This TRUST AGREEMENT dated as of March 1, 2006 (the “Agreement”), is between XXXXXX XXXXXXX CAPITAL I INC., a Delaware corporation, as depositor (the “Depositor”) and LASALLE BANK NATIONAL ASSOCIATION, a national banking association, as trustee (the “Trustee”) and acknowledged by XXXXXX XXXXXXX MORTGAGE CAPITAL INC., a New York corporation, as seller (the “Seller”), for purposes of Section 2.05.

WITNESSETH THAT

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

PRELIMINARY STATEMENT

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates. As provided herein, the Trustee will make multiple elections to treat a segregated pool of assets subject to this Agreement for federal income tax purposes as the following two separate real estate mortgage investment conduits (each, a “REMIC”): the Subsidiary REMIC and the Master REMIC. The Subsidiary REMIC will consist of the Mortgage Loans. The Subsidiary REMIC will issue the uncertificated REMIC regular interests specified below (each, a “Subsidiary REMIC Regular Interest”). The Subsidiary REMIC Regular Interests will represent the “regular interests” in the Subsidiary REMIC and the Class SR Interest will represent the single Class of “residual interest” in the Subsidiary REMIC.

The Trustee will hold the Subsidiary REMIC Regular Interest for the benefit of the Master REMIC. The Master REMIC will consist of the Subsidiary REMIC Interests and will be evidenced by the Certificates (other than the Class R Certificates), which will constitute the regular interests in the Master REMIC (the “Regular Certificates”) and the Class MR Interest, which will represent the single Class of “residual interest” in the Master REMIC. The Class R Certificates will represent the beneficial ownership of each of the Class SR and Class MR Interests. The “latest possible maturity date” for federal income tax purposes of all REMICs, and regular and residual interests created hereunder will be the Latest Possible Maturity Date.

Subsidiary REMIC

The Subsidiary REMIC Interests, each of which (except for the Class SR Interest) is hereby designated as a REMIC regular interest for federal income tax purposes, will have the principal balances, pass-through rates and Corresponding Master REMIC Certificates as set forth in the following table:

Subsidiary REMIC Interest	Initial Principal Balance	Interest Rate	Corresponding Master REMIC Certificate
S-A-1	(1)	(3)	Class A-1
S-M-1	(1)	(3)	Class M-1
S-M-2	(1)	(3)	Class M-2
S-M-3	(1)	(3)	Class M-3
S-B-1	(1)	(3)	Class B-1
S-B-2	(1)	(3)	Class B-2
S-B-3	(1)	(3)	Class B-3
S-B-4	(1)	(3)	Class B-4
S-B-5	(1)	(3)	Class B-5
S-Accrual	(1)	(3)	N/A
S-P	(2)	(4)	Class P
SR	(5)	(5)	N/A

_______________

(1)

For each Distribution Date, following the allocation of scheduled principal, prepayments and Realized Losses: (i) each such Class of Interests (other than the Class S-Accrual Interest) will have a principal balance equal to 50% of the principal balance in respect of the Corresponding Master REMIC Certificates, (ii) the Class S-Accrual Interest will have a principal balance equal to 50% of the principal balance of Mortgage Loans plus 50% of the Overcollateralized Amount.

(2)

For each Distribution Date, following the allocation of scheduled principal, prepayments and Realized Losses: each such Class of Interests will have a principal balance equal to 100% of the principal balance in respect of the Corresponding Class of Certificates.

(3)

The interest rate with respect to any Distribution Date (and the related Interest Accrual Period) for this REMIC Interest is a per annum rate equal to the Weighted Average Net Mortgage Rate of the Mortgage Loans.

(4)

The Class S-P Interest will not be entitled to any interest, but will be entitled to 100% of any prepayment premiums paid on the Mortgage Loans.

(5)

The SR Interest is the sole Class of residual interest in the Subsidiary REMIC. It pays no interest or principal.

The Master REMIC

The following table sets forth characteristics of the Master REMIC Certificates, together with the minimum denominations and integral multiples in excess thereof in which such Classes shall be issuable (except that one Certificate of each Class of Certificates may be issued in a different amount and, in addition, one Residual Certificate representing the Tax Matters Person Certificate may be issued in a different amount):

Class Designation	Initial Class Principal Balance	Pass-Through Rate (per annum)	Minimum Denomination⁽³⁾	Integral Multiples in Excess of Minimum⁽³⁾
Class A-1	$203,622,000.00	(1)	$25,000.00	$1,000.00
Class M-1	$31,104,000.00	(1)	$25,000.00	$1,000.00
Class M-2	$20,938,000.00	(1)	$25,000.00	$1,000.00

Class B-5	$3,948,740	(2)	$100,000.00	$1,000.00

(1)

Interest will accrue on each such Class of Certificates during each Interest Accrual Period at a rate equal to the lesser of (x) LIBOR plus the Pass-Through Margin for such Class for such Distribution Date and (y) the Net WAC Cap for such Distribution Date.

(2)

Interest will accrue on each such Class of Certificates during each Interest Accrual Period for each Distribution Date (i) occurring on or prior to the Initial Optimal Purchase Date at a rate equal to 7.000% per annum and (ii) occurring after the Initial Optimal Purchase Date at a rate equal to 7.500% per annum.

(3)

The minimum dollar denomination for any Certificate purchased by any Person within a Member State of the European Economic Area shall be $100,000.

(4)

The Class P Certificates will not be entitled to any interest, but will be entitled to 100% of any prepayment premiums paid on the Mortgage Loans. For the federal income tax purposes, the Class P Certificates will be entitled to 100% of the cash flow in respect of the Class S-P Interest.

(5)

The Class Principal Balance of the Class OC Certificates for any Distribution Date shall be equal to (x) the aggregate Stated Principal Balances of the Mortgage Loans as of such Distribution Date, minus (y) the aggregate Class Principal Balances of the other Certificates as of such Distribution Date. For purposes of compliance with the REMIC Provisions, the Class OC Certificates shall have an initial Certificate Balance equal to the Overcollateralized Amount as of the Closing Date.

(6)

For each Interest Accrual Period the Class OC Certificates shall accrue a specified portion of the interest on the Subsidiary REMIC Regular Interests equal to the excess of the Weighted Average Net Mortgage Rate of the Mortgage Loans over the product of two and the weighted average interest rate of the Subsidiary REMIC Regular Interests having “(1)” designated in the column entitled “Initial Principal Balance” with each such Class other than the Class S-Accrual Interest subject to a cap equal to the Pass-Through Rate of the corresponding Master REMIC class and the S-Accrual Interest subject to a cap of 0.00%. The Pass-Through Rate of the Class OC Certificates shall be a rate sufficient to entitle it to all interest accrued on the Mortgage Loans less the interest accrued on the other interests issued by the Master REMIC. The Class OC Distributable Amount for any Distribution Date is payable from current interest on the Mortgage Loans and any OC Release Amount for that Distribution Date.

(7)

The Class OC Certificates will be issued as a single Class of Certificates.

(8)

The Class R Certificates represent beneficial ownership of the sole Class of residual interest in each REMIC.

(9)

The Class R Certificates shall not be entitled to any interest.

