                                    FORM OF
                                PROMISSORY NOTE
$100,000                                                           June 19, 2000

         FOR VALUE RECEIVED, the undersigned, MD2patient, Inc., promises to pay
to the order of John E. Blount (hereafter, together with any holder hereof,
called "Holder") at the offices of the Holder located at 501 Corporate Centre
Drive, Suite 200, Franklin, TN, or at such other place as the Holder may
designate in writing to the undersigned, in lawful money of the United States of
America, and in immediately available funds, the principal sum of ONE HUNDRED
THOUSAND AND 00/100 DOLLARS ($100,000) together with interest on the principal
balance from time to time outstanding hereunder (computed on the basis of a
360-day year for the actual number of days elapsed) from the date hereof until
paid in full at a per annum rate equal to twelve percent (12%) in simple
interest terms.

         The principal balance shall be payable June 19, 2001. Accrued interest
shall be due and payable on the date the principal balance is due (whether by
acceleration, maturity or otherwise).

         In no event shall the amount of interest due or payable under this Note
exceed the maximum rate of interest allowed by applicable law and, in the event
any such payment is inadvertently paid by the undersigned or inadvertently
received by the Holder, then such excess sum shall be credited as a payment of
principal, unless the undersigned shall notify the Holder in writing that the
undersigned elects to have such excess sum returned to it forthwith. It is the
express intent of the parties hereto that the undersigned not pay and the Holder
not receive, directly or indirectly, in any manner whatsoever, interest in
excess of that which may be lawfully paid by the undersigned under applicable
law.

         Each of the following events shall constitute an "Event of Default"
under this Note: (i) failure of the undersigned to pay any principal, interest
or other amount due hereunder within thirty days of the date such payment is
due, or the undersigned shall in any way fail to comply with the other terms,
covenants or conditions contained in this Note; or (ii) the undersigned shall
(a) commence a voluntary case under the Bankruptcy Code of 1978, as amended, or
other federal bankruptcy law (as now or hereafter in effect), (b) file a
petition seeking to take advantage of any other laws, domestic or foreign,
relating to bankruptcy, insolvency, reorganization, winding up or composition
for adjustment of debts, (c) consent to or fail to contest in a timely and
appropriate manner any petition filed against it in an involuntary case under
such bankruptcy laws or other laws, (d) apply for or consent to, or fail to
contest in a timely and appropriate manner, the appointment of, or the taking of
possession by, a receiver, custodian, trustee, or liquidator of itself or of a
substantial part of its property, domestic or foreign, (e) make a general
assignment for the benefit of creditors or (f) make a conveyance fraudulent as
to creditors under any state or federal law.
