This is a supplement ("<u>Supplement</u>") to the prospectus dated May 18, 2026 (the "<u>Preliminary Prospectus</u>"). Capitalized terms used in this supplement but not defined herein have the meanings given to them in the Preliminary Prospectus.

**<u>Structural Updates</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Class A-S Certificates</u>. The structure of the transaction is being updated to add the Class A-S certificates and the related classes of Exchangeable Certificates (Class A-S-1, Class A-S-2, Class A-S-X1 and Class A-S-X2 certificates), which classes of certificates are being offered by the Preliminary Prospectus, as supplemented by this Supplement. The approximate initial certificate balance of the Class A-S certificates is $60,573,000. The Class A-S, Class A-S-1, Class A-S-2, Class A-S-X1 and Class A-S-X2 certificates are collectively referred to as the "<u>Class A-S Exchangeable Certificates</u>".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Expected Range of Initial Certificate Balance of Class A-3 Trust Component</u>. The expected range of initial certificate balances of the Class A-3 trust component is changing from $324,523,000 - $574,523,000 to $263,950,000 - $513,950,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Class X-A Notional Amount</u>. The approximate initial notional amount of the Class X-A certificates is being reduced from $574,523,000 to $513,950,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Class X-B Certificates</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The notional amount of the Class X-B certificates is changing from being equal to the aggregate certificate balances of the Class B and Class C trust components outstanding from time to time to being equal to the aggregate certificate balances of the Class A-S, Class B and Class C trust components outstanding from time to time. The approximate initial notional amount of the Class X-B certificates is being increased from $74,339,000 to $134,912,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The pass-through rate for the Class X-B certificates for any distribution date will be a *per annum* rate equal to the excess, if any, of (a) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, over (b) the weighted average of the pass-through rates on the Class A-S, Class A-S-X1, Class A-S-X2, Class B, Class B-X1, Class B-X2, Class C, Class C-X1 and Class C-X2 trust components for the related distribution date, weighted on the basis of their respective aggregate certificate balances or notional amounts outstanding immediately prior to that distribution date (but excluding trust components with a notional amount in the denominator of such weighted average calculation).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Class X-S Notional Amount</u>.

The notional amount of the Class X-S certificates will be equal to the aggregate certificate balance of the Class A-2, Class A-3, Class A-S, Class B and Class C trust components and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates outstanding from time to time. The approximate initial notional amount of the Class X-S certificates will be $734,215,000.

<sup>(1)</sup> Approximate, subject to a variance of plus or minus 5% and further subject to the discussion in footnote (6) below. In addition, the notional amounts of the Class X-A, Class X-B, Class X-D and Class X-F certificates (together with the Class X-S certificates, referred to herein as "<u>Class X certificates</u>") may vary depending upon the final pricing of the classes of principal balance certificates or trust components whose certificate balances comprise such notional amounts and, if as a result of such pricing the pass-through rate of any class of the Class X certificates would be equal to zero at all times, such class of certificates will not be issued on the closing date of this securitization.

<sup>(2)</sup> The approximate initial credit support percentages set forth for the certificates are approximate and, for the Class A-2 and Class A-3 certificates, are presented in the aggregate, taking into account the certificate balance of the Class A-2 and A-3 trust components. The approximate initial credit support percentages set forth for the Class A-S, Class B and Class C certificates represent the approximate credit support for the underlying Class A-S, Class B and Class C trust components, respectively.

<sup>(3)</sup> The assumed final distribution dates set forth in this prospectus have been determined on the basis of the assumptions described in "*Description of the Certificates*—*Assumed Final Distribution Date*; *Rated Final Distribution Date*".

<sup>(4)</sup> The weighted average life and expected principal window during which distributions of principal would be received as set forth in the foregoing table with respect to each class of certificates having a certificate balance are based on the assumptions set forth under "*Yield and Maturity Considerations*—*Weighted Average Life*" and on the assumptions that there are no prepayments, modifications or losses in respect of the mortgage loans and that there are no extensions or forbearances of maturity dates of the mortgage loans.

<sup>(5)</sup> The Class A-2-1, Class A-2-2, Class A-2-X1, Class A-2-X2, Class A-3-1, Class A-3-2, Class A-3-X1, Class A-3-X2, Class A-S-1, Class A-S-2, Class A-S-X1, Class A-S-X2, Class B-1, Class B-2, Class B-X1, Class B-X2, Class C-1, Class C-2, Class C-X1 and Class C-X2 certificates are also offered certificates. Such classes of certificates, together with the Class A-2, Class A-3, Class A-S, Class B and Class C certificates, constitute the "<u>Exchangeable Certificates</u>". The Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates, together with the Exchangeable Certificates with a certificate balance, are referred to as the "principal balance certificates." Each class of Exchangeable Certificates will have the certificate balance or notional amount and pass-through rate described under "*Description of the Certificates—Distributions—Exchangeable Certificates*."

<sup>(6)</sup> The exact initial certificate balances or notional amounts of the Class A-2, Class A-2-X1, Class A-2-X2, Class A-3, Class A-3-X1 and Class A-3-X2 trust components (and consequently, the exact initial certificate balance or notional amount of each class of Class A-2 Exchangeable Certificates and Class A-3 Exchangeable Certificates) are unknown and will be determined based on the final pricing of the certificates. However, the initial certificate balances, assumed final distribution dates, weighted average lives and principal windows of the Class A-2 and Class A-3 trust components are expected to be within the applicable ranges reflected in the following chart. The aggregate of the initial certificate balances of the Class A-2 and Class A-3 trust components is expected to be approximately $513,950,000, subject to a variance of plus or minus 5%. The Class A-2-X1 and Class A-2-X2 trust components will have initial notional amounts equal to the initial certificate balance of the Class A-2 trust component. The Class A-3-X1 and Class A-3-X2 trust components will have initial notional amounts equal to the initial certificate balance of the Class A-3 trust component. In the event that the Class A-3 trust component is issued with an initial certificate balance of $513,950,000, the Class A-2 trust component (and, correspondingly, the Class A-2 Exchangeable Certificates) will not be issued.

<sup>(7)</sup> The pass-through rate for each class of the Class A-2, Class A-3, Class A-S, Class B, Class C, Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates for any distribution date will be one of the following: (i) a fixed rate *per annum*, (ii) a variable rate *per annum* equal to the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, (iii) a variable rate *per annum* equal to the lesser of (a) a fixed rate and (b) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate or (iv) a variable rate *per annum* equal to the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date minus the Class X-S Excess Strip Rate and a specified percentage. For purposes of the calculation of the weighted average of the net mortgage interest rates on the mortgage loans for each distribution date, the mortgage interest rates will be adjusted as necessary to a 30/360 basis.

<sup>(8)</sup> The Class X-A certificates are notional amount certificates. The notional amount of the Class X-A certificates will be equal to the aggregate certificate balance of the Class A-2 and Class A-3 trust components outstanding from time to time. The Class X-A certificates will not be entitled to distributions of principal.

<sup>(9)</sup> The pass-through rate for the Class X-A certificates for any distribution date will be a *per annum* rate equal to the excess, if any, of (a) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, over (b) the weighted average of the pass-through rates on the Class A-2, Class A-2-X1, Class A-2-X2, Class A-3, Class A-3-X1 and Class A-3-X2 trust components for the related distribution date, weighted on the basis of their respective aggregate certificate balances or notional amounts outstanding immediately prior to that distribution date (but excluding trust components with a notional amount in the denominator of such weighted average calculation). For purposes of the calculation of the weighted average of the net mortgage interest rates on the mortgage loans for each distribution date, the mortgage interest rates will be adjusted as necessary to a 30/360 basis.

