(ix) the Trust Accounts and all amounts and property on deposit or credited to the Trust Accounts (excluding any investment

(x) any rights in the Dedicated Account and to the amounts on deposit therein; 

(xi) all other monies, securities, reserves and other property now or at any time in the possession of the Indenture Trustee or

and every kind, and other forms of obligations and receivables, instruments and other property which at any time constitute all or part of or are included in the proceeds of any of the foregoing. 

The Security Interest in the Trust Estate is Granted to secure the Notes issued pursuant to this Base Indenture (and the obligations under
this Base Indenture and any Indenture Supplement) equally and ratably without prejudice, priority or distinction between any Note and any other Note by reason of difference in time of issuance or otherwise, except as otherwise expressly provided in
this Base Indenture or in any Indenture Supplement, and to secure (1) the payment of all amounts due on such Notes, (2) the payment of all other sums payable by the Issuer under this Base Indenture or any Indenture Supplement and
(3) compliance by the Issuer with the provisions of this Base Indenture or any 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: 

  
 3 








 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 Corp. (the “Servicer”), PennyMac Holdings, LLC, PennyMac
Mortgage Investment Trust and Citibank, N.A., solely as Indenture Trustee under the Base Indenture, dated December 20, 2017, 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, the Servicer and PennyMac Holdings, LLC, 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. 
 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. 

AGREEMENTS OF THE PARTIES

delivered, and in consideration of the premises and the purchase of Notes by the Noteholders thereof, it is mutually covenanted and agreed as set forth in this Base Indenture, for the equal and proportionate benefit of all Noteholders of the Notes

 (f) in the computation of periods of time from a specified date to a later specified date,
unless otherwise specified herein, the words “commencing on” mean “commencing on and including,” the word “from” means “from and including” and the words “to” and “until” each means
“to but excluding”; 
 (g) periods of days referred to in this Base Indenture shall be counted in days unless Business Days are

	Section 1.3.	Compliance Certificates and Opinions. 

 Upon any application or request by the
Issuer to the Indenture Trustee to take any action under any provision of this Base Indenture, the Issuer will furnish to the Indenture Trustee (1) an Officer’s Certificate stating that all conditions precedent, if any, provided for in
this Base Indenture relating to the proposed action have been complied with and (2) except as provided below, an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with,
except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Base Indenture relating to such particular application or request, no additional certificate or
opinion need be furnished. No such certificate or opinion shall be required in any instance where 100% of the Noteholders have consented to the related amendment, modification or action and all of the Noteholders have directed the Indenture Trustee
in writing to execute such amendment or supplement, or with respect to any other modification or action, directed the Indenture Trustee in writing to permit such modification or action without receiving such certificate or opinion. 

Every certificate with respect to compliance with a condition or covenant provided for in this Base Indenture will include: 

(a) a statement to the effect that each individual signing such certificate has read such covenant or condition and the definitions herein
relating thereto; 
 (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or
opinions contained in such certificate are based; 
 (c) a statement to the effect that such individual has made such examination or
investigation as is necessary to express an informed opinion as to whether or not such covenant or condition has been complied with; and 

(d) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 

 

	Section 1.4.	Form of Documents Delivered to Indenture Trustee. 

 In any case where several
matters are required to be certified by, or covered by an opinion of, one or more specified Persons, one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to the other matters, and any such
Person may certify or give an opinion as to such matters in one or several documents. 

  
 6 








 Any certificate or opinion of the Issuer may be based, insofar as it relates to legal matters,
upon a certificate or opinion of, or representations by, counsel, unless the Issuer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations are erroneous. 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 of the
Issuer, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations are erroneous. 

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. 

  
 7 








 (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. 
 (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: Citibank, N.A., Corporate and Investment
Banking, 388 Greenwich Street, 14th Floor, New York, NY 10013, Attention: PMT ISSUER TRUST – FMSR Collateralized Notes, email: valerie.delgado@citi.com; (ii) in the case of Servicer and Administrator: 3043 Townsgate Road, Suite 300,
Westlake Village, CA 91361, Attention: PMT ISSUER TRUST – FMSR Collateralized Notes, email: pamela.marsh@pnmac.com; josh.smith@pnmac.com; contract.finance@pnmac.com (with a copy to Chris Gavin, Esq., Cadwalader, Wickersham & Taft LLP,
200 Liberty Street, New York, NY 10281, email: chris.gavin@cwt.com); (iii) in the case of the Issuer: to the Administrator (with copy to: Wilmington Savings Fund Society, FSB, as Owner Trustee, 500 Delaware Avenue, 11th Floor, Wilmington, Delaware
19801, Attention: 

  
 8 








 
Corporate Trust Administration, email: jeverhart@christianatrust.com); (iv) in the case of CSFB, as Administrative Agent: Eleven Madison Avenue, New York, NY 10010, email:
dominic.obaditch@credit-suisse.com; or (v) in any case at any other address previously furnished in writing by any such party to the other parties hereto. 

