THIS POOLING AND SERVICING AGREEMENT, dated as of February 1, 2006, among HSI ASSET SECURITIZATION CORPORATION, as depositor (the “Depositor”), OPTION ONE MORTGAGE CORPORATION, a California Corporation, as originator (in such capacity, the “Originator”) and servicer (in such capacity, the “Servicer”), XXXXX FARGO BANK, N.A., a national banking association, as master servicer (in such capacity, the “Master Servicer”) as securities administrator (in such capacity, the “Securities Administrator”) and as custodian (in such capacity, “the Custodian”), and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking association, as trustee (the “Trustee”).

W I T N E S S E T H:

In consideration of the mutual agreements herein contained, the parties hereto agree as follows:

PRELIMINARY STATEMENT

The Securities Administrator on behalf of the Trust Fund (exclusive of (i) the Swap Agreement, (u) the Cap Agreement (iii) the right to receive and the obligation to pay Basis Risk Carryover Amounts, (iv) the Excess Reserve Fund Account, (v) the Supplemental Interest Trust and the Supplemental Interest Trust Account and (vi) the obligations to pay Class I Shortfalls (collectively, the “Excluded Trust Assets”) shall elect that two segregated asset pools within the Trust Fund be treated for federal income tax purposes as comprising three real estate mortgage investment conduits under Section 860D of the Code (each a “REMIC” or, in the alternative, “REMIC 1,” REMIC 2” and “REMIC 3,”; REMIC 3 also being referred to herein as the “Upper Tier REMIC.”) Any inconsistencies or ambiguities in this Agreement or in the administration of this Agreement shall be resolved in a manner that preserves the validity of such REMIC election.

Each Certificate, other than the Class R Certificates, represents ownership of a regular interest in the Upper Tier REMIC for purposes of the REMIC Provisions. In addition, each Certificate, other than the Class R, Class X and Class P Certificates, represents (i) the right to receive payments with respect to any Basis Risk Carryover Amounts and (ii) the obligation to pay Class I Shortfalls. The Class R Certificate represents ownership of the sole Class of residual interest in each of REMIC 1, REMIC 2 and the Upper Tier REMIC for purposes of the REMIC Provisions.

The Upper Tier REMIC shall hold as its assets the uncertificated Lower Tier Interests in REMIC 2, other than the Class LT2-R interest, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 2 for purposes of the REMIC Provisions. REMIC 2 shall hold as its assets the uncertificated Lower Tier Interests in REMIC 1, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 1. REMIC 1 shall hold as its assets the property of the Trust Fund other than the Lower Tier Interests in REMIC 1 and REMIC 2 and the Excluded Trust Assets.

REMIC 1:

The following table sets forth the designations, principal balances and interest rates for each interest in REMIC 1, each of which (other than the Class LT1-R Lower Tier Interest) is hereby designated as a regular interest in REMIC 1 (the “REMIC 1 Regular Interests”):

(1)

For any Distribution Date (and the related Interest Accrual Period) the interest rate for the Class LT1-A Interest shall be the Net WAC Rate.

(2)

For any Distribution Date (and the related Interest Accrual Period) the interest rate for each of these Lower Tier Interests shall be the lesser of (i) 10.10% and (ii) the product of (a) the Net WAC Rate and (b) 2.

(3)

For any Distribution Date (and the related Interest Accrual Period) the interest rate for each of these Lower Tier Interests shall be the excess, if any, of (i) the product of (a) the Net WAC Rate and (b) 2, over (ii) 10.10%.

(4)

The Class LT1-R interest shall not have a principal amount and shall not bear interest. The Class LT1-R interest is hereby designated as the sole class of residual interest in REMIC 1.

On each Distribution Date, the Securities Administrator shall first pay or charge as an expense of REMIC 1 all expenses of the Trust Fund for such Distribution Date, other than any Net Swap Payment or Swap Termination Payment required to be made from the Trust Fund.

On each Distribution Date the Securities Administrator shall distribute the Interest Remittance Amount (net of expenses described in the preceding paragraph) with respect to each of the Lower Tier Interests in REMIC 1 based on the above-described interest rates.

On each Distribution Date, the Securities Administrator shall distribute the Principal Remittance Amount with respect to the Lower Tier Interests in REMIC 1, first to the Class LT1-A Interest until its principal balance is reduced to zero, and then sequentially, to the other Lower Tier Interests in REMIC 1 in ascending order of their numerical class designation, and, with respect to each pair of classes having the same numerical designation, in equal amounts to each such class, until the principal balance of each such class is reduced to zero. All losses on the Mortgage Loans shall be allocated among the Lower Tier Interests in REMIC 1 in the same manner that principal distributions are allocated.

On each Distribution Date, the Securities Administrator shall distribute the Prepayment Premiums collected during the preceding Prepayment Period to the Class LT1-V38 Lower Tier Interests.

REMIC 2:

The following table sets forth the designations, principal balances and interest rates for each interest in REMIC 2, each of which (other than the Class LT2-R interest) is hereby designated as a regular interest in REMIC 2 (the “REMIC 2 Regular Interests”):

REMIC 2 Lower Tier Class Designation	REMIC 2 Lower Tier Interest Rate	Initial Class Principal Amount	Corresponding Class of Certificate(s)
Class LT2-I-A	(1)	(4)	I-A

Class LT2-R	(3)	(3)	R

___________________________

(1)

For any Distribution Date (and the related Interest Accrual Period) the interest rate for each of these Lower Tier Interests in REMIC 2 is a per annum rate equal to the weighted average of the interest rates on the Lower Tier Interests in REMIC 1 for such Distribution Date; provided, however, that (i) for any Distribution Date on which the Class LT2-IO Interest is entitled to a portion of the interest accruals on a Lower Tier Interest in REMIC 1 having an “F” in its class designation, as described in footnote two below, such weighted average shall be computed by first subjecting the rate on such Lower Tier Interest in REMIC 1 to a cap equal to Swap LIBOR for such Distribution Date.

(2)

The Class LT2-IO is an interest only class that does not have a principal balance. For only those Distribution Dates listed in the first column in the table below, the Class LT2-IO shall be entitled to interest accrued on the Lower Tier Interest in REMIC 1 listed in second column in the table below at a per annum rate equal to the excess, if any, of (i) the interest rate for such Lower Tier Interest in REMIC 1 for such Distribution Date over (ii) Swap LIBOR for such Distribution Date.

(3)

The Class LT2-R interest is the sole class of residual interests in REMIC 2. It does not have an interest rate or a principal balance.

(4)

This Lower Tier Interest shall have an initial class principal amount equal to one-half of the initial Class Principal Amount of its Corresponding Class of Certificates.

(5)

This Lower Tier Interest shall have an initial class principal amount equal to the excess of (i) the Pool Stated Principal Balance as of the Cut-off Date, over (ii) the aggregate initial Class Principal Amount of each other regular interest in REMIC 2 (other than any interest-only Lower Tier Interest).

(a) The Depositor, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee for the benefit of the Certificateholders, without recourse, all the right, title and interest of the Depositor in and to the Trust Fund.

Concurrently with the execution of this Agreement, the Derivative Agreements shall be delivered to the Securities Administrator. In connection therewith, the Depositor hereby directs the Securities Administrator (solely in its capacity as Securities Administrator of the Supplemental Interest Trust) and the Securities Administrator is hereby authorized to execute and deliver each of the Derivative Agreements (on behalf of the Supplemental Interest Trust), for the benefit of Certificateholders. The Depositor, the Sponsor, the Master Servicer, the Servicer, the Originator and the Certificateholders (by their acceptance of such Certificates) acknowledge and agree that the Securities Administrator is executing and delivering the Derivative Agreements solely in its capacity as Securities Administrator of the Supplemental Interest Trust and not in its individual capacity. The Securities Administrator shall have no duty or responsibility to enter into any other interest rate swap agreement upon the expiration or termination of the Swap Agreement or interest rate cap agreement upon the termination of the Cap Agreement unless so directed by the Depositor.

Concurrently with the execution and delivery of this Agreement, the Depositor does hereby assign to the Trustee all of its rights and interest under the Purchase Agreement, including the right to enforce the Sponsor’s obligation to repurchase or substitute defective Mortgage Loans under Section 5 of the Purchase Agreement.

If in connection with any Mortgage Loan, the original Mortgage cannot be delivered with evidence of recording thereon on or prior to the Closing Date because of a delay caused by the public recording office where such Mortgage has been delivered for recordation or because such Mortgage has been lost or because such public recording office retains the original recorded Mortgage, the Originator shall deliver or cause to be delivered to the Custodian, (A) in the case of a delay caused by the public recording office, a copy of such Mortgage certified by the Originator, escrow agent, title insurer or closing attorney to be a true and complete copy of the original recorded Mortgage and (B) in the case where a public recording office retains the original recorded Mortgage or in the case where a Mortgage is lost after recordation in a public recording office, a copy of such Mortgage certified by such public recording office to be a true and complete copy of the original recorded Mortgage;

(v)

originals or a certified copy of each modification agreement, if any;

(vi)

the originals of all intervening assignments of Mortgage with evidence of recording thereon evidencing a complete chain of ownership from the originator to the last assignee, or if any such intervening assignment of Mortgage has not been returned from the applicable public recording office or has been lost or if such public recording office retains the original recorded intervening assignments of Mortgage, a photocopy of such intervening assignment of Mortgage, together with (A) in the case of a delay caused by the public recording office, an officer’s certificate of the Originator, escrow agent, closing attorney or the title insurer insuring the Mortgage stating that such intervening assignment of Mortgage has been delivered to the appropriate public recording office for recordation and that such original recorded intervening assignment of Mortgage or a copy of such intervening assignment of Mortgage certified by the appropriate public recording office to be a true and complete copy of the original recorded intervening assignment of Mortgage will be promptly delivered to the Custodian upon receipt thereof by the party delivering the officer’s certificate or by the Originator; or (B) in the case of an intervening assignment of mortgage where a public recording office retains the original recorded intervening assignment of Mortgage or in the case where an intervening assignment of Mortgage is lost after recordation in a public recording office, a copy of such intervening assignment of Mortgage with recording information thereon certified by such public recording office to be a true and complete copy of the original recorded intervening assignment of Mortgage;

(ix)

if applicable, the original of any Primary Mortgage Insurance Policy or certificate or, an electronic certification, evidencing the existence of the Primary Mortgage Insurance Policy or certificate, if private mortgage guaranty insurance is required; and

To the extent not previously delivered to the Sponsor pursuant to the Master MLPSA, the Originator shall promptly upon receipt from the respective recording office cause to be delivered to the Custodian the original recorded document described in clauses (iv) and (vi) above.

From time to time, the Originator, the Depositor or the Servicer, as applicable, shall forward to the Custodian additional original documents, additional documents evidencing an assumption, modification, consolidation or extension of a Mortgage Loan, in accordance with the terms of this Agreement upon receipt of such documents. All such mortgage documents held by the Custodian as to each Mortgage Loan shall constitute the “Custodial File”.

To the extent not previously delivered to the Sponsor pursuant to the Master MLPSA, on or prior to the Closing Date, the Originator shall deliver to the Custodian Assignments of Mortgages, in blank, for each Mortgage Loan. No later than thirty (30) Business Days following the later of the Closing Date and the date of receipt by the Servicer of the complete recording information for a Mortgage, the Servicer shall promptly submit or cause to be submitted for recording, at the expense of the Originator and at no expense to the Trust Fund, the Trustee, the Servicer or the Depositor, in the appropriate public office for real property records, each Assignment of Mortgage referred to in Section 2.01(b)(ii). Notwithstanding the foregoing, however, for administrative convenience and facilitation of servicing and to reduce closing costs, the Assignments of Mortgage shall not be required to be completed and submitted for recording with respect to any Mortgage Loan if the Trustee and each Rating Agency have received an Opinion of Counsel, satisfactory in form and substance to the Trustee and each Rating Agency to the effect that the recordation of such Assignments of Mortgage in any specific jurisdiction is not necessary to protect the Trust Fund’s interest in the related Mortgage Note. If the Assignment of Mortgage is to be recorded, the Mortgage shall be assigned by the Originator, at the expense of the Originator, to “Deutsche Bank National Trust Company, as trustee under the Pooling and Servicing Agreement dated as of February 1, 2006, for HSI Asset Securitization Corporation Trust 2006-OPT2”. In the event that any such Assignment of Mortgage is lost or returned unrecorded because of a defect therein, the Originator shall promptly cause to be delivered a substitute Assignment of Mortgage to cure such defect and thereafter cause each such assignment to be duly recorded at no expense to the Trust Fund.

In the event that such original or copy of any document submitted for recordation to the appropriate public recording office is not so delivered to the Trustee within 180 days (or such other time period as may be required by any Rating Agency) following the Closing Date, and in the event that the Originator does not cure such failure within 30 days of discovery or receipt of written notification of such failure from the Depositor, the related Mortgage Loan shall, upon the request of the Depositor, be repurchased by the Originator at the price and in the manner specified in Section 2.03. The foregoing repurchase obligation shall not apply in the event that the Originator cannot deliver such original or copy of any document submitted for recordation to the appropriate public recording office within the specified period due to a delay caused by the recording office in the applicable jurisdiction; provided, that the Originator shall instead deliver a recording receipt of such recording office or, if such recording receipt is not available, an officer’s certificate of an officer of the Originator, confirming that such document has been accepted for recording.

Notwithstanding anything to the contrary contained in this Section 2.01, in those instances where the public recording office retains or loses the original Mortgage or assignment after it has been recorded, the obligations of the Originator shall be deemed to have been satisfied upon delivery by the Originator to the Trustee, prior to the Closing Date of a copy of such Mortgage or assignment, as the case may be, certified (such certification to be an original thereof) by the public recording office to be a true and complete copy of the recorded original thereof.

(c)

The Depositor does hereby establish, pursuant to the further provisions of this Agreement and the laws of the State of New York, an express trust (the “Trust”) to be known, for convenience, as “HSI Asset Securitization Corporation Trust 2006-OPT2” and Deutsche Bank National Trust Company is hereby appointed as Trustee and Xxxxx Fargo Bank, N.A. is appointed as Securities Administrator in accordance with the provisions of this Agreement.

Upon discovery by the Originator, the Depositor, the Securities Administrator, the Trustee, the Master Servicer or the Servicer of a breach of any of the foregoing representations and warranties, the party discovering such breach shall give prompt written notice to the others.

(d)

Within 30 days of the earlier of either discovery by or notice to the Originator that any Mortgage Loan does not conform to the requirements as determined in the Custodian’s review of the related Custodial File or within 60 days of the earlier of either discovery by or notice to the Originator of any breach of a representation or warranty referred to in Section 2.03(b) that materially and adversely affects the value of any Mortgage Loan or the interest of the Trustee or the Certificateholders therein, the Originator shall use its best efforts to cause to be remedied a material defect in a document constituting part of a Mortgage File or promptly to cure such breach in all material respects and, if such defect or breach cannot be remedied, the Originator shall, at the Depositor’s option as specified in writing and provided to the Originator and the Trustee, (i) if such 30- or 60-day period, as applicable, expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section 2.03; or (ii) repurchase such Mortgage Loan at the Repurchase Price; provided, however, that any such substitution pursuant to clause (i) above shall not be effected prior to the delivery to the Custodian of a Request for Release substantially in the form of Exhibit J, and the delivery of the Mortgage File to the Custodian for any such Substitute Mortgage Loan. Notwithstanding the foregoing, a breach (i) which causes a Mortgage Loan not to constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code or (ii) of any of the representations and warranties set forth in items number (44), (47), (55), (57), (58), (59), (60), and (64) of Schedule IV with respect to any Group I Mortgage Loan, will be deemed automatically to materially and adversely affect the value of such Mortgage Loan and the interests of the Trustee and Certificateholders in such Mortgage Loan, requiring the repurchase or substitution of such Mortgage Loan by the Originator. In the event that the Trustee receives notice of a breach by the Originator of any of the representations and warranties described in the immediately preceding sentence, the Trustee shall give notice of such breach to the Originator and request the Originator to substitute such Mortgage Loan or to repurchase such Mortgage Loan at the Repurchase Price within sixty (60) days of the receipt of such notice.

No substitution is permitted to be made with respect to any Distribution Date after the end of the related Prepayment Period. Scheduled Payments due with respect to Substitute Mortgage Loans in the Due Period of substitution shall not be part of the Trust Fund and will be retained by the Originator on the next succeeding Distribution Date. For the Due Period of substitution, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for such Due Period and thereafter the Originator shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan.

(f)

The Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Substitute Mortgage Loan or Loans and the Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee and the Custodian. Upon such substitution, the Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Originator shall be deemed to have made with respect to such Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(b) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Custodian shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Originator and the Trustee, upon receipt of a Request for Release certifying that all amounts required to be deposited in accordance with this Section 2.03(f) have been deposited in the Collection Account, shall execute and deliver at the Originator’s direction such instruments of transfer or assignment prepared by the Originator in each case without recourse, as shall be necessary to vest title in the Originator of the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

(g)

For any month in which the Originator substitutes one or more Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (if any) by which the aggregate unpaid principal balance of all such Substitute Mortgage Loans as of the date of substitution is less than the aggregate unpaid principal balance of all such Deleted Mortgage Loans. The amount of such shortage plus an amount equal to the aggregate of any unreimbursed Advances with respect to such Deleted Mortgage Loans (collectively, the “Substitution Adjustment Amount”) shall be remitted by the Originator to the Servicer for deposit into the Collection Account on or before the Distribution Account Deposit Date for the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be purchased or replaced hereunder.

(h)

In addition to the repurchase or substitution obligations referred to in Section 2.03(d) above and Section 2.03 (k) below, the Originator or the Sponsor, as applicable, shall indemnify the Depositor, any of its Affiliates, the Master Servicer, the Servicer, the Securities Administrator, the Trustee and the Trust and hold such parties harmless against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses (including, without limitation, any taxes payable by the Trust) resulting from any third party claim, demand, defense or assertion based on or grounded upon, or resulting from, a breach by the Originator or the Sponsor, as applicable, of any of its representations and warranties or obligations contained in this Agreement.

(i)

The Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee, the Custodian, the Master Servicer and the Securities Administrator.

(j)

In the event that a Mortgage Loan shall have been repurchased pursuant to this Agreement or the Purchase Agreement, the proceeds from such repurchase shall be deposited by the Servicer in the Collection Account pursuant to Section 3.10 on or before the Remittance Date for the Distribution Date in the month following the month during which the Originator or Sponsor became obligated to repurchase or replace such Mortgage Loan and upon such deposit of the Repurchase Price, and receipt of a Request for Release in the form of Exhibit J hereto, the Custodian shall release the related Custodial File held for the benefit of the Certificateholders to the Originator or the Sponsor, as applicable, as directed by the Servicer, and the Trustee shall execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. In accordance with Section 12.05(a), the Securities Administrator shall promptly notify each Rating Agency of a purchase of a Mortgage Loan pursuant to this Section 2.03.

The Trustee acknowledges that, except as provided in Section 5 of the Purchase Agreement, the Sponsor shall not have any obligation or liability with respect to any breach of a representation or warranty made by it with respect to a Mortgage Loan sold by it, provided that such representation or warranty was also made by the Originator with respect to the related Mortgage Loan. It is understood and agreed that the representations and warranties of the Sponsor set forth in Section 4 of the Purchase Agreement and assigned to the Trustee by the Depositor hereunder shall survive the transfer of the Mortgage Loans by the Depositor to the Trustee on the Closing Date, and shall inure to the benefit of the Trustee and the Certificateholders notwithstanding any restrictive or qualified endorsement on any Mortgage Note or Assignment of Mortgage and shall continue throughout the term of this Agreement.

