as of the 12th day of May, 1999, between WebMD, Inc., a Georgia corporation (the
"Company"), Microsoft Corporation, a Washington corporation (the "Microsoft"),

         1.1      Authorization. The Company has authorized the sale and

Exhibit 1.1 attached hereto.

         1.2      Sale of Shares. Subject to the terms and conditions hereof,

employees not expressly terminable at will and no collective bargaining
agreements covering any of its employees. Further, neither the Company nor any
subsidiary thereof has any policies, procedures or handbooks providing for other
than at-will employment. No employee, agent, consultant or contractor associated
with any of the members of management or key personnel of the Company or its
subsidiaries who has contributed to or participated in the conception and
development of proprietary rights, including software, of the Company or its
subsidiaries has asserted or threatened any claim against the Company or the
applicable subsidiary in connection with such person's involvement in the

affecting the Company's and its subsidiaries' current or prospective operations.
The Company and its subsidiaries are in compliance in all material respects with
all applicable laws respecting employment and employment practices, occupational

to register any of its presently outstanding securities or any of its securities
that may hereafter be issued pursuant to this or any other existing agreement,

the Securities and Exchange Commission (the "Commission") and other filings
required by the blue sky laws of the states where the Investors are located, no
consent, approval or authorization of, or registration, declaration,

         4        REPRESENTATIONS AND WARRANTIES OF THE INVESTORS.

         Each of the Investors, severally and not jointly, represents and
warrants to the Company, as of any of the Closing Dates on which such Investor
purchases Purchased Shares, as follows:

         4.1      Access to Information.

                  4.1.1    Such Investor acknowledges that the Company filed a
Registration Statement on Form S-1 (No. 333-71359) with the Commission on
January 28, 1999, which was amended on February 26, 1999, with respect to the
initial public offering of the Company's Common Stock (the "Registration
Statement"). Prior to any Investor (other than Microsoft) becoming a Purchaser
hereunder, the Company shall withdraw such Registration Statement. Microsoft
acknowledges that it had commenced discussions with the Company prior to the
filing of the Registration Statement which discussions resulted directly in this
Agreement and the other agreements between Microsoft and the Company
contemplated by the Master Agreement. Each Purchaser represents and warrants
that it became aware of the Company and the opportunity to become a Purchaser
hereunder through Microsoft and not as a result of the Registration Statement or
any advertising, news articles, internet chat rooms or other means of general
solicitation . Each Investor represents that while it may have reviewed the
Registration Statement, it has not relied on the Registration Statement for
purposes of making its investment hereunder, but rather has had the opportunity
to perform its own independent due diligence review of the Company and such
Investor and its advisor or advisors, or a person or persons acting on its
behalf, has had a reasonable opportunity to ask questions of and receive answers
from the officers of the Company, concerning the business and financial
condition of the Company and the terms and conditions of the offering of the
Purchased Shares, and to obtain additional information, to the extent possessed
or obtainable without unreasonable effort or expense by the officers of the
Company. All such questions have been answered to the full satisfaction of such
Investor. Microsoft acknowledges that the opportunity to enter into the Cross
Promotion Agreement with the Company was an integral 



                                       12
>PAGE>   13

part of its decision to purchase the Purchased Shares. Each Purchaser
acknowledges that the opportunity to enter into a strategic operating agreement
with the Company was an integral part of its decision to purchase the Purchased
Shares. In addition, each Purchaser acknowledges that it has not relied on any
due diligence, representations or other information or advice from Microsoft in
making its investment decision to purchase the Purchased Shares hereunder.

         4.1.2    Such Investor acknowledges that, from time to time, statements
about the Company may be made by third parties, in writing or otherwise, that
may purport to contain information about the Company, including in newspaper
articles, internet chat rooms and, except as provided below, other publications
and communications, and that such statements have been and may be incorrect or
inaccurate in several material respects. Such Investor agrees that neither the
Company nor any of its affiliates or representatives has made any representation
or warranty as to the accuracy or completeness of any such information or
statements. Furthermore, such Investor has not relied, and will not rely, upon
any such statements in making any investment decision in connection with the
Purchased Shares; rather, the only representations or statements that such
Investor has relied upon or will rely upon will be those made by the Company in
the Registration Statement, as set forth in this Agreement, and in the following
parts of the Company's web site as it exists as of the date hereof: About WebMD
(other than Featured Topics and the Press Releases), Learn More about WebMD,
Meet our Strategic Partners, and Review our Products and Services.

         4.2      Experience; Investment. Such Investor is acquiring the
Purchased Shares solely for its own account, not as a nominee or agent, and not
with a view to, or for sale in connection with, any distribution thereof, as
that term is used under the Securities Act. Such Investor represents that such
Investor is an "accredited investor" within the meaning of Rule 501(a)(3) of
Regulation D promulgated by the Commission under the Securities Act and either
it or persons in control of its investment decision have assets in excess of
$100 million, and that it has been represented by counsel in connection with
this investment, and either it or persons representing it have considerable
experience in making investments of this nature.

         4.3      Registration under the Securities Act. Such Investor
understands that (a) neither the offering nor the sale of the Purchased Shares
has been registered under the Securities Act or applicable state securities
laws, in reliance upon exemptions from the registration provisions of the
Securities Act and applicable state securities laws, (b) the Purchased Shares
purchased by such Investor must be held by it indefinitely unless the sale or
transfer thereof is subsequently registered under the Securities Act and
applicable state securities laws or an exemption from such registration is
available, and the certificates or documents representing all Purchased Shares
will be legended to reflect such restrictions, (c) except as provided in the
Registration Rights Agreements between the Company and the Investors, the
Company is under no obligation to register any Purchased Shares, Conversion
Shares on such Investor's behalf or to assist it in complying with any exemption
from registration, and (d) the officers of the Company will rely in part upon
the representations and warranties made by such Investor in this Agreement in
order to establish such exemption from the registration provisions of the
Securities Act and applicable state securities laws.



                                       13
>PAGE>   14

         4.4      Transfer. Such Investor will not transfer any Purchased Shares
or Conversion Shares without registration under the Securities Act and
applicable state securities laws unless the transfer is exempt from registration
under the Securities Act and such laws and is made in compliance with the
legends contemplated by Section 8.10 herein.

         4.5      Authorization. All action on the part of such Investor
necessary for the authorization, execution, delivery and performance of all
obligations of such Investor under this Agreement or any document contemplated
hereby has been (or will be) taken prior to the Initial Microsoft Closing. This
Agreement, when executed and delivered by such Investor, will constitute the
valid and binding obligation of such Investor and is enforceable against it in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency or other laws affecting the enforcement of creditors'
rights generally, and except that the availability of the remedy of specific
performance or other equitable relief is subject to the discretion of the court
before which any proceeding therefor may be brought.

         7        COVENANTS.

         7.1      Basic Information. Subject to Section 7.2 hereof:

                  7.1.1    As soon as practicable after the end of each fiscal
year, and in any event within 90 days thereafter, beginning with the year ending
December 31, 1999, the Company shall furnish to the Investors audited
consolidated balance sheets of the Company and its subsidiaries, if any, as of
the end of such fiscal year and audited consolidated statements of income and
cash flow of the Company and its subsidiaries, if any, for such fiscal year,
prepared in accordance with GAAP consistently applied and setting forth in each
case in comparative form the figures for the previous fiscal year, all in
reasonable detail and certified by Ernst & Young, LLP or another independent
public accounting firm, which shall also be one of the six largest firms of
nationally recognized standing in the United States, or a firm acceptable to the
Investors.

                  7.1.2    As soon as practicable after the end of each fiscal
quarter, and in any event within 45 days thereafter, the Company shall furnish
to the Investors consolidated balance sheets of the Company and its
subsidiaries, if any, as of the end of such fiscal quarter, and consolidated
statements of income and cash flow of the Company and its subsidiaries, if any,
for such fiscal quarter and for the current fiscal year to date, prepared in
accordance with GAAP consistently applied, with such statements certified by the
chief financial officer of the Company as having been prepared in accordance
with GAAP consistently applied, and accompanied by a brief narrative description
of the Company's business activities during said quarter.

         7.2      Suspension of Certain Covenants. The covenants set forth in
Section 7.1 hereof, shall be suspended and be of no force or effect if the
Company becomes subject to the reporting requirements of the federal Securities
Exchange Act of 1934, as amended.

         7.3      Hart-Scott-Rodino.

                  7.3.1    In the event that, under the designations of the
Series E Preferred Stock contained in the Amendment to the Amended and Restated
Articles of Incorporation, any Investor would acquire the right to vote such
shares, because of the occurrence or nonoccurrence of a particular event, and
the acquisition of such right would require any filing by such Investor under
the Hart Scott Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), or the
acquisition or disposition by any Investor of the Conversion Shares would
require any such filing, then, before such voting right shall become effective,
either (1) the parties shall have been granted early termination of the waiting
period under the HSR Act, or (2) the applicable waiting period shall have
expired without any agency having sought injunctive relief with respect to the
effectiveness of the voting rights. Each of the Company and such Investors shall
cooperate in making any such filing promptly and shall furnish one another such
information and commercially reasonable assistance as necessary for any such
filing.

                  7.3.2    In the event that the Company enters into an
agreement that contemplates a Change of Control Transaction and, as a result,
filings under the HSR Act are required as a condition to the closing of such
transaction, then the Company and Microsoft covenant and 



                                       17

agree to cause the other party to the Change of Control agreement to covenant to
file the information and documents required by HSR and to condition or delay any
Change of Control until either (1) the parties shall have been granted early
termination of any waiting period under the HSR Act, or (2) the applicable
waiting period shall have expired without any agency having sought injunctive
relief. In the event that the applicable HSR waiting periods have not expired 90
days after the initial HSR filing, then Microsoft's right and obligation to
purchase Purchased Shares in the Additional Microsoft Purchase shall be
converted into a right and obligation to purchase an equivalent number of
nonvoting preferred stock that, by their terms, convert to voting common stock
and have such terms as may be mutually agreed by Microsoft and the Company and
an equivalent change shall be made to the consideration to be received with
respect to the Purchased Shares in such Change of Control Transaction.

         8        MISCELLANEOUS.

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

agreements made herein shall survive any investigation made by the Investors and
the closing of the transactions contemplated hereby.

         8.3      Assignment. This Agreement may not be assigned by any
Purchaser without the express written consent of the Company (which consent may
be granted or withheld in the sole discretion of the Company). This Agreement
may not be assigned by the Company without the express written consent of each
Investor except that the Company may assign this Agreement directly or
indirectly by operation of law in connection with a Change of Control if the
successor company or its parent company, which is a company whose securities are
registered pursuant to Section 12 of the Securities Exchange Act of 1934, as
amended, execute a joinder to this Agreement as of the closing of any Change of
Control. Notwithstanding the foregoing sentences, each Investor shall have the
right to assign its right to purchase any or all of the Purchased Shares to one
or more Authorized Transferees who agree to be bound by the terms and provisions
of this Agreement. As used herein, an "Authorized Transferee" of an Investor
shall mean a limited number of institutional accredited investors within the
meaning of Rule 501 promulgated under the Securities Act of 1933, as amended,
with gross assets in excess of $100,000,000 who became aware of the Company and
the opportunity to acquire Series E Preferred Stock and Series F Preferred Stock
as a result of contacts by such Investor and not as a result of the Registration
Statement, the identity of which shall be reasonably acceptable to the Company.

         8.4      Entire Agreement; Amendment. This Agreement and the other
documents delivered pursuant hereto constitute the full and entire understanding

                  relative rights, preferences and limitations applicable to
                  each class, and series within a class, of capital stock of the

                  limitations applicable to each series (and the authority of
                  the Corporation's board of directors to determine variations
                  for future series).

         The Company shall place legends on each certificate evidencing

applicable state securities laws.

         8.11     Enforcement.

                  8.11.1   Remedies at Law or in Equity. If the Company shall
default in any of its obligations under this Agreement or if any representation

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
this Agreement or as of the applicable Closing Date or as of the date it was
made, furnished or delivered, each Investor may proceed to protect and enforce
its rights by suit in equity or action at law, whether for the specific

breach of any such term or in furtherance of the exercise of any power granted
in this Agreement, or to enforce any other legal or equitable right of such
party or to take any one of more of such actions.

                  8.11.2   Remedies Cumulative; Waiver. No remedy referred to
herein or in any exhibit hereto is intended to be exclusive, but each shall be
cumulative and in addition to any other remedy referred to above or otherwise
available to a party at law or in equity. No express or implied waiver by any
party of any default shall be a waiver of any future or subsequent default. The
failure or delay of any party in exercising any rights granted it hereunder
shall not constitute a waiver of any such right and any single or partial
exercise of any particular right by such party shall not exhaust the same or
constitute a waiver of any other right provided herein.

         8.12     Timely Performance. Time is of the essence as to the
performance of the obligations required of the respective parties under this
Agreement.

         8.13     No Joint Venture. Nothing in this Agreement shall be deemed to
constitute the Company and any Investor as partners, agents or joint venturers.

         8.14     Severability. In the event any one or more of the provisions
contained in this Agreement should be held invalid, illegal or unenforceable in
any respect, the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired
thereby. The parties shall endeavor in good faith negotiations to replace the
invalid, illegal or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

obtain and assist each Investor in obtaining promptly all necessary waivers,
consents and approvals from any governmental authority or any other person
(including the approval of the stockholders of the Company, if necessary) for

The period of time provided for any closing of the transactions pursuant to such
rights may, at the option of each Investor, be extended as necessary in order to
obtain any such waivers, consents and approvals.

         "Liquidation" shall have the meaning provided in Section (b) hereof.

         "Series E Preferred Stock" shall mean the 185,000 shares of Series E
Preferred Stock, without par value per share, hereby designated.

