      applicable Prime Rate plus 0.50%.  Interest shall be computed
      and adjusted daily based on the actual number of days elapsed
      in a year of 360 days.  All outstanding unpaid principal and
      accrued interest on the Revolving Loans shall be due and
      payable on the Termination Date for the Revolving Loans.

                  (c)   Each Company may obtain Revolving Loans by
      making a request therefor to the Bank, orally or in writing.
      Such request shall specify a Business Day prior to the
      Termination Date on which such Revolving Loans are to be made
      (the "Borrowing Date"), shall be received by the Bank by 12:00
      Noon (Milwaukee time) three Business Days before the Borrowing
      Date in the case of LIBOR Rate Loans or otherwise by 12:00
      Noon (Milwaukee time) of the Borrowing Date, and shall specify
      the amount of the Revolving Loans requested, whether the
      Revolving Loans are to be LIBOR Rate Loans and, if so, the
      requested Loan Period; provided, however, that within three
      days after any oral request for a Revolving Loan, the Bank
      shall receive from the Company making such request a written
      confirmation in form acceptable to the Bank confirming such
      Company's Revolving Loan request, and the Bank's obligation to
      make further Revolving Loans hereunder to any Company shall be
      suspended until such confirmation has been received by the
      Bank.  In the event of any inconsistency between the
      telephonic notice and the written confirmation thereof, the
      telephonic notice shall control.  The Companies shall be
      obligated, jointly and severally, to repay all Revolving Loans
      notwithstanding the failure of the Bank to receive written
      confirmation, and notwithstanding the fact that the person
      requesting the Revolving Loan was not in fact authorized to do
      so.  No Revolving Loan request shall be modified, altered or
      amended without the prior written consent of the Bank.  Each
      Revolving Loan shall be in the principal amount of the lesser
      of (i) $25,000 or a multiple thereof, (ii) the Maximum
      Available Commitment or (iii) the remaining amount available
      under the applicable Company's Borrowing Sublimit; provided,
      however, that the Companies may not request LIBOR Rate Loans
      in an amount less than $250,000 per request (and additional
      increments of $100,000).  Upon fulfillment of the conditions
      specified in Section 4.2, the Bank shall promptly deposit the
      amount of such Revolving Loan in the general deposit account
      of the Companies maintained at the Bank.

                  (d)   Except for Revolving Loans which are part of
      the Revolving Loan Overadvance, Revolving Loans which are not
      LIBOR Rate Loans may be converted (in increments of $250,000
      (and additional increments of $100,000)) into LIBOR Rate Loans
      by notice from the applicable Company to the Bank meeting the
      requirements of, Section 2.1(c).  At the end of each
      respective Loan Period, LIBOR Rate Loans shall become
      Revolving Loans which are not LIBOR Rate Loans unless and
      until the Company converts such Revolving Loans to LIBOR Rate
      Loans.

                  (f)   On the final day of each fiscal quarter, the
      Company may, upon five Business Days' prior written notice to
      the Bank, permanently reduce the aggregate amount of the
      Revolving Loan Commitment; provided that no such reduction
      shall reduce the aggregate amount of the Revolving Loan
      Commitment to an amount less than the aggregate unpaid
      principal balance of the Master Revolving Credit Note on the
      effective date of such reduction.  Each reduction in the
      Revolving Loan Commitment shall be in a minimum amount of
      $250,000 and in integral multiples of $250,000 above such
      minimum.

      2.2   Overadvance Term Loan.

                  (a)   On the date hereof, the Bank agrees to extend
      to the Companies, jointly and severally, the Overadvance Term
      Loan in an aggregate principal amount of $4,300,000 and such
      Overadvance Term Loan shall be subject to all of the terms and
      conditions set forth in this Agreement.  The Overadvance Term
      Loan made by the Bank to each Company pursuant hereto shall be
      evidenced by the Master Overadvance Term Note.
      Notwithstanding anything contained herein to the contrary, the
      aggregate principal amount of the Overadvance Term Loan
      outstanding to each Company at any time hereunder shall not
      exceed the applicable amount set forth below:

            Company                                   Borrowing Sublimit

            CF                                        $3,300,000
            Ultra                                     $  500,000
            Gilco                                     $  500,000

