     2.  Restrictions.  The Shares are subject to each of the restrictions set
         ------------
forth in this Section 2.

     (a) The term "Restricted Shares" means those Shares which are subject to
                   -----------------
the restrictions imposed hereunder which restrictions have not then expired or
terminated pursuant to Section 3 hereof.  Restricted Shares may not be sold,
transferred, exchanged, assigned, pledged, hypothecated or otherwise encumbered,
except as provided herein.  If Grantee's employment with the Company terminates
for any reason other than as set forth in Section 3(b) hereof, then Grantee
shall forfeit all of Grantee's right, title and interest in and to the
Restricted Shares as of the date of employment termination, and such Restricted
Shares shall be transferred back to the Company pursuant to a Stock Assignment
in favor of the Company with respect to the Shares in the form attached hereto
as Exhibit A (the "Stock Assignment"), and without any further act or action by
   ---------       ----------------
Grantee.  Grantee shall execute the Stock Assignment as a condition to receiving
the Shares.

     (b) Grantee hereby agrees that he will be subject to and will comply with
the additional restrictions set forth on Exhibit B (the "Company Restrictions"),
                                         ---------       --------------------
pursuant to the terms thereof.  Grantee also agrees that he is an "accredited
investor" within the meaning of Rule 501 of Regulation D of the Securities Act
of 1933, as amended (the "Act"), as presently in effect.  This Agreement is made
                          ---
with Grantee in reliance upon Grantee's representation to the Company that the
Shares to be received by Grantee will be acquired for investment for Grantee's
own account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and Grantee has no present intention of
selling, granting any participation in, or otherwise distributing the same.  The
Grantee further represents that he does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participation to such person, or to any third person, with respect to the
Shares.  The Grantee has substantial experience in evaluating and investing in
private placement transactions of securities in companies similar to WebMD, Inc.
and USA.NET, Inc. so that he is capable of evaluating the merits and risks of
his
<PAGE>

investment in the Shares and has the capacity to protect his own interests.
Grantee acknowledges and agrees that he must bear the economic risk of this
investment indefinitely unless the Shares are registered pursuant to the Act, or
an exemption from registration is available.  Grantee understands that the
Shares have not been registered under the Act or any applicable state securities
laws and that there is no present intention to register the Shares and that
there is no assurance that any exemption from registration under the Act will be
available.  Grantee has had the opportunity to ask questions of and receive
answers from the Company, WebMD and USA.NET and their respective management
regarding the terms and conditions of this investment.  Grantee acknowledges and
agrees that the Shares are characterized as "restricted securities" under the
federal securities laws, and that he will not sell or otherwise transfer the
Shares, or any portion thereof, without registration under any applicable
federal and state securities laws or an exemption therefrom.

     (c) The restrictions imposed under this Section 2 shall apply to all Shares
or other securities issued with respect to the Shares hereunder in connection
with any merger, reorganization, consolidation, recapitalization, stock dividend
or other change in corporate structure affecting any of the Shares.

  3.  Expiration and Termination of Restrictions.  The restrictions imposed

      --------------------------
shall be entitled to receive currently any and all cash dividends or other cash
income with respect to the Restricted Shares.  Grantee shall have the right to

connection with a Withholding Loan, whether by foreclosure or otherwise, the
pledge or other transferee agrees to be bound by the terms of the Restated
Shareholders Agreement or the Investors' Rights Agreement, as the case may be,
unless such requirement is waived or otherwise amended by the parties to such
agreements. The Restricted Shares are not assignable or transferable by Grantee
other than by will or the laws of descent and distribution.

terminated pursuant to Section 3 hereof.  Restricted Shares may not be sold,
transferred, exchanged, assigned, pledged, hypothecated or otherwise encumbered,
except as provided herein.  If Grantee's employment with the Company terminates
for any reason other than as set forth in Section 3(b) hereof, then Grantee
shall forfeit all of Grantee's right, title and interest in and to the
Restricted Shares as of the date of employment termination, and such Restricted
Shares shall be transferred back to the Company pursuant to a Stock Assignment
in favor of the Company with respect to the Shares in the form attached hereto
as Exhibit A (the "Stock Assignment"), and without any further act or action by
   ---------       ----------------
Grantee.  Grantee shall execute the Stock Assignment as a condition to receiving
the Shares.

     (b) Grantee hereby agrees that he will be subject to and will comply with
the additional restrictions set forth on Exhibit B (the "Company Restrictions"),
                                         ---------       --------------------
pursuant to the terms thereof.  Grantee also agrees that he is an "accredited
investor" within the meaning of Rule 501 of Regulation D of the Securities Act
of 1933, as amended (the "Act"), as presently in effect.  This Agreement is made
                          ---
with Grantee in reliance upon Grantee's representation to the Company that the
Shares to be received by Grantee will be acquired for investment for Grantee's
own account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and Grantee has no present intention of
selling, granting any participation in, or otherwise distributing the same.  The
Grantee further represents that he does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participation to such person, or to any third person, with respect to the
Shares.  The Grantee has substantial experience in evaluating and investing in
private placement transactions of securities in companies similar to WebMD, Inc.
and USA.NET, Inc. so that he is capable of evaluating the merits and risks of
his
<PAGE>

investment in the Shares and has the capacity to protect his own interests.
Grantee acknowledges and agrees that he must bear the economic risk of this
investment indefinitely unless the Shares are registered pursuant to the Act, or
an exemption from registration is available.  Grantee understands that the
Shares have not been registered under the Act or any applicable state securities
laws and that there is no present intention to register the Shares and that
there is no assurance that any exemption from registration under the Act will be
available.  Grantee has had the opportunity to ask questions of and receive
answers from the Company, WebMD and USA.NET and their respective management
regarding the terms and conditions of this investment.  Grantee acknowledges and
agrees that the Shares are characterized as "restricted securities" under the
federal securities laws, and that he will not sell or otherwise transfer the
Shares, or any portion thereof, without registration under any applicable
federal and state securities laws or an exemption therefrom.

     (c)  The restrictions imposed under this Section 2 shall apply to all
Shares or other securities issued with respect to the Shares hereunder in
connection with any merger, reorganization, consolidation, recapitalization,
stock dividend or other change in corporate structure affecting any of the
Shares.

pledge or other transferee agrees to be bound by the terms of the Restated
Shareholders Agreement or the Investors' Rights Agreement, as the case may be,
unless such requirement is waived or otherwise amended by the parties to such
agreements. The Restricted Shares are not assignable or transferable by Grantee