(10)

The Class R Certificate shall be issued as two separate certificates, one with an initial Percentage Interest of 99.99 %and the Tax Matters Person Certificate with an initial Percentage Interest of 0.01%.

The foregoing provisions in the Preliminary Statement are intended to cause net interest and principal collections in respect of the Mortgage Loans to be distributed from the Subsidiary REMIC to the Master REMIC and from the Master REMIC to each Class of Certificates. The Preliminary Statement will be interpreted and applied consistently with such intent.

For any purpose for which the Pass-Through Rate is calculated, the interest rate on the Mortgage Loans shall be appropriately adjusted to account for the difference between the monthly day count convention of the Mortgage Loans and the monthly day count convention of the regular interests issued by each of the REMICs. For purposes of calculating the pass-through rates for each of the interests issued by the Subsidiary REMIC and the Master REMIC such rates shall be adjusted to equal a monthly day count convention based on the actual number of days elapsed in each Due Period and a 360-day year so that the Mortgage Loans and all regular interests will be using the same monthly day count convention.

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. With respect to a breach of a representation or warranty of by the related Originator under the related Purchase Agreement, if that Originator fails to cure the breach or repurchase the affected Mortgage Loan within the time period required by such Purchase Agreement, the Seller hereby agrees to honor that Originator’s cure obligations.

If pursuant to the foregoing provisions the related Originator or the Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the 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, the Originator or the Seller may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Replacement Mortgage Loans in the manner and subject to the limitations set forth in Section 2.05(c) 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.

(c)

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 Agreement, as modified by the related Acknowledgement, including all representations and warranties thereof included in such Purchase Agreement, 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 Servicer shall determine the excess (each, a “Substitution Adjustment 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 Servicer for deposit in the related Custodial Account an amount equal to the related Substitution Adjustment Amount, if any, and the related Custodian, on behalf of the Trustee, upon receipt of the related Replacement Mortgage Loan or Loans and certification by the 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, 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 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 cannot be delivered, then such substitution may only be effected at such time as the required Opinion of Counsel can be given.

(d)

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 Business Days give written notice thereof to the other parties. In connection therewith, the applicable Originator or the Seller shall repurchase or, subject to the limitations set forth in Section 2.05(c), 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(d) above and/or in accordance with this Section 2.05(d). 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 intermediate 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 intermediate transferee (but not the Trustee) 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).

ARTICLE III

THE CERTIFICATES

Section 3.01

The Certificates.

(a)

The Certificates shall be issuable 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 Balance, or in the Percentage Interests, specified herein. Each Class of Certificates will be issued in the minimum denominations and integral multiples thereof of the initial Certificate Balance specified in the Preliminary Statement hereto.

(b)

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer of the Trustee. Each Certificate shall, on original issue, be authenticated by the Authenticating Agent upon the order of the Depositor upon receipt by 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 or 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.

(c)

The Class OC, Class B-4, Class B-5, Class P and Class R Certificates offered and sold in reliance on the exemption from registration under Rule 144A under the Securities Act shall be issued initially in definitive, fully registered form without interest coupons with the applicable legends set forth in Exhibit A added to the forms of such Certificates (each, a “Restricted Global Security”).

Section 3.02

Registration.

The Trustee is hereby appointed, and the Trustee 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 (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 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 Trustee and the appointment of a successor Trustee. The Certificate Registrar may appoint, by a written instrument delivered to the Holders, 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.

Section 3.03

Transfer and Exchange of Certificates.

(a)

A 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 Certificate in accordance with the preceding sentence, 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 Balance as the Certificate being transferred. 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 Certificate 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 Balance 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. 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 Certificates are so surrendered for exchange, 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 to a transferee that takes delivery in the form of a Definitive 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 0000 Xxx) of the Depositor or (y) being made to a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Securities 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 Securities 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 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 Certificate Registrar and the Trustee 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 or the Depositor 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 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 or the Depositor 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 appropriate representation set forth in paragraph 2 and the representation set forth in paragraph 3 of 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 or the Depositor.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of the ERISA-Restricted Certificates to the Underwriter. 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 neither the Trustee nor 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 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 such time. Any such payments so recovered by the Trustee shall be paid and delivered by 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 (A) is 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 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 and the Certificate Registrar 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 Trustee or 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 Trustee or 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 Trustee or 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.

Neither the Certified Registrar nor the Trustee will have any responsibility for any aspect of the records relating to or payments made on account of beneficial ownership interests of the Book-Entry Certificates or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or transfers thereof.

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 Trustee or the Certificate Registrar or (ii) 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 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 Balance. 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 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 none of the Depositor, 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 order of the Depositor, 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 Trustee shall execute and the Authenticating Agent shall authenticate and deliver in exchange therefor a like aggregate Certificate Balance 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 is hereby appointed as the initial Paying Agent. The Trustee shall cause any Paying Agent, other than the Trustee, 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 Trustee 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 Trustee. If the Paying Agent is not the Trustee, 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 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 Trustee 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 (A) the Clearing Agency or the Depositor advises the Certificate Registrar 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 Certificate Registrar, 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 instruction of the Depositor, shall have the right to issue Definitive Certificates on the Closing Date in connection with credit enhancement programs.

(d)

On each Distribution Date and Initial Optional Purchase Date, the Trustee, as Paying Agent, shall withdraw from funds available in the Distribution Account and distribute the Available Funds to the Certificateholders and any other parties entitled thereto in the amounts and priorities set forth in Section 5.02. The Trustee may from time to time withdraw from the Distribution Account and pay itself, the related Custodian or the Servicer any amounts permitted to be paid or reimbursed to such Person from funds in the Distribution Account pursuant to this Agreement, any Purchase Agreement, the Servicing Agreement or the related Custodial Agreement.

(e)

Funds in the Distribution Account may be invested in Permitted Investments selected by and at the written direction of the Trustee, which shall mature not later than one Business Day prior to the Distribution Date (except that if such Permitted Investment is an obligation of the Trustee or any of its Affiliates, or is managed or advised by the Trustee or any Affiliate, then such Permitted Investment shall mature not later than such applicable Distribution Date) and any such Permitted Investment shall not be sold or disposed of prior to its maturity. All such Permitted Investments shall be made in the name of the Trustee (in its capacity as such) or its nominee. All income and gain realized from any Permitted Investment of amounts on deposit in the Distribution Account shall be for the benefit of the Trustee, as additional compensation for its duties hereunder, and shall be subject to its withdrawal or order from time to time, and shall not be part of the Trust Fund; provided, however, that if LaSalle Bank National Association is no longer the Trustee, any such income and gain shall be paid to the successor Trustee. The amount of any losses incurred in respect of any such investments shall be deposited in such Distribution Account by the Trustee out of its own funds, without any right of reimbursement therefor, immediately as realized.

Upon the occurrence of a default of which a Responsible Officer of the Trustee has actual knowledge under the Servicing Agreement, the Trustee, so long as any such default shall be continuing, 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 the Servicer pursuant to the applicable provisions of the Servicing Agreement; (ii) exercise any rights it may have to enforce the Servicing Agreement against the Servicer; and/or (iii) waive any such default under the Servicing Agreement or take any other action with respect to such default as is permitted thereunder; provided, however, that the Trustee shall not waive any default by the Servicer in making any P&I Advance required to be made by the Servicer under the Servicing Agreement.

