 Global-E Online Ltd. 
 Share Purchase Warrant 

Global-E Online Ltd., a company incorporated under the laws of the State of Israel (the
“Company,” and which shall include any corporation or other entity that succeeds to the Company’s obligations under this Warrant (this “Warrant”), whether by permitted assignment, by merger or consolidation or
otherwise), for value received, hereby certifies that Shopify International Limited, a corporation governed by the laws of Ireland, or its registered assigns (the “Registered Holder”), is entitled, subject to the terms set forth
below and including the terms relating to vesting and exercise set forth on Exhibit A attached hereto, to purchase from the Company, at any time after the date hereof and on or before the Expiration Date (as defined in
Section 8) the number of Company’s ordinary shares (the “Ordinary Shares”) at a price of $0.01 per share. The Ordinary Shares purchasable upon exercise of this Warrant, and the purchase price per share, each as adjusted
from time to time pursuant to the provisions of this Warrant, are hereinafter referred to as the “Warrant Shares” and the “Purchase Price,” respectively. 

This Warrant is issued pursuant to, and is subject to the terms and conditions of, the Service and Partnership Agreement between the Company
and Shopify Inc. dated as of April 12, 2021 (the “Agreement”) and as part of the consideration thereunder. 
 Warrant
No. 3 (“Warrant No. 3”) was originally issued to Shopify Inc., an affiliate of the Registered Holder, on April 12, 2021 (the “Original Issuance Date”) and was assigned on the date hereof
by Shopify Inc. to the Registered Holder, and Warrant No. 4 (“Warrant No. 4” and, collectively with Warrant No. 3, the “Original Warrants”) was originally issued to the Registered Holder
on the Original Issuance Date. 
 The Registered Holder partially exercised on the date hereof the Original Warrants, and this Warrant is
issued pursuant to Section 2(c) of the Original Warrants as a Replacement Warrant (as defined therein) for the Original Warrants. 

The following is a statement of the rights of the Registered Holder and the conditions to which this Warrant is subject, and to which the
Registered Holder, by the acceptance of this Warrant, agrees:
 1.    Number of Shares. Subject to the
terms and conditions hereinafter set forth, including on Exhibit A attached hereto, the Registered Holder is entitled, upon surrender of this Warrant, to purchase from the Company the number of Warrant Shares
(subject to adjustment as provided herein) set forth in Exhibit A attached hereto. 

2.    Exercise. 

a.    Method of Exercise. This Warrant may be exercised by the Registered Holder, in whole or in part, at any
time or from time to time on any day before the Expiration Date, subject to the terms and conditions set forth on Exhibit A attached hereto, by delivering a purchase/exercise form in the form appended hereto as Exhibit
B duly executed by such Registered Holder or by such Registered Holder’s duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may designate, along with a copy of this
Warrant. 

 b.    Payment. Unless the Registered Holder is exercising
this Warrant pursuant to a Net Issue Exercise in the manner specified in Section 2(d), the Registered Holder shall also, as a condition to any exercise of this Warrant, deliver to the Company payment in full for the Purchase Price payable in
respect of the number of Warrant Shares purchased upon such exercise. The Purchase Price may be paid by cash, check or wire transfer. 

c.    Partial Exercise. Upon a partial exercise of this Warrant, this Warrant shall be cancelled and
replaced with a new Warrant (the “Replacement Warrant”) on terms identical to those contained in this Warrant, except that the maximum number of Warrant Shares issuable upon exercise is equal to the maximum number of Warrant Shares
issuable under this Warrant (as set forth above) reduced by (i) the number of Warrant Shares set forth on the purchase/exercise form, or (ii) the number of shares calculated pursuant to Section 2(d), as applicable. 

 

	 	d.	 Net Issue Exercise. 

 

	 	(i)	 In lieu of exercising this Warrant and delivering payment in the manner provided in Section 2(b), the
Registered Holder may elect to exercise all or any portion of this Warrant by net exercise by giving notice of such election on the purchase/exercise form appended hereto as Exhibit B duly executed by such Registered Holder or by such Registered
Holder’s duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may designate, along with a copy of this Warrant, in which event the Company shall issue to such Registered Holder a
number of Warrant Shares computed using the following formula: 

  

							
		 	X=	 	Y (A - B)	  	
		 		 	 A
	  	

 where 
  

	 	X =	 the number of Warrant Shares to be issued to the Registered Holder. 

 

	 	Y =	 the number of Warrant Shares purchasable under this Warrant as set out on the purchase/exercise form.

  

	 	A =	 the fair market value of one Warrant Share on the date of such net exercise. 

 

	 	B =	 the Purchase Price. 

	 	(ii)	 For purposes of this Section 2(d), the “fair market value of Warrant Share on the date of net
exercise” shall mean with respect to each Warrant Share: 

  

	 	(A)	 (a) if the exercise is in connection with consummation of the sale of the securities of the Company (or an
affiliate (as defined in Rule 405 under the Securities Act) thereof) pursuant to a registration statement filed by the Company (or an affiliate thereof) under the Securities Act), in connection with a firm commitment underwritten offering to the
general public (an “IPO”), and if the Company’s registration statement relating to such public offering has been declared effective by the Securities and Exchange Commission, then the fair market value shall be the initial “Price
to Public” per share specified in the final prospectus with respect to the offering, or (b) if this Warrant is exercised following the IPO, then the Fair Market Value shall equal the average of the closing prices of the Company’s
Ordinary Share, as reported on the principal stock exchange on which the Company’s shares are traded at such time for the thirty (30) consecutive trading days immediately preceding the exercise of the Warrant; or (c) if this Warrant
is exercised in connection with a Merger and Acquisition or a Liquidation Event - the price per Warrant Share paid or otherwise distributed in such transaction or other event; 

 

	 	(B)	 if (A) is not applicable, the fair market value of Warrant Share shall be at the per share valuation as
determined by an independent third-party valuation firm within the prior twelve (12) months approved in good faith by the Company’s Board of Directors (the “Board”), unless the Company is at such time subject to a consolidation
or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving entity), or any transfer of all or substantially all of the assets of the Company, in which case the fair market
value of Warrant Share shall be deemed to be the value received by the holders of Ordinary Shares pursuant to such acquisition. 

  

	 	e.	 Issuance of Shares. Upon exercise of the Warrant, and as a condition of such exercise, the
Registered Holder shall become (if not already) party to that certain Third Amended and Restated Investors’ Rights Agreement, dated March 22, 2021, by and among the Company and the other parties named therein, as amended from time to time,
a true and correct copy of which has been provided to the Registered Holder (the “Investors’ Rights Agreement”), by delivering a joinder in the form appended hereto as Exhibit D duly executed by such Registered Holder.
As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within ten (10) business days thereafter, the Company will, at its expense, cause to be issued in the name of, and delivered to, the Registered
Holder: 

 i.    certificate or certificates for the number of Warrant Shares to which
such Registered Holder shall be entitled; 
 ii.    in case such exercise is in part only, a Replacement
Warrant as provided in Section 2(c); and 
 iii.    if applicable, a check payable to the Registered
Holder for any cash amounts payable as described in Section 12. 
  

	 	f.	 Automatic Exercise. If this Warrant remains outstanding as of the Expiration Date then, at such
time, this Warrant shall, automatically and without any action on the part of the Registered Holder, be exercised pursuant to Section 2(d) effective immediately prior to the termination of this Warrant pursuant to Section 8, unless the
Registered Holder shall have earlier provided written notice to the Company that the Registered Holder desires that this Warrant terminate unexercised. If this Warrant is automatically exercised pursuant to this Section 2(f) the Company shall
notify the Registered Holder of such exercise as soon as reasonably practicable. 

  

	 	g.	 Effective Time of Exercise. Each exercise of this Warrant shall be deemed to have been made upon
the satisfaction of all of the conditions set forth herein. At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided herein shall be deemed to have become the
holder or holders of record of the Warrant Shares represented by such certificates. 

  

	 	h.	 Taxes. The issuance of the Warrant, and the Warrant Shares upon the exercise of the Warrant,
shall be made without the deduction or withholding of any taxes, levies, assessments, imposts, duties or similar charges imposed by any taxing authority (“Taxes”), unless otherwise required by law. If such deduction or withholding is so
required, the Company shall pay the amount of such Taxes so imposed to the applicable 

	 	
taxing authority, and shall pay such additional amounts to the Registered Holder so that the Registered Holder receives the net amount after such deduction or withholding that it would have
received had no such deduction or withholding been imposed. 

 3.     Adjustments. 

a.    Share Splits and Dividends. The Purchase Price and the number of Warrant Shares for which this Warrant
remains exercisable shall each be proportionally adjusted to reflect any share dividend, share split, reverse share split or other similar event affecting the number of outstanding Warrant Shares. 

b.    Adjustment for Other Dividends and Distributions. In case the Company shall make or issue, or shall
fix a record date for the determination of eligible holders entitled to receive, a dividend or other distribution payable with respect to the Warrant Shares that is payable in (a) securities of the Company (other than issuances with respect to
which adjustment is made under Section 3(a) or Section 3(c)) or (b) assets (other than cash) which dividend or distribution is actually made (each, a “Dividend Event”), then, and in each such case, Registered Holder,
upon exercise of this Warrant at any time after such Dividend Event, shall receive, in addition to the Warrant Shares, the securities or such other assets of the Company that would have been payable to Registered Holder if Registered Holder had
completed such exercise of this Warrant immediately prior to such Dividend Event. 
 c.    Adjustment for
Reorganization, Consolidation, Merger. In case of any recapitalization or reorganization of the Company or in case the Company shall consolidate with or merge into one or more other corporations or entities which results in a change of the
Warrant Shares (each, a “Reorganization Event”), then, and in each such case, Registered Holder, upon the exercise of this Warrant after such Reorganization Event, shall be entitled to receive, in lieu of the shares or other
securities and property that Registered Holder, would have been entitled to receive upon such exercise prior to such Reorganization Event, the shares or other securities or property which Registered Holder, would have been entitled to receive upon
such Reorganization Event if, immediately prior to such Reorganization Event, Registered Holder, had completed such exercise of this Warrant, all subject to further adjustment as provided in this Warrant. If after such Reorganization Event the
Warrant is exercisable for securities of a corporation or entity other than the Company, then such corporation or entity shall duly execute and deliver to Registered Holder, a supplement hereto acknowledging such corporation’s or other
entity’s obligations under this Warrant, and in each such case the terms of this Warrant shall be applicable to the shares or other securities or property receivable upon the exercise of this Warrant after the consummation of such
Reorganization Event. 
 d.    No Change Necessary. The form of this Warrant need not be changed because
of any adjustment in the Purchase Price or in the number of Warrant Shares issuable upon its exercise. 

e.    Notice. The Company shall provide prompt notice to the Registered Holder, using commercially
reasonable efforts to provide such notice at least 5 business days in advance, of any adjustment made pursuant to this Section 3; provided that, for notice in connection with a Reorganization Event, if providing such notice would cause the
Company to violate any contractual or other restrictions that the Company is then subject to with respect to confidentiality of a particular transaction or otherwise, the Company shall only be required to provide to the Registered Holder such form
of notice and upon such timing that the Company is required to provide to holders of shares of the same series and class of shares as the Warrant Shares. The Company will also provide information requested by Registered Holder that is reasonably
necessary to enable Registered Holder to comply with Registered Holder’s accounting or reporting requirements.

4.    Transfers. 

a.    Unregistered Security. Each holder of this Warrant acknowledges that, as of the date hereof, none of
the Company’s securities (including this Warrant and the Warrant Shares) have been registered under the Securities Act, and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant
Shares issued upon its exercise (or any securities issued by the Company upon conversion or exchange thereof) in the absence of (i) an effective registration statement under the Securities Act as to the sale of any such securities and
registration or qualification of such securities under any applicable U.S. federal or state securities law then in effect, or (ii) an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required.
Each certificate or other instrument for Warrant Shares issued upon the exercise of this Warrant (and any securities issued by the Company upon conversion or exchange thereof) shall bear a legend substantially to the foregoing effect. The Warrant
Shares issuable pursuant to this Warrant shall have the registration rights described in Section 7 hereto. 

 b.    Transferability. Subject to the provisions of
Section 4(a) hereof, this Warrant may be transferred and assigned and all rights hereunder are transferable, in whole or in part, to an affiliate (as defined in Rule 405 under the Securities Act) of the Registered Holder upon surrender of this
Warrant with a properly executed assignment (in the form of Exhibit C hereto) at the principal office of the Company and subject to the provisions of Section 4.a. hereof. 

c.    Warrant Register. The Company will maintain a register containing the names and addresses of the
Registered Holder(s) of this Warrant. Until any transfer of this Warrant is made in the warrant register, the Company may treat the Registered Holder of this Warrant as the absolute owner hereof for all purposes. Any Registered Holder may change
such Registered Holder’s address as shown on the warrant register by written notice to the Company requesting such change.

warrants to the Company that: 
 a.    Authorization. The Registered Holder has full power and authority

c.    Restricted Securities. The Registered Holder understands that the Securities have not been, and, other

of the investment intent and the accuracy of the Registered Holder’s representations as expressed herein. The Registered Holder understands that unless and until registered the Securities are “restricted securities” under applicable
U.S. federal and state securities laws and that, pursuant to these laws, the Registered Holder must hold the Securities indefinitely unless they are registered with the Securities and Exchange Commission and, if applicable, qualified by state
authorities, or an exemption from such registration and qualification requirements is available. The Registered Holder understands that no public market now exists for any of the securities issued by the Company, and that the Company has made no
assurances that a public market will ever exist for the Securities. 
 d.    Accredited Investor. The
Registered Holder is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

performance, injunctive relief or other equitable remedies.

and consultants of the Company pursuant to its equity compensation plans which have been duly adopted by the Company’s Board of Directors (the “Board”) and approved by the Company’s shareholders (collectively, the
“Incentive Plans”). Of such reserved Ordinary Shares, 12,613,200 Ordinary Shares underline outstanding options. 

iii.    Except (A) for conversion privileges of the Company’s preferred shares, warrants to

transfer under state and/or federal securities laws and the Company’s amended and restated articles of association, as may be amended from time to time (the “Articles”), including the Public Company Articles (as defined below).

 e.    Offering. Subject in part to the truth and accuracy of the Registered Holder’s
representations set forth in Section 5 hereof, the offer, issuance and sale of this Warrant is, and the issuance of the Warrant Shares upon exercise of this Warrant (and the issuance of any securities issuable by the Company upon conversion or
exchange thereof) will be, exempt from the registration requirements of the Securities Act, and are exempt from the qualification requirements of any applicable state securities laws; and neither the Company nor anyone acting on its behalf will take
any action hereafter that would cause the loss of such exemptions. 
 f.    Charter Documents. The Company
has provided the Registered Holder true and complete copies of (A) the Articles effective as of the Original Issuance Date and (B) the amended and restated articles of association that have been adopted by the Company’s shareholders
and that will become effective immediately prior to, and contingent upon, the consummation of the Contemplated IPO (the “Public Company Articles”). The Company shall not by amendment of the Articles or the Public Company Articles or
through a reorganization, transfer or sale of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed
under this Warrant, but shall at all times 
  

 
in good faith reasonably assist in carrying out of all the provisions of this Warrant and in taking all such action as may be reasonably necessary or appropriate to protect the rights of the
Registered Holder under this Warrant against impairment. However, the Company shall not be deemed to have impaired the rights of the Registered Holder (i) if the Articles or the Public Company Articles are amended or waived in a manner that
does not (individually or when considered in the context of any other actions being taken in connection with such amendments or waivers) affect the Registered Holder in a manner different from the effect that such amendments or waivers have on the
rights of other holders of the same series and class as the Warrant Shares or (ii) in connection with the adoption and the effectiveness of the Public Company Articles; provided, however, that, notwithstanding the foregoing, the Company shall
not impose any restrictions on the transferability or alienability of the Warrant Shares other than (x) as may be in effect as of the Original Issuance Date or (y) contemplated under the Public Company Articles, in each case, without the
written consent of the Registered Holder. 
 g.    Financial and Other Reports. Until the consummation of

discretion) with regulatory, accounting and reporting requirements applicable to the Registered Holder, (i) within 180 days after the close of each fiscal year of the Company, audited financial statements of the Company and the notes thereto
including a balance sheet, together with an income statement and a cash flow statement, for such fiscal year; and (ii) promptly after the closing of each equity financing consummated by the Company after the Original Issuance Date, a
post-closing summary capitalization table and other information relating to the then-current valuation of the Company including any 409A valuation (or equivalent) reports, provided, however, that the Company shall not be
obligated to furnish a capitalization table or valuation following the repurchase of the Ordinary Shares from former employees, directors or consultants (the “Repurchased Shares”) and the subsequent resale of all or part of the
Repurchased Shares if the Repurchased Shares represent less than 5% of the issued and outstanding Ordinary Shares, on a fully-diluted basis, at the time of repurchase, and (iii) at any time and from time to time, such information as the
Registered Holder may reasonably request ((i) through (iii) collectively the “Information Rights”). Any such information provided to the Registered Holder pursuant to the Information Rights shall be used by the Registered
Holder solely for such regulatory, accounting and reporting requirements. Notwithstanding anything in this Section 6(g) to the contrary, if in connection with a Merger and Acquisition (as defined below) the Registered Holder receives
securities of a privately held company, then the Company shall use commercially reasonable efforts to cause the Information Rights described in this Section 6(g) to be deemed to continue to apply to such company. 

7.    Registration Rights. 

The Warrant Shares issuable pursuant to this Warrant shall have registration rights as set forth in Section 1 of the
Investors’ Rights Agreement and shall be Registrable Securities as defined therein. The provisions set forth in the Investors’ Rights Agreement relating to such registration rights in effect as of Original Issuance Date may not be amended,
modified or waived by the Company without the prior written consent of the Registered Holder unless such amendment, modification or waiver affects the rights under the Investors’ Rights Agreement associated with the Warrant Shares in the same
manner as such amendment, modification, or waiver affects the rights under the Investors’ Rights Agreement associated with all other shares of the same series and class of Warrant Shares.

8.    Termination. This Warrant (and the right to purchase securities upon exercise hereof) shall terminate
upon the earliest to occur of the following (the “Expiration Date”): 
 a.    the tenth (10th)
anniversary of the Original Issuance Date, or 
 b.    immediately prior to the consummation of a Merger and Acquisition
or a Liquidation Event (as defined in the Company’s Articles), or 
 c.    immediately prior to the consummation of
an IPO (other than the Contemplated IPO) (a “New IPO”), 
 provided that the Registered Holder shall be given reasonable notice of such
Merger and Acquisition, Liquidation Event or New IPO (and the Company shall use commercially reasonable efforts to provide such notice at least 5 business days in advance of the consummation of the Merger and Acquisition, Liquidation Event or New
IPO) and the opportunity to exercise this Warrant prior to or concurrently with the consummation of such Merger and Acquisition, Liquidation Event or New IPO. 

 9.    Notices of Certain Transactions. In case: 

a.    the Company shall take a record of the holders of its outstanding shares of the same class as the Warrant Shares (or
other shares or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of any
class or any other securities, or to receive any other right, or 
 b.    of any capital reorganization of the Company,
any reclassification of the share capital of the Company, any consolidation or merger of the Company, any Merger and Acquisition, any Liquidation Event, or any New IPO

then, and in each such case, the Company will mail or cause to be mailed to the Registered Holder of this Warrant a notice specifying, as the case may be,
(i) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up, redemption or conversion is to take place, and the time, if any is to be fixed, as of which the holders of record of the
Company’s outstanding shares of the same class as the Warrant Shares (or such other shares or securities at the time deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation, winding--up, redemption or conversion) are to be determined. Such notice shall be mailed at least 5 business days prior to the record date or effective date for the event specified in such notice. In addition, the
Company shall use commercially reasonable efforts to provide the Registered Holder with prompt written notice of any amendment to the term “Merger and Acquisition” set forth in the Articles, other than in connection with the adoption and
effectiveness if the Public Company Articles. Notwithstanding anything to the contrary set forth in this Section 9, if providing any contemplated notice would cause the Company to violate any contractual or other restrictions that the Company
is subject to with respect to confidentiality of a particular transaction or otherwise, the Company shall only be required to provide to the Registered Holder such form of notice and upon such timing that the Company is required to provide to
holders of shares of the same series and class as the Warrant Shares. 
 10.    Replacement of Warrants.
Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement (with surety if reasonably
required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor. 

11.    No Rights as Shareholder. Until and to the extent of the exercise of this Warrant, the Registered
Holder of this Warrant shall not have or exercise any rights by virtue hereof as a shareholder of the Company. 

12.    No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise
hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the fair market value of one Warrant Share on the date of exercise, as determined in
accordance with Section 2(d)(ii).

Indenture Supplement. This Base Indenture, as it may be supplemented, including by each Indenture Supplement, is a security agreement
within the meaning of the UCC.

 

The Indenture Trustee acknowledges
the Grant of such Security Interest, and agrees to perform the duties herein in accordance with the terms hereof.

 

Notwithstanding
anything to the contrary in this Base Indenture or any of the other Transaction Documents, the security interest of the Indenture
Trustee for the benefit of the Noteholders created hereby with respect to the Participation Certificates and the MSRs is subject to the
following provisions, which provisions shall be included in each financing statement filed in respect hereof:

 

The Security Interest
described in this financing statement is subordinate to all rights of Fannie Mae under (i) the terms of an Acknowledgment Agreement,
with respect to the Security Interest (as defined therein) among Fannie Mae, PennyMac Loan Services, LLC and Citibank, N.A., solely as
Indenture Trustee under the Base Indenture, dated April 28, 2021, and not in its individual capacity (ii) the terms of a Subordination
of Interest Agreement, with respect to the Security Interest (as defined therein), among Fannie Mae and the Servicer, and (iii) the
Mortgage Selling and Servicing Contract, the Fannie Mae Selling Guide, the Fannie Mae Servicing Guide and all supplemental servicing instructions
or directives provided by Fannie Mae, all applicable master agreements, recourse agreements, repurchase agreements, indemnification agreements,
loss-sharing agreements, and any other agreements between Fannie Mae and the Servicer, and all as amended, restated or supplemented from
time to time (collectively, the “Fannie Mae Lender Contract”), which rights include the right of Fannie Mae
to terminate the Fannie Mae Lender Contract with or without cause and the right to sell, or have transferred, the Servicing Rights.

 

    	 	3	 

     

    

 

The Issuer hereby authorizes
the Administrator, on behalf of the Issuer and the Indenture Trustee, and its assignees, successors and designees to file one or more
UCC financing statements, financing statement amendments and continuation statements to perfect the security interest granted above. In
addition, the Issuer hereby consents to the filing of a financing statement describing the Collateral covered thereby as “all assets
of the Debtor, now owned or hereafter acquired,” or such similar language as the Administrator, on behalf of the Indenture Trustee,
and its assignees, successors and designees may deem appropriate.

 

Subject to the interests and
rights of Fannie Mae as set forth in this Base Indenture and in the Acknowledgment Agreement and the Fannie Mae Requirements, the parties
hereto intend that the Security Interest Granted under this Base Indenture shall give the Indenture Trustee on behalf of the Secured Parties
a first priority perfected security interest in, to and under the Collateral, and all other property described in this Base Indenture
as a part of the Trust Estate and all proceeds of any of the foregoing in order to secure the obligations of the Issuer to the Indenture
Trustee and the Noteholders under the Notes, this Base Indenture, the related Indenture Supplement, and all of the other Transaction Documents.
The Indenture Trustee on behalf of the Secured Parties shall have all the rights, powers and privileges of a secured party under the UCC.
The Issuer agrees to execute and file all filings (including filings under the UCC) and take all other actions reasonably necessary in
any jurisdiction to provide third parties with notice of the Security Interest Granted pursuant to this Base Indenture and to perfect
such Security Interest under the UCC.

Any such certificate or opinion of, or representation by, counsel may be based, insofar as it relates to factual matters, upon a certificate
or opinion of, or representations by, the Issuer stating that the information with respect to such factual matters is in the possession

    	 	6	 

     

    

 

Where any Person is required
to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this
Base Indenture, they may, but need not, be consolidated and form one instrument.

 

		Section 1.5.	Acts of Noteholders.

 

(a)          Any
request, demand, authorization, direction, notice, consent, waiver or other action (each, an “Action”) provided
by this Base Indenture to be given or taken by Noteholders of any Class may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Noteholders in person or by an agent duly appointed in writing. Except as herein otherwise
expressly provided, such Action will become effective when such instrument or instruments are delivered to the Indenture Trustee, and,
where it is hereby expressly required, to the Issuer. Such instrument or instruments and any such record (and the Action embodied therein
and evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing such instrument
or instruments and so voting at any meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or the
holding by any Person of a Note, will be sufficient for any purpose of this Base Indenture and (subject to Section 11.1) conclusive
in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 1.5.

 

(b)          The
fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness to such execution
or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by an officer of a corporation or
a member of a partnership, on behalf of such corporation or partnership, such certificate or affidavit will also constitute sufficient
proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the person executing
the same, may also be proved in any other manner which the Indenture Trustee deems sufficient.

 

(c)          The
ownership of Notes will be proved by the Note Register.

 

(d)          Any
Action by a Noteholder will bind all subsequent Noteholders of such Noteholder’s Note, in respect of anything done or suffered to
be done by the Indenture Trustee or the Issuer in reliance thereon whether or not notation of such Action is made upon such Note.

 

(e)          Without
limiting the foregoing, a Noteholder entitled hereunder to take any Action hereunder with regard to any particular Note may do so with
regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant
to such appointment with regard to all or any part of such principal amount. Any notice given or Action taken by a Noteholder or its agents
with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by
separate Noteholders of each such different part.

 

    	 	7	 

     

    

 

(f)           Without
limiting the generality of the foregoing, unless otherwise specified pursuant to one or more Indenture Supplements, a Noteholder, including
a Depository that is the Noteholder of a Global Note representing Book-Entry Notes, may make, give or take, by a proxy or proxies duly
appointed in writing, any Action provided in this Base Indenture to be made, given or taken by a Noteholder, and a Depository that is
the Noteholder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in or security entitlements to
any such Global Note through such Depository’s standing instructions and customary practices.

 

(g)          The
Issuer may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in or security entitlements
to any Global Note held by a Depository entitled under the procedures of such Depository to make, give or take, by a proxy or proxies
duly appointed in writing, any Action provided in this Base Indenture to be made, given or taken by Noteholders. If such a record date
is fixed, the Noteholders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make,
give or take such Action, whether or not such Noteholders remain Noteholders after such record date. No such Action shall be valid or
effective if made, given or taken more than ninety (90) days after such record date.

 

		Section 1.6.	Notices, etc., to Indenture Trustee, Issuer, Administrator,
the Administrative Agent and Note Rating Agencies.

