<PAGE>


such payment on demand. Borrower hereby assigns to Lender all returned or
unearned premiums that may be payable to the Borrower upon cancellation of any
such policies for any reason and all proceeds of such insurance, and directs the
insurers to pay Lender all such amounts. Borrower hereby grants Lender a limited
power of attorney to endorse any check or other remittance payable to Borrower

require that, in addition to the monthly loan payments required under the Notes,
Borrower shall pay to Lender with each such monthly loan payment one-twelfth of
the annual amount of the real estate taxes and assessments assessed against the

and assessments when due, Borrower shall immediately pay Lender amounts
sufficient to allow for payment of the taxes and assessments when due.

for any expenses, costs or claims which Lender may incur relating to its
exercise of any rights under this Agreement or writings contemplated hereby.
Such amounts shall be due and payable upon demand and shall bear interest at the

Borrower notice five days prior to incurring expenses, however, the failure to
give such notice shall not impair Borrower's obligation to reimburse and
indemnify Lender. Borrower shall defend, indemnify and hold Lender harmless from
and against

furnish to Lender (i) immediately upon receipt, copies of any correspondence,
notice, pleading, citation, indictment, complaint, order, decree or other
document from any source asserting or alleging a circumstance or condition which
requires or may require a financial contribution by Borrower or a cleanup,
removal, remedial action or other response by or on the part of Borrower under
Environmental Laws or which seeks damages or civil, criminal or punitive
penalties from Borrower for an alleged violation of Environmental Laws; and (ii)
written notice of any condition or event which would make the warranties
contained in Article IV inaccurate, as soon as Borrower becomes aware of such
condition or event.

                                 PROMISSORY NOTE


$820,000.00                                               Minneapolis, Minnesota
                                                               December 21, 2000


         FOR VALUE RECEIVED, the undersigned Borrower promises to pay to the
order of Equity Holdings II (the "Lender"), at its office in Edina, Minnesota,
or at such other place as the holder of this Note may designate from time to
time, the principal sum of $820,000.00 which remains outstanding as shown in the
records of the holder of this Note, as the case may be, and to pay interest on
the outstanding balance hereof at the times and at the rates set forth below.
This Note is secured by a Combination Real Estate Mortgage, Security Agreement,
Fixture Financing Statement and Assignment of Leases and Rents dated the date
hereof from the undersigned to Lender relating to certain property located in
Minnetonka, Minnesota as more particularly described therein (as amended from
time to time, the "Mortgage"). Lender may make additional subsequent advances at
its discretion but at no time shall Lender advance an amount which would cause
the unpaid principal balance of this Note to exceed $820,000.00.

         Interest on the Note shall accrue on the unpaid principal balance and
on any past due payments thereon at the annual rate of 5.0 percentage points
above the Base Rate as hereinafter defined. The interest rate and payment amount
shall change from time to time as the Base Rate changes. The terms "Base Rate"
means the highest Prime Rate of Interest published by the Wall Street Journal.
If the Wall Street Journal discontinues the public announcement of Prime
Interest Rates for any reason, Lender shall set its own Base Rate and shall so
notify Borrower. Lender may lend to others at rates that are equal to, above or
below the Base Rate. Interest will begin to accrue on the date of the first
advance.

         The remaining principal balance of this Note shall become due and
payable in full on or before December 21, 2002. Monthly payments of interest
only shall commence on January 21, 2001 and shall continue on the 21st day of
each month thereafter until December 21, 2002, at which time the entire balance
of principal and accrued interest shall become due and payable in full. Payments
received by Lender more than 15 days after their due date shall incur a late
payment penalty in the amount of 5% of each such payment which shall become
immediately due.

         Interest on this Note shall be calculated on the basis of actual days
elapsed in a year of 360 days. All of the unpaid balance of this Note may be
prepaid in full at any time. No partial prepayments shall be allowed. The
prepayment amount shall include all accrued interest, costs advanced by Lender,
the full principal balance and all scheduled interest payments for the remaining
term of the Loan. Each monthly payment or prepayment shall be applied first to
the payment of other charges under this

<PAGE>


Note, second to the payment of interest accrued through the date of payment and
third to the payment of principal under this Note.

