**Item 1117 of Regulation AB, Legal Proceedings.**

The registrant knows of no material pending legal proceedinginvolving the trust or any party related to the trust, other than routinelitigation incidental to the duties of those respective parties, and thefollowing, with respect to CWCapital Asset Management LLC, as special servicer,and Wells Fargo Bank, National Association, as trustee, certificateadministrator and custodian. 

From time totime, CWCapital Asset Management LLC, a Delaware limited liability company(“CWCAM”), is a party to lawsuits and other legal proceedings as part of itsduties as a special servicer (e.g., enforcement of loan obligations) and/orarising in the ordinary course of business. Other than as set forth in thefollowing paragraphs, there are currently no legal proceedings pending, and nolegal proceedings known to be contemplated by governmental authorities, againstCWCAM or of which any of its property is the subject, that are material to thecertificateholders. 

On December 17,2015, U.S. Bank National Association, the trustee under five pooling andservicing agreements for (i) Wachovia Bank Commercial Mortgage Trust 2007-C30,(ii) COBALT CMBS Commercial Trust 2007-C2, (iii) Wachovia Bank CommercialMortgage Trust 2007-C31, (iv) ML-CFC Commercial Mortgage Trust 2007-5 and (v)ML-CFC Commercial Mortgage Trust 2007-6 commenced a proceeding with the SecondJudicial District Court of Ramsey County, Minnesota (the “State Court”) for adeclaratory judgment as to the proper allocation of certain proceeds (“DisputedProceeds”) received by CWCAM in connection with the sale of the Peter CooperVillage and Stuyvesant Town property in New York, New York securing loans heldby those trusts.  CWCAM was the special servicer of such property. The petition requests the State Court to instruct the trustee, the trustbeneficiaries, and any other interested parties as to the amount of theDisputed Proceeds, if any, that constitute penalty interest and/or the amountof the Disputed Proceeds, if any, that constitute gain-on-sale proceeds, withrespect to each trust.  On February 24, 2016, CWCAM made a limitedappearance with the State Court to file a motion to dismiss this proceedingbased on lack of jurisdiction, mootness, standing and forum nonconveniens.  On July 19, 2016, the State Court denied CWCAM’s motion todismiss.  On July 22, 2016, the action was removed to federal court inMinnesota (“Federal Court”).  On October 21, 2016, the Federal Court helda hearing on the motion to transfer the action to the United States DistrictCourt for the Southern District of New York (“SDNY Court”), a motion to remandto state court and a motion to hear CWCAM’s request for reconsideration of themotion to dismiss.  On March 14, 2017, the Federal Court reserved thedetermination on the motion to hear CWCAM’s request for reconsideration of themotion to dismiss, denied the motion to remand the matter to state court andgranted the motion to transfer the proceeding to the SDNY Court.  Crossmotions for judgment on the pleadings were filed but the SDNY Court was unableto decide the case based on the pleadings and the SDNY Court ordereddiscovery.  All fact discovery was completed in December, 2018 and expert discoverywas completed on March 15, 2019.  The parties submitted cross motions forsummary judgment, and on March 19, 2020, the SDNY Court entered an opinion andorder in which it granted summary judgment in CWCAM’s favor and held that CWCAMwas entitled to the entire amount of penalty interest and that CWCAM’sdetermination of Yield Maintenance was correct.  In the 127-page opinion,the SDNY Court found for CWCAM on every issue presented by the trustee’spetition, namely, that the funds in dispute constitute penalty interest andyield maintenance, not gain-on-sale proceeds, and that the amount of penaltyinterest and yield maintenance was correctly calculated. An appeal of the SDNYCourt’s decision was taken on April 29, 2020.  Oral argument on the appealoccurred on June 21, 2021.  On July 14, 2022, the Second Circuit entered adecision affirming in part and reversing in part the SDNY Court’s decision andremanding to the SDNY Court for further proceedings.  The Second Circuitaffirmed the SDNY’s Court holding that Penalty Interest and Yield Maintenanceare paid before Gain-On-Sale Proceeds.  The Second Circuit reversed andremanded for further proceedings that portion of the SDNY Court’s decisionrelated to approximately $67.2 million in interest on advances.   OnJanuary 13, 2023, the parties entered into a settlement agreement, in which(among other things) they agreed to stipulate that the amount of interest onadvances that accrued on or before June 3, 2014 is $27.5 million, and thatCWCAM would pay that amount into escrow for distribution to certificateholdersupon the entry of an order by the Court approving the settlement.  U.S.Bank National Association, as Trustee for the trusts, provided notice of thesettlement to all parties in interest via a notice program approved by theCourt.  A hearing on the settlement is scheduled for March 16, 2023.

