3.15Letter of Credit Payments.  Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall notify Contran and the Administrative Agent of such notice of drawing.  Not later than 10:00 a.m. (Dallas, Texas time) on the date of any payment by the L/C Issuer under a Letter of Credit, Contran shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing and thereby satisfy its Reimbursement Obligation with respect to such drawing.  If any Reimbursement Obligation shall remain outstanding at 10:00 a.m. (Dallas, Texas time) on the Business Day such Reimbursement Obligation is payable by Contran and by such time on such Business Day the Administrative Agent has not received either (a) a Notice of Borrowing delivered pursuant to Section 5.13 of this Agreement requesting that a Loan be made pursuant to Section 2.1 of this Agreement on such date in an amount at least equal to the aggregate principal amount of such unpaid Reimbursement Obligation, or (b) any other notice indicating that Contran intends to timely repay such unpaid Reimbursement Obligation with funds obtained from other sources, then the Administrative Agent shall be deemed to have received a Notice of Borrowing from Contran pursuant to Section 5.13 of this Agreement requesting that a Loan be made pursuant to Section 2.1 of this Agreement (with interest to accrue thereon at the Base Interest Rate) on the date such unpaid Reimbursement Obligation is due under this Agreement in an amount equal to such unpaid Reimbursement Obligation (which unpaid amount is referred to in this Agreement as the “Unreimbursed Amount”), and the procedures set forth in Section 5.16 of this Agreement shall be followed in making such a Loan.  A Loan of the type described in the preceding sentence shall be made notwithstanding Contran’s failure to satisfy all of the conditions set forth in Section 7.2 of this Agreement.

- 21 -

3.16Participations in Unpaid Reimbursement Obligation.  If it is legally impossible or impracticable (as determined by the Administrative Agent in its reasonable discretion) for Contran to obtain a Loan under the circumstances described in Section 3.15 of this Agreement (whether due to a termination or expiration of the Revolving Credit Facility, the bankruptcy of Contran, or otherwise) the Administrative Agent promptly shall notify the L/C Issuer and each Lender of such impossibility or impracticability.  Upon such notice (but without any further action), the L/C Issuer hereby agrees to grant to each Lender, and each Lender hereby agrees to acquire from the L/C Issuer, a participation in each Unreimbursed Amount equal to such Lender’s Applicable Percentage of the Unreimbursed Amount in question.

3.17Payments by the Lenders Pursuant to Participations in Letters of Credit.  Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided in Section 3.16 of this Agreement, immediately to pay the Administrative Agent, for the account of the L/C Issuer, such Lender’s Applicable Percentage of each Unreimbursed Amount.  Each Lender acknowledges and agrees that its obligation to acquire participations in Unreimbursed Amounts pursuant to Section 3.16 of this Agreement is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default, and that each payment made to purchase such a participation shall be made without any offset, abatement, withholding, or reduction whatsoever, provided that the conditions set forth in Section 7.2 of this Agreement were satisfied at the time of issuance of the Letter of Credit to which such Unreimbursed Amount relates.  Each Lender shall comply with its obligation under this Section 3.17 of this Agreement by wire transfer of immediately available funds to the Administrative Agent in the same manner as provided in Section 5.16 of this Agreement and the Administrative Agent promptly shall pay to the L/C Issuer amounts received by the Administrative Agent from the Lenders.

3.18Procedure Following Purchase of Participations in an Unreimbursed Amount.  The Administrative Agent shall notify Contran of any participations in any Unreimbursed Amount acquired by the Lenders pursuant to Section 3.16 of this Agreement.  Thereafter, payments by Contran in respect of such Unreimbursed Amount shall be made to the Administrative Agent and not to the L/C Issuer.  Any amounts received by the L/C Issuer in respect of an Unreimbursed Amount after receipt by the L/C Issuer of the proceeds of a sale of participations in such Unreimbursed Amount shall be remitted promptly to the Administrative Agent.  Any amounts received by the Administrative Agent in accordance with the preceding sentence shall be remitted promptly by the Administrative Agent to the Lenders that have made their payments pursuant to Section 3.17 of this Agreement and to the L/C Issuer, on a pro rata basis, as their interests (if any) may appear.

- 22 -

3.19Effect of Failure of a Lender to Pay its Participation in an Unreimbursed Amount.  If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the provisions of Sections 3.15 through 3.17 of this Agreement by the time specified in Sections 3.15 and 3.17 of this Agreement, as applicable, the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the Base Interest Rate.  A certificate of the L/C Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this Section 3.19 of this Agreement shall be conclusive in the absence of manifest error.

3.20Consequence of Contran’s Failure to Repay Reimbursement Obligation.  If Contran fails to timely repay a Reimbursement Obligation, and that obligation cannot be repaid in accordance with the terms of Section 3.15 of this Agreement and becomes the subject of participations purchased by the Lenders in accordance with Sections 3.16 and 3.17 of this Agreement, an Event of Default shall occur, unless Contran repays the Unreimbursed Amount in question within three (3) Business Days of the date on which the Lenders obtain the participations in such Unreimbursed Amount.  Contran’s failure to timely repay a Reimbursement Obligation that results in an Unreimbursed Amount that is repaid with a Loan in accordance with Section 3.15 of this Agreement shall not constitute an Event of Default.  However, Contran acknowledges and agrees that following Contran’s failure to timely repay a Reimbursement Obligation in the manner required by the terms of Sections 3.12 and 3.15 of this Agreement, the L/C Issuer without prior notice to Contran may refuse in its sole and absolute discretion to issue additional Letters of Credit for the account of Contran.

3.21Letters of Credit Issued for Subsidiaries or Affiliates.  Notwithstanding that a Letter of Credit issued or outstanding under this Agreement is in support of any obligations of, or is for the account of, a Subsidiary or an Affiliate of Contran, Contran shall be obligated to reimburse the L/C Issuer hereunder for any and all drawings under such Letter of Credit.  Contran hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries or Affiliates of Contran inures to the benefit of Contran, and that Contran’s business derives substantial benefits from the businesses of its Subsidiaries and Affiliates.

3.22No Issuance of Letters of Credit During Pendency of an Event of Default.  Contran shall not be entitled to obtain Letters of Credit at any time that a Default or an Event of Default exists.

