Seller whose name is set forth on the cover page hereof (“Seller”). 
 
RECITALS 
 
WHEREAS, the Participant and the Seller are parties to the Mortgage Loan Participation Agreement, dated as of December 24, 1996 (the “Original Participation Agreement”); 
 
WHEREAS, pursuant to the Original Participation Agreement,
Seller desired to sell to Participant from time to time Participation Certificates (as defined in the Original Participation Agreement) evidencing 100% undivided ownership interests in certain Mortgage Loans (as defined in the Original Participation
Agreement) eligible in the aggregate to back Securities (as defined in the Original Participation Agreement) with the terms described in related Take-Out Commitments (as defined in the Original Participation Agreement); 
 
WHEREAS, pursuant to the Original Participation Agreement,
Participant desired and may have in its sole discretion purchased such Participation Certificates from Seller in accordance with the terms and conditions set forth in the Original Participation Agreement; 
 
WHEREAS, pursuant to the Original Participation Agreement,
Participant’s willingness to purchase any Participation Certificate (as defined in the Original Participation Agreement) evidencing particular Mortgage Loans (as defined in the Original Participation Agreement) was based on Participant’s
expectation, in reliance upon Seller’s representations and warranties in the Original Participation Agreement, that such Mortgage Loans (as defined in the Original Participation Agreement) in the aggregate, constituted a pool or pools of
mortgage loans that were eligible to back a Security (as defined in the Original Participation Agreement) and that the Security (as defined in the Original Participation Agreement), in the amount and with the terms described in the related Take-Out
Commitment (as defined in the Original Participation Agreement), will be issued and Participant will receive delivery thereof within the time period agreed upon between Participant and Seller and reflected in the terms of such Participation
Certificate (as defined in the Original Participation Agreement); 
 
WHEREAS, pursuant to the Original Participation Agreement, the amount of the Purchase Price (as defined in the Original Participation Agreement) and the Performance Fee (as defined in the Original Participation Agreement) to
be paid by Participant to Seller with respect to each Participation Certificate (as defined in the Original Participation Agreement) was to be calculated on the expectation of Participant, based upon the representations and warranties of the Seller
therein, that Participant would receive delivery of the Security (as defined in the Original Participation Agreement) to be backed by the Mortgage Loans (as defined in the Original Participation Agreement) evidenced by the Participation Certificate
(as defined in the Original Participation Agreement) purchased by Participant on the specified Anticipated Delivery Date (as defined in the Original Participation Agreement) and that failure to receive such delivery 

would result in a material decrease in the market value of the Participation Certificate (as defined in the Original Participation Agreement)
and the underlying Mortgage Loans (as defined in the Original Participation Agreement) considered as a whole; 
 
WHEREAS, the Seller and the Participant desire to amend and restate the Original Participation Agreement as provided herein; 
 
NOW THEREFORE, for good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties hereto hereby agree that the Original Participation Agreement be amended and restated in its entirety as follows: 
 
PRELIMINARY STATEMENT 
 
Seller desires to sell to Participant from time to time Participation Certificates evidencing a 100%
undivided ownership interest in certain Mortgage Loans eligible in the aggregate to back Securities with the terms described in related Take-Out Commitments. 
 
Participant desires and may in its sole discretion purchase such Participation Certificates from Seller in accordance with the terms and
conditions set forth in this Agreement. Seller, subject to the terms hereof, will cause (a) Mortgage Loans evidenced by a Participation Certificate to back a GNMA Security issued by Seller and guaranteed by GNMA, a FNMA Security issued and
guaranteed by FNMA or a FHLMC Security issued and guaranteed by FHLMC and (b) Delivery of such GNMA Security, FNMA Security or FHLMC Security by GNMA, FNMA or FHLMC to Participant or its designee, which GNMA Security, FNMA Security or FHLMC Security
will be purchased by a Takeout Investor. 
 
Participant’s willingness to purchase any Participation Certificate evidencing particular Mortgage Loans is based on Participant’s expectation, in reliance upon Seller’s representations and warranties herein, that such
Mortgage Loans in the aggregate, constitute a pool or pools of mortgage loans that are eligible to back a Security and that the Security, in the amount and with the terms described in the related Take-Out Commitment, will be issued and Participant
will receive Delivery thereof within the time period agreed upon between Participant and Seller and reflected in the terms of such Participation Certificate. 
 
The amount of the Purchase Price and the Performance Fee to be paid by Participant to Seller with respect to each Participation
Certificate will be calculated on the expectation of Participant, based upon the representations and warranties of the Seller herein, that Participant will receive Delivery of the Security to be backed by the Mortgage Loans evidenced by the
Participation Certificate purchased by Participant on the specified Anticipated Delivery Date and that failure to receive such Delivery will result in a material decrease in the market value of the Participation Certificate and the underlying
Mortgage Loans considered as a whole. During the period from the purchase of a Participation Certificate to Delivery of the related Security, Participant expects to rely entirely upon Seller to service the Mortgage Loans evidenced by the applicable
Participation Certificate, it being acknowledged that the continued effectiveness of Seller’s Agency Approvals during such period constitutes an essential factor in the calculation by Participant of the Purchase Price and the Performance Fee
paid to Seller for the related Participation Certificate and that loss of such Agency Approvals by Seller would

owed by Participant to Seller upon issuance of such Security in the circumstances contemplated in Section 3(c)(2). Except as otherwise provided in this Section 3(a)(3) and in Section 3(b), and subject to Participant’s right of set-off set forth
in Section 3(g), any Performance Fee owed by Participant with respect to a Participation Certificate shall be paid by Participant to Seller not later than the Settlement Date of the related Security. It is understood by Seller and Participant that,
if Seller requests and Participant agrees to pay the Performance Fee prior to the Settlement Date of the related Security, the amount of such Performance Fee shall be adjusted as mutually agreed by Seller and Participant. 
 