 

(a)          Any
Action of Noteholders or other document provided or permitted by this Base Indenture to be made upon, given or furnished to, or filed
with, the Indenture Trustee by any Noteholder or by the Issuer will be sufficient for every purpose hereunder if in writing (which shall
include electronic transmission) and personally delivered, express couriered, electronically transmitted or mailed by registered or certified
mail to the Indenture Trustee (or the bank serving as Indenture Trustee in any of its capacities) at its Corporate Trust Office, or the
Issuer or the Administrator by the Indenture Trustee or by any Noteholder will be sufficient for every purpose hereunder (except with
respect to notices to the Indenture Trustee of an Event of Default as provided in Section 8.1) if in writing (which shall
include electronic transmission) and personally delivered, express couriered, electronically transmitted or mailed by registered or certified
mail, addressed to it at: (i) in the case of the Indenture Trustee, in any of its capacities (except in its capacity as Note Registrar

    	 	8	 

     

    

 

(b)          Where
this Base Indenture provides for notice to or consent from any Note Rating Agency, such notice or consent will only be required to the
extent that any Outstanding Class is then currently being rated at the request of PLS, and as specified in the related Indenture
Supplement, and if no Outstanding Class is being so rated, including in the event ratings unsolicited by PLS are being issued, such
notice or consent provisions shall be of no force or effect. In the event that an Indenture Supplement provides that one or more Classes
obtain a rating, any notice shall be sufficient for every purpose hereunder (except with respect to notices to the Indenture Trustee of
an Event of Default as provided in Section 3.3 or Section 8.1) if in writing (which shall include electronic transmission)
and personally delivered, express couriered, electronically transmitted or mailed by registered or certified mail, addressed to it at
the address set forth in the related Indenture Supplement. Failure to give such notice will not affect any other rights or obligations
created hereunder and will not under any circumstance constitute an Adverse Effect.

 

		Section 1.7.	Notices to Noteholders; Waiver.

 

(a)          Where
this Base Indenture, any Indenture Supplement or any Note provides for notice to registered Noteholders of any event, such notice will
be sufficiently given (unless expressly provided otherwise herein, in such Indenture Supplement or in such Note) if in writing and mailed
by overnight courier, sent by facsimile, sent by electronic transmission or personally delivered to each Noteholder of a Note affected
by such event, at such Noteholder’s address as it appears in the Note Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, facsimile,
electronic transmission or delivery, none of the failure to mail, send by facsimile, send by electronic transmission or deliver such notice,
or any defect in any notice so mailed, to any particular Noteholders will affect the sufficiency of such notice with respect to other
Noteholders and any notice that is mailed, sent by facsimile, sent by electronic transmission or delivered in the manner herein provided
shall conclusively have been presumed to have been duly given.

 

Where this Base Indenture,
any Indenture Supplement or any Note provides for notice in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver will be the equivalent of such notice. Waivers of notice by Noteholders
will be filed with the Indenture Trustee, but such filing will not be a condition precedent to the validity of any action taken in reliance
upon such waiver.

 

(b)          In
case, by reason of the suspension of regular mail service as a result of a strike, work stoppage, acts of war or terrorism, civil or military
disturbances, pandemics, epidemics, government-mandated closures, hurricanes, tornadoes, earthquakes, floods, fires or other natural disasters,
or other acts of God, it will be impractical to mail notice of any event to any Noteholder of a Note when such notice is required to be
given pursuant to any provision of this Base Indenture, then any method of notification as will be satisfactory to the Indenture Trustee
and the Issuer will be deemed to be a sufficient giving of such notice.

 

(c)          The
Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary each agree to accept and act upon instructions or directions
pursuant to this Base Indenture or any document executed in connection herewith sent by unsecured email, facsimile transmission or other
similar unsecured electronic methods; provided, however, that the Indenture Trustee shall have received an incumbency certificate
(attached hereto as Exhibits C-1 through C-4) listing such person as a person designated to provide such instructions or
directions, which incumbency certificate may be amended whenever a person is added or deleted from the listing. If such person elects
to give the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary email or facsimile instructions (or instructions
by a similar electronic method) and the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary in its discretion
elects to act upon such instructions, the Indenture Trustee’s, Calculation Agent’s, Paying Agent’s and Securities Intermediary’s
reasonable understanding of such instructions, as applicable, shall be deemed controlling.

 

    	 	9	 

     

    

 

(d)          None
of the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary shall be liable for any losses, costs or expenses
arising directly or indirectly from the Indenture Trustee’s reliance upon and compliance with such instructions notwithstanding
such instructions conflicting with or being inconsistent with a prior written instruction except as a result of their respective willful
misconduct, negligence or bad faith. Any Person providing such instructions or directions agrees to assume all risks arising out of the
use of such electronic methods to submit instructions and directions to the Indenture Trustee, Calculation Agent, Paying Agent and Securities
Intermediary, including the risk of Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary acting on unauthorized
instructions, and the risk of interception and misuse by third parties and acknowledges and agrees that there may be more secure methods
of transmitting such instructions than the method(s) selected by it and agrees that the security procedures (if any) to be followed
in connection with its transmission of such instructions provide to it a commercially reasonable degree of protection in light of its
particular needs and circumstances.

 

		Section 1.8.	Administrative Agent.

 

(a)          Discretion
of Administrative Agent. Any provision providing for the exercise of discretion of the Administrative Agent means that such discretion
may be executed in the reasonable discretion of the Administrative Agent. In addition, as further provided in the definition of “Administrative
Agent” herein and notwithstanding any other provision in this Base Indenture to the contrary, any approvals, consents, votes or
other rights exercisable by the Administrative Agent under this Base Indenture (other than any Indenture Supplement related to a specific
Series) shall require the approval, consent, vote or other exercise of rights of each Person specified by name under the definition of
 “Administrative Agent” or in its stead its Affiliate or successor as noticed to the Indenture Trustee, unless otherwise specified
in any Indenture Supplement related to a specific Series.

 

(b)          Nature
of Duties. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Base Indenture,
a related Indenture Supplement or in the other Transaction Documents. The Administrative Agent shall not have by reason of this Base Indenture
or any Transaction Document a fiduciary relationship in respect of any Noteholder. Nothing in this Base Indenture or any of the Transaction
Documents, express or implied, is intended to or shall be construed to impose upon the Administrative Agent any obligations in respect
of this Base Indenture or any of the other Transaction Documents except as expressly set forth herein or therein. Each Noteholder shall
make its own independent investigation of the financial condition and affairs of the Issuer in connection with the purchase of any Note
and shall make its own appraisal of the creditworthiness of the Issuer and the value of the Collateral, and the Administrative Agent shall
have no duty or responsibility, either initially or on a continuing basis, to provide any Noteholder with any credit or other information
with respect thereto, whether coming into its possession before the Closing Date, as applicable, or at any time or times thereafter.

 

    	 	10	 

     

    

 

(c)          Rights,
Exculpation, Etc. The Administrative Agent and its directors, officers, agents or employees shall not be liable for any action taken
or omitted to be taken by it under or in connection with this Base Indenture or the other Transaction Documents. Without limiting the
generality of the foregoing, the Administrative Agent: (i) may consult with legal counsel (including counsel to the Administrative
Agent or counsel to the Issuer), independent public accountants, and other experts selected by it and shall not be liable for any action
taken or omitted to be taken in good faith by it in accordance with the advice of such counsel or experts; (ii) makes no warranty
or representation to any Noteholder and shall not be responsible to any Noteholder for any statements, certificates, warranties or representations
made in or in connection with this Base Indenture or the other Transaction Documents; (iii) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Base Indenture or the other Transaction
Documents on the part of any Person, the existence or possible existence of any default or Event of Default, or to inspect the Collateral
or other property (including the books and records) of any Person; (iv) shall not be responsible to any Noteholder for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of this Base Indenture or the other Transaction Documents or any
other instrument or document furnished pursuant hereto or thereto; and (v) shall not be deemed to have made any representation or
warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Indenture Trustee’s
Adverse Claim thereon, or any certificate prepared by the Issuer in connection therewith, nor shall the Administrative Agent be responsible
or liable to the Noteholders for any failure to monitor or maintain any portion of the Collateral. Without limiting the foregoing and
notwithstanding any understanding to the contrary, no Noteholder shall have any right of action whatsoever against the Administrative
Agent as a result of the Administrative Agent acting or refraining from acting under this Base Indenture, the Notes or any of the other
Transaction Documents in its own interests as a Noteholder or otherwise.

 

(d)          Reliance.
The Administrative Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any
telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and
with respect to all matters pertaining to this Base Indenture or any of the other Transaction Documents and its duties hereunder or thereunder,
upon advice of counsel selected by it.

All covenants and agreements
in this Base Indenture by the Issuer will bind its successors and assigns, whether so expressed or not. All covenants and agreements of
the Indenture Trustee in this Base Indenture shall bind its successors, co-trustees and agents of the Indenture Trustee.

 

		Section 1.11.	Severability of Provisions.

 

In case any provision in this
Base Indenture or in the Notes will be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions
will not in any way be affected or impaired thereby.

 

		Section 1.12.	Benefits of Indenture.

Agent or Paying Agent, the Note Registrar, the Securities Intermediary, the Calculation Agent, any Secured Party and the Noteholders of
Notes (or such of them as may be affected thereby), any benefit or any legal or equitable right, remedy or claim under this Base Indenture.

BASE INDENTURE AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO OR IN CONNECTION WITH THIS BASE INDENTURE, THE RELATIONSHIP
OF THE PARTIES HERETO, AND/OR THE INTERPRETATION AND ENFORCEMENT OF THE RIGHTS AND DUTIES OF THE PARTIES HERETO WILL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT REFERENCE TO THE CONFLICT OF LAW PRINCIPLES THEREOF OTHER THAN SECTIONS
5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

 

THE SECURITIES INTERMEDIARY,
THE ADMINISTRATOR AND THE ISSUER AGREE THAT THEY WILL NOT CHANGE THE APPLICABLE LAW IN FORCE WITH RESPECT TO ISSUES REFERRED TO IN ARTICLE 2(1) OF
THE HAGUE SECURITIES CONVENTION TO A STATE OTHER THAN THE STATE OF NEW YORK.

 

		Section 1.14.	Counterparts; Electronic and Facsimile Execution.

 

This Base Indenture may be
executed in counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall
constitute one and the same instrument. The words “executed,” “signed,” “signature,” and words of
like import as used above and elsewhere in this Base Indenture or in any other certificate, agreement or document related to this transaction
shall include, in addition to manually executed signatures, images of manually executed signatures transmitted by facsimile or other electronic
format (including, without limitation, “pdf,” “tif” or “jpg”) and other electronic signatures (including,
without limitation, any electronic sound, symbol, or process, attached to or logically associated with a contract or other record and
executed or adopted by a person with the intent to sign the record). The use of electronic signatures and electronic records (including,
without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall
be of the same legal effect, validity, enforceability and admissibility as a manually executed signature or use of a paper-based record-keeping
system to the fullest extent permitted by applicable law, including the federal Electronic Signatures in Global and National Commerce
Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law
based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. Delivery of an executed counterpart of a signature page to
this Base Indenture by facsimile or other electronic means shall be effective as delivery of a manually executed counterpart of this Base
Indenture. Each party to this Base Indenture hereby consents to the use of any secure third party electronic signature capture service
providers (including, without limitation, DocuSign), as long as such service providers use system logs and audit trails that establish

the reasonable request of the Administrative Agent, shall prepare and forward for filing, or shall cause to be forwarded for filing, all
filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect and maintain the first

and all other documents that the Issuer, the Servicer or PLS, as the case may be, shall keep on file, in accordance with its customary

    	 	16	 

     

    

 

		(c)	Delivery of Updated Participation
Certificate Schedule and Eligible Securities Schedule.

 

(i)          The
Administrator shall deliver to the Indenture Trustee an updated Participation Certificate Schedule prior to the addition, modification
or deletion of any Participation Certificate as Collateral and the Indenture Trustee shall hold the most recently delivered version as
the definitive Participation Certificate Schedule. The Administrator represents and warrants, as of the date hereof and as of the date

Administrator shall deliver to the Indenture Trustee an updated schedule of Eligible Securities prior to the addition, modification or
deletion of any Eligible Security as Collateral and the Indenture Trustee shall hold the most recently delivered version as the definitive

that the schedule of Eligible Securities, as it may be updated by the Administrator from time to time and delivered to the Indenture Trustee,
is a true, complete and accurate list of all Eligible Securities.

 

(d)          Marking
of Records. The Administrator shall ensure that, from and after the time of the sale or contribution of the Participation Certificates
to the Issuer under the PC Repurchase Agreement and the Grant thereof to the Indenture Trustee pursuant to this Base Indenture, any records
(including any computer records and back-up archives) maintained by or on behalf of the Servicer that refer to any Participation Certificate
indicate clearly the interest of the Issuer and the Security Interest of the Indenture Trustee in such Participation Certificate and that
such Participation Certificate is owned by the Issuer and subject to the Indenture Trustee’s Security Interest. Indication of the
Issuer’s ownership of a Participation Certificate and the Security Interest of the Indenture Trustee shall be deleted from or modified
on such records when, and only when, such Participation Certificate has been paid in full, repurchased, or assigned by the Issuer and
released by the Indenture Trustee from its Security Interest.

 

(e)          Custodian.
PLS, as Repo Seller, the Issuer and the Administrative Agent each confirm, and each Noteholder is deemed to confirm, that it is treating
Citibank, in its capacity as a Custodian, as holding each original Participation Certificate as a “custodian” on behalf of
the Issuer as a “customer” in connection with a “securities contract” (as each such term is used in Section 101(22)
of the Bankruptcy Code), and each such Person confirms (or is deemed to confirm, in the case of the Noteholders) that in such capacity
Citibank is serving as a “financial institution” (as defined in Section 101(22) of the Bankruptcy Code). Citibank confirms
that it is a “commercial bank” (as such term is used in such Section 101(22)) and acknowledges such treatment by such
Persons.

		Section 2.3.	Duties of Custodian with Respect to the Asset Files.

 

(a)          Safekeeping.
The Indenture Trustee or the Administrator, in its capacity as custodian (each, a “Custodian”) pursuant to Section 2.2(b),
shall hold the portion of the Asset Files that it is required to maintain under Section 2.2 in its possession from time to
time for the use and benefit of all present and future Noteholders, and maintain such accurate and complete accounts, records and computer
systems pertaining to each Asset File as shall enable the Calculation Agent and the Indenture Trustee to comply with this Base Indenture.
Each Custodian shall promptly report to the Issuer any failure on its part to hold the Asset Files and maintain its accounts, records
and computer systems as herein provided and promptly take appropriate action to remedy any such failure. The Indenture Trustee shall have
no responsibility or liability for any actions or omissions of the Administrator in its capacity as Custodian or otherwise.

 

(b)          Maintenance
of and Access to Records. Each Custodian shall maintain each portion of the Asset File that it is required to maintain under this

CA 91361 (in the case of the Servicer) as the case may be, or at such other office as shall be specified to the Indenture Trustee and
the Issuer by thirty (30) days’ prior written notice. The Administrator shall take all actions necessary, or reasonably requested
by the Administrative Agent, the Majority Noteholders of all Outstanding Notes or the Indenture Trustee, to amend any existing financing
statements and continuation statements, and file additional financing statements to further perfect or evidence the rights, claims or
security interests of the Indenture Trustee under any of the Transaction Documents (including the rights, claims or security interests
of the Issuer under the PC Repurchase Agreement which have been assigned to the Indenture Trustee). The Indenture Trustee and the Administrator,
in their capacities as Custodian(s), shall make available to the Issuer, the Calculation Agent, the Administrative Agent, any group of
Interested Noteholders and the Indenture Trustee (in the case of the Administrator) or their duly authorized representatives, attorneys
or auditors the portion of the Asset Files that it is required to maintain under this Base Indenture and the accounts, books and records
maintained by the Indenture Trustee or the Administrator with respect thereto as promptly as reasonably practicable following not less
than two (2) Business Days’ prior written notice for examination during normal business hours and in a manner that does not
unreasonably interfere with such Person’s ordinary conduct of business.

 

Neither a Custodian nor any
of its directors, officers or employees shall be liable to anyone for any error of judgment, or for any act done or step taken or omitted
to be taken by it (or any of its directors, officers of employees), or for any mistake of fact or law, or for anything which it may do
or refrain from doing in connection herewith, unless such action constitutes gross negligence, willful misconduct or bad faith of such
Custodian. Knowledge or information acquired by Citibank in its capacity as Custodian hereunder shall not be imputed to Citibank in any
other capacity in which it may act hereunder or to any affiliate of Citibank and vice versa. The Custodian shall be deemed to have the
same rights, immunities and protections as the Indenture Trustee hereunder, except that the Custodian shall not be subject to a prudent
person standard under any circumstances.

a report (the “Administrator’s Calculation Report”) containing the detailed information described in this
Section 3.1(a) and pursuant to Section 3.2(b).

 

By 2:00 p.m. New York
City time on each Payment Date (or such other time as may be agreed to from time to time by the Servicer, the Administrator, the Indenture
Trustee and the Administrative Agent), based upon the Administrator’s Calculation Report and any additional information provided

the Full Amortization Period is in effect, the Series Available Funds for each Series for the upcoming Payment Date;

Class of VFNs Outstanding in respect of such Funding Amount, and the portion of such Funding Amount that is to be paid using Available
Funds pursuant to Section 4.5(a)(1)(viii);

    	 	19

SDQ Rate provided by Fannie Mae for such quarter to the extent available from Fannie Mae.

 

The Calculation Agent does
not receive any loan data or financial information independent from what is supplied to it by the Administrator. Thus, any components
of the calculations or verifications to be performed by the Calculation Agent that require loan data information, including pool balance,
SDQ balance, and non-SDQ loan balances, as well as any financial statement data (including any PIPs), are taken as provided by the Administrator
without verification or recalculation.

(b)          Termination
of Calculation Agent. The Issuer (with the consent of the Majority Noteholders for each Series) may at any time terminate the Calculation
Agent without cause upon sixty (60) days’ prior notice. If at any time the Calculation Agent shall fail to resign after written
request therefor as set forth in this Section 3.1(b), or if at any time the Calculation Agent shall be legally unable to act,
or shall be adjudged bankrupt or insolvent, or a receiver of the Calculation Agent or of its property shall be appointed, or if any public
officer shall take charge or Control of the Calculation Agent or of its property or affairs for the purpose of rehabilitation, conservation
or liquidation, then the Majority Noteholders of all Outstanding Notes may remove the Calculation Agent and if the same entity serves

as provided in Section 11.9(c). If the Calculation Agent resigns or is removed under the authority of the immediately preceding
sentence, then a successor Calculation Agent shall be appointed pursuant to Section 11.9. The Issuer shall give each Note
Rating Agency and the Noteholders notice of any such resignation or removal of the Calculation Agent and appointment and acceptance of

effective until the resignation, removal or termination of the predecessor Calculation Agent and until the acceptance of appointment by
the successor Calculation Agent as provided herein. Any successor Indenture Trustee appointed shall also be the successor Calculation
Agent hereunder, if the predecessor Indenture Trustee served as Calculation Agent and no separate Calculation Agent is appointed. Notwithstanding
anything to the contrary herein, the Indenture Trustee may not resign as Calculation Agent unless it also resigns as Indenture Trustee
pursuant to Section 11.9(b).

 

(c)          Successor
Calculation Agents. Any successor Calculation Agent appointed hereunder shall execute, acknowledge and deliver to the Issuer and to
its predecessor Calculation Agent an instrument accepting such appointment under this Base Indenture, and thereupon the resignation or
removal of the predecessor Calculation Agent shall become effective and such successor Calculation Agent, without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Base Indenture,
with like effect as if originally named as Calculation Agent. The predecessor Calculation Agent shall deliver to the successor Calculation
Agent all documents and statements held by it under this Base Indenture. The Issuer and the predecessor Calculation Agent shall execute
and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in
the successor Calculation Agent all such rights, powers, duties and obligations. Upon acceptance of appointment by a successor Calculation
Agent as provided in this Section 3.1, the Issuer shall mail notice of the succession of such successor Calculation Agent
under this Base Indenture to all Noteholders at their addresses as shown in the Note Register and shall give notice by mail to each applicable
Note Rating Agency. If the Issuer fails to mail such notice within ten (10) days after acceptance of appointment by the successor
Calculation Agent, the successor Calculation Agent shall cause such notice to be mailed at the expense of the Administrator.

toward Funding Amounts or to pay principal on any applicable Notes on the upcoming Payment Date or Interim Payment Date. If the Administrator
supplies no information to the Indenture Trustee in its Determination Date Report concerning Funding Amounts or payments on any Variable
Funding Note in respect of an Interim Payment Date, then the Indenture Trustee shall apply no Available Funds to pay Funding Amounts or
to make payment on any Note on such Interim Payment Date, unless an Event of Default has occurred and is continuing, in which case the
Indenture Trustee shall apply the Available Funds pursuant to Section 4.5(a)(ii).

		(a)	Access to Information.

 

Notwithstanding anything to
the contrary contained in this Section 3.4, Section 2.3, or in any other Section hereof, the Servicer, on
reasonable prior written notice (of not less than five (5) Business Days), shall permit the Administrative Agent, the Indenture Trustee,
the MSR Valuation Agent or any agent or independent certified public accountants selected by the Indenture Trustee, during the Servicer’s
normal business hours, and in a manner that does not unreasonably interfere with the Servicer’s conduct of its regular business,
to examine all the books of account, records, reports and other papers of the Servicer relating to the Portfolio Mortgage Loans, Fannie
Mae Lender Contract and the Participation Certificates, to make copies and extracts therefrom, and to discuss the Servicer’s affairs,
finances and accounts relating to the Portfolio Mortgage Loans, Fannie Mae Lender Contract and the Participation Certificates with the
Servicer’s officers and employees, all at such times and as often as reasonably may be requested; provided that any such Person
seeking access to any information or documentation pursuant to this Section 3.4(a) has agreed with the Servicer to be
bound by any confidentiality provisions reasonably requested by the Servicer and shall upon request execute and deliver a separate confidentiality
agreement memorializing such provisions. Unless an Event of Default that has not been waived in accordance with the terms hereof shall
have occurred, any out-of-pocket costs and expenses incident to the exercise by the Indenture Trustee or any Noteholder of any right under
this Section 3.4 shall be borne by the requesting Noteholder(s). The parties hereto acknowledge that the Indenture Trustee
shall not exercise any right pursuant to this Section 3.4 prior to any event set forth in the preceding sentence unless directed
to do so by a group of Interested Noteholders, and the Indenture Trustee has been provided with indemnity satisfactory to it by such Interested
Noteholders. The Indenture Trustee shall have no liability for action or inaction in accordance with the preceding sentence.

 

In the event that such rights
are exercised following the occurrence of an Event of Default that has not been waived in accordance with the terms hereof and is continuing,
all reasonable and customary out-of-pocket costs and expenses actually incurred by the Indenture Trustee shall be borne by PLS. Prior
to any such payment, PLS shall be provided with commercially reasonable documentation of such costs and expenses. Notwithstanding anything
contained in this Section 3.4 to the contrary, in no event shall the books of account, records, reports and other papers of
PLS or the Issuer relating to the Portfolio Mortgage Loans and the Participation Certificates be examined by independent certified public
accountants at the direction of the Indenture Trustee or any Interested Noteholder pursuant to the exercise of any right under this Section 3.4
more than one time during any 12 month period at the expense of the Administrator, unless an Event of Default has occurred that has not
been waived in accordance with the terms hereof during such twelve-month period, in which case more than one examination may be conducted
during a twelve-month period, but such extra audits shall be at the sole expense of the Noteholder(s) requesting such audit(s).

 

    	 	28	 

     

    

 

(b)          Access
to Issuer. The Issuer agrees that, on reasonable prior notice, it will permit any representative of the Indenture Trustee (at the
written direction of the Majority Noteholders), the MSR Valuation Agent or the Administrative Agent at the expense of the Administrator
no more than one time during any 12-month period (unless an Event of Default has occurred that has not been waived in accordance with
the terms hereof during such twelve-month period, in which case more than one examination may be conducted during a twelve-month period,
but such extra audits shall be at the sole expense of the party requesting such audit(s)), to examine all of its books of account, records,
reports, and other papers, to make copies and extracts therefrom, to cause such books to be audited by independent certified public accountants,
and to discuss its affairs, finances and accounts its officers, employees, and independent certified public accountants, all at such reasonable
times and as often as may be reasonably requested. The Indenture Trustee, the MSR Valuation Agent and the Administrative Agent shall and
shall cause their respective representatives to hold in confidence all such information except to the extent disclosure may be required
by law (and all reasonable applications for confidential treatment are unavailing) or the Indenture Trustee, the MSR Valuation Agent or
the Administrative Agent, as applicable, may reasonably determine that such disclosure is consistent with its obligations hereunder; provided,
however, that the Indenture Trustee may disclose on a confidential basis any such information to its agents, attorneys and auditors
in connection with the performance of its responsibilities hereunder. Without limiting the generality of the foregoing, neither the Indenture
Trustee, the MSR Valuation Agent or the Administrative Agent shall disclose information to any of its Affiliates or any of their respective
directors, officers, employees and agents, that may provide any servicer advance financing to PLS, the Issuer or any of their Affiliates,
except in such Affiliate’s capacity as Noteholder.

Article IV

 

The Trust Accounts; Payments

 

		Section 4.1.	Trust Accounts.

 

The Indenture Trustee shall
establish and maintain, or cause to be established and maintained, (i) the Trust Accounts (other than the Expense Reserve Account),
each of which shall be an Eligible Account, for the benefit of the Secured Parties, and (ii) an Expense Reserve Account, which shall
be an Eligible Account, for the benefit of the Indenture Trustee and the MSR Valuation Agent. All amounts held in the Trust Accounts shall,
to the extent permitted by this Base Indenture and applicable laws, rules and regulations, be invested in Permitted Investments by
the depository institution or trust company then maintaining such Trust Account only upon written direction of the Administrator to the
Indenture Trustee; provided, however, that in the event the Administrator fails to provide such written direction to the
Indenture Trustee, and until the Administrator provides such written direction, the Indenture Trustee shall not invest funds on deposit
in any Trust Account. Funds deposited into a Trust Account on a Business Day after 1:30 p.m. New York City time will not be invested
until the following Business Day. Investments held in Permitted Investments in the Trust Accounts shall not be sold or disposed of prior
to their maturity (unless an Event of Default has occurred). Earnings on investment of funds in any Trust Account shall be remitted by
the Indenture Trustee upon the Administrator’s request to the account or other location of the Administrator’s designation
on the first (1st) Business Day of the month following the month in which such earnings on investment of funds is received.
Any losses and investment expenses relating to any investment of funds in any Trust Account shall be for the account of the Administrator,
which shall deposit or cause to be deposited the amount of such loss (to the extent not offset by income from other investments of funds
in the related Trust Account) in the related Trust Account promptly upon the realization of such loss. The taxpayer identification number
associated with each of the Trust Accounts shall be that of the Issuer, and the Issuer shall report for federal, state and local income
tax purposes their respective portions of the income, if any, earned on funds in the relevant Trust Account. The Administrator hereby
acknowledges that all amounts on deposit in each Trust Account (excluding investment earnings on deposit in the Trust Accounts) are held
in trust by the Indenture Trustee for the benefit of the Secured Parties, subject to any express rights of the Issuer set forth herein,
and shall remain at all times during the term of this Base Indenture under the sole dominion and control of the Indenture Trustee. All
Trust Accounts shall be non-interest bearing trust accounts.