- 23 -

3.23Applicability of ISP.  Unless otherwise expressly agreed by the L/C Issuer and Contran when a Letter of Credit is issued, the rules of the ISP shall apply to each Letter of Credit.

5.8Voluntary Prepayments.  Contran may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Loans in whole or in part without premium or penalty; provided that (a) such notice must be received by the Administrative Agent not later than 11:00 a.m. Dallas, Texas time on the date of prepayment of Loans; and (b)  any prepayment of Loans shall be in a principal amount of $500,000 or an integral multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding.  Each such notice shall specify the date and amount of such prepayment.  The Administrative Agent promptly shall notify each Lender of the Administrative Agent’s receipt of each such notice and of the amount of such Lender’s Applicable Percentage of such prepayment.  If such notice is given by Contran, Contran shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.  Each such prepayment shall be applied to the Loans of the Lenders in accordance with their respective Applicable Percentages.

5.9Mandatory Prepayments.  If at any time the Administrative Agent shall notify Contran that a Collateral Deficiency exists, then within five (5) Business Days of Contran’s receipt of such notice, Contran at its option shall do one of the following:

(a)prepay Loans to the extent necessary to eliminate the Collateral Deficiency, together with accrued interest on the principal amount prepaid to the date of such prepayment, and, if necessary upon the event that all Loans have been prepaid, cash collateralize the L/C Obligations, so that, immediately following such prepayment or cash collateralization, no Collateral Deficiency exists; or

(b)provide the Administrative Agent with a perfected first priority security interest in Additional Security so that no Collateral Deficiency exists (it being expressly agreed that prior to the pledge of any Additional Security other than TIMET Shares, Contran first shall cause Valhi Holding to pledge to the Administrative Agent all TIMET Shares owned by Valhi Holding that are not otherwise subject to a Lien and, thereafter, Contran shall pledge to the Administrative Agent all TIMET Shares owned by Contran that are not otherwise subject to a Lien).  Any pledge of TIMET Shares or other Additional Security by Contran in accordance with the preceding sentence shall be effected pursuant to a Pledge and Security Agreement in a form substantially identical to the Pledge Agreement and acceptable to the Administrative Agent in its sole and absolute discretion.

Nothing in this Section 5.9 of this Agreement or in any other provision of this Agreement shall obligate the Administrative Agent to monitor, or to otherwise calculate or determine, whether a Collateral Deficiency exists under this Agreement and, in that regard, Contran hereby acknowledges and agrees that it is Contran’s responsibility to monitor the Available Collateral Amount and to report promptly to the Administrative Agent the existence of any Collateral Deficiency.

5.10Mandatory Termination of Commitments.  The Commitments and the L/C Commitment, shall terminate (a) on the Maturity Date, and (b) as specified in Section 12.2 of this Agreement.  Upon termination of the Commitments and the L/C Commitment, the Lenders (or the L/C Issuer, as applicable) shall have no further obligation to extend credit under this Agreement and any unutilized portion of any credit commitment no longer shall be available to Contran.

- 25 -

5.11Voluntary Termination or Reduction of Commitments.  Upon notice to the Administrative Agent, Contran may terminate the Commitments, or from time to time permanently reduce the Commitments, subject to the following conditions:

(a)any such notice shall be received by the Administrative Agent not later than 11:00 a.m. Dallas, Texas time five (5) Business Days prior to the date of termination or reduction of the Commitments;

(b)any partial reduction of the Commitments shall be in an aggregate amount of $5,000,000, or an integral multiple of $1,000,000 in excess thereof;

(c)Contran shall not terminate the Commitments if, after giving effect to such termination and to any concurrent prepayments of the Obligations under this Agreement, the Total Outstanding Amount would exceed the Aggregate Commitments;

(d)Contran shall not reduce the Commitments to an amount that, after giving effect to such reduction and to any concurrent prepayments of the Obligations under this Agreement, would be less than the Total Outstanding Amount; and

(e)if, after giving effect to any reduction of the Commitments, the L/C Commitment exceeds the amount of the Aggregate Commitments, the L/C Commitment automatically shall be reduced by the amount of such excess.

The Administrative Agent promptly shall notify the Lenders of any notice of termination or reduction of the Aggregate Commitments provided by Contran pursuant to this Section 5.11 of this Agreement.  Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Applicable Percentage.

5.12The Lenders’ Note Records.  Contran irrevocably authorizes each of the Lenders to make or cause to be made, at or about the time of any Loan, or at the time of receipt of any payment on the Notes, an appropriate notation in its records reflecting (as the case may be) the making of such Loan or the receipt of such payment.  The outstanding amount of the Loans set forth in the records of the Lenders shall be prima facie evidence of the amount thereof owing and unpaid to the Lenders.  Notwithstanding the foregoing, the failure of any Lender to record (or any error in so recording) the amount of any Loan or payment in the Lender’s records shall not limit or otherwise affect the obligations of Contran under this Agreement, or under any Note, to make payments of principal of or interest on any Note when due.

5.13Notice of Borrowing.  Whenever Contran desires to obtain a Loan under this Agreement, Contran shall give the Administrative Agent a written Notice of Borrowing (or a telephonic notice promptly confirmed by a written Notice of Borrowing), which notice shall be irrevocable and which must be received no later than 11:00 a.m. Dallas, Texas time on the Business Day on which the requested Loan is to be made.  Such Notice of Borrowing shall specify the effective date and amount of each Loan.  If the Administrative Agent receives a Notice of Borrowing after the time specified in the first sentence of this Section 5.13 of this Agreement, such Notice of Borrowing shall not be effective.  If the written confirmation of any telephonic notification differs in any material respect from the action taken by the Administrative Agent, the records of the Administrative Agent shall control in the absence of manifest error.

- 26 -

5.14Reserved.

5.15Funding of Loans.  Loans shall be made by the Lenders in accordance with their respective Applicable Percentages.  The obligations of the Lenders under this Agreement to make Loans and to fund participations in Letters of Credit, and to make payments pursuant to Section 15.12 of this Agreement are several and not joint.  The failure of any Lender to make any Loan, to fund any such participation, or to make any payment under Section 15.12 of this Agreement on any date required under this Agreement shall not relieve any other Lender of its corresponding obligation to do so on such date, provided, however, that no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation, or to make its payment under Section 15.12 of this Agreement.

