Ladies and Gentlemen:

By this letter agreement (this “Letter Agreement”), we are pleased to confirm the terms and conditions under which Merrill Lynch, Pierce, Fenner & Smith Incorporated (together with our subsidiaries and affiliates, “MLPF&S”) will act as sole lead underwriter for RWT Holdings, Inc. (the “Company”), a wholly-owned subsidiary of Redwood Trust, Inc. (“Redwood Trust,” and together with the Company and their subsidiaries and affiliates, “Redwood”) in connection with the proposed offer and sale (together, the “Offering”) of certain classes of mortgage-backed securities (the “2013-8 Securities”) issued by Sequoia Mortgage Trust 2013-8 (the “Issuing Entity” and such issuance, the “Transaction”). The Issuing Entity is expected to issue (i) one or more classes of senior certificates entitled to payments of both interest and principal that will be rated AAA or its equivalent by two of Moody’s Investors Service, Inc., Fitch Ratings, Inc. or Standard &  Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business (each, a “Rating Agency” and such 2013-8 Securities, “AAA P&I Senior Securities”), (ii) one or more classes of senior certificates entitled to interest-only payments that will be rated AAA or its equivalent by two of the Rating Agencies (“AAA IO Senior Securities”), (iii) one or more classes of subordinate certificates (the “Subordinate Securities”) and (iv) one or more classes of REMIC residual certificates.

1.                  The 2013-8 Securities are expected to be secured by a single pool of mortgage loans (the “Mortgage Loans”). A loan tape (the “Initial Tape”) containing information regarding the Mortgage Loans was furnished by Redwood to MLPF&S on May 21, 2013, and the final balance will be subject to the related Loan Balance Permitted Variance specified on Annex A from the balance shown on the Initial Tape.

Redwood may substitute up to an aggregate of the Permitted Substitution Percentage specified on Annex A hereto (calculated by balance) of the Initial Tape so long as (a) there are no material differences between the attributes of the Mortgage Loans after substitution and the attributes reflected in the Initial Tape that would materially change the AAA P&I Senior Securities credit enhancement level specified in Section 3 and (b) the Loan Balance Permitted Variance is maintained after taking account of the related substitutions.

At its sole expense, MLPF&S shall conduct a customary underwriter’s due diligence review of all of the Mortgage Loans and shall have the right, in its reasonable discretion, to have certain loans removed from the final pool of Mortgage Loans based on its due diligence results.

2.                  Structure of the Transaction; Documentation. The Transaction shall be structured in a manner substantially similar in all material respects to previous securitization transactions of fixed rate pools executed by Redwood under the “Sequoia Mortgage Trust” program (the “SEMT Program”) including, but not limited to, the same “shifting interest” provisions and mechanics in the securitization transaction in the SEMT Program that closed on April 30, 2013 (“SEMT 2013-6”) with respect to the fixed rate pool included therein. Additionally, the disclosures included in the SEMT 2013-8 securitization shall be similar to those in SEMT 2013-6. Such disclosures shall also include a Rule 424(b) filing made following confirmation of the preliminary engagement substantially in the form previously provided to MLPF&S, but with such changes are necessary or desirable to reflect the terms of this Letter Agreement. In connection therewith, Redwood Residential Acquisition Corporation (in such capacity, the “Seller”) shall transfer the Mortgage Loans to either Sequoia Mortgage Funding Corporation or Sequoia Residential Funding, Inc., which shall act as depositor (the “Depositor”) for the Transaction. The transaction documents governing (i) the sale of the Mortgage Loans from the Seller to the Depositor, (ii) the sale of the Mortgage Loans from the Depositor to the Issuing Entity or the trustee (the “Trustee”) of the Issuing Entity and the issuance and terms of the 2013-8 Securities, (iii) the servicing and administration of the Mortgage Loans by each servicer (each, a Servicer”) and supervision thereof by the master servicer (the “Master Servicer”), (iv) the custody of the Mortgage Loan files by the custodian (the “Custodian”) and (v) the assignment of representations and warranties (together, the “Basic Transaction Documents”), shall be substantially similar in all material respects to the transaction documents executed in connection with the SEMT 2013-6 transaction.

3.                  Ratings. It is a condition to the consummation of the Transaction that at least two Rating Agencies selected by Redwood (the “Initial Rating Agencies”) issue a AAA or equivalent rating in respect of the AAA P&I Senior Securities. The fees of the Initial Rating Agencies shall be paid in accordance with Section 8 hereof. Notwithstanding any Rating Agency feedback in respect of an AAA or equivalent rating, the Initial Credit Enhancement for the AAA P&I Senior Securities shall be specified on Annex A.

