Party A and Party B hereby agree that the terms of the Indemnification and Disclosure Agreement, dated as of May 10, 2007, (the “Indemnification and Disclosure Agreement”), between Washington Mutual Bank (“Sponsor”) and Barclays Bank PLC (the “Derivative Provider”) shall be incorporated by reference into this Agreement and Party B shall be an express third party beneficiary of the Indemnification and Disclosure Agreement. A copy of the Indemnification and Disclosure Agreement is annexed hereto at Annex B.

(f) Transfers.

(i) Section 7 is hereby amended to read in its entirety as follows:

“Except with respect to any Permitted Transfer pursuant to Section 6(b)(ii), Part 5(d), the Indemnification and Disclosure Agreement, or the succeeding sentence, neither Party A nor Party B is permitted to assign, novate or transfer (whether by way of security or otherwise) as a whole or in part any of its rights, obligations or interests under the Agreement or any Transaction unless (a) the prior written consent of the other party is obtained (such consent not to be unreasonably withheld), and (b) the Rating Agency Condition has been satisfied with respect to S&P and Fitch, except that:

(a) a party may make such a transfer of this Agreement pursuant to a consolidation or amalgamation with, or merger with or into, or transfer of all or substantially all its assets to, another entity (but without prejudice to any other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any amount payable to it from a Defaulting Party under Section 6(e).

At any time at which no Relevant Entity has credit ratings at least equal to the Approved Ratings Threshold, Party A may make a Permitted Transfer.”

(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.

(g) Non-Recourse. Party A acknowledges and agree that, notwithstanding any provision in this Agreement to the contrary, 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 priority of payments and other terms of the Pooling and Servicing Agreement and that Party A will not have any recourse to any of the directors, trustees, officers, employees, shareholders or affiliates of the Party B with respect to any claims, losses, damages, liabilities, indemnities or other obligations in connection with any transactions contemplated hereby. In the event that the Supplemental Interest Trust and the proceeds thereof, should be insufficient to satisfy all claims outstanding and following the realization of the account held by the Supplemental Interest Trust and the proceeds thereof, any claims against or obligations of Party B under the ISDA Master Agreement or any other confirmation thereunder still outstanding shall be extinguished and thereafter not revive. The Supplemental Interest Trust Trustee shall not have liability for any failure or delay in making a payment hereunder to Party A due to any failure or delay in receiving amounts in the account held by the Supplemental Interest Trust from the Trust created pursuant to the Pooling and Servicing Agreement. This provision will survive the termination of this Agreement.

(h) Timing of Payments by Party B upon Early Termination. Notwithstanding anything to the contrary in Section 6(d)(ii), to the extent that all or a portion (in either case, the “Unfunded Amount”) of any amount that is calculated as being due in respect of any Early Termination Date under Section 6(e) from Party B to Party A will be paid by Party B from amounts other than any upfront payment paid to Party B by an Eligible Replacement that has entered a Replacement Transaction with Party B, then such Unfunded Amount shall be due on the next subsequent Distribution Date following the date on which the payment would have been payable as determined in accordance with Section 6(d)(ii), and on any subsequent Distribution Dates until paid in full (or if such Early Termination Date is the final Distribution Date, on such final Distribution Date); provided, however, that if the date on which the payment would have been payable as determined in accordance with Section 6(d)(ii) is a Distribution Date, such payment will be payable on such Distribution Date. For the avoidance of doubt, interest on any payment due in respect of an Early Termination Date under Section 6(e) will in all events accrue interest from (and including) such Early Termination Date to (but excluding) the date on which the relevant payment is made.

(i) Rating Agency Notifications. Notwithstanding any other provision of this Agreement, no Early Termination Date shall be effectively designated hereunder by Party B and no transfer of any rights or obligations under this Agreement shall be made by either party unless each Swap Rating Agency has been given prior written notice of such designation or transfer.

(j) No Set-off. Except as expressly provided for in Section 2(c), Section 6 or Part 1(f)(i)(D) hereof, and notwithstanding any other provision of this Agreement or any other existing or future agreement, each party irrevocably waives any and all rights it may have to set off, net, recoup or otherwise withhold or suspend or condition payment or performance of any obligation between it and the other party hereunder against any obligation between it and the other party under any other agreements. Section 6(e) shall be amended by deleting the following sentence: “The amount, if any, payable in respect of an Early Termination Date and determined pursuant to this Section will be subject to any Set-off.”.

