(ii) Subject to Part 5(z), Party A may (at its own cost) transfer all or substantially all of its rights and obligations with respect to this Agreement to any other entity (a “Transferee”) that is an Eligible Replacement through an assignment and assumption agreement or similar agreement in form and substance reasonably satisfactory to Party B; provided that (A) 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, (B) the Transferee, as of the date of the transfer, must not, as a result thereof, be required to withhold or deduct on account of Tax under this Agreement unless such Transferee will be required to make payments of additional amounts pursuant to Section 2(d)(i)(4) of this Agreement with respect of such Tax, (C) the transfer to the Transferee must not lead to a Termination Event or Event of Default occurring with respect to this Agreement, and (D) the Transferee, as of the date of the transfer, must enter into a new indemnification and disclosure agreement with substantially the same terms as the existing IDA; provided that satisfaction of the Rating Agency Condition will be required unless such transfer is in connection with the assignment and assumption of this Agreement without modification of its terms, other than the following terms: party name, dates relevant to the effective date of such transfer, tax representations (provided that the representations in Part 2(a) are not modified) and any other representations regarding the status of the Transferee of the type included in Section (c) of this Part 5 and notice information (in which case, Party A shall provide prior written notice to Rating Agencies with respect thereto). Following such transfer, all references to Party A shall be deemed to be references to the Transferee.

(iii) If an entity has made a Firm Offer (which remains capable of becoming legally binding upon acceptance) to be the transferee of a transfer to be made in accordance with Part 5(e)(ii) above, Party B shall (at Party A’s cost) at Party A’s written request, take any reasonable steps required to be taken by it to effect such transfer.

(iv) Except as specified otherwise in the documentation evidencing a transfer, a transfer of all the obligations of Party A made in compliance with this Part 5(e) will constitute an acceptance and assumption of such obligations (and any related interests so transferred) by the Transferee, a novation of the transferee in place of Party A with respect to such obligations (and any related interests so transferred), and a release and discharge by Party B of Party A from, and an agreement by Party B not to make any claim for payment, liability, or otherwise against Party A with respect to, such obligations from and after the effective date of the transfer.

(v) In addition, Party A may transfer this Agreement without the prior written consent of Party B but with prior written notice to S&P, Moody’s, Fitch and the Supplemental Interest Trust Trustee, to an Affiliate of Party A if: (i) such Affiliate has the First Trigger Required Ratings or has furnished an Eligible Guarantee provided by a guarantor that satisfies the Hedge Counterparty Ratings Requirement, (ii) the transfer to such Affiliate does not lead to a Termination Event or Event of Default occurring with respect to this Agreement, (iii) as of the date of the transfer, such Affiliate assumes all continuing obligations of Party A, if any, under the IDA, and (iv) as of the date of the transfer, such Affiliate will not be required to withhold or deduct on account of a Tax from any payments under this Agreement unless such Affiliate will be required to make payments of additional amounts pursuant to Section 2(d)(i)(4) of this Agreement with respect of such Tax; provided that satisfaction of the Rating Agency Condition will be required unless such transfer is in connection with the assignment and assumption of this Agreement by such an Affiliate without modification of its terms, other than the following terms: party name, dates relevant to the effective date of such transfer, tax representations (provided that the representations in Part 2(a) are not modified) and any other representations regarding the status of such an Affiliate of the type included in Section (c) of this Part 5 and notice information (in which case, Party A shall provide written notice to Rating Agencies with respect thereto).

(p) Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to this Agreement or any Credit Support Document. Each party certifies (i) that no representative, agent or attorney of the other party or any Credit Support Provider has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Agreement and provide for any Credit Support Document, as applicable, by, among other things, the mutual waivers and certifications in this Section.

(r) Independent Reliance. The parties agree to amend Section 3 of this Agreement by the addition of the following provision at the end thereof and marked as subsection (g):

(g) Independent Reliance. Party A is entering into this Agreement and will enter into each Transaction in reliance upon such tax, accounting, regulatory, legal, and financial advice as it deems necessary and not upon any view expressed by the other party. Party B is entering into this Agreement and will enter into each Transaction in reliance upon the direction of the Depositor and not upon any view expressed by the other party.

(s) Escrow Payments. If (whether by reason of the time difference between the cities in which payments are to be made or otherwise) it is not possible for simultaneous payments to be made on any date on which both parties are required to make payments hereunder, either party may at its option and in its sole discretion notify the other party that payments on that date are to be made in escrow. In this case deposit of the payment due earlier on that date shall be made by 2:00 pm (local time at the place for the earlier payment) on that date with an escrow agent selected by the notifying party, accompanied by irrevocable payment instructions (i) to release the deposited payment to the intended recipient upon receipt by the escrow agent of the required deposit of the corresponding payment from the other party on the same date accompanied by irrevocable payment instructions to the same effect or (ii) if the required deposit of the corresponding payment is not made on that same date, to return the payment deposited to the party that paid it into escrow. The party that elects to have payments made in escrow shall pay all costs of the escrow arrangements.

(t) Method of Notice. Section 12(a)(ii) of this Agreement is deleted in its entirety.

