This POOLING AND SERVICING AGREEMENT, dated as of December 1, 2006 (the “Agreement”), by and among X.X. XXXXXX ACCEPTANCE CORPORATION I, a Delaware corporation, as depositor (the “Depositor”), U.S. BANK NATIONAL ASSOCIATION, as trustee (the “Trustee”) and XXXXX FARGO BANK, N.A., in its dual capacities as master servicer (the “Master Servicer”) and securities administrator (the “Securities Administrator”) and acknowledged by X.X. XXXXXX MORTGAGE ACQUISITION CORP., a Delaware corporation, as seller (the “Seller”), for purposes of Sections 2.04 and 2.05 and JPMORGAN CHASE BANK, NATIONAL ASSOCIATION, a national banking association and THE BANK OF NEW YORK TRUST COMPANY, N.A., a national banking association, as custodians (each a “Custodian and together, the “Custodians”), for purposes of Sections 11.06, 11.07 and 11.09.

PRELIMINARY STATEMENT

The Depositor has acquired the Mortgage Loans from the Seller and at the Closing Date is the owner of the Mortgage Loans and the other property being conveyed by the Depositor to the Trustee hereunder for inclusion in the Trust Fund. On the Closing Date, the Depositor will acquire the Certificates from the Trustee as consideration for the Depositor’s transfer to the Trust Fund of the Mortgage Loans and the other property constituting the Trust Fund. The Depositor has duly authorized the execution and delivery of this Agreement to provide for the conveyance to the Trustee of the Mortgage Loans and the other property constituting the Trust Fund. All covenants and agreements made by the Depositor, the Master Servicer, the Securities Administrator and the Trustee herein, with respect to the Mortgage Loans and the other property constituting the Trust Fund, are for the benefit of the Holders from time to time of the Certificates. The Depositor, the Trustee, the Master Servicer and the Securities Administrator are entering into this Agreement, and the Trustee is accepting the Trust Fund created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

As provided herein, the Trustee shall elect that the Trust Fund (exclusive of the Yield Maintenance Agreement and the Reserve Fund) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each, a “REMIC”): Lower-Tier REMIC 1, Middle-Tier REMIC 1 and Upper-Tier REMIC 1. Each Certificate, other than the Residual Certificates, shall represent ownership of a regular interest in Upper-Tier REMIC 1 for purposes of the REMIC Provisions.

Lower-Tier REMIC 1 shall hold the assets of the Trust Fund (other than the Yield Maintenance Agreement and the Reserve Fund) and shall issue several uncertificated interests, including the LT-R-1 Interest, which is hereby designated as the sole residual interest in Lower-Tier REMIC 1. Each remaining uncertificated interest in Lower-Tier REMIC 1 is hereby designated as a REMIC regular interest.

Middle-Tier REMIC 1 shall hold the uncertificated REMIC regular interests issued by Lower-Tier REMIC 1 and shall issue several uncertificated interests, including the MT-R-1 Interest, which is hereby designated as the sole residual interest in Middle-Tier REMIC 1. Each remaining uncertificated interest in Middle-Tier REMIC 1 is hereby designated as a REMIC regular interest.

Upper-Tier REMIC 1 shall hold the uncertificated REMIC regular interests issued by Middle-Tier REMIC 1. Each of the Certificates (other than the Class A-R Certificate and the Exchangeable Certificates) and the Uncertificated REMIC Interests represent ownership of regular interests in Upper-Tier REMIC 1. Upper-Tier REMIC 1 shall also issue the Class A-R Certificate, which is hereby designated as the sole residual interest in Upper-Tier REMIC 1.

The latest possible maturity date of all REMIC regular interests created in this Agreement shall be the Latest Possible Maturity Date.

The Lower-Tier REMIC 1

The Lower Tier Interests in Lower-Tier REMIC 1 shall have the class designations, initial principal amounts, interest rates and corresponding Pool, Subgroup or Class of Certificates as set forth in the following table:

Class Designation	Initial Principal Amount	Certificate Interest Rate	Corresponding Pool, Subgroup or Class of Certificates
LT1-SG1-A (0.9% of SP Subgroup 1)	(1)	5.50%	1
LT1-SG1-B (0.1% of SP Subgroup 1)	(1)	5.50%	1
LT1-SG1-C (Excess of Subgroup 1)	(1)	5.50%	1
LT1-SG2-A (0.9% of SP Subgroup 2)	(1)	6.00%	2
LT1-SG2-B (0.1% of SP Subgroup 2)	(1)	6.00%	2
LT1-SG2-C (Excess of Subgroup 2)	(1)	6.00%	2
LT1-SG3-A (0.9% of SP Subgroup 3)	(1)	7.00%	3
LT1-SG3-B (0.1% of SP Subgroup 3)	(1)	7.00%	3

_______________

(1)

Each Class A Interest will have a principal balance initially equal to 0.9% of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable in each case, the (“SP”), of its corresponding Pool or Subgroup, as applicable. Each Class B Interest will have a principal balance initially equal to 0.1% of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable, of its corresponding Pool or Subgroup, as applicable. The initial principal balance of each Class C Interest will equal the excess of the initial aggregate principal balance of its corresponding Pool or Subgroup, as applicable (less the initial principal balance of any principal-only interest in the Lower-Tier REMIC 1 payable from such Pool or Subgroup) over the initial aggregate principal balances of the Class A and Class B Interests corresponding to such Pool or Subgroup, as applicable.

(2)

This interest shall be an interest-only regular interest and shall bear interest on its notional principal amount, which shall be equal at all times to the Class Notional Amount of the Class A-X Certificates.

(3)

This Lower Tier Interest shall have an initial principal balance equal to the initial principal balance of its Corresponding Class of Certificates.

(4)

This Lower Tier Interest shall bear interest at the same rate as the Certificate Interest Rate of its Corresponding Class of Certificates.

(5)

The Class LT-R-1 Interest is the sole class of residual interest in the Lower-Tier REMIC 1. It has no principal balance and pays no principal or interest.

On each Distribution Date, the Available Distribution Amount shall be distributed with respect to the Lower Tier Interests in the following manner:

(1)

Interest shall be distributed with respect to each Lower-Tier Interest at the rate, or according to the formulas, described above;

(2)

Principal if no Cross-Over Situation Exists. If no Cross-Over Situation exists with respect to any Class of Interests, then Principal Amounts arising with respect to each Pool or Subgroup, as applicable, will be allocated: first to cause the Pool's or Subgroup’s, as applicable, corresponding Class A and Class B to equal, respectively, 0.9% of the related SP and 0.1% of the SP; and second to the Pool's or Subgroup’s, as applicable, corresponding Class C Interest;

(3)

Principal if a Cross-Over Situation Exists. If a Cross-Over Situation exists with respect to the Class A and Class B Interests then:

(a)

if the Calculation Rate in respect of the outstanding Class A and Class B Interests relating to a Group of Subordinate Certificates would be less than the Certificate Interest Rate of such Group of Subordinate Certificates, Principal Relocation Payments will be made proportionately to the outstanding Class A Interests prior to any other Principal Distributions from each such Pool or Subgroup, as applicable; and

(b)

if the Calculation Rate in respect of the outstanding Class A and Class B Interests would be greater than the Certificate Interest Rate of such Group of Subordinate Certificates, Principal Relocation Payments will be made proportionately to the outstanding Class B Interests prior to any other Principal Distributions from each such Pool or Subgroup, as applicable.

In each case, Principal Relocation Payments will be made so as to cause the Calculation Rate in respect of the outstanding Class A and Class B Interests relating to a Group of Subordinate Certificates to equal the Certificate Interest Rate of such Group or Subordinate Certificates. With respect to each Pool or Subgroup, as applicable, if (and to the extent that) the sum of (a) the principal payments comprising the Principal Remittance Amount received during the Due Period and (b) the Realized Losses, are insufficient to make the necessary reductions of principal on the Class A and Class B Interests, then interest will be added to the Pool's or Subgroup’s, as applicable, other Interests that are not receiving Principal Relocation Payments, in proportion to their principal balances.

(c)

The outstanding aggregate Class A and Class B Interests for all Pools and Subgroups will not be reduced below 1 percent of the excess of (i) the aggregate outstanding Class Principal Amounts of all Pools and Subgroups as of the end of any Due Period over (ii) the Senior Certificates for all Pools and Subgroups as of the related Distribution Date (after taking into account distributions of principal on such Distribution Date).

(d)

If (and to the extent that) the limitation in paragraph (c) prevents the distribution of principal to the Class A and Class B Interests of a Pool or Subgroup, as applicable, and if the Pool's or Subgroup’s, as applicable, Class C Interest has already been reduced to zero, then the excess principal from that Pool or Subgroup, as applicable, will be paid to the Class C Interests of the other Pool or Subgroup, as applicable, the aggregate Class A and Class B Interests of which are less than one percent of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable. If the Pool or Subgroup, as applicable, of the Class C Interest that receives such payment has a weighted average Net Mortgage Rate below the weighted average Net Mortgage Rate of the Pool making the payment, then the payment will be treated by the Lower-Tier REMIC 1 as a Realized Loss. Conversely, if the Pool or Subgroup, as applicable, of the Class C Interest that receives such payment has a weighted average Net Mortgage Rate above the weighted average Net Mortgage Rate of the Pool or Subgroup, as applicable, making the payment, then the payment will be treated by the Lower-Tier REMIC 1 as a reimbursement for prior Realized Losses.

On each Distribution Date, Prepayment Penalties with respect to the Mortgage Loans shall be distributed to the Class LT1-P Interest, which shall be entitled to receive its principal balance on the same Distribution Date that principal is payable to the Class P Certificates.

MIDDLE-TIER REMIC 1

The Lower-Tier Interests in Middle-Tier REMIC 1 shall have the class designations, initial principal amounts, interest rates and corresponding Pool, Subgroup or Class of Certificates as set forth in the following table:

(1) This Lower-Tier Interest shall have an interest rate equal to that of its Corresponding Class of Certificates.

