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, KeyBank National Association, as primary servicerand U.S. Bank National Association, as trustee, certificate administrator andcustodian:

On June 18, 2014, a group of institutional investors filed acivil complaint in the Supreme Court of the State of New York, New York County,against Wells Fargo Bank, N.A. (“Wells Fargo Bank”) in its capacity as trusteeunder 276 residential mortgage backed securities (“RMBS”) trusts, which waslater amended on July 18, 2014, to increase the number of trusts to 284 RMBStrusts. On November 24, 2014, the plaintiffs filed a motion to voluntarilydismiss the state court action without prejudice. That same day, a group ofinstitutional investors filed a putative class action complaint in the UnitedStates District Court for the Southern District of New York (the “DistrictCourt”) against Wells Fargo Bank, alleging claims against the bank in itscapacity as trustee for 274 RMBS trusts (the “Federal Court Complaint”). InDecember 2014, the plaintiffs’ motion to voluntarily dismiss their originalstate court action was granted. As with the prior state court action, theFederal Court Complaint is one of six similar complaints filedcontemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank ofNew York Mellon and US Bank) by a group of institutional investor plaintiffs.The Federal Court Complaint against Wells Fargo Bank alleges that the trustee causedlosses to investors and asserts causes of action based upon, among otherthings, the trustee's alleged failure to: (i) notify and enforce repurchaseobligations of mortgage loan sellers for purported breaches of representationsand warranties, (ii) notify investors of alleged events of default, and (iii)abide by appropriate standards of care following alleged events of default.Relief sought includes money damages in an unspecified amount, reimbursement ofexpenses, and equitable relief. Other cases alleging similar causes of actionhave been filed against Wells Fargo Bank and other trustees in the DistrictCourt by RMBS investors in these and other transactions, and these casesagainst Wells Fargo Bank are proceeding before the same District Court judge. Asimilar complaint was also filed May 27, 2016 in New York state court by adifferent plaintiff investor. On January 19, 2016, an order was entered inconnection with the Federal Court Complaint in which the District Courtdeclined to exercise jurisdiction over 261 trusts at issue in the Federal CourtComplaint; the District Court also allowed plaintiffs to file amendedcomplaints as to the remaining, non-dismissed trusts, if they so chose, andthree amended complaints have been filed. On December 17, 2016, the investorplaintiffs in the 261 trusts dismissed from the Federal Court Complaint filed anew complaint in New York state court (the “State Court Complaint”). InSeptember 2017, Royal Park Investments SA/NV (“Royal Park”), one of theplaintiffs in the District Court cases against Wells Fargo Bank, filed aputative class action complaint relating to two trusts seeking declaratory andinjunctive relief and money damages based on Wells Fargo Bank’s indemnificationfrom trust funds for legal fees and expenses Wells Fargo Bank incurs or hasincurred in defending the District Court case filed by Royal Park. With respectto the foregoing litigations, Wells Fargo Bank believes plaintiffs' claims arewithout merit and intends to contest the claims vigorously, but there can be noassurances as to the outcome of the litigations or the possible impact of thelitigations on Wells Fargo Bank or the RMBS trusts.

On February 23, 2016, acertificateholder of the J.P. Morgan Chase Commercial Mortgage SecuritiesTrust, Series 2007-CIBC18 (the “Trust”) filed suit in the Supreme Court of NewYork, County of New York, against KeyBank National Association and BerkadiaCommercial Mortgage LLC (collectively, the “Servicers”). The suit was filedderivatively on behalf of the Trust. The action was brought in connection withthe Servicers’ determination of the fair value of a loan, secured by the BryantPark Hotel in New York City, held by the Trust and sold to an assignee of theTrust’s directing certificateholder, pursuant to an exercise of the fair valueoption set forth in the Pooling and Servicing Agreement governing the Trust.There can be no assurances as to the outcome of the action or the possibleimpact of the litigation on the Servicers. Both Servicers deny liability, believethat they performed their obligations in accordance with the terms of thePooling and Servicing Agreement, and have contested the claims asserted againstthem, filing a motion to dismiss the case. On November 28, 2016, the Servicers’motion to dismiss was granted. The plaintiff certificateholder has filed anotice of appeal, and the appeal is pending.

Since 2014 various plaintiffs orgroups of plaintiffs, primarily investors, have filed claims against U.S. BankNational Association (“U.S. Bank”), in its capacity as trustee or successortrustee (as the case may be) under certain residential mortgage-backedsecurities (“RMBS”) trusts. The plaintiffs or plaintiff groups have filedsubstantially similar complaints against other RMBS trustees, including DeutscheBank, Citibank, HSBC, Bank of New York Mellon and Wells Fargo. The complaintsagainst U.S. Bank allege the trustee caused losses to investors as a result ofalleged failures by the sponsors, mortgage loan sellers and servicers for theseRMBS trusts and assert causes of action based upon the trustee's purportedfailure to enforce repurchase obligations of mortgage loan sellers for allegedbreaches of representations and warranties concerning loan quality. Thecomplaints also assert that the trustee failed to notify securityholders ofpurported events of default allegedly caused by breaches of servicing standardsby mortgage loan servicers and that the trustee purportedly failed to abide bya heightened standard of care following alleged events of default.

Currently U.S. Bank is a defendantin multiple actions alleging individual or class action claims against thetrustee with respect to multiple trusts as described above with the mostsubstantial case being: *BlackRock Balanced Capital Portfolio**et al v.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.). Some of the trusts implicated inthe aforementioned Blackrock cases, as well as other trusts, are involved inactions brought by separate groups of plaintiffs related to no more than 100trusts 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 its actionswere not the cause of losses to investors and that it has meritorious defenses,and it intends to contest the plaintiffs’ claims vigorously.
