                           ARTICLE II

           COMMITMENTS, BORROWING PROCEDURES AND NOTES

     SECTION 2.1.  Commitments.  On the terms and subject to the conditions
of this Agreement (including Article V), each Lender severally agrees as
follows:

     SECTION 2.1.1.  Revolving Loan Commitment.  From time to time on any
Business Day occurring prior to the Commitment Termination Date, each Lender
will make Revolving Loans in Dollars and/or other Available Currencies
(relative to such Lender, its "Revolving Loans") to any Borrower equal to such
Lender's Percentage of the aggregate amount of the Borrowing of Revolving
Loans requested by such Borrower to be made on such day; provided, however
that the aggregate Dollar Amount of the principal amount of Loans by all the
Lenders in currencies other than Dollars shall not at any time exceed
$20,000,000 at any time outstanding.  On the terms and subject to the
conditions hereof, each Borrower may from time to time borrow, prepay and
reborrow Revolving Loans.

     SECTION 2.1.2.  Commitment to Issue Letters of Credit.  From time to
time on any Business Day, the Issuer will issue, and each Lender will
participate in, the Letters of Credit, in accordance with Article IV.

     SECTION 2.1.3.  Lenders Not Permitted or Required To Make Loans or
Issue or Participate in Letters of Credit Under Certain Circumstances.  No
Lender shall be permitted or required to

          (a)  make any Loan if, after giving effect thereto, an amount
     equal to the Dollar Amount of the aggregate outstanding principal amount
     of all Revolving Loans

               (i)  of all Lenders, together with the Dollar Amount of all
          outstanding Swing Loans and the Dollar Amount of all Letter of
          Credit Outstandings, would exceed the Commitment Amount, or

               (ii)  of such Lender, together with the Dollar Amount of its
          Percentage of the Dollar Amount of the principal amount of all
          Swing Loans and the Dollar Amount of its Percentage of all Letter
          of Credit Outstandings, would exceed such Lender's Percentage of
          the Commitment Amount; or

          (b)  issue (in the case of the Issuer), extend or participate in
     (in the case of each Lender) any Letter of Credit if, after giving
     effect thereto

               (i)  the Dollar Amount of all Letter of Credit Outstandings
          together with an aggregate amount equal to the Dollar Amount of
          the aggregate outstanding principal amount of all Loans would
          exceed the Commitment Amount, or

               (ii)  the Dollar Amount of such Lender's Percentage of all
          Letter of Credit Outstandings together with an aggregate amount
          equal to the Dollar Amount of the aggregate outstanding principal
          amount of all Revolving Loans of such Lender and such Lender's
          Percentage of the Dollar Amount of the aggregate principal amount
          of all Swing Loans would exceed such Lender's Percentage of the
          Commitment Amount.

     For the purposes of this Section 2.1.3, the Dollar Amount of any Loans
not denominated in Dollars shall be determined as of the most recent
Determination Date for each such Loan.

     SECTION 2.2.  Reduction of Commitment Amounts.  Simpson may, from time
to time on any Business Day, voluntarily reduce the amount of the Commitment
Amount; provided, however, that Simpson shall simultaneously reduce the amount
of Commitment Amount (as such term is defined in the Companion Agreement)
under the Companion Agreement by an equal amount; provided, further, that the
Commitment Amount shall not be reduced to an amount less than the Outstandings
(after giving effect to any concurrent repayment of Loans); and provided
further, that all such reductions shall require at least 5 Business Days'
prior notice to the Agent and be permanent, and any partial reduction of such
Commitment Amount shall be in a minimum amount of $1,000,000 and in an
integral multiple of $250,000.

     SECTION 2.3.  Borrowing Procedure.  By delivering a Borrowing Request
to the Agent on or before 11:00 A.M., New York time, on a Business Day,
Simpson may from time to time irrevocably request (on not less than three nor
more than five Business Days' notice with respect to a Eurocurrency Rate Loan,
and not less than one nor more than five Business Days' notice with respect to
Prime Rate Loan) that a Borrowing of Revolving Loans be made to the Borrower
specified by Simpson in an Available Currency, if in Dollars, in a minimum
amount of $2,000,000 and an integral multiple of $100,000 or if in another
Available Currency, in a minimum amount of the Dollar Amount of $2,000,000 and
an integral multiple of 100,000 units of such Available Currency, or in the
unused amount of the applicable Commitment.  On the terms and subject to the
conditions of this Agreement, each Borrowing shall be comprised of the same
Rate Option of Loans (and, in the case of Eurocurrency Rate Loans, the same
Available Currency), and shall be made on the Business Day, specified in such
Borrowing Request.  The proceeds of each Borrowing shall be advanced to the
Borrower specified in the applicable Borrowing Request.  On or before 10:00
A.M., New York time, on such Business Day each Lender shall deposit with the
Agent same day funds in the applicable Available Currency in an amount equal
to such Lender's Percentage of the requested Borrowing.  Such deposit will be
made to such accounts which the Agent shall specify from time to time by
notice to the Lenders.  To the extent funds are received from the Lenders, the
Agent shall make such funds available to the Borrower specified by Simpson by
wire transfer to such accounts as Simpson shall have specified in its
Borrowing Request.  No Lender's obligation to make any Loan shall be affected
by any other Lender's failure to make any Loan.

     SECTION 2.4.  Continuation and Conversion Elections.  By delivering a
Continuation/Conversion Notice to the Agent on or before 11:00 A.M., New York
time, on a Business Day, Simpson may from time to time irrevocably elect (on
not less than three nor more than five Business Days' notice with respect to a
conversion into or a continuation of a Eurocurrency Loan to a Borrower
specified by Simpson and not less than one nor more than five Business Days'
notice with respect to a conversion into Prime Rate Loan) that all, or any
portion in an aggregate minimum amount, if in Dollars of $2,000,000 and an
integral multiple of $100,000 or in the case of an Available Currency other
than Dollars, in an aggregate minimum amount of the Dollar Amount of
$2,000,000 and an integral multiple of 100,000 units of such currency, of any
Revolving Loans be, in the case of Prime Rate Loans, converted into
Eurocurrency Rate Loans or, in the case of Eurocurrency Rate Loans be
converted into Prime Rate Loans or Eurocurrency Rate Loans in another
Available Currency or continued as Eurocurrency Rate Loans in the same
currency.  In the absence of delivery of a Continuation/ Conversion Notice
with respect to any Revolving Loan constituting a Eurocurrency Rate Loan by
11:00 A.M. New York time at least three Business Days before the last day of
the then current Interest Period with respect thereto, such Eurocurrency Rate
Loan shall, on such last day, automatically convert to a Eurocurrency Rate
Loan in the same currency having an Interest Period equal to the shorter of
(i) one month and (ii) the number of days in the period from and including
such last day to but excluding the Commitment Termination Date; provided that
such period determined under this clause (ii) is acceptable to the Agent,
otherwise the Loan shall become due and payable.  Each such conversion or
continuation shall be prorated among the applicable outstanding Loans of such
Borrower to all Lenders, and when any Default has occurred and is continuing,
no portion of the outstanding principal amount of any Loans may be continued
as, or be converted into, Eurocurrency Rate Loans.

     SECTION 2.5.  Funding.  Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert Eurocurrency Rate Loans hereunder by
causing one of its foreign branches or  Affiliates (or an international
banking facility created by such Lender) to make or maintain such Eurocurrency
Rate Loan; provided, however, that such Eurocurrency Rate Loan shall
nonetheless be deemed to have been made and to be held by such Lender, and the
obligation of the Borrowers to repay such Eurocurrency Rate Loan shall
nevertheless be to such Lender for the account of such foreign branch,
Affiliate or international banking facility.  In addition, the Borrowers
hereby consent and agree that, for purposes of any determination to be made
for purposes of Section 5.1, 5.2, 5.3 or 5.4, it shall be conclusively assumed
that each Lender elected to fund all Eurocurrency Rate Loans by purchasing
deposits, in the interbank eurocurrency market having a maturity corresponding
to the Interest Period for such Loan and bearing an interest rate equal to the
Eurocurrency Rate for such Loan.

     SECTION 2.6.  Notes.  The Revolving Loans of each Lender to each
Borrower shall be evidenced by a Note of such Borrower, payable to the order
of such Lender in an amount equal to the Lender's Revolving Loans.  Each
Lender shall record in its records, or at its option on the schedule attached
to its applicable Note, the date, amount and Available Currency of each Loan
made by such Lender thereunder, each repayment or prepayment thereof, and the
dates on which the Interest Period for such Loan shall begin and end.  The
aggregate unpaid principal amount so recorded shall be rebuttable presumptive
evidence of the principal amount owing and unpaid on such Note.  The failure
to so record or any error in so recording any such amount shall not, however,
limit or otherwise affect the obligations of any Borrower hereunder or under
any Note to repay the principal amount of each Revolving Loan, together with
all interest accruing thereon.

     SECTION 2.7.  Swing Line Commitment.  From time to time on any Business
Day occurring prior to the Commitment Termination Date, the Swing Lender
agrees to make loans to Simpson (each such loan, a "Swing Loan") in an
aggregate principal amount not to exceed $10,000,000.  All Swing Loans shall
be in Dollars.  On the terms and subject to the conditions hereof, Simpson may
from time to time borrow, prepay and reborrow Swing Loans. 

     SECTION 2.8.  Borrowing Procedure   Swing Loans.  By delivering a
Borrowing Request to the Swing Lender and the Agent on or before 1:00 p.m.,
New York time, on a proposed Borrowing Date, Simpson may from time to time
irrevocably request that a Borrowing be made in a minimum amount of $2,000,000
and an integral multiple of $100,000.  On or before 4:00 P.M., Chicago time,
on such Borrowing Date the Swing Lender shall deposit with the Agent same day
funds in an amount equal to the requested Borrowing.  Such deposit will be
made to such accounts which the Agent shall specify from time to time by
notice to the Swing Lender.  To the extent funds are received from the Swing
Lender, the Agent shall make such funds available to Simpson by wire transfer
to such accounts as Simpson shall have specified in its Borrowing Request.

