security measures, this infrastructure may be
vulnerable to physical break-ins, computer viruses, programming errors, attacks
by third parties or similar disruptive problems.

TECHNOLOGY MAY CHANGE FASTER THAN HEALTHEON/WEBMD CAN UPDATE ITS APPLICATIONS
AND SERVICES

     Healthcare information exchange and transaction processing is a relatively
new and evolving market. The pace of change in Healtheon/WebMD's markets is
rapid and there are frequent new product introductions and evolving industry
standards. Healtheon/WebMD may be unsuccessful in responding to technological
developments and changing customer needs. In addition, Healtheon/WebMD's
applications and services offerings may become obsolete due to the adoption of
new technologies or standards.

HEALTHEON/WEBMD'S PLATFORM INFRASTRUCTURE AND SCALABILITY ARE NOT PROVEN

     So far, Healtheon and WebMD have processed a limited number and variety of
transactions over their platforms. Similarly, a limited number of healthcare
participants use these platforms. Healtheon/ WebMD's systems may not accommodate
increased use while maintaining acceptable overall performance. MEDE AMERICA, by
contrast, currently processes approximately 950,000 transactions per business
day. Healtheon/WebMD must continue to expand and adapt its network
infrastructure to accommodate additional users, increased transaction volumes
and changing customer requirements. This expansion and adaptation will be
expensive and will divert Healtheon/WebMD's attention from other activities.

     Healtheon/WebMD's service agreements will contain performance standards. If
Healtheon/WebMD fails to meet these standards, its customers could terminate
their agreements with Healtheon/WebMD. The loss of any of Healtheon/WebMD's
service agreements would directly and significantly impact its business.
Healtheon/WebMD may be unable to expand or adapt its network infrastructure to
meet additional demand or its customers' changing needs on a timely basis and at
a commercially reasonable cost, or at all.

     Healtheon/WebMD will depend on service and content providers to provide
information and data feeds on a timely basis. Healtheon/WebMD's Web sites could
experience disruptions or interruptions in service due to the failure or delay
in the transmission or receipt of this information. In addition,
Healtheon/WebMD's subscribers and consumers will depend on Internet service
providers, online service providers and other Web site operators for access to
our Web sites. All of them have experienced significant outages in the past and
could experience outages, delays and other difficulties in the future due to
system failures unrelated to our systems. Any significant interruptions in our
services or increases in response time could result in a loss of potential or
existing subscribers, consumers, strategic partners, advertisers or sponsors
and, if sustained or repeated, could reduce the attractiveness of Healtheon/
WebMD's services.

HEALTHEON/WEBMD'S REVENUES WILL BE CONCENTRATED IN A FEW CUSTOMERS

     Healtheon/WebMD expects that it will generate a significant portion of its
revenue from a small number of customers for the next few years. If
Healtheon/WebMD does not generate as much revenue from these customers as it
expects, or if it loses any of these customers, Healtheon/WebMD's revenue will
be significantly reduced which would harm its business. Currently, Healtheon
receives a substantial majority of its revenue from four customers. United
Health Group, SmithKline Labs, Brown & Toland and Beech Street together
accounted for approximately 86% of Healtheon's total revenue for the three
months ended March 31, 1999. On a pro forma basis after giving effect to the
reorganizations with WebMD and MEDE AMERICA, these four customers would account
for 43% of Healtheon/WebMD's total pro forma revenue for the three months ended
March 31, 1999. Customers who also own shares of Healtheon stock, including
UnitedHealth Group and SmithKline Labs, accounted for 43% of Healtheon's total
revenue in 1998 and 55% of Healtheon's total revenue in 1997. Upon the
completion of the reorganizations, UnitedHealth Group will own approximately
6.3% of Healtheon/WebMD's stock and SmithKline Labs will own approximately 4.4%
of Healtheon/WebMD's stock.

                                       36
<PAGE>   47

HEALTHEON/WEBMD WILL FACE SIGNIFICANT COMPETITION

     The market for healthcare information services is intensely competitive,
rapidly evolving and subject to rapid technological change. Many of
Healtheon/WebMD's competitors have greater financial, technical, product
development, marketing and other resources than Healtheon/WebMD will have. These
organizations may be better known and have more customers than Healtheon/WebMD
will have. Healtheon/WebMD may be unable to compete successfully against these
organizations.

     Many of Healtheon/WebMD's competitors have announced or introduced Internet
strategies that will compete with Healtheon/WebMD's applications and services.
Healtheon/WebMD has many competitors, including:

     - healthcare information software vendors, including McKesson HBOC and
       Shared Medical Systems Corporation;

     - healthcare electronic data interchange companies, including ENVOY
       Corporation and National Data Corporation;

     - large information technology consulting service providers, including
       Andersen Consulting, International Business Machines Corporation and
       Electronic Data Systems Corporation; and

     - small regional organizations.

     Healtheon/WebMD expects that major software information systems companies
and others specializing in the healthcare industry will offer competitive
applications or services. Some of Healtheon/ WebMD's large customers may also
compete with Healtheon/WebMD.

     Healtheon/WebMD will also compete for subscribers, consumers, content and
service providers, advertisers, sponsors and acquisition candidates with the
following categories of companies:

     - online services or Web sites targeted to the healthcare industry and
       healthcare consumers generally, including medscape.com, pol.net,
       ivillage.com, medcareonline.com, mediconsult.com, betterhealth.com,
       drkoop.com, onhealth.com, healthcentral.com and thriveonline.com;

     - publishers and distributors of traditional offline media, including those
       targeted to healthcare professionals, many of which have established or
       may establish Web sites;

     - general purpose consumer online services and portals which provide access
       to healthcare-related content and services;

     - public sector and non-profit Web sites that provide healthcare
       information without advertising or commercial sponsorships;

     - vendors of healthcare information, products and services distributed
       through other means, including direct sales, mail and fax messaging; and

     - Web search and retrieval services and other high-traffic Web sites.

CHANGES IN THE HEALTHCARE INDUSTRY COULD ADVERSELY AFFECT HEALTHEON/WEBMD'S
BUSINESS

     The healthcare industry is highly regulated and is subject to changing
political, economic and regulatory influences. These factors affect the
purchasing practices and operation of healthcare organizations. Changes in
current healthcare financing and reimbursement systems could cause Healtheon/
WebMD to make unplanned modifications of applications or services, or result in
delays or cancellations of orders or in the revocation of endorsement of
Healtheon/WebMD's applications and services by healthcare participants. Federal
and state legislatures have periodically considered programs to reform or amend
the U.S. healthcare system at both the federal and state level. These programs
may contain proposals to increase governmental involvement in healthcare, lower
reimbursement rates or otherwise change the environment in which healthcare
industry participants operate. Healthcare industry participants may respond by
reducing their investments or postponing investment decisions, including
investments in

                                       37
<PAGE>   48

Healtheon/WebMD's applications and services. Healtheon/WebMD does not know what
effect any proposals would have on its business.

     Many healthcare providers are consolidating to create integrated healthcare
delivery systems with greater market power. These providers may try to use their
market power to negotiate price reductions for Healtheon/WebMD's applications
and services. If Healtheon/WebMD is forced to reduce its prices, its operating
margins would decrease. As the healthcare industry consolidates, competition for
customers will become more intense and the importance of acquiring each customer
will become greater.

GOVERNMENT REGULATION COULD ADVERSELY AFFECT HEALTHEON/WEBMD'S BUSINESS

     Healtheon/WebMD's business will be subject to government regulation.
Existing as well as new laws and regulations could adversely affect its
business. Laws and regulations may be adopted with respect to the Internet or
other on-line services covering issues such as:

     - user privacy;

     - pricing;

     - content;

     - copyrights;

     - distribution; and

     - characteristics and quality of products and services.

     Moreover, the applicability to the Internet of existing laws in various
jurisdictions governing issues such as property ownership, sales and other
taxes, libel and personal privacy is uncertain and may take years to resolve.
Demand for Healtheon/WebMD's applications and services may be affected by
additional regulation of the Internet. For example, until recently Health Care
Financing Administration guidelines prohibited transmission of Medicare
eligibility information over the Internet.

     Healtheon/WebMD will be subject to extensive regulation relating to the
confidentiality and release of patient records and other health care industry
issues. For example, legislation currently prevents MEDE AMERICA from providing
Medicare claims processing services and eligibility verification from the same
database. Additional legislation governing the distribution of medical records
has been proposed at both the state and federal level. It may be expensive to
implement security or other measures designed to comply with any new
legislation. Moreover, Healtheon/WebMD may be restricted or prevented from
delivering patient records electronically.

     Legislation currently being considered at the federal level could affect
Healtheon/WebMD's business. For example, the Health Insurance Portability and
Accountability Act of 1996 mandates the use of standard transactions, standard
identifiers, security and other provisions by the year 2000. Healtheon/ WebMD
will design its platform and applications to comply with these proposed
regulations; however, until these regulations become final, they could change,
which could cause Healtheon/WebMD to use additional resources to revise its
platform and applications and lead to delays. In addition, Healtheon/ WebMD's
success depends on other healthcare participants complying with these
regulations.

     Some computer applications and software are considered medical devices and
are subject to regulation by the United States Food and Drug Administration, or
the FDA. None of Healtheon, WebMD or MEDE AMERICA believes that its current
applications or services are subject to FDA regulation. Healtheon/ WebMD may
expand its application and service offerings into areas that subject it to FDA
regulation. Healtheon/WebMD has no experience in complying with FDA regulations.
Healtheon/WebMD believes that complying with FDA regulations would be time
consuming, burdensome and expensive and could delay its introduction of new
applications or services.

                                       38
<PAGE>   49

HEALTHEON/WEBMD MAY FACE PRODUCT-RELATED LIABILITIES

     Although Healtheon/WebMD and its customers will test its applications, they
may contain defects or result in system failures. In addition, Healtheon/WebMD's
platform and Web sites may experience problems in security, availability,
scalability or other critical features. These defects or problems could result
in the loss of or delay in generating revenue, loss of market share, failure to
achieve market acceptance, diversion of development resources, injury to
Healtheon/WebMD's reputation or increased insurance costs.

     Many of Healtheon/WebMD's strategic relationships and services agreements
involve providing critical information technology services to Healtheon/WebMD's
clients' businesses. If Healtheon/WebMD fails to meet its clients' expectations,
its reputation could suffer and it could be liable for damages. In addition,
patient care could suffer and Healtheon/WebMD could be liable if its systems
fail to deliver correct information in a timely manner. Healtheon/WebMD's
insurance may not protect it from this risk. Finally, if third persons were able
to penetrate our network security or otherwise misappropriate our users'
personal information our reputation could be damaged and we could be subject to
liability.

     Many of Healtheon/WebMD's contracts will limit its liability arising from
its errors; however, these provisions may not be enforceable and may not protect
it from liability. While Healtheon/WebMD has general liability insurance that it
believes is adequate, including coverage for errors and omissions,
Healtheon/WebMD may not be able to maintain this insurance on reasonable terms
in the future. In addition, Healtheon/WebMD's insurance may not be sufficient to
cover large claims and Healtheon/ WebMD's insurer could deny coverage on claims.
If Healtheon/WebMD is liable for an uninsured or underinsured claim or if
Healtheon/WebMD's premiums increase significantly, its financial condition could
be materially harmed.

     In addition, Healtheon/WebMD could be subject to third party claims based
on the nature and content of information supplied on its Web sites by
Healtheon/WebMD or third parties, including content providers, medical advisors
or users. Healtheon/WebMD could also be subject to liability for content that
may be accessible through its Web sites or third party Web sites linked from its
Web sites or through content and information that may be posted by users in chat
rooms or bulletin boards. Even if these claims do not result in liability to
Healtheon/WebMD, investigating and defending against these claims could be
expensive and time-consuming and could divert management's attention away from
operating the business.

HEALTHEON/WEBMD'S INTELLECTUAL PROPERTY MAY BE SUBJECTED TO INFRINGEMENT CLAIMS
OR MAY BE INFRINGED UPON

     Healtheon/WebMD's intellectual property will be important to its business.
Healtheon/WebMD could be subject to intellectual property infringement claims as
the number of its competitors grows and the functionality of its applications
overlaps with competitive offerings. These claims, even if not meritorious,
could be expensive and divert management's attention from operating the company.
If Healtheon/WebMD becomes liable to third parties for infringing their
intellectual property rights, it could be required to pay a substantial damage
award and to develop noninfringing technology, obtain a license or cease selling
the applications that contain the infringing intellectual property.
Healtheon/WebMD may be unable to develop noninfringing technology or obtain a
license on commercially reasonable terms, or at all. In addition,
Healtheon/WebMD may not be able to protect against misappropriation of its
intellectual property. Third parties may infringe upon Healtheon/WebMD's
intellectual property rights, Healtheon/ WebMD may not detect this unauthorized
use and it may be unable to enforce its rights.

LENGTHY SALES AND IMPLEMENTATION CYCLES FOR HEALTHEON/WEBMD'S SOLUTIONS COULD
ADVERSELY AFFECT ITS REVENUE GROWTH

     A key element of Healtheon/WebMD's strategy is to market its solutions
directly to large healthcare organizations. Healtheon/WebMD will be unable to
control many of the factors that will influence its customers' buying decisions.
Healtheon/WebMD expects that the sales and implementation process will be
lengthy and will involve a significant technical evaluation and commitment of
capital and other resources
                                       39
<PAGE>   50

by its customers. The sale and implementation of its solutions are subject to
delays due to its customers' internal budgets and procedures for approving large
capital expenditures and deploying new technologies within their networks.

     Healtheon/WebMD will need to expend substantial resources to integrate its
applications with the existing legacy and client-server architectures of large
healthcare organizations. Healtheon/WebMD has limited experience in integrating
its applications with large, complex architectures, and it may experience delays
in the integration process. These delays would, in turn, delay its ability to
generate revenue from these applications and could adversely affect its results
of operations.

HEALTHEON/WEBMD'S BUSINESS WILL BE ADVERSELY AFFECTED IF IT CANNOT ATTRACT AND
RETAIN KEY PERSONNEL

     Healtheon/WebMD's success will depend significantly on its senior
management team and other key employees. Healtheon/WebMD needs to attract,
integrate, motivate and retain additional highly skilled technical people. In
particular, Healtheon/WebMD needs to attract experienced professionals capable
of developing, selling and installing complex healthcare information systems.
Healtheon/WebMD faces intense competition for these people. If the
Healtheon/WebMD reorganization occurs, Healtheon/ WebMD's executive management
team, including Jeffrey T. Arnold, the designated Chief Executive Officer of
Healtheon/WebMD, and W. Michael Long, its designated Chairman and Chief
Operating Officer, will be critical to Healtheon/WebMD's success.

IF HEALTHEON/WEBMD IS UNABLE TO MAINTAIN ITS RELATIONSHIPS WITH CONTENT
PROVIDERS, ITS BUSINESS COULD BE ADVERSELY AFFECTED

     WebMD relies on independent content providers for the majority of the
clinical, educational and other general healthcare information that it provides
through its web site. WebMD has entered into strategic relationships with
several companies to obtain content for WebMD, and Healtheon/WebMD intends to
enter into additional relationships in the future. Healtheon/WebMD's success
depends significantly on its ability to maintain WebMD's existing relationships
with these content providers and to build new relationships with other content
providers. WebMD's agreements with content providers are short-term and
non-exclusive. Termination of one or more significant content provider
agreements would decrease the selection of healthcare-related news and
information which can be offered to subscribers and consumers. Healtheon/WebMD's
competitors could offer content that is similar or the same as that provided on
the WebMD web site. If this information is readily available elsewhere,
including on other web sites at a reduced cost or free of charge,
Healtheon/WebMD may lose subscribers. In addition, WebMD depends on content
providers to deliver high quality content from reliable sources and to
continually upgrade their content in response to subscriber and consumer demand
and evolving healthcare industry trends. Any failure by these parties to develop
and maintain high quality, attractive content could result in subscriber and
consumer dissatisfaction, could inhibit Healtheon/WebMD's ability to add
subscribers and consumers and could dilute the WebMD brand name.

SOME OF WEBMD'S SERIES A PREFERRED STOCK AND SERIES B PREFERRED STOCK MAY REMAIN
OUTSTANDING FOLLOWING THE WEBMD MERGER

     If the holders of the WebMD Series A preferred stock and Series B preferred
stock do not convert their shares into WebMD common stock prior to the WebMD
merger, these shares of preferred stock will remain outstanding as shares of
WebMD. If this were to occur, WebMD would have minority stockholders who could
hold up to approximately 12.6% of the capital stock of WebMD. The rights of
these minority stockholders may delay or limit action that Healtheon/WebMD might
otherwise want to take with respect to WebMD. In addition, complying with these
rights might be costly to Healtheon/WebMD and divert the time and efforts of its
managers.

     Healtheon, WebMD and McKessonHBOC have been discussing the modification of
the existing strategic relationship between WebMD and McKessonHBOC as well as
McKessonHBOC's rights to

                                       40
<PAGE>   51

purchase additional equity in WebMD and whether McKessonHBOC will convert its
Series A and Series B preferred stock into common stock of WebMD and thus
receive Healtheon-WebMD common stock in the reorganization.

YOU SHOULD NOT RELY ON REPORTS IN THE PRESS REGARDING OUR BUSINESS BECAUSE THEY
MAY BE INACCURATE

     Healtheon, WebMD and MEDE AMERICA have received, and may continue to
receive, a high degree of media coverage. Some of this media coverage has
included, and future media coverage may include, inaccurate or incomplete
information and forward-looking statements that involve numerous risks and
uncertainties.

YOU MAY NOT KNOW THE NUMBER OF SHARES OF HEALTHEON/WEBMD COMMON STOCK TO BE
ISSUED TO MEDE AMERICA STOCKHOLDERS UNTIL AS LATE AS TWO DAYS PRIOR TO THE MEDE
AMERICA STOCKHOLDERS' MEETING

     Upon the completion of the MEDE AMERICA reorganization, stockholders of
MEDE AMERICA will be entitled to receive 0.6593 of a share of Healtheon/WebMD
common stock per MEDE AMERICA share, subject to adjustment based on changes in
the market price of Healtheon's common stock prior to the stockholders' meeting.
If the lower of the ten day average closing price of Healtheon's common stock
price for the period ending July 30, 1999 and the period ending two days before
the stockholders' meeting is greater than $63.70 or less than $38.68, then the
actual number of shares MEDE AMERICA stockholders will receive in the MEDE
AMERICA reorganization may be adjusted based on a formula involving the average
closing price. This formula for determining the potential adjustment to the
exchange ratio is described in detail under the heading "Structure of the
reorganization and conversion of MEDE AMERICA common stock." Once an exchange
ratio is determined there will be no adjustment to this exchange ratio if the
market price of either MEDE AMERICA common stock or Healtheon common stock
fluctuates prior to completion of the reorganization. The share prices of both
MEDE AMERICA common stock and Healtheon common stock are subject to price
fluctuations in the market for publicly-traded equity securities and have each
experienced significant volatility. We cannot predict the market prices for
either MEDE AMERICA common stock or Healtheon common stock at any time before
the completion of the reorganization or the market price for Healtheon common
stock after the completion of the reorganization. WE ENCOURAGE YOU TO OBTAIN
CURRENT MARKET QUOTATIONS OF HEALTHEON COMMON STOCK AND MEDE AMERICA COMMON
STOCK.

FUTURE SALES OF HEALTHEON/WEBMD SHARES COULD AFFECT THE STOCK PRICE

     The market price of the Healtheon/WebMD common stock could fall
dramatically if stockholders sell large amounts of stock in the public market
following the reorganizations. These sales, or the possibility that these sales
may occur, could make Healtheon/WebMD stockholders unable to realize the value
of the merger consideration received (as measured prior to completion of the
mergers) and may make it more difficult for Healtheon/WebMD to sell equity or
equity-related securities in the future. Before the reorganizations, a
significant portion of the common stock of Healtheon and MEDE AMERICA was
subject to restrictions on transfer under federal securities law and "lock-up"
agreements with the underwriters of their IPOs, and there was no public market
for the capital stock of WebMD. Until           ,           , affiliates of
Healtheon, WebMD and MEDE AMERICA will not be able to transfer the
Healtheon/WebMD common stock due to restrictions under federal securities laws.
Thereafter, an aggregate of [          ] shares of Healtheon/WebMD common stock
will be eligible for resale in the public market. [          ] of these shares
will be subject to limitations on the volume of sales under federal securities
laws. Some Healtheon/WebMD stockholders will also have the right to demand
registration of their shares for resale.

ADDITIONAL RISKS IF THE HEALTHEON-WEBMD REORGANIZATION DOES NOT CLOSE

     MEDE AMERICA stockholders should consider these additional risks if the
Healtheon-WebMD reorganization does not occur.

BENEFITS OF HEALTHEON-WEBMD REORGANIZATION NOT AVAILABLE TO MEDE AMERICA
STOCKHOLDERS

     None of the benefits identified by Healtheon and WebMD as reasons for the
merger will be realized by MEDE AMERICA stockholders if the Healtheon-WebMD
reorganization is not completed. Nevertheless, the MEDE AMERICA reorganization
is not conditioned on the Healtheon-WebMD reorganization.

POTENTIAL IMPACT ON HEALTHEON STOCK PRICE

     The Healtheon stock price has increased from $47.00 on May 13, 1999, the
date prior to press reports indicating Healtheon and WebMD were in merger
discussions to $[ ] as of [ ], 1999. If the Healtheon-WebMD reorganization does
not occur, the Healtheon stock price may decline. Nevertheless, neither the MEDE
AMERICA reorganization nor the determination of the exchange ratio is dependent
on the closing of the Healtheon-WebMD reorganization.

ADDITIONAL RISKS IF MEDE AMERICA REORGANIZATION DOES NOT CLOSE

     WebMD stockholders should consider the following additional risk if the
MEDE AMERICA reorganization does not occur.

BENEFITS OF MEDE AMERICA MERGER NOT AVAILABLE TO WEBMD STOCKHOLDERS

     None of the benefits identified by Healtheon and MEDE AMERICA as reasons
for the merger will be realized by WebMD stockholders if the MEDE AMERICA
reorganization is not completed. Nevertheless, the Healtheon-WebMD
reorganization is not conditioned on the MEDE AMERICA reorganization.

                         Santa Clara, California 95054

PURPOSE OF THE SPECIAL MEETING

     The purpose of the Healtheon Stockholders' meeting is to vote on the
following proposals:

          1. To approve the reorganization of Healtheon that will cause
     Healtheon to become a subsidiary of a new parent company, called
     Healtheon/WebMD Corporation. In the transaction, Healtheon/ WebMD will
     issue one share of Healtheon/WebMD common stock in exchange for each
     outstanding share of Healtheon common stock.

          2. To approve the issuance of shares of Healtheon/WebMD common stock
     in the merger of a wholly owned subsidiary of Healtheon/WebMD with and into
     WebMD, Inc. as contemplated by the Agreement and Plan of Reorganization
     dated as of May 20, 1999, as amended, among Healtheon/ WebMD, Healtheon,
     WebMD, Water Acquisition Corp. and Hydrogen Acquisition Corp. Healtheon/
     WebMD will issue 1.815 shares of Healtheon/WebMD common stock for each
     share of outstanding WebMD common stock. Following the Healtheon-WebMD
     reorganization and assuming the completion of the proposed acquisition of
     MEDE AMERICA, Healtheon stockholders will own approximately 49.5% and WebMD
     stockholders will own approximately 44.4% of the combined Healtheon/WebMD.

          3. To amend Healtheon's 1996 Stock Plan, if the Healtheon-WebMD
     reorganization is completed, to increase the number of shares of common
     stock reserved for issuance under the plan from 19,107,321 shares to
     29,107,321 shares.

          4. To transact any other business that properly comes before the
     special meeting or any adjournments or postponements thereof.

RECORD DATE AND OUTSTANDING SHARES

     Only holders of record of Healtheon common stock at the close of business
on the record date are entitled to notice of and to vote at the meeting. As of
the close of business on the record date, there were           shares of
Healtheon common stock outstanding and entitled to vote, held of record by
approximately           stockholders, although Healtheon has been informed that
there are in excess of           beneficial owners.

VOTE AND QUORUM REQUIRED

     Holders of Healtheon's common stock are entitled to one vote for each share
held as of the record date. Approval of each of the proposals to be voted upon
by Healtheon stockholders requires the affirmative vote of a majority of the
total voting power of the outstanding common stock of Healtheon as of the record
date.

     On the record date, directors, executive officers and affiliates of
Healtheon as a group beneficially owned [          ] shares of Healtheon common
stock. Officers, directors and major stockholders of Healtheon have entered into
voting agreements with WebMD that obligate them to vote in favor of approval of
the Healtheon merger. As a result, if such persons vote as required by the
voting agreements, the Healtheon proposals relating to the Healtheon-WebMD
reorganization will be approved.

                                       43
<PAGE>   54

ABSTENTIONS; BROKER NON-VOTES

     Abstentions will be included in determining the number of shares present
and voting at the meeting and will have the same effect as votes against the
proposals. In the event that a broker, bank, custodian, nominee or other record
holder of Healtheon common stock indicates on a proxy that it does not have
discretionary authority to vote shares on a particular matter, which is called a
broker non-vote, those shares will not be considered for purposes of determining
the number of shares entitled to vote with respect to a particular proposal on
which the broker has expressly not voted, but will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business.

EXPENSES OF PROXY SOLICITATION

     Healtheon will pay the expenses of soliciting proxies to be voted at the
meeting. Following the original mailing of the proxies and other soliciting
materials, Healtheon and its agents also may solicit proxies by mail, telephone,
telegraph or in person. Following the original mailing of the proxies and other
soliciting materials, Healtheon will request brokers, custodians, nominees and
other record holders of Healtheon common stock to forward copies of the proxy
and other soliciting materials to persons for whom they hold shares of Healtheon
common stock and to request authority for the exercise of proxies. In such
cases, Healtheon upon the request of the record holders, will reimburse such
holders for their reasonable expenses.

PROXIES

     The proxy accompanying this proxy statement/prospectus is solicited on
behalf of the Healtheon board of directors for use at the meeting. Please
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to Healtheon. All properly signed proxies
that Healtheon receives prior to the vote at the meeting and that are not
revoked will be voted at the meeting according to the instructions indicated on
the proxies or, if no direction is indicated, to approve the Healtheon merger.
You may revoke it at any time before it is exercised at the meeting by taking
any of the following actions:

     - delivering to the secretary of Healtheon, by any means, including
       facsimile, a written notice, bearing a date later than the date of the
       proxy, stating that the proxy is revoked

     - signing and delivering a proxy relating to the same shares and bearing a
       later date prior to the vote at the meeting

     - attending the meeting and voting in person, although attendance at the
       meeting will not, by itself, revoke a proxy.

     Please note, however, that if your shares are held of record by a broker,
bank or other nominee and that stockholder wishes to vote at the meeting, the
stockholder must bring to the meeting a letter from the broker, bank or other
nominee confirming your beneficial ownership of the shares.

     Healtheon's board of directors does not know of any matter that is not
referred to herein to be presented for action at the meeting. If any other
matters are properly brought before the meeting, the persons named in the
proxies will have discretion to vote on such matters in accordance with their
best judgment.

NO APPRAISAL RIGHTS

     Holders of Healtheon common stock are not entitled to dissenters' rights or
appraisal rights with respect to the Healtheon merger or the other proposals to
be considered at the meeting.

                             Atlanta, Georgia 30326

PURPOSE OF THE SPECIAL MEETING

     The purposes of the WebMD stockholders' meeting are to vote on the
following WebMD proposals:

          Proposal 1 -- to approve and adopt the Healtheon-WebMD reorganization
     agreement and approve the WebMD merger, and

          Proposal 2 -- to approve the modification of accelerated vesting
     provisions in WebMD options to acquire an aggregate of 1,131,394 shares of
     WebMD common stock held by five WebMD employees as a result of the
     consummation of the WebMD merger, which payments may otherwise be deemed to
     constitute "parachute payments" pursuant to Internal Revenue Code section
     280G.

MAILING DATE AND RECORD DATE

     This proxy statement/prospectus is being mailed initially on or about [ ],
1999 to all stockholders of record of WebMD as of [ ], 1999. The record date for
the WebMD stockholders' meeting is the close of business on           , 1999.
WebMD will also mail this proxy statement/prospectus to any person who is a
record holder on the record date but who was not a record holder on the initial
mailing date. Only holders of record on the record date of WebMD common stock
and Series A preferred stock are entitled to vote at the WebMD stockholders'
meeting.

VOTES REQUIRED; VOTING AGREEMENTS; CONVERSION AGREEMENTS

     Pursuant to Georgia law and the WebMD articles of incorporation, in order
for WebMD Proposal 1 to be approved it must receive a majority of the votes
entitled to be cast by the holders of WebMD's:

     - common stock and Series A preferred stock;

     - Series B common stock; and

     - Series C and E common stock;

each voting as a separate voting group. As of the date this proxy
statement/prospectus was mailed, there were outstanding           shares of
common stock held by           stockholders of record,           shares of
Series A preferred stock held by           stockholders of record,
shares of Series B common stock held by one stockholder of record, and
          shares of Series C and E common stock held by           stockholders
of record. The common stock is entitled to one vote per share and the Series A
preferred stock is entitled to [     ] votes per share. The voting rights of any
holder of Series A preferred stock shall not become effective until WebMD and
the holder have made any required filings under the HSR Act with respect to the
acquisition of voting securities of WebMD and the applicable waiting period has
expired.

     The presence, in person or by proxy, of a majority of the votes entitled to
be cast by each of the three voting groups is required to constitute a quorum
for action on the WebMD proposals. Abstentions will be counted for purposes of
determining a quorum. A majority of all votes entitled to be cast by all shares
entitled to vote in each of the three voting groups must be cast in favor of
WebMD proposal 1 in order for it to be approved. In order for WebMD proposal 2
to be approved, it must receive the vote of 75% of the total number of votes
entitled to be cast by the holders of all of WebMD's common stock and Series A
preferred stock. For purposes of determining the 75% vote, shares held by the
individuals whose option

                                       45
<PAGE>   56

acceleration provisions are the subject of proposal 2 are not counted as
outstanding. An abstention or failure to vote are the same as a vote against the
proposals.

     Directors, executive officers and other affiliates of WebMD have executed
voting agreements in which they have agreed to vote their shares of common stock
and have granted irrevocable proxies to the board of directors of Healtheon to
vote their shares of common stock for the WebMD proposals. Under the
reorganization agreement, the Healtheon board is required to vote those shares
for the WebMD proposals. As a result of the voting agreements and proxies
granted under the voting agreements, the required stockholder votes for proposal
1 are assured.

     Certain holders of WebMD's preferred stock have entered into conversion
agreements providing that after           , 1999 and prior to           , 1999
either (a) they will enter into voting agreements and grant proxies to the board
of directors of Healtheon to vote their preferred stock so as to cause it to be
converted into Series D common stock prior to the effective time of the WebMD
merger or (b) their preferred shares will be automatically converted into WebMD
Series D common stock on the day prior to the record date. By virtue of the
conversion agreements, all of the shares of Series C preferred stock, Series D
preferred stock, Series E preferred stock and Series F preferred stock will be
converted into Series D common stock either the day prior to the record date or
immediately prior to the effective time of the WebMD merger.

     Unless the holders of a majority of the shares of the Series A preferred
stock elect to cause the entire Series to be converted into common stock or
unless any particular holder elects to convert his own shares of Series A
preferred stock into common stock prior to the effective time of the WebMD
merger, the shares of Series A preferred stock will remain outstanding shares of
WebMD after the WebMD merger. Unless the holders of a majority of the shares of
the Series B preferred stock elect to cause the entire Series to be converted
into common stock prior to the effective time of the WebMD merger, the shares of
Series B preferred stock will remain outstanding shares of WebMD after the WebMD
merger.

     Only the holders of WebMD common stock and Series A preferred stock will be
entitled to appraisal rights under Georgia law. Holders of other series of
preferred stock must convert their preferred stock prior to the record date for
the WebMD stockholders' meeting if they want to exercise dissenters' appraisal
rights. For more information regarding the rights of dissenting WebMD
stockholders, see the section called "Rights of dissenting WebMD stockholders"
on page 75.

PROXIES

     All shares of WebMD common stock and preferred stock that are entitled to
vote and are represented at the WebMD stockholders' meeting by properly executed
proxies received prior to or at the WebMD stockholders' meeting and not duly and
timely revoked will be voted at the WebMD stockholders' meeting in accordance
with the instructions indicated on such proxies. If no such instructions are
indicated, such proxies will be voted for both WebMD proposals.

     Execution of a proxy does not affect a stockholder's right to attend the
meeting and, other than in the case of irrevocable proxies executed in
connection with the voting agreements, does not prevent the stockholder from
voting in person at the meeting. Any proxy, other than those executed in
connection with the execution of a voting agreement, may be revoked by a
stockholder at any time before it is exercised by delivering a written
revocation or a later-dated proxy to the secretary of WebMD, or by attending the
meeting and voting in person. Any written notice of revocation or subsequent
proxy should be sent so as to be delivered to WebMD at 400 The Lenox Building,
3399 Peachtree Road NE, Atlanta GA 30326, attention: Corporate Secretary, or
hand-delivered to the corporate secretary of WebMD, in each case at or before
the taking of the vote at the WebMD stockholders' meeting.

RECOMMENDATION OF WEBMD BOARD OF DIRECTORS

     The WebMD board of directors has unanimously approved the Healtheon-WebMD
reorganization agreement and the transactions contemplated thereby and has
determined that the WebMD merger is fair

                                       46

to, and in the best interest of, WebMD and its stockholders. THE WEBMD BOARD
UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE
HEALTHEON-WEBMD REORGANIZATION AGREEMENT AND APPROVAL OF THE WEBMD MERGER.

     The WebMD board of directors has unanimously approved the modification of
accelerated vesting provisions in WebMD options held by five employees to
purchase an aggregate of 1,131,394 shares of WebMD common stock as described in
more detail in the section entitled "The Healtheon-WebMD reorganization
agreement -- vesting of certain employee options" and has determined that such
acceleration is in the best interest of WebMD and its stockholders. THE WEBMD
BOARD UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR OF APPROVAL OF THE MODIFICATION OF
ACCELERATED VESTING PROVISIONS IN CERTAIN WEBMD STOCK OPTIONS HELD BY THESE
WEBMD EMPLOYEES.

PURPOSE OF THE SPECIAL MEETING

     The special meeting is being held so you can consider and vote upon a

                       THE HEALTHEON-WEBMD REORGANIZATION

     This section of the proxy statement/prospectus describes the proposed
Healtheon-WebMD reorganization. While we believe that the description covers the
material terms of the reorganization and the related transactions, this summary
may not contain all of the information that is important to you. You should
carefully read this entire document and the other documents we refer to for a
more complete understanding of the reorganization.

BACKGROUND OF THE HEALTHEON-WEBMD REORGANIZATION AND RELATED AGREEMENTS

     On April 8, 1999 Mr. Long called Mr. Arnold. That evening, Mr. Long and Mr.
Arnold met for dinner in Atlanta, Georgia to discuss the strategic objectives of
Healtheon and WebMD and to discuss a partnership between the two companies.

     At the invitation of Mr. Long, James H. Clark, Healtheon's Chairman, Mr.
Long, Mr. Arnold and a representative from BancBoston Robertson Stephens met for
dinner in Atlanta, Georgia on the evening of April 11, 1999 and discussed the
businesses of Healtheon and WebMD and the potential of a business combination
between the two companies. At that time, WebMD was concluding negotiations with
Microsoft for a $100 million purchase by Microsoft of WebMD's Series E
convertible preferred stock at an effective price of $54.17 per common share as
well as the terms of a strategic relationship between Microsoft and WebMD.
Moreover, on April 10, 1999, Microsoft had commenced a tender offer for
approximately 27.8% of the equity interests in WebMD for $54.17 per common
share. A condition to Microsoft's obligation to purchase shares in the tender
offer was that WebMD not authorize, propose or announce any significant business
combination. In addition, the terms of the Series E preferred stock that
Microsoft had agreed to purchase from WebMD gave Microsoft the right to approve
business combinations involving WebMD. Accordingly, WebMD informed Healtheon of
this restriction and informed Microsoft of the discussions held on April 11,
1999.

     On April 12, 1999, Mr. Long and other members of Healtheon's management
team met with officials from Microsoft to discuss the business of Healtheon and
a possible business combination of Healtheon and WebMD. On April 14, 1999,
officials of Microsoft and senior executives of WebMD held a conference call
during which Microsoft encouraged WebMD to explore a possible business
combination with Healtheon.

     On April 19, 1999, Morgan Stanley was formally engaged by Healtheon to
provide it financial advisory services in connection with the Healtheon-WebMD
reorganization.

     On April 26, 1999 Mr. Long and Mr. Clark met with representatives from
Morgan Stanley in Los Angeles, California to outline the potential terms of a
merger between Healtheon and WebMD. Later that day, Mr. Long, Mr. Clark and L.
John Doerr, a director of Healtheon, met with Mr. Arnold for dinner to discuss a
potential combination between the two companies.

     On April 27, 1999, Mr. Clark delivered a letter to Mr. Arnold outlining
terms of a potential business combination for purposes of continuing and
focusing the earlier discussions. At the invitation of Mr. Arnold, on May 3,
1999, Mr. Clark, Mr. Long and a representative from Morgan Stanley met for
dinner in Atlanta, Georgia with Mr. Arnold, other senior executives of WebMD and
WebMD outside directors U. Bertram Ellis, Jr., S. Taylor Glover and Jouko J.
Rissanen for the purpose of discussing the potential benefits of a business
combination.

     On May 4, 1999 in the offices of WebMD, Mr. Long, Mr. Clark and a
representative from Morgan Stanley met with Mr. Arnold, other representatives of
WebMD's senior management team and BancBoston Robertson Stephens to discuss the
terms of a possible business combination between Healtheon and WebMD. In
addition, on May 4 Mr. Long, Mr. Clark, other members of Healtheon's senior
management team and representatives from Morgan Stanley conducted business due
diligence on WebMD.

     On May 6, 1999, Healtheon and WebMD signed a Mutual Non-disclosure
Agreement. On May 6 and 7, 1999, senior executives of both companies and their
respective legal and financial advisors met in

                                       50
<PAGE>   61

Palo Alto, California to continue due diligence and the process of negotiating
the terms of the transaction. These discussions continued through the following
week in Palo Alto, California.

     During these discussions it was agreed with representatives of Microsoft
that Microsoft would increase the amount of its investment in WebMD from $100
million to $250 million, at an effective price per WebMD common share of $54.17,
with the additional $150 million conditioned upon the closing of WebMD's merger
with Healtheon.

     On May 13, 1999, Healtheon's board of directors held a special meeting to
discuss the proposed business combination with WebMD. At this meeting,
Healtheon's senior management and financial and legal advisors presented to the
board the terms of the proposed combination with WebMD and the status of
business, financial and legal due diligence of the transaction.

     On May 14, 1999, it was reported in the press that Healtheon and WebMD were
having discussions concerning a possible business combination. Over the weekend
of May 15 - 16, 1999, and into the following week the senior executives,
attorneys and financial advisors for Healtheon and WebMD continued to work to
finalize the Healtheon-WebMD reorganization agreement and other documents
evidencing the various arrangements, including the Microsoft investment and
revisions to its strategic relationship as well as the investments by and
contracts with the other purchasers of WebMD's Series E preferred stock.

     On May 16, 1999, Healtheon's board of directors held a special meeting to
discuss the progress of negotiations of the proposed business combination
transaction, ultimately adjourning the meeting until a later time.

     On May 17, 1999, Healtheon's board of directors reconvened the special
meeting of the board at which the board reviewed with its senior management and
financial and legal advisors the results of the negotiations with WebMD. At this
meeting, representatives of Morgan Stanley presented its financial analysis of
the proposed transaction and expressed their opinion that the exchange ratio
provided for by the reorganization agreement was fair from a financial point of
view to Healtheon. Healtheon's board reviewed a draft of the reorganization
agreement and posed questions to representatives of Wilson Sonsini Goodrich &
Rosati, Healtheon's legal counsel, regarding the document and the terms of the
transaction. Following discussions, Healtheon's board approved the
reorganization, the reorganization agreement, related agreements, and the
issuance of shares to WebMD stockholders in the transaction. Healtheon's board
determined to recommend to the Healtheon stockholders its approval of the
reorganization and the issuance of shares to WebMD stockholders.

     On May 19, 1999, Healtheon's board convened a special meeting to discuss
the results of subsequent negotiations of the reorganization. After posing
questions to representatives of Wilson Sonsini Goodrich & Rosati and following
discussions, the board approved the transaction.

     A meeting of the WebMD board was convened in New York City on May 16, 1999,
during which WebMD's senior management, financial advisors and legal counsel
outlined the terms of the proposed combination with Healtheon and related
transactions with Microsoft and others and described the status of the
negotiations.

     The meeting was adjourned and reconvened several times over the next four
days, with WebMD's senior management, financial advisors and legal counsel
advising the WebMD board of the progress of the negotiations at each meeting. At
its meeting held on May 17, 1999, the WebMD board approved by unanimous vote the
amendments to WebMD's Investment Agreement with Microsoft, to provide for the
increase in Microsoft's investment from $100 million to $250 million, with the
additional $150 million conditioned upon the closing of the merger, and for up
to $150 million of investments by other strategic investors.

     At the WebMD board meeting held on May 19, 1999, WebMD senior management
and legal counsel discussed the results of the negotiations with Healtheon and
the terms of the proposed reorganization agreement, the voting agreements and
the conversion agreements. At this meeting representatives of BancBoston
Robertson Stephens, Inc. presented an analysis of the financial terms of the
proposed

                                       51
<PAGE>   62

reorganization and expressed their opinion that the exchange ratio was fair to
the holders of WebMD stock from a financial point of view. In addition, the
WebMD board of directors reviewed a draft of the reorganization agreement and a
representative from Nelson Mullins Riley & Scarborough, L.L.P. answered
questions regarding the document from the board of directors. Following these
presentations and other discussions, the WebMD board approved by unanimous vote
the terms of the reorganization and the reorganization agreement substantially
in the form presented, and authorized a committee of the WebMD board consisting
of Messrs. Arnold, Gilbertson, Draughon, Heekin and Rissanen to complete the
negotiations and execution of the reorganization agreement.

     During the evening of May 19 and early morning of May 20 the negotiations
of reorganization agreement were completed. The special committee heard an
updated financial analysis and opinion from BancBoston Robertson Stephens and
approved the final agreement at a meeting held at 6:30 a.m. eastern time, May
20, 1999. At a meeting of the WebMD board held at 9:00 a.m. eastern time, May
20, 1999, representatives of BancBoston Robertson Stephens again presented its
updated financial analysis and opinion that the exchange ratio was fair to the
stockholders of WebMD from a financial point of view, counsel reviewed the terms
of the final reorganization agreement and related documents, and the
reorganization agreement and the WebMD merger were ratified and approved by the
unanimous vote of the WebMD board.

JOINT REASONS FOR THE HEALTHEON-WEBMD REORGANIZATION

     Healtheon's and WebMD's boards of directors have determined that the
Healtheon-WebMD reorganization is fair to, and in the best interests of, the
stockholders of their respective companies. They concluded that the combined
company following the Healtheon-WebMD reorganization would have the potential to
realize long-term improved operating and financial results and a stronger
competitive position. Potential mutual benefits identified by the boards of
directors include the following:

     - the combination of WebMD's brand recognition and existing strategic
       relationships with Healtheon's e-commerce transaction platform and
       industry relationships will enable Healtheon/ WebMD to move decisively
       toward Healtheon's and WebMD's key strategic goal of offering a
       comprehensive, integrated Web-based solution for the administrative,
       communications and information needs of the healthcare industry.

     - the combination of two leading providers of end-to-end Internet solutions
       to the healthcare industry will better position Healtheon/WebMD to
       achieve increased subscriber penetration among physicians, payers,
       providers and other healthcare industry participants.

     - expanding each company's connected network of customers and strategic
       partners, accelerating Healtheon/WebMD's efforts toward achieving
       critical mass in the healthcare industry and strengthening its
       competitive position. Healtheon/WebMD is expected to offer connectivity
       and transactions for physicians, consumers and healthcare institutions
       over a network consisting of approximately 540 payers, 180,000
       physicians, 1,100 hospitals, 42,000 pharmacies, 10,000 dentists and 200
       affiliate partners.

     - increasing Healtheon/WebMD's transaction volume.

     - broadening each company's offerings of Internet-based healthcare-related
       transactions services, and creating enhanced cross-selling opportunities.

     - increasing the speed at which Internet transaction processing streamlines
       inefficient manual and paper-based processes.

     - enhancing the quality and depth of patient-doctor communications.

     - creating a strong combined management team.

HEALTHEON'S REASONS FOR THE HEALTHEON-WEBMD REORGANIZATION

     At the meeting held on May 19, 1999, the board of directors of Healtheon
concluded that the merger was in the best interests of Healtheon and determined
to recommend that the stockholders approve the stockholder proposals relating to
the merger.

     The decision of the board of directors of Healtheon was based upon several
potential benefits of the merger, including the following, the order of which
does not necessarily reflect their relative significance:

     - EXPANSION OF BUSINESS MODEL TO INCLUDE CONSUMER AND HEALTHCARE
       PROFESSIONAL WEB SITES. To date, Healtheon has focused primarily on the
       development and deployment of a mission-critical transaction engine and
       related applications to facilitate Internet based healthcare transactions
       between payers, providers and institutions. To date, WebMD has focused
       its efforts on the development of consumer and healthcare professional
       web sites that provide authoritative content, on line communities,
       practice management services and personalized service to both healthcare
       professionals and consumers. Healtheon believes that the WebMD physician
       and consumer portals will be essential to accelerating Healtheon
       sponsored transactions, as physicians today initiate most healthcare
       transactions, with consumers' choice playing an increasing role.

     - CREATION OF COMPLETE END-TO-END HEALTHCARE E-COMMERCE SOLUTION. Healtheon
       believes that, through the Healtheon-WebMD reorganization,
       Healtheon/WebMD will create a leading end-to-end healthcare e-commerce
       solution with the ability to facilitate business-to-business,
       consumer-to-business and business-to-consumer transactions.

     - EXPANSION OF STRATEGIC PARTNERSHIPS. The reorganization will provide
       Healtheon with additional strategic relationships with healthcare and
       technology industry leaders to augment its current strategic alliances.
       WebMD has business relationships with Microsoft, Intel, SOFTBANK,
       Excite@Home, Lycos, DuPont, CNN and other leading institutions. In
       addition, many of these leading companies are also investors in WebMD.
       These strategic partnerships will help the combined company achieve its
       objectives of connectivity and transactions between consumers, payers,
       providers and institutions, establish the Healtheon/WebMD brand and
       contribute towards the establishment of a common Internet healthcare
       technology platform.

     - DIVERSIFICATION OF FINANCIAL BUSINESS MODEL. To date, Healtheon has
       focused on a financial business model that is based on transactions
       between payers, providers and institutions. To date, WebMD has focused on
       a financial business model that includes subscriptions, sponsorships and
       advertising. Additionally, Healtheon believes that the cross-selling
       opportunities are substantial given the complementary service offerings
       and customer bases of the two companies.

     The foregoing discussion of the information and factors considered by the
Healtheon board is not intended to be exhaustive but is believed to include all
material factors considered by Healtheon's board. In view of the complexity and
wide variety of information and factors, both positive and negative, considered
by the Healtheon board, it did not find it practical to quantify, rank or
otherwise assign relative or specific weights to the factors considered. In
addition, the Healtheon board did not reach any specific conclusion with respect
to each of the factors considered, or any aspect of any particular factor, but,
rather, conducted an overall analysis of the factors described above, including
discussions with Healtheon's management and legal, financial and accounting
advisors. In considering the factors described above, individual members of the
Healtheon board may have given different weight to different factors. The
Healtheon board considered all these factors as a whole and believed the factors
supported its determination to approve the reorganization. After taking into
consideration all of the factors set forth above, Healtheon's board concluded
that the reorganization was fair to, and in the best interests, of Healtheon and
that Healtheon should proceed with the reorganization.

RECOMMENDATION OF HEALTHEON'S BOARD OF DIRECTORS

     After carefully evaluating these factors, both positive and negative, the
board of directors of Healtheon has determined that the reorganization is in the
best interests of Healtheon and recommends
                                       53
<PAGE>   64

that they vote for approval and adoption of the reorganization agreement,
approval of the Healtheon merger and approval of the issuance of shares in the
WebMD merger.

     In considering the recommendation of the Healtheon board with respect to
the reorganization, you should be aware that one director of Healtheon has
interests in the reorganization that are different from, or are in addition to
the interests of Healtheon stockholders generally. Please see the section
entitled "Interests of directors, officers and affiliates in the Healtheon-WebMD
reorganization" on page 68.

WEBMD'S REASONS FOR THE HEALTHEON-WEBMD REORGANIZATION

     In addition to the anticipated joint benefits described above, WebMD's
board of directors believes that the following are additional reasons the
Healtheon-WebMD reorganization will be beneficial to WebMD and for stockholders
of WebMD to vote for approval of the reorganization agreement and the WebMD
merger:

     - the implied value of the WebMD merger consideration on the date of the
       reorganization agreement of $145.65 (based on the closing price of
       Healtheon common stock on the day prior to the WebMD board's approval of
       the merger) represented a premium to the $54.17 price per common share
       that Microsoft agreed to pay for its initial strategic investment and in
       its tender offer.

     - the opinion of BancBoston Robertson Stephens, WebMD's financial advisor,
       that the WebMD exchange ratio was fair to WebMD stockholders from a
       financial point of view. This opinion is subject to assumptions and
       limitations noted in the opinion and described under "Opinion of WebMD's
       financial advisor," and stockholders should carefully read both that
       section and the opinion which is attached to this document as Annex D.
       The opinion of BancBoston Robertson Stephens is directed to WebMD's board
       of directors and does not constitute a recommendation to stockholders of
       WebMD on how they should vote at, or take any other action in connection
       with, the special meeting for the WebMD merger.

     - the opportunity of WebMD stockholders to participate in the potential
       growth of Healtheon/ WebMD following the WebMD merger or to realize their
       investment by selling their Healtheon/ WebMD shares in a public market;

     - the liquidity afforded WebMD's stockholders upon exchange of their shares
       in WebMD, which are not publicly traded, for shares in Healtheon/WebMD,
       which will be publicly traded; and

     - the greater liquidity anticipated to be afforded WebMD's stockholders
       upon the closing of the WebMD merger as compared to the closing of
       WebMD's own previously proposed initial public offering because a larger
       number of shares of Healtheon/WebMD are anticipated to be outstanding
       after the reorganization than would be outstanding after a WebMD initial
       public offering and the resulting likelihood of greater trading volume
       and increased coverage by investment research and analyst reports.

     The WebMD board also identified and considered a variety of potential
negative factors concerning the reorganization, including, but not limited to:

     - the risk to WebMD's stockholders that the value to be received in the
       reorganization could decline significantly from the indicated value on
       the date of the reorganization agreement due to potential declines in the
       trading price of Healtheon stock, which has been volatile since
       Healtheon's initial public offering;

     - the potential difficulty of sharing of control over the future operations
       of Healtheon/WebMD following the reorganization, including the difficulty
       of integrating personnel, administrative functions and strategic
       relationships;

     - the risk that the potential strategic benefits sought in the
       reorganization might not be realized;

     - the possibility that the WebMD merger might not be consummated and the
       potential adverse effects of the public announcement of the merger on:
                                       54
<PAGE>   65

      (a) WebMD's ability to leverage its existing strategic relationships and
          attract new strategic partners and distribution channels;

      (b) WebMD's ability to obtain additional subscribers to its services;

      (c) WebMD's ability to acquire other businesses useful or complementary to
          its business;

      (d) WebMD's ability to attract and retain key employees; and

      (e) WebMD's overall competitive position.

     - the risk that, despite the efforts of Healtheon and WebMD, key technical
       and management personnel might not remain employees of Healtheon/WebMD
       following the closing of the reorganization; and

     - the other risks more fully described under the section entitled "Risk
       Factors" beginning on page   .

     After due consideration, the WebMD board concluded that the risks
associated with the proposed reorganization were outweighed by the potential
benefits.

     During the process of evaluating the reorganization, WebMD's board also
considered the provisions of the reorganization agreement that prohibited
solicitation of third-party bids and the acceptance, approval or recommendation
of any unsolicited third-party bids and determined that the benefits of the
reorganization with Healtheon justified these conditions and proceeded to
approve the reorganization.

     The foregoing discussion of the information and factors considered by the
WebMD board is not intended to be exhaustive but is believed to include all
material factors considered by WebMD's board. In view of the complexity and wide
variety of information and factors, both positive and negative, considered by
the WebMD board, it did not find it practical to quantify, rank or otherwise
assign relative or specific weights to the factors considered. In addition, the
WebMD board did not reach any specific conclusion with respect to each of the
factors considered, or any aspect of any particular factor, but, rather,
conducted an overall analysis of the factors described above, including
discussions with WebMD's management and legal, financial and accounting
advisors. In considering the factors described above, individual members of the
WebMD board may have given different weight to different factors. The WebMD
board considered all these factors as a whole and believed the factors supported
its determination to approve the reorganization. After taking into consideration
all of the factors set forth above, WebMD's board concluded that the
reorganization was fair to, and in the best interests, of WebMD and its
stockholders and that WebMD should proceed with the reorganization.

RECOMMENDATION OF WEBMD'S BOARD OF DIRECTORS

     After carefully evaluating these factors, both positive and negative, the
board of directors of WebMD has determined that the Healtheon-WebMD
reorganization is in the best interests of the WebMD stockholders and
unanimously recommends that you vote for approval and adoption of the
reorganization agreement and approval of the WebMD merger.

     In considering the recommendation of the WebMD board with respect to the
reorganization, you should be aware that certain directors and officers of WebMD
have interests in the reorganization that are different from, or are in addition
to the interests of WebMD stockholders generally. Please see the section
entitled "Interests of directors, officers and affiliates in the Healtheon-WebMD
reorganization" on page 68.

OPINION OF HEALTHEON'S FINANCIAL ADVISOR

     Under an engagement letter dated April 19, 1999, Healtheon retained Morgan
Stanley to provide it with financial advisory services and a financial fairness
opinion in connection with the Healtheon/WebMD reorganization. The Healtheon
board of directors selected Morgan Stanley to act as Healtheon's financial
advisor based on Morgan Stanley's qualifications, expertise and reputation and
its knowledge of the business and affairs of Healtheon. At the meeting of the
Healtheon board of directors on May 17, 1999, Morgan Stanley rendered its oral
opinion, subsequently confirmed in writing, that as of May 17, 1999,
                                       55
<PAGE>   66

based upon and subject to the various considerations set forth in the opinion,
the exchange ratio pursuant to the reorganization agreement was fair from a
financial point of view to Healtheon. Morgan Stanley subsequently confirmed its
May 17, 1999 opinion by delivering to the Healtheon board of directors a written
opinion dated as of May 20, 1999.

     You should consider the following when reading the discussion of the
Healtheon's financial advisor in this document.

     - You are urged to read the full text of the written opinion of Morgan
       Stanley dated May 20, 1999 that is attached as Annex C to this document
       and sets forth, among other things, the assumptions made, procedures
       followed, matters considered and limitations on the scope of the review
       undertaken by Morgan Stanley in rendering its opinion.

     - Morgan Stanley's opinion is directed to the Healtheon board of directors
       and addresses only the fairness of the exchange ratio pursuant to the
       reorganization agreement from a financial point of view to Healtheon as
       of the date of the opinion.

     - Morgan Stanley's opinion does not address any other aspect of the
       reorganization and does not constitute a recommendation to any holder of
       Healtheon common stock as to how to vote at the Healtheon special
       meeting.

     - The summary of the opinion of Morgan Stanley set forth in this document,
       while materially complete, is qualified in its entirety by reference to
       the full text of the opinion.

     In connection with rendering its opinion, Morgan Stanley, among other
things:

     - reviewed publicly available financial statements and other information of
       Healtheon, including the pro forma impact of Healtheon's proposed
       acquisition of MEDE AMERICA, referred to as Pro Forma Healtheon;

     - reviewed internal financial statements and other financial and operating
       data concerning WebMD and Pro Forma Healtheon prepared by the managements
       of WebMD and Healtheon, respectively;

     - analyzed financial projections pro forma for the investments made by
       Microsoft and other investors pursuant to the investment agreement, as
       well as other investments by other investors as contemplated by the
       reorganization agreement, relating to WebMD prepared by the management of
       WebMD;

     - reviewed and discussed with the senior managements of Healtheon and WebMD
       the strategic rationale for the reorganization;

     - discussed the past and current operations and financial condition and the
       prospects of Pro Forma Healtheon, including information relating to
       strategic, financial and operational synergies and benefits anticipated
       from the reorganization, with senior executives of Healtheon;

     - discussed the past and current operations and financial condition and the
       prospects of WebMD, including information relating to strategic,
       financial and operational benefits anticipated from the reorganization,
       with senior executives of WebMD;

     - discussed the effect of the strategic investments on the business and
       trading prospects of each of Pro Forma Healtheon and WebMD, including
       information relating to strategic, financial and operational benefits
       anticipated from each strategic investment, with senior executives of
       Healtheon and WebMD, respectively;

     - discussed the effect of the strategic investments on the business and
       trading prospects of Pro Forma Healtheon and WebMD pro forma for the
       merger, including information relating to strategic, financial and
       operational benefits anticipated from each strategic investment, with
       senior executives of Healtheon and WebMD;

                                       56
<PAGE>   67

     - reviewed the pro forma impact of the reorganization on the income
       statement of Pro Forma Healtheon;

     - reviewed the reported prices and trading activity of the Healtheon common
       stock;

     - compared the financial performance of Pro Forma Healtheon and WebMD and
       the prices and trading activity of the Healtheon common stock with that
       of publicly-traded companies comparable to Healtheon and WebMD and their
       securities;

     - participated in negotiations and discussions among representatives of
       Healtheon and WebMD;

     - reviewed the reorganization agreement and the investment agreement, as
       well as documents related to the reorganization and the strategic
       investments;

     - reviewed the Form S-1 of WebMD (File No. 333-7135) filed with the
       Securities and Exchange Commission, as amended on February 26, 1999, as
       well as documents related to the foregoing; and

     - performed such other analysis and considered such other factors as Morgan
       Stanley deemed appropriate.

     Morgan Stanley assumed and relied upon, without independent verification,
the accuracy and completeness of the information reviewed by it for the purposes
of its opinion. With respect to the internal financial statements and other
financial and operating data, including forecasts, and discussions relating to
the strategic, financial and operational benefits anticipated from the strategic
investments and from the reorganization provided by Healtheon and WebMD, Morgan
Stanley assumed that they have, in each case, been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the prospects
of Pro Forma Healtheon and WebMD. Morgan Stanley relied upon the assessment by
the managements of Healtheon and WebMD of their ability to retain key employees
of Pro Forma Healtheon and WebMD. Morgan Stanley also relied upon, without
independent verification, the assessment by the managements of Healtheon and
WebMD of the following:

     - the strategic and other benefits expected to result from the
       reorganization

     - the timing and risks associated with the integration of Pro Forma
       Healtheon and WebMD

     - the validity of, and risks associated with, Pro Forma Healtheon's and
       WebMD's existing and future products and technologies

     Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities or technology of Pro Forma Healtheon and WebMD, nor had
Morgan Stanley been furnished with any such appraisals. In addition, Morgan
Stanley assumed that the reorganization will be treated as a tax-free
reorganization and/or exchange, pursuant to the Internal Revenue Code of 1986
and will be consummated in accordance with the terms set forth in the
reorganization agreement. Morgan Stanley also assumed that all strategic
investments will be consummated in accordance with the terms of their respective
agreements, and that the Microsoft tender offer would not materially delay, or
otherwise have a material adverse effect on, the consummation of the
reorganization. Morgan Stanley's opinion is necessarily based on financial,
economic, market and other conditions as in effect on, and the information made
available to it as of the date of its opinion.

     The following is a brief summary of the analyses performed by Morgan
Stanley in connection with the preparation of its opinion letter dated May 20,
1999. Selected summaries of financial analyses include information presented in
tabular format. In order to understand fully the financial analyses used by
Morgan Stanley, the tables must be read together with the text of each summary.

     No company utilized in the peer group comparison analysis is identical to
Pro Forma Healtheon. In evaluating the peer groups, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond control of Healtheon and WebMD, such as the impact of competition on the
businesses of Pro Forma Healtheon and WebMD and the industry generally, industry
growth and the absence of any adverse material change in the financial condition
and prospects of Pro Forma Healtheon, WebMD or the

industry or in the financial markets in general. Mathematical analysis, such as
determining the average or median, is not in itself a meaningful method of using
peer group data.

     Discounted Equity Value. Morgan Stanley performed an analysis of the
present value per share of the implied value of WebMD on a standalone basis
based on WebMD's future equity value. Morgan Stanley observed the following,
based on a range of revenue estimates from WebMD management with growth
estimates ranging from 50% to 100%, for the calendar years 2001 and 2002,
assuming calendar year 2000 revenue multiples of approximately 20 to 30:

     Pro Forma Reorganization Analysis. Morgan Stanley analyzed the pro forma
impact of the reorganization on the combined company's projected earnings per
share for calendar year 1999 and 2000. Such analysis was based on earnings
projections by WebMD management for WebMD and by securities research analysts
for Pro Forma Healtheon.

     - Morgan Stanley observed that the reorganization would result in earnings
       per share dilution for Pro Forma Healtheon, prior to giving effect to any
       synergies, of $0.02 for calendar year 1999 and earnings per share
       accretion of $0.02 for calendar year 2000 on a cash earnings basis,
       defined as earnings excluding non-cash charges such as goodwill, as
       reported by securities research analysts.

     - Morgan Stanley observed that the reorganization would result in earnings
       per share dilution for Pro Forma Healtheon, prior to giving effect to any
       synergies, of approximately $4.34 for calendar year 1999 and
       approximately $8.49 for calendar year 2000 on GAAP earnings estimates
       reported by securities research analysts.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, Morgan Stanley believes that selecting any
portion of its analyses, without considering all analyses, would create an
incomplete view of the process underlying its opinion. In addition, Morgan
Stanley may have given various analyses and factors more or less weight than
other analyses and factors, and may have deemed various assumptions more or less
probable than other assumptions, so that the ranges of valuations resulting from
any particular analysis described above should not be taken to be Morgan
Stanley's view of the actual value of Pro Forma Healtheon or WebMD. In
performing its analyses, Morgan Stanley made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Healtheon or WebMD. Any
estimates contained in Morgan Stanley's analyses are not necessarily indicative
of future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates.

     The analyses performed were prepared solely as part of Morgan Stanley's
analysis of the fairness of the exchange ratio pursuant to the reorganization
agreement from a financial point of view to Healtheon

                                       60
<PAGE>   71

and were conducted in connection with the delivery of the Morgan Stanley
opinion. The analyses do not purport to be appraisals or to reflect the prices
at which Healtheon or WebMD might actually be sold.

     The exchange ratio pursuant to the reorganization agreement was determined
through arm's-length negotiations between Healtheon and WebMD and was approved
by the Healtheon board of directors. Morgan Stanley provided advice to Healtheon
during these negotiations; however, Morgan Stanley did not recommend any
specific exchange ratio to Healtheon or that any specific exchange ratio
constituted the only appropriate exchange ratio for the reorganization.

     In addition, Morgan Stanley's opinion and presentation to the Healtheon
board of directors was one of many factors taken into consideration by
Healtheon's board of directors in making its decision to approve the
reorganization. Consequently, the Morgan Stanley analyses as described above
should not be viewed as determinative of the opinion of the Healtheon board of
directors with respect to the exchange ratio or of whether the Healtheon board
of directors would have been willing to agree to a different exchange ratio.

     The Healtheon board of directors retained Morgan Stanley based upon Morgan
Stanley's qualifications, experience and expertise. Morgan Stanley is an
internationally recognized investment banking and advisory firm. Morgan Stanley,
as part of its investment banking business, is continuously engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate, estate and other purposes. In the past, Morgan Stanley
and its affiliates have provided financing and advisory services for Healtheon,
Microsoft and other parties to the strategic investments and have received fees
for rendering these services. Morgan Stanley is also an equity owner of
Healtheon as a result in Morgan Stanley's participation in a private placement.
In the ordinary course of Morgan Stanley's trading and brokerage activities,
Morgan Stanley or its affiliates may at any time hold long or short positions,
may trade or otherwise effect transactions, for its own account or for the
account of customers in the equity securities of Healtheon, Microsoft or any of
the other parties to the strategic investments.

     Under the engagement letter, Morgan Stanley provided financial advisory
services and a financial fairness opinion in connection with the merger, and
Healtheon agreed to pay Morgan Stanley a customary fee. In addition, Healtheon
has also agreed to indemnify Morgan Stanley and its affiliates, their respective
directions, officers, agents and employees and each person, if any controlling
Morgan Stanley or any of its affiliates against liabilities and expenses,
including liabilities under the federal securities laws, arising out of Morgan
Stanley's engagement.

OPINION OF WEBMD'S FINANCIAL ADVISOR

     On March 12, 1999, WebMD and BancBoston Robertson Stephens executed an
engagement letter (supplemented by a letter dated April 20, 1999) pursuant to
which BancBoston Robertson Stephens was engaged to render an opinion as to the
fairness of the exchange ratio, from a financial point of view, to the
stockholders of WebMD.

     On May 19, 1999 at a meeting of the WebMD board held to evaluate the
proposed Healtheon/ WebMD reorganization, BancBoston Robertson Stephens
delivered to the WebMD board its oral opinion, subsequently confirmed in
writing, that as of May 19, 1999 and based on the matters described in the
opinion, the exchange ratio was fair from a financial point of view to the
stockholders of WebMD (with the exception of Healtheon, any affiliate of
Healtheon and any holder of WebMD stock who has exercised dissenters' rights).
The exchange ratio was determined through negotiations between the respective
managements of WebMD and Healtheon. Although BancBoston Robertson Stephens did
assist the management of WebMD in those negotiations, it was not asked by, and
did not recommend to, WebMD that any specific exchange ratio constituted the
appropriate exchange ratio for the WebMD merger. BancBoston Robertson Stephens
also assisted WebMD's management in the negotiations leading to an agreement on
principal structural terms of the transaction.

consequences of the WebMD merger, and the BancBoston Robertson Stephens opinion
as to the fairness of the exchange ratio does not take into account the
particular tax status or position of any stockholder of WebMD. In furnishing its
opinion, BancBoston Robertson Stephens was not engaged as an agent or fiduciary
of WebMD's stockholders or any other third party.

     The full text of the BancBoston Robertson Stephens opinion, which sets
forth, among other things, assumptions made, matters considered and limitations
on the review undertaken, is attached as Annex D and is incorporated in this
proxy statement/prospectus by reference. Stockholders of WebMD are urged to read
the BancBoston Robertson Stephens opinion in its entirety. The BancBoston
Robertson Stephens opinion was prepared for the benefit and use of the WebMD
board in its consideration of the Healtheon-WebMD reorganization and does not
constitute a recommendation to stockholders of WebMD as to how they should vote
at, or take any action in connection with, the special meeting for the
Healtheon-WebMD reorganization. The BancBoston Robertson Stephens opinion does
not address:

     - the relative merits of the Healtheon-WebMD reorganization and any other
       transactions;

     - business strategies discussed by the WebMD board as alternatives to the
       reorganization; or

     - the underlying business decision of the WebMD board to proceed with the
       reorganization process.

     The summary of the BancBoston Robertson Stephens opinion set forth in this
proxy statement/ prospectus is qualified in its entirety by reference to the
full text of the BancBoston Robertson Stephens opinion.

     In connection with the preparation of the BancBoston Robertson Stephens
opinion, BancBoston Robertson Stephens, among other things:

     - reviewed publicly available financial statements and other business and
       financial information of Healtheon;

     - reviewed internal financial statements and other financial and operating
       data concerning WebMD and Healtheon, including information relating to
       strategic, financial and operational benefits anticipated from the WebMD
       merger, prepared by the managements of WebMD and Healtheon;

     - reviewed financial forecasts and other forward looking financial
       information prepared by the managements of WebMD and Healtheon;

       concerning the businesses, past and current operations, financial
       condition and future prospects of both WebMD and Healtheon, independently
       and combined, including discussions with the managements of WebMD and
       Healtheon concerning cost savings and other synergies that are expected
       to result from the WebMD merger as well as their views regarding the
       strategic rationale for the WebMD merger;

     - reviewed the financial terms and conditions set forth in the
       reorganization agreement;

     - reviewed the stock price and trading history of Healtheon;

     - reviewed the valuations of publicly traded companies deemed comparable to
       WebMD;

     - compared the financial terms of the WebMD merger with the financial
       terms, to the extent publicly available, of other transactions that we
       deemed relevant;

     - reviewed the pro forma impact of the WebMD merger on Healtheon's revenues
       and cash earnings per share;

     - reviewed and considered in the analysis, information prepared by members
       of management of WebMD and Healtheon relating to the relative
       contributions of WebMD and Healtheon to the revenues of the combined
       company;

                                       62

     - prepared an analysis of WebMD with respect to an initial public offering;

     - participated in discussions and negotiations among representatives of
       WebMD and Healtheon and their financial and legal advisors; and

     - made such other studies and inquiries, and reviewed such other data as
       BancBoston Robertson Stephens deemed relevant.

     In BancBoston Robertson Stephens' review and analysis and in arriving at
its opinion, BancBoston Robertson Stephens assumed and relied upon the accuracy
and completeness of all of the financial and other information provided to it
including information furnished to BancBoston Robertson Stephens orally or
otherwise discussed with BancBoston Robertson Stephens by management of WebMD
and Healtheon, or publicly available and has neither attempted to verify, nor
assumed responsibility for verifying, any of such information. BancBoston
Robertson Stephens has relied upon the assurances of management of WebMD and
Healtheon that neither is aware of any facts that would make such information
inaccurate or misleading. Furthermore, BancBoston Robertson Stephens did not
obtain or make, or assume any responsibility for obtaining or making, any
independent evaluation or appraisal of the properties, assets or liabilities,
contingent or otherwise, of WebMD or Healtheon, nor was BancBoston Robertson
Stephens furnished with any such evaluation or appraisal. With respect to the
financial forecasts and projections, and the assumptions and bases therefor, for
each of WebMD and Healtheon that BancBoston Robertson Stephens has reviewed,
upon the advice of the managements of WebMD and Healtheon, BancBoston Robertson
Stephens has assumed that:

     - such forecasts and projections have been reasonably prepared in good
       faith on the basis of reasonable assumptions; and

     - such forecasts and projections reflect the best currently available
       estimates and judgments as to the future financial condition and
       performance of WebMD and Healtheon.

     BancBoston Robertson Stephens has assumed that;

     - the Healtheon-WebMD reorganization will be consummated upon the terms set
       forth in the reorganization agreement without material alteration;

     - the Healtheon-WebMD reorganization will be accounted for as a business
       combination and will be accounted for using the "purchase method" of
       accounting in accordance with generally accepted accounting principles,
       or GAAP;

     - the Healtheon-WebMD reorganization will be treated as a transaction in
       which no gain or loss will be recognized for U.S. federal income tax
       purposes;

     - the historical financial statements of each of WebMD and Healtheon
       reviewed by BancBoston Robertson Stephens have been prepared and fairly
       presented in accordance with GAAP consistently applied; and

     BancBoston Robertson Stephens has relied as to all legal matters relevant
to rendering its opinion on the advice of its counsel. Although developments
following the date of the BancBoston Robertson Stephens opinion may affect the
opinion, BancBoston Robertson Stephens assumed no obligation to update, revise
or reaffirm its opinion. The opinion is necessarily based upon market, economic
and other conditions as in effect on, and information made available to
BancBoston Robertson Stephens as of the date of the opinion. It should be
understood that subsequent developments may affect the conclusion expressed in
the opinion and that BancBoston Robertson Stephens has disclaimed any
undertaking or obligation to advise any person of any change in any matter
affecting the opinion which may come or be brought to BancBoston Robertson
Stephens' attention after the date of the opinion. BancBoston Robertson
Stephens' opinion is limited to the fairness, from a financial point of view and
as of the date thereof, to the holders of WebMD stock, with the exception of
Healtheon, any affiliate of Healtheon and any holder of WebMD Common Stock who
has exercised dissenters' rights, of the exchange ratio.

     BancBoston Robertson Stephens does not express any opinion as to:

     - the value of any employee agreement or other arrangement entered into in
       connection with the WebMD merger;

     - any tax or other consequences that might result from the WebMD merger; or

     - what the value of Healtheon/WebMD common stock will be when issued to
       WebMD's stockholders pursuant to the WebMD merger or the price at which

       the WebMD merger may be traded in the future.

     The following is a summary of the material financial analysis performed by
BancBoston Robertson Stephens in connection with rendering the BancBoston
Robertson Stephens opinion. The summary of the financial analysis is not a
complete description of all of the analyses performed by BancBoston Robertson
Stephens. Certain of the information in this section is presented in a tabular
form. In order to better understand the financial analysis by BancBoston
Robertson Stephens, these tables must be read together with the text of each
summary. The BancBoston Robertson Stephens opinion is based upon the totality of
the various analyses performed by BancBoston Robertson Stephens and no
particular portion of the analyses has any merit standing alone.

     Comparable Company Analysis -- Multiples. BancBoston Robertson Stephens
applied estimated multiples for WebMD with total capitalization to estimated
revenues for calendar years 1999 and 2000. The estimated multiples for WebMD
were based on multiples of the above companies. These estimated multiples
resulted in the following mean implied equity values, implied mean prices per

publicly traded companies involved in internet businesses:

     - America Online

     - @Home

     Precedent Transaction Analysis. Using publicly available information,
BancBoston Robertson Stephens analyzed the consideration offered plus net debt
assumed, debt less cash on hand, and implied transaction value multiples paid or
proposed to be paid in selected merger or acquisition transactions in the
internet content and service industry including:

     - Broadcast.com/Yahoo! (April 1, 1999)

     - Geocities/Yahoo! (January 28, 1999)

     - Excite/@Home (January 19, 1999)

     - Netscape/America Online (November 24, 1998)

     - N2K/CDnow (October 22, 1998)

     - CKS Group, Inc./USWeb Corporation (September 2, 1998)

     - Infoseek/Disney (June 18, 1998)

     BancBoston Robertson Stephens compared, among other things, the total
consideration in the above precedent transactions as a multiple of estimated
revenues of the acquired company for calendar year 2000, for the twelve months
prior to the transaction announcement and for the twelve months subsequent to
the transaction announcement. BancBoston Robertson Stephens applied a range of
multiples based on the above transactions for calendar years 1999 and 2000 from
15.0x to 35.0x and from 10.0x to 25.0x, respectively, and estimated mean
multiples for WebMD for the same periods of 25.0x and 12.5x, respectively. These
mean multiples yielded an implied price per share and an implied exchange ratio
for these periods of $37.81 and 0.471x and of $52.13 and 0.650x, respectively.

     Using publicly available information, BancBoston Robertson Stephens applied
the premiums paid in the precedent transactions to the closing stock price of
the target one day prior to announcement and four weeks prior to announcement
premiums of 35% to 95%, respectively, to the value of WebMD implied by the price
offered by Microsoft in its tender offer for 27.8% of the outstanding stock of
WebMD of $2,100 million.

     Pro Forma Earnings Analysis. BancBoston Robertson Stephens analyzed pro
forma effects resulting from the WebMD merger, including, among other things,
the impact of the WebMD merger on the projected revenues and earnings per share
of the combined company for calendar year 2000. Without taking into account
synergies that the combined company may or may not realize in its operations,
the results of the pro forma earnings analysis suggested that while the WebMD
merger could be 20.3% dilutive to the combined company's revenue per share, the
WebMD merger could be 50.9% accretive to the combined company's cash earnings
per share in calendar year 2000. The actual results achieved by the combined
company may vary from projected results and the variations may be material.

     Contribution Analysis. BancBoston Robertson Stephens estimated that WebMD's
contribution to revenues for calendar years 1998, 1999 and 2000 would imply an
exchange ratio of, 0.022x, 0.560x and 1.307x, respectively, indicating that the
deal exchange ratio of 1.815x represents a 815%, 229% and 38% premiums,
respectively.

     No company, business or transaction compared in the comparable companies
analysis or precedent transaction analysis is identical to WebMD, Healtheon or
the combined company. Accordingly, an analysis of the results of the foregoing
is not entirely mathematical; rather it involves complex considerations and
judgments concerning differences in financial and operating characteristics and
other factors that could affect the acquisition, public trading and other values
of the comparable companies, precedent transactions or the business segment,
company or transactions to which they are being compared.

     While the foregoing summary describes analyses and factors that BancBoston
Robertson Stephens deemed material in its presentation to the WebMD board, it is
not a comprehensive description of all analyses and factors considered by
BancBoston Robertson Stephens. The preparation of a fairness opinion is a
complex process that involves various determinations as to the most appropriate
and relevant methods of financial analysis and the application of these methods
to the particular circumstances and, therefore,

                                       66
<PAGE>   77

such an opinion is not readily susceptible to summary description. BancBoston
Robertson Stephens believes that its analyses must be considered as a whole and
that selecting portions of its analyses and of the factors considered by it,
without considering all analyses and factors, would create an incomplete view of
the evaluation process underlying the BancBoston Robertson Stephens opinion.
Several analytical methodologies were employed and no one method of analysis
should be regarded as critical to the overall conclusion reached by BancBoston
Robertson Stephens. Each analytical technique has inherent strengths and
weaknesses, and the nature of the available information may further affect the
value of particular techniques. The conclusions reached by BancBoston Robertson
Stephens are based on all analyses and factors taken as a whole and also on
application of BancBoston Robertson Stephens own experience and judgment. Such
conclusions may involve significant elements of subjective judgment and
qualitative analysis. BancBoston Robertson Stephens therefore gives no opinion
as to the value or merit standing alone of any one or more parts of the analyses
it performed. In performing its analyses, BancBoston Robertson Stephens
considered general economic, market and financial conditions and other matters,
many of which are beyond the control of WebMD and Healtheon. The analyses
performed by BancBoston Robertson Stephens are not necessarily indicative of
actual values or future results, which may be significantly more or less
favorable than those suggested by such analyses. Accordingly, analyses relating
to the value of a business do not purport to be appraisals or to reflect the
prices at which the business actually may be purchased. Furthermore, no opinion
is being expressed as to the prices at which shares of Healtheon common stock
may be traded at any future time.

     Fees and Indemnification. The BancBoston Robertson Stephens engagement
letter provides that, for its services, BancBoston Robertson Stephens is
entitled to receive a transaction fee of up to a maximum of $15,000,000,
dependent on the outcome of the assignment and the aggregate transaction value
at closing, which includes a $500,000 opinion fee paid upon delivery of the
BancBoston Robertson Stephens opinion. WebMD has also agreed to reimburse
BancBoston Robertson Stephens for limited out-of-pocket expenses, including
legal fees, and to indemnify and hold harmless BancBoston Robertson Stephens and
its affiliates and any person, director, employee or agent of BancBoston
Robertson Stephens or any of its affiliates, or any person controlling
BancBoston Robertson Stephens or its affiliates for losses, claims, damages,
expenses and liabilities relating to or arising out of services provided by
BancBoston Robertson Stephens as financial advisor to WebMD. The terms of the
fee arrangement with BancBoston Robertson Stephens, which WebMD and BancBoston
Robertson Stephens believe are customary in transactions of this nature, were
negotiated at arm's length between WebMD and BancBoston Robertson Stephens, and
the WebMD board was aware of such fee arrangements, including the fact that a
significant portion of the fees payable to BancBoston Robertson Stephens is
contingent upon completion of the WebMD merger. BancBoston Robertson Stephens
and its affiliates have provided financial advisory and financing services for
WebMD, including other advisory work relating to the investment in WebMD by
Microsoft, and advisory work relating to other strategic minority investments,
including those by SOFTBANK Corporation, Intel Corporation, Covad
Communications, Inc., Excite, Inc., and Superior Consultant Holdings
Corporation, for which BancBoston Robertson Stephens will receive fees of
approximately $15,000,000.

     BancBoston Robertson Stephens was retained based on BancBoston Robertson
Stephens' experience as a financial advisor in connection with mergers and
acquisitions and in securities valuations generally, as well as BancBoston
Robertson Stephens' investment banking relationship and familiarity with WebMD.

     BancBoston Robertson Stephens is a nationally recognized investment banking
firm. As part of its investment banking business, BancBoston Robertson Stephens
is frequently engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of securities, private placements and other purposes. BancBoston
Robertson Stephens may actively trade the equity securities of Healtheon for its
own account and for the account of its customers and, accordingly, may at any
time hold a long or short position in such securities.

MODIFICATION OF VESTING OF EMPLOYEE STOCK OPTIONS

     Under their employment or option agreements, options to acquire 923,067
shares of WebMD common stock held by Jeffery T. Arnold, 138,460 shares held by
John Danaher, WebMD's chief medical officer,
                                       67
<PAGE>   78

and 69,867 shares held by three sales and marketing employees that are currently
unvested will vest upon the completion of the reorganization. Mr. Arnold has
agreed and WebMD will request that the other employees agree to modify these
vesting provisions so that the options will not vest upon the completion of the
reorganization but will vest if thereafter the employees are terminated other
than for cause, and in the case of Mr. Arnold, if his duties, responsibilities
or authority is diminished. In addition, Mr. Arnold has agreed and the other
employees will be requested to agree to subject these modified vesting
arrangements to a vote of the stockholders as described above under "The WebMD
Meeting -- votes required; voting agreements; conversion agreements." Absent
these modifications, the options would vest upon the consummation of the
reorganization, but Healtheon/WebMD would be unable to deduct for federal income
tax purposes approximately $28,839,372 of compensation expense, subject to
adjustment based on the actual value of the options on the acceleration date,
attributable to that vesting and the employees would suffer an excise tax of 20%
on such amount.

INTERESTS OF DIRECTORS, OFFICERS AND AFFILIATES IN THE HEALTHEON-WEBMD
REORGANIZATION

     In accordance with the terms of the Healtheon-WebMD reorganization
agreement, four representatives elected by the Board of Directors of WebMD and
four representatives elected by the Board of Directors of Healtheon will become
the initial members of the Board of Directors of Healtheon/WebMD. The
Healtheon/WebMD Board of Directors will be comprised of nine members, with the
other seat to be filled by a person designated by Healtheon and WebMD. It is
expected that Jeffrey T. Arnold, the current Chairman of the Board and Chief
Executive Officer of WebMD, will join the Healtheon/WebMD Board of Directors as
one of the representatives of WebMD and W. Michael Long, the current Chief
Executive Officer of Healtheon, will join the Healtheon/WebMD Board of Directors
as one of the representatives of Healtheon.

     In connection with the Healtheon-WebMD reorganization, Jeffrey T. Arnold
will be offered a position as the Chief Executive Officer of Healtheon/WebMD and
W. Michael Long will be offered a position as the Chairman of the Board and
Chief Operating Officer of Healtheon/WebMD. In addition, Healtheon and WebMD are
currently in the process of negotiating with certain of their executive officers
regarding their potential roles in the combined companies. They are currently
unable to predict the outcome of these discussions. The Healtheon-WebMD
reorganization is not conditioned upon the retention or termination of any of
these officers.

     Mr. Arnold has agreed to waive any vesting of his unvested stock options
granted under his employment agreement that would occur upon the completion of
the WebMD merger. However, if he is terminated other than for cause by
Healtheon/WebMD following the Healtheon-WebMD reorganization, then all options
granted to him pursuant to his employment agreement will immediately vest and
become fully exercisable on the date of such termination.

     Microsoft will have the right to require Healtheon/WebMD to register for
resale the Healtheon/WebMD common stock owned by Microsoft. Microsoft and
Healtheon/WebMD have also agreed to expand Microsoft's strategic relationship
with WebMD following the reorganizations to encompass the entire company. For a
more complete description of the Microsoft relationship see the section entitled
"Healtheon/WebMD's strategic alliances with and investments from Microsoft and
other partners" on page 70.

     Premiere Technologies, Inc. and WebMD entered into an amendment to their
co-marketing and integration agreement in connection with obtaining Premiere
Technologies' agreement to vote for the Healtheon-WebMD reorganization agreement
and the WebMD merger. The amendment requires WebMD to use its best efforts to
cause Healtheon/WebMD to honor the rights and obligations under that agreement,
including the exclusivity for telecommunications services. Boland T. Jones is
the President and Chief Executive Officer of Premiere Technologies and a WebMD
board member. William P. Payne is Vice Chairman of Premiere Technologies and
Chairman of one of its subsidiaries. Mr. Payne is also the Vice Chairman of
WebMD.

COMPLETION AND EFFECTIVENESS OF THE HEALTHEON MERGER AND THE WEBMD MERGER

     The WebMD merger will be completed when all of the conditions to completion
of the WebMD merger are satisfied or waived, including approval and adoption of
the Healtheon-WebMD reorganization agreement by the stockholders of WebMD and
Healtheon and approval of the WebMD merger by the stockholders of WebMD and the
Healtheon merger by the stockholders of Healtheon. The WebMD merger will become
effective upon the filing of the certificate of merger with the State of
Georgia. The Healtheon merger will become effective upon the filing of the
certificate of merger with the State of Delaware.

STRUCTURE OF THE HEALTHEON-WEBMD REORGANIZATION, CONVERSION OF WEBMD COMMON
STOCK AND HEALTHEON COMMON STOCK AND TREATMENT OF WEBMD PREFERRED STOCK

     Pursuant to the Healtheon-WebMD reorganization agreement, the WebMD merger
sub will be merged with and into WebMD and the Healtheon merger sub will be
merged with and into Healtheon, the result of which will be that each of WebMD
and Healtheon will be subsidiaries of Healtheon/ WebMD. Healtheon/WebMD will
thereafter be a public company, the shares of which will be traded on the Nasdaq
National Market and will be held by the former common stockholders of Healtheon
and the former common stockholders of WebMD. Accordingly, the business of
Healtheon/WebMD will initially consist primarily of holding the capital stock of
Healtheon and WebMD, and each of WebMD and Healtheon will continue to operate
its current business.

     Upon completion of the Healtheon merger, each outstanding share of
Healtheon common stock will be converted into the right to receive one share of
Healtheon/WebMD common stock. Upon completion of the WebMD merger, each
outstanding share of WebMD common stock will be converted into a right to
receive 1.815 shares of Healtheon/WebMD common stock. No fractional shares of
Healtheon/WebMD common stock will be issued pursuant to the WebMD merger. In
lieu of the issuance of any fractional shares of Healtheon/WebMD common stock,
cash equal to the product of such fractional share amount and the average
closing sale price of Healtheon common stock on Nasdaq for the ten trading days
prior to the closing date of the mergers will be paid to holders in respect of
any fractional share of Healtheon/ WebMD common stock that would otherwise be
issuable.

     As a result of conversion or voting agreements that have been signed by the
holders of a majority of the outstanding shares of WebMD's Series C, D, E and F
preferred stock, those Series of preferred stock will be converted into WebMD
common stock prior to the effective time of the WebMD merger and will therefore
receive 1.815 shares of Healtheon-WebMD common stock for each share of WebMD
common stock received upon the conversion. In the case of the Series A preferred
stock and Series B preferred stock, if a majority of the holders of either
Series elects to convert into common stock prior to the WebMD merger then the
entire Series is automatically converted. In the case of the Series A preferred
stock, but not the Series B preferred stock, any holder may elect to convert
into common stock prior to the WebMD merger.

     Each outstanding share of WebMD preferred stock that is not converted into
WebMD common stock prior to the effective time of the WebMD merger will remain
outstanding in WebMD, which will be a subsidiary of Healtheon/WebMD following
the reorganization and have the same preferences, rights, privileges or powers
of, or restrictions provided for the benefit of, the holders of the preferred
stock. These preferences and rights include:

     - the right to participate on an as-if-converted to WebMD common stock
       basis in any dividends declared by WebMD on its common stock;

     - the right of the holders of the Series A preferred stock to elect a
       director of WebMD;

     - the right to receive in any liquidation of WebMD a portion of the assets
       distributed in liquidation computed as if the preferred stock had been
       converted into WebMD common stock, but in no event less than the price
       originally paid for the stock, plus any declared but unpaid dividends;

                                       69
<PAGE>   80

     - the right to convert their shares of preferred stock into WebMD common
       stock at a conversion rate of one share of common stock for each share of
       preferred stock, subject to adjustments for dilutive issuances of stock
       by WebMD; and

     - the right to approve stock redemptions, other than under employee stock
       ownership or option plans, the creation of senior equity securities, or
       changes to WebMD bylaws or articles of incorporation or other action that
       would alter the preferences, rights, privileges or powers of, or
       restrictions for the benefit of, the holders of the preferred stock. In
       addition, the holders of the Series A preferred stock would be required
       to approve the creation of any equity securities unless the rights of the
       equity securities to dividends, distributions, and in liquidation were
       junior to the rights of the Series A preferred stock.

The dividend and liquidation rights of the Series A preferred stock are senior
to the rights of the Series B preferred stock.

     In addition to these rights of the holders of the Series A preferred stock
and Series B preferred stock, McKessonHBOC, a holder of Series A and Series B
preferred stock, has additional rights, including:

     - the right to receive annual budgets and business plans of WebMD, subject
       to confidentiality obligations;

     - a right of first refusal to purchase WebMD's physician-only answering
       service business if WebMD desires to sell it;

     - a right of first refusal to purchase equity securities that WebMD may
       sell in the future, other than to the public or in connection with
       acquisitions; and

     - the right to require WebMD to register its securities in WebMD for sale
       to the public in an underwritten public offering.

HEALTHEON/WEBMD'S STRATEGIC ALLIANCES WITH AND INVESTMENTS FROM MICROSOFT AND
OTHER PARTNERS

     As of May 6, 1999, WebMD and Microsoft entered into a strategic alliance,
which is subject to renewal, under which:

     - WebMD will develop, host and maintain a health channel for MSN, MSNBC and
       WebTV and WebMD and Microsoft will share revenues generated by the health
       channel;

     - Microsoft will sponsor up to 5.0 million subscriber/months of WebMD
       subscriptions;

     - WebMD will make Microsoft technology its primary technology platform for
       the health channel and WebMD's Web site;

     - Microsoft and its affiliates will be sole providers of some Internet
       services and content to WebMD;

     - WebMD and Microsoft have committed co-marketing funds and advertising
       space on their respective Web sites; and

     - WebMD and Microsoft share revenues derived from WebMD subscriptions
       sponsored by Microsoft and DuPont.

     The strategic alliance agreement provides that for a five year period,
WebMD will develop, host and maintain a health channel that Microsoft will offer
as a link from the MSN.com home page, and Microsoft will promote the health
channel on the MSN web site in a manner equivalent to all other major MSN topic
specific offerings, and provide a guaranteed minimum amount of advertising for
the health channel. Microsoft has also agreed to promote the WebMD brand by
providing a joint credit on each page of the health channel provided.

     On June 11, 1999 Microsoft completed the purchase of 273,214 shares of
WebMD Series F preferred stock tendered by its stockholders pursuant to an offer
to purchase which was commenced on April 10,
                                       70
<PAGE>   81

1999. In addition, Microsoft purchased from WebMD in May 184,604 shares of
Series E preferred stock for $100 million representing an effective price of
$54.17 per WebMD common share and was issued a warrant to acquire 7,614,916
shares of WebMD common stock at $54.17 per share. On May 20, 1999, Microsoft
committed to acquire another 276,906 shares of Series E preferred stock upon the
completion of the Healtheon-WebMD reorganization for $150 million representing
an effective price of $54.17 per WebMD common share. Microsoft will beneficially
own approximately 17.2% of the outstanding Healtheon/WebMD common stock
following the completion of the reorganizations.

     Healtheon, Microsoft and WebMD have agreed to expand the strategic
relationship to Healtheon/WebMD following the Healtheon-WebMD reorganization.
Healtheon/WebMD has agreed to make the Microsoft technology platform its primary
technology platform.

     In connection with the Microsoft investment, Intel Corporation, Excite
@Home Inc., Covad Communications Group, Inc., SOFTBANK America, Inc., Superior
Consultant Holdings Corporation, The Reader's Digest Association, Inc. and Dell
USA, L.P., an investment vehicle for Dell Computer Corporation, purchased a
total of 276,906 shares of WebMD Series E preferred stock and 184,604 shares of
WebMD Series D common stock for $160 million. These investors have also entered
into strategic relationships with WebMD regarding various aspects of online and
media distribution. For a complete description of these relationships, see the
section entitled "Information Regarding WebMD -- Strategic Relationships."

