This report may not be suitable for any other purpose. The procedures performed may not address all of the items of interest to a user of the report and may not meet the needs of all users of the report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes. The appropriateness of these procedures is solely the responsibility of the Specified Parties identified in this report. No other party acknowledged the appropriateness of the procedures. Consequently, we make no representation regarding the appropriateness of the procedures described in Attachment A, either for the purpose for which this report has been requested or for any other purpose.

 

The procedures performed and our associated findings are included in Attachment A.

 ii.Labeled “MSRM 2026-NQM5&6 EY Tape_2026-05-1.xlsx” and the corresponding record layout and decode information, as applicable (the “Preliminary Data File”), that the Initial Purchaser, on behalf of the Depositor, indicated contains information as of 1 May 2026 (the “Cut-off Date”) relating to the Preliminary Mortgage Loans,

For the purpose of the procedures described in this report, certain information on the Preliminary Data File is the “Subject Matter” as of the date of this report.

 

The procedures included in Attachment A were limited to comparing or recalculating certain information that is further described in Attachment A. The Depositor is responsible for the Subject Matter, Provided Data Files, Source Documents, Sample Characteristics and the determination of the instructions, assumptions and methodologies that are described herein. We were not requested to perform, and we have not performed, any procedures other than those listed in Attachment A. We have not verified, and we make no representation as to, the accuracy, completeness or reasonableness of the Loan Listing Data File, Source Documents or any other information provided to us, or that we were instructed to obtain, as applicable, by the Initial Purchaser, on behalf of the Depositor, upon which we relied in forming our findings. Accordingly, we make no representation and express no opinion or conclusion as to (a) the existence of the Preliminary Mortgage Loans or Mortgage Loans, (b) questions of legal or tax interpretation or (c) the appropriateness, accuracy, completeness or reasonableness of any instructions, assumptions and methodologies provided to us by the Initial Purchaser, on behalf of the Depositor, that are described in this report.

This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants (the “AICPA”). An agreed-upon procedures engagement involves the practitioner performing specific procedures that the Specified Parties have agreed to and acknowledged to be appropriate for the purpose of the engagement and reporting on findings based on the procedures performed. We were not engaged to, and did not, conduct an examination to express an opinion or a review to express a conclusion in accordance with attestation standards established by the AICPA on any of the items referred to herein. 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.

 

The agreed-upon procedures described in this report were not performed for the purpose of:

 a.Satisfying any criteria for due diligence published by a nationally recognized statistical rating organization (a “rating agency”) or

 ii.The value of the collateral securing the Mortgage Loans,
 iii.Whether the originator(s) of the Mortgage Loans complied with federal, state or local laws or regulations or
 iv.Any other factor or characteristic of the Mortgage Loans that would be material to the likelihood that the issuer of the Certificates will pay interest and principal in accordance with applicable terms and conditions.

 

We are required to be independent of the Depositor and to meet our other ethical responsibilities, as applicable, for agreed-upon procedures engagements set forth in the Preface: Applicable to All Members and Part 1 – Members in Public Practice of the Code of Professional Conduct established by the AICPA. Independence requirements for agreed-upon procedures engagements are less restrictive than independence requirements for audit and other attestation services.

 

This report is intended solely for the information and use of the Specified Parties and is not intended to be, and should not be, used by anyone other than the Specified Parties. It is not intended to be, and should not be, used by any other person or entity, including investors and rating agencies, who are not identified in the report as Specified Parties but who may have access to this report as required by law or regulation.

Procedures performed and our associated findings

 

 1.As instructed by the Initial Purchaser, on behalf of the Depositor, we randomly selected a sample of 420 Preliminary Mortgage Loans from the Loan Listing Data File (the “Base Sample Mortgage Loans”). For the purpose of this procedure, the Initial Purchaser, on behalf of the Depositor, did not inform us as to the basis for how they determined the number of Base Sample Mortgage Loans or the methodology they instructed us to use to select the Base Sample Mortgage Loans from the Loan Listing Data File.

 

For the purpose of the procedures described in this report, the 420 Base Sample Mortgage Loans are referred to as Sample Mortgage Loan Numbers 1 through 420.

 

 2.For each mortgage loan on the Loan Listing Data File and Preliminary Data File, we compared the Investor Loan ID, as shown on the Loan Listing Data File, to the corresponding Loan Number, as shown on the Preliminary Data File, and noted that:
 a.All of the Preliminary Mortgage Loans were included on both the Preliminary Data File and Loan Listing Data File and
 b.No mortgage loans other than the Preliminary Mortgage Loans were included on the Loan Listing Data File or Preliminary Data File.

 

 3.As instructed by the Initial Purchaser, on behalf of the Depositor, we identified 238 Base Sample Mortgage Loans on the Preliminary Data File (the “Sample Mortgage Loans”) that have a deal name of “NQM5,” as shown on the Loan Listing Data File.

 

 4.For each Sample Mortgage Loan, we compared the Sample Characteristics listed on Exhibit 1 to Attachment A, as shown on the Preliminary Data File, to the corresponding information located in, or to the corresponding information we recalculated using information located in, the Source Documents or Preliminary Data File, as applicable, subject to the instructions, assumptions and methodologies provided by the Initial Purchaser, on behalf of the Depositor, described in the notes to Exhibit 1 to Attachment A. The Source Document(s) that we were instructed by the Initial Purchaser, on behalf of the Depositor, to use for each Sample Characteristic are shown on Exhibit 1 to Attachment A. Except for the information shown on Exhibit 2 to Attachment A, all such compared information was found to be in agreement.