(b) Unless Receipt of a Security backed by the Mortgage Loans
evidenced by a Participation Certificate purchased hereunder has occurred by 12:00 noon, New York City time, on the related Settlement Date, (1) the Performance Fee relating to such Participation Certificate shall be reduced daily for the period
from the Settlement Date to but not including the earlier of the date of Receipt of such Security and the date of satisfaction of the obligations of Seller pursuant to the exercise by Participant of any remedial election authorized by this Section 3
by an amount equal to (A) the Purchase Price of such Participation Certificate multiplied by (B) the result obtained by dividing (i) the Pass-Through Rate for such Participation Certificate plus one percent by (ii) three hundred and sixty (360) and
(2) the Performance Fee, if any, relating to such Participation Certificate shall not be payable until the end of the period specified in clause (1) of this paragraph. 
 
(c) (1) If a breach by Seller of this Agreement results in any Mortgage Loan being a Defective Mortgage Loan
at the time of the delivery of the related Participation Certificate to Participant, Participant in its sole discretion may require that Seller, upon receipt of 

 

-11- 

notice from Participant of its exercise of such right, either (i) immediately repurchase Participant’s ownership interest in such
Defective Mortgage Loan by remitting to Participant the allocable amount paid by Participant for such Defective Mortgage Loan plus interest at the Pass-Through Rate on the principal amount thereof from the date of Participant’s purchase of such
Participation Certificate to the date of such repurchase, or (ii) deliver to Custodian a Mortgage Loan eligible to back such Security in exchange for such Defective Mortgage Loan, which newly delivered Mortgage Loan shall be in all respects
acceptable to Participant in Participant’s sole discretion, and such newly delivered Mortgage Loan will thereupon become one of the Mortgage Loans evidenced by the Participation Certificate. If the aggregate principal balance of any Mortgage
Loans that are accepted by Participant pursuant to clause (ii) of the immediately preceding sentence is less than the aggregate principal balance of any Defective Mortgage Loan that is being replaced by such Mortgage Loan, Seller shall remit with
such Mortgage Loan to Participant an amount equal to the difference between the aggregate principal balance of the new Mortgage Loan accepted by Participant and the aggregate principal balance of the Defective Mortgage Loan being replaced thereby.

 
(2) If Seller fails to comply with its
obligations in the manner described in Section 3(c)(1), or Seller is in breach of Section 8(a)(viii) or 8(b)(vii), not later than the third calendar day after receipt by Seller of notice from Participant (or if such day is not a business day, the
next business day thereafter), Seller’s rights and obligations to service the Mortgage Loans evidenced by such Participation Certificate, as provided in this Agreement, shall terminate. If an Act of Insolvency occurs at any time, Seller’s
rights and obligations to service the Mortgage Loans, as provided in this Agreement, shall terminate immediately, without any notice or action by Participant. Upon any such termination, Participant is hereby authorized and empowered as the exclusive
agent for Seller to sell and transfer such rights to service the Mortgage Loans for such price and on such terms and conditions as Participant shall reasonably determine. Seller shall not otherwise attempt to sell or transfer such rights to service
without the prior consent of Participant. Seller shall perform all acts and take all action so that the Mortgage Loans and all files and documents relating to such Mortgage Loans held by Seller, together with all escrow amounts relating to such
Mortgage Loans, are delivered to Successor Servicer. To the extent that the approval of the Applicable Agency is required for any such sale or transfer, Seller shall fully cooperate with Participant to obtain such approval. Upon exercise by
Participant of its remedies under this Section 3(c)(2), Seller hereby authorizes Participant to receive all amounts paid by any purchaser of such rights to service the Mortgage Loans and to remit such amounts to Seller subject to Participant’s
rights of set-off under this Agreement. Upon exercise by Participant of its remedies under this Section 3(c)(2), Participant’s obligation to pay and Seller’s right to receive any portion of the Performance Fee relating to such Mortgage
Loans shall automatically be canceled and become null and void, provided that such cancellation shall in no way relieve Seller or otherwise affect the obligation of Seller to indemnify and hold Participant harmless as specified in Section 3(e).

 
(d) Mortgage Loans required to be delivered to
Successor Servicer by Section 3(c)(2) shall be delivered free of any servicing rights in favor of Seller and free of any title, interest, lien, encumbrance or claim of any kind of Seller. Seller shall deliver or cause to be delivered all files and
documents relating to such Mortgage Loans held by Seller to Successor Servicer. Seller shall promptly take such actions and furnish to Participant such documents that 
 

-12- 

Participant deems necessary or appropriate to enable Participant to obtain a Security backed by such Mortgage Loans or to enforce such
Mortgage Loans, as appropriate. 
 
(e) Seller
agrees to indemnify and hold Participant and its assigns harmless from and against all Losses (including, without limitation, Losses incurred by Participant on account of fees paid by Participant to the Applicable Agency to cause the Securities to
be issued or any Losses in connection with any indemnification by Participant of the Applicable Agency) resulting from or relating to any breach or failure to perform by Seller of any representation, warranty. covenant, term or condition made or to
be performed by Seller under this Agreement. 
 
(f)
No exercise by Participant of its rights under this Section 3 shall relieve Seller of responsibility or liability for any breach of this Agreement. 
 
(g) Seller hereby grants Participant a right of set-off against the payment of any amounts that may be due and payable to Participant from
Seller, such right to be upon any and all monies or other property of Seller held or received by Participant or due and owing from Participant to Seller. 
 
Section 4. Servicing of the Mortgage Loans. 
 