In the event of any such repurchase or substitution of a Mortgage Loan by the Sponsor, the procedures set forth in Sections 2.03(e), (f), (g), (h), (i) and (j) shall apply to the Sponsor in the same manner and to the same extent that they are applicable to the Originator. It is understood and agreed that the obligations of the Sponsor under this Agreement to cure, repurchase or substitute any Mortgage Loan as to which a breach of a representation and warranty has occurred and is continuing, together with any related indemnification obligations of the Sponsor set forth in Section 2.03(h), shall constitute the sole remedies against the Sponsor available to the Certificateholders, the Depositor and any of its affiliates, or the Trustee on their behalf.

Section 3.01

Servicer to Service Mortgage Loans. (a) For and on behalf of the Certificateholders, the Servicer shall service and administer the Mortgage Loans in accordance with the terms of this Agreement and the respective Mortgage Loans and, to the extent consistent with such terms, in accordance with Accepted Servicing Practices, but without regard to:

(i)

any relationship that the Servicer, any Subservicer or any Affiliate of the Servicer or any Subservicer may have with the related Mortgagor;

The Trustee shall not be liable for the actions of the Servicer or any Subservicers under such powers of attorney. Notwithstanding anything contained herein to the contrary, no Servicer or Subservicer shall without the Trustee’s consent: (i) initiate any action, suit or proceeding solely under the Trustee’s name without indicating the Servicer’s or Subservicer’s, as applicable, representative capacity, or (ii) knowingly take any action with the intent to, or which actually does cause, the Trustee to be registered to do business in any state.

Any cost incurred by the Servicer or by Subservicers in effecting the timely payment of taxes and assessments on a Mortgaged Property shall not be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit.

(c)

Notwithstanding anything in this Agreement to the contrary, the Servicer may not make any future advances with respect to a Mortgage Loan (except as provided in Section 4.01) and the Servicer shall not (i) permit any modification with respect to any 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 Mortgage Loan (except for a reduction of interest payments resulting from the application of the Servicemembers Civil Relief Act or any similar state statutes) or (ii) permit 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 proposed Treasury regulations promulgated thereunder) and (B) cause either the Upper Tier REMIC or a Lower Tier REMIC to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions after the startup day” under the REMIC Provisions, or (iii) except as provided in Section 3.07(a), waive any Prepayment Charges.

(d)

The Servicer may delegate its responsibilities under this Agreement; provided, however, that no such delegation shall release the Servicer from the responsibilities or liabilities arising under this Agreement.

Section 3.02

Subservicing Agreements between Servicer and Subservicers; Use of Subcontractors. (a) The Servicer may enter into a subservicing agreement with a Subservicer, for the servicing and administration of the Mortgage Loans (“Subservicing Agreement”) without obtaining the prior consent of the Trustee, the Depositor, the Master Servicer, Securities Administrator or other parties hereto to the utilization of any such Subservicer, provided the provisions of such Subservicing Agreement comply with the requirements set forth of this Section 3.02. None of the Trustee, the Master Servicer or the Depositor shall be required to review or consent to such Subservicing Agreement and shall have no liability in connection therewith.

(b)

Each Subservicer shall be (i) authorized to transact business in the state or states in which the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Subservicer to perform its obligations hereunder and under the Subservicing Agreement and (ii) a Xxxxxxx Mac or Xxxxxx Mae approved mortgage servicer. Each Subservicing Agreement must impose on the Subservicer requirements conforming to the provisions set forth in Sections 3.08, 3.22, 3.23, 3.24, 3.30, 6.05, 6.06, 7.01(i) and Exhibit S of this Agreement to the same extent as if such Subservicer were the Servicer and otherwise provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Servicer shall examine each Subservicing Agreement and will be familiar with the terms thereof in order to determine that the foregoing requirements have been incorporated into the Subservicing Agreement and that the terms thereof are not otherwise inconsistent with any of the provisions of this Agreement. The Servicer and the Subservicers may enter into and make amendments to the Subservicing Agreements or enter into different forms of Subservicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Trustee, the Depositor, the Master Servicer or the Securities Administrator without their prior written consent. Any variation without the consent of the Trustee, Depositor and Master Servicer from the requirements set forth in Sections 3.08, 3.22, 3.23, 3.24, 3.30, 6.05, 6.06, 7.01(i) and Exhibit S, are conclusively deemed to be inconsistent with this Agreement and therefore prohibited. The Servicer shall deliver to the Master Servicer, the Securities Administrator, the Trustee and the Depositor copies of all Subservicing Agreements, and any amendments or modifications thereof, promptly upon the Servicer’s execution and delivery of such instruments.

(c)

As part of its servicing activities hereunder, the Servicer (except as otherwise provided in the last sentence of this paragraph) shall enforce the obligations of each Subservicer under the related Subservicing Agreement, including, without limitation, (i) any obligation to make advances in respect of delinquent payments as required by a Subservicing Agreement and (ii) the reporting obligations set forth under Section 3.22, 3.23, 3.24 and 3.30 hereof to the same extent as if such Subservicer were the Servicer. The Servicer shall be responsible for obtaining from each Subservicer and delivering to the Master Servicer, the Securities Administrator and the Depositor (i) any servicer annual compliance statement required to be delivered by such Subservicer under Section 3.24(b); (ii) any report on assessments and attestations of compliance with Relevant Servicing Criteria required to be delivered by the Subservicer pursuant to Sections 3.22 and 3.23; and (iii) any certifications required to be delivered under Section 3.24(a) to the Master Servicer or such other Person that will be responsible for signing the Xxxxxxxx-Xxxxx Certification as and where required to be delivered hereunder. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Subservicing Agreements, and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement, to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans or (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed.

(d)

It shall not be necessary for the Servicer to seek the consent of the Depositor, the Trustee, the Master Servicer, the Securities Administrator or other parties hereto to the utilization of a Subcontractor. The Servicer shall give prompt written notice to the Master Servicer and the Depositor of the appointment of any Subcontractor and provide a written description (in form and substance satisfactory to the Depositor) of the role and function of each Subcontractor specifying (i) which, if any, of such Subcontractors are Servicing Function Participants, (ii) which elements of the Servicing Criteria set forth under Item 1122(d) of Regulation AB will be addressed in assessments and attestations of compliance with Relevant Servicing Criteria provided by such Subcontractor identified pursuant to clause (i) of this paragraph.

(e)

As a condition to the utilization of any Subcontractor determined to be a Servicing Function Participant, the Servicer shall cause any such Subcontractor used by the Servicer (or by any Subservicer) to comply with the provisions of Sections 3.22, 3.23, 3.24, 3.30, 6.05, 6.06, 7.01(i) and Exhibit S of this Agreement to the same extent as if such Subcontractor were the Servicer. The Servicer shall be responsible for obtaining from each Subcontractor and delivering the Securities Administrator, the Master Servicer and the Depositor any assessments and attestations of compliance required to be delivered by such Subcontractor pursuant to Sections 3.22 and 3.23, in each case as and when required to be delivered.

Section 3.03

Successor Subservicers. The Servicer shall be entitled to terminate any Subservicing Agreement and the rights and obligations of any Subservicer pursuant to any Subservicing Agreement in accordance with the terms and conditions of such Subservicing Agreement. In the event of termination of any Subservicer, all servicing obligations of such Subservicer shall be assumed simultaneously by the Servicer without any act or deed on the part of such Subservicer or Servicer, and the Servicer either shall service directly the related Mortgage Loans or shall enter into a Subservicing Agreement with a successor subservicer which qualifies under Section 3.02.

Any Subservicing Agreement shall include the provision that such agreement may be immediately terminated by the Master Servicer without fee, in accordance with the terms of this Agreement, in the event that the Servicer shall, for any reason, no longer be the Servicer (including termination due to an Event of Default).

Section 3.04

Liability of the Servicer. Notwithstanding any subservicing agreement or the provisions of this Agreement relating to agreements or arrangements between the Servicer and a Subservicer, Subcontractor or other third party or reference to actions taken through a Subservicer, a Subcontractor, another third party or otherwise, the Servicer shall remain obligated and primarily liable to the Trustee and the Trust Fund for the servicing and administering of the Mortgage Loans in accordance with the provisions hereof without diminution of such obligation or liability by virtue of any subservicing, subcontracting or other agreements or arrangements or by virtue of indemnification from a Subservicer, Subcontractor or a third party and to the same extent and under the same terms and conditions as if the Servicer alone were servicing the Mortgage Loans, including with respect to compliance with Item 1122 of Regulation AB. The Servicer shall be entitled to enter into any agreement with a Subservicer, Subcontractor or other third party for indemnification of the Servicer by such Subservicer, Subcontractor or third party and nothing contained in the Agreement shall be deemed to limit or modify such indemnification.

Section 3.05

No Contractual Relationship between Subservicers and the Master Servicer. Any Subservicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Subservicer in its capacity as such shall be deemed to be between the Subservicer and the Servicer alone, and none of the Trustee, the Depositor, the Securities Administrator, or the Master Servicer (nor any successor master servicer) shall be deemed a party thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Subservicer except as set forth in Section 3.06. The Servicer shall be solely liable for all fees owed by it to any Subservicer, irrespective of whether the Servicer’s compensation pursuant to this Agreement is sufficient to pay such fees.

Section 3.06

Assumption or Termination of Subservicing Agreements by Master Servicer. In the event the Servicer at any time shall for any reason no longer be the Servicer (including by reason of the occurrence of an Event of Default), the Master Servicer, or its designee or the successor servicer if the successor is not the Master Servicer, shall thereupon assume all of the rights and obligations of the Servicer under each Subservicing Agreement that the Servicer may have entered into, with copies thereof provided to the Master Servicer or the successor servicer if the successor is not the Master Servicer, prior to the Master Servicer or the successor servicer if the successor is not the Master Servicer, assuming such rights and obligations, unless the Master Servicer elects to terminate any Subservicing Agreement in accordance with its terms as provided in Section 3.03.

Upon such assumption, the Master Servicer, its designee or the successor servicer shall be deemed, subject to Section 3.03, to have assumed all of the Servicer’s interest therein and to have replaced the Servicer as a party to each Subservicing Agreement to the same extent as if each Subservicing Agreement had been assigned to the assuming party, except that (i) the Servicer shall not thereby be relieved of any liability or obligations under any Subservicing Agreement that arose before it ceased to be the Servicer and (ii) none of the Trustee, the Depositor, the Master Servicer, the Securities Administrator, their designees or any successor servicer shall be deemed to have assumed any liability or obligation of the Servicer that arose before it ceased to be the Servicer.

The Servicer at its expense shall, upon request of the Master Servicer, its designee or the successor servicer deliver to the assuming party all documents and records relating to the Subservicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by or on behalf of it, and otherwise use its best efforts to effect the orderly and efficient transfer of the Subservicing Agreements to the assuming party.

Section 3.07

Collection of Certain Mortgage Loan Payments. (a) 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 the terms and provisions of any applicable Insurance Policies, 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 and Accepted Servicing Practices, the Servicer may (i) waive any late payment charge or, if applicable, any penalty interest, or (ii) extend the due dates for the Scheduled Payments due on a Mortgage Note for a period of not greater than 180 days; provided, that any extension pursuant to clause (ii) above shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder, except as provided below. In the event of any such arrangement pursuant to clause (ii) above, the Servicer shall make timely advances on such Mortgage Loan during such extension pursuant to Section 4.01 and in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements, subject to Section 4.01(d) pursuant to which the Servicer shall not be required to make any such advances that are Nonrecoverable P&I Advances. 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 the standards set forth in Section 3.01, may also waive, modify or vary any term of such Mortgage Loan (including modifications that would change the Mortgage Rate, forgive the payment of principal or interest, extend the final maturity date of such Mortgage Loan or waive, in whole or in part, a Prepayment Charge), 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 (any and all such waivers, modifications, variances, forgiveness of principal or interest, postponements, or indulgences collectively referred to herein as “Forbearance”); provided, however, that the Servicer’s approval of a modification of a Due Date shall not be considered a modification for purposes of this sentence; provided, further, that the final maturity date of any Mortgage Loan may not be extended beyond the Final Scheduled Distribution Date for the LIBOR Certificates. The Servicer’s analysis supporting any Forbearance and the conclusion that any Forbearance meets the standards of Section 3.01 shall be reflected in writing in the Servicing File or on the Servicer’s servicing records. In addition, notwithstanding the foregoing, the Servicer may also waive (or permit a Subservicer to waive), in whole or in part, a Prepayment Charge if such waiver would, in the Servicer’s judgment, maximize recoveries on the related Mortgage Loan or if such Prepayment Charge is (i) not permitted to be collected by applicable law, or the collection of the Prepayment Charge would be considered “predatory” pursuant to written guidance published by any applicable federal, state or local regulatory authority having jurisdiction over such matters, or (ii) the enforceability of such Prepayment Charge is limited (1) by bankruptcy, insolvency, moratorium, receivership or other similar laws relating to creditors’ rights or (2) due to acceleration in connection with a foreclosure or other involuntary payment. If a Prepayment Charge is waived other than as permitted in this Section 3.07(a), then the Servicer is required to pay the amount of such waived Prepayment Charge, for the benefit of the Holders of the Class P Certificates, by depositing such amount into the Collection Account together with and at the time that the amount prepaid on the related Mortgage Loan is required to be deposited into the Collection Account; provided, however, that the Servicer shall not have an obligation to pay the amount of any uncollected Prepayment Charge if the failure to collect such amount is the direct result of inaccurate or incomplete information on the Mortgage Loan Schedule in effect at such time. The Master Servicer shall have no responsibility for verifying the accuracy of the amount of Prepayment Charges waived or remitted by the Servicer.

(b)

(i)

The Securities Administrator shall establish and maintain the Excess Reserve Fund Account, on behalf of the Class X Certificateholders, to receive any Basis Risk Payment and to secure their limited recourse obligation to pay to the LIBOR Certificateholders Basis Risk Carryover Amounts.

(ii)

On each Distribution Date, the Securities Administrator shall deposit the amount of any Basis Risk Payment for such date into the Excess Reserve Fund Account.

(c)

(i)

On each Distribution Date on which there exists a Basis Risk Carryover Amount on any Class of Certificates, the Securities Administrator shall (1) withdraw from the Distribution Account and deposit in the Excess Reserve Fund Account, as set forth in Section 4.02(a)(iii)(C), the lesser of (x) the Class X Distributable Amount (without regard to the reduction in the definition thereof with respect to the Basis Risk Payment (to the extent remaining after the distributions specified in Sections 4.02(a)(iii)(A) through (E)) and (y) the aggregate Basis Risk Carryover Amounts for such Distribution Date and (2) withdraw from the Excess Reserve Fund Account amounts necessary to pay to such Class or Classes of LIBOR Certificates the Basis Risk Carryover Amount. Such payments shall be allocated to those Classes on a pro rata basis based upon the amount of Basis Risk Carryover Amount owed to each such Class and shall be paid in the priority set forth in Sections 4.02(a)(iii)(D).

(ii)

The Securities Administrator shall account for the Excess Reserve Fund Account as an asset of a grantor trust under subpart E, Part I of subchapter J of the Code and not as an asset of any REMIC created pursuant to this Agreement. The beneficial owners of the Excess Reserve Fund Account are the Class X Certificateholders. For all federal tax purposes, amounts transferred by the Upper Tier REMIC to the Excess Reserve Fund Account shall be treated as distributions by the Securities Administrator to the Class X Certificateholders.

(iii)

Any Basis Risk Carryover Amounts paid by the Securities Administrator to the LIBOR Certificateholders shall be accounted for by the Securities Administrator as amounts paid first to the Holders of the Class X Certificates and then to the respective Class or Classes of LIBOR Certificates. In addition, the Securities Administrator shall account for such Certificateholders’ rights to receive payments of Basis Risk Carryover Amounts as rights in a limited recourse notional principal contract written by the Class X Certificateholders in favor of such Certificateholders.

(iv)

Notwithstanding any provision contained in this Agreement, the Securities Administrator shall not be required to make any payments to and from the Excess Reserve Fund Account except as expressly set forth in this Section 3.07(c) and Sections 4.02(a)(iii)(C) and (D).

(d)

The Securities Administrator shall establish and maintain the Distribution Account on behalf of the Certificateholders. The Master Servicer shall, promptly upon receipt, deposit in the Distribution Account and retain therein the following:

(i)

the aggregate amount remitted by the Servicer to the Master Servicer pursuant to Section 3.11;

(ii)

any amount deposited by the Servicer pursuant to Section 3.12(b) in connection with any losses on Permitted Investments; and

(iii)

any other amounts deposited hereunder which are required to be deposited in the Distribution Account.

In the event that the Servicer shall remit any amount not required to be remitted, it may at any time direct the Securities Administrator in writing to withdraw such amount from the Distribution Account, any provision herein to the contrary notwithstanding. Such direction may be accomplished by delivering notice to the Securities Administrator which describes the amounts deposited in error in the Distribution Account. All funds deposited in the Distribution Account shall be held by the Securities Administrator in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 4.02.

(e)

The Securities Administrator may invest the funds in the Distribution Account during the Securities Administrator Float Period in one or more Permitted Investments in accordance with Section 3.12. The Securities Administrator may withdraw from the Distribution Account any income or gain earned from the investment of funds deposited therein for its own benefit.

(f)

The Servicer shall give notice to the Securities Administrator of any proposed change of the location of the Collection Account not later than 30 days and not more than 45 days prior to any change thereof and the Securities Administrator shall forward such notice to each Rating Agency and the Depositor.

Section 3.08

Subservicing Accounts. In those cases where a Subservicer is servicing a Mortgage Loan pursuant to a Subservicing Agreement, the Subservicer will be required to establish and maintain one or more segregated accounts (collectively, the “Subservicing Account”). The Subservicing Account shall be an Eligible Account and shall otherwise be acceptable to the Servicer. The Subservicer shall deposit in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Subservicer’s receipt thereof, all proceeds of Mortgage Loans received by the Subservicer less its servicing compensation to the extent permitted by the Subservicing Agreement, and shall thereafter deposit such amounts in the Subservicing Account, in no event more than two Business Days after the deposit of such funds into the clearing account. The Subservicer shall thereafter deposit such proceeds in the Collection Account or remit such proceeds to the Servicer for deposit in the Collection Account not later than two Business Days after the deposit of such amounts in the Subservicing Account. For purposes of this Agreement, the Servicer shall be deemed to have received payments on the Mortgage Loans when the Subservicer receives such payments. Funds in the clearing account and any Subservicing Account may, in the discretion of the Servicer, be invested in Permitted Investments pending their desposit into the Subservicing Account and the Collection Account, as applicable; provided, however, the Servicer shall be responsible for any losses incurred on such investments.

Section 3.09

Collection of Taxes, Assessments and Similar Items; Escrow Accounts. To the extent the related Mortgage provides for Escrow Payments, the Servicer shall establish and maintain, or cause to be established and maintained, one or more segregated accounts (the “Escrow Accounts”), which shall be Eligible Accounts. The Servicer shall deposit in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Servicer’s receipt thereof, all collections from the Mortgagors (or related advances from Subservicers) for the payment of taxes, assessments, hazard insurance premiums and comparable items for the account of the Mortgagors (“Escrow Payments”) collected on account of the Mortgage Loans and shall thereafter deposit such Escrow Payments in the Escrow Accounts, in no event more than two Business Days after the deposit of such funds in the clearing account, for the purpose of effecting the payment of any such items as required under the terms of this Agreement. Withdrawals of amounts from an Escrow Account may be made only to (i) effect payment of taxes, assessments, hazard insurance premiums, and comparable items; (ii) reimburse the Servicer (or a Subservicer to the extent provided in the related Subservicing Agreement) out of the collection for any advances made pursuant to Section 3.01 (with respect to taxes and assessments) and Section 3.13 (with respect to hazard insurance); (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest, if required and as described below, to Mortgagors on balances in the Escrow Account; (v) clear and terminate the Escrow Account at the termination of the Servicer’s obligations and responsibilities in respect of the Mortgage Loans under this Agreement; or (vi) recover amounts deposited in error. As part of its servicing duties, the Servicer or Subservicers shall pay to the Mortgagors interest on funds in Escrow Accounts, to the extent required by law and, to the extent that interest earned on funds in the Escrow Accounts is insufficient, to pay such interest from its or their own funds, without any reimbursement therefor. To the extent that a Mortgage does not provide for Escrow Payments, the Servicer shall determine whether any such payments are made by the Mortgagor in a manner and at a time that avoids the loss of the Mortgaged Property due to a tax sale or the foreclosure of a tax lien. The Servicer assumes full responsibility for the payment of all such bills within such time 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 advances from its own funds to effect such payments; provided, however, that such advances are deemed to be Servicing Advances.