 

    	 	30	 

     

    

 

So long as the Indenture Trustee
complies with the provisions of this Section 4.1, the Indenture Trustee shall not be liable for the selection of investments
or for investment losses incurred thereon by reason of investment performance, liquidation prior to stated maturity or otherwise in any
Trust Account. The Indenture Trustee shall have no liability in respect of losses incurred in any Trust Account as a result of the liquidation
of any investment prior to its stated maturity or the failure to be provided with timely written investment direction.

 

In order to comply with the
laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating
to the funding of terrorist activities and money laundering, including Section 326 of the USA Patriot Act of the United States (“Applicable
Law”), the Indenture Trustee is required to obtain, verify, record and update certain information relating to individuals
and entities which maintain a business relationship with the Indenture Trustee. Accordingly, each of the parties agrees to provide to
the Indenture Trustee upon its request from time to time such identifying information and documentation as may be available for such party
in order to enable the Indenture Trustee to comply with Applicable Law.

 

All parties to this Base Indenture
agree, and each Noteholder of each Series by its acceptance of the related Note will be deemed to have agreed, that such Noteholder
shall have no claim or interest in the amounts on deposit in any Trust Account created under this Base Indenture or any related Indenture
Supplement related to an unrelated Series except as expressly provided herein or therein.

 

The Indenture Trustee or its
Affiliates are permitted to receive additional compensation that could be deemed to be for the Indenture Trustee’s economic self-interest
for (a) serving as investment adviser, administrator, shareholder, servicing agent with respect to certain of the Permitted Investments,
(b) using Affiliates to effect transactions in certain Permitted Investments and (c) effecting transactions in certain Permitted

Securities Intermediary’s jurisdiction for purposes of the UCC, and the laws of the State of New York are applicable to all issues
specified in Article 2(1) of the Hague Securities Convention. This Base Indenture is the only “account agreement”
in respect of the Trust Accounts.

 

		Section 4.2.	Collections and Disbursements of Portfolio Collections by
Servicer.

 

(a)          Daily
Deposits of Portfolio Amounts. The Servicer shall remit all Portfolio Collections in accordance with the respective Participation
Certificates, Participation Agreements and the PC Repurchase Agreement. Any amounts that shall be remitted to the Issuer shall be remitted
directly to the Collection and Funding Account.

 

    	 	31	 

     

    

 

(b)          Payment
Dates. On each Payment Date, the Indenture Trustee shall transfer from the Collection and Funding Account to the Note Payment Account
all necessary funds then on deposit therein. Except in the case of Redemption Amounts, which may be remitted by the Issuer directly to
the Note Payment Account, none of the Servicer, the Administrator, the Issuer, the Calculation Agent nor the Indenture Trustee shall remit
to the Note Payment Account, and each shall take all reasonable actions to prevent other Persons from remitting to the Note Payment Account,
amounts which do not constitute payments, collections or recoveries received, made or realized in respect of the Participation Certificates
or the other Collateral or the initial cash, if any, deposited by the Noteholders with the Indenture Trustee on the date hereof, and the
Indenture Trustee will return to the Issuer or the Servicer any such amounts upon receiving written evidence reasonably satisfactory to
the Indenture Trustee that such amounts are not a part of the Trust Estate.

 

		Section 4.3.	Fundings.

 

(a)          Funding
Certifications. By no later than 3:00 p.m. New York City time on the second (2nd) Business Day prior to each Funding
Date (or such other time as may be agreed to from time to time by the Administrator, the Indenture Trustee and the Administrative Agent),
the Administrator shall prepare and deliver to the Issuer, the Indenture Trustee, the Calculation Agent and the Administrative Agent (and,
on any Interim Payment Date, each applicable VFN Noteholder) a certification (each, a “Funding Certification”)
containing a list of each Funding Condition and presenting a “yes” or “no” answer beside each indicating whether
such Funding Condition has been satisfied and shall state in writing the amount to be funded on that Funding Date.

 

		(b)	VFN Draws, Discretionary Paydowns
and Permanent Reductions.

 

With respect to each VFN:

 

(i)          From
time to time, the Collateral Value may increase due to (i) the addition of Mortgage Loans to the Retained MSR Portfolio or (ii) increases
in the value of the MSRs that underlie the Retained MSR Portfolio. By no later than 3:00 p.m. New York City time on the second (2nd)
Business Day prior to any Payment Date or Interim Payment Date during the Revolving Period for such VFN on which any applicable Variable
Funding Note Class is Outstanding, the Administrator, on behalf of the Issuer, may deliver, or cause to be delivered, to each Noteholder
of such Variable Funding Notes and to the Indenture Trustee a Funding Certification and a report (a “VFN Note Balance Adjustment
Request”) for such upcoming Funding Date, requesting such Noteholders to fund a VFN Principal Balance increase on any Class or
Classes of VFNs in the amount(s) specified in such request, which request shall instruct the Indenture Trustee to recognize an increase
in the related VFN Principal Balance, but not in excess of the lesser of (x) the related Maximum VFN Principal Balance or (y) the
amount that would cause a Borrowing Base Deficiency. The VFN Note Balance Adjustment Request shall also state the amount, if any, of any
principal payment to be made on each Outstanding Class of VFNs on the upcoming Interim Payment Date or Payment Date. The amount to
be funded shall be based on the change in Collateral Value from the most recent Interim Payment Date or Payment Date.

 

    	 	32	 

     

    

 

(ii)         If
the related Funding Certification indicates that all Funding Conditions have been met, and the Administrative Agent agrees, in its sole
discretion, the applicable VFN Funding Sources shall fund the VFN Principal Balance increase by remitting pro rata (based on each
such VFN Funding Source’s percentage of the Maximum VFN Principal Balance) the amount stated in the request to the Indenture Trustee
by 12:00 p.m. (noon) New York City time on the related Funding Date, whereupon the Indenture Trustee shall adjust its records to
reflect the increase of the VFN Principal Balance (which increase shall be the aggregate of the amounts received by the Indenture Trustee
from the applicable VFN Funding Sources) by the later of (i) 2:00 p.m. New York City time on such Funding Date, or (ii) two
hours after the receipt by the Indenture Trustee of such funds from the VFN Funding Sources, so long as, after such increase, no Borrowing
Base Deficiency will exist, determined based on the VFN Note Balance Adjustment Request and Determination Date Report. The Indenture Trustee
shall be entitled to rely conclusively on any VFN Note Balance Adjustment Request and the related Determination Date Report and Funding
Certification. The Indenture Trustee shall make available on a password-protected portion of its website to the Issuer or its designee
and each applicable VFN Funding Source and any related VFN Noteholder, notice on such Funding Date as reasonably requested by the Issuer
of any increase in the VFN Principal Balance. The Indenture Trustee shall apply and remit any such payment by the VFN Funding Sources
toward the payment of the related Funding Amounts as described in Section 4.3(c). If on any Funding Date there is more than

which there are one or more Classes of Notes may specify the allocation of payments among such Classes payable pursuant to Section 4.5
hereof, providing for the subordination of such payments on the subordinated Series or Class, and any such provision in such an Indenture
Supplement shall have the same effect as if set forth in this Base Indenture and any related Indenture Supplement, all to the extent an
Issuer Tax Opinion is delivered as to such Series at its issuance.

 

(d)            On
each Payment Date, the Indenture Trustee shall make available, in the same manner as described in Section 3.5, a report stating

Section 4.6.            Series Reserve
Account; Expense Reserve Account.

 

(a)            Series Reserve
Account.

 

(i)            Pursuant
to Section 4.1, the Indenture Trustee shall establish and maintain a Series Reserve Account or Trust Accounts for each
Series, each of which shall be an Eligible Account, for the benefit of the Secured Parties of such Series. If any such account loses its
status as an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty
(30) days. On or prior to the Issuance Date for each Series, the Issuer shall cause an amount equal to the related Series Reserve
Required Amount(s), if applicable, to be deposited into the related Series Reserve Account(s). Thereafter, on each Payment Date and
Interim Payment Date, the Indenture Trustee shall withdraw Available Funds from the Note Payment Account and deposit them into each such
Series Reserve Account pursuant to, and to the extent required by, Section 4.5(a) and the related Indenture Supplement.

 

(ii)            On
each Payment Date, an amount equal to the aggregate of amounts described in clauses (i), (ii) and (iii) of
Section 4.5(a)(1) or clauses (i) and (ii) of Section 4.5(a)(2) allocable to
the related Series, as appropriate, and which is not payable out of Available Funds or the related VFN Series Available Funds or
Term Note Series Available Funds, as applicable, due to an insufficiency of Available Funds or VFN Series Available Funds or
Term Note Series Available Funds, as applicable, shall be withdrawn from such Series Reserve Account by the Indenture Trustee
and remitted to the Note Payment Account for payment in respect of the related Class’ allocable share of such items as described
in Section 4.5(a) or the related Indenture Supplement. On any Payment Date on which amounts are withdrawn from such Series Reserve
Account pursuant to Section 4.5(a), no funds shall be withdrawn from the Collection and Funding Account (or from the Note
Payment Account for deposit into the Collection and Funding Account) to pay Funding Amounts or amounts to the Issuer pursuant to Section 4.3
if, after giving effect to the withdrawals described in the preceding sentences, the amount then on deposit in such Series Reserve
Account is less than the related Series Reserve Required Amount, if applicable. All Collections received in the Collection and Funding
Account shall be deposited into the related Series Reserve Accounts until the amount on deposit in each Series Reserve Account
equals the related Series Reserve Required Amount, if applicable, as described in Section 4.5 and the related Indenture
Supplement. For purposes of the foregoing, the portion of any such fees and expenses payable under Section 4.5(a)(1)(i) or
(ii) shall equal the related Series Allocation Percentage of the amounts payable under such clause.

 

    40

     

    

 

(iii)           If
on any Payment Date the amount on deposit in a Series Reserve Account is equal to or greater than the aggregate Note Balance for
the related Series (after payment on such Payment Date of the amounts described in Section 4.5) the Indenture Trustee
will withdraw from such Series Reserve Account the aggregate Note Balance for such Series and remit it to the Noteholders of
the Notes of such Series in reduction of the aggregate Note Balance for all Classes of Notes of such Series that are Outstanding.
On the Stated Maturity Date for the latest maturing Class in a Series, the balance on deposit in the related Series Reserve
Account shall be applied as a principal payment on the Notes of that Series to the extent necessary to reduce the aggregate Note
Balance for that Series to zero. On any Payment Date after payment of principal on the Notes and when no Event of Default has occurred,
the Indenture Trustee shall withdraw from each Series Reserve Account the amount by which the balance of the Series Reserve
Account exceeds the related Series Reserve Required Amount, if applicable, and pay such amount to PLS as holder of the Owner Trust
Certificate.

 

(iv)           Amounts
held in a Series Reserve Account shall be invested in Permitted Investments to the extent the Administrator provides written direction
to the Indenture Trustee, as provided in Section 4.1; provided, however, if no such direction is provided, all
amounts shall remain uninvested.

 

(v)            On
any Payment Date, after payment of all amounts pursuant to Section 4.5(a), during the Full Amortization Period, the Indenture
Trustee shall withdraw from each Series Reserve Account the amount by which the amount on deposit in such Series Reserve Account
exceeds the related Series Reserve Required Amount, if applicable, and shall apply such excess to reduce the Note Balances of the
Notes of the related Series, pursuant to Section 4.5. Such principal payment shall be made in accordance with the terms and
provisions of the related Indenture Supplement. On any Payment Date following the payment in full of all principal payable in respect
of the related Series or Class of Notes, the Indenture Trustee shall withdraw any remaining amounts from the related Series Reserve
Account and distribute it to PLS as holder of the Owner Trust Certificate. Amounts paid to PLS or its designee pursuant to the preceding
sentence shall be released from the Security Interest.

 

(vi)           If
on any Funding Date, the amount on deposit in one or more Series Reserve Accounts is less than the related Series Reserve Required
Amounts, if applicable, then the Administrator may direct the Indenture Trustee to transfer from the Collection and Funding Account to
such Series Reserve Accounts an amount equal to the amount by which the respective Series Reserve Required Amounts, if applicable,
exceed the respective amounts then on deposit in the related Series Reserve Accounts.

 

(vii)          Any
funds on deposit in any Series Reserve Account are to be applied to make any required payments in respect of the related Series or
Class of Notes only, and no other Series or Class of Notes shall have any interest or claim against such amounts on deposit.
Notwithstanding the foregoing, if any Series or Class of Notes is deemed to have an interest or claim on the funds on deposit
in the Series Reserve Account established for another Series, it shall not receive any amounts on deposit in such Series Reserve
Account unless and until the Series or Class of Notes related to such Series Reserve Account are paid in full and are no
longer Outstanding. The provisions of this Section 4.6(a)(vii) constitute a “subordination agreement” for
purposes of Section 510(a) of the Bankruptcy Code.

the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. On or prior to the
Closing Date, the Issuer shall cause an amount equal to the related Expense Reserve Required Amount to be deposited into the Expense Reserve
Account. Thereafter, on each Payment Date and Interim Payment Date, the Indenture Trustee shall withdraw Available Funds from the Note
Payment Account and deposit them into the Expense Reserve Account pursuant to, and to the extent required by Section 4.5(a).

 

(ii)            On
each Payment Date, an amount equal to the aggregate of amounts described in clause (i) of Section 4.5(a)(2) which
is not payable out of Series Available Funds due to an insufficiency of Series Available Funds shall be withdrawn from the Expense
Reserve Account by the Indenture Trustee and remitted to the Note Payment Account for payment in respect of the related Class’ allocable
share of such items as described in Section 4.5(a). On any Payment Date on which amounts are withdrawn from the Expense Reserve
Account pursuant to Section 4.5(a), no funds shall be withdrawn from the Collection and Funding Account (or from the Note
Payment Account for deposit into the Collection and Funding Account) to pay Funding Amounts or amounts to the Issuer pursuant to Section 4.3
if, after giving effect to the withdrawals described in the preceding sentences, the amount then on deposit in the Expense Reserve Account
is less than the Expense Reserve Required Amount. All Collections received in the Collection and Funding Account shall be deposited into
the Expense Reserve Account until the amount on deposit in the Expense Reserve Account equals the Expense Reserve Required Amount, as
described in Section 4.5.

 

(iii)           Amounts
held in the Expense Reserve Account shall be invested in Permitted Investments at the direction of the Administrator as provided in Section 4.1.

 

(iv)            On
any Payment Date, after payment of all amounts pursuant to Section 4.5(a), during the Full Amortization Period, the Indenture
Trustee shall withdraw from the Expense Reserve Account the amount by which the amount on deposit in the Expense Reserve Account exceeds
the Expense Reserve Required Amount, if applicable, and shall apply such excess to reduce the Note Balances of the Notes of all Series,
pursuant to Section 4.5. Such principal payment shall be made in accordance with the terms and provisions of the related Indenture
Supplement. On any Payment Date following the payment in full of all principal payable in respect of all Series or Classes of Notes
and the payment in full of all amounts payable to the Indenture Trustee and the MSR Valuation Agent, the Indenture Trustee shall withdraw
any remaining amounts from the Expense Reserve Account and distribute it to PLS as holder of the Owner Trust Certificate. Amounts paid
to PLS or its designee pursuant to the preceding sentence shall be released from the Security Interest.

 

    42

     

    

 

(v)            If
on any Funding Date, the amount on deposit in the Expense Reserve Accounts is less than the Expense Reserve Required Amount, if applicable,
then the Administrator may direct the Indenture Trustee to transfer from the Collection and Funding Account to the Expense Reserve Account
an amount equal to the amount by which the Expense Reserve Required Amount exceeds the amounts then on deposit in the Expense Reserve
Account.

 

Section 4.7.            Collection

Pursuant to Section 4.1,
the Indenture Trustee shall establish and maintain the Collection and Funding Account and the Eligible Securities Account, each of which

funds or securities, as applicable, in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30)
days. The Indenture Trustee shall deposit and withdraw Available Funds from the Collection and Funding Account pursuant to, and to the
extent required by Section 4.5.

 

Amounts held in the Collection
and Funding Account shall be invested in Permitted Investments at the written direction of the Administrator as provided in Section 4.1;

(a)            Pursuant
to Section 4.1, the Indenture Trustee shall establish and maintain the Note Payment Account, which shall be an Eligible Account,
for the benefit of the Secured Parties. If the Note Payment Account loses its status as an Eligible Account, the funds in such account
shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. The Note Payment Account shall be funded to

Section 4.9.            Securities
Accounts.

 

(a)             Securities
Intermediary. The Issuer and the Indenture Trustee hereby appoint Citibank, as Securities Intermediary with respect to the Trust Accounts.
The Security Entitlements and all Financial Assets credited to the Trust Accounts, including all amounts, securities, investments, Financial
Assets, investment property and other property from time to time deposited in or credited to such account and all proceeds thereof, held
from time to time in the Trust Accounts will continue to be held by the Securities Intermediary for the Indenture Trustee for the benefit
of the Secured Parties. Upon the termination of this Base Indenture, the Indenture Trustee shall inform the Securities Intermediary of
such termination. By acceptance of their Notes or interests therein, the Noteholders and all beneficial owners of Notes shall be deemed
to have appointed Citibank, as Securities Intermediary. Citibank hereby accepts such appointment as Securities Intermediary.

 

(i)            With
respect to any portion of the Trust Estate that is credited to the Trust Accounts, the Securities Intermediary agrees that:

 

(A)          with
respect to any portion of the Trust Estate that is held in deposit accounts, each such deposit account shall be subject to the security
interest granted pursuant to this Base Indenture, and the Securities Intermediary shall comply with instructions originated by the Indenture
Trustee directing dispositions of funds in the deposit accounts without further consent of the Issuer and otherwise shall be subject to
the exclusive custody and control of the Securities Intermediary, and the Securities Intermediary shall have sole signature authority
with respect thereto;

 

(B)          any
and all property credited to the Trust Accounts shall be treated by the Securities Intermediary as Financial Assets;

 

(C)          any
portion of the Trust Estate that is, or is treated as, a Financial Asset shall be physically delivered (accompanied by any required endorsements)
to, or credited to an account in the name of, the Securities Intermediary or other eligible institution maintaining any Trust Account
in accordance with the Securities Intermediary’s customary procedures such that the Securities Intermediary or such other institution
establishes a Security Entitlement in favor of the Indenture Trustee, for the benefit of the Noteholders, with respect thereto over which
the Securities Intermediary or such other institution has “control” (as defined in the UCC); and

 

(D)          it
will use reasonable efforts to promptly notify the Indenture Trustee and the Issuer if any other Person claims that it has a property
interest in a Financial Asset in any Trust Account and that it is a violation of that Person’s rights for anyone else to hold, transfer
or deal with such Financial Asset.

 

    44

     

    

 

(ii)            The
Securities Intermediary hereby confirms that (A) each Trust Account is an account to which Financial Assets are or may be credited,
and the Securities Intermediary shall, subject to the terms of this Base Indenture treat the Indenture Trustee as entitled to exercise
the rights that comprise any Financial Asset credited to any Trust Account, (B) any portion of the Trust Estate in respect of any
Trust Account will be promptly credited by the Securities Intermediary to such account, and (C) all securities or other property
underlying any Financial Assets credited to any Trust Account shall be registered in the name of the Securities Intermediary, endorsed
to the Securities Intermediary or in blank or credited to another securities account maintained in the name of the Securities Intermediary,
and in no case will any Financial Asset credited to any Trust Account be registered in the name of the Issuer or the Administrator, payable
to the order of the Issuer or the Administrator or specially endorsed to any of such Persons.

 

(iii)            If
at any time the Securities Intermediary shall receive an Entitlement Order from the Indenture Trustee directing transfer or redemption
of any Financial Asset relating to any Trust Account, the Securities Intermediary shall comply with such Entitlement Order without further
consent by the Issuer or the Administrator or any other Person. If at any time the Indenture Trustee notifies the Securities Intermediary
in writing that this Base Indenture has been discharged in accordance herewith, then thereafter if the Securities Intermediary shall receive
any order from the Issuer directing transfer or redemption of any Financial Asset relating to any Trust Account, the Securities Intermediary
shall comply with such Entitlement Order without further consent by the Indenture Trustee or any other Person.

 

(iv)            In
the event that the Securities Intermediary has or subsequently obtains by agreement, operation of law or otherwise a security interest
in any Trust Account or any Financial Asset or Security Entitlement credited thereto, the Securities Intermediary hereby agrees that such
security interest shall be subordinate to the security interest of the Indenture Trustee. The Financial Assets and Security Entitlements
credited to the Trust Accounts will not be subject to deduction, set-off, banker’s lien, or any other right in favor of any Person
other than (i) the Indenture Trustee in the case of the Trust Accounts and (ii) the Owner Trustee Lien.

 

(v)            There
are no other agreements entered into between the Securities Intermediary in such capacity, and the Securities Intermediary agrees that
it will not enter into any agreement with, the Issuer, the Administrator, or any other Person (other than the Indenture Trustee) with
respect to any Trust Account. In the event of any conflict between this Base Indenture (or any provision of this Base Indenture) and any
other agreement now existing or hereafter entered into, the terms of this Base Indenture shall prevail.

 

(vi)           The
rights and powers granted herein to the Indenture Trustee have been granted in order to perfect its interest in the Trust Accounts and
the Security Entitlements to the Financial Assets credited thereto, and are powers coupled with an interest and will not be affected by
the bankruptcy of the Issuer, the Administrator or PLS nor by the lapse of time. The obligations of the Securities Intermediary hereunder
shall continue in effect until the interest of the Indenture Trustee in the Trust Accounts and in such Security Entitlements, has been
terminated pursuant to the terms of this Base Indenture and the Indenture Trustee has notified the Securities Intermediary of such termination
in writing.

 

    45

     

    

 

(b)            Definitions;
Choice of Law. Capitalized terms used in this Section 4.9 and not defined herein shall have the meanings assigned to such
terms in the New York UCC. For purposes of Section 8-110(e) of the New York UCC, the “securities intermediary’s
jurisdiction” shall be the State of New York. The Securities Intermediary, the Administrator and the Issuer agree that they will
not change the applicable law in force with respect to issues referred to in Article 2(1) of the Hague Securities Convention
to a state other than the State of New York.

 

(c)            Limitation
on Liability. None of the Securities Intermediary or any director, officer, employee or agent of the Securities Intermediary shall
be under any liability to the Indenture Trustee or the Noteholders for any action taken, or not taken, in good faith pursuant to this
Base Indenture, or for errors in judgment; provided, however, that this provision shall not protect the Securities Intermediary
against any liability to the Indenture Trustee or the Noteholders which would otherwise be imposed by reason of the Securities Intermediary’s
willful misconduct, bad faith or negligence in the performance of its obligations or duties hereunder. The Securities Intermediary and
any director, officer, employee or agent of the Securities Intermediary may rely in good faith on any document of any kind which, on its
face, is properly executed and submitted by any Person respecting any matters arising hereunder. The Securities Intermediary shall be
under no duty to inquire into or investigate the validity, accuracy or content of such document.

 

(d)            Representations,
Warranties and Covenants of the Securities Intermediary. The Securities Intermediary represents and warrants that, as of the date
hereof, the Securities Intermediary has a physical office in the United States and is engaged in a business or other regular activity
of maintaining securities accounts. The Securities Intermediary agrees that, at all times while this Indenture is in effect, it shall
maintain a physical office in the United States that satisfies the criteria set forth in Article 4(1)(a) or (b) of the
Hague Securities Convention.

 

Section 4.10.          Notice
of Adverse Claims.

 

Except for the claims and
interests of the Secured Parties in the Trust Accounts, the Securities Intermediary has no actual knowledge of any claim to, or interest
in, any Trust Account or in any financial asset credited thereto. If any Person asserts any Adverse Claim (including any writ, garnishment,
judgment, warrant of attachment, execution or similar process) against any Trust Account or in any financial asset carried therein of
which a Responsible Officer of the Securities Intermediary has actual knowledge, the Securities Intermediary will promptly notify the
Noteholders, the Indenture Trustee and the Issuer thereof.

 

Section 4.11.          No
Gross Up.

 

No Person, including the Issuer,
shall be obligated to pay any additional amounts to the Noteholders or Note Owners as a result of any withholding or deduction for, or
on account of, any present or future taxes, duties, assessments or governmental charges.

Section 4.12.          Advance
Rate Trigger Event Trigger Period, Early Amortization Period and Full Amortization Period.

 

Upon the occurrence of an
Advance Rate Trigger Event, the Advance Rate Trigger Event shall continue, unless, the Majority Noteholders for each Series of Variable
Funding Notes that are Outstanding, plus the Administrative Agent, notify the Indenture Trustee and the Disposition Manager that either
(i) they have waived the occurrence of such Advance Rate Trigger Event or (ii) they have acknowledged that the Advance Rate
Trigger Event has been cured for each Outstanding Series of Variable Funding Notes that is still in its Revolving Period.

 

Upon the occurrence of an
Early Amortization Event, the Revolving Period for all Classes and Series of the Notes shall automatically terminate and the Early
Amortization Period for all Outstanding Notes shall commence without further action on the part of any Person, unless, together, the Majority
Noteholders of all Outstanding Notes that are not Variable Funding Notes and the Majority Noteholders for each Series of Variable
Funding Notes that are Outstanding, plus the Administrative Agent, notify the Indenture Trustee and the Disposition Manager that either
(i) they have waived the occurrence of such Early Amortization Event and consent to the continuation of the Revolving Period for
each Outstanding Series that is still in its Revolving Period or (ii) they acknowledge that the Early Amortization Event has
been cured and consent to the continuation of the Revolving Period for each Outstanding Series that is still in its Revolving Period.

 

Upon the occurrence of an
Event of Default, the Revolving Period for all Classes and Series of the Notes shall automatically terminate and the Full Amortization
Period for all Outstanding Notes shall commence without further action on the part of any Person, unless, together, the Majority Noteholders
of all Outstanding Notes that are not Variable Funding Notes and the Majority Noteholders for each Series of Variable Funding Notes
that are Outstanding, plus the Administrative Agent, notify the Indenture Trustee and the Disposition Manager that either (i) they
have waived the occurrence of such Event of Default and consent to the continuation of the Revolving Period for each Outstanding Series that
is still in its Revolving Period or (ii) they acknowledge that the Event of Default has been cured and consent to the continuation
of the Revolving Period for each Outstanding Series that is still in its Revolving Period; provided, upon waiver or cure of
an Event of Default and continuation of a Revolving Period, any hourly fees incurred by the Disposition Manager during any Default Period
shall be paid on the immediately following Payment Date pursuant to Section 4.5(a)(1)(ii).

 

The obligation of the Issuer
to pay or reserve any Default Supplemental Fee, Step-Up Fee, Cumulative Interest Shortfall Amount, Cumulative Default Supplemental Fee
Shortfall Amount or Cumulative Step-Up Fee Shortfall Amount shall begin only upon the occurrence of an Early Amortization Event or Event
of Default, as applicable, and commencement of the Early Amortization Period or Full Amortization Period, as applicable, as described
in this Section 4.12.

Section 5.4.            Book-Entry
Notes.