     SECTION 2.9.  Refunding of Swing Loans.  The Swing Lender may, at any
time later than five Business Days after the Borrowing Date of a Swing Loan,
in its sole and absolute discretion, on behalf of Simpson (which hereby
irrevocably directs the Swing Lender to act on its behalf), request each
Lender to make a Revolving Loan in Dollars in an amount equal to such Lender's
Percentage of the Dollar Amount of the principal amount of the Swing Loans
outstanding on the date such notice is given.  Unless any of the events
described in Section 9.1.9 shall have occurred (in which event the procedures
of Section 2.10 shall apply), and regardless of whether the conditions
precedent set forth in this Agreement to the making of a Revolving Loan are
then satisfied or the aggregate amount of such Revolving Loans is not in the
minimum or integral amount otherwise required hereunder, each Lender shall
make the proceeds of its Revolving Loan available to the Agent for the account
of the Swing Lender at 10:00 A.M. Chicago time in immediately available funds
on the Business Day next succeeding the date such notice is given.  The
proceeds of such Revolving Loans shall be in Dollars and shall be immediately
applied to repay the outstanding Swing Loans.  All Revolving Loans made
pursuant to this Section 2.9 shall be in Dollars and shall be Prime Rate Loans
(but, subject to the other provisions of this Agreement, may be converted to
Eurocurrency Rate Loans).

     SECTION 2.10.  Participations in Swing Loans.  (a)  If an event
described in Section 9.1.9 occurs (or for any reason the Lenders may not make
Revolving Loans pursuant to Section 2.9), each Lender will, upon notice from
the Agent, purchase from the Swing Lender (and the Swing Lender will sell to
each such Lender) an undivided participation interest in all outstanding Swing
Loans in an amount equal to its Percentage of the outstanding principal amount
of the Swing Loans (and each Lender will immediately transfer to the Agent,
for the account of the Swing Lender, in immediately available funds, the
amount of its participation).  

     (b)  Whenever, at any time after the Swing Lender has received payment
for any Lender's participation interest in the Swing Loans pursuant to Section
2.10(a), the Swing Lender receives any payment on account thereof, the Swing
Lender will distribute to the Agent for the account of such Lender its
participation interest in such amount (appropriately adjusted, in the case of
interest payments, to reflect the period of time during which such Lender's
participation interest was outstanding and funded) in like funds as received;
provided, however, that in the event that such payment received by the Swing
Lender is required to be returned, such Lender will return to the Agent for
the account of the Swing Lender any portion thereof previously distributed by
the Swing Lender to it in like funds as such payment is required to be
returned by the Swing Lender.

     SECTION 2.11.  Swing Loan Participation Obligations Unconditional.  (a) 
Each Lender's obligation to make Revolving Loans pursuant to Section 2.9
and/or to purchase participation interests in Swing Loans pursuant to Section
2.10 shall be absolute and unconditional and shall not be affected by any
circumstance whatsoever, including (a) any set-off, counterclaim, recoupment,
defense or other right which such Lender may have against the Swing Lender,
Simpson or any other Person for any reason whatsoever; (b) the occurrence or
continuance of an Event of Default; (c) any adverse change in the condition
(financial or otherwise) of Simpson or any other Person; (d) any breach of
this Agreement by Simpson or any other Lender; (e) any inability of Simpson to
satisfy the conditions precedent to borrowing set forth in this Agreement on
the date upon which any Swing Loan is to be refunded or any participation
interest therein is to be purchased; or (f) any other circumstance, happening
or event whatsoever, whether or not similar to any of the foregoing.

     (b)  Notwithstanding the provisions of subsection 2.11(a), no Lender
shall be required to make any Revolving Loan to Simpson to refund a Swing Loan
pursuant to Section 2.9 or to purchase a participation interest in a Swing
Loan pursuant to Section 2.10 if, prior to the making by the Swing Lender of
such Swing Loan, the Swing Lender received written notice (i) from a Lender
specifying that such Lender believes in good faith that one or more of the
conditions precedent to the making of such Swing Loan were not satisfied and,
in fact, such conditions precedent were not satisfied at the time of the
making of such Swing Loan or (ii) from Simpson that a Default has occurred and
is continuing; provided that the obligation of such Lender to make such
Revolving Loans and to purchase such participation interests shall be
reinstated upon the earlier to occur of (x) the date on which such Lender or
Simpson, as applicable, notifies the Swing Lender that its prior notice has
been withdrawn and (y) the date on which all conditions precedent to the
making of such Swing Loan have been satisfied (or waived by the Required
Lenders or all Lenders, as applicable).

     SECTION 2.12.  Conditions to Swing Loans.  Notwithstanding any other
provision of this Agreement, the Swing Lender shall not be obligated to make
any Swing Loan if a Default exists or would result therefrom.

     SECTION 2.13.  Swing Note.  The Swing Loans shall be evidenced by the
Swing Note of Simpson, payable to the order of the Swing Lender in an amount
equal to the Swing Loans.  The Swing Lender shall record in its records, or at
its option on the schedule attached to such Swing Note, the date and amount of
each Swing Loan and each repayment or prepayment thereof.  The aggregate
unpaid principal amount so recorded shall be rebuttable presumptive evidence
of the principal amount owing and unpaid on such Swing Note.  The failure to
so record or any error in so recording any such amount shall not, however,
limit or otherwise affect the obligations of Simpson hereunder or under the
Swing Note to repay the principal amount of each Swing Loan, together with all
interest accruing thereon.

     SECTION   2.14.   Stated Maturity Date Extension.  (a) Simpson may,
by notice to the Agent given not more than 60 days and not less than 45 days
prior to the scheduled Stated Maturity Date (the "Extension Request Date"),
request that the Lenders extend the Stated Maturity Date for 364 days from the
then scheduled Stated Maturity Date.  The Agent shall notify the Lenders of
its receipt of any notice given pursuant to this Section 2.14(a) within two
Business Days after the Agent's receipt thereof.  Each Lender (a "Consenting
Lender") may, by irrevocable notice to Simpson and the Agent delivered to
Simpson and the Agent not later than 30 days after the Extension Request Date
(the "Consent Period"), consent to such extension of the Stated Maturity Date,
which consent may be given or withheld by each Lender in its absolute and sole
discretion.  No extension shall be effective (i) unless consented to by
Lenders holding at least 66 % of the Commitments and (ii) if as of the Stated
Maturity Date, prior to the effectiveness of the extension, (i) any
representation or warranty set forth in Article VII hereof shall not be true
and correct with the same effect as if then made or (ii) any Default shall
have occurred and be continuing.

     (b)  Withdrawing Lenders.  No extension pursuant to Section 2.14(a)
shall be effective with respect to a Lender that either (i) by a notice (a
"Withdrawal Notice") delivered to Simpson and the Agent, declines to consent
to such extension or (ii) has failed to respond to Simpson and the Agent
within the Consent Period (each such Lender giving a Withdrawal Notice or
failing to respond in a timely manner being "Withdrawing Lender").

     (c)  Replacement of Withdrawing Lender.  Simpson shall have the right
during the period following the end of the Consent Period until the then
scheduled Stated Maturity Date to replace the Withdrawing Lender with an
existing Lender or a new Lender who consents to the extension of the Stated
maturity Date (a "Replacement Lender"), in the case of a new Lender, with the
prior written consent of the Agent, which consent shall not be unreasonably
withheld or delayed.  In the event Simpson has not replaced the Withdrawing
Lender within said period, the Stated Maturity Date shall not be extended.

     (d)  Assignment by Withdrawing Lender.  A Withdrawing Lender shall be
obliged, at the request of Simpson and subject to the Withdrawing Lender
receiving payment in full of all amounts owing to it under this Agreement
concurrently with the effectiveness of an assignment, to assign, without
recourse or warranty and pursuant to the terms of Section 11.11.1 hereof, all
of its rights and obligations hereunder to any Replacement Lender nominated by
the Borrower and willing to accept such assignment provided that if the
Replacement Lender or the Withdrawing Lender shall suffer any loss as a result
of such assignment during an Interest Period, Simpson shall reimburse such
Lender therefor.  The amount of any such loss shall be certified to Simpson by
such Lender, which certificate shall be conclusive absent manifest error.

     (e)  Scheduled Stated Maturity Date.  If the scheduled Stated Maturity
Date shall have been extended in respect of Consenting Lenders and any
Replacement Lender in accordance with Section 2.14, all references herein and
in any Note to the "Stated Maturity Date" shall refer to the Stated Maturity
Date as so extended.

                           ARTICLE III

            REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1.  Repayments and Prepayments.  The Borrowers shall repay in
full the unpaid principal amount of each Loan upon the Stated Maturity Date.

          (a)  Prior thereto, any Borrower may, from time to time on any
     Business Day, make a voluntary prepayment, in whole or in part without
     penalty or premium, of the outstanding principal amount of any Loans;
     provided, however, that

               (i)  any such prepayment shall be made to the Agent and
          shall be applied to Loans as the prepaying Borrower may specify
          and on a pro rata basis to the accounts of Loans of the same Rate
          Option and having the same Interest Period of all Lenders;

               (ii)  no such prepayment of any Eurocurrency Rate Loan may
          be made on any day other than the last day of the Interest Period
          for such Loan;

               (iii)  all such voluntary prepayments shall require at least
          three but no more than five Business Days' prior written notice to
          the Agent which notice shall be irrevocable once given; and

               (iv)  all such voluntary partial prepayments shall be in an
          aggregate minimum Dollar Amount of $2,000,000 and an integral
          multiple of 100,000 units of the Available Currency;

          (b)  In addition, the Borrowers shall, on each date when any
     reduction in the Commitment Amount shall become effective, including
     pursuant to Section 2.2, make a mandatory prepayment of outstanding
     Loans to the Agent equal to the excess, if any, of the aggregate
     Outstandings over the Commitment Amount as so reduced; 

          (c)  In addition, the Borrowers shall, on each Determination Date
     for any Borrowing of Eurocurrency Loans  on which the Dollar Amount of
     the Outstandings of the Borrowers exceed (as the result of fluctuations
     in applicable foreign exchange rates or otherwise) the then Commitment
     Amount, make a mandatory repayment to the Agent of Loans outstanding in
     an aggregate Dollar Amount equal to the excess of

               (x)  the aggregate Outstandings; over

               (y)  the then Commitment Amount;

          (d)  Each Borrower shall, immediately upon any acceleration of the
     Stated Maturity Date of any Loans pursuant to Section 9.2 or
     Section 9.3, repay all Loans, unless, pursuant to Section 9.3, only a
     portion of all Loans is so accelerated.

Each prepayment of any Loans made pursuant to this Section shall be without
premium or penalty, except as may be required by Section 5.4.  No voluntary
prepayment of principal of any Loans shall cause a reduction in the Commitment
Amount.

     SECTION 3.2.  Interest Provisions.  Interest on the outstanding
principal amount of Loans shall accrue and be payable in the applicable
Available Currency in accordance with this Section 3.2.

