Offering"). If the Company does not close the Initial Public Offering at an
offering price of $18.00 per share (as adjusted for any stock splits, stock
dividends, combinations or the like) on or before the date that is one hundred

Company closes the Initial Public Offering within such 180-day period, but does
so at an offering price less than $18.00 per share (as adjusted for any stock
splits, stock dividends, combinations or the like), such shares shall consist of
Common Stock rather than Preferred Stock. Furthermore, in the event the Company
fails to close the Initial Public Offering on or before the first anniversary of
the Closing Date, the Company shall issue promptly to Purchaser, for no
additional consideration, an additional 50,000 shares of Preferred Stock without
need for any further action by Purchaser. The numbers of shares of stock

any such contract, agreement or instrument has breached any provision of, or is
in default under, the terms thereof, and there are no claims or allegations of
offset, defense, or counterclaims that would prevent the work in process of any
of the Company and the Subsidiaries or its contracts and agreements from
maturing in due course into fully collectible accounts receivable. Except as set
forth on Exhibit 3.11, each of the Company and the Subsidiaries has complied
         ------------
with all applicable statutes, ordinances, rules, regulations and orders relating
to seeking, bidding, obtaining, performing under or otherwise complying with,
contracts with governmental and quasi-governmental authorities, agencies or
other entities.

     3.12 Computer Software.
          ----------------- 

          3.12.1  Exhibit 3.12.1 contains a complete and accurate list of the
                  --------------                                             
computer software that is owned by each of the Company and the Subsidiaries and
used in their respective businesses (the "Owned Software"), except for
commercially available business software applications and other commercially
available over-the-counter "shrink-wrap" software that is generally used by any
of the Company and the Subsidiaries in the ordinary course of its business (the
"Business Software").  To the Company's Knowledge, except for the Licensed
Software (as such term is defined below) incorporated within the Owned Software,
and except as otherwise set forth in Exhibit 3.12.1, each of the Company and the
                                     --------------                             
Subsidiaries has exclusive rights and title to the Owned Software, free and
clear of all claims, including claims or rights of joint owners and employees,
agents, consultants, customers, licensees or any other parties who may have been
involved in the development, creation, marketing, maintenance, enhancement or
licensing of such Owned Software.  Each contract programmer, independent
contractor, nonemployee agent and person or other entity (other than employees)
who has performed development or computer programming services for any of the
Company and the Subsidiaries in connection with the Owned Software has executed
a confidentiality agreement in favor of the Company or any Subsidiary, and each
of the Company and the Subsidiaries has obtained an assignment or license of, or
otherwise owns, the intellectual property resulting therefrom.  No Owned
Software has been published or disclosed to any other parties except pursuant to
contracts requiring such other parties to keep the Owned Software confidential.
(For purposes of the preceding sentence, marketing materials that describe the
Owned Software and its functions in general shall not be deemed a publication or
disclosure of the Owned Software.)  To the best of the Company's Knowledge, no
such other party has breached any such obligation of confidentiality.

          3.12.2   Each of the Company and the Subsidiaries has the right and
license to use, sublicense, modify and copy all software (other than the
Business Software) of which each of the Company and the Subsidiaries is a
licensee or lessee or that each of the Company and the Subsidiaries otherwise
has obtained the right to use (collectively, the "Licensed Software") to the
extent necessary to operate each of the Company's and any Subsidiary's business,
free and clear of any limitations or encumbrances, including Licensed Software
that 

                                       6


 
has been incorporated into or made a part of any Owned Software. Each of the
Company and the Subsidiaries is in full compliance with all material provisions
of each license, lease or other agreement relating to the Licensed Software.
Neither the Company nor any Subsidiary has published or disclosed any Licensed
Software to any other party except, in the case of Licensed Software, if any,
that any of the Company and the Subsidiaries leases or markets to others,
pursuant to contracts requiring such other parties to keep the Licensed Software
confidential. To the best of the Company's Knowledge, no party to whom any of
the Company and the Subsidiaries has disclosed Licensed Software has breached
such obligation of confidentiality.

          3.12.3  The Owned Software, the Licensed Software, and the Business
Software constitute all software used in any of the Company's and any
Subsidiary's business (the "Company Software"). The transactions contemplated
herein will not cause a breach or default under any licenses, leases or similar
agreements relating to the Company Software or impair any of the Company's and
any Subsidiary's ability to use the Company Software in the same manner as the
Company Software is currently used or is contemplated to be used by the Company.
Neither the Company nor any Subsidiary has infringed or is infringing any
intellectual property rights of any third party with respect to the Owned
Software, and, to the best of the Company's Knowledge, no other person or entity
is infringing any intellectual property rights of any of the Company and the
Subsidiaries with respect to the Owned Software.

          3.12.4  Except as disclosed in Exhibit 3.12.4, neither the Company nor
                                         --------------                         
any Subsidiary has granted any licenses or other rights, and neither the Company
nor any Subsidiary has any obligation to grant licenses or other rights, with
respect to the Company Software.  Each of the Company and the Subsidiaries has
complied in all material respects with the obligations to its customers,
licensees and lessees in respect of the Company Software, if any, listed in
Exhibit 3.12.4.
-------------- 

          3.12.5  Neither the Company nor any Subsidiary has granted marketing
or brokering rights in the Company Software to any third party.

