Each class of the Offered Certificates will have the aggregate principal balance or notional amount set forth in the Prospectus, subject to an upward or downward variance in principal or notional amount, not to exceed the percentage set forth in the Prospectus.

The Trust Interests are to be issued under a pooling and servicing agreement, dated as of May 1, 2017 (the “PSA”), between the Depositor, Xxxxx Fargo Bank, National Association, as master servicer (in such capacity, the “Master Servicer”), Midland Loan Services, a Division of PNC Bank, National Association, as special servicer (the “Special Servicer”), Wilmington Trust, National Association, as trustee (the “Trustee”), Xxxxx Fargo Bank, National Association, as certificate administrator (in such capacity, the “Certificate Administrator”), and Park Bridge Lender Services LLC, as asset representations reviewer (in such capacity, the “Asset Representations Reviewer”) and operating advisor (in such capacity, the “Operating Advisor”; and the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer and the Operating Advisor, collectively, the “PSA Transaction Parties,” and each, a “PSA Transaction Party”).

1. Representations, Warranties and Select Covenants.

(a) The Depositor represents and warrants to, and covenants with, the Underwriters as follows:

(i) The Depositor has filed with the Commission a registration statement (No. 333-206582) on Form SF-3 for the registration of the Offered Certificates under the Securities Act of 1933 (the “1933 Act”), which registration statement was, is and will be effective as of the date hereof, as of each Time of Sale (as defined below), as of any Subsequent Time of Sale (as defined below), as of any other time that an Underwriter enters into a contract of sale for an Offered Certificate and as of the Closing Date. The Depositor also has prepared and filed with the Commission a preliminary prospectus dated April 26, 2017 (the “Preliminary Prospectus”), specifically relating to the Offered Certificates, in accordance with Rule 424(h) and Rule 430D under the 1933 Act. If the Depositor had elected to defer payment of all or any portion of the registration fee to the Commission required by Section 6(b)(1) of the 1933 Act in connection with the offering of the Offered Certificates, then as of the date of the filing of the Preliminary Prospectus (i) the Depositor had satisfied the conditions specified in Rule 456(c)(1) under the 1933 Act with respect to the offering of the Offered Certificates, (ii) the registration statement referred to above was considered filed as to the Offered Certificates in accordance with Rule 456(c)(2) under the 1933 Act and (iii) the Offered Certificates were considered registered in accordance with Section 456(c)(3) under the 1933 Act. Following the initial Time of Sale for any class of Offered Certificates, the Depositor also filed with, or proposes to file with, the Commission pursuant to Rule 424(b) under the 1933 Act a prospectus specifically relating to the Offered Certificates (the “Prospectus”). In accordance with Rule 172(c) of the 1933 Act, if it has not done so already, the Depositor shall make a good faith and reasonable effort to file the Prospectus, in the form that satisfies Section 10(a) of the 1933 Act, within the time required under Rule 424 under the 1933 Act and, if the Depositor fails to timely file the Prospectus, the Depositor shall file the Prospectus as soon as practicable thereafter. The Depositor also has filed with, or proposes to file with, the Commission pursuant to Item 1111(h) and Item 1125 of Regulation AB under the 1933 Act a Form ABS-EE (together with the exhibits thereto) with respect to each of the Preliminary Prospectus and the Prospectus, specifically relating to the Offered Certificates (the “Form ABS-EE”). The registration statement referred to above 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(a) or 10(d) of Form SF-3 under the 1933 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, after the date of the Preliminary Prospectus or after the date of filing of the Prospectus, as the case may

be, under the 1934 Act, and the rules and regulations of the Commission thereunder that are deemed to be incorporated by reference therein.

The Time of Sale Information was delivered to investors in the Offered Certificates prior to the Time of Sale. If, subsequent to the date of this Agreement, the Depositor or the Underwriters determine that, as to investors in one or more Classes of the Offered Certificates, the Time of Sale Information as of the Time of Sale 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 Underwriters terminate their old purchase contracts and enter into new purchase contracts with investors in such Classes of the Offered Certificates, then “Time of Sale Information” shall also refer to the additional information conveyed to investors at the time of entry into such new purchase contract (each, a “Subsequent Time of Sale”), 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.