     SECTION 3.2.1.  Rates.  Pursuant to an appropriately delivered
Borrowing Request or Continuation/Conversion Notice, the applicable Borrower
may elect that Loans comprising a Borrowing accrue interest at a rate per
annum:

          (a)  on that portion of the Loans maintained from time to time as
     a Prime Rate Loan, equal to the sum of the Prime Rate from time to time
     in effect plus the applicable Margin; and

          (b)  on that portion of the Loans maintained as a Eurocurrency
     Rate Loan, during each Interest Period applicable thereto, equal to the
     sum of the applicable Eurocurrency Rate (Reserve Adjusted) for such
     Interest Period plus the applicable Margin.
     
     SECTION 3.2.2.  Post-Maturity Rates.  After the date any principal
amount of any Loan is due and payable (whether on the Stated Maturity Date or
upon acceleration), or after any other monetary Obligation of any Borrower
shall have become due and payable, the Borrowers agree to pay, but only to the
extent permitted by law, interest (after as well as before judgment) on Prime
Rate Loans at a rate per annum equal to the Prime Rate plus a margin of 2% and
on Eurocurrency Rate Loans at a rate per annum equal to 2% in excess of the
rate otherwise applicable until the end of the then applicable Interest Period
and thereafter at a rate equal to 2.75% per annum on the Eurocurrency Rate
(Reserve Adjusted) for Interest Periods not to exceed one month as determined
by the Agent; provided that any Eurocurrency Rate Loan denominated in Dollars
shall convert to a Prime Rate Loan at the end of the applicable Interest
Period. 

     SECTION 3.2.3.  Payment Dates.  Interest accrued on each Loan shall be
payable, without duplication:

          (a)  on the Stated Maturity Date therefor;

          (b)  on the date of any payment or prepayment of any Eurocurrency
     Rate Loans, in whole or in part, of principal outstanding on such
     Eurocurrency Rate Loan;

          (c)  with respect to Prime Rate Loans, on each Quarterly Payment
     Date occurring after the date of the initial Borrowing hereunder;

          (d)  with respect to Eurocurrency Rate Loans, on the last day of
     each applicable Interest Period (and, if such Interest Period shall
     exceed three months, on a date three months after the commencement of
     said Interest Period, or if not a Business Day, on the next Business Day
     unless said next Business Day is in the next calendar month then on the
     preceding Business Day); and

          (e)  on that portion of any Loans the Stated Maturity Date of
     which is accelerated pursuant to Section 9.2 or Section 9.3, immediately
     upon such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount is due and
payable (whether on the Stated Maturity Date, upon acceleration or otherwise)
shall be payable by the applicable Borrower upon demand.

     SECTION 3.3.  Fees.  The Borrowers agree to pay the fees set forth in
this Section 3.3.  All such fees shall be non-refundable.

     SECTION 3.3.1.  Commitment Fee.

          (a)  Simpson agrees to pay to the Agent for the account of each
     Lender, for the period (including any portion thereof when its
     Commitment is suspended by reason of the Borrowers' inability to satisfy
     any condition of Article VI) commencing on the Effective Date and
     continuing through the Commitment Termination Date, a commitment fee on
     such Lender's Percentage of the average daily Dollar Amount of the
     unused portion of the Loan Commitment Availability at the rate of 0.10%
     per annum;

          (b)  For purposes of determining the commitment fee, the average
     daily Dollar Amount of all outstanding Loans and the unused portion of
     the Loan Commitment Availability shall be determined as of each
     applicable Determination Date; and

          (c)  Such fee shall be payable in Dollars in immediately available
     funds in arrears on each Quarterly Payment Date.

     SECTION 3.3.2.  Arrangement Fee; Agent's Fee.  Simpson agrees to pay to
the Agent for its own account, a non-refundable arrangement fee, and,
thereafter, a non-refundable annual fee, in such amounts and payable at such
times as has been agreed upon between the Agent and Simpson in the fee letter
dated April 4, 1997 (as amended from time to time).

     SECTION 3.3.3.  Letter of Credit Face Amount Fee.  The applicable
Borrower agrees to pay to the Agent, for the account of the Lenders, a fee for
each Letter of Credit issued on the application of such Borrower for the
period from and including the date of the issuance of such Letter of Credit to
(but not including) the date upon which such Letter of Credit expires, at a
per annum rate equal to the applicable Margin of the face amount of such
Letter of Credit (which face amount shall be reduced by any reductions in such
Letters of Credit pursuant to Section 4.1(d) hereof).  Such fee shall be
payable in immediately available funds in advance on the date of issuance of
each Letter of Credit and on each Quarterly Payment Date thereafter.  No
portion of such fee shall be refunded after payment.

     SECTION 3.3.4.  Letter of Credit Fronting Fee.  The applicable Borrower
agrees to pay to the Issuer for its own account a fronting fee for each Letter
of Credit issued on the application of such Borrower for the period from and
including the date of the issuance of such Letter of Credit to (but not
including) the date upon which each Letter of Credit expires, of 0.02% (in the
case of a standby Letter of Credit) or 0.05% (in the case of a commercial
Letter of Credit) of the face amount of such Letter of Credit (which face
amount shall be reduced by any reductions in such Letters of Credit pursuant
to Section 4.1(c) hereof).  Such fee shall be payable in immediately available
funds on the date of issuance of such Letter of Credit.

     SECTION 3.3.5.  Letter of Credit Administrative Fee.  The Borrowers
agree to pay to the Agent, for the account of the Issuer, the amounts set
forth in Section 4.3.


                            ARTICLE IV

                        LETTERS OF CREDIT

     SECTION 4.1.  Issuance Requests.  By delivering to the Agent and the
Issuer an Issuance Request on or before 10:00 A.M., New York time, any
Borrower may request, from time to time prior to the Commitment Termination
Date and on not less than three nor more than ten Business Days' notice, that
the Issuer issue an irrevocable letter of credit in substantially the form of
Exhibit D hereto, or in such other form as may be requested by a Borrower and
approved by the Issuer (each a "Letter of Credit"), in support of financial
obligations of such Borrower incurred in such Borrower's ordinary course of
business and which are described in such Issuance Request.  Upon receipt of an
Issuance Request, the Agent shall promptly notify the Lenders thereof.  Each
Letter of Credit shall by its terms:

          (a)  be issued in Dollars;

          (b)  be issued in a Stated Amount which does not exceed (or would
          not exceed) the then Letter of Credit Availability;

          (c)  be stated to expire on a date (its "Stated Expiry Date") no
     later than the earlier of (i) one year from the date of issuance, or
     (ii) the Commitment Termination Date; and

          (d)  on or prior to its Stated Expiry Date

               (i)  terminate immediately upon notice to the Issuer
          thereof from the beneficiary thereunder that all obligations
          covered thereby have been terminated, paid, or otherwise satisfied
          in full, or

               (ii)  reduce in part immediately and to the extent the
          beneficiary thereunder has notified the Issuer thereof that the
          obligations covered thereby have been paid or otherwise satisfied
          in part.

So long as no Default has occurred and is continuing and subject to the
conditions set forth in this Agreement, by delivery to the Issuer and the
Agent of an Issuance Request at least three but not more than ten Business
Days prior to the Stated Expiry Date of any Letter of Credit, such Borrower
may request the Issuer to extend the Stated Expiry Date of such Letter of
Credit for an additional period not to extend beyond the Commitment
Termination Date.

     SECTION 4.2.  Issuances and Extensions.  On the terms and subject to
the conditions of this Agreement (including Article VI), the Issuer shall
issue Letters of Credit, and extend the Stated Expiry Dates of outstanding
Letters of Credit, in accordance with the Issuance Requests made therefor. 
The Issuer will make available the original of each Letter of Credit which it
issues in accordance with the Issuance Request therefor to the beneficiary
thereof (and will promptly notify each of the Lenders of the issuance) and
will notify the beneficiary under any Letter of Credit of any extension of the
Stated Expiry Date thereof.

     SECTION 4.3.  Expenses.  Each Borrower agrees to pay to the Agent for
the account of the Issuer with respect to each Letter of Credit issued on the
application of such Borrower all standard administrative expenses of the
Issuer in connection with the issuance, maintenance, modification (if any) and
administration of each Letter of Credit issued by the Issuer at the request of
the Borrower upon demand from time to time.

     SECTION 4.4.  Other Lenders' Participation.  Each Letter of Credit
issued pursuant to Section 4.2 shall, effective upon its issuance and without
further action, be issued on behalf of all Lenders (including the Issuer
thereof) pro rata according to their respective Percentages.  Each Lender
shall, to the extent of its Percentage (unless the Issuer shall have received
written notice that the conditions precedent to the issuance of such Letter of
Credit had not occurred prior to such issuance), be deemed irrevocably to have
participated in the issuance of such Letter of Credit and shall be responsible
to reimburse promptly the Issuer thereof for Reimbursement Obligations which
have not been reimbursed by the applicable Borrower in accordance with
Section 4.5, or which have been reimbursed by the applicable Borrower but must
be returned, restored or disgorged by the Issuer for any reason, and each
Lender shall, to the extent of its Percentage, be entitled to receive from the
Agent a ratable portion of the letter of credit fees received by the Agent
pursuant to Section 3.3.3, with respect to each Letter of Credit.  In the
event that the applicable Borrower shall fail to reimburse the Issuer, or if
for any reason Revolving Loans shall not be made to fund any Reimbursement
Obligation, all as provided in Section 4.5 and in an amount equal to the
amount of any drawing honored by the Issuer under a Letter of Credit issued by
it, or in the event the Issuer must for any reason return or disgorge such
reimbursement, the Issuer shall promptly notify each Lender of the
unreimbursed amount of such drawing and of such Lender's respective
participation therein.  Each Lender shall make available to the Issuer,
whether or not any Default shall have occurred and be continuing, an amount
equal to its respective participation in same day or immediately available
funds at the office of the Issuer specified in such notice not later than
10:00 A.M., New York time, on the Business Day after the date the Lenders are
notified by the Issuer.  In the event that any Lender fails to make available
to the Issuer the amount of such Lender's participation in such Letter of
Credit as provided herein, the Issuer shall be entitled to recover such amount
on demand from such Lender together with interest at the Federal Funds Rate
for three Business Days (together with such other compensatory amounts as may
be required to be paid by such Lender to the Agent pursuant to the Rules for
Interbank Compensation of the Council on International Banking or the
Clearinghouse Compensation Committee, as the case may be, as in effect from
time to time) and thereafter at the Prime Rate plus 2%.  Nothing in this
Section shall be deemed to prejudice the right of any Lender to recover from
the Issuer any amounts made available by such Lender to the Issuer pursuant to
this Section in the event that it is determined by a court of competent
jurisdiction that the payment with respect to a Letter of Credit by the Issuer
in respect of which payment was made by such Lender constituted gross
negligence or wilful misconduct on the part of the Issuer.  The Issuer shall
distribute to each other Lender which has paid all amounts payable by it under
this Section with respect to any Letter of Credit issued by the Issuer such
other Lender's Percentage of all payments received by the Issuer from the
applicable Borrower in reimbursement of drawings honored by the Issuer under
such Letter of Credit when such payments are received.

