MORTGAGE SECURITIES, LLC, as Depositor, OPTION ONE MORTGAGE CORPORATION, as Servicer, WELLS FARGO BANK, N.A., as Master Servicer, Securities Administrator and Custodian and HSBC BANK USA, NATIONAL ASSOCIATION, as Trustee. 
 PRELIMINARY STATEMENT: 
 The Depositor
intends to sell pass-through certificates to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest of the Trust Fund created hereunder. The Trust Fund will consist of a segregated pool
of assets comprised of the Mortgage Loans and certain other related assets subject to this Agreement. 
 REMIC I 
 As provided herein, the Trustee shall make an election to treat the segregated pool of assets consisting of the Mortgage Loans and certain other related
assets subject to this Agreement (but exclusive of the Reserve Fund, the Servicer Prepayment Charge Payment Amounts, the Swap Account and the Interest Rate Swap Agreement) as a real estate investment conduit (a “REMIC”) for federal income
tax purposes, and such segregated pool of assets will be designated as “REMIC I.” The Class R-I Interest will represent the sole class of “residual interests” in REMIC I for purposes of the REMIC Provisions. The following table
irrevocably sets forth the designation, the Uncertificated REMIC I Pass-Through Rate, the initial Uncertificated Principal Balance, and for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible
maturity date” for each of the REMIC I Regular Interests. None of the REMIC I Regular Interests will be certificated.

to such Mortgage Loan and (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to item (i) of the Mortgage Loan Schedule accurately reflects information set
forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Custodian is under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they
are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face. 
 Prior to the first anniversary date of this Agreement, the Custodian shall deliver to the Depositor, the Servicer and the Trustee a final certification
in the form annexed hereto as Exhibit F-2 evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon. 
  

 67 

 If in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the
certifications referred to above, the Custodian finds any document or documents constituting a part of a Mortgage File to be missing or defective in any material respect, at the conclusion of its review the Custodian shall so notify the Originator,
the Depositor, the Trustee and the Servicer. In addition, upon the discovery by the Originator, the Depositor, the Trustee or the Servicer (or upon receipt by the Trustee of written notification of such breach) of a breach of any of the
representations and warranties made by the Originator in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage
Loan, the party discovering such breach shall give prompt written notice to the other parties to this Agreement. 
 The Depositor and the
Trustee intend that the assignment and transfer herein contemplated constitute a sale of the Mortgage Loans, the related Mortgage Notes and the related documents, conveying good title thereto free and clear of any liens and encumbrances, from the
Depositor to the Trustee in trust for the benefit of the Certificateholders and that such property not be part of the Depositor’s estate or property of the Depositor in the event of any insolvency by the Depositor. In the event that such
conveyance is deemed to be, or to be made as security for, a loan, the parties intend that the Depositor shall be deemed to have granted and does hereby grant to the Trustee a first priority perfected security interest in all of the Depositor’s
right, title and interest in and to the Mortgage Loans, the related Mortgage Notes and the related documents, and that this Agreement shall constitute a security agreement under applicable law. 
 Section 2.03 Repurchase or Substitution of Mortgage Loans. 
 (a) Upon discovery or receipt of notice of any materially defective document in, or that a document is missing from, a Mortgage File or of a breach by the Originator or the Seller of any representation, warranty or
covenant under the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan that materially and adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Custodian or the Trustee shall promptly
notify the Seller, the Originator and the Servicer of such defect, missing document or breach and request that the Originator or the Seller deliver such missing document, cure such defect or breach within 60 days from the date the Originator was
notified of such missing document, defect or breach, and if the Originator or the Seller does not deliver such missing document or cure such defect or breach in all material respects during such period, the Trustee shall enforce the obligations of
the Originator or the Seller under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from the Trust Fund at the Purchase Price within 90 days after the date on which the Originator or the Seller was notified of such missing
document, defect or breach, if and to the extent that the Originator or the Seller is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall be remitted to the Servicer for deposit
in the Collection Account and the Trustee, upon receipt of written certification from the Servicer of such deposit, shall release or cause the Custodian to release to the Originator or cause the Custodian to release to the Seller the related
Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as the Originator or the 

  

 68 

 
Seller shall furnish to it and as shall be necessary to vest in the Originator or the Seller any Mortgage Loan released pursuant hereto, and the Trustee and
the Custodian shall not have any further responsibility with regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Originator or the Seller may
cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in
Section 2.03(b). It is understood and agreed that the obligation of the Originator or the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document
exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such omission, defect or breach available to the Trustee and the Certificateholders. 
 In addition, promptly upon the earlier of discovery by the Servicer or receipt of notice by the Servicer of the breach of the representation or covenant
of the Originator set forth in Section 6(www) of the Mortgage Loan Purchase Agreement which materially and adversely affects the interests of the Holders of the Class P Certificates in any Prepayment Charge, the Servicer shall promptly notify
the Originator and the Trustee of such breach. The Trustee shall enforce the obligations of the Originator under the Mortgage Loan Purchase Agreement to remedy such breach to the extent and in the manner set forth in the Mortgage Loan Purchase
Agreement. 
 (b) Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a)
must be effected prior to the date which is two years after the Closing Date. 
 As to any Deleted Mortgage Loan for which the Originator or
the Seller substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Originator or the Seller delivering to the Trustee or the Custodian on behalf of the Trustee, for such Qualified Substitute Mortgage
Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers’ Certificate
providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Shortfall Amount (as described below), if any, in connection with such substitution. The Custodian on behalf of the Trustee
shall acknowledge receipt of such Qualified Substitute Mortgage Loan or Loans and, within ten Business Days thereafter, review such documents as specified in Section 2.02 and deliver to the Depositor, the Trustee and the Servicer, with respect
to such Qualified Substitute Mortgage Loan or Loans, an initial certification in the form attached hereto as Exhibit F-1, with any applicable exceptions noted thereon. Within one year of the date of substitution, the Custodian on behalf of the
Trustee shall deliver to the Depositor, the Trustee and the Servicer a final certification pursuant to the this Agreement with respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly
Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of REMIC I and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will reflect the Monthly
Payment due on such Deleted Mortgage Loan on or before the Due Date in the month of substitution, and the Originator shall thereafter be entitled to retain all amounts subsequently 

  

 69 

 
received in respect of such Deleted Mortgage Loan. The Depositor shall give or cause to be given written notice to the Certificateholders that such
substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a
copy of such amended Mortgage Loan Schedule to the Trustee and the Servicer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this
Agreement and the Mortgage Loan Purchase Agreement including all applicable representations and warranties thereof included herein or in the Mortgage Loan Purchase Agreement. 
 For any month in which the Originator or the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans,
the Servicer will determine the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan,
the Scheduled Principal Balance thereof as of the date of substitution, together with one month’s interest on such Scheduled Principal Balance at the applicable Net Mortgage Rate, plus all outstanding P&I Advances and Servicing Advances
(including Nonrecoverable P&I Advances and Nonrecoverable Servicing Advances) related thereto. On the date of such substitution, the Originator or the Seller will deliver or cause to be delivered to the Servicer for deposit in the Collection
Account an amount equal to the Substitution Shortfall Amount, if any, and the Trustee or the Custodian on behalf of the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans, upon receipt of a request for release and
certification by the Servicer of such deposit, shall release to the Originator or the Seller the related Mortgage File or Files and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse,
representation or warranty, as the Originator or the Seller shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto. 
 In addition, the Originator or the Seller, as the case may be, shall obtain at its own expense and deliver to the Trustee an Opinion of Counsel to the
effect that such substitution will not cause (a) any federal tax to be imposed on any Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(1) of the Code or on
“contributions after the startup date” under Section 860G(d)(1) of the Code, or (b) any REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding. 
 (c) Upon discovery by the Depositor, the Seller, the Originator, the Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified
mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Originator shall repurchase or
substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made
by (i) the Originator if the affected Mortgage Loan’s status as a non-qualified mortgage is or results from a breach of any representation, warranty or covenant made by the Originator under the Mortgage Loan Purchase Agreement or
(ii) the Depositor, if the affected Mortgage Loan’s status as a non-qualified mortgage is a breach of no representation or warranty. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a).
The Trustee shall 

  

 70 

 
reconvey to the Originator the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage
Loan repurchased for breach of a representation or warranty. 
 (d) With respect to a breach of the representations made pursuant to
Section 6 of the Mortgage Loan Purchase Agreement that materially and adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Originator shall be required to take the actions set forth in this
Section 2.03. 
 (e) Within 90 days of the earlier of discovery by the Servicer or receipt of notice by the Servicer of the breach of
any representation, warranty or covenant of the Servicer set forth in Section 2.05 which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan or Prepayment Charge, the Servicer shall cure such breach in
all material respects.

 ARTICLE III 
 ADMINISTRATION AND
SERVICING 
 OF THE MORTGAGE LOANS; ACCOUNTS 
 Section 3.01 Servicer to Act as Servicer. 
 The Servicer shall service and administer the Mortgage
Loans on behalf of the Trust Fund and in the best interests of and for the benefit of the Certificateholders (as determined by the Servicer in its reasonable judgment) in accordance with the terms of this Agreement and the respective Mortgage Loans
and all applicable law and regulations and, to the extent consistent with such terms, in the same manner in which it services and administers similar mortgage loans for its own portfolio, giving due consideration to customary and usual standards of
practice of prudent mortgage lenders and loan servicers administering similar mortgage loans but without regard to: 
 (i) any
relationship that the Servicer’s or any Affiliate of the Servicer may have with the related Mortgagor; 
 (ii) the
ownership of any Certificate by the Servicer or any Affiliate of the Servicer; 
 (iii) the Servicer’s obligation to make
P&I Advances or Servicing Advances; or 
 (iv) the Servicer’s right to receive compensation for its services
hereunder. 
 To the extent consistent with the foregoing, the Servicer shall also seek to maximize the timely and complete recovery of
principal and interest on the Mortgage Notes related to the Mortgage Loans and shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing
similar Mortgage Loans and such waiver is related to a default or reasonably foreseeable default and would, in the reasonable judgment of the Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and
the related Mortgage Loan and, if such waiver is made in connection with a refinancing of the related Mortgage Loan, such refinancing is related to a default or a reasonably foreseeable default or (ii) such Prepayment Charge is unenforceable in
accordance with applicable law or the collection of such related Prepayment Charge would otherwise violate applicable law. 
 Subject only to
the above-described servicing standards (the “Accepted Servicing Practices”) and the terms of this Agreement and of the respective Mortgage Loans, the Servicer 

  

 77 

 
shall have full power and authority, to do or cause to be done any and all things in connection with such servicing and administration which it may deem
necessary or desirable. Without limiting the generality of the foregoing, the Servicer in its own name is hereby authorized and empowered by the Trustee when the Servicer believes it appropriate in its best judgment, to execute and deliver, on
behalf of the Trust Fund, the Certificateholders and the Trustee or any of them, and upon written notice to the Trustee, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge or subordination, and all
other comparable instruments, with respect to the Mortgage Loans and the Mortgaged Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert the ownership of such properties, and to hold or cause to
be held title to such properties, on behalf of the Trustee, for the benefit of the Trust Fund and the Certificateholders. The Servicer shall service and administer the Mortgage Loans in accordance with applicable state and federal law and shall
provide to the Mortgagors any reports required to be provided to them thereby. The Servicer shall also comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any standard hazard insurance policy.
Subject to Section 3.14, the Trustee shall execute, at the written request of the Servicer, and furnish to the Servicer any special or limited powers of attorney and other documents (in form reasonably acceptable to the Trustee) necessary or
appropriate to enable the Servicer to carry out its servicing and administrative duties hereunder and furnished to the Trustee by the Servicer, and the Trustee shall not be liable for the actions of the Servicer under such powers of attorney, or
such other documents furnished by the Trustee pursuant to this paragraph and shall be indemnified by the Servicer for any cost, liability or expense incurred by the Trustee in connection with the Servicer’s use or misuse of any such power of
attorney or other document furnished by the Trustee pursuant to this paragraph. 
 In accordance with Accepted Servicing Practices, the
Servicer shall make or cause to be made Servicing Advances as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which Servicing Advances shall be reimbursable in the first instance from related
collections from the Mortgagors pursuant to Section 3.07, and further as provided in Section 3.09; provided, however, the Servicer shall only make such Servicing Advance if the related Mortgagor has not made such payment and if the
failure to make such Servicing Advance would result in the loss of the related Mortgaged Property due to a tax sale or foreclosure as result of a tax lien. Any cost incurred by the Servicer in effecting the payment of taxes and assessments on a
Mortgaged Property shall not, for the purpose of calculating the Stated Principal Balance of such Mortgage Loan or distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit. 
 Notwithstanding anything in this Agreement to the contrary, the Servicer may not make any future
advances with respect to a Mortgage Loan and the Servicer shall not permit any modification with respect to any related Mortgage Loan that would change the Mortgage Rate, reduce or increase the principal balance (except for reductions resulting from
actual payments of principal) or change the final maturity date on such related Mortgage Loan (unless, as provided in Section 3.06, the related Mortgagor is in default with respect to the related Mortgage Loan or such default is, in the
judgment of the Servicer, reasonably foreseeable) or any modification, waiver or amendment of any term of any Mortgage Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or
final, temporary or 

  

 78 

 
proposed Treasury regulations promulgated thereunder) and (B) cause any REMIC created hereunder to fail to qualify as a REMIC under the Code or the
imposition of any tax on “prohibited transactions” or “contributions after the startup date” under the REMIC Provisions. 
 Section 3.02 Sub-Servicing Agreements Between the Servicer and Sub-Servicers. 
 The Servicer may arrange for the
subservicing of any Mortgage Loan by a Sub- Servicer pursuant to a Sub-Servicing Agreement; provided that such sub-servicing arrangement and the terms of the related Sub-Servicing Agreement must provide for the servicing of such Mortgage
Loans in a manner consistent with the servicing arrangements contemplated hereunder and that such agreements would not result in a withdrawal or a downgrading by any Rating Agency of the rating on any Class of Certificates. The Trustee is hereby
authorized to acknowledge, at the request of the Servicer, any Sub-Servicing Agreement that meets the requirements applicable to Sub- Servicing Agreements set forth in this Agreement and that is otherwise permitted under this Agreement. Each
Sub-Servicer shall be (i) authorized to transact business in the state or states where the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Sub-Servicer to perform its
obligations hereunder and under the Sub-Servicing Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Notwithstanding the provisions of any Sub-Servicing Agreement, any of the provisions of this Agreement relating to
agreements or arrangements between the Servicer or a Sub- Servicer or reference to actions taken through the Servicer or otherwise, the Servicer shall remain obligated and liable to the Depositor, the Trustee and the Certificateholders for the
servicing and administration of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Sub-Servicing Agreements or arrangements or by virtue of indemnification from
the Sub-Servicer and to the same extent and under the same terms and conditions as if the Servicer alone were servicing and administering the Mortgage Loans. Every Sub-Servicing Agreement entered into by the Servicer shall contain a provision giving
the successor Servicer the option to terminate such agreement in the event a successor Servicer is appointed. All actions of each Sub-Servicer performed pursuant to the related Sub-Servicing Agreement shall be performed as an agent of the Servicer
with the same force and effect as if performed directly by the Servicer. 
 For purposes of this Agreement, the Servicer shall be deemed to
have received any collections, recoveries or payments with respect to the Mortgage Loans that are received by a Sub- Servicer regardless of whether such payments are remitted by the Sub-Servicer to the Servicer. 
 Section 3.03 Successor Sub-Servicers. 
 Any Sub-Servicing Agreement shall provide that the Servicer shall be entitled to terminate any Sub-Servicing Agreement and to either itself directly service the related Mortgage Loans or enter into a Sub-Servicing Agreement with a successor
Sub-Servicer which qualifies under Section 3.02. Any Sub- Servicing Agreement shall include the provision that such agreement may be immediately terminated by any successor to the Servicer (which may be the Trustee or the Master Servicer)
without fee, in accordance with the terms of this Agreement, in the event that the Servicer (or any successor to the Servicer) shall, for any reason, no longer be the Servicer, (including termination due to a Servicer Event of Default). 

 

 79 

 Section 3.04 No Contractual Relationship Between Sub-Servicer, Trustee or the Certificateholders.

 Any Sub-Servicing Agreement and any other transactions or services relating to the Mortgage Loans involving a Sub-Servicer shall be deemed
to be between the Sub-Servicer and the Servicer alone and the Master Servicer, the Trustee and the Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to any
Sub-Servicer except as set forth in Section 3.05. The Servicer shall be solely liable for all fees owed by it to any Sub-Servicer, irrespective of whether the Servicer’s compensation pursuant to this Agreement is sufficient to pay such
fee. 
 Section 3.05 Assumption or Termination of Sub-Servicing Agreement by Successor Servicer. 
 In connection with the assumption of the responsibilities, duties and liabilities and of the authority, power and rights of the Servicer hereunder by a
successor Servicer (which may be the Master Servicer) pursuant to Section 8.02, it is understood and agreed that the Servicer’s rights and obligations under any Sub-Servicing Agreement then in force between the Servicer and a Sub-Servicer
shall be assumed simultaneously by such successor Servicer without act or deed on the part of such successor Servicer; provided, however, that any successor Servicer may terminate the Sub-Servicer. 
 The Servicer shall, upon the reasonable request of the Master Servicer, but at its own expense, deliver to the assuming party documents and records
relating to each Sub-Servicing Agreement and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreements to the assuming party. 
 The Servicing Fee payable to any such successor Servicer shall be payable from payments received on the Mortgage Loans in the amount and in the manner
set forth in this Agreement. 
 Section 3.06 Collection of Certain Mortgage Loan Payments. 
 The Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans, and shall, to the
extent such procedures shall be consistent with this Agreement and Accepted Servicing Practices, follow such collection procedures as it would follow with respect to mortgage loans comparable to the Mortgage Loans and held for its own account.
Consistent with the foregoing, the Servicer may in its discretion (i) waive any late payment charge or, if applicable, penalty interest or (ii) extend the due dates for the Monthly Payments due on a Mortgage Note; provided that any
extension pursuant to this clause shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder. In the event of any such arrangement pursuant to clause (ii) above, the Servicer shall make timely
P&I Advances on such Mortgage Loan during such extension pursuant to Section 5.03 and in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangement. 
  

 80 

 Notwithstanding the foregoing, in the event that any Mortgage Loan is in default or, in the judgment of
the Servicer, such default is reasonably foreseeable, the Servicer, consistent with Accepted Servicing Practices may waive, modify or vary any term of such Mortgage Loan (including modifications that change the Mortgage Rate, forgive the payment of
principal or interest or extend the final maturity date of such Mortgage Loan), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of such Mortgage Loan, or consent to the postponement
of strict compliance with any such term or otherwise grant indulgence to any Mortgagor if in the Servicer’s determination such waiver, modification, postponement or indulgence is not materially adverse to the interests of the Certificateholders
(taking into account any estimated Realized Loss that might result absent such action). 
 Section 3.07 Collection of Taxes, Assessments
and Similar Items; Servicing Accounts. 
 To the extent the terms of a Mortgage related to a Mortgage Loan provide for Escrow Payments,
the Servicer shall establish and maintain one or more accounts (the “Servicing Accounts”), into which all collections from the related Mortgagors (or related advances from Sub-Servicers) for the payment of taxes, assessments, fire, flood,
and hazard insurance premiums, and comparable items for the account of the Mortgagors (“Escrow Payments”) shall be deposited and retained. Servicing Accounts shall be Eligible Accounts. The Servicer shall deposit in the Servicing Accounts
on a daily basis and in no event later than the second Business Day after receipt, and retain therein, all Escrow Payments collected on account of the Mortgage Loans, for the purpose of effecting the timely payment of any such items as required
under the terms of this Agreement. Withdrawals of amounts from a Servicing Account may be made only to (i) effect timely payment of taxes, assessments, fire, flood, and hazard insurance premiums, and comparable items; (ii) reimburse itself
out of related collections for any Servicing Advances made pursuant to Section 3.01 (with respect to taxes and assessments) and Section 3.11 (with respect to fire, flood and hazard insurance); (iii) refund to Mortgagors any sums as
may be determined to be overages; (iv) pay interest to the Servicer or, if required and as described below, to Mortgagors on balances in the Servicing Account; or (v) clear and terminate the Servicing Account at the termination of the
Servicer’s obligations and responsibilities in respect of the Mortgage Loans under this Agreement in accordance with Article X. As part of its servicing duties, the Servicer shall pay to the Mortgagors interest on funds in Servicing Accounts,
to the extent required by law and, to the extent that interest earned on funds in the Servicing Accounts is insufficient, to pay such interest from its or their own funds, without any reimbursement therefor. Notwithstanding the foregoing, the
Servicer shall not be obligated to collect Escrow Payments if the related Mortgage Loan does not require such payments but the Servicer shall nevertheless be obligated to make Servicing Advances as provided in Section 3.01 and
Section 3.11. In the event the Servicer shall deposit in the Servicing Accounts any amount not required to be deposited therein, it may at any time withdraw such amount from the Servicing Accounts, any provision to the contrary notwithstanding.

 To the extent that a Mortgage does not provide for Escrow Payments, the Servicer (i) shall determine whether any such payments are
made by the Mortgagor in a manner and at a time that is necessary to avoid the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien and (ii) shall ensure that all insurance required to be maintained on
the Mortgaged Property pursuant to this Agreement is maintained. If any such payment has not been 

  

 81 

 
made and the Servicer receives notice of a tax lien with respect to the Mortgage Loan being imposed, the Servicer shall, promptly and to the extent required
to avoid loss of the Mortgaged Property, advance or cause to be advanced funds necessary to discharge such lien on the Mortgaged Property unless the Servicer determines the advance to be nonrecoverable. The Servicer assumes full responsibility for
the payment of all such bills and shall effect payments of all such bills irrespective of the Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments and shall make Servicing Advances to effect such payments
subject to its determination of recoverability. 
 Section 3.08 Collection Account and Distribution Account. 
 (a) On behalf of the Trust Fund, the Servicer shall establish and maintain one or more Collection Accounts, held in trust for the benefit of the Trustee
and the Certificateholders. On behalf of the Trust Fund, the Servicer shall deposit or cause to be deposited in the Collection Account on a daily basis and in no event later than two Business Days after receipt, as and when received or as otherwise
required hereunder, the following payments and collections received or made by it on or subsequent to the Cut-off Date other than amounts attributable to a Due Date on or prior to the Cut-off Date or payments received by it on or prior to the
Cut-off Date, but allocable to a Due Period subsequent thereto: 
 (i) all payments on account of principal, including
Principal Prepayments (but not Prepayment Charges), on the Mortgage Loans; 
 (ii) all payments on account of interest (net of
the related Servicing Fee and any Prepayment Interest Excess) on each Mortgage Loan; 
 (iii) all Insurance Proceeds and
Liquidation Proceeds (other than proceeds collected in respect of any particular REO Property) and all Subsequent Recoveries; 
 (iv) any amounts required to be deposited by the Servicer pursuant to Section 3.10 in connection with any losses realized on Permitted Investments with respect to funds held in the Collection Account; 
 (v) any amounts required to be deposited by the Servicer pursuant to the second paragraph of Section 3.11(a) in respect of any
blanket policy deductibles; 
 (vi) any Purchase Price or Substitution Shortfall Amount delivered to the Servicer and all
proceeds (net of amounts payable or reimbursable to the Servicer, the Master Servicer, the Trustee, the Custodian or the Securities Administrator) of Mortgage Loans purchased in accordance with Section 2.03, Section 3.13 or
Section 10.01; and 
 (vii) any Prepayment Charges collected by the Servicer and the Servicer Prepayment Charge Payment
Amounts in connection with the Principal Prepayment of any of the Mortgage Loans. 
 The foregoing requirements for deposit in the Collection
Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of late payment charges, assumption fees or other similar fees need not be deposited 

  

 82 

 
by the Servicer in the Collection Account and may be retained by the Servicer as additional compensation. In the event the Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding. 
 (b) On behalf of the Trust Fund, the Securities Administrator shall establish and maintain one or more accounts (such account or accounts, the
“Distribution Account”), held in trust for the benefit of the Trustee, the Trust Fund and the Certificateholders. On behalf of the Trust Fund, the Servicer shall deliver to the Securities Administrator in immediately available funds for
deposit in the Distribution Account on or before 12:00 noon New York time on the Servicer Remittance Date, that portion of the Available Distribution Amount (calculated without regard to the references in the definition thereof to amounts that may
be withdrawn from the Distribution Account) for the related Distribution Date then on deposit in the Collection Account and the amount of all Prepayment Charges collected by the Servicer in connection with the Principal Prepayment of any of the
Mortgage Loans then on deposit in the Collection Account. If the balance on deposit in the Collection Account exceeds $100,000 as of the commencement of business on any Business Day and the Collection Account constitutes an Eligible Account solely
pursuant to clause (ii) of the definition of “Eligible Account,” the Servicer shall, on or before 5:00 p.m. New York time on such Business Day, withdraw from the Collection Account any and all amounts payable or reimbursable to the
Depositor, the Servicer, the Trustee, the Master Servicer, the Securities Administrator or the Seller pursuant to Section 3.09(a) and shall pay such amounts to the Persons entitled thereto. 
 With respect to any remittance received by the Securities Administrator on or after the first Business Day following the Business Day on which such
payment was due, the Securities Administrator shall send written notice thereof to the Servicer. The Servicer shall pay to the Securities Administrator interest on any such late payment by the Servicer at an annual rate equal to Prime Rate (as
defined in the Wall Street Journal) plus one percentage point, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be paid by the Servicer to the Securities Administrator on the date such late payment is
made and shall cover the period commencing with the day following such first Business Day and ending with the Business Day on which such payment is made, both inclusive. The payment by the Servicer of any such interest, or the failure of the
Securities Administrator to notify the Servicer of such interest, shall not be deemed an extension of time for payment or a waiver of any Event of Default by the Servicer. 
 (c) Funds in the Collection Account maintained by the Servicer and funds in the Distribution Account may be invested in Permitted Investments in
accordance with the provisions set forth in Section 3.10. The Servicer shall give notice to the Trustee, the Securities Administrator and the Master Servicer of the location of the Collection Account maintained by it when established and prior
to any change thereof. The Securities Administrator shall give notice to the Servicer and the Depositor of the location of the Distribution Account when established and prior to any change thereof. 
 (d) Funds held in the Collection Account maintained by the Servicer at any time may be delivered by the Servicer in immediately available funds to the
Securities Administrator for deposit in the Distribution Account. In the event the Servicer shall deliver to the Securities 

  

 83 

 
Administrator for deposit in the Distribution Account any amount not required to be deposited therein, it may at any time request that the Securities
Administrator withdraw such amount from the Distribution Account and remit to it any such amount, any provision herein to the contrary notwithstanding. In no event shall the Securities Administrator incur liability as a result of withdrawals from
the Distribution Account at the direction of the Servicer in accordance with the immediately preceding sentence. In addition, the Servicer shall deliver to the Securities Administrator no later than the Servicer Remittance Date the amounts set forth
in clauses (i) through (iv) below: 
 (i) any P&I Advances, as required pursuant to Section 5.03;

 (ii) any amounts required to be deposited pursuant to Section 3.21(d) or 3.21(f) in connection with any REO Property;

 (iii) any amounts to be paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to
Section 10.01; and 
 (iv) any amounts required to be deposited pursuant to Section 3.22 in connection with any
Prepayment Interest Shortfalls. 
 Section 3.09 Withdrawals from the Collection Account and Distribution Account. 
 (a) The Servicer shall, from time to time, make withdrawals from the Collection Account for any of the following purposes or as described in
Section 5.03: 
 (i) to remit to the Securities Administrator for deposit in the Distribution Account the amounts
required to be so remitted pursuant to Section 3.08(b) or permitted to be so remitted pursuant to the first sentence of Section 3.08(d); 
 (ii) subject to Section 3.13(d), to reimburse itself (including any successor Servicer) for P&I Advances made by it, but only to the extent of amounts received which represent Late Collections (net of the
related Servicing Fees) of Monthly Payments on Mortgage Loans with respect to which such P&I Advances were made in accordance with the provisions of Section 5.03; 
 (iii) subject to Section 3.13(d), to pay itself any unpaid Servicing Fees and reimburse itself any unreimbursed Servicing Advances
with respect to each Mortgage Loan, but only to the extent of any Liquidation Proceeds and Insurance Proceeds received with respect to such Mortgage Loan or to the extent of funds held in the Collection Account for future distribution that were not
included in the Available Distribution Amount for the preceding Distribution Date; 
 (iv) to pay to itself as servicing
compensation (in addition to the Servicing Fee) on the Servicer Remittance Date any interest or investment income earned on funds deposited in the Collection Account; 
 (v) to pay itself or the Seller, as the case may be, with respect to each Mortgage Loan that has previously been purchased or replaced
pursuant to Section 2.03 all amounts received thereon not included in the Purchase Price or the Substitution Shortfall Amount; 
  

 84 

 (vi) to reimburse itself (including any successor Servicer) for any P&I Advance or
Servicing Advance previously made by it which it has determined to be a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance in accordance with the provisions of Section 5.03; 
 (vii) to reimburse itself or the Depositor for expenses incurred by or reimbursable to it or the Depositor, as the case may be, pursuant
to Section 3.01 or Section 7.03; 
 (viii) to reimburse itself or the Trustee, as the case may be, for expenses
reasonably incurred in respect of the breach or defect giving rise to the purchase obligation under Section 2.03 of this Agreement that were included in the Purchase Price of the related Mortgage Loan, including any expenses arising out of the
enforcement of the purchase obligation; 
 (ix) to pay, or to reimburse itself for advances in respect of, expenses incurred
in connection with any Mortgage Loan pursuant to Section 3.13(b); 
 (x) to pay to itself any Prepayment Interest Excess
on the Mortgage Loans to the extent not retained pursuant to Section 3.08(a)(ii)); and 
 (xi) to clear and terminate the
Collection Account pursuant to Section 10.01. 
 The Servicer shall keep and maintain separate accounting, on a Mortgage Loan by
Mortgage Loan basis, for the purpose of justifying any withdrawal from the Collection Account, to the extent held by or on behalf of it, pursuant to subclauses (ii), (iii), (v), (vi), (vii), (viii), (ix) and (x) above. 
 (b) The Securities Administrator shall, from time to time, make withdrawals from the Distribution Account, for any of the following purposes, without
priority: 
 (i) to make distributions to Certificateholders in accordance with Section 5.01; 
 (ii) to pay to itself, the Custodian, the Master Servicer and the Trustee amounts to which it is entitled pursuant to Section 9.05 or
any other provision of this Agreement and any Extraordinary Trust Fund Expenses; 
 (iii) to reimburse itself or the Master
Servicer pursuant to Section 8.02; 
 (iv) to pay any amounts in respect of taxes pursuant to Section 11.01(g)(v);

 (v) [Reserved]; 
 (vi) to pay the Credit Risk Management Fee to the Credit Risk Manager; and 
  

 85 

 (vii) to clear and terminate the Distribution Account pursuant to Section 10.01.

