                            REAL ESTATE MORTGAGE NOTE


PRINCIPAL AMOUNT:                                                 TROY, MICHIGAN
$1,400,000.00

DUE DATE: MAY 20, 1999                                 DATED:  NOVEMBER 20, 1998

         FOR VALUE RECEIVED, the undersigned promises to pay to the order of
Crestmark Bank, a Michigan banking corporation, ("Lender") at its offices
located at 850 East Long Lake Road, Troy, Michigan 48098 or at such other place
as Lender may designate in writing, the principal sum of One Million Four
Hundred Thousand and No/100 ($1,400,000.00) Dollars, plus interest as
hereinafter provided, in lawful money of the United States, or such sum as has
been advanced, interest thereon and all expenses then outstanding under this
Note and the Loan Agreement.

         The unpaid principal balance outstanding from time to time under this
Real Estate Mortgage Note ("Note") shall bear interest on a basis of a year of
360 days for the actual number of days elapsed in a month, at a rate equal to
ten percent (10%) per annum (the "Effective Rate").

         The interest hereunder shall be repaid in monthly installments of
interest only, commencing on the first day of December, 1998 and continuing on
the first day of each calendar month thereafter, until May 20, 1999, when the
unpaid principal balance and all accrued interest thereon, if any, shall be due
and payable in full, or such earlier date upon which the indebtedness is due and
payable as a result of acceleration or otherwise (the earlier of such date being
the "Due Date"). The Borrower acknowledges that the monthly payments required
hereunder are not amortized and will not amortize the indebtedness evidenced by
the maturity hereof, and that the final payment due hereunder at maturity will
be a balloon payment of all then outstanding principal and interest. Anything
herein contained to the contrary, notwithstanding, all unpaid principal and
accrued and unpaid interest shall be due and payable in full on the Due Date
above stated.

         The Money Advance and all interest and expenses hereunder shall be
charged to a loan account in Borrower's name on Lender's books (the "Loan
Account"), and Lender shall debit to such account the amount of each loan or
advance when made and credit to such account the amount of each repayment
hereunder. Lender shall render Borrower from time to time a statement of account
setting forth the Borrower's loan balance in said Loan Account which shall be
deemed to be correct and accepted by and binding upon Borrower, unless Lender
receives a written statement of exceptions within ten (10) Business Days after
such statement has been rendered to Borrower. Such statement of account shall be
prima facie evidence of the loans and advances owing to Lender by Borrower
hereunder, together with interest accrued thereon.

         Any payment made by mail will be deemed tendered and received only upon
actual receipt by Lender at the address of Lender designated for such payment
whether or not Lender has authorized payment by mail or any other manner.
Borrower hereby expressly assumes all risk of loss or liability resulting from
non-delivery or delay in delivery of any payment transmitted by mail or in any
other manner.

         No delay or failure of Lender in exercising any right, remedy, power or
privilege hereunder shall affect such right, remedy, power or privilege, nor
shall any single or partial exercise thereof preclude the exercise of any other
right, remedy, power or privilege. No delay or failure of Lender at any time to
demand strict adherence to the terms of this Note shall be deemed to constitute
a course of conduct inconsistent with Lender's right at any time, before or
after any Event of Default, to demand strict adherence to the terms of this
Note.

         This Note may be prepaid, in full or in part, at any time, but only
upon the simultaneous payment of the following prepayment fees:

         (a)      at any time on or after the date hereof but prior to December
                  20, 1998, the prepayment fee shall be Seventy Thousand
                  ($70,000.00) Dollars;

         (b)      at any time on or after December 20, 1998 but prior to January
                  20, 1999, the prepayment fee shall be Fifty Eight Thousand
                  Three Hundred Thirty Three and 33/100 ($58,333.33) Dollars;

         (c)      at any time on or after January 20, 1999 but prior to February
                  20, 1999, the prepayment fee shall be Forty Six Thousand Six
                  Hundred Sixty Six and 66/100 ($46,666.66) Dollars; and

         (d)      At any time on or after February 20, 1999 there shall be no
                  prepayment fee.

         Nothing herein contained, nor any transaction relating thereto, or
hereto, shall be construed or so operate as to require the Borrower to pay, or
be charged, interest at a greater rate than the maximum allowed by the
applicable law relating to this Note. Should any interest or other charges,
charged, paid or payable by the Borrower in connection with this Note, or any
other document delivered in connection herewith, result in the charging,
compensation, payment or earning of interest in excess of the maximum allowed by
the applicable law as aforesaid, then any and all such excess shall be and the
same is hereby waived by the holder, and any and all such excess paid shall be
automatically credited against and in reduction of the principal due under this
Note. If Lender shall reasonably determine that the Effective Interest Rate
(together with all other charges or payments related hereto that may be deemed
interest) stipulated under this Note is, or may be, usurious or otherwise
limited by law, the unpaid balance of this Note, with accrued interest at the
highest rate then permitted to be charged by stipulation in writing between
Lender and Borrower, at the option of Lender, shall immediately become due and
payable.

         Upon the occurrence of a Default as set forth in the Loan Agreement,
the entire unpaid principal balance and all accrued interest shall, at the sole
discretion of Lender, regardless of the Due Date, be immediately due and
payable, together with (to the extent permitted under applicable law) the costs,
reasonable attorney's fees, and reasonable outside consultants' fees incurred by
Lender in collecting or enforcing payment. During any period of a Default as
defined in the Loan Agreement, the outstanding principal amount hereof shall
bear interest at a rate which is equal to eight (8%) percent per annum greater
than the Effective Interest Rate otherwise charged hereunder. If any required
installment is not paid when due, then, at the option of Lender, in addition to
all other sums due hereunder, a late charge of five cents ($.05) for each dollar
of the installment so overdue may be charged to cover the extra expense and
other costs incurred in connection with delinquent payments and not as
additional interest or a penalty, it being understood and agreed that Lender
shall incur additional costs as a result of any late payment, the precise amount
of which may be difficult to ascertain.

         Borrower hereby grants to Lender a security interest in any
indebtedness or liability of Lender to Borrower, however evidenced, including a
security interest in all of Borrower's deposits, instruments, negotiable
documents and chattel paper which at any time are in the possession or control
of Lender, as further security for repayment of the Indebtedness of Borrower;
and Borrower hereby grants to Lender all rights and privileges afforded a
secured party under the Michigan Uniform Commercial Code with respect to any
such indebtedness or liability in which lender is hereby granted a security
interest.

         All payments hereunder shall, at option of Lender, first be applied
against accrued interest, and the balance against principal. Acceptance by
Lender of any payment in an amount less than the amount then due shall be deemed
an acceptance on account only, and the failure to pay the entire amount then due
shall be and continue to be an event of default, and at any time thereafter and
until the entire amount then due has been paid, Lender shall be entitled to
exercise all rights conferred upon it by this Note upon occurrence of default as
herein set forth.

hereto.

         This Note is secured by, and executed pursuant to, a Loan Agreement and
a Security Agreement each of even date herewith between Borrower and Lender, as
the same may be amended, modified or altered from time to time (herein referred
to as the "Loan Documents") and the Collateral, the Premises and Collateral