     SECTION 4.5.  Disbursements.  The Issuer will notify the applicable
Borrower and the Agent promptly of the presentment for payment of any Letter
of Credit, together with notice of the date (a "Disbursement Date") such
payment shall be made.  Subject to the terms and provisions of such Letter of
Credit, the Issuer shall make such payment to the beneficiary (or its
designee) of such Letter of Credit.  Prior to 10:00 A.M., New York time, on
the Disbursement Date, the applicable Borrower will reimburse the Issuer for
all amounts which it has disbursed under the Letter of Credit.  To the extent
the Issuer is not reimbursed in full in accordance with the third sentence of
this Section, the Borrower's Reimbursement Obligation shall accrue interest
(i) during the three days following the Disbursement Date at the Prime Rate
and (ii) thereafter at the Prime Rate plus a margin of 2% per annum, payable
on demand.  In the event the Issuer is not reimbursed by the applicable
Borrower on the Disbursement Date (other than upon a deemed Disbursement under
Section 4.7 when an actual Disbursement has not been made), or if the Issuer
must for any reason return or disgorge such reimbursement, the Lenders
(including the Issuer) shall, on the terms and subject to the conditions of
this Agreement, fund the Reimbursement Obligation therefor by making Revolving
Loans which shall be Prime Rate Loans (the applicable Borrower being deemed to
have given a timely Borrowing Request therefor for such amount); provided,
however, for the purpose of determining the availability of the Commitments to
make Revolving Loans immediately prior to giving effect to the application of
the proceeds of such Revolving Loans, such Reimbursement Obligation shall be
deemed not to be outstanding at such time.

     SECTION 4.6.  Reimbursement.  The obligation of each Borrower (a
"Reimbursement Obligation") under Section 4.5 to reimburse the Issuer with
respect to each Disbursement (including interest thereon) with respect to each
Letter of Credit issued on such Borrower's application, and each Lender's
obligation to make participation payments in each drawing which has not been
reimbursed by the Borrower, shall be absolute and unconditional under any and
all circumstances and irrespective of any setoff, counterclaim, or defense to
payment which the applicable Borrower may have or have had against any Lender
or any beneficiary of a Letter of Credit, including any defense based upon the
occurrence of any Default, any draft, demand or certificate or other document
presented under a Letter of Credit proving to be forged, fraudulent, invalid
or insufficient, the failure of any Disbursement to conform to the terms of
the applicable Letter of Credit (if, in the Issuer's opinion, such
Disbursement conforms to the terms of the applicable Letter of Credit, unless
such determination is the result of the Issuer's gross negligence or wilful
misconduct) or any non-application or misapplication by the beneficiary of the
proceeds of such Disbursement, or the legality, validity, form, regularity, or
enforceability of such Letter of Credit; provided, however, that nothing
herein shall adversely affect the right of the applicable Borrower to commence
any proceeding against the Issuer for any wrongful Disbursement made by the
Issuer under a Letter of Credit as a result of acts or omissions constituting
gross negligence or wilful misconduct on the part of the Issuer.

     SECTION 4.7.  Deemed Disbursements.  Upon the occurrence and during the
continuation of any Event of Default or the occurrence of the Commitment
Termination Date, an amount equal to that portion of Letter of Credit
Outstandings attributable to outstanding and undrawn Letters of Credit shall,
at the election of the Issuer acting on instructions from the Required
Lenders, and without demand upon or notice to the applicable Borrower, be
deemed to have been paid or disbursed by the Issuer under such Letters of
Credit (notwithstanding that such amount may not in fact have been so paid or
disbursed), and, upon notification by the Issuer to the Agent and the
applicable Borrower of its obligations under this Section, the applicable
Borrower shall be immediately obligated to reimburse the Issuer the amount
deemed to have been so paid or disbursed by the Issuer.  Any amounts so
received by the Issuer from the applicable Borrower pursuant to this Section
shall be held as collateral security for the repayment of the applicable
Borrower's obligations in connection with the Letters of Credit issued by the
Issuer.  At any time when such Letters of Credit shall terminate and all
Obligations of the Issuer are either terminated or paid or reimbursed to the
Issuer in full, the Obligations  under this Section shall be reduced
accordingly (subject, however, to reinstatement in the event any payment in
respect of such Letters of Credit is recovered in any manner from the Issuer),
and the Issuer will return to the Borrowers the excess, if any, of

          (a)  the aggregate amount deposited by the applicable Borrower
     with the Issuer and not theretofore applied by the Issuer to any
     Reimbursement Obligation or other Obligation  

over

          (b)  the aggregate amount of all Reimbursement Obligations to the
     Issuer pursuant to this Section, as so adjusted and other Obligations.

At such time when all Events of Default shall have been cured or waived or
when all Obligations of the Borrowers shall have been terminated, paid, or
otherwise satisfied in full, the Issuer shall return to the Borrowers all
amounts then on deposit with the Issuer pursuant to this Section.

     SECTION 4.8.  Nature of Reimbursement Obligations.  The Borrowers shall
assume all risks of the acts, omissions, or misuse of any Letter of Credit by
the beneficiary thereof.  Neither the Issuer nor any Lender (except to the
extent of its own gross negligence or wilful misconduct) shall be responsible
for:

          (a)  the form, genuineness, or legal effect of any Letter of
     Credit or the form, validity, sufficiency, accuracy, genuineness, or
     legal effect of any document submitted by any party in connection with
     the application for and issuance of a Letter of Credit, even if it
     should in fact prove to be in any or all respects invalid, insufficient,
     inaccurate, fraudulent, or forged;

          (b)  the form, validity, sufficiency, accuracy, genuineness, or
     legal effect of any instrument transferring or assigning or purporting
     to transfer or assign a Letter of Credit or the rights or benefits
     thereunder or proceeds thereof in whole or in part, which may prove to
     be invalid or ineffective for any reason;

          (c)  failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (d)  errors, omissions, interruptions, or delays in transmission
     or delivery of any messages, by mail, cable, telegraph, telex, or
     otherwise; or

          (e)  any loss or delay in the transmission or otherwise of any
     document or draft required in order to make a Disbursement under a
     Letter of Credit or of the proceeds thereof.

     SECTION 4.9.  Increased Costs; Indemnity.  If by reason of

          (a)  any change in applicable law, regulation, rule, decree or
     regulatory requirement or any change in the interpretation or
     application by any judicial or regulatory authority of any law,
     regulation, rule, decree or regulatory requirement, or

          (b)  compliance by the Issuer or any Lender with any direction,
     request or requirement (whether or not having the force of law) of any
     governmental or monetary authority, including Regulation D of the F.R.S.
     Board:

               (i)  the Issuer or any Lender shall be subject to any tax
          (other than taxes on net income and franchises), levy, charge or
          withholding of any nature or to any variation thereof or to any
          penalty with respect to the maintenance or fulfillment of its
          obligations under this Article IV, whether directly or by such
          being imposed on or suffered by the Issuer or any Lender;

               (ii)  any reserve, deposit or similar requirement is or
          shall be applicable, imposed or modified in respect of any Letters
          of Credit issued by the Issuer or participations therein purchased
          by any Lender; or

               (iii)  there shall be imposed on the Issuer or any Lender
          any other condition regarding this Article IV, any Letter of
          Credit or any participation therein;

and the result of the foregoing is directly or indirectly to increase the cost
to the Issuer or such Lender of issuing, making or maintaining any Letter of
Credit or of purchasing or maintaining any participation therein, or to reduce
any amount receivable in respect thereof by the Issuer or such Lender, then
and in any such case the Issuer or such Lender may, at any time after the
additional cost is incurred or the amount received is reduced, notify the
Borrower on whose application such Letter of Credit was issued thereof, and
such Borrower agrees to pay no later than three days after demand such amounts
as the Issuer or Lender may specify to be necessary to compensate the Issuer
or Lender for such additional cost or reduced receipt, together with interest
on such amount from the date due until payment in full thereof at a rate equal
at all times to the Prime Rate plus 2% per annum.  The determination by the
Issuer or Lender, as the case may be, of any amount due pursuant to this
Section, as set forth in a statement setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.  In addition to amounts
payable as elsewhere provided in this Article IV, the Borrower on whose
application such Letter of Credit was issued agrees to protect, indemnify, pay
and save the Issuer harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including
reasonable attorneys' fees and allocated costs of internal counsel) which the
Issuer may incur or be subject to as a consequence, direct or indirect, of

          (c)  the issuance of any Letter of Credit, other than as a result
     of the gross negligence or wilful misconduct of the Issuer as determined
     by a court of competent jurisdiction or other than with respect to the
     validity, sufficiency or accuracy of any Letter of Credit, or

          (d)  the failure of the Issuer to honor a drawing under any Letter
     of Credit requested by such Borrower as a result of any act or omission,
     whether rightful or wrongful, of any present or future de jure or de
     facto government or governmental authority.

     SECTION 4.10.  Uniform Customs.  Each Letter of Credit shall be subject
to the Uniform Customs and Practice for Documentary Credits, 1993 Revisions,
ICC Publication No. 500.


                           ARTICLE V

          CERTAIN EUROCURRENCY RATE AND OTHER PROVISIONS

     SECTION 5.1.  Eurocurrency Rate Lending Unlawful.  If any Lender shall
determine in good faith (which determination shall, upon notice thereof to the
Borrowers and the Lenders, be conclusive and binding) that the introduction of
or any change in or in the interpretation of any law makes it unlawful, or any
central bank or other governmental authority asserts that it is unlawful, for
such Lender to make, continue or maintain any Loan as, or to convert any Loan
into, a Eurocurrency Rate Loan of a certain Available Currency, the
obligations of all Lenders to make, continue, maintain or convert into any
such Loans shall, upon such determination, forthwith be suspended until such
Lender shall notify the Agent that the circumstances causing such suspension
no longer exist, and all Eurocurrency Rate Loans of such Available Currency
shall automatically convert into Prime Rate in an amount equal to the Dollar
Amount thereof at the end of the then current Interest Periods with respect
thereto or sooner, if required by such law or assertion.

     SECTION 5.2.  Deposits Unavailable.  If the Agent shall have determined
that

          (a)  deposits in the relevant Available Currency in the relevant
     amount and for the relevant Interest Period are not available to ABN in
     its relevant market; or

          (b)  by reason of circumstances affecting ABN's relevant market,
     adequate means do not exist for ascertaining the interest rate
     applicable hereunder to Eurocurrency Rate Loans of such type,

then, upon notice from the Agent to the Borrowers and the Lenders, the
obligations of all Lenders under Section 2.3 and Section 2.4 to make or
continue any Loans as, or to convert any Loans into, Eurocurrency Rate Loans
of such Available Currency shall forthwith be suspended until the Agent shall
notify the Borrower and the Lenders that the circumstances causing such
suspension no longer exist.

