 SECTION 2. AMOUNT AND TERMS OF LOAN 
  
 2.1 Revolving Loan. The Loans shall be evidenced by the Revolving
Note. Subject to the terms and conditions of this Agreement, the Lender agrees to make Loans to the Borrower from time to time from and including the date hereof to but excluding the Termination Date, up to, but not exceeding at any time the
Commitment; provided, however, that the Lender shall have no obligation to make a Loan if an Event of Default exists or would result from such Loan. The Loans may be outstanding as Daily Reset LIBOR Loans or LIBOR Loans (each, a
“Type of Loan”). Within the limits of the Commitment and subject to the other terms and conditions of this Agreement, the Loans may be borrowed, repaid and reborrowed by the Borrower, in its discretion, from time to time prior to the
Termination Date. The Lender may, with three (3) Business Days prior notice to or the consent of Borrower, make a Loan to pay any principal due under the Loans, any interest due thereon or any fees, cash or expenses due from Borrower to the Lender
under this Agreement. 
  
 2.2 Principal Payments. Unless
earlier payment is required under this Agreement, the Loans shall be due and payable to the Lender on the Termination Date. If at any time the outstanding principal amount of the Loans made by the Lender shall exceed the Commitment, the Borrower
shall forthwith pay to the Lender an amount not less than the amount of any such excess for application to the outstanding principal amount of the Loans. If the Loan Period for any LIBOR Loan should happen to extend beyond the Termination Date, such
LIBOR Loan must be prepaid on the Termination Date. 
  
 2.3
Interest.

the outstanding and unpaid principal amount of each Loan for the period from and including the date of such Loan to but excluding the date such Loan is due, at a rate equal to the Adjusted LIBOR Rate. With respect to Daily 

  

 5 








 
Reset LIBOR Loans, the Adjusted LIBOR Rate shall float daily to account for any changes in the Daily Reset LIBOR Rate. With respect to LIBOR Loans, the
Adjusted LIBOR Rate shall remain fixed for the applicable Loan Period. Upon the occurrence and during the continuance of any Event of Default, the outstanding principal amount of all Loans, and to the extent permitted by applicable law, any interest
payments thereon or any fees or other amounts then due and payable hereunder shall thereafter bear interest (including post-petition interest in any proceeding under Title 11 of the United States Code or other applicable bankruptcy laws) payable
upon demand at the Default Rate. 
  
 (b) Interest
on each Loan shall be calculated on the basis of a year of 360 days and the actual number of days elapsed. 
  
 (c) Accrued interest shall be due and payable in arrears upon any payment of principal or conversion from one Type of Loan to another and
(i) for each Daily Reset LIBOR Loan or a Loan accruing interest at the Prime Rate, on the last day of each calendar quarter, and (ii) for each LIBOR Loan, on the last day of each Loan Period with respect thereto. 
  
 2.4 Borrowings. In order to obtain a Loan, the Borrower shall give the
Lender written notice (which may be a telecopy) of each borrowing to be made hereunder. Each such notice shall be in the form of a “Notice of Borrowing” in substantially the form of Exhibit B hereto, executed by two authorized
officers or representatives of the Borrower, specifying therein (i) the requested date of the proposed Loan, (ii) the aggregate amount of the proposed Loan, and (iii) if a LIBOR Loan, the Loan Period therefor. Subject to the conditions of this
Agreement, the Lender shall make the amount of the Loan available to the Borrower on the date of such Loan in immediately available funds. 
  
 2.5 Prepayments and Conversions. Subject to Section 3.3 hereof, the Borrower shall have the right to make prepayments of principal on any Loan, in
whole or in part, without payment of any penalty or premium, or to convert one Type of Loan into another Type of Loan, at any time or from time to time; provided, however, that each partial prepayment shall be in an amount of at least
$100,000, and if greater than $100,000, an integral multiple of $10,000.00, and if the Loan prepaid or converted is a LIBOR Loan, any conversion or prepayment shall be in the full amount of such LIBOR Loan. The Borrower shall give the Lender notice
of each such prepayment or conversion as provided in Section 2.9. Each such notice shall be in the form of a “Notice of Prepayment” in substantially the form of Exhibit C hereto, specifying therein (i) the date such prepayment will be
made, (ii) the amount of such prepayment and (iii) the Type of Loan being prepaid. The Borrower shall not have the right to convert one Type of Loan into another Type of Loan during the continuance of an Event of Default. 
  