     Because of these purchases, McKessonHBOC has the right to purchase 38,773
shares of Series E preferred stock, 16,745 shares of Series D common stock, and
a warrant exercisable for 636,980 shares of Series D common stock for an
exercise price of $54.17 per share for aggregate consideration of $21,910,411
representing an effective price per common share of $54.17. Upon the purchase by
Microsoft of an additional 276,906 shares of Series E preferred stock,
McKessonHBOC will have the right to purchase 25,117 shares of Series F preferred
stock for an aggregate price of $13,605,879 representing an effective price per
common share of $54.17. McKessonHBOC will have ten business days after it
receives notice from WebMD describing these rights to exercise these rights.
Assuming McKessonHBOC exercises these rights, it will own approximately 4.5% of
the fully-diluted Healtheon/WebMD common stock following completion of the
reorganizations.

EXCHANGE OF HEALTHEON AND WEBMD STOCK CERTIFICATES FOR HEALTHEON/WEBMD STOCK
CERTIFICATES

     Healtheon stockholders will not exchange their Healtheon stock certificates
for Healtheon/WebMD stock certificates following the reorganization. Each
Healtheon stock certificate will validly evidence an equal number of shares of
Healtheon/WebMD common stock after the merger. DO NOT SUBMIT YOUR HEALTHEON
STOCK CERTIFICATES.

     When the WebMD merger is completed, Healtheon/WebMD's exchange agent will
mail to WebMD stockholders a letter of transmittal and instructions for use in
surrendering WebMD stock certificates in exchange for Healtheon/WebMD stock
certificates. When a WebMD stockholder delivers a WebMD stock certificate to the
exchange agent along with an executed letter of transmittal and any other
required documents, the WebMD stock certificate will be canceled and the WebMD
stockholder will receive Healtheon/WebMD stock certificates representing the
number of full shares of Healtheon/WebMD common stock to which the stockholder
is entitled under the reorganization agreement. A WebMD stockholder will receive
payment in cash, without interest, in lieu of any fractional shares of
Healtheon/ WebMD common stock which would have been otherwise issuable to the
stockholder in the merger.

     WEBMD STOCKHOLDERS SHOULD NOT SUBMIT THEIR WEBMD STOCK CERTIFICATES FOR
EXCHANGE UNTIL THEY RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER OF
TRANSMITTAL FROM THE EXCHANGE AGENT.

                                       71
<PAGE>   82

NO DIVIDENDS

     WebMD stockholders are not entitled to receive any dividends or other
distributions on Healtheon/ WebMD common stock until the Healtheon/WebMD
reorganization is completed and they have surrendered their WebMD stock
certificates in exchange for Healtheon/WebMD stock certificates.

     Subject to the effect of applicable laws, promptly following surrender of
WebMD stock certificates and the issuance of the corresponding Healtheon/WebMD
certificates, WebMD stockholders will be paid the amount of any dividends or
other distributions, without interest, with a record date after the completion
of the reorganization which were previously paid with respect to their whole
shares of Healtheon/WebMD common stock. At the appropriate payment date, WebMD
stockholders will also receive the amount of any dividends or other
distributions, without interest, with a record date after the completion of the
reorganization and a payment date after they exchange their WebMD stock
certificates for Healtheon/WebMD stock certificates.

     Healtheon/WebMD will only issue WebMD stockholders a Healtheon/WebMD stock
certificate or a check in lieu of a fractional share in a name in which the
surrendered WebMD stock certificate is registered. If WebMD stockholders wish to
have their certificates issued in another name they must present the exchange
agent with all documents required to show and effect the unrecorded transfer of
ownership and show that they paid any applicable stock transfer taxes.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE HEALTHEON-WEBMD
REORGANIZATION

     This section summarizes material U.S. federal income tax considerations
relevant to the reorganization that apply to Healtheon/WebMD stockholders. This
discussion is based on existing provisions of the Internal Revenue Code,
existing treasury regulations and current administrative rulings and court
decisions, all of which are subject to change. Any such change, which may or may
not be retroactive, could alter the tax consequences of the merger to you. The
Internal Revenue Service may adopt a contrary position.

     We do not discuss all U.S. federal income tax considerations that may be
relevant to you in light of your particular circumstances. Factors that could
alter the tax consequences of the merger to you include:

     - if you are a dealer in securities;

     - if you are a tax-exempt organization;

     - if you are subject to the alternative minimum tax provisions of the
       Internal Revenue Code;

     - if you are a foreign person or entity;

     - if you are a financial institution or insurance company;

     - if you do not hold your Healtheon or WebMD shares, as the case may be, as
       capital assets;

     - if you acquired your shares in connection with stock option or stock
       purchase plans or in other compensatory transactions;

     - if you hold Healtheon or WebMD shares as part of an integrated
       investment, including a "straddle," comprised of shares of Healtheon or
       WebMD capital stock and one or more other positions; or

     - if you hold Healtheon or WebMD shares subject to the constructive sale
       provisions of Section 1259 of the Internal Revenue Code.

     In addition, we do not discuss the tax consequences of the merger under
foreign, state or local tax laws, the tax consequences of transactions
effectuated prior or subsequent to, or concurrently with, the merger, whether or
not any such transactions are undertaken in connection with the merger,
including without limitation any transaction in which Healtheon or WebMD shares
are acquired or shares of Healtheon/WebMD common stock are disposed of, or the
tax consequences to holders of options, warrants or similar rights to acquire
Healtheon or WebMD capital stock. ACCORDINGLY, WE URGE YOU TO CONSULT YOUR

THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF THE
MERGER.

Tax implications for Healtheon and Healtheon stockholders

     Counsel to Healtheon, Wilson Sonsini Goodrich & Rosati, is of the opinion
that the merger of Healtheon with a wholly owned subsidiary of Healtheon/WebMD
will be a "reorganization" for U.S. federal income tax purposes within the
meaning of section 368(a) of the tax code. This means that, subject to the
limitations and qualifications described below in this section:

     - Healtheon stockholders will not recognize gain or loss when they receive
       Healtheon/WebMD common stock solely in exchange for their shares of
       Healtheon common stock in the Healtheon merger;

     - The aggregate tax basis of the Healtheon/WebMD common stock received by
       holders of Healtheon common stock will be the same as the aggregate tax
       basis of the Healtheon common stock surrendered in the exchange;

     - The holding period of the Healtheon/WebMD common stock received by
       holders of Healtheon common stock in the Healtheon merger will include
       the period the exchanged Healtheon common stock was considered to be
       held, provided that the Healtheon common stock surrendered is held as a
       capital asset at the time of the Healtheon merger; and

     - Healtheon will not recognize gain solely as a result of the Healtheon
       merger.

Tax implications for WebMD and WebMD stockholders

     Counsel to WebMD, Nelson Mullins Riley & Scarborough, L.L.P., is of the
opinion that the merger of WebMD with a wholly owned subsidiary of
Healtheon/WebMD will be a "reorganization" for U.S. federal income tax purposes
within the meaning of section 368(a) of the tax code and/or, when taken together
with the merger of Healtheon with a wholly owned subsidiary of Healtheon/WebMD,
as a transfer of property to Healtheon/WebMD by the shareholders of WebMD
governed by Section 351 of the tax code. This means that, subject to the
limitations and qualifications described below in this section:

     - WebMD stockholders will not recognize gain or loss when they receive
       Healtheon/WebMD common stock solely in exchange for their shares of WebMD
       common stock in the WebMD merger, except for cash received for a
       fractional share of Healtheon/WebMD common stock;

     - Cash payments received by you for a fractional share of Healtheon/WebMD
       common stock should be treated as if such fractional share had been
       issued in the WebMD merger and then redeemed by Healtheon/WebMD. The
       WebMD stockholders should recognize gain or loss with respect to such
       cash payment, measured by the difference, if any, between the amount of
       cash received and the basis in such fractional share;

     - The aggregate tax basis of the Healtheon/WebMD common stock received by
       holders of WebMD common stock will be the same as the aggregate tax basis
       of the WebMD common stock surrendered in exchange for the Healtheon/WebMD
       common stock;

     - The holding period of the Healtheon/WebMD common stock received by
       holders of WebMD stock in the WebMD merger will include the period the
       exchanged WebMD common stock was considered to be held, provided that the
       WebMD common stock surrendered is held as a capital asset at the time of
       the WebMD merger; and

     - WebMD will not recognize gain solely as a result of the WebMD merger.

Limitations on the tax opinions

     Neither Healtheon nor WebMD has requested a ruling from the IRS with regard
to any of the federal income tax consequences of the Healtheon-WebMD Merger.

                                       73
<PAGE>   84

     The opinions described above do not bind the IRS nor preclude it from
adopting a contrary position. These opinions are subject to qualifications and
are conditioned upon assumptions.

Consequences of a contrary IRS determination

     A successful IRS challenge to the reorganization status of the Healtheon
merger would result in a Healtheon stockholder recognizing gain or loss with
respect to each share of Healtheon common stock surrendered. A successful IRS
challenge to the status of the WebMD merger as both a reorganization and, when
taken together with the Healtheon merger, as a transfer of property to
Healtheon/WebMD by the shareholders of WebMD governed by Section 351 of the tax
code, would result in a WebMD stockholder recognizing gain or loss with respect
to each share of WebMD common stock surrendered. In either case, this gain or
loss would equal the difference between the stockholder's basis in the shares
and the fair market value, at the time of the Healtheon-WebMD reorganization, of
the Healtheon/WebMD common stock received. In this event, a stockholder's
aggregate basis in the Healtheon/WebMD common stock received would equal its
fair market value, and the stockholder's holding period for the Healtheon/ WebMD
stock would begin the day after the reorganization.

     Even if the Healtheon merger and the WebMD merger qualify as a
reorganization or as a transaction governed by section 351 of the tax code, a
stockholder who receives shares of Healtheon/WebMD common stock would recognize
gain to the extent that those shares were considered received in exchange for
services. Gain would also have to be recognized to the extent that a holder of
Healtheon common stock or WebMD stock was treated as receiving, directly or
indirectly, consideration other than Healtheon/ WebMD common stock in exchange
for the holder's Healtheon common stock or WebMD common stock. All or a portion
of those gain amounts may be taxable as ordinary income.

ACCOUNTING TREATMENT OF THE HEALTHEON-WEBMD REORGANIZATION

     We intend to account for the Healtheon-WebMD reorganization as a purchase
for financial reporting and accounting purposes, under generally accepted
accounting principles. After the merger, the results of operations of Healtheon
and WebMD will be included in the consolidated financial statements of
Healtheon/WebMD. The purchase price will be allocated based on the fair values
of the assets acquired and the liabilities assumed. Any excess of cost over fair
value of the net tangible assets of WebMD acquired will be recorded as goodwill
and other intangible assets and will be amortized by charges to operations under
generally accepted accounting principles. These allocations will be made based
upon valuations and other studies that have not yet been finalized.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE HEALTHEON-WEBMD
REORGANIZATION

     The merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act, which prevents 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 the
appropriate waiting periods end or expire. Healtheon, WebMD and related parties
will file the required information and materials with the Department of Justice
and the Federal Trade Commission. The requirements of Hart-Scott-Rodino will be
satisfied if the reorganization is completed within one year from the
termination of the waiting period.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the merger on antitrust grounds either before or after
expiration of the waiting period. Accordingly, at any time before or after the
completion of the merger, either the Antitrust Division of the Department of
Justice or the Federal Trade Commission could take action under the antitrust
laws. Other persons could take action under the antitrust laws, including
seeking to enjoin the reorganization. Additionally, at any time before or after
the completion of the merger, notwithstanding that the applicable waiting period
expired or ended, any state could take action under the antitrust laws. A
challenge to the reorganization could be made and we may not prevail.

                                       74
<PAGE>   85

     We are not aware of any other material governmental or regulatory approval
required for completion of the merger, other than the effectiveness of the
registration statement of which this proxy statement/prospectus is a part, and
compliance with applicable corporate laws of Delaware and Georgia.

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF WEBMD AND HEALTHEON

     The shares of Healtheon/WebMD common stock to be issued in the merger will
be registered under the Securities Act. These shares will be freely transferable
under the Securities Act, except for shares of Healtheon/WebMD common stock
issued to any person who is an affiliate of either of WebMD or Healtheon.
Persons who may be deemed to be affiliates include individuals or entities that
control, are controlled by, or are under common control of either of WebMD or
Healtheon and may include some of their respective officers and directors, as
well as their respective principal stockholders. Affiliates may not sell their
shares of Healtheon/WebMD common stock acquired in the merger except pursuant to
(1) an effective registration statement under the Securities Act covering the
resale of those shares, (2) an exemption under paragraph (d) of Rule 145 under
the Securities Act or (3) any other applicable exemption under the Securities
Act.

LISTING ON THE NASDAQ NATIONAL MARKET OF HEALTHEON/WEBMD COMMON STOCK TO BE
ISSUED IN HEALTHEON-WEBMD REORGANIZATION

     It is a condition to the closing of the merger that the shares of
Healtheon/WebMD common stock to be issued in the merger be approved for listing
on Nasdaq, subject to official notice of issuance.

RIGHTS OF DISSENTING WEBMD STOCKHOLDERS

     Pursuant to Sections 14-2-1301 through 14-2-1332, inclusive, of the Georgia
Business Corporation Code, a dissenting WebMD stockholder who desires to object
to the WebMD merger and to receive the fair value of his or her WebMD stock in
cash by following the procedure described below may do so by complying with the
provisions of Georgia law pertaining to the exercise of dissenters' rights. Only
those WebMD stockholders entitled to vote on the reorganization agreement and
WebMD merger are entitled to dissent and receive the fair value of their shares.
As more fully discussed in the section entitled "The WebMD meeting -- required
vote; voting agreements; conversion agreements" only the holders of WebMD common
stock and Series A preferred stock are entitled to vote on the reorganization
and WebMD merger and thus only those holders may dissent and receive the fair
value of their shares. Holders of preferred stock, other than Series A preferred
stock, who wish to dissent to the WebMD merger and obtain the fair value of
their shares must convert their preferred shares into common shares before the
record date for the WebMD stockholders meeting. The following is a summary of
the provisions of Georgia law and is qualified in its entirety by reference to
such provisions, a copy of which is attached as Annex F hereto.

     Georgia law provides that any WebMD stockholder who has the right to vote
on the WebMD merger and who desires to object to the WebMD merger and receive
payment in cash for the fair value of his shares of WebMD stock must deliver,
prior to the WebMD stockholder vote, written notice of his intent to demand
payment of the fair value of his shares if the WebMD merger is effectuated. The
notice must be delivered to WebMD, Inc., 400 The Lenox Building, 3399 Peachtree
Road, NE, Atlanta, Georgia 30326, Attention: W. Michael Heekin, Corporate
Secretary. Further, the dissenting stockholder must not vote his or her shares
in favor of the reorganization agreement or the WebMD merger. The written
objection requirement referred to above will not be satisfied under Georgia law
by merely voting against the reorganization agreement by proxy or in person at
the WebMD meeting. Any holder of WebMD stock who returns a signed proxy but
fails to provide instructions as to the manner in which the shares are to be
voted will be deemed to have voted in favor of the transaction and will not be
entitled to assert dissenters' rights.

     If the reorganization agreement and the WebMD merger are approved by the
WebMD stockholders, WebMD is required to send a written dissenters' notice to
each of the dissenting stockholders who filed a written notice of his intent to
dissent and did not vote in favor of the merger. The dissenters' notice must (a)
state where the dissenting stockholders' first payment demand must be sent and
where and when

                                       75
<PAGE>   86

certificates for certificated shares must be deposited, (b) inform the holders
of uncertificated shares to what extent transfer of such shares will be
restricted after payment demand is made, (c) state the date by which WebMD must
receive the first payment demand, which date shall be fixed by WebMD and shall
not be fewer than 30 nor more than 60 days after the date the dissenters' notice
is delivered, and (d) contain a copy of Georgia law relating to dissenters'
rights. Any dissenting stockholder who voted for or consented in writing to the
reorganization agreement shall not be entitled to a dissenters' notice from
WebMD or to receive payment of the fair value of his or her shares of WebMD
stock pursuant to the dissenters' rights provisions of Georgia law. WebMD is
required to send the dissenters' notice to each of the dissenting stockholders
no later than ten days after the date on which the WebMD stockholders vote to
approve the reorganization agreement. The dissenters' notice will be sent to
each dissenting stockholder at his or her address as it appears in the stock
transfer books of WebMD or at any other address the dissenting stockholder
supplies by notice to WebMD.

     Each dissenting stockholder to whom WebMD sends a dissenter's notice must
make a first payment demand for his or her shares by written notice to WebMD and
deposit his or her share certificates in accordance with the terms of the
dissenters' notice. The first payment demand must contain the name and address
of the dissenting stockholder, the number of shares as to which the dissenting
stockholder is demanding payment and a demand for payment to the dissenting
stockholder of the fair value of his or her shares. Any dissenting stockholder
who does not submit a first payment demand or deposit their shares as set forth
in the dissenters' notice shall lose their rights to dissent and shall not be
entitled to payment for his or her shares pursuant to the dissenters' rights
provisions of Georgia law.

     Within ten days of the later of the closing the WebMD merger or WebMD's
receipt of the first payment demand, WebMD shall offer to pay the dissenting
stockholders who have complied with the provisions of Georgia law the amount
WebMD estimates to be the fair value of the shares plus accrued interest.
WebMD's offer of payment must be accompanied by (a) WebMD's balance sheet as of
the fiscal year ended not more than 16 months before the date of payment, an
income statement for that year, a statement of changes in stockholders' equity
for that year and the latest available interim financial statements, if any; (b)
a statement of WebMD's estimate of the fair value of the shares; (c) an
explanation of how the interest was calculated; (d) a statement of the
dissenting stockholder's right to demand payment of a different amount if the
dissenting stockholder is dissatisfied with the offer; and (e) a copy of Article
13 of Georgia law. If a dissenting stockholder accepts WebMD's offer by
providing written notice to WebMD within 30 days after the date the offer is
made or is deemed to have accepted such offer by failure to respond within said
30 days, WebMD shall make payment for the dissenting stockholder's shares within
60 days after the date WebMD made the offer or the date on which the WebMD
merger occurs, whichever date is later.

     If the WebMD merger is not effected within 60 days after the first payment
demand and the deposit of share certificates, WebMD must return the deposited
share certificates and release the transfer restrictions imposed on
uncertificated shares. If, after such return and release, the WebMD merger is
effectuated, WebMD must send a new dissenters' notice and repeat the payment
demand procedure described above.

     If a dissenting stockholder is dissatisfied with WebMD's offer of payment
or the merger does not occur and WebMD does not return the deposited
certificates within 60 days after the date set for making the first payment
demand, a dissenting stockholder may make a second payment demand to WebMD in
writing of his or her own estimate of the fair value of his or her shares and
the amount of interest due. A dissenting stockholder waives his or her right to
demand payment of a different amount than that offered by WebMD and is deemed to
have accepted the amount offered by WebMD unless the dissenting stockholder
makes a second payment demand within 30 days after the date WebMD makes its
offer.

     In the event a dissenting stockholder's second payment demand remains
unsettled within 60 days after WebMD receives the dissenting stockholder's
second payment demand, WebMD shall commence a nonjury equitable valuation
proceeding in the Superior Court of Fulton County, Georgia to determine the fair
value of the shares and accrued interest. WebMD shall make all dissenting
stockholders whose second payment demand remains unsettled parties to the court
proceeding. In the proceeding, the court will fix a value of the shares and may
appoint one or more appraisers to receive evidence and recommend a decision

                                       76
<PAGE>   87

on the question of fair value. If WebMD does not commence the proceeding within
60 days after receiving the dissenting stockholder's second payment demand,
WebMD shall pay each dissenting stockholder whose second payment demand remains
unsettled the amount demanded by each dissenting stockholder in his or her
second payment demand.

     The determination of a "fair value" necessarily involves matters of
judgment upon which reasonable persons may disagree. Georgia law provides that,
for purposes of dissenters' rights, the value of the WebMD stock is determined
immediately before the consummation of the WebMD merger and that the fair value
excludes any appreciation or depreciation in anticipation of the WebMD merger.

     Any dissenting stockholder who perfects his or her right to be paid the
value of his or her shares will recognize taxable gain or loss upon receipt of
cash for the shares for U.S. federal income tax purposes. For a more complete
description of the federal income tax consequences of the WebMD merger, see the
section entitled "Material U.S. Federal Income Tax Consequences of the
Healtheon -- WebMD reorganization" on page 72.

OPERATIONS AFTER THE HEALTHEON-WEBMD REORGANIZATION

     Following the reorganization, Healtheon and WebMD will continue their
operations as subsidiaries of Healtheon/WebMD. The common stockholders of
Healtheon and WebMD will become stockholders of Healtheon/WebMD, and their
rights as stockholders will be governed by Healtheon/WebMD's amended and
restated certificate of incorporation, Healtheon/WebMD's bylaws and the laws of
the State of Delaware. The holders of the Series A preferred stock and Series B
preferred stock of WebMD could remain holders of those series of preferred stock
of the WebMD subsidiary of Healtheon/WebMD following the reorganization unless
those series are converted into WebMD common stock prior to the reorganization.
See "Comparison of rights of holders of WebMD capital stock and Healtheon/WebMD
common stock" on page 126.

                  THE HEALTHEON-WEBMD REORGANIZATION AGREEMENT

     This section of the proxy statement/prospectus describes the
Healtheon-WebMD reorganization agreement. While we believe that the description
covers the material terms of the reorganization agreement, this summary may not
contain all of the information that is important to you. The reorganization
agreement is attached to this proxy statement/prospectus as Annex A and we urge
you to read it carefully.

REPRESENTATIONS AND WARRANTIES

     Healtheon and WebMD each made representations and warranties in the
Healtheon-WebMD reorganization agreement regarding aspects of their respective
businesses, financial condition, structure and other facts pertinent to the
Healtheon-WebMD reorganization, including:

     - capitalization

     - changes in our businesses since December 31, 1998

     - intellectual property used in our businesses

     - fairness opinions received by our financial advisors

     - financial statements

     In addition, WebMD made additional representations and warranties regarding
payments, if any, required to be made by WebMD to employees and directors on
account of the Healtheon-WebMD reorganization.

     The representations and warranties in the Healtheon-WebMD reorganization
agreement are complicated and not easily summarized. You are urged to carefully
read the sections of the agreement entitled "Representations and Warranties of
the Company" and "Representations and Warranties of Healtheon/WebMD and Merger
Sub."

CONDUCT OF BUSINESS BEFORE COMPLETION OF THE HEALTHEON-WEBMD REORGANIZATION

     Healtheon and WebMD each agreed that until the completion of the
Healtheon-WebMD reorganization or unless the other party consents in writing,
each party will use commercially reasonable efforts consistent with past
practices and policies to:

     - preserve intact its present business organization

     - keep available the services of its present executive officers and key
       employees

     - preserve its relationships with customers, suppliers, licensors,
       licensees, and others with which it has business dealings

     We also agreed that until the completion of the reorganization or unless
the other party consents in writing, each party would conduct its business in
compliance with specific restrictions relating to:

     - the issuance and redemption of securities

     - employees and employee benefits and remuneration

     - intellectual property

     - the issuance of dividends or other distributions

     - modification of certificate or articles of incorporation and bylaws,
       except as contemplated by the reorganization

     - the liquidation or restructuring of, or merger involving, Healtheon or
       WebMD

     - the acquisition of assets or other entities

     - the disposition of assets
                                       78
<PAGE>   89

     - the incurrence of indebtedness

     - entering into, material modification or termination of contracts

     - accounting policies and procedures

     - actions that would jeopardize the tax treatment of the merger

     The agreements related to the conduct of each party's business in the
reorganization agreement are complicated and not easily summarized. You are
urged to carefully read the sections of the reorganization agreement entitled
"Conduct prior to the effective time."

NO OTHER NEGOTIATIONS INVOLVING WEBMD

     Until the Healtheon-WebMD reorganization is completed or the reorganization
agreement is terminated, WebMD has agreed not to directly or indirectly take any
of the following actions without the consent of Healtheon:

     - solicit, initiate, encourage or induce any Acquisition Proposal, as
       defined below

     - participate in any discussions or negotiations regarding any Acquisition
       Proposal

     - disclose any non-public information with respect to any Acquisition
       Proposal

     - take any other action to facilitate any inquiries or the making of any
       proposal that constitutes or may reasonably be expected to lead to any
       Acquisition Proposal

     - engage in discussions with any person with respect to any Acquisition
       Proposal

     - approve, endorse or recommend any Acquisition Proposal

     - enter into any letter of intent or similar document or any contract,
       agreement or commitment relating to any Acquisition Transaction, as
       defined below

     WebMD has agreed to promptly inform Healtheon of any Acquisition Proposal,
request for non-public information or inquiry that WebMD believes would lead to
an Acquisition Proposal, including the identity of the person, entity or group
making the Acquisition Proposal, request or inquiry and the material terms of
the Acquisition Proposal, request or inquiry. WebMD has agreed to inform
Healtheon of the status and details of any Acquisition Proposal.

     An Acquisition Proposal is any offer or proposal relating to any
Acquisition Transaction, other than an offer or proposal from Healtheon. An
Acquisition Transaction is any transaction involving any of the following:

     - the acquisition or purchase of more than a 5% interest in the total
       outstanding voting securities of WebMD or any of its subsidiaries

     - any tender offer or exchange offer, that, if consummated, would result in
       any person or group beneficially owning 5% or more of the total
       outstanding voting securities of WebMD

     - any merger, consolidation, business combination or similar transaction
       involving WebMD

     - any sale, lease outside the ordinary course of business, acquisition or
       disposition of more than 5% of the assets of WebMD

     - any liquidation or dissolution of WebMD

TREATMENT OF HEALTHEON AND WEBMD STOCK OPTIONS AND WARRANTS

     Upon completion of the Healtheon-WebMD reorganization, each outstanding
option or warrant to purchase Healtheon and WebMD capital stock, other than
options or warrants to purchase WebMD Series A or B preferred stock, will be
converted, in accordance with its terms, into an option or warrant, as the case
may be, to purchase the number of shares of Healtheon/WebMD common stock equal
to the
                                       79
<PAGE>   90

number of shares of Healtheon or WebMD common stock that could have been
obtained before the Healtheon-WebMD reorganization upon the exercise of each
option or warrant times the applicable exchange ratio, rounded to the nearest
whole share. The exercise price for options and warrants to purchase WebMD
capital stock that are converted into options and warrants for Healtheon/WebMD
common stock will be equal to the exercise price per share of WebMD common stock
subject to the option or warrant before the reorganization divided by the
exchange ratio, rounded to the nearest whole cent.

     Options and warrants for WebMD Series A and B preferred stock, other than
options to acquire Series B preferred stock under the Sapient option plan, will
remain exercisable for WebMD Series A or Series B preferred stock after the
reorganization, unless a majority of the holders of the applicable Series elects
to cause the entire series to be converted into WebMD common stock prior to the
effective time of the WebMD merger, in which case options and warrants to
purchase such series shall by their terms become options and warrants for
Healtheon/WebMD common stock, with the exercise prices adjusted as provided in
the previous paragraph. Upon completion of the reorganization options granted
under the Sapient Health Network option plan to acquire Series B preferred stock
will become exercisable for Healtheon/WebMD common stock and the exercise price
for such options will be adjusted in the manner provided above.

     The other terms of each option and the Healtheon and WebMD option plans
referred to above under which the options were issued will continue to apply in
accordance with their terms. Upon completion of the reorganization, each
outstanding award, including restricted stock, stock equivalents and stock
units, under any employee incentive or benefit plans, programs or arrangements
maintained by Healtheon and WebMD which provide for grants of equity-based
awards will be amended or converted into a similar instrument of
Healtheon/WebMD, with adjustments to preserve their value. The other terms of
each Healtheon and WebMD award, and the plans or agreements under which they
were issued, will continue to apply in accordance with their terms.

     Healtheon/WebMD intends to file a registration statement on Form S-8, if
available, for the shares of Healtheon/WebMD common stock issuable with respect
to options under the Healtheon and WebMD stock option plans and will maintain
the effectiveness of that registration statement for as long as any of the
options remain outstanding.

BOARD OF DIRECTORS AND OFFICERS OF HEALTHEON/WEBMD

     Immediately after the reorganization, Healtheon/WebMD's board of directors,
will consist of nine persons, four of whom will be designated by the Board of
Directors of WebMD, including Jeffrey T. Arnold, four of whom shall have been
designated by the Board of Directors or Healtheon, including W. Michael Long,
and one of whom will be designated by mutual agreement of Healtheon and WebMD.

     After the reorganization, W. Michael Long, the current Chief Executive
Officer of Healtheon, will be offered a position as Chairman of the Board and
Chief Operating Officer of Healtheon/WebMD, and Jeffrey T. Arnold, the current
Chairman and Chief Executive Officer of WebMD, will be offered a position as
Chief Executive Officer of Healtheon/WebMD.

the reorganization agreement and approval of the mergers by Healtheon and/or
WebMD stockholders:

     - by mutual consent of Healtheon and WebMD

     - by Healtheon or WebMD, if the WebMD merger is not completed before
       December 15, 1999 except that the right to terminate the reorganization
       agreement is not available to any party whose action or failure to act
       has been a principal cause of or resulted in the failure of the WebMD
       merger to occur on or before December 15, 1999 and such action or failure
       to act constitutes a material breach of the reorganization agreement

     - by Healtheon or WebMD, if there is any order of a court or governmental

       the right to terminate the reorganization agreement pursuant to this
       provision by Healtheon is not available to Healtheon where the failure to

       Healtheon's representations or warranties are or become untrue so that

obligations or other acts under the reorganization agreement, waive any
inaccuracies in the other's representations and warranties and waive compliance
by the other with any of the agreements or conditions contained in the

                 HEALTHEON/WEBMD RELATED TRANSACTION AGREEMENTS

     This section of the proxy statement/prospectus describes agreements related
to the merger agreement, including the WebMD stockholders' voting and conversion
agreements, the Healtheon stockholders' voting agreement and the Microsoft
stockholder agreement. While we believe that these descriptions cover the
material terms of these agreements, these summaries may not contain all of the
information that is important to you.

WEBMD STOCKHOLDERS' VOTING AGREEMENT AND CONVERSION AGREEMENT

     Some of WebMD's stockholders who are directors, executive officers or
affiliates of WebMD entered into voting agreements with Healtheon and WebMD. The
voting agreements require these WebMD stockholders to vote all of the shares of
WebMD stock owned by them in favor of

     - the WebMD merger;

     - the conversion of WebMD preferred stock into Series D common stock
       immediately prior to and contingent on the WebMD merger;

     - the acceleration of the vesting provisions in certain WebMD options; and

     - against any proposal in opposition to the WebMD merger or other action
       inconsistent with completing the WebMD merger.

     The voting agreements also contain an irrevocable election to convert any
WebMD preferred stock held by the stockholder into WebMD common stock
immediately prior to the WebMD merger.

     Some holders of WebMD Series B, C, D, E and F preferred stock entered into
conversion agreements with Healtheon and WebMD. The conversion agreements
require the preferred stockholders to:

     - vote to amend the terms of the Series B, C, D, E and F preferred stock to
       permit the automatic conversion of each series of preferred stock into
       Series D common stock upon the election by the holders of a majority of
       the outstanding shares of that series; and

     - no sooner than three business days after the mailing of this proxy
       statement/prospectus, to either:

        - execute a voting agreement in the same form as the voting agreement
          described above, or

        - be deemed to have irrevocably elected to convert their preferred stock
          into WebMD common stock effective as of the day immediately prior to
          the record date of the WebMD stockholder meeting.

     The WebMD stockholders who have executed voting agreements or conversion
agreements also agreed not to transfer or encumber their WebMD shares covered by
those agreements. None of the WebMD stockholders were paid any consideration for
entering into the voting agreements or conversion agreements, although WebMD did
enter into a letter of understanding with Premier Technologies, Inc. described
above under the section entitled "Interests of certain directors, officers and
affiliates in the Healtheon-WebMD reorganization" concerning its strategic
relationship with WebMD following the WebMD merger in connection with obtaining
Premier's voting agreement.

     The voting and conversion agreements will terminate upon the earlier to
occur of:

     - the termination of the reorganization agreement in accordance with its
       terms; or

     - the completion of the merger

HEALTHEON STOCKHOLDERS' VOTING AGREEMENT

     Some Healtheon stockholders have entered into a voting agreement with
WebMD. The voting agreement requires these Healtheon stockholders to vote all of
the shares of Healtheon common stock beneficially owned by them in favor of the
merger.

                                       84
<PAGE>   95

     As of the record date, the Healtheon stockholders who entered into the
voting agreement collectively beneficially owned                shares,
including shares issuable upon exercise of warrants, of Healtheon common stock
which represented approximately [               ] shares of the outstanding
Healtheon common stock. None of the Healtheon stockholders who are parties to
the voting agreement were paid additional consideration in connection with
entering into the voting agreement.

     Each Healtheon stockholder who is a party to the voting agreement agreed
not to sell the Healtheon stock and options owned, controlled or acquired,
either directly or indirectly, by that person until the termination of the
voting agreements or the record date without the prior written consent of WebMD.

     The voting agreement will terminate upon the earlier to occur of:

     - the termination of the reorganization agreement in accordance with its
       terms; or

     - the completion of the merger.

MICROSOFT SHAREHOLDER AGREEMENT

     Microsoft has entered into a shareholder agreement with Healtheon. The
shareholder agreement requires that Microsoft vote all of the shares of WebMD
capital stock beneficially owned by it in favor of the reorganization, unless
there are material amendments to the reorganization agreement.

     As of the record date, Microsoft beneficially owned 14,920,467 shares,
including shares issuable upon exercise of warrants, of WebMD capital stock
which represented approximately 34.9% of the outstanding WebMD capital stock.

     Microsoft agreed not to sell the WebMD stock and options owned, controlled
or acquired, either directly or indirectly, by it until the termination of the
stockholder agreement, or the record date without the prior written consent of
Healtheon, unless the transferee executes an irrevocable proxy to vote the
shares being transferred in favor of the reorganization.

     Microsoft further agreed, effective with the reorganization, to irrevocably
waive certain rights, including its rights of anti-dilution, under the Master
Agreement dated as of April 10, 1999 between WebMD and Microsoft, and under
Microsoft's Warrant to purchase shares of common stock of WebMD dated May 12,
1999.

     The stockholder agreement will terminate upon the earliest to occur of:

     - the termination of the reorganization agreement in accordance with its
       terms; or

     - the completion of the reorganization.

                        THE MEDE AMERICA REORGANIZATION

     This section of the proxy statement/prospectus describes certain aspects of
the proposed MEDE AMERICA reorganization, including the reorganization agreement
and related agreements. While we believe that the description covers the
material terms of the MEDE AMERICA reorganization and the related transactions,
this summary may not contain all of the information that is important to you.
You should read this entire document and the other documents we refer to
carefully for a more complete understanding of the reorganization.

BACKGROUND OF THE MEDE AMERICA REORGANIZATION

     On May 3, 1998, MEDE AMERICA filed a registration statement for an initial
public offering of common stock. Shortly thereafter, the MEDE AMERICA board of
directors decided to evaluate the interest of potential buyers in a strategic
combination or other business combination. On June 1, 1998, MEDE AMERICA engaged
Salomon Smith Barney to act as its financial advisor for this purpose. Over the
course of the next several weeks, at the direction of MEDE AMERICA, Salomon
Smith Barney contacted nine potential buyers, including Healtheon, to ascertain
their interest in acquiring MEDE AMERICA. Of the nine companies contacted, one
indicated interest in acquiring MEDE AMERICA for cash consideration in a range
of $140 million to $150 million. The MEDE AMERICA board of directors decided to
reject the proposal and to proceed with an initial public offering.

     On February 1, 1999, the MEDE AMERICA registration statement was declared
effective and MEDE AMERICA sold 5,307,710 shares of its common stock at a price
to the public of $13 per share.

     On February 16, 1999, Thomas Staudt, the President and Chief Executive
Officer of MEDE AMERICA, was approached by Michael Hoover, President of
Healtheon, regarding a possible strategic business combination between the two
companies. Mr. Staudt indicated that there might be some interest in pursuing
the matter, and that he would be willing to meet with Michael Long, Chief
Executive Officer of Healtheon at the upcoming HIMSS Annual conference scheduled
for February 21 - 25, 1999 in Atlanta, Georgia. Immediately following the
conversation with Mr. Hoover, Mr. Staudt consulted with Anthony J. de Nicola, a
director of MEDE AMERICA and a principal of Welsh, Carson, Anderson & Stowe, its
largest stockholder. During their conversation, Messrs. Staudt and de Nicola
decided that the preliminary discussions with Mr. Long should focus on the need
for Healtheon to establish a level of enterprise valuation for MEDE AMERICA that
would result in an increase in stockholder value to MEDE AMERICA stockholders.

     On February 24, 1999, Messrs. Staudt and Long met. Mr. Staudt informed Mr.
Long that if Healtheon were interested in having further conversations, Mr. Long
should meet with MEDE AMERICA's principal stockholders within the subsequent two
weeks in order to extend a proposal.

     On March 9, 1999, Mr. Long and his advisors met with Messrs. Staudt,
Richard Bankosky, MEDE AMERICA'S Chief Financial Officer, MEDE AMERICA directors
de Nicola, Thomas E. McInerney, who is also a principal of Welsh, Carson,
Anderson and Stowe, and Timothy M. Murray, who is also a general partner of
William Blair Capital Partners, and representatives of Salomon Smith Barney and
Warburg Dillon Read LLC, which had also been retained as a financial advisor to
MEDE AMERICA, and discussed the possibility of Healtheon acquiring MEDE AMERICA.
Further discussions with Healtheon were conducted during the third week of
March.

     On April 1, 1999, MEDE AMERICA and Healtheon entered into a confidentiality
agreement.

     From April 6, 1999 through April 9, 1999, representatives of Healtheon and
its legal and financial advisors conducted business and legal due diligence
meetings in Uniondale, New York. On April 9, 1999, Healtheon presented MEDE
AMERICA with a reorganization agreement for the acquisition of MEDE AMERICA by
Healtheon.

     From April 12, 1999 through April 15, 1999, representatives of MEDE
AMERICA, together with their legal and financial advisors, conducted business
and legal due diligence meetings in Santa Clara,

                                       86
<PAGE>   97

California. At the same time, representatives of both parties began negotiating
the terms of the proposed merger agreement. The negotiation included discussions
regarding:

     - the proposed exchange ratios, and related minimum and maximum thresholds
       given possible fluctuations in the price of Healtheon common stock;

     - the scope of representations and warranties to be made by the parties;

     - conditions to consummation of a reorganization;

     - possible post-reorganization employment arrangements with key employees
       of MEDE AMERICA;

     - treatment of MEDE AMERICA stock options;

     - the scope of the "fiduciary out" provisions of the reorganization
       agreement, which would permit the board of directors to respond to
       unsolicited offers under limited circumstances;

     - the circumstances under which the reorganization agreement could be
       terminated by either party; and

     - the request of Healtheon for voting agreements with the major
       stockholders of MEDE AMERICA.

     On April 14, 1999, the MEDE AMERICA board of directors met to discuss the
progress of the transaction. At this meeting, MEDE AMERICA's legal advisors
discussed the board's fiduciary duties in considering a strategic business
combination and strategic alternatives and discussed the terms of the draft
reorganization agreement and related documents. The board authorized Mr. Staudt
and MEDE AMERICA's legal and financial advisors to continue discussions with
Healtheon and the negotiation of the proposed reorganization agreement.

     The MEDE AMERICA board met again on April 16, 1999 to assess the status of
the transaction. At this meeting, MEDE AMERICA's senior management and legal and
financial advisors reviewed (1) the status of negotiations of the proposed
transaction, (2) the results of the due diligence evaluation of Healtheon, (3)
the benefits and risks of the transaction with Healtheon, and (4) the principal
terms of the draft merger agreement and related documents. The board directed
Mr. Staudt and MEDE AMERICA's legal and financial advisors to continue the
negotiations.

     Negotiations of a definitive reorganization agreement and due diligence
continued through the weekend of April 16 - 18, 1999. Morgan Stanley was
formally engaged by Healtheon on April 19, 1999 to provide it financial advisory
services in connection with the MEDE AMERICA reorganization. During the evening
of April 19, 1999, the MEDE AMERICA board met, together with its financial and
legal advisors, to consider various aspects of the Healtheon proposal, including
the exchange ratio of 0.6593 shares of Healtheon common stock for each share of
MEDE AMERICA stock, and the terms of the proposed "collar" arrangement. MEDE
AMERICA's legal counsel summarized the principal terms of the reorganization
agreement and updated the Board on the status of open points in the
negotiations. Salomon Smith Barney reviewed the financial analyses it performed
in connection with its evaluation of the exchange ratio and rendered to the MEDE
AMERICA board an oral opinion, subject to review of definitive documentation and
other customary matters, as to the fairness, from a financial point of view, of
the exchange ratio to the holders of MEDE AMERICA common stock. Thereafter, the
board unanimously approved the transaction, approved the reorganization
agreement and authorized Mr. Staudt to negotiate the remaining issues with
representatives of Healtheon.

     On April 19, 1999, there was a special meeting of the board of directors of
Healtheon which included a discussion of the reorganization agreement and
related transactions. Morgan Stanley discussed its analyses of the merger with
Healtheon, and responded to various questions raised by members of the Healtheon
board of directors regarding its analyses. The Healtheon board of directors
reviewed a draft of the reorganization agreement, the stock option agreement and
related documents. After considering the terms of the proposed transaction, the
Healtheon board of directors determined that the reorganization was fair to
Healtheon and that the proposed reorganization was in the best interests of
Healtheon. The

                                       87
<PAGE>   98

Healtheon board of directors then unanimously approved the reorganization
agreement and exhibits thereto, including the stock option agreement, and the
reorganization.

     On April 20, 1999, the reorganization agreement was executed and a joint
press release was issued prior to the opening of trading on April 21, 1999.

JOINT REASONS FOR THE MEDE AMERICA REORGANIZATION

     MEDE AMERICA's and Healtheon's boards of directors have determined that the
MEDE AMERICA reorganization is in the best interests of the stockholders of
their respective companies. They concluded that the combined company following
the reorganization would have the potential to realize long-term improved
operating and financial results and a stronger competitive position. The boards
of directors believe that the combined company will:

     - expand each company's connected network of customers and partners,
       accelerating our efforts towards achieving critical mass in the
       healthcare industry and strengthening our competitive positions.
       Healtheon/WebMD is expected to offer connectivity and transactions for
       physicians, consumers and healthcare institutions over a network
       consisting of approximately 540 payers, 180,000 physicians, 1,100
       hospitals, 42,000 pharmacies, 10,000 dentists and 200 affiliate partners

     - increase each company's transaction volume

     - position Healtheon/WebMD to migrate MEDE AMERICA's large, installed base
       of prominent healthcare institutions and professionals to Healtheon's
       Internet-based platform and front-end Web connectivity

     - broaden Healtheon/WebMD's offerings of Internet-based financial and
       clinical transactions services, and create enhanced cross-selling
       opportunities

     - facilitate electronic prescriptions among physicians, consumers and
       pharmacies because of our expanded connectivity

     - create a strong combined management team

MEDE AMERICA'S REASONS FOR THE MEDE AMERICA REORGANIZATION

     The board of directors of MEDE AMERICA has determined that the terms of the
merger are fair to, and in the best interests of, MEDE AMERICA and its
stockholders. ACCORDINGLY, THE MEDE AMERICA BOARD RECOMMENDS THAT YOU VOTE FOR
APPROVAL OF THE REORGANIZATION AGREEMENT AND THE MERGER.

     MEDE AMERICA's board consulted with MEDE AMERICA's senior management as
well as its legal counsel, independent accountants and financial advisors in
reaching its decision to approve the MEDE AMERICA reorganization. Among the
factors considered by MEDE AMERICA's board in its deliberations were the
following:

     (1) historical information concerning Healtheon's and MEDE AMERICA's
         respective financial performance, results of operations, assets,
         liabilities, operations, technology, management and competitive
         position, including Healtheon's public reports filed with the SEC;

     (2) MEDE AMERICA's management's view of the financial condition, results of
         operations, assets, liabilities, businesses and prospects of Healtheon
         and its industry after giving effect to the reorganization;

     (3) current market conditions and historical trading information with
         respect to Healtheon's common stock;

     (4) comparable merger transactions; and

     (5) the terms and conditions of the merger agreement taken as a whole.

                                       88
<PAGE>   99

     In reaching its decision, the MEDE AMERICA board identified several
potential benefits of the merger in addition to the joint benefits identified
above, including the following:

     (1) the combination with Healtheon will allow MEDE AMERICA to access
         internet e-commerce technology at a faster pace than could be achieved
         through internal development, enabling MEDE AMERICA to accelerate
         growth in internet transaction volume and related revenues;

     (2) the implied value of the merger consideration on the date of the
         reorganization agreement ($30.14), which represented a premium of
         approximately 37% over the market price of MEDE AMERICA's stock
         immediately before the announcement of the transaction and 132% over
         the price to the public in MEDE AMERICA's IPO, which had occurred two
         months before;

     (3) the opinion of Salomon Smith Barney as to the fairness, from a
         financial point of view, of the exchange ratio to the holders of MEDE
         AMERICA common stock. This opinion is subject to assumptions and
         limitations noted in the opinion and described under "Opinion of MEDE
         AMERICA's financial advisor," and stockholders should carefully read
         both that section and the opinion of Salomon Smith Barney, which is
         attached to this document as Annex E;

     (4) the opportunity afforded to MEDE AMERICA stockholders to participate in
         the potential growth of the combined company following the
         reorganization or to realize their investment in a market that has been
         more active and liquid than the market for MEDE AMERICA stock; and

     (5) the tax-free nature of the merger, which will allow MEDE AMERICA
         stockholders to defer tax on gains until they sell the Healtheon stock
         they receive in the reorganization.

     The MEDE AMERICA board also identified and considered a variety of
potential negative factors in its deliberations concerning the reorganization,
including, but not limited to:

          (1) the risk to MEDE AMERICA's stockholders that the value to be
     received in the reorganization could decline significantly due to potential
     declines in the trading price of Healtheon stock, which has been extremely
     volatile since its IPO;

          (2) the loss of control over the future operations of MEDE AMERICA
     following the reorganization;

          (3) the impact of the loss of MEDE AMERICA's status as an independent
     company on MEDE AMERICA's stockholders, optionholders, employees and
     customers;

          (4) the risk that the potential strategic benefits sought in the MEDE
     AMERICA reorganization might not be realized;

          (5) the possibility that the MEDE AMERICA reorganization might not be
     consummated and the potential adverse effects of the public announcement of
     the MEDE AMERICA reorganization on:

             (a) MEDE AMERICA's sales and operating results;

             (b) MEDE AMERICA's ability to attract and retain key employees; and

             (c) MEDE AMERICA's overall competitive position;

          (6) the risk that, despite the efforts of Healtheon and MEDE AMERICA,
     key technical and management personnel might not remain employees of
     Healtheon/WebMD following the closing of the merger; and

          (7) the transaction costs expected to be incurred in connection with
     the reorganization transactions and the other risks described under "Risk
     Factors" beginning on page 28.

     After due consideration, the MEDE AMERICA board concluded that the risks
associated with the proposed MEDE AMERICA reorganization were outweighed by the
potential benefits of the merger.

     During the process of evaluating the Healtheon offer, the MEDE AMERICA's
board also considered the provisions of the merger agreement that prohibited
solicitation of third-party bids and the acceptance,
                                       89
<PAGE>   100

approval or recommendation of any unsolicited third-party bids. After fully
discussing these matters during its deliberations, the MEDE AMERICA board
determined that the benefits of the Healtheon offer justified these conditions
and proceeded to approve the merger.

     The foregoing discussion of the information and factors considered by the
MEDE AMERICA board is not intended to be exhaustive but is believed to include
all material factors considered by MEDE AMERICA's board. In view of the
complexity and wide variety of information and factors, both positive and
negative, considered by the MEDE AMERICA board, it did not find it practical to
quantify, rank or otherwise assign relative or specific weights to the factors
considered. In addition, the MEDE AMERICA board did not reach any specific
conclusion with respect to each of the factors considered, or any aspect of any
particular factor, but, rather, conducted an overall analysis of the factors
described above, including thorough discussions with MEDE AMERICA's management
and legal, financial and accounting advisors. In considering the factors
described above, individual members of the MEDE AMERICA board may have given
different weight to different factors. The MEDE AMERICA board of directors
considered all these factors as a whole and believed the factors supported its
determination to approve the Healtheon/MEDE AMERICA reorganization. After taking
into consideration all of the factors set forth above, MEDE AMERICA's board
concluded that the Healtheon/MEDE AMERICA reorganization was fair to, and in the
best interests of, MEDE AMERICA and its stockholders and that MEDE AMERICA
should proceed with the MEDE AMERICA reorganization.

RECOMMENDATION OF MEDE AMERICA'S BOARD OF DIRECTORS

     AFTER CAREFULLY EVALUATING THESE FACTORS, BOTH POSITIVE AND NEGATIVE, THE
BOARD OF DIRECTORS OF MEDE AMERICA HAS DETERMINED THAT THE MEDE AMERICA
REORGANIZATION IS IN YOUR BEST INTERESTS AND UNANIMOUSLY RECOMMENDS THAT YOU
VOTE FOR APPROVAL AND ADOPTION OF THE REORGANIZATION AGREEMENT AND APPROVAL OF
THE REORGANIZATION.

     In considering the recommendation of the MEDE AMERICA board of directors
with respect to the MEDE AMERICA reorganization, you should be aware that
certain directors and officers of MEDE AMERICA have interests in the
reorganization that are different from, or are in addition to the interests of
MEDE AMERICA stockholders generally. Please see the section entitled "Interests
of certain persons in the MEDE AMERICA reorganization" on page 95.

OPINION OF MEDE AMERICA'S FINANCIAL ADVISOR

     Salomon Smith Barney was retained by MEDE AMERICA to act as its financial
advisor in connection with the proposed reorganization. In connection with its
engagement, MEDE AMERICA requested that Salomon Smith Barney evaluate the
fairness, from a financial point of view, to the holders of MEDE AMERICA common
stock of the exchange ratio provided for in the merger. On April 19, 1999, at a
meeting of the MEDE AMERICA board held to evaluate the proposed reorganization,
Salomon Smith Barney delivered to the MEDE AMERICA board an oral opinion,
subsequently confirmed by delivery of a written opinion dated April 20, 1999,
the date of the reorganization agreement, to the effect that, as of the date of
the written opinion and based upon and subject to the matters stated in the
opinion, the exchange ratio was fair, from a financial point of view, to the
holders of MEDE AMERICA common stock.

     In arriving at its opinion, Salomon Smith Barney:

     - reviewed the merger agreement;

     - held discussions with senior officers, directors and other
       representatives and advisors of MEDE AMERICA and senior officers and
       other representatives and advisors of Healtheon concerning the
       businesses, operations and prospects of MEDE AMERICA and Healtheon;

     - examined publicly available business and financial information relating
       to MEDE AMERICA and Healtheon as well as financial forecasts and other
       information and data for MEDE AMERICA and Healtheon which were provided
       to or otherwise discussed with Salomon Smith Barney by the
                                       90
<PAGE>   101

       managements of MEDE AMERICA and Healtheon, including information relating
       to strategic implications and operational benefits anticipated to result
       from the reorganization;

     - reviewed the financial terms of the merger as described in the merger
       agreement in relation to, among other things, current and historical
       market prices and trading volumes of MEDE AMERICA common stock and
       Healtheon common stock, the historical and projected earnings and other
       operating data of MEDE AMERICA and Healtheon, and the capitalization and
       financial condition of MEDE AMERICA and Healtheon;

     - considered, to the extent publicly available, the financial terms of
       other transactions recently effected which Salomon Smith Barney
       considered relevant in evaluating the reorganization;

     - analyzed financial, stock market and other publicly available information
       relating to the businesses of other companies whose operations Salomon
       Smith Barney considered relevant in evaluating those of MEDE AMERICA and
       Healtheon;

     - evaluated the potential pro forma financial impact of the reorganization
       on Healtheon; and

     - conducted other analyses and examinations and considered other financial,
       economic and market criteria as Salomon Smith Barney deemed appropriate
       in arriving at its opinion.

     In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney. With respect to these
financial forecasts and other information and data, the managements of MEDE
AMERICA and Healtheon advised Salomon Smith Barney that they were reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the managements of MEDE AMERICA and Healtheon as to the future
financial performance of MEDE AMERICA and Healtheon and the strategic
implications and operational benefits anticipated to result from the
reorganization.

     Salomon Smith Barney assumed, with the consent of MEDE AMERICA, that the
reorganization will be treated as a "tax-free" reorganization for federal income
tax purposes. Salomon Smith Barney's opinion relates to the relative values of
MEDE AMERICA and Healtheon. Salomon Smith Barney did not express any opinion as
to what the value of Healtheon common stock actually will be when issued to MEDE
AMERICA stockholders pursuant to the reorganization or the prices at which the
Healtheon common stock will trade subsequent to the merger. Salomon Smith Barney
did not make and was not provided with an independent evaluation or appraisal of
the assets or liabilities, contingent or otherwise, of MEDE AMERICA or Healtheon
nor did Salomon Smith Barney make any physical inspection of the properties or
assets of MEDE AMERICA or Healtheon.

     In connection with its opinion, Salomon Smith Barney was not requested to,
and did not, solicit third party indications of interest in the possible
acquisition of all or a part of MEDE AMERICA; however, Salomon Smith Barney, at
the request of MEDE AMERICA, did solicit third party indications of interest in
the possible acquisition of MEDE AMERICA prior to MEDE AMERICA's initial public
offering in February 1999. Salomon Smith Barney expressed no view as to, and its
opinion does not address, the relative merits of the reorganization as compared
to any alternative business strategies that might exist for MEDE AMERICA or the
effect of any other transaction in which MEDE AMERICA might engage. Salomon
Smith Barney's opinion was necessarily based upon information available, and
financial, stock market and other conditions and circumstances existing and
disclosed, to Salomon Smith Barney as of the date of its opinion. Although
Salomon Smith Barney evaluated the exchange ratio from a financial point of
view, Salomon Smith Barney was not asked to and did not recommend the specific
consideration payable in the reorganization, which was determined through
negotiation between MEDE AMERICA and Healtheon. No other instructions or
limitations were imposed by MEDE AMERICA on Salomon Smith Barney with respect to
the investigations made or procedures followed by Salomon Smith Barney in
rendering its opinion.

familiarity with MEDE AMERICA and its business. Salomon Smith Barney regularly
engages in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.

     THE FULL TEXT OF SALOMON SMITH BARNEY'S WRITTEN OPINION DATED APRIL 20,
1999, WHICH DESCRIBES THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS
ON THE REVIEW UNDERTAKEN, IS ATTACHED TO THIS DOCUMENT AS ANNEX E AND SHOULD BE
READ CAREFULLY IN ITS ENTIRETY. SALOMON SMITH BARNEY'S OPINION IS DIRECTED TO
THE MEDE AMERICA BOARD AND RELATES ONLY TO THE FAIRNESS OF THE EXCHANGE RATIO
FROM A FINANCIAL POINT OF VIEW, DOES NOT ADDRESS ANY OTHER ASPECT OF THE
REORGANIZATION OR ANY RELATED TRANSACTION AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY STOCKHOLDER WITH RESPECT TO ANY MATTER RELATING TO THE
PROPOSED REORGANIZATION. THE SUMMARY OF SALOMON SMITH BARNEY'S OPINION INCLUDED
IN THIS DOCUMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF
THE OPINION.

     In preparing its opinion, Salomon Smith Barney performed a variety of
financial and comparative analyses, including those described below. The summary
of these analyses is not a complete description of the analyses underlying
Salomon Smith Barney's opinion. The preparation of a fairness opinion is a
complex analytic process involving various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances and, therefore, a fairness opinion
is not readily susceptible to summary description. Accordingly, Salomon Smith
Barney believes that its analyses must be considered as a whole and that
selecting portions of its analyses and factors or focusing on information
presented in tabular format, without considering all analyses and factors or the
narrative description of the analyses, could create a misleading or incomplete
view of the processes underlying its analyses and opinion. The order in which
Salomon Smith Barney's analyses are described, and the results derived from its
analyses, do not represent the relative weight or importance given to the
analyses by Salomon Smith Barney.

     In its analyses, Salomon Smith Barney considered industry performance,
general business, economic, market and financial conditions and other matters
existing on or about April 20, 1999, many of which are beyond the control of
MEDE AMERICA and Healtheon. No company, transaction or business used in those
analyses as a comparison is identical to MEDE AMERICA, Healtheon or the proposed
reorganization, nor is an evaluation of those analyses entirely mathematical;
rather, the analyses involve complex considerations and judgments concerning
financial and operating characteristics and other factors that could affect the
reorganization, public trading or other values of the companies, business
segments or transactions being analyzed. The estimates contained in Salomon
Smith Barney's analyses and the valuation ranges resulting from any particular
analysis are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than those
suggested by its analyses. In addition, analyses relating to the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which businesses or securities actually may be sold. Accordingly,
Salomon Smith Barney's analyses and estimates are inherently subject to
substantial uncertainty.

     Salomon Smith Barney's opinion and analyses were only one of many factors
considered by the MEDE AMERICA board in its evaluation of the merger and should
not be viewed as determinative of the views of the MEDE AMERICA board or
management with respect to the exchange ratio or the proposed reorganization.

     The following is a summary of the material financial analyses performed by
Salomon Smith Barney in connection with the rendering of its opinion. CERTAIN OF
THE FINANCIAL ANALYSES SUMMARIZED BELOW INCLUDE INFORMATION PRESENTED IN TABULAR
FORMAT. IN ORDER TO FULLY UNDERSTAND SALOMON SMITH BARNEY'S FINANCIAL ANALYSES,
THE TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE
DO NOT CONSTITUTE A COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES. CONSIDERING
THE DATA SET FORTH BELOW WITHOUT CONSIDERING THE FULL NARRATIVE DESCRIPTION OF

<PAGE>   103

ASSUMPTIONS UNDERLYING THE ANALYSES, COULD CREATE A MISLEADING OR INCOMPLETE
VIEW OF SALOMON SMITH BARNEY'S FINANCIAL ANALYSES.

MEDE AMERICA Public Market Analysis

     Salomon Smith Barney derived an implied equity reference range for MEDE
AMERICA by performing a public market analysis. A public market analysis
provides a valuation range based, among other things, on the trading multiples
of a group of publicly traded peer companies. Salomon Smith Barney compared
financial information of MEDE AMERICA with similar information for the following
two groups of publicly traded companies:

     Healthcare Electronic Data Interchange Companies

     - MedQuist Inc.
     - National Data Corporation
     - QuadraMed Corporation

     Other Electronic Data Interchange Companies

     - Harbinger Corp.
     - QRS Corporation
     - Sterling Commerce, Inc.

     Salomon Smith Barney compared, among other things, market prices as a
multiple of estimated calendar years 1999 and 2000 earnings per share, adjusted
for after-tax amortization related to purchase accounting, and firm value,
calculated as equity value, plus debt, less cash, as a multiple of estimated
calendar year 1999 earnings before interest, taxes, depreciation and
amortization, commonly known as EBITDA. All multiples were based on closing
stock prices on April 20, 1999. Estimated financial data for the selected
companies were based on publicly available research analysts' estimates and
estimated financial data for MEDE AMERICA were based on internal estimates of
the management of MEDE AMERICA.

     Applying a range of selected multiples of estimated calendar years 1999 and
2000 adjusted earnings per share and estimated calendar year 1999 EBITDA for the
selected companies to corresponding financial data of MEDE AMERICA resulted in
an implied reference range for MEDE AMERICA of approximately $16.28 to $20.24
per share, as compared to the equity value implied by the exchange ratio of
approximately $30.14 per share based on the closing stock price of Healtheon
common stock on April 20, 1999.

Precedent Transactions Analysis

     Salomon Smith Barney derived an implied per share equity reference range
for MEDE AMERICA by performing a precedent transactions analysis. A precedent
transaction analysis provides a valuation range based, among other things, on
the purchase prices paid in transactions involving peer companies in the same or
similar industries as the company or business segment analyzed. Using publicly
available information, Salomon Smith Barney reviewed the purchase prices and
implied transaction value multiples paid or proposed to be paid in the following
seven selected transactions:

</TABLE>

                                       93
<PAGE>   104

     Salomon Smith Barney compared the firm values implied by the purchase
prices in the selected transactions as multiples of, among other things, latest
12 months revenues and EBITDA. All multiples were based on financial information
available at the announcement date of the relevant transaction.

     Applying a range of selected multiples for the selected transactions of
latest 12 months revenues and EBITDA to calendar year 1998 revenues and calendar
years 1998 and 1999 EBITDA of MEDE AMERICA resulted in an implied reference
range for MEDE AMERICA of approximately $21.88 to $27.48 per share, as compared
to the equity value implied by the exchange ratio of approximately $30.14 per
share based on the closing stock price of Healtheon common stock on April 20,
1999.

Discounted Cash Flow Analysis

     Salomon Smith Barney derived an implied per share equity reference range
for MEDE AMERICA by performing a five-year discounted cash flow analysis, based
on internal estimates of the management of MEDE AMERICA, on the stand-alone
unlevered free cash flows of MEDE AMERICA. A discounted cash flow analysis
determines the net present value of the projected free cash flows of a company
or business segment. The range of estimated terminal values for MEDE AMERICA was
calculated by applying terminal value multiples of 11.0x to 15.0x, with
particular focus on terminal value multiples of 12.0x to 14.0x, to the projected
2003 EBITDA of MEDE AMERICA. The cash flows and terminal values were discounted
to present value using discount rates ranging from 12% to 14%, with particular
focus on discount rates of 12.5% to 13.5%.

     Based on terminal multiples of 12.0x to 14.0x and discount rates of 12.5%
to 13.5%, this analysis resulted in an implied per share equity reference range
for MEDE AMERICA of approximately $23.24 to $27.06 per share, as compared to the
equity value implied by the exchange ratio of approximately $30.14 per share
based on the closing stock price of Healtheon common stock on April 20, 1999.

Premiums Analysis

     Salomon Smith Barney analyzed the premiums implied by the exchange ratio in
the reorganization based on the closing stock price of Healtheon common stock on
April 20, 1999 and based on the closing stock prices of MEDE AMERICA common
stock on the date of its initial public offering, over the 10 day trading period
ending April 20, 1999. This analysis indicated the following implied premiums:

Historical Exchange Ratio Analysis

     Salomon Smith Barney reviewed the relationship between the daily closing
prices of MEDE AMERICA common stock and Healtheon common stock during the period
beginning on the date of Healtheon's initial public offering on February 11,
1999 through April 20, 1999 and the implied historical exchange ratios
determined by dividing the price per share of MEDE AMERICA common stock by the
price per share of Healtheon common stock over that period. The following
compares the exchange ratio in the reorganization with the high, low and average
of such historical exchange ratios:

Pro Forma Earnings Per Share Impact on Healtheon

     Salomon Smith Barney analyzed the potential pro forma financial effects of
the reorganization on, among other things, Healtheon's earnings per share for
calendar years 1999 and 2000, based on internal estimates of the managements of
MEDE AMERICA and Healtheon and without giving effect to potential synergies that
may result from the merger. The results of the pro forma merger analysis
suggested that the merger could be dilutive to, or result in a decrease in,
Healtheon's earnings per share in calendar years 1999 and 2000. The actual
results achieved by the combined company may vary from projected results and the
variations may be material.

Miscellaneous

     Pursuant to the terms of its engagement, MEDE AMERICA has agreed to pay
Salomon Smith Barney upon completion of the reorganization an aggregate
financial advisory fee equal to 0.7% of the aggregate consideration, including
liabilities assumed, payable in connection with the merger. MEDE AMERICA has
also agreed to reimburse Salomon Smith Barney for travel and other out-of-pocket
expenses incurred by Salomon Smith Barney in performing its services, including
the fees and expenses of its legal counsel, and to indemnify Salomon Smith
Barney and related persons against liabilities, including liabilities under the
federal securities laws, arising out of its engagement.

     Salomon Smith Barney has advised MEDE AMERICA that, in the ordinary course
of business, Salomon Smith Barney and its affiliates may actively trade or hold
the securities of MEDE AMERICA and Healtheon for their own account or for the
account of customers and, accordingly, may at any time hold a long or short
position in those securities. Salomon Smith Barney has in the past provided
investment banking services to MEDE AMERICA unrelated to the proposed
reorganization, for which services Salomon Smith Barney has received
compensation. In addition, Salomon Smith Barney and its affiliates, including
Citigroup Inc. and its affiliates, may maintain relationships with MEDE AMERICA,
Healtheon and their respective affiliates.

INTERESTS OF CERTAIN PERSONS IN THE MEDE AMERICA REORGANIZATION

     When considering the recommendation of MEDE AMERICA's board of directors,
MEDE AMERICA stockholders should be aware that some of the directors and
officers of MEDE AMERICA have interests in the reorganization and have
arrangements that are different from, or are in addition to those of MEDE
AMERICA stockholders generally. These include:

     - Board of Directors. Welsh, Carson, Anderson & Stowe and William Blair &
       Co., L.L.C., two significant stockholders of MEDE AMERICA, will have the
       right to select one nominee to the board of directors of Healtheon.
       Thomas E. McInerney and Anthony J. de Nicola, directors of MEDE AMERICA,
       are general partners of WCAS. Timothy M. Murray, a director of MEDE
       AMERICA, is a principal of William Blair & Co.

     - Registration Rights. Welsh, Carson, Anderson & Stowe and William Blair &
       Co., L.L.C. will have the right to require Healtheon/WebMD to register
       for resale up to 6,000,000 of the shares of Healtheon/WebMD common stock
       that they receive as a result of the reorganization.

     - Stock Option Grants. Employees of MEDE AMERICA will receive options to
       purchase an aggregate of 700,000 shares of Healtheon/WebMD common stock,
       with an exercise price of $45.72 per share, following the completion of
       the reorganization, to be allocated individually at a later date. The
       options will vest over four years, and are intended to serve as
       compensation for continued service to Healtheon/WebMD.

     - Potential Vesting of Options. In the event that employees of MEDE AMERICA
       have their employment terminated without cause or are constructively
       terminated by Healtheon/WebMD within two years after the completion of
       the reorganization, any options that were held by those employees prior
       to the completion of the reorganization will vest fully.

                                       95
<PAGE>   106

     - Vesting of Warrants. Medic Computer Systems, Inc. holds a warrant to
       purchase 1,250,000 shares of MEDE AMERICA common stock that would vest at
       the time the merger is completed. One of the members of the MEDE AMERICA
       board of directors, Alan Winchester, sits as a designee of Medic.

     - Transaction Fee. If the MEDE AMERICA reorganization is completed, William
       Blair & Co., L.L.C. will receive a transaction fee of 0.05% of the MEDE
       AMERICA reorganization transaction value, which is based on the closing
       price of the Healtheon common stock for the five trading days preceding
       the closing.

     - Indemnification. Healtheon and MEDE AMERICA directors have customary
       rights to indemnification.

     As a result, these directors could be more likely to vote to approve the
reorganization agreement and the reorganization than if they did not hold these
interests.

COMPLETION AND EFFECTIVENESS OF THE MEDE AMERICA REORGANIZATION

     The reorganization will be completed when all of the conditions to
completion of the reorganization are satisfied or waived, including approval and
adoption of the reorganization agreement and approval of the merger by the
stockholders of MEDE AMERICA. The merger will become effective upon the filing
of a certificate of merger with the State of Delaware.

STRUCTURE OF THE MEDE AMERICA REORGANIZATION AND CONVERSION OF MEDE AMERICA
COMMON STOCK

     Merc Acquisition Corp., a newly formed and wholly owned subsidiary of
Healtheon/WebMD, will be merged with and into MEDE AMERICA. As a result of the
merger, the separate corporate existence of Merc will cease and MEDE AMERICA
will survive the reorganization as a wholly owned subsidiary of Healtheon/WebMD.

     Upon completion of the reorganization, each outstanding share of MEDE
AMERICA common stock will be automatically canceled and converted into the right
to receive a specific number of shares of Healtheon/WebMD common stock. The
number of shares of Healtheon/WebMD common stock that will be issued in exchange
for each outstanding share of MEDE AMERICA common stock is referred to as the
exchange ratio. The exchange ratio in the reorganization will depend upon the
average closing price of Healtheon common stock as reported on Nasdaq for the
ten trading day periods ending on July 30, 1999 and ending two days before the
date of the MEDE AMERICA stockholder meeting.

     - If the lower average closing sale price of Healtheon common stock for
       such periods is between $38.68 and $63.70, the exchange ratio in the
       reorganization will be 0.6593.

     - If the average closing price of Healtheon common stock is less than
       $38.68 for the period ending July 30, 1999, Healtheon may adjust the
       exchange ratio within the next 24 hour period, to equal the quotient
       obtained by dividing $25.50 by such average price. If the average closing
       sale price of Healtheon common stock for the ten day period ending two
       days before the special meeting is less than the average price for the
       July 30 period, Healtheon may elect to further adjust the exchange ratio
       no later than 24 hours prior to the MEDE AMERICA stockholder meeting, to
       equal the quotient obtained by dividing $25.50 by such lower average
       price.

     - If the average price for the July 30 period is equal to or greater than
       $38.68, but the average closing sale price for the ten day period ending
       two days prior to the special meeting is less than $38.68, Healtheon may
       adjust the exchange ratio no later than 24 hours prior to the MEDE
       AMERICA stockholders meeting to equal the quotient obtained by dividing
       $25.50 by such lower average sale price.

     - If the lower average closing sale price of Healtheon common stock is
       greater than $63.70, for the ten consecutive trading day periods, MEDE
       AMERICA may adjust the exchange ratio no later than
                                       96
<PAGE>   107

       24 hours prior to the MEDE AMERICA stockholder meeting, to equal the
       quotient obtained by dividing $42.00 by such lower average price.

     The exchange ratio will also be adjusted to reflect the effect of any stock
split, reverse stock split, stock dividend, reorganization, recapitalization,
reclassification or other like change with respect to Healtheon common stock or
MEDE AMERICA common stock occurring prior to the completion of the
reorganization.

     No certificate or scrip representing fractional shares of Healtheon/WebMD
common stock will be issued in connection with the merger. Instead MEDE AMERICA
stockholders will receive cash, without interest, in lieu of a fraction of a
share of Healtheon/WebMD common stock.

EXCHANGE OF MEDE AMERICA STOCK CERTIFICATES FOR HEALTHEON/WEBMD STOCK
CERTIFICATES

     When the reorganization is completed, Healtheon/WebMD's exchange agent will
mail to MEDE AMERICA stockholders a letter of transmittal and instructions for
use in surrendering MEDE AMERICA stock certificates in exchange for
Healtheon/WebMD stock certificates. When MEDE AMERICA stockholders deliver their
MEDE AMERICA stock certificates to the exchange agent along with an executed
letter of transmittal and any other required documents, their MEDE AMERICA stock
certificates will be canceled and MEDE AMERICA stockholders will receive
Healtheon/WebMD stock certificates. MEDE AMERICA stockholders will receive
payment in cash, without interest, in lieu of any fractional shares of
Healtheon/WebMD common stock which would have been otherwise issuable to MEDE
AMERICA stockholders in the reorganization.

     YOU SHOULD NOT SUBMIT YOUR MEDE AMERICA STOCK CERTIFICATES FOR EXCHANGE
UNTIL YOU RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER OF
TRANSMITTAL FROM THE EXCHANGE AGENT.

     MEDE AMERICA stockholders are not entitled to receive any dividends or
other distributions on Healtheon/WebMD common stock until the reorganization is
completed and they have surrendered their MEDE AMERICA stock certificates in
exchange for Healtheon/WebMD stock certificates.

     Subject to the effect of applicable laws, promptly following surrender of
MEDE AMERICA stock certificates and the issuance of the corresponding
Healtheon/WebMD certificates, MEDE AMERICA stockholders will be paid the amount
of any dividends or other distributions, without interest, with a record date
after the completion of the reorganization which were previously paid with
respect to their whole shares of Healtheon/WebMD common stock. At the
appropriate payment date, MEDE AMERICA stockholders will also receive the amount
of any dividends or other distributions, without interest, with a record date
after the completion of the merger and a payment date after they exchange their
MEDE AMERICA stock certificates for Healtheon/WebMD stock certificates.

     Healtheon/WebMD will only issue MEDE AMERICA stockholders a Healtheon/WebMD
stock certificate or a check in lieu of a fractional share in a name in which
the surrendered MEDE AMERICA stock certificate is registered. If you wish to
have your certificate issued in another name you must present the exchange agent
with all documents required to show and effect the unrecorded transfer of
ownership and show that you paid any applicable stock transfer taxes.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE MEDE AMERICA
REORGANIZATION

     This section summarizes material U.S. federal income tax considerations
relevant to the merger that apply to MEDE AMERICA stockholders. This discussion
is based on existing provisions of the Internal Revenue Code, existing treasury
regulations and current administrative rulings and court decisions, all of which
are subject to change. Any such change, which may or may not be retroactive,
could alter the tax consequences of the merger to you. The Internal Revenue
Service may adopt a contrary position.

                                       97
<PAGE>   108

     We do not discuss all U.S. federal income tax considerations that may be
relevant to you in light of your particular circumstances. Factors that could
alter the tax consequences of the merger to you include:

     - if you are a dealer in securities;

     - if you are a tax-exempt organization;

     - if you are subject to the alternative minimum tax provisions of the
       Internal Revenue Code;

     - if you are a foreign person or entity;

     - if you are a financial institution or insurance company;

     - if you do not hold your MEDE AMERICA shares as capital assets;

     - if you acquired your shares in connection with stock option or stock
       purchase plans or in other compensatory transactions;

     - if you hold MEDE AMERICA shares as part of an integrated investment,
       including a "straddle", comprised of shares of MEDE AMERICA common stock
       and one or more other positions; or

     - if you hold MEDE AMERICA shares subject to the constructive sale
       provisions of Section 1259 of the Internal Revenue Code.

     In addition, we do not discuss the tax consequences of the reorganization
under foreign, state or local tax laws, the tax consequences of transactions
effectuated prior or subsequent to, or concurrently with, the reorganization,
whether or not any such transactions are undertaken in connection with the
reorganization, including without limitation any transaction in which MEDE
AMERICA shares are acquired or shares of Healtheon/WebMD common stock are
disposed of, or the tax consequences to holders of options, warrants or similar
rights to acquire MEDE AMERICA capital stock. ACCORDINGLY, WE URGE YOU TO
CONSULT YOUR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE
REORGANIZATION, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES TO YOU OF THE REORGANIZATION.

     Tax implications for MEDE AMERICA and MEDE AMERICA stockholders

     Counsel to Healtheon, Wilson Sonsini Goodrich & Rosati, and counsel to MEDE
AMERICA, Reboul, MacMurray, Hewitt, Maynard & Kristol, are of the opinion that
the merger of MEDE AMERICA with a wholly owned subsidiary of Healtheon/WebMD
will be a "reorganization" for U.S. federal income tax purposes within the
meaning of section 368(a) of the Internal Revenue Code. This means that, subject
to the limitations and qualifications described below in this section:

     - MEDE AMERICA stockholders will not recognize gain or loss when they
       receive Healtheon/ WebMD common stock solely in exchange for their shares
       of MEDE AMERICA common stock in the MEDE AMERICA merger, except on cash
       received for a fractional share of Healtheon/ WebMD common stock;

     - Cash payments received by MEDE AMERICA stockholders for a fractional
       share of Healtheon/ WebMD common stock should be treated as if such
       fractional share had been issued in the merger and then redeemed by
       Healtheon/WebMD. You should recognize gain or loss with respect to such
       cash payment, measured by the difference, if any, between the amount of
       cash received and the basis in such fractional share;

     - The aggregate tax basis of the Healtheon/WebMD common stock received by
       holders of MEDE AMERICA common stock will be the same as the aggregate
       tax basis of the MEDE AMERICA stock surrendered in the exchange;

     - The holding period of the Healtheon/WebMD common stock received by
       holders of MEDE AMERICA stock in the MEDE AMERICA merger will include the
       period the exchanged MEDE AMERICA stock was considered to be held,
       provided that the MEDE AMERICA stock surrendered is held as a capital
       asset at the time of the MEDE AMERICA reorganization; and

                                       98
<PAGE>   109

     - MEDE AMERICA will not recognize gain solely as a result of the MEDE
       AMERICA reorganization.

Limitations on the tax opinions

     MEDE AMERICA has not requested a ruling from the IRS with regard to any of
the federal income tax consequences of the MEDE AMERICA reorganization.

     The opinions described above do not bind the IRS nor preclude it from
adopting a contrary position. These opinions are subject to qualifications and
are conditioned upon assumptions.

Consequences of a contrary IRS determination

     A successful IRS challenge to the reorganization status of the MEDE AMERICA
reorganization would result in a MEDE AMERICA stockholder recognizing gain or
loss with respect to each share of MEDE AMERICA stock surrendered. This gain or
loss would equal the difference between the stockholder's basis in the MEDE
AMERICA share and the fair market value, at the time of the Healtheon-WebMD
reorganization, of the Healtheon/WebMD common stock received. In such event, a
stockholder's aggregate basis in the Healtheon/WebMD common stock received would
equal its fair market value, and the stockholder's holding period for the
Healtheon/WebMD stock would begin the day after the MEDE AMERICA reorganization.

     Even if the MEDE AMERICA reorganization qualifies as a reorganization, a
recipient of shares of Healtheon/WebMD common stock would recognize gain to the
extent that those shares were considered to be received in exchange for
services. Gain would also have to be recognized to the extent that a holder of
MEDE AMERICA stock was treated as receiving, directly or indirectly,
consideration other than Healtheon/WebMD common stock in exchange for the
holder's MEDE AMERICA stock. All or a portion of those gain amounts may be
taxable as ordinary income.

ACCOUNTING TREATMENT OF THE MEDE AMERICA REORGANIZATION

     Healtheon and MEDE AMERICA intend to account for the reorganization as a
purchase for financial reporting and accounting purposes, under generally
accepted accounting principles. After the reorganization, the results of
operations of MEDE AMERICA will be included in the consolidated financial
statements of Healtheon/WebMD. The purchase price will be allocated based on the
fair values of the assets acquired and the liabilities assumed. Any excess of
cost over fair value of the net tangible assets of MEDE AMERICA acquired will be
recorded as goodwill and other intangible assets and will be amortized by
charges to operations under generally accepted accounting principles. These
allocations will be made based upon valuations and other studies that have not
yet been finalized.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE MEDE AMERICA
REORGANIZATION

     The reorganization is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act, which prevents 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 the
appropriate waiting periods end or expire. We have filed the required
information and materials with the Department of Justice and the Federal Trade
Commission and the applicable waiting period has expired. The requirements of
Hart-Scott-Rodino will be satisfied if the merger is completed within one year
from the termination of the waiting period.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the reorganization on antitrust grounds either before
or after expiration of the waiting period. Accordingly, at any time before or
after the completion of the reorganization, either the Antitrust Division of the
Department of Justice or the Federal Trade Commission could take action under
the antitrust laws. Certain other persons could take action under the antitrust
laws, including seeking to enjoin the reorganization. Additionally, at any time
before or after the completion of the reorganization,

                                       99
<PAGE>   110

notwithstanding that the applicable waiting period expired or ended, any state
could take action under the antitrust laws. A challenge to the reorganization
could be made and if a challenge is made we may not prevail.

     Neither Healtheon nor MEDE AMERICA is aware of any other material
governmental or regulatory approval required for completion of the
reorganization, other than the effectiveness of the registration statement of
which this proxy statement/prospectus is a part, and compliance with applicable
corporate law of Delaware.

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF MEDE AMERICA AND HEALTHEON

     The shares of Healtheon/WebMD common stock to be issued in the
reorganization will be registered under the Securities Act. These shares will be
freely transferable under the Securities Act, except for shares of
Healtheon/WebMD common stock issued to any person who is an affiliate of either
Healtheon/ WebMD or MEDE AMERICA. Persons who may be deemed to be affiliates
include individuals or entities that control, are controlled by, or are under
common control of either Healtheon or MEDE AMERICA and may include some of their
respective officers and directors, as well as their respective principal
stockholders. Affiliates may not sell their shares of Healtheon/WebMD common
stock acquired in the reorganization except pursuant to (1) an effective
registration statement under the Securities Act covering the resale of those
shares, (2) an exemption under paragraph (d) of Rule 145 under the Securities
Act or (3) any other applicable exemption under the Securities Act.

LISTING ON THE NASDAQ NATIONAL MARKET OF HEALTHEON COMMON STOCK TO BE ISSUED IN
THE MEDE AMERICA REORGANIZATION

     It is a condition to the closing of the reorganization that the shares of
Healtheon/WebMD common stock to be issued in the reorganization be approved for
listing on the Nasdaq National Market, subject to official notice of issuance.

DELISTING AND DEREGISTRATION OF MEDE AMERICA COMMON STOCK AFTER THE MEDE AMERICA
REORGANIZATION

     If the reorganization is completed, MEDE AMERICA common stock will be
delisted from the Nasdaq National Market and will be deregistered under the
Securities Exchange Act.

OPERATIONS AFTER THE MEDE AMERICA REORGANIZATION

     Following the reorganization, MEDE AMERICA will continue its operations as
a wholly owned subsidiary of Healtheon/WebMD. The stockholders of MEDE AMERICA
will become stockholders of Healtheon/WebMD, and their rights as stockholders
will be governed by the Healtheon/WebMD certificate of incorporation, the
Healtheon/WebMD bylaws and the laws of the State of Delaware. See "Comparison of
rights of holders of MEDE AMERICA common stock and Healtheon/WebMD common stock"
on page 139.

                   THE MEDE AMERICA REORGANIZATION AGREEMENT

     This section of the proxy statement/prospectus describes the MEDE AMERICA
reorganization agreement. While we believe that the description covers the
material terms of the reorganization agreement, this summary may not contain all
of the information that is important to you. The reorganization agreement is
attached to this proxy statement/prospectus as Annex B and we urge you to read
it carefully.

REPRESENTATIONS AND WARRANTIES

     Healtheon and MEDE AMERICA each made representations and warranties in the
reorganization agreement regarding aspects of their businesses, financial
condition, structure and other facts pertinent to the reorganization, including:

     - capitalization

     - changes in our businesses since December 31, 1998

     - intellectual property used in our businesses

     - material contracts

     In addition, MEDE AMERICA made additional representations and warranties
regarding payments, if any, required to be made by MEDE AMERICA to employees and
directors because of the reorganization and the fairness opinion received by
MEDE AMERICA from its financial advisor.

     The representations and warranties in the merger agreement are complicated

     The agreements related to the conduct of MEDE AMERICA's business in the
reorganization agreement are complicated and not easily summarized. You are
urged to carefully read the sections of the reorganization agreement entitled
"Conduct of business by the company."

HEALTHEON'S CONDUCT OF BUSINESS BEFORE COMPLETION OF THE MEDE AMERICA
REORGANIZATION

     Healtheon agreed that until the completion of the reorganization or unless
MEDE AMERICA consents in writing, Healtheon and its subsidiaries would conduct
their business so as not to jeopardize the tax treatment of the reorganization.

NO OTHER NEGOTIATIONS INVOLVING MEDE AMERICA

     Until the reorganization is completed or the reorganization agreement is
terminated, MEDE AMERICA has agreed not to directly or indirectly take any of
the following actions:

     - solicit, initiate, encourage or induce any Acquisition Proposal, as
       defined below

     - participate in any discussions or negotiations regarding any Acquisition
       Proposal

     - disclose any non-public information with respect to any Acquisition
       Proposal

     - take any other action to facilitate any inquiries or the making of any
       proposal that constitutes or may reasonably be expected to lead to any
       Acquisition Proposal

     - engage in discussions with any person with respect to any Acquisition
       Proposal

     - approve, endorse or recommend any Acquisition Proposal

     - enter into any letter of intent or similar document or any contract,
       agreement or commitment relating to any Acquisition Transaction, as
       defined below

     Notwithstanding the limitations on MEDE AMERICA's actions, MEDE AMERICA may
furnish information and engage in negotiations in response to an unsolicited,
bona fide "Superior Offer" made by a third party, provided that MEDE AMERICA's
board has concluded, on the advice of outside counsel, that:

     - such action is necessary to comply with its fiduciary obligations;

     - MEDE AMERICA notifies Healtheon/WebMD beforehand, and enters into a
       confidentiality agreement with such third party having terms no less
       favorable to MEDE AMERICA than those contained in its confidentiality
       agreement with Healtheon/WebMD; and

     - MEDE AMERICA provides any nonpublic information disclosed to the third
       party to Healtheon/WebMD.

     A "Superior Offer" is any of the following transactions which the board of
MEDE AMERICA determines, after consultation with a financial adviser of national
reputation, is more favorable to MEDE AMERICA's stockholders than the MEDE
AMERICA reorganization:

     - any merger or consolidation in which the MEDE AMERICA stockholders before
       the transaction hold less than 50% of the equity interest in the
       surviving entity;

                                       102
<PAGE>   113

     - any sale or other disposition of assets of MEDE AMERICA representing in
       excess of 85% of the fair market value of MEDE AMERICA's business;

     - the acquisition by any person or group of ownership of 85% or more of the
       then outstanding stock of MEDE AMERICA.

     MEDE AMERICA has agreed to promptly inform Healtheon as to any Acquisition
Proposal, request for non-public information or inquiry which MEDE AMERICA
believes would lead to an Acquisition Proposal, including the identity of the
person, entity or group making the Acquisition Proposal, request or inquiry and
the material terms of the Acquisition Proposal, request or inquiry. MEDE AMERICA
has agreed to inform Healtheon of the status and details of any Acquisition
Proposal.

     An ACQUISITION PROPOSAL is any offer or proposal relating to any
Acquisition Transaction, other than an offer or proposal from Healtheon.

     An ACQUISITION TRANSACTION is any transaction involving any of the
following:

     - the acquisition or purchase of more than a 5% interest in the total
       outstanding voting securities of MEDE AMERICA or any of its subsidiaries

     - any tender offer or exchange offer, that, if consummated, would result in
       any person or group beneficially owning 5% or more of the total
       outstanding voting securities of MEDE AMERICA

     - any merger, consolidation, business combination or similar transaction
       involving MEDE AMERICA

     - any sale, lease outside the ordinary course of business, acquisition or
       disposition of more than 5% of the assets of MEDE AMERICA

     - any liquidation or dissolution of MEDE AMERICA

MEDE AMERICA'S EMPLOYEE BENEFIT PLANS

     Individuals who are employed by MEDE AMERICA when the reorganization is
completed will become employees of Healtheon/WebMD or one of its subsidiaries,
although Healtheon/WebMD may terminate these employees at any time.
Healtheon/WebMD and MEDE AMERICA will work together to agree upon mutually
acceptable employee benefit and compensation arrangements so as to provide
benefits to MEDE AMERICA employees generally equivalent in the aggregate to
those provided to similarly situated employees of Healtheon/WebMD. MEDE AMERICA
will terminate its separation, retention and salary continuation plans, programs
or arrangements prior to the effective time of the reorganization.
Healtheon/WebMD has agreed to maintain MEDE AMERICA's employee severance policy
for one year following the reorganization.

TREATMENT OF MEDE AMERICA STOCK OPTIONS AND WARRANTS

     Upon completion of the reorganization, each outstanding option or warrant
to purchase MEDE AMERICA common stock will be converted, in accordance with its
terms, into an option or warrant, as the case may be, to purchase the number of
shares of Healtheon/WebMD common stock equal to the number of shares of MEDE
AMERICA common stock that could have been obtained before the reorganization
upon the exercise of each option or warrant times the exchange ratio, rounded
down to the nearest whole share. The exercise price will be equal to the
exercise price per share of MEDE AMERICA common stock subject to the option or
warrant before conversion divided by the exchange ratio, rounded up to the
nearest whole cent.

     The other terms of each option and the MEDE AMERICA option plans referred
to above under which the options were issued will continue to apply in
accordance with their terms. Upon completion of the reorganization, each
outstanding award, including restricted stock, stock equivalents and stock
units, under any employee incentive or benefit plans, programs or arrangements
maintained by MEDE AMERICA which provide for grants of equity-based awards will
be amended or converted into a similar instrument of Healtheon, with certain
adjustments to preserve their value. The other terms of each MEDE
                                       103
<PAGE>   114

AMERICA award, and the plans or agreements under which they were issued, will
continue to apply in accordance with their terms, except that Healtheon has
agreed to provide for the options of any employees who are terminated without
cause or are constructively terminated within two years following the
reorganization to become fully vested.

     Healtheon/WebMD intends to file a registration statement on Form S-8, if
available, for the shares of Healtheon/WebMD common stock issuable with respect
to options under the MEDE AMERICA stock option plans and will maintain the
effectiveness of that registration statement for as long as any of the options
remain outstanding.

GRANT OF HEALTHEON/WEBMD STOCK OPTIONS

     Healtheon/WebMD agreed to grant options to purchase 700,000 shares at a per
share price of $45.72 to employees of MEDE AMERICA immediately following the
reorganization. These options will be granted in reasonable and customary
amounts sufficient to provide adequate incentive to former MEDE AMERICA
employees in connection with their service on behalf of Healtheon/WebMD.

          correct but the effect in each case, and in the aggregate, of the
          inaccuracies of these representations and breaches of these
          warranties, other than that concerning Healtheon/WebMD's board

TERMINATION OF THE MEDE AMERICA REORGANIZATION AGREEMENT

     The reorganization agreement may be terminated at any time prior to
completion of the reorganization, whether before or after approval and adoption
of the reorganization agreement and approval of the reorganization by MEDE
AMERICA stockholders:

     - by mutual consent of Healtheon/WebMD and MEDE AMERICA

     - by Healtheon/WebMD or MEDE AMERICA, if the reorganization is not
       completed before September 30, 1999 except that the right to terminate
       the reorganization agreement is not available to any party whose action
       or failure to act has been a principal cause of or resulted in the
       failure of the reorganization to occur on or before September 30, 1999
       and such action or failure to act constitutes a material breach of the
       reorganization agreement

                                       105
<PAGE>   116

     - by Healtheon/WebMD or MEDE AMERICA, if there is any order of a court or

     - by Healtheon/WebMD or MEDE AMERICA, if the reorganization agreement fails
       to receive the requisite vote for approval and adoption by the
       stockholders of MEDE AMERICA at the MEDE AMERICA special meeting, except

       provision by MEDE AMERICA is not available to MEDE AMERICA where the
       failure to obtain MEDE AMERICA stockholder approval was caused by the
       action or failure to act by MEDE AMERICA and such action or failure to
       act constitutes a material breach of the reorganization agreement

     - by Healtheon/WebMD, at any time prior to the adoption and approval of the
       reorganization agreement and the reorganization by the required vote of
       MEDE AMERICA stockholders:

        - if MEDE AMERICA's board of directors withdraws or amends or modifies
          in a manner adverse to Healtheon/WebMD its unanimous recommendation in

     - by MEDE AMERICA, upon a breach of any representation, warranty, covenant
       or agreement on the part of Healtheon/WebMD set forth in the
       reorganization agreement, or if any of Healtheon/ WebMD's representations
       or warranties are or become untrue so that the corresponding condition to
       completion of the reorganization would not be met. However, if the breach
       or inaccuracy is curable by Healtheon/WebMD through the exercise of its
       commercially reasonable efforts, and Healtheon/WebMD continues to
       exercise such commercially reasonable efforts, MEDE AMERICA may not

PAYMENT OF TERMINATION FEE

     MEDE AMERICA will pay Healtheon/WebMD a termination fee of $15 million
promptly, but not later than, two days after the reorganization agreement is
terminated by Healtheon/WebMD if:

     - MEDE AMERICA's board of directors withdraws or amends or modifies in a

       tender or exchange offer is first published, sent or given, a statement
       disclosing that MEDE AMERICA recommends rejection of such tender or
       exchange offer

     Also, in the event that the reorganization agreement is terminated by
either Healtheon/WebMD or MEDE AMERICA because (1) the reorganization has not
been consummated by September 30, 1999 or (2) the failure to obtain the required
approval of MEDE AMERICA stockholders, and, in either event, prior to that
termination a third party has publicly announced an Acquisition Proposal, and
within 12 months following that termination, MEDE AMERICA consummates a Company
Acquisition, or enters into an agreement providing for a Company Acquisition,
MEDE AMERICA will pay to Healtheon/WebMD a termination fee of $15 million
promptly, but not later than, two days after the consummation of the Company
Acquisition or the entry by MEDE AMERICA into that agreement.