     SECTION 5.3.  Increased Eurocurrency Rate Loan Costs, etc.  Each
Borrower agrees to reimburse any Lender if, as a result of any change in any
law, regulation, treaty or directive, or in any regulatory interpretation or
application thereof or compliance by such Lender with any request or directive
(whether or not having the force of law) from any court or governmental
authority, agency or central bank

          (i)  the basis of taxation of payments to such Lender of the
     principal of or interest on any Eurocurrency Rate Loan (other than taxes
     imposed on the overall net income of such Lender by the jurisdiction in
     which such Lender has its principal office) is changed;

          (ii)  any reserve, special deposit or similar requirements against
     assets of, deposits with or for the account of, or credit extended by,
     such Lender are imposed, modified or deemed applicable; or

          (iii)  any other condition affecting this Agreement or any
     Eurocurrency Rate Loan is imposed on the interbank eurocurrency market;

and such Lender determines that, by reason thereof, the cost to such Lender of
making or maintaining any of the Eurocurrency Rate Loans is actually
increased, or the amount of any sum receivable by such Lender hereunder in
respect of any of the Eurocurrency Rate Loans is actually reduced; then the 
applicable Borrower shall pay to such Lender within three Business Days after
demand (which demand shall be accompanied by a statement setting forth the
basis for the calculation thereof but only to the extent not theretofore
provided to the applicable Borrower) such additional amount or amounts as will
compensate such Lender for such additional cost or reduction to the extent
such cost or reduction has not been provided for in the calculation of the
Eurocurrency Reserve Percentage.  Determinations by such Lender for purposes
of this section of the additional amounts required to compensate such Lender
in respect of the foregoing shall be rebuttably presumed to be correct.  

     SECTION 5.4.  Funding Losses.  In the event any Lender shall incur any
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a
Eurocurrency Rate Loan) as a result of

          (a)  any conversion or repayment or prepayment of the principal
     amount of any Eurocurrency Rate Loans on a date other than the scheduled
     last day of the Interest Period applicable thereto, whether pursuant to
     Section 3.1 or otherwise;

          (b)  any Loans not being made as Eurocurrency Rate Loans in
     accordance with the Borrowing Request therefor; or

          (c)  any Loans not being continued as, or converted into,
     Eurocurrency Rate Loans in accordance with the Continuation/Conversion
     Notice therefor,

then, the applicable Borrower agrees that upon the written notice of such
Lender (with a copy to the Agent), such Borrower shall pay directly to such
Lender upon demand such amount as will (in the reasonable determination of
such Lender) reimburse such Lender for such loss or expense.  Such written
notice (which shall include calculations in reasonable detail) shall, in the
absence of manifest error, be conclusive and binding on the Borrower.

     SECTION 5.5.  Increased Capital Costs.  If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority affects or would affect the amount of capital
required or expected to be maintained by any Lender or any Person controlling
such Lender, and such Lender determines (in its sole and absolute discretion)
that the rate of return on its or such controlling Person's capital as a
consequence of its Commitments, issuance of or participation in Letters of
Credit or the Loans made by such Lender is reduced to a level below that which
such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender, the Borrowers agree immediately to pay directly
to such Lender additional amounts sufficient to compensate such Lender or such
controlling Person for such reduction in rate of return.  A statement of such
Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrowers.  In determining such amount, such
Lender may use any method of averaging and attribution that it (in its sole
and absolute discretion) shall deem applicable.

     SECTION 5.6.  Taxes.  All payments by any of the Borrowers of principal
of, and interest on, the Loans and all other amounts payable hereunder shall
be made free and clear of and without deduction for any present or future
income, excise, stamp or franchise taxes and other taxes, fees, duties,
withholdings or other charges of any nature whatsoever imposed by any taxing
authority, but excluding franchise taxes and taxes imposed on or measured by
any Lender's net income or receipts (such non-excluded items being called
"Taxes").  In the event that any withholding or deduction from any payment to
be made by a Borrower hereunder is required in respect of any Taxes pursuant
to any applicable law, rule or regulation, then the applicable Borrower agrees
to

          (a)  pay directly to the relevant authority the full amount
     required to be so withheld or deducted;

          (b)  promptly forward to the Agent an official receipt or other
     documentation satisfactory to the Agent evidencing such payment to such
     authority; and

          (c)  pay to the Agent for the account of the Lenders such
     additional amount or amounts as is necessary to ensure that the net
     amount actually received by each Lender will equal the full amount such
     Lender would have received had no such withholding or deduction been
     required.

Moreover, if any Taxes are directly asserted against the Agent or any Lender
with respect to any payment received by the Agent or such Lender hereunder,
the Agent or such Lender may pay such Taxes and the applicable Borrower agrees
to promptly pay such additional amounts (including any penalties, interest or
expenses) as is necessary in order that the net amount received by such person
after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount such person would have received had not such
Taxes been asserted.

     If the applicable Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fail to remit to the Agent, for the account of
the respective Lenders, the required receipts or other required documentary
evidence, the applicable Borrower shall indemnify the Lenders for any
incremental Taxes, interest or penalties that may become payable by any Lender
as a result of any such failure.  For purposes of this Section 5.6, a
distribution hereunder by the Agent or any Lender to or for the account of any
Lender shall be deemed a payment by the Borrower.

     Upon the request of Simpson or the Agent, each Lender that is organized
under the laws of a jurisdiction other than the United States shall, prior to
the due date of any payments under the Notes, execute and deliver to Simpson
and the Agent, on or about the first scheduled payment date in each Fiscal
Year, one or more (as Simpson or the Agent may reasonably request) United
States Internal Revenue Service Forms 4224 or Forms 1001 or such other forms
or documents (or successor forms or documents), appropriately completed, as
may be applicable to establish the extent, if any, to which a payment to such
Lender is exempt from withholding or deduction of Taxes.

     Notwithstanding anything to the contrary herein, the Borrowers shall not
be responsible for any Taxes on the transfer by assignment or sale of a
participation of any interest herein, nor shall the liability of the Borrowers
under this Section 5.6 be increased by reason of any assignment or sale of a
participation, except upon any change in law arising after said assignment or
sale.

     SECTION 5.7.  Payments, Computations, etc.  

          (a)  Currency of Payments.  Each payment on account of an amount
     due from any Borrower hereunder shall be made by such Borrower to the
     Agent for the pro rata account of the Lenders entitled to receive such
     payment in the currency in which such amount is denominated and in such
     funds as are customary at the place and time of payment for the
     settlement of international payments in such currency.  Upon request,
     the Agent will give the applicable Borrower a statement showing the
     computation used in calculating such amount, which statement shall be
     conclusive in the absence of manifest error.  The obligation of the
     Borrowers to make each payment on account of such amount in the currency
     in which such amount is denominated shall not be discharged or satisfied
     by any tender, or any recovery pursuant to any judgment, which is
     expressed in or converted into any other currency, except to the extent
     such tender or recovery shall result in the actual receipt by the Agent
     of the full amount in the appropriate currency payable hereunder.  Each
     Borrower agrees that its obligation to make each payment on account of
     such amount in the currency in which such amount is denominated shall be
     enforceable as an additional or alternative claim for recovery in such
     currency of the amount (if any) by which such actual receipt shall fall
     short of the full amount of such currency payable hereunder, and shall
     not be affected by judgment being obtained for such amount.

          (b)  Conversion of Currencies.  If for the purpose of obtaining
     judgment in any court it is necessary to convert an amount in any
     currency due from the Borrowers hereunder (hereinafter called the
     "Original Currency") into another currency (hereinafter called the
     "Other Currency"), the rate of exchange which shall be applied shall, to
     the fullest extent permitted by applicable law, be that at which the
     Agent could purchase, in Chicago, Illinois, in accordance with normal
     banking procedures, the Original Currency with the Other Currency on the
     Business Day preceding that on which final judgment is given.  

          (c)  Remittance to Lenders; Basis for Payments.  The Agent shall
     promptly remit in same day funds to each Lender its share, if any, of
     such payments received by the Agent for the account of such Lender.  All
     interest and fees shall be computed on the basis of the actual number of
     days (including the first day but excluding the last day) occurring
     during the period for which such interest or fee is payable over a year
     comprised of 360 days (or, in the case of interest on Prime Rate Loan
     (other than when calculated with respect to the Federal Funds Rate) or
     Eurocurrency Rate Loans denominated in Pounds Sterling, 365 days or, if
     appropriate, 366 days).  Whenever any payment to be made shall otherwise
     be due on a day which is not a Business Day, such payment shall (except
     as otherwise required by clause (c) of the definition of the term
     "Interest Period" with respect to Eurocurrency Rate Loans) be made on
     the next succeeding Business Day and such extension of time shall be
     included in computing interest and fees, if any, in connection with such
     payment.

          (d)  Place of Payment.  All payments hereunder shall be made to
     Agent in immediately available funds prior to 10:00 A.M., Chicago time
     on the date due at its office at 335 Madison Ave., N.Y., N.Y. 10017, or
     at such other place as may be designated by the Agent to Simpson in
     writing.  Any payments received after such time shall be deemed received
     on the next succeeding Business Day.  The Agent may, but shall not be
     obligated to, charge the account of any Borrower for the payment when
     due of all amounts payable by such Borrower hereunder.

     SECTION 5.8.  Sharing of Payments.  If any Lender shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Loan (other than pursuant to the terms
of Sections 5.3, 5.4 and 5.5) or Letter of Credit in excess of its pro rata
share of payments then or therewith obtained by all Lenders, such Lender shall
purchase from the other Lenders such participations in Loans made by them
and/or Letters of Credit as shall be necessary to cause such purchasing Lender
to share the excess payment or other recovery ratably with each of them;
provided, however, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing Lender, the purchase
shall be rescinded and each Lender which has sold a participation to the
purchasing Lender shall repay to the purchasing Lender the purchase price to
the ratable extent of such recovery together with an amount equal to such
selling Lender's ratable share (according to the proportion of

          (a)  the amount of such selling Lender's required repayment to the
     purchasing Lender

to

          (b)  the total amount so recovered from the purchasing Lender)

of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered.  The Borrowers agree that any Lender
so purchasing a participation from another Lender pursuant to this Section
may, to the fullest extent permitted by law, exercise all its rights of
payment (including pursuant to Section  5.9) with respect to such
participation as fully as if such Lender were the direct creditor of the
applicable Borrower in the amount of such participation.  If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section applies, such Lender
shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders entitled
under this Section to share in the benefits of any recovery on such secured
claim.

