                                    RECITALS

                  WHEREAS, the Borrower, the Agent and the Lenders are parties

                  WHEREAS, the Borrower wishes, and the Agent and the Lenders
are willing, to amend certain provisions of the Secured Credit Agreement and to

                  WHEREAS, First Source Financial LLP and LaSalle Business

Agreement as of the date hereof; and

                  NOW, THEREFORE, in consideration of the mutual agreements

                                    AGREEMENT

         1. Definitions. Capitalized terms used but not otherwise defined herein
shall have the meanings as set forth in the Secured Credit Agreement.

         2. Waiver. The Lenders hereby waive any Unmatured Event of Default or
Event of Default caused by the Borrower's failure to comply with the Net Worth,
Debt to EBITDA Ratio, Interest Coverage Ratio and Fixed Charge Coverage Ratio
covenants set forth in Sections 11.32(a), (b), (c) and (d) of the Secured Credit

the Borrower may not incur or continue any LIBOR Rate Loans (or convert any
Prime Rate Loans into LIBOR Rate Loans) from the date hereof until the date on
which the Borrower demonstrates to the Agent and the Lenders, by the delivery of
a Compliance Certificate and the financial statements required under Section
11.1(b), its compliance with the financial covenant set forth in Sections
11.32(d).

         3.       Amendments to Secured Credit Agreement.

         (a) Section 2.12.10 of the Secured Credit Agreement is hereby amended
by deleting it in its entirety and replacing it with the following:

                           SECTION 2.12.10 CASH COLLATERAL.

                           (a) DEPOSIT OF CASH COLLATERAL UPON AN EVENT OF
         DEFAULT. Upon demand by Agent or the Required Lenders after the
         occurrence of any Event of Default, Borrower shall deposit in an
         account (the "LETTER OF CREDIT CASH COLLATERAL ACCOUNT") maintained
         with FSFP in the name of Agent, for the ratable benefit of Agent and
         the Lenders, with respect to each Letter of Credit then outstanding
         (other than the RIC Letter of Credit, which does not constitute a
         Letter of Credit hereunder), promptly upon such demand, cash or Cash
         Equivalents in an amount equal to 110% of the greatest amount for which
         such Letter of Credit may be drawn.

                           (b) TERMS OF LETTER OF CREDIT CASH COLLATERAL
         ACCOUNT. Any funds held in the Letter of Credit Cash Collateral Account
         shall be promptly applied by Agent to reimburse the Issuing Bank for
         drafts drawn from time to time under the Letters of Credit. Such funds,
         if any, remaining in the Letter of Credit Cash Collateral Account
         following the termination of all Letters of Credit and the payment of
         all Reimbursement Obligations in full shall, unless Agent is otherwise
         directed by a court of competent jurisdiction, be promptly paid over to
         Borrower. Upon the deposit of any amounts in the Letter of Credit Cash
         Collateral Account and, in any event, on or before the Revolving Loan
         Termination Date, Borrower shall enter into a security agreement in
         form and substance satisfactory to Agent, pledging to Agent, for the
         benefit of Agent and the Lenders, a security interest in all Cash
         Equivalents delivered to Agent pursuant to the terms hereof. If no
         Unmatured Event of Default or Event of Default has occurred and is
         continuing, the Borrower may direct the investment of funds maintained
         in the Letter of Credit Cash Collateral Account in Cash Equivalents.
         Upon the occurrence and during the continuance of an Unmatured Event of
         Default or Event of Default, Borrower shall have no control over funds
         deposited in the Letter of Credit Cash Collateral Account, which funds
         shall be invested by Agent from time to time in its discretion in Cash
         Equivalents.

         (b) Section 2 of the Secured Credit Agreement is hereby amended by
adding the following new Section 2.15 immediately following Section 2.14:



                                       2
<PAGE>




         SECTION 2.15 LASALLE LETTER OF CREDIT. Notwithstanding anything to the
contrary contained in this Agreement, Borrower may (a) cause LaSalle National
Bank (the "RIC ISSUING BANK") to issue a letter of credit (the "RIC LETTER OF
CREDIT") for the account of Borrower in the face amount not to exceed $150,000,
to support the obligations of Borrower to Royal Indemnity Company, and (b)
pledge to the RIC Issuing Bank as security for its reimbursement obligations to
the RIC Issuing Bank in respect of the RIC Letter of Credit, cash or Cash
Equivalents (the "RIC CASH COLLATERAL") in an amount not to exceed 100% of the
aggregate undrawn face amount of the outstanding RIC Letter of Credit and all
fees and other amounts due or which may become due with respect thereto. The RIC
Letter of Credit shall not be a Letter of Credit under this Agreement and,
therefore, no LC Guaranty shall be issued in respect thereof. Notwithstanding
anything to the contrary contained in Section 6.2 hereof, Borrower may maintain
a depositary account (the "RIC CASH COLLATERAL ACCOUNT") with the RIC Issuing
Bank; provided, that no funds other than RIC Cash Collateral shall be maintained
in such RIC Cash Collateral Account; provided, further, that (i) Borrower shall
have irrevocably instructed the RIC Issuing Bank, at the request of Agent, to
provide Agent with information concerning the RIC Cash Collateral Account, (ii)
the RIC Issuing Bank shall have acknowledged such instructions in writing for
the benefit of Agent, and (iii) at any time when an Event of Default or
unmatured Event of Default has occurred and is continuing Borrower shall, at
Agent's request, promptly cause the RIC Issuing Bank to provide Agent with daily
reports of the balance in the RIC Cash Collateral Account. Upon the
establishment of the RIC Cash Collateral Account, Borrower shall enter into a
security agreement in form and substance satisfactory to Agent, pledging to
Agent, for the benefit of Agent and the Lenders, a second priority security
interest (subject only to the security interest of the RIC Issuing Bank in the
RIC Cash Collateral) in the RIC Cash Collateral Account and all cash and Cash
Equivalents held therein.