         "Original Issue Date" shall mean, with respect to each share of Series
E Preferred Stock, the date on which such share of Series E Preferred Stock is
first issued by the Corporation.

         "Securities Act" shall mean the federal Securities Act of 1933, as
amended.

         The Designations granted to and imposed upon the Series E Preferred
Stock are as follows:

         (a)      Dividend Rights. The holders of Series E Preferred Stock shall
not be entitled to receive dividends; provided, however, that no dividend shall
be paid on or declared and set apart for any share of Common Equity, other than
the Series A Preferred Stock, for any period unless at the same time an equal
dividend for the same dividend period shall be paid on or declared and set apart
for each share of Series E Preferred Stock based on the number of Conversion
Shares into which each share is then convertible. No dividends shall be paid
with respect to the Series E Preferred Stock unless and until dividends have
been declared and paid on the Corporation's Series A Preferred Stock in
accordance with the Series A Preferred Stock Designations of Preferences,
Limitations and Relative Rights. Dividends on shares of capital stock of the
Corporation shall be payable only out of funds legally available therefor.

         (b)      Liquidation Rights. In the event of the liquidation,
dissolution or winding up for any reason, including, without limitation,
bankruptcy, of the Corporation or any of the Corporation's subsidiaries, the
assets of which constitute all or substantially all the assets of the business
of the Corporation and its subsidiaries taken as a whole or such events
specified in the next sentence (each such event referred to as a "Liquidation"),
the holders of the outstanding shares of Series E Preferred Stock shall, at
their election, be entitled to receive in exchange for and in redemption of each
share of their Series E Preferred Stock, and on a parity with the holders of any
capital stock ranking pari passu to (including the Series B, C and D Preferred
Stock), and prior to any capital stock ranking junior to, the Series E Preferred
Stock by reason of their ownership thereof, from any funds or assets legally
available for distribution to shareholders that portion of such funds, proceeds
or assets in an amount equal to a fraction,

                  (1)      the numerator of which is the number of Conversion
         Shares to which the holder of such share of Series E Preferred Stock
         would be entitled by virtue of 


>PAGE>   29

         converting such share; and

                  (2)      the denominator of which is the Common Stock Deemed
         Outstanding immediately prior to such Liquidation;

provided, however, that, notwithstanding the foregoing, the amount payable to
such holder of a share of Series E Preferred Stock in the event of a Liquidation
of the Corporation, as provided above, shall not be less than, and shall be
increased if necessary (with sums payable to holders of shares of any other
capital stock to be reduced ratably per share as necessary) to equal, the
Invested Amount plus declared but unpaid dividends payable with respect to such
Series E Preferred Stock; provided further, however, that no amount shall be
paid with respect to the Series B, C, D or E Preferred Stock until the holders
of the Corporation's Series A Preferred Stock have been paid in full all amounts
owed upon a Liquidation to the holders of Series A Preferred Stock in accordance
with the Series A Preferred Stock Designation of Preferences, Limitations and
Relative Rights. A Liquidation shall also be deemed to have occurred upon (i)
the acquisition of the Corporation by another entity by means of any transaction
or series of related transactions (including, without limitation, any
reorganization, merger or consolidation) that results in the Corporation's
shareholders immediately prior to such transaction not holding (by virtue of
such shares or securities issued solely with respect thereto) at least 50% of
the voting power of the surviving or continuing entity, or (ii) a sale,
conveyance or disposition of all or substantially all of the assets of the
Corporation unless the Corporation's shareholders immediately prior to such
transaction will, as a result of such sale, conveyance or disposition hold (by
virtue of securities issued as consideration for such sale, conveyance or
disposition) at least 50% of the voting power of the purchasing entity, or (iii)
the effectuation by the Corporation or its stockholders of a transaction or
series of related transactions that results in the Corporation's shareholders
immediately prior to such transaction not holding (by virtue of such shares or
securities issued solely with respect thereto) at least 50% of the voting power
of the Corporation.

         To the extent necessary, the Corporation shall cause such actions to be
taken by any of its subsidiaries so as to enable the proceeds of a Liquidation
to be distributed to the holders of shares of Series E Preferred Stock in
accordance with this Section (b). All the preferential amounts to be paid to the
holders of Series E Preferred Stock under this Section (b) shall be paid or set
apart for payment before the payment or setting apart for payment of any amount
for, or the distribution of any assets of the Corporation to, the holders of
shares of Any Common Stock or any class or series of stock of the Corporation
ranking junior to Series E Preferred Stock in connection with a Liquidation as
to which this Section (b) applies. If the assets or surplus funds to be
distributed to the holders of Series E Preferred Stock are insufficient to
permit the payment to such holders of the full amounts payable to such holders,
the assets and surplus funds legally available for distribution shall be
distributed ratably among the holders of Series E Preferred Stock in proportion
to the full amount each such holder is otherwise entitled to receive.

         (c)      Voting Rights. Except as provided by the Georgia Business
Corporation Code or as otherwise expressly provided herein, the Series E
Preferred Stock shall be non-voting; provided, however, that, with respect to
special class voting arrangements, each holder of a 


>PAGE>   30

share of Series E Preferred Stock shall be entitled to the number of votes equal
to the number of Conversion Shares into which such share of Series E Preferred
Stock would be convertible under the circumstances described in Section (d)
hereof on the record date for the vote or consent of shareholders.

         (d)      Conversion. The holders of Series E Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                  (1)      Conversion Rate.

                           (A)      For purposes of this Section (d), the shares
                  of Series E Preferred Stock shall be convertible, at the times
                  and under the conditions described in this Section (d)
                  hereafter, at the rate (the "Conversion Rate") of one share of
                  Series E Preferred Stock to the number of shares of Common
                  Stock that equals the quotient obtained by dividing the
                  Invested Amount by the Conversion Price (defined hereinafter).
                  Thus, the number of shares of Common Stock to which a holder
                  of Series E Preferred Stock shall be entitled upon any
                  conversion provided for in this Section (d) shall be the
                  product obtained by multiplying the Conversion Rate by the
                  number of shares of Series E Preferred Stock being converted.
                  Such conversion shall be deemed to have been made immediately
                  prior to the close of business on the date of the surrender of
                  the shares of Series E Preferred Stock to be converted in
                  accordance with the procedures described in Subsection (d)(4)
                  below. The "Conversion Price" shall be equal to $54.17, except
                  as otherwise adjusted as provided hereafter in this Section
                  (d). The initial Conversion Rate shall be one share of Series
                  E Preferred Stock for 10 shares of Common Stock.

                           (B)      No fractional shares of Common Stock shall
                  be issued upon conversion of Series E Preferred Stock, and to
                  the extent that the aggregate of all shares of Series E
                  Preferred Stock surrendered at any one time by a single holder
                  thereof would result in the issuance of a fractional share of
                  Common Stock, such fractional share shall be redeemed in cash
                  at the then effective Conversion Price per share, payable as
                  promptly as possible when funds are legally available
                  therefor.

                  (2)      Optional. Subject to Subsection (d)(3) below, each
         share of Series E Preferred Stock shall be convertible, at the option
         of the holder thereof, at any time after the Effective Date (as defined
         in Subsection (d)(9) below) in whole or in part, at the office of the
         Corporation or any transfer agent for the Series E Preferred Stock,
         into Common Stock at the then effective Conversion Rate.

                  (3)      Automatic.

                           (A)      Should the holders of at least a majority of
                  the then outstanding shares of Series E Preferred Stock so
                  elect at any time after the Effective Date by delivery of
                  written notice or notices to the Corporation, each and every


>PAGE>   31

                  outstanding share of Series E Preferred Stock held by all
                  holders of Series E Preferred Stock (whether or not so
                  electing) shall automatically be converted into Common Stock
                  at the then effective Conversion Rate. Such conversion shall
                  be deemed to have been made immediately prior to the close of
                  business on the date of receipt of the last written notice
                  described above necessary to effect such request by a majority
                  of holders. Such conversion shall be automatic, without need
                  for any further action by the holders of shares of Series E
                  Preferred Stock and regardless of whether the certificates
                  representing such shares are surrendered to the Corporation or
                  its transfer agent; provided, however, that the Corporation
                  shall not be obligated to issue certificates evidencing the
                  shares of Common Stock issuable upon such conversion unless
                  certificates evidencing such shares of Series E Preferred
                  Stock so converted are surrendered, or a notice that such
                  certificates have been lost, stolen or destroyed shall have
                  been given, to the Corporation in accordance with the
                  procedures described in Subsection (d)(4) below. Upon the
                  conversion of Series E Preferred Stock pursuant to this
                  Subsection (d)(3)(A), the Corporation shall promptly send
                  written notice thereof, by registered or certified mail,
                  return receipt requested and postage prepaid, by hand delivery
                  or by overnight delivery, to each holder of record of Series E
                  Preferred Stock at his, her or its address then shown on the
                  records of the Corporation, which notice shall state that
                  certificates evidencing shares of Series E Preferred Stock
                  must be surrendered at the office of the Corporation (or of
                  its transfer agent for the Common Stock, if applicable) in the
                  manner described in Subsection (d)(4) below.

                           (B)      The Corporation shall notify each holder of
                  Series E Preferred Stock at least ninety (90) days prior to
                  the anticipated effective date of a registration statement
                  filed by the Corporation under the Securities Act covering an
                  Initial Public Offering; provided that, in the event the
                  Corporation contemplates that such registration statement will
                  become effective at any time during the ninety (90)-day period
                  following the Original Issue Date, the Corporation shall
                  provide such notice to each holder of Series E Preferred Stock
                  at least ten (10) days prior to such effective date. Upon the
                  closing of, but effective immediately prior to, the first sale
                  in an Initial Public Offering, each and every share of
                  outstanding Series E Preferred Stock held by all holders of
                  Series E Preferred Stock shall automatically be converted into
                  Common Stock at the then effective Conversion Rate. Such
                  conversion shall be automatic, without need for any further
                  action by the holders of shares of Series E Preferred Stock
                  and regardless of whether the certificates representing such
                  shares are surrendered to the Corporation or its transfer
                  agent; provided, however, that the Corporation shall not be
                  obligated to issue certificates evidencing the shares of
                  Common Stock issuable upon such conversion unless certificates
                  evidencing such shares of Series E Preferred Stock so
                  converted are surrendered to the Corporation or the holder of
                  record of such shares notifies the Corporation that such
                  certificates have been lost, stolen or destroyed and executes
                  an agreement to indemnify the Corporation from any loss
                  incurred by it in connection with 


>PAGE>   32

                  such certificates, in each case in accordance with the
                  procedures described in Subsection (d)(4) below. Upon the
                  conversion of Series E Preferred Stock pursuant to this
                  Subsection (d)(3)(B), the Corporation shall promptly send
                  written notice thereof, by registered or certified mail,
                  return receipt requested and postage prepaid, by hand delivery
                  or by overnight delivery, to each holder of record of Series E
                  Preferred Stock at his, her or its address then shown on the
                  records of the Corporation, which notice shall state that
                  certificates evidencing shares of Series E Preferred Stock
                  must be surrendered at the office of the Corporation (or of
                  its transfer agent for the Common Stock, if applicable) in the
                  manner described in Subsection (d)(4) below.

                  (4)      Mechanics of Conversion. Before any holder of Series
         E Preferred Stock shall be entitled to receive certificates
         representing the shares of Common Stock into which shares of Series E
         Preferred Stock are converted in accordance with Subsections (d)(2) or
         (d)(3) above, such holder shall surrender the certificate or
         certificates for such shares of Series E Preferred Stock, duly
         endorsed, at the office of the Corporation or of any transfer agent for
         the Series E Preferred Stock, and shall give written notice to the
         Corporation at such office of the name or names in which such holder
         wishes the certificate or certificates for shares of Common Stock to be
         issued, if different from the name shown on the books and records of
         the Corporation (the "Conversion Notice"); provided, that in lieu of
         delivery of the certificates representing shares of Series E Preferred
         Stock, a holder may notify the Corporation that such certificates have
         been lost, stolen or destroyed and execute an agreement satisfactory to
         the Corporation to indemnify the Corporation from any loss incurred by
         it in connection with such certificates. The Conversion Notice shall
         also contain such representations as may reasonably be required by the
         Corporation to the effect that the shares to be received upon
         conversion are not being acquired and will not be transferred in any
         way that might violate the then applicable securities laws. The
         Corporation shall, as soon as practicable thereafter and in no event
         later than thirty (30) days after the delivery of said certificates,
         issue and deliver at such office to such holder of Series E Preferred
         Stock, or to the nominee or nominees of such holder as provided in the
         Conversion Notice, a certificate or certificates for the number of
         shares of Common Stock to which such holder shall be entitled as
         aforesaid. The person or persons entitled to receive the shares of
         Common Stock issuable upon a conversion pursuant to Subsections (d)(2)
         or (d)(3) above shall be treated for all purposes as the record holder
         or holders of such shares of Common Stock as of the effective date of
         conversion specified in such section. All certificates issued upon the
         exercise or occurrence of the conversion shall contain a legend
         governing restrictions upon such shares imposed by law or agreement of
         the holder or his, her or its predecessors.

                  (5)      Adjustment for Subdivisions or Combinations of Common
         Stock. In the event the Corporation at any time, or from time to time,
         after the Original Issue Date effects a subdivision or combination of
         Any Common Stock then outstanding into a greater or lesser number of
         shares without a proportionate and corresponding subdivision or
         combination of the outstanding Series E Preferred Stock, then and in
         each such event the Conversion Price shall be decreased or increased
         proportionately.


