     2.   LOANS AND LETTERS OF CREDIT.
          --------------------------- 

          2.1  Revolving Loans.  The Lender shall, subject to the terms and
               ---------------                                             
conditions set forth in this Agreement, and upon any Borrower's request from
time to time, make revolving loans (the "Revolving Loans") to such Borrower up
to the limits of the Availability.  The Lender, in its discretion, may elect to
exceed the limits of the Availability on one or more occasions, but if it does

                                       18
<PAGE>
 
so, the Lender shall not be deemed thereby to have changed the limits of the
Availability or to be obligated to exceed the limits of the Availability on any
other occasion.  If the unpaid balance of the Revolving Loans exceeds the
Availability (with Availability for this purpose determined as if the amount of
the Revolving Loans were zero), then the Lender may refuse to make or otherwise
restrict Revolving Loans on such terms as the Lender determines until such
excess has been eliminated.  Each Borrower may request Revolving Loans either
orally or in writing, provided, however, that each such request with respect to
Reference Rate Loans shall be made no later than 1:00 p.m. (Los Angeles,
California time).  Each oral request for a Revolving Loan shall be conclusively
presumed to be made by a person authorized by the Borrower to do so and the
crediting of a Revolving Loan to the Borrower's deposit account, or transmittal
to such Person as the Borrower shall direct, shall conclusively establish the
obligation of the Borrower to repay such Revolving Loan.  The Lender will charge
all Revolving Loans and other Obligations to a loan account of the Borrower
maintained with the Lender.  All fees, commissions, costs, expenses, and other
charges due from the Borrower pursuant to the Loan Documents, and all payments
made and out-of-pocket expenses incurred by Lender and authorized to be charged
to the Borrower pursuant to the Loan Documents, will be charged as Revolving
Loans to the Borrower's loan account as of the date due from the Borrower or the
date paid or incurred by the Lender, as the case may be.

          2.2  Availability Determination.  Availability of each Borrower will
               --------------------------                                     
be determined by the Lender in accordance with the terms of this Agreement, each
day on the basis of such relevant information as the Lender deems appropriate to
consider, including the collateral summary reports and such other information
regarding the Accounts and the Inventory as the Lender shall obtain from such
Borrower.

          2.3  Letters of Credit.  The Lender will, subject to the terms and
               -----------------                                            
conditions of this Agreement and the "Letter of Credit Agreement" as hereinafter
defined, and upon any Borrower's request from time to time, cause merchandise
letters of credit (the "Merchandise L/C's") or standby letters of credit (the
"Standby L/C's") to be issued for the Borrower's account (the Merchandise L/C's
and the Standby L/C's being referred to collectively as the "Letters of
                                                             ----------
Credit").  The Lender will not cause to be opened any Letter of Credit if:  (a)
------
the maximum face amount of the requested Letter of Credit, plus the aggregate
undrawn face amount of all outstanding Letters of Credit under this Agreement
and the other LSB-Related Loan Agreements, would exceed Eleven Million and
No/100 Dollars ($11,000,000); or (b) the maximum face amount of the requested
Letter of Credit, and all commissions, fees, and charges due from Borrower to
Lender in connection with the opening thereof, would cause the Availability to
be exceeded at such time.  In addition, with respect to any Merchandise L/C, the
requested term of such Letter of Credit may not exceed 180 days, and no
Merchandise L/C may by its terms be scheduled to be outstanding on the
Termination Date.  Standby L/C's may have terms that extend beyond the
Termination Date but, upon termination of this Agreement, all Letters of Credit
must be either terminated with the consent of the beneficiary thereof, replaced
with a letter of credit provided by a financial institution acceptable to
Lender, collateralized by cash or cash equivalent, or otherwise satisfied in a
manner acceptable to Lender.  The Letters of Credit shall be governed by a
Letter of Credit Financing Agreement -  Supplement to Amended and Restated Loan
and Security Agreement between the Lender and the Borrower ("Letter of Credit
                                                             ----------------
Agreement"), in the form attached hereto as Exhibit "O" and made a part hereof,
---------                                   ----------                        
in addition to the terms and conditions hereof.  All payments made and expenses
incurred by the 

                                       19
<PAGE>
 
Lender pursuant to or in connection with the Letters of Credit and the Letter of
Credit Agreement will be charged to the Borrower's loan account as Revolving
Loans.

          2.4  Swap Transactions.  EDC may request and the Lender may, in its
               -----------------                                             
sole and absolute discretion, arrange for EDC to obtain Swap Transactions from
the Bank in amounts to be agreed to between EDC and Bank.  EDC agrees to
indemnify and hold the Lender harmless from any and all obligations now or
hereafter owing by the Lender to the Bank arising from or related to such Swap
Transactions pursuant to the indemnity referred to in clause (c) below.  EDC
agrees to pay the Bank all amounts owing to the Bank pursuant to the Swap
Transactions.  In the event EDC shall not have paid to the Bank such amounts,
the Lender shall pay the Bank and such amounts when paid by the Lender shall
constitute a Revolving Loan of EDC which shall be deemed to have been requested
by EDC.  EDC acknowledges and agrees that the obtaining of Swap Transactions
from the Bank (a) is in the sole and absolute discretion of the Bank, (b) is
subject to all rules and regulations of the Bank, and (c) is due to the Bank
relying on the indemnity of the Lender to the Bank with respect to the
obligations of EDC to the Bank in connection with the Swap Transactions.  EDC
agrees to pay Lender a Swap Transaction Fee equal to one percent (1%) per annum
times the amount of all outstanding Swap Transactions.

     3.   INTEREST AND OTHER CHARGES
          --------------------------

          3.1  Interest.
               -------- 

          (a)  Interest Rates. All amounts charged as Revolving Loans shall bear
               --------------
interest on the unpaid principal amount thereof from the date made until paid in
full in cash at the Applicable Interest Rate as described in Sections 3.1(a)(i)
                                                             ------------------
and (ii) but not to exceed the maximum rate permitted by applicable law. Subject
--------
to the provisions of Section 3.2, any of the Revolving Loans may be converted
                     -----------
into, or continued as, Reference Rate Loans or Eurodollar Rate Loans in the
manner provided in Section 3.2. If at any time Revolving Loans are outstanding
                   ------------
with respect to which notice has not been delivered to Lender in accordance with
the terms of this Agreement specifying the basis for determining the interest
rate applicable thereto, then those Revolving Loans shall be Reference Rate
Loans and shall bear interest at a rate determined by reference to the Reference
Rate until notice to the contrary has been given to the Lender and such notice
has become effective. Except as other wise provided herein, the amounts charged
as Revolving Loans shall bear interest at the following rates (the "Applicable
Interest Rate"):

          (i)  For all amounts charged as Revolving Loans other than Eurodollar
     Rate Loans, including all Revolving Loans which are Reference Rate Loans,
     then at a fluctuating per annum rate equal to one and one-half percent
     (1.50%) per annum (the "Reference Rate Margin") plus the Reference Rate;
     and

          (ii) If the Revolving Loans are Eurodollar Rate Loans, then at a per
     annum rate equal to three and seven-eighths percent (3.875%) per annum (the
     "Eurodollar Margin") plus the Eurodollar Rate determined for the applicable
     Interest Period.

     Notwithstanding the foregoing, if, during any month, the sum of the average
     "Availability" (as defined in each of the LSB-Related Loan Agreements) of
     the LSB Consolidated

                                       20
<PAGE>
 
     Borrowing Group under all of the LSB-Related Loan Agreements is less than
     $6,300,000, then, during the following month, the Reference Rate Margin
     will be increased to two percent (2%) and the Eurodollar Margin will be
     increased to four and three-eighths percent (4.375%).

     In addition, if the LSB Adjusted Tangible Net Worth equals or exceeds
     $72,500,000, as reflected on LSB's most current quarterly Financial
     Statements, provided no Event of Default has occurred and is continuing,
     then for so long as the LSB Adjusted Tangible Net Worth is at least
     $72,500,000, the Reference Rate Margin will be reduced to one percent (1%)
     and the Eurodollar Margin will be reduced to three and three-eighths
     percent (3.375%), and the reduction will be effective as of the first day
     of the month following receipt by Lender of the applicable quarterly
     Financial Statements.

     Finally, if the LSB Adjusted Tangible Net Worth equals or exceeds
     $84,000,000, as reflected on LSB's most current quarterly Financial
     Statements, provided no Event of Default has occurred and is continuing,
     then for so long as the LSB Adjusted Tangible Net Worth is at least
     $84,000,000, the Reference Rate Margin will be reduced to one-half of one
     percent (.50%) and the Eurodollar Margin will be reduced to two and seven-
     eighths percent (2.875%), and the reduction will be effective as of the
     first day of the month following receipt by Lender of the applicable
     quarterly Financial Statements.

     Each change in the Reference Rate shall be reflected in the interest rate
described in (i) above as of the effective date of such change.  All interest
charges shall be computed on the basis of a year of three hundred sixty (360)
days and actual days elapsed.  Except as otherwise provided herein, (1) interest
accrued on each Eurodollar Rate Loan shall be payable in arrears on each
Eurodollar Interest Payment Date applicable to such Eurodollar Rate Loan, and
(2) interest accrued on the Reference Rate Loans will be payable in arrears on
the first day of each month hereafter.

          (b)  Default Rate.  If any Event of Default occurs, then, while any
               ------------                                                  
such Event of Default is continuing, all Loans shall bear interest at an
increased rate of interest equal to the Applicable Interest Rate thereto plus
                                                                         ----
two percent (2.0%) per annum, and the Letter of Credit Fee and the Swap
Transaction Fee shall each be increased to three percent (3%) per annum.