 Section 3.10 Investment of Funds in the Investment Accounts. 
 (a) The Servicer may direct, by means of written directions (which may be standing directions), any depository institution maintaining the Collection
Account to invest the funds in such Collection Account (for purposes of this Section 3.10, an “Investment Account”) in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand,
(i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Securities Administrator is the obligor thereon, and
(ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Securities Administrator is the obligor on such Permitted Investment. Amounts in the Distribution Account may be
invested in Permitted Investments as directed in writing by the Master Servicer and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Securities Administrator is the obligor thereon, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if
the Securities Administrator is the obligor thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds shall be made in the name of the Trustee (in its capacity as such) or in the name of a
nominee of the Trustee. The Securities Administrator shall be entitled to sole possession over each such investment in the Distribution Account and, subject to subsection (b) below, the income thereon, and any certificate or other instrument
evidencing any such investment shall be delivered directly to the Securities Administrator or its agent, together with any document of transfer necessary to transfer title to such investment to the Trustee or its nominee. In the event amounts on
deposit in the Collection Account maintained by the Servicer are at any time invested in a Permitted Investment payable on demand, the party with investment discretion over such Investment Account shall: 
 (x) consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted
Investment may otherwise mature hereunder in an amount equal to the lesser of (1) all amounts then payable thereunder and (2) the amount required to be withdrawn on such date; and 
 (y) demand payment of all amounts due thereunder promptly upon receipt by such party of written notice from the Servicer that such
Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account. 
 (b)
All income and gain realized from the investment of funds deposited in the Collection Account held by or on behalf of the Servicer, shall be for the benefit of the Servicer and shall be subject to its withdrawal in accordance with Section 3.09.
The Servicer shall deposit in the Collection Account maintained by the Servicer the amount of any loss incurred in respect of any such Permitted Investment made with funds in such account immediately upon realization of such loss. All earnings and
gain realized from the investment of funds deposited in the Distribution Account shall be for the benefit of the Master Servicer. The Master Servicer 

  

 86 

 
shall remit from its own funds for deposit into the Distribution Account the amount of any loss incurred on Permitted Investments in the Distribution
Account. 
 (c) Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any
Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Trustee may and, subject to Section 9.01 and Section 9.02(a)(v), shall, at the written direction of the Servicer, take such
action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings. 
 (d) The Trustee, the Master Servicer or their respective Affiliates are permitted to receive additional compensation that could be deemed to be in the Trustee’s or the Master Servicer’s economic self-interest for (i) serving
as investment adviser, administrator, shareholder servicing agent, custodian or sub-custodian with respect to certain of the Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and
(iii) effecting transactions in certain Permitted Investments. Such compensation shall not be considered an amount that is reimbursable or payable to the Trustee or the Master Servicer pursuant to Section 3.09 or 3.10 or otherwise payable
in respect of Extraordinary Trust Fund Expenses. Such additional compensation shall not be an expense of the Trust Fund. 
 Section 3.11
Maintenance of Hazard Insurance, Errors and Omissions and Fidelity Coverage and Primary Mortgage Insurance. 
 (a) The terms of each
Mortgage Note require the related Mortgagor to maintain fire, flood and hazard insurance policies. To the extent such policies are not maintained, the Servicer shall cause to be maintained for each Mortgaged Property fire and hazard insurance with
extended coverage as is customary in the area where the Mortgaged Property is located in an amount which is at least equal to the lesser of the current principal balance of such Mortgage Loan and the amount necessary to compensate fully for any
damage or loss to the improvements which are a part of such property on a replacement cost basis, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard
insurance policy. The Servicer shall also cause to be maintained fire and hazard insurance on each REO Property with extended coverage as is customary in the area where the Mortgaged Property is located in an amount which is at least equal to the
lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding principal balance of the related Mortgage Loan at the time it became an REO Property. The Servicer will comply in the
performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the Servicer under any such policies (other than amounts to be applied to the restoration or
repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with Accepted Servicing Practices, subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in
the Collection Account, subject to withdrawal pursuant to Section 3.09, if received in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.21, if received in respect of an REO Property. Any cost
incurred by the Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of

  

 87 

 
such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than
pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal
Emergency Management Agency as having special flood hazards, the Servicer will cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid principal
balance of the related Mortgage Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is
participating in such program). 
 In the event that the Servicer shall obtain and maintain a blanket policy with an insurer having a General
Policy Rating of A:X or better in Best’s Key Rating Guide or otherwise acceptable to Fannie Mae or Freddie Mac insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations to
cause fire and hazard insurance to be maintained on the Mortgaged Properties, it being understood and agreed that such policy may contain a deductible clause, in which case the Servicer shall, in the event that there shall not have been maintained
on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.11, and there shall have been one or more losses which would have been covered by such policy, deposit to the Collection Account
from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the Servicer agrees to prepare and present, on
behalf of itself, the Trustee, the Trust Fund and the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy. 
 (b) The Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the
performance of its respective obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans, unless the
Servicer, has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Fannie Mae or Freddie Mac, unless the Servicer has
obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Servicer shall be deemed to have complied with this provision if an Affiliate of the Servicer, has such errors and omissions and fidelity bond coverage and, by the terms of
such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days’ prior written notice to the
Trustee. 
 (c) The Servicer shall not take any action that would result in noncoverage under any applicable primary mortgage insurance
policy of any loss which, but for the actions of the Servicer would have been covered thereunder. The Servicer shall use its best efforts to keep in force and effect any applicable primary mortgage insurance policy and, to the extent that the
related Mortgage Loan requires the Mortgagor to maintain such insurance, any other primary mortgage insurance applicable to any Mortgage Loan. Except as required by applicable law or the related Mortgage Loan Documents, the Servicer shall not cancel
or refuse to renew any such 

  

 88 

 
primary mortgage insurance policy that is in effect at the date of the initial issuance of the related Mortgage Note and is required to be kept in force
hereunder. 
 The Servicer agrees to present on behalf of the Trustee and the Certificateholders claims to the applicable insurer under any
other primary mortgage insurance policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any primary mortgage insurance policies respecting defaulted Mortgage Loans. Pursuant to Section 3.08,
any amounts collected by the Servicer under any primary mortgage insurance policies shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.09. 
 Section 3.12 Enforcement of Due-on-Sale Clauses; Assumption Agreements. 
 The Servicer shall, to the extent it has knowledge of any conveyance of any Mortgaged Property by any Mortgagor (whether by absolute conveyance or by
contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause, if any,
applicable thereto; provided, however, that the Servicer shall not exercise any such rights if prohibited by law from doing so. If the Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale”
clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the Servicer shall enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed
to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The Servicer is also authorized to enter into a substitution of
liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no such substitution shall be
effective unless such person satisfies the then current underwriting criteria of the Servicer for mortgage loans similar to the Mortgage Loans. In connection with any assumption or substitution, the Servicer shall apply such underwriting standards
and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans owned solely by it. The Servicer shall not take or enter into any assumption and
modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable hazard insurance policy. Any fee collected by the Servicer in
respect of an assumption or substitution of liability agreement will be retained by the Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the
related Mortgage Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The Servicer shall notify the Trustee (or the Custodian) that any such substitution or assumption
agreement has been completed by forwarding to the Trustee (or the Custodian) the executed original of such substitution or assumption agreement, which document shall be added to the related Mortgage File and shall, for all purposes, be considered a
part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. 
 Notwithstanding the
foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or any other violation of its obligations 

  

 89 

 
hereunder by reason of any assumption of a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatever. For purposes of this Section 3.12, the term “assumption” is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an
assumption or substitution of liability agreement. 
 Section 3.13 Realization Upon Defaulted Mortgage Loans. 
 (a) The Servicer shall use its best efforts, consistent with Accepted Servicing Practices, to foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.06. The Servicer shall be
responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses will be recoverable as Servicing Advances by the Servicer as contemplated in Sections 3.09 and 3.21. The foregoing
is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from an Uninsured Cause, the Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall
determine in its discretion that such restoration will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses. 
 (b) Notwithstanding the foregoing provisions of this Section 3.13 or any other provision of this Agreement, with respect to any Mortgage Loan as to which the Servicer has received actual notice of, or has actual
knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property, the Servicer shall not, on behalf of the Trust Fund, either (i) obtain title to such Mortgaged Property as a result of or in lieu of foreclosure
or otherwise, or (ii) otherwise acquire possession of, or take any other action with respect to, such Mortgaged Property, if, as a result of any such action, the Trust Fund, the Trustee or the Certificateholders would be considered to hold
title to, to be a “mortgagee-in- possession” of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended from time to time, or any comparable law, unless the Servicer has also previously determined, based on its reasonable judgment and a prudent report prepared by an Independent Person who regularly conducts environmental audits using customary
industry standards, that: 
  

	 	(1)	such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trust Fund to take such actions as are
necessary to bring the Mortgaged Property into compliance therewith; and 

  

	 	(2)	there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes or
petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could
be required, that it would be in the best economic interest of the Trust Fund to take such actions with respect to the affected Mortgaged Property. 

  

 90 

 The cost of the environmental audit report contemplated by this Section 3.13 shall be advanced by
the Servicer, subject to the Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.09(a)(ix), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in
the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans. 
 If the Servicer determines, as described
above, that it is in the best economic interest of the Trust Fund to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials affecting any such Mortgaged Property, then the Servicer shall take such action as it deems to be in the best economic interest of
the Trust Fund. The cost of any such compliance, containment, cleanup or remediation shall be advanced by the Servicer, subject to the Servicer’s right to be reimbursed therefor from the Collection Account as provided in Sections 3.09(a)(iii)
or 3.09(a)(ix), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans. 
 (c) Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance
Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan, will be applied in the following order of priority: first, to reimburse the Servicer for any related unreimbursed Servicing Advances and P&I Advances, pursuant to
Section 3.09(a)(ii) or (a)(iii); second, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Distribution Date on which such amounts are to be distributed if not
in connection with a Final Recovery Determination; and third, as a recovery of principal of the Mortgage Loan. If the amount of the recovery so allocated to interest is less than the full amount of accrued and unpaid interest due on such Mortgage
Loan, the amount of such recovery will be allocated by the Servicer as follows: first, to unpaid Servicing Fees; and second, to the balance of the interest then due and owing. The portion of the recovery so allocated to unpaid Servicing Fees shall
be reimbursed to the Servicer pursuant to Section 3.09(a)(iii). The portion of the recovery allocated to interest (net of unpaid Servicing Fees) and the portion of the recovery allocated to principal of the Mortgage Loan shall be applied as
follows: first, to reimburse the Servicer for any related unreimbursed Advances in accordance with Section 3.09(a)(ii) and any other amounts reimbursable to the Servicer pursuant to Section 3.09, and second, as part of the amounts to be
transferred to the Distribution Account in accordance with Section 3.08(b). 
 Section 3.14 Trustee to Cooperate; Release of Mortgage
Files. 
 (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that
payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will promptly furnish to the Custodian, on behalf of the Trustee, two copies of a request for
release substantially in the form attached to this Agreement signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from 

  

 91 

 
a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required
to be deposited in the Collection Account have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the Servicer the related Mortgage File. Upon receipt of such certification and request, the
Custodian, on behalf of the Trustee, shall within five (5) Business Days release the related Mortgage File to the Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such
payment in full, the Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged
Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Collection Account. 
 (b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the Servicer (in form
reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the request of the Servicer, and delivery to the Custodian, on behalf of the Trustee, of two
copies of a request for release signed by a Servicing Officer substantially in the form attached to this Agreement (or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer),
release within five (5) Business Days the related Mortgage File held in its possession or control to the Servicer. Such trust receipt shall obligate the Servicer to return the Mortgage File to the Custodian on behalf of the Trustee, when the
need therefor by the Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the
Custodian, on behalf of the Trustee, to the Servicer. 
 Notwithstanding the foregoing, in connection with a Principal Prepayment in full of
any Mortgage Loan, the Master Servicer may request release of the related Mortgage File from the Custodian, in the event the Servicer fails to do so. 
 Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the Servicer, any court pleadings, requests for trustee’s sale or other documents prepared and delivered to the Trustee
and reasonably acceptable to it and necessary to the foreclosure or trustee’s sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a
deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be executed by the
Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien
upon completion of the foreclosure or trustee’s sale. So long as no Servicing Termination Event shall have occurred and be continuing, the Servicer shall have the right to execute any and all such court pleadings, requests and other documents
as attorney-in-fact for, and on behalf of the Trustee. Notwithstanding anything to the contrary herein, the Trustee shall in no way be 

  

 92 

 
liable or responsible for the willful malfeasance of the Servicer, or for any wrongful or negligent actions taken by the Servicer, while the Servicer is
acting pursuant to the powers granted to it in this paragraph. 
 Section 3.15 Servicing Compensation. 
 As compensation for the activities of the Servicer, hereunder, the Servicer shall be entitled to the Servicing Fee with respect to each Mortgage Loan
payable solely from payments of interest in respect of such Mortgage Loan, subject to Section 3.22. In addition, the Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance Proceeds or Liquidation Proceeds to the extent
permitted by Section 3.09(a)(iii) and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.21. The right to the Servicing Fee may not be transferred in whole or in part except in
connection with the transfer of all of the Servicer’s responsibilities under this Agreement to the extent permitted herein. 
 Additional servicing compensation in the form of assumption fees, late payment charges and other miscellaneous fees (other than Prepayment Charges) shall be retained by the Servicer only to the extent such fees or charges are received by
the Servicer. The Servicer shall also be entitled pursuant to Section 3.09(a)(iv) to withdraw from the Collection Account and pursuant to Section 3.21(b) to withdraw from any REO Account, as additional servicing compensation, interest or
other income earned on deposits therein, subject to Section 3.10. In addition, the Servicer shall be entitled to retain or withdraw from the Collection Account, pursuant to Section 3.09(a)(x), any Prepayment Interest Excess with respect to
the Mortgage Loans as additional servicing compensation. The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder and shall not be entitled to reimbursement therefor except as
specifically provided herein. 
 Section 3.16 Collection Account Statements. 
 Not later than twenty days after each Distribution Date, the Servicer shall forward to the Master Servicer and the Securities Administrator, and, upon
request, the Securities Administrator shall forward to the Trustee and the Depositor, a statement prepared by the institution at which the Collection Account is maintained setting forth the status of the Collection Account as of the close of
business on such Distribution Date and showing, for the period covered by such statement, the aggregate amount of deposits into and withdrawals from the Collection Account of each category of deposit specified in Section 3.08(a) and each
category of withdrawal specified in Section 3.09. Copies of such statement shall be provided by the Securities Administrator to any Certificateholder and to any Person identified to the Securities Administrator as a prospective transferee of a
Certificate, upon request at the expense of the requesting party, provided such statement is delivered by the Servicer to the Securities Administrator. 
 Section 3.17 Statement as to Compliance. 
 Each of the Servicer, Master Servicer and the Securities
Administrator shall use its best reasonable efforts to deliver (or otherwise make available) (and with respect to any calendar year during which the Trust’s annual report on Form 10K is required to be filed in accordance with the Exchange Act,
the Servicer, each of the Master Servicer and Securities Administrator shall 

  

 93 

 
use its best reasonable efforts to cause any Servicing Function Participant engaged by it to deliver) to the Securities Administrator on or before
March 1 of each year, but in no event later than March 15, commencing in March 2007, and, in turn, the Securities Administrator will forward to the Depositor, an Officer’s Certificate stating, as to the signer thereof, that:

 (i) a review of such party’s activities during the preceding calendar year or portion thereof and of such party’s
performance under this Agreement or such other applicable agreement in the case of a Servicing Function Participant, has been made under such officer’s supervision; and 
 (ii) to the best of such officer’s knowledge, based on such review, such party has fulfilled all of its obligations under this
Agreement or such other applicable agreement in the case of a Servicing Function Participant, in all material respects throughout such year or portion thereof, or, if there has been a failure to fulfill any such obligation in any material respect,
specifying each such failure known to such officer and the nature and status thereof. 
 In the event the Servicer, the Master Servicer, the
Securities Administrator or any Servicing Function Participant engaged by any such party is terminated or resigns pursuant to the terms of this Agreement, or any applicable agreement in the case of a Servicing Function Participant, as the case may
be, such party shall provide an Officer’s Certificate pursuant to this Section 3.17 or to such applicable agreement, as the case may be, notwithstanding any such termination, assignment or resignation. 
 Section 3.18 Assessments of Compliance and Accountant’s Attestation Reports. 
 On or before March 1 of each year, but in no event later than March 15, commencing in March 2007, the Servicer, the Master Servicer, the
Securities Administrator, and the Custodian, each at its own expense, shall furnish or otherwise make available, and with respect to any calendar year during which the Trust’s annual report on Form 10K is required to be filed in accordance with
the Exchange Act each such party shall cause any Servicing Function Participant engaged by it to furnish, each at its own expense, to the Securities Administrator and, in turn, the Securities Administration shall forward the Depositor, a report on
an assessment of compliance with the Relevant Servicing Criteria that contains (A) a statement by such party of its responsibility for assessing compliance with the Relevant Servicing Criteria, (B) a statement that such party used the
Relevant Servicing Criteria to assess compliance with the Relevant Servicing Criteria, (C) such party’s assessment of compliance with the Relevant Servicing Criteria as of and for the fiscal year covered by the Form 10-K required to be
filed pursuant to Section 5.09(a)(ii), including, if there has been any material instance of noncompliance with the Relevant Servicing Criteria, a discussion of each such failure and the nature and status thereof, and (D) a statement that
a registered public accounting firm has issued an attestation report on such party’s assessment of compliance with the Relevant Servicing Criteria as of and for such period. 
 No later than the end of each fiscal year for the Trust for which a 10-K is required to be filed, the Servicer, the Master Servicer and the Custodian
shall each forward to the Securities Administrator and, in turn, the Securities Administrator shall forward the Depositor the name of each Servicing Function Participant engaged by it and what Relevant Servicing Criteria will be 

  

 94 

 
addressed in the report on assessment of compliance prepared by such Servicing Function Participant (provided, however, that the Master
Servicer need not provide such information to the Securities Administrator so long as the Master Servicer and the Securities Administrator are the same Person). When the Servicer, the Master Servicer, the Custodian and the Securities Administrator
(or any Servicing Function Participant engaged by them) submit their assessments to the Securities Administrator, such parties will also at such time include the assessment and attestation pursuant to Section 3.18 of each Servicing Function
Participant engaged by it. 
 Promptly after receipt of each such report on assessment of compliance, (i) the Depositor shall review
each such report and, if applicable, consult with the Servicer, the Master Servicer, the Securities Administrator, the Custodian and any Servicing Function Participant engaged by such parties as to the nature of any material instance of
noncompliance with the Relevant Servicing Criteria by each such party, and (ii) the Securities Administrator shall confirm that the assessments, taken as a whole, address all of the Servicing Criteria and taken individually address the Relevant
Servicing Criteria for each party as set forth on Exhibit P and notify the Depositor of any exceptions. 
 In the event the Servicer, the
Master Servicer, the Securities Administrator, the Custodian, or any Servicing Function Participant engaged by any such party is terminated, assigns its rights and obligations under, or resigns pursuant to, the terms of this Agreement, or any other
applicable agreement, as the case may be, such party shall provide a report on assessment of compliance pursuant to this Section 3.18, or to such other applicable agreement, notwithstanding any such termination, assignment or resignation.

 On or before March 1 of each year, but in no event later than March 15, commencing in March 2007, the Servicer, the Master
Servicer, the Securities Administrator and the Custodian, each at its own expense, shall cause, (and with respect to any calendar year during which the Trust’s annual report on Form 10K is required to be filed in accordance with the Exchange
Act each such party shall cause any Servicing Function Participant engaged by it to cause), each at its own expense, a registered public accounting firm (which may also render other services to the Servicer, Master Servicer, the Trustee, the
Securities Administrator, or such other Servicing Function Participants, as the case may be) and that is a member of the American Institute of Certified Public Accountants to furnish an attestation report to the Securities Administrator and the
Depositor, to the effect that (i) it has obtained a representation regarding certain matters from the management of such party, which includes an assertion that such party has complied with the Relevant Servicing Criteria, and (ii) on the
basis of an examination conducted by such firm in accordance with standards for attestation engagements issued or adopted by the Public Company Accounting Oversight Board, it is expressing an opinion as to whether such party’s compliance with
the Relevant Servicing Criteria was fairly stated in all material respects, or it cannot express an overall opinion regarding such party’s assessment of compliance with the Relevant Servicing Criteria. In the event that an overall opinion
cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Such report must be available for general use and not contain restricted use language. 
 Promptly after receipt of each such assessment of compliance and attestation report, the Securities Administrator shall confirm that each assessment
submitted pursuant to Section 3.18 is coupled with an attestation meeting the requirements of this Section and notify the Depositor of any exceptions. 
  

 95 

 In the event the Servicer, the Master Servicer, the Securities Administrator, the Custodian or any
Servicing Function Participant engaged by any such party is terminated, assigns its rights and duties under, or resigns pursuant to the terms of, this Agreement, or any applicable custodial agreement, servicing agreement or sub-servicing agreement,
as the case may be, such party shall cause a registered public accounting firm to provide an attestation pursuant to this Section 3.18, or such other applicable agreement, notwithstanding any such termination, assignment or resignation.

 Section 3.19 [Reserved]. 
 Section 3.20 Access to Certain Documentation. 
 The Servicer shall provide to the Office of Thrift Supervision, the FDIC,
and any other federal or state banking or insurance regulatory authority that may exercise authority over any Certificate Owner, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations. Such access shall
be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Servicer designated by it. Nothing in this Section 3.20 shall limit the obligation of the Servicer to comply with any applicable
law prohibiting disclosure of information regarding the Mortgagors and the failure of the Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Nothing in this
Section 3.20 shall require the Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business. The Servicer shall not be required to make copies of or ship documents to any
Person unless provisions have been made for the reimbursement of the costs thereof. 
 Section 3.21 Title, Management and Disposition of
REO Property. 
 (a) The deed or certificate of sale of any REO Property shall be taken in the name of the Trustee, or its nominee, on
behalf of the Trust Fund and for the benefit of the Certificateholders. The Servicer, on behalf of REMIC I, shall either sell any REO Property by the close of the third calendar year following the calendar year in which REMIC I acquires ownership of
such REO Property for purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no later than 60 days before the day on which the three-year grace period would otherwise expire an extension of the three-year grace
period, unless the Servicer had delivered to the Trustee an Opinion of Counsel, addressed to the Trustee and the Depositor, to the effect that the holding by REMIC I of such REO Property subsequent to three years after its acquisition will not
result in the imposition on any Trust REMIC created hereunder of taxes on “prohibited transactions” thereof, as defined in Section 860F of the Code, or cause any Trust REMIC hereunder to fail to qualify as a REMIC under Federal law at
any time that any Certificates are outstanding. The Servicer shall manage, conserve, protect and operate each REO Property for the Certificateholders solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC created hereunder of any “income from non-permitted assets” within the
meaning of Section 860F(a)(2)(B) of the Code, or any “net income from foreclosure property” which is subject to taxation under the REMIC Provisions. 
  