(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 PMC, and as specified in the related Indenture Supplement, and if no Outstanding Class is being so rated, including in the event ratings unsolicited by
PMC 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 or otherwise, 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. 

(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


  
 10 








 
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. 
 (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.

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. PMC, 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.

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 

  
 17 








 
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 Base Indenture at its offices at the Corporate Trust Office (in the case of the Indenture Trustee) or 3043 Townsgate Road, Suite 300, Westlake Village, 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. 
  

	Section 2.4.	Application of Trust Money. 

 All money deposited with the Indenture Trustee or
the Paying Agent pursuant to Section 4.2 shall be held in trust and applied by the Indenture Trustee or the Paying Agent, as the case may be, in accordance with the provisions of the Notes and this Base Indenture, to the
payment to the Persons entitled thereto, of the principal, interest, fees, costs and expenses (or payments in respect of the Funding Amount or other amount) for whose payment such money has been deposited with the Indenture Trustee or the Paying
Agent.

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

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).

	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


  
 29 








 
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. 
 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.

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 Investments. Such compensation is not payable or reimbursable under this Base Indenture. 

The State of New York is the Securities Intermediary’s jurisdiction for purposes of the UCC, and the laws of the State of New York are

	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. 
 (b) Payment Dates. On each Payment Date, the Indenture
Trustee shall transfer from the Collection and Funding Account to the Note Payment Account all 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 1:00 p.m. New York
City time on the 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. 

  
 31 








 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 the Sold MSR Portfolio, as applicable, or (ii) increases in the value of the MSRs that underlie the Retained MSR Portfolio and the Sold MSR Portfolio. By no later than 1:00 p.m. New York City time on the 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. 

(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 one Series with Outstanding Variable Funding Notes, VFN Draws on such
Funding Date shall be made on a pro rata basis among all applicable Outstanding Series of VFNs in their Revolving Periods based on their respective available Borrowing Capacities, unless otherwise provided in the related Indenture Supplement
and any applicable Note Purchase Agreement. If any VFN Funding Source does not fund its share of a requested VFN Draw, one or more other VFN Funding Sources may fund all or a portion of such draw, but no other VFN Funding Source shall have any
obligation to do so. Draws on VFNs of different Classes within the same Series need not be drawn pro rata relative to each other. 

  
 32 








 (c) Payment of Funding Amounts. 

(i) Subject to its receipt of a duly executed Funding Certification from the Administrator pursuant to
Section 4.3(a) stating that all Funding Conditions have been satisfied, and approval by the Administrative Agent in its sole discretion, the Indenture Trustee shall remit to the Issuer (or the Issuer’s designee), by
the close of business New York City time on each Funding Date, the amount of the aggregate Funding Amount on such Funding Date without causing the related VFN Principal Balance to exceed either (I) the related Maximum VFN Principal Balance or
(II) the amount that would cause a Borrowing Base Deficiency. 
 (ii) Subject to its receipt of a duly executed Funding
Certification from the Administrator pursuant to Section 4.3(a) indicating that all Funding Conditions have been satisfied, the Indenture Trustee shall remit to the Issuer (or the Issuer’s designee) by the close of
business on each Interim Payment Date or Payment Date occurring at any time when not all Outstanding Notes are in Full Amortization Periods, the amount of the aggregate Funding Amount to be funded on such Interim Payment Date or Payment Date, using
any amounts funded by VFN Funding Sources in respect of such Funding Amount as described in Section 4.3(b). 
 (d)
To the extent the Issuance Date for any Series of Term Notes occurs on a Business Day other than a Payment Date or an Interim Payment Date, the Indenture Trustee shall pay the proceeds of any such issuance in accordance with the flows of funds
provided to the Indenture Trustee at the joint written direction of the Administrator and the Administrative Agent, with the consent of each VFN Noteholder, so long as the Administrator and the Administrative Agent confirm in such direction
(x) that the specified flow of funds is correct; (y) whether there will be an Additional Note Payment made or deemed to have been made in connection with the issuance of such Series, and after giving effect to such payment, if any, the
amount of VFN Principal Balance; and (z) that after giving effect to the payment of amounts in accordance with the specified flow of funds and the reduction of the VFN Principal Balance, if any, no Borrowing Base Deficiency will exist. No
consent or instruction of any Holder of any Series of Term Notes shall be required in connection with payment amounts in accordance such joint written direction for any Series of Term Notes.

of each Outstanding Class of VFNs pro rata, based on their respective Note Balances, such amount as may be designated by the Administrator. 
  

	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. 

  
 39 








 (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. 
 (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 PMC 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 

  
 40 








 
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 PMC as holder of the Owner Trust Certificate. Amounts paid to PMC 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.

 (b) Expense Reserve Account. 

(i) Pursuant to Section 4.1, the Indenture Trustee shall establish and maintain an Expense Reserve
Account, which shall be an Eligible Account, for the benefit of the Indenture Trustee and the MSR Valuation Agent. 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 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 

  
 41 








 
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 PMC as holder of the Owner Trust Certificate. Amounts paid to PMC
or its designee pursuant to the preceding sentence shall be released from the Security Interest. 
 (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 and Funding Account; Eligible Securities Account. 