     A Company Acquisition is any of the following:

     - a merger, consolidation, business combination, recapitalization,
       liquidation, dissolution or similar transaction involving MEDE AMERICA
       pursuant to which the stockholders of MEDE AMERICA immediately preceding
       such transaction hold less than 50% of the aggregate equity interests in
       the surviving or resulting entity of such transaction

     - a sale or other disposition by MEDE AMERICA of assets representing in
       excess of 50% of the aggregate fair market value of MEDE AMERICA's
       business immediately prior to such sale

       offer or an exchange offer or issuance by MEDE AMERICA, directly or
       indirectly, of beneficial ownership or a right to acquire beneficial
       ownership of shares representing in excess of 50% of the voting power of
       the then outstanding shares of capital stock of MEDE AMERICA

EXTENSION, WAIVER AND AMENDMENT OF THE MEDE AMERICA REORGANIZATION AGREEMENT

     We may amend the reorganization agreement before completion of the merger
provided we comply with applicable state law in so doing.

     Either of us may extend the other's time for the performance of any of the
obligations or other acts under the reorganization agreement, waive any
inaccuracies in the other's representations and warranties and waive compliance
by the other with any of the agreements or conditions contained in the
reorganization agreement.

                  MEDE AMERICA RELATED TRANSACTION AGREEMENTS

     This section of the proxy statement/prospectus describes agreements related
to the MEDE AMERICA reorganization agreement, including the MEDE AMERICA
stockholders' voting agreement, and the registration rights agreement. While we
believe that these descriptions cover the material terms of these agreements,
these summaries may not contain all of the information that is important to you.

MEDE AMERICA VOTING AGREEMENT

     Healtheon required MEDE AMERICA stockholders Welsh, Carson, Alexander &
Stowe V, L.P., Welsh, Carson, Anderson & Stowe VI, L.P., WCAS Information
Partners L.P., WCAS Capital Partners II, L.P., William Blair Capital Partners V,
L.P. and William Blair Leveraged Capital Fund, Limited Partnership to enter into
a voting agreement. The voting agreement requires these MEDE AMERICA
stockholders to vote all of the shares of MEDE AMERICA common stock beneficially
owned by them in favor of the reorganization.

     As of the record date, the MEDE AMERICA stockholders who entered into the
voting agreement collectively beneficially owned 6,295,759 shares, which
includes shares issuable upon exercise of warrants, of MEDE AMERICA common stock
which represented approximately 47.4% of the outstanding MEDE AMERICA common
stock. None of the MEDE AMERICA stockholders who are parties to the voting
agreement were paid additional consideration in connection with entering into
the voting agreement.

     Each MEDE AMERICA stockholder who is a party to the voting agreement agreed
not to sell the MEDE AMERICA stock and options owned, controlled or acquired,
either directly or indirectly, by that person until the termination of the
voting agreements or the record date without the prior written consent of
Healtheon.

     The voting agreement will terminate upon the earlier to occur of:

     - the termination of the reorganization agreement in accordance with its
       terms; or

     - the completion of the reorganization.

MEDE AMERICA REGISTRATION RIGHTS AGREEMENT

     Healtheon/WebMD agreed with MEDE AMERICA stockholders Welsh, Carson,
Alexander & Stowe V, L.P., Welsh, Carson, Anderson & Stowe VI, L.P., WCAS
Information Partners L.P., WCAS Capital Partners II, L.P., William Blair Capital
Partners V, L.P. and William Blair Leveraged Capital Fund, Limited Partnership
to enter into a registration rights agreement. The registration rights agreement
gives these MEDE AMERICA stockholders the right to have shares of
Healtheon/WebMD common stock they receive in the merger registered with the
Securities and Exchange Commission. These MEDE AMERICA stockholders currently
hold similar rights with respect to their shares of MEDE AMERICA common stock.

     The MEDE AMERICA stockholders who are parties to the registration rights
agreement are permitted to request that Healtheon/WebMD register up to 3,000,000
shares of Healtheon/WebMD common stock they receive as a result of the
reorganization within three months after the merger and an additional 3,000,000
shares within six months after the reorganization. As of the record date, the
MEDE AMERICA stockholders who entered into the registration rights agreement
collectively beneficially owned 6,295,759 shares, which includes shares issuable
upon exercise of warrants, of MEDE AMERICA common stock which represented
approximately 47.4% of the outstanding MEDE AMERICA common stock.
Healtheon/WebMD is only required to complete two registrations under the
registration rights agreement. Healtheon/WebMD will pay the expenses of these
registrations, subject to certain exceptions. The request for the first of these
registrations must be made within sixty days following the reorganization.

     The following table sets forth the closing prices per share of Healtheon
common stock and MEDE AMERICA common stock as reported on the Nasdaq National
Market on (1) April 20, 1999, the business day preceding public announcement
that Healtheon and MEDE AMERICA had entered into the merger agreement and (2)
[               ], 1999, the last full trading day for which closing prices were
available at the time of the printing of this proxy statement/prospectus. This
table also sets forth the equivalent price per share of MEDE AMERICA common
stock on those dates. The equivalent price per share is equal to the closing
price of a share of Healtheon common stock on that date multiplied by 0.6593,
the number of shares of Healtheon common stock to be issued in exchange for each
share of MEDE AMERICA common stock, assuming no adjustment to the exchange ratio
as provided for in the MEDE AMERICA reorganization agreement.

     MEDE AMERICA and Healtheon believe that MEDE AMERICA common stock presently
trades on the basis of the value of the Healtheon common stock expected to be
issued in exchange for the MEDE AMERICA common stock in the MEDE AMERICA
reorganization, discounted primarily for the uncertainties associated with the
reorganization. Apart from the publicly disclosed information concerning
Healtheon which is included in this proxy statement/prospectus, Healtheon cannot
state with certainty what factors account for changes in the market price of the
Healtheon common stock.

     MEDE AMERICA stockholders are advised to obtain current market quotations
for Healtheon common stock and MEDE AMERICA common stock. No assurance can be
given as to the market prices of Healtheon common stock or MEDE AMERICA common
stock at any time before the consummation of the reorganization or as to the
market price of Healtheon common stock at any time after the reorganization. You
may receive less than or more than 0.6593 of a share of Healtheon/WebMD common
stock for each share of your MEDE AMERICA common stock depending on the lower
average closing sale price of Healtheon common stock for the ten trading day
periods ending on July 30, 1999 and ending two days prior to the stockholders'
meeting. See "Structure of the MEDE AMERICA reorganization and conversion of
MEDE AMERICA common stock" on page 96 of this proxy statement/prospectus for
further information.

     HEALTHEON AND MEDE AMERICA HAVE NEVER PAID CASH DIVIDENDS ON THEIR
RESPECTIVE SHARES OF CAPITAL STOCK. PURSUANT TO THE MEDE AMERICA REORGANIZATION
AGREEMENT, MEDE AMERICA HAS AGREED NOT TO PAY CASH DIVIDENDS PENDING THE
CONSUMMATION OF THE REORGANIZATION, WITHOUT WRITTEN CONSENT OF HEALTHEON/WEBMD.

                              UNAUDITED PRO FORMA
                    CONDENSED COMBINED FINANCIAL INFORMATION

     The following unaudited pro forma condensed combined financial information
for Healtheon/WebMD gives effect to:

     1. The proposed Healtheon-WebMD reorganization and MEDE AMERICA
        reorganization using the purchase accounting method, based on
        preliminary allocations of the total estimated purchase prices. The
        historical financial information has been derived from the respective
        historical financial statements of Healtheon, WebMD and MEDE AMERICA,
        and should be read in conjunction with such financial statements and the
        related notes included in this proxy statement/prospectus.

     2. The proposed Healtheon-WebMD reorganization only, using the purchase
        accounting method, based on a preliminary allocation of the total
        estimated purchase price. The historical financial information has been
        derived from the respective historical financial statements of Healtheon
        and WebMD, and should be read in conjunction with such financial
        statements and the related notes included in this proxy
        statement/prospectus.

     3. The proposed MEDE AMERICA reorganization only, using the purchase
        accounting method, based on a preliminary allocation of the total
        estimated purchase price. The historical financial information has been
        derived from the respective historical financial statements of Healtheon
        and MEDE AMERICA, and should be read in conjunction with such financial
        statements and the related notes included in this proxy
        statement/prospectus.

     The unaudited pro forma condensed combined balance sheets have been
prepared assuming the reorganizations took place as of March 31, 1999 and
allocate the total estimated purchase prices to the fair values of assets and
liabilities of the acquired companies based on preliminary valuations.

     The unaudited pro forma condensed combined statements of operations combine
Healtheon's, WebMD's and MEDE AMERICA's historical statements of operations and
give effect to the reorganizations, including the amortization of goodwill and
other intangible assets resulting from the reorganizations, as if they occurred
on January 1, 1998, for the twelve months ended December 31, 1998 and on January
1, 1999 for the three months ended March 31, 1999. The MEDE AMERICA financial
information has been recast to conform to Healtheon's December 31 fiscal year
end. The unaudited pro forma condensed combined statement of operations for the
year ended December 31, 1998 combines the audited historical consolidated
statement of operations of Healtheon for the year ended December 31, 1998, the
audited historical consolidated statement of operations of WebMD, after giving
effect to the acquisitions of Sapient Health Network, Inc. and Direct Medical
Knowledge, Inc. -- the entities were acquired by WebMD in January 1999, for the
year ended December 31, 1998, and the unaudited historical consolidated
statement of operations of MEDE AMERICA, after giving effect to the acquisition
of Healthcare Interchange, Inc. -- this entity was acquired by MEDE AMERICA in
October 1998, for the twelve months ended December 31, 1998.

     The total estimated purchase prices of WebMD and MEDE AMERICA have been
allocated on a preliminary basis to assets and liabilities based on management's
estimates of their fair values with the excess costs over the net assets
acquired allocated to goodwill and other intangible assets. These allocations
are subject to change pending a final determination and analysis of the total
purchase prices and the fair values of the assets acquired and liabilities
assumed. The impact of such changes could be material.

     The unaudited pro forma condensed combined information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have actually occurred if the
reorganizations, either individually or combined, had been consummated as of the
dates indicated, nor is it necessarily indicative of the future operating
results or financial position of the combined companies. The pro forma
adjustments are based on the information available at the time of the printing
of this proxy statement/prospectus.

                          HEALTHEON/WEBMD CORPORATION

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
           COMBINED WITH WEBMD AND MEDE AMERICA FINANCIAL INFORMATION

     The unaudited pro forma condensed combined financial information reflects
the Healtheon-WebMD reorganization and MEDE AMERICA reorganization and gives
effect to certain reclassifications to the unaudited historical financial
statements to conform the presentation of the historical operations of the
merged companies.

     The total estimated purchase prices of the reorganizations have been
allocated on a preliminary basis to assets and liabilities based on management's
estimate of their fair values. The excess of the purchase prices over the fair
value of the net assets acquired has been allocated to goodwill and other
intangible assets. These allocations are subject to change pending the
completion of the final analysis of the total purchase prices and fair values of
the assets acquired and liabilities assumed. The impact of such changes could be
material.

     The adjustments to the unaudited pro forma condensed combined balance sheet
as of March 31, 1999, have been calculated as if the reorganizations occurred on
March 31, 1999 and are as follows:

     (1) To reflect the acquisition of all of the outstanding capital stock of
         WebMD and MEDE AMERICA by exchanging shares of Healtheon/WebMD common
         stock in exchange for each share of WebMD and MEDE AMERICA capital
         stock for a total estimated combined purchase price of approximately
         $7,196.9 million. The purchase consideration consists of the issuance
         of an estimated 70.6 million shares of Healtheon/WebMD's common stock
         with a fair value of approximately $5,086.8 million and the assumption
         of options and warrants to purchase 13.2 million shares of Healtheon's
         Common Stock with a fair value of approximately $2,035.1 million and
         other related reorganization costs of approximately $75.0 million,
         consisting primarily of approximately $54.5 million in investment
         banking, legal, accounting and regulatory filing fees, and
         approximately $20.5 million in costs anticipated to be incurred for
         employee retention, work force reduction, facility consolidation and
         other reorganization related costs.

        The estimated fair value of the common stock to be issued is based on
        the average closing price of Healtheon's common stock on the five days
        prior and subsequent to the days the reorganizations were announced,
        which was May 20, 1999 for WebMD and April 21, 1999 for MEDE AMERICA.
        The estimated fair value of the options and warrants to be assumed is
        based on the Black-Scholes model using the following assumptions:

        - Expected lives of one-half to 2.5 years

        - Expected volatility factor of 1.0

        - Risk-free interest rate of 4.5%

        - Expected dividend rate of 0%

        The purchase price for MEDE AMERICA may be increased or decreased by 25%
        based upon the lower average closing price of Healtheon's stock for the
        10 day periods ending July 30, 1999 and ending two days prior to the
        special meeting of MEDE AMERICA stockholders, if that lower average
        stock price exceeds $63.70 or is below $38.39.

     (2) Recognition of the excess purchase price of approximately $7,112.7
         million over the fair value of net tangible assets acquired, have been
         recorded as goodwill and other intangible assets.

     (3) To reflect the elimination of the historical stockholders' equity
         accounts of WebMD and MEDE AMERICA.

     (4) To reflect the elimination of goodwill and other intangible assets on
         the balance sheets of WebMD and MEDE AMERICA as of the acquisition
         date.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
     COMBINED WITH WEBMD AND MEDE AMERICA FINANCIAL INFORMATION (CONTINUED)

     (5) To reflect the proceeds, net of offering costs, relating to the
         investments in capital stock made or to be made by strategic partners
         prior to the consummation of the Healtheon-WebMD reorganization. The
         Healtheon-WebMD reorganization agreement requires that these
         investments be completed prior to the closing of the Healtheon-WebMD
         reorganization.

     The adjustments to the unaudited pro forma condensed combined statements of
operations for the quarter ended March 31, 1999 and year ended December 31,
1998, assume the reorganizations occurred as of January 1, 1999 and January 1,
1998 and are as follows:

     (A) To reflect the amortization of goodwill and other intangible assets
         resulting from the reorganizations. The goodwill and other intangible
         assets are being amortized over periods of approximately three to four
         years. Currently, management does not anticipate that any significant
         value will be attributed to purchased in-process research and
         development.

     (B) Basic and diluted net loss per share have been adjusted to reflect the
         issuance of approximately 70.6 million shares of Healtheon/WebMD's
         common stock, as if the shares had been outstanding for the entire
         periods presented. The effect of stock options and warrants of WebMD
         and MEDE AMERICA assumed in the reorganizations have not been included
         as their inclusion would be anti-dilutive.

                          HEALTHEON/WEBMD CORPORATION

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                   COMBINED WITH WEBMD FINANCIAL INFORMATION

     The unaudited pro forma condensed combined financial information reflects
the Healtheon-WebMD reorganization and gives effect to certain reclassifications
to the unaudited historical financial statements to conform the presentation of
the historical operations of the merged companies.

     The total estimated purchase price of the reorganization has been allocated
on a preliminary basis to assets and liabilities based on management's estimate
of their fair values. The excess of the purchase price over the fair value of
the net assets acquired has been allocated to goodwill and other intangible
assets. This allocation is subject to change pending the completion of the final
analysis of the fair value of the assets acquired and liabilities assumed. The
impact of such changes could be material.

     The adjustments to the unaudited pro forma condensed combined balance sheet
as of March 31, 1999, have been calculated as if the reorganization occurred on
March 31, 1999 and are as follows:

     (1) To reflect the acquisition of all of the outstanding capital stock of
         WebMD by exchanging 1.815 shares of Healtheon/WebMD common stock for
         each share of WebMD capital stock for a total estimated purchase price
         of approximately $6,671.6 million. The purchase consideration consists
         of the issuance of an estimated 62.1 million shares of
         Healtheon/WebMD's common stock with a fair value of approximately
         $4,646.4 million and the assumption of options and warrants to purchase
         11.7 million shares of Healtheon/WebMD's common stock with a fair value
         of approximately $1,974.0 million and other related reorganization
         costs of approximately $51.2 million, consisting primarily of
         approximately $42.1 million in investment banking, legal, accounting
         and regulatory filing fees, and approximately $9.1 million in costs
         anticipated to be incurred for employee retention, work force
         reduction, facility consolidation and other reorganization related
         costs.

         The estimated fair value of the common stock to be issued is based on
         the average closing price of Healtheon's common stock on the five days
         prior and subsequent to the day the reorganization was announced, which
         was May 20, 1999. The estimated fair value of the options and warrants
         to be assumed is based on the Black-Scholes model using the following
         assumptions:

         - Expected lives of one-half to 2.5 years

         - Expected volatility factor of 1.0

         - Risk-free interest rate of 4.5%

         - Expected dividend rate of 0%

     (2) Recognition of the excess purchase price of approximately $6,600.0
         million over the fair value of net tangible assets acquired, has been
         recorded as goodwill and other intangible assets.

     (3) To reflect the elimination of the historical stockholders' equity
         accounts of WebMD.

     (4) To reflect the elimination of goodwill and other intangible assets on
         the balance sheet of WebMD as of the acquisition date.

     (5) To reflect the proceeds, net of offering costs, relating to investments
         in capital stock made or to be made by strategic partners prior to the
         consummation of the reorganization. The reorganization agreement
         requires that these investments be completed prior to the closing of
         the reorganization.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
             COMBINED WITH WEBMD FINANCIAL INFORMATION (CONTINUED)

     The adjustments to the unaudited pro forma condensed combined statements of
operations for the quarter ended March 31, 1999 and year ended December 31,
1998, assume the reorganization occurred as of January 1, 1999 and January 1,
1998 and are as follows:

     (A) To reflect the amortization of goodwill and other intangible assets
         resulting from the reorganization. The goodwill and other intangible
         assets are being amortized over periods of approximately three years.
         Currently, management does not anticipate that any significant value
         will be attributed to purchased in-process research and development.

     (B) Basic and diluted net loss per share has been adjusted to reflect the
         issuance of 62.1 million shares of Healtheon/WebMD's common stock, as
         if the shares had been outstanding for the entire periods presented.
         The effect of stock options and warrants of WebMD assumed in the
         reorganization have not been included as their inclusion would be
         anti-dilutive.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                COMBINED WITH MEDE AMERICA FINANCIAL INFORMATION

     The unaudited pro forma condensed combined financial information reflects
the MEDE AMERICA reorganization and gives effect to certain reclassifications to
the unaudited historical financial statements to conform the presentation of the
historical operations of the merged companies.

     The total estimated purchase price of the reorganization has been allocated
on a preliminary basis to assets and liabilities based on management's estimate
of their fair values. The excess of the purchase price over the fair value of
the net assets acquired has been allocated to goodwill and other intangible
assets. This allocation is subject to change pending the completion of the final
analysis of the total purchase price and the fair value of the assets acquired
and liabilities assumed. The impact of such changes could be material.

     The adjustments to the unaudited pro forma condensed combined balance sheet
as of March 31, 1999, have been calculated as if the reorganization occurred on
March 31, 1999 and are as follows:

     (1) To reflect the acquisition of all of the outstanding capital stock of
         MEDE AMERICA by exchanging 0.6593 shares of Healtheon/WebMD common
         stock for each share of MEDE AMERICA common stock for a total estimated
         purchase price of approximately $525.3 million. The purchase
         consideration consists of the issuance of an estimated 8.5 million
         shares of Healtheon/WebMD's common stock with a fair value of
         approximately $440.4 million and the assumption of options and warrants
         to purchase 1.5 million shares of Healtheon/WebMD's common stock with a
         fair value of approximately $61.1 million and other related
         reorganization costs of approximately $23.8 million, consisting
         primarily of approximately $12.4 million in investment banking, legal,
         accounting and regulatory filing fees, and approximately $11.4 million
         in costs anticipated to be incurred for employee retention, work force
         reduction, facility consolidation and other reorganization related
         costs.

        The estimated fair value of the common stock to be issued is based on
        the average closing price of Healtheon's common stock on the five days
        prior and subsequent to the day the reorganization was announced, which
        was April 21, 1999. The estimated fair value of the options and warrants
        to be assumed is based on the Black-Scholes model using the following
        assumptions:

        - Expected lives of one-half to 2.5 years

        - Expected volatility factor of 1.0

        - Risk-free interest rate of 4.5%

        - Expected dividend rate of 0%

        The purchase price for MEDE AMERICA may be increased or decreased by 25%
        based upon the lower average closing price of Healtheon's stock for the
        10 day periods ending July 30, 1999 and ending two days prior to the
        special meeting of MEDE AMERICA stockholders, if that lower average
        stock price exceeds $63.70 or is below $38.39.

     (2) Recognition of the excess purchase price of approximately $512.6
         million over the fair value of net tangible assets acquired, has been
         recorded as goodwill and other intangible assets.

     (3) To reflect the elimination of the historical stockholders' equity
         accounts of MEDE AMERICA.

     (4) To reflect the elimination of goodwill and other intangible assets on
         the balance sheet of MEDE AMERICA as of the acquisition date.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
          COMBINED WITH MEDE AMERICA FINANCIAL INFORMATION (CONTINUED)

     The adjustments to the unaudited pro forma condensed combined statements of
operations for the quarter ended March 31, 1999 and year ended December 31,
1998, assume the reorganization occurred as of January 1, 1999 and January 1,
1998 and as follows:

     (A) To reflect the amortization of goodwill and other intangible assets
         resulting from the reorganization. The goodwill and other intangible
         assets are being amortized over periods of approximately four years.
         Currently, management does not anticipate that any significant value
         will be attributed to purchased in-process research and development.

     (B) Basic and diluted net loss per share have been adjusted to reflect the
         issuance of approximately 8.5 million shares of Healtheon/WebMD's
         common stock, as if the shares had been outstanding for the entire
         periods presented. The effect of stock options and warrants of MEDE

                       COMPARISON OF RIGHTS OF HOLDERS OF
                            WEBMD CAPITAL STOCK AND
                          HEALTHEON/WEBMD COMMON STOCK

     This section of the proxy statement/prospectus describes certain
differences between WebMD capital stock and Healtheon/WebMD common stock. While
we believe that the description covers the material differences between the two,
this summary may not contain all of the information that is important to WebMD
stockholders, including the certificate of incorporation and bylaws of
Healtheon/WebMD and the articles of incorporation and bylaws of WebMD. WebMD
stockholders should read this entire document and the other documents referred
to carefully for a more complete understanding of the differences between WebMD
capital stock and Healtheon/WebMD common stock.

     WebMD's articles of incorporation and bylaws and Georgia law currently
govern the rights of stockholders of WebMD. After the completion of the
Healtheon-WebMD reorganization, WebMD's common stockholders will become
stockholders of Healtheon/WebMD. As a result, WebMD common stockholders' rights
will be governed by Healtheon/WebMD's certificate of incorporation and bylaws.
Furthermore, because Healtheon/WebMD is a Delaware corporation, after the
Healtheon-WebMD reorganization the rights of WebMD common stockholders will be
governed by Delaware law, rather than Georgia law. The following paragraphs
summarize certain differences between the rights of Healtheon/ WebMD
stockholders and WebMD stockholders under the certificate of incorporation and
bylaws of Healtheon/WebMD and articles of incorporation and bylaws of WebMD, and
under Delaware and Georgia law, as applicable.

DESCRIPTION OF HEALTHEON/WEBMD CAPITAL STOCK

     The authorized capital stock of Healtheon/WebMD consists of 600,000,000
shares of common stock, par value $0.0001 per share, and 10,000,000 shares of
preferred stock, par value $0.0001 per share.

Healtheon/WebMD Common Stock

     As of June 15, 1999, no shares of common stock were outstanding. After
giving effect to the transactions contemplated by the reorganizations, there
will be approximately 144,000,000 shares of common stock outstanding. The
holders of common stock are entitled to one vote per share on all matters to be
voted upon by the stockholders. Stockholders may not cumulate votes in
connection with the election of directors. The holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available therefor. In
the event of a liquidation, dissolution or winding up of Healtheon/WebMD, the
holders of common stock are entitled to share ratably in all assets remaining
after payment of liabilities and payment of liquidation preferences to holders
of preferred stock, if any. The Healtheon/WebMD common stock has no preemptive
rights or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and non-assessable, and the
shares of common stock to be outstanding upon completion of the WebMD
reorganization will be fully paid and non-assessable.

Preferred Stock

     Healtheon/WebMD has 10,000,000 shares of preferred stock authorized, of
which no shares are outstanding. The Healtheon/WebMD board has the authority to
issue these shares of preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions, qualifications and limitations
granted to or imposed upon any unissued and undesignated shares of preferred
stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
stockholders, subject to applicable stock exchange rules. The Healtheon/WebMD
board, without stockholder approval, subject to applicable stock exchange rules,
can issue preferred stock with voting and conversion rights which could
adversely affect the voting power or other rights of the holders of

                                       126
<PAGE>   137

common stock and the issuance of preferred stock may have the effect of
delaying, deferring or preventing a change in control of Healtheon/WebMD.

event of a liquidation, dissolution or winding up of WebMD, the holder of each
share of Series B preferred stock is entitled to receive, at their election, in
exchange for and in redemption of such share, on a parity with the holders of
any capital stock ranking on a parity with the Series B preferred stock, from
any funds legally available for distribution to stockholders, that portion of

share of Series B preferred stock is convertible, divided by (2) the sum of the
aggregate number of shares of common stock into which all shares of Series B
preferred stock are convertible, plus all other shares of common stock of all
series outstanding, plus all other shares of capital stock of WebMD outstanding
which are entitled to participate in the proceeds of a liquidation, dissolution

holders of WebMD common stock and preferred stock are presently governed by
Georgia law and by WebMD's amended and restated articles of incorporation and
WebMD's amended and restated bylaws and the rights of the holders of WebMD
preferred stock will continue to be governed by Georgia law, the WebMD articles
and the WebMD bylaws. As stockholders of Healtheon/ WebMD, the rights of the
holders of the WebMD common stock will be governed by Delaware law and

                                       132
<PAGE>   143

by Healtheon/WebMD's amended and restated certificate of incorporation and
Healtheon/WebMD's bylaws. The following discussion summarizes the material
differences between the rights of holders of WebMD common stock and preferred
stock and the rights of holders of Healtheon/WebMD common stock, and the
material differences between the charters and bylaws of WebMD and
Healtheon/WebMD. This summary does not purport to be complete and is qualified
by reference to Healtheon/WebMD's certificate and Healtheon/WebMD's bylaws,
WebMD's articles and WebMD's bylaws and the relevant provisions of Delaware and
Georgia law.

     Size of the Board of Directors. Healtheon/WebMD's bylaws provide for a
board of directors of not less than six nor more than eleven directors. The
Healtheon/WebMD board has the sole authority to determine the number of
directors and may increase or decrease the number of directors from time to
time, but a decrease in the number of directors may not have the effect of
shortening the term of any incumbent director. WebMD's bylaws provide for a
board of directors consisting of a maximum of fifteen members. The WebMD board
of directors may change the number of directors from time to time by resolution
so long as the number does not exceed fifteen, provided that a decrease in the
number of directors (if more than one director is elected by a resolution of the
board of directors or the stockholders) will not have the effect of shortening
the term of an incumbent director.

     Loans to Officers and Employees. Under Delaware law, a corporation may make
loans to, guarantee the obligations of or otherwise assist its officers or other
employees and those of its subsidiaries (including directors who are also
officers or employees) when such action, in the judgment of the directors, may
reasonably be expected to benefit the corporation. Georgia law does not contain
a similar provision.

     Voting by Ballot. Under Delaware law, the right to vote by written ballot
may be restricted if so provided in the certification of incorporation.
Healtheon/WebMD's certificate and bylaws do not restrict the right to vote by
ballot. Georgia law does not contain a similar provision and the WebMD articles
and bylaws do not specify any rules for accepting voice or ballot votes.

     Cumulative Voting. In an election of directors under cumulative voting,
each share of stock normally having one vote is entitled to a number of votes
equal to the number of directors to be elected. A stockholder may then cast all
such votes for a single candidate or may allocate them among as many candidates
as the stockholder chooses. Under Delaware law, cumulative voting in the
election of directors is not available unless specifically provided for in the
certificate of incorporation. According to Georgia law, unless otherwise
provided in the articles of incorporation, shareholders do not have a right to
cumulate their votes for directors. Healtheon/WebMD has not provided for
cumulative voting in Healtheon/ WebMD's Certificate and cumulative voting is
therefore not available to Healtheon/WebMD's stockholders. WebMD has not
provided for cumulative voting in WebMD's Articles and cumulative voting is
therefore not available to WebMD's stockholders.

     Classified Board of Directors. A classified board of directors is one on
which a certain number of the directors are elected on a rotating basis each
year. This method of electing directors makes changes in the composition of the
board of directors, and thus a potential change in control of a corporation, a
lengthier and more difficult process. Delaware and Georgia law both permit, but
do not require, a classified board of directors, with staggered terms under
which one-half or one-third of the directors are elected for terms of two or
three years, respectively. The Healtheon/WebMD Board is classified in accordance
with its certificate into three classes, with directors assigned to each class
in accordance with a resolution or resolutions adopted by the board of
directors. Each class is elected to a three-year term, with the term of office
of one class expiring each year. The WebMD board is divided into three classes
of directors, with each class as nearly equal in number as possible, and each
serving for staggered three year terms.

     Power to Call Special Stockholders' Meetings; Advance Notice of Stockholder
Business and Nominees. Under both Delaware and Georgia law, a special meeting of
stockholders may be called by the board of directors or any other person
authorized to do so in the certificate or articles of incorporation or the
bylaws. In addition, Georgia law provides that a special meeting of stockholders
may also be called by the holders of at least 25%, or such greater or lesser
percentages as the articles of incorporation or bylaws provide, of all votes
entitled to be cast on any issue proposed to be considered at a special meeting.
                                       133
<PAGE>   144

Healtheon/WebMD's bylaws authorize the board of directors, the president of
Healtheon/WebMD, or one or more stockholders holding shares in the aggregate
entitled to cast no less than 10% of the votes at that meeting to call a special
meeting of stockholders. Healtheon/WebMD's bylaws require 90 days advance notice
in proper written form of stockholder nominees for election as director or
stockholder business to be brought before a meeting and provide that no such
business shall be conducted at a stockholder meeting unless the stockholder
follows the procedures set forth in the Healtheon/WebMD bylaws. WebMD's bylaws
allow the WebMD board of directors, the chairman of the board, the chief
executive officer of WebMD, or the holders of shares representing at least a
majority of the votes entitled to be cast on each issue presented at such
meeting to call a meeting of stockholders or any class or series of
stockholders. WebMD's bylaws contain no advance notice provisions similar to
those contained in Healtheon/WebMD's bylaws with respect to special meetings of
stockholders.

     Elimination of Actions by Written Consent of Stockholders. Under Delaware
and Georgia law, stockholders may take action by written consent in lieu of
voting at a stockholders meeting. Delaware law permits a corporation, pursuant
to a provision in such corporation's certificate of incorporation, to eliminate
the ability of stockholders to act by written consent. Elimination of the
ability of stockholders to act by written consent could lengthen the amount of
time required to take stockholder actions because certain actions by written
consent are not subject to the minimum notice requirements of a stockholders'
meeting, and could therefore deter hostile takeover attempts. If the ability of
stockholders to act by written consent is eliminated, a holder or group of
holders controlling a majority in interest of a corporation's capital stock, for
example, would not be able to amend such corporation's bylaws or remove its
directors pursuant to a stockholders' written consent. Healtheon/WebMD's
certificate eliminates the ability of stockholders to act by written consent.
Under Georgia law, all actions taken by written consent must be unanimous unless
the articles of incorporation provide otherwise. WebMD's articles provide that
all actions by stockholders shall be taken at a meeting of the stockholders.

     Stockholder Approval of Certain Business Combinations. In the last several
years, a number of states have adopted special laws designed to make certain
kinds of "unfriendly" corporate takeovers, or other transactions involving a
corporation and one or more of its significant stockholders, more difficult.
Under Delaware and Georgia law, certain "business combinations" by corporations
with "interested stockholders" are subject to a moratorium of three or five
years, respectively, unless specified conditions are met. The prohibited
transactions include, in each case, a merger with, disposition of assets to, or
the issuance of stock to, the interested stockholder, or certain transactions
that have the effect of increasing the proportionate share of the outstanding
securities held by the interested stockholder. Under Delaware law, an interested
stockholder may avoid the prohibition against effecting certain significant
transactions with the corporation if the board of directors, prior to the time
such stockholder becomes an interested stockholder, approves such transaction or
the transaction by which such stockholder becomes an interested stockholder or
if at or subsequent to such time the board of directors and the stockholders
approve such transaction. Under Georgia law, an interested stockholder may avoid
the prohibition against effecting certain significant transactions with the
corporation if the board of directors, prior to the time such stockholder
becomes an interested stockholder approves such transaction or the transaction
by which such stockholder becomes an interested stockholder. These provisions of
Delaware law apply to a Delaware corporation unless the corporation "opts out"
of the provisions in its certificate of incorporation or bylaws. Healtheon/WebMD
has not opted out of these provisions in its certificate of incorporation or
bylaws and consequently is subject to these provisions. The similar provisions
of Georgia law do not apply to a Georgia corporation unless it has affirmatively
elected in its bylaws to be governed by them. The WebMD bylaws do not currently
contain a provision electing to be governed by the similar provisions of Georgia
law. Georgia law also contains a provision concerning "fair price requirements"
which if elected by a Georgia corporation in its bylaws imposes certain
requirements on "business combinations" of a Georgia corporation with any person
who is an "interested stockholder" of that corporation. The WebMD bylaws do not
presently contain a provision electing to be governed by the fair price
requirements.

     Share Purchase Rights Plans. Neither Healtheon/WebMD nor WebMD has adopted
a "poison pill" rights plan.

                                       134

     Removal of Directors. Under Delaware and Georgia law, except as otherwise
provided in the corporation's certificate or articles of incorporation, a
director of a corporation that has a classified board of directors may be
removed only with cause. A director of a corporation that does not have a
classified board of directors or cumulative voting may be removed, with or
without cause, with the approval of a majority of the outstanding shares
entitled to vote. If cumulative voting is authorized, a director may not be
removed if the number of votes sufficient to elect such director is voted
against his removal. In addition, under Delaware law, when a corporation's
certificate of incorporation provides that holders of a series or class, voting
as a class or series, are entitled to elect one or more directors, then any
director may be removed, without cause, only by the applicable vote of holders
of shares of that class or series. Under Georgia law, if a director is elected
by a voting group, only the stockholders of that voting group may participate in
the vote to remove such director. Delaware law does not permit directors to
remove other directors. Healtheon/WebMD's bylaws provide that a director may be
removed with or without cause by the holders of a majority of the outstanding
shares of all classes of capital stock of the corporation entitled to vote in
the election of directors. WebMD's bylaws provide that any director, or the
entire WebMD board of directors, may be removed with cause by the stockholders,
provided that directors elected by a particular voting group may be removed only
by the stockholders in that voting group. WebMD's bylaws do not allow directors
to be removed without cause.

     Filling Vacancies on the Board of Directors. Under Delaware law, vacancies
and newly created directorships may be filled by a majority of the directors
then in office (even though less than a quorum) unless otherwise provided in the
certificate of incorporation or bylaws (and unless the certificate of
incorporation directs that a particular class of stock is to elect such
director, in which case any other directors elected by such class, or a sole
remaining director so elected, may fill such vacancy). Under Georgia law, unless
the articles of incorporation or a bylaw adopted by the stockholders provides
otherwise, vacancies and newly created directorships may be filled by the
stockholders, by the board of directors, or by a majority of the directors
remaining in office if such directors constitute less than a quorum (unless the
director was elected by a voting group, in which case the stockholders of such
voting group or the remaining directors elected by such voting group may fill
such vacancy). Healtheon/WebMD's bylaws provide that vacancies may be filled by
a majority of the directors then in office, though less than a quorum, unless
the board of directors determines by resolution that any such vacancy shall be
filled by the stockholders. WebMD's bylaws provided that a vacancy may be filled
by the affirmative vote of a majority of the remaining directors, provided that
if the vacant office was held by a director elected by a particular voting
group, only the holder of shares of such voting group or the remaining directors
elected by such voting group may fill the vacancy, provided further that if
there is no remaining director elected by such voting group, the other remaining
directors may fill the vacancy during an interim period before the stockholders
of the applicable voting group act to fill the vacancy.

     Indemnification and Limitation of Liability. Delaware and Georgia have
similar laws relating to indemnification by a corporation of its officers,
directors, employees and other agents. The laws of both states permit
corporations to adopt a provision in their charters eliminating the liability of
a director to the corporation or its stockholders for monetary damages for
breach of the director's fiduciary duty of care. There are nonetheless certain
differences between the laws of the two states with respect to indemnification
and limitation of liability.

     Healtheon/WebMD's certificate limits or eliminates, to the fullest extent
permitted by Delaware law, the personal liability of a director to
Healtheon/WebMD or its stockholders for monetary damages for breach of fiduciary
duty as a director. Under Delaware law, such provision may not eliminate or
limit director monetary liability for (i) breaches of the director's duty of
loyalty to the corporation or its stockholders; (ii) acts or omissions not in
good faith involving intentional misconduct or knowing violations of law; (iii)
the payment of unlawful dividends or unlawful stock repurchases or redemptions;
or (iv) transaction in which the director received an improper personal benefit.
Such limitation of liability provisions do not affect the availability of
non-monetary remedies such as injunctive relief or rescission.

     WebMD's articles eliminate a director's personal liability for monetary
damages to WebMD or any of its stockholders for any breach of duties of such
position, except that such liability is not eliminated for
                                       135
<PAGE>   146

(i) any appropriation, in violation of such director's duties, of any business
opportunity of WebMD, (ii) acts or omission which involve intentional misconduct
or a knowing violation of law, (iii) liability for unlawful distributions and
(iv) any transaction from which the director received an improper personal
benefit. WebMD's Articles provide that if at any time Georgia law is amended to
further eliminate or limit the liability of a director, then the liability of
each director of WebMD shall be eliminated or limited to the fullest extent
permitted thereby.

     Delaware law states that the indemnification provided by statute shall not
be deemed exclusive of any other rights under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise. Healtheon/WebMD's
certificate contains a provision providing that Healtheon/WebMD must indemnify
its directors and officers to the fullest extent permissible under Delaware law.
WebMD's bylaws state that the indemnification provided thereby shall not be
deemed exclusive of any other rights under any bylaw, resolution or agreement
approved or ratified by the holders of a majority of the shares entitled to vote
thereon.

     Inspection of Stockholders List. Both Delaware and Georgia law allow
stockholders to inspect and copy the stockholders list for a purpose reasonably
related to such person's interest as a stockholder.

     Par value, Dividends and Repurchases of Shares. Georgia law dispenses with
the concept of par value of shares for most purposes as well as statutory
definitions of capital, surplus and the like. The concepts of par value, capital
and surplus are retained under Delaware law.

     Delaware law permits a corporation to declare and pay dividends out of (i)
surplus or (ii) if there is no surplus, out of the net profits for the fiscal
year in which the dividend is declared and/or for the preceding fiscal year as
long as the amount of capital of the corporation following the declaration and
payment of the dividend is not less than the aggregate amount of the capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets. In addition, Delaware law generally
provides that a corporation may redeem or repurchase its shares only if such
redemption or repurchase would not impair the capital of the corporation.
Notwithstanding the foregoing, a Delaware corporation may redeem or repurchase
shares having a preference upon the distribution of any of its assets (or shares
of common stock, if there are no such shares of preferred stock) if such shares
will be retired upon acquisition (and provided that, after the reduction in
capital made in connection with such retirement of shares, the corporation's
remaining assets are sufficient to pay any debts not otherwise provided for).

     Under Georgia law, a corporation may make distributions to its stockholders
subject to any restrictions imposed in the corporation's articles of
incorporation, except that no distribution may be made if, after giving it
effect: (i) the corporation would not be able to pay its debts as they become
due in the usual course of business, or (ii) the corporation's total assets
would be less than the sum of its total liabilities plus (unless the articles of
incorporation permit otherwise) the amount that would be needed, if the
corporation were to be dissolved at the time of the distribution, to satisfy the
preferential rights upon dissolution of stockholders whose preferential rights
are superior to those receiving the distribution. A Georgia corporation may
acquire its own shares and shares so acquired will constitute authorized but
unissued shares, unless the articles of incorporation provide that such shares
become treasury shares or prohibit the reissuance of reacquired shares. If such
reissuance is prohibited, the number of authorized shares will be reduced by the
number of shares reacquired.

     Stockholder Voting on Mergers and Similar Transactions. Delaware law
requires that the holders of a majority of the outstanding voting shares of the
acquiring and target corporations approve statutory mergers. Delaware law does
not provide explicitly for share exchanges. Delaware law does not require a
stockholder vote of the surviving corporation in a merger (unless the
corporation provides otherwise in its certificate of incorporation) if: (i) the
merger agreement does not amend the existing certificate of incorporation; (ii)
each share of the surviving corporation outstanding before the merger is equal
to an identical outstanding or treasury share of the surviving corporation after
merger; and (iii) the number of shares to be issued by the surviving corporation
in the merger does not exceed 20% of the shares

                                       136
<PAGE>   147

outstanding immediately prior to the merger. The Healtheon/WebMD certificate
does not contain a provision which alters the voting requirements with respect
to mergers.

     Georgia law contains a similar exception to its voting requirements for
mergers and share exchanges where (i) the articles of incorporation of the
surviving corporation will not differ from its articles before the merger; (ii)
each stockholder of the surviving corporation whose shares were outstanding
immediately before the merger will hold the same number and type of shares
immediately after the merger; (iii) the number and kind of shares outstanding
immediately after the merger, plus the number and kind of shares issuable as a
result of the merger, do not exceed the total number and kind of shares of the
surviving corporation authorized by its articles of incorporation immediately
before the merger.

     Georgia law generally requires the affirmative vote of a majority of all
votes entitled to be cast on the matter, voting as a single group, to approve
mergers and share exchanges. Delaware and Georgia law both require that a sale
of all or substantially all of a corporation's assets be approved by a majority
of the outstanding voting shares of the corporation transferring such assets.
WebMD's articles provide that the holders of a majority of the Series E
preferred stock, voting together as a single class, and the holders of a
majority of WebMD's Series F preferred stock, voting together as a single class,
are required to approve certain mergers and similar transactions.

     Interested Director Transactions. Under both Delaware and Georgia law,
certain contracts or transactions in which one or more of a corporation's
directors has an interest are not void or voidable because of such interest,
provided that certain conditions, such as obtaining the required approvals and
fulfilling the requirements of good faith and full disclosure are met. With
certain exceptions, the conditions are substantially similar under Delaware and
Georgia law.

     Dissenters' or Appraisal Rights. Under both Delaware and Georgia law, a
stockholder of a corporation participating in certain major corporate
transactions may be entitled to dissenters' or appraisal rights pursuant to
which such stockholder may receive cash in the amount of the fair value of his
or her shares in lieu of the consideration he or she would otherwise receive in
the transaction. Under Delaware law, such rights are not available (1) with
respect to the sale, lease or exchange of all or substantially all of the assets
of a corporation or an amendment to the corporation's certificate of
incorporation (unless otherwise provided in the corporation's certificate of
incorporation); (2) with respect to a merger or consolidation by a corporation
the shares of which are either listed on a national securities exchange or held
of record by more than 2,000 stockholders if such stockholders are required to
receive only shares of the surviving corporation, shares of any other
corporation which are either listed on a national securities exchange or held of
record by more than 2,000 holders, cash in lieu of fractional shares or a
combination of the foregoing; or (3) to stockholders of a corporation surviving
the merger if no vote of the stockholder of the surviving corporation is
required to approve the merger because the merger does not amend the certificate
of incorporation, and each share of the surviving corporation outstanding prior
to the merger is an identical outstanding or treasury share after the merger,
and the number of shares to be issued in the merger does not exceed 20% of the
shares of the surviving corporation outstanding immediately prior to the merger.

     In contrast, under Georgia law, dissenters' rights are available in the
event of any of the following corporate actions: (1) a merger if the approval of
the stockholders is required for such merger and the stockholder is entitled to
vote on the merger or if the corporation is a subsidiary that is merged with its
parent, (2) a share exchange in which the corporation's shares will be acquired,
if the stockholder is entitled to vote on the share exchange, (3) a sale or
exchange of all or substantially all of the assets of a corporation, if a
stockholder vote is required, other than a sale pursuant to a court order or a
sale for cash the proceeds of which will be distributed to the stockholders
within one year, (4) an amendment of the articles of incorporation that
adversely affects rights relating to such stockholder's shares or (5) any
corporate action taken pursuant to a stockholder vote to the extent the articles
of incorporation, bylaws or a resolution of the board of directors provides that
voting or nonvoting stockholders are entitled to dissent and obtain payment for
their shares. This right is not available when the affected shares are listed on
a national securities exchange or held of record by more than 2,000 stockholders
unless (1) the articles of

                                       137
<PAGE>   148

incorporation or a resolution of the board of directors approving the
transaction provide otherwise, or (2) in a plan of merger or share exchange, the
holders of such shares are required to accept anything other than shares of the
surviving corporation or another publicly held corporation which at the
effective date of the merger or share exchange are either listed on a national
securities exchange or held of record by more than 2,000 stockholders, except
for payments in lieu of fractional shares. Appraisal rights are available to the
holders of the common stock and holders of the Series A preferred stock of WebMD
with respect to the WebMD merger.

     Dissolution. Under Delaware law, unless a majority of the whole board of
directors approves a proposal to dissolve, a dissolution must be approved by
stockholders holding 100% of the total voting power of the corporation. Only if
a dissolution is initially approved by a majority of the whole board of
directors may it be approved by a simple majority of the corporation's
outstanding shares of capital stock entitled to vote thereon. Delaware law
allows a Delaware corporation to include in its certificate of incorporation a
super majority voting requirement in connection with dissolutions initiated by
the board of directors. Healtheon/WebMD's certificate contains no such super
majority voting requirements. Georgia law requires approval of the board of
directors (unless the board elects because of a conflict of interest or other
special circumstances to make no recommendation) and the holders of a majority
of all the votes entitled to be cast (unless the articles of incorporation
require a greater vote or voting by groups) for voluntary dissolution of a
corporation. WebMD's articles contain no such super majority or voting group
voting requirement.

     Stockholder Derivative Suits. Under Delaware law, a stockholder may only
bring a derivative action on behalf of the corporation if the stockholder was a
stockholder at the time of the transaction in question or his or her stock
thereafter devolved upon him or her by operation of law. Under Georgia law, a
stockholder may not commence or maintain a derivative proceeding unless the
stockholder was a stockholder of the corporation at the time of the act or
omission complained of or became a stockholder through transfer by operation of
law from one who was a stockholder at that time. In addition, Georgia law
requires that the stockholder fairly and adequately represent the interests of
the corporation in enforcing the rights of the corporation.

                       COMPARISON OF RIGHTS OF HOLDERS OF
                         MEDE AMERICA COMMON STOCK AND
                          HEALTHEON/WEBMD COMMON STOCK

     This section of the proxy statement/prospectus describes certain
differences between MEDE AMERICA common stock and Healtheon/WebMD common stock.
While we believe that the description covers the material differences between
the two, this summary may not contain all of the information that is important
to MEDE AMERICA stockholders, including the certificates of incorporation and
bylaws of each company. MEDE AMERICA stockholders should read this entire
document and the other documents referred to carefully for a more complete
understanding of the differences between MEDE AMERICA common stock and
Healtheon/WebMD common stock.

     The rights of stockholders of MEDE AMERICA are currently governed by MEDE
AMERICA's certificate of incorporation, as amended and restated, and MEDE
AMERICA's bylaws. After the completion of the MEDE AMERICA reorganization, MEDE
AMERICA stockholders will become stockholders of Healtheon/WebMD. The rights of
stockholders of Healtheon/WebMD will be governed by Healtheon/WebMD's
certificate of incorporation and Healtheon/WebMD's bylaws. Because MEDE AMERICA
and Healtheon/WebMD are both Delaware corporations, after the MEDE AMERICA
reorganization the rights of MEDE AMERICA stockholders will continue to be
governed by the Delaware General Corporation Law, or the DGCL. The following
paragraphs summarize certain differences between the rights of Healtheon/WebMD
stockholders and MEDE AMERICA stockholders under the certificates of
incorporation and bylaws of Healtheon/WebMD and MEDE AMERICA, as applicable.

CLASSES OF COMMON STOCK

     Healtheon/WebMD and MEDE AMERICA each have one class of common stock issued
and outstanding. Holders of Healtheon/WebMD common stock and holders of MEDE
AMERICA common stock are each entitled to one vote for each share held.

SPECIAL MEETING OF STOCKHOLDERS

     Special meetings of Healtheon may be called by Healtheon/WebMD's board of
directors, by Healtheon/WebMD's president or by written request of the holders
of not less than 10% of the votes at that meeting.

     Special meetings of MEDE AMERICA may be called by the chairman of MEDE
AMERICA's board of directors, by MEDE AMERICA's president or by majority of MEDE
AMERICA's board of directors.

ACTION BY WRITTEN CONSENT IN LIEU OF A STOCKHOLDER'S MEETING

     Healtheon/WebMD stockholders may not take action without a meeting by
written consent.

     MEDE AMERICA stockholders may take action without a meeting by written
consent of the holders of outstanding stock having the number of votes that
would be necessary to take such an action at a meeting at which all shares
entitled to vote were present and voted.

VOTING BY WRITTEN BALLOT

     Healtheon/WebMD's bylaws do not contain any provision requiring a vote by
written ballots.

     MEDE AMERICA's bylaws provide that a vote at a stockholders' meeting need
not be by written ballot unless so demanded by a stockholder present in person
or by proxy at the meeting, or if so directed by the chairman of the meeting.

                                       139
<PAGE>   150

RECORD DATE FOR DETERMINING STOCKHOLDERS

     Both the Healtheon/WebMD bylaws and the MEDE AMERICA's bylaws provide that
their respective boards of directors may fix a record date that:

     - in the case of determination of the stockholders entitled to vote at any
       meeting of stockholders or adjournment of any meeting, shall not be more
       than 60 days nor less than 10 days before the date of the meeting;

     - in the case of any other action, shall not be more than 60 days prior to
       such other action.

     Furthermore, both the Healtheon/WebMD bylaws and the MEDE AMERICA bylaws
provide that if the respective board of directors does not fix a record date in
the manner described above, then:

     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders shall be at the close of business on
       the day next preceding the day on which notice is given, or, if notice is
       waived, at the close of business on the day next preceding the day on
       which the meeting is held;

     - the record date for determining stockholders for any other purpose shall
       be at the close of business on the same day on which the board of
       directors adopts the related resolution.

ADVANCE NOTICE PROVISIONS FOR BOARD NOMINATION AND OTHER STOCKHOLDER BUSINESS --
ANNUAL MEETINGS

     The Healtheon/WebMD bylaws require that nominations of persons for election
to the board of directors and the proposal of business to be considered at any
meeting of stockholders must made by (1) the corporation's notice of meeting,
(2) the board of directors or (3) a stockholder who gives proper notice. If made
by a stockholder, the proposal or nomination must be made by advance written
notice given to Healtheon/WebMD between 60 and 90 days prior to the first
anniversary of the preceding year's annual meeting of stockholders. However, if
less than 65 days notice of the meeting is given to the stockholder by
Healtheon/WebMD, the stockholder's notice of a proposal or nomination must be
delivered not earlier than the close of business on the seventh day following
the day on which the notice of the meeting is mailed.

     The MEDE AMERICA bylaws require that nominations of persons for election to
the board of directors and the proposal of business to be considered at an
annual meeting of stockholders must be made by (1) the board of directors or the
chairman of the meeting or (2) by a stockholder who gives proper notice. If made
by a stockholder, the proposal or nomination must be made by advance written
notice given to MEDE AMERICA between 60 and 90 days prior to the first
anniversary of the preceding year's annual meeting of stockholders.

ADVANCE NOTICE PROVISION FOR BOARD NOMINATION AND OTHER STOCKHOLDER
BUSINESS -- SPECIAL MEETINGS

     The Healtheon/WebMD bylaws provide for the same requirements for raising
business at special meetings of stockholders as for raising business at annual
meetings.

     The MEDE AMERICA bylaws provide that, at special meetings of stockholders,
the only business that can be conducted will be the items of business set forth
in the notice of the special meeting.

CLASSIFIED BOARD OF DIRECTORS

     Delaware law provides that a corporation's board of directors may be
divided into various classes with staggered terms of office. Healtheon/WebMD's
board of directors is divided into three classes, as nearly equal in size as
possible, with one class being elected annually. Healtheon/WebMD directors are
elected to a term of three years and until their successors are elected and
qualified.

     MEDE AMERICA's directors are not divided into classes. MEDE AMERICA's
directors are all elected each year to a term of one year. At an annual meeting
in which a quorum is present, the persons receiving a plurality of the votes
cast are elected as the directors.

REMOVAL OF DIRECTORS

     The Healtheon/WebMD bylaws provide that any director or the entire board of
directors may be removed, with cause, by the holders of a majority of the shares
then entitled to vote at an election of directors.

     The MEDE AMERICA bylaws provide that any director or the entire board of
directors may be removed, with or without cause, (1) by an action by the holders
of a majority of the shares present in person or by proxy at a stockholders'
meeting and entitled to vote or (2) by proper written consent of the
stockholders.

BOARD OF DIRECTORS VACANCIES

     The Healtheon/WebMD bylaws provide that vacancies on the board of directors
may be filled only by the vote of the majority of directors remaining in office.

     The MEDE AMERICA bylaws provide that vacancies on the board of directors
resulting from death, resignation or removal shall only be filled by the vote of
a majority of the directors remaining in office. Newly created directorships
created by any increase in the number of directors shall be filled by the board
of directors, or if not filled by the board of directors, by the stockholders at
the next annual meeting of at a special meeting called for that purpose.

NOTICE OF SPECIAL MEETINGS OF THE BOARD OF DIRECTORS

     The Healtheon/WebMD bylaws provide that the Chief Executive Officer may
call special meetings of the board of directors upon three days notice of the
meeting. The president or secretary may call special meetings upon the written
request of two directors and upon three days notice of the meeting.

     The MEDE AMERICA bylaws provide that special meetings may be called by the
Chairman of the board, the President or by a majority of the directors. Notice
of such a meeting must be mailed at least five days before the date of the
meeting, or delivered by telephone, telegraph, cable, radio or wireless no later
than one day before the date of the meeting.

APPROVAL OF LOANS TO OFFICERS

     The Healtheon/WebMD bylaws provide that Healtheon may lend money to or
otherwise assist any officer or other employee whenever the directors judge such
a loan or assistance reasonably to be expected to benefit the corporation.

     The MEDE AMERICA bylaws do not specifically address loans to officers or
employees.

PREFERRED STOCK

     Both the Healtheon/WebMD and MEDE AMERICA certificates of incorporation
authorize the respective boards of directors to issue shares of preferred stock
in one or more series and to fix the designations, preferences, powers and
rights of the shares to be included in each series. The Healtheon/

                                       141
<PAGE>   152

WebMD certificate of incorporation and the MEDE AMERICA certificate of
incorporation each reserve for issuance 5,000,000 shares of preferred stock.

INDEMNIFICATION

     Both the Healtheon/WebMD certificate of incorporation and bylaws and the
MEDE AMERICA certificate of incorporation and bylaws provide that its respective
directors and officers shall be indemnified to the fullest extent authorized by
law against any action, proceeding or suit brought against such a person by
reason of the fact that he or she is or was a director or officer of the
corporation or serves or served at any other enterprise as at the request of the
corporation.

     Both the Healtheon/WebMD bylaws and the MEDE AMERICA bylaws provide that
the respective corporations may pay all expenses incurred by a director or
officer in defending any proceeding within the scope of the indemnification
provisions. The MEDE AMERICA bylaws provide that payment of expenses in advance
of the final disposition of an action may be authorized by the board of
directors upon receipt of an undertaking by the director or officer to repay the
amount unless it is determined that he or she is entitled to be indemnified by
the corporation.

LIMITATION ON LIABILITY

     Both the Healtheon/WebMD certificate of incorporation and the MEDE AMERICA
certificate of incorporation provide that no director shall be personally liable
to the corporation or any of its stockholders for monetary damages for breach of
the director's fiduciary duty. The MEDE AMERICA certificate of incorporation
does not limit liability, however, (1) for a director's breach of his or her
duty of loyalty to the corporation or its stockholders, (2) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law, (3) under Section 174 of the DGCL or (4) for any
transaction from which the director derived an improper personal benefit. The
Healtheon/WebMD certificate of incorporation limits liability of its directors
to the fullest extent permitted by Delaware law.

directors of each of Healtheon and WebMD who will serve as executive officers or
directors of Healtheon/WebMD, see "Certain Information Regarding Healtheon" on
page 145 and "Certain Information Regarding WebMD" on page 185.

COMMITTEES OF THE BOARD OF DIRECTORS

     The board of directors of Healtheon/WebMD will have the following
committees:

Audit committee

     The audit committee will review and recommend to the board the internal
accounting and financial controls for Healtheon/WebMD and the accounting
principles and auditing practices and procedures to be used for the financial
statements of Healtheon/WebMD. The audit committee makes recommendations to the
board concerning the engagement of independent public accountants and the scope
of the audit to be undertaken by such accountants.

Stock option committee

     The stock option committee will be charged with overseeing the stock option
plans as they relate to employees other than officers and directors of
Healtheon/WebMD.

Compensation committee

     The compensation committee will review and recommend to the board policies,
practices and procedures relating to the compensation of the officers and other
managerial employees and the establishment and administration of employee
benefit plans. The compensation committee will exercise all authority under
Healtheon/WebMD's employee equity incentive plans and will advise and consult
with the officers of Healtheon/WebMD regarding managerial personnel policies.

COMPENSATION OF DIRECTORS

     Directors of Healtheon/WebMD will not receive any cash fees for their
services on the board or any board committee, but they will be entitled to
reimbursement for all reasonable out-of-pocket expenses incurred in connection
with their attendance at board and board committee meetings. All board members
will be eligible to receive Healtheon/WebMD Stock options under the Healtheon
1996 Stock Plan which will be assumed by Healtheon/WebMD in connection with the
reorganization.

COMPENSATION OF EXECUTIVE OFFICERS

     Healtheon/WebMD has not yet paid any compensation to any of its executive
officers and the form and amount of the compensation has not yet been
determined. The board will rely on its compensation committee to recommend the
form and amount of compensation to be paid to Healtheon/WebMD executive
officers.

                                       143
<PAGE>   154

     It is anticipated that when the compensation committee meets to determine
compensation, the committee will generally adhere to compensation policies which
reflect the belief that:

     - Healtheon/WebMD must attract and retain individuals of outstanding
       ability and motivate and reward them for sustained performance;

     - a significant portion of an executive's compensation should be at risk
       based upon that executive's and the Healtheon/WebMD's performance; and

     - levels of compensation should generally be in line with that offered by
       comparable corporations.

     For information concerning the compensation historically paid to the
executive officers of each of Healtheon and WebMD who will serve as executive
officers or directors of Healtheon/WebMD, see "Certain Information Regarding
Healtheon" on page 145 and "Certain Information Regarding WebMD" on page 185.

                              HEALTHEON'S BUSINESS

     Healtheon believes a significant opportunity exists to leverage the power
of the Internet to provide secure, open, universally accessible network services
that connect participants and automate workflows throughout the healthcare
delivery process. Healtheon believes that such a solution has the potential to
create significant improvements in the way that information is used by the
healthcare system, enabling improved workflows, better decision-making and,
ultimately, higher quality care at a lower cost.

The Healtheon Virtual Healthcare Network

     Healtheon is pioneering the use of the Internet to simplify workflows,
decrease costs and improve the quality of patient care throughout the healthcare
industry. Healtheon has designed an Internet-based information and transaction
platform that allows it to create Virtual Healthcare Networks that facilitate
and streamline interactions among the myriad participants in the healthcare
industry. The Healtheon VHN solution includes a suite of services delivered
through applications operating on its Internet-based platform. Healtheon VHNs
enable the secure exchange of information among disparate healthcare information
systems and support a broad range of healthcare transactions, including
enrollment, eligibility determination, referrals and authorizations, laboratory
and diagnostic test ordering, clinical data retrieval and claims processing.
Healtheon provides its own applications on the Healtheon Platform and also
enables third-party applications to operate on its platform. The Healtheon
Virtual Healthcare Network solution provides the following key benefits:

     Elimination of Unnecessary or Redundant Efforts. The Healtheon VHN solution
is designed to reduce paper-based transactions, eliminate redundant data entry,
shorten cycle times and decrease the communication inefficiencies created by
isolated proprietary systems. Healtheon believes that by decreasing redundant
tasks, errors, delays and unnecessary tests and procedures, it can create
efficiencies and reduce costs across the healthcare industry.

     Extendibility Across the Continuum of Healthcare. Healtheon leverages the
Internet to provide an open, low-cost information and transaction platform
capable of extending across a wide range of healthcare market segments. The
Healtheon VHN solution is designed to interconnect a broad range of practice
management, managed care, human resources and laboratory information systems.
Healtheon expects the benefits of its solution to increase as it adds customers,
enabling each user to exchange more data and complete more transactions with a
greater number and broader range of other healthcare industry participants.

     Scalability and Flexibility. The Healtheon VHN solution is designed to
support Healtheon's customers as their businesses grow and evolve. The Healtheon
Platform is designed to scale to accommodate high volumes of transactions and
large numbers of simultaneous users. In addition, Healtheon's object-oriented
platform provides flexibility so that customers can add or modify applications
and transaction capabilities to react to changes in the healthcare marketplace.

                                       145
<PAGE>   156

     High Degree of Security. To enable the use of the Internet for transmission
of highly sensitive and confidential data, Healtheon utilizes advanced
technology designed to ensure a high degree of security. This technology
includes strict authentication requirements, sophisticated data encryption
techniques, system-wide network security monitoring and tightly controlled
physical security systems. These safeguards are designed to provide a secure
environment for the exchange of confidential patient and customer data. The
Healtheon Platform is designed to enable compliance with proposed government
standards under the Health Insurance Portability and Accountability Act of 1996,
which mandate the acceptance by payers of electronic transactions as well as the
use of standard transactions, standard identifiers and security features by the
year 2000.

     Increased Accuracy and Timeliness of Information. The Healtheon VHN
solution is designed to increase information flows among all healthcare
participants, which ultimately results in more timely and appropriate
treatments. For example, on-line access to accurate, up-to-date eligibility
information facilitates patients' access to care on a more timely basis, reduces
frustration and costs and increases the likelihood that providers will be
compensated for their services in a timely manner. Similarly, using Healtheon's
VHN solution, consumers will have greater access to their healthcare
information, thereby enabling them to become more active participants in the
provision of their own healthcare.

Healtheon's Services

     Healtheon offers a suite of healthcare transaction and information services
delivered over the Internet or over private intranets and other networks. These
network-based services are provided by software applications operating on or
interfacing with the Healtheon Platform, which is designed to provide
connectivity across the healthcare industry and enable a broad array of secure,
mission-critical healthcare transactions. In addition to its platform and
Internet-based applications, Healtheon provides comprehensive consulting and
implementation services to enable its customers to take full advantage of the
capabilities of Healtheon's platform.

     Healtheon provides a broad range of applications and services that support
key healthcare transactions. The components of these application suites can be
combined and modified, or supplemented with new application components, to
provide custom solutions for large, complex, multi-entity business enterprises.
These applications and services are typically sold on a transaction or
subscription fee basis, which varies across customers and market segments. The
following chart summarizes the key transactions supported by Healtheon,
organized by business function.

</TABLE>

* Under development

+ Not Internet-enabled

     The primary applications and services currently available or under
development are described in greater detail below. Certain of these applications
were acquired by Healtheon and are not yet Internet-enabled; Healtheon is
currently redeveloping or replacing these applications to integrate them with
the Healtheon Platform.

     Membership Services. Healtheon provides membership services through its
Benefit Central service. The Benefit Central service utilizes internally
developed applications operating on the Healtheon Platform. The service provides
Internet-based connectivity between healthcare payers and consumers and supports
transactions such as selection of health plans and providers, enrollment for
benefits and benefit inquiries. Benefit Central users also receive Healtheon's
Health Risk Appraisal service, which provides consumer education in wellness and
health risks. Healtheon has contracted to deploy its Benefits Administration
service directly and through aggregators to 50 companies, covering approximately
190,000 members.

     Healthcare Administration and Financial Management. Healtheon supports or
will support healthcare administration and financial management transactions
through its ProviderLink, Healtheon Practice and Healtheon ProviderWorks
services. ProviderLink was licensed by Healtheon's ActaMed subsidiary from
UnitedHealth Group. Healtheon has developed a software interface between the
Healtheon Platform and ProviderLink to integrate ProviderLink with Healtheon's
network-based services. ProviderLink is used by providers to support
transactions and workflows with payers. ProviderLink supports transactions such
as eligibility determinations, claims submission and status, and remittance
advice. For example, physicians use ProviderLink to determine eligibility of
patients to receive care and to submit health claims to payers. ProviderLink is
currently deployed in over 4,850 active provider sites in more than 20 major
markets, and processes over 3.7 million transactions per month.

     Healtheon has developed Healtheon Practice, a new Internet-based provider
service with support from Brown & Toland Physician Services Organization, or
Brown & Toland, one of Healtheon's strategic partners. Healtheon Practice, which
is in production, is designed to provide all of the functionality of
ProviderLink and also support referrals, authorization, and provider directories
reporting. Providers using the Healtheon Practice service receive real-time
patient eligibility verifications and referral authorizations over the Healtheon
VHN.

     Healtheon is developing Healtheon ProviderWorks, a new Internet-based payer
service, with support from Beech Street Corporation, one of Healtheon's
strategic partners. Healtheon ProviderWorks is designed to support the creation
and management of networks of providers. The service is designed to manage
large, complex provider directories and files, manage provider relationships and
contracts and perform certain claim processing functions, such as claim
repricing. See "-- Strategic Relationships."

                                       147
<PAGE>   158

     Clinical Information Services. Healtheon's SCAN product supports ordering
and distribution of clinical tests and test results between SmithKline Beecham
Clinical Laboratories, Inc., or SmithKline Labs, and providers using SmithKline
Labs' services. ActaMed acquired the SCAN application from SmithKline Labs. SCAN
is deployed on approximately 5,100 installed workstations serving physicians
throughout the United States. SCAN is not Internet-enabled; however, Healtheon
is developing a new Internet-enabled application called Healtheon Dx, currently
in beta testing, that will combine the functionality of SCAN and ProviderLink.
See "-- Strategic Relationships."

     Healtheon's Global Master Person Index, or "GMPI," enables the unique
identification of a patient and reconciliation of multiple records for the same
patient contained on diverse information systems. GMPI also supports access to
patient data and registration information as well as clinical records. GMPI is
an object-oriented application developed by ActaMed and is not yet
Internet-enabled. Healtheon intends to adapt and implement GMPI functionality on
the Healtheon Platform.

     Online Consumer Information. Healtheon's recently introduced Consumer
Portal provides individual consumers with an authoritative source for healthcare
information and is intended to extend Healtheon's transaction services directly
to individual consumers. The Consumer Portal provides access to medical
dictionaries and encyclopedias, medical news, a food label and nutritional
library and customized wellness assessments. These sources include: Miller-Keane
Encyclopedia & Dictionary of Medicine, Nursing & Allied Health; Dorland's
Illustrated Medical Dictionary; Citizen 1's CitiLine index of authoritative
medical information; A.D.A.M.'s Hypertext Medical Encyclopedia; and Links to
medical headlines via the New York Times Syndicate. Healtheon's business
partners can integrate the Consumer Portal into their own sites to provide their
consumers with a single point of entry into the healthcare community.

     Healtheon expects to expand its Consumer Portal to support secure
communications and transactions between consumers and their providers and health
plans.

     Other Services. Healtheon also provides professional services to its
customers to enable them to define, develop and implement network-based
information systems that leverage the capabilities of the Healtheon Platform.
These services are typically sold on a fixed fee or time and materials basis.
These services include consulting on information systems strategy related to the
use of the Internet and secure networks, including design of information systems
functional specifications, mapping and redesign of business processes and
identification of enterprise transformation and training requirements to take
advantage of increased connectivity. Healtheon also provides custom development
of applications and enables the deployment of Healtheon services and integration
with legacy information technology systems. In addition, Healtheon provides
transitional network management services of its customers' networks. Healtheon
believes that its success is partially dependent upon its ability to introduce
new applications in several healthcare markets in a relatively short period of
time.

Customers and Markets

     Healtheon's target customers include providers, payers, suppliers and
consumers. Because Healtheon believes that the value and benefit of Healtheon's
services are directly related to both the number of participants using Healtheon
VHNs and the breadth of functionality supported, it intends initially to focus
on selected regions where it can quickly gain significant market acceptance.
Healtheon is presently targeting a number of regional markets across the United
States.

     Providers. Healtheon's target provider customers include aggregators of
individual physicians such as large medical groups, independent practice
associations, physician practice management companies and other large, organized
physician entities. In particular, Healtheon seeks to form strategic
relationships with providers with a high degree of involvement in managed care,
especially providers that are involved in activities such as capitation, which
require them to bear some level of insurance risk for each enrolled patient.
Healtheon's services for these providers include benefit eligibility
determinations, referrals and authorizations, claims processing, ordering of
clinical tests and delivery of results and maintenance of patient histories.
Healtheon also targets as potential customers large integrated delivery networks
that combine multiple healthcare facilities, such as hospitals, outpatient
facilities, labs and diagnostic centers,
                                       148

and affiliate with physicians and physician groups to coordinate care, contract
for managed care lives and manage healthcare resource utilization. Healtheon
offers these customers the following services: patient identification, patient
registration, ordering of clinical tests and delivery of results and
distribution of text documents across the network. Healtheon's current customers
in this category include Brown & Toland, Baylor Health Care System, Hill
Physician Group, Promina Health System and the Greater Dayton Area Hospital
Association.

     Payers. Healtheon's target payer customers include managed care
organizations, indemnity insurers, third-party administrators and federal and
state governmental agencies. Healtheon targets managed care organization
customers, such as mid-sized to large HMOs and PPOs. Healtheon's services for
these customers include eligibility determination, member customer service
functions, referral and authorization management, coordination of provider files
and directories, and submission and tracking of claims and patient encounter
reports. Healtheon targets indemnity insurer and third-party administrator
customers, such as mid-sized to large commercial entities, Medicare and other
agencies of federal and state government. Healtheon's current customers in this
category include UnitedHealth Group, Beech Street, Sun Life of Canada, Blue
Shield of California, CIGNA HealthCare and the Health Care Financing
Administration.

     Suppliers. Healtheon's target supplier customers include large national
laboratory companies, pharmaceutical companies and pharmacy benefit managers.
Healtheon's services for laboratory companies include ordering clinical tests
and reporting test results. Healtheon's customers in this category include
SmithKline Labs and Schering Corporation.

     Consumers. Healtheon's target consumer customers include employers, health
plans and health plan brokers. Healtheon's services in this area include a
consumer web portal, health plan enrollment, benefits administration and
membership coordination. Healtheon's target employer group includes mid-sized
and large employers and, particularly, self-funded employers that have complex
benefits management needs. Healtheon's target health plan broker customers
include mid-sized to large brokers that aggregate small and medium employers and
administer healthcare benefits on their behalf. Healtheon has contracted to
deploy it Benefits Administration service directly and through aggregators to 50
companies, covering approximately 190,000 members.

Strategic Relationships

     Healtheon has entered into several strategic relationships that it believes
will enhance its application portfolio, provide important specialized industry
expertise, increase its market penetration, and generate revenue. Certain of
these relationships are described below:

     UnitedHealth Group. UnitedHealth Group is one of the largest health and
well-being enterprises in the United States. UnitedHealth Group is Healtheon's
second largest stockholder and after the merger will own approximately 6.3% of
Healtheon's common stock. In March 1996, Healtheon acquired UnitedHealth Group's
ProviderLink network which currently supports over 4,850 active provider sites
in more than 20 major markets servicing over 3.7 million transactions per month.
Healtheon earns transaction fee revenue by providing certain healthcare
information services to UnitedHealth Group, members of UnitedHealth Group's
provider network and ProviderLink subscribers.

     In April 1996, Healtheon and UnitedHealth Group entered into a Services and
License Agreement, or the UnitedHealth Group Agreement, under which Healtheon,
using ProviderLink, provides claims processing, referral, eligibility and
enrollment services, to UnitedHealth Group's managed care providers and
customers. Under the UnitedHealth Group Agreement, Healtheon currently receives
a monthly fee for each user site enrolled with UnitedHealth Group and a fee per
transaction. However, the UnitedHealth Group Agreement does not guarantee any
minimum level of transactions or payments to Healtheon. The UnitedHealth Group
Agreement has a five year term; however, the agreement provides that two years
after the date of the agreement, the parties will agree on new prices that will
be competitive with the marketplace. Healtheon and UnitedHealth Group are
currently negotiating the new prices, and Healtheon anticipates that the new
prices will reduce the rates paid by UnitedHealth Group. UnitedHealth Group has
                                       149
<PAGE>   160

also agreed during the term of the UnitedHealth Group Agreement not to promote
or contract for services providing the same functionality as that provided by
Healtheon, although UnitedHealth Group is permitted to continue to utilize
services it was utilizing when it entered into the UnitedHealth Group Agreement.

     In addition, Healtheon has developed PLNet, an Internet-based version of
ProviderLink, which Healtheon intends to integrate into the Healtheon Platform
and offer to other major healthcare payers and providers. Healtheon is working
with UnitedHealth Group to expand the applications and content available to
UnitedHealth Group's provider network, to increase the size and geographic reach
of its provider network, and to assimilate newly acquired health plans. William
McGuire, M.D., the Chairman and CEO of UnitedHealth Group, is a member of
Healtheon's Board of Directors. The UnitedHealth Group Agreement is effective
through March 2001, subject to earlier termination in the event Healtheon fails
to meet certain network performance standards or otherwise breaches its material
obligations under the UnitedHealth Group Agreement.

     SmithKline Beecham Clinical Laboratories, Inc. SmithKline Labs, a
subsidiary of SmithKline Beecham, is one of the largest independent clinical
laboratories in the United States. SmithKline Beecham is a stockholder of
Healtheon and after the merger will own approximately 4.4% of Healtheon's common
stock. In December 1997, Healtheon and SmithKline Labs entered into a Services
Agreement, or the Services Agreement, under which Healtheon provides lab orders
and results to providers that use SCAN. SmithKline Labs has also agreed to
promote Healtheon as its preferred vendor for laboratory electronic connectivity
services.

     Healtheon acquired SCAN-related assets from SmithKline Labs, including
approximately 4,200 installed workstations in physicians' offices, hospitals and
other provider offices. Healtheon is currently developing Healtheon Dx, an
Internet-enabled version of the SCAN system, which Healtheon plans to integrate
into the Healtheon Platform and to offer to physicians using SmithKline Labs'
services or to physicians using other laboratories. Tadataka Yamada, M.D.,
Chairman Research and Development, Pharmaceuticals of SmithKline Beecham, is a
member of Healtheon's Board of Directors. The Services Agreement is effective
through December 2002, with options for successive two-year renewals, subject to
earlier termination in the event Healtheon fails to meet certain network
performance standards or if Healtheon otherwise breaches its material
obligations under the Services Agreement. The Services Agreement provides that
the parties will negotiate new rates as of January 1, 2001 and each two years
thereafter. Under the Services Agreement, the renegotiated rates must be
competitive with the marketplace and must be no higher than the lowest fees
charged by Healtheon to similarly situated customers.

     In December 1998, Healtheon agreed to purchase, and in January 1999,
Healtheon purchased certain assets used by SmithKline Labs to provide laboratory
results delivery services in exchange for $2.0 million in cash and approximately
1.8 million shares of Healtheon's common stock. Healtheon and SmithKline Labs
entered into a related services agreement under which Healtheon will provide
certain electronic laboratory results delivery services to approximately 20,000
provider sites, in addition to the sites currently served through the SCAN
service. The services agreement has a five year term.

     On February 9, 1999, SmithKline Beecham announced that it has agreed to
sell SmithKline Labs to Quest Diagnostics, Incorporated. SmithKline Labs has
been one of Healtheon's strategic partners since December 1997, and Healtheon's
relationship with them has been beneficial. Healtheon expects its agreements
with SmithKline Labs to remain in effect as a result of the acquisition by Quest
Diagnostics.

     Brown & Toland Physician Services Organization. Brown & Toland Medical
Group, or BTMG, based in San Francisco, California, is a partnership of
approximately 2,000 physicians representing a merger of physicians from
California Pacific Medical Center, the University of California-San Francisco
and Stanford University. Brown & Toland, a wholly owned subsidiary of BTMG, is
the management company that administers the managed care risk business on behalf
of BTMG and other physician organizations. In December 1997, Healtheon and Brown
& Toland entered into an agreement under which Healtheon is developing Healtheon
Practice, which Healtheon intends to market to Brown & Toland and other payers
and providers. Healtheon also manages the information technology operations of
Brown & Toland.
                                       150
<PAGE>   161

Through its relationship with Brown & Toland, Healtheon believes it is gaining
valuable industry-segment expertise from a leader in managed care and
accelerating its market presence in the San Francisco Bay Area. Healtheon's
agreement with Brown & Toland is effective through September 2000, although it
may be terminated by either party upon 120 days' notice.

     Beech Street Corporation. Beech Street is one of the largest PPOs in the
United States. Beech Street's PPO network consists of approximately 4,300
hospitals and 320,000 physician locations serving 15 million individuals in 49
states, and its clients consist of major self-insured employers, insurance
companies and third-party administrators. In December 1997, Healtheon and Beech
Street entered into an agreement under which Healtheon is developing Healtheon
ProviderWorks, which Healtheon intends to offer to Beech Street and to other
payers and providers. Healtheon also manages the information technology
operations of Beech Street. The relationship with Beech Street provides
Healtheon with important industry-segment expertise and a strategic entry-point
into the PPO market segment. Healtheon's agreement with Beech Street is
effective through December 2002, although it may be terminated by either party
upon 180 days' notice.

The Healtheon Platform

     The Healtheon Platform is a distributed application framework, combined
with software tools that ensure security, scalability, availability, reliability
and manageability, on which transaction intensive applications can be delivered
over the Internet or over other distributed environments. The Healtheon Platform
is deployed on a server complex at the Healtheon data center in Santa Clara,
California, which consists of SUN Solaris and Windows NT servers in a fault
tolerant configuration and redundant or fault tolerant network components. The
Healtheon Platform includes the following features:

     Security. The Healtheon Platform is designed to ensure the privacy and
integrity of data and communications by using a combination of security
methodologies to provide multiple lines of defense. All Internet communications
between Healtheon and its users employ the Secure Sockets Layer protocol. In
addition, Healtheon utilizes server digital certificates and username/password
schemes to authenticate users. Each user has a unique user ID and has one or
more roles that define the types of functionality and data access available. All
Healtheon's applications record logging information, creating an audit trail,
and protect privacy by encrypting sensitive data. Healtheon also uses a
multi-layered firewall complex to secure the Healtheon network infrastructure.
In addition, network vulnerability scanners are used on a regular basis to
actively monitor security status. Healtheon's physical security systems at its
Santa Clara facility consist of comprehensive physical controls and
multi-layered internal network and information system safeguards. The physical
controls include using fingerprint authentication, dual-level access points, and
multiple alarm systems.

     Scalability. The Healtheon Platform utilizes COBRA-based middleware, which
enables a highly scalable distributed applications infrastructure. The platform
enables an application to run simultaneously on multiple host systems, allowing
for large numbers of simultaneous users while at the same time optimizing
network performance and resource utilization. In addition, the Healtheon
Platform has been designed to transparently deploy new services and hardware
while existing applications remain operational. Finally, the Healtheon Platform
reduces communications bottlenecks resulting from limited numbers of connections
to database servers through intelligent management of database connections and
object caches that reduce the need to query database servers for frequently used
data.

     Rapid Application Development and Integration. The Healtheon Platform is
designed to enable rapid application development and integration. The platform
supports object-oriented programming, which accelerates the design process
through object reuse. Healtheon maintains a comprehensive set of object
libraries, called core services, that allows developers to build complex
applications rapidly. The platform is also designed for deploying applications
developed by third parties with relative ease. The platform interfaces with
legacy systems by accepting industry standard ANSI X.12 and HL7 electronic data
interchange formats.

                                       151
<PAGE>   162

     High Availability. The Healtheon Platform architecture is designed to
ensure high availability through the replication of applications and other
software services, failure detection and automatic restart of failed services
and applications. Running multiple copies of a service or application removes
any single point of failure within the system and ensures that at least some
copies of a service will be available while others may have failed. In addition,
the servers that host Healtheon applications are duplicated to provide
redundancy. Healtheon uses duplicate fiber optic cable connections to Sprint and
WorldCom to ensure highly-available access to the Internet. Healtheon's platform
uses a mix of fault-tolerant hardware, redundant equipment and back-up power
systems.

     Manageability. The Healtheon management framework provides a single image
view of all Healtheon services, thus simplifying administration in a distributed
environment. Healtheon services can be managed from a Web-based management
station. The Healtheon management and administration framework monitors service
performance and generates event notifications of system abnormalities.

     Disaster Recovery Plans. Although Healtheon believes its operations
facilities are highly resistant to systems failure and sabotage, it has
developed, and is in the process of implementing, a disaster recovery and
contingency operations plan. In addition, all of Healtheon's services are linked
to advanced storage systems that provide data protection through techniques such
as replication. Healtheon also maintains on-site backup power systems.

     Audits. Healtheon's information technology department periodically
performs, and retains accredited third parties to perform, audits of its
operational procedures under both internally-developed audit procedures and
externally-recognized standards.

Customer Support

     Healtheon believes that a high level of customer support is necessary to
achieve wide acceptance of its solution. Healtheon provides a wide range of
customer support services through a staff of customer service personnel,
multiple call centers and an e-mail help desk. Healtheon also offers Web-based
support services that are available 24 hours a day, seven days a week and are
frequently updated to improve existing information and to support new services.
Healtheon also employs technical support personnel who work directly with its
direct sales force, distributors and customers of its applications and services.
Healtheon provides its customers with the ability to purchase maintenance for
its applications and services, which includes technical support and upgrades.
Healtheon also provides training programs for its customers. As of March 31,
1999, Healtheon had 275 employees and independent contractors in customer
support functions, including network services, provider services and customer
support services.

Sales and Marketing

     Healtheon's direct sales force targets significant potential customers in
each market segment by region. In certain instances, Healtheon's direct sales
force works with complementary brokers, value added resellers and systems
integrators to deliver complete solutions for major customers. In addition,
senior management plays an active role in the sales process by cultivating
industry contacts. Healtheon markets its applications and services through
direct sales contacts, strategic relationships, the sales and marketing
organizations of its strategic partners, participation in trade shows, articles
in industry publications and by leveraging its existing client base. Healtheon
attends a number of major trade shows each year and has begun to sponsor
executive conferences, which feature industry experts who address the
information systems needs of large healthcare organizations. Healtheon supports
its sales force with technical personnel who perform demonstrations of
Healtheon's applications and assist clients in determining the proper hardware
and software configurations. Healtheon's executive sales and marketing
management is located in its Santa Clara, California headquarters and in its
Atlanta, Georgia, Minneapolis, Minnesota and San Francisco, California
facilities, while its account representatives are deployed across the United
States. As of March 31, 1999, Healtheon employed 140 sales executives, account
managers, direct sales representatives and sales support personnel.

                                       152
<PAGE>   163

Development and Engineering

     Healtheon believes that its future success will depend in large part on its
ability to continue to maintain and enhance its platform, applications and
services. To this end, Healtheon leverages the modular nature of its platform
architecture to enable it to develop new applications and services rapidly.
Healtheon has developed applications and services both independently and through
acquisitions. Healtheon will continue to work closely with other companies in
its applications development efforts.

     Healtheon has several significant projects currently in development. These
include the continued enhancement of the platform architecture, development of
new services such as Healtheon Practice, Healtheon ProviderWorks and Healtheon
Dx, and integration of ActaMed's platform, network and associated services. As
of March 31, 1999, Healtheon employed 270 people in the areas of applications
design, research and development, quality assurance and technical support.

     Healtheon's development and engineering expense, which excludes development
expenses included in cost of operations, totaled $19.0 million in 1998, $12.3
million in 1997, $8.3 million in 1996, $7.0 million in the three months ended
March 31, 1999 and $3.7 million in the three months ended March 31, 1998.
Healtheon believes that timely development of new and enhanced applications and
technology is necessary to remain competitive in the marketplace. Accordingly,
Healtheon intends to continue recruiting and hiring experienced development
personnel and to make other investments in development and engineering.

     The emerging market for healthcare information exchange and transaction
processing is characterized by rapid technological developments, frequent new
application introductions and evolving industry standards. The emerging nature
of this market and its rapid evolution will require that Healtheon continually
improve the performance, features and reliability of its applications and
services, particularly in response to competing offerings, and that it introduce
new applications and services or enhancements to existing applications and
services as quickly as possible and prior to its competitors. The success of new
application and service introductions is dependent on several factors, including
proper definition of new applications or services, timely completion and
introduction of new applications and services, differentiation of new
applications and services from those of Healtheon's competitors and market
acceptance. There can be no assurance that Healtheon will be successful in
developing and marketing new applications and services that respond to
competitive and technological developments and changing customer needs. The
failure of Healtheon to develop and introduce new applications and services
successfully on a timely basis and to achieve market acceptance for its
applications and services could have a material adverse effect on Healtheon's
business, financial condition and results of operations. In addition, the
widespread adoption of new Internet, networking or telecommunication
technologies or standards or other technological changes could render its
applications and services obsolete or require substantial expenditures by
Healtheon to adapt its applications and services. Moreover, there is a risk that
a competitor's product might become the standard for healthcare information
services.

Intellectual Property

     Healtheon relies upon a combination of trade secret, copyright and
trademark laws, license agreements, confidentiality procedures, employee
nondisclosure agreements and technical measures to maintain the secrecy of its
intellectual property. Healtheon believes that patent, trade secret and
copyright protection are less significant to Healtheon's success than its
ability to further develop applications. Healtheon has several trademarks in the
United States and internationally.

Competition

     The market for healthcare information services is intensely competitive,
rapidly evolving and subject to rapid technological change. Many of Healtheon's
actual and potential competitors have announced or introduced Internet
strategies. Healtheon's competitors can be divided into several groups:
healthcare information software vendors, including HBO & Company, which was
recently acquired by McKesson Corporation, one of the country's largest drug
wholesalers, and Shared Medical Systems Corporation; healthcare electronic data
interchange companies, including ENVOY Corporation, which was recently
                                       153
<PAGE>   164

acquired by Quintiles Transnational Corp., and National Data Corporation; and
large information technology consulting service providers, including Andersen
Consulting, International Business Machines Corporation and Electronic Data
Systems Corporation. Each of these companies can be expected to compete with
Healtheon within certain segments of the healthcare information technology
market. Furthermore, major software information systems companies and others,
including those specializing in the healthcare industry that are not presently
offering applications that compete with those offered by Healtheon, may enter
Healtheon's markets. In some cases, large customers may have the ability to
compete directly with Healtheon as well. Healtheon also competes with smaller
regional competitors. Many of Healtheon's competitors and potential competitors
have significantly greater financial, technical, product development, marketing
and other resources and greater market recognition than Healtheon. Many of
Healtheon's competitors also currently have, or may develop or acquire,
substantial installed customer bases in the healthcare industry. As a result of
these factors, Healtheon's competitors may be able to respond more quickly to
new or emerging technologies and changes in customer requirements or to devote
greater resources to the development, promotion and sale of their applications
or services than Healtheon. There can be no assurance that Healtheon will be
able to compete successfully against current and future competitors or that
competitive pressures faced by Healtheon will not materially adversely affect
its business, financial condition and results of operations.

Employees

     As of March 31, 1999, Healtheon had a total of 725 employees and
independent contractors, of whom there were 275 in customer, network and
provider services, 270 in development and engineering, 140 in sales and
marketing and 40 in corporate finance and administration. None of Healtheon's
employees is represented by a labor union, and Healtheon has never experienced a
work stoppage. Healtheon believes its relationship with its employees to be
good. Healtheon's ability to achieve its financial and operational objectives
depends in large part upon its continuing ability to attract, integrate, retain
and motivate highly qualified sales, technical and managerial personnel, and
upon the continued service of its senior management and key sales and technical
personnel, most of whom are not bound by an employment agreement. Competition
for such qualified personnel in Healtheon's industry and geographical location
in the San Francisco Bay Area is intense, particularly in software development
and technical personnel.

Properties

     Healtheon's principal executive and corporate offices and development and
network operations are located in Santa Clara, California, in approximately
50,000 square feet of leased office space under a lease that expires in March
2008. Healtheon also maintains sales, development and network operations in
Atlanta, Georgia, in approximately 41,000 square feet of leased office space
under a lease that expires in July 2001; sales, engineering and support
operations in Minneapolis, Minnesota, in approximately 16,500 square feet of
leased office space under a lease that expires in December 1999; and sales,
engineering and support operations in San Francisco, California, in
approximately 11,000 square feet of leased office space under two leases that
expire in November 2000 and September 2001. Healtheon believes that its
facilities are adequate for its current operations and that additional leased
space can be obtained if needed.

Legal Proceedings

     To date, Healtheon has not been subject to any material litigation.

      MARKET FOR HEALTHEON'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

     Healtheon completed the initial public offering of its common stock on
February 10, 1999. Healtheon's common stock has been traded on the Nasdaq
National Market under the symbol "HLTH" since February 11, 1999. Prior to that
date, there was no public market for our common stock and, therefore, no quoted
market prices for our common stock are available for the years ended December
31,

                                       154

1998 and 1997. The following table lists quarterly information on the price
range of Healtheon common stock based on the high and low reported closing bid
prices for Healtheon common stock as reported on the Nasdaq Stock Market for the
periods indicated below:

<TABLE>

  First Quarter.............................................  $49.38    $21.75
  Second Quarter (through [  ] 1999)........................    [  ]      [  ]
</TABLE>

     On February 28, 1999, there were 373 holders of record of our common stock.
Because many of such shares are held by brokers and other institutions on behalf
of stockholders, we are unable to estimate the total number of stockholders
represented by these record holders.

     The market price of Healtheon's common stock has fluctuated since the date
of its initial public offering and is likely to fluctuate in the future. Factors
that may have a significant effect on the market price of our common stock
include:

     - actual or anticipated quarterly variations in our operating results;

     - changes in expectations of future financial performance or changes in
       estimates of securities analysts;

     - announcements of technological innovations;

     - announcements relating to strategic relationships;

     - customer relationship developments; and

     - conditions affecting the Internet or healthcare industries, in general.

     The trading price of Healtheon's common stock may be volatile. The stock
market in general, and the market for technology and Internet-related companies
in particular, has experienced extreme volatility that often has been unrelated
to the operating performance of particular companies. These broad market and
industry fluctuations many adversely affect the trading price of Healtheon's
common stock, regardless of Healtheon's actual operating performance.

     In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted. If this were to happen to Healtheon, litigation would be expensive
and would divert management's attention.

     Healtheon has never declared or paid any cash dividends on our common stock
or other securities and does not anticipate paying cash dividends in the
foreseeable future.