Section 3.10

Collection Account. (a) On behalf of the Trustee, the Servicer shall establish and maintain, or cause to be established and maintained, one or more segregated Eligible Accounts (such account or accounts, the “Collection Account”), held in trust for the benefit of the Trustee. On behalf of the Trustee, the Servicer shall deposit or cause to be deposited in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Servicer’s receipt thereof, and shall thereafter deposit into the Collection Account, in no event more than two Business Days after the deposit of such funds into the clearing account, as and when received or as otherwise required hereunder, the following payments and collections received or made by it subsequent to the Cut-off Date (other than in respect of principal or interest on the related Mortgage Loans due on or before the Cut-off Date), or payments (other than Principal Prepayments) 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, on the Mortgage Loans;

(ii)

all payments on account of interest (net of the related Servicing Fee) on each Mortgage Loan;

(iii)

all Insurance Proceeds and Condemnation Proceeds to the extent such Insurance Proceeds and Condemnation Proceeds are not to be applied to the restoration of the related Mortgaged Property or released to the related Mortgagor in accordance with the express requirements of law or in accordance with Accepted Servicing Practices, Liquidation Proceeds and Subsequent Recoveries;

(iv)

any amounts required to be deposited pursuant to Section 3.12 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 3.13(a) in respect of any blanket policy deductibles;

(vi)

all proceeds of any Mortgage Loan repurchased or purchased in accordance with this Agreement; and

(vii)

all Prepayment Charges collected by the Servicer.

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, NSF fees, reconveyance fees, assumption fees and other similar fees and charges need not be deposited by the Servicer in the Collection Account and shall, upon collection, belong to the Servicer as additional compensation for its servicing activities. 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)

Funds in the Collection Account may be invested in Permitted Investments in accordance with the provisions set forth in Section 3.12. The Servicer shall give notice to the Securities Administrator, the Master Servicer, the Trustee and the Depositor of the location of the Collection Account maintained by it when established and prior to any change thereof.

Section 3.11

Withdrawals from the Collection Account. (a) The Servicer shall, from time to time, make withdrawals from the Collection Account maintained by it for any of the following purposes or as described in Section 4.01:

(i)

on or prior to each Remittance Date, to remit to the Master Servicer (A) the Master Servicing Fee with respect to such Distribution Date and (B) all Available Funds in respect of the related Distribution Date together with all amounts representing Prepayment Charges (payable to the Class P Certificateholders) from the Mortgage Loans received during the related Prepayment Period;

(ii)

to reimburse the Servicer for P&I Advances, but only to the extent of amounts received which represent Late Collections (net of the related Servicing Fees) of Scheduled Payments on Mortgage Loans with respect to which such P&I Advances were made by the Servicer in accordance with the provisions of Section 4.01 and (B) any xxxxxxxxxxxx X&X Advances to the extent of funds held in the Collection Account for a future Distribution Date that were not included in Available Funds for the preceding Distribution Date;

(iii)

to pay the Servicer or any Subservicer (A) any unpaid Servicing Fees or (B) any unreimbursed Servicing Advances with respect to each Mortgage Loan, but only to the extent of any Late Collections or other amounts as may be collected by the Servicer from a Mortgagor, or otherwise received with respect to such Mortgage Loan (or the related REO Property);

(iv)

to pay to the Servicer as servicing compensation (in addition to the Servicing Fee) on each Remittance Date any interest or investment income earned on funds deposited in the Collection Account;

(v)

to pay to the Originator, with respect to each Mortgage Loan that has previously been repurchased or replaced pursuant to this Agreement, all amounts received thereon subsequent to the date of purchase or substitution, as the case may be;

(vi)

to reimburse the Servicer for (A) any P&I Advance or Servicing Advance previously made which the Servicer has determined to be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance in accordance with the provisions of Section 4.01 and (B) any unpaid Servicing Fees to the extent not recoverable from Late Collections or other amounts received with respect to the related Mortgage Loan under Section 3.11(a)(iii);

(vii)

to pay, or to reimburse the Servicer for Servicing Advances in respect of, expenses incurred in connection with any Mortgage Loan pursuant to Section 3.15;

(viii)

to reimburse the Master Servicer, the Servicer, the Depositor, the Securities Administrator or the Trustee for expenses incurred by or reimbursable to the Master Servicer, the Servicer, the Depositor, the Securities Administrator or the Trustee, as the case may be, pursuant to Section 6.03, Section 7.02, Section 8.05, Section 9.13 or Section 10.02;

(ix)

to reimburse the Master Servicer, the Servicer or the Trustee, as the case may be, for expenses reasonably incurred in respect of the breach or defect giving rise to the repurchase obligation of the Originator or the Sponsor under this Agreement that were included in the Repurchase Price of the Mortgage Loan, including any expenses arising out of the enforcement of the repurchase obligation, to the extent not otherwise paid pursuant to the terms hereof;

(x)

to withdraw any amounts deposited in the Collection Account in error; and

(xi)

to clear and terminate the Collection Account upon termination of this Agreement.

(b)

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 (a)(ii), (iii), (v), (vi), (vii), (viii) and (ix) above. The Servicer shall provide written notification (as set forth in Section 4.01(d)) to the Master Servicer, on or prior to the next succeeding Remittance Date, upon making any withdrawals from the Collection Account pursuant to subclause (a)(vi) above.

Section 3.12

Investment of Funds in the Collection Account, Escrow Accounts and the Distribution Account. (a) The Servicer may invest the funds in the Collection Account maintained by it and the Escrow Accounts (to the extent permitted by law and the related Mortgage Loan documents) and the Securities Administrator may invest funds in the Distribution Account during the Securities Administrator’s Float Period and shall invest such funds in the Distribution Account (for purposes of this Section 3.12, each such Account is referred to as an “Investment Account”), in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, 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; provided, however, that any such Permitted Investment managed by or advised by the Securities Administrator or any of its Affiliates may mature, unless payable on demand, no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds in an Investment Account shall be made in the name of the Servicer or the Securities Administrator, as applicable. The Servicer or the Securities Administrator, as applicable, shall be entitled to sole possession over each such investment, and any certificate or other instrument evidencing any such investment shall be delivered directly to the Servicer or the Securities Administrator or its agent, as applicable, together with any document of transfer necessary to transfer title to such investment to the Servicer or the Securities Administrator or its agent, as applicable. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand, the Servicer or the Securities Administrator, as applicable, may:

(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 that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in an Investment Account.

(b)

All income and gain realized from the investment of funds deposited in the Collection Account or Escrow Account, as applicable, held by or on behalf of the Servicer, shall be for the benefit of the Servicer and shall be subject to its withdrawal in the manner set forth in Section 3.11. The Servicer shall deposit in the Collection Account or Escrow Account, as applicable, the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon realization of such loss.

(c)

All income and gain realized from the investment of funds deposited in the Distribution Account held by the Securities Administrator during the Securities Administrator’s Float Period, shall be for the benefit of the Securities Administrator, and shall be subject to the Securities Administrator’s withdrawal in the manner set forth in Section 3.07(d). Notwithstanding anything in this Section 3.12(c), the Securities Administrator shall be liable to the Trust for any such loss on any funds it has invested under this Section 3.12(c) only during the Securities Administrator Float Period, and the Securities Administrator shall deposit in the Distribution Account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such account immediately upon realization of such loss.

(d)

Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment of funds held in the Escrow Account or any Collection Account, or if a default occurs in any other performance required under any Permitted Investment of funds held in the Escrow Account or any Collection Account, the Servicer or the Securities Administrator, as applicable, shall take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

(e)

The Securities Administrator or its Affiliates are permitted to receive additional compensation that could be deemed to be in the Securities Administrator’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 for payable pursuant to this Agreement.

Section 3.13

Maintenance of Hazard Insurance and Errors and Omissions and Fidelity Coverage. (a) The Servicer shall cause to be maintained for each Mortgage Loan fire insurance with extended coverage on the related Mortgaged Property in an amount which is at least equal to the least of (i) the outstanding principal balance of such Mortgage Loan, (ii) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis and (iii) the maximum insurable value of the improvements which are a part of such Mortgaged Property, 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 insurance with extended coverage on each REO Property 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 required to be deposited in the Escrow Account and 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 the procedures that the Servicer would follow in servicing loans held for its own account, 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 3.11. Any cost incurred by the Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to the Master Servicer, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of 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 and flood insurance has been made available, 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:VI or better in Best’s (or such other rating that is comparable to such rating) insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first two sentences of this Section 3.13, 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 3.13, 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 and the Trustee, 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 the Servicer’s obligations under this Agreement, which, policy or policies shall be in such form and amounts that would meet the requirements of Xxxxxx Xxx and Xxxxxxx Mac, unless the Servicer has obtained a waiver of such requirements from Xxxxxx Mae and Xxxxxxx Mac. The Servicer shall also maintain a fidelity bond in the form and amounts that would meet the requirements of Xxxxxx Mae and Xxxxxxx Mac, unless the Servicer has obtained a waiver of such requirements from Xxxxxx Mae and Xxxxxxx Mac. The Servicer shall provide the Master Servicer with copies of any such insurance policies and fidelity bond. 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 Master Servicer. The Servicer shall also cause each Subservicer to maintain a policy of insurance covering errors and omissions and a fidelity bond which would meet such requirements.

Section 3.14

Enforcement of Due-On-Sale Clauses; Assumption Agreements. The Servicer will, to the extent it has knowledge of any conveyance or prospective 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 or if the exercise of such rights would impair or threaten to impair recovery under the related Primary Mortgage Insurance Policy, if any. If the Servicer 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 will enter into either (i) 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 or (ii) a substitution agreement as provided in the succeeding sentence. 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 underwriting criteria of the Originator and has a credit risk rating at least equal to that of the original Mortgagor. The Mortgage Loan, as assumed, shall conform in all respects to the requirements, representations and warranties of this Agreement. 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, or a new policy meeting the requirements of this Section is obtained. 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 Scheduled Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The Servicer shall notify the Master Servicer that any such substitution, modification or assumption agreement has been completed and shall forward to 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 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 whatsoever. For purposes of this Section 3.14, 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 3.15

Realization upon Defaulted Mortgage Loans. The Servicer shall use its best efforts, consistent with Accepted Servicing Practices, to foreclose upon or otherwise comparably convert (which may include an acquisition of REO Property) 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 3.07, and which are not released from this Agreement pursuant to any other provision hereof. The Servicer shall use reasonable efforts to realize upon such defaulted Mortgage Loans in such manner as will maximize the receipt of principal and interest by the Securities Administrator, taking into account, among other things, the timing of foreclosure proceedings. The foregoing is subject to the provisions that the Servicer shall not be required to expend its own funds in connection with foreclosure or other conversion, correction of a default on a senior mortgage or restoration of any property unless it shall determine in its sole discretion (i) that such foreclosure, correction or restoration will increase the net Liquidation Proceeds of the related Mortgage Loan to the Securities Administrator, after reimbursement to itself for such expenses and (ii) that such expenses will be recoverable by the Servicer through Insurance Proceeds, Condemnation Proceeds, Liquidation Proceeds or Subsequent Recoveries from the related Mortgaged Property, as contemplated in Section 3.11. The Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the related property, as contemplated in Section 3.11.

The proceeds of any liquidation or REO Disposition, as well as any recovery resulting from a partial collection of Insurance Proceeds, Condemnation Proceeds, Liquidation Proceeds or Subsequent Recoveries or any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Servicer or any Subservicer for any related unreimbursed Servicing Advances, pursuant to Section 3.11 or 3.17; second, to reimburse the Servicer for any related xxxxxxxxxxxx X&X Advances, pursuant to Section 3.11; third, to accrued and unpaid interest on the Mortgage Loan or REO Imputed Interest, at the Mortgage Rate, to the date of the liquidation or REO Disposition, or to the Due Date prior to the Remittance Date on which such amounts are to be distributed if not in connection with a liquidation or REO Disposition; and fourth, as a recovery of principal of the Mortgage Loan. If the amount of the recovery so allocated to interest is less than a full recovery thereof, that amount will be allocated as follows: first, to unpaid Servicing Fees; and second, as interest at the Mortgage Rate (net of the Servicing Fee Rate). The portion of the recovery so allocated to unpaid Servicing Fees shall be reimbursed to the Servicer or any Subservicer pursuant to Section 3.11 or 3.17. The portions of the recovery so allocated to interest at the Mortgage Rate (net of the Servicing Fee Rate) and to principal of the Mortgage Loan shall be applied as follows: first, to reimburse the Servicer or any Subservicer for any related unreimbursed Servicing Advances in accordance with Section 3.11 or 3.17, and second, to the Securities Administrator in accordance with the provisions of Section 4.02, subject to paragraph (e) of Section 3.17 with respect to certain excess recoveries from an REO Disposition.

Notwithstanding anything to the contrary contained herein, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Servicer has received actual notice of, or has actual knowledge of the presence of, hazardous or toxic substances or wastes on the related Mortgaged Property, or if the Trustee or the Master Servicer otherwise requests, the Servicer shall cause an environmental inspection or review of such Mortgaged Property to be conducted by a qualified inspector. Upon completion of the inspection, the Servicer shall promptly provide the Trustee, the Master Servicer and the Depositor with a written report of the environmental inspection.

After reviewing the environmental inspection report, the Servicer shall determine consistent with Accepted Servicing Practices how to proceed with respect to the Mortgaged Property. In the event (a) the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes and (b) the Servicer proceeds with foreclosure or acceptance of a deed in lieu of foreclosure, the Servicer shall be reimbursed for all reasonable costs associated with such foreclosure or acceptance of a deed in lieu of foreclosure and any related environmental clean-up costs, as applicable, from the related Liquidation Proceeds, or if the Liquidation Proceeds are insufficient to fully reimburse the Servicer, the Servicer shall be entitled to be reimbursed from amounts in the Collection Account pursuant to Section 3.11. In the event the Servicer does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure, the Servicer shall be reimbursed from general collections for all Servicing Advances made with respect to the related Mortgaged Property from the Collection Account pursuant to Section 3.11. The Trustee shall not be responsible for any determination made by the Servicer pursuant to this paragraph or otherwise.

Section 3.16

Release of Mortgage Files. (a) Upon the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Servicer will, within five (5) Business Days of the payment in full, notify the Custodian by a certification (which certification shall include a statement to the effect that all amounts received or to be received in connection with such payment which are required to be deposited in the Collection Account pursuant to Section 3.10 have been or will be so deposited) of a Servicing Officer and shall request delivery to it of the Custodial File by submitting a Request for Release, which Request for Release may be in an electronic format in a form acceptable to the Custodian, to the Custodian. Upon receipt of such certification and Request for Release, the Custodian shall promptly release the related Custodial File to the Servicer within five (5) Business Days. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account.

(b)

From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Insurance Policy relating to the Mortgage Loans, the Custodian shall, upon request of the Servicer and delivery to the Custodian of a Request for Release, which Request for Release may be in an electronic format in a form acceptable to the Custodian, release the related Custodial File to the Servicer, and the Custodian shall, at the direction of the Servicer, execute such documents as shall be necessary to the prosecution of any such proceedings and the Servicer shall retain the Mortgage File in trust for the benefit of the Trustee. Such Request for Release shall obligate the Servicer to return each and every document previously requested from the Custodial File to the Custodian when the need therefor by the Servicer no longer exists, unless the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Servicer has delivered to the Custodian a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery. Upon receipt of a certificate of a Servicing Officer stating that such Mortgage Loan was liquidated and that all amounts received or to be received in connection with such liquidation that are required to be deposited into the Collection Account have been so deposited, or that such Mortgage Loan has become an REO Property, a copy of the Request for Release shall be released by the Custodian to the Servicer or its designee.

Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the Servicer copies of any court pleadings, requests for trustee’s sale or other documents reasonably 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, or shall exercise and deliver to the Servicer a power of attorney sufficient to authorize the Servicer to execute such documents on its behalf. 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.

Section 3.17

Title, Conservation and Disposition of REO Property. (a) This Section shall apply only to REO Properties acquired for the account of the Trustee and shall not apply to any REO Property relating to a Mortgage Loan which was purchased or repurchased from the Trustee pursuant to any provision hereof. In the event that title to any such REO Property is acquired, the deed or certificate of sale shall be issued to the Trust, or if not permitted by law, to Deutsche Bank National Trust Company (or, if applicable, the name of the successor Trustee) as Trustee for HSI Asset Securitization Corporation Trust 2006-OPT2 Mortgage Pass-Through Certificates, Series 2006-OPT2, or to its nominee, for the benefit of the Certificateholders.

(b)

The Servicer shall manage, conserve, protect and operate each REO Property for the Trustee solely for the purpose of its prompt disposition and sale. The Servicer, either itself or through an agent selected by the Servicer, shall manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. The Servicer shall attempt to sell the same (and may temporarily rent the same for a period not greater than one year, except as otherwise provided below) on such terms and conditions as the Servicer deems to be in the best interest of the Trustee on behalf of the Certificateholders. The Servicer shall notify the Trustee from time to time as to the status of each REO Property.

(c)

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 deposit such funds in the Collection Account.

(d)

The Servicer shall deposit net of reimbursement to the Servicer for any related outstanding Servicing Advances and unpaid Servicing Fees provided in Section 3.11, or cause to be deposited in the Collection Account, in no event later than two Business Days after the deposit of such funds into the clearing account, all revenues received with respect to the related REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of the REO Property.

(e)

The Servicer, upon an REO Disposition, shall be entitled to reimbursement for any related unreimbursed Servicing Advances as well as any unpaid Servicing Fees from proceeds received in connection with the REO Disposition, as further provided in Section 3.11.

(f)

Any net proceeds from an REO Disposition which are in excess of the unpaid principal balance of the related Mortgage Loan plus all unpaid REO Imputed Interest thereon through the date of the REO Disposition shall be retained by the Servicer as additional servicing compensation.

(g)

The Servicer shall use Accepted Servicing Practices to sell, or cause the Subservicer to sell, in accordance with Accepted Servicing Practices, any REO Property as soon as possible, but in no event later than the conclusion of the third calendar year beginning after the year of its acquisition by the Lower Tier REMIC unless (i) the Servicer applies for an extension of such period from the Internal Revenue Service pursuant to the REMIC Provisions and Code Section 856(e)(3), in which event such REO Property shall be sold within the applicable extension period, or (ii) the Servicer obtains for the Trustee an Opinion of Counsel, addressed to the Depositor, the Trustee and the Servicer, to the effect that the holding by the REMIC of such REO Property subsequent to such period will not result in the imposition of taxes on “prohibited transactions” as defined in Section 860F of the Code or cause any REMIC created under this Agreement to fail to qualify as a REMIC under the REMIC Provisions or comparable provisions of relevant state laws at any time. The Servicer shall manage, conserve, protect and operate each REO Property for the Trustee 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) or result in the receipt by any 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 Section 860G(a)(1) of the Code. Pursuant to its efforts to sell such REO Property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located and may, incident to its conservation and protection of the interests of the Trustee on behalf of the Certificateholders, rent the same, or any part thereof, as the Servicer deems to be in the best interest of the Trustee on behalf of the Certificateholders for the period prior to the sale of such REO Property; provided, however, that any rent received or accrued with respect to such REO Property qualifies as “rents from real property” as defined in Section 856(d) of the Code.

