The Borrower has a registered office in Leverkusen, Germany, and is an indirect wholly-owned subsidiary of NL Industries, Inc., a New Jersey corporation ("NL INDUSTRIES"). As of May 30, 1990, and prior to January 1, 1992, the Borrower was a wholly-owned subsidiary of Kronos (US), Inc., a Delaware corporation formerly and then known as Kronos, Inc. ("KRONOS (US)"). Effective as of January 1, 1992, Kronos (US) assigned the Stock of the Borrower to Kronos, Inc., a Delaware corporation formerly (prior to such assignment) known as Kronos (USA), Inc. ("KRONOS") and a subsidiary of Kronos (US), whereupon the Borrower became (and is now) a wholly-owned subsidiary of Kronos. The Borrower, the Banks (or their predecessors in interest), the Agent and Banque Paribas, Co-Agent for the Banks (the "CO-AGENT") were parties to that certain Loan Agreement dated as of May 30, 1990, as amended by that certain (a) First Amendment Agreement (herein so called) dated as of December 31, 1990, (b) Second Amendment Agreement (herein so called) dated as of March 22, 1991, and (c) Third Amendment Agreement (herein so called) dated as of June 15, 1992 (as amended thereby, the "ORIGINAL AGREEMENT"). Pursuant to the Original Agreement, the Borrower requested that the Banks (and/or their predecessors in interest) make, and the Banks (and/or their predecessors in interest) made, advances to the Borrower in Deutsche Mark in the aggregate principal amount of DM 1,600,000,000 on the terms and subject to the conditions and for the purposes set forth in the Original Agreement. Pursuant to the First Amendment Agreement, certain financial covenants in the Original Agreement were amended for the year 1990. Pursuant to the Second Amendment Agreement, INTER ALIA, certain financial covenants in the Original Agreement were amended, the repayment schedule for the Loan was amended and the NL/Kronos Guaranty and the Investment Account Agreement (as defined in the Original Agreement) were executed. Pursuant to the Third Amendment Agreement, INTER ALIA, certain financial covenants in the Original Agreement were amended, the repayment schedule for the Loan was amended, certain U.S. Dollar denominated tranches of the Loan were permitted, the Borrower was given the right to reborrow certain prepayments of the final repayment installment of the Loan and a Liquidity Undertaking was executed by NL Industries and Kronos (US). Effective as of January 1, 1992, the Borrower became a wholly-owned subsidiary of Kronos as explained in the second paragraph of the preamble of this Agreement. 1 During February 1993, the Borrower notified the Agent and the Co-Agent of certain proposed transactions involving its Subsidiaries, certain of which transactions were required to be approved by the requisite Banks. As a result, the First Approval Agreement was executed and the transactions described in the First Approval Agreement have been consummated (except for the transactions referred to in Step 10 of Schedule 1 to the First Approval Agreement, which transactions have not been, and need not be, consummated). The Borrower, the Banks, the Agent and the Co-Agent are parties to that certain Amended and Restated Loan Agreement dated as of October 15, 1993 (the "FIRST RESTATED AGREEMENT"), which amends and restates the Original Agreement. Pursuant to or in connection with the First Restated Agreement, (a) the Agent and the Banks (or their predecessors in interest) were requested by NL Industries, Kronos (US) and Kronos to approve, and did approve, certain transactions pursuant to which NL Industries assigned, contributed or otherwise transferred the Stock of Kronos (US) to Kronos and Kronos (US) assigned or otherwise transferred the Stock of Kronos to NL Industries, (b) a substantial prepayment of the Loan was made from proceeds of a public debt offering made by NL Industries and the maturity of the principal amount of the Loan that remained outstanding after giving effect to such prepayment was extended, and (c) the Original Agreement was amended in certain other respects. During 1994, the Borrower notified the Agent of (a) the Borrower's receipt of the Tentative Tax Refund (as hereinafter defined) relating to German income taxes for the calendar year 1990 and (b) the Borrower's position that the Tentative Tax Refund did not constitute the Tax Refund for purposes of the First Restated Agreement. In addition, in consideration of the Agent, the Co-Agent and the Banks not challenging that position and in accordance with the terms and provisions of the Tentative Tax Refund Letter (as hereinafter defined), the Borrower agreed to apply the amount of the Tentative Tax Refund as an optional prepayment of the Revolving Portion and, notwithstanding Section 2.04 of the First Restated Agreement, further agreed to not borrow all or any portion of the Tentative Tax Refund Availability Amount (as hereinafter defined) except for the purpose of (i) prior to the Final Determination Date (as defined in the Tentative Tax Refund Letter), repaying amounts constituting the Tentative Tax Refund which the Borrower became obligated to repay to the German tax authorities in respect of German tax assessments or liabilities of the Borrower and certain of its Consolidated Subsidiaries for calendar years 1989 and 1990 or (ii) at the Borrower's election, treating the amount so borrowed as a portion of the Tax Refund and prepaying the Loan pursuant to SECTION 8.01(D) of the First Restated Agreement. During 1994, the Borrower paid DM 175,000,000 to the Agent for application against the Revolving Portion in accordance with the Tentative Tax Refund Letter. On October 31, 1994, the Borrower drew down DM 50,000,000 of the Revolving Portion from the Banks under the Tentative Tax Refund Availability Amount and applied such amount (which constituted part of the Tax Refund) as a prepayment of the Term Portion in accordance with SECTION 8.01(D) of the First Restated Agreement. 2 During 1996, the Borrower notified the Agent of certain proposed transactions involving its Subsidiaries, certain of which transactions were required to be approved by the requisite Banks. As a result, the Second Approval Agreement (as hereinafter defined) was executed and the transactions described in the Second Approval Agreement have been or are in the process of being consummated. On October 22, 1996, the Borrower drew down DM 49,361,653 of the Revolving Portion from the Banks under the Tentative Tax Refund Availability Amount to pay German income taxes in accordance with the Tentative Tax Refund Letter. On January 22, 1997, the Borrower repaid DM 1,649,238 of such amount drawn on October 22, 1996, which DM 1,649,238 amount was applied to the Revolving Portion and thereby increased the Tentative Tax Refund Availability Amount by DM 1,649,238. Immediately prior to the Second Restatement Date, (a) the outstanding principal amount of the Term Portion was DM 395,537,463 and (b) the outstanding principal amount of the Revolving Portion was DM 142,784,415. In addition, immediately prior to the Second Restatement Date, the undrawn portion of the Revolving Portion was DM 107,215,585, DM 77,287,585 of which constituted the Tentative Tax Refund Availability Amount, the reborrowing of which was restricted in accordance with the terms and provisions of the Tentative Tax Refund Letter. Notwithstanding that the Final Determination Date may not have occurred, the Borrower, in consideration of the agreements of the Banks set forth in this Agreement, is willing and desires to treat the amount of DM 77,287,585 as a portion of the Tax Refund as of the Second Restatement Date subject to the terms and conditions of this Agreement. Accordingly, in accordance with SECTION 8.01(D) of the First Restated Agreement and this Agreement, the Borrower shall, on the Second Restatement Date, make a DM 77,287,585 prepayment of the Term Portion, all of which shall be applied, on a pro rata basis as provided in SECTION 8.01(D), to reduce the remaining Repayment Installments of the Term Portion, with the proceeds of a drawdown of the Revolving Portion (in accordance with the Tentative Tax Refund Letter) in the amount of DM 57,287,585 and with DM 20,000,000 of the proceeds of the NL Subordinated Loan referred to in the immediately succeeding paragraph. The Borrower, the Agent and the Banks have discussed, and desire to provide for, (a) a DM 150,000,000 prepayment of the Term Portion of the Loan to be made on the Second Restatement Date from a subordinated loan in the principal amount of DM 260,000,000 to be made by NL Industries to the Borrower and (b) certain other amendments to the First Restated Agreement. DM 20,000,000 of such prepayment will be (as stated in the immediately preceding paragraph) applied, on a pro rata basis, to reduce the remaining Repayment Installments of the Term Portion as a mandatory prepayment of part of the Tax Refund in accordance with SECTION 8.01(D) of the First Restated Agreement and this Agreement and the remaining DM 130,000,000 of such prepayment will be applied as a mandatory prepayment of the Term Portion in accordance with SECTION 8.01(H) of this Agreement and will be applied to the outstanding Repayment 3 Installments of the Term Portion in the direct order of the maturities of such installments. In order to accomplish the foregoing and to address additional matters relating thereto, the Borrower, the Banks and the Agent now desire to amend and restate the First Restated Agreement as provided in this Agreement.