          3.12.6  The Business Software that is material to the operation of the
Company's or any Subsidiary's business, the Owned Software and any Licensed
Software that has been incorporated into any Owned Software is capable of
correctly processing, providing and/or receiving date data within and between
the Twentieth and Twenty-First Centuries, provided that all hardware, software
and firmware used with the Company Software and computer equipment properly
exchanges accurate date data with it.  To the Company's Knowledge after
reasonable inquiry, the business of neither the Company nor any Subsidiary
depends to any extent on embedded computer technology or computer information
systems of its current vendors or suppliers that would, in the event that the
embedded chips or vendor/supplier computer systems fail to be Year 2000
compliant, have a material adverse effect on the Company's or any Subsidiary's
business or properties.

     3.13 Protection of Intellectual Property Generally.  Exhibit 3.13 hereto
          ---------------------------------------------   ------------       
sets forth a complete and correct list and summary description of all registered
and material unregistered 

                                       7


 
trademarks, trade or company names, service marks, service names, brand names
and registrations, if any, therefor; all registered copyrights; all patents and
all patent applications, if any, in each case applicable to or used or intended
to be used in the business of any of the Company and the Subsidiaries, together
with a complete list of all licenses granted by or to each of the Company and
the Subsidiaries with respect to any of the above. The Company has filed an
application in the United States Patent and Trademark Office for registration of
WebMD as a service mark (which application has been initially denied), but
otherwise neither the Company nor any Subsidiary has not sought governmental
protection by way of patent, trademark or copyright registration or application
for the property listed in Exhibit 3.13 hereto. Each of the Company and the
                           ------------

          ---------------

8.   RIGHT OF FIRST REFUSAL -- ANSWERING SERVICE BUSINESS.

     8.1  Grant of Right.  During the period commencing on the Closing Date and
          --------------                                                       
ending on the third (3rd) anniversary of the Closing Date, in the event that the
Company proposes to sell all or substantially all the Company's physician-only
answering service business (hereinafter referred to as the "Answering Service
Business") to a third party other than an Affiliate (as such term is defined
below) of the Company (the "Offeror"), whether such sale involves the assets of
the Answering Service Business or the stock of an Affiliate of the Company that
owns the assets associated with the Answering Service Business, Purchaser shall
have the right to purchase all, but not less than all, such assets or stock (the
"Answering Service Right of First Refusal"); provided, however, that such
Answering Service Right of First Refusal shall be subject to the exclusive
option of Matria Healthcare, Inc. to provide after-hours call support services
as a subcontractor to the Company in respect of the Answering Service Business
in the specialty areas of obstetrics and gynecology and cardiology; provided,
further, that such Answering Service Right of First Refusal shall not apply to a
proposal to sell substantially all of the assets of the Company or the stock of
such subsidiary, unless the business of the Company or such subsidiary consists
exclusively or nearly exclusively of the Answering Service Business. For
purposes of this Section 8.1, the term "Affiliate" shall mean any corporation,
partnership, limited liability company, or other entity that controls, is
controlled by, or is under common control with the Company, with "control" being
defined for this purpose as ownership of a majority of the voting interest of
the entity so controlled.

     8.2  Notice of Proposed Transfer.  Before effecting any proposed transfer
          ---------------------------                                         
of all or substantially all of the Answering Service Business, the Company shall
give written notice to Purchaser describing fully the proposed transfer,
including the particular assets to be transferred, the name and address of the
proposed transferee(s) and the proposed transfer price, and the fair market
value of any proposed non-cash consideration (as provided in Section 8.4 below)
(the "Transfer Notice").  The Transfer Notice shall contain an accurate summary
of the offer of the Offeror, which must be a binding and bona fide offer.

     8.3  Exercise of Right.  At any time within the ten (10)-business day
          -----------------                                               
period immediately following receipt of the Transfer Notice, Purchaser may elect
to purchase all, but not less than all, of the assets subject to the Transfer
Notice at the price and upon the terms set forth therein by written notice to
the Company (the "Election Notice"); provided, however, that the Company and
Purchaser shall enter into a definitive agreement within the thirty (30)-day
period immediately following receipt of the Transfer Notice.

     8.4  Closing of Purchase.  The closing of any sale and purchase of the
          -------------------                                              
assets subject to the Transfer Notice shall be held at the offices of the
Company, on a date and time 

                                       18


 
agreed upon by the Company and Purchaser, provided that such closing shall in no
event be held more than forty-five (45) days after delivery of the Election
Notice or within ten (10) business days following the receipt of all required
governmental approvals, whichever is later. If Purchaser fails to exercise the
Answering Service Right of First Refusal in a timely manner as to all the assets
subject to the Transfer Notice, or if it elects to purchase such assets, but
fails to close the purchase thereof within the period specified in the preceding
sentence, then the Company may, within one hundred twenty (120) days following
delivery of the Transfer Notice, transfer such assets to the Offeror on the
terms and conditions contained in the Transfer Notice. Any proposed transfer on
terms and conditions materially more favorable to the Offeror than those
described in the Transfer Notice, as well as any proposed transfer by the
Company after the expiration of such 120-day period, shall again be subject to
the Answering Service Right of First Refusal and shall require compliance by the
Company with the procedure described in this Article 8.

