        (a)  The Borrowers shall have the right at any time and from time to
   time upon two (2) Business Days' prior written notice to the Agent to
   reduce by $1,000,000 or an integral multiple thereof or terminate entirely
   the Total Commitment, whereupon the Commitments of the Banks shall be
   reduced pro rata in accordance with their respective Commitment
   Percentages of the amount specified in such notice or, as the case may be,
   terminated.  The Agent will notify the Banks promptly after receiving any
   notice of the Borrowers delivered pursuant to this Section 2.2.

        (b)  No reduction or termination of the Commitments once made may be
   revoked; the portion of the Commitments reduced or terminated may not be
   reinstated; and amounts in respect of such reduced or terminated portion
   may not be reborrowed.

        (c) Unless a Default or Event of Default has occurred and is
   continuing, the Borrowers may request that the Total Commitment be
   increased by $40,000,000 hereunder, subject to the approval of the Agent,
   provided, however, that (i) any Bank which is a party to this Agreement
   prior to such increase may elect to fund its pro rata share of the
   increase, thereby increasing its Commitment hereunder, but no Bank shall
   be required to do so, (ii) in the event that it becomes necessary to
   include a new Bank to provide additional funding under this Section 2.2,
   such new Bank must be reasonably acceptable to the Agent and the
   Borrowers, and (iii) the Banks' Commitment Percentages shall be
   correspondingly adjusted, as necessary, to reflect any increase in the
   Total Commitment.

        Section 2.3.  The Notes. The Loans shall be evidenced by separate
   promissory notes of the Borrowers in substantially the form of Exhibit A
   hereto (each a "Note"), dated as of the Closing Date and completed with
   appropriate insertions.  One Note shall be payable to the order of each
   Bank in a principal amount equal to such Bank's Commitment or, if less,
   the outstanding amount of all Loans made by such Bank, plus interest
   accrued thereon, as set forth below.  The Borrowers irrevocably authorize
   each Bank to make or cause to be made, in connection with a Drawdown Date
   of any Loan or at the time of receipt of any payment of principal on such
   Bank's Note, an appropriate notation on such Bank's records reflecting the
   making of such Loan or the receipt of such payment (as the case may be). 
   The outstanding amount of the Loans set forth on such Bank's record shall
   be prima facie evidence of the principal amount thereof owing and unpaid
   to such Bank, but the failure to record, or any error in so recording, any
   such amount shall not limit or otherwise affect the obligations of the
   Borrowers hereunder or under any Note to make payments of principal of or
   interest on any Note when due.

   Section 2.4.  Interest on Loans.

        The outstanding principal amount of the Loans shall bear interest at
   the rate per annum equal to (a) the Base Rate, or (b) at the Borrowers'
   option as provided herein, the Eurodollar Rate plus the Applicable
   Eurodollar Margin.  Interest shall be payable (x) quarterly in arrears on
   the first Business Day of the next succeeding quarter, commencing April 1,
   1997, on Base Rate Loans, (y) on the last day of the applicable Interest
   Period, and if such Interest Period is longer than three (3) months, also
   on the last day of the third month following the commencement of such
   Interest Period, on Eurodollar Loans, and (z) on the Maturity Date for all
   Loans.

        Section 2.5.  Election of Eurodollar Rate; Notice of Election;
   Interest Periods; Minimum Amounts.

             (a)  At the Borrowers' option, so long as no Default or Event of
   Default has occurred and is then continuing, the Borrowers may (i) elect
   to convert any Base Rate Loan or a portion thereof to a Eurodollar Loan,
   (ii) at the time of any Loan and Letter of Credit Request, specify that
   such requested Loan shall be a Eurodollar Loan, or (iii) upon expiration
   of the applicable Interest Period, elect to maintain an existing
   Eurodollar Loan as such, provided that the Borrowers give notice to the
   Agent pursuant to Section 2.5(b) hereof.  Upon determining any Eurodollar
   Rate, the Agent shall forthwith provide notice thereof to the Borrowers
   and the Banks, and each such notice to the Borrowers and the Banks shall
   be considered prima facie correct and binding, absent manifest error.

             (b)  Three (3) Eurodollar Business Days prior to the making of
   any Eurodollar Loan or the conversion of any Base Rate Loan to a
   Eurodollar Loan, or, in the case of an outstanding Eurodollar Loan, the
   expiration date of the applicable Interest Period, the Borrowers shall
   give telephonic notice (confirmed by telecopy on the same Eurodollar
   Business Day) to the Agent not later than 11:00 a.m. (Boston time) of its
   election pursuant to Section 2.5(a).  Each such notice delivered to the
   Agent shall specify the aggregate principal amount of the Loans to be
   borrowed or maintained as or converted to Eurodollar Loans and the
   requested duration of the Interest Period that will be applicable to such
   Eurodollar Loan, and shall be irrevocable and binding upon the Borrowers. 
   If the Borrowers shall fail to give the Agent notice of their election
   hereunder together with all of the other information required by this
   Section 2.5(b) with respect to any Loan, such Loan shall be deemed a Base
   Rate Loan.  In the event that the Borrowers fail to provide any such
   notice with respect to the continuation of any Eurodollar Loan as such,
   then such Eurodollar Loan shall be automatically converted to a Base Rate
   Loan at the end of the then expiring Interest Period relating thereto.

             (c)  Notwithstanding anything herein to the contrary, the
   Borrowers may not specify an Interest Period that would extend beyond the
   Maturity Date.

             (d)  All Eurodollar Loans shall be in a minimum amount of not
   less than $1,000,000 and in integral multiples of $100,000 above such
   amount.  In no event shall the Borrowers have more than seven (7)
   different maturities of Eurodollar Loans outstanding at any time.

             (e)  All Base Rate Loans shall be in a minimum amount of not
   less than $500,000 and in integral multiples of $100,000 above such
   amount.

        Section 2.6.  Requests for Revolving Credit Loans.  The Borrowers
   shall give to the Agent written notice in the form of Exhibit B hereto (or
   telephonic notice confirmed by telecopy on the same Business Day in the
   form of Exhibit B hereto) of each Loan requested hereunder (a "Loan and
   Letter of Credit Request") not later than 11:00 a.m. Boston time
   (a) one (1) Business Day prior to the proposed Drawdown Date of any Base
   Rate Loan, or (b) three (3) Eurodollar Business Days prior to the proposed
   Drawdown Date of any Eurodollar Loan.  Each such notice shall be given by
   the Parent and shall specify the principal amount of the Loan requested
   and shall include a current Loan and Letter of Credit Request, reflecting
   the Maximum Drawing Amount of all Letters of Credit outstanding.  Each
   Loan and Letter of Credit Request shall be irrevocable and binding on the
   Borrowers and shall obligate the Borrowers to accept the Loan requested
   from the Banks on the proposed Drawdown Date.  Each of the representations
   and warranties made by or on behalf of any of the Borrowers to the Banks
   or the Agent in this Agreement or any other Loan Document shall be true
   and correct in all material respects when made and shall, for all purposes
   of this Agreement, be deemed to be repeated on and as of the date of the
   submission of any Loan and Letter of Credit Request and on and as of the
   Drawdown Date of such Loan or the date of issuance of such Letter of
   Credit (except to the extent of changes resulting from transactions
   contemplated or permitted by this Agreement and the other Loan Documents
   and changes occurring in the ordinary course of business that singly or in
   the aggregate are not materially adverse, or to the extent that such
   representations and warranties expressly relate to an earlier date).  The
   Agent shall promptly notify each Bank of each Loan and Letter of Credit
   Request received by the Agent.

        Section 2.7.  Funds for Loans.  

        (a)  Not later than 1:00 p.m. (Boston time) on the proposed Drawdown
   Date of any Loans, each of the Banks will make available to the Agent, at
   its Head Office, in immediately available funds, the amount of such Bank's
   Commitment Percentage of the amount of the requested Loans.  Upon receipt
   from each Bank of such amount, and upon receipt of the documents required
   by Section Section 9 and 10 and the satisfaction of the other conditions
   set forth therein, to the extent applicable, the Agent will make available
   to the Borrowers the aggregate amount of such Loans made available to the
   Agent by the Banks.  The failure or refusal of any Bank to make available
   to the Agent at the aforesaid time and place on any Drawdown Date the
   amount of its Commitment Percentage of the requested Loans shall not
   relieve any other Bank from its several obligation hereunder to make
   available to the Agent the amount of such other Bank's Commitment
   Percentage of any requested Loans.

        (b)  The Agent may, unless notified to the contrary by any Bank prior
   to a Drawdown Date, assume that such Bank has made available to the Agent
   on such Drawdown Date the amount of such Bank's Commitment Percentage of
   the Loans to be made on such Drawdown Date, and the Agent may (but it
   shall not be required to), in reliance upon such assumption, make
   available to the Borrowers a corresponding amount.  If any Bank makes
   available to the Agent such amount on a date after such Drawdown Date,
   such Bank shall pay to the Agent on demand an amount equal to the product
   of (i) the average computed for the period referred to in clause (iii)
   below, of the weighted average interest rate paid by the Agent for federal
   funds acquired by the Agent during each day included in such period, times
   (ii) the amount of such Bank's Commitment Percentage of such Loans, times
   (iii) a fraction, the numerator of which is the number of days that elapse
   from and including such Drawdown Date to the date on which the amount of
   such Bank's Commitment Percentage of such Loans shall become immediately
   available to the Agent, and the denominator of which is 365.  A statement
   of the Agent submitted to such Bank with respect to any amounts owing
   under this paragraph shall be prima facie evidence, absent manifest error,
   of the amount due and owing to the Agent by such Bank.  If the amount of
   such Bank's Commitment Percentage of such Loans is not made available to
   the Agent by such Bank within three (3) Business Days following such
   Drawdown Date, the Agent shall be entitled to recover such amount from the
   Borrowers on demand, with interest thereon at the rate per annum
   applicable to the Loans made on such Drawdown Date.

        Section 2.8.  Maturity of the Loans.  The Loans shall be due and
   payable on the Maturity Date.  The Borrowers promise to pay on the
   Maturity Date all Loans outstanding on such date, together with any and
   all accrued and unpaid interest thereon.

        Section 2.9.  Mandatory Repayments of the Loans.  If at any time the
   outstanding amount of the Loans plus the Maximum Drawing Amount of all
   outstanding Letters of Credit plus unpaid Reimbursement Obligations
   exceeds the Total Commitment, whether by reduction of the Total Commitment
   or otherwise, then the Borrowers shall immediately pay the amount of such
   excess to the Agent for application to the Loans, or if no Loans shall be
   outstanding, to be held by the Agent as collateral security for the
   Reimbursement Obligations, provided, however, that if the amount of cash
   collateral held by the Agent pursuant to this Section 2.9 exceeds the
   amount of the Obligations the Agent shall return such excess to the
   Borrowers. 

        Section 2.10.  Optional Prepayments or Repayments of Loans.  The
   Borrowers shall have the right, at their election, to repay or prepay the
   outstanding amount of the Loans, as a whole or in part, at any time
   without penalty or premium.  The Borrowers shall give the Agent, no later
   than 11:00 a.m. (Boston time) on the Business Day of such proposed
   prepayment or repayment, written notice (or telephonic notice confirmed in
   writing) of any proposed prepayment or repayment pursuant to this Section
   2.10, specifying the proposed date of prepayment or repayment of Loans and
   the principal amount to be paid; provided that the Borrowers may not make
   any prepayment of any Eurodollar Loan on a date other than the last day of
   the applicable Interest Period.

        Section 3.  LETTERS OF CREDIT.

        Section 3.1.  Letter of Credit Commitments.

             (a)  Subject to the terms and conditions hereof and the
   execution and receipt of a Loan and Letter of Credit Request reflecting
   the Maximum Drawing Amount of all Letters of Credit (including the
   requested Letter of Credit) and a Letter of Credit Application, the Agent,
   on behalf of the Banks and in reliance upon the agreement of the Banks set
   forth in Section 3.1(b) and upon the representations and warranties of the
   Borrowers contained herein, agrees to issue standby letters of credit, in
   such form as may be requested from time to time by the Borrowers and
   agreed to by the Agent; provided, however, that, after giving effect to
   such request, the aggregate Maximum Drawing Amount of all letters of
   credit issued at any time under this Section 3.1(a) (the "Letters of
   Credit") shall not exceed $30,000,000, and no Letter of Credit shall have
   an expiration date later than the earlier of (i) one (1) year after the
   date of issuance of the Letter of Credit (which may incorporate automatic
   renewals for periods of up to one (1) year, provided that the Agent may,
   upon 30 days' notice to the beneficiary, cancel such Letter of Credit
   which has been renewed beyond its initial one (1) year term), or (ii)
   thirty (30) days prior to the Maturity Date. 