 96 

 (b) The Servicer shall segregate and hold all funds collected and received in connection with the
operation of any REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect to REO Properties an account held in trust for the Trustee, on behalf of the Trust Fund and for the benefit of the
Certificateholders (the “REO Account”), which shall be an Eligible Account. The Servicer shall be permitted to allow the Collection Account to serve as the REO Account, subject to separate ledgers for each REO Property. The Servicer shall
be entitled to retain or withdraw any interest income paid on funds deposited in the REO Account. 
 (c) The Servicer shall have full power
and authority, subject only to the specific requirements and prohibitions of this Agreement, to do any and all things in connection with any REO Property as are consistent with the manner in which the Servicer manages and operates similar property
owned by it or any of its Affiliates, all on such terms and for such period as the Servicer deems to be in the best interests of Certificateholders. In connection therewith, the Servicer shall deposit, or cause to be deposited, on a daily basis in
the REO Account all revenues received by it with respect to an REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of such REO Property including, without limitation: 
 (i) all insurance premiums due and payable in respect of such REO Property; 
 (ii) all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon; and

 (iii) all costs and expenses necessary to maintain such REO Property. 
 To the extent that amounts on deposit in the REO Account with respect to an REO Property are insufficient for the purposes set forth in clauses
(i) through (iii) above with respect to such REO Property, the Servicer shall advance from its own funds such amount as is necessary for such purposes if, but only if, the Servicer would make such advances if the Servicer owned the REO
Property and if in the Servicer’s judgment, the payment of such amounts will be recoverable from the rental or sale of the REO Property. 
 Subject to compliance with applicable laws and regulations as shall at any time be in force, and notwithstanding the foregoing, the Servicer, on behalf of the Trust Fund, shall not: 
 (i) enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give rise to any income
that does not constitute Rents from Real Property; 
 (ii) permit any amount to be received or accrued under any New Lease
other than amounts that will constitute Rents from Real Property; 
 (iii) authorize or permit any construction on any REO
Property, other than the completion of a building or other improvement thereon, and then only if more than ten 

  

 97 

 
percent of the construction of such building or other improvement was completed before default on the related Mortgage Loan became imminent, all within the
meaning of Section 856(e)(4)(B) of the Code; or 
 (iv) allow any Person to Directly Operate any REO Property on any date
more than 90 days after its date of acquisition by the Trust Fund; 
 unless, in any such case, the Servicer has obtained an Opinion of Counsel, provided to
the Servicer and the Trustee, to the effect that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code at any time that it is held by REMIC I, in
which case the Servicer may take such actions as are specified in such Opinion of Counsel. 
 The Servicer may contract with any Independent
Contractor for the operation and management of any REO Property, provided that: 
 (i) the terms and conditions of any
such contract shall not be inconsistent herewith; 
 (ii) any such contract shall require, or shall be administered to
require, that the Independent Contractor pay all costs and expenses incurred in connection with the operation and management of such REO Property, including those listed above and remit all related revenues (net of such costs and expenses) to the
Servicer as soon as practicable, but in no event later than thirty days following the receipt thereof by such Independent Contractor; 
 (iii) none of the provisions of this Section 3.21(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Servicer of any of its duties and
obligations to the Trustee on behalf of the Trust Fund and for the benefit of the Certificateholders with respect to the operation and management of any such REO Property; and 
 (iv) the Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties and obligations in
connection with the operation and management of such REO Property. 
 The Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and obligations hereunder for indemnification of the Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such
indemnification. The Servicer shall be solely liable for all fees owed by it to any such Independent Contractor, irrespective of whether the Servicer’s compensation pursuant to Section 3.15 is sufficient to pay such fees. Any such
agreement shall include a provision that such agreement may be immediately terminated by the Trustee (as successor Servicer) or any other successor Servicer (including the Master Servicer) without fee, in the event the Servicer shall for any reason,
no longer be the Servicer (including termination due to a Servicer Event of Default). 
  

 98 

 (d) In addition to the withdrawals permitted under Section 3.21(c), the Servicer may from time to
time make withdrawals from the REO Account for any REO Property: (i) to pay itself unpaid Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer for unreimbursed Servicing Advances and
Advances made in respect of such REO Property or the related Mortgage Loan. On the Servicer Remittance Date, the Servicer shall withdraw from each REO Account maintained by it and deposit into the Distribution Account in accordance with
Section 3.08(d)(ii), for distribution on the related Distribution Date in accordance with Section 5.01, the income from the related REO Property received during the prior calendar month, net of any withdrawals made pursuant to
Section 3.21(c) or this Section 3.21(d). 
 (e) Subject to the time constraints set forth in Section 3.21(a), each REO
Disposition shall be carried out by the Servicer at such price and upon such terms and conditions as the Servicer shall deem necessary or advisable, as shall be normal and usual in accordance with Accepted Servicing Practices. 
 (f) The proceeds from the REO Disposition, net of any amount required by law to be remitted to the Mortgagor under the related Mortgage Loan and net of
any payment or reimbursement to the Servicer as provided above, shall be deposited in the Distribution Account in accordance with Section 3.08(d)(ii) on the Servicer Remittance Date in the month following the receipt thereof for distribution on
the related Distribution Date in accordance with Section 5.01. Any REO Disposition shall be for cash only (unless changes in the REMIC Provisions made subsequent to the Startup Day allow a sale for other consideration). 
 (g) The Servicer shall file information returns (and shall provide a certification of a Servicing Officer to the Master Servicer that such filings have
been made) with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and cancellation of indebtedness income with respect to any Mortgaged Property as
required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code. 
 Section 3.22 Obligations of the Servicer in Respect of Prepayment Interest Shortfalls; Relief Act Interest Shortfalls. 
 The Servicer shall deliver to the Securities Administrator for deposit into the Distribution Account on or before 12:00 noon New York time on the
Servicer Remittance Date from its own funds an amount (the “Compensating Interest”) equal to the lesser of (i) the aggregate amount of the Prepayment Interest Shortfalls attributable to prepayments in full on the Mortgage Loans for
the related Distribution Date resulting solely from voluntary Principal Prepayments received by the Servicer during the related Prepayment Period and (ii) the aggregate amount of the related Servicing Fees payable to the Servicer on such
Distribution Date and any Prepayment Interest Excess earned during the related Prepayment Period with respect to the Mortgage Loans. The Servicer shall not have the right to reimbursement for any amounts remitted to the Securities Administrator in
respect of this Section 3.22. The Servicer shall not be obligated to pay the amounts set forth in this Section 3.22 with respect to shortfalls resulting from the application of the Relief Act. 
  

 99 

 Section 3.23 Obligations of the Servicer in Respect of Mortgage Rates and Monthly Payments.

 In the event that a shortfall in any collection on or liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances that were made by the Servicer in a manner not consistent with the terms of the related Mortgage Note and this Agreement, the Servicer, upon discovery or receipt of notice
thereof, immediately shall deliver to the Securities Administrator for deposit in the Distribution Account from its own funds the amount of any such shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee, the Securities
Administrator and the Master Servicer, the Depositor and any successor Servicer in respect of any such liability. Such indemnities shall survive the termination or discharge of this Agreement. Notwithstanding the foregoing, this Section 3.23
shall not limit the ability of the Servicer to seek recovery of any such amounts from the related Mortgagor under the terms of the related Mortgage Note and Mortgage, to the extent permitted by applicable law. 
 Section 3.24 Reserve Fund. 
 (a) No
later than the Closing Date, the Securities Administrator shall establish and maintain with itself a separate, segregated trust account titled, “Reserve Fund, Wells Fargo Bank, N.A., as Securities Administrator, in trust for registered holders
of SG Mortgage Securities Trust 2006-OPT2, Asset-Backed Certificates, Series 2006-OPT2” which shall be an Eligible Account. 
 (b) On
each Distribution Date as to which there is a Net WAC Rate Carryover Amount payable to the Class A Certificates and/or the Mezzanine Certificates, the Securities Administrator has been directed by the Class CE Certificateholders to, and
therefore will, deposit into the Reserve Fund the amounts described in Section 5.01(h)(vi), rather than distributing such amounts to the Class CE Certificateholders. On each such Distribution Date, the Securities Administrator shall hold all
such amounts for the benefit of the Holders of the Class A Certificates and the Mezzanine Certificates, and will distribute such amounts to the Holders of the Class A Certificates and/or the Mezzanine Certificates in the amounts and
priorities set forth in Section 5.01(h). 
 (c) For federal and state income tax purposes, the Class CE Certificateholders will be
deemed to be the owners of the Reserve Fund and all amounts deposited into the Reserve Fund shall be treated as amounts distributed by REMIC III to the Holders of the Class CE Certificates. Upon the termination of the Trust, or the payment in full
of the Class A Certificates and the Mezzanine Certificates, all amounts remaining on deposit in the Reserve Fund will be released by the Trust and distributed to the Class CE Certificateholders or their designees. The Reserve Fund will be part
of the Trust but not part of any REMIC created hereunder and any payments to the Holders of the Class A Certificates or the Mezzanine Certificates of Net WAC Rate Carryover Amounts will not be payments with respect to a “regular
interest” in a REMIC within the meaning of Code Section 860(G)(a)(1). 
 (d) By accepting a Class CE Certificate, each Class CE
Certificateholder hereby agrees to direct the Securities Administrator, and the Securities Administrator hereby is directed, to deposit into the Reserve Fund the amounts described above on each Distribution Date as to 

  

 100 

 
which there is any Net WAC Rate Carryover Amount rather than distributing such amounts to the Class CE Certificateholders. By accepting a Class CE
Certificate, each Class CE Certificateholder further agrees that such direction is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance. 
 (e) At the direction of the Holders of a majority in Percentage Interest in the Class CE Certificates, the Securities Administrator shall direct any
depository institution maintaining the Reserve Fund to invest the funds in such account in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Securities Administrator or an Affiliate manages or advises such investment, and (ii) no
later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Securities Administrator or an Affiliate manages or advises such investment. If no investment direction of the Holders of a
majority in Percentage Interest in the Class CE Certificates with respect to the Reserve Fund is received by the Securities Administrator, the Securities Administrator shall invest the funds in the Wells Fargo Advantage Prime Investment Money Market
Fund so long as such fund is a Permitted Investment. 
 (f) For federal tax return and information reporting, the value of the right of the
Holders of the Class A and the Mezzanine Certificates to receive payments from the Reserve Fund in respect of any Net WAC Rate Carryover Amount shall be $10,000. 
 Section 3.25 Servicer Indemnification. 
 The Servicer agrees to indemnify the Trustee, Master
Servicer and the Securities Administrator, from, and hold the Trustee, Master Servicer and the Securities Administrator harmless against, any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred by any such
Person by reason of the Servicer’s willful misfeasance, bad faith or gross negligence in the performance of its duties under this Agreement or by reason of the Servicer’s reckless disregard of its obligations and duties under this
Agreement. Such indemnity shall survive the termination or discharge of this Agreement and the resignation or removal of the Servicer, the Trustee, the Master Servicer and the Securities Administrator. Any payment hereunder made by the Servicer to
any such Person shall be from the Servicer own funds, without reimbursement from REMIC I therefor. 
 Section 3.26 Solicitations.

 From and after the Closing Date, the Servicer agrees that it will not take any action or permit or cause any action to be taken by any of
its agents and Affiliates, or by any independent contractors or independent mortgage brokerage companies on the Servicer’s behalf, to personally, by telephone, mail or electronic mail, solicit the Mortgagor under any Mortgage Loan for the
purpose of refinancing such Mortgage Loan; provided, that the Servicer may solicit any Mortgagor for whom the Servicer has received a request for verification of mortgage, a request for demand for payoff, a mortgagor initiated written or
verbal communication indicating a desire to prepay the related Mortgage Loan, another mortgage company has pulled a credit report on the mortgagor or the mortgagor initiates a title search; provided further, it is understood and agreed 

  

 101 

 
that promotions undertaken by the Servicer or any of its Affiliates which (i) concern optional insurance products or other additional products or
(ii) are directed to the general public at large, including, without limitation, mass mailings based on commercially acquired mailing lists, newspaper, radio and television advertisements shall not constitute solicitation under this Section,
nor is the Servicer prohibited from responding to unsolicited requests or inquiries made by a Mortgagor or an agent of a Mortgagor. Furthermore, the Servicer shall be permitted to include in its monthly statements to borrowers or otherwise,
statements regarding the availability of the Servicer’s counseling services with respect to refinancing mortgage loans. 
 Notwithstanding the foregoing, solely during the sixty (60) day period ending on (a) in the case of fixed rate Mortgage Loans, the last day of the period during which Prepayment Charges apply under the terms of the related
Mortgage Loan Documents or (b) in the case of Adjustable Rate Mortgage Loans, the later of (i) the last day of the period during which Prepayment Charges apply under the terms of the related Mortgage Loan Documents and (ii) the last
day of the period, if any, during which the related Mortgage Rate is fixed and not variable under the terms of the related Mortgage Loan Documents, the Servicer may solicit the related Mortgagor to refinance such Mortgage Loan, in whole or in part.

 103 

 
its judgment, determines that the Servicer should be terminated in accordance with the terms hereof, or that a notice should be sent pursuant to the terms
hereof with respect to the occurrence of an event that, unless cured, would constitute an Event of Default by the Servicer, the Master Servicer shall notify the Servicer, the Seller and the Trustee thereof and the Master Servicer shall issue such

such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and
expenses in pursuing such action. 
 (c) The Master Servicer shall be entitled to be reimbursed by the Servicer (or from amounts on deposit
in the Distribution Account if the Servicer is unable to fulfill its obligations hereunder) for all reasonable out-of-pocket or third party costs associated with the transfer of servicing from the predecessor Servicer (or if the predecessor Servicer
is the Master Servicer, from the Servicer immediately preceding the Master Servicer), including without limitation, any reasonable out-of-pocket or third party costs or expenses associated with the complete transfer of all servicing data and the

 Section 4.05 Power to Act; Procedures. 
 The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions

on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages,
(iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions
of this Agreement; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 4.03, shall not permit the Servicer to) knowingly or intentionally take any action, or fail to take (or
fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause REMIC I, REMIC II or REMIC III
to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set
forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action will not would cause REMIC I, REMIC II or REMIC III
to fail to qualify as a REMIC or result in the imposition of a tax upon REMIC I, REMIC II or REMIC III, as the case may be. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney
prepared and delivered to it and reasonably acceptable to it by empowering the Master Servicer or the Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or
otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with this Agreement, and the Trustee shall execute and deliver such other
documents prepared and delivered to it and reasonably acceptable to it, as the Master Servicer or the Servicer may request, to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, in each

or the Servicer and shall be indemnified by the Master Servicer or the Servicer, as applicable, for any cost, liability or expense incurred by the Trustee in connection with such Person’s use or misuse of any such power of attorney). If the
Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the
“doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.10. In the performance of its duties hereunder,
the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee. 
  

 105 

 Section 4.06 Due-on-Sale Clauses; Assumption Agreements. 
 To the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Servicer to enforce such clauses in accordance
with this Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with this Agreement and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be
released from liability in accordance with this Agreement. 
 Section 4.07 Documents, Records and Funds in Possession of Master Servicer
To Be Held for Trustee. 
 (a) The Master Servicer shall transmit to the Trustee or Custodian such documents and instruments coming into

banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during
normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

proceeds disbursed to the Master Servicer in respect of such policies, bonds or contracts shall be promptly remitted to the Trustee for deposit in the Distribution Account upon receipt, except that any amounts realized that are to be applied to the

 Section 4.10 Maintenance of Primary Mortgage Insurance Policies. 
 (a) The Master Servicer shall not take, or permit the Servicer to take (to the extent such action is prohibited by this Agreement), any action that would result in noncoverage under any primary mortgage insurance

the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement. The Master Servicer shall not, and shall not permit the Servicer
to, cancel or refuse to renew any primary mortgage insurance policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement.

 The Trustee or the applicable Custodian, shall retain possession and custody of the originals (to the extent available) of any primary mortgage insurance
policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been

policies, any certificates of renewal, and such other documents or instruments that constitute part of any Mortgage File that come into the possession of the Master Servicer from time to time.

after the end of the calendar year of its acquisition by REMIC I unless (i) the Trustee shall have been supplied by the Servicer with an Opinion of Counsel to the effect that the holding by the Trust Fund of such REO Property subsequent to such
three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC hereunder as defined in section 860F of the Code or cause any REMIC hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) or (ii) the Servicer shall have applied for, prior to the expiration of
such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. The Master Servicer shall
cause the Servicer to protect and conserve, such REO Property in the manner and to the extent required by this Agreement, in accordance with the REMIC Provisions and in a manner that does not result in a tax on “net income from foreclosure
property” or cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code. 
 (b) The Master Servicer shall cause the Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the Collection Account.

Class of Certificates on each Distribution Date will be made to the Holders of the respective Class of record on the related Record Date (except as otherwise provided in Section 5.01(j) or Section 10.01 respecting the final distribution on
such Class), based on the aggregate Percentage Interest represented by their respective Certificates, and shall be made by wire transfer of immediately available funds to the account of any such Holder at a bank or other entity having appropriate
facilities therefor, if such Holder shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Certificates having an
initial aggregate Certificate Principal Balance that is in excess of the lesser of (i) $5,000,000 or (ii) two-thirds of the initial Certificate Principal Balance of such Class of Certificates, or otherwise by check mailed by first class
mail to the address of such Holder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office of the

 118 

 Each distribution with respect to a Book-Entry Certificate shall be paid to the Depository, as Holder
thereof, and the Depository shall be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing
such distribution to the Certificate Owners that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be
responsible for disbursing funds to the Certificate Owners that it represents. All such credits and disbursements with respect to a Book-Entry Certificate are to be made by the Depository and the Depository Participants in accordance with the
provisions of the Certificates. None of the Trustee, the Depositor, the Servicer, the Securities Administrator or the Master Servicer shall have any responsibility therefor except as otherwise provided by this Agreement or applicable law.

 (m) Subsequent Recoveries. On each Distribution Date, following all distributions on the Certificates pursuant to
Section 5.01, an amount equal to the amount of Subsequent Recoveries deposited into the Collection Account pursuant to Section 3.08 and included in the Available Distribution Amount for such Distribution Date will be applied to increase
the Certificate Principal Balance of the Class of Certificates with the Highest Priority up to the extent of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 5.05 and not previously reimbursed to such
Class with Net Monthly Excess Cashflow pursuant to Section 5.01(h). An amount equal to the amount of any remaining Subsequent Recoveries will be applied to increase the Certificate Principal Balance of the Class of Certificates with the next
Highest Priority, up to the amount of such Realized Losses previously allocated to that Class of Certificates pursuant to Section 5.05 and not previously reimbursed to such Class with Net Monthly Excess Cashflow pursuant to
Section 5.01(h), and so on. Holders of such Certificates will not be entitled to any distribution in respect of interest on the amount of such increases for any Accrual Period preceding the Distribution Date on which such increase occurs. Any
such increases shall be applied to the Certificate Principal Balance of each Certificate of such Class in accordance with its respective Percentage Interest. 
 (n) It is the intention of all of the parties hereto that the Class CE Certificates receive all principal and interest received by the Trust on the Mortgage Loans that is not otherwise distributable to any other Class
of Regular Certificates or REMIC Regular Interests. If the Securities Administrator determines that the Residual Certificates are entitled to any distributions, the Securities Administrator, prior to any such distribution to any Residual
Certificate, shall notify the Depositor of such impending distribution. Upon such notification, the Depositor will request an amendment to this Agreement to revise such mistake in the distribution provisions. The Residual Certificate Holders, by
acceptance of their Certificates, and the Servicer hereby agree and no further consent shall be necessary, notwithstanding anything to the contrary in Section 12.01 of this Agreement. 
 (o) The rights of the Certificateholders to receive distributions in respect of the Certificates, and all interests of the Certificateholders in such
distributions, shall be as set forth in this Agreement. None of the Holders of any Class of Certificates, the Trustee, the Servicer, the Securities Administrator or the Master Servicer shall in any way be responsible or liable to the Holders of any
other Class of Certificates in respect of amounts properly previously distributed on the Certificates. 
  

 119 

 (p) Except as otherwise provided in Section 10.01, whenever the Securities Administrator expects
that the final distribution with respect to any Class of Certificates will be made on the next Distribution Date, the Securities Administrator shall, no later than three (3) days before the related Distribution Date, mail to each Holder on such
date of such Class of Certificates a notice to the effect that: 
 (i) the Securities Administrator expects that the final
distribution with respect to such Class of Certificates will be made on such Distribution Date but only upon presentation and surrender of such Certificates at the office of the Securities Administrator therein specified, and 
 (ii) no interest shall accrue on such Certificates from and after the end of the related Accrual Period. 
 Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held in trust by the Securities Administrator and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 5.01(p) shall not have been surrendered for cancellation within six months after the time specified in such notice, the Securities Administrator shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Securities Administrator shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates but shall continue to hold any remaining funds for the benefit of
non-tendering Certificateholders. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in such trust fund. If within one year after the final notice any such
Certificates shall not have been surrendered for cancellation, the Securities Administrator shall pay to the Depositor all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest
shall accrue or be payable to any Certificateholder on any amount held in trust by the Securities Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) on the final Distribution Date for final payment
thereof in accordance with this Section 5.01(p). Any such amounts held in trust by the Securities Administrator shall be held uninvested in an Eligible Account. 
 (q) Notwithstanding anything to the contrary herein, (i) in no event shall the Certificate Principal Balance of a Class A Certificate or a Mezzanine Certificate be reduced more than once in respect of any
particular amount both (a) allocated to such Certificate in respect of Realized Losses pursuant to Section 5.06 and (b) distributed to the Holder of such Certificate in reduction of the Certificate Principal Balance thereof pursuant
to this Section 5.01 from Net Monthly Excess Cashflow and (ii) in no event shall the Uncertificated Balance of a REMIC I Regular Interest be reduced more than once in respect of any particular amount both (a) allocated to such REMIC I
Regular Interest in respect of Realized Losses pursuant to Section 5.06 and (b) distributed on such REMIC I Regular Interest in reduction of the Uncertificated Balance thereof pursuant to this Section 5.01.

 Section 5.03 Servicer Reports; P&I Advances. 
 (a) No later than the second Business Day following the Determination Date, the Servicer shall deliver to the Master Servicer and the Securities
Administrator a delinquency report containing substantially the information contained in the form set forth in Exhibit V-1, a monthly remittance advice containing substantially the information contained in the form set forth in Exhibit V-2, and a

the month preceding such Remittance Date together with such other information with respect to the Mortgage Loans and the related Distribution Date as is reasonably available to the Servicer as the Master Servicer or the Securities Administrator may

 (b) The amount of P&I Advances to be made by the Servicer on any Distribution Date shall equal, subject to Section 5.03(d),
(i) the aggregate amount of Monthly Payments (net of the related Servicing Fees), due during the related Due Period in respect of the Mortgage Loans, which Monthly Payments were delinquent as of the close of business on the related
Determination Date and (ii) with respect to each REO Property serviced by the Servicer, which REO Property was acquired during or prior to the related Prepayment Period and as to which such REO Property an REO Disposition did not occur during
the related Prepayment Period, an amount equal to the excess, if any, of the REO Imputed Interest on such REO Property for the most recently ended calendar month, over the net income from such REO Property deposited in the Collection Account
pursuant to Section 3.21 for distribution on such Distribution Date; provided, however, the Servicer shall not be required to make P&I Advances with respect to Relief Act Interest Shortfalls, or with respect to Prepayment Interest

 124 

 By 12:00 noon New York time on the Servicer Remittance Date, the Servicer shall remit in immediately
available funds to the Securities Administrator for deposit in the Distribution Account an amount equal to the aggregate amount of P&I Advances, if any, to be made in respect of the Mortgage Loans and REO Properties for the related Distribution
Date either (i) from its own funds or (ii) from the Collection Account, to the extent of any Amounts Held For Future Distribution on deposit therein (in which case it will cause to be made an appropriate entry in the records of the
Collection Account that Amounts Held For Future Distribution have been, as permitted by this Section 5.03, used by the Servicer in discharge of any such P&I Advance) or (iii) in the form of any combination of (i) and
(ii) aggregating the total amount of P&I Advances to be made by the Servicer with respect to the Mortgage Loans and REO Properties. In addition, the Servicer shall have the right to reimburse itself for any outstanding P&I Advance made
from its own funds from Amounts Held for Future Distribution. Any Amounts Held For Future Distribution used by the Servicer to make P&I Advances or to reimburse itself for outstanding P&I Advances shall be appropriately reflected in the
Servicer’s records and replaced by the Servicer by deposit in the Collection Account no later than the close of business on the Servicer Remittance Date immediately following the Due Period or Prepayment Period for which such amounts relate.
The Securities Administrator will notify the Servicer and the Master Servicer by the close of business on the Business Day prior to the Distribution Date in the event that the amount remitted by the Servicer to the Securities Administrator on such
date is less than the P&I Advances required to be made by the Servicer for the related Distribution Date. 
 (c) The obligation of the
Servicer to make such P&I Advances is mandatory, notwithstanding any other provision of this Agreement but subject to (d) below, and, with respect to any Mortgage Loan or REO Property, shall continue until a Final Recovery Determination in
connection therewith or the removal thereof from the Trust Fund pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section. 
 (d) Notwithstanding anything herein to the contrary, no P&I Advance or Servicing Advance shall be required to be made hereunder by the Servicer if such P&I Advance or Servicing Advance would, if made,
constitute a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, respectively. The determination by the Servicer that it has made a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance or that any proposed P&I
Advance or Servicing Advance, if made, would constitute a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, respectively, shall be evidenced by a certification of a Servicing Officer delivered to the Master Servicer. 
 (e) Subject to and in accordance with the provisions of Article VIII, in the event the Servicer fails to make any required P&I Advance, then the
Master Servicer (in its capacity as successor servicer) or any other successor Servicer shall be required to make such P&I Advance on the Distribution Date on which the Servicer was required to make such Advance, subject to its determination of
recoverability. 
 Section 5.04 Swap Account. 
 (a) No later than the Closing Date, on behalf of the Trust Fund, the Securities Administrator shall establish and maintain a separate, segregated trust account to be held in trust 

  

 125 

 
for the benefit of the Trustee, the Trust Fund and the Certificateholders. Such account shall be an Eligible Account and funds on deposit therein shall be
held separate and apart from, and shall not be commingled with, any other moneys, including, without limitation, other moneys of the Trust Fund held pursuant to this Agreement. Amounts therein shall be held uninvested. 
 (b) On the Business Day prior to each Distribution Date, prior to any distribution to any Certificate, the Securities Administrator shall deposit into
the Swap Account: (i) the amount of any Net Swap Payment or Swap Termination Payment (other than any Swap Termination Payment resulting from a Swap Provider Trigger Event) owed to the Swap Provider (after taking into account any upfront payment
received from the counterparty to a replacement swap agreement) from funds collected and received with respect to the Mortgage Loans prior to the determination of Available Distribution Amount and (ii) amounts received by the Securities
Administrator for distribution in accordance with subsection (d) below. For federal income tax purposes, any amounts paid to the Swap Provider on each Distribution Date shall first be deemed paid to the Swap Provider in respect of the REMIC III
Regular Interest Class CE-IO to the extent of the amount distributable on such Class on such Distribution Date, and any remaining amount shall be deemed paid to the Swap Provider in respect of a Class IO Distribution Amount (as defined below).

