The registrant knows of no material pending legal proceeding involving the trust or any party related to the trust, other than routine litigation incidental to the duties of those respective parties, and the following, with respect to Wells Fargo Bank, National Association, as trustee, certificate administrator and custodian, and KeyBank National Association, as primary servicer:

On June 18, 2014, a group of institutional investors filed a civil 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 trustee under 276 residential mortgage backed securities (“RMBS”) trusts, which was later amended on July 18, 2014, to increase the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a putative class action complaint in the United States District Court for the Southern District of New York (the “District Court”) against Wells Fargo Bank, alleging claims against the bank in its capacity as trustee for 274 RMBS trusts (the “Federal Court Complaint”). In December 2014, the plaintiffs’ motion to voluntarily dismiss their original state court action was granted. As with the prior state court action, the Federal Court Complaint is one of six similar complaints filed contemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of institutional investor plaintiffs. The Federal Court Complaint against Wells Fargo Bank alleges that the trustee caused losses to investors and asserts causes of action based upon, among other things, the trustee's alleged failure to: (i) 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 includes money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Other cases alleging similar causes of action have been filed against Wells Fargo Bank and other trustees in the District Court by RMBS investors in these and other transactions, and these cases against Wells Fargo Bank are proceeding before the same District Court judge. A similar complaint was also filed May 27, 2016 in New York state court by a different plaintiff investor. On January 19, 2016, an order was entered in connection with the Federal Court Complaint in which the District Court declined to exercise jurisdiction over 261 trusts at issue in the Federal Court Complaint; the District Court also allowed plaintiffs to file amended complaints as to the remaining, non-dismissed trusts, if they so chose, and three amended complaints have been filed. On December 17, 2016, the investor plaintiffs in the 261 trusts dismissed from the Federal Court Complaint filed a new complaint in New York state court (the “State Court Complaint”). In September 2017, Royal Park Investments SA/NV (“Royal Park”), one of the plaintiffs in the District Court cases against Wells Fargo Bank, filed a putative class action complaint relating to two trusts seeking declaratory and injunctive relief and money damages based on Wells Fargo Bank’s indemnification from trust funds for legal fees and expenses Wells Fargo Bank incurs or has incurred in defending the District Court case filed by Royal Park. With respect to the foregoing 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 outcome of the litigations or the possible impact of the litigations on Wells Fargo Bank or the RMBS trusts.

On February 23, 2016, a certificateholder of the J.P. Morgan Chase Commercial Mortgage Securities Trust, Series 2007-CIBC18 (the “Trust”) filed suit in the Supreme Court of New York, County of New York, against KeyBank National Association and Berkadia Commercial Mortgage LLC (collectively, the “Servicers”).  The suit was filed derivatively on behalf of the Trust.  The action was brought in connection with the Servicers’ determination of the fair value of a loan, secured by the Bryant Park Hotel in New York City, held by the Trust and sold to an assignee of the Trust’s directing certificateholder, pursuant to an exercise of the fair value option 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 possible impact of the litigation on the Servicers.  Both Servicers deny liability, believe that they performed their obligations in accordance with the terms of the Pooling and Servicing Agreement, and have contested the claims asserted against them, filing a motion to dismiss the case.  On November 28, 2016, the Servicers’ motion to dismiss was granted.  The plaintiff certificateholder has filed a notice of appeal, and the appeal is pending.