Section 3.18

Notification of Adjustments. With respect to each Adjustable Rate Mortgage Loan, the Servicer shall adjust the Mortgage Rate on the related Adjustment Date and shall adjust the Scheduled Payment on the related mortgage payment adjustment date, if applicable, in compliance with the requirements of applicable law and the related Mortgage and Mortgage Note. In the event that an Index becomes unavailable or otherwise unpublished, the Servicer shall select a comparable alternative index over which it has no direct control and which is readily verifiable. The Servicer shall execute and deliver any and all necessary notices required under applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Rate and Scheduled Payment adjustments. The Servicer shall promptly, upon written request therefor, deliver to the Master Servicer such notifications and any additional applicable data regarding such adjustments and the methods used to calculate and implement such adjustments. Upon the discovery by the Servicer or the receipt of notice from the Master Servicer that the Servicer has failed to adjust a Mortgage Rate or Scheduled Payment in accordance with the terms of the related Mortgage Note, the Servicer shall deposit in the Collection Account from its own funds the amount of any interest loss caused as such interest loss occurs.

Section 3.19

The Servicer shall provide, or cause the Subservicer to provide, to the Depositor, the Trustee, the OTS or the FDIC and the examiners and supervisory agents thereof, access to the documentation regarding the Mortgage Loans in its possession required by applicable regulations of the OTS. Such access shall be afforded without charge, but only upon 10 days (or, if an Event of Default has occurred and is continuing, 3 Business Days) prior written request and during normal business hours at the offices of the Servicer or, if applicable, any Subservicer. Nothing in this Section shall derogate from the obligation of any such party to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of any such party 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 3.19 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 to ship documents to any Person who is not a party to this Agreement, and then only if provisions have been made for the reimbursement of the costs thereof.

Section 3.20

Documents, Records and Funds in Possession of the Servicer to Be Held for the Trustee. Not later than thirty days after each Distribution Date, the Servicer shall forward to the Trustee, the Master Servicer and the Securities Administrator a statement prepared by the Servicer setting forth the status of the Collection Account as of the close of business on the last day of the calendar month relating to 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 3.10(a) and each category of withdrawal specified in Section 3.11. Such statement shall be provided substantially in the form of Exhibit N-1 hereto. 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 the request and at the expense of the requesting party, provided such statement is delivered by the Servicer to the Securities Administrator.

Section 3.21

In addition, the Servicer shall be entitled to recover unpaid Servicing Fees out of related Late Collections and as otherwise permitted under Section 3.11. The right to receive 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 and obligations under this Agreement; provided, however, that the Servicer may pay from the Servicing Fee any amounts due to a Subservicer pursuant to a Subservicing Agreement entered into under Section 3.02.

(b)

Additional servicing compensation in the form of assumption or modification fees, late payment charges, NSF fees, reconveyance fees and other similar fees and charges (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 3.11(a)(iv) to withdraw from the Collection Account, as additional servicing compensation, interest or other income earned on deposits therein. The Servicer shall also be entitled as additional servicing compensation, to interest or other income earned on deposits in the Escrow Account (to the extent permitted by law and the related Mortgage Loan documents) in accordance with Section 3.12. The Servicer shall also be entitled to retain net Prepayment Interest Excesses (to the extent not required to offset Prepayment Interest Shortfalls), but only to the extent such amounts are received by the Servicer.

(c)

The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including payment of premiums for any blanket policy insuring against hazard losses pursuant to Section 3.13, servicing compensation of the Subservicer to the extent not retained by it and the fees and expenses of independent accountants and any agents appointed by the Servicer), and shall not be entitled to reimbursement therefor from the Trust Fund except as specifically provided in Section 3.11.

On each Distribution Date, prior to any distributions on any other Class of Certificates, all amounts representing Prepayment Charges from the Mortgage Loans received during the related Prepayment Period shall be distributed by the Securities Administrator to the holders of the Class P Certificates.

(c)

Any principal distributions to the holders of the Class A Certificates on any Distribution Date prior to the Stepdown Date will be allocated to the Group I Certificates, on the one hand, and the Group II Certificates, on the other hand, based on the Group Principal Allocation Percentage for such Certificate Groups. However, if the Class Certificate Balances of the Class A Certificates in either Certificate Group are reduced to zero before the Stepdown Date, then the remaining amount of principal distributions distributable to the Class A Certificates on that Distribution Date, and the amount of those principal distributions distributable on all subsequent Distribution Dates, will be distributed to the holders of the Class A Certificates in the other Certificate Group remaining outstanding, in accordance with the principal distribution allocations described in this section, until their Class Certificate Balances have been reduced to zero. Any distributions of principal to the Group I Certificates will be made first from payments relating to Group I Mortgage Loans, and any distributions of principal to the Group II Certificates will be made first from payments relating to the Group II Mortgage Loans. If the Class Certificate Balances of the Class A Certificates in either Certificate Group are reduced to zero on or after the Stepdown Date, then the remaining amount of principal distributions distributable to the Class A Certificates on that Distribution Date will be distributed in accordance with Section 4.02(a)(ii)(A)(b). Any principal distributions allocated to the Group II Certificates will be allocated sequentially to the Class II-A-1, Class II-A-2, Class II-A-3 and Class II-A-4 Certificates, in that order, until the Class Certificate Balance of each such Class has been reduced to zero. However, on and after the Distribution Date on which the aggregate Class Certificate Balances of the Class M Certificates been reduced to zero, any principal distributions allocated to the Group II Certificates are required to be allocated pro rata, among the Classes of Group II Certificates, based upon their respective Class Certificate Balances.

(d)

On any Distribution Date, any Relief Act Shortfalls and Net Prepayment Interest Shortfalls for such Distribution Date shall be allocated by the Securities Administrator as a reduction in the following order:

(1)

First, to the amount of interest payable to the Class X Certificates; and

(2)

Second, pro rata, as a reduction of the Interest Payment Amount for the Class A and Class M Certificates, based on the amount of interest to which such Classes would otherwise be entitled.

(e)

On any Distribution Date, the Securities Administrator shall distribute the Supplemental Interest Trust Amount for such date as follows:

(i)

to the Derivative Counterparty, any Net Derivative Payment owed to the Derivative Counterparty pursuant to the Swap Agreement for such Distribution Date to the extent not previously paid in Sections 4.02(a)(i)(A), 4.02(a)(ii)(A) or 4.02(a)(ii)(B);

(ii)

to the Derivative Counterparty, any Swap Termination Payment not due to a Derivative Counterparty Trigger Event owned to the Derivative Counterparty pursuant to the Cap Agreement or the Swap Agreement for such Distribution Date;

(iii)

to the Class A Certificates and the Class M Certificates, the amount necessary to maintain the Overcollateralization Target Amount for such Distribution Date as specified in clause (a)(iii)(A) of this Section 4.02, for application pursuant to the priorities set forth in such clause, after giving effect to distributions pursuant to such clause;

(iv)

to the extent not paid pursuant to clause (a)(iii)(B) of this Section 4.02, sequentially, to the each Class of Class M Certificates, in ascending order by numerical Class designation, first, any Interest Carry Forward Amount for that Class, and second, any Unpaid Realized Loss Amount for that Class;

(v)

to the extent not paid pursuant to clause (a)(iii)(C) of this Section 4.02, to the Excess Reserve Fund Account, the amount of any Basis Risk Payment for such Distribution Date;

(vi)

to the extent not paid pursuant to clause (a)(iii)(D) of this Section 4.02, to the Class A and Class M Certificates, any remaining unpaid Basis Risk Carryover Amount with respect to such Certificates for that Distribution Date, allocated in the same order and priority as set forth in such clause;

(vii)

if applicable, to the Swap Termination Receipts Account or Cap Termination Receipts Account for application to the purchase of a replacement swap agreement or replacement cap agreement pursuant to Section 4.08;

(viii)

to the extent not paid pursuant to clause (a)(iii)(E) of this Section 4.02, to the Derivative Counterparty, any Swap Termination Payment caused by the Derivative Counterparty; and

(ix)

to the extent not paid pursuant to clause (a)(iii)(F) of this Section 4.02, to the holders of the Class X Certificates, the remainder of the Class X Distributable Amount.

With respect to each Distribution Date, the sum of all amounts distributed in priorities (e)(iii) and (e)(iv) second cannot exceed the amount of cumulative Realized Losses incurred up to such Distribution Date minus any distributions made on previous Distribution Dates pursuant to such priorities.

Section 4.03

Monthly Statements to Certificateholders. (a) Not later than each Distribution Date, the Securities Administrator shall make available to each Certificateholder, the Master Servicer, the Servicer, the Depositor, the Trustee and each Rating Agency a statement, based on information provided by the Servicer, setting forth with respect to the related distribution:

(a)

For purposes of preparing the Monthly Statement, delinquencies shall be determined and reported by the Master Servicer based on the so-called “OTS” methodology for determining delinquencies on mortgage loans similar to the Mortgage Loans. By way of example, a Mortgage Loan would be delinquent with respect to a Scheduled Payment due on a Due Date if such Scheduled Payment is not made by the close of business on the Mortgage Loan’s next succeeding Due Date, and a Mortgage Loan would be more than 30-days Delinquent with respect to such Scheduled Payment if such Scheduled Payment were not made by the close of business on the Mortgage Loan’s second succeeding Due Date.

(b)

The Securities Administrator’s responsibility for providing the above statement to the Certificateholders, each Rating Agency, the Master Servicer, the Servicer, the Trustee and the Depositor is limited to the availability, timeliness and accuracy of the information derived from the Master Servicer and the Servicer. The Securities Administrator will provide the above statement via the Securities Administrator’s internet website. The Securities Administrator’s website will initially be located at xxxxx://xxx.xxxxxxx.xxx and assistance in using the website can be obtained by calling the Securities Administrator’s customer service desk at (000) 000-0000. Parties that are unable to use the above distribution method are entitled to have a paper copy mailed to them via first Class mail by calling the customer service desk and indicating such. The Securities Administrator shall have the right to change the manner in which the above statement is distributed in order to make such distribution more convenient and/or more accessible, and the Securities Administrator shall provide timely and adequate notification to the Certificateholders and the parties hereto regarding any such changes. A paper copy of the statement will also be made available upon request.

(c)

Within a reasonable period of time after the end of each calendar year, the Securities Administrator shall, upon request, cause to be furnished to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i), (a)(ii) and (a)(vi) of this Section 4.03 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Securities Administrator shall be deemed to have been satisfied to the extent that substantially comparable information shall have previously been provided by the Securities Administrator pursuant to any requirements of the Code as from time to time in effect.

(d)

On the 10th day of each calendar month (or, if such 10th day is not a Business Day, then on the next succeeding Business Day), the Servicer shall furnish to the Master Servicer (i) a monthly defaulted loan report in the format set forth in Exhibit N-2 hereto and a realized loss report in the format set forth in Exhibit N-3 hereto (or in such other format mutually agreed to between the Servicer and the Master Servicer) relating to the period ending on the last day of the preceding calendar month on a magnetic tape or other similar media reasonably acceptable to the Master Servicer. No later than two Business Days after the fifteenth day of each calendar month, the Servicer shall furnish to the Master Servicer (i) a monthly remittance advice in the format set forth in Exhibit N-1 hereto and a monthly report containing such information regarding prepayments of Mortgage Loans during the applicable Prepayment Period and in a format as mutually agreed to between the Servicer and the Master Servicer and (ii) notice of the occurrence of any material modifications, extensions or waivers of terms, fees, penalties or payments relating to the Mortgage Loans during the related Prepayment Period or that have cumulatively become material over time (see Item 1121(a)(11) of Regulation AB) along with all information, data, and materials related thereto as may be required to be included in the related Distribution Report filed with the Commission on Form 10-D.

Such monthly remittance advice shall also be accompanied by a supplemental report provided to the Master Servicer which includes on an aggregate basis for the previous calendar month (i) the amount of any insurance claims filed, (ii) the amount of any claim payments made and (iii) the amount of claims denied or curtailed. The Master Servicer will convert such data into a format acceptable to the Securities Administrator and provide monthly reports to the Securities Administrator pursuant to this Agreement.

Section 4.04

Certain Matters Relating to the Determination of LIBOR. LIBOR shall be calculated by the Securities Administrator in accordance with the definition of LIBOR. Until all of the LIBOR Certificates are paid in full, the Securities Administrator will at all times retain at least four Reference Banks for the purpose of determining LIBOR with respect to each LIBOR Determination Date. The Securities Administrator initially shall designate the Reference Banks (after consultation with the Depositor). Each “Reference Bank” shall be a leading bank engaged in transactions in Eurodollar deposits in the international Eurocurrency market, shall not control, be controlled by, or be under common control with, the Securities Administrator and shall have an established place of business in London. If any such Reference Bank should be unwilling or unable to act as such or if the Securities Administrator should terminate its appointment as Reference Bank, the Securities Administrator shall promptly appoint or cause to be appointed another Reference Bank (after consultation with the Depositor). The Securities Administrator shall have no liability or responsibility to any Person for (i) the selection of any Reference Bank for purposes of determining LIBOR or (ii) any inability to retain at least four Reference Banks which is caused by circumstances beyond its reasonable control.

The Interest Rate for each Class of LIBOR Certificates for each Interest Accrual Period shall be determined by the Securities Administrator on each LIBOR Determination Date so long as the LIBOR Certificates are outstanding on the basis of LIBOR and the respective formulae appearing in footnotes corresponding to the LIBOR Certificates in the table relating to the Certificates in the Preliminary Statement. The Securities Administrator shall not have any liability or responsibility to any Person for its inability, following a good-faith reasonable effort, to obtain quotations from the Reference Banks or to determine the arithmetic mean referred to in the definition of LIBOR, all as provided for in this Section 4.04 and the definition of LIBOR. The establishment of LIBOR and each Interest Rate for the LIBOR Certificates by the Securities Administrator shall (in the absence of manifest error) be final, conclusive and binding upon each Holder of a Certificate and the Trustee.

Section 4.05

Allocation of Applied Realized Loss Amounts. Any Applied Realized Loss Amounts shall be allocated by the Securities Administrator to the most junior Class of Class M Certificates then outstanding in reduction of the Class Certificate Balance thereof.

Section 4.06

The Swap 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 monies, including, without limitation, other monies of the Securities Administrator held pursuant to this Agreement.

(b)

In addition, the Securities Administrator, acting in its capacity as securities administrator of the Supplemental Interest Trust, shall establish an account (the “Cap Account”), into which the Depositor shall initially deposit $500.

(d)

The Securities Administrator shall deposit into the Cap Account any amounts received from the Cap Counterparty under the Cap Agreement.

(e)

Funds in the Swap Account shall be invested in Permitted Investments constituting time deposits under clause (ii) of the definition thereof. Any earnings on such amounts shall be distributed on each Distribution Date pursuant to Section 4.02(e). The Class X Certificates shall evidence ownership of the Swap Account for federal income tax purposes and the Holder thereof shall direct the Securities Administrator, in writing, as to investment of amounts on deposit therein. The Sponsor shall be liable for any losses incurred on such investments. In the absence of written instructions from the Class X Certificateholders as to investment of funds on deposit in the Swap Account, such funds shall be invested in the Xxxxx Fargo Advantage Prime Investment Money Market Fund or a comparable investment vehicle. Any amounts on deposit in the Swap Account in excess of the Swap Amount on any Distribution Date shall be held for distribution pursuant to Section 4.02(e) on the following Distribution Date.

(f)

Funds in the Cap Account shall be invested in Permitted Investments constituting time deposits under clause (ii) of the definition thereof. Any earnings on such amounts shall be distributed on each Distribution Date pursuant to Section 4.02(e). The Class X Certificates shall evidence ownership of the Cap Account for federal income tax purposes and the Holder thereof shall direct the Securities Administrator, in writing, as to investment of amounts on deposit therein.

(g)

Upon termination of the Trust Fund, any amounts remaining in the Swap Account or the Cap Account shall be distributed pursuant to the priorities set forth in Section 4.02(e).

(h)

It is the intention of the parties hereto that, for federal and state income and state and local franchise tax purposes, the Supplemental Interest Trust be disregarded as an entity separate from the holder of the Class X Certificates unless and until the date when either (a) there is more than one Class X Certificateholder or (b) any Class of Certificates in addition to the Class X Certificates is recharacterized as an equity interest in the Supplemental Interest Trust for federal income tax purposes. Neither the Securities Administrator nor the Trustee shall be responsible for any entity level tax reporting for the Supplemental Interest Trust.

(i)

To the extent that the Supplemental Interest Trust is determined to be a separate legal entity from the Trust, any obligation of the Securities Administrator under the Swap Agreement or Cap Agreement shall be deemed to be an obligation of the Supplemental Interest Trust.

Section 4.07

Rights of the Swap Counterparty. The Swap Counterparty shall be deemed a third-party beneficiary of this Agreement to the same extent as if it were a party hereto and shall have the right, upon designation of an “Early Termination Date” (as defined in the Swap Agreement), to enforce its rights under this Agreement, which rights include but are not limited to the obligation of the Securities Administrator (A) to deposit any Net Derivative Payment required pursuant to Sections 4.02(a)(i)(A), 4.02(a)(ii)(A)(a) and 4.02(a)(ii)(B)(a), and any Swap Termination Payment required pursuant to Sections 4.02(a)(i)(A), 4.02(a)(ii)(A)(a), 4.02(a)(ii)(B)(a) and 4.02(a)(iii)(E), into the Supplemental Interest Trust Account (B) to pay any Net Derivative Payment required pursuant to Section 4.02(e)(i) or Swap Termination Payment required pursuant to Sections 4.02(e)(ii) or Section 4.02(e)(viii), as applicable, to the Swap Counterparty and (C) to establish and maintain the Swap Account, to make such deposits thereto, investments therein and distributions therefrom as are required pursuant to Section 4.06.

Section 4.08

Termination Receipts. (a)(i) In the event of an “Early Termination Event” as defined under the Swap Agreement, (a) any Swap Termination Payment made by the Swap Counterparty to the Swap Account and paid pursuant to Section 4.02(e)(viii) (“Swap Termination Receipts”) will be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Securities Administrator (the “Swap Termination Receipts Account”) and (b) any amounts received from a replacement swap counterparty (“Swap Replacement Receipts”) will be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Securities Administrator (the “Swap Replacement Receipts Account”). The Securities Administrator shall invest, or cause to be invested, funds held in the Swap Termination Receipts Account and the Swap Replacement Receipts Account in time deposits of the Securities Administrator as permitted pursuant to clause (ii) of the definition of Permitted Investments or as otherwise directed in writing by a majority of the Certificateholders. All such Permitted Investments must be payable on demand or mature on a Distribution Date or such other date as directed by the Certificateholders. All such Eligible Investments will be made in the name of the Trustee of the Supplemental Interest Trust (in its capacity as such) or its nominee. All income and gain realized from any such investment shall be deposited in the Termination Receipts Account or the Replacement Receipts Account, as applicable, and all losses, if any, shall be borne by the related account.

(ii)

Amounts on deposit in the Swap Replacement Receipts Account shall be held for the benefit of the related Swap Counterparty and paid to such Swap Counterparty if the Supplemental Interest Trust is required to make a payment to such Swap Counterparty following an event of default or termination event with respect to the Supplemental Interest Trust under the related Swap Agreement. Any amounts not so applied shall, following the termination or expiration of such Swap Agreement, be paid to the Class X Certificates.

(b)

(i) In the event of an “Early Termination Event” as defined under the Cap Agreement, (a) any Cap Termination Payment made by the Cap Counterparty to the Cap Account and paid pursuant to Section 4.02(e)(vii) (“Cap Termination Receipts”) shall be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Securities Administrator (the “Cap Termination Receipts Account”) and (b) any amounts received from a replacement cap counterparty (“Cap Replacement Receipts”) will be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Securities Administrator (the “Cap Replacement Receipts Account”).