 (c) For federal income tax purposes, the Swap Account shall be owned by the majority Holder of the Class CE Certificates. 
 (d) On the Business Day prior to each Distribution Date, the Securities Administrator will be required to deposit into the Swap Account the Net Swap
Payment received from Swap Provider starting from the Distribution Date in January 2007 to (and including) the Distribution Date in December 2011 and the amount received from the Cap Agreement Provider to (and including) the Distribution Date in
June 2007. 
 (e) The Trustee shall treat the Holders of Certificates (other than the Class P, Class CE and Residual Certificates) as having
entered into a notional principal contract with respect to the Holders of the Class CE Certificates. Pursuant to each such notional principal contract, all Holders of Certificates (other than the Class P, Class CE and Residual Certificates) shall be
treated as having agreed to pay, on each Distribution Date, to the Holder of the Class CE Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the REMIC III Regular Interest
corresponding to such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class IO Distribution Amount”). A Class IO Distribution Amount payable from interest
collections shall be allocated pro rata among such Certificates based on the amount of interest otherwise payable to such Certificates, and a Class IO Distribution Amount payable from principal collections shall be allocated to the most
subordinate Class of Certificates with an outstanding principal balance to the extent of such balance. In addition, pursuant to such notional principal contract, the Holder of the Class CE Certificates shall be treated as having agreed to pay Net
WAC Rate Carryover Amounts to the Holders of the Certificates (other than the Class CE, Class P and Residual Certificates) in accordance with the terms of this Agreement. Any payments to the Certificates from amounts deemed received in respect of
this notional principal contract shall not be payments with respect to a Regular Interest in a REMIC within the meaning of Code Section 860G(a)(1). However, any payment from the Certificates (other than 

  

 126 

 
the Class CE, Class P and Residual Certificates) of a Class IO Distribution Amount shall be treated for tax purposes as having been received by the Holders
of such Certificates in respect of their interests in REMIC III and as having been paid by such Holders to the Trust pursuant to the notional principal contract. Thus, each Certificate (other than the Class P and Residual Certificates) shall be
treated as representing not only ownership of Regular Interests in REMIC III, but also ownership of an interest in, and obligations with respect to, a notional principal contract.

 Section 5.07 Tax Treatment of Swap Payments and Swap Termination Payments. 
 For federal income tax purposes, each holder of a Class A or Mezzanine Certificate is deemed to own an undivided beneficial ownership interest in a
REMIC regular interest and the right to receive payments from the Swap Account in respect of the Net WAC Rate Carryover Amount and the obligation to make payments to the Swap Account. For federal income tax purposes, the Securities Administrator
will account for payments to each Class A and Mezzanine Certificates as follows: each Class A and Mezzanine Certificate will be treated as receiving their entire payment from REMIC III (regardless of any Swap Termination Payment or
obligation under the Interest Rate Swap Agreement) and subsequently paying their portion of any Swap Termination Payment in respect of each such Class’ obligation under the Interest Rate Swap Agreement. In the event that any such Class is
resecuritized in a REMIC, the obligation under the Interest Rate Swap Agreement to pay any such Swap Termination Payment, will be made by one or more of the REMIC Regular Interests issued by the resecuritization REMIC subsequent to such REMIC
Regular Interest receiving its full payment from any such Class A or Mezzanine Certificate. Resecuritization of any Class A or Mezzanine Certificate in a REMIC will be permissible only if the Securities Administrator hereunder is the
trustee in such resecuritization. 
 The REMIC regular interest corresponding to a Class A or Mezzanine Certificate will be entitled to
receive interest and principal payments at the times and in the amounts equal to those made on the certificate to which it corresponds, except that (i) the maximum interest rate of that REMIC regular interest will equal the Net WAC Rate
computed for this purpose by limiting the Notional Amount of the Interest Rate Swap Agreement to the aggregate principal balance of the Mortgage Loans and (ii) any Swap Termination Payment will be treated as being payable solely from Net
Monthly Excess Cashflow. As a result of the foregoing, the amount of distributions and taxable income on the REMIC regular interest corresponding to a Class A or Mezzanine Certificate may exceed the actual amount of distributions on the
Class A or Mezzanine Certificate. 
 Section 5.08 Compliance with Withholding Requirements. 
 Notwithstanding any other provision of this Agreement, the Trustee and the Securities Administrator shall comply with all federal withholding
requirements respecting payments to Certificateholders of interest or original issue discount that the Trustee reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such 

  

 135 

 
withholding. In the event the Securities Administrator does withhold any amount from interest or original issue discount payments or advances thereof to any
Certificateholder pursuant to federal withholding requirements, the Securities Administrator shall indicate the amount withheld to such Certificateholders. 
 Section 5.09 Reports Filed with Securities and Exchange Commission. 
 (a) Within 15 days after each
Distribution Date (subject to permitted extensions under the Exchange Act), the Securities Administrator shall prepare and file on behalf of the Trust any Form 10-D required by the Exchange Act, in form and substance as required by the Exchange Act.
The Securities Administrator shall file each Form 10-D with a copy of the related Monthly Statement attached thereto. Any disclosure in addition to the Monthly Statement that is required to be included on Form 10-D (“Additional Form 10-D
Disclosure”) shall be reported by the parties set forth on Exhibit Q to the Depositor and the Securities Administrator and directed and approved by the Depositor pursuant to the following paragraph, and the Securities Administrator will have no
duty or liability for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure, except as set forth in the next paragraph. 
 (i) As set forth on Exhibit Q hereto, within 5 calendar days after the related Distribution Date, (i) the parties described on Exhibit Q shall be required to provide to the Securities Administrator and to the
Depositor, to the extent known by a responsible officer thereof, in EDGAR-compatible format, or in such other format as otherwise agreed upon by the Securities Administrator and such party, the form and substance of any Additional Form 10-D
Disclosure, if applicable, together with an Additional Disclosure Notification in the form of Exhibit S hereto (an “Additional Disclosure Notification”) and (ii) the Depositor will approve, as to form and substance, or disapprove, as
the case may be, the inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Securities Administrator has no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit Q of their duties under this
paragraph or proactively solicit or procure from such parties any Additional Form 10-D Disclosure information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection
with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph. 
  

	 	(A)	 After preparing the Form 10-D, the Securities Administrator shall, upon request, forward electronically a copy of the Form 10-D to the Depositor (provided
that such Form 10-D includes any Additional Form 10-D Disclosure). Within two Business Days after receipt of such copy, but no later than the 12th calendar day after the Distribution Date, the Depositor shall notify the Securities Administrator in
writing (which may be furnished electronically) of any changes to or approval of such Form 10-D. In the absence of receipt of any written changes or approval, or if the Depositor does not request a copy of a Form 10-D, the Securities Administrator
shall be entitled to assume that such Form 10-D is in final form and the Securities Administrator may proceed with the execution and filing of the Form 10-D. A duly authorized representative of the Master 

  

 136 

	 	 
Servicer shall sign each Form 10-D. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Securities
Administrator will follow the procedures set forth in Section 5.09(a)(v). Promptly (but no later than one Business Day) after filing with the Commission, the Securities Administrator will make available on its internet website a final executed
copy of each Form 10-D filed by the Securities Administrator. Each party to this Agreement acknowledges that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 5.09(a)(i) related to the
timely preparation, execution and filing of Form 10-D is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 5.09(a)(i). Form 10-D requires the registrant to indicate
(by checking “yes” or “no”) that it “(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required
to file such reports), and (2) has been subject to such filing requirements for the past 90 days.” The Depositor hereby represents to the Securities Administrator that the Depositor has filed all such required reports during the preceding
12 months and that it has been subject to such filing requirement for the past 90 days. The Depositor shall notify the Securities Administrator in writing, no later than the fifth calendar day after the related Distribution Date with respect to the
filing of a report on Form 10-D, if the answer to either question should be “no.” The Securities Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such Form 10-D. The Depositor
acknowledges that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 5.09(a)(i) related to the timely preparation, execution and filing of Form 10-D is also contingent upon the Servicer, the
Custodian and any Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Securities Administrator of any necessary
Additional Form 10-D Disclosure pursuant to any related servicing agreement, custodial agreement or any other applicable agreement. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage,
claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-D, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a timely basis, any
information from any other party hereto or Servicing Function Participant needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct. 

 (ii) On or prior to the 90th day after the end of each fiscal year of the Trust or such earlier date as may be required by the Exchange
Act (the “10-K Filing Deadline”) (it being understood that the fiscal year for the Trust ends on December 31st of each year), commencing in March 2007, the Securities Administrator shall prepare and file on behalf 

  

 137 

 
of the Trust a Form 10-K, in form and substance as required by the Exchange Act. Each such Form 10-K shall include the following items, in each case to the
extent they have been delivered to the Securities Administrator within the applicable time frames set forth in this Agreement, any related servicing agreement or custodial agreement: 
  

	 	(A)	an annual compliance statement for each Servicer, the Master Servicer, the Securities Administrator and any Servicing Function Participant engaged by such parties (together with
each Custodian, each, a “Reporting Servicer”) as described under Section 3.17 of this Agreement, any related servicing agreement or custodial agreement, provided, however, that the Securities Administrator, at its
discretion, may omit from the Form 10-K any annual compliance statement that is not required to be filed with such Form 10-K pursuant to Regulation AB; 

  

	 	(B)	(a) the annual reports on assessment of compliance with Servicing Criteria for each Reporting Servicer, as described under Section 3.18 of this Agreement, the any related
servicing agreement or custodial agreement, and (b) if each Reporting Servicer’s report on assessment of compliance with Servicing Criteria identifies any material instance of noncompliance, disclosure identifying such instance of
noncompliance, or if each Reporting Servicer’s report on assessment of compliance with Servicing Criteria is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not
included, provided, however, that the Securities Administrator, at its discretion, may omit from the Form 10-K any assessment of compliance or any attestation report described in clause (3) below that is not required to be filed
with such Form 10-K pursuant to Regulation AB; 

  

	 	(C)	(a) the registered public accounting firm attestation report for each Reporting Servicer, as described under Section 3.18 of this Agreement, any related servicing agreement or
custodial agreement, and (b) if any registered public accounting firm attestation report identifies any material instance of noncompliance, disclosure identifying such instance of noncompliance, or if any such registered public accounting firm
attestation report is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not included; and 

  

	 	(D)	a Sarbanes-Oxley Certification. 

 (iii) Any
disclosure or information in addition to (A) through (D) in subsection (ii) above that is required to be included on Form 10-K (“Additional Form 10-K Disclosure”) shall be reported by the parties set forth on Exhibit T to
the Depositor and the Securities Administrator and directed and approved by the Depositor pursuant to the following paragraph, and the Securities Administrator will have no duty or liability for any failure hereunder to determine or prepare any
Additional Form 10-K Disclosure, except as set forth in the next paragraph. 
  

 138 

	 	(A)	As set forth on Exhibit T hereto, on or before March 1, but in no event later than March 15 of each year that the Trust is subject to the Exchange Act reporting
requirements, commencing in 2007, (i) the parties described on Exhibit T shall be required to provide to the Securities Administrator and to the Depositor, to the extent known by a responsible officer thereof, in EDGAR-compatible format, or in
such other format as otherwise agreed upon by the Securities Administrator and such party, the form and substance of any Additional Form 10-K Disclosure, if applicable, together with an Additional Disclosure Notification, and (ii) the Depositor
will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Additional Form 10-K Disclosure on Form 10-K. The Securities Administrator has no duty under this Agreement to monitor or enforce the performance by the
parties listed on Exhibit T of their duties under this paragraph or proactively solicit or procure from such parties any Additional Form 10-K Disclosure information. The Depositor will be responsible for any reasonable fees and expenses assessed or
incurred by the Securities Administrator in connection with including any Additional Form 10-K Disclosure on Form 10-K pursuant to this paragraph. 

  

	 	(B)	 After preparing the Form 10-K, the Securities Administrator shall, upon request, forward electronically a copy of the Form 10-K to the Depositor. Within three
Business Days after receipt of such copy, but no later than March 25th, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-K. In the absence
of receipt of any written changes or approval, or if the Depositor does not request a copy of a Form 10-K, the Securities Administrator shall be entitled to assume that such Form 10-K is in final form and the Securities Administrator may proceed
with the execution and filing of the Form 10-K. A senior officer of the Master Servicer in charge of the master servicing function shall sign the Form 10-K. If a Form 10-K cannot be filed on time or if a previously filed Form 10-K needs to be
amended, the Securities Administrator will follow the procedures set forth in Section 5.09(a)(v). Promptly (but no later than one Business Day) after filing with the Commission, the Securities Administrator will make available on its internet
website a final executed copy of each Form 10-K filed by the Securities Administrator. The parties to this Agreement acknowledge that the performance by the Master Servicer and the Securities Administrator of its duties under this
Section 5.09(a)(iii) related to the timely preparation, execution and filing of Form 10-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 5.09(a)(iii),
Section 5.09(a)(iii)(C), Section 3.17 and Section 3.18. Form 10-K requires the registrant to indicate (by checking “yes” or “no”) that it “(1) has filed all reports required to be filed by Section 13 or
15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days.” The Depositor 

  

 139 

	 	 
hereby represents to the Securities Administrator that the Depositor has filed all such required reports during the preceding 12 months and that it has been
subject to such filing requirement for the past 90 days. The Depositor shall notify the Securities Administrator in writing, no later than the 15th calendar day of March in any year in which the Trust is subject to the reporting requirements of the
Exchange Act, if the answer to either question should be “no.” The Securities Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such Form 10-K. The Depositor acknowledges that the
performance by the Master Servicer and the Securities Administrator of its duties under this Section 5.09(iii) related to the timely preparation, execution and filing of Form 10-K is also contingent upon the Servicer, the Custodian and any
Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Securities Administrator of any necessary Additional Form 10-K
Disclosure, any annual statement of compliance and any assessment of compliance and attestation pursuant to any related servicing agreement, any custodial agreement or any other applicable agreement. Neither the Master Servicer nor the Securities
Administrator shall have any liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-K, where such failure results from the Securities
Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto or any Servicing Function Participant needed to prepare, arrange for execution or file such Form 10-K, not resulting from
its own negligence, bad faith or willful misconduct. 

  

	 	(C)	 Each Form 10-K shall include a Sarbanes-Oxley Certification. Each of the Servicer, the Master Servicer and the Securities Administrator shall use its best
reasonable efforts to provide, and each such party shall use its best reasonable efforts to cause any Servicing Function Participant engaged by it to provide, to the Person who signs the Sarbanes-Oxley Certification (the “Certifying
Person”), on or before March 1, but in no event later than March 15, of each year in which the Trust is subject to the reporting requirements of the Exchange Act and otherwise within a reasonable period of time upon request, a
certification (each, a “Back-Up Certification”), in the form attached hereto as Exhibit U, upon which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity’s officers, directors and
Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably rely. The senior officer of the Master Servicer in charge of the master servicing function shall serve as the Certifying Person on behalf of the
Trust. Such officer of the Certifying Person can be contacted by e-mail at cts.sec.notifications@wellsfargo.com or by facsimile at 410-715-2380. In the event any such party or any Servicing Function Participant engaged by such party is terminated or
resigns pursuant to the terms of this Agreement, or any applicable sub-servicing agreement, as the case may 

  

 140 

	 	 
be, such party shall provide a Back-Up Certification to the Certifying Person pursuant to this Section 5.09(a)(iii)(C) with respect to the period of
time it was subject to this Agreement or any applicable sub-servicing agreement, as the case may be. Notwithstanding the foregoing, (i) the Master Servicer and the Securities Administrator shall not be required to deliver a Back-Up
Certification to each other if both are the same Person and the Master Servicer is the Certifying Person and (ii) the Master Servicer shall not be obligated to sign the Sarbanes-Oxley Certification in the event that it does not receive any
Back-Up Certification required to be furnished to it pursuant to this section or any servicing agreement or custodial agreement. 

 (iv) Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such event, a “Reportable Event”), and if requested by the Depositor, the Securities
Administrator shall prepare and file on behalf of the Trust any Form 8-K, as required by the Exchange Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates. Any disclosure or
information related to a Reportable Event or that is otherwise required to be included on Form 8-K other than the initial Form 8-K (“Form 8-K Disclosure Information”) shall be reported by the parties set forth on Exhibit R to the Depositor
and the Securities Administrator and directed and approved by the Depositor pursuant to the following paragraph, and the Securities Administrator will have no duty or liability for any failure hereunder to determine or prepare any Form 8-K
Disclosure Information or any Form 8-K, except as set forth in the next paragraph. 
  

	 	(A)	As set forth on Exhibit R hereto, for so long as the Trust is subject to the Exchange Act reporting requirements, no later than the close of business (New York City time) on the 2nd
Business Day after the occurrence of a Reportable Event (i) the parties to this transaction shall be required to provide to the Securities Administrator and to the Depositor, to the extent known by a responsible officer thereof, in
EDGAR-compatible form, or in such other form as otherwise agreed upon by the Securities Administrator and such party, the form and substance of any Form 8-K Disclosure Information, if applicable, together with an Additional Disclosure Notification
and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Form 8-K Disclosure Information. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred
by the Securities Administrator in connection with including any Form 8-K Disclosure Information on Form 8-K pursuant to this paragraph. 

  

	 	(B)	 After preparing the Form 8-K, the Securities Administrator shall, upon request, forward electronically a copy of the Form 8-K to the Depositor. Promptly, but no
later than the close of business on the third Business Day after the Reportable Event, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 8-K. In the
absence of receipt of any 

  

 141 

	 	 
written changes or approval, or if the Depositor does not request a copy of a Form 8-K, the Securities Administrator shall be entitled to assume that such
Form 8-K is in final form and the Securities Administrator may proceed with the execution and filing of the Form 8-K. A duly authorized representative of the Master Servicer shall sign each Form 8-K. If a Form 8-K cannot be filed on time or if a
previously filed Form 8-K needs to be amended, the Securities Administrator will follow the procedures set forth in Section 5.09(a)(v). Promptly (but no later than one Business Day) after filing with the Commission, the Securities Administrator
will make available on its internet website a final executed copy of each Form 8-K filed by it. The parties to this Agreement acknowledge that the performance by the Master Servicer and the Securities Administrator of its duties under this
Section 5.09(a)(iv) related to the timely preparation, execution and filing of Form 8-K is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 5.09(a)(iv). The
Depositor acknowledges that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 5.09(a)(iv) related to the timely preparation, execution and filing of Form 8-K is also contingent upon the
Servicer, the Custodian and any Servicing Function Participant strictly observing deadlines no later than those set forth in this paragraph that are applicable to the parties to this Agreement in the delivery to the Securities Administrator of any
necessary Form 8-K Disclosure Information pursuant to any related servicing agreement, any custodial agreement or any other applicable agreement. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss,
expense, damage, claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 8-K, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a
timely basis, any information from any other party hereto or any Servicer, Custodian or Servicing Function Participant needed to prepare, arrange for execution or file such Form 8-K, not resulting from its own negligence, bad faith or willful
misconduct. 

 (v) On or prior to January 30 of the first year in which the Securities Administrator is
able to do so under applicable law, the Securities Administrator shall prepare and file a Form 15 Suspension Notification relating to the automatic suspension of reporting in respect of the Trust under the Exchange Act. 
  

	 	(A)	 On or prior to January 30 of each succeeding fiscal year (such fiscal year being a calendar year) for the Trust Fund after the filing of a Form 15 Suspension
Notification, the Securities Administrator shall determine if the aggregate number of Depository Participants holding a position in all the classes of Offered Certificates outstanding as of the beginning of such fiscal year is equal to or greater
than the number set forth in Section 15(d) of the Exchange Act (which as of the Closing Date is 300), which would cause the Trust Fund to again become subject to the reporting 

  

 142 

	 	 
requirements of the Exchange Act, in which case (i) such year is referred to in this Agreement as an “SEC Reporting Year,” and (ii) the
Securities Administrator shall recommence preparing and filing reports on Form 8-K, 10-D and Form 10-K as required pursuant to this Section until such time as the Securities Administrator is again able to file a Form 15 Suspension Notification with
respect to the Trust Fund with the Commission. 

  

	 	(B)	In the event that the Securities Administrator is unable to timely file with the Commission all or any required portion of any Form 8-K, 10-D or 10-K required to be filed by this
Agreement because required disclosure information was either not delivered to it or delivered to it after the delivery deadlines set forth in this Agreement or for any other reason, the Securities Administrator will promptly notify electronically
the Depositor. In the case of Form 10-D and 10-K, the parties to this Agreement will cooperate to prepare and file a Form 12b 25 and a 10-D/A and 10-K/A as applicable, pursuant to Rule 12b 25 of the Exchange Act. In the case of Form 8-K, the
Securities Administrator will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include such disclosure information on the next Form 10-D. In the event that any previously filed Form
8-K, 10-D or 10-K needs to be amended in connection with any Additional Form 10-D Disclosure (other than, in the case of Form 10-D, for the purpose of restating any Monthly Statement), Additional Form 10-K Disclosure or Form 8-K Disclosure
Information, the Securities Administrator will electronically notify the Depositor and such other parties to the transaction as are affected by such amendment, and such parties will cooperate to prepare any necessary 8-K/A, 10-D/A or 10-K/A. Any
Form 15, Form 12b 25 or any amendment to Form 8-K, 10-D or 10-K shall be signed by a duly authorized representative, or senior officer in charge of master servicing, as applicable, of the Master Servicer. The parties to this Agreement acknowledge
that the performance by the Master Servicer and the Securities Administrator of its duties under this Section 5.09(a)(v) related to the timely preparation, execution and filing of Form 15, a Form 12b 25 or any amendment to Form 8-K, 10-D or
10-K is contingent upon each such party performing its duties under this Section. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare, execute and/or timely file any such Form 15, Form 12b 25 or any amendments to Forms 8-K, 10-D or 10-K, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a
timely basis, any information from any other party hereto or any Servicing Function Participant needed to prepare, arrange for execution or file such Form 15, Form 12b 25 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from its own
negligence, bad faith or willful misconduct. 

  

 143 

 (b) The Securities Administrator shall have no responsibility to file any items other than those
specified in this Section 5.09; provided, however, the Securities Administrator will cooperate with the Depositor in connection with any additional filings with respect to the Trust Fund as the Depositor deems necessary under the
Exchange Act. Fees and expenses incurred by the Securities Administrator in connection with this Section 5.09 shall not be reimbursable from the Trust Fund. 
 (c) Each of the parties agrees to provide to the Securities Administrator such additional information related to such party as the Securities Administrator may reasonably request, including evidence of the
authorization of the person signing any certificate or statement, financial information and reports, and such other information related to such party or its performance hereunder. 
 (d) Any notice or notification required to be delivered by the Securities Administrator or Master Servicer to the Depositor pursuant to this 5.09, may be
delivered via facsimile to (212) 278-7320, via email to Abner.Figueroa@sgcib.com or telephonically by calling Abner Figueroa at (212) 278-5384. 
 (e) The Servicer shall indemnify and hold harmless the Master Servicer, the Securities Administrator, the Trustee and the Depositor and their respective officers, directors and affiliates (each, an “Indemnified
Party”), from and against any losses, damages, penalties, fines forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon (i) a breach of the obligations of the
Servicer under Section 3.17, Section 3.18 or Section 5.09, including any failure by the Servicer (or any Servicing Function Participant engaged by the Servicer), to provide any Back-Up Certification, annual statement of compliance,
annual assessment of compliance with Servicing Criteria or attestation report, any information, data or materials required to be included in any Exchange Act report or any other information or material when and as required under Sections 3.17, 3.18
or 5.09, or the Servicer’s negligence, bad faith or willful misconduct in connection therewith, (ii) any material misstatement or omission contained in any information, disclosure, report, certification, data, accountants’ letter or
other material provided under Sections 3.17, 3.18 and 5.09 to the Master Servicer or the Securities Administrator by or on behalf of the Servicer or on behalf of any Servicing Function Participant engaged by the Servicer), including any material
misstatement or material omission in (A) any Back-Up Certification, annual statement of compliance, annual assessment of compliance with Servicing Criteria or attestation report delivered by the Servicer, or by any Servicing Function
Participant engaged by it, pursuant to this Agreement, or (B) any Additional Form 10-D Disclosure, Additional Form 10-K Disclosure or Form 8-K Disclosure Information provided by the Servicer and (iii) any breach by the Servicer of a
representation or warranty set forth in Section 13.02 or in a writing furnished pursuant to Section 13.02(b) and made as of a date prior to the closing date of the related Securitization Transaction, to the extent that such breach is not
cured by such closing date, or any breach by the Company of a representation or warranty in a writing furnished pursuant to Section 13.02(b) to the extent made as of a date subsequent to such closing date. 
 If the indemnification provided for herein is unavailable or insufficient to hold harmless an Indemnified Party, then the Servicer agrees that it shall
contribute to the amount paid or payable by such Indemnified Party as a result of any claims, losses, damages or liabilities 

  

 144 

 
incurred by such Indemnified Party in such proportion as is appropriate to reflect the relative fault of such Indemnified Party on the one hand and the
Servicer on the other. 
 In the case of any failure of performance described in clause (e)(i) of this Section, the Servicer shall promptly
reimburse the Master Servicer, the Securities Administrator and the Depositor, as applicable, for all costs reasonably incurred by each such party in order to obtain the information, report, certification, accountants’ letter or other material
not delivered as required by the Servicer, or any Servicing Function Participant engaged by it. 
 This indemnification shall survive the
termination of this Agreement or the termination of any party to this Agreement. 
 (f) To the extent that, following the Closing Date, the
Depositor certifies that reports and certifications differing from those required under this Section 5.09 comply with the reporting requirements under the Exchange Act, the Master Servicer, the Servicer, the Securities Administrator and the
Trustee hereby agrees that it will reasonably cooperate to amend the provisions of this Section 5.09 in order to comply with such amended reporting requirements and such amendment of this Section 5.09. Any such amendment may result in the
reduction of the reports filed by the Depositor under the Exchange Act. Notwithstanding the foregoing, the Securities Administrator shall not be obligated to enter into any amendment pursuant to this Section that adversely affects its obligations
and immunities under this Agreement. 
 ARTICLE VI 
 THE CERTIFICATES 
 Section 6.01 The Certificates. 
 Each of the Class A Certificates, the Mezzanine Certificates, the Class P Certificates, the Class CE Certificates and the Residual Certificates
shall be substantially in the forms annexed hereto as exhibits, and shall, on original issue, be executed and authenticated by the Securities Administrator and delivered by the Trustee to or upon the order of the Depositor concurrently with the sale
and assignment to the Trustee of the Trust Fund. The Class A Certificates and the Mezzanine Certificates shall be initially evidenced by one or more Certificates representing a Percentage Interest with a minimum dollar denomination of $100,000
and integral dollar multiples of $1.00 in excess thereof, except that one Certificate of each such Class of Certificates may be in a different denomination so that the sum of the denominations of all outstanding Certificates of such Class shall
equal the Certificate Principal Balance or Notional Amount of such Class on the Closing Date. The Class P Certificates, the Class CE Certificates and the Residual Certificates are issuable in any Percentage Interests; provided, however, that
the sum of all such percentages for each such Class totals 100% and no more than ten Certificates of each Class may be issued and outstanding at any one time. 
 The Certificates shall be executed on behalf of the Trust by manual or facsimile signature on behalf of the Securities Administrator by a Responsible Officer. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Securities Administrator shall bind the Trust, 

  

 145 

 
notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not
hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless such Certificate shall have been manually authenticated by the Securities Administrator
substantially in the form provided for herein, and such authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be
dated the date of their authentication. Subject to Section 6.02, the Class A Certificates and the Mezzanine Certificates shall be Book-Entry Certificates. The other Classes of Certificates shall not be Book-Entry Certificates. 