     8.5  Non-Cash Consideration.  In the event the consideration proposed to be
          ----------------------                                                
paid by the Offeror as described in the Transfer Notice includes non-cash
consideration, the Transfer Notice shall state the fair market value thereof.
Purchaser may, within ten (10) business days after delivery of the Transfer
Notice to it, by written notice to the Company, challenge such valuation by
specifying Purchaser's valuation of such non-cash consideration.  In the event
of such a challenge, the Company and Purchaser shall agree upon one independent
appraiser, who shall determine the fair market value of the non-cash
consideration for these purposes.  In the even that such parties are unable to
agree upon such an appraiser, the parties agree that the American Arbitration
Association ("AAA") shall be employed to choose an independent appraiser and
shall use their best efforts to cause AAA to designate an independent appraiser
within a maximum of fourteen (14) days, and such person shall promptly determine
the fair market value of the non-cash consideration for these purposes.  In the
event the appraisal process is utilized, (a) the party whose valuation of the
shares less closely approximates the value determined by the appraiser, measured
by dollar amounts and not by percentages, shall pay all costs of the independent
appraiser and (b) the relevant time periods for the exercise of the Right of
First Refusal and for the consummation of any transfer pursuant to Section 8.3
or 8.4 shall be tolled from the time Purchaser challenges the Company's
valuation of the non-cash consideration until the independent appraiser
determines the fair market value thereof.  In the event that the Answering
Service Right of First Refusal is exercised, Purchaser shall pay cash to the
Company in lieu of said non-cash consideration equal to the fair market value of
such non-cash consideration as determined in accordance with this Section 8.5.

9.   RIGHT OF FIRST REFUSAL -- NEW SECURITIES.

     9.1  New Securities Defined.  "New Securities" shall mean any common stock
          ----------------------

consultants of the Company or any subsidiary thereof pursuant to a stock option
plan or agreement approved by the Company's Board of Directors; provided, that
such stock options thereunder, if granted after the Closing Date, are granted at
a price that the Company's Board of Directors determines in good faith is not
less than the fair market value of the securities into which they are
exercisable as of the date of grant;

          9.1.5  any conversion into Common Stock pursuant to the Company's
Articles of Incorporation (as amended by the Charter Amendment);

          9.1.6  the purchase by Matria Healthcare, Inc. of up to 134,000 shares
of Preferred Stock at a purchase price of no less than $15.00 per share and, for
no additional consideration, a warrant for the purchase of up to 60,000 shares
of Preferred Stock; or

          9.1.7  up to 300,000 shares of Common Stock Series D of the Company
issued at any time following the Closing Date pursuant to options to purchase
shares of such stock in favor of officers, employees or consultants of the
Company or any subsidiary thereof pursuant to bona fide commitments made by the
Company prior to July 1, 1998.

     9.2  Exercise of Right.  In the event the Company proposes to undertake an

issuance of New Securities prior to the occurrence of an Initial Public
Offering, it shall give Purchaser written notice of its intention, describing
the type of New Securities, the price, the closing date of the offering thereof,
and the general terms upon which the Company proposes to issue the same.
Purchaser shall be entitled at any time during the offering of the New
Securities to purchase some or all of its pro rata portion of such New
Securities for the price and upon the general terms specified in the notice (and
in any case at a price and upon general terms no more favorable to any of the
other purchasers in such offering), by giving, within ten (10) business days
after receiving such notice from the Company, written notice to the Company of
such election stating therein the time and place of the closing of such
purchase, which must be a date no later than ten (10) days following the closing
date of the offering specified in the notice given by the Company or any
extended closing date thereof.  For 

                                       20


 
purposes of this Section 9.2, Purchaser's pro rata portion of New Securities
shall be equal to a fraction, the numerator of which is the sum of

           (i)  the number of shares of Common Stock into which shares of
     Preferred Stock held by Purchaser immediately prior to such issuance have
     been converted since the Preferred Stock was issued to Purchaser, and

           (ii) the number of shares of Common Stock into which Purchaser's
     shares of Preferred Stock could be converted if fully converted immediately
     prior to such issuance,

and the denominator of which is the sum of

           (y)  the number of shares of Common Stock of all series actually
     outstanding immediately prior to such issuance and

           (z)  the number of shares of Common Stock of all series into which
     the then outstanding shares of Preferred Stock could be converted or
     exercised if fully converted or exercised immediately prior to such
     issuance.

     9.3  Non-Conforming Offers.  Any offer by the Company of securities in
          ---------------------                                            
addition to those specified in the notice described in Section 9.1 above,
whether on the same or different terms as are specified therein, shall again
require compliance by the Company with the terms of this Article 9.

10.  PROVISION FOR PERFORMANCE-BASED WARRANT.

     Following the Closing Date, the Company and Purchaser shall continue to
negotiate in good faith to enter into a joint product marketing or strategic
alliance agreement with respect to the Company's Internet-based information and
communications services operations and certain of Purchaser's own Internet-based
products and services (the "Strategic Alliance Agreement").  If, and only if,
Purchaser and the Company enter into the Strategic Alliance Agreement within
ninety (90) days following the Closing Date, the Company shall issue to
Purchaser, for no additional consideration, within five (5) days following the
execution by the parties of the Strategic Alliance Agreement, a performance-
based warrant to purchase an aggregate of *** shares of Preferred Stock or, in
the event that the Initial Public Offering has been closed by such  date, Common
Stock (the "Performance-Based Warrant").  The Performance-Based Warrant would be
granted with respect to ***, *** and *** shares on December 31 of each of the
calendar years 1998, 1999 and 2000, respectively, with the exercise price per
share equal to the fair market value of the underlying capital stock on the
respective dates of grant (as adjusted for stock splits, stock dividends,
combinations and the like occurring after the date thereof) provided that the
joint marketing efforts of Purchaser and the Company yielded the Company gross
revenues of  $***, $*** and $***, respectively, during such years.  Such
Performance-Based Warrant shall otherwise contain terms substantially similar to
those of the 





***  Omitted pursuant to a request for confidential treatment and filed
separately with the Commission.

                                       21

     ------------------                                               
commissions and stock transfer taxes applicable to the sale of Registrable
Securities and any other securities of the Company being sold in the same
registration as the Registrable Securities by Other Shareholders.

     "Warrant Shares" shall have the meaning set forth in Section 3.5 hereof.

