                                                 Shares of Series A Preferred
                                                 Stock or Common Stock

                             STOCK PURCHASE WARRANT

         THIS CERTIFIES THAT, in consideration of having subscribed for the web
services of MD2patient, Inc., a Georgia corporation (the "Company") and either
having played an important role in the development and market acceptance of our
web site or having referred other physicians who subscribe for our web
services, ______________________ is entitled to purchase from the Company, at
any time during the period specified in Paragraph 2 hereof, ______________
(____) fully paid and non-assessable shares of either Series A Preferred Stock
or Common Stock, par value $.01 per share ("Common Stock"), of the Company, as
determined in accordance with Paragraph 1 hereof, at an exercise price per
share of $1.00 (the "Exercise Price"). The term "Warrant Shares", as used
herein, refers to the _____ shares of either Series A Preferred Stock or Common
Stock, as the case may be, purchasable hereunder. The Warrant Shares and the
Exercise Price are subject to adjustment as provided in Paragraphs 4 and 5
hereof.

         This Warrant is subject to the following terms, provisions and
conditions:

         1.    Manner and Exercise; Issuance of Certificates; Payment for
Shares.

         (a)   Subject to the provisions hereof, this Warrant may be exercised
by the holder hereof, as to all (but not less than all) of the Warrant Shares,
on any one occasion (but on no more than one occasion) within the time period
specified in Paragraph 2 hereof by the surrender of this Warrant, together with
a completed Exercise Agreement in the form attached hereto, to the Company
during normal business hours on any business day at the Company's principal
office in Franklin, Tennessee (or such other office or agency of the Company as
it may designate by notice to the holder hereof), and payment to the Company in
cash, by certified or official bank check or immediately available federal
funds of the full Exercise Price for all of the Warrant Shares. Notwithstanding
the preceding sentence, the holder, at its sole option, may elect (upon
delivery to the Company of satisfactory documentation of such election,
including an opinion of counsel if reasonably required), in lieu of the payment
of the Exercise Price in cash, check or federal funds, to receive from the
Company a lesser number of Warrant Shares having a Fair Market Value on the
date of exercise equal to the difference between (i) the Fair Market Value on
the date of exercise of the full number of Warrant Shares and (ii) the
aggregate Exercise Price of the full number of Warrant Shares (such lesser
number of Warrant Shares so issuable to the holder shall be considered as and
included within the meaning of the term "Warrant Shares" for all remaining
purposes hereof). Prior to the closing of any "Qualified Public Offering" (as
such term is defined in the Company's Articles of Incorporation, as the same
may be amended from time to time), this Warrant shall be exercisable only for
shares of Series A Preferred Stock. From and after the closing of any such
Qualified Public Offering, this Warrant shall be exercisable only for shares of
Common Stock.

         (b)   For purposes of this Paragraph 1, "Fair Market Value" per share
of the Warrant Shares on any date shall be the average of the daily closing
prices per share of the type of

<PAGE>   2

securities for which the Warrant is then exercisable on each of the 20
consecutive trading days through and including the trading day immediately
preceding such date. The closing price per share of any such securities on any
date shall be the last reported sale price, regular way, or, in case no such
sale takes place or is quoted on such date, the average of the closing bid and
asked prices, regular way, for each share of such securities, in either case as
reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the securities are not listed or admitted to trading on the New
York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the securities are listed or admitted to trading
or, if the securities are not listed or admitted to trading on any national
securities exchange, as reported by The Nasdaq Stock Market, Inc.'s Nasdaq
National Market or, if on any such date the securities are not listed or
admitted to trading on any national securities exchange or quoted by The Nasdaq
Stock Market, Inc.'s Nasdaq National Market, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
securities selected by the Board of Directors of the Company; provided,
however, that if on any such date the securities are not listed or admitted to
trading on a national securities exchange or traded in the over-the-counter
market, the closing price per share of such securities on such date shall mean
the fair value per share of securities on such date as determined in good faith
by the Board of Directors of the Company and set forth in a certificate
delivered to the holder.

         (c)   Warrant Shares acquired by the holder hereof shall be deemed to
be issued to the holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been surrendered, the
completed Exercise Agreement (and other documentation reasonably requested by
the Company) delivered, and payment made for such shares as aforesaid.
Certificates for the Warrant Shares so purchased shall be delivered to the
holder hereof within a reasonable time after this Warrant shall have been so
exercised. The certificates so delivered shall be in such denominations as may
be requested by the holder hereof and shall be registered in the name of said
holder unless otherwise specified by the holder in the Exercise Agreement and
consented to by the Company.