 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 shall be an Eligible Account, for the benefit of the Secured Parties. If
any such account loses its status as an Eligible Account, the 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; provided, however, if no such direction is provided, all amounts shall remain uninvested. 

  
 42 









	Section 4.8.	Note Payment Account. 

 (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 the extent that (i) the Issuer shall remit to the Indenture Trustee the Redemption Amount for a Class of
Notes pursuant to Section 13.1, (ii) the Indenture Trustee shall remit thereto any Available Funds from the Collection and Funding Account pursuant to Section 4.2(b), (iii) the Indenture Trustee
shall transfer amounts from an applicable Series Reserve Account pursuant to, and to the extent required by, Section 4.6, and (iv) the Indenture Trustee shall transfer amounts from the Expense Reserve Account pursuant
to, and to the extent required by, Section 4.6. 
 (b) On each Payment Date, an amount equal to the aggregate of
amounts described in Section 4.5(a) shall be withdrawn from the Note Payment Account by the Indenture Trustee and remitted to the Noteholders and other Persons or accounts described therein for payment as described in that
Section, and upon payments of all sums payable hereunder as described in Section 4.5(a), as applicable, any remaining amounts then on deposit in the Note Payment Account shall be released from the Security Interest and paid
to PMC or its designee unless it would cause a Borrowing Base Deficiency. 
 (c) Amounts held in the Note Payment Account may be invested in
Permitted Investments at the direction of the Administrator as provided in Section 4.1. 
  

	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; 

  
 43 








 (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 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. 
 (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. 

  
 44 








 (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 PMC 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. 
 (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. 

  
 45 








 (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.

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. 

  
 46 








 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. 
 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 be held by the Indenture Trustee as custodian for the Depository, if so specified in the related Indenture Supplement or Depository
Agreement), (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 

  
 48 








 
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. 
 (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. 

  
 49 








 (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. 

(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. 

  
 50 








 (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.

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.

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.

Trustee’s own rights, duties or immunities under the Notes and this Base Indenture. 
 (f) Unless otherwise provided in the form of Note

 54 









	Section 6.4.	Temporary Notes. 

 (a) Pending the preparation of definitive Notes of any Series
or Class, the Issuer may execute, and, upon receipt of the documents required by Section 6.3, together with an Issuer’s Certificate, the Indenture Trustee will authenticate and deliver, temporary Notes which are

substitutions and other variations as the Issuer may determine, as evidenced by the Issuer’s execution of such Notes. 
 (b) If
temporary Notes of any Series or Class are issued, the Issuer will cause permanent Notes of such Series or Class to be prepared without unreasonable delay. After the preparation of permanent Notes, the temporary Notes of such Series or

	Section 6.5.	Registration, Transfer and Exchange. 

 (a) Note 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. 

  
 55 








 (b) Exchange of Notes. Subject to Section 5.4, upon surrender

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. 

(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
(“STAMP”). 
 (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 S Note or of a beneficial therein shall be deemed by accepting such Note or beneficial interest, to have made all the certifications, 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: 

  
 56 








 (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). 

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 owners who are not “U.S. persons” (as such term is defined in Regulation S) in accordance with the rules and regulations of Euroclear or Clearstream) and the transfer restrictions contained in the legend on such Global Note and
exchanges or transfers of interests in a Global Note may be made only in accordance with the following: 
 (i) General

beneficial interest in a Rule 144A Global Note related to a Series and/or Class deposited with or on behalf of the Depository wishes at any time to exchange its interest in such Rule 144A Global Note for an interest in a Regulation S Global
Note for that Series and/or Class, or to transfer its interest in such Rule 144A Global Note to a Person who wishes to take delivery thereof in the form of an interest in a Regulation S Global Note for that Series and/or Class, such Note Owner (or
transferee), provided such Note Owner (or transferee) is not a “U.S. person” (as such term is defined in Regulation S), may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest in
such Rule 144A Global Note for a beneficial interest in the Regulation S Global Note for that Series and/or Class. Upon the receipt by the Indenture Trustee of (A) instructions from the Depository directing the Indenture Trustee to cause to be
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 account to be credited with such increase and (C) a certificate (each, a “Regulation S Note Transfer Certificate”) in the form of Exhibit
B-2 hereto given by the Note Owner or its transferee stating that the exchange or transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes,
including the requirements that the Note Owner or its transferee is not a “U.S. person” (as such term is defined in Regulation S) and the transfer is made pursuant to and in accordance with Regulation S, then the Indenture Trustee and the
Note Registrar, shall reduce the principal amount of the Rule 144A 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, and shall instruct Euroclear or Clearstream, as applicable, concurrently with such reduction, to credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Regulation S Global Note for the related Series and/or Class equal to the reduction in the principal amount of the Rule 144A Global Note for the related Series and/or Class. 