5.16Funding Notifications.  The Administrative Agent shall notify the Lenders of (a) any requested Loan, (b) the Advance Date of the requested Loan, and (c) the amount of each Lender’s Applicable Percentage of such Loan.  If such notice is given by the close of the Administrative Agent’s business on the Business Day on which the Administrative Agent receives an effective Notice of Borrowing as provided in Section 5.13 of this Agreement, each Lender not later than noon Dallas, Texas time on the proposed Advance Date of such Loan shall make available to the Administrative Agent, at its Dallas, Texas office, in immediately available funds, such Lender’s Applicable Percentage of the amount of the requested Loan.  Upon receipt by the Administrative Agent of such amount, the Administrative Agent shall make available to Contran the aggregate amount of such Loan by crediting the proceeds of the Loan to the operating checking account maintained by Contran with the Administrative Agent.

5.17Method of Payments.  All payments of principal of and interest by Contran in respect of Loans and any other amounts due by Contran to the Lenders under this Agreement shall be made by Contran to the Administrative Agent (for the benefit of the Lenders in accordance with their Applicable Percentages) at the Administrative Agent’s Dallas, Texas office (or at such other location that the Administrative Agent may from time to time designate), in each case in immediately available funds denominated in Dollars.  All payments by Contran under this Agreement and under any of the other Loan Documents shall be made without set-off or counterclaim and free and clear of and without deduction for any Taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions, or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein, unless Contran is compelled by law to make such deduction or withholding.  If any such obligation is imposed upon Contran with respect to any amount payable by it under this Agreement or under any of the other Loan Documents, Contran shall pay to each Lender such additional amount in Dollars as shall be necessary to enable such Lender to receive the same net amount that such Lender would have received on such due date had no such obligation been imposed upon Contran.  Contran promptly shall deliver to the Administrative Agent certificates or other valid vouchers or evidence of payment satisfactory to the Administrative Agent in its reasonable discretion for all Taxes or other charges deducted from or paid with respect to payments made by Contran under this Agreement or under such other Loan Document.  Contran hereby authorizes the Administrative Agent to debit Contran’s depository accounts as identified to Administrative Agent from time to time to make the payments owed by Contran pursuant to this Agreement.  The Administrative Agent shall not be obligated to debit such accounts to collect the payments owed by Contran pursuant to this Agreement and the Administrative Agent’s failure to do so shall not relieve Contran of its obligation to make the payments in question.  Any payment received by the Administrative Agent after noon, Dallas, Texas time shall be deemed to have been made on the next following Business Day and interest shall accrue to that day.  The Administrative Agent shall make reasonable efforts to wire transfer each Lender’s Applicable Percentage of all payments and recoveries on the same Business Day if received by the Administrative Agent by noon, Dallas, Texas time, or on the next Business Day if received after noon, Dallas, Texas time (or on a day other than a Business Day).

- 27 -

5.18Funding by the Lenders; Presumption by the Administrative Agent.  Unless the Administrative Agent shall have received notice from a Lender prior to a proposed Advance Date that such Lender will not make available to the Administrative Agent such Lender’s Applicable Percentage of such borrowing, the Administrative Agent may assume that such Lender has made such share available on such Advance Date in accordance with Section 5.16 of this Agreement and may, in reliance upon such assumption, make available to Contran a corresponding amount.  In such event, if a Lender has not in fact made its Applicable Percentage of the Loan available to the Administrative Agent, then such Lender and Contran severally agree to pay to the Administrative Agent immediately on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Contran to but excluding the date of payment to the Administrative Agent, at (a) in the case of a payment to be made by such Lender, the Base Interest Rate, and (b) in the case of a payment to be made by Contran, the interest rate applicable to Loans.  If Contran and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent promptly shall remit to Contran the amount of such interest paid by Contran for such period.  If such Lender pays its Applicable Percentage of the Loan in question to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing.  Any payment by Contran shall be without prejudice to any claim that Contran may have against a Lender that shall have failed to make such payment to the Administrative Agent.

5.19Payments by Contran; Presumptions by the Administrative Agent.  Unless the Administrative Agent shall have received notice from Contran prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuer under this Agreement that Contran will not make such payment, the Administrative Agent may assume that Contran has made such payment on such date in accordance with this Agreement and may, in reliance upon such assumption, distribute to the Lenders or the L/C Issuer, as the case may be, the amount due.  In such event, if Contran has not in fact made such payment, then each of the Lenders or the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the L/C Issuer, with interest thereon, for each day from and including the date such amount is distributed to such Lender or the L/C Issuer to but excluding the date of payment to the Administrative Agent, at the Base Interest Rate.  A notice from the Administrative Agent to any Lender or Contran with respect to any amount owing under Section 5.18 or this Section 5.19 of this Agreement shall be conclusive in the absence of manifest error.

5.20Failure to Satisfy Conditions Precedent.  If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Section V of this Agreement, and such funds are not made available to Contran by the Administrative Agent because the conditions to the applicable credit extension set forth in Section VII are not satisfied or waived in accordance with the terms of this Agreement, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

- 28 -

5.21Funding Source.  Nothing in this Agreement shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

5.22Insufficient Funds.  If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, Reimbursement Obligations (or Unreimbursed Amounts, as applicable), interest, and fees then due under this Agreement, such funds so received and available shall be applied (a) first, toward payment of interest and fees then due under this Agreement, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (b) second, toward payment of principal of Loans and Reimbursement Obligations (or Unreimbursed Amounts, as applicable) then due under this Agreement, ratably among the parties entitled thereto in accordance with the amounts of principal of Loans and Reimbursement Obligations (or Unreimbursed Amounts, as applicable) then due to such parties.