         2.    Period of Exercise. This Warrant is exercisable on any one
occasion (but on no more than one occasion) at any time on or after one (1)
year from date of issuance, and before 5:00 p.m. Franklin, Tennessee local time
on the third (3rd) anniversary of the date of issuance. The date of issuance of
this Warrant is ______________, 2000.

         3.    Certain Agreements of the Company. The Company hereby covenants
and agrees as follows:

         (a)   Shares to be Fully Paid. All Warrant Shares will, upon issuance,
be validly issued, fully paid and non-assessable.

         (b)   Reservation of Shares. During the period within which this
Warrant may be exercised, the Company will at all times have authorized, and
reserved for the purpose of issue upon exercise of this Warrant, a sufficient
number of Warrant Shares to provide for the exercise of this Warrant.

         4.    Stock Dividends, Splits, Combinations. If at any time after the
date of the issuance of this Warrant the Company (a) declares a dividend or
other distribution payable in shares of, or securities convertible into shares
of, Series A Preferred Stock (or, following the closing of any Qualified Public
Offering, Common Stock) or subdivides its outstanding shares of

                                     - 2 -
<PAGE>   3

Series A Preferred Stock (or, following the closing of any Qualified Public
Offering, Common Stock) into a larger number or (b) combines its outstanding
shares of Series A Preferred Stock (or, following the closing of any Qualified
Public Offering, Common Stock) into a smaller number, then (i) the number of
Warrant Shares to be delivered upon exercise of this Warrant will, upon the
occurrence of an event set forth in clause (a) above, be increased and, upon the
occurrence of an event set forth in clause (b) above, be decreased so that the
holder of this Warrant will be entitled to receive the number of shares of
Series A Preferred Stock (or, following the closing of any Qualified Public
Offering, Common Stock) that such holder would have owned immediately following
such action had this Warrant been exercised immediately prior thereto and (ii)
the Exercise Price in effect immediately prior to such dividend, other
distribution, subdivision or combination, as the case may be, shall be adjusted
proportionately by multiplying such Exercise Price by a fraction, of which the
numerator shall be the number of Warrant Shares purchasable upon exercise of
this Warrant immediately prior to such adjustment, and of which the denominator
shall be the number of Warrant Shares purchasable immediately thereafter.

         5.    Reorganization, Merger or Sale of Assets. In case of any capital
reorganization or reclassification or other change of outstanding shares of
Series A Preferred Stock (or, following the closing of any Qualified Public
Offering, Common Stock), any consolidation or merger of the Company with or
into another corporation or other entity (other than a consolidation or merger
of the Company in which the Company is the resulting or surviving corporation
and which does not result in any reclassification or change of outstanding
Series A Preferred Stock (or, following the closing of any Qualified Public
Offering, Common Stock)) or the sale of all or substantially all of the assets
of the Company to another corporation or other entity, upon exercise of this
Warrant, the holder of this Warrant shall have the right to receive the kind
and amount of shares of stock or other securities or property to which a holder
of the number of shares of Series A Preferred Stock (or, following the closing
of any Qualified Public Offering, Common Stock) deliverable upon exercise of
this Warrant would have been entitled upon such reorganization,
reclassification, consolidation, merger or sale had this Warrant been exercised
immediately prior to such event; and, in such case, appropriate adjustment (as
determined in good faith by the Board of Directors) shall be made in the
application of the provisions of this Warrant with respect to the rights and
interests thereafter of the holder of this Warrant, to the end that the
provisions set forth in this Warrant (including provisions with respect to
changes in and other adjustments of the Exercise Price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other property thereafter deliverable upon exercise of this Warrant.

         6.    No Rights or Liabilities as a Shareholder. Nothing contained in
this Warrant shall be determined as conferring upon the holder of this Warrant
any rights as a stockholder of the Company or as imposing any liabilities on
such holder to purchase any securities whether such liabilities are asserted by
the Company or by creditors or stockholders of the Company or otherwise.

         7.    Transfer, Exchange and Replacement of Warrant.

         (a)   Warrant Transfer Provisions. THIS WARRANT MAY NOT BE SOLD,
TRANSFERRED, ASSIGNED, HYPOTHECATED OR OTHERWISE DISPOSED OF, UNLESS CONSENTED
TO IN WRITING BY THE COMPANY, AND NO SALE, TRANSFER, ASSIGNMENT, HYPOTHECATION

satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount
to the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

         (c)   Cancellation; Payment of Expenses. Upon the surrender of this
Warrant in connection with any permitted transfer or any replacement as
provided in this Paragraph 7, this Warrant shall be automatically canceled.

