Item 1117 of Regulation AB, Legal Proceedings.

On or about December 23, 2009,

There is no significant update regarding the Federal Home Loan Bank of Seattle (the “FHLB-Seattle”) filed a complaintlitigation matters described in the Superior CourtRedwood’s Form 10-K for the State of Washington (case number 09-2-46348-4 SEA) against the depositor, Redwood Trust, Inc. (“Redwood Trust”), Morgan Stanley & Co., and Morgan Stanley Capital I, Inc. (collectively, the “FHLB-Seattle Defendants”), which alleged that the FHLB-Seattle Defendants made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Seattle Certificate”) issued in the Sequoia Mortgage Trust 2005-4 securitization transaction (the “2005-4 RMBS”) and purchased by the FHLB-Seattle. The Seattle Certificate was issued with an original principal amount of approximately $133 million, and, atyear ended December 31, 2019, approximately $128 million2022 under the heading “Item 1117 of principal and $12 million of interest payments had been made in respect of the Seattle Certificate. As of December 31, 2019, the Seattle Certificate had a remaining outstanding principal amount of approximately $6 million. The matter was subsequently resolved and the claims were dismissed by the FHLB-Seattle as to all the FHLB-Seattle Defendants. At the time the Seattle Certificate was issued, the depositor and Redwood Trust agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, the depositor and Redwood Trust could incur a loss as a result of these indemnities.

On or about July 15, 2010, The Charles Schwab Corporation (“Schwab”) filed a complaint in the Superior Court for the State of California in San Francisco (case number CGC-10-501610) against the depositor and 26 other defendants (collectively, the “Schwab Defendants”), which alleged that the Schwab Defendants made false or misleading statements in offering materials for various residential mortgage-backed securities sold or issued by the Schwab Defendants. Schwab alleged only a claim for negligent misrepresentation under California state law against the depositor and sought unspecified damages and attorneys’ fees and costs from the depositor. Schwab claimed that the depositor made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Schwab Certificate”) issued in the 2005-4 RMBS and purchased by Schwab. The Schwab Certificate was issued with an original principal amount of approximately $15 million, and, at December 31, 2019, approximately $14 million of principal and $1 million of interest payments had been made in respect of the Schwab Certificate. As of December 31, 2019, the Schwab Certificate had a remaining outstanding principal amount of approximately $1 million. At the time the Schwab Certificate was issued, the depositor and Redwood Trust agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were also named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, the depositor and Redwood Trust could incur a loss as a result of these indemnities.Regulation AB, Legal Proceedings.”

The business of the sponsor, the depositor, the seller and their affiliates has included, and continues to include, activities relating to the acquisition and securitization of residential mortgage loans. In addition, the business of the sponsor has, in the past, included activities relating to the acquisition and securitization of debt obligations and other assets through the issuance of collateralized debt obligations (commonly referred to as CDO transactions). Because of their involvement in the securitization and CDO businesses, the sponsor, the depositor, the seller and their affiliates could become the subject of litigation relating to these businesses, including additional litigation of the type described above, and could also become the subject of governmental investigations, enforcement actions, or lawsuits and governmental authorities could allege that these entities violated applicable law or regulation in the conduct of their business. As an example, in July 2016 the sponsor, the depositor and their affiliates became aware of a complaint filed by the State of California on April 1, 2016 against Morgan Stanley & Co. and certain of its affiliates alleging, among other things, that there were misleading statements contained in offering materials for 28 different mortgage pass through certificates purchased by various California investors, including various California public pension systems, from Morgan Stanley and alleging that Morgan Stanley made false or fraudulent claims in connection with the sale of those certificates. Of the 28 mortgage pass-through certificates that were the subject of the complaint, two were Sequoia mortgage pass-through certificates issued in 2004 and two were Sequoia mortgage pass-through certificates issued in 2007. With respect to each of those certificates, RWT Holdings, Inc. was the sponsor and Sequoia Residential Funding, Inc. was the depositor. The plaintiffs subsequently withdrew from the litigation their claims based on eight of the 28 mortgage pass-through certificates, including one of the Sequoia mortgage pass-through certificates issued in 2004. We believe this matter was subsequently resolved and the plaintiffs withdrew their remaining claims. At the time these Sequoia mortgage pass-through certificates were issued, the depositor and Redwood Trust agreed to indemnify the underwriters of these certificates for certain losses and expenses they might incur as a result of claims made against them relating to these certificates, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, the depositor and Redwood Trust could incur a loss as a result of these indemnities.

The depositor has been notified by Citibank, N.A. (“Citibank”), Wells Fargo Bank, N.A. (“Wells Fargo”) and U.S. Bank National Association (“U.S. Bank”), respectively, of material pending legal proceedings to which Citibank, Wells Fargo and U.S. Bank are, respectively,is subject in connection with theirits role as trustee on certain RMBS transactions. This Sequoia transaction is not a party to nor subject to the pending legal proceedings.