ARTICLE V

THE CERTIFICATES

Section 5.01

The Certificates. The Certificates shall be substantially in the forms attached hereto as exhibits. The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount) and aggregate denominations per Class set forth in the Preliminary Statement.

The Depositor hereby directs the Securities Administrator to register the Class X and Class P Certificates in the name of the Depositor or its designee. On a date as to which the Depositor notifies the Securities Administrator, the Securities Administrator shall transfer the Class X and Class P Certificates in the name of the NIM Trustee, or such other name or names as the Depositor shall request, and to deliver the Class X and Class P Certificates to the NIM Trustee or to such other Person or Persons as the Depositor shall request.

Subject to Section 11.02 respecting the final distribution on the Certificates, on each Distribution Date the Securities Administrator shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such holder at a bank or other entity having appropriate facilities therefor, if such Holder has so notified the Securities Administrator at least five Business Days prior to the related Record Date or (y) by check mailed by first Class mail to such Certificateholder at the address of such holder appearing in the Certificate Register; provided, however, so long as such Certificate is a Book-Entry Certificate, all distributions on such Certificate will be made through the Depository or the Depository Participant.

The Certificates shall be executed by manual or facsimile signature on behalf of the Securities Administrator by an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time such signatures were affixed, authorized to sign on behalf of the Securities Administrator shall bind the Securities Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of any 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 authenticated by the Securities Administrator by manual signature, and such authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly executed and delivered hereunder. All Certificates shall be dated the date of their authentication. On the Closing Date, the Securities Administrator shall authenticate the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

Section 5.02

Certificate Register; Registration of Transfer and Exchange of Certificates. (a) The Securities Administrator shall maintain, or cause to be maintained in accordance with the provisions of Section 5.06, a Certificate Register for the Trust Fund in which, subject to the provisions of subsections (b) and (c) below and to such reasonable regulations as it may prescribe, the Securities Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Securities Administrator shall execute and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Securities Administrator. Whenever any Certificates are so surrendered for exchange, the Securities Administrator shall execute, authenticate, and 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 be accompanied by a written instrument of transfer in form satisfactory to the Securities Administrator duly executed by the holder thereof or his attorney duly authorized in writing.

No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but 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 may be required.

All Certificates surrendered for registration of transfer or exchange shall be cancelled and subsequently destroyed by the Securities Administrator in accordance with the Securities Administrator’s customary procedures.

(b)

No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such state securities laws. In determining whether a transfer is being made pursuant to an effective registration statement, the Securities Administrator shall be entitled to rely solely upon a written notice to such effect from the Depositor. Except with respect to (i) the transfer of the Class X, Class P or Class R Certificates to the Depositor or an Affiliate of the Depositor, (ii) the transfer of the Class X or Class P Certificates to the NIM Issuer or the NIM Trustee, or (iii) a transfer of the Class X or Class P Certificates from the NIM Issuer or the NIM Trustee to the Depositor or an Affiliate of the Depositor, in the event that a transfer of a Private Certificate which is a Physical Certificate is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer shall certify to the Securities Administrator in writing the facts surrounding the transfer in substantially the form set forth in Exhibit H (the “Transferor Certificate”) and either (i) there shall be delivered to the Securities Administrator a letter in substantially the form of Exhibit I (the “Rule 144A Letter”) or (ii) there shall be delivered to the Securities Administrator at the expense of the transferor an Opinion of Counsel stating that such transfer may be made without registration under the Securities Act. In the event that a transfer of a Private Certificate which is a Book-Entry Certificate is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer will be deemed to have made as of the transfer date each of the certifications set forth in the Transferor Certificate in respect of such Certificate and the transferee will be deemed to have made as of the transfer date each of the certifications set forth in the Rule 144A Letter in respect of such Certificate, in each case as if such Certificate were evidenced by a Physical Certificate. As directed by the Depositor, the Securities Administrator shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Depositor, the Master Servicer, the Servicer and the Trustee shall cooperate with the Securities Administrator in providing the Rule 144A information referenced in the preceding sentence, including providing to the Securities Administrator such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Securities Administrator shall reasonably determine to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Securities Administrator, the Trustee, the Servicer, the Master Servicer 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.

Except with respect to (i) the transfer of the Class X, Class P or Class R Certificates to the Depositor or an Affiliate of the Depositor, (ii) the transfer of the Class X or Class P Certificates to the NIM Issuer or the NIM Trustee, or (iii) a transfer of the Class X or Class P Certificates from the NIM Issuer or the NIM Trustee to the Depositor or an Affiliate of the Depositor, no transfer of an ERISA-Restricted Certificate shall be made unless the Securities Administrator shall have received either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Securities Administrator (in the event such Certificate is a Private Certificate or a Residual Certificate, such requirement is satisfied only by the Securities Administrator’s receipt of a representation letter from the transferee substantially in the form of Exhibit I), to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA, a plan subject to Section 4975 of the Code or a plan subject to any Federal, state or local law (“Similar Law”) materially similar to the foregoing provisions of ERISA or the Code, nor a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer, or (ii) in the case of an ERISA-Restricted Certificate other than a Residual Certificate, Class X Certificate or a Class P Certificate that has been the subject of an ERISA-Qualifying Underwriting, and the purchaser is an insurance company, a representation that the purchaser is an insurance company that is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption (“PTCE”) 95-60) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate other than a Residual Certificate, Class X Certificate or Class P Certificate presented for registration in the name of an employee benefit plan subject to Title I of ERISA, a plan or arrangement subject to Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a plan subject to Similar Law, or a trustee of any such plan or any other person acting on behalf of any such plan or arrangement or using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Securities Administrator, which Opinion of Counsel shall not be an expense of the Depositor, the Trustee, the Master Servicer, the Servicer, the Securities Administrator or the Trust Fund, addressed to the Securities Administrator, to the effect that the purchase or holding of such ERISA-Restricted Certificate will not constitute or result in a non-exempt prohibited transaction within the meaning of ERISA, Section 4975 of the Code or any Similar Law and will not subject the Trustee, the Depositor, the Securities Administrator, the Master Servicer or the Servicer to any obligation in addition to those expressly undertaken in this Agreement or to any liability. For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Physical Certificate or a Residual Certificate, in the event the representation letter referred to in the preceding sentence is not furnished, such representation shall be deemed to have been made to the Securities Administrator by the transferee’s (including an initial acquirer’s) acceptance of the ERISA-Restricted Certificates. Notwithstanding anything else to the contrary herein, (a) any purported transfer of an ERISA-Restricted Certificate that is a Physical Certificate, other than a Class P Certificate, Class X Certificate or Residual Certificate, to or on behalf of an employee benefit plan subject to ERISA, the Code or Similar Law without the delivery to the Securities Administrator of a representation letter or an Opinion of Counsel satisfactory to the Securities Administrator as described above shall be void and of no effect and (b) any purported transfer of a Class P Certificate, Class X Certificate or Residual Certificate to a transferee that does not make the representation in clause (i) above shall be void and of no effect.

None of the Class R, Class X or Class P Certificates may be sold to any employee benefit plan subject to Title I of ERISA, any plan subject to Section 4975 of the Code, or any plan subject to any Similar Law or any person investing on behalf or with plan assets of such plan.

No transfer of an ERISA-Restriced Derivative Certificate prior to the termination of the Cap Agreement and the Swap Agreement shall be made unless the Securities Administrator shall have received a representation letter from the transferee of such Certificate, substantially in the form set forth in Exhibit I, to the effect that either (i) such transferee is neither an employee benefit plan or arrangement subject to Section 406 of ERISA, a plan subject to Section 4975 of the Code or a plan subject to Similar Law nor a Person acting on behalf of any such Plan or using the assets of any such Plan to effect such transfer or (ii) the acquisition and holding of the ERISA-Restriced Derivative Certificate are eligible for exemptive relief under XXXX 00-00, XXXX 00-0, XXXX 91-38, PTCE 95-60 or PTCE 96-23. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restriced Derivative Certificate prior to the termination of the Cap Agreement and the Swap Agreement on behalf of such Plan without the delivery to the Securities Administrator of a representation letter as described above shall be void and of no effect. If the ERISA-Restriced Derivative Certificate is a Book-Entry Certificate, the transferee will be deemed to have made a representation as provided in clause (i) or (ii) of this paragraph, as applicable.

If any ERISA-Restriced Derivative Certificate, or any interest therein, is acquired or held in violation of the provisions of the preceding paragraph, the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of an ERISA-Restriced Derivative Certificate, or interest therein, was effected in violation of the provisions of the preceding paragraph shall indemnify to the extent permitted by law and hold harmless the Depositor, the Securities Administrator, the Trustee, the Servicer and the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Securities Administrator shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate or ERISA-Restriced Derivative Certificate that is in fact not permitted by this Section 5.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as, in the case of a Physical Certificate, the transfer was registered by the Securities Administrator in accordance with the foregoing requirements.

(c)

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 the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

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;

(ii)

No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Securities Administrator shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Securities Administrator under subparagraph (b) above, the Securities Administrator shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit G;

(iii)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is a Non-Permitted Transferee;

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of 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 Section 5.02(a) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and the Rule 144A Letter. The Securities Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact a Non-Permitted Transferee at the time it became a Holder or, at such subsequent time as it became a Non-Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Securities Administrator shall be paid and delivered by the Securities Administrator to the last preceding Permitted Transferee of such Certificate; and

(v)

The Depositor shall use its best efforts to make available, upon receipt of written request from the Securities Administrator, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is a Non-Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Securities Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Securities Administrator or the Servicer, to the effect that the elimination of such restrictions will not cause any REMIC created hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Securities Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is a Non-Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is a Non-Permitted Transferee to a Holder that is a Permitted Transferee.

(d)

The preparation and delivery of all certificates and opinions referred to above in this Section 5.02 in connection with transfer shall be at the expense of the parties to such transfers.

(e)

Except as provided 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 the 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 Book-Entry Certificates; (iii) ownership and transfers of registration of the Book-Entry 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 deal with the Depository, Depository Participants and indirect participating firms as representatives of the Certificate Owners of the Book-Entry Certificates for purposes of exercising the rights of holders under this Agreement, and requests and directions for and votes of such representatives shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (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.

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 Owner. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures.

If (x) (i) the Depository or the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (ii) the Securities Administrator or the Depositor is unable to locate a qualified successor, or (y) the Depositor notifies the Depository (and the Securities Administrator consents) of its intent to terminate the book-entry system through the Depository and, upon receipt of notice of such intent from the Depository, the Depository Participants holding beneficial interests in the Book-Entry Certificates agree to initiate such termination, the Securities Administrator shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully registered Certificates (the “Definitive Certificates”) to Certificate Owners requesting the same. Upon surrender to the Securities Administrator of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Securities Administrator shall issue the Definitive Certificates. None of the Servicer, the Depositor or the Securities Administrator shall be liable for any delay in delivery of such instruction and each may conclusively rely on, and shall be protected in relying on, such instructions. The Depositor shall provide the Securities Administrator with an adequate inventory of Certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Securities Administrator, to the extent applicable with respect to such Definitive Certificates and the Securities Administrator shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided, that the Securities Administrator shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

(f)

Each Private Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer and accompanied by IRS Form W-8ECI, W-8BEN, W-8IMY (and all appropriate attachments) or W-9 in form satisfactory to the Securities Administrator, duly executed by the Certificateholder or his attorney duly authorized in writing. Each Certificate presented or surrendered for registration of transfer or exchange shall be canceled and subsequently disposed of by the Securities Administrator in accordance with its customary practice. No service charge shall be made for any registration of transfer or exchange of Private 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 Private Certificates.

Section 5.03

Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Depositor, the Securities Administrator and the Trustee such security or indemnity as may be required by them to hold each of them harmless, then, in the absence of notice to the Securities Administrator that such Certificate has been acquired by a bona fide 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 like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 5.03, the Securities Administrator 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) connected therewith. Any replacement Certificate issued pursuant to this Section 5.03 shall constitute complete and indefeasible evidence of ownership, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 5.04

Persons Deemed Owners. The Trustee, the Depositor, the Securities Administrator and any agent of the Trustee, the Depositor or the Securities Administrator may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and neither the Trustee, the Depositor, the Securities Administrator nor any agent of the Trustee, the Depositor or the Securities Administrator shall be affected by any notice to the contrary.

Section 5.05

Access to List of Certificateholders’ Names and Addresses. If three or more Certificateholders (a) request such information in writing from the Securities Administrator, (b) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and (c) provide a copy of the communication which such Certificateholders propose to transmit, or if the Depositor or the Servicer shall request such information in writing from the Securities Administrator, then the Securities Administrator shall, within ten Business Days after the receipt of such request, provide the Depositor, the Servicer or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Securities Administrator, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Securities Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 5.06

The Securities Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange.

On and after the receipt by the Servicer of such written notice, all authority and power of the Servicer hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Master Servicer. Subject to Section 7.02, the Master Servicer is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, 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. Unless expressly provided in such written notice, no such termination shall affect any obligation of the Servicer to pay amounts owed pursuant to Article VIII. The Servicer agrees to cooperate with the Master Servicer in effecting the termination of the Servicer’s responsibilities and rights hereunder, including, without limitation, the transfer to the Master Servicer of all cash amounts which shall at the time be credited to the Collection Account, or thereafter be received with respect to the Mortgage Loans.

Notwithstanding any termination of the activities of the Servicer hereunder, the Servicer shall be entitled to receive from the Trust Fund, prior to transfer of its servicing obligations hereunder, payment of all accrued and unpaid Servicing Fees and reimbursement for all outstanding P&I Advances and Servicing Advances.

Section 7.02

Master Servicer to Act; Appointment of Successor. On and after the time the Servicer receives a notice of termination pursuant to Section 3.25 or Section 7.01, the Master Servicer shall, subject to and to the extent provided in Section 3.05, and subject to the rights of the Master Servicer to appoint a successor servicer pursuant to this Section 7.02, be the successor to the Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof and applicable law including the obligation to make P&I Advances and Servicing Advances, pursuant to Section 3.25 or Section 7.01. It is understood and acknowledged by the parties hereto that there will be a period of transition before the transfer of servicing obligations is fully effective. Notwithstanding the foregoing, the Master Servicer will have a period (not to exceed 90 days) to complete the transfer of all servicing data and correct or manipulate such servicing data as may be required by the Master Servicer to correct any errors or insufficiencies in the servicing data or otherwise enable the Master Servicer to service the Mortgage Loans in accordance with Accepted Servicing Practices. As compensation therefor, the Master Servicer shall be entitled to all funds relating to the Mortgage Loans that the Servicer would have been entitled to charge to the Collection Account if the Servicer had continued to act hereunder including, if the Servicer was receiving the Servicing Fee, the Servicing Fee and the income on investments or gain related to the Collection Account which the Servicer would be entitled to receive. Notwithstanding the foregoing, if the Master Servicer has become the successor to the Servicer in accordance with Section 7.01, the Master Servicer may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making P&I Advances and Servicing Advances pursuant to Section 4.01, if it is otherwise unable to so act or at the written request of Certificateholders entitled to at least a majority of the Voting Rights, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency, as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Any successor to the Servicer shall make the covenant set forth in Section 6.02(b). Any successor to the Servicer shall be an institution which is willing to service the Mortgage Loans and which executes and delivers to the Depositor and the Master Servicer an agreement accepting such delegation and assignment, containing an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer (other than liabilities of the Servicer under Section 6.03 incurred prior to termination of the Servicer under Section 7.01), with like effect as if originally named as a party to this Agreement; provided, that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced, as a result of such assignment and delegation. Pending appointment of a successor to the Servicer hereunder, the Master Servicer, unless the Master Servicer is prohibited by law from so acting, shall, subject to Section 3.05, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Master Servicer may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of the Servicing Fee Rate and amounts paid to the Servicer from investments. The Master Servicer and such successor servicer shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Master Servicer nor any other successor to the 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 Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

Notwithstanding the foregoing, the parties hereto agree that the Master Servicer, in its capacity as successor servicer, immediately shall assume all of the obligations of the Servicer to make Advances and the Master Servicer will assume the other duties of the Servicer as soon as practicable, but in no event later than 90 days after the Master Servicer becomes successor servicer pursuant to the preceding paragraph. Notwithstanding the foregoing, the Master Servicer, in its capacity as successor servicer, shall not be responsible for the lack of information and/or documents that it cannot obtain through reasonable efforts.

In the event that the Servicer is terminated pursuant to Section 7.01, the terminated Servicer shall provide notices to the Mortgagors, transfer the Servicing Files to a successor servicer and pay all of its own out-of-pocket costs and expenses at its own expense. In addition, in the event that the Servicer is terminated pursuant to Section 7.01, the terminated Servicer shall pay all reasonable out-of-pocket costs and expenses of a servicing transfer incurred by parties other than the terminated Servicer promptly upon presentation of reasonable documentation of such costs. If the Master Servicer is the terminated Servicer (except in the case where the Master Servicer in its role as successor servicer is being terminated pursuant to Section 7.01 by reason of an Event of Default caused solely by the Master Servicer as the successor servicer and not by the predecessor Servicer’s actions or omissions), such costs shall be paid by the prior terminated Servicer promptly upon presentation of reasonable documentation of such costs. If the terminated Servicer defaults in its obligation to pay such costs and expenses, the same shall be paid by the successor servicer or the Master Servicer, in which case the successor servicer or the Master Servicer, as applicable, shall be entitled to reimbursement therefor from the Trust Fund.

Any successor to the Servicer as servicer shall give notice to the Mortgagors of such change of servicer and shall, during the term of its service as servicer, maintain in force the policy or policies that the Servicer is required to maintain pursuant to Section 3.13.

Section 7.03

Notification to Certificateholders. (a) Upon any termination of or appointment of a successor to the Servicer, the Securities Administrator shall give prompt written notice thereof to Certificateholders, each Rating Agency and the Derivative Counterparty.

(b)

Within 60 days after the occurrence of any Event of Default, the Securities Administrator shall transmit by mail to all Certificateholders, each Rating Agency and the Derivative Counterparty notice of each such Event of Default hereunder known to the Securities Administrator, unless such event shall have been cured or waived.

ARTICLE VIII

Section 8.01

Duties of the Trustee. The Trustee, before the occurrence of a Master Servicer Event of Default and after the curing of all Master Servicer Events of Default that may have occurred, shall undertake to perform such duties and only such duties as are specifically set forth in this Agreement. In case a Master Servicer Event of Default has occurred and remains uncured, 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 their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b)

the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it is finally proven that the Trustee was negligent in ascertaining the pertinent facts; and

(f)

the Trustee shall not be required to risk or expend its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its rights or powers hereunder if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it;

(g)

the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement;

(h)

(i)

the Trustee shall be under no obligation to exercise any of the trusts, rights 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 this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby; and

(j)

if the Trustee, in its role as successor master servicer under this Agreement, assumes the servicing or master servicing with respect to any of the Mortgage Loans, it shall not assume liability for the representations and warranties of the Servicer or Master Servicer, as applicable, or for any errors or omissions of the Servicer or Master Servicer, as applicable.

The Trustee may also ask for formation documents such as articles of incorporation, an offering memorandum, or other identifying documents to be provided.

Section 8.03

The recitals contained herein and in the Certificates shall be taken as the statements of the Depositor and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Agreement, the Cap Agreement, the Swap Agreement, or of the Certificates or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor, the Master Servicer, the Servicer, the Securities Administrator or the Derivative Counterparty of any funds paid to the Depositor, the Master Servicer, the Servicer, the Securities Administrator or the Derivative Counterparty in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account, the Distribution Account or any other fund or account with respect to the Certificates by the Depositor, the Master Servicer, the Servicer, the Securities Administrator or the Derivative Counterparty.

