Ladies and Gentlemen:

1. Introductory. Credit Suisse First Boston Mortgage Securities Corp., a Delaware corporation (the “Company”), proposes to form one or more real estate mortgage investment conduits (the “Trust”), which will issue certain securities entitled CSAIL 2015-C2 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2015-C2 and including the classes thereof specified on Schedule I hereto (the classes of such securities so specified on Schedule I hereto, the “Certificates”). Each Certificate will evidence a fractional undivided, percentage interest or beneficial interest in the Trust. The terms on which the Trust will issue the Certificates will be specified in the Prospectus (as defined herein). The property of the Trust will consist of a pool of 118 fixed rate mortgage loans secured by commercial, multifamily and manufactured housing community properties (collectively, the “Mortgage Loans”) that will be purchased by the Company from Column Financial, Inc. (the “Column Mortgage Loan Seller”), MC-Five Mile Commercial Mortgage Finance LLC (the “MC-Five Mile Mortgage Loan Seller”), The Bancorp Bank (the “Bancorp Mortgage Loan Seller”), BSPCC Lender L.L.C. (the “BSPCC Mortgage Loan Seller”), Jefferies LoanCore LLC (the “JLC Mortgage Loan Seller”) and UBS Real Estate Securities Inc. (the “UBSRES Mortgage Loan Seller” and, together with the Column Mortgage Loan Seller, the MC-Five Mile Mortgage Loan Seller, the Bancorp Mortgage Loan Seller, the BSPCC Mortgage Loan Seller and the JLC Mortgage Loan Seller, the “Mortgage Loan Sellers”), pursuant to those certain Mortgage Loan Purchase Agreements, each dated as of May 1, 2015 (collectively, the “Mortgage Loan Purchase Agreements”), and will be serviced by Wells Fargo Bank, National Association, as master servicer (in such capacity, the “Master Servicer”), and, if and when necessary, Rialto Capital Advisors, LLC, as special servicer (the “Special Servicer”), pursuant to that certain Pooling and Servicing Agreement (the “Pooling and Servicing Agreement”), dated as of May 1, 2015, by and among the Company, as depositor, the Master Servicer, the Special Servicer, Park Bridge Lender Services LLC, as operating advisor (the “Operating Advisor”), Wells Fargo Bank, National Association, as certificate administrator (in such capacity, the “Certificate Administrator”) and

Wilmington Trust, National Association, as trustee (the “Trustee”), and certain related property to be conveyed to the Trust by the Company (the “Trust Fund”). The Mortgage Loans will be transferred to the Trust, and the Certificates will be issued pursuant to the Pooling and Servicing Agreement.

The offering of the Certificates made pursuant to the Registration Statement (as defined below) will be made through you, as underwriters (the “Underwriters” and, individually, an “Underwriter”). This Agreement provides for the sale of such Certificates to, and the purchase and offering thereof by, you, as underwriters. Schedule I shall specify the principal balance or notional amount of each class of the Certificates to be issued and any terms thereof not otherwise specified in the Pooling and Servicing Agreement, the classes of Certificates subject to this Agreement, the price at which such Certificates are to be purchased by the Underwriters from the Company and the aggregate amount of each class of Certificates to be purchased by each Underwriter. The offering of the Certificates will be governed by this Agreement. Capitalized terms used but not defined herein shall have the meanings given to them in the Pooling and Servicing Agreement, as in effect on the Closing Date (as defined in Section (5)(d) of this Agreement).

