Ladies and Gentlemen:

Credit Suisse Commercial Mortgage Securities Corp., a Delaware corporation (the "Depositor"), proposes to sell to the several Underwriters listed in Schedule I (the "Underwriters"), $[_____] (approximate) principal amount of [CERTIFICATE CAPTION], [PUBLICLY OFFERED CERTIFICATES] (the "Offered Certificates") as set forth in Schedule I. The Offered Certificates, together with the [CERTIFICATE CAPTION], [PRIVATELY OFFERED CERTIFICATES] (the "Private Certificates"), are collectively referred to herein as the "Certificates." The initial purchasers of certain Private Certificates and the Underwriters are referred to herein collectively as the "Dealers." The Certificates will represent beneficial interests in a trust primarily consisting of a segregated pool of fixed-rate mortgage loans secured by commercial properties, as described in the Prospectus referred to below (the "Mortgage Loans"), and certain moneys received under each Mortgage Loan, after the cut-off date for such Mortgage Loan, which shall be: (i) the related due date of such Mortgage Loan in [DATE] or (ii) with respect to any Mortgage Loan that has its first due date in [DATE], the date that would have otherwise been the related due date in [DATE]. The Certificates will be issued pursuant to the provisions of a pooling and servicing agreement to be dated as of [DATE] (the "Pooling and Servicing Agreement"), between the Depositor, [MASTER SERVICER], as master servicer (the "Master Servicer"), [SPECIAL SERVICER], as Special Servicer (the "Special Servicer"), [CERTIFICATE ADMINISTRATOR AND TRUSTEE], as certificate administrator and as trustee (the "Certificate Administrator and Trustee"), [ASSET REPRESENTATIONS REVIEWER], as asset representations reviewer (the "Asset Representations Reviewer"), and [OPERATING ADVISOR], as operating advisor (the "Operating Advisor"). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement as in effect on the Closing Date (as defined below).

The Depositor hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Offered Certificates, as follows:

1. Registration Statement.

The Depositor has prepared and filed with the Securities and Exchange Commission (the "Commission") in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the "Securities Act"), a registration statement on Form SF‑3 (No. 333‑[_______]), as amended, relating to the Offered Certificates. The Depositor also has prepared and filed with the Commission a preliminary

prospectus dated [______] (the "[Initial] Preliminary Prospectus")[, as supplemented by a supplement thereto dated [_________] (the "Supplement", and together with the Initial Preliminary Prospectus, the "Preliminary Prospectus"), each] specifically relating to the Offered Certificates, in accordance with Rule 424(h) and Rule 430(D) under the Securities Act. [INCLUDE BRACKETED LANGUAGE IN PRECEDING SENTENCE ONLY IF A SUPPLEMENT TO PRELIMINARY WAS FILED PRIOR TO THE DATE OF THE UNDERWRITING AGREEMENT] The Depositor also has filed with, or proposes to file with, the Commission pursuant to Rule 424(b) under the Securities Act a prospectus specifically relating to the Offered Certificates (the "Prospectus"). The registration statement as amended at the time when it became effective, or, if a post-effective amendment is filed with respect thereto, as amended by such post-effective amendment at the time of its effectiveness, is referred to in this Agreement as the "Registration Statement." Any reference in this Agreement to the Registration Statement used in connection with the offering of the Offered Certificates, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any exhibits thereto and the documents incorporated by reference therein pursuant to Item 10(d) of Form SF‑3 under the Securities Act, as of the effective date of the Registration Statement or the date of the Preliminary Prospectus or the Prospectus, as the case may be, and any reference to "amend," "amendment" or "supplement" with respect to the Registration Statement, the Preliminary Prospectus and the Prospectus shall be deemed to refer to and include any documents filed after the date the Registration Statement became effective, or the date of the Preliminary Prospectus or the Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the "Exchange Act") that are deemed to be incorporated by reference therein.