                  (b)   The Companies shall pay all accrued and unpaid
      interest on the Overadvance Term Loan on the first day of each
      month commencing on the first day of August, 1996, and
      continuing until the Overadvance Term Loan is paid in full.
      Prior to an Event of Default, interest shall accrue on the
      aggregate unpaid principal amount outstanding under the
      Overadvance Term Note at a rate per annum equal to (i) the
      applicable LIBOR Rate or (ii) the applicable Prime Rate plus
      0.375% per annum.  Notwithstanding the foregoing, and so long
      as no Default has occurred and is continuing, the Companies
      may elect to fix the interest rate on all, but not less than
      all, of the outstanding Overadvance Term Loan (provided that
      no such portion of the Loan at the time of such conversion may
      be LIBOR Rate Loans) at the Fixed Term Rate by delivering an
      irrevocable written notice to the Bank at least three Business
      Days prior to the effective date of such election as specified
      therein (the "Fixed Term Rate Borrowing Date"); and,
      thereafter, interest shall accrue on the aggregate unpaid
      principal amount of the Overadvance Term Loan at a rate per
      annum equal to the Fixed Term Rate.  Interest shall be
      computed and adjusted daily based on the actual number of days
      elapsed in a year of 360 days.  The Companies shall pay
      principal outstanding under such Overadvance Term Note in
      thirty-five (35) equal monthly installments of $59,722.22 each
      payable commencing on the first day of July, 1996 and on the
      first day of each month thereafter, and a final payment of the
      balance of all unpaid principal and accrued interest on the
      Termination Date for such Overadvance Term Loan.  Amounts paid
      or prepaid on the Overadvance Term Loan may not be reborrowed.

                  (c)   So long as no Default has occurred and is
      continuing and provided that the Companies have not elected to
      convert the Overadvance Term Loan to the Fixed Term Rate
      pursuant to Section 2.2(b), the portion of the Overadvance
      Term Loan which is not a LIBOR Rate Loan may be converted into
      a LIBOR Rate Loan of at least $250,000 (and additional
      increments of $100,000) by written notice from the requesting
      Company to the Bank and received by Bank by 12:00 p.m.
      (Milwaukee time) three Business Days before the requested
      borrowing date (such date which shall be prior to the
      Termination Date for the Overadvance Term Loan); such notice
      which shall specify the amount of the Overadvance Term Loan to
      be converted and the requested Loan Period.  No Overadvance
      Term Loan conversion request shall be modified, altered or
      amended without the prior written consent of the Bank.  At the
      end of each respective Loan Period, each LIBOR Rate Loan shall
      become an Overadvance Term Loan which is not a LIBOR Rate Loan
      unless and until a Company converts such Overadvance Term Loan
      to a LIBOR Rate Loan.

            2.3   LIBOR Rate Restrictions.

                  (a)   The Companies may request LIBOR Rate Loans only
      so long as the outstanding LIBOR Rate Loans bear no more than
      ten different LIBOR Rates.  The Bank may require any LIBOR
      Rate Loans to be repaid prior to the applicable Termination
      Date for Revolving Loans and may refuse to make LIBOR Rate
      Loans in the event the Bank determines that (i) maintenance of
      the LIBOR Rate Loans would violate any applicable Requirements
      of Law, (ii) the interest rates on LIBOR Rate Loans do not
      accurately reflect the cost of making such Revolving Loans, or
      (iii) deposits in the amount of any LIBOR Rate Loan are not
      available to the Bank in the London interbank market.

                  (b)   In the event the Bank shall incur any loss,
      cost, expense or premium (including, without limitation, any
      loss of profit or loss, cost, expense or premium incurred by
      reason of the liquidation or reemployment of deposits or other
      funds acquired or contracted to be acquired by the Bank to
      fund or maintain LIBOR Rate Loans or the relending or
      reinvesting of such deposits or other funds or amounts paid or
      prepaid to the Bank), as a result of:

                        (i)   any payment of any LIBOR Rate Loans on a
            date other than the last day of the then applicable Loan
            Period for any reason, whether before or after Default,
            and whether or not such payment is required by any
            provisions of this Agreement; or

                        (ii)  any failure by any Company to create,
            borrow, continue or effect by conversion any LIBOR Rate
            Loans on the date specified in a notice given pursuant to
            this Agreement;

      then upon the demand of the Bank, the Companies shall pay to
      the Bank such amount as will reimburse the Bank for such loss,
      cost, expense or premium.  If the Bank requests such a
      reimbursement it shall provide the applicable Company with a
      certificate setting forth the computation of the loss, cost,
      expense or premium giving rise to the request for
      reimbursement in reasonable detail and such certificate shall
      be deemed prima facie correct.