(u) USA PATRIOT Act Notice. Party A hereby notifies Party B that pursuant to the requirements of the USA Patriot Act (Title III of Pub.

(v) Severability. If any term, provision, covenant, or condition of this Agreement, or the application thereof to any party or circumstance, shall be held to be 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 this Agreement had been executed with the invalid or unenforceable portion eliminated, so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter of this Agreement and the deletion of such portion of this Agreement will not substantially impair the respective benefits or expectations of the parties; provided, however, that this severability provision shall not be applicable if any provision of Section 2, 5, 6, or 13 (or any definition or provision in Section 14 to the extent it relates to, or is used in or in connection with any such Section) shall be so held to be invalid or unenforceable.

The parties shall endeavor to engage in good faith negotiations to replace any invalid or unenforceable term, provision, covenant or condition 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.

(w) Tax.

(i) Indemnifiable Tax. Notwithstanding the definition of “Indemnifiable Tax” in Section 14 of this Agreement, in relation to payments by Party A, any Tax shall be an Indemnifiable Tax and, in relation to payments by Party B, no Tax shall be an Indemnifiable Tax.

(ii) Gross Up. Section 2(d)(i)(4) of this Agreement shall not apply to Party B as X, and Section 2(d)(ii) shall not apply to Party B as Y, in each case such that Party B shall not be required to pay any additional amounts referred to therein.

(x) Limited Recourse. The liability of Party B under this Agreement is limited in recourse to the assets of the Supplemental Interest Trust, and to distributions of interest proceeds and principal proceeds thereon applied in accordance with the terms of the PSA. Upon application of and exhaustion of all of the assets of the Supplemental Interest Trust (and proceeds thereof) in accordance with the PSA, Party A shall not be entitled to take any further steps against Party B to recover any sums due but still unpaid hereunder or thereunder, all claims in respect of which shall be extinguished. Notwithstanding the foregoing or anything herein to the contrary, Party A shall not be precluded from declaring an Event of Default or from exercising any other right or remedy as set forth in this Agreement or the PSA.

(y) Calculations. Notwithstanding Section 6 of this Agreement, so long as Party A is (A) the Affected Party in respect of an Additional Termination Event or a Tax Event Upon Merger or (B) the Defaulting Party in respect of any Event of Default, paragraphs (i) to (vi) below shall apply:

(i) 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, 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 terms substantially the same as those of this Agreement (save for the exclusion of provisions relating to Transactions that are not Terminated Transactions).

(ii) 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) equal to the Termination Currency Equivalent of the amount (whether positive or negative) of any Market Quotation for the relevant Terminated Transaction or group of Terminated Transactions that is accepted by Party B so as to become legally binding, provided that:

(a) If, on 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 (but in either case no later than the Early Termination Date) (such day the “Latest Settlement Amount Determination Day”), no Market Quotation for the relevant Terminated Transaction or group of Terminated Transactions has been accepted by Party B so as to become legally binding and one or more Market Quotations have been made and remain capable of becoming legally binding upon acceptance, the Settlement Amount shall equal the Termination Currency Equivalent of the amount (whether positive or negative) of the lowest of such Market Quotations and

(b) If, on the Latest Settlement Amount Determination Day, no Market Quotation for the relevant Terminated Transaction or group of Terminated Transactions is accepted by Party B so as to become legally binding and no Market Quotations have been made and remain capable of becoming legally binding upon acceptance, the Settlement Amount shall equal 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.

(iii) For the purpose of paragraph (4) of the definition of Market Quotation, Party B shall determine in its sole discretion, acting in a 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); provided, however, that notwithstanding the provisions of this Part 5(y), nothing in this Agreement shall preclude Party A from obtaining Market Quotations.

(iv) 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.

(v) 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.

(vi) If 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 (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).

(z) Rating Agency Notifications. Notwithstanding any other provision of this Agreement, this Agreement shall not be amended, no Early Termination Date shall be effectively designated by Party B, and no transfer of any rights or obligations under this Agreement shall be made (other than a transfer of all of Party A’s rights and obligations with respect to this Agreement in accordance with Part 5(e)(ii) above) unless Moody’s has been given prior written notice of such amendment, designation or transfer.

(i) Delivery Amount, Return Amount and Credit Support Amount.

(A) “Delivery Amount” has the meaning specified in Paragraph 3(a) except that the words “upon a demand made by the Secured Party on or promptly following a Valuation Date” shall be deleted and replaced by the words “on each Valuation Date commencing no later than the Local Business day next following the Valuation Date falling, in the case of a First Trigger Failure Condition, on the 30th calendar day or the next day thereafter that is a Local Business Day (or, in the case of a First Trigger Failure Condition that relates solely to a failure to satisfy the Moody’s component of the First Trigger Required Ratings, the 30th Local Business Day), or, in the case of a Second Trigger Failure Condition, promptly, after publication by the applicable Rating Agency of the applicable change in rating”.

(B) "Return Amount" has the meaning specified in Paragraph 3(b).

(ii) Eligible Credit Support. The following items will qualify as “Eligible Collateral” for the Party A, with the applicable Valuation Percentage indicated in the following table.
