          Medical Group's designated Medical Director under the MDA;

               (viii) the date upon which the Stockholder ceases to be Medical

          (b) Transfer of Stock.  Immediately, upon the occurrence of a
              -----------------
Transfer Event, the Designated Transferee shall pay to the Stockholder a
purchase price for the Stock transferred pursuant to this Section 2, in
an amount equal to the stated par value of the Stock. Payment of the
purchase price for the Stock shall be made to the Stockholder in cash or
by certified or cashiers check. The time for payment of the purchase price
for any Stock transferred hereunder shall be at 10:00 am on the first

notice, the Designated Transferee shall, upon becoming aware of any such
Transfer Event, promptly notify the Stockholder, Medical Group and DCA of
such Transfer Event and tender to the Stockholder the purchase price for
the Stock). Unless otherwise agreed upon by the

              ----------
"Designated Transferee" shall mean the individual then holding the position

                  --------
certificate has been delivered by the Stockholder upon execution hereof and
has been duly endorsed by the Stockholder in blank.  DCA agrees to hold such
Certificate in trust for the benefit of the Designated Transferee.  Upon the
occurrence of a Transfer Event, DCA shall endorse the Certificate in the name
of the Designated Transferee and shall release the Certificate to the Medical
Group's secretary for cancellation by the secretary, for registration of the
shares represented thereby in the name of the Designated Transferee on the
books of Medical Group, and for issuance of a new certificate in the name of
the Designated Transferee.

              -----------------------------------
to the contrary herein, release of the certificate by DCA to the secretary of
Medical Group shall be contingent on DCA's prior or concurrent receipt of:

               (i)   a stock transfer power executed by the Designated
           Transferee covering the Stock transferred to the Designated
           Transferee;

           evidencing the Designated Transferee's ownership of the Stock in
           Medical Group; and

           Transferee substituting the Designated Transferee for the Stock-
           holder hereunder.

     3. Other Matters.
        -------------

          (a) Upon the occurrence of a Transfer Event, the Stockholder shall
be disqualified as a stockholder of Medical Group, and shall immediately
resign, or be deemed to have resigned, as a Director, as President and as
any other officer of Medical Group.

                                       3



          (b) Upon the occurrence of a Transfer Event, the parties hereto or
their personal representatives and assigns shall do all things and execute
and deliver all papers as may be necessary to consummate the stock transfer,
free and clear of all liens, security interests, claims and encumbrances with
the exception of any security interest remaining under the Loan and Security
Agreement of even date herewith between Medical Group and DCA.

          (c) After occurrence of a Transfer Event, the Stockholder, and any
person other than the Designated Transferee who acquires the Stock, shall