     11.2  Requested Registration.
           ---------------------- 

           11.2.1  Demand Registration Rights.  Subject to the conditions of
                  --------------------------                               
Subsection 11.2.2 below, the Initiating Holders may make up to two (2) demands
on the Company to register all or a portion consisting of at least 200,000
shares of the Registrable Securities on Form S-1 or such other form that may be
available to the Company to effect such demand registration and up to four (4)
demands on the Company to register all or a portion consisting of at least
200,000 shares  of the Registrable Securities on Form S-3, if available (each
being referred to hereinafter as a "Demand Registration"); provided, however,
that, the Initiating Holders may not initiate a demand on the Company to
register any Registrable Securities until (i) the first anniversary of the
Closing Date, if a registration statement filed with the Commission with respect
to the Initial Public Offering is not declared effective prior to such
anniversary; or (ii) after the date that is six (6) months following the
effective date of the registration statement relating to the Initial Public
Offering if such effective date occurs prior to the first anniversary of the
Closing Date.  Notwithstanding the foregoing, if an offering required pursuant
to this Section 11.2 would constitute the initial offering to the public of the
securities of the Company, then such offering may only be made by means of an
underwritten public offering (either firm or best efforts), provided that in the
event that neither the Company nor the Initiating Holders have secured an
underwriter reasonably acceptable to the other entity or group for such purpose
during the one hundred eighty (180)-day period after the Company's receipt of
the request for registration from the Initiating Holders, then the Company shall
promptly file a registration statement pursuant to Rule 415 under Regulation C
promulgated under the Securities Act covering the Registrable Securities
described in the Initiating Holder's request.

           11.2.2  Request for Registration.  In the event the Company shall
                   ------------------------                                 
receive from the Initiating Holders a written request that the Company effect a
Demand Registration with respect to all or a portion consisting of at least
200,000 shares of the Registrable Securities, other than a registration pursuant
to Rule 415 under Regulation C promulgated under the Securities Act, the Company
shall:

                   (i)  promptly give written notice of the proposed
           registration to all other Holders; and

                   (ii) as soon as practicable, use its diligent best efforts to
           effect such registration (including, without limitation, the
           execution of an undertaking to file post-effective amendments,
           appropriate qualification under applicable "blue sky" or other state
           securities laws, and appropriate 

                                       23


 
           compliance with applicable regulations issued under the Securities
           Act) as may be so requested and as would permit or facilitate the
           sale and distribution of such portion of such Registrable Securities
           as is specified in such request, together with such portion of the
           Registrable Securities of any Holder or Holders joining in such
           request as is specified in a written request given within twenty (20)
           days after receipt of such written notice from the Company; provided
           that the Company shall not be obligated to take any action to effect
           any such registration pursuant to this Section 11.2 in any particular
           jurisdiction in which the Company would be required to execute a
           general consent to service of process in effecting such registration,
           qualification or compliance unless the Company is already subject to
           service in such jurisdiction and except as may be required by the
           Securities Act.

     In the event the Company is not obligated to effect any requested
registration by virtue of the foregoing, such request shall not be deemed to be
a Demand Registration for purposes of Subsection 11.2.1.  Subject to the
foregoing, the Company shall file a registration statement covering the
Registrable Securities so requested to be registered as soon as practicable
after receipt of the request of the Initiating Holders.  Notwithstanding the
foregoing provisions of this Section 11.2.2, the Company's obligation to file a
registration statement hereunder shall be suspended for a period not to exceed
ninety (90) days and no more than once during any period of twelve (12)
consecutive months if there exists at the time material non-public information
relating to the Company that, in the reasonable opinion of the Company, should
not be disclosed or if the filing of such registration statement would, in the
opinion of the Board of Directors of the Company, arrived at in good faith,
adversely affect the Company, a material financing project or a material
proposal or pending acquisition, merger or other corporate reorganization to
which the Company is then, or is then expected to become a party.

     The registration statement filed pursuant to the request of the Initiating
Holders may, subject to the provisions of Subsection 11.2.3 below, include
securities offered by the Company for its own account and/or other securities of
the Company that are held by Other Shareholders.

          11.2.3  Underwriting.  If the Initiating Holders intend or are
                  ------------                                          
required to distribute the Registrable Securities covered by their request by
means of an underwriting, they shall so advise the Company as a part of their
request made pursuant to Subsection 11.2.1 and the Company shall include such
information in the written notice referred to in Subsection 11.2.2(i) hereof.
The right of any Holder to registration pursuant to this Section 11.2 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.

     If the Company shall request inclusion in any registration pursuant to
Section 11.2 of securities being sold for its own account, or if Other
Shareholders shall request inclusion in any registration pursuant hereto, then,
subject to the last sentence of this Subsection 11.2.3 with respect to the
Company's request, the Initiating Holders shall, on behalf of all Holders,
include such securities in the underwriting and may condition such offer on
their acceptance of 

                                       24


 
the further applicable provisions of this Article 11. The Company shall
(together with all Holders and Other Shareholders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form and containing customary terms reasonably acceptable to the
Initiating Holders, with the representative of the underwriter or underwriters
selected for such underwriting by the Company and reasonably acceptable to the
Initiating Holders; provided, however, that if the Company has not selected an
underwriter reasonably acceptable to the Initiating Holders within thirty (30)
days after the Company's receipt of the request for registration from the
Initiating Holders, then the Initiating Holders may select an underwriter
reasonably acceptable to the Company in connection with such registration.
Notwithstanding any other provision of this Section 11.2, if the underwriter
representative advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, the securities
of the Company held by Other Shareholders shall first be excluded from such
registration to the extent so required by such limitation, and, to the extent
additional shares need to be excluded in order to conform to such limitation,
the securities requested by the Company to be included, if any, shall next be
excluded. The Company shall advise all holders of securities requesting
registration as to the number of shares of securities that may be included in
the registration and underwriting as allocated in the foregoing manner. If any
Other Shareholder or Holder who has requested inclusion in such registration as
provided above disapproves of the terms of the underwriting, such person may
elect to withdraw therefrom by written notice to the Company, the underwriter
and the Initiating Holders. The securities so withdrawn shall also be withdrawn
from registration. If the underwriter has not limited the number of shares to be
underwritten, the Company may include its securities for its own account in such
registration if the underwriter so agrees and if the number of Registrable
Securities and other securities of the Holders that would otherwise have been
included in such registration and underwriting will not be limited thereby.