LLC, …”) on the cover page of each of the Preliminary Prospectus and the Prospectus. Any Issuer Information (as defined below) provided by the Depositor to any Underwriter, as of the date that such Issuer Information was so provided for inclusion in an Underwriter Free Writing Prospectus (as defined below), did not, as of the date that such Issuer Information was so provided, and does not,

as of the date of this Agreement, contain an untrue statement of a material fact or omit 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; provided, that the Depositor shall not be in breach of this representation if the Depositor provided Issuer Information to the Underwriters, correcting such untrue statement or omission of a material fact contained in previously delivered Issuer Information, so long as the Depositor delivered the corrected information to the Underwriters a reasonable period time prior to the Time of Sale.

(iv) The conditions to the use by the Depositor of a registration statement on Form SF-3 under the 1933 Act, as set forth in the General Instructions to Form SF-3, in connection with the offering and sale of the Offered Certificates as contemplated by the Prospectus, have been satisfied or will be satisfied as of the date on which the Prospectus is required to be filed with the Commission pursuant to Rule 424(b) under the 1933 Act with respect to the Registration Statement and the Prospectus. If and to the extent applicable with respect to the Registration Statement, the requirements of General Instruction I.A. of Form SF-3 were met as of ninety days after the end of the Depositor’s most recently ended fiscal year.

(v) The Time of Sale Information, at the Time of Sale (including any Time of Sale Information existing at any Subsequent Time of Sale, if any, at such Subsequent Time of Sale), did not, and at the Closing Date will not, contain any untrue statement of a material fact or omit 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; provided that the Depositor makes no representation and warranty with respect to (A) any statements or omissions made in reliance upon and in conformity with the Underwriter Information, (B) any Mortgage Loan Seller Information contained in or omitted from such Time of Sale Information, (C) any Transaction Party Information contained in or omitted from such Time of Sale Information, (D) any Rialto Information contained in or omitted from such Time of Sale Information or (E) any TPP Information contained in or omitted from such Time of Sale Information.

writing prospectus”, as defined in Rule 433(h) under the 1933 Act, being referred to as an “Issuer Free Writing Prospectus”). Each Issuer Free Writing Prospectus complied or, if used after the date hereof, will comply, in all material respects with the 1933 Act and the rules and regulations promulgated thereunder, has been filed or will be filed in accordance with Section 4 hereof (to the extent required thereby) and did not at the Time of Sale, and at the Closing Date will not, contain any untrue statements of a material fact or (when read in conjunction with the other Time of Sale Information conveyed to the subject investor) omit 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, or include any information that conflicted or conflicts with the information contained in the Registration Statement; provided that the Depositor makes no representation and warranty with respect to (i) any statements or omissions made in reliance upon and in conformity with the Underwriter Information, (ii) any Mortgage Loan Seller Information contained in or omitted from any Issuer Free Writing Prospectus, (iii) any Transaction Party Information contained in or omitted from any Issuer Free Writing Prospectus, (iv) any Rialto Information contained in or omitted from any Issuer Free Writing Prospectus or (v) any TPP Information contained in or omitted from any Issuer Free Writing Prospectus.

The Depositor acknowledges that the Additional FWPs and the other Free Writing Prospectuses filed by it through the date hereof are the only Issuer Free Writing Prospectuses (as defined below) prepared by or on behalf of the Depositor as of the date hereof.

(vii) The Depositor has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware with full power and authority to own its properties and conduct its business, as described in the Prospectus, and to enter into and perform its obligations under this Agreement, the MLPAs and the PSA, and is conducting its business so as to comply in all material respects with all applicable statutes, ordinances, rules and regulations of the jurisdictions in which it is conducting business.