(b)

Any termination by the Trustee of the Servicer’s rights and powers pursuant to the Servicing Agreement shall not be effected unless or until the Trustee shall have assumed all of the rights and obligations of the Servicer under the Servicing Agreement or shall have appointed, with the consent of the Rating Agencies and in accordance with the applicable provisions of the Servicing Agreement, a new Xxxxxx Xxx- or FHLMC-approved Person to serve as successor to the Servicer and such successor to the Servicer has accepted such appointment; 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. Upon appointment of a successor servicer, as authorized under this Section 4.03(b), unless the successive servicer shall have assumed the obligations of the terminated Servicer under the Servicing Agreement, the Trustee and such successor servicer shall enter into a servicing agreement in a form substantially similar to the affected Servicing Agreement. In connection with any such appointment, the Trustee 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 be in excess of that payable to the Servicer under the Servicing Agreement. If the Trustee assumes the servicing of the Mortgage Loans, it will not assume liability for the representations or warranties of the Servicer it replaces or for the actions, errors or omissions of such Servicer.

The Depositor shall cause the Seller to give reasonable prior written notice to the Trustee if the initial Servicing Transfer Date changes. The Depositor shall cause the costs of such transfer (including any costs of the Trustee) to be borne by the Seller.

The Depositor shall not consent to the assignment by the Servicer of the Servicer’s rights and obligations under the Servicing Agreement without the prior written consent of the Trustee, which consent shall not be unreasonably withheld.

The Trustee shall execute and deliver, at the written request of the Servicer, and furnish to the Servicer, at the expense of the requesting party, a power of attorney in the standard form provided by the Trustee to take title to the Mortgaged Properties after foreclosure in the name of and on behalf of the Trustee and for the purposes described herein to the extent necessary or desirable to enable the Servicer to perform its duties.

the Available Distribution Amount, the Interest Remittance Amount, the Principal Distribution Amount applicable to such Distribution Date;

(p)

if applicable, the amount of any shortfall (i.e., the difference between the aggregate amounts of principal and interest which Certificateholders would have received if there were sufficient available amounts in the Distribution Account and the amounts actually distributed);

(q)

the Overcollateralized Amount after giving effect to the distributions made on such Distribution Date;

(r)

the amount of any Overcollateralization Increase Amount after giving effect to the distributions made on such Distribution Date; and

(s)

the level of LIBOR for such Distribution Date and the level of LIBOR for the following Distribution Date.

The Trustee shall make such reports available each month via its website at xxx.xxxxxxxx.xxx. Assistance in using the website may be obtained by calling the Trustee’s customer service desk at (000) 000-0000. Certificateholders and other parties that are unable to use the website are entitled to have a paper copy mailed to them via first class mail by contacting the Trustee and indicating such. In preparing or furnishing the foregoing reports, the Trustee shall be entitled to rely conclusively on the accuracy of the information or data regarding the Mortgage Loans and the related REO Properties that has been provided to the Trustee by the Servicer, without any independent investigation, and the Trustee shall not be obligated to verify, recompute, reconcile or recalculate any such information or data.

Upon the reasonable advance written request of any Certificateholder that is a savings and loan, bank or insurance company, the Trustee shall provide, or cause to be provided, (or, to the extent that such information or documentation is not required to be provided by the Servicer under the Servicing Agreement, shall use reasonable efforts to obtain such information and documentation from the Servicer, and provide) to such Certificateholders such reports and access to information and documentation regarding the Mortgage Loans as such Certificateholders may reasonably deem necessary to comply with applicable regulations of the Office of Thrift Supervision or its successor or other regulatory authorities with respect to an investment in the Certificates; provided, however, that the Trustee shall be entitled to be reimbursed by such Certificateholders for the Trustee’s actual expenses incurred in providing such reports and access.

(b) For all purposes of this Agreement, with respect to any Mortgage Loan, delinquencies shall be determined and reported based on the so-called “OTS” methodology for determining delinquencies on mortgage loans similar to the Mortgage Loans. By way of example, a Mortgage Loan would be delinquent with respect to a Scheduled Payment due on a Due Date if such Scheduled Payment is not made by the close of business on the Mortgage Loan’s next succeeding Due Date, and a Mortgage Loan would be more than 30-days Delinquent with respect to such Scheduled Payment if such Scheduled Payment were not made by the close of business on the Mortgage Loan’s second succeeding Due Date. The Servicer hereby represents and warrants to the Depositor that this delinquency recognition policy is not less restrictive than any delinquency recognition policy established by the primary safety and soundness regulator, if any, of the Servicer.

Section 4.05

Annual Statement of Compliance.

(a) Not later than March 15th of each calendar year commencing in 2007, the Trustee and the Custodian shall deliver, and the Trustee shall cause each Subcontractor utilized by the Trustee and determined by the Trustee to be “participating in a servicing function” within the meaning of Item 1122 of Regulation AB (in each case, a “Servicing Function Participant”), to deliver, each at its own expense, to the Depositor and the Trustee, a report on an assessment of compliance with the Servicing Criteria applicable to it that contains (A) a statement by such party of its responsibility for assessing compliance with the Servicing Criteria applicable to it, (B) a statement that such party used the Servicing Criteria to assess compliance with the applicable Servicing Criteria, (C) such party’s assessment of compliance with the applicable Servicing Criteria as of and for the period ending the end of the fiscal year covered by the Form 10-K required to be filed pursuant to Section 6.14 of the Trust Agreement, including, if there has been any material instance of noncompliance with the applicable Servicing Criteria, a discussion of each such failure and the nature and status thereof, and (D) a statement that a registered public accounting firm has issued an attestation report on such Person’s assessment of compliance with the applicable Servicing Criteria as of and for such period. Each such assessment of compliance report shall be addressed to the Depositor and signed by an authorized officer of the applicable company, and shall address each of the applicable Servicing Criteria set forth on Exhibit N hereto, or as set forth in the notification furnished to the Depositor and the Trustee pursuant to Section 4.05(c). The Trustee and the Custodian hereby acknowledge and agree that their respective assessments of compliance will cover the items identified on Exhibit N hereto are being covered by such party. Promptly after receipt of each such report on assessment of compliance, (i) the Depositor shall review each such report and, if applicable, consult with the Trustee or the Custodian, as applicable, Servicer as to the nature of any material instance of noncompliance with the Servicing Criteria (and Servicing Function Participant engaged or utilized by the Trustee), as the case may be. None of the Trustee, the Custodian or Servicing Function Participant shall be required to cause the delivery of any such assessments if it has received written confirmation from the Depositor that a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year.