     11.3 Company Registration.
          -------------------- 

          11.3.1  If the Company shall determine to register any of its
securities in connection with the public offering of such securities solely for
cash on a form that would permit the registration of the Registrable Securities
other than on Form S-8, Form S-4 or another form not available for registering
the Registrable Securities for sale to the public, the Company shall promptly
give to each Holder written notice of such registration (a "Piggyback
Registration"), and shall include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made by any Holder or Holders within fifteen (15) days after
receipt of such written notice from the Company, subject to the underwriter
limitations, if any, described in Subsection 11.3.4 hereof; provided, however,
that no Holder shall have the right to participate in an Initial Public Offering
pursuant to a registration statement declared effective within the twelve (12)-
month period following the Closing Date.  The Company shall have the right to
withdraw or cease to prepare or file any registration statement for any offering
referred to in this Subsection 11.3.1 without any obligation or liability to any
Holder.

                                       25


 
          11.3.2  Number of Piggyback Registrations.  Subject to the underwriter
                  ---------------------------------                             
limitations, if any, described in Subsection 11.3.4  below, each Holder shall be
entitled to have its Registrable Securities included in an unlimited number of
Piggyback Registrations pursuant to this Section 11.3 until such time as the
number of Registrable Securities held by any such Holder does not exceed one
percent (1%) of the shares outstanding of the Company as shown by the most
recent report or statement published by the Company and filed with the
Commission.

          11.3.3  Holdback by the Company.  If the Company has previously filed
                  -----------------------                                      
a registration statement with respect to Registerable Securities pursuant to
Section 11.2 or pursuant to this Section 11.3, and if such previous registration
has not been withdrawn or abandoned, the Company will not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-4, Form S-8 or any successor forms),
whether on its own behalf or at the request of any Holder or Holders, until a
period of ninety (90) days has elapsed from the effective date of such a
previous registration.

          11.3.4  Underwriting.  If the registration of which the Company gives
                  ------------                                                 
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Subsection 11.3.1 hereof.  In such event the right of any Holder to
registration pursuant to Subsection 11.3.1 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.  All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and Other Shareholders distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for underwriting by the
Company. Notwithstanding any other provision of this Section 11.3, if the
underwriter reasonably determines that marketing factors require a limitation on
the number of shares to be underwritten, such reduction in the number of shares
that may be included in the registration shall be made (a) first, to the shares
of the Holders and Other Shareholders requesting registration of securities
pursuant to piggyback registration rights; (b) second, to the shares of the
Company, and (c) third, to the shares of any person other than the Holders
requesting registration of securities pursuant to demand registration rights;
all in proportion, as nearly as practicable, to the respective amounts of
Registrable Securities and other securities that such person, Holders and Other
Shareholders had requested to be included in such registration; provided,
however, that in no event shall the total amount of Purchaser's shares of
securities included in the offering pursuant to a Piggyback Registration be less
than the number of securities included in the offering by any other single
selling shareholder pursuant to piggyback registration rights unless all of
Purchaser's shares of securities are included in the offering.  The Company
shall advise all holders of securities requesting registration as to the number
of shares or securities that may be included in the registration and
underwriting as allocated in the foregoing manner.  No such reduction shall be
made with respect to securities offered by the Company for its own account.  If
any Holder or Other Shareholder disapproves of the terms of any such
underwriting, such person may elect to withdraw therefrom by written 

                                       26


 
notice to the Company and the underwriter. Any Registrable Securities or other
securities excluded or withdrawn from such underwriting shall also be withdrawn
from such registration.

     11.4  Expenses of Registration.  All Registration Expenses incurred in
           ------------------------                                        
connection with any registration, qualification or compliance pursuant to this
Agreement shall be borne by the Company; and all Selling Expenses shall be borne
by the Holders, the Other Shareholders of the securities so registered and the
Company, to the extent of securities registered on its behalf, pro rata on the
basis of the number of their shares so registered; provided, however, that the
Company shall not be required to pay any Registration Expenses if, as a result
of the withdrawal of a request for registration by the Initiating Holders
pursuant to Section 11.2 hereof, the registration statement does not become
effective, in which case the Holders and Other Shareholders requesting
registration shall bear such Registration Expenses pro rata on the basis of the
number of their shares so included in the registration request (except for the
fees of any counsel for the Holders, which shall be borne only by the persons
whom such counsel represented, pro rata on the basis of the number of their
shares so included in the registration request); provided, further, that such
registration shall not be counted as a Demand Registration pursuant to
Subsection 11.2.1 hereof; and provided, further, that if any jurisdiction in
which the securities shall be qualified shall require that expenses incurred in
connection with the qualification of the securities in that jurisdiction be
borne by the selling shareholders, then such expenses shall be payable by the
selling shareholders pro rata to the extent required by such jurisdiction.