>PAGE>   33

                  (6)      Adjustments for Dividends, Distributions and Other
         Common Stock Equivalents. In the event that the Corporation at any
         time, or from time to time, after the Original Issue Date shall make or
         issue, or fix a record date to determine the holders of Any Common
         Stock or other Common Equity entitled to receive, a dividend or other
         distribution payable in additional shares of Any Common Stock or Common
         Stock Equivalents without payment of any consideration by such holder
         of such Common Stock Equivalents or the additional shares of Any Common
         Stock, and without a proportionate and corresponding dividend or other
         distribution to holders of Series E Preferred Stock, then and in each
         such event the maximum number of shares (as set forth in the instrument
         relating thereto without regard to any provisions contained therein for
         subsequent adjustment of such number) of the type of Any Common Stock
         issuable in payment of such dividend or distribution or upon conversion
         or exercise of such Common Stock Equivalents shall be deemed, for
         purposes of this Subsection (d)(6), to be issued and outstanding as of
         the time of such issuance or, in the event such a record date shall
         have been fixed, as of the close of business on such record date. In
         each such event the Conversion Price shall be decreased as of the time
         of such issuance or, in the event such a record date shall have been
         fixed, as of the close of business on such record date, by multiplying
         the Conversion Price by a fraction,

                           (A)      the numerator of which shall be the Common
                  Stock Deemed Outstanding immediately prior to the time of such
                  issuance or the close of business on such record date; and

                           (B)      the denominator of which shall be the total
                  number of shares of Common Stock Deemed Outstanding (not
                  including any shares described in clause (ii) immediately
                  below) immediately prior to the time of such issuance or the
                  close of business on such record date, plus (ii) the number of
                  shares of Any Common Stock issuable in payment of such
                  dividend or distribution or upon conversion or exercise of
                  such Common Stock Equivalents;

provided, however, that (i) if such record date shall have been fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the Conversion Price shall be recomputed accordingly as of the
close of business on such record date and thereafter the Conversion Price shall
be adjusted pursuant to this Subsection (d)(6) as of the time of actual payment
of such dividend or distribution; or (ii) if such Common Stock Equivalents
provide, with the passage of time or otherwise, for any decrease in the number
of shares of Any Common Stock issuable upon conversion or exercise thereof (or
upon the occurrence of a record date with respect thereto), the Conversion Price
computed upon the original issue thereof (or upon the occurrence of a record
date with respect thereto), and any subsequent adjustments based thereon, shall,
upon any such decrease becoming effective, be recomputed to reflect such
decrease insofar as it affects the rights of conversion or exercise of the
Common Stock Equivalents then outstanding; or (iii) upon the expiration of any
rights of conversion or exercise under any unexercised Common Stock Equivalents,
the Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with  


>PAGE>   34
respect thereto), and any subsequent adjustments based thereon, shall,
upon such expiration, be recomputed as if the only additional shares of Any
Common Stock issued were the shares of such stock, if any, actually issued upon
the conversion or exercise of such Common Stock Equivalents; or (iv) in the
event of issuance of Common Stock Equivalents that expire by their terms not
more than sixty (60) days after the date of issuance thereof, no adjustments of
the Conversion Price shall be made until the expiration or exercise of all such
Common Stock Equivalents, whereupon the adjustment otherwise required by this
Subsection (d)(6) shall be made in the manner provided herein.

                  (7)      Adjustment of Conversion Rate for Diluting Issues.
         Except as otherwise provided in this Subsection (d)(7), in the event,
         and each time as, the Corporation sells or issues shares of Any Common
         Stock or Common Stock Equivalents following the Original Issue Date, at
         a per share consideration (as defined below) less than the Conversion
         Price then in effect, then the Conversion Price shall be adjusted as
         provided in this Subsection (d)(7). For purposes of the foregoing, the
         per share consideration with respect to the sale or issuance of a share
         of Any Common Stock shall be the price per share received by the
         Corporation, prior to the payment of any expenses, commissions,
         discounts and other applicable costs. With respect to the sale or
         issuance of Common Stock Equivalents that are convertible or
         exercisable into or exchangeable for Any Common Stock without further
         consideration, the per share consideration shall be determined by
         dividing the maximum number of shares (as set forth in the instrument
         relating thereto without regard to any provisions contained therein for
         subsequent adjustment of such number) of Any Common Stock issuable,
         directly or indirectly with respect to such Common Stock Equivalents
         into the aggregate consideration received by the Corporation upon the
         sale or issuance of such Common Stock Equivalents. With respect to the
         issuance of all other Common Stock Equivalents, the per share
         consideration shall be determined by dividing the maximum number of
         shares (as set forth in the instrument relating thereto without regard
         to any provisions contained therein for subsequent adjustment of such
         number) of Any Common Stock issuable with respect to such Common Stock
         Equivalents into the aggregate consideration received by the
         Corporation upon the sale or issuance of such Common Stock Equivalents
         plus the total consideration receivable by the Corporation upon
         conversion or exercise of such Common Stock Equivalents. The issuance
         of shares of Any Common Stock or Common Stock Equivalents for no
         consideration shall be deemed to be an issuance of shares of Any Common
         Stock at a per share consideration of $.01. In connection with the sale
         or issuance of Common Stock and/or Common Stock Equivalents for
         non-cash consideration, the amount of consideration shall be determined
         by the Board of Directors in good faith.

                  As used herein, "Additional Shares of Common Stock" shall
         mean, with respect to such adjustments to be made to the Conversion
         Price, either shares of Any Common Stock issued subsequent to the
         Original Issue Date, or, with respect to the issuance of Common Stock
         Equivalents, the maximum number of shares (as set forth in the
         instrument relating thereto without regard to any provisions contained
         therein for subsequent adjustment of such number) of Any Common Stock
         issuable in exchange for, upon conversion of, or upon exercise of such
         Common Stock Equivalents.

                           (A)      Upon the issuance or sale by the Corporation
                  of Additional Shares of Common Stock to the public pursuant to
                  an effective registration statement under the Securities Act
                  of 1933, as amended (the "IPO Registration Statement"), either
                  at a price per share to the public (the "IPO Price") less than
                  111% of the Conversion Price then in effect or where the
                  midpoint of the price range set forth on the cover page of the
                  prospectus forming a part of the IPO Registration Statement
                  when such prospectus is first filed with the Securities and
                  Exchange Commission (the "Filing Midpoint") is less than the
                  Conversion Price then in effect, the Conversion Price shall be
                  reduced to the lower of (i) 90% of the Conversion Price then
                  in effect or (ii) the Conversion Price then in effect less 50%
                  of the difference between the Conversion Price then in effect
                  and the lesser of (A) 90% of the IPO Price or (B) the Filing
                  Midpoint.

                           (B)      Upon each issuance or sale by the
                  Corporation of Any Common Stock for a per share consideration
                  less than the Conversion Price as in effect on the date of
                  such issuance, the Conversion Price as in effect on such date
                  shall be adjusted by multiplying it by a fraction:

                                    (i)      the numerator of which shall be the
                           total number of shares of Common Stock Deemed
                           Outstanding immediately prior to the issuance or sale
                           of such Additional Shares of Common Stock plus the
                           number of shares of Any Common Stock that the
                           aggregate net consideration received by the
                           Corporation for the total number of such Additional
                           Shares of Common Stock so issued or sold would
                           purchase at the Conversion Price then in effect; and

                                    (ii)     the denominator of which shall be
                           the total number of shares of Common Stock Deemed
                           Outstanding immediately prior to the issuance or sale
                           of such Additional Shares of Common plus the number
                           of shares of Any Common Stock so issued.

                           (C)      Upon each issuance or sale by the
                  Corporation of Common Stock Equivalents that are exchangeable
                  without further consideration into Common Stock, for a per
                  share consideration less than the Conversion Price as in
                  effect on the date of such issuance, the Conversion Price
                  shall be adjusted as provided in paragraph (B) of this
                  Subsection (d)(7) on the basis that the Additional Shares of
                  Common Stock are to be treated as having been issued on the
                  date of issuance or sale of the Common Stock Equivalents, and
                  the aggregate consideration received by the Corporation for
                  such Common Stock Equivalents shall be deemed to have been
                  received for such Additional Shares of Common Stock.

                           (D)      Upon each issuance or sale by the
                  Corporation of Common Stock Equivalents other than those
                  described in paragraph (C) of this Subsection (d)(7) for a per
                  share consideration less than the Conversion Price as in
                  effect on the date of such issuance, the Conversion Price
                  shall be adjusted as provided in 
>PAGE>   36
                  paragraph (B) of this Subsection (d)(7) on the basis that the
                  Additional Shares of Common Stock are to be treated as having
                  been issued on the date of issuance or sale of such Common
                  Stock Equivalents, and the aggregate consideration received
                  and receivable by the Corporation upon the sale and issuance
                  and on conversion or exercise of such Common Stock Equivalents
                  shall be deemed to have been received for such Additional
                  Shares of Common Stock.

                           (E)      Once any Additional Shares of Common Stock
                  have been treated as having been issued or sold for the
                  purpose of this Subsection (d)(7), they shall be treated as
                  issued and outstanding shares of Any Common Stock whenever any
                  subsequent calculations must be made pursuant hereto; provided
                  that on the expiration of any options, warrants or rights to
                  purchase Additional Shares of Common Stock, the termination of
                  any rights to convert or exchange for Additional Shares of
                  Common Stock, or the expiration of any options or rights
                  related to such convertible or exchangeable securities on
                  account of which an adjustment in the Conversion Price has
                  been made previously pursuant to this Subsection (d)(7), such
                  Conversion Price shall forthwith be readjusted to the
                  Conversion Price as would have obtained had the adjustment
                  made upon the issuance of such options, warrants, rights,
                  securities or options or rights related to such securities
                  been made upon the basis of the issuance of only the number of
                  shares of Any Common Stock actually issued upon the exercise
                  of such options, warrants or rights, upon the conversion or
                  exchange of such securities or upon the exercise of the
                  options or rights related to such securities.

                           (F)      Upon each issuance or sale by the
                  Corporation of Additional Shares of Common Stock in connection
                  with any merger, consolidation or other reorganization in
                  which the Corporation is the surviving corporation which
                  results in an adjustment pursuant to this Subsection (d)(7),
                  the amount of consideration received therefrom shall be deemed
                  to be the fair market value, as determined in good faith by
                  the Board of Directors, of such portion of the assets and
                  business of the non-surviving person or persons as the Board
                  of Directors determines in good faith to be attributable to
                  such Additional Shares of Common Stock and evidence of such
                  determination shall be filed with the minutes of the
                  Corporation.

                           (G)      The foregoing notwithstanding, no adjustment
                  of the Conversion Price shall be made pursuant to this
                  Subsection (d)(7) as a result of the issuance of:

                                    (i)      any shares of Common Stock upon the
                           conversion of shares of Series E Preferred Stock;

                                    (ii)     except as specifically contemplated
                           by Subsection (d)(7)(A), securities of the
                           Corporation offered to the public pursuant to an
                           effective registration statement under the Securities
                           Act;


>PAGE>   37

                                    (iii)    the Corporation's securities
                           pursuant to the acquisition by the Corporation of any
                           product, technology, know-how or another corporation
                           by merger, purchase of all or substantially all the
                           securities or assets, or any other reorganization
                           whereby the Corporation owns over fifty percent (50%)
                           of the voting power of such corporation;

                                    (iv)     any shares of Common Stock or
                           Common Stock Equivalents pursuant to which the
                           Conversion Price is adjusted under Subsection (5),
                           (6), (8) or (9) of this Section (d) (including,
                           without limitation, any shares of Common Stock or
                           Common Stock Equivalents pursuant to which a
                           proportionate and corresponding dividend is made to
                           the holders of the Series E Preferred Stock as
                           contemplated by Subsections (d)(6) or (8));

                                    (v)      any shares of Any Common Stock
                           issued at any time following the Original Issue Date
                           pursuant to options, warrants or rights granted
                           either before or after the Original Issue Date to
                           purchase shares of such series of Any Common Stock,
                           less the number of any such options, warrants or
                           rights that are repurchased by the Corporation, are
                           canceled or expire, in each case in favor of
                           employees, directors, officers or consultants of the
                           Corporation or any subsidiary thereof pursuant to a
                           stock option plan or agreement approved by the Board
                           of Directors; provided, however, that such stock
                           options thereunder, if granted after the Original
                           Issue Date, are granted at a conversion or exercise
                           price that the 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; or

                                    (vi)     any shares of Any Common Stock
                           issued pursuant to the exchange, conversion or
                           exercise of any Common Stock Equivalents that have
                           previously been incorporated into computations
                           hereunder on the date when such Common Stock
                           Equivalents were issued.

                  (8)      In-Kind Distributions. In the event the Corporation
         shall declare a distribution payable generally to holders of its
         outstanding shares of Common Equity in any securities of other persons,
         evidences of indebtedness issued by the Corporation or other persons or
         assets (excluding cash dividends) then, in each such case for the
         purpose of this subsection (d)(8) the holders of the Series E Preferred
         Stock shall be entitled to a proportionate of any such distribution as
         though they were the holders of the Conversion Shares as of the record
         date fixed for determination of the holders of Common Equity entitled
         to such distribution.