(2) This Lower-Tier Interest shall have an initial principal amount equal to that of its Corresponding Class of Certificates (or, in the case of the Class MT1-A-1 and Class MT1-A-8 Interests, the Class A-1 and Class A-8 Certificates, respectively.)

(3) The Class MT-R-1 Interest is the sole class of residual interest in the Middle-Tier REMIC 1. It has no principal balance and pays no principal or interest.

(4) This Lower-Tier Interest shall not have a principal balance but shall bear interest on its notional principal balance which shall be equal at all times to the Class A-X Notional Amount.

On each Distribution Date, the Available Distribution Amount with respect to Aggregate Pool I shall be distributed with respect to the Lower Tier Interests in Middle-Tier REMIC 1 in the following manner:

(1)

Interest shall be distributed with respect to each Lower-Tier Interest at the rate, or according to the formulas, described above;

(2)

Principal and Realized Losses shall be allocated to each Lower-Tier Interest in an amount equal to that allocable to each Corresponding Class of Certificates for such Lower-Tier Interest on such Distribution Date.

On each Distribution Date, the Class MT1-P Interest shall be entitled to receive all amounts distributed with respect to the Class LT1-P Interest.

(1)

On each Distribution Date, the Certificate Interest Rate on the Class A-1 Certificates will be equal to LIBOR plus the related Certificate Margin, subject to a minimum Certificate Interest Rate of 0.550% per annum and a maximum Certificate Interest Rate of 9.500% per annum. Any interest payable on the Class A-1 Certificates in excess of the interest payable to such Classes at a Certificate Interest Rate of 6.000% per annum will be payable solely from amounts received in respect of the Yield Maintenance Agreement. After the Distribution Date in March 2011, the maximum Certificate Interest Rate applicable to the Class A-1 Certificates is 6.00% per annum.

(2)

The Certificate Interest Rate on the Class A-2 Certificates will be equal to the excess of (a) 5.450% over (b) LIBOR, but not less than 0.000% per annum.

(3)

Interest will accrue on the Class A-2 Notional Amount.

(4)

On each Distribution Date, the Certificate Interest Rate on the Class A-8 Certificates will be equal to LIBOR plus the related Certificate Margin, subject to a minimum Certificate Interest Rate of 0.380% per annum and a maximum Certificate Interest Rate of 7.000% per annum.

(5)

The Certificate Interest Rate on the Class A-9 Certificates will be equal to the excess of (a) 6.620% over (b) LIBOR, but not less than 0.000% per annum.

(6)

Interest will accrue on the Class A-9 Notional Amount.

(7)

The Class A-P Certificates will not receive any distributions of interest.

(8)

The Certificate Interest Rate applicable to each of the Class M, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates will equal a per annum rate calculated as the quotient expressed as a percentage of (a) the sum of (i) the product of (x) 5.500% and (y) the Subgroup Subordinate Amount relating to Subgroup 1 for that Distribution Date, (ii) the product of (x) 6.000% and (y) the Subgroup Subordinate Amount relating to Subgroup 2 for that Distribution Date and (iii) the product of (x) 7.000% and (y) the Subgroup Subordinate Amount relating to Subgroup 3 for that Distribution Date, divided by (b) the aggregate of the Subgroup Subordinate Amounts relating to each Subgroup for that Distribution Date.

(9)

The Class P Certificates will be entitled to all prepayment penalties on the Mortgage Loans.

(10)

These classes shall be issued in uncertificated form and shall constitute theUncertificated REMIC Interests. Each Class of Exchangeable REMIC Certificates issued under the Trust Agreement will be entitled to the same distributions of principal and interest as the corresponding Uncertificated REMIC Interest.

(11)

The Class A-13 Certificates are Exchangeable Certificates which will not be issued under this Pooling and Servicing Agreement.

(12)

The Class A-X Certificates will not receive any distributions of principal. Interest will accrue on the Class A-X Notional Amount, which is initially equal to $2,169,341.22.

As of the Cut-off Date, the Mortgage Loans had an Aggregate Stated Principal Balance of $778,192,218.26.

The foregoing REMIC structure is intended to cause all of the cash from the Mortgage Loans to flow through to Upper-Tier REMIC 1 as cash flow on a REMIC regular interest, without creating any shortfall—actual or potential (other than for credit losses) to any REMIC regular interest. To the extent that the structure is believed to diverge from such intention the parties identifying such ambiguity shall notify the other parties hereto and the parties involved will resolve such ambiguities to accomplish such result and will to the extent necessary rectify any drafting errors or seek clarification to the structure without Certificateholder approval (but with guidance of Counsel) to accomplish such intention, making any amendments in accordance with Section 12.03 of this Agreement.

To the extent that any costs and damages are incurred by the Trust Fund as a result of any violation of any applicable federal, state, or local predatory or abusive lending law arising from or in connection with the origination of any Mortgage Loan repurchased by the related Originator or the Seller, such costs and damages shall be included in the Purchase Price of such repurchased Mortgage Loan and shall be borne by the Seller. The Purchase Price for the repurchased Mortgage Loan shall be deposited in the related Distribution Account, and the Trustee, or its designee, upon receipt of written certification from the Securities Administrator of such deposit, shall release or cause the applicable Custodian to release to the related Originator or the Seller, as applicable, the related Trustee Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranties, as either party shall furnish to it and as shall be necessary to vest in such party any Mortgage Loan released pursuant hereto and the Trustee, or its designee, shall have no further responsibility with regard to such Trustee Mortgage File (it being understood that the Trustee shall have no responsibility for determining the sufficiency of such assignment for its intended purpose). If pursuant to the foregoing provisions the related Originator or the Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the related Servicer shall cause MERS to designate on the MERS® System the related Originator or the Seller, as applicable, as the beneficial holder of such Mortgage Loan.

In lieu of repurchasing any such Mortgage Loan as provided above, either party may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Replacement Mortgage Loans in the manner and subject to the limitations set forth in Section 2.05(b) below. It is understood and agreed that the obligations of the Originators and the Seller to cure or to repurchase (or to substitute for) any related Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy against the such party respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders.

Monthly Payments due with respect to Replacement Mortgage Loans in the month of substitution shall not be included as part of the Trust Fund and shall be retained by the related Originator or the Seller, as applicable. For the month of substitution, distributions to the Certificateholders shall reflect the collections and recoveries in respect of such Deleted Mortgage in the Due Period preceding the month of substitution and the related Originator or the Seller, as applicable, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. Upon such substitution, such Replacement Mortgage Loan shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this Agreement and the related Purchase and Servicing Agreement or Purchase Agreement, as applicable, as modified by the related Acknowledgement, including all representations and warranties thereof included in such Purchase and Servicing Agreement or Purchase Agreement, as applicable, as modified by the Acknowledgement, in each case as of the date of substitution.

For any month in which an Originator or the Seller substitutes one or more Replacement Mortgage Loans for one or more Deleted Mortgage Loans, the related Servicer shall determine the excess (each, a “Substitution Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate Stated Principal Balance of the Replacement Mortgage Loans replacing such Deleted Mortgage Loans, together with one month’s interest on such excess amount at the applicable Net Mortgage Rate. On the date of such substitution, the related Originator or Seller, as applicable, shall deliver or cause to be delivered to the related Servicer for deposit in the related Custodial Account an amount equal to the related Substitution Amount, if any, and the applicable Custodian, on behalf of the Trustee, upon receipt of the related Replacement Mortgage Loan or Loans and certification by such Servicer of such deposit, shall release to the related Originator or the Seller, as applicable, the related Trustee Mortgage File or Files and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty as the related Originator or Seller shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the related Originator or the Seller, as applicable, shall obtain at its own expense and deliver to the Trustee and the Securities Administrator an Opinion of Counsel to the effect that such substitution (either specifically or as a class of transactions) shall not cause an Adverse REMIC Event. If such Opinion of Counsel can not be delivered, then such substitution may only be effected at such time as the required Opinion of Counsel can be given.

(c)

Upon discovery by the related Originator, the Seller, the Depositor or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two (2) Business Days give written notice thereof to the other parties. In connection therewith, the applicable party shall repurchase or, subject to the limitations set forth in Section 2.05(b), substitute one or more Replacement Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.05(a) above. The Trustee shall re-convey to the related Originator or the Seller, as applicable, the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

SECTION 2.06

Grant Clause.

(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 in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and all proceeds of any and all property constituting the Trust Fund to secure payment of the Certificates; and (3) this Agreement shall constitute a security agreement under applicable law. 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 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 will be maintained as such throughout the term of this Agreement. The Depositor will, 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 an Originator, the Depositor or the Trustee, (2) any change of location of the place of business or the chief executive office of the Seller or the Depositor, (3) any transfer of any interest of an Originator or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws. Neither the Originators 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, any Originator 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 mediate transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, each of the Originators and the Depositor authorizes its immediate or mediate 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), it being understood that such immediate or mediate transferees are under no obligation to make such filings.

ARTICLE III

THE CERTIFICATES

SECTION 3.01

The Certificates.

(a)

The Certificates, other than the Uncertificated REMIC Interests, shall be issuable in registered form only and shall be securities governed by Article 8 of the New York Uniform Commercial Code. The Uncertificated REMIC Interests and the Uncertificated Interests shall be issuable as uncertificated securities in registered form only and shall be securities governed by Article 8 of the New York Uniform Commercial Code. The Book-Entry Certificates will be evidenced by one or more certificates, beneficial ownership of which will be held in the dollar denominations in Certificate Principal Amount, or Notional Amount, as applicable, or in the Percentage Interests, specified herein. Each Class of Book-Entry Certificates and Uncertificated REMIC Interests will be issued in the minimum denominations in Certificate Principal Amount (or Notional Amount) specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof. Each Class of Definitive Certificates, other than the Residual Certificates, shall be issued in definitive, fully registered form in the minimum denominations in Certificate Principal Amount specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof (except for one Class B-6 Certificate which may be issued in integral multiples of $0.01). The Class A-R and Class P Certificates shall be issued as single Certificates and maintained in definitive, fully registered form in a denomination equal to 100% of the Percentage Interest of each such Class. Each Uncertificated Interest shall be maintained in fully registered form.