At or prior to the time when sales to purchasers of the Certificates were first made, which was approximately (A) 3:15 p.m. (Eastern Time) on May 6, 2015 with respect to the Certificates (other than the Class X-A and Class X-B Certificates), and (B) 2:15 p.m. (Eastern Time) on May 8, 2015 with respect to the Class X-A and Class X-B Certificates (the “Time of Sale”), the Company had prepared or made available the following information (collectively, the “Rule 159 Information”): (i) the Free Writing Prospectus, dated April 30, 2015 (the cover page of which is attached hereto as Annex A) (the “Preliminary Free Writing Prospectus”), (ii) the Structural and Collateral Term Sheet, dated April 30, 2015 (the cover page of which is attached hereto as Annex B) (the “Term Sheet”), (iii) the Company’s base prospectus, dated March 3, 2015 (the “Base Prospectus”), and (iv) certain other “free-writing prospectuses” (as defined pursuant to Rule 405 under the Securities Act) (the first page of which is attached hereto as Annex C) (each of items (i), (ii) and (iv), a “Free Writing Prospectus”). If, subsequent to the date of this Agreement, the Company and the Underwriters (x) determine 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 (y) terminate their old purchase contracts and enter into new purchase contracts with investors in the Certificates, then “Rule 159 Information” will refer to the information, including any information that corrects such material misstatements or omissions, conveyed to purchasers at the time of entry into the first such new purchase contract, and “Time of Sale” will refer to the time and date on which such new purchase contracts were entered into.

7. Indemnification. (a) The Company shall indemnify and hold harmless each Underwriter, each of its officers and each of its directors and each person, if any, that controls any Underwriter within the meaning of the Securities Act or the Exchange Act against any expenses, losses, claims, damages or liabilities, joint or several, to which such Underwriter or such officer, director or controlling person may become subject under the Securities Act, the Exchange Act or otherwise, and shall reimburse any legal or other expenses reasonably incurred by such Underwriter or any such director, officer, or controlling person in connection with investigating or defending any such expense, loss, claim, damage, liability or action, in each case insofar as such expenses, losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement (which, for the avoidance of doubt, includes, without limitation, the Prospectus) or any amendment or supplement thereto or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of any material fact contained in (x) any Issuer Free Writing Prospectus or (y) any Issuer Information (as defined in Section 8(b)) contained in (1) any Underwriter Free Writing Prospectus (as defined in Section 8(b) hereof) prepared by or on behalf of such Underwriter, or (2) any Free Writing Prospectus that is required to be filed pursuant to Section 8(e)(iii) or Section 8(h) hereof (clauses (x) and (y) collectively, the “Issuer Disclosure Materials”), or the omission or alleged omission to state a material fact required to be stated therein or necessary in order to make the statements therein (when read in conjunction with the other Rule 159 Information), in the light of the circumstances under which they were made, not misleading, which untrue statement or omission referred to in this clause (ii) was not corrected by information subsequently supplied by the Company or any Mortgage Loan Seller to such Underwriter within a reasonable period of time prior to the Time of Sale or (iii) any breach of the representation and warranty in Section 2(v).

Notwithstanding the foregoing, (i) the Company shall not be liable in any such case to the extent that any such expense, loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement in, or omission or alleged omission from, any such documents in reliance upon and in conformity with (A) any Underwriter Information, (B) any Mortgage Loan Seller Information, or (C) any Transaction Party Information, but in the case of clauses (B) and (C), only to the extent that that the Underwriters and Company are actually indemnified by the applicable party and (ii) such indemnity with respect to an untrue statement or omission of a material fact made in any Issuer Disclosure Materials that are part of the initial Rule 159 Information shall not inure to the benefit of any Underwriter if information that corrected any untrue statement or omission of a material fact was furnished to the Underwriters at a reasonable time prior to the Time of Sale.

(b) The Company acknowledges that the following statements constitute the only “Underwriter Information” furnished in writing by or on behalf of the Underwriters for inclusion in the Prospectus: the first sentence of the second to last paragraph on the

-16-

cover of the Prospectus Supplement; and the fourth paragraph, the fifth paragraph (but only the second sentence thereof) and the sixth paragraph (but only the first sentence thereof) under the heading “Plan of Distribution (Underwriter Conflicts of Interest)” in the Prospectus Supplement. This indemnity agreement shall be in addition to any liability which the Company may otherwise have.