<sup>(10)</sup> The Class X-B certificates are notional amount certificates. The notional amount of the Class X-B certificates will be equal to the aggregate certificate balance of the Class A-S, Class B and Class C trust components outstanding from time to time. The Class X-B certificates will not be entitled to distributions of principal.

<sup>(11)</sup> The pass-through rate for the Class X-B certificates for any distribution date will be a *per annum* rate equal to the excess, if any, of (a) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, over (b) the weighted average of the pass-through rates on the Class A-S, Class A-S-X1, Class A-S-X2, Class B, Class B-X1, Class B-X2, Class C, Class C-X1 and Class C-X2 trust components for the related distribution date, weighted on the basis of their respective aggregate certificate balances or notional amounts outstanding immediately prior to that distribution date (but excluding trust components with a notional amount in the denominator of such weighted average calculation). For purposes of the calculation of the weighted average of the net mortgage interest rates on the mortgage loans for each distribution date, the mortgage interest rates will be adjusted as necessary to a 30/360 basis.

<sup>(12)</sup> The Class X-D, Class X-F and Class X-S certificates are notional amount certificates and will not be entitled to distributions of principal. The notional amount of the Class X-D certificates will be equal to the aggregate certificate balance of the Class D and Class E certificates outstanding from time to time. The notional amount of the Class X-F certificates will be equal to the certificate balance of the Class F certificates outstanding from time to time. The notional amount of the Class X-S certificates will be equal to the aggregate certificate balance of the Class A-2, Class A-3, Class A-S, Class B and Class C trust components and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates outstanding from time to time.

<sup>(13)</sup> The pass-through rate for the Class X-D certificates for any distribution date will be a *per annum* rate equal to the excess, if any, of (a) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, over (b) the weighted average of the pass-through rates on the Class D and Class E certificates for the related distribution date, weighted on the basis of their respective aggregate certificate balances outstanding immediately prior to that distribution date. The pass-through rate for the Class X-F certificates for any distribution date will be a *per annum* rate equal to the excess, if any, of (a) the weighted average of the net mortgage interest rates on the mortgage loans for the related distribution date *minus* the Class X-S Excess Strip Rate, over (b) the pass-through rates on the Class F certificates for the related distribution date. For purposes of the calculation of the weighted average of the net mortgage interest rates on the mortgage loans for each distribution date, the mortgage interest rates will be adjusted as necessary to a 30/360 basis. The pass-through rate for the Class X-S certificates for any distribution date will be a *per annum* rate equal to 0.10140% (the "<u>Class X-S Excess Strip Rate</u>").

<sup>(14)</sup> The notional amount of the Class X-F certificates and the initial certificate balance of each of the Class F and Class G-RR certificates are estimated based in part on the estimated ranges of certificate balances and estimated fair values described in "*Credit Risk Retention*". The initial certificate balance of the Class F certificates is expected to fall within a range of $7,342,000 and $10,096,000, and the initial certificate balance of the Class G-RR certificates is expected to fall within a range of $7,342,000 and $10,096,000, with the ultimate initial certificate balance of each determined such that the aggregate fair value of the Class G-RR, Class H-RR and Class J-RR certificates (collectively, the "<u>Horizontal Risk Retention Certificates</u>") will equal at least 5% of the estimated fair value as of the Closing Date of all of the classes of certificates (other than the Class R certificates) issued by the issuing entity. Any variation in the initial certificate balance of the Class F certificates would affect the initial notional amount of the Class X-F certificates.

<sup>(15)</sup> The Class R certificates will not have a certificate balance, notional amount, credit support, pass-through rate, assumed final distribution date, rated final distribution date or rating. The Class R certificates represent the residual interest in each Trust REMIC as further described in this prospectus. The Class R certificates will not be entitled to distributions of principal or interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.

<sup>(1)</sup> The range of assumed final distribution dates is based on the initial certificate balance of the Class A-2 trust component ranging from $0 to $250,000,000 and the initial certificate balance of the Class A-3 trust component ranging from $263,950,000 to $513,950,000.

<sup>(2)</sup> Each class of Class A-2 Exchangeable Certificates, Class A-3 Exchangeable Certificates, Class A-S Exchangeable Certificates, Class B Exchangeable Certificates and Class C Exchangeable Certificates that are principal balance certificates will have the same assumed final distribution date as the Class A-2, Class A-3, Class A-S, Class B or Class C certificates, respectively, shown in the table.

<sup>(1)</sup> The approximate initial credit support with respect to the Class A-2 and Class A-3 certificates are presented in the aggregate, taking into account the certificate balance of the Class A-2 and Class A-3 trust components. The approximate initial credit support set forth for the Class A-S certificates represents the approximate credit support for the Class A-S trust component. The approximate initial credit support set forth for the Class B certificates represents the approximate credit support for the Class B trust component. The approximate initial credit support set forth for the Class C certificates represents the approximate credit support for the Class C trust component.

<sup>(2)</sup> The exact initial certificate balances or notional amounts of the Class A-2, Class A-2-X1, Class A-2-X2, Class A-3, Class A-3-X1 and Class A-3-X2 trust components (and consequently, the exact initial certificate balance or notional amount of each class of Class A-2 Exchangeable Certificates and Class A-3 Exchangeable Certificates) are unknown and will be determined based on the final pricing of the certificates. However, the initial certificate balance of the Class A-2 trust component is expected to be within the range of $0 - $250,000,000 (0.000% - 34.050% of the Initial Pool Balance), and the initial certificate balance of the Class A-3 trust component is expected to be within the range of $263,950,000 - $513,950,000 (35.950% - 70.000% of the Initial Pool Balance). The aggregate initial certificate balance of the Class A-2 and Class A-3 trust components is expected to be approximately $513,950,000, subject to a variance of plus or minus 5%. The Class A-2-X1 and Class A-2-X2 trust components will have initial notional amounts equal to the initial certificate balance of the Class A-2 trust component. The Class A-3-X1 and Class A-3-X2 trust components will have initial notional amounts equal to the initial certificate balance of the Class A-3 trust component.

<sup>(3)</sup> Each class of Exchangeable Certificates will have the certificate balance or notional amount described under "*Description of the Certificates—Distributions—Exchangeable Certificates*".

*Thirty-first,* to the Class R certificates, any remaining amounts.

The "<u>Cross-Over Date</u>" means the Distribution Date on which the Certificate Balances of the Subordinate Certificates (other than the Class A-S Exchangeable Certificates, Class B Exchangeable Certificates and the Class C Exchangeable Certificates) and the Class A-S, Class B and Class C Trust Components have all previously been reduced to zero as a result of the allocation of Realized Losses to those certificates.

Reimbursement of previously allocated Realized Losses will not constitute distributions of principal for any purpose and will not result in an additional reduction in the

Certificate Balance of the class of certificates or Trust Component in respect of which a reimbursement is made.

Principal and interest payable on the Trust Components will be distributed *pro rata* to the corresponding classes of Exchangeable Certificates representing interests therein in accordance with their Class Percentage Interests therein as described below under "*—Exchangeable Certificates*".