(b)

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer of the Trustee or of the Securities Administrator on its behalf. Each Certificate shall, on original issue, be authenticated by the Authenticating Agent upon the written order of the Depositor upon receipt by the Trustee or the applicable Custodian on behalf of the Trustee of the Trustee Mortgage Files described in Section 2.01. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein, executed by an authorized officer of the Authenticating Agent, by manual signature, and such certification upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. At any time and from time to time after the execution and delivery of this Agreement, the Depositor may deliver Certificates executed by the Trustee or the Securities Administrator on behalf of the Trustee to the Authenticating Agent for authentication and the Authenticating Agent shall authenticate and deliver such Certificates as in this Agreement provided and not otherwise.

SECTION 3.02

Registration.

The Securities Administrator is hereby appointed, and the Securities Administrator hereby accepts its appointment as, initial Certificate Registrar in respect of the Certificates and shall maintain books for the registration and for the transfer of Certificates and the Uncertificated Interests (the “Certificate Register”). The Trustee may appoint a bank or trust company to act as successor Certificate Registrar. A registration book shall be maintained for the Certificates and the Uncertificated Interests collectively. The Certificate Registrar may resign or be discharged or removed and a new successor may be appointed in accordance with the procedures and requirements set forth in Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or removal of the Securities Administrator and the appointment of a successor Securities Administrator. The Certificate Registrar may appoint, by a written instrument delivered to the Holders and the Master Servicer, any bank or trust company to act as co-registrar under such conditions as the Certificate Registrar may prescribe; provided, however, that the Certificate Registrar shall not be relieved of any of its duties or responsibilities hereunder by reason of such appointment. The Certificate Register in respect of the Uncertificated Interests shall contain a statement that transfers of an Uncertificated Interest to a Disqualified Organization are prohibited as provided in this Agreement.

SECTION 3.03

Transfer and Exchange of Certificates.

(a)

A Definitive Certificate (other than Book-Entry Certificates which shall be subject to Section 3.09 hereof) may be transferred by the Holder thereof only upon presentation and surrender of such Certificate at the office of the Certificate Registrar duly endorsed or accompanied by an assignment duly executed by such Holder or his duly authorized attorney in such form as shall be satisfactory to the Certificate Registrar. Upon the transfer of any Definitive Certificate in accordance with the preceding sentence, the Trustee or the Securities Administrator on behalf of the Trustee shall execute, and the Authenticating Agent shall authenticate and deliver to the transferee, one or more new Certificates of the same Class and evidencing, in the aggregate, the same aggregate Certificate Principal Amount (or Notional Amount) as the Certificate being transferred. An Uncertificated Interest or Uncertificated REMIC Interest may be transferred by the Holder thereof upon written notice to the Certificate Registrar, satisfaction of the other conditions set forth in this Section 3.03 and, with respect to the Uncertificated REMIC Interests, the consent of the Depositor. No service charge shall be made to a Certificateholder for any registration of transfer of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any registration of transfer of Certificates.

(b)

A Definitive Certificate (other than Book-Entry Certificates which shall be subject to Section 3.09 hereof) may be exchanged by the Holder thereof for any number of new Certificates of the same Class, in authorized denominations, representing in the aggregate the same Certificate Principal Amount (or Notional Amount) as the Certificate surrendered, upon surrender of the Certificate to be exchanged at the office of the Certificate Registrar duly endorsed or accompanied by a written instrument of transfer duly executed by such Holder or his duly authorized attorney in such form as is satisfactory to the Certificate Registrar. Definitive Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered. No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates. Whenever any Definitive Certificates are so surrendered for exchange, the Trustee, or the Securities Administrator on behalf of the Trustee, shall execute, and the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)

By acceptance of a Restricted Certificate, whether upon original issuance or subsequent transfer, each Holder of such a Certificate acknowledges the restrictions on the transfer of such Certificate set forth thereon and agrees that it will transfer such a Certificate only as provided herein.

The following restrictions shall apply with respect to the transfer and registration of transfer of a Restricted Certificate:

(i)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is (x) to the Depositor or an affiliate (as defined in Rule 405 under the Act) of the Depositor or (y) being made to a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Act by a transferor that has provided the Certificate Registrar with a certificate in the form of Exhibit H hereto; and

(ii)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is being made to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Act, or to any Person all of the equity owners in which are such accredited investors, by a transferor who furnishes to the Certificate Registrar a letter of the transferee substantially in the form of Exhibit I hereto.

(d)

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate or that is an Uncertificated Interest shall be made to any Person or shall be effective unless the Certificate Registrar, on behalf of the Trustee, has received (A) a certificate substantially in the form of Exhibit J hereto (or Exhibit B, in the case of a Residual Certificate) from such transferee or (B) an Opinion of Counsel satisfactory to the Trustee and the Certificate Registrar to the effect that the purchase and holding of such a Certificate will not constitute or result in any nonexempt prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, any Servicer, the Depositor or the Securities Administrator to any obligation in addition to those undertaken in the Agreement; provided, however, that the Certificate Registrar will not require such certificate or opinion in the event that, as a result of a change of law or otherwise, counsel satisfactory to the Certificate Registrar has rendered an opinion to the effect that the purchase and holding of an ERISA-Restricted Certificate by an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA, or Section 4975 of the Code, (collectively, a “Plan”) or a Person that is purchasing or holding such a Certificate with the assets of a Plan will not constitute or result in a prohibited transaction under Title I of ERISA or Section 4975 of the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, the Depositor, the Securities Administrator or any Servicer to any obligation in addition to those undertaken in this Agreement. Each Transferee of an ERISA-Restricted Certificate that is a Book-Entry Certificate shall be deemed to have made the representations set forth in Exhibit J. The preparation and delivery of the certificate and opinions referred to above shall not be an expense of the Trust Fund, the Certificate Registrar, the Trustee, the Master Servicer, any Servicer the Depositor or the Securities Administrator.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial transfer of the ERISA-Restricted Certificates. The Certificate Registrar shall have no obligation to monitor transfers of Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no liability for transfers of such Certificates in violation of the transfer restrictions. The Certificate Registrar shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 3.03(d) and none of the Securities Administrator, the Trustee or the Paying Agent shall have any liability 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 by the Certificate Registrar in accordance with the foregoing requirements. The Securities Administrator, on behalf of the Trustee, shall be entitled, but not obligated, to recover from any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person acting on behalf of a Plan any payments made on such ERISA-Restricted Certificate at and after either such time. Any such payments so recovered by the Securities Administrator, on behalf of the Trustee, shall be paid and delivered by the Securities Administrator, on behalf of the Trustee, to the last preceding Holder of such Certificate that is not such a Plan or Person acting on behalf of a Plan.

(e)

As a condition of the registration of transfer or exchange of any Certificate, the Certificate Registrar may require the certified taxpayer identification number of the owner of the Certificate and the payment of a sum sufficient to cover any tax or other governmental charge imposed in connection therewith; provided, however, that the Certificate Registrar shall have no obligation to require such payment or to determine whether or not any such tax or charge may be applicable. No service charge shall be made to the Certificateholder for any registration, transfer or exchange of a Certificate.

(f)

Notwithstanding anything to the contrary contained herein, no Residual Certificate may be owned, pledged or transferred, directly or indirectly, by or to (i) a Disqualified Organization or (ii) an individual, corporation or partnership or other person unless such person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Certificate Registrar with an effective Internal Revenue Service Form W 8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a “Non-permitted Foreign Holder”).

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate, the proposed transferee shall deliver to the Trustee and the Certificate Registrar an affidavit in substantially the form attached hereto as Exhibit B representing and warranting, among other things, that such transferee is neither a Disqualified Organization, an agent or nominee acting on behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder (any such transferee, a “Permitted Transferee”), and the proposed transferor shall deliver to the Trustee and the Certificate Registrar an affidavit in substantially the form attached hereto as Exhibit C. In addition, the Trustee or the Certificate Registrar may (but shall have no obligation to) require, prior to and as a condition of any such transfer, the delivery by the proposed transferee of an Opinion of Counsel, addressed to the Trustee and the Certificate Registrar, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or a Non-permitted Foreign Holder. Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate. The Depositor, the Certificate Registrar and the Trustee shall be under no liability to any Person for any registration or transfer of a Residual Certificate to a Disqualified Organization, agent or nominee thereof or Non-permitted Foreign Holder or for the Paying Agent making any payments due on such Residual Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of the Agreement, so long as the transfer was effected in accordance with this Section 3.03(f), unless the Certificate Registrar shall have actual knowledge at the time of such transfer or the time of such payment or other action that the transferee is a Disqualified Organization, or an agent or nominee thereof, or Non-permitted Foreign Holder. The Certificate Registrar shall be entitled to recover from any Holder of a Residual Certificate that was a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the time it became a Holder or any subsequent time it became a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all payments made on such Residual Certificate at and after either such times (and all costs and expenses, including but not limited to attorneys’ fees, incurred in connection therewith). Any payment (not including any such costs and expenses) so recovered by the Certificate Registrar shall be paid and delivered to the last preceding Holder of such Residual Certificate.

If any purported transferee shall become a registered Holder of a Residual Certificate in violation of the provisions of this Section 3.03(f), then upon receipt of written notice to the Certificate Registrar that the registration of transfer of such Residual Certificate was not in fact permitted by this Section 3.03(f), the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of such registration of transfer of such Residual Certificate. The Depositor, the Certificate Registrar and the Trustee shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section 3.03(f), or for the Paying Agent making any payment due on such Certificate to the registered Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered upon receipt of the affidavit described in the preceding paragraph of this Section 3.03(f).