(k) Amendment. Notwithstanding any provision to the contrary in this Agreement, no amendment of either this Agreement or any Transaction under this Agreement shall be permitted by either party unless each of the Swap Rating Agencies has been provided prior written notice of the same and such amendment satisfies the Rating Agency Condition with respect to S&P and Fitch.

(l) Notice of Certain Events or Circumstances. Each Party agrees, upon learning of the occurrence or existence of any event or condition that constitutes (or that with the giving of notice or passage of time or both would constitute) an Event of Default or Termination Event with respect to such party, promptly to give the other Party and to each Swap Rating Agency notice of such event or condition; provided that failure to provide notice of such event or condition pursuant to this Part 5(l) shall not constitute an Event of Default or a Termination Event.

(m) Proceedings. No Relevant Entity shall institute against, or cause any other person to institute against, or join any other person in instituting against Party B, the Supplemental Interest Trust, or the trust formed pursuant to the Pooling and Servicing Agreement, in any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or other proceedings under any federal or state bankruptcy or similar law for a period of one year (or, if longer, the applicable preference period) and one day following payment in full of the Certificates and any Notes; provided, however, that nothing will preclude, or be deemed to stop, Party A (i) from taking any action prior to the expiration of the aforementioned one year and one day period, or if longer the applicable preference period then in effect, in (A) any case or proceeding voluntarily filed or commenced by Party B or (B) any involuntary insolvency proceeding commenced by a Person other than Party A, or (ii) from commencing against Party B or any of the Collateral any legal action which is not a bankruptcy, reorganization, arrangement, insolvency, moratorium, liquidation or similar proceeding. This provision will survive the termination of this Agreement.

(n) Supplemental Interest Trust Trustee Liability Limitations. It is expressly understood and agreed by the parties hereto that (a) this Agreement is executed by Citibank, N.A. not in its individual capacity, but solely as Supplemental Interest Trust Trustee on behalf of the Supplemental Interest Trust in the exercise of the powers and authority conferred and invested in it under the Pooling and Servicing Agreement; (b) Citibank, N.A. has been directed pursuant to the Pooling and Servicing Agreement to enter into this Agreement and to perform its obligations hereunder; (c) each of the representations, undertakings and agreements herein made on behalf of the Supplemental Interest Trust or on the part of Party B is made and intended not as personal representations of Citibank, N.A. but is made and intended for the purpose of binding only the Supplemental Interest Trust; and (d) under no circumstances shall Citibank, N.A. in its individual capacity be personally liable for any payments hereunder or for the breach or failure of any obligation, representation, warranty or covenant made or undertaken under this Agreement, as to all of which recourse shall be had solely to the assets of the Supplemental Interest Trust in accordance with the terms of the Pooling and Servicing Agreement.

(o) 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) in any respect, 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.

(p) Agent for Party B. Party A acknowledges that Party B has appointed the Supplemental Interest Trust Trustee as its agent under the Pooling and Servicing Agreement to carry out certain functions on behalf of Party B, and that the Supplemental Interest Trust Trustee shall be entitled to give notices and to perform and satisfy the obligations of Party B hereunder on behalf of Party B.

(q) 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 any corresponding payment payable by 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.

(r) Consent to Recording. Each party hereto consents to the monitoring or recording, at any time and from time to time, by the other party of any and all communications between trading, marketing, and operations personnel of the parties and their Affiliates, waives any further notice of such monitoring or recording, and agrees to notify such personnel of such monitoring or recording.

(s) Waiver of Jury Trial. Each party waives any right it may have to a trial by jury in respect of any in respect of any suit, action or proceeding relating to this Agreement or any Credit Support Document.

(t) Form of ISDA Master Agreement. Party A and Party B hereby agree that the text of the body of the ISDA Master Agreement is intended to be the printed form of the ISDA Master Agreement (Multicurrency – Crossborder) as published and copyrighted in 1992 by the International Swaps and Derivatives Association, Inc.

(v) Additional representations.

Party A represents to Party B on the date on which Party A enters into each Transaction this Agreement that it is entering into the Agreement and the Transaction as principal and not as agent of any person.

(w) Acknowledgements.

(i) Substantial financial transactions. Each party hereto is hereby advised and acknowledges as of the date hereof that the other party has engaged in (or refrained from engaging in) substantial financial transactions and has taken (or refrained from taking) other material actions in reliance upon the entry by the parties into the Transaction being entered into on the terms and conditions set forth herein and in the Pooling and Servicing Agreement relating to such Transaction, as applicable. This paragraph shall be deemed repeated on the trade date of each Transaction.

(ii) Bankruptcy Code.