                 HEALTHEON SELECTED CONSOLIDATED FINANCIAL DATA

     The following selected consolidated financial data of Healtheon should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and with the consolidated financial
statements and notes thereto, which are included elsewhere in this proxy
statement/ prospectus. In May 1998, Healtheon acquired ActaMed in a transaction
accounted for as a pooling of interests. All financial information has been
restated to reflect the combined operations of Healtheon and ActaMed. The
consolidated statements of operations data for the three-year period ended
December 31, 1998 and the consolidated balance sheet data at December 31, 1998
and 1997 are derived from, and are qualified by reference to, the audited
consolidated financial statements included elsewhere in this proxy
statement/prospectus. The consolidated statements of operations data for the
two-year period ended December 31, 1995 and the consolidated balance sheet data
at December 31, 1996, 1995 and 1994 are derived from, and are qualified by
reference to, audited consolidated financial statements that are not included in
this proxy statement/prospectus. The consolidated statements of operations and
balance sheet data as of and for the years ended December 31, 1995 and 1994 are
derived solely from the ActaMed statements of operations and balance sheets for
such periods because Healtheon did not commence operations until January 1996.
See notes 1 and 2 of notes to consolidated financial statements for a discussion
of the accounting for the acquisition of ActaMed. The statement of operations
data for the three-month periods ended March 31, 1999 and 1998 and the balance
sheet data as of March 31, 1999 are derived from unaudited financial statements
included elsewhere in this proxy statement/prospectus and, in the opinion of
Healtheon's management, include all adjustments, consisting only of normal
recurring adjustments, which are necessary for a fair presentation of the
results of operations for these periods. Historical operating results are not
necessarily indicative of results in the future, and the results for interim
periods are not necessarily indicative of the results that may be expected for
the entire year. See note 1 of notes to consolidated financial statements for an
explanation of the determination of the shares used in computing basic and
diluted net loss per common share.

                 HEALTHEON MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     You should read the following discussion in conjunction with Healtheon's
consolidated financial statements and notes thereto. The following discussion
contains forward-looking statements that involve risks and uncertainties.
Healtheon's actual results could differ materially from the results contemplated
by these forward-looking statements as a result of certain factors discussed
below in "Risk Factors" and elsewhere in this proxy statement/prospectus.

OVERVIEW

     Healtheon is pioneering the use of the Internet to simplify workflows,
decrease costs and improve the quality of patient care throughout the healthcare
industry. Healtheon's Virtual Healthcare Network, or VHN, solution enables the
secure exchange of information among a wide array of disparate healthcare
information systems and provides a framework for a broad range of healthcare
transactions.

     Healtheon was incorporated in December 1995, commenced operations in
January 1996 and until late 1997 had not recognized substantial revenue and was
therefore considered to be in the development stage. In May 1998, Healtheon
acquired ActaMed, which was incorporated in 1992. The acquisition of ActaMed was
accounted for as a pooling of interests. The financial information presented
reflects the combined financial position and results of operations of Healtheon
and ActaMed for all dates and periods presented. Healtheon's revenue to date has
been derived primarily from proprietary non-Internet network services offered by
ActaMed and from management and operation of customers' information technology,
or IT, infrastructure. In March 1996, ActaMed acquired EDI Services, or EDI, a
wholly-owned subsidiary of UnitedHealth Group, in a transaction accounted for as
a purchase. Accordingly, the operations of EDI are included in Healtheon's
consolidated statements of operations beginning in March 1996. In August 1998,
Healtheon acquired substantially all of the assets of Metis, LLC, a leading
consulting, design and development firm focused on Internet and intranet-based
solutions for medical centers and integrated delivery networks. In connection
with this acquisition, Healtheon issued 1,600,000 shares of its common stock, of
which 200,000 shares are held in escrow to secure certain indemnification
obligations. Of the total shares issued, 476,548 shares were issued to certain
employees under restricted stock purchase agreements subject to a lapsing right
of repurchase, at Healtheon's option, over the agreements' respective vesting
periods. The Metis acquisition was treated as a tax-free reorganization and was
accounted for as a purchase.

     Because Healtheon has recently begun operations, it is difficult to
evaluate its business and prospects. Healtheon's revenue and income potential is
unproven and its business model is still emerging. Healtheon's historical
financial information is of limited value in projecting its future operating
results because of its limited operating history as a combined organization and
the emerging nature of its markets. Healtheon began operations in January 1996
and until recently had not earned significant revenue. Healtheon has lost money
since it began operations and, as of March 31, 1999, it had an accumulated
deficit of $122.0 million. Healtheon plans to invest heavily in acquisitions,
infrastructure development, applications development and sales and marketing. As
a result, Healtheon expects that it will continue to lose money through 1999 and
it may never achieve or sustain profitability.

     Healtheon has developed strategic relationships with healthcare industry
leaders, including UnitedHealth Group, SmithKline Labs, Brown & Toland and Beech
Street. These four companies each accounted for over 10% of Healtheon's total
revenue in 1998 and the first quarter of 1999, and together accounted for
approximately 87% of Healtheon's total revenue in 1998. Healtheon expects that a
small number of customers will continue to account for a substantial portion of
its revenue for the foreseeable future. The loss of one or more of Healtheon's
significant customers, or a decline in the volume of business generated by these
customers, could have a material adverse effect on Healtheon's business,
financial condition and results of operations.

     Cost of operations consist of costs related to services Healtheon provides
to customers and costs associated with the operation and maintenance of its
networks. These costs include salaries and related

                                       157
<PAGE>   168

expenses for consulting and development personnel, network operations personnel
and customer support personnel; telecommunication costs; maintenance of network
equipment; amortization of certain intangible assets; a portion of facilities
expenses; and leased personnel and facilities costs. Given Healtheon's limited
operating history, changes in revenue mix, limited history of Internet-based
network services, recent investments in personnel, amortization of
infrastructure investments and evolving business model, Healtheon believes that
analysis of historical cost of operations as a percentage of revenue is not
meaningful. Healtheon anticipates that its total cost of operations will
increase in absolute dollars in the future.

     Development and engineering expense, which excludes development expenses
that are included in cost of operations, consists primarily of salaries and
related expenses associated with the development of applications and services.
Expenses include compensation paid to engineering personnel, fees to outside
contractors and consultants, a portion of facilities expenses and the
maintenance of capital equipment used in the development process. Healtheon
believes its success is partially dependent upon its ability to introduce new
applications in several healthcare markets in a relatively short period of time.
Accordingly, Healtheon intends to continue recruiting and hiring experienced
engineering personnel and to continue making other investments in development
and engineering. Healtheon expects that development and engineering expenses
will continue to increase in absolute dollars. Currently, all development and
engineering expenses are expensed as incurred.

     Sales, general and administrative expense consists primarily of salaries
and related expenses for sales, account management, marketing, administrative,
finance, legal, human resources and executive personnel; commissions; costs and
expenses for marketing programs and trade shows; fees for professional services;
and costs of accounting and internal control systems to support Healtheon's
operations. Healtheon anticipates that sales, general and administrative expense
will continue to increase in absolute dollars as it adds sales, marketing and
administrative personnel, increases its marketing and promotional activities and
incurs costs related to being a public company, such as directors' and officers'
liability insurance premiums and professional fees.

Three Months Ended March 31, 1999 and 1998

     Revenue. Healtheon earns revenue from services which include providing
access to its network-based services, including fixed fee and transaction based
services, and performing development and consulting services, and from licensing
software. Services revenue also includes revenue from the management and
operation of customers' IT infrastructure. Customers may purchase some or all of
Healtheon's applications and services and the customer relationship may evolve
from utilizing development and consulting services to utilizing transaction and
subscription-based services. Healtheon earns network-based services revenue from
fixed fee subscription arrangements, which revenue is recognized ratably over
the term of the applicable agreement, and from arrangements that are priced on a
per-transaction or per-user basis, which revenue is recognized as the services
are performed. Revenue from development projects is recognized on a
percentage-of-completion basis or as the services are performed, depending on
the terms of the contract. Revenue from consulting services and revenue from the
management and operation of customers' IT infrastructure is recognized as the
services are performed. Cash received in excess of revenue recognized relating
to these services has been recorded as deferred revenue. At March 31, 1999,
Healtheon had deferred revenue of approximately $3.6 million.

     Total revenue increased to $17.6 million in the first quarter of 1999 from
$9.8 million in the first quarter of 1998. Revenue from the Service Agreements
with UnitedHealth and SmithKline Labs increased to $9.5 million from the first
quarter of 1999 from $4.7 million in the first quarter of 1998. Increased
transaction based services under the UnitedHealth Group Agreement, and
additional revenue from the

                                       159
<PAGE>   170

January 1999 Services Agreement with SmithKline Labs, which was phased in during
the first quarter of 1999 contributed to the significant increases in revenue.

     In addition, Healtheon's revenue increased due to contracts with new
customers and increased revenue from existing customers, Brown & Toland and
Beech Street. Healtheon recognized revenue for IT services of $4.9 million in
the first quarter of 1999 and $3.8 million in the first quarter of 1998. In
addition, Healtheon recognized revenue related to IT development services of
$0.5 million in the 1999 period and $0.8 million in the 1998 period.

     The UnitedHealth Group Agreement has a five-year term. However, the
agreement provides that two years after the date of the agreement, which was
signed on April 4, 1996, the parties will agree on new prices that are
competitive with the marketplace. Healtheon and UnitedHealth Group are
negotiating the new prices and Healtheon anticipates that the new prices will
reduce the rates paid by UnitedHealth Group, on a prospective basis. The
Services Agreements with SmithKline Labs also each have a five-year term.
However, the December 1997 Services Agreement provides that the parties will
negotiate new rates as of January 1, 2001 and every two years thereafter. Under
the terms of the Services Agreement, the renegotiated rates must be competitive
with the marketplace and must be no higher than the lowest fees charged by
Healtheon to similar customers.

     Cost of Operations. Cost of operations was $15.5 million in the first
quarter of 1999 and $7.5 million in the first quarter of 1998. These increases
resulted mainly from higher personnel and network operation costs required to
support these increased service revenues.

     Development and Engineering. Development and engineering expense was $7.0
million in the first quarter of 1999 and $3.7 million in the first quarter of
1998. The increase was the result of a significant increase in the number of
engineers engaged in the development of Healtheon's applications and services.

     Sales, General and Administrative. Sales, general and administrative
expense increased to $8.9 million in the first quarter of 1999 from $4.7 million
in the first quarter of 1998. The amortization of deferred stock compensation
expense increased by $1.6 million. The remainder of the increase resulted from
salaries and related costs of added sales personnel and executive management.

     Deferred stock compensation represents the difference between the purchase
or exercise price of certain restricted stock and stock option grants and the
deemed fair value of Healtheon's common stock at the time of those grants.
Healtheon recorded deferred stock compensation of $6.3 million in the first
quarter of 1999, $8.2 million in the full year of 1998 and $2.7 million in the
full year of 1997. The deferred stock compensation balance at March 31, 1999 was
$11.1 million. The deferred stock compensation balance is being amortized based
on a graded vesting method over the vesting period, generally four years, of the
option or restricted stock grants. Amortization is estimated to total $7.8
million in 1999, $3.5 million in 2000, $1.5 million in 2001 and $.4 million for
2002.

     Depreciation and amortization. Depreciation and amortization was $5.2
million in the first quarter of 1999 and $2.8 million in the first quarter of
1998. Property and equipment is being depreciated over the estimated useful life
of the related assets, generally three to seven years. All of the intangible
assets are being amortized over expected lives of three to five years. The
increase is due primarily to the technology rights acquired with the January
1999 Services Agreement with SmithKline Labs and the acquisition of Metis LLC in
August 1998, as well as the increase in property and equipment to support
overall growth. Amortization charges are estimated to be $11.8 million in 1999,
$10.0 million in 2000, $3.4 million in 2001, $1.8 million in both 2002 and 2003
and $.2 million in 2004 assuming no impairment of the remaining unamortized
intangible asset balances and no additional acquisitions of intangible assets.

     Interest Income and Expense. Interest income has been derived primarily
from cash investments. Interest expense results primarily from Healtheon's
borrowings and from capitalized lease obligations for equipment purchases. Net
interest income was $0.6 million in the first quarter of 1999 and $0.2 million
in the first quarter of 1998. The increase for the 1999 period was due to higher
average cash balances resulting from the proceeds of Healtheon's $46.1 million
preferred stock financing in October 1998 and the net proceeds of $41.4 million
from Healtheon's initial public offering in February 1999.

     Dividends on ActaMed's Convertible Redeemable Preferred Stock. Healtheon
acquired ActaMed in a transaction accounted for as a pooling-of-interests in May
1998. Because dividends on ActaMed's convertible redeemable preferred stock were
cumulative whether declared or not, ActaMed accrued the dividends on a quarterly
basis. Dividends of $.9 million were charged against income in the consolidated
statements of operations in the first quarter of 1998. None of the dividends
were paid, and, in conjunction with approving the acquisition of ActaMed by
Healtheon, ActaMed's preferred stockholders waived their right to receive the
dividends, which totaled $7.5 million at the time of the acquisition. The
ActaMed preferred stockholders received an aggregate of 17.3 million shares of
Healtheon common stock in exchange for their ActaMed convertible redeemable
preferred stock.

Years Ended December 31, 1998, 1997 and 1996

     Revenue. Healtheon earns revenue from services and services to related
parties, both of which include providing access to its network-based services,
including fixed fee and transaction based services, and performing development
and consulting services, and from licensing software. Services revenue also
includes revenue from the management and operation of customers' IT
infrastructure. Customers may purchase some or all of Healtheon's applications
and services and the customer relationship may evolve from utilizing development
and consulting services to utilizing transaction and subscription-based
services. Healtheon earns network-based services revenue from fixed fee
subscription arrangements, which revenue is recognized ratably over the term of
the applicable agreement, and from arrangements that are priced on a
per-transaction or per-user basis, which revenue is recognized as the services
are performed. Revenue from development projects is recognized on a
percentage-of-completion basis or as the services are performed, depending on
the terms of the contract. Revenue from consulting services and revenue from the
management and operation of customers' IT infrastructure is recognized as the
services are performed. Cash received in excess of revenue recognized relating
to these services has been recorded as deferred revenue. At December 31, 1998,
Healtheon had deferred revenue of approximately $1.9 million.

     Total revenue increased to $48.8 million in 1998 from $13.4 million in 1997
and $11.0 million in 1996. Revenue from services was $27.1 million in 1998, $4.3
million in 1997 and $1.8 million in 1996. The significant increase in services
revenue in these periods was principally due to new contracts with Brown &
Toland Physician Services Organization, or Brown & Toland, and Beech Street
Corporation, or Beech Street, for the management and operation of their IT
infrastructure beginning in late 1997. To provide these services, Healtheon
utilizes its own personnel, certain outside contractors and certain personnel
and facilities of the customers that are leased to Healtheon. The cost of these
leased customer personnel and facilities are included as part of the total costs
of the IT and development services that Healtheon billed to the customers.
Healtheon recognized revenue for IT services of $15.1 million in 1998 and $2.1
million in 1997. Revenue for IT services included costs of leased personnel and
facilities of $11.8 million in 1998 and $1.9 million in 1997. These amounts are
also included in cost of services. In addition, Healtheon recognized revenue
related to development services of $6.5 million in 1998 and $.2 million in 1997.
No revenue was recognized from IT services or development services in 1996.

     Revenue from services to related parties consists of services provided to
UnitedHealth Group under a Services and License Agreement between ActaMed and
UnitedHealth Group dated April 4, 1996, or the UnitedHealth Group Agreement, and
services provided to SmithKline Beecham Clinical Laboratories, Inc., or
SmithKline Labs, under a Services Agreement between ActaMed and SmithKline Labs
dated December 31, 1997, or the Services Agreement. Revenue from services to
related parties increased to $21.0 million in 1998 from $7.3 million in 1997 and
$4.2 million in 1996. The increase was primarily due to the additional revenue
from the December 1997 Services Agreement with SmithKline Labs to service its
SCAN laboratory and test order and results service.

     ActaMed entered into a national marketing and licensing agreement, or the
Agreement, with International Business Machines Corporation in 1995 that granted
IBM a nonexclusive, nontransferable right to market ActaMed's software and
services for a total of $6.3 million. Under the Agreement, Healtheon recognized
software license revenue of approximately $1.2 million in 1997 and approximately

                                       161
<PAGE>   172

$3.4 million in 1996, upon delivery of the software. All revenue under the
Agreement had been recognized by the end of 1997.

     In December 1996, ActaMed entered into a new agreement, or the License, to
license its newly granted patent to IBM. As part of the License, IBM agreed to
pay $4.8 million over a four-year period, $1.0 million in December 1996 and the
remaining balance in 48 equal monthly installments commencing in January 1997.
Additionally, in conjunction with the License, IBM was issued a five-year
warrant to purchase 282,522 shares of common stock at a price of $7.97 per
share. Because of the extended payment terms and ActaMed's contentious
relationship with IBM, ActaMed concluded that the license fee was not assured of
collection and, accordingly, Healtheon is recognizing this revenue as the
proceeds are collected. Healtheon recognized revenue from the License of $.8
million in 1998, $.8 million in 1997 and $1.0 million in 1996. Deferred revenue
at December 31, 1998 included $1.6 million related to the License. Healtheon
does not expect that it will earn a material amount of revenue from software
licenses in the foreseeable future.

     Cost of Operations. Total cost of operations was $43.0 million in 1998,
$10.4 million in 1997 and $6.7 million in 1996. Cost of services increased to
$26.9 million in 1998 from $3.9 million in 1997 and $1.6 million in 1996. The
increases included costs of leased personnel and facilities utilized to provide
IT services totaling $11.8 million in 1998 and $1.9 million in 1997 as well as
costs related to development services of $6.5 million in 1998 and $.2 million in
1997. The remainder of the increase resulted from increased personnel and
expansion of Healtheon's network infrastructure to support current customers and
future business activities. Healtheon believes that its margin on services
revenue will continue to be negative until revenue from other than IT and
development services increases.

     Cost of services to related parties was $16.1 million in 1998, $6.5 million
in 1997 and $4.9 million in 1996. These increases resulted from higher personnel
and network operation costs required to support increased transactions from
Healtheon's SCAN services under the Services Agreement with SmithKline Labs as
well as increased transaction volume under the UnitedHealth Group Agreement.

     Development and Engineering. Development and engineering expense was $19.0
million in 1998, $12.3 million in 1997 and $8.3 million in 1996. The increase
was the result of a significant increase in the number of engineers engaged in
the development of Healtheon's applications and services.

     Sales, General and Administrative. Sales, general and administrative
expense increased to $23.1 million in 1998 from $10.1 million in 1997 and $8.4
million in 1996. The amortization of deferred stock compensation expense
accounted for $2.8 million of the increase in 1998 and $.6 million of the
increase in 1997. In addition, 1998 includes $.8 million of costs related to the
merger with ActaMed. Substantially all of the remainder of the increase in both
1998 and 1997 resulted from salaries and related support costs for added sales
personnel and executive management.

     Deferred stock compensation represents the difference between the purchase
or exercise price of certain restricted stock and stock option grants and the
deemed fair value of Healtheon's common stock at the time of those grants.
Healtheon recorded deferred stock compensation of $8.2 million in 1998 and $2.7
million in 1997. The deferred stock compensation balance at December 31, 1998
was $6.9 million. From January 1, 1999 through February 10, 1999, the date of
Healtheon's initial public offering, Healtheon granted additional stock options
for which it recorded approximately $6.3 million of additional deferred stock
compensation. The deferred stock compensation balance will be amortized based on
a graded vesting method over the vesting period, generally four years, of the
option or restricted stock grants. Amortization is estimated to total $7.8
million for 1999, $3.5 million for 2000, $1.5 million for 2001 and $.4 million
for 2002.

     Depreciation and amortization. Depreciation and amortization of intangible
assets was $16.1 million in 1998, $6.0 million in 1997 and $4.2 million in 1996.
The intangible assets include those arising from the acquisitions of EDI from
UnitedHealth Group in March 1996 and of Metis in August 1998 as well as certain
intangible assets related to the technology rights acquired related to the SCAN
Services Agreement with SmithKline Labs in December 1997. Property and equipment
is being depreciated over

                                       162
<PAGE>   173

the estimated useful life of the related assets, generally three to seven years,
while the intangible assets are generally being amortized over a three-year
life. Although the Services and License Agreement entered into with UnitedHealth
Group in connection with the acquisition of EDI has a five year term, Healtheon
determined that a three year amortization period was appropriate for the
EDI-related assets due to the price renegotiation required by such agreement,
the probability that the purchased technology and software would be replaced
within three years and the uncertain profitability of the agreement after the
price renegotiation. Similarly, although the Services Agreement entered into
with SmithKline Labs in connection with the acquisition of the SCAN-related
assets has a five year term, Healtheon determined that a three year amortization
period was appropriate for the SCAN related assets due to the price
renegotiation required by such agreement, the probability that the purchased
technology and software would be replaced within three years and the uncertain
profitability of the agreement after the price renegotiation. There can be no
assurance that Healtheon's services to UnitedHealth Group and SmithKline Labs
will be profitable after the price renegotiations required by the agreements,
particularly given the uncertainty of future rates and volumes under those
agreements. At December 31, 1998, a total of $19.9 million remained to be
amortized. Amortization charges are estimated to be $10.1 million in 1999 and
$8.2 million in 2000, assuming no impairment of the remaining unamortized
intangible asset balances. See Notes 2 and 3 of Notes to Consolidated Financial
Statements.

     Write-off of Offering Costs. In October 1998, Healtheon withdrew a planned
initial public offering and wrote off the accumulated costs related to the
planned offering. These costs consisted primarily of professional fees for legal
and accounting services and printing costs.

     Interest Income and Expense. Interest income has been derived primarily
from the investment of excess cash. Interest expense results primarily from
Healtheon's borrowings and from capitalized lease obligations for equipment
purchases. Net interest income was $.8 million in 1998, $.3 million in 1997 and
$.5 million in 1996. The 1998 increase was due to higher average cash balances
resulting from the proceeds of Healtheon's $25.0 million preferred stock
financing in October 1997 and its $46.1 million preferred stock financing in
October 1998. Healtheon expects that net interest income may increase in the
near term as the proceeds of its initial public offering in February 1999 are
invested.

     Dividends on ActaMed's Convertible Redeemable Preferred Stock. Because
dividends on ActaMed's convertible redeemable preferred stock were cumulative
whether declared or not, ActaMed accrued the dividends on a quarterly basis.
Dividends of $.9 million in 1998, $2.9 million in 1997 and $2.5 million in 1996
were charged against income in the consolidated statements of operations. None
of the dividends were paid, and, in conjunction with approving the acquisition
of ActaMed by Healtheon, ActaMed's preferred stockholders waived their right to
receive the dividends, which totaled $7.5 million at the time of the
acquisition. The ActaMed preferred stockholders received an aggregate of 17.3
million shares of Healtheon common stock in exchange for their ActaMed
convertible redeemable preferred stock.

     Income Taxes. At December 31, 1998, Healtheon had net operating loss
carryforwards for federal income tax purposes of approximately $76.5 million and
federal tax credits of approximately $1.8 million, both expiring from 2009
through 2018. Of these net operating losses, approximately $19.9 million relates
to a consolidated subsidiary. This loss carryforward is available only to offset
future taxable income of that subsidiary. Because of the "change of ownership"
provisions of the Internal Revenue Code, a portion of Healtheon's net operating
loss carryforwards and tax credit carryforwards may be subject to an annual
limitation regarding their utilization against taxable income in future periods.
Thus, a portion of these carryforwards may expire before becoming available to
reduce future income tax liabilities.

LIQUIDITY AND CAPITAL RESOURCES

     In February 1999, Healtheon completed the initial public offering of its
common stock and realized net proceeds from the offering of approximately $41.4
million. Prior to the offering, Healtheon had funded its operations since
inception primarily through the private placement of equity securities, through
which it had raised net proceeds of $106.2 million through December 31, 1998.
Healtheon had also financed its operations through equipment lease financing and
bank borrowings. As of March 31, 1999, Healtheon had

                                       163
<PAGE>   174

outstanding equipment lease liabilities of $5.5 million and borrowings against a
line of credit of $1.1 million. As of March 31, 1999, Healtheon had
approximately $63.2 million of cash, cash equivalents and short-term
investments.

     Cash used in operating activities was $11.3 million in the first quarter of
1999 and $3.0 million in the first quarter of 1998. The cash used during these
periods was primarily attributable to net losses of $18.6 million in the first
quarter of 1999 and $9.7 million in the first quarter of 1998. The net losses
were offset in part by depreciation and amortization. Cash used in operating
activities was $27.0 million in 1998, $16.4 million in 1997 and $9.6 million in
1996. The cash used during these periods was primarily attributable to net
losses of $54.0 million in 1998, $28.0 million in 1997 and $18.6 million in 1996
offset in part by depreciation and amortization and dividends on ActaMed's
convertible redeemable preferred stock. Healtheon's losses were principally
related to increased development and engineering expenses and sales, general and
administrative expenses.

     Investments in property and equipment, excluding equipment acquired under
capital leases or through the issuance of common stock, were $4.0 million in the
first quarter of 1999 and $2.0 million in the first quarter of 1998. In the
first quarter of 1999, Healtheon used $15.1 million of cash to purchase
short-term investments and realized $7.8 million in cash from maturities of its
short-term investments. In the first quarter of 1998, Healtheon used $3.1
million of cash to purchase short-term investments and realized $7.1 million in
cash from maturities of its short-term investments. Investments in property and
equipment, excluding equipment acquired under capital leases, and internally
developed software were $6.3 million in 1998, $2.8 million in 1997 and $2.0
million in 1996. In 1997, Healtheon used $5.3 million of cash to purchase
short-term investments. In 1998, Healtheon purchased an additional $22.5 million
of short-term investments and realized $10.4 million in cash from maturities of
its short-term investments. Healtheon had no purchases or maturities of
short-term investments in 1996.

     Cash provided by financing activities was $40.9 million in the first
quarter of 1999, primarily from the net proceeds of Healtheon's initial public
offering of $41.4 million, as well as proceeds from exercises of employee stock
options, offset slightly by payments totaling $.9 million on capital lease
obligations and line of credit borrowings. Financing activities used $.1 million
of cash in the first quarter of 1998, resulting primarily from payments of
capital lease obligations. Cash provided by financing activities was $49.0
million in 1998, $34.6 million in 1997 and $11.1 million in 1996, resulting
primarily from net proceeds from the sale of preferred stock and, to a lesser
extent, from a bank line and bridge note financing in 1997. In addition,
proceeds from the issuance of common stock in 1998 totaled $3.7 million.

     As of March 31, 1999, Healtheon did not have any material commitments for
capital expenditures. Healtheon's principal commitments at March 31, 1999
consisted of obligations under operating and capital leases and line of credit
borrowings.

     Healtheon currently anticipates that its available cash resources and
credit facilities, will be sufficient to meet its presently anticipated working
capital, capital expenditure and business expansion requirements for at least
the next 12 months. However, Healtheon may need to raise additional funds within
the next 12 months to support expansion, develop new or enhanced applications
and services, respond to competitive pressures, acquire complementary businesses
or technologies or take advantage of unanticipated opportunities. Healtheon's
future liquidity and capital requirements will depend upon numerous factors,
including the success of its existing and new application and service offerings
and competing technological and market developments. Healtheon may be required
to raise additional funds through public or private financing, strategic
relationships or other arrangements. There can be no assurance that additional
funding, if needed, will be available on terms acceptable to Healtheon, or at
all.

YEAR 2000 COMPLIANCE

     Many currently installed computer systems and software products are unable
to distinguish between twentieth century dates and twenty-first century dates.
As a result, many companies' software and computer systems may need to be
upgraded or replaced to comply with these "Year 2000" requirements. Healtheon's
business is dependent on the operation of numerous systems that could
potentially be

                                       164
<PAGE>   175

impacted by Year 2000 related problems. Those systems include, among others:
hardware and software systems used by Healtheon to deliver services to its
customers, including Healtheon's proprietary software systems as well as
hardware and software supplied by third parties; communications networks, such
as the Internet and private intranets, which Healtheon depends on to provide
electronic transactions to its customers; the internal systems of its customers
and suppliers; the hardware and software systems Healtheon uses internally in
the management of its business; and non-information technology systems and
services Healtheon uses in its business, such as telephone systems and building
systems.

     Healtheon has reviewed the proprietary software systems Healtheon uses to
deliver services to its customers. Although Healtheon believes that its
internally developed applications and systems are designed to be Year 2000
compliant, Healtheon utilizes third-party equipment and software that may not be
Year 2000 compliant. In January 1999, Healtheon acquired certain electronic
laboratory connectivity devices from SmithKline Labs. SmithKline has warranted
these services to be Year 2000 compliant. Also, two systems acquired by ActaMed,
specifically SCAN and ProviderLink, which together accounted for approximately
42% of Healtheon's total revenue in 1998, will require modifications to become
Year 2000 compliant. Healtheon has released an updated version of SCAN which is
Year 2000 compliant and Healtheon is in the process of deploying the updated
version of SCAN to its customers. ProviderLink has two versions. The DOS version
was made Year 2000 compliant and is currently being deployed to Healtheon's
DOS-based customers. The Internet version is being modified to be Year 2000
compliant and Healtheon expects to begin deployment over the Internet in the
second half of 1999. Healtheon estimates the cost of these Year 2000 upgrades to
be less than $1.0 million. In addition, Healtheon's SCAN product is installed on
approximately 4,650 Healtheon-owned workstations located in provider offices.
Many of these workstations are not Year 2000 compliant and Healtheon must
upgrade or replace them. Healtheon expects the costs of such upgrades or
replacements to be less than $1.0 million. However, Healtheon could experience
delays and cost overruns in the development of these upgrades, the upgrades
could contain defects and Healtheon could experience difficulties in getting its
installed base of physicians to implement these upgrades in a timely manner. If
Healtheon experiences these or other difficulties in developing and deploying
its Year 2000 upgrades, its revenues from SCAN, ProviderLink and electronic
laboratory delivery could be significantly reduced, which could have a material
adverse effect on Healtheon's business, financial condition and results of
operations. Failure of third-party or of Healtheon's equipment or software to
operate properly with regard to the Year 2000 and thereafter could require
Healtheon to incur unanticipated expenses to remedy any problems, which could
have a material adverse effect on Healtheon's business, financial condition and
results of operations. In certain of Healtheon's agreements, Healtheon warrants
that its applications and services are Year 2000 compliant. Failure of
Healtheon's applications and services to be Year 2000 compliant could result in
the termination of these agreements or in liability for damages, either of which
could have a material adverse effect on Healtheon's business, financial
condition and results of operations. Healtheon does not believe that the
expenditures to upgrade its internal systems and applications will have a
material adverse effect on its business, financial condition and results of
operations.

     Furthermore, the success of Healtheon's efforts may depend on the success
of other healthcare participants in dealing with their Year 2000 issues. Many of
these organizations are not Year 2000 compliant, and the impact of widespread
customer failure on Healtheon's systems is difficult to determine. Customer
difficulties due to Year 2000 issues could interfere with healthcare
transactions or information, which might expose Healtheon to significant
potential liability. If client failures result in the failure of Healtheon's
systems, Healtheon's business, financial condition and results of operations
would be materially adversely affected. Furthermore, the purchasing patterns of
these customers or potential customers may be affected by Year 2000 issues as
companies expend significant resources to become Year 2000 compliant. The costs
of becoming Year 2000 compliant for current or potential customers may result in
reduced funds being available to purchase and implement Healtheon's applications
and services.

     Healtheon, with the assistance of an independent consulting firm
specializing in Year 2000 issues, has completed a formal assessment of its Year
2000 exposure and is taking steps to address the identified points of exposure.
Healtheon expects to complete its Year 2000 remediation efforts in the second
half of

                                       165
<PAGE>   176

1999. Healtheon is in the process of developing a contingency plan for handling
Year 2000 problems that are not detected and corrected prior to their
occurrence. However, Healtheon is unable to make contingency plans if any
significant number of the computers constituting the Internet fail to properly
process dates for the year 2000 and there is a system-wide slowdown or
breakdown. Any failure by Healtheon to address any unforeseen Year 2000 issue
could adversely affect Healtheon's business, financial condition and results of
operations. Any interruption or significant degradation of Internet operations,
whether due to Year 2000 problems or otherwise, could harm Healtheon's business.

RECENT ACCOUNTING PRONOUNCEMENTS

     In March 1998, the American Institute of Certified Public Accountants, or
AICPA, issued Statement of Position, or SOP, 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." SOP 98-1 requires
that entities capitalize certain costs related to internal use software once
certain criteria have been met. Healtheon is required to implement SOP 98-1 for
the year ending December 31, 1999. Adoption of SOP 98-1 is expected to have no
material impact on Healtheon's financial condition or results of operations.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, or SFAS, No. 133, "Accounting for Derivative
Instruments and Hedging Activities." Healtheon is required to adopt SFAS No. 133
for the year ending December 31, 2000. SFAS No. 133 establishes methods of
accounting for derivative financial instruments and hedging activities related
to those instruments as well as other hedging activities. Because Healtheon
currently holds no derivative financial instruments and does not currently
engage in hedging activities, adoption of SFAS No. 133 is expected to have no
material impact on its financial condition or results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate sensitivity

     The primary objective of Healtheon's investment activities is to preserve
principal while at the same time maximizing the income it receives from its
investments without significantly increasing risk. Some of the securities that
Healtheon has invested in may be subject to market risk. This means that a
change in prevailing interest rates may cause the principal amount of the
investment to fluctuate. For example, if Healtheon holds a security that was
issued with a fixed interest rate at the then-prevailing rate and the prevailing
interest rate later rises, the principal amount of Healtheon's investment will
probably decline. To minimize this risk, Healtheon maintains its portfolio of
cash equivalents and short-term investments in a variety of securities,
including commercial paper, other non-government debt securities and money
market funds. In general, money market funds are not subject to market risk
because the interest paid on such funds fluctuates with the prevailing interest
rate. In addition, Healtheon invests in relatively short-term securities. As of
December 31, 1998, all of Healtheon's investments mature in less than one year.
See note 1 of notes to Healtheon's consolidated financial statements.

     The following table presents the amounts of Healtheon's cash equivalents
and short-term investments that are subject to market risk by range of expected
maturity and weighted-average interest rates as of March 31, 1999. This table
does not include money market funds because those funds are not subject to
market risk.

Exchange rate sensitivity

     Currently the majority of Healtheon's sales and expenses are denominated in
U.S. dollars and as a result Healtheon has experienced no significant foreign
exchange gains and losses to date. While Healtheon is conducting some
transactions in foreign currencies during 1999, it does not anticipate that
foreign exchange gains or losses will be significant. Healtheon has not engaged
in foreign currency hedging activities to date.

     James H. Clark has served as Chairman of the Board of Healtheon since he
co-founded it in December 1995. Dr. Clark co-founded Netscape Communications
Corporation in April 1994 and served as the Chairman of the Board of Directors
of Netscape from its inception until it was acquired by America Online, Inc. in

BOARD OF DIRECTORS' COMMITTEES

     The Board currently has three committees: an Audit Committee, a Stock
Option Committee and a Compensation Committee.

     The Audit Committee is currently comprised of Mr. Jermoluk, Mr. Sadler, Dr.
Tyson and Dr. Yamada. The Audit Committee reviews and recommends to the Board
the internal accounting and financial controls for Healtheon and the accounting
principles and auditing practices and procedures to be used for the financial
statements of Healtheon. The Audit Committee makes recommendations to the Board
concerning the engagement of independent public accountants and the scope of the
audit to be undertaken by such accountants.

     The Stock Option Committee is currently comprised of Mr. Long and is
charged with overseeing the stock option plans as they relate to employees other
than officers and directors of Healtheon.

     The Compensation Committee is currently comprised of Dr. Clark, Mr. Doerr,
Mr. Kramlich, and Dr. McGuire. The Compensation Committee sets the compensation
of the Chief Executive Officer, reviews the design, administration and
effectiveness of compensation programs for other key executives, and approves
stock option grants to officers and directors. The Committee exercises all
authority under Healtheon's employee equity incentive plans and advises and
consults with the officers of Healtheon regarding managerial personnel policies.

DIRECTOR COMPENSATION

     Directors do not receive any cash fees for their service on the Board or
any Board committee, but they are entitled to reimbursement for all reasonable
out-of-pocket expenses incurred in connection with their attendance at Board and
Board committee meetings. All Board members are eligible to receive stock
options under the 1996 Plan, and outside directors receive stock options
pursuant to automatic grants of stock options under the 1996 Plan.

     In July 1998, Healtheon granted to each of Drs. McGuire and Yamada an
option to purchase 30,000 shares of its common stock under the 1996 Plan with an
exercise price equal to $7.00 per share. In October 1998, Drs. McGuire and
Yamada each agreed to exchange his option for a new option with an exercise
price of $3.55 per share, reflecting the fair market value of Healtheon's common
stock on that date as determined by the Board of Directors after taking into
account Healtheon's financial results and prospects. In connection with this
repricing, the vesting of the options for Drs. McGuire and Yamada was restarted.
Therefore, 25% of their shares will vest in October 1999, and the remainder will
vest ratably over the subsequent three years provided that they remain directors
of Healtheon. In January 1999, Healtheon granted to each of Dr. Clark, Mr.
Doerr, Mr. Kramlich, Dr. McGuire, Mr. Sadler and Dr. Yamada an option to
purchase 20,000 shares of its common stock under the 1996 Plan with an exercise
price equal to $3.55 per share. In February 1999, Healtheon granted to each of
Mr. Jermoluk and Dr. Tyson an option to purchase 30,000 shares of its common
stock under the 1996 Plan with an exercise price equal to $5.85 per share. The
Board also determined that under the 1996 Plan each outside director will
automatically receive an option to purchase 20,000 shares of common stock
annually on January 1.

<PAGE>   183

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Dr. McGuire, a member of the Compensation Committee, is the Chairman and
Chief Executive Officer of UnitedHealth Group, which, with its affiliates,
beneficially owns approximately 12.7% of Healtheon's common stock, and has
entered into the UnitedHealth Group Agreement and certain other agreements with
Healtheon. See "Certain Relationships and Related Transactions." No interlocking
relationship exists between the Board or Compensation Committee and the board of
directors or compensation committee of any other company, nor has any
interlocking relationship existed in the past.

LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS

     Healtheon's Certificate of Incorporation and Bylaws limit or eliminate the
personal liability of its directors for monetary damages for breach of the
directors' fiduciary duty of care. The duty of care generally requires that,
when acting on behalf of the corporation, directors exercise an informed
business judgment based on all material information reasonably available to
them. Consequently, a director or officer will not be personally liable to
Healtheon or its stockholders for monetary damages for breach of fiduciary duty
as a director, except for

     - any breach of the director's duty of loyalty to Healtheon or its
       stockholders;

     - acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases, redemptions
       or other distributions; and

     - any transaction from which the director derived an improper personal
       benefit.

     These provisions are permitted under Delaware law.

     Healtheon's Certificate of Incorporation also provides that Healtheon will
indemnify, to the fullest extent permitted by law, any person made or threatened
to be made a party to any action or proceeding by reason of the fact that he or
she is or was a director or officer of Healtheon or serves or served at any
other enterprise as a director, officer or employee at Healtheon's request.

     Healtheon's Bylaws provide that Healtheon will, to the maximum extent and
in the manner permitted by Delaware law, indemnify each of the following persons
against expenses, including attorneys' fees, judgments, fines, settlements, and
other amounts incurred in connection with any proceeding arising by reason of
the fact that he or she is or was an agent of Healtheon:

     - a current or past director or officer of Healtheon or any subsidiary of
       Healtheon;

     - a current or past director or officer of another enterprise who served at
       the request of Healtheon; or

     - a current or past director or officer of a corporation that was a
       predecessor corporation of Healtheon or any of its subsidiaries or of
       another enterprise at the request of a predecessor corporation or
       subsidiary.

     Healtheon has entered into Indemnification Agreements with each of its
directors and executive officers to give them additional contractual assurances
regarding the scope of the indemnification described above and to provide
additional procedural protections. These agreements, among other things,
indemnify Healtheon's directors and executive officers for certain expenses,
including attorneys' fees, judgments, fines, penalties and settlement amounts
incurred by them in any action or proceeding arising out of their services to
Healtheon, its subsidiaries or any other enterprise to which they provide
services at Healtheon's request. In addition, Healtheon has obtained directors'
and officers' insurance providing indemnification for Healtheon's directors,
officers and certain employees for certain liabilities. Healtheon believes that
these indemnification provisions and agreements are necessary to attract and
retain qualified directors and officers.

                                       173
<PAGE>   184

     The limited liability and indemnification provisions in Healtheon's
Certificate of Incorporation and Bylaws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary duty and may
reduce the likelihood of derivative litigation against directors and officers,
even though a derivative action, if successful, might otherwise benefit
Healtheon and it stockholders. Furthermore, a stockholder's investment in
Healtheon may be adversely affected to the extent Healtheon pays the costs of
settlement and damage awards against directors and officers of Healtheon under
these indemnification provisions.

     At present, there is no pending or threatened litigation or proceeding
involving any director, officer or employee of Healtheon where indemnification
is expected to be required or permitted, and Healtheon is not aware of any
threatened litigation or proceeding that might result in a claim for
indemnification.

equal to the fair market value of Healtheon's common stock, as determined in
good faith by the Board of Directors. The Board of Directors determined the fair
market value based on Healtheon's financial results and prospects, the share
price derived for arms-length transactions, and evaluations conducted by
valuation experts. Potential realizable values are net of exercise price before
taxes, and are based on the assumption that the common stock of Healtheon
appreciates at the annual rate shown, compounded annually, from the date of
grant until the expiration of the ten-year term. These numbers are calculated
based on Securities and Exchange Commission requirements and do not reflect
Healtheon's projection or estimate of future stock price growth.

Hoover was granted under the 1996 Stock Plan and vests as is described above.
Mr. Hoover also holds fully vested options to purchase 593,268 shares granted
under the ActaMed 1992, 1993 Class B Common and 1994 Stock Option Plans. These
options were assumed by Healtheon upon the consummation of the acquisition of
ActaMed. The option granted to Mr. Long vested immediately as to 25% of the
shares and

                                       175

vests ratably each month during the second through fourth years of his
employment as to the remainder of the shares.

COMPENSATION ARRANGEMENTS WITH EXECUTIVE OFFICERS

     In July 1997, Healtheon and Mr. Long entered into an employment agreement
under which Mr. Long became the President and Chief Executive Officer of
Healtheon. Healtheon granted Mr. Long an option to purchase 2,500,000 shares of
common stock, 25% of which vested immediately, and the remainder of which vests
ratably each month during the second through the fourth years of his employment.
In addition, Mr. Long purchased 250,000 shares for $500,000, $499,750 of which
was represented by a promissory note to Healtheon, and was issued a warrant to
purchase an additional 750,000 shares at an exercise price of $2.00 per share.
The shares issuable upon exercise of this warrant are subject to a right of
repurchase commencing on Mr. Long's employment start date and lapsing as to
31,250 shares each month. The employment agreement provides that should Mr. Long
leave Healtheon because he is no longer offered a position with similar
responsibility due to a change of control of Healtheon, Mr. Long's option vests
immediately as to 625,000 shares and Healtheon's repurchase right lapses.
Additionally, if Healtheon terminates Mr. Long's employment without cause, he
will receive six months' salary in installments, his option will vest
immediately as to 625,000 shares and Healtheon's repurchase right will lapse.

EMPLOYEE BENEFIT PLANS

     1996 Stock Plan. In February 1996 the Board adopted, and Healtheon's
stockholders approved, the 1996 Plan. Healtheon initially reserved for issuance
9,000,000 shares of common stock under the 1996 Plan. In March 1998, the Board
and the stockholders each approved an amendment to the 1996 Plan to increase the
number of shares of common stock reserved under the plan to 10,000,000 shares.
In July 1998, the Board approved, and in October 1998 the stockholders approved,
an amendment to increase the number of shares of common stock issuable under the
1996 Plan to 15,000,000 shares plus annual increases equal to the lesser of (1)
5% of the outstanding shares or (2) a lesser amount determined by the Board. In
January 1999, an additional 3,107,321 shares were reserved for issuance under
the 1996 Plan under the annual increase provision. In February 1999, the Board
and the stockholders approved an amendment to limit the automatic annual
increase provision to a maximum of 9,000,000 shares. In February 1999, the Board
and the stockholders also approved an amendment to increase the number of shares
reserved for issuance under the 1996 Plan by an additional 1,000,000 shares.
Unless terminated sooner, the 1996 Plan will terminate automatically in February
2006. The 1996 Plan provides for the discretionary grant of incentive stock
options, within the meaning of Section 422 of the Internal Revenue Code of 1986,
the "Code," to employees and for the grant of nonstatutory stock options and
stock purchase rights, "SPRs," to employees, directors and consultants. The 1996
Plan also provides for annual grants of options to purchase 5,000 shares of
common stock to each of the outside directors.

     The 1996 Plan may be administered by the Board or a committee of the Board,
as applicable, the "Administrator". The Administrator has the power to determine
the terms of the options or SPRs granted, including the exercise price of the
options or SPRs, the number of shares subject to each option or SPR, the
exercisability thereof, and the form of consideration payable upon such
exercise. In addition, the Administrator has the authority to amend, suspend or
terminate the 1996 Plan, provided that no share of common stock previously
issued and sold or any option previously granted under the 1996 Plan is
affected.

     The exercise price of all incentive stock options granted under the 1996
Plan must be at least equal to the fair market value of the common stock on the
date of grant. The exercise price of nonstatutory stock options and SPRs granted
under the 1996 Plan is determined by the Administrator, but with respect to
nonstatutory stock options intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the exercise
price must be at least equal to the fair market value of the common stock on the
date of grant. With respect to any participant who owns stock possessing more
than 10% of the voting power of all classes of Healtheon's outstanding capital
stock, the exercise price of any incentive stock option granted must be at least
equal 110% of the fair market value on the grant date and its term must not
exceed five years. The term of all other options granted under the 1996 Plan may
not

                                       176
<PAGE>   187

exceed ten years. Options generally vest as to 25% at the end of the first year
and monthly thereafter over a period of three years so that the entire option is
vested after four years, based upon the optionee's continued employment or
consulting relationship with Healtheon.

     In the case of SPRs, unless the Administrator determines otherwise, the
restricted stock purchase agreement will grant Healtheon a repurchase option
exercisable upon the voluntary or involuntary termination of the purchaser's
employment or consulting relationship with Healtheon for any reason, including
death or disability. The purchase price for shares repurchased pursuant to a
restricted stock purchase agreement must be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to Healtheon. The repurchase option will lapse at a rate determined by the
Administrator.

     Options and SPRs granted under the 1996 Plan are generally not transferable
by the optionee, and each option and SPR is exercisable during the lifetime of
the optionee only by the optionee. Options granted under the 1996 Plan must
generally be exercised within 30 days after the end of optionee's status as an
employee, director or consultant of Healtheon, or within one year after such
optionee's termination by disability or death, respectively, but in no event
later than the expiration of the option's term.

     The 1996 Plan provides that, in the event of a merger of Healtheon with or
into another corporation, each outstanding option and SPR must be assumed or an
equivalent option substituted by the successor corporation. If the outstanding
options and SPRs are not assumed or substituted by the successor corporation,
the outstanding options and SPRs will terminate.

     ActaMed Stock Option Plans. In connection with its acquisition of ActaMed
in a merger, Healtheon assumed the outstanding options of ActaMed under the
following ActaMed stock option plans, which are collectively referred to as the
"ActaMed Plans": ActaMed Corp. 1992 Stock Option Plan, ActaMed Corp. 1993 Class
B common stock Option Plan, ActaMed Corp. 1994 Stock Option Plan, ActaMed Corp.
1995 Stock Option Plan, ActaMed Corp. 1996 Stock Option Plan, ActaMed Corp. 1997
Stock Option Plan and ActaMed Corp. 1996 Director Stock Option Plan. The
following options held by directors and executive officers of Healtheon were
assumed by Healtheon: options to purchase 1,424,216 shares of ActaMed common
stock held by Michael Hoover, options to purchase 250,000 shares of ActaMed
common stock held by Nancy Ham, options to purchase 80,000 shares of ActaMed
common stock held by J. Philip Hardin, and options to purchase 220,000 shares of
ActaMed common stock held by John R. Hughes, Jr. As a result of the merger, each
option to purchase shares of ActaMed common stock now represents an option to
purchase a number of shares of Healtheon common stock equal to .6272 times the
number of shares of ActaMed common stock originally subject to the option at the
per share exercise price equal to the original per share exercise price divided
by .6272. Healtheon will make no further grants under the ActaMed Plans.
However, each assumed ActaMed option continues to have and remains subject to
substantially the terms and conditions of the applicable ActaMed Plan under
which such option was originally granted as in effect immediately prior to the
merger.

     Generally, options granted under the ActaMed Plans will automatically
terminate ten years following their issuance. Options granted under the ActaMed
Plans generally are not transferable by the optionee, and must generally be
exercised within 30 days after the end of the optionee's status as an employee
or consultant of Healtheon or within 90 days after such optionee's termination
by disability or death, respectively, but in no event later than the expiration
of the option's term. Generally, in the event of any merger, sale of stock,
consolidation, liquidation, recapitalization, reclassification, stock split up,
combination of shares, share exchange, stock dividend, or transaction having a
similar effect, where Healtheon does not remain in existence, the Administrator
may (1) declare that all ActaMed options shall vest in full and be exercisable
for a period of thirty (30) days following written notice from the
Administrator, after which all ActaMed options shall terminate, (2) provide that
all ActaMed options shall be assumed by the successor corporation, or (3)
provide for a combination of the above.

     1998 Employee Stock Purchase Plan. Healtheon's 1998 Employee Stock Purchase
Plan, or the "1998 Purchase Plan," was adopted by the Board in September 1998,
and approved by the stockholders in October 1998. A total of 1,000,000 shares of
common stock has been reserved for issuance under the 1998

                                       177
<PAGE>   188

Purchase Plan, plus annual increases equal to the lesser of (1) 500,000 shares,
(2) .5% of the outstanding shares on such date or (3) a lesser amount determined
by the Board.

     The 1998 Purchase Plan contains consecutive, overlapping, twenty-four month
offering periods. Each offering period includes four six-month purchase periods.
The offering periods generally start on the first trading day on or after May 1
and November 1 of each year, except for the first such offering period which
commences on the first trading day on or after the effective date of this
offering and ends on the last trading day on or before October 31, 2000.

     Employees are eligible to participate if they are employed by Healtheon or
any participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, an employee may not be granted an option
to purchase stock under the 1998 Purchase Plan if the employee (1) immediately
after grant would own stock possessing 5% or more of the total combined voting
power or value of all classes of the capital stock of Healtheon, or (2) holds
rights to purchase stock under any employee stock purchase plans of Healtheon
that together accrue at a rate which exceeds $25,000 worth of stock for each
calendar year. The 1998 Purchase Plan permits each participant to purchase
common stock through payroll deductions of up to 15% of the participant's
"compensation." Compensation is defined as the participant's base straight time
gross earnings and commissions but excludes payments for overtime, shift
premium, incentive compensation, incentive payments, bonuses and other
compensation. The maximum number of shares a participant may purchase during a
single purchase period is 5,000 shares.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the 1998 Purchase Plan is 85% of the lower of the fair market
value of the common stock (1) at the beginning of the offering period or (2) at
the end of the purchase period. In the event the fair market value at the end of
a purchase period is less than the fair market value at the beginning of the
offering period, the participants will be withdrawn from the current offering
period following exercise and automatically re-enrolled in a new offering
period. The new offering period will use the lower fair market value as of the
first date of the new offering period to determine the purchase price for future
purchase periods. Participants may end their participation at any time during an
offering period, and they will be paid their payroll deductions to date.
Participation ends automatically upon termination of employment with Healtheon.

     Rights granted under the 1998 Purchase Plan are not transferable by a
participant other than by will or the laws of descent and distribution. The 1998
Purchase Plan provides that, in the event of a merger of Healtheon with or into
another corporation or a sale of substantially all of Healtheon's assets, each
outstanding option may be assumed or substituted for by the successor
corporation. If the successor corporation refuses to assume or substitute for
the outstanding options, the offering period then in progress will be shortened
and a new exercise date will be set. The 1998 Purchase Plan will terminate in
2008. The Board has the authority to amend or terminate the 1998 Purchase Plan,
except that no amendment or termination may adversely affect any outstanding
options under the 1998 Purchase Plan. The Board may alter the purchase price for
any offering period or shorten an offering period at any time without consent of
the stockholders or of any participants.

     401(k) Plan. Healtheon participates in a tax-qualified employee savings and
retirement plan, or the "401(k) Plan," which covers all of Healtheon's full-time
employees who have completed three months of service. Under the 401(k) Plan,
eligible employees may defer up to 20% of their pre-tax earnings, subject to the
Internal Revenue Service's annual contribution limit. The 401(k) Plan permits
additional discretionary matching contributions by Healtheon on behalf of all
participants in the 401(k) Plan in such a percentage amount as may be determined
annually by the Board. To date, Healtheon has made no matching contributions.
The 401(k) Plan is intended to qualify under Section 401 of the Code, as
amended, so that contributions by employees or by Healtheon to the 401(k) Plan,
and income earned on plan contributions, are not taxable to employees until
withdrawn from the 401(k) Plan, and so that contributions by Healtheon, if any,
will be deductible by Healtheon when made. The trustee under the 401(k) Plan, at
the direction of each participant, invests the assets of the 401(k) Plan in any
of a number of investment options.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Since January 1, 1998, there has not been nor is there currently proposed
any transaction or series of similar transactions to which Healtheon or any of
its subsidiaries was or is to be a party in which the amount involved exceeds
$60,000 and in which any director, executive officer, holder of more than 5% of
the common stock of Healtheon or any member of the immediate family of any of
the foregoing persons had or will have a direct or indirect material interest
other than (1) compensation agreements and other arrangements, which are
described where required in "Executive Compensation" and (2) the transactions
described below.

ActaMed Corporation Acquisition

     On May 19, 1998, Healtheon acquired ActaMed in a merger. In connection with
the merger, Healtheon issued 23,271,355 shares of its common stock in exchange
for all of the issued and outstanding capital stock of ActaMed, and assumed all
options to purchase ActaMed common stock. The merger was treated as a tax-free
reorganization and as a "pooling-of-interests" transaction for accounting and
financial reporting purposes. All of the then outstanding shares of preferred
stock of Healtheon were converted into shares of common stock of Healtheon upon
the consummation of the merger.

Transactions with Directors, Executive Officers and 5% Stockholders

     On May 19, 1998, in connection with the ActaMed merger, each outstanding
share of preferred stock of Healtheon converted into one share of common stock
and each outstanding warrant to purchase shares of Healtheon's preferred stock
converted into a warrant to purchase shares of Healtheon's common stock.

     1998 Series A Preferred Stock. On November 3, 1998 and November 6, 1998,
Healtheon sold an aggregate of 7,683,341 shares of its Series A preferred stock
for $6.00 per share. Among the purchasers were the following 5% stockholders and
entities affiliated with directors of Healtheon, who purchased the number of
shares indicated:

     - Atherton Properties Partnership, LP, an entity controlled by Dr. Clark
       and affiliated with Kathy Clark and Michael Clark -- 166,667 shares;

     - Kathy Clark -- 166,667 shares;

     - Michael James Clark Trust -- 166,667 shares;

     - HLM Partners VII, LP, of which UnitedHealth Group is a limited
       partner -- 166,667 shares;

     - KPCB Java Fund -- 416,667 shares;

     - Kleiner Perkins Caufield & Byers -- 375,000 shares;

     - KPCB Life Sciences Zaibatsu Fund II -- 41,667 shares;

     - Monaco Partners, LP, an entity wholly controlled by Dr.
       Clark -- 2,850,000 shares; and

     - New Enterprise Associates VI, LP -- 416,667 shares.

     Upon the closing of Healtheon's initial public offering in February 1999,
each share of Series A preferred stock converted into one share of common stock.

     Sadler Relationships. Companies affiliated with Mr. Sadler had agreements
with ActaMed whereby ActaMed provided office space, phone facilities and
computer network support. ActaMed was paid approximately $204,000 in 1998 under
those agreements.

     Officer Loan. In March 1999, Healtheon loaned Steve Curd, an officer of
Healtheon, $2.5 million for the purchase of a residence upon his relocation to
the San Francisco Bay Area. The loan is secured, bears no interest, and must be
repaid by Mr. Curd upon the earlier of the end of five years, the sale of the
residence, or the discontinuation of his employment with Healtheon. Mr. Curd
also must apply to the loan any proceeds received by him from the sale of
Healtheon common stock resulting from the exercise of his stock options.
Healtheon has agreed to repurchase the residence from Mr. Curd upon his request

Certain Business Relationships

SmithKline Labs

     1997-1998 Services Agreements. Prior to the acquisition of ActaMed by
Healtheon, ActaMed entered into a series of agreements, the SmithKline
Agreements, with SmithKline Labs, which agreements were assumed by Healtheon in
the ActaMed merger. Under one of the SmithKline Agreements, the Services
Agreement, Healtheon will perform laboratory test order and results services to
providers utilizing SmithKline Labs' laboratory services through Healtheon's
SCAN application. SmithKline Labs was obligated to pay Healtheon a minimum of
approximately $10.0 million in 1998 for laboratory test orders and results
transactions and is obligated to pay $9.1 million in 1999 and $9.1 million in
2000. SmithKline Labs may be required to pay Healtheon certain additional fees
for transactions processed by Healtheon in the event the number of providers
accessing SmithKline Labs' laboratory services through SCAN increases.
SmithKline Labs paid Healtheon $10.4 million in service and transaction fees
during 1998 under the Services Agreement. The Services Agreement is effective
through December 2002, and provides for automatic successive two-year renewals,
subject to each party's right to elect not to renew the agreement no later than
180 days, in the case of SmithKline Labs, or 360 days, in the case of Healtheon,
prior to the end of a term. In the event that Healtheon gives notice of
non-renewal, SmithKline Labs will be entitled to continued to receive long-term
order entry and results reporting services from Healtheon on a per transaction
pricing basis or, in the alternative, may require Healtheon to develop a service
for SmithKline that duplicates the services Healtheon had been providing under
the Services Agreement.

     Also under the Services Agreement, SmithKline Labs is entitled, no more
than once in any three consecutive month periods, to request that Healtheon
engage in certain exclusive development work for SmithKline Labs. SmithKline
Labs has agreed to use reasonable efforts to use Healtheon as its "preferred
provider" of electronic eligibility verification and claims processing services.
The Services Agreement provides that the parties will negotiate new rates as of
January 1, 2001 and each two years after that date. The Services Agreement
states that the renegotiated rates must be competitive with the marketplace and
must be no higher than the lowest fees charged by Healtheon to similarly
situated customers.

     Asset Purchase Agreement. Also under one of the SmithKline Agreements, the
Asset Purchase Agreement, ActaMed agreed to purchase certain assets, or the
SmithKline Assets, located in four geographic regions, received a technology
license relating to the SmithKline Assets and agreed to provide certain
continuing development and network services to SmithKline Labs. In December
1997, SmithKline Labs transferred a portion of the SmithKline Assets from the
first region to ActaMed in exchange for $2.0 million in cash and 3,695,652
shares of ActaMed preferred stock. The shares of ActaMed preferred stock issued
to SmithKline were converted into 2,317,913 shares of Healtheon's common stock
in connection with the ActaMed merger. In March 1998, SmithKline Labs
transferred the SmithKline Assets from the second region to ActaMed in exchange
for 1,217,391 shares of ActaMed preferred stock. Those shares were converted
into 763,548 shares of Healtheon's common stock in connection with the ActaMed
merger. In June 1998, SmithKline Labs transferred SmithKline Assets from the
remaining two regions to Healtheon in exchange for 1,336,209 shares of Healtheon
common stock.

     Noncompete Letter. In May 1998, Healtheon and SmithKline Labs entered into
a letter agreement under which Healtheon is obligated not to compete with
SmithKline Labs in the business of disease management, and has agreed to
exclusively promote SmithKline Labs' disease management products and services so
long as SmithKline continues to promote Healtheon as its preferred vendor.
Healtheon also

                                       180
<PAGE>   191

agreed that, in the event it performs development work related to a disease
management program for one of its customers or itself, it will pay 50% of the
profits from that development work to SmithKline Labs.

     1999 Agreements. In December 1998, Healtheon and SmithKline Labs entered
into a services agreement under which Healtheon will provide certain electronic
laboratory results delivery services to approximately 20,000 provider sites, in
addition to the sites currently served through the SCAN service. The services
agreement has a five year term with anticipated revenues of $17.0 to $18.0
million in the first year. Healtheon does not expect this arrangement to
significantly contribute to earnings in the near term. In addition, Healtheon
agreed to purchase, and in January 1999, Healtheon purchased certain assets used
by SmithKline Labs to provide laboratory results delivery services in exchange
for $2.0 million in cash and 1,833,333 shares of Healtheon's common stock.
Profitability will depend on Healtheon's ability to use these assets to provide
results delivery services for non-SmithKline labs and to transition these
provider sites to Healtheon's Internet-based services. On February 9, 1999,
SmithKline Beecham announced that it has agreed to sell SmithKline Labs to Quest
Diagnostics, Incorporated.

UnitedHealth Group

     EDI Services Acquisition. In March 1996, ActaMed acquired EDI Services, a
wholly-owned subsidiary of UnitedHealth Group, which had been formed by
UnitedHealth Group to deliver the ProviderLink service to UnitedHealth Group's
provider network. In exchange for EDI, ActaMed issued UnitedHealth Group
10,344,828 shares of ActaMed preferred stock valued at $21.0 million which were
converted into 6,488,276 shares of Healtheon's common stock in connection with
the merger.

     Services Agreement. In April 1996, ActaMed also entered into a Services and
License Agreement with UnitedHealth Group that granted UnitedHealth Group a
license to certain ActaMed technology and granted ActaMed the responsibilities
of managing the ProviderLink service and of providing other information
technology services to UnitedHealth Group. UnitedHealth Group pays Healtheon
fees based on the number of ProviderLink sites in use and transactions
processed. In 1998, ActaMed, prior to the merger, and Healtheon were paid an
aggregate of $10.4 million related to services, transaction and license fees.
Healtheon is also obligated to provide certain support and maintenance services
to UnitedHealth Group. The Services and License Agreement is effective through
March 2001 subject to earlier termination in the event Healtheon fails to meet
certain network performance standards or otherwise breaches its material
obligations under the UnitedHealth Group Agreement. The Service and License
Agreement provides that two years after the date of the agreement the parties
will agree on new prices that will be competitive with the marketplace.
Healtheon and UnitedHealth Group are negotiating these new prices, and Healtheon
anticipates that the new prices will reduce the rates paid by UnitedHealth
Group. See "Management's Discussion and Analysis -- Overview" and Note 2 of
Notes to Consolidated Financial Statements included in our Annual Report on Form
10-K. UnitedHealth Group is a principal stockholder of Healtheon and Dr. William
McGuire, Chief Executive Officer and Chairman of UnitedHealth Group, is a
director of Healtheon.

     HLM Note. In February 1998, ActaMed issued a one-year promissory note in
the aggregate principal amount of $2.0 million to HLM Partners VII, L.P., or
HLM, which bore interest at a rate of 10% per annum. UnitedHealth Group was a
limited partner of HLM. HLM was also a stockholder of ActaMed.

and information functions. WebMD provides healthcare consumers with free access
to a broad range of healthcare-related information and online healthcare
communities.

answering service, customized physician Web sites and content from recognized
market leaders. WebMD intends to enhance its current services and content and

Web browsers. Therefore, subscribers who use WebMD's services do not require
training on multiple proprietary devices.

     Although WebMD views its strategic relationships as a key factor in its
overall business strategy and in the development and commercialization of its
services, WebMD cannot guarantee that its strategic partners will view their
relationships with WebMD as significant to their own business or that they will
not reassess their relationship with WebMD in the future.

Sales and Marketing

     WebMD markets its services through an internal sales force and its
strategic distribution relationships which typically couple WebMD's use of the
strategic partner's services or content with the strategic partner's marketing
of WebMD's services to its customer or client base. WebMD's distribution
partners, which target different healthcare sectors, combined with WebMD's
internal sales force, provide WebMD with sales, and marketing professionals who
are experienced in the healthcare industry. WebMD and WebMD's strategic
partners' direct marketing efforts, which may include promotional offers, direct
mail and telemarketing initiatives, emphasize the ease of use and adoption,
attractive pricing and integrated solution offered by WebMD. WebMD has entered
into, and intends to continue to enter into, strategic alliances with parties
who have established customer or client bases that have an anticipated need for
the services provided by WebMD. In connection with some of these strategic
alliances, such as the alliances with Microsoft, DuPont, McKessonHBOC, E*TRADE,
and MedQuist, WebMD has agreed to bear some of the cost associated with these
promotional offers or to compensate such partners for each subscriber that WebMD
obtains through their marketing efforts or to make guaranteed payments to some
of its distribution partners and service and content providers. WebMD intends to
enter into similar promotional arrangements in the future. WebMD has also
issued, and may issue in the future, warrants in connection with entering into
strategic alliances, such as its alliances with Microsoft, DuPont, McKessonHBOC
and Premier. For a more complete description, see the section entitled "WebMD
Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Promotional arrangements" and "-- Guaranteed payments."

     WebMD is currently engaged in a significant branding and advertising
campaign to increase awareness of the WebMD brand. WebMD is employing a
combination of print and online advertising and other marketing and promotional
efforts aimed at defining a desirable online destination for healthcare
professionals and consumers, attracting new subscribers and consumers,
increasing traffic on the WebMD Web site and developing additional revenue
opportunities. WebMD promotes its Web-based services through traditional print
media, including trade journals, newspapers and magazines targeted at healthcare
professionals, and participates in tradeshows, conferences and speaking
engagements as part of its ongoing public relations program. In addition, WebMD
has entered into several strategic alliances to promote the WebMD brand offline,
including the alliance with CNN which provides for the promotion of WebMD on
television and radio. WebMD plans to continue to allocate significant resources
to marketing its services.

Customer Service and Support

     WebMD believes that effective customer service is essential to attracting
and retaining subscribers and consumers. WebMD provides ongoing telephone
support through its customer service and sales support centers which are
accessible by a toll-free call and are available from 8:00 a.m. to 8:00 p.m.,
Eastern time Monday through Friday. WebMD's live operators screen all requests
for telephone support and direct the call to the appropriate customer service
personnel. Technical support personnel are responsible for consulting with
WebMD's strategic partners regarding technical support issues and for resolving
technical problems encountered by users, strategic partners or other parties.
Through CompuServe, WebMD will provide 24-hour customer service for WebMD
subscribers who use CompuServe as their Internet service provider.

Competition

     Web-based services. The market for Web-based services and products is
relatively new, intensely competitive and rapidly changing. Since the Internet's
commercialization in the early 1990's, the number of Web sites on the Internet
competing for users' attention has proliferated with no substantial barriers to
entry. WebMD expects competition in the markets in which it competes to increase
significantly as new companies enter these markets and current competitors
expand their product lines and services. Competition may also increase as a
result of industry consolidation. Many of these potential competitors are likely
to enjoy substantial competitive advantages, including:

     - greater resources that they can devote to the development, promotion and
       sale of their services;

     - longer operating histories;

     - greater financial, technical and marketing resources;

     - greater name recognition; and

     - larger subscriber and consumer bases.

     WebMD does not know whether its current or potential competitors will
develop products and services comparable or superior to WebMD's products and
services or adapt more quickly than WebMD to new technologies, evolving industry
trends or changing Internet user preferences. Increased competition could result
in price reductions, reduced margins or loss of market share, any of which would
significantly harm WebMD.

     WebMD competes, directly and indirectly, for subscribers, consumers,
content and service providers, advertisers, sponsors and acquisition candidates
with the following categories of companies:

     - online services or Web sites targeted to the healthcare industry and
       healthcare consumers generally, including medscape.com, pol.net,
       mediacareonline.com, mediconsult.com, betterhealth.com, drkoop.com,
       onhealth.com, iVillage.com, healthcentral.com and thriveonline.com;

     - publishers and distributors of traditional offline media, including those
       targeted to healthcare professionals, many of which have established or
       may establish Web sites;

     - general purpose consumer online services and portals which provide access
       to healthcare-related content and services;

     - public sector and non-profit Web sites that provide healthcare
       information without advertising or commercial sponsorships;

     - vendors of healthcare information, products and services distributed
       through other means, including direct sales, mail and fax messaging; and

     - Web search and retrieval services and other high-traffic Web sites.

In addition, with regard to its electronic data interchange service offering,
WebMD also competes with providers of single function electronic data
interchange terminals, such as those provided by VeriFone Inc. WebMD generally
does not have the contractual right to prevent its subscribers from terminating
their service or changing to a competing service.

     WebMD believes that the principal competitive factors in attracting and
retaining healthcare professional subscribers are brand recognition and the
depth, breadth and timeliness of its services and content. Other important
factors in attracting and retaining healthcare professionals as subscribers
include the ease of use, quality and cost of WebMD's services. WebMD believes
that the principal competitive factors that attract advertisers include price,
the number of healthcare professionals who subscribe to WebMD, the traffic on
its Web site, the demographics of its subscriber and consumer bases and the
creative implementation of advertisement placements.

                                       193
<PAGE>   204

     Communications and information services. WebMD also competes in the
communications and information services markets. These markets are also
intensely competitive, rapidly evolving and subject to rapid technological
change. Other providers currently offer each of the individual services and
certain combinations of the services that WebMD offers. WebMD's voice mail
services compete with voice mail services provided by regional Bell operating
companies as well as by independent voice mail vendors. WebMD's communications
services and features, such as conference calling, compete with services
provided by companies with significantly greater resources than WebMD as well as
smaller interexchange long distance providers. Telecommunications companies also
compete for consumers based on price, and major competitors often conduct
extensive advertising campaigns to capture market share. A decrease in rates
charged by WebMD's telecommunications competitors could have a material adverse
effect on its business. WebMD expects that the communications and information
services markets will continue to attract new entrants and new technologies,
possibly including alternative technologies that are more sophisticated and cost
effective than WebMD's technology.

     To be competitive in these markets, WebMD must license leading
technologies, enhance its existing services and content, develop new
technologies that address the increasingly sophisticated and varied needs of
healthcare professionals and healthcare consumers and respond to technological
advances and emerging industry standards and practices on a timely and
cost-effective basis. WebMD may not be successful in using new technologies
effectively or adapting its Web site and proprietary technology to user
requirements or emerging industry standards. Any pricing pressures, reduced
margins or loss of market share resulting from WebMD's failure to compete
effectively would significantly harm WebMD.

Government Regulation and Legal Uncertainties

     Internet laws. There are currently few laws or regulations that
specifically regulate communications or commerce on the Internet. However, laws
and regulations may be adopted in the future that address issues such as online
content, user privacy, pricing and quality of products and services. For
example, local exchange carriers have petitioned the Federal Communications
Commission to regulate Internet service providers and online service providers
in a manner similar to long distance telephone carriers. The local exchange
carriers want the Federal Communications Commission to impose access fees on
those providers because the growing popularity and use of the Internet has
burdened the existing telecommunications infrastructure. Internet user privacy
has become an issue both in the U.S. and abroad. Although the U.S. or other
countries may adopt legislation to protect privacy, no current U.S. law
specifically covers the collection of personal information online. Any
legislation of this nature could affect the way WebMD conducts its business,
especially its collection or use of personal information, and could harm its
business. In addition, it may take years to determine the extent to which
existing laws governing issues such as property ownership, libel, negligence and
personal privacy are applicable to the Internet.

     The tax treatment of the Internet and e-commerce is currently unsettled. A
number of proposals have been made at the federal, state and local level and by
certain foreign governments that could impose taxes on the sale of goods and
services and certain other Internet activities. A recently-passed law places a
temporary moratorium on certain types of taxation on Internet commerce. WebMD
cannot predict the effect of current attempts to tax or regulate commerce over
the Internet. Any legislation that substantially impairs the growth of
e-commerce could harm WebMD's business.

     Healthcare laws. Currently, WebMD's operations are not regulated by any
healthcare agency. However, the Health Insurance Portability and Accountability
Act of 1996 mandates the use of standard transactions and identifiers, security
and other provisions regarding healthcare issues on the Internet by the end of
the year 2000. It will be necessary for WebMD's platform and for the
applications that WebMD provides to be in compliance with the proposed
regulations. Congress is also likely to consider legislation establishing
uniform, comprehensive federal rules about an individual's right to access his
own or someone else's medical information. This legislation would likely define
what is to be considered "protected health information" and outline steps to
ensure the confidentiality of this information. The proposed Health Information
Modernization and Security Act would provide for establishing standards and
requirements for the electronic transmission of health information.

                                       194
<PAGE>   205

     Food and Drug Administration regulation of medical devices. The Food and
Drug Administration regulates some computer applications and software that it
considers medical devices. The Food and Drug Administration might decide to
regulate WebMD's current services, although WebMD does not believe that they
will do so. Expansion of WebMD's services may subject it to future regulation.
WebMD has no experience in complying with Food and Drug Administration
regulations and doing so could be time consuming, burdensome and expensive and
could delay or prevent its introduction of new services.

     Regulation of the practice of medicine. The practice of medicine requires
licensing under applicable state law. WebMD attempted to structure its Web site
and strategic relationships to avoid violating state licensing requirements. A
state regulatory authority may, however, allege that some portion of WebMD's
business violates these statutes and seek to have us discontinue those portions
or cause us to suffer financial damage. Further, WebMD's insurance may not cover
any liability based on a determination that we engaged in the practice of
medicine without a license.

     State insurance regulation. WebMD markets online insurance offered by third
parties, and receives referral fees from those providers in connection with this
activity. Online marketing of insurance is a relatively new practice. It is not
clear whether or to what extent state insurance licensing laws apply to these
activities. It could be costly or impossible for WebMD to comply with these
licensing laws, if compliance is required.

Intellectual Property

     WebMD's proprietary rights. WebMD relies on a combination of copyright,
trademark and trade secret laws and contractual provisions to establish and
protect its proprietary rights. WebMD has applied for federal registration of
the service marks "WebMD," "Web-MD," "WebMD OnCall," "Health has a Homepage" and
"WebRN." By letter dated July 6, 1998, the Patent & Trademark Office refused
registration of the "Web-MD" mark when used on or in connection with WebMD's
services. WebMD responded to the Patent & Trademark Office's refusal of
registration and was orally informed that the service mark "Web-MD" has been
cleared for publication for opposition. WebMD has applied for registration of
the service marks "WebMD," "Health has a Homepage" and "WebRN" in approximately
75 foreign countries. WebMD cannot guarantee that it will be able to secure
registration for these marks in the United States or in foreign countries. WebMD
has also registered the domain name "webmd.com."

     The steps WebMD has taken to protect its proprietary rights may not be
adequate, and WebMD may not be able to secure trademark or service mark
registrations for marks in the U.S. or in foreign countries. Third parties may
infringe upon or misappropriate WebMD's copyrights, trademarks, service marks
and similar proprietary rights. In addition, effective copyright and trademark
protection may be unavailable or limited in many foreign countries, and the
global nature of the Internet makes it impossible to control the ultimate
destination of its services. It is possible that competitors or others will
adopt product or service names similar to WebMD's names, which could impede
WebMD's efforts to build brand identity and possibly lead to customer confusion.
Moreover, because domain names derive value from the individual's ability to
remember such names, WebMD's domain name will lose its value if, for example,
users begin to rely on mechanisms other than domain names to access online
resources. WebMD's inability to protect its marks adequately would hurt WebMD's
ability to establish its brand. In the future, litigation may be necessary to
enforce and protect WebMD's trade secrets, copyrights and other intellectual
property rights. Litigation would divert management resources and be expensive
and may not effectively protect WebMD's intellectual property.

     Third-party proprietary rights. WebMD also relies on a variety of
intellectual property rights that it licenses from third parties, including its
Internet server software and healthcare content used on the WebMD Web site.
These third party licenses may not be available to WebMD on commercially
reasonable terms. WebMD's loss of or inability to maintain or obtain upgrades to
any of these licenses could significantly harm WebMD. In addition, because WebMD
licenses a majority of its content from third parties, WebMD's exposure to
copyright infringement actions may increase because it must rely upon such
parties for information as to the origin and ownership of such licensed content.

                                       195

Facilities

     WebMD's corporate headquarters and call center occupy approximately 20,000
square feet of office space in Atlanta, Georgia under a lease expiring February
1, 2000, with an option to renew the lease term for one year. In addition, WebMD
leases approximately 5,300 square feet of space in Atlanta, Georgia for its
emergency call center. WebMD also has offices in Portland, Oregon and San
Francisco, California. WebMD believes that its current office space is
sufficient to meet its present needs and does not anticipate any difficulty
securing additional space, as needed, on terms acceptable to it.

Employees

     As of March 31, 1999, WebMD employed 165 persons on a full-time basis. None
of WebMD's employees are members of a labor union or are covered by a collective
bargaining agreement. WebMD believes that its relationship with employees is
good.

Legal Proceedings

     In connection with the sale of its cardiac monitoring assets to Matria,
WebMD and its subsidiary Endeavor (formerly known as Quality Diagnostic
Services, Inc.), retained liabilities, including liabilities relating to actual
and potential litigation. These liabilities include potential sanctions
associated with Endeavor's receipt of service of a civil subpoena from the
Department of Health and Human Services, Office of the Inspector General on July
28, 1998. Endeavor responded to the subpoena in a timely manner on August 31,
1998. In a letter from the OIG dated November 25, 1998, the OIG requested that
Matria, as successor in interest to Endeavor's cardiac monitoring business,
should put in place measures to ensure proper use of facsimile machines and
telephone lines and periodically certify that these measures are being
effectively implemented to provide assurances that facsimile machines and
telephone lines used in the offices of referral sources are dedicated to cardiac
monitoring. The OIG has orally stated that it intends to enter into a settlement
agreement related to the subpoena that will describe the proper measures.

     These liabilities also include a lawsuit filed in the Circuit Court for the
Judicial Circuit in and for Duval County, Florida by Brenda G. Durant under the
caption Brenda G. Durant, as personal representative of the Estate of James R.
Durant, deceased v. Jackson Heart Center, P.A., Jay Dunerman and Quality
Diagnostic Services, Inc. (No. 98-06052/CA). The complaint alleges a cause of
action for negligence for failure to notify plaintiff's physician of an abnormal
and potentially life threatening heart monitor recording which was received and
maintained by QDS. WebMD is currently in the process of filing an answer to the
complaint. Defending the lawsuit against QDS may involve significant expense.
Due to the inherent uncertainties of litigation, there can be no certainty as to
the ultimate outcome.

     In addition, these retained liabilities include a potential claim by Life
Watch, an Illinois corporation and subsidiary of Ralin Medical, Inc., which in
February 1998 asserted orally that WebMD's use of cardiac monitoring devices
constituted an infringement of a patent held by Life Watch. Life Watch then
offered to grant license rights to WebMD under the patent. WebMD informed Life
Watch that Card Guard Scientific Survival, Ltd., an independent third party,
owns all rights to the devices and that Endeavor was merely a distributor of
such devices. There has been no further action in this regard. In the event that
this matter results in litigation, an adverse decision could result in
substantial damages and attorneys' fees that could harm WebMD.

     On March 4, 1999, a lawsuit was filed in the Superior Court of the State of
California for the County of Los Angeles by Derek Rundell and Gary Coursey under
the caption Derek Rundell and Gary Coursey v. WebMD, Inc. (No. BC206440),
against WebMD. The complaint alleges breach of oral contract, breach of implied
covenant of good faith and fair dealing, breach of implied-in-fact contract,
fraud, unfair competition and constructive trust. The plaintiffs were former
employees of certifiedemail.com, Inc., which WebMD acquired on December 31,
1998. The plaintiffs allege, among other things, that WebMD breached oral
contracts of continued employment and committed fraud against the plaintiffs by
inducing them to accept employment with WebMD. On March 24, 1999, WebMD filed
its answer to the complaint in which it denied the material allegations of
liability. WebMD strongly disputes the material legal and

                                       196
<PAGE>   207

factual allegations contained in the complaint and believes that the complaint
is without merit. WebMD intends to vigorously defend against the action. On
March 22, 1999, WebMD filed a complaint against Gary B. Coursey and
certifiedemail.com in the Superior Court of Fulton County, State of Georgia
under the caption WebMD, Inc. v. Gary B. "Court" Coursey, Jr. and
certifiedemail.com, Inc. (No. 1999CV06474). The complaint alleges, among other
things, that defendants breached representations and warranties contained in the
asset purchase agreement between WebMD and certifiedemail.com. The complaint
also alleges that Mr. Coursey breached his employment agreement with WebMD.
Defending the lawsuit against WebMD and pursuing the lawsuit against Mr. Coursey
and certifiedemail.com may involve significant expense. Due to the inherent
uncertainties of litigation, there can be no certainty as to the ultimate
outcome.

     From time to time, WebMD may be involved in litigation relating to claims
arising out of its operations. WebMD is not currently a party to any other legal
proceedings, the adverse outcome of which, individually or in the aggregate,
would have a material adverse effect on its business, financial condition or
operating results.

                 WEBMD MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion should be read in conjunction with WebMD's
consolidated financial statements and the related notes thereto and other
financial information appearing elsewhere in this proxy statement/prospectus.

OVERVIEW

     WebMD provides services to healthcare professionals and healthcare
consumers under its WebMD brand name. WebMD's subscription-based professional
Web site includes access to electronic data interchange services, enhanced
communications services, healthcare-related information and other Web-based
services that are useful to healthcare professionals. WebMD designed its
professional Web site to simplify healthcare practices by integrating multiple
administrative, communications and research functions into a single, easy to use
Web-based solution. WebMD's free consumer Web site includes access to premium,
branded healthcare-related information, personalized, targeted information about
specific health conditions and content-specific online communities that allow
consumers to participate in real-time discussions and support networks via the
Web. WebMD designed its consumer Web site to assist consumers in making informed
healthcare decisions.

     WebMD was formerly engaged in the cardiac monitoring business, and WebMD
has only recently begun implementing its new Web-based business model. WebMD's
activities to date have primarily consisted of licensing and creating content,
negotiating relationships with strategic partners, engaging in marketing and
branding promotions, recruiting personnel and raising capital. WebMD
commercially launched its Internet-based services in October 1998.

Recent acquisitions

     Sapient Health Network. Sapient Health Network designed and managed
Web-based communities targeted at healthcare consumers and sold market research
and data products, advertising sponsorships and other online services. Business
Week named Sapient Health Network's Web site one of the best new Web sites of
1998. On January 25, 1999, WebMD acquired Sapient Health Network for 1,619,190
shares of WebMD's Series B preferred stock. In addition, WebMD converted Sapient
Health Network's existing options and warrants into options and warrants to
acquire 180,953 shares of WebMD's Series B preferred stock. At closing, WebMD
also paid $2.9 million of liabilities of Sapient Health Network. This
acquisition was accounted for using the purchase method of accounting.

     Direct Medical Knowledge. Direct Medical Knowledge was a publisher of
healthcare information via the Internet through its electronic library of
healthcare information which was customized for consumers through its
proprietary personalization software. On January 22, 1999, WebMD acquired Direct
Medical Knowledge in exchange for 494,018 shares of WebMD's Series B preferred
stock. In addition, WebMD converted existing Direct Medical Knowledge options
and warrants into options and warrants to acquire 181,323 shares of WebMD's
Series B preferred stock. At closing, WebMD also forgave $300,000 of debt
payable by Direct Medical Knowledge to WebMD. This acquisition was accounted for
using the purchase method of accounting.

     Charges in connection with acquisitions. As a result of the Sapient Health
Network and Direct Medical Knowledge acquisitions, WebMD recorded an aggregate
of $51.9 million in goodwill and other intangible assets in the first quarter of
1999, which WebMD will amortize on a straight-line basis over a three-year
period.

Stock dividend

     On April 9, 1999, WebMD's board of directors declared a stock dividend of
0.03846 shares of Series F preferred stock, which is convertible into common
stock on a ten-for-one basis, for each share of WebMD capital stock outstanding.
In addition, WebMD's board approved adjustments to each WebMD

                                       199
<PAGE>   210

option and warrant outstanding on April 9, 1999 to reflect the stock dividend,
regardless of whether these options and warrants were vested and exercisable.
Unless otherwise indicated, the stock dividend has been reflected as if it had
occurred for all periods presented.

Service offerings

     WebMD markets subscriptions to its Internet-based services to healthcare
professionals. WebMD currently offers its subscribers two monthly service
packages: WebMD and WebMD OnCall. The following are some of the service
offerings included in WebMD and WebMD OnCall:

     - electronic data interchange services for eligibility verifications and
       patient referrals;

     - the Virtual Receptionist integrated messaging platform, which manages
       incoming calls, voice mails, e-mails and fax messages;

     - a customized physician Web site;

     - practice management tools;

     - physician medical references;

     - continuing medical education courses; and

     - access to financial services and products, as well as news, stock, sports
       and travel information.

     A subscription to WebMD OnCall also includes WebMD's physician-only
answering service. WebMD's current base subscription fees for WebMD and WebMD
OnCall are $29.95 and $99.95 per month, respectively. The WebMD and WebMD OnCall
packages generally require a 12-month service period and are generally
terminable upon 90 days prior written notice. WebMD also offers Internet access
and paging services for additional monthly fees.

Promotional arrangements

     WebMD currently funds promotions of its services through its distribution
relationships with Microsoft, DuPont, McKessonHBOC, MedQuist and E*TRADE. WebMD
generally requires subscribers under these promotional arrangements to commit to
12-to-36 month subscriptions. WebMD has entered into these promotional
arrangements in order to establish its subscriber base and build brand
recognition. WebMD's promotional arrangements currently require, and future
arrangements may require, it to pay amounts that WebMD will only recoup if
subscribers maintain a subscription and pay all required subscription fees for
an extended period of time.

     WebMD cannot guarantee that it will generate sufficient revenue from
subscribers it obtains through current or future promotional arrangements to
offset the cost of its promotions. WebMD's promotional arrangements include the
sponsorship of WebMD subscriptions by some of WebMD's strategic partners. These
sponsorships require the strategic partners to pay WebMD for subscriptions that
the partners are unable to sell to their existing customers. Although WebMD
expects to receive revenue from these arrangements, WebMD cannot predict the
number of actual subscribers, if any, that these relationships will actually
generate. WebMD also cannot guarantee that subscribers it obtains through
promotional arrangements will actually use its services. Therefore, the amount
of revenue WebMD receives may not be indicative of the level of usage of WebMD's
services and WebMD expects the level of usage of its Web site to be a primary
factor in determining the amount of advertising revenue that it can derive.

Guaranteed payments

     WebMD estimates that it will make the following aggregate guaranteed
payments under its current strategic agreements:

<TABLE>

                          PERIOD                               AMOUNT
                          ------                            -------------
<S>                                                         <C>
April - December 1999.....................................  $66.4 million
2000......................................................   72.5 million
2001......................................................   78.3 million
2002......................................................   40.4 million
2003......................................................   34.4 million
</TABLE>

WebMD may enter into additional promotional arrangements with current and future
strategic partners that may require it to pay consideration in amounts that
significantly exceed the amounts WebMD is required to pay under its current
arrangements. These guaranteed payments and promotional and other arrangements
may require WebMD to incur significant expenses. WebMD cannot guarantee that it
will generate sufficient revenues to offset these expenses.

Revenues and results of operations

     WebMD anticipates that the majority of its revenues will initially consist
of subscription revenues paid by its subscribers and strategic partners. WebMD
recognizes revenue when services are provided. Advance billings and collections
relating to future access services will be recorded as deferred revenue and
recognized when revenue is earned. If WebMD is successful in building its
subscriber base and brand recognition and increasing traffic on its Web site,
WebMD expects advertising, sponsorship and transaction revenues to increase as a
percentage of total revenues.

     WebMD has incurred net operating losses and negative cash flows from
operating activities since its inception. As of March 31, 1999, WebMD had an
accumulated deficit of $43.0 million. WebMD has not achieved profitability, and
WebMD expects to incur increasing net operating losses and negative cash flows
for the foreseeable future. WebMD will incur significant direct expenses
associated with its branding and advertising campaign, promotional arrangements,
and with the development of its services. WebMD may not be able to achieve
sufficient revenues in relation to its expenses to ever be profitable. If WebMD
achieves profitability, it may not be able to sustain or increase profitability
on a quarterly or annual basis. In addition, WebMD expects its quarterly
revenues, expenses and operating results to fluctuate significantly in the
future as a result of a variety of factors, some of which are outside WebMD's
control.

     As a result of its limited operating history, its recent acquisitions and
the emerging nature of the markets in which it intends to compete, WebMD is
unable to forecast its revenues with any degree of certainty. WebMD's current
and projected expense levels are based largely on its estimates of future
revenues and are mostly fixed. WebMD expects its expenses to increase
significantly in the future as it continues to incur significant sales and
marketing, product development and administrative expenses. The success of its
business depends on WebMD's ability to increase its revenues to offset expenses.
WebMD cannot guarantee that it will be able to generate sufficient revenues to
offset operating expenses or the costs of its promotional arrangements or that
WebMD will be able to achieve or maintain profitability. If WebMD revenues fall
short of its projections, WebMD's business, financial condition and operating
results would be materially and adversely affected.

Historical operating results

     Effective July 1, 1998, WebMD sold substantially all of its cardiac
monitoring assets to Matria for an aggregate purchase price of $17.0 million in
cash and up to $6.0 million in additional contingent consideration payable
subject to the achievement during calendar year 1999 of certain revenue goals by
Matria in the operation of the purchased assets. Substantially all of WebMD's
historical revenues were derived from its cardiac monitoring operations. WebMD
does not consider the historical results of its

                                       201
<PAGE>   212

cardiac monitoring operations to be meaningful or indicative of its future
results of operations. WebMD's financial statements reflect the cardiac
monitoring operations as discontinued operations for all periods and dates prior
to such sale of assets. As of March 31, 1999, WebMD has not recorded any amounts
relating to the contingent consideration described above.

RESULTS OF OPERATIONS

     In June 1997, WebMD began redirecting its focus to the development of
integrated Web-based administrative, communications and information services to
healthcare professionals and healthcare information to consumers. WebMD
commercially launched its Internet-based services in October 1998. WebMD
believes that year-to-year comparisons of its results of operations for the
years ended December 31, 1998 and 1997 and the period-to-period comparisons of
the results of operations for the three months ended March 31, 1999 and 1998 are
not meaningful and should not be relied upon as an indication of WebMD's future
performance.

Revenues

     During the year ended December 31, 1998 and the three months ended March
31, 1999, WebMD generated $408,000 and $2.5 million, respectively, in revenues.
WebMD did not generate any revenues from its continuing operations for the year
ended December 31, 1997 and for the three months ended March 31, 1997. Revenues
increased primarily due to the launch of WebMD's Internet-based services.

Operating expenses

     Product development and content. Product development and content costs
consist of Web development fees, content license fees, fees to service providers
and salaries and related expenses. Product development and content costs are
expensed as incurred. Product development and content costs were $7.5 million
and $566,000 for the years ended December 31, 1998 and 1997, respectively, and
$5.6 million and $695,000 for the three months ended March 31, 1999 and 1998,
respectively. In 1998, product development and content costs increased primarily
due to fees of $4.5 million for the development of its Web site and content
license fees of $1.4 million and other research and development. Product
development and content costs increased for the three months ended March 31,
1999 primarily due to content license fees of $2.3 million, fees of $1.2 million
for development of the WebMD Web site and $1.1 million in salaries and related
expenses of development personnel.

     Sales and marketing. Sales and marketing costs consist of salaries and
related expenses and advertising, marketing and promotional expenses. Sales and
marketing costs are expensed as incurred. Sales and marketing costs were $3.7
million and $213,000 for the years ended December 31, 1998 and 1997,
respectively, and $8.8 million and $63,000 for the three months ended March 31,
1999 and 1998, respectively. Sales and marketing costs increased primarily due
to payments to WebMD's consumer portal distribution partners, including
promotional arrangements, its branding and advertising campaign and increased
marketing efforts in connection with the distribution of its services.

     General and administrative. General and administrative expenses consist
primarily of salaries, non-cash compensation charges and related expenses for
executive and administrative functions and other expenses. General and
administrative expenses were $10.1 million and $1.8 million for the years ended
December 31, 1998 and 1997, respectively, and $2.7 million and $509,000 for the
three months ended March 31, 1999 and 1998, respectively. In 1998, general and
administrative expenses increased primarily due to $3.2 million in non-cash
compensation charges related to the issuance of options to employees with an
exercise price less than the fair market value of WebMD's capital stock on the
date of issuance, $2.0 million in salaries and related expenses for additional
executive and administrative personnel, $1.7 million for contract labor and $1.7
million in professional fees. General and administrative costs increased for the
three months ended March 31, 1999 primarily due to salaries and related expenses
for additional administrative and executive personnel.