(g)

Each Holder or Certificate Owner of a Restricted Certificate, ERISA-Restricted Certificate or Residual Certificate, or an interest therein, by such Holder’s or Owner’s acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this section.

SECTION 3.04

Cancellation of Certificates.

Any Certificate surrendered for registration of transfer or exchange shall be cancelled and retained in accordance with normal retention policies with respect to cancelled certificates maintained by the Certificate Registrar.

SECTION 3.05

Replacement of Certificates.

If (i) any Certificate is mutilated and is surrendered to the Certificate Registrar or (ii) the Trustee or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and there is delivered to the Trustee and the Certificate Registrar such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Depositor, the Trustee or the Certificate Registrar that such destroyed, lost or stolen Certificate has been acquired by a protected purchaser the Trustee, or the Securities Administrator on behalf of the Trustee, shall execute and the Authenticating Agent shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Certificate Principal Amount. Upon the issuance of any new Certificate under this Section 3.05, the Trustee, the Depositor or the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee, the Depositor or the Certificate Registrar) connected therewith. Any replacement Certificate issued pursuant to this Section 3.05 shall constitute complete and indefeasible evidence of ownership in the applicable Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

If after the delivery of such new Certificate, a protected purchaser of the original Certificate in lieu of which such new Certificate was issued presents for payment such original Certificate, the Depositor, the Certificate Registrar and the Trustee or any agent shall be entitled to recover such new Certificate from the Person to whom it was delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expenses incurred by the Depositor, the Certificate Registrar, the Trustee or any agent in connection therewith.

SECTION 3.06

Persons Deemed Owners.

Subject to the provisions of Section 3.09 with respect to Book-Entry Certificates, the Depositor, the Master Servicer, the Trustee, the Certificate Registrar, the Paying Agent and any agent of any of them shall treat the Person in whose name any Certificate is registered upon the books of the Certificate Registrar as the owner of such Certificate for the purpose of receiving distributions pursuant to Sections 5.01 and 5.02 and for all other purposes whatsoever, and neither the Depositor, the Master Servicer, the Trustee, the Certificate Registrar, the Paying Agent nor any agent of any of them shall be affected by notice to the contrary.

SECTION 3.07

Temporary Certificates.

(a)

Pending the preparation of Definitive Certificates, upon the written order of the Depositor, the Trustee, or the Securities Administrator on behalf of the Trustee, shall execute and the Authenticating Agent shall authenticate and deliver temporary Certificates that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Certificates in lieu of which they are issued and with such variations as the authorized officers executing such Certificates may determine, as evidenced by their execution of such Certificates.

(b)

If temporary Certificates are issued, the Depositor will cause Definitive Certificates to be prepared without unreasonable delay. After the preparation of Definitive Certificates, the temporary Certificates shall be exchangeable for Definitive Certificates upon surrender of the temporary Certificates at the office or agency of the Certificate Registrar without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Securities Administrator, on behalf of the Trustee, shall execute and the Authenticating Agent shall authenticate and deliver in exchange therefor a like aggregate Certificate Principal Amount of Definitive Certificates of the same Class in the authorized denominations. Until so exchanged, the temporary Certificates shall in all respects be entitled to the same benefits under this Agreement as Definitive Certificates of the same Class.

SECTION 3.08

Appointment of Paying Agent.

The Trustee may appoint a Paying Agent (which may be the Trustee) for the purpose of making distributions to the Certificateholders hereunder. The Trustee hereby appoints the Securities Administrator as the initial Paying Agent. The Trustee shall cause any Paying Agent, other than the Securities Administrator, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee that such Paying Agent will hold all sums held by it for the payment to the Certificateholders in an Eligible Account (which shall be the Distribution Account) in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to the Certificateholders. All funds remitted by the Securities Administrator to any such Paying Agent for the purpose of making distributions shall be paid to the Certificateholders on each Distribution Date and any amounts not so paid shall be returned on such Distribution Date to the Securities Administrator. If the Paying Agent is not the Trustee or the Securities Administrator, the Trustee shall cause to be remitted to the Paying Agent on or before the Business Day prior to each Distribution Date, by wire transfer in immediately available funds, the funds to be distributed on such Distribution Date. Any Paying Agent shall be either a bank or trust company or otherwise authorized under law to exercise corporate trust powers.

SECTION 3.09

Book-Entry Certificates.

(a)

Each Class of Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates. The Book-Entry Certificates shall initially be registered on the Certificate Register in the name of the nominee of the Clearing Agency, and no Certificate Owner will receive a Definitive Certificate representing such Certificate Owner’s interest in the Book-Entry Certificates, except as provided in Section 3.09(c). Unless Definitive Certificates have been issued to Certificate Owners of Book-Entry Certificates pursuant to Section 3.09(c):

(i)

the provisions of this Section 3.09 shall be in full force and effect;

(ii)

the Certificate Registrar, the Paying Agent and the Trustee shall deal with the Clearing Agency for all purposes (including the making of distributions on the Book-Entry Certificates) as the authorized representatives of the Certificate Owners and the Clearing Agency and shall be responsible for crediting the amount of such distributions to the accounts of such Persons entitled thereto, in accordance with the Clearing Agency’s normal procedures;

(iii)

to the extent that the provisions of this Section 3.09 conflict with any other provisions of this Agreement, the provisions of this Section 3.09 shall control; and

(iv)

the rights of Certificate Owners shall be exercised only through the Clearing Agency and the Clearing Agency Participants and shall be limited to those established by law and agreements between such Certificate Owners and the Clearing Agency and/or the Clearing Agency Participants. Unless and until Definitive Certificates are issued pursuant to Section 3.09(c), the initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal of and interest on the Book-Entry Certificates to such Clearing Agency Participants.

(b)

Whenever notice or other communication to the Certificateholders is required under this Agreement, unless and until Definitive Certificates shall have been issued to Certificate Owners pursuant to Section 3.09(c), the Securities Administrator shall give all such notices and communications specified herein to be given to Holders of the Book-Entry Certificates to the Clearing Agency.

(c)

If (i) (A) the Clearing Agency or the Depositor advises the Paying Agent in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities with respect to the Book-Entry Certificates, and (B) the Depositor is unable to locate a qualified successor satisfactory to the Depositor and the Paying Agent, (ii) the Depositor, at its option, advises the Paying Agent in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) after the occurrence of an Event of Default, Certificate Owners representing beneficial interests aggregating not less than 50% of the Class Principal Amount of a Class of Book-Entry Certificates advise the Paying Agent and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Certificate Owners of a Class of Book-Entry Certificates, the Certificate Registrar shall notify the Clearing Agency to effect notification to all Certificate Owners, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates to Certificate Owners requesting the same. Upon surrender to the Certificate Registrar of the Book-Entry Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Certificate Registrar shall issue the Definitive Certificates. Neither the Depositor, the Certificate Registrar nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Clearing Agency shall be deemed to be imposed upon and performed by the Certificate Registrar, to the extent applicable, with respect to such Definitive Certificates and the Certificate Registrar shall recognize the holders of the Definitive Certificates as Certificateholders hereunder. Notwithstanding the foregoing, the Certificate Registrar, upon the written instruction of the Depositor, shall have the right to issue Definitive Certificates on the Closing Date in connection with credit enhancement programs.

On each Distribution Date, the Securities Administrator, as Paying Agent, shall distribute the aggregate of all Prepayment Premiums for the Mortgage Loans collected or paid by the Servicers and received by the Securities Administrator with respect to the preceding Prepayment Period to the Class P Certificates. Beginning with the first Distribution Date immediately following the expiration of the latest prepayment penalty term with respect to the Mortgage Loans and in no event later than the Distribution Date in December 2011, to the extent of available funds, on such date, the Class P Certificates shall be entitled to its outstanding Class Principal Amount from amounts on deposit in the Class P Reserve Fund.

SECTION 5.03

Allocation of Losses.

(a)

On each Distribution Date, the applicable Class PO Fraction of any Realized Loss, including any Excess Loss, on a Class PO Mortgage Component in Subgroup 1 will be allocated to the Class A-P Certificates until its Class Principal Amount is reduced to zero. To the extent funds are available on that Distribution Date or any future Distribution Date pursuant to Section 5.02(a)(ii), the related Class PO Shortfall Amount will be paid to the Class A-P Certificates, prior to distributions on Subordinate Certificates.

(b)

On or prior to each Distribution Date, the Securities Administrator shall aggregate the information provided by each Servicer with respect to the total amount of Realized Losses, including Excess Losses, experienced on the Mortgage Loans or Mortgage Components, as applicable, for the related Distribution Date.

Realized Losses on the Mortgage Loans with respect to any Distribution Date shall be allocated by the Securities Administrator to the Certificates as follows:

(1)

On each Distribution Date, the Realized Losses (other than Excess Losses) (other than the Class PO Fraction of Realized Losses on Class PO Mortgage Components) on the Mortgage Loans shall be allocated as follows:

second, to the Senior Certificates (other than the Interest-Only and Class A-P Certificates) of the Certificate Group related to the Mortgage Group sustaining such loss, pro rata, based on Class Principal Amounts, until the Class Principal Amount of each such Class of Senior Certificates is reduced to zero; provided however that Realized Losses that would otherwise be allocated to the Class A-1 and Class A-6 Certificates will instead be allocated to the Class A-4 Certificates, until the Class Principal Amount of the Class A-4 Certificates is reduced to zero.