         (c) Section 4.1 of the Secured Credit Agreement is hereby amended by
deleting it in its entirety and replacing it with the following:

                  SECTION 4.1 INTEREST RATES. Subject to Section 4.3, Borrower
hereby promises to pay interest on the outstanding principal amount of each Loan
for the period commencing on the date thereof until such Loan is paid in full,
at a rate per annum determined by reference to the Prime Rate or the LIBOR Rate,
respectively. The applicable basis for determining the rate of interest shall be
selected by Borrower at the time a borrowing is requested pursuant to Section
2.3 or at the time a Notice of LIBOR Activity is given pursuant to Section 4.4,
as the case may be. If on any day any portion of any Loan is outstanding with
respect to which notice has not been given to Agent in accordance with the terms
of this Agreement specifying the basis for determining the rate of interest
thereon, then for that day, such portion of such Loan shall be a Prime Rate Loan
and shall bear interest at a rate determined by reference to the Prime Rate.
Subject to Section 4.3, (i) each Prime

                                       3
<PAGE>

Rate Revolving Loan and LIBOR Rate Revolving Loan shall bear interest at a rate
per annum determined as follows: (a) if it is a Prime Rate Revolving Loan, then
at the sum of the Prime Rate in effect from time to time plus one and
one-quarter of one percent (1.25%); or (b) if it is a LIBOR Rate Revolving Loan,
then at the sum of the LIBOR Rate for the applicable Interest Period plus three
and one-quarter of one percent (3.25%) (the "LIBOR REVOLVING MARGIN"); and (ii)
each Prime Rate Term Loan and LIBOR Rate Term Loan shall bear interest at a rate
per annum determined as follows: (a) if it is a Prime Rate Term Loan, then at
the sum of the Prime Rate in effect from time to time plus one and
three-quarters of one percent (1.75%); or (b) if it is a LIBOR Rate Term Loan,
then at the sum of the LIBOR Rate for the applicable Interest Period plus three
and three-quarters of one percent (3.75%).

         (d) Section 10.27 of the Secured Credit Agreement is hereby amended by
deleting it in its entirety and replacing it with the following:

                  SECTION 10.27 SOLVENCY. Borrower and its Subsidiaries are
Solvent, as determined on a consolidated basis, both before and after giving to
the execution and delivery of this Agreement and any of the other Related
Documents to which Borrower or any Subsidiary is a party and consummation of the
transactions contemplated hereunder or thereunder, including, without
limitation, the Related Transactions.

         (e) Section 11 of the Secured Credit Agreement is hereby amended by

                  SECTION 11.34 KEY MAN INSURANCE POLICY. On or before July 15,
1999, the Borrower shall deliver to the Agent a duly executed assignment of a
$5,000,000 life insurance policy on Richard Hinrichs in form and substance
satisfactory to the Agent.

         4. Representations and Warranties. To induce the Agent and the Lenders

Contractual Obligation binding upon such entity. This Agreement is the legal,
valid, and binding obligation of the Borrower enforceable against the Borrower
in accordance with its respective terms.

         (b) Certain Agreements. To the best of the Borrower's knowledge, on the
date hereof all warranties of the Borrower thereto set forth in the Secured

         (b) Governing Law. This Agreement shall be a contract made under and
governed by the laws of the State of Illinois, without regard to conflict of
laws principles. Wherever possible each provision of this Agreement shall be
interpreted in such manner to be effective and valid under applicable law, but
if any provision of this Agreement shall be prohibited by or invalid under such
law, such provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provisions or the
remaining provision of this Agreement.

         (c) Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties on separate counterparts, and each
such counterpart shall be deemed to be an original, but all such counterparts

         (f) Continued Effectiveness. Notwithstanding anything contained herein,
the terms of this Agreement are not intended to and do not serve to effect a
novation as to the Secured Credit Agreement, any Note or any of the Collateral
Documents provided to furnish security therefor. The parties hereto expressly do
not intend to extinguish the Secured Credit Agreement, any Note or the
Collateral Documents. Instead, it is the express intention of the parties hereto
to reaffirm the existence of the indebtedness created under the Secured Credit
Agreement which is evidenced by Notes and secured by the various Collateral
Documents. The Secured Credit Agreement and each of the Related Documents as
amended hereby remain in full force and effect. The execution, delivery and
effectiveness of this Agreement shall not operate as a waiver of any right,
power or remedy of the Lenders or the Agent under the Secured Credit Agreement
or any Related Document to which the Lenders and the Agent are a party nor,
except as set forth in Section 2 hereof, constitute a waiver of any provision in
or Event of Default or Unmatured Event of Default (now or hereafter existing)
under the terms of the Secured Credit Agreement or any Related Document.