                                       202
<PAGE>   213

     Write down of customer terminals. For the year ended December 31, 1998,
WebMD recorded a charge of $1.8 million to write down computer terminals to
their net realizable value. WebMD previously offered computer terminals with
some of its promotional packages or as a option for an additional fee. In 1998,
WebMD changed its service offerings to no longer offer computer terminals.

     Depreciation and amortization. Depreciation and amortization expense
consists of the depreciation of property and equipment and the amortization of
intangible assets. Depreciation and amortization was $303,000 and $9,000 for the
years ended December 31, 1998 and 1997, respectively and $3.5 million and
$10,000 for the three months ended March 31, 1999 and 1998, respectively.
Depreciation and amortization increased due to the amortization of intangible
assets and purchases of property and equipment for the expansion of WebMD's
service offerings. In the three months ended March 31, 1999, WebMD recorded $2.9
million in amortization expense in connection with the acquisitions of Sapient
Health Network, Direct Medical Knowledge and certifiedemail.com. WebMD will
amortize the remaining $50.9 million in intangible assets on a straight-line
basis over the remainder of its three-year life.

     Interest expense, net. Interest income (expense), net consists primarily of
interest paid on loans from related parties, loans that have been repaid and
interest earned on cash balances. Interest income (expense), net was $(139,000)
and $(725,000) for the years ended December 31, 1998 and 1997, respectively, and
$214,000 and $(146,000) for the three months ended March 31, 1999 and 1998,
respectively. Interest income (expense), net decreased for the year ended
December 31, 1998 due to the repayment of an aggregate of $6.0 million in loans
from Sirrom Investments, Inc. and a $509,605 loan from a related party and
interest earned on WebMD's investment of cash received from the sale of its
cardiac monitoring assets and the sale of its capital stock. Interest income
(expense), net increased for the three months ended March 31, 1999 to reflect
interest income earned on cash balances, net of interest expense.

     Discontinued operations. Effective as of July 1, 1998, WebMD sold
substantially all of its cardiac monitoring assets to Matria. WebMD incurred a
loss from discontinued operations of $1.2 million and $1.7 million for the years
ended December 31, 1997 and 1996, respectively. For the year ended December 31,
1998, WebMD recognized a gain of $7.7 million on the sale of its cardiac
monitoring operations. On July 1, 1997, WebMD sold UltraScan, a diagnostic
imaging services provider, and recognized a gain on the UltraScan sale of
$165,000 for the year ended December 31, 1997.

     Income taxes. At March 31, 1999, WebMD had total net operating loss
carryforwards for federal and state income tax purposes of $31.7 million that
expire in years 2010 through 2014. Utilization of WebMD's net operating loss
carryforwards may be subject to an annual limitation due to the "change of
ownership" provisions of the tax code and similar state provisions. The annual
limitation may result in the expiration of net operating losses and credits
before utilization. For financial reporting purposes, a valuation allowance has
been recognized to reduce the net deferred tax assets to zero due to
uncertainties with respect to WebMD's ability to generate taxable income in the
future sufficient to realize the benefit of deferred income tax assets.

LIQUIDITY AND CAPITAL RESOURCES

     Since its inception, WebMD has financed its operations primarily through
private debt financings, the sale of its cardiac monitoring operations and the
sale of its capital stock.

     Loans from Sirrom Investments, Inc. On August 29, 1997, WebMD borrowed $4.0
million from Sirrom for working capital and general corporate purposes. In
connection with the loan, WebMD issued Sirrom a warrant to purchase 771,901
shares of Series D common stock. In July 1998, WebMD borrowed an additional $2.0
million from Sirrom as bridge financing prior to the closing of the sale of
WebMD's cardiac monitoring operations to Matria. WebMD used $6.0 million of the
proceeds from the sale of its cardiac operations to repay the loans from Sirrom.

     Sale of WebMD's cardiac monitoring operations. Effective as of July 1,
1998, WebMD sold substantially all of its cardiac monitoring assets to Matria
for an aggregate purchase price of $17.0 million

                                       203
<PAGE>   214

in cash and up to $6.0 million additional contingent consideration payable
subject to Matria's achievement during calendar year 1999 of certain revenue
goals in the operation of the purchased assets. In July 1998, WebMD used $2.7
million of the proceeds for settlement costs of a dissenting stockholder law
suit related to Endeavor. For a more complete description of the lawsuit, see
"WebMD's Management -- Compensation Committee Interlocks and Insider
Participation -- Dissenting Stockholder Lawsuit." WebMD also used $6.0 million
of the proceeds to pay the loans outstanding to Sirrom. The remainder of the
proceeds were used for WebMD's branding and advertising campaign, development of
its services and other general corporate purposes.

     Sales of WebMD's capital stock. During the years ended December 31, 1998
and 1997, WebMD received $15.9 million and $5.8 million, respectively from the
sale of its capital stock. During the three months ended March 31, 1999 and
1998, WebMD received $34.0 million and $1.1 million, respectively, from the sale
of its capital stock.

     Recent acquisitions. On December 31, 1998, WebMD acquired substantially all
of the assets and assumed certain liabilities of certifiedemail.com, Inc. in
exchange for 50,000 shares of WebMD's Series D common stock. On January 22,
1999, WebMD also acquired Direct Medical Knowledge for 494,018 shares of WebMD's
Series B preferred stock. In addition, WebMD converted existing Direct Medical
Knowledge options and warrants into options and warrants to acquire 181,323
shares of WebMD's Series B preferred stock. At closing, WebMD also paid $300,000
in certain liabilities of Direct Medical Knowledge. On January 25, 1999, WebMD
acquired Sapient Health Network for 1,619,190 shares of WebMD's Series B
preferred stock. In addition, WebMD converted existing Sapient Health Network
options and warrants into options and warrants to acquire 180,953 shares of
WebMD's Series B preferred stock. At closing, WebMD also paid $2.9 million of
liabilities of Sapient Health Network. Series D common stock and Series B
preferred stock exchanged in these acquisitions were valued at $20.00 per share
which was determined to be the fair market value of these securities by WebMD's
board in the absence of a liquid market based on recent sales of similar
securities to third parties.

Sources and Uses of Liquidity

     As of March 31, 1999, WebMD's primary source of liquidity consisted of $9.7
million in cash and cash equivalents, and WebMD had working capital of $23.5
million.

     Net cash used in continuing operations was $17.6 million and $3.6 million
for the years ended December 31, 1998 and 1997, respectively, and $24.6 million
and $1.3 million for the three months ended March 31, 1999 and 1998,
respectively. The principal uses of cash in continuing operations during 1998
were to fund WebMD's net loss of $16.4 million from operations, which was
partially offset by a $3.4 million in changes in accounts payable and accrued
expenses and $3.4 million in non-cash compensation expense in continuing
operations during 1998. The principal uses of cash in continuing operations
during the three months ended March 31, 1999 were to fund WebMD's net loss of
$17.8 million from operations, which was partially offset by $3.5 million in
depreciation and amortization, $2.0 million in non-cash amortization equity
issued for services, a $9.4 million increase in other current assets and a
decrease of $2.1 million in accounts payable and accrued expenses.

     Net cash provided by (used in) investing activities was $9.5 million and
$(1.6) million for the years ended December 31, 1998 and 1997, respectively, and
$(3.7) million and $(1.1) million for the three months ended March 31, 1999 and
1998, respectively. Net cash used in investing activities during 1997 primarily
related to purchases of property and equipment related to discontinued
operations. Net cash provided by investing activities during 1998 primarily
related to $16.6 million in net proceeds from the sale of discontinued
operations, partially offset by $4.5 million in purchases of property and
equipment related to continuing and discontinued operations and payment of $2.7
million in settlement of a dissenting stockholder lawsuit. Net cash used in
investing activities during the three months ended March 31, 1999 primarily
related to purchases of property and equipment related to continuing operations.

     Net cash provided by financing activities of continuing operations was
$11.9 million and $9.7 million for the year ended December 31, 1998 and 1997,
respectively, and $31.7 million and $1.3 million for the

                                       204
<PAGE>   215

three months ended March 31, 1999 and March 31, 1998, respectively. Financing
activities during 1998 consisted primarily of the proceeds from the issuance of
equity securities and proceeds from the $2.0 million loan from Sirrom and the
repayment of the $6.0 million loan from Sirrom. Financing activities during the
three months ended March 31, 1999 consisted primarily of proceeds from the
issuance of equity securities, partially offset by a $2.2 million repayment of a
capital lease.

     If the Healtheon-WebMD reorganization is not consummated, WebMD believes
that the net proceeds from the recent sales of securities will be sufficient to
fund its working capital and capital expenditure requirements for at least the
next 12 months. However, WebMD expects to continue to incur significant
operating losses for at least the next 24 months due to its branding and
advertising campaign and the development of its services. If the Healtheon-WebMD
reorganization is not consummated and WebMD determines that it will require
additional funds to support operations or the expansion of its business, WebMD
may sell additional equity, issue debt or convertible securities or obtain
credit facilities through financial institutions. The sale of additional equity
or convertible securities will result in additional dilution to WebMD's
stockholders. There can be no assurance that additional financing, if required,
will be available to WebMD in amounts or on terms acceptable to WebMD.

YEAR 2000 COMPLIANCE

     Some computers, software and other equipment include programming code in
which calendar year data is abbreviated to only two digits. As a result of this
design decision, some of these systems could fail to operate or fail to produce
correct results if "00" is interpreted to mean 1900, rather than 2000. These
problems are widely expected to increase in frequency and severity as the year
2000 approaches and are commonly referred to as the "Year 2000 Problem."

     Assessment. The Year 2000 Problem could affect computers, software and
other equipment that WebMD uses. WebMD has completed a review of its internal
computer programs and systems to determine if they will be Year 2000 compliant.
WebMD believes that its computer systems will be Year 2000 compliant in a timely
manner. However, while WebMD does not expect the cost of these efforts to be
material to its financial position or any year's operating results, WebMD cannot
provide you with any assurance to this effect.

     Internal Infrastructure. WebMD believes that it has identified
substantially all of the major computers, software applications and related
equipment that WebMD uses in connection with its internal operations that must
be modified, upgraded or replaced to minimize the possibility of a material
disruption to its business. WebMD has started modifying, upgrading and replacing
systems that it has identified as potentially being adversely affected. WebMD
expects to complete this process before the end of the third quarter of 1999.
WebMD does not expect the cost related to these efforts to be material to its
business, financial condition or operating results.

     Systems Other Than Information Technology Systems. In addition to computers
and related systems, the operation of WebMD's office and facilities equipment,
such as fax machines, photocopiers, telephone switches, security systems,
elevators and other common devices may be affected by the Year 2000 Problem.
WebMD is currently assessing the potential effect of, and costs of remediating,
the Year 2000 Problem on this equipment. WebMD does not expect that the total
cost of completing any required modifications, upgrades or replacements of these
internal systems will have a material effect on its business, financial
condition or operating results.

     Suppliers. WebMD depends on third party suppliers for most of the services
it provides. If these parties are affected by the Year 2000 Problem, WebMD's
ability to provide services to our subscribers and users may be materially
adversely affected. WebMD has been gathering information from and has initiated
communications with all of its service and content providers to identify and, to
the extent possible, resolve issues involving the Year 2000 Problem. WebMD has
received written responses from iXL, ENVOY, Premiere Technologies, MedQuist,
AHT, Physicians Data Network and J&C Nationwide addressing their Year 2000
readiness. Based on these responses, WebMD believes these service providers will
be Year 2000 ready. However, WebMD has limited or no control over the actions of
its service and content providers.

                                       205
<PAGE>   216

Therefore, while WebMD expects that it will be able to resolve any significant
Year 2000 Problems with its systems, WebMD cannot guarantee that its service and
content providers will resolve any or all Year 2000 Problems with their systems
before the occurrence of a material disruption to WebMD's business. Any failure
of these third parties to resolve Year 2000 problems with their systems in a
timely manner could have a material adverse effect on WebMD's business,
financial condition or operating results.

     Most Likely Consequences of Year 2000 Problems. WebMD expects to identify
and resolve all Year 2000 Problems that could materially adversely affect its
business, financial condition or operating results. However, WebMD believes that
it will not be possible to determine with complete certainty that all Year 2000
Problems affecting WebMD have been identified or corrected. The number of
devices that could be affected and the interactions among these devices are
simply too numerous. In addition, WebMD cannot accurately predict how many
failures related to the Year 2000 Problem will occur or the severity, duration
or financial consequences of such failures. As a result, WebMD could possibly
suffer the following consequences:

     - a significant number of operational inconveniences and inefficiencies for
       WebMD, its service and content providers and subscribers and users that
       may divert time and attention and financial and human resources from
       WebMD's ordinary business activities; and

     - a lesser number of serious system failures that may require significant
       efforts by WebMD, its service and content providers or WebMD's
       subscribers and users to prevent or alleviate material business
       disruptions.

     Contingency Plans. WebMD is currently developing contingency plans to be
implemented as part of its efforts to identify and correct Year 2000 Problems
affecting its internal systems. WebMD expects to complete its contingency plans
by the end of the third quarter of 1999. Depending on the systems affected,
these plans could include (1) accelerated replacement of affected equipment or
software; (2) short to medium-term use of backup equipment and software; (3)
increased work hours for our personnel or use of contract personnel to correct
on an accelerated schedule any Year 2000 Problems which arise or to provide
manual workarounds for information systems; and (4) other similar approaches. If
WebMD is required to implement any of these contingency plans, such plans could
have a material adverse effect on its financial condition or operating results.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131 is effective
for financial statements for periods beginning after December 15, 1997. SFAS No.
131 establishes standards for disclosures about operating segments, products and
services, geographic areas and major customers.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     WebMD's financial instruments consist of cash that is invested in
institutional money market funds. At March 31, 1999, the carrying values of
WebMD's financial instruments approximated their fair values based on current
market prices and rates. It is WebMD's policy not to purchase or hold derivative
financial instruments. WebMD does not have significant foreign currency exposure
since it does not currently transact business in foreign currencies. Therefore,
WebMD did not have significant overall currency exposure at March 31, 1999.

CHANGE IN INDEPENDENT ACCOUNTANTS

     On February 23, 1997, Direct Medical Knowledge dismissed Berg & Company as
its independent accountants. The report of Berg & Company on Direct Medical
Knowledge's financial statements for the period from inception (May 24, 1995)
through December 31, 1996 contained no adverse opinion or disclaimer of opinion.
The opinion was qualified as to the uncertainty of Direct Medical Knowledge's

                                       206
<PAGE>   217

ability to continue as a going concern. In connection with these audits and
through February 23, 1997, there had been no disagreements with Berg & Company
on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreement if not resolved
to the satisfaction of Berg & Company would have caused them to make reference
thereto in their report on the financial statements for such periods. The
decision to change accounting firms was approved by Direct Medical Knowledge's
management. Direct Medical Knowledge has requested that Berg & Company furnish
it with a letter addressed to the Commission stating whether or not it agrees
with the above statements. A copy of that letter, dated June 15, 1999, is filed
as an exhibit to the registration statement of which the proxy
statement/prospectus forms a part.

     Direct Medical Knowledge engaged PricewaterhouseCoopers LLP as its new
independent accountants as of February 23, 1997. During the period from
inception (May 24, 1995) through February 23, 1997, Direct Medical Knowledge had
not consulted with PricewaterhouseCoopers LLP on items which (1) were or should
have been subject to Statement of Auditing Standards No. 50 or (2) concerned the
subject matter of a disagreement or reportable event with Berg & Company.

which establishes the compensation of WebMD's executive officers, including

DIRECTOR COMPENSATION

     WebMD awards options to purchase common stock to non-employee directors for
their service on the board of directors. Each non-employee director received a
grant of options to acquire 27,692 shares of Series D common stock at an
exercise price of $10.83 per share on November 13, 1998, the date the Director
Option Plan of WebMD, Inc. was approved. Each non-employee director received a
grant of options to acquire 6,923 shares of Series D common stock at an exercise
price of $14.44 on January 1, 1999. See "-- Option Plans -- Director Option
Plan." WebMD reimburses its directors for out-of-pocket expenses incurred in
connection with their rendering of services as directors. WebMD has not paid and
does not intend to pay cash fees to our directors for attendance at meetings.

     Effective May 22, 1998, William P. Payne became an employee and the
Chairman of the board of Orchestrate.com, a wholly-owned subsidiary of Premiere
Technologies. As Chairman of Orchestrate.com, one of Mr. Payne's principal
duties is to assist WebMD in the development of WebMD's business for the purpose
of increasing revenue opportunities for Premiere Technologies and enhancing the

reimburses Premiere Technologies $375,000 per year for Mr. Payne's salary,
$125,000 per year for Mr. Payne's minimum bonus and $6,000 per year for Mr.
Payne's automobile allowance, each for the balance of Mr. Payne's two-year
employment with Orchestrate.com. In addition, WebMD granted Mr. Payne options to
acquire 276,920 shares of Series D common stock with an exercise price of $1.44
per share. WebMD also reimburses Mr. Payne for any expenses he incurs in
discharging his duties to WebMD.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The compensation committee of WebMD's board of directors was formed on
September 17, 1998. The current members of the compensation committee are Lucius
E. Burch, III and Jouko J. Rissanen. Neither Messrs. Burch nor Rissanen has been
an officer or employee of WebMD at any time.

     For the three months ended March 31, 1999 and for years ended December 31,
1996, 1997 and 1998, WebMD paid approximately $1,200, $2,100, $5,000 and $4,800,
respectively, in health, life and dental insurance premiums for Mr. Rissanen and
his wife.

     In August 1996, Mr. Rissanen loaned $200,000 to Endeavor pursuant to an
oral agreement. In March 1998, pursuant to a conversion of debt, indemnification
and release agreement among WebMD,

                                       210
<PAGE>   221

Endeavor, Mr. Rissanen and Finn Partners, a general partnership of which Mr.
Rissanen is the managing partner and in which he owns a 16.7% interest, the
parties agreed to convert such debt into 100,000 shares of Series D common stock
which were issued to Finn Partners.

     In January 1997, WebMD loaned Jeffrey T. Arnold $4,000 to purchase
4,000,000 shares of common stock, Mr. Rissanen $1,400 to purchase 1,400,000
shares of Series B common stock and Mr. Burch $1,000 to purchase 1,000,000
shares of Series C common stock. These unsecured loans were evidenced by
promissory notes bearing interest at the rate of 8.75% per annum. Principal and
interest on the loans have been paid in full.

     Dissenting Stockholder Lawsuit. In March 1997, a majority of the
stockholders of Endeavor approved and adopted a plan and agreement of merger
providing for the merger of Endeavor into QDS Acquisition Corporation, WebMD's
wholly owned subsidiary, with Endeavor surviving. Prior to this merger, the
stockholders of Endeavor consisted of: Messrs. Arnold, Rissanen and Burch;
Robert A. Frist; and nine physicians. Messrs. Arnold, Rissanen, Burch and Frist,
who owned a majority of Endeavor's capital stock, voted for the merger. The
minority stockholders of Endeavor asserted the right granted to them under
Georgia law to dissent with regard to such action and to demand payment for the
fair value of their shares in exchange for the surrender of such shares.
Approval of the merger was also required by WebMD as the sole stockholder of QDS
Acquisition Corporation. WebMD's board of directors was, thus, required to
approve the merger. The merger was approved unanimously by the board, which at
that time consisted of Messrs. Arnold, Rissanen, Burch and Frist and three other
individuals. In addition, at the time of the merger, WebMD's four largest
stockholders were Messrs. Arnold, Rissanen, Burch and Frist, and the sole voting
stockholder was Mr. Arnold. In July 1998, WebMD paid an aggregate of $2.7
million to settle the dissenters' rights action and entered into a consulting
agreement with one of the dissenting stockholders.

EXECUTIVE COMPENSATION

     The following table sets forth all compensation awarded to, earned by or
paid for services rendered to WebMD in all capacities during the fiscal year
ended December 31, 1998 by WebMD's Chief Executive Officer and each of WebMD's
other two highest paid executive officers whose total compensation exceeded
$100,000 (the "Named Executive Officers").

</TABLE>

     All options vest one-third on the date of grant and one-sixth, one-sixth
and one-third on the first three anniversaries of the date of grant. The
percentage of total options granted to employees during the fiscal year is based
on a total of 3,123,840 options granted to all employees during the fiscal year
ended December 31, 1998. All options were granted at an exercise price equal to
the fair market value of the common stock on the date of grant. Potential
realizable values are computed by (1) multiplying the number of shares of common
stock subject to a given option by the exercise price and (2) assuming that the
aggregate stock value derived from that calculation compounds at the annual rate
of 5% and 10% for the remainder of the four-year term of the option. In
accordance with the rules of the Securities and Exchange Commission, the
potential realizable values for such options shown in the table are based on
assumed rates of stock price appreciation of 5% and 10% compounded annually from
the date the respective options were granted to their expiration date. These
assumed rates of appreciation do not represent our estimate or projection of the
appreciation of shares of our common stock.

     The following table sets forth information concerning exercisable and
unexercisable stock options held as of December 31, 1998 by each of the Named
Executive Officers. No options were exercised by the Named Executive Officers in
1998.

     The value of unexercised in-the-money options at December 31, 1998 was
determined by subtracting the exercise price from $14.44 per share, the fair
market value of WebMD capital stock at December 31, 1998 as determined in good
faith by the WebMD board.

EMPLOYMENT AGREEMENTS

     WebMD has an employment agreement effective September 30, 1998 with Jeffrey
T. Arnold. His employment agreement has a two-year term and renews for
consecutive one-year terms, unless either party gives 360-days notice prior to
the expiration of any term. WebMD pays Mr. Arnold an annual salary of $180,000,
and WebMD may pay him an annual bonus as determined by the board (or the
compensation committee). Mr. Arnold has agreed not to compete with WebMD during
the term of his employment and for one year after his termination. If WebMD
terminates Mr. Arnold without cause, Mr. Arnold will be entitled to 12 months'
salary as severance. WebMD granted Mr. Arnold options to acquire 1,384,600
shares of Series D common stock in his employment agreement. His options vest
one-third on the date of

                                       212
<PAGE>   223

grant and one-sixth, one-sixth and one-third on the first three anniversaries of
the date of grant. All of Mr. Arnold's options will immediately vest and become
exercisable in the event of a change of control, whether by contract, ownership
of voting securities or otherwise, of the direct or indirect power to direct the
management and policies of WebMD. A change of control will be deemed to have
occurred if any person or entity that is not on the date of his employment
agreement the beneficial owner of any securities becomes the beneficial owner of
20% or more of the combined voting power of WebMD's outstanding voting
securities which would have the right to vote for the election of WebMD's
directors. In connection with the Healtheon-WebMD reorganization, Mr. Arnold
agreed to waive any change of control vesting which would occur as a result of
the reorganization. If Mr. Arnold is terminated after the reorganization for any
reason other than cause, all his options will immediately vest.

     WebMD also has employment agreements effective February 1, 1998 and July
11, 1997 with K. Robert Draughon and W. Michael Heekin, respectively. Their
employment agreements have two-year terms and renew for one additional term
unless either party gives 180-days notice prior to the end of the initial
two-year term. WebMD pays Messrs. Draughon and Heekin an annual salary of
$175,000 and $150,000, respectively, and WebMD may pay either of them an annual
bonus as determined by WebMD's board of directors or the compensation committee.
They have each agreed not to compete with WebMD during the term of their
employment and for one year thereafter. If WebMD terminates either of them
without cause, they will be entitled to 12 month's salary as severance. WebMD
granted Messrs. Draughon and Heekin options to acquire 366,919 and 415,380
shares, respectively, of Series D common stock. Their options vest one-third on
the date of employment and one-sixth, one-sixth and one-third on the first three
anniversaries of the date of their initial employment.

OPTION PLANS

     1997 Stock Incentive Plan. In September 1997, the WebMD board of directors
adopted and WebMD's stockholders approved the WebMD, Inc. 1997 Stock Incentive
Plan under which 2,769,200 shares of common stock of WebMD are available to be
granted to employees, consultants and others rendering services to WebMD. The
1997 Stock Incentive Plan is effective as of January 1, 1997 by its terms. In
September 1998 and April 1999, the WebMD board adopted certain amendments to the
1997 Stock Incentive Plan, which provided, in part, for the increase in the
number of authorized shares of common stock under the 1997 Stock Incentive Plan
to 6,923,000 and 8,307,600, respectively. In March 1999, the WebMD board adopted
amendments to the 1997 Stock Incentive Plan which provided for estate and gift
planning transfers approved by the compensation committee. The amendments to the
1997 Stock Incentive Plan were approved by the WebMD's stockholders in January
1999 and March 1999, respectively. Options may be either incentive stock options
within the meaning of Section 422 of the tax code, which permits the deferral of
taxable income related to the exercise of such options, or nonqualified options
not entitled to such deferral. Incentive stock options may only be granted to
employees. In addition, the 1997 Stock Incentive Plan allows for the award of
restricted stock. In April 1999, WebMD's board adjusted the shares of common
stock underlying the awards in connection with WebMD's stock dividend.

     The 1997 Stock Incentive Plan is administered by the WebMD board and the
compensation committee. Subject to the provisions of the 1997 Stock Incentive
Plan, the WebMD board and the compensation committee, in their discretion,
select the recipients of awards and the number of options granted thereunder and
determine other matters including (1) vesting and exercisability schedules, (2)
the exercise price of options, which cannot be less than 100% of the fair market
value of the common stock on the date of grant for all stock options and (3) the
duration of awards.

     As of June 15, 1999, the Company had granted options to purchase
shares of Series D common stock of WebMD outstanding under the 1997 Stock
Incentive Plan. In addition, WebMD assumed options to acquire an aggregate of
362,276 shares of Series B preferred stock in connection with the Sapient Health
Network and Direct Medical Knowledge acquisitions.

                                       213

     Director Option Plan. In November 1998, WebMD's board adopted the Director
Option Plan of WebMD, Inc., which was approved by WebMD's stockholders in
January 1999. The Director Option Plan provides for non-qualified stock options
to be granted to WebMD's non-employee directors. The Director Option Plan
authorizes the issuance of up to 1,000,000 shares of common stock pursuant to
options having an exercise price equal to the fair market value of the common
stock on the date the options are granted. In April 1999, WebMD's board adjusted
the shares of common stock underlying the awards in connection with WebMD's
stock dividend.

     The Director Option Plan provides for an initial grant of options to
acquire 27,692 shares of common stock to each non-employee director who served
on WebMD's board on November 13, 1998. The Director Option Plan also provides a
grant of options to acquire 27,692 shares of common stock to each non-employee
director who is elected to WebMD's board after the date of approval of the
Director Option Plan and an annual grant of options on January 1 of each
calendar year to acquire 6,923 shares of common stock to each non-employee
director. Each option will be exercisable in full beginning six months after the
date of grant and will expire ten years after the date of grant, unless
cancelled sooner as a result of termination of service or death, or unless such
option is fully exercised prior to the end of the option period. As of June 15,
1999, options to acquire      shares of Series D common stock were outstanding
under the Director Option Plan.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In July 1996, WebMD's subsidiary Endeavor, loaned Jeffrey T. Arnold,
Chairman and Chief Executive Officer of WebMD, $57,142 to purchase 5,000 shares
of common stock of Endeavor. This loan is evidenced by a promissory note bearing
interest at 8.5% per annum. The principal and accrued interest are payable in 24
equal installments of $2,597.43 beginning on August 1, 1996 and continuing on
the first day of each month thereafter until the indebtedness is paid in full.
In March 1997, the terms of this note were modified to provide that the
obligation to make payments on the note began on July 1, 1997 rather than August
1, 1996. The principal and interest on the note are payable in 24 equal
installments of $2,381. During Mr. Arnold's employment and through December 31,
1998, WebMD paid Mr. Arnold $52,015 in additional compensation, which Mr. Arnold
has repaid to WebMD in payment of the obligations under the above-referenced
note. In addition, WebMD paid Mr. Arnold $11,814 for tax payment obligations
incurred by Mr. Arnold as a result of this additional compensation. As of March
31, 1999, $7,141 remained outstanding under this note.

     In August 1997, J. Rex Fuqua and S. Taylor Glover, directors of WebMD,
loaned WebMD $100,000. The interest rate on these loans was 8.5% per annum. In
September 1997, WebMD repaid $100,350 to each of Mr. Fuqua and Mr. Glover as
payment in full. In connection with these loans, WebMD granted to each of
Messrs. Fuqua and Glover an option to purchase 13,846 shares of Series D common
stock at a price of $1.44 per share. These options were immediately exercisable,
remain exercisable for three years and expire upon the Healtheon-WebMD
reorganization.

     In December 1997, Premiere Technologies purchased 1,100,000 shares of
Series E common stock for $2,200,000. In connection with the stock purchase,
WebMD issued Premiere Technologies a warrant to purchase an additional 1,000,000
shares of Series E common stock for $2,000,000. In April 1998, Premiere
Technologies exercised the warrant in full. Boland T. Jones, a director of
WebMD, is the Chairman and Chief Executive Officer of Premiere Technologies and
Jeffrey T. Arnold, WebMD's Chairman and Chief Executive Officer is a director of
Premiere Technologies. WebMD also subleases the space for its corporate
headquarters and call center in Atlanta, Georgia from a wholly owned subsidiary
of Premiere Technologies. The term of the sublease ends on February 1, 2000,
with an option to renew the lease term for one additional year. The sublease
requires monthly payments by WebMD to Premiere Technologies of $36,466.50 and
the payment of additional costs and expenses. WebMD also leases equipment and
other personal property necessary for the operation of its call center from a
wholly owned subsidiary of Premiere Technologies. The term of this lease ends on
February 1, 2000, with an option to renew the lease term for one additional
year. This lease requires monthly payments by WebMD to Premiere Technologies of

                                       214
<PAGE>   225

$24,311. For three months ended March 31, 1999 and the year ended December 31,
1998, WebMD paid an aggregate of $607,775 and $364,665, respectively under this
lease.

     WebMD provides its subscribers with Premiere Technologies' enhanced
communications services. WebMD's agreement with a wholly owned subsidiary of
Premiere Technologies is effective until January 31, 2001 and contains minimum
commitments for per account and transaction payments by WebMD to Premiere
Technologies. The minimum commitments began at $10,000 per month as of September
1998. For each month following September 1998, the minimum commitments increase
by $10,000 per month to a maximum of $80,000 per month in April 1999 and
thereafter. WebMD's agreement with Premiere Technologies also provides for a
$350,000 fee for the development of the Orchestrate platform for WebMD which was
paid by WebMD in January 1998. WebMD paid a $100,000 fee in November 1998 to
Premiere Technologies to integrate the Orchestrate service and its services. In
addition, the agreement requires that WebMD spend $750,000 for joint marketing
efforts with Premiere Technologies. Premiere Technologies and WebMD entered into
an amendment to their agreement in connection with obtaining Premiere
Technologies' agreement to vote for the Healtheon-WebMD reorganization and the
WebMD merger. The amendment requires WebMD to use its best efforts to cause
Healtheon/WebMD to honor the rights and obligations under that agreement,
including the exclusivity of telecommunications services.

     In February 1998, WebMD granted to Mr. Fuqua the option to purchase 48,461
shares of Series D common stock at a price of $1.44 per share. This option
expires three years from the date of grant. WebMD granted this option in
exchange for services provided by K. Robert Draughon to WebMD while he was an
employee of Fuqua Capital Corporation, of which Mr. Fuqua is the President,
Chief Executive Officer and a stockholder.

     In June 1998, WebMD entered into strategic agreements with iXL for iXL's
provision of Web development services to WebMD. Under such agreements WebMD will
pay to iXL a minimum of $3.2 million for services over the next two years. U.
Bertram Ellis is the Chairman, Chief Executive Officer and a stockholder of iXL.
Jeffrey T. Arnold, WebMD's Chairman and Chief Executive Officer, serves on the
board of iXL, and Messrs. Fuqua and Rissanen are stockholders of iXL.

     On August 24, 1998, McKessonHBOC purchased 667,000 shares of Series A
preferred stock for $10,005,000. In connection with this investment,
McKessonHBOC also received a warrant to purchase 415,380 shares of Series A
preferred stock with an exercise price of $13.00 per share, which McKessonHBOC
exercised in April 1999. On January 27, 1999, McKesson HBOC also purchased
650,000 shares of Series C preferred stock for $13,000,000. In connection with
McKessonHBOC's initial investment, WebMD was required to issue an additional
150,000 and 57,690 shares of Series A and Series F preferred stock,
respectively, to McKessonHBOC on May 22, 1999, because WebMD failed to complete
an initial public offering by that date. WebMD has also issued a warrant to
McKessonHBOC to grant up to 183,333 shares of Series A preferred stock upon
attainment of revenue goals by McKessonHBOC. All shares held by McKessonHBOC are
subject to registration rights. In addition, McKessonHBOC has the right to
purchase 38,773 shares of Series E preferred stock, 16,745 shares of Series D
common stock and a warrant to purchase 636,980 shares of Series D common stock.
Upon the purchase by Microsoft of an additional 276,906 shares of Series E
preferred stock, McKessonHBOC will have the right to purchase 25,117 shares of
Series E preferred stock. WebMD has entered into strategic agreements with
McKessonHBOC. McKessonHBOC has agreed to market WebMD's services to its existing
customer base and to sponsor WebMD's subscriptions. These agreements also
require WebMD to provide McKessonHBOC with $5.0 million in research and
development services and to pay McKessonHBOC $5 per month per subscription
placed by McKessonHBOC. See "WebMD's Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Overview -- Promotional
arrangements." Jay P. Gilbertson, a director of WebMD and former President and
Chief Operating Officer of WebMD from December, 1998 to June 1999, was President
and Co-Chief Operating Officer and Chief Financial Officer of HBOC, a
predecessor company of McKessonHBOC, prior to November 1998. Albert J. Bergonzi
has been a director of WebMD since November 1998 and is the Group President,
Information Technology Business of McKessonHBOC.

     All sales of capital stock were made at a price per share equal to the fair
market value of such stock on the date of sale as determined by WebMD's board of
directors. Some of the transactions described above may be on terms more
favorable to officers, directors and principal stockholders than they could
obtain in a transaction with an unaffiliated party. WebMD has adopted a policy
requiring that all material transactions between WebMD and its officers,
directors or other affiliates must (1) be approved by a majority of the
disinterested members of our Board of Directors, and (2) be on terms no less
favorable to WebMD than could be obtained from unaffiliated third parties.

     WebMD's director Glenn W. Sturm is a partner in the law firm of Nelson
Mullins Riley & Scarborough, L.L.P., where he serves as Corporate Chairman and a
member of its executive committee. Nelson Mullins is currently WebMD's law firm.

     On December 1, 1998, WebMD employed Jay P. Gilbertson as President and
Chief Operating Officer. On June 4, 1999, WebMD informed Mr. Gilbertson that it
intended to terminate his employment, which the WebMD board did on June 15,
1999. WebMD and Mr. Gilbertson have not reached agreement on the terms of his
termination. Mr. Gilbertson continues to serve as a director of WebMD.

                   CERTAIN INFORMATION REGARDING MEDE AMERICA

                            MEDE AMERICA'S BUSINESS

     MEDE AMERICA is a leading provider of EDI products and services to a broad
range of providers and payers in the healthcare industry. MEDE AMERICA offers an
integrated set of EDI solutions that allows hospitals, pharmacies, physicians,
dentists and other healthcare providers and provider groups to electronically
edit, process and transmit claims, eligibility and enrollment data, track claims
submissions throughout the claims payment process and obtain faster
reimbursement for their services. In addition to offering greater processing
speed, MEDE AMERICA's EDI products and services reduce processing costs,
increase collection rates and result in more accurate data interchange. MEDE
AMERICA maintains over 540 direct connections with insurance companies, Medicare
and Medicaid agencies, Blue Cross and Blue Shield systems and other third party
payers, as well as over 500 indirect connections with additional payers through
claims clearinghouses. As of March 31, 1999, MEDE AMERICA processed
approximately 950,000 transactions per day for over 65,000 providers located in
all 50 states.

     MEDE AMERICA was formed in March 1995 through the consolidation and
subsequent spin-off of three subsidiaries of CES, in connection with the
acquisition by First Data Corporation of CES' credit card processing business.
The three subsidiaries, MEDE AMERICA, Inc., MPC, and Wellmark, which comprised
the healthcare services business of CES, historically provided EDI services to
hospitals and physicians. Since MEDE AMERICA's formation, it has expanded both
through internal growth and the acquisition of six healthcare transaction
processing businesses. As part of its strategy of providing an integrated set of
EDI products and services to a broad range of healthcare providers, MEDE AMERICA
has focused on acquisitions that provide entry into new markets or expand its
product set.

Competitive Strengths

     MEDE AMERICA believes that it has several competitive strengths which will
enable it to capitalize on the significant growth opportunities in the
healthcare EDI marketplace.

     Comprehensive Set of EDI Products and Services. MEDE AMERICA has followed a
strategy of developing or acquiring EDI products and services that may be
provided to a broad range of healthcare clients. MEDE AMERICA's products
incorporate open architecture designs and what MEDE AMERICA regard as "best of
breed" technology. Its products may be purchased as modular additions to the
client's existing data storage and retrieval system, or as part of a
comprehensive EDI processing system. These products also provide to the client
the capability and the required security to transmit or receive EDI transactions
across the Internet. They are designed to be compatible with a broad variety of
hospital, medical, pharmacy and dental practice management and billing systems.
In addition, new products can be added to respond to changing client
requirements, and the scalability of MEDE AMERICA's products permits the client
to accommodate increasing transaction volumes without requiring substantial new
investments in software and hardware.

     Broad and Diversified Client Base. MEDE AMERICA markets its products and
services to a broad range of healthcare providers including the medical market
(comprised of hospitals, clinics and physicians), the dental market (comprised
of small to medium-sized dental practice groups) and the pharmacy market (which
includes retail pharmacies -- independents and chains -- as well as pharmacy
benefits managers). In addition, it has relationships through practice
management system vendors and other intermediaries. As of March 31, 1999, MEDE
AMERICA's highly diversified client base consisted of approximately 42,000
pharmacies, 8,800 dental offices, 1,100 hospitals and clinics and 14,000
physicians.

     Direct Relationships with Providers and Payers. MEDE AMERICA has developed
over 540 direct connections with healthcare payers including Medicare and
Medicaid agencies, Blue Cross and Blue Shield systems and commercial insurance
companies. In addition, MEDE AMERICA can access over 500 additional payers
through contractual relationships with multiple claims clearinghouses. It also
has direct client relationships with providers such as hospitals, clinics,
physicians and pharmacies. The range of MEDE AMERICA's services and the extent
of its connectivity with payers provides the opportunity to

                                       220
<PAGE>   231

achieve deeper penetration of its provider base, while at the same time offering
more complete solutions to new clients.

     Focus on Client Service. MEDE AMERICA has focused on implementing a wide
range of client service and support functions. These support activities include
the use of automated client service tracking software, expanded client help desk
and account executive support functions, and extensive client feed-back
mechanisms. This focus has enhanced MEDE AMERICA's awareness of client needs and
improved its ability to respond to those needs.

     Leading Technology and Product Platforms. MEDE AMERICA recognizes the
critical role of technology and telecommunications platforms to ensure reliable
and high quality service. Over the past two years, it has invested significant
capital in new hardware and software systems resulting in an estimated threefold
increase in transaction processing capacity. MEDE AMERICA has designed its
products on a modular client/server model, using open architecture and commonly
available hardware, with redundant processing capabilities. The redundancies in
MEDE AMERICA's computing capacity and its dual-site operations enable it to
provide uninterrupted processing and data transmission with little, if any,
downtime.

     Experienced Management Team. Each member of MEDE AMERICA's senior
management team has over 15 years of experience in the information technology
and transaction processing industries and has extensive background in working
with emerging companies in the information processing industry. MEDE AMERICA
believes that the range and depth of its senior management team position it to
address the evolving requirements of its clients and to manage the growth
required to meet its strategic goals.

MEDE America's EDI Products and Services

     MEDE AMERICA's products and services enable its healthcare clients to
process and transmit transactions more efficiently and accurately, reducing
costs and increasing overall processing speed. MEDE AMERICA's EDI products
incorporate open architecture designs and what it regards as "best of breed"
technology and may be purchased as modular additions to existing data storage
and retrieval systems or as part of a comprehensive EDI processing system. They

pharmacy and dental practice management and billing systems. In addition, new

Clients

     MEDE AMERICA markets its products primarily to hospitals, pharmacies,
physicians, dentists and other healthcare providers and provider groups
(including HMOs, PPOs and healthcare practice management vendors) and process
transactions for providers in all 50 states. MEDE AMERICA believes it is one of
the largest pharmacy transaction routers in the U.S. (based on volume) serving
more than 42,000 pharmacies in various EDI capacities. MEDE AMERICA has a strong
presence in the medical market in New York, New Jersey, California, Florida,
Minnesota, and Ohio, currently providing EDI services to more than 1,100
hospitals and clinics, and 14,000 physicians. In the dental market, it serves
more than 8,800 dental offices. No single client of ours accounted for more than
3% of MEDE AMERICA's revenues in fiscal year 1998.

Sales, Marketing and Client Services

     MEDE AMERICA markets its products through a national sales and marketing
organization consisting of 95 associates organized according to market, client
type and product category. It also has a client services organization consisting
of 69 associates dedicated to help desk and client support functions. A
significant component of compensation for all sales personnel is performance
based, although it bases quotas and bonuses on a number of factors in addition
to actual sales, such as client satisfaction and collection of receivables.

     MEDE AMERICA's marketing efforts include direct sales, telesales, strategic
partnerships with healthcare vendors, trade shows, direct marketing,
telemarketing, the Internet, and specific advertising and marketing campaigns
where appropriate. In the medical and pharmacy markets, MEDE AMERICA's current
strategic business alliances include relationships with some of the country's
largest hospitals, hospital networks, hospital information systems vendors,
practice management software vendors, pharmacy chains, healthcare organizations
and payers. MEDE AMERICA also maintain strategic alliances with certain state
Medicaid programs.

     MEDE AMERICA's strategic alliances with vendors, distributors and dealers
of practice management software have played an important role in building
relationships with individual and small groups of physicians, pharmacies and
dentists. These companies promote MEDE AMERICA's EDI products as modular
additions to their practice management software. MEDE AMERICA has also won
endorsements from 18 state dental associations, representing nearly half of all
dentists in practice today. Its sales channels include targeting dental practice
management companies and payer-driven programs aimed at their network providers.

Research and Development

     As of March 31, 1999, MEDE AMERICA employed 87 people in the areas of
product design, research and development, and 41 people in the areas of quality
assurance and technical support. MEDE AMERICA's product development strategy is
focused on continuous enhancement of its existing products to increase their
functionality and ease of use, and the development of new products for
additional EDI transactions and telecommunications offerings.

     In MEDE AMERICA's 1996, 1997 and 1998 fiscal years, research and
development expenditures totaled $2,132,000, $3,278,000 and $3,941,000,
respectively. For the nine months ended March 31, 1999, research and development
expenditures totaled $3,379,000. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

Technology and Operations

     Since the beginning of fiscal 1996, MEDE AMERICA has spent over $5.0
million on new hardware and software data center improvements. MEDE AMERICA
estimates that it is currently operating at approximately one-third of its
operating capacity.

Advanced Open Architecture

     MEDE AMERICA's products and applications offer clients the benefits of an
"open architecture" EDI system. As a result, a client's system can expand or
change without incurring significant incremental capital expenditures for
hardware or software. The open architecture of MEDE AMERICA's systems also
improves reliability and connectivity, and facilitates the cross selling of its
products, in part because of the following characteristics:

     - SCALABILITY. MEDE AMERICA's systems are designed to take full advantage
       of the client/server environment, UNIX operating systems and Redundant
       Array of Inexpensive Disks ("RAID") technology, allowing clients to
       expand MEDE AMERICA's processing capacity.

     - MODULARITY. MEDE AMERICA's client/server systems has been developed with
       discrete functionality that can be replicated and utilized with
       additional hardware. This modularity enables us to optimize application
       and hardware performance.

     - REDUNDANCY. The implementation of a dual site, geographically dispersed
       On-Line Transaction Processing ("OLTP") switch (Twinsburg, Ohio and
       Mitchel Field, New York) and RAID technology for batch processing
       significantly reduces the risk of business interruption. Each of its
       sites is designed to be entirely self-supporting.

     - OPEN SYSTEMS. Through the use of an open systems architecture, MEDE
       AMERICA can add new functionality to applications without re-designing
       its applications or architecture.

     - INDUSTRY STANDARDS. Through the adoption and active use of pertinent
       standards for healthcare EDI processing, MEDE AMERICA can support client
       and payer processing requirements and provide standard interfaces to
       other EDI processing organizations.

     - EASE OF USE. MEDE AMERICA's products are either Windows-based or
       GUI-based and function in UNIX, Novell and Windows NT operating
       environments, thereby enhancing ease of use by MEDE AMERICA's clients.

Competition

     Competition in the market for MEDE AMERICA's products and services is
intense and is expected to increase. The EDI market is characterized by rapidly
changing technology, evolving user needs and frequent introduction of new
products. Many of MEDE AMERICA's competitors and potential competitors have
significantly greater financial, technical, product development, marketing and
other resources and market recognition than it does. In addition, many of its
competitors also currently have, or may develop or acquire, substantial
installed client bases in the healthcare industry. As a result of these factors,
MEDE AMERICA's competitors may be able to respond more quickly to new or
emerging technologies, changes in client requirements and political, economic or
regulatory changes in the healthcare industry, and may be able to devote greater
resources to the development, promotion and sale of their products than it can.

     MEDE AMERICA's principal competitors include:

        National Data Corporation, Envoy Corporation and SSI, Inc. in claims
        processing and eligibility verification;

        QuadraMed Corporation in claims processing;

        Medifax, Inc. and HDX Healthcare Data Exchange Corporation in
        eligibility verification; and

        Envoy Corporation in the dental market.

MEDE AMERICA also may face potential competition from other companies not
currently involved in healthcare electronic data transmission, which may enter
the market as EDI becomes more established. MEDE AMERICA believes that existing
and potential clients in the healthcare EDI market evaluate the products and
services of competing EDI providers on the basis of the compatibility of the
provider's

                                       224
<PAGE>   235

software, cost, ease of installation, the range of applications available, the
quality of service and the degree of payer connectivity.

Employees

     As of March 31, 1999, MEDE AMERICA employed 406 people, including 113 in
operations, 95 in sales and marketing, 69 in client services, 87 in research and
development, 32 in finance and administration and ten in corporate. None of MEDE
AMERICA's employees is represented by a union or other collective bargaining
group. MEDE AMERICA believes its relationship with its employees to be
satisfactory.

Intellectual Property

     MEDE AMERICA considers its methodologies, computer software and many of its
databases to be proprietary. MEDE AMERICA relies on a combination of trade
secrets, copyright and trademark laws, contractual provisions and technical
measures to protect its rights in various methodologies, systems, products and
databases. MEDE AMERICA has no patents covering its software technology. Due to
the nature of its application software, MEDE AMERICA believes that patent and
trade secret protection are less significant than its ability to further
develop, enhance and modify its current products. However, any infringement or
misappropriation of its proprietary software and databases could disadvantage
MEDE AMERICA in its efforts to retain and attract new clients in a highly
competitive market and could cause us to lose revenues or incur substantial
litigation expense. MEDE AMERICA seeks to protect its proprietary information
through nondisclosure agreements with its consultants, clients and potential
clients, and limits access to, and distribution of, its proprietary information.

     Substantial litigation regarding intellectual property rights exists in the
software industry, and MEDE AMERICA expects that software products may be
increasingly subject to third-party infringement claims as the number of
competitors in MEDE AMERICA's industry segment grows and the functionality of
products overlaps. Although MEDE AMERICA believes that its products do not
infringe on the intellectual rights of others, there can be no assurance that
such a claim will not be asserted against it in the future, or that a license or
similar agreement will be available on reasonable terms in the event of an
unfavorable ruling on any such claim.

Legal Proceedings

     In June 1995, MEDE AMERICA acquired substantially all of the assets of
Latpon for a purchase price of $2,470,000, plus the assumption of approximately
$963,000 of liabilities. On June 6, 1998, Curtis J. Oakley filed a complaint
with the Supreme Court of the State of New York, County of Nassau asserting
multiple causes of action against several persons, including a cause of action
naming us as a defendant, based on his alleged ownership of a 22% interest in
Latpon. According to the complaint, Mr. Oakley's claim against us is for $2
million or such other amount as may be equivalent to the present value of his
alleged ownership interest in Latpon's predecessor. MEDE AMERICA believes that
it is fully indemnified by the former owners of Latpon under the Latpon
acquisition agreement against any costs or damages arising from this claim. By
letter dated July 10, 1998, one of the former owners of Latpon confirmed that he
would indemnify us in accordance with the terms of the acquisition agreement. On
August 25, 1998, MEDE AMERICA filed a motion to dismiss this claim. That motion
was granted on January 27, 1999. On May 14, 1999, the plaintiff filed a notice
of appeal.

     On May 14, 1999, National Data Corporation, or NDC filed suit against MEDE
America and its subsidiary Healthcare Interchange, Inc., or HII, which was
acquired by the Company in October 1998, in the Superior Court of DeKalb County,
Georgia, alleging, among other things, unjust enrichment, breach of contract,
misappropriation of trade secrets and interference with contract. The action
arises out of an alleged breach of a license agreement entered into between HII
and Healthcare Affiliated Services, Inc., which was subsequently acquired by
NDC. The agreement provided for the termination of the license in the event HII
was sold or merged into an entity other than RightCHOICE Managed Care, Inc.,
formerly a 50% shareholder of HII. The complaint seeks to recover $5 million in
compensatory damages, plus punitive damages and litigation expenses, including
attorneys' fees. On April 1, 1999, NDC had issued a demand letter to the Company
demanding, among other things, that HII cease using the licensed software and
assign to NDC certain agreements with hospital and physician clients. On April
9, 1999, NDC offered to license the software retroactively to HII as of the
acquisition date and sell the source code to HII for $2.3 million. A total of 88
hospital clients, and approximately 700 physician clients of HII, providing
monthly revenue to HII of approximately $200,000, utilize the software licensed
pursuant to the agreement. Because the software is not Year 2000 compliant and
migration of the hospital and physician clients to other software is underway in
any event, HII rejected the offer. Further negotiations with NDC were
unsuccessful in reaching what the Company believes to be a fair resolution of
the issue. The Company has responded to NDC's complaint, denying the
allegations, and intends to vigorously contest the action.

              MEDE AMERICA MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     MEDE AMERICA is a leading provider of electronic data interchange, called
EDI, products and services to a broad range of providers and payers in the
healthcare provider industry. MEDE AMERICA's integrated set of EDI solutions and
services allows hospitals, pharmacies, physicians, dentists and other healthcare
providers and provider groups to electronically edit, process and transmit
claims, eligibility and enrollment data, track claims submissions throughout the
claims payment process and obtain faster reimbursement for their services.
Currently, MEDE AMERICA processes approximately 950,000 transactions per
business day for over 65,000 providers located in all 50 states.

     MEDE AMERICA was formed in March 1995 through the consolidation and
subsequent spin-off of three subsidiaries of CES, in connection with the
acquisition by First Data Corporation of CES' credit card processing business.
The three subsidiaries, MEDE AMERICA, Inc., MPC and Wellmark, which comprised
the healthcare services business of CES, historically provided EDI services to
hospitals and physicians. Their combined financial results were reflected in the
fiscal 1995 financial statements on a full year basis.

     Since its formation, MEDE AMERICA has expanded both through internal growth
and the acquisition of six healthcare transaction processing businesses. As part
of its strategy of providing an integrated set of EDI products to a broad range
of healthcare providers, MEDE AMERICA has focused on acquisitions that provide
entry into new markets or expand its product set. MEDE AMERICA has accounted for
all acquisitions under the purchase method of accounting. MEDE AMERICA has
actively pursued the integration of its acquisitions and, in the process, has
either divested, closed or modified various operations of the acquired entities
in order to eliminate non-core or redundant operations and achieve cost savings
and operating efficiencies. These integration activities impacted MEDE AMERICA's
financial results in the fiscal years ended June 30, 1995, 1996, 1997 and 1998
and are ongoing.

(1) Represents date acquired by CES.

     In March 1995, MEDE AMERICA's largest stockholder acquired all of the
outstanding shares of MEDE OHIO (formerly known as General Computer Corporation)
for a cash purchase price of approximately $22,593,000, including transaction
expenses. The largest stockholder subsequently merged MEDE OHIO into MEDE
AMERICA. The purchase price MEDE AMERICA paid for MEDE OHIO to its largest
stockholder was equal to the purchase price paid by the largest stockholder.
MEDE OHIO develops EDI systems for the pharmacy market and provides transaction
switching/routing services. At the time of its acquisition, MEDE OHIO had been
incurring significant losses for over two years and was in very poor financial
condition. The acquisition was accounted for under the purchase method and MEDE
AMERICA recorded total intangible assets of $25,814,000, consisting of $892,000
of software (which was completed and not in-process at the time of the
acquisition), $2,527,000 of client lists and $22,395,000 of goodwill. During
fiscal year 1996, MEDE AMERICA wrote-down $9,965,000 of costs relating to client
lists and related allocable goodwill due to a loss of approximately 25% of the
acquired MEDE OHIO client base. The loss of this significant portion of MEDE
OHIO's client base was primarily due to problems MEDE AMERICA experienced in the
post-merger integration of MEDE OHIO's operations into MEDE AMERICA's
operations. This post-merger integration process took place during the same
general time period in which MEDE AMERICA was spun-off from CES and a new
management team was installed at MEDE AMERICA. MEDE AMERICA is generally
amortizing the software over three years and the remaining value of client lists
is being amortized over five years. The goodwill is being amortized over 20
years.

     In June 1995, MEDE AMERICA acquired substantially all of the assets of
Latpon for a cash purchase price of approximately $2,470,000, plus the
assumption of approximately $963,000 of liabilities (primarily long-term debt).
Latpon, a developer of claims processing software, provided EDI transaction
processing services to hospitals and hospital-based physician groups. Latpon
also provided electronic and manual business office administrative services. The
acquisition was accounted for under the purchase

                                       230
<PAGE>   241

method and MEDE AMERICA recorded total intangible assets of $2,291,000,
consisting of $993,000 of software and client lists and $1,298,000 of goodwill.
MEDE AMERICA is generally amortizing the software over five years and are
amortizing the client lists and goodwill over five years and 20 years,
respectively.

     In October 1995, MEDE AMERICA acquired two commonly-owned companies, EC&F,
an all payer EDI dental claims processor, and Premier, a dental practice
management software vendor. The acquisitions were funded with an initial cash
payment of $4,050,000, including transaction expenses, and contingent earn-out
payments based on the achievement of certain EBITDA growth targets by the EC&F
business over three one-year periods ending on September 30, 1998. MEDE AMERICA
recorded expenses of $538,000 during fiscal year 1996 relating to the first such
period and an aggregate $2,301,000 during fiscal year 1997 primarily relating to
the second and third such periods. At the conclusion of the earn-out period, it
was determined that no additional earn-out payments would be required. The
acquisitions of EC&F and Premier were accounted for under the purchase method
and MEDE AMERICA recorded total intangible assets of $4,350,000, consisting of
$764,000 of software, and $3,586,000 of goodwill. MEDE AMERICA generally is
amortizing the software over three years and are amortizing the goodwill over 20
years. MEDE AMERICA sold Premier in January 1997 for a cash payment of $388,000.
There was no gain or loss on the sale of Premier.

     In February 1997, MEDE AMERICA acquired certain assets of TCS, a provider
of pharmacy switching and PBM transaction processing systems and services for
pharmacies and eligibility verification services for physicians, for a total
cash payment of $11,465,000, including transaction expenses. The acquisition was
accounted for under the purchase method and MEDE AMERICA recorded total
intangible assets of $11,065,000, consisting of $1,556,000 of in-process
research and development, $2,984,000 of software and $6,525,000 of goodwill. As
of the date of the acquisition, MEDE AMERICA wrote off the acquired in-process
research and development which had not reached technological feasibility and had
no alternative future use. MEDE AMERICA generally is amortizing the software
over three years and are amortizing the goodwill over seven years.

     The in-process research and development acquired from TCS consisted of
advanced Windows software technology for PC and client server platforms for
healthcare EDI transactions. Products under development included: (1) a plan
member eligibility verification product for workers compensation; (2) a medical
claims processing system to meet the HCFA 1500 EDI industry standard; and (3) a
switching system for internet claims from retail pharmacies. At the time of the
acquisition, MEDE AMERICA estimated that continued development activities for
six months to one year resulting in additional estimated research and
development costs of $460,000 would be required in order to prove feasibility
and bring the project to commercial viability. It was the opinion of management
that such projects had an above average probability of successful completion and
could contribute to revenue, profit and cash flow within 18 to 24 months from
the date of purchase. At this time, all three projects are substantially
complete. However, any or all of these projects could fail to produce an
economic gain. Such failure, if encountered, would not affect MEDE AMERICA's
current product set and financial results, but would decrease its opportunities
for growth. Estimated costs to complete the acquired in-process research and
development projects as of the date of acquisition were as follows:

     Prior to the consummation of the acquisition, TCS had incurred development
costs of $67,000, $125,000 and $56,000, respectively, for the workers
compensation eligibility product, HCFA 1500 and the internet pharmacy claims
product, the three in-process research and development projects shown above.

     MEDE AMERICA determined the value of the purchased in-process technologies
by estimating the projected net cash flows related to each of the in-process
products. The resulting net cash flows were then discounted back to their net
present values. The amount of the write-off of in-process research and
development costs was then limited to the portion allocable to pre-acquisition
development costs incurred by TCS versus post-acquisition costs incurred by us.
The net cash flows were based on management's estimates of the costs necessary
to complete the development of the products, the revenues that would be earned
after commercial availability and the estimated operating expenses associated
with those revenues. The projections were based on the following principal
assumptions:

     For the workers compensation eligibility product, the projections assumed
commercial availability in January 1998 and revenue growth from $431,000 in
fiscal 1998 to $1.3 million in fiscal 2002, an annual rate increase of
approximately 25%. For HCFA 1500, the projections assumed commercial
availability in March 1998. It was assumed that revenues from the HCFA 1500
product would grow from $1.4 million in fiscal 1998 to $5.5 million in fiscal
2002, increasing at an annual rate of 50% in the first year of commercial
availability, 35% in the second year and at a rate of 25% per year thereafter.
For the internet pharmacy claims product, the projections assumed commercial
availability in December 1997. It was assumed that revenues from the internet
pharmacy claims product would grow from $41,000 in fiscal 1997 to approximately
$3.2 million in fiscal 2002, increasing at an annual rate of approximately 35%
in the first year of commercial availability, 30% in the second year and at a
rate of 25% per year thereafter.

     In all three cases, post-development operating expenses, including sales,
advertising and promotion and general and administrative costs, were projected
to grow at the rate of 10% per year between fiscal 1999 and 2002. No significant
synergies were projected for any of the three in-process products because MEDE
AMERICA had no comparable products in the market or in development and no
penetration in the products' prospective user bases.

     The projected net cash flows for the in-process products were discounted to
their present values using a discount rate of 18%. Such discount rate was
composed of two factors: MEDE AMERICA's estimated weighted average cost of
capital (the rate of return an investment would have to generate in order to
provide the required rate of return to MEDE AMERICA's equity and long-term debt
capital), which was calculated to be approximately 13%, and a 5% risk factor
reflecting the uncertainty of successful completion and market acceptance of the
in-process products. Together, the weighted average cost of capital and risk
factor yield a discount factor of 18%. MEDE AMERICA used a 13% discount rate
factor to value fully developed software, as it faces substantially the same
risks as the business as a whole. The 5% risk factor reflected the fact that the
in-process products did not involve complex or innovative technologies, and
primarily reflected the risk of market acceptance once the developed products
were released to customers.

     Since the TCS acquisition, all three in-process products have been
completed and two are in the early stages of commercialization. As of March 31,
1999, none of these products had generated significant revenues, and, given the
results of MEDE AMERICA's marketing efforts to date, MEDE AMERICA currently
believes that the revenues derived from these three products will be lower than
projected.

     The market for the workers compensation eligibility product has been less
receptive than had been anticipated and this product did not generate any
revenues as of March 31, 1999. However, MEDE AMERICA believes that, over time
and with increased marketing effort, this product will achieve commercial
viability.

     The HCFA 1500 product experienced roll out delays and is expected to be
commercially introduced in the Spring of 1999. MEDE AMERICA believes that, in
time, this product will achieve commercial viability.

                                       232

     The internet pharmacy product is the only one of the three in-process
products acquired from TCS that had generated revenues by the end of fiscal
1998. However, the revenues produced were approximately 22% of the revenues
projected for it at the time of the acquisition. The commercial introduction of
this product was adversely affected by recent revisions in regulatory standards
which limit the use of the internet to process pharmacy claims. MEDE AMERICA is
currently processing transactions with this product for a small number of
pharmacy clients.

     Although any or all of these projects could fail to generate significant
returns for MEDE AMERICA and such failure could render the TCS acquisition less
valuable to us than had been anticipated, such failure would not affect MEDE
AMERICA's current set of products or, in MEDE AMERICA's opinion, have a material
impact on its results of operations or overall financial condition.

     In November 1997, MEDE AMERICA acquired certain assets and assumed certain
liabilities of Stockton, a provider of PBM transaction processing systems and
related services for the pharmacy market. Stockton was purchased for an initial
cash payment of $10,674,000 including transaction expenses, and a contingent
earnout payment based upon the achievement of certain revenue growth targets.
Based on revenues recorded through September 30, 1998 by Stockton, MEDE AMERICA
has accrued additional contingent consideration of $2,022,000 as of September
30, 1998 which was treated as additional purchase price and was, therefore,
added to goodwill. Based upon revenue generated, MEDE AMERICA made a payment of
approximately $1.8 million to the selling shareholders on February 23, 1999.
Certain additional funds totalling approximately $100,000 were placed in escrow
as being in dispute pursuant to the earn-out provisions. Depending on the
outcome of litigation between the selling shareholders of Stockton and one of
its customers, those funds will be released accordingly. The acquisition was
accounted for under the purchase method and MEDE AMERICA recorded total
intangible assets of $10,414,000, consisting of $2,133,000 of software and
client lists and $8,281,000 of goodwill. MEDE AMERICA is generally amortizing
the software over five years and is amortizing the client lists and goodwill
over five years and 20 years, respectively.

     In October 1998, MEDE AMERICA acquired HII, a provider of EDI transaction
processing services to hospitals and physician groups in Missouri, Kansas and
Illinois. Prior to the purchase of HII, Intercare and Telemedical, two unrelated
healthcare services divisions, were divested from HII in separate transactions.
MEDE AMERICA did not acquire such businesses or any proceeds from the
disposition of those businesses. HII was purchased for a total cash payment of
approximately $11,718,000, including transaction expenses. The acquisition was
accounted for under the purchase method and MEDE AMERICA recorded total
intangible assets of approximately $11,013,000, consisting of $2,713,000 of
client lists and approximately $8,300,000 of goodwill. MEDE AMERICA is
amortizing the client lists over five years and goodwill over 20 years.

Medic Agreement

     On July 17, 1998, MEDE AMERICA entered into a Transaction Processing
Agreement with Medic Computer Systems, Inc., a subsidiary of Misys plc that
develops and licenses software for healthcare providers, principally physicians,
MSOs and PPMs. Under the processing agreement, MEDE AMERICA will undertake
certain software development obligations, and on July 1, 1999, it will become
the exclusive processor (subject to certain exceptions) of medical reimbursement
claims for Medic's subscribers submitted to payers with whom MEDE AMERICA has or
establishes connectivity. Under the processing agreement, MEDE AMERICA will be
entitled to revenues to be paid by payers (in respect of which a commission is
payable to Medic) as well as fees to be paid by Medic. The processing agreement
sets forth detailed performance criteria and development and implementation
timetables; inability to meet these criteria may result in financial penalties
or give Medic a right to terminate this agreement. The agreement may also be
terminated by Medic within a period of eight months after a change of control of
the Company. The processing agreement is for a fixed term of five years, with
annual renewals thereafter.

     Contemporaneously, to ensure a close working relationship between the
parties, on July 17, 1998 the Company granted to Medic a warrant to acquire
1,250,000 shares of the Company's common stock, at a

                                       233
<PAGE>   244

per share exercise price equal to the price of the common stock to the public in
the IPO or, in the event that the IPO was not completed by March 31, 1999 at an
exercise price equal to $8 per share. The Medic warrant contains customary
weighted average antidilution provisions. The Medic warrant vests over a two
year period (subject to acceleration upon a change of control) and may be
exercised up to five years after issuance. The Medic warrant was valued at
$3,925,000 using the Black-Scholes Option Pricing Model and is recorded in other
assets. The Medic warrant is being amortized over the life of the processing
agreement, five years. MEDE AMERICA and certain principal stockholders have
agreed that following the completion of the IPO and until the earlier of the
termination of the processing agreement or the disposition by Medic and its
affiliates of at least 25% of the shares of common stock issuable under the
Medic warrant, Medic shall have the right to designate one director to MEDE
AMERICA's board of directors. Medic named a designee effective February 12,
1999.

Revenues

     Revenues are derived from the sale of transaction processing products and
services primarily on a fee-for-transaction basis. Transaction fees vary
depending upon transaction type and service provided. MEDE AMERICA currently
receives fees from providers for the majority of its transactions including
claims processing, eligibility verification, claims switching, pharmacy script
processing and tracking and Medicaid enrollment. It also receives fees from
payers for the transmission of electronic claims and formulary payments from
pharmaceutical manufacturers relating to its PBM script processing and
management reporting services. These transaction-based revenues comprise the
predominant portion of MEDE AMERICA's total revenues and tend to be recurring.
Other revenue is derived from one-time payments related to installation and
implementation services, software license fees and EDI systems equipment sales.
See "Business -- Set of EDI Products and Services."

     Transaction-based revenues and related formulary services revenues (if
applicable), which collectively constitute the majority of MEDE AMERICA's total
revenues, are recognized at the time the transactions are processed and the
services are provided. Revenues associated with software support and
implementation fees, each constituting less than 3% of MEDE AMERICA's revenues
for the fiscal year ended June 30, 1998 and the nine months ended March 31,
1999, are recognized ratably over the contract period or as the service is
provided. Revenue from licensing of software, which also constitutes less than
3% of its total revenues for the fiscal year ended June 30, 1998 and the nine
months ended March 31, 1999, is recognized upon installation if it is determined
that MEDE AMERICA has no significant remaining obligations and collectibility of
the resulting receivable is considered probable.

Operating Expenses

     Operations Expense. Operations expense consists of:

     - data and voice telecommunications expense,

     - salaries and benefits for operations employees, and

     - other costs associated with transaction processing and services provided
       to clients, such as

       -- network and telecommunications,

       -- maintenance,

       -- computer operations, and

       -- systems administration, facilities and other additional indirect
          expenses.

Since 1996, operations expense as a percentage of revenues and operations
expense per transaction have declined as a result of MEDE AMERICA's integration
and restructuring efforts and increased operating leverage. Restructuring
charges recorded in connection with its integration activities have resulted in
variability in its quarterly operating results.

                                       234
<PAGE>   245

     Sales, Marketing and Client Services Expense. Sales, marketing and client
services expense consists primarily of salaries, benefits, commissions and
related indirect costs and expenditures for marketing programs, trade shows,
advertising, help desk software and related client communications. As MEDE
AMERICA continues to implement its growth strategy, sales, marketing and client
services expenses are expected to continue to increase.

     Research and Development Expense. Research and development expense consists
primarily of salaries, benefits and related indirect expenses associated with
the design, research and development of new products and enhancements to
existing current products. The development of new software products and
enhancements to existing software products are expensed as incurred until
technological feasibility has been established. After technological feasibility
has been established, any additional software development costs are capitalized
in accordance with Statement of Financial Accounting Standards (referred to as
"SFAS") No. 86, "Accounting For the Cost of Computer Software To Be Sold, Leased
or Otherwise Marketed." Amortization of purchased software and technology and of
capitalized software development costs is provided on a product-by-product basis
at the greater of the amount computed using (a) the ratio of current revenues
for a product to the total of current and anticipated future revenues or (b) the
straight-line method over the remaining estimated economic life of the product.
Generally, an original estimated economic life of three to five years is
assigned to purchased software and technology and an original estimated economic
life of five years is assigned to capitalized software development costs.
Amortization begins in the period in which the related product is available for
general release to customers. During the fiscal year ended June 30, 1998 and the
nine months ended March 31, 1999, MEDE AMERICA capitalized $462,000 and
$820,000, respectively, of software development costs for projects for which
technological feasibility has been established but were not yet available for
client release. Prior to July 1, 1997, MEDE AMERICA did not have any software
development projects for which significant development costs were incurred
between the establishment of technological feasibility and general client
release of the product. MEDE AMERICA believes that the development of enhanced
and new product offerings are essential to remaining competitive and it expects
that development expenses will increase in the future.

     General and Administrative Expense. General and administrative expense
primarily consists of salaries, benefits and related indirect costs for the
administrative, executive, finance, legal, human resources and internal systems
personnel, as well as accounting and legal fees. As MEDE AMERICA implement its
growth strategy, general and administrative expenses are expected to increase.

     Depreciation and Amortization Expense. MEDE AMERICA depreciates the cost of
its tangible capital assets on a straight-line basis over the estimated economic
life of the asset: three to five years for computer equipment, five years for
furniture and fixtures, and 20 to 25 years for buildings and improvements.
Acquisition-related intangible assets, which include the value of software and
client lists, are amortized based on the estimated useful economic life of the
asset at the time of acquisition, and therefore will vary among acquisitions.
MEDE AMERICA recorded amortization expense relating to goodwill and other
intangible assets of $3,708,000 and $5,064,000 during the fiscal years ended
June 30, 1997 and 1998, respectively, and 4,927,000 during the nine months ended
March 31, 1999.

     Subsequent to the issuance of its consolidated financial statements for the
fiscal year ended June 30, 1998, MEDE AMERICA determined that it was necessary
to revise the valuation of the write-off of in-process research and development
incurred in connection with the TCS acquisition in February 1997. As a result,
its financial statements for the fiscal years ended June 30, 1997 and 1998 and
the nine months ended March 31, 1998 have been restated from the amounts
previously reported in order to reflect the effects of the adjustment to the
write-off of in-process research development. See Note 13 of MEDE AMERICA notes
to consolidated financial statements.

Nine Months Ended March 31, 1999 Compared to Nine Months Ended March 31, 1998

     Revenues in the nine months ended March 31, 1999 were $39.8 million,
compared to $30.2 million in the corresponding period of fiscal 1998,
representing an increase of 32%. The increase was primarily attributable to
growth of the existing business and to incremental revenue from the acquisition
of The Stockton Group in November 1997 and HII in October 1998. The Company
processed 227.8 million transactions in the nine months ended March 31, 1999,
compared to 171.0 million transactions processed in the corresponding period of
fiscal 1998, representing an increase of 33%. The increase resulted from the
incremental transactions from the acquisition of Stockton and HII, the addition
of new clients and the increased transaction volume from existing clients. The
average price per transaction received by MEDE AMERICA for the nine months ended
March 31, 1999 declined by 5%, compared with the corresponding period of the
prior fiscal year, as a result of a relatively higher proportion of lower-priced
Pharmacy division switching transactions compared to the other divisions'
higher-priced transactions, and a greater portion of transactions that were
processed under contracts with volume-based pricing terms, partially offset by
the acquisition of HII and its relatively higher priced transactions when
compared to MEDE AMERICA's average in the three and nine month periods.

     Operating Expenses

     Operations expense was $5.3 million and $15.0 million in the three and nine
months ended March 31, 1999, respectively, compared to $4.3 and $12.5 million in
the corresponding periods of fiscal 1998, representing increases of 24% and 20%,
respectively. As a percentage of revenues, operations expense decreased from 38%
and 41% in the three and nine months ended March 31, 1998, respectively, to 36%
and 38% in the corresponding periods of fiscal 1999. The increase in operations
expense was primarily due to the acquisition of Stockton in November 1997 and
HII in October 1998, and to the higher volume of transactions processed. The
decrease in operations expense as a percentage of revenues was primarily due to
operations leverage from systems consolidation for the recent acquisitions, the
effects of ongoing cost reduction programs, and to a lesser extent, the impact
of the divested operations, which results were included in the fiscal 1998
periods but not the fiscal 1999 periods.

                                       236
<PAGE>   247

     Sales, marketing and client services expense was $3.3 million and $9.5
million in the three and nine months ended March 31, 1999, respectively,
compared to $3.0 million and $7.8 million in the corresponding periods of fiscal
1998, representing increases of 13% and 22%, respectively. As a percentage of
revenues, sales, marketing and client services expense decreased from 27% and
26% for the three and nine months ended March 31, 1998, respectively, to 23% and
24% in the corresponding periods of 1999. The increase in sales, marketing and
client services expense was primarily due to the inclusion of the Stockton and
HII acquisitions. The decrease in sales, marketing and client services expense
as a percentage of revenues was primarily due to operations leverage from
consolidation of recent acquisitions.

     Research and development expense was $1.1 million and $3.4 million in the
three and nine months ended March 31, 1999, respectively, compared to $1.0
million and $2.9 million in the corresponding periods of fiscal 1998,
representing increases of 9% and 17%, respectively. As a percentage of revenues,
research and development expense decreased from 9% and 10% for the three and
nine months ended March 31, 1998, respectively, to 8% in the corresponding
periods of fiscal 1999. MEDE AMERICA capitalized $354,000 and $820,000 of
software development costs in the three and nine months ended March 31, 1999,
respectively, compared to $125,000 and $319,000 in the corresponding periods of
fiscal 1998. The increases in research and development costs in the fiscal 1999
periods were primarily due to development of new and enhanced EDI transaction
products and services, development associated with major customer contracts
currently expected to roll out in calendar 1999 and the establishment of
additional direct payor connections. In addition, Year 2000 compliance
expenditures amounted to $97,000 and $609,000 in the three and nine months ended
March 31, 1999, respectively, compared to $106,000 in both of the corresponding
periods of fiscal 1998.

     General and administrative expense was $1.6 million and $4.1 million in the
three and nine months ended March 31, 1999, respectively, compared to $1.1
million and $3.3 million in the corresponding periods of fiscal 1998,
representing an increase of 25% and 37%, respectively. As a percentage of
revenues, general and administrative expense increased from 10% for the three
months ended March 31, 1998 to 11% in the corresponding period of fiscal 1999
and decreased from 11% for the nine months ended March 31, 1998 to 10% in the
corresponding period of 1999.

     Depreciation and amortization expense was $2.4 million and $6.5 million in
the three and nine months ended March 31, 1999, respectively, compared to $1.9
million and $5.2 million in the corresponding periods of fiscal 1998,
representing increases of 28% and 23%, respectively. The increase in
depreciation and amortization expense was primarily attributable to the Stockton
and HII acquisitions. As a percentage of revenues, depreciation and amortization
expense decreased to 16% in the three and nine months ended March 31, 1999 from
17% in the three and nine months ended March 31, 1998.

Year Ended June 30, 1998 Compared to Year Ended June 30, 1997

     Revenues

     Revenues for the fiscal year ended June 30, 1998 were $42.3 million
compared to $35.3 million in fiscal 1997, representing an increase of 20%. The
increase was primarily attributable to incremental revenue from the acquisitions
of TCS and Stockton in February 1997 and November 1997, respectively, and to the
growth of the existing business, partially offset by the loss of revenues from
operations that were divested.

     MEDE AMERICA processed 234 million transactions in the fiscal year ended
June 30, 1998, compared to 161 million transactions processed in fiscal 1997,
representing an increase of 45%. The increase resulted from the addition of new
clients, increased transaction volume from existing clients and the acquisitions
of TCS and Stockton. The average price per transaction MEDE AMERICA received in
fiscal 1998 declined by 13% from 1997, as a result of the greater proportion of
transactions processed under contracts with volume-based terms and pricing and a
larger proportion of lower-priced eligibility verification transactions as a
result of the acquisition of TCS.

     Operating Expenses

     Operations expense was $17.0 million for the fiscal year ended June 30,
1998 compared to $16.8 million in fiscal 1997, representing an increase of 1%.
As a percentage of revenues, operations expense decreased from 48% in fiscal
1997 to 40% in fiscal 1998. The containment of operations expense in fiscal 1998
was a result of ongoing cost reduction programs, systems consolidation for
recent acquisitions and the impact of the divested operations, which results are
included in fiscal 1997 but not in fiscal 1998.

     Sales, marketing and client services expense was $10.8 million for the
fiscal year ended June 30, 1998 compared to $8.8 million in fiscal 1997,
representing an increase of 23%. As a percentage of revenues, sales, marketing
and client services expense was 25% for each such fiscal year. The increase in
such expenses was primarily due to the inclusion of TCS and Stockton in the
results of operations for the fiscal year ended June 30, 1998. The increase in
such expenses, to a lesser extent, was due to increases in expenses relating to
the hiring of new employees for client support and help desk service, the
installation of help desk tracking software and resources devoted to telesales.

     Research and development expense was $3.9 million for the fiscal year ended
June 30, 1998 compared to $3.3 million in fiscal 1997, representing an increase
of 20%. As a percentage of revenues, research and development expense was 9% for
each such fiscal year. MEDE AMERICA capitalized $462,000 of software development
costs in fiscal 1998; however, no software development costs were capitalized in
fiscal 1997. Prior to July 1, 1997, MEDE AMERICA did not have any software
development projects for which significant development costs had been incurred
between the establishment of technological feasibility and general client
release of the product.

     General and administrative expense was $4.9 million for the fiscal year
ended June 30, 1998 compared to $5.3 million in fiscal 1997, representing a
decrease of 8%. As a percentage of revenues, general and administrative expense
decreased from 15% in fiscal 1997 to 12% in fiscal 1998. This decrease was
primarily a result of cost controls and the consolidation and integration
activities to MEDE AMERICA's recent acquisitions.

     Depreciation and amortization expense was $7.1 million for the fiscal year
ended June 30, 1998 compared to $5.5 million in fiscal 1997, representing an
increase of 31%. As a percentage of revenues, depreciation and amortization
expense increased from 15% in fiscal 1997 to 17% in fiscal 1998. These increases
reflect the increased amortization expense related to the acquisitions of TCS in
February 1997 and Stockton in November 1997.

     There were no acquisition-related expenses for the fiscal year ended June
30, 1998, as compared to $3.9 million of such expenses in fiscal 1997. Included
in the amount for fiscal 1997 was a $1.6 million write-off related to in-process
research and development from the acquisition of TCS (for software that had not
achieved technological feasibility and had no alternative use), and a contingent
earnout charge of $2.3 million recorded by MEDE AMERICA in connection with the
EC&F purchase agreement. In addition, in fiscal 1997, MEDE AMERICA recorded a
gain of $885,000 from a sale of securities. See Note 12 of Notes to Consolidated
Financial Statements of MEDE AMERICA.

Year Ended June 30, 1997 Compared to Year Ended June 30, 1996

     Revenues.

     Revenues for the fiscal year ended June 30, 1997 were $35.3 million
compared to $31.8 million in fiscal 1996, representing an increase of 11%. The
increase was primarily attributable to revenue from the acquisition of TCS in
February 1997, partially offset by the loss of revenues from operations that
were divested. The increase was also due to the growth of the existing business.

     MEDE AMERICA processed 161 million transactions in the fiscal year ended
June 30, 1997 compared to 129 million transactions processed in fiscal 1996,
representing an increase of 25%. The increase resulted from the addition of new
clients, the growth of business from existing clients and the

                                       238
<PAGE>   249

TCS acquisition. The average price per transaction in fiscal 1997 declined by 4%
from fiscal 1996, primarily as a result of the divested operations having higher
claims pricing.

     Operating Expenses.

     Operations expense was $16.8 million for the fiscal year ended June 30,
1997 compared to $19.2 million in fiscal 1996, representing a decrease of 12%.
As a percentage of revenues, operations expense decreased from 60% in fiscal
1996 to 48% in fiscal 1997. The operations expense improvement was a result of
ongoing cost reduction programs, systems consolidation for recent acquisitions
and the divestitures of non-core or unprofitable operations.

     Sales, marketing and client services expense was $8.8 million for the
fiscal year ended June 30, 1997 compared to $7.1 million in fiscal 1996,
representing an increase of 24%. As a percentage of revenues, sales, marketing
and client service expense increased from 22% in fiscal 1996 to 25% in fiscal
1997. These increases reflect the inclusion of the TCS acquisition in the
results for five months and, to a lesser extent, the addition of client support
personnel and the increase in help desk tracking software expenses.

     Research and development expense was $3.3 million for the fiscal year ended
June 30, 1997 compared to $2.1 million in fiscal 1996, representing an increase
of 54%. As a percentage of revenues, research and development expense increased
from 7% in fiscal 1996 to 9% in fiscal 1997. These increases were due to the
hiring of new employees and other expenses related to the expansion of MEDE
AMERICA's processing capacity and the implementation of new technology
processing platforms throughout its data processing centers.

     General and administrative expense was $5.3 million for the fiscal year
ended June 30, 1997 compared to $6.1 million in fiscal 1996, representing a
decrease of 13%. As a percentage of revenues, general and administrative expense
decreased from 19% in fiscal 1996 to 15% in fiscal 1997. These decreases were
primarily a result of consolidation and integration activities.

     Depreciation and amortization expense was $5.5 million for fiscal year
ended June 30, 1997 compared to $5.2 million in fiscal 1996, representing an
increase of 5%. As a percentage of revenues, depreciation and amortization
expense decreased from 16% in fiscal 1996 to 15% in fiscal 1997.

     Acquisition-related expenses for the fiscal year ended June 30, 1997
included a $1.6 million write-off related to in-process research and development
from the acquisition of TCS (for software that had not achieved technological
feasibility and had no alternative use) and a contingent earnout charge of $2.3
million recorded by us in connection with the EC&F purchase agreement. In
addition, in fiscal 1997, MEDE AMERICA recorded a gain of $885,000 from a sale
of securities. See Note 12 of MEDE AMERICA notes to consolidated financial
statements.

     During the fiscal year ended June 30, 1996, MEDE AMERICA wrote down
approximately $10.0 million of costs relating to client lists and related
allocable goodwill obtained in the acquisition of MEDE OHIO. Such intangible
assets were written down to the net present value of the estimated future cash
flows to be derived from these clients as of June 30, 1996. The write-down was
required due to a loss of approximately 25% of the acquired MEDE OHIO client
base. In addition, a contingent earnout charge of $538,000 was recorded in
connection with the EC&F purchase agreement during the fiscal year ended June
30, 1996.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, MEDE AMERICA has used capital from external sources to
fund its internal growth and operations and to make acquisitions. Prior to its
initial public offering, such capital requirements were provided by (1) MEDE
AMERICA's four principal stockholders, through periodic purchases of its debt
and equity securities and (2) MEDE AMERICA's Credit Facility. Since June 30,
1995 an investment fund affiliated with Welsh, Carson, Anderson and Stowe, or
WCAS, has purchased a senior subordinated note in the principal amount of $25.0
million and 370,993 shares of common stock from MEDE AMERICA for an aggregate
$25.0 million, which was used in connection with the acquisition of Time-

                                       239
<PAGE>   250

Share Computer Systems, Inc., to repay borrowings under the Credit Facility and
for general working capital purposes. In October 1998, the total availability
under the Credit Facility was increased to $36.0 million, and MEDE AMERICA drew
down an additional $13.2 million, of which $11.7 million was used to finance the
HII acquisition.

     On January 26, 1999, MEDE AMERICA entered into a new credit facility with
NationsBank, N.A., as Administrative Agent, and NationsBanc Montgomery
Securities LLC, as Syndication Agent. The credit facility provides for a $25
million revolving credit facility that matures on February 5, 2002. The credit
facility is not guaranteed by any third party, but is secured by substantially
all of MEDE AMERICA's assets including the stock of MEDE AMERICA's subsidiaries.
The credit facility contains various covenants and conditions, including those
relating to Year 2000 compliance, changes in control and management and
restrictions on the payment of dividends on the common stock. The closing of the
credit facility occurred simultaneously with the consummation of the initial
public offering. As of March 31, 1999, MEDE AMERICA had outstanding borrowings
of $6.0 million under the credit facility. Such borrowings bore interest at a
weighted average rate of 7.4% per year as of March 31, 1999.

     On February 5, 1999, MEDE AMERICA consummated an initial public offering of
5,307,710 shares of common stock at a price of $13.00 per share (including
692,310 shares that were subject to the underwriters' overallotment option,
which was exercised in full). The net proceeds to us were approximately $61.9
million (after deducting the underwriting discount and offering expenses payable
by us). The net proceeds to us were used to (1) prepay approximately $25.2
million of outstanding principal and accrued interest on MEDE AMERICA's
outstanding 10% senior subordinated note due February 1, 2002 and (2) repay
approximately $28.3 million of outstanding indebtedness and accrued interest
under MEDE AMERICA's credit facility. MEDE AMERICA used the remaining $8.4
million of net proceeds to pay a portion of outstanding accrued dividends on its
preferred stock, and approximately $301,000 of accrued dividends were converted
into 23,124 shares of common stock. In addition, in connection with the initial
public offering all outstanding shares of preferred stock were converted into
1,845,815 shares of common stock at the initial public offering price of $13.00
per share. In connection with the prepayment of the senior subordinated note and
the establishment of the New Credit Facility, MEDE AMERICA recorded an
extraordinary charge of approximately $1.6 million relating to the write-off of
the remaining discount on the Senior Subordinated Note and deferred financing
costs.

     As of March 31, 1999, MEDE AMERICA had cash and cash equivalents of $4.0
million and net working capital of $9.4 million. Net cash used in operations was
$8.1 million for the nine months ended March 31, 1999. The $8.1 million net cash
used in operations in the nine months ended March 31, 1999 resulted primarily
from increased investments in accounts receivable of $2.0 million, formulary
receivables of $2.6 million (as a result of growth in the pharmacy business),
and other assets of $642,000, as well as a decrease in accounts payable and
accrued expenses of $2.6 million due to the timing of payments, partially offset
by the $5.5 million of income from operations (after adding back non-cash
charges).

     Cash used for investment purposes was $13.6 million in nine months ended
March 31, 1999. Cash used for investment purposes during the nine months ended
March 31, 1999 was primarily used to acquire HII for $11.4 million (net of cash
acquired), and to fund capital expenditures of $1.1 million and additions to
intangible assets of $1.0 million. MEDE AMERICA expect to pay at least $2.0
million per year for the foreseeable future for capital investment to support
growth in transaction processing.

     Cash provided by financing activities was $17.2 million for the nine months
ended March 31, 1999. Cash provided by financing activities during the nine
months ended March 31, 1999 was primarily provided from net proceeds from the
IPO of $61.9 million, which was partially offset by principal repayments of debt
and capital lease obligations and the payment of preferred stock dividends.

     On April 20, 1999, MEDE AMERICA, Healtheon and Merc Acquisition Corp., a
wholly-owned subsidiary of Healtheon entered into the MEDE AMERICA
reorganization agreement, pursuant to which Merc will be merged with and into
MEDE AMERICA, with MEDE AMERICA being the surviving corporation of the
reorganization. Upon consummation of the merger, the separate existence of Merc
will

                                       240
<PAGE>   251

cease, and MEDE AMERICA's existing stockholders will become stockholders of
Healtheon in accordance with the terms of the merger agreement.

     If the MEDE AMERICA reorganization is not consummated and MEDE AMERICA's
independent existence continues, MEDE AMERICA would expect to use the credit
facility to finance its future acquisitions and for general working capital
needs, and subject to satisfaction of the covenants set forth therein, might
finance acquisitions through the issuance of additional equity and debt
securities. MEDE AMERICA believes that existing cash balances and cash generated
by operations in the near term, and the borrowings available under the credit
facility, would be sufficient to finance its operations for at least an
additional 18 months. However, future acquisitions might require funding beyond
its cash resources and currently anticipated capital or operating requirements
could change, with the result that it would be required to raise additional
funds through the public or private sale of additional securities.

YEAR 2000 COMPLIANCE

Assessment

     Since 1996, MEDE AMERICA has specified that all developed software be Year
2000 compliant. In January 1998 MEDE AMERICA performed a product assessment on
all legacy products identifying all those that were not Year 2000 compliant, and
began the process of renovating its existing non-compliant products (usually in
connection with improving product functionality). In August 1998, all Year 2000
remediation programs were centralized under the direction of a Year 2000 Project
Manager. Also in 1998 MEDE AMERICA began tracking Year 2000 expenditures as a
separate category of expenditures. Total Year 2000 expenditures prior to August
1, 1998 amounted to approximately $225,000; expenditures from August 1, 1998
through March 31, 1999 totaled approximately $544,000.

     MEDE AMERICA has completed its assessment of whether it will have to modify
or replace portions of its software and its products, services and internal
systems so that they will function properly with respect to dates in the year
2000 and thereafter. In addition to its general Year 2000 compliance review,
MEDE AMERICA has specifically identified several areas which are not Year 2000
compliant as of November 30, 1998:

     - its PBM system in Ohio;

     - the UNIX operating platform software used in connection with its pharmacy
       practice management system; and

     - the UNIX operating platform software utilized in its pharmacy transaction
       switching. With the exception of the Ohio PBM system, MEDE AMERICA
       believes its internally developed software and systems are Year 2000
       compliant.

     With the exception of the Ohio PBM system, MEDE AMERICA believes its
internally developed software and systems are Year 2000 compliant.

Remediation and Implementation

     MEDE AMERICA has developed a remediation program to correct the Year 2000
problems it has identified. PBM clients who utilize MEDE AMERICA's PBM system in
Ohio are being migrated to the PBM system it acquired from Stockton, which MEDE
AMERICA considers to be Year 2000 compliant. Testing has been completed and
migration of these clients has begun, with 14% of the client base migrated. The
migration process is scheduled for completion in August 1999. For retail
pharmacy practice management clients, MEDE AMERICA's remediation program
consists of providing a Year 2000 compliant version of the UNIX software to
replace the older non-compliant version (which is no longer being supported by
the vendor), as well as software upgrades, with discounted hardware packages to
enable such clients to utilize the Year 2000 compliant system. MEDE AMERICA has
completed upgrades for 130 clients, and has scheduled upgrades for an additional
40 clients, with 55 clients still in the sales process. A version of the UNIX
operating platform software used in pharmacy transaction switching,

                                       241
<PAGE>   252

which the manufacturer represents to be Year 2000 compliant, was released in
December 1998. Testing of that operating platform software on MEDE AMERICA's
hardware, with its pharmacy transaction switching software, has begun. The
software performed correctly on test equipment, and is currently in test on
production hardware. Testing is scheduled for completion in June 1999.

     During its assessment phase, MEDE AMERICA identified potentially Year 2000
non-compliant "non-information technology" systems (such as embedded
microcontrollers). Accordingly, it is replacing its older (and potentially
non-compliant) computer and telecommunications hardware with hardware that is
Year 2000 compliant. These expenditures are being made in the general course of
MEDE AMERICA's renovation and modernization program, and as such are accounted
for as ordinary capital expenditures instead of Year 2000 expenses.

     In October 1998, MEDE AMERICA acquired HII. HII's EDI products and services
fall into three categories: (1) physician claims processing (small-and
large-group), (2) hospital claims processing and (3) claims data transmission
(extraction and transmission of claim data to a third party data analyst). Based
on its review at the time of the acquisition, MEDE AMERICA determined that none
of HII's products is Year 2000 compliant. MEDE AMERICA has completed the
programming necessary to modify HII's common carrier and Internet-based claims
processing system for small physician groups to make the products Year 2000
compliant. Clients are being selected for beta-testing. It also intends to
modify HII's payer data transmission products to make such products Year 2000
compliant. These modifications are scheduled to be completed in July 1999. MEDE
AMERICA is migrating HII's claims processing for hospitals and large physician
groups to its MEDE Claim product. Currently, 12 clients have installed the MEDE
Claim product, 25 more are under contract, 17 have declined to migrate to the
system, and the remainder have either committed verbally to upgrade, or are in
various stages of contract negotiation. MEDE AMERICA can, if necessary, process
claims for hospitals and large physician groups through its common carrier and
Internet-based claims processing system.