(b) Not later than March 15th of each calendar year commencing in 2007, the Trustee and the Custodian shall cause, and the Trustee shall cause each Servicing Function Participant utilized by the Trustee to cause, each at its own expense, a registered public accounting firm (which may also render other services to such party) and that is a member of the American Institute of Certified Public Accountants to furnish a report to the Trustee and the Depositor, with a copy to the Rating Agencies, to the effect that (i) it has obtained a representation regarding certain matters from the management of such Person, which includes an assertion that such Person has complied with the Servicing Criteria applicable to it and (ii) on the basis of an examination conducted by such firm in accordance with standards for attestation engagements issued or adopted by the PCAOB, that attests to and reports on such Person’s assessment of compliance with the Servicing Criteria applicable to it. In the event that an overall opinion cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Each such related accountant’s attestation report shall be made in accordance with Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and the Exchange Act. Such report must be available for general use and not contain restricted use language. Promptly after receipt of each such accountants’ attestation report, the Depositor shall review the report and, if applicable, consult with the Trustee or the Custodian, as applicable, as to the nature of any defaults by the Trustee or the Custodian, as applicable, (and each Servicing Function Participant engaged or utilized by the Trustee), as the case may be, in the fulfillment of any of the Trustee’s, the Custodian’s or the applicable Servicing Function Participant’s obligations hereunder. None of the Trustee or the Custodian or the Servicing Function Participant shall be required to cause the delivery of any such attestation required by this paragraph in any year in which a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year.

(c) No later than February 1 of each fiscal year, commencing in 2007, in which a Form 10-K will be required to be filed in respect of the Trust for the preceeding calendar year, the Trustee shall notify the Depositor as to the name of each Servicing Function Participant utilized by it, and each such notice will specify what specific Servicing Criteria will be addressed in the report on assessment of compliance prepared by such Servicing Function Participant in each case, to the extent of any change from the prior year’s notice, if any. When the Trustee submits its assessment pursuant to Section 4.05(a), the Trustee will also at such time include the assessment (and related attestation pursuant to Section 4.05(b)) of each Servicing Function Participant utilized by it.

Section 4.06

Regulation AB Compliance, Intent of the Parties; Reasonableness.

The parties hereto acknowledge that interpretations of the requirements of Regulation AB may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants in the asset-backed securities markets, advice of counsel, or otherwise, and agree to comply with requests made by the Depositor in good faith for delivery of information under these provisions on the basis of evolving interpretations of Regulation AB. In connection with the Trust, the Trustee, at the expense of the Depositor, shall cooperate fully with the Depositor to deliver to the Depositor (including its assignees or designees), any and all statements, reports, certifications, records and any other information available to the Trustee and reasonably necessary in the good faith determination of the Depositor to permit the Depositor to comply with the provisions of Regulation AB, together with such disclosures relating to the Trustee or Servicing Function Participant engaged by it, reasonably believed by the Depositor to be necessary in order to effect such compliance.

ARTICLE V

DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

Section 5.01

Distributions Generally.

(a)

Subject to Section 7.01 respecting the final distribution on the Certificates, on each Distribution Date the Trustee or the Paying Agent shall make all distributions in accordance with this Article V. Such distributions shall be made by check mailed to each Certificateholder’s address as it appears on the Certificate Register of the Certificate Registrar or, upon written request made to the Trustee at least five Business Days prior to the related Record Date by any Certificateholder owning an aggregate initial Certificate Balance of at least $1,000,000, by wire transfer in immediately available funds to an account specified in the request and at the expense of such Certificateholder; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Certificate Registrar’s Corporate Trust Office; provided, further, that the foregoing provisions shall not apply to any Class of Certificates as long as such Certificate remains a Book-Entry Certificate in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding the reduction of the Class Principal Balance of any Class of Certificates to zero, such Class will be outstanding hereunder (solely for the purpose of receiving distributions and not for any other purpose) until the termination of the respective obligations and responsibilities of the Depositor and the Trustee hereunder in accordance with Article VII. Wire transfers will be made at the expense of the Holder requesting such wire transfer by deducting a wire transfer fee from the related distribution. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of each REMIC and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Certificate Registrar’s Corporate Trust Office. If any payment required to be made on the Certificates is to be made on a day that is not a Business Day, then such payment will be made on the next succeeding Business Day.

(b)

All distributions or allocations made with respect to the Certificateholders within each Class on each Distribution Date shall be allocated among the outstanding Certificates in such Class equally in proportion to their respective initial Class Principal Balances or Percentage Interests.

Section 5.02

(xx)

to the Class OC Certificates, the Class OC Distributable Amount; and

(xxi)

to the holders of the Class R Certificates, any remaining amounts; provided that if such Distribution Date is the Distribution Date immediately following the expiration of the latest Prepayment Penalty term or any Distribution Date thereafter, then any such remaining amounts, together with the Class P Distribution Amount, will be distributed first, to the holders of the Class P Certificates, until the Class Principal Balance thereof has been reduced to zero; and second, to the holders of the Class R Certificates.

For the avoidance of doubt, Section 5.02(c) is intended to cause the Class OC Certificates to receive from amounts remaining after the application of all other clauses of Section 5.02(c) preceding it, an amount up to the sum of the Class OC Distributable Amount for that Distribution Date and any Class OC Distributable Amounts remaining unpaid from prior Distribution Dates and the Trustee shall construe Section 5.02(c) as necessary so as to accomplish such result.

Section 5.03

Allocation of Losses.

(a)

On or prior to each Distribution Date, the Trustee shall aggregate the information provided by the Servicer with respect to the total amount of Realized Losses for the related Distribution Date.

(b)

Any Applied Loss Amounts on the Mortgage Loans shall be allocated to the Subordinated Certificates in reverse order of their respective priorities of payment (beginning with the Class of Class B Certificates then outstanding with the highest numerical Class designation or, if no Classes of Class B Certificates are outstanding, then beginning with the Class of Class M Certificates then outstanding with the highest numerical Class designation) until the respective Class Principal Balance of each such Class is reduced to zero.

(c)

The Class Principal Balance of the Class of Subordinated Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the Applied Loss Amount, if any. For the avoidance of doubt, no reductions will be made in the Class Principal Balance of the Senior Certificates in respect of Realized Losses on the Mortgage Loans.

(d)

Any Applied Loss Amounts allocated to a Class of Certificates or any reduction in the Class Principal Balance of a Class of Certificates pursuant to Section 5.03(b) above shall be allocated among the Certificates of such Class in proportion to their respective Certificate Balances.

(e)

Any allocation of Realized Losses to a Certificate or any reduction in the Certificate Balance of a Certificate, pursuant to Section 5.03(b) above shall be accomplished by reducing the Certificate Balance thereof immediately following the distributions made on the related Distribution Date in accordance with the definition of “Certificate Balance.”

(f)

For the avoidance of doubt, no Realized Losses on the Mortgage Loans shall be allocated to the Class P Certificates.

(g)

In the event of any Subsequent Recoveries, (i) such amount shall be treated as a Principal Prepayment and shall be included in the Available Distribution Amount for the Distribution Date occurring in the month following the month in which such recovery is received and (ii) the Certificate Balance of the Class or Classes to which the related Realized Loss had previously been allocated, whether or not such Class or Classes remain outstanding, shall be increased in direct order of priority, in each case by an amount equal to the lesser of (x) the amount of such recovery and (y) the aggregate amount of Realized Losses previously allocated to such Classes less amounts previously allocated to such Classes pursuant to this paragraph.

Section 5.04

Determination of Pass-Through Rates for LIBOR Certificates.

