The registrant knows of no material pending legal proceedinginvolving the trust or any party related to the trust, other than routine litigationincidental to the duties of those respective parties, and the following, withrespect to Wells Fargo Bank, National Association, as trustee, as certificateadministrator and as 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 as trusteefor certain residential mortgage backed securities (“RMBS”) trusts.  Thecomplaints against Wells Fargo Bank alleged that the trustee caused losses toinvestors and asserted causes of action based upon, among other things, thetrustee's alleged failure to: (i) notify and enforce repurchase obligations ofmortgage loan sellers for purported breaches of representations and warranties,(ii) notify investors of alleged events of default, and (iii) abide byappropriate standards of care following alleged events of default. Reliefsought included money damages in an unspecified amount, reimbursement ofexpenses, and equitable relief. Wells Fargo Bank has reached an agreement, inwhich it denies any wrongdoing, to resolve these claims on a classwide basisfor the 271 RMBS trusts currently at issue.  The settlement agreement issubject to court approval.  Separate lawsuits against Wells Fargo Bankmaking similar allegations filed by certain other institutional investorsconcerning 57 RMBS trusts in New York federal and state court are not coveredby the agreement.  With respect to the foregoing litigations, Wells FargoBank believes plaintiffs' claims are without merit and intends to contest theclaims vigorously, but there can be no assurances as to the outcome of thelitigations or the possible impact of the litigations on Wells Fargo Bank orthe RMBS trusts.

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, quality controlchecks and analysis.

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