At or prior to the time when sales to investors of the Offered Certificates were first made (the "Time of Sale"), the Depositor had prepared the following information (collectively, the "Time of Sale Information"): (i) a structural and collateral term sheet dated [DATE] (the cover page of which is attached hereto as Annex A) (the "Term Sheet") constituting a "free writing prospectus" (as defined pursuant to Rule 405 under the Securities Act) (a "Free Writing Prospectus"), (ii) the Preliminary Prospectus (the cover page of which is attached hereto as Annex B) [, and (iii) [IDENTIFY ANY OTHER PREVIOUSLY PREPARED TIME OF SALE INFORMATION]]. If, subsequent to the date of this Agreement, the Depositor and the Underwriters have determined that such information included an untrue statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and the applicable Underwriters have terminated their old purchase contracts and entered into new purchase contracts with investors in the Offered Certificates, then "Time of Sale Information" will refer to the information available to investors at the time of entry into the first such new purchase contract, including any information that corrects such material misstatements or omissions ("Corrective Information"), and "Time of Sale" will refer to the time and date on which such new purchase contracts were entered into.

When used in this Agreement, "Basic Documents" shall mean (i) the Pooling and Servicing Agreement, (ii) the Certificates, (iii) a mortgage loan purchase agreement, to be dated as of [DATE], between [SELLER] (in such capacity, "[SELLER]") and the Depositor (the "[SELLER MLPA]" and, together with the [OTHER MLPAS], the "Mortgage Loan Purchase

Agreements") and (iv) any other contract, agreement or instrument which is or is to be entered into by the Depositor on the Closing Date or otherwise in connection with any of the foregoing or this Agreement.

(u) Business Relationship with the Underwriters. The Depositor acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm's length contractual counterparty to the Depositor with respect to the offering of the Offered Certificates contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Depositor or any other person. Additionally, neither Credit Suisse Securities (USA) LLC nor any other Underwriter is advising the Depositor or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Depositor shall consult with its own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Depositor with respect thereto. Any review by the Underwriters of the Depositor, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Depositor. The Depositor acknowledges and agrees that: (i) the terms of this Agreement and the offering (including the price of the Certificates) were negotiated at arm's length between sophisticated parties represented by counsel; (ii) no fiduciary, advisory or agency relationship between the Depositor and any Underwriter has been or will be created as a result of any of the transactions contemplated by this Agreement, irrespective of whether any Underwriter has advised or is advising the Depositor on other matters; (iii) the Underwriters' obligations to the Depositor in respect of the offering, and the purchase and sale, of the Certificates are set forth in this Agreement in their entirety; (iv) the Depositor has obtained such legal, tax, accounting and other advice as it deems appropriate with respect to this Agreement and the transactions contemplated hereby and other activities undertaken in connection therewith, and it is not relying on the Underwriters with respect to any such matters; and (v) the Depositor will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or

(x) Mortgage Loan Criteria. At the Closing Date, each of the Mortgage Loans will meet the criteria for selection described in the Prospectus.

(y) Sale. Under generally accepted accounting principles and for federal income tax purposes, the Depositor will report the transfer of the Mortgage Loans to the Trustee in exchange for the Certificates and the sale of the Certificates to the Underwriters pursuant to this Agreement as a sale of the interest in the Mortgage Loans evidenced by the Certificates. The consideration received by the Depositor upon the sale of the Certificates to the Underwriters will constitute reasonably equivalent value and fair consideration for the Certificates.

The Depositor is not selling the Certificates to the Underwriters with any intent to hinder, delay or defraud any of the creditors of the Depositor

(b) Indemnification of the Depositor. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Depositor, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Depositor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission contained in (i) any Underwriters' Information specifically relating to such indemnifying Underwriter in the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (or any amendment or supplement thereto) or (ii) any Underwriter Free Writing Prospectus prepared by or on behalf of such indemnifying Underwriter (in the case of an omission or an alleged omission, when read in conjunction with the Time of Sale Information); provided that, with respect to the foregoing