(c) Each Underwriter shall severally, and not jointly, indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act against any expenses, losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Securities Act, the Exchange Act or otherwise, and shall reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such expense, loss, claim, damage, liability or action, in each case insofar as such expenses, losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statements of a material fact, or omissions or alleged omissions to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in the Underwriter Information with respect to such Underwriter and (ii) untrue statements or alleged untrue statements of a material fact in any Underwriter Free Writing Prospectus (as defined in Section 8(b)) prepared by or on behalf of such Underwriter or omission or alleged omission to state in such Underwriter Free Writing Prospectus a material fact required to be stated therein or necessary in order to make the statements therein (when read in conjunction with the Rule 159 Information), in the light of the circumstances under which they were made, not misleading; except that, in the case of clause (ii), no Underwriter shall be obligated so to indemnify and hold harmless the Company (x) for any losses, claims, damages or liabilities arising out of or based upon an untrue statement, alleged untrue statement, omission or alleged omission (including those of a quantitative nature) with respect to any Mortgage Loan Seller Information provided by a Mortgage Loan Seller or in any Transaction Party Information provided by a Transaction Party, as the case may be; (y) for any losses, claims, damages or liabilities arising out of or based upon an untrue statement, alleged untrue statement, omission or alleged omission (including those of a quantitative nature) with respect to any Issuer Information (as defined in Section 8(b) hereof); or (z) to the extent that the Company is entitled to indemnification or contribution therefor from any Mortgage Loan Seller or any Transaction Party pursuant to any Indemnification Agreement. Notwithstanding the foregoing, the indemnity provided in clause (ii) in the immediately preceding sentence will apply only if such misstatement or omission was not also a misstatement or omission in the Rule 159 Information. This indemnity agreement shall be in addition to any liability that such Underwriter may otherwise have.

(d) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party of the commencement thereof; but the omission to so notify the

-17-

indemnifying party shall not relieve it from any liability which it may have to any indemnified party under Section 7 (a) and (c), except to the extent that such omission to notify materially prejudices the indemnifying party, or relieve it from any liability that it may have other than under this Agreement. Upon request of the indemnified party, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party) to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding as incurred. In case any such action is brought against any indemnified party, after such indemnifying party has been notified of the commencement thereof, such indemnifying party shall be entitled to participate therein (at its own expense), and, to the extent that it may wish, shall be entitled to assume the defense thereof (jointly with any other indemnifying party similarly notified) with counsel reasonably satisfactory to such indemnified party (which shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election to so assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to designate within a reasonable period of time counsel reasonably satisfactory to the indemnified party (in which case the fees and expenses shall be paid by the indemnifying party as incurred by the indemnified party). In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed). However, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party shall indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing two sentences, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel for which the indemnifying party is obligated under this Section 8(d), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such settlement does not include

-18-

a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of the indemnifying party. If an indemnifying party assumes the defense of any proceeding, it shall be entitled to settle such proceeding with the consent of the indemnified party or, if such settlement (i) provides for an unconditional release of the indemnified party in connection with all matters relating to the proceeding that have been asserted against the indemnified party in such proceeding by the other parties to such settlement and (ii) does not require or contain a statement as to, or an admission of fault, culpability or failure to act by or on behalf of the indemnified party, without the consent of the indemnified party.

(e) If recovery is not available under the foregoing indemnification provisions of this Section 7 or is insufficient in respect of any liabilities referred to therein (on grounds of public policy or otherwise), the parties entitled to indemnification by the terms thereof shall be entitled to contribution to liabilities and expenses, except to the extent that contribution is not permitted under Section 11(f) of the Securities Act. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative benefits received by the Company on the one hand and each Underwriter on the other from the offering of the Certificates subject to this Agreement (taking into account the portion of the proceeds of the offering realized by each). In the event contribution according to the foregoing sentence is not permitted by law, in determining the amount of contribution to which the respective parties are entitled, there shall be considered not only the relative benefits received by the Company on the one hand and such Underwriter on the other from the offering of the Certificates but also the parties’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission and any other equitable considerations appropriate under the circumstances. The Company and the Underwriters agree that it would not be equitable if the amount of such contribution 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 which does not take account of the equitable considerations referred to above in this Section 8(e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions and other fees received by such Underwriter in connection with the offering of the Certificates exceeds the amount of damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The obligations of the Underwriters in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) The amount paid or payable by an indemnified party as a result of the losses, claims, damages or other liabilities referred to in this Section 7 shall be deemed to include any legal fees and disbursements or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such claim. In the event that any expenses so paid by the indemnifying party are subsequently determined to not be required to be borne by the indemnifying party hereunder, the party which received such payment shall promptly refund the amount so paid to the party which made such payment. No person guilty of fraudulent misrepresentation (within the meaning of

-19-

Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution agreements contained in this Section 7 shall remain operative and in full force and effect regardless of (i) any termination or cancellation of this Agreement, (ii) any investigation made by the Company, any Underwriter, any of their respective directors or officers, or any person controlling the Company or such Underwriter, and (iii) acceptance of and payment for any of the Certificates.