     Some or all of MEDE AMERICA's revenues from each of the three areas in
which Year 2000 problems have been identified, as well as those of HII's
clients, are subject to the risk of Year 2000 noncompliance. The total revenue
from MEDE AMERICA's PBM services clients was $6,491,000 in fiscal 1998. The
total revenue from Pharmacy retail system sales was $511,000 in fiscal 1998. The
total revenue derived from Pharmacy switching was $8,183,000 in fiscal 1998. The
total claims and related revenue derived from HII was $4,950,000 for the twelve
months ended June 30, 1998.

     Excluding anticipated expenditures associated with ordinary product
development, MEDE AMERICA has budgeted approximately $1,210,000 through December
1999 for Year 2000 compliance costs, of which approximately $769,000 had been
expended through March 31, 1999. MEDE AMERICA believes that this amount will be
sufficient to execute its plan and cover contingency plan costs. MEDE AMERICA
believes that it has sufficient resources to implement its plan. However, there
can be no assurance that expenditures required to achieve compliance with Year
2000 requirements will not exceed the budgeted amounts.

     MEDE AMERICA's client base consists of over 65,000 healthcare providers and
over 1,000 payers. While it has not attempted to assess the readiness of each of
these entities, MEDE AMERICA has begun to work with major customers and
suppliers to insure that Year 2000 compliance issues will not interrupt the
normal activities supported by these relationships. Implementation of Year 2000
compliant software is product-and platform-specific. If the software resides on
the host system, all clients will automatically access the new software.
Similarly, products that can receive updates remotely will be updated via remote
distribution. The existing telephone number for HII's bulletin board program can
be automatically redirected to connect to a product of ours that is Year 2000
compliant. A small minority of MEDE AMERICA's clients (mostly retail pharmacy
clients) will require on-site installation (in most cases, this installation
will also provide the clients with the capability to receive future enhancements
that will not otherwise be available).

     MEDE AMERICA's Medicare/Medicaid payers are subject to a Year 2000
compliance program undertaken by the Health Care Financing Administration. Under
the HCFA plan, all mission critical systems have been identified, and an
Independent Verification and Validation consultant has been retained

                                       242
<PAGE>   253

to perform inspections and testing of all public payers. This plan includes both
random and announced system and site testing.

Contingencies

     MEDE AMERICA believes that the most likely worst case Year 2000 scenario
would include the following:

     - one or more parts of MEDE AMERICA's software and operating systems would
       operate incorrectly;

     - one or more of MEDE AMERICA's payers would be unable to receive
       transactions; and

     - one or more of MEDE AMERICA's providers/clients would not have completed
       internal Year 2000 conversions.

     It is possible that failures of the type described in clause (1) of the
preceding sentence could cause MEDE AMERICA's clients to either terminate their
contracts with us and/or sue us for damages. Also, if MEDE AMERICA fails to
achieve Year 2000 compliance by September 30, 1999, such failure could
constitute a default under the New Credit Facility, which could in turn have a
material adverse effect on MEDE AMERICA's business, financial condition and
results of operations. MEDE AMERICA has completed the assessment of its critical
hardware and software and believes that the assessment has revealed all
significant Year 2000 problems, that such problems will be capable of
remediation, and that its software and hardware will perform substantially as
planned when Year 2000 processing begins. Although it may experience Year 2000
problems, based on its assessment and remediation program to date, MEDE AMERICA
believes that Year 2000 compliance issues will not have a material adverse
effect on its business, financial condition or prospects and will not,
therefore, result in a default under the Year 2000 compliance covenant in the
New Credit Facility. However, due to the uncertainties that are inherent in
addressing the Year 2000 problem, MEDE AMERICA may experience unforeseen Year
2000 problems, which problems could have a material adverse effect on MEDE
AMERICA's business, financial condition and results of operations.

     As contingency planning, MEDE AMERICA has three available options should
certain functions not operate properly on January 1, 2000.

     - MEDE AMERICA has developed its internal systems in such a manner as to
       allow such systems to accept non-Year 2000 compliant data, and convert
       such data based on defaults and algorithms developed in conjunction with
       the providers to Year 2000 compatible formats. This methodology is
       applicable for claims, eligibility and enrollment transactions.

     - For payers, in the event a payer is unable to accept EDI claims, MEDE
       AMERICA currently has the capability, internally and, if necessary with
       support from an outside vendor, to print paper claims forms from supplied
       provider data and to send those claims in paper form to non-Year 2000
       compliant payers.

     - For medical claims, a bulletin board system acquired in the HII
       transaction could be utilized by clients, with minimal programming set
       up, as a means of transmitting claims to us via common carriers and the
       Internet.

IMPACT OF INFLATION

     Inflation has not had a material impact on MEDE AMERICA's historical
operations or financial condition.

RECENT ACCOUNTING PRONOUNCEMENTS

     Recent pronouncements of the Financial Accounting Standards Board, which
are not required to be adopted at this date, include SFAS No. 131, "Disclosures
about Segments of an Enterprise and Related

                                       243
<PAGE>   254

Information", and SFAS No. 133 "Accounting for Derivative Instruments and
Hedging Activities." These pronouncements are not expected to have a material
impact on MEDE AMERICA's financial statements.

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 981, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use." This statement is not required to be
adopted at this date. MEDE AMERICA is currently evaluating the impact of this
statement on its financial statements.

NET OPERATING LOSSES

     As of June 30, 1998, MEDE AMERICA had net operating loss carryforwards for
federal income tax purposes of approximately $36.4 million. Such loss
carryforwards expire in the fiscal years 2005 through 2013. Because of certain
changes in ownership, as defined in the Internal Revenue Code, which occurred
during 1996 and 1995, certain of these net operating loss carryforwards are
subject to annual limitations. See Note 7 of MEDE AMERICA notes to consolidated
financial statements.

                    ADDITIONAL MATTERS BEING SUBMITTED TO A
                      VOTE OF ONLY HEALTHEON STOCKHOLDERS

                    APPROVAL OF AMENDMENT TO 1996 STOCK PLAN

     Stockholders are being asked to approve an amendment to the 1996 Stock Plan
to provide for an increase in the number of shares of common stock reserved for
issuance under the plan by 10,000,000 shares. The board believes that adding
shares to the plan is in the best interests of Healtheon because it will permit
Healtheon to attract and retain employees by providing them with appropriate
equity incentives. The plan plays an important role in Healtheon's efforts to
attract and retain employees of outstanding ability.

     Set forth below is a summary of the principal features of the incentive
plan. Healtheon will provide, without charge, to each person to whom a proxy
statement is delivered, upon request of such person and by first class mail
within three business days of receipt of such request, a copy of the incentive
plan. Any such request should be directed as follows: Secretary, Healtheon
Corporation, 4600 Patrick Henry Drive, Santa Clara, California 95054; telephone
number (408) 876-5000.

SUMMARY OF THE 1996 PLAN

     General. The purpose of the 1996 Plan, or the "Plan," is to attract and
retain the best available personnel for positions of substantial responsibility
with Healtheon, to provide additional incentive to the employees, directors and
consultants of Healtheon and to promote the success of Healtheon's business.
Options and stock purchase rights may be granted under the Plan. Options granted
under the Plan may be either "incentive stock options," as defined in Section
422 of the tax code, or nonstatutory stock options.

     Administration. The Plan may generally be administered by the board or a
committee appointed by the Board, as applicable, the "Administrator".

     Eligibility; Limitations. Nonstatutory stock options and stock purchase
rights may be granted under the Plan to employees, directors and consultants of
Healtheon and any parent or subsidiary of Healtheon. Incentive stock options may
be granted only to employees. The Administrator, in its discretion, selects the
employees, directors and consultants to whom options and stock purchase rights
may be granted, the time or times at which such options and stock purchase
rights shall be granted, and the number of shares subject to each such grant.

     Section 162(m) of the tax code places limits on the deductibility for
federal income tax purposes of compensation paid to certain executive officers
of Healtheon. In order to preserve Healtheon's ability to deduct the
compensation income associated with options and stock purchase rights granted to
such persons, the Plan provides that no employee, director or consultant may be
granted, in any fiscal year of Healtheon, options and stock purchase rights to
purchase more than 500,000 shares of common stock. Notwithstanding this limit,
however, in connection with such individual's initial employment with the he or
she may be granted options or stock purchase rights to purchase up to an
additional 500,000 shares of common stock.

                                       247
<PAGE>   258

     Terms and Conditions of Options. Each option is evidenced by a stock option
agreement between Healtheon and the optionee, and is subject to the following
additional terms and conditions:

          (a) Exercise Price. The Administrator determines the exercise price of
     options at the time the options are granted. The exercise price of an
     incentive stock option may not be less than 100% of the fair market value
     of the common stock on the date such option is granted; provided, however,
     the exercise price of an incentive stock option granted to a 10%
     stockholder may not be less than 110% of the fair market value of the
     common stock on the date such option is granted. The fair market value of
     the common stock is generally determined with reference to the closing sale
     price for the common stock on the last market trading day prior to the date
     the option is granted.

          (b) Exercise of Option; Form of Consideration. The Administrator
     determines when options become exercisable, and may in its discretion,
     accelerate the vesting of any outstanding option. Stock options granted
     under the Plan generally vest and become exerciseable over four years. The
     means of payment for shares issued upon exercise of an option is specified
     in each option agreement. The Plan permits payment to be made by cash,
     check, promissory note, other shares of common stock of Healtheon, with
     some restrictions, cashless exercises, a reduction in the amount of any
     company liability to the optionee, any other form of consideration
     permitted by applicable law, or any combination thereof.

          (c) Term of Option. The term of an incentive stock option may be no
     more than ten (10) years from the date of grant; provided that in the case
     of an incentive stock option granted to a 10% stockholder, the term of the
     option may be no more than five (5) years from the date of grant. No option
     may be exercised after the expiration of its term.

          (d) Termination of Employment. If an optionee's employment or
     consulting relationship terminates for any reason, other than death or
     disability, then all options held by the optionee under the Plan expire on
     the earlier of (1) the date set forth in his or her notice of grant or (2)
     the expiration date of such option. To the extent the option is exercisable
     at the time of such termination, the optionee may exercise all or part of
     his or her option at any time before termination.

          (e) Death or Disability. If an optionee's employment or consulting
     relationship terminates as a result of death or disability, then all
     options held by such optionee under the Plan expire on the earlier of (1)
     12 months from the date of such termination or (2) the expiration date of
     such option. The optionee, or the optionee's estate or the person who
     acquires the right to exercise the option by bequest or inheritance, may
     exercise all or part of the option at any time before such expiration to
     the extent that the option was exercisable at the time of such termination.

          (g) Nontransferability of Options: Options granted under the Plan are
     not transferable other than by will or the laws of descent and
     distribution, and may be exercised during the optionee's lifetime only by
     the optionee, unless otherwise determined by the Administrator.

          (h) Other Provisions: The stock option agreement may contain other
     terms, provisions and conditions not inconsistent with the Plan as may be
     determined by the Administrator.

     Stock Purchase Rights. In the case of SPRs, unless the Administrator
determines otherwise, the restricted stock purchase agreement shall grant
Healtheon a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser's employment with Healtheon for any reason. The
purchase price for shares repurchased pursuant to the restricted stock purchase
agreement shall be the original price paid by the purchaser and may be paid by
cancellation of any indebtedness of the purchaser to Healtheon. The repurchase
option shall lapse at a rate determined by the Administrator.

     Adjustments Upon Changes in Capitalization. In the event that the stock of
Healtheon changes by reason of any stock split, reverse stock split, stock
dividend, combination, reclassification or other similar change in the capital
structure of Healtheon effected without the receipt of consideration,
appropriate adjustments shall be made in the number and class of shares of stock
subject to the Plan, the number and

                                       248
<PAGE>   259

class of shares of stock subject to any option or stock purchase right
outstanding under the Plan, and the exercise price of any such outstanding
option or stock purchase right.

     In the event of a liquidation or dissolution, the Administrator shall
notify each optionee at least fifteen days prior to such action, and any
unexercised options or stock purchase rights will terminate immediately prior
thereto.

     In connection with any merger, consolidation, acquisition of assets or like
occurrence involving Healtheon, each outstanding option or stock purchase right
may be assumed or an equivalent option or right substituted by the successor
corporation. If the successor corporation refuses to assume the options and
stock purchase rights or to substitute substantially equivalent options and
stock purchase rights, the optionee shall have the right to exercise the option
or stock purchase right as to all of the optioned stock, including shares not
otherwise exercisable.

     Amendment and Termination of the Plan. The Board may amend, alter, suspend
or terminate the Plan, or any part thereof, at any time and for any reason.
However, Healtheon shall obtain shareholder approval for any amendment to the
Plan to the extent necessary to comply with applicable laws. No such action by
the board of directors or stockholders may alter or impair any option or stock
purchase right previously granted under the Plan without the written consent of
the optionee. Unless terminated earlier, the Plan shall terminate ten years from
the date of its approval by the stockholders or the board of directors of
Healtheon, whichever is earlier.

FEDERAL INCOME TAX CONSEQUENCES

     Incentive Stock Options. An optionee who is granted an incentive stock
option does not recognize taxable income at the time the option is granted or
upon its exercise, although the exercise may subject the optionee to the
alternative minimum tax. Upon a disposition of the shares more than two years
after grant of the option and one year after exercise of the option, any gain or
loss is treated as long-term capital gain or loss. If these holding periods are
not satisfied, the optionee recognizes ordinary income at the time of
disposition equal to the difference between the exercise price and the lower of
(1) the fair market value of the shares at the date of the option exercise or
(2) the sale price of the shares. Any gain or loss recognized on such a
premature disposition of the shares in excess of the amount treated as ordinary
income is treated as long-term or short-term capital gain or loss, depending on
the holding period. A different rule for measuring ordinary income upon such a
premature disposition may apply if the optionee is also an officer, director, or
10% shareholder of Healtheon. Net capital gains on shares held for more than 12
months are taxed at a maximum rate of 20%. Capital losses are allowed in full
against capital gains and up to $3,000 against other income. Healtheon is
generally entitled to a deduction in the same amount as the ordinary income
recognized by the optionee.

     Nonstatutory Stock Options. An optionee does not recognize any taxable
income at the time he or she is granted a nonstatutory stock option. Upon
exercise, the optionee recognizes taxable income generally measured by the
excess of the then fair market value of the shares over the exercise price. Any
taxable income recognized in connection with an option exercise by an employee
of Healtheon is subject to tax withholding by Healtheon. Healtheon is generally
entitled to a deduction in the same amount as the ordinary income recognized by
the optionee. Upon a disposition of such shares by the optionee, any difference
between the sale price and the optionee's exercise price, to the extent not
recognized as taxable income as provided above, is treated as long-term or
short-term capital gain or loss, depending on the holding period. Net capital
gains on shares held for more than 12 months are taxed at a maximum rate of 20%.
Capital losses are allowed in full against capital gains and up to $3,000
against other income.

     Stock Purchase Rights. Stock purchase rights will generally be taxed in the
same manner as nonstatutory stock options. However, restricted stock is
generally purchased upon the exercise of a stock purchase right. At the time of
purchase, restricted stock is subject to a "substantial risk of forfeiture"
within the meaning of Section 83 of the Code. As a result, the purchaser will
not recognize ordinary income at the time of purchase. Instead, the purchaser
will recognize ordinary income on the dates when the stock ceases to be subject
to a substantial risk of forfeiture. The stock will generally cease to be

                                       249
<PAGE>   260

subject to a substantial risk of forfeiture when it is no longer subject to
Healtheon's right to repurchase the stock upon the purchaser's termination of
employment with Healtheon. At such times, the purchaser will recognize ordinary
income measured as the difference between the purchase price and the fair market
value of the stock on the date the stock is no longer subject to a substantial
risk of forfeiture.

     The purchaser may accelerate to the date of purchase his or her recognition
of ordinary income, if any, and the beginning of any capital gain holding period
by timely filing an election pursuant to Section 83(b) of the Code. In such
event, the ordinary income recognized, if any, is measured as the difference
between the purchase price and the fair market value of the stock on the date of
purchase, and the capital gain holding period commences on such date. The
ordinary income recognized by a purchaser who is an employee will be subject to
tax withholding by Healtheon. Different rules may apply if the purchaser is also
an officer, director, or 10% shareholder of Healtheon.

     THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME TAXATION
UPON OPTIONEES, HOLDERS OF STOCK PURCHASE RIGHTS, AND HEALTHEON WITH RESPECT TO
THE GRANT AND EXERCISE OF OPTIONS AND STOCK PURCHASE RIGHTS UNDER THE PLAN. IT
DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF
THE EMPLOYEE'S OR CONSULTANT'S DEATH OR THE PROVISIONS OF THE INCOME TAX LAWS OF
ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE EMPLOYEE OR CONSULTANT
MAY RESIDE.

     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE
AMENDMENT TO THE 1996 STOCK PLAN.

          COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT

     Section 16(a) of the Securities Exchange Act requires Healtheon's directors
and executive officers, and persons who own more than 10% of Healtheon's common
stock, to file with the Securities and Exchange Commission initial reports of
ownership on a Form 3 and reports of changes in ownership of common stock and
other equity securities of Healtheon on a Form 4 or Form 5. Officers, directors
and 10% stockholders are required by SEC regulations to furnish Healtheon with
copies of all Section 16(a) forms they file.

     To Healtheon's knowledge, based solely on review of the copies of the
reports furnished to Healtheon and written representations from the executive
officers and directors, Healtheon believes that all Section 16(a) filing
requirements applicable to its officers, directors, and 10% stockholders were
met during 1998, except with respect to a late Form 4 filing by Thomas Jermoluk,
a director of Healtheon.

that uncertainty.

amounts included for the period for the period from May 24, 1995 (date of
incorporation) to December 31, 1996. The report of PricewaterhouseCoopers LLP

losses and negative cash flows from operations which raise substantial doubt
about its ability to continue as a going concern.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Healtheon Corporation

     We have audited the accompanying consolidated balance sheets of Healtheon
Corporation as of December 31, 1998 and 1997, and the related consolidated
statements of operations, convertible redeemable preferred stock and
stockholders' equity (net capital deficiency), and cash flows for each of the
three years in the period ended December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits. In May
1998, the Company acquired ActaMed Corporation in a transaction that was
accounted for as a pooling of interests. We did not audit the financial
statements of ActaMed Corporation for the year ended December 31, 1996, which
statements reflect revenues and a net loss constituting approximately 89% and
54%, respectively, of the related consolidated financial statement totals for
the year ended December 31, 1996. Those statements were audited by other
auditors whose report has been furnished to us, and our opinion, insofar as it
relates to data included for ActaMed Corporation, is based solely on the report
of the other auditors.

     We conducted our audits in accordance with generally accepted accounting
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of the other auditors provide a
reasonable basis for our opinion.

     In our opinion, based on our audits and the report of the other auditors,
the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of Healtheon Corporation at
December 31, 1998 and 1997, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1998, in conformity with generally accepted accounting principles.

                          INDEPENDENT AUDITOR'S REPORT

Board of Directors of ActaMed Corporation

     We have audited the consolidated statements of operations, convertible
redeemable preferred stock and stockholders' equity (net capital deficiency),
and cash flows of ActaMed Corporation and subsidiary (the "Company") for the
year ended December 31, 1996 (the consolidated financial statements for 1996 are
not separately presented herein). These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provide a reasonable basis for our opinion.

     In our opinion, such consolidated statements of operations, convertible
redeemable preferred stock and stockholders' equity (net capital deficiency),
and cash flows present fairly, in all material respects, the results of the
Company's operations and its cash flows for the year ended December 31, 1996 in
conformity with generally accepted accounting principles.

                             HEALTHEON CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
        (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1999 AND 1998 IS UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

     In May 1998, Healtheon Corporation acquired ActaMed Corporation in a merger
transaction accounted for as a pooling of interests (see Note 2). ActaMed was
incorporated in 1992 and Healtheon was incorporated on December 26, 1995. All
financial information has been restated to reflect the combined operations of
Healtheon and ActaMed.

Nature of Operations

     Healtheon is pioneering the use of the Internet to simplify workflows,
decrease costs and improve the quality of patient care throughout the healthcare
industry. We have designed and developed an Internet-based information and
transaction platform, which we call the Healtheon Platform, that allows us to
create Virtual Healthcare Networks, or VHNs, that facilitate and streamline
interactions among the myriad participants in the healthcare industry. Our VHN
solution includes a suite of services delivered through applications operating
on our Internet-based platform. Our solution enables the secure exchange of
information among disparate healthcare information systems and supports a broad
range of healthcare transactions, including enrollment, eligibility
determination, referrals and authorization, laboratory and diagnostic test
ordering, clinical data retrieval and claims processing. We provide our own
applications on the Healtheon Platform and also enable third-party applications
to operate on the platform. In addition to VHNs, Healtheon provides consulting,
implementation and network management services to enable our customers to take
advantage of the capabilities of the Healtheon Platform.

Principles of Consolidation

     The consolidated financial statements include the accounts of Healtheon and
its wholly owned subsidiaries. All significant inter-company balances and
transactions have been eliminated.

Accounting Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements. Actual
results could differ materially from these estimates.

Cash, Cash Equivalents and Short-Term Investments

     All highly liquid investments with an original maturity from date of
purchase of three months or less are considered to be cash equivalents.
Healtheon's cash, cash equivalents and short-term investments are invested in
various investment-grade commercial paper, money market accounts and
certificates of deposit. All of our short-term investments mature within nine
months. The fair value of our cash equivalents and short-term investments is as
follows (in thousands):

</TABLE>

     Net unrealized gains (losses) were immaterial at March 31, 1999 and
December 31, 1998 and 1997.

     Management determines the appropriate classification of debt and equity
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. Marketable debt and equity securities are classified as
available-for-sale, and are carried at their fair value, with the unrealized
gains and losses, when material, reported net-of-tax in a separate component of
stockholders' equity. Realized gains and losses and declines in value judged to
be other-than-temporary on available-for-sale securities are included in
interest income. The cost of securities sold is based on specific
identification. Interest and dividends on securities classified as
available-for-sale are included in interest income.

     Additionally, at December 31, 1998 and 1997, we had restricted cash of
$867,000, related to a letter of credit invested in a certificate of deposit at
a financial institution as a security deposit for its office facilities (see
Note 6). This amount is included in other assets in the accompanying
consolidated balance sheets at December 31, 1998 and 1997. We had no restricted
cash at March 31, 1999.

Property and Equipment

     Property and equipment are stated at cost, net of accumulated amortization
and depreciation. Depreciation is computed using the straight-line method over
the estimated useful life of the related asset, generally three to seven years.
Leasehold improvements and equipment acquired under capital leases are amortized
over the shorter of the lease term or the estimated useful life of the related
asset.

Intangible Assets

     Intangible assets related to software technology rights, services
agreements and goodwill are amortized on a straight-line basis over three years.
Intangible assets related to assembled workforce are amortized on a
straight-line basis over two years.

                             HEALTHEON CORPORATION

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
        (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1999 AND 1998 IS UNAUDITED)

Software Development Costs

     Software development costs are incurred in the development or enhancement
of software utilized in providing Healtheon's services. Software development
costs incurred after the establishment of technological feasibility for each
product or process are capitalized and capitalization ceases when the product or
process is available for general release to customers or is put into service.
Capitalized internally developed software costs were approximately $291,000 in
1997. There were no internally developed software costs capitalized in 1998 or
during the three months ended March 31, 1999. Capitalized internally developed
software costs are amortized based on the greater of the amount determined using
the straight line method over the estimated useful economic life of the software
or the ratio of remaining unamortized costs to current and expected future
revenue from the software. Amortization expense related to our capitalized
internally developed software costs included in cost of operations was
approximately $782,000, $376,000 and $134,000 for the years ended December 31,
1998, 1997 and 1996. Amortization expense was approximately $108,000 for the
three months ended March 31, 1998.

Long-Lived Assets

     Healtheon continually monitors events and changes in circumstances that
could indicate carrying amounts of long-lived assets, including intangible
assets, may not be recoverable. When such events or changes in circumstances are
present, we assess the recoverability of long-lived assets by determining
whether the carrying value of such assets will be recovered through undiscounted
expected future cash flows. In June 1998, we evaluated the carrying value of the
capitalized internally developed software in light of the changes in operations
resulting from the acquisition of ActaMed by Healtheon. We determined that we
expected no future cash flows to be generated by this software and, accordingly,
wrote off the remaining unamortized balance of $603,000 related to capitalized
internally developed software. This amount is included in the $782,000
amortization expense in 1998 noted above. No impairment losses were recorded in
1997 and 1996.

Revenue Recognition

     Healtheon earns revenue from services and services to related parties, both
of which include providing access to our network-based services and performing
development and consulting services, and from licensing software. Services
revenue also includes revenue from the management and operation of customers' IT
infrastructure. We earn network-based services revenue from fixed fee
subscription arrangements, which is recognized ratably over the term of the
applicable agreement, and from arrangements that are priced on a per-transaction
or per-user basis, which is recognized as the services are performed. Revenue
from development projects is recognized on a percentage-of-completion basis or
as such services are performed, depending on the terms of the contract. Revenue
from consulting services and revenue from the management and operation of
customers' IT infrastructure is recognized as the services are performed. Cash
received in excess of revenue recognized relating to such services has been
recorded as deferred revenue in the accompanying consolidated balance sheets.
Revenue from services to related parties consists of services revenue
attributable to UnitedHealth Group and SmithKline Labs. To date, we have derived
no significant revenue from brokers, value-added resellers or systems
integrators.

     During 1997, we entered into agreements with two customers to manage and
operate their current and expanding information technology, or IT, operations,
to develop a suite of specific Internet-based commercial software applications
and to assist these customers in migrating from their current IT operating
environment to these new applications. We utilize our own personnel, certain
outside contractors and certain personnel and facilities of the customers that
are leased under contract terms to us for these

as part of the total costs of the IT and development services that we billed to
the customers. In the three months ended March 31, 1999 and 1998, we recognized
revenue of approximately $4,927,000 and $3,800,000 for the IT services and
approximately $549,000 and $777,000 for the development services. In fiscal
1998, we recognized revenue of approximately $15,061,000 for the IT services and
approximately $6,471,000 for the development services. In fiscal 1997, we
recognized revenue of approximately $2,100,000 for the IT services and
approximately $200,000 for the development services. Revenue recognized for IT
services included $3,466,000 in the three months ended March 31, 1999,
$3,450,000 in the three months ended March 31, 1998, $11,792,000 in fiscal 1998
and $1,909,000 in fiscal 1997 related to leased personnel and facilities. These
amounts were also included in cost of operations for the respective periods.

     We recognize revenue from license fees when a noncancellable license
agreement has been signed with a customer, the software product covered by the
license agreement has been delivered, there are no uncertainties surrounding
product acceptance, there are no significant future performance obligations, the
license fees are fixed and determinable and collection of the license fees is
considered probable. Our products do not require significant customization.

     In October 1997, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 97-2, "Software Revenue Recognition."
SOP 97-2 was effective January 1, 1998 and generally requires revenue earned on
software arrangements involving multiple elements such as software products,
upgrades, enhancements, post-contract customer support, installation and
training to be allocated to each element based on the relative fair values of
the elements. There was no material change to our accounting for revenue as a
result of the adoption of SOP 97-2.

     ActaMed entered into a national marketing and licensing agreement, or the
Agreement, with International Business Machines Corporation in 1995 that granted
IBM a nonexclusive, nontransferable right to market ActaMed's software and
services for a total of $6,300,000. Under the Agreement, we recognized software
license revenue of approximately $1,200,000 in 1997 and approximately $3,400,000
in 1996, upon delivery of the software. All revenue under the Agreement had been
recognized by the end of 1997.

     In December 1996, we entered into a new agreement, or the License, to
license our newly granted patent to IBM. As part of the License, IBM agreed to
pay ActaMed $4,800,000 over a four-year period. Additionally, in conjunction
with the License, we issued IBM a five-year warrant to purchase 282,522 shares
of our common stock at a price of $7.97 per share. Because of the extended
payment terms and ActaMed's contentious relationship with IBM, we concluded that
the license fee was not assured of collection and, accordingly, we are
recognizing this revenue as the proceeds are collected. We recognized revenue
from the License of $195,000 in each of the three months ended March 31, 1999
and 1998, $780,000 in fiscal 1998, $780,000 in fiscal 1997 and $995,000 in
fiscal 1996. Accounts receivable included $19,000 at March 31, 1999, $815,000 at
December 31, 1998 and $738,000 at December 31, 1997 due from IBM. Other assets
included $835,000 at March 31, 1999, $900,000 at December 31, 1998 and
$1,715,000 at December 31, 1997 due from IBM. Deferred revenue included
$1,366,000 at March 31, 1999, $1,561,000 at December 31, 1998 and $2,341,000 at
December 31, 1997 related to the License.

Fair Value of Financial Instruments

     The fair value for marketable debt securities is based on quoted market
prices. The carrying value of these securities approximates their fair value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
        (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1999 AND 1998 IS UNAUDITED)

     The fair value of notes is estimated by discounting the future cash flows
using the current interest rates at which similar loans would be made to
borrowers with similar credit ratings and for the same remaining maturities. The
carrying value of the note receivable from an officer approximated its fair
value.

     The fair value of short-term and long-term capital lease obligations is
estimated based on current interest rates available to Healtheon for debt
instruments with similar terms, degrees of risk and remaining maturities. The
carrying values of these obligations approximate their respective fair values.

Concentration of Credit Risk

     Healtheon currently derives a substantial portion of its consolidated
revenue from a few large customers, two of which are related parties. Four
customers represented 30%, 12%, 11% and 10% of the total balance of trade
accounts receivable and amounts due from related parties at December 31, 1998
and two customers represented 35% and 17% of the total balance of trade accounts
receivable and amounts due from related parties at December 31, 1997. We believe
that the concentration of credit risk in our trade receivables, with respect to
our limited customer base, is substantially mitigated by our credit evaluation
process. We do not require collateral. To date, our bad debt write-offs have not
been significant. We added approximately $103,000 in fiscal 1998, $35,000 in
fiscal 1997 and $41,000 in fiscal 1996 to our bad debt reserves. Total
write-offs of uncollectible amounts were $22,000 in fiscal 1998, $5,000 in
fiscal 1997 and zero in 1996.

Accounting for Stock-Based Compensation

     Healtheon grants stock options for a fixed number of shares to employees
with an exercise price equal to the fair market value of the shares at the date
of grant. As permitted under Statement of Financial Accounting Standards (SFAS)
No. 123, "Accounting for Stock-Based Compensation," we account for stock option
grants to employees and directors in accordance with APB Opinion No. 25,
"Accounting for Stock Issued to Employees."

Net Loss Per Common Share

     Basic net loss per common share and diluted net loss per common share are
presented in conformity with SFAS No. 128, "Earnings Per Share," for all periods
presented. In accordance with the Securities and Exchange Commission Staff
Accounting Bulletin No. 98, common stock and convertible preferred stock issued
or granted for nominal consideration prior to the effective date of our initial
public offering must be included in the calculation of basic and diluted net
loss per common share as if they had been outstanding for all periods presented.
We have had no issuances or grants for nominal consideration.

     In accordance with SFAS No. 128, basic net loss per common share has been
computed using the weighted-average number of shares of common stock outstanding
during the period, less shares subject to repurchase. On May 19, 1998, in
connection with Healtheon's acquisition of ActaMed, all outstanding shares of
Healtheon's convertible preferred stock and ActaMed's convertible redeemable
preferred stock were converted into an aggregate of 39,272,329 shares of common
stock.

     We have excluded all convertible redeemable preferred stock, convertible
preferred stock, warrants, outstanding stock options and shares subject to
repurchase by Healtheon from the calculation of diluted loss per common share
because all such securities are anti-dilutive for all periods presented. The
total number of shares excluded from the calculation of diluted loss per share
was 18,208,030 in the three months ended March 31, 1999, 52,570,914 in the three

information on these securities.

Comprehensive Loss

     Healtheon has no material components of other comprehensive loss and
accordingly the comprehensive loss is the same as net loss for all periods
presented.

Reclassifications

     Certain reclassifications have been made to the financial statements to

Unaudited Financial Statements

     The accompanying unaudited financial statements as of March 31, 1999 and

Recent Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." We are
required to adopt SFAS No. 133 for the year ending December 31, 2000. SFAS No.
133 establishes methods of accounting for derivative financial instruments and
hedging activities related to those instruments as well as other hedging
activities. Because we currently hold no derivative financial instruments and do
not currently engage in hedging

activities, adoption of SFAS No. 133 is expected to have no material impact on
our financial condition or results of operations.

     In March 1998, the AICPA issued SOP 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." SOP 98-1 requires
that entities capitalize certain costs related to internal use software once
certain criteria have been met. We are required to implement SOP 98-1 for the
year ending December 31, 1999. Adoption of SOP 98-1 is expected to have no
material impact on our financial condition or results of operations.

     In December 1998, the AICPA issued SOP. 98-9, "Modification of SOP 97-2,
Software Revenue Recognition, with Respect to Certain Transactions." SOP 98-9
requires recognition of revenue using the "residual method" in a
multiple-element software arrangement when fair value does not exist for one or
more of the delivered elements in the arrangement. Under the "residual method,"
the total fair value of the undelivered elements is deferred and recognized in
accordance with SOP 97-2. We are required to implement SOP 98-9 for the year
ending December 31, 2000. SOP 98-9 also extends the deferral of the application
of SOP 97-2 to certain other multiple-element software arrangements through
Healtheon's year ending December 31, 1999. Adoption of SOP 98-9 is expected to
have no material impact on our financial condition or results of operations.

2. BUSINESS COMBINATIONS

Acquisition of EDI Services, Inc.

     Effective March 31, 1996, ActaMed acquired EDI Services Inc., or EDI, a
wholly-owned subsidiary of UnitedHealth Group, in a transaction through which
EDI became a wholly-owned subsidiary of ActaMed. ActaMed issued 6,488,276 shares
of Series C convertible redeemable preferred stock with a fair value of
$21,000,000 and incurred acquisition-related costs of approximately $316,000 in
connection with the acquisition. EDI is a provider of electronic data
interchange services to health care providers and has marketed its health care
network product, ProviderLink, to providers of UnitedHealth Group's local health
plans since 1992.

     In connection with the acquisition, UnitedHealth Group and ActaMed entered
into a five-year Services and License Agreement under which we earn transaction
fee revenue by providing certain health care information services to
UnitedHealth Group and its provider network and ProviderLink subscribers.

     The acquisition was accounted for as a purchase. Accordingly, the
operations of EDI were included in our consolidated statements of operations
after March 31, 1996. Assets and liabilities acquired in connection with this
acquisition were recorded at their estimated fair market values. Approximately
$359,000 of the purchase price was allocated to certain equipment and the
remainder of the purchase price was allocated to intangible assets, consisting
principally of software technology rights, the Services and License Agreement,
trademarks and goodwill.

     Subsequent to the issuance of the financial statements for 1997 and 1996,
ActaMed changed the allocation of the purchase price associated with the
acquisition of the EDI technology to decrease the amount previously expensed as
in process research and development costs and increase the amount capitalized as
software technology rights. The financial statements for ActaMed for the year
ended December 31, 1996, have been reissued to reflect this restatement.

Acquisition of ActaMed Corporation

     On May 19, 1998, Healtheon completed its acquisition of ActaMed, a Georgia
corporation that develops and markets an integrated health care network, in a
transaction that has been accounted for as a pooling of interests. Accordingly,
the financial information presented reflects the combined financial position and
operations of Healtheon and ActaMed for all dates and periods presented.
Healtheon issued 23,271,355 shares of its common stock in exchange for all of
the outstanding shares of common and convertible redeemable preferred stock of
ActaMed. Healtheon also assumed all outstanding stock options and warrants to
acquire 3,383,011 shares of ActaMed capital stock, after giving effect to the
exchange ratio.

Acquisition of Metis, LLC

     On August 25, 1998, Healtheon acquired Metis, LLC, a provider of
Internet/intranet strategic consulting, design and development of Internet-based
applications and content for the healthcare industry enabling clinical
integration and managed care process improvement. The acquisition has been
accounted for using the purchase method of accounting and, accordingly, the
purchase price has been allocated to the tangible and intangible assets acquired
and the liabilities assumed on the basis of their respective fair values on the
acquisition date. Metis' results of operations have been included in the
consolidated financial statements from its date of acquisition.

     Healtheon issued 1,600,000 shares of its common stock with a fair market
value of $8,320,000. Of these shares, 476,548 shares were issued to employees
under restricted stock purchase agreements subject to a lapsing right of
repurchase, at Healtheon's option, over the respective vesting periods. In
addition, we made a cash payment of $652,000, assumed liabilities of
approximately $300,000 and incurred other acquisition related expenses,
consisting primarily of legal and other professional fees, of approximately
$100,000. The total purchase price was approximately $9,400,000. Approximately
$300,000 of the purchase price was allocated to accounts receivable and certain
assets; approximately $1,400,000 of the purchase price was allocated to the
assembled workforce of Metis and will be amortized over two years; and the
remaining $7,700,000 of the purchase price was allocated to goodwill and will be
amortized over three years.

3. SERVICES AGREEMENT WITH SMITHKLINE BEECHAM CLINICAL LABORATORIES, INC.

     Effective December 31, 1997, Healtheon entered into a series of agreements
with SmithKline Beecham Clinical Laboratories, Inc., or SmithKline Labs, to
outsource the network connection between their customers and SmithKline Labs
laboratories. In connection with this transaction, SmithKline Labs and Healtheon
entered into a five-year Services Agreement under which we will earn transaction
fee revenue by providing certain health care information services to SmithKline
Labs and its provider customers.

     As part of that transaction, we acquired a license to SmithKline Labs' SCAN
software and computer workstations that reside in various medical providers'
offices. At December 31, 1997, the SCAN license and the assets from one region
of the country were transferred to Healtheon for $2,000,000 in cash and
2,317,913 shares of Series D convertible redeemable preferred stock valued at
$8,500,000. In March and June 1998, the assets for the remaining regions of the
country were transferred to Healtheon and we paid the remaining purchase price
of $7,700,000 through the issuance of 763,548 shares of our Series D convertible
redeemable preferred stock in March and 1,336,209 shares of our common stock in
June. The value of the services agreement and the SCAN software license totaled
$14,774,000, and the value of the computer workstations totaled $3,426,000.

     In January 1999, Healtheon and SmithKline Labs entered into a services
agreement under which Healtheon will provide certain electronic laboratory
results delivery services to approximately 20,000 provider sites, in addition to
the sites currently served through the SCAN service. In addition, in January
1999, the two companies completed an asset purchase agreement under which
Healtheon purchased certain assets currently used by SmithKline Labs to provide
these laboratory results delivery services in exchange for $2,000,000 in cash
and 1,833,333 shares of Healtheon's common stock with a value of $11,000,000.

6. COMMITMENTS

     Healtheon has entered into several lease lines of credit. Lease lines
entered into totaled $3,500,000 in 1996, $2,000,000 in 1997 and $7,000,000 in
1998. Approximately $7,092,000 had been utilized under these lease lines through
December 31, 1998. At December 31, 1998, approximately $6,508,000 was available
for future utilization under these lease lines. This amount included
approximately $1,100,000 that was repaid under the terms of a revolving lease
line and is thus again available for future utilization. The arrangements are
secured by the property and equipment subject to the leases. The term of the
leases is generally three years and the interest rates implicit in the leases
range from 16.9% to 20.2% per annum. Information on payments due under these
lease lines is included in the table below under "Capital Leases."

7. BRIDGE LOANS AND NOTE RECEIVABLE FROM OFFICER

     In 1997, Healtheon borrowed $2,000,000 from certain stockholders in the
form of 6% convertible promissory notes in contemplation of the Series C
convertible preferred stock offering. These notes were converted into 800,000
shares of Series C convertible preferred stock upon the closing of that
offering. Warrants to purchase 61,947 shares of Series B convertible preferred
stock were issued in connection with the notes (see Note 10).

     In July 1997, in consideration of 250,000 shares of Series B convertible
preferred stock issued to an officer, we received a one-year, full-recourse,
noninterest-bearing promissory note for $500,000. At December 31, 1998, the note
had been paid in full.

8. LINES OF CREDIT

     In September 1997, Healtheon entered into a line of credit agreement with a
bank that allows us to borrow up to $2,101,000. Amounts borrowed under this
agreement bear interest at the bank's prime rate (7.75% at December 31, 1998).
Interest is payable monthly with payments commencing on September 30, 1997. The
line of credit availability declines over the term to $1,215,000 at December 31,
1998 and $547,000 at December 31, 1999, and expires on September 5, 2000. The
amount outstanding is collateralized by certain assets. At March 31, 1999,
$1,054,000 was outstanding under this agreement, and at December 31, 1998,
$1,213,000 was outstanding under the agreement.

     In December 1997, we entered into a loan agreement with a bank that allowed
us to borrow up to $2,250,000. Amounts borrowed under this loan agreement bore
interest at the bank's prime rate (7.75% at December 31, 1998). The loan was
personally guaranteed by a stockholder until the acquisition of ActaMed in May
1998. In May 1998, concurrent with the removal of the stockholder guarantee, the

interest rate was increased to the bank's prime rate plus 1.5%. Interest was
payable monthly with payments commencing on January 31, 1998. The principal
balance of the loan was repaid in full in August 1998.

     In February 1998, we entered into a $2,000,000 line of credit agreement
with a stockholder. We borrowed $1,000,000 under the agreement, which was repaid
with interest at 10% per annum in May 1998.

</TABLE>

     In March 1998, an additional 763,548 shares of Series D convertible
redeemable preferred stock were issued in connection with the asset acquisition
from SmithKline Labs (see Note 3).

     Dividends on each Series were cumulative whether or not declared and are
shown as a charge against income in the accompanying financial statements. On
May 19, 1998, in connection with the acquisition of ActaMed by Healtheon, the
convertible redeemable preferred stockholders waived payment of all accrued and
unpaid dividends.

     Preferred holders voted generally on an as-if converted basis. In addition,
a majority approval of the four Series was required to approve certain
transactions.

     The Series A, B, C and D cumulative convertible redeemable preferred
stockholders were entitled to receive, upon liquidation, an amount per share
equal to the issuance price, plus all accrued but unpaid dividends. Common
stockholders would then have received $5,000,000. Any remaining proceeds would
then have been distributed pro rata to the stockholders, subject only to the
Series A holders' right to receive sufficient funds to provide a 20% return on
their original investment.

     Each Series was redeemable at up to one-third of the originally issued
shares per year commencing in years six, seven and eight after the issue date at
a redemption price equal to the issue price plus all accrued but unpaid
dividends. On May 19, 1998, all outstanding shares of convertible redeemable
preferred stock were converted into 17,252,408 shares of common stock in
connection with the acquisition of ActaMed by Healtheon.

10. STOCKHOLDERS' EQUITY

Initial Public Offering

     On February 10, 1999, Healtheon completed its initial public offering. We
sold 5,750,000 shares of common stock to the public and realized net proceeds of
$41,398,000.

Convertible Preferred Stock

     In October 1998, the Board of Directors authorized 8,285,007 shares of
convertible preferred stock and designated all of these shares as Series A. In
November 1998, we issued 7,683,341 shares of Series A convertible preferred
stock for $46,101,000 of cash proceeds. The Series A convertible preferred
stockholders are entitled to non-cumulative dividends of $.405 per share per
annum, and liquidation rights per share equal to the issuance price plus all
declared but unpaid dividends. Each share of Series A preferred stock is
convertible into one share of common stock. The Series A preferred stock has
voting rights equal to the common stock issuable upon conversion. Upon the
closing of our initial public offering in February 1999, all of the outstanding
shares of Series A preferred stock were converted into shares of common stock.

     At December 31, 1997, Healtheon was authorized to issue 48,020,000 shares
of convertible preferred stock, designated in series. A summary of convertible
preferred stock was as follows:

     Series A and Series B convertible preferred shares included 20,000 and
25,000 shares, respectively, that were issued for services rendered.

     On May 19, 1998, all outstanding shares of convertible preferred stock were
converted into shares of common stock on a one-for-one basis at the election of
the holders in connection with Healtheon's acquisition of ActaMed. Concurrently
with the conversion, all outstanding warrants to purchase Series B preferred
stock were converted into warrants to purchase the same number of shares of
common stock.

     Series A, B, C and D convertible preferred stockholders were entitled to
noncumulative dividends of $0.03375, $0.135, $0.16875 and $0.351, respectively,
per share per annum. No dividends were declared through the date of conversion.
The Series A, B, C and D convertible preferred stockholders were entitled to
receive, upon liquidation, an amount per share equal to the issuance price, plus
all declared but unpaid dividends. The Series A, B, C and D convertible
preferred stockholders had voting rights equal to the common shares issuable
upon conversion.

     All outstanding shares of preferred stock were converted into common stock
in connection with our initial public offering.

Preferred Stock

     In July 1998, the Board of Directors approved a resolution authorizing
Healtheon to issue up to 5,000,000 shares of preferred stock. This resolution
became effective upon the date of our initial public offering, February 10,
1999.

Warrants

     In November 1996, Healtheon issued a warrant to a venture capital investor
to purchase 1,000,000 shares of Series B convertible preferred stock at an
exercise price of $2.00 per share for services rendered by the investor on
Healtheon's behalf. A then partner of the venture capital firm assumed the role
of President and Chief Executive Officer for Healtheon from our inception
through June 1997. The warrant was immediately exercisable and expires three
years from the date of issuance. We recorded a charge of $500,000 representing
the fair value of the warrant issued and services received based on a valuation
obtained from an independent appraiser utilizing a modified Black-Scholes option
pricing model. This warrant was outstanding at December 31, 1997 and in May 1998
was converted to a warrant to purchase common stock. It remained outstanding at
December 31, 1998.

     In November 1996, we granted a warrant to one of our directors to purchase
1,000,000 shares of Series B convertible preferred stock at an exercise price of
$2.00 per share, the fair value of Series B convertible preferred stock at the
date of issuance. The warrant vests over a period of 18 months from the date of
issuance. The term of the warrant is three years. This warrant was outstanding
at December 31, 1997 and was exercised in full in May 1998.

     In December 1996, we issued a warrant to a customer to purchase 282,522
shares of common stock at a price of $7.97 per share. The warrant expires in
December 2001. This warrant was outstanding at December 31, 1998.

     In July 1997, we issued a warrant to an officer, in connection with his
employment, to purchase 750,000 shares of Series B convertible preferred stock
at an exercise price of $2.00 per share, the fair value of Series B convertible
preferred stock at the date of issuance. The warrant expires three years from
issuance, and shares purchased under the warrant are subject to repurchase by
Healtheon, at our option, upon termination of employment. Shares under the
warrant vest ratably over a period of two years from the date of grant. This
warrant was outstanding at December 31, 1997 and in May 1998 was converted to a
warrant to purchase common stock. It remained outstanding at December 31, 1998.

     In July 1997, we issued warrants to purchase a total of 61,947 shares of
Series B convertible preferred stock to certain investors in connection with a
bridge financing. The warrants expire four years from issuance and are
exercisable at $2.00 per share. The value of these warrants, approximately
$64,000, was expensed as a cost of financing. All of these warrants were
outstanding at December 31, 1997. In May 1998, warrants to purchase 17,229
shares of Series B convertible preferred stock were exercised and the remainder
of the warrants, which were outstanding at December 31, 1998, were converted to
warrants to purchase 44,718 shares of common stock.

     In December 1998, as part of a service agreement with a customer, we issued
to the customer a warrant to purchase 500,000 shares of common stock with an
exercise price of $10.40 per share. The warrant vests as to 200,000 shares in
December 1999 and as to an additional 100,000 shares in December 2000, 2001 and
2002. The warrant expires in March 2003.

     At December 31, 1998, we had reserved 2,577,240 shares of our common stock
for issuance upon exercise of the outstanding warrants for common stock.

11. STOCK-BASED COMPENSATION

Stock Option Plans

     Under the 1996 Stock Plan, or the 1996 Plan, which was adopted in February
1996, the Board of Directors may grant options to purchase common stock or issue
common stock subject to a restricted stock

purchase agreement to eligible participants. Options granted may be either
incentive stock options or nonstatutory stock options and are exercisable within
the times or upon the events determined by the Board of Directors as specified
in each option agreement. Options vest over a period of time as determined by
the Board of Directors, generally four years. The term of the 1996 Plan is ten
years. At December 31, 1998, a total of 15,000,000 shares had been reserved
under the 1996 Plan and 1,237,424 shares remained available for future grant
under the 1996 Plan. The number of shares reserved under the 1996 Plan is
subject to an annual increase equal to the lesser of 5% of the outstanding
common shares or a lesser amount determined by the Board of Directors. In
January 1999, an additional 3,107,321 shares were reserved under the 1996 Plan
under the annual increase provision. In February 1999, the Board of Directors
and the stockholders approved an amendment to increase the number of shares
reserved for issuance under the 1996 Plan by an additional 1,000,000 shares.

     On October 20, 1998, we offered our employees who were granted options from
July 1998 through October 1998 the ability to cancel their original option grant
in exchange for a new option agreement with a new vesting start date and an
option price of $3.55 per share. A total of 3,380,200 option shares with
exercise prices of $4.50, $6.30, $7.00 and $8.00 were eligible to be repriced. A
total of 2,057,950 option shares were cancelled and reissued.

     In connection with the acquisition of ActaMed, Healtheon assumed all the
outstanding options issued under the ActaMed stock option plans, after the
application of the exchange ratio, and reserved 3,100,489 shares of common stock
for issuance upon exercise of the assumed options. No further options can be
granted under these plans. At the time of the acquisition, options for 2,717,269
shares were fully vested. The remainder of the shares vest based upon annual
cliffs over a five-year period from the date of grant.

     Shares issued subject to restricted stock purchase agreements totaled
1,098,732 in 1998, 850,000 in 1997 and 1,806,000 in 1996. All of these shares
were issued to employees for cash. The common stock is subject to repurchase at
the original exercise price until vested, at our option. The shares vest over a
period of time as determined by the Board of Directors for each individual
purchase agreement, generally four years. During 1998, 259,896 shares were
repurchased from terminated employees and 613,542 shares were repurchased in
1997. In addition, on December 14, 1998, 455,000 shares of common stock issued
in July 1998 subject to restricted stock purchase agreements were rescinded as
part of the repricing program. Shares subject to repurchase totaled
approximately 1,247,000 at December 31, 1998, approximately 1,430,000 at
December 31, 1997 and approximately 1,660,000 at December 31, 1996.

between the exercise price and the deemed fair value of our common stock on the
date the stock options were granted. We recorded amortization of deferred stock
compensation of approximately $2,084,000 in the three months ended March 31,
1999, $3,376,000 in 1998 and $562,000 in 1997 based on a graded vesting method.
At March 31, 1999, we had a total of approximately $11,112,000 remaining to be
amortized on a graded vesting method over the corresponding vesting period of
each respective option, generally four years.

Pro Forma Information

     We have elected to follow APB No. 25 and related interpretations in
accounting for our employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS No. 123 requires use
of option valuation models that were not developed for use in valuing employee
stock options. Under APB No. 25, no compensation expense is recognized when the
exercise price of stock options granted to our employees equals the market price
of the underlying stock on the date of grant.

     Pro forma information regarding net loss is required by SFAS No. 123 and
has been determined as if employee stock options granted subsequent to December
31, 1994 were accounted for under the fair value method of SFAS No. 123. The
fair value for these options was estimated at the date of grant using the
minimum value method with the following weighted-average assumptions: risk-free
interest rate of approximately 4.9% in 1998, 6.0% in 1997 and 6.0% in 1996; a
weighted-average expected life of the option of 3.5 years in 1998, 4.2 years in
1997 and 4.3 years in 1996; and a dividend yield of zero for all years.

Employee Stock Purchase Plan

     In September 1998, the Board of Directors approved and in October 1998, the
stockholders also approved the adoption of Healtheon's 1998 Employee Stock
Purchase Plan, or the 1998 Purchase Plan. The 1998 Purchase Plan became
effective on the effective date of our initial public offering, February 10,
1999. A total of 1,000,000 shares of common stock has been reserved for issuance
under the 1998 Purchase Plan, plus annual increases equal to the lesser of
500,000 shares, 0.5% of the outstanding common shares or a lesser amount
determined by the Board of Directors.

12. INCOME TAXES

     Deferred income taxes reflect the net tax effects of temporary differences

</TABLE>

     A valuation allowance equal to 100% of the net deferred tax assets has been
established because of the uncertainty of realization of the deferred tax assets
due to our lack of earnings history. The valuation allowance for deferred tax
assets increased by $21,599,000 in 1998, $9,386,000 in 1997 and $6,580,000 in
1996.

     At December 31, 1998, we had net operating loss carryforwards for federal
income tax purposes of approximately $76,500,000, which expire in 2009 through
2018, and federal tax credits of approximately $1,800,000, which expire in 2009
through 2018.

     Approximately $19,890,000 of the net operating loss carryforwards at
December 31, 1998 related to a consolidated subsidiary. This loss carryforward
is only available to offset future taxable income of that subsidiary.

     Because of the "change of ownership" provisions of the Internal Revenue
Code, a portion of our net operating loss carryforwards and tax credit
carryforwards may be subject to an annual limitation regarding their utilization
against taxable income in future periods. A portion of these carryforwards may
expire before becoming available to reduce future income tax liabilities.

13. RELATED PARTY TRANSACTIONS

     Healtheon has two customers that are significant stockholders of Healtheon.

     We entered into a Development Agreement with a partnership controlled by
the former Chairman of the Board of Directors of ActaMed. Under this agreement,
we granted the partnership exclusive licenses to use ActaMed's technology for
industries other than the healthcare industry. Under the agreement, we will
receive a commercial royalty on the partnership's gross receipts. If we desire
in the future to expand to other industries, the partnership must either develop
that industry in a defined time period or rights to that industry revert to
Healtheon. The agreement expired unexercised on December 3, 1998. No fees were
paid to Healtheon under this agreement.

     We share office space and provide administrative support and network
resources to a company controlled by a member of the Board of Directors. Amounts
reimbursed for the shared facilities and administrative support totaled
approximately $80,000 in 1998, $46,000 in 1997 and $58,000 in 1996.
Approximately $124,000 in 1998, $78,000 in 1997 and $187,000 in 1996 was
reimbursed for the use of the network maintained by Healtheon. All of the
amounts reimbursed are included as an offset to general and administrative
expenses in the accompanying consolidated statements of operations. Amounts due
from the related party of $40,000 at December 31, 1998 and $72,000 at December
31, 1997 were included in other current assets in the accompanying consolidated
balance sheets.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
WebMD, Inc.

     We have audited the accompanying consolidated balance sheets of WebMD, Inc.
(formerly Endeavor Technologies, Inc.) and subsidiaries as of December 31, 1997
and 1998, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
WebMD, Inc. and subsidiaries at December 31, 1997 and 1998, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1998, in conformity with generally accepted accounting
principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS

     Endeavor Technologies, Inc., a Georgia corporation, was formed on October
17, 1996 and was renamed WebMD, Inc. (the "Company") in August 1998. In the
fourth quarter of 1998, the Company launched a branded, integrated, Web-based
solution for the administrative, communications and information needs of
healthcare professionals and for the healthcare information needs of consumers.

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. On March 26, 1997, the Company acquired
Quality Diagnostic Services, Inc. ("QDS"). The assets and liabilities of QDS
were acquired in a transaction accounted for as a reverse acquisition/
recapitalization and are recorded at historical cost. Additionally, the results
of operations of the combined companies are reflected as if the above
transaction took place at January 1, 1996. All significant intercompany accounts
and transactions have been eliminated in consolidation. Consequently, for
comparative purposes, the combined financial statements have been presented as
if the Company and its subsidiaries were a single entity for the periods
presented.

     Effective July 1, 1997, the Company sold all of the outstanding stock of
UltraScan, Inc. ("UltraScan") for $400.

     Effective July 1, 1998, the Company sold substantially all of the assets of
QDS and Telemedics, Inc. ("Telemedics") for $17,000 in cash and up to $6,000 in
additional contingent consideration based on 1999 QDS and Telemedics revenues.
No contingent consideration has been recorded as of December 31, 1998.

     The consolidated financial statements reflect the results of UltraScan,
QDS, and Telemedics as discontinued operations. See Note 2 for further
discussion.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and the
accompanying notes. Actual results could differ from these estimates.

CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

CONCENTRATION OF CREDIT RISK

     Financial instruments, which potentially subject the Company to significant
concentrations of credit risk, consist principally of cash and cash equivalents.
The Company maintains cash and cash equivalents with two separate financial
institutions located in Georgia. At December 31, 1998, substantially all of the
Company's cash and cash equivalents are invested in short-term money market
accounts, which bear minimal risk, and are available on demand.

     The carrying amount reported in the balance sheet for cash and cash
equivalents and accounts payable approximate their fair values due to the
short-term nature of these financial instruments. The carrying amount reported
in the balance sheet for long-term debt approximates its fair value based on
discounted cash flows.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1998
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

VULNERABILITY DUE TO CERTAIN CONCENTRATIONS

     The Company is dependent upon various content providers to provide content
for use on the Company's Web site.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost less accumulated depreciation.
Depreciation is provided using the straight-line method over the estimated
useful lives of the respective assets, generally three to seven years.

PRODUCT DEVELOPMENT AND CONTENT COSTS

     Product development and content costs include personnel costs associated
with the development, management, testing and upgrades to the Company's Web site
and systems, license fees for content acquisition and third party Web site
development services. Product development costs are charged to operations as
incurred. Content costs are amortized over the useful life of the content or
over the term of the content license agreement on a straight line basis.

     Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed,"
requires the capitalization of certain software development costs subsequent to
the establishment of technological feasibility. Based upon the Company's product
development process, technological feasibility is established upon the
completion of a working model. Costs incurred by the Company between completion
of a working model and the point at which the product is ready for general
release have not been significant.

ADVERTISING COSTS

     Advertising costs are charged to expense in the period the costs are
incurred. Advertising expense for the years ended December 31, 1996, 1997 and
1998 was $0, $164 and $604, respectively.

INCOME TAXES

     Income taxes have been provided using the liability method in accordance
with SFAS No. 109, "Accounting for Income Taxes."

REVENUE RECOGNITION

     The Company derives revenue from its subscriptions. Revenues from
subscriptions are deferred and recognized ratably over the term of the
subscription. Revenues related to the Company's various Internet-based
administrative, communication and information services are recognized when the
services are provided.

STOCK SPLIT

     On October 2, 1997, the Company effected a one-for-two reverse stock split.
The share and per share amounts in the financial statements have been
retroactively adjusted for the reverse stock split.

NET LOSS PER SHARE

     In 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"),
and in February 1998, the

                                      F-39

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1998
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

Securities and Exchange Commission issued Staff Accounting Bulletin ("SAB") No.
98 related to SFAS 128. SFAS 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share. Unlike
primary earnings per share, basic earnings per share excludes any dilutive
effects of options, warrants and convertible securities. Diluted earnings per
share is similar to the previously reported fully diluted earnings per share.
The Company's common stock equivalents were antidilutive and therefore were not
included in the computation of weighted average shares used in computing diluted
loss per share.

     Options and warrants to purchase 4,510,321 and 8,160,309 shares of common
stock with a weighted average exercise price of $1.20 and $4.59 per share,
outstanding in 1997 and 1998, respectively, and 30,000 shares of restricted
common stock issued during 1998 were not included in the computation of diluted
loss per share because the Company reported a loss and, therefore, the effect
would be antidilutive.

STOCK BASED COMPENSATION

     Statement of Financial Accounting Standards No. 123, "Accounting for Stock
Based Compensation" ("SFAS 123") sets forth accounting and reporting standards
for stock-based employee compensation plans. As permitted by SFAS 123, the
Company continues to account for stock option grants in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees", and related interpretations (collectively "APB 25"). Under APB 25,
no compensation expense is recognized for stock options granted to employees at
fair market value. Certain stock, stock options and warrants were granted with
exercise prices below the then fair market value or at fair market value to
third parties. In connection with these issuances, the Company recognized
$1,371, $11 and $3,226 in compensation expense during 1996, 1997 and 1998,
respectively.

RECLASSIFICATIONS

     Certain reclassifications have been made to the 1997 financial statements
to conform with the 1998 presentation.

UNAUDITED FINANCIAL STATEMENTS

     The accompanying unaudited financial statements as of March 31, 1999 and
for the three months ended March 31, 1998 and 1999 have been prepared on a basis
substantially the same as the audited financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the financial information set forth therein.

2. DISCONTINUED OPERATIONS

     Effective July 1, 1998, the Company sold substantially all of the assets of
QDS and Telemedics. The sale resulted in a net gain of $7,709. In connection
with the sale, the Company has issued a warrant to purchase 80,000 shares of the
Company's Series D common stock (see Note 10). The operations of these
subsidiaries are included in the statements of operations as a loss from
discontinued operations. Net patient service revenues from QDS for the years
ended December 31, 1996, 1997 and for the period from January 1, 1998 to July 1,
1998 were approximately $3,257, $7,091 and $5,261, respectively. Product sales
from Telemedics for the year ended December 31, 1997 (the first year of
operations) and for the period from January 1, 1998 to July 1, 1998 were
approximately $283 and $26, respectively. Net losses for QDS and Telemedics
combined for the years ended December 31, 1996 and 1997 and for the period from
January 1, 1998 to July 1, 1998 were $1,645, $778 and $393, respectively.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

     QDS revenues from arrhythmia monitoring services were recognized as the
services were performed over the contract term. Telemedics product sales revenue
from the sale of arrhythmia monitoring devices were recognized upon shipment.
Net patient service revenues for QDS were reported at the estimated net
realizable amounts from third-party payors and others for services rendered.
Contractual allowances were reflected as a reduction in gross charges to arrive
at net patient service revenue. An allowance for doubtful accounts was
established for revenue estimated to be uncollectible and adjusted based upon
management's evaluation of current economic conditions, historical collection
experience and other relevant factors that, in the opinion of management,
required recognition in estimating such allowance.

     Effective July 1, 1997, the Company sold all of the outstanding shares of
common stock of Ultrascan to its former President. The sale resulted in a net
gain of approximately $165. The operations of this subsidiary are included in
the statements of operations as a loss from discontinued operations. Revenue and
net losses from Ultrascan for the year ended December 31, 1996 and the six month
period ended June 30, 1997, were approximately $13 and $189 and $37 and $417,
respectively. As of December 31, 1998, a note receivable of $134 is due from the
purchaser related to this sale.

     Balance sheet information for QDS, Telemedics and Ultrascan is provided as

     The net increases in cash balances associated with the discontinued
operations were $139, $53 and $62 during the years ended December 31, 1996, 1997
and the period from January 1, 1998 through June 30, 1998, respectively, and
have been reflected in cash flows from operating activities of discontinued
operations.

     In connection with the acquisition of QDS by the Company, certain
shareholders of QDS asserted their rights granted under Georgia law to dissent
with regard to such action and to demand payment for the fair value of their
shares in exchange for the surrender of such shares. In accordance with Georgia
law, the Company offered to pay the former shareholders approximately $400 for
their interest in QDS. The former shareholders rejected that offer. On August 1,
1997, in accordance with statutory provisions relating to the valuation process,
QDS filed a complaint against the dissenting shareholders for the judicial
appraisal of their shares. In July 1998, the Company paid the former
shareholders of QDS approximately $2,700 in settlement of the dissenters' rights
action. This payment is reflected as a reduction to the gain on disposal of
discontinued operations.

3. ACQUISITION

     In December 1998, the Company acquired substantially all of the net assets
of certifiedemail.com, Inc. ("certifiedemail.com") for 50,000 shares of the
Company's Series D common stock. In connection

with the acquisition, the Company assumed accounts payable of approximately $100
and forgave a note receivable from certifiedemail.com for approximately $230.
The acquisition has been accounted for as a purchase and the excess of cost over
fair value of the net assets acquired of approximately $1,060 has been recorded
as goodwill and is being amortized on a straight-line basis over a three-year
period. Pro forma results are not presented for this acquisition as they are not
significant during the years presented.

5. WRITE-DOWN OF CUSTOMER TERMINALS

     During 1998, the Company purchased customer terminals which were to be
included as promotional arrangements with certain subscribers. Due to a change
in the Company's strategy, the Company recorded a charge of approximately $1,795
to write-down customer terminals to their net realizable value of $620. The net
realizable value, which was determined by a third party offer, is included in
other assets.

6. COMMITMENTS

CONTENT AND STRATEGIC ALLIANCE COMMITMENTS

     The Company has agreements with various content providers and strategic
partners whereby the Company is committed to pay certain amounts in connection
with content and services obtained for use on the Company's Web site and certain
distribution arrangements. The Company has recorded $538 and $1,122 as product
development and content costs related to these agreements during 1997 and 1998,

recorded this obligation in prepaid software licenses and accrued expenses.

OPERATING LEASE COMMITMENTS

     The Company leases its facilities and certain office equipment under
operating lease agreements expiring through 2001. Lease expense was
approximately $204 and $541 for the years ended December 31, 1997 and 1998,

     Additionally, certain UltraScan equipment leases with total lease
commitments of $678 as of December 31, 1998, are under guarantee by the Company.
These leases expire through 2002.

     In April 1998, a primary vendor of QDS and Telemedics took occupancy of
space previously occupied by the Company under a sublease agreement for which
the Company is a guarantor. Total lease commitments under this lease as of
December 31, 1998 are $326 and the lease expires in 2001.

7. LONG-TERM DEBT

     During 1997 the Company borrowed $4,000 from Sirrom Capital Corporation
("Sirrom"), with interest payable monthly at 13.5%, and principal due on August
1, 2002. On July 8, 1998, the Company borrowed an additional $2,000 from an
affiliate of Sirrom, Sirrom Investment, Inc. Finance costs related to the
initial Sirrom debt instrument totaling $124 were capitalized during 1997 and
amortized over five years. On July 22, 1998, the Company repaid all outstanding
borrowings from Sirrom. In connection with the retirement of these borrowings,
the Company recognized an extraordinary loss of $930, which included the
remaining balance of the capitalized finance costs.

8. RETIREMENT PLAN

     The Company has a defined contribution 401(k) plan. The plan is for the
benefit of generally all employees 21 years of age or older with at least six
months of employment and permits voluntary employee contributions and Company
profit sharing contributions. The Company has not made any such contributions to
the plan through December 31, 1998.

9. RELATED PARTY TRANSACTIONS

     In August 1996, QDS received a $200 loan from a shareholder for working
capital needs. The indebtedness bore no interest and was payable on demand. In
February 1998, the Company converted the indebtedness into 100,000 shares of
Series D common stock.

     In August 1997, the Company received loans of $100 each from two
shareholders of the Company. Each unsecured loan was evidenced by a promissory
note payable and paid in full during 1997. In conjunction with these loans, the
Company granted each of the two shareholders the option to purchase

13,486 shares of Series D common stock of the Company at an exercise price of
$1.44 per share. In connection with these options, the Company recorded their
fair value, as determined by the minimum value method, as additional interest
expense.

     During 1998, the Company purchased services from iXL Enterprises, Inc.
("iXL") in the amount of $4,448. A board member of the Company is Chairman of
iXL.

10. SHAREHOLDERS' EQUITY

COMMON STOCK

     As discussed in Note 1, the merger between the Company and QDS has been
accounted for as a reverse acquisition/recapitalization and, as a result, for
comparative purposes, the financial statements, including equity transactions,
have been presented as if the Company and QDS were a single entity for all
periods presented. Shares were issued to founders of Endeavor in exchange for
nominal consideration.

     In October 1998, the Company issued 30,000 shares of its Series D common
stock in exchange for corporate communication services to be provided through
April 1999. The Company has recorded the shares at $405, which approximated
their fair market value on the date of issuance, and is amortizing the value to
sales and marketing expense over the term of the agreement. During 1998, the
Company recorded $270 of sales and marketing expense related to this agreement.

     The Company has authorized and issued shares of common stock (no
designation), Series B, C, D and E common stock. The rights of the series are
identical except that (i) Series B, C, D and E common stock are non-voting and
(ii) Series B, C and E common stock have a liquidation preference of $0.29,
$1.00 and $1.00 per share, respectively. Upon a liquidation of the Company, if
the assets of the Company are insufficient to permit full payment of the
liquidation preference after payment of preferred stock liquidation preference,
then the assets of the Company available for such distribution shall be
distributed pro rata based on the relative liquidation preferences.

     Upon the effective date of a public offering of the Company's common stock,
the common stock (no designation) Series B, C, D and E common stock will be
automatically converted into one series of voting common stock.

PREFERRED STOCK

     The Company's Board of Directors has authorized 10,000,000 shares of
preferred stock, with 1,600,000 of such shares designated as Series A preferred
stock, 3,400,000 of such shares designated as Series B preferred stock,
2,000,000 of such shares designated as Series C preferred stock, 200,000 of such
shares designated as Series D preferred stock, 792,000 of such shares designated
as Series E preferred stock, and 1,180,000 of such shares designated as Series F
preferred stock.

     During 1998, the Company sold 801,000 shares of its Series A preferred
stock for $15.00 per share. In connection with the sale of the Series A
preferred stock, the Company has agreed to issue additional shares of Series A
preferred stock should the Company not complete an initial public offering by
certain dates as follows: 30,000 shares on March 1, 1999, 150,000 shares on May
22, 1999, 10,000 shares on September 1, 1999 and 50,000 shares on November 22,
1999.

     As described in the Company's Articles of Incorporation, the holders of
Series A, B and C preferred stock have the right to convert all or part of such
shares into common stock on a one-for-one basis. The holders of Series D
preferred stock have the right to convert all or part of such shares into common
stock under certain circumstances, as defined in the Articles of Incorporation
on a five-for-one basis. The holders

</TABLE>

STOCK WARRANTS

     On August 29, 1997, the Company borrowed $4,000 from Sirrom. In connection
with the loan, Sirrom received a warrant to purchase 771,901 shares of the
Company's Series D common stock for $0.01 per share. Of the $4,000 in
borrowings, $1,110 was allocated to the value of the warrant and recorded as a
separate component of equity. The warrant expires on August 1, 2002. In
connection with the warrant, $75 and $105 was amortized to interest expense
during 1997 and 1998, respectively.

     Sirrom has the option to require the Company to redeem the warrants for a
period of 30 days after the exercise period in August 2002, at a purchase price
equal to fair market value, as defined. Upon completion of an initial public
offering by the Company, the redemption right terminates. Accordingly, in
periods prior to an initial public offering, the Company has accounted for the
warrants as temporary equity. The excess of the redemption value over the
carrying value is being accrued by periodic charges to accumulated deficit over
the redemption period. This accrual amounted to $2,150 for 1998. Upon the
exercise or completion of an initial public offering, the value of the warrants
will be transferred to permanent equity.

     In December 1997, the Company granted a warrant to purchase 1,384,600
shares of the Company's Series E common stock for $1.44 per share to Premiere
Technologies, Inc. ("Premiere"). The warrant was issued in connection with a
sale of the Company's Series E common stock and the fair value of the warrant of
$45 was recorded as issuance cost. On April 29, 1998, Premiere exercised its
option in full.

     In connection with the sale of QDS and Telemedics, the Company issued a
warrant to purchase 110,768 shares of the Company's Series D common stock to
Matria at the lesser of $14.44 or the initial public offering price should the
Company complete an initial public offering. The warrant will be exercisable in
full on the earlier of the completion of an initial public offering or June 30,
1999 and expires five years from the issuance date.

     In connection with sales of its Series A preferred stock, the Company also
issued warrants to purchase a total of 498,456 shares of the Company's Series A
preferred stock at the lesser of the price at a

public offering or $13.00 per share. The warrants expire on August 24, 2001 with
respect to 415,380 shares and on September 1, 2001 with respect to 83,076
shares.

STOCK OPTION PLAN

     Effective January 1, 1997, the Board of Directors and shareholders of the
Company adopted the 1997 Stock Incentive Plan (the "1997 Plan"), which provides
for issuance of stock options and restricted stock awards to employees,
directors, consultants and advisors. The Board of Directors and shareholders of
the Company amended and restated the 1997 Plan on September 17, 1998. Options
may be granted under the 1997 Plan with an exercise price not less than the fair
value of the Company's common stock on the date of the grant, as determined by
the Board of Directors or a committee of the Board, in the absence of a readily
available market for the Company's stock. Options become exercisable and expire
as determined by the Board of Directors or a committee of the Board (generally
over 2 to 7 years).

     Effective November 13, 1998, the Board of Directors and shareholders of the
Company adopted the Director Stock Option Plan ("the Director Plan"), which
provides for issuance of stock options to non-employee directors. Options are
granted automatically to existing directors on the date of adoption and
subsequently upon election as a director of the Company and at January 1 of each
calendar year with an exercise price not less than the fair value of the
Company's common stock on the date of the grant. Options are vested immediately
and become exercisable six months from the date of grant and expire in ten
years.

     Pro forma information regarding net income and loss per share is required
by SFAS 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method. The fair value for these
options was estimated at the date of grant using a minimum value pricing model
with the following weighted average assumptions for 1997 and 1998: risk-free
interest rates of 6.2% and 5.4%; no dividend yield; and an expected life of an
option of four years.

     Option valuation models used under SFAS 123 were developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require input
of highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

     For purposes of pro forma disclosures, the estimated fair value of the
options granted to employees are amortized to expense over the vesting period.
The weighted average fair value per option granted in 1997 and 1998 was $0.32
and $1.56, respectively. The Company's pro forma net loss would have been
$(4,514) and $(17,173) and net loss per share would have been $(0.54) and
$(1.40), for the years ended December 31, 1997 and 1998, respectively.

     Certain options and warrants were issued with exercise prices below the
then fair market value or were issued at fair market value to third parties. In
connection with these issuances, the Company recognized $11 and $3,226 in
compensation expense during 1997 and 1998, respectively. Certain sales
representatives of the Company entered into agreements that did not fix the
number of options to purchase shares until certain goals are met. Because the
exercise price of these options is fixed but the number of shares is variable,
the Company recorded compensation expense relating to these options to the
extent the fair market value of the underlying stock was in excess of the
exercise price at the time the number of shares was determined. All options
issued to sales representatives were fixed during 1998 and thus the number of
shares became determinable.

</TABLE>

     At December 31, 1998 the Company has total net operating loss carryforwards
for federal and state income tax purposes of approximately $13,721 that expire
in years 2010 through 2013.

     Utilization of the Company's net operating loss carryforwards may be
subject to an annual limitation due to the "change of ownership" provisions of
the Internal Revenue Code and similar state provisions. The annual limitation
may result in the expiration of net operating losses and credits before
utilization. For financial reporting purposes, a valuation allowance has been
recognized to reduce the net deferred tax assets to zero due to uncertainties
with respect to the Company's ability to generate taxable income in the future
sufficient to realize the benefit of deferred income tax assets.

Strategic Relationships and Distribution Agreements and other Equity
Transactions

     In April 1999, Sirrom exercised its warrant to purchase 771,901 shares of
common stock.

     Subsequent to year end, the Company entered into various agreements with
service and content providers and distribution partners whereby the Company has
committed to pay certain amounts in connection with content and services
obtained for use on the Company's Web site and certain distribution
arrangements.

     During the first quarter of 1999, the Company sold approximately 1.7
million shares of common and preferred stock for approximately $34,000.

     On January 27, 1999, the Company issued warrants to purchase 1,038,450
shares of Series D common stock to Gleacher NatWest, Inc. ("Gleacher NatWest").
These warrants vest 692,300 on January 29, 1999 and 346,150 on January 29, 2000
and have an exercise term of five years. The agreement requires Gleacher NatWest
to perform financial advisory services over a two year period. If Gleacher
NatWest fails to perform under the agreement, they forfeit the unvested options
and pay the Company a cash penalty.

     On March 1, 1999, the Company issued 200,000 shares of Series D preferred
stock in connection with a strategic alliance, which is convertible into
1,000,000 shares of common stock. The value attributed to this issuance was

$1,865 was attributable to related parties.

of the Company's stock. The transaction is preliminarily valued at approximately
$6,671,600. The acquisition, which is expected to be accounted for using the
purchase method of accounting, is anticipated to be completed in the third
quarter of 1999.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
MEDE America Corporation

     We have audited the accompanying consolidated balance sheets of MEDE
America Corporation and subsidiaries (the "Company") as of June 30, 1997 and
1998, and the related consolidated statements of operations, stockholders'
equity (deficit) and cash flows for each of the three years in the period ended
June 30, 1998. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of MEDE America Corporation and
subsidiaries as of June 30, 1997 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1998 in conformity with generally accepted accounting principles.

     As discussed in Note 13, the accompanying 1997 and 1998 consolidated
financial statements have been restated.

                   MEDE AMERICA CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                    YEARS ENDED JUNE 30, 1996, 1997 AND 1998
                 AND NINE MONTHS ENDED MARCH 31, 1998 AND 1999
     (INFORMATION AS IT RELATES TO THE NINE MONTHS ENDED MARCH 31, 1998 AND
                               1999 IS UNAUDITED)

1. DESCRIPTION OF PRESENTATION, BASIS OF PRESENTATION, AND
   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a. Description of Business -- MEDE America Corporation and subsidiaries
(the "Company") is a leading provider of electronic data interchange ("EDI")
products and services to a broad range of providers and payors in the healthcare
industry. The Company's integrated suite of EDI products and services permits
hospitals, pharmacies, physicians, dentists, and other healthcare providers and
provider groups to electronically edit, process and transmit claims, eligibility
and enrollment data, track claims submissions through the claims payment process
and obtain faster reimbursement for their services.

     b. Basis of Presentation -- The accompanying consolidated financial
statements include the accounts of MEDE America Corporation and its wholly-owned
subsidiaries: MEDE America, Inc. ("MEDE"), Medical Processing Center, Inc.
("MPC"), Wellmark Incorporated ("Wellmark"), Electronic Claims and Funding, Inc.
("EC&F"), Premier Dental Systems Corp. ("Premier"), Healthcare Interchange, Inc.
("HII"), and MEDE America Corporation of Ohio, Inc. ("MEDE OHIO") (formerly
General Computer Corporation). MPC, Wellmark, and MEDE formerly constituted the
healthcare information services business unit of Card Establishment Services
("CES"). On March 9, 1995, CES was acquired by First Data Corporation. Prior to
this transaction, the former owners of CES spun off the healthcare information
services business unit as a new company with MEDE America Corporation formed to
serve as the holding company (the "Spin-off"). Because there was no change in
ownership as a result of this Spin-off, the accompanying consolidated financial
statements accounted for MEDE, MPC, and Wellmark on an historical cost basis.
Effective July 1, 1997, MEDE, MPC, Wellmark, and EC&F were merged into MEDE
America Corporation.

     The Company has instituted certain cost reduction programs. The Company
anticipates that these programs, when coupled with the Company's revolving
credit facility, will enable the Company to satisfy its short-term cash flow and
working capital requirements at least through fiscal 1999. Additionally, the
Company has received support from certain of its stockholders in the past and
believes that continued support would be available if necessary to meet cash
flow and working capital requirements. However, such stockholders are under no
legal obligation to provide such support and, given the successful consummation
of the IPO (as herein defined), such stockholders may elect not to do so (see
Note 8).

     On February 5, 1999, the Company consummated an initial public offering
("IPO") of 5,307,710 shares of common stock at a price of $13.00 per share
(including 692,310 shares that were subject to the underwriters' overallotment
option, which was exercised in full). The net proceeds to the Company were
approximately $61,868,000 (after deducting the underwriting discount and
offering expenses payable by the Company). The net proceeds to the Company were
used to (i) prepay approximately $25,236,000 of outstanding principal and
accrued interest on its outstanding 10% Senior Subordinated Note due February 1,
2002 and (ii) repay approximately $28,261,000 of outstanding indebtedness and
accrued interest under its revolving credit facility (the "Credit Facility").
The remaining $8,371,000 of net proceeds was used to pay a portion of the
accrued dividends on the Company's preferred stock, and the remainder of such
accrued dividends (approximately $301,000) was converted into 23,124 shares of
Common Stock. In addition, in connection with the IPO, all outstanding shares of
preferred stock were converted into 1,845,815 shares of common stock at the IPO
price of $13.00 per share.

                   MEDE AMERICA CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     In connection with the prepayment of the Senior Subordinated Note and the
establishment of the New Credit Facility (as defined herein), the Company
recorded an extraordinary charge of approximately $1.6 million relating to the
write-off of the remaining discount on the Senior Subordinated Note and deferred
financing costs.

     c. Principles of Consolidation -- All significant intercompany transactions
and balances are eliminated in consolidation.

     d. Revenue Recognition -- Transaction and related formularly services
revenues (if applicable) are recognized at the time the transactions are
processed and the services are rendered. Other service revenues (including
post-contract customer support) and other revenues (including revenues relating
to insignificant obligations at the time sales are recorded) are recognized
ratably over applicable contractual periods or as service is provided. Revenue
from the licensing of software is recognized only after it is determined that
the Company has no significant remaining obligations and that collectibility of
the resulting receivable is probable. Revenue from hardware sales is recognized
when the hardware is shipped.

     e. Cash and Cash Equivalents -- The Company considers all highly liquid
instruments with original maturity dates of three months or less to be
components of cash and cash equivalents.

     f. Accounts Receivable -- Accounts receivable are due primarily from
companies in the healthcare industry. Credit is extended based on an evaluation
of the customer's financial condition, and generally collateral is not required.

     g. Formularly Receivables -- Formularly receivables represent amounts due
for pharmacy related services provided to Practice Benefit Management ("PBM")
clients. Services include prescription processing from EDI transactions and
collecting and distributing pharmaceutical company fees for sponsored programs
to the PBM client. The Company submits processed transactions qualifying for
formularly incentive fees to various intermediaries who have PBM program
services contracts with pharmaceutical manufacturers on a quarterly basis, in
arrears. The intermediaries consolidate formularly transactions from various
processors and, in turn, submit such transactions to the pharmaceutical
manufacturers for payment. The additional processing and reconciliation time of
the consolidators and pharmaceutical companies results in a collection cycle for
the Company of 7-12 months.

     h. Inventory -- Inventory is stated at the lower of cost (first-in,
first-out) or market.

     i. Property and Equipment -- Property and equipment is stated at cost less
accumulated depreciation and amortization, and is depreciated using the
straight-line method over the estimated useful lives of the related assets.

     j. Goodwill -- Goodwill represents the excess of cost over the fair value
of net assets acquired and is amortized on a straight-line basis over 7 to 20
years. Accumulated amortization amounted to $3,451,000 and $5,864,000 as of June
30, 1997 and 1998, respectively.

     k. Other Intangible Assets -- Other intangible assets include purchased
client lists, purchased software and technology, and capitalized software
development costs. Purchased client lists are amortized on a straight-line basis
over three to five years. Amortization of purchased software and technology and
of capitalized software development costs is provided on a product-by-product
basis at the greater of the amount computed using (a) the ratio of current
revenues for a product to the total of current and anticipated future revenues
or (b) the straight-line method over the remaining estimated economic life of
the product. Generally, an original estimated economic life of three to five
years is assigned to purchased software and technology and an original estimated
economic life of five years is assigned to capitalized software development
costs. Amortization begins in the period in which the related product is
available for general release to customers.

                                      F-57

                   MEDE AMERICA CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     l. Software Development Costs -- The development of new software products
and enhancements to existing software products are expensed as incurred until
technological feasibility has been established. After technological feasibility
is established, any additional costs are capitalized in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting For the
Cost of Computer Software To Be Sold, Leased or Otherwise Marketed." During the
year ended June 30, 1998, the Company capitalized $462,000 of software
development costs on a project for which technological feasibility had been
established but was not yet available for customer release. Prior to July 1,
1997, the Company did not have any software development projects for which
significant development costs were incurred between the establishment of
technological feasibility and general customer release of the product.

     m. Impairment of Long-Lived Assets -- In accordance with SFAS No. 121
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," the Company continually evaluates whether events and
circumstances have occurred that indicate the remaining estimated useful life of
goodwill and/or other intangible assets may warrant revision or that all or a
portion of the remaining balance may not be recoverable.

     As a result of this evaluation process, during the fiscal year ended June
30, 1996, the Company wrote-down approximately $9,965,000 of costs relating to
client lists and related allocable goodwill obtained in the acquisition of MEDE
OHIO. Such intangible assets were written down to the net present value of the
estimated future cash flows to be derived from these clients as of June 30,
1996. The write-down was required due to a loss of approximately 25% of the
acquired MEDE OHIO client base.

     n. Income Taxes -- The Company accounts for income taxes under SFAS No.
109, "Accounting For Income Taxes," which requires recognition of deferred tax
assets and liabilities for the expected future tax consequences of events that
have been included in the Company's financial statements or tax returns. Under
this method, deferred tax assets and liabilities are determined based on the
differences between the financial accounting and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse.

     o. Use of Estimates in the Preparation of Financial Statements -- The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

     p. Unaudited Interim Financial Statements -- In the opinion of management,
the unaudited consolidated financial statements for the nine months ended March
31, 1998 and 1999 are presented on a basis consistent with the audited
consolidated financial statements and reflect all adjustments, consisting of
only normal recurring adjustments, necessary for a fair presentation of the
results thereof. The results of operations for interim periods are not
necessarily indicative of the results to be expected for the entire year.

     q. Comprehensive Income -- In 1999, the Company adopted SFAS No. 130,
"Reporting Comprehensive Income". This statement establishes rules for the
reporting of comprehensive income and its components. Comprehensive income, as
presented in the consolidated Statement of Stockholders' Equity (Deficit) is
equivalent to net income as the Company has no other items of comprehensive
income. The adoption of SFAS No. 130 had no impact on total shareholders'
equity.

     r. Reclassifications -- Certain amounts in prior years' financial
statements have been reclassified to conform with the 1998 presentation.

2. ACQUISITIONS

     a. EC&F and Premier -- In October 1995, the Company acquired all of the
outstanding shares of EC&F and Premier, which companies had common ownership,
for a cash purchase price of approximately $4,050,000, including transaction
expenses. The transaction was financed through loans obtained from the Company's
majority stockholder. Such loans were subsequently repaid with borrowings under
the Company's Credit Facility (as herein defined). In addition, the Company is
contingently liable for additional consideration if certain earnings levels are
attained relating to EC&F during the three-year period following the
consummation of the transaction. At June 30, 1996, the Company accrued $538,000
in connection with the contingent liability relating to earnings levels attained
during the first year. At June 30, 1997, the Company accrued a settlement
totaling $2,216,000 relating to the contingent liability for the second and
third years. Such accruals of contingent considerations were recorded as
compensation expense as these contingent payments were made to former
shareholders of EC&F and Premier who were required by the stock purchase
agreement to remain in the Company's employ during the period in which the
contingent consideration was to be earned. Purchased software and technology was
valued at $764,000 and generally is being amortized over three years. EC&F and
Premier are developers of electronic systems which provide EDI services to the
dental industry. In March 1997, the Company sold the operating net assets of
Premier for $540,000, including the buyer's assumption of $152,000 of Premier
liabilities. There was no gain or loss on the sale of such net assets.

     b. TCS -- In February 1997, the Company purchased certain assets of
Time-Share Computer Systems, Inc. ("TCS") for $11,465,000, including transaction
expenses. Purchased in-process research and development, which had not reached
technological feasibility and had no alternative future use amounted to
$1,556,000 and was charged to operations at the acquisition date. Purchased
software and technology was valued at $2,984,000 and generally is being
amortized over three years. TCS provides data processing and information
management services to healthcare providers and pharmacies through integrated
electronic data interchange systems. The acquisition was financed by a portion
of the proceeds from the Senior Subordinated Note and Share Purchase Agreement
(as hereinafter defined) (Note 6).

     c. Stockton -- In November 1997, the Company purchased certain assets and
assumed certain liabilities of The Stockton Group, Inc. ("Stockton") for a cash
purchase price of $10,674,000, including transaction expenses. In addition, the
Company is contingently liable for additional consideration of up to $2,600,000
(plus interest at an annual rate of 7.25%) if Stockton's revenue during the
12-month period ended September 30, 1998 is at least $5,000,000. Based on
revenues recorded through September 30, 1998 by Stockton, the Company has
accrued additional contingent consideration of $2,022,000 as of September 30,
1998, which was treated as additional purchase price and was, therefore, added
to goodwill. Purchased software and technology and client lists were valued at
$1,230,000 and $903,000, respectively, and generally are being amortized over
five years. Stockton is engaged in the business of providing EDI and transaction
processing services to the healthcare industry. The transaction was financed
through borrowings under the Company's Credit Facility.

     d. HII -- On October 30, 1998, the Company acquired all the outstanding
shares of capital stock of Healthcare Interchange, Inc. ("HII"), a St. Louis,
Missouri-based provider of EDI transaction processing services to hospitals and
physician groups in Missouri, Kansas and Illinois. Prior to the acquisition of
HII, two unrelated healthcare services divisions, Intercare and Telemedical,
were divested from HII in separate transactions. HII was purchased for a total
cash payment of approximately $11,718,000, including transaction expenses and
was financed with borrowings under the Credit Facility. Purchased client lists
were valued at $2,713,000 and are being amortized over five years.

     These acquisitions were recorded using the purchase method of accounting
and, accordingly, the results of operations of these acquired companies are
included in the consolidated results of operations of the Company since the
dates of their respective acquisitions. The purchase price of each acquisition

purchased software and technology.

- -------------------------
(a) On February 14, 1997, the Company entered into an agreement with an
    affiliate of certain shareholders of the Company under which the Company
    issued a $25,000,000 senior subordinated note (the "Senior Subordinated
    Note") and 370,993 shares of its common stock valued at $2,125,000
    (representing the estimated fair value of the common stock) for total
    consideration of $25,000,000 (the "Senior Subordinated Note and Share
    Purchase Agreement"). The $2,125,000 relating to the shares of common stock
    was recorded as a discount on the Senior Subordinated Note and was amortized
    over the term of the Senior Subordinated Note. The Senior Subordinated Note
    bore interest at the rate of 10% per annum, payable quarterly. One half of
    the principal sum was due on February 14, 2001, and the second half was due
    on February 14, 2002. The terms of the Senior Subordinated Note and Share
    Purchase Agreement placed restrictions on the consolidation, merger, or sale
    of the Company, indebtedness, and the payment of any cash dividends. The
    Senior Subordinated Note was repaid in February 1999 with a portion of the
    proceeds of the IPO. In connection with the repayment of the Senior
    Subordinated Note, the Company recorded an extraordinary charge of
    $1,619,000 relating to the write-off of the remaining discount on the Senior
    Subordinated Note.

(b) On January 26, 1999, the Company entered into a Credit Agreement (the "New
    Credit Facility") The New Credit Facility provides for a $25,000,000
    revolving credit facility that matures on January 26, 2002. Borrowings under
    the New Credit Facility bear interest at either the bank's base rate, as
    defined, plus .75 percent or an offshare rate, as defined, plus 1.75
    percent. The weighted average interest rate on outstanding borrowings at
    March 31, 1999 was 7.4 percent. The Company is required to pay a commitment
    fee of 0.5 percent per annum on the unused portion of the New Credit
    Facility. The New Credit Facility is not guaranteed by any third party, but
    is secured by substantially

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

    all of the Company's assets, including the stock of the Company's
    subsidiaries. The New Credit Facility contains various covenants and
    conditions, including those relating to Year 2000 compliance, changes in
    control and management and restrictions on the payments of dividends on the
    common stock [and requires the Company to maintain certain leverage and
    interest coverage rates and places restrictions on additional investments
    and indebtedness]. The closing of the New Credit Facility occurred
    simultaneously with the IPO.

    The New Credit Facility replaced the Company's existing revolving line of
    credit from a bank (the "Credit Facility") which was last amended on October
    7, 1998 to increase the maximum borrowings to $36,000,000. All borrowings
    under the Credit Facility were guaranteed by certain stockholders of the
    Company. In consideration for the granting of such guarantees, the
    stockholders were issued warrants to purchase 52,530 shares (valued at
    $121,000), 18,330 shares (valued at $52,000), 34,200 shares (valued at
    $98,000), and 84,050 shares (valued at $171,000) of the Company's common
    stock during the years ended June 30, 1996, 1997 and 1998 and the nine
    months ended March 31, 1999, respectively. All warrants issued were valued
    using the Black-Scholes Option Pricing Model. The aggregate fair value of
    these warrants was recorded in other assets as deferred financing costs and
    was amortized over the life of the agreement.