If and to the extent that any Nonrecoverable Advances (plus interest on such Nonrecoverable Advances) that were reimbursed from principal collections on the Mortgage Loans (including REO Loans) and previously resulted in a reduction of the Principal Distribution Amount are subsequently recovered on the related Mortgage Loan or REO Property, then (on the Distribution Date related to the Collection Period during which the recovery occurred): (i) the amount of such recovery will be added to the Certificate Balance(s) of the class or classes of Principal Balance Certificates that previously were allocated Realized Losses, in the order of distributions set forth in "—*Priority of Distributions*" above, in each case up to the lesser of (A) the unallocated portion of such recovery and (B) the amount of the unreimbursed Realized Losses previously allocated to the subject class of certificates; and (ii) the Interest Shortfall with respect to each affected class of Certificates (other than the Class R certificates) or Trust Components for the next Distribution Date will be increased by the amount of interest that would have accrued through the then-current Distribution Date if the restored write-down for the reimbursed class of Principal Balance Certificates had never been written down. If the Certificate Balance of any class of Principal Balance Certificates is so increased, the amount of unreimbursed Realized Losses of such class of certificates or Trust Components will be decreased by such amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Subordination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The flow chart set forth under "*Summary of Terms—Offered Certificates—Distributions—D. Subordination, Allocation of Losses and Certain Expenses*" is hereby replaced with the following:

<sup>(1)</sup> The maximum certificate balances of Class A-2, Class A-3, Class A-S, Class B and Class C certificates (subject to the constraint on the aggregate initial certificate balance of the Class A-2 and Class A-3 trust components discussed above under "—*Certificate Balances and Notional Amounts*") will be issued on the closing date, and the certificate balance or notional amount of each other class of Exchangeable

Certificates will be equal to zero on the closing date. The relative priorities of the Exchangeable Certificates are described more fully under "*Description of the Certificates—Distributions*".

<sup>(2)</sup> The Class X-A, Class X-B, Class X-D, Class X-F and Class X-S certificates are interest-only certificates.

<sup>(3)</sup> Other than the Class X-D, Class X-F, Class X-S and Class R certificates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The section of the Preliminary Prospectus entitled "*Description of the Certificates—Subordination; Allocation of Realized Losses*" is hereby replaced with the following:

The rights of holders of the Subordinate Certificates to receive distributions of amounts collected or advanced on the Mortgage Loans and allocable to the Certificates (other than the Class R Certificates) will be subordinated, to the extent described in this prospectus, to the rights of holders of the Senior Certificates. In particular, the rights of the holders of the Class A-S Exchangeable Certificates, Class B Exchangeable Certificates and the Class C Exchangeable Certificates and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates to receive distributions of principal and/or interest, as applicable, will be subordinated to such rights of the holders of the Senior Certificates. The Class A-S Exchangeable Certificates will likewise be protected by the subordination of the Class B Exchangeable Certificates, the Class C Exchangeable Certificates and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates. The Class B Exchangeable Certificates will likewise be protected by the subordination of the Class C Exchangeable Certificates and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates. The Class C Exchangeable Certificates will likewise be protected by the subordination of the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates.

This subordination will be effected in two ways: (i) by the preferential right of the holders of a class of Certificates to receive on any Distribution Date the amounts of interest and/or principal allocable to the Certificates and distributable to them prior to any distribution being made on such Distribution Date in respect of any classes of certificates subordinate to that class (as described above under "*—Distributions—Priority of Distributions*"*)* and (ii) by the allocation of Realized Losses to classes of Certificates (other than the Class R certificates) that are subordinate to more senior classes, as described below.

No other form of credit support will be available for the benefit of the Offered Certificates.

Prior to the Cross-Over Date, allocation of principal that is allocable to the Certificates that are Principal Balance Certificates on any Distribution Date will be made *first*, to the Class A-2 Trust Component, until its Certificate Balance has been reduced to zero, and *second*, to the Class A-3 Trust Component, until its Certificate Balance has been reduced to zero. On or after the Cross-Over Date, allocation of principal will be made to the Class A-2 and Class A-3 Trust Components, in each case, that are still outstanding, *pro rata* (based upon their respective Certificate Balances) until their Certificate Balances have been reduced to zero. See "*—Distributions—Priority of Distributions*" above.

Allocation to the Class A-2 and Class A-3 Trust Components, for so long as they are outstanding, of the entire Principal Distribution Amount for each Distribution Date will have the effect of reducing the aggregate Certificate Balance of the Class A-2 and Class A-3 Trust Components at a proportionately faster rate than the rate at which the aggregate Stated Principal Balance of the pool of Mortgage Loans will decline. Therefore, as principal is distributed to the holders of the Class A-2 and Class A-3 Trust Components, the percentage

interest in the issuing entity evidenced by the Class A-2 and Class A-3 Trust Components will be decreased (with a corresponding increase in the percentage interest in the issuing entity evidenced by the Subordinate Certificates), thereby increasing, relative to their respective Certificate Balances, the subordination afforded to the Class A-2 and Class A-3 Trust Components by the Subordinate Certificates.

Following retirement of the Class A-2 and Class A-3 Trust Component, the successive allocation on each Distribution Date of the remaining Principal Distribution Amount to the Class A-S, Class B and Class C Trust Components and the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates, in that order, for so long as they are outstanding, will provide a similar, but diminishing benefit to those certificates (other than to the Class J-RR certificates) and Trust Components as to the relative amount of subordination afforded by the outstanding classes of certificates with later sequential designations.

On each Distribution Date, immediately following the distributions to be made to the Certificateholders on that date, the certificate administrator is required to calculate the Realized Loss for such Distribution Date.

The "<u>Realized Loss</u>" with respect to any Distribution Date is the amount, if any, by which (i) the aggregate Stated Principal Balance (for purposes of this calculation only, the aggregate Stated Principal Balance will not be reduced by the amount of principal payments received on the Mortgage Loans that were used to reimburse the master servicer, the special servicer or the trustee from general collections of principal on the Mortgage Loans for Workout-Delayed Reimbursement Amounts, to the extent those amounts are not otherwise determined to be Nonrecoverable Advances) of the Mortgage Loans, including any REO Loans (but in each case, excluding any Companion Loan) as of the related Determination Date is less than (ii) the then aggregate Certificate Balance of the Principal Balance Certificates after giving effect to distributions of principal on that Distribution Date. The certificate administrator will be required to allocate any Realized Losses among the respective classes of Principal Balance Certificates (other than any Exchangeable Certificates) and the Trust Components in the following order, until the Certificate Balance of each such class or Trust Component is reduced to zero:

*first*, to the Class J-RR certificates;

*second,* to the Class H-RR certificates;

*third,* to the Class G-RR certificates;

*fourth*, to the Class F certificates;

*fifth*, to the Class E certificates;

*sixth*, to the Class D certificates;

*seventh,* to the Class C Trust Component;

*eighth,* to the Class B Trust Component; and

*ninth*, to the Class A-S Trust Component.

Following the reduction of the Certificate Balances of all classes of Subordinate Certificates to zero, the certificate administrator will be required to allocate Realized Losses among the Class A-2 and the Class A-3 Trust Components, *pro rata*, based upon their

respective Certificate Balances, until their respective Certificate Balances have been reduced to zero.

Any Realized Loss applied to the Class A-2, Class A-3, Class A-S, Class B or Class C Trust Component will be allocated to the corresponding classes of Exchangeable Certificates with Certificate Balances *pro rata* to reduce their Certificate Balances in accordance with their Class Percentage Interests therein.

Realized Losses will not be allocated to the Class R certificates and will not be directly allocated to the Class X Certificates or the Exchangeable IO Certificates or the Exchangeable IO Trust Components. However, the Notional Amounts of the classes of Class X Certificates or Exchangeable IO Certificates or Exchangeable IO Trust Components will be reduced if the related classes of Principal Balance Certificates or Exchangeable P&I Trust Components are reduced by such Realized Losses.

In general, Realized Losses could result from the occurrence of: (1) losses and other shortfalls on or in respect of the Mortgage Loans, including as a result of defaults and delinquencies on the related Mortgage Loans, Nonrecoverable Advances made in respect of the Mortgage Loans, the payment to the special servicer of any compensation as described in "*Pooling and Servicing Agreement—Servicing and Other Compensation and Payment of Expenses*", and the payment of interest on Advances and certain servicing expenses; and (2) certain unanticipated, non-Mortgage Loan specific expenses of the issuing entity, including certain reimbursements to the certificate administrator or trustee as described under "*Transaction Parties—The Certificate Administrator and Trustee*", and certain federal, state and local taxes, and certain tax-related expenses, payable out of the issuing entity, as described under "*Material Federal Income Tax Considerations*".