 2.6 Loan Periods; Renewals. 
  
 (a) In the case of each LIBOR Loan, the Borrower shall
select a Loan Period of any duration in accordance with the definition of Loan Period in Section 1.1. 
  
 (b) Provided that no Event of Default has occurred and is continuing, upon notice to the Lender as provided in Section 2.9, the Borrower
may renew any Loan on the 

  

 6 








 
last day of the Loan Period therefor as a Loan with a Loan Period of the same or different duration in accordance with the limitations provided in the
definition of Loan Period in Section 1.1. If the Borrower shall fail to give notice to the Lender of such a renewal or, if an Event of Default has occurred and is continuing, such Loan shall automatically become, as of the last day of the then
current Loan Period, a Loan based upon the same Loan Period as the Loan then expiring. 
  
 2.7 Default Rate. If an “Event of Default” as defined in Section 1.1 shall have occurred and be continuing, the Borrower shall pay interest at the Default Rate. In no event shall the rate of interest
exceed the maximum rate permitted by applicable law. If the Borrower pays to the Lender interest in excess of the amount permitted by applicable law, such excess shall be applied in reduction of the principal balance of the Note, and any remaining
excess interest, after application thereof to the principal balance of the Note, shall be refunded to the Borrower. 
  
 2.8 Payments. All payments (including prepayments) by the Borrower on account of principal, interest and fees shall be made without set-off or
counterclaim to the Lender at its office referred to in Section 9.2 in lawful money of the United States of America and in immediately available funds. 
  
 2.9 Certain Notices. Notices by the Borrower to the Lender pursuant to Section 2.4, each prepayment pursuant to Section 2.5 and each renewal
pursuant to Section 2.6(b) shall be irrevocable and shall be effective only if received by the Lender not later than 10:00 a.m. St. Louis, Missouri time, and (a) in the case of borrowings and prepayments of, conversions into and (in the case of
LIBOR Loans) renewals of (i) Daily Reset LIBOR Loans, given on the Business Day thereof; and (ii) LIBOR Loans, given two (2) Business Days prior thereto. Each such notice shall specify the Loans to be borrowed, prepaid, converted or renewed and the
amount (subject to Section 2.10) and Type of Loans to be borrowed, converted, prepaid or renewed (and in the case of conversion, the Type of Loans to result from such conversion and in the case of LIBOR Loans, the Loan Period therefor) and the date
of the borrowing, prepayment, conversion or renewal (which shall be a Business Day), in the case of a borrowing, such additional information as may be required by Section 2.4. 
  
 2.10 Minimum Amounts. Each Daily Reset LIBOR Loan (or Prime Rate Loan) shall be in the minimum amount of $50,000.00,
and if greater than $50,000.00, an integral multiple of $5,000. Each LIBOR Loan shall be in the minimum amount of $100,000, and if greater than $100,000, an integral multiple of $10,000. In addition, there shall be no more than ten (10) LIBOR Loans
outstanding at any time.

 7 








 SECTION 3. YIELD PROTECTION; ILLEGALITY; ETC. 
  