     SECTION 5.9.  Setoff.  Each Lender shall, upon the occurrence of any
Default described in clauses (a) through (d) of Section 9.1.9 or any other
Event of Default, have the right to appropriate and apply to the payment of
the Obligations owing to it (whether or not then due), and (as security for
such Obligations) each Borrower hereby grants to each Lender a continuing
security interest in, any and all balances, credits, deposits, accounts or
moneys of each such Borrower then or thereafter maintained with or otherwise
held by such Lender; provided, however, that any such appropriation and
application shall be subject to the provisions of Section 5.8.  Each Lender
agrees promptly to notify the applicable Borrower and the Agent after any such
setoff and application made by such Lender; provided, however, that the
failure to give such notice shall not affect the validity of such setoff and
application.  The rights of each Lender under this Section are in addition to
other rights and remedies (including other rights of setoff under applicable
law or otherwise) which such Lender may have.

     SECTION 5.10.  Use of Proceeds.  The Borrowers shall use the proceeds
of each Borrowing to finance acquisitions and for general corporate purposes.

     notice or both, would give rise to liability under any Environmental
     Law.

     SECTION 7.8.  Litigation, Labor Controversies, etc.  There is no
pending or, to the knowledge of any Borrower, threatened litigation, action,
proceeding, or labor controversy affecting Simpson or its Subsidiaries, or any

Affiliates unless such arrangement or contract is fair and equitable to such
Borrower or such Subsidiary and is an arrangement or contract of the kind
which would be entered into by a prudent Person in the position of such
Borrower or such Subsidiary with a Person which is not one of its Affiliates.

terminated, whereupon the full unpaid amount of such Loans and other
Obligations which shall be so declared due and payable shall be and become
immediately due and payable, without further notice, demand or presentment,

                           ARTICLE X

                            THE AGENT

     SECTION 10.1.  Actions.  Each Lender hereby appoints ABN as its Agent
under and for purposes of this Agreement, the Notes and each other Loan
Document.  Each Lender authorizes the Agent to act on behalf of such Lender
under this Agreement, the Notes and each other Loan Document and, in the
absence of other written instructions from the Required Lenders received from
time to time by the Agent (with respect to which the Agent agrees that it will
comply, except as otherwise provided in this Section or as otherwise advised
by counsel), to exercise such powers hereunder and thereunder as are
specifically delegated to or required of the Agent by the terms hereof and
thereof, together with such powers as may be reasonably incidental thereto. 
Each Lender hereby indemnifies (which indemnity shall survive any termination
of this Agreement) the Agent, pro rata according to such Lender's Percentage,
from and against any and all liabilities, obligations, losses, damages,
claims, costs or expenses of any kind or nature whatsoever 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, the Notes and any other Loan
Document, including reasonable attorneys' fees, and as to which the Agent is
not reimbursed by the Borrowers; provided, however, that no Lender shall be
liable for the payment of any portion of such liabilities, obligations,
losses, damages, claims, costs or expenses which are determined by a court of
competent jurisdiction in a final proceeding to have resulted solely from the
Agent's gross negligence or wilful misconduct.  The Agent shall not be
required to take any action hereunder, under the Notes or under any other Loan
Document, or to prosecute or defend any suit in respect of this Agreement, the
Notes or any other Loan Document, unless it is indemnified hereunder to its
satisfaction.  If any indemnity in favor of the Agent shall be or become, in
the Agent's determination, inadequate, the Agent may call for additional
indemnification from the Lenders and cease to do the acts indemnified against
hereunder until such additional indemnity is given.

     SECTION 10.2.  Funding Reliance, etc.  Unless the Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 P.M., New
York time, on the Business Day prior to a Borrowing with respect to Borrowings
in Dollars and by 9:00 A.M., New York time, two Business Days prior to a
Borrowing in any other currency that such Lender will not make available the
amount which would constitute its Percentage of such Borrowing on the date
specified therefor, the Agent may assume that such Lender has made such amount
available to the Agent and, in reliance upon such assumption, make available
to the applicable Borrower a corresponding amount.  If and to the extent that
such Lender shall not have made such amount available to the Agent, such
Lender and the applicable Borrower agrees to repay the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date the Agent made such amount available to such Borrower to the
date such amount is repaid to the Agent, at the interest rate applicable at
the time to Loans comprising such Borrowing.

     SECTION 10.3.  Exculpation.  Neither the Agent nor any of its directors,
officers, employees or agents shall be liable to any Lender for any action
taken or omitted to be taken by it under this Agreement or any other Loan
Document, or in connection herewith or therewith, except for gross negligence
or wilful misconduct, nor responsible for any recitals or warranties herein or
therein, nor for the effectiveness, enforceability, validity or due execution
of this Agreement or any other Loan Document, nor to make any inquiry
respecting the performance by any Borrower of its obligations hereunder or
under any other Loan Document.  Any such inquiry which may be made by the
Agent shall not obligate it to make any further inquiry or to take any action. 
The Agent shall be entitled to rely upon advice of counsel concerning legal
matters and upon any notice, consent, certificate, statement or writing which
the Agent believes to be genuine and to have been presented by a proper
Person.

     SECTION 10.4.  Successor.  The Agent may resign as such at any time upon
at least 30 days' prior notice to the Borrowers and all Lenders, so long as a
successor Agent shall have been appointed as of the effectiveness of such
resignation.  If the Agent at any time shall resign, the Required Lenders may
appoint another Lender (with the consent of Simpson which shall not be
unreasonably withheld) as a successor Agent which shall thereupon become the
Agent hereunder.  If no successor Agent shall have been so appointed by the
Required Lenders within 30 days after the retiring Agent's giving notice of
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent (with the consent of Simpson which shall not be unreasonably
withheld), which shall be one of the Lenders or a commercial banking
institution organized under the laws of the U.S. (or any State thereof) or a
U.S. branch or agency of a commercial banking institution, and having a
combined capital and surplus of at least $500,000,000.  Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall be entitled to receive from the retiring Agent such documents of
transfer and assignment as such successor Agent may reasonably request, and
shall thereupon succeed to and become vested with all rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement.  After any
retiring Agent's resignation hereunder as the Agent, the provisions of

          (a)  this Article X shall inure to its benefit as to, and the
     Agent shall continue to be responsible hereunder for, any actions taken
     or omitted to be taken by it while it was the Agent under this
     Agreement; and

          (b)  Section 11.3, Section 11.4 and Section 11.5 shall continue to
     inure to its benefit.

The Borrowers shall not be responsible for payment of any costs related to the
resignation of the Agent and the substitution of a new Agent. The resigning
Agent shall pay to the successor Agent any portion of the Agent's annual fee
paid to it applicable to the period after the effectiveness of such
resignation.

     SECTION 10.5.  Loans or Letters of Credit Issued by ABN.  ABN shall have
the same rights and powers with respect to (x) the Loans made by it or any of
its Affiliates, (y) the Notes held by it or any of its Affiliates, and (z) its
participating interests in the Letters of Credit as any other Lender and may
exercise the same as if it were not the Agent.  ABN and its Affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with any Borrower or any Subsidiary or Affiliate of any Borrower as
if ABN were not the Agent hereunder.

     SECTION 10.6.  Credit Decisions.  Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrowers, this Agreement, the
other Loan Documents (the terms and provisions of which being satisfactory to
such Lender) and such other documents, information and investigations as such
Lender has deemed appropriate, made its own credit decision to extend its
Commitments.  Each Lender also acknowledges that it will, independently of the
Agent and each other Lender, and based on such other documents, information
and investigations as it shall deem appropriate at any time, continue to make
its own credit decisions as to exercising or not exercising from time to time 
any rights and privileges available to it under this Agreement or any other
Loan Document.

     SECTION 10.7.  Copies, etc.  The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the
Agent by any Borrower pursuant to the terms of this Agreement (unless
concurrently delivered to the Lenders by such Borrower).  The Agent will
distribute to each Lender such financial statements and compliance
certificates received by the Agent from any Borrower for distribution to the
Lenders by the Agent in accordance with the terms of this Agreement.
     
     SECTION 10.8.  Documentation Agent. Each Lender hereby appoints Comerica
Bank as Documentation Agent for the Lenders.  The Documentation Agent shall
have no rights, powers, obligations, liabilities, responsibilities or duties
under this Agreement other than those applicable to all Lenders as such. Each
Lender acknowledges that it has not relied and will not rely on the
Documentation Agent in deciding to enter into this Agreement or in taking or
not taking action hereunder.


                           ARTICLE XI

                     MISCELLANEOUS PROVISIONS

     SECTION 11.1.  Waivers, Amendments, etc.  The provisions of this
Agreement and of each other Loan Document may from time to time be amended,
modified or waived, if such amendment, modification or waiver is in writing
and consented to by Simpson and the Required Lenders; provided, however, that
no such amendment, modification or waiver which would:

          (a)  modify any requirement hereunder that any particular action
     be taken by all the Lenders or by the Required Lenders shall be
     effective unless consented to by each Lender;

          (b)  modify this Section 11.1, change the definition of "Required
     Lenders", increase any Commitment Amount or the Percentage of any
     Lender, reduce any fees described in Article III, or extend the
     Commitment Termination Date shall be made without the consent of each
     Lender and each holder of a Note;

          (c)  extend the due date for, or reduce the amount of, any
     scheduled repayment or prepayment of principal of or interest on any
     Loan (or reduce the principal amount of or rate of interest on any Loan)
     shall be made without the consent of the holder of that Note evidencing
     such Loan;

          (d)  affect adversely the interests, rights or obligations of the
     Issuer in its capacity as the Issuer shall be made without the consent
     of the Issuer; 

          (e)  affect adversely the interests, rights or obligations of the
     Agent in its capacity as the Agent shall be made without consent of the
     Agent; or

          (f)  change the definitions of "Available Currency",
     "Determination Date" or "Dollar Amount" without the consent of each
     Lender.
          
No failure or delay on the part of the Agent, any Lender or the holder of any
Note in exercising any power or right under this Agreement or any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such power or right preclude any other or further exercise
thereof or the exercise of any other power or right.  No notice to or demand
on any Borrower in any case shall entitle it to any notice or demand in
similar or other circumstances.  No waiver or approval by the Agent, any
Lender or the holder of any Note under this Agreement or any other Loan
Document shall, except as may be otherwise stated in such waiver or approval,
be applicable to subsequent transactions.  No waiver or approval hereunder
shall require any similar or dissimilar waiver or approval thereafter to be
granted hereunder.