(ix) No stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending or, to the Depositor’s knowledge, threatened by the Commission. The Depositor has not received and is not aware of any request by the Commission for any further amendment of the Registration Statement or the Prospectus or for any additional information or any notification with respect to the suspension of the qualification of the Offered Certificates

for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(x) The issuance and sale of the Certificates, the execution, delivery and performance of this Agreement, the PSA and the MLPAs by the Depositor and the consummation of the transactions contemplated herein and therein by the Depositor and compliance by the Depositor with its obligations hereunder and thereunder have been duly authorized by all necessary corporate action and will not (A) contravene any provision of the certificate of incorporation or by-laws of the Depositor or applicable law or (B) conflict with or constitute a breach of or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Depositor pursuant to, any contract, indenture, mortgage, loan agreement, note, lease or other instrument to which the Depositor or any of its subsidiaries is a party or by which it may be bound or to which any of the property or assets of the Depositor is subject, which conflict, breach, default, lien, charge or encumbrance is reasonably likely to materially and adversely affect the Depositor’s ability to perform its obligations under this Agreement, the MLPAs or the PSA, or any statute, order, decree, rule or regulation applicable to the Depositor or any of its subsidiaries of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Depositor or any of its subsidiaries. Neither the Depositor nor any of its subsidiaries is a party to, bound by or in breach or violation of any indenture or other agreement or instrument, or subject to or in violation of any statute, order, decree, rule or regulation of any court, regulatory body, administrative agency or governmental body having jurisdiction over it, which materially and adversely affects the ability of the Depositor to enter into or perform its obligations under this Agreement, any MLPA or the PSA.

(xi) The Offered Certificates have been duly and validly authorized by the Depositor for issuance and sale (or will have been so authorized prior to the issuance thereof) pursuant to this Agreement and the PSA. When issued, authenticated and delivered by the Certificate Administrator pursuant to the provisions of this Agreement and of the PSA against payment of the consideration therefor by the Underwriters in accordance with this Agreement, the Offered Certificates will be duly and validly issued and outstanding and entitled to the benefits provided by the PSA, except as the enforceability thereof may be limited by the effect of (A) bankruptcy, insolvency, reorganization, receivership, moratorium or other similar laws affecting the enforcement of the rights of creditors generally, and (B) general principles of equity, whether enforcement is sought in a proceeding in equity or at law. The Offered Certificates, the PSA, the MLPAs and the other transaction documents conform in all material respects to all statements relating thereto contained in each of (A) the Prospectus, (B) the Time of Sale Information and (C) any Issuer Information (as may have been revised and corrected if such revised or corrected information was delivered a reasonable time prior to the Time of Sale) delivered to any Underwriter for inclusion in an Underwriter Free Writing Prospectus.

(xii) No authorization, approval or consent of any court or governmental authority or agency is necessary in connection with the offering, issuance or sale of the Offered Certificates hereunder, except such as have been, or as of the Closing Date will have been, obtained or such as may otherwise be required under applicable state securities

laws in connection with the purchase and offer and sale of the Offered Certificates by the Underwriters and any recordation of the respective assignments of the Mortgage Loans to the Trustee pursuant to the MLPAs and the PSA that have not yet been completed.

(xiii) This Agreement and each MLPA have been, and, as of the Closing Date, the PSA will be, duly authorized, executed and delivered by the Depositor. This Agreement and the MLPAs constitute, and as of the Closing Date the PSA will constitute, a legal, valid and binding agreement enforceable against the Depositor in accordance with its terms, except as such enforceability may be limited by the effect of (A) bankruptcy, insolvency, reorganization, receivership, moratorium or other similar laws affecting the enforcement of the rights of creditors generally, (B) general principles of equity, whether enforcement is sought in a proceeding in equity or at law, and (C) public policy considerations underlying the securities laws, to the extent that such public policy considerations limit the enforceability of the provisions of this Agreement that purport or are construed to provide indemnification from securities law liabilities.

(xiv) As of the Closing Date, the representations and warranties of the Depositor set forth in the PSA and any MLPA will be true and correct.

(xv) There are no contracts, indentures or other documents of a character required by the 1933 Act or by the rules and regulations thereunder to be described or referred to in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that have not been so described or referred to therein or so filed or incorporated by reference as exhibits thereto.