          3.2  Eurodollar Borrowings: Conversion or Continuation.
               ------------------------------------------------- 

          (a)  Subject to the provisions of Section 3.3, each Borrower shall
                                            -----------
have the option: (i) to request the Lender to make a Revolving Loan as a
Eurodollar Rate Loan; (ii) to convert all or any part of the outstanding
Revolving Loans from Reference Rate Loans to Eurodollar Rate Loans, (iii) to
convert all or any part of the outstanding Revolving Loans from Eurodollar Rate
Loans to Reference Rate Loans on the expiration of the Interest Period
applicable thereto; (iv) upon the expiration of any Interest Period applicable
to any outstanding Eurodollar Rate Loan, to continue all or any portion of such
Eurodollar Rate Loan as a Eurodollar Rate Loan; provided, however, that no
                                                --------  -------
outstanding Loans may be converted into or continued as, Eurodollar Rate Loans
when any Event or Event of Default has occurred and is continuing.

                                       21
<PAGE>
 
          (b)  Whenever the Borrower elects to borrow, convert into or continue
Eurodollar Rate Loans under this Section 3.2, the Borrower shall notify the
                                 -----------  
Lender in writing or telephonically no later than 11:00 a.m. (Los Angeles,
California time) two (2) Business Days in advance of the requested
borrowing/conversion/continuation date. The Borrower shall specify (1) the
borrowing/conversion/continuation date (which shall be a Business Day), (2) the
amount and type of the Revolving Loans to be borrowed/converted/continued, and
(3) the nature of the requested borrowing/ conversion/continuation. In the event
that the Borrower should fail to timely notify the Lender to continue to convert
any existing Eurodollar Rate Loan, such Loan shall, on the last day of the
Interest Period with respect to such Revolving Loan, convert to a Reference Rate
Loan.

          (c)  The officer of the Borrower authorized by the Borrower to request
Revolving Loans on behalf of the Borrower shall also be authorized to request a
conversion/continuation on behalf of the Borrower.  The Lender shall be entitled
to rely on such officer's authority until the Lender is notified to the contrary
in writing.  The Lender shall have no duty to verify the  authenticity of the
signature appearing on any written notification or request and, with respect to
an oral notification or request, the Lender shall have no duty to verify the
identity of any individual representing himself as one of the officers
authorized to make such notification or request on behalf of the Borrower.  The
Lender shall incur no liability to the Borrower in acting upon any telephonic
notice or request referred to in this Section 3.2, which the Lender believes in
                                      -----------                              
good faith to have been given by an officer authorized to do so on behalf of the
Borrower, or for otherwise acting in good faith under this Section 3.2 and, upon
                                                           -----------          
lending/conversion/continuation by the Lender in accordance with this Agreement
pursuant to any such telephonic notice, the Borrower shall have effected the
borrowing/conversion/continuation of the applicable Loans hereunder.

          (d)  Any written or telephonic notice of conversion to, or borrowing
or continuation of, Revolving Loans made pursuant to this Section 3.2 shall be
                                                          -----------
irrevocable and the Borrower shall be bound to borrow, convert or continue in
accordance therewith.

          3.3  Special Provisions Governing Eurodollar Rate Loans.
               --------------------------------------------------  
Notwithstanding any other provisions to the contrary contained in this
Agreement, the following provisions shall govern with respect to Eurodollar Rate
Loans as to the matters covered:

          (a)  Amount of Eurodollar Rate Loans.  Each election of, continuation
               -------------------------------                                 
of, or conversion to a Eurodollar Rate Loan, shall be in a minimum amount of
Five Million Dollars ($5,000,000) and in integral multiples of One Million
Dollars ($1,000,000) in excess of that amount.

          (b)  Determination of Interest Period.  The Interest Period for each
               --------------------------------                               
Eurodollar Rate Loan shall be for a three (3) month period.  The determination
of Interest Periods shall be subject to the following provisions:

               (i)  In the case of immediately successive Interest Periods, each
     successive Interest Period shall commence on the day on which the next
     preceding Interest Period expires.

               (ii) If any Interest Period would otherwise expire on a day which
     is not a Business Day, the Interest Period shall be extended to expire on
     the next succeeding Business 

                                       22
<PAGE>
 
     Day; provided, however, that if the next succeeding Business Day occurs in
          --------  -------
     the following calendar month, then such Interest Period shall expire on the
     immediately preceding Business Day.

               (iii)   The Borrower may not select an Interest Period for any
     Eurodollar Rate Loan, which Interest Period expires later than the
     Termination Date.

               (iv)    There shall be not more than two (2) Interest Periods in
     effect at any one time, and no more than two (2) Interest Periods may begin
     during any calendar month.

               (v)     If an Interest Period starts on a date for which no
     numerical correspondent exists in the month in which such Interest Period
     ends, such Interest Period will end on the last Business Day of such month.

          (c)  Determination of Interest Rate.  As soon as practicable after
               ------------------------------                               
11:00 a.m. (Los Angeles, California time) on the Eurodollar Interest Rate
Determination Date, the Lender shall determine (which determination shall,
absent manifest error, be presumptively correct) the Interest Rate for the
Eurodollar Rate Loans for which an Interest Rate is then being determined and
shall promptly give notice thereof (in writing or by telephone confirmed in
writing) to the Borrower.

          (d)  Substituted Rate of Borrowing.  In the event that on any
               -----------------------------                           
Eurodollar Interest Rate Determination Date the Lender shall have determined
(which determination shall, absent manifest error, be presumptively correct and
binding upon all parties) that:

               (i)     by reason of any changes arising after the date of this
     Agreement affecting the interbank Eurodollar market or affecting the
     position of Bank or Lender in such market, adequate and fair means do not
     exist for ascertaining the applicable interest rates by reference to which
     the Eurodollar Rate then being determined is to be fixed; or

               (ii)    by reason of (1) any change after the date of this
     Agreement in any applicable law or governmental rule, regulation or order
     (or any interpretation thereof and including the introduction of any new
     law or governmental rule, regulation or order) or (2) any other
     circumstances affecting Bank or Lender or the interbank Eurodollar market
     or the position of Bank or Lender in such market (such as, for example, but
     not limited to, official reserve requirements required by Regulation D of
     the Board of Governors of the Federal Reserve System to the extent not
     given effect in the Eurodollar Rate), the Eurodollar Rate shall not
     represent the effective pricing to Lender for Dollar deposits of comparable
     amounts for the relevant period;

then, and in any such event, the right of the Borrower to request application of
the Eurodollar Rate to some or all of the Loans shall be suspended until the
Lender shall notify the Borrower that the circumstances causing such suspension
no longer exist, and such Loans shall be Reference Rate Loans.

          (e)  Illegality.  In the event that on any date Lender shall have
               ----------                                                  
reasonably determined (which determination shall, absent manifest error, be
final and conclusive and binding 

                                       23
<PAGE>
 
upon all parties) that the making of, conversion into, or the continuation of,
Lender's Eurodollar Rate Loans has become unlawful as the result of compliance
by Lender or Bank in good faith with any law, governmental rule, regulation or
order (whether or not having the force of law and whether or not failure to
comply therewith would be unlawful), then, and in any such event, Lender shall
promptly give notice (by telephone confirmed in writing) to the Borrower of such
determination. In such case and except as provided in Section 3.3(f), the
                                                      -------------- 
obligation of Lender to make or maintain any Eurodollar Rate Loans during any
such period shall be terminated at the earlier of the termination of the
Interest Period then in effect or when required by law, and the Borrower shall,
no later than the earlier of the termination of the Interest Period in effect at
the time any such determination pursuant to this Section 3.3(e) is made, or when
                                                 --------------
required by law, repay the Eurodollar Rate Loans, together with all interest
accrued thereon.

          (f)  Options of the Borrower. In lieu of prepaying the Eurodollar Rate
               -----------------------
Loans as required by Section 3.3(e), the Borrower may exercise either of the
following options:

               (i)  Upon written notice to the Lender, the Borrower may release
     Lender from its obligations to make or maintain Loans as Eurodollar Rate
     Loans and in such event, the Borrower shall, at the end of the then current
     Interest Period (or at such earlier time as prepayment is otherwise
     required), convert all of the Eurodollar Rate Loans into Reference Rate
     Loans in the manner contemplated by Section 3.2, but without satisfying the
                                         -----------
     advance notice requirements therein; or

               (ii) The Borrower may, by giving notice (by telephone confirmed
     immediately by telecopy) to Lender require Lender to continue to maintain
     its outstanding Reference Rate Loans as Reference Rate Loans, but without
     satisfying the advance notice requirements set forth in such Section 3.2.
                                                                  ----------- 

          (g)  Compensation.  In addition to such amounts as are required to be
               ------------                                                    
paid by the Borrower pursuant to the other Sections of this Article 3, the
Borrower agrees to compensate the Lender for all expenses and liabilities,
including, without limitation, any loss or expense incurred by Lender by reason
of the liquidation or reemployment of deposits or other funds acquired by Lender
to fund or maintain the Lender's Eurodollar Rate Loans to the Borrower, which
Lender sustains (i) if due to the fault of the Borrower a funding of any
Eurodollar Rate Loans does not occur on a date specified therefor by Borrower in
a telephonic or written request for borrowing or conversion/continuation, or a
successive Interest Period does not commence after notice therefor is given
pursuant to Section 3.2, (ii) if any voluntary or mandatory prepayment of any
            -----------                                                      
Eurodollar Rate Loans occurs for any reason on a date which is not the last
scheduled day of an Interest Period, or (iii) as a consequence of any other
                                     --                                    
failure by the Borrower to repay Eurodollar Rate Loans when required by the
terms of this Agreement.