The disclosure that the depositor received from each of Citibank and Wells Fargo respectively, is included here:

Citibank,

Wells Fargo Bank, N.A.

Citibank, N.A. (“Citibank”) is acting as Securities Administrator of this RMBS transaction.

In the ordinary course of business, Citibank is involved in a number of legal proceedings, including in connection with its role as trustee ofDecember 2014, Phoenix Light SF Limited (Phoenix Light) and certain RMBS transactions. Certain of these Citibank as trustee-related matters are disclosed herein.

On June 18, 2014, a civil action was filed against Citibank in the Supreme Court of the State of New York by a group of investors in 48 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee, asserting claims for purported violations of the Trust Indenture Act of 1939 (the “Trust Indenture Act”), breach of contract, breach of fiduciary duty and negligence based on Citibank’s alleged failure to perform its duties as trustee for the 48 RMBS trusts. On November 24, 2014, plaintiffs sought leave to withdraw this action. On the same day, a smaller subset of similar plaintiff investors in 27 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee,related entities filed a new civil action against Citibankcomplaint in the United States District Court for the Southern District of New York asserting similaralleging claims as the prior action filed in state court. In January 2015, the court closed plaintiffs’ original state court action. On September 8, 2015, the federal court dismissed all claims as to 24 of the 27 trusts and allowed certain of the claims to proceed as to the other three trusts. Subsequently, plaintiffs voluntarily dismissed all claims with respect to two of the three trusts. On April 7, 2017, Citibank filed a motion for summary judgment. Plaintiffs filed its consolidated opposition brief

and cross motion for partial summary judgment on May 22, 2017. Briefing on those motions was completed on August 4, 2017. On March 22, 2018, the court granted Citibank’s motion for summary judgmentagainst Wells Fargo Bank, N.A., in its entirety, denied Plaintiffs’ motion for summary judgment and ordered the clerk to close the case. On April 20, 2018, plaintiffs filed a notice of appeal. Plaintiffs’ opening brief was filed on August 3, 2018. Citibank filed its opposition on November 2, 2018. Plaintiffs’ filed their reply on November 16, 2018. On June 7, 2019, the Second Circuit dismissed plaintiffs’ appeal following the parties’ filing of a stipulation withdrawing the case with prejudice pursuant to Federal Rule of Appellate Procedure 42.

On November 24, 2015, the same investors that brought the federal case brought a new civil action in the Supreme Court of the State of New York related to 25 private-label RMBS trusts for which Citibank allegedly serves or did servecapacity as trustee. This case includes the 24 trusts previously dismissed in the federal action, and one additional trust. The investors assert claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, and violation of New York’s Streit Act (the “Streit Act”). Following oral argument on Citibank’s motion to dismiss, Plaintiffs filed an amended complaint on August 5, 2016. On June 27, 2017, the state court issued a decision, dismissing the Event of Default claims, mortgage-file-related claims, the fiduciary duty claims, and the conflict of interest claims. The decision sustained certain breach of contract claims including the claim alleging discovery of breaches of representations and warranties, a claim related to robo-signing, and the implied covenant of good faith claim. Citibank appealed the lower court’s decision, and on January 16, 2018, the Appellate Division, First Department, dismissed the claims related to robo-signing and the implied covenant of good faith, but allowed plaintiffs’ claim alleging discovery of breaches of representations and warranties to proceed. On June 7, 2019, plaintiffs filed a motion for discontinuance of the action and dismissal of plaintiffs’ claims with prejudice.

On August 19, 2015, the Federal Deposit Insurance Corporation (“FDIC”) as Receivertrustee for a failed financial institutionnumber of residential mortgage-backed securities (RMBS) trusts. Complaints raising similar allegations have been filed a civil action against Citibankby Commerzbank AG in the Southern District of New York. This action relates to one private-label RMBS trust for which Citibank formerly served as trustee. FDIC asserts claims for breach of contract, violation of the Streit Act,York and violation of the Trust Indenture Act. Citibank jointly briefed a motion to dismiss with The Bank ofby IKB International and IKB Deutsche Industriebank in New York Mellon and U.S. Bank, N.A., entitiesstate court. In each case, the plaintiffs allege that have also been sued by FDIC in their capacity as trustee, and these cases have all been consolidated in front of Judge Carter. On September 30, 2016, the Court granted the motion to dismiss without prejudice for lack of subject matter jurisdiction. On October 14, 2016, FDIC filed a motion for reargument or relief from judgment from the Court’s dismissal order. On July 11, 2017, Judge Carter ruled on the motion for reconsideration regarding his dismissal of the action. He denied reconsideration of his decision on standing, but granted leave to amend the complaint by October 9, 2017. The FDIC subsequently requested an extension of time to file its amended complaint, which was granted. The FDIC filed its amended complaint on December 8, 2017. Defendants jointly filed a motion to dismiss the amended complaint and that joint motion was fully briefed as of May 3, 2018. On March 20, 2019, the Court granted defendants’ joint motion to dismiss the amended complaint. The FDIC’s deadline to file a notice of appeal was April 22, 2019. The FDIC has not appealed.