     11.5  Registration Procedures.  In the case of each registration effected
           -----------------------                                            
by the Company pursuant to this Agreement, the Company shall keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. At its expense the Company shall use its best efforts to:

           11.5.1  keep such registration effective for a period of one hundred
eighty (180) days or until the Holder or Holders have completed the distribution
described in the registration statement relating thereto, whichever first
occurs; and

           11.5.2  furnish such number of prospectuses and other documents
incident thereto as a Holder from time to time may reasonably request.

     11.6  Indemnification.
           --------------- 

           11.6.1  With respect to each Holder whose securities have been
registered pursuant to this Agreement, the Company shall indemnify such Holder,
each of such Holder's officers, directors and partners, and each person
controlling (as defined in Subsection 11.6.4 below) such Holder and each of such
controlling person's officers, directors and partners, and shall also indemnify
each underwriter, if any, and each person who controls any underwriter, against
all claims, losses, damages and liabilities (or actions in respect thereof)
arising out of or based on (a) any untrue statement (or alleged untrue
statement) of a material fact contained in any prospectus, offering circular or
other document (including any related registration statement, notification or
the like) incident to any such registration, qualification or 

                                       27


 
compliance, (b) any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, or (c) any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration, qualification or compliance, and shall reimburse each such Holder
and each person controlling such Holder, and each of such controlling person's
officers, directors and partners, each of its officers, directors and partners,
each such underwriter, and each person who controls such underwriter, for any
legal and other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action; provided, however,
that the Company shall not be liable in any such case to the extent that any
such claim, loss, damage, liability or expense arises out of or is based upon
written information furnished to the Company by such Holder or on behalf of such
Holder by the officers, directors or partners of such Holder seeking to be
indemnified, where such information is stated to be specifically for use in such
prospectus, offering circular or related document.

          11.6.2  Each Holder and Other Shareholder shall, if securities held by
him or it are included among the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
(as defined in Subsection 11.6.4 below) the Company or such underwriter, and
each other such Holder and Other Shareholder and each of such controlling
person's officers, directors and partners, and each person controlling such
other Holder or Other Shareholder and each of such controlling person's
officers, directors and partners, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and shall reimburse the Company, such other Holders, Other
Shareholders, directors, officers, partners, persons, each underwriter and each
person who controls such underwriter for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by such Holder or
Other Shareholder specifically for use therein; provided, however, that the
obligations of such Holder or Other Shareholder hereunder shall be limited to an
amount equal to the proceeds to such Holder or Other Shareholder of securities
sold as contemplated herein.

          11.6.3  Each party entitled to indemnification under this Section 11.6
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for 

                                       28


 
the Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not be withheld unreasonably). The Indemnified Party may
participate in such defense with counsel of its own choosing, but the fees and
expenses of such counsel shall be at such Indemnified Party's expense unless (i)
the Indemnifying Party and the Indemnified Party shall have agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party and representation of both parties by the same counsel would
be inappropriate due to actual or potential conflicting interests between them.
The failure of any Indemnified Party to give notice as provided herein shall
relieve the Indemnifying Party of its obligations under this Section 11.6 only
if such failure is prejudicial to the ability of the Indemnifying Party to
defend such action, and such failure shall in no event relieve the Indemnifying
Party of any liability that he or it may have to any Indemnified Party otherwise
than under this Section 11.6. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability with respect to such
claim or litigation.

           11.6.4  For purposes of this Section 11.6, the term "control" shall
have the meaning assigned thereto under the Securities Act.

     11.7  Information by Holders and Other Shareholders.  Each Holder or Other
           ---------------------------------------------                       
Shareholder of securities included in any registration shall furnish to the
Company such information regarding such Holder or Other Shareholder and the
distribution  proposed by such Holder or Other Shareholder as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Agreement.

     11.8  Limitations on Registration of Issues of Securities.  From and after
           ---------------------------------------------------                 
the date of this Agreement, without the consent of the holders of a majority of
the Registrable Securities then issued and outstanding and that are issuable
upon the exercise of the Warrant, the Company shall not enter into any
agreements with any holder or prospective holder of any securities of the
Company that, upon any registration of any of its securities, the Company will
include among the securities that it then registers securities owned by such
holder or prospective holder except to the extent such agreement could give such
holder or prospective holder rights no greater than those of an Other
Shareholder under this Article 11.  In any event, any registration rights given
by the Company to any holder or prospective holder of its securities shall not
conflict with the registration and other rights provided in this Agreement.

     11.9  Rule 144 Reporting.  With a view to making available the benefits of
           ------------------                                                  
certain rules and regulations of the Commission that may permit the sale of the
Common Stock to the public without registration, the Company shall, for so long
as Registrable Securities are outstanding:

                                       29


 
            11.9.1  make and keep public information available, as those terms
are understood and defined in Rule 144 promulgated by the Commission under the
Securities Act ("Rule 144"), at all times after ninety (90) days following the
Initial Public Offering;

            11.9.2  file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Securities Exchange Act at any time after it has become subject to the reporting
requirements thereunder; and

            11.9.3  so long as any Holder owns any securities constituting or
representing Registrable Securities, furnish to such Holder forthwith upon
request a written statement by the Company as to its compliance with the
reporting requirements of Rule 144 (at any time after ninety (90) days following
the Initial Public Offering), and of the Securities Act and the Securities
Exchange Act (at any time after it has become subject to the reporting
requirements thereunder), a copy of the most recent annual or quarterly report
of the Company, and such other reports and documents so filed by the Company as
such Holder may reasonably request in availing itself of any rule or regulation
of the Commission allowing such Holder to sell any such securities without
registration.

