Notwithstanding any other terms of this Indenture Supplement, the Series 2017-GT1 Term Notes, any other Transaction Documents or otherwise, the obligations of the Issuer under the Series 2017-GT1 Term Notes, this Indenture Supplement and each other Transaction Document to which it is a party are limited recourse obligations of the Issuer, payable solely from the Trust Estate, and following realization of the Trust Estate and application of the proceeds thereof in accordance with the terms of this Indenture Supplement, none of the Noteholders of Series 2017-GT1 Term Notes, the Indenture Trustee or any of the other parties to the Transaction Documents shall be entitled to take any further steps to recover any sums due but still unpaid hereunder or thereunder, all claims in respect of which shall be extinguished and shall not thereafter revive.  No recourse shall be had for the payment of any amount owing in respect of the Series 2017-GT1 Term Notes or this Indenture Supplement or for any action or inaction of the Issuer against any officer, director, employee, shareholder, stockholder or incorporator of the Issuer or any of their successors or assigns for any amounts payable under the Series 2017-GT1 Term Notes or this Indenture Supplement.  It is understood that the foregoing provisions of this Section 13 shall not (a) prevent recourse to the Trust Estate for the sums due or to become due under any security, instrument or agreement which is part of the Trust Estate, including, without limitation, the PC Guaranty and the PMT Guaranty or (b) save as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by the Series 2017-GT1 Term Notes or secured by this Indenture Supplement.  It is further understood that the foregoing provisions of this Section 13 shall not limit the right of any Person to name the Issuer as a party defendant in any proceeding or in the exercise of any other remedy under the Series 2017-GT1 

Term Notes or this Indenture Supplement, so long as no judgment in the nature of a deficiency judgment or seeking personal liability shall be asked for or (if obtained) enforced against any such Person or entity.

Section 14.    Owner Trustee Limitation of Liability.

It is expressly understood and agreed by the parties hereto that (a) this Indenture Supplement is executed and delivered by Wilmington Savings Fund Society, FSB d/b/a Christiana Trust (“Christiana”), not individually or personally, but solely as trustee of the Issuer, in the exercise of the powers and authority conferred and vested in it, (b) each of the representations, warranties, undertakings and agreements herein made on the part of the Issuer is made and intended not as personal representations, warranties, undertakings and agreements by Christiana, but is made and intended for the purpose of binding only the Issuer, (c) nothing herein contained shall be construed as creating any liability on Christiana, individually or personally, to perform any covenant either expressed or implied contained herein, all such liability, if any, being expressly waived by the parties hereto and by any Person claiming by, through or under the parties hereto, (d) Christiana has made no investigation as to the accuracy or completeness of any representations or warranties made by the Issuer in this Agreement and (e) under no circumstances shall Christiana, be personally liable for the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of any obligation, representation, warranty or covenant made or undertaken by the Issuer under this Indenture Supplement or the other Transaction Documents.

Section 15.    Credit Risk Retention.

To the extent the regulations required under Section 15G of the 1934 Act, added pursuant to Section 941(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Regulation RR”), apply to the issuance of the Series 2017-GT1 Term Notes and PLS is deemed a securitizer for purposes of Regulation RR, PLS shall maintain a subordinated seller’s interest in the Issuer (in the form of the Owner Trust Certificate) that equals not less than 5% of the aggregate unpaid principal balance of the Notes (other than Notes held to maturity by PLS or its wholly owned affiliates), calculated in accordance with Regulation RR.

The seller’s interest expected to be retained by PLS in connection with Regulation RR (to the extent applicable), will equal approximately 72.42% or $289,690,987 (in each case, as calculated in accordance with Regulation RR), as of the Issuance Date.  As the Series 2016-MSRVF1 Notes have not been issued and are held by PLS and financed by CSFB, the Note Balance of the Series 2016-MSRVF1 Notes is not included in the denominator of the calculation that produced the percentage described above in accordance with Regulation RR.  If the Note Balance of the Series 2016-MSRVF1 Notes were included in the denominator, the resulting percentage of the seller’s interest would be lower but still in excess of the required 5%.