(2)

On each Distribution Date, Excess Losses on a Mortgage Component in a Subgroup, other than the Class PO Fraction of the Excess Loss on a Class PO Mortgage Component, will be allocated pro rata among the Senior Certificates (other than the Interest-Only and Class A-P Certificates) of the related Certificate Group and the Mezzanine and Subordinate Certificates as follows: (i) in the case of such Senior Certificates, based on their Class Principal Amounts and (ii) in the case of the Mezzanine and Subordinate Certificates, pro rata based on each Classes’ share of the Apportioned Principal Balance for the related Mortgage Group; provided, however, on any Distribution Date on or after the Credit Support Deletion Date, any such Excess Losses will be allocated pro rata among the Senior Certificates (other than the Interest-Only and Class A-P Certificates) based on their respective Class Principal Amounts immediately prior to such Distribution Date.

(d)

On each Distribution Date, the Class Principal Amount of the Mezzanine and Subordinate Certificates then outstanding with the lowest payment priority shall be reduced by the Subordinate Certificate Writedown Amount.

(e)

Any allocation of a loss pursuant to this Section 5.03 to a Class of Certificates shall be achieved by reducing the Class Principal Amount thereof by the amount of such loss.

(f)

If Subsequent Recoveries have been received with respect to a Liquidated Mortgage Loan, the amount of such Subsequent Recoveries will be applied sequentially, in the order of payment priority, to increase the Class Principal Amount of each Class of Certificates to which Realized Losses have been allocated in respect of the related Liquidated Mortgage Loan, but in each case by not more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to this Section 5.03. Holders of such Certificates will not be entitled to any payment in respect of the Interest Distribution Amount on the amount of such increases for any Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied pro rata to the Principal Amount of each Certificate of such Class.

SECTION 5.04

Advances by Master Servicer.

If any Servicer fails to remit any Advance required to be made under the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, the Master Servicer shall itself make, or shall cause the successor Servicer to make, such Advance. If the Master Servicer determines that such an Advance is required, it shall on the Business Day immediately preceding the related Distribution Date remit to the Securities Administrator from its own funds (or funds advanced by such Servicer) for deposit in the Distribution Account immediately available funds in an amount equal to such Advance. The Master Servicer and each Servicer shall be entitled to be reimbursed for all Advances made by it. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is non-recoverable, the Master Servicer shall be under no obligation to make such Advance. If the Master Servicer determines that an Advance is non-recoverable, it shall, on or prior to the related Distribution Date, deliver an Officer’s Certificate to the Securities Administrator to such effect (provided, however, that the Master Servicer need not provide such Officer’s Certificate to the Securities Administrator so long as the Master Servicer and the Securities Administrator are the same Person).

SECTION 5.05

Compensating Interest Payments.

The amount of the aggregate Master Servicing Fees payable to the Master Servicer in respect of any Distribution Date shall be reduced (but not below zero) by the amount of any Compensating Interest Payment for such Distribution Date. Such amount shall not be treated as an Advance and shall not be reimbursable to the Master Servicer, unless a Servicer pays such Prepayment Interest Shortfall amount for a Distribution Date subsequent to that Distribution Date on which the Master Servicer paid such Compensating Interest Payment.

SECTION 5.06

Deposit of Uncertificated REMIC Interests.

The Uncertificated REMIC Interests shall be issued in uncertificated form to the Underwriter pursuant to the Underwriting Agreement and transferred by the Underwriter to the Exchange Trustee to be held in trust pursuant to terms of the Trust Agreement.

Any failure by the Master Servicer to comply with the provisions of Article XI.

If an Event of Default described in clauses (i) through (ix) of this Section shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Default shall not have been remedied within any period of time prescribed by this Section, the Trustee, by notice in writing to the Master Servicer may, and shall, if so directed by Certificateholders evidencing more than 50% of the Class Principal Amount of each Class of Certificates, terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer, and only in its capacity as Master Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee; and the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the defaulting Master 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. If Event of Default set forth in clause (x) occurs, the Depositor, at its sole option, but with the consent of the Trustee, may permit a cure period for the Master Servicer to deliver such Assessment of Compliance or Accountant’s Attestation, but in no event later than March 25^th of such year. The defaulting Master Servicer agrees to cooperate with the Trustee and the Securities Administrator in effecting the termination of the defaulting Master Servicer’s responsibilities and rights hereunder as Master Servicer including, without limitation, notifying the Servicers of the assignment of the master servicing function and providing the Trustee or its designee all documents and records in electronic or other form reasonably requested by it to enable the Trustee or its designee to assume the defaulting Master Servicer’s functions hereunder and the transfer to the Trustee for administration by it of all amounts which shall at the time be or should have been deposited by the defaulting Master Servicer in the Distribution Account and any other account or fund maintained with respect to the Certificates or thereafter received with respect to the Mortgage Loans. The Master Servicer being terminated shall bear all reasonable out-of-pocket costs of a master servicing transfer, including but not limited to those of the Trustee or Securities Administrator reasonably allocable to legal fees and expenses, accounting and financial consulting fees and expenses, and costs of amending the Agreement, if necessary.

Notwithstanding the termination of its activities as Master Servicer, each terminated Master Servicer shall continue to be entitled to reimbursement under this Agreement to the extent such reimbursement relates to the period prior to such Master Servicer’s termination.

If any Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge shall occur, the Trustee, upon becoming aware of the occurrence thereof, shall promptly notify the Securities Administrator and each Rating Agency of the nature and extent of such Event of Default. The Trustee or the Securities Administrator shall immediately give written notice to the Master Servicer upon the Master Servicer’s failure to make Advances as required under this Agreement.

(b)

On and after the time the Master Servicer receives a notice of termination from the Trustee pursuant to Section 6.14(a) or the Trustee receives the resignation of the Master Servicer evidenced by an Opinion of Counsel pursuant to Section 9.06, the Trustee, unless another master servicer shall have been appointed, shall be the successor in all respects to the Master Servicer in its capacity as such under this Agreement and the transactions set forth or provided for herein and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto and arising thereafter placed on the Master Servicer hereunder, including the obligation to make Advances with respect to the Mortgage Loans; provided, however, that any failure to perform such 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 addition, the Trustee shall have no responsibility for any act or omission of the Master Servicer prior to the receipt by the Master Servicer of any notice of termination. The Trustee shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.03. In the Trustee's capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. As compensation therefor, the Trustee shall be entitled to receive all compensation payable to the Master Servicer pursuant to Section 9.04 of this Agreement.

(c)

Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $15,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of a master servicer, like the Master Servicer. Any entity designated by the Trustee as a successor master servicer may be an Affiliate of the Trustee; provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer, the Trustee, in its individual capacity shall agree, at the time of such designation, to be and remain liable to the Trust Fund for such Affiliate’s actions and omissions in performing its duties hereunder. 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 no such compensation shall be in excess of that permitted to the Master Servicer hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession and may make other arrangements with respect to the servicing to be conducted hereunder which are not inconsistent herewith. The Master Servicer shall cooperate with the Trustee and any successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder including, without limitation, notifying Mortgagors of the assignment of the master servicing functions and providing the Trustee and successor master servicer, as applicable, all documents and records in electronic or other form reasonably requested by it to enable it to assume the Master Servicer’s functions hereunder and the transfer to the Trustee or such successor master servicer, as applicable, all amounts which shall at the time be or should have been deposited by the Master Servicer in the Distribution Account and any other account or fund maintained with respect to the Certificates or thereafter be received with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Master Servicer to deliver, or any delay in delivering, cash, documents or records to it, (ii) the failure of the Master Servicer to cooperate as required by this Agreement, (iii) the failure of the Master Servicer to deliver the Mortgage Loan data to the Trustee as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer. No successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Trustee to deliver, or any delay in delivering cash, documents or records to it related to such distribution, or (ii) the failure of Trustee to cooperate as required by this Agreement.

SECTION 6.15

Additional Remedies of Trustee Upon Event of Default.

During the continuance of any Event of Default, so long as such Event of Default shall not have been remedied, the Trustee, in addition to the rights specified in Section 6.14, shall have the right, in its own name and as trustee of the Trust Fund, to take all actions now or hereafter existing at law, in equity or by statute to enforce its rights and remedies and to protect the interests, and enforce the rights and remedies, of the Certificateholders (including the institution and prosecution of all judicial, administrative and other proceedings and the filings of proofs of claim and debt in connection therewith). Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy, and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default.

SECTION 6.16

Waiver of Defaults.

More than 50% of the Aggregate Voting Interests of the Certificateholders may waive any default or Event of Default by the Master Servicer in the performance of its obligations hereunder, except that a default in the making of any required deposit to the Distribution Account that would result in a failure of the Trustee or Securities Administrator to make any required payment of principal of or interest on the Certificates may only be waived with the consent of 100% of the affected Certificateholders. Upon any such waiver of a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. 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 6.17

Notification to Holders.

Upon termination of the Master Servicer or appointment of a successor to the Master Servicer, in each case as provided herein, the Trustee shall promptly mail notice thereof by first class mail to the Securities Administrator and the Certificateholders at their respective addresses appearing on the Certificate Register. The Trustee shall also, within 45 days after the occurrence of any Event of Default known to a Responsible Officer of the Trustee, give written notice thereof to the Securities Administrator and the Certificateholders, unless such Event of Default shall have been cured or waived prior to the issuance of such notice and within such 45-day period.

SECTION 6.18

SECTION 6.19

Action Upon Certain Failures of the Master Servicer and Upon Event of Default.

In the event that the Trustee or the Securities Administrator shall have actual knowledge of any action or inaction of the Master Servicer that would become an Event of Default upon the Master Servicer’s failure to remedy the same after notice, the Trustee or the Securities Administrator shall give notice thereof to the Master Servicer, provided that the Trustee shall be under no duty or obligation to independently ascertain whether any action or inaction of the Master Servicer has occurred.

SECTION 6.20

(a)

The Securities Administrator shall prepare or cause to be prepared and file on behalf of the Trust Fund, based upon information calculated in accordance with this Agreement pursuant to written instructions given by the Depositor, federal tax returns, all in accordance with Article X hereof.