(iii) Regulation S Global Note to Rule 144A Global Note. If an owner of a beneficial interest in a Regulation S Global
Note related to a Series and/or Class deposited with or on behalf of the Depository wishes at any time to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery thereof in the form of an interest in a
Rule 144A Global Note for such Series and/or Class, such owner’s transferee may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Rule 144A Global
Note for such Series and/or Class. Upon the receipt by the Indenture Trustee and the Note Registrar, of (A) instructions from the Depository directing the Indenture Trustee and the Note Registrar, to cause to be credited a beneficial interest
in a Rule 

  
 58 








 
144A Global Note in an amount equal to the beneficial interest in such Regulation S Global Note to be exchanged but not less than the minimum denomination applicable to such owner’s Notes
held through a Rule 144A Global Note, to be exchanged, such instructions to contain information regarding the participant account with the Depository to be credited with such increase, and (B) a certificate (each, a “Rule 144A Note
Transfer Certificate”) in the form of Exhibit B-1 hereto given by the transferee of such beneficial interest, then the Indenture Trustee will reduce 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 in the Rule 144A Global Note for the related Series and/or Class equal to the reduction in the principal amount of the Regulation S Global Note for the related Series and/or Class. 

(iv) Transfers of Interests in Rule 144A Global Note. An owner of a beneficial interest in a Rule 144A Global Note may
transfer such interest in the form of a beneficial interest in such Rule 144A Global Note in accordance with the procedures of the Depository without the provision of written certification.

hereof, an owner of a beneficial interest in a Regulation S Global Note for the related Series and/or Class deposited with or on behalf of a Depository may at any time transfer such interest for a Regulation S Definitive Note upon provision to
the Indenture Trustee, the Issuer and the Note Registrar of a Regulation S Note Transfer Certificate. 
 (vii) Rule 144A

Certificate shall be provided prior to the Indenture Trustee’s or Note Registrar’s registration of such Transfer. In the event of any Transfer of a Rule 144A Definitive Note, a Rule 144A Note Transfer Certificate shall be provided prior to
the Indenture Trustee’s or Note Registrar’s registration of such Transfer. 

  
 59 








 (k) ERISA Restrictions. Neither the Note Registrar nor the Indenture Trustee shall
register the Transfer of any Definitive Notes unless the prospective transferee has delivered to the Indenture Trustee and the Note Registrar a certification to the effect that either (i) it is not, and is not acquiring, holding or transferring
the Notes, or any interest therein, or 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., church or other 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 transfer or purchase, it believes that such Notes are properly treated as indebtedness without
substantial equity features for purposes of the Plan Asset Regulations and agrees to so treat such Notes and (B) the transferee’s acquisition, holding or disposition of the Notes or any interest therein will satisfy the requirements of

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,
statutory or administrative 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., church or other plan subject to such Similar Law, will not violate any such Similar Law). In the case of any Book-Entry Note, each transferee of such Note or any beneficial interest therein by virtue of
its acquisition of such Note will be deemed to represent either (i) or (ii) above. 
 (l) No Liability of Indenture Trustee for
Transfers. To the extent permitted under applicable law, the Indenture Trustee (in any of its capacities) shall be under no liability to any Person for any registration of transfer of any Note that is in fact not permitted by this
Section 6.5 or for making any payments due to the Noteholder thereof or taking any other action with respect to such Noteholder under the provisions of this Base Indenture so long as the transfer was registered by the
Indenture Trustee and the Note Registrar in accordance with the requirements of this Base Indenture. 
  

	Section 6.6.	Mutilated, Destroyed, Lost and Stolen Notes. 

 (a) If (1) any mutilated Note
is surrendered to the Indenture Trustee or the Note Registrar, or the Issuer, the Note Registrar or the Indenture Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and (2) there is delivered to the
Issuer, the Note Registrar or the Indenture Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Issuer, the Note Registrar or the Indenture Trustee that such Note has
been acquired by a protected purchaser, the Issuer may execute, and, upon receipt of the documents required by Section 6.3, together with an Issuer’s Certificate, the Indenture Trustee will authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note of like tenor, Series or Class, Stated Maturity Date and Initial Note Balance, bearing a number not contemporaneously Outstanding. 

  
 60 








 (b) In case any such mutilated, destroyed, lost or stolen Note has become or is about to become
due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such Note on a Payment Date in accordance with Section 4.5. 

(c) Upon the issuance of any new Note under this Section, the Issuer, the Indenture Trustee, or the Note Registrar may require the payment of a

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 request of the Issuer that will remain Outstanding after the new issuance that the new issuance will not have a Ratings Effect on any Outstanding Notes that are rated by such Note Rating Agency at the request of the Issuer 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 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 to Section 6.10(b)(ii) above;

any additional Notes of any Series or Class.

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 PMC or at PMC’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.

period of two (2) Business Days following written notice from the Indenture Trustee of such default; or 
 (b) the Issuer defaults in

 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 

(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),


  
 72 








 
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. 

  
 73 









	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). 

 

	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 

  
 74 








 
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 under the PMH 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. 

 

	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: 

  
 75 








 (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. 

(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. 