             (b)  Each Bank severally agrees that it shall be absolutely
   liable, without regard to the occurrence of any Default or Event of
   Default or any other condition precedent whatsoever, to the extent of such
   Bank's Commitment Percentage thereof, to reimburse the Agent on demand for
   the amount of each draft paid by the Agent under each Letter of Credit to
   the extent that such amount is not reimbursed by the Borrowers pursuant to
   Section 3.2 (such agreement for a Bank being called herein the "Letter of
   Credit Participation" of such Bank).

             (c)  Each such payment made by a Bank shall be treated as the
   purchase by such Bank of a participating interest in the Borrowers'
   Reimbursement Obligation under Section 3.2 in an amount equal to such
   payment.  Each Bank shall share in accordance with its participating
   interest in any interest which accrues pursuant to Section 3.2.

        Section 3.2.  Reimbursement Obligation of the Borrowers.  In order to
   induce the Agent to issue, extend and renew each Letter of Credit and the
   Banks to participate therein, the Borrowers hereby agree to reimburse or
   pay to the Agent with respect to each Letter of Credit issued, extended or
   renewed by the Agent hereunder as follows:

             (a)  on each date that any draft presented under any Letter of
   Credit is honored by the Agent or the Agent otherwise makes payment with
   respect thereto, (i) the amount paid by the Agent under or with respect to
   such Letter of Credit, and (ii) the amount of any taxes, fees, charges or
   other costs and expenses whatsoever incurred by the Agent or any Bank in
   connection with any payment made by the Agent or any Bank under, or with
   respect to, such Letter of Credit; and 

             (b)  upon the Maturity Date or the acceleration of the
   Reimbursement Obligations with respect to all Letters of Credit in
   accordance with Section 12, an amount equal to the then Maximum Drawing
   Amount of all Letters of Credit, which amount shall be held by the Agent
   for the benefit of the Banks and the Agent as cash collateral for all
   Reimbursement Obligations.

        Each such payment shall be made to the Agent at the Agent's Head
   Office in immediately available funds.  Interest on any and all amounts
   remaining unpaid by the Borrowers under this Section 3.2 at any time from
   the date such amounts become due and payable (whether as stated in this
   Section 3.2, by acceleration or otherwise) until payment in full (whether
   before or after judgment) shall be payable to the Agent on demand at the
   rate specified in Section 4.6 for overdue amounts.

        Section 3.3.  Letter of Credit Payments.  If any draft shall be
   presented or other demand for payment shall be made under any Letter of
   Credit, the Agent shall notify the Borrowers of the date and amount of the
   draft presented or demand for payment and of the date and time when it
   expects to pay such draft or honor such demand for payment.  On the date
   that such draft is paid or other payment is made by the Agent, the Agent
   shall promptly notify the Banks of the amount of any unpaid Reimbursement
   Obligation.  No later than 3:00 p.m. (Boston time) on the Business Day
   next following the receipt of such notice, each Bank shall make available
   to the Agent, at the Agent's Head Office, in immediately available funds,
   such Bank's Commitment Percentage of such Reimbursement Obligation,
   together with an amount equal to the product of (a) the weighted average,
   computed for the period referred to in clause (c) below, of the interest
   rate paid by the Agent for federal funds acquired by the Agent during each
   day included in such period, times (b) the amount equal to such Bank's
   Commitment Percentage of such unpaid Reimbursement Obligation, times (c) a
   fraction, the numerator of which is the number of days that have elapsed
   from and including the date the Agent paid the draft presented for honor
   or otherwise made payment until the date on which such Bank's Commitment
   Percentage of such unpaid Reimbursement Obligation shall become
   immediately available to the Agent, and the denominator of which is 365. 
   The responsibility of the Agent to the Borrowers and the Banks shall be
   only to determine that the documents (including each draft) delivered
   under each Letter of Credit in connection with such presentment shall be
   in conformity in all material respects with such Letter of Credit.

        Section 3.4.  Obligations Absolute.     The Borrowers' obligations
   under this Section 3 shall be absolute and unconditional under any and all
   circumstances and irrespective of the occurrence of any Default or Event
   of Default or any condition precedent whatsoever or any setoff,
   counterclaim or defense to payment which the Borrowers may have or have
   had against the Agent, any Bank or any beneficiary of a Letter of Credit. 
   Subject to the obligations of the Banks pursuant to Article V of the
   Uniform Commercial Code, the Borrowers further agree with the Agent and
   the Banks that the Agent and the Banks shall not be responsible for, and
   the Borrowers' Reimbursement Obligations under Section 3.2 shall not be
   affected by, among other things, the validity or genuineness of documents
   or of any endorsements thereon, even if such documents should in fact
   prove to be in any or all respects invalid, fraudulent or forged, or any
   dispute between or among the Borrowers, the beneficiary of any Letter of
   Credit or any financing institution or other party to which any Letter of
   Credit may be transferred or any claims or defenses whatsoever of the
   Borrowers against the beneficiary of any Letter of Credit or any such
   transferee.  The Agent and the Banks shall not be liable for any error,
   omission, interruption or delay in transmission, dispatch or delivery of
   any message or advice, however transmitted, in connection with any Letter
   of Credit.  The Borrowers agree that any action taken or omitted by the
   Agent or any Bank under or in connection with each Letter of Credit and
   the related drafts and documents, if done in good faith, shall be binding
   upon the Borrowers and shall not result in any liability on the part of
   the Agent or any Bank to the Borrowers.

        Section 3.5.  Reliance by Agent.  To the extent not inconsistent with
   Section 3.4, the Agent shall be entitled to rely, and shall be fully
   protected in relying upon, any Letter of Credit, draft, writing,
   resolution, notice, consent, certificate, affidavit, letter, cablegram,
   telegram, telecopy, telex or teletype message, statement, order or other
   document believed by it to be genuine and correct and to have been signed,
   sent or made by the proper Person or Persons and upon advice and
   statements of legal counsel, independent accountants and other experts
   selected by the Agent.

        Section 4.     FEES, PAYMENTS, AND COMPUTATIONS; JOINT AND SEVERAL
                       LIABILITY.

        Section 4.1.  Fees.

             (a)  Commitment Fee.  The Borrowers agree to pay to the Agent,
   for the accounts of the Banks, a fee (the "Commitment Fee") equal to the
   Applicable Commitment Rate multiplied by the amount of the unused portion
   of the Total Commitment during each calendar quarter or portion thereof
   from the Closing Date to the Maturity Date (or to the date of termination
   in full of the Total Commitment, if earlier).  The Commitment Fee shall be
   payable quarterly in arrears on the first day of each calendar quarter for
   the immediately preceding calendar quarter commencing on April 1, 1997,
   with a final payment on the Maturity Date.

             (b)  Letter of Credit Fees.  The Borrowers shall pay in advance
   on the date of issuance of each Letter of Credit an issuance fee to the
   Agent equal to one eighth of one percent (1/8%) per annum (the "Issuance
   Fee") on the Maximum Drawing Amount of each Letter of Credit, plus a fee
   (the "Letter of Credit Fee") equal to (a) the Applicable L/C Margin
   multiplied by the Maximum Drawing Amount of each outstanding Financial
   Letter of Credit, or (b) the Applicable L/C Margin minus 0.50%, multiplied
   by the Maximum Drawing Amount of all other Letters of Credit, provided,
   however, that the Letter of Credit Fee with respect to non-Financial
   Letters of Credit shall not be less than 0.50%, such Letter of Credit Fee
   (but not the Issuance Fee) shall be paid quarterly in advance on the first
   Business Day of each fiscal quarter, and shall be for the accounts of the
   Banks in accordance with their respective Commitment Percentages.  In
   addition to the Issuance Fee and the Letter of Credit Fee, the Borrowers
   shall pay to the Agent, for its own account, all related customary
   administrative fees in accordance with customary practice.

             (c)  Closing Fees.  The Borrowers shall pay at closing (i) each
   of FNBB and LaSalle a fee equal to 0.25% of the amount by which such
   Bank's Commitment hereunder exceeds its Commitment under the Original
   Credit Agreement, (ii) Bank One a fee equal to 0.25% of the amount by
   which its Commitment hereunder exceeds the Commitment of Bank One, Texas,
   National Association under the Original Credit Agreement and (iii) BAI a
   fee in the amount of 0.25% of its Commitment.

        Section 4.2.  Payments.

             (a)  All payments of principal, interest, Reimbursement
   Obligations, fees and any other amounts due hereunder or under any of the
   other Loan Documents shall be made to the Agent, for the respective
   accounts of the Banks and the Agent, to be received at the Agent's Head
   Office in immediately available funds by 12:00 p.m. (Boston time) on any
   due date.

             (b)  All payments by the Borrowers hereunder and under any of
   the other Loan Documents shall be made without setoff or counterclaim and
   free and clear of and without deduction for any taxes, levies, imposts,
   duties, charges, fees, deductions, withholdings, compulsory loans,
   restrictions or conditions of any nature now or hereafter imposed or
   levied by any jurisdiction or any political subdivision thereof or taxing
   or other authority therein unless the Borrowers are compelled by law to
   make such deduction or withholding.  If any such obligation is imposed
   upon the Borrowers with respect to any amount payable by them hereunder or
   under any of the other Loan Documents, the Borrowers will pay to the
   Agent, for the account of the Banks or (as the case may be) the Agent, on
   the date on which such amount is due and payable hereunder or under such
   other Loan Document, such additional amount in Dollars as shall be
   necessary to enable the Banks or the Agent to receive the same net amount
   which the Banks or the Agent would have received on such due date had no
   such obligation been imposed upon the Borrowers.  In the event that the
   Borrowers are required to make such deduction or withholding as a result
   of the fact that a Bank is organized outside of the United States, such
   Bank shall use its reasonable best efforts to transfer its Loans to an
   affiliate organized within the United States if such transfer would have
   no adverse effect on such Bank or the Loans.  The Borrowers will deliver
   promptly to the Bank certificates or other valid vouchers for all taxes or
   other charges deducted from or paid with respect to payments made by the
   Borrowers hereunder or under such other Loan Document.

        Section 4.3.  Computations.   All computations of interest on Base
   Rate Loans and of Commitment Fees, Letter of Credit Fees or other fees
   shall, unless otherwise expressly provided herein, be based on a 365-day
   year (or 366-day year, as applicable) and paid for the actual number of
   days elapsed.  All computations of interest on Eurodollar Loans shall,
   unless otherwise expressly provided herein, be based on a 360-day year and
   paid for the actual number of days elapsed.  Whenever a payment hereunder
   or under any of the other Loan Documents becomes due on a day that is not
   a Business Day, the due date for such payment shall be extended to the
   next succeeding Business Day, and interest shall accrue during such
   extension.

        Section 4.4. Capital Adequacy.  If any present or future law,
   governmental rule, regulation, policy, guideline or directive (whether or
   not having the force of law) or the interpretation thereof by a court or
   governmental authority with appropriate jurisdiction affects the amount of
   capital required or expected to be maintained by any Bank or the Agent or
   any corporation controlling such Bank or the Agent, and such Bank or the
   Agent determines that the amount of capital required to be maintained by
   it is increased by or based upon the existence of such Bank's or the
   Agent's Loans, Letter of Credit Participations or Letters of Credit, or
   commitment with respect thereto, then such Bank or the Agent may notify
   the Borrowers of such fact.  To the extent that the costs of such
   increased capital requirements are not reflected in the Base Rate (if
   relating to Base Rate Loans), the Borrowers and such Bank or (as the case
   may be) the Agent shall thereafter attempt to negotiate in good faith,
   within thirty (30) days of the day on which the Borrowers receive such
   notice, an adjustment payable hereunder that will adequately compensate
   such Bank or the Agent in light of these circumstances.  If the Borrowers
   and such Bank or the Agent are unable to agree to such adjustment within
   thirty (30) days of the date on which the Borrowers receive such notice,
   then commencing on the date of such notice (but not earlier than the
   effective date of any such increased capital requirement), the fees
   payable hereunder shall increase by an amount that will, in such Bank's or
   the Agent's reasonable determination, provide adequate compensation.  Each
   Bank and the Agent shall allocate such cost increases among its customers
   in good faith and on an equitable basis.

        Section 4.5.  Certificate.     A certificate setting forth any
   additional amounts payable pursuant to Section 4.4 and a reasonable
   explanation of such amounts which are due, submitted by any Bank or the
   Agent to the Borrowers, shall be conclusive, absent manifest error, that
   such amounts are due and owing.

        Section 4.6.  Interest on Overdue Amounts.   Overdue principal and
   (to the extent permitted by applicable law) interest on the Loans and all
   other overdue amounts payable hereunder or under any of the other Loan
   Documents shall bear interest compounded monthly and payable on demand at
   a rate per annum equal to the Base Rate plus two (2) percentage points
   until such amount shall be paid in full (after, as well as before,
   judgment).