Losses on each Whole Loan will be allocated to the related Mortgage Loan and the related Pari Passu Companion Loans (if any), *pro rata*, based upon their respective principal balances.

A class of Regular Certificates or a Trust Component will be considered outstanding until its Certificate Balance or Notional Amount, as the case may be, is reduced to zero. However, notwithstanding a reduction of its Certificate Balance to zero, reimbursements of any previously allocated Realized Losses are required thereafter to be made to a class of Principal Balance Certificates in accordance with the payment priorities set forth in "*—Distributions—Priority of Distributions*" above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Allocation of Yield Maintenance Charges and Prepayment Premiums</u>.

"<u>YM Denominator</u>" means, for any Distribution Date, the total amount of principal distributed to the Class D, Class E, Class F, Class G-RR, Class H-RR and Class J-RR certificates, the Class A-2 Exchangeable Certificates, the Class A-3 Exchangeable Certificates, the Class A-S Exchangeable Certificates, the Class B Exchangeable Certificates and the Class C Exchangeable Certificates for that Distribution Date.

Notwithstanding any of the foregoing to the contrary, if at any time the Certificate Balances of the Principal Balance Certificates (other than the Control Eligible Certificates) have been reduced to zero as a result of the allocation of principal payments on the Mortgage Loans, the certificate administrator will pay to the holders of each remaining Class of Principal Balance Certificates then entitled to distributions of principal on such Distribution Date the product of (a) any Yield Maintenance Charge or Prepayment Premium distributable on the subject Distribution Date (net of any Liquidation Fees payable therefrom) and (b) a fraction, the numerator of which is equal to the amount of principal distributed to such Class for that Distribution Date, and the denominator of which is the total amount of principal distributed to all Principal Balance Certificates for that Distribution Date.

"<u>Base Interest Fraction</u>" means, with respect to any principal prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge or Prepayment Premium, and with respect to any class of Principal Balance Certificates, a fraction (A) the numerator of which is the greater of (x) zero and (y) the difference between (i) the pass-through rate on that class, and (ii) the applicable Discount Rate and (B) the denominator of which is the difference between (i) the mortgage interest rate on the related Mortgage Loan and (ii) the applicable Discount Rate; *provided*, *however*, that:

● under no circumstances will the Base Interest Fraction be greater than one;

● if the Discount Rate referred to above is greater than or equal to the mortgage interest rate on the related Mortgage Loan and is greater than or equal to the pass-through rate on that class, then the Base Interest Fraction will equal zero; and

● if the Discount Rate referred to above is greater than or equal to the mortgage interest rate on the related Mortgage Loan and is less than the pass-through rate on that class, then the Base Interest Fraction will be equal to 1.0.

"<u>Discount Rate</u>" means, with respect to any principal prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge or Prepayment Premium—

● if a discount rate was used in the calculation of the applicable Yield Maintenance Charge or Prepayment Premium pursuant to the terms of the Mortgage Loan or REO Loan, that discount rate, converted (if necessary) to a monthly equivalent yield, or

● if a discount rate was not used in the calculation of the applicable Yield Maintenance Charge or Prepayment Premium pursuant to the terms of the Mortgage Loan or REO Loan, the yield calculated by the linear interpolation of the yields, as reported in Federal Reserve Statistical Release H.15 (519)—Selected Interest Rates under the heading "U.S. government securities/treasury constant maturities" for the week ending prior to the date of the relevant prepayment (or deemed prepayment), of U.S. Treasury constant maturities with a maturity date, one longer and one shorter, most nearly approximating the maturity date of that Mortgage Loan or REO Loan, such interpolated treasury yield converted to a monthly equivalent yield.

For purposes of the immediately preceding bullet, the certificate administrator or the master servicer will select a comparable publication as the source of the applicable yields of U.S. Treasury constant maturities if Federal Reserve Statistical Release H.15 is no longer published.

"<u>Prepayment Premium</u>" means, with respect to any Mortgage Loan, any premium, fee or other additional amount (other than a Yield Maintenance Charge) paid or payable, as the context requires, by a borrower in connection with a principal prepayment on, or other early collection of principal of, that Mortgage Loan or any successor REO Loan with respect thereto (including any payoff of a Mortgage Loan by a mezzanine lender on behalf of the subject borrower if and as set forth in the related intercreditor agreement).

"<u>Yield Maintenance Charge</u>" means, with respect to any Mortgage Loan, any premium, fee or other additional amount paid or payable, as the context requires, by a borrower in connection with a principal prepayment on, or other early collection of principal of, a Mortgage Loan, calculated, in whole or in part, pursuant to a yield maintenance formula or otherwise pursuant to a formula that reflects the lost interest, including any specified amount or specified percentage of the amount prepaid which constitutes the minimum amount that such Yield Maintenance Charge may be.

No Prepayment Premiums or Yield Maintenance Charges will be distributed to the holders of the Class X-S or Class R Certificates.

For a description of Yield Maintenance Charges, see "*Description of the Mortgage Pool—Certain Terms of the Mortgage Loans*" and "*Certain Legal Aspects of Mortgage Loans—Default Interest and Limitations on Prepayments*".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Exchangeable Certificates</u>. The section of the Preliminary Prospectus entitled "*Description of the Certificates—Distributions—Exchangeable Certificates*" is hereby replaced with the following:

Each class of Exchangeable Certificates may be exchanged for the corresponding classes of Exchangeable Certificates set forth next to such class in the table below, and vice versa. Following any exchange of one or more classes of Exchangeable Certificates (the applicable "<u>Surrendered Classes</u>") for one or more classes of other Exchangeable Certificates (the applicable "<u>Received Classes</u>"), the Class Percentage Interests (as defined below) of the outstanding Certificate Balances or Notional Amounts of the Corresponding Trust Components that are represented by the Surrendered Classes (and consequently their related Certificate Balances or Notional Amounts) will be decreased, and those of the Received Classes (and consequently their related Certificate Balances or Notional Amounts) will be increased. The dollar denomination of each of the Received Classes of certificates must be equal to the dollar denomination of each of the Surrendered Classes of certificates. No fee will be required with respect to any exchange of Exchangeable Certificates.

The maximum Certificate Balance or Notional Amount of each class of Class A-2 Exchangeable Certificates that could be issued in an exchange is equal to the Certificate Balance of the Class A-2 Trust Component, the maximum Certificate Balance or Notional Amount of each class of Class A-3 Exchangeable Certificates that could be issued in an exchange is equal to the Certificate Balance of the Class A-3 Trust Component, the maximum Certificate Balance or Notional Amount of each class of Class A-S Exchangeable Certificates that could be issued in an exchange is equal to the Certificate Balance of the Class A-S Trust Component, the maximum Certificate Balance or Notional Amount of each class of Class B Exchangeable Certificates that could be issued in an exchange is equal to the Certificate Balance of the Class B Trust Component, and the maximum Certificate Balance or Notional Amount of each class of Class C Exchangeable Certificates that could be issued in an exchange is equal to the Certificate Balance of the Class C Trust Component. The aggregate Certificate Balance of the Offered Certificates set forth on the cover page of this prospectus assumes that only the maximum Certificate Balances of Class A-2, Class A-3, Class A-S, Class B and Class C certificates (subject to the constraint on the aggregate initial Certificate Balance of the Class A-2 and Class A-3 Trust Components discussed in

footnote (6) to the table under "*Summary of the Certificates*") are issued on the Closing Date and that the Certificate Balance or Notional Amount of each other class of Exchangeable Certificates is equal to zero.