(xvi) Immediately prior to the assignment of the Mortgage Loans to the Trustee, the Depositor will have good title to, and will be the sole owner of, each Mortgage Loan free and clear of any pledge, mortgage, lien, security interest, adverse claim or other encumbrance of any other person. At the time of the execution and delivery of the PSA, the Depositor (A) will convey to the Trustee, or cause to be conveyed to the Trustee, all of the Depositor’s right, title and interest in and to the Mortgage Loans, free and clear of any lien, mortgage, pledge, charge, encumbrance, adverse claim or other security interest (collectively, “Liens”) granted by or imposed upon the Depositor, (B) will not have assigned to any other person any of its right, title or interest in the Mortgage Loans or in the PSA or, except for the Underwriters, the Offered Certificates, and (C) will have the power and authority to transfer or cause to be transferred its right, title and interest in the Mortgage Loans to the Trustee and to sell the Offered Certificates to the Underwriters. Upon execution and delivery of the PSA by the Trustee, the Trustee will have acquired ownership of all of the Depositor’s right, title and interest in and to the Mortgage Loans except to the extent disclosed in the Prospectus, and upon delivery to the Underwriters of the Offered Certificates pursuant hereto, each Underwriter will have good title to the Offered Certificates purchased by such Underwriter, in each case free of Liens granted by or imposed upon the Depositor.

(xvii) The PSA is not required to be qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Depositor is not, and the issuance and sale of the Offered Certificates in the manner contemplated by the Prospectus

will not cause the Depositor or the Trust Fund to be, subject to registration or regulation as an “investment company” under the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust Fund will be relying on an exclusion or exemption from the definition of “investment company” under the 1940 Act contained in Section 3(c)(5) of the 1940 Act or Rule 3a-7 under the 1940 Act, although there may be additional exclusions or exemptions available to the Trust Fund. The Trust Fund will not be relying on an exclusion or exemption under Section 3(c)(1) or Section 3(c)(7) of the 1940 Act as a basis for not registering under the 1940 Act. The Trust Fund is being structured so as not to constitute a “covered fund” for purposes of Section 619 of the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act, Pub. L. No. 111-203, 124 Stat. 1376 (2010), also known as the Xxxxxxx Rule.

(xviii) Under generally accepted accounting principles (“GAAP”) 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 Offered 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 Offered Certificates to the Underwriters will constitute at least reasonably equivalent value and fair consideration for the Offered Certificates. The Depositor will be solvent at all relevant times prior to, and will not be rendered insolvent by, the sale of the Offered Certificates to the Underwriters. The Depositor is not selling the Offered Certificates to the Underwriters with any intent to hinder, delay or defraud any of the creditors of the Depositor.

(xix) The Depositor has not relied on the Underwriters for any tax, regulatory, accounting or other advice with respect to compliance with or registration under any statute, rule or regulation of any governmental, regulatory, administrative or other agency or authority. The Depositor acknowledges and agrees that (i) the terms of this Agreement and the offering (including the price of the Offered Certificates) were negotiated at arm’s length between sophisticated parties represented by counsel; (ii) no fiduciary, advisory or agency relationship between the Depositor and the Underwriters has been 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 Offered Certificates are set forth in this Agreement in their entirety; and (iv) it has obtained such legal, tax, accounting and other advice as it deems appropriate with respect to this Agreement and the transactions contemplated hereby and any other activities undertaken in connection therewith, and it is not relying on the Underwriters with respect to any such matters.

(xx) The Trust Fund (other than those portions specified in the PSA) will qualify as two separate real estate mortgage investment conduits (each, a “REMIC”) for federal income tax purposes pursuant to Section 860D of the Internal Revenue Code of 1986, as amended (the “Code”); the Regular Certificates and the VRR REMIC Regular Interest will constitute “regular interests” in a REMIC; and the Class R Certificates will constitute the sole class of “residual interests” in each of the Upper-Tier REMIC and the Lower-Tier REMIC. The Grantor Trust will be treated as a grantor trust under Subpart E

(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 1934 Act, such Corrected Supplement to such investor;

(C) Provide each applicable investor with an opportunity to enter into a new contract of sale on the terms described in the Time of Sale Information (as updated by such Corrected Supplement); and

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

(xiii) (A) If the Depositor becomes aware that, as of the Time of Sale or as of the Closing Date, any information in an Issuer Free Writing Prospectus or any Issuer Information contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements contained therein (when read in conjunction with the Time of Sale Information), in the light of the circumstances under which they were made, not misleading, or conflicted or conflicts with the information contained in the Registration Statement (a “Defective Issuer Free Writing Prospectus”), the Depositor shall notify the Underwriters of such untrue statement or

omission or conflict within one business day after discovery and the Depositor shall, if requested by the Underwriters, prepare and deliver to the Underwriters a Free Writing Prospectus that corrects the material misstatement, omission or conflict in the Defective Issuer Free Writing Prospectus (such corrected Issuer Free Writing Prospectus, a “Corrected Issuer Free Writing Prospectus”).