            2.4   Joint and Several Obligations, Etc.

                  (a)   The Obligations shall be joint and several;
      provided, however, that notwithstanding any other provisions
      hereof to the contrary, the maximum liability of each Company
      hereunder and under the Notes shall be limited to the greater
      of (i) the proceeds of loans made by the Bank hereunder to the
      extent such proceeds are advanced, transferred or applied to
      or for the benefit of such Company, and (ii) ninety-five
      percent (95%) of the difference between (A) the present fair
      saleable value of the Company's assets as of the date of this
      Agreement or any subsequent date (if greater, and to the
      extent permitted by law) and (B) the amount of all liabilities
      of the Company, including liabilities under this Agreement and
      the Notes and probable exposure under contingent liabilities,
      as of such date.

                  (b)   The Obligations shall be absolute and
      unconditional unto each Company; each Company unconditionally
      and irrevocably waives each and every defense which, under
      principles of guarantee or suretyship law or otherwise, would
      operate to impair or diminish such liability; and nothing
      whatsoever except actual full payment and performance to the
      Bank of such Obligations shall operate to discharge the
      liability of the Companies hereunder.  Without limitation of
      the foregoing, the Obligations shall not be affected by the
      invalidity or unenforceability of all or part of the
      Obligations with respect to any Company.

                  (c)   The Bank shall not be obligated to:  (a) take
      any steps whatsoever to collect from, or to file any claim of
      any kind against, any Company or any other person or entity
      liable for payment or performance of any of the Obligations;
      or (b) take any steps whatsoever to protect, accept, obtain,
      enforce, take possession of, perfect its interest in,
      foreclose or realize on collateral or security, if any, for
      the payment or performance of any of the Obligations; or (c)
      in any other respect exercise any diligence whatsoever in
      collecting or attempting to collect any of the Obligations by
      any means.

                  (d)   Without limiting the generality of the
      foregoing, there shall be no diminution or impairment of the
      liability of any Company in any respect, if the Bank exercises
      any of the following rights without notice of any kind to the
      Companies:  (a) extends any additional credit to any Company;
      (b) accepts any Collateral, security or guarantee for any
      obligations or any other credit; (c) determines how, when and
      what application of payments, credits and collections, if any,
      shall be made on the Obligations and any other credit and
      accepts partial payments; (d) determines what, if anything,
      shall at any time be done with respect to any collateral or
      security; subordinates, sells, transfers, surrenders, releases
      or otherwise disposes of all or any of such collateral or
      security; and purchases or otherwise acquires any such
      collateral or security at foreclosure or otherwise; and (e)
      with or without consideration grants, permits or enters into
      any waiver, amendment, extension, modification, refinancing,
      indulgence, compromise,settlement, subordination, discharge or
      release of (i) any of the Obligations, (ii) any obligations of
      any other Person liable for payment or performance of any of
      the Obligations, and any agreement relating to such
      obligations and (iii) any collateral or security or agreement
      relating to collateral or security for any of the foregoing.

                  (e)   Each Company hereby unconditionally waives (i)
      presentment, notice of dishonor, protest, demand for payment
      and all notices of any kind, including, without limitation:
      notice of acceptance hereof; notice of the creation of any of
      the Obligations; notice of nonpayment, nonperformance or other
      default on any of the Obligations; and notice of any action
      taken to collect upon or enforce any of the Obligations; (ii)
      any subrogation to the rights of the Bank against any other
      Company, any other claim against any other Company which
      arises as a result of payments made by a Company pursuant to
      this Agreement, and any claim for contribution against any
      other Company whether or not the Obligations have been paid or
      performed in full; and (iii) any setoffs or counterclaims
      against the Bank which would otherwise impair the Bank's
      rights against any Company hereunder.

            2.5   Interest After Default.  After an Event of Default,
each of the Obligations shall bear interest at the rate of 3% per
annum in excess of the applicable rates set forth herein; provided,
that in the case of a LIBOR Rate Loan the maturity of which is
accelerated, such LIBOR Rate Loan shall bear interest for the
remainder of the applicable Loan Period at a rate equal to 3% plus
the higher of the rate on the LIBOR Rate Loan or the rate on
Revolving Loans or the portion of the Term Loan, as the case may
be, which are not LIBOR Rate Loans.  In no event shall the interest
rates under the Notes exceed the highest rate permitted by law.


