III.       EU RISK RETENTION

1.Natixis Real Estate Capital LLC will covenant and represent to the issuing entity, the underwriters, the depositor, the certificate administrator and the trustee that it will retain a material net economic interest in the securitization for the purpose of the EU risk retention requirements.

2.The following section is added to the Preliminary Prospectus:

EU Securitization Risk Retention Requirements

The Retaining Party will enter into on the Closing Date an agreement with the issuing entity, the underwriters, the depositor, the certificate administrator and the trustee (the “Credit Risk Retention Agreement”) under which such Retaining Party will, among other things, give certain covenants and representations for the purpose of the EU Retention Requirements.

“EU Retention Requirements” means, together, the risk retention requirements set out in:

(a)Articles 404 to 410 of the European Union Regulation (EU) No 2013/575/EU (the “Capital Requirements Regulation”), as supplemented by Commission Delegated Regulation (EU) No 625/2014, including any further technical standards and guidance published in relation thereto as may be effective from time to time;

(b)Articles 254-257 of the European Union Regulation (EU) No 2015/35 (the “Solvency II Regulation”), including any technical standards and guidance published in relation thereto as may be effective from time to time; and

(c)Articles 50-56 of Commission Delegated Regulation (EU) No 231/2013 (the “AIFM Regulation”), including any technical standards and guidance published in relation thereto as may be effective from time to time.

Under the Credit Risk Retention Agreement, the Retaining Party will covenant for the benefit of the issuing entity, the underwriters, the depositor, the certificate administrator and the trustee, for so long as any certificates are outstanding:

(a)to hold and retain as originator on an ongoing basis a material net economic interest in the transaction described in this prospectus in the form specified in paragraph (a) of Article 405(1) of the Capital Requirements Regulation as supplemented by Article 5(1)(c) of Commission Delegated Regulation (EU) No 625/2014, which provides that a retention in the form specified in paragraph (a) of Article 405(1) may also be achieved by retention of a vertical tranche which has a nominal value of no less than 5% of the total nominal value of each of the tranches sold or transferred to investors (the “Retention Covenant”);

(b)that neither it nor any of its affiliates will sell, transfer, hedge or otherwise mitigate its credit risk (including in connection with the entry into any financing arrangements) under or associated with its net economic interest specified in paragraph (a) or the portfolio of mortgage loans, where to do so would cause the transaction described in this prospectus to cease to be compliant with the EU Retention Requirements (the “Hedging Covenant”);

(c)subject to any regulatory requirements, (i) to take such further action, provide such information, on a confidential basis, (including the information referred to in Article 409 of the Capital Requirements Regulation, Article 52(e) and (f) of the AIFM Regulation or Article 256(d) of the Solvency II Regulation) and enter into such other agreements in each case as may reasonably be required to satisfy the EU Retention Requirements; provided that the Retaining Party will not be in breach of this covenant if it fails to comply due to events, actions and circumstances beyond its control and (ii) to provide to the issuing entity, on a confidential basis, information in the possession of the Retaining Party relating to its holding of the RRI Interest, at the cost and expense of the party seeking such information, and to the extent the same under

 -5-

sub-clause (i) or (ii) of this section is not subject to a duty of confidentiality, at any time prior to the maturity of the certificates;

(d)to confirm its continued compliance with the covenant set out at sub-paragraph (a) and (b) above to the issuing entity, the underwriters, the depositor, the trustee and the certificate administrator, in each case in writing (which may be by way of e-mail) upon the request of the issuing entity, the certificate administrator or the trustee (A) following a material change in the performance of the certificates or the risk characteristics of the certificates or of the underlying portfolio of Mortgage Loans and (B) following a breach of the obligations included in the PSA of which the Retaining Party is aware; and

(e)to notify promptly the issuing entity, the trustee, the certificate administrator and the directing certificateholder if for any reason (i) it ceases to hold the amount of the RRI Interest specified as to be purchased and retained by the Retaining Party under “U.S. Credit Risk Retention—General” above in accordance with clause (a) above, (ii) it fails to comply with the covenant set out in clause (b) above in any respect, (iii) it fails to comply with the covenant set out in clause (c) above in any material respect, or (iv) any of the representations and warranties of such Retaining Party contained in the Credit Risk Retention Agreement were untrue on the date given.