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

(1) if the Defective Free Writing Prospectus was an Underwriter Free Writing Prospectus (and the defective information does not constitute Issuer Information), prepare a Free Writing Prospectus 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”); provided that if an Underwriter Free Writing Prospectus and Issuer Free Writing Prospectus are both determined to be a Defective Free Writing Prospectus as a result of the same untrue statement or omission in each such document, then the Issuer shall prepare a single Corrected Free Writing Prospectus correcting both such Defective Free Writing Prospectuses;

(2) either (i) deliver the Corrected Free Writing Prospectus to each investor that 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, and (x) notify in writing each such investor in a prominent fashion that the prior contract of sale with such investor has been terminated, and of the investor’s rights as a result of termination of such agreement, and (y) provide each such investor with an opportunity to affirmatively agree to purchase the Offered Certificates on the terms described in the Corrected Free Writing Prospectus; and

(3) 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 the Commission’s Securities Offering Reform Release No. 33-8591.

(D) If the Defective Free Writing Prospectus was an Issuer Free Writing Prospectus (and the Defective Free Writing Prospectus was not defective based solely on an untrue statement or omission in Underwriter Information), 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 Depositor agrees to reimburse the Underwriters for such costs; provided that, before incurring such costs, the Underwriters first permit the Depositor access to the applicable investor and an opportunity to attempt to mitigate such costs through direct negotiation with such investor.

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

5. Covenants of the Depositor.

The Depositor covenants with each Underwriter as follows:

(a) The Depositor will give each of the Underwriters prior written notice of its intention to prepare, use, authorize, approve, refer to or file any Issuer Free Writing Prospectus or to file or prepare (i) any amendment to the Registration Statement at any time prior to the Closing Date or (ii) any amendment or supplement to the Preliminary Prospectus or Prospectus (including any revised prospectus that the Depositor proposes for use by the Underwriters in connection with the offering of the Offered Certificates and that differs from the prospectus on file at the Commission at the time the Registration Statement became effective, whether or not such revised prospectus is required to be filed pursuant to Rule 424(b) under the 1933 Act) at any time during the period during which a prospectus is required to be delivered to purchasers of the Offered Certificates under the 1933 Act (the “Prospectus Delivery Period”), and the Depositor will furnish the Underwriters with copies of any such Issuer Free Writing Prospectus, amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such amendment or supplement or use any such prospectus to which the Underwriters shall reasonably object.

(b) The Depositor will promptly give each Underwriter written notice of (i) when any amendment to the Registration Statement has become effective (subject to paragraph (a) of this Section 5), (ii) any request by the Commission for any amendment of the Registration Statement or the Prospectus or for any additional information relating to the Depositor or the Offered Certificates, (iii) any written notification received by the Depositor of suspension of qualification of the Offered Certificates for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (iv) the issuance by the Commission of any stop order

suspending the effectiveness of the Registration Statement or the institution or, to the knowledge of the Depositor, threatening any proceeding for that purpose. The Depositor will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) If, at any time during the Prospectus Delivery Period any event occurs as a result of which the Preliminary Prospectus (as then amended or supplemented) or the Prospectus (as then amended or supplemented) would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend or supplement the Registration Statement, or the Prospectus to comply with the 1933 Act or the rules under the 1933 Act, the Depositor promptly will prepare and file with the Commission an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance and, if such amendment or supplement is required to be contained in a post-effective amendment to the Registration Statement, will use its best efforts to cause such amendment of the Registration Statement to be made effective as soon as possible.

(d) The Depositor will cause the Prospectus to be transmitted to the Commission for filing pursuant to Rule 424(b) under the 1933 Act by means reasonably calculated to result in filing with the Commission pursuant to said rule. Subject to Section 4 hereof, the Depositor will cause the Issuer Free Writing Prospectus to be transmitted for filing pursuant to Rule 433 under the 1933 Act by means reasonably calculated to result in filing with the Commission pursuant to said rule.