4.                  Underwriting Arrangement. MLPF&S shall act as sole lead underwriter (the “Underwriter”) for the Offering of each class of AAA P&I Senior Securities. MLPF&S will have the option, in its sole discretion, to strip off of the AAA P&I Senior Securities one or more interest only certificates, which will have the same interest priority as the AAA P&I Senior Securities and which may be rated AAA or its equivalent by two Rating Agencies (the “Underwritten AAA IO Senior Securities,” and together with the AAA P&I Senior Securities, the “Underwritten Senior Securities”); provided, that the aggregate interest on the Underwritten Senior Securities does not exceed the Underwritten Senior Securities Interest Rate specified in Annex A. Promptly after execution of this Letter Agreement, MLPF&S and Redwood shall cooperate and work in good faith to negotiate an underwriting agreement (when executed and delivered by the parties, the “Underwriting Agreement”) in respect of the Underwritten Senior Securities substantially similar in all material respects to the underwriting agreement executed in connection with the SEMT 2013-6; provided that the MLPF&S shall receive a representation from the Company as to compliance with the requirements of paragraph (a) (b) (c) of Rule 17g-5 of the Exchange Act. It is expected that MLPF&S shall purchase Underwritten Senior Securities in an aggregate principal amount equal to the Underwritten Senior Securities Balance specified on Annex A, subject to the Underwritten Senior Balance Permitted Variance specified on Annex A, for a purchase price equal to the product of (i) the Initial Purchase Price Percentage specified on Annex A, adjusted to reflect the Securities Price Adjustment described in Section 9, and (ii) the actual Underwritten Senior Securities Balance as of the date of the closing of the Transaction (the “Closing Date”); provided, that at Redwood’s sole option, a variance of greater than the positive Underwritten Senior Securities Balance Permitted Variance in the principal amount of the AAA P&I Senior Securities shall be permitted solely to the extent that Redwood purchases the AAA P&I Senior Securities in excess of such variance. The Underwritten Senior Securities Interest Rate on the AAA P&I Senior Securities (without taking into account any Underwritten AAA IO Senior Securities) shall be specified on Annex A. MLPF&S shall be entitled to receive the additional fees or discounts from Redwood in respect of the Underwritten Senior Securities as described under “Additional Fees or Discounts” specified on Annex A. Additionally, MLPF&S acknowledges that, subsequent to the Closing Date, any securities retained by Redwood or any of its affiliates may be placed by a different underwriter or placement agent.

5.                  Retention of Certain 2013-8 Securities by Redwood. Redwood shall initially retain (i) the AAA IO Senior Securities that are not Underwritten AAA IO Senior Securities and (ii) the Subordinate Securities (the “Redwood Retained Securities”) issued by the Issuing Entity.

6.                  Underwriting Fee for Subordinate Securities. In the event that Redwood decides to offer any of the Subordinate Securities under the Underwriting Agreement (such Subordinate Securities, the “Underwritten Subordinate Securities,” and together with the Underwritten Senior Securities, the “Underwritten Securities”), MLPF&S shall receive an underwriting fee calculated as the product of (i) the Subordinate Securities Underwriting Fee Percentage specified on Annex A and (ii) the unpaid principal balance of Underwritten Subordinate Securities as of the Closing Date (the “Subordinate Securities Underwriting Fee”).

MLPF&S will have sole discretion to determine the price at which each class of Underwritten Senior Securities may be offered to third parties or purchased by MLPF&S; provided that such prices allow all the Underwritten Senior Securities to be sold to third party investors or MLPF&S; provided further that Redwood may opt to purchase any or all of each class of Underwritten Senior Securities at such price in lieu of MLPF&S's sale of the same to either a third party or to itself. Furthermore, if Redwood elects to purchase any Underwritten Senior Securities, then Redwood shall not offer such Underwritten Senior Securities to any third parties until after the Closing Date.

In connection with the Offering and as described in greater particularity in the Underwriting Agreement, MLPF&S shall (a) prepare the term sheet and (b) generate all collateral and yield tables, in each case based on information provided to MLPF&S by Redwood. In addition, MLPF&S shall obtain comfort letters from the hired accounting firm in respect of the documents and/or information specified in (a) and (b), which shall be addressed to both MLPF&S and Redwood. The Underwriting Agreement shall govern any required indemnification by MLPF&S or Redwood in respect of the Offering Documents prepared by Redwood and the documents and/or information specified in (a) and (b) prepared by MLPF&S and will be substantially similar in all material respects to the indemnification provisions included in the SEMT 2013-6 transaction.

9.                  Closing of the Transaction; Delay Penalty. MLPF&S and Redwood shall make all commercially reasonable efforts to close the Transaction on the Targeted Closing Date specified on Annex A. If the Transaction does not close on the Targeted Closing Date, MLPF&S and Redwood shall make all commercially reasonable efforts to close the Transaction as soon as practicable thereafter but not later than the Latest Permitted Closing Date specified on Annex A.

To the extent that the Transaction does not close on the Targeted Closing Date but closes on or before the Latest Permitted Closing Date and the failure to close on the Targeted Closing Date is the result of a delay of or caused by Redwood or Rating Agencies in connection with any Offering Document or the Underwriting Agreement, provided that the Underwriter has provided to Redwood all information required to complete such documents no later than five (5) Business Days prior to the Targeted Closing Date, the Initial Purchase Price Percentage shall be reduced by the Delay Penalty Percentage specified on Annex A, the (“Securities Price Adjustment”).

(b) Redwood (i) shall make available to MLPF&S marketing materials substantially similar to the marketing materials used for SEMT 2013-6 transaction; (ii) at the request of MLPF&S, provide such information and documents as may be reasonably requested in order to enable MLPF&S to market the Underwritten Securities and carry out the engagement contemplated by this Letter Agreement and the Underwriting Agreement; and (iii) assist MLPF&S in carrying out its duties, functions and responsibilities pursuant hereto and provide reasonable access to the appropriate senior officers, management, accountants, legal counsel and other parties and facilities.

(c) In connection with the Transaction, Redwood has contracted a diligence firm to perform a diligence review of the Mortgage Loans. Redwood agrees to make available the loan-level files and loan-level diligence results of such firm to MLPF&S, in order to enable MLPF&S to conduct and complete its customary due diligence review of the Mortgage Loans. Redwood recognizes and confirms that MLPF&S will be using information in reports and other information provided by others, including, without limitation, information provided by or on behalf of Redwood and the diligence firm contracted by Redwood, and that MLPF&S does not assume responsibility for and may rely, without independent verification, on the accuracy and completeness of any such information.
