9. Indemnification and Contribution. The Company agrees with the Underwriters that:

(a) The Company indemnifies and holds harmless the Underwriters, the Underwriters’ officers, directors and partners, and each Person who controls the Underwriters within the meaning of either the 1933 Act or the 1934 Act against any and all losses, claims, damages or liabilities, joint or several, to which the Underwriters may become subject under the 1933 Act, the 1934 Act, or other federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (x) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment thereof, or the omission or alleged omission to state in the Registration Statement or any amendment thereof a material fact required to be stated therein or necessary to make the statements therein not misleading, or (y) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Pricing Free Writing Prospectus or the Final Prospectus, or the omission or alleged omission to state in the Base Prospectus, the Pricing Free Writing Prospectus, the Final Prospectus or in any amendment or supplement to any of them, or the Issuer Information, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and agrees to reimburse for any legal or other expenses reasonably incurred by the Underwriters, the Underwriters’ respective officers and directors and each such controlling person in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, expense, damage or liability arises out of or is based upon an untrue statement or omission, or alleged untrue statement or omission, made in any of such documents (x) under the heading “Yield, Prepayment and Maturity Considerations—Weighted Average Lives,” the tables regarding assumed mortgage loan characteristics and the tables entitled “Percent of Original Certificate Principal Balance Outstanding” (collectively, the “Excluded Information”); (y) in reliance upon and in conformity with any Underwriters’ Information or (z) in any Derived Information in any Free Writing Prospectus, except in the case of clause (x) or (z) to the extent that any untrue statement or omission or alleged untrue statement or alleged omission therein results (or is alleged to have resulted) from an error or material omission in the information in the Pricing Free Writing Prospectus or the Final Prospectus for which the Company is responsible or concerning the characteristics of the Mortgage Loans furnished by the Seller or the Company, as applicable, to the Underwriters for use in the preparation of any Excluded Information in any Free Writing Prospectus (any such information, the “Pool Information”), which error was not superseded or corrected by the delivery to the Underwriters of corrected written or electronic information, or for which the Company did not provide timely written notice of such error to the Underwriters (any such uncorrected Pool information, a “Pool Error”); and, provided further that the Company shall not be liable in any such case to the extent that any such loss, claim, expense, damage or liability arises out of or is based upon an omission to include in the Pricing Free Writing Prospectus information included in the Final Prospectus.

(b) The Underwriters agree to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each Person, if any, who controls the Company within the meaning of either the 1933 Act or the 1934 Act, to the same extent as the foregoing indemnity from the Company to the Underwriters, but only if any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with the Underwriters’ Information of the Underwriters except to the extent that such misstatement or omission arises from a misstatement or omission in the Company Provided Information. This indemnity will be in addition to any liability that the Underwriters may otherwise have. The Company and the Underwriters each acknowledge that (i) the term Underwriters’ Information shall mean the last paragraph on the cover page of the Prospectus Supplement and the first paragraph (including the table following such paragraph) and the first sentence of the second paragraph under the heading “Method of Distribution” in the Prospectus Supplement and (ii) Underwriters’ Information constitutes the only information furnished in writing by the Underwriters for inclusion in the documents referred to in the foregoing indemnity, and the Underwriters confirms that its Underwriters’ Information is correct.

(c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party otherwise than under this Section 9. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party or parties shall have reasonably concluded that there may be legal defenses available to it or them and/or other indemnified parties that are different from or additional to those available to the indemnifying party or there is a conflict or potential conflict between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), the indemnified party or parties shall have the right to elect separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel in addition to local counsel, approved by the Underwriters in the case of paragraph (a) of this Section 9), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall only be in respect of the counsel referred to in such clause (i) or (iii). Each indemnified party, as a condition of the indemnity agreements contained in Section 9(a) and (b), shall use its reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed) but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability (to the extent set forth in section 9(a) or (b) as applicable) by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or failure to act by or on behalf of an indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable or insufficient to hold harmless an indemnified party under this Section 9, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the aggregate losses, claims, damages and liabilities referred to in paragraph (a) or (b) above, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Certificates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Underwriters shall be equal to its aggregate discount and underwriting commissions with respect to the Offered Certificates purchased by it as set forth on Schedule I hereto, and the relative benefits of the Company shall be equal to the balance of the proceeds of the sale of the Offered Certificates. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. The amount paid or payable by an indemnified party as a result of the claims (or actions in respect thereof) referred to above shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such claim. Notwithstanding the provisions of this subsection (d), the Underwriters shall not be required to contribute any amount in excess of the amount by which the total amount of underwriting discounts and commissions received by the Underwriters with respect to the related Offered Certificates (which amounts are set forth in Schedule I hereto) exceeds the amount of damages which the Underwriters would have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, a Person, if any, that controls the Underwriters within the meaning of either the 1933 Act or the 1934 Act shall have the same rights to contribution as does the Underwriters and each director of the Underwriters and each officer of the Underwriters shall have the same rights to contribution as the Underwriters, and each Person, if any, that controls the Company within the meaning of either the 1933 Act or the 1934 Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d).