     SECTION 11.2.  Notices.  All notices and other communications provided
to any party hereto under this Agreement or any other Loan Document shall be
in writing or by facsimile and addressed, delivered or transmitted to such
party at its address or facsimile number set forth below its signature hereto
or set forth in the Lender Assignment Agreement or at such other address or
facsimile number as may be designated by such party in a notice to the other
parties.  Any notice, if mailed and properly addressed with postage prepaid or
if properly addressed and sent by pre-paid courier service, shall be deemed
given when received; any notice, if transmitted by facsimile, shall be deemed
given when transmitted.  Any notice to a Borrower other than Simpson shall
also be sent to Simpson.

     SECTION 11.3.  Payment of Costs and Expenses.  Simpson agrees to pay on
demand all reasonable out-of-pocket expenses of the Agent (including the
reasonable fees and out-of-pocket expenses of counsel to the Agent and of
local counsel, if any, who may be retained by counsel to the Agent) in
connection with

          (a)  the negotiation, preparation, execution and delivery of this
     Agreement and of each other Loan Document, including schedules and
     exhibits, and any amendments, waivers, consents, supplements or other
     modifications to this Agreement or any other Loan Document as may from
     time to time hereafter be required, whether or not the transactions
     contemplated hereby are consummated; and

          (b)  the preparation and review of the form of any document or
     instrument relevant to this Agreement or any other Loan Document.

Simpson further agrees to pay, and to save the Agent and the Lenders harmless
from all liability for, any stamp or other taxes which may be payable in
connection with the execution or delivery of this Agreement, the borrowings
hereunder, the issuance of the Notes, the issuance of the Letters of Credit,
or any other Loan Documents.  Simpson agrees to reimburse the Agent and each
Lender upon demand for all reasonable out-of-pocket expenses (including
attorneys' fees and legal expenses) incurred by the Agent or such Lender in
connection with the enforcement of any Obligations.

     SECTION 11.4.  Indemnification.  In consideration of the execution and
delivery of this Agreement by each Lender and the extension of the
Commitments, Simpson hereby indemnifies, exonerates and holds harmless the
Agent, the Issuer and each Lender and each of their respective officers,
directors, employees and agents (collectively, the "Indemnified Parties") free
and harmless from and against any and all actions, causes of action, suits,
losses, costs, liabilities and damages, and expenses incurred in connection
therewith (irrespective of whether any such Indemnified Party is a party to
the action for which indemnification hereunder is sought), including
reasonable attorneys' fees and disbursements (collectively, the "Indemnified
Liabilities"), incurred by the Indemnified Parties or any of them as a result
of, or arising out of, or relating to

          (a)  any transaction financed or to be financed in whole or in
     part, directly or indirectly, with the proceeds of any Loan or the use
     of any Letter of Credit;

          (b)  the entering into and performance of this Agreement and any
     other Loan Document by any of the Indemnified Parties;

          (c)  any investigation, litigation or proceeding related to any
     acquisition or proposed acquisition by any Borrower or any of its
     Subsidiaries of all or any portion of the stock or assets of any Person,
     whether or not the Agent or such Lender is party thereto;

          (d)  any investigation, litigation or proceeding related to any
     environmental cleanup, audit, compliance or other matter relating to the
     protection of the environment or the Release by any Borrower or any of
     its Subsidiaries of any Hazardous Material; or

          (e)  the presence on or under, or the escape, seepage, leakage,
     spillage, discharge, emission, discharging or releases from, any real
     property owned or operated by any Borrower or any Subsidiary thereof of
     any Hazardous Material (including any losses, liabilities, damages,
     injuries, costs, expenses or claims asserted or arising under any
     Environmental Law), regardless of whether caused by, or within the
     control of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's
gross negligence or wilful misconduct.  If and to the extent that the
foregoing undertaking may be unenforceable for any reason, Simpson hereby
agrees to make the maximum contribution to the payment and satisfaction of
each of the Indemnified Liabilities which is permissible under applicable law.

     SECTION 11.5.  Survival.  The obligations of the Borrower under
Sections 5.3, 5.4, 5.5, 5.6, 11.3, and 11.4, and the obligations of the
Lenders under Section 10.1, shall in each case survive any termination of this
Agreement, the payment in full of all Obligations and the termination of all
Commitments.  The representations and warranties made by the Borrower in this
Agreement and in each other Loan Document shall survive the execution and
delivery of this Agreement and each such other Loan Document.

     SECTION 11.6.  Severability.  Any provision of this Agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such provision and such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions of this Agreement or such Loan Document or affecting the
validity or enforceability of such provision in any other jurisdiction.

     SECTION 11.7.  Headings.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not
affect the meaning or interpretation of this Agreement or such other Loan
Document or any provisions hereof or thereof.

     SECTION 11.8.  Execution in Counterparts, Effectiveness, etc.  This
Agreement may be executed by the parties hereto in several counterparts, each
of which shall be executed by the Borrowers and the Agent and be deemed to be
an original and all of which shall constitute together but one and the same
agreement.  This Agreement shall become effective when counterparts hereof
executed on behalf of the Borrowers and each Lender (or notice thereof
satisfactory to the Agent) shall have been received by the Agent and notice
thereof shall have been given by the Agent to each Borrower and each Lender.

     SECTION 11.9.  Governing Law; Entire Agreement.  THIS AGREEMENT, THE
NOTES AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE
UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS.  This
Agreement, the Notes and the other Loan Documents constitute the entire
understanding among the parties hereto with respect to the subject matter
hereof and supersede any prior agreements, written or oral, with respect
thereto.

     SECTION 11.10.  Successors and Assigns.  This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that:

          (a)  the Borrowers may not assign or transfer their rights or
     obligations hereunder without the prior written consent of the Agent and
     all Lenders; and

          (b)  the rights of sale, assignment and transfer of the Lenders
     are subject to Section 11.11.

     SECTION 11.11.  Sale and Transfer of Loans and Notes; Participations in
Loans and Notes.  Each Lender may assign, or sell participations in, its Loans
and Commitments to one or more commercial banks in accordance with this
Section 11.11.

     SECTION 11.11.1.  Assignments.  Any Lender, with the written consents of
Simpson and the Agent (which consents shall not be unreasonably delayed or
withheld and which consent, in the case of Simpson, shall be deemed to have
been given in the absence of a written notice delivered by Simpson to the
Agent, on or before the seventh Business Day after receipt by Simpson of such
Lender's request for consent, stating, in reasonable detail, the reasons why
Simpson proposes to withhold such consent and which consent of Simpson shall
not be required, if a Default shall have occurred and be continuing) may at
any time assign and delegate to one or more financial institutions, (each
Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred
to as an "Assignee Lender"), all or any fraction of such Lender's total Loans
and Commitments (which assignment and delegation shall be of a constant, and
not a varying, percentage of all the assigning Lender's Loans and Commitments)
in a minimum aggregate amount of $10,000,000; provided, however, that any such
Assignee Lender will comply, if applicable, with the provisions contained in
the last sentence of Section 5.6 and further, provided, however, that, each
Borrower and the Agent shall be entitled to continue to deal solely and
directly with such Lender in connection with the interests so assigned and
delegated to an Assignee Lender until the Assignment Effective Date (the
"Assignment Effective Date").

The Assignment Effective Date shall be the date when all the following
conditions shall have been met:

          (i)  five Business Days shall have passed after written notice of
     such assignment and delegation, together with payment instructions,
     addresses and related information with respect to such Assignee Lender,
     shall have been given to Simpson and the Agent by such Lender and such
     Assignee Lender,

          (ii)  such Assignee Lender shall have executed and delivered to
     Simpson and the Agent a Lender Assignment Agreement, accepted by the
     Agent, and

          (iii)  the processing fees described below shall have been paid.

From and after the date that the Agent accepts such Lender Assignment
Agreement, (x) the Assignee Lender thereunder shall be deemed automatically to
have become a party hereto and to the extent that rights and obligations
hereunder have been assigned and delegated to such Assignee Lender in
connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents, and
(y) the assignor Lender, to the extent that rights and obligations hereunder
have been assigned and delegated by it in connection with such Lender
Assignment Agreement, shall be released from its obligations hereunder and
under the other Loan Documents.  Within five Business Days after receipt of
notice that the Agent has received an executed Lender Assignment Agreement,
the Borrowers shall execute and deliver to the Agent (for delivery to the
relevant Assignee Lender) new Notes evidencing such Assignee Lender's assigned
Loans and Commitments and, if the assignor Lender has retained Loans and
Commitments hereunder, replacement Notes in the principal amount of the Loans
and Commitments retained by the assignor Lender hereunder (such Notes to be in
exchange for, but not in payment of, those Notes then held by such assignor
Lender).  Each such Note shall be dated the date of the predecessor Notes. 
The assignor Lender shall mark the predecessor Notes "exchanged" and deliver
them to such Borrower.  Accrued interest on that part of the predecessor Notes
evidenced by the new Notes, and accrued fees, shall be paid as provided in the
Lender Assignment Agreement.  Accrued interest on that part of the predecessor
Notes evidenced by the replacement Notes shall be paid to the assignor Lender. 
Accrued interest and accrued fees shall be paid at the same time or times
provided in the predecessor Notes and in this Agreement.  Such assignor Lender
or such Assignee Lender must also pay a processing fee to the Agent upon
delivery of any Lender Assignment Agreement in the amount of $3500.  Any
attempted assignment and delegation not made in accordance with this
Section 11.11.1 shall be null and void.  Nothing herein shall prohibit any
Lender from pledging or assigning any Note or any of its rights under this
Agreement to any Federal Reserve Bank in accordance with applicable law.

     SECTION 11.11.2.  Participations.  Any Lender may at any time sell to
one or more commercial banks (each of such commercial banks being herein
called a "Participant") participating interests (or a sub-participating
interest, in the case of a Lender's participating interest in a Letter of
Credit) in any of the Loans, Commitments, or other interests of such Lender
hereunder; provided, however, that

          (a)  no participation or sub-participation contemplated in this
     Section 11.11 shall relieve such Lender from its Commitments or its
     other obligations hereunder or under any other Loan Document,

          (b)  such Lender shall remain solely responsible for the
     performance of its Commitments and such other obligations,

          (c)  each Borrower and the Agent shall continue to deal solely and
     directly with such Lender in connection with such Lender's rights and
     obligations under this Agreement and each of the other Loan Documents,

          (d)  no Participant, unless such Participant is an Affiliate of
     such Lender, or is itself a Lender, shall be entitled to require such
     Lender to take or refrain from taking any action hereunder or under any
     other Loan Document, except that such Lender may agree with any
     Participant that such Lender will not, without such Participant's
     consent, take any actions of the type described in clause (b) or (c) of
     Section 11.1, and

          (e)  no Borrower shall be required to pay any amount under
     Section 5.6 that is greater than the amount which it would have been
     required to pay had no participating interest been sold.

