Principal and Value. From time to time, beginning October 31, 1997, Lender agrees to lend to Borrower and Borrower agrees to borrow from the Lender an amount to be designated by Borrower, not to exceed $10,000,000.00 outstanding at any one time (each such borrowing, an "Advance"). The loan shall be evidenced by a promissory note in substantially the form of Exhibit "A" attached hereto. All loans and repayments shall be made by Borrower by drawing funds from or depositing funds in Borrower's account at Citibank N.A., New York, New York that will zero balance with the Huls's account at Citibank N.A., New York, New York (Account No. 4070-0001) or such other account of the Lender as it may designate ("designated account"). 3. Term and Maturity. (a) Final Maturity Date. The principal amount of the loan outstanding together with any interest due and outstanding shall be paid by Borrower to the Lender on the Final Maturity Date, or at such later date as may be mutually agreed in writing by the parties. (b) Extension. If the then applicable Final Maturity Date is a date on or before December 31, 2000 and the Borrower may desire that the Lender extend the then applicable Final Maturity Date to the Extension Maturity Date, then (a) the Borrower shall give written notice of said fact (the "Extension Request Notice") to the Lender no later than four (4) months before the Final Maturity Date, (b) the Borrower shall use its best efforts to obtain and enter into on or before the date which is two months prior to the Final Maturity Date a Replacement Financing Arrangement and (c) if the Borrower shall not have entered into a Replacement Financing Arrangement on or before the date which is two months prior to the Final Maturity Date, the Borrower shall deliver to the Lender a certificate of the Borrower (the "Extension Certificate") (x) certifying that the Borrower has not entered into a Replacement Financing Arrangement, but the Borrower used its best efforts to do so as required by clause (b) and setting forth such evidence and back-up detail as necessary to demonstrate the efforts made, including a written letter from each bank from which a Replacement Financing Arrangement as required by clause (b) was requested, indicating that Borrower made such a request and that the request was denied, and (y) requesting that the Final Maturity Date be extended to the Extension Maturity Date.

The Lender shall provide the Borrower with a written notice setting forth the Interest Rate. The Borrower shall be responsible for the payment of any customary commitment fee and other fees in connection with obtaining a Replacement Financing Arrangement. For the avoidance of doubt, in no event shall an Extension Maturity Date be requested by the Borrower after December 31, 2000 or be on a date after December 31, 2001. 4. Rollover Dates. Any amount borrowed hereunder shall be on the basis of daily rollover periods. Each rollover date shall be a banking day in New York, New York ("banking day"). However, should the designated bank designated by the Lender in Section 2 be closed on a banking day, the Lender would not be required to loan money to Borrower nor would Borrower have the option to repay a loan. On the initial and each respective rollover date thereafter, Borrower shall have the option to repay the full principal amount outstanding or any portion thereof, rollover an amount outstanding, or borrow an additional amount provided that the total principal amount will not exceed $10,000,000.00. Borrower will notify Lender of repayments, draw-downs and rollovers by a telefax or memorandum from Borrower, to Lender by 10:00 a.m. Central time on the day money is to be borrowed, or repaid. 5. Interest Rates. Until September 30, 1998, interest shall be calculated at the FED Funds opening rate plus .25% as quoted by VEBA Corporation and supplied by Citibank. On and after October 1, 1998, interest shall be calculated daily at the FED Funds opening rate plus the Applicable Spread as quoted by VEBA Corporation and supplied by Citibank. For loans outstanding on days other than banking days, the interest shall be calculated at the rate applicable for the last preceding banking day. The interest rate shall be furnished daily if there is a loan outstanding. Interest shall accrue on all outstanding amounts and shall be calculated based upon a 360 day year. 6. Payment of Interest. Payments of interest shall be made by wire transfer, or other method of same day settlement, only on banking days, not later than 10:00 a.m. Central time, to the account of Huls, with Citibank N.A., New York, New York, (Account No. 4070-0001) or to such other account of the Lender as it may designate. Interest will be payable monthly, with payment due the day after the Lender notifies Borrower of the amount due for the prior month. 7. Penalty. If Borrower shall borrow, repay or rollover an amount different than which it notifies the Lenders pursuant to paragraph 4, Borrower shall pay to the Lender a penalty equal to the .25% of the amount of the understatement divided by 360. 8. Covenants. So long as any Advance shall remain unpaid or Lender shall have any Commitment hereunder, the Borrower will comply with the Affirmative Covenants set forth in Section 5.01 (on and after the Change of Control Date as defined in the Reference Agreement) and the Negative Covenants (including Negative Pledge) set forth in Section 5.02 of the Reference Agreement, all of which the Borrower, by signing this Agreement, expressly repeats and incorporates herein. 9. Conditions Precedent to each Borrowing. The obligation of Lender to make an Advance on the occasion of each borrowing shall be subject to the condition precedent that no event has occurred and is continuing, or would result from such Advance or from the application of the proceeds therefrom, that 4 constitutes a Default under the Reference Agreement. 10. Events of Default. Each of the Events of Default set forth in Section 6.01 of the Reference Agreement shall constitute an Event of Default hereunder and the Lender shall have the rights with respect to Events of Default and Defaults with respect to the amounts loaned hereunder that are set forth in the Reference Agreement. 11. Assignment. Lender may assign its rights and obligations under this Agreement in whole but not in part and otherwise in accordance with Section 8.07 of the Reference Agreement, provided that any such assignment shall be made to a single Eligible Assignee (as defined in the Reference Agreement). 12. Commitment Fee. The Borrower agrees to pay to the Lender a commitment fee on the unused portion of Lender's commitment from October 1, 1998 in the case of Huls and from the effective date specified in the Assignment and Acceptance pursuant to which it became a Lender in case of each other Lender until the Final Maturity Date at a rate per annum equal to 1/4 of 1%, payable monthly, with payment due the day after the Lender notifies Borrower of the amount due for the prior month. 13. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