(a)

On each Interest Determination Date after the initial Interest Determination Date and for so long as any LIBOR Certificates are outstanding, the Trustee will determine LIBOR on the basis of the British Bankers’ Association (“BBA”) “Interest Settlement Rate” for one-month deposits in U.S. dollars as found on Telerate page 3750 as of 11:00 a.m. London time on each LIBOR Determination Date. “Telerate Page 3750” means the display page currently so designated on the Moneyline Telerate Service (formerly the Dow Xxxxx Markets) (or such other page as may replace that page on that service for the purpose of displaying comparable rates or prices).

(b)

If on any Interest Determination Date, LIBOR cannot be determined as provided in paragraph (a) of this Section 5.05, the Trustee shall either (i) request each Reference Bank to inform the Trustee of the quotation offered by its principal London office for making one-month United States dollar deposits in leading banks in the London interbank market, as of 11:00 a.m. (London time) on such Interest Determination Date or (ii) in lieu of making any such request, rely on such Reference Bank quotations that appear at such time on the Reuters Screen LIBO Page (as defined in the International Swap Dealers Association Inc. Code of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition), to the extent available. LIBOR for the next Interest Accrual Period will be established by the Trustee on each interest Determination Date as follows:

(i)

If on any Interest Determination Date two or more Reference Banks provide such offered quotations, LIBOR for the next applicable Interest Accrual Period shall be the arithmetic mean of such offered quotations (rounding such arithmetic mean upwards if necessary to the nearest whole multiple of 1/32%).

(ii)

If on any Interest Determination Date only one or none of the Reference Banks provides such offered quotations, LIBOR for the next Interest Accrual Period shall be whichever is the higher of (i) LIBOR as determined on the previous Interest Determination Date or (ii) the Reserve Interest Rate. The “Reserve Interest Rate” shall be the rate per annum which the Trustee determines to be either (i) the arithmetic mean (rounded upwards if necessary to the nearest whole multiple of 1/32%) of the one-month United States dollar lending rates that New York City banks selected by the Trustee are quoting, on the relevant Interest Determination Date, to the principal London offices of at least two of the Reference Banks to which such quotations are, in the opinion of the Trustee, being so made, or (ii) in the event that the Trustee can determine no such arithmetic mean, the lowest one-month United States dollar lending rate which New York City banks selected by the Trustee are quoting on such Interest Determination Date to leading European banks.

(iii)

If on any Interest Determination Date the Trustee is required but is unable to determine the Reserve Interest Rate in the manner provided in paragraph (b) above, LIBOR for the related Classes of Certificates shall be LIBOR as determined on the preceding applicable Interest Determination Date.

(iv)

In the case of the first Distribution Date, LIBOR shall be 4.7837%.

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

(c)

The Pass-Through Rate for each Class of LIBOR Certificates for each Interest Accrual Period shall be determined by the Trustee on each Interest Determination Date so long as the LIBOR Certificates are outstanding on the basis of LIBOR and the respective formulae appearing in footnotes corresponding to the LIBOR Certificates in the table relating to the Certificates in the Preliminary Statement.

(d)

In determining LIBOR, any Pass-Through Rate for the LIBOR Certificates, any Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may conclusively rely and shall be protected in relying upon the offered quotations (whether written, oral or on the Dow Xxxxx Markets) from the BBA designated banks, the Reference Banks or the New York City banks as to LIBOR, the Interest Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from time to time. The Trustee shall not have any liability or responsibility to any Person for (i) the selection of New York City banks for purposes of determining any Reserve Interest Rate or (ii) its inability, following a good-faith reasonable effort, to obtain such quotations from, the BBA designated banks, the Reference Banks or the New York City banks or to determine such arithmetic mean, all as provided for in this Section 5.04.

(e)

The establishment of LIBOR and each Pass-Through Rate for the LIBOR Certificates by the Trustee shall (in the absence of manifest error) be final, conclusive and binding upon each Holder of a Certificate and the Trustee.

(h)

The Trustee shall not be liable in its individual capacity for an error of judgment made in good faith by a Responsible Officer or other officers of the Trustee unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts.

Notwithstanding anything in this Agreement to the contrary, the Trustee shall not be liable for special, indirect or consequential losses or damages of any kind whatsoever (including, but not limited to, lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

For all purposes under this Agreement, the Trustee shall not be deemed to have any notice of any event of default under a Servicing Agreement unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Holders of the Certificates and this Agreement.

(iii)

no trustee or custodian hereunder shall be personally liable by reason of any act or omission of any other trustee or custodian hereunder; and

(c)

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them.

Authenticating Agents.

(a)

The Trustee may appoint one or more Authenticating Agents which shall be authorized to act on behalf of the Trustee in authenticating Certificates. In the absence of any such appointment, references herein to the Authenticating Agent shall mean the Trustee. Wherever reference is made in this Agreement to the authentication of Certificates by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent must be a corporation organized and doing business under the laws of the United States of America or of any state, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities.

Section 6.12

Section 6.14

Periodic Filings

(a) The Trustee shall reasonably cooperate with the Depositor in connection with the reporting requirements of the Trust under the Exchange Act. The Trustee shall prepare for execution by the Depositor any Forms 8-K (other than the initial report on Form 8-K), 10-D and 10-K required by the Exchange Act and the rules and regulations of the Commission thereunder, in order to permit the timely filing thereof pursuant to the terms of this Section 6.14, and the Trustee shall file (via the Commission’s Electronic Data Gathering and Retrieval System) such Forms executed by the Depositor. The Trustee shall have no duty to verify information received by it from other Persons (other than Subcontractors utilized by the Trustee) in connection with its duties under this Section 6.14.

(b) Within 15 calendar days after each Distribution Date (subject to permitted extensions under the Exchange Act), the Trustee shall prepare and file on behalf of the Trust any Form 10-D required by the Exchange Act, in form and substance as required by the Exchange Act. The Trustee 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 prepared by the party responsible for preparing such disclosure as set forth on Exhibit O hereto and the Trustee shall compile such disclosure pursuant to the following paragraph. The Trustee will have no duty or liability for any failure hereunder to determine, prepare or file any Additional Form 10-D Disclosure, except as set forth in the next paragraph.

As set forth on Exhibit O hereto, within 5 calendar days after the related Distribution Date, certain parties to this Agreement shall be required to provide to the Trustee and the Depositor, to the extent known by such applicable parties, any Additional Form 10-D Disclosure, if applicable. In addition, the Servicer is obligated under the Servicing Agreement to provide certain information to the Trustee. The Trustee shall compile all such information provided to it in a Form 10-D prepared by it.

