LOAN PARTICIPATION CERTIFICATE AND AGREEMENT


        THIS PARTICIPATION AGREEMENT is entered into as of this 1st day of
   May, 1997 (the "Agreement") by and between BANDO McGLOCKLIN SMALL BUSINESS
   LENDING CORPORATION (the "Company") and SECURITY BANK, SSB (the "Bank").

                                R E C I T A L S:

        WHEREAS, the Company has entered into Commitment and Loan Agreements
   (each a "Loan Agreement" and collectively the "Loan Agreements") with
   those persons listed on Exhibit A (each a "Borrower" and collectively the
   "Borrowers"), pursuant to which, among other things, the Company made
   loans to Borrowers evidenced by each Borrower's Note in the principal
   amount, at the interest rate, dated and maturing on the date all as listed
   on Exhibit A (each a "Note" and collectively the "Notes"); and

        WHEREAS, the Bank desires to purchase from the Company, and the
   Company desires to sell, a participation in the Loan Agreements, the Notes
   and all other legal documents and instruments creating or evidencing the
   Company's loan (each a "Loan" and collectively the "Loans") to the
   Borrower and all other legal documents and instruments securing or
   guarantying the same (collectively, the "Loan Documents"), subject to the
   terms and conditions set forth herein.

        NOW, THEREFORE, in consideration of the above premises and for other
   good and valuable consideration, the receipt and sufficiency of which are
   hereby acknowledged, the parties hereto agree as follows:

        1.  Definitions.  As used in this Agreement, the following
   capitalized terms shall have the following meanings:

             (a)  "Participant" means the Company and the Bank.

             (b)  "Participation" of a Participant means the undivided
        interest of such Participant in the Note and Loan.

        2.  Sale, etc.  The Company hereby sells, transfers and assigns and
   the Bank hereby agrees to purchase from the Company, an undivided
   Participation in the Notes and Loan Documents (in the amounts which are
   listed on Exhibit A) for the aggregate amount of $21,811,236.88, the
   receipt of which is hereby acknowledged by the Company.  The Company
   retains a Participation in the Note and Loan, which is and shall remain
   subordinate to the Bank's rights and interest in the Loan and Loan
   Documents and to Bank's full recovery of its participation, including any
   interest or other amounts due in connection therewith.  The Company will
   deliver to Firstar Trust company, Milwaukee, Wisconsin ("Document
   Custodian") the original Loan Documents, as agent for the Participants,
   subject to the rights and duties herein described retained by the Company.

        The Bank shall be entitled to interest on the aggregate amount of its
   Participation at the rate of 7.90% per annum, payable in arrears on the
   10th day of each calendar month commencing on the 10th day of the first
   calendar month following the date hereof and continuing on the 10th day of
   each calendar month until June 30, 1997.  Subsequent to an event of
   default in the payment of any funds due on any Note, the Bank shall be
   entitled to interest on the aggregate amount of its Participation at the
   rate of 2.0% above the rate otherwise in effect for the period that the
   default is left uncured. Interest shall be determined on a daily basis
   using the exact amount invested or remaining invested in the
   Participation, including amounts due to be paid the Bank under Section 3
   hereof, but not yet received by the Bank.  All computation of interest
   shall be made on the basis of a year of 360 days, composed of 12 months of
   30 days in each month, using the actual number of days occurring for any
   partial month for which such interest is payable.  For the month beginning
   July 1, 1997 and for each successive month thereafter, the interest rate
   shall be equal to the one month London Interbank Offered Rate plus 1.5%.
   The one month London Interbank Offered Rate means the rate published in
   The Wall Street Journal on the first business day of each month.  

        The Company shall furnish the Bank a written computation of interest
   with each payment of interest, provided, however, that the Bank shall make
   the final determination of interest, which determination shall be
   conclusive and binding, absent manifest error.

        The Company shall pay a late payment fee equal to 5% of the amount of
   any payment of interest, principal or other amounts due the Bank that is
   not paid when due on any such late payments accepted by the Bank.

        In the event that (i) the Company offers to repurchase, and the Bank
   agrees to resell, any Note or Notes to the Company for the full amount of
   the Bank's Participation, (ii) there is a payment in full prior to
   maturity of any Note, or (iii) there is a payment in full of any Note upon
   its stated maturity which occurs on or before July 1, 2000, then the Bank
   agrees that, subject to the Bank's approval of the Loan, it will purchase
   and the Company agrees that it will sell, an additional Note or Notes for
   an amount not to exceed in the aggregate the amount of the Bank's
   Participation that is repurchased by the Company or that has been repaid
   by the Borrower to the Company.