On December 1,2017, a complaint against CWCAM and others was filed in the United StatesDistrict Court for the Southern District of New York styled as CWCapital CobaltVr Ltd. v. CWCapital Investments LLC, et al., No. 17-cv-9463 (the “OriginalComplaint”). The gravamen of the Original  Complaint alleged breaches of acontract and fiduciary duties by CWCAM’s affiliate, CWCapital Investments LLCin its capacity as collateral manager for the collateralized debt obligationtransaction involving CWCapital Cobalt Vr, Ltd. In total, there are 14 countspled in the Original Complaint. Of those 14, 5 claims were asserted againstCWCAM for aiding and abetting breach of fiduciary duty, conversion and unjustenrichment. On May 23, 2018, the Original Complaint was dismissed for lack ofsubject matter jurisdiction.   On June 28, 2018, CWCapital Cobalt VrLtd. filed a substantially similar complaint in the Supreme Court of the Stateof New York, County of New York styled as CWCapital Cobalt Vr Ltd. v. CWCapitalInvestments LLC, et al., Index No. 653277/2018 (the “New Complaint”).  Thegravamen of the New Complaint is thesameas the previous complaint filed in the United State District Court for theSouthern District of New York.  In total there are 16 counts pled in theNew Complaint. Of those 16 counts, 5 claims were asserted against CWCAM foraiding and abetting breach of fiduciary duty, conversion and unjust enrichment,1 count seeks a declaratory judgement that the plaintiff has the right toenforce the contracts in question and 1 count seeks an injunction requiring thedefendants to recognize the plaintiff as the directing holder for the trusts inquestion. On January 11, 2019, the plaintiff dismissed with prejudice thedeclaratory judgment and injunction counts.  The New Complaint and relatedsummons was not served on the defendants until July 13, 2018 and July 16,2018.  The plaintiff’s motion for a preliminary injunction was denied bythe court on July 31, 2018.  On August 3, 2018, the defendants, includingCWCAM, filed a motion to dismiss the New Complaint in its entirety. On August20, 2019, the court entered an order granting defendants’ motion almost in itsentirety, dismissing 11 of the 16 counts and partially dismissing 2 additionalcounts.  Of the remaining counts, 2 are asserted against CWCAM for aidingand abetting breach of fiduciary duty and unjust enrichment.  On September19, 2019, CWCapital Cobalt Vr Ltd. filed a notice of appeal relating to theAugust 20, 2019 dismissal order and on September 26, 2019, filed an amendedcomplaint against CWCI and CWCAM attempting to address deficiencies relating tocertain of the claims dismissed by the August 20, 2019 order.  CWCI andCWCAM filed its Motion to Dismiss the amended complaint on October 28,2019.  The court heard argument on the Motion to Dismiss the amendedcomplaint on January 22, 2020 and on October 23, 2020, the court granted themotion dismissing the amended claims.  On November 30, 2020, CWCapitalCobalt Vr Ltd filed a notice of appeal relating to the October 23, 2020dismissal order.  On April 27, 2021, the First Department affirmed thedismissal as to claims against CWCAM that were part of the August 20, 2019 dismissal,but reversed the dismissal of two counts for breach of the CollateralManagement Agreement against CWCI.  CWCI sought leave to file an appeal ofthe decision. The plaintiff also sought leave to appeal the dismissal of theclaims against CWCAM.  Both requests for leave were denied by the FirstDepartment.  On May 15, 2020, CWCI and CWCAM filed a motion to renew itsmotion to dismiss as to 4 of the remaining counts (including the remaining twocounts against CWCAM for aiding and abetting breach of fiduciary duty andunjust enrichment), based on a decision entered by Judge Failla in a trustinstruction proceeding  in the US District Court for the Southern Districtof New York awarding summary judgment in favor of CWCAM.  On September 7,2021, the court denied the motion to renew.  CWCI and CWCAM filed a noticeof appeal, which they perfected by the filing of their opening brief on July 1,2022.  On November 15, 2022, the First Department affirmed the court’sdenial of the motion to renew.  On October 1, 2021, CWCI and CWCAM movedto reargue the denial of the motion to renew (or alternatively, the motion todismiss) with respect to certain of Cobalt’s claims, including the remaining 2claims against CWCAM, based on the First Department’s April 27, 2021 decision. On March 24, 2022, the court denied the relief sought in the motion toreargue.  CWCI and CWCAM have appealed the court’s decision on the motionto reargue and filed their opening brief on July 11, 2022.  The appeal wasdismissed as being non-appealable on August 30, 2022.  CWCAM believes thatit has performed its obligations under the related pooling and servicingagreements in good faith and the remaining allegations in the New Complaint arewithout merit.   