The Master Servicer will indemnify the Securities Administrator and the Trustee for any liability of or assessment against the Securities Administrator or the Trustee, as applicable, resulting from any error in any of such tax or information returns directly resulting from errors in the information provided by the Master Servicer.

(b)

The Securities Administrator shall prepare and file with the Internal Revenue Service (“IRS”), on behalf of the Trust Fund and each REMIC created hereunder, an application for an employer identification number on IRS Form SS 4 or by any other acceptable method. The Securities Administrator shall also file a Form 8811 as required. The Securities Administrator, upon receipt from the IRS of the Notice of Taxpayer Identification Number Assigned, shall upon request promptly forward a copy of such notice to the Trustee and the Depositor.

(a)

The respective obligations and responsibilities of the Trustee, the Securities Administrator and the Master Servicer created hereby (other than the obligation of the Securities Administrator to make payments to the Certificateholders as set forth in Section 7.02), shall terminate on the earliest of (i) the final payment or other liquidation of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property, (ii) the later of the sale of the property held by the Trust Fund in accordance with Section 7.01(c) and (iii) the Latest Possible Maturity Date; provided, however, that in no event shall the Trust Fund created hereby continue beyond the expiration of 21 years from the death of the last 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. Any termination of the Trust Fund shall be carried out in such a manner so that the termination of each REMIC included therein shall qualify as a “qualified liquidation” under the REMIC Provisions.

(b)

[Reserved].

(c)

On any Distribution Date occurring on or after the Initial Optional Purchase Date, the Master Servicer has the option to purchase all of the Mortgage Loans and cause the Trust Fund to adopt a plan of complete liquidation pursuant to Sections 7.02 and 7.03 hereof and to sell all of its property. If the Master Servicer elects to exercise any such option, it shall no later than 30 days prior to the Distribution Date selected for purchase of the assets of the Trust Fund (the “Purchase Date”) deliver written notice to the Trustee and the Securities Administrator and either (a) deposit in the Distribution Account the related Redemption Price or (b) state in such notice that the related Redemption Price shall be deposited in the Distribution Account not later than 10:00 a.m., New York City time, on the applicable Purchase Date. Upon exercise of such option, the property of the Trust Fund shall be sold to the Master Servicer at a price equal to the related Redemption Price.

(d)

The Depositor, the Master Servicer, each Servicer, the Securities Administrator, the Trustee and each Custodian shall be reimbursed from the Redemption Price for any Advances, Servicer Advances, accrued and unpaid Servicing Fees and Master Servicing Fees or other amounts with respect to the Mortgage Loans that are reimbursable to such parties under this Agreement, the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, or the related Custodial Agreement.

In the event that any of the affected Holders do not surrender their Certificates for cancellation within three months after the time specified in the above-mentioned written notice, 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 one year after the second notice any applicable Certificates shall not have been surrendered for cancellation, the Securities Administrator may take appropriate steps to contact the remaining Certificateholders concerning surrender of such Certificates, and the cost thereof shall be paid out of the amounts distributable to such Holders. If within two years after the second notice any Certificates shall not have been surrendered for cancellation, the Securities Administrator shall deliver any remaining funds being held by it to the Depositor and the Depositor shall, subject to applicable state law relating to escheatment, hold all amounts distributable to such Holders for the benefit of such Holders. No interest shall accrue on any amount held by the Securities Administrator and not distributed to a Certificateholder due to such Certificateholder’s failure to surrender its Certificate(s) for payment of the final distribution thereon in accordance with this Section.

(c)

Any reasonable expenses incurred by the Trustee in connection with any redemption or termination or liquidation of the Trust Fund or a portion thereof shall be reimbursed from proceeds received from such liquidation of the Trust Fund.

SECTION 8.03

Acts of Holders of Certificates.

ARTICLE IX

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS
BY THE MASTER SERVICER

SECTION 9.01

Duties of the Master Servicer; Enforcement of Servicers; and Master Servicer’s Obligations.

(a)

The Master Servicer, on behalf of the Trustee, the Depositor and the Certificateholders shall monitor the performance of the Servicers under the Purchase and Servicing Agreements and the Servicing Agreements, and shall use its reasonable good faith efforts to cause the Servicers duly and punctually to perform all of their respective duties and obligations thereunder. Upon the occurrence of a default of which an Authorized Officer of the Master Servicer has actual knowledge under a Purchase and Servicing Agreement or Servicing Agreement, the Master Servicer shall promptly notify the Trustee thereof, and shall specify in such notice the action, if any, the Master Servicer is taking in respect of such default. So long as any such default shall be continuing, the Master Servicer may, and shall if it determines such action to be in the best interests of Certificateholders, (i) terminate all of the rights and powers of such Servicer pursuant to the applicable provisions of the related Purchase and Servicing Agreement or Servicing Agreement, as applicable; (ii) exercise any rights it may have to enforce the related Purchase and Servicing Agreement, or Servicing Agreement, as applicable, against such Servicer; and/or (iii) waive any such default under the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, or take any other action with respect to such default as is permitted thereunder. Notwithstanding any provision of this Agreement or any Purchase and Servicing Agreement or Servicing Agreement to the contrary, the Master Servicer shall have no duty or obligation to supervise, monitor or oversee the activities of, or to enforce the obligations of, a Servicer under its Purchase and Servicing Agreement or Servicing Agreement, as applicable, with respect to any Pledged Assets or any Limited Purpose Surety Bond relating thereto, including, without limitation, the collection of any amounts owing to the Trust Fund in respect thereof (unless and until the Master Servicer shall have assumed the obligations of such Servicer as successor servicer under the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, pursuant to this Section 9.01, in which case, as successor servicer, it shall be bound to serve and administer the Pledged Assets and any related Limited Purpose Surety Bond in accordance with the provisions of the related Purchase and Servicing Agreement or Servicing Agreement, as applicable).

The Master Servicer shall not permit a successor Servicer to perform any servicing responsibilities hereunder with respect to the Mortgage Loans unless that Servicer first agrees in writing to deliver an Assessment of Compliance and an Accountant’s Attestation in such manner and at such times that permits that Master Servicer to comply with the provisions hereof.

(b)

Upon any termination by the Master Servicer of a Servicer’s rights and powers pursuant to its Purchase and Servicing Agreement or Servicing Agreement, as applicable, the rights and powers of such Servicer with respect to the related Mortgage Loans shall vest in the Master Servicer and the Master Servicer shall be the successor in all respects to such Servicer in its capacity as Servicer with respect to such Mortgage Loans under the related Purchase and Servicing Agreement, or Servicing Agreement, as applicable, unless or until the Master Servicer shall have appointed, with the consent of the Trustee and the Rating Agencies, such consent not to be unreasonably withheld, and in accordance with the applicable provisions of the related Purchase and Servicing Agreement, or Servicing Agreement, as applicable, a new Xxxxxx Xxx- or FHLMC-approved Person to serve as successor to the Servicer; provided, however, that it is understood and agreed by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to a successor servicer (including the Master Servicer). With such consent, the Master Servicer may elect to continue to serve as successor servicer under the Purchase and Servicing Agreement or Servicing Agreement, as applicable. Upon appointment of a successor servicer, as authorized under this Section 9.01(b), unless the successor servicer shall have assumed the obligations of the terminated Servicer under such Purchase and Servicing Agreement or Servicing Agreement, as applicable, the Trustee and such successor servicer shall enter into a servicing agreement in a form substantially similar to the affected Purchase and Servicing Agreement or Servicing Agreement, as applicable. In connection with any such appointment, the Master Servicer may make such arrangements for the compensation of such successor servicer as it and such successor servicer shall agree, but in no event shall such compensation of any successor servicer (including the Master Servicer) be in excess of that payable to the Servicer under the affected Purchase and Servicing Agreement or Servicing Agreement, as applicable.

The Master Servicer shall pay the costs of such enforcement (including the termination of a Servicer, the appointment of a successor servicer or the transfer and assumption of the servicing by the Master Servicer at its own expense and shall be reimbursed therefor initially (i) by the terminated Servicer, (ii) from a general recovery resulting from such enforcement only to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans, (iii) from a specific recovery of costs, expenses or attorney’s fees against the party against whom such enforcement is directed, or (iv) to the extent that such amounts described in (i)-(iii) above are insufficient to reimburse the Master Servicer or the Trustee, as applicable, for such costs of enforcement, from the Trust Fund, as provided in Section 9.04.

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 any Servicer it replaces or for the errors or omissions of such Servicer.

(c)

Upon any termination of a Servicer’s rights and powers pursuant to its Purchase and Servicing Agreement or Servicing Agreement, as applicable, the Master Servicer or the Trustee, as applicable, shall promptly notify the Trustee and the Rating Agencies, specifying in such notice that the Master Servicer or any successor servicer, as the case may be, has succeeded such Servicer under the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, which notice shall also specify the name and address of any such successor servicer.

(d)

Neither the Depositor nor the Trustee shall consent to the assignment by any Servicer of such Servicer’s rights and obligations under the related Purchase and Servicing Agreement or Servicing Agreement, as applicable, without the prior written consent of the Master Servicer, which consent shall not be unreasonably withheld or delayed.

SECTION 9.02

Assumption of Master Servicing by Trustee.

(a)

In the event the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default under this Agreement), the Trustee shall thereupon assume all of the rights and obligations of such Master Servicer hereunder and under each Purchase and Servicing Agreement and Servicing Agreement entered into with respect to the Mortgage Loans or shall appoint a Xxxxxx-Xxx or FHLMC-approved servicer as successor servicer acceptable to the Depositor and the Rating Agencies. The Trustee, its designee or any successor master servicer appointed by the Trustee shall be deemed to have assumed all of the Master Servicer’s interest herein and therein to the same extent as if each Purchase and Servicing Agreement and Servicing Agreement had been assigned to the assuming party, except that the Master Servicer shall not thereby be relieved of any liability or obligations of the Master Servicer under each Purchase and Servicing Agreement and Servicing Agreement accruing prior to its replacement as Master Servicer, and shall be liable to the Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (but not its 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 thereunder.