  
 76 








 (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 

  
 77 








 
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. 

 

	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 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. 
 (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. 

  
 78 








 (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. 
 (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 

  
 79 








 
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 PMC 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. 
 (l) Location of Chief Executive Office and Records. The chief executive office of the Issuer and the office
where Issuer maintains copies of its corporate records, is located at the offices of the Administrator at 3043 Townsgate Road, Suite 300, Westlake Village, CA, 91361; 

  
 80 








 
provided that, at any time after the Closing Date, upon thirty (30) days’ prior written notice to the Indenture Trustee and the Noteholders, the Issuer may relocate its
jurisdiction of formation, and/or its principal place of business and chief executive office, and/or the office where it maintains all of its records, to another location or jurisdiction, as the case may be, within the United States to the extent
that the Issuer shall have taken all actions necessary or reasonably requested by the Indenture Trustee or the Majority Noteholders of all Outstanding Notes to amend its existing financing statements and continuation statements, and file additional
financing statements and to take any other steps reasonably requested by the Indenture Trustee or the Majority Noteholders of all Outstanding Notes to further perfect or evidence the rights, claims or security interests of the Indenture Trustee and
the Noteholders under any of the Transaction Documents. 
 (m) Solvency. The Issuer: (i) is not “insolvent” (as such
term is defined in § 101(32)(A) of the Bankruptcy Code); (ii) is able to pay its debts as they become due; and (iii) does not have unreasonably small capital for the business in which it is engaged or for any business or transaction
in which it is about to engage. The Issuer is not Granting the Trust Estate to the Indenture Trustee with the intent to defraud, delay or hinder any of its creditors. 

(n) Separate Identity. The Issuer is operated as an entity separate from the Servicer and the Administrator. The Issuer has complied
with all covenants set forth in its Organizational Documents. 
 (o) Name. The legal name of the Issuer is as set forth in this Base
Indenture and the Issuer does not use and has not used any other trade names, fictitious names, assumed names or “doing business as” names. 

(p) Governmental Authorization. Other than the filing of the financing statements (or financing statement amendments) required hereunder
or under any other Transaction Document, no authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for (i) the due execution and delivery by Issuer of this Base
Indenture and each other Transaction Document to which it is a party and (ii) the performance of its obligations hereunder and thereunder. 

(q) Accuracy of Information. All information heretofore furnished by the Issuer or any of its Affiliates to the Indenture Trustee or the
Noteholders for purposes of or in connection with this Base Indenture, any of the other Transaction Documents or any transaction contemplated hereby or thereby is, and all such information hereafter furnished by the Issuer or any of its Affiliates
to the Indenture Trustee or the Noteholders will be, true and accurate in every material respect on the date such information is stated or certified. 

(r) Use of Proceeds. No proceeds of any issuance of Notes or funding under a VFN hereunder will be used for a purpose that violates, or
would be inconsistent with, Regulation T, U or X promulgated by the Board of Governors of the Federal Reserve System from time to time. 

  
 81 








 (s) Investment Company. The Issuer is not required to be registered as an “investment
company” within the meaning of the Investment Company Act, or any successor statute. 
 (t) Compliance with Law. The Issuer has
complied in all material respects with all applicable laws, rules, regulations, orders, writs, judgments, injunctions, decrees or awards to which it may be subject. 

(u) Investments. The Issuer does not own or hold, directly or indirectly (i) any capital stock or equity security of, or any equity
interest in, any Person or (ii) any debt security or other evidence of indebtedness of any Person. 
 (v) Transaction Documents.
The PC Repurchase Agreement is the only agreement pursuant to which the Issuer directly or indirectly purchases and receives contributions of Participation Certificates from PMC and the PC Repurchase Agreement represents the only agreement between
PMC and the Issuer relating to the transfer of the Participation Certificates from PMC to the Issuer. 
 (w) Limited Business. Since
its formation, the Issuer has conducted no business other than entering into and performing its obligations under the Transaction Documents to which it is a party, and such other activities as are incidental to the foregoing. The Transaction
Documents to which it is a party, and any agreements entered into in connection with the transactions that are permitted thereby, are the only agreements to which the Issuer is a party. 

 

	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. 

  
 82 








 (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. 
  

	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.

 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.

reserves with respect to any such tax, assessment, charge or levy so contested. 
 (e) Investments. The Issuer hereby covenants that
it will not, without the prior written consent of the Majority Noteholders of all Outstanding Notes, acquire or hold any indebtedness for borrowed money of another person, or any capital stock, debentures, partnership interests or other ownership

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.