5.23Compliance with Margin Regulations.  For purposes of complying with Regulation U and X, at any time there are Loans outstanding under this Agreement that are considered “purpose credit” within the meaning of Regulation U or X, each Lender’s Loans and its Applicable Percentage of the L/C Obligations shall be treated as two separate extensions of credit (the “Reg U Credit” and the “Non-Reg U Credit” of such Lender, and collectively the “Reg U Credits”, and the “Non-Reg U Credits” of the Lenders), as follows:

(a)The aggregate amount of the Reg U Credit of such Lender shall be an amount equal to the principal portion of such Lender’s outstanding Loans utilized by Contran for the purpose of buying or carrying margin stock; and

(b)The aggregate amount of the Non-Reg U Credit of such Lender shall be an amount equal to the sum of (i) such Lender’s aggregate outstanding Loans minus such Lender’s Reg U Credit, plus (ii) such Lender’s Applicable Percentage of the L/C Obligations.

5.24 Regulation U Records.  Each lender shall maintain its records to identify the Reg U Credit and the Non-Reg U Credit of such Lender, and, solely for the purposes of complying with Regulation U, the Reg U Credit and Non-Reg U Credits shall be treated as separate extensions of credit.

5.25Benefits of Collateral.  The benefits of the security interest in any of the Collateral that is margin stock (the “Margin Stock Collateral”) created by the Pledge Agreement shall be allocated first to the benefit and security of the payment of the principal and interest on the Reg U Credits of the Lenders and of all other amounts payable by Contran under this Agreement in connection with the Reg U Credits (collectively, the “Reg U Amounts”) and second, only after the payment in full of the Reg U Amounts, to the benefit and security of the payment of the principal and interest on the Non-Reg U Credits of the Lenders and of all other amounts payable by Contran under this Agreement in connection with the Non-Reg U Credits (collectively, the “Non-Reg U Amounts”).  The benefits of the security in Collateral other than Margin Stock Collateral shall be allocated first to the benefit and security of the payment of the Non-Reg U Amounts and second, only after the payment in full of the Non-Reg U Amounts, to the benefit and security of the payment of the Reg U Amounts.

- 29 -

5.26Lenders’ Responsibilities.  Each Lender shall be responsible for its own compliance with and administration of the provisions of Section 5.23 of this Agreement and Regulation U, and the Administrative Agent shall have no responsibility for any determinations or allocations made or to be made by any Lender as required by such provisions.  The Administrative Agent shall transmit to Contran on behalf of any Lender any requests made by such Lender pursuant to Section 5.23 of this Agreement and shall transmit from Contran to such Lender any information provided by Contran in respect to inquiries made under Section 5.23 of this Agreement, or otherwise required to be delivered by Contran to the Lenders pursuant to Section 5.23 of this Agreement.

SECTION VI

TAXES, YIELD PROTECTION, AND ILLEGALITY

6.1Payments Free of Taxes.  Any and all payments by or on account of any obligation of Contran under this Agreement or under any other Loan Document shall be made free and clear of, and without reduction or withholding for, any Indemnified Taxes or Other Taxes, provided, however, that if Contran shall be required by applicable Law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 6.1 of this Agreement), the Administrative Agent, the Lender, or the L/C Issuer, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (b) Contran shall make such deductions, and (c) Contran timely shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable Law.  Without limiting the provisions of the preceding sentence, Contran shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.  As soon as practicable after any payment of Indemnified Taxes or Other Taxes by Contran to a Governmental Authority, Contran shall deliver to the Administrative Agent the original (or a certified copy) of the receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment, or other evidence of such payment satisfactory to the Administrative Agent in its reasonable discretion.

6.2Indemnity by Contran With Respect to Certain Taxes.  Contran shall indemnify the Administrative Agent, each Lender, and the L/C Issuer, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under Section 6.1 of this Agreement) paid by the Administrative Agent, such Lender, or the L/C Issuer, as the case may be, and any penalties, interest, and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to Contran by a Lender or the L/C Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, shall be conclusive absent manifest error.

6.3Status of Lenders.  Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which Contran is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement, or under any other Loan Document, shall deliver to Contran (with a copy to the Administrative Agent), at the time or times prescribed by applicable Law, or reasonably requested by Contran or the Administrative Agent, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without withholding, or at a reduced rate of withholding.  In addition, any Lender, if requested by Contran or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law, or reasonably requested by Contran or the Administrative Agent, as will enable Contran or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.  Without limiting the generality of the foregoing, in the event that Contran is resident for tax purposes in the United States of America, any Foreign Lender shall deliver to Contran and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of Contran or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(d)any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed, together with such supplementary documentation as may be prescribed by applicable Law to permit Contran to determine the withholding or deduction required to be made.

- 31 -

6.4Treatment of Certain Refunds.  If the Administrative Agent, a Lender, or the L/C Issuer determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by Contran, or with respect to which Contran has paid additional amounts pursuant to Section 6.1 of this Agreement, it shall pay to Contran an amount equal to such refund (but only to the extent of additional amounts paid, or indemnity payments made, by Contran under Sections 6.1 or 6.2 of this Agreement with respect to the Taxes or Other Taxes giving rise to such refund), net of all out of pocket expenses of the Administrative Agent, such Lender, or the L/C Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided, however, that Contran, upon the request of the Administrative Agent, such Lender, or the L/C Issuer, agrees to repay the amount paid over to Contran (plus any penalties, interest, or the other changes imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender, or the L/C Issuer in the event the Administrative Agent, such Lender, or the L/C Issuer is required to repay such refund to such Governmental Authority.  This Section 6.4 of this Agreement shall not be construed to require the Administrative Agent, any Lender, or the L/C Issuer to make available its tax returns (or any other information relating to its tax status or situation that it deems confidential) to Contran or any other Person.

6.5Reserved.

(b)subject any Lender or the L/C Issuer to any Tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit, or change the basis of taxation of payments to such Lender or the L/C Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 6.1 of this Agreement and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the L/C Issuer); or

(c)impose on any Lender or the L/C Issuer any other condition, cost, or expense affecting this Agreement or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the L/C Issuer of participating in, issuing, or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the L/C Issuer under this Agreement (whether of principal, interest, or any other amount) then, upon request of such Lender or the L/C Issuer, Contran will pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered.