Section 8.04

Trustee May Own Certificates. The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not the Trustee.

Section 8.05

Trustee’s Fees Indemnification and Expenses. (a) As compensation for its activities under this Agreement, the Trustee shall be paid its fee by the Master Servicer from the Master Servicer’s own funds pursuant to a separate agreement. The Trustee shall have no lien on the Trust Fund for the payment of such fees.

(b)

The Trustee shall be entitled to be reimbursed, from funds on deposit in the Distribution Account, amounts sufficient to indemnify and hold harmless the Trustee and any director, officer, employee, or agent of the Trustee against any loss, liability, or expense (including reasonable attorneys’ fees) incurred in connection with any claim or legal action relating to:

(i)

this Agreement,

(ii)

the Certificates, or

(iii)

the performance of any of the Trustee’s duties under this Agreement,

other than any loss, liability, or expense (i) resulting from any breach of the Servicer’s obligations in connection with this Agreement for which the Servicer has performed its obligation to indemnify the Trustee pursuant to Section 6.05, (ii) resulting from any breach of the Originator’s obligations in connection with this Agreement for which the Originator has performed its obligation to indemnify the Trustee pursuant to Section 2.03(h), (iii) resulting from any breach of the Master Servicer’s obligation hereunder for which the Master Servicer has performed its obligation to indemnify the Trustee pursuant to this Agreement or (iv) incurred because of willful misconduct, bad faith, or negligence in the performance of any of the Trustee’s duties under this Agreement. Without limiting the foregoing, except as otherwise agreed upon in writing by the Depositor and the Trustee, and except for any expense, disbursement, or advance arising from the Trustee’s negligence, bad faith, or willful misconduct, the Trust Fund shall pay or reimburse the Trustee for all reasonable expenses, disbursements, and advances incurred or made by the Trustee in accordance with this Agreement with respect to:

(A)

the reasonable compensation, expenses, and disbursements of its counsel not associated with the closing of the issuance of the Certificates, and

(B)

Except as otherwise provided in this Agreement or a separate letter agreement between the Trustee and the Depositor, the Trustee shall not be entitled to payment or reimbursement for any routine ongoing expenses incurred by the Trustee in the ordinary course of its duties as Trustee under this Agreement or for any other routine expenses incurred by the Trustee; provided, further, that no expense shall be reimbursed hereunder if it would not constitute an “unanticipated expense incurred by the REMIC” within the meaning of the REMIC Provisions.

Section 8.06

Eligibility Requirements for the Trustee. The Trustee hereunder shall at all times be a corporation or association organized and doing business under the laws of a 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, subject to supervision or examination by federal or state authority and with a credit rating which would not cause any of the Rating Agencies to reduce their respective then current ratings of the Certificates (or having provided such security from time to time as is sufficient to avoid such reduction) as evidenced in writing by each Rating Agency. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06 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 condition so published. In case at any time the Trustee shall cease to be eligible in accordance with this Section 8.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.07. The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates, the Master Servicer, the Securities Administrator or the Servicer and its affiliates; provided, however, that such entity cannot be an affiliate of the Depositor or the Servicer other than the Trustee in its role as successor to the Master Servicer.

Section 8.07

Resignation and Removal of the Trustee. The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the Master Servicer, the Securities Administrator and each Rating Agency not less than 60 days before the date specified in such notice, when, subject to Section 8.08, such resignation is to take effect and acceptance by a successor trustee in accordance with Section 8.08 meeting the qualifications set forth in Section 8.06. If no successor trustee meeting such qualifications shall have been so appointed and have accepted appointment within 30 days after the giving of such notice or resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

If at any time the Trustee shall cease to be eligible in accordance with Section 8.06 and shall fail to resign after written request thereto by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Trust Fund is located and the imposition of such tax would be avoided by the appointment of a different trustee, then the Depositor or the Servicer may remove the Trustee and appoint a successor trustee by written instrument, in triplicate, one copy of which shall be delivered to the Trustee, one copy to the Servicer and one copy to the successor trustee.

The Holders of Certificates entitled to at least a majority of the Voting Rights may at any time remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which shall be delivered by the successor Trustee to the Servicer, one complete set to the Trustee so removed and one complete set to the successor so appointed. The successor trustee shall notify each Rating Agency of any removal of the Trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to this Section 8.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.08.

Section 8.08

Successor Trustee. Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and the Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein. The Depositor, the Servicer and the predecessor trustee 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 all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 8.08 unless at the time of its acceptance, the successor trustee is eligible under Section 8.06 and its appointment does not adversely affect then the current rating of the Certificates.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.08, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

Section 8.09

Merger or Consolidation of the Trustee. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder; provided, that such corporation shall be eligible under Section 8.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 8.10

Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Servicer and the Trustee acting jointly 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 the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Servicer and the Trustee may consider appropriate. If the Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(a)

To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee (as successor Master Servicer) under this Agreement to advance funds on behalf of the Master Servicer, shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the 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 the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(b)

No trustee hereunder shall be held personally liable because of any act or omission of any other trustee hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co-trustee as agent of the Trustee;

(c)

The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee; and

(d)

The Trust Fund, and not the Trustee, shall be liable for the payment of reasonable compensation, reimbursement and indemnification to any such separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the separate trustees and co-trustees, when and 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 VIII. Each separate trustee and co-trustee, upon its acceptance of the trusts 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 and indemnity to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Master Servicer and the Depositor.

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.

Section 8.11

Tax Matters. It is intended that the assets with respect to which any REMIC election pertaining to the Trust Fund is to be made, as set forth in the Preliminary Statement, shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Securities Administrator covenants and agrees that it shall act as agent (and the Securities Administrator is hereby appointed to act as agent) on behalf of each REMIC created hereunder and that in such capacity it shall:

(a)

prepare and file in a timely manner, a U.S. Real Estate Mortgage Investment Conduit (REMIC) Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service), which return the Trustee shall sign upon receipt from the Securities Administrator, and the Securities Administrator shall prepare and file with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to each REMIC hereunder containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby;

(b)

within thirty days of the Closing Date, apply for an employer identification number from the Internal Revenue Service via Form SS-4 or any other acceptable method for all tax entities and shall also furnish to the Internal Revenue Service, on Form 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code;

(c)

make an election that each REMIC created hereunder be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law);

(d)

prepare and forward to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including the calculation of any original issue discount using the prepayment assumption (as described in the Prospectus Supplement);

(e)

provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is a Non-Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Non-Permitted Transferee, or a pass-through entity in which a Non-Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax);

(f)

to the extent that they are under its control, conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status of each REMIC created hereunder as a REMIC under the REMIC Provisions;

(g)

not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of any of the REMICs created hereunder;

(h)

pay, from the sources specified in the last paragraph of this Section 8.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on each REMIC created hereunder before its termination when and as the same shall be due and payable (but such obligation shall not prevent the Securities Administrator or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Securities Administrator from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings);

(i)

cause federal, state or local income tax or information returns to be signed by the Securities Administrator or, if required by applicable tax law, the Trustee or such other person as may be required to sign such returns by the Code or state or local laws, regulations or rules; and

(j)

maintain records relating to each REMIC created hereunder, including the income, expenses, assets, and liabilities thereof on a calendar year basis and on the accrual method of accounting and the adjusted basis of the assets determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information.

The Holder of the largest Percentage Interest of the Class R Certificates shall act as Tax Matters Person for each REMIC created hereunder, within the meaning of Treasury Regulations Section 1.860F-4(d), and the Securities Administrator is hereby designated as agent of such Certificateholder for such purpose (or if the Securities Administrator is not so permitted, such Holder shall be the Tax Matters Person in accordance with the REMIC Provisions). In such capacity, the Securities Administrator shall, as and when necessary and appropriate, represent each REMIC created hereunder 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 each REMIC created hereunder, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of each REMIC created hereunder, and otherwise act on behalf of each REMIC in relation to any tax matter or controversy involving it.

The Securities Administrator shall treat the beneficial owners of the Certificates (other than the Class P, Class X and Class R Certificates) as having entered into a notional principal contract with the beneficial owners of the Class X Certificates. Pursuant to each such notional principal contract, all beneficial owners of the LIBOR Certificates shall be treated as having agreed to pay, on each Distribution Date, to the beneficial owners of the Class X Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the interest in the Upper Tier REMIC corresponding to such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class I Shortfall”). A Class I Shortfall payable from interest collections shall be allocated to each Class of Certificates to the extent that interest accrued on such Class for the related Interest Accrual Period at the Interest Rate for a Class, computed by substituting “REMIC 2 Net Funds Cap” for “Group I Available Funds Cap,” “Group II Available Funds Cap,” or “Class M Available Funds Cap,” as applicable in the definition thereof, exceeds the amount of interest accrued for the related Interest Accrual Period based on the applicable Available Funds Cap, and a Class I Shortfall 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 beneficial owner of the Class X Certificates shall be treated as having agreed to pay Basis Risk Carryover Amounts to the Owners of the LIBOR Certificates in accordance with the terms of this Agreement. Any payments to the Certificates in light of the foregoing 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 of a Class I Shortfall shall be treated for tax purposes as having been received by the beneficial owners of such Certificates in respect of their Interests in the Upper Tier REMIC and as having been paid by such beneficial owners to the Supplemental Interest Trust pursuant to the notional principal contract. Thus, each Certificate (other than a Class P and Class R Certificate) shall be treated as representing not only ownership of regular interests in the Upper Tier REMIC, but also ownership of an interest in (and obligations with respect to) a notional principal contract. For tax purposes, the notional principal contract shall be deemed to have a value in favor of the Certificates entitled to receive Basis Risk Carryover Amounts of $10,000 as of the Closing Date.

Notwithstanding the priority and sources of payments set forth in Article IV hereof or otherwise, the Securities Administrator shall account for all distributions on the Certificates as set forth in this Section 8.11. In no event shall any payments of Basis Risk Carryover Amounts provided for in this Section 8.11 be treated as payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1). The Securities Administrator shall file or cause to be filed with the IRS together with Form 1041 or such other form as may be applicable and shall furnish or cause to be furnished, to the Class P Certificateholders, the Class X Certificateholders, the LIBOR Certificateholders, the respective amounts described above that are received, in the time or times and in the manner required by the Code.

To enable the Securities Administrator to perform its duties under this Agreement, the Depositor shall provide to the Securities Administrator within ten days after the Closing Date all information or data that the Securities Administrator requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including the price, yield, prepayment assumption, and projected cash flows of the Certificates and the Mortgage Loans. Moreover, the Depositor shall provide information to the Securities Administrator concerning the value to each Class of Certificates of the right to receive Basis Risk Carryover Amounts from the Excess Reserve Fund Account. Unless otherwise advised by the Depositor, for federal income tax purposes, the Securities Administrator is hereby directed to assign a value of zero to the right of each Holder allocating the purchase price of an initial Offered Certificateholder between such right and the related Upper Tier Regular Interest. Thereafter, the Depositor shall provide to the Securities Administrator promptly upon written request therefor any additional information or data that the Securities Administrator may, from time to time, reasonably request to enable the Securities Administrator to perform its duties under this Agreement; provided, however, that the Depositor shall not be required to provide any information regarding the Mortgage Loans that the Servicer is required to provide to the Securities Administrator pursuant to this Agreement. The Depositor hereby indemnifies the Securities Administrator for any losses, liabilities, damages, claims, or expenses of the Securities Administrator arising from any errors or miscalculations of the Securities Administrator that result from any failure of the Depositor to provide, pursuant to this paragraph, accurate information or data to the Securities Administrator on a timely basis.

None of the Master Servicer, the Securities Administrator or the Trustee shall (i) permit the creation of any interests in any REMIC other than the regular and residual interests set forth in the Preliminary Statement, (ii) receive any amount representing a fee or other compensation for services (except as otherwise permitted by this Agreement or the related Mortgage Loan documents) or (iii) otherwise knowingly or intentionally take any action, cause the Trust Fund to 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, could (i) endanger the status of any REMIC as a REMIC or (ii) result in the imposition of a tax upon any REMIC or 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, or the tax on “net income from foreclosure property”) unless the Securities Administrator receives an Opinion of Counsel (at the expense of the party seeking to take such action or, if such party fails to pay such expense, and the Securities Administrator determines that taking such action is in the best interest of the Trust Fund and the Certificateholders, at the expense of the Trust Fund, but in no event at the expense of the Securities Administrator) to the effect that the contemplated action will not, with respect to the Trust Fund or any REMIC created hereunder, endanger such status or result in the imposition of such a tax).

If any tax is imposed on “prohibited transactions” of a REMIC created hereunder as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of any Lower Tier REMIC as defined in Section 860G(c) of the Code, on any contribution to either of the Lower Tier REMIC or Upper Tier REMIC after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, including any minimum tax imposed on either REMIC pursuant to Sections 23153 and 24874 of the California Revenue and Taxation Code, if not paid as otherwise provided for herein, the tax shall be paid by (i) the Master Servicer, the Trustee, or the Securities Administrator, as applicable, if such tax arises out of or results from negligence of the Master Servicer, the Trustee or the Securities Administrator, as applicable, in the performance of any of its obligations under this Agreement, (ii) the Originator if such tax arises out of or results from the Originator’s obligation to repurchase a Mortgage Loan pursuant to Section 2.03, (iii) the Sponsor, if such tax arises out of or results from the Sponsor’s obligation to repurchase a Mortgage Loan pursuant to Section 2.03(k), (iv) the Servicer, in the case of any such minimum tax, and otherwise if such tax arises out of or results from a breach by the Servicer of any of its obligations under this Agreement, or (v) in all other cases, or if the Master Servicer, the Trustee, the Securities Administrator or the Servicer fails to honor its obligations under the preceding clause (i) or (ii), any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 4.02(a).

Section 8.12

The Securities Administrator shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-D, where such failure results from the Securities Administrator’s inability or failure to receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

(ii)

The Securities Administrator shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-K, where such failure results from the Securities Administrator’s inability or failure to receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

(b)

The Depositor acknowledges and agrees that the Securities Administrator may include in any Exchange Act report all relevant information, data, and exhibits as the Securities Administrator may receive in connection with such report irrespective of any provision or Regulation AB that may permit the exclusion of such material.

(c)

The Depositor agrees to furnish promptly to the Securities Administrator, from time to time upon request, such additional information, data, reports, documents, and financial statements within the Depositor’s possession or control as the Securities Administrator reasonably requests as necessary or appropriate to prepare and file the foregoing reports.

On or before 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 relating to the automatic suspension of reporting in respect of the Trust under the Exchange Act.

(ii) 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 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-DA and 10-KA 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 (to the extent that such amendment is a reportable event) or 10-K needs to be amended, the Securities Administrator will notify the Depositor and such other parties to this Agreement that are affected by this Amendment and such parties will cooperate to prepare any necessary 8-KA, 10-DA or 10-KA.

The Depositor shall be responsible for all costs and expenses of the Securities Administrator related to the preparation and filing of any such amendment. Notwithstanding the foregoing, if any Form 10-D needs to be amended solely to change the information contained in the Monthly Statement, the Securities Administrator shall not be required to notify the Despositor of such amendment.

(e)

Other than the Exchange Act reports specified above, the Securities Administrator shall have no responsibility to file any items or reports with the Commission under the Exchange Act or otherwise; provided, however, the Securities Administrator and Master Servicer will cooperate with the Depositor in connection with any additional filings with respect to the Trust as the Depositor deems necessary under the Exchange Act.

(f)

The Depositor shall pay all costs and expenses of the Securities Administrator related to the preparation and filing of any Current Report on Form 8-K, any Distribution Report on Form 10-D (other than the costs and expense of the Securities Administrator associated with the preparation and filing of the Monthly Statement), or any amendment to any Exchange Act report. Except as otherwise provided herein, all expenses incurred by the Securities Administrator in connection with its preparation and filing of Exchange Act reports hereunder shall not be reimbursable from the Trust.

(g)

Any notice required under this Section 8.12 may be given by facsimile or by electronic mail.

Section 8.13

Tax Classification of the Excess Reserve Fund Account and the Supplemental Interest Trust. For federal income tax purposes, the Securities Administrator shall treat the Excess Reserve Fund Account and the Supplemental Interest Trust as beneficially owned by the holders of the Class X Certificates and shall treat such portion of the Trust Fund as a grantor trust, within the meaning of subpart E, Part I of subchapter J of the Code. The Securities Administrator shall treat the rights that each Class of LIBOR Certificates has to receive payments of Basis Risk Carryover Amounts from the Excess Reserve Fund Account as rights to receive payments under a notional principal contract written by the Class X Certificateholders in favor of each such Class and beneficially owned by each such Class through the grantor trust. Accordingly, each Class of Certificates (excluding the Class X, Class P and Class R Certificates) will be comprised of two components – an Upper Tier REMIC Regular Interest and an interest in a notional principal contract, and the Class X Certificates will be comprised of two components – an Upper Tier REMIC Regular Interest and an interest in the Excess Reserve Fund Account, subject to obligation to pay Basis Risk Carryover Amounts. The Securities Administrator shall allocate the issue price for a Class of Certificates among the respective components for purposes of determining the issue price of the Upper Tier REMIC Regular Interest component based on information received from the Depositor.

Duties of the Master Servicer; Enforcement of Servicer Obligations. (a) The Master Servicer, on behalf of the Trustee, the Securities Administrator, the Depositor and the Certificateholders, shall monitor the performance of the obligations of the Servicer under this Agreement, and (except as set forth below) shall use its reasonable good faith efforts to cause the Servicer to duly and punctually perform its duties and obligations hereunder. Upon the occurrence of an Event of Default of which a Responsible Officer of the Master Servicer has actual knowledge, the Master Servicer shall promptly notify the Securities Administrator and the Trustee and shall specify in such notice the action, if any, the Master Servicer plans to take in respect of such default. So long as an Event of Default shall occur and be continuing, the Master Servicer shall take the actions specified in Article VII.

If (i) the Servicer reports a delinquency on a monthly report and (ii) the Servicer, by 11 a.m. (New York Time) on the related Remittance Date, neither makes an Advance nor provides the Securities Administrator and the Master Servicer with an Officer’s Certificate certifying that such an Advance would be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, then the Master Servicer shall deposit in the Distribution Account not later than the Business Day immediately preceding the related Distribution Date an Advance in an amount equal to the difference between (x) with respect to each Monthly Payment due on a Mortgage Loan that is delinquent (other than Relief Act Interest Shortfalls) and for which the Servicer was required to make an Advance pursuant to this Agreement and (y) amounts deposited in the Collection Account to be used for Advances with respect to such Mortgage Loan, except to the extent the Master Servicer determines any such Advance to be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance. Subject to the foregoing and Section 7.02, the Master Servicer shall continue to make such Advances for so long as the Servicer is required to do so under this Agreement. If applicable, on the Business Day immediately preceding the Distribution Date, the Master Servicer shall deliver an Officer’s Certificate to the Trustee stating that the Master Servicer elects not to make an Advance in a stated amount and detailing the reason(s) it deems the Advance to be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance. Any amounts deposited by the Master Servicer pursuant to this Section 9.01 shall be net of the Servicing Fee for the related Mortgage Loans.

(b)

The Master Servicer shall pay the costs of monitoring the Servicer as required hereunder (including costs associated with (i) termination of the Servicer, (ii) the appointment of a successor servicer or (iii) the transfer to and assumption of, the servicing by the Master Servicer) and shall, to the extent permitted hereunder, seek reimbursement therefor initially from the terminated Servicer. In the event the full costs associated with the transition of servicing responsibilities to the Master Servicer are not paid for by the predecessor or successor servicer (provided such successor servicer is not the Master Servicer), the Master Servicer may be reimbursed therefor by the Trust for all costs incurred by the Master Servicer associated with any such transfer of servicing duties from the Servicer to the Master Servicer or any other successor servicer.