        Section 4.7.  Interest Limitation.      Notwithstanding any other
   term of this Agreement or any Note or any other document referred to
   herein or therein, the maximum amount of interest which may be charged to
   or collected from any person liable hereunder or under any Note by any
   Bank shall be absolutely limited to, and shall in no event exceed, the
   maximum amount of interest which could lawfully be charged or collected
   under applicable law (including, to the extent applicable, the provisions
   of Section 5197 of the Revised Statutes of the United States of America,
   as amended, 12 U.S.C. Section 85, as amended), so that the maximum of all
   amounts constituting interest under applicable law, howsoever computed,
   shall never exceed as to any Person liable therefor such lawful maximum,
   and any term of this Agreement, the Notes, the Letter of Credit
   Applications, or any other document referred to herein or therein which
   could be construed as providing for interest in excess of such lawful
   maximum shall be and hereby is made expressly subject to and modified by
   the provisions of this paragraph.

        Section 4.8.  Eurodollar Indemnity.     The Borrowers agree to
   indemnify the Banks and the Agent and to hold them harmless from and
   against any loss, cost or expenses (including loss of anticipated profits)
   that the Banks and the Agent may sustain or incur as a consequence of (a)
   default by the Borrowers in payment of the principal amount of or any
   interest on any Eurodollar Loans as and when due and payable, including
   any such loss or expense arising from interest or fees payable by any Bank
   or the Agent to lenders of funds obtained by it in order to maintain its
   Eurodollar Loans, or (b) default by the Borrowers in making a borrowing or
   conversion after the Borrowers have given (or are deemed to have given)
   notice pursuant to Section 2.5 or Section 2.6, the making of any payment
   of a Eurodollar Loan or the making of any conversion of any such
   Eurodollar Loan to a Base Rate Loan on a day that is not the last day of
   the applicable Interest Period with respect thereto, including interest or
   fees payable by any Bank to lenders of funds obtained by it in order to
   maintain any such Loans.

        Section 4.9.  Illegality; Inability to Determine Eurodollar Rate.
   Notwithstanding any other provision of this Agreement, if (a) the
   introduction of, any change in, or any change in the interpretation of,
   any law or regulation applicable to the Agent or any Bank shall make it
   unlawful, or any central bank or other governmental authority having
   jurisdiction thereof shall assert that it is unlawful, for any Bank or the
   Agent to perform its obligations in respect of any Eurodollar Loans, or
   (b) if the Banks or the Agent shall reasonably determine with respect to
   Eurodollar Loans that (i) by reason of circumstances affecting any
   Eurodollar interbank market, adequate and reasonable methods do not exist
   for ascertaining the Eurodollar Rate which would otherwise be applicable
   during any Interest Period, or (ii) deposits of Dollars in the relevant
   amount for the relevant Interest Period are not available to the Banks or
   the Agent in any Eurodollar interbank market, or (iii) the Eurodollar Rate
   does not or will not accurately reflect the cost to the Banks or the Agent
   of obtaining or maintaining the applicable Eurodollar Loans  during any
   Interest Period, then the Banks or the Agent shall promptly give
   telephonic, telex or cable notice of such determination to the Borrowers
   (which notice shall be conclusive and binding upon the Borrowers).  Upon
   such notification by the Banks or the Agent, the obligation of the Banks
   or the Agent to make Eurodollar Loans shall be suspended until the Banks
   or the Agent determine that such circumstances no longer exist, and the
   outstanding Eurodollar Loans shall continue to bear interest at the
   applicable rate based on the Eurodollar Rate until the end of the
   applicable Interest Period, and thereafter shall be deemed converted to
   Base Rate Loans in equal principal amounts.

        Section 4.10.  Additional Costs, Etc.   If any present or future
   applicable law, which expression, as used herein, includes statutes, rules
   and regulations thereunder and interpretations thereof by any competent
   court or by any governmental or other regulatory body or official charged
   with the administration or the interpretation thereof and requests,
   directives, instructions and notices at any time or from time to time
   hereafter made upon or otherwise issued to any Bank by any central bank or
   other fiscal, monetary or other authority (whether or not having the force
   of law), shall impose on any Bank any tax, levy, impost, duty, charge
   fees, deduction or withholdings of any nature or requirements with respect
   to this Agreement, the other Loan Documents, the Loans, such Bank's
   Commitment, the Letters of Credit or any class of loans or commitments or
   letters of credit of which any of the Loans, the Commitment or the Letters
   of Credit forms a part, and the result of any of the foregoing is:

             (i)  to increase the cost to such Bank of making, funding,
   issuing, renewing, extending or maintaining the Loans, such Bank's
   Commitment, or the Letters of Credit; or


             (ii) to reduce the amount of principal, interest or other amount
   payable to such Bank hereunder on account of such Bank's Commitment, the
   Loans, or drawings under the Letters of Credit, or
       
             (iii)     to require such Bank to make any payment or to forego
   any interest or other sum payable hereunder, the amount of which payment
   or foregone interest or other sum is calculated by reference to the gross
   amount of any sum receivable or deemed received by such Bank from the
   Borrowers hereunder,
   then, and in each such case, the Borrowers will, upon demand made by such
   Bank at any time and from time to time and as often as the occasion
   therefor may arise, pay to such Bank such additional amounts as will be
   sufficient to compensate such Bank for such additional cost, reduction,
   payment or foregone interest or other sum (after such Bank shall have
   allocated the same fairly and equitably among all customers of any class
   generally affected thereby).

        Section 4.11.  Concerning Joint and Several Liability of the
   Borrowers.

             (a)  Each of the Borrowers is accepting joint and several
   liability hereunder and under the other Loan Documents in consideration of
   the financial accommodations to be provided by the Banks under this
   Agreement, for the mutual benefit, directly and indirectly, of each of the
   Borrowers and in consideration of the undertakings of each other Borrower
   to accept joint and several liability for the Obligations.

             (b)  Each of the Borrowers, jointly and severally, hereby
   irrevocably and unconditionally accepts, not merely as a surety but also
   as a co-debtor, joint and several liability with the other Borrowers with
   respect to the payment and performance of all of the Obligations
   (including, without limitation, any Obligations arising under this Section
   4.11), it being the intention of the parties hereto that all of the
   Obligations shall be the joint and several Obligations of each of the
   Borrowers without preferences or distinction among them.

             (c)  If and to the extent that any of the Borrowers shall fail
   to make any payment with respect to any of the Obligations as and when due
   or to perform any of the Obligations in accordance with the terms thereof,
   then in each such event the other Borrowers will make such payment with
   respect to, or perform, such Obligation.

             (d)  The Obligations of each of the Borrowers under the
   provisions of this Section 4.11 constitute full recourse Obligations of
   each of the Borrowers enforceable against each such corporation to the
   full extent of its properties and assets, irrespective of the validity,
   regularity or enforceability of this Agreement or any other circumstance
   whatsoever.

             (e)  Except as otherwise expressly provided in this Agreement,
   each of the Borrowers hereby waives notice of acceptance of its joint and
   several liability, notice of any Loans made under this Agreement, notice
   of any action at any time taken or omitted by the Banks under or in
   respect of any of the Obligations, and, generally, to the extent permitted
   by applicable law, all demands, notices and other formalities of every
   kind in connection with this Agreement.  Each of the Borrowers hereby
   assents to, and waives notice of, any extension or postponement of the
   time for the payment of any of the Obligations, the acceptance of any
   payment of any of the Obligations, the acceptance of any partial payment
   thereon, any waiver, consent or other action or acquiescence by the Banks
   at any time or times in respect of any default by any of the Borrowers in
   the performance or satisfaction of any term, covenant, condition or
   provision of this Agreement, any and all other indulgences whatsoever by
   the Banks in respect of any of the Obligations, and the taking, addition,
   substitution or release, in whole or in part, at any time or times, of any
   security for any of the Obligations or the addition, substitution or
   release, in whole or in part, of any of the Borrowers.  Without limiting
   the generality of the foregoing, each of the Borrowers assents to any
   other action or delay in acting or failure to act on the part of the Banks
   with respect to the failure by any of the Borrowers to comply with any of
   its respective Obligations, including, without limitation, any failure
   strictly or diligently to assert any right or to pursue any remedy or to
   comply fully with applicable laws or regulations thereunder, which might,
   but for the provisions of this Section 4.11, afford grounds for
   terminating, discharging or relieving any of the Borrowers, in whole or in
   part, from any of its Obligations under this Section 4.11, it being the
   intention of each of the Borrowers that, so long as any of the Obligations
   hereunder remain unsatisfied, the Obligations of such Borrowers under this
   Section 4.11 shall not be discharged except by performance and then only
   to the extent of such performance.  The Obligations of each of the
   Borrowers under this Section 4.11 shall not be diminished or rendered
   unenforceable by any winding up, reorganization, arrangement, liquidation,
   re-construction or similar proceeding with respect to any of the Borrowers
   or the Banks.  The joint and several liability of the Borrowers hereunder
   shall continue in full force and effect notwithstanding any absorption,
   merger, amalgamation or any other change whatsoever in the name,
   membership, constitution or place of formation of any of the Borrowers or
   the Banks.

             (f)  The provisions of this Section 4.11 are made for the
   benefit of the Banks and their successors and assigns, and may be enforced
   in good faith by them from time to time against any or all of the
   Borrowers as often as the occasion therefor may arise and without
   requirement on the part of the Banks first to marshal any of their claims
   or to exercise any of their rights against any other Borrower or to
   exhaust any remedies available to them against any other Borrower or to
   resort to any other source or means of obtaining payment of any of the
   Obligations hereunder or to elect any other remedy.  The provisions of
   this Section 4.11 shall remain in effect until all of the Obligations
   shall have been paid in full or otherwise fully satisfied.  If at any
   time, any payment, or any part thereof, made in respect of any of the
   Obligations, is rescinded or must otherwise be restored or returned by the
   Banks upon the insolvency, bankruptcy or reorganization of any of the
   Borrowers, or otherwise, the provisions of this Section 4.11 will
   forthwith be reinstated in effect, as though such payment had not been
   made.

        Section 4.12.  New Borrowers.  Any newly-created or acquired
   Subsidiaries shall become Borrowers hereunder by signing Notes, entering
   into an amendment to this Agreement with the other parties hereto
   providing that such Subsidiary shall become a Borrower hereunder, and
   providing such other documentation as the Banks or the Agent may
   reasonably request, including, without limitation, documentation with
   respect to conditions specified in Section 9 hereof.  In such event, the
   Agent is hereby authorized by the parties to amend Schedule 1 hereto to
   include such Subsidiary as a Borrower hereunder.  The Parent hereby agrees
   to pledge all of the stock of such Subsidiary to the Agent for the benefit
   of the Banks pursuant to the terms of the Stock Pledge Agreement.  

        Section 5.  REPRESENTATIONS AND WARRANTIES.  The Borrowers jointly
   and severally represent and warrant to the Banks that on and as of the
   date of this Agreement (any disclosure on a schedule pursuant to this
   Section 5 shall be deemed to apply to all relevant representations and
   warranties, regardless of whether such schedule is referenced in each
   relevant representation):
        Section 5.1.  Corporate Authority.

        (a)  Incorporation; Good Standing.  Each of the Borrowers (i) is a
   corporation duly organized, validly existing and in good standing or in
   current status under the laws of its respective state of incorporation,
   (ii) has all requisite corporate power to own its property and conduct its
   business as now conducted and as presently contemplated, and (iii) is in
   good standing as a foreign corporation and is duly authorized to do
   business in each jurisdiction in which its property or business as
   presently conducted or contemplated makes such qualification necessary
   except where a failure to be so qualified would not have a material
   adverse effect on the business, assets or financial condition of such
   Borrower.

        (b)  Authorization.  The execution, delivery and performance of its
   Loan Documents and the transactions contemplated hereby and thereby (i)
   are within the corporate authority of each of the Borrowers, (ii) have
   been duly authorized by all necessary corporate proceedings, (iii) do not
   conflict with or result in any material breach or contravention of any
   provision of law, statute, rule or regulation to which any of the
   Borrowers is subject or any judgment, order, writ, injunction, license or
   permit applicable to any of the Borrowers so as to materially adversely
   affect the assets, business or any activity of any of the Borrowers, and
   (iv) do not conflict with any provision of the corporate charter or bylaws
   of any Borrower or any agreement or other instrument binding upon any
   Borrower. 

        (c)  Enforceability.  The execution, delivery and performance of the
   Loan Documents will result in valid and legally binding obligations of the
   Borrowers enforceable against each in accordance with the respective terms
   and provisions hereof and thereof, except as enforceability is limited by
   bankruptcy, insolvency, reorganization, moratorium or other laws relating
   to or affecting generally the enforcement of creditors' rights and except
   to the extent that availability of the remedy of specific performance or
   injunctive relief is subject to the discretion of the court before which
   any proceeding therefor may be brought.

        Section 5.2.  Governmental Approvals.  The execution, delivery and
   performance by the Borrowers of the Loan Documents and the transactions
   contemplated hereby and thereby do not require any approval or consent of,
   or filing with, any governmental agency or authority other than those
   already obtained.