     11.10  Transfer of Registration Rights.  The rights to cause the Company to
            -------------------------------                                     
register securities of the Company under Sections 11.2 and 11.3 hereof may be
assigned by any Holder to any transferee of Registrable Securities together with
the securities being transferred, provided that in each case the Company is
given written notice, at the time or within a reasonable time after said
transfer, stating the name and address of said transferee and identifying the
securities with respect to which such registration rights are being assigned;
provided, however, that such transfer right shall be subject to the provisions
of Section 12.3 hereof.  No such assignment shall be effective unless the
transferee shall be required, as a condition to such transfer, to agree in
writing that he or it will receive and hold such securities subject to the
provisions of this Article 11.

     11.11  "Market Stand-Off" Agreement.  If requested by the Company upon the
            ----------------------------                                       
recommendation of the Board of Directors of the Company and an underwriter of
Common Stock  (or other securities) of the Company, the Holders shall not sell
or otherwise transfer or dispose of any Common Stock (or other securities) of
the Company held by them during the one hundred eighty (180)-day period
following the effective date of a registration statement of the Company filed
under the Securities Act, provided that:

            (a)  such agreement shall apply only with respect to an underwritten
Initial Public Offering; and

            (b)  Other Shareholders selling securities pursuant to such
registration statement and all officers and directors of the Company enter into
similar agreements.

     Such agreement shall be in writing in form satisfactory to the Company and
such underwriter.  The Company may impose stop-transfer instructions with
respect to the shares 

                                       30


 
(or securities) subject to the foregoing restriction until the end of said one
hundred eighty (180)-day period.

12.  MISCELLANEOUS.

     12.1  Governing Law.  This Agreement shall be governed by and construed
           -------------                                                    
under the laws of the State of Georgia, without regard to its principles of
conflicts of laws.

     12.2  Survival.  The representations, warranties, covenants and agreements
           --------                                                            
made herein shall survive any investigation made by Purchaser and the closings
of the transactions contemplated hereby.

     12.3  Successors and Assigns.

           (a)  Except as otherwise expressly provided in this Section 12.3, the
provisions of this Agreement shall inure to the benefit of, and be binding upon,
the successors, assigns, heirs, executors and administrators of the respective
Purchaser, and the rights, remedies and entitlements of the respective Purchaser
under this Agreement may be assigned in full or in part at any time after the
date of this Agreement together with the entire Warrant or no fewer than 200,000
shares of Preferred Stock or Conversion Shares constituting or derived from the
Purchased Shares, the Warrant Shares, or the Additional Shares.  No such
assignment shall be effective unless (i) the transferee shall be required, as a
condition to such transfer, to agree in writing that he or it will receive and
hold the Purchased Shares subject to the applicable provisions of this Agreement
and the Shareholders' Agreement referred to in Sections 5.6 and 6.3 hereof, (ii)
the Company is given written notice at the time of the assignment or within a
reasonable time after such assignment, stating the name and address of said
transferee and identifying the Purchased Shares that are being assigned, or
(iii) the Company has received the written opinion of counsel to the Company
that such transfer is permitted under the federal securities laws, rules and
regulations.

           (b)  Purchaser covenants and agrees that it shall not transfer the
Warrant, the Warrant Shares, the Purchased Shares, the Additional Shares or the
Conversion Shares (collectively, the "Purchased Securities") to any of the
entities listed in Exhibit 12.3 attached hereto, or to any entity or person that
                   ------------                                                 
controls or is controlled by an entity listed in Exhibit 12.3 ("control" being
                                                 ------------                 
defined for such purpose as ownership of at least a majority of the voting
interests of the entity), unless the proposed transfer has been approved by the
Company's Board of Directors.

           (c)  In the event Purchaser proposes to sell, transfer or otherwise
dispose of any of the Purchased Securities (the "Subject Securities") to any
entity that is under common control (as the term "control" is defined in Section
12.3(b) above) with an entity listed in Exhibit 12.3 hereto (a "Sister Entity"),
                                        ------------                            
the Company shall have a right of first refusal to purchase all, but not less
than all, the Subject Securities that Purchaser proposes to transfer to such
Sister Entity (the "Subject Securities Right of First Refusal").  Before
effecting any proposed transfer of any Subject Securities, Purchaser shall give
written notice to the Company 

                                       31


 
describing fully the proposed transfer, including the type and number of Subject
Securities, the name and address of the proposed transferee(s) and the proposed
transfer price, and the fair market value of any proposed non-cash consideration
as provided in Section 12.3(d) hereof (the "Transfer Notice"). The Transfer
Notice shall contain an accurate summary of the offer of the proposed
transferee(s), which must be a bona fide offer. At any time within the ten (10)-
day period immediately following the receipt of the Transfer Notice, the Company
may elect to purchase all, but no fewer than all, of the Subject Securities at
the price per share set forth in the Transfer Notice. The closing of any sale
and purchase of the Subject Securities pursuant to exercise of the Subject
Securities Right of First Refusal shall be held at the offices of the Company on
a date and at a time designated by the Company in its notice of exercise of the
Subject Securities Right of First Refusal; but in no event shall such closing be
held more than thirty (30) days after delivery of the Transfer Notice. If the
Company fails to exercise the Subject Securities Right of First Refusal in a
timely manner as to all the Subject Securities upon the terms set forth in the
Transfer Notice, or if it elects to purchase all such Subject Securities, but
fails to close the purchase thereof within such 30-day period, then Purchaser
may transfer all the Subject Securities on the terms and conditions described in
the Transfer Notice. Any proposed transfer on terms and conditions materially
different from those described in the Transfer Notice shall again be subject to
the Subject Securities Right of First Refusal and shall require compliance by
Purchaser with the procedure described in this Section 12.3(c).