(b) Upon the terms and subject to the conditions set forth in this SECTION 2.04 and elsewhere in this Agreement (including, without limitation, the Borrower's satisfaction of all conditions precedent to such reborrowing), and upon request of the Borrower made pursuant to a Notice of Borrowing delivered to the Agent in compliance with SECTION 4.02(C), each Bank agrees, severally and not jointly, to make advances of the Revolving Portion (including the Kronos Titan Revolving Portion) to or for the account of the Borrower from the First Prepayment Date to August 15, 2000, by making such amounts available to the Agent on the respective Drawdown Dates therefor pursuant to SECTION 11.06; provided, however, that (i) the principal amount of each advance of the Revolving Portion made by each Bank pursuant to this SECTION 2.04 at any time may not exceed such Bank's pro rata share (based upon its Revolving Commitment as a percentage of the aggregate Revolving Commitments of all Banks) of the Revolving Portion Availability at such time and the aggregate principal amount of all advances of the Revolving Portion made by each Bank pursuant to this SECTION 2.04 and outstanding from time to time may not exceed such Bank's pro rata share (based upon its Revolving Commitment as a percentage of the aggregate Revolving Commitments of all Banks) of the Revolving Portion and (ii) the aggregate principal amount of all advances of the Revolving Portion made by all Banks pursuant to this SECTION 2.04 at any time may not exceed the Revolving Portion Availability at such time and the aggregate principal amount of all advances of the Revolving Portion made by all Banks pursuant to this SECTION 2.04 and outstanding from time to time may not exceed the aggregate Revolving Commitments of all Banks. Unless the Agent 42 determines that any applicable condition precedent to any such reborrowing has not been satisfied, the Agent shall make the funds so received from the Banks available to the Borrower pursuant to SECTION 11.05; provided, however, that such funds consisting of drawdowns under the Kronos Titan Revolving Portion requested by Kronos Titan (together with the Borrower) shall be made available directly to Kronos Titan in accordance with SECTION 2.04(C). Each advance of the Revolving Portion made pursuant to this SECTION 2.04 shall be made as a part of a borrowing consisting of advances made by the Banks in accordance with their respective pro rata shares thereof; provided, however, that the failure of any Bank to advance its pro rata share of any such advance shall not in itself relieve any other Bank of its obligation under this SECTION 2.04 (it being agreed, however, that no Bank shall be responsible for the failure of any other Bank to do so). Prior to August 15, 2000, the Borrower may repay and reborrow under this SECTION 2.04 and the Banks shall make advances in accordance with the terms of this Agreement. The Banks shall not be obligated to make any advances of the Revolving Portion under this SECTION 2.04 subsequent to the August 15, 2000. (c) It is acknowledged and agreed by the parties hereto that Kronos Titan may utilize certain proceeds of drawdowns under the Revolving Portion. Accordingly, as of the Second Restatement Date, an amount of the Revolving Portion not to exceed DM 20,000,000 (Deutsche Mark Twenty Million) shall be designated as the "Kronos Titan Revolving Portion". The Kronos Titan Revolving Portion is, and shall be deemed to be for all purposes of this Agreement, a part of the Revolving Portion and is available to be drawn down by the Borrower in accordance with this Agreement. The Borrower and Kronos Titan agree that, notwithstanding anything to the contrary contained in this SECTION 2.04, the Borrower shall use its best efforts to ensure that the proceeds of all drawdowns under the Revolving Portion that are to be utilized by Kronos Titan, unless the Kronos Titan Revolving Portion is then fully drawn, shall be requested by Kronos Titan (together with the Borrower) to be advanced by the Agent directly to Kronos Titan. Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document, each of the Borrower and Kronos Titan hereby jointly and severally agrees to repay the principal of the Kronos Titan Revolving Portion, to pay all interest accrued on such principal that is outstanding from time to time and to pay all fees accrued with respect to the Kronos Titan Revolving Portion from time to time, all in accordance with the terms and provisions of this Agreement; provided, however, that Kronos Titan so agrees only if and to the extent that such indebtedness, liabilities and obligations relate to advances under the Kronos Titan Revolving Portion advanced directly to Kronos Titan. Furthermore, the Borrower acknowledges and agrees that advances of the Kronos Titan Revolving Portion to Kronos Titan shall directly benefit the Borrower to the same extent as if such advances had been made directly to the Borrower, and that the indebtedness, liabilities and obligations of the Borrower with respect to the Kronos Titan Revolving Portion shall be identical to 43 the Borrower's indebtedness, liabilities and obligations with respect to the portion of the Revolving Portion that is not the Kronos Titan Revolving Portion. 2.05 The Borrower may, in connection with and concurrently with any Notice of Borrowing with respect to any reborrowing of the Revolving Portion pursuant to SECTION 2.04 and in connection with and concurrently with any selection of a new Interest Period pursuant to SECTION 5.02, deliver to the Agent a written request that such reborrowing or such portion of the Loan subject to such new Interest Period, as the case may be, be denominated or redenominated (as the case may be) in U.S. Dollars (as opposed to Deutsche Mark), provided, however, that the aggregate principal amount of the Loan at any time outstanding that is denominated in U.S. Dollars may not, without the prior written consent of the Banks that hold at least 80% (eighty percent) of the aggregate unpaid principal amount of the Loans, immediately upon giving effect to any such reborrowing or any such Interest Period, exceed the Base Deutsche Mark Amount of DM 350,000,000 (Deutsche Mark Three Hundred Fifty Million). Each such written request for a U.S. Dollar denominated tranche shall specify the Base Deutsche Mark Amount of such tranche. If such a written request for a U.S. Dollar denominated tranche is not received by the Agent at least five (5) Business Days prior to the proposed Drawdown Date, with respect to a Notice of Borrowing, or no later than 10:00 a.m., Luxembourg time, on the fourth (4th) Business Day prior to the beginning of the relevant Interest Period, with respect to the selection of a new Interest Period, then the tranche shall be denominated in Deutsche Mark, provided, however, that if the corresponding tranche for the Interest Period then ending is denominated in U.S. Dollars, then the tranche for the next succeeding Interest Period shall also be denominated in U.S. Dollars unless the Borrower notifies the Agent, pursuant to SECTION 5.02, that such tranche shall be redenominated in Deutsche Mark for the next succeeding Interest Period. Any agreement or obligation of the Banks to provide any portion of the Loan in Deutsche Mark or U.S. Dollars pursuant to this Agreement shall in all cases be subject to the condition that no circumstance described in SECTION 7.01 shall have occurred (as determined in good faith by the Agent) in the London interbank Euro-currency market or otherwise after request therefor by the Borrower and before the relevant Drawdown Date or the first day of the relevant Interest Period, as the case may be. If the Agent has determined that such a change has occurred, then it shall forthwith give notice thereof to the Borrower and each Bank and the procedures set forth in ARTICLE 7 shall be applicable. 2.06 (a) If the Borrower requests (pursuant to SECTION 2.05) that any reborrowing of the Revolving Portion (pursuant to SECTION 2.04) be denominated in U.S. Dollars, the Banks shall, subject to compliance by the Borrower with SECTION 2.05 and the other terms and conditions of this Agreement, make their advances of the reborrowing in U.S. Dollars in an aggregate amount equal to the Equivalent Amount of the Base Deutsche Mark Amount of the advances to be funded in U.S. Dollars. 44 (b) In the event of any advance of the Loan being redenominated in whole or in part in U.S. Dollars for the next succeeding Interest Period and such advance having been denominated in Deutsche Mark during the Interest Period then ending, each Bank will make an amount equal to the Equivalent Amount in U.S. Dollars of the Base Deutsche Mark Amount of its advance (or the relevant portion thereof) to be denominated in U.S. Dollars during the next succeeding Interest Period available to the Agent on the first day of such next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make each such amount of U.S. Dollars available to the Borrower on such date and in like currency and funds as received by the Agent from the Banks in the manner provided in SECTION 11.06, and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance (or the relevant portion thereof) outstanding in Deutsche Mark during the Interest Period then ending (with accrued interest thereon in Deutsche Mark). (c) In the event that (i) any advance of the Loan denominated in U.S. Dollars is to continue to be denominated in U.S. Dollars for the next succeeding Interest Period, and (ii) as of the last day of the Interest Period then ending, the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars is more than one hundred and five percent (105%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, then the Borrower shall repay to the Agent, on the last day of such Interest Period then ending, an amount of U.S. Dollars as will result in (after giving effect to such repayment) the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, as of the last day of the Interest Period then ending, being equal to one hundred percent (100%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars. The amount to be repaid by the Borrower pursuant to this SECTION 2.06(C) shall be in addition to any Repayment Installment or other amount due and payable by the Borrower on the last day of such Interest Period then ending. In the event that (A) any advance of the Loan denominated in U.S. Dollars is to continue to be denominated in U.S. Dollars for the next succeeding Interest Period, (B) as of the last day of the Interest Period then ending, the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars is less than ninety-five percent (95%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, and (C) no Default shall have occurred and be continuing as of the last day of the Interest Period then ending, then each Bank shall make available to the Agent, and the Agent shall make available to the Borrower, on the last day of such Interest Period then ending, such Bank's pro rata share (based upon its Commitment as a percentage of the aggregate Commitments of all Banks) of an amount of U.S. Dollars as will result in (after giving effect to the delivery of such amount to the Borrower) the aggregate Deutsche Mark 45 Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, as of the last day of the Interest Period then ending, being equal to one hundred percent (100%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars. The obligation of the Banks and the Agent to make such additional amounts available to the Agent and the Borrower, respectively, shall be subject, in all respects, to the condition precedent that no circumstances described in SECTION 7.01, as determined in good faith by the Agent, shall have occurred in the London interbank Euro-currency market or otherwise on or about the last day of such Interest Period then ending. (d) In the event of any advance of the Loan being redenominated in whole or in part in Deutsche Mark for the next succeeding Interest Period and such advance having been denominated in U.S. Dollars during the Interest Period then ending, each Bank will make its advance in Deutsche Mark in an amount equal to such Bank's pro rata share of the Base Deutsche Mark Amount of the aggregate advance to commence on the first day of such next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make each such amount of Deutsche Mark available to the Borrower on such date and in like currency and funds as received by the Agent in the manner provided in SECTION 11.06, and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance (or the relevant portion thereof) outstanding in U.S. Dollars during the Interest Period then ending (with accrued interest therein on U.S. Dollars). (e) In the event that, with respect to any tranche requested to be denominated in U.S. Dollars, any of the events specified in SECTION 7.01 shall occur relating to U.S. Dollar deposits, then the Agent, with the consent of Majority Banks and by the giving of notice to the Borrower, may require that (i) each advance shall be made to the Borrower in Deutsche Mark in an amount equal to such Bank's pro rata share of the Base Deutsche Mark Amount of the aggregate advance requested to be made in U.S. Dollars, (ii) each advance which shall have been denominated in Deutsche Mark during the Interest Period then ending shall continue to be denominated in Deutsche Mark and (iii) each Bank shall make available to the Agent in Deutsche Mark the Base Deutsche Mark Amount of its advance which shall have been outstanding in U.S. Dollars during the Interest Period then ending on the first day of the next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make such Base Deutsche Mark Amount available to the Borrower on the same date and in like currency and funds as received by the Agent from such Bank in the manner provided in SECTION 11.06 and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance denominated in U.S. Dollars during the Interest Period then ending (with accrued interest thereon in U.S. Dollars). 46 (f) In the event the Borrower is required to repay any amounts on the last day of any Interest Period pursuant to this SECTION 2.06, the Agent shall make any amounts to be advanced by the Banks available to the Borrower on the first day of the next succeeding Interest Period only if the Agent receives, concurrently therewith in accordance with this Agreement, the relevant amounts to be repaid by the Borrower pursuant to this SECTION 2.06. The Borrower hereby agrees that it shall indemnify the Agent and each Bank, and hold the Agent and each Bank harmless from and against, any and all funding or foreign exchange costs, losses or expenses that the Agent and the Banks may suffer, sustain or incur as a consequence of a failure by the Borrower to promptly pay, when due, any amounts required to be paid by the Borrower.