 

(a)            Issuance
of Book-Entry Notes. If the Issuer establishes pursuant to Sections 5.2 and 6.1 that the Notes of a particular
Series or Class are to be issued as Book-Entry Notes, then the Issuer will execute and the Indenture Trustee or its agent will,
in accordance with Section 6.3 and with the Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3,
authenticate and deliver, one or more definitive Global Notes, which, unless otherwise provided in the applicable Indenture Supplement
(1) will represent, and will be denominated in an amount equal to the aggregate, Initial Note Balance of the Outstanding Notes
of such Series or Class to be represented by such Global Note or Notes, or such portion thereof as the Issuer will specify in
an Issuer Certificate, (2) will be registered in the name of the Depository for such Global Note or Notes or its nominee, (3) will
be delivered by the Indenture Trustee or its agent to the Depository or pursuant to the Depository’s instruction (and which may

(4) if applicable, will bear a legend substantially to the following effect: “Unless this Note is presented by an authorized
representative of The Depository Trust Company, a New York corporation (“DTC”), to the Issuer or its agent for
registration of transfer, exchange or payment, and any Note issued is registered in the name of Cede & Co. or in such other name
as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested
by an authorized representative of DTC), any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful
inasmuch as the registered owner hereof, Cede & Co., has an interest herein” and (5) may bear such other legend as
the Issuer, upon advice of counsel, deems to be applicable.

 

(b)            The
Note Registrar and the Indenture Trustee may deal with the Depository as the sole Noteholder of the Book-Entry Notes for all purposes
of this Indenture and will not be obligated to the Note Owners, except as stated in Section 14.11.

 

(c)            The
rights of the Note owners may be exercised only through the Depository and will be limited to those established by law and agreements
between the Note Owners and the Depository and/or its participants under the Depository Agreement.

 

    49

     

    

 

(d)            If
this Section 5.4(a) conflicts with other terms of this Indenture, this Section 5.4(a) will control.

 

(e)            The
Depository will make book-entry transfers among its participants and receive and transmit payments of principal of and interest on the
Book-Entry Notes to the participants.

 

(f)            The
Indenture Trustee, the Note Registrar, and the Paying Agent shall have no responsibility or liability for any actions taken or not taken
by the Depository.

 

(g)            If
this Indenture requires or permits actions to be taken based on instructions or directions of the Noteholders of a stated percentage of
Note Balance of the Notes, the Depository will be deemed to represent those Noteholders only if it has received instructions to that effect
form Note Owners and/or the Depository’s participants owning or representing, the required percentage of the beneficial interest
of the Notes and has delivered the instructions to the Indenture Trustee.

 

(h)            The
Issuer in issuing Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Indenture Trustee shall use “CUSIP”
numbers in notices of redemption as a convenience to Noteholders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in
or omission of such numbers. The Issuer will promptly notify the Indenture Trustee in writing of any change in the “CUSIP”
numbers.

 

(i)             Transfers
of Global Notes only to Depository Nominees. Notwithstanding any other provisions of this Section 5.4 or of Section 6.5,
and subject to the provisions of paragraph (c) below, unless the terms of a Global Note or the applicable Indenture Supplement expressly
permit such Global Note to be exchanged in whole or in part for individual Notes, a Global Note may be transferred, in whole but not in
part and in the manner provided in Section 6.5, only to a nominee of the Depository for such Global Note, or to the Depository,
or a successor Depository for such Global Note selected or approved by the Issuer, or to a nominee of such successor Depository.

 

(j)             Limited
Right to Receive Definitive Notes. Except under the limited circumstances described below, Note Owners of beneficial interests in
Global Notes will not be entitled to receive Definitive Notes. With respect to Notes issued within the United States, unless otherwise
specified in the applicable Indenture Supplement, or with respect to Notes issued outside the United States, if specified in the applicable
Indenture Supplement:

 

(i)              If
at any time the Depository for a Global Note notifies the Issuer that it is unwilling or unable to continue to act as Depository for such
Global Note or if at any time the Depository for the Notes for such Series or Class ceases to be a Clearing Corporation, the
Issuer will appoint a successor Depository with respect to such Global Note. If a successor Depository for such Global Note is not appointed
by the Issuer within ninety (90) days after the Issuer receives such notice or becomes aware of such ineligibility, the Issuer will execute,
and the Indenture Trustee or its agent will, in accordance with Section 6.3 and with the Issuer Certificate delivered to the
Indenture Trustee or its agent under Section 6.3 requesting the authentication and delivery of individual Notes of such Series or
Class in exchange for such Global Note, will authenticate and deliver, individual Notes of such Series or Class of like
tenor and terms in an aggregate Initial Note Balance equal to the Initial Note Balance of the Global Note in exchange for such Global
Note.

 

    50

     

    

 

(ii)            The
Issuer may at any time and in its sole discretion determine that the Notes of any Series or Class or portion thereof issued
or issuable in the form of one or more Global Notes will no longer be represented by such Global Note or Notes. In such event the Issuer
will execute, and the Indenture Trustee or its agent in accordance with Section 6.3 and with the Issuer Certificate delivered
to the Indenture Trustee or its agent under Section 6.3 for the authentication and delivery of individual Notes of such Series or
Class in exchange in whole or in part for such Global Note, will authenticate and deliver individual Notes of such Series or
Class of like tenor and terms in definitive form in an aggregate Initial Note Balance equal to the Initial Note Balance of such Global
Note or Notes representing such Series or Class or portion thereof in exchange for such Global Note or Notes.

 

(iii)            If
specified by the Issuer pursuant to Sections 5.2 and 6.1 with respect to Notes issued or issuable in the form of a
Global Note, the Depository for such Global Note may surrender such Global Note in exchange in whole or in part for individual Notes of
such Series or Class of like tenor and terms in definitive form on such terms as are acceptable to the Issuer and such Depository.
Thereupon the Issuer will execute, and the Indenture Trustee or its agent will, in accordance with Section 6.3 and with the
Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3, authenticate and deliver, without service
charge, (A) to each Person specified by such Depository a new Note or Notes of the same Series or Class of like tenor and
terms and of any authorized denomination as requested by such Person in an aggregate Initial Note Balance equal to the Initial Note Balance
of the portion of the Global Note or Notes specified by the Depository and in exchange for such Person’s beneficial interest in
the Global Note; and (B) to such Depository a new Global Note of like tenor and terms and in an authorized denomination equal to
the difference, if any, between the Initial Note Balance of the surrendered Global Note and the aggregate Initial Note Balance of Notes
delivered to the Noteholders thereof.

 

(iv)            If
any Event of Default has occurred with respect to such Global Notes, and Owners of Notes evidencing more than 50% of the Global Notes
of that Series or Class (measured by Voting Interests) advise the Indenture Trustee and the Depository that a Global Note is
no longer in the best interest of the Note Owners, the Owners of Global Notes of that Series or Class may exchange their beneficial
interests in such Notes for Definitive Notes in accordance with the exchange provisions herein.

 

(v)            In
any exchange provided for in any of the preceding four paragraphs, the Issuer will execute and the Indenture Trustee or its agent will,
in accordance with Section 6.3 and with the Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3,
authenticate and deliver Definitive Notes in definitive registered form in authorized denominations. Upon the exchange of the entire Initial
Note Balance of a Global Note for Definitive Notes, such Global Note will be canceled by the Indenture Trustee or its agent. Except as
provided in the preceding paragraphs, Notes issued in exchange for a Global Note pursuant to this Section will be registered in such
names and in such authorized denominations as the Depository for such Global Note, pursuant to instructions from its direct or indirect
participants or otherwise, will instruct the Indenture Trustee or the Note Registrar. The Indenture Trustee or the Note Registrar will
deliver such Notes to the Persons in whose names such Notes are so registered.

been issued to the applicable Noteholders to replace any Global Notes with respect to a Series or Class pursuant to Section 5.4
or as otherwise specified in any applicable Indenture Supplement:

 

(a)            the
Issuer and the Indenture Trustee may deal with the applicable clearing agency or Depository and the Depository Participants for all purposes
(including the making of payments) as the authorized representatives of the respective Note Owners; and

 

(b)            the
rights of the respective Note Owners will be exercised only through the applicable Depository and the Depository Participants and will
be limited to those established by law and agreements between such Note Owners and the Depository and/or the Depository Participants.
Pursuant to the operating rules of the applicable Depository, unless and until Definitive Notes are issued pursuant to Section 5.4,
the Depository will make book-entry transfers among the Depository Participants and receive and transmit payments of principal and interest
on the related Notes to such Depository Participants.

 

For purposes of any provision
of this Base Indenture requiring or permitting actions with the consent of, or at the direction of, Noteholders evidencing a specified
percentage of the Note Balance of Outstanding Notes, such direction or consent may be given by Note Owners (acting through the Depository
and the Depository Participants) owning interests in or security entitlements to Notes evidencing the requisite percentage of principal
amount of Notes.

 

Section 5.6.            Notices
to Depository.

 

Whenever any notice or other
communication is required to be given to Noteholders with respect to which Book-Entry Notes have been issued, unless and until Definitive
Notes will have been issued to the related Note Owners, the Indenture Trustee will give all such notices and communications to the applicable
Depository, and shall have no obligation to report directly to such Note Owners.

Each Series of Notes

Register. The Indenture Trustee, acting as Note Registrar, shall keep or cause to be kept a register (herein sometimes referred to
as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuer will
provide for the registration of Notes, or of Notes of a particular Series or Class, and for transfers of Notes. Any such register
will be in written form or in any other form capable of being converted into written form within a reasonable time. At all reasonable
times the information contained in such register or registers will be available for inspection by the Issuer or the Indenture Trustee
at the Corporate Trust Office. The Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent and any agents of any of them,
may treat a Person in whose name a Note is registered as the owner of such Note for the purpose of receiving payments in respect of such
Note and for all other purposes, and none of the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent or any agent of any
of them, shall be affected by notice to the contrary. None of the Issuer, the Indenture Trustee, any agent of the Indenture Trustee, any
Paying Agent or the Note Registrar will have any responsibility or liability for any aspect of the records relating to or payments made
on account of beneficial ownership of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial
ownership.

 

(b)            Exchange
of Notes. Subject to Section 5.4, upon surrender for transfer of any Note of any Series or Class at the Place
of Payment, the Issuer may execute, and, upon receipt of the documents required by Section 6.3 and such surrendered Note,

or transferees, one or more new Notes of such Series or Class of any authorized denominations, of a like aggregate Initial Note
Balance and Stated Maturity Date and of like terms. Subject to Section 5.4, Notes of any Series or Class may be
exchanged for other Notes of such Series or Class of any authorized denominations, of a like aggregate Initial Note Balance
and Stated Maturity Date and of like terms, upon surrender of the Notes to be exchanged at the Place of Payment. Whenever any Notes are
so surrendered for exchange, the Issuer will execute, and the Indenture Trustee or the related Authenticating Agent will authenticate
and deliver the Notes which the Noteholders making the exchange are entitled to receive.

 

    56

     

    

 

(c)            Issuer
Obligations. All Notes issued upon any transfer or exchange of Notes shall be the valid and legally binding obligations of the Issuer,
evidencing the same debt, and entitled to the same benefits under this Base Indenture, as the Notes surrendered upon such transfer or
exchange.

 

(d)            Endorsement
of Notes to be Transferred or Exchanged. Every Note presented or surrendered for transfer or exchange will (if so required by the
Issuer, the Note Registrar or the Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory
to the Issuer, the Indenture Trustee, and the Note Registrar duly executed, by the Noteholder thereof or such Noteholder’s attorney
duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements
of the Securities Transfer Agent’s Medallion Program.

 

(e)            No
Service Charge. Unless otherwise provided in the Note to be transferred or exchanged, no service charge will be assessed against any
Noteholder for any transfer or exchange of Notes, but the Issuer, the Indenture Trustee, and the Note Registrar may require payment of
a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Notes
before the transfer or exchange will be complete, other than exchanges pursuant to Section 5.4 not involving any transfer.

 

(f)            Deemed
Representations by Transferees of Rule 144A Notes. Each transferee (including the initial Noteholder or Owner) of a Rule 144A
Note or of a beneficial interest therein shall be deemed by accepting such Note or beneficial interest, to have made all the certifications,
representations and warranties set forth in the Rule 144A Note Transfer Certificate attached to Exhibit B-1 attached
hereto.

 

(g)            Deemed
Representations by Transferees of Regulation S Notes. Each transferee (including the initial Noteholder or Owner) of a Regulation

representations and warranties set forth in the Regulation S Note Transfer Certificate attached to Exhibit B-2 attached hereto.

 

(h)           Conditions
to Transfer. No sale, pledge or other transfer (a “Transfer”) of any Notes shall be made unless that Transfer
is made pursuant to an effective registration statement under the 1933 Act and effective registration or qualification under applicable
state securities laws or is made in a transaction that does not require such registration or qualification. If a Transfer is made without
registration under the 1933 Act (other than in connection with the initial issuance thereof by the Issuer), then the Note Registrar, the
Indenture Trustee, Administrator, on behalf of the Issuer, shall refuse to register such Transfer unless the Note Registrar receives either:

 

(i)            the
Regulation S Note Transfer Certificate or Rule 144A Note Transfer Certificate and such other information as may be required pursuant
to this Section 6.5; or

 

(ii)           if
the Transfer is to be made to an Issuer Affiliate in a transaction that is exempt from registration under the 1933 Act, an Opinion of
Counsel reasonably satisfactory to the Issuer and the Note Registrar to the effect that such Transfer may be made without registration
under the 1933 Act (which Opinion of Counsel shall not be an expense of the Trust Estate or of the Issuer, the Indenture Trustee or the
Note Registrar in their respective capacities as such).

 

    57

     

    

 

None of the Administrator,
the Issuer, the Indenture Trustee or the Note Registrar is obligated to register or qualify the Notes under the 1933 Act or any other
securities law or to take any action not otherwise required under this Base Indenture to permit the transfer of any Note without registration
or qualification. Any Noteholder of a Note desiring to effect such a Transfer shall, and upon acquisition of such a Note shall be deemed
to have agreed to, indemnify the Indenture Trustee, the Note Registrar, the Administrator, the Servicer and the Issuer against any liability
that may result if the Transfer is not so exempt or is not made in accordance with the 1933 Act and applicable state securities laws.

 

In connection with any Transfer
of Notes in reliance on Rule 144A, the Administrator shall furnish upon request of a Noteholder to such Noteholder and any prospective
purchaser designated by such Noteholder the information required to be delivered under paragraph (d)(4) of Rule 144A.

 

In the event that a Note is
transferred to a Person that does not meet the requirements of this Section 6.5 and/or the requirements of the related Indenture
Supplement, such transfer will be of no force and effect, will be void ab initio, and will not operate to transfer any right to
such Person, notwithstanding any instructions to the contrary to the Issuer, the Indenture Trustee or any intermediary; and the Indenture
Trustee shall not make any payment on such Note for as long as such Person is the Noteholder of such Note and the Indenture Trustee shall
have the right to compel such Person to transfer such Note to a Person who does meet the requirements of this Section 6.5.

 

(i)            Transfers
of Ownership Interests in Global Notes. Transfers of beneficial interests in a Global Note representing Book-Entry Notes may be made
only in accordance with the rules and regulations of the Depository (and, in the case of a Regulation S Global Note only to beneficial

credited a beneficial interest in a Regulation S Global Note in an amount equal to the beneficial interest in such Rule 144A Global
Note to be exchanged but not less than the minimum denomination applicable to the owner’s Notes held through a Regulation S Global
Note, (B) a written order given in accordance with the Depository’s procedures containing information regarding the participant
account of the Depository and, in the case of a transfer pursuant to and in accordance with Regulation S, the Euroclear or Clearstream

Global Note for the related Series and/or Class and increase the principal amount of the Regulation S Global Note for the related
Series and/or Class by the aggregate principal amount of the beneficial interest in the Rule 144A Global Note to be exchanged,

Note Registrar, to cause to be credited a beneficial interest in a Rule 144A Global Note in an amount equal to the beneficial interest

the Depository to be credited with such increase, and (B) a certificate (each, a “Rule 144A Note Transfer Certificate”)

the principal amount of the Regulation S Global Note and increase the principal amount of the Rule 144A Global Note for the related
Series and/or Class by the aggregate principal amount of the beneficial interest in the Regulation S Global Note for the related
Series and/or Class to be transferred and the Indenture Trustee and the Note Registrar, shall instruct the Depository, concurrently
with such reduction, to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest

(c)            The
right of any Noteholder to receive interest and fees on or principal of any Note shall be subject to any applicable withholding or deduction
imposed pursuant to the Code or other applicable tax law, including foreign withholding and deduction. Any amounts properly so withheld

interest therein, in each case, prior to the first Payment Date after such Noteholder’s acquisition of Notes and at such time or
times required by law or that the Indenture Trustee on behalf of the Issuer or their respective agents may reasonably request, and shall
update or replace such IRS form or documentation in accordance with its terms or its subsequent amendments. Each Noteholder will provide

or if required by applicable law). In each case above, the applicable IRS form or documentation shall be properly completed and signed
under penalty of perjury.

The Issuer, the Indenture

the Note is registered in the Note Registrar as the owner of such Note for the purpose of receiving payment of principal of and (subject
to Section 6.7) interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and neither

Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever,
and all Notes so delivered will be promptly canceled by the Indenture Trustee. No Note will be authenticated in lieu of or in exchange
for any Notes canceled as provided in this Section, except as expressly permitted by this Base Indenture. The Indenture Trustee will dispose
of all canceled Notes in accordance with its customary procedures.

(a)            Issuance

with respect to such additional Series or Class of Notes. The Indenture Trustee shall execute any such Indenture Supplement
without the consent of any Noteholders, the Issuer shall execute the Notes of such Series or Class and the Notes of such Series or
Class shall be delivered to the Indenture Trustee (along with the other deliverables required hereunder) for authentication and delivery.

by the Issuer and, assuming due authentication and delivery by the Indenture Trustee, constitute legal, valid and binding obligations
of the Issuer enforceable in accordance with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization,
insolvency, moratorium or other laws and legal principles affecting creditors’ rights generally from time to time in effect and
to general equitable principles, whether applied in an action at law or in equity) and are entitled to the benefits of this Base Indenture,

and each Indenture Supplement;

 

    64

     

    

 

(iv)          if
any additional conditions to the new issuance are specified in writing to the Issuer by a Note Rating Agency that is at that time rating
any Outstanding Note that will remain Outstanding after the new issuance, the Issuer satisfies such conditions, if they are applicable
to such Notes;

 

(v)           either
(1) the Issuer obtains written confirmation from each Note Rating Agency that is at that time rating any Outstanding Note at the

in the foregoing clause (1), (a) the Administrator shall provide notice of such new issuance to the related Note Rating Agency
and (b) each of the parties that would be Administrative Agents after giving effect to the new issuance shall have provided their
prior written consent to such new issuance which may be given in reliance in part on the Issuer’s Certificate delivered pursuant

(vi)          no
Event of Default shall have occurred and be continuing, as evidenced by an Issuer’s Certificate, unless (a) the proceeds of

the beneficial owner of the Issuer for United States federal income tax purposes and the financing of such Class of VFNs shall be
subject to the requirement for an Issuer Tax Opinion;

 

(x)            for
any new Series with respect to which there is a new Administrative Agent not currently set forth under the terms of the definition

in respect of which the existing Administrative Agent’s consent is required, are paid in full and all related commitments terminated
in writing by the Issuer and any remaining accrued commitment fees paid in full to such terminated Administrative Agent, in connection
with the issuance of the new Series with the different Administrative Agent; and

 

(xi)          any
other conditions specified in the applicable Indenture Supplement; provided, however, that any one of the aforementioned
conditions may be eliminated (other than clause (v) above and the requirement for an Issuer Tax Opinion) or modified as a
condition precedent to any new issuance of a Series or Class of Notes if the Issuer has obtained approval from each Note Rating
Agency that is at that time rating any Outstanding Notes that will remain Outstanding after the new issuance.

 

    65

     

    

 

(c)            No
Notice or Consent Required to or from Existing Noteholders and Owners. Except as provided in Section 6.10(b) above,
the Issuer and the Indenture Trustee will not be required to provide prior notice to or to obtain the consent of any Noteholder or Note

Proceeds. The proceeds of sale of any new Series of Notes shall be wired to the Collection and Funding Account, and the Indenture
Trustee shall disburse such sale proceeds at the direction of the Administrator on behalf of the Issuer, except to the extent such funds
are needed to ensure that no the Borrowing Base Deficiency exists. The Administrator on behalf of the Issuer may direct the Issuer to
apply such proceeds to reduce pro rata based on Invested Amounts, the VFN Principal Balance of any Classes of Variable Funding
Notes, or to redeem any Series of Notes in accordance with Section 13.1. In the absence of any such direction, the proceeds
of such sale shall be distributed to PLS or at PLS’s direction on the Issuance Date for the newly issued Notes. The Administrator
shall deliver to the Indenture Trustee a report demonstrating that the release of sale proceeds pursuant to the Issuer’s direction
will not cause a Borrowing Base Deficiency, as a precondition to the Indenture Trustee releasing such proceeds.

 

(f)            Increase
or Reduction in Maximum VFN Principal Balance. The increase or reduction in the Maximum VFN Principal Balance in respect of any Outstanding
Class of Notes, the increase or decrease of any Advance Rates in respect thereof and/or the increase or decrease of interest rates
in respect thereof shall not constitute an issuance of “new Notes” for purpose of this Section 6.10.

(4)           Holders
of any Term Notes further agree that, from time to time, Fannie Mae and the Servicer have the right to agree to effect amendments to the

the terms of any amendments, restatements, modifications or any other supplements entered into with respect to the Transaction Documents
as may be necessary or advisable in the Administrator’s discretion for the terms of the Transaction Documents to conform to the
terms set forth in any amendments to the Acknowledgment Agreement or changes to the Fannie Mae Guide.

the Noteholders or any Indemnified Party hereunder have not been paid in full.

 

(e)            Any
provision providing for the exercise of any action or discretion by the Indenture Trustee, (i) with respect to Sections 5, 6 or 7

Funding Notes (excluding any Retained Notes) or (iii) the Majority Noteholders for any Series of Variable Funding Notes Outstanding
(excluding any Retained Notes), may declare the Note Balance of all the Outstanding Notes and all interest and principal accrued and unpaid
(if any) thereon and all other amounts due and payable under any Transaction Document to be due and payable immediately, and upon any
such declaration each Note will become and will be immediately due and payable and the Revolving Period with respect to such Series or
Class shall immediately terminate, anything in this Base Indenture, the related Indenture Supplement(s) or in the Notes to the
contrary notwithstanding. Such payments are subject to the allocation, deposits and payment sections of this Base Indenture and of the
related Indenture Supplement(s).

 

(b)           At
any time after such a declaration of acceleration has been made or an automatic acceleration has occurred with respect to the Notes of
any Series or Class and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee
as hereafter provided in this Article VIII, the Majority Noteholders of all Outstanding Notes, by written notice to the Issuer
and the Indenture Trustee, may rescind and annul such declaration and its consequences if:

 

(i)            the
Issuer has paid or deposited with the Indenture Trustee a sum sufficient to pay (A) all overdue installments of interest on such
Notes, (B) the principal of such Notes which has become due otherwise than by such declaration of acceleration, and interest thereon
at the rate or rates prescribed therefor by the terms of such Notes, to the extent that payment of such interest is lawful, (C) interest
upon overdue installments of interest at the rate or rates prescribed therefore by the terms of such Notes to the extent that payment
of such interest is lawful, and (D) all sums paid by the Indenture Trustee hereunder and the reasonable compensation, expenses and
disbursements of the Indenture Trustee or the bank serving as Indenture Trustee (in any of its capacities), their agents and counsel,
all other amounts due under Section 4.5; and

 

    72

     

    

 

(ii)           all
Events of Default, other than the nonpayment of the principal of such Notes which has become due solely by such acceleration, have been
cured or waived as provided in Section 8.14.

 

No such rescission will affect
any subsequent default or impair any right consequent thereon.

 

Section 8.3.           Collection
of Indebtedness and Suits for Enforcement by Indenture Trustee.

 

The Issuer covenants that
if:

 

(a)           the
Issuer defaults in the payment of interest on any Notes when such interest becomes due and payable, which default continues for a period
of two (2) Business Days following written notice from the Indenture Trustee of such default; or

 

(b)           the
Issuer defaults in the payment of the principal of any Series or Class of Notes on the Stated Maturity Date thereof; then

 

the Issuer will, upon demand
of the Indenture Trustee, pay (subject to the allocation provided in Section 4.5(a)(2) hereof and any related Indenture
Supplement) to the Indenture Trustee, for the benefit of the Noteholders of any such Notes, the whole amount then due and payable on any
such Notes for principal and interest, together with any Cumulative Interest Shortfall Amounts, unless otherwise specified in the applicable
Indenture Supplement, and in addition thereto, will pay such further amount as will be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and the bank serving as Indenture
Trustee (in any of its capacities), their agents and counsel and all other amounts due under Section 4.5.

 

If the Issuer fails to pay
such amounts forthwith upon such demand, the Indenture Trustee may, in its own name and as trustee of an express trust, institute a judicial
proceeding for the collection of the sums so due and unpaid, and may directly prosecute such proceeding to judgment or final decree, and
the Indenture Trustee may enforce the same against the Issuer or any other obligor upon the Notes and collect the money adjudged or decreed
to be payable in the manner provided by law and this Base Indenture.

 

Section 8.4.           Indenture
Trustee May File Proofs of Claim.

 

In case of the pendency of
any Insolvency Event or other similar proceeding or event relative to the Issuer or any other obligor upon the Notes or the property of
the Issuer or of such other obligor, the Indenture Trustee (irrespective of whether the principal of the Notes will then be due and payable
as therein expressed or by declaration or otherwise) will be entitled and empowered by intervention in such proceeding or otherwise:

 

(a)            to
file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such other
papers or documents as may be necessary and advisable in order to have the claims of the Indenture Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Indenture Trustee, its agents and counsel and all other amounts due
under Section 4.5) and of the Noteholders allowed in such judicial proceeding; and

 

    73

     

    

 

(b)            to
collect and receive any funds or other property payable or deliverable on any such claims and to distribute the same; and any receiver,
assignee, trustee, liquidator or other similar official in any such proceeding is hereby authorized by each Noteholder to make such payment
to the Indenture Trustee and the bank serving as Indenture Trustee (in all its capacities), and in the event that the Indenture Trustee
consents to the making of such payments directly to the Noteholders, to pay to the Indenture Trustee and the bank serving as Indenture
Trustee (in all its capacities) any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and the bank serving as Indenture Trustee (in all its capacities), their agents and counsel, and any other amounts due the Indenture
Trustee and the bank serving as Indenture Trustee (in all its capacities) under Section 4.5.

 

Nothing herein contained will
be deemed to authorize the Indenture Trustee to authorize or consent to or accept or adopt on behalf of any Noteholder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Noteholder thereof, or to authorize the Indenture Trustee
to vote in respect of the claim of any Noteholder in any such proceeding.

 

Section 8.5.           Indenture
Trustee May Enforce Claims Without Possession of Notes.

 

All rights of action and claims
under this Base Indenture or the Notes of any Series or Class are subject to the Acknowledgment Agreement and the Fannie Mae
Requirements and may be prosecuted and enforced by the Indenture Trustee, without the possession of any of the Notes of such Series or
Class or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Indenture Trustee,
will be brought in its own name as trustee of an express trust, and any recovery of judgment will, after provision for the payment of
the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its respective agents and counsel, be for
the ratable benefit of the Noteholders of the Notes of such Series or Class in respect of which such judgment has been recovered.