After preparing the Form 10-D, the Trustee shall forward electronically a draft copy of the Form 10-D to the Depositor for review, verification and execution by the Depositor. No later than 2 Business Days prior to the 15th calendar day after the related Distribution Date, an officer of the Depositor shall sign the Form 10-D and return an electronic or fax copy of such signed Form 10-D (with an original executed hard copy to follow by overnight mail) to the Trustee. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Trustee will follow the procedures set forth in Section 6.14(f)(ii). The signing party at the Depositor can be contacted at the Depositor’s address for notices set forth in Section 10.07, or such other address as to which the Depositor has provided prior written notice to the Trustee. The Depositor acknowledges that the performance by the Trustee of its duties under this Section 6.14(b) related to the timely preparation and filing of Form 10-D is contingent upon the Servicer, the Depositor and any other Person obligated to provide Additional Form 10-D Disclosure as set forth on Exhibit O hereto observing all applicable deadlines in the performance of their duties under this Section 6.14(b) or the applicable provisions of the Servicing Agreement. The Trustee shall have no liability for any loss, expense, damage, or claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-D, where such failure results from the Trustee’s inability or failure to obtain or receive, on a timely basis, any information from any party hereto or the Servicer or Custodian (other than the Trustee or any Subcontractor utilized by the Trustee) needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

(c) Within 90 days after the end of each fiscal year of the Trust or such earlier date as may be required by the Exchange Act (the “10-K Filing Deadline”), commencing in March 2007, the Trustee shall prepare and file on behalf of the Trust a Form 10-K, in form and substance as required by the Exchange Act. Each such Form 10-K shall include the following items, in each case to the extent they have been delivered to the Trustee within the applicable time frames set forth in this Agreement, (i) an annual compliance statement for the Servicer, and each Subservicer engaged by the Servicer, and the Trustee, (ii)(A) the annual reports on assessment of compliance with servicing criteria for the Trustee, the Servicer, the Custodian, each Subservicer engaged by the Servicer and each Servicing Function Participant utilized by the Servicer or the Trustee, and (B) if any such report on assessment of compliance with servicing criteria identifies any material instance of noncompliance, disclosure identifying such instance of noncompliance, or such report on assessment of compliance with servicing criteria is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not included, (iii)(A) the registered public accounting firm attestation report for the Trustee, the Servicer, the Custodian, each Subservicer engaged by the Servicer and each Servicing Function Participant utilized by the Servicer, or the Trustee, and (B) if any registered public accounting firm attestation report identifies any material instance of noncompliance, disclosure identifying such instance of noncompliance, or if any such registered public accounting firm attestation report is not included as an exhibit to such Form 10-K, disclosure that such report is not included and an explanation why such report is not included, and (iv) a certification in the form attached hereto as Exhibit L, with such changes as may be necessary or appropriate as a result of changes promulgated by the Commission (the “Sarbanes Certification”), which shall be signed by the senior officer of the Depositor in charge of securitization. Any disclosure or information in addition to (i) through (iv) above that is required to be included on Form 10-K (“Additional Form 10-K Disclosure”) shall be prepared by party responsible for preparing such disclosure as set forth on Exhibit P hereto, and the Trustee shall compile such disclosure pursuant to the following paragraph. The Trustee will have no duty or liability for any failure hereunder to determine or prepare any Additional Form 10-K Disclosure, except as set forth in the next paragraph.

As set forth on Exhibit P hereto, no later than March 15th of each year that the Trust is subject to the Exchange Act reporting requirements, commencing in 2007, certain parties to this Agreement and the Servicer and the Custodian shall be required to provide to the Trustee and the Depositor, to the extent known by such applicable parties, any Additional Form 10-K Disclosure, if applicable. In addition, the Servicer is obligated under the Servicing Agreement to provide certain information to the Trustee. The Trustee shall compile all such information provided to it in a Form 10-K prepared by it.

After preparing the Form 10-K, the Trustee shall forward electronically a draft copy of the Form 10-K to the Depositor for review, verification and execution by the Depositor. No later than 5:00 p.m. EST on the 3rd Business Day prior to the 10-K Filing Deadline, an officer of the Depositor shall sign the Form 10-K and return an electronic or fax copy of such signed Form 10-K (with an original executed hard copy to follow by overnight mail) to the Trustee. If a Form 10-K cannot be filed on time or if a previously filed Form 10-K needs to be amended, the Trustee will follow the procedures set forth in Section 6.14(f)(ii). The signing party at the Depositor can be contacted at the Depositor’s address for notices set forth in Section 10.07, or such other address as to which the Depositor has provided prior written notice to the Trustee. The Depositor acknowledges that the performance by the Trustee of its duties under this Section 6.14(c) related to the timely preparation and filing of Form 10-K is contingent upon the Servicer (and any Subservicer or Servicing Function Participant engaged by the Servicer) and the Depositor and any other Person obligated to provide Additional Form 10-K Disclosure as set forth on Exhibit P hereto, observing all applicable deadlines in the performance of their duties under this Section 6.14(c), Section 6.14(d), or the applicable provisions of the Servicing Agreement. The Trustee shall have no liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-K, where such failure results from the Trustee’s inability or failure to obtain or receive, on a timely basis, any information from any party hereto (other than the Trustee or any Subcontractor utilized by the Trustee) needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

(d) In connection with the execution of a Sarbanes Certification, the Trustee shall sign a certification (in the form attached hereto as Exhibit M, with such changes as may be necessary or appropriate as a result of changes promulgated by the Commission) for the benefit of the Depositor and its officers, directors and Affiliates, and the Servicer shall sign a certification solely with respect to the Servicer (in the form attached to the Servicing Agreement, with such changes as may be necessary or appropriate as a result of changes promulgated by the Commission) for the benefit of the Depositor, the Trustee and their respective officers, directors and Affiliates. Each such certification shall be delivered to the Depositor no later than March 10th of each year (or if such day is not a Business Day, the immediately preceding Business Day) and the Depositor shall deliver the Sarbanes Certification no later than the time set forth for the delivery to the Trustee of the signed Form 10-K pursuant to Section 6.14(d) for such year). In the event that prior to the filing date of the Form 10-K in March of each year, the Trustee or the Servicer has actual knowledge of information material to the Sarbanes Certification, that party shall promptly notify the Depositor and each of the other parties signing the certifications. In addition, the Trustee shall indemnify and hold harmless the Depositor and the Sponsor and their officers, directors, employees, agents and Affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon any breach of the Trustee’s obligations under this Section 6.14(d) or any material misstatement or material omission contained in any information, report, certification or other material provided by the Trustee in written or electronic form pursuant to Section 6.14 of this Agreement and Exhibits O, P and Q to this Agreement provided by the Trustee (excluding any information, report, accountants’ letter, certification or other materials provided in written or electronic form by or on behalf of any Person other than the Trustee or any Subcontractor utilized by the Trustee), which results from negligence, bad faith or willful misconduct on the part of the Trustee in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless any indemnified party, then the Trustee agrees in connection with a breach of the Trustee’s obligations under this Section 6.14(d) or any material misstatement or material omission contained in any information, report, certification, or other material provided in written or electronic form pursuant to Section 6.14 of this Agreement and Exhibits O, P and Q to this Agreement provided by or on behalf of the Trustee (excluding any information, report, certification, accountants’ letter or other materials provided in written or electronic form by or on behalf of any Person other than the Trustee or any Subcontractor utilized by the Trustee), results from negligence, bad faith or willful misconduct on the part of the Trustee in connection therewith that it shall contribute to the amount paid or payable by the Depositor and the Sponsor as a result of the losses, claims, damages or liabilities of the Depositor and the Sponsor in such proportion as is appropriate to reflect the relative fault of the Depositor and the Sponsor on the one hand and the Trustee on the other.