(h) The obligations of the Company under this Section 7 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of any Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act or Exchange Act.

(i) Each Underwriter will indemnify and hold harmless the other Underwriters and each person, if any, who controls such Underwriters within the meaning of either the Securities Act or the Exchange Act (the “Non-Indemnifying Underwriters”) from and against any and all expenses, losses, claims, damages or liabilities, joint or several, to which the Non-Indemnifying Underwriters become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, common law or otherwise, insofar as such expenses, losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact or the omission or alleged omission (when read in conjunction with the Rule 159 Information) to state a material fact required to be stated therein or necessary in order to make the statements in the light of the circumstances under which they were made, not misleading at the Time of Sale, contained in any Underwriter Free Writing Prospectus prepared by or on behalf of such indemnifying Underwriter, or (ii) any untrue statement or alleged untrue statement of a material fact regarding the indemnifying Underwriter contained in the Underwriter Information or the omission or alleged omission to state therein a material fact required to be stated therein regarding the indemnifying Underwriter or necessary in order to make the statements therein regarding the indemnifying Underwriter, in the light of the circumstances under which they were made, not misleading, or (iii) the failure of such indemnifying Underwriter, or any member of its selling group to comply with any provision of Section 8 hereof (any such expenses, losses, claims, damages or liabilities arising out of or based on the events described in clauses (i) - (iii), “Covered Liabilities”). In addition, each Underwriter agrees to reimburse such Non-Indemnifying Underwriters for any legal or other expenses reasonably incurred by them in connection with investigating or defending against any such Covered Liabilities or any action in respect

-20-

thereof, except to the extent that the Non-Indemnifying Underwriters are entitled to indemnification or contribution therefor from any Mortgage Loan Seller or any Transaction Party pursuant to any Indemnification Agreement. If recovery is not available under the foregoing indemnification provisions of this Section 7(i) or is insufficient in respect of any Covered Liabilities (on grounds of public policy or otherwise), each Underwriter agrees to pay, upon request, as contribution, its pro rata share of any Covered Liabilities, and such Underwriter’s pro rata share of any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending such Covered Liabilities or any action in respect thereof, except to the extent that the Non-Indemnifying Underwriters are entitled to indemnification or contribution therefor from any Mortgage Loan Seller or any Transaction Party pursuant to any Indemnification Agreement; provided that no request shall be made on behalf of any Underwriter if such Underwriter is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) from any Underwriter who was not guilty of such fraudulent misrepresentation; provided, further, that no Underwriter shall be entitled to contribution under this Section 7(i) from any other Underwriters for any Covered Liabilities or expenses for which the Underwriter seeking contribution (or its affiliate) would otherwise be required (or, if such indemnification obligations are held to be unenforceable on the grounds of public policy or otherwise, would otherwise have been required) to indemnify such other Underwriters. The obligations of the Underwriters in this subsection (i) to contribute are several in proportion to their respective underwriting obligations and not joint. This agreement will be in addition to any liability that any Underwriter may otherwise have.

8. Offering Communications; Free Writing Prospectuses. (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 Certificates, unless such written communication (i) is made in reliance on Rule 134 under the Securities Act, (ii) is made in reliance on Rule 172 under the Securities Act, (iii) constitutes a prospectus satisfying the requirements of Rule 430B under the Securities Act or (iv) constitutes Rule 159 Information or a Free Writing Prospectus. Without limitation thereby, without the prior written consent of the Company (which consent may be withheld for any reason), no Underwriter shall prepare, convey or deliver in connection with the initial offering of the Certificates any Free Writing Prospectus or “ABS informational and computational material,” as defined in Item 1101(a) of Regulation AB under the Securities Act (“ABS Informational and Computational Material”), in reliance upon Rules 167 and 426 under the Securities Act other than materials provided to it by Credit Suisse Securities (USA) LLC or the Company.

