(c) Upon any mandatory prepayment of Loans required pursuant to Section 2.8(a) as the result of an Asset Sale involving Collateral, the Commitment shall be permanently reduced by an amount equal to the lesser of (i) 50% of the Net Cash Proceeds received in such Asset Sale and (ii) the amount of the Commitment then in effect.

Section 2.4. Credit Enhancements.

(a) On the terms and subject to the conditions contained in this Agreement, Lender agrees to provide one or more Credit Enhancements at the request of Borrower from time to time during the period commencing on the Effective Date and ending on the earlier of the Termination Date and 30 days prior to the Scheduled Termination Date; provided, however, that Lender shall not be under any obligation to provide any Credit Enhancement if:

(i) the applicable conditions contained in Sections 3.1 and 3.2 are not then satisfied;

(ii) after giving effect to the issuance of such Credit Enhancement, the aggregate principal amount of Loans outstanding would exceed the Loan Availability;

(iii) Lender, in its sole discretion, is not satisfied with the relevant documentation proposed to evidence such Credit Enhancement; or

(iv) the issuance of such Credit Enhancement shall have the effect of preventing the occurrence of an Event of Default under Section 9.1(g) or remedying any such Event of Default.

(b) In no event shall the term of any Credit Enhancement be more than one year after the date of issuance thereof; provided, however, that any Credit Enhancement with a one-year term may provide for the renewal thereof for additional one-year periods.

(c) In connection with the provision of each Credit Enhancement, Borrower shall give the Lender at least 10 days’ prior written notice (a “Credit Enhancement Request”), in such written or electronic form as is acceptable to Lender, of the requested Credit Enhancement. Such notice shall describe in reasonable detail the purposes of such Credit Enhancement, the nature and amount of the underlying obligation, the proposed effective date of such requested Credit Enhancement (which day shall be a Business Day), the date on which such Credit Enhancement is to expire (which date shall be a Business Day), and the Person for whose benefit the requested Credit Enhancement is to be provided.

101

(d) Subject to Section 2.2 and the satisfaction of the conditions set forth in this Section 2.4, Lender shall, on the requested date, provide a Credit Enhancement on behalf of Borrower.

(e) (i) Prior to the issuance of any Credit Enhancement by Lender, and as a condition of such issuance, Borrower shall have delivered to Lender a reimbursement agreement, in such form as Lender may require (each a “Reimbursement Agreement”), signed by Borrower, and such other documents or items as may be required pursuant to the terms thereof. In the event of any conflict between the terms of any Reimbursement Agreement and this Agreement, the terms of this Agreement shall govern.

(ii) In addition to the Reimbursement Agreements contemplated by Section 2.4(e)(i), Borrower and Lender are parties to a Reimbursement Agreement effective as of January 1, 2004 (the “Univation Reimbursement Agreement”) pursuant to which Borrower has a reimbursement obligation (the “Univation Reimbursement Obligation”) for any funds, services or other goods provided to Exxon Chemical Licensing Company, ExxonMobil Chemical Company, Union Carbide Subsidiary C, Inc. or Univation Technologies, LLC pursuant to the Univation Undertaking. Notwithstanding the terms of the Univation Reimbursement Agreement, the Univation Undertaking shall not be treated as a Credit Enhancement under this Agreement, including, without limitation, for the purposes of Section 2.10 (Fees).

(f) At such time as Lender is required to advance funds, services, or other items of value pursuant to any Credit Enhancement or the Univation Undertaking, such Credit Enhancement or used portion of the Univation Undertaking shall become a Reimbursement Obligation, and Borrower agrees to pay to Lender the amount of all Reimbursement Obligations on demand with interest thereon, irrespective of any claim, set-off, defense or other right which such Borrower may have at any time against Lender or any other Person. In the event that Lender makes any payment under any Credit Enhancement or the Univation Undertaking and Borrower shall not have repaid such amount to Lender pursuant to this clause (f) or such payment is rescinded or set aside for any reason, such Reimbursement Obligation shall be payable on demand with interest thereon computed from the date on which such Reimbursement Obligation arose to the date of repayment in full at the rate of interest applicable to past due Loans during such period, and then Lender shall, notwithstanding whether or not the conditions precedent set forth in Section 3.2 shall have been satisfied (which conditions precedent Lender hereby irrevocably waives), be deemed to have made a Loan to Borrower in the principal amount of such unpaid Reimbursement Obligation.