        Section 5.3.  Title to Properties; Leases.  The Borrowers own all of
   the assets reflected in the consolidated balance sheets as at the Balance
   Sheet Date or acquired since that date (except property and assets sold or
   otherwise disposed of in the ordinary course of business since that date),
   subject to no mortgages, capitalized leases, conditional sales agreements,
   title retention agreements, liens or other encumbrances except Permitted
   Liens.

        Section 5.4.  Financial Statements; Solvency.

             (a)  There has been furnished to the Banks (i) audited
   consolidated financial statements of the Borrowers dated the Balance Sheet
   Date, certified by an independent accounting firm of national standing
   acceptable to the Banks (the "Accountants") and (ii) unaudited
   consolidated financial statements of the Borrowers dated the Company
   Balance Sheet Date.  Said financial statements have been prepared in
   accordance with GAAP (but, in the case of any such financial statements
   which are unaudited, only to the extent that GAAP is applicable to interim
   unaudited reports), fairly present in all material respects the financial
   condition of the Borrowers, on a consolidated basis, as at the close of
   business on the date thereof and the results of operations for the period
   then ended.  There are no contingent liabilities of the Borrowers as of
   such date involving material amounts known to the officers of the
   Borrowers which have not been disclosed in said balance sheets and the
   related notes thereto, as the case may be.

             (b)  The Borrowers (both before and after giving effect to the
   transactions contemplated by this Agreement) are solvent (i.e., they have
   assets having a fair value in excess of the amount required to pay their
   probable liabilities on their existing debts as they become absolute and
   matured) and have, and expect to have, the ability to pay their debts from
   time to time incurred in connection therewith as such debts mature.

        Section 5.5.  No Material Changes, Etc.  Since the Company Balance
   Sheet Date, there have occurred no material adverse changes in the
   financial condition or business of the Borrowers as shown on or reflected
   in the consolidated balance sheet of the Borrowers as at the Company
   Balance Sheet Date, or the consolidated statement of income for the fiscal
   year then ended other than changes in the ordinary course of business
   which have not had any material adverse effect either individually or in
   the aggregate on the business or financial condition of the Parent or the
   Borrowers.  Since the Company Balance Sheet Date, no Borrower has made any
   Distribution other than to the Parent.

        Section 5.6.  Permits, Franchises, Patents, Copyrights, Etc.  Each of
   the Borrowers possesses all franchises, patents, copyrights, trademarks,
   trade names, licenses and permits, and rights in respect of the foregoing,
   adequate for the conduct of its business substantially as now conducted
   without known conflict with any rights of others.

        Section 5.7.  Litigation.  Except as shown on Schedules 5.7 and 5.16
   hereto, there are no actions, suits, proceedings or investigations of any
   kind pending or, to the knowledge of the Borrowers, threatened against any
   Borrower before any court, tribunal or administrative agency or board
   which, if adversely determined, might, either in any case or in the
   aggregate, materially adversely affect the properties, assets, financial
   condition or business of the Borrowers, considered as a whole, or
   materially impair the right of the Borrowers, considered as a whole, to
   carry on business substantially as now conducted, or result in any
   substantial liability not adequately covered by insurance, or for which
   adequate reserves are not maintained on the consolidated balance sheet or
   which question the validity of any of the Loan Documents or any action
   taken or to be taken pursuant hereto or thereto.

        Section 5.8.  No Materially Adverse Contracts, Etc.  None of the
   Borrowers is subject to any charter, corporate or other legal restriction,
   or any judgment, decree, order, rule or regulation which in the judgment
   of the Borrowers' officers has or is expected in the future to have a
   materially adverse effect on the business, assets or financial condition
   of the Borrowers as a whole.  None of the Borrowers is a party to any
   contract or agreement which in the judgment of the Borrowers' officers has
   or is expected to have any materially adverse effect on the business of
   the Borrowers as a whole, except as otherwise reflected in adequate
   reserves.

        Section 5.9.  Compliance With Other Instruments, Laws, Etc.  None of
   the Borrowers is violating any provision of its charter documents or by-
   laws or any agreement or instrument by which any of them  may be subject
   or by which any of them or any of their properties may be bound or any
   decree, order, judgment, or any statute, license, rule or regulation, in a
   manner which could result in the imposition of substantial penalties or
   materially and adversely affect the financial condition, properties or
   business of any of the Borrowers.

        Section 5.10.  Tax Status.  The Borrowers have made or filed all
   federal and state income and all other tax returns, reports and
   declarations required by any jurisdiction to which any of them is subject
   (unless and only to the extent that any Borrower has set aside on its
   books provisions reasonably adequate for the payment of all unpaid and
   unreported taxes); and have paid all taxes and other governmental
   assessments and charges that are material in amount, shown or determined
   to be due on such returns, reports and declarations, except those being
   contested in good faith; and have set aside on their books provisions
   reasonably adequate for the payment of all taxes for periods subsequent to
   the periods to which such returns, reports or declarations apply.  There
   are no unpaid taxes in any material amount claimed to be due by the taxing
   authority of any jurisdiction, and the officers of the Borrowers know of
   no basis for any such claim.

        Section 5.11.  No Event of Default.  No Default or Event of Default
   has occurred and is continuing as of the date of this Agreement.

        Section 5.12.  Holding Company and Investment Company Acts.  None of
   the Borrowers is a "holding company," or a "subsidiary company" of a
   "holding company," or an "affiliate" of a "holding company," as such terms
   are defined in the Public Utility Holding Company Act of 1935; nor is any
   of them a "registered investment company," or an "affiliated company" or a
   "principal underwriter" of a "registered investment company," as such
   terms are defined in the Investment Company Act of 1940, as amended.

        Section 5.13.  Absence of Financing Statements, Etc.  Except as
   contemplated by Section 7.2 of this Agreement, there is no financing
   statement, security agreement, chattel mortgage, real estate mortgage or
   other document filed or recorded with any filing records, registry, or
   other public office, which purports to cover, affect or give notice of any
   present or possible future lien on, or security interest in, any assets or
   property of any of the Borrowers or rights thereunder, other than certain
   Liens granted pursuant to the Original Credit Agreement, which are to be
   released no later than June 26, 1997.

        Section 5.14.  Employee Benefit Plans.

        (a)  In General.  Each Employee Benefit Plan has been maintained and
   operated in compliance in all material respects with the provisions of
   ERISA and, to the extent applicable, the Code, including but not limited
   to the provisions thereunder respecting prohibited transactions.

        (b)  Terminability of Welfare Plans.  Under each Employee Benefit
   Plan which is an employee welfare benefit plan within the meaning of
   Section 3(1) or Section 3(2)(B) of ERISA, no benefits are due unless the
   event giving rise to the benefit entitlement occurs prior to plan
   termination (except as required by Title I, part 6 of ERISA.)  Each
   Borrower or ERISA Affiliate, as appropriate, may terminate each such Plan
   at any time (or at any time subsequent to the expiration of any applicable
   bargaining agreement) in the discretion of such Borrower or ERISA
   Affiliate without liability to any Person.

        (c)  Guaranteed Pension Plans.  None of the Borrowers is a sponsor
   of, or contributor to, a Guaranteed Pension Plan.

        (d)  Multiemployer Plans.  No Borrower, nor any ERISA Affiliate has
   incurred any material liability (including secondary liability) to any
   Multiemployer Plan as a result of a complete or partial withdrawal from
   such Multiemployer Plan under Section 4201 of ERISA or as a result of a
   sale of assets described in Section 4204 of ERISA.  No Borrower, nor any
   ERISA Affiliate has been notified that any Multiemployer Plan is in
   reorganization or is insolvent under and within the meaning of Section
   4241 or Section 4245 of ERISA or that any Multiemployer Plan intends to
   terminate or has been terminated under Section 4041A of ERISA.

        Section 5.15.  Use of Proceeds.  The proceeds of the Loans shall be
   used as follows:  (a) to repay the existing Indebtedness of the Borrowers;
   (b) for general corporate purposes; (c) for acquisitions permitted
   pursuant to Section 7.4 hereof; and (d) for working capital purposes.  No
   proceeds of the Loans shall be used in any way that will violate
   Regulations G, T, U or X of the Board of Governors of the Federal Reserve
   System.

        Section 5.16.  Environmental Compliance.  The Borrowers have taken
   all necessary steps to investigate the past and present condition and
   usage of the Real Properties and the operations conducted thereon and,
   based upon such diligent investigation, have determined that, except as
   shown on Schedule 5.16:

        (a)  None of the Borrowers, nor any operator of their properties, is
   in violation, or alleged violation, of any judgment, decree, order, law,
   permit, license, rule or regulation pertaining to environmental matters,
   including without limitation, those arising under RCRA, CERCLA, the
   Superfund Amendments and Reauthorization Act of 1986, the Federal Clean
   Water Act, the Federal Clean Air Act, the Toxic Substances Control Act, or
   any state or local statute, regulation, ordinance, order or decree
   relating to health, safety or the environment (the "Environmental Laws"),
   which violation would have a material adverse effect on the business,
   assets or financial condition of the Borrowers on a consolidated basis.

        (b)  None of the Borrowers has received notice from any third party,
   including, without limitation:  any federal, state or local governmental
   authority, (i) that any one of them has been identified by the United
   States Environmental Protection Agency ("EPA") as a potentially
   responsible party under CERCLA with respect to a site listed on the
   National Priorities List, 40 C.F.R. Part 300 Appendix B; (ii) that any
   hazardous waste, as defined by 42 U.S.C. Section 6903(5), any hazardous
   substances as defined by 42 U.S.C. Section 9601(14), any pollutant or
   contaminant as defined by 42 U.S.C. Section 9601(33) or any toxic
   substance, oil or hazardous materials or other chemicals or substances
   regulated by any Environmental Laws ("Hazardous Substances") which any one
   of them has generated, transported or disposed of has been found at any
   site at which a federal, state or local agency or other third party has
   conducted or has ordered that any Borrower conduct a remedial
   investigation, removal or other response action pursuant to any
   Environmental Law; or (iii) that it is or shall be a named party to any
   claim, action, cause of action, complaint, legal or administrative
   proceeding arising out of any third party's incurrence of costs, expenses,
   losses or damages of any kind whatsoever in connection with the release of
   Hazardous Substances.

        (c)  (i) No portion of the Real Property has been used for the
   handling, processing, storage or disposal of Hazardous Substances except
   in material compliance with applicable Environmental Laws; and no
   underground tank or other underground storage receptacle for Hazardous
   Substances is located on such properties; (ii) in the course of any
   activities conducted by the Borrowers, or operators of the Real Property,
   no Hazardous Substances have been generated or are being used on such
   properties except in material compliance with applicable Environmental
   Laws; (iii) there have been no unpermitted Releases or threatened Releases
   of Hazardous Substances on, upon, into or from the Real Property, which
   Releases would have a material adverse effect on the value of such
   properties; (iv) to the best of the Borrowers' knowledge, there have been
   no Releases on, upon, from or into any real property in the vicinity of
   the Real Property which, through soil or groundwater contamination, may
   have come to be located on, and which would have a material adverse effect
   on the value of, such properties; and (v) in addition, any Hazardous
   Substances that have been generated on the Real Property have been
   transported offsite only by carriers having an identification number
   issued by the EPA, treated or disposed of only by treatment or disposal
   facilities maintaining valid permits as required under applicable
   Environmental Laws, which transporters and facilities, to the best of the
   Borrowers' knowledge, have been and are operating in material compliance
   with such permits and applicable Environmental Laws.

        (d)  None of the Real Property is or shall be subject to any
   applicable environmental clean-up responsibility law or environmental
   restrictive transfer law or regulation, by virtue of the transactions set
   forth herein and contemplated hereby.

        Section 5.17.  Perfection of Security Interests.  The Collateral and
   the Agent's rights with respect to the Collateral are not subject to any
   setoff, claims, withholdings or other defenses.  The Borrowers are the
   owners of the Collateral free from any lien, security interest,
   encumbrance and any other claim or demand, other than liens in favor of
   the Agent for the benefit of the Banks to secure the Obligations.  The
   Stock Pledge Agreement is effective to create in favor of the Agent, for
   the benefit of the Banks, a legal, valid and enforceable first priority
   security interest in the Collateral.  The certificates for the shares of
   such Collateral have been delivered to the Agent.

        Section 5.18.  Certain Transactions.    Except as set forth on
   Schedule 5.18 and except for arm's length transactions pursuant to which
   the Borrowers make payments in the ordinary course of business upon terms
   no less favorable than the Borrowers could obtain from third parties, none
   of the officers, directors, or employees of the Borrowers is presently a
   party to any transaction with the Borrowers (other than for services as
   employees, officers and directors), including any contract, agreement or
   other arrangement providing for the furnishing of services to or by,
   providing for rental of real or personal property to or from, or otherwise
   requiring payments to or from any officer, director or such employee or,
   to the knowledge of the Borrowers, any corporation, partnership, trust or
   other entity in which any officer, director, or any such employee has a

   of the Parent) to subscribe for or purchase from the Parent, or any
   warrants or other agreements providing for or requiring the issuance by
   the Parent of, any capital stock or any securities convertible into or

        Section 5.21.  True Copies of Charter and Other Documents.  The
   Borrowers have furnished the Agent copies, in each case true and complete
   as of the Closing Date, of (a) all charter and other incorporation

   with any amendments thereto).