            2.6   Loan Account.  The Bank will enter as a debit to the
Loan Account the aggregate principal amount of each Obligation as
disbursed or issued from time to time by the Bank.  The Bank shall
also record in the Loan Account, in accordance with the Bank's
customary accounting practices: accrued interest and all other
charges, expenses and other items properly chargeable to any
Company hereunder or under the Related Documents; all payments made
by any Company with respect to the Obligations, if any; and all
other appropriate debits and credits.  The debit balance of the
Loan Account shall reflect the amount of the Obligations and other
appropriate charges hereunder.  Not more frequently than once each
month, the Bank shall render a statement of account of the Loan
Account including, with respect to Revolving Loans and the
Overadvance Term Loan, a statement of the outstanding principal
balance, Loan Period and applicable LIBOR Rate for each LIBOR Rate
Loan, which statement shall be considered correct and accepted by
the Companies and conclusively binding upon the Companies unless
any Company notifies the Bank to the contrary within 30 days of the
mailing of such statement by the Bank to the Companies; provided,
however, that the failure of the Bank to record any of the
foregoing items in the Loan Account shall not limit or otherwise
affect the Companies' joint and several obligation to repay the
Obligations.

            2.7   Lockbox.

                  (a)   The Companies agree that following a Default,
      and upon the request of the Bank, they shall immediately
      direct each of their respective account debtors and other
      obligors to make payments due under their accounts,
      instruments and/or chattel paper directly to a special lockbox
      to be under the exclusive control of the Bank.

                  (b)   Upon the establishment of the special lockbox
      referred to in Section 2.7(a), the Companies authorize and
      direct the Bank to deposit into a special collateral account
      to be established and maintained by the Bank all drafts,
      checks and cash payments received in said lockbox or otherwise
      received by the Bank.  All deposits in said collateral account
      shall constitute proceeds of Collateral.  The Bank shall apply
      finally collected funds on deposit in said collateral account
      immediately to the Loan Account as payment of the Obligations,
      in such order of application as the Bank may determine;
      provided, however, that the Bank shall not apply such
      collected funds to prepay the Overadvance Term Loan except
      upon any Company's request or unless an Event of Default has
      occurred.  The Companies agree that they shall promptly
      deliver to the Bank for deposit in said collateral account all
      payments received by them, including, without limitation, all
      payments on accounts, instruments and chattel paper, all cash
      received by each Company and all other proceeds of Collateral.
      All payments shall immediately be delivered to the Bank in the
      form received (except for the applicable Company's endorsement
      where necessary) and, until so deposited, shall be held in
      trust by such Company for and as the exclusive property of the
      Bank and shall not be commingled with any funds or property of
      such Company.

            2.8   Payments.  Whenever any payment to be made hereunder
shall be stated to be due on a day which is not a Business Day,
such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the
computation of payment of interest on the Notes.  The Bank may
debit to the depository accounts maintained by the Companies with
the Bank all payments on the Obligations when due without prior
notice to or consent of any Company.

            2.9   Prepayments.

                  (a)   Optional Prepayments.  The Companies may at
      their option, at any time upon three (3) days' prior written
      notice to the Bank, prepay the Obligations, in whole or in
      part.  Partial prepayments shall be in the principal amount of
      $100,000 or a multiple thereof, together with accrued interest
      to the date of prepayment on the amount prepaid.  There shall
      be no prepayment premium or penalty except: (i) as provided in
      Section 2.3(a); and (ii) that, if the Companies have converted
      the Overadvance Term Loan to the Fixed Term Rate, the Company
      shall upon prepayment or partial prepayment of such
      Overadvance Term Loan (whether upon mandatory or optional
      redemption, acceleration or maturity) pay the Bank the Make
      Whole Payment on the date of prepayment.  The Companies agree
      that the Make Whole Payment constitutes a reasonable method of
      measuring the Bank's estimated loss in the event of a
      prepayment, that it is not a penalty, and that the Bank's
      determination of the Make Whole Payment, in the absence of
      manifest error, shall be conclusive, final, and binding on the
      Companies.

                  (b)   Mandatory Prepayment.  

                        (i)   At any time that the aggregate principal
      amount of Revolving Loans outstanding exceeds the lesser of
      the Revolving Loan Commitment or the Borrowing Base, the
      Companies shall immediately pay the amount of such excess in
      immediately available funds, together with interest accrued on
      the amount of the payment.