clause (ii), no Underwriter shall be obligated to so indemnify and hold harmless (x) to the extent that the Depositor is entitled to indemnification or contribution therefor under the terms of the indemnity of any Seller, the Master Servicer, the Special Servicer, the Certificate Administrator and Trustee, the Asset Representations Reviewer or the Operating Advisor, as applicable, set forth in the applicable Indemnification Agreement, (y) with respect to information that is also contained in or otherwise made in reliance on or in conformity with the Time of Sale Information or the Prospectus or any Issuer Free Writing Prospectus or (z) to the extent such losses, claims, damages or liabilities are caused by a misstatement or omission resulting from an error or omission in the Issuer Information which was not corrected by Corrective Information subsequently supplied by the Depositor, any Seller, the Master Servicer, the Special Servicer, the Certificate Administrator and Trustee, the Asset Representations Reviewer or the Operating Advisor, as applicable, to the Underwriters at any time prior to the Time of Sale.

(c) Underwriter Indemnification. Each Underwriter (the "Indemnifying Underwriter") agrees, severally and not jointly, to indemnify and hold harmless each other Underwriter, its affiliates, directors and officers and each person, if any, who controls such other Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the "Non-Indemnifying Underwriter") from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted as such fees and expenses are incurred), joint or several, that arise out of or are based upon (i) any untrue statement or omission or alleged untrue statement or omission of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (in the case of clauses (A) and (B) when read in conjunction with the Time of Sale Information) contained in (A) any Underwriter Free Writing Prospectus prepared by the Indemnifying Underwriter, or any member of its selling group, in connection with the offer or sale of the Offered Certificates or in any revision or amendment thereof or supplement thereto, (B) the Registration Statement, (C) any Time of Sale Information, (D) the Prospectus and (E) any and all other summaries, reports, documents and written or electronic materials relating to the Certificates, prepared by the Indemnifying Underwriter or otherwise furnished or made available by the Indemnifying Underwriter for review by, prospective investors in the Offered Certificates, or (ii) the failure of such Indemnifying Underwriter, or any member of its selling group, to comply with any provision of Section 8, and agrees to reimburse such Non-Indemnifying Underwriter, as incurred for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, except to the extent (1) the Non-Indemnifying Underwriters are entitled to indemnification or contribution therefor under the terms of the indemnity from any Seller, the Master Servicer, the Special Servicer, the Certificate Administrator and Trustee, Asset Representations Reviewer, or the Operating Advisor, as applicable, set forth in the applicable Indemnification Agreement or by the Depositor under Section 7(a) hereof or (2) such losses, claims, damages or liabilities are caused by a misstatement or omission resulting from an error or omission in the Issuer Information which was not corrected by Corrective Information subsequently supplied by the Depositor, any Seller, the Master Servicer, the Special Servicer, the Certificate Administrator and Trustee, Asset Representations Reviewer, or the Operating Advisor, as applicable, to the Underwriters at any time prior to the Time of Sale; provided, further, that no Underwriter shall be liable to another Underwriter under this Section 7(c) for any losses, liabilities, claims or damages arising out of an untrue statement or alleged untrue

statement or omission or alleged omission in any such document prepared by such other Underwriter. This agreement will be in addition to any liability that any Underwriter may otherwise have.

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person that may seek indemnification pursuant to paragraph (a), (b) or (c) above, such person (the "Indemnified Person") shall promptly notify the person against whom such indemnification may be sought (the "Indemnifying Person") in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under Section 7(a), (b) or (c) except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under Section 7(a), (b) or (c). If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors, officers and any control persons of such Underwriter shall be designated in writing by such Underwriter and any such separate firm for the Depositor, its directors and officers who signed the Registration Statement and any control persons of the Depositor shall be designated in writing by the Depositor. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall,

without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in Sections 7(a), (b) or (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities and not otherwise covered by the indemnification provided for under such paragraph (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and Indemnified Person on the other from the offering of the Offered Certificates or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Depositor on the one hand and each Underwriter on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Depositor from the sale of the Offered Certificates and the total fees, discounts and commissions received by such Underwriter in connection therewith bear to the aggregate offering price of the Offered Certificates. The relative benefits received by a Non-Indemnifying Underwriter on the one hand and an Indemnifying Underwriter on the other shall be deemed to be in the same respective proportions as the total fees, discounts and commissions received by each such party in connection therewith bear to the aggregate offering price of the Offered Certificates. The relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information was supplied by the Indemnifying Person or the Indemnified Person and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Depositor and each Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall any Underwriter be required to contribute any amount in excess of the amount by which the total fees, discounts and commissions received by it with respect to the offering of the

Offered Certificates exceeds the amount of any damages that such Underwriter has 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Offering Communications; Free Writing Prospectuses; Preliminary Prospectus and Corrected Supplement.

