         For Value Received, Maurice R. Taylor ("Maker") hereby promises to pay
to the order of MEDgenesis Inc. ("Holder") the principal sum of Six Hundred
Seventy-four Thousand Nine Hundred Dollars ($674,900.00), together with interest
accrued as provided herein, on December 31, 2001. Maker shall pay Holder

interest due before the reduction of principal.

         Maker hereby waives presentment, dishonor, notice of dishonor, and
protest. Any failure of Holder to promptly pursue its remedies herein shall not
discharge Maker of any liabilities. Any event of default herein shall entitle
the Holder to accelerate and receive payment of all outstanding principal and
interest.

         In the event that Holder shall deem it necessary and take any
collection action Maker shall be liable for all costs of collection,
specifically including reasonable attorney fees.

                                PLEDGE AGREEMENT

         This Pledge Agreement is entered by and among Maurice R. Taylor
("Taylor") and MEDgenesis Inc., a Minnesota corporation ("MEDgenesis") effective
July 24, 2000.

         In consideration of a personal loan made by MEDgenesis to Taylor in the
amount of $674,000, as evidenced by Taylor's Promissory Note in that amount and
of even date given to MEDgenesis, and to secure repayment thereof, Taylor and
MEDgenesis agree as follows:

         1. Taylor hereby pledges and assigns to MEDgenesis sums due, now and in
the future, from MEDgenesis to Taylor as compensation for Taylor's employment
with MEDgenesis, according to the terms herein.

         2. MEDgenesis' right to enforce this pledge and recover against
compensation due Taylor shall arise only upon the occurrence of a default by
Taylor under the terms of the Promissory Note, this Pledge Agreement, or the
Residential Mortgage also given by Taylor to MEDgenesis to secure the
indebtedness identified above. The terms of the Promissory Note and Residential
Mortgage are incorporated herein by reference and any default under either of
them shall be deemed a default under this Pledge Agreement.

         3. In the event of a default under this Pledge Agreement, the
Promissory Note or the Residential Mortgage, MEDgenesis shall have the right to
offset and collect against compensation due Taylor without demand or further
process, and Taylor specifically waives any right thereto.

         4. MEDgenesis shall be entitled to offset against and collect
compensation due Taylor in the maximum amount of 25% of each customary payment,
or the highest amount permitted under Minn. Stats. Section 571.922, of all
disposable earnings. Disposable earnings shall be defined as salary due after
all legally required withholdings or deductions, but before any voluntary
employee deductions. Disposable earnings shall not include, and MEDgenesis shall
be entitled to offset and recover against, the entire amount of any sums due,
after legally required deductions, as bonus payments, reimbursements of
expenses, or payment of other perquisites including automobile lease payments or
club membership fees.

         5. So long as any indebtedness remains due under the Promissory Note or
Mortgage, Taylor shall not pledge, assign, or otherwise encumber in favor of any
third party any sums due Taylor as compensation by MEDgenesis.

         6. This Pledge Agreement shall terminate upon repayment in full by
Taylor of all sums due under the Promissory Note and Mortgage.

         THIS PLEDGE AGREEMENT CONSTITUES AN ASSIGNMENT OF WAGES AND TAYLOR
ACKNOWLEDGES THAT HE HAS READ AND