        Section 5.22.  Disclosure.  No representation or warranty made by the
   Borrowers in this Agreement or in any agreement, instrument, document,
   certificate, statement or letter furnished to the Banks or the Agent by or
   on behalf of or at the request of the Borrowers in connection with any of
   the transactions contemplated by the Loan Documents contains any untrue
   statement of a material fact or omits to state a material fact necessary
   in order to make the statements contained therein not misleading in light
   of the circumstances in which they are made.

        Section 6.  AFFIRMATIVE COVENANTS OF THE BORROWERS.   The Borrowers
   jointly and severally covenant and agree that, so long as any Loan or Note
   is outstanding or the Banks have any obligation to make Loans or the Agent
   has any obligation to issue, extend, or renew any Letters of Credit
   hereunder:

        Section 6.1.  Punctual Payment.  The Borrowers will duly and
   punctually pay or cause to be paid the principal and interest of the
   Loans, all Reimbursement Obligations, fees and other amounts provided for
   in this Agreement and the other Loan Documents, all in accordance with the
   terms of this Agreement and such other Loan Documents.

        Section 6.2.  Maintenance of Office.  The Borrowers will maintain
   their chief executive offices at 10150 West National Avenue, Suite 350,
   West Allis, Wisconsin 53227, or at such other place in the United States
   of America as the Borrowers shall designate upon 30 days' prior written
   notice to the Agent.

        Section 6.3.  Records and Accounts.  Each of the Borrowers will keep

   all other contingencies, and all other proper reserves.

        Section 6.4.  Financial Statements, Certificates and Information. 
   The Borrowers will deliver to the Banks:

        (a)  as soon as practicable, but, in any event not later than 90 days
   after the end of each fiscal year of the Borrowers, the consolidated and
   consolidating balance sheets of Borrowers as at the end of such year,
   statements of cash flows, and the related consolidated and consolidating
   statements of operations, each setting forth in comparative form the
   figures for the previous fiscal year, all such consolidated and
   consolidating financial statements to be in reasonable detail, prepared in
   accordance with GAAP and, with respect to the consolidated financial
   statements, certified by the Accountants.  In addition, simultaneously
   therewith, the Borrowers shall use their best efforts to provide the Banks
   with a written statement from such Accountants to the effect that the
   Borrowers are in compliance with the covenants set forth in Section 8
   hereof, and that, in making the examination necessary to said
   certification, nothing has come to the attention of such Accountants that
   would indicate that any Default or Event of Default exists, or, if such
   Accountants shall have obtained knowledge of any then existing Default or
   Event of Default they shall disclose in such statement any such Default or
   Event of Default; provided, that such Accountants shall not be liable to
   the Banks for failure to obtain knowledge of any Default or Event of

   Default;

        (b)  as soon as practicable, but in any event not later than 45 days
   after the end of each fiscal quarter of the Borrowers, copies of the
   consolidated and consolidating balance sheets and statement of operations
   of the Borrowers as at the end of such quarter, subject to year end
   adjustments, and the related statement of cash flows, all in reasonable
   detail and prepared in accordance with GAAP, with a certification by the
   principal financial or accounting officer of the Borrowers (the "CFO")
   that the consolidated financial statements are prepared in accordance with
   GAAP and fairly present the consolidated financial condition of the
   Borrowers as at the close of business on the date thereof and the results
   of operations for the period then ended;

        (c)  simultaneously with the delivery of the financial statements
   referred to in (a) and (b) above, a statement in the form of Exhibit C
   hereto (the "Compliance Certificate") certified by the CFO that the
   Borrowers are in compliance with the covenants contained in Section
   Section 6, 7 and 8 hereof as of the end of the applicable period setting
   forth in reasonable detail computations evidencing such compliance,
   provided that if the Borrowers shall at the time of issuance of such
   certificate or at any other time obtain knowledge of any Default or Event
   of Default, the Borrowers shall include in such certificate or otherwise
   deliver forthwith to the Banks a certificate specifying the nature and
   period of existence thereof and what action the Borrowers propose to take
   with respect thereto and a certificate of the Borrowers' Chief Operating
   Officer in the form attached hereto as Exhibit D with respect to
   environmental matters;

        (d)  contemporaneously with or promptly following the delivery
   thereof to the board of directors of the Parent, copies of the financial
   statements, financial projections, and variance reports concerning the
   Parent in substantially the same form in which such information is
   supplied to the board of directors of the Parent;

        (e)  contemporaneously with, or promptly following, the filing or
   mailing thereof, copies of all material of a financial nature filed with
   the Securities and Exchange Commission or sent to the stockholders of the
   Parent or any of the Borrowers; and

        (f)  from time to time, such other financial data and other
   information (including accountants' management letters) as the Banks may
   reasonably request.

        The Borrowers hereby authorize the Banks to disclose any information
   obtained pursuant to this Agreement to all appropriate governmental
   regulatory authorities where required by law; provided, however, that the
   Banks shall, to the extent practicable and allowable under law, notify the
   Borrowers within a reasonable period prior to the time any such disclosure
   is made; and provided further, that this authorization shall not be deemed
   to be a waiver of any rights to object to the disclosure by the Banks of
   any such information which any Borrower has or may have under the federal
   Right to Financial Privacy Act of 1978, as in effect from time to time.

        Section 6.5.  Corporate Existence and Conduct of Business.Except
   where the failure of a Borrower to remain so qualified would not
   materially adversely impair the financial condition of the Borrowers on a
   consolidated basis, each Borrower will do or cause to be done all things
   necessary to preserve and keep in full force and effect its corporate
   existence, corporate rights and franchises; effect and maintain its
   foreign qualifications, licensing, domestication or authorization except
   as terminated by its Board of Directors in the exercise of its reasonable
   judgment; use its best efforts to comply with all applicable laws; and
   shall not become obligated under any contract or binding arrangement
   which, at the time it was entered into would materially adversely impair
   the financial condition of the Borrowers on a consolidated basis.  Each
   Borrower will continue to engage primarily in the businesses now conducted
   by it and in related businesses.

        Section 6.6.  Maintenance of Properties.  The Borrowers will cause
   all material properties used or useful in the conduct of their businesses
   to be maintained and kept in good condition, repair and working order and
   supplied with all necessary equipment and will cause to be made all
   necessary repairs, renewals, replacements, betterments and improvements
   thereof, all as in the judgment of the Borrowers may be necessary so that
   the businesses carried on in connection therewith may be properly and
   advantageously conducted at all times; provided, however, that nothing in
   this section shall prevent any Borrower from discontinuing the operation
   and maintenance of any of its properties if such discontinuance is, in the
   judgment of such Borrower, desirable in the conduct of its or their
   business and which does not in the aggregate materially adversely affect
   the businesses of the Borrowers on a consolidated basis.

        Section 6.7.  Insurance.  The Borrowers will maintain with
   financially sound and reputable insurance companies, funds or
   underwriters' insurance of the kinds, covering the risks (other than risks
   arising out of or in any way connected with personal liability of any
   officers and directors thereof) and in the relative proportionate amounts
   usually carried by reasonable and prudent companies conducting businesses
   similar to that of the Borrowers, but in no event less than the amounts
   and coverages set forth in Schedule 6.7 hereto.  In addition, the
   Borrowers will furnish from time to time, upon the Agent's request, a
   summary of the insurance coverage of each of the Borrowers, which summary
   shall be in form and substance satisfactory to the Agent and, if requested
   by the Agent, will furnish to the Agent copies of the applicable policies.

        Section 6.8.  Taxes.  The Borrowers will each duly pay and discharge,
   or cause to be paid and discharged, before the same shall become overdue,
   all taxes, assessments and other governmental charges (other than taxes,
   assessments and other governmental charges imposed by foreign
   jurisdictions which in the aggregate are not material to the business or
   assets of any Borrower on an individual basis or of the Borrowers on a
   consolidated basis) imposed upon it and its real properties, sales and
   activities, or any part thereof, or upon the income or profits therefrom,
   as well as all claims for labor, materials, or supplies, which if unpaid
   might by law become a lien or charge upon any of its property; provided,
   however, that any such tax, assessment, charge, levy or claim need not be
   paid if the validity or amount thereof shall currently be contested in
   good faith by appropriate proceedings and if such Borrower shall have set
   aside on its books adequate reserves with respect thereto; and provided,
   further, that such Borrower will pay all such taxes, assessments, charges,
   levies or claims forthwith upon the commencement of proceedings to
   foreclose any lien which may have attached as security therefor.

        Section 6.9.  Inspection of Properties, Books, and Contracts.  The
   Borrowers shall permit the Banks, the Agent or any of their designated
   representatives, upon reasonable notice, to visit and inspect any of the
   properties of the Borrowers, to examine the books of account of the
   Borrowers (including the making of periodic accounts receivable reviews),
   or contracts (and to make copies thereof and extracts therefrom), and to
   discuss the affairs, finances and accounts of the Borrowers with, and to
   be advised as to the same by, their officers, all at such times and
   intervals as the Banks may reasonably request.

        Section 6.10.  Compliance with Laws, Contracts, Licenses and Permits;
   Maintenance of Material Licenses and Permits.  Each Borrower will (i)
   comply with the provisions of its charter documents and by-laws and all
   agreements and instruments by which it or any of its properties may be
   bound; and (ii) comply with all applicable laws and regulations (including
   Environmental Laws), decrees, orders, judgments, licenses and permits,
   including, without limitation, all environmental permits hereto
   ("Applicable Laws"), except where noncompliance with such Applicable Laws
   would not have a material adverse effect in the aggregate on the
   consolidated financial condition, properties or businesses of the
   Borrowers.  If at any time while the Notes, or any Loan or Letter of
   Credit is outstanding or any Bank or the Agent has any obligation to make
   Loans or issue Letters of Credit hereunder, any authorization, consent,
   approval, permit or license from any officer, agency or instrumentality of
   any government shall become necessary or required in order that any
   Borrower may fulfill any of its obligations hereunder, such Borrower will
   immediately take or cause to be taken all reasonable steps within the
   power of such Borrower to obtain such authorization, consent, approval,
   permit or license and furnish the Banks with evidence thereof.

        Section 6.11.  ENVIRONMENTAL INDEMNIFICATION.  THE BORROWERS COVENANT
   AND AGREE THAT THEY WILL INDEMNIFY AND HOLD THE BANKS HARMLESS FROM AND
   AGAINST ANY AND ALL CLAIMS, EXPENSE, DAMAGE, LOSS OR LIABILITY INCURRED BY
   THE BANKS (INCLUDING ALL COSTS OF LEGAL REPRESENTATION INCURRED BY THE
   BANKS) RELATING TO (A) ANY RELEASE OR THREATENED RELEASE OF HAZARDOUS
   SUBSTANCES ON THE REAL PROPERTY; (B) ANY VIOLATION OF ANY ENVIRONMENTAL
   LAWS WITH RESPECT TO CONDITIONS AT THE REAL PROPERTY OR THE OPERATIONS
   CONDUCTED THEREON; OR (C) THE INVESTIGATION OR REMEDIATION OF OFFSITE
   LOCATIONS AT WHICH THE BORROWERS OR THEIR PREDECESSORS ARE ALLEGED TO HAVE
   DIRECTLY OR INDIRECTLY DISPOSED OF HAZARDOUS SUBSTANCES.  IT IS EXPRESSLY
   ACKNOWLEDGED BY THE BORROWERS THAT THIS COVENANT OF INDEMNIFICATION SHALL
   INCLUDE CLAIMS, EXPENSE, DAMAGE, LOSS OR LIABILITY INCURRED BY THE BANKS
   BASED UPON THE BANKS' NEGLIGENCE, AND THIS COVENANT SHALL SURVIVE ANY
   FORECLOSURE OR ANY MODIFICATION, RELEASE OR DISCHARGE OF THE STOCK PLEDGE
   AGREEMENT OR THE PAYMENT OF THE LOANS AND SHALL INURE TO THE BENEFIT OF
   THE BANKS, THEIR SUCCESSORS AND ASSIGNS.

        Section 6.12.  Further Assurances.  The Borrowers will cooperate with
   the Banks and execute such further instruments and documents as the Banks
   shall reasonably request to carry out to the Banks' satisfaction the
   transactions contemplated by this Agreement.

        Section 6.13.  Notice of Potential Claims or Litigation.  The
   Borrowers shall deliver to the Banks, within 30 days of receipt thereof,
   written notice of the initiation of any action, claim, complaint, or any
   other notice of dispute or potential litigation (including without
   limitation any alleged violation of any Environmental Law), wherein the
   potential liability is in excess of $500,000, together with a copy of each
   such notice received by any Borrower.

