or Lender may, upon written notice to the other party at any time terminate in whole or reduce in part the unused portion of the Commitment. Any such

make any Loan (including any Loan request outstanding at such time) or provide any Credit Enhancement pursuant to Section 2.4 shall immediately terminate, and
(ii) in the case where the Commitment is reduced, the obligation of Lender to make any Loan shall immediately be limited to the amount of such reduced Commitment.

(b)   In
the event of termination of the Commitment pursuant to Section 2.3(a), Lender may, at any time and from time to time, demand
payment from Borrower of all or any part of the outstanding Loans together with all accrued and unpaid interest thereon; provided that the repayment date shall be specified in Lender's notice and at
least 30 days following Borrower's receipt of written notice from Lender.

(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.

(d)   Upon
any mandatory prepayment of Loans required pursuant to Section 2.8(a) as the result of an Insurance Event, the Commitment shall

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:



(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.

(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.



35

---





(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:



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

36

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.

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.

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.

retained in such Approved Deposit Account.

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

Section
7.8.    Approved Deposit Accounts and Cash Management System.

(a)   Borrower

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 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 rateper annumequal to LIBOR plus 0.125%, which interest shall be payable monthly and shall accrue regardless

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. Any determination of Remaining Contingent
Liabilities hereunder shall be conclusive and binding for all purposes, absent manifest error. Except as provided in the foregoing sentence, neither Borrower nor any Person claiming on behalf of or
through Borrower, nor any Person other than Lender, shall have any right to withdraw any portion of the Deposited Cash Collateral at any time prior to the termination of all outstanding Credit
Enhancements. Lender will deliver to Borrower the Deposited Cash Collateral or any other cash collateral held by Lender (including any amounts Lender has drawn, borrowed against or otherwise used)
within 15 days after the date in which all obligations of Lender with respect to any underlying Credit Enhancement are released and not renewed by Lender and all Obligations related thereto
have been indefeasibly terminated.

(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