(g) Borrower’s obligation to pay each Reimbursement Obligation shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever, including the occurrence of any Default or Event of Default, and irrespective of:

(i) any lack of validity or enforceability of any Credit Enhancement or the Univation Undertaking or any Loan Document, or any term or provision therein;

(ii) any amendment or waiver of or any consent to or departure from all or any of the provisions of any Credit Enhancement or the Univation Undertaking or any Loan Document (provided, that any such amendment shall have been approved in writing by Borrower if the effect of such amendment would have resulted in an increase in Borrower’s applicable Credit Enhancement Obligations);

(iii) the existence of any claim, right of set-off, defense or other right that Borrower or any of its Subsidiaries or other party guaranteeing, or otherwise obligated with, Borrower, any Subsidiary or other Affiliate thereof or any other Person may at any time have against the beneficiary under any Credit Enhancement or the Univation Undertaking, Lender or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction;

(iv) any document presented under a Credit Enhancement or the Univation Undertaking proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

102

(v) payment by Lender under a Credit Enhancement or the Univation Undertaking against presentation of a document that does not comply with the terms of such Credit Enhancement or the Univation Undertaking; and

(vi) any other act or omission to act or delay of any kind of Lender or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of Borrower’s obligations hereunder.

Any action taken or omitted to be taken by Lender under or in connection with any Credit Enhancement or the Univation Undertaking shall not form the basis of any resulting liability of Lender to Borrower. In determining whether documents presented under a Credit Enhancement or the Univation Undertaking comply with the terms thereof, Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Credit Enhancement or the Univation Undertaking, Lender may rely exclusively on the documents presented to it under such Credit Enhancement or the Univation Undertaking as to any and all matters set forth therein, including reliance on the amount therein requested to be paid under such Credit Enhancement or the Univation Undertaking, whether or not the amount due to the beneficiary thereunder equals such amount and whether or not any document presented pursuant to such Credit Enhancement or the Univation Undertaking proves to be insufficient in any respect, if such document on its face appears to be in order.

Section 2.5. Repayment of Loans. Borrower shall repay the entire unpaid principal amount of the Loans on the Termination Date or on such earlier date that the Loans become due and payable hereunder.

Section 2.6. Evidence of Debt, Obligations of Borrower.

(a) Lender shall maintain in accordance with its usual practice an account or accounts evidencing Indebtedness of Borrower to Lender resulting from each Loan by Lender from time to time under this Agreement, including the amounts of principal and interest payable and paid to Lender from time to time under this Agreement. The entries made in any such account or accounts shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations recorded therein absent manifest error; provided, however, that the failure of Lender to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrowers to repay the Loans in accordance with their terms.

(b) Notwithstanding any other provision of this Agreement, in the event that Lender requests that Borrower execute and deliver a promissory note or notes payable to Lender in order to evidence the Indebtedness owing to Lender by Borrower hereunder, Borrower will promptly execute and deliver a note or notes to Lender evidencing any Loans of Lender, substantially in the form of Exhibit B.

Section 2.7. Optional Prepayments. Borrower may (in addition to the obligations under Section 2.8), prepay the outstanding principal amount of the Loans at any time in whole or in part without prepayment premium or penalty.

Section 2.8. Mandatory Prepayments.

(a) Upon receipt by Borrower or any of its Subsidiaries of Net Cash Proceeds arising from an Asset Sale (other than Asset Sales permitted by Section 8.3), Equity Issuance, Debt Issuance or Insurance Event, Borrower shall immediately prepay its Loans such that the aggregate amount of all such payments is equal to 100% of such Net Cash Proceeds. Any such mandatory prepayment shall be applied in accordance with Section 2.11(c) below.