        Section 6.14.  Notice of Certain Events Concerning Insurance and
   Environmental Claims.

             (a)  The Borrowers will provide the Banks with written notice as
   to any cancellation or material change in any insurance of any of the
   Borrowers within ten (10) Business Days after such Borrower's receipt of
   any notice (whether formal or informal) of such cancellation or change by
   any of its insurers.

             (b)  The Borrowers will promptly notify the Banks in writing of
   any of the following events:

                  (i)  upon any Borrower obtaining knowledge of any violation
   of any Environmental Law regarding the Real Property or any Borrower's
   operations, which violation could have a material adverse effect on the
   Real Property or on any Borrower's operations; (ii) upon any Borrower
   obtaining knowledge of any potential or known Release or threat of Release
   of any Hazardous Substance at, from, or into the Real Property which it
   reports in writing or is reportable by it in writing to any governmental
   authority and which is material in amount or nature or which could
   materially affect the value of the Real Property; (iii) upon any
   Borrower's receipt of any notice of violation of any Environmental Laws or
   of any Release or threatened Release of Hazardous Substances, including a
   notice or claim of liability or potential responsibility from any third
   party (including without limitation any federal, state or local
   governmental officials) and including notice of any formal inquiry,
   proceeding, demand, investigation or other action with regard to (A) any
   Borrower's, or any Person's operation of the Real Property, (B)
   contamination on, from or into the Real Property, or (C) investigation or
   remediation of offsite locations at which any Borrower, or any of their
   predecessors is alleged to have directly or indirectly Disposed of
   Hazardous Substances; or (iv) upon any Borrower obtaining knowledge that
   any expense or loss has been incurred by such governmental authority in
   connection with the assessment, containment, removal or remediation of any
   Hazardous Substances with respect to which any Borrower may be liable or
   for which a lien may be imposed on the Real Property.

        Section 6.15.  Response Actions.  The Borrowers covenant and agree
   that if any Release or Disposal of Hazardous Substances shall occur or
   shall have occurred on the Real Property, the Borrowers will cause the
   prompt containment and removal of such Hazardous Substances and
   remediation of the Real Property as necessary to comply with all
   Environmental Laws or to preserve the value of the Real Property.

        Section 6.16.  Environmental Assessments.  If the Banks in their good
   faith judgment, after discussion with the Borrowers, have reason to
   believe that the value of the Real Property may have declined since the
   Closing Date or that the environmental condition of the Real Property has
   deteriorated, after reasonable notice by the Banks, whether or not an
   Event of Default shall have occurred, the Banks may, from time to time,
   for the purpose of assessing and ensuring the value of the Real Property,
   obtain one or more environmental assessments or audits of the Real
   Property prepared by a hydrogeologist, an independent engineer or other
   qualified consultant or expert approved by the Banks to evaluate or
   confirm (i) whether any Hazardous Substances are present in the soil or
   water at the Real Property and (ii) whether the use and operation of the
   Real Property complies with all Environmental Laws.  Environmental
   assessments may include without limitation detailed visual inspections of
   the Real Property including, without limitation, any and all storage
   areas, storage tanks, drains, dry wells and leaching areas, and the taking
   of soil samples, surface water samples and ground water samples, as well
   as such other investigations or analyses as the Banks deem appropriate. 
   All such environmental assessments shall be at the sole cost and expense
   of the Borrowers.

        Section 6.17.  Notice of Default.  The Borrowers will promptly notify
   the Banks in writing of the occurrence of any Default or Event of Default. 
   If any Person shall give any notice or take any other action in respect of
   a claimed default (whether or not constituting an Event of Default) under
   this Agreement or any other note, evidence of Indebtedness, indenture or
   other obligation evidencing Indebtedness in excess of $250,000 as to which
   any Borrower is a party or obligor, whether as principal or surety, the
   Borrowers shall forthwith give written notice thereof to the Banks,
   describing the notice of action and the nature of the claimed default.

        Section 6.18.  Closure and Post Closure Liabilities.   The Borrowers
   shall at all times adequately accrue, in accordance with GAAP and as
   required by applicable Environmental Laws, all closure and post closure
   liabilities with respect to the operations of the Borrowers.

        Section 7.   CERTAIN NEGATIVE COVENANTS OF THE BORROWERS.  The
   Borrowers agree that, so long as any Loan or any Note is outstanding or
   the Banks have any obligation to make Loans or the Agent has any
   obligation to issue, extend or renew any Letters of Credit hereunder:

   agreement to purchase any obligations, stock, assets, goods or services,

        Section 7.5.  Sale and Leaseback.  None of the Borrowers shall enter
   into any arrangement, directly or indirectly, whereby any Borrower shall
   sell or transfer any property owned by it in order then or thereafter to

   acquire shares of any class of capital stock of the Borrowers in an

   whether or not such deficiency is or may be waived; or

        (c)  fail to contribute to any Guaranteed Pension Plan to an extent
   which, or terminate any Guaranteed Pension Plan in a manner which, could

   Borrower pursuant to Section 302(f) or Section 4068 of ERISA; or

        (d)  permit or take any action which would result in the aggregate

   assets of any such Plan with assets in excess of benefit liabilities.

   connection with this Agreement shall be true as of the date as of which
   they were made and shall also be true at and as of the time of any
   Drawdown Date with the same effect as if made at and as of that time
   (except to the extent of changes resulting from transactions contemplated
   or permitted by this Agreement and changes occurring in the ordinary
   course of business which singly or in the aggregate are not materially

        Section 10.2.  Performance; No Event of Default.  The Borrowers shall
   have performed and complied with all terms and conditions herein required
   to be performed or complied with by them prior to or at the time of any
   Loan, and at the time of any Loan, there shall exist no Event of Default
   or condition which would result in an Event of Default upon consummation
   of such Loan (including without limitation any amounts to be drawn under a
   Letter of Credit).  Each request by the Borrowers for a Loan (including
   without limitation each request for issuance of a Letter of Credit)
   subsequent to the first Loan shall constitute certification by the
   Borrowers that the conditions specified in Section Section 10.1 and 10.2
   will be duly satisfied on the date of such Loan or Letter of Credit
   issuance.

        Section 10.3.  No Legal Impediment.  No change shall have occurred in
   any law or regulations thereunder or interpretations thereof which in the
   reasonable opinion of the Banks would make it illegal for the Banks to
   make Loans hereunder.

        Section 10.4.  Governmental Regulation.  The Banks shall have
   received such statements in substance and form reasonably satisfactory to
   the Banks as they shall require for the purpose of compliance with any

   attached hereto as Exhibit B, and the Banks shall have received all
   information and such counterpart originals or certified or other copies of
   such documents as the Banks may reasonably request.

   hereafter acquired, pursuant to the terms of the Stock Pledge Agreement.

        Section 12.  EVENTS OF DEFAULT; ACCELERATION; TERMINATION OF
                     COMMITMENT.  

        Section 12.1.  Events of Default and Acceleration.  If any of the
   following events ("Events of Default" or, if the giving of notice or the
   lapse of time or both is required, then, prior to such notice and/or lapse
   of time, "Defaults") shall occur:

        (a)  if the Borrowers shall fail to pay any principal of the Loans
   when the same shall become due and payable, whether at the Maturity Date
   or any accelerated date of maturity or at any other date fixed for
   payment;

        (b)  if the Borrowers shall fail to pay any interest or fees or other
   amounts owing hereunder within five (5) Business Days after the same shall
   become due and payable whether at the Maturity Date or any accelerated
   date of maturity or at any other date fixed for payment;

        (c)  if the Borrowers shall fail to comply with the covenants
   contained in Section Section 6, 7 or 8 hereof;

   than those specified in subsections (a), (b), and (c) above) within 30
   days after written notice of such failure has been given to the Borrowers
   by the Banks;

        (e)  if any representation or warranty contained in this Agreement or
   in any document or instrument delivered pursuant to or in connection with
   this Agreement shall prove to have been false in any material respect upon
   the date when made or repeated;

        (f)  if any Borrower shall fail to pay at maturity, or within any
   applicable period of grace, any and all obligations for borrowed money
   (other than the Obligations) or any guaranty with respect thereto in an
   aggregate amount greater than $250,000, or fail to observe or perform any
   material term, covenant or agreement contained in any agreement by which
   it is bound, evidencing or securing borrowed money in an aggregate amount
   greater than $250,000 for such period of time as would, or would have
   permitted (assuming the giving of appropriate notice if required) the
   holder or holders thereof or of any obligations issued thereunder to
   accelerate the maturity thereof; or

        (g)  if any Borrower makes an assignment for the benefit of
   creditors, or admits in writing its inability to pay or generally fails to
   pay its debts as they mature or become due, or petitions or applies for
   the appointment of a trustee or other custodian, liquidator or receiver of
   any Borrower or of any substantial part of the assets of any Borrower or
   commences any case or other proceeding relating to any Borrower under any
   bankruptcy, reorganization, arrangement, insolvency, readjustment of debt,
   dissolution or liquidation or similar law of any jurisdiction, now or
   hereafter in effect, or takes any action to authorize or in furtherance of
   any of the foregoing, or if any such petition or application is filed or
   any such case or other proceeding is commenced against any Borrower and or
   any Borrower indicates its approval thereof, consent thereto or
   acquiescence therein;

        (h)  a decree or order is entered appointing any such trustee,
   custodian, liquidator or receiver or adjudicating any Borrower bankrupt or
   insolvent, or approving a petition in any such case or other proceeding,
   or a decree or order for relief is entered in respect of any Borrower in
   an involuntary case under federal bankruptcy laws as now or hereafter
   constituted, and such decree or order remains in effect for more than
   sixty (60) days, whether or not consecutive;

        (i)  if there shall remain in force, undischarged, unsatisfied and
   unstayed, for more than thirty (30) days, whether or not consecutive, any
   final judgment against any Borrower which, with other outstanding final
   judgments against any Borrower, exceeds in the aggregate $500,000 after
   taking into account any undisputed insurance coverage;

        (j)  with respect to any Guaranteed Pension Plan, an ERISA Reportable
   Event shall have occurred and the Banks shall have determined in their
   reasonable discretion that such event reasonably could be expected to
   result in liability of any Borrower to the PBGC or the Plan in an
   aggregate amount exceeding $500,000 and such event in the circumstances
   occurring reasonably could constitute grounds for the termination of such
   Plan by the PBGC or for the appointment by the appropriate United States
   District Court of a trustee to administer such Plan; or a trustee shall
   have been appointed by the United States District Court to administer such
   Plan; or the PBGC shall have instituted proceedings to terminate such
   Plan;

        (k)  if any of the Loan Documents shall be cancelled, terminated,
   revoked or rescinded otherwise than in accordance with the terms thereof
   or with the express prior written agreement, consent or approval of the
   Banks, or any action at law, suit or in equity or other legal proceeding
   to cancel, revoke or rescind any of the Loan Documents shall be commenced
   by or on behalf of the Borrowers or any of their respective stockholders,
   or any court or any other governmental or regulatory authority or agency
   of competent jurisdiction shall make a determination that, or issue a
   judgment, order, decree or ruling to the effect that, any one or more of
   the Loan Documents is illegal, invalid or unenforceable in accordance with
   the terms thereof; or

        (l)  any person or group of persons (within the meaning of Section 13
   or 14 of the Securities Exchange Act of 1934, as amended) shall have
   acquired beneficial ownership (within the meaning of Rule 13d-3
   promulgated by the Securities and Exchange Commission under said Act) of
   20% or more of the outstanding shares of common stock of the Borrower; or,
   during any period of twelve consecutive calendar months, individuals who
   were directors of the Borrower on the first day of such period shall cease
   to constitute a majority of the board of directors of the Borrower; then,
   and in any such event, so long as the same may be continuing, upon the
   request of the Banks, the Agent shall, by notice in writing to the
   Borrowers, declare all amounts owing with respect to this Agreement, the
   Notes and the other Loan Documents and all Reimbursement Obligations to
   be, and they shall thereupon forthwith become, immediately due and payable
   without presentment, demand, protest or other notice of any kind, all of
   which are hereby expressly waived by the Borrowers; provided that in the
   event of any Event of Default specified in Section 12(g) or 12(h), all
   such amounts shall become immediately due and payable automatically and
   without any requirement of notice from the Agent or any Bank.  Upon demand
   by the Banks after the occurrence of any Event of Default, the Borrowers
   shall immediately provide to the Agent cash in an amount equal to the
   aggregate Maximum Drawing Amount of all Letters of Credit outstanding, to
   be held by the Agent as collateral security for the Obligations.