(a) Unless preceded or accompanied by a prospectus satisfying the requirements of Section 10(a) of the Securities Act, no Underwriter shall convey or deliver any written communication to any person in connection with the initial offering of the Offered Certificates, unless such written communication (1) is made in reliance on Rule 134 under the Securities Act, (2) is made in reliance on Rule 172 under the Securities Act, (3) is the Time of Sale Information or the Prospectus or (4) constitutes a Free Writing Prospectus.

Notwithstanding the foregoing, any such Free Writing Prospectus that contains only ABS Informational and Computational Materials may be delivered by the Underwriters to the Depositor not later than the later of (a) two (2) business days prior to the due date for filing of the Prospectus pursuant to Rule 424(b) under the Securities Act or (b) the date of first use of such Free Writing Prospectus.

(f) Any Free Writing Prospectus required to be filed pursuant to Section 8(e) by the Depositor shall be filed with the Commission not later than the date of first use of the Free Writing Prospectus, except that:

(i) Any Free Writing Prospectus or portion thereof required to be filed that contains only the description of the final terms of the Certificates shall be filed by the Depositor with the Commission within two (2) days of the later of the date such final terms have been established for all classes of Certificates and the date of first use;

(ii) Any Free Writing Prospectus or portion thereof required to be filed that contains only ABS Informational and Computational Material shall be filed by the Depositor with the Commission not later than the later of the due date for filing the final Prospectus relating to the Offered Certificates pursuant to Rule 424(b) under the Securities Act or two (2) business days after the first use of such Free Writing Prospectus;

(iv) The Depositor shall not be required to file (A) Issuer Information contained in any Free Writing Prospectus of an Underwriter or any other offering participant other than the Depositor, if such information is included or incorporated by reference in a prospectus or Free Writing Prospectus previously filed with the Commission that relates to the offering of the Certificates, or (B) any Free Writing Prospectus or portion thereof that contains a description of the Certificates or the offering of the Certificates which does not reflect the final terms thereof.

(g) Each Underwriter shall provide to the Depositor any Free Writing Prospectus that is used or referred to by it and distributed by or on behalf of such Underwriter in a manner reasonably designed to lead to its broad, unrestricted dissemination not later than the date of the first use of such Free Writing Prospectus and the Depositor shall file such Free Writing Prospectus with the Commission.

(h) Notwithstanding the provisions of Section 8(g), each Underwriter shall provide to the Depositor, who shall then file with the Commission, any Free Writing Prospectus for which the Underwriter or any person acting on its behalf provided, authorized or approved information that is prepared and published or disseminated by a person unaffiliated with the Depositor or any other offering participant that is in the business of publishing, radio or television broadcasting or otherwise disseminating written communications and for which no payment was made or consideration given by or on behalf of the Depositor or any other offering participant, not later than four (4) business days after the Underwriter becomes aware of the publication, radio or television broadcast or other dissemination of the Free Writing Prospectus.

(i) Notwithstanding the provisions of Sections 8(e) and 8(g), neither the Depositor nor the Underwriters shall be required to file any Free Writing Prospectus that does not contain substantive changes from or additions to a Free Writing Prospectus previously filed with the Commission.

