including November 1, 1997, followed by consecutive monthly principal 
payments of $50,000 each plus accrued and unpaid interest commencing on the 
first day of December, 1997 and continuing on the first day of each month 
thereafter and ending on the Maturity Date (as hereinafter defined). The 
principal balance hereunder shall bear interest at the fixed rate of fifteen

outstanding, plus all accrued and unpaid interest thereon, shall be due and 
payable on August 31, 1998 (the "MATURITY DATE"), or such earlier date on 
which said amount shall be due and payable on account of acceleration by

principal, interest costs and expenses due hereunder shall be paid to Lender 
upon termination of the Loan Agreement referred to below.

     This Note was executed and delivered pursuant to that certain Second 
Amendment to Amended And Restated Revolving Loan and Security Agreement dated

and conditions under which the loans evidenced hereby are to be repaid and 
for a statement of remedies upon the occurrence of an "EVENT OF DEFAULT" as 
defined therein. The Loan Agreement is incorporated herein by reference in 
its entirety. All terms which are capitalized and used herein (which are not 
otherwise specifically defined herein) and which are defined in the Loan 
Agreement shall be used in this Note as defined in the Loan Agreement.

     Borrowers further promise to pay to Lender interest on the outstanding 
unpaid principal amount hereof, as provided in the Loan Agreement, from the 
date hereof until payment in full hereof as determined in accordance with the 
Loan Agreement; provided, however, that, upon the occurrence and during the 
continuance of an Event of Default, Borrowers promise to pay to Lender 
interest on the unpaid principal amount hereof at to the Default Rate 
applicable to the Liabilities evidenced by this Note as determined in 
accordance with the Loan Agreement. Interest shall be computed on the basis 
of a 360-day year for the actual number of days elapsed.



In no contingency or event whatsoever shall the rate of interest paid by 
Borrowers under this Note exceed the maximum amount permissible under any law 
which a court of competent jurisdiction shall, in a final determination, deem 
applicable hereto. In the event that such a court determines that Lender has 
received interest hereunder in excess of the maximum amount permitted by such 
law, (i) Lender shall apply such excess to any unpaid principal owed by 
Borrowers to Lender or, if the amount of such excess exceeds the unpaid 
balance of such principal, Lender shall promptly refund such excess interest 
to Borrowers and (ii) the provisions hereof shall be deemed amended to 
provide for such permissible rate. All sums paid, or agreed to be paid, by 
Borrowers which are, or hereafter may be construed to be, compensation for 
the use, forbearance or detention of money shall, to the extent permitted by 
applicable law, be amortized, prorated, spread and allocated throughout the 
full term of all such indebtedness until the indebtedness is paid in full.

     This Note is secured by (i) the Loan Agreement and certain Ancillary 
Agreements and Security Documents (as such terms are defined in the Loan 
Agreement), and (ii) all security interests, liens and encumbrances

or the Loan Agreement, and hereby consents to, and waives notice of the 
release, addition, or substitution, with or without consideration, of any 
collateral or of any person liable for payment of this Note. Any failure of 
Lender to exercise any right available hereunder or otherwise shall not be 
construed as a waiver of the right to exercise the same or as a waiver of any 
other right at any other time.

     Whenever in this Note reference is made to Lender or Borrowers, such 
reference shall be deemed to include, as applicable, a reference to their 
respective successors and assigns and, in the case of Lender, any

Loan pursuant hereto. The provisions of this Note shall be binding upon and 
shall inure to the benefit of such successors, assigns and Participants.

PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN ANY OTHER JURISDICTION 
BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW; AND (v) AGREE 
NOT TO INSTITUTE ANY LEGAL ACTION OR PROCEEDING AGAINST LENDER OR ANY OF 
LENDER'S DIRECTORS, OFFICERS, EMPLOYEES, AGENTS OR PROPERTY, CONCERNING ANY 
MATTER ARISING OUT OF OR RELATING TO THIS NOTE, THE LOAN AGREEMENT, THE 
ANCILLARY AGREEMENTS OR THE SECURITY DOCUMENTS IN ANY COURT OTHER THAN ONE 
LOCATED IN COOK COUNTY, ILLINOIS. NOTHING IN THIS PARAGRAPH SHALL AFFECT OR 
IMPAIR LENDER'S RIGHT TO SERVE LEGAL PROCESS IN ANY MANNER PERMITTED BY LAW 
OR LENDER'S RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWERS OR 
THEIR PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION.

     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 invalid under such law, such 
provision shall be ineffective to the extent of such prohibition or provision 
invalidity, without invalidating the remainder of or the remaining such 
provisions of this Note.

for that certain Promissory Note dated as of May 9, 1997 in the original 
principal amount of $3,000,000.00 made by Borrower to the order of Lender. 
This Note represents a continuation of obligations evidenced by said note and 
shall not be deemed to be a novation of the indebtedness evidenced thereby 
for a payment of such indebtedness and the making of a new loan by Lender.