          (h)  Quotation of Eurodollar Rate.  Anything herein to the contrary
               ----------------------------                                  
notwithstanding, if on any Eurodollar Interest Rate Determination Date no
Eurodollar Rate is available by reason of the failure of Bank to be offered
quotations in accordance with the definition of "Eurodollar Base Rate," the
Lender shall give the Borrower prompt notice thereof and (i) any Eurodollar Rate
Loan requested to be made at the Eurodollar Rate to be determined on any
Eurodollar Interest Rate Determination Date shall be made as a Reference Rate
Loan, and (ii) any 

                                       24
<PAGE>
 
notice given by the Borrower to convert any Loans into or to continue any Loans
as Eurodollar Rate Loans at the Eurodollar Rate to be determined on any such
Eurodollar Interest Rate Determination Date shall be ineffective.

          (i)  Eurodollar Rate Taxes.  The Borrower agrees that it will pay,
               ---------------------                                        
prior to the date on which penalties attach thereto, all present and future
income, stamp and other taxes, levies, or costs and charges whatsoever imposed,
assessed, levied or collected on or from the Lender on or in respect of the
Borrower's Loans from the Lender solely as a result of the interest rate being
determined by reference to the Eurodollar Rate and/or the provisions of this
Agreement relating to the Eurodollar Rate and/or the recording, registration,
notarization or other formalization of any of the foregoing and/or any payments
of principal, interest or other amounts made on or in respect of the Loans from
the Lender when the interest rate is determined by reference to the Eurodollar
Rate (all such taxes, levies, cost and charges being herein collectively called
"Eurodollar Rate Taxes"); provided, however, that Eurodollar Rate Taxes shall
 ---------------------    --------  -------                                  
not include taxes imposed on or measured by the overall net income of the Lender
by the United States of America or any political subdivision or taxing authority
thereof or therein, or taxes on or measured by the overall net income by any
foreign branch or subsidiary of the Lender by any foreign country or subdivision
thereof in which that branch or subsidiary is doing business.  Promptly after
the date on which payment of any such Eurodollar Rate Tax is due pursuant to
applicable law, the Borrower will, at the request of the Lender, furnish to the
Lender evidence, in form and substance satisfactory to the Lender, that the
Borrower has met its obligation under this Section 3.3(i), an addition, the
                                           --------------                  
Borrower will indemnify the Lender against, and reimburse Lender on demand for,
any Eurodollar Rate Taxes for which the Lender is or may be liable by reason of
the making or maintenance of any Eurodollar Rate Loans hereunder, as determined
by the Lender in its discretion exercised in good faith and pursuant to
standards of commercial reasonableness.  The Lender shall provide Borrower with
appropriate receipts for any payments or reimbursements made by Borrower
pursuant to this Section 3.3(i).
                 -------------- 

          (j)  Booking of Eurodollar Rate Loans.  The Lender may make, carry or
               --------------------------------                                
transfer Eurodollar Rate Loans at, to, or for the account of, any of its branch
offices or the office of any of its Affiliates.

          (k)  Increased Costs. If, due to either (i) the introduction of or any
               ---------------
change (other than any change by way of imposition or increase of reserve
requirements included in the Eurodollar Reserve Percentage) in or in the
interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other Public Authority (whether or
not having the force of law), there shall be any increase in the cost to the
Lender of agreeing to make or making, funding or maintaining Eurodollar Rate
Loans, then the Borrower agrees that it shall, from time to time, upon demand by
the Lender in writing to the Borrower, within sixty (60) days from the date of
such increased cost, pay to the Lender additional amounts sufficient to
compensate the Lender for such increased cost relating to the outstanding
Eurodollar Rate Loans made to the Borrower. A certificate as to the amount of
such increased cost and the method of determination thereof, submitted to the
Borrower by the Lender, shall be rebuttably presumptive evidence of the
correctness of such amount. Notwithstanding the above, the Lender shall promptly
advise Borrower of any increased costs covered by this paragraph (k) of which
Lender is aware that have been made or which are proposed to be made which may
require the Borrower to be required to pay the increased cost 

                                       25

under this paragraph (k) prior to or at the time that Borrower requests
additional Eurodollar Rate Loans.

          3.4  Maximum Interest Rate.
               --------------------- 

          (a)  Notwithstanding the foregoing provisions of Sections 3.1 through
                                                           --------------------
3.3 regarding the rates of interest applicable to the Loans, if at any time the
---                                                                            
amount of such interest computed on the basis of the Applicable Interest Rate
would exceed the amount of such interest computed upon the basis of the maximum
rate of interest permitted by applicable state or federal law in effect from
time to time hereafter, after taking into account, to the extent required by
applicable law, any and all fees, payments, charges and calculations provided
for in this Agreement or in any other agreement between Borrower and Lender (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
 ------------------                                                      
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Reference Rate or the Eurodollar Rate shall not reduce such interest
thereafter payable hereunder below the amount computed on the basis of the
Maximum Legal Rate until the aggregate amount of such interest accrued and
payable under this Agreement equals the total amount of interest which would
have accrued if such interest had been at all times computed solely on the basis
of the Applicable Interest Rate.

          (b)  No agreements, conditions, provisions or stipulations contained
in this Agreement or any other instrument, document or agreement between the
Borrower and the Lender or default of the Borrower, or the exercise by the
Lender of the right to accelerate the payment of the maturity of principal and
interest, or to exercise any option whatsoever contained in this Agreement or
any other agreement between the Borrower and the Lender, or the arising of any
contingency whatsoever, shall entitle the Lender to collect, in any event,
interest exceeding the Maximum Legal Rate and in no event shall the Borrower be
obligated to pay interest exceeding such Maximum Legal Rate and all agreements,
conditions or stipulations, if any, which may in any event or contingency
whatsoever operate to bind, obligate or compel the Borrower to pay a rate of
interest exceeding the Maximum Legal Rate, shall be without binding force or
effect, at law or in equity, to the extent only of the excess of interest over
such Maximum Legal Rate. In the event any interest is charged in excess of the
Maximum Legal Rate ("Excess"), the Borrower acknowledges and stipulates that any
                     ------
such charge shall be the result of an accidental and bona fide error, and such
                                                     ---- ----
Excess shall be, first, applied to reduce the principal then unpaid hereunder;
second, applied to reduce the Obligations; and third, returned to the Borrower,
it being the intention of the parties hereto not to enter at any time into a
usurious or otherwise illegal relationship. The Borrower recognizes that, with
fluctuations in the Applicable Interest Rate and the Maximum Legal Rate, such an
unintentional result could inadvertently occur. By the execution of this
Agreement, the Borrower covenants that (i) the credit or return of any Excess
shall constitute the acceptance by the Borrower of such Excess, and (ii) the
Borrower shall not seek or pursue any other remedy, legal or equitable, against
Lender, based in whole or in part upon the charging or receiving of any interest
in excess of the maximum authorized by applicable law. For the purpose of
determining whether or not any Excess has been contracted for, charged or
received by Lender, all interest at any time contracted for, charged or received
by the Lender in connection with this Agreement shall be amortized, prorated,
allocated and spread in equal parts during the entire term of this Agreement.

          (c)  The provisions of Section 3.4 shall be deemed to be incorporated
                                 -----------                                   
into every document or communication relating to the Obligations which sets
forth or prescribes any account, right or claim or alleged account, right or
claim of the Lender with respect to the Borrower (or any other obligor in
respect of Obligations), whether or not any provision of Section 3.4 is referred
                                                         -----------            
to therein.  All such documents and communications and all figures set forth
therein shall, for the sole purpose of computing the extent of the liabilities
and obligations of the Borrower (or other obligor) asserted by the Lender
thereunder, be automatically recomputed by any Borrower or obligor, and by any
court considering the same, to give effect to the adjustments or credits
required by Section 3.4.
            ----------- 

          (d)  If the applicable state or federal law is amended in the future
to allow a greater rate of interest to be charged under this Agreement or any
other Loan Documents than is presently allowed by applicable state or federal
law, then the limitation of interest under Section 3.4 shall be increased to the
                                           ----------- 
maximum rate of interest allowed by applicable state or federal law as amended,
which increase shall be effective hereunder on the effective date of such
amendment, and all interest charges owing to the Lender by reason thereof shall
be payable upon demand.

          3.5  Capital Adequacy.  If as a result of any regulatory change
               ----------------                                          
directly or indirectly affecting Lender or any of Lender's affiliated companies
there shall be imposed, modified or deemed applicable any tax, reserve, special
deposit, minimum capital, capital ratio, or similar requirement against or with
respect to or measured by reference to loans made or to be made to Borrower
hereunder, or to Letters of Credit issued on behalf of Borrower pursuant to the
Letter of Credit Agreement, and the result shall be to increase the cost to
Lender or to any of Lender's affiliated companies of making or maintaining any
Revolving Loan or Letter of Credit hereunder, or reduce any amount receivable in
respect of any such Revolving Loan and which increase in cost, or reduction in
amount receivable, shall be the result of Lender's or Lender's affiliated
company's reasonable allocation among all affected customers of the aggregate of
such increases or reductions resulting from such event, then, within ten (10)
days after receipt by Borrower of a certificate from Lender containing the
information described in this Section 3.5 which shall be delivered to Borrower,
                              -----------                                      
Borrower agrees from time to time to pay Lender such additional amounts as shall
be sufficient to compensate Lender or any of Lender's affiliated companies for
such increased costs or reductions in amounts which Lender determines in
Lender's reasonable discretion are material.  Notwithstanding the foregoing, all
such amounts shall be subject to the provisions of Section 3.4.  The certificate
                                                   -----------                  
requesting compensation under this Section 3.5 shall identify the regulatory
                                   -----------                              
change which has occurred, the requirements which have been imposed, modified or
deemed applicable, the amount of such additional cost or reduction in the amount
receivable and the way in which such amount has been calculated.