(a) It is expressly acknowledged that the Servicing Rights relating to the Mortgage Loans evidenced by each
Participation Certificate purchased by Participant hereunder have been sold, assigned, and transferred by Seller to Participant along with the ownership interest in such Mortgage Loans as evidenced by a Participation Certificate. Seller shall
service and administer the Mortgage Loans evidenced by a Participation Certificate on behalf of Participant on an interim basis in accordance with accepted and prudent mortgage loan servicing standards and procedures generally accepted in the
mortgage banking industry for the same type of mortgage loans as the Mortgage Loans and in a manner at least equal in quality to the servicing the Seller provides for mortgage loans which it owns and in accordance with the requirements of the GNMA
Program, FNMA Program or FHLMC Program, as the case may be, provided that Seller shall at all times comply with applicable law, FHA regulations and VA regulations and the requirements of any private mortgage insurer so that the FHA insurance, VA
guarantee or any other applicable insurance or guarantee in respect of any Mortgage Loan is not voided or reduced. Seller shall at all times maintain accurate and complete records of its servicing of the Mortgage Loans, and Participant may, at any
time during Seller’s business hours on reasonable notice, examine and make copies of such records. On the second (2nd) day of each calendar month, or at any other time upon Participant’s request, Seller shall deliver to Participant reports regarding the status of each Mortgage Loan in accordance with Section 9(g) and Section 9(h), which shall
include, but shall not be limited to, a description of those Mortgage Loans in default for more than thirty (30) days, and any circumstances that could materially adversely affect any of such Mortgage Loans, Participant’s ownership of any of
such Mortgage Loans or the collateral securing any of such Mortgage Loans. Seller shall deliver such a report to Participant every thirty (30) days until (i) Delivery of the related Security to Participant or (ii) the exercise by Participant of any
remedial election pursuant to Section 3. The Seller agrees and acknowledges that Participant may, at any time, terminate the servicing of the Mortgage Loans by Seller and transfer servicing to another Person on such date as Participant may determine
in its sole discretion. In the event that anything in this Agreement is interpreted as constituting one 

 

-13- 

or more interim servicing contracts, each such servicing contract shall terminate automatically upon the earlier of (i) Delivery of the
related Security to Participant or (ii) Participant’s notice to Seller directing Seller to transfer servicing (provided, Seller’s obligations as set forth herein to cooperate in the transfer of such servicing shall not terminate until such
servicing has actually been transferred in full); 
 
(b) Within two (2) Business Days of notice from Participant or with respect to each Participation Certificate, on the Settlement Date: 
 
(i) Seller shall establish and maintain a separate custodial account (the “Custodial Account”) entitled
“Crescent Mortgage Services, Inc., in trust for UBS Real Estate Securities Inc. and its assignees under the Amended and Restated Mortgage Loan Participation Agreement dated January 31, 2003 and shall promptly deposit into such Custodial
Account, in the form received with any necessary endorsements, all collections received in respect of each Mortgage Loan evidenced by a Participation Certificate that are payable to Participant as the owner of such Participation Certificate; and

 
(ii) at the Participant’s
sole option, upon written notice from the Participant, the Seller shall transfer servicing of the Mortgage Loans to a Successor Servicer designated by the Participant. 
 
(c) Amounts deposited in the Custodial Account with respect to any Mortgage Loan shall be held in trust for
Participant as the owner of the Mortgage Loans and shall be released only as follows: 
 
(i) Except as otherwise provided in Section 4(c)(ii), upon Delivery of the Security backed by such Mortgage Loans to
Participant and either (i) receipt by Participant or its designee of the purchase price for the Security from the Takeout Investor or (ii) if earlier, on the date required by the GNMA Guide, FNMA Guide or FHLMC Guide, as the case may be, amounts
deposited in the Custodial Account shall be released in accordance with Section 3(a)(3). Notwithstanding the foregoing, all amounts deposited in the Custodial Account shall be paid to Seller upon the Delivery of the related Security to Participant
if, and to the extent that, the amounts due and payable to Participant hereunder have been set-off against the Purchase Price for the related Participation Certificate or the Performance Fee relating to the Mortgage Loans underlying such
Participation Certificate. The amounts paid to Seller (if any) pursuant to this Section 4(c)(i) shall constitute Seller’s sole compensation for servicing the Mortgage Loans as provided in this Section 4. 
 
(ii) If a Successor Servicer takes delivery
of such Mortgage Loans either under the circumstances set forth in clause (b)(ii) above, or otherwise, all amounts deposited in the Custodial Account shall be paid to Participant promptly upon such delivery. 
 
(iii) During the period that Seller acts as
servicer, all amounts deposited in the Custodial Account shall be released only in accordance with Participant’s written instructions.

Section 5.
Takeout Commitments. Seller hereby assigns to Participant, free of any security interest, lien, claim or encumbrance of any kind, Seller’s rights under each Takeout Commitment to deliver the Security specified therein to the related
Takeout Investor and to receive the purchase price therefor from such Takeout Investor. Subject to Participant’s rights under Section 3, Participant agrees that it will satisfy the Takeout Commitment on the Settlement Date specified therein.
Seller understands that, as a result of this Section 5 and each Trade Assignment, Participant will succeed to the rights and obligations of Seller with respect to each Takeout Commitment subject to a Trade Assignment, and that in satisfying each
such Takeout Commitment, Participant will stand in the shoes of Seller and, consequently, will be acting as a non-dealer in exercising its rights and fulfilling its obligations assigned pursuant to this Section 5 and each Trade Assignment. Each
Trade Assignment delivered by Seller to Participant pursuant to Section 2 shall be delivered by Seller in a timely manner sufficient to enable Participant to facilitate the settlement of the related trade on the trade date in accordance with Chapter
8 of the Bond Market Association’s Uniform Practices for the Clearance and Settlement of Mortgage-Backed Securities and other Related Securities, as amended from time to time. 
 
Section 6. Transfers of Participation Certificates and Securities by Participant. Participant may, in
its sole discretion and without the consent of Seller, assign all of its right, title and interest or grant a security interest in any Participation Certificate, any Mortgage Note, Mortgage and any assignment of Mortgages (an “Assignment of
Mortgage”), each Security in respect thereof of which Delivery is made to Participant and all rights of Participant under this Agreement (including, but not limited to, the Custodial Account) in respect of such Participation Certificate,
Mortgage Note, Mortgage, Assignment of Mortgage and such Security, to any person (an “Assignee”), subject only to an obligation on the part of the Assignee to deliver each such Security to a Takeout Investor pursuant to Section 5 or
to Participant to permit Participant or its designee to make delivery thereof to a Takeout Investor pursuant to Section 5. Assignment by Participant of a Participation Certificate as provided in this Section 6 will not release Participant from its
obligations otherwise under this Agreement. 
 