- 32 -

6.8Capital Requirements.  If any Lender or the L/C Issuer determines that any Change in Law affecting such Lender or the L/C Issuer, or any lending office of such Lender, or such Lender’s or the L/C Issuer’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the L/C Issuer’s capital, or on the capital of such Lender’s or the L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the L/C Issuer, to a level below that which such Lender or the L/C Issuer, or such Lender’s or the L/C Issuer’s holding company, could have achieved but for such Change in Law (taking into consideration such Lender’s or the L/C Issuer’s policies and the policies of such Lender’s or the L/C Issuer’s holding company with respect to capital adequacy), then from time to time Contran shall pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer, or such Lender’s or the L/C Issuer’s holding company, for any such reduction suffered.

6.9Certificates for Reimbursement.  A certificate of a Lender or the L/C Issuer setting forth the amount or amounts necessary to compensate such Lender or the L/C Issuer, or its holding company, as the case may be, as specified in Sections 6.7 or 6.8 of this Agreement and delivered to Contran shall be conclusive absent manifest error.  Contran shall pay such Lender or the L/C Issuer, as the case may be, the amount shown as due on any such certificate within ten days after receipt thereof.

6.10Delay in Requests.  Any failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to Sections  6.7 or 6.8 of this Agreement shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation, provided, however, that Contran shall not be required to compensate a Lender or the L/C Issuer pursuant to Sections 6.7 or 6.7 of this Agreement for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies Contran of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

6.14Mitigation Obligations.  If any Lender requests compensation under Section 6.7 of this Agreement, or requires Contran to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 6.1 of this Agreement, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans under this Agreement, or to assign its rights and obligations under this Agreement to another of its offices, branches, or affiliates, if, in the judgment of such Lender, such designation or assignment (a) would eliminate or reduce amounts payable pursuant to Sections 6.1 or 6.7 of this Agreement, as the case may be, in the future, and (b) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender.  Contran hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

- 33 -

6.15Replacement of Lenders.  If (a) any Lender requests compensation under Section 6.7 of this Agreement, (b) Contran is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 6.1 of this Agreement, (c) any Lender is a Defaulting Lender, (d) any Lender is an Impacted Lender and, as a result thereof, the L/C Issuer has declined to issue a Letter of Credit, or (e) any Lender does not agree to any consent, waiver, or amendment requiring approval of all Lenders and the Required Lenders have agreed to such consent, waiver, or amendment, then Contran may, at Contran’s sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 13.1 of this Agreement), all of its interests, rights, and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations, provided that:

(w)           Contran shall have paid to the Administrative Agent the assignment fee specified in Section 13.1(f) of this Agreement;

(x)           such assigning Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in Letters of Credit, accrued interest thereon, accrued fees, and all other amounts payable to it under this Agreement and under the other Loan Documents (including any amounts under Section 13.1(f) of this Agreement) from the assignee (to the extent of such outstanding principal and accrued interest and fees), or Contran (in the case of all other amounts);

(y)           in the case of any such assignment resulting from a claim for compensation under Section 6.7 of this Agreement, or payments required to be made pursuant to Section 6.1 of this Agreement, such assignment will result in a reduction in such compensation or payments thereafter; and

(z)           such assignment does not conflict with applicable Law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Contran to require such assignment and delegation cease to apply.

6.16Defaulting Lender.  The following provisions of this Agreement relate to any Defaulting Lender:

- 34 -

(a)In addition to the rights and remedies that may be available to the Administrative Agent or Contran under this Agreement or applicable law, if at any time a Lender is a Defaulting Lender, (i) such Defaulting Lender’s right to collect fees under Section 2.7 of this Agreement, to collect L/C Fees, or to participate in the administration of the Loans, this Agreement, and the other Loan Documents, including, without limitation, any right to vote in respect of, to consent to, or to direct any action or inaction of the Administrative Agent, or to be taken into account in the calculation of the Required Lenders, shall be suspended while such Lender remains a Defaulting Lender, and (ii) the Commitment of such Defaulting Lender (or, if such Commitment has been terminated pursuant to Sections 5.10, 5.11, or 12.2 of the Agreement, the Total Outstanding Amount of such Defaulting Lender) shall be excluded for purposes of making a determination of Required Lenders; provided, however, that the Commitments of such Defaulting Lender may not be increased and the period of such Commitments may not be extended without such Defaulting Lender’s consent.  If a Lender is a Defaulting Lender because it has failed to make timely payment to the Administrative Agent of any amount required to be paid to the Administrative Agent under this Agreement (without giving effect to any notice or cure periods), in addition to other rights and remedies that the Administrative Agent or Contran may have under the immediately preceding provisions or otherwise, the Administrative Agent shall be entitled (i) to collect interest from such Defaulting Lender on such delinquent payment for the period from the date on which the payment was due until the date on which the payment is made at the Base Interest Rate, (ii) to withhold or set off and to apply in satisfaction of the defaulted payment and any related interest, any amounts otherwise payable to such Defaulting Lender under this Agreement or any other Loan Document until such defaulted payment and related interest has been paid in full and such default no longer exists, and (iii) to bring an action or suit against such Defaulting Lender in a court of competent jurisdiction to recover the defaulted amount and any related interest.  Any amounts received by the Administrative Agent in respect of a Defaulting Lender’s Loans shall not be paid to such Defaulting Lender and shall be held uninvested by the Administrative Agent and either applied against the purchase price of such Loans under the following subsection, or paid to such Defaulting Lender upon the default of such Defaulting Lender being cured.

