(A)

The definition of “Market Quotation” shall be deleted in its entirety and replaced with the following:

“Market Quotation” means, with respect to one or more Terminated Transactions, an offer which, when made, is capable of becoming legally binding upon acceptance (any such offer, a “Firm Offer”) which is (1) made by a Reference Market-maker that is an Eligible Replacement, (2) for an amount that would be paid to Party B (expressed as a negative number) or by Party B (expressed as a positive number) in consideration of an agreement between Party B and such Reference Market-maker to enter into a transaction (the “Replacement Transaction”) that would have the effect of preserving for such party the economic equivalent of any payment or delivery (whether the underlying obligation was absolute or contingent and assuming the satisfaction of each applicable condition precedent) by the parties under Section 2(a)(i) in respect of such Terminated Transactions or group of Terminated Transactions that would, but for the occurrence of the relevant Early Termination Date, have been required after that date, (3) made on the basis that Unpaid Amounts in respect of the Terminated Transaction or group of Transactions are to be excluded but, without limitation, any payment or delivery that would, but for the relevant Early Termination Date, have been required (assuming satisfaction of each applicable condition precedent) after that Early Termination Date is to be included and (4) made in respect of a Replacement Transaction with commercial terms substantially the same as those of this Agreement (save for the exclusion of provisions relating to Transactions that are not Terminated Transactions).”

(B)

The definition of “Settlement Amount” shall be deleted in its entirety and replaced with the following:

“Settlement Amount” means, with respect to any Early Termination Date, an amount (as determined by Party B (or the Depositor on its behalf)) equal to:

(1) If a Market Quotation for the relevant Terminated Transaction or group of Terminated Transactions is selected by Party A and accepted by Party B so as to become legally binding on or before the day falling ten Local Business Days after the day on which the Early Termination Date is designated (or such later day as Party B may specify in writing to Party A, which in any event will not be later than the Early Termination Date) (such day, the “Latest Settlement Amount Determination Day”), the Termination Currency Equivalent of the amount (whether positive or negative) of such Market Quotation; or

(2)  If no Market Quotation for the relevant Terminated Transaction or group of Terminated Transactions has been selected by Party A and accepted by Party B so as to become legally binding on or before the Latest Settlement Amount Determination Day, Party B’s Loss (whether positive or negative and without reference to any Unpaid Amounts) for the relevant Terminated Transaction or group of Terminated Transactions.

(C)

For the purpose of clause (4) of the definition of Market Quotation, Party B shall determine in its sole discretion, acting in a commercially reasonable manner, whether a Firm Offer is made in respect of a Replacement Transaction with commercial terms substantially the same as those of this Agreement (save for the exclusion of provisions relating to Transactions that are not Terminated Transactions).

(D)

At any time on or before the Latest Settlement Amount Determination Day at which two or more Market Quotations remain capable of becoming legally binding upon acceptance, Party B shall be entitled to accept only the lowest of such Market Quotations (for the avoidance of doubt, the lowest of such Market Quotations shall be the lowest Market Quotation of such Market Quotations expressed as a positive number or, if any of such Market Quotations is expressed as a negative number, the Market Quotation expressed as a negative number with the largest absolute value).

(E)

Party B undertakes to use its reasonable efforts to obtain at least one Market Quotation before the Latest Settlement Amount Determination Day.  Party B will be deemed to have discharged its obligations under the preceding sentence if it requests Party A to obtain Market Quotations, where such request is made in writing within two Local Business Days after the day on which the Early Termination Date is designated.  If Party B requests Party A in writing to obtain Market Quotations, Party A shall use its reasonable efforts to do so before the Latest Settlement Amount Determination Day.

(F)

Any amount calculated as being due in respect of an Early Termination Date will be payable in accordance with Section 6(d)(ii), provided that if such payment is owed to Party B, it will be payable on the day that notice of the amount payable is given to Party A.

(G)

If the Settlement Amount is not determined by reference to a Market Quotation that has been accepted by Party B and the Settlement Amount is a negative number, Section 6(e)(i)(3) of this Agreement shall be deleted in its entirety and replaced with the following:

Second Method and Market Quotation. If Second Method and Market Quotation apply, (1) Party B shall pay to Party A an amount equal to the absolute value of the Settlement Amount in respect of the Terminated Transactions, (2) Party B shall pay to Party A the Termination Currency Equivalent of the Unpaid Amounts owing to Party A and (3) Party A shall pay to Party B the Termination Currency Equivalent of the Unpaid Amounts owing to Party B, provided that, (i) the amounts payable under (1), (2) and (3) shall be subject to netting in accordance with Section 2(c) of this Agreement and (ii) notwithstanding any other provision of this Agreement, any amount payable by Party A under (3) shall not be netted off against any amount payable by Party B under (1).

(m)

“Termination Currency” means United States Dollars.

(n)

Additional Termination Events.  Each of the following shall be an Additional Termination Event:  

(i)

First Rating Trigger Event.  A First Rating Trigger Event (as defined in Part 5(i)) has occurred, and Party A has not, within the period of time prescribed, complied with Part 5(i)(ii) below.  For purposes of this Additional Termination Event, Party A shall be the sole Affected Party.