Without limitation of the foregoing, an assignment of the Participation Certificate to an Assignee, as described in this Section 6, shall be effective upon delivery of the Participation Certificate to the Assignee or its designee,
together with a duly executed Assignment in the Form of Exhibit E. 
 
Section 7. Record Title to Mortgage Loans; Intent of Parties; Security Interest. 
 
(a) From and after the issuance and delivery of the related Participation Certificate, and subject to the remedies of Participant in
Section 3, Seller shall remain the last named payee or endorsee of each Mortgage Note and the mortgagee or assignee of record of each Mortgage (except with respect to a MERS Designated Mortgage Loan) in trust for the benefit of Participant, for the
sole purpose of facilitating the servicing of such Mortgage Loan and the issuance of a Security backed by such Mortgage Loan. Where Seller has appointed FHLMC as Custodian, the parties hereto acknowledge that the Mortgage Notes acquired hereunder
have been deposited with FHLMC to facilitate the issuance of FHLMC Securities with respect thereto and that prior to such issuance FHLMC is holding such Mortgage Notes as Custodian for Participant. 
 

-15- 

 
(b) Seller
shall maintain a complete set of books and records for each Mortgage Loan which shall be clearly marked to reflect the ownership interest in each Mortgage Loan of the holder of the related Participation Certificate and with respect to each MERS
Designated Mortgage Loan, Seller shall designate the Participant as the Investor and Interim Funder on the MERS®
System. 
 
(c) Participant and Seller confirm that
the transactions contemplated herein are intended to be sales of the Mortgage Loans by Seller to Participant rather than borrowings secured by the Mortgage Loans. In the event, for any reason, any transaction is construed by any court or regulatory
authority as a borrowing rather than as a sale, the Seller and Participant intend that Participant or its Assignee, as the case may be, shall have a perfected first priority security interest in the Participation Certificates, any Custodial
Accounts, the Mortgage Loans subject to each Participation Certificate (including all servicing rights related thereto), all documents evidencing the Mortgage Loans, the Securities to be issued as contemplated hereunder and all proceeds thereof, the
Takeout Commitments and the proceeds of any and all of the foregoing (collectively, the “Collateral”), free and clear of adverse claims. In such case, Seller shall be deemed to have hereby granted to Participant or its Assignee, as
the case may be, a first priority security interest in and lien upon the Collateral, free and clear of adverse claims. In such event, this Agreement shall constitute a security agreement, the Custodian shall be deemed to be an independent custodian
for purposes of perfection of the security interest granted to Participant, and Participant or each such Assignee shall have all of the rights of a secured party under applicable law.

[EXHIBIT G] 
 
[FORM OF OPINION] 
 
UBS Warburg Real Estate Securities 
[Address] 
 
Dear Sirs and Mesdames:

 
You have requested [my] [our] opinion as counsel to Crescent
Mortgage Services, Inc., a corporation organized and existing under the laws of Georgia (the “Seller”), with respect to certain matters in connection with that certain Amended and Restated Mortgage Loan Participation Agreement
governing purchases and sales of certain Participation Certificates evidencing a 100% undivided ownership in certain Mortgage Loans, dated January 31, 2003 (the “Participation Agreement”), by and between Seller and UBS Warburg Real
Estate Securities (the “Participant”). The Participation Agreement and the Custodial Agreement, dated as of January 31, 2003 by and among Seller, the Participant and the Custodian (the “Custodial Agreement,) are
hereinafter collectively referred to as the “Governing Agreements.” Capitalized terms not otherwise defined herein have the meanings set forth in the Participation Agreement. 
 
[We] [I] have examined the following documents: 
 

	 	1.	 	the Participation Agreement; 

 

	 	2.	 	the Custodial Agreement; 

 

	 	3.	 	an unfiled copy of the financing statements listed on Schedule 1 (the “Financing Statement”) naming the Seller as Debtor and the Participant
as Secured Party and describing the Collateral (as defined in the Participation Agreement) as to which security interests may be perfected by filing under the Uniform Commercial Code of the State listed on Schedule 1 (the “Filing
Collateral”), which I understand will be filed in the filing office listed on Schedule 1 (the “Filing Offices”); 

 

	 	4.	 	the reports listed on Schedule 2 as to UCC financing statements naming the Seller as Debtor and on file in the Filing Office [and, if different, the filing
office of the jurisdiction in which Seller’s chief executive office is located] (collectively, the “UCC Search Report”); 

 

	 	5.	 	such other documents, records and papers as we have deemed necessary and relevant as a basis for this opinion. 

 
To the extent [we] [I] have deemed necessary and proper, [we]
[I] have relied upon the representations and warranties of the Seller contained in the Participation Agreement. [We] [I] have assumed the authenticity of all documents submitted to [me] [us] as originals, the genuineness of all signatures, the legal
capacity of natural persons and the conformity to the originals of all documents. 
 

G-1 

Based upon the foregoing, it is [our] [my] opinion that: 
 
1. The Seller is a corporation duly organized, validly
existing and in good standing under the laws of the State of Georgia and is qualified to transact business in, and is in good standing under, the laws of the State of
[                    ]. 
 