(e) Upon any filing with the Commission, the Trustee shall promptly deliver to the Depositor a copy of each such executed report, statement or information.

(f) (i) The obligations set forth in paragraphs (a) through (d) of this Section shall only apply with respect to periods for which reports are required to be filed with respect to the Trust under the Exchange Act. Prior to January 30 of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15 Suspension Notification with respect to the Trust, with a copy to the Depositor. At any time after the filing of a Form 15 Suspension Notification, if the number of Holders of the Offered Certificates of record exceeds the number set forth in Section 15(d) of the Exchange Act or the regulations promulgated pursuant thereto which would cause the Trust to again become subject to the reporting requirements of the Exchange Act, the Trustee shall recommence preparing and filing reports on Form 10-K, 10-D and 8-K as required pursuant to this Section 6.14 and the parties hereto shall again have the obligations set forth in this Section, in Section 12 of the Custodial Agreement and Section 5.04 of the Servicing Agreement.

(ii) In the event that the Trustee is unable to timely file with the Commission all or any required portion of any Form 8-K, 10-D or 10-K required to be filed pursuant to this Agreement because required disclosure information was either not delivered to it or delivered to it after the delivery deadlines set forth in this Agreement, the Trustee will immediately notify the Depositor and the Servicer. In the case of Form 10-D and 10-K, the Depositor, the Servicer and the Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a 10-DA and 10-KA as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Trustee will, upon receipt of all disclosure information required to be included on Form 8-K, include such disclosure information on the next Form 10-D. In the event that any previously filed Form 8-K, 10-D or 10-K needs to be amended, the party to this Agreement deciding that an amendment to such Form 8-K, 10-D or 10-K is required will notify the Depositor, the Trustee and the Servicer and such parties will cooperate to prepare any necessary Form 8-KA, 10-DA or 10-KA. Any Form 15, Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K shall be signed by an officer of the Depositor. The Depositor acknowledges that the performance by the Trustee of its duties under this Section 6.14(f) related to the timely preparation and filing of Form 15, a Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent upon the Servicer, the Depositor observing all applicable deadlines in the performance of their duties under this Section 6.14 or the applicable provisions of the Servicing Agreement. The Trustee shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file any such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, where such failure results from the Trustee’s inability or failure to obtain or receive, on a timely basis, any information from the Depositor, the Servicer or the Custodian (other than the Trustee or any Subcontractor utilized by the Trustee) needed to prepare, arrange for execution or file such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from its own negligence, bad faith or willful misconduct.

(g) Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such event, a “Reportable Event”), and also if requested by the Depositor, the Trustee shall prepare and file on behalf of the Trust any Form 8-K, as required by the Exchange Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates. Any disclosure or information related to a Reportable Event or that is otherwise required to be included on Form 8-K (“Form 8-K Disclosure Information”) shall be prepared by the party responsible for preparing such disclosure as set forth on Exhibit Y hereto and compiled by the Trustee pursuant to the following paragraph. The Trustee will have no duty or liability for any failure hereunder to determine or prepare any Form 8-K Disclosure Information or any Form 8-K, except as set forth in the next paragraph.

As set forth on Exhibit Q hereto, for so long as the Trust is subject to the Exchange Act reporting requirements, no later than noon on the 2nd Business Day after the occurrence of a Reportable Event, certain parties to this Agreement and the Servicer under the Servicing Agreement shall be required to provide to the Depositor and the Trustee, to the extent known by such applicable parties, any Form 8-K Disclosure Information, if applicable. In addition, the Servicer is obligated under the Servicing Agreement to provide certain information to the Trustee. The Trustee shall compile all such information provided to it in a Form 8-K prepared by it.

After preparing the Form 8-K, the Trustee shall forward electronically a draft copy of the Form 8-K to the Depositor for review, verification and execution by the Depositor. No later than the end of the 3rd Business Day after the Reportable Event, an officer of the Depositor shall sign the Form 8-K and return an electronic or fax copy of such signed Form 8-K (with an original executed hard copy to follow by overnight mail) to the Trustee. If a Form 8-K cannot be filed on time or if a previously filed Form 8-K needs to be amended, the Trustee will follow the procedures set forth in Section 6.14(f)(ii). The signing party at the Depositor can be contacted at the Depositor’s address for notices set forth in Section 10.07, or such other address as to which the Depositor has provided prior written notice to the Trustee. The Depositor acknowledges that the performance by the Trustee of its duties under this Section 6.14(g) related to the timely preparation and filing of Form 8-K is contingent upon the Servicer, the Depositor and any other Person obligated to provide Form 8-K Disclosure Information as set forth on Exhibit Q hereto, observing all applicable deadlines in the performance of their duties under this Section 6.14(g). The Trustee shall have no liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 8-K, where such failure results from the Trustee’s inability or failure to obtain or receive, on a timely basis, any information from any party hereto (other than the Trustee or any Subcontractor utilized by the Trustee) needed to prepare, arrange for execution or file such Form 8-K, not resulting from its own negligence, bad faith or willful misconduct.

(h) The Trustee shall have no liability for any loss, expense, damage or claim arising out of or resulting from (i) the accuracy or inaccuracy of any Additional Form 10-D Disclosure, Additional Form 10-K Disclosure or Form 8-K Disclosure Information (excluding any information therein provided by the Trustee or any Subcontractor utilized by the Trustee) provided to the Trustee in connection with the preparation of Forms 10-D, 10-K and 8-K pursuant to this Section 6.14, or (ii) the failure of the Depositor to timely execute and return for filing any Forms 10-D, 10-K and 8-K required to be filed by the Trustee pursuant to this Section 6.14, in either case, not resulting from the Trustee’s own negligence, bad faith or misconduct.

ARTICLE VII

PURCHASE OF MORTGAGE LOANS AND
TERMINATION OF THE TRUST FUND

Section 7.01

Purchase of Mortgage Loans; Termination of Trust Fund Upon Purchase or Liquidation of All Mortgage Loans.

(a)

The obligations and responsibilities of the Trustee created hereby (other than the obligation of the Trustee 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 sale or auction of the property held by the Trust Fund in accordance with Section 7.01(b) or 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)

On the Initial Optional Termination Date, the Auction Administrator shall solicit bids for the Pool Assets from at least three institutions that are regular purchasers and/or sellers in the secondary market of residential whole mortgage loans similar to the Mortgage Loans. If the Auction Administrator receives at least three bids for the Pool Assets, and one of such bids is equal to or greater than the Minimum Auction Price, the Auction Administrator shall sell the related Pool Assets to the highest bidder (the “Auction Purchaser”) at the price offered by the Auction Purchaser (the “Mortgage Loan Auction Price”). If the Auction Administrator receives less than three bids, or does not receive any bid that is at least equal to the Minimum Auction Price, unless the Servicer exercises its option under subsection (c) below, the Auction Administrator shall, on each six-month anniversary of the initial Optional Termination Date, repeat these auction procedures until the Auction Administrator receives a bid that is at least equal to the Minimum Auction Price, at which time the Auction Administrator shall sell the Pool Assets to the Auction Purchaser at that Mortgage Loan Auction Price; provided, however, that the Auction Administrator shall not be required to repeat these auction procedures on any Distribution Date for any six-month anniversary of the initial Optional Termination Date unless the Auction Administrator reasonably believes that there is a reasonable likelihood of receiving a bid of at least the Minimum Auction Price. The Auction Administrator shall give notice to the Rating Agencies and the Servicer that is servicing any of the Mortgage Loans of the sale of the Pool Assets pursuant to this Section 7.01(b) (an “Auction Sale”) and of the date of such auction (the “Auction Date”). The Trustee may engage an investment banking firm and/or other agents in connection with the Auction, the cost of which shall be included in the Minimum Auction Price (unless an Optional Termination does not occur in which case such costs shall be an expense of the Trust Fund); provided, however, that any such engagement and the choice of any such investment banking firm and/or other agents shall be subject to the consent of the Depositor.

