                                                 DEMAND
--------------------------------------------------------------------------------

For Value Received, the undersigned promise(s) to pay on the earlier to occur of
, 1999 and DEMAND to the order of Comerica Bank  ("Bank"),  at any office of the
Bank in the State of  Michigan,  Eight  Million Five  Hundred  Thousand  Dollars
(U.S.)  (or that  portion  of it  advanced  by the Bank and not  repaid as later
provided) with interest until demand or until  Default,  as later defined,  at a
per annum rate equal to the Bank's prime rate from time to time in effect plus 1
% per annum and after  that at a rate  equal to the rate of  interest  otherwise
prevailing  under  this Note plus 3% per annum (but in no event in excess of the
maximum rate  permitted by law).  The Bank's "prime rate" is that annual rate of
interest so designated by the Bank and which is changed by the Bank from time to
time. Interest rate changes will be effective for interest  computation purposes
as and when the Bank's prime rate changes.  Interest  shall be calculated on the
basis  of a  360-day  year  for the  actual  number  of days  the  principal  is
outstanding.  Unless  sooner  demanded,  accrued  interest on this Note shall be
payable on the first day of each month commencing
       August 1, 1999 . If the  frequency of interest  payments is not otherwise
specified,  accrued  interest on this Note shall be payable monthly on the first
day of each  month,  unless  sooner  demanded.  If any payment of  principal  or
interest under this Note shall be payable on a day other than a day on which the
Bank is open for business, this payment shall be extended to the next succeeding
business  day and interest  shall be payable at the rate  specified in this Note
during this  extension.  A late payment  charge equal to 5% of each late payment
may be charged on any payment not  received by the Bank within 10 calendar  days
after the payment due date,  but  acceptance of payment of this charge shall not
waive any Default under this Note.

The  principal  amount  payable under this Note shall be the sum of all advances
made  by the  Bank  to or at the  request  of the  undersigned,  less  principal
payments  actually  received  in cash by the Bank.  The books and records of the
Bank shall be the best evidence of the principal  amount and the unpaid interest
amount owing at any time under this Note and shall be conclusive absent manifest
error.  No  interest  shall  accrue  under this Note until the date of the first
advance made by the Bank;  after that interest on all advances  shall accrue and
be computed on the principal  balance  outstanding  from time to time under this
Note  until  the same is paid in full.  At no time  shall  the Bank be under any
obligation  to make  any  advances  to the  undersigned  pursuant  to this  Note
(notwithstanding  anything expressed or implied in this Note or elsewhere to the
contrary,  including  without limit if the Bank supplies the undersigned  with a
borrowing  formula)  and the Bank,  at any time and from  time to time,  without
notice,  and  in its  sole  discretion,  may  refuse  to  make  advances  to the
undersigned  without  incurring  any  liability  due to this refusal and without
affecting the  undersigned's  liability  under this Note for any and all amounts
advanced.

This  Note  and  any  other  indebtedness  and  liabilities  of any  kind of the
undersigned  (or any of  them)  to the  Bank,  and  any  and all  modifications,
renewals or extensions of it, whether joint or several,  contingent or absolute,
now   existing   or  later   arising,   and  however   evidenced   (collectively
"Indebtedness")  are  secured by and the Bank is granted a security  interest in
all items deposited in any account of any of the  undersigned  with the Bank and
by all proceeds of these items (cash or otherwise),  all account balances of any
of the  undersigned  from time to time with the Bank,  by all property of any of
the undersigned from time to time in the possession of the Bank and by any other
collateral,  rights and  properties  described  in each and every deed of trust,
mortgage,   security  agreement,   pledge,  assignment  and  other  security  or
collateral  agreement  which has been, or will at any time(s) later be, executed
by any  (or  all)  of  the  undersigned  to or  for  the  benefit  of  the  Bank
(collectively  "Collateral").  Notwithstanding the above, (i) to the extent that
any portion of the  Indebtedness  is a consumer loan,  that portion shall not be
secured by any deed of trust or mortgage on or other security interest in any of
the  undersigned's  principal  dwelling  or in  any of  the  undersigned's  real
property  which is not a purchase  money  security  interest as to that portion,
unless  expressly  provided  to the  contrary in another  place,  or (ii) if the
undersigned  (or any of them) has(have) given or give(s) Bank a deed of trust or
mortgage covering California real property, that deed of trust or mortgage shall
not secure this Note or any other  indebtedness  of the  undersigned  (or any of
them), unless expressly provided to the contrary in another place.