2. The execution, delivery and performance by the Seller of the Governing Agreements to which it is a party, and the sales by the Seller
of the Participation Certificates under the Participation Agreement have been duly authorized by all necessary corporate action on the part of the Seller. Each of the Governing Agreements have been executed and delivered by the Seller and are legal,
valid and binding agreements enforceable in accordance with their respective terms against the Seller, subject to bankruptcy laws and other similar laws of general application affecting rights of creditors and subject to the application of the rules
of equity, including those respecting the availability of specific performance, none of which will materially interfere with the realization of the benefits provided thereunder or with the Participant’s purchase of the Participation
Certificates or the Delivery of Securities therefor and/or security interest in the Collateral. The Seller has been duly authorized to allow any of its officers to execute any and all documents by original signature in order to complete the
transactions contemplated by the Participation Agreement and the Custodial Agreement. 
 
3. No consent, approval, authorization or order of, and no filing or registration with, any court or governmental agency or regulatory body is required on the part of the Seller for the execution,
delivery or performance by the Seller of the Governing Agreements to which it is a party or for the sales by the Seller under the Participation Agreement of the Participation Certificates to the Participant and/or granting of a security interest to
the Participant in the Collateral, pursuant to the Participation Agreement. 
 
4. The execution, delivery and performance by the Seller of, and the consummation of the transactions contemplated by the Governing Agreements to which it is a party do not and will not (a) violate any
provision of the Seller’s charter or by-laws, (b) violate any applicable law, rule or regulation, (c) violate any order, writ, injunction or decree of any court or governmental authority or agency or any arbitral award applicable to the Seller
of which [I] [we] have knowledge (after due inquiry) or (d) result in a breach of, constitute a default under, require any consent under, or result in the acceleration or required prepayment of any indebtedness pursuant to the terms of, any
agreement or instrument of which I have knowledge (after due inquiry) to which the Seller is a party or by which it is bound or to which it is subject, or result in the creation or imposition of any Lien upon any property of the Seller pursuant to
the terms of any such agreement or instrument. 
 
5. There is no action, suit, proceeding or investigation pending or, to the best of [our] [my] knowledge, threatened against the Seller which, in [our] [my] judgment, either in any one instance or in the aggregate, would be
reasonably likely to result in any material adverse change in the properties, business or financial condition, or prospects of the Seller or in any material impairment of the right or ability of the Seller to carry on its business substantially as
now conducted or in any material liability on the part of the Seller or which would draw into question the validity of the Governing Agreements to which it is a party or the Mortgage Loans or of any action taken or to be taken in connection with the
transactions contemplated thereby, or 

 

G-2 

which would be reasonably likely to impair materially the ability of the Seller to perform under the terms of the Governing Agreements to
which it is a party or the Mortgage Loans. 
 
6.
The Mortgages have been duly assigned and the Mortgage Notes have been duly endorsed as provided in the Custodial Agreement. The Assignments of Mortgage are in recordable form, except for the insertion of the name of the assignee, and upon the name
of the assignee being inserted, are acceptable for recording under the laws of the state where each related Mortgaged Property is located. The endorsement of the Mortgage Notes, the delivery to the Custodian of the Assignments of Mortgage, and the
delivery of the original endorsed Mortgage Notes to the Custodian are sufficient to permit the Purchaser to avail itself of all protection available under applicable law against the claims of any present or future creditors of the Seller, and are
sufficient to prevent any other sale, transfer, assignment, pledge or hypothecation of the Mortgages and the Mortgage Notes by the Seller from being enforceable. 
 
7. The Participation Agreement is effective to create, in favor of the Participant, a valid security interest
under the Uniform Commercial Code in all of the right, title and interest of the Seller in, to and under the Collateral as collateral security for the payment of the Seller’s obligations under the Participation Agreement. 
 
8. (a) Upon the filing of financing statements on Form UCC-1
naming the Participant as “Secured Party” and the Seller as “Debtor”, and describing the Collateral, in the Filing Office, the security interest referred to in Section 6 above will constitute fully perfected security interests
under the Uniform Commercial Code in all right, title and interest of the Seller in, to and under such Collateral, which can be perfected by filing under the Uniform Commercial Code. 
 
(b) The UCC Search Report sets forth the proper filing offices and the proper debtors
necessary to identify those Persons who have on file in the jurisdictions listed on Schedule 1 financing statements covering the Collateral as of the dates and times specified on Schedule 2. The UCC Search Report identifies no Person
who has filed in any Filing Office a financing statement describing the Collateral prior to the effective dates of the UCC Search Report. 
 
9. The Seller is not an “investment company”, or a company “controlled” by an “investment company,” within
the meaning of the Investment Company Act of 1940, as amended. 
 
Very truly yours,

the Custodian, the Custodian, subject to the provisions of paragraphs (b) and (c) of this Section, shall act solely in the capacity of custodian for, and bailee of, the Participant. The Custodian shall hold all documents constituting the Mortgage
File received by it for the exclusive use and benefit of the Participant, and shall make disposition thereof only in accordance with the written instructions furnished by the Participant. The Custodian shall segregate and maintain continuous custody
of all documents constituting the Mortgage File received by it in secure and fire-resistant facilities in accordance with customary standards for such custody and shall mark the file folders therefor to indicate that the Mortgage File is being held
for the Participant. Notwithstanding anything in this Section 3 to the contrary, upon delivery of a Security to the Participant or its designee, the Custodian shall automatically cease to hold the related Mortgage File on behalf of the Participant,
and this Agreement shall thereupon cease to be of any effect with respect thereto. 
 