Each tranche shall be in a minimum principal amount of DM 100,000,000 (Deutsche Mark One Hundred Million) and integral multiples of DM 10,000,000 (Deutsche Mark Ten Million) in excess thereof (or the Equivalent Amount thereof in U.S. Dollars); provided, however, that any tranche evidencing a reborrowing of the Revolving Portion pursuant to SECTION 2.04 shall be in a minimum principal amount of DM 5,000,000 (Deutsche Mark Five Million) and integral multiples of DM 1,000,000 (Deutsche Mark One Million) in excess thereof (or the Equivalent Amount thereof in U.S. Dollars) and provided, further, however, that any concurrent reborrowing under the Kronos Titan Revolving Portion and reborrowing under the Revolving Portion that does not constitute the Kronos Titan Revolving Portion shall be aggregated for purposes of the immediately preceding proviso. Each tranche shall be denominated in Deutsche Mark or, if permitted by SECTION 2.05 and upon compliance by the Borrower with SECTION 2.05, U.S. Dollars, provided, however, that each tranche shall be entirely denominated in either Deutsche Mark or U.S. Dollars. 5.02 The Borrower shall inform the Agent no later than 10:00 a.m., Luxembourg time, on the 4th (fourth) Business Day prior to the beginning of the relevant Interest Period of the tenor of the next Interest Period, including, without limitation, the duration of such Interest Period and the currency (whether Deutsche Mark or U.S. Dollars) in which the tranche to be outstanding during such Interest Period is to be denominated. Unless the Agent is notified to the contrary by such time, the relevant Interest Period shall have a duration of 52 1 (one) month and the currency in which the tranche to be outstanding during such Interest Period is to be denominated shall be the same currency in which the corresponding tranche was denominated for the Interest Period then ending. 5.03 Each Interest Period for any tranche, other than the initial Interest Period, shall commence on the expiration of the immediately preceding Interest Period for such tranche. If an Interest Period would end on a day which is not a Business Day, such Interest Period shall be extended to the next succeeding Business Day unless such day falls into the next calendar month, in which event such Interest Period shall end on the immediately preceding Business Day. If any other date on which interest is payable under this Agreement is not a Business Day, then payment shall be due on the next succeeding Business Day unless such day falls into the next calendar month, in which event payment shall be due on the immediately preceding Business Day. 5.04 The Borrower may not select an Interest Period which begins prior to a Repayment Date and ends after such Repayment Date unless the aggregate amount of the tranches which have Interest Periods ending on or prior to such Repayment Date shall at least equal the principal amount of the Loan required to be paid on such Repayment Date. Notwithstanding anything herein to the contrary, the Borrower may select an Interest Period other than one, three or six months, but not to exceed six months (subject to the ability of the Reference Banks to determine the Interbank Rate for such period), for that portion of the Loan not in excess of the amount of the Loan which is scheduled to come due pursuant to ARTICLE 9 within six months of the first day of such Interest Period and which Interest Period shall end on such scheduled Repayment Date. ARTICLE 6. INTEREST 6.01 On each Interest Payment Date, the Borrower shall pay to the Agent for the account of the Banks for the Interest Period ending thereon, accrued interest, on the applicable tranche as provided in this Agreement, provided, however, that if any Interest Period is longer than 3 (three) months, accrued interest shall be payable (a) on the date in the third succeeding calendar month numerically corresponding to the commencement date of such Interest Period, or, if there exists no date numerically corresponding to the commencement date of such Interest Period in any such third succeeding month, such accrued interest shall be payable on the last Business Day of such third succeeding calendar month after the first day of such Interest Period and (b) on the Interest Payment Date. Interest shall be paid in the currency in which the applicable tranche is denominated on the applicable Interest Payment Date. 6.02 The rate of interest applicable to each tranche of the Loan during any Interest Period relating thereto shall be the Interbank Rate plus the Margin. 53 6.03 Interest payable pursuant to this Agreement shall be calculated for the actual number of days elapsed on the basis of a 360 (three hundred sixty) day year. 6.04 The Agent shall promptly notify the Borrower and each Bank of each determination of an interest rate made by the Agent under this Agreement. 6.05 All agreements between the Borrower, the Agent and the Banks, whether now existing or hereafter arising and whether written or oral, are hereby limited so that in no contingency, whether by reason of acceleration of the maturity of the Loan or otherwise, shall the interest contracted for, charged or received by the Agent, the Banks or any of them from the Borrower exceed the maximum amount permissible under applicable law. If, from any circumstance whatsoever, interest would otherwise be payable to the Agent, the Banks or any of them in excess of the maximum lawful amount, the interest payable to the Agent, the Banks or any of them shall be reduced to the maximum amount permitted under applicable law; and if from any circumstance the Agent, the Banks or any of them shall ever receive anything of value deemed interest by applicable law in excess of the maximum lawful amount, an amount equal to any excessive interest shall be applied to the reduction of the principal of the Loan and to the payment of interest, or if such excessive interest exceeds the unpaid principal balance of the Loan, such excess shall be refunded to the Borrower. All interest paid or agreed to be paid to the Agent, the Banks or any of them shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full period until payment in full of the principal (including the period of any renewal or extension hereof) so that the interest on the Loan for such full period shall not exceed the maximum amount permitted by applicable law. This paragraph shall control all agreements between the Borrower, the Agent, the Banks or any of them. ARTICLE 7. SUBSTITUTE BASIS 7.01 If any of the following should occur: (a) the Reference Banks determine and notify the Agent that, at or about 11:00 a.m. (London time) on the Interest Determination Date for an Interest Period, no Deutsche Mark deposits (as to the portion of the Loan proposed to be denominated in Deutsche Mark) or no U.S. Dollar deposits (as to the portion of the proposed Loan to be denominated in U.S. Dollars) in the required amount for the required Interest Period are being offered to the Reference Banks by prime banks in the London interbank Euro-currency market; (b) before the close of business in Luxembourg on the Interest Determination Date for an Interest Period, the Majority Banks determine and notify the Agent that the rate at which such deposits were being so offered does not accurately reflect the cost to them of obtaining such deposits; or 54 (c) the Reference Banks shall determine and notify the Agent that, by reason of circumstances affecting the London interbank Euro-currency market generally, such deposits are not available to banks in such market or that adequate and reasonable means do not or will not exist for ascertaining the interest rate applicable to the next succeeding Interest Period; then, notwithstanding the provisions of ARTICLES 5 and 6, the Agent shall forthwith give notice of any such event to the Borrower and each Bank. 7.02 With respect to the circumstances described in SECTIONS 7.01(A) or 7.01(B) above, the Borrower may, subject to the rights of the Agent and the Banks pursuant to SECTION 2.06(E): (a) elect to prepay the applicable portion of the Loan, without premium or penalty, at the end of the then current Interest Period; or (b) select an alternative Interest Period, to the extent available as determined by the Reference Banks 2 (two) Business Days prior to the first day of the next succeeding Interest Period, during which Interest Period the applicable interest rate for the applicable portion of the Loan shall be the Interbank Rate, if available for such alternative Interest Period, plus the applicable Margin; or (c) request that the Agent, on behalf of the Banks, enter into negotiations regarding the applicable interest rate, in which event the Interest Period for the applicable portion of the Loan shall be one month and during such Interest Period the Agent, on behalf of the Banks, and the Borrower shall negotiate in good faith to agree upon an interest rate that will adequately reflect the cost to the Banks of maintaining or funding the applicable portion of the Loan for such Interest Period, and if the Borrower and the Majority Banks (662/3%) are able to agree on such interest rate, the interest rate that shall apply to the applicable portion of the Loan for such Interest Period shall be the sum of the applicable Margin and the interest rate so agreed. If the Borrower and the Agent, on behalf of the Banks, are unable to agree upon an interest rate by the day which is 2 (two) Business Days before the end of the one-month Interest Period referred to above, the interest rate that shall apply to the Loan for such Interest Period shall be (i) the rate determined by the Agent to be the arithmetic mean (rounded upwards, if necessary, to the nearest four decimal places) per annum of the respective rates notified to the Agent by each Reference Bank as that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower, plus (ii) the applicable Margin. 55 7.03 With respect to circumstances described in SECTION 7.01(C) above, the duration of such next succeeding Interest Period shall be one month or, if the period until the next Repayment Date is less than one month, shall end on the next Repayment Date and, during such Interest Period, the Borrower and the Agent, on behalf of the Banks and subject to the consent of the Majority Banks (662/3%), shall negotiate in good faith in order to redenominate the applicable portion of the Loan in an alternative currency which is freely convertible into Deutsche Mark (which alternative currency may include, without limitation, Deutsche Mark as to the portion of the Loan proposed to be denominated in U.S. Dollars) and in which deposits are available to the Reference Banks for determining the interest rate from time to time applicable thereto (but excluding any such currency for which any central bank or other governmental authorization in the country of issue is required to permit use of such currency by a Bank for lending hereunder, if such authori zation has not been obtained and any currency the use of which as contemplated hereunder is restricted or prohibited pursuant to any request, directive, regulation or guideline of any governmental authority (whether or not having the force of law) with which any Bank is accustomed to act), and the interest rate that shall apply to the applicable portion of the Loan for such Interest Period shall be the sum of the applicable Margin and the interest rate for the alternative currency so agreed. If the Borrower and the Agent, on behalf of the Banks and with the consent of the Majority Banks (662/3%), are unable to agree on such alternative currency or an interest rate for such alternative currency by the day which is 2 (two) Business Days before the end of the Interest Period referred to above, the Borrower shall repay the applicable portion of the Loan together with accrued interest thereon at the rate determined by the Agent to be the arithmetic mean (rounded upwards, if necessary to the nearest four decimal places) of the respective rates notified to the Agent by each Reference Bank as being that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower, plus the applicable Margin, on the next Interest Payment Date, without premium or penalty except as otherwise provided in SECTION 12.04. 7.04 During the period when any alternative interest rate or Interest Period or redenomination of the Loan or any applicable portion thereof is in force pursuant to SECTION 7.02 or 7.03 above, the Agent, in consultation with the Banks, shall periodically review whether circumstances are such that an Interbank Rate may again be determined in accordance with ARTICLES 5 and 6. If such a determination may again be made, the Agent shall forthwith give written notice thereof to the Borrower and each Bank and the Interbank Rate, plus the applicable Margin, shall be the applicable interest rate commencing with the beginning of the next Interest Period for the Loan or the applicable portion thereof. ARTICLE 8. PREPAYMENT 8.01 From and after the Prepayment Date, the Borrower shall make mandatory prepayments of the Loan as follows: 56 (a) An amount equal to the Net Proceeds (with respect to CLAUSES (2) and (3) below, only to the extent that the aggregate Net Proceeds exceed DM 15,000,000 (Deutsche Mark Fifteen Million) during any calendar year, from: (1) the Disposition by the Borrower or any of its Subsidiaries of any Stock of any Subsidiary, other than: (i) Dispositions of Stock of any of the Subsidiaries from the Borrower to any Subsidiary, from a Subsidiary to the Borrower, or between Subsidiaries; or (ii) Dispositions which constitute Restricted Payments permitted in accordance with SECTION 16.20 or Dispositions permitted in accordance with SECTION 16.15(C); (2) the Disposition by the Borrower or any of its Subsidiaries of any assets, individually or in the aggregate, or of any Stock of any Subsidiary (other than a Major Subsidiary or a Pledged Subsidiary), other than: (i) Dispositions of assets in the ordinary course of business; (ii) Dispositions from the Borrower to any Subsidiary, from a Subsidiary to the Borrower or between Subsidiaries; (iii) Dispositions which constitute Restricted Payments permitted in accordance with SECTION 16.20 or Dispositions permitted in accordance with SECTION 16.15(C); (iv) Dispositions which constitute interest payments on Subordinated Debt permitted in accordance with SECTION 16.09(D); (v) Dispositions or other events described in CLAUSES (1) or (3) of SECTION 8.01(A); or (vi) Dispositions prior to the Second Restatement Date of the distributorship/marketing arrangements existing as of the First Restatement Date between Rheox, Inc. and/or its subsidiaries and certain Subsidiaries of the Borrower; and/or (3) the Disposition, termination, shortening or other modification of the Leverkusen Lease or any agreement providing for the Disposition, termination, shortening or other modification of the Leverkusen Lease; 57 shall be used, to the extent permitted by law, to prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, on the Interest Payment Date(s) immediately following the receipt by the Borrower or any Subsidiary of such Net Proceeds, in accordance with SECTION 8.01(B). If the Net Proceeds from the aforementioned Dispositions described in CLAUSES (2) or (3) of this SECTION 8.01(A) or from other transactions described in CLAUSE (3) of this SECTION 8.01(A) exceed DM 15,000,000 (Deutsche Mark Fifteen Million) in