If the  undersigned (or any of them) or any guarantor under a guaranty of all or
part  of  the  Indebtedness   ("guarantor")  (i)  fail(s)  to  pay  any  of  the
Indebtedness when due, by maturity, acceleration or otherwise, or fail(s) to pay
any Indebtedness  owing on a demand basis upon demand; or (ii) fail(s) to comply
with any of the terms or provisions of any agreement between the undersigned (or
any of them) or any such guarantor and the Bank; or (iii) become(s) insolvent or
the  subject of a  voluntary  or  involuntary  proceeding  in  bankruptcy,  or a
reorganization,  arrangement or creditor composition proceeding,  (if a business
entity) cease(s) doing business as a going concern, (if a natural person) die(s)
or become(s) incompetent,  (if a partnership) dissolve(s) or any general partner
of  it  dies,  becomes  incompetent  or  becomes  the  subject  of a  bankruptcy
proceeding or (if a corporation or a limited  liability  company) is the subject
of  a  dissolution,   merger  or  consolidation;  or  (a)  if  any  warranty  or
representation  made by any of the  undersigned  or any  guarantor in connection
with this Note or any of the  Indebtedness  shall be  discovered to be untrue or
incomplete; or (b) if there is any termination, notice of termination, or breach
of any  guaranty,  pledge,  collateral  assignment  or  subordination  agreement
relating to all or any part of the Indebtedness;  or (c) if there is any failure
by  any  of the  undersigned  or  any  guarantor  to  pay  when  due  any of its
indebtedness (other than to the Bank) or in the observance or performance of any
term, covenant or condition in any document evidencing,  securing or relating to
such  indebtedness;  or (d) if the Bank deems itself insecure believing that the
prospect of payment of this Note or any of the Indebtedness is impaired or shall
fear deterioration,  removal or waste of any of the Collateral;  or (e) if there
is filed or issued a levy or writ of  attachment  or  garnishment  or other like
judicial  process upon the  undersigned (or any of them) or any guarantor or any
of the Collateral,  including without limit, any accounts of the undersigned (or
any of them) or any guarantor with the Bank,  then the Bank, upon the occurrence
of any of these events (each a  "Default"),  may at its option and without prior
notice  to  the  undersigned  (or  any  of  them),  declare  any  or  all of the
Indebtedness to be immediately due and payable  (notwithstanding  any provisions
contained in the evidence of it to the  contrary),  sell or liquidate all or any
portion of the Collateral, set off against the Indebtedness any amounts owing by
the Bank to the  undersigned  (or any of them),  charge  interest at the default
rate provided in the document evidencing the relevant  Indebtedness and exercise
any one or more of the rights and remedies  granted to the Bank by any agreement
with the undersigned (or any of them) or given to it under applicable law.



<PAGE>


The undersigned  acknowledge(s)  that this Note matures upon issuance,  and that
the Bank, at any time,  without notice, and without reason, may demand that this
Note be  immediately  paid in full.  The demand nature of this Note shall not be
deemed  modified by reference to a Default in this Note or in any agreement to a
default  by  the  undersigned  or to  the  occurrence  of an  event  of  default
(collectively  an "Event of Default").  For purposes of this Note, to the extent
there is reference  to an Event of Default this  reference is for the purpose of
permitting  the Bank to  accelerate  Indebtedness  not on a demand  basis and to
receive  interest at the default rate  provided in the document  evidencing  the
relevant  Indebtedness.  It is  expressly  agreed that the Bank may exercise its
demand  rights under this Note whether or not an Event of Default has  occurred.
The Bank, with or without reason and without notice,  may from time to time make
demand for partial payments under this Note and these demands shall not preclude
the Bank from demanding at any time that this Note be immediately  paid in full.
All payments  under this Note shall be in  immediately  available  United States
funds, without setoff or counterclaim.