                  (9)      Adjustment of Conversion Shares--Delay Shares. In the
         event the Corporation has not issued or sold any Additional Shares of
         Common Stock to the public pursuant to an effective registration
         statement under the Securities Act of 1933, as amended, on or prior to
         the Effective Date, the Conversion Price then in effect shall 


>PAGE>   38

         be adjusted to 71.72% of the Conversion Price then in effect. As used
         herein, the "Effective Date" shall mean January 15, 2000 plus the
         number of days during the period from and including (i) the date that
         Corporation receives notice from the Securities and Exchange Commission
         that the Corporation should discontinue the disposition of the Common
         Stock contemplated by the Registration Statement of the Corporation on
         Form S-1 (No. 333-71359), as amended, as a result of the issuance of
         the Series E Preferred Stock or the Series F Preferred Stock or the
         transactions contemplated by the Master Agreement dated as of April 10,
         1999 (the "Master Agreement") between the Corporation and Microsoft
         Corporation to and including (ii) the date the Corporation can resume
         such disposition pursuant to such registration statement or another
         registration statement covering the sale of any Additional Common Stock
         to the public. Any adjustment in the Conversion Rate pursuant to this
         subsection (d)(9) shall not result in an adjustment to the Conversion
         Rate pursuant to subsection (d)(7) hereof or subsection (d)(7) of the
         Designations of Preferences, Limitations and Relative Rights of Series
         F Preferred Stock of WebMD, Inc., but the Conversion Rate as adjusted
         pursuant to this subsection (d)(9) shall become the Conversion Rate for
         purposes of any further adjustments under subsection (d)(7) hereof.

                  (10)     De Minimis Adjustments. No adjustment to the
         Conversion Price shall be made if such adjustment would result in a
         change in the Conversion Price of less than $.01. Any adjustment of
         less than $.01 that is not made shall be carried forward and shall be
         made at the time of and together with any subsequent adjustment that,
         on a cumulative basis, amounts to an adjustment of $.01 or more in the
         Conversion Price.

                  (11)     No Impairment. Except as provided in Section (e)
         hereof, the Corporation shall not, by amendment of the Articles of
         Incorporation or the Bylaws or through any reorganization, transfer of
         assets, consolidation, merger, dissolution, issue or sale of securities
         or any other voluntary action, avoid or seek to avoid the observance or
         performance of any of the terms to be observed or performed hereunder
         by the Corporation, but shall at all times in good faith assist in the
         carrying out of all the provisions of this Section (d) and in the
         taking of all such action as may be necessary or appropriate in order
         to protect the Conversion Rights of the holders of the Series E
         Preferred Stock against impairment.

                  (12)     Certificate as to Adjustments. Upon the occurrence of
         each adjustment or readjustment of the Conversion Price pursuant to
         this Section (d), the Corporation at its expense shall promptly compute
         such adjustment or readjustment in accordance with the terms hereof and
         cause independent public accountants selected by the Corporation to
         verify such computation and prepare and furnish to each holder of
         Series E Preferred Stock a certificate setting forth such adjustment or
         readjustment and showing in detail the facts upon which such adjustment
         or readjustment is based. The Corporation shall, upon the written
         request at any time of any holder of Series E Preferred Stock, furnish
         or cause to be furnished to such holder a like certificate setting
         forth (i) such adjustments and readjustments, (ii) the Conversion Price
         and the Conversion Rate at that time in effect, and (iii) the number of
         shares of Common Stock and the amount, if 


>PAGE>   39

         any, of other property that at that time would be received upon the
         conversion of Series E Preferred Stock.

                  (13)     Notices of Record Date. In the event of any taking by
         the Corporation of a record of the holders of any series or class of
         securities other than Series E Preferred Stock for the purpose of
         determining the holders thereof who are entitled to receive any
         dividend or other distribution, any Common Stock Equivalents or any
         right to subscribe for, purchase or otherwise acquire any shares of
         stock of any class or any other securities or property, or to receive
         any other right, the Corporation shall mail to each holder of Series E
         Preferred Stock, at least twenty (20) days prior to the date specified
         therein, a notice specifying the date on which any such record is to be
         taken for the purpose of such dividend, distribution or rights, and the
         amount and character of such dividend, distribution or rights.

                  (14)     Reservation of Stock Issuable Upon Conversion. The
         Corporation shall at all times reserve and keep available out of its
         authorized but unissued shares of Common Stock solely for the purpose
         of effecting the conversion of the shares of the Series E Preferred
         Stock such number of its shares of Common Stock as shall from time to
         time be sufficient to effect the conversion of all outstanding shares
         of the Series E Preferred Stock; and if at any time the number of
         authorized but unissued shares of Common Stock shall be insufficient to
         effect the conversion of all then outstanding shares of the Series E
         Preferred Stock, the Corporation shall take such corporate action as
         may, in the opinion of its counsel, be necessary to increase its
         authorized but unissued shares of Common Stock to such number of shares
         as shall be sufficient for such purpose.

         (e)      Protective Provisions. In addition to any other rights
provided by law, so long as any shares of Series E Preferred Stock are then
outstanding, except where the vote or written consent of the holders of a
greater number of shares is required by law or by another provision of the
Articles of Incorporation, without first obtaining the affirmative vote or
written consent of the holders of a majority of the total number of shares of
Series E Preferred Stock outstanding, voting together as a single class, the
Corporation shall not, and shall cause its subsidiaries not to:

                  (1)      amend or repeal any provision of, or add any
         provision to, the Articles of Incorporation or the Bylaws, or file any
         certificate of designations, preferences, limitations and relative
         rights of any series or class of preferred stock, if such action would
         alter or change the preferences, rights, privileges or powers of, or
         restrictions provided for the benefit of holders of Series E Preferred
         Stock;

                  (2)      create or authorize the creation of any additional
         series or class of shares of stock, or increase the authorized amount
         of any series or class of capital stock, unless the same ranks junior
         or pari passu to the Series E Preferred Stock as to dividends and the
         distribution of assets upon a Liquidation of the Corporation;
         regardless of whether any such creation, authorization or increase
         shall be by means of amendment to the Articles of Incorporation, or by
         merger, consolidation or otherwise;


>PAGE>   40

                  (3)      increase or decrease the authorized number of shares
         of the Series E Preferred Stock;

                  (4)      take any action that would alter or change the

                          DESIGNATIONS OF PREFERENCES,
                       LIMITATIONS, AND RELATIVE RIGHTS OF
                     SERIES F PREFERRED STOCK OF WEBMD, INC.

         The designations of preferences, limitations, and relative rights
granted to and imposed upon the Series F Preferred Stock are identical to the
designations of preferences, limitations, and relative rights of Series E
Preferred Stock of WebMD, Inc., (the "Series E Designations"), except with
respect to certain definitions, Dividend Rights, Liquidation Rights and
Adjustment of Conversion Rate-Delay Shares. Whenever the Series E Designations
refers to "Series E Preferred Stock," this Designation shall refer to the
"Series F Preferred Stock," and the Series E Preferred Stock shall mean, for
purposes of this Designation, the 1,180,000 shares of Series F Preferred Stock,
without par value per share hereby designated. The Dividend Rights, Liquidation
Rights and Adjustment of Conversion Rate-Delay Shares for the Series F Preferred
Stock are as follows:

         (a)      Dividend Rights. The holders of Series F Preferred Stock shall
not be entitled to receive dividends; provided, however, that no dividend shall
be paid on or declared and set apart for any share of Any Common Stock for any
period unless at the same time an equal dividend for the same dividend period
shall be paid on or declared and set apart for each share of Series E Preferred
Stock based on the number of Conversion Shares into which each share is then
convertible. Dividends on shares of capital stock of the Corporation shall be
payable only out of funds legally available therefor.

         (b)      Liquidation Rights. In the event of the liquidation,
dissolution or winding up for any reason, including, without limitation,
bankruptcy, of the Corporation or any of the Corporation's subsidiaries, the
assets of which constitute all or substantially all the assets of the business
of the Corporation and its subsidiaries taken as a whole or such events
specified in the next sentence (each such event referred to as a "Liquidation"),
the holders of the outstanding shares of Series F Preferred Stock shall be
entitled to receive in exchange for and in redemption of each share of their
Series F Preferred Stock from any funds or assets legally available for
distribution to shareholders that portion of such funds, proceeds or assets in
an amount equal to a fraction,

                  (1)      the numerator of which is the number of Conversion
Shares to which the holder of such share of Series F Preferred Stock would be
entitled by virtue of converting such share; and

                  (2)      the denominator of which is the Common Stock Deemed
Outstanding immediately prior to such Liquidation;

provided, however, that no amount shall be paid with respect to the Series F
Preferred Stock until the holders of the Corporation's Series A, B, C, D and E
Preferred Stock have been paid in full all amounts owed upon a Liquidation to
the holders of Series A, B, C, D and E Preferred Stock in accordance with their
respective Designations of Preferences, Limitations and Relative Rights. A
Liquidation shall also be deemed to have occurred upon (i) the



                                       1
>PAGE>   43

acquisition of the Corporation by another entity by means of any transaction or
series of related transactions (including, without limitation, any
reorganization, merger or consolidation) that results in the Corporation's
shareholders immediately prior to such transaction not holding (by virtue of
such shares or securities issued solely with respect thereto) at least 50% of
the voting power of the surviving or continuing entity, or (ii) a sale,
conveyance or disposition of all or substantially all of the assets of the
Corporation unless the Corporation's shareholders immediately prior to such
transaction will, as a result of such sale, conveyance or disposition hold (by
virtue of securities issued as consideration for such sale, conveyance or
disposition) at least 50% of the voting power of the purchasing entity, or (iii)
the effectuation by the Corporation or its stockholders of a transaction or
series of related transactions that results in the Corporation's shareholders
immediately prior to such transaction not holding (by virtue of such shares or
securities issued solely with respect thereto) at least 50% of the voting power
of the Corporation.

         (d)(9) Adjustment of Conversion Rate-Delay Shares. In the event the
Corporation has not issued or sold any Additional Shares of Common Stock to the
public pursuant to an effective registration statement under the Securities Act
of 1933, as amended, on or prior to the Effective Date, the Conversion Price
then in effect shall be adjusted to 86% of the Conversion Price then in effect.
As used herein, the "Effective Date" shall mean January 15, 2000 plus the number
of days during the period from and including (i) the date that Corporation
receives notice from the Securities and Exchange Commission that the Corporation
should discontinue the disposition of the Common Stock contemplated by the
Registration Statement of the Corporation on Form S-1 (No. 333-71359), as
amended, as a result of the issuance of the Series E Preferred Stock or the
Series F Preferred Stock or the transactions contemplated by the Master
Agreement dated as of April 10, 1999 (the "Master Agreement") between the
Corporation and Microsoft Corporation to and including (ii) the date the
Corporation can resume such disposition pursuant to such registration statement
or another registration statement covering the sale of any Additional Common
Stock to the public. Any adjustment in the Conversion Rate pursuant to this
subsection (d)(9) hereof shall not result in an adjustment to the Conversion
Rate pursuant to subsection (d)(7) hereof or subsection (d)(7) of the Series E
Designations, but the Conversion Rate as adjusted pursuant to this subsection
(d)(9) shall become the Conversion Rate for purposes of any further adjustments
under subsection (d)(7) hereof.

who has exercised a demand right to register shares of Common Stock (other than

statement on Form S-3 (or any similar short-form registration statement));

                  (iv)     Within the sixty (60) day period immediately

least ninety (90) consecutive days.

         Subject to the foregoing clauses (i) through (v), 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. The Initiating Holders may, at any time prior to the
effective date of the registration statement relating to such registration,
revoke such request, without liability (except as set forth in Section 6 hereof)
to the Initiating Holders or any other Holders of Registrable Securities
requested to be registered pursuant to Section 2(a) hereof, by providing a
written notice to the Company revoking such request.

         Notwithstanding the above, the Company shall not be obligated to

Section 2 during the period starting with the date ninety (90) days prior to the
Company's good faith estimate of the date of filing of (or in the case of any

Registration to become effective and provided further that the Company gives
notice to all Holders upon commencement of such period. The Holders shall be
entitled to exercise their rights pursuant to Section 4 hereof with respect to
an Intended Registration. An Intended Registration shall not be deemed to be a
demand registration of the Holders pursuant to this Section 2.

         (c)      Underwriting. If the Holders propose an underwritten offering,
the sale of Registrable Securities pursuant to this Section 2 must be made by
means of a firm commitment underwriting through underwriters who are reasonably
acceptable to the Company and the holders of a majority of the Registrable
Securities that are proposed to be distributed through such underwriting. The
right of any Holder to registration pursuant to this Section 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 requested by such Holder (unless mutually otherwise agreed by a majority
in interest of the Holders and such Holder) to the extent provided herein.

         The Company and all Holders proposing to distribute Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting. Notwithstanding any other provision of this Section 2(c), if the
underwriter determines that in its good faith view marketing factors require a
limitation of the number of shares to be underwritten and so advises the
Initiating Holders in writing, then the Initiating Holders shall so advise the
Company and all Holders (except those Holders who have indicated to the Company
their decision not to distribute any of their Registrable Securities through
such underwriting) and the number of Registrable Securities that may be included
in the registration and underwriting shall be allocated first to the Holders on
a pro rata basis according to the number of Registrable Securities requested to
be included by the Holders; second to the Company; and third to other
shareholders of the Company who have requested to sell in the registration. No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. If at
least eighty percent (80%) of the Registrable Securities requested to be
registered by the Initiating Holders are not included in such registration, then
the Initiating Holders may request that the Company effect an additional
registration under the Securities Act of all or part of the Initiating Holders'
Registrable Securities in accordance with the provisions of this Section 2, and
the Company shall effect such additional registration.

         If any Holder 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 Registrable Securities and/or other
securities so withdrawn from such underwriting shall also be withdrawn from such
registration; provided, however, that, if by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used above in determining the
underwriter limitation.



                                       5
>PAGE>   50

         If the underwriter has not limited the number of Registrable Securities
to be underwritten, the Company may include securities for its own account or
the account of others in such registration if the underwriter so agrees and if
the number of Registrable Securities which would otherwise have been included in
such registration and underwriting will not thereby be limited.