 

Section 8.6.           Application
of Money Collected.

 

Any money or other property
collected by the Indenture Trustee pursuant to this Article VIII will be applied in accordance with Section 4.5(a)(2),
at the Final Payment Date fixed by the Indenture Trustee and, in case of the payment of such money on account of principal, interest or
fees, upon presentation of the Notes of the related Series or Class and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid.

 

Section 8.7.           Sale
of Collateral Requires Consent of Noteholders.

 

Subject to the Acknowledgment
Agreement and the Fannie Mae Requirements, the Indenture Trustee shall not sell Collateral or cause the Issuer to sell Collateral following
any Event of Default, except with the written consent, or at the direction of, the Noteholders as set forth in Section 8.13;
provided, that the Indenture Trustee shall, subject to the consent of Fannie Mae, sell Collateral or cause the Issuer to sell Collateral
without prior consent of any of the Noteholders if an Event of Default under clauses (b), (c) or (q) of Section 8.1
occurs. Notwithstanding the foregoing, the consent of 100% of the Noteholders of the Outstanding Notes of each Series shall be required
for any sale that does not generate sufficient proceeds to pay the Note Balance of all such Notes plus all accrued and unpaid interest
and other amounts owed in respect of such Notes and the Transaction Documents. If such direction has been given by the Noteholders of
the requisite percentage of all Outstanding Notes, the Indenture Trustee shall, subject to the Acknowledgment Agreement and the Fannie
Mae Requirements and the terms of the Acknowledgment Agreement, cause the Issuer to sell Collateral pursuant to Section 8.15,
and shall provide notice of this to each Note Rating Agency of then Outstanding Notes.

 

    74

     

    

 

 

Section 8.8.       Limitation
on Suits.

 

No Noteholder will have any
right to institute any proceeding, judicial or otherwise, with respect to this Base Indenture or any Note, or for the appointment of a
receiver or trustee or similar official, or for any other remedy hereunder, unless:

 

(a)            such
Noteholder has previously given written notice to the Indenture Trustee of a continuing Event of Default with respect to Notes of such
Noteholder’s Notes’ Series or Class;

 

(b)           the
Noteholders of more than 50% of the Note Balance of the Outstanding Notes of each Series, measured by Voting Interests, have made written
request to the Indenture Trustee to institute proceedings in respect of such Event of Default in the name of the Indenture Trustee hereunder;

 

(c)            such
Noteholder or Noteholders have offered to the Indenture Trustee indemnity reasonably satisfactory to it against the costs, expenses and
liabilities to be incurred in compliance with such request; and

 

(d)           the
Indenture Trustee, for sixty (60) days after the Indenture Trustee has received such notice, request and offer of indemnity, has failed
to institute any such proceeding; it being understood and intended that no one or more Noteholders of Notes of such Series or Class will
have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Base Indenture or any Note to affect, disturb
or prejudice the rights of any other Noteholders of Notes, or to obtain or to seek to obtain priority or preference over any other such
Noteholders or to enforce any right under this Base Indenture or any Note, except in the manner herein provided and for the equal and
proportionate benefit of all the Noteholders of all Notes.

 

The rights set out in this Section 8.8
are further subject to Section 7.4(a).

 

    75

     

    

 

Section 8.9.       Limited
Recourse.

 

Notwithstanding any other
terms of this Base Indenture, the Notes, any other Transaction Documents or otherwise, the obligations of the Issuer under the Notes,
this Base Indenture 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 Base Indenture, none of the Noteholders, 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. Subject to the foregoing and to the terms of the applicable Indenture Supplement,
each Noteholder will, however, have the absolute and unconditional right to receive payment of all amounts due with respect to the Notes
pursuant and respect to the terms of the Indenture, which right shall not be impaired without the consent of each Noteholder and to initiate
suit for the enforcement of any such payment, which right shall not be impaired without the consent of such Noteholder. No recourse shall
be had for the payment of any amount owing in respect of the Notes or this Base Indenture or for any action or inaction of the Issuer
against any officer, director, employee, equity holder or organizer of the Issuer or any of their successors or assigns for any amounts
payable under the Notes or this Base Indenture. It is understood that the foregoing provisions of this Section 8.9 shall not
(i) 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, (ii) prevent recourse to the Guarantor under the PC Repo Guaranty or (iii) save as specifically provided
therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by the Notes or secured by this Base Indenture.
It is further understood that the foregoing provisions of this Section 8.9 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 Notes or this Base Indenture, 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 8.10.       Restoration
of Rights and Remedies.

 

If the Indenture Trustee or
any Noteholder has instituted any proceeding to enforce any right or remedy under this Base Indenture and such proceeding has been discontinued
or abandoned for any reason, then and in every such case the Issuer, the Indenture Trustee and the Noteholders will, subject to any determination
in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies
of the Indenture Trustee and the Noteholders will continue as though no such proceeding had been instituted.

 

Section 8.11.       Rights
and Remedies Cumulative.

 

No right or remedy herein
conferred upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and
every right and remedy will, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder
or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
will not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 

Section 8.12.       Delay
or Omission Not Waiver.

 

No delay or omission of the
Indenture Trustee or of any Noteholder to exercise any right or remedy accruing upon any Event of Default will impair any such right or
remedy or constitute a waiver of any such Event of Default or acquiescence therein. Every right and remedy given by this Article or
by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by
the Indenture Trustee or by the Noteholders, as the case may be.

 

    76

     

    

 

Section 8.13.       Control
by Noteholders.

 

Either 100% of the VFN Noteholders
or the Majority Noteholders of all Outstanding Notes will have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee with respect to
such Notes; provided that:

 

(a)            the
Indenture Trustee will have the right to decline to follow any such direction if the Indenture Trustee, being advised by counsel, determines
that the action so directed may violate applicable law or would conflict with this Base Indenture or if the Indenture Trustee in good
faith determines that the proceedings so directed would have a substantial likelihood of involving it in personal liability or be unjustly
prejudicial to the Noteholders not taking part in such direction, unless the Indenture Trustee has received indemnity satisfactory to
it from the Noteholders;

 

(b)           the
Indenture Trustee may take any other action permitted hereunder deemed proper by the Indenture Trustee which is not inconsistent with
such direction; and

 

(c)            to
the extent there are conflicting directions between 100% of the VFN Noteholders and the Majority Noteholders, the Indenture Trustee will
take its direction from 100% of the VFN Noteholders (excluding any Retained Notes).

 

The rights of the Noteholders
set out in this Section 8.13 are further subject to Section 7.4(a).

 

Section 8.14.       Waiver
of Past Defaults.

 

Together, the Majority Noteholders
of all Outstanding Notes that are not Variable Funding Notes, the Majority Noteholders for any Series of Variable Funding Notes Outstanding
and the Administrative Agent may on behalf of the Noteholders of all such Notes waive any past default hereunder and its consequences,
except a default not theretofore cured:

 

(a)            in
the payment of the principal of or interest on any Note, or

 

(b)           in
respect of a covenant or provision hereof which under Article XII cannot be modified or amended without the consent of the
Noteholder of each Outstanding Note.

 

Upon any such waiver, such
default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, for every purpose of this Base
Indenture; but no such waiver will extend to any subsequent or other default or impair any right consequent thereon.

 

Section 8.15.       Sale
of Trust Estate.

 

(a)           The
power to effect any Sale of any portion of the Trust Estate shall not be exhausted by any one or more Sales as to any portion of the Trust
Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate shall have been sold or all amounts payable on the
Notes and under this Base Indenture with respect thereto shall have been paid. The Indenture Trustee may from time to time postpone any
public Sale by public announcement made at the time and place of such Sale.

 

    77

     

    

 

(b)           Unless
the Majority Noteholders of all Outstanding Series have otherwise provided its written consent to the Indenture Trustee, at any public
Sale of all or any portion of the Trust Estate at which a minimum bid equal to or greater than all amounts due to the Indenture Trustee
hereunder and the entire amount which would be payable to the Noteholders in full payment thereof in accordance with Section 8.6,
on the Payment Date next succeeding the date of such sale, has not been received, the Indenture Trustee shall prevent such sale by bidding
an amount at least $1.00 more than the highest other bid in order to preserve the Trust Estate.

 

(c)            In
connection with a Sale of all or any portion of the Trust Estate:

 

(i)             any
of the Noteholders may bid for and purchase the property offered for Sale, and upon compliance with the terms of sale may hold, retain
and possess and dispose of such property, without further accountability;

 

(ii)            the
Indenture Trustee may bid for and acquire the property offered for Sale in connection with any Sale thereof;

 

(iii)           the
Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Trust
Estate in connection with a Sale thereof;

 

(iv)          the
Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuer to transfer and convey its interest in
any portion of the Trust Estate in connection with a Sale thereof, and to take all action necessary to effect such Sale; and

 

(v)           no
purchaser or transferee at such a Sale shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction
of any conditions precedent or see to the application of any monies.

 

(d)           Notwithstanding
anything to the contrary in this Base Indenture, and subject to the Acknowledgment Agreement and the Fannie Mae Requirements, if an Event
of Default has occurred and is continuing and the Notes have become due and payable or have been declared due and payable and such declaration
and its consequences have not been rescinded and annulled, any proceeds received by the Indenture Trustee with respect to a foreclosure,
sale or other realization resulting from a transfer of the assets of the Trust Estate shall be allocated in accordance with Section 4.5(a)(2) hereof.
The amount, if any, so allocated to the Issuer shall be paid by the Indenture Trustee to or to the order of the Issuer free and clear
of the Adverse Claim of this Base Indenture and the Noteholders shall have no claim or rights to the amount so allocated.

 

Section 8.16.       Undertaking
for Costs.

 

All parties to this Base Indenture
agree, and each Noteholder by its acceptance thereof will be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Base Indenture, or in any suit against the Indenture Trustee for any action
taken or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section will not apply to any suit instituted by the Indenture Trustee, to any suit instituted by any
Noteholder or group of Noteholders holding in the aggregate more than 25% of the Note Balance of the Outstanding Notes of each Series (measured
by Voting Interests) to which the suit relates, or to any suit instituted by any Noteholders for the enforcement of the payment of the
principal of or interest on any Note on or after the applicable Stated Maturity Date expressed in such Note.

 

    78

     

    

 

Section 8.17.       Waiver
of Stay or Extension Laws.

 

The Issuer covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or
the performance of this Base Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the
Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 

Section 8.18.       Notice
of Waivers.

 

Promptly (and in no event
later than two (2) Business Days following the occurrence thereof), after any waiver of an Event of Default pursuant to Section 4.12,
or any rescission or annulment of a declaration of acceleration pursuant to Section 8.2(b), or any waiver of past default
pursuant to Section 8.14, the Issuer will notify all related Note Rating Agencies and the Disposition Manager in writing.

 

Article IX

 

The Issuer

 

Section 9.1.       Representations
and Warranties of Issuer.

 

The Issuer hereby makes the
following representations and warranties for the benefit of the Servicer, the Indenture Trustee, the Disposition Manager and the Noteholders.
The representations shall be made as of the execution and delivery of this Base Indenture and of each Indenture Supplement, and as of
each Funding Date and as of each date of Grant and shall survive the Grant of a Security Interest in the Participation Certificates to
the Indenture Trustee.

 

(a)            Organization
and Good Standing. The Issuer is duly organized and validly existing as a statutory trust and is in good standing under the laws of
the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are currently owned
and such business is presently conducted. The Issuer has appointed the Administrator as the Issuer’s agent where notices and demands
to or upon the Issuer in respect of the Notes of this Base Indenture may be served.

 

    79

     

    

 

(b)           Power
and Authority. The Issuer has and will continue to have the power and authority to execute and deliver this Base Indenture and the
other Transaction Documents to which it is or will be a party, and to carry out their respective terms; the Issuer had and has had at
all relevant times and now has full power, authority and legal right to acquire, own, hold and Grant a Security Interest in the Trust
Estate and has duly authorized such Grant to the Indenture Trustee by all necessary action; and the execution, delivery and performance
by the Issuer of this Base Indenture and each of the other Transaction Documents to which it is a party has been duly authorized by all
necessary action of the Issuer.

 

(c)            Valid
Transfers; Binding Obligations. This Base Indenture creates a valid Grant of a Security Interest in the Participation Certificates
which has been validly perfected and is a first priority Security Interest under the UCC, and in such other portion of the Collateral
as to which a Security Interest may be granted under the UCC, which security interest is enforceable against creditors of and purchasers
from the Issuer, subject to applicable law. Each of the Transaction Documents to which the Issuer is a party constitutes a legal, valid
and binding obligation of the Issuer enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization or other similar laws affecting creditors’ rights generally or by general equity principles.

 

(d)           No
Violation. The execution and delivery by the Issuer of this Base Indenture and each other Transaction Document to which it is a party
and the consummation of the transactions contemplated by this Base Indenture and the other Transaction Documents and the fulfillment of
the terms of this Base Indenture and the other Transaction Documents do not conflict with, result in any breach of any of the terms or
provisions of, or constitute (with or without notice or lapse of time or both) a default under the Organizational Documents of the Issuer
or any indenture, agreement or other material instrument to which the Issuer is a party or by which it is bound, or result in the creation
or imposition of any Adverse Claim upon any of its properties pursuant to the terms of any such indenture, agreement or other instrument
(other than this Base Indenture), or violate any law, order, judgment, decree, writ, injunction, award, determination, rule or regulation
applicable to the Issuer of any court or of any federal or state regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Issuer or its properties, which breach, default, conflict, Adverse Claim or violation could reasonably be
expected to have a material Adverse Effect.

 

(e)            No
Proceedings. There is no action, suit or proceeding before or by any court or governmental agency or body, domestic or foreign, now
pending, or to the Issuer’s knowledge, threatened, against or affecting the Issuer: (i) asserting the invalidity of this Base
Indenture, the Notes or any of the other Transaction Documents to which the Issuer is a party, (ii) seeking to prevent the issuance
of the Notes or the consummation of any of the transactions contemplated by this Base Indenture, or any of the other Transaction Documents,
(iii) seeking any determination or ruling which could reasonably be expected to have a material Adverse Effect or could reasonably
be expected to materially and adversely affect the condition (financial or otherwise), business or operations of the Issuer, or (iv) relating
to the Issuer and which could reasonably be expected to adversely affect the United States federal income tax attributes of the Notes.

 

(f)            No
Subsidiaries. The Issuer has no subsidiaries.

 

    80

     

    

 

(g)           All
Tax Returns True, Correct and Timely Filed. All tax returns required to be filed by the Issuer in any jurisdiction have in fact been
filed and all taxes, assessments, fees and other governmental charges upon the Issuer or upon any of its properties, and all income of
franchises, shown to be due and payable on such returns have been paid except for any such taxes, assessments, fees and charges the amount,
applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the
Issuer had established adequate reserves in accordance with GAAP. All such tax returns were true and correct in all material respects
and the Issuer knows of no proposed additional tax assessment against it that could reasonably be expected to have a material adverse
effect upon the ability of the Issuer to perform its obligations hereunder nor of any basis therefor. The provisions for taxes on the
books of the Issuer are in accordance with GAAP.

 

(h)           No
Restriction on Issuer Affecting its Business. The Issuer is not a party to any contract or agreement, or subject to any charter or
other restriction, which materially and adversely affects its business, and the Issuer has not agreed or consented to cause any of its
assets or properties to become subject to any Adverse Claim other than the Security Interest or any Permitted Liens.

 

(i)            Title
to Participation Certificates. As represented by PLS in the PC Repurchase Agreement, immediately prior to the Grant thereof to the
Indenture Trustee as contemplated by this Base Indenture, subject to the Acknowledgment Agreement and the Fannie Mae Requirements with
respect thereto, the Issuer had good and marketable title to each Participation Certificate, free and clear of all Adverse Claims other
than any Permitted Liens and rights of others.

 

(j)             Perfection
of Security Interest. All filings and recordings that are necessary to perfect the interest of the Issuer in the Participation Certificates
and such other portion of the Trust Estate as to which a sale or security interest may be perfected by filing under the UCC, have been
accomplished and are in full force and effect. All filings and recordings against the Issuer required to perfect the Security Interest
of the Indenture Trustee in such Participation Certificates and such other portion of the Trust Estate as to which a Security Interest
may be perfected by filing under the UCC, have been accomplished and are in full force and effect, and all such filings and recordings
against the Issuer include the legends set forth as clauses (i) through (iii) of the fourth full paragraph of
the Granting Clause. Subject to the rights of Fannie Mae with respect thereto, other than the Security Interest granted to the
Indenture Trustee pursuant to this Base Indenture, the Issuer has not pledged, assigned, sold, granted a Security Interest in, or otherwise
conveyed any of the Participation Certificates or any other Collateral. The Issuer has not authorized the filing of and is not aware of
any financing statement filed against the Issuer that includes a description of collateral covering the Participation Certificates other
than (1) any financing statement related to the Security Interest granted to the Indenture Trustee hereunder or (2) that has
been terminated.

 

(k)            Notes
Authorized, Executed, Authenticated, Validly Issued and Outstanding. The Notes have been duly and validly authorized and, when duly
and validly executed and authenticated by the Indenture Trustee in accordance with the terms of this Base Indenture and delivered to and
paid for by each purchaser as provided herein, will be validly issued and outstanding and entitled to the benefits hereof.

 

    81

     

    

 

(l)             Location

Section 9.2.       Liability
of Issuer; Indemnities.

 

(a)            Obligations.
The Issuer shall be liable in accordance with this Base Indenture only to the extent of the obligations in this Base Indenture specifically
undertaken by the Issuer in such capacity under this Base Indenture and shall have no other obligations or liabilities hereunder. The
Issuer shall indemnify, defend and hold harmless the Indenture Trustee (in all its capacities), the Calculation Agent, the Paying Agent,
the Securities Intermediary, the Note Registrar, the Disposition Manager, the Noteholders (as applicable, with respect to the related
Series of Notes) and the Trust Estate (each an “Issuer Indemnified Party”) from and against any taxes that
may at any time be asserted against the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities Intermediary, the Note
Registrar, the Disposition Manager or the Trust Estate with respect to the transactions contemplated in this Base Indenture or any of
the other Transaction Documents, including any sales, gross receipts, general corporation, tangible or intangible personal property, privilege
or license taxes (but not including any taxes asserted with respect to, and as of the date of, the transfer of the Participation Certificates
to the Trust Estate, the issuance and original sale of the Notes of any Class, or asserted with respect to ownership of the Participation
Certificates, or federal, state or local income or franchise taxes or any other tax, or other income taxes arising out of payments on
the Notes of any Class, or any interest or penalties with respect thereto or arising from a failure to comply therewith) and costs and
expenses in defending against the same and in connection with the Issuer Indemnified Parties’ enforcement of any rights hereunder
or under any Transaction Document, except that in no event shall the Issuer be required to indemnify any Issuer Indemnified Party if the
indemnification obligation under this Section 9.2(a) to such Issuer Indemnified Party is the result of a violation of
law, gross negligence or willful misconduct by such Issuer Indemnified Party.

 

    83

     

    

 

(b)           Notification
and Defense. Promptly after any Issuer Indemnified Party shall have been served with the summons or other first legal process or shall
have received written notice of the threat of a claim in respect of which a claim for indemnity may be made against the Issuer under this
Section 9.2, the Issuer Indemnified Party shall notify the Issuer and the Administrator in writing of the service of such
summons, other legal process or written notice, giving information therein as to the nature and basis of the claim, but failure so to
notify the Issuer shall not relieve the Issuer from any liability which it may have hereunder or otherwise, except to the extent that
the Issuer is prejudiced by such failure so to notify the Issuer. The Issuer will be entitled, at its own expense, to participate in the
defense of any such claim or action and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory
to such Issuer Indemnified Party, and, after notice from the Issuer to such Issuer Indemnified Party that the Issuer wishes to assume
the defense of any such action, the Issuer will not be liable to such Issuer Indemnified Party under this Section 9.2 for
any legal or other expenses subsequently incurred by such Issuer Indemnified Party in connection with the defense of any such action unless
(i) the defendants in any such action include both the Issuer Indemnified Party and the Issuer, and the Issuer Indemnified Party
(upon the advice of counsel) shall have reasonably concluded that there may be legal defenses available to it that are different from
or additional to those available to the Issuer, or one or more Issuer Indemnified Parties, and which in the reasonable judgment of such
counsel are sufficient to create a conflict of interest for the same counsel to represent both the Issuer and such Issuer Indemnified
Party, (ii) the Issuer shall not have employed counsel reasonably satisfactory to the Issuer Indemnified Party to represent the Issuer
Indemnified Party within a reasonable time after notice of commencement of the action, or (iii) the Issuer has authorized the employment
of counsel for the Issuer Indemnified Party at the expense of the Issuer; then, in any such event, such Issuer Indemnified Party shall
have the right to employ its own counsel in such action, and the reasonable fees and expenses of such counsel shall be borne by the Issuer;
provided, however, that the Issuer shall not in connection with any such action or separate but substantially similar or
related actions arising out of the same general allegations or circumstances, be liable for any fees and expenses of more than one firm
of attorneys at any time for all Issuer Indemnified Parties. Each Issuer Indemnified Party, as a condition of the indemnity agreement
contained herein, shall use its commercially reasonable efforts to cooperate with the Issuer in the defense of any such action or claim.
The Issuer shall not, without the prior written consent of any Issuer Indemnified Party, effect any settlement of any pending or threatened
proceeding in respect of which such Issuer Indemnified Party is or could have been a party and indemnity could have been sought hereunder
by such Issuer Indemnified Party, unless such settlement includes an unconditional release of such Issuer Indemnified Party from all liability
on claims that are the subject matter of such proceeding or threatened proceeding.

 

(c)            Expenses.
Indemnification under this Section shall include, without limitation, reasonable and customary out-of-pocket fees and expenses of
counsel and expenses of litigation. If the Issuer has made any indemnity payments pursuant to this Section and the recipient thereafter
collects any of such amounts from others, the recipient shall promptly repay such amounts collected to the Issuer, without interest.

 

(d)           Survival.
The provisions of this Section 9.2 shall survive the termination of this Base Indenture.

 

    84

     

    

 

Section 9.3.       Merger
or Consolidation, or Assumption of the Obligations, of the Issuer.

 

Any Person (a) into which
the Issuer may be merged or consolidated, (b) which may result from any merger, conversion or consolidation to which the Issuer shall
be a party, or (c) which may succeed to all or substantially all of the business or assets of the Issuer, which Person in any of
the foregoing cases executes an agreement of assumption to perform every obligation of the Issuer under this Base Indenture, shall be
the successor to the Issuer under this Base Indenture without the execution or filing of any document or any further act on the part of
any of the parties to this Base Indenture, except that if the Issuer in any of the foregoing cases is not the surviving entity, then the
surviving entity shall execute an agreement of assumption to perform every obligation of the Issuer under the Transaction Documents, and
the surviving entity shall have taken all actions necessary or reasonably requested by the Issuer, the Majority Noteholders of all Outstanding
Notes or the Indenture Trustee to amend its existing financing statements and continuation statements, and file additional financing statements
and to take any other steps reasonably requested by the Issuer, the Majority Noteholders of all Outstanding Notes or the Indenture Trustee
to further perfect or evidence the rights, claims or security interests of the Issuer, the Noteholders or the Indenture Trustee under
any of the Transaction Documents. The Issuer (i) shall provide notice of any merger, consolidation or succession pursuant to this
Section 9.3 to each Note Rating Agency that has rated any then-Outstanding Notes, the Indenture Trustee and the Noteholders,
(ii) for so long as the Notes are Outstanding, (1) shall receive from each Note Rating Agency rating Outstanding Notes a letter
to the effect that such merger, consolidation or succession will not result in a qualification, downgrading or withdrawal of the then
current ratings assigned by such Note Rating Agency to any Outstanding Notes or (2) if the Administrator and the Administrative Agents
determine in their reasonable judgment that an applicable Note Rating Agency no longer provides such letters as described in the foregoing
clause (1), (a) the Administrator shall provide notice of such new merger, consolidation or succession to the related Note
Rating Agency and (b) each Administrative Agent shall have provided its prior written consent to such merger, consolidation or succession;
provided, that the Issuer provides an Issuer Certificate to the effect that any such merger, consolidation or succession will not
have a material Adverse Effect on the Outstanding Notes, (iii) shall obtain an Opinion of Counsel addressed to the Indenture Trustee
and reasonably satisfactory to the Indenture Trustee, that such merger, consolidation or succession complies with the terms hereof and
one or more Opinions of Counsel updating or restating all opinions delivered on the date of this Base Indenture with respect to corporate
matters, enforceability of Transaction Documents against the Issuer, and the grant by the Issuer of a valid security interest in the Participation
Certificates to the Indenture Trustee and the perfection of such security interest and related matters, (iv) shall receive from the
Majority Noteholders of all Outstanding Notes their prior written consent to such merger, consolidation or succession, absent which consent,
which may not be unreasonably withheld or delayed, the Issuer shall not become a party to such merger, consolidation or succession and
(v) shall obtain an Issuer Tax Opinion.

 

    85

May Not Own Notes.

 

The Issuer may not become
the owner or pledgee of one or more of the Notes (other than any Retained Note). Any Person Controlling, Controlled by or under common
Control with the Issuer may, in its individual or any other capacity, become the owner or pledgee of one or more Notes with the same rights
as it would have if it were not an Affiliate of the Issuer, except as otherwise specifically provided in the definition of the term “Noteholder.”
The Notes so owned by or pledged to such Controlling, Controlled or commonly Controlled Person shall have an equal and proportionate benefit
under the provisions of this Base Indenture, without preference, priority or distinction as among any of the Notes, except as set forth
herein with respect to, among other things, rights to vote, consent or give directions to the Indenture Trustee as a Noteholder.

approvals, permits, registrations or qualifications in all jurisdictions in which its ownership or lease of property or the conduct of
its business requires such licenses, approvals, registrations or qualifications, except for failures to maintain any such licenses, approvals,
registrations or qualifications which, individually or in the aggregate, would not have a material Adverse Effect.

 

(c)            Compliance
with Laws. The Issuer hereby covenants to comply in all material respects with all applicable laws, rules and regulations and
orders of any governmental authority, the noncompliance with which would have a material Adverse Effect or a material adverse effect on
the business, financial condition or results of operations of the Issuer.

 

(d)           Payment
of Taxes. The Issuer hereby covenants to pay and discharge promptly or cause to be paid and discharged promptly all taxes, assessments
and governmental charges or levies imposed upon the Issuer or upon its income and profits, or upon any of its property or any part thereof,
before the same shall become in default, provided that the Issuer shall not be required to pay and discharge any such tax, assessment,
charge or levy so long as the validity or amount thereof shall be contested in good faith by appropriate proceedings and the Issuer shall
have set aside on its books adequate reserves with respect to any such tax, assessment, charge or levy so contested.

 

    86

     

    

 

(e)            Investments.

acquired under the PC Repurchase Agreement.