     Maturities of long-term debt as of June 30, 1998 are as follows:

1997 and 1998 consists entirely of current state income taxes.

     The provision for income taxes varies from the amount computed by applying
the statutory U.S. Federal income tax rate to the loss before provision for
income taxes as a result of the following:

</TABLE>

     The valuation allowance increased during the years ended June 30, 1997 and
1998 primarily as a result of additional net operating loss carryforwards and
net deductible temporary differences, for which realization was not considered
to be more likely than not. In the event that the tax benefits relating to the
valuation allowance are subsequently realized, approximately $5,600,000 of
benefits would reduce goodwill.

     As of June 30, 1998, the Company had Federal net operating loss
carryforwards of approximately $36,380,000. Such loss carryforwards expire in
the fiscal years 2005 through 2013. Because of the changes in ownership, as
defined in the Internal Revenue Code, which occurred during 1995 and 1996,
certain net operating loss carryforwards are subject to annual limitations.

8. STOCKHOLDERS' EQUITY

     a. Stock Option and Restricted Stock Purchase Plan -- In March 1995, the
Company established a stock option and restricted stock purchase plan (the
"Stock Plan"). The Stock Plan permits the granting of any or all of the
following types of awards: incentive stock options ("ISOs"); nonqualified stock
options ("NQSO"); or restricted stock. The Stock Plan authorizes the issuance of
655,000 shares of common stock. ISOs may not be granted at a price less than the
fair market value of the Company's common stock on the date of grant (or 110
percent of the fair market value in the case of persons holding ten percent or
more of the voting stock of the Company) and expire not more than ten years from
the date of grant (five years in the case of ISOs granted to persons holding ten
percent or more of the voting stock of the Company). The vesting period relating
to the ISOs is determined by the Option Committee of the Board of Directors at
the date of grant. The exercise price, expiration date, and vesting period
relating to NQSOs are determined by the Option Committee of the Board of
Directors at the date of grant.

     During March 1998, the Company granted 47,565 options at an exercise price
of $5.73 per share. The Company later determined that the value of the Company's
stock at the date of grant was $8.00. As a result, the Company recorded a
deferred compensation charge of $108,000 relating to the granting of these
options, of which $18,000 was amortized during the year ended June 30, 1998.
Effective August 31, 1998, the Company accelerated the vesting of these options
and, therefore, amortized the remaining balance.

     Significant option groups outstanding at June 30, 1998 and related weighted
average price and life information were as follows:

determined consistent with SFAS No. 123, "Accounting for Stock-Based
Compensation," the Company's net loss and net loss per share for the years ended
June 30, 1996, 1997 and 1998 would have been as follows:

     The weighted average fair value of the options granted for the years ended
June 30, 1996, 1997, and 1998 is estimated at $1.56, $1.83, and $1.92 on the
date of grant (using the minimum value option pricing model) with the following
weighted average assumptions for the years ended June 30, 1996, 1997, and 1998,
respectively: a risk-free interest rate of 5.93%, 6.39%, and 5.86%; an expected
option life of seven years and no expected volatility or dividend yield. As
required by SFAS No. 123, the impact of outstanding nonvested stock options
granted prior to July 1, 1995 has been excluded from the pro forma calculation;
accordingly, the 1996, 1997 and 1998 pro forma adjustments are not indicative of
future period pro forma adjustments when the calculation will apply to all
applicable stock options.

     b. Net income (loss) per share -- In 1997, the Company adopted SFAS No.
128, "Earnings Per Share." Basic income per share is determined by using the
weighted average number of shares of common stock outstanding during each
period. Diluted income per share further assumes the issuance of common shares
for all dilutive outstanding stock options and warrants as calculated using the
treasury stock method. Basic and diluted earnings per share are the same for all
of the periods presented because the effect of including outstanding options and
warrants would be antidilutive. The calculation for the years ended June 30,
1996, 1997 and 1998 and the nine months ended March 31, 1998 and 1999 was as
follows:

     c. Reverse Stock Split and Increase in Authorized Common Stock and
Preferred Stock -- On July 27, 1998, the Company amended and restated its
certificate of incorporation in order to, among other things, effect a reverse
stock split of all issued and outstanding common shares at the rate of 1 for
4.5823, which decreased the number of issued and outstanding shares as of June
30, 1998 from approximately 26,050,000 to approximately 5,685,000. This stock
split has been retroactively reflected in the accompanying financial statements
for all periods presented. The Company also increased the number of shares of
authorized common stock to 30,000,000 and the number of shares of authorized
preferred stock to 5,000,000, of which 250,000 were designated as relating to
Series A redeemable cumulative preferred stock (Note 9).

     d. Recapitalization -- In conjunction with the IPO and as provided for in
the Company's July 27, 1998 amendment and restatement of its certificate of
incorporation, the Company contemplates a recapitalization of its capital stock
(the "Recapitalization"). The Recapitalization involved the conversion of all
outstanding preferred stock into common stock (based upon liquidation value as
defined in Note 9) and the exercise of all outstanding warrants other than the
Medic Warrant (as herein defined) and warrants to purchase 84,050 shares of
common stock issued on October 7, 1998. (See Note 6.b.). The preferred stock
conversion was effected based upon the IPO price per share of $13.00 per share
and was converted into 1,845,815 shares of common stock. In addition, $301,000
of accrued dividends on the

preferred stock were converted into 23,124 shares of common stock. The warrants
were converted, in a cashless exercise, into 63,398 shares of common stock.

     e. Stock Purchase Plan -- In June, 1998, the Board has approved the 1998
Employee Stock Purchase Plan (the "Purchase Plan"). Employees of the Company,
including directors of the Company who are employees, are eligible to
participate in quarterly plan offerings in which payroll deductions may be used
to purchase shares of common stock. The purchase price of such shares is the
lower of 85 percent of the fair market value of the common stock on the day the
offering commences and 85 percent of the fair market value of the common stock
on the date the offering terminates. The first offering period under the
Purchase Plan commenced upon completion of the IPO.

     f. In June 1998, the Board approved the 1998 Stock Option and Restricted
Stock Purchase Plan (the "New Stock Plan"). The New Stock Plan permits the
granting of any or all of the following types of awards: incentive stock
options; nonqualified stock options; restricted stock; or other stock-based
awards, to officers, employees, directors, consultants and advisors of the
Company. The New Stock Plan authorizes the issuance of 1,500,000 shares of
common stock. Options to purchase an aggregate 400,000 shares of common stock
pursuant to the New Stock Plan were granted to certain employees of the Company
(including certain executive officers) upon consummation of the IPO. Such
options, which include both incentive and non-qualified stock options, have an
exercise price equal to the price to the public in the IPO and generally vest
ratably over four years from the date of grant except that the initial
installment of options granted to certain executive officers vested immediately
upon consummation of the IPO.

9. SERIES A REDEEMABLE CUMULATIVE PREFERRED STOCK

     As of June 30, 1998, the Company had outstanding 239,956 shares of
preferred stock. The preferred stock was subject to mandatory redemption in two
equal installments on May 31, 2001 and 2002; however, the Company was able to
redeem the preferred stock in whole at any time or in part from time to time at
its option. The redemption price, as well as liquidation value, of the preferred
stock was $100 per share plus any accrued but unpaid dividends. Dividends on
this preferred stock, which were cumulative, were payable, if declared, at $10
per share per annum. All shares of preferred stock were converted into common
stock in connection with the Recapitalization and $301,000 of accrued dividends
on the preferred stock were converted into 63,398 shares of common stock. The
remaining accrued dividends were paid with a portion of the net proceeds of the
IPO (see Note 8.d.).

     d. Defined Contribution Plans -- The Company maintained four defined
contribution plans (the "Plans") for all eligible employees, as defined by the
Plans until April 1, 1996. On April 1, 1996, the Company combined the Plans into
one defined contribution plan (the "New Plan"). The Company previously made
matching contributions at various percentages to three of the Plans in
accordance with the respective Plan documents and currently makes matching
contributions to the New Plan in an amount equal to fifty percent of the
employee salary deductions to a maximum of four percent of the employees salary
in accordance with the New Plan document. The Company incurred $197,000,
$227,000, and $194,000 for employer contributions to the Plans/New Plan for the
years ended June 30, 1996, 1997 and 1998, respectively.

     e. Service Agreements -- The Company has entered into service agreements
with telecommunications providers which require the Company to utilize certain
minimum levels of the services of such providers. These agreements expire

11. TRANSACTION PROCESSING AGREEMENT

     On July 17, 1998, the Company entered into a transaction processing
agreement (the "Processing Agreement") with Medic Computer Systems, Inc.
("Medic"), a subsidiary of Misys plc that develops and licenses software for
healthcare providers, principally physicians, MSOs and PPMs. Under the
Processing Agreement, the Company will undertake certain software development
obligations, and on July 1, 1999 it will become the exclusive processor (subject
to certain exceptions) of medical reimbursement claims for Medic's subscribers
submitted to payors with whom MedE has or establishes connectivity. Under the
Processing Agreement, the Company will be entitled to revenues to be paid by
payors (in respect of which a commission is payable to Medic) as well as fees to
be paid by Medic. The Processing Agreement sets forth detailed performance
criteria and development and implementation timetables. Inability to meet these
criteria may result in financial penalties or give Medic a right to terminate
this agreement. The Processing Agreement is for a fixed term of five years, with
annual renewals thereafter (unless either party elects to terminate).

<PAGE>   332
                   MEDE AMERICA CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     Contemporaneously, to ensure a close working relationship between the
parties, on July 17, 1998 the Company granted to Medic a warrant (the "Medic
Warrant") to acquire 1,250,000 shares of the Company's common stock, at a per
share exercise price equal to the price of the common stock to the public in the
IPO or, in the event that the IPO is not completed by March 31, 1999 at an
exercise price equal to $8 per share. The Medic Warrant vests over a two year
period and may be exercised up to five years after issuance. The Medic Warrant
was valued at $3,925,000 using the Black-Scholes Option Pricing Model and is
recorded in other assets. The Medic Warrant is being amortized over the life of
the Processing Agreement, five years. The Medic Warrant contains customary
weighted average antidilution provisions. The Company and certain principal
stockholders have agreed that following the completion of the IPO and until the
earlier of the termination of the Processing Agreement or the disposition by
Medic and its affiliates of at least 25% of the shares of common stock issuable
under the Medic Warrant, Medic shall have the right to designate one director to
the Company's Board of Directors.

12. OTHER INCOME

     In February 1997, the Company exercised 26,712 options to purchase common
shares of First Data Corporation and subsequently sold the common shares
resulting in a pre-tax gain of $885,000. Such options were issued to former
employees of the Company prior to the Spin-off but reverted to the Company upon
the termination of these employees.

13. RESTATEMENT

     Subsequent to the issuance of the Company's consolidated financial
statements for the fiscal year ended 1998, the Company's management determined
that it was necessary to revise the valuation of the write-off of in-process
research and development incurred in connection with the TCS acquisition in
February 1997. As a result, the Company's financial statements for the fiscal
years ended June 30, 1997 and 1998 have been restated from the amounts
previously reported in order to reflect the effects of the adjustment to the
write-off of in-process research and development. Such write-off, which occurred
during the year ended June 30, 1997, was reduced from $4,354,000 to $1,556,000.
As a result, goodwill was increased by $2,798,000. The effect of the restatement
is as follows:

14. SUBSEQUENT EVENTS (UNAUDITED)

     On April 20, 1999, the Company, Healtheon Corporation ("Healtheon") and
Merc Acquisition Corp., a wholly-owned subsidiary of Healtheon ("Merger Sub")
entered into an Agreement and Plan of Reorganization (the "Merger Agreement"),
pursuant to which Merger Sub will be merged with and into the Company, with the
Company being the surviving corporation of such merger (the "Merger"). Upon

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

consummation of the Merger, the separate existence of Merger Sub will cease, and
the existing stockholders of the Company will become stockholders of Healtheon
in accordance with the terms of the Merger Agreement.

     The consideration for the Merger will consist of newly-issued shares of
Healtheon common stock, par value $.0001 per share ("Healtheon Common Stock"),
having an aggregate value of approximately $460 million, based upon the closing
sales price of $45.69 per share for the Healtheon Common Stock as reported on
Nasdaq on April 20, 1999. At the effective time of the Merger, each outstanding
share of common stock, par value $.01 per share, of the Company ("Company Common
Stock") will be converted into the right to receive 0.6593 shares of Healtheon
Common Stock (the "Exchange Ratio"), subject to adjustment as described below.

     In the event that the 10 day average closing price for Healtheon Common
Stock for the periods ending July 30, 1999 (the "July 30 Price") and two days
prior to the date the Company's shareholders meet to authorize the merger (the
"Meeting Price"), is greater than $63.70 per share, the Company has the option
to adjust the Exchange Ratio to a ratio equal to $42 divided by the lower of the
July 30 Prices or the Meeting Price or, if the Company chooses not to exercise
such option, Healtheon can terminate the Merger Agreement. In the event that
either the July 30 Price or the Meeting Price is less than $38.68 per share,
Healtheon has the right to adjust the Exchange Ratio to a ratio equal to $25.50
divided by the applicable price or, if the Healtheon chooses not to exercise
such option, the Company can terminate the Merger Agreement.

     The consummation of the Merger is subject to certain conditions, including,
among other things, approval by the stockholders of the Company and the receipt
of all necessary regulatory approvals pursuant to the Hart-Scott-Rodino
Antitrust Improvement Act of 1976, as amended. Pursuant to the Merger Agreement,
Healtheon and the Company will prepare and file a proxy statement/prospectus to
be mailed to stockholders in connection with calling a meeting of the
stockholders of the Company to vote on the Merger.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of
Direct Medical Knowledge, Inc.

     In our opinion, the accompanying balance sheets and the related statements
of operations and retained earnings and of cash flows present fairly, in all
material respects, the financial position of Direct Medical Knowledge, Inc., a
development stage company (the Company), at December 31, 1998 and 1997, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1998, and for the period from May 24, 1995 (date of
incorporation) to December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

     The financial statements of the Company for the period from May 24, 1995
(date of incorporation) to December 31, 1996 were audited by other auditors,
whose reports expressed an unqualified opinion on those statements. Our opinion,
in so far as it relates to the amounts included for the period from May 24, 1995
(date of incorporation) to December 31, 1996, is based solely on the reports of
the other auditors.

     The accompanying financial statements have been prepared assuming that the
company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has sustained recurring losses and negative
cash flows from operations that raise substantial doubt about its ability to
continue as a going concern. Management's plans in regard to these matters are
also described in Note 1. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

     As discussed in Note 1 (J) and Note 3, the Company previously recorded net
deferred tax assets due to net operating loss carryforwards from 1996 and 1995.
The Company has restated these financial statements to record a retroactive
valuation allowance against its net deferred tax assets. Additionally, the
Company is determined to be a development stage company. To reflect this change
in classification, the financial statements have been restated in accordance
with disclosure requirements for development stage companies.

1. COMPANY BACKGROUND

Description of business:

     Direct Medical Knowledge, Inc. ("the Company") was incorporated on May 24,
1995 to provide individualized, customized medical and health information to
individuals through contracts with major health providers. The Company uses web
technology, electronic retrieval, and on-line support groups to deliver health
information over the internet. Since its incorporation, the Company has focused
on developing its products and marketing strategy and recruiting human
resources. It has not generated a significant amount of revenue and,
accordingly, is a development stage company.

Need for additional capital and sale of the company

     The Company's financial statements have been prepared assuming that the
Company will continue as a going concern. The Company has sustained recurring
losses and negative cash flows from operations. The Company's continued
existence is dependent upon its ability to increase operating revenues and/or
raise additional equity financing. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

     In January 1999, the shareholders approved the merger of the Company with a
wholly-owned subsidiary of WebMD, Inc. ("WebMD"). WebMD provides administrative,
communications and information services to healthcare professionals via the
internet, as well as healthcare information services to consumers. Under the
terms of the merger agreement, shares of the Company's capital stock will be
exchanged for 469,018 shares of WebMD Series B Preferred Stock as set forth
below. Outstanding options and warrants to purchase the Company's common stock
will be assumed by WebMD and will be subject to the same terms and conditions,
with the exception that they will be exercisable for 130,957 shares of WebMD
Series B Preferred Stock based upon the exchange ratio set forth below for the
Company's common stock. The $500 Convertible Promissory Note outstanding as of
the date of the merger will be exchanged for 25,000 shares of WebMD Series B
Preferred Stock.

     The ratios for the exchange of the Company's capital stock for shares of
WebMD Series B Preferred Stock are as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Business risks and credit concentrations

     The Company operates in the internet content industry segment which is new,
rapidly evolving and highly competitive. The Company relies on third party
suppliers of health information content. There can be no assurance that the
Company will be able to continue product development and secure content
sufficient to support its operations.

     The Company performs ongoing credit evaluations of its customers' financial
condition. It generally requires no collateral and maintains reserves for
potential credit losses on customer accounts, when necessary. Management
estimates that no such reserves are warranted at December 31, 1998 or December
31, 1997. At December 31, 1998, one shareholder comprises 38% of accounts
receivable and, with one other customer, accounted for 100% of revenue for the
year then ended.

     The same two customers accounted for 100% of revenue for the year ended
December 31, 1997 and 1996, while the shareholder and two other customers
accounted for 100% of revenue for the period from May 24, 1995 (date of
incorporation) to December 31, 1998.

Cash and cash equivalents

     The Company considers all highly liquid monetary instruments with an
original maturity of three months or less to be cash equivalents. Substantially
all of the Company's cash is held at one major financial institution.

Content license fees

     License fees for website content are capitalized and amortized over the
life of the license. During 1997, most license agreements covered one year
periods with the option to renew annually. During 1998, the Company began
transitioning to two to five year agreements. Accumulated content license fee
amortization totaled $72 and $113, at December 31, 1998 and 1997, respectively.

Property and equipment

     Property and equipment are stated at cost. Maintenance and repairs are
charged to operations as incurred. Depreciation and amortization are determined
on the straight-line method over the estimated useful lives of the related
assets, which range from three to five years. When assets are retired or
otherwise disposed of, the cost and accumulated depreciation and amortization
are removed from the accounts, and any resulting gain or loss is reflected in
operations in the period realized.

Impairment of long-lived assets

     Statement of Financial Accounting Standards No. 121 (SFAS No. 121),
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of, requires that long-lived assets and certain intangible assets be
reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount may not be recoverable. If undiscounted expected future
cash flows are less than the carrying value of the assets, an impairment loss is
to be recognized based on the fair value of the assets. The Company considers
the requirements of SFAS No. 121 on an ongoing basis. During 1998, losses of
$121 were recognized on obsolete website equipment and software to be disposed
of and were accounted for under general and administrative expenses. No
impairment losses were recognized in prior periods.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Revenue recognition

     Revenue from report orders is recognized upon delivery of the corresponding
report. Support services, including revenue from marketing and distribution
agreements with ongoing support requirements, are recognized ratably over the
life of the contract. Revenue from website development is recognized using the
percentage-of-completion method. Amounts billed in excess of revenue earned and
advance payments are deferred and recorded as revenues when earned.

Content development

     The Company expenses content development costs as incurred.

Income taxes

     In accordance with Statement of Financial Accounting Standards No. 109
(SFAS No. 109), Accounting for Income Taxes, deferred income taxes are
recognized for the differences between the tax basis of assets and liabilities
and their financial reporting amounts based on enacted tax laws and statutory
tax rates applicable to the periods in which the differences are expected to
affect taxable income. A valuation allowance is recognized for deferred tax
assets when it is more likely than not that some portion or all of the deferred
tax asset will not be realized. Income tax expense is comprised of tax payable
or refundable for the current period plus the change during the period in
deferred tax assets and liabilities.

Recently issued accounting pronouncements

     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 provides guidance
for determining whether computer software is internal-use software and on
accounting for the proceeds of computer software originally developed or
obtained for internal use and then subsequently sold to the public. It also
provides guidance on capitalization of the costs incurred for computer software
developed or obtained for internal use. The Company has not yet determined the
impact of adopting SOP 98-1, which will be effective for the Company's year
ending December 31, 1999.

     On April 3, 1998, the Accounting Standards Executive Committee issued
Statement of Position 98-5, (SOP 98-5) Reporting on the Costs of Start-Up
Activities, which provides guidance on the financial reporting of start-up costs
and organization costs. It requires costs of start-up activities and
organization costs to be expensed as incurred. SOP 98-5 is effective for
financial statements for fiscal years beginning after December 15, 1998. As the
Company has not capitalized such costs to date, the adoption of SOP 98-5 is not
expected to have an impact on the financial statements of the Company.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     As of December 31, 1998, the Company has net operating loss carryforwards
of approximately $5,160 for federal income tax purposes. These carryforwards
expire in years 2010 through 2018. In addition, the Company has carryforwards of
approximately $5,156 as of December 31, 1998 for California franchise tax
purposes, expiring in 2003.

     As a result of changes in the Company's ownership, the amount of loss
carryforwards available to offset future federal and state taxable income may be
limited by IRS Code Section 382 pursuant to the Tax Reform Act of 1986. The
amount of such limitation, if any, has not been determined.

     A reconciliation of the provision for income taxes to the federal statutory
rate is as follows:

6. SENIOR SECURED PROMISSORY NOTE

     In February 1998, the Company obtained a one million dollar credit facility
to finance equipment purchases through December 31, 1998. Borrowings under this
facility are executed as 36 month promissory notes collateralized by the
purchased equipment. Interest accrues at an effective rate of 18% per annum.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

7. NOTE AND WARRANT PURCHASE AGREEMENT

     In September 1998, the Company entered into a Note and Warrant Purchase
Agreement, (the "Agreement") with a shareholder, whereby the Company may borrow
up to a maximum of $500 under Convertible Promissory Notes (the "Notes"). Each
of the Notes is non-interest bearing, has a term of six months and, in the event
the Company issues shares of its Preferred Stock during the term of the Notes,
is convertible into that Preferred Stock at a conversion price equal to the
price per share paid by investors purchasing the preferred stock. Warrants to
purchase common stock of the Company are attached to each of the Notes. Each of
the Warrants allows the holder to purchase one share of common stock for each
dollar borrowed at an exercise price of $0.25 per share and is exercisable for a
period of five years. As of December 31, 1998, the Company had borrowed $500 and
issued warrants to purchase 500,000 shares of common stock under the Agreement.
The fair value of the warrants of $34 was included in the statement of
operations as interest expense, and was determined using a Black-Scholes model
applying a risk-free interest-rate of 5.05%, and a zero percent dividend yield.
Because the Company does not have actively traded equity securities, volatility
is not considered in determining the fair value of these warrants.

8. CONVERTIBLE PREFERRED STOCK

     The Company is authorized to issue up to 2,600,000 shares of no par
preferred stock in one or more series. The Company has designated 1,100,000 of
the preferred shares as Series A and 1,500,000 as Series B.

     Series A and Series B preferred shareholders are entitled to receive, when
and if declared by the Board of Directors, out of funds legally available, a
preferential, noncumulative annual cash dividend of $0.08 per share and $0.16
per share, respectively. Preferred shareholders are also entitled to participate
in cash dividends paid to common shareholders in an amount per share as would be
payable on the number of whole shares of common stock into which the preferred
shares could be converted. So long as any preferred shares are outstanding, no
cash or property dividends may be declared or paid on common stock until all
preferred stock dividends have been paid or declared and set apart. Through
December 31, 1998, $98 in Series A dividends have been declared, and 97,658
shares of Series A preferred stock have been issued in lieu of cash dividends.
Concurrent with the issuance of Series B preferred stock, the Company's Articles
of Incorporation were amended to eliminate mandatory dividend provisions on
Series A preferred stock.

     Preferred shareholders are entitled to vote together with the holders of
common stock. The number of votes equals the number of whole shares of common
stock into which each holder's preferred shares could be converted. So long as
at least 100,000 shares of Series A remain outstanding, Series A shareholders
are collectively entitled to elect one director. So long as at least 100,000
shares of Series B remain outstanding, Series B shareholders are collectively
entitled to elect one director. Common shareholders are also collectively
entitled to elect one director. All shareholders are collectively entitled to
elect the remaining directors. Certain transactions which could affect the
relative rights and privileges of preferred shareholders, as defined in the
Articles of Incorporation, require majority approval by Series A shareholders
and 60% approval by Series B shareholders, respectively. Certain other
transactions require approval by not less than two-thirds of Series A
shareholders.

     At the option of the shareholder, preferred shares are convertible into
common stock at any time on a one-for-one basis, subject to certain adjustments.
Series A and Series B preferred shares are automatically converted into common
stock on a one-for-one basis, subject to certain adjustments, in the event of a
public offering with gross proceeds of at least $15 million and a per share
price of at least $7, subject to certain adjustments, or upon the consent by 50%
of Series A shareholders or by 60% of Series B

shareholders, respectively for each series. Any declared and unpaid dividends
must be paid upon automatic conversion. The Company has reserved sufficient
common shares for conversion.

     In the event of any liquidation, dissolution or winding up of the Company,
preferred shareholders are entitled to receive an amount equal to $1.00 per
share of Series A and $2.05 per share of Series B plus all declared and unpaid
dividends on a pari passu basis prior and in preference to any distributions to
common shareholders. After payment has been made to the preferred shareholders,
any remaining assets will be distributed ratably to all shareholders in
proportion to the amount of stock owned by each shareholder. If the Company's
assets are insufficient to provide for the full preference amount for the
preferred stock outstanding, then such assets will be distributed ratably among
preferred shareholders in proportion to the amount of such stock owned by each
preferred shareholder.

9. STOCK OPTION PLAN

     The Company has a Stock Option Plan (the "Plan") under which the Board of
Directors may grant common stock options to employees, directors and
consultants. Under the Plan, options generally vest 20% one year from the
vesting commencement with an additional 2% vesting each month thereafter. A
total of 750,000 shares of the Company's common stock have been reserved for
issuance under the Plan. Shares sold under the Plan are subject to various
restrictions as to resale and right of repurchase by the Company.

     Options under the Plan may be either "incentive stock options" or
"nonqualified stock options" as defined under Section 422 of the Internal
Revenue Code. Options shall be exercisable within the periods or upon the events
determined by the Board of Directors or a committee appointed by the Board of
Directors as set forth by a written stock option grant, provided however, that
no option shall become exercisable after the expiration of 10 years from the
date the option is granted. Additionally, no option granted to a person who
directly or by attribution owns more than 10% of the total combined voting power
of all classes of stock of the Company shall be exercisable after the expiration
of five years from the date the option is granted. Vested options held by
individuals upon termination of their relationship with the Company may be
exercised no later than three months following the date of termination or twelve
months following death or disability until expiration of the option.

     The following table summarizes activity under the Company's stock option
plan for the years ended December 31, 1998 and 1997. There was no activity under
the Plan in prior periods.

     The Company has elected to follow Accounting Principles board Opinion No.
25 (APB No. 25), Accounting for Stock Options Issued to Employees and related
interpretations in accounting for its employee stock options. Under APB No. 25,
compensation expense is recognized based on the amount by which the fair value
of the underlying common stock exceeds the exercise price of the stock options
at the measurement date, which in the case of employee stock options is
typically the date of grant.

     SFAS No. 123, Accounting for Stock-Based Compensation, encourages adoption
of a fair value-based method for valuing the cost of stock-based compensation.
However, it allows companies to continue to use the intrinsic value method under
APB No. 25 for options granted to employees and to disclose pro forma net
earnings and earnings per share in accordance with SFAS No. 123. Had
compensation cost for the Company's stock-based compensation plans been
determined consistent with SFAS No. 123, the Company's net earnings would have
been as follows:

     The weighted average fair value of stock options granted during 1998 and
1997 was $0.11 and $0.048, respectively.

     The effects of applying SFAS No. 123 for the pro forma disclosures are not
representative of the effects expected on reported net earnings and earnings per
share in future years, since valuations are based on highly subjective
assumptions about the future, including stock price volatility and exercise
patterns.

     The Company used the Black-Scholes option pricing model to determine the
fair value of grants made in 1998 and 1997. The following assumptions were
applied in determining the pro forma compensation cost:

</TABLE>

     Because the Company does not have actively traded equity securities,
volatility is not considered in determining the fair value of stock-based awards
to employees.

10. SUBSEQUENT EVENTS

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Sapient Health Network, Inc.:

     We have audited the accompanying balance sheets of Sapient Health Network,
Inc. (the Company) as of September 30, 1997 and 1998, and the related statements
of operations, shareholders' deficit, and cash flows for the period from
November 21, 1995 (date of inception) through September 30, 1996 and each of the
years in the two-year period ended September 30, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Sapient Health Network, Inc.
as of September 30, 1997 and 1998, and the results of its operations and its
cash flows for the period from November 21, 1995 (date of inception) through
September 30, 1996 and each of the years in the two-year period ended September
30, 1998 in conformity with generally accepted accounting principles.

     The accompanying financial statements have been prepared assuming that
Sapient Health Network, Inc. will continue as a going concern. As discussed in
note 2 to the financial statements, the Company has incurred losses since
inception and has a net capital deficiency; these conditions raise substantial
doubt about the Company's ability to continue as a going concern. Management's
plans in regard to these matters are also described in note 2 to the financial
statements. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

Unaudited Quarterly Information

     The financial information included herein for the three-month periods ended
December 31, 1997 and 1998 is unaudited; however, such information reflects all
adjustments consisting only of normal recurring adjustments which are, in the
opinion of management, necessary for a fair presentation of the financial
position, results of operations and cash flows for the interim periods. The
interim consolidated financial statements should be read in conjunction with the
financial statements and the notes included in the financial statements. The
results of operations for the interim period presented are not necessarily
indicative of the results to be expected for the full year.

Revenue Recognition

     Revenue from market research contracts is recognized upon delivery and
acceptance of the product by the customer. The amount of revenue for specific
projects is determined by market pricing models or associated direct costs of
the delivered and accepted product.

     Revenue from sponsorship contracts for Web development and related
activities, which includes banner advertising, development of the interview
profile, and reporting of data and site activity, is recognized in time
milestones, usually prorated over the length of the agreement. Revenue from
additional specified projects within the sponsorship contract is determined by
precedent pricing models or associated direct costs of the project, and
recognized when delivered and accepted by the customer. These additional
projects could consist of clinical trial recruitments and additional focus group
interviews as well as other customer specific requests.

     Deferred revenue and unbilled revenue represent amounts to be recognized
and billed upon project completion or upon achievement of project milestones.
Contracts may have termination and refund provisions that require payment for
all work completed through date of termination notice. Contracts may have
nonrefundable fees due upon signing associated with upfront set up costs that
are not related to project milestones or product deliverables. These fees are
recognized upon signing.

     All of the Company's revenues for the years ended September 30, 1997 and
1998 were from sales in the U.S.

                       AND DECEMBER 31, 1998 (UNAUDITED)

Property and Equipment

     Property and equipment are stated at cost. Depreciation of property and
equipment is calculated on the straight-line method over the estimated useful
life of the assets, generally three years. Property and equipment held under
capital leases and leasehold improvements are amortized based on the
straight-line method over the shorter of the lease term or estimated useful life
of the assets, generally three years.

     Maintenance and repairs are charged to expense as incurred. Major repairs
and improvements are capitalized and depreciated.

Restricted Investment

     The Company has a certificate of deposit held by a bank as collateral for a
$200,000 standby letter of credit for costs incurred by the landlord, for the
Company's office space remodeling.

Other Assets

     Other assets consist primarily of patents and legal costs to obtain
financing. Patents are amortized using the straight-line method over the
estimated future economic benefit, which is generally three years. Financing
costs are amortized over the life of the loan unless conversion is expected
within a twelve month period, in which case they are netted against the proceeds
upon conversion. Amortization expense for the period from November 21, 1995
(date of inception) through September 30, 1996 and the years ended September 30,
1997 and 1998 was $3,029, $8,036 and $10,949, respectively. Accumulated
amortization at September 30, 1997 and 1998 was $11,065 and $22,014,
respectively.

Research and Development Expenditures

     The Company incurs research and development expenses relating to the
development of its product. All research and development costs are expensed as
incurred.

Capitalized Software

     Under Statement of Financial Accounting Standards No. 86, software
development costs are to be capitalized beginning when a product's technological
feasibility has been established and ending when a product is made available for
general release to customers. The establishment of technological feasibility of
the Company's products has occurred shortly before general release and,
accordingly, no costs have been capitalized.

Management Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities.
Estimates and assumptions are also used in the disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

Income Taxes

     The Company accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
financial statement carrying amounts of existing assets and liabilities

                                      F-92

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                          SEPTEMBER 30, 1997 AND 1998
                       AND DECEMBER 31, 1998 (UNAUDITED)

and their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date. Valuation
allowances are established to reduce deferred tax assets to the amount expected
to be realized.

Stock-Based Compensation

     The Company accounts for stock-based compensation using Statement of
Financial Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based
Compensation. This statement permits a company to choose either a fair-value
based method of accounting for its stock-based compensation arrangements or to
comply with the current Accounting Principles Board Opinion 25 (APB Opinion 25)
intrinsic-value-based method adding pro-forma disclosures of net loss computed
as if the fair-value-based method had been applied in the financial statements.
The Company applies SFAS No. 123 by retaining the APB Opinion 25 method of
accounting for stock-based compensation for employees with annual pro-forma
disclosures of net loss. Stock-based compensation for non-employees is accounted
for using the fair-value-based method.

Net Loss Per Share

     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings Per Share ("SFAS No. 128"). SFAS No. 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share. Unlike primary and fully diluted earnings per share, outstanding
nonvested shares are not included in the computations of basic and diluted
earnings per share until the time-based vesting restriction has lapsed. Basic
earnings per share also excludes any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share.

Fair Value of Financial Instruments

     The Company's financial instruments consist of cash, accounts receivable,
accounts payable, capital leases, convertible promissory notes and the line of
credit. At September 30, 1997 and 1998, the fair value of the Company's
receivables, payables, line of credit, capital lease obligations and convertible
promissory notes approximated fair value.

Advertising

     The Company expenses the costs of advertising when the costs are incurred.
Advertising expense was approximately $2,000, $229,000 and $519,000 for the
period from November 21, 1995 (date of inception) through September 30, 1996 and
the years ended September 30, 1997 and 1998, respectively.

Reclassifications

     Certain amounts for 1996 and 1997 have been reclassified to conform to the
presentation for 1998. Such reclassifications have no effect on previously
reported results of operations.

Effect of Recent Accounting Pronouncements

     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, Reporting Comprehensive Income, which establishes requirements for
disclosure of comprehensive income. The

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                          SEPTEMBER 30, 1997 AND 1998
                       AND DECEMBER 31, 1998 (UNAUDITED)

objective of SFAS 130 is to report all changes in equity that result from
transactions and economic events other than transactions with owners.
Comprehensive income is the total of net income and all other non-owner changes
in equity. SFAS 130 is effective for fiscal years beginning after December 15,
1997. Reclassification of earlier financial statements for comparative purposes
is required. The Company does not expect implementation to have a significant
impact on its financial statements.

     Also in June 1997, the FASB issued SFAS No. 131, Disclosure about Segments
of an Enterprise and Related Information. SFAS 131 requires public companies to
report certain information about their operating segments in a complete set of
financial statements to shareholders. It also requires reporting of certain
enterprise-wide information about the company's products and services, its
activities in different geographic areas and its reliance on major customers.
The basis for determining the company's operating segments is the manner in
which management operates the business. SFAS 131, is effective for fiscal years
beginning after December 15, 1997. The Company does not expect implementation to
have a significant impact on its financial statements.

     In October 1997, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 97-2, Software Revenue
Recognition,which provides guidance on applying generally accepted accounting
principles in recognizing revenue of software transactions. The Company adopted
SOP 97-2 on January 1, 1998. The impact to the Company's financial statements
was not material.

     Related to the SOP 97-2, the AICPA issued SOP 98-4 Deferral of the
Effective Date of a Provision of SOP 97-2, Software Revenue Recognition. SOP
98-4 defers for the one year, the application of several paragraphs and examples
in SOP 97-2 that limit the definition of vendor specific objective evidence of
the fair value of various elements in a multiple element arrangement. The impact
on the Company's financial statements is not expected to be material.

     In April 1998, the AICPA Accounting Standards Executive Committee issued
Statement of Position (SOP) 98-5, Reporting on the Costs of Start-Up Activities.
The SOP requires that costs incurred during start-up activities, including
organizational costs, be expensed as incurred. SOP 98-5 is effective for
financial statements for fiscal years beginning after December 15, 1998.
Restatement of previously issued financial statements is not permitted. The
Company does not expect implementation to have a significant impact on its
financial statements.

     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability at its fair value. The
standard also requires that changes in the derivatives' fair value be recognized
currently in the results of operations unless specific hedge accounting criteria
are met. SFAS 133 is effective for fiscal years beginning after June 15, 1999.
The Company does not expect SFAS 133 to have a material impact on its financial
statements.

(2) LIQUIDITY

     To meet the cash flow needs of the Company in fiscal 1999, the Company will
need to issue additional equity securities, borrow additional funds, or obtain
other financing. The Company has no commitments for additional financing and
there can be no assurance that such financing will be available on satisfactory
terms, if at all. The accompanying financial statements have been prepared on
the basis that the Company will be able to meet its cash needs and continue as a
going concern. See note 15.

</TABLE>

     The valuation allowance for deferred tax assets as of September 30, 1997
and 1998, was $2,222,800 and $3,992,700, respectively. The net change in the
total valuation allowance for the period November 21, 1995 (date of inception)
through September 30, 1996 and the years ended September 30, 1997 and 1998, was
an increase of $450,000, $1,772,800 and $1,769,900, respectively.

     At September 30, 1998, the Company has net operating loss carryforwards of
approximately $9,526,000 and research and experimentation credit carryforwards
of $87,800 to offset future federal taxable income and income taxes, if any,
through 2017. As defined in Internal Revenue Section 382, the utilization of a
portion of the net operating loss and credit carryforwards may be limited due to
a change in ownership caused by additional investors, occurring on November 1,
1996. The Company believes no additional ownership changes have occurred,
however a formal analysis has not been completed.

(8) STOCK OPTION PLAN

     Effective January 30, 1996, the Company adopted a Stock Option Plan (the
Plan) which provides for the granting of stock options to employees, directors
and consultants within the meaning of Section 442 of the Internal Revenue Code,
and non-statutory stock options. The right to exercise these options vests from
zero to forty-eight months. The Company has reserved 1,500,000 shares of common
stock for issuance upon exercise of options granted under the Plan.

     As of September 30, 1998, 1,097,409 options remain outstanding pursuant to
the Plan. The per share weighted-average fair value of stock options granted
during the period from November 21, 1995 (date of inception) through September
30, 1996 and the years ended 1997 and 1998 were $.10, $.16 and $.27,

be amortized on a straight-line basis over the vesting period of the options
(typically four years).

     The Company applies Accounting Principle Bulletin Opinion No. 25 in
accounting for stock options issued to employees and directors under the Plan,
accordingly, no compensation cost has been recognized for these stock options in
the financial statements. Had the Company determined compensation cost based on
the fair value at the grant date for its stock options under Statement of
Financial Accounting Standards (SFAS) No. 123 the Company's net loss would have
been increased to the pro forma amounts indicated below:

(9) REDEEMABLE PREFERRED STOCK AND SHAREHOLDERS' DEFICIT

Preferred Stock

     The Company is authorized to issue up to 10,000,000 shares of preferred
stock. During fiscal 1998, the Company amended its articles of incorporation to
designate a new series of preferred stock, designated as Series C preferred
stock, and to amend certain terms of the rights, privileges and preferences of
its Series B preferred stock. Following such amendment, the Company had three
series of convertible preferred stock, designated as Series A, B and C preferred
stock. The Company's Series B and C preferred stock is redeemable as described
more fully below. The material rights, preferences, privileges and restrictions
for each series of preferred stock are summarized below:

Dividends

     Holders of the Series B and C preferred stock shall be entitled to receive
cumulative dividends of eight percent (8%) of the original issue per share price
of each such series per share per annum prior and in preference to the holders
of any other stock of the Company. Such cumulative dividends shall cease to
accrue when the balance of such cumulative dividends, whether paid or unpaid,
equals, in the aggregate, two times the respective original issue price of the
Series B and C preferred stock. The holders of the Series B and C preferred
stock are also entitled to receive an amount equal per share to any dividend
declared and paid to holders of the Company's common stock. The holders of the
Series A preferred stock

                       AND DECEMBER 31, 1998 (UNAUDITED)

are entitled to receive an amount equal per share to any dividend declared and
paid to holders of the Company's common stock.

Liquidation Preferences

     Upon the occurrence of a liquidation event, such as a dissolution of the
Company or a merger or sale of assets, the holders of Series C preferred stock
shall be entitled to receive in preference to holders of Series A and B
preferred stock and common stock an amount equal to the proportion that the
Series C preferred stock represents to the fully diluted capital stock of the
Company, the holders of Series B preferred stock shall be entitled to receive in
preference to holders of Series A preferred stock and common stock an amount
equal to the original issue price of the Series B preferred stock, the holders
of Series A preferred stock shall be entitled to receive in preference to
holders of common stock an amount equal to up to the original issue price of the
Series A preferred stock, the holders of Series B preferred stock shall be
entitled to then receive in preference to the holders of common stock up to an
amount equal to two times the original issue price of the Series B preferred
stock, and thereafter, the holders of Series A, B and C preferred stock shall
share any remaining proceeds on a pro rata basis with the holders of common
stock based on the number of shares of common stock held by each, assuming full
conversion of the Series A, B and C preferred stock.

Conversion

     Holders of the Series A, B and C preferred stock may convert all or part of
their shares at any time after the date of issuance into such number of common
stock as is determined by multiplying such number of shares by the series
conversion rate in effect at the time. Conversion is automatic upon the closing
of an IPO of the Company's common stock at a price of not less than $6.16 per
share and with aggregate gross proceeds of not less than $20,000,000 or by
written consent or agreement of the holders of two-thirds of the outstanding
shares of Series A, B and C preferred stock voting together as a single class.

Redemption

     The Company shall redeem the Series B and C preferred stock at the option
of the holders of such preferred stock after September 30, 2001 and before
September 30, 2004, subject to reasonable financial stability considerations,
payable in eight equal quarterly installments. The holders of the Series B and C
preferred stock shall be entitled to a redemption price per share equal to the
original issuance price, plus accrued and unpaid dividends with respect to such
shares.

Common Stock

     The Company is authorized to issue up to 15,000,000 shares of common stock.
The common stock shareholders have voting rights and, subject to any
preferential rights granted to any series of preferred shareholders, are
entitled to receive distributions legally payable to shareholders upon
liquidation of the Company.

Warrants

     During fiscal 1997, the Company issued warrants to investors. Each warrant
permits the holder to purchase one share of the Company's common stock. At
September 30, 1998 warrants to purchase 67,788 shares and 34,016 shares at
exercise prices of $2.25 and $0.16, respectively were outstanding. Each of the
warrants are exercisable within five years from the date of purchase, and were
valued using the Black Scholes model, however the warrants were not recorded
separately in the financial statements.

     During fiscal 1998, in connection with the convertible promissory note
financing, the Company issued 871,226 warrants to purchase Series B Preferred
Stock to investors. The warrants are exercisable at a price of $1.54 per share
within ten years from date of issuance, and were valued using the Black Scholes
model, however the warrants were not recorded separately in the financial
statements.

     The holders/subscribers of shares of stock and stock warrants are subject
to the restrictions set forth in Shareholder Agreements/Subscription Agreements.
The terms of these agreements primarily relate to the right of first refusal.
Before any common shareholder may sell or otherwise transfer any share of common
stock, such shares shall first be offered to the Company.

(10) RETIREMENT BENEFIT PLAN

     The Company sponsors a defined contribution 401(k) plan (the Retirement
Plan). Employees who are at least 21 years old are eligible to participate in
the Retirement Plan beginning the month subsequent to employment. Participants

     Total rent expense under operating leases was $18,284, $93,011 and $230,182
for the period from November 21, 1995 (date of inception) through September 30,
1996 and for the years ended September 30, 1997 and 1998, respectively.

Litigation

     From time to time the Company may be involved in various legal actions in
the normal course of business. Management is of the opinion that the outcome of
such actions will not have a material adverse effect on the Company's financial
condition.

(12) CUSTOMER INFORMATION

     The Company had one customer that accounted for approximately 25% and 59%
in 1997 and 1998, respectively, of the Company's revenues.

(13) RISK OF TECHNOLOGICAL CHANGE

Contingencies and Factors that Could Affect Future Results

     A substantial portion of the Company's revenues each year are generated
from the development of websites and market research performed over the
Internet. In the extremely competitive industry environment in which the Company
operates, such product generation, development and marketing processes are
uncertain and complex, requiring accurate prediction of demand as well as
successful management of various development risks inherent to the Internet. In
light of these dependencies, it is possible that failure to successfully manage
future changes in technology with respect to the Internet could have long-term
impact on the Company's growth and results of operations.

(14) SUBSEQUENT EVENTS

     The convertible promissory notes issued October 1997 were converted on
October 9, 1998 to 732,895 shares of Series B Preferred Stock at $1.54 per
share.

     The $600,000 bank line of credit, due October 1998, was subsequently
amended. The new Agreement reduced the line to $500,000 and extends maturity
through December 31, 1998. A warrant to purchase 16,234 shares of Series B
Preferred Stock was granted in consideration for this Amendment. The fair value
of the warrant will be calculated using the Black-Scholes pricing model under
SFAS 123 and will be expensed in the first quarter of the fiscal year ending
September 30, 1999.

(15) UNAUDITED RECENT DEVELOPMENT

     On January 25, 1999, WebMD acquired all the issued and outstanding shares
of the Company's common and preferred stock for 1,619,190 shares of WebMD's
Series B preferred stock.

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Description of Business -- The Stockton Group, Inc. (the "Company"), was
incorporated as an S Corporation in the State of South Carolina in July 1993.
The Company provides computer-based prescription drug claims processing to
Pharmaceutical Benefit Managers ("PBMs"), Health Maintenance Organizations
("HMOs"), Preferred Provider Organizations ("PPOs"), insurance companies,
Third-Party Administrators ("TPAs"), self-insured employers, and Taft-Hartley
Funds. The Company's services range from claims processing to full-service
program management, including eligibility verification, drug coverages and
exclusions, concurrent utilization review, drug pricing verification, supply
limitations and other applicable plan design requirements. The Company supports
a network of over 40,000 pharmacies nationwide.

     In addition to claims processing fees, the Company receives rebate revenue
from drug manufacturers for prescription drug transactions that are processed
through the Company's system.

     Use of Estimates in the Preparation of Financial Statements -- The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

     Major Customers -- For the year ended June 30, 1997, three customers
accounted for approximately 15%, 12% and 10%, respectively, of total revenues.

     Revenue Recognition -- Revenue from prescription drug claims processing
services and rebates from drug manufacturers are recognized when the services
are delivered.

     Property and Equipment -- Property and equipment is depreciated using the
double-declining balance method over the estimated useful lives of the related
assets. Assets under capital leases are depreciated using the straight-line
method over the lease term.

     Income Taxes -- The Company has elected to be taxed as an S Corporation,
and as such its income is included in the current taxable income of its
stockholder. Accordingly, no provision has been made in the accompanying
financial statements for federal or state income taxes.

     Unaudited Interim Financial Statement -- In the opinion of management, the
unaudited statement of income for the three months ended September 30, 1997 is
presented on a basis consistent with the audited statement of income and
reflects all adjustments, consisting of only normal recurring adjustments,
necessary for a fair presentation of the results thereof. The results of
operations for the three months ended September 30, 1997 is not necessarily
indicative of the results to be expected for the entire year.

2. NOTE PAYABLE TO STOCKHOLDER

     The Company had a note payable to stockholder with an outstanding principal
balance of $359,621 at June 30, 1997. The note bore interest at a rate of prime
plus .25% (8.75% at June 30, 1997).

3. LEASE COMMITMENTS

     The Company leased certain equipment under operating leases expiring at
various dates through April 2000. Rent expense for the year ended June 30, 1997
was approximately $12,000.

                            THE STOCKTON GROUP, INC.

                  NOTES TO FINANCIAL STATEMENT -- (CONTINUED)
              YEAR ENDED JUNE 30, 1997 AND THE THREE MONTHS ENDED
                         SEPTEMBER 30, 1997 (UNAUDITED)
   (INFORMATION AS IT RELATES TO THE THREE MONTHS ENDED SEPTEMBER 30, 1997 IS
                                   UNAUDITED)

     In addition, the Company leased its office facility and certain computer
and office equipment under capital lease arrangements with interest rates
ranging from 14.5% to 25%, expiring through July 2011. The lease arrangement for
the office facility was with a corporation in which the Company's sole
stockholder holds an ownership interest.

4. STOCK-BASED COMPENSATION ARRANGEMENTS

     During 1994, the Company granted a key employee the right to acquire common
stock equivalent to a 25% equity ownership in the Company at no cost. The shares
have not yet been issued. At the date of the grant, the Company recorded
compensation cost equal to the fair market value of shares to be awarded to the
executive.

     During 1997, the Company entered into an employment agreement with another
new key executive. Among other things, the agreement granted the executive the
right to acquire a 10% equity ownership in the Company at a nominal cost ($1.00)
or, if the Company is sold within one year, to receive 10% of the sales proceeds
as defined. Accordingly, the Company has recorded compensation cost in 1997,
equal to the estimated cash settlement to be paid to the executive based upon
the anticipated proceeds from the sale of the Company. (See Note 5).

5. SUBSEQUENT EVENT

     In November 1997, the Company sold certain computer equipment, intangible
assets and the operations of the Company to MEDE America Corporation. All other
assets and liabilities remained with the Company. The purchase price was
$10,400,000 in cash. In addition, the purchase agreement requires additional
consideration of up to $2,600,000 (plus interest at an annual rate of 7.25%) to
be paid if Stockton's revenue during the 12-month period ended September 30,
1998 is at least $5,000,000.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Healthcare Interchange, Inc.:

     We have audited the accompanying consolidated balance sheet of Healthcare
Interchange, Inc. and subsidiary (Company) as of June 30, 1998, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for the nine-month period ended June 30, 1998. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audit.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

     As described in notes 3 and 15, on October 30, 1998, the Company completed
the sale of its financial transactions business to MEDE America and the disposal
of the assets and operations of the discontinued Telemedical and Intercare
segments.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Healthcare
Interchange, Inc. and subsidiary as of June 30, 1998, and the results of their
operations and their cash flows for the nine-month period ended June 30, 1998,
in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                      JUNE 30, 1998 AND FOR THE NINE-MONTH
                           PERIOD ENDED JUNE 30, 1998

1. ORGANIZATION AND BUSINESS

     Healthcare Interchange, Inc. was incorporated in 1991 and began operations
in 1992. Healthcare Interchange, Inc. and subsidiary (Company) is in the
business of providing electronic health data network services to a national
clientele through three operating segments; financial transactions, medical
televideo, and intercare. The financial transactions segment processes
electronic claims for health care providers. The medical televideo segment
develops, sells, and services televideo and minor medical equipment through a
wholly owned subsidiary, HII Telemedical Corp. (Telemedical). The Intercare
segment (Intercare) began operations in fiscal 1997, providing electronic claims
processing and data analysis for health care providers. Prior to October 1,
1996, Intercare was a development stage enterprise.

     The consolidated financial statements at June 30, 1998 include the accounts
of Healthcare Interchange, Inc. and its wholly owned domestic subsidiary after
elimination of intercompany accounts and transactions. The Company's fiscal year
end is September 30.

     Unaudited Interim Consolidated Financial Statements -- The consolidated
balance sheet of the Company as of September 30, 1998 and the related
consolidated statements of operations, changes in stockholders' equity (deficit)
and cash flows for the three-month period ended September 30, 1998 included in
the accompanying consolidated financial statements, which are unaudited, include
the accounts of Healthcare Interchange, Inc. and its wholly-owned subsidiary.
All significant intercompany accounts have been eliminated in consolidation. In
the opinion of management, all adjustments necessary for a fair presentation of
such financial statements have been included. Adjustments consist only of normal
recurring items.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a. Cash and Cash Equivalents -- The Company considers cash equivalents to
be securities held for cash management purposes having original maturities of
three months or less at the time of investment.

     b. Inventories -- Inventories are stated at the lower of cost or market.
Cost is determined principally using the specific identification method.
Inventories at June 30, 1998 are comprised principally of raw materials.

     c. Property, Equipment and Computer Software -- Property, equipment and
computer software are carried at cost. Depreciation and amortization is
calculated using the straight-line method over the estimated useful lives of the
assets. Leasehold improvements are amortized over the shorter of the lease term
or estimated useful life of the asset. Costs associated with the internal
development of software are capitalized once the marketability and technological
feasibility of the software have been established.

     The property, equipment and computer software are depreciated on the
straight-line basis over the following useful lives:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      JUNE 30, 1998 AND FOR THE NINE-MONTH
                           PERIOD ENDED JUNE 30, 1998

     d. Income Taxes -- Deferred tax assets and liabilities are recognized for
the estimated future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates in effect for the year in which those differences are
expected to be recovered or settled.

     e. Revenue Recognition -- The Company recognizes revenue from the sale of
its services in the period that the services are delivered or provided. Unearned
income on service contracts is amortized by the straight-line method over the
term of the contracts.

     Revenue from the sale of the Company's products is recognized in the period
that the products are shipped to the customers.

     f. Stock-Based Compensation -- The Company uses the intrinsic value method
prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" (APB 25), and related interpretations in accounting for its
stock options. The Company has adopted the pro forma disclosures-only provisions
of Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation."

     g. Use of Estimates -- The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements. Estimates also affect the reported amounts of revenues
and expenses during the period. Actual results may differ from those estimates.

3. DISCONTINUED OPERATIONS

     In fiscal 1999, the Company's Board of Directors approved a plan to
discontinue the operations of its Televideo and Intercare operating segments;
and on September 17, 1998, signed a letter of intent to sell substantially all
the assets of the financial transactions business to MEDE America Corporation
(MEDE America). See note 15.

     The Company's consolidated financial statements as of June 30, 1998 and for
the nine-month period then ended include a charge of $2,073,601 to provide for
an after-tax loss on the disposal of the discontinued operations, including
estimated operating losses of $342,971 through the expected date of disposal.

     Operating results for the nine-month period ended June 30, 1998 and
financial position as of June 30, 1998 of the discontinued segments are
summarized below:

6. REVOLVING CREDIT FACILITIES

     On November 4, 1996, the Company entered into a revolving credit facility
with a local bank which allows the Company to borrow up to a maximum of
$750,000. The revolving credit facility bears interest at a fixed prime plus 1%
(9.5% at June 30, 1998) and requires monthly payments of interest. The due date
on the revolving credit facility has been extended from the original December
31, 1997 due date and is now due on October 31, 1998. The average outstanding
borrowings on the revolving credit facility arrangement was $750,000 at a
weighted average interest weight of 9.6% for the nine-month period ended June
30, 1998. The revolving credit facility had a balance of $750,000 at June 30,
1998.

     On November 4, 1996, the Company entered into a revolving credit facility
with a local bank which allows the Company to borrow up to a maximum of
$500,000. The revolving credit facility bears interest at

                           PERIOD ENDED JUNE 30, 1998

a fixed prime less 0.5% (8.0% at June 30, 1998) and requires monthly payments of
interest, with the balance due on November 4, 1998. The average outstanding
borrowings on the revolving credit facility was $500,000 at a weighted average
interest weight of 8.1% for the nine-month period ended June 30, 1998. The
revolving credit facility had a balance of $500,000 at June 30, 1998.

     On June 4, 1997, the Company entered into a revolving credit facility with
a local bank which allows the Company to draw up to a maximum of $2,500,000. The
revolving credit facility bears an interest rate of prime less 0.625% (7.88% at
June 30, 1998), requires monthly payments of interest, and is secured by
substantially all assets of the Company with the balance due on December 31,
1999. The average outstanding borrowings on the revolving credit facility was
approximately $877,000 at a weighted average interest rate of 8.0% for the
nine-month period ended June 30, 1998. The revolving credit facility had a
balance of $1,010,000 at June 30, 1998.

     As of June 30, 1998, the carrying value of the Company's revolving credit
facilities approximated fair value based upon borrowing rates currently
available for debt instruments with similar remaining terms and maturities. The
Company's $750,000 revolving credit facility and notes payable are secured by
substantially all of the Company's assets. Additionally, the $500,000 and
$2,500,000 revolving credit facilities are guaranteed by two of the Company's
stockholders.

     The Company's commitment agreement with the local bank for the notes
payable and revolving credit facilities contains restrictive covenants which
include the maintenance of minimum tangible net worth, as defined, and certain
financial ratios. The Company failed to meet certain covenant requirements which
has placed the Company in technical default. Consequently, the Company has
classified the entire outstanding balance of borrowings under the notes payable
and revolving credit facilities as a current liability.

7. NOTES PAYABLE

     On February 28, 1995, the Company entered into a $300,000 note payable with
a local bank. The note was paid in full by the Company in February 1998. The
note payable accrued interest at a fixed rate of 9.0% and required monthly
payments of principal and interest.

     On May 30, 1995, the Company entered into a $170,000 note payable with a
local bank. The note bears interest at a fixed rate of 9.75%, requires monthly
payments of principal and interest, with the balance due on May 30, 2000, and is
secured by substantially all assets of the Company. The note is payable on
demand, and accordingly, is classified as a current liability. The balance at
June 30, 1998 was $73,751.

8. RELATED PARTY TRANSACTIONS

     During the nine-month period ended June 30, 1998, two stockholders provided
network and other services to the Company. Total expenses incurred by the
Company for these services totaled approximately $116,000 for the nine-month
period ended June 30, 1998. At June 30, 1998, the Company owed approximately
$152,000, to these stockholders for such services.

     Revenue received from services provided to stockholders totaled
approximately $844,000 for the nine-month period ended June 30, 1998. Due from
stockholders represents amounts receivable for services provided to the
stockholders.

10. STOCKHOLDERS' EQUITY

     Each share of cumulative convertible preferred stock (Preferred Stock) held
and issuable to common holders requires a $1.50 annual dividend. Preferred Stock
is redeemable, at the option of the Company, for cash of $24 per share plus
unpaid dividends quarterly. Each share of Preferred Stock is convertible, at the
option of the holder, into a share of common stock (the class of common stock
the holder already owns) upon change in control of the Company or sale of
substantially all the Company's assets, as defined in the Company's Articles of
Incorporation. The Company has reserved 31,250 shares of Class A and Class B
common stock for the purpose of effecting the conversion of the Preferred Stock.

     Pursuant to an agreement between all stockholders and the Company, all
preferred and common stock outstanding is subject to certain restrictions on
disposition and transfer. The stockholder agreement requires that stockholders
must first offer shares to be sold or transferred to other stockholders and/or
the Company in accordance with terms specified in the stockholder agreement.

11. EMPLOYEE STOCK OPTION PLANS

     1994 Stock Option Plan -- On March 22, 1994, the Board of Directors of the
Company adopted the 1994 Stock Option Plan (1994 Plan) pursuant to which
incentive stock options may be granted to employees or directors. Under the 1994
Plan, options to purchase 12,000 shares of Class C common stock may be granted
for a term not to exceed 10 years (five years with respect to a stockholder who
owns more than 10% of the capital stock of the Company) and must be granted
within 10 years from the date of adoption of the 1994 Plan. The exercise price
of all stock options must be at least equal to the fair market value (110% of
fair market value for a stockholder who owns more than 10% of the capital stock
of the Company) of the shares on the date granted.

     1997 Stock Option Plan -- On October 30, 1997, the Company's Board of
Directors adopted a second stock option plan, the 1997 Stock Option Plan (1997
Plan). The purpose of the 1997 Plan is to provide additional employee
incentives. Under the 1997 Plan, up to 24,000 options to purchase Class C common
stock may be granted. The other significant provisions under the 1997 Plan are
similar to those under the 1994 Plan, as described above.

     No compensation expense relating to stock option grants was recorded in the
nine-month period ended June 30, 1998 as the option exercise prices were equal
to the estimated fair value at the dates of grant.

     Pro forma information regarding loss and loss per share is required by SFAS
No. 123, and has been determined as if the Company had accounted for its stock
options under the fair value method of SFAS No. 123. However, the full impact of
calculating compensation cost for stock options under SFAS No. 123 is not
reflected in the pro forma net loss amounts presented below as compensation cost
does not reflect options granted prior to October 1, 1996 which vest subsequent
to that date. The fair value for options granted in the nine-month period ended
June 30, 1998 was estimated at the date of grant using a Black-Scholes option
pricing model with the following weighted average assumptions:

12. EMPLOYEE BENEFIT PLAN

     The Company maintains a qualified, contributory, 401(k) profit-sharing plan
covering substantially all employees. Employees are allowed to contribute
between 1% and 15% of their compensation to the plan, not to exceed the
statutory maximum. The plan provides for contributions by the Company of 50% of
the first 6% of an employee's salary deferral. The plan also provides for
discretionary contributions by the Company in such amounts as the Board of
Directors may annually determine. There were no discretionary contributions made
in the nine-month period ended June 30, 1998. Expense associated with the plan
for continuing operations of the Company totaled $39,371 for the nine-month
period ended June 30, 1998.

13. INCOME TAXES

     No provision for income taxes was recorded for the nine-month period ended
June 30, 1998, as substantially all income tax attributable to continuing and
discontinued operations was offset by the utilization of net operating loss
carryforwards.

     The difference between the effective income tax rate applied to income from
continuing operations for financial statement purposes and the U.S. federal
income tax rate of 34% for the nine-month period ended June 30, 1998 is as

</TABLE>

     SFAS No. 109 requires that a valuation allowance be established for
deferred tax assets if, based on the weight of evidence, it is more likely than
not that some portion or all of the deferred tax asset will not be realized. The
ultimate realization of deferred tax assets is dependent upon the generation of
future taxable income during the periods in which those temporary differences
become deductible. Management considers the scheduled reversal of deferred tax
liabilities, projected future taxable income, and tax planning strategies in
making this assessment. The Company has approximately $3,500,000 of net
operating loss carryforwards for income tax purposes, which will begin to expire
in the year 2009.

14. YEAR 2000

     The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have date-sensitive software may recognize a "00" date as
the year 1900 rather than the year 2000. This could result in computer system
failures or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions or engage in normal
business activities. The Company has developed a Year 2000 remediation plan and
has begun testing and converting its computer systems and applications in order
to identify and solve significant Year 2000 issues. In addition, the Company is
discussing with its vendors the possibility of any communication difficulties or
other disruptions that may affect the Company.

                      AGREEMENT AND PLAN OF REORGANIZATION

     This AGREEMENT AND PLAN OF REORGANIZATION is made and entered into as of
May 20, 1999, among Healtheon Corporation, a Delaware corporation ("PARENT"),
Water Acquisition Corp., a Georgia corporation and a wholly-owned subsidiary of
Parent ("MERGER SUB"), and WebMD, Inc., a Georgia corporation (the "COMPANY").

                                    RECITALS

     A. Upon the terms and subject to the conditions of this Agreement and in
accordance with the Georgia Business Corporation Code ("GEORGIA LAW"), Parent,
Merger Sub and the Company intend to enter into a business combination
transaction.

     B. The Board of Directors of the Company (i) has determined that the Merger
(as defined in Section 1.1) is consistent with and in furtherance of the
long-term business strategy of the Company and fair to, and in the best
interests of, the Company and its stockholders, (ii) has approved this
Agreement, the Merger and the other transactions contemplated by this Agreement
and (iii) has determined to recommend that the stockholders of the Company adopt
and approve this Agreement and approve the Merger.

     C. The Board of Directors of Parent (i) has determined that the Merger (as
defined in Section 1.1) is consistent with and in furtherance of the long-term
business strategy of Parent and fair to, and in the best interests of, Parent
and its stockholders, (ii) has approved this Agreement, the Merger and the other
transactions contemplated by this Agreement, and (iii) has determined to
recommend that the stockholders of Parent approve the issuance of shares of
Parent Common Stock (as defined below) pursuant to the Merger.

     D. Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's and Company's respective willingness to enter into
this Agreement, certain stockholders of the Company are entering into Voting
Agreements in substantially the form attached hereto as Exhibit A-1 (the
"COMPANY VOTING AGREEMENTS"), certain stockholders of the Company are entering
into Conversion Agreements in substantially the form attached hereto as Exhibits
B-1, B-2, B-3, and B-4 (the "COMPANY CONVERSION AGREEMENTS"), and Microsoft
Corporation ("MICROSOFT") is entering into a Stockholder Agreement (the
"MICROSOFT AGREEMENT") in substantially the form of Exhibit C, (Exhibit C is
included in the definition of Company Voting Agreements for the purposes
hereof). Certain Stockholders of Parent are entering into Voting Agreements in
substantially the form attached hereto as Exhibit D (the "PARENT VOTING
AGREEMENTS").

     E. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "CODE").

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties agree
as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1  The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of Georgia Law, Merger Sub shall be merged with and into
the Company (the "MERGER"), the separate corporate existence of Merger Sub shall
cease and the Company shall continue as the surviving corporation. The Company,
as the surviving

                                       -1-
<PAGE>   390

corporation after the Merger, is hereinafter sometimes referred to as the
"SURVIVING CORPORATION". Notwithstanding the foregoing:

        (a) Parent and the Company may, at any time prior to the mailing of the
Proxy Statement/ Prospectus (as defined in Section 2.19 below), mutually agree
to change the structure of the Merger to a forward triangular merger with the
Company merging with and into Merger Sub and Merger Sub surviving the Merger. In
such event, Merger Sub, as the surviving corporation after the Merger, is
hereinafter sometimes referred to as the "SURVIVING CORPORATION".

        (b) Parent or the Company may, at any time prior to the mailing of the
Proxy Statement/ Prospectus, reasonably require that the structure of the Merger
be pursuant to a new Delaware corporation referred to herein as Newco would be
formed by Parent and the Company solely for the purpose of the transactions
contemplated hereunder; (i) a newly formed, wholly owned subsidiary of Newco
incorporated in Delaware would be merged with and into Parent, with Parent being
the surviving corporation of such merger (the "PARENT MERGER"), and all
outstanding shares of Parent Common Stock would be converted, on a share for
share basis, into shares of Newco Common Stock having identical rights,
preferences and privileges, as shares of Parent Common Stock; and (ii) another
newly formed, wholly owned subsidiary of Newco incorporated in Georgia would be
merged with and into the Company, with the Company being the surviving
corporation of such merger (the "COMPANY MERGER"), and all outstanding shares of
Company Capital Stock will be automatically converted into the right to receive
shares of Newco Common Stock in the same manner specified in Section 1.6(a)
below as if the Newco Common Stock were Parent Common Stock; provided that each
share of any series or class of Company Capital Stock that, as a separate voting
group under Georgia Law has a right to approve the Company Merger as a separate
voting group, does not in fact approve the Company Merger (a "NON APPROVING
SERIES") outstanding prior to the Company Merger would remain outstanding as a
share of the applicable series or class in the Company thereafter. For federal
income tax purposes, it is intended that the Parent Merger and the Company
Merger qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code and/or as an exchange under the provisions of Section
351(a) of the Internal Revenue Code. For purposes of this Agreement, the Parent
Voting Agreements, the Company Voting Agreements and the Company Conversion
Agreements, the term Merger as used herein and therein shall be deemed to mean
the Parent Merger and/or the Company Merger, as applicable. If the alternative
in this paragraph (b) is applicable, the parties shall execute an appropriate
amendment to this Agreement to effect such changes as are necessary and
appropriate to effect the structure of the Merger described in this paragraph
and to provide that Newco shall cause the Company to honor the Company's
warrants and to provide shares of Newco common stock upon exercise of such
securities.

     1.2  Effective Time; Closing. Subject to the provisions of this Agreement,
the parties hereto shall cause the Merger to be consummated by filing Articles
of Merger with the Secretary of State of the State of Georgia in accordance with
the relevant provisions of Georgia Law (the "ARTICLES OF MERGER") (the time of
such filing with the Secretary of State of the State of Georgia (or such later
time as may be agreed in writing by the Company and Parent and specified in the
Articles of Merger) being the "EFFECTIVE TIME") as soon as practicable on or
after the Closing Date (as herein defined). Unless the context otherwise
requires, the term "AGREEMENT" as used herein refers collectively to this
Agreement and Plan of Reorganization and the Articles of Merger. The closing of
the Merger (the "CLOSING") shall take place at the offices of Wilson Sonsini
Goodrich & Rosati, Professional Corporation, at a time and date to be specified
by the parties, which shall be no later than the second business day after the
satisfaction or waiver of the conditions set forth in Article VI, or at such
other time, date and location as the parties hereto agree in writing (the
"CLOSING DATE").

     1.3  Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement and the applicable provisions of Georgia
Law. Without limiting the generality of the foregoing, and subject thereto, at
the Effective Time all the property, rights, privileges, powers and franchises
of the Company and Merger Sub shall vest in the Surviving Corporation, and all
debts, liabilities and duties of the Company and Merger Sub shall become the
debts, liabilities and duties of the Surviving Corporation.

        (a) Subject to Section 5.11, at the Effective Time, the Articles of
Incorporation of Merger Sub, as in effect immediately prior to the Effective
Time, shall be the Articles of Incorporation of the Surviving Corporation until
thereafter amended as provided by law and such Articles of Incorporation of the
Surviving Corporation; provided, however, that at the Effective Time the
Articles of Incorporation of the Surviving Corporation shall be amended so that
the name of the Surviving Corporation shall be "WebMD, Inc."

        (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be, at the Effective Time, the Bylaws of the Surviving

     1.5  Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of the Company immediately prior to the Effective Time, until their
respective successors are duly appointed.

     1.6  Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any action
on the part of Merger Sub, the Company or the holders of any of the following
securities, the following shall occur:

        (a) Conversion of Company Capital Stock. Each share of Common Stock of
the Company ("COMPANY COMMON STOCK") issued and outstanding immediately prior to
the Effective Time, other than any Dissenting Shares (as defined in Section
1.7(a) hereof), and other than any shares of the Company Capital Stock to be
canceled pursuant to Section 1.6(b), will be canceled and extinguished and
automatically converted, without regard to any conversion rights contained in
the Company's Articles of Incorporation, into the right to receive 1.815 shares
of Parent Common Stock (the "EXCHANGE RATIO") (subject to Section 1.6(f)) upon
surrender of the certificate representing such share of the Company Capital
Stock in the manner provided in Section 1.7 (or in the case of a lost, stolen or
destroyed certificate, upon delivery of an affidavit (and bond, if required) in
the manner provided in Section 1.10). Each share of Preferred Stock of the
Company ("COMPANY PREFERRED STOCK" and together with the Company Common Stock,
the "COMPANY CAPITAL STOCK") issued and outstanding immediately prior to the
Effective Time (other than Dissenting Shares) will be cancelled and extinguished
and automatically converted without regard to any conversion rights or rights to
receive any liquidation or other preference contained in the Company's Articles
of Incorporation into the right to receive a number of shares of Parent Common
Stock equal to (i) the Exchange Ratio (subject to Section 1.6(f)) multiplied by
(ii) the number of shares of Company Common Stock into which such share of
Company Preferred Stock is convertible immediately prior to the Effective Time
(without giving effect to any limitations on the exercise of such conversion
right), upon surrender of the certificate representing such Company Preferred
Stock, in the manner provided in Section 1.7 (or in the case of a lost, stolen
or destroyed certificate, upon delivery of an affidavit (and bond) if required)
in the manner provided in Section 1.10. If any shares of Company Capital Stock
outstanding immediately prior to the Effective Time (but giving effect to the
Merger) are unvested or are subject to a repurchase option, risk of forfeiture
or other similar condition under any applicable restricted stock purchase
agreement or other similar agreement with the Company, then the shares of Parent
Common Stock issued in exchange for such shares of Company Capital Stock will
also be unvested and subject to the same repurchase option, risk of forfeiture
or other similar condition (except as provided in the applicable agreement or
plan), and the certificates representing such shares of Parent Common Stock may
accordingly be marked with appropriate legends. The Company shall take all
action that may be necessary to ensure that, from and after the Effective Time,
Parent or the Surviving Corporation is entitled to exercise any such repurchase
option or other right set forth in any such restricted stock purchase agreement
or other similar agreement.

        (b) Cancellation of Parent-Owned Stock. Each share of Company Capital
Stock held by the Company or owned by Merger Sub, Parent or any direct or
indirect wholly-owned subsidiary of the Company or of Parent immediately prior
to the Effective Time shall be canceled and extinguished without any conversion
thereof.

connection with the Merger, assumed by Parent in accordance with Section 5.9.
Part 2.2 of the Company Schedules describes, with respect to each warrant
outstanding, the number of shares of Company Capital Stock into which such
warrant may be exercised, the exercise price, the name and address of the holder
of record, the grant date, the termination date, whether such warrant has
registration rights, and, if applicable, a description of such registration
rights and whether cashless exercise of such warrant is permissible.

        (d) Capital Stock of Merger Sub. Each share of Common Stock of Merger
Sub (the "MERGER SUB COMMON STOCK") issued and outstanding immediately prior to
the Effective Time shall be converted into one validly issued, fully paid and
nonassessable share of Common Stock of the Surviving Corporation. Each
certificate evidencing ownership of shares of Merger Sub Common Stock shall
evidence ownership of such shares of capital stock of the Surviving Corporation.

        (e) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued by virtue of the Merger, but in lieu thereof each holder of
shares of Company Capital Stock who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall, upon
surrender of such holder's Certificate(s) (as defined in Section 1.8(c)),
receive from Parent an amount of cash (rounded to the nearest whole cent),
without interest, equal to the product of (i) such fraction, multiplied by (ii)
the average closing price of one share of Parent Common Stock for the ten (10)
most recent days that Parent Common Stock has traded ending on the trading day
ending one day prior to the Closing Date, as reported on the Nasdaq National
Market System ("NASDAQ").

        (f) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted
to reflect appropriately the effect of any stock split, reverse stock split,
stock dividend (including any dividend or distribution of securities convertible
into Parent Common Stock or Company Capital Stock), reorganization,
recapitalization, reclassification or other like change with respect to Parent
Common Stock or Company Capital Stock occurring on or after the date hereof and
prior to the Effective Time.

     1.7  Dissenting Shares.

        (a) Notwithstanding any other provisions of this Agreement to the
contrary, any shares of Company Capital Stock held by a holder who has exercised
dissenters' rights for such shares in accordance with Georgia Law and who, as of
the Effective Time, has not effectively withdrawn or lost such dissenters'
rights ("DISSENTING SHARES"), shall not be converted into or represent a right
to receive the consideration for Company Capital Stock set forth in Section 1.6
hereof, but the holder thereof shall only be entitled to such rights as are
provided by Georgia Law.

        (b) Notwithstanding the provisions of Section 1.7(a) hereof, if any
holder of Dissenting Shares shall effectively withdraw or lose (through failure
to perfect or otherwise) such holder's dissenters' rights under Georgia Law,
then, as of the later of the Effective Time and the occurrence of such event,
such holder's shares shall automatically be converted into and represent only
the right to receive the consideration for Company Capital Stock set forth in
Section 1.6 hereof, without interest thereon, upon surrender of the certificate
representing such shares.
                                       -4-
<PAGE>   393

        (c) The Company shall give Parent (i) prompt notice of any written
demand for appraisal received by the Company pursuant to the applicable
provisions of Georgia Law; and (ii) the opportunity to participate in all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of Parent, make any payment with
respect to any such demands or offer to settle or settle any such demands.

     1.8  Surrender of Certificates.

        (a) Exchange Agent. Parent shall select an institution reasonably
satisfactory to the Company to act as the exchange agent (the "EXCHANGE AGENT")
in the Merger.

        (b) Parent to Provide Common Stock. Promptly after the Effective Time,
Parent shall make available to the Exchange Agent for exchange in accordance
with this Article I, the shares of Parent Common Stock issuable pursuant to
Section 1.6 in exchange for outstanding shares of Company Capital Stock, and
cash in an amount sufficient for payment in lieu of fractional shares pursuant
to Section 1.6(e) and any dividends or distributions which holders of shares of
Company Capital Stock may be entitled pursuant to Section 1.8(d).

        (c) Exchange Procedures. Promptly after the Effective Time, Parent shall
cause the Exchange Agent to mail to each holder of record (as of the Effective
Time) of a certificate or certificates (the "CERTIFICATES") which immediately
prior to the Effective Time represented outstanding shares of Company Capital
Stock whose shares were converted into the right to receive shares of Parent
Common Stock pursuant to Section 1.6, cash in lieu of any fractional shares
pursuant to Section 1.6(f) and any dividends or other distributions pursuant to
Section 1.8(d), (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Parent Common Stock, cash in
lieu of any fractional shares pursuant to Section 1.6(e) and any dividends or
other distributions pursuant to Section 1.8(d). Upon surrender of Certificates
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, the holders of
such Certificates shall be entitled to receive in exchange therefor certificates
representing the number of whole shares of Parent Common Stock, payment in lieu
of fractional shares which such holders have the right to receive pursuant to
Section 1.6(e) and any dividends or distributions payable pursuant to Section
1.8(d), and the Certificates so surrendered shall forthwith be canceled. Until
so surrendered, outstanding Certificates will be deemed from and after the
Effective Time, for all corporate purposes, subject to Section 1.8(d) as to the
payment of dividends, to evidence the ownership of the number of full shares of
Parent Common Stock, into which such shares of Company Capital Stock shall have
been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 1.6(e) and any
dividends or distributions payable pursuant to Section 1.8(d).

        (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holders of any unsurrendered Certificates with respect to the
shares of Parent Common Stock represented thereby until the holders of record of
such Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the record holders thereof, without interest, certificates representing whole
shares of Parent Common Stock issued in exchange therefor along with payment in
lieu of fractional shares pursuant to Section 1.6(e) hereof and the amount of
any such dividends or other distributions with a record date after the Effective
Time payable with respect to such whole shares of Parent Common Stock.

        (e) Transfers of Ownership. If certificates for shares of Parent Common
Stock are to be issued in a name other than that in which the Certificates
surrendered in exchange therefor are registered, it will be a condition of the
issuance thereof that the Certificates so surrendered will be properly endorsed
and
                                       -5-
<PAGE>   394

otherwise in proper form for transfer and that the persons requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of certificates for shares of
Parent Common Stock in any name other than that of the registered holder of the
Certificates surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

        (f) Required Withholding. Each of the Exchange Agent, Parent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Capital Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign tax law or under any other applicable Legal Requirement
(as defined in Section 2.2(c)). To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the person to whom such amounts would otherwise have been
paid.

        (g) No Liability. Notwithstanding anything to the contrary in this
Section 1.8, neither the Exchange Agent, Parent, the Surviving Corporation nor
any party hereto shall be liable to a holder of shares of Parent Common Stock or
Company Capital Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

     1.9  No Further Transfers of Company Capital Stock. There shall be no
further recordation of transfers on the stock books of the Surviving Corporation
of shares of Company Capital Stock which were outstanding immediately prior to
the Effective Time. If after the Effective Time Certificates are presented to
the Surviving Corporation for any reason, they shall be canceled and exchanged
as provided in this Article I.

     1.10  Lost, Stolen or Destroyed Certificates. In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such shares of Parent Common
Stock, cash for fractional shares, if any, as may be required pursuant to
Section 1.6(e) and any dividends or distributions payable pursuant to Section
1.8(d); provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against Parent, the Company or
the Exchange Agent with respect to the Certificates alleged to have been lost,
stolen or destroyed.

     1.11  Tax Consequences. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code. The parties hereto adopt this Agreement as a "plan of reorganization"
within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
Income Tax Regulations.

hereof there are no equity securities, partnership interests or similar
ownership interests of any class of any Company equity security, or any

reserved for issuance or outstanding. Except for securities the Company owns
free and clear of all claims and Encumbrances, directly or indirectly through
one or more subsidiaries, and except for shares of capital stock or other
similar ownership interests of certain subsidiaries of the Company that are

as of the date of this Agreement, there are no equity securities, partnership
interests or similar ownership interests of any class of equity security of any
subsidiary of the Company, or any security exchangeable or convertible into or

extend, accelerate the vesting of or enter into any such subscription, option,

requisite vote of the stockholders of the Company to approve and adopt this
Agreement and approve the Merger under each of the Company Charter Documents and
Georgia Law, including, without limitation the treatment of Company Capital
Stock as set forth in Section 1.6(a), are set forth on Part 2.4 of the Company
Schedules. Stockholders of the Company that have executed the Company Voting
Agreements and the Company Conversion Agreements, together with Parent's rights
under Section 5.2(c), represent sufficient voting power to approve the Merger

of the shares subject to such executed Company Voting Agreements are voted in
accordance with the terms of the Company Voting Agreements and all of the shares
subject to such Company Conversion Agreements are converted pursuant to the
terms thereof, together with Parent's rights under Section 5.2(c), the condition
set forth in Section 6.1(a) of this Agreement would be satisfied at the
Company's Stockholder's Meeting (as defined in Section 5.2). If Parent exercises
its option pursuant to Section 5.2(c), the option will be valid, binding and
enforceable and Parent will have all voting rights (which rights will be valid,
binding and enforceable) with respect to shares of Company Capital Stock, issued
or issuable upon exercise of such option.

     2.4  Authority; Non-Contravention.

        (a) The Company has all requisite corporate power and authority to enter
into this Agreement and to consummate the transactions contemplated hereby and
thereby. The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company, subject only to the approval and
adoption of this Agreement and the approval of the Merger by the Company's
stockholders and the filing of the Articles of Merger pursuant to Georgia Law.
This Agreement has been duly executed and delivered by the Company and, assuming
due execution and delivery by Parent and Merger Sub, constitutes a valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms, except as enforceability may be limited by bankruptcy and other
similar laws and general principles of equity. The execution and delivery of
this Agreement by the Company does not, and the performance of this Agreement by
the Company will not, (i) conflict with or violate the Company Charter
Documents; (ii) subject to obtaining the approval and adoption of this Agreement
and the approval of the Merger by the Company's stockholders as contemplated in
Section 5.2 and compliance with the requirements set forth in Section 2.4(b)
below, conflict with or violate any law, rule, regulation, order, judgment or
decree applicable to the Company or any of its subsidiaries or by which the
Company or any of its subsidiaries or any of their respective properties is
bound or affected; or (iii) result in any material breach of or constitute a
material default (or an event that with notice or lapse of time or both would
become a material default) under, or impair the Company's rights or alter the
rights or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a material lien or Encumbrance on any of the material properties or
assets of the Company or any of its subsidiaries pursuant to, any material note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise, concession, or other instrument or obligation to which the Company or
any of its subsidiaries is a party or by which the Company or any of its
subsidiaries or its or any of their respective assets are bound or affected.
Part 2.4(b) of the Company Schedules lists all consents, waivers and approvals
under any of the Company's or any of its subsidiaries' agreements, contracts,
licenses or leases required to be obtained in connection with the consummation

subsidiaries, nor, to Parent's knowledge, has any Governmental Entity indicated
an intention to conduct an investigation of Parent or any of its subsidiaries.
There is no material agreement, judgment, injunction, order or decree binding
upon Parent or any of its subsidiaries which has or could reasonably be expected

of Parent, threatened against, relating to or affecting Parent or any of its
subsidiaries, before any court, governmental department, commission, agency,
instrumentality or authority, or any arbitrator that seeks to restrain or enjoin
the consummation of the transactions contemplated by this Agreement or which
could reasonably be expected, either singularly or in the aggregate with all
such claims, actions or proceedings, to be material to Parent. No Governmental
Entity has at any time challenged or questioned in a writing delivered to Parent
the legal right of Parent to design, manufacture, offer or sell any of its
products or services in the present manner or style thereof. As of the date

be expected to, cause or provide a bona fide basis for a director or executive
officer of Parent to seek indemnification from Parent.

under any property, including the land and the improvements, ground water and
surface water thereof, that Parent or any of its subsidiaries has at any time

been designed to ensure date and time entry recognition, calculations that
accommodate same century and multi-century formulas and date values, leap year
recognition and calculations, and date data interface values that reflect the
century. Parent's products and internal systems manage and manipulate data
involving dates and times, including single century formulas and multi-century
formulas, and do not cause an abnormal ending scenario within the application or
generate incorrect values or invalid results involving such dates.

     3.15  Agreements, Contracts and Commitments. As of the date of this
Agreement, neither Parent nor any of its subsidiaries, nor to Parent's knowledge
any other party to a material Contract of Parent, is in breach, violation or
default under, and neither Parent nor any of its subsidiaries has received
written notice that it has breached, violated or defaulted under, any of the
material terms or conditions of any material Contract of Parent in such a manner
as would permit any other party to cancel or terminate any such material
Contract of Parent, or would permit any other party to seek material damages or
other remedies (for any or all of such breaches, violations or defaults, in the
aggregate).

Parent for inclusion in the Registration Statement will, at the Registration

regulations promulgated by the SEC thereunder, except that no representation or

reference therein based on information supplied by or on behalf of the Company
for inclusion or incorporation by reference in the Prospectus/Proxy Statement.

     5.2  Meeting of Company Stockholders.

     (a) Promptly after the date hereof, the Company will take all action
necessary in accordance with Georgia Law and its Articles of Incorporation and
Bylaws to convene a meeting of the Company's stockholders to consider adoption
and approval of this Agreement and approval of the Merger (the "COMPANY
STOCKHOLDERS' MEETING") to be held as promptly as practicable, and in any event
(to the extent permissible under applicable law) within 45 days after the
declaration of effectiveness of the Registration Statement. The Company shall
set the record date for the Company Stockholders' Meeting on the date which is
eight business days after the date the Prospectus/Proxy Statement is mailed to
the Company's stockholders. The Company will use its commercially reasonable
efforts to solicit from its stockholders proxies in favor of the adoption and
approval of this Agreement and the approval of the Merger and will take all
other action necessary or advisable to secure the vote or consent of its
stockholders required by Georgia Law to obtain such approvals. Notwithstanding
anything to the contrary contained in this Agreement, the Company may adjourn or
postpone the Company Stockholders' Meeting, but only to the extent necessary to
ensure that any necessary supplement or amendment to the Prospectus/Proxy
Statement is provided to Company stockholders in advance of a vote on the Merger
or, if as of the time for which Company Stockholders' Meeting is originally
scheduled (as set forth in the Prospectus/Proxy Statement) there are
insufficient shares of Company Capital Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Company
Stockholders' Meeting. The Company shall ensure that the Company Stockholders'
Meeting is called, noticed, convened, held and conducted, and that all proxies
solicited by the Company in connection with the Company Stockholders' Meeting
are solicited, in compliance with the Georgia Law, the Company's Articles of
Incorporation and Bylaws, and all other applicable legal requirements. The
Company's obligation to call, give notice of, convene and hold the Company
Stockholders' Meeting in accordance with this Section 5.2(a) shall not be
limited to or otherwise affected by (except to the extent set forth in this
Section 5.2(a)) the commencement, disclosure, announcement or submission to the
Company of any Acquisition Proposal, or by any withdrawal, amendment or
modification of the recommendation of the Board of Directors of the Company with
respect to the Merger, this Agreement or the transactions contemplated hereby.

        (b) The Board of Directors of the Company shall recommend that the
Company's stockholders vote in favor of and adopt and approve this Agreement and
approve the Merger at the Company Stockholders' Meeting or otherwise comply with
Section 14-2-1103 of Georgia Law (including without limitation subsection (b)(1)
thereof). Except as necessary so as not to breach its fiduciary duties to the
Company's stockholders under Georgia Law, the Prospectus/Proxy Statement shall
include a statement to the effect that the Board of Directors of the Company has
recommended that the Company's stockholders vote in favor of and adopt and
approve this Agreement and the Merger at the Company Stockholders' Meeting.
Except as necessary so as not to breach its fiduciary duties to the Company's
stockholders under Georgia Law, neither the Board of Directors of the Company
nor any committee thereof shall withdraw, amend or modify, or propose or resolve
to withdraw, amend or modify in a manner adverse to Parent, the recommendation
of the Board of Directors of the Company that the Company's stockholders vote in
favor of and adopt and approve this Agreement and the Merger. Notwithstanding
anything permitted by the

                                      -36-
<PAGE>   425

foregoing, neither the Company nor its Board of Directors shall take any action
that would cause any Company Voting Agreement or Company Conversion Agreement to
be unenforceable in accordance with its terms under applicable law.

        (c) If, on the date immediately prior to the record date for the Company
Stockholders Meeting, the shares of the Company Capital Stock subject to Company
Voting Agreements (including Company Voting Agreements entered into by parties
to Company Conversion Agreements) do not represent sufficient voting power to
approve the Merger (other than with respect to the required vote, if any, of the
Series A Preferred Stock or Series B Preferred Stock as separate voting groups),
then the Company will grant an option to Parent to purchase a sufficient number
of shares of Common Stock and/or Series F Preferred Stock, exercisable on the
record date at a price equal to $54.17 per share of Company Common Stock (on an
as-converted basis), payable by delivery of cash in the amount of the par value
per share of the shares purchased upon the exercise of such option(s), plus a
note of Parent with interest at 5% per annum for the remainder of the exercise
price, so as to provide such voting power. Any shares of Company Capital Stock
purchased pursuant to such option shall be subject to a put and call at the
exercise price of the option (payable by cancellation or return of the note, as
the case may be, together with cash in the amount of the cash purchase price) in
the event this Agreement is terminated prior to the Closing. The parties agree
to take such actions to ensure that the consummation of the transactions in this
Section (or such other substitute arrangements as the parties may mutually agree
to accomplish the purposes of this Section 5.2(c)) will not cause the Merger to
fail to constitute a tax-free transaction to the holders of Parent Common Stock
and Company Capital Stock under Section 368 or 351 of the Code.

     5.3  Meeting of Parent Stockholders.

        (a) Promptly after the date hereof, Parent will take all action

"PARENT STOCKHOLDERS MEETING") to consider (i) the issuance of the shares of
Parent Common Stock pursuant to the Merger (the "FIRST PROPOSAL"); (ii) an
amendment to the Parent Certificate of Incorporation to increase the number of
shares of Parent Common Stock and Preferred Stock of Parent authorized
thereunder and (iii) an amendment to Parent's certificate of Incorporation to
change its corporate name (subject to and conditional upon the effectiveness of
the Merger) (collectively, the "PARENT PROPOSALS"), to be held as promptly as
practicable, and in any event (to the extent permissible under applicable law)
within 45 days after the declaration of effectiveness of the Registration
Statement. Parent will use its commercially reasonable efforts to solicit from
its stockholders proxies in favor of the Parent Proposals and will take all
other action necessary or advisable to secure the vote or consent of its
stockholders required by the rules of Nasdaq or Delaware Law to obtain such
approvals. Notwithstanding anything to the contrary contained in this Agreement,
Parent may adjourn or postpone the Parent Stockholders' Meeting, but only to the
extent necessary to ensure that any necessary supplement or amendment to the
Prospectus/Proxy Statement is provided to Parent's stockholders in advance of a
vote on the Parent Proposals or, if as of the time for which Parent
Stockholders' Meeting is originally scheduled (as set forth in the
Prospectus/Proxy Statement) there are insufficient shares of Parent Common Stock
represented (either in person or by proxy) to constitute a quorum necessary to
conduct the business of the Parent's Stockholders' Meeting. Parent shall ensure
that the Parent Stockholders' Meeting is called, noticed, convened, held and
conducted, that all proxies solicited by the Company in connection with the
Parent Stockholders' Meeting are solicited in compliance with the Delaware Law,
its Certificate of Incorporation and Bylaws, the rules of Nasdaq and all other
applicable legal requirements. Parent's obligation to call, give notice of,
convene and hold the Parent Stockholders' Meeting in accordance with Section
5.3(a) shall not be limited or otherwise affected (except to the extent set
forth in this Section 5.3(a)) by the commencement, disclosure, announcement or
submission to Parent of any offer or proposal to acquire securities or assets of
Parent or its subsidiaries or any merger, consolidation, business combination or
similar transaction involving Parent, or by the withdrawal, amendment or
modification of the recommendation of the Board of Directors of Parent with
respect to the Merger, the Parent Proposals, this Agreement or the transactions
contemplated hereby.