         (d)      If the Company shall furnish to the Initiating Holders a
certificate signed by the President of the Company stating that, in the good
faith judgment of the Board of Directors of the Company, it would (because of
the existence of, or in anticipation of, any acquisition, financing activity, or
other transaction involving the Company, or the unavailability for reasons
beyond the Company's control of any required financial statements, disclosure of
information which is in its best interest not to publicly disclose, or any other
event or condition of similar significance to the Company) be seriously
detrimental to the Company and its shareholders for such registration statement
to be filed on or before the date filing would be required and it is therefore
essential to defer the filing of such registration statement, then the Company
may direct that such request for registration be delayed for a period not in
excess of ninety (90) days, such right to delay a request to be exercised by the
Company not more than twice in any twelve (12) month period.

         (e)      Effective Registration Statement. A demand registration
requested pursuant to this Section 2 shall not be deemed to have been effected
unless the registration statement relating thereto (i) has become effective
under the Securities Act and any of the Registrable Securities of the Initiating
Holders included in such registration have actually been sold thereunder, and
(ii) has remained effective for a period of at least ninety (90) days (or such
shorter period in which all Registrable Securities included in such registration
have actually been sold thereunder).

         3. S-3 Registration. In case the Company shall receive from any Holder
or Holders a written request or requests that the Company effect a registration
on Form S-3 and any related qualification or compliance with respect to all or a
part of the Registrable Securities owned by such Holder or Holders, the Company
will:

         (a)      promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

         (b)      as soon as practicable, and in any event within 30 days of the
receipt of such notice, file a registration statement on Form S-3 and effect all
other qualifications and compliances as may be so requested and as would permit
or facilitate the sale, distribution, transfer or hedging (through market
transactions using brokers, in a firm commitment underwriting, in negotiated
transactions or otherwise) of all or such portion of such Holder's or Holders'
Registrable Securities as are specified in such request, together with all or
such portion of the



                                       6
>PAGE>   51

Registrable Securities of any other Holder or Holders joining in such request as
are specified in a written request given within 15 days after receipt of such
written notice from the Company; provided, that the Company shall not be
obligated to effect any such registration, qualification or compliance pursuant
to this Section 3:

                  (i)      if Form S-3 is not available for such offering by the
Holders;

                  (ii)     if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to register Registrable Securities and such other securities (if any) at
an aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $20 million;

                  (iii)    if the Company has, within the twelve (12) month
period preceding the date of such request, already effected three (3)
registrations for the Holders pursuant to this Section 1.3; or

                  (iv)     in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.

         (c)      Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders and shall keep it continuously effective
until such Registrable Securities have been sold pursuant thereto.

         (d)      Notwithstanding the other provisions of this Section 3, the
Company shall have the right to delay the filing of any registration statement
on Form S-3 (an "S-3 Registration") otherwise required to be prepared and filed
by the Company pursuant to this Section 3, or to suspend the use of any S-3
Registration, for a period not in excess of 60 days (a "S-3 Blackout Period") if
the Company, in the good faith judgment of its Board of Directors, determines
(because of the existence of, or in anticipation of, any acquisition, financing
activity, or other transaction involving the Company, or the unavailability for
reasons beyond the Company's control of any required financial statements,
disclosure of information which is in its best interest not to publicly
disclose, or




                                       7
>PAGE>   52

any other event or condition of similar significance to the Company) that the
registration and distribution of the Registrable Securities to be covered by
such S-3 Registration would be seriously detrimental to the Company and its
shareholders, provided that the S-3 Blackout Period shall earlier terminate on
the second business day following the completion or abandonment of the relevant
financing, acquisition or other transaction or upon public disclosure by the
Company or public admission by the Company of such material nonpublic
information or such time as such material nonpublic information shall be
publicly disclosed; and provided, further, that the Company shall furnish to the
Holders a certificate of an executive officer of the Company to the effect that
an event permitting a S-3 Blackout Period has occurred (and no other reason need
be given). The Company will promptly give the Holders written notice of such
determination and an approximation of the period of the anticipated delay;
provided, however, that the aggregate number of days included in all S-3
Blackout Periods during any consecutive 12 months shall not exceed 180 days.
Each Holder agrees to cease all disposition efforts under such S-3 Registration
with respect to Registrable Securities held by such Holder immediately upon
receipt of notice of the beginning of any S-3 Blackout Period. The Company shall
provide written notice to the Holders of the end of each S-3 Blackout Period.

         4.       Piggyback Registration.

         (a)      If the Company shall determine to register for sale for cash
any of its Common Stock, for its own account or for the account of others (other
than the Holders), other than a registration relating solely to employee benefit
plans or securities issued or issuable to employees, consultants (to the extent
the securities owned or to be owned by such consultants could be registered on
Form S-8) or any of their Family Members (including a registration on Form S-8),
or a registration relating solely to a Commission Rule 145 transaction, a
registration on Form S-4 in connection with a merger, acquisition, divestiture,
reorganization or similar event, the Company promptly will give to each Holder
written notice thereof and shall use its reasonable best efforts to 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 within ten (10) days
after receipt of such written notice from the Company, by any Holder or Holders.
However, the Company may, without the consent of the Holders, withdraw such
registration statement prior to its becoming effective if the Company has
abandoned its proposal to register the securities proposed to be registered
thereby.

         (b)      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



                                       8
>PAGE>   53

as a part of the written notice given pursuant to Section 4(a). In such event
the right of any Holder to registration pursuant to Section 4(a) 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 any other
shareholders of the Company distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 4(b), if the underwriter or
the Company determines that marketing factors require a limitation of the number
of shares to be underwritten, the underwriter may exclude some or all
Registrable Securities from such registration and underwriting. The Company
shall so advise all Holders (except those Holders who have indicated to the
Company their decision not to distribute any of their Registrable Securities
through such underwriting), and the number of shares of Registrable Securities
that may be included in the registration and underwriting, if any, shall be
allocated among such Holders as follows:

                  (i)      In the event of a piggyback registration pursuant to
Section 4(a) that is initiated by the Company, then the number of shares that
may be included in the registration and underwriting shall be allocated first to
the Company and then to all selling shareholders, including the Holders, who
have requested to sell in the registration on a pro rata basis according to the
number of shares requested to be included; provided, however, that no allocation
pursuant to this Section 4(b) shall have the effect of reducing the Shares sold
by Holders to less than 20% of the proposed offering; and

                  (ii)     In the event of a piggyback registration pursuant to
Section 4(a) that is initiated by the exercise of demand registration rights by
a shareholder or shareholders of the Company (other than the Holders), then the
number of shares that may be included in the registration and underwriting shall
be allocated first to such selling shareholders who exercised such demand and
then to all selling shareholders, including the Holders, who have requested to
sell in the registration, on a pro rata basis according to the number of shares
requested to be included;

provided, however, that in no event shall the total number of shares included in
the offering by any of HBO & Company of Georgia ("HBOC") and Premiere
Technologies, Inc. ("Premiere") 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
securities held by HBOC and Premiere requested to be included in such offering
are included in such offering or unless HBOC and Premiere waive such limitation
or choose not to sell any shares in such registration, and the number of shares
that Holders would otherwise be entitled to include in such registration may be
reduced to give effect to this requirement.

         (c)      No Registrable Securities excluded from the underwriting by
reason of the underwriter's marketing limitation shall be included in such
registration. If any Holder disapproves of the terms of any such underwriting,
such person may elect to withdraw therefrom by written notice to the Company and
the underwriter. The Registrable Securities



                                       9
>PAGE>   54

and/or other securities so withdrawn from such underwriting shall also be
withdrawn from such registration; provided, however, that, if by the withdrawal
of such Registrable Securities a greater number of Registrable Securities held
by other Holders may be included in such registration (up to the maximum of any
limitation imposed by the underwriters), then the Company shall offer to all
Holders who have included Registrable Securities in the registration the right
to include additional Registrable Securities pursuant to the terms and
limitations set forth herein in the same proportion used above in determining
the underwriter limitation.

         5.       Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to Section 2, 3 or
4 hereof, the Company will keep each Holder advised in writing as to the
initiation of each registration, qualification and compliance and as to the
completion thereof. At its expense, the Company will use its reasonable best
efforts to:

         (a)      prepare and file with the Commission within ninety (90) days
(or in the case of any registration on Form S-3, thirty (30) days) after receipt
of a request for registration with respect to such Registrable Securities, a
registration statement on any form for which the Company then qualifies or which
counsel for the Company shall deem appropriate, subject to Section 2 hereof, and
which form shall be available for the sale of the Registrable Securities in
accordance with the intended method(s) of distribution thereof, and use its best
efforts to cause such registration statement to become and remain effective;
provided that before filing with the Commission a registration statement or
prospectus or any amendments or supplements thereto, including documents
incorporated by reference after the initial filing of any registration
statement, the Company shall (i) furnish to the underwriters, if any, and to one
(1) counsel selected by the Holders of a majority of the Registrable Securities
covered by such registration statement copies of all such documents proposed to
be filed, which documents shall be subject to the review of the underwriters and
such counsel, and (ii) notify each Holder of Registrable Securities covered by
such registration statement of any stop order issued or threatened by the
Commission and take all reasonable actions required to prevent the entry of such
stop order or to remove it if entered;

         (b)      prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
a period of not less than ninety (90) days or such shorter period which shall
terminate when all Registrable Securities covered by such registration statement
have been sold (but not before the expiration of the 90-day period referred to
in Section 4(3) of the Securities Act and Rule 174, or any successor thereto,
thereunder, if applicable), and comply with the provisions of the Securities Act
with respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended method(s) of
disposition by the sellers thereof set forth in such registration statement;

         (c)      furnish, without charge, to each Holder and each underwriter,
if any, of Registrable Securities covered by such registration statement one (1)
signed copy of such registration statement, each amendment and supplement
thereto (including one (1) conformed



                                       10
>PAGE>   55

copy to each Holder and one (1) signed copy to each managing underwriter and in
each case including all exhibits thereto), and such number of copies of the
prospectus included in such registration statement (including each preliminary
prospectus and any other prospectus filed under Rule 424 under the Securities
Act) as such Holders may request, in conformity with the requirements of the
Securities Act, and such other documents as such Holder may reasonably request
in order to facilitate the disposition of the Registrable Securities owned by
such Holder, but only while the Company shall be required under the provisions
hereof to cause the registration statement to remain effective;

         (d)      use its best efforts to register or qualify such Registrable
Securities under such other applicable securities or blue sky laws of such
jurisdictions as any Holder, and underwriter, if any, of Registrable Securities
covered by such registration statement reasonably requests as may be necessary
for the marketability of the Registrable Securities (such request to be made by
the time the applicable registration statement is deemed effective by the
Commission) and do any and all other acts and things which may be reasonably
necessary or advisable to enable such Holder and each underwriter, if any, to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by such Holder; provided that the Company shall not be required to (i)
qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph (d), (ii) subject itself
to taxation in any such jurisdiction, or (iii) consent to general service of
process in any such jurisdiction;

         (e)      use its best efforts to cause the Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company to enable the Holder or Holders thereof
to consummate the disposition of such Registrable Securities;

         (f)      immediately notify the managing underwriter, if any, and each
Holder of such Registrable Securities at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event which comes to the Company's attention if as a result of such event
the prospectus included in such registration statement contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading and
the Company shall promptly prepare and furnish to such Holder a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus shall not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading,
unless suspension of the use of such prospectus otherwise is authorized herein
or in the event of a S-3 Blackout Period, in which case no supplement or
amendment need be furnished;

         (g)      use its best efforts to cause all such Registrable Securities
covered by the registration statement to be listed on the Nasdaq Stock Market or
the national securities exchange on which similar securities issued by the
Company are then listed, and enter into such customary agreements including a
listing application and indemnification agreement in



                                       11
>PAGE>   56

customary form (provided that the applicable listing requirements are
satisfied), and to provide a transfer agent and registrar for such Registrable
Securities covered by such registration statement no later than the effective
date of such registration statement;

         (h)      enter into such customary agreements (including an
underwriting agreement in customary form) and take all such other actions as the
Initiating Holders or the underwriters retained by such Holders, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities, including customary indemnification;

         (i)      make available for inspection during normal business hours by
any Holder of Registrable Securities covered by such registration statement, any
underwriter participating in any disposition pursuant to such registration
statement, and any attorney, accountant or other agent retained by any such
Holder or underwriter (collectively, the "Inspectors"), all financial and other
records, pertinent corporate documents and properties of the Company and its
subsidiaries (collectively, "Records"), if any, as shall be reasonably necessary
to enable them to exercise their due diligence responsibility, and cause the
Company's and its subsidiaries' officers, directors and employees to supply all
information and respond to all inquiries reasonably requested by any such
Inspector in connection with such registration statement. Notwithstanding the
foregoing, the Company shall have no obligation to disclose any Records to the
Inspectors in the event the Company determines that such disclosure is
reasonably likely to have an adverse effect on the Company's ability to assert
the existence of an attorney-client privilege with respect thereto;

         (j)      in the event that any contemplated public offering is
underwritten, use its best efforts to obtain a "comfort" letter from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by "comfort" letters as the Holders of a
majority (by number of shares) of the Registrable Securities being sold
reasonably request, and provided that such request is reasonable in the
underwriter's point of view;

         (k)      use its best efforts to obtain an obtain an opinion of counsel
from the Company's counsel in customary form and covering such matters of the
type customarily covered in opinions of counsel in connection with such
transactions;

         (l)      comply, and continue to comply during the period that such
registration statement is effective under the Securities Act, in all material
respects with the Securities Act and the Securities Exchange Act of 1934 and
with all applicable rules and regulations of the Commission with respect to the
disposition of all securities covered by such registration statement, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve (12) months, but not
more than eighteen (18) months, beginning with the first full calendar month
after the effective date of such registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act,
and not file any amendment or supplement to such registration statement or
prospectus to which Holder shall have reasonably objected on the grounds that
such amendment or supplement does not comply in all material respects with the
requirements




                                       12
>PAGE>   57

of the Securities Act, having been furnished with a copy thereof at least five
(5) business days prior to the filing thereof; and

         (m)      in the event the offering is underwritten, develop a
presentation reasonably acceptable to the underwriters to facilitate the
offering and to make its chief executive officer and chief financial officer
available for participation in such meetings and presentations (e.g., road show
for the offering) at such locations (including Europe) as the underwriter
reasonably requests.