The Class M-10 and Class M-11 Certificates offered and sold in reliance on the exemption from registration under Rule 144A shall be issued initially
in the form of one or more Global Securities with the applicable legends set forth in Exhibit A-8, added to the forms of such Certificates (each, a “Restricted Global Security”) and the Class M-10 and Class M-11 Certificates sold in
offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more Global Securities with the applicable legends set forth in Exhibit A-8, hereto added to the forms of such Certificates (each, a “Regulation S
Global Security”). 
 Section 6.02 Registration of Transfer and Exchange of Certificates. 
 (a) The Certificate Registrar shall cause to be kept at the Corporate Trust Office a Certificate Register in which, subject to such reasonable
regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Securities Administrator shall initially serve as Certificate
Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided. 
 Upon surrender for
registration of transfer of any Certificate at any office or agency of the Certificate Registrar maintained for such purpose pursuant to the foregoing paragraph and, in the case of a Residual Certificate, upon satisfaction of the conditions set
forth below, the Securities Administrator on behalf of the Trust shall execute and authenticate and the Securities Administrator on behalf of the Trust shall deliver, in the name of the designated transferee or transferees, one or more new
Certificates of the same aggregate Percentage Interest. 
 At the option of the Certificateholders, Certificates may be exchanged for other
Certificates in authorized denominations and the same aggregate Percentage Interests, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Securities
Administrator shall execute and authenticate on behalf of the Trust and the Securities Administrator shall deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered
for registration of transfer or exchange shall (if so required by the Securities Administrator or the Certificate Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer satisfactory to the Securities Administrator and
the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing. By acceptance of a Restricted Global Security or a Regulation S Global Security, whether upon original issuance or subsequent transfer, each
Holder or Certificate Owner of such a Certificate 

  

 146 

 
acknowledges the restrictions on the transfer of such Certificate set forth thereon and agrees that it will transfer such a Certificate only as provided
herein. 
 (b) Except as provided in paragraph (c) below, the Book-Entry Certificates shall at all times remain registered in the name
of the Depository or its nominee and at all times: (i) registration of such Certificates may not be transferred by the Securities Administrator except to another Depository; (ii) the Depository shall maintain book-entry records with
respect to the Certificate Owners and with respect to ownership and transfers of such Certificates; (iii) ownership and transfers of registration of such Certificates on the books of the Depository shall be governed by applicable rules
established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Securities Administrator shall for all purposes deal with the Depository as
representative of the Certificate Owners of the Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; (vi) the Securities Administrator may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the
Depository Participants with respect to indirect participating firms and Persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners; and (vii) the direct participants of the Depository shall have no
rights under this Agreement under or with respect to any of the Certificates held on their behalf by the Depository, and the Depository may be treated by the Securities Administrator and its agents, employees, officers and directors as the absolute
owner of the Certificates for all purposes whatsoever. 
 All transfers by Certificate Owners of Book-Entry Certificates shall be made in
accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owners. Each Depository Participant shall only transfer Book- Entry Certificates of Certificate Owners that it represents or of
brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures. The parties hereto are hereby authorized to execute a Letter of Representations with the Depository or take such other action as may be necessary
or desirable to register a Book-Entry Certificate to the Depository. In the event of any conflict between the terms of any such Letter of Representation and this Agreement, the terms of this Agreement shall control. 
 (c) If (i)(x) the Depository or the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to
discharge properly its responsibilities as Depository and (y) the Depositor is unable to locate a qualified successor or (ii) after the occurrence of a Servicer Event of Termination, the Certificate Owners of the Book-Entry Certificates
representing Percentage Interests of such Classes aggregating not less than 51% advise the Securities Administrator and Depository through the Financial Intermediaries and the Depository Participants in writing that the continuation of a book-entry
system through the Depository to the exclusion of definitive, fully registered certificates (the “Definitive Certificates”) to Certificate Owners is no longer in the best interests of the Certificate Owners. Upon surrender to the
Certificate Registrar of the Book-Entry Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Securities Administrator shall, at the Depositor’s expense, in the case of (i) or
(ii) above, or the Servicer’s expense, in the case of (iii) above, execute on behalf of the Trust and authenticate the Definitive 

  

 147 

 
Certificates. Neither the Depositor, the Servicer, the Master Servicer, the Trustee nor the Securities Administrator shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates, the Securities Administrator, the Trustee, the Certificate Registrar, the Master
Servicer, the Servicer and the Depositor shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder. 
 (d)
No transfer, sale, pledge or other disposition of any Class M-10, Class M-11 and Class CE Certificate, Class P Certificate or Residual Certificate (the “Private Certificates”) shall be made unless such disposition is exempt from the
registration requirements of the Securities Act, and any applicable state securities laws or is made in accordance with the Securities Act and any applicable state securities laws. In the event of any such transfer (other than in connection with
(i) the initial transfer of any such Certificate by the Depositor to an Affiliate of the Depositor or, in the case of the Class R Certificates, the first transfer by an Affiliate of the Depositor, (ii) the transfer of any such Class CE,
Class P or Residual Certificate to the issuer under the Indenture or the indenture trustee under the Indenture or (iii) a transfer of any such Class CE, Class P or Residual Certificate from the issuer under the Indenture or the indenture
trustee under the Indenture to the Depositor or an Affiliate of the Depositor), the Securities Administrator shall require the transferor to execute a transferor certificate (in substantially the form attached hereto as Exhibit L) and, in the case
of Certificates offered and sold in reliance on the exemption from registration under Rule 144A, the transferee to execute an investment letter (in substantially the form attached hereto as Exhibit J) acceptable to and in form and substance
reasonably satisfactory to the Depositor and the Securities Administrator certifying to the Depositor and the Securities Administrator the facts surrounding such transfer, which investment letter shall not be an expense of the Securities
Administrator or the Depositor. The Holder of a Class CE Certificate, Class P Certificate or Residual Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Securities Administrator and the Depositor against any
liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws. 
 (e) (i)
Notwithstanding the foregoing, (A) in the event of any such transfer of any Ownership Interest in any Restricted Global Security, except with respect to the initial transfer of any such Ownership Interest by the Depositor, such transfer shall
be required to be made in reliance upon Rule 144A under the Securities Act, and the transferor will be deemed to have made each of the transferor representations and warranties set forth Exhibit L hereto in respect of such interest as if it was
evidenced by a Definitive Certificate and the transferee will be deemed to have made each of the transferee representations and warranties set forth Exhibit J hereto in respect of such interest as if it was evidenced by a Definitive Certificate and
(B), in the event of any such transfer of any Ownership Interest in any Regulation S Global Security, except with respect to the initial transfer of any such Ownership Interest by the Depositor, such transfer shall be required to be made in reliance
upon Regulation S under the 1933 Act, and (x) the transferor of such a Certificate shall be deemed to have represented and warranted that such Certificates are being offered, resold, pledged or otherwise transferred only (A) to a person
which the seller reasonably believes is a “qualified institutional buyer” (as defined in Rule 144A under the 1933 Act), that is purchasing such Certificates for its own account or for the account of a “qualified institutional
buyer” to which notice is given that the transfer is being made in reliance on Rule 144A or (B) in an offshore transaction (as defined in Regulation S) in 

  

 148 

 
compliance with the provisions of Regulation S, in each case in compliance with the requirements of this Agreement, and (y) and the transferee of such a
Certificate shall be deemed to have represented and warranted that (i) such Person (A) if the offer or sale was made to it prior to the expiration of the 40-day distribution compliance period within the meaning of Regulation S, is not a
U.S. person and (B) was, at the time the buy order was originated, outside the United States and (ii) such Person understands that such Certificates have not been registered under the 1933 Act, and that (x) until the expiration of the
40-day distribution compliance period (within the meaning of Regulation S), no offer, sale, pledge or other transfer of such Certificates or any interest therein shall be made in the United States or to or for the account or benefit of a U.S. person
and (y) if in the future it decides to offer, resell, pledge or otherwise transfer such Certificates, such Certificates may be offered, resold, pledged or otherwise transferred only (A) to a person which the seller reasonably believes is a
“qualified institutional buyer”, that is purchasing such Certificates for its own account or for the account of a “qualified institutional buyer” to which notice is given that the transfer is being made in reliance on Rule 144A
or (B) in an offshore transaction (as defined in Regulation S) in compliance with the provisions of Regulation S, in each case in compliance with the requirements of this Agreement. 
 The Certificate Owner of any such Ownership Interest in any such Restricted Global Security or Regulation S Global Security desiring to effect such
transfer shall, and does hereby agree to, indemnify the Securities Administrator and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws. 
 (ii) Notwithstanding any provision to the contrary herein, so long as a Global Security representing any of the Class M-10 or Class M-11
Certificates remains outstanding and is held by or on behalf of DTC, transfers of a Global Security representing any such Certificates, in whole or in part, shall only be made in accordance with Section 6.02. 
  

	 	(A)	Subject to clauses (B) and (C) of this Section 6.02(d)(iii), transfers of a Global Security representing any of the Class M-10 or Class M-11 Certificates shall be
limited to transfers of such Global Security, in whole or in part, to nominees of DTC or to a successor of DTC or such successor’s nominee. 

  

	 	(B)	 Restricted Global Security to Regulation S Global Security. If a holder of a beneficial interest in a Restricted Global Security deposited with or on behalf
of DTC wishes at any time to exchange its interest in such Restricted Global Security for an interest in a Regulation S Global Security, or to transfer its interest in such Restricted Global Security to a Person who wishes to take delivery thereof
in the form of an interest in a Regulation S Global Security, such holder, provided such holder is not a U.S. person, may, subject to the rules and procedures of DTC, exchange or cause the exchange of such interest for an equivalent
beneficial interest in the Regulation S Global Security. Upon receipt by the Certificate Registrar of (I) instructions from DTC directing the Certificate Registrar to cause to be credited a beneficial interest in a Regulation S Global 

  

 149 

	 	 
Security in an amount equal to the beneficial interest in such Restricted Global Security to be exchanged but not less than the minimum denomination
applicable to such holder’s Certificates held through a Regulation S Global Security, (II) a written order given in accordance with DTC’s procedures containing information regarding the participant account of DTC 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 (III) a certificate in the form of Exhibit O-1 hereto given by the holder of such beneficial interest stating that
the exchange or transfer of such interest has been made in compliance with the transfer restrictions applicable to the Regulation S Global Securities, including that the holder is not a U.S. person, and pursuant to and in accordance with Regulation
S, the Certificate Registrar shall reduce the principal amount of the Restricted Global Security and increase the principal amount of the Regulation S Global Security by the aggregate principal amount of the beneficial interest in the Restricted
Global Security 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 Security equal to the reduction in the principal amount of the Restricted Global Security. 

  

	 	(C)	 Regulation S Global Security to Restricted Global Security. If a holder of a beneficial interest in a Regulation S Global Security deposited with or on
behalf of DTC wishes at any time to transfer its interest in such Regulation S Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Restricted Global Security, such holder may, subject to the rules and
procedures DTC, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Restricted Global Security. Upon receipt by the Certificate Registrar of (I) instructions from DTC directing the Certificate Registrar to
cause to be credited a beneficial interest in a Restricted Global Security in an amount equal to the beneficial interest in such Regulation S Global Security to be exchanged but not less than the minimum denomination applicable to such holder’s
Certificates held through a Restricted Global Security, to be exchanged, such instructions to contain information regarding the participant account with DTC to be credited with such increase, and (II) a certificate in the form of Exhibit O-2 hereto
given by the holder of such beneficial interest and stating, among other things, that the Person transferring such interest in such Regulation S Global Security reasonably believes that the Person acquiring such interest in a Restricted Global
Security is a “qualified institutional buyer” (as such term is defined in Rule 144A under the 1933 Act), is obtaining such beneficial interest in a transaction meeting the requirements of Rule 144A and in accordance with any applicable
securities laws of any State of the United States or any other jurisdiction, then the Certificate Registrar will reduce the principal amount of the Regulation S Global Security and increase the principal amount of the 

  

 150 

	 	 
Restricted Global Security by the aggregate principal amount of the beneficial interest in the Regulation S Global Security to be transferred and the
Certificate Registrar shall instruct DTC, 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 Restricted Global Security equal to the reduction
in the principal amount of the Regulation S Global Security. 

  

	 	(D)	Other Exchanges. In the event that a Global Security representing a Restricted Note is exchanged for Certificates in definitive registered form, pursuant to
Section 6.02(c), such Certificates may be exchanged for one another only in accordance with such procedures as are substantially consistent with the provisions above (including certification requirements intended to insure that such transfers
comply with Rule 144A, or are to non U.S. persons in compliance with Regulation S under the 1933 Act, as the case may be and a requirement that the Certificate Owner make the certifications set forth in Section 6.02(e) above), and as may be
from time to time adopted by the Securities Administrator. 

  

	 	(E)	Restrictions on U.S. Transfers. Transfers of interests in a Regulation S Global Security to U.S. persons shall be limited to transfers made pursuant to the provisions of
Section 6.02(d)(iii)(C). 

 (f) (i) In the case of any Class A, Class M, Class CE, Class P or Residual Certificate
presented for registration in the name of any Person, the prospective transferee shall be required to provide the Depositor and the Securities Administrator with a certification to the effect set forth in Exhibit N (provided, however
that such certification shall have been deemed to have been given by a Beneficial Owner who acquires a Book-Entry Certificate), which the Securities Administrator may rely upon without further inquiry or investigation, or such other certifications
as the Securities Administrator may deem desirable or necessary in order to establish that such transferee or the Person in whose name such registration is requested is not an employee benefit plan or other plan subject to the prohibited transaction
provisions of ERISA or Section 4975 of the Code (a “Plan”), or any Person (including, without limitation, an insurance company investing its general account, an investment manager, a named fiduciary or a trustee of any Plan) who is
using “plan assets,” within the meaning of the U.S. Department of Labor regulation promulgated at 29 C.F.R. § 2510.3-101 (as modified by Section 3(42) of ERISA), of any Plan (a “Plan Investor”), to effect such
acquisition. 
 (ii) Any Transferee of a Class A, Class M, Class CE, Class P or Residual Certificate that does not
deliver the certification referred to in clause (i) above will be deemed to have represented by virtue of its acquisition or holding of such Certificate (or any interest therein) that such Transferee is not a Plan or a Plan Investor.

 (iii) If any Class A, Class M, Class CE, Class P or Residual Certificate (or any interest therein) is acquired or held
by any Person that does not satisfy the conditions described in paragraph (ii) above, then the last preceding Transferee that is not a Plan or a Plan Investor shall be restored, to the extent permitted by law, to all rights and 

  

 151 

 
obligations as Certificate Owner thereof retroactive to the date of such Transfer of such Certificate. The Securities Administrator shall be under no
liability to any Person for making any payments due on such Certificate to such preceding Transferee. 
 (iv) Any purported
Certificate Owner whose acquisition or holding of any Class A, Class M, Class CE, Class P or Residual Certificate (or any interest therein) was effected in violation of the restrictions in this Section 6.02(f) shall indemnify and hold
harmless the Depositor, the Securities Administrator, the Trustee, the Master Servicer, any underwriter and the Trust Fund from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition
or holding. 
 (g) (i) (Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the
acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably authorized the Securities Administrator or its designee under clause (iii)(A) below to deliver payments to a Person
other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring
any Ownership Interest in a Residual Certificate are expressly subject to the following provisions: 
  

	 	(A)	Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Securities Administrator of any
change or impending change in its status as a Permitted Transferee. 

  

	 	(B)	In connection with any proposed Transfer of any Ownership Interest in a Residual Certificate, the Securities Administrator shall require delivery to it, and shall not register the
Transfer of any Residual Certificate until its receipt of, 

 (i) an affidavit and agreement (a “Transfer
Affidavit and Agreement,” in the form attached hereto as Exhibit K) from the proposed Transferee, in form and substance satisfactory to the Securities Administrator, representing and warranting, among other things, that it is a Permitted
Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is not a Permitted Transferee, that for so long as it retains its
Ownership Interest in a Residual Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 6.02(f) and agrees to be bound by them, and 
 (ii) a certificate, in the form attached hereto as Exhibit L, from the Holder wishing to transfer the Residual Certificate, in form
and substance satisfactory to the Securities Administrator, representing and warranting, among other things, that no purpose of the proposed Transfer is to impede the assessment or collection of tax. 
  

 152 

	 	(C)	Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed Transferee under clause (B) above, if a Responsible Officer of the Securities Administrator who
is assigned to this Agreement has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Residual Certificate to such proposed Transferee shall be effected. 

  

	 	(D)	Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (x) to require a Transfer Affidavit and Agreement from any other Person to whom
such Person attempts to transfer its Ownership Interest in a Residual Certificate and (y) not to transfer its Ownership Interest unless it provides a certificate to the Securities Administrator in the form attached hereto as Exhibit L.

  

	 	(E)	Each Person holding or acquiring an Ownership Interest in a Residual Certificate, by purchasing an Ownership Interest in such Certificate, agrees to give the Securities
Administrator written notice that it is a “pass-through interest holder” within the meaning of Temporary Treasury Regulations Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Residual Certificate, if
it is, or is holding an Ownership Interest in a Residual Certificate on behalf of, a “pass-through interest holder.” 

 (ii) The Securities Administrator shall register the Transfer of any Residual Certificate only if it shall have received the Transfer Affidavit and Agreement, a certificate of the Holder requesting such transfer in
the form attached hereto as Exhibit L and all of such other documents as shall have been reasonably required by the Securities Administrator as a condition to such registration. Transfers of the Residual Certificates to Non-United States Persons and
Disqualified Organizations (as defined in Section 860E(e)(5) of the Code) are prohibited. 
  

	 	(A)	 If any Disqualified Organization shall become a holder of a Residual Certificate, then the last preceding Permitted Transferee shall be restored, to the extent
permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. If a Non-United States Person shall become a holder of a Residual Certificate, then the last
preceding United States Person shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. If a transfer of a Residual
Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E-1 or Section 1.860G-3, then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights and
obligations as Holder thereof retroactive to the date of registration of 

  

 153 

	 	 
such Transfer of such Residual Certificate. The Securities Administrator shall be under no liability to any Person for any registration of Transfer of a
Residual Certificate that is in fact not permitted by this Section 6.02(f) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this
Agreement. 

  

	 	(B)	If any purported Transferee shall become a Holder of a Residual Certificate in violation of the restrictions in this Section 6.02(f) and to the extent that the retroactive
restoration of the rights of the Holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Securities Administrator shall have the right, without notice to the holder or any prior
holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Depositor on such terms as the Depositor may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in
accordance with the instructions of the Securities Administrator. Such purchaser may be the Securities Administrator itself or any Affiliate of the Securities Administrator. The proceeds of such sale, net of the commissions (which may include
commissions payable to the Securities Administrator or its Affiliates), expenses and taxes due, if any, will be remitted by the Securities Administrator to such purported Transferee. The terms and conditions of any sale under this clause (iii)(B)
shall be determined in the sole discretion of the Securities Administrator, and the Securities Administrator shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

 (iii) The Securities Administrator, on behalf of the Trustee, shall make available, upon written request from
the Trustee, all information necessary to compute any tax imposed 
  

	 	(A)	as a result of the Transfer of an Ownership Interest in a Residual Certificate to any Person who is a Disqualified Organization, including the information regarding “excess
inclusions” of such Residual Certificates required to be provided to the Internal Revenue Service and certain Persons as described in Treasury Regulations Sections 1.860D-1(b)(5) and 1.860E-2(a)(5), and 

  

	 	(B)	as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organization described in Section 1381 of the
Code that holds an Ownership Interest in a Residual Certificate having as among its record holders at any time any Person who is a Disqualified Organization. Reasonable compensation for providing such information may be required by the Securities
Administrator from such Person. 

  

 154 

 (iv) The provisions of this Section 6.02(g) set forth prior to this clause
(v) may be modified, added to or eliminated, provided that there shall have been delivered to the Trustee the following: 
  

	 	(A)	Written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its
then-current ratings, if any, of the Class A Certificates and Mezzanine Certificates below the lower of the then-current rating or the rating assigned to such Certificates as of the Closing Date by such Rating Agency; and

  

	 	(B)	a certificate of the Securities Administrator stating that the Securities Administrator has received an Opinion of Counsel, in form and substance satisfactory to the Securities
Administrator, to the effect that such modification, addition to or absence of such provisions will not cause any REMIC created hereunder to cease to qualify as a REMIC and will not cause (x) any REMIC created hereunder to be subject to an
entity-level tax caused by the Transfer of any Residual Certificate to a Person that is a Disqualified Organization or (y) a Certificateholder or another Person to be subject to a REMIC-related tax caused by the Transfer of a Residual
Certificate to a Person that is not a Permitted Transferee. 

 (h) No service charge to the Certificateholders shall be made
for any transfer or exchange of Certificates, but the Securities Administrator may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

 (i) All Certificates surrendered for transfer and exchange shall be canceled and destroyed by the Securities Administrator in accordance
with its customary procedures. 
 Section 6.03 Mutilated, Destroyed, Lost or Stolen Certificates. 
 If (i) any mutilated Certificate is surrendered to the Securities Administrator or the Certificate Registrar, or the Securities Administrator or the
Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and of the ownership thereof, and (ii) there is delivered to Securities Administrator or the Certificate Registrar such security or
indemnity as may be required by it to save it harmless, then, in the absence of actual knowledge by the Securities Administrator or the Certificate Registrar that such Certificate has been acquired by a protected purchaser, the Securities
Administrator, shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same Class and of like denomination and Percentage Interest. Upon the issuance
of any new Certificate under this Section, the Securities Administrator or the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Securities Administrator or the Certificate Registrar) connected therewith. Any replacement Certificate issued pursuant to this Section shall constitute complete and indefeasible 

  

 155 

 
evidence of ownership in the applicable REMIC created hereunder, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be
found at any time. 
 Section 6.04 Persons Deemed Owners. 
 The Depositor, the Servicer, the Trustee, the Master Servicer, the Securities Administrator, the Certificate Registrar and any agent of any of them may
treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.01 and for all other purposes whatsoever, and none of the Depositor, the Servicer,
the Trustee, the Master Servicer, the Securities Administrator, the Certificate Registrar or any agent of any of them shall be affected by notice to the contrary. 
 Section 6.05 Certain Available Information. 
 On or prior to the date of the first sale of any Class
CE Certificate, Class P Certificate or Residual Certificate to an Independent third party, the Depositor shall provide to the Securities Administrator ten copies of any private placement memorandum or other disclosure document used by the Depositor

the Depositor promptly shall inform the Securities Administrator of such event and shall deliver to the Securities Administrator ten copies of the private placement memorandum or disclosure document, as revised, amended or supplemented. The

 ARTICLE VII 
 THE DEPOSITOR, THE SERVICER AND THE MASTER SERVICER 
 Section 7.01 Liability of the Depositor, the
Servicer and the Master Servicer. 
 The Depositor, the Servicer and the Master Servicer each shall be liable in accordance herewith only
to the extent of the obligations specifically imposed by this Agreement upon them in their respective capacities as Depositor, the Servicer and Master Servicer and undertaken hereunder by the Depositor, the Servicer and the Master Servicer herein.

 Section 7.02 Merger or Consolidation of the Depositor, the Servicer or the Master Servicer. 
 Subject to the following paragraph, the Depositor will keep in full effect its existence, rights and franchises as a corporation under the laws of the
jurisdiction of its incorporation. Subject to the following paragraph, the Servicer will keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation. Subject to the following
paragraph, the Master Servicer will keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its formation. The Depositor, the Servicer and the Master Servicer each will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans and to
perform its respective duties under this Agreement. 
 The Depositor, the Servicer or the Master Servicer may be merged or consolidated with
or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor, the Servicer or the Master Servicer shall be a party, or any Person
succeeding to the business of the Depositor, the Servicer or the Master Servicer, shall be the successor of the Depositor, the Servicer or the Master Servicer, as the case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that any successor of the Servicer or the Master Servicer shall meet the eligibility requirements set forth in clauses
(i) and (iii) of the last paragraph of Section 8.02(a) or Section 7.06, as applicable. 
 Section 7.03 Limitation on
Liability of the Depositor, the Servicer, the Master Servicer and Others. 
 None of the Depositor, the Servicer, the Securities
Administrator, the Master Servicer or any of the directors, officers, employees or agents of the Depositor, the Servicer or the Master Servicer shall be under any liability to the Trust Fund or the Certificateholders for any action taken or for
refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Servicer, the Securities Administrator, the Master
Servicer or any such person against any breach of warranties, representations or covenants made herein or against any specific liability imposed on any such Person pursuant hereto or against any liability which would otherwise be imposed 

  

 157 

 
by reason of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties
hereunder. The Depositor, the Servicer, the Securities Administrator, the Master Servicer and any director, officer, employee or agent of the Depositor, the Servicer, the Securities Administrator and the Master Servicer may rely in good faith on any
document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Servicer, the Securities Administrator, the Master Servicer and any director, officer,
employee or agent of the Depositor, the Servicer, the Securities Administrator or the Master Servicer shall be indemnified and held harmless by the Trust Fund against any loss, liability or expense incurred in connection with any legal action
relating to this Agreement, the Certificates or the Credit Risk Management Agreement or any loss, liability or expense incurred other than by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by
reason of reckless disregard of obligations and duties hereunder. None of the Depositor, the Servicer, the Securities Administrator or the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action unless such
action is related to its respective duties under this Agreement and, in its opinion, does not involve it in any expense or liability; provided, however, that each of the Depositor, the Servicer, the Securities Administrator and the Master
Servicer may in its discretion undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event,
the legal expenses and costs of such action and any liability resulting therefrom (except any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of
reckless disregard of obligations and duties hereunder) shall be expenses, costs and liabilities of the Trust Fund, and the Depositor, the Servicer, the Securities Administrator and the Master Servicer shall be entitled to be reimbursed therefor
from the Collection Account or the Distribution Account as and to the extent provided in Article III and Article IV, any such right of reimbursement being prior to the rights of the Certificateholders to receive any amount in the Collection Account
and the Distribution Account. 
 Notwithstanding anything to the contrary contained herein, the Servicer shall not be liable for any actions
or inactions prior to the Cut-off Date of any prior servicer of the Mortgage Loans and the Master Servicer shall not be liable for any action or inaction of the Servicer, except to the extent expressly provided herein, or the Credit Risk Manager.