(b) If at any time the aggregate principal amount of Loans exceeds the Commitment then, at such time Borrower shall prepay its Loans then outstanding such that the aggregate amount of all such payments is equal to such excess. Any such mandatory prepayment shall be applied in accordance with Section 2.11(c) below.

(c) Borrower agrees that all available funds in an Approved Deposit Account of Borrower shall be applied on a daily basis in accordance with Section 2.11(c). If there are no Loans outstanding and no other Obligations are then due and payable, then the funds in such Approved Deposit Account shall be retained in such Approved Deposit Account.

103

Section 2.9. Interest.

(a) Rate of Interest. All Loans and the outstanding amount of all other Obligations shall bear interest at the Applicable Rate as in effect from time to time, (i) in the case of Loans, on the unpaid principal amount thereof from the date such Loans are made and (ii) in the case of such other Obligations, from the date such other Obligations are due and payable until, in all cases, paid in full.

(b) Interest Payments. Interest accrued on each Loan shall be payable in cash in arrears (i) on the twenty-fifth day of each calendar month, commencing on April 25, 2003, and (ii) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Loan.

(c) Default Interest. Notwithstanding the rates of interest specified in Section 2.9(a) or elsewhere herein, effective immediately upon the occurrence of an Event of Default, and for as long thereafter as such Event of Default shall be continuing, the principal balance of all Loans and the amount of all other Obligations due and payable shall bear interest at a rate which is two percent (2%) per annum in excess of the rate of interest applicable to such Obligations from time to time.

Section 2.9. Fees.

(a) Credit Enhancement Fees. With respect to each Credit Enhancement provided by Lender hereunder, Borrower agrees to pay Lender a fee accruing at a rate per annum equal to two and one-half percent (2.5%) of the maximum Credit Enhancement Contingent Liabilities of Borrower to Lender outstanding from time to time under each such Credit Enhancement, payable in arrears (A) on the first day of each calendar month commencing on the first such day following the issuance of each such Credit Enhancement and (B) on the Termination Date; provided, that the fee accruing on the portion of the aggregate Credit Enhancements Contingent Liabilities that is equal to the Deposited Cash Collateral shall be equal to one and a quarter percent (1.25%), provided, further, that during the continuance of an Event of Default, all of such fees shall be increased by two percent (2%) per annum and shall be payable on demand.

(b) No Other Fees. Except as expressly provided in Section 2.10(a), no fees of any kind will be paid by Borrower to Lender or any of Lender’s Affiliates, pursuant to this Agreement or otherwise, as a result of the financial accommodations provided by Lender under this Agreement or any other Loan Document, including any unused commitment fees, closing fees, funding fees, monitoring fees, documentation fees or other fees.

(c) Cash Collateralized Credit Enhancements Rolled Into Future Facility. With respect to the closing of any Future Facility, Lender agrees that it will not charge any commitment fee on the portion of the commitment related to the Credit Enhancements that are rolled into the Future Facility to the extent such Credit Enhancements are Cash Collateralized Credit Enhancements, provided, however, that this clause (c) will be effective only with respect to one Future Facility.

Section 2.10. Payments and Computations; Protective Advances.

(a) All computations of interest and fees shall be made by Lender on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest and fees are payable. Each determination by Lender of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(b) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be.

Section 7.9. Credit Enhancements and Cash Collateral.

