In an agreed-upon procedures engagement, we perform specific procedures that the Specified Parties have agreed to and acknowledged to be appropriate for the intended purpose of the engagement and we report on findings based on the procedures performed.

The Specified Parties have agreed to and acknowledged that the procedures performed are appropriate for their purposes. This report may not be suitable for any other purpose.
Procedures and Findings
In connection with the Transaction, the Specified Parties have requested that the procedures be performed on the entire population of collateral for the Transaction, consisting of 44 mortgage loans (the “Mortgage Loan Assets”) secured by 44 mortgaged properties (the “Mortgaged Properties”) (collectively the “Collateral”) within the Transaction.
This agreed-upon procedures engagement was not conducted for the purpose of satisfying any criteria for due diligence published by a nationally recognized statistical rating organization.

| · | the value of collateral securing such assets; and |
| · | the compliance of the originator of the assets with federal, state, and local laws and regulations. |
We have not performed any procedures with respect to the fair value of the securities being offered in the Transaction and PwC expresses no opinion on the current fair value of these securities. PwC should not be regarded as having performed any procedures other than those detailed in this report.
With respect to any terms or requirements of the Transaction documents that do not appear in this report, we performed no procedures and, accordingly, the procedures we performed would not ensure that any requirements are satisfied.

| · | your compliance with Rule 15Ga-2 of the Securities Exchange Act of 1934; and |

received one or more preliminary data file(s) and performed certain procedures as set forth in Exhibit A, Exhibit B and Exhibit C.

From June 11, 2026 through July 13, 2026, the Company provided us with the Source Documents related to the Collateral for which:
| ● | We compared certain Specified Attributes to the corresponding Source Documents as detailed in Exhibit A and found them to be in agreement (the “Compared Attributes”); |

| ● | Certain Specified Attributes were provided by the Company and were not compared to the corresponding Source Documents. These attributes are listed in Exhibit A as a “Company Provided Attribute” and in Exhibit C. |
| ● | Applied Methodologies to certain Specified Attributes, as detailed in Exhibit C. |
The recalculation methodology associated with the Recalculated Attributes is listed in Exhibit B. For each procedure where a recalculation was performed, if necessary, we compared the underlying attributes to the corresponding Source Documents and found them to be in agreement.
This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. We were not engaged to, and did not conduct an audit or an examination engagement, the objective of which would be the expression of an opinion, or a review engagement, the objective of which would be the expression of a conclusion, on the Transaction or the Final Data File. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.