10. Termination. (a) This Agreement shall be subject to termination in the Underwriters’ absolute discretion, by notice given to the Company prior to delivery of and payment for the Offered Certificates, if, prior to such time, (i) trading of securities generally on the New York Stock Exchange or the American Stock Exchange or the over the counter market shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities, (iii) there shall have occurred any material outbreak or declaration of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in either Underwriter’s reasonable judgment, impracticable to market the Offered Certificates on the terms specified herein or (iv) if any other closing condition set forth in Section 6 shall not have been fulfilled when required to be fulfilled.

(b) If the sale of the Offered Certificates shall not be consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of the default of such Underwriter, the Company shall reimburse such Underwriter for the reasonable fees and expenses of such Underwriter’s counsel and for such other out-of-pocket expenses as shall have been incurred by such Underwriter in connection with this Agreement and the proposed purchase of the Offered Certificates, and upon demand the Company shall pay the full amount thereof to such Underwriter.

(c) This Agreement will survive delivery of and payment for the Offered Certificates. The provisions of Section 7 and this Section 8(c) shall survive the termination or cancellation of this Agreement and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of the Underwriters or any persons controlling it.

This free writing prospectus is being delivered to you solely to provide you with information about the offering and to solicit an offer to purchase the offered securities. Any such offer to purchase made by you will not be accepted and will not constitute a contractual commitment by you to purchase any of the securities until we have accepted your offer to purchase such securities. Any such commitment shall be subject to the conditions specified below.

This free writing prospectus is not required to contain all of the information that is required to be included in the base prospectus and the prospectus supplement. The information in this free writing prospectus is preliminary and is subject to completion or change. The information in this free writing prospectus, if conveyed prior to the time of your commitment to purchase the offered securities, supercedes any prior version of this free writing prospectus and any information contained in any prior similar free writing prospectus relating to these securities. If a preliminary prospectus is conveyed to you prior to your commitment to purchase, that document supersedes all other information provided to you concerning the offered securities.

This free writing prospectus is not an offer to sell or a solicitation of an offer to buy these securities in any state where such offer, solicitation or sale is not permitted.

The securities referred to in this free writing prospectus are being offered when, as and if issued. The issuer is not obligated to issue any such securities or any similar securities, and all or a portion of the securities may not be issued that have the characteristics described herein. The underwriters' obligation to deliver such securities is subject to the terms and conditions of the underwriting agreement with the issuer and the availability of the securities having the characteristics described herein. If, for any reason, the issuer does not deliver such securities, the underwriter will notify you, and neither the issuer nor any underwriter will have any obligation to you to deliver all or any portion of the securities which you have committed to purchase, and there will be no liability between us as a consequence of the non-delivery.

For asset-backed and mortgage-backed securities: Certain of the information contained herein may be based on numerous assumptions (including preliminary assumptions about the pool assets and structure), which may not be specifically identified as assumptions in the information. Any such information or assumptions are subject to change. The information in this free writing prospectus may reflect assumptions specifically requested by you. If so, prior to the time of your commitment to purchase, you should request updated information based on any assumptions specifically required by you.

Any legends, disclaimers or other notices that may appear below or on any electronic communication to which this free writing prospectus is attached which state that (1) these materials do not constitute an offer (or a solicitation of an offer), (2) no representation is made as to the accuracy or completeness of these materials and that these materials may not be updated or (3) these materials may be confidential are not applicable to this communication and should be disregarded.

Distribution of the Offered Certificates will be made from time to time in negotiated transactions or otherwise at varying prices to be determined at the time of sale. Proceeds to the Depositor from the sale of the Offered Certificates, before deducting expenses payable by the Depositor and underwriting fees, will be approximately $2,986,850,000. The Underwriters’ commission will be any positive difference between the price they pay to the Depositor for the Offered Certificates and the amount they receive from the sale of the Offered Certificates to the public. In connection with the purchase and sale of the Offered Certificates, the Underwriters may be deemed to have received compensation from the Depositor in the form of underwriting discounts.

The Depositor has been advised by the Underwriters that they propose initially to offer the Offered Certificates of each class to the public in Europe and the United States.

Until the distribution of the Offered Certificates is completed, rules of the SEC may limit the ability of the Underwriters and certain selling group members to bid for and purchase the Offered Certificates. As an exception to these rules, the Underwriters are permitted to engage in certain transactions that stabilize the price of the Offered Certificates. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Offered Certificates.

In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

None of the Depositor nor any Underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of the Offered Certificates. In addition, none of the Depositor nor any Underwriter makes any representation that the Underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

The Depositor has been advised by the Underwriters that they intend to make a market in the Offered Certificates but the Underwriters have no obligation to do so. There can be no assurance that a secondary market for the Offered Certificates will develop or, if it does develop, that it will continue.

The Depositor has agreed to indemnify the Underwriters against, or make contributions to the Underwriters with respect to, certain liabilities, including liabilities under the Securities Act of 1933, as amended.