 Section 7.04 Limitation on Resignation of the Servicer. 
 (a) The Servicer shall neither assign all or substantially all of its rights under this Agreement or the servicing hereunder nor delegate all or
substantially all of its duties hereunder nor sell or otherwise dispose of all or substantially all of its property or assets without, in each case, the prior written consent of the Master Servicer, which consent shall not be unreasonably withheld;
provided, that in each case, there must be delivered to the Trustee and the Master Servicer a letter from each Rating Agency to the effect that such transfer of servicing or sale or disposition of assets will not result in a qualification,
withdrawal or downgrade of the then-current rating of any of the Certificates. Notwithstanding the foregoing, the Servicer, without the consent of the Trustee or the Master Servicer, may retain third-party contractors to perform certain servicing
and loan administration functions, including without limitation hazard insurance administration, tax payment and administration, flood certification and administration, 

  

 158 

 
collection services and similar functions, provided, however, that the retention of such contractors by the Servicer shall not limit the obligation of
the Servicer to service the Mortgage Loans pursuant to the terms and conditions of this Agreement. The Servicer shall not resign from the obligations and duties hereby imposed on it except by consent of the Master Servicer or upon determination that
its duties hereunder are no longer permissible under applicable law. Any such determination pursuant to the preceding sentence permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect obtained at the
expense of the Servicer and delivered to the Trustee and the Rating Agencies. No resignation of the Servicer shall become effective until the Master Servicer or a successor Servicer shall have assumed the Servicer’s responsibilities, duties,
liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement. 
 (b)
Except as expressly provided herein, the Servicer shall not assign or transfer all or substantially all of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person
to perform all or substantially all of the duties, covenants or obligations to be performed by the Servicer hereunder. The foregoing prohibition on assignment shall not prohibit the Servicer from designating a Sub-Servicer as payee of any
indemnification amount payable to the Servicer hereunder; provided, however, that as provided in Section 3.02, no Sub-Servicer shall be a third-party beneficiary hereunder and the parties hereto shall not be required to recognize any
Sub-Servicer as an indemnitee under this Agreement. 
 Section 7.05 Limitation on Resignation of the Master Servicer. 
 The Master Servicer shall not resign from the obligations and duties hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination pursuant to the preceding sentence permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the Master
Servicer and delivered to the Trustee and the Rating Agencies. No resignation of the Master Servicer shall become effective until the Trustee or a successor Master Servicer shall have assumed the Master Servicer’s responsibilities, duties,
liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement. 
 Section 7.06 Assignment of Master Servicing. 
 The Master Servicer may sell and assign its rights and delegate its duties
and obligations in its entirety as Master Servicer under this Agreement; provided, however, that: (i) the purchaser or transferee accept in writing such assignment and delegation and assume the obligations of the Master Servicer
hereunder (a) shall have a net worth of not less than $15,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (b) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed
by the Trustee); and (c) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each
covenant and condition to be performed or observed by it as master servicer under this Agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer and each 

  

 159 

 
Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or
withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee; and (iii) the Master Servicer assigning and selling the master servicing shall deliver to
the Trustee an officer’s certificate and an Opinion of Independent counsel, each stating that all conditions precedent to such action under this Agreement have been completed and such action is permitted by and complies with the terms of this
Agreement. No such assignment or delegation shall affect any liability of the Master Servicer arising out of acts or omissions prior to the effective date thereof. 
 Section 7.07 Rights of the Depositor in Respect of the Servicer and the Master Servicer. 
 Each of
the Master Servicer and the Servicer shall afford (and any Sub-Servicing Agreement shall provide that each Sub-Servicer shall afford) the Depositor and the Trustee, upon reasonable notice, during normal business hours, access to all records
maintained by the Master Servicer or the Servicer (and any such Sub-Servicer) in respect of the Servicer’s rights and obligations hereunder and access to officers of the Master Servicer or the Servicer (and those of any such Sub-Servicer)
responsible for such obligations, and the Master Servicer shall have access to all records maintained by the Servicer and any Sub-Servicer. Upon request, each of the Master Servicer and the Servicer shall furnish to the Depositor and the Trustee its
(and any such Sub-Servicer’s) most recent financial statements and such other information relating to the Master Servicer’s or the Servicer’s capacity to perform its obligations under this Agreement as it possesses (and that any such
Sub-Servicer possesses). To the extent the Depositor and the Trustee are informed that such information is not otherwise available to the public, the Depositor and the Trustee shall not disseminate any information obtained pursuant to the preceding
two sentences without the Master Servicer’s or the Servicer’s written consent, except as required pursuant to this Agreement or to the extent that it is appropriate to do so (i) to its legal counsel, auditors, taxing authorities or
other governmental agencies and the Certificateholders, (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or decree of any court or governmental authority having jurisdiction over the Depositor and the Trustee or the
Trust Fund, and in any case, the Depositor or the Trustee, (iii) disclosure of any and all information that is or becomes publicly known, or information obtained by the Trustee from sources other than the Depositor, the Servicer or the Master
Servicer, (iv) disclosure as required pursuant to this Agreement or (v) disclosure of any and all information (A) in any preliminary or final offering circular, registration statement or contract or other document pertaining to the
transactions contemplated by the Agreement approved in advance by the Depositor, the Servicer or the Master Servicer or (B) to any affiliate, independent or internal auditor, agent, employee or attorney of the Trustee having a need to know the
same, provided that the Trustee advises such recipient of the confidential nature of the information being disclosed, shall use its best efforts to assure the confidentiality of any such disseminated non-public information. Nothing in this
Section 7.07 shall limit the obligation of the Servicer to comply with any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Servicer to provide access as provided in this Section 7.07 as
a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 7.07 shall require the Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course
of business. The Servicer shall not be required to make copies of or ship documents to any party unless provisions have been made for the reimbursement of the costs thereof. The Depositor 

  

 160 

 
may, but is not obligated to, enforce the obligations of the Master Servicer and the Servicer under this Agreement and may, but is not obligated to, perform,
or cause a designee to perform, any defaulted obligation of the Master Servicer or the Servicer under this Agreement or exercise the rights of the Master Servicer or the Servicer under this Agreement; provided that neither the Master Servicer
nor the Servicer shall be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the
Master Servicer or the Servicer and is not obligated to supervise the performance of the Master Servicer or the Servicer under this Agreement or otherwise. 
 Section 7.08 Duties of the Credit Risk Manager. 
 For and on behalf of the Depositor, the Credit Risk
Manager will provide reports and recommendations concerning certain delinquent and defaulted Mortgage Loans, the collection of any Prepayment Charges with respect to the Mortgage Loans, calculation and reporting of payments due under the Cap
Agreement and the Interest Rate Swap Agreement, and Trigger Events in accordance with the terms and conditions of the Credit Risk Management Agreement. Such reports and recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the Credit Risk Management Agreement, and the Credit Risk Manager shall look solely to the Servicer, the Securities Administrator and/or the Depositor for all information and data (including loss and delinquency information and
data) relating to the servicing of the related Mortgage Loans. The obligations of the parties under the Credit Risk Management Agreement will terminate upon the earlier of (i) the termination of the Trust, (ii) the termination of the
Servicer’s rights and obligations under this Agreement, (iii) the resignation of the Credit Risk Manager upon at least thirty (30) days advance notice and the appointment of a successor Credit Risk Manager by the Depositor or its
assign, (iv) the removal of the Credit Risk Manager for cause by the Depositor or its assign upon at least thirty (30) days advance notice and the appointment of a successor Credit Risk Manager by the Depositor or its assign, or
(v) the removal of the Credit Risk Manager without cause upon thirty (30) days advance notice by the Depositor or its assign upon the request of the transferor of a majority of the residual interests in the Trust and the appointment of a
successor Credit Risk Manager by the Depositor or its assign, in each case, pursuant to the terms and conditions set forth in the Credit Risk Management Agreement. Upon any termination of the Credit Risk Manager or the appointment of a successor
Credit Risk Manager, the Depositor shall give written notice thereof to the Servicer, the Master Servicer, the Trustee, and each Rating Agency. 
 Section 7.09 Limitation Upon Liability of the Credit Risk Manager. 
 Neither the Credit Risk Manager, nor any of its
directors, officers, employees, or agents shall be under any liability to the Trustee, the Trust Fund, the Certificateholders, or the Depositor for any action taken or for refraining from the taking of any action made in good faith pursuant to this
Agreement and the Credit Risk Management Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Credit Risk Manager or any such person against liability for any breach of a representation, warranty
or covenant made herein or in the Credit Risk Management Agreement or against liability that would otherwise be imposed by reason of gross negligence, willful malfeasance, fraud or bad faith in its performance of its duties hereunder or thereunder.
The Credit Risk Manager and any director, officer, employee, or 

  

 161 

 
agent of the Credit Risk Manager may rely in good faith on any document of any kind which, prima facie, is properly executed and submitted by any
Person respecting any matters arising hereunder or under the Credit Risk Management Agreement. The Credit Risk Manager and its directors, managers, members, officers, employees and agents shall be indemnified and held harmless by the Trust Fund
against any loss, liability, cost, claim or expense (including costs and expenses of litigation and of investigation, reasonable counsel fees, damages, judgments and amounts paid in settlement) arising out of or incurred in connection with this
Agreement or the Credit Risk Management Agreement, other than any such loss, liability, cost, claim or expense that was incurred in connection with claims against such party resulting primarily from (i) any breach of a representation, warranty
or covenant made herein or in the Credit Risk Management Agreement by the Credit Risk Manager, or (ii) bad faith, fraud, gross negligence or willful misconduct in the performance of obligations or duties hereunder or under the Credit Risk
Management Agreement by the Credit Risk Manager, or its gross negligent disregard of such obligations or duties.

 162 

 (iii) a decree or order of a court or agency or supervisory authority having jurisdiction
in the premises in an involuntary case under any present or future federal or state bankruptcy, insolvency or similar law or the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets

Trustee (in which case notice shall be provided by telecopy) or to the Servicer, the Depositor, the Trustee and by the Holders of Certificates entitled to at least 25% of the Voting Rights. 
 If a Servicer Event of Default described in clauses (i) through (vi) of this Section shall occur, then, and in each and every such case, so long as such
Servicer Event of Default shall not have been remedied, the Depositor or the Trustee may, and at the written direction of the Holders of Certificates entitled to at least 51% of Voting Rights, the Trustee shall, by notice in writing to the Servicer
(and to the Depositor if given by the Trustee or to the Trustee if given by the Depositor) with a copy to the Master Servicer and each Rating Agency, terminate all of the rights and obligations of the Servicer in its capacity as the Servicer under
this Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. If a Servicer Event of Default described in clause (vii) hereof shall occur, the Trustee shall, by notice in writing to the Servicer, the

deliver, on behalf of and at the expense of the Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete
the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. The Servicer agrees promptly (and in any event no later than ten Business Days subsequent to such notice) to provide the Master Servicer with all
documents and records requested by it to enable it to assume the Servicer’s functions under this Agreement, and to cooperate with the Master Servicer in effecting the termination of the Servicer’s responsibilities and rights under this
Agreement, including, without limitation, the transfer within one Business Day to the Master Servicer for administration by it of all cash amounts which at the time shall be or should have been credited by the Servicer to the Collection Account held
by or on behalf of the Servicer or thereafter be received with respect to the Mortgage Loans or any REO Property (provided, however, that the Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this
Agreement on or prior to the date of such termination, whether in respect of P&I Advances, Servicing Advances, accrued and unpaid Servicing Fees or otherwise, and shall continue to be entitled to the benefits of Section 7.03,
notwithstanding any such termination, with respect to events occurring prior to such termination). For purposes of this Section 8.01(a), the Trustee shall not be deemed to have knowledge of a Servicer Event of Default unless a Responsible
Officer of the Trustee assigned to and working in the Trustee’s Corporate Trust Office has actual knowledge thereof or unless written notice of any event which is in fact such a Servicer Event of Default is received by the Trustee at its
Corporate Trust Office and such notice references the Certificates, the Trust or this Agreement. The Trustee shall promptly notify the Master Servicer and the Rating Agencies of the occurrence of a Servicer Event of Default of which it has knowledge
as provided above. 
 The Master Servicer shall be entitled to be reimbursed by the Servicer (or from amounts on deposit in the Distribution
Account if the Servicer is unable to fulfill its obligations hereunder) for all reasonable out-of-pocket or third party costs associated with the transfer of servicing from the predecessor Servicer (or if the predecessor Servicer is the Master
Servicer, from the Servicer immediately preceding the Master Servicer), including without limitation, any reasonable out-of-pocket or third party costs or expenses associated with the complete transfer of all servicing data and the completion,
correction or manipulation of such servicing data as may be required by the Master Servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the Master Servicer to service the Mortgage Loans properly and
effectively, upon presentation of reasonable documentation of such costs and expenses. 
 (b) “Master Servicer Event of Default,”
wherever used herein, means any one of the following events: 
 (i) any failure on the part of the Master Servicer duly to
observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer contained in this Agreement, or the breach by the Master Servicer of any representation and warranty contained in
Section 2.04, which continues unremedied for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Depositor or the 

  

 164 

 
Trustee or to the Master Servicer, the Depositor and the Trustee by the Holders of Certificates entitled to at least 25% of the Voting Rights; or 

(ii) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under
any present or future federal or state bankruptcy, insolvency or similar law or the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceeding, or for
the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 90 days; or 
 (iii) the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of
debt, marshalling of assets and liabilities or similar proceedings of or relating to it or of or relating to all or substantially all of its property; or 
 (iv) the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment
for the benefit of its creditors, or voluntarily suspend payment of its obligations. 
 If a Master Servicer Event of Default shall occur, then, and in each
and every such case, so long as such Master Servicer Event of Default shall not have been remedied, the Depositor or the Trustee may, and at the written direction of the Holders of Certificates entitled to at least 51% of Voting Rights, the Trustee
shall, by notice in writing to the Master Servicer (and to the Depositor if given by the Trustee or to the Trustee if given by the Depositor) with a copy to each Rating Agency, terminate all of the rights and obligations of the Master Servicer in
its capacity as Master Servicer under this Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the
Master Servicer under this Agreement, whether with respect to the Certificates (other than as a Holder of any Certificate) or the Mortgage Loans or otherwise including, without limitation, the compensation payable to the Master Servicer under this
Agreement, shall pass to and be vested in the Trustee pursuant to and under this Section, and, without limitation, the Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the
expense of the Master Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or otherwise. The Master Servicer agrees promptly (and in any event no later than ten Business Days subsequent to such notice) to provide the Trustee with all documents and
records requested by it to enable it to assume the Master Servicer’s functions under this Agreement, and to cooperate with the Trustee in effecting the termination of the Master Servicer’s responsibilities and rights under this Agreement
(provided, however, that the Master Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination and shall continue to be entitled to the benefits of
Section 7.03, notwithstanding any such termination, with respect to events occurring prior to such termination). For purposes of this Section 8.01(b), the Trustee shall not be deemed 

  

 165 

 
to have knowledge of a Master Servicer Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Trustee’s Corporate
Trust Office has actual knowledge thereof or unless written notice of any event which is in fact such a Master Servicer Event of Default is received by the Trustee and such notice references the Certificates, the Trust or this Agreement. The Trustee
shall promptly notify the Rating Agencies of the occurrence of a Master Servicer Event of Default of which it has knowledge as provided above. 
 To the extent that the costs and expenses of the Trustee related to the termination of the Master Servicer, appointment of a successor Master Servicer or the transfer and assumption of the master servicing by the Trustee (including, without
limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Master Servicer as a result of a Master Servicer Event of Default and (ii) all costs
and expenses associated with the complete transfer of the master servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor Master
Servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor Master Servicer to master service the Mortgage Loans in accordance with this Agreement) are not fully and timely reimbursed by the
terminated Master Servicer, the Trustee shall be entitled to reimbursement of such costs and expenses from the Distribution Account. Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is
unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of
not less than $15,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of a
master servicer, like the Master Servicer. 
 Neither the Trustee nor any other successor master servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the
failure of the Master Servicer to deliver or provide, or any delay of the Master Servicer in delivering or providing, any cash, information, documents or records to it. 
 Section 8.02 Master Servicer to Act; Appointment of Successor. 
 (a) On and after the time the
Servicer receives a notice of termination, the Master Servicer shall be the successor in all respects to the Servicer in its capacity as Servicer under this Agreement and the transactions set forth or provided for herein, and all the
responsibilities, duties and liabilities relating thereto and arising thereafter shall be assumed by the Master Servicer (except for any representations or warranties of the Servicer under this Agreement, the responsibilities, duties and liabilities
contained in Section 2.03 and the obligation to deposit amounts in respect of losses pursuant to Section 3.10(b)) by the terms and provisions hereof including, without limitation, the Servicer’s obligations to make P&I Advances
pursuant to Section 5.03; provided, however, that if the Master Servicer is prohibited by law or regulation from obligating itself to make advances regarding delinquent mortgage loans, then the Master Servicer shall not be obligated to
make P&I Advances pursuant to Section 5.03; and provided 

  

 166 

 
further, that any failure to perform such duties or responsibilities caused by the Servicer’s failure to provide information required by
Section 8.01 shall not be considered a default by the Master Servicer as successor to the Servicer hereunder; provided, however, that (1) it is understood and acknowledged by the parties hereto that there will be a period of
transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to the Master Servicer or any successor Servicer appointed in accordance with the following provisions and (2) any failure to perform such duties
or responsibilities caused by the Servicer’s failure to provide information required by Section 8.01 shall not be considered a default by the Master Servicer as successor to the Servicer hereunder. As compensation therefor, the Master
Servicer shall be entitled to the Servicing Fee and all funds relating to the Mortgage Loans to which the Servicer would have been entitled if it had continued to act hereunder. Notwithstanding the above and subject to the immediately following
paragraph, the Master Servicer may, if it shall be unwilling to so act, or shall, if it is unable to so act promptly appoint or petition a court of competent jurisdiction to appoint, a Person that satisfies the eligibility criteria set forth below
as the successor to the Servicer under this Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer under this Agreement. 
 Notwithstanding anything herein to the contrary, in no event shall the Trustee or the Master Servicer be liable for any Servicing Fee, or in the case of
the Trustee, any Master Servicer compensation, or for any differential in the amount of the Servicing Fee paid or Master Servicer compensation received hereunder and the amount necessary to induce any successor Servicer or Master Servicer to act as
successor Servicer or Master Servicer under this Agreement and the transactions set forth or provided for herein. 
 Any successor Servicer
appointed under this Agreement must (i) be an established mortgage loan servicing institution that is a Fannie Mae and Freddie Mac approved seller/servicer, (ii) be approved by each Rating Agency by a written confirmation from each Rating
Agency that the appointment of such successor Servicer would not result in the reduction or withdrawal of the then current ratings of any outstanding Class of Certificates, (iii) have a net worth of not less than $15,000,000 and
(iv) assume all the responsibilities, duties or liabilities of the Servicer (other than liabilities of the Servicer hereunder incurred prior to termination of the Servicer under Section 8.01 herein) under this Agreement as if originally
named as a party to this Agreement. 
 (b) (A) All servicing transfer costs (including, without limitation, servicing transfer costs of the
type described in Section 8.02(a) and incurred by the Trustee, the Master Servicer and any successor Servicer under paragraph (b)(2) below) shall be paid by the terminated Servicer upon presentation of reasonable documentation of such costs,
and if such predecessor or initial Servicer, as applicable, defaults in its obligation to pay such costs, the successor Servicer, the Master Servicer and the Trustee shall be entitled to reimbursement therefor from the assets of the Trust Fund.

 (B) No appointment of a successor to the Servicer under this Agreement shall be effective until the assumption by the
successor of all of the Servicer’s responsibilities, duties and liabilities hereunder. In connection with such appointment and assumption described herein, the Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; 

  

 167 

 
provided, however, that no such compensation shall be in excess of that permitted the Servicer as such hereunder. The Depositor, the Trustee and such
successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Pending appointment of a successor to the Servicer under this Agreement, the Master Servicer shall act in such capacity as
hereinabove provided. 
 Section 8.03 Notification to Certificateholders. 
 (a) Upon any termination of the Servicer or the Master Servicer pursuant to Section 8.01(a) or (b) or any appointment of a successor to the
Servicer or the Master Servicer pursuant to Section 8.02, the Trustee shall give prompt written notice thereof to the Certificateholders at their respective addresses appearing in the Certificate Register. 
 (b) Not later than the later of 60 days after the occurrence of any event, which constitutes or which, with notice or lapse of time or both, would
constitute a Servicer Event of Default or a Master Servicer Event of Default or five days after a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to all Holders of Certificates
notice of each such occurrence, unless such default or Servicer Event of Default or Master Servicer Event of Default shall have been cured or waived. 
 Section 8.04 Waiver of Servicer Events of Default. 
 The Holders representing at least 66% of the
Voting Rights evidenced by all Classes of Certificates affected by any default, Servicer Event of Default or Master Servicer Event of Default hereunder may waive such default, Servicer Event of Default or Master Servicer Event of Default;
provided, however, that a Servicer Event of Default under clause (i) or (vii) of Section 8.01(a) may be waived only by all of the Holders of the Regular Certificates. Upon any such waiver of a default, Servicer Event of Default
or Master Servicer Event of Default, such default, Servicer Event of Default or Master Servicer Event of Default shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. No such waiver shall extend to any
subsequent or other default, Servicer Event of Default or Master Servicer Event of Default or impair any right consequent thereon except to the extent expressly so waived. 
 ARTICLE IX 
 CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR 
 Section 9.01 Duties of Trustee and Securities Administrator. 
 The Trustee, prior to the occurrence of a Servicer Event of Default or a Master Servicer Event of Default and after the curing or waiver of all Master Servicer Events of Default and all Servicer Events of Default
which may have occurred, and the Securities Administrator each undertake to perform such duties and only such duties as are specifically set forth in this Agreement as duties of the Trustee and the Securities Administrator, respectively. During the
continuance of a Master Servicer Event of Default or a Servicer Event of Default, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in its exercise as a prudent person
would exercise or use under the 

  

 168 

 
circumstances in the conduct of such person’s own affairs. Any permissive right of the Trustee enumerated in this Agreement shall not be construed as a
duty. 
 Each of the Trustee and the Securities Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to it, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in a material manner, the Trustee or the Securities Administrator, as the case may be, shall take such action as it deems appropriate to have the instrument corrected, and
if the instrument is not corrected to its satisfaction, the Securities Administrator will provide notice to the Trustee thereof and the Trustee will provide notice to the Certificateholders. 
 The Trustee shall promptly remit to the Servicer any complaint, claim, demand, notice or other document (collectively, the “Notices”) delivered
to the Trustee as a consequence of the assignment of any Mortgage Loan hereunder and relating to the servicing of the Mortgage Loans; provided than any such notice (i) is delivered to the Trustee at its Corporate Trust Office,
(ii) contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property. The Trustee shall have no duty hereunder with respect to any Notice it may receive
or which may be alleged to have been delivered to or served upon it unless such Notice is delivered to it or served upon it at its Corporate Trust Office and such Notice contains the information required pursuant to clause (ii) of the preceding
sentence. 
 No provision of this Agreement shall be construed to relieve the Trustee or the Securities Administrator from liability for its
own negligent action, its own negligent failure to act or its own misconduct; provided, however, that: 
 (i) Prior to
the occurrence of a Master Servicer Event of Default, and after the curing or waiver of all such Master Servicer Events of Default which may have occurred with respect to the Trustee and at all times with respect to the Securities Administrator, the
duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, neither the Trustee nor the Securities Administrator shall be liable except for the performance of such duties and obligations as are
specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities
Administrator, respectively, the Trustee or the Securities Administrator, respectively, may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee or the Securities Administrator, respectively, that conform to the requirements of this Agreement; 
 (ii) Neither
the Trustee nor the Securities Administrator shall be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee or an officer or officers of the Securities Administrator, respectively, unless
it shall be proved that the Trustee or the Securities Administrator, respectively, was negligent in ascertaining the pertinent facts; and 
  

 169 

 (iii) Neither the Trustee nor the Securities Administrator shall be liable with respect
to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of Certificates entitled to at least 25% of the Voting Rights relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee or the Securities Administrator or exercising any trust or power conferred upon the Trustee or the Securities Administrator under this Agreement. 
 Section 9.02 Certain Matters Affecting Trustee and Securities Administrator. 
 (a) Except as otherwise provided in Section 9.01: 
 (i) Before taking any action or declining to take any action, as the case may be, under this Agreement, the Trustee and the Securities Administrator may request and rely upon and shall be protected in acting or
refraining from acting upon any resolution, Officers’ Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document reasonably
believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (ii) The Trustee and the
Securities Administrator may consult with counsel of its selection and any advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder
in good faith and in accordance with such advice or Opinion of Counsel; 
 (iii) Neither the Trustee nor the Securities
Administrator shall be under any obligation to exercise any of the trusts or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the
Certificateholders, pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee or the Securities Administrator, as the case may be, reasonable security or indemnity satisfactory to it against the
costs, expenses and liabilities which may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of a Master Servicer Event of Default (which has not been cured or waived),
to exercise such of the rights and powers vested in it by this Agreement, and to 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; 
 (iv) Neither the Trustee nor the Securities Administrator shall be liable for any action taken, suffered or
omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement; 
 (v) Prior to the occurrence of a Master Servicer Event of Default hereunder and after the curing or waiver of all Master Servicer Events of Default which may have occurred with respect to the Trustee and at all times
with respect to the Securities Administrator, neither the Trustee nor the Securities Administrator shall be bound to 

  

 170 

 
make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond or other paper or document, unless requested in writing to do so by the Holders of Certificates entitled to at least 25% of the Voting Rights; provided, however, that if the payment within a reasonable time to the
Trustee or the Securities Administrator of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee or the Securities Administrator, as applicable, not reasonably assured to
the Trustee or the Securities Administrator by such Certificateholders, the Trustee or the Securities Administrator, as applicable, may require reasonable indemnity satisfactory to it against such expense, or liability from such Certificateholders
as a condition to taking any such action; 
 (vi) The Trustee may execute any of the trusts or powers hereunder or perform any
duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
 (vii) The Trustee shall not be liable for any loss resulting from the investment of funds held in the Collection Account, or for any loss
resulting from the redemption or sale of any such investment as therein authorized; 
 (viii) The Trustee shall not be deemed
to have notice of any default, Master Servicer Event of Default or Servicer Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received
by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Certificates and this Agreement; and 
 (ix) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, each agent, custodian
and other Person employed to act hereunder. 
 (b) All rights of action under this Agreement or under any of the Certificates, enforceable by
the Trustee, may be enforced by it without the possession of any of the Certificates, or the production thereof at the trial or other proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee shall be brought in
its name for the benefit of all the Holders of such Certificates, subject to the provisions of this Agreement. 
 (c) The Securities
Administrator is hereby directed by the Depositor to execute the Interest Rate Swap Agreement and the Cap Agreement on behalf of the Trust Fund in the form presented to it by the Depositor and shall have no responsibility for the contents of the
Interest Rate Swap Agreement and the Cap Agreement, including, without limitation, the representations and warranties contained therein. Any funds payable by the Securities Administrator under the Interest Rate Swap Agreement and the Cap Agreement
at closing shall be paid by the Depositor. Notwithstanding anything to the contrary contained herein or in the Interest Rate Swap Agreement and the Cap Agreement, the Securities Administrator shall not be required to make 

  