There can be no assurances as to the outcome of litigation or the possible impact of litigation on the trustee or the RMBS trusts. However, Citibank denies liability and continues to vigorously defend against these litigations. Furthermore, neither the above-disclosed litigations nor any other pending legal proceeding involving Citibank will materially affect Citibank’s ability to perform its duties as Securities Administrator under the pooling and servicing agreement for this RMBS transaction.

Wells Fargo Bank, N.A.

Beginning on June 18, 2014, a group of institutional investors filed civil complaints in the Supreme Court of the State of New York, New York County, and later the U.S. District Court for the Southern District of New York, against Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in its capacity as trustee for certain residential mortgage backed securities (“RMBS”) trusts.  The complaints against Wells Fargo Bank alleged that the trustee, caused losses to investors, and assertedplaintiffs assert causes of action based upon, among other things, the trustee'strustee’s alleged failure to: (i)to notify and enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default, and (iii) abide by appropriate standards of care following alleged events of default. Relief sought included money damagesIn July 2022, the district court dismissed Phoenix Light’s claims and certain of the claims asserted by Commerzbank AG, and subsequently entered judgment in an unspecified amount, reimbursementeach case in favor of expenses, and equitable relief. In November 2018, Wells Fargo Bank, reached an agreement, in which it denied any wrongdoing,N.A. In August 2022, Phoenix Light and Commerzbank AG appealed the district court’s decision to resolve such claims on a classwide basisthe United States Court of Appeals for the 271 RMBS trusts at issue.  On May 6, 2019,Second Circuit. The Company previously settled two class actions filed by institutional investors and an action filed by the National Credit Union Administration with similar allegations. In addition, Park Royal I LLC and Park Royal II LLC have filed substantially similar lawsuits in New York state court entered an order approving the settlement agreement.  Separate lawsuits againstalleging Wells Fargo Bank, making similar allegations filed by certain other institutional investors concerning several RMBS trusts in New York federal and state court are not covered by the agreement.  With respectN.A., as trustee, failed to such litigations, Wells Fargo Bank believes plaintiffs' claims are without merit and intends to contest the claims vigorously, but there can be no assurances as to the outcometake appropriate actions upon learning of the litigations or the possible impact of the litigations on Wells Fargo Bank or the RMBS trusts.defective mortgage loan documentation.

Item 1119 of Regulation AB, Affiliations and Certain Relationships and Related Transactions.

The seller and servicing administrator, the sponsor and the depositor are each either directly or indirectly wholly-owned subsidiaries of Redwood Trust, Inc. There is not currently, and there was not during the past two years, any material business relationship, agreement, arrangement, transaction or understanding that is or was entered into outside the ordinary course of business or is or was

on terms other than would be obtained in an arm’s length transaction with an unrelated third party, between (a) any of the seller, the sponsor, the depositor and the issuing entity on the one hand and (b) any of the trustee, any servicer, the custodian, the master servicer, the securities administrator or either originator of the mortgage loans on the other hand.

Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.

The reports on assessment of compliance with the servicing criteria for asset-backed securities and the related attestation reports on such assessments of compliance are attached hereto under Item 15.

The registrant has prepared the Table below in connection with this transaction. The Table shows, in one compiled format, which entity participating in a servicing function for this transaction was assigned responsibility for each criterion in Item 1122(d). In the Table below, certain criteria are not applicable, given the structure of the offering, and accordingly no entity is assigned responsibility for such criteria.

On November 1, 2021, Wells Fargo transferred substantially all of its Corporate Trust Services business to Computershare Trust Company, N.A. ("CTCNA") and its affiliates. For certain transactions where one or more of Wells Fargo's roles did not transfer to CTCNA on November 1, 2021, Wells Fargo engaged CTCNA as its agent to perform certain duties under the related transaction documents. Therefore, the reports on assessment of compliance with the servicing criteria for asset-backed securities and the related attestation reports on such assessments of compliance of CTCNA, as agent to Wells Fargo in its capacities as master servicer and custodian are included under Item 15.

Also, Christiana Trust, a division of Wilmington Savings Fund Society FSB (“Christiana”), the trustee, does not participate in any servicing function for the transaction that is the subject of this 10-K filing. Therefore, there is no reference to Christiana in the chart below; nor does this 10-K filing include any assessment or auditor report from Christiana. Finally, any discrepancies between the chart below and the assessment of compliance exhibit provided by any party listed in the chart is explained by the fact that the chart is specific to the transaction that is the subject of this 10-K filing, whereas each party’s respective assessment of compliance is issued on a platform basis and includes coverage of other additional transactions that are not the subject of this 10-K filing.