Each class of Class A-2 Exchangeable Certificates, Class A-3 Exchangeable Certificates, Class A-S Exchangeable Certificates, Class B Exchangeable Certificates and Class C Exchangeable Certificates will have a Certificate Balance or Notional Amount equal to its Class Percentage Interest multiplied by the Certificate Balance of the Class A-2 Trust Component, Class A-3 Trust Component, Class A-S Trust Component, Class B Trust Component or Class C Trust Component, respectively. Each class of Class A-2 Exchangeable Certificates, Class A-3 Exchangeable Certificates, Class A-S Exchangeable Certificates, Class B Exchangeable Certificates and Class C Exchangeable Certificates with a Certificate Balance will have the same approximate initial credit support, Assumed Final Distribution Date, weighted average life and expected principal window as the Class A-2 certificates, Class A-3 certificates, Class A-S certificates, Class B certificates or Class C certificates, respectively, shown above in the "*Summary of Certificates*" table.

Appraisal Reduction Amounts and Collateral Deficiency Amounts (and Realized Losses) allocated to each of the Class A-2, Class A-3, Class A-S, Class B or Class C Trust Components will be allocated to the corresponding classes of Exchangeable Certificates with Certificate Balances *pro rata* to notionally reduce (or reduce) their Certificate Balances in accordance with their Class Percentage Interests therein.

*Exchange Limitations*

A Certificateholder that owns Exchangeable Certificates and desires to make an exchange, but does not own Exchangeable Certificates that collectively are the required denominations of Surrendered Classes necessary to make the desired exchange for applicable Received Classes, may be unable to obtain other Exchangeable Certificates sufficient to compose the required denominations or may be able only to exchange a portion (if any) of its Exchangeable Certificates. Other Certificateholders may be unwilling to sell their Certificates at reasonable prices (or at any price) or may be unable to sell their Certificates, or Certificates may have been purchased or placed into other financial structures and thus may be unavailable for purchase in any secondary market. Such circumstances may prevent you from obtaining Exchangeable Certificates in the proportions necessary to effect an exchange.

Potential purchasers of Exchangeable Certificates should consider the tax characteristics of such certificates as further discussed under "*Material Federal Income Tax Considerations—Exchangeable Certificates*". The Trust Components will not be withdrawn from the Grantor Trust in connection with any exchange.

*Exchange Procedures*

If a holder of Exchangeable Certificates wishes to exchange its Exchangeable Certificates, the Certificateholder must notify the certificate administrator no later than three business days before the proposed exchange date via email to CCTCMBSBondAdmin@computershare.com. The exchange date can generally be any business day other than the first or last business day of the month. The notice must (i) be on the Certificateholder's letterhead, (ii) carry a medallion stamp guarantee and (iii) set forth the following information: the CUSIP number of both the Certificates to be exchanged and the Certificates to be received, the current Certificate Balance(s) or Notional Amount(s) and original Certificate Balance(s) or Notional Amount(s) of the Surrendered Classes and Received Classes, the Certificateholder's DTC participant number and the proposed

exchange date. A notice becomes irrevocable on the second business day before the proposed exchange date.

Subject to the satisfaction of the conditions to an exchange, including the procedures described above, upon the request of the holder of Exchangeable Certificates of the relevant class(es) and the surrender of such Exchangeable Certificates, the certificate administrator will be required to deliver the Exchangeable Certificates of the relevant class(es) to which that holder is entitled in the exchange. The certificate administrator will also reduce the outstanding Certificate Balance(s) or Notional Amount(s) of the Surrendered Classes, and increase the outstanding Certificate Balance(s) or Notional Amount(s) of the Received Classes, on the certificate register. The Certificateholder and the certificate administrator will utilize the Deposit and Withdrawal System at DTC to effect the exchange.

The first distribution on an Exchangeable Certificate received in an exchange transaction will be made on the first Distribution Date in the month following the month of the exchange to the Certificateholder of record as of the close of business on the last day of the month of the exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Decrement Tables</u>. The section of the Preliminary Prospectus entitled "*Yield and Maturity Considerations—Weighted Average Life*" is updated to replace the decrement tables for the Class A-3 certificates (maximum initial certificate balance and minimum initial certificate balance) and to add a decrement table for the Class A-S certificates, which applies equally to the Class A-S Exchangeable Certificates that have a Certificate Balance, as follows:

**<u>Credit Risk Retention Disclosure Updates</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The section of the Preliminary Prospectus entitled "*Credit Risk Retention—General*" is hereby updated as follows:

The estimated aggregate initial Certificate Balance of the Horizontal Risk Retention Certificates, $50,478,000, represents approximately 5.10% of the aggregate fair value of the certificates (other than the Class R certificates) as of the Closing Date, determined in accordance with GAAP, rather than 5.08%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The sub-section entitled "*Credit Risk Retention—Horizontal Risk Retention Certificates—General*" is hereby replaced with the following:

The Retaining Party is expected to purchase the Horizontal Risk Retention Certificates, consisting of the classes of certificates identified in the table below.

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp; **Class of Horizontal Risk Retention Certificates** | &nbsp;&nbsp; **Expected Initial Certificate Balance** | &nbsp;&nbsp; **Estimated Fair Values (in $) and Estimated Range of Fair Values (in %) of the Horizontal Risk Retention Certificates<sup>(1)</sup>** | &nbsp;&nbsp; **Expected Purchase Price<sup>(2)</sup>** |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The estimated fair value (expressed as a dollar amount) and estimated range of fair values (expressed
as a percentage of the aggregate fair value of all of the certificates (other than the Class R certificates)) of the Horizontal Risk Retention
Certificates. The fair value of the Horizontal Risk Retention Certificates have been determined as described under "— *Yield-Priced Certificates* ". The fair value of the other certificates is unknown and has been determined by the Retaining Sponsor as described
under "*—Determination of Amount of Required Horizontal Credit Risk Retention*" below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Expressed as a percentage of the expected initial Certificate Balance of each class of the Horizontal
Risk Retention Certificates, excluding accrued interest. The aggregate purchase price expected to be paid for the Horizontal Risk Retention
Certificates to be acquired by the Retaining Party is approximately $37,379,596, excluding accrued interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The approximate initial Certificate Balance of the Class G-RR certificates is estimated based in part
on the estimated ranges of Certificate Balances and estimated fair values described herein under "*Credit Risk Retention* ".
The Class G-RR certificates are expected to have an initial Certificate Balance that falls within a range of $7,342,000 and $10,096,000.
The Class G-RR certificates are expected to have an estimated fair value that falls within a range of approximately $5,893,150 and $7,044,513.

The aggregate fair value of the Horizontal Risk Retention Certificates is expected to be equal to or above 5.0% of the aggregate fair value, as of the Closing Date, of all of the certificates (other than the Class R certificates). The Retaining Sponsor estimates that, relying solely on retaining an "eligible horizontal residual interest" in order to meet the credit risk retention requirements of the Credit Risk Retention Rules with respect to this securitization transaction, it is required to retain an eligible horizontal residual risk retention interest with an aggregate fair value

dollar amount of between approximately $35,708,495 and $37,609,673, representing 5.0% of the aggregate fair value, as of the Closing Date, of all of the certificates (other than the Class R certificates).