(e) The Depositor will furnish to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including exhibits thereto) and each amendment and supplement thereto that shall become effective on or prior to the Closing Date and, during the Prospectus Delivery Period, as many copies of the Prospectus and any amendments and supplements thereto as the Underwriters may reasonably request. Prior to the date on which the Prospectus is available, the Depositor will furnish to the Underwriters and each counsel for the Underwriters, without charge as many copies of the Preliminary Prospectus and each Issuer Free Writing Prospectus as the Underwriters may reasonably request.

(f) The Depositor will furnish such information, execute such instruments and take such action, if any, as may be required to qualify the Offered Certificates for sale under the laws of such jurisdictions as the Underwriters may reasonably designate and will maintain such qualification in effect so long as required for the initial distribution of Offered Certificates; provided, that the Depositor shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file a general consent to service of process in any jurisdiction.

(g) The Depositor will use the net proceeds received by it from the sale of the Offered Certificates in the manner specified in the Preliminary Prospectus and the Prospectus under “USE OF PROCEEDS.”

(h) Whether or not the transactions contemplated in the PSA are consummated or this Agreement is terminated, the Depositor will pay or cause to be paid all expenses incident

to the performance of the obligations of the Depositor under this Agreement, including, without limitation, (i) the fees, disbursements and expenses of the Depositor’s counsel and accountants in connection with the purchase and transfer of the Mortgage Loans and the issuance and sale of the Offered Certificates, (ii) the costs and expenses of preparing and delivering the PSA, the MLPAs and the other transaction documents to the parties thereto, (iii) the fees, costs and expenses of the Trustee, the Custodian and the Certificate Administrator (to the extent not otherwise payable under the PSA, and except to the extent that another party is obligated to pay such amounts thereunder), (iv) all fees and expenses incurred in connection with the registration and delivery of the Offered Certificates under the 1933 Act, and all other fees or expenses in connection with the preparation and filing of the Registration Statement, the Time of Sale Information, any Issuer Free Writing Prospectus, the Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities specified above, (v) the costs of printing or producing any “blue sky” memorandum in connection with the offer and sale of the Offered Certificates under state securities laws and all expenses in connection with the qualification of the Offered Certificates for the offer and sale under state securities laws as provided in Section 5(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the “blue sky” memorandum, (vi) the cost of printing the Offered Certificates, (vii) all costs and expenses related to the transfer and delivery of the Offered Certificates to the Underwriters, including any transfer or other taxes payable thereon, (viii) the upfront costs and charges of any custodian, transfer agent, registrar or depository (to the extent not otherwise payable under the PSA, and except to the extent that another party is obligated to pay such amounts pursuant to an agreement executed in connection with the issuance of the Certificates), (ix) the fees and expenses of the rating agencies incurred in connection with the issuance and sale of the Offered Certificates; and (x) all other costs and expenses incident to the performance of the obligations of the Depositor hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in Section 7 hereof or as otherwise agreed to by the parties, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel.

(i) The Depositor shall obtain a letter from a nationally recognized certified public accounting firm (reasonably satisfactory to the Underwriters), satisfactory in form and substance to the Depositor and the Underwriters, to the effect that such accounting firm has performed certain specified procedures, all of which have been agreed to by the Depositor and the Underwriters, as a result of which it has determined that the information included in the Time of Sale Information and the Prospectus that such accounting firm has examined in accordance with such agreed upon procedures, is accurate except as to such matters that are not deemed by the Depositor or the Underwriters to be material.

(j) The Depositor acknowledges and agrees that each Underwriter in providing investment banking services to the Depositor in connection with the offering, including in acting pursuant to the terms of this Agreement, has acted and is acting as an independent contractor and not as a fiduciary and the Depositor does not intend such Underwriter to act in any capacity other than independent contractor, including as a fiduciary or in any other position of higher trust.

(k) The Depositor will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus or any materials used in a Road Show

(as defined in Rule 433 of the 1933 Act) that are required to be retained by the Depositor pursuant to the 1933 Act, to the extent not filed with the Commission in accordance with Rule 433 under the 1933 Act.

6. Conditions of Underwriters’ Obligations.

This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have.