(b)

The Master Servicer that has been terminated shall, upon request of the Trustee but at the expense of such Master Servicer, deliver to the assuming party all documents and records relating to each Purchase and Servicing Agreement and Servicing Agreement, this Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of each Purchase and Servicing Agreement, Servicing Agreement and this Agreement to the assuming party.

(ii)

the execution and delivery of this Agreement by the Master Servicer and its performance and compliance with the terms of this Agreement will not (A) violate the Master Servicer’s charter or bylaws, (B) violate any law or regulation or any administrative decree or order to which it is subject or (C) constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material contract, agreement or other instrument to which the Master Servicer is a party or by which it is bound or to which any of its assets are subject, which violation, default or breach would materially and adversely affect the Master Servicer’s ability to perform its obligations under this Agreement;

(iii)

this Agreement constitutes, assuming due authorization, execution and delivery hereof by the other respective parties hereto, a legal, valid and binding obligation of the Master Servicer, enforceable against it in accordance with the terms hereof, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights in general, and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law);

(iv)

the Master Servicer is not in default with respect to any order or decree of any court or any order or regulation of any federal, state, municipal or governmental agency to the extent that any such default would materially and adversely affect its performance hereunder;

(v)

the Master Servicer is not a party to or bound by any agreement or instrument or subject to any charter provision, bylaw or any other corporate restriction or any judgment, order, writ, injunction, decree, law or regulation that may materially and adversely affect its ability as Master Servicer to perform its obligations under this Agreement or that requires the consent of any third person to the execution of this Agreement or the performance by the Master Servicer of its obligations under this Agreement;

(vi)

no litigation is pending or, to the best of the Master Servicer’s knowledge, threatened against the Master Servicer which would prohibit its entering into this Agreement or performing its obligations under this Agreement;

(vii)

the Master Servicer, or an affiliate thereof the primary business of which is the servicing of conventional residential mortgage loans, is a Xxxxxx Mae- or FHLMC-approved seller/servicer;

(viii)

(ix)

the consummation of the transactions contemplated by this Agreement are in the ordinary course of business of the Master Servicer.

(b)

It is understood and agreed that the enforcement of the obligation of the Master Servicer set forth in this Section to indemnify the Depositor, the Securities Administrator and the Trustee as provided in this Section constitutes the sole remedy (other than as set forth in Section 6.14) of the Depositor, the Securities Administrator and the Trustee, respecting a breach of the foregoing representations and warranties. Such indemnification shall survive any termination of the Master Servicer as Master Servicer hereunder, and any termination of this Agreement.

Any cause of action against the Master Servicer relating to or arising out of the breach of any representations and warranties made in this Section shall accrue upon discovery of such breach by either the Depositor, the Master Servicer or the Trustee or notice thereof by any one of such parties to the other parties.

SECTION 9.04

Compensation to the Master Servicer.

As compensation for its services hereunder, the Master Servicer shall be entitled to be retain or withdraw the Master Servicing Fee from the Distribution Account, which shall be equal to (i) all investment income payable to the Master Servicer pursuant to Section 4.01(e) hereof (which amount shall be equal to 5 days investment income each month during the period from the Distribution Account Deposit Date to the related Distribution Date) and (ii) amounts necessary to reimburse itself for any previously unreimbursed Advances, Servicer Advances and Nonrecoverable Advances in accordance with the definition of “Available Distribution Amount.” The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement.

In addition, the Master Servicer shall be entitled to reimbursement from the Distribution Account for all reasonable expenses, disbursements and advances incurred or made by the Master Servicer in connection with the performance of its duties hereunder and under the Purchase and Servicing Agreements and Servicing Agreements, as modified by the Acknowledgements (including the reasonable compensation and the expenses and disbursements of its agents and counsel), to the extent not otherwise reimbursed pursuant to this Agreement, except any such expense, disbursement or advance as may be attributable to its willful misfeasance, bad faith or negligence.

SECTION 9.05

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 be a Person that shall be qualified and approved to service mortgage loans for Xxxxxx Mae or FHLMC and shall have a net worth of not less than $15,000,000.

SECTION 9.06

Resignation of Master Servicer.

Except as otherwise provided in Sections 9.05 and 9.07 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 shall have been appointed by the Trustee and until such successor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Written notice of such resignation shall be given promptly by the Master Servicer and the Depositor to the Trustee.

If, at any time, the Master Servicer resigns under this Section 9.06, or transfers or assigns its rights and obligations under Section 9.07, or is removed as Master Servicer pursuant to Section 6.14, then at such time Xxxxx Fargo Bank, N.A. also shall be entitled to resign as Securities Administrator, Paying Agent, Authenticating Agent and Certificate Registrar under this Agreement. In such event, the obligations of each such party shall be assumed by the Trustee or such successor master servicer appointed by the Trustee (subject to the provisions of Section 9.02(a)).

SECTION 9.07

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 hereunder; provided, however, that the Master Servicer shall have the right with the prior written consent of the Trustee and the Depositor (which consent shall not be unreasonably withheld), 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 downgrading 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 amount of the compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer. Such successor Master Servicer shall also pay the fees of the Trustee and the Securities Administrator, as provided herein.

SECTION 9.08

Limitation on Liability of the Master Servicer and Others.

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 misfeasance, bad faith or negligence in its 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 of any kind 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 to master service the Mortgage Loans in accordance with 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 expenses, costs and liabilities of the Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor out of the Distribution Account.

The Master Servicer shall not be liable for any acts or omissions of the Servicers 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 misfeasance, bad faith or recklessness of the Master Servicer in supervising, monitoring and overseeing the obligations of any servicer in this Agreement, the Purchase and Servicing Agreements and the Servicing Agreements.

SECTION 9.09

Indemnification; Third-Party Claims.

The Master Servicer agrees to indemnify the Depositor, the Securities Administrator and the Trustee, 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 or the Trustee may sustain as a result of the Master Servicer’s willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of its reckless disregard for its obligations and duties under this Agreement, the Purchase and Servicing Agreements and the servicing Agreements. The Depositor, 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 entitling the Depositor, the Securities Administrator or the Trustee to indemnification under this Section 9.09, 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; provided, however, that the failure to so notify the Master Servicer shall not affect the Depositor’s, the Securities Administrator’s or the Trustee’s right to indemnification hereunder except to the extent that the Master Servicer’s defense of any such claim has been materially prejudiced thereby.

ARTICLE X

REMIC ADMINISTRATION

SECTION 10.01

REMIC Administration.

(a)

REMIC elections as set forth in the Preliminary Statement shall be made on Forms 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement.

(b)

The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 860G(a)(9) of the Code. The latest possible maturity date for purposes of Treasury Regulation 1.860G-1(a)(4) will be the Latest Possible Maturity Date.

(c)

The Securities Administrator shall represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The Securities Administrator shall pay any and all tax-related expenses (not including taxes) of each REMIC, including but not limited to any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to such REMIC that involve the Internal Revenue Service or state tax authorities, but only to the extent that (i) such expenses are ordinary or routine expenses, including expenses of a routine audit but not expenses of litigation (except as described in (ii)); or (ii) such expenses or liabilities (including taxes and penalties) are attributable to the negligence or willful misconduct of the Securities Administrator in fulfilling its duties hereunder (including its duties as tax return preparer). The Securities Administrator shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Distribution Account, provided, however, the Securities Administrator shall not be entitled to reimbursement for expenses incurred in connection with the preparation of tax returns and other reports as required by Section 6.20 and this Section.

(d)

The Securities Administrator shall prepare, and the Trustee shall sign and file, as instructed by the Securities Administrator, all of each REMIC’s federal and appropriate state tax and information returns as such REMIC’s direct representative. The expenses of preparing and filing such returns shall be borne by the Securities Administrator. In preparing such returns, the Securities Administrator shall, with respect to each REMIC other than an Upper-Tier REMIC: (i) treat the accrual period for interests in such REMIC as the calendar month; (ii) account for distributions made from such REMIC as made on the first day of each succeeding calendar month; (iii) account for income under the all-OID method at the applicable Net WAC; (iv) use the aggregation method provided in Treasury Regulation section 1.1275-2(c); and (v) account for income and expenses related to such REMIC in the manner resulting in the lowest amount of excess inclusion income possible accruing to the Holder of the residual interest in such REMIC.

(e)

The Securities Administrator or its designee shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Securities Administrator shall provide, upon receipt of additional reasonable compensation, (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code and (ii) to the Certificateholders and the Trustee such information or reports as are required by the Code or REMIC Provisions.

(f)

To the extent within their control, the Trustee, the Securities Administrator, the Master Servicer and the Holders of Certificates shall take any action or cause any REMIC to take any action necessary to maintain the status of any REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, the Securities Administrator, the Master Servicer nor the Holder of any Residual Certificate or Uncertificated Interest shall knowingly take any action, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in an Adverse REMIC Event unless the Trustee, the Securities Administrator and the Master Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing any REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate or Uncertificated Interest will consult with the Trustee, the Securities Administrator, the Master Servicer or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee, the Securities Administrator or the Master Servicer has advised it in writing that an Adverse REMIC Event could occur; provided, however, that if no Adverse REMIC Event would occur but such action could result in the imposition of additional taxes on the Residual Certificateholders, no such Person shall take any such action, or cause any REMIC to take any such action without the written consent of the Residual Certificateholders.

(g)

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent that such taxes are not paid by a Residual Certificateholder, the Trustee or the Paying Agent shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in any such REMIC or, if no such amounts are available, out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to holders of regular interests in any such REMIC, as the case may be.