          3.6  Unused Line Fee.  For every month during the term of this
               ---------------                                          
Agreement, the Borrower shall pay the Lender a fee (the "Unused Line Fee") in an
                                                         ---------------        
amount equal to one-half of one percent (.50%) per annum, multiplied by the
                                                          -------------    
amount by which (a) the Maximum Borrowing Commitment exceeds (b) the average
closing daily unpaid balance of all revolving loans and all issued but undrawn
letters of credit under all of the LSB-Related Loan Agreements during such
month, with the unpaid balance calculated for this purpose by applying payments
immediately upon receipt.  Such a fee, if any, shall be calculated on the basis
of a year of three hundred sixty (360) days and actual days elapsed, and shall
be payable to the Lender on the first day of each month prior to 

                                       27
<PAGE>
 
the termination of this Agreement commencing January 1, 1998 and on the
termination of this Agreement, with respect to the prior month or portion
thereof.

     4.   PAYMENTS AND PREPAYMENTS.
          ------------------------ 

          4.1  Revolving Loans.  The Borrower shall repay the outstanding
               ---------------                                           
principal balance of the Revolving Loans, plus all accrued but unpaid interest
thereon, upon the termination of this Agreement.  In addition, the Borrower
shall pay to the Lender, on demand, the amount by which the unpaid principal
balance of the Revolving Loans at any time exceeds the Availability at such time
(with Availability for this purpose determined as if the amount of the Revolving
Loans were zero).

          4.2  Place and Form of Payments: Extension of Time.  All payments of
               ---------------------------------------------                  
principal, interest, and other sums due to the Lender shall be made at the
Lender's address set forth in Section 13.10.  Except for Proceeds received
                              -------------                               
directly by the Lender, all such payments shall be made in immediately available
funds.  If any payment of principal, interest, or other sum to be made hereunder
becomes due and payable on a day other than a Business Day, the due date of such
payment shall be extended to the next succeeding Business Day and interest
thereon shall be payable at the applicable interest rate during such extension.

          4.3  Apportionment, Application and Reversal of Payments.  Except as
               ---------------------------------------------------            
otherwise expressly provided hereunder, the Lender shall determine in its
discretion the order and manner in which proceeds and other payments that the
Lender receives are applied to the Revolving Loans, interest thereon, and the
other Obligations, and the Borrower hereby irrevocably waives the right to
direct the application of any payment or proceeds; provided, however, unless so
                                                   --------  -------           
directed by the Borrower, the Lender shall not apply any such payments which it
receives to any Eurodollar Rate Loan, except:  (a) on the expiration date of the
Interest Period applicable to any such Eurodollar Rate Loan; or (b) in the
event, and only to the extent, that there are not outstanding Reference Rate
Loans. Following an Event of Default that is continuing, the Lender shall have
the continuing and exclusive right to apply and reverse and reapply any and all
such proceeds and payments to any portion of the Obligations subject to the
terms of this Section 4.3 and the Borrower's right to direct prepayments of
              -----------                                                  
Eurodollar Rate Loans.

          4.4  INDEMNITY FOR RETURNED PAYMENTS.  IF AFTER RECEIPT OF ANY PAYMENT
               -------------------------------                                  
OF, OR PROCEEDS APPLIED TO THE PAYMENT OF, ALL OR ANY PART OF THE OBLIGATIONS,
THE LENDER IS FOR ANY REASON REQUIRED TO SURRENDER SUCH PAYMENT OR PROCEEDS TO
ANY PERSON, BECAUSE SUCH PAYMENT OR PROCEEDS IS INVALIDATED, DECLARED
FRAUDULENT, SET ASIDE, DETERMINED TO BE VOID OR VOIDABLE AS A PREFERENCE, OR A
DIVERSION OF TRUST FUNDS, OR FOR ANY OTHER REASON, THEN:  THE OBLIGATIONS OR
PART THEREOF INTENDED TO BE SATISFIED SHALL BE REVIVED AND CONTINUE AND THIS
AGREEMENT SHALL CONTINUE IN FULL FORCE AS IF SUCH PAYMENT OR PROCEEDS HAD NOT
BEEN RECEIVED BY THE LENDER AND THE BORROWER SHALL BE LIABLE TO PAY TO THE
LENDER, AND HEREBY DOES INDEMNIFY THE LENDER AND HOLD THE LENDER HARMLESS FOR
THE AMOUNT OF SUCH PAYMENT OR PROCEEDS SURRENDERED.  The provisions of this
Section 4.4 shall be and remain effective notwithstanding any contrary action
-----------                                                                  
which may have been taken by the Lender in 

                                       28
<PAGE>
 
reliance upon such payment or Proceeds, and any such contrary action so taken
shall be without prejudice to the Lender's rights under this Agreement and shall
be deemed to have been conditioned upon such payment or Proceeds having become
final and irrevocable. The provisions of this Section 4.4 shall survive the
                                              -----------
termination of this Agreement.


     5.   LENDER'S BOOKS AND RECORDS:  MONTHLY STATEMENTS.  The Borrower agrees
          -----------------------------------------------                      
that the Lender's books and records showing the Obligations and the transactions
pursuant to this Agreement and the other Loan Documents shall be admissible in
any action or proceeding arising therefrom irrespective of whether any
Obligation is also evidenced by a promissory note or other instrument, and shall
constitute presumptive proof thereof until such time as Borrower has reviewed
the monthly statement as hereinafter provided.  The Lender will provide to the
Borrower a monthly statement of Loans, payments, and other transactions pursuant
to this Agreement.  Such statement shall be deemed correct, accurate, and
binding on the Borrower and as an account stated and shall constitute prima
facie proof thereof (except for reversals and reapplications of payments made as
provided in Section 4.3 and corrections of errors discovered by the Lender),
            -----------                                                     
unless the Borrower notifies the Lender in writing to the contrary within thirty
(30) days after such statement is rendered.  In the event a timely written
notice of objections is given by the Borrower, only the items to which exception
is expressly made will be considered to be disputed by the Borrower.

     6.   COLLATERAL.
          ---------- 

          6.1  Grant of Security Interest.
               -------------------------- 

          (a)  As security for the Obligations, each Borrower hereby grants to
the Lender a continuing security interest in, lien on, and assignment of: (i)
all Receivables, Inventory, Proprietary Rights, and Proceeds, wherever located
and whether now existing or hereafter arising or acquired; (ii) all moneys,
securities and other property and the Proceeds thereof, now or hereafter held or
received by, or in transit to, the Lender from or for the Borrower, whether for
safekeeping, pledge, custody, transmission, collection or otherwise, including,
without limitation, all of the Borrower's deposit accounts, credits and balances
with the Lender and all claims of the Borrower against the Lender at any time
existing; (iii) all of Borrower's deposit accounts containing Collateral with
any financial institutions with which Borrower maintains deposits; and (iv) all
books, records, ledger cards, data processing records, computer software and
other property and general intangibles at any time evidencing or relating to the
Receivables, Inventory, Proprietary Rights, Proceeds, and other property
referred to above (all of the foregoing, together with all other property in
which Lender may at any time be granted a Lien, being herein collectively
referred to as the "Collateral").  The Lender shall have all of the rights of a
                    ----------                                                 
secured party with respect to the Collateral under the UCC and other applicable
laws.

          (b)  All Obligations shall constitute a single loan secured by all of
the Collateral. The Lender may, in its sole discretion, (i) exchange, waive, or
release any of the Collateral, (ii) after the occurrence of an Event of Default
that is continuing, apply Collateral and direct the order or manner of sale
thereof as the Lender may determine, and (iii) after the occurrence of an Event
of Default that is continuing, settle, compromise, collect, or otherwise
liquidate any Collateral in any 

                                       29
<PAGE>
 
manner, all without affecting the Obligations or the Lender's right to take any
other action with respect to any other Collateral.

          6.2  Perfection and Protection of Security Interest.  Each Borrower
               ----------------------------------------------                
shall, at its expense, perform all steps requested by the Lender at any time to
perfect, maintain, protect, and enforce the Security Interest in the Collateral
including, without limitation: (a) executing and recording of the Patent and
Trademark Assignments and executing and filing financing or continuation
statements, and amendments thereof, relating to the Collateral in form and
substance satisfactory to the Lender; (b) delivering to the Lender, upon
Lender's request therefor, the originals of all instruments, documents, and
chattel paper, and all other Collateral of which the Lender determines it should
have physical possession in order to perfect and protect the Security Interest
therein, duly endorsed or assigned to the Lender without restriction; (c)
delivering to the Lender warehouse receipts covering any portion of the
Collateral located in warehouses and for which warehouse receipts are issued;
(d) after an Event of Default that is continuing, placing notations on the
Borrower's books of account to disclose the Security Interest; (e) delivering to
the Lender, upon Lender's request therefor, all letters of credit on which the
Borrower is a named beneficiary; (f) after an Event of Default that is
continuing, transferring Inventory to warehouses designated by the Lender; and
(g) taking such other steps as are deemed necessary by the Lender to maintain
the Security Interest. The Lender may file, without the Borrower's signature,
one or more financing statements disclosing the Security Interest. The Borrower
agrees that a carbon, photographic, photostatic, or other reproduction of this
Agreement or of a financing statement is sufficient as a financing statement. If
any Collateral is at any time in the possession or control of any warehouseman,
bailee or any of the Borrower's agents or processors, then the Borrower shall
notify the Lender thereof and shall notify such Person of the Security Interest
in such Collateral and, upon the Lender's request following an Event of Default
that is continuing, instruct such Person to hold all such Collateral for the
Lender's account subject to the Lender's instructions. If at any time any
Collateral is located on any premises that are not owned by the Borrower, then
the Borrower shall obtain written waivers, in form and substance reasonably
satisfactory to the Lender, of all present and future Liens to which the owner
or lessor of such premises may be entitled to assert against the Collateral.
From time to time, the Borrower shall, upon Lender's request, execute and
deliver confirmatory written instruments pledging to the Lender the Collateral,
but the Borrower's failure to do so shall not affect or limit the Security
Interest. So long as this Agreement is in effect and until all Obligations have
been fully satisfied, the Security Interest shall continue in full force and
effect in all Collateral (whether or not deemed eligible for the purpose of
calculating the Availability or as the basis for any advance, loan, or other
financial accommodation). Upon termination of this Agreement and payment of all
Obligations, the Lender shall release all Security Interests held by the Lender.