Under the Credit Risk Retention Agreement, the Retaining Party will represent and warrant to the issuing entity, the underwriters, the depositor and the trustee that in relation to each Mortgage Loan sold by the Retaining Party, either (i) the Retaining Party purchased such Mortgage Loan for its own account prior to selling it to the depositor in accordance with Article 4(1)(13)(b) of the Capital Requirements Regulation; or (ii) the Retaining Party either itself or through related entities, directly or indirectly, was involved in the original agreement which created such Mortgage Loan in accordance with Article 4(1)(13)(b) of the Capital Requirements Regulation.

The issuing entity, the underwriters, the depositor and the trustee are each parties to the Credit Risk Retention Agreement solely for the purposes of obtaining the benefit of the representations, warranties and covenants contained therein and under no circumstances will any of them be deemed to have undertaken any obligations thereunder or by virtue of their entry into the Credit Risk Retention Agreement.

Under the PSA, the certificate administrator will include in each Distribution Date Statement a statement that there is available on the website of the certificate administrator information regarding ongoing compliance by the Retaining Party with the Retention Covenant and the Hedging Covenant, which will be posted on the “Risk Retention Compliance” tab of the certificate administrator’s website. The certificate administrator will post on such tab the following statements provided to it by the Retaining Party, specified as follows:

(a)the original principal amount of the RRI Interest of which the Retaining Party is the registered holder and whether such amount matches that amount which the Retaining Party has committed to retain under the Credit Risk Retention Agreement; and

(b)(i) unless the Retaining Party has provided notice to the contrary in respect of such Retaining Party, a statement (without verification) that the RRI Interest of such Retaining Party is complying with the Hedging Covenant and (ii) in the case that the certificate administrator has received a notification that such Retaining Party has failed to comply with the Hedging Covenant, a statement of such non-compliance and all details in relation to the same contained in such notification.

Mortgage Loans representing 48.0% of the Initial Pool Balance were originated by the Retaining Party. Pursuant to a mortgage loan purchase agreement dated as of December 8, 2016, (the “Retaining Party Mortgage Loan Purchase Agreement”) the Retaining Party purchased from Column a Mortgage Loan (the “Column Mortgage Loan”) representing 4.1% of the Initial Pool Balance, which will be sold by the Retaining Party to the depositor pursuant to the terms of the MLPA on the Closing Date. For the period of time between the purchase by the Retaining Party and its sale to the depositor, the Retaining Party will have been exposed to the credit risk and market risk of the Column Mortgage Loan.

3.The following section is added under “Risk Factors” in the Preliminary Prospectus.

EU Risk Retention and Due Diligence Requirements

Investors should be aware of the risk retention and due diligence requirements in Europe (the “EU Risk Retention and Due Diligence Requirements”) which currently apply, or are expected to apply in the future, in respect of various types of EU regulated investors including credit institutions, authorized alternative investment fund managers, investment firms, insurance and reinsurance undertakings, management companies and funds regulated pursuant to the Undertakings for Collective Investments in Transferable Securities (UCITS) Directive and institutions for occupational retirement provision. Among other things, such requirements restrict an investor who is subject to the EU Risk Retention and Due Diligence Requirements from investing in securitizations unless: (i) the originator, sponsor or original lender in respect of the relevant securitization has explicitly disclosed that it will retain, on an on-going basis, a net economic interest of not less than five percent in respect of certain specified credit risk tranches or securitized exposures; and (ii) such investor is able to demonstrate that they have undertaken certain due diligence in respect of various matters including but not limited to its note position, the underlying assets and (in the case of certain types of investors) the relevant sponsor or originator.

Each investor subject to the EU Risk Retention and Due Diligence Requirements should consult with its own legal, accounting, regulatory and other advisors and/or its regulator to determine whether, and to what extent, the information set out in this prospectus and in any investor report provided in relation to the transaction is sufficient for the purpose of satisfying the EU Risk Retention and Due Diligence Requirements. None of the originators, the issuing entity, the depositor, the trustee, the certificate administrator, the underwriters, their respective affiliates or any other person makes any representation, warranty or guarantee that any such information is sufficient for such purposes or any other purpose or that the structure of the offered certificates and the transactions described herein are compliant with the EU Risk Retention and Due Diligence Requirements or any other applicable legal regulatory or other requirements and no such person will have any liability to any prospective investor or any other person with respect to any deficiency in such information or any failure of the transactions contemplated hereby to comply with or otherwise satisfy such requirements. Investors are required to independently assess and determine the sufficiency of such information.

If a regulator determines that the transaction does not comply or, as a result of a breach by an entity that has covenanted to retain a net economic interest of such covenant, is no longer in compliance with, the EU Risk Retention and Due Diligence Requirements, an investor subject to the EU Risk Retention and Due Diligence Requirements may be subject to regulatory penalties and, in the case that such investor is subject to regulatory capital requirements, a punitive capital charge may apply in respect of the offered certificates held by it. Such a determination could have a negative impact on the price and liquidity of the offered certificates in the secondary market.

