MISCELLANEOUS

Section 8.1 Survival. The representations, warranties, covenants and agreements contained in this Agreement shall survive the applicable Funding Date and delivery of the Mortgage Loans to Purchaser and shall not terminate, notwithstanding the termination of the Agreement, any restrictive or qualified endorsement on any Mortgage Note or Purchaser’s examination or failure to examine any Mortgage File, Purchaser’s approval of any Mortgage Loan for purchase or Purchaser’s purchase of any Mortgage Loan.

Section 8.2 Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. However, by its terms the Seller Guide may be amended or supplemented by Purchaser from time to time in Purchaser’s sole and absolute discretion. Any such amendment or supplement to the Seller Guide shall be in writing and binding upon the parties hereto on and after the effective date specified herein. If Seller registers, locks or delivers a Mortgage Loan after receiving notice of a proposed amendment, Seller shall be deemed to have agreed to such amendment.

Section 8.3 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which shall be considered one and the same instrument.

Section 8.4 Entire Agreement. This Agreement, the Seller Guide and any Commitment Letters executed in connection herewith contain the entire agreement between the parties and supersede all prior agreements, arrangements and understandings relating to the subject matter thereof. There are no written or oral agreements, understandings, representations or warranties between the parties other than those set forth herein and therein.

Section 8.5 Rights Cumulative; Waivers. The rights of each of the parties under this Agreement are cumulative, may be exercised as often as any party considers appropriate and are in addition to each such party’s rights under any other documents executed between the parties or, except as otherwise modified herein, under law. The rights of each of the parties hereunder shall not be capable of being waived or varied otherwise than by an express waiver or variation in writing. Any failure to exercise or any delay in exercising any of such rights shall not operate as a waiver or variation of that or any other such right. Any defective or partial exercise of any of such rights shall not preclude any other or further exercise of that or any other such right. No act or course of conduct or negotiation on the part of any party shall in any way preclude such party from exercising any such right or constitute a suspension or any variation of any such right. At any time prior to any sale, Seller, on the one hand, and Purchaser, on the other may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto, (b) waive any inaccuracies in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto or (c) waive compliance with any of the agreements of the other party contained herein or satisfaction of any of the conditions to the performance of its obligations contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party granting the extension or waiver.

Section 8.6 Section Headings. The section and paragraph headings contained in this Agreement are for reference purposes only and shall not in any way affect the meaning or interpretation of the Agreement.

All notices and other communications hereunder shall be in writing (including a writing delivered by facsimile transmission) and shall be deemed to have been duly given (a) when delivered, if sent by registered or certified mail (return receipt requested), (b) when delivered, if delivered by facsimile transmission, personally or by telecopy, or (c) on the second following business day, if sent by United States Express Mail or overnight courier, in each case to the parties at the addresses set forth on the signature page of this Agreement (or at such other addresses or facsimile number as shall be specified by like notice).

Section 8.8 Governing Law. This Agreement shall be governed by, construed and enforced in accordance with the laws of the State of California without reference to the choice of law principles thereof.

Section 8.9 Severability. In the case any provision in this Agreement shall be found by a court of competent jurisdiction to be invalid, illegal or unenforceable, such provision shall be construed and enforced as if it had been more narrowly drawn so as not to be invalid, illegal or unenforceable, and the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof. If the invalidity of any part, provision, representation or warranty of this Agreement shall deprive any party of the economic benefit intended to be conferred by this Agreement, the parties shall negotiate, in good faith, to develop a structure the economic effect of which is as close as possible to the economic effect of the Agreement without regard to such invalidity.

Section 8.10 Successors and Assigns. This Agreement shall be binding upon the parties hereto and their respective successors and assigns and shall inure to the benefit of the parties hereto and their respective permitted successors and assigns. Seller shall not assign this Agreement nor any rights hereunder, including, without limitation, the right to receive compensation or money due hereunder, without the prior express written consent of Purchaser. Seller shall not delegate any duty hereunder without the prior express written consent of Purchaser.

Section 8.11 Reproduction of Documents. This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications which may hereafter be executed, (b) documents received by any party at the closing, and (c) financial statements, certificates and other information previously or hereafter furnished, may be reproduced by any photographic, photostatic, microfilm, micro-card, miniature photographic or other similar process. The parties agree that any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding, whether or not the original is in existence and whether or not such reproduction was made by a party in the regular course of business, and that any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence.

Section 8.12 Relationship of Parties. The relationship between the parties is an independent contractor relationship, and Seller is not, and shall not represent to third parties that it is acting as an agent for and on behalf of Purchaser. Notwithstanding the foregoing, Seller acknowledges that it has a contractual duty to Purchaser to deliver eligible Mortgage Loans for sale and assignment to Purchaser.

Section 8.13 Governing Agreement. In case of any inconsistency between this Agreement and the Seller Guide, the terms and provisions of the Seller Guide shall control. In the case of any inconsistency between either: (a) this Agreement and any Commitment Letter; or (b) the Seller Guide and any Commitment Letter, the terms and provisions of such Commitment Letter shall control.

Section 8.14 Arbitration. In the event a dispute arises regarding this Agreement, the Parties agree that such dispute shall be submitted to final and binding arbitration before the American Arbitration Association (hereinafter “AAA”). The Parties to this Agreement will initially agree on the arbitrator to hear the dispute. If the Parties cannot agree, AAA will appoint an arbitrator for such purpose. The arbitration will proceed in accordance with the rules of the AAA unless all Parties agree to a different procedure. The Parties shall share equally in the costs of the arbitration, except that each Party will be responsible for its own attorneys’ fees and costs. All such arbitration shall be conducted in the city nearest Purchaser’s home office. Any Party who fails to submit to binding arbitration following a lawful demand by the other Party shall bear all costs and expenses, including reasonable attorneys’ fees (including those incurred in any trial, bankruptcy proceeding or an appeal) incurred by the other Party in obtaining a stay of any pending judicial proceeding and compelling arbitration of any dispute. THE PARTIES UNDERSTAND THAT BY THIS AGREEMENT THEY HAVE DECIDED THAT THEIR DISPUTE SHALL BE RESOLVED BY BINDING ARBITRATION RATHER THAN IN COURT, AND ONCE DECIDED BY ARBITRATION NO DISPUTE CAN LATER BE BROUGHT, FILED OR PURSUED IN COURT.

IN WITNESS WHEREOF, the Seller and the Purchaser have caused their names to be signed hereto by their respective officers thereunto duly authorized as of the date first above written.