(c) Each Underwriter (the “Indemnifying Underwriter”) shall indemnify and hold harmless the other Underwriters, their respective officers and directors, and each person, if any, who controls either such other Underwriter within the meaning of either the 1933 Act or the 1934 Act (each such other Underwriter and its related officers, directors and controlling persons, collectively, a “Non-Indemnifying Underwriter”) from and against any and all Liabilities, joint or several, to which any such Non-Indemnifying Underwriter becomes subject under the 1933 Act, the 1934 Act or otherwise, insofar as such 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 regarding the Indemnifying Underwriter contained in the Underwriter Information, or the omission or alleged omission to state a material fact necessary in order to make the statements regarding the Indemnifying Underwriter contained in the Underwriter Information, in the light of the circumstances under which they were made, not misleading, (ii) any untrue statement or alleged untrue statement of a material fact, or the omission or alleged omission (when read in conjunction with the Time of Sale Information) to state a material fact 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 or any other Free Writing Prospectus described in Section 4(vii) or (viii) hereof, in each case that was prepared (or, if not prepared by any Underwriter, was used, authorized or approved) by or on behalf of the Indemnifying Underwriter(s), or (iii) the failure of such Indemnifying Underwriter, or any member of its selling group, to comply with any provision of Sections 1(c)(v), (vi) and (viii), 2 and 4 hereof, and agrees to reimburse any 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; provided that the Indemnifying Underwriter(s) shall not be liable under this subsection (c) to any Non-Indemnifying Underwriter in respect thereof to the extent that the Non-Indemnifying Underwriter is entitled to indemnification or contribution for the subject loss, claim, damage, liability cost or expense (i) from another party pursuant to any separate indemnification agreement entered into by a Mortgage Loan Seller, a Transaction Party, Rialto or the TPP in favor of such Underwriter, or (ii) from the Depositor hereunder. No Underwriter shall be liable to another Underwriter or any officer, director or controlling person with respect to such other 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) Each indemnified party shall give notice in writing as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than under subsection (a), (b) or (c) of this Section 7. Upon request of the indemnified party, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified 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. If any action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party may participate at its own expense in the defense of any such action. The indemnifying party may elect to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from the indemnified party. 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, (iii) the indemnified party 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 party, or (iv) 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 as incurred by the indemnifying 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,

and all such fees and expenses shall be reimbursed as they are incurred. 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. 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 sentence, 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 subsection, 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 30 days after receipt by such indemnifying party of the aforesaid request, and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. 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 provides for an unconditional release of the indemnified party, in form and substance satisfactory to such indemnified party, and without any admission of fault, culpability or failure to act or on behalf of the indemnified party, from all liability on claims that are the subject matter of such proceeding, without the consent of the indemnified party.

(e) If the indemnification provided for in subsection (a), (b) or (c) of this Section 7 is applicable in accordance with its terms with respect to one or more indemnifying parties, but is for any reason unavailable or insufficient to hold harmless an indemnified party under such subsection (a), (b) or (c) above, then in order to provide for just and equitable contribution, each such indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the Liabilities referred to in such subsection (a), (b) or (c) above in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other from the offering of the Offered Certificates or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party or parties on the other in connection with the untrue statements or omissions or alleged untrue statements or omissions that resulted in such Liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Depositor on the one hand and an Underwriter on the other shall be deemed to be in the same proportion as the total proceeds from the issuance and sale of the Offered Certificates under this Agreement (before deducting expenses) received by the Depositor bear to the total underwriting discounts, commissions or other fees received by such Underwriter. The relative benefits received by an Underwriter on the one hand and another Underwriter on the other shall be deemed to be in the same proportion as the total underwriting discounts, commissions or other fees received by the first such Underwriter bear to the total underwriting discounts, commissions or other fees received by the other such Underwriter. The relative fault of the parties shall be determined by reference to, among other things, if and to the extent applicable, 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 supplied by the indemnifying party on the one hand, or the indemnified party on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission.

(f) The parties hereto agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation that does not take account of the considerations referred to in subsection (e) above. The amount paid or payable by an indemnified party as a result of the 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, subject to the limitations provided in subsection (e) above. If 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. Notwithstanding the provisions of subsection (e) above or this subsection (f), no Underwriter shall be required to contribute or deemed to contribute any amount in excess of the amount by which (i) the total underwriting discounts and commissions and other fees received by such Underwriter in connection with the offering of the Offered Certificates exceeds (ii) 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. 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 subsection (f), 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 subsection (f).