any calendar year, or, if there are any Net Proceeds from the aforementioned Dispositions described in CLAUSE (1) of this SECTION 8.01(A), then the Borrower shall in accordance with SECTION 8.01(B) make a mandatory prepayment in cash equal to the amount of such excess in the case of CLAUSES (2) and (3) or equal to the amount of such Net Proceeds in the case of CLAUSE (1), in each case whether or not the Net Proceeds are comprised of cash or non-cash proceeds. For purposes of this SECTION 8.01(A), the value of the non-cash proceeds received shall be determined in good faith by the chief financial officer of the Borrower. (b) Amounts payable under SECTION 8.01(A) shall be deposited promptly into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit with the Agent until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied at the Borrower's request to interest or, on a pro-rata basis, to reduce the remaining Repayment Installments of the Term Portion or, after such installments are paid in full, to permanently reduce the Revolving Portion. (c) On the Interest Payment Date(s) immediately following delivery of the financial statements in accordance with SECTION 16.01(A), the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to 70% (seventy percent) of the amount by which Excess Cash Flow for the immediately preceding fiscal year exceeds DM 20,000,000 (Deutsche Mark Twenty Million); provided, however, that this sentence shall apply only to Excess Cash Flow for fiscal year 1996 and fiscal years prior thereto. On the earlier to occur of (a) 5 (five) days after the date upon which EBITDA for the immediately preceding fiscal year (commencing with the fiscal year 1997) has been finally determined or (b) 90 (ninety) days after the immediately preceding fiscal year end, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to 70% (seventy percent) of Excess EBITDA for the immediately preceding fiscal year. In addition, on or before March 31, 1997, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to the amount (if any) by which EBITDA of NL Industries and its subsidiaries for fiscal year 1996 exceeds $140,000,000 (One Hundred Forty Million Dollars). All such prepayments shall be applied to the Repayment Installments of the Term Portion in the inverse order 58 of the maturities of such installments or, after such installments are paid in full, to permanently reduce the Revolving Portion. (d) An amount equal to the amount of each payment received by the Borrower with respect to the Tax Refund at any time shall be used by the Borrower to prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, on the Interest Payment Date(s) immediately following the date(s) upon which such payment(s) is (are) received by the Borrower. Amounts payable under this SECTION 8.01(D) shall be deposited promptly into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied, on a pro-rata basis, to reduce the remaining Repayment Installments of the Term Portion or, after such installments are paid in full, to permanently reduce the Revolving Portion. The Borrower represents and warrants to the Agent and the Banks that all amounts drawn under the Tentative Tax Refund Availability Amount prior to the Second Restatement Date have been used to pay German income taxes or have been paid to the Agent and applied to reduce the Revolving Portion in accordance with paragraph 2 of the Tentative Tax Refund Letter. Accordingly, the Borrower, the Agent and the Banks hereby agree that (although the Final Determination Date may not yet have occurred) DM 77,287,585 (Deutsche Mark Seventy-Seven Million Two Hundred Eighty-Seven Thousand Five Hundred Eighty-Five) shall be deemed to be the remaining amount of the Tax Refund received by the Borrower as of the Second Restatement Date and not previously applied to prepay the Term Portion and that, on the Second Restatement Date, DM 57,287,585 (Deutsche Mark Fifty-Seven Million Two Hundred Eighty-Seven Thousand Five Hundred Eighty-Five) of the Tax Refund shall be drawn under the Tentative Tax Refund Availability Amount of the Revolving Portion Availability and applied to the Term Portion in accordance with this SECTION 8.01(D) and DM 20,000,000 (Deutsche Mark Twenty Million) of the proceeds of the Second Prepayment shall be applied to the Term Portion in accordance with this SECTION 8.01(D). As of the Second Restatement Date, DM 20,000,000 (Deutsche Mark Twenty Million) of the Tentative Tax Refund Availability Amount shall be deemed to have been cancelled by virtue of the reduction in the maximum principal amount of the Revolving Portion from DM 250,000,000 (Deutsche Mark Two Hundred Fifty Million) to DM 230,000,000 (Deutsche Mark Two Hundred Thirty Million). (e) On March 15, 2000, the Borrower shall prepay, and permanently reduce, the Revolving Portion in an amount equal to the positive remainder (if any) of (i) the then outstanding principal amount of the Revolving Portion minus (ii) DM 125,000,000 (Deutsche Mark One Hundred Twenty-Five Million). 59 (f) Upon the occurrence of a "Change of Control", as such term is defined in either of the Indentures, the Borrower shall promptly so notify the Agent and each of the Banks of such occurrence and shall (whether or not the Borrower complies with its obligation to give such notice) prepay the Loans, and all accrued and unpaid interest thereon to the date of the prepayment, in full on the date upon which the holders of any of the NL Notes may receive prepayment of any of the NL Notes as a result of such Change of Control (assuming such holders elect to receive such prepayment but whether or not such holders so elect) unless the Majority Banks (662/3%) shall have expressly waived such right of prepayment on or before the date upon which such prepayment is required to be made. (g) On or before 2 (two) Business Days after the last day of each calendar month upon which the aggregate cash balances of the Borrower and its Subsidiaries (excluding any cash balances of the Borrower and its Canadian Subsidiaries which are pledged to the Agent as security for the Loans and excluding U.S. Dollar cash balances held in the ordinary course of business) exceed DM 40,000,000 (Deutsche Mark Forty Million) (or the equivalent amount in any currency), the Borrower shall prepay, without premium or penalty except as set forth in SECTION 12.04, the outstanding principal amount of the Revolving Portion by the entire amount of such excess; provided, however, that the cash balances held by the Borrower immediately prior to a Repayment Date or a date upon which payments are required to be made on the Mirror Notes which are to be applied and are actually applied to make repayments of the Loan or such required payments on the Mirror Notes, respectively, shall be excluded for purposes of determining the cash balances of the Borrower and its Subsidiaries pursuant to this SECTION 8.01(G). For purposes of this SECTION 8.01(G) and SECTION 16.40, "cash balances" shall mean the aggregate of the collected cash balance in bank accounts (net of checks issued and uncleared), other cash (exclusive of petty cash maintained in reasonable amounts in the ordinary course of business) and Temporary Cash Investments. Amounts payable under this SECTION 8.01(G) shall be deposited, within such 2 (two) Business Days, into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit with the Agent until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied to the Revolving Portion as provided herein. The Borrower covenants and agrees that it will not, and will not permit any of its Subsidiaries to, convert non-U.S. Dollar cash balances to U.S. Dollar cash balances except to the extent reasonably necessary in the ordinary conduct of their business. (h) On the Second Restatement Date, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in the amount of DM 130,000,000 (Deutsche Mark One Hundred Thirty Million). Such prepayment 60 shall be applied to the Repayment Installments of the Term Portion in the direct order of the maturities of such installments. 8.02 The Borrower may make optional prepayments (including the portion of the First Prepayment applied toward the Revolving Portion pursuant to SECTION 2.01(A) and optional prepayments deemed made with funds provided by NL Industries and/or Kronos resulting from capital contributions made or Subordinated Debt, other than the Kronos Subordinated Loan and the NL Subordinated Loan, extended by NL Industries and/or Kronos to the Borrower) as follows: On giving not less than 5 (five) days prior written notice to the Agent, the Borrower may prepay all or any part (but in any case not less than DM 5,000,000 (Deutsche Mark Five Million) (or the Equivalent Amount thereof in U.S. Dollars) and in integral multiples of DM 1,000,000 (Deutsche Mark One Million) (or the Equivalent Amount thereof in U.S. Dollars) in excess thereof per prepayment) of the Loan on any Interest Payment Dates, without premium or penalty, except as otherwise provided in SECTION 12.04, provided that: (a) except as expressly permitted by SECTION 2.04 with respect to the Revolving Portion, each prepayment made under this Agreement may not be reborrowed under this Agreement; (b) unless the Borrower expressly informs the Agent, in connection with the aforesaid notice of such prepayment, that such prepayment shall be applied to the Revolving Portion, any prepayment under this SECTION 8.02 shall be applied to the outstanding Repayment Installments of the Term Portion in inverse order of the maturities of such installments; and (c) notice of prepayment given by the Borrower shall be irrevocable and the Borrower shall be bound to prepay in accordance with each such notice. 8.03 To the extent that the amounts available to prepay the Loan pursuant to SECTIONS 8.01 or 8.02 shall exceed the principal of the tranche relating to the immediately following Interest Payment Date, such amounts shall be applied to prepay the principal of such tranche and the remainder, if any, shall be applied to prepay the principal of the tranche relating to the next immediately following Interest Payment Date or Dates, as the case may be, until all amounts allocated for prepayment have been applied. The requirement that prepayments be applied pro rata under SECTION 8.01(B) or 8.01(D), in inverse order of maturity under SECTION 8.01(C) and SECTION 8.02 or in direct order of maturity under SECTION 8.01(H) shall not be affected by the fact that prepayments may be made on an Interest Payment Date which is also a Repayment Date. 61 ARTICLE 9. REPAYMENT Subject to the prepayment provisions set forth in ARTICLE 8, the Term Portion shall be repaid in 6 (six) installments due and payable on each of the following Repayment Dates in the following amounts: REPAYMENT DATE REPAYMENT INSTALLMENT March 15, 1997 DM 50,000,000 September 15, 1997 DM 50,000,000 March 15, 1998 DM 75,000,000 September 15, 1998 DM 75,000,000 March 15, 1999 DM 100,000,000 minus 50% (fifty percent) of the Excess Term Prepayment (if any) September 15, 1999 DM 100,000,000 minus 50% (fifty percent) of the Excess Term Prepayment (if any) Subject to the prepayment provisions set forth in ARTICLE 8, the Revolving Portion (which shall be reduced to DM 105,000,000 (Deutsche Mark One Hundred Five Million) on March 15, 2000) shall be repaid (as provided in SECTION 8.01(E)) on March 15, 2000 to the extent necessary to cause the outstanding principal amount of the Revolving Portion, after giving effect to such repayment, to equal DM 105,000,000 (Deutsche Mark One Hundred Five Million), and shall be repaid in full on September 15, 2000. All amounts owed under this Agreement with respect to the Term Portion shall be due and payable on or before September 15, 1999, in accordance with the terms of this Agreement, and all amounts owed under this Agreement with respect to the Revolving Portion shall be due and payable on or before September 15, 2000, in accordance with the terms of this Agreement. After giving effect to the mandatory prepayments to be made on the Second Restatement Date pursuant to SECTIONS 8.01(D) and 8.10(H) (including the Second Prepayment), (a) the Repayment Installments of the Term Portion previously (immediately prior to the Second Amendment Date) due on each of March 15, 1997, September 15, 1997, and March 15, 1998 shall have been paid in full and (b) the Repayment Installments of the Term Portion previously (immediately prior to the Second Amendment Date) due on each of September 15, 1998, March 15, 1999, and September 15, 1999, shall have been paid in part. Accordingly, after giving effect to such prepayments, the remaining outstanding Term Portion shall be payable in 3 (three) installments due and payable on the following Repayment Dates in the following amounts: 62 REPAYMENT DATE REMAINING REPAYMENT INSTALLMENT September 15, 1998 DM 48,751,048 March 15, 1999 DM 70,785,415 September 15, 1999 DM 68,713,415 ARTICLE 10. EVIDENCE OF DEBT 10.01 Each Bank shall maintain, in accordance with its usual practice, accounts evidencing the amounts from time to time lent by and owing to it under this Agreement, including such amounts with respect to each of the Term Portion and the Revolving Portion, which accounts shall be prima facie evidence of such amounts. Such amounts shall be designated in Deutsche Mark or U.S. Dollars, as appropriate, and, if designated in U.S. Dollars, shall also be designated in the corresponding Base Deutsche Mark Amount. 10.02 The Agent shall maintain on its books an account in which shall be recorded: (a) the amount of the Loan (and the currency in which each portion of the Loan is denominated or redenominated from time to time), including the amount of each of the Term Portion and the Revolving Portion outstanding from time to time, and each Bank's share therein; (b) the amount of any principal or interest due or to become due from the Borrower to the Banks under this Agreement (and the currency in which such amount is denominated or redenominated from time to time) with respect to each of the Term Portion and the Revolving Portion and each Bank's share therein; and (c) the amount of any sum received or recovered by the Agent (and the currency in which such amount is denominated) under this Agreement and each Bank's share therein. 