 

(f)            Keeping
Records and Books of Account. The Issuer hereby covenants and agrees to maintain and implement administrative and operating procedures

thereof) and keep and maintain, all documents, books, records and other information reasonably necessary or advisable for the collection
of all Participation Certificates (including records adequate to permit the daily identification of all collections with respect to, and
adjustments of amounts payable under, each Participation Certificate). The Administrator shall ensure compliance with this Section 9.5(f).

 

(g)           Employee

(h)           No
Release. The Issuer shall not take any action and shall use its best efforts not to permit any action to be taken by others that would
release any Person from any of such Person’s covenants or obligations under any Transaction Document, Fannie Mae Lender Contract
or other document, instrument or agreement included in the Trust Estate, or which would result in the amendment, hypothecation, subordination,
termination or discharge of, or impair the validity or effectiveness of, any such document, instrument or agreement.

 

(i)             Separate
Identity. The Issuer acknowledges that the Secured Parties are entering into the transactions contemplated by this Base Indenture
in reliance upon the Issuer’s identity as a legal entity that is separate from the Administrator or the Servicer (each, a “Facility
Entity”). Therefore, from and after the date of execution and delivery of this Base Indenture, the Issuer shall take all
reasonable steps to maintain the Issuer’s identity as a separate legal entity and to make it manifest to third parties that the
Issuer is an entity with assets and liabilities distinct from those of each Facility Entity and not a division of a Facility Entity.

 

(j)             Compliance
with and Enforcement of Transaction Documents. The Issuer hereby covenants and agrees to comply in all respects with the terms of,

Noteholders of all Outstanding Notes, maintain all such Transaction Documents in full force and effect and make to the parties thereto
such reasonable demands and requests for information and reports or for action as the Issuer is entitled to make thereunder and as may
be from time to time reasonably requested by the Indenture Trustee.

releases specifically permitted hereunder, not to sell, assign (by operation of law or otherwise) or otherwise dispose of, or create or
suffer to exist, any Adverse Claim (other than the Security Interest created hereby or any Permitted Liens) upon or with respect to, any
Participation Certificate or Trust Property, or any interest in either thereof, or upon or with respect to any Trust Account, or assign
any right to receive income in respect thereof. The Issuer shall promptly, but in no event later than two (2) Business Days after
a Responsible Officer has obtained actual knowledge thereof, notify the Indenture Trustee of the existence of any Adverse Claim on any
Participation Certificate or Trust Estate, and the Issuer shall defend the right, title and interest of each of the Issuer and the Indenture
Trustee in, to and under the Participation Certificates and Trust Estate, against all claims of third parties.

 

(l)            No
Change in Business. The Issuer covenants that it shall not make any change in the character of its business.

 

(m)          No
Change in Name, etc.; Preservation of Security Interests. The Issuer covenants that it shall not make any change to its company
name, or use any trade names, fictitious names, assumed names or “doing business as” names. The Issuer will from time to time,
at its own expense, execute and file such additional financing statements (including continuation statements) as may be necessary to ensure
that at any time, the interest of the Issuer in all of the Participation Certificates and such other portion of the Trust Estate as to
which a sale or Security Interest may be perfected by filing under the UCC, and the Security Interest of the Indenture Trustee in all
of the Participation Certificates and such other portion of the Trust Estate as to which a Security Interest may be perfected by filing
under the UCC, are fully protected.

 

(n)           No
Institution of Insolvency Proceedings. The Issuer covenants that it shall not institute Insolvency Proceedings with respect to the
Issuer or any Affiliate thereof or consent to the institution of Insolvency Proceedings against the Issuer or any Affiliate thereof or

to the Indenture Trustee an instrument in which such Paying Agent shall agree with the Indenture Trustee, subject to the provisions of
this Section, that such Paying Agent shall:

all sums held by it in respect of payments on Notes in trust for the benefit of the Noteholders entitled thereto until such sums shall
be paid to such Persons or otherwise disposed of as herein provided;

any time during the continuance of any such default, upon the written request of the Indenture Trustee, forthwith pay to the Indenture
Trustee all sums so held in trust by such Paying Agent.

obtaining the satisfaction and discharge of this Base Indenture or for any other purpose, pay, or direct any Paying Agent to pay, to the
Indenture Trustee all sums held in trust by such Paying Agent, such sums to be held by the Indenture Trustee upon the same trusts as those
upon which such sums were held by such Paying Agent; and, upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

 

(p)           Protection

any of the Participation Certificates or, where appropriate, any Security Interest in the Trust Estate and the proceeds thereof;

 

(v)           promptly
to amend, or to cause to be amended, as necessary, any filings or recordings against the Issuer relating to the Grant necessary to conform
to the requirements of Fannie Mae, including any legend required by Fannie Mae to be included in such filings or recordings; or

 

(vi)          preserve
and defend title to the Trust Estate and the rights of the Indenture Trustee and the Noteholders therein against the claims of all persons
and parties.

with Effectuating a Release. If any filing or recordings against the Issuer have been made relating to the Grant, within five (5) Business
Days after the earliest of any of the following dates or events that occur: (i) the effective date of any transfer of Issuer responsibility
pursuant to the Acknowledgment Agreement; (ii) the date on which the Secured Party receives notice from Fannie Mae of any termination
of Secured Party’s or Servicer’s rights under the Acknowledgment Agreement, or otherwise; or (iii) the date on which
Secured Party receives notice of the termination by Fannie Mae of Servicer’s redemption, equitable, legal or other right, title
or interest in the Subject Mortgages, then the Issuer shall, or shall cause to be filed for recording, in the appropriate recording office,
a fully and complete release of such security interest, and of any other right, title or interest of Secured Party in the Subject Mortgages,
and shall deliver to Fannie Mae written confirmation of such filing. Notwithstanding the foregoing, if the Issuer believes the Secured
Party’s Security Interest is being challenged or is likely to be challenged by anyone other than Fannie Mae, then the Issuer may
request that Fannie Mae agree to a deferral of the filings required by this subsection, which deferral shall be granted at the sole discretion
of Fannie Mae.

 

(v)           Issuer
Tax Opinion. No undertaking that would cause a Retained Note to become issued and outstanding for United States federal income tax
purposes will be permitted without the delivery of an Issuer Tax Opinion.

and as of the date of each Grant of Participation Certificates to the Indenture Trustee pursuant to this Base Indenture.

 

(a)            Organization
and Good Standing. PLS is a limited liability company, duly organized, validly existing and in good standing under the laws of the
State of Delaware. PLS, as Servicer, is duly qualified to do business and is in good standing (or is exempt from such requirements) and
has obtained all necessary licenses and approvals in each jurisdiction in which the failure so to qualify, or to obtain such licenses
or approvals, would have a material Adverse Effect.

 

(b)           Power
and Authority; Binding Obligation. PLS has the power and authority to make, execute, deliver and perform its obligations under this
Base Indenture and any related Indenture Supplement and each other Transaction Document to which it is a party and all of the transactions
contemplated hereunder and thereunder, and has taken all necessary corporate action to authorize the execution, delivery and performance
of this Base Indenture and each Indenture Supplement and each other Transaction Document to which it is a party; this Base Indenture and
each Indenture Supplement and each other Transaction Document to which it is a party constitutes a legal, valid and binding obligation
of PLS, enforceable against PLS in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect affecting the enforcement of creditors’ rights in general
and except as such enforceability may be limited by general principles of equity (whether considered in a proceeding at law or in equity)
or by public policy with respect to indemnification under applicable securities laws.

 

    90

     

    

 

(c)           No
Violation. The execution and delivery of this Base Indenture and each Indenture Supplement and each other Transaction Document to
which it is a party by PLS and its performance of its obligations under this Base Indenture and each Indenture Supplement and each other
Transaction Document to which it is a party will not (i) violate PLS’s certificate of formation, operating agreement or other
organizational documents or (ii) constitute a default (or an event which, with notice or lapse of time, or both, would constitute
a default) under, or result in the breach of, any material contract, agreement or other instrument to which PLS is a party or which may
be applicable to PLS or any of its assets, or any and all instruments, agreements, invoices or other writings which give rise to or otherwise

the Disposition Manager, the Trust Estate, the Owner Trustee and the Noteholders (as applicable, with respect to the related Series of

(b)            Notification
and Defense. Promptly after any Indemnified Party shall have been served with the summons or other first legal process or shall have
received written notice of the threat of a claim in respect of which a claim for indemnity may be made against PLS under this Section 10.4,
the Indemnified Party shall notify the Indemnifying Party in writing of the service of such summons, other legal process or written notice,
giving information therein as to the nature and basis of the claim, but failure so to notify the Indemnifying Party shall not relieve
the Indemnifying Party from any liability which it may have hereunder or otherwise, except to the extent that the Indemnifying Party is
prejudiced by such failure so to notify the Indemnifying Party. The Indemnifying Party will be entitled, at its own expense, to participate
in the defense of any such claim or action and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified Party that the Indemnifying
Party wishes to assume the defense of any such action, the Indemnifying Party will not be liable to such Indemnified Party under this
Section 10.4 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense
of any such action unless (i) the defendants in any such action include both the Indemnified Party and the Indemnifying Party, and
the Indemnified Party (upon the advice of counsel) shall have reasonably concluded that there may be legal defenses available to it that
are different from or additional to those available to the Indemnifying Party, or one or more Indemnified Parties, and which in the reasonable
judgment of such counsel are sufficient to create a conflict of interest for the same counsel to represent both the Indemnifying Party
and such Indemnified Party, (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified
Party to represent the Indemnified Party within a reasonable time after notice of commencement of the action, or (iii) the Indemnifying
Party has authorized the employment of counsel for the Indemnified Party at the expense of the Indemnifying Party; then, in any such event,
such Indemnified Party shall have the right to employ its own counsel in such action, and the reasonable fees and expenses of such counsel
shall be borne by the Indemnifying Party; provided, however, that the Indemnifying Party shall not in connection with any

consolidation or conversion (1) PLS shall have provided to the Indenture Trustee and the Noteholders a letter from each Note Rating
Agency that rated Outstanding Notes indicating that such merger, consolidation or conversion will not result in the qualification, reduction
or withdrawal of the then current ratings of the Outstanding Notes or (2) if the Administrator and the Administrative Agents determine
in their reasonable judgment that an applicable Note Rating Agency no longer provides such letters as described in the foregoing clause
(1), (a) the Administrator shall provide notice of such merger, consolidation or conversion to the related Note Rating Agency
and (b) each Administrative Agent shall have provided its prior written consent to merger, consolidation or conversion; provided,
that the Issuer provides an Issuer Certificate to the effect that any such merger, consolidation or conversion will not have a material
Adverse Effect on the Outstanding Notes, and (ii) prior to any such merger, consolidation or conversion the Administrator shall have
delivered to the Indenture Trustee an Opinion of Counsel to the effect that such merger, consolidation or conversion complies with the
terms of this Base Indenture and one or more Opinions of Counsel updating or restating all opinions delivered on the date of this Base
Indenture with respect to corporate matters and the enforceability of Transaction Documents against PLS true sale as to the transfers

specified in clauses (i) and (ii) above shall not apply to any transaction (i) in which an Affiliate
of PLS assumes the obligations of PLS and otherwise satisfies the eligibility criteria applicable to the Servicer under the Fannie Mae
Lender Contracts or (ii) in which an Affiliate of PLS is merged into or is otherwise combined with PLS and PLS is the sole survivor
of such merger or other combination. PLS shall provide notice of any merger, consolidation or succession pursuant to this Section to
the Indenture Trustee, the Noteholders and each Note Rating Agency.

Article XI

 

The Indenture Trustee

 

Section 11.1.Certain
Duties and Responsibilities.

 

(a)            The
Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Base Indenture with respect
to the Notes, and no implied covenants, duties (including fiduciary duties) or obligations will be read into this Base Indenture against
the Indenture Trustee.

 

(b)            In
the absence of bad faith on its part, the Indenture Trustee may, with respect to Notes, conclusively rely upon certificates or opinions
furnished to the Indenture Trustee and conforming to the requirements of this Base Indenture, as to the truth of the statements and the
correctness of the opinions expressed therein; but in the case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Indenture Trustee, the Indenture Trustee will be under a duty to examine the same to determine
whether or not they conform on their face to the requirements of this Base Indenture but need not confirm or investigate the accuracy
of any mathematical calculations or other facts stated therein.

 

(c)            If
an Event of Default has occurred and is continuing, with respect to the Notes of which a Responsible Officer of the Indenture Trustee
has been given written notice in the manner set forth in this Indenture or of which a Responsible Officer of the Indenture Trustee has
actual knowledge, the Indenture Trustee will exercise such of the rights and powers vested in it by this Base Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs; provided that the foregoing shall not be deemed to require the Indenture Trustee to take any action, or have any liability
for the failure to take any action, where the terms of this Base Indenture or any Supplement provide that the Indenture Trustee only takes
action at the direction of a certain percentage of the Noteholders or other Person or if the Indenture Trustee is permitted to refrain
from taking action unless it has been provided with adequate indemnity.

 

(d)            No
provision of this Base Indenture will be construed to relieve the Indenture Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

 

    	 	102	 

     

    

 

(i)            this
subsection (d) will not be construed to limit the effect of subsection (a) of this Section 11.1;

 

(ii)           the
Indenture Trustee will not be liable for any error of judgment made in good faith by an Indenture Trustee Authorized Officer, unless it
will be proved that the Indenture Trustee was negligent in ascertaining the pertinent facts;

 

(iii)           the
Indenture Trustee will not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the
direction of the Majority Noteholders or the Administrative Agent relating to the time, method and place of conducting any proceeding
for any remedy available to the Indenture Trustee, or exercising any trust or power conferred upon the Indenture Trustee, under this Base
Indenture with respect to the Notes of any Class, to the extent consistent with Sections 8.7 and 8.8;

 

(iv)           no
provision of this Base Indenture will require the Indenture Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it has reasonable grounds for
believing that repayment of such funds or indemnity satisfactory to the Indenture Trustee against such risk or liability is not reasonably
assured to it;

 

(v)            whether
or not therein expressly so provided, every provision of this Base Indenture relating to the conduct or affecting the liability of or
affording protection to the Indenture Trustee will be subject to the provisions of this Section; and

 

(vi)            the
Indenture Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the
direction of the Issuer or of Noteholders, as applicable, in accordance with the terms of this Indenture, relating to the time, method
or place of conducting any proceeding for any remedy available to the Indenture Trustee or with respect to the exercise of any trust or
power conferred upon such party under this Indenture or with respect to the Notes.

 

(e)            Upon
the occurrence of an Event of Default under the PC Repurchase Agreement, the Indenture Trustee may (and at the direction of the Administrative
Agent or the Series Required Noteholders) send an Activation Notice to the Account Bank pursuant to which the Indenture Trustee shall
exercise its control over the Dedicated Account, as applicable.

 

Section 11.2.Notice
of Defaults.

 

Except as otherwise provided
in Section 3.3(b), within ninety (90) days after the occurrence of any Event of Default hereunder,

 

(a)            the
Indenture Trustee will transmit by mail to all registered Noteholders, as their names and addresses appear in the Note Register, notice
of such default hereunder known to the Indenture Trustee, and

 

(b)            the
Indenture Trustee will give prompt written notification thereof to each Note Rating Agency, unless such default shall have been cured
or waived; provided, however, that, except in the case of a default in the payment of the principal of or interest on any
Note of any Series or Class, the Indenture Trustee will be protected in withholding such notice if and so long as an Indenture Trustee
Responsible Officer in good faith determines that the withholding of such notice is in the interests of the Noteholders of such Series or
Class. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default.

 

    	 	103

(a)            The
Servicer hereby irrevocably constitutes and appoints the Indenture Trustee and any officer or agent thereof, during the continuation of
an Event of Default, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority
in the place and stead of the Servicer and in the name of the Servicer, for the purpose of carrying out the terms of this Base Indenture

(1)            to
take possession of and endorse and collect any wired funds, checks, drafts, notes, acceptances or other instruments for the payment of
monies due under any Participation Certificates Granted by the Issuer to the Indenture Trustee from the Obligors on underlying Mortgage
Loans or the Servicer, as the case may be;

file any claim or proceeding in any court of law or equity or take any other action otherwise deemed appropriate by the Indenture Trustee

(4)            to

at the Indenture Trustee’s option and at the expense of the Issuer, at any time, or from time to time, all acts and things which
the Indenture Trustee deems necessary to protect, preserve or realize upon the Participation Certificate Granted by the Issuer or the
Trust Estate and the Indenture Trustee’s and the Issuer’s respective security interests and ownership interests therein and
to effect the intent of this Base Indenture, all as fully and effectively as the Issuer might do;

 

    	 	108	 

     

    

 

(7)            to
perform or cause to be performed, the Servicer’s obligations under the Fannie Mae Lender Contract to the extent permitted by the
Acknowledgment Agreement;

 

(8)            upon
and after the occurrence of a default by the Servicer under the Fannie Mae Lender Contract, the Servicer also authorizes the Indenture
Trustee, or other party appointed by the Indenture Trustee, to have on site access to the Servicer’s operation sites, sufficient
for the Administrative Agent or other party appointed by it, to begin the process of transferring the portfolio to a “Standby Issuer”
as required pursuant to the Acknowledgment Agreement;

 

(9)            the
Servicer also authorizes the Administrative Agent, at any time and from time to time, to execute, in connection with the sale provided
for in Section 8.15 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the
Collateral; provided that the exercise of such powers are in accordance with the Acknowledgment Agreement; and

 

(10)            the
powers conferred on the Indenture Trustee are solely to protect the Noteholders’ interest in the Collateral and shall not impose
any duty upon the Indenture Trustee to exercise any such powers.

Indenture Trustee shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither
the Indenture Trustee nor any of its officers, directors, or employees shall be responsible to the Issuer for any act or failure to act
hereunder; provided, that the Indenture Trustee shall exercise such powers only in accordance with the Acknowledgment Agreement.
Nothing contained herein shall in any way be deemed to be a grant of power or authority to the Indenture Trustee or any officer or agent
thereof to take any of the actions described in this paragraph with respect to any underlying Obligor under any Portfolio Mortgage Loan.

 

Section 11.6.Money
Held in Trust.

 

The Indenture Trustee will
be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Issuer.

 

Section 11.7.Compensation
and Reimbursement, Limit on Compensation, Reimbursement and Indemnity.

 

Except as otherwise provided
in this Base Indenture:

as compensation for its services (in all capacities hereunder).

 

(b)            The
Indenture Trustee (including in all of its capacities) shall be indemnified and held harmless by the Trust Estate as set forth in Section 4.5
and Section 8.6, and shall be secondarily indemnified and held harmless by the Administrator for, from and against, as the
case may be, any loss, liability or expense incurred without negligence or willful misconduct on its part, arising out of, or in connection
with, the acceptance and administration of the Trust Estate, including the costs and expenses (including reasonable legal fees and expenses)
of defending itself against any claim in connection with the exercise or performance of any of its powers or duties under this Base Indenture,
provided that:

 

    	 	109	 

     

    

 

(i)            with
respect to any such claim, the Indenture Trustee shall have given the Administrator written notice thereof promptly after a Responsible
Officer of the Indenture Trustee shall have actual knowledge thereof; provided, however that failure to give such written
notice shall not affect the Trust Estate’s or the Administrator’s obligation to indemnify the Indenture Trustee, unless such
failure materially prejudices the Trust Estate’s or the Administrator’s rights;

 

(ii)            the
Administrator may, at its option, assume the defense of any such claim using counsel reasonably satisfactory to the Indenture Trustee;
and

 

(iii)            notwithstanding
anything in this Base Indenture to the contrary, the Administrator shall not be liable for settlement of any claim by the Indenture Trustee,
as the case may be, entered into without the prior consent of the Administrator, which consent shall not be unreasonably withheld.

 

Notwithstanding the foregoing,
in no event shall the Trust Estate or the Administrator be required to indemnify the Indenture Trustee if the indemnification obligation
under this Section 11.7 is the result of gross negligence or willful misconduct by the Indenture Trustee.

 

No termination of this Base
Indenture, or the resignation or removal of the Indenture Trustee, shall affect the obligations created by this Section 11.7(b) of
the Administrator to indemnify the Indenture Trustee under the conditions and to the extent set forth herein.

 

Notwithstanding the foregoing,
the indemnification provided in this Section 11.7(b) with respect to the Administrator shall not pertain to any loss,
liability or expense of the Indenture Trustee, including the costs and expenses of defending itself against any claim, incurred in connection
with any actions taken by the Indenture Trustee at the direction of the Noteholders pursuant to the terms of this Base Indenture.

 

The Indenture Trustee agrees
fully to perform its duties under this Base Indenture notwithstanding its failure to receive any payments of Indenture Trustee Fees pursuant
to this Section 11.7(b) subject to its rights to resign in accordance with the terms of this Base Indenture.

 

Anything in this Base Indenture
to the contrary notwithstanding, in no event shall the Indenture Trustee (in any of its capacities) be liable for special, indirect or
consequential loss or damage of any kind whatsoever (including lost profits), even if the Indenture Trustee has been advised of the likelihood
of such a loss or damage and regardless of the form of action.

 

The Securities Intermediary,
the Paying Agent, the Custodian and the Calculation Agent shall be indemnified by the Trust Estate pursuant to Section 4.5
and Section 8.6, and secondarily by the Administrator, in respect of the matters described in Section 4.9 to the
same extent as the Indenture Trustee.

 

    	 	110	 

     

    

 

Neither of the Indenture Trustee
nor the Securities Intermediary will have any recourse to any asset of the Issuer or the Trust Estate other than funds available pursuant
to Section 4.5 and Section 8.6 or to any Person other than the Issuer (or the Administrator pursuant to this Section 11.7).
Except as specified in Section 4.5 and Section 8.6, any such payment to the Indenture Trustee shall be subordinate
to payments to be made to Noteholders.

 

The Indenture Trustee is not
responsible for any action or inaction of the Administrative Agent.

 

Section 11.8.Corporate
Indenture Trustee Required; Eligibility.

 

There will at all times be
an Indenture Trustee hereunder with respect to all Classes of Notes, which will be either a bank or a corporation organized and doing
business under the laws of the United States of America or of any state, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by a federal or state authority of
the United States, and the long-term unsecured debt obligation of which are rated at least BBB from each Note Rating Agency then rating
Outstanding Notes if such institution is rated by the Note Rating Agency, as applicable, or if such Note Rating Agency downgrades the
Indenture Trustee below such minimum rating, the Indenture Trustee may obtain, at its own expense, a confirmation from such Note Rating
Agency that downgraded the Indenture Trustee below such rating category that there is no Ratings Effect by reason of such downgrade to
a lower rating. If such bank or corporation publishes reports of condition at least annually, pursuant to law or to the requirements of
the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such bank
or corporation will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.
The Issuer may not, nor may any Person directly or indirectly Controlling, Controlled by, or under common Control with the Issuer, serve
as Indenture Trustee. If at any time the Indenture Trustee ceases to be eligible in accordance with the provisions of this Section 11.8,
it shall resign upon failure to obtain such confirmation within a reasonable time (not to exceed thirty (30) Business Days) after such
ineligibility in the manner and with the effect hereinafter specified in this Article.

 

Section 11.9.Resignation
and Removal; Appointment of Successor.

 

(a)            No
resignation or removal of the Indenture Trustee and no appointment of a successor Indenture Trustee pursuant to this Article will
become effective until the acceptance of appointment by the successor Indenture Trustee under Section 11.10.

 

(b)            The
Indenture Trustee and the bank serving as Indenture Trustee (in all capacities) may resign with respect to all, but not less than all,
such capacities and all, but not less than all of the Outstanding Notes at any time by giving written notice thereof to the Issuer. If
an instrument of acceptance by a successor Indenture Trustee, Calculation Agent, Paying Agent or Securities Intermediary shall not have
been delivered to the Indenture Trustee within thirty (30) days after the giving of such notice of resignation, the resigning Indenture
Trustee, Calculation Agent, Paying Agent or Securities Intermediary may petition any court of competent jurisdiction for the appointment
of a successor Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary. Written notice of resignation by the Indenture
Trustee under this Base Indenture shall also constitute notice of resignation as Calculation Agent, Securities Intermediary, Paying Agent,
and Note Registrar hereunder, to the extent the Indenture Trustee serves in such a capacity at the time of such resignation.

 

    	 	111	 

     

    

 

(c)            The
Indenture Trustee or Calculation Agent may be removed with respect to all Outstanding Notes at any time by Action of the Majority Noteholders
of all Outstanding Notes, delivered to the Indenture Trustee and to the Issuer. Removal of the Indenture Trustee shall also constitute
removal of the Calculation Agent, Securities Intermediary, Note Registrar and Paying Agent hereunder, to the extent the Indenture Trustee
serves in such a capacity at the time of such resignation. If an instrument of acceptance by a successor Indenture Trustee or Calculation
Agent shall not have been delivered to the Indenture Trustee within thirty (30) days after the giving of such notice of removal, the Indenture
Trustee or Calculation Agent being removed may petition any court of competent jurisdiction for the appointment of a successor Indenture
Trustee or Calculation Agent.

 

(d)            If
at any time:

 

(i)            the
Indenture Trustee ceases to be eligible under Section 11.8 and fails to resign after written request therefore by the Issuer
or by any Noteholder; or

 

(ii)            the
Indenture Trustee becomes incapable of acting with respect to any Series or Class of Notes; or

 

(iii)            the
Indenture Trustee is adjudged bankrupt or insolvent or a receiver of the Indenture Trustee or of its property is appointed or any public
officer takes charge or Control of the Indenture Trustee or of its property or affairs for the purpose of rehabilitation, conservation
or liquidation,

 

then, in any such case, (A) the Issuer may
remove the Indenture Trustee, or (B) subject to Section 8.8, any Noteholder who has been a bona fide Noteholder of a
Note for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Indenture Trustee and the appointment of a successor Indenture Trustee.

 

(e)            If
the Indenture Trustee or Calculation Agent resigns, is removed or becomes incapable of acting with respect to any Notes, or if a vacancy
shall occur in the office of the Indenture Trustee or Calculation Agent for any cause, the Issuer, subject to the Administrative Agent’s
consent, will promptly appoint a successor Indenture Trustee or Calculation Agent. If, within one year after such resignation, removal
or incapacity, or the occurrence of such vacancy, a successor Indenture Trustee or Calculation Agent is appointed by Act of the Majority
Noteholders of all Outstanding Notes, delivered to the Issuer and the retiring Indenture Trustee or Calculation Agent, the successor Indenture
Trustee or Calculation Agent so appointed will, forthwith upon its acceptance of such appointment, become the successor Indenture Trustee
or Calculation Agent and supersede the successor Indenture Trustee or Calculation Agent appointed by the Issuer. If no successor Indenture
Trustee or Calculation Agent shall have been so appointed by the Issuer or the Noteholders and accepted appointment in the manner hereinafter
provided, any Noteholder who has been a bona fide Noteholder of a Note for at least six (6) months may, on behalf of itself and all
others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee or Calculation
Agent.

 

    	 	112	 

     

    

 

(f)            The
Issuer will give written notice of each resignation and each removal of the Indenture Trustee and each appointment of a successor Indenture
Trustee to each Noteholder as provided in Section 1.7 and to each Note Rating Agency that is then rating Outstanding Notes.
To facilitate delivery of such notice, upon request by the Issuer, the Note Registrar shall provide to the Issuer a list of the relevant
registered Noteholders. Each notice will include the name of the successor Indenture Trustee and the address of its principal Corporate
Trust Office.