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.

the filings required by this subsection, which deferral shall be granted at the sole discretion of Fannie Mae.

of, PMC in such notice. 
 (l) Fannie Mae Set Off Rights. PMC has no actual notice, including any notice received from Fannie Mae, or

Agent, the Paying Agent, the Securities Intermediary, the Disposition Manager, the Trust Estate, the Owner Trustee and the Noteholders (as applicable, with respect to the related Series of Notes) (each an “Indemnified Party”)
from and against any and all costs, expenses, losses, claims, damages and liabilities to the extent that such cost, expense, loss, claim, damage or liability arose out of, and was imposed upon, the Indenture Trustee, the Securities Intermediary, the
Note Registrar, the Disposition Manager, the Owner Trustee, the Calculation Agent, the Paying Agent, the Securities Intermediary, the Trust Estate or any Noteholder (i) in the case of indemnification by the Administrator, by reason of a
violation of law, gross negligence or willful misconduct of the Administrator (or of the Issuer as a result of a direction, act or omission by the Administrator), in the performance of their respective obligations under this Base Indenture and the
other Transaction Documents or (ii) in the case of indemnification by the Servicer, by reason of a violation of law, gross negligence or willful misconduct of the Servicer, in the performance of its respective obligations under this Base
Indenture and the other Transaction Documents or as servicer or subservicer under the Fannie Mae Lender Contracts, or by reason of the breach by the 

  
 99 








 
Servicer of any of its representations, warranties or covenants hereunder or under the Fannie Mae Lender Contracts; provided, that any indemnification amounts payable by the Administrator
or the Servicer, as the case may be, to the Owner Trustee hereunder shall not be duplicative of any indemnification amount paid by the Administrator to the Owner Trustee in accordance with the Trust Agreement or under the Administration Agreement.

 (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 PMC 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 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 Indemnified Parties. Each Indemnified Party, as a condition of the indemnity agreement contained herein, shall use its commercially reasonable efforts to cooperate with the Indemnifying Party in the defense of any
such action or claim. The Indemnifying Party shall not, without the prior written consent of any Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding or
threatened proceeding. 

  
 100 








 (c) Expenses. Indemnification under this Section shall include, without limitation,
reasonable fees and expenses of counsel and expenses of litigation (including such fees and expenses incurred in enforcing the Indemnifying Party’s right to indemnification). If the Indemnifying Party 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 Indemnifying Party, without interest. 

(d) Survival. The provisions of this Section 10.4 shall survive the resignation or removal of the Indenture
Trustee, the Calculation Agent and the Paying Agent and the termination of this Base Indenture. 
  

	Section 10.5.	Merger or Consolidation, or Assumption of the Obligations, of PMC.

which Person in any of the foregoing cases executes an agreement of assumption to perform every obligation of PMC under this Base Indenture, shall be the successor to PMC under this Base Indenture without the execution or filing of any paper or any
further act on the part of any of the parties to this Base Indenture; provided, however, that (i) if any of the Notes are then rated by a Note Rating Agency, then prior to any such merger, consolidation or conversion (1) PMC
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 PMC true sale as to the transfers
of the Participation Certificates from the Servicer to the Issuer and non-consolidation of the Servicer with the Issuer and security interest and tax and any additional opinions required under any related
Indenture Supplement; provided, further, that the conditions specified in clauses (i) and (ii) above shall not apply to any transaction (i) in which an Affiliate of PMC assumes the obligations
of PMC and otherwise satisfies the eligibility criteria applicable to the Servicer under the Fannie Mae Lender Contracts or (ii) in which an Affiliate of PMC is merged into or is otherwise combined with PMC and PMC is the sole survivor of such
merger or other combination. PMC shall provide notice of any merger, consolidation or succession pursuant to this Section to the Indenture Trustee, the Noteholders and each Note Rating Agency. 

Except as described in the preceding paragraph, PMC may not assign or delegate any of its rights or obligations under this Base Indenture or
any other Transaction Document.

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

Sections 8.7 and 8.8; 

  
 102 








 (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.

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

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. 

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. 

  
 110 








 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. 
 (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.


  
 112 








 
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. 

 

	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


  
 113 








 
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 give
notice 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. 

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.

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

Series or Classes of Notes, stating that such covenants are expressly being included or such surrenders are expressly being made solely for the benefit of one or more specified Series or Classes); 

(iii) to cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision
herein, or to make any other provisions with respect to matters or questions arising under this Base Indenture;

 (viii) to prevent the Issuer from being subject to tax on its net income as an
association (or publicly traded partnership) taxable as a corporation or a taxable mortgage pool taxable as a corporation, each for United States federal income tax purposes; 

(ix) determined by the Administrator to be reasonably necessary to maintain the rating currently assigned by the applicable
Note Rating Agency and/or to avoid such Class of Notes being placed on negative watch by such Note Rating Agency; or 

(x) as otherwise provided in the related Indenture Supplement. 