10.03 In any legal action or proceeding arising out of or in connection with this Agreement, the entries made in the accounts maintained pursuant to SECTIONS 10.01 and 10.02 shall be prima facie evidence of the existence and amounts of the obligations and the payments of the Borrower therein recorded. In the case of any conflict between accounting under SECTION 10.01 and 10.02, the accounts of each Bank under SECTION 10.01 shall control. ARTICLE 11. PAYMENTS 11.01 Any and all payments by the Borrower and/or Kronos Titan under this Agreement shall be made without setoff or counterclaim, and free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, whether under U.S. or German law or otherwise, 63 excluding, in the case of each Bank and the Agent, taxes imposed on its overall net income and franchise taxes imposed on it by the jurisdiction under the laws of which such Bank or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its overall net income and franchise taxes imposed on it by the jurisdiction of such Bank's Lending Office or any political subdivision thereof (all such excluded taxes being hereunder referred to as "Excluded Taxes" and all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower and/or Kronos Titan shall be required by law (whether U.S. or German or otherwise) to deduct any Taxes from or in respect of any sum payable hereunder to any Bank or the Agent, (a) and if the deductions are the result of a change in circumstances after May 30, 1990 of the type described in CLAUSE (1) of SECTION 14.01(A), the sum payable shall be increased as may be necessary so that, after making all required deductions, such Bank or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (b) the Borrower and/or Kronos Titan shall make such deductions; and (c) the Borrower and/or Kronos Titan shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. Any Bank claiming any additional amounts payable pursuant to this SECTION 11.01 shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to transfer its portion of the Loan to a Lending Office in another jurisdiction where no such deductions are required. The Borrower and/or Kronos Titan shall forward promptly to the Agent official receipts of the relevant taxation or other authority or other evidence acceptable to the respective recipient of the amount deducted or withheld as described above, when and as such receipts or other evidence are made available to the Borrower and/or Kronos Titan by the relevant authority. 11.02 From time to time upon the request of the Borrower, Kronos Titan or the Agent, (a) each Bank organized under the laws of a jurisdiction outside the United States shall provide the Agent and the Borrower and/or Kronos Titan with a certificate, signed by an officer of each such Bank, stating that payments to be made to such Bank hereunder are expected, in the reasonable judgment of such Bank, to be exempt from United States withholding tax, if such Bank is so exempt, and the forms (if any) prescribed by the Internal Revenue Service of the United States certifying as to such Bank's status; and (b) each Bank organized under the laws of a jurisdiction outside Germany shall provide the Agent and the Borrower and/or Kronos Titan with a certificate, signed by an 64 officer of each such Bank, stating that payments to be made to such Bank hereunder are expected, in the reasonable judgment of such Bank, to be exempt from German withholding tax, if such Bank is so exempt, and the forms (if any) prescribed by the appropriate German governmental tax authority certifying as to such Bank's status. Unless the Borrower, Kronos Titan or the Agent (as applicable) has received forms or other documents satisfactory to it indicating that payments hereunder are not subject to United States or German withholding tax, as applicable, the Borrower, Kronos Titan or the Agent (as applicable) shall, unless the Borrower, Kronos Titan or the Agent (as applicable) determines that no such withholding is required, withhold taxes from such payments at the applicable statutory rate in the case of payments to or for any Bank organized under the laws of a jurisdiction outside the United States or the Federal Republic of Germany, as the case may be. If any Bank fails to furnish to the Borrower, Kronos Titan or the Agent (as applicable) forms or other documents necessary for claiming exemption from United States or German withholding tax, then payments to such Bank shall be net of any amounts the Borrower, Kronos Titan or the Agent (as applicable) is required to withhold under applicable law, provided, however, that, notwithstanding anything in this Agreement to the contrary, any Bank that is subject to withholding as a result of a change in circumstances occurring after May 30, 1990 of the type described in SECTION 14.01 shall be entitled to payments pursuant to SECTION 11.01(A). Each Bank hereby represents and warrants to the Borrower and Kronos Titan that, on the date that it became or becomes a Bank in accordance with the terms of the Original Agreement, the First Restated Agreement or this Agreement, respectively (as may be applicable), its Lending Office was or is entitled to receive payments of principal of, and interest on, Loans made by such Bank from such Lending Office without withholding or deduction for or on account of Taxes imposed by the United States of America, Germany or any respective political subdivisions of the United States of America or Germany. 11.03 If the Borrower and/or Kronos Titan makes an increased payment to any Bank pursuant to SECTION 11.01 and such Bank determines in its reasonable discretion that it has received or been granted a credit against or relief or remission for, or payment of tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such payment, such Bank shall, to the extent that it can in its sole discretion do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower and/or Kronos Titan (as applicable) such amount as such Bank shall have calculated to be attributable to such deduction or withholding. If Taxes are incorrectly or illegally paid or assessed, and if any Bank or the Agent contests the payment or assessment of such Taxes, such Bank or the Agent shall refund, to the extent of any refund made to such Bank or the Agent, any amounts paid by the Borrower and/or Kronos Titan under SECTION 11.01 in respect of such Taxes. Amounts payable pursuant 65 to this SECTION 11.03 shall be paid within 30 (thirty) days from the date of receipt of the relevant refund by such Bank or the Agent (as the case may be). 11.04 All payments to be made by the Borrower and/or Kronos Titan under this Agreement shall be made in the appropriate currency (Deutsche Mark or U.S. Dollars, as applicable) and in immediately available funds not later than 10:00 a.m. (local time at Munich) on the date upon which the relevant payment is due, (a) with respect to payments in Deutsche Mark, to the Agent's account no. 6450025141 with Bayerische Hypotheken-und Wechselbank AG, Munich, or (b) with respect to payments in U.S. Dollars, to the Agent's account no. 001 1 329 026 with The Chase Manhattan Bank N.A., New York, or (in either case) to such other bank and account as the Agent may from time to time designate by written notice to the Borrower and/or Kronos Titan (as applicable). All payments (including prepayments) of principal or interest accrued with respect to the Revolving Portion of the Loans shall be applied (i) first, to the payment of interest accrued with respect to the Revolving Portion other than the Kronos Titan Revolving Portion (until such interest is paid in full), (ii) second, to the payment of the outstanding principal amount of the Revolving Portion other than the Kronos Titan Revolving Portion (until such principal is paid in full), (iii) third, to the payment of interest accrued with respect to the Kronos Titan Revolving Portion (until such interest is paid in full), and (iv) fourth, to the payment of the outstanding principal of the Kronos Titan Revolving Portion (until such principal is paid in full). 11.05 All payments to be made by the Agent to the Borrower (or, with respect to advances under the Kronos Titan Revolving Portion, Kronos Titan) under this Agreement shall be made not later than 10:00 a.m. (local time at Munich) on the date upon which the relevant payment is due and, at the risk of the Borrower (and, with respect to advances under the Kronos Titan Revolving Portion, Kronos Titan), remitted to, in the case of the Borrower, an account in Munich or Luxembourg maintained at Hypobank International S.A. or an affiliate of Hypobank International S.A. which is pledged to secure the Loans in accordance with SECTION 16.40 or, in the case of Kronos Titan, an account of Kronos Titan. 11.06 Each Bank shall make available to the Agent in the appropriate currency (Deutsche Mark or U.S. Dollars, as the case may be) as the Agent may from time to time designate its portion of the Loan hereunder prior to 10:00 a.m. (local time at Munich) on the Drawdown Date or, with respect to any redenomination of any advance pursuant to SECTION 2.06, on the first day of the next succeeding Interest Period, as the case may be, to such account as the Agent may from time to time designate for the account of the Borrower and/or Kronos Titan (as applicable). Not less than 2 (two) Business Days prior to the effective date of any initial advance of the Loan in U.S. Dollars, each Bank shall notify the Agent of the identity and location of the Lending Office for such Bank in relation to all advances and payments to be denominated in U.S. Dollars in the event that such Lending Office is different from the Lending Office previously designated for the 66 Loan, provided, however, that (a) each Bank shall utilize the Lending Office previously designated for the Loan unless it is prohibited from doing so by applicable regulatory requirements, (b) if the use of such previously designated Lending Office is so prohibited, such Bank shall use its best efforts to use a Lending Office entitled to an exemption from United States and German withholding taxes (but no Bank shall be required to establish an office or branch or obtain any authorization to engage in banking activities in any jurisdiction in order to be entitled to any exemption from United States withholding taxes), and (c) such Bank shall give written notice to the Borrower and/or Kronos Titan (as applicable) if it is unable to utilize its Lending Office previously designated for the Loan and if its Lending Office utilized for the Loan is not entitled to an exemption from U.S. and German withholding taxes, and further provided that the Borrower shall not be in any way relieved of any obligation to gross up any payments to be made to the Agent or any Bank under this Agreement. All advances to be made by each Bank in U.S. Dollars shall be made available through the Lending Office of such Bank so designated for advances in U.S. Dollars. 11.07 Except for payments received by the Agent for its account or for the account of a specific Bank in accordance with this Agreement, the Agent shall promptly distribute in like funds and currency each payment received by it for the account of the Banks ratably in proportion to their portion of the Loan or, as the case may be, their respective Commitments. 11.08 Where an amount is to be made available under this Agreement by the Agent to a Person, the Agent shall not be bound to make such amount available to such Person until the Agent has been able to establish whether or not such amount has been made available to the Agent. If the Agent makes an amount available to the Borrower and/or Kronos Titan which has not, but should have, been made available to the Agent by a Bank, the Borrower and/or Kronos Titan (as applicable) shall (without prejudice to any rights the Borrower and/or Kronos Titan (as applicable) may have against that Bank) refund that amount to the Agent on request. If the Agent makes an amount available to a Bank which has not, but should have, been made available to the Agent by the Borrower and/or Kronos Titan, that Bank shall (without prejudice to any rights it may have against the Borrower and/or Kronos Titan, as applicable) refund that amount to the Agent on a date to be determined by the Agent after consultation with such Bank. Where, in accordance with the foregoing, an amount is to be refunded to the Agent, the Agent in addition shall be indemnified by the Person who has failed to make an amount available as required under this Agreement against any reasonable interest costs actually incurred and paid by the Agent by reason of any lapse of time between the date on which the amount was made available to any Person by the Agent and the date on which the amount was refunded to the Agent in full (including, without limitation, any interest paid by the Agent in respect of funds borrowed by the Agent in order to fund such amount during such period). 11.09 Any currency specified in accordance with this Agreement shall be the currency of account and of payment in all events. The payment obligations of the Borrower and Kronos Titan hereunder shall not be discharged by an amount paid in another currency, whether 67 pursuant to a judgment or otherwise, to the extent that the amount so paid upon conversion by the Agent or the Banks (as applicable) to the specified currency under normal and reasonable banking procedures does not yield at the place when payment is due the amount of the specified currency due hereunder. In the event that any payment by or on behalf of the Borrower and/or Kronos Titan, whether pursuant to a judgment or otherwise, upon such conversion and after the deduction of all fees, costs and expenses relating thereto does not result in payment of such amount of the specified currency at the place payment is due, the Agent and each Bank shall be entitled to receive from the Borrower and/or Kronos Titan (as applicable), and shall have a separate cause of action for, the deficiency in respect of the payments due to each, respectively. ARTICLE 12. DEFAULT INTEREST AND INDEMNITY 12.01 In the event of a failure by the Borrower to pay any sum on the date on which such sum is due and payable pursuant to this Agreement and irrespective of any notice by the Agent or any other Person to the Borrower in respect of such failure, the Borrower shall pay interest on such sum, on demand, from the date of such failure up to the date of actual payment (both after and before any judgment) at the rate, increased by the sum of the Margin plus 2% (two percent), determined by the Agent to be the arithmetic mean (rounded upwards, if necessary, to the nearest four decimal places) of the rates notified to the Agent by the Reference Banks to be those at which deposits in Deutsche Mark or U.S. Dollars as the Agent may select in its discretion (after consultation with the Banks) for such period as the Agent may select in its discretion (after consultation with the Banks) are so offered to each Reference Bank by prime banks in the London interbank Euro-currency market at or about 11:00 a.m. (London time) for value 2 (two) Business Days after the Business Day immediately succeeding that on which the Agent becomes aware of such failure and, so long as the failure continues, such rate shall be recalculated on the same basis thereafter, provided that: (a) if any Reference Bank is unable or otherwise fails to furnish a quotation for the purposes of this SECTION 12.01, the interest rate shall be determined on the basis of the quotation(s) furnished by the remaining Reference Bank(s); and (b) if for any such period, none of the Reference Banks was offered deposits in the required amount and for the required period, the rate of interest applicable thereto shall be the weighted average (having regard to the respective portions of such unpaid sum) (rounded upwards, if necessary to the nearest four decimal places) per annum of the respective rates notified to the Agent by each Reference Bank as being that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower. Interest accruing under this SECTION 12.01 shall be due and payable at the end of each period by reference to which it is calculated. 