The Borrower acknowledges and agrees that each Participant, for purposes of
Sections 5.3, 5.4, 5.5, 5.6, 5.8, 5.9, 11.3 and 11.4 shall be considered a
Lender.

     SECTION 11.11.3.  Information.  Each Lender is hereby authorized to
disclose all information concerning the Borrowers to assignees, participants,
potential assignees and potential participants.

     SECTION 11.11.4.  Confidentiality.  The Lenders shall hold all non-
public information (which has been identified as such by a Borrower) obtained
pursuant to the requirements of this Agreement in accordance with their
customary procedures for handling confidential information of this nature and
in accordance with safe and sound banking practices and in any event may make
disclosure to any of their examiners, Affiliates, outside auditors, counsel
and other professional advisors in connection with this Agreement or as
reasonably required by any bona fide transferee, participant or assignee or as
required or requested by any governmental agency or representative thereof or
pursuant to legal process; provided however, that 

          (a)  unless specifically prohibited by applicable law or court
     order, each Lender shall notify the Borrowers of any request by any
     governmental agency or representative thereof (other than any such
     request in connection with an examination of the financial condition of
     such Lender by such governmental agency) for disclosure of any such non-
     public information prior to disclosure of such information;

          (b)  prior to any such disclosure pursuant to this Section
     11.11.4, each Lender shall require any such bona fide transferee,
     participant and assignee receiving a disclosure of non-public
     information to agree in writing

               (i)  to be bound by this Section 11.11.4; and

               (ii)  to require such Person to require any other Person to
          whom such Person discloses such non-public information to be
          similarly bound by this Section 11.11.4; and

          (c)  except as may be required by an order of a court of competent
     jurisdiction and to the extent set forth therein, no Lender shall be
     obligated or required to return any materials furnished by the Borrowers
     or any Subsidiary.

     SECTION 11.12.  Additional Borrowers.

          Each Subsidiary of Simpson may become a Borrower hereunder upon
     becoming such a Subsidiary.  Simpson shall deliver an Additional
     Borrower Certificate executed by any such Subsidiary and Simpson
     together with such supporting resolutions, incumbency certificates and
     opinions of counsel as the Agent may reasonably request.  Such
     Subsidiary shall thereupon become a party hereto and a Borrower
     hereunder and shall be (i) entitled to all rights and benefits of a
     Borrower hereunder and under each instrument executed pursuant hereto
     and (ii) subject to all obligations of a Borrower hereunder and
     thereunder.

     SECTION 11.13.  Joint and Several Liability.

          (a)  The Obligations of the Borrowers are joint and several;
     except that each Subsidiary Borrower which is not a U.S. Subsidiary of
     Simpson shall be liable only for Loans made to it and with respect to
     Letters of Credit issued for its account.

          (b)  Each Borrower acknowledges and agrees that it is the intent
     of the parties that each Borrower be primarily liable for the
     Obligations as a joint and several obligor (except as specifically set
     forth in this Section 11.13).  It is the intention of the parties that
     with respect to liability of any Borrower hereunder arising solely by
     reason of its being jointly and severally liable for Borrowings and
     Loans taken by other Borrowers, the obligations of such Borrower shall
     be absolute, unconditional and irrevocable irrespective of:

               (i)  any lack of validity, legality or enforceability of
          this Agreement or any Note as to any other Borrower;

               (ii)  the failure of any Lender or any holder of any Note

                    (A)  to enforce any right or remedy against any
               Borrower or any other Person (including any guarantor) under
               the provisions of this Agreement, the Note, or otherwise, or

                    (B)  to exercise any right or remedy against any
               guarantor of, or collateral securing, any Obligations;

               (iii)  any change in the time, manner or place of payment
          of, or in any other term of, all or any of the Obligations, or any
          other extension, compromise or renewal of any Obligations;

               (iv)  any reduction, limitation, impairment or termination
          of any Obligations with respect to any other Borrower for any
          reason, including any claim of waiver, release, surrender,
          alteration or compromise, and shall not be subject to (and each
          Borrower hereby waives any right to or claim of) any defense or
          setoff, counterclaim, recoupment or termination whatsoever by
          reason of the invalidity, illegality, nongenuineness,
          irregularity, compromise, unenforceability of, or any other event
          or occurrence affecting, any Obligations with respect to any other
          Borrower;

               (v)  any addition, exchange, release, surrender or
          nonperfection of any collateral, or any amendment to or waiver or
          release or addition of, or consent to departure from, any
          guaranty, held by any Lender or any holder of the Note securing
          any of the Obligations; or

               (vi)  any other circumstance which might otherwise
          constitute a defense available to, or a legal or equitable
          discharge of, any other Borrower, any surety or any guarantor.

          Each Borrower agrees that its joint and several liability
     hereunder shall continue to be effective or be reinstated, as the case
     may be, if at any time any payment (in whole or in part) of any of the
     Obligations is rescinded or must be restored by any Lender or any holder
     of any Note, upon the insolvency, bankruptcy or reorganization of any
     Borrower as though such payment had not been made.

          Each Borrower hereby expressly waives:  (a) notice of the Lenders'
     acceptance of this Agreement; (b) notice of the existence or creation or
     non payment of all or any of the Obligations; (e) presentment, demand,
     notice of dishonor, protest, and all other notices whatsoever other than
     notices expressly provided for in this Agreement; and (d) all diligence
     in collection or protection of or realization upon the Obligations or
     any thereof, any obligation hereunder, or any security for or guaranty
     of any of the foregoing.

          No delay on any of the Lenders' part in the exercise of any right
     or remedy shall operate as a waiver thereof, and no single or partial
     exercise by any of the Lenders of any right or remedy shall preclude
     other or further exercise thereof or the exercise of any other right or
     remedy.  No action of any of the Lenders permitted hereunder shall in
     any way affect or impair any such Lenders' rights or any Borrower's
     obligations under this Agreement.

          Notwithstanding the foregoing, each Borrower other than Simpson
     shall be liable for the Obligations for the maximum amount of such
     liability that can be hereby incurred without rendering this Agreement,
     any Note or any other Loan Document voidable under applicable law,
     including applicable law relating to fraudulent conveyance or fraudulent
     transfer, and not for any greater amount.

          Each Borrower hereby represents and warrants to each of the
     Lenders that it now has and will continue to have independent means of
     obtaining information concerning the Borrowers' affairs, financial
     condition and business.  Lenders shall not have any duty or
     responsibility to provide any Borrower with any credit or other
     information concerning the Borrowers' affairs, financial condition or
     business which may come into the Lenders' possession.

     SECTION 11.14. Judgment Currency. Each Borrower, the Agent and each Lender
hereby agree that if, in the event that a judgment is given in relation to any
sum due to the Agent or any Lender hereunder, such judgment is given in a
currency (the "Judgment Currency") other than that in which such sum was
originally denominated (the "Original Currency"), the Borrower jointly and
severally agree to indemnify the Agent or such Lender, as the case may be, to
the extent that the amount of the Original Currency which could have been
purchased by the Agent in accordance with normal banking procedures on the
Business Day following receipt of such sum is less than the sum which could
have been so purchased by the Agent had such purchase been made on the day on
which such judgment was given or, if such day is not a Business Day, on the
Business Day immediately preceding the giving of such judgment.  The
agreements in this Section shall survive payment of all other Obligations.

     SECTION 11.15.  Other Transactions.  Nothing contained herein shall
preclude the Agent or any other Lender from engaging in any transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with any Borrower or any of its Affiliates in which any Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

     SECTION 11.16.  Consent to Jurisdiction.   THE BORROWERS HEREBY
ABSOLUTELY AND IRREVOCABLY CONSENTS AND SUBMITS TO THE JURISDICTION OF THE
COURTS OF THE STATE OF ILLINOIS OR THE UNITED STATES OF AMERICA FOR THE
NORTHERN DISTRICT OF ILLINOIS IN CONNECTION WITH ANY ACTIONS OR PROCEEDINGS
BROUGHT AGAINST ANY OF THE BORROWERS BY THE AGENT OR THE LENDER ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE NOTES OR THE BANKING RELATIONSHIP GIVING
RISE TO THIS AGREEMENT, AND HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN
RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY
SUCH COURT.  THE BORROWERS HEREBY WAIVE AND AGREE NOT TO ASSERT IN SUCH ACTION
OR PROCEEDING, IN EACH CASE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY CLAIM THAT (a) ANY BORROWER IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF ANY SUCH COURT; (b) ANY BORROWER IS IMMUNE FROM ANY LEGAL
PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION, EXECUTION OR OTHERWISE) WITH RESPECT TO IT OR
ITS PROPERTY; (c) ANY SUCH SUIT, ACTION OR PROCEEDING IS BROUGHT IN AN
INCONVENIENT FORUM; OR (d) THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING IS
IMPROPER.  IN ANY SUCH ACTION OR PROCEEDING, ANY BORROWER HEREBY ABSOLUTELY
AND IRREVOCABLY WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT, DECLARATION
OR OTHER PROCESS AND HEREBY ABSOLUTELY AND IRREVOCABLY AGREES THAT THE SERVICE
THEREOF MAY BE MADE BY CERTIFIED OR REGISTERED AIRMAIL, POSTAGE PREPAID,
DIRECTED TO SUCH BORROWER AT THE ADDRESS SHOWN ON THE SIGNATURE PAGE HEREOF
(OR AT SUCH OTHER ADDRESS AS SUCH BORROWER SHALL LAST SPECIFY TO THE AGENT IN
WRITING).  NOTHING CONTAINED IN THIS AGREEMENT OR THE NOTES SHALL AFFECT ANY
RIGHT THAT THE AGENT, THE LENDERS OR ANY BORROWER MAY OTHERWISE HAVE TO BRING
ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTES OR THE
BANKING RELATIONSHIP GIVING RISE TO THIS AGREEMENT AGAINST ANY BORROWER, THE
AGENT OR THE LENDERS, AS THE CASE MAY BE, OR THEIR PROPERTIES IN THE COURTS OF
ANY OTHER JURISDICTION, OR ANY RIGHT THAT THE LENDERS, THE AGENT OR ANY
BORROWER MAY HAVE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

     SECTION 11.17.  Waiver of Jury Trial.  THE AGENT, THE LENDERS AND THE
BORROWERS HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHTS IT
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE LENDERS OR THE BORROWERS.  THE
BORROWERS ACKNOWLEDGE AND AGREE THAT IT HAS RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE AGENT AND THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.


     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized as of the day
and year first above written.
