================================================================================


On the Maturity  Date,  as stated above,  for value  received,  the  undersigned
promise(s) to pay to the order of Comerica Bank  ("Bank"),  at any office of the
Bank in the State of Michigan,  Six Million Five Hundred Thousand Dollars (U.S.)
($6,500,000) (or that portion of it advanced by the Bank and not repaid as later
provided) with interest until maturity, whether by acceleration or otherwise, at
a per annum  rate  equal to the  Bank's  prime rate from time to time in effect,
plus .75% until the later of the date hereof or  September 1, 1998 at which time
the rate shall be reduced to the Bank's  prime rate from time to time in effect,
and after an Event of Default (as hereafter defined) 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  for the actual  number of days the  principal is
outstanding on the basis of a 360-day year.  Accrued interest on this Note shall
be  payable  on the 1st day of each month  commencing  March 1, 1995,  until the
Maturity  Date when all  amounts  outstanding  under  this Note shall be due and
payable in full.  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.





In  consideration of the revolving  credit facility being  established  pursuant
hereto, the undersigned shall pay to the Bank a fee (the "Revolving Credit Fee")
calculated at the rate of one-quarter  percent (1/4%) per annum (based on a year
having 360 days and  calculated for the actual number of days elapsed during the
computation  period) on the  difference  between  (i) Six Million  Five  Hundred
Thousand  Dollars  ($6,500,000) and (ii) the average daily unpaid balance of the
Indebtedness  (as defined below) each calendar month (or portion thereof) during
the term of this Note. The Revolving Credit Fee shall be due on the first day of
each month commencing March 1, 1995 (for the immediately preceding month).

The  undersigned  may  terminate  this Note prior to the maturity date set forth
above upon not less than 60 days prior written notice to the Bank, provided that
the undersigned  shall pay and perform all obligations to be performed at, on or
prior to such date of termination and provided further the undersigned shall pay
to the Bank no later than such date a  termination  fee equal to the  greater of
(i) Sixteen Thousand Two Hundred Fifty Dollars  ($16,250.00) or (ii) one quarter
of one percent  (.25%) of the  maximum  principal  amount  which may be borrowed
under this Note, as the same may be amended, if terminated prior to the Maturity
Date of this Note.

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  guaranty,
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 of the  undersigned  or by any guarantor (as defined below) to or for (or
all) the benefit of the Bank (collectively "Collateral").

If the  undersigned (or any of them) or any guarantor under a guaranty of all or
part  of  the  Indebtedness   ("guarantor")  (a)  fail(s)  to  pay  any  of  the
Indebtedness within 5 days when due, by maturity,  acceleration or otherwise, or
fail(s) to pay any  Indebtedness  owing on a demand  basis upon  demand;  or (b)
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 (c)
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)  is the subject of a  dissolution,
merger or consolidation; or (d) 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 (e) if there is
any termination,


                                      -2-



notice of termination,  or breach of any guaranty, pledge, collateral assignment
or subordination  agreement relating to all or any part of the Indebtedness;  or
(f) 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,  and such  failure  gives rise to an
immediate right of acceleration of such  indebtedness;  or (g) 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"),  and  subject  to the terms of the Letter
Agreement among the parties of even date herewith, may 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. 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  accomodation  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
undersigneds' respective successors and permitted 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 3-606 of the 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) to reimburse the holder or owner of this Note 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


                                      -3-




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 WAS  EXECUTED IN CUYAHOGA  COUNTY AND SHALL BE GOVERNED BY

of Ohio.  The  undersigned  waives any claim that  Cuyahoga  County,  Ohio is an
inconvenient  forum  or an  improper  forum  based  on  lack of  venue.  Nothing
contained in this Note, however,  shall prevent Bank from bringing any action or
exercising  any rights under this Note within any other state or country  having
jurisdiction   over  the  subject  matter  hereof  The  Bank's  initiating  such
proceeding or taking such action in any other state or country shall in no event
constitute a waiver of the agreement contained in this Note that the laws of the

Bank  under  this  Note or a waiver of the  submission  made in this Note by the
undersigned to personal  jurisdiction  within the State of Ohio. The undersigned
agrees that service of process may be made, and personal  jurisdiction  over the
undersigned  obtained,  by serving a copy of the Summons and Complaint  upon the

of the State of Ohio.


                                      -4-

in favor of the Bank for the amount then appearing  due,  together with interest
and costs of suit and  thereupon  to  release  all errors and waive all right of
appear and stay of execution. No judgment against the undersigned shall be a bar
to subsequent  judgment(s)  against the  undersigned.  The foregoing  warrant of
attorney  shall  survive  any  judgment,  it being  understood  that  should any
judgment be vacated  for any  reason,  the  foregoing  warrant of  attorney  may
nevertheless be used to obtain additional judgments.

The  undersigned  has executed and delivered this Note on the day and year first
above written.