 

Section 11.10.Acceptance
of Appointment by Successor.

 

Every successor Indenture
Trustee appointed hereunder will execute, acknowledge and deliver to the Issuer and to the predecessor Indenture Trustee an instrument
accepting such appointment, with a copy to each Note Rating Agency then rating any Outstanding Notes, and thereupon the resignation or
removal of the predecessor Indenture Trustee will become effective, and such successor Indenture Trustee, without any further act, deed
or conveyance, will become vested with all the rights, powers, trusts and duties of the predecessor Indenture Trustee, Calculation Agent,
Securities Intermediary, Note Registrar and Paying Agent; but, on request of the Issuer or the successor Indenture Trustee, such predecessor
Indenture Trustee will, upon payment of its reasonable charges, if any, execute and deliver an instrument transferring to such successor
Indenture Trustee all the rights, powers and trusts of the predecessor Indenture Trustee, Calculation Agent, Securities Intermediary,
Note Registrar and Paying Agent, and will duly assign, transfer and deliver to such successor Indenture Trustee all property and money
held by such predecessor Indenture Trustee hereunder, subject nevertheless to its rights to payment pursuant to Section 11.7.
Upon request of any such successor Indenture Trustee, the Issuer will execute any and all instruments for more fully and certainly vesting
in and confirming to such successor Indenture Trustee all such rights, powers and trusts.

 

No successor Indenture Trustee
will accept its appointment unless at the time of such acceptance such successor Indenture Trustee will be qualified and eligible under
this Article XI.

 

Section 11.11.Merger,
Conversion, Consolidation or Succession to Business.

 

Any Person into which the
Indenture Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion
or consolidation to which the Indenture Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate
trust business of the Indenture Trustee, will be the successor of the Indenture Trustee hereunder, provided that such Person shall
be otherwise qualified and eligible under this Article XI, without the execution or filing of any paper or any further act
on the part of any of the parties hereto. The Indenture Trustee will give prompt written notice of such merger, conversion, consolidation
or succession to the Issuer and each Note Rating Agency that is then rating Outstanding Notes. If any Notes shall have been authenticated,
but not delivered, by the Indenture Trustee then in office, any successor by merger, conversion or consolidation to such authenticating
Indenture Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Indenture
Trustee had itself authenticated such Notes.

 

    	 	113	 

     

    

 

Section 11.12.Appointment
of Authenticating Agent.

 

At any time when any of the
Notes remain Outstanding the Indenture Trustee, with the approval of the Issuer, may appoint an Authenticating Agent with respect to one
or more Series or Classes of Notes which will be authorized to act on behalf of the Indenture Trustee to authenticate Notes of such
Series or Classes issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 6.5,
and Notes so authenticated will be entitled to the benefits of this Base Indenture and will be valid and obligatory for all purposes as
if authenticated by the Indenture Trustee hereunder. Wherever reference is made in this Base Indenture to the authentication and delivery
of Notes by the Indenture Trustee or an Indenture Trustee Authorized Signatory or to the Indenture Trustee’s Certificate of Authentication,
such reference will be deemed to include authentication and delivery on behalf of the Indenture Trustee by an Authenticating Agent and
a Certificate of Authentication executed on behalf of the Indenture Trustee by an Authenticating Agent. Each Authenticating Agent will
be acceptable to the Issuer and will at all times be a Person organized and doing business under the laws of the United States of America,
any State thereof or the District of Columbia, authorized under such laws to act as an Authenticating Agent, having a combined capital
and surplus of not less than $50,000,000 and, if other than the Issuer itself, subject to supervision or examination by a federal or state
authority of the United States. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.
If at any time an Authenticating Agent will cease to be eligible in accordance with the provisions of this Section, such Authenticating
Agent will resign immediately in the manner and with the effect specified in this Section.

 

Any Person into which an Authenticating
Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation
to which such Authenticating Agent will be a party, or any Person succeeding to the corporate agency or corporate trust business of an
Authenticating Agent, will continue to be an Authenticating Agent, provided that such Person will be otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the part of the Indenture Trustee or the Authenticating Agent.

 

An Authenticating Agent may
resign at any time by giving written notice thereof to the Indenture Trustee and to the Issuer. The Indenture Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuer. Upon
receiving such a notice of resignation or upon such a termination, or if at any time such Authenticating Agent ceases to be eligible in
accordance with the provisions of this Section, the Indenture Trustee, with the approval of the Issuer, may appoint a successor Authenticating
Agent which will be acceptable to the Issuer and will make such notice available to each Noteholder as provided in Section 1.7.
Any successor Authenticating Agent upon acceptance of its appointment hereunder will become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent will
be appointed unless eligible under the provisions of this Section.

 

    	 	114	 

     

    

 

 

The Indenture Trustee agrees
to pay to each Authenticating Agent (other than an Authenticating Agent appointed at the request of the Issuer, the Noteholders or the
Administrator from time to time or appointed due to a change in law or other circumstance beyond the Indenture Trustee’s control)
reasonable compensation for its services under this Section, out of the Indenture Trustee’s own funds without reimbursement pursuant
to this Base Indenture. The Indenture Trustee shall be the initial Authenticating Agent.

 

Section 11.13.Direction
to Indenture Trustee under the PC Repo Guaranty.

 

In the event the Administrative
Agent, on behalf of the Noteholders, determines that the Indenture Trustee, as a beneficiary under the PC Repo Guaranty, should take
certain action to preserve any interests of, or release any lien or security interest of, the Noteholders under the terms of the PC Repo
Guaranty, with respect to the Collateral, the Noteholders acknowledge and agree that the Indenture Trustee shall only take such action
as may be directed by the Administrative Agent in writing.

 

Section 11.14.Representations
and Covenants of the Indenture Trustee.

 

The Indenture Trustee, in
its individual capacity and not as Indenture Trustee, represents, warrants and covenants that:

 

(a)            Citibank
is a national banking association duly organized and validly existing under the laws of the United States;

(d)            Citibank
has a minimum aggregate capital, surplus and undivided profits of at least $500,000.

 

Section 11.15.Indenture
Trustee’s Application for Instructions from the Issuer.

 

Any application by the Indenture
Trustee for written instructions from the Issuer may, at the option of the Indenture Trustee, set forth in writing any action proposed
to be taken or omitted by the Indenture Trustee under and in accordance with this Base Indenture and the date on and/or after which such
action shall be taken or such omission shall be effective, provided that such application shall make specific reference to this
Section 11.15. The Indenture Trustee shall not be liable for any action taken by, or omission of, the Indenture Trustee in
accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less
than five (5) Business Days after the date the Issuer actually receives such application, unless the Issuer shall have consented
in writing to any earlier date) unless prior to taking any such action (or the Closing Date in the case of an omission), the Indenture
Trustee shall have received written instructions in response to such application specifying the action be taken or omitted.

deliver to the Indenture Trustee an Officer’s Certificate to the effect that the Issuer reasonably believes that such amendment
could not have a material Adverse Effect on any Outstanding Notes and is not reasonably expected to have a material Adverse Effect at
any time in the future, and (ii) if any Outstanding Notes are then rated by a Note Rating Agency, (1) each such Note Rating
Agency confirms in writing to the Indenture Trustee that such amendment will not cause a Ratings Effect on any Outstanding Notes or (2) if
the Administrator and the Administrative Agents determine in their reasonable judgment that an applicable Note Rating Agency no longer
provides such written confirmation described in the foregoing clause (1), (a) the Administrator shall provide notice of such

in its sole and absolute discretion, upon the written direction of PLS, as Repo Seller, to sell a portion of Excess Spread to the Guarantor

Security Interest of the Indenture Trustee under this Indenture, and (ii) the assignee of such Excess Spread shall execute and deliver
a written agreement, satisfactory to Fannie Mae, the Indenture Trustee (at the written direction of the VFN Noteholders) and the VFN
Noteholders in their sole and absolute discretion, acknowledging the subordinate nature of such assignee’s interests in the portion
of such Excess Spread to the Indenture Trustee’s Security Interests in the Collateral under this Indenture. In connection with
any such sale of Excess Spread, the parties to this Indenture agree to use reasonable efforts to cause the parties to the Transaction
Documents to execute and deliver such Indenture Supplements and amendments, restatements, modifications or other supplements to the Transaction
Documents as may be necessary or advisable to effect the sale of such Excess Spread pursuant to this Section 12.1(e), provided,

any manner or eliminating any of the provisions of, this Base Indenture of modifying in any manner the rights of the Noteholders of the

(b)            reduce
the Note Balance of, or the Note Interest Rate, the Step-Up Fee Rate or the Default Supplemental Fee Rate on any Note held by such Noteholder,

(c)            impair
the right to institute suit for the enforcement of any payment on any Note held by such Noteholder;

 

    	 	118	 

     

    

 

(d)            reduce
the percentage of Noteholders of the Outstanding Notes (or of the Outstanding Notes of any Series or Class), whose consent is required

(e)            modify
any of the provisions of this Section or Section 8.14, except to increase any percentage of Noteholders required to

or waived without the consent of the Noteholder of each Outstanding Note adversely affected thereby;

 

(f)            permit
the creation of any lien or other encumbrance on the Collateral that is prior to the lien in favor of the Indenture Trustee for the benefit
of the Noteholders of the Notes;

 

(g)            change
the method of computing the amount of principal of, or interest on, any Note held by such Noteholder on any date;

of this Section 12.2 or as otherwise specified in Section 12.1(e) or the applicable Indenture Supplement.
The consent of a Person that is an Administrative Agent for one or more Series but is not an Administrative Agent for any other
Series is not required for any amendment, supplement or modification to any such other Series.

 

An amendment of this Base
Indenture which changes or eliminates any covenant or other provision of this Base Indenture which has expressly been included solely
for the benefit of one or more particular Series or Class of Notes, or which modifies the rights of the Noteholders of Notes
of such Series or Class with respect to such covenant or other provision, will be deemed not to affect the rights under this
Base Indenture of the Noteholders of Notes of any other Series or Class.

 

It will not be necessary
for any Act of Noteholders under this Section to approve the particular form of any proposed amendment, but it will be sufficient
if such Act will approve the substance thereof.

 

In addition to the foregoing,
each Holder of a Term Note and any transferee thereto, by accepting such Term Note shall be deemed to have consented to, and the Issuer,
the Administrator, the Servicer, the Administrative Agent and the Indenture Trustee upon prior notice to each Note Rating Agency may
enter into, any amendment, restatement, modification or supplement to this Base Indenture, an Indenture Supplement or any other Transaction
Document for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Base Indenture
or modifying in any manner the rights of the such Holders of Term Notes under this Base Indenture, any related Indenture Supplement or
any other Transaction Document as may be necessary or advisable, (i) upon delivery of a certification relating to the purpose of
such amendment by the Servicer to the Indenture Trustee, to which the Indenture Trustee may conclusively rely, (ii) with the consent
of the Issuer (evidenced by its execution of such amendment), the Indenture Trustee and the Administrative Agent, and (iii) with
the consent of the VFN Noteholders, to cure any inconsistency between this Base Indenture, any Indenture Supplement or any other Transaction

In executing or accepting
the additional trusts created by any amendment or Indenture Supplement of this Base Indenture permitted by this Article XII
or the modifications thereby of the trusts created by this Base Indenture, the Indenture Trustee will be entitled to receive, and (subject
to Section 11.1) will be fully protected in relying upon, an Opinion of Counsel stating that the execution of such amendment
or Indenture Supplement is authorized and permitted by this Base Indenture and that all conditions precedent thereto have been satisfied.

of Amendments.

 

Upon the execution of any
amendment of this Base Indenture or any Indenture Supplement, or any supplemental indentures under this Article XII, this

Notes affected thereby, or all Notes, as the case may be, and such amendment will form a part of this Base Indenture and the related

matter provided for in such amendment or supplemental indenture. If the Issuer so determines, new Notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuer, to any such amendment or supplemental indenture may be prepared and executed by

Article XIII

 

Early Redemption of Notes

 

Section 13.1.Optional
Redemption.

 

(a)            Unless
otherwise provided in the applicable Indenture Supplement for a Series or Class of Notes, the Issuer has the right, but not
the obligation, to: (i) redeem a Series or Class of Term Notes in whole or in part (so long as, in the case of any partial
redemption, such redemption is funded using the proceeds of the issuance and sale of one or more new Classes of Notes as further specified
in the related Indenture Supplement or from any other amounts received by the Issuer pursuant to the PC Repurchase Agreement (or otherwise)
other than Collections on MSRs) on a date specified in the applicable Indenture Supplement or on any Payment Date (a “Redemption
Payment Date”) on or after the Payment Date on which the aggregate Note Balance (after giving effect to all payments, if
any, on that day) of such Series or Class is reduced to less than the Redemption Percentage of the Initial Note Balance and
(ii) redeem a Series or Class of Variable Funding Notes in whole or in part on a date specified in the applicable Indenture
Supplement.

 

If the Issuer, at the direction
of the Administrator, elects to redeem a Series or Class of Notes pursuant to this Section 13.1, it will cause
the Issuer to notify the Indenture Trustee and the Noteholders of such redemption at least ten (10) days (or other times specified
in the related Indenture Supplement) prior to the Redemption Payment Date. Unless otherwise specified in the Indenture Supplement applicable
to the Notes to be so redeemed, the redemption price of a Series or Class so redeemed will equal the Redemption Amount, the
payment of which will be subject to the allocations, deposits and payments sections of the related Indenture Supplement, if any.

 

If the Issuer is unable to
pay the Redemption Amount in full on the Redemption Payment Date, such redemption shall be cancelled, notice of such cancelled redemption
shall be sent to all Secured Parties and payments on such Series or Class of Notes will thereafter continue to be made in accordance
with this Base Indenture and the related Indenture Supplement, and the Noteholders of such Series or Class of Notes and the
related Administrative Agent shall continue to hold all rights, powers and options as set forth under this Base Indenture, until the
Outstanding Note Balance of such Series or Class, plus all accrued and unpaid interest and other amounts due in respect of the Notes,
is paid in full or the Stated Maturity Date occurs, whichever is earlier, subject to Article VII, Article VIII
and the allocations, deposits and payments sections of this Base Indenture and the related Indenture Supplement.

 

(b)            Unless
otherwise specified in the related Indenture Supplement, if the VFN Principal Balance of any Class of VFNs has been reduced to zero,
then, upon five (5) Business Days’ prior written notice to the Noteholder thereof, the Issuer may declare such Class no
longer Outstanding, in which case the Noteholder thereof shall submit such Class of Notes to the Indenture Trustee for cancellation.

 

    	 	121	 

     

    

 

(c)            The
Notes of any Series or Class of Notes shall be subject to optional redemption under this Article XIII, in whole
but not in part, by the Issuer, through (i) the use of the proceeds of issuance and sale of a new Series of Notes issued hereunder,
or (ii) the use of the proceeds received of any amounts funded under any Variable Funding Notes on any Business Day after the date
on which the related Revolving Period ends, and on any Business Day within five (5) days prior to the end of such Revolving Period
or at other times specified in the related Indenture Supplement upon five (5) days’ prior notice to the Indenture Trustee
and the Noteholders. Following issuance of the Redemption Notice by the Issuer pursuant to Section 13.2 below, the Issuer
shall be required to purchase the entire aggregate Note Balance of such Series or Class of Term Notes for the applicable Redemption
Amount on the date set for such redemption.

 

(d)            The
Issuer may redeem any Series or Class of Notes through (i) the use of proceeds from the issuance and sale of a new Series or
Class of Notes issued hereunder, or (ii) the use of proceeds received following a VFN Note Balance Adjustment Request, on any
other Business Day specified in the related Indenture Supplement.

 

(e)            If
necessary to avoid a Borrowing Base Deficiency, the Notes of any Series or Class of Variable Funding Notes shall be subject
to repayment by the Issuer, in whole or in part, up to the amount necessary to avoid a Borrowing Base Deficiency, using any other cash
or funds of the Issuer other than Collections on the Participation Certificates, upon two (2) Business Day’s prior notice
from the Issuer to the Indenture Trustee and the related VFN Noteholders. Any such repayment pursuant to this Section 13.1(d) shall
reduce the principal balance of such Variable Funding Notes but shall not result in a reduction of any funding commitments related thereto
or the Maximum VFN Principal Balance thereof (unless otherwise agreed between the Noteholders of such Variable Funding Notes and the
Issuer) and (ii) may be made on a non-pro rata basis with other Series of Variable Funding Notes.

 

(f)            Notwithstanding
any other provision of this Base Indenture, the early redemption rights of the Issuer set forth in this Section 13.1 are
in addition to, the Issuer’s rights set forth in Section 2.01(b)(ii) to remove as Collateral the Participation
Certificates and Mortgage Loans.

 

Section 13.2.Notice.

 

(a)            Promptly
after the election to exercise any optional redemption pursuant to Section 13.1, the Issuer will notify the Indenture Trustee
and each related Note Rating Agency in writing of the identity and Note Balance of the affected Series or Class of Notes to
be redeemed.

 

(b)            Notice
of redemption (each a “Redemption Notice”) will promptly be given as provided in Section 1.7. All
notices of redemption will state (i) the Series or Class of Notes to be redeemed pursuant to this Article XIII,
(ii) the date on which the redemption of the Series or Class of Notes to be redeemed pursuant to this Article will
begin, which will be the Redemption Payment Date, and (iii) the redemption price for such Series or Class of Notes.

Article XIV

 

Miscellaneous

 

Section 14.1.No
Petition.

 

Each of the Indenture Trustee,
the Administrative Agent, the Servicer and the Administrator, by entering into this Base Indenture, each Noteholder, by accepting a Note
and each Note Owner by accepting a Note or a beneficial interest in a Note agrees that it will not at any time prior to the date which
is one year and one day, or, if longer, the applicable preference period then in effect, after the payment in full of all the Notes,
institute against the Issuer, or join in any institution against the Issuer of, any receivership, insolvency, bankruptcy or other similar
proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations
relating to the Notes and this Base Indenture; provided, however, that nothing contained herein shall prohibit or otherwise
prevent the Indenture Trustee from filing proofs of claim in any such proceeding.

 

Section 14.2.No
Recourse.

 

No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i) the Indenture Trustee or Owner Trustee in their
individual capacities, (ii) any owner of a beneficial ownership interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director, employee or “control person” within the meaning of the 1933 Act and the 1934 Act of the Indenture
Trustee or Owner Trustee in its individual capacity, any holder of a beneficial ownership interest in the Issuer or the Indenture Trustee
or Owner Trustee or of any successor or assign of the Indenture Trustee or Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided
by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing
to such entity.

 

Section 14.3.Tax
Treatment.

 

Notwithstanding anything
to the contrary set forth herein, the Issuer has entered into this Base Indenture with the intention that for United States federal,
state and local income and franchise tax purposes the Notes will qualify as indebtedness secured by the Participation Certificates and
the MSRs, unless retained by the Issuer or a single beneficial owner of the equity of the Issuer for U.S. federal income tax purposes
or a single affiliate of the Issuer whose ownership would cause the Notes to be treated as equity under Treasury Regulations promulgated
under section 385 of the Code (each, a “Retained Note”). The Issuer, by entering into this Base Indenture,
each Noteholder, by its acceptance of a Note and each purchaser of a beneficial interest therein, by accepting such beneficial interest,
agree to treat such Notes (other than any Retained Note) as debt for United States federal, state and local income and franchise tax
purposes, unless otherwise required by applicable law in a proceeding of final determination. The Indenture Trustee shall treat the Trust
Estate as a security device only. The provisions of this Base Indenture shall be construed in furtherance of the foregoing intended tax
treatment.

 

    	 	123	 

     

    

 

Section 14.4.Alternate
Payment Provisions.

 

Notwithstanding any provision
of this Base Indenture or any of the Notes to the contrary, the Issuer, with the written consent of the Indenture Trustee and the Paying
Agent, may enter into any agreement with any Noteholder of a Note providing for a method of payment or notice that is different from
the methods provided for in this Base Indenture for such payments or notices. The Issuer will furnish to the Indenture Trustee and the
Paying Agent a copy of each such agreement and the Indenture Trustee and the Paying Agent will cause payments or notices, as applicable,
to be made in accordance with such agreements.

 

Section 14.5.Termination
of Obligations.

 

The respective obligations
and responsibilities of the Indenture Trustee created hereby (other than the obligation of the Indenture Trustee to make payments to
Noteholders as hereinafter set forth) shall terminate upon satisfaction and discharge of this Base Indenture as set forth in Article VII,
except with respect to the payment obligations described in Section 14.6(b). Upon this event, the Indenture Trustee shall
release, assign and convey to the Issuer or any of its designees, without recourse, representation or warranty, all of its right, title
and interest in the Collateral, whether then existing or thereafter created, all monies due or to become due and all amounts received
or receivable with respect thereto (including all monies then held in any Trust Account) and all proceeds thereof, except for amounts
held by the Indenture Trustee pursuant to Section 14.6(b). The Indenture Trustee shall execute and deliver such instruments
of transfer and assignment as shall be provided to it, in each case without recourse, as shall be reasonably requested by the Issuer
to vest in the Issuer or any of its designees all right, title and interest which the Indenture Trustee had in the Collateral.

 

Section 14.6.Final
Payment.

 

(a)            The
Issuer shall give the Indenture Trustee at least ten (10) days’ prior written notice of the Payment Date on which the Noteholders
of any Series or Class may surrender their Notes for payment of the final payment on and cancellation of such Notes. Not later
than the fifth (5th) day prior to the Payment Date on which the final payment in respect of such Series or Class is
payable to Noteholders, the Indenture Trustee or the Paying Agent shall provide notice to Noteholders of such Series or Class specifying
(i) the date upon which final payment of such Series or Class will be made upon presentation and surrender of Notes of
such Series or Class at the office or offices therein designated, (ii) the amount of any such final payment and (iii) that
the Record Date otherwise applicable to such payment date is not applicable, payments being made only upon presentation and surrender
of such Notes at the office or offices therein specified. The Indenture Trustee shall give such notice to the Note Registrar and the
Paying Agent at the time such notice is given to Noteholders.

 

(b)            Notwithstanding
a final payment to the Noteholders of any Series or Class (or the termination of the Issuer), except as otherwise provided
in this paragraph, all funds then on deposit in any Account allocated to such Noteholders shall continue to be held in trust for the
benefit of such Noteholders, and the Paying Agent or the Indenture Trustee shall pay such funds to such Noteholders upon surrender of
their Notes, if such Notes are Definitive Notes. In the event that all such Noteholders shall not surrender their Notes for cancellation
within six (6) months after the date specified in the notice from the Indenture Trustee described in clause (a) above,
the Indenture Trustee shall give a second (2nd) notice to the remaining such Noteholders to surrender their Notes for cancellation
and receive the final payment with respect thereto. If within one year after the second (2nd) notice all such Notes shall
not have been surrendered for cancellation, the Indenture Trustee may take appropriate steps, or may appoint an agent to take appropriate
steps, to contact the remaining such Noteholders concerning surrender of their Notes, and the cost thereof (including costs related to
giving the second (2nd) notice) shall be paid out of the funds in the Collection and Funding Account. The Indenture Trustee
and the Paying Agent shall pay to the Issuer any monies held by them for the payment of principal or interest that remains unclaimed
for two (2) years. After payment to the Issuer, Noteholders entitled to the money must look to the Issuer for payment as general
creditors unless an applicable abandoned property law designates another Person.

Section 14.7.Base
Servicing Fee.

 

The parties hereto acknowledge
that PLS has the right to withdraw the Base Servicing Fee with respect to any Portfolio Mortgage Loan out of collections it receives

It is expressly understood
and agreed by the parties hereto that (a) this Base Indenture is executed and delivered by Wilmington Savings Fund Society, FSB
(“WSFS”), 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 WSFS 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 WSFS, 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) WSFS has made
no investigation as to the accuracy or completeness of any representations or warranties made by the Issuer in this Base Indenture and
(e) under no circumstances shall WSFS 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 Base Indenture
or any other related documents.

 

Section 14.9.Communications
with Rating Agencies.

Agent or the Indenture Trustee shall receive any written or oral communication from any Note Rating Agency (or any of the respective
officers, directors or employees of any Note Rating Agency) with respect to the transactions contemplated hereby or under the Transaction
Documents or in any way relating to the Notes, the Servicer, the Administrative Agent and the Indenture Trustee agree to refrain from
communicating with such Note Rating Agency and to promptly notify the Administrator of such communication; provided, however,
that if the Servicer, the Administrative Agent or the Indenture Trustee receives an oral communication from a Note Rating Agency, the
Servicer, the Administrative Agent or the Indenture Trustee, as the case may be, is authorized to refer such Note Rating Agency to the
Administrator, who will respond to such oral communication. At the written request of the Administrator, the Servicer, the Administrative
Agent and the Indenture Trustee agree to cooperate with the Administrator to provide certain information to the Administrator that may
be reasonably required by a Note Rating Agency to rate or to perform ratings surveillance on the Notes, and acknowledge and agree that
the Administrator shall be permitted, in turn, to provide such information to the Note Rating Agencies via the internet address identified
therefor by the Administrator; provided, that the Servicer, the Administrative Agent and the Indenture Trustee shall only be required
to provide such information that is reasonably available to such party at the time of request. Notwithstanding any other provision of
this Base Indenture or the other Transaction Documents, under no circumstances shall the Servicer, the Administrative Agent or the Indenture
Trustee be required to participate in telephone conversations or other oral communications with a Note Rating Agency, nor shall the Servicer,
the Administrative Agent or the Indenture Trustee be prohibited from communicating with any nationally recognized statistical rating
organization about matters other than the Notes or the transactions contemplated hereby or by the Transaction Documents. Furthermore,
the Indenture Trustee may make statements to Noteholders available on its website (as contemplated by Section 3.5(a) hereof),
and such action is not prohibited by this Section 14.9.

of the Issuer’s Duties by the Owner Trustee and the Administrator.

 

(a)            The

Administrator pursuant to the Administration Agreement and hereby acknowledge and accept the terms of such agreement as of the date hereof

verifying ownership or another similar document evidencing ownership of a Note. The Indenture Trustee will not be required to take action
in response to requests, demands or directions of a Noteholder or a Note Owner, unless the Noteholder or Note Owner has offered reasonable

relating to the Notes and this Indenture.

 

The Issuer has entered into
the Indenture and this Note is issued with the intention that, for United States federal, state and local income and franchise tax purposes,
the Notes will qualify as indebtedness secured by the Collateral. Each Noteholder, by its acceptance of a Note, and each purchaser of
a beneficial interest therein, by accepting such beneficial interest, agrees to treat such Notes as debt for United States federal, state
and local income and franchise tax purposes, unless otherwise required by Applicable Law in a proceeding of final determination.

 

Prior to the due presentment
for registration of transfer of this Note, the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent and any agent of the
Issuer, the Note Registrar, the Paying Agent or the Indenture Trustee may treat the Person in whose name this Note (as of the day of determination

Note be overdue, and none of the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent or any such agent shall be affected
by notice to the contrary.

certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer or other
parties thereto and the rights of the Holders of the Notes under the Indenture at any time pursuant to the terms and provisions of Article XII
of the Base Indenture and Section [ ] of the [Series Name] Indenture Supplement. The Indenture also contains provisions permitting
the Holders of Notes representing specified percentages of the Outstanding Notes or a particular Class of Notes, on behalf of all
of the Noteholders, or the Administrative Agent, as applicable, to waive compliance by the Issuer with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note (or any one
or more predecessor Notes) shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is
made upon this Note. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of any Noteholder.