A reasonable time after the Closing Date, the Retaining Sponsor will be required to disclose to, or cause to be disclosed to, Certificateholders the following: (a) the fair value of the Horizontal Risk Retention Certificates that will be retained by the Retaining Party based on actual sale prices and finalized tranche sizes, (b) the fair value of the "eligible horizontal residual interest" (as such term is defined in the Credit Risk Retention Rules) that the Retaining Sponsor would have been required to retain under the Credit Risk Retention Rules, and (c) to the extent the valuation methodology or any of the key inputs and assumptions that were used in calculating the fair value or range of fair values disclosed below under the heading "—Determination of Amount of Required Horizontal Credit Risk Retention" prior to the pricing of the certificates materially differs from the methodology or key inputs and assumptions used to calculate the fair value at the time of the Closing Date, descriptions of those material differences. Any such notice disclosures are expected to be included in a Current Report on Form 8-K on, or a reasonable period after, the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. The sub-section entitled "*Credit Risk Retention—Horizontal Risk Retention Certificates—Material Terms of the Eligible Horizontal Residual Interest*" is hereby replaced with the following:

On any Distribution Date, the aggregate amount available for distributions from the Mortgage Loans, net of specified servicing and administrative costs and expenses, will be distributed to the certificates and Trust Components in sequential order in accordance with their respective principal and interest entitlements (beginning with the Class X-A, Class X-B, Class X-D, Class X-F and Class X-S certificates and the Class A-2, Class A-2-X1, Class A-2-X2, Class A-3, Class A-3-X1 and Class A-3-X2 Trust Components), in each case as set forth under "*Description of the Certificates—Distributions—Priority of Distributions*". On any Distribution Date, Realized Losses on the Mortgage Loans will be allocated *first*, to the Class J-RR certificates, *second*, to the Class H-RR certificates, *third*, to the Class G-RR certificates, *fourth*, to the Class F certificates, *fifth*, to the Class E certificates, *sixth*, to the Class D certificates, *seventh*, to the Class C Trust Component, *eighth*, to the Class B Trust Component, *ninth*, to the Class A-S Trust Component, and *finally*, *pro rata* based on their respective Certificate Balances, to the Class A-2, Class A-3 Trust Components, in each case until the Certificate Balance of that class or Trust Component has been reduced to zero. Any Realized Loss applied to the Class A-2, Class A-3, Class A-S, Class B or Class C Trust Component will be allocated to the corresponding classes of Exchangeable Certificates with Certificate Balances *pro rata* to reduce their Certificate Balances in accordance with their Class Percentage Interests therein. See "*Description of the Certificates—Distributions—Priority of Distributions*" and "*Pooling and Servicing Agreement—The Directing Certificateholder*".

For a description of other material payment terms of the Classes of Yield-Priced Principal Balance Certificates identified in the table above in "—*General*", see "*Description of the Certificates*".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. The sub-section entitled "*Credit Risk Retention—Determination of Amount of Required Horizontal Credit Risk Retention*" is hereby replaced with the following:

General

CMBS such as the Principal Balance Certificates are typically priced based relative to either the treasury yield curve or to a targeted yield. The method of pricing used is primarily a function of the rating, but can also be determined by prevailing market conditions or investor preference. For this transaction, the Class A-2, Class A-3, Class A-S, Class B, Class C, Class D, Class E and Class F certificates (collectively, the "<u>Treasury-Priced Principal Balance Certificates</u>") are anticipated to be priced based on the treasury yield curve, and the Class G-RR, Class H-RR and Class J-RR certificates (the "<u>Yield-Priced Certificates</u>") are anticipated to be priced based on a targeted yield. The Retaining Sponsor calculated the expected scheduled principal payments (the "<u>Scheduled Certificate Principal Payments</u>") on each class of Treasury-Priced Principal Balance Certificates and each class of Yield-Priced Certificates as described below. CMBS such as the Class X-A, Class X-B, Class X-D, Class X-F and Class X-S certificates (solely for the purposes of this "*Credit Risk Retention*" section, the "<u>Treasury Yield Interest-Only Certificates</u>") are typically priced relative to the treasury yield curve. The Retaining Sponsor made its determination of the fair value of the Treasury-Priced Principal Balance Certificates and the Treasury Yield Interest-Only Certificates based on a number of inputs and assumptions consistent with these typical pricing methodologies in the manner described below for the applicable class of certificates. It should be noted in reviewing the fair value discussion below, that certain of the inputs and assumptions, such as yields, credit spreads, prices and coupons, are not directionally correlated. Variations from the base case in the direction of the high or low estimates will not necessarily occur in the same manner, in the same direction or to the same degree for each applicable input or assumption at any given point in time or as a result of any particular market condition. For example, with respect to any particular class of certificates, treasury yields may widen in the direction of the high estimate provided, while credit spreads may tighten in the direction of the low estimate provided.

Treasury-Priced Principal Balance Certificates

Based on the Structuring Assumptions and assuming a 0% CPR, the Retaining Sponsor calculated what the Scheduled Certificate Principal Payments on each Class of Treasury-Priced Principal Balance Certificates would be over the course of this securitization based on when principal payments were required to be made under the terms of the underlying mortgage loan documents during each Collection Period and which classes of Treasury-Priced Principal Balance Certificates would be entitled to receive principal payments based on the certificate payment priorities described in "*Description of the Certificates—Distributions—Priority of Distributions*". On the basis of the Scheduled Certificate Principal Payments, the Retaining Sponsor calculated the weighted average life for each class of Treasury-Priced Principal Balance Certificates.

Treasury Yield Curve

The Retaining Sponsor utilized the assumed treasury yield curve in the table below in determining the range of estimated fair values of the Treasury-Priced Principal Balance Certificates. The actual treasury yield curve that will be used as a basis for determining the price of the Treasury-Priced Principal Balance Certificates is not known at this time and differences in the treasury yield curve will ultimately result in higher or lower fair value calculations. For an expected range of values at specified points along the treasury yield curve, see the table below titled "Range of Treasury Yields for the Treasury-Priced Principal Balance Certificates". The Retaining Sponsor identified the range presented in the table

below at each maturity on the treasury yield curve, which represents the Retaining Sponsor's estimate of the largest increase or decrease in the treasury yield at that maturity reasonably expected to occur prior to pricing of the Treasury-Priced Principal Balance Certificates, based on 10 business day rolling periods over the past 6 months.

**Range of Treasury Yields for the Treasury-Priced Principal Balance Certificates**

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp; **Tenor** | &nbsp;&nbsp; **Low Estimate of Treasury Yield** | &nbsp;&nbsp; **Base Case Treasury Yield** | &nbsp;&nbsp; **High Estimate of Treasury Yield** |
| &nbsp;&nbsp;3YR | &nbsp;&nbsp;3.8238% | &nbsp;&nbsp;4.2044% | &nbsp;&nbsp;4.5850% |
| &nbsp;&nbsp;5YR | &nbsp;&nbsp;3.9686% | &nbsp;&nbsp;4.3290% | &nbsp;&nbsp;4.6894% |
| &nbsp;&nbsp;7YR | &nbsp;&nbsp;4.1540% | &nbsp;&nbsp;4.4995% | &nbsp;&nbsp;4.8450% |

---

Based on the treasury yield curve, the Retaining Sponsor will determine for each class of Treasury-Priced Principal Balance Certificates the treasury yield reflected on the treasury yield curve (the "<u>Interpolated Yield</u>") that corresponds to that class's weighted average life, by using a linear interpolation using the treasury yield curve with 3, 5 and 7 year maturities if the weighted average life does not correspond to a specified maturity on the treasury yield curve.

Credit Spread Determination

The Retaining Sponsor determined the credit spread for each class of Treasury-Priced Principal Balance Certificates on the basis of market bids obtained for similar CMBS with similar credit ratings, pool composition and asset quality, payment priority and weighted average lives of the related class of Treasury-Priced Principal Balance Certificates as of the date of this prospectus. The actual credit spread for a particular class of Treasury-Priced Principal Balance Certificates at the time of pricing is not known at this time and differences in the then-current credit spread demanded by investors for similar CMBS will ultimately result in higher or lower fair values. The Retaining Sponsor identified the range presented in the table below from the base case credit spread percentage, which represents the Retaining Sponsor's estimate of the largest increase or decrease in the credit spread for newly issued CMBS reasonably expected to occur prior to pricing of the Treasury-Priced Principal Balance Certificates based on the Retaining Sponsor's observation and experience in the placement of CMBS with similar characteristics.