Each Holder of Registrable Securities agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
5(f) hereof, such Holder shall discontinue disposition of Registrable Securities
pursuant to the registration statement covering such Registrable Securities
until such Holder's receipt of the copies of the supplemented or amended
prospectus contemplated by Section 5(f) hereof, and, if so directed by the
Company, such Holder shall deliver to the Company (at the Company's expense) all
copies (including, without limitation, any and all drafts), other than permanent
file copies, then in such Holder's possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice. In the
event the Company shall give any such notice, the period mentioned in Section
5(b) hereof shall be extended by the greater of (i) ten (10) business days or
(ii) the number of days during the period from and including the date of the
giving of such notice pursuant to Section 5(f) hereof to and including the date
when each Holder of Registrable Securities covered by such registration
statement shall have received the copies of the supplemented or amended
prospectus contemplated by Section 5(f) hereof.

         6.       Rule 144. Notwithstanding anything to the contrary contained
herein, no Holder shall have rights to a registration under Section 2, 3 or 4
hereof after the time that such Holder could sell, within ninety (90) days, all
of its Registrable Securities pursuant to Rule 144(e) promulgated under the
Securities Act or any successor rule thereto; provided that the Company hereby
agrees to take the following actions to ensure the availability of Rule 144 to
each such Holder (or such similar actions as shall be required under any
successor rule thereto):

         (a)      make and keep public information available as those terms are
understood and defined in Rule 144;

         (b)      use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

         (c)      so long as any Holder owns any Registrable Securities, furnish
to a Holder upon request, a written statement by the Company as to its
compliance with the reporting requirements of Rule 144 (at any time from and
after ninety (90) days following the effective date of the registration
statement relating to an Initial Public Offering), and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting




                                       13
>PAGE>   58

requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents so filed as the Holder may
reasonably request.

         7.       Registration Expenses. The Company shall pay all expenses in
connection with any registration, including, without limitation, all
registration, filing and NASD fees, printing expenses, all fees and expenses of
complying with securities or blue sky laws, the fees and disbursements of one
counsel for the Holders and the fees and disbursements of counsel for the
Company and of its independent accountants; provided that, in any registration,
each party shall pay for its own underwriting discounts and commissions and
transfer taxes. The Company shall not, however, be required to pay for expenses
of any registration proceeding begun pursuant to Section 2, 3 or 4 hereof, the
request of which has been subsequently withdrawn by the Initiating Holders
(unless the withdrawal is based upon material adverse information concerning the
Company of which the Initiating Holders were unaware at the time of such
request), in which case such expenses shall be borne by the Holders whose
securities were to be included in the registration in proportion to the number
of shares for which such registration was requested.

         8.       Assignment of Rights. Any Holder may assign its rights under
this Agreement to any party acquiring 2,400,000 shares or more of Registrable
Securities; provided, however, that a Holder may assign its rights under this
Agreement without such restrictions to a transferee or assignee that controls,
is controlled by or is under common control with such Holder.

         9.       Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing.

         10.      "Market Stand-off" Agreement. Each Holder agrees not to sell
or otherwise transfer or dispose of any Common Stock (or other securities) of
the Company held by it during the 180 day period following the effective date of
the Initial Public Offering if so requested by the Company and underwriters of
Common Stock (or other securities) of the Company. Each Holder further agrees
not to sell or otherwise transfer or dispose of any Common Stock (or other
securities) of the Company held by it during such period of time following the
effective date of an underwritten public offering of the Company's securities as
the underwriters in such underwritten offering deem appropriate; providing,
however, that no such market stand off agreement shall be required of any Holder
(i) who is not identified as a selling shareholder on the registration statement
for such underwritten offering or any other registration statement filed by the
Company pursuant to Sections 2, 3 or 4 hereof and (ii) unless the underwriters
in such underwritten offering shall have requested that the Company's executive
officers and directors enter into similar agreements; provided, however, that in
no event shall such period be more than 90 days. The Company may impose
stop-transfer instructions with respect to the shares (or securities) subject to
the foregoing restriction until the end of such period.



                                       14

         11.      Indemnification.

         (a)      In the event of the offer and sale of Registrable Securities
held by Holders under the 1933 Act, the Company shall, and hereby does,
indemnify and hold harmless, to the fullest extent permitted by law, each
Holder, its directors, officers, partners, each other person who participates as
an underwriter in the offering or sale of such securities, and each other
Person, if any, who controls or is under common control with such Holder or any
such underwriter within the meaning of Section 15 of the 1933 Act, against any
losses, claims, damages or liabilities, joint or several, and expenses to which
the Holder or any such director, officer, partner or underwriter or controlling
person may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages, liabilities or expenses (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such shares were registered
under the 1933 Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading or any violation by the
Company of any federal, state or common law rule or regulation applicable to the
Company and relating to action required of or inaction by the Company in
connection with any such registration, and the Company shall reimburse the
Holder, and each such director, officer, partner, underwriter and controlling
person for any legal or any other expenses reasonably incurred by them in
connection with investigating, defending or settling any such loss, claim,
damage, liability, action or proceeding; provided that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out of
or is based upon an untrue statement or alleged untrue statement in or omission
or alleged omission from such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company through an instrument duly executed by or on behalf of such Holder
specifically stating that it is for use in the preparation thereof. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Holders, or any such director, officer, partner,
underwriter or controlling person and shall survive the transfer of such shares
by the Holder.

         (b)      The Company may require, as a condition to including any
Registrable Securities to be offered by a Holder in any registration statement
filed pursuant to this Agreement, that the Company shall have received an
agreement from such Holder to be bound by the terms of this Section 11,
including an undertaking reasonably satisfactory to it from such Holder, to
indemnify and hold the Company, its directors and officers and each other
Person, if any, who controls the Company within the meaning of Section 15 of the
1933 Act, against any losses, claims, damages or liabilities, joint or several,
to which the Company or any such director or officer or controlling person may
become subject under the 1933 Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement in or omission or alleged omission from
such





                                       15
>PAGE>   60

registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, if such
statement or alleged statement or omission or alleged omission was made in
reliance upon and in conformity with written information about such Holder as a
Holder of the Company furnished to the Company through an instrument duly
executed by such Holder specifically stating that it is for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement; provided, however, that
such indemnity agreement found in this Section 11(b) shall in no event exceed
the gross proceeds from the offering received by such Holder. Such indemnity
shall remain in full force and effect, regardless of any investigation made by
or on behalf of the Company or any such director, officer or controlling person
and shall survive the transfer by any Holder of such shares.

         (c)      Promptly after receipt by an indemnified party of notice of
the commencement of any action or proceeding involving a claim referred to in
Section 11(a) or (b) hereof (including any governmental action), such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the indemnifying party of the
commencement of such action; provided that the failure of any indemnified party
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under Section 11(a) or (b) hereof, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist or the indemnified party may have
defenses not available to the indemnifying party in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties arises in respect of such claim after the
assumption of the defenses thereof, other than reasonable costs of
investigation. Neither an indemnified nor an indemnifying party shall be liable
for any settlement of any action or proceeding effected without its consent. No
indemnifying party shall, without the consent of the indemnified party, consent
to entry of any judgment or enter into any settlement which 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 in respect of such claim or
litigation. Notwithstanding anything to the contrary set forth herein, and
without limiting any of the rights set forth above, in any event any party shall
have the right to retain, at its own expense, counsel with respect to the
defense of a claim.

         (d)      The indemnification required by Section 11(a) and (b) hereof
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expenses,
losses, damages or liabilities are incurred.



                                       16

         (e)      If the indemnification provided for in this Section 11 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage or expense referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense as is
appropriate to reflect the proportionate relative fault of the indemnifying
party on the one hand and the indemnified party on the other (determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission relates to information supplied by the
indemnifying party or the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission), or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law or provides a lesser sum to the
indemnified party than the amount hereinafter calculated, not only the
proportionate relative fault of the indemnifying party and the indemnified
party, but also the relative benefits received by the indemnifying party on the
one hand and the indemnified party on the other, as well as any other relevant
equitable considerations. No indemnified party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any indemnifying party who was not guilty
of such fraudulent misrepresentation.

         (f)      Other Indemnification. Indemnification similar to that
specified in the preceding subsections of this Section 11 (with appropriate
modifications) shall be given by the Company and each Holder of Registrable
Securities with respect to any required registration or other qualification of
securities under any federal or state law or regulation or governmental
authority other than the Securities Act.

         12.      Miscellaneous

         (a)      Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Georgia applicable to
contracts between Georgia residents entered into and to be performed entirely
within the State of Georgia.

         (b)      Successors and Assigns. Except as otherwise provided herein,
the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, executors and administrators of the parties hereto. In the
event the Company merges with, or is otherwise acquired by, a direct or indirect
subsidiary of a publicly-traded company, the Company shall condition the merger
or acquisition on the assumption by such parent company of the Company's
obligations under this Agreement.

         (c)      Entire Agreement. This Agreement constitutes the full and
entire understanding and agreement between the parties with regard to the
subjects hereof.

         (d)      Notices, etc. All notices and other communications required or
permitted hereunder shall be given in writing and shall be deemed effectively
given upon personal delivery or three (3) business days following deposit with
the United States Postal Service, by certified mail, return receipt requested,
postage prepaid, or otherwise delivered by hand or by

other address as the Company shall have furnished to the Purchaser and each such
other Holder in writing.

         (e)      Delays or Omissions. No delay or omission to exercise any
right, power or remedy accruing to any Holder of any Registrable Securities,
upon any breach or default of the Company under this Agreement, shall impair any
such right, power or remedy of such Holder nor shall it be construed to be a
waiver of any such breach or default, or an acquiescence therein, or of or in
any similar breach or default thereunder occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring. Any waiver, permit, consent or approval of
any kind or character on the part of any Holder of any breach or default under
this Agreement, or any waiver on the part of any Holder of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to
the extent specifically set forth in such writing. All remedies, either under
this Agreement, or by law or otherwise afforded to any holder, shall be
cumulative and not alternative.

         (f)      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

         (g)      Severability. In the case any provision of this Agreement
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         (h)      Amendments. The provisions of this Agreement may be amended at
any time and from time to time, and particular provisions of this Agreement may
be waived, with and only with an agreement or consent in writing signed by the
Company and by the holders of a majority of the number of shares of Registrable
Securities (or securities convertible into Registrable Securities) outstanding
as of the date of such amendment or waiver. The Purchaser acknowledges that by
the operation of this Section 12(h), the holders of a majority of the
outstanding Registrable Securities may have the right and power to diminish or
eliminate all rights of the Purchaser under this Agreement.

respect to at least 1,000,000 shares of Common Stock that constitute Registrable
Securities (as adjusted for stock splits, stock dividends, recapitalizations and
similar events) the Company will:

         (a)      promptly give written notice of the proposed registration to
all other Holders so they may have an opportunity to consider joining in such
registration, which they may do (subject to the terms and provisions of this
Agreement) at their election within ten (10) days after receipt of the notice of
the proposed registration by the Company; and

         (b)      as soon as practicable, use its reasonable 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 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 all or

together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request given
within ten (10) days after receipt of notice from the Company pursuant to
Section 2(a); provided that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 2:

                  (i)      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;

                  (ii)     Prior to the date which is the earlier of (a) one
hundred eighty (180) days following the effective date of the registration
statement relating to an Initial Public Offering or (b) the release by the
underwriters of such offering of the related lock-up agreements;



                                       3
>PAGE>   67

                  (iii)    Within the one hundred twenty (120) day period
immediately following the effective date of a registration statement pertaining
to a firm commitment underwritten public offering of Common Stock for its own
account or for the account of another shareholder of the Company who has
exercised a demand right to register shares of Common Stock (other than a
registration relating solely to a Commission Rule 145 transaction, a
registration relating solely to employee benefit plans, or a registration
statement on Form S-3 (or any similar short-form registration statement));

                  (iv)     Within the sixty (60) day period immediately
following the effective date of a registration statement on Form S-3 (or any
similar short-form registration statement) pertaining to a firm commitment
underwritten public offering of Common Stock for its own account or for the
account of another shareholder of the Company who has exercised a demand right
to register shares of Common Stock (other than a registration relating solely to
a Commission Rule 145 transaction or a registration relating solely to employee
benefit plans); or

                  (v)      After the Company has effected three (3)
registrations pursuant to this Section 2 and such registrations have been
declared or ordered effective and have remained effective for a period of at
least ninety (90) consecutive days.

         Subject to the foregoing clauses (i) through (v), 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. The Initiating Holders may, at any time prior to the
effective date of the registration statement relating to such registration,
revoke such request, without liability (except as set forth in Section 6 hereof)
to the Initiating Holders or any other Holders of Registrable Securities
requested to be registered pursuant to Section 2(a) hereof, by providing a
written notice to the Company revoking such request.