(b) Each Underwriter shall deliver to the Company, no later than two (2) business days prior to the date of first use thereof or such later date as may be agreed to by the Company, (i) any Free Writing Prospectus that was prepared by or on behalf of such Underwriter (an “Underwriter Free Writing Prospectus”) and that contains any “issuer information,” as defined in Rule 433(h) under the Securities Act and footnote 271 of the Commission’s Securities Offering Reform Release No. 33-8591 (“Issuer Information”) (which the parties hereto agree includes, without limitation, Mortgage Loan Seller Information), and (ii) any Free Writing Prospectus or portion thereof

-21-

prepared by or on behalf of such Underwriter that contains only a description of the final terms of the Certificates. Notwithstanding the foregoing, any Free Writing Prospectus that contains only ABS Informational and Computational Materials may be delivered by an Underwriter to the Company 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 such later date as may be agreed to by the Company or (B) the date of first use of such Free Writing Prospectus. It is acknowledged and agreed that the Rule 159 Information does not include any Underwriter Free Writing Prospectus.

(c) Each Underwriter represents and warrants to the Company that the Free Writing Prospectuses to be furnished to the Company by such Underwriter pursuant to Section 8(b) hereof will constitute all Free Writing Prospectuses of the type described therein that were furnished to prospective investors by such Underwriter in connection with its offer and sale of the Certificates.

(d) Each Underwriter represents and warrants to the Company that each Free Writing Prospectus required to be provided by it to the Company pursuant to Section 8(b) hereof did not, as of the Time of Sale, include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements contained therein (when read in conjunction with the Rule 159 Information), in the light of the circumstances under which they were made, not misleading; provided however, that no Underwriter makes any representation to the extent such misstatements or omissions were the result of any inaccurate Issuer Information, Mortgage Loan Seller Information or Transaction Party Information, which information was not corrected by information subsequently supplied by the Company or any Mortgage Loan Seller to such Underwriter within a reasonable period of time prior to the Time of Sale.

(e) The Company agrees to file with the Commission the following:

(i) Any Issuer Free Writing Prospectus;

(ii) Any Free Writing Prospectus or portion thereof delivered by an Underwriter to the Company pursuant to Section 8(b) hereof; and

(iii) Any Free Writing Prospectus for which the Company 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 Company or any other offering participant that is in the business of publishing, radio or television broadcasting or otherwise disseminating communications.

(f) Any Free Writing Prospectus required to be filed pursuant to Section 8(e)(iii) hereof by the Company 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 may be filed by the Company 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;

-22-

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

(iii) any Free Writing Prospectus required to be filed pursuant to Section 8(e)(iii) hereof may, if no payment has been made or consideration has been given by or on behalf of the Company for such Free Writing Prospectus or its dissemination, be filed by the Company with the Commission not later than four (4) business days after the Company becomes aware of the publication, radio or television broadcast or other dissemination of such Free Writing Prospectus.

(g) Each Underwriter (with the reasonable cooperation of the Company) shall file with the Commission, or provide to the Company at least two (2) business days prior to the time such filing is required (and the Company shall file with the Commission), any Free Writing Prospectus (other than a Free Writing Prospectus required to be delivered to the Company pursuant to Section 8(b)) that is neither an Issuer Free Writing Prospectus nor contains Issuer Information and that is used or referred to by it and distributed by or on behalf of such Underwriter which is neither an Issuer Free Writing Prospectus nor contains Issuer Information 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.

(h) Notwithstanding the provisions of Section 8(g) hereof, each Underwriter shall file with the Commission any Free Writing Prospectus for which such 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 Company 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 Company 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) (other than Section 8(e)(iii)), 8(g) and 8(h) hereof: (A) neither the Company nor any Underwriter shall be required to file (1) any Free Writing Prospectus that does not contain substantive changes from or additions to a Free Writing Prospectus previously filed with the Commission, (2) 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 or (3) Issuer Information contained in any Underwriter Free Writing Prospectus or Free Writing Prospectus of any other offering participant other than the Company, 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; and (B) no Underwriter shall be required to file any Free Writing

-23-

Prospectus to the extent that the information contained therein is included in a prospectus or Free Writing Prospectus previously filed that relates to the offering of the Certificates.