          6.3  Location of Collateral.  Each Borrower represents and warrants to
               ----------------------                                           
the Lender that: (a) Exhibit D hereto is a correct and complete List of the
                     ---------                                             
Borrower's chief executive office, the location of its books and records, the
locations of the Collateral, and the locations of all of its other places of
business; and (b) Exhibit H correctly identifies any of such facilities and
                  ---------                                                
locations that are not owned by the Borrower and sets forth the names of the
owners and lessors of, and, to the best of the Borrower's knowledge, the holders
of any mortgages on such facilities and locations.  Except for Inventory that is
consigned by a Borrower to a customer or warehouse, the Borrower agrees that it
will not maintain any Collateral at any location other than those listed on
Exhibit D, and it will not 
---------

                                       30
<PAGE>
 
otherwise change or add to any of such locations, unless it gives the Lender at
least thirty (30) days prior written notice and executes such financing
statements and other documents that the Lender requests in connection therewith.

          6.4   Title to, Liens on, and Sale and Use of Collateral.  Each
                --------------------------------------------------       
Borrower represents and warrants to the Lender that: (a) all Collateral is and
will continue to be owned by the Borrower free and clear of all Liens
whatsoever, except for the Security Interest and other Permitted Liens; (b) the
Security Interest will not be subject to any prior Lien except the Permitted
Liens; (c) the Borrower will use, store, and maintain the Collateral with all
reasonable care and will use the Collateral for lawful purposes only; and (d)
the Borrower will not, without the Lender's prior written approval, sell, or
dispose of or permit the sale or disposition of any Collateral, except for (i)
sales of Inventory in the ordinary course of business, and (ii) as otherwise
provided or allowed by this Agreement or any of the other Loan Documents. The
inclusion of Proceeds in the Collateral shall not be deemed the Lender's consent
to any sale or other disposition of the Collateral except as expressly permitted
herein.

          6.5   Appraisals. Following the occurrence of an Event of Default that
                ----------
is continuing, each Borrower shall, at the request of the Lender, provide the
Lender, at the Borrower's expense, with appraisals or updates thereof of any or
all of the Collateral from an appraiser satisfactory to the Lender.

          6.6   Access and Examination.  The Lender may at all reasonable times
                ----------------------                                         
have access to, examine, audit, make extracts from and inspect the Borrower's
records, files, and books of account and the Collateral and may discuss the
Borrower's affairs with the Borrower's officers and management.  The Borrower
will deliver to the Lender any instrument necessary for the Lender to obtain
records from any service bureau maintaining records for the Borrower.  The
Lender may, at any time when an Event of Default exists and at the Borrower's
expense, make copies of all of the Borrower's books and records, or require the
Borrower to deliver such copies to the Lender.  After the occurrence of an Event
of Default that is continuing, the Lender may, without expense to the Lender,
use such of the Borrower's personnel, supplies, and premises as may be
reasonably necessary for maintaining or enforcing the Security Interest.  Lender
shall have the right, at any time, in Lender's name or in the name of a nominee
of the Lender, to verify the validity, amount or any other matter relating to
the Accounts, by mail, telephone, or otherwise.

          6.7   Insurance.  The Borrower shall insure the Collateral and its
                ---------                                                   
Equipment against loss or damage by fire with extended coverage, theft,
burglary, pilferage, loss in transit, and such other hazards as the Lender shall
specify, in amounts, under policies and by insurers acceptable to the Lender.
Borrower shall also maintain flood insurance, in the event of a designation of
the area in which any Real Property is located as "flood prone" or a "flood risk
area," as defined by the Flood Disaster Protection Act of 1973, in an amount to
be reasonably determined by Lender, and shall comply with the additional
requirements of the National Flood Insurance Program as set forth therein. The
Borrower shall cause the Lender to be named in each such policy as secured party
of the Inventory that constitutes part of the Collateral and loss payee or
additional insured, in a manner acceptable to the Lender, as to the Collateral.
Each policy of insurance shall contain a clause or endorsement requiring the
insurer to give not less than thirty (30) days prior written notice to the
Lender in the event of cancellation of the policy for any reason whatsoever and
a clause or 

                                       31
<PAGE>
 
endorsement stating that the interest of the Lender shall not be impaired or
invalidated by any act or neglect of the Borrower or the owner of any premises
where Collateral is located nor by the use of such premises for purposes more
hazardous than are permitted by such policy. All premiums for such insurance
shall be paid by the Borrower when due, and certificates of insurance and, if
requested, photocopies of the policies shall be delivered to the Lender. If the
Borrower fails to procure such insurance or to pay the premiums therefor when
due, the Lender may (but shall not be required to) do so and charge the costs
thereof to the Borrower's loan account. After becoming aware of any loss, damage
or destruction to Collateral, the Borrower shall promptly notify the Lender of
any such loss, damage, or destruction that exceeds $200,000, whether or not
covered by insurance. The Lender is hereby authorized to collect all insurance
proceeds directly following the occurrence of an Event of Default that is
continuing. After deducting from such proceeds the expenses, if any, incurred by
Lender in the collection or handling thereof, if an Event of Default has
occurred and is continuing, the Lender may apply such proceeds to the reduction
of the Obligations, in such order as Lender determines, or at the Lender's
option may permit or require the Borrower to use such money, or any part
thereof, to replace, repair, restore or rebuild the Collateral in a diligent and
expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction. If no Event of
Default has occurred and is continuing, Lender hereby authorizes Borrower to
collect all such insurance proceeds and to use such money, or any part thereof,
to replace, repair, restore or rebuild the Collateral in a diligent and
expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction.

          6.8   Collateral Reporting.  The Borrower will provide the Lender with
                --------------------                                            
the following documents at the following times in form satisfactory to the
Lender:  (a) on a daily basis, a schedule of Accounts created since the last
such schedule, a schedule of remittance advices, credit memos and reports and a
schedule of collections of Accounts since the last such schedule; (b) no later
than fifteen (15) days after the last day of each month, monthly summary and
detailed agings of Accounts aged by due date and by invoice date; (c) no later
than twenty (20) days after the last day of each month, monthly reconciliations
of Accounts balances per the aging to the general ledger accounts receivable
balance and to the financial statements provided to Lender under Section 7.2(c);
                                                                 -------------- 
(d) no later than twenty (20) days after the last day of each month, monthly
Inventory reports by category and by location; (e) no later than twenty (20)
days after the last day of each month, monthly reconciliations of the detailed
Inventory reports to the general ledger and to the financial statements provided
to Lender under Section 7.2(c); (f) upon request, copies of invoices, credit
                --------------                                              
memos, shipping and delivery documents, purchase orders; (g) such other reports
as to the Collateral as the Lender shall request from time to time; and (h)
certificates of an officer of the Borrower certifying as to the foregoing.  If
any of the Borrower's records or reports of the Collateral are prepared by an
accounting service or other agent, the Borrower hereby authorizes such service
or agent to deliver such records, reports, and related documents to the Lender.

          6.9   Accounts.  (a) Each Borrower hereby represents and warrants to
                --------                                                      
the Lender that: (i) each existing Account represents, and each future Account
will represent, a bona fide sale or lease and delivery of goods by the Borrower,
                  ---- ----                                                     
or rendition of services by the Borrower, in the ordinary course of the
Borrower's business; (ii) each existing Account is, and each future Account will
be, for a liquidated amount payable by the Account Debtor thereon on the terms
set forth in the invoice therefor or in the schedule thereof delivered to the
Lender, without offset, deduction, 

                                       32
<PAGE>
 
defense, or counterclaim (other than claims relating to warranty issues); (iii)
no payment will be received with respect to any Account, and no credit,
discount, or extension, or agreement therefor will be granted to any Account,
except as reported to or otherwise agreed to by the Lender in accordance with
this Agreement; (iv) each copy of an invoice requested by and delivered to the
Lender by the Borrower will be a genuine copy of the original invoice sent to
the Account Debtor named therein; and (v) all goods described in each invoice
will have been delivered to the Account Debtor and all services of the Borrower
described in each invoice will have been performed, except where the Account
Debtor has previously agreed in writing to accept billings for such goods.


          (b)   The Borrower shall not re-date any invoice or sale or make sales
on extended dating beyond that customary in the Borrower's business or extend or
modify any Account which alters its eligibility status, or, with respect to
ineligible Accounts, which are inconsistent with prudent business practice and
industry standards.  If the Borrower becomes aware of any matter adversely
affecting any Account in an amount in excess of $100,000, including information
regarding the Account Debtor's creditworthiness, the Borrower will promptly so
advise the Lender.

          (c)   The Borrower shall not accept any note or other instrument
(except a check or other instrument for the immediate payment of money) with
respect to any Eligible Account without the Lender's written consent. If the
Lender consents to the acceptance of any such instrument, it shall be considered
as evidence of the Account and not payment thereof and the Borrower will upon
Lender's request, promptly deliver such instrument to the Lender appropriately
endorsed. Regardless of the form of presentment, demand, notice of dishonor,
protest, and notice of protest with respect thereto, the Borrower will remain
liable thereon until such instrument is paid in full.

          (d)   The Borrower shall notify the Lender promptly of all disputes
and claims with an Account Debtor relating to an Eligible Account that exceeds
$100,000 and when no Event of Default exists hereunder, may settle or adjust
them at no expense to the Lender, but no discount, credit or allowance in excess
of $100,000 shall be granted to any Account Debtor without the Lender's consent,
except for discounts, credits and allowances made or given in the ordinary
course of the Borrower's business. The Borrower shall send the Lender a copy of
each credit memorandum in excess of $100,000 as soon as issued. The Lender may,
at all times when an Event of Default exists hereunder, settle or adjust
disputes and claims directly with Account Debtors for amounts and upon terms
which the Lender considers advisable and, in all cases, the Lender will credit
the Borrower's loan account with only the net amounts received by the Lender in
payment of any Accounts.

