**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 the following,with respect to Wells Fargo Bank, National Association, as trustee, certificateadministrator and custodian and U.S. Bank National Association, as trustee,certificate administrator and custodian:

Since June 18, 2014, a group of institutional investors havefiled civil complaints in the Supreme Court of the State of New York, New YorkCounty, and later the U.S. District Court for the Southern District of New Yorkagainst Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in its capacity astrustee for certain residential mortgage backed securities (“RMBS”)trusts.  The complaints against Wells Fargo Bank alleged that the trusteecaused losses to investors and asserted causes of action based upon, amongother things, the trustee’s alleged failure to: (i) notify and enforcerepurchase obligations of mortgage loan sellers for purported breaches ofrepresentations and warranties, (ii) notify investors of alleged events ofdefault, and (iii) abide by appropriate standards of care following allegedevents of default. Relief sought included money damages in an unspecifiedamount, reimbursement of expenses, and equitable relief. Wells Fargo Bank hasreached an agreement, in which it denies any wrongdoing, to resolve theseclaims on a classwide basis for the 271 RMBS trusts currently at issue. The settlement agreement is subject to court approval.  Separate lawsuitsagainst Wells Fargo Bank making similar allegations filed by certain otherinstitutional investors concerning 57 RMBS trusts in New York federal and statecourt are not covered by the agreement.  With respect to the foregoinglitigations, Wells Fargo Bank believes plaintiffs’ claims are without merit andintends to contest the claims vigorously, but there can be no assurances as tothe outcome of the litigations or the possible impact of the litigations onWells Fargo Bank or the RMBS trusts.

Since 2014 various plaintiffs or groups of plaintiffs,primarily investors, have filed claims against U.S. Bank National Association(“U.S. Bank”), in its capacity as trustee or successor trustee (as thecase may be) under certain residential mortgage backed securities (“RMBS”)trusts.  The plaintiffs or plaintiff groups have filed substantiallysimilar complaints against other RMBS trustees, including Deutsche Bank, Citibank,HSBC, Bank of New York Mellon and Wells Fargo.  The complaints againstU.S. Bank allege the trustee caused losses to investors as a result of allegedfailures by the sponsors, mortgage loan sellers and servicers for these RMBStrusts and assert causes of action based upon the trustee’s purported failureto enforce repurchase obligations of mortgage loan sellers for alleged breachesof representations and warranties concerning loan quality.  The complaintsalso assert that the trustee failed to notify securityholders of purportedevents of default allegedly caused by breaches of servicing standards bymortgage loan servicers and that the trustee purportedly failed to abide by aheightened standard of care following alleged events of default.  

Currently U.S. Bank is a defendant in multiple actionsalleging individual or class action claims against the trustee with respect tomultiple trusts as described above.  Previously, U.S. Bank disclosed thatthe most substantial case was:  BlackRock Balanced Capital Portfolio et alv. U.S. Bank National Association, No. 605204/2015 (N.Y. Sup. Ct.) (classaction alleging claims with respect to approximately 770 trusts) and itscompanion case BlackRock Core Bond Portfolio et al v. U.S. Bank NationalAssociation, No. 14-cv-9401 (S.D.N.Y.) (collectively, the “BlackRock cases”).U.S. Bank has entered into a settlement agreement that will resolve theBlackRock cases following approval of the dismissals by the applicablecourt.  Some of the trusts implicated in the aforementioned Blackrockcases, as well as other trusts, are involved in actions brought by separategroups of plaintiffs related to no more than 100 trusts per case.

U.S. Bank cannot assure you as to the outcome of any of thelitigation, or the possible impact of these litigations on the trustee or theRMBS trusts. However, U.S. Bank denies liability and believes that it hasperformed its obligations under the RMBS trusts in. good faith, that itsactions were not the cause of losses to investors and that it has meritoriousdefenses, and it intends to contest the plaintiffs’ claims vigorously.

Material Instance of Noncompliance

In certain instances, the ScheduleAL Files (Item 1125 of Regulation AB) were not reported in accordance with theterms specified in the transaction agreements, in conflict with Item1122(d)(3)(i): “Reports to investors, including those to be filed with theCommission, are maintained in accordance with the transaction agreements andapplicable Commission requirements. Specifically, such reports: (A) Areprepared in accordance with timeframes and other terms set forth in thetransaction agreements”.  The noncompliance consisted of omitted orinaccurately reported numbers due to the following: (1) the initial setup filescontained information at the asset level, and Midland was required to manuallycompile the information to present it at the loan level as required by ScheduleAL; and (2) certain reporting requirements required manual processing byMidland, including the use of various data computation formulas, qualitycontrol checks and analysis.

The identified instances did notinvolve the servicing of assets included in this securitization.

Steps Taken to Remedy the Material Instance of Noncompliance

Midland is currently remediating theSchedule AL reporting for the CMBS transactions found to be incorrect, and willbe making improvements to its systems, processes and procedures to support itsSchedule AL reporting obligations.