          (d)  In the event the consideration proposed to be paid to Purchaser
as described in the Transfer Notice referred to in Section 12.3(c) hereof
includes non-cash consideration, the Transfer Notice shall state the fair market
value thereof, which valuation shall be conclusive and binding on the Company in
the absence of a timely challenge made in accordance with this Section 12. The
Company, may, within ten (10) days after delivery of the Transfer Notice to the
Company, by written notice to Purchaser, challenge such valuation, such notice
to specify the Company's valuation of such non-cash consideration. In the case
of such a challenge, Purchaser and the Company shall agree upon one independent
appraiser, who shall determine the fair market value of the non-cash
consideration for these purposes. In the event that such parties are unable to
agree upon such an appraiser, the parties agree that the American Arbitration
Association ("AAA") shall be employed to choose an independent appraiser and
shall use their best efforts to cause AAA to designate an independent appraiser
within a maximum of fourteen (14) days, and such person shall promptly determine
the fair market value of the non-cash consideration for these purposes. In the
event the appraisal process is utilized, (i) the party whose valuation of the
shares less closely approximates the value determined by the appraiser, measured
by dollar amounts and not by percentages, shall pay all costs of the independent
appraiser and (ii) the relevant time periods for the exercise of the Subject
Securities Right of First Refusal and for the closing of exercising such right
shall be tolled from the time a challenge is made to Purchaser's valuation of
the non-cash consideration until the independent appraiser determines the fair
market value thereof. In the event the Company exercises the Subject Securities
Right of First Refusal, it shall pay cash to Purchaser in lieu of said non-cash
consideration equal to the fair market value as determined in accordance with
this Section 12.3(d).

                                       32

certificate, report or other instrument delivered under or pursuant to any term
hereof shall be untrue or misleading in any material respect as of the date of

                                                                   EXHIBIT 10.18

                                                                                
                       AMENDMENT TO INVESTMENT AGREEMENT
                       ---------------------------------

          THIS AMENDMENT TO INVESTMENT AGREEMENT (this "Amendment"), dated as of
the 23rd day of October, 1998, is made by and between WebMD, INC., a Georgia
corporation (formerly known as Endeavor Technologies, Inc., the "Company"), and
HBO & COMPANY OF GEORGIA, a Delaware corporation (the "Purchaser").

                              W I T N E S S E T H:
                              - - - - - - --- - - 

          WHEREAS, the Company and Purchaser are parties to that certain
Investment Agreement dated as of August 24, 1998 (the "Agreement"); and

          WHEREAS, the Company and Purchaser desire to amend the Agreement as
provided in this Amendment.

          NOW, THEREFORE, in consideration of the mutual covenants and
agreements hereinafter set forth, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and
Purchaser hereby agree as follows:

     1.   Section 2.3 of the Agreement is hereby amended to read in full as
follows:

          "2.3  Issuance of Additional Shares.  The parties acknowledge that the
                -----------------------------                                   
Company may make an initial offering to the public of its Common Stock pursuant
to a registration statement effective under the federal Securities Act of 1933,
as amended (the "Securities Act"), following the Closing Date (the closing of
such offering being referred to hereinafter as the "Initial Public Offering").
If the Company does not close the Initial Public Offering at an offering price
of at least $18.00 per share (as adjusted for any stock splits, stock dividends,
combinations or the like) on or before the date that is two hundred seventy
(270) days following the Closing Date, the Company shall issue for no additional
consideration to Purchaser 150,000 additional shares of Preferred Stock without
need for any further action by Purchaser; provided that if the Company closes
the Initial Public Offering within such 270-day period, but does so at an
offering price less than $18.00 per share (as adjusted for any stock splits,
stock dividends, combinations or the like), such shares shall consist of Common
Stock rather than Preferred Stock.  Furthermore, in the event the Company fails
to close the Initial Public Offering on or before the date that is 90 days
following the first anniversary of the Closing Date, the Company shall issue
promptly to Purchaser, for no additional consideration, an additional 50,000
shares of Preferred Stock without need for any further action by Purchaser.  The
numbers of shares of stock specified in this Section 2.3 shall be adjusted for
any stock splits, stock dividends, recapitalizations or similar events occurring
prior to the dates indicated."

     2.   Section 10 of the Agreement is hereby amended to read in full as
follows:

          "10.  PROVISION FOR PERFORMANCE-BASED WARRANT.

          Following the Closing Date, the Company and Purchaser shall continue
to negotiate in good faith to enter into a strategic distribution alliance
agreement with respect to the Purchaser's distribution of the Company's
Internet-based information and communications 


 
services (the "Strategic Alliance Agreement"). If, and only if, the Purchaser
and the Company enter into the Strategic Alliance Agreement within ninety (90)
days following the Closing Date, the Company shall issue to Purchaser, for no
additional consideration, within five (5) days following the execution by the
parties of the Strategic Alliance Agreement, a performance-based warrant to
purchase an aggregate of *** shares of Preferred Stock or, in the event that the
Initial Public Offering has been closed by such date, Common Stock (the
"Performance-Based Warrant"). The Performance-Based Warrant would be granted
with respect to ***, *** and *** shares on March 31 of each of the calendar
years 1999, 2000 and 2001, respectively, with the exercise price per share equal
to the fair market value of the underlying capital stock on the respective dates
of grant (as adjusted for stock splits, stock dividends, combinations and the
like occurring after the date thereof) provided that the joint marketing efforts
of Purchaser and the Company yielded the Company gross revenues of $***, $***
and $***, respectively, during the twelve-month period ending on March 31 of
