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, execute such documentation provided to it as is reasonably deemed necessary by Party A 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, officers, agents, employees, shareholders or affiliates of 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 Supplemental Interest Trust and the proceeds thereof, any claims against or obligations of Party B under this 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 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. (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. (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. 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 U.S. Bank National Association not in its individual capacity, but solely as Supplemental Interest Trust Trustee of the RASC Series 2007-EMX1 Supplemental Interest Trust Trustee under the Pooling and Servicing Agreement in the exercise of the powers and authority conferred and invested in it thereunder; (b) U.S. Bank 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 is made and intended not as personal representations of U.S. Bank but is made and intended for the purpose of binding only the Supplemental Interest Trust; and (d) under no circumstances shall U.S. Bank 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.

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.