        In the event that there is a payment in full of any Note at or prior
   to its stated maturity as provided in the preceding paragraph, the Bank
   agrees that, subject to the Bank's approval of the Loan, it will purchase
   and the Company agrees that it will sell an eightyfive percent (85%)
   undivided Participation in an additional Note or Notes for an amount not
   to exceed in the aggregate the amount of the Bank's Participation that is
   paid at maturity within five (5) years from the date hereof or is prepaid
   by the Borrower to the Company, provided that:

             The Company shall provide to the Bank not less than five (5)
        Business Days prior to the Company's receipt of the prepayment from
        the Borrower:

                  a) an Officer's Certificate setting forth the original
             principal amount of the Note being paid or prepaid, the stated
             maturity of the Note being prepaid, the amount being paid, and
             the interest rate for said Note as of the date of payment; and

                  b) an Officer's Certificate setting forth the original
             principal balance of the Note (or Notes) to be purchased by the
             Bank, the stated maturity of the Note (or Notes) to be purchased
             by the Bank, the then-current principal balance of the Note (or
             Notes) to be purchased by the Bank, and the then-current
             interest rate for said Note (or Notes).

        The Company may, at any time, repurchase any Note or Notes for the
   full amount of the Bank's Participation in such Note or Notes, together
   with any interest accrued thereon pursuant to Section 2 hereof. In the
   event that the Company exercises its option to repurchase any Note or
   Notes pursuant to this agreement, then: a) the Company shall pay to the
   Bank on the date of the repurchase, a repurchase premium equal to 1.5% of
   the Bank's Participation in such Note or Notes; and (ii) the Bank shall be
   under no obligation to purchase an additional Note or Notes in
   substitution therefor.

        3.  Collection and Allocation of Payments.

             (a) All payments on account of principal, together with any
   release fees, condemnation awards, renewal or extension fees, insurance
   proceeds, payments received from guarantors or sureties, proceeds of
   setoff and all proceeds of collection or from the sale or liquidation of
   collateral for any Note (together, "Collections") and all payments of
   interest received by the Company shall be allocated to, and paid by the
   Company to the Bank as hereinafter set forth.  On the tenth (10th) day of
   each month, the Company agrees to remit to the Bank:

             (i) Interest in the amount determined under Section 2 hereof for
        the preceding month just ended, including interest on any amount of
        interest not paid when due;

             (ii)  Eightyfive percent (85%) of any prepayment penalties or
        fees on the Notes;

             (iii)  Eightyfive percent (85%) of Collections prior to maturity
        of the Notes received during the preceding month just ended; and

             (iv) One hundred percent (100%) of Collections after maturity of
        the Notes (whether by acceleration or otherwise) received during the
        preceding month just ended, up to a maximum of the Bank's
        Participation therein.

   In the event that all payments of principal received by the Company on any
   Note, including all Collections, are not sufficient to repay the balance
   of the Bank's Participation in any such Note, the Company agrees to
   repurchase the unpaid principal balance of the Bank's Participation, plus
   interest and other fees or charges due the Bank thereon, upon demand by
   the Bank.

             (b) All payments of principal and interest due under this
   Agreement shall be made by wire transfer of immediately available funds by
   the Company to the Bank no later than 12 p.m. on the dates when due.  No
   later than the preceding Business Day, the Company shall notify the Bank
   of the anticipated amount or each remittance, together with sufficient
   text to identify the Loan Participation Certificate and Agreement to which
   such remittance relates, and the amount being remitted as interest, fees
   or principal, as the case may be.

        4.  Loan Servicing.  Until such time as the Bank has fully recovered
   the amount invested in this Participation plus interest on the amount of
   this Participation, the Company shall service and manage the Notes and
   Loan Documents in accordance with its usual practices with respect to
   loans of that type and shall exercise the same degree of care and shall
   adhere to the same standards of conduct as would be the case if there were
   no participation in such Loan, without cost or charge to the Bank.  The
   Company shall provide to the Bank a copy of all paid real estate tax bills
   and all certificates of fire and hazard insurance provided by the
   Borrowers to the Company. The Company shall pay all expenses incurred in
   performance by the Company of its servicing obligations hereunder,
   including expenses incurred in administering, collecting, enforcing or
   protecting the Notes and Loan Documents.  The Company shall not be liable
   to the Bank for any action of, or failure to act or mistake on the part of
   any of the Company's agents, officers, employees or attorneys with respect
   to any transaction relating to the Loan, provided the Company has acted in
   good faith and has not been guilty of any willful misconduct.