          6.10  Collection of Accounts. (a) Until the occurrence of an Event of
                ---------------------- 
Default that is continuing, the Borrower shall collect all Accounts, shall
receive all payments relating to Accounts, and shall promptly deposit all such
collections into a Payment Account established for the account of the Borrower
at a bank acceptable to the Borrower and the Lender. All collections relating to
Accounts received in any such Payment Account or directly by the Borrower or the
Lender, and all funds in any Payment Account or other account to which such
collections are deposited, shall be the sole property of the Lender and subject
to the Lender's sole control. After the occurrence of an Event of Default that
is continuing, the Lender may, at any time, notify obligors that the Accounts
have been assigned to the Lender and of the Security Interest therein, and may
collect

                                       33
<PAGE>
 
them directly and charge the collection costs and expenses to the Borrower's
loan account. After the occurrence of an Event of Default that is continuing,
the Borrower, at Lender's request, shall execute and deliver to the Lender such
documents as the Lender shall require to grant the Lender access to any post
office box in which collections of Accounts are received.

          (a)   If sales of Inventory are made for cash, the Borrower shall
immediately deliver to the Lender the identical checks, cash, or other forms of
payment which the Borrower receives.

          (b)   All payments received by the Lender on account of Accounts or as
Proceeds of other Collateral will be the Lender's sole property and will be
credited to the Borrower's loan account (conditional upon final collection)
after allowing one (1) Business Day for collection.

          (c)   In the event the Borrower repays all of the Obligations upon the
termination of this Agreement, other than through the Lender's receipt of
payments on account of Accounts or Proceeds of other Collateral, such payment
will be credited (conditional upon final collection) to the Borrower's loan
account one (1) Business Day after the Lender's receipt thereof.

          6.11  Inventory.  Each Borrower represents and warrants to the
                ---------                                               
Lender that all of the Inventory is and will be held for sale or lease, or to be
furnished in connection with the rendition of services, in the ordinary course
of the Borrower's business, and is and will be fit for such purposes. The
Borrower will keep the Inventory in good and marketable condition, at its own
expense.  The Borrower agrees that all Inventory produced by the Borrower in the
United States will be produced in accordance with the Federal Fair Labor
Standards Act of 1938.  The Borrower will conduct a physical count of the
Inventory at least once per Fiscal Year, except as otherwise agreed to between
the Lender and the Borrower, and will, upon request of the Lender, supply the
Lender with a copy of such count accompanied by a report of the value of such
Inventory (valued at the lower or cost, on a first-in, first-out basis, or
market value).  The Borrower will not, without the Lender's written consent,
sell any Inventory on a bill and hold basis (except as provided in subsection
(xiii) of the definition of Eligible Accounts set forth in this Agreement),
guaranteed sale, sale and return, sale on approval, consignment, or other
repurchase or return basis.

          6.12  Documents and Instruments. Each Borrower represents and warrants
                -------------------------
to the Lender that: (a) all Documents and Instruments describing, evidencing, or
constituting Collateral, and all signatures and endorsements thereon, are and
will be complete, valid, and genuine and (b) all goods evidenced by such
Documents and Instruments were, at the time of their sale, owned by the Borrower
free and clear of all Liens other than Permitted Liens.

          6.13  Right to Cure. The Lender may in its sole discretion pay any
                -------------
amount or do any act required of the Borrower hereunder in order to preserve,
protect, maintain or enforce the Obligations, the Collateral or the Security
Interest, and which the Borrower fails to pay or do, including, without
limitation, payment of any judgment against the Borrower, any insurance premium,
any warehouse charge, processing charge, any landlord's claim, and any other
Lien upon the Collateral. All payments that the Lender makes under this Section
                                                                        -------
6.13 and all out-of-pocket costs and expenses that the Lender pays or incurs in
----
connection with any action, taken by it hereunder shall be charged to the
Borrower's loan account; provided that Lender will make a good

                                       34
<PAGE>
 
faith effort to notify the Borrower and provide the Borrower with a written,
itemized invoice covering such charge. Any payment made or other action taken by
the Lender under this Section 6.13 shall be without prejudice to any right
Lender may have to assert an Event of Default hereunder and to proceed
accordingly.

          6.14  Power of Attorney. Each Borrower appoints the Lender and the
                -----------------
Lender's designees as the Borrower's attorney, with power: (a) to endorse the
Borrower's name on any checks, notes, acceptances, money orders, or other forms
of payment or security that come into the Lender's possession; (b) to sign the
Borrower's name on any invoice, bill of lading, or other document of title
relating to any Collateral, on drafts against customers, on assignments of
Accounts, on notices of assignment, financing statements and other public
records and on verifications of Accounts to Account Debtors; (c) to notify the
post office authorities, when an Event of Default exists, to change the address
for delivery of the Borrower's mail to an address designated by the Lender and
to receive, open and dispose of all mail addressed to the Borrower; (d) to send
requests for verification of Accounts to Account Debtors; and (e) to do all
things necessary to carry out this Agreement. The Borrower ratifies and approves
all acts of such attorney. Neither the Lender nor the attorney will be liable
for any acts or omissions or for any error of judgment or mistake of fact or
law. This power, being coupled with an interest, is irrevocable until this
Agreement has been terminated and the Obligations have been fully satisfied.

          6.15  Lender's Rights, Duties, and Liabilities. Each Borrower assumes
                ----------------------------------------
all responsibility and liability arising from or relating to the use, sale or
other disposition of the Collateral. Neither the Lender nor any of its officers,
directors, employees, and agents shall be liable or responsible in any way for
the safekeeping of any of the Collateral, or for any act or failure to act with
respect to the Collateral, or for any loss or damage thereto, or for any
diminution in the value thereof, or for any act of default by any warehouseman,
carrier, forwarding agency or, other person whomsoever, all of which shall be at
the Borrower's sole risk. The Obligations shall not be affected by any failure
of the Lender to take any steps to perfect the Security Interest or to collect
or realize upon the Collateral, nor shall loss of or damage to the Collateral
release the Borrower from any of the Obligations. After the occurrence of an
Event of Default that has not been cured or otherwise waived by Lender, the
Lender may (but shall not be required to), without notice to or consent from the
Borrower, sue upon or otherwise collect, extend the time for payment of, modify
or amend the terms of, compromise or settle for cash or credit, grant other
indulgences, extensions, renewals, compositions, or releases, and take or omit
to take other action with respect to the Collateral, any security therefor, any
agreement relating thereto, any insurance applicable thereto, or any Person
liable directly or indirectly in connection with any of the foregoing, without
discharging or otherwise affecting the liability of the Borrower for the
Obligations.

          6.16  Release of Collateral and Borrower.  Upon payment in full of
                ----------------------------------                          
all Obligations, Lender shall immediately release its Security Interest in and
to all of the Collateral.

          7.1   Books and Records.  Each Borrower shall maintain, at all times,

Borrower shall, by means of appropriate entries, reflect in such accounts and in
all Financial Statements proper liabilities and reserves for all taxes and
proper provision for depreciation and amortization of Property and bad debts,
all in accordance with GAAP. The Borrower shall maintain at all times books and
records pertaining to the Collateral in such detail, form, and scope as the
Lender shall reasonably require, including without limitation records of:  (a)
all payments received and all credits and extensions granted with respect to the
Accounts; (b) the return, repossession, stoppage in transit, loss, damage, or
destruction of any Inventory; and (c) all other dealings affecting the
Collateral.

          7.2   Financial Information.  Each Borrower shall promptly furnish to
                ---------------------                                          
the Lender all such financial information as the Lender shall reasonably

that examined such statements to the effect that they have reviewed and are
familiar with the Loan Documents and that, in examining such Financial
Statements, they did not become aware of any fact or condition which then

Documents are not correct and complete as of the date of such certificate and
(B) no Event of Default then exists or existed during the period covered by such
Financial Statements. If such certificate discloses that a representation or
warranty is not correct or complete, or that a covenant has not been complied

thereto.

meaning given to it in the definition of Affiliate herein);

          (n)  any event or condition shall occur, or exist with respect to a
Plan that would, in the Lender's reasonable judgment, subject the Borrower to
any tax, penalty or other liabilities under the terms of the Plan, under ERISA
or under the Code which in the aggregate are material in relation to the
business, operations, Property or financial or other condition of the CCI
Consolidated Group taken as a whole;

          (o)  there occurs after the date hereof an Ownership Change (as
defined below) in LSB. For purposes of this Agreement, an "Ownership Change" in
LSB is deemed to have occurred if any Person (except Jack E. Golsen, members of
his Immediate Family [as defined below] and any entity controlled by Jack E.
Golsen or members of his Immediate Family), together with such Person's
affiliates and associates, is or becomes the beneficial owner, directly or
indirectly, of more than fifty percent (50%) of the outstanding Common Stock of
LSB. The term "Immediate Family" of any Person means the spouse, siblings,
children, mothers and mothers-in-law, fathers and fathers-in-law, sons and
daughters-in-law, daughters and sons-in-law, nieces, nephews, brothers and
sisters-in-law, sisters and brothers -in-law; and

          (p)  any "event of default" (as such term is defined in the Bond

          11.2 Remedies.

                                       51
<PAGE>
 
          (a)  If an Event of Default exists, the Lender may, without notice to
or demand on the Borrower, do one or more of the following at any time or times
and in any order: (i) reduce the amount of or refuse to make Revolving Loans and
restrict or refuse to arrange for Letters of Credit; (ii) terminate this
Agreement; (iii) declare any or all Obligations to be immediately due and
payable (provided however that upon the occurrence of any Event of Default
described in Sections 11.1(f), 11.1(g), or 11.1(h), all Obligations shall
             -------------------------------------
automatically become immediately due and payable); and (iv) pursue its other
rights and remedies under the Loan Documents and applicable law. The foregoing
shall not be construed to limit the Lender's discretion to take the actions
described in clause (i) of this subparagraph (a) at any other time.