(b)Any Lender that is not a Defaulting Lender shall have the right, but not the obligation, in its sole discretion, to purchase all of a Defaulting Lender’s Commitment and such Defaulting Lender’s Applicable Percentage of all Outstanding Amounts.  If more than one Lender exercises such right, each such Lender shall have the right to purchase such proportion of such Defaulting Lender’s Commitment and its Applicable Percentage of all Outstanding Amounts on a pro rata basis in accordance with the Commitments of such Lenders immediately before such purchase.  Upon any such purchase, the Defaulting Lender’s interest in its Loans and its rights under this Agreement (but not its liability in respect thereof, or under the Loan Documents or this Agreement, to the extent the same relate to the period prior to the effective date of the purchase) shall terminate on the date of purchase, and the Defaulting Lender promptly shall execute all documents reasonably requested to surrender and transfer such interest to the purchaser thereof, subject to and in accordance with the requirements set forth in Section 13.1 of this Agreement, including an Assignment and Assumption Agreement in form acceptable to the Administrative Agent.  The purchase price for the Commitments of a Defaulting Lender shall be equal to the Defaulting Lender’s Applicable Percentage of the amount of the principal balance of (and accrued and unpaid interest and fees on) the Loans outstanding and owed by Contran.  The purchaser shall pay to the Defaulting Lender in immediately available funds on the date of such purchase the principal of (and accrued and unpaid interest and fees on) the Loans made by such Defaulting Lender under this Agreement (it being understood that such accrued and unpaid interest and fees may be paid pro rata to the purchasing Lender and the Defaulting Lender by the Administrative Agent at a subsequent date upon receipt of payment of such amounts from Contran).  Prior to payment of such purchase price to a Defaulting Lender, the Administrative Agent shall apply against such purchase price any amounts retained by the Administrative Agent pursuant to the last sentence of subsection (a) of this Section 6.16 of this Agreement.  The Defaulting Lender shall be entitled to receive amounts owed to it by Contran under the Loan Documents that accrued prior to the date of the default by the Defaulting Lender, to the extent the same are received by the Administrative Agent from or on behalf of Contran.  There shall be no recourse against any Lender or the Administrative Agent for the payment of such sums, except to the extent of the receipt of payments from any other party, or in respect of the Loans.

- 35 -

(c)At any time a Lender becomes a Defaulting Lender, then, at the Administrative Agent’s option in its sole discretion, but without prejudice to Contran’s rights under Section 6.15 of this Agreement, such Defaulting Lender’s Commitment shall be reduced to the amount of such Defaulting Lender’s outstanding Loans, but such Defaulting Lender’s Applicable Percentage in respect of all outstanding Letters of Credit shall not be changed.  In addition, if any Lender is a Defaulting Lender at the time any payment is to be made by the Lenders to the L/C Issuer pursuant to Section 3.15 or Section 3.17 of this Agreement, no Lender that is not a Defaulting Lender shall be obligated to make a payment to the L/C Issuer that would cause the aggregate principal amount of such Lender’s Loans, plus such Lender’s Applicable Percentage (without giving effect to any Commitment reduction pursuant to the foregoing provisions) of the aggregate maximum amount available to be drawn under outstanding Letters of Credit, to exceed such Lender’s Commitment (or, if all of the Commitments have terminated, such Lender’s Commitment at the time of such termination, adjusted for any assignments by or to such Lender).

(d)To the extent permitted by applicable law, until the breach, event, or occurrence that caused a Lender to become a Defaulting Lender under this Agreement has been cured or remedied and such Lender no longer is a Defaulting Lender, (i) any voluntary prepayment of the Loans shall, at the Administrative Agent’s option, be applied to the Loans of the other Lenders as if such Defaulting Lender had no Loans outstanding, and (ii) any mandatory prepayment of the Loans shall be applied to the Loans of the other Lenders (but not to the Loans of such Defaulting Lender) as if such Defaulting Lender had funded all Loans that such Defaulting Lender is obligated to fund under this Agreement, it being understood and agreed that Contran shall be entitled to retain any portion of any mandatory prepayment of the Loans that is not paid to such Defaulting Lender solely as a result of the operation of the provisions of this clause and the amount of the Commitment as at any date of determination shall be calculated as if such Defaulting Lender had funded all Loans that such Defaulting Lender is obligated to fund pursuant to this Agreement.

6.17Survival of Obligations.  All of Contran’s obligations under this Section VI of this Agreement shall survive termination of the Aggregate Commitments, repayment of all other Obligations under this Agreement, and resignation of the Administrative Agent.

10.1Use of Proceeds.  The proceeds of Loans shall be used by Contran only for general corporate purposes and to purchase margin stock; provided, however, that no proceeds of any Loan shall be used by Contran to purchase or carry any margin stock (as defined in Regulations U and X) in violation of Regulations U and X.  Contran shall request Letters of Credit solely to support contingent obligations of Contran (other than obligations in respect of borrowed money) and, in the case of Letters of Credit issued for the joint and several account of Contran and a Subsidiary or Affiliate of Contran, to support contingent obligations of such Subsidiary or Affiliate (other than obligations in respect of borrowed money).

- 55 -

13.2Register.  The Administrative Agent, acting solely for this purpose as an agent of Contran, shall maintain at its designated office a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans and L/C Obligations owing to, each Lender pursuant to the terms of this Agreement from time to time (the “Register”).  The entries in the Register shall be conclusive, and Contran, the Administrative Agent, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.  The Register shall be available for inspection by Contran and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

13.3Participations.  Any Lender may at any time, without the consent of or notice to Contran or the Administrative Agent, sell participations to any Person (other than a natural person or Contran or any of Contran’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations) owing to it; provided that (a) such Lender’s obligations under this Agreement shall remain unchanged, (b) such Lender shall remain solely responsible to the other parties to this Agreement for the performance of such obligations, and (c) Contran, the Administrative Agent, the Lenders, the L/C Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.  Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification, or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification, or waiver described in the second sentence of Section 15.1 of this Agreement that affects such Participant.  Subject to Section 13.4 of this Agreement, Contran agrees that each Participant shall be entitled to the benefits of Sections 6.1, 6.2, 6.7,  and 6.8 of this Agreement to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 13.1 of this Agreement.  To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 15.2 of this Agreement as though it were a Lender, provided such Participant agrees to be subject to Section 15.3 of this Agreement as though it were a Lender.

13.4Limitations Upon Participant Rights.  Participant shall not be entitled to receive any greater payment under Sections 6.1, 6.2, 6.7, or 6.8 of this Agreement than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Contran’s prior, written consent.  A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Sections 6.1 and 6.2 of this Agreement unless Contran is notified of the participation sold to such Participant and such Participant agrees, for the benefit of Contran, to comply with Section 6.3 of this Agreement as though it were a Lender.

- 56 -

13.5Certain Pledges.  Any Lender at any time may pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations under this Agreement or substitute any such pledgee or assignee for such Lender as a party to this Agreement.