In December2014, Phoenix Light SF Limited (Phoenix Light) and certain related entitiesfiled a complaint in the United States District Court for the Southern Districtof New York alleging claims against Wells Fargo Bank, N.A., in its capacity astrustee for a number of residential mortgage-backed securities (RMBS) trusts.Complaints raising similar allegations have been filed by Commerzbank AG in theSouthern District of New York and by IKB International and IKB DeutscheIndustriebank in New York state court. In each case, the plaintiffs allege thatWells Fargo Bank, N.A., as trustee, caused losses to investors, and plaintiffsassert causes of action based upon, among other things, the trustee’s allegedfailure to notify and enforce repurchase obligations of mortgage loan sellersfor purported breaches of representations and warranties, notify investors ofalleged events of default, and abide by appropriate standards of care followingalleged events of default. In July 2022, the district court dismissed PhoenixLight’s claims and certain of the claims asserted by Commerzbank AG, andsubsequently entered judgment in each case in favor of Wells Fargo Bank, N.A.In August 2022, Phoenix Light and Commerzbank AG appealed the district court’sdecision to the United States Court of Appeals for the Second Circuit. TheCompany previously settled two class actions filed by institutional investorsand an action filed by the National Credit Union Administration with similarallegations. In addition, Park Royal I LLC and Park Royal II LLC have filedsubstantially similar lawsuits in New York state court alleging Wells FargoBank, N.A., as trustee, failed to take appropriate actions upon learning ofdefective mortgage loan documentation.

The examinationperformed by Ernst & Young LLP identified an instance of materialnoncompliance with the servicing criteria set forth in Item 1122(d)(4)(ix) ofRegulation AB applicable to KeyBank during the year ended December 31, 2022.During compliance testing, it was discovered,that not all FlexARM loan mortgagors were offered loan rates within 45-60 daysbefore the rate change date, as required per the related pool asset documents.Per the related note, if the holder fails to offer a loan rate within 45-60days of any change date a margin of 2.25% is to be used. Given the notificationwas not made to the borrowers, a 3% margin was incorrectly applied. Thenoncompliance in Item 1122 (d)(4)(ix) is related to a servicing portfolio whichis wholly owned by the investor and is not held in a publicly traded security.

The followingremediation procedures have been initiated by KeyBank: (i) the impactedmortgage loans are currently in the process of being identified, (ii) investorcontact has been initiated, (iii) corrective actions are being considered andwill be tracked and monitored by senior management, (iv) procedures will bereviewed and revised, if necessary, to include new tracking and action steps toprevent this situation from recurring in the future, and (v) training will beprovided to the relevant staff members to prevent a recurrence.