(b) Additionally, subject to the terms and conditions of Section 12.2, unless otherwise provided in the related
Indenture Supplement with respect to any amendment of this Base Indenture or an Indenture Supplement, and in addition to clauses (i) through (x) above, this Base Indenture or an Indenture Supplement may also be
amended by the Issuer, the Indenture Trustee, the Administrator, the Servicer and the Administrative Agent (in its sole and absolute discretion) without the consent of any of the Noteholders or any other Person, upon delivery of an Issuer Tax
Opinion, unless such Issuer Tax Opinion is waived by (i) in the case of an amendment to such Indenture Supplement the Series Required Noteholders of such Series or (ii) in the case of an amendment to this Base Indenture, the Series
Required Noteholders of each Outstanding Series, 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 Noteholders of the
Notes under this Base Indenture or any other Transaction Document; provided, however, that (i) the Issuer shall deliver to the Indenture Trustee an Officer’s Certificate to the effect that the Issuer reasonably believes that

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 amendment to the related Note Rating Agency and
(b) each Administrative Agent shall have provided their prior written consent to such amendment. 
 (c) Any amendment of this Base
Indenture which affects the rights, duties, immunities, obligations or liabilities of the Owner Trustee in its capacity as owner trustee under the Trust Agreement shall require the written consent of the Owner Trustee. 

 

	Section 12.2.	Supplemental Indentures and Amendments with Consent of Noteholders. 

 In addition
to any amendment permitted pursuant to Section 12.1, and subject to the terms and provisions of each Indenture Supplement with respect to any amendment to this Base Indenture or such Indenture Supplement, with prior notice
to each Note Rating Agency and the consent of the Majority Noteholders of each Series materially and adversely affected by such amendment of this Base Indenture, including any Indenture Supplement, by Act of said Noteholders delivered to the Issuer
and the Indenture Trustee, the Issuer, the Administrator, the Servicer, the Administrative Agent and the Indenture Trustee upon delivery of an Issuer Tax 

  
 117 








 
Opinion (unless the Noteholders unanimously consent to waive such opinion), may enter into an amendment of this Base Indenture for the purpose of adding any provisions to, or changing in any
manner or eliminating any of the provisions of, this Base Indenture of modifying in any manner the rights of the Noteholders of the Notes of each such Series or Class under this Base Indenture or any Indenture Supplement; provided,
however, that no such amendment will, without the consent of the Noteholder of each Outstanding Note materially and adversely affected thereby: 

(a) change the scheduled payment date of any payment of interest on any Note held by such Noteholder, or change a Payment Date or Stated
Maturity Date (other than the exercise of an optional extension as set forth in the related Indenture Supplement) of any Note held by such Noteholder; 

(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, or change the method of computing the Note Balance or Note Interest Rate in a manner that is adverse to such Noteholder; 

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

(d) reduce the percentage of Noteholders of the Outstanding Notes (or of the Outstanding Notes of any Series or Class), whose consent is
required for any such amendment, or whose consent is required for any waiver of compliance with the provisions of this Base Indenture or any Indenture Supplement or of defaults hereunder or thereunder and their consequences, provided for in this
Base Indenture or any Indenture Supplement; 
 (e) modify any of the provisions of this Section or Section 8.14,

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; 
 (h) increase any Advance Rates in respect of Notes

 (i) change, modify or waive any Scheduled Principal Payment

Noteholders of the Notes of the related Series upon delivery of all opinions and certificates and notice to each Note Rating Agency required pursuant to the first paragraph of this Section 12.2 or as otherwise specified in
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. 

  
 118 








 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. 
  

	Section 12.3.	Execution of Amendments. 

 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. No such Opinion of Counsel shall be required in connection with any amendment or Indenture Supplement consented to by all Noteholders if all of the Noteholders have directed the Indenture Trustee in
writing to execute such amendment or Indenture Supplement. The Indenture Trustee may, but will not be obligated to, enter into any such amendment or Indenture Supplement which affects the Indenture Trustee’s own rights, duties or immunities
under this Base Indenture or otherwise. 
  

	Section 12.4.	Effect 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 Base Indenture and the related Indenture Supplement will be modified in accordance therewith with respect to each Series and
Class of 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 Indenture Supplement for all purposes; and every Noteholder of Notes theretofore or thereafter
authenticated and delivered hereunder will be bound thereby to the extent provided therein. 
  

	Section 12.5.	Reference in Notes to Indenture Supplements. 

 Notes authenticated and delivered
after the execution of any amendment of this Base Indenture or any Indenture Supplement or any supplemental indenture pursuant to this Article may, and will if required by the Indenture Trustee, bear a notation in form approved by the Indenture
Trustee as to any 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 the Issuer and authenticated and delivered by the Indenture Trustee in exchange for Outstanding Notes. 

  
 119 









	Section 12.6.	Amendments to Appendix A 

 Any amendment of Appendix A to this Base
Indenture which affects the rights, duties, immunities, obligations or liabilities of any party to this Base Indenture or to any other Transaction Document shall require the written consent of such party. 

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 five (5) days 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. 

  
 120 








 (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. 
 (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 ten (10) days prior to the end of such Revolving
Period or at other times specified in the related Indenture Supplement upon ten (10) 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 (the
“Redemption Date”). 
 (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 (Collections for this
purpose include payments of the PMH Repurchase Price), upon one (1) 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. 

  
 121 








 (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 

  
 122 








 
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. 
  

	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. 

  
 123 








 (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 PMC has the right to
withdraw the Base Servicing Fee with respect to any Portfolio Mortgage Loan out of collections it receives with respect to such Portfolio Mortgage Loan. 
  