13.6Resignation as the L/C Issuer after Assignment.  Notwithstanding anything to the contrary contained in this Agreement, if at any time PlainsCapital assigns all of its Commitment and Loans pursuant to Section 13.1 of this Agreement, PlainsCapital may, upon thirty (30) days’ notice to Contran and the Lenders, resign as the L/C Issuer.  In the event of any such resignation as the L/C Issuer, Contran shall be entitled to appoint from among the Lenders a successor L/C Issuer under this Agreement, provided, however, that no failure by Contran to appoint any such successor shall affect the resignation of PlainsCapital as the L/C Issuer.  If PlainsCapital resigns as the L/C Issuer, it shall retain all the rights, powers, privileges, and duties of the L/C Issuer under this Agreement with respect to all Letters of Credit outstanding as of the effective date of its resignation as the L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Loans, or fund risk participations in Unreimbursed Amounts, pursuant to Section 3.15 and Sections 3.16 through 3.18, respectively, of this Agreement).  Upon the appointment of a successor L/C Issuer, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges, and duties of the retiring L/C Issuer, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession, or make other arrangements satisfactory to PlainsCapital to effectively assume the obligations of PlainsCapital with respect to such Letters of Credit.

14.9No Other Duties.  Anything herein to the contrary notwithstanding, none of the Lenders listed on the cover page of this Agreement shall have any powers, duties, or responsibilities under this Agreement, or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the L/C Issuer under this Agreement.

14.12Holders.  The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless and until a written notice of the assignment, transfer, or endorsement thereof, as the case may be, shall have been filed with the Administrative Agent.  Any request, authority, or consent of any Person or entity who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee, assignee, or indorsee, as the case may be, of such Note, or of any Note or Notes issued in exchange therefor.

15.2Right of Setoff.  If an Event of Default shall have occurred and be continuing, each Lender, the L/C Issuer, and each of their respective Affiliates hereby is authorized by Contran at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the L/C Issuer, or any such Affiliate to or for the credit or the account of Contran against any and all of the obligations of Contran now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer, irrespective of whether or not such Lender or the L/C Issuer shall have made any demand under this Agreement or any other Loan Document, and although such obligations of Contran may be contingent or unmatured, or are owed to a branch or office of such Lender or the L/C Issuer different from the branch or office holding such deposit or obligated on such indebtedness.  The rights of each Lender, the L/C Issuer, and their respective Affiliates under this Section 15.2 of this Agreement are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer, or their respective Affiliates may have.  Each Lender and the L/C Issuer agrees to notify Contran and the Administrative Agent promptly after any such setoff and application, provided, however, that the failure to give such notice shall not affect the validity of such setoff and application.

15.3Sharing of Payments by the Lenders.  If any Lender shall, by exercising any right of setoff or counterclaim, or otherwise, obtain payment (excluding any amounts received by the L/C Issuer to secure the obligations of a Defaulting Lender or an Impacted Lender to fund risk participations under this Agreement) in respect of any principal of or interest on any of its Loans or other obligations under this Agreement resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon, or other such obligations, greater than its pro rata share thereof, as provided in this Agreement, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided, however, that:

(y)           if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

- 64 -

(z)           the provisions of this Section 15.3 of this Agreement shall not be construed to apply to (i) any payment made by Contran pursuant to and in accordance with the express terms of this Agreement, or (ii) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans, or participations in Reimbursement Obligations, to any assignee or participant, other than Contran or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

Contran consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against Contran rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of Contran in the amount of such participation.

15.4No Waivers; Remedies Cumulative.  No failure by the Administrative Agent or any Lender to exercise any right, power, or remedy under this Agreement or any Loan Document, and no delay by the Administrative Agent or any Lender in exercising any right, power, or remedy under this Agreement or any Loan Document, shall operate as a waiver thereof.  No single or partial exercise of any right, power, or remedy of the Administrative Agent or any Lender under this Agreement or any other Loan Document shall preclude any other or further exercise thereof, or the exercise of any other right, power, or remedy of the Administrative Agent or any Lender.  The exercise of any right, power, or remedy of the Administrative Agent or any Lender shall in no event constitute a cure or waiver of any Event of Default under this Agreement, the Notes, or any other Loan Document, or a waiver of the right of the Administrative Agent or any Lender or the holder of any of the Notes to exercise any other right under this Agreement, the Notes, or any other Loan Document, unless in the exercise of such right, all obligations of Contran under this Agreement, the Notes, and all other Loan Documents are paid in full.  The rights and remedies provided in this Agreement and the Loan Documents are cumulative and are not exclusive of any right or remedy provided by law.  Time is of the essence and the provisions of this Agreement and the other Loan Documents shall be enforced strictly.

15.5Enforcement.  Notwithstanding anything to the contrary contained in this Agreement or in any other Loan Document, the authority to enforce rights and remedies under this Agreement and under the other Loan Documents against Contran or Valhi Holding, or either of them, shall be vested exclusively in, and all actions and proceedings at law in connection with such enforcement shall be instituted and maintained exclusively by, the Administrative Agent in accordance with Section 12.3 of this Agreement, and applicable law, for the benefit of all the Lenders and the L/C Issuer.  The foregoing shall not prohibit (a) the Administrative Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as the Administrative Agent) under this Agreement and under the other Loan Documents, (b) the L/C Issuer from exercising the rights and remedies that inure to its benefit (solely in its capacity as the L/C Issuer) under this Agreement and under the other Loan Documents, (c) any Lender from exercising setoff rights in accordance with Section 15.2 of this Agreement (subject to the terms of Section 15.3 of this Agreement), or (d) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to Contran under any Debtor Relief Law.  Furthermore, if at any time there is no Person acting as the Administrative Agent under this Agreement and under the other Loan Documents, then (y) the Required Lenders shall have the rights otherwise ascribed to the Administrative Agent pursuant to Section 12.3 of this Agreement, and (z) in addition to the matters set forth in clauses (b), (c), and (d) of the preceding sentence and subject to Section 15.3 of this Agreement, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

15.14Payments Set Aside.  To the extent any payments in respect of the Obligations (or any proceeds of any Collateral, including, but not limited to, the proceeds received by the Lenders as a result of any enforcement proceeding or setoff), or any part thereof, subsequently are invalidated, declared to be fraudulent or preferential, set aside, or required to be repaid to a trustee, receiver, or any other Person under any law or equitable cause, then, to the extent of such recovery, the Obligation or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and shall continue in full force and effect, and the Administrative Agent’s and the Lenders’ rights, powers, and remedies under this Agreement and the Loan Documents shall continue in full force and effect, as if such payment had not been made, or such enforcement proceeding or setoff had not occurred.  In such event, each Loan Document automatically shall be reinstated and Contran shall take such action as reasonably may be requested by the Administrative Agent and the Lenders to effect such reinstatement.