(c)

If the Master Servicer assumes the servicing with respect to any of the Mortgage Loans, it will not assume liability for the representations and warranties of the Servicer it replaces or for any errors or omissions of the Servicer.

(d)

Neither the Depositor nor the Securities Administrator shall consent to the assignment by the Servicer of the Servicer’s rights and obligations under this Agreement without the prior written consent of the Master Servicer, which consent shall not be unreasonably withheld.

Section 9.02

Assessment, Attestation Annual Statement as to Compliance of the Master Servicer. The Master Servicer will deliver or cause to be delivered to the Depositor and the Securities Administrator, on or before March 15^th of each calendar year, commencing in 2007, the assessment of compliance, attestation report and annual statement of compliance required of a Servicing Function Participant under Item 1122 of Regulation AB.

The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

(h)

In each and every such case, so long as a Master Servicer Event of Default shall not have been remedied, in addition to whatever rights the Trustee may have at law or equity to damages, including injunctive relief and specific performance, the Trustee, by notice in writing to the Master Servicer, may, and upon the request of the Holders of Certificates representing at least 51.00% of the Voting Rights shall, terminate with cause all the rights and obligations of the Master Servicer under this Agreement.

Upon receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, shall pass to and be vested in any successor master servicer appointed hereunder which accepts such appointments. Upon written request from the Trustee or the Depositor, the Master Servicer shall prepare, execute and deliver to the successor entity designated by the Trustee any and all documents and other instruments related to the performance of its duties hereunder as the Master Servicer and, place in such successor’s possession all such documents with respect to the master servicing of the Mortgage Loans and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, at the Master Servicer’s sole expense. The Master Servicer shall cooperate with the Trustee and such successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder, including without limitation, the transfer to such successor master servicer for administration by it of all cash amounts which shall at the time be credited to the Distribution Account or are thereafter received with respect to the Mortgage Loans.

Section 9.07

No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

Section 9.08

Successor to the Master Servicer. Upon termination of the Master Servicer’s responsibilities and duties under this Agreement, the Trustee shall appoint a successor, which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Master Servicer under this Agreement prior to the termination of the Master Servicer. Any successor shall be a Xxxxxx Mae and Xxxxxxx Mac approved servicer in good standing and acceptable to the Depositor and the Rating Agencies. In connection with such appointment and assumption, 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; provided, however, that in no event shall the master servicing fee paid to such successor master servicer exceed that paid to the Master Servicer hereunder. In the event that the Master Servicer’s duties, responsibilities and liabilities under this Agreement are terminated, the Master Servicer shall continue to discharge its duties and responsibilities hereunder until the effective date of such termination with the same degree of diligence and prudence which it is obligated to exercise under this Agreement and shall take no action whatsoever that might impair or prejudice the rights of its successor. The termination of the Master Servicer shall not become effective until a successor shall be appointed pursuant hereto and shall in no event (i) relieve the Master Servicer of responsibility for the representations and warranties made pursuant to Section 9.05(a) hereof and the remedies available to the Trustee under Section 9.05(b) hereof, it being understood and agreed that the provisions of Section 9.05 hereof shall be applicable to the Master Servicer notwithstanding any such sale, assignment, resignation or termination of the Master Servicer or the termination of this Agreement; or (ii) affect the right of the Master Servicer to receive payment and/or reimbursement of any amounts accruing to it hereunder prior to the date of termination (or during any transition period in which the Master Servicer continues to perform its duties hereunder prior to the date the successor master servicer fully assumes its duties).

If no successor Master Servicer has accepted its appointment within 90 days of the time the Trustee receives the resignation of the Master Servicer, the Trustee shall be the successor Master Servicer in all respects under this Agreement and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto, including the obligation to make Advances; provided, however, that any failure to perform any duties or responsibilities caused by the Master Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee hereunder. In the Trustee’s capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. Notwithstanding anything herein to the contrary, the Trustee in its role as successor Master Servicer shall have no obligation to monitor or supervise the Servicer, shall only have the obligation to make Advances if it terminates the Servicer pursuant to Section 7.01 (in its role as successor Master Servicer), and shall make such Advances only pursuant to Section 7.02. As compensation therefor, the Trustee shall be entitled to receive the compensation, reimbursement and indemnities otherwise payable to the Master Servicer, including the fees and other amounts payable pursuant to Section 9.09 hereof.

Any successor master servicer appointed as provided herein, shall execute, acknowledge and deliver to the Master Servicer and to the Trustee an instrument accepting such appointment, wherein the successor shall make the representations and warranties set forth in Section 9.05 hereof, and whereupon such successor shall become fully vested with all of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Master Servicer or termination of this Agreement shall not affect any claims that the Trustee may have against the Master Servicer arising out of the Master Servicer’s actions or failure to act prior to any such termination or resignation or in connection with the Trustee’s assumption of such obligations, duties and responsibilities.

Upon a successor’s acceptance of appointment as such, the Master Servicer shall notify by mail the Trustee of such appointment.

Section 9.09

Compensation of the Master Servicer. As compensation for its activities under this Agreement, the Master Servicer shall be paid the Master Servicing Fee.

Section 9.10

Merger or Consolidation. Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer 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 the successor or resulting Person to the Master Servicer shall (i) be a Person (or have an Affiliate) that is qualified and approved to service mortgage loans for Xxxxxx Xxx and Xxxxxxx Mac (provided further that a successor Master Servicer that satisfies subclause (i) through an Affiliate agrees to service the Mortgage Loans in accordance with all applicable Xxxxxx Mae and Xxxxxxx Mac guidelines) and (ii) have a net worth of not less than $25,000,000.

Section 9.11

Resignation of the Master Servicer. Except as otherwise provided in Sections 9.08 and 9.10 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless the Master Servicer’s duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it and cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel that shall be independent to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee shall have assumed, or a successor master servicer satisfactory to the Trustee and the Depositor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Notice of such resignation shall be given promptly by the Master Servicer and the Depositor to the Trustee.

If at any time, Xxxxx Fargo, as Master Servicer, resigns under this Section 9.11, or is removed as Master Servicer pursuant to Section 9.06, then at such time Xxxxx Fargo shall also resign (and shall be entitled to resign) as Securities Administrator under this Agreement.

Section 9.12

Assignment or Delegation of Duties by the Master Servicer. Except as expressly provided herein, the Master Servicer shall not assign or transfer any 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 any of the duties, covenants or obligations to be performed by the Master Servicer; provided, however, that the Master Servicer shall have the right with the prior written consent of the Depositor (which shall not be unreasonably withheld or delayed), and upon delivery to the Trustee and the Depositor of a letter from each Rating Agency to the effect that such action shall not result in a downgrade of the ratings assigned to any of the Certificates, to delegate or assign to or subcontract with or authorize or appoint any qualified Person to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer hereunder. Notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer but in no event shall the fee payable to the successor master servicer exceed that payable to the predecessor master servicer.

Section 9.13

Limitation on Liability of the Master Servicer. Neither the Master Servicer nor any of the directors, officers, employees or agents of the Master Servicer shall be under any liability to the Trustee 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 Master Servicer or any such person against any liability that would otherwise be imposed by reason of willful malfeasance, bad faith or negligence in the performance of its duties or by reason of reckless disregard for its obligations and duties under this Agreement. The Master Servicer and any director, officer, employee or agent of the Master Servicer may rely in good faith on any document prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Master Servicer shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties as Master Servicer with respect to the Mortgage Loans under this Agreement and that in its opinion may involve it in any expenses or liability; provided, however, that the Master Servicer may in its sole discretion undertake any such action that it may deem necessary or desirable in 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, shall be liabilities of the Trust, and the Master Servicer shall be entitled to be reimbursed therefor out of the Distribution Account in accordance with the provisions of Section 9.09 and Section 9.14.

The Master Servicer shall not be liable under this Agreement for any acts or omissions of the Servicer except to the extent that damages or expenses are incurred as a result of such act or omissions and such damages and expenses would not have been incurred but for the negligence, willful malfeasance, bad faith or recklessness of the Master Servicer in supervising, monitoring and overseeing the performance of the obligations of the Servicer as required under this Agreement.

Section 9.14

Indemnification; Third Party Claims. The Master Servicer agrees to indemnify the Depositor, the Servicer, Securities Administrator, the Trustee, and the Trust and hold them harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liability, fees and expenses that the Depositor, the Securities Administrator, the Trustee or the Trust may sustain as a result of the Master Servicer’s (a) willful malfeasance, bad faith or negligence in the performance of its duties hereunder, (b) reckless disregard for its obligations and duties under this Agreement or (c) failure to provide the assessment, attestation and annual statement of compliance in accordance with Section 9.02. The Depositor, the Servicer, the Securities Administrator and the Trustee shall immediately notify the Master Servicer if a claim is made by a third party with respect to this Agreement or the Mortgage Loans which would entitle the Depositor, the Servicer, the Securities Administrator, the Trustee or the Trust to indemnification under this Section 9.14, whereupon the Master Servicer shall assume the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim.

The Master Servicer agrees to indemnify and hold harmless the Trustee from and against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liability, fees and expenses (including reasonable attorneys’ fees) that the Trustee may sustain as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (not including the Trustee’s performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities under such agreement.

The Trust will indemnify the Master Servicer and hold it harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses that the Master Servicer may incur or sustain in connection with, arising out of or related to this Agreement or the Certificates, except to the extent that any such loss, liability or expense is related to (i) a material breach of the Master Servicer’s representations and warranties in this Agreement, (ii) the Master Servicer’s willful malfeasance, bad faith or negligence or by reason of its reckless disregard of its duties and obligations under this Agreement or (iii) failure to provide the assessment, attestation and annual statement of compliance in accordance with Section 9.02; provided that any such loss, liability or expense constitutes an “unanticipated expense incurred by the REMIC” within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii). The Master Servicer shall be entitled to reimbursement for any such indemnified amount from funds on deposit in the Distribution Account.

If at any time, Xxxxx Fargo, as Securities Administrator, resigns under this Section 10.07, or is removed as Securities Administrator pursuant to this Section 10.07, then at such time Xxxxx Fargo shall also resign (and shall be entitled to resign) as Master Servicer under this Agreement.

Section 10.08

Successor Securities Administrator. Any successor securities administrator (which may be the Trustee) appointed as provided in Section 10.07 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor Securities Administrator and the Trustee an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor Securities Administrator shall become effective and such 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 Securities Administrator herein. The Depositor, the Trustee, the Master Servicer and the 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 securities administrator all such rights, powers, duties, and obligations.

No successor securities administrator shall accept appointment as provided in this Section 10.08 unless at the time of such acceptance such successor securities administrator shall be eligible under the provisions of Section 10.06 hereof and its appointment shall not adversely affect then current rating of the Certificates, as confirmed in writing by each Rating Agency.

Upon acceptance by a successor securities administrator of appointment as provided in this Section 10.08, the Depositor shall mail notice of the succession of such Securities Administrator hereunder to all Holders of Certificates. If the Depositor fails to mail such notice within 10 days after acceptance by the successor securities administrator of appointment, the successor securities administrator shall cause such notice to be mailed at the expense of the Depositor.

Any corporation or other entity into which the Securities Administrator may be merged or converted or with which it may be consolidated or any corporation or other entity resulting from any merger, conversion or consolidation to which the Securities Administrator shall be a party, or any corporation or other entity succeeding to the business of the Securities Administrator, shall be the successor of the Securities Administrator hereunder, provided that such corporation or other entity shall be eligible under the provisions of Section 10.06 hereof, without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 10.10

Assignment or Delegation of Duties by the Securities Administrator. Except as expressly provided herein, the Securities Administrator shall not assign or transfer any 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 any of the duties, covenants or obligations to be performed by the Securities Administrator; provided, however, that the Securities Administrator shall have the right with the prior written consent of the Depositor (which shall not be unreasonably withheld or delayed), and upon delivery to the Trustee and the Depositor of a letter from each Rating Agency to the effect that such action shall not result in a downgrade of the ratings assigned to any of the Certificates, to delegate or assign to or subcontract with or authorize or appoint any qualified Person to perform and carry out any duties, covenants or obligations to be performed and carried out by the Securities Administrator hereunder. Notice of such permitted assignment shall be given promptly by the Securities Administrator to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Securities Administrator are transferred to a successor securities administrator, the entire compensation payable to the Securities Administrator pursuant hereto shall thereafter be payable to such successor securities administrator but in no event shall the fee payable to the successor securities administrator exceed that payable to the predecessor securities administrator.

ARTICLE XI

TERMINATION

Section 11.01

Termination upon Liquidation or Purchase of the Mortgage Loans. Subject to Section 11.03, the obligations and responsibilities of the Depositor, the Master Servicer, the Servicer, the Securities Administrator and the Trustee created hereby with respect to the Trust Fund shall terminate upon the earlier of (a) the exercise of an Option to Purchase, on or after the Optional Termination Date, in the aggregate of all Mortgage Loans (and REO Properties) at the price (the “Termination Price”) equal to the sum of (i) 100.00% of the unpaid principal balance of each Mortgage Loan (other than in respect of REO Property) plus accrued and unpaid interest thereon at the applicable Mortgage Rate, (ii) the lesser of (x) the appraised value of any REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Servicer at the expense of that Trust Fund and (y) the unpaid principal balance of each Mortgage Loan related to any REO Property, in each case plus accrued and unpaid interest thereon at the applicable Mortgage Rate, (iii) all xxxxxxxxxxxx X&X Advances, Servicing Advances and indemnification payments payable to the Servicer (iv) any unreimbursed indemnification payments payable to the Trustee, the Securities Administrator, the Master Servicer or the Depositor under this Agreement and (v) any Swap Termination Payments payable to the Swap Counterparty as a result of a termination pursuant to this Section 11.01 and (b) the later of (i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement. In no event shall the trusts created hereby continue beyond the expiration of 21 years from the death of the survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof.

Notwithstanding anything to the contrary contained herein, no such purchase by the Master Servicer (either upon instruction from the Depositor or voluntarily) shall be permitted unless (i) after distribution of the proceeds thereof to the Certificateholders (other than the Holders of the Class X, Class P and Residual Certificates and any other Classes of Certificates which constitute NIM Securities) pursuant to Section 11.02, the distribution of the remaining proceeds to the Class X and Class P Certificates is sufficient to pay the outstanding principal amount of and accrued and unpaid interest on the NIM Securities, to the extent the NIM Securities are then outstanding, or (ii) prior to such purchase, the Master Servicer, remits to the Securities Administrator an amount that, together with such remaining proceeds, will be sufficient to pay the outstanding principal amount of, and accrued and unpaid interest on, the NIM Securities, to the extent the NIM Securities are then outstanding.

Section 11.02

Final Distribution on the Certificates. If on any Remittance Date, the Master Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in any Collection Account, the Master Servicer shall direct the Securities Administrator promptly to send a Notice of Final Distribution to each Certificateholder and to the Swap Counterparty. If the Master Servicer (upon instruction from the Depositor or voluntarily) elects to exercise their option to purchase the Mortgage Loans pursuant to clause (a) of Section 11.01, at least 20 days prior to the date the Notice of Final Distribution is to be mailed to the affected Certificateholders, the Master Servicer shall notify the Depositor, the Swap Counterparty and the Securities Administrator of (a) the date on which the Servicer intends to exercise such purchase option and (b) the Termination Price.

A Notice of Final Distribution, specifying the Distribution Date on which Certificateholders may surrender their Certificates for payment of the final distribution and cancellation, shall be given promptly by the Securities Administrator by letter to Certificateholders mailed not earlier than the 10th day and not later than the 15th day of the month of such final distribution. Any such Notice of Final Distribution shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made and (d) 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 therein specified. The Securities Administrator will give such Notice of Final Distribution to the Swap Counterparty and to each Rating Agency at the time such Notice of Final Distribution is given to Certificateholders.

In the event such Notice of Final Distribution is given, the Servicer shall cause all funds in the Collection Account to be remitted to the Master Servicer for deposit in the Distribution Account on the Business Day prior to the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon such final deposit with respect to the Trust Fund and the receipt by the Custodian of a Request for Release therefor, the Custodian shall promptly release to the Servicer the Custodial Files for the Mortgage Loans.

Upon presentation and surrender of the Certificates, the Securities Administrator shall cause to be distributed to the Certificateholders of each Class (after reimbursement of all amounts due to the Servicer, the Master Servicer, the Securities Administrator, the Depositor, the Trustee and the Swap Counterparty hereunder), in each case on the final Distribution Date and in the order set forth in Section 4.02, in proportion to their respective Percentage Interests, with respect to Certificateholders of the same Class, up to an amount equal to (i) as to each Class of Regular Certificates (except the Class X Certificates), the Certificate Balance thereof plus for each such Class and the Class X Certificates accrued interest thereon in the case of an interest-bearing Certificate and all other amounts to which such Classes are entitled pursuant to Section 4.02 and (ii) as to the Residual Certificates, the amount, if any, which remains on deposit in the Distribution Account (other than the amounts retained to meet claims) after application pursuant to clause (i) above.

In the event that any affected Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the Notice of Final Distribution, the Securities Administrator 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 six months after such second notice all the applicable Certificates shall not have been surrendered for cancellation, the Securities Administrator may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain a part of the Trust Fund. If within one year after the second notice all Certificates shall not have been surrendered for cancellation, the Class R Certificateholders shall be entitled to all unclaimed funds and other assets of the Trust Fund which remain subject hereto.

Section 11.03

Additional Termination Requirements. In the event an Option to Purchase is exercised with respect to the Mortgage Loans as provided in Section 11.01, the Trust Fund shall be terminated in accordance with the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the party upon whose instruction causes the exercise of an Option to Purchase, to the effect that the failure to comply with the requirements of this Section 11.03 will not (i) result in the imposition of taxes on “prohibited transactions” on either the Lower Tier REMIC or the Upper Tier REMIC as defined in Section 860F of the Code or (ii) cause either the Lower Tier REMIC or the Upper Tier REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(a)

The Securities Administrator on behalf of the Trustee shall sell all of the assets of the Trust Fund to the party exercising the Option to Purchase, and, within 90 days of such sale, shall distribute to the Certificateholders the proceeds of such sale in complete liquidation of each of the Lower Tier REMIC and the Upper Tier REMIC; and

(b)

The Securities Administrator shall attach a statement to the final federal income tax return for each of the Lower Tier REMIC and the Upper Tier REMIC stating that pursuant to Treasury Regulations Section 1.860F-1, the first day of the 90-day liquidation period for each such REMIC was the date on which the Securities Administrator on behalf of the Trustee sold the assets of the Trust Fund to the Servicer.

ARTICLE XII

MISCELLANEOUS PROVISIONS

Section 12.01

Amendment. This Agreement may be amended from time to time by the Depositor, the Originator, the Master Servicer, the Servicer, the Securities Administrator and the Trustee, without the consent of any of the Certificateholders or the Derivative Counterparty (except to the extent that the rights or obligations of the Derivative Counterparty under the Cap Agreement or the Swap Agreement are affected thereby, and except to the extent that the ability of the Securities Administrator to perform fully and timely its obligations under the Cap Agreement or the Swap Agreement is adversely affected, in which case prior written consent of the Derivative Counterparty is required) (i) to cure any ambiguity or mistake, (ii) to correct any defective provision herein or to supplement any provision herein which may be inconsistent with any other provision herein, (iii) to add to the duties of the Depositor, the Master Servicer, the Servicer, the Securities Administrator or the Trustee, (iv) to add any other provisions with respect to matters or questions arising hereunder or (v) to modify, alter, amend, add to or rescind any of the terms or provisions contained in this Agreement; provided, that any action pursuant to clause (iv) or (v) above shall not, as evidenced by an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Trustee, the Master Servicer, the Securities Administrator or the Trust Fund), adversely affect in any material respect the interests of any Certificateholder; provided, further, that any such action pursuant to clause (iv) or (v) above shall not be deemed to adversely affect in any material respect the interests of the Certificateholders if the Person requesting the amendment obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates; it being understood and agreed that any such letter in and of itself will not represent a determination as to the materiality of any such amendment and will represent a determination only as to the credit issues affecting any such rating. The Trustee, the Depositor, the Master Servicer, the Originator, the Servicer and the Securities Administrator also may at any time and from time to time amend this Agreement, but without the consent of the Certificateholders or the Derivative Counterparty (except to the extent that the rights or obligations of the Derivative Counterparty hereunder or under the Cap Agreement or the Swap Agreement are affected thereby, and except to the extent that the ability of the Securities Administrator to perform fully and timely its obligations under the Cap Agreement or the Swap Agreement is adversely affected, in which case prior written consent of the Derivative Counterparty is required) to modify, eliminate or add to any of its provisions to such extent as shall be necessary or helpful to (i) maintain the qualification of each REMIC created hereunder under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC created hereunder pursuant to the Code that would be a claim at any time prior to the final redemption of the Certificates or (iii) comply with any other requirements of the Code; provided, that the Trustee and the Master Servicer have been provided an Opinion of Counsel, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee or the Trust Fund, to the effect that such action is necessary or helpful to, as applicable, (i) maintain such qualification, (ii) avoid or minimize the risk of the imposition of such a tax or (iii) comply with any such requirements of the Code.