68 12.02 Without prejudice to the foregoing and irrespective of any notice by the Agent or any other Person to the Borrower in respect of the Borrower's failure to make any payment when due or in respect of any other matter relating to this SECTION 12.02, the Borrower shall indemnify the Agent and the Banks against any and all damages, losses or expenses (including, without limitation, losses incurred in paying default interest or in liquidating or employing deposits from third parties acquired to make, fund or maintain the Loan or any part thereof, including interest and penalties on unpaid Taxes, if any, and including losses on foreign currency exchanges, if any, with respect to portions of the Loan denominated in U.S. Dollars) which any of them may properly and reasonably sustain or incur as a consequence of (a) the failure by the Borrower to borrow pursuant to any Notice of Borrowing, (b) the failure by the Borrower to pay any sum, including Taxes, if any, when due and payable under this Agreement upon the occurrence of any Event of Default, (c) the funding of the Loan or any portion thereof in U.S. Dollars as opposed to Deutsche Mark or (d) the liquidation or employment of amounts borrowed or contracted for relating to, or the termination or unwinding of any contract entered into in order to fund, an advance in U.S. Dollars requested by the Borrower that, by reason of the occurrence of any event specified in SECTION 7.01, is not funded as requested. 12.03 If for the purposes of filing a claim or proof for obtaining or enforcing any judgment in any court, it is necessary to convert a sum due under this Agreement in Deutsche Mark or U.S. Dollars (as the case may be) (the "Original Currency") into another currency (the "Other Currency"), the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate of exchange offered by any one or more of the Reference Banks to the Agent, in respect of the relevant sums, at which, in accordance with normal banking procedures, the Agent could purchase the greatest amount of the Original Currency with the Other Currency at or about 11:00 a.m. in London on the Business Day preceding that on which final judgment is given. The obligation of the Borrower in respect of any sum due in the Original Currency from it to any Bank or the Agent under this Agreement shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by such Bank or the Agent (as the case may be) of any sum adjudged to be so due in such Other Currency, such Bank or the Agent (as the case may be) may in accordance with normal banking procedures purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to such Bank or the Agent (as the case may be) in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify immediately such Bank or the Agent (as the case may be) against such loss, and if the amount of the Original Currency so purchased exceeds the sum originally due to any Bank or the Agent (as the case may be) in the Original Currency, such Bank or the Agent (as the case may be) agrees to remit to the Borrower such excess. The above indemnity shall constitute a separate and independent obligation of the Borrower from its other obligations under this Agreement and shall apply irrespective of any grace period granted by the Agent or the Banks. 69 12.04 Any prepayment or repayment of principal made under this Agreement, if made otherwise than on an Interest Payment Date relative to the amounts prepaid or repaid, shall be made together with accrued interest thereon and such additional amount as each Bank may certify as necessary to compensate it for any damages or losses incurred or to be incurred by it in connection with such prepayment or repayment (including loss of Margin and losses on account of funds borrowed in order to make, fund or maintain its proportion of the Loan or any part thereof prepaid or repaid). ARTICLE 13. SET-OFF AND REDISTRIBUTION OF PAYMENTS 13.01 Upon the occurrence and during the continuance of any Event of Default specified in SECTION 18.01 consisting of the failure to pay principal of the Loan or any portion thereof and subject to the prior written consent of the Agent or the Majority Banks or upon the occurrence and during the continuance of any Event of Default and the acceleration of the maturity of the Loan pursuant to the provisions of ARTICLE 18, each Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (at any office or branch) to or for the credit or the account of the Borrower against all or any portion of the Loan outstanding under this Agreement and other amounts payable hereunder. Each Bank agrees promptly to notify the Borrower after any such set-off and application made by such Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this ARTICLE 13 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Bank may have. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any portion of the Loan held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any portion of the Loan held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participation in the portion of the Loan held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loans held by the Banks shall be shared by the Banks pro rata; provided that nothing in this ARTICLE 13 shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness hereunder. Subject to SECTION 13.02 hereof, the Borrower agrees, to the fullest extent such holder may effectively do so under applicable law, that any holder of a participation in a Loan, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. Anything herein to the contrary notwithstanding, nothing in this ARTICLE 13 shall impair the right of the Borrower to receive notice and to have the opportunity to cure certain Events of Default as provided in ARTICLE 18 or otherwise prior to the declaration of an acceleration of maturity. 70 13.02 Except for payments to a Bank from the Agent which were received by the Agent for the account of such Bank in accordance with the provisions of this Agreement, if any Bank shall at any time receive payment or satisfaction of all or a part of its share of the Loan, interest thereon or any other amount payable hereunder, whether by setoff, counterclaim or otherwise, in a proportion which, in relation to any amounts received by any other Bank or Banks at the same time, represents more than its percentage participation in the Loan, then such Bank shall notify the Agent thereof and shall pay to the Agent not later than 10 (ten) days after request by the Agent for account of the other Banks such amount as determined by the Agent as will ensure that each Bank will receive a proportion of such payment equal to its percentage participation. 13.03 In the event that at any time any Bank shall be required to refund to the Borrower any amount which has been paid to or received by it by set-off, counterclaim or otherwise on account of any part of the Loan, interest thereon or any other amount payable hereunder and which has been paid to any other Bank pursuant to this ARTICLE 13, such other Bank shall repay a proportionate amount of the amounts so refunded without interest. 13.04 The Borrower and the Banks expressly agree that payments by or recoveries from the Borrower shall be distributed in accordance with the provisions of this ARTICLE 13 without the need for further consent or the completion of any other formalities whatsoever. 13.05 If a Bank is required to make any payment to any other Bank pursuant to this ARTICLE 13, then, subject to SECTION 13.02, the liability of the Borrower to the Bank making such payment under this Agreement shall be treated as not having been reduced by the amount of such payment and the liability of the Borrower to any Bank receiving such payment shall be treated as having been reduced by the amount of the payment received by such Bank. ARTICLE 14. CHANGE OF CIRCUMSTANCES; ILLEGALITY; RESERVE REQUIREMENTS 14.01 Change of Circumstances (a) If, after May 30, 1990, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (1) shall subject any Bank (or its Lending Office) to any tax, duty or other charge with respect to the Loan or its obligation to make such Loan, or any part thereof, or shall change the basis of taxation of payments to any Bank (or its Lending Office) of the principal of or interest on its Loan, or any 71 part thereof, or any other amounts due under this Agreement in respect of its Loan or its obligation to make the Loan, or any part thereof (except for changes in the rate of tax on the overall net income of such Bank or its Lending Office imposed by the jurisdiction in which such Bank's principal executive office or Lending Office is located); or (2) shall impose, modify or deem applicable any reserve, special deposit or similar requirement, (including, without limitation, any such requirement imposed by the Federal Reserve) against assets of, deposits with or for the accounts of, or credit extended by any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the London interbank market any other condition affecting its Loan, or any part thereof, or other indebtedness under the Agreement or its obligations to make the Loan; and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) of making or maintaining the Loan, or any portion thereof, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) under this Agreement with respect thereto, then, within 15 (fifteen) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay promptly for the account of such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. Such Bank shall submit to the Borrower and the Agent a certificate showing, in reasonable detail, the calculation of the amount of such increased cost. (b) If, after May 30, 1990, the adoption of any law, rule or regulation of any general applicability regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by a Bank (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency (including, without limitation, and whether promulgated or made before or after the Second Restatement Date, any law, regulation, interpretation, guideline or request contemplated by the report dated July 1988 entitled "International Convergence of Capital Measurement and Capital Standards" issued by the Basle Committee on Banking Regulations and Supervisory Practices), shall, in the determination of a Bank, have the effect of reducing the rate of return of such Bank's capital to a level below that which such Bank could have achieved as a consequence of its obligations hereunder but for such adoption, change or compliance (taking into consideration such Bank's policies with respect to capital adequacy), by an amount deemed by such Bank to be material in its sole and absolute discretion, then, within 15 (fifteen) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. 72 (c) Each Bank will notify the Borrower and the Agent promptly of any event of which it has knowledge, occurring after the First Restatement Date, which will entitle such Bank to compensation pursuant to this SECTION 14.01 and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this SECTION 14.01 and setting forth the additional amount or amounts to be paid to it under this Agreement shall be conclusive in the absence of manifest error. (d) Upon the occurrence of any of the events described in SECTION 14.01(A) or (B), the Borrower may prepay without premium or penalty except as otherwise provided in SECTION 12.04 such Bank's portion of the Loan together with all interest accrued thereon and all fees and other amounts (including amounts payable under SECTION 14.01(A) or (B) above) payable to such Bank hereunder, on giving not less than 10 (ten) days prior written notice to the Agent. Such Bank's Commitment shall be canceled on the giving of such notice. 14.02 ILLEGALITY (a) Notwithstanding anything to the contrary contained in this Agreement, if any change in law, regulation or treaty or in the interpretation or application thereof after May 30, 1990, by any authority charged with the administration thereof shall make it unlawful for any Bank to make, fund or maintain its portion of the Loan (although such Bank may lawfully maintain its Commitment) or to give effect to its obligations through its Lending Office as contemplated hereby, such Bank may give written notice thereof to the Agent to be forwarded by the Agent to the Borrower and the other Banks. Before giving such notice to the Agent, such Bank, to the reasonable extent possible, shall designate a different Lending Office if such designation will avoid the need for giving such notice. (b) Until such Bank notifies the Borrower and the Agent that the circumstances of the type described above no longer exist, the obligation of such Bank to make its portion of the Loan shall be suspended and the Borrower may, at its option, terminate such Bank's Commitment, by notice to such Bank and to the Agent, to be given within 30 (thirty) days after the date of notice by the Agent to the Borrower, as provided above. (c) If such Bank shall determine that it may not lawfully continue: (1) to maintain and fund its portion of the outstanding Loan to maturity; and (2) to maintain its Commitment to maturity, and shall so specify in such notice, the Borrower shall prepay, without premium or penalty except as otherwise provided in SECTION 12.04, forthwith (or if permitted by law, on the next 73 following Interest Payment Date) such Bank's portion of the Loan, together with all interest accrued thereon and all fees and other amounts payable to such Bank under this Agreement. Such Bank's obligations under this Agreement and its Commitment shall be canceled on the giving of such notice. 14.03 RESERVE REQUIREMENTS The Borrower shall pay to the Agent for the account of each Bank, so long as such Bank shall be required under regulations of the Federal Reserve to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, interest in addition to the applicable interest rate plus the applicable Margin on the unpaid principal amount of the applicable portion of the Loan advanced by such Bank, from the date of such Loan until such principal amount is paid in full, an amount equal to an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the rate (not including the applicable Margin) for the Interest Period for such Loan, from (ii) the rate obtained by dividing the rate described in CLAUSE (I) of this SECTION 14.03 by a percentage equal to 100% (one hundred percent) minus the Eurocurrency Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable. A certificate of each Bank setting forth in reasonable detail the calculation of the amount of such increased costs and such amounts as shall be necessary to compensate such Bank for such costs, shall be delivered to the Borrower and the Agent. The Borrower shall pay each Bank the amount shown as due on any such certificate within 30 (thirty) days after its receipt of the same. Each Bank that became a "Bank" pursuant to the Original Agreement prior to the Primary Syndication Completion Date waives the right to claim additional amounts based upon reserve requirements in effect on the date it became a Bank; provided, however, that such waiver does not apply with respect to reserve requirements to which such Bank is entitled pursuant to Regulation D. ARTICLE 15. REPRESENTATIONS AND WARRANTIES The Borrower represents and warrants as of the Second Restatement Date (which representations and warranties shall be deemed to be repeated on the first day of each Interest Period) and as of the date of each advance of the Revolving Portion existing during the term of this Agreement (except to the extent such representations and warranties are expressly made only in reference to another specific date) that: 15.01 CORPORATE EXISTENCE OF BORROWER AND SUBSIDIARIES The Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware with a registered office in the Federal Republic of Germany.