 171 

 
any payments to the counterparty under the Interest Rate Swap Agreement and the Cap Agreement. The Securities Administrator hereby agrees to promptly provide
to the Credit Risk Manager any reset/payment advice or reset notification, or any other notice, report or statement received from the Swap Provider or the Cap Agreement Provider in connection with the Interest Rate Swap Agreement and the Cap
Agreement. 
 (d) None of the Securities Administrator, the Master Servicer, the Servicer, the Seller, the Depositor, the Custodian, the
Credit Risk Manager or the Trustee shall be responsible for the acts or omissions of the others, it being understood that this Agreement shall not be construed to render those partners joint venturers or agents of one another. 
 Section 9.03 Trustee and Securities Administrator not Liable for Certificates or Mortgage Loans. 
 The recitals contained herein and in the Certificates (other than the signature of the Securities Administrator, the authentication of the Securities
Administrator on the Certificates, the acknowledgments of the Trustee contained in Article II and the representations and warranties of the Trustee in Section 9.12) shall be taken as the statements of the Depositor and neither the Trustee nor
the Securities Administrator assumes any responsibility for their correctness. Neither the Trustee nor the Securities Administrator makes any representations or warranties as to the validity or sufficiency of this Agreement (other than as
specifically set forth in Section 9.12) or of the Certificates (other than the signature of the Securities Administrator and authentication of the Securities Administrator on the Certificates) or of any Mortgage Loan or related document. The
Trustee and the Securities Administrator shall not be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor or the
Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Servicer, other than with respect to the Securities Administrator any funds held by it or on behalf of the Trustee in accordance with
Section 3.23 and 3.24. 
 Section 9.04 Trustee and Securities Administrator May Own Certificates. 
 Each of the Trustee and the Securities Administrator in its individual capacity or any other capacity may become the owner or pledgee of Certificates and
may transact business with other interested parties and their Affiliates with the same rights it would have if it were not Trustee or the Securities Administrator. 
 Section 9.05 Fees and Expenses of Trustee and Securities Administrator. 
 The fees of the Trustee and
the Securities Administrator hereunder and of Wells Fargo as Custodian shall be paid in accordance with a side letter agreement with the Master Servicer and at the sole expense of the Master Servicer. In addition, the Trustee, the Securities
Administrator, the Custodian and any director, officer, employee or agent of the Trustee, the Securities Administrator and the Custodian shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable
attorney’s fees and expenses) incurred by the Trustee, the Custodian or the Securities Administrator arising out of or in connection with the acceptance or administration of its respective obligations and duties under this Agreement, 

  

 172 

 
including the Interest Rate Swap Agreement and the Cap Agreement and any and all other agreements related thereto, other than any loss, liability or expense
(i) for which the Trustee is indemnified by the Master Servicer or the Servicer, (ii) that constitutes a specific liability of the Trustee or the Securities Administrator pursuant to Section 11.01(g) or (iii) any loss, liability
or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of duties hereunder by the Trustee or the Securities Administrator or by reason of reckless disregard of obligations and duties hereunder. In no event
shall the Trustee or the Securities Administrator be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if it has been advised of the likelihood of such loss or
damage and regardless of the form of action. The Master Servicer agrees to indemnify the Trustee, from, and hold the Trustee harmless against, any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred by the
Trustee by reason of the Master Servicer’s willful misfeasance, bad faith or gross negligence in the performance of its duties under this Agreement or by reason of the Master Servicer’s reckless disregard of its obligations and duties
under this Agreement. In addition, the Seller agrees to indemnify the Trustee for, and to hold the Trustee harmless against, any loss, liability or expense arising out of, or in connection with, the provisions set forth in the last paragraph of
Section 2.01, including, without limitation, all costs, liabilities and expenses (including reasonable legal fees and expenses) of investigating and defending itself against any claim, action or proceeding, pending or threatened, relating to
the provisions of such paragraph. The indemnities in this Section 9.05 shall survive the termination or discharge of this Agreement and the resignation or removal of the Master Servicer, the Trustee, the Securities Administrator or the
Custodian. Any payment hereunder made by the Master Servicer to the Trustee shall be from the Master Servicer’s own funds, without reimbursement from REMIC I therefor. 
 Section 9.06 Eligibility Requirements for Trustee and Securities Administrator. 
 The Trustee and the Securities Administrator shall at all times be a corporation or an association (other than the Depositor, the Seller, the Master
Servicer or any Affiliate of the foregoing) organized and doing business under the laws of any state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least
$50,000,000 (or a member of a bank holding company whose capital and surplus is at least $50,000,000) and subject to supervision or examination by federal or state authority. If such corporation or association publishes reports of conditions 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 corporation or association shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so published. In case at any time the Trustee or the Securities Administrator, as applicable, shall cease to be eligible in accordance with the provisions of this Section, the
Trustee or the Securities Administrator, as applicable, shall resign immediately in the manner and with the effect specified in Section 9.07. 
 Section 9.07 Resignation and Removal of Trustee and Securities Administrator. 
 The Trustee and the Securities Administrator
may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Depositor, to the Master Servicer, to the Securities Administrator (or the Trustee, if the Securities Administrator resigns) 

  

 173 

 
and to the Certificateholders. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor trustee or successor securities
administrator by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee or Securities Administrator, as applicable, and to the successor trustee or successor securities administrator, as applicable. A copy of
such instrument shall be delivered to the Certificateholders, the Trustee, the Securities Administrator and the Master Servicer by the Depositor. If no successor trustee or successor securities administrator shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee or Securities Administrator, as the case may be, may, at the expense of the Trust Fund, petition any court of competent jurisdiction for the
appointment of a successor trustee, successor securities administrator, Trustee or Securities Administrator, as applicable. 
 If at any time
the Trustee or the Securities Administrator shall cease to be eligible in accordance with the provisions of Section 9.06 and shall fail to resign after written request therefor by the Depositor, or if at any time the Trustee or the Securities
Administrator shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or the Securities Administrator or of its property shall be appointed, or any public officer shall take charge or control of the
Trustee or the Securities Administrator or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor may remove the Trustee or the Securities Administrator, as applicable and appoint a successor
trustee or successor securities administrator, as applicable, by written instrument, in duplicate, which instrument shall be delivered to the Trustee or the Securities Administrator so removed and to the successor trustee or successor securities
administrator. A copy of such instrument shall be delivered to the Certificateholders, the Trustee, the Securities Administrator and the Master Servicer by the Depositor. 
 The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee or the Securities Administrator and appoint a successor trustee or successor securities administrator by
written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Depositor, one complete set to the Trustee or the Securities
Administrator so removed and one complete set to the successor so appointed. A copy of such instrument shall be delivered to the Certificateholders, the Trustee (in the case of the removal of the Securities Administrator), the Securities
Administrator (in the case of the removal of the Trustee) and the Master Servicer by the Depositor. 
 Any resignation or removal of the
Trustee or the Securities Administrator and appointment of a successor trustee or successor securities administrator pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor
trustee or successor securities administrator, as applicable, as provided in Section 8.08. Notwithstanding anything to the contrary contained herein, the Master Servicer and the Securities Administrator shall at all times be the same Person.

 Section 9.08 Successor Trustee or Securities Administrator. 
 Any successor trustee or successor securities administrator appointed as provided in Section 9.07 shall execute, acknowledge and deliver to the
Depositor and its predecessor trustee 

  

 174 

 
or predecessor securities administrator an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor
trustee or predecessor securities administrator shall become effective and such successor trustee or successor securities administrator without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally named as trustee or securities administrator herein. The predecessor trustee or predecessor securities administrator shall deliver to the successor trustee or successor
securities administrator all Mortgage Files and related documents and statements to the extent held by it hereunder, as well as all moneys, held by it hereunder, and the Depositor and the predecessor trustee or predecessor securities administrator
shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee or successor securities administrator all such rights, powers, duties and
obligations. 
 No successor trustee or successor securities administrator shall accept appointment as provided in this Section unless at the
time of such acceptance such successor trustee or successor securities administrator shall be eligible under the provisions of Section 8.06 and the appointment of such successor trustee or successor securities administrator shall not result in
a downgrading of any Class of Certificates by any Rating Agency, as evidenced by a letter from each Rating Agency. 
 Upon acceptance of
appointment by a successor trustee or successor securities administrator as provided in this Section, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the
Certificate Register. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee or successor securities administrator, the successor trustee or successor securities administrator shall cause
such notice to be-mailed at the expense of the Depositor. 
 Section 9.09 Merger or Consolidation of Trustee or Securities
Administrator. 
 Any corporation or association into which the Trustee or the Securities Administrator may be merged or converted or
with which it may be consolidated or any corporation or association resulting from any merger, conversion or consolidation to which the Trustee or the Securities Administrator shall be a party, or any corporation or association succeeding to the
business of the Trustee or the Securities Administrator shall be the successor of the Trustee or the Securities Administrator hereunder, provided such corporation or association shall be eligible under the provisions of Section 8.06, without
the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 
 Section 9.10 Appointment of Co-Trustee or Separate Trustee. 
 Notwithstanding any other provisions hereof, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any part of the REMIC I or property securing the same may at the time be located, the Trustee shall have the power and shall execute and deliver all instruments to appoint
one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of 

  

 175 

 
REMIC I, and to vest in such Person or Persons, in such capacity, and for the benefit of the Holders of the Certificates, such title to REMIC I, or any part
thereof, and, subject to the other provisions of this Section 9.10, such powers, duties, obligations, rights and trusts as the Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet
the terms of eligibility as a successor trustee under Section 9.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof. 
 In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 9.10 all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular
act or acts are to be performed by the Trustee (whether as Trustee hereunder or as successor to a defaulting Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations (including the holding of title to REMIC I or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee. 
 Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as
effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article IX. Each separate trustee and co-trustee, upon its acceptance of the trust
conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee, or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including
every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee. 
 Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent
not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties,
rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee or co-trustee. 
 Section 9.11 Appointment of Office or Agency. 
 The Certificates may be surrendered for registration of transfer or exchange at the Securities Administrator’s office located at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479, and presented for

 Section 9.12 Representations and Warranties. 
 The Trustee hereby represents and warrants to the Master Servicer, the Securities Administrator and the Depositor as applicable, as of the Closing Date,
that: 
 (i) It is a national banking association duly organized, validly existing and in good standing under the laws of the
United States, (ii) The execution and delivery of this Agreement by it, and the performance and compliance with the terms of this Agreement by it, will not violate its articles of association or bylaws or constitute a default (or an event
which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material agreement or other instrument to which it is a party or which is applicable to it or any of its assets. 
 (ii) It has the full power and authority 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. (iv) This Agreement, assuming due authorization, execution and delivery by the other parties hereto, constitutes a valid, legal and
binding obligation of it, enforceable against it in accordance with the terms hereof, subject to (A) applicable bankruptcy, insolvency, receivership, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights
generally, and (B) general principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law. 
 (iii) It is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms of this Agreement will not constitute a violation of, any law, any order or decree of
any court or arbiter, or any order, regulation or demand of any federal, state or local governmental or regulatory authority, which violation, in its good faith and reasonable judgment, is likely to affect materially and adversely either the ability
of it to perform its obligations under this Agreement or its financial condition. 
 (iv) No litigation is pending or, to the
best of its knowledge, threatened against it, which would prohibit it from entering into this Agreement or, in its good faith reasonable judgment, is likely to materially and adversely affect either the ability of it to perform its obligations under
this Agreement or its financial condition.

payments in respect of the REMIC I Regular Interests, REMIC II Regular Interests or the Classes of Certificates as hereinafter set forth) shall terminate upon payment to the Certificateholders and 

  

 177 

 
the deposit of all amounts held by or on behalf of the Trustee and required hereunder to be so paid or deposited on the Distribution Date coinciding with or
following the earlier to occur of (i) the purchase by the Servicer (as described below) all Mortgage Loans and each REO Property remaining in REMIC I and (ii) the final payment or other liquidation (or any advance with respect thereto) of
the last Mortgage Loan or REO Property remaining in REMIC I; provided, however, that in no event shall the trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P.
Kennedy, the late ambassador of the United States to the Court of St. James, living on the date hereof. 
 (b) The Servicer may, at its
option (the party exercising such right the “Terminator”), terminate this Agreement on any Distribution Date on which the aggregate of the Stated Principal Balances of the Mortgage Loans (after giving effect to scheduled payments of
principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) on such date is equal to or less than 10% of the aggregate Stated Principal
Balance of the Mortgage Loans on the Cut-off Date, by purchasing, on such Distribution Date, all of the outstanding Mortgage Loans and REO Properties at a price equal to the fair market value of the Mortgage Loans and REO Properties (as determined
by the Terminator and, to the extent that the Class A Certificates or a Class of Mezzanine Certificates will not receive all amounts owed to it as a result of the termination, the Securities Administrator, as of the close of business on the
third Business Day next preceding the date upon which notice of any such termination is furnished to the related Certificateholders pursuant to Section 10.01(c)), plus accrued and unpaid interest thereon at the weighted average of the Mortgage
Rates through the end of the Due Period preceding the final Distribution Date plus unreimbursed Servicing Advances, P&I Advances, any unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties, any accrued unpaid Net WAC Rate
Carryover Amount, any previously unpaid Allocated Realized Loss Amounts and any Swap Termination Payment to the Swap Provider then remaining unpaid or which is due to the exercise of such option, and any unreimbursed expenses due to any party to
this Agreement (the “Termination Price”). In connection with any such purchase pursuant to the preceding paragraph, the Servicer shall deposit in the Distribution Account all amounts then on deposit in the Collection Account, which deposit
shall be deemed to have occurred immediately preceding such purchase. 
 Any such purchase shall be accomplished by deposit into the
Distribution Account on the Determination Date before such Distribution Date of the Termination Price. 
 (c) Notice of any termination,
specifying the Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Securities Administrator for payment of the final distribution and
cancellation, shall be given promptly by the Securities Administrator upon the Securities Administrator receiving notice of such date from the Servicer, by letter to the Certificateholders mailed not earlier than the 15th day and not later than the 25th day of the month next preceding the month of such final distribution specifying (1) the Distribution Date upon which final distribution of the Certificates will be made upon presentation and
surrender of such Certificates at the office or agency of the Securities Administrator therein designated, (2) the amount of any such final distribution and (3) that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the Certificates at the office or agency of the Securities Administrator therein specified. 
  

 178 

 (d) Upon presentation and surrender of the Certificates, the Securities Administrator shall cause to be
distributed to the Holders of the Certificates on the Distribution Date for such final distribution, in proportion to the Percentage Interests of their respective Class and to the extent that funds are available for such purpose, an amount equal to
the amount required to be distributed to such Holders in accordance with the provisions of Section 5.01 for such Distribution Date. 
 (e) In the event that all Certificateholders shall not surrender their Certificates for final payment and cancellation on or before such final Distribution Date, the Securities Administrator shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to Certificateholders to be withdrawn therefrom and credited to the remaining Certificateholders by depositing such funds in a separate Servicing Account for the benefit of such
Certificateholders, and the Master Servicer (if the Servicer has exercised its right to purchase the Mortgage Loans) or the Securities Administrator (in any other case) shall give a second written notice to the remaining Certificateholders, to
surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within nine months after the second notice all the Certificates shall not have been surrendered for cancellation, the Residual
Certificateholder shall be entitled to all unclaimed funds and other assets which remain subject hereto, and the Securities Administrator upon transfer of such funds shall be discharged of any responsibility for such funds, and the
Certificateholders shall look to the Residual Certificateholder for payment. 
 Section 10.02 Additional Termination Requirements.

 (a) In the event that the Servicer purchases all the Mortgage Loans and each REO Property or the final payment on or other liquidation of
the last Mortgage Loan or REO Property remaining in REMIC I pursuant to Section 10.01, the Trust Fund shall be terminated in accordance with the following additional requirements: 
 (i) The Securities Administrator shall specify the first day in the 90-day liquidation period in a statement attached to each Trust
REMIC’s final Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy all requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of
Counsel obtained by and at the expense of the Servicer; 
 (ii) During such 90-day liquidation period and, at or prior to the
time of making of the final payment on the Certificates, the Trustee shall sell all of the assets of REMIC I to the Servicer for cash; and 
 (iii) At the time of the making of the final payment on the Certificates, the Securities Administrator shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates
all cash on hand in the Trust Fund (other than cash retained to meet claims), and the Trust Fund shall terminate at that time. 
 (b) At the
expense of the Servicer (or, if the Trust Fund is being terminated as a result of the occurrence of the event described in clause (ii) of the first paragraph of Section 10.01, at the expense of the Trust Fund), the Servicer shall prepare
or cause to be prepared the documentation required in connection with the adoption of a plan of liquidation of each Trust REMIC pursuant to this Section 10.02. 
  

 179 

 (c) By their acceptance of Certificates, the Holders thereof hereby agree to authorize the Securities
Administrator to specify the 90-day liquidation period for each Trust REMIC, which authorization shall be binding upon all successor Certificateholders. 
 ARTICLE XI 
 REMIC PROVISIONS 
 Section 11.01 REMIC Administration. 
 (a) REMIC elections as set forth in the Preliminary Statement shall be made by the Trustee on Form 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the
Certificates are issued. The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement. 
 (b) The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 860G(a)(9) of the Code. 
 (c) The Securities Administrator shall pay any and all tax related expenses (not including taxes) of each REMIC, including but not limited to any professional fees or expenses related to audits or any administrative
or judicial proceedings with respect to each REMIC that involve the Internal Revenue Service or state tax authorities, but only to the extent that (i) such expenses are ordinary or routine expenses, but not including expenses of a routine audit
or expenses of litigation (except as described in (ii)); or (ii) such expenses or liabilities (including taxes and penalties) are attributable to the negligence or willful misconduct of the Securities Administrator in fulfilling its duties
hereunder. The Securities Administrator shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Collection Account. 
 (d) The Securities Administrator shall prepare and file, and the Trustee shall sign all of the Tax Returns in respect of each REMIC created hereunder. The expenses of preparing and filing such returns shall be borne
by the Securities Administrator without any right of reimbursement thereof. 
 (e) The Holder of the Residual Certificate at any time holding
the largest Percentage Interest thereof shall be the “tax matters person” as defined in the REMIC Provisions (the “Tax Matters Person”) with respect to the related REMIC and shall act as Tax Matters Person for each REMIC. The
Securities Administrator, as agent for the Tax Matters Person, shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance
guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Securities Administrator, as agent for the Tax Matters Person,
shall provide (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to 

  

 180 

 
the transfer of a Residual Certificate to any disqualified person or organization and (ii) to the Certificateholders such information or reports as are
required by the Code or REMIC Provisions. The Securities Administrator, as agent for the Tax Matters Person, shall represent each REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any REMIC, enter into settlement agreements with any government taxing agency, extend any statute of limitations relating to any item of any REMIC and otherwise act on behalf
of any REMIC in relation to any tax matter involving the Trust. 
 (f) The Securities Administrator and the Holders of Certificates shall
take any action or cause the REMIC to take any action necessary to create or maintain the status of each REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, the
Securities Administrator nor the Holder of any Residual Certificate shall take any action, cause any REMIC created hereunder to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or
not taken, as the case may be, could (i) endanger the status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon such REMIC (including but not limited to the tax on prohibited transactions as defined in Code
Section 860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Securities Administrator have received an Opinion of
Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. In addition, prior to taking any action with respect to any REMIC
created hereunder or the assets therein, or causing such REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate will consult with the Trustee and the Securities
Administrator, or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such
action as to which the Trustee or the Securities Administrator has advised it in writing that an Adverse REMIC Event could occur. 
 (g) Each
Holder of a Residual Certificate shall pay when due any and all taxes imposed on each REMIC created hereunder by federal or state governmental authorities. To the extent that such Trust taxes are not paid by a Residual Certificateholder, the
Securities Administrator shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in the REMICs or, if no such amounts are available, out of other amounts held in the
Distribution Account, and shall reduce amounts otherwise payable to Holders of regular interests in the related REMIC. Subject to the foregoing, in the event that a REMIC incurs a state or local tax, including franchise taxes, as a result of a
determination that such REMIC is domiciled in the State of California or any other state for state tax purposes by virtue of the location of the Servicer or any subservicer, the Servicer agrees to pay on behalf of such REMIC when due, any and all
state and local taxes imposed as a result of such a determination, in the event that the Holder of the related Residual Certificate fails to pay such taxes, if any, when imposed. 
 (h) The Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to each REMIC created hereunder on a
calendar year and on an accrual basis. 
  

 181 

 (i) No additional contributions of assets shall be made to any REMIC created hereunder, except as
expressly provided in this Agreement with respect to eligible substitute mortgage loans. 
 (j) Neither the Trustee nor the Securities
Administrator shall enter into any arrangement by which any REMIC created hereunder will receive a fee or other compensation for services. 
 (k) The Securities Administrator will apply for an Employee Identification Number from the Internal Revenue Service via a Form SS-4 or other acceptable method for all tax entities and shall complete the Form 8811. 
 Section 11.02 Prohibited Transactions and Activities. 
 Neither the Depositor, the Servicer, the Master Servicer, the Securities Administrator nor the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a disposition pursuant to
(i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination of any REMIC created hereunder pursuant to Article X of this Agreement, (iv) a substitution pursuant to Article II of this
Agreement or (v) a repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Distribution Account for gain, nor accept any contributions to either
REMIC after the Closing Date, unless it has received an Opinion of Counsel (at the expense of the party causing such sale, disposition, or substitution) that such disposition, acquisition, substitution, or acceptance will not (a) affect
adversely the status of any REMIC created hereunder as a REMIC or of the interests therein other than the Residual Certificates as the regular interests therein, (b) affect the distribution of interest or principal on the Certificates,
(c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement) or (d) cause any REMIC created hereunder to be subject to a tax on prohibited transactions or
prohibited contributions pursuant to the REMIC Provisions. 
 Section 11.03 Indemnification with Respect to Certain Taxes and Loss of
REMIC Status. 
 (a) The Trustee agrees to be liable for any taxes and costs incurred by the Trust Fund, the Depositor, the Master
Servicer, the Securities Administrator or the Servicer including, without limitation, any reasonable attorneys fees imposed on or incurred by the Trust Fund, the Depositor, the Master Servicer, the Securities Administrator or the Servicer as a
result of the Trustee’s failure to perform its covenants set forth in this Article XI in accordance with the standard of care of the Trustee set forth in this Agreement. 
 (b) The Servicer agrees to indemnify the Trust Fund, the Depositor, the Master Servicer, the Securities Administrator and the Trustee for any taxes and
costs including any reasonable attorneys’ fees imposed on or incurred by the Trust Fund, the Depositor, the Master Servicer, the Securities Administrator or the Trustee, as a result of the Servicer’s failure to perform its covenants set
forth in Article III in accordance with the standard of care of the Servicer set forth in this Agreement. 
  

 182 

 (c) The Master Servicer agrees to indemnify the Trust Fund, the Depositor, the Servicer and the Trustee
for any taxes and costs including any reasonable attorneys’ fees imposed on or incurred by the Trust Fund, the Depositor, the Servicer or the Trustee, as a result of the Master Servicer’s failure to perform its covenants set forth in
Article IV in accordance with the standard of care of the Master Servicer set forth in this Agreement. 
 (d) The Securities Administrator
agrees to be liable for any taxes and costs incurred by the Trust Fund, the Depositor or the Trustee including any reasonable attorneys fees imposed on or incurred by the Trust Fund, the Depositor, the Servicer or the Trustee as a result of the
Securities Administrator’s failure to perform its covenants set forth in this Article XI in accordance with the standard of care of the Securities Administrator set forth in this Agreement.

 MISCELLANEOUS
PROVISIONS 
 Section 12.01 Amendment. 
 This Agreement may be amended from time to time by the Depositor, the Servicer, the Master Servicer, the Securities Administrator and the Trustee, but without the consent of any of the Certificateholders, (i) to
cure any ambiguity or defect, (ii) to correct, modify or supplement any provisions herein (including to give effect to the expectations of Certificateholders), or (iii) to make any other provisions with respect to matters or questions
arising under this Agreement which shall not be inconsistent with the provisions of this Agreement, provided that such action shall not, as evidenced by an Opinion of Counsel delivered to the Trustee, adversely affect in any material respect
the interests of any Certificateholder; provided that any such amendment shall be deemed not to adversely affect in any material respect the interests of the Certificateholders and no such Opinion of Counsel shall be required if the Person
requesting such amendment obtains a letter from each Rating Agency stating that such amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates. No amendment shall be deemed to adversely
affect in any material respect the interests of any Certificateholder who shall have consented thereto, and no Opinion of Counsel shall be required to address the effect of any such amendment on any such consenting Certificateholder. Notwithstanding
any of the other provisions of this Section 12.01, none of the Depositor, the Servicer, the Master Servicer, the Securities Administrator or the Trustee shall enter into any amendment of this Agreement that could have an adverse effect on the
Swap Provider without the prior written consent of the Swap Provider. 
 This Agreement may also be amended from time to time by the
Depositor, the Servicer, the Master Servicer, the Securities Administrator and the Trustee with the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the
timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) as evidenced by an Opinion of Counsel delivered to the Trustee, adversely affect
in any material respect the interests of the Holders of 

  

 183 

 
any Class of Certificates in a manner, other than as described in (i), without a letter from each Rating Agency stating that such amendment would not result
in the downgrading or withdrawal of the respective ratings then assigned to the Certificates, or (iii) modify the consents required by the immediately preceding clauses (i) and (ii) without the consent of the Holders of all
Certificates then outstanding. Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this Section 12.01, Certificates registered in the name of the Depositor or the Servicer or
any Affiliate thereof shall be entitled to Voting Rights with respect to matters affecting such Certificates. Without limiting the generality of the foregoing, any amendment to this Agreement required in connection with the compliance with or the
clarification of any reporting obligations described in Section 5.09 hereof shall not require the consent of any Certificateholder and without the need for any Opinion of Counsel or Rating Agency confirmation. 
 Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel to the effect that such amendment will not result in the imposition of any tax on any Trust REMIC pursuant to the REMIC Provisions or cause any Trust REMIC to fail to qualify as a REMIC at any time that any
Certificates are outstanding, that such amendment is authorized or permitted by this Agreement and that all conditions precedent thereto have been satisfied. 
 Promptly after the execution of any such amendment the Trustee shall furnish a copy of such amendment to each Certificateholder. It shall not be necessary for the consent of Certificateholders under this
Section 12.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution
thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe. The cost of any Opinion of Counsel to be delivered pursuant to this Section 12.01 shall be borne by the Person seeking the related
amendment, but in no event shall such Opinion of Counsel be an expense of the Trustee. The Trustee may, but shall not be obligated to enter into any amendment pursuant to this Section that affects its rights, duties and immunities under this
Agreement or otherwise. 
 Section 12.02 Recordation of Agreement; Counterparts. 
 To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Depositor at the
expense of the Certificateholders, but only upon direction of the Trustee accompanied by an Opinion of Counsel (provided at the expense of the Certificateholder requesting recordation) to the effect that such recordation materially and beneficially
affects the interests of the Certificateholders. 
 For the purpose of facilitating the recordation of this Agreement as herein provided and
for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

 Section 12.03 Limitation on Rights of Certificateholders. 
 The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them. 
 No Certificateholder shall have any right to vote (except as expressly provided for herein) or in any
manner otherwise control the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of any of the Certificates, be construed so as to constitute the
Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Agreement pursuant to any provision
hereof. 
 No Certificateholder shall have any right by virtue of any provision of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of
Certificates entitled to at least 25% of the Voting Rights shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 15 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute
any such action, suit or proceeding. It is understood and intended, and expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner
whatsoever by virtue of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce
any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section, each and every Certificateholder and
the Trustee shall be entitled to such relief as can be given either at law or in equity.