Discount Yield Determination

The discount yield (the "<u>Discount Yield</u>") for each class of Treasury-Priced Principal Balance Certificates is the sum of the Interpolated Yield for such class and the related credit spread established at pricing. For an expected range of estimated values for each class of Treasury-Priced Principal Balance Certificates, see the table titled "*Range of Discount Yields for the Treasury-Priced Principal Balance Certificates*" below. The Retaining Sponsor identified the range presented in the table below for each such class of Treasury-Priced Principal Balance Certificates as the range from (i) the sum of the lowest estimated Interpolated Yield for that class and the lowest estimated credit spread to (ii) the sum of the highest estimated Interpolated Yield for that class and the highest estimated credit spread.

Determination of Class Sizes

The Retaining Sponsor was provided credit support levels for each class of Treasury-Priced Principal Balance Certificates by each Rating Agency. A credit support level for a particular class of Treasury-Priced Principal Balance Certificates reflects the Rating Agency's assessment of the aggregate Certificate Balance of Principal Balance Certificates that would be required to be subordinate to that class of Treasury-Priced Principal Balance Certificates in order to satisfy that Rating Agency's internal ratings criteria to permit it to issue a particular credit rating. Based on the individual credit support levels (expressed as a percentage) provided by the Rating Agencies, or a stipulation by the b-piece buyer, if applicable, the Retaining Sponsor determined the highest required credit support level of the Rating Agencies selected to rate a particular class of Treasury-Priced Principal Balance Certificates, or of the b-piece buyer, if applicable (the "<u>Constraining Level</u>"). In certain circumstances the Retaining Sponsor may have elected not to engage an NRSRO for particular Classes of Principal Balance Certificates, based in part on the credit support levels provided by that NRSRO. See "*Risk Factors—Other Risks Relating to the Certificates—Nationally Recognized Statistical Rating Organizations May Assign Different Ratings to the Certificates; Ratings of the Certificates Reflect Only the Views of the Applicable Rating Agencies as of the Dates Such Ratings Were Issued; Ratings May Affect ERISA Eligibility; Ratings May Be Downgraded*"*.* The aggregate Certificate Balance for the Class A-2 and Class A-3 Exchangeable Certificates was determined by multiplying the Initial Pool Balance by a percentage equal to 1.0 minus 0.3. The Certificate Balance for the Class A-S certificates was determined by multiplying the Initial Certificate Balance by a percentage equal to 1.0 minus such class's Constraining Level, minus the percentage of the Initial Certificate Balance represented by the aggregate Certificate Balance of the Class A-2 and Class A-3 Certificates. For each other subordinate class of Treasury-Priced Principal Balance Certificates, that class's Certificate Balance was determined by multiplying the Initial Pool

Balance by a percentage equal to the difference between the credit support level for the immediately senior class of Treasury-Priced Principal Balance Certificates and such subordinate class's Constraining Level, except in the case of the and Class F certificates, in which case the Certificate Balance was determined by multiplying the Initial Pool Balance by a percentage equal to the difference between the credit support level for the immediately senior class and a percentage determined such that the fair value of the Horizontal Risk Retention Certificates equals at least 5% of the aggregate fair value of the certificates.

For purposes of the calculations in this "*Credit Risk Retention*" section, the Certificate Balances of the Class A-2 and Class A-3 certificates are assumed to be $250,000,000 and $263,950,000, respectively.

Target Price Determination

The Retaining Sponsor determined a target price (the "<u>Target Price</u>") or target coupon (the "<u>Target Coupon</u>") for each class of Treasury-Priced Principal Balance Certificates on the basis of the price (expressed as a percentage of the Certificate Balance of that class) that similar CMBS with similar credit ratings, cash flow profiles and prepayment risk have priced at in recent securitization transactions or, with respect to a Target Coupon, on the basis of the coupon associated with similar CMBS with similar credit ratings, cash flow profiles and prepayment risk in recent securitization transactions. The Target Price or Target Coupon, as applicable, that was utilized for each class of Treasury-Priced Principal Balance Certificates is set forth in the table below. The Target Prices and Target Coupons utilized by the Retaining Sponsor have not changed materially during the prior year.

Determination of Assumed Certificate Coupon

With respect to each class of Treasury-Priced Principal Balance Certificates, based on the Target Price, the Discount Yield and the Scheduled Certificate Principal Payments for each class of Treasury-Priced Principal Balance Certificates, the Retaining Sponsor determined the assumed certificate coupon (the "<u>Assumed Certificate Coupon</u>") by calculating what coupon would be required to be used based on the Scheduled Certificate Principal Payments for such class of certificates in order to achieve the related Target Price for that class of certificates when utilizing the related Discount Yield in determining that Target Price. The Assumed Certificate Coupon with respect to the Class D, Class E and Class F certificates is equal to the related Target Coupon. The Assumed Certificate Coupon for each class of certificates and range of Assumed Certificate Coupons generated as a result of the range of possible Discount Yields as of the Closing Date is set forth in the table below.

Determination of Treasury-Priced Expected Price

Based on the Assumed Certificate Coupons, the Discount Yield and the Scheduled Certificate Principal Payments for each class of Treasury-Priced Principal Balance Certificates, the Retaining Sponsor determined the price (the "<u>Treasury-Priced Expected Price</u>") expressed as a percent of the certificate balance of that class by determining the net present value of the Scheduled Certificate Principal Payments and interest accruing at the related Assumed Certificate Coupon discounted at the related Discount Yield.

Treasury Yield Interest-Only Certificates

Based on the Structuring Assumptions and assuming a 100% CPY prepayment rate and 1% clean-up call (or a 0% CPY prepayment rate with respect to the Class X-S certificates), the Retaining Sponsor calculated what the expected scheduled interest payments on each class of Treasury Yield Interest-Only Certificates would be over the course of the transaction (for each class of certificates, the "<u>Scheduled Certificate Interest Payments</u>") based on what the Notional Amount of the related class of Treasury Yield Interest-Only Certificates would be during each Collection Period as a result of the application of the expected principal payments during such Collection Period under the terms of the underlying Mortgage Loan documents and the payment priorities described in "*Description of the Certificates—Distributions—Priority of Distributions*". On the basis of the periodic reduction in the Notional Amount of each Class of Treasury Yield Interest-Only

Certificates, the Retaining Sponsor calculated the weighted average life for each such class of Treasury Yield Interest-Only Certificates.

Treasury Yield Curve

The Retaining Sponsor utilized the assumed treasury yield curve in the table below in determining the range of estimated fair value for the Treasury Yield Interest-Only Certificates. The actual treasury yield curve that will be used as a basis for determining the price of the Treasury Yield Interest-Only Certificates is not known at this time and differences in the treasury yield curve will ultimately result in higher or lower fair value calculations. For an expected range of values at specified points along the treasury yield curve, see the table below titled "*Range of Treasury Yield Curve Values*". The Retaining Sponsor identified the range presented in the table below at each maturity on the treasury yield curve, which represents the Retaining Sponsor's estimate of the largest increase or decrease in the treasury yield at that maturity reasonably expected to occur prior to pricing of the Treasury Yield Interest-Only Certificates, based on 10 business day rolling periods over the past 6 months.

| &nbsp;&nbsp;5YR | &nbsp;&nbsp;3.9686% | &nbsp;&nbsp;4.3290% | &nbsp;&nbsp;4.6894% |

---

Based on the treasury yield curve, the Retaining Sponsor will determine for each class of Treasury Yield Interest-Only Certificates the yield reflected on the treasury yield curve (the "<u>Interpolated Yield</u>") that corresponds to that class's weighted average life, by using a linear interpolation using treasury yield curves with 3 and 5 year maturities if the weighted average life does not correspond to a specified maturity on the treasury yield curve.