(ii)

S&P Second Rating Trigger Event.  A Second Rating Trigger Event (as defined in Part 5(i)) with respect to S&P has occurred, and Party A has not, within 10 Business Days after such event, complied with the requirements of Part 5(i)(iii) below.  For purposes of this Additional Termination Event, Party A shall be the sole Affected Party.

(iii)

Moody’s Second Rating Trigger Event.  (A) A Second Rating Trigger Event with respect to Moody’s has occurred, and 30 or more Local Business Days have elapsed and (B) (i) at least one Eligible Replacement (as defined in Part 5(i)) has made a Firm Offer to be the transferee of a transfer to be made in accordance with Part 5(i)(iii) below and/or (ii) at least one entity with the Acceptable Ratings (as defined in Part 5(i)) has made a Firm Offer to provide an Eligible Guarantee in respect of all of Party A’s present and future obligations under this Agreement.

Rating Agency Downgrade.

(i)

For purposes of this Part 5(i), the following definitions apply:

An entity has “Acceptable Ratings” if (x) its short-term unsecured and unsubordinated debt is rated at least “A-1” by S&P (or, if it does not have a short-term unsecured and unsubordinated debt rating from S&P,  its long-term unsecured and unsubordinated debt is rated at least “A+” by S&P), and (y) its long-term unsecured and unsubordinated debt is rated at least “A3” or its short-term unsecured and unsubordinated debt is rated at least “Prime-2” (or if it does not have a short-term unsecured and unsubordinated debt rating from Moody’s, its long-term unsecured and unsubordinated debt is rated at least “A3”).

“Eligible Guarantee” means an unconditional and irrevocable guarantee that is provided by a guarantor with Acceptable Ratings as principal debtor rather than surety and is directly enforceable by Party B, where either (A) a law firm has given a legal opinion confirming that none of the guarantor’s payments to Party B under such guarantee will be subject to withholding for tax or (B) such guarantee provides that, in the event that any of such guarantor’s payments to Party B are subject to withholding for tax, such guarantor is required to pay such additional amount as is necessary to ensure that the net amount actually received by Party B (free and clear of any withholding tax) will equal the full amount Party B would have received had no such withholding been required.

“Eligible Replacement” means an entity (A) with the Acceptable Ratings or (B) whose present and future obligations owing to Party B are guaranteed pursuant to an Eligible Guarantee.

A “First Rating Trigger Event” shall occur with respect to Party A (or any applicable credit support provider), if (x) its short-term unsecured and unsubordinated debt ceases to be rated at least “A-1” by S&P (or, if Party A does not have a short-term unsecured and unsubordinated debt rating from S&P,  its long-term unsecured and unsubordinated debt ceases to be rated at least “A+” by S&P), or (y)(a) its long-term unsecured and unsubordinated debt ceases to be rated at least “A2” by Moody’s or its short-term unsecured and unsubordinated debt ceases to be rated at least “Prime-1” by Moody’s, or (b) if it does not have a short-term unsecured and unsubordinated debt rating from Moody’s, its long-term unsecured and unsubordinated debt ceases to be rated at least “A1” by Moody’s.

“Rating Agency Condition” means, with respect to any particular proposed act or omission to act hereunder, that the party acting or failing to act must consult with each of the Rating Agencies then providing a rating of the Certificates and receive from each such Rating Agency a prior written confirmation that the proposed action or inaction would not cause a downgrade or withdrawal of the then-current rating of the Certificates.

A “Second Rating Trigger Event” shall occur with respect to Party A (or any applicable credit support provider), if (A) Party A’s long-term unsecured and unsubordinated debt ceases to be rated at least “BBB-” or  Party A’s short-term unsecured and unsubordinated debt ceases to be rated at least “A-3” or is withdrawn by S&P or (B) Party A’s long-term unsecured and unsubordinated debt ceases to be rated at least “A3” or Party A’s short-term unsecured and unsubordinated debt ceases to be rated at least “Prime-2” (or if Party A does not have a short-term unsecured and unsubordinated debt rating from Moody’s, its long-term unsecured and unsubordinated debt ceases to be rated at least “A3”).

(ii)

If a First Rating Trigger Event occurs with respect to Party A (or any applicable Credit Support Provider), then (unless, within 30 days of such First Rating Trigger Event, each of Standard and Poor’s, a Division of McGraw-Hill Companies, Inc. (“S&P”), and Moody’s Investors Service, Inc. (“Moody’s) (each a “Rating Agency”) has reconfirmed its rating of the Certificates which was in effect immediately prior to such First Rating Trigger Event) Party A shall, within 30 days of such First Rating Trigger Event, at its own expense, (A) obtain an Eligible Guarantee in respect of all of Party A’s present and future obligations under this Agreement, subject to the Rating Agency Condition (B) transfer all or substantially all of its rights and obligations with respect to this Agreement to an Eligible Replacement (provided that Party B shall determine in its sole discretion, acting in a commercially reasonable manner, whether or not a transfer relates to all or substantially all of Party A’s rights and obligations under this Agreement), subject to the Rating Agency Condition or (C) post collateral in accordance with the Credit Support Annex to this Agreement, subject to the Rating Agency Condition in respect of S&P only.  