         Notwithstanding the above, the Company shall not be obligated to
effect, or to take any action to effect, any registration pursuant to this
Section 2 during the period starting with the date ninety (90) days prior to the
Company's good faith estimate of the date of filing of (or in the case of any
registration on Form S-3, forty-five (45) days prior), and ending on a date [one
hundred twenty(120) days after the effective date of (or in the case of any
registration on Form S-3, ninety (90) days after), a Company-initiated
registration statement in connection with a bona fide firm commitment
underwritten registration for securities to be offered for the Company's own
account (the "Intended Registration"); provided that the Company is actively
employing in good faith all reasonable efforts to cause the Intended
Registration to become effective and provided further that the Company gives
notice to all Holders upon commencement of such period. The Holders shall be
entitled to exercise their rights pursuant to Section 4 hereof with respect to
an Intended Registration. An Intended Registration shall not be deemed to be a
demand registration of the Holders pursuant to this Section 2.

         (c)      Underwriting. If the Holders propose an underwritten offering,
the sale of Registrable Securities pursuant to this Section 2 must be made by
means of a firm commitment underwriting through underwriters who are reasonably
acceptable to the Company and the




                                       4
>PAGE>   68

holders of a majority of the Registrable Securities that are proposed to be
distributed through such underwriting. The right of any Holder to registration
pursuant to this Section 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 requested by such Holder (unless mutually
otherwise agreed by a majority in interest of the Holders and such Holder) to
the extent provided herein.

         The Company and all Holders proposing to distribute Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting. Notwithstanding any other provision of this Section 2(c), if the
underwriter determines that in its good faith view marketing factors require a
limitation of the number of shares to be underwritten and so advises the
Initiating Holders in writing, then the Initiating Holders shall so advise the
Company and all Holders (except those Holders who have indicated to the Company
their decision not to distribute any of their Registrable Securities through
such underwriting) and the number of Registrable Securities that may be included
in the registration and underwriting shall be allocated first to the Holders on
a pro rata basis according to the number of Registrable Securities requested to
be included by the Holders; second to the Company; and third to other
shareholders of the Company who have requested to sell in the registration. No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. If at
least eighty percent (80%) of the Registrable Securities requested to be
registered by the Initiating Holders are not included in such registration, then
the Initiating Holders may request that the Company effect an additional
registration under the Securities Act of all or part of the Initiating Holders'
Registrable Securities in accordance with the provisions of this Section 2, and
the Company shall effect such additional registration.

         If any Holder 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 Registrable Securities and/or other
securities so withdrawn from such underwriting shall also be withdrawn from such
registration; provided, however, that, if by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used above in determining the
underwriter limitation.

         If the underwriter has not limited the number of Registrable Securities
to be underwritten, the Company may include securities for its own account or
the account of others in such registration if the underwriter so agrees and if
the number of Registrable Securities which would otherwise have been included in
such registration and underwriting will not thereby be limited.



                                       5
>PAGE>   69

         (d)      If the Company shall furnish to the Initiating Holders a
certificate signed by the President of the Company stating that, in the good
faith judgment of the Board of Directors of the Company, it would (because of
the existence of, or in anticipation of, any acquisition, financing activity, or
other transaction involving the Company, or the unavailability for reasons
beyond the Company's control of any required financial statements, disclosure of
information which is in its best interest not to publicly disclose, or any other
event or condition of similar significance to the Company) be seriously
detrimental to the Company and its shareholders for such registration statement
to be filed on or before the date filing would be required and it is therefore
essential to defer the filing of such registration statement, then the Company
may direct that such request for registration be delayed for a period not in
excess of ninety (90) days, such right to delay a request to be exercised by the
Company not more than twice in any twelve (12) month period.

         (e)      Effective Registration Statement. A demand registration
requested pursuant to this Section 2 shall not be deemed to have been effected
unless the registration statement relating thereto (i) has become effective
under the Securities Act and any of the Registrable Securities of the Initiating
Holders included in such registration have actually been sold thereunder, and
(ii) has remained effective for a period of at least ninety (90) days (or such
shorter period in which all Registrable Securities included in such registration
have actually been sold thereunder).

         3.       S-3 Registration. In case the Company shall receive from any
Holder or Holders a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will:

         (a)      promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

         (b)      as soon as practicable, and in any event within 30 days of the
receipt of such notice, file a registration statement on Form S-3 and effect all
other qualifications and compliances as may be so requested and as would permit
or facilitate the sale, distribution, transfer or hedging (through market
transactions using brokers, in a firm commitment underwriting, in negotiated
transactions or otherwise) of all or such portion of such Holder's or Holders'
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within 15
days after receipt of such written notice from the Company; provided, that the
Company shall not be obligated to effect any such registration, qualification or
compliance pursuant to this Section 3:

                  (i)      if Form S-3 is not available for such offering by the
Holders;

                  (ii)     if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to register Registrable Securities and such other securities (if any) at
an aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $20 million;



                                       6
>PAGE>   70

                  (iii)    if the Company has, within the twelve (12) month
period preceding the date of such request, already effected three (3)
registrations on Form S-3 for the Holders pursuant to this Section 1.3; or

                  (iv)     in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.

         (c)      Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders and shall keep it continuously effective
until such Registrable Securities have been sold pursuant thereto.

         (d)      Notwithstanding the other provisions of this Section 3, the
Company shall have the right to delay the filing of any registration statement
on Form S-3 (an "S-3 Registration") otherwise required to be prepared and filed
by the Company pursuant to this Section 3, or to suspend the use of any S-3
Registration, for a period not in excess of 60 days (a "S-3 Blackout Period") if
the Company, in the good faith judgment of its Board of Directors, determines
(because of the existence of, or in anticipation of, any acquisition, financing
activity, or other transaction involving the Company, or the unavailability for
reasons beyond the Company's control of any required financial statements,
disclosure of information which is in its best interest not to publicly
disclose, or any other event or condition of similar significance to the
Company) that the registration and distribution of the Registrable Securities to
be covered by such S-3 Registration would be seriously detrimental to the
Company and its shareholders, provided that the S-3 Blackout Period shall
earlier terminate upon the completion or abandonment of the relevant financing,
acquisition or other transaction or upon public disclosure by the Company or
public admission by the Company of such material nonpublic information or such
time as such material nonpublic information shall be publicly disclosed; and
provided, further, that the Company shall furnish to the Holders a certificate
of an executive officer of the Company to the effect that an event permitting a
S-3 Blackout Period has occurred (and no other reason need be given). The
Company will promptly give the Holders written notice of such determination and
an approximation of the period of the anticipated delay; provided, however, that
the aggregate number of days included in all S-3 Blackout Periods during any
consecutive 12 months shall not exceed 180 days. Each Holder agrees to cease all
disposition efforts under such S-3 Registration with respect to Registrable
Securities held by such Holder immediately upon receipt of notice of the
beginning of any S-3 Blackout Period. The Company shall provide written notice
to the Holders of the end of each S-3 Blackout Period.

         4.       Piggyback Registration.

         (a)      If the Company shall determine to register for sale for cash
any of its Common Stock, for its own account or for the account of others (other
than the Holders), other than a



                                       7
>PAGE>   71

registration relating solely to employee benefit plans or securities issued or
issuable to employees, consultants (to the extent the securities owned or to be
owned by such consultants could be registered on Form S-8) or any of their
Family Members (including a registration on Form S-8), or a registration
relating solely to a Commission Rule 145 transaction, a registration on Form S-4
in connection with a merger, acquisition, divestiture, reorganization or similar
event, the Company promptly will give to each Holder written notice thereof and
shall use its best efforts to 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 within ten (10) days after receipt of such written notice from
the Company, by any Holder or Holders. However, the Company may, without the
consent of the Holders, withdraw such registration statement prior to its
becoming effective if the Company has abandoned its proposal to register the
securities proposed to be registered thereby.

         (b)      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 Section 4(a). In such event the right of any Holder to registration
pursuant to Section 4(a) 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 any other shareholders of the Company distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by the
Company. Notwithstanding any other provision of this Section 4(b), if the
underwriter or the Company determines that marketing factors require a
limitation of the number of shares to be underwritten, the underwriter may
exclude some or all Registrable Securities from such registration and
underwriting. The Company shall so advise all Holders (except those Holders who
have indicated to the Company their decision not to distribute any of their
Registrable Securities through such underwriting), and the number of shares of
Registrable Securities that may be included in the registration and
underwriting, if any, shall be allocated among such Holders as follows:

                  (i)      In the event of a piggyback registration pursuant to
Section 4(a) that is initiated by the Company, then the number of shares that
may be included in the registration and underwriting shall be allocated first to
the Company and then to all selling shareholders, including the Holders, who
have requested to sell in the registration on a pro rata basis according to the
number of shares requested to be included; and





                                       8
>PAGE>   72

                  (ii)     In the event of a piggyback registration pursuant to
Section 4(a) that is initiated by the exercise of demand registration rights by
a shareholder or shareholders of the Company (other than the Holders), then the
number of shares that may be included in the registration and underwriting shall
be allocated first to such selling shareholders who exercised such demand and
then to all selling shareholders, including the Holders, who have requested to
sell in the registration, on a pro rata basis according to the number of shares
requested to be included;

provided, however, that in no event shall the total number of shares included in
the offering by any of HBO & Company of Georgia ("HBOC") and Premiere
Technologies, Inc. ("Premiere") 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
securities held by HBOC and Premiere requested to be included in such offering
are included in such offering or unless HBOC and Premiere waive such limitation
or choose not to sell any shares in such registration, and the number of shares
that Holders would otherwise be entitled to include in such registration may be
reduced to give effect to this requirement.

         (c)      No Registrable Securities excluded from the underwriting by
reason of the underwriter's marketing limitation shall be included in such
registration. If any Holder disapproves of the terms of any such underwriting,
such person may elect to withdraw therefrom by written notice to the Company and
the underwriter. The Registrable Securities and/or other securities so withdrawn
from such underwriting shall also be withdrawn from such registration; provided,
however, that, if by the withdrawal of such Registrable Securities a greater
number of Registrable Securities held by other Holders may be included in such
registration (up to the maximum of any limitation imposed by the underwriters),
then the Company shall offer to all Holders who have included Registrable
Securities in the registration the right to include additional Registrable
Securities pursuant to the terms and limitations set forth herein in the same
proportion used above in determining the underwriter limitation.

         5.       Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to Section 2, 3 or
4 hereof, the Company will keep each Holder advised in writing as to the
initiation of each registration, qualification and compliance and as to the
completion thereof. At its expense, the Company will use its best efforts to:

         (a)      prepare and file with the Commission within ninety (90) days
(or in the case of any registration on Form S-3, thirty (30) days) after receipt
of a request for registration with respect to such Registrable Securities, a
registration statement on any form for which the Company then qualifies or which
counsel for the Company shall deem appropriate, subject to Section 2 hereof, and
which form shall be available for the sale of the Registrable Securities in
accordance with the intended method(s) of distribution thereof, and use its best
efforts to cause such registration statement to become and remain effective;
provided that before filing with the Commission a registration statement or
prospectus or any amendments or supplements thereto, including documents
incorporated by reference after the initial filing of any registration
statement, the Company shall (i) furnish to the underwriters, if any, and to one
(1) counsel




                                       9
>PAGE>   73

selected by the Holders of a majority of the Registrable Securities covered by
such registration statement copies of all such documents proposed to be filed,
which documents shall be subject to the review of the underwriters and such
counsel, and (ii) notify each Holder of Registrable Securities covered by such
registration statement of any stop order issued or threatened by the Commission
and take all reasonable actions required to prevent the entry of such stop order
or to remove it if entered;

         (b)      prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
a period of not less than ninety (90) days or such shorter period which shall
terminate when all Registrable Securities covered by such registration statement
have been sold (but not before the expiration of the 90-day period referred to
in Section 4(3) of the Securities Act and Rule 174, or any successor thereto,
thereunder, if applicable), and comply with the provisions of the Securities Act
with respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended method(s) of
disposition by the sellers thereof set forth in such registration statement;

         (c)      furnish, without charge, to each Holder and each underwriter,
if any, of Registrable Securities covered by such registration statement one (1)
signed copy of such registration statement, each amendment and supplement
thereto (including one (1) conformed copy to each Holder and one (1) signed copy
to each managing underwriter and in each case including all exhibits thereto),
and such number of copies of the prospectus included in such registration
statement (including each preliminary prospectus and any other prospectus filed
under Rule 424 under the Securities Act) as such Holders may request, in
conformity with the requirements of the Securities Act, and such other documents
as such Holder may reasonably request in order to facilitate the disposition of
the Registrable Securities owned by such Holder, but only while the Company
shall be required under the provisions hereof to cause the registration
statement to remain effective;

         (d)      use its best efforts to register or qualify such Registrable
Securities under such other applicable securities or blue sky laws of such
jurisdictions as any Holder, and underwriter, if any, of Registrable Securities
covered by such registration statement reasonably requests as may be necessary
for the marketability of the Registrable Securities (such request to be made by
the time the applicable registration statement is deemed effective by the
Commission) and do any and all other acts and things which may be reasonably
necessary or advisable to enable such Holder and each underwriter, if any, to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by such Holder; provided that the Company shall not be required to (i)
qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph (d), (ii) subject itself
to taxation in any such jurisdiction, or (iii) consent to general service of
process in any such jurisdiction;

         (e)      use its best efforts to cause the Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies



                                       10
>PAGE>   74

or authorities as may be necessary by virtue of the business and operations of
the Company to enable the Holder or Holders thereof to consummate the
disposition of such Registrable Securities;

         (f)      immediately notify the managing underwriter, if any, and each
Holder of such Registrable Securities at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event which comes to the Company's attention if as a result of such event
the prospectus included in such registration statement contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading and
the Company shall promptly prepare and furnish to such Holder a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus shall not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading,
unless suspension of the use of such prospectus otherwise is authorized herein
or in the event of a S-3 Blackout Period, in which case no supplement or
amendment need be furnished;