(b) With respect to each Participation Certificate and/or each related Mortgage Note, Assignment of Mortgage and related Security, the Participant shall, upon assigning, pledging or granting a security
interest therein to an Assignee, notify the Custodian and such Assignee in writing that it has assigned, pledged or granted a security interest in each Participation Certificate and/or each related Mortgage Note, Assignment of Mortgage and related
Security to such Assignee. Subject to any limitations in any agreement between such Assignee and the Participant, such Assignee, upon notice, as provided in Section 17, may (i) require the Custodian to act with respect to the related Mortgage File
solely in the capacity of custodian for, and bailee of, such Assignee, (ii) require the Custodian to hold such Mortgage File for the exclusive use and benefit of such Assignee, (iii) assume the rights of Participant under this Agreement to furnish
written instructions to the Custodian as to the disposition of such Mortgage File and such rights shall be exercisable solely by such Assignee, (iv) require the Custodian to give such Assignee written acknowledgement to the effect set forth in (i),
(ii) and  (iii), and (v) take all such actions under the Electronic Tracking Agreement which are necessary to effectuate any of the foregoing. The failure of the Custodian to give the written acknowledgement referred 

 

-9- 

to in (iv) above shall not affect the validity of such assignment, pledge or grant of a security interest. The effects of the
Participant’s notice to the Custodian set forth in (i) to (iii) above shall continue until the Custodian is otherwise notified in writing by such Assignee, except that upon the delivery of the Security to the Participant or its designee, the
Custodian shall automatically cease to hold the Mortgage File on behalf of the Assignee, and this Agreement shall thereupon cease to be of any effect with respect thereto. Mortgage Notes and Assignments of Mortgages as to which the Participant has
assigned, pledged or granted a security interest to an Assignee are sometimes referred to in this Agreement as “Assigned Mortgage Loans.” 
 
(c) The Seller and the Participant acknowledge that the Warehouse Lender, if any, identified from time to time in each Exhibit  B-1
Letter to be received by the Custodian pursuant to Section 2(a), is a Warehouse Lender for the Seller. The Seller and the Participant acknowledge that, in accordance with the terms of each Exhibit B-1 Letter to be received by the Custodian pursuant
to Section 2(a) (except when the Warehouse Lender is the Participant), pursuant to which each such Warehouse Lender conditionally releases its security interest in Mortgage Loans referred to in the related Exhibit B-1 Letter, such release shall not
be effective until the funds referred to in such Exhibit B-1 Letter (a “Warehouse Payment”) are received in accordance with the Wire Instructions. Until receipt of a Warehouse Payment, the interest of the related Warehouse Lender in
such Mortgage Loans shall continue and remain in full force and effect, and the Participant shall have no interest in the Mortgage Loans which is not subordinate to the interest of each Warehouse Lender in such Mortgage Loans. The Seller and the
Participant acknowledge and agree to the foregoing arrangements. 
 
(d) In order to enable the Custodian to make the Certification described in Section 4(a), Participant shall, promptly after the execution of this Agreement, deliver to Custodian a limited power of attorney, in the form of Exhibit D
(the “Limited Power”), authorizing the Custodian, as attorney-in-fact of the Participant, upon receipt of Exhibit F letter, if applicable (i) to complete a new form HUD 11711A (Release of Security Interest), Fannie Mae Form 2004
(Security Release Certification), FHLMC Form 939 (Security Settlement Information and Delivery Authorization) or FHLMC Form 996 (Warehouse Lender Release of Security Interest), as applicable, naming the Participant as the “warehouse
lender” on each such form with respect to the applicable Mortgage Loans;  (ii) to substitute such completed forms for the corresponding forms, if any, previously delivered to the Custodian by the Seller, naming a person other than the
Participant as “warehouse lender;” and (iii) to include such completed substituted forms among the documents to be delivered by the Custodian pursuant to Section 4(a)(ii). 
 
Section 4. Certification of Receipt by Custodian. (a) Prior to authenticating a Participation
Certificate, the Custodian shall ascertain that all documents required to be delivered to it pursuant to Section 2 in respect of each Mortgage Loan Schedule are in its possession and shall certify (the “Certification”) to
Participant that: 
 

	 	(i)	 	 As to each Mortgage Loan listed in such Mortgage Loan Schedule, (A) all documents required to be delivered to it pursuant to Section 2 are in its possession, (B)
such documents have been reviewed by it and appear regular on their face and relate to such Mortgage Loan, (C) based only on its examination of the foregoing documents, the information set forth in 

 

-10- 

	 	 
the Mortgage Loan Schedule respecting such Mortgage Loan is correct, (D) such Participation Certificate is the only outstanding Participation
Certificate authenticated by it related to such mortgage pool (E) each Mortgage Note appears on its face to have been endorsed as provided in Section 2 and (F) each such Mortgage Loan is listed on a schedule attached to an Exhibit B-1 Letter or
Exhibit B-2 Letter, as the case may be. 

 

	 	(ii)	 	As to such Mortgage Loan Schedule, (A) the Applicable Agency Documents were received from the Seller and have been reviewed by it, have been completed, appear
regular on their face and relate to such Mortgage Loan Schedule, (B) either (x) such documents have been transmitted by the Custodian by overnight courier to GNMA, FNMA or FHLMC, as applicable or (y) upon receipt by the Custodian of the applicable
Exhibit F letter, the Applicable Agency Documents will be transmitted by the Custodian on the same day as such receipt, by overnight courier, to GNMA, FNMA or FHLMC, as applicable, and (C) with respect to the written instructions for delivery of the
Securities to be issued with respect to such Mortgage Loans as set forth in the copies, delivered or to be delivered in completed form to GNMA, FNMA or FHLMC, as applicable, of (x) form HUD 11705 (Schedule of Subscribers) with respect to the GNMA
Program, (y) Fannie Mae Form 2014 (Delivery Schedule) with respect to the FNMA Program or (z) FHLMC Form 939 (Settlement and Information Multiple Registration Form) with respect to the FHLMC Program, such instructions for delivery are identical to
the instructions for delivery of such Securities set forth in the copies of such forms delivered to the Participant. 

 
As to each MERS Designated Mortgage Loan, the Custodian shall verify the related “MERS Identification Number” listed on the
related Mortgage Note, the Mortgage Loan Schedule and the MERS Report. 
 