(a) On a daily basis, Borrower agrees, at all times and from time to time following the Effective Date and subject to Section 2.11(c), to deposit any cash, other amounts and credit balances of Borrower, and Borrower hereby instructs Lender to deposit cash, other amounts and credit balances of Borrower held by Lender, into one or more Cash Collateral Accounts, until there is Deposited Cash Collateral in an amount equal to the sum of (a) 105% of the sum of all outstanding Credit Enhancement Obligations which are denominated in U.S. dollars, and (b) 125% of the sum of all outstanding Credit Enhancement Obligations (if any) which are denominated in currencies other than U.S. dollars; provided, that in its discretion Borrower may at any time and from time to time elect not to deposit (and may request Lender not to deposit) any cash, other amounts and credit balances of Borrower in a Cash Collateral Account; provided, further, that such request shall not

109

otherwise alter the requirements of this Section 7.9(a) or the conditions to the release of the Step 2 Released Collateral. Such Deposited Cash Collateral shall bear interest for the benefit of Borrower at a rate per annum equal to LIBOR plus 0.125%, which interest shall be payable monthly and shall accrue regardless of whether Lender has drawn, borrowed against or otherwise used all or part of such Deposited Cash Collateral pursuant to Section 7.9(c). Lender may (but shall be under no obligation to) from time to time after the deposit of the Deposited Cash Collateral, apply all or part of such Deposited Cash Collateral then held to the payment of any amounts, in accordance with Section 2.11(c), as shall have become or shall become due and payable by Borrower to Lender. Lender shall promptly give written notice of any such application; provided, however, that the failure to give such written notice shall not invalidate any such application. To the extent that Borrower has Credit Enhancements that are not fully cash collateralized in accordance with this Section 7.9(a) and elects not to deposit (or requests Lender not to deposit) any cash, other amounts and credit balances of Borrower in a Cash Collateral Account, such cash, other amounts and credit balances not deposited in a Cash Collateral Account will be deposited in an Approved Deposit Account.

(b) Following the end of each calendar month following the Effective Date, Lender shall determine the aggregate amount of the Credit Enhancement Obligations outstanding at the end of such calendar month (the “Remaining Contingent Liabilities”) and, if the Deposited Cash Collateral exceeds an amount equal to the sum of (a) 105% of the sum of all Remaining Contingent Liabilities which are denominated in U.S. dollars and (b) 125% of the sum of all Remaining Contingent Liabilities (if any) which are denominated in currencies other than U.S. dollars, Lender shall release such excess to Borrower within 30 days of the end of such calendar month.

(c) Borrower and Lender hereby agree that, subject to the terms and conditions of this Agreement, Lender shall be allowed in its discretion to draw, borrow against and otherwise use and apply funds in any Cash Collateral Account (and any other cash collateral provided by Borrower) for Lender’s purposes. With respect to the Cash Collateralized Credit Enhancements, the sole security with respect to the face value of the Cash Collateralized Credit Enhancements shall be the Deposited Cash Collateral, and no other portion of the Collateral shall be available as security in respect of the Cash Collateralized Credit Enhancements, provided that the remaining Collateral shall continue to secure all other Obligations relating to or associated with such Cash Collateralized Credit Enhancements.

(d) Lender shall have a perfected first priority lien on the Cash Collateral Account and on all cash, other amounts therein and credit balances thereto. As long as any of the Obligations or the Commitment remain outstanding, neither Borrower nor any Person or entity claiming by, through or under Borrower, nor any Person other than Lender shall have any control over the use of, or any right to effect a withdrawal from, the Cash Collateral Account. Lender shall at all times have control, and be permitted to use, draw, close, and otherwise exclusively administer and be the depositary bank’s customer (as defined in Section 4-104 of the UCC) with respect to the Cash Collateral Account.

(e) Borrower and Lender hereby acknowledge that upon the deposit of certain additional cash collateral in a Cash Collateral Account pursuant to the terms and conditions of the Amended and Restated Pledge and Security Agreement, the Step 2 Released Collateral shall be released.

In no event shall the amount of interest due or payable hereunder exceed the maximum rate of interest allowed by Requirement of Law, and in the event any such payment is inadvertently made by Borrower or inadvertently received by Lender, then such excess sum shall be credited as a payment of principle, unless Borrower shall notify Lender in writing that it elects to have such excess sum returned forthwith.