15.15Survival of Certain Agreements.  The agreements set forth in Sections 15.10 through 15.14 of this Agreement shall survive the resignation of the Administrative Agent, the replacement of any Lender, the termination of the Aggregate Commitments, and the repayment, satisfaction, or discharge of all of the Obligations.

PROMISSORY NOTE

(__________________ Bank)

$__________________ _________________

For value received, the undersigned, CONTRAN CORPORATION (“Contran”), a Delaware corporation, hereby promises to pay to the order of ________________________ (the “Lender”) on or before the Maturity Date the principal sum of _________ million and no/100 Dollars ($_____________) or, if less, the aggregate outstanding principal amount of the Loans (as defined in the Credit Agreement referred to below) made by the Lender to Contran, together with interest on the unpaid principal amount of each such Loan from the date of such Loan until such principal amount is paid in full, at such interest rates, and at such times, as are specified in the Credit Agreement.

This Note is one of the promissory notes referred to in, and is entitled to the benefits of, and is subject to the terms of, the Credit Agreement of even date herewith (as the same may be further amended or modified from time to time, the “Credit Agreement”) among Contran, the Lender, the other financial institutions parties thereto, and PlainsCapital Bank, as the Administrative Agent (the “Administrative Agent”).  Capitalized terms used in this Note that are defined in the Credit Agreement and not otherwise defined in this Note have the meanings assigned to such terms in the Credit Agreement.  The Credit Agreement, among other things, (a) provides for the making of Loans by the Lender to Contran from time to time in an aggregate amount not to exceed at any time outstanding the Dollar amount first above mentioned, and (b) contains provisions for acceleration of the maturity of this Note upon the happening of certain events stated in the Credit Agreement and for prepayments of principal prior to the maturity of this Note upon the terms and conditions specified in the Credit Agreement.

Both principal and interest owed by Contran pursuant to this Note are payable in lawful money of the United States of America to the Administrative Agent at 2911 Turtle Creek Blvd, Suite 1300, Dallas, Texas 75219 (or at such other location or address as may be specified by the Administrative Agent in writing to Contran) in same day funds.  The Lender shall record all Loans and payments of principal made under this Note, but no failure of the Lender to make such recordings shall affect Contran’s repayment obligations under this Note.

Except as specifically provided in the Credit Agreement, Contran hereby waives presentment, demand, protest, notice of intent to accelerate, notice of acceleration, and any other notice of any kind.  No failure to exercise, and no delay in exercising, any rights hereunder on the part of the holder of this Note shall operate as a waiver of such rights.

Contran promises to pay all reasonable out-of-pocket costs and expenses, including reasonable attorneys’ fees, as provided in Section 15.10 of the Credit Agreement, incurred in the collection and enforcement of this Note.

- 1 -

This Note shall be governed by and construed in accordance with the laws of the state of Texas, without regard to conflict of laws principles.

CONTRAN HEREBY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS PROMISSORY NOTE OR ANY OTHER AGREEMENT ENTERED INTO IN CONNECTION HEREWITH, ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY, OR ANY OF THE ACTIONS OF THE LENDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE, OR ENFORCEMENT OF THIS PROMISSORY NOTE.

Notwithstanding any provision of this Note or any other agreement or commitment between Contran, Administrative Agent and Lender, whether written or oral, express or implied, Lender shall never be entitled to charge, receive, or collect, nor shall amounts received hereunder be credited so that Lender shall be paid, as interest a sum greater than interest at the Maximum Rate.  It is the intention of the parties that this Note, and all instruments securing the payment of this Note or executed or delivered in connection therewith, shall comply with applicable law.  If Lender ever contracts for, charges, receives or collects anything of value which is deemed to be interest under applicable law, and if the occurrence of any circumstance or contingency, whether acceleration of maturity of this Note, prepayment of this Note, delay in advancing proceeds of this Note, or any other event, should cause such interest to exceed the maximum lawful amount, any amount which exceeds interest at the Maximum Rate shall be applied to the reduction of the unpaid principal balance of this Note or any other indebtedness owed to Lender by  Contran, and if this Note and such other indebtedness are paid in full, any remaining excess shall be paid to Contran.  In determining whether the interest exceeds interest at the Maximum Rate, the total amount of interest shall be spread, prorated and amortized throughout the entire term of this Note until its payment in full.  The term “Maximum Rate” as used in this Note means the maximum nonusurious rate of interest per annum permitted by whichever of applicable United States federal law or Texas law permits the higher interest rate, including to the extent permitted by applicable law, any amendments thereof hereafter or any new law hereafter coming into effect to the extent a higher Maximum Rate is permitted thereby.  If at any time the Rate shall exceed the Maximum Rate, the interest rate hereunder shall be automatically limited to the Maximum Rate until the total amount of interest accrued hereunder equals the amount of interest which would have accrued if there had been no limitation to the Maximum Rate.  To the extent, if any, that Chapter 303 of the Texas Finance Code, as amended, (the “Act”) is relevant to Lender for purposes of determining the Maximum Rate, the parties elect to determine the Maximum Rate under the Act pursuant to the “weekly ceiling” from time to time in effect, as referred to and defined in §303.001-303.016 of the Act; subject, however, to any right Lender subsequently may have under applicable law to change the method of determining the Maximum Rate. Lender and Contran expressly agree that Chapter 346 (“Chapter 346”) of the Texas Finance Code shall not apply to this Note or to any advances under this Note and that neither this Note or any such advances shall be governed by or subject to the provisions of Chapter 346 in any manner whatsoever.