        (b) The Board of Directors of Parent shall recommend that Parent's
stockholders vote in favor of the Parent Proposals or otherwise comply with

fiduciary duties to Parent's stockholders under Delaware Law, the
Prospectus/Proxy Statement shall include a statement to the effect that the
Board of Directors of Parent has recommended that Parent's stockholders vote in
favor of the Parent Proposals at the Parent Stockholders' Meeting. Except as
necessary so as not to breach its fiduciary duties to Parent's stockholders
under Delaware Law, neither the Board of Directors of Parent nor any committee
thereof shall withdraw, amend or modify, or propose or resolve to withdraw,
amend or modify in a manner adverse to the Company, the recommendation of the
Board of Directors of Parent that Parent's stockholders vote in favor of the
First Proposal. Except as provided in the previous sentence with respect to the
First Proposal, neither the Board of Directors of Parent nor any committee
thereof shall withdraw, amend or modify, or propose or resolve to withdraw,
amend or modify in a manner adverse to the Company, the recommendation of the
Board of Directors of Parent that Parent's stockholders vote in favor of the
Parent Proposals. Notwithstanding anything permitted by the foregoing, neither
Parent nor its Board of Directors shall take any action that would cause any
Parent Voting Agreement to be unenforceable in accordance with its terms under
applicable law.

Governmental Entities, if any) and the taking of all reasonable steps as may be
necessary to avoid any suit, claim, action, investigation or proceeding by any
Governmental Entity; (iii) the obtaining of all necessary consents, approvals or
waivers from third parties; (iv) the defending of any suits, claims, actions,

is or becomes applicable to the Merger, this Agreement or any of the
transactions contemplated by this

                                      -39-
<PAGE>   428

Agreement, use all reasonable efforts to ensure that the Merger and the other
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such statute or regulation on the Merger, this Agreement
and the transactions contemplated hereby. Notwithstanding anything herein to the
contrary, nothing in this Agreement shall be deemed to require Parent, the
Company or any subsidiary or affiliate thereof to agree to any divestiture by
itself or any of its affiliates of shares of capital stock or of any business,
assets or property, or the imposition of any material limitation on the ability
of any of them to conduct their businesses or to own or exercise control of such
assets, properties and stock.

        (b) The Company shall give prompt notice to Parent of any representation
or warranty made by it contained in this Agreement becoming untrue or
inaccurate, or any failure of the Company to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Section 6.3(a) or 6.3(b) would not be satisfied, provided, however,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

        (c) Parent shall give prompt notice to the Company of any representation
or warranty made by it or Merger Sub contained in this Agreement becoming untrue
or inaccurate, or any failure of Parent or Merger Sub to comply with or satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement, in each case, such that the conditions
set forth in Section 6.2(a) or 6.2(b) would not be satisfied, provided, however,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

     5.8  Third Party Consents. As soon as practicable following the date
hereof, Parent and the Company will each use its commercially reasonable efforts
to obtain any consents, waivers and approvals under any of its or its
subsidiaries' respective agreements, contracts, licenses or leases required to
be obtained in connection with the consummation of the transactions contemplated
hereby.

     5.9  Stock Options, Warrants and Employee Benefits.

        (a) At the Effective Time, each outstanding Company Option, whether or
not exercisable and regardless of the respective exercise prices thereof, will
be assumed by Parent. Each Company Option so assumed by Parent under this
Agreement will continue to have, and be subject to, the same terms and
conditions set forth in the applicable Company Stock Option Plan immediately
prior to the Effective Time (including, without limitation, any repurchase
rights or vesting provisions, but giving effect to any accelerated vesting and
exercisability resulting from the Merger), except that (i) each Company Option
will be exercisable (or will become exercisable in accordance with its terms)
for that number of whole shares of Parent Common Stock equal to the product of
the number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounded down to the nearest whole number of shares of Parent
Common Stock; and (ii) the per share exercise price for the shares of Parent
Common Stock issuable upon exercise of such assumed Company Option will be equal
to the quotient determined by dividing the exercise price per share of Company
Common Stock at which such Company Option was exercisable immediately prior to
the Effective Time by the Exchange Ratio, rounded up to the nearest whole cent.

        (b) It is intended that Company Options assumed by Parent shall qualify
following the Effective Time as incentive stock options as defined in Section
422 of the Code to the extent Company Options qualified as incentive stock
options immediately prior to the Effective Time and the provisions of this
Section 5.9 shall be applied consistent with such intent.

        (c) At the Effective Time, the Warrants will be assumed by Parent. Each
Warrant so assumed by Parent under this Agreement will continue to have, and be
subject to, the same terms and conditions set forth in the applicable warrant
agreement immediately prior to the Effective Time (including, without
limitation, any repurchase rights or vesting provisions), except that (i) each
Warrant will be exercisable

                                      -40-
<PAGE>   429

(or will become exercisable in accordance with its terms) for that number of
whole shares of Parent Common Stock equal to the product of (a) the number of
shares of Company Capital Stock that were issuable upon exercise of such Warrant
immediately prior to the Effective Time multiplied by (b) the number of shares
of Parent Common Stock into which such shares of Company Capital Stock would
have been converted pursuant to Section 1.6(a) had such shares been outstanding
immediately prior to the Effective Time (the "RATIO"), rounded to the nearest
whole number of shares of Parent Common Stock and (ii) the per share exercise
price for the share of Parent Common Stock issuable upon exercise of such
assumed Warrant will be equal to the quotient determined by dividing the
exercise price per share of Company Capital Stock at which such Warrant was
exercisable immediately prior to the Effective Time by the Ratio, rounded to the
nearest whole cent.

     5.10  Form S-8. Parent agrees to file, if available for use by Parent, a
registration statement on Form S-8 for the shares of Parent Common Stock
issuable with respect to assumed Company Stock Options as soon as is reasonably
practicable after the Effective Time and intends to maintain the effectiveness
of such registration statement thereafter for so long as any of such options or
other rights remain outstanding.

     5.11  Indemnification.

        (a) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to any indemnification agreements between the Company and its directors
and officers as of the Effective Time (the "INDEMNIFIED PARTIES"). The Articles
of Incorporation and Bylaws of the Surviving Corporation will contain provisions
with respect to exculpation and indemnification that are at least as favorable
to the Indemnified Parties as those contained in the Articles of Incorporation
and Bylaws of the Company as in effect on the date hereof, which provisions will
not be amended, repealed or otherwise modified for a period of six years from
the Effective Time in any manner that would adversely affect the rights
thereunder of individuals who were directors, officers, employees or agents of
the Company, unless such modification is required by law.

        (b) For a period of six years after the Effective Time, Parent will
cause the Surviving Corporation to use its commercially reasonable efforts to
maintain in effect, if available, directors' and officers' liability insurance
covering those persons who are currently covered by the Company's directors' and
officers' liability insurance policy on terms comparable to those applicable to
the current directors and officers of the Company; provided, however, that in no
event will Parent or the Surviving Corporation be required to expend an annual
premium for such coverage in excess of $225,000 (or such coverage as is
available for such annual premium).

     5.12  Board of Directors of Combined Company. The Board of Directors of
Parent will take all actions necessary to cause the Parent's Board of Directors,
immediately after the Effective Time, to consist of nine persons, four of whom
shall have been designated by the Board of Directors of the Company prior to the
Effective Time (including Jeffrey T. Arnold) and four of whom shall have been
designated by the Board of Directors of Parent immediately prior to the
Effective Time (including W. Michael Long). In addition, Parent and the Company
by mutual agreement shall specify an additional person to serve on Parent's
Board of Directors effective immediately after the Effective Time. If, prior to
the Effective Time, any of the designees of Parent or the Company shall decline
or be unable to serve as a director of Parent immediately after the Merger,
Parent (if such person was designated by Parent) or the Company (if such person
was designated by the Company) shall designate another person to serve in such
person's stead.

     5.13  Officers of the Combined Company. At the Effective Time W. Michael
Long will be offered a position as Chairman of the Board of Parent and Chief
Operating Officer and Jeffrey T. Arnold will be offered a position as Chief
Executive Officer of Parent.

     5.14  Change of Name; Increase of Authorized Shares. Subject to the terms
hereof, at the Parent Stockholders Meeting, Parent shall propose and recommend
that its Certificate of Incorporation be amended at the Effective Time to change
its name to a name mutually agreeable to the Company and Parent. In addition, at
the Parent Stockholder Meeting, Parent shall propose and recommend that its

                                      -41-
<PAGE>   430

Certificate of Incorporation be amended to increase the authorized number of
shares of Parent Common Stock thereunder to 450,000,000 shares and that the
authorized number of shares of Preferred Stock of Parent be increased to
10,000,000 shares, provided that Parent may propose and recommend an increase of
such lesser number as in good faith it determines (provided that, subject to the
terms hereof, such lesser number is not less than the number of shares required
to be issued or reserved for issuance by virtue of the Merger and the other
transactions contemplated hereby).

     5.15  Headquarters of Combined Company. Immediately after the Effective
Time the headquarters of Parent and the Company shall be jointly located in
Atlanta, Georgia.

     5.16  Branding. Immediately after the Effective Time of the Merger Parent
and the Surviving Corporation shall adopt WebMD as the brand name of Parent's
and the Surviving Corporation's products and services.

     5.17  Nasdaq Listing. Parent agrees to use its commercially reasonable
efforts to authorize for listing on Nasdaq the shares of Parent Common Stock
issuable, and those required to be reserved for issuance, in connection with the
Merger, upon official notice of issuance.

     5.18  Company Affiliate Agreement. Not later than 30 days prior to the
Company Stockholders' Meeting, the Company shall deliver to Parent a list of
those persons who may be deemed to be, in the Company's reasonable judgment,
affiliates of the Company within the meaning of Rule 145 promulgated under the
Securities Act (each a "COMPANY AFFILIATE"). The Company will provide Parent
with such information and documents as Parent reasonably requests for purposes
of reviewing such list. Parent will be entitled to place appropriate legends
with respect to the restrictions imposed by Rule 145 promulgated under the
Securities Act on the certificates evidencing any Parent Common Stock to be
received by a Company Affiliate pursuant to the terms of this Agreement, and, in
the reasonable judgment of Parent, to issue appropriate stop transfer
instructions to the transfer agent for the Parent Common Stock.

     5.19  Comfort Letters. At the request of Parent, the Company shall cause
its Ernst & Young LLP, certified public accountants to Company, to deliver a
comfort letter, in form and substance reasonably satisfactory to Parent, with
respect to financial information relating to the Company included in the
Registration Statement. At the request of the Company, Parent shall cause Ernst
& Young LLP, certified public accountants to Parent, to deliver a comfort letter
in form and substance reasonably satisfactory to Company, with respect to
financial information relating to the Parent included in the Registration
Statement.

     5.20  Stockholder Agreements. Except for the registration rights
arrangements described in the Company Schedules and except for rights described
in Part 6.2(h) of the Company Schedules, prior to the Effective Time the Company
shall use commercially reasonable efforts to terminate all material rights of a
stockholder and obligations of the Company under any stockholder or other
agreement entered into between the Company and the stockholder of the Company in
its capacity as a stockholder (and not as a provider of goods and services),
including, without limitation, rights of first refusal and information rights,
other than dissenter rights and the rights of the Company Capital Stock to
receive shares of Parent Common Stock in the Merger.

     5.21  FIRPTA Compliance. On or prior to the Closing Date, the Company shall
deliver to Parent a properly executed statement that the shares of Company
Capital Stock do not constitute "U.S. real property interests," as defined in
Section 897(c) of the Code. Such statement shall be in a form reasonably
acceptable to Parent and in accordance with the requirements of Treasury
Regulation Section 1.897-2(h), for purposes of satisfying Parent's obligations
under Treasury Regulation Section 1.1445-2(c)(3). In addition, simultaneously
with delivery of such statement, the Company shall provide to Parent, as agent
for the Company, a form of notice to the Internal Revenue Service in accordance
with the requirements of Treasury Regulation Section 1.897-2(h), along with
written authorization for Parent to deliver such form of notice to the Internal
Revenue Service on behalf of the Company upon the Closing.

     5.22  Additional Stockholder Vote. The Company shall seek approval by the
requisite vote of its stockholders of the acceleration of stock options under
the Company Stock Option Plans as a result of the consummation of the Merger
that may be deemed to constitute "parachute payments" pursuant to Section 280(G)
of the Code, such that if such approval is obtained, all such accelerated
vesting resulting from the transactions contemplated hereby would not be deemed
to be "parachute payments" pursuant to Section 280(G) of the Code or would be
exempt from such treatment under Section 280(G) of the Code with respect to the
holders who have agreed to waive such acceleration in the absence of obtaining
such requisite vote.

                      AGREEMENT AND PLAN OF REORGANIZATION

     This AGREEMENT AND PLAN OF REORGANIZATION is made and entered into as of
April 20, 1999, among Healtheon Corporation, a Delaware corporation ("PARENT"),
Merc Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of
Parent ("MERGER SUB"), and MedE America Corporation, a Delaware corporation (the
"COMPANY").

                                    RECITALS

     A. Upon the terms and subject to the conditions of this Agreement and in
accordance with the Delaware General Corporation Law ("DELAWARE LAW"), Parent,
Merger Sub and the Company intend to enter into a business combination
transaction.

     B. The Board of Directors of the Company (the "COMPANY BOARD") (i) has
determined that the Merger (as defined in Section 1.1) is consistent with and in
furtherance of the long-term business strategy of the Company and fair to, and
in the best interests of, the Company and its stockholders, (ii) has approved
this Agreement, the Merger and the other transactions contemplated by this
Agreement and (iii) has determined to recommend that the stockholders of the
Company adopt and approve this Agreement and approve the Merger.

     C. The Board of Directors of Parent (i) has determined that the Merger (as
defined in Section 1.1) is consistent with and in furtherance of the long-term
business strategy of Parent and fair to, and in the best interests of, Parent
and its stockholders and (ii) has approved this Agreement, the Merger and the
other transactions contemplated by this Agreement.

     D. Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, certain
stockholders of the Company are entering into Voting Agreements in substantially
the form attached hereto as Exhibit A (the "COMPANY VOTING AGREEMENTS").

     E. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "CODE").

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties agree
as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1  The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of Delaware Law, Merger Sub shall be merged with and into
the Company (the "MERGER"), the separate corporate existence of Merger Sub shall
cease and the Company shall continue as the surviving corporation. The Company
as the surviving corporation after the Merger is hereinafter sometimes referred
to as the "SURVIVING CORPORATION".

     1.2  Effective Time; Closing. Subject to the provisions of this Agreement,
the parties hereto shall cause the Merger to be consummated by filing a
Certificate of Merger with the Secretary of State of the State of Delaware in
accordance with the relevant provisions of Delaware Law (the "CERTIFICATE OF
MERGER") (the time of such filing with the Secretary of State of the State of
Delaware (or such later time as may be agreed in writing by the Company and
Parent and specified in the Certificate of Merger) being the "EFFECTIVE TIME")
as soon as practicable on or after the Closing Date (as herein defined). Unless
the context otherwise requires, the term "AGREEMENT" as used herein refers

take place at the offices of Wilson Sonsini Goodrich & Rosati, Professional
Corporation, at a time and date to be specified by the parties, which shall be
no later than the second business day after the satisfaction or waiver of the
conditions set forth in Article VI, or at such other time, date and location as
the parties hereto agree in writing (the "CLOSING DATE").

     1.3  Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement and the applicable provisions of Delaware
Law. Without limiting the generality of the foregoing, and subject thereto, at
the Effective Time all the property, rights, privileges, powers and franchises
of the Company and Merger Sub shall vest in the Surviving Corporation, and all
debts, liabilities and duties of the Company and Merger Sub shall become the
debts, liabilities and duties of the Surviving Corporation.

     1.4  Certificate of Incorporation; Bylaws.

        (a) At the Effective Time, the Certificate of Incorporation of Merger
Sub, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation of the
Surviving Corporation; provided, however, that at the Effective Time the
Certificate of Incorporation of the Surviving Corporation shall be amended so
that the name of the Surviving Corporation shall be "MedE America Corporation."

        (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be, at the Effective Time, the Bylaws of the Surviving
Corporation until thereafter amended.

     1.5  Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time, until their
respective successors are duly appointed.

     1.6  Effect on Capital Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, the Company or the
holders of any of the following securities, the following shall occur:

        (a) Conversion of Company Common Stock. Subject to the provisions of
Section 1.6(f) below, each share of Common Stock of the Company ("COMPANY COMMON
STOCK") issued and outstanding immediately prior to the Effective Time, other
than any shares of the Company Common Stock to be canceled pursuant to Section
1.6(b), will be canceled and extinguished and automatically converted into the
right to receive that number of shares of Parent Common Stock equal to .6593
(the "EXCHANGE RATIO") upon surrender of the certificate representing such share
of the Company Common Stock in the manner provided in Section 1.7 (or in the
case of a lost, stolen or destroyed certificate, upon delivery of an affidavit
(and bond, if required) in the manner provided in Section 1.9). If any shares of
Company Common Stock outstanding immediately prior to the Effective Time are
unvested or are subject to a repurchase option, risk of forfeiture or other
condition under any applicable restricted stock purchase agreement or other
agreement with the Company, then the shares of Parent Common Stock issued in
exchange for such shares of Company Common Stock will also be unvested to the
same extent and subject to the same repurchase option, risk of forfeiture or
other condition, as applicable, and the certificates representing such shares of
Parent Common Stock may accordingly be marked with appropriate legends. The
Company shall take all action that may be necessary to ensure that, from and
after the Effective Time, Parent is entitled to exercise any such repurchase
option or other right set forth in any such restricted stock purchase agreement
or other agreement.

        (b) Cancellation of Parent-Owned Stock. Each share of Company Common
Stock held by the Company or owned by Merger Sub, Parent or any direct or
indirect wholly-owned subsidiary of the Company or of Parent immediately prior
to the Effective Time shall be canceled and extinguished without any conversion
thereof.

<PAGE>   445

        (c) Stock Options; Employee Stock Purchase Plans; Warrants.

           (i) At the Effective Time, all options to purchase Company Common
Stock then outstanding under the Company's Stock Option and Restricted Stock
Purchase Plan and the Company's 1998 Stock Option and Restricted Stock Purchase
Plan (the "COMPANY STOCK OPTION PLANS") shall be assumed by Parent in accordance
with Section 5.8 hereof. Rights outstanding under the Company's 1998 Employee
Stock Purchase Plan (the "COMPANY PURCHASE PLAN") shall be treated as set forth
in Article V hereof.

           (ii) At the Effective Time, the warrants issued by the Company and
set forth on Part 2.2 of the Company Schedules (which warrants entitle the
holders thereof as set forth on such Part 2.2 to purchase the number of shares
of Company Common Stock set forth on such Part 2.2) (collectively, the
"WARRANTS") shall be, subject to Section 5.8 hereof, either exercised or
terminated prior to the Effective Time or converted into Parent Common Stock as
of the Effective Time. Part 2.2 of the Company Schedules describes, with respect
to each warrant outstanding, the number of shares of Company Common Stock into
which such warrant may be exercised, the exercise price, the name of the holder
of record, the termination date, whether such warrant has registration rights,
and, if applicable, a complete description of such registration rights.

        (d) Capital Stock of Merger Sub. Each share of Common Stock of Merger
Sub (the "MERGER SUB COMMON STOCK") issued and outstanding immediately prior to
the Effective Time shall be converted into one validly issued, fully paid and
nonassessable share of Common Stock of the Surviving Corporation. Each
certificate evidencing ownership of shares of Merger Sub Common Stock shall
evidence ownership of such shares of capital stock of the Surviving Corporation.

        (e) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued by virtue of the Merger, but in lieu thereof each holder of
shares of Company Common Stock who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall, upon
surrender of such holder's Certificate(s) (as defined in Section 1.7(c)),
receive from Parent an amount of cash (rounded to the nearest whole cent),
without interest, equal to the product of (i) such fraction, multiplied by (ii)
the average closing price of one share of Parent Common Stock for the ten (10)
most recent days that Parent Common Stock has traded ending on the trading day
ending one day prior to the Closing Date, as reported on the Nasdaq National
Market System ("NASDAQ").

        (f) Adjustments to Exchange Ratio.

           (i) The Exchange Ratio shall be adjusted to reflect appropriately the
effect of any stock split, reverse stock split, stock dividend (including any
dividend or distribution of securities convertible into Parent Common Stock or
Company Common Stock), reorganization, recapitalization, reclassification or
other like change with respect to Parent Common Stock or Company Common Stock
occurring on or after the date hereof and prior to the Effective Time.

           (ii) In the event that the 10 day average closing price for Parent's
Common Stock (as reported on Nasdaq) for the period ending two days prior to the
date of the Company Stockholders' Meeting (the "MEETING PRICE") is less than
$38.68, then Parent may, in its sole discretion and no later than 24 hours prior
to the Stockholders Meeting, change the Exchange Ratio to a ratio equal to
$25.50 divided by the Meeting Price. In the event that the Meeting Price is less
than $38.68 and Parent does not exercise its right to change the Exchange Ratio,
then the Company may exercise its right to terminate the Agreement as provided
for in Section 7.1(h) hereof.

           (iii) In the event that the Meeting Price is more than $63.70, then
the Company may, in its sole discretion and no later than 24 hours prior to the
Company Stockholders' Meeting, change the Exchange Ratio to a ratio equal to $42
divided by the Meeting Price. In the event that the Meeting Price is more than
$63.70 and the Company does not exercise its right to change the Exchange Ratio,
then Parent may exercise its right to terminate the Agreement as provided for in
Section 7.1(i) hereof.

     1.7  Surrender of Certificates.

        (a) Exchange Agent. American Stock Transfer & Trust Company, Parent's
Transfer Agent, shall act as the exchange agent (the "EXCHANGE AGENT") in the
Merger.

        (b) Parent to Provide Common Stock. Promptly after the Effective Time,
Parent shall make available to the Exchange Agent for exchange in accordance
with this Article I, the shares of Parent Common Stock issuable pursuant to
Section 1.6 in exchange for outstanding shares of Company Common Stock, and cash
in an amount sufficient for payment in lieu of fractional shares pursuant to
Section 1.6(e) and any dividends or distributions which holders of shares of
Company Common Stock may be entitled pursuant to Section 1.7(d).

        (c) Exchange Procedures. Promptly after the Effective Time, Parent shall
cause the Exchange Agent to mail to each holder of record (as of the Effective
Time) of a certificate or certificates (the "CERTIFICATES") which immediately
prior to the Effective Time represented outstanding shares of Company Common
Stock whose shares were converted into the right to receive shares of Parent
Common Stock pursuant to Section 1.6, cash in lieu of any fractional shares
pursuant to Section 1.6(e) and any dividends or other distributions pursuant to
Section 1.7(d), (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Parent Common Stock, cash in
lieu of any fractional shares pursuant to Section 1.6(e) and any dividends or
other distributions pursuant to Section 1.7(d). Upon surrender of Certificates
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, the holders of
such Certificates shall be entitled to receive in exchange therefor certificates
representing the number of whole shares of Parent Common Stock into which their
shares of Company Common Stock were converted at the Effective Time, payment in
lieu of fractional shares which such holders have the right to receive pursuant
to Section 1.6(e) and any dividends or distributions payable pursuant to Section
1.7(d), and the Certificates so surrendered shall forthwith be canceled. Until
so surrendered, outstanding Certificates will be deemed from and after the
Effective Time, for all corporate purposes, subject to Section 1.7(d) as to the
payment of dividends, to evidence the ownership of the number of full shares of
Parent Common Stock into which such shares of Company Common Stock shall have
been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 1.6(e) and any
dividends or distributions payable pursuant to Section 1.7(d).

        (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holders of any unsurrendered Certificates with respect to the
shares of Parent Common Stock represented thereby until the holders of record of
such Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the record holders thereof, without interest, certificates representing whole
shares of Parent Common Stock issued in exchange therefor along with payment in
lieu of fractional shares pursuant to Section 1.6(e) hereof and the amount of
any such dividends or other distributions with a record date after the Effective
Time payable with respect to such whole shares of Parent Common Stock.

        (e) Transfers of Ownership. If certificates for shares of Parent Common
Stock are to be issued in a name other than that in which the Certificates
surrendered in exchange therefor are registered, it will be a condition of the
issuance thereof that the Certificates so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the persons requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of certificates for shares of
Parent Common Stock in any name other than that of the registered holder of the

                                       -4-
<PAGE>   447

Certificates surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

        (f) Required Withholding. Each of the Exchange Agent, Parent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign tax law or under any other applicable Legal Requirement
(as defined in Section 2.2). To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the person to whom such amounts would otherwise have been
paid.

        (g) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, Parent, the Surviving Corporation nor
any party hereto shall be liable to a holder of shares of Parent Common Stock or
Company Common Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

     1.8  No Further Ownership Rights in Company Common Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Common Stock in accordance with the terms hereof (including any cash paid in
respect thereof pursuant to Section 1.6(e) and 1.7(d)) shall be deemed to have
been issued in full satisfaction of all rights pertaining to such shares of
Company Common Stock, and there shall be no further registration of transfers on
the records of the Surviving Corporation of shares of Company Common Stock which
were outstanding immediately prior to the Effective Time. If after the Effective
Time Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

     1.9  Lost, Stolen or Destroyed Certificates. In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, certificates representing the
shares of Parent Common Stock into which the shares of Company Common Stock
represented by such Certificates were converted pursuant to Section 1.6, cash
for fractional shares, if any, as may be required pursuant to Section 1.6(e) and
any dividends or distributions payable pursuant to Section 1.7(d); provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

     1.10  Tax Consequences. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code. The parties hereto adopt this Agreement as a "plan of reorganization"
within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
Income Tax Regulations.

     1.11  Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub will take all such lawful and necessary action, so long
as such action is consistent with this Agreement.

would have a Material Adverse Effect (as defined in Section 8.3) on the Company.

        (d) The Company has delivered or made available to Parent a true and
correct copy of the Certificate of Incorporation and Bylaws of the Company and
similar governing instruments of each of its subsidiaries, each as amended to

     2.4  Authority; Non-Contravention.

        (a) The Company has all requisite corporate power and authority to enter
into this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company, subject only to the approval and
adoption of this Agreement and the approval of the Merger by the Company's
stockholders and the filing of the Certificate of Merger pursuant to Delaware
Law. A vote of the holders of a majority of the outstanding shares of the
Company Common Stock is sufficient for the Company's stockholders to approve and
adopt this Agreement and approve the Merger. This Agreement has been duly
executed and delivered by the Company and, assuming due execution and delivery
by Parent and Merger Sub, constitutes valid and binding obligations of the
Company, enforceable against the Company in accordance with its terms, except as
enforceability may be limited by bankruptcy and other similar laws and general
principles of equity. The execution and delivery of this Agreement by the
Company does not, and the performance of this Agreement by the Company will not,
(i) conflict with or violate the Company Charter Documents, (ii) subject to
obtaining the approval and adoption of this Agreement and the approval of the
Merger by the Company's stockholders as contemplated in Section 5.2 and
compliance with the requirements set forth in Section 2.4(b) below, conflict

to the Company or any of its subsidiaries or by which the Company or any of its
subsidiaries or any of their respective properties is bound or affected, or
(iii) except as set forth in Part 2.4(a) of the Company Schedules result in any
material breach of or constitute a material default (or an event that with
notice or lapse of time or both would become a material default) under, or
impair the Company's rights or alter the rights or obligations of any third
party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a material lien or
Encumbrance on any of the material properties or assets of the Company or any of
its subsidiaries pursuant to, any material note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise, concession, or other
instrument or obligation to which the Company or any of its subsidiaries is a
party or by which the Company or any of its subsidiaries or its or any of their
respective assets are bound or affected. Part 2.4(a) of the Company Schedules
lists all consents, waivers and approvals under any of the Company's material
agreements, contracts, licenses or leases required to be obtained in connection
with the consummation of the transactions contemplated hereby, which, if
individually or in the aggregate not obtained, would result in a material loss
of benefits to the Company, Parent or the Surviving Corporation as a result of
the Merger.

        (b) Except as set forth in Part 2.4(b) of the Company Schedules, no
consent, approval, order or authorization of, or registration, declaration or
filing with any court, administrative agency or commission or other governmental
authority or instrumentality, foreign or domestic ("GOVERNMENTAL ENTITY"), is
required to be obtained or made by the Company in connection with the execution
and delivery of this Agreement or the consummation of the Merger, except for (i)
the filing of the Certificate of Merger with the Secretary of State of the State
of Delaware, (ii) the filing of the Prospectus/Proxy Statement (as defined in
Section 2.19) with the Securities and Exchange Commission ("SEC") in accordance

Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), (iii) such
consents, approvals, orders, authorizations, registrations, declarations and
filings as may be required under applicable federal, foreign and state

        (e) The operation of the business of Parent as such business currently

subsidiaries, nor, to Parent's knowledge, has any Governmental Entity indicated
an intention to conduct an investigation of Parent or any of its subsidiaries.

there are no claims, suits, actions or proceedings pending or, to the knowledge
of Parent, threatened against, relating to or affecting Parent or any of its
subsidiaries, before any court, governmental department, commission, agency,
instrumentality or authority, or any arbitrator that seeks to restrain or enjoin
the consummation of the transactions contemplated by this Agreement or which

such claims, actions or proceedings, to be material to Parent. No Governmental
Entity has at any time challenged or questioned in a writing delivered to Parent
the legal right of Parent to design, manufacture, offer or sell any of its
products or services in the present manner or style thereof. As of the date
hereof, to the knowledge of Parent, no event has occurred, and no claim, dispute
or other condition or circumstance exists, that will, or that would reasonably
be expected to, cause or provide a bona fide basis for a director or executive
officer of Parent to seek indemnification from Parent.

under any property, including the land and the improvements, ground water and
surface water thereof, that Parent or any of its subsidiaries has at any time
owned, operated, occupied or leased.

        (b) Hazardous Materials Activities. Except as would not result in a

manufactured, disposed of, released or exposed its employees or others to
Hazardous Materials in violation of any law in effect on or before the Closing
Date, and (ii) neither Parent nor any of its subsidiaries has disposed of,

<PAGE>   470

that accommodate same century and multi-century formulas and date values, leap
year recognition and calculations, and date data interface values that reflect
the century. Parent's products and internal systems manage and manipulate data
involving dates and times, including single century formulas and multi-century
formulas, and do not cause an abnormal ending scenario within the application or
generate incorrect values or invalid results involving such dates.

     3.15  Agreements, Contracts and Commitments. As of the date of this
Agreement, neither Parent nor any of its subsidiaries, nor to Parent's knowledge
any other party to a material Contract of Parent, is in breach, violation or
default under, and neither Parent nor any of its subsidiaries has received
written notice that it has breached, violated or defaulted under, any of the
material terms or conditions of any material Contract of Parent in such a manner
as would permit any other party to cancel or terminate any such material
Contract of Parent, or would permit any other party to seek material damages or
other remedies (for any or all of such breaches, violations or defaults, in the
aggregate).

Parent for inclusion in the Registration Statement will, at the time the
Registration Statement becomes effective under the Securities Act, contain any
untrue statement of a material fact or omit to state any material fact required

respects with the provisions of the Securities Act and the rules and regulations
promulgated by the SEC thereunder, except that no representation or warranty is
made by Parent with respect to statements made or incorporated by reference
therein based on information supplied by the Company for inclusion or
incorporation by reference in the Prospectus/Proxy Statement.

("DOJ") Notification and Report Forms relating to the transactions contemplated

or any other government officials, and/or mailing to stockholders of the Company
and/or Parent, such amendment or supplement.

     5.2  Meeting of Company Stockholders.

        (a) Promptly after the date hereof, the Company will take all action
necessary in accordance with Delaware Law and its Certificate of Incorporation
and Bylaws to convene a meeting of the Company's stockholders to consider
adoption and approval of this Agreement and approval of the Merger (the "COMPANY
STOCKHOLDERS' MEETING") to be held as promptly as practicable, and in any event
(to the extent permissible under applicable law) within 45 days after the
declaration of effectiveness of the Registration Statement. Subject to Section
5.2(c) hereof, the Company will use its commercially reasonable efforts to
solicit from its stockholders proxies in favor of the adoption and approval of
this Agreement and the approval of the Merger and will take all other action
necessary or advisable to secure the vote or consent of its stockholders
required by the rules of Nasdaq or Delaware Law to obtain such approvals.
Notwithstanding anything to the contrary contained in this Agreement, the
Company may adjourn or postpone the Company Stockholders' Meeting to the extent
necessary to ensure that any necessary supplement or amendment to the
Prospectus/Proxy Statement is provided to the Company's stockholders in advance
of a vote on the Merger and this Agreement or, if as of the time for which the
Company Stockholders' Meeting is originally scheduled (as set forth in the
Prospectus/Proxy Statement) there are insufficient shares of Company Common
Stock represented (either in person or by proxy) to constitute a quorum
necessary to conduct the business of the Company's Stockholders' Meeting. The
Company shall ensure that the Company Stockholders' Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited by the Company in
connection with the Company Stockholders' Meeting are solicited, in compliance
with the Delaware Law, the Company's Certificate of Incorporation and Bylaws,
the rules of Nasdaq and all other applicable legal requirements. The Company's
obligation to call, give notice of, convene and hold the Company Stockholders'
Meeting in accordance with this Section 5.2(a) shall not be limited to or
otherwise affected by the commencement, disclosure,

announcement or submission to the Company of any Acquisition Proposal (as
defined in Section 5.4(a)), or by any withdrawal, amendment or modification of
the recommendation of the Company Board with respect to the Merger and/or this
Agreement; provided, however, if the Company terminates this Agreement pursuant
to Section 7.1(j) hereof, the Company not be obligated to convene and hold the
Company Stockholders' Meeting.

        (b) Subject to Section 5.2(c) below: (i) the Company Board shall
unanimously recommend that the Company's stockholders vote in favor of and adopt
and approve this Agreement and approve the Merger at the Company Stockholders'
Meeting; (ii) the Prospectus/Proxy Statement shall include a statement to the
effect that the Company Board has unanimously recommended that the Company's
stockholders vote in favor of and adopt and approve this Agreement and the
Merger at the Company Stockholders' Meeting; and (iii) neither the Company Board
nor any committee thereof shall withdraw, amend or modify, or propose or resolve
to withdraw, amend or modify in a manner adverse to Parent, the unanimous
recommendation of the Company Board that the Company's stockholders vote in
favor of and adopt and approve this Agreement and the Merger.

        (c) Nothing in this Agreement shall prevent the Company Board from
withholding, withdrawing, amending or modifying its unanimous recommendation in
favor of the Merger if (i) a Superior Offer (as defined below) is made to the
Company and is not withdrawn, (ii) the Company shall have provided written
notice to Parent (a "NOTICE OF SUPERIOR OFFER") advising Parent that the Company
has received a Superior Offer, specifying the material terms and conditions of
such Superior Offer and identifying the person or entity making such Superior
Offer, (iii) Parent shall not have, within five (5) business days of Parent's
receipt of the Notice of Superior Proposal, made an offer that the Company Board
by a majority vote determines in its good faith judgment (after consultation
with a financial adviser of nationally recognized reputation) to be at least as
favorable to the Company's stockholders as such Superior Proposal (it being
agreed that the Company Board shall convene a meeting to consider any such offer
by Parent promptly following the receipt thereof), (iv) the Company Board
concludes in good faith, after consultation with its outside counsel, that, in
light of such Superior Offer, the withholding, withdrawal, amendment or
modification of such recommendation is required in order for the Company Board
to comply with its fiduciary obligations to the Company's stockholders under
applicable law and (v) neither the Company nor any of its representatives shall
have violated any of the restrictions set forth in Section 5.4 or this Section
5.2. The Company shall provide Parent with at least three business days prior
notice (or such lesser prior notice as provided to the members of the Company's
Board but in no event less than twenty-four hours) of any meeting of the
Company's Board at which the Company's Board is reasonably expected to consider
any Acquisition Transaction (as defined below).

     For purposes of this Agreement "SUPERIOR OFFER" shall mean an unsolicited,
bona fide written offer made by a third party (other than any current
stockholder of the Company who as of the date of this Agreement holds more than
5% of the Company's capital stock) to consummate any of the following
transactions: (i) a merger or consolidation involving the Company pursuant to
which the stockholders of the Company immediately preceding such transaction
hold less than 50% of the equity interest in the surviving or resulting entity
of such transaction, (ii) a sale or other disposition by Company of assets
(excluding inventory and used equipment sold in the ordinary course of business)
representing in excess of 85% of the fair market value of Company's business
immediately prior to such sale or (iii) the acquisition by any person or group
(including by way of a tender offer or an exchange offer), directly or
indirectly, of ownership of 85% of the then outstanding shares of capital stock
of the Company, on terms that the Company Board determines, in its reasonable
judgment (after consultation with a financial adviser of nationally recognized
reputation) and without violating the provisions of Section 5.4 below to be more
favorable to the Company stockholders than the terms of the Merger.

        (d) Nothing contained in this Agreement shall prohibit the Company or
the Company Board from taking and disclosing to its stockholders a position
contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act.

     5.3  Confidentiality; Access to Information.

        (a) The parties acknowledge that the Company and Parent have previously
executed a Confidentiality Agreement, dated as of April 1, 1999 (the
"CONFIDENTIALITY AGREEMENT"), which Confidentiality Agreement will continue in
full force and effect in accordance with its terms.

        (b) Access to Information. The parties will afford to each other and
their respective accountants, counsel and other representatives reasonable
access during normal business hours to their respective properties, books,
records and personnel during the period prior to the Effective Time to obtain
all information concerning the business, including the status of product
development efforts, properties, results of operations and personnel of the
Company, as the other party may reasonably request. No information or knowledge
obtained by either party in any investigation pursuant to this Section 5.3 will
affect or be deemed to modify any representation or warranty contained herein or
the conditions to the obligations of the parties to consummate the Merger.

     5.4  No Solicitation.

        (a) From and after the date of this Agreement until the Effective Time
or termination of this Agreement pursuant to Article VII, the Company and its
subsidiaries will not, nor will they authorize or permit any of their respective
officers, directors, affiliates or employees or any investment banker, attorney
or other advisor or representative retained by any of them to, directly or
indirectly, (i) solicit, initiate, encourage or induce the making, submission or
announcement of any Acquisition Proposal (as hereinafter defined), (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes or may
reasonably be expected to lead to, any Acquisition Proposal, (iii) engage in
discussions with any person with respect to any Acquisition Proposal, except as
to the existence of these provisions, (iv) approve, endorse or recommend any
Acquisition Proposal or (v) enter into any letter of intent or similar document
or any contract agreement or commitment contemplating or otherwise relating to
any Acquisition Transaction. Notwithstanding the foregoing, the Company may
(either directly or indirectly through its advisors or other intermediaries) (i)
furnish information regarding the Company and its businesses, properties,
operations and assets to a third party that has made an unsolicited written bona
fide Superior Offer prior to the Company Stockholders' Meeting; (ii) engage in
discussions or negotiations with such a third party relating to such Superior
Offer; and (iii) take any action required to be taken by the Company pursuant to
an order issued and not reversed, withdrawn or stayed by any court of competent
jurisdiction, provided, that, in each case only to the extent that: (A) the
Board of Directors of the Company shall have concluded in good faith on the
basis of written advice from outside counsel that such action is necessary in
order to comply with the fiduciary obligations of the Board of Directors under
applicable law; (B) neither the Company nor any representative of the Company
shall have violated any of the restrictions set forth in this Section 5.4; (C)
prior to furnishing such nonpublic information to, or entering into discussions
or negotiations with, such person or group, the Company gives Parent written
notice of the identity of such person or group and of the Company's intention to
furnish nonpublic information to, or enter into discussions or negotiations
with, such person or group and the Company receives from such person or group an
executed confidentiality agreement which shall be no less favorable to the
Company than the Confidentiality Agreement; and (D) contemporaneously with
furnishing any such nonpublic information to such person or group, the Company
furnishes such nonpublic information to Parent (to the extent such nonpublic
information has not been previously furnished by the Company to Parent). The
Company and its subsidiaries will immediately cease any and all existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any Acquisition Proposal. Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in the preceding two
sentences by any officer, director or employee of the Company or any of its
subsidiaries or any investment banker, attorney or other advisor or
representative of the Company or any of its subsidiaries shall be deemed to be a
breach of this Section 5.4 by the Company.

     For purposes of this Agreement, "ACQUISITION PROPOSAL" shall mean any offer
or proposal (other than an offer or proposal by Parent) relating to any
Acquisition Transaction. For purposes of this Agreement,

                                      -33-
<PAGE>   476

"ACQUISITION TRANSACTION" shall mean any transaction or series of related
transactions involving: (A) any purchase from the Company or acquisition by any
person or "group" (as defined under Section 13(d) of the Exchange Act and the
rules and regulations thereunder) of more than a 5% interest in the total
outstanding voting securities of the Company or any of its subsidiaries or any
tender offer or exchange offer that if consummated would result in any person or
"group" (as defined under Section 13(d) of the Exchange Act and the rules and
regulations thereunder) beneficially owning 5% or more of the total outstanding
voting securities of the Company or any of its subsidiaries or any merger,
consolidation, business combination or similar transaction involving the
Company; (B) any sale, lease (other than in the ordinary course of business),
exchange, transfer, license (other than in the ordinary course of business),
acquisition or disposition of more than 5% of the assets of the Company; or (C)
any liquidation or dissolution of the Company.

        (b) In addition to the obligations of the Company set forth in paragraph
(a) of this Section 5.4, the Company as promptly as practicable shall advise
Parent orally and in writing of any request for non-public information which the
Company reasonably believes would lead to an Acquisition Proposal or to any
Acquisition Transaction, or any inquiry with respect to or which the Company
reasonably should believe would lead to any Acquisition Proposal, the material
terms and conditions of such request, Acquisition Proposal or inquiry, and the
identity of the person or group making any such request, Acquisition Proposal or
inquiry. The Company will, consistent with the fiduciary duties of the Company's
Board, keep Parent informed as promptly as practicable in all material respects
of the status and details (including material amendments or proposed material
amendments) of any such request, Acquisition Proposal or inquiry.

     5.5  Public Disclosure. Parent and the Company will attempt to consult with
each other, and to the extent practicable, agree, before issuing any press
release or otherwise making any public statement with respect to the Merger,
this Agreement or any Acquisition Proposal and will not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by law or any listing agreement with a national securities
exchange. The parties have agreed to the text of the joint press release
announcing the signing of this Agreement.

     5.6  Reasonable Efforts; Notification.

        (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Merger and the other transactions contemplated by this
Agreement, including using reasonable efforts to accomplish the following: (i)
the taking of all reasonable acts necessary to cause the conditions precedent
set forth in Article VI to be satisfied, (ii) the obtaining of all necessary
actions or nonactions, waivers, consents, approvals, orders and authorizations
from Governmental Entities and the making of all necessary registrations,
declarations and filings (including registrations, declarations and filings with
Governmental Entities, if any) and the taking of all reasonable steps as may be
necessary to avoid any suit, claim, action, investigation or proceeding by any
Governmental Entity, (iii) the obtaining of all necessary consents, approvals or
waivers from third parties, (iv) the defending of any suits, claims, actions,
investigations or proceedings, whether judicial or administrative, challenging
this Agreement or the consummation of the transactions contemplated hereby,
including seeking to have any stay or temporary restraining order entered by any
court or other Governmental Entity vacated or reversed and (v) the execution or
delivery of any additional instruments necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, this Agreement. In
connection with and without limiting the foregoing, the Company and the Company
Board shall, if any state takeover statute or similar statute or regulation is
or becomes applicable to the Merger, this Agreement or any of the transactions
contemplated by this Agreement, use all reasonable efforts to ensure that the
Merger and the other transactions contemplated by this Agreement may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the effect of such statute or regulation on
the Merger, this Agreement and the transactions contemplated hereby.
Notwithstanding anything herein to the contrary,
                                      -34-
<PAGE>   477

nothing in this Agreement shall be deemed to require Parent or the Company or
any subsidiary or affiliate thereof to agree to any divestiture by itself or any
of its affiliates of shares of capital stock or of any material business, assets
or property, or the imposition of any material limitation on the ability of any
of them to conduct their businesses or to own or exercise control of such
assets, properties and stock.

        (b) The Company shall give prompt notice to Parent of any representation
or warranty made by it contained in this Agreement becoming untrue or
inaccurate, or any failure of the Company to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Section 6.3(a) or 6.3(b) would not be satisfied, provided, however,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

        (c) Parent shall give prompt notice to the Company of any representation
or warranty made by it or Merger Sub contained in this Agreement becoming untrue
or inaccurate, or any failure of Parent or Merger Sub to comply with or satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement, in each case, such that the conditions
set forth in Section 6.2(a) or 6.2(b) would not be satisfied, provided, however,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

     5.7  Third Party Consents. As soon as practicable following the date
hereof, Parent and the Company will each use its commercially reasonable efforts
to obtain any consents, waivers and approvals under any of its or its
subsidiaries' respective agreements, contracts, licenses or leases required to
be obtained in connection with the consummation of the transactions contemplated
hereby.

     5.8  Stock Options; Warrants and Employee Benefits.

        (a) At the Effective Time, each outstanding Company Option, whether or
not exercisable and regardless of the respective exercise prices thereof, will
be assumed by Parent. Each Company Option so assumed by Parent under this
Agreement will continue to have, and be subject to, the same terms and
conditions set forth in the applicable Company Stock Option Plan and the related
option agreement immediately prior to the Effective Time (including, without
limitation, any repurchase rights or vesting provisions), except that (i) each
Company Option will be exercisable (or will become exercisable in accordance
with its terms) for that number of whole shares of Parent Common Stock equal to
the product of the number of shares of Company Common Stock that were issuable
upon exercise of such Company Option immediately prior to the Effective Time
multiplied by the Exchange Ratio, rounded down to the nearest whole number of
shares of Parent Common Stock and (ii) the per share exercise price for the
shares of Parent Common Stock issuable upon exercise of such assumed Company
Option will be equal to the quotient determined by dividing the exercise price
per share of Company Common Stock at which such Company Option was exercisable
immediately prior to the Effective Time by the Exchange Ratio, rounded up to the
nearest whole cent.

        (b) It is intended that Company Options assumed by Parent shall qualify
following the Effective Time as incentive stock options as defined in Section
422 of the Code to the extent Company Options qualified as incentive stock
options immediately prior to the Effective Time and the provisions of this
Section 5.8 shall be applied consistent with such intent.

        (c) Other than as specifically provided for in this Section 5.8, as soon
as practicable after the execution of this Agreement, the Company and Parent
shall confer and work together in good faith to agree upon mutually acceptable
employee benefit and compensation arrangements (and terminate the Company
Purchase Plan immediately prior to the Effective Time, if appropriate) so as to
provide benefits to the Company employees generally equivalent in the aggregate
to those provided to similarly situated employees of Parent.

        (d) To the extent that the Warrants are not exercised, converted or
terminated concurrently with or prior to the Effective Time, at the Effective
Time, the Warrants will be assumed by Parent. Each
                                      -35-
<PAGE>   478

Warrant so assumed by Parent under this Agreement will continue to have, and be
subject to, the same terms and conditions set forth in the applicable warrant
agreement immediately prior to the Effective Time (including, without
limitation, any repurchase rights or vesting provisions), except that (i) each
Warrant will be exercisable (or will become exercisable in accordance with its
terms) for that number of whole shares of Parent Common Stock equal to the
product of the number of share of Company Common Stock that were issuable upon
exercise of such Warrant immediately prior to the Effective Time multiplied by
the Exchange Ratio, rounded down to the nearest whole number of shares of Parent
Common Stock and (ii) the per share exercise price for the share of Parent
Common Stock issuable upon exercise of such assumed Warrant will be equal to the
quotient determined by dividing the exercise price per share of Company Common
Stock at which such Warrant was exercisable immediately prior to the Effective
Time by the Exchange Ratio, rounded up to the nearest whole cent.

        (e) Prior to the Closing Date, Parent shall establish an employee stock
option plan substantially similar to the plans currently used to grant Parent
Options pursuant to which, following the Effective Time, Parent will grant stock
options to purchase an aggregate of 700,000 shares of Parent's Common Stock to
employees of the Company. The names of such employees and the number of options
to be granted to each employee will be determined prior to the Closing Date. All
such options shall have an exercise price equal to the closing price (as
reported on Nasdaq) of Parent's Common Stock on the date hereof. Such options
shall vest over a four-year period (25% of the shares thereto shall vest on the
first anniversary of the Closing Date and the remainder in equal monthly
increments thereafter). To the extent legally permissible and subject to
approval by the stockholders of Parent, all options granted pursuant to this
Section 5.8 (e) shall be incentive stock options as defined under Section 422 of
the Code.

        (f) Parent hereby agrees that until December 31, 1999, it shall maintain
the "matching" feature of the Company's 401(k) plan, whereby, subject to certain
restrictions, the Company is obligated to make contributions to an employee's
401(k) account.

        (g) Parent hereby agrees that from the Effective Time until the first
anniversary of the Closing Date, it shall maintain the Company's employee
severance policy.

     5.9  Form S-8. Parent agrees to file a registration statement on Form S-8
for the shares of Parent Common Stock issuable with respect to assumed Company
Stock Options and options granted pursuant to Section 5.8(e) above as soon as is
reasonably practicable after the Effective Time and will use its reasonable best
efforts to maintain the effectiveness of such registration statement thereafter
for so long as any of such options or other rights remain outstanding.

     5.10  Indemnification.

        (a) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to any indemnification agreements between the Company and its directors
and officers as of the Effective Time (the "INDEMNIFIED PARTIES"). The
Certificate of Incorporation and Bylaws of the Surviving Corporation will
contain provisions with respect to exculpation and indemnification that are at
least as favorable to the Indemnified Parties as those contained in the
Certificate of Incorporation and Bylaws of the Company as in effect on the date
hereof, which provisions will not be amended, repealed or otherwise modified for
a period of six years from the Effective Time in any manner that would adversely
affect the rights thereunder of individuals who, immediately prior to the
Effective Time, were directors, officers, employees or agents of the Company,
unless such modification is required by law.

        (b) For a period of three years after the Effective Time, Parent will
cause the Surviving Corporation to use its commercially reasonable efforts to
maintain in effect, if available, directors' and officers' liability insurance
covering those persons who are currently covered by the Company's directors' and
officers' liability insurance policy on terms comparable to those applicable to
the current directors and officers of the Company; provided, however, that in no
event will Parent or the Surviving Corporation be required to expend in excess
of 150% of the annual premium currently paid by the Company for such coverage
(or such coverage as is available for such 150% of such annual premium).

                                      -36-
<PAGE>   479

     5.11  Nasdaq Listing. Parent agrees to authorize for listing on Nasdaq the
shares of Parent Common Stock issuable, and those required to be reserved for
issuance, in connection with the Merger, upon official notice of issuance.

     5.12  Acceleration of Employee Stock Option Vesting. If at any time
following the Effective Time but prior to the date two (2) years following the
Effective Time, (i) Parent shall terminate any employee of the Company without
"cause" (as defined below) or (ii) any employee shall terminate his or her
employment with Parent following a "material reduction in the duties" or
compensation of such employee by Parent or the relocation of such employee to a
location more than 25 miles from such employee's existing work location, without
the employee's consent, Parent shall cause all stock options which were granted
to such employee by the Company prior to the date of this Agreement to become
fully exercisable upon such termination (it being understood that the options to
be granted by Parent pursuant to Section 5.8 hereof are excluded from this
provision). A "material reduction in the duties" of an employee means a
substantive reduction in duties, not a change in title or reporting hierarchy
occurring as a result of the Merger. For purposes of this Section 5.12, "cause"
shall mean (A) the continued poor performance by an employee of his or her
duties following notice and a reasonable period of time to correct such poor
performance; (B) an employee engaging in an act of dishonesty that is materially
and demonstrably injurious to the Company or Parent; or (C) the conviction of an
employee of a felony in respect of a dishonest or fraudulent act or other crime
of moral turpitude.

     5.13  FIRPTA Compliance. On or prior to the Closing Date, the Company shall
deliver to Parent a properly executed statement, in a form reasonably acceptable
to Parent, that the Company Common Stock is not a "U.S. Real Property Interest"
as defined in and in accordance with the requirements of Treasury Regulation
Section 1.897-2(h)(2), for purposes of satisfying Parent's obligations under
Treasury Regulation Section 1.1445-2(c)(3).

     5.14  Board of Directors. As soon as practicable following the Effective
Time and for so long as Welsh, Carson, Anderson & Stowe and William Blair & Co.,
L.L.C. (including such parties affiliated entities) collectively hold at least
25% of the Parent Common Stock issuable to them in the Merger, such entities
shall collectively have the right to nominate one representative to serve on
Parent's Board of Directors.

     5.15  Company Affiliates; Restrictive Legend. Parent will give stop
transfer instructions to its transfer agent with respect to any Parent Common
Stock received pursuant to the Merger by any stockholder of the Company who may
reasonably be deemed to be an affiliate of the Company within the meaning of
Rule 145 promulgated under the Securities Act and there will be placed on the
certificates representing such Parent Common Stock, or any substitutions
therefor, a legend stating in substance:

        "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION
        TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS
        AMENDED, APPLIES AND MAY ONLY BE TRANSFERRED (A) IN CONFORMITY WITH RULE
        145(d) UNDER SUCH ACT, (B) IN ACCORDANCE WITH A WRITTEN OPINION OF
        COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER IN FORM AND SUBSTANCE THAT
        SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF
        1933, AS AMENDED."

        (b) Registration Statement Effective; Proxy Statement. The SEC shall

Kristol, respectively), in form and substance reasonably satisfactory to them,
to the effect that the Merger will constitute a tax-free reorganization within
the meaning of Section 368(a) of the Code and such opinions shall not have been
withdrawn; provided, however, that if the counsel to either Parent or the
Company does not render such opinion, this condition shall nonetheless be deemed
to be satisfied with respect to such party if counsel to the other party renders
such opinion to such party. The parties to this Agreement agree to make such
reasonable representations as requested by such counsel for the purpose of
rendering such opinions.

        (e) Nasdaq Listing. The shares of Parent Common Stock to be issued in

however, such Material Adverse Effect qualification shall be inapplicable with
respect to the representations and warranties contained in Section 3.17, and (B)
for those representations and warranties which address matters only as of a
particular date (which representations shall have been true and correct (subject
to the qualifications set forth in the preceding clause (A)) as of such
particular date) (it being understood that, for purposes of determining the
accuracy of such representations and warranties, any update of or modification
to Parent Schedules made or purported to have been made after the date of this
Agreement shall be disregarded). The Company shall have received a certificate
with respect to the foregoing signed on behalf of Parent by an authorized
officer of Parent.

        (b) Agreements and Covenants. Parent and Merger Sub shall have performed
or complied in all material respects with all agreements and covenants required
by this Agreement to be performed or
                                      -38-

certain Registration Rights Agreement of even date herewith to which Parent and
such holders are parties, Parent shall have obtained consents from certain of
its stockholders who, along with Parent, are parties to an Amended and Restated
Investors' Rights Agreement dated January 28, 1999, and such consent shall be
reasonably satisfactory to the Company.

     6.3  Additional Conditions to the Obligations of Parent and Merger Sub. The

the Closing Date with the same force and effect as if made on and as of the
Closing Date except (A) in each case, or in the aggregate, as does not
constitute a Material Adverse Effect on the Company; provided, however, such
Material Adverse Effect qualification shall be inapplicable with respect to the
representations and warranties contained in Sections 2.2(a) and (b), 2.3, 2.20
and 2.21 and (B) for those representations and warranties which address matters

     7.1  Termination. This Agreement may be terminated at any time prior to the
Effective Time, whether before or after the requisite approvals of the
stockholders of the Company:

        (a) by mutual written consent duly authorized by the Boards of Directors
of Parent and the Company;

        (b) by either the Company or Parent if the Merger shall not have been
consummated by September 30, 1999 (the "END DATE") for any reason; provided,
however, that the right to terminate this Agreement under this Section 7.1(b)
shall not be available to any party whose action or failure to act has
                                      -39-
<PAGE>   482

been a principal cause of or resulted in the failure of the Merger to occur on
or before such date and such action or failure to act constitutes a material
breach of this Agreement;

        (c) by either the Company or Parent if a Governmental Entity shall have
issued an order, decree or ruling or taken any other action, in any case having
the effect of permanently restraining, enjoining or otherwise prohibiting the
Merger, which order, decree, ruling or other action is final and nonappealable;

        (d) by the Company or Parent if the required approval of the
stockholders of the Company contemplated by this Agreement shall not have been
obtained by reason of the failure to obtain the required vote at a meeting of
the Company stockholders duly convened therefor or at any adjournment thereof;
provided, however, that the right to terminate this Agreement under this Section
7.1(d) shall not be available to the Company where the failure to obtain Company
stockholder approval shall have been caused by the action or failure to act of
the Company and such action or failure to act constitutes a material breach by
the Company of this Agreement.

        (e) by Parent (at any time prior to the adoption and approval of this
Agreement and the Merger by the required vote of the stockholders of the
Company) if a Company Triggering Event (as defined below) shall have occurred;

        (f) by the Company, upon a breach of any representation, warranty,
covenant or agreement on the part of Parent set forth in this Agreement, or if
any representation or warranty of Parent shall have become untrue, in either
case such that the conditions set forth in Section 6.2(a) or Section 6.2(b)
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided that if such
inaccuracy in Parent's representations and warranties or breach by Parent is
curable by Parent through the exercise of its commercially reasonable efforts,
then the Company may not terminate this Agreement under this Section 7.1(f)
prior to the End Date, provided Parent continues to exercise commercially
reasonable efforts to cure such breach (it being understood that the Company may
not terminate this Agreement pursuant to this paragraph (f) if it shall have
materially breached this Agreement or if such breach by Parent is cured prior to
the End Date);

        (g) by Parent, upon a breach of any representation, warranty, covenant
or agreement on the part of the Company set forth in this Agreement, or if any
representation or warranty of the Company shall have become untrue, in either
case such that the conditions set forth in Section 6.3(a) or Section 6.3(b)
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided, that if such
inaccuracy in the Company's representations and warranties or breach by the
Company is curable by the Company through the exercise of its commercially
reasonable efforts, then Parent may not terminate this Agreement under this
Section 7.1(g) prior to the End Date, provided the Company continues to exercise
commercially reasonable efforts to cure such breach (it being understood that
Parent may not terminate this Agreement pursuant to this paragraph (g) if it
shall have materially breached this Agreement or if such breach by the Company
is cured prior to the End Date);

        (h) by the Company prior to the Company Stockholders' Meeting in the
event the Meeting Price is less than $38.68 and Parent shall have elected not to
change the Exchange Ratio as provided for in Section 1.6(f)(ii) hereof;

        (i) by Parent prior to the Company Stockholders' Meeting in the event
the Meeting Price exceeds $63.7099 and the Company shall have elected not to
change the Exchange Ratio as provided for in Section 1.6(f)(iii) hereof; and

        (j) by the Company in the event that the Company Board determines (i)
that there is a Superior Offer that has not been withdrawn and (ii) that such
Superior Offer requires a modification in its recommendation to the Company's
stockholders in favor of the Merger and the Board so modifies its recommendation
in compliance with the terms of this Agreement.

        For the purposes of this Agreement, a "COMPANY TRIGGERING EVENT" shall
be deemed to have occurred if: (i) the Company Board or any committee thereof
shall for any reason have withdrawn or shall

                                      -40-
<PAGE>   483

have amended or modified in a manner adverse to Parent its unanimous
recommendation in favor of, the adoption and approval of the Agreement or the
approval of the Merger; (ii) the Company shall have failed to include in the
Prospectus/Proxy Statement the unanimous recommendation of the Company Board in
favor of the adoption and approval of the Agreement and the approval of the
Merger; (iii) the Company Board or any committee thereof shall have approved or
recommended any Acquisition Proposal; (iv) the Company shall have entered into
any letter of intent or similar document or agreement, contract or commitment
accepting any Acquisition Proposal; or (v) a tender or exchange offer relating
to securities of the Company shall have been commenced by a Person unaffiliated

to Rule 14e-2 promulgated under the Securities Act, within ten (10) business
days after such tender or exchange offer is first published sent or given, a
statement disclosing that the Company recommends rejection of such tender or
exchange offer.

     7.2  Notice of Termination; Effect of Termination. Any termination of this
Agreement under Section 7.1 above will be effective immediately upon the
delivery of a valid written notice of the terminating party to the other parties
hereto. In the event of the termination of this Agreement as provided in Section
7.1, this Agreement shall be of no further force or effect, except (i) as set
forth in Section 5.4, this Section 7.2, Section 7.3 and Article 8
(miscellaneous), each of which shall survive the termination of this Agreement,
and (ii) nothing herein shall relieve any party from liability for any willful
breach of this Agreement. No termination of this Agreement shall affect the
obligations of the parties contained in the Confidentiality Agreement, all of
which obligations shall survive termination of this Agreement in accordance with
their terms.

     7.3  Fees and Expenses.

        (a) General. Except as set forth in this Section 7.3, all fees and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether
or not the Merger is consummated; provided, however, that Parent and the Company
shall share equally all fees and expenses, other than attorneys' and accountants
fees and expenses, incurred in relation to the printing and filing (with the
SEC) of the Prospectus/Proxy Statement (including any preliminary materials
related thereto) and the Registration Statement (including financial statements
and exhibits) and any amendments or supplements thereto.

        (b) Company Payments. In the event that this Agreement is terminated by
Parent or the Company, as applicable, pursuant to Sections 7.1(b), (d) (e), or
(j) the Company shall promptly, but in no event later than two days after the
date of such termination, pay Parent a fee equal to $15 million in immediately
available funds (the "TERMINATION FEE"); provided, that in the case of
termination under Section 7.1(b) or 7.1(d), such payment shall be made only if
following the date hereof and prior to the termination of this Agreement, a
third party has publicly announced an Acquisition Proposal and within 12 months
following the termination of this Agreement a Company Acquisition (as defined
below) is consummated or the Company enters into an agreement providing for a
Company Acquisition; provided, further that no termination by the Company giving
rise to the payment of the Termination Fee shall be effective until Parent
actually receives such fee. The Company acknowledges that the agreements
contained in this Section 7.3(b) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, Parent would
not enter into this Agreement; accordingly, if the Company fails to pay in a
timely manner the amounts due pursuant to this Section 7.3(b) , and, in order to
obtain such payment, Parent makes a claim that results in a judgment against the
Company for the amounts set forth in this Section 7.3(b), the Company shall pay
to Parent its reasonable costs and expenses (including attorneys' fees and
expenses) in connection with such suit, together with interest on the amounts
set forth in this Section 7.3(b) at the prime rate of The Chase Manhattan Bank
in effect on the date such payment was required to be made. Payment of the fees
described in this Section 7.3(b) shall not be in lieu of damages incurred in the
event of breach of this Agreement. For the purposes of this Agreement "COMPANY
ACQUISITION" shall mean any of the following transactions (other than the
transactions contemplated by this Agreement); (i) a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company pursuant to which the stockholders of the
Company immediately preceding such transaction hold less than 50% of the
aggregate
                                      -41-
<PAGE>   484

equity interests in the surviving or resulting entity of such transaction, (ii)
a sale or other disposition by the Company of assets representing in excess of
50% of the aggregate fair market value of the Company's business immediately
prior to such sale or (iii) the acquisition by any person or group (including by
way of a tender offer or an exchange offer or issuance by the Company), directly
or indirectly, of beneficial ownership or a right to acquire beneficial
ownership of shares representing in excess of 50% of the voting power of the
then outstanding shares of capital stock of the Company.

     7.4  Amendment. Subject to applicable law, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of Parent and the Company.

     7.5  Extension; Waiver. At any time prior to the Effective Time any party
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

                                  ARTICLE VIII

Board of Directors
Healtheon Corporation
4600 Patrick Henry Road
Santa Clara, CA 95054

Members of the Board:

     We understand that Healtheon Corporation ("Healtheon"), WebMD, Inc.
("WebMD"), and Water Acquisition Corp. ("Merger Sub"), a wholly-owned subsidiary
of Healtheon, entered into an Agreement and Plan of Reorganization, dated May
20, 1999 (the "Reorganization Agreement"), which provides, among other things,
for the merger or other business combination as contemplated by the Agreement
(the "Reorganization") of Merger Sub and WebMD. Pursuant to the Reorganization,
each outstanding share of common stock, no par value, of WebMD (the "WebMD
Common Stock"), other than shares held in treasury or held by Healtheon or any
subsidiary of WebMD or Healtheon or as to which dissenters' rights have been
perfected, will be converted into the right to receive 1.815 shares (the
"Exchange Ratio") of common stock, par value $0.0001 per share of Healtheon (the
"Healtheon Common Stock"). The terms and conditions of the Reorganization are
more fully set forth in the Reorganization Agreement.

     We also understand that, in connection with the execution and delivery of
the Reorganization Agreement:

       (i) WebMD will enter into voting and conversion agreements with certain
           stockholders of WebMD;

      (ii) WebMD will enter into a stockholder agreement with Microsoft
           Corporation ("Microsoft"); and

      (iii) Healtheon will enter into voting agreements with certain
            stockholders of Healtheon.

     We further understand, that among the conditions to the Reorganization,
WebMD will have received investments (the foregoing, collectively, the
"Strategic Investments"):

     (i)   from Microsoft pursuant to the terms of the investment agreement
           dated May 12, 1999 among WebMD, Microsoft and certain other parties
           named therein (the "Investment Agreement") in an amount equal to
           $150,000,000 in exchange for 276,906 shares of Series E Preferred
           Stock of WebMD (the "Series E Preferred Stock");

     (ii)  from investors other than Microsoft pursuant to the Investment
           Agreement in an amount equal to $114,500,000 in exchange for 211,372
           shares of Series E Preferred Stock; and

     (iii)  from investors other than Microsoft pursuant to one or more
            agreements in substantially the same form as the Investment
            Agreement in an amount equal to $35,000,000 in exchange for 65,534
            shares of Series E Preferred Stock;

     We also note that Microsoft has commenced a tender offer (the "Microsoft
Tender Offer") for all outstanding shares of Series F Preferred Stock of WebMD
pursuant to an Offer to Purchase dated April 10, 1999 (the "Offer to Purchase")
and that the consummation of such Microsoft Tender Offer is not a condition to
the consummation of the Reorganization.

     You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Agreement is fair from a financial point of view to Healtheon.

           information of Healtheon, including the pro forma impact of
           Healtheon's proposed acquisition of Mede America Corporation ("Pro

            and trading prospects of each of Pro Forma Healtheon and WebMD,
            including information relating to certain strategic, financial and
            operational benefits anticipated from each Strategic Investment,
            with senior executives of Healtheon and WebMD, respectively;

     (viii) discussed the effect of the Strategic Investments on the business
            and trading prospects of Pro Forma Healtheon and WebMD pro forma for
            the Reorganization, including information relating to certain
            strategic, financial and operational benefits anticipated from each
            Strategic Investment, with senior executives of Healtheon and WebMD;

     (ix)  reviewed the pro forma impact of the Reorganization on the income
           statement of Pro Forma Healtheon;

     (x)  reviewed the reported prices and trading activity of the Healtheon

     (xi)  compared the financial performance of Pro Forma Healtheon and WebMD
           and the prices and trading activity of the Healtheon Common Stock
           with that of certain publicly-traded companies comparable to
           Healtheon and WebMD and their securities;

     (xii)  participated in negotiations and discussions among representatives
            of Healtheon, WebMD and Microsoft and other investors to the
            Strategic Investments and their respective advisors;

     (xiii) reviewed the Reorganization Agreement, as well as certain other

            amended on February 26, 1999, as well as certain documents related
            to the foregoing; and

     (xv)  performed such other analysis and considered such other factors as we
           have deemed appropriate.

     We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the internal financial statements and other
financial and operating data, including forecasts, and discussions relating to
the strategic, financial and operational benefits anticipated from the Strategic
Investments and from the Reorganization provided by Healtheon and WebMD, we have
assumed that they have, in each case, been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the prospects
of Pro Forma Healtheon and WebMD. We have relied upon the assessment by the
managements of Healtheon and WebMD of their ability to retain key employees of
Pro Forma Healtheon and WebMD. We have also relied upon, without independent
verification, the assessment by the managements of Healtheon and WebMD of (i)
the strategic and other benefits expected to result from the Reorganization;
(ii) the timing and risks associated with the integration of Pro Forma Healtheon
and WebMD; and (iii) the validity of, and risks associated with, Pro Forma
Healtheon's and WebMD's existing and future products and technologies. We have
not made any independent valuation or appraisal of the assets or liabilities or
technology of Pro Forma Healtheon and WebMD, nor have we been furnished with any
such appraisals. In addition, we have assumed that the Reorganization will be
treated as a tax-free reorganization and/or exchange, pursuant to the Internal
Revenue Code of 1986 and will be consummated in accordance with the terms set
forth in the Reorganization Agreement. We have also assumed that all Strategic
Investments will be consummated in accordance with the terms of the Investment
Agreement, and that the Microsoft Tender Offer will not materially delay, or
otherwise have a material adverse effect on the consummation of the
Reorganization. Our opinion is necessarily based on financial, economic, market
and other conditions as in effect on, and the information made available to us
as of, the date hereof.

     We have acted as financial advisor to the Board of Directors of Healtheon
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financing and advisory services for Healtheon, Microsoft and certain other
parties to the Strategic Investments and have received fees for the rendering of
these services. Morgan Stanley is also an equity owner of Healtheon as a result
in Morgan Stanley's participation in a private placement. In the ordinary course
of our business we may actively trade the securities of Healtheon, Microsoft or
any of the other parties to the Strategic Investments, for our own account and
for the accounts of our customers and, accordingly, may at any time hold a long
or short position in such securities.

     It is understood that this letter is for the information of the Board of
Directors of Healtheon and may not be used for any other purpose without our
prior written consent. In addition, this opinion does not in any manner address
the prices at which the Healtheon Common Stock will actually trade following
consummation of the Reorganization, and Morgan Stanley expresses no opinion or
recommendation as to how the stockholders of Healtheon Common Stock and WebMD
Common Stock should vote at the shareholders' meetings held in connection with
the Reorganization.

     Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Reorganization Agreement is fair
from a financial point of view to Healtheon.

                                          Very truly yours,

                                          MORGAN STANLEY & CO. INCORPORATED

                                  May 20, 1999

Board of Directors
WebMD, Inc.
400 The Lenox Building
3399 Peachtree Road NE
Atlanta, GA 30326

Members of the Board:

     We understand that WebMD, Inc. ("WebMD"), Healtheon Corporation
("Healtheon"), Water Acquisition Corp. (a wholly owned subsidiary of Healtheon,
"Merger Sub") and WebMD principal stockholders are proposing to enter into an
Agreement and Plan of Reorganization (the "Agreement") which will provide, among
other things, for the merger (the "Merger") of Merger Sub with and into WebMD.
Upon consummation of the Merger, WebMD will become a wholly owned subsidiary of
Healtheon. Under the terms set forth in the Agreement, at the effective time of
the Merger, each outstanding share of common stock of WebMD, no par value
("WebMD Common Stock"), other than certain shares to be canceled pursuant to the
Agreement and shares held by stockholders who properly exercise dissenters'
rights ("Dissenting Shares"), will be converted into the right to receive 1.815
shares (the "Exchange Ratio") of the common stock of Healtheon, par value
$0.0001 per share ("Healtheon Common Stock"). The terms and conditions of the
Merger are set out more fully in the Agreement.

     You have asked us whether, in our opinion, the Exchange Ratio is fair from
a financial point of view and as of the date hereof to the "Holders of WebMD
Common Stock". The "Holders of WebMD Common Stock" shall be defined to include
all holders of WebMD Common Stock other than Healtheon, Merger Sub, any
affiliates of Healtheon or Merger Sub or holders of Dissenting Shares.

     For purposes of this opinion we have, among other things:

     (i) reviewed certain publicly available financial statements and other
         business and financial information of Healtheon;

     (ii) reviewed certain internal financial statements and other financial and
          operating data concerning WebMD and Healtheon, including information
          relating to certain strategic, financial and operational benefits
          anticipated from the Merger, prepared by the managements of WebMD and
          Healtheon, respectively;

     (iii) reviewed certain financial forecasts and other forward looking
           financial information prepared by the managements of WebMDand
           Healtheon, respectively;

     (iv) held discussions with the respective managements of WebMD and
          Healtheon concerning the businesses, past and current operations,
          financial condition and future prospects of both WebMD and Healtheon,
          independently and combined, including discussions with the managements
          of WebMD and Healtheon concerning cost savings and other synergies
          that are expected to result from the Merger as well as their views
          regarding the strategic rationale for the Merger;

     (v) reviewed the financial terms and conditions set forth in the Agreement;

     (vi) reviewed the stock price and trading history of Healtheon;

     (vii) compared the financial performance of WebMD and Healtheon and the
           prices and trading activity of Healtheon Common Stock with that of
           certain other publicly traded companies comparable with WebMD and
           Healtheon, respectively;

     (viii) compared the financial terms of the Merger with the financial terms,
            to the extent publicly available, of other transactions that we
            deemed relevant;
<PAGE>   492
Board of Directors
WebMD, Inc.
May 20, 1999
Page  2

     (ix) reviewed the pro forma impact of the Merger on Healtheon's revenues
          and cash earnings per share;

     (x) reviewed and considered in the analysis, information prepared by
         members of management of WebMD and Healtheon relating to the relative
         contributions of WebMD and Healtheon to the combined company;

     (xi) prepared an analysis of WebMD with respect to an initial public
          offering;

     (xii) participated in discussions and negotiations among representatives of
           WebMD and Healtheon and their financial and legal advisors; and

     (xiii) made such other studies and inquiries, and reviewed such other data,
            as we deemed relevant.

     In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided to us (including information furnished to us orally or
otherwise discussed with us by management of WebMD and Healtheon) or publicly
available and have neither attempted to verify, nor assumed responsibility for
verifying, any of such information. We have relied upon the assurances of
management of WebMD and Healtheon that they are not aware of any facts that
would make such information inaccurate or misleading. Furthermore, we did not
obtain or make, or assume any responsibility for obtaining or making, any
independent evaluation or appraisal of the properties, assets or liabilities
(contingent or otherwise) of WebMD or Healtheon, nor were we furnished with any
such evaluation or appraisal. With respect to the financial forecasts and
projections (and the assumptions and bases therefor) for each of WebMD and
Healtheon that we have reviewed, upon the advice of the managements of WebMD and
Healtheon, we have assumed that such forecasts and projections have been
reasonably prepared in good faith on the basis of reasonable assumptions and
reflect the best currently available estimates and judgments as to the future
financial condition and performance of WebMD and Healtheon, respectively, and we
have further assumed that such projections and forecasts will be realized in the
amounts and in the time periods currently estimated. In this regard, we note
that each of WebMD and Healtheon face exposure to the Year 2000 problem. We have
not undertaken any independent analysis to evaluate the reliability or accuracy
of the assumptions made by the managements of WebMD and Healtheon with respect
to the potential effect that the Year 2000 problem might have on their
respective forecasts. We have assumed that the Merger will be consummated upon
the terms set forth in the Agreement without material alteration thereof,
including, among other things, that the Merger will be accounted for as a
"purchase method" business combination in accordance with U.S. generally
accepted accounting principles ("GAAP") and that the Merger will be treated as a
tax-free reorganization pursuant to the Internal Revenue Code of 1986, as
amended. In addition, we have assumed that the historical financial statements
of each of WebMD and Healtheon reviewed by us have been prepared and fairly
presented in accordance with U.S. GAAP consistently applied. We have also
assumed that the Exchange Ratio will not be reduced as a result of
indemnification or other provisions of the Agreement. We have relied as to all
legal matters relevant to rendering our opinion on the advice of counsel.

     This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect the
conclusion expressed in this opinion and that we disclaim any undertaking or
obligation to advise any person of any change in any matter affecting this
opinion which may come or be brought to our attention after the date of this
opinion. Our opinion is limited to the fairness, from a financial point of view
and as to the date hereof, to the Holders of WebMD Common Stock of the Exchange
Ratio. We do not express any opinion as to (i) the value of any employee
agreement or other arrangement entered into in connection with the Merger, (ii)
any tax or other consequences that might

WebMD, Inc.

Page  3

result from the Merger or (iii) what the value of Healtheon Common Stock will be
when issued to WebMD's stockholders pursuant to the Merger or the price at which
the shares of Healtheon Common Stock that are issued pursuant to the Merger may
be traded in the future. Our opinion does not address the relative merits of the
Merger and the other business strategies that WebMD's Board of Directors has
considered or may be considering, nor does it address the decision of WebMD's
Board of Directors to proceed with the Merger.

     In connection with the preparation of our opinion, we were not authorized
to solicit, and did not solicit, third-parties regarding alternatives to the
Merger.

     We are acting as financial advisor to WebMD in connection with the Merger
and will receive (i) a fee contingent upon the delivery of this opinion and (ii)
an additional fee contingent upon the consummation of the Merger. In addition,
WebMD has agreed to indemnify us for certain liabilities that may arise out of
the rendering of this opinion. In the past, we have provided certain investment
banking services to WebMD for which we will be paid fees, including acting as
WebMD's exclusive financial advisor in connection with the tender offer
currently outstanding from Medicine Company ("Medicine") and the pending private
investments by, among others, Medicine. In the ordinary course of business, we
may trade in Healtheon's securities for our own account and the account of our
customers and, accordingly, may at any time hold a long or short position in
Healtheon's securities.

     Our opinion expressed herein is provided for the information of the Board
of Directors of WebMD in connection with its evaluation of the Merger. Our
opinion is not intended to be and does not constitute a recommendation to any
stockholder of WebMD or Healtheon as to how such stockholder should vote, or
take any other action, with respect to the Merger. This opinion may not be
summarized, described or referred to or furnished to any party except with our
express prior written consent.

     Based upon and subject to the foregoing considerations, it is our opinion
that, as of the date hereof, the Exchange Ratio is fair to the Holders of WebMD
Common Stock from a financial point of view.

                                          Very truly yours,

April 20, 1999

The Board of Directors
MedE America Corporation
90 Merrick Avenue
East Meadow, New York 11554

Members of the Board:

     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of the common stock of MedE America Corporation ("MedE
America") of the Exchange Ratio (defined below) provided for in the Agreement
and Plan of Reorganization, dated as of April 20, 1999 (the "Agreement"), among
Healtheon Corporation ("Healtheon"), Merc Acquisition Corp., a wholly owned
subsidiary of Healtheon ("Merger Sub"), and MedE America. As more fully
described in the Agreement, (i) Merger Sub will be merged with and into MedE
America (the "Merger") and (ii) each outstanding share of the common stock, par
value $0.01 per share, of MedE America (the "MedE America Common Stock") will be
converted into the right to receive 0.6593 (the "Exchange Ratio") of a share of
the common stock, par value $0.0001 per share, of Healtheon (the "Healtheon
Common Stock"), subject to adjustment, as specified in the Agreement, in the
event that the 10 day average closing price for Healtheon Common Stock for the
period ending two days prior to MedE America's stockholders' meeting in respect
of the Merger is less than $38.68 or more than $63.70.

     In arriving at our opinion, we reviewed the Agreement and held discussions
with certain senior officers, directors and other representatives and advisors
of MedE America and certain senior officers and other representatives and
advisors of Healtheon concerning the businesses, operations and prospects of
MedE America and Healtheon. We examined certain publicly available business and
financial information relating to MedE America and Healtheon as well as certain
financial forecasts and other information and data for MedE America and
Healtheon which were provided to or otherwise discussed with us by the
respective managements of MedE America and Healtheon, including information
relating to certain strategic implications and operational benefits anticipated
to result from the Merger. We reviewed the financial terms of the Merger as set
forth in the Agreement in relation to, among other things: current and
historical market prices and trading volumes of the MedE America Common Stock
and Healtheon Common Stock; the historical and projected earnings and other
operating data of MedE America and Healtheon; and the capitalization and
financial condition of MedE America and Healtheon. We considered, to the extent
publicly available, the financial terms of other transactions recently effected
which we considered relevant in evaluating the Merger and analyzed certain
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations we considered relevant in
evaluating those of MedE America and Healtheon. We also evaluated the potential
pro forma financial impact of the Merger on Healtheon. In addition to the
foregoing, we conducted such other analyses and examinations and considered such
other financial, economic and market criteria as we deemed appropriate in
arriving at our opinion.

     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the managements of MedE America and Healtheon that such forecasts and
other information and data were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the managements of MedE America
and Healtheon as to the future financial performance of MedE America and
Healtheon and the strategic implications and operational benefits anticipated to
result from the Merger. We have assumed, with your consent, that the Merger will
be treated as a tax-free reorganization for federal income tax purposes. Our
opinion, as set forth herein, relates to the relative values of MedE
<PAGE>   495

America and Healtheon. We are not expressing any opinion as to what the value of
the Healtheon Common Stock actually will be when issued to MedE America
stockholders pursuant to the Merger or the price at which the Healtheon Common
Stock will trade subsequent to the Merger. We have not made or been provided
with an independent evaluation or appraisal of the assets or liabilities
(contingent or otherwise) of MedE America or Healtheon nor have we made any
physical inspection of the properties or assets of MedE America or Healtheon. In
connection with our opinion, we were not requested to, and we did not, solicit
third party indications of interest in the possible acquisition of all or a part
of MedE America; however, we did, at the request of MedE America, solicit third
party indications of interest in the possible acquisition of MedE America prior
to MedE America's initial public offering in February 1999. We express no view
as to, and our opinion does not address, the relative merits of the Merger as
compared to any alternative business strategies that might exist for MedE
America or the effect of any other transaction in which MedE America might
engage. Our opinion is necessarily based upon information available to us, and
financial, stock market and other conditions and circumstances existing and
disclosed to us, as of the date hereof.

     Salomon Smith Barney Inc. has acted as financial advisor to MedE America in
connection with the proposed Merger and will receive a fee for such services, a
significant portion of which is contingent upon the consummation of the Merger.
We also will receive a fee upon the delivery of this opinion. We have in the
past provided certain investment banking services to MedE America unrelated to
the proposed Merger, for which services we have received compensation. In the
ordinary course of our business, we and our affiliates may actively trade or
hold the securities of MedE America and Healtheon for our own account or for the
account of our customers and, accordingly, may at any time hold a long or short
position in such securities. In addition, we and our affiliates (including
Citigroup Inc. and its affiliates) may maintain relationships with MedE America,
Healtheon and their respective affiliates.

     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of MedE America in its evaluation of the
proposed Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed Merger.

     Based upon and subject to the foregoing, our experience as investment

following corporate actions:

           (1) Consummation of a plan of merger to which the corporation is a
party:

substantially all of the net proceeds of the sale will be distributed to the
shareholders within one year after the date of sale;

           (4) An amendment of the articles of incorporation that materially and

               (A) Alters or abolishes a preferential right of the shares;

               (B) Creates, alters, or abolishes a right in respect of

issuance of shares or other securities with similar voting rights;

               (E) Reduces the number of shares owned by the shareholder to a
fraction of a share if the fractional share so created is to be acquired for
cash under Code Section 14-2-604; or

               (F) Cancels, redeems, or repurchases all or part of the shares of
the class; or

           (5) Any corporate action taken pursuant to a shareholder vote to the
extent that Article 9 of this chapter, the articles of incorporation, bylaws, or
a resolution of the board of directors provides that voting or nonvoting
shareholders are entitled to dissent and obtain payment for their shares.

        (b) A shareholder entitled to dissent and obtain payment for his shares
under this article may not challenge the corporate action creating his
entitlement unless the corporate action fails to comply with procedural
requirements of this chapter or the articles of incorporation or bylaws of the
corporation or the vote required to obtain approval of the corporate action was
obtained by fraudulent and deceptive means, regardless of whether the
shareholder has exercised dissenter's rights.

        (c) Notwithstanding any other provision of this article, there shall be
no right of dissent in favor of the holder of shares of any class or series
which, at the record date fixed to determine the shareholders entitled to
receive notice of and to vote at a meeting at which a plan of merger or share
exchange or a sale or exchange of property or an amendment of the articles of
incorporation is to be acted on, were either listed on a national securities
exchange or held of record by more than 2,000 shareholders, unless:

           (1) In the case of a plan of merger or share exchange, the holders of
shares of the class or series are required under the plan of merger or share
exchange to accept for their shares anything except shares of the surviving
corporation or another publicly held corporation which at the effective date of
the merger or share exchange are either listed on a national securities exchange
or held of record by more than 2,000 shareholders, except for scrip or cash
payments in lieu of fractional shares; or

           (2) The articles of incorporation or a resolution of the board of
directors approving the transaction provides otherwise. (Code 1981, Sec.
14-2-1302, enacted by Ga. L. 1988, p. 1070, Sec. 1; Ga. L.1989, p. 946, Sec.
58.)

14-2-1303. Dissent by nominees and beneficial owners.

     A record shareholder may assert dissenters' rights as to fewer than all the
shares registered in his name only if he dissents with respect to all shares
beneficially owned by any one beneficial shareholder and notifies the
corporation in writing of the name and address of each person on whose behalf he
asserts dissenters' rights.
<PAGE>   498

     The rights of a partial dissenter under this Code section are determined as
if the shares as to which he dissents and his other shares were registered in
the names of different shareholders.

(Code 1981, Sec. 14-2-1303, enacted by Ga. L. 1988, p. 1070, Sec. 1.)

rights under this article and be accompanied by a copy of this article.

     (b) If corporate action creating dissenters' rights under Code Section
14-2-1302 is taken without a vote of shareholders, the corporation shall notify
in writing all shareholders entitled to assert dissenters' rights that the
action was taken and send them the dissenters' notice described in Code Section
14-2-1322 no later than ten days after the corporate action was taken.

(Code 1981, Sec. 14-2-1320, enacted by Ga. L. 1988, p. 1070, Sec. 1; Ga. L.1993,
p. 1231, Sec. 17.)

14-2-1321. Notice of intent to demand payment.

        (a) If proposed corporate action creating dissenters' rights under Code
Section 14-2-1302 is submitted to a vote at a shareholders' meeting, a record
shareholder who wishes to assert dissenters' rights:

           (1) Must deliver to the corporation before the vote is taken written
notice of his intent to demand payment for his shares if the proposed action is
effectuated; and

           (2) Must not vote his shares in favor of the proposed action.

        (b) A record shareholder who does not satisfy the requirements of
subsection (a) of this Code section is not entitled to payment for his shares

the shares will be restricted after the payment demand is received;

        (3) Set a date by which the corporation must receive the payment demand,

        (4) Be accompanied by a copy of this article.

(Code 1981, Sec. 14-2-1322, enacted by Ga. L. 1988, p. 1070, Sec. 1.)

uncertificated shares retains all other rights of a shareholder until these

(Code 1981, Sec. 14-2-1324, enacted by Ga. L. 1988, p. 1070, Sec. 1.)

(Code 1981, Sec. 14-2-1325, enacted by Ga. L. 1988, p. 1070, Sec. 1; Ga. L.

14-2-1327. Procedure if shareholder dissatisfied with payment or offer.

     (a) A dissenter may notify the corporation in writing of his own estimate
of the fair value of his shares and amount of interest due, and demand payment
of his estimate of the fair value of his shares and interest due, if:

        (1) The dissenter believes that the amount offered under Code Section
14-2-1325 is less than the fair value of his shares or that the interest due is
incorrectly calculated; or

        (2) The corporation, having failed to take the proposed action, does not
return the deposited certificates or release the transfer restrictions imposed
on uncertificated shares within 60 days after the date set for demanding
payment.

     (b) A dissenter waives his or her right to demand payment under this Code
section and is deemed to have accepted the corporation's offer unless he or she

this Code section within 30 days after the corporation offered payment for his
or her shares, as provided in Code Section 14-2-1325.

     (c) If the corporation does not offer payment within the time set forth in

(Code 1981, Sec. 14-2-1327, enacted by Ga. L. 1988, p. 1070, Sec. 1; Ga. L.
1989, p. 946, Sec. 60; Ga. L. 1990, p. 257, Sec. 21; Ga. L. 1993, p. 1231, Sec.
19.)

14-2-1330 Court action.

     (a) If a demand for payment under Code Section 14-2-1327 remains unsettled,
the corporation shall commence a proceeding within 60 days after receiving the
payment demand and petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the proceeding within
the 60 day period, it shall pay each dissenter whose demand remains unsettled
the amount demanded.

     (b) The corporation shall commence the proceeding, which shall be a nonjury
equitable valuation proceeding, in the superior court of the county where a
corporation's registered office is located. If the surviving corporation is a
foreign corporation without a registered office in this state, it shall commence
the proceeding in the county in this state where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
corporation was located.

     (c) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding, which
shall have the effect of an action quasi in rem against their shares. The
corporation shall serve a copy of the petition in the proceeding upon each
dissenting shareholder who is a resident of this state in the manner provided
bylaw for the service of a summons and complaint, and upon each nonresident
dissenting shareholder either by registered or certified mail or by publication,
or in any other manner permitted by law.

     (d) The jurisdiction of the court in which the proceeding is commenced
under subsection (b) of this Code section is plenary and exclusive. The court
may appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value. The appraisers have the powers described
in the order appointing them or in any amendment to it. Except as otherwise
provided in this chapter,
<PAGE>   501

Chapter 11 of Title 9, known as the "Georgia Civil Practice Act," applies to any
proceeding with respect to dissenters' rights under this chapter.

     (e) Each dissenter made a party to the proceeding is entitled to judgment
for the amount which the court finds to be the fair value of his shares, plus
interest to the date of judgment.

(Code 1981, Sec. 14-2-1330, enacted by Ga. L. 1988, p. 1070, Sec. 1; Ga. L.1989,
p. 946, Sec. 61; Ga. L. 1993, p. 1231, Sec. 20.)

14-2-1331 Court costs and counsel fees.

     (a) The court in an appraisal proceeding commenced under Code Section
14-2-1330 shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court, but not
including fees and expenses of attorneys and experts for the respective parties.
The court shall assess the costs against the corporation, except that the court
may assess the costs against all or some of the dissenters, in amounts the court
finds equitable, to the extent the court finds the dissenters acted arbitrarily,
vexatiously, or not in good faith in demanding payment under Code Section
14-2-1327.

     (b) The court may also assess the fees and expenses of attorneys and
experts for the respective parties, in amounts the court finds equitable:

        (1) Against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the requirements
of Code Sections 14-2-1320 through 14-2-1327; or

     (2) Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses are
assessed acted arbitrarily, vexatiously, or not in good faith with respect to
the rights provided by this article.

     (c) If the court finds that the services of attorneys for any dissenter
were of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these attorneys reasonable fees to be paid out of the amounts
awarded the dissenters who were benefited.

(Code 1981, Sec. 14-2-1331, enacted by Ga. L. 1988, p. 1070, Sec. 1.)

14-2-1332 Limitation of actions.

     No action by any dissenter to enforce dissenters' rights shall be brought
more than three years after the corporate action was taken, regardless of
whether notice of the corporate action and of the right to dissent was given by
the corporation in compliance with the provisions of

Code Section 14-2-1320 and Code Section 14-2-1322. (Code 1981, Sec. 14-2-1332,
enacted by Ga. L. 1988, p. 1070, Sec. 1.)

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. The
Registrant's Bylaws provide for the mandatory indemnification of its directors,
officers, employees and other agents to the maximum extent permitted by Delaware
General Corporation Law, and the Company has entered into agreements with its
officers, directors and certain key employees implementing such indemnification.

++ Incorporated by reference to Healtheon's Amendment No. 1 to its Registration
   Statement on Form S-1 filed February 4, 1999.

(b) FINANCIAL STATEMENT SCHEDULES

     Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements, management's discussion and analysis or notes thereto.

ITEM 22. UNDERTAKINGS

     (1) The undersigned Registrant hereby undertakes as follows: that prior to
any public offering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
undersigned Registrant undertakes that such offering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other Items of the applicable form.

     (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (3) Insofar as the indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to Directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and

                                      II-3
<PAGE>   505

Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     (4) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.

     (5) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

RE:  REGISTRATION STATEMENT ON FORM S-4


Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-4 to be filed by you
with the Securities and Exchange Commission on or about June 17, 1999 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 190,597,448 shares of your Series A
Common Stock (the "Shares"). As your legal counsel in connection with this
transaction, we have examined the proceedings taken and are familiar with the
proceedings proposed to be taken by you in connection with the issuance of the
Shares pursuant to the acquisition transaction set forth and described in the
Registration Statement.

     It is our opinion that, when issued in the manner described in the
Registration Statement, the Shares will be legally and validly issued,
fully-paid and non-assessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name whenever appearing in the
Registration Statement and any amendments thereto.


                                              Very truly yours,


                                              --------------------------------
