                             STANDARD FEDERAL BANK

                                PROMISSORY NOTE

                               (Line of Credit)                [X]   Renewal

$11,000,000.00                                     Troy           , Michigan
------------------------------------------------  ----------------

Due Date: March 1, 1998                           Dated: July 17, 1996
------------------------------------------------        ----------------


     FOR VALUE RECEIVED, on the Due Date unless accelerated earlier as provided
herein, the undersigned, jointly and severally (collectively, "Borrower"),
promise to pay to the order of Standard Federal Bank, a federal savings bank
("Standard Federal"), at its office set forth below, or at such other place as
Standard Federal may designate in writing, the principal sum of Eleven Million
and 00/100 Dollars ($11,000,000.00) or such lesser amount as may from time to
time be outstanding by reason of having been advanced hereunder, plus interest
as hereinafter provided on all amounts from time to time outstanding hereunder,
all in lawful money of the United States of America.

     The principal outstanding under this Note from time to time shall bear
interest ("Effective Interest Rate"), on a basis of a year of 360 days for the
actual number of days amounts are outstanding hereunder, at a rate per annum
equal to the Wall Street Journal Prime Rate.  As used herein the phrase "Wall
Street Journal Prime Rate" shall mean the "Prime Rate" published by the Wall
Street Journal as the base rate on corporate loans posted by at least 75% of
the nation's 30 largest banks as the same may be changed from time to time.  If
more than one Prime Rate is published, the highest rate published shall be
deemed the Wall Street Journal Prime Rate.  If the publishing of the Wall
Street Journal Prime Rate is discontinued during the term hereof, then the
Effective Interest Rate shall be based upon the index which is published by The
Wall Street Journal in replacement thereof based on similar base rates on
corporate loans or, if no such replacement index is published, the index which,
in Standard Federal's sole determination, most nearly corresponds to the Wall
Street Journal Prime Rate.  If, in such event, Standard Federal selects an
index which, in the Borrower's opinion, does not correspond to the Wall Street
Journal Prime Rate, Borrower's sole remedy shall be to prepay this Note in full
without penalty or premium.  Until such prepayment has been received by
Standard Federal, the index selected by Standard Federal shall apply for all
purposes of this Note.

     It is understood and agreed by Borrower that the Effective Interest Rate
shall be determined by reference to the "Wall Street Journal Prime Rate" and
not by reference to the actual rate of interest charged by any particular bank
to any particular borrower

or borrowers and shall automatically increase or decrease when and to
the extent that the Wall Street Journal Prime Rate shall have been increased or
decreased.

     Accrued interest shall be payable on the first day of each month beginning
on August 1, 1996.

     This Note is given as evidence of any and all indebtedness of the Borrower
to Standard Federal arising as a result of advances or other credit which may
be made under this Note from time to time in accordance with the provisions of
an Amended and Restated Loan Agreement of even date herewith, by and between
Standard Federal and the Borrower (the "Loan Agreement"). Any and all
indebtedness may be repaid by the Borrower in whole or in part from time to
time prior to the Due Date.  Standard Federal shall, from time to time prior to
the Due Date, make advances to Borrower hereunder upon request therefor by
Borrower, provided that, upon giving effect to such advance: (a) no Event of
Default (as hereinafter defined) and no event which with notice and/or the
passage of time would become an Event of Default shall exist at the time the
advance is to be made; (b) all representations and warranties of Borrower
theretofore made are true and correct; (c) Standard Federal shall not have
previously or concurrently declared all amounts owing hereunder to be
immediately due and payable; (d) the amount requested shall not cause the total
amount outstanding hereunder to exceed the Credit Limit, as defined in the Loan
Agreement; and (e) all other requirements for the making of advances provided
for in the Loan Agreement have been satisfied.  The principal amount of
indebtedness owing pursuant to this Note shall change from time to time,
decreasing in an amount equal to any and all payments of principal made by the
Borrower and increasing by an amount equal to any and all advances made by
Standard Federal to the Borrower pursuant to the terms hereof, and the books
and records of Standard Federal shall be conclusive evidence of the amount of
principal and interest owing hereunder at any time.  All payments made
hereunder shall be applied first against costs and expenses required to be paid
hereunder, then against accrued interest to the extent thereof and the balance
shall be applied against the outstanding principal amount hereof.

     Nothing herein contained, nor any transaction relating thereto, or hereto,
shall be construed or so operate as to require the Borrower to pay, or charge,
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 applicable law, then
any and all such excess shall be and the same is hereby waived by Standard
Federal, and any and all such excess paid shall be automatically credited
against and in reduction of the principal due under this Note.  If Standard

Federal 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
permitted to be charged by stipulation in writing between Standard Federal and
Borrower, at the option of Standard Federal, shall immediately become due and
payable.