(j) The Company and the Underwriters each agree that any Free Writing Prospectuses prepared by it shall contain the following legend, or substantially equivalent legend that complies with Rule 433 of the Securities Act:

“The depositor has filed a registration statement (including the prospectus) with the SEC (SEC File No. 333-199921) for the offering to which this communication relates. Before you invest, you should read the prospectus in the registration statement and other documents the depositor has filed with the SEC for more complete information about the depositor, the issuing entity and this offering. You may get these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the depositor or Credit Suisse Securities (USA) LLC, any other underwriter, or any dealer participating in this offering will arrange to send to you the prospectus if you request it by calling toll-free ###-###-####.”

(k) The Company and the Underwriters each agree to retain all Free Writing Prospectuses that they have used and that are not required to be filed pursuant to this Section 8 for a period of three (3) years following the initial bona fide offering of the Certificates.

(l) (i) In the event that the Company becomes aware that, as of the Time of Sale, any Issuer Free Writing Prospectus contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained therein (when read in conjunction with the Rule 159 Information), in the light of the circumstances under which they were made, not misleading (a “Defective Issuer Free Writing Prospectus”), the Company shall notify the Underwriters of such untrue statement or omission within one business day after discovery and the Company shall, if requested by the Underwriters, prepare and deliver to the Underwriters a Free Writing Prospectus that corrects the material misstatement or omission in the Defective Issuer Free Writing Prospectus (such corrected Issuer Free Writing Prospectus, a “Corrected Issuer Free Writing Prospectus”).

(ii) In the event that any Underwriter becomes aware that, as of the Time of Sale, any Underwriter Free Writing Prospectus delivered to an investor in any Certificates contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements contained therein (when read in conjunction with the Rule 159 Information), in the light of the circumstances under which they were made, not misleading (together with a Defective Issuer Free Writing Prospectus, a “Defective Free Writing Prospectus”), such Underwriter shall notify the Company of such untrue statement or omission within one business day after discovery.

(iii) The Underwriters shall, if requested by the Company:

(1) if the Defective Free Writing Prospectus was an Underwriter Free Writing Prospectus, prepare a Free Writing Prospectus

-24-

that corrects the material misstatement in or omission from the Defective Free Writing Prospectus (together with a Corrected Issuer Free Writing Prospectus, a “Corrected Free Writing Prospectus”);

(2) either (i) deliver the Corrected Free Writing Prospectus to each investor which received the Defective Free Writing Prospectus prior to entering into a contract of sale with such investor, clearly identifying or highlighting the Corrective Information, or (ii) deliver the Corrected Free Writing Prospectus to each investor that received the Defective Free Writing Prospectus and has entered into a contract of sale, clearly identifying or highlighting the Corrective Information;

(3) notify such investor in a prominent fashion that the prior contract of sale with the investor has been terminated, and of the investor’s rights as a result of termination of such agreement;

(4) provide such investor with an opportunity to affirmatively agree to purchase the Certificates on the terms described in the Corrected Free Writing Prospectus; and

(5) comply with any other requirements for reformation of the original contract of sale with such investor, as described in Section IV.A.2.c of Commission’s Securities Offering Reform Release No. 33-8591.

(iv) In the event that the Defective Free Writing Prospectus was an Issuer Free Writing Prospectus or in the event that any Underwriter Free Writing Prospectus contains any inaccurate Issuer Information supplied by the Company or any Mortgage Loan Seller to the related Underwriter, and the Underwriters shall in good faith incur any costs to an investor in connection with the reformation of the contract of sale with the investor, the Company agrees to reimburse the Underwriters for such costs; provided that, before incurring such costs, the Underwriters first permits the Company access to the applicable investor and an opportunity to attempt to mitigate such costs through direct negotiation with such investor.

(v) Each Underwriter covenants with the Company that after the Prospectus is available such Underwriter shall not distribute any written information concerning the Certificates to a prospective investor unless such information is preceded or accompanied by the Prospectus.