          (b)  If an Event of Default exists: (i) the Lender shall have, in
addition to all other rights, the rights and remedies of a secured party under
the UCC; (ii) the Lender may, at any time, take possession of the Collateral and
keep it on the Borrower's premises, at no cost to the Lender, or remove any part
of it to such other place or places as the Lender may desire, or, the Borrower
shall, upon the Lender's demand, at the Borrower's cost, assemble the Collateral
and make it available to the Lender at a place reasonably convenient to the
Lender; and (iii) the Lender may sell and deliver any Collateral at public or
private sales, for cash, upon credit or otherwise, at such prices and upon such
terms as the Lender deems advisable, in its sole discretion, and may, if the
Lender deems it reasonable, postpone or adjourn any sale of the Collateral by an
announcement at the time and place of sale or of such postponed or adjourned
sale without giving a new notice of sale. Without in any way requiring notice to
be given in the following manner, the Borrower agrees that any notice by the
Lender of sale, disposition or other intended action hereunder or in connection
herewith, whether required by the UCC or otherwise, shall constitute reasonable
notice to the Borrower if such notice is mailed by registered or certified mail,
return receipt requested, postage prepaid, or is delivered personally against
receipt, at least five (5) days prior to such action to the Borrower's address
specified in or pursuant to Section 13.10. If any Collateral is sold on terms
                            ------------- 
other than payment in full at the time of sale, no credit shall be given against
the Obligations until the Lender receives payment, and if the buyer defaults in
payment, the Lender may resell the Collateral without further notice to the
Borrower. In the event the Lender seeks to take possession of all or any portion
of the Collateral by judicial process, the Borrower irrevocably waives: (a) the
posting of any bond, surety or security with respect thereto which might
otherwise be required; (b) any demand for possession prior to the commencement
of any suit or action to recover the Collateral; and (c) any requirement that
the Lender retain possession and not dispose of any Collateral until after trial
or final judgment. The Borrower agrees that the Lender has no obligation to
preserve rights to the Collateral or marshal any Collateral for the benefit of
any Person. Following the occurrence of an Event of Default that is continuing,
the Lender is hereby granted a license or other right to use, without charge,
the Borrower's labels, patents, copyrights, name, trade secrets, trade names,
trademarks, and advertising matter or any similar property, in completing
production of, advertising or selling any Collateral, and the Borrower's rights
under all licenses and all franchise agreements shall inure to the Lender's
benefit, as long as such does not violate in any manner such other loan
agreements that may be in place at such time. The proceeds of sale shall be
applied first to all expenses of sale, including attorneys' fees, and second, in
whatever order the Lender elects, to all Obligations. The Lender will return any
excess to the Borrower and the Borrower shall remain liable for any deficiency.

                                       52
<PAGE>
 
          (c)  If an Event of Default occurs and is continuing, the Borrower
hereby waives: (i) all rights to notice and hearing prior to the exercise by the
Lender of the Lender's rights to repossess the Collateral without judicial
process or to replevy, attach or levy upon the Collateral without notice or
hearing, and (ii) all rights of set-off and counterclaim against Lender.

          (d)  If the Lender terminates this Agreement upon an Event of Default
that has not been cured or otherwise waived to Lender's satisfaction, the
Borrower shall pay the Lender, immediately upon termination, an early
termination penalty equal to the early termination fee that would have been
payable under Article 12 if this Agreement had been terminated on that date
              ----------                                                   
pursuant to the Borrower's election.

     12.  TERM AND TERMINATION.  The term of this Agreement shall extend until
          --------------------                                                
December 31, 2000 (the "Termination Date"). This Agreement shall automatically
be renewed thereafter for successive terms of thirteen (13) months each, unless
this Agreement is terminated as provided below. The Lender and the Borrower
shall each have the right to terminate this Agreement, without premium or
penalty, at the end of the initial term or at the end of any renewal term by
giving the other written notice not less than sixty (60) days prior to the end
of such term by registered or certified mail. The Borrower may also terminate
this Agreement at any time during its initial term or any renewal periods if:
(a) it gives the Lender sixty (60) days prior written notice of termination by
registered or certified mail; (b) it pays and performs all Obligations on or
prior to the effective date of termination; and (c) except as otherwise provided
herein, it pays the Lender, on or prior to the effective date of termination,
one percent (1%) of the average daily balance of the Revolving Loans and Letters
of Credit outstanding under this Agreement for the preceding one hundred eighty
day (180) day period (or from the Closing Date up to and including the date of
termination if less than one hundred eighty (180) days from the Closing Date) if
such termination is made on or prior to the Termination Date. The Lender may
also terminate this Agreement without notice upon an Event of Default that has
not been cured or otherwise waived to Lender's satisfaction. Upon the effective
date of termination of this Agreement for any reason whatsoever, all Obligations
shall become immediately due and payable. Notwithstanding the termination of
this Agreement, until all Obligations are paid and performed in full, the Lender
shall retain all its rights and remedies hereunder (including, without
limitation, in all then existing and after-arising Collateral).

     13.  MISCELLANEOUS.
          ------------- 

          13.1 Cumulative Remedies; No Prior Recourse to Collateral. The
               ---------------------------------------------------- 
enumeration herein of the Lender's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that the Lender may have under the
UCC or other applicable law. The Lender shall have the right, in its sole
discretion, to determine which rights and remedies are to be exercised and in
which order. The exercise of one right or remedy shall not preclude the exercise
of any others, all of which shall be cumulative. The Lender may, without
limitation, proceed directly against the Borrower to collect the Obligations
without any prior recourse to the Collateral.

          13.2 No Implied Waivers. No act, failure or delay by the Lender shall
               ------------------
constitute a waiver of any of its rights and remedies. No single or partial
waiver by the Lender of any provision of this Agreement, or any other Loan
Document, or of breach or default hereunder or thereunder, or 

                                       53
<PAGE>
 
of any right or remedy which the Lender may have, shall operate as a waiver of
any other provision, breach, default, right or remedy or of the same provision,
breach, default, right or remedy on a future occasion. No waiver by the Lender
shall affect its rights to require strict performance of this Agreement.

          13.3   Severability.  If any provision of this Agreement shall be
                 ------------                                              
prohibited or invalid, under applicable law, it shall be effective only to such
extent, without invalidating the remainder of this Agreement.

          13.4   Governing Law. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE
                 -------------
IN THE STATE OF OKLAHOMA AND SHALL BE GOVERNED BY AND INTERPRETED IN ACCORDANCE
WITH THE LAWS OF SUCH STATE EXCEPT THAT NO DOCTRINE OF CHOICE OF LAW SHALL BE
USED TO APPLY THE LAWS OF ANY OTHER STATE OR JURISDICTION.

          13.5   Consent to Jurisdiction and Venue; Service of Process.
                 ----------------------------------------------------- 

          The Borrower agrees that, in addition to any other courts that may
have jurisdiction under applicable laws, any action or proceeding to enforce or
arising out of this Agreement or any of the other Loan Documents may be
commenced in the appropriate court of the State of Oklahoma for Oklahoma County,
or in the United States District Court for the Western District of Oklahoma, and
each Borrower consents and submits in advance to such jurisdiction and agrees
that venue will be proper in such courts on any such matter. Borrower hereby
waives personal service of process and agrees that a summons and complaint
commencing an action or proceeding in any such court shall be properly served
and shall confer personal jurisdiction if served by registered or certified mail
to the Borrower. Should the Borrower fail to appear or answer any summons,
complaint, process or papers so served within thirty (30) days after the mailing
or other service thereof, it shall be deemed in default and an order or judgment
may be entered against it as demanded or prayed for in such summons, complaint,
process or papers. The choice of forum set forth in this section shall not be
deemed to preclude the enforcement of any judgment obtained in such forum, or
the taking of any action under this Agreement to enforce the same, in any
appropriate jurisdiction.

          13.6   Survival of Representations and Warranties.  All of the
                 ------------------------------------------             
Borrower's representations and warranties contained in this Agreement shall
survive the execution, delivery, and acceptance thereof by the parties,
notwithstanding any investigation by the Lender or its agents, but after the
Closing Date it is recognized that such representations and warranties may be
amended from time to time during the term of this Agreement by written agreement
between the Borrower to the Lender due to changes in circumstances.