     The Borrower represents and warrants that it is duly organized, validly
existing and in good standing and is duly authorized to make and perform this
Note, which constitutes its valid and binding legal obligation enforceable in
accordance with its terms.  All financial data furnished to Standard Federal in
connection with this Note fairly present the financial condition of the
Borrower and its subsidiaries, if any, as of the dates thereof and there has
been no material adverse change in the condition (financial or otherwise) of
the Borrower since such dates.

     An Event of Default shall be deemed to have occurred hereunder if any
indebtedness of the Borrower to Standard Federal hereunder is not paid when
due, regardless of whether such indebtedness has arisen pursuant to the terms
of this Note, the Loan Agreement or any mortgage, security agreement, guaranty,
instrument or other agreement executed in conjunction herewith, or if an Event
of Default shall otherwise occur under the Loan Agreement.

     Upon the occurrence of any Event of Default, after the giving of any
notice and the expiration of any grace, cure or notice period provided for in
the Loan Agreement, if any, and if no such notice or grace, cure or notice
period is so provided for in the Loan Agreement, then immediately, Standard
Federal may declare the entire unpaid and outstanding principal balance
hereunder and all accrued interest to be due and payable in full forthwith,
without presentment, demand or notice of any kind and may exercise any one or
more of the rights and remedies provided herein or in the Loan Agreement or in
any mortgage, guaranty, security agreement or other document relating hereto or
by applicable law.  The remedies provided for hereunder are cumulative to the
remedies for collection of the amounts owing hereunder as provided by law or by
the Loan Agreement, or by any   mortgage, guaranty, security agreement or other
document relating hereto. Nothing herein is intended, nor should it be
construed, to preclude Standard Federal from pursuing any other remedy for the
recovery of any other sum to which Standard Federal may be or become entitled
for breach of the terms of this Note or the Loan Agreement, or any mortgage,
guaranty, security agreement or other instrument relating hereto.

     Borrower agrees, in case of an Event of Default under the terms of this
Note or under any loan agreement, security or other agreement executed in
connection herewith, to pay all costs of Standard Federal for collection of the
Note and all other 


                                     -3-

liabilities of Borrower to Standard Federal and enforcement of rights
hereunder, including reasonable attorney fees and legal expenses        
including participation in Bankruptcy proceedings.  During any period(s) this
Note is in default, or after the Due Date, or after acceleration of maturity,
the outstanding principal amount hereof shall bear interest at a rate equal to
two percent (2.0%) per annum greater than the interest rate otherwise charged
hereunder.  If any required payment is not made within ten (10) days after the
date it is due, then, at the option of Standard Federal, a late charge of not
more than four cents ($.04) for each dollar of the payment so overdue may be
charged.  In addition to any other security interests granted to Standard
Federal, Borrower hereby grants Standard Federal a security interest in all of
Borrower's bank deposits, instruments, negotiable documents, and chattel paper
which at any time are in the possession or control of Standard Federal.  After
the occurrence of an Event of Default hereunder, Standard Federal may hold and
apply at any time its own indebtedness or liability to Borrower in payment of
any indebtedness hereunder.

     Acceptance by Standard Federal 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.  Upon any Event of Default, neither the failure of Standard Federal
promptly to exercise its right to declare the outstanding principal and accrued
unpaid interest hereunder to be immediately due and payable, nor the failure of
Standard Federal to demand strict performance of any other obligation of the
Borrower or any other person who may be liable hereunder shall constitute a
waiver of any such rights, nor a waiver of such rights in connection with any
future default on the part of the Borrower or any other person who may be
liable hereunder.

     Borrower and all endorsers and guarantors hereof, hereby jointly and
severally waive presentment for payment, demand, notice of non-payment, notice
of protest or protest of this Note, diligence in collection or bringing suit,
and hereby consent to any and all extensions of time, renewals, waivers, or
modifications that may be granted by Standard Federal with respect to
payment or any other provisions of this Note, and to the release of any
collateral or any part thereof, with or without substitution.  The liability of
the Borrower shall be absolute and unconditional, without regard to the
liability of any other party hereto.

     This Note is executed pursuant to the Loan Agreement and is secured by a
Security Agreement, dated September 15, 1994, and by a Security Agreement,
dated July 19, 1995, and by an Assignment of Policy as Collateral Security, of
even date herewith.  Reference is hereby made to such documents for additional
terms relating to the transaction giving rise to this Note, the security given
for this 


                                     -4-

Note and additional terms and conditions under which this Note matures, may be
accelerated or prepaid.

     Advances hereunder may be requested by telephone, in writing or in any
other manner acceptable to Standard Federal.  Borrower understands and agrees
that any telephone conversation with Standard Federal may be recorded for
accuracy.