Upon receipt of all the documents required to be delivered to it pursuant to Section 2, Custodian shall execute the Participation Certificate and deliver to Participant by overnight courier the fully completed Participation
Certificate and Mortgage Loan Schedule attached thereto, a copy of each Exhibit B-1 Letter or Exhibit B-2 Letter and a fully completed copy of (i) Form HUD 11705 (Schedule of Subscribers), (ii) Fannie Mae Form 2014 (Delivery Schedule) or (iii) a
copy of FHLMC Form 381 (Contract Delivery Summary) and a copy of FHLMC Form 939 (Settlement and Information Multiple Registration Form), as the case may be, designating the Participant as the party authorized to receive the Securities, executed by
the Seller and relating to the Securities to be backed by the Mortgage Loans. The execution by the Custodian of each Participation Certificate shall constitute an express representation and warranty by the Custodian to the Participant that the
Custodian has performed the Certification with respect to the Participation Certificate, the Mortgage Loans evidenced thereby and the documents referenced in Section 2 received from the Seller in connection therewith. 
 

	 	(iii)	 	 So long as the Custodian holds a Mortgage File on behalf of the Participant, in the event the Custodian discovers any defect with respect to 

 

-11- 

	 	 
such Mortgage File or the related forms, the Custodian shall give prompt oral notice of such defect to the Seller and the Participant,
followed by a written specification thereof. 

 
Section 5. Custodian’s Fees and Expenses; Successor Custodian. (a) It is understood that the Custodian will charge such fees for its services under this Agreement as are set forth in a separate agreement between the
Custodian and the Seller, the payment of which, together with the Custodian’s expenses in connection herewith, shall be solely the obligation of the Seller. The Custodian has no lien on, and shall not attempt to place a lien on, any of the
Mortgage Loans or proceeds thereof to secure the payment of its fees. 
 
(b) The Custodian or any successor Custodian may resign at any time by giving 30 days’ written notice to the Seller and the Participant. Such resignation shall take effect upon (i) the appointment of a successor
Custodian by the Seller, which successor Custodian shall be a bank or trust company acceptable to the Participant, each Assignee and to GNMA, FNMA or FHLMC, as applicable, and (ii) delivery of all the Mortgage Files to the successor Custodian.

 
(c) The Seller may (and shall, upon the written
request of the Participant) at any time remove and discharge the Custodian or any successor Custodian thereafter appointed from the performance of its duties under this Agreement by written notice from the Seller to the Custodian or the successor
Custodian, with copies to the Participant. Such removal shall take effect upon (i) the appointment of a successor Custodian by the Seller, which Custodian shall be a bank or trust company acceptable to the Participant, each Assignee and to GNMA,
FNMA or FHLMC, as applicable, and (ii) delivery of all the Mortgage Files to the successor Custodian. 
 
(d) In the event of any such resignation or removal, the Custodian shall, at the expense of the Seller, promptly transfer to the successor
Custodian within thirty (30) days all Mortgage Files being administered under this Agreement and the successor Custodian shall hold such Mortgage Files in accordance with this Agreement. In the event of any such appointment, the Seller shall be
responsible for the fees of the successor Custodian. 
 
(e) The Seller agrees to indemnify, reimburse and hold harmless the Custodian, its directors, officers, employees and agents from and against any and all liability, loss and expense, including counsel fees and disbursements arising
from or connected with the Custodian’s execution and performance of this Agreement including but not limited to claims of third parties, including the Participant, except in the case of loss, liability or expenses resulting from the gross
negligence or willful misconduct on the part of the Custodian. The foregoing indemnification shall survive the termination or assignment of this Agreement. 
 
(f) The standard of care to be exercised by Custodian in the performance of its duties under this Agreement shall be to exercise the same
degree of care as Custodian exercises when it holds mortgage loan documents as security for its own loans, if any, or warehouse loans. Custodian is an agent, bailee and custodian only and is not intended to be, nor shall it be construed to be
(except only as agent, bailee and custodian), a representative, trustee or fiduciary of or for either Seller, the Agency, Participant or Assignee. The Custodian shall not be bound in any way by any agreement or contract other than this Agreement and
the exhibits and schedules hereto and any other agreement to which it is a party. The Custodian shall not be 

 

-12- 

required to ascertain or inquire as to the performance or observance of any of the conditions or agreements to be performed or observed by
any other party, except as specifically provided in this Agreement and the exhibits and schedules hereto. The Custodian disclaims any responsibility for the validity or accuracy of the recitals to this Agreement and any representations and
warranties contained herein, unless specifically identified as recitals, representations or warranties of the Custodian. 
 

	 	(i)	 	Throughout the term of this Agreement, other than as specifically set forth in this Agreement, the Custodian shall have no responsibility ascertaining the value,
collectibility, insurability, enforceability, effectiveness or suitability of any collateral, the title of any party therein, the validity or adequacy of the security afforded thereby, or the validity of this Agreement (except as to Custodian’s
authority to enter into this Agreement and to perform its obligations hereunder). 

 

	 	(ii)	 	No provision of this Agreement shall require the Custodian to expend or risk 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 and powers, if, in its sole judgment, it shall believe that repayment of such funds or adequate indemnity against such risk or liability is not assured  to it. 

 

	 	(iii)	 	The Custodian is not responsible for preparing or filing any reports or returns relating to federal, state or local income taxes with respect to this Agreement,
other than for the Custodian’s compensation or for reimbursement of expenses.

Section 6. Default. If the Seller fails to fulfill any of its obligations under the
Participation Agreement, the Electronic Tracking Agreement or hereunder or in connection with the exercise by Participant of any remedy pursuant to Section 3(c) of the Participation Agreement then, subject to the provisions of Section 3(b), the
Participant may, by written notice to the Custodian, (a) require the Custodian to complete the endorsements on the Mortgage Notes held by the Custodian and/or (b) require the Custodian to deliver to Participant or Successor Servicer the Mortgage
Files to which the failure relates and (c) take such actions under the Electronic Tracking Agreement on behalf of the Purchaser as are necessary to effectuate the foregoing. 
 