The execution and delivery of the Loan Documents by the Borrower, and its Subsidiaries, as the case may be, who are signatories thereto, do not contravene any provisions of the Certificate of Incorporation and By-Laws, or corresponding constitutive documents by whatever name, of the Borrower or its Subsidiaries. 76 15.08 BANKRUPTCY Neither the Borrower nor any of its Subsidiaries has taken any corporate action nor have any other steps been taken or legal proceedings been started or (to the best of the Borrower's knowledge and belief) been threatened against any of the Borrower or any of its Subsidiaries for the winding-up, dissolution, administration or reorganization (in each such case under bankruptcy or insolvency laws) or for the appointment of a receiver, administrator, administrative receiver, trustee or similar officer of it or them or of any or all of its or their assets or revenues, except the dissolution of Subsidiaries which are not Major Subsidiaries with respect to which notice is or has been given to the Agent. 15.09 NO DEFAULTS; NO LITIGATION Neither the Borrower nor any of its Subsidiaries is in breach of or in default under any agreement to which it is a party or which is binding on it or any of its or their assets, which breach or default could reasonably be expected to have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; and no action or administrative proceeding before any court, arbitration tribunal or governmental agency has been commenced or, to the Borrower's knowledge, threatened against the Borrower or any Subsidiary, or any assets of any of them, in which an adverse decision could reasonably be expected to have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole. As of the Second Restatement Date, SCHEDULE 5 sets forth a summary of each such action or administrative proceeding before any court, arbitration tribunal or governmental agency pending or, to the knowledge of the Borrower, threatened in writing, as of the Second Restatement Date which action or proceeding may result in liability to the Borrower and/or any Subsidiary in an amount in excess of DM 10,000,000 (Deutsche Mark Ten Million).

As of the Second Restatement Date, SCHEDULE 5 also sets forth, for each site or location, a brief description of all Environmental Claims involving amounts in excess of DM 10,000,000 (Deutsche Mark Ten Million) (or the equivalent amount in any currency). 15.11 FINANCIAL STATEMENTS The consolidated and consolidating group financial statements of the Borrower and its Subsidiaries as of December 31, 1995 and as of September 30, 1996, respectively, and for the year and period then ended, present fairly, in all material respects, the consolidated group financial position and results of operations of the Borrower and its Subsidiaries as of such dates and for such periods, all in conformity with German GAAP, and neither the Borrower nor any of its Subsidiaries had any material liabilities as of December 31, 1995 or as of September 30, 1996 (as applicable), which are not reflected in such financial statements. 78 15.12 NO MATERIAL ADVERSE CHANGE Since the preparation of the consolidated group financial statements of the Borrower and its Subsidiaries as of September 30, 1996, there has been no change which has had a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole. 15.13 ACCURATE INFORMATION The financial projections for the Borrower and NL Industries contained in the projection package dated January 15, 1997, were prepared in good faith based on assumptions believed by the management of the Borrower to be reasonable as of such date. 15.14 NO VIOLATION, DEFAULTS OR LIENS The execution and delivery by the Borrower and its Subsidiaries, as the case may be, of the Loan Documents and the exercise by the Borrower of its rights, and the performance by the Borrower and its Subsidiaries of their respective obligations, under the Loan Documents will not result in: (a) the creation of or require the imposition of any Lien in favor of any Person other than the Agent and/or the Banks; or (b) the existence of any event of default (howsoever called) under any agreement or contract to which the Borrower or any Subsidiary is a party or by which any of them or their properties are bound which event of default would have a Material Adverse Effect on any Company; or (c) the violation of any law or regulation, or by any judgment, decree or order, applicable to the Borrower or its Subsidiaries which violation would have a Material Adverse Effect on any Company. 15.15 ERISA (a) Except as disclosed in SCHEDULE 6 A attached hereto, with respect to all Pension Benefit Plans which are or have been maintained by the Borrower or any member of the Controlled Group: (1) there have not been any prohibited transactions, the aggregate liability for which either has not been satisfied in full or would have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; (2) none of such plans has been terminated, the aggregate liability for which either has not been satisfied in full or the liability for which would have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, 79 taken as a whole, and if any of such plans has not been terminated, the aggregate liability and potential liability of the Borrower, if all such plans were to terminate, would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; (3) none of such plans has any accumulated funding deficiency, whether or not waived, the aggregate liability for which either has not been satisfied in full or would have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; (4) neither the Borrower nor any member of the Controlled Group has incurred aggregate liabilities (excluding premium payments made as and when due) to the PBGC with respect to all such plans which liabilities would have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; (5) there have been no reportable events, the aggregate liability for which either has not been satisfied in full or would have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole. For purposes of this SECTION 15.15, the terms "accumulated funding deficiency" and "reportable event" shall have the respective meanings assigned thereto by ERISA and/or the Code. (b) Except as disclosed in SCHEDULE 6 B with respect to all Pension Benefit Plans currently maintained or participated in by the Borrower or another member of the Controlled Group, the amount for which the Borrower would be liable pursuant to the provisions of Section 4063 of ERISA would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole, if all such plans had terminated. (c) Except as disclosed in SCHEDULE 6 C, neither the Borrower nor any other member of the Controlled Group is now, nor has the Borrower or any other member of the Controlled Group during the preceding 10 (ten) years ever been, a contributing employer to a multiple employer plan or a Multiemployer Plan with respect to which the Borrower or any other member of the Controlled Group has: (1) withdrawn as a substantial employer or otherwise so as to become subject to the provisions of Section 4063 of ERISA or to any liability for withdrawal from such plan under either provisions of applicable non-U.S. laws or with respect to the applicable plan document, unless the aggregate liability and potential liability with respect to all such withdrawals has been satisfied in full or would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole; 80 (2) incurred or caused to occur a "complete withdrawal" (within the meaning of Section 4203 of ERISA) or a "partial withdrawal" (within the meaning of Section 4205 of ERISA) from a Multiemployer Plan that is a Pension Benefit Plan so as to incur withdrawal liability under Section 4201 of ERISA, or incurred or caused to incur a similar event which could result in liability under non-U.S. laws with respect to Non-U.S. Employee Plans unless the aggregate liability and potential liability for all such withdrawals has been satisfied in full or would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries taken as a whole; or (3) been a party to any transaction or agreement under which the provisions of Section 4204 of ERISA were applicable, unless Borrower can no longer be held liable for any withdrawal liability with respect to a Multiemployer Plan to be contributed to by the purchaser pursuant to such transaction or agreement or the amount of the withdrawal liability which could be imposed on Borrower if there were a partial or complete withdrawal with respect to all such Multiemployer Plans would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole. (d) Except as disclosed on SCHEDULE 6 D, the aggregate potential withdrawal liability of the Borrower with respect to all Multiemployer Plans and any similar liabilities of the Borrower and its Subsidiaries and potential liabilities under applicable non-U.S. laws or Non-U.S. Employee Plans would not have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole, if the Borrower and all members of the Controlled Group were to withdraw from all such Multiemployer Plans and were to incur all such liabilities and potential liabilities under applicable non-U.S. laws or with regard to the Non-U.S. Employee Plans. (e) Except as disclosed on SCHEDULE 6 E, there are no actions, suits or claims pending (other than routine claims for benefits) or, to the knowledge of the Borrower, threatened in writing which could reasonably be expected to be asserted against any Employee Plan maintained by the Borrower or against the Borrower or the assets of any such plan, the liability for which in the aggregate could have a Material Adverse Effect on the Borrower and its Consolidated Subsidiaries, taken as a whole.