Credit Spread Determination

The Retaining Sponsor determined the credit spread for each class of Treasury Yield Interest-Only Certificates on the basis of market bids obtained for similar CMBS with similar credit ratings, pool composition and asset quality, payment priority and weighted average lives of such class of Treasury Yield Interest-Only Certificates as of the date of this prospectus. The actual credit spread for a particular class of Treasury Yield Interest-Only Certificates at the time of pricing is not known at this time and differences in the then-current credit spread demanded by investors for similar CMBS will ultimately result in higher or lower fair values. The Retaining Sponsor identified the range presented in the table below from the base case credit spread percentage, which is the Retaining Sponsor's estimate of the largest increase or decrease in the credit spread for newly issued CMBS reasonably expected to occur prior to pricing of the certificates based on the Retaining Sponsor's experience in the placement of CMBS with similar characteristics.

Discount Yield Determination

Discount Yield for each class of Treasury Yield Interest-Only Certificates is the sum of the Interpolated Yield for such class and the related credit spread. For an expected range of values for each class of Treasury Yield Interest-Only Certificates, see the table titled "*Range of Discount Yields for the Treasury Yield Interest-Only Certificates*" below. The Retaining Sponsor identified the range presented in the table below for each such class of certificates as the range from (i) the sum of the lowest estimated Interpolated Yield for that class and the lowest estimated credit spread to (ii) the sum of the highest estimated Interpolated Yield for that class and the highest estimated credit spread.

Determination of Scheduled Certificate Interest Payments

Based on the range of Assumed Certificate Coupons determined for the Treasury-Priced Principal Balance Certificates, the Retaining Sponsor determined the range of Scheduled Certificate Interest Payments for each scenario for each Class of Treasury Yield Interest-Only Certificates (except for the Class X-S certificates) based on the difference between the WAC Rate in effect from time to time, over the weighted average of the Pass-Through Rate(s) of the underlying Class(es) of Treasury-Priced Principal Balance Certificates upon which the Notional Amount of such Class of Treasury Yield Interest-Only Certificates is based. The Pass-Through rate for the Class X-S certificates for any Distribution Date will be a *per annum* rate equal to 0.10140%.

Determination of Treasury Yield Interest-Only Expected Price

Based on the Discount Yield and the Scheduled Certificate Interest Payments for each class of Treasury Yield Interest-Only Certificates, the Retaining Sponsor determined the price (the "<u>Treasury Yield Interest-Only Expected Price</u>") expressed as a percent of the Notional Amount of that class by determining the net present value of the Scheduled Certificate Interest Payments discounted at the related Discount Yield. The Retaining Sponsor determined the Treasury Yield Interest-Only Expected Price for each class of Treasury Yield Interest-Only Certificates based on the low estimate and high estimate of Assumed Certificate Coupons. The lower the Assumed Certificate Coupon for the Principal

Balance Certificates, the higher the corresponding Treasury Yield Interest-Only Expected Price for a class of certificates will be, therefore, the low range of estimated fair values of the Treasury Yield Interest-Only Certificates will correspond to the high range of the estimate of Assumed Certificate Coupons for the Principal Balance Certificates and correspondingly, the high range of estimated fair values of the Treasury Yield Interest-Only Certificates will correspond to the low range of the estimate of Assumed Certificate Coupons for the Principal Balance Certificates.

Yield-Priced Certificates

The Yield-Priced Certificates are anticipated to be acquired by the Retaining Party based on a targeted discount yield of 13.00% in the base case estimate (11.00% in the low estimate and 14.50% in the high estimate) for each class of Yield-Priced Certificates, an Assumed Certificate Coupon equal to the WAC Rate class of Yield-Priced Certificates, the Structuring Assumptions and 0% CPY, each as agreed among the sponsor and the Retaining Party.

Determination of Class Size

The Retaining Sponsor determined the Certificate Balance or Notional Amount, as applicable, of each class of Yield-Priced Certificates in the same manner described above under "*—Determination of Amount of Required Horizontal Credit Risk Retention—Treasury-Priced Principal Balance Certificates—Determination of Class Sizes*".

Determination of Yield-Priced Expected Price

Based on the Assumed Certificate Coupons, the targeted discount yield and the Scheduled Certificate Principal Payments for each class of Yield-Priced Certificates, the Retaining Sponsor determined the price (the "<u>Yield-Priced Expected Price</u>") expressed as a percent of the Certificate Balance of that class by determining the net present value of the Scheduled Certificate Principal Payments and interest accruing at the related Assumed Certificate Coupon discounted at the related Discount Yield.

Calculation of Estimated Fair Value

Based on the Treasury-Priced Expected Prices, the Treasury Yield Interest-Only Expected Prices and the Yield-Priced Expected Prices, as applicable, the Retaining Sponsor determined the estimated fair value of each class of certificates (other than the Class R certificates) by multiplying the range of the Treasury-Priced Expected Prices, the Treasury Yield Interest-Only Expected Prices and the Yield-Priced Expected Prices, as applicable, by the related Certificate Balance or Notional Amount. The Retaining Sponsor determined the range of estimated fair values for each class of certificates based on the low estimate and high estimate of expected prices.

<sup>(1)</sup> The approximate initial Certificate Balances of the Class A-2 and Class A-3 certificates are unknown and will be determined based on the final pricing of those Classes of Certificates. However, the respective initial Certificate Balances of the Class A-2 certificates are expected to be within a range of $0 to $250,000,000, and the respective initial Certificate Balances of the Class A-3 certificates are expected to be within a range of $263,950,000 to $513,950,000. In the event that the Class A-3 certificates are issued with an initial certificate balance of $513,950,000, the Class A-2 certificates will not be issued. The aggregate initial Certificate Balance of the Class A-2 and Class A-3 certificates is expected to be approximately $513,950,000, subject to a variance of plus or minus 5%. For purposes of providing the range of estimated fair values for the certificates in the table above, the Certificate Balance of the Class A-2 certificates is assumed to be $250,000,000 and the Certificate Balance of the Class A-3 certificates is assumed to be $263,950,000.

<sup>(2)</sup> The approximate initial Certificate Balance of the Class F certificates is estimated based in part on the estimated ranges of Certificate Balances and estimated fair values described under this "Credit Risk Retention" section. The initial Certificate Balance of the Class F certificates is expected to fall within a range of $7,342,000 and $10,096,000, with the ultimate Certificate Balance determined such that the aggregate fair value of the Yield-Priced Certificates will equal at least 5% of the estimated fair value of all the certificates (other than the Class R certificates). Any variation in the initial Certificate Balance of the Class F certificates would affect the initial Notional Amount of the Class X-F certificates.

<sup>(3)</sup> The approximate initial Certificate Balance of the Class G-RR Certificates is estimated based in part on the estimated ranges of Certificate Balances and estimated fair values described under this "Credit Risk Retention" section. The initial Certificate Balance of the Class G-RR certificates is expected to fall within a range of $7,342,000 and $10,096,000, with the ultimate Certificate Balance determined such that the aggregate fair value of the Yield-Priced Certificates will equal at least 5% of the estimated fair value of all the certificates (other than the Class R certificates).

The estimated range of fair values for all the certificates (other than the Class R certificates) is approximately $714,169,894 to $752,193,468.