	Section 14.8.	Owner Trustee Limitation of Liability. 

 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. 

  
 124 









	Section 14.9.	Communications with Rating Agencies. 

 If the Servicer, the Administrative 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. 

 

	Section 14.10.	Authorized Representatives. 

 Each individual designated as an authorized
representative of the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary, PMC, the Administrative Agents and the Issuer (each, an “Authorized Representative”), is authorized to give and receive
notices, requests and instructions and to deliver certificates and documents in connection with this Base Indenture on behalf of each of the Indenture Trustee, Calculation Agent, Paying Agent, Securities Intermediary, PMC, PLS, the Administrative
Agents and the Issuer, respectively, and the specimen signature for each such Authorized Representative of the Indenture Trustee, Calculation Agent, Paying Agent, Securities Intermediary, PMC, the Administrative Agents and the Issuer initially
authorized hereunder is set forth on Exhibits C-1, C-2, C-3 and
C-4, respectively. From time to time, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities Intermediary, PMC, PLS, the Administrative Agents and the Issuer may, by delivering
to the others a revised exhibit, change the information previously given pursuant to this Section 14.10, but each of the parties hereto shall be entitled to rely conclusively on the then current exhibit until receipt of a
superseding exhibit. 

  
 125 









	Section 14.11.	Performance of the Issuer’s Duties by the Owner Trustee and the Administrator. 


(a) The parties hereto hereby acknowledge and agree (i) that certain duties of the Issuer will be performed on behalf of the Issuer by the
Administrator pursuant to the Administration Agreement and hereby acknowledge and accept the terms of such agreement as of the date hereof and (ii) except as expressly set forth herein, the Owner Trustee shall have no duty or obligation to
perform the obligations of the Issuer hereunder or to monitor the compliance of the Issuer with the terms hereof. 
 (b) Any successor to the
Owner Trustee appointed pursuant to the terms of the Trust Agreement (or any corporation into which the Owner Trustee may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the
Owner Trustee shall be a party) shall be the successor Owner Trustee under the Trust Agreement for purposes of this Base Indenture without the execution or filing of any paper, instrument or further act to be done on the part of the parties hereto.

  

	Section 14.12.	Noteholder or Note Owner Communications with the Indenture Trustee. 

 A Noteholder
(if the Notes are represented by Definitive Notes) or a Note Owner (if the Notes are represented by Book-Entry Notes) may communicate with the Indenture Trustee and give notices and make requests and demands and give directions to the Indenture
Trustee through the procedures of the Depository and by notifying the Indenture Trustee and providing to the Indenture Trustee a copy of the communication such Noteholder or Note Owner, as applicable, proposes to send. Any Note Owner must provide
written certification stating that the Note Owner is a beneficial owner of a Note, together with supporting documentation such as a trade confirmation, an account statement, a letter from a broker or dealer 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 security or
indemnity reasonably satisfactory to the Indenture Trustee to protect it against the fees and expenses that it may incur in complying with the request, demand or direction.

duly endorsed by, 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

cover any tax or other governmental charge that may be imposed in connection with any such registration of 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

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-1-9 








 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


  
 Exhibit A-1-10 








 
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.

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.

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

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.

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

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.

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 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. 

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.

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

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

Reference is hereby made to the Base Indenture, dated as of December [20], 2017 (as may be amended, restated, supplemented or otherwise
modified from time to time, the “Indenture”), among PMT ISSUER TRUST—FMSR, as Issuer, PennyMac Corp., as Administrator and as Servicer, and Citibank, N.A., as Indenture Trustee, Calculation Agent, Paying Agent and Securities

the Indenture. 
 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. 

  
 Exhibit B-1-5 








 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. 

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. 

  
 Exhibit B-1-6 








 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. 
 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.

2. The Transferee is a “qualified institutional buyer” as that term is defined in Rule 144A (“Rule 144A”) promulgated under

shall be deemed to be a separate investment company) that have the same investment adviser (or, in the case of a unit investment trust, the same depositor) or investment advisers (or depositors) that are affiliated (by virtue of being majority-owned
subsidiaries of the same parent or because one investment adviser is a majority-owned subsidiary of the other). 
 4. The term
“securities” as used herein does not include (a) securities of issuers that are affiliated with the Transferee or are part of the Transferee’s Family of Investment Companies, (b) bank deposit notes and certificates of
deposit, (c) loan participations, (d) repurchase agreements, (e) securities owned but subject to a repurchase agreement and (f) currency, interest rate and commodity swaps.

 Reference is hereby made to the Base Indenture,
dated as of December [20], 2017 (as may be amended, restated, supplemented or otherwise modified from time to time, the “Indenture”), among PMT ISSUER TRUST—FMSR, as Issuer, PennyMac Corp., as Administrator and as Servicer, and

 Exhibit B-2-5 








 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. 

2. 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.

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. 

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. 

  
 Exhibit B-2-6 








 6. Either (i) the Transferee is not, and is not acquiring, holding or transferring the Notes

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

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). 

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