(g) No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 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.

(h) The indemnity and contribution agreements contained in this Section 7 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by the Depositor, an Underwriter, any of their respective directors or officers, or any person controlling the Depositor or such Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, and (iii) acceptance of and payment for any of the Offered Certificates.

(i) The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective amount of Offered Certificates they have purchased hereunder, and not joint.

8. Certain Provisions to Survive Delivery.

The respective indemnities, agreements, representations, warranties and other statements of the Depositor, MSMCH and the Underwriters as set forth in this Agreement shall remain in full force and effect, regardless of any investigations (or any statements as to the results thereof) made in connection with the issuance of Certificates by or on behalf of the Underwriters or any officer or director or controlling person of an Underwriter, or the Depositor or MSMCH, or any officer, director or controlling person of the Depositor or MSMCH and shall survive delivery of and

payment for the Certificates. The provisions of Sections 5(h), 7 and 10(c) hereof shall survive the termination or cancellation of this Agreement.

9. Defaulting Underwriter.

(a) If, on the Closing Date, any of the Underwriters shall fail or refuse to purchase Offered Certificates that it has agreed to purchase hereunder on such date, and the aggregate principal amount of Offered Certificates which such defaulting Underwriter agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Offered Certificates to be purchased on such date, each other Underwriter shall be obligated to purchase a pro rata portion (based on the allocation set forth on Schedule I) of the Offered Certificates which such defaulting Underwriter agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Offered Certificates that any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Offered Certificates, without the written consent of such Underwriter, and provided, further, that no Underwriter shall be obligated under this Section 9 to purchase Offered Certificates of a Class that it is not otherwise obligated to purchase under this Agreement.

(b) If, on the Closing Date, one of the Underwriters shall fail or refuse to purchase Offered Certificates that it has agreed to purchase hereunder on such date and the aggregate principal amount of Offered Certificates with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Offered Certificates to be purchased on such date and arrangements satisfactory to the non-defaulting Underwriters and the Depositor for the purchase of such Offered Certificates are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or of the Depositor. In any such case any such non-defaulting Underwriter or the Depositor shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Prospectus or in any other documents or arrangements may be effected. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. Termination of Agreement.

(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 Offered Certificates provided for herein is not consummated because of any failure or refusal on the part of the Depositor to comply in all material respects with the terms, or to fulfill in all material respects any of the conditions of, this Agreement (including if any of the opinions and certificates mentioned in Section 6 hereof or elsewhere in this Agreement shall not be in all material respects satisfactory in form and substance to the Underwriters and counsel for the Underwriters), or if for any reason the Depositor shall be unable to perform in all material respects its obligations under this Agreement.

(b) The obligations of the Underwriters to purchase the Offered Certificates shall be terminable by the Underwriters, in the absolute discretion of the Underwriters, by notice given to the Depositor and MSMCH, if at any time on or prior to the delivery of and payment for the Offered Certificates (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 Fund which, in the judgment 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 Offered Certificates, (ii) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, or the over-the-counter market, or minimum prices shall have been established on any such exchange, (iii) trading of any securities of the Depositor or its affiliates shall have been suspended on any exchange or in any over-the-counter market, (iv) any downgrading in the intended rating of any of the Offered Certificates by any Rating Agency shall have occurred, or any such ratings shall have been withdrawn, suspended or qualified, (v) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or State of New York authorities, or (vi) there shall have occurred any attack, outbreak or escalation of hostilities or any act of terrorism, or any change in financial markets or any calamity or crisis, or any major disruption of settlement or clearance of securities in the United States that, in the judgment of such Underwriter, is material and adverse and, in the case of any of the events specified in the immediately preceding clauses (i) through (vi), such event singly or together with any other such event, makes it, in the judgment of the Underwriters, impracticable to market the Offered Certificates on the terms and in the manner contemplated in the Time of Sale Information and the Prospectus.

(c) If any Underwriter terminates its obligations under this Agreement in accordance with Section 10(a), the Depositor shall reimburse such Underwriter upon demand 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 Offered Certificates.