         (d)   Register. The Company shall maintain at its principal office in
Franklin, Tennessee (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in
which the Company shall record the name and address of the person in whose name
this Warrant has been issued, as well as the name and address of each permitted
transferee, if any, and each prior owner of this Warrant, if any.

         8.    No Adjustment for Dividends. Except as provided in Paragraph 4
hereof, no adjustment in respect of any dividends shall be made during the term
of this Warrant or upon the exercise of this Warrant. Notwithstanding any other
provision hereof, no adjustments shall be made on Warrant Shares issuable on
the exercise of this Warrant for any cash dividends paid or payable to holders
of record of Series A Preferred Stock or Common Stock prior to the date as of
which the holder of this Warrant shall be deemed to be the record holder of
such Warrant Shares.

         9.    Notices of Corporate Action. So long as this Warrant has not
been exercised, in the event of:

         (a)   any taking by the Company of a record of all holders of Series A

as a director, officer, partner, employee, manager, consultant, agent,
independent contractor, advisor, creditor or equity owner (except for ownership
of less than five percent (5%) of the stock of a publicly-traded company) or
otherwise providing any services for or assistance to any business or

engages in competition with the provision of Internet-based medical content and
healthcare services engaged in by Employer or any subsidiary, division or
affiliate thereof as of the last day of Executive's employment with Employer.

         8.5   "DISCLOSING PROPRIETARY INFORMATION OF EMPLOYER" DEFINED. For
purposes of this Agreement, "disclosing proprietary information of Employer"
shall mean disclosing any item of proprietary information or trade secret of
Employer including, but not limited to, customer lists, sales lists, invoices,
confidential selling and profit information, technology, finances, earnings,
volume of business, outlets, methods, systems, practices, plans, and other

in a manner reasonably expected to provide a competitive advantage to another
party.

         8.6   SEVERANCE PAY. In the event an election not to renew this
Agreement is made by either party pursuant to the provisions of Section 8.1
hereof, or in the event this Agreement is terminated pursuant to the provisions
of Sections 8.2 hereof, Executive's compensation shall cease on the date on
which this Agreement is terminated, and Executive shall be entitled to no
severance pay. In the event this Agreement is terminated pursuant to the
provisions of Section 8.3 hereof, as severance pay for such termination,
Executive shall continue to receive his then-current salary and health benefits
at Company expense for a period of one (1) year following such termination.

SECTION 9.     RESTRICTIVE COVENANT.

         For a period of twelve (12) months following the expiration or
termination of this Agreement for any reason whatever, Executive shall neither
engage in competition with Employer nor disclose proprietary information of
Employer, as those terms are defined in Section 8, hereof, neither shall
Executive solicit or otherwise contact existing subscribers of Employer for
purposes of engaging in competition with Employer. In the event of Executive's
actual or threatened breach of the provisions of this paragraph, Employer shall
be entitled to an injunction restraining Executive therefrom and Executive
hereby consents to such injunction; provided, however, that nothing herein
shall be construed as prohibiting Employer from pursuing any other available
remedies for such breach or threatened breach, including the recovery of
damages from Executive.

SECTION 10.    LIFE INSURANCE.

         Executive acknowledges that Employer shall have the right, at its sole
expense, to procure life insurance on his life of which the Employer or its
designee shall be the sole beneficiary, and

agrees that he shall take all such actions, submit to such examinations, and
execute all such documents as are reasonably necessary to enable Employer to
obtain such coverage.

SECTION 11.    ENTIRE AGREEMENT; AMENDMENTS.

         This Agreement, along with any exhibits or schedules attached hereto
or delivered pursuant hereto, all of which form a part hereof, contain the

may be amended only by a written instrument duly executed by all parties or
their respective heirs, successors, assigns or legal personal representatives.

SECTION 12.    ASSIGNMENT.

         Executive acknowledges that the services to be rendered by him are

rights or delegate any of his duties or obligations under this Agreement.

SECTION 13.    WAIVER OF BREACH.

         Either party may, by written notice to the other: (i) extend the time

(ii) waive compliance with any of the covenants of the other contained in this
Agreement; and (iii) waive or modify performance of any of the obligations of
the other. However, mere forbearance or indulgence by either party in any
regard whatsoever shall not constitute a waiver of the covenant or condition to
be performed by the other party to which the same may apply and, until complete
performance of said covenant or condition, said party shall be entitled to
invoke any remedy available under this Agreement or by law or in equity despite
said forbearance or indulgence.

         Each party shall perform such further acts and execute and deliver