        Section 12.2.  Termination of Commitments.  If any Event of Default
   shall occur, any unused portion of the Total Commitment hereunder shall
   forthwith terminate and the Banks shall be relieved of all obligations to
   make Loans to or issue Letters of Credit for the account of any of the
   Borrowers; or if on any Drawdown Date the conditions precedent to the
   making of the Loans to be made on such Drawdown Date or the issuance of
   any Letters of Credit to be issued on such date are not satisfied (except
   as a consequence of a default on the part of the Banks), the Banks may by
   notice to the Borrowers, terminate the unused portion of the Total
   Commitment hereunder, and upon such Notice being given, such unused
   portion of the Total Commitment hereunder shall terminate immediately and
   the Banks shall be relieved of all further obligations to make Loans to or
   issue Letters of Credit for the account of the Borrowers hereunder.  No
   termination of any portion of the Total Commitment hereunder shall relieve
   the Borrowers of any of their existing Obligations to the Banks hereunder
   or elsewhere.

        Section 12.3.  Remedies.  Subject to Section 14.8, in case any one or
   more of the Events of Default shall have occurred and be continuing, and
   whether or not the Banks shall have accelerated the maturity of the Loans
   pursuant to Section 12.1, each Bank, if owed any amount with respect to
   the Loans or the Reimbursement Obligations, may proceed to protect and
   enforce its rights by suit in equity, action at law or other appropriate
   proceeding, whether for the specific performance of any covenant or
   agreement contained in this Agreement and the other Loan Documents or any
   instrument pursuant to which the Obligations or the Guaranteed Obligations
   to such Bank are evidenced, including, without limitation, as permitted by
   applicable law the obtaining of the ex parte appointment of a receiver,
   and, if such amount shall have become due, by declaration or otherwise,
   proceed to enforce the payment thereof or any legal or equitable right of
   such Bank.  No remedy herein conferred upon any Bank or the Agent or the
   holder of any Note or purchaser of any Letter of Credit Participation is
   intended to be exclusive of any other remedy and each and every remedy
   shall be cumulative and shall be in addition to every other remedy given
   hereunder or now or hereafter existing at law or in equity or by statute
   or any other provision of law.

        Section 13.  SETOFF.  Regardless of the adequacy of any collateral,
   during the continuance of an Event of Default, any deposits or other sums
   credited by or due from any Bank to the Borrowers and any securities or
   other property of the Borrowers in the possession of such Bank may be
   applied to or set off against the payment of the Obligations and any and
   all other liabilities, direct or indirect, absolute or contingent, due or
   to become due, now existing or hereafter arising, of the Borrowers to the
   Banks.  The Banks agree among themselves that, if a Bank shall obtain
   payment on any loan outstanding under this Agreement through the exercise
   of a right of offset, banker's lien or counterclaim, or from any other
   source (other than by way of a pro rata payment under this Agreement or a
   required payment under a Note), it shall promptly make such adjustments
   with the other Banks as shall be equitable to the end that all the Banks
   shall share the benefits of such payments pro rata in accordance with the
   aggregate unpaid amount of the Notes held by each Bank immediately prior
   to the payment obtained by such Bank as aforesaid.  The Banks further
   agree among themselves that if any payment to a Bank obtained by such Bank
   through the exercise of a right of offset, banker's lien or counterclaim,
   or from any other source (other than by way of a pro rata payment) as
   aforesaid shall be rescinded or must otherwise be restored, the Banks who
   shall have shared the benefit of such payment shall return their share of
   that benefit to the Bank whose payment shall have been rescinded or
   otherwise restored.

        Section 14.  THE AGENT.  

        Section 14.1.  Appointment of Agent, Powers and Immunities.  Each
   Bank hereby irrevocably appoints and authorizes the Agent to act as its
   agent hereunder and under the other Loan Documents, provided, however, the
   Agent is hereby authorized to serve only as an administrative and
   collateral agent for the Banks and to exercise such powers as are
   reasonably incidental thereto and as are set forth in this Agreement and
   the other Loan Documents.  The Agent hereby acknowledges that it does not
   have the authority to negotiate any agreement which would bind the Banks
   or agree to any amendment, waiver or modification of any of the Loan
   Documents or bind the Banks except as set forth in this Agreement or the
   Loan Documents.  Except as provided in this Section 14 and in the other
   Loan Documents, the Agent shall take action or refrain from acting only
   upon instructions of the Banks and no action taken or failure to act
   without the consent of the Banks shall be binding on any Bank which has
   not consented.  Each Bank irrevocably authorizes the Agent to execute the
   Stock Pledge Agreement and all other instruments relating thereto and to
   take such action on behalf of each of the Banks and to exercise all such
   powers as are expressly delegated to the Agent under the Loan Documents
   and all related documents, together with such other powers as are
   reasonably incidental thereto.  It is agreed that the duties, rights,
   privileges and immunities of the Agent, in its capacity as issuer of
   Letters of Credit hereunder, shall be identical to its duties, rights,
   privileges and immunities as a Bank as provided in this Section 14.  The
   Agent shall not have any duties or responsibilities or any fiduciary
   relationship with any Bank except those expressly set forth in this
   Agreement.  Neither the Agent nor any of its affiliates shall be
   responsible to the Banks for any recitals, statements, representations or
   warranties made by the Borrowers or any other Person whether contained
   herein or otherwise or for the value, validity, effectiveness,
   genuineness, enforceability or sufficiency of this Agreement, the other
   Loan Documents or any other document referred to or provided for herein or
   therein or for any failure by the Borrowers or any other Person to perform
   its obligations hereunder or thereunder or in respect of the Notes.  The
   Agent may employ agents and attorneys-in-fact and shall not be responsible
   for the negligence or misconduct of any such agents or attorneys-in-fact
   selected by it with reasonable care.  The Agent shall exercise the same
   care in administering the Loan as its exercises with respect to similar
   transactions entered into solely for its own account; however, neither the
   Agent nor any of its directors, officers, employees or agents shall be
   responsible for any action taken or omitted to be taken in good faith by
   it or them hereunder or in connection herewith, except for its or their
   own gross negligence or willful misconduct.  The Bank in its separate
   capacity as a Bank shall have the same rights and powers hereunder as any
   other Bank.

        Section 14.2.  Actions By Agent.  The Agent shall be fully justified
   in failing or refusing to take any action under this Agreement as it
   reasonably deems appropriate unless it shall first have received such
   advice or concurrence of the Banks and shall be indemnified to its
   reasonable satisfaction by the Banks against any and all liability and
   expense which may be incurred by it by reason of taking or continuing to
   take any such action.  The Agent shall in all cases be fully protected in
   acting, or in refraining from acting, under this Agreement or any of the
   Loan Documents in accordance with a request of the Banks, and such request
   and any action taken or failure to act pursuant thereto shall be binding
   upon the Banks and all future holders of the Notes or any Letter of Credit
   Participation.

        Section 14.3.  INDEMNIFICATION.  WITHOUT LIMITING THE OBLIGATIONS OF
   THE BORROWERS HEREUNDER OR UNDER ANY OTHER LOAN DOCUMENT, THE BANKS AGREE
   TO INDEMNIFY THE AGENT, RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE
   COMMITMENT PERCENTAGES, FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
   DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
   DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER (OTHER THAN LOSSES WITH
   RESPECT TO THE AGENT'S PRO RATA SHARE OF THE OBLIGATIONS) WHICH MAY AT ANY
   TIME BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT IN ANY WAY
   RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
   ANY DOCUMENTS CONTEMPLATED BY OR REFERRED TO  HEREIN OR THEREIN OR THE
   TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY OR THE ENFORCEMENT OF ANY OF
   THE TERMS HEREOF OR THEREOF OR OF ANY SUCH OTHER DOCUMENTS; PROVIDED, THAT
   NO BANK SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE
   FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT (OR ANY AGENT
   THEREOF), IT BEING THE INTENT OF THE PARTIES HERETO THAT ALL SUCH
   INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR THEIR ORDINARY SOLE OR
   CONTRIBUTORY NEGLIGENCE.

        Section 14.4.  Reimbursement.  Without limiting the provisions of
   Section 14.3, the Banks and the Agent hereby agree that the Agent shall
   not be obliged to make available to any Person any sum which the Agent is
   expecting to receive for the account of that Person until the Agent has
   determined that it has received that sum.  The Agent may, however,
   disburse funds prior to determining that the sums which the Agent expects
   to receive have been finally and unconditionally paid to the Agent, if the
   Agent wishes to do so.  If and to the extent that the Agent does disburse
   funds and it later becomes apparent that the Agent did not then receive a
   payment in an amount equal to the sum paid out, then any Person to whom
   the Agent made the funds available shall, on demand from the Agent, refund
   to the Agent the sum paid to that Person.  If, in the opinion of the
   Agent, the distribution of any amount received by it in such capacity
   hereunder or under the Loan Documents might involve it in liability, it
   may refrain from making distribution until its right to make distribution
   shall have been adjudicated by a court of competent jurisdiction.  If a
   court of competent jurisdiction shall adjudge that any amount received and
   distributed by the Agent is to be repaid, each Person to whom any such
   distribution shall have been made shall either repay to the Agent its
   proportionate share of the amount so adjudged to be repaid or shall pay
   over the same in such manner and to such Persons as shall be determined by
   such court.

        Section 14.5.  Documents.  The Agent will forward to each Bank,
   promptly after the Agent's receipt thereof, a copy of each notice or other
   document furnished to the Agent for such Bank hereunder; provided,
   however, that, notwithstanding the foregoing, the Agent may furnish to the
   Banks a monthly summary with respect to Letters of Credit issued hereunder
   in lieu of copies of the related Letter of Credit Applications.

        Section 14.6.  Non-Reliance on Agent and Other Banks.  Each Bank
   represents that it has, independently and without reliance on the Agent or
   any other Bank, and based on such documents and information as it has
   deemed appropriate, made its own appraisal of the financial condition and
   affairs of the Borrowers and decision to enter into this Agreement and the
   other Loan Documents and agrees that it will, independently and without
   reliance upon the Agent or any other Bank, and based on such documents and
   information as it shall deem appropriate at the time, continue to make its
   own appraisals and decisions in taking or not taking action under this
   Agreement or any other Loan Document.  The Agent shall not be required to
   keep informed as to the performance or observance by the Borrowers of this
   Agreement, the other Loan Documents or any other document referred to or
   provided for herein or therein or by any other Person of any other
   agreement or to make inquiry of, or to inspect the properties or books of,
   any Person.  Except for notices, reports and other documents and
   information expressly required to be furnished to the Banks by the Agent
   hereunder, the Agent shall not have any duty or responsibility to provide
   any Bank with any credit or other information concerning any person which
   may come into the possession of the Agent or any of its affiliates.  Each
   Bank shall have access to all documents relating to the Agent's
   performance of its duties hereunder at such Bank's request.  Unless any
   Bank shall promptly object to any action taken by the Agent hereunder
   (other than actions to which the provisions of Section 14.8 are applicable
   and other than actions which constitute gross negligence or willful
   misconduct by the Agent), such Bank shall conclusively be presumed to have
   approved the same.

        Section 14.7.  Resignation or Removal of Agent.  The Agent may resign
   at any time by giving 60 days' prior written notice thereof to the Banks
   and the Borrowers.  Upon any such resignation, the Banks shall have the
   right to appoint a successor Agent.  If no successor Agent shall have been
   so appointed by the Banks and shall have accepted such appointment within
   30 days after the retiring Agent's giving of notice of resignation, then
   the retiring Agent may, on behalf of the Banks, appoint a successor Agent,
   which shall be a financial institution having a combined capital and
   surplus in excess of $150,000,000.  Upon the acceptance of any appointment
   as Agent hereunder by a successor Agent, such successor Agent shall
   thereupon succeed to and become vested with all the rights, powers,
   privileges and duties of the retiring Agent, and the retiring Agent shall
   be discharged from its duties and obligations hereunder.  After any
   retiring Agent's resignation, the provisions of this Agreement shall
   continue in effect for its benefit in respect of any actions taken or
   omitted to be taken by it while it was acting as Agent.  Any new Agent
   appointed pursuant to this Section 14.7 shall immediately issue new
   Letters of Credit in place of Letters of Credit previously issued by the
   Agent.

        Section 14.8.  Action by the Banks, Consents, Amendments, Waivers,
   Etc.  Except as otherwise expressly provided in this Section 14.8, any
   action to be taken (including the giving of notice) may be taken or any
   consent or approval required or permitted by the Agreement or any other
   Loan Document to be given by the Banks may be given, and any term of this
   Agreement, any other Loan Document or any other instrument, document or
   agreement related to this Agreement or the other Loan Documents or
   mentioned therein may be amended and the performance or observance by the
   Borrowers or any other person of any of the terms thereof and any Default
   or Event of Default (as defined in any of the above-referenced documents
   or instruments) may be waived (either generally or in a particular
   instance and either retroactively or prospectively) only with the written
   consent of the Majority Banks; provided, however, that no such consent or
   amendment which affects the rights, duties or liabilities of the Agent (in
   its capacity as Agent) shall be effective without the written consent of
   the Agent.  Notwithstanding the foregoing, no amendment, waiver or consent
   shall do any of the following unless in writing and signed by ALL of the
   Banks: (a) increase the principal amount of the Total Commitment (or
   subject the Banks to any additional obligations) other than in accordance
   with Section 2.2 hereof, (b) reduce the principal of or interest on the
   Notes (including, without limitation, interest on overdue amounts) or any
   fees payable hereunder, (c) postpone any date fixed for any payment in
   respect of principal or interest (including, without limitation, interest
   on overdue amounts) on the Notes, or any fees payable hereunder; (d)
   change the definition of "Majority Banks" or number of Banks which shall
   be required for the Banks or any of them to take any action under the Loan
   Documents; (e) amend this Section 14.8; (f) change the Commitment
   Percentage of any Bank, except as permitted under Section 18 hereof; or
   (g) except as otherwise permitted hereunder, release any Collateral.