Section 7. Access to Documents. Upon reasonable prior written notice to the Custodian, the Participant
(and with respect to Assigned Mortgage Loans, each Assignee) and their agents, accountants, attorneys and auditors will be permitted during normal business hours to examine and copy the Mortgage Files, documents, records and other papers in
possession of or under the control of the Custodian relating to any or all of the Mortgage Loans in which the Participant has an interest. Upon the written request of the Participant (and with respect to Assigned Mortgage Loans, each Assignee) and
at the cost and expense of the Participant, the Custodian shall provide the Participant (and with respect to Assigned Mortgage Loans, each Assignee) with copies of the Mortgage Notes, Mortgages, Assignment of Mortgages and other documents relating
to any of the Mortgage Loans in which the Participant (and with respect to Assigned Mortgage Loans, each Assignee) has an interest. 
 
Section 8. Assignment by Participant. The Participant may assign, pledge or grant a security interest in any or all of its rights
under this Agreement and the Electronic Tracking Agreement to one or more Assignees in connection with the assignment, pledge or grant of a security interest in a Participation Certificate, and/or related Mortgage Notes, Assignments of Mortgages and
related Security. In addition to the notice required by Section 3(b), the Participant shall give written notice thereof to the Seller and the Custodian. The failure of the Participant to give such notice shall not affect the validity of any such
assignment, pledge or grant of a security interest. If the Participant does, however, fail to give such notice to the Seller and the Custodian, then the Assignee may give such notice to the Seller and the Custodian. Upon receipt of such notice by
the Seller and the Custodian, copies of all communications required to be sent hereunder to the Participant shall be sent to both the Participant and each Assignee (at its address set forth in such notice of assignment). Subject to any limitations
in any agreement between such Assignee and the Participant, such Assignee may, upon notice as provided in Section 16 hereof, directly enforce and exercise such rights under this Agreement that have been assigned or pledged to it or are the subject
of a security interest granted to it and, until otherwise notified by such Assignee, the Participant shall no longer have any of such rights. 
 

-14- 

Section 9. Insurance. The Custodian shall, at its own expense, maintain at all
times during the existence of this Agreement (a) fidelity insurance, (b) theft of documents insurance, (c) forgery insurance and (d) errors and omissions insurance. All such insurance shall be in amounts, with standard coverage and subject to
deductibles, all as is customary for insurance typically maintained by banks which act as custodians and be in such amounts and with insurance companies reasonably acceptable to the Participant. A certificate of the respective insurer as to each
such policy, with a copy of such policy attached, shall be furnished to the Participant, upon request, containing the insured’s statement or endorsement that such insurance shall not terminate prior to receipt by the Participant, by registered
mail, of 30 days’ notice thereof. 
 
Section
10. Representations, Warranties and Covenants of the Custodian. The Custodian hereby represents and warrants to, and covenants with, the Seller and the Participant that, as of the date hereof and at all times while Custodian is performing

each Mortgage Loan and to execute, deliver and perform, and to enter into and consummate all transactions contemplated by, this Agreement, has duly authorized the execution, delivery and performance of this Agreement and has duly executed and
delivered this Agreement, and this Agreement constitutes a legal, valid and binding obligation of the Custodian, enforceable against it in accordance with its terms. 
 
(c) Neither the execution and delivery by the Custodian of this Agreement, nor the consummation by the
Custodian of any of the transactions contemplated hereby, nor the fulfillment by the Custodian of the terms hereof, will conflict with, or violate, result in a material breach of or constitute a material default (with or without notice or lapse of
time, or both) under (i) any term or provision of the Certificate of Incorporation or By-laws of the Custodian or any governmental rule applicable to the Custodian or (ii) any term or provision of any indenture or other agreement or instrument, to
which the Custodian is a party or by which the Custodian or any material portion of its properties are bound. No governmental action is required by or with respect to the Custodian in connection with the execution and delivery of this Agreement by
the Custodian or the consummation by the Custodian of the transactions contemplated hereby.

-15- 

Section 11. Indemnification by Custodian. The Custodian agrees to indemnify and
hold the Seller and Participant, and their respective designees harmless against any and all liabilities, obligations, losses, damages, penalties, actions, judgements, suits, costs, or out-of-pocket expenses, including reasonable attorney’s
fees, that may be imposed on, incurred by, or asserted against it or them in any way relating to or arising out of the Custodian’s gross negligence or willful misconduct or any breach of the covenants, conditions, representations or warranties
contained herein. The foregoing indemnification shall survive any termination or assignment of this Agreement. 
 
Section 12. No Adverse Interests. By its acceptance of each Mortgage File, the Custodian covenants and warrants to the Participant
that the Custodian holds no adverse interests, by way of security or otherwise, in the related Mortgage Loan and the Custodian hereby waives and releases any such interest in such Mortgage Loan which it, acting as Custodian, has or which it may
thereafter acquire prior to the time of release of such Mortgage Loan from the terms of this Agreement.

the extent permitted by applicable law, this Agreement shall be filed and/or recorded by the Seller at its expense in all appropriate public offices on direction by the Participant accompanied by an opinion of counsel to the Participant (who may

Section 15. Execution in Counterparts. This Agreement may be executed in any number of counterparts,
each of which shall be deemed an original, but all of which shall constitute one and the same instrument. 
 
Section 16. Agreement for Exclusive Benefit of Parties; Assignment. This Agreement is for the exclusive benefit of the parties
hereto and their respective successors and permitted assigns hereunder and shall not be deemed to give any legal or equitable right, remedy or claim to any other person whatsoever. This Agreement shall bind the parties hereto and their respective
successors, but, except as provided in Section 9, shall not be assigned or pledged by any party without the prior written consent of the other parties. Written notice from an Assignee to the Custodian (with a copy to the Participant) that the
Participant has defaulted in any material respect under any funding or loan agreement relating to the financing of the Participant’s purchase of Participation Certificates shall be conclusive for all purposes of this Agreement and after receipt
of such notice, the Custodian shall act in accordance with the written instructions of the Assignee with respect to the related Mortgage Files.