Notwithstanding any other provisions
herein or in the Indenture, a Holder of this Note will have the right, which is absolute and unconditional, to receive payment of the
principal of and interest on this Note on the Stated Maturity Date and to institute suit for the enforcement of any such payment, and
such right will not be impaired without the consent of the Holder; provided, however, that notwithstanding any other provision
of the Indenture to the contrary, the obligation to pay principal of or interest on this Note or any other amount payable to the Holder
will be without recourse to the Administrator, the Servicer, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities
Intermediary or any Affiliate (other than the Issuer), officer, employee or director of any of them, and the obligation of the Issuer
to pay principal of or interest on this Note or any other amount payable to the Holder will be limited to amounts available from the Trust
Estate and subject to the priority of payment set forth in the Indenture.

 

Notwithstanding any other terms
of the Indenture or this Note, the obligations of the Issuer hereunder 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 the Indenture, the Holder hereof shall not 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 Holder of this Note shall have
recourse for the payment of any amount owing in respect of this Note or the Indenture 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 this Note or the Indenture. The foregoing provisions of this Note shall not (i) 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, (ii) save
as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by this Note or
secured by the Indenture, or (iii) 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 this Note or the Indenture, 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.

relating to the Notes and this Indenture

 

The Issuer has entered into
the Indenture and this Note is issued with the intention that, for United States federal, state and local income and franchise tax purposes,
the Notes will qualify as indebtedness secured by the Collateral. Each Noteholder, by its acceptance of a Note, and each purchaser of
a beneficial interest therein, by accepting such beneficial interest, agrees to treat such Notes as debt for United States federal, state
and local income and franchise tax purposes, unless otherwise required by Applicable Law in a proceeding of final determination.

be affected by notice to the contrary.

certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer or other
parties thereto and the rights of the Holders of the Notes under the Indenture at any time pursuant to the terms and provisions of Article XII

of the Noteholders, or the Administrative Agent, as applicable, to waive compliance by the Issuer with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note (or any one
or more predecessor Notes) shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver
is made upon this Note. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in

principal of and interest on this Note on the Stated Maturity Date and to institute suit for the enforcement of any such payment, and
such right will not be impaired without the consent of the Holder; provided, however, that notwithstanding any other provision

to pay principal of or interest on this Note or any other amount payable to the Holder will be limited to amounts available from the
Trust Estate and subject to the priority of payment set forth in the Indenture.

 

Notwithstanding any other terms
of the Indenture or this Note, the obligations of the Issuer hereunder 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 the Indenture, the Holder hereof shall not 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 Holder of this Note shall have
recourse for the payment of any amount owing in respect of this Note or the Indenture 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 this Note or the Indenture. The foregoing provisions of this Note shall not (i) 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, (ii) save
as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by this Note

Noteholder will be subject and subordinate in all respects to all rights, powers, and prerogatives of Fannie Mae under the Fannie Mae
Lender Contract, and no Noteholder enjoys privity of contract with Fannie Mae or is entitled to any benefit under the Acknowledgment

As provided in the Indenture
and subject to certain limitations set forth therein, the transfer of this Note may be registered on the Note Register upon surrender

or accompanied by a written instrument of transfer in the form attached hereto duly executed by, the Holder hereof or such Holder’s
attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements

No service charge will be charged for any registration of transfer or exchange of this Note, but the Issuer may require the Noteholder

transfer or exchange.

 

Each Noteholder, by acceptance
of a Note or a beneficial ownership interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with
respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or other writing
delivered in connection therewith, against (i) the Indenture Trustee or Owner Trustee in their individual capacities, (ii) any
owner of a beneficial ownership interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director, employee
or “control person” within the meaning of the 1933 Act and the Securities Exchange Act of 1934, as amended, of the Indenture
Trustee or Owner Trustee in its individual capacity, any holder of a beneficial ownership interest in the Issuer or the Indenture Trustee
or Owner Trustee or of any successor or assign of the Indenture Trustee or Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided
by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing
to such entity.

 

    	 	Exhibit A-3-9	 

     

    

 

Each Noteholder, by accepting
a Note and each Note Owner by accepting a Note or a beneficial interest in a Note agrees that it will not at any time prior to the date
which is one year and one day, or, if longer, the applicable preference period then in effect, after the payment in full of all the Notes,
institute against the Issuer, or join in any institution against the Issuer of, any receivership, insolvency, bankruptcy or other similar
proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations
relating to the Notes and this Indenture.

 

The Issuer has entered into
the Indenture and this Note is issued with the intention that, for United States federal, state and local income and franchise tax purposes,
the Notes will qualify as indebtedness secured by the Collateral. Each Noteholder, by its acceptance of a Note, and each purchaser of
a beneficial interest therein, by accepting such beneficial interest, agrees to treat such Notes as debt for United States federal, state
and local income and franchise tax purposes, unless otherwise required by Applicable Law in a proceeding of final determination.

 

Prior to the due presentment
for registration of transfer of this Note, the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent and any agent of the
Issuer, the Note Registrar, the Paying Agent or the Indenture Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all purposes, whether
or not this Note be overdue, and none of the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent or any such agent shall
be affected by notice to the contrary.

 

The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer or other
parties thereto and the rights of the Holders of the Notes under the Indenture at any time pursuant to the terms and provisions of Article XII
of the Base Indenture and Section [ ] of the [Series Name] Indenture Supplement. The Indenture also contains provisions permitting
the Holders of Notes representing specified percentages of the Outstanding Notes or a particular Class of Notes, on behalf of all
of the Noteholders, or the Administrative Agent, as applicable, to waive compliance by the Issuer with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note (or any one
or more predecessor Notes) shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver
is made upon this Note. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of any Noteholder.

The term “Issuer”
as used in this Note includes any successor to the Issuer under the Indenture.

 

Notwithstanding any other provisions
herein or in the Indenture, a Holder of this Note will have the right, which is absolute and unconditional, to receive payment of the
principal of and interest on this Note on the Stated Maturity Date and to institute suit for the enforcement of any such payment, and
such right will not be impaired without the consent of the Holder; provided, however, that notwithstanding any other provision
of the Indenture to the contrary, the obligation to pay principal of or interest on this Note or any other amount payable to the Holder
will be without recourse to the Administrator, the Servicer, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities
Intermediary or any Affiliate (other than the Issuer), officer, employee or director of any of them, and the obligation of the Issuer
to pay principal of or interest on this Note or any other amount payable to the Holder will be limited to amounts available from the Trust
Estate and subject to the priority of payment set forth in the Indenture.

 

Notwithstanding any other terms
of the Indenture or this Note, the obligations of the Issuer hereunder 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 the Indenture, the Holder hereof shall not 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 Holder of this Note shall have
recourse for the payment of any amount owing in respect of this Note or the Indenture 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 this Note or the Indenture. The foregoing provisions of this Note shall not (i) 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, (ii) save
as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by this Note or
secured by the Indenture, or (iii) 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 this Note or the Indenture, 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.

    Exhibit A-4-8

     

    

 

Each Noteholder, by acceptance
of a Note or a beneficial ownership interest in a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with
respect to the obligations of the Issuer or the Indenture Trustee on the Notes or under the Indenture or any certificate or other writing
delivered in connection therewith, against (i) the Indenture Trustee or Owner Trustee in their individual capacities, (ii) any
owner of a beneficial ownership interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director, employee
or “control person” within the meaning of the 1933 Act and the Securities Exchange Act of 1934, as amended, of the Indenture
Trustee or Owner Trustee in its individual capacity, any holder of a beneficial ownership interest in the Issuer or the Indenture Trustee
or Owner Trustee or of any successor or assign of the Indenture Trustee or Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided
by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing
to such entity.

 

Each Noteholder, by accepting
a Note and each Note Owner by accepting a Note or a beneficial interest in a Note agrees that it will not at any time prior to the date
which is one year and one day, or, if longer, the applicable preference period then in effect, after the payment in full of all the Notes,
institute against the Issuer, or join in any institution against the Issuer of, any receivership, insolvency, bankruptcy or other similar
proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations
relating to the Notes and this Indenture.

 

The Issuer has entered into
the Indenture and this Note is issued with the intention that, for United States federal, state and local income and franchise tax purposes,
the Notes will qualify as indebtedness secured by the Collateral. Each Noteholder, by its acceptance of a Note, and each purchaser of
a beneficial interest therein, by accepting such beneficial interest, agrees to treat such Notes as debt for United States federal, state
and local income and franchise tax purposes, unless otherwise required by Applicable Law in a proceeding of final determination.

 

Prior to the due presentment
for registration of transfer of this Note, the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent and any agent of the
Issuer, the Note Registrar, the Paying Agent or the Indenture Trustee may treat the Person in whose name this Note (as of the day of determination
or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all purposes, whether or not this
Note be overdue, and none of the Issuer, the Indenture Trustee, the Note Registrar, the Paying Agent or any such agent shall be affected
by notice to the contrary.

 

The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer or other
parties thereto and the rights of the Holders of the Notes under the Indenture at any time pursuant to the terms and provisions of Article XII
of the Base Indenture and Section [ ] of the [Series Name] Indenture Supplement. The Indenture also contains provisions permitting
the Holders of Notes representing specified percentages of the Outstanding Notes or a particular Class of Notes, on behalf of all
of the Noteholders, or the Administrative Agent, as applicable, to waive compliance by the Issuer with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note (or any one
or more predecessor Notes) shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is
made upon this Note. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of any Noteholder.

 

    Exhibit A-4-9

     

    

 

The term “Issuer”
as used in this Note includes any successor to the Issuer under the Indenture.

 

This Note is issuable only in
definitive form in denominations as provided in the [Series Name] Indenture Supplement, subject to certain limitations therein set
forth.

 

Notwithstanding any other provisions
herein or in the Indenture, a Holder of this Note will have the right, which is absolute and unconditional, to receive payment of the
principal of and interest on this Note on the Stated Maturity Date and to institute suit for the enforcement of any such payment, and
such right will not be impaired without the consent of the Holder; provided, however, that notwithstanding any other provision
of the Indenture to the contrary, the obligation to pay principal of or interest on this Note or any other amount payable to the Holder
will be without recourse to the Administrator, the Servicer, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities
Intermediary or any Affiliate (other than the Issuer), officer, employee or director of any of them, and the obligation of the Issuer
to pay principal of or interest on this Note or any other amount payable to the Holder will be limited to amounts available from the Trust
Estate and subject to the priority of payment set forth in the Indenture.

 

Notwithstanding any other terms
of the Indenture or this Note, the obligations of the Issuer hereunder 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 the Indenture, the Holder hereof shall not 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 Holder of this Note shall have
recourse for the payment of any amount owing in respect of this Note or the Indenture 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 this Note or the Indenture. The foregoing provisions of this Note shall not (i) 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, (ii) save
as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by this Note or
secured by the Indenture, or (iii) 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 this Note or the Indenture, 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.

Reference is hereby made to
the Base Indenture, dated as of April 28, 2021 (as may be amended, restated, supplemented or otherwise modified from time to time,
the “Indenture”), among PFSI ISSUER TRUST – FMSR, as Issuer, PennyMac Loan Services, LLC, as Administrator and
as Servicer, and Citibank, N.A., as Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary, Credit Suisse First
Boston Mortgage Capital LLC, as Administrative Agent, and the “Administrative Agents” from time to time party thereto. Capitalized
terms used but not defined herein shall have the meanings given to them in the Indenture.

 

    Exhibit B-1-5

     

    

 

 

The undersigned (the “Transferee”)
intends to purchase $________ Note Balance of Class __Notes (the “Notes”) from the Transferor named in the Transfer
Certificate to which this Transferee Certification is attached. In connection with the registration of the transfer of such Notes, the
Transferee hereby executes and delivers to each of you this “Transferee Certification” in which the Transferee certifies to
each of you the information set forth herein.

 

1.            The
Transferee is a “qualified institutional buyer” as that term is defined in Rule 144A (“Rule 144A”)
promulgated under the Securities Act of 1933, as amended (the “1933 Act”) and has completed the form of certification
to that effect attached hereto as Annex A1 (if the Transferee is not a registered investment company) or Annex A2 (if the Transferee is
a registered investment company). The Transferee is aware that the sale to it is being made in reliance on Rule 144A.

 

2.            The
Transferee understands that the Notes have not been registered under the 1933 Act or registered or qualified under any state securities
laws and that no transfer may be made unless the Notes are registered under the 1933 Act and under applicable state law or unless the
transfer complies with Section 6.5 of the Indenture and any provision in any applicable Indenture Supplement. The Transferee further
understands that neither the Transferor, the Administrator, the Servicer, the Indenture Trustee nor the Note Registrar is under any obligation
to register the Notes or make an exemption from such registration available.

 

3.            The
Transferee is acquiring the Notes for its own account or for the account of a “qualified institutional buyer” (as defined
in Rule 144A, a “QIB”), and understands that such Notes may be resold, pledged or transferred only (a) to
a person reasonably believed to be such a QIB that purchases for its own account or for the account of a QIB to whom notice is given that
the resale, pledge or transfer is being made in reliance on Rule 144A or (b) to a transferee that is a person that is not a
U.S. person acquiring such interest in an “offshore transaction” (as defined in Regulation S) in compliance with the provisions
of Regulation S, if the transfer is otherwise made in accordance with any applicable securities laws of any state of the United States
or any other relevant jurisdiction. In addition, such transfer may be subject to additional restrictions and is subject to compliance
with certain procedures, as set forth in Section 6.5 of the Indenture referred to below and any provision in any applicable Indenture
Supplement. By its execution of this agreement, the Transferee agrees that it will not resell, pledge or transfer any of the Notes to
anyone otherwise than in strict compliance with Rule 144A, or pursuant to another exemption from registration under the 1933 Act
and all applicable state securities laws, and in strict compliance with the transfer restrictions set forth in Section 6.5 of the
Indenture. The Transferee will not attempt to transfer any or all of the Notes pursuant to Rule 144A unless the Transferee offers
and sells such Certificates only to QIBs or to offerees or purchasers that the Transferee and any person acting on behalf of the Transferee
reasonably believe (as described in paragraph (d)(l) of Rule 144A) is a QIB.

 

    Exhibit B-1-6

     

    

 

4.            The
Transferee has been furnished with all information that it requested regarding (a) the Notes and distributions thereon and (b) the
Indenture.

 

5.            The
Transferee has knowledge in financial and business matters and is capable of evaluating the merits and risks of an investment in the Notes;
the Transferee has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision;
and the Transferee (or any account or which it is pursuing) is able to bear the economic risk of an investment in the Notes and can afford
a complete loss of such investment.

 

6.            The
Transferee is an “accredited investor” as defined in paragraph (1), (2), (3) or (7) of Rule 501(a) under
the 1933 Act.

 

7.            Either
(i) the Transferee is not, and is not acquiring, holding or transferring the Notes on behalf of or using assets of, an “employee
benefit plan” as defined in Section 3(3) of ERISA, a plan described in Section 4975(e)(1) of the Code, an entity
which is deemed to hold the assets of any such employee benefit plan or plan pursuant to 29 C.F.R. Section 2510.3-101, as modified
by Section 3(42) of ERISA (the “Plan Asset Regulations”), which employee benefit plan, plan or entity is subject
to Title I of ERISA or Section 4975 of the Code, or a governmental, non-U.S. or church plan which is subject to any U.S. federal,
state, local or other law that is substantially similar to Title I of ERISA or Section 4975 of the Code (“Similar Law”),
or (ii) (A) the Transferee is acquiring a Note, (B) as of the date of the transfer or purchase, it believes that such Note
is properly treated as indebtedness without substantial equity features for purposes of the Plan Asset Regulations and agrees to so treat
such Note and (C) the Transferee’s acquisition, holding and disposition of the Notes will satisfy the requirements of Prohibited
Transaction Class Exemption (“PTCE”) 84-14 (relating to transactions affected by a qualified professional asset
manager), PTCE 90-1 (relating to investments by insurance company pooled separate accounts), PTCE 91-38 (relating to investments in bank
collective investment funds), PTCE 95-60 (relating to transactions involving insurance company general accounts), PTCE 96-23 (relating
to transactions directed by an in-house professional asset manager) or the statutory prohibited transaction exemption for service providers
set forth in Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code or a similar class or statutory exemption and will
not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code (or, in the case of
a governmental, non-U.S. or church plan subject to Similar Law, will not violate any such substantially Similar Law).

 

8.            If
the Transferee is acquiring the Notes as a fiduciary or agent for one or more investor accounts, it represents that it has sole investment
discretion with respect to each such account and it has full power to make the foregoing acknowledgments, representations, warranties
and agreements on behalf of each such account.

 

    Exhibit B-1-7

     

    

 

The Transferee hereby further
acknowledges that:

 

(i)            the
rights of any Transferee will be subject and subordinate in all respects to all rights, powers, and prerogatives of Fannie Mae under the
Fannie Mae Lender Contract, and no Noteholder enjoys privity of contract with Fannie Mae or is entitled to any benefit under the Acknowledgment
Agreement except to the extent that the Indenture Trustee is entering into and shall perform under the Acknowledgment Agreement in its
capacity as Indenture Trustee for the benefit of the Noteholders;

 

(ii)           Fannie
Mae has the right to terminate the Servicer with or without cause and controls the process for the disposition of assets under the Acknowledgement
Agreement in the event of a termination of the Servicer or other transfer of MSRs; and

 

(iii)          pursuant
to the Fannie Mae Lender Contract, Fannie Mae has the right to offset liabilities owed to it subject to the Acknowledgment Agreement
against fees and compensation paid to the Servicer prior to any distribution of excess servicing to any Noteholder.

 

All capitalized terms used
but not otherwise defined herein have the respective meanings assigned thereto in the Indenture, pursuant to which the Notes were issued.

 

IN WITNESS WHEREOF, the undersigned
has caused this Transferee Certification to be executed by its duly authorized representative as of the day and year first above written.

3.            The

purposes of determining the aggregate amount of securities owned and/or invested on a discretionary basis by the Transferee, the Transferee
used the cost of such securities to the Transferee and did not include any of the securities referred to in the preceding paragraph. Further,
in determining such aggregate amount, the Transferee may have included securities owned by subsidiaries of the Transferee, but only if
such subsidiaries are consolidated with the Transferee in its financial statements prepared in accordance with generally accepted accounting
principles and if the investments of such subsidiaries are managed under the Transferee’s direction. However, such securities were
not included if the Transferee is a majority-owned, consolidated subsidiary of another enterprise and the Transferee is not itself a reporting

Transferee acknowledges that it is familiar with Rule 144A and understands that the Transferor and other parties related to the Notes

on Rule 144A.

                                                                                YES
	____

                                                                                NO
	 

 

If the answer to the foregoing
question is “NO”, the Transferee agrees that, in connection with any purchase of securities sold to the Transferee for the
account of a third party (including any separate account) in reliance on Rule 144A, the Transferee will only purchase for the account
of a third party that at the time is a “qualified institutional buyer” within the meaning of Rule 144A. In addition,
the Transferee agrees that the Transferee will not purchase securities for a third party unless the Transferee has obtained a current
representation letter from such third party or taken other appropriate steps contemplated by Rule 144A to conclude that such third
party independently meets the definition of “qualified institutional buyer” set forth in Rule 144A.

 

The Transferee will notify each of the parties
to which this certification is made of any changes in the information and conclusions herein. Until such notice is given, the Transferee’s
purchase of the Notes will constitute a reaffirmation of this certification as of the date of such purchase. In addition, if the Transferee
is a bank or savings and loan as provided above, the Transferee agrees that it will furnish to such parties updated annual financial statements
promptly after they become available.

Transferee is a “qualified institutional buyer” as that term is defined in Rule 144A (“Rule 144A”)
promulgated under the Securities Act of 1933, as amended (the “1933 Act”), because (a) the Transferee is an investment

Act”) and (b) as marked below, the Transferee alone, or the Transferee’s Family of Investment Companies, owned at

investment adviser (or, in the case of a unit investment trust, the same depositor) or investment advisers (or depositors) that are affiliated

the other).

 

4.            The
term “securities” as used herein does not include (a) securities of issuers that are affiliated with the Transferee or

undersigned as of the date of such purchase.

Reference is hereby made to
the Base Indenture, dated as of April 28, 2021 (as may be amended, restated, supplemented or otherwise modified from time to time,
the “Indenture”), among PFSI ISSUER TRUST – FMSR, as Issuer, PennyMac Loan Services, LLC, as Administrator and
as Servicer, and Citibank, N.A., as Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary, Credit Suisse First
Boston Mortgage Capital LLC, as Administrative Agent, and the “Administrative Agents” from time to time party thereto. Capitalized
terms used but not defined herein shall have the meanings given to them in the Indenture.

 

    Exhibit B-2-6

     

    

 

The undersigned (the “Transferee”)
intends to purchase $________ Note Balance of Class __Notes (the “Notes”) from the Transferor named in the Transfer
Certificate to which this Transferee Certification is attached. In connection with the registration of the transfer of such Notes, the
Transferee hereby executes and delivers to each of you this “Transferee Certification” in which the Transferee certifies to
each of you the information set forth herein.

 

1.            The
Transferee (i) is acquiring such Notes in an offshore transaction in accordance with Rule 904 of Regulation S, (ii) is
acquiring such Notes for its own account, (iii) is not acquiring, and has not entered into any discussions regarding its acquisition
of, such Notes while it is in the United States of America or any of its territories or possessions, (iv) understands that such Notes
are being sold without registration under the Securities Act by reason of an exemption that depends, in part, on the accuracy of these
representations, (v) understands that such Notes may not, absent an applicable exemption, be transferred without registration and/or
qualification under the Securities Act and applicable state securities laws and the laws of any other applicable jurisdiction and (vi) understands
that prior to the end of the Distribution Compliance Period, interests in a Regulation S Note may only be held through Euroclear or Clearstream.

 

The Transferee understands
that the Notes have not been registered under the Securities Act and, therefore, cannot be offered or sold in the United States or to
U.S. persons (as defined in Rule 902(k) promulgated under the Securities Act) unless they are registered under the Securities
Act or unless an exemption from registration is available. Accordingly, the certificates representing the Notes will bear a legend stating
that the Notes have not been registered under the Securities Act and setting forth certain of the restrictions on transfer of the Notes.
The Transferee understands that the Issuer has no obligation to register the Notes under the Securities Act or to comply with the requirements
for any exemption from the registration requirements of the Securities Act.

 

The Transferee understands
that the Notes (or any interest therein) may be resold, pledged or transferred only (a) to a person whom the Transferee reasonably
believes after due inquiry is, and who has certified that it is, a “qualified institutional buyer” (a “QIB”)
that purchases for its own account or for the account of a QIB to whom notice is given that the resale, pledge or transfer is being made
in reliance on Rule 144A or (b) to a transferee that is a non-U.S. person acquiring such interest in an “offshore transaction”
(as defined in Regulation S) in compliance with the provisions of Regulation S, if the transfer is otherwise made in accordance with any
applicable securities laws of any state of the United States or any other relevant jurisdiction. In addition, such transfer may be subject
to additional restrictions and is subject to compliance with certain procedures, as set forth in Section 6.5 of the Indenture referred
to above.

 

The Transferee has been furnished
with all information that it requested regarding (a) the Notes and distributions thereon and (b) the Indenture.

 

The Transferee has knowledge
in financial and business matters and is capable of evaluating the merits and risks of an investment in the Notes; the Transferee has
sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision; and the Transferee
(or any account or which it is pursuing) is able to bear the economic risk of an investment in the Notes and can afford a complete loss
of such investment.

 

    Exhibit B-2-7

     

    

 

Either (i) the Transferee
is not, and is not acquiring, holding or transferring the Notes on behalf of or using assets of, an “employee benefit plan”
as defined in Section 3(3) of ERISA, a plan described in Section 4975(e)(1) of the Code, an entity which is deemed
to hold the assets of any such employee benefit plan or plan pursuant to 29 C.F.R. Section 2510.3-101, as modified by Section 3(42)
of ERISA (the “Plan Asset Regulations”), which employee benefit plan, plan or entity is subject to Title I of ERISA
or Section 4975 of the Code, or a governmental, non-U.S. or church plan which is subject to any U.S. federal, state, local or other
law that is substantially similar to Title I of ERISA or Section 4975 of the Code (“Similar Law”), or (ii) (A) as
of the date of the transfer or purchase, it believes that such Note is properly treated as indebtedness without substantial equity features
for purposes of the Plan Asset Regulations and agrees to so treat such Note and (B) the Transferee’s acquisition, holding and
disposition of the Notes will satisfy the requirements of Prohibited Transaction Class Exemption (“PTCE”) 84-14
(relating to transactions affected by a qualified professional asset manager), PTCE 90-1 (relating to investments by insurance company
pooled separate accounts), PTCE 91-38 (relating to investments in bank collective investment funds), PTCE 95-60 (relating to transactions
involving insurance company general accounts), PTCE 96-23 (relating to transactions directed by an in-house professional asset manager)
or the statutory prohibited transaction exemption for service providers set forth in Section 408(b)(17) of ERISA and Section 4975(d)(20)
of the Code or a similar class or statutory exemption and will not result in a non-exempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code (or, in the case of a governmental, non-U.S. or church plan subject to Similar Law, will not
violate any such substantially Similar Law).

 

The Transferee hereby further
acknowledges that:

 

(i)            the
rights of any Transferee will be subject and subordinate in all respects to all rights, powers, and prerogatives of Fannie Mae under the
Fannie Mae Lender Contract, and no Noteholder enjoys privity of contract with Fannie Mae or is entitled to any benefit under the Acknowledgment
Agreement except to the extent that the Indenture Trustee is entering into and shall perform under the Acknowledgment Agreement in its
capacity as Indenture Trustee for the benefit of the Noteholders;

 

(ii)            Fannie
Mae has the right to terminate the Servicer with or without cause and controls the process for the disposition of assets under the Acknowledgement
Agreement in the event of a termination of the Servicer or other transfer of MSRs; and

 

(iii)            pursuant
to the Fannie Mae Lender Contract, Fannie Mae has the right to offset liabilities owed to it subject to the Acknowledgment Agreement against
fees and compensation paid to the Servicer prior to any distribution of excess servicing to any Noteholder.

 

All capitalized terms used
but not otherwise defined herein have the respective meanings assigned thereto in the Indenture, pursuant to which the Notes were issued.

the Stop-Loss Cap, the Servicer SDQ Rate and the unpaid principal balance of SDQ Loans with respect to Mortgage Loans in the Servicer’s

 “Non SDQ Factor”. For the avoidance of doubt, if a borrower reinstates or resolves any Forbearance Loan and such loan subsequently
becomes ninety (90) days or more delinquent, the full unpaid principal balance of such SDQ Loan will be multiplied by the applicable “SDQ
Factor” and the 30% factor shall not be applicable unless additional forbearance of such loan under the CARES ACT or any replacement
thereof is permitted by Fannie Mae.