On 30 September 2015, the European Commission published a proposal to amend the CRR (the “Draft CRR Amendment Regulation”) and a proposed regulation relating to a European framework for simple, transparent and standardized securitization (such proposed regulation, including any implementing regulation, technical standards and official guidelines related thereto, the “Securitization Framework” and, together with the Draft CRR Amendment Regulation, the “Securitization Regulation”) which would, among other things, re-cast the EU risk retention rules as part of wider changes to establish a “Capital Markets Union” in Europe. The Presidency of the Council of Ministers of the European Union has also published compromise proposals concerning the Securitization Regulation. The Securitization Regulation will need to be considered, finalized and adopted by the European Parliament and Council of Ministers. It is unclear at this time when the Securitization Regulation will become effective. Investors should be aware that there are material differences between the current EU Risk Retention and Due Diligence Requirements and the Securitization Regulation. The Securitization Regulation may also enter into force in a form that differs from the published proposals and drafts.

There can therefore be no assurances as to whether the transactions described herein will be affected by a change in law or regulation relating to the EU Risk Retention and Due Diligence Requirements (including the Securitization Regulation), including as a result of any changes recommended in future reports or reviews. Investors should therefore make themselves aware of the EU Risk Retention and Due Diligence Requirements, the proposed Securitization Regulation (and any

 -7-

corresponding implementing rules of their regulator), in addition to any other regulatory requirements that are (or may become) applicable to them and/or with respect to their investment in the offered certificates.

4.The following bullet point contained in “Risk Factors—Legal and Regulatory Provisions Affecting Investors Could Adversely Affect the Liquidity of the Offered Certificates” in the Preliminary Prospectus is deleted in its entirety.

· Investors should be aware of the risk retention and due diligence requirements in Europe (the “EU Risk Retention and Due Diligence Requirements”) which currently apply, or are expected to apply in the future, in respect of various types of European Union regulated investors including credit institutions, authorized alternative investment fund managers, investment firms, insurance and reinsurance undertakings and UCITS funds. Amongst other things, such requirements restrict an investor who is subject to the EU Risk Retention and Due Diligence Requirements from investing in securitizations unless: (i) the originator, sponsor or original lender in respect of the relevant securitization has explicitly disclosed that it will retain, on an on-going basis, a net economic interest of not less than five percent in respect of certain specified credit risk tranches or securitized exposures; and (ii) such investor is able to demonstrate that they have undertaken certain due diligence in respect of various matters including but not limited to its note position, the underlying assets and (in the case of certain types of investors) the relevant sponsor or originator. Failure to comply with one or more of the requirements may result in various penalties including, in the case of those investors subject to regulatory capital requirements, the imposition of a punitive capital charge on the Certificates acquired by the relevant investor.

On 30 September 2015, the European Commission published a proposal to amend the EU Risk Retention and Due Diligence Requirements (the “Draft CRR Amendment Regulation”) and a proposed regulation relating to a European framework for simple, transparent and standardized securitization (such proposed regulation, including any implementing regulation, technical standards and official guidelines related thereto, the “Securitization Framework” and, together with the Draft CRR Amendment Regulation, the “Securitization Regulation”) which would, amongst other things, re-cast the European Union risk retention rules as part of wider changes to establish a “Capital Markets Union” in Europe. The Presidency of the Council of Ministers of the European Union has also published compromise proposals concerning the Securitization Regulation. The Securitization Regulation will need to be considered, finalized and adopted by the European Parliament and Council of Ministers. It is unclear at this time when the Securitization Regulation will become effective. Investors should be aware that there are material differences between the current EU Risk Retention and Due Diligence Requirements and the Securitization Regulation. The Securitization Regulation may also enter into force in a form that differs from the published proposals and drafts.

None of the sponsors, the depositor or the issuing entity intends to retain a material net economic interest in the securitization constituted by the issue of the offered certificates in accordance with the EU Risk Retention and Due Diligence Requirements or to take any other action which may be required by EEA-regulated investors for the purposes of their compliance with the EU Risk Retention and Due Diligence Requirements or similar requirements. Consequently, the offered certificates are not a suitable investment for EEA-credit institutions, investment firms or the other types of EEA regulated investors mentioned above. As a result, the price and liquidity of the offered certificates in the secondary market may be adversely affected. EEA-regulated investors are encouraged to consult with their own investment and legal advisors regarding the suitability of the offered certificates for investment.
