- ------------------------------------- ------------------------------------------



     Accrued interest on the outstanding principal balance of this Note shall be
payable on a monthly basis with each principal payment.

     The  payment of all  amounts  due under this Note is secured by a letter of
credit  of even date in the  amount of Six  Hundred  Eighty-Five  Thousand  Nine
Hundred Twelve and Fifty-Seven  One-Hundredths  ($685,912.57)  Dollars issued by
Security State Bank for the benefit of the Payee.

     In the event the Maker  shall (a) fail to make any payment  hereunder  when
due; (b) admit in writing its  inability  to pay its debts as they  mature;  (c)
make a general  assignment  for the benefit of creditors;  (d) be  adjudicated a
bankrupt or insolvent; (e) file a voluntary petition in bankruptcy or a petition
or an answer seeking an arrangement  with  creditors;  (f) take advantage of any
bankruptcy,  insolvency or readjustment of debt law or statute or file an answer
admitting  the  material  allegations  of a  petition  filed  against  it in any
proceeding  under any such law;  or (g) have  entered  against it a court  order
approving a petition filed against it under the Federal Bankruptcy Act, then and
in each and every such event (an "Event of Default"),  the Payee may, by written
notice to the Maker,  declare the entire  unpaid  principal  amount of this Note
then outstanding plus accrued interest to be forthwith due and payable whereupon
the same shall become forthwith due and payable.

     The Maker may prepay  the  principal  amount of this  Note,  in whole or in
part,  from time to time,  without  premium or penalty,  provided that the Maker
pays all interest  accrued with regard to the  principal  prepaid to the date of
prepayment.  All  prepayments  shall be applied in the inverse  order of the due
dates under this Note.

     If the  Maker  shall  fail to pay when  due,  whether  by  acceleration  or
otherwise,  all or any portion of the principal  amount hereof,  any such unpaid
amount  shall bear  interest for each day from the date it was so due until paid
in full at the rate of two percent  (2%) above the prime rate as  reported  from
time to time in The Wall Street Journal, payable on demand.

     Notwithstanding  anything to the contrary  contained in this Note, the rate
of interest payable on this Note shall never exceed the maximum rate of interest
permitted under applicable law.

     This Note may not be waived,  changed,  modified or discharged  orally, but
only by an agreement in writing, signed by the party against whom enforcement of
any waiver, change, modification or discharge is sought.

     Should the  indebtedness  represented  by this Note or any part  thereof be
collected at law or in equity, or in bankruptcy, receivership or any other court
proceedings  (whether at the trial or appellate  level),  or should this Note be
placed in the hands of any agent or  attorneys  for  collection  upon default or
maturity,  the Maker  agrees to pay, in  addition  to all other  amounts due and
payable hereunder, all reasonable costs and expenses of collection or attempting
to collect this Note, including reasonable attorneys' fees.

     The Maker and any endorsers  hereof,  for themselves  and their  respective
representatives,



                                       2




successors  and assigns,  expressly (a) waive  presentment,  protest,  notice of
dishonor,  notice  of  non-payment,  notice  of  maturity,  notice  of  protest,
diligence  in  collection,   and  the  benefit  of  any  applicable  exemptions,
including, but not limited to, exemptions claimed under insolvency laws, and (b)
consent  that the Payee may release or  surrender,  exchange or  substitute  any
property or other collateral or security now held or which may hereafter be held
as  security  for the payment of this Note,  and/or may  release any  guarantor,
and/or may  extend the time for  payment  and/or  otherwise  modify the terms of
payment of any part or the whole of the debt evidenced hereby.

     Any notice, demand or request relating to any matter set forth herein shall
be in writing and shall be deemed  effective when hand  delivered,  when mailed,
postage prepaid,  by registered or certified mail, return receipt requested,  or
by a nationally  recognized  overnight mail or courier service,  or when sent by
facsimile transmission to the Maker or the Payee at its address stated herein or
at such other  address of which it shall have  notified  the party  giving  such
notice in writing as aforesaid.

     The Payee  shall be  entitled  to assign  all or any  portion of its right,
title and interest in and to this Note at is sole  discretion  without notice to
the Maker,  provided  that the Maker shall  continue to make  payments  required
hereunder  to the  Payee  until it has  received  notice  of change of payee for
payments as provided herein.

     Notwithstanding  any  other  provision  of this  Note,  all  payments  made
hereunder shall be applied first to payment of sums payable hereunder other than
interest and principal,  secondly, interest on the principal balance outstanding
hereunder from time to time, and thirdly to principal.

     The Maker  acknowledges and agrees that the obligations under this Note are
unconditional  and are not  subject to any  defense,  counterclaim,  or right of
offset or setoff;  provided,  however,  that,  in the event that (a) no Event of
Default shall have occurred, and (b) the Maker shall have duly exercised its put
option  in  accordance  with the  terms  and  conditions  of the  Inventory  Put
Agreement  of even date  between the Maker and the Payee (the "Put  Agreement"),
then the Maker shall have the right,  by written notice to the Payee, to offset,
against  the final  payment(s)  due under  this Note,  the  amount  then due and
payable by the Payee to the Maker  pursuant  to the Put  Agreement.  In no event
shall the Maker have the right to offset more than the Final  Principal  Payment
Amount.

     This Note shall be governed by, and construed in accordance  with, the laws
of the State of Ohio, excluding conflict of law principles thereof.

     The  Maker  acknowledges  that  it  has  been  represented  by  counsel  in
connection  with this Note.  Accordingly,  any rule or law or any legal decision
that would require the  interpretation  of any claimed  ambiguities in this Note
against the party that drafted it has no application and is expressly  waived by
the Maker.  The  provisions  of this Note shall be  interpreted  in a reasonable
manner to give effect to the intent of the Maker and the Payee.

of any and all  disputes  that may be filed in any court and that  relate to the
subject matter of this Note,  including,  without  limitation,  contract claims,
tort  claims,  breach of duty  claims,  and all other  statutory  and common law
claims.  THIS  WAIVER  SHALL  APPLY  TO  ANY  SUBSEQUENT  AMENDMENTS,  RENEWALS,
SUPPLEMENTS  OR  MODIFICATIONS  OF THIS NOTE. In the event of  litigation,  this
provision may be filed as a written consent to a trial by the court.

Warrant of Attorney
- --------------------

in any Court of Record in the State of Ohio or in any other  state or  territory
of the  United  States of  America  after the above  indebtedness  becomes  due,
whether by  acceleration  or  otherwise,  to waive the  issuance  and service of
process, and to confess joint and several judgment against the Maker in favor of
the Payee for the amount then  appearing  due together  with costs of suit,  and
thereupon  to waive all errors and all rights of appeal and stays of  execution.

such  judgment  be vacated  for any reason,  the  foregoing  warrant of attorney
nevertheless may thereafter be utilized for obtaining judgment or judgments.