(j) The Depositor and the Underwriters each agree that any Free Writing Prospectuses prepared by it shall contain a legend substantially in the following form:

Alternatively, the depositor, [Credit Suisse Securities (USA) LLC] any [other] underwriter or any dealer participating in the offering will arrange

(k) In the event that the Depositor becomes aware that, as of the Time of Sale, the Preliminary Prospectus contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements contained therein, in the light of the circumstances under which they were made, not misleading, the Depositor shall (i) notify the Underwriters thereof within one business day after discovery, (ii) prepare and deliver to the Underwriters a supplement to the Preliminary Prospectus that corrects the material misstatement or omission in the Preliminary Prospectus and that meets the requirements of Rule 424(h)(2) under the Securities Act (such supplement, a "Corrected Supplement") and (iii) file such Corrected Supplement with the Commission in accordance with Rule 424(h) under the Securities Act. Upon receipt of such notice from the Depositor, the Underwriters shall:

(B) Upon receipt of a copy of such Corrected Supplement from the Depositor, deliver, at least 48 hours prior to sending a new confirmation of sale to an investor in the Offered Certificates in accordance with Rule 15c2-8(b) under the Exchange Act, such Corrected Supplement to such investor;

9. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Termination.

(a) Any Underwriter may terminate its obligations under this Agreement by notice to the Depositor at any time at or prior to the Closing Date if the sale of the Certificates provided for herein is not consummated because of any failure or refusal on the part of the Depositor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Depositor shall be unable to perform its obligations under this Agreement.

(b) The obligations of the Underwriters to purchase the Certificates on the Closing Date shall be terminable by the Underwriters (and, solely with respect to any Underwriter's obligation to purchase its respective allotment of the Certificates as specified in Schedule I, by such Underwriter) if at any time on or prior to the Closing Date: (i) any change, or any development or event involving a prospective change in the condition (financial or other), business, properties or results of operations of the Depositor or the Trust which, in the judgment of a majority in interest of the Underwriters, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Certificates; (ii) any downgrading in the rating of any of the Certificates by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any of the Certificates (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of a majority in interest of the Underwriters, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Certificates, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange or any over-the-counter market or any setting of minimum prices for trading on such exchange or market, or any suspension of trading of any Certificates on any relevant exchange or any over-the-counter market; (v) any general moratorium on commercial banking activities declared by any federal or New York State authorities; (vi) any major disruption of settlements of securities or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of a majority in interest of the Underwriters, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the offering or the sale of any payment for the Certificates.

(c) If any Underwriter terminates its obligations under this Agreement in accordance with Section 10(a), the Depositor shall reimburse such Underwriter for all reasonable out-of pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by such Underwriter in connection with the proposed purchase and sale of the Certificates.

11. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Offered Certificates that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Offered Certificates by other persons satisfactory to the Depositor on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Offered Certificates, then the Depositor shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Offered Certificates on such terms. If other persons become obligated or agree to purchase the Offered Certificates of a defaulting Underwriter,

either the non-defaulting Underwriters or the Depositor may postpone the Closing Date for up to five (5) full business days in order to effect any changes that in the opinion of counsel for the Depositor or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Depositor agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term "Underwriter" includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule I hereto that, pursuant to this Section 11, purchases Offered Certificates that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Offered Certificates of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Depositor as provided in paragraph (a) above, the aggregate principal amount of such Offered Certificates that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Offered Certificates, then the Depositor shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Offered Certificates that such Underwriter agreed to purchase hereunder plus such Underwriter's pro rata share (based on the principal amount of Offered Certificates that such Underwriter agreed to purchase hereunder) of the Offered Certificates of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Offered Certificates of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Depositor as provided in paragraph (a) above, the aggregate principal amount of such Offered Certificates that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Offered Certificates, or if the Depositor shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters or the Depositor, except that the Depositor will continue to be liable for the payment of expenses as set forth in Section 12 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Depositor or any non-defaulting Underwriter for damages caused by its default.

12. Payment of Expenses.

(b) If (i) this Agreement is terminated pursuant to Section 10; (ii) the Depositor for any reason fails to tender the Offered Certificates for delivery to the Underwriters; or (iii) the Underwriters decline to purchase the Offered Certificates for any reason permitted under this Agreement, the Depositor agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.
