                        DEMAND NOTE
                              
     
     Executed as of the 25   day of       February     , 19   97     at
     Chicago, Illinois.        No.      1407980100  
     
     
     Amount $3,500,000.00
     
     
          FOR VALUE RECEIVED, the Undersigned (jointly and
     severally, if more than one) promises to pay to the order of LASALLE
     NATIONAL BANK (hereinafter, together with any holder hereof, called
     "Bank"), at the main office of the Bank, the principal sum of    Three
     Million five Hundred  and No/100    Dollars ($3,500,000.00------) plus
     the aggregate unpaid principal amount of all advances made by Bank to
     the Undersigned (or any one of them, if more than one) pursuant to and
     in accordance with Paragraph 2 of the Loan Agreement (as hereinafter
     defined) in excess of such amount, or, if less, the aggregate unpaid
     principal amount of all advances made by Bank to the Undersigned (or
     any one of them, if more than one) pursuant to and in accordance with
     Paragraph 2 of the Loan Agreement.  The Undersigned (jointly and
     severally, if more than one) further promises to pay interest on the
     outstanding principal amount hereof on the dates and at the rates
     provided in the Loan Agreement from the date hereof until payment in
     full hereof.
     
          This Demand Note is referred to in and was delivered
     pursuant to that certain Loan and Security Agreement, as it may be
     amended from time to time, together  with all exhibits thereto,  dated
         February 25 , 19,   97   between Bank and the Undersigned (the
     "Loan Agreement").  All terms which are capitalized and used herein
     (which are not otherwise defined herein) shall have the meaning
     ascribed to such term in the Loan Agreement.
     
          THE OUTSTANDING PRINCIPAL BALANCE OF THE UNDERSIGNED'S
     LIABILITIES TO BANK UNDER THIS DEMAND NOTE SHALL BE PAYABLE UPON
     DEMAND.  Prior to demand, principal hereunder shall be payable
     pursuant to the terms of the Loan Agreement.
     
          The Undersigned (and each one of them, if more than one)
     hereby authorizes the Bank to charge any account of the Undersigned
     (and each one of them, if more than one) for all sums due hereunder. 
     If payment hereunder becomes due and payable on a Saturday, Sunday or
     legal holiday under the laws of the United States or the State of
     Illinois, the due date thereof shall be extended to the next
     succeeding business day, and interest shall be payable thereon at the
     rate specified during such extension.  Credit shall be given for
     payments made in the manner and at the times provided in the Loan
     Agreement.  It is the intent of the parties that the rate of interest
     and other charges to the Undersigned under this Demand Note shall be
     lawful; therefore, if for any reason the interest or other charges
     payable hereunder are found by a court of competent jurisdiction, in
     a final determination, to exceed the limit which Bank may lawfully
     charge the Undersigned, then the obligation to pay interest or other
     charges shall automatically be reduced to such limit and, if any
     amount in excess of such limit shall have been paid, then such amount
     shall be refunded to the Undersigned.
     
          The principal and all accrued interest hereunder may be
     prepaid by the Undersigned, in part or in full, at any time; provided,
     however, that if the Undersigned prepays all of the Liabilities prior
     to the end of the Original Term or any Renewal Term, the Undersigned
     shall pay a prepayment fee as provided in the Loan Agreement.
     
          The Undersigned (and each one of them, if more than one)
     waives the benefit of any law that would otherwise restrict or limit
     Bank in the exercise of its right, which is hereby acknowledged, to
     set-off against the Liabilities, without notice and at any time
     hereafter, any indebtedness matured or unmatured owing from Bank to
     the Undersigned (or any one of them).  The Undersigned (and each one
     of them, if more than one) waives every defense, counterclaim or
     setoff which the Undersigned (or any one of them) may now have or
     hereafter may have to any action by Bank in enforcing this Note and/or
     any of the other Liabilities, or in enforcing Bank's rights in the
     Collateral and ratifies and confirms whatever Bank may do pursuant to
     the terms hereof and of the Loan Agreement and with respect to the
     Collateral and agrees that Bank shall not be liable for any error in
     judgment or mistakes of fact or law, except for acts of gross
     negligenceor wilful misconduct.
     
          The Undersigned, any other party liable with respect to
     the Liabilities and any and all endorsers and accommodation parties,
     and each one of them, if more than one, waive any and all presentment,
     demand, notice of dishonor, protest, and all other notices and demands
     in connection with the enforcement of Bank's rights hereunder.
     
          The loan evidenced hereby has been made and this Note has
     been delivered at Chicago, Illinois.  THIS NOTE SHALL BE GOVERNED AND
     CONTROLLED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS AS TO
     INTERPRETATION, ENFORCEMENT, VALIDITY, CONSTRUCTION, EFFECT, AND IN
     ALL OTHER RESPECTS, INCLUDING WITHOUT LIMITATION, THE LEGALITY OF THE
     INTEREST RATE AND OTHER CHARGES, and shall be binding upon the
     Undersigned (and each one of them, if more than one) and the
     Undersigned's heirs, legal representatives, successors and assigns
     (and each of them, if more than one).  If this Note contains any
     blanks when executed by the Undersigned (or any one of them, if more
     than one), the Bank is hereby authorized, without notice to the
     Undersigned (or any one of them, if more than one) to complete any
     such blanks according to the terms upon which the loan or loans were
     granted.  Wherever possible, each provision of this Note shall be
     interpreted in such manner as to be effective and valid under
     applicable law, but if any provision of this Note shall be prohibited
     by or be invalid under such law, such provision shall be severable,
     and be ineffective to the extent of such prohibition or invalidity,
     without invalidating the remaining provisions of this Note.  If more
     than one party shall execute this Note, the term "Undersigned" as used
     herein shall mean all parties signing this Note, and each one of them,
     and all such parties, their respective heirs, executors,
     administrators, successors and assigns, shall be jointly and severally
     obligated hereunder.
     
          To induce the Bank to make the loan evidenced by this
     Note, the Undersigned (and each one of them, if more than one) (i)
     irrevocably agrees that, subject to Bank's sole and absolute election,
     all actions arising directly or indirectly as a result or in
     consequence of this Note or any other agreement with the Bank, or the
     Collateral, shall be instituted and litigated only in courts having
     situs in the City of Chicago, Illinois, (ii) hereby consents to the
     exclusive jurisdiction and venue of any State or Federal Court located
     and having its situs in said city, and (iii) waives any objection
     based on forum non-conveniens.  IN ADDITION, BANK AND THE UNDERSIGNED
     (OR ANY ONE OF THEM, IF MORE THAN ONE) HEREBY WAIVE TRIAL BY JURY IN
     ANY ACTION OR PROCEEDING WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS
     NOTE, THE LIABILITIES, THE COLLATERAL, ANY ALLEGED TORTIOUS CONDUCT BY
     THE UNDERSIGNED OR BANK.  In addition, the Undersigned agrees  that
     all service of process may be made as provided in the Loan Agreement.
     
          As used herein, all provisions shall include the
     masculine, feminine, neuter, singular and plural thereof, wherever the
     context and facts require such construction and in particular the word
     "Undersigned" shall be so construed.
     
          IN WITNESS WHEREOF, each of the Undersigned, if more than
     one, has executed this Note on the date above set forth.