 3.1 Additional Costs. If the Lender shall determine in good faith
that any Governmental Regulation not presently in effect or applicable to the Lender, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by the
Lender with any new guideline, request or directive of any such authority (whether or not having the force of law), shall (i) affect the basis of taxation of payments to the Lender of any amounts payable by the Borrower under this Agreement or any
other Loan Document (other than taxes imposed on the overall net income of the Lender, by the jurisdiction, or by any political subdivision or taxing authority of any such jurisdiction, in which the Lender has its principal office), or (ii) impose,
modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by the Lender, or (iii) impose any other condition with respect to this Agreement, the
Commitment, the Revolving Note or the Loans, and the result of any of the foregoing is to increase by an amount deemed by the Lender to be material the costs to the Lender of providing the Commitment or making, funding or maintaining any Loan or to
reduce by an amount deemed by the Lender to be material the amount of any sum receivable by the Lender under this Agreement, then the Borrower shall pay to the Lender, such additional amounts as are sufficient to compensate the Lender for such
increased cost or reduced sum receivable. A statement as to the amount of such increased cost or reduced sum receivable, prepared in good faith and in reasonable detail by the Lender and submitted to the Borrower, shall be conclusive and binding for
all purposes absent manifest error in computation. 
  
 3.2
Illegality and Impossibility. 
  
 (a) If
the Lender shall determine in good faith that any Governmental Regulation not presently in effect or applicable to the Lender, or any interpretation or administration thereof by any governmental authority charged with the interpretation or
administration thereof, or compliance by the Lender with any new guideline, request or directive of such authority (whether or not having the force of law), including exchange controls, shall make it unlawful or impossible for the Lender to maintain
any Loan at the LIBOR Rate or the Daily Reset LIBOR Rate under this Agreement, the Borrower shall, upon receipt of notice thereof from the Lender, repay in full to the Lender the then outstanding principal amount of such Loan, together with all
accrued interest thereon to the date of payment and all amounts due to the Lender under Section 3.3: (i) on the last day of the then current Loan Period applicable to a LIBOR Loan if the Lender may lawfully continue to maintain such LIBOR Rate Loan
to such day, or (ii) immediately if the Lender may not continue to maintain such LIBOR Loan or if the Loan is a Daily Reset LIBOR Loan. 
  
 (b) Notwithstanding Section 3.2(a), if such section would otherwise be applicable, but the Lender could lawfully maintain the Loans based
upon the LIBOR Rate or the Daily Reset LIBOR Rate at the Prime Rate, then during such period as the Lender cannot maintain the Loans based upon the LIBOR Rate or the Daily Reset LIBOR Rate, as applicable, such Loans shall bear interest at a per
annum rate equal to the Prime Rate 

  

 8 








 
in effect from time to time less one and one-half of one percent (1.50%) in effect. If all events or conditions making it unlawful or impossible for the
Lender to maintain the Loans based upon the LIBOR Rate or the Daily Reset LIBOR Rate cease to exist, then the Loans shall again bear interest at the Adjusted LIBOR Rate commencing on (i) the first day of the Loan Period immediately following the
date all such events and conditions so cease to exist with respect to LIBOR Loans and (ii) on the day following the date all such events and conditions so cease to exist with respect to Daily Reset LIBOR Loans. 
  
 3.3  LIBOR Rate Indemnity. If the Borrower fails to make any
payment of principal or interest in respect of any Loan based upon a LIBOR Rate when due or makes any payment or prepayment of the principal of any such Loan, for any reason, on any date other than the last day of the Loan Period applicable thereto,
or if the Borrower fails to borrow any Loan based upon the LIBOR Rate after requesting the same in accordance with this Agreement, the Borrower shall reimburse the Lender on demand for any resulting loss or expense incurred by the Lender, including
any loss incurred in obtaining, liquidating or employing deposits from third parties. A statement as to the amount of such loss or expense, prepared in good faith and in reasonable detail by the Lender and submitted to the Borrower, shall be
conclusive and binding for all purposes absent manifest error in computation. Without limiting the foregoing, if a LIBOR Loan is prepaid prior to the end of the Loan Period for such LIBOR Loan, whether voluntarily or because prepayment is required
due to the occurrence of the Termination Date or on account of a default, Borrower agrees to pay all of Lender’s costs, expenses and Interest Differential, as determined by Lender, incurred as a result of such prepayment. 
  
 SECTION 4. REPRESENTATIONS AND WARRANTIES