         (g)      use its best efforts to cause all such Registrable Securities
covered by the registration statement to be listed on the Nasdaq Stock Market or
the national securities exchange on which similar securities issued by the
Company are then listed, and enter into such customary agreements including a
listing application and indemnification agreement in customary form (provided
that the applicable listing requirements are satisfied), and to provide a
transfer agent and registrar for such Registrable Securities covered by such
registration statement no later than the effective date of such registration
statement;

         (h)      enter into such customary agreements (including an
underwriting agreement in customary form) and take all such other actions as the
Initiating Holders or the underwriters retained by such Holders, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities, including customary indemnification;

         (i)      make available for inspection during normal business hours by
any Holder of Registrable Securities covered by such registration statement, any
underwriter participating in any disposition pursuant to such registration
statement, and any attorney, accountant or other agent retained by any such
Holder or underwriter (collectively, the "Inspectors"), all financial and other
records, pertinent corporate documents and properties of the Company and its
subsidiaries (collectively, "Records"), if any, as shall be reasonably necessary
to enable them to exercise their due diligence responsibility, and cause the
Company's and its subsidiaries' officers, directors and employees to supply all
information and respond to all inquiries reasonably requested by any such
Inspector in connection with such registration statement. Notwithstanding the
foregoing, the Company shall have no obligation to disclose any Records to the
Inspectors in the event the Company determines that such disclosure is
reasonably likely to have an adverse effect on the Company's ability to assert
the existence of an attorney-client privilege with respect thereto;



                                       11
>PAGE>   75

         (j)      use its best efforts to obtain a "comfort" letter from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by "comfort" letters as the Holders of a
majority (by number of shares) of the Registrable Securities being sold
reasonably request, and provided that such request is reasonable in the
underwriter's point of view;

         (k)      use its best efforts to obtain an obtain an opinion of counsel
from the Company's counsel in customary form and covering such matters of the
type customarily covered in opinions of counsel in connection with such
transactions;

         (l)      comply, and continue to comply during the period that such
registration statement is effective under the Securities Act, in all material
respects with the Securities Act and the Securities Exchange Act of 1934 and
with all applicable rules and regulations of the Commission with respect to the
disposition of all securities covered by such registration statement, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve (12) months, but not
more than eighteen (18) months, beginning with the first full calendar month
after the effective date of such registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act,
and not file any amendment or supplement to such registration statement or
prospectus to which Holder shall have reasonably objected on the grounds that
such amendment or supplement does not comply in all material respects with the
requirements of the Securities Act, having been furnished with a copy thereof at
least five (5) business days prior to the filing thereof; and

         (m)      in the event the offering is underwritten, develop a
presentation reasonably acceptable to the underwriters to facilitate the
offering and to make its chief executive officer and chief financial officer
available for participation in such meetings and presentations (e.g., road show
for the offering) at such locations (including Europe) as the underwriter
reasonably requests.

Each Holder of Registrable Securities agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
5(f) hereof, such Holder shall discontinue disposition of Registrable Securities
pursuant to the registration statement covering such Registrable Securities
until such Holder's receipt of the copies of the supplemented or amended
prospectus contemplated by Section 5(f) hereof, and, if so directed by the
Company, such Holder shall deliver to the Company (at the Company's expense) all
copies (including, without limitation, any and all drafts), other than permanent
file copies, then in such Holder's possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice. In the
event the Company shall give any such notice, the period mentioned in Section
5(b) hereof shall be extended by the greater of (i) ten (10) business days or
(ii) the number of days during the period from and including the date of the
giving of such notice pursuant to Section 5(f) hereof to and including the date
when each Holder of Registrable Securities covered by such registration
statement shall have received the copies of the supplemented or amended
prospectus contemplated by Section 5(f) hereof.



                                       12
>PAGE>   76

         6.       Rule 144. Notwithstanding anything to the contrary contained
herein, no Holder shall have rights to a registration under Section 2, 3 or 4
hereof after the time that such Holder could sell, within thirty (30) days, all
of its Registrable Securities pursuant to Rule 144(e) promulgated under the
Securities Act or any successor rule thereto; provided that the Company hereby
agrees to take the following actions to ensure the availability of Rule 144 to
each such Holder (or such similar actions as shall be required under any
successor rule thereto):

         (a)      make and keep public information available as those terms are
understood and defined in Rule 144;

         (b)      use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

         (c)      so long as any Holder owns any Registrable Securities, furnish
to a Holder upon request, a written statement by the Company as to its
compliance with the reporting requirements of Rule 144 (at any time from and
after ninety (90) days following the effective date of the registration
statement relating to an Initial Public Offering), and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents so filed as the Holder may
reasonably request.

         7.       Registration Expenses. The Company shall pay all expenses in
connection with any registration, including, without limitation, all
registration, filing and NASD fees, printing expenses, all fees and expenses of
complying with securities or blue sky laws, the fees and disbursements of one
counsel for the Holders and the fees and disbursements of counsel for the
Company and of its independent accountants; provided that, in any registration,
each party shall pay for its own underwriting discounts and commissions and
transfer taxes. The Company shall not, however, be required to pay for expenses
of any registration proceeding begun pursuant to Section 2, 3 or 4 hereof, the
request of which has been subsequently withdrawn by the Initiating Holders
(unless the withdrawal is based upon material adverse information concerning the
Company of which the Initiating Holders were unaware at the time of such
request), in which case such expenses shall be borne by the Holders whose
securities were to be included in the registration in proportion to the number
of shares for which such registration was requested.

         8.       Assignment of Rights. Any Holder may assign its rights under
this Agreement to any party acquiring 250,000 shares or more of Registrable
Securities; provided, however, that a Holder may assign its rights under this
Agreement without such restrictions to a transferee or assignee that controls,
is controlled by or is under common control with such Holder.



                                       13
>PAGE>   77

         9.       Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing.

         10.      "Market Stand-off" Agreement. Each Holder agrees not to sell
or otherwise transfer or dispose of any Common Stock (or other securities) of
the Company held by it during the 180 day period following the effective date of
the Initial Public Offering if so requested by the Company and underwriters of
Common Stock (or other securities) of the Company. The Company may impose
stop-transfer instructions with respect to the shares (or securities) subject to
the foregoing restriction until the end of such period.

         11.      Indemnification.

         (a)      In the event of the offer and sale of Registrable Securities
held by Holders under the 1933 Act, the Company shall, and hereby does,
indemnify and hold harmless, to the fullest extent permitted by law, each
Holder, its directors, officers, partners, each other person who participates as
an underwriter in the offering or sale of such securities, and each other
Person, if any, who controls or is under common control with such Holder or any
such underwriter within the meaning of Section 15 of the 1933 Act, against any
losses, claims, damages or liabilities, joint or several, and expenses to which
the Holder or any such director, officer, partner or underwriter or controlling
person may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages, liabilities or expenses (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such shares were registered
under the 1933 Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading or any violation by the
Company of any federal, state or common law rule or regulation applicable to the
Company and relating to action required of or inaction by the Company in
connection with any such registration, and the Company shall reimburse the
Holder, and each such director, officer, partner, underwriter and controlling
person for any legal or any other expenses reasonably incurred by them in
connection with investigating, defending or settling any such loss, claim,
damage, liability, action or proceeding; provided that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out of
or is based upon an untrue statement or alleged untrue statement in or omission
or alleged omission from such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company through an instrument duly executed by or on behalf of such Holder
specifically stating that it is for use in the preparation thereof. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Holders, or any such director, officer, partner,
underwriter or controlling person and shall survive the transfer of such shares
by the Holder.



                                       14
>PAGE>   78

         (b)      The Company may require, as a condition to including any
Registrable Securities to be offered by a Holder in any registration statement
filed pursuant to this Agreement, that the Company shall have received an
agreement from such Holder to be bound by the terms of this Section 11,
including an undertaking reasonably satisfactory to it from such Holder, to
indemnify and hold the Company, its directors and officers and each other
Person, if any, who controls the Company within the meaning of Section 15 of the
1933 Act, against any losses, claims, damages or liabilities, joint or several,
to which the Company or any such director or officer or controlling person may
become subject under the 1933 Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement in or omission or alleged omission from
such registration statement, any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto, if
such statement or alleged statement or omission or alleged omission was made in
reliance upon and in conformity with written information about such Holder as a
Holder of the Company furnished to the Company through an instrument duly
executed by such Holder specifically stating that it is for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement; provided, however, that
such indemnity agreement found in this Section 11(b) shall in no event exceed
the gross proceeds from the offering received by such Holder. Such indemnity
shall remain in full force and effect, regardless of any investigation made by
or on behalf of the Company or any such director, officer or controlling person
and shall survive the transfer by any Holder of such shares.

         (c)      Promptly after receipt by an indemnified party of notice of
the commencement of any action or proceeding involving a claim referred to in
Section 11(a) or (b) hereof (including any governmental action), such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the indemnifying party of the
commencement of such action; provided that the failure of any indemnified party
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under Section 11(a) or (b) hereof, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist or the indemnified party may have
defenses not available to the indemnifying party in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties arises in respect of such claim after the
assumption of the defenses thereof, other than reasonable costs of
investigation. Neither an indemnified nor an indemnifying party shall be liable
for any settlement of any action or proceeding effected without its consent. No
indemnifying party shall, without the consent of the indemnified party,




                                       15
>PAGE>   79

consent to entry of any judgment or enter into any settlement which 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 in respect of such
claim or litigation. Notwithstanding anything to the contrary set forth herein,
and without limiting any of the rights set forth above, in any event any party
shall have the right to retain, at its own expense, counsel with respect to the
defense of a claim.

         (d)      The indemnification required by Section 11(a) and (b) hereof
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expenses,
losses, damages or liabilities are incurred.

         (e)      If the indemnification provided for in this Section 11 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage or expense referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense as is
appropriate to reflect the proportionate relative fault of the indemnifying
party on the one hand and the indemnified party on the other (determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission relates to information supplied by the
indemnifying party or the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission), or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law or provides a lesser sum to the
indemnified party than the amount hereinafter calculated, not only the
proportionate relative fault of the indemnifying party and the indemnified
party, but also the relative benefits received by the indemnifying party on the
one hand and the indemnified party on the other, as well as any other relevant
equitable considerations. No indemnified party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any indemnifying party who was not guilty
of such fraudulent misrepresentation.

         (f)      Other Indemnification. Indemnification similar to that
specified in the preceding subsections of this Section 11 (with appropriate
modifications) shall be given by the Company and each Holder of Registrable
Securities with respect to any required registration or other qualification of
securities under any federal or state law or regulation or governmental
authority other than the Securities Act.

         12.      Miscellaneous

         (a)      Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Georgia applicable to
contracts between Georgia residents entered into and to be performed entirely
within the State of Georgia.

         (b)      Successors and Assigns. Except as otherwise provided herein,
the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, executors and administrators of the parties hereto. In the
event the Company merges with, or is otherwise



                                       16
>PAGE>   80

acquired by, a direct or indirect subsidiary of a publicly-traded company, the
Company shall condition the merger or acquisition on the assumption by such
parent company of the Company's obligations under this Agreement.

         (c)      Entire Agreement. This Agreement constitutes the full and
entire understanding and agreement between the parties with regard to the
subjects hereof.

         (d)      Notices, etc. All notices and other communications required or
permitted hereunder shall be given in writing and shall be deemed effectively
given upon personal delivery or three (3) business days following deposit with
the United States Postal Service, by certified mail, return receipt requested,
postage prepaid, or otherwise delivered by hand or by messenger, addressed: (a)
if to a Purchaser, at the address set forth opposite such Purchaser's name on
Schedule I hereto, or (b) if to any other Holder of any Registrable Securities,
at such address as such holder shall have furnished the Company in writing, or,
until any such Holder so furnishes an address to the Company, then to and at the
address of the last Holder of such Registrable Securities who has so furnished
an address to the Company, or (c) if to the Company, at WebMD, Inc., 400 The
Lenox Building, 3399 Peachtree Road, Atlanta, Georgia 30326, Attn: General
Counsel, with a copy to Nelson Mullins Riley & Scarborough, L.L.P., Bank of
America Corporate Center, Suite 2600, 100 North Tryon Street, Charlotte, North
Carolina 28202, Attn: H. Bryan Ives III and C. Mark Kelly, or at such other
address as the Company shall have furnished to the Purchasers and each such
other Holder in writing.

         (e)      Delays or Omissions. No delay or omission to exercise any
right, power or remedy accruing to any Holder of any Registrable Securities,
upon any breach or default of the Company under this Agreement, shall impair any
such right, power or remedy of such Holder nor shall it be construed to be a
waiver of any such breach or default, or an acquiescence therein, or of or in
any similar breach or default thereunder occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring. Any waiver, permit, consent or approval of
any kind or character on the part of any Holder of any breach or default under
this Agreement, or any waiver on the part of any Holder of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to
the extent specifically set forth in such writing. All remedies, either under
this Agreement, or by law or otherwise afforded to any holder, shall be
cumulative and not alternative.

         (f)      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

         (g)      Severability. In the case any provision of this Agreement
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         (h)      Amendments. The provisions of this Agreement may be amended at
any time and from time to time, and particular provisions of this Agreement may
be waived, with and



                                       17

only with an agreement or consent in writing signed by the Company and by the
holders of a majority of the number of shares of Registrable Securities (or
securities convertible into Registrable Securities) outstanding as of the date
of such amendment or waiver. The Purchasers acknowledge that by the operation of
this Section 12(h), the holders of a majority of the outstanding Registrable
Securities may have the right and power to diminish or eliminate all rights of
any Purchaser under this Agreement.