This Agreement may also be amended from time to time by the Depositor, the Master Servicer, the Servicer, the Originator, the Securities Administrator and the Trustee, but with the consent of the Holders of Certificates evidencing Percentage Interests aggregating not less than 66 2/3% of each Class of Certificates affected thereby 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 required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in clause (i), without the consent of the Holders of Certificates of such Class evidencing, as to such Class, Percentage Interests aggregating not less than 66 2/3%, (iii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all such Certificates then outstanding or (iv) adversely affect the rights or obligations of the Derivative Counterparty hereunder or under the Cap Agreement or the Swap Agreement or the rights of the Securities Administrator to fully and timely perform its obligations under the Cap Agreement or the Swap Agreement without obtaining the prior written consent of the Derivative Counterparty.

Notwithstanding any contrary provision of this Agreement, the Trustee and the Master Servicer shall not consent to any amendment to this Agreement unless (i) it shall have first received an Opinion of Counsel, which opinion shall not be an expense of the Trustee, the Master Servicer or the Trust Fund, to the effect that such amendment will not cause the imposition of any tax on any REMIC created hereunder or the Certificateholders or cause any such REMIC to fail to qualify as a REMIC or the grantor trust to fail to qualify as a grantor trust at any time that any Certificates are outstanding and (ii) the party seeking such amendment shall have provided written notice to the Rating Agencies (with a copy of such notice to the Trustee and the Master Servicer) of such amendment, stating the provisions of the Agreement to be amended.

Notwithstanding the foregoing provisions of this Section 12.01, with respect to any amendment that significantly modifies the permitted activities of the Trustee or the Servicer, any Certificate beneficially owned by the Depositor shall be deemed not to be outstanding (and shall not be considered when determining the percentage of Certificateholders consenting or when calculating the total number of Certificates entitled to consent) for purposes of determining if the requisite consents of Certificateholders under this Section 12.01 have been obtained.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance or a copy of such amendment to each Certificateholder and each Rating Agency.

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.

Nothing in this Agreement shall require the Trustee, the Master Servicer or the Securities Administrator to enter into an amendment without receiving an Opinion of Counsel (which opinion shall not be an expense of the Trustee, the Master Servicer, the Securities Administrator or the Trust Fund), satisfactory to the Trustee, the Master Servicer and the Securities Administrator, as applicable, that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or (B) the conclusion set forth in the immediately preceding clause (A) is not required to be reached pursuant to this Section 12.01.

Notwithstanding the foregoing, the consent of Originator shall not be required to enter into any amendment to this Agreement unless the effect of such amendment would potentially have a material and adverse effect on the rights or obligations of the originator under this Agreement.

Section 12.02

Recordation of Agreement; Counterparts. 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 Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Servicer at the direction and expense of the Depositor, but only upon receipt of an Opinion of Counsel 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

Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 12.04

Intention of Parties. (a) It is intended that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan. However, if such conveyance is deemed to be in respect of a loan, it is intended that: (1) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the benefit of the Holders of the Certificates a first priority security interest to secure repayment of an obligation in an amount equal to the aggregate Class Principal Amount of the Certificates in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and the Supplemental Interest Trust and all proceeds of any and all property constituting the Trust Fund and the Supplemental Interest Trust to secure payment of the Certificates (such security interest being, to the extent of the assets that constitute the Supplemental Interest Trust, pari passu with the security interest as provided in clause (4) below); (3) this Agreement shall constitute a security agreement under applicable law; and (4) the Derivative Counterparty shall be deemed, during the term of such agreement and while such agreement is the property of the Trustee, to have a security interest in all of the assets that constitute the Supplemental Interest Trust, but only to the extent of such Derivative Counterparty’s right to payment under the Derivative Agreements (such security interest being pari passu with the security interest as provided in clause (2) above). If such conveyance is deemed to be in respect of a loan and the trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed by the Securities Administrator as herein provided.

(b)

The Depositor shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority under applicable law and shall be maintained as such throughout the term of this Agreement. The Depositor shall, at its own expense, make all initial filings on or about the Closing Date and shall forward a copy of such filing or filings to the Trustee. Without limiting the generality of the foregoing, the Depositor shall prepare and forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of the Sponsor, the Depositor or the Trustee, (2) any change of location of the jurisdiction of organization of the Sponsor or the Depositor, (3) any transfer of any interest of the Sponsor or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws. Neither the Sponsor nor the Depositor shall organize under the law of any jurisdiction other than the State under which each is organized as of the Closing Date (whether changing its jurisdiction of organization or organizing under an additional jurisdiction) without giving 30 days prior written notice of such action to its immediate and intermediate transferee, including the Trustee. Before effecting such change, the Sponsor or the Depositor proposing to change its jurisdiction of organization shall prepare and file in the appropriate filing office any financing statements or other statements necessary to continue the perfection of the interests of its immediate and intermediate transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, each of the Sponsor and the Depositor authorizes its immediate or intermediate transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b).

Section 12.05

Notices. (a) The Securities Administrator shall use its best efforts to promptly provide notice to each Rating Agency with respect to each of the following of which it has actual knowledge:

Any material change or amendment to this Agreement;

The occurrence of any Event of Default that has not been cured;

The resignation or termination of the Servicer, the Master Servicer, the Securities Administrator or the Trustee and the appointment of any successor;

The repurchase or substitution of Mortgage Loans pursuant to Section 2.03; and

The final payment to Certificateholders.

(b)

In addition, the Securities Administrator shall promptly make available on its internet website to each Rating Agency copies of the following:

Each report to Certificateholders described in Section 4.03; and

No Certificateholder shall have any right to vote (except as provided 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 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 party 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 or by availing itself of any provisions 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 an Event of Default and of the continuance thereof, as herein provided, and unless the Holders of Certificates evidencing not less than 25.00% of the Voting Rights evidenced by the Certificates shall also have made written request to 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 60 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 being understood and intended, and being 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 whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the 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 common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.08, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

(6)

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. Each Prepayment Charge or penalty with respect to any Mortgage Loan is permissible, enforceable and collectible under applicable federal, state and local law;

(7)

All buildings upon the Mortgaged Property are insured by an insurer acceptable to Xxxxxx Xxx and Xxxxxxx 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, in an amount not less than the greatest of (i) 100.00% of the replacement cost of all improvements to the Mortgaged Property, (ii) either (A) the outstanding principal balance of the Mortgage Loan with respect to each first lien Mortgage Loan or (B) with respect to each second lien Mortgage Loan, the sum of the outstanding principal balance of the related first lien mortgage loan and the outstanding principal balance of the second lien Mortgage Loan, (iii) the amount necessary to avoid the operation of any co-insurance provisions with respect to the Mortgaged Property, and consistent with the amount that would have been required as of the date of origination in accordance with the underwriting guidelines or (iv) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis.

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;

Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates a valid, existing and enforceable first or second lien and first or second priority security interest (in each case, as indicated on the Mortgage Loan Schedule) on the property described therein and the Originator has full right to sell and assign the same to the Sponsor. 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 instrument creating a lien subordinate to the lien of the Mortgage;

No claims have been made under such lender’s title insurance policy, and no prior holder of the related Mortgage, including the Originator, has done, by act or omission, anything which would impair the coverage of such lender’s title insurance policy;

With respect to each Mortgage Loan which is not a negative amortization Loan, the Mortgage Note is payable on the first day of each month in Scheduled Payments, which, in the case of Fixed Rate Mortgage Loans, are sufficient to fully amortize the original principal balance over the original term thereof (other than with respect to a Mortgage Loan identified on the related Mortgage Loan Schedule as an interest-only Mortgage Loan during the interest-only period or a Mortgage Loan which is identified on the related Mortgage Loan Schedule as a Balloon Mortgage Loan) and to pay interest at the related Mortgage Rate, and, in the case of an Adjustable Rate Mortgage Loan, are changed on each Adjustment Date, and in any case, are sufficient to fully amortize the original principal balance over the original term thereof (other than with respect to a Mortgage Loan identified on the related Mortgage Loan Schedule as an interest-only Mortgage Loan during the interest-only period or a Mortgage Loan which is identified on the related Mortgage Loan Schedule as a Balloon Mortgage Loan) and to pay interest at the related Mortgage Rate.

With respect to each Mortgage Loan identified on the Mortgage Loan Schedule as an interest-only Mortgage Loan, the interest-only period shall not exceed ten (10) years (or such other period specified on the Mortgage Loan Schedule) and following the expiration of such interest-only period, the remaining Scheduled Payments shall be sufficient to fully amortize the original principal balance over the remaining term of the Mortgage Loan. With respect to each Balloon Mortgage Loan, the Mortgage Note requires a monthly payment which is sufficient to fully amortize the original principal balance over the original term thereof and to pay interest at the related Mortgage Rate and requires a final Scheduled Payment substantially greater than the preceding monthly payment which is sufficient to repay the remained unpaid principal balance of the Balloon Mortgage Loan as the Due Date of such monthly payment. The Index for each Adjustable Rate Mortgage Loan is as defined in the related Confirmation. No Mortgage Loan is a Convertible Mortgage Loan;

(22)

The origination, servicing and collection practices used by the Originator with respect to each Mortgage Note and Mortgage including, without limitation, the establishment, maintenance and servicing of the Escrow Accounts and Escrow Payments, if any, since origination, have been in all respects legal, proper, prudent and customary in the mortgage origination and servicing industry.

No proceeds from any Mortgage Loan were used to purchase single premium credit insurance policies as part of the origination of, or as a condition to closing, such Mortgage Loan;

(48)

The Mortgage Loans were not selected from the outstanding fixed rate or adjustable rate one to four-family mortgage loans in the Originator’s portfolio at the related Initial Sale Date as to which the representations and warranties set forth in this Agreement could be made in a manner so as to affect adversely the interests of the Sponsor;

(49)

The Mortgage contains an enforceable provision for the acceleration of the payment of the unpaid principal balance of the Mortgage Loan in the event that the Mortgaged Property is sold or transferred without the prior written consent of the mortgagee thereunder;

(50)

The Mortgage Loan complies with all applicable consumer credit statutes and regulations, including, without limitation, the respective Uniform Consumer Credit Code laws in effect in Alabama, Colorado, Idaho, Indiana, Iowa, Kansas, Maine, Oklahoma, South Carolina, Utah, West Virginia and Wyoming, has been originated by a properly licensed entity, and in all other respects, complies with all of the material requirements of any such applicable laws;

(51)

The information set forth in the Prepayment Charge Schedule is complete, true and correct in all material respects and, subject to applicable federal and state law, each Prepayment Charge is permissible, enforceable and collectable;

(52)

The Mortgage Loan was not prepaid in full prior to the Closing Date and the Originator has not received notification from a Mortgagor that a prepayment in full shall be made after the Closing Date;

(53)

No Mortgage Loan is secured by cooperative housing, commercial property or mixed use property;

(54)

Each Mortgage Loan is eligible for sale in the secondary market or for inclusion in a Pass-Through Transfer without unreasonable credit enhancement;

(55)

Except as set forth on the related Mortgage Loan Schedule, none of the Mortgage Loans are subject to a prepayment penalty. For any Mortgage Loan originated prior to October 1, 2002 that is subject to a Prepayment Charge, such Prepayment Charge does not extend beyond five years after the date of origination. For any Mortgage Loan originated on or following October 1, 2002 that is subject to a prepayment penalty, such prepayment penalty does not extend beyond three years after the date of origination. With respect to any Mortgage Loan that contains a provision permitting imposition of a premium upon a prepayment prior to maturity: (i) prior to the Mortgage Loan’s origination, the Mortgagor agreed to such premium in exchange for a monetary benefit, including but not limited to a rate or fee reduction, (ii) prior to the Mortgage Loan’s origination, the Mortgagor was offered the option of obtaining a Mortgage Loan that did not require payment of such a premium, (iii) the prepayment premium is disclosed to the Mortgagor in the loan documents pursuant to applicable state and federal law, and (iv) notwithstanding any state or federal law to the contrary, the Originator shall not impose such prepayment premium in any instance when the mortgage debt is accelerated as the result of the Mortgagor’s default in making the loan payments;

(56)

The Originator has complied with all applicable anti-money laundering laws and regulations, including without limitation the USA Patriot Act of 2001 (collectively, the “Anti-Money Laundering Laws”); the Originator has established an anti-money laundering compliance program as required by the Anti-Money Laundering Laws, has conducted the requisite due diligence in connection with the origination of each Mortgage Loan for purposes of the Anti-Money Laundering Laws, including with respect to the legitimacy of the applicable Mortgagor and the origin of the assets used by the said Mortgagor to purchase the property in question, and maintains, and will maintain, sufficient information to identify the applicable Mortgagor for purposes of the Anti-Money Laundering Laws. No Mortgage Loan is subject to nullification pursuant to Executive Order 13224 (the “Executive Order”) or the regulations promulgated by the Office of Foreign Assets Control of the United States Department of the Treasury (the “OFAC Regulations”) or in violation of the Executive Order or the OFAC Regulations, and no Mortgagor is subject to the provisions of such Executive Order or the OFAC Regulations nor listed as a “blocked person” for purposes of the OFAC Regulations;

(57)

No Mortgagor was encouraged or required to select a Mortgage Loan product offered by the Originator which is a higher cost product designed for less creditworthy borrowers, unless at the time of the Mortgage Loan’s origination, such Mortgagor did not qualify taking into account credit history and debt to income ratios for a lower cost credit product then offered by the Originator or any affiliate of the Originator. If, at the time of loan application, the Mortgagor may have qualified for a lower cost credit product then offered by any mortgage lending affiliate of the Originator, the Originator referred the Mortgagor’s application to such affiliate for underwriting consideration;

(58)

The methodology used in underwriting the extension of credit for each Mortgage Loan employs objective mathematical principles which relate the Mortgagor’s income, assets, liabilities and/or credit history to the proposed payment and such underwriting methodology does not rely on the extent of the Mortgagor’s equity in the collateral as the principal determining factor in approving such credit extension. Such underwriting methodology confirmed that at the time of origination (application/approval) the Mortgagor had a reasonable ability to make timely payments on the Mortgage Loan;

(59)

With respect to each Mortgage Loan, the Originator has fully and accurately furnished complete information on the related borrower credit files to Equifax, Experian and Trans Union Credit Information Company, in accordance with the Fair Credit Reporting Act and its implementing regulations, on a monthly basis and the Servicer for each Mortgage Loan will furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information on its borrower credit files to Equifax, Experian, and Trans Union Credit Information Company, on a monthly basis;

(60)

All points and fees related to each Mortgage Loan were disclosed in writing to the Mortgagor in accordance with applicable state and federal law and regulation. Except in the case of a Mortgage Loan in an original principal amount of less than $60,000 which would have resulted in an unprofitable origination, no Mortgagor was charged “points and fees” (whether or not financed) in an amount greater than 5.00% of the principal amount of such Mortgage Loan, such 5.00% limitation is calculated in accordance with Xxxxxx Mae’s anti-predatory lending requirements as set forth in the Xxxxxx Mae Guides. All fees and charges (including finance charges) and whether or not financed, assessed, collected or to be collected in connection with the origination and servicing of each Mortgage Loan were disclosed in writing to the related Mortgagor in accordance with applicable state and federal laws and regulations;

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account or Supplemental Interest Trust Account for payment hereunder and that neither the Trustee nor the Securities Administrator is 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 Trustee.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such day is not a Business Day, the Business Day immediately following (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. The Record Date applicable to each Distribution Date is the Business Day immediately preceding such Distribution Date.

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Securities Administrator in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder 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 offices designated by the Securities Administrator for such purposes or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee and the rights of the Certificateholders under the Agreement at any time by the parties to the Agreement with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement.

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 offices designated by the Securities Administrator for such purposes, accompanied by a written instrument of transfer in form satisfactory to the Securities Administrator 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 Fund 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 Trustee, the Depositor and the Securities Administrator and any agent of the Trustee, the Depositor or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Trustee, the Depositor, the Securities Administrator nor any such agent shall be affected by any notice to the contrary.

The Master Servicer, upon the instruction of the Depositor, shall purchase the Mortgage Loans and therefore cause the termination of the Trust on the initial Optional Termination Date, which is the Distribution Date following the month in which the aggregate Stated Principal Balance of the Mortgage Loans as of the last day of the related Due Period is less than or equal to 10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date; provided, however, the Master Servicer in its own right may exercise the option to purchase the Mortgage Loans and thereby cause the termination of the Trust on the Distribution Date following the month in which the aggregate Stated Principal Balance of the Mortgage Loans as of the last day of the related Due Period is less than or equal to 5% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date, if the Depositor has not previously provided instructions to the Master Servicer to exercise such option on the Depositor’s behalf on such Distribution Date.

The obligations and responsibilities created by the Agreement will terminate as provided in Section 11.01 of the Agreement.

Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

HSI Asset Securitization Corporation Trust 2006-OPT2

Mortgage Pass-Through Certificates, Series 2006-OPT2

STATE OF

)

) ss.:

COUNTY OF

)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of ___________________, the proposed Transferee of an Ownership Interest in a Class R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement (the “Agreement”), relating to the above-referenced Series, dated as of February 1, 2006 among HSI Asset Securitization Corporation, as depositor, Option One Mortgage Corporation, as servicer and originator, Xxxxx Fargo Bank, N.A., as master servicer, securities administrator and custodian, and Deutsche Bank National Trust Company, as trustee. Capitalized terms used, but not defined herein, 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, the Securities Administrator and the Trustee.

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.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are Non-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 a Non-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.

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 a Non-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.)

The Transferee has reviewed the provisions of Section 5.02(c) 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(c) 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.

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 a Non-Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Securities Administrator a certificate substantially in the form set forth as Exhibit H to the Agreement (a “Transferor Certificate”) to the effect that, among other things, such Transferee has no actual knowledge that the Person to which the Transfer is to be made is a Non-Permitted Transferee.

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. The Transferee has historically paid its debts as they have come due and intends to pay its debts as they come due in the future. The Transferee intends to pay all taxes due with respect to the Certificate as they become due.

The Transferee’s taxpayer identification number is __________.

The Transferee is not a Disqualified Non-U.S. Person as defined in the Agreement.

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 Residual 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 the applicable paragraph:

□

The present value of the anticipated tax liabilities associated with holding the Certificate, as applicable, does not exceed the sum of:

(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 that is subject to Title I of ERISA or a plan that is subject to Section 4975 of the Code or a plan subject to any Federal, state or local law that is substantially similar to Title I of ERISA or Section 4975 of the Code, and the Transferee is not acting on behalf of or investing plan assets of such a plan.