        5.  Covenants.  Except as provided in Section 9 hereof, neither the
   Company not the Bank shall, without the prior written consent of the other
   Participant:

             (a) Amend the Note or any of the Loan Documents if the effect of
        any such amendment is to extend the term of any Note, change the
        amount, frequency or time for any payment due under the Note or
        change the interest rate or other fees or charges due or payable
        under the Note or any of the Loan Documents;

             (b) Consent to any waiver of default or forbearance in
        connection with any Note or Loan document; and

             (c) Release or waive any security or any claim against the
        Borrower or any guarantor or surety of the Borrower's obligations
        under the Note and the Loan Documents.

        6.  Financial Information.  The Company shall furnish to the Document
   Custodian copies of all annual financial statements of each Borrower.  The
   Company will furnish to the Bank, upon request, copies of interim
   financial statements of any Borrower, appraisals, title reports,
   environmental reports or any other information relating to a Borrower and
   a Borrower's Loan.  The Company shall not be responsible for the accuracy
   of any information given to the Company by the Borrowers.  The Company
   shall promptly notify the Bank of any material inaccuracy or omission in
   information of which the Company has knowledge, provided, however, that
   the Company has no duty to investigate the accuracy of the information.

        7.  Indemnification.  The Company agrees to indemnify and hold the
   Bank harmless from any and all claims, losses, penalties, fines,
   forfeitures, legal fees and related costs, judgments and any other costs
   that the Bank may sustain as a result of the Company's obligations under
   the Note and other Loan Documents, or this Agreement.

        8.  Borrower Default and Remedies.  Upon a default in the payment of
   any funds due on any Note, or in the performance of any term in any of the
   Loan Documents, the Company shall promptly notify the Bank of the default. 
   In the event any default as described above is left uncured for a period
   of ninety (90) days, the Company shall accelerate the maturity of the
   entire indebtedness of such Note and commence foreclosure or other
   appropriate proceedings to collect the Note and to enforce its rights
   against any collateral securing the Note.

        9.  Lender Default and Remedies.  In the event that Company shall
   become the subject of liquidation, reorganization, receivership or similar
   proceedings or a Default occurs, the Bank will have the right to
   administer and service, or to collect and enforce, as the case may be, the
   Note and the Loan Documents in its own name and for its own account and in
   so doing, may, without limitation, notice or consent (notice and consent
   being hereby waived by the Company) (a) amend the Note or any of the Loan
   Documents; (b) change the nature or time of payment of the obligations
   referred to therein; (c) consent to any waiver, modification, forbearance
   or revision of the Note or any of the Loan Documents; and (d) release or
   waive any security or any claim against the Borrower or any guarantor or
   surety of the Borrower's obligations under the Note and the Loan
   Documents.

      10.  General.

             (a)  This Agreement may only be changed, waived, discharged or
        terminated by written agreement signed by the Company and the Bank. 
        The Company may not repurchase the unpaid principal balance of the
        Bank's Participation without the Bank's consent.

             (b)  Neither the execution of this Agreement nor the purchase of
        the Participation by the Bank is intended to be, nor shall it be,
        construed to be, the formation of a partnership or joint venture
        between the Company and the Bank.

             (c)  The delivery of the Note and the Loan Documents to the
        Document Custodian shall constitute a sale and assignment of a
        Participation in the Note and the Loan Documents to the extent of the
        amounts stated herein.  No payment by the Bank to the Company on
        account of any such Participation shall evidence a loan by the Bank
        to the Company.

             (d)  The Agreement embodies the entire agreement and
        understanding between the Company and the Bank and supersedes all
        prior agreements and understandings between the Company and the Bank
        relating to the subject matter thereof.

             (e)  Any provision of this Agreement which is prohibited or
        unenforceable in any jurisdiction shall, as to such jurisdiction, be
        ineffective to the extent of such prohibition or unenforceability
        without invalidating the remaining provisions hereof or affecting the
        validity or enforceability of such provision in any other
        jurisdiction.

             (f)  All of the terms, covenants and conditions herein contained
        inure to the benefit of and are binding upon the Participants, their
        successors and assigns.

             (g)  This Agreement is governed by the laws of the State of
        Wisconsin.

             (h)  The Company acknowledges that it is acting as and will
        fulfill its duties and obligations hereunder as a fiduciary to the
        Bank.

             (i)  None of the terms, covenants, conditions, agreements or
        provisions contained in this Agreement confer any rights upon, or are
        enforceable by the Borrower, or its successors, legal representatives
        or assigns.

   Dated as of the date first above written.