        Section 15.  EXPENSES.  Whether or not the transactions contemplated
   herein shall be consummated, the Borrowers hereby promise to reimburse the
   Agent for all reasonable out-of-pocket fees and disbursements (including
   all reasonable attorneys' fees and Consulting Engineers' fees), incurred
   or expended in connection with the preparation, filing or recording, or
   interpretation of this Agreement, the other Loan Documents, or any
   amendment, modification, approval, consent or waiver hereof or thereof, or
   with the enforcement of any Obligations or the satisfaction of any
   indebtedness of the Borrowers hereunder or thereunder, or in connection
   with any litigation, proceeding or dispute hereunder in any way related to
   the credit hereunder.  The Borrowers will pay any taxes (including any
   interest and penalties in respect thereof) other than the Banks' federal
   and state income taxes, payable on or with respect to the transactions
   contemplated by this Agreement (the Borrowers hereby agreeing to indemnify
   the Banks with respect thereto).

        Section 16.  INDEMNIFICATION.  THE BORROWERS AGREE TO INDEMNIFY AND
   HOLD HARMLESS THE AGENT AND THE BANKS, AS WELL AS THEIR SHAREHOLDERS,
   DIRECTORS, AGENTS, OFFICERS, SUBSIDIARIES AND AFFILIATES, FROM AND AGAINST
   ALL DAMAGES, LOSSES, SETTLEMENT PAYMENTS, OBLIGATIONS, LIABILITIES,
   CLAIMS, SUITS, PENALTIES, ASSESSMENTS, CITATIONS, DIRECTIVES, DEMANDS,
   JUDGMENTS, ACTIONS OR CAUSES OF ACTION, WHETHER STATUTORILY CREATED OR
   UNDER THE COMMON LAW, AND REASONABLE COSTS AND EXPENSES INCURRED,
   SUFFERED, SUSTAINED OR REQUIRED TO BE PAID BY AN INDEMNIFIED PARTY BY
   REASON OF OR RESULTING FROM THE TRANSACTIONS CONTEMPLATED HEREBY, EXCEPT
   ANY OF THE FOREGOING WHICH RESULT FROM THE GROSS NEGLIGENCE OR WILLFUL
   MISCONDUCT OF THE INDEMNIFIED PARTY.  IN ANY INVESTIGATION, PROCEEDING OR
   LITIGATION, OR THE PREPARATION THEREFOR, EACH BANK AND THE AGENT SHALL BE
   ENTITLED TO SELECT ITS OWN COUNSEL, AND, IN ADDITION TO THE FOREGOING
   INDEMNITY, THE BORROWERS AGREE TO PAY PROMPTLY THE REASONABLE FEES AND
   EXPENSES OF SUCH COUNSEL.  IN THE EVENT OF THE COMMENCEMENT OF ANY SUCH
   PROCEEDING OR LITIGATION, THE BORROWERS SHALL BE ENTITLED TO PARTICIPATE
   IN SUCH PROCEEDING OR LITIGATION WITH COUNSEL OF THEIR CHOICE AT THEIR
   EXPENSE, PROVIDED THAT SUCH COUNSEL SHALL BE REASONABLY SATISFACTORY TO
   THE BANKS AND THE AGENT.  THE COVENANTS OF THIS Section 16 SHALL SURVIVE
   PAYMENT OR SATISFACTION OF PAYMENT OF AMOUNTS OWING WITH RESPECT TO THE
   NOTES OR ANY OTHER LOAN DOCUMENT, IT BEING THE INTENT OF THE PARTIES
   HERETO THAT ALL SUCH INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR THEIR
   ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

        Section 17.  SURVIVAL OF COVENANTS, ETC.  Unless otherwise stated
   herein, all covenants, agreements, representations and warranties made
   herein, in the other Loan Documents or in any documents or other papers
   delivered by or on behalf of the Borrowers pursuant hereto shall be deemed
   to have been relied upon by the Banks and the Agent, notwithstanding any
   investigation heretofore or hereafter made by any of them, and shall
   survive the making by the Banks of the Loans and the issuance, extension
   or renewal of any Letters of Credit, as herein contemplated, and shall
   continue in full force and effect so long as any amount due under this
   Agreement, any Letter of Credit or the Notes remains outstanding and
   unpaid or any Bank has any obligation to make any Loans or issue any
   Letters of Credit hereunder.  All statements contained in any certificate
   or other paper delivered by or on behalf of the Borrowers pursuant hereto
   or in connection with the transactions contemplated hereby shall
   constitute representations and warranties by the Borrowers hereunder.

        Section 18.  ASSIGNMENT AND PARTICIPATION.  It is understood and
   agreed that each Bank shall have the right to assign or participate at any
   time all or a portion of its Commitment and interests in the risk relating
   to any Loans and outstanding Letters of Credit hereunder in an amount
   equal to or greater than $10,000,000 (which assignment shall be of an
   equal percentage of the Commitment, the Loans and outstanding Letters of
   Credit) to additional banks or other financial institutions so long as the
   Agent will be the Agent hereunder and with the prior written consent of
   the Agent and, unless a Default or an Event of Default shall have occurred
   and be continuing, the Borrowers, which approvals shall not be
   unreasonably withheld; and further, and that each bank or other financial
   institution which executes and delivers to the Banks and the Borrowers
   hereunder a counterpart joinder in form and substance satisfactory to the
   Banks and such bank or financial institution shall, on the date specified
   in such counterpart joinder, become a party to this Agreement and the
   other Loan Documents for all purposes of this Agreement, and its
   Commitment shall be as set forth in such counterpart joinder.  Upon the
   execution and delivery of such counterpart joinder and payment by the
   assigning bank of an assignment fee in the amount of $3,500 to the Agent,
   (a) the Borrowers shall issue to such bank or other financial institution
   a Note in the amount of such bank's or other financial institution's
   Commitment dated the Closing Date or such other date as may be specified
   by the Agent and otherwise completed in substantially the form of
   Exhibit A hereto; (b) the Agent shall distribute to the Borrowers, the
   Banks and such bank or financial institution a schedule reflecting such
   changes; (c) this Agreement shall be appropriately amended to reflect (i)
   the status of such bank or financial institution as a party hereto and
   (ii) the status and rights of the Banks and Agent hereunder; and (d) the
   Borrowers shall take such action as the Agent may reasonably request to
   perfect any security interests in favor of the Banks, including any bank
   or financial institution which becomes a party to this Agreement.  The
   documents evidencing any such participation may provide that, except with
   the consent of the bank or financial institution that is a party thereto,
   such Bank will not consent to (a) the reduction in or forgiveness of the
   stated principal of or rate of interest on or Commitment Fee with respect
   to the portion of any Loan subject to such participation or assignment,
   (b) the extension or postponement of any stated date fixed for payment of
   principal or interest or Commitment Fee with respect to the portion of any
   Loan subject to such participation or assignment, or (c) the waiver or
   reduction of any right to indemnification of such Bank hereunder. 
   Notwithstanding the foregoing, no syndication or participation shall
   operate to increase the Total Commitment hereunder or otherwise alter the
   substantive terms of this Agreement, except as contemplated under Section
   2.2(c).

        Section 19.  PARTIES IN INTEREST.  All the terms of this Agreement
   and the other Loan Documents shall be binding upon and inure to the
   benefit of and be enforceable by the respective successors and assigns of
   the parties hereto and thereto; provided that no Borrower shall assign or
   transfer its rights hereunder without the prior written consent of the
   Banks.

        Section 20.  NOTICES, ETC.  Except as otherwise expressly provided in
   this Agreement, all notices and other communications made or required to
   be given pursuant to this Agreement or the other Loan Documents shall be
   in writing and shall be delivered in hand, mailed by United States first-
   class mail, postage prepaid, or sent by telegraph, telex or telecopier and
   confirmed by letter, addressed as follows:

        (a)  if to the Borrowers, at 10150 West National Avenue, Suite 350,
   West Allis, Wisconsin 53227, Attention:  George K. Farr, Chief Financial
   Officer and Treasurer, telecopy number (414) 328-2899;

        (b)  if to the Agent or FNBB, at 100 Federal Street, Boston,
   Massachusetts 02110, Attention: Timothy M. Laurion, Vice President,
   telecopy number 617-434-2160; 

        or such other address for notice as shall have last been furnished in
   writing to the Person giving the notice.  

        Any such notice or demand shall be deemed to have been duly given or
   made and to have become effective (a) if delivered by hand to a
   responsible officer of the party to which it is directed, at the time of
   the receipt thereof by such officer, (b) if sent by registered or
   certified first-class mail, postage prepaid, five Business Days after the
   posting thereof, and (c) if sent by telex or cable, at the time of the
   dispatch thereof, if in normal business hours in the country of receipt,
   or otherwise at the opening of business on the following Business Day.

        Section 21.  MISCELLANEOUS.  The rights and remedies herein expressed
   are cumulative and not exclusive of any other rights which the Banks or
   Agent would otherwise have.  The captions in this Agreement are for
   convenience of reference only and shall not define or limit the provisions
   hereof.  This Agreement and any amendment hereof may be executed in
   several counterparts and by each party on a separate counterpart, each of
   which when so executed and delivered shall be an original, but all of
   which together shall constitute one instrument.  In proving this Agreement
   it shall not be necessary to produce or account for more than one such
   counterpart signed by the party against whom enforcement is sought.

        Section 22.  ENTIRE AGREEMENT, ETC.  The Loan Documents and any other
   documents executed in connection herewith or therewith express the entire
   understanding of the parties with respect to the transactions contemplated
   hereby.  Neither this Agreement nor any term hereof may be changed,
   waived, discharged or terminated, except as provided in Section 14.8.  No
   waiver shall extend to or affect any obligation not expressly waived or
   impair any right consequent thereon.  No course of dealing or omission on
   the part of the Agent or any Bank in exercising any right shall operate as
   a waiver thereof or otherwise be prejudicial thereto.  No notice to or
   demand upon the Borrowers shall entitle the Borrowers to other or further
   notice or demand in similar or other circumstances.

        Section 23.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWERS HEREBY
   WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM
   ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR
   ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR
   THEREUNDER OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.  EXCEPT AS
   PROHIBITED BY LAW, EACH BORROWER HEREBY WAIVES ANY RIGHT IT MAY HAVE TO
   CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THE PRECEDING SENTENCE
   ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES
   OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES.  THE BORROWERS (a) CERTIFY
   THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OR ANY BANK OF THE AGENT HAS
   REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH BANK OR THE AGENT WOULD
   NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND
   (b) ACKNOWLEDGE THAT THE AGENT AND THE BANKS HAVE BEEN INDUCED TO ENTER
   INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY
   BECAUSE OF, AMONG OTHER THINGS, THE BORROWERS' WAIVERS AND CERTIFICATIONS
   CONTAINED HEREIN.

        Section 24.  GOVERNING LAW.  THIS AGREEMENT AND EACH OF THE OTHER
   LOAN DOCUMENTS ARE CONTRACTS UNDER THE LAWS OF THE COMMONWEALTH OF
   MASSACHUSETTS AND SHALL FOR ALL PURPOSES BE CONSTRUED IN ACCORDANCE WITH
   AND GOVERNED BY THE LAWS OF SAID COMMONWEALTH (EXCLUDING THE LAWS
   APPLICABLE TO CONFLICTS OR CHOICE OF LAW).  THE BORROWERS CONSENT TO THE
   JURISDICTION OF ANY OF THE FEDERAL OR STATE COURTS LOCATED IN THE
   COMMONWEALTH OF MASSACHUSETTS IN CONNECTION WITH ANY SUIT TO ENFORCE THE
   RIGHTS OF ANY BANK OR THE AGENT UNDER THIS AGREEMENT OR ANY OF THE OTHER
   LOAN DOCUMENTS.

        Section 25.  SEVERABILITY.  The provisions of this Agreement are
   severable and if any one clause or provision hereof shall be held invalid
   or unenforceable in whole or in part in any jurisdiction, then such
   invalidity or unenforceability shall affect only such clause or provision,
   or part thereof, in such jurisdiction, and shall not in any manner affect
   such clause or provision in any other jurisdiction, or any other clause or
   provision of this Agreement in any jurisdiction.

        IN WITNESS WHEREOF, the undersigned have duly executed this Agreement
   under seal as of the date first set forth above.