          13.7   Indemnification. EACH BORROWER HEREBY INDEMNIFIES, DEFENDS AND
                 ---------------
HOLDS LENDER, AND ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES AND COUNSEL,
HARMLESS FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES,
DEFICIENCIES, JUDGMENTS, PENALTIES OR EXPENSES IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST ANY OF THEM, WHETHER DIRECT, INDIRECT OR CONSEQUENTIAL ARISING
OUT OF OR BY REASON OF ANY LITIGATION, INVESTIGATIONS, CLAIMS, OR

                                       54
<PAGE>
 
PROCEEDINGS (WHETHER BASED ON ANY FEDERAL, STATE OR LOCAL LAWS OR OTHER STATUTES
OR REGULATIONS, INCLUDING, WITHOUT LIMITATION, SECURITIES, ENVIRONMENTAL, OR
COMMERCIAL LAWS AND REGULATIONS, UNDER COMMON LAW OR AT EQUITABLE CAUSE, OR ON
CONTRACT OR OTHERWISE) COMMENCED OR THREATENED, WHICH ARISE OUT OF OR ARE IN ANY
WAY BASED UPON THE NEGOTIATION, PREPARATION, EXECUTION, DELIVERY, ENFORCEMENT,
PERFORMANCE OR ADMINISTRATION OF THIS AGREEMENT, ANY OTHER LOAN DOCUMENT, OR ANY
UNDERTAKING OR PROCEEDING RELATED TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY
OR ANY ACT, OMISSION TO ACT, EVENT OR TRANSACTION RELATED OR ATTENDANT THERETO,
INCLUDING, WITHOUT LIMITATION, AMOUNTS PAID IN SETTLEMENT, COURT COSTS, AND THE
FEES AND EXPENSES OF COUNSEL REASONABLY INCURRED IN CONNECTION WITH ANY SUCH
LITIGATION, INVESTIGATION, CLAIM OR PROCEEDING, EXCEPT THAT THIS INDEMNIFICATION
SHALL NOT APPLY TO ANY LOSSES, CLAIMS, DAMAGES, LIABILITIES, JUDGMENTS,
PENALTIES OR EXPENSES IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE LENDER,
AND ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES, OR COUNSEL IF SUCH IS DUE TO AND
ARISES FROM OR IN CONNECTION WITH THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
ANY OF THEM OR THE INTENTIONAL AND WRONGFUL BREACH OF THIS AGREEMENT BY LENDER.
Without limiting the foregoing, if, by reason of any suit or proceeding of any
kind, nature, or description against Borrower, or by Borrower or any other party
against Lender, which in Lender's sole discretion makes it advisable for Lender
to seek counsel for protection and preservation of its liens and security
assets, or to defend its own interest, such reasonable expenses and counsel fees
shall be allowed to Lender. To the extent that the undertaking to indemnify, pay
and hold harmless set forth in this Section 13.7 may be unenforceable because it
                                    ------------    
is violative of any law or public policy, Borrower shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law, to the
payment and satisfaction of all indemnified matters incurred by Lender. The
foregoing indemnity shall survive the payment of the Obligations and the
termination of this Agreement. All of the foregoing costs and expenses shall be
part of the Obligations and secured by the Collateral.

          13.8 Other Security and Guaranties. The Lender may, without, notice or
               ----------------------------- 
demand and without affecting the Borrower's obligations hereunder, from time to
time: (a) take from any Person and hold collateral (other than the Collateral)
for the payment of all or any part of the Obligations and exchange, enforce or
release such collateral or any part thereof; and (b) accept and hold any
endorsement or guaranty of payment of all or any part of the Obligations and
release any such endorser or guarantor, or any Person who has given any Lien in
any other collateral as security for the repayment of all or any part of the
Obligations, or any other Person in any way obligated to pay all or any part of
the Obligations.

          13.9 Fees and Expenses. The Borrower shall pay to the Lender on demand
               -----------------
all costs and expenses that the Lender pays or incurs in connection with the
negotiation, preparation, consummation, administration, enforcement, and
termination of this Agreement and the other Loan Documents, including, without
limitation: (a) attorneys' and paralegals' fees and disbursements of counsel to
the Lender including, without limitation, a reasonable estimate of the allocable
cost of in-

                                       55
<PAGE>
 
house counsel; (b) costs and expenses (including attorneys' and paralegals' fees
and disbursements including, without limitation, a reasonable estimate of the
allocable cost of in-house counsel) for any amendment, supplement, waiver,
consent, or subsequent closing in connection with the Loan Documents and the
transactions contemplated thereby; (c) costs and expenses of lien and title
searches and title insurance; (d) fees and other charges for recording and
filing financing statements and continuations, and other actions to perfect,
protect, and continue the Security Interest; (e) sums paid or incurred to pay
any amount or take any action required of the Borrower under the Loan Documents
that the Borrower was obligated to pay or take under the Loan Documents but
failed to pay or take; (f) the expenses of $500 per Lender's auditor per audit
day plus actual costs of appraisals, inspections, and verifications of the
Collateral, including, without limitation, travel, lodging, and meals, for
inspections of the Collateral and the Borrower's operations by the Lender's
agents up to three times per year and whenever an Event of Default exists; (g)
costs and expenses of forwarding loan proceeds, collecting checks and other
items of payment, and establishing and maintaining Payment Accounts and lock
boxes; (h) all amounts that the Borrower is required to pay under the Letter of
Credit Agreement; (i) costs and expenses of preserving and protecting the
Collateral; and (j) costs and expenses (including attorneys' and paralegals'
fees and disbursements and including, without limitation, a reasonable estimate
of the allocable cost of in-house counsel) paid or incurred to obtain payment of
the Obligations, enforce the Security Interest, sell or otherwise realize upon
the Collateral, and otherwise enforce the provisions of the Loan Documents, or
to defend any claims made or threatened against the Lender arising out of the
transactions contemplated hereby (including without limitation, preparations for
and consultations concerning any such matters). The foregoing shall not be
construed to limit any other provisions of the Loan Documents regarding costs
and expenses to be paid by the Borrower. All of the foregoing costs and expenses
shall be charged to the Borrower's loan account as Revolving Loans.

          13.10  Notices. All notices, demands and requests that either party is
                 -------

the Borrower waives presentment, protest and notice of demand or dishonor and
protest as to any instrument, notice of intent to accelerate and notice of
acceleration, as well as any and all other notices to which it might otherwise
be entitled. No notice to or demand on the Borrower which the Lender may elect

                 --------------------------------------
Agreement shall be binding upon and inure to the benefit of the respective
representatives, successors and assigns of the parties hereto: provided,
however, that no interest herein may be assigned by the Borrower without the
prior written consent of the Lender. The rights and benefits of the Lender

interest in the Obligations or any part thereof. The Borrower agrees that the
Lender may use the Borrower's name in advertising and promotional materials and
in conjunction therewith disclose the general terms of this Agreement.

          13.13  Modification. THIS AGREEMENT IS INTENDED BY THE BORROWER AND
                 ------------ 
THE LENDER TO BE THE FINAL, COMPLETE, AND EXCLUSIVE EXPRESSION OF THE AGREEMENT
BETWEEN THEM. THIS AGREEMENT SUPERSEDES ANY AND ALL PRIOR ORAL OR WRITTEN

EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. NO

counterparts, and by the Lender and the Borrower in separate counterparts, each
of which shall be an original, but all of which shall together constitute one
and the same agreement.

convenience only, are without substantive meaning and should not be construed to
modify, enlarge, or restrict any provision.

          13.16  Right of Set-Off. Whenever an Event of Default exists the
                 ----------------
Lender is hereby authorized at any time and from time to time, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held by Lender or any affiliate of the Lender and other
indebtedness at any time owing by the Lender or any affiliate of the Lender to
or for the credit or the account of the Borrower against any and all of the
Obligations, whether or not then due and payable. Lender agrees promptly to
notify Borrower after any such set-off and application made by Lender, provided
that the failure to give such notice shall not affect the validity of such set-
off and application.

          13.17  Participating Lender's Security Interests. If a Participating
                 -----------------------------------------
Lender shall at any time with the Borrower's knowledge participate with the
Lender in the Loans, the Borrower hereby grants to such Participating Lender,
and the Lender and such Participating Lender shall have and are hereby given, a
continuing lien on and security interest in any money, securities and other
property of the Borrower in the custody or possession of the Participating
Lender, including, the right of set-off, to the extent of the Participating
Lender's participation in the Obligations, and such Participating Lender shall
be deemed to have the, same right of set-off, to the extent of the Participating
Lender's participation in the Obligations under this Agreement, as it would have
if it were a direct lender.

          13.18  WAIVER OF JURY TRIAL. LENDER AND EACH BORROWER ACKNOWLEDGE AND
                 --------------------
AGREE THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR THE
RELATIONSHIP ESTABLISHED HEREBY WOULD BE BASED UPON DIFFICULT AND COMPLEX
ISSUES, AND THEREFORE, THE PARTIES AGREE THAT ANY LAWSUIT GROWING OUT OF ANY
SUCH CONTROVERSY WILL BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE
SITTING WITHOUT JURY. TRIAL BY A JUDGE SITTING WITHOUT A JURY WILL FURTHER
RESULT IN THE AVOIDANCE OF DELAYS, A STREAMLINING OF THE PROCEEDINGS INVOLVED
AND, AS A RESULT, WILL MINIMIZE THE EXPENSE OF ANY SUCH LAWSUIT FOR THE BENEFIT
OF BORROWER AND LENDER. BORROWER HEREBY WAIVES TRIAL BY JURY, RIGHTS OF SET-OFF,
AND THE RIGHT TO IMPOSE COUNTERCLAIMS (EXCEPT FOR COMPULSORY COUNTERCLAIMS) IN
ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT
OF THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL,
OR ANY INSTRUMENT OR DOCUMENT DELIVERED PURSUANT HERETO OR THERETO, OR ANY OTHER
CLAIM OR DISPUTE HOWSOEVER ARISING, BETWEEN THE BORROWER, AND THE LENDER.
BORROWER HEREBY CONFIRMS THAT THE FOREGOING WAIVERS ARE INFORMED AND FREELY
MADE.

          13.19  AMENDMENT AND RESTATEMENT. THIS AGREEMENT AMENDS, EXTENDS AND
                 -------------------------  
RESTATES IN ITS ENTIRETY THE ORIGINAL LOAN AGREEMENTS. THE EXECUTION OF THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS EXECUTED IN CONNECTION HEREWITH DOES NOT
EXTINGUISH THE INDEBTEDNESS OUTSTANDING IN CONNECTION THEREWITH NOR DOES IT
CONSTITUTE A NOVATION WITH RESPECT TO THE INDEBTEDNESS OUTSTANDING IN CONNECTION
WITH THE ORIGINAL LOAN AGREEMENTS. EACH BORROWER REPRESENTS AND WARRANTS THAT AS
OF THE CLOSING DATE THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR
COUNTERCLAIMS TO ITS OBLIGATIONS UNDER THE ORIGINAL LOAN AGREEMENTS OR ANY OTHER