(m) Each Underwriter covenants with the Company that it will make available to the Company, upon reasonable request, such personnel as are familiar with the Underwriter’s compliance procedures for the purpose of answering questions concerning the Underwriter’s practices and procedures for the preparation and dissemination of written materials concerning the Certificates to prospective investors prior to the delivery of the Prospectus to such investors.

9. Default of Underwriters. If any Underwriter defaults in its obligations to purchase Certificates hereunder and the aggregate principal amount of Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Certificates to be purchased hereunder, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Certificates by other persons, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated to purchase the Certificates that such defaulting Underwriter agreed but failed to purchase hereunder. If any Underwriter so defaults and the aggregate principal amount of Certificates with respect to which such default occurs exceeds 10% of the total principal amount of Certificates to be purchased hereunder and arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of such Certificates by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

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

(b) The obligations of the Underwriters to purchase the Certificates on the Specified Delivery 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 Specified Delivery 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 Company or the Trust Fund 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

-26-

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 Company 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. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements by the Company and of the several Underwriters set forth in or made pursuant to this Agreement shall remain in full force and effect, regardless of any investigation or statement as to the results thereof made by or on behalf of such Underwriters, the Company or any of their respective officers or directors or any controlling person, and shall survive delivery of and payment of the related Certificates.

If this Agreement is terminated pursuant to Section 10 above or if for any reason the purchase by the Underwriters of the Certificates is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5(g) above, and the obligations of the Company and such Underwriters pursuant to Section 7 above shall remain in effect.

12. Obligations of Column Financial, Inc.

**************************************************************************

Investors are urged to read the final prospectus supplement relating to these securities because it contains important information regarding the offering that is not included herein. The issuer, any underwriter or any dealer participating in the offering will arrange to send you the final prospectus supplement if you request it by calling toll-free 1-800-211-1037.

The asset-backed securities referred to in these materials, and the asset pool backing them, are subject to modification or revision (including the possibility that one or more classes of securities may be split, combined or eliminated at any time prior to issuance or availability of a final prospectus) and are offered on a "when, as and if issued" basis. You understand that, when you are considering the purchase of these securities, a contract of sale will come into being no sooner than the date on which the relevant class has been priced and we have confirmed the allocation of securities to be made to you; any "indications of interest" expressed by you, and any "soft circles" generated by us, will not create binding contractual obligations for you or us.

Because the asset-backed securities are being offered on a "when, as and if issued" basis, any such contract will terminate, by its terms, without any further obligation or liability between us, if the securities themselves, or the particular class to which the contract relates, are not issued. Because the asset-backed securities are subject to modification or revision, any such contract also is conditioned upon the understanding that no material change will occur with respect to the relevant class of securities prior to the closing date. If a material change does occur with respect to such class, our contract will terminate, by its terms, without any further obligation or liability between us (the "Automatic Termination"). If an Automatic Termination occurs, we will provide you with revised offering materials reflecting the material change and give you an opportunity to purchase such class. To indicate your interest in purchasing the class, you must communicate to us your desire to do so within such timeframe as may be designated in connection with your receipt of the revised offering materials.

The information contained in these materials may be based on assumptions regarding market conditions and other matters as reflected herein. Credit Suisse Securities (USA) LLC and the other underwriters make no representation regarding the reasonableness of such assumptions or the likelihood that any such assumptions will coincide with actual market conditions or events, and these materials should not be relied upon for such purposes. The underwriters and their respective affiliates, officers, directors, partners and employees, including persons involved in the preparation or issuance of these materials, may, from time to time, have long or short positions in, and buy and sell, the securities mentioned herein or derivatives thereof (including options). Credit Suisse Securities (USA) LLC and the other underwriters may have an investment or commercial banking relationship with the issuer.

Information in these materials is current as of the date appearing on the material only. This free writing prospectus is not required to contain all 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 subject to change. Information in these materials regarding any securities discussed herein supersedes all prior information regarding such securities. These materials are not to be construed as an offer to sell or the solicitation of any offer to buy any security in any jurisdiction where such an offer or solicitation would be illegal. You should consult your own counsel, accountant and other advisors as to the legal, tax, business, financial and related aspects of a purchase of these securities.

The issuer has filed a registration statement (including a prospectus) with the SEC (registration statement file no. 333-199921) for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering.

Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling toll-free 1-800-211-1037.