         In the event of any default in the payment of this Note and the
continuance of such default for a period of 15 days, or the occurrence of an
Event of Default under the terms of the Loan Agreement or any of the other "Loan
Documents" (as such term is defined in the Loan Agreement), or of any other
obligations of the undersigned to the holder of this Note; or in the event any
of the undersigned or any maker, endorser, guarantor or surety of this Note or
any other person providing security for this Note or for any guaranty for this
Note shall become insolvent, make an assignment, make an assignment for the
benefit of creditors, apply for or consent to the application or suffer the
appointment of any receiver, trustee or similar officer, die, or initiate or
have initiated against it any act, process or proceeding under any insolvency,
bankruptcy, dissolution, liquidation or similar law (provided that the filing of
an involuntary petition in bankruptcy against the undersigned, or any of the
guarantors of this Note, shall constitute an event of default only if the
petition is not dismissed within 30 days after filing); or a final judgment or
other order for the payment of money in the amount of $25,000 or more, or any
writ, warrant, attachment, execution or similar process, shall be entered and
become a lien on, issued or levied against, the Premises, or any part thereof
and shall not be released, vacated or fully bonded within forty-five (45) days
after its entry, issue or levy; or the issuance or levy of any writ, warrant,
attachment, execution or similar process against any property of any of the
undersigned or any such maker, endorser, guarantor, surety or other person which
is not released or fully bonded within a period of 30 days; or in the event that
any statement, representation or warranty of any of the undersigned or any such
maker, endorser, guarantor, surety or other person to any holder of this Note at
any time shall prove to have been incorrect or misleading in any material
respect when made; then in any such event the holder of this Note may, at its
option, declare this Note to be immediately due and payable and thereupon this
Note shall become due and payable for the entire unpaid principal balance of
this Note plus accrued interest and other charges on this Note without any
presentment, demand, protest or other notice of any kind.

         Each of the undersigned and each endorser, guarantor and surety of this
Note jointly and severally agree to pay this Note; guarantee payment of this
Note; waive demand, presentment, protest, notice of protest, notice of dishonor
and notice of nonpayment of this Note; consent to any extensions and renewals of
this Note without notice; consent to the release of any of them by the holder of
this Note with or without consideration or notice; exonerate the holder of this
Note from any duty or obligation to make demand on anyone for payment of any
security or delivery of any guaranty for this Note or to give notice to anyone
of nonpayment thereof or to collect or sell the same; consent to the extension,
renewal, exchange, subordination, surrender or release of any security for this
Note by the holder of this Note with or without consideration or notice; agree
that no act, omission or thing, except full payment of this Note, which but for
this provision could act as a release or impairment of their liability, shall in
any way release, impair or affect the liability of any of them; agree to
promptly provide the holder of this Note from time to time with their financial
statements and such


                                       2

other information respecting their financial condition, business and property as
the holder of this Note may request, in form and substance acceptable to the
holder of this Note; agree that when or at any time after this Note becomes due
the holder of this Note may offset or charge the full amount owing on this Note
against any account then maintained by any of them with the holder of this Note
without notice; agree to pay on demand all costs and expenses of the holder of
this Note in connection with this Note and any security and guaranties for this
Note, including without limitation reasonable attorneys' fees, plus interest on
such amounts at the rate set forth in this Note; and consent to the personal
jurisdiction of the state and federal courts located in the State of Minnesota
in connection with any controversy related in any way to this Note or any
security or guaranty for this Note, waive any argument that venue in such forums
is not convenient, and agree that any litigation initiated by any of them
against Lender or any other holder of this Note relating in any way to this Note
or any security or guaranty for this Note shall be venued in either the District
Court of Hennepin County, Minnesota, or the United States District Court,
District of Minnesota, Fourth Division. Interest on any amount under this Note
shall continue to accrue, at the option of the holder of this Note, until such
holder receives final payment of such amount in collected funds in form and
substance acceptable to such holder.

         No waiver of any right or remedy under this Note shall be valid unless
in writing executed by the holder of this Note, and any such waiver shall be
effective only in the specific instance and for the specific purpose given. All
rights and remedies of the holder of this Note shall be cumulative and may be
exercised singly, concurrently or successively. The undersigned, if more than
one, shall be jointly and severally liable under this Note, and the term
"undersigned" wherever used in this Note, shall mean the undersigned or any one
or more of them. This Note shall be governed by and construed in accordance with
the laws of the State of Minnesota.

         THE UNDERSIGNED REPRESENTS, CERTIFIES, WARRANTS AND AGREES THAT THE
UNDERSIGNED HAS READ THIS NOTE IN ITS ENTIRETY AND UNDERSTAND ALL OF THE
PROVISIONS OF THIS NOTE. THE UNDERSIGNED ALSO AGREES THAT THE COMPLIANCE BY ANY