12.08 Article and Section References. 
 All article and section references used in this Agreement, unless otherwise provided, are to
articles and sections in this Agreement. 
 Section 12.09 Grant of Security Interest. 
 It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Depositor to the Trustee, on behalf of the Trust and for
the benefit of the Certificateholders, be, and be construed as, a sale of the Mortgage Loans by the Depositor and not a pledge of the Mortgage Loans to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding
the aforementioned intent of the parties, the Mortgage Loans are held to be property of the Depositor, then, (a) it is the express intent of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the
Trustee, on behalf of the Trust and for the benefit of the Certificateholders, to secure a debt or other obligation of the Depositor and (b)(1) this Agreement shall also be deemed to be a security agreement within the meaning of 

  

 187 

 
Articles 8 and 9 of the Uniform Commercial Code as in effect from time to time in the State of New York; (2) the conveyance provided for in
Section 2.01 shall be deemed to be a grant by the Depositor to the Trustee, on behalf of the Trust and for the benefit of the Certificateholders, of a security interest in all of the Depositor’s right, title and interest in and to the
Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property,
including without limitation all amounts, other than investment earnings, from time to time held or invested in the Collection Account and the Distribution Account, whether in the form of cash, instruments, securities or other property; (3) the
obligations secured by such security agreement shall be deemed to be all of the Depositor’s obligations under this Agreement, including the obligation to provide to the Certificateholders the benefits of this Agreement relating to the Mortgage
Loans and the Trust Fund; and (4) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest under applicable law. Accordingly, the Depositor hereby grants to the Trustee, on behalf of the Trust and for the
benefit of the Certificateholders, a security interest in the Mortgage Loans and all other property described in clause (2) of the preceding sentence, for the purpose of securing to the Trustee the performance by the Depositor of the
obligations described in clause (3) of the preceding sentence. Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant to Section 2.01 to be a true, absolute and unconditional sale of the Mortgage Loans and assets
constituting the Trust Fund by the Depositor to the Trustee, on behalf of the Trust and for the benefit of the Certificateholders. 
 Section
12.10 Survival of Indemnification. Any and all indemnities to be provided by any party to this Agreement shall survive the termination and resignation of any party hereto and the termination of this Agreement. 
 Section 12.11 Third Party Beneficiary. The Swap Provider is an express third-party beneficiary of this Agreement, and shall have the right to
enforce the provisions of this Agreement.

2006-OPT2 
 This Certificate is one of a duly authorized issue of Certificates designated as SG Mortgage Securities Trust 2006-OPT2, Asset-Backed
Certificates, Series 2006-OPT2 (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust created by the Agreement. 
 The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account for payment hereunder and that the Securities Administrator is not
liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement. 
 This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits,
obligations and duties evidenced thereby, and the rights, duties and immunities of the Securities Administrator. 
 Pursuant to the terms of the Agreement, a
distribution will be made on the 25th day of each month or, if such 25th day is not a Business Day then the first Business Day following such Distribution Date (the “Distribution Date”), commencing on the first Distribution Date specified
on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement. 
 Distributions on this Certificate shall be made by check or money order mailed to the address of the person entitled thereto as it appears on the Certificate Register or by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the office or agency of the Securities Administrator specified in the notice to Certificateholders of such final
distribution. 
 No transfer of this Certificate or any interest herein shall be made to any Plan or Plan Investor. 
 The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Securities Administrator
and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Servicer, the Master Servicer, the Securities Administrator and the Trustee, if any and of Holders of the requisite percentage of the Percentage Interests
of each Class of Certificates affected by such amendment, as specified in the Agreement. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without
the consent of the Holders of any of the Certificates.

 As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is
registrable in the Certificate Register of the Securities Administrator upon surrender of this Certificate for registration of transfer at the office or agency maintained by the Securities Administrator accompanied by a written instrument of
transfer in form satisfactory to the Securities Administrator and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in
authorized denominations and evidencing the same aggregate Percentage Interest in the Trust will be issued to the designated transferee or transferees. 
 The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for
new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same. 
 No service charge will be made for any such registration of transfer or exchange, but the Securities Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith. 
 The Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Trustee, the Certificate Registrar, and any
agent of the Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Trustee or the Certificate Registrar may treat the Person, including a Depository, in whose name any Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Trustee or the Trust nor any agent of any of them shall be affected by notice to the contrary. 
 On any Distribution Date following the date at which the remaining aggregate Principal Balance of the Mortgage Loans is less than 10% of the aggregate Principal Balance
of the Mortgage Loans as of the Cut-off Date, the Servicer may purchase, in whole, from the Trust the Mortgage Loans at a purchase price determined as provided in the Agreement. In the event that no such optional termination occurs, the obligations
and responsibilities created by the Agreement will terminate upon notice to the Trustee upon the earliest of (i) the Distribution Date on which the Certificate Principal Balances of the Regular Certificates have been reduced to zero,
(ii) the final payment or other liquidation of the last Mortgage Loan in the Trust, (iii) the Distribution Date in October 2036. 
 Capitalized
terms used herein that are defined in the Agreement shall have the meanings ascribed to them in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

 This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits,
obligations and duties evidenced thereby, and the rights, duties and immunities of the Securities Administrator.

authorized denominations and evidencing the same aggregate Percentage Interest in the Trust will be issued to the designated transferee or transferees. 
 The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for
new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

Administrator and the Depositor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Act, which Opinion of Counsel shall not be obtained at the expense of the Securities Administrator or the Depositor; or there

 This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits,
obligations and duties evidenced thereby, and the rights, duties and immunities of the Securities Administrator. 
 Pursuant to the terms of the Agreement, a

authorized denominations and evidencing the same aggregate Percentage Interest in the Trust will be issued to the designated transferee or transferees. 
 The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for
new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same. 
 No service charge will be made for any such registration of transfer or exchange, but the Securities Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith. 
 The Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Trustee, the Certificate Registrar, and any

respect to the Certificates, any interest in the Certificates or any other similar security with, any person in any manner, or made any general solicitation by means of general advertising or in any other manner, or taken any other action, that

 PURSUANT TO SECTION 5.02(d) 
 SG
Mortgage Securities Trust 2006-OPT2, Asset-Backed Certificates Series 2006-OPT2 
  

			
	STATE OF______________)	 	
	)	 	ss.:
	COUNTY OF____________)	 	

 The undersigned, being first duly sworn, deposes and says as follows: 
 1. The undersigned is an officer of [                    ], the
proposed Transferee of an Ownership Interest in a Residual Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement dated as of December 1, 2006 (the “Agreement”), among SG Mortgage Securities,
LLC, as depositor (the “Depositor”), Option One Mortgage Corporation, as servicer (the “Servicer”), Wells Fargo Bank, N.A., as custodian, securities administrator and master servicer (the “Master Servicer”) and HSBC
Bank USA, National Association, as trustee (the “Trustee”). Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the
undersigned to make this affidavit on behalf of the Transferee for the benefit of the Depositor and the Trustee. 
 2. The Transferee is, as of the date
hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate for its own account. The Transferee has no knowledge that any such affidavit is false. 
 3. The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees;
(ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable
for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual
knowledge that the affidavit is false. 
 4. The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through
entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is not a Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not
be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is
false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in
Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.) 
  

 K-1 

 5. The Transferee has reviewed the provisions of Section 5.02(d) of the Agreement and understands the legal
consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly
agrees to be bound by and to abide by the provisions of Section 5.02(d) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included
herein shall render the Transfer to the Transferee contemplated hereby null and void. 
 6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its
Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a
certificate substantially in the form set forth as Exhibit L to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted
Transferee. 
 7. The Transferee has historically paid its debts as they have come due, intends to pay its debts as they come due in the future, and
understands that the taxes payable with respect to the Certificate may exceed the cash flow with respect thereto in some or all periods and intends to pay such taxes as they become due. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to the Certificate. 
 8. The Transferee’s taxpayer identification number
is __________________. 
 9. The Transferee is a U.S. Person as defined in Code Section 7701(a)(30). 
 10. The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of proposed Treasury regulations promulgated
pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or
collection of tax. 
 11. The Transferee will not cause income from the Certificate to be attributable to a foreign permanent establishment or fixed base,
within the meaning of an applicable income tax treaty, of the Transferee or any other U.S. person. 
 12. Check one of the following: 
 [_] The present value of the anticipated tax liabilities associated with holding the Certificate, as applicable, does not exceed the sum of: 
  

 K-2 

 (i) the present value of any consideration given to the Transferee to acquire such Certificate;

 (ii) the present value of the expected future distributions on such Certificate; and 
 (iii) the present value of the anticipated tax savings associated with holding such Certificate as the related REMIC generates losses. 
 For purposes of this calculation, (i) the Transferee is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but the tax
rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code if the Transferee has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two
years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of
the Code for the month of the transfer and the compounding period used by the Transferee. 
 [_] The transfer of the Certificate complies with U.S. Treasury
Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly, 
 (i) the Transferee is an “eligible corporation,” as defined in
U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from the Certificate will only be taxed in the United States; 
 (ii) at the time of the transfer, and at the close of the Transferee’s two fiscal years preceding the year of the transfer, the Transferee had gross assets for financial reporting purposes (excluding any obligation of a person related
to the Transferee within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million; 
 (iii) the Transferee will transfer the Certificate only to another “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the
requirements of Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5) of the U.S. Treasury Regulations; and 
 (iv) the Transferee determined the consideration paid to it to acquire the Certificate based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and
reinvestment assumptions, tax rates and other factors specific to the Transferee) that it has determined in good faith. 
 [_] None of the above. 

13. The Transferee is not an employee benefit plan or other plan subject to the prohibited transaction provisions of the Employee Retirement Income Security Act of
1974, as amended 

  

 K-3 

 
(“ERISA”) or Section 4975 of the Internal Revenue Code of 1974, as amended (the “Code”) (a “Plan”), or any person
(including, without limitation, an insurance company investing its general account, an investment manager, a named fiduciary or a trustee of any Plan) who is using “plan assets” within the meaning of the U.S. Department of Labor regulation
promulgated at 29 C.F.R. § 2510.3-101 (as modified by Section 3(42) of ERISA), of any Plan (a “Plan Investor”) to effect such acquisition. 
 IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly authorized officer and its corporate seal to be hereunto affixed, duly attested, this

 SECTION 2. Mortgage Loan Schedule. The Purchaser and the Seller have agreed upon which of the Mortgage Loans are to be

 (a) The information set forth in the Mortgage Loan Schedule is complete, true and correct as of the Cut-off Date; 
 (b) Except with respect to payments not yet 30 days past due, all payments required to be made up to the close of business on the Whole

than the owner of the related Mortgaged Property, directly or indirectly, for the payment of any amount required by 
  

 -8- 

 the Mortgage Note or Mortgage; and as of the Whole Loan Sale Date, except with respect to payments less
than 30 days past due, there has been no delinquency, exclusive of any period of grace, in any payment by the Mortgagor thereunder since origination; 
 (c) There are no delinquent taxes, insurance premiums or other outstanding charges that would jeopardize the lien priority of the Mortgage Loan; 
 (d) The terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written
instruments, recorded in the applicable public recording office if necessary to maintain the lien priority of the Mortgage, and which have been delivered to the Purchaser; and the substance of any such waiver, alteration or modification has been
approved by the title insurer, to the extent required by the related policy. No instrument of waiver, alteration or modification has been executed, and no Mortgagor has been released, in whole or in part, except in connection with an assumption
agreement approved by the title insurer, to the extent required by the policy, and which assumption agreement has been delivered to the Purchaser; 
 (e) The Mortgage Note and the Mortgage are not subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note and
the Mortgage, or the exercise of any right thereunder, render the Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury and no such right of rescission,
set-off, counterclaim or defense has been asserted with respect thereto; 
 (f) All buildings upon the Mortgaged Property are
insured by an insurer acceptable to Fannie Mae and Freddie Mac against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, pursuant to insurance policies conforming
to the requirements of the Pooling and Servicing Agreement. All such insurance policies contain a standard mortgagee clause naming the Responsible Party, its successors and assigns as mortgagee and all premiums thereon have been paid. If upon
origination of the Mortgage Loan, the Mortgaged Property was in an area identified on a Flood Hazard Map or Flood Insurance Rate Map issued by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been
made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration and conforming to the requirements of Fannie Mae or Freddie Mac is in effect. The Mortgage obligates the Mortgagor
thereunder to maintain all such insurance at the Mortgagor’s cost and expense, and on the Mortgagor’s failure to do so, authorizes the holder of the Mortgage to maintain such insurance at Mortgagor’s cost and expense and to seek
reimbursement therefor from the Mortgagor. The hazard insurance policy is the valid and binding obligation of the insurer, is in full force and effect, and will be in full force and effect and inure to the benefit of the Responsible Party upon the
consummation of the transactions contemplated by this Agreement. Neither the Responsible Party nor any applicable Option One Trust has engaged in, or has any knowledge of the Mortgagor’s having engaged in, any act or omission which would

Responsible Party nor any applicable Option One Trust has waived the performance by the Mortgagor of any action, if the Mortgagor’s failure to perform such action would cause the Mortgage Loan to be in default, nor has the Responsible Party or
any applicable Option One Trust waived any default resulting from any action or inaction by the Mortgagor; 
 (i) With respect
to any First Lien Mortgage Loan, the related Mortgage is a valid, existing and enforceable first lien on the related Mortgaged Property and, with respect to any Second Lien Mortgage Loan, the related Mortgage is a valid, existing and enforceable

acceptable to mortgage lending institutions generally and specifically referred to in the lender’s title insurance policy delivered to the originator of the related Mortgage Loan and which do not adversely affect the Appraised Value of the
related Mortgaged Property, and (4) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the related Mortgage or the use, enjoyment, value (as
determined by Appraised Value) or marketability of the related Mortgaged Property. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates (y) with
respect to any First Lien Mortgage Loan, a valid, subsisting and enforceable first lien and first priority security interest and (z) with respect to any Second Lien Mortgage Loan, a valid, subsisting and enforceable second lien and second
priority security 
  

 -10-

assign the same to the Purchaser. Except as set forth on the Mortgage Loan Schedule, the Mortgaged Property was not, as of the date of origination of the Mortgage Loan, subject to a mortgage, deed of trust, deed to secure debt or other security

not entitled to any refund of any amounts paid or due to the mortgagee pursuant to the Mortgage Note or Mortgage; 
 (n) As of
the Whole Loan Sale Date and immediately prior to the sale of the Mortgage Loan to the Seller, the Responsible Party or the Option One Trusts were the sole beneficial and equitable owner of the related Mortgage Note and the related Mortgage and had

 (o) All parties which have had any interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee or otherwise, are (or, during
the period in which they held and disposed of such interest, were) in compliance with any and all applicable “doing business” and licensing requirements of the laws of the state wherein the Mortgaged Property is located; 
 (p) The Mortgage Loan is covered by an ALTA lender’s title insurance policy and, in the case of an Adjustable Rate Mortgage Loan,

clauses (i)(1), (2) and (3) above) the Responsible Party, its successors and assigns as to the first or second, as applicable, priority lien of the Mortgage in the original principal amount of the Mortgage Loan and,
with respect to an Adjustable Rate Mortgage Loan, against any loss by reason of the invalidity or unenforceability of the lien resulting from the provisions of the Mortgage providing for adjustment in the Mortgage Rate and Monthly Payment.

sole insured of such lender’s title insurance policy, and such lender’s title insurance policy is in full force and effect and will be in full force and effect upon the consummation of the transactions contemplated by this Agreement. Such
lender’s title insurance policy has been duly and validly endorsed to the Purchaser or the assignment to the Purchaser of the Responsible Party’s interest therein does not require the consent of or notification to the related insurer. No
claims have been made under such lender’s title insurance policy, and no prior holder of the related Mortgage, including the Responsible Party, has done, by act or omission, anything which would impair the coverage of such lender’s title
insurance policy; 
 (q) As of the Whole Loan Sale Date, there is no default, breach, violation or event of acceleration
existing under the Mortgage or the Mortgage Note and no event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach, violation or event of acceleration, and the Responsible
Party has not waived (either for itself, for any applicable Option One Trust or for the Seller) any default, breach, violation or event of acceleration. For purposes of the foregoing, a delinquent payment of less than thirty (30) days on a
Mortgage Loan in and of itself does not constitute a default, breach, violation or event of acceleration (or an event which, with the passage of time or with notice and the expiration of any grace or cure period, has occurred that would constitute a
default, breach, violation or event of acceleration) with respect to such Mortgage Loan; 
 (r) As of the Whole Loan Sale

 -12- 

 (u) Payments on the Mortgage Loan shall commence (with respect to any newly originated
Mortgage Loans) or commenced no more than two months after the proceeds of the Mortgage Loan were disbursed. The Mortgage Loan bears interest at the Mortgage Rate. The Mortgage Note is payable on the first day of each month (except with respect to
the Mortgage Loans set forth in the Mortgage Loan Schedule as having Monthly Payments due on a day other than the first day of each month) in Monthly Payments, which, in the case of a Fixed Rate Mortgage Loans, are sufficient to fully amortize the

applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Rate and the monthly payment adjustments. Any interest required to be paid pursuant to state, federal and local law has been properly paid and credited. No

 SECTION 14. Agreement of Parties. The Seller, the Responsible Party and the Purchaser each agree to execute and deliver such instruments and take such actions as either of the others may, from time to time, reasonably request in

 SECTION 15.

Servicing Agreement or the Trust Fund. 
 (b) The Responsible Party agrees that the representations, warranties and agreements made by it
herein and in any certificate or other instrument delivered pursuant hereto shall be deemed to be relied upon by the Seller and the Purchaser, notwithstanding any investigation heretofore or hereafter made by the Seller or the Purchaser or on the

 -29-

 SECTION 16. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT

 SECTION 17.
Miscellaneous. This Agreement may be executed in two or more counterparts, each of which when so executed and delivered shall be an original, but all of which together shall constitute one and the same instrument. This Agreement shall inure

reference only and shall not limit or otherwise affect the meaning hereof. 
 SECTION 18. Intent of the Parties. It is the express
intent of the parties hereto that the conveyance of the Mortgage Loans by the Seller to the Purchaser as provided herein be, and be construed as, a sale of the Mortgage Loans by the Seller to the Purchaser and not as a pledge of the Mortgage Loans
by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the aforementioned intent of the parties, the Mortgage Loans are held to be property of the Seller, then (a) it is
the express intent of the parties hereto that such conveyance be deemed a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller and (b) (1) this Agreement shall also be deemed to be
a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (2) the conveyance provided for herein shall be deemed to be a grant by the Seller to the Purchaser of a security interest in all of the
Seller’s right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing
into cash, instruments, securities or other property, including without limitation all amounts, other than investment earnings, from time to time held or invested in the Collection Account whether in the form of cash, instruments, securities or
other property; (3) the possession by the Purchaser or its agent of Mortgage Notes, the related Mortgages and such other items of property that constitute instruments, money, negotiable documents or chattel paper shall be deemed to be
“possession” by the secured party for purposes of perfecting the security interest pursuant to the New York Uniform Commercial Code; and (4) notifications to persons holding such property and acknowledgments, receipts or confirmations
from persons holding such property shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security
interest under applicable law. Any assignment of the interest of the Purchaser as contemplated by Section 4(d) hereof shall also be 
  

 -30- 

 deemed to be an assignment of any security interest created hereby. The Seller and the Purchaser shall,
to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security
interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement and the Pooling and Servicing Agreement.

 SCHEDULE I 
 The Seller hereby represents, warrants, and covenants to the Purchaser as follows on the Closing Date and on each Distribution Date thereafter: 
 General 
 1. This Agreement creates a
valid and continuing security interest (as defined in the applicable Uniform Commercial Code (“UCC”)) in the Mortgage Loans in favor of the Purchaser which security interest is prior to all other liens, and is enforceable as such as
against creditors of and purchasers from the Seller. 
 2. The Mortgage Loans constitute “general intangibles” or
“instruments” within the meaning of the applicable UCC. 
 3. The Collection Account and all subaccounts thereof constitute either
a deposit account or a securities account. 
 4. To the extent that payments and collections received or made with respect to the Mortgage
Loans constitute securities entitlements, such payments and collections have been and will have been credited to the Collection Account. The securities intermediary for the Collection Account has agreed to treat all assets credited to the Collection
Account as “financial assets” within the meaning of the applicable UCC. 
 Creation 
 5. The Seller owns and has equitable title to the Mortgage Loans free and clear of any lien, claim or encumbrance of any Person, excepting only liens for
taxes, assessments or similar governmental charges or levies incurred in the ordinary course of business that are not yet due and payable or as to which any applicable grace period shall not have expired, or that are being contested in good faith by
proper proceedings and for which adequate reserves have been established, but only so long as foreclosure with respect to such a lien is not imminent and the use and value of the property to which the lien attaches is not impaired during the
pendency of such proceeding. 
 6. The Seller has received all consents and approvals to the sale of the Mortgage Loans hereunder to the
Purchaser required by the terms of the Mortgage Loans that constitute instruments. 
 7. To the extent the Collection Account or subaccounts
thereof constitute securities entitlements, certificated securities or uncertificated securities, the Seller has received all consents and approvals required to transfer to the Purchaser its interest and rights in the Collection Account hereunder.

 Perfection 
 8. The
Seller has caused or will have caused, within ten days after the effective date of this Agreement, the filing of all appropriate financing statements in the proper 
  

 Sch.I-1 

 filing office in the appropriate jurisdictions under applicable law in order to perfect the sale of the Mortgage Loans
from the Seller to the Purchaser and the security interest in the Mortgage Loans granted to the Purchaser hereunder. 
 9. With respect to
the Collection Account and all subaccounts that constitute deposit accounts, either: 
 (i) the Seller has delivered to the
Purchaser a fully-executed agreement pursuant to which the bank maintaining the deposit accounts has agreed to comply with all instructions originated by the Purchaser directing disposition of the funds in the Collection Account without further
consent by the Seller; or 
 (ii) the Seller has taken all steps necessary to cause the Purchaser to become the account holder
of the Collection Account. 
 10. With respect to the Collection Account or subaccounts thereof that constitute securities accounts or
securities entitlements, either: 
 (i) the Seller has caused or will have caused, within ten days after the effective date of
this Agreement, the filing of all appropriate financing statements in the proper filing office in the appropriate jurisdictions under applicable law in order to perfect the security interest in the Collection Account granted by the Seller to the
Purchaser; or 
 (ii) the Seller has delivered to the Purchaser a fully-executed agreement pursuant to which the securities
intermediary has agreed to comply with all instructions originated by the Purchaser relating to the Collection Account without further consent by the Purchaser; or 
 (iii) the Seller has taken all steps necessary to cause the securities intermediary to identify in its records the Purchaser as the person
having a security entitlement against the securities intermediary in the Collection Account. 
 Priority 
 11. Other than the transfer of the Mortgage Loans to the Purchaser pursuant to this Agreement, the Seller has not pledged, assigned, sold, granted a
security interest in, or otherwise conveyed any of the Mortgage Loans. The Seller has not authorized the filing of, or is not aware of any financing statements against the Seller that include a description of collateral covering the Mortgage Loans
other than any financing statement relating to the security interest granted to the Purchaser hereunder or that has been terminated. 
 12.
The Seller is not aware of any judgment, ERISA or tax lien filings against the Seller. 
 13. The Trustee (or the Custodian on its behalf)
has in its possession all original copies of the Mortgage Notes that constitute or evidence the Mortgage Loans. To the Seller’s knowledge, none of the instruments that constitute or evidence the Mortgage Loans has 
  

 Sch.I-2 

 any marks or notations indicating that they have been pledged, assigned or otherwise conveyed to any Person other than
the Purchaser or its designee. All financing statements filed or to be filed against the Seller in favor of the Purchaser in connection herewith describing the Mortgage Loans contain a statement to the following effect: “A purchase of or
security interest in any collateral described in this financing statement will violate the rights of the Purchaser.” 
 14. Neither the
Collection Account nor any subaccount thereof is in the name of any person other than the Seller or the Purchaser or in the name of its nominee. The Seller has not consented for the securities intermediary of the Collection Account to comply with
entitlement orders of any person other than the Purchaser or its designee. 
 15. Survival of Perfection Representations.
Notwithstanding any other provision of this Agreement or any other transaction document, the Perfection Representations contained in this Schedule shall be continuing, and remain in full force and effect (notwithstanding any replacement of the
Servicer or termination of the Servicer’s rights to act as such) until such time as all obligations under this Agreement have been finally and fully paid and performed. 
 16. No Waiver. The parties to this Agreement (i) shall not, without obtaining a confirmation of the then-current rating of the Certificates
waive any of the Perfection Representations, and (ii) shall provide the Rating Agencies with prompt written notice of any breach of the Perfection Representations, and shall not, without obtaining a confirmation of the then-current rating of
the Certificates (as determined after any adjustment or withdrawal of the ratings following notice of such breach) waive a breach of any of the Perfection Representations. 
 17. Seller to Maintain Perfection and Priority. The Seller covenants that, in order to evidence the interests of the Seller and the Purchaser
under this Agreement, the Seller shall take such action, or execute and deliver such instruments (other than effecting a Filing (as defined below), unless such Filing is effected in accordance with this paragraph) as may be necessary or advisable
(including, without limitation, such actions as are requested by the Purchaser) to maintain and perfect, as a first priority interest, the Purchaser’s security interest in the Mortgage Loans. The Seller shall, from time to time and within the
time limits established by law, prepare and present to the Purchaser or its designee to authorize (based in reliance on the Opinion of Counsel hereinafter provided for) the Seller to file, all financing statements, amendments, continuations, initial
financing statements in lieu of a continuation statement, terminations, partial terminations, releases or partial releases, or any other filings necessary or advisable to continue, maintain and perfect the Purchaser’s security interest in the
Mortgage Loans as a first-priority interest (each a “Filing”). The Seller shall present each such Filing to the Purchaser or its designee together with (x) an Opinion of Counsel to the effect that such Filing is
(i) consistent with the grant of the security interest to the Purchaser pursuant to Section 17 of this Agreement, (ii) satisfies all requirements and conditions to such Filing in this Agreement and (iii) satisfies the
requirements for a Filing of such type under the Uniform Commercial Code in the applicable jurisdiction (or if the Uniform Commercial Code does not apply, the applicable statute governing the perfection of security interests), and (y) a form of
authorization for the Purchaser’s signature. Upon receipt of such Opinion of Counsel and form of authorization, the Purchaser shall promptly authorize in writing the Seller to, and the Seller shall, effect such Filing under the UCC without the
signature of the Seller or the Purchaser where 
  

 Sch.I-3 

 allowed by applicable law. Notwithstanding anything else in the transaction documents to the contrary, the Seller shall
not have any authority to effect a Filing without obtaining written authorization from the Purchaser or its designee.