THE AGENT AND THE BANKS 21.01 Each Bank hereby irrevocably appoints the Agent to act as its agent in connection with this Agreement and the Loan Documents and authorizes the Agent to exercise such rights, remedies, powers and discretion as are specifically delegated to the Agent by the terms of this Agreement and the Loan Documents together with all such rights, powers and discretion as are reasonably incidental thereto. 21.02 When acting in connection with the Loan Documents, the Agent may: (a) assume that no Default has occurred and that the parties thereto are not in breach or default of their respective obligations thereunder unless the officers of the Agent immediately responsible for matters concerning this Agreement shall have actual knowledge or shall have been notified in writing by a Bank that such Bank considers that a Default exists and is continuing and specifying the nature thereof; (b) assume that each Bank's Lending Office is that identified with its signature below and on SCHEDULE 1 until it has received from such Bank written notice designating some other office of such Bank as its Lending Office and continue to act upon such notice until the same is superseded by a further such notice; 115 (c) subject to the provisions of SECTION 20.02, engage and pay for the advice or services of any lawyers, accountants or other experts whose advice or services may to it seem necessary, expedient or desirable and fully rely upon any advice so obtained;

(b) be bound to account to any Bank for any sum or the profit element of any sum received by it for its own account; (c) be bound to disclose to any other Person any information relating to the Borrower or any of the Borrower's Affiliates received by it if such disclosure would or might in the opinion of any of the above Persons constitute a breach of any law or regulation or be otherwise actionable by suit of any Person; (d) be under any fiduciary duty towards any Bank or under any obligations other than those for which express provision is made herein; (e) be liable for any action taken or omitted to be taken except for their own gross negligence or wilful misconduct; or (f) be liable for any error in computing any amount payable to any Bank, provided, that the Agent, the Borrower and any affected Bank, upon discovery of such error, shall make such adjustments as may be required to correct such error. 21.05 Each Bank agrees to indemnify the Agent and its directors, officers, employees, agents and Affiliates to the extent not reimbursed by the Borrower in the proportion of its share in the Loan (or, if no amount is outstanding, its Commitment) for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent and its directors, officers, employees, agents or Affiliates in any way relating to or arising out of the First Restated Agreement, this Agreement or any other Loan Documents, or any other documents contemplated by or referred to herein or the transactions contemplated hereby (including, without limitation, the costs and expenses which the Borrower is obligated to pay under ARTICLE 20 but excluding, unless an Event of Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its Agent's agency duties hereunder) or the enforcement of any of the terms of the First Restated Agreement, this Agreement, the Loan Documents or of any such other documents, provided that no Bank shall be liable for any of the foregoing to the extent they arise from the Agent's gross negligence or wilful misconduct. 21.06 Each Bank agrees that the Agent shall not be responsible for the accuracy or completeness of any representation made (whether orally or otherwise) herein or in connection herewith, for the proper form, validity, effectiveness, adequacy or enforceability of the Original Agreement, the First Restated Agreement, this Agreement, any Guaranty, the Pledge Agreements, the Nordenham Mortgage, the Canadian Security Documents, the Cash Pledge Agreements or any of the other Loan Documents or for the creditworthiness of the Borrower, any Guarantor, Pledgor, Pledged Subsidiary or any Affiliate of the foregoing 117 entities. Neither the Agent nor any of its directors, officers, employees, agents or Affiliates shall be under any liability for or in respect of any action taken or omitted by any of them in relation to the Original Agreement, the First Restated Agreement, this Agreement, any Guaranty, the Pledge Agreements, the Nordenham Mortgage, the Canadian Security Documents, the Cash Pledge Agreements or any of the other Loan Documents except for their gross negligence or wilful misconduct. 21.07 The Agent may accept deposits from, lend money to and generally engage in any kind of banking or other business with the Borrower or any Affiliate, independently of the transactions contemplated herein. 21.08 It is understood and agreed by each Bank that it has been, and will continue to be, solely responsible, without reliance upon the Agent, for making its own independent appraisal of and investigations into the financial condition, creditworthiness and affairs of the Borrower, any Guarantor, the Pledgors, Pledged Subsidiaries and Affiliates of the foregoing entities and the value of the Collateral or the validity, enforceability or genuineness of the Original Agreement, the First Restated Agreement, this Agreement or any of the Loan Documents and accordingly each Bank confirms to the Agent that it has not relied, and will not hereafter rely, on the Agent: (a) to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or any Affiliates, director, officer, employee or agent thereof in connection with the Loan Documents or the transactions therein contemplated whether or not such information has been or is hereafter circulated to such Bank by the Agent; or (b) to assess or keep under review on its behalf the financial condition, creditworthiness or affairs of the Borrower or its Affiliates and the value and/or enforceability of the Collateral. 21.09 The Agent may at any time be removed by the Majority Banks upon at least 30 (thirty) days prior written notice to such Agent of such removal but only for cause consisting of gross negligence or wilful misconduct or following a declaration of insolvency by the appropriate regulators. The Agent may at any time resign from the agency upon not less than 45 (forty-five) days' notice to the Banks of its intention to do so and, if any such notice is given by the Agent, the Agent shall, upon the appointment of a successor agent as hereinafter provided for, cease to be under any further obligation as Agent hereunder. Within such period, the Majority Banks may appoint a successor agent with the consent of the Borrower, which consent will not be unreasonably withheld or delayed and if, before the expiry of such notice, such successor agent notifies the parties hereto that it accepts such appointment: (a) each reference herein to the "Agent" shall thereafter be construed as a reference to the successor agent; and 118 (b) the successor agent and the parties hereto other than the retiring Agent shall thereafter have such rights and obligations inter se as they would have if the successor agent had been named herein as the Agent. If no successor agent, appointed by the Majority Banks, notifies the parties hereto, prior to the expiry of the Agent's notice of its intention to retire from the agency giving rise to the need to appoint the same, of its acceptance of such appointment, the Agent may appoint any experienced and reputable bank having offices in London, Munich, New York City or Luxembourg to be the successor agent and, if it does and such successor agent notifies the parties hereto that it accepts such appointment: (i) each reference herein to the "Agent" shall thereafter be construed as a reference to the successor agent so appointed; and (ii) the successor agent so appointed upon execution of a counterpart of this Agreement and the parties hereto other than the retiring Agent shall thereafter have such rights and obligations inter se as they would have if the successor agent so appointed had been named herein as the Agent. Until the Borrower receives written notice of the appointment of a new Agent, the Borrower shall be entitled to continue to send notices and payments to the previously appointed Agent and otherwise to treat such Agent as the Agent for purposes of this Agreement. 21.10 If any Reference Bank shall be prepaid under this Agreement or shall cease to have any Commitment or after the Second Restatement Date cease to have any principal or interest owing to it hereunder, the Agent may in consultation with the Banks and the Borrower appoint a substitute Reference Bank. 21.11 The provisions of this ARTICLE 21 are solely for the benefit of the Agent and the Banks and neither the Borrower nor any Subsidiary or Affiliate of the Borrower shall have any rights (whether as third party beneficiary or otherwise) except as specifically provided herein. ARTICLE 22. NO WAIVER No failure to exercise and no delay in exercising on the part of the Agent or any Bank of any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or future exercise thereof, or the exercise of any other right, power or privilege. The rights and privileges herein provided are cumulative and not exclusive of any rights or remedies provided by law in equity or otherwise. This Agreement may be amended and any provision of this Agreement may be waived only with the consent of the Majority Banks, provided, however, that no amendment or waiver shall, unless in writing and signed by each Bank affected thereby, do any of the following: (1) reduce the principal or the rate of interest payable by the Borrower on any Loan or reduce any fees payable to the Banks under this Agreement; 119 (2) postpone the date fixed for the payment of principal of or interest on the Loan or any fees to the Banks under this Agreement; (3) increase the Commitment of any Bank or subject any Bank to any additional obligation to make Loans; or (4) amend this ARTICLE 22; provided, further, that no amendment or waiver shall be effected which releases or impairs or otherwise compromises any Collateral or substitutes Collateral without the prior written consent of the Majority Banks (662/3%) other than in the case of the NL Undertaking for which the consent of the Majority Banks shall be required; and provided further that no such amendment or waiver or consent, as the case may be, which has the effect of (i) increasing the duties or obligations of the Agent under this Agreement or of the Agent under any other Loan Document, or (ii) increasing the standard of care or performance required on the part of the Agent under this Agreement or of the Agent under any other Loan Document, or (iii) reducing or eliminating the indemnities or immunities to which the Agent is entitled hereunder (including any amendment or modification of this ARTICLE 22), shall be effective unless the same shall be signed by or on behalf of the Agent. ARTICLE 23. PARTIAL INVALIDITY; CHANGE IN ACCOUNTING PRINCIPLES 23.01 If at any time any provision of this Agreement or other Loan Documents to which the Borrower or any of its Affiliates is a signatory is or becomes illegal, invalid or unenforceable in any respect under the law of any jurisdiction, the legality, validity or enforceability of the remaining provisions under this Agreement or such Loan Document shall not in any way be affected or impaired thereby. Such illegal, invalid or unenforceable provisions shall be replaced by legal, valid and enforceable provisions, the economic and legal effects of which are as close as possible to that of the invalid illegal or unenforceable provisions. 23.02 If any changes in German GAAP or other applicable accounting principles after the First Restatement Date result in a change of the interpretation, calculation or method of calculation of financial covenants, ratios, standards or terms contained in this Agreement (the "Financial Covenants") which is materially different from the interpretation, calculation or method of calculation of the Financial Covenants on the First Restatement Date, the parties hereto agree to enter into negotiations with a view to amending the Financial Covenants so that the criteria for evaluating the financial condition of the Borrower and its Subsidiaries shall be the same as if such change had not been made. ARTICLE 24. ASSIGNMENTS, PARTICIPATION 24.01 The Borrower may not assign or transfer all or any of its rights, benefits and obligations under this Agreement without the prior written consent of the Majority Banks (662/3%); provided, however, that nothing in this SECTION 24.01 shall affect the ability of the 120 Borrower to merge or consolidate in accordance with the terms of SECTION 16.10. 24.02 (a) Notwithstanding any other provision contained in this Agreement or any other documents, no Bank may assign or transfer any of its interests under this Agreement except in accordance with the provisions of this SECTION 24.02 and no Bank may transfer, assign or grant participations in its rights and/or delegations under this Agreement except in accordance with this SECTION 24.02; provided, however, that nothing in this SECTION 24.02 or in this Agreement shall prevent, subject to SECTION 24.03, any Bank assigning or granting participations in such Bank's interests under this Agreement to such Bank's parent bank holding company or to any affiliate in which such Bank or parent bank holding company has the power to vote at least 33 1/3% of the voting securities issued by such affiliate for the election of the board of directors (or members of an equivalent governing body), provided, however, that such affiliate assignee may only further assign or subparticipate its interests in Loans pursuant to the terms of this ARTICLE 24 and provided, however, that such affiliate assignee cannot further assign or subparticipate its interests in Loans to any Person which is an affiliate pursuant to the provisions of SECTION 24.02(A). (b) Each Bank shall have the right to transfer, assign or grant participations in all or any part of its remaining rights and obligations under this Agreement on the basis and subject to the conditions set forth below in this SUBSECTION 24.02(B). (i) Each Bank may assign all or a portion of its rights and obligations under this Agreement to any Person in accordance with the terms of this SECTION 24.02.

Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least 5 (five) Business Days after the execution thereof (or such earlier date as shall have been agreed to by the assignor Bank, the assignee and the Agent), (A) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Bank hereunder and (B) the Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto). 121 (ii) Each Bank may sell participations to one or more banks or other financial institutions in all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Loans owing to it); provided, however, that (A) such Bank shall remain a "Bank" for all purposes of this Agreement and the transferee of such participation shall not constitute a Bank hereunder, (B) such Bank's rights and obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (C) no notice to or filing (including the filing of any registration or similar statement) with any governmental authority or regulatory body is required in connection with any participation, (D) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (E) the Borrower, the Guarantors, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement and (F) any agreement pursuant to which any Bank grants a participation in its rights with respect to the Loan shall provide that, with respect to such Loan, such Bank shall retain the sole right and responsibility to exercise the rights of such Bank, and enforce the obligations of the Bor rower relating to such Loan, including without limitation the right to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Documents and the right to take action to have the Loan declared due and payable pursuant to ARTICLE 18, provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement or any of the other Loan Documents without the consent of the participant that would: (1) reduce the principal or the rate of interest payable by the Borrower on any Loan or reduce any fees payable under this Agreement; (2) postpone any date fixed for the payment of principal of or interest on the Loan or any fees under this Agreement; (3) increase the Commitment of any Bank or subject any Bank to any additional obligation to make Loans; or (4) amend ARTICLE 22 or any other provision of this Agreement requiring the consent or other action of all the Banks. No participant shall have any rights under this Agreement to receive payments pursuant to SECTION 11.01 AND 14.01. 24.03 Assignments under this Agreement, including assignments made to an Affiliate of a Bank in accordance with SECTION 24.02(A), are subject to the condition that if, at the time of such assignment, the assignee would be subject to any greater Taxes than those to which 122 the assignor Bank is then subject, or thereafter, if the assignee would at any time be subject to any greater Taxes than those to which the assignor Bank would at such time have been subject, the assignee Bank shall and does hereby waive any right to claim and receive Taxes and additional amounts payable pursuant to SECTIONS 11.01 AND 14.01 in respect of the excess of the Taxes and additional amounts applicable to it over the Taxes and additional amounts applicable to the assignor Bank. 24.04 By executing and delivering an Assignment and Acceptance, the assignor Bank thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assignor Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, the Loan Documents, the Collateral or any other instrument or document furnished pursuant hereto; (ii) such assignor Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower, any Pledgor, any Guarantor or their Affiliates or the performance or observance by the Borrower or any such Pledgor, Guarantor or Affiliate of any of its obligations under this Agreement, other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in SECTION 15.11 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assignor Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement or any of the other Loan Documents; (v) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Bank. 24.05 The Agent shall maintain at its address referred to below a copy of each Assignment and Acceptance delivered to and accepted by it and records of the names and addresses of the Banks and the Commitment (including the Revolving Commitment) of, and principal amount of the Loan (including each portion thereof) owing to, each Bank from time to time.

The records shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice. 24.06 Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee, the Agent shall, if such Assignment and Acceptance has been completed and is 123 in substantially the form of EXHIBIT A hereto, as the case may be, (i) accept such Assignment and Acceptance, (ii) record the information contained therein, and (iii) give prompt notice thereof to the Borrower. 24.07 Each of the Agent and each Bank which is a signatory to this Agreement shall execute a Confidentiality Agreement in the form of EXHIBIT S attached hereto on or prior to the date of its execution of this Agreement.