(h)

The Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to each REMIC on a calendar year and on an accrual basis.

(i)

No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement.

(j)

Neither the Securities Administrator nor the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)

The Securities Administrator shall treat the beneficial owners of the Certificates entitled to receive Basis Risk Shortfall Carryover Amounts as having entered into a notional principal contract. 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). For tax purposes, the notional principal contract shall be deemed to have a value in favor of the Certificates entitled to receive Basis Risk Shortfall Carryover Amounts, as of the Closing Date, of $15,000.

(l)

The Holder of a majority interest in the residual interest in any REMIC formed hereby shall act as “tax matters person” with respect to such REMIC and the Securities Administrator shall act as agent for such holder in such role, unless and until another party is so designated by such holder.

(m)

The Securities Administrator shall treat Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is owned by the Depositor and that is not an asset of any REMIC.

SECTION 10.02

Prohibited Transactions and Activities.

Neither the Depositor, the Master Servicer nor the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination of each REMIC pursuant to Article VII of this Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Distribution Account for gain, nor accept any contributions to any REMIC after the Closing Date, unless it has received an Opinion of Counsel (at the expense of the party causing such sale, disposition, substitution or acceptance) that such disposition, acquisition, substitution, or acceptance will not result in an Adverse REMIC Event, (b) affect the distribution of interest or principal on the Certificates or (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement).

SECTION 10.03

Indemnification with Respect to Prohibited Transactions or Loss of REMIC Status.

Upon the occurrence of an Adverse REMIC Event due to the negligent performance by the Securities Administrator of its duties and obligations set forth herein, the Securities Administrator shall indemnify the Certificateholders of the related Residual Certificate against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Securities Administrator shall not be liable for any such Losses attributable to the action or inaction of the Depositor, the Trustee or the Holder(s) of the Residual Certificates, nor for any such Losses resulting from misinformation provided by any of the foregoing parties on which the Securities Administrator has relied. Notwithstanding the foregoing, however, in no event shall the Securities Administrator have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement or under any Purchase and Servicing Agreements, Servicing Agreements or under any Acknowledgement, (2) for any Losses other than arising out of malfeasance, willful misconduct or negligent performance by the Securities Administrator of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders of the related Residual Certificate (in addition to payment of principal and interest on the Certificates).

SECTION 10.04

REO Property.

(a)

Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trustee hereunder, shall not, except to the extent provided in the applicable Purchase and Servicing Agreement or Servicing Agreement, as applicable, knowingly permit any Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might cause an Adverse REMIC Event unless the applicable Servicer has provided to the Trustee an Opinion of Counsel concluding that, under the REMIC Provisions, such action would not adversely affect the status of any REMIC as a REMIC and any income generated for any REMIC by the REO Property would not result in an Adverse REMIC Event.

(b)

The Depositor shall cause the applicable Servicer (to the extent provided in its Purchase and Servicing Agreement or Servicing Agreement, as applicable) to make reasonable efforts to sell any REO Property for its fair market value. In any event, however, the Depositor shall, or shall cause the applicable Servicer (to the extent provided in its Purchase and Servicing Agreement or Servicing Agreement, as applicable) to, dispose of any REO Property within three years of its acquisition by the Trust Fund unless the Depositor or the applicable Servicer (on behalf of the Trust Fund) has received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the REMIC may hold REO Property for a longer period without causing an Adverse REMIC Event. If such an extension has been received, then the Depositor, acting on behalf of the Trustee hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If such an extension has not been received and the Depositor or the applicable Servicer, acting on behalf of the Trust Fund hereunder, is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund or if such an extension, has been received and the Depositor or the applicable Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Depositor shall cause the applicable Servicer, before the end of the three year period or the Extended Period, as applicable, to (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the applicable Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be.

SECTION 10.05

Fidelity.

The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. 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 and trustees.

ARTICLE XI

EXCHANGE ACT REPORTING

SECTION 11.01

Form 10-D Reporting.

Within 15 days after each Distribution Date (subject to permitted extensions under the Exchange Act), the Securities Administrator shall prepare and file on behalf of the Trust Fund any Form 10-D required by the Exchange Act, in form and substance as required by the Exchange Act. The Securities Administrator shall file each Form 10-D with a copy of the related Monthly Statement attached thereto. Any disclosure in addition to the Monthly Statement that is required to be included on Form 10-D (“Additional Form 10-D Disclosure”) shall be determined and prepared by and at the direction of the Depositor pursuant to the following paragraph, and the Securities Administrator will have no duty or liability for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure, except as set forth in the next paragraph.

As set forth on Exhibit N hereto, within 5 calendar days after the related Distribution Date of each month that the Trust is subject to the Exchange Act reporting requirements, (i) the parties set forth thereon shall be required to provide to the Securities Administrator and the Depositor, to the extent a Responsible Officer of such party has knowledge, in XXXXX-compatible form, or in such other format as otherwise agreed upon by the Securities Administrator and such party, a notice in the form of Exhibit R hereto (an “Additional Disclosure Notification”) together with, the form and substance of any Additional Form 10-D Disclosure, if applicable to such party and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Depositor will be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

After preparing the Form 10-D, but no later than the 12^th calendar day after the related Distribution Date, the Securities Administrator shall forward electronically a copy of the Form 10-D to the Depositor (provided that such Form 10-D includes any Additional Form 10-D Disclosure) for review. By the 13^th calendar day after the related Distribution Date, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-D. In the absence of any receipt of any written changes or approval from the Depositor by the 13^th calendar day after the related Distribution Date, the Securities Administrator shall be entitled to assume that such Form 10-D is in final form and the Securities Administrator may proceed with the execution and filing of the Form 10-D. A duly authorized representative of the Master Servicer shall sign the Form 10-D. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Securities Administrator will follow the procedures set forth in Section 11.04. Promptly (but no later than 1 Business Day) after filing with the Commission, the Securities Administrator will make available on its internet website a final executed copy of each Form 10-D prepared and filed by the Securities Administrator. Each party to this Agreement acknowledges that the performance by the Securities Administrator and the Master Servicer of its duties under this Section 11.01 related to the timely preparation, execution and filing of Form 10-D is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under this Section 11.01. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, timely execute and/or timely file such Form 10-D, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

Each of Form 10-D and Form 10-K requires the Depositor, as registrant, to indicate (by checking "yes" or "no") that it "(1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days." The Depositor hereby represents to the Securities Administrator that, as of the Closing Date, the Depositor has filed all such required reports during the preceding 12 months and that it has been subject to such filing requirement for the past 90 days. The Depositor shall notify the Securities Administrator in writing, no later than the fifth calendar day after the related Distribution Date with respect to the filing of a report on Form 10-D and no later than March 15th with respect to the filing of a report on Form 10-K, if the answer to such questions should be "no." The Securities Administrator shall be entitled to rely on such representations in preparing, executing and/or filing any such report.

SECTION 11.02

Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-K, where such failure results from the Securities Administrator’s inability or failure to obtain or receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

SECTION 11.03

(c)

The Holder hereof desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Certificate Registrar 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.]

[No transfer of a Certificate of this Class shall be made unless the Certificate Registrar, on behalf of the Trustee, shall have received either (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Certificate Registrar and the Trustee, to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code, nor a person acting on behalf of or investing plan assets of any such plan, which representation letter shall not be an expense of the Trust Fund, the Certificate Registrar, the Trustee, the Master Servicer, the Depositor or the Securities Administrator, (ii) if such certificate 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 which 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 95-60 (“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 Certificate presented for registration in the name of an employee benefit plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a trustee of any such plan or any other person acting on behalf of any such plan, an Opinion of Counsel satisfactory to the Certificate Registrar and the Trustee to the effect that the purchase or holding of such Certificate will not result in a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, will not result in the assets of the Trust Fund being deemed to be “plan assets” and subject to the prohibited transaction provisions of ERISA and the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, any Servicer, the Depositor or the Securities Administrator to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of the Trust Fund, the Certificate Registrar, the Trustee, the Master Servicer, the Depositor or the Securities Administrator. Notwithstanding anything else to the contrary herein, any purported transfer of a Certificate of this Class to or on behalf of an employee benefit plan subject to ERISA or to the Code without the opinion of counsel satisfactory to the Certificate Registrar and the Trustee as described above shall be void and of no effect.]

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually countersigned by an authorized signatory of the Securities Administrator.

We agree, on our own behalf and on behalf of any accounts for which we are acting as hereinafter stated, that if we should sell any Privately Offered Certificates within two years of the later of the date of original issuance of the Privately Offered Certificates or the last day on which such Privately Offered Certificates are owned by the Depositor or any affiliate of the Depositor we will do so only (A) to the Depositor, (B) to “qualified institutional buyers” (within the meaning of Rule 144A under the Securities Act) in accordance with Rule 144A under the Securities Act (“QIBs”), (C) pursuant to the exemption from registration provided by Rule 144 under the Securities Act, or (D) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is not a QIB (an “Institutional Accredited Investor”) which, prior to such transfer, delivers to the Certificate Registrar under the Pooling and Servicing Agreement, dated as of December 1, 2006, by and among X.X.

We further understand that the Privately Offered Certificates purchased by us will bear a legend to the foregoing effect.

(3)

We are acquiring the Privately Offered Certificates for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Privately Offered Certificates, and we and any account for which we are acting are each able to bear the economic risk of such investment.

(4)

We are an Institutional Accredited Investor and we are acquiring the Privately Offered Certificates purchased by us for our own account or for one or more accounts (each of which is an Institutional Accredited Investor) as to each of which we exercise sole investment discretion.

(5)

We have received such information as we deem necessary in order to make our investment decision.

(6)

If we are acquiring ERISA-Restricted Certificates, we understand that in accordance with ERISA, the Code and the Exemption, no Plan and no person acting on behalf of such a Plan may acquire such Certificate except in accordance with Section 3.03(d) of the Pooling and Servicing Agreement.