                        (ii)  So long as any amounts remain outstanding
      under the Overadvance Term Loan, the Companies jointly and
      severally agree to make an Excess Cash Flow Payment on April
      30 of each year, commencing on April 30, 1997 through and
      including April 30, 1999, based on year-end audited financial
      statements.  All Excess Cash Flow Payments shall be applied to
      reduce the regularly scheduled principal installments on the
      Overadvance Term Loan in the inverse order of their maturity.

            2.10  Effect of Regulatory Change.  In the event of a
Regulatory Change deemed by the Bank in good faith to be material,
the Companies shall pay to the Bank (within ten days after notice
by the Bank to the Companies of such Regulatory Change) such
amounts as the Bank deems reasonably necessary to compensate the
Bank for the increase in the cost of making or maintaining the
Obligations or the reduction in the rate of return to the Bank on
the Obligations resulting from the Regulatory Change.

            2.11  Security.  Payment of all Obligations shall be
secured, subject only to Permitted Liens, by a first lien on all of
the Property in accordance with this Agreement and the Related
Documents.

            2.12  No Obligation to Extend or Forbear.  The Companies
acknowledge and agree that the Bank (a) upon execution hereof, has
no duty or obligation of any kind to, and has made no
representations of any kind or nature that the Bank will, extend
credit or any other kind of financial accommodations to any Company
after the Termination Date, or forbear at any time from the
exercise of any of its rights or remedies under this Agreement, the
Related Documents and applicable law, and (b) may at any time, in
its sole and absolute discretion, exercise whatever rights and
remedies the Bank may have under this Agreement, the Related
Documents and applicable law.  All Obligations shall be due in full
on the Termination Date without further demand.


            SECTION 3   REPRESENTATIONS AND WARRANTIES

            In order to induce the Bank to enter into this Agreement
and make and incur the Obligations as herein provided, each Company

      applicable periods, and present fairly the financial condition
      of the Company as of such dates and the results of its
      operations and cash flows for the periods then ended.  The
      balance sheets and footnotes thereto show all known

                  (b)   The financial forecasts dated March 11, 1996
      and furnished to the Bank by the Company are based on

which the Company is a party or by which it is bound.

            3.5   Taxes.  The Company has filed all federal, state,

set forth in this Agreement, the Related Documents or other

            3.19  Solvency.  Each Company is not "insolvent," nor will
each Company's incurrence of loans, direct or contingent, to repay
the Obligations render any Company "insolvent."  For purposes of
this subsection 3.19, a corporation is "insolvent" if (i) the
"present fair salable value" (as defined below) of its assets is
less than the amount that will be required to pay its probable
liability on its existing debts and other liabilities (including
contingent liabilities) as they become absolute and matured; (ii)
its property constitutes unreasonably small capital for it to carry
out its business as now conducted and as proposed to be conducted
including its capital needs; (iii) it intends to, or believes that
it will, incur debts beyond its ability to pay such debts as they
mature (taking into account the timing and amounts of cash to be
received by it and amounts to be payable on or in respect of debt
of it), or the cash available to it after taking into account all
of its other anticipated uses of the cash is anticipated to be
insufficient to pay all such amounts on or in respect of its debt
when such amounts are required to be paid; or (iv) it believes that
final judgments against it in actions for money damages will be
rendered at a time when, or in an amount such that, it will be
unable to satisfy any such judgments promptly in accordance with
their terms (taking into account the maximum reasonable amount of
such judgments in any such actions and the earliest reasonable time
at which such judgments might be rendered), or the cash available
to it after taking into account all other anticipated uses of its
cash, is anticipated to be insufficient to pay all such judgments
promptly in accordance with their terms.  For purposes of this
subsection 3.19, the following terms have the following meanings:
(x) the term "debts" includes any legal liability, whether matured
or unmatured, liquidated, absolute, fixed or contingent, (y) the
term "present fair salable value" of assets means the amount which
may be realized, within a reasonable time, either through
collection or sale of such assets at their regular market value and
(z) the term "regular market value" means the amount which a
capable and diligent businessman could obtain for the property in
question within a reasonable time from an interested buyer who is
willing to purchase under ordinary conditions.

                  (b)   specified in clauses (a), (b), (c), (d), (e),
      (f), (i), (j), (k) or (l) of Section 7.1, the Bank may,
      without presentment, notice, demand or action of any kind, all
      of which are hereby waived:  (i) immediately terminate the
      Bank's obligation to make or incur any Obligations, and the
      same shall immediately terminate; and (ii) declare the entire
      amount of the Obligations immediately accelerated, due and
      payable.