(iii)

If a Second Rating Trigger Event occurs with respect to Party A (or any applicable Credit Support Provider), then Party A will at its own cost use commercially reasonable efforts to, as soon as reasonably practicable (or, in the event of a Second Rating Trigger Event with respect to S&P, within ten Business Days) either (A) obtain an Eligible Guarantee in respect of all of Party A’s present and future obligations under this Agreement, subject to the Rating Agency Condition, or (B) transfer all or substantially all of its rights and obligations with respect to this Agreement to an Eligible Replacement (provided that Party B shall determine in its sole discretion, acting in a commercially reasonable manner, whether or not a transfer relates to all or substantially all of Party A’s rights and obligations under this Agreement), subject to the Rating Agency Condition.

(ii)

Subject to the provisions of clause (iii) below, and so long as there are reporting obligations with respect to this Transaction under Regulation AB, if the Depositor determines, reasonably and in good faith, that the aggregate significance percentage of this Agreement has increased to nine (9) percent, then the Depositor or Party B may request from Party A (such request, a “Disclosure Request”) on a Business Day after the date of such determination the same information set forth in Item 1115(b) of Regulation AB (such requested information, subject to the last sentence of this paragraph, the “Financial Disclosure”) that would have been required if the significance percentage had in fact increased to ten (10) percent.  Party B, the Depositor or any of its agents shall provide Party A with the calculations and any other information reasonably requested by Party A with respect to the Depositor’s determination that led to the Disclosure Request.  The parties hereto further agree that the Financial Disclosure provided to meet the Disclosure Request may be, solely at Party A’s option, either the information set forth in Item 1115(b)(1) or Item 1115(b)(2) of Regulation AB.

(iii)

So long as there are reporting obligations with respect to this Transaction under the 1934 Act, if the Depositor determines, reasonably and in good faith, that the aggregate significance percentage of this Agreement has increased to nineteen (19) percent, then the Depositor or Party B may make a Disclosure Request to Party A on a Business Day after the date of such determination for the Financial Disclosure that would have been required if the significance percentage had in fact increased to twenty (20) percent.  Party B, the Depositor or any of its agents shall provide Party A with the calculations and any other information reasonably requested by Party A with respect to the Depositor’s determination that led to the Disclosure Request.

(iv)

Upon the occurrence of a Disclosure Request, Party A, at its own expense, shall (i) provide the Depositor and Party B with the Financial Disclosure, (ii) subject to Rating Agency Condition, secure an Eligible Replacement to replace Party A as party to this Agreement on terms substantially similar to this Agreement which entity is able to, and does, provide the Financial Disclosure or (iii) subject to Rating Agency Condition, obtain a guaranty of Party A’s obligations under this Agreement from an affiliate of Party A that is able to provide the Financial Disclosure, such that disclosure provided in respect of the affiliate will satisfy any disclosure requirements applicable to Party A, and cause such affiliate to provide Financial Disclosure.  For purposes of clause (ii) above, the parties agree that National Westminster Bank Plc (“NatWest”) shall be an acceptable replacement for Party A, so long as NatWest satisfies the conditions specified in such clause (ii).  If permitted by Regulation AB, any required Financial Disclosure may be provided by incorporation by reference from reports filed pursuant to the 1934 Act.   

(v)

Party A agrees that, if it responds to a Disclosure Request by providing Financial Disclosure, then, for so long as the Depositor has reporting obligations under the 1934 Act with respect to this Transaction, it will provide any interim updates to Financial Disclosure within 5 Business Days following the availability thereof (but in no event more than six months after the end of Party A’s fiscal year for any annual update).  If permitted by Regulation AB, any such update may be provided by incorporation by reference from reports filed pursuant to the 1934 Act.

(k)

Severability.  If any term, provision, covenant, or condition of the Agreement, or the application thereof to any other party or circumstance, shall be held invalid or unenforceable (in whole or in part) for any reason, the remaining terms, provisions, covenants, and conditions hereof shall continue in full force and effect as if the Agreement has been executed with the invalid or unenforceable provision portion eliminated, so long as the Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter of the Agreement and the deletion of such portion of the Agreement will not substantially impair the respective benefits or expectations of the parties.  The parties shall endeavor to engage in good faith negotiations to replace any invalid or unenforceable term, provision, covenant or conditions with a valid or enforceable term, provision, covenant or condition, the economic effect of which comes as close as possible to that of the invalid or unenforceable term, provision, covenant or condition.

(ii) If an Eligible Replacement has made a Firm Offer (which remains an offer that will become legally binding  upon acceptance by Party B) to be the transferee pursuant to a Permitted Transfer, Party B shall, at Party A’s written request and at Party A’s expense, take any reasonable steps required to be taken by Party B to effect such transfer.

(p)

Non-Recourse.  Notwithstanding any provision herein, the obligations of Party B hereunder are limited recourse obligations of Party B, payable solely from the Supplemental Interest Trust and the proceeds thereof, in accordance with the terms of the Pooling Agreement.