If this Note is signed by two or more  parties  (whether  by all as makers or by
one or more  as an  accommodation  party  or  otherwise),  the  obligations  and
undertakings  under this Note  shall be that of all and any two or more  jointly
and also of each  severally.  This  Note  shall  bind the  undersigned,  and the
undersigned's  respective  heirs,  personal   representatives,   successors  and
assigns.  The  undersigned  waive(s)  presentment,  demand,  protest,  notice of
dishonor, notice of demand or intent to demand, notice of acceleration or intent
to  accelerate,  and  all  other  notices  and  agree(s)  that no  extension  or
indulgence  to the  undersigned  (or any of them) or  release,  substitution  or
nonenforcement  of  any  security,  or  release  or  substitution  of any of the
undersigned,  any guarantor or any other party,  whether with or without notice,
shall affect the obligations of any of the undersigned. The undersigned waive(s)
all defenses or right to discharge available under Section 3-605 of the Michigan
Uniform  Commercial Code and waive(s) all other suretyship  defenses or right to
discharge. The undersigned agree(s) that the Bank has the right to sell, assign,
or grant participations or any interest in, any or all of the Indebtedness,  and
that, in connection  with this right,  but without  limiting its ability to make
other  disclosures  to the full  extent  allowable,  the Bank may  disclose  all
documents  and  information  which  the Bank now or later  has  relating  to the
undersigned  or the  Indebtedness.  The  undersigned  agree(s) that the Bank may
provide information  relating to this Note or relating to the undersigned to the
Bank's parent, affiliates, subsidiaries and service providers.

The  undersigned  agree(s)  to  reimburse  the holder or owner of this Note upon
demand for any and all costs and expenses (including without limit, court costs,
legal expenses and reasonable  attorney fees,  whether inside or outside counsel
is used,  whether or not suit is instituted and, if suit is instituted,  whether
at  the  trial  court  level,  appellate  level,  in a  bankruptcy,  probate  or
administrative  proceeding or otherwise) incurred in collecting or attempting to
collect this Note or incurred in any other matter or proceeding relating to this
Note.

The  undersigned   acknowledge(s)  and  agree(s)  that  there  are  no  contrary
agreements, oral or written,  establishing a term of this Note and agree(s) that
the terms and  conditions  of this Note may not be  amended,  waived or modified
except in a writing signed by an officer of the Bank expressly  stating that the
writing  constitutes an amendment,  waiver or  modification of the terms of this
Note.  As used in this Note,  the word  "undersigned"  means,  individually  and
collectively,  each maker, accommodation party, indorser and other party signing
this Note in a similar capacity.  If any provision of this Note is unenforceable
in whole or part for any reason,  the remaining  provisions shall continue to be
effective.  THIS NOTE IS MADE IN THE STATE OF MICHIGAN  AND SHALL BE GOVERNED BY
AND  CONSTRUED IN  ACCORDANCE  WITH THE INTERNAL  LAWS OF THE STATE OF MICHIGAN,
WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.
<PAGE>

THE  MAXIMUM  INTEREST  RATE  SHALL NOT EXCEED  25% PER  ANNUM,  OR THE  HIGHEST
APPLICABLE USURY CEILING, WHICHEVER IS LESS.

THE  UNDERSIGNED AND THE BANK  ACKNOWLEDGE  THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL  ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR
HAVING HAD THE  OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE,  KNOWINGLY
AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO TRIAL BY JURY
IN THE EVENT OF LITIGATION  REGARDING THE  PERFORMANCE OR ENFORCEMENT  OF, OR IN
ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS.