                  (c)   the Bank may at any time without prior notice
      or demand set off against any credit balance or other money
      now or hereafter owed it by the Bank all or any part of the
      Obligations.  Each Company hereby grants to the Bank a
      security interest in and lien on any such credit balance or
      other money.

                  (d)   the Bank shall have all of the rights and
      remedies provided to the Bank by the Related Documents, at law
      and in equity, by statute or otherwise, and no remedy herein
      conferred upon the Bank is intended to be exclusive of any
      other remedy and each remedy shall be cumulative and shall be
      in addition to every other remedy given hereunder or now or
      hereafter existing at law, in equity, by statute or otherwise.
      In addition to and not in lieu of any other right or remedy
      the Bank might have, the Bank at any time and from time to
      time at its election may (but shall not be required to) do or
      perform or comply with or cause to be done or performed or
      complied with anything which any Company may be required to
      do, perform or comply with and the Companies shall reimburse
      the Bank upon demand for any cost or expense which the Bank
      may incur in such respect, together with interest thereon at
      the rate equal to the rate payable under the Master
      Overadvance Term Note following an Event of Default from the
      date of such demand until paid.  No failure or delay on the
      part of the Bank in exercising any right or remedy hereunder
      shall operate as a waiver thereof nor shall any single or
      partial exercise of any right hereunder preclude any further
      exercise thereof or the exercise of any other right or remedy.


            SECTION 8   MISCELLANEOUS

            8.1   Assignability; Successors.  The provisions of this
Agreement shall inure to the benefit of and be binding upon the
permitted successors and assigns of the parties hereto.  Each of
the Companies' rights and liabilities under this Agreement and the
Related Documents are not assignable in whole or in part without

sell, assign or transfer to one or more banks or other entities
other than any competitor of the Companies ("Participants")
interests in any Note held by the Bank or any other interest of the
Bank in the Obligations.  Each Company authorizes the Bank to
disclose to any Participant or prospective Participant any and all
financial information in the Bank's possession concerning each such
Company and its Affiliates which has been delivered to the Bank by
or on behalf of such Company.  Each Company agrees that upon the
occurrence of any Event of Default each Participant shall be deemed
to have the right of setoff in respect of its participating
interest in the Obligations to the same extent as if the amount of
its participating interest were owing directly to it as a Bank
under this Agreement.

            8.2   Survival.  All agreements, covenants,
representations and warranties made herein and in the Related
Documents shall survive the execution and delivery of this
Agreement and the Related Documents, the making of the Obligations
and the termination of this Agreement.

Documents shall be governed by the internal laws of the State of
Wisconsin.

            8.4   Counterparts; Headings.  This Agreement may be
executed in several counterparts, each of which shall be deemed an
original, but such counterparts shall together constitute but one
and the same agreement.  The descriptive headings in this Agreement
are inserted for convenience of reference only and shall not affect
the construction of this Agreement.

            8.5   Entire Agreement; Amendments.  This Agreement, the
Exhibits and Schedules attached hereto, and the Related Documents
contain the entire understanding of the parties with respect to the
subject matter hereof, and supersede all other understandings, oral
or written, with respect to the subject matter hereof.  No
amendment, modification, alteration, or waiver of the terms of this
Agreement or consent required under the terms of this Agreement
shall be effective unless made in a writing, which makes specific
reference to this Agreement and which has been signed by the party
against which enforcement thereof is sought.  Any such amendment,
modification, alteration, waiver or consent shall be effective only
in the specific instance and for the specific purpose for which
given.

            8.6   Notices.  All communications or notices required or
permitted by this Agreement shall be in writing and shall be deemed
to have been given or made when delivered in hand, deposited in the

such provision or the remaining provisions of this Agreement.

            8.8   Further Assurances.  Each Company severally agrees
to do such further acts and things, and to execute and deliver such
additional conveyances, assignments, agreements and instruments, as
the Bank may at any time request in connection with the
administration or enforcement of this Agreement or the Related
Documents or in order better to assure and confirm unto the Bank
its rights, powers and remedies hereunder.

            8.9   Conflicts and Ambiguities.  In the event of any

law (a) shall be deemed in every respect effective service of
process upon it in any such suit, action or proceeding, and (b)
shall be taken and held to be valid personal service upon personal

preclude the Bank from bringing an action or proceeding in respect
hereof in any other country, state or place having jurisdiction
over such action.  Each Company hereby irrevocably waives, to the
fullest extent permitted by law, any objection which it may now or
hereafter have to the laying of the venue of any such suit, action