(c)

On any Distribution Date occurring after the Initial Optional Purchase Date, the Servicer shall have the option to cause the Trust Fund to adopt a plan of complete liquidation of the Mortgage Loans pursuant to Sections 7.02 and 7.03 hereof to sell all of the property related thereto. If the Servicer elects to exercise such option, it shall no later than 30 days prior to the Distribution Date selected for purchase of the Mortgage Loans and all other assets of the Trust Fund (the “Purchase Date”) deliver written notice to the Trustee and either (a) deposit in the Distribution Account the related Redemption Price or (b) state in such notice that the 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 Servicer at a price equal to the related Redemption Price. Solely with respect to this section 7.01(c) the parties hereby agree that HomEq, in its capacity as Servicer, shall be an intended third party beneficiary

(d)

The Depositor, the Servicer, the Trustee and each Custodian shall be reimbursed from the Redemption Price for any P&I Advances, Servicer Advances, accrued and unpaid Servicing Fees or other amounts with respect to the Mortgage Loans and any related assets being purchased pursuant to Section 7.01(b) or 7.01(c) above that are reimbursable to such parties (and such other amounts which, if not related to the Mortgage Loans and other assets of the Trust Fund not being purchased, that are then due and owing to any such Person) under this Agreement and the Servicing Agreement or the related Custodial Agreement.

Section 7.02

Procedure Upon Redemption of Trust Fund.

(a)

Notice of any termination pursuant to the provisions of Section 7.01, specifying the Distribution Date upon which the final distribution shall be made or the purchase of the Trust’s assets will occur, shall be given promptly by the Trustee by first class mail to the Certificateholders mailed in the case of a redemption of the Certificates, no later than (i) the first day of the month in which the Distribution Date selected for redemption of such Certificates shall occur or (ii) upon (x) the sale of all of the property of the Trust Fund by the Trustee or in the case of a sale of assets of the Trust Fund, or (y) upon the final payment or other liquidation of the last Mortgage Loan or REO Property in the Trust Fund. Such notice shall specify (A) the Initial Optional Purchase Date, Distribution Date upon which final distribution on the Certificates of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the Certificate Registrar’s Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified. The Trustee shall give such notice to the Certificate Registrar, if not the Trustee, at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the affected Certificates shall terminate and the Trustee shall terminate the Distribution Account and any other account or fund maintained with respect to the Certificates, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(b)

In the event that all of the Holders do not surrender their Certificates for cancellation within three months after the time specified in the above-mentioned written notice, the Trustee 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 Certificates shall not have been surrendered for cancellation, the Trustee 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 Trustee shall deliver any remaining funds being held by it to the Holder of the Class R Certificates and the Holder of the Class R Certificates 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 Trustee 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 7.02. The foregoing provisions are intended to distribute to each Class of Certificates any accrued and unpaid interest and/or principal to which they are entitled based on their Pass-Through Rates and Class Certificate Balances set forth in the Preliminary Statement upon liquidation of the Trust Fund.

(c)

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

(d)

Any purchase of the Pool Assets by the Auction Purchaser shall be made on an Auction Date by receipt of the Auction Administrator of the Mortgage Loan Auction Price from the Auction Purchaser, and deposit of the Mortgage Loan Auction Price into the Distribution Account by the Auction Administrator before the Distribution Date on which such purchase is effected. Upon deposit of such purchase price into the Distribution Account, the Trustee shall, upon request and at the expense of the Auction Purchaser execute and deliver all such instruments of transfer or assignment, in each case without recourse, as shall be reasonably requested by the Auction Purchaser to vest title in the Auction Purchaser in the Pool Assets so purchased and shall transfer or deliver to the Auction Purchaser the purchased Pool Assets.

Section 7.03

Additional Trust Fund Termination Requirements.

(a)

On the termination of the Trust Fund under Section 7.01 (a), upon an Auction Sale pursuant to Section 7.01(b) or upon the exercise of the right to purchase all of the Mortgage Loans pursuant to Section 7.01(c), the Trustee shall comply with requirements of this Section 7.03 with respect to each Lower Tier REMIC relating to the assets to be sold (the “Affected REMIC”) and with respect to the Certificates corresponding to the Affected REMIC (the “Corresponding Certificates”), unless the party having the right to purchase the assets of the Affected REMIC (the “Purchaser”) delivers to the Trustee, an Opinion of Counsel (at the Servicer’s expense), addressed to the Trustee to the effect that the failure of the Trustee to comply with the requirements of this Section 7.03 will not result in an Adverse REMIC Event:

(i)

Within 89 days prior to the time of making the final payment on the Corresponding Certificates, (and upon notification by (1) the Auction Administrator in the case of a purchase under Section 7.01(b) or (2) the Servicer in the case of a purchase under Section 7.01(c)) the Trustee shall adopt on behalf of the Affected REMIC, a plan of complete liquidation, meeting the requirements of a qualified liquidation under the REMIC Provisions;

(ii)

Any sale of the assets of the Affected REMIC shall be for cash and shall occur at or after the time the plan of complete liquidation is adopted and prior to the time the final payments on the Corresponding Certificates are made;

(iii)

On the date specified for final payment of the Corresponding Certificates, the Trustee shall make final distributions of principal and interest on the Corresponding Certificates in accordance with Section 5.02 and, after payment of, or provision for any outstanding expenses, distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand after such final payment (other than cash retained to meet claims), and the portion of the Trust Fund (and the Affected REMIC) shall terminate at that time; and

(i)

In no event may the final payment on the Corresponding Certificates or the final distribution or credit to the Holders of the Residual Certificates be made after the 89th day from the date on which the plan of complete liquidation is adopted.

(b)

By its acceptance of a Residual Certificate, each Holder thereof hereby agrees to accept the plan of complete liquidation adopted by the Trustee under this Section 7.03 and to take such other action in connection therewith as may be reasonably requested by the Trustee or the Servicer.

Section 7.04

Charged-off Loans and Released Mortgage Loans.

Notwithstanding anything to the contrary contained in this Agreement, each Charged-off Loan that becomes a Released Mortgage Loan shall be released from the Trust Fund as soon as practicable after the Trustee has received notice in writing from the Servicer that a Mortgage Loan has become a Released Mortgage Loan. Upon receipt of such notice, the Trustee shall cause the related Custodian to release to the Released Mortgage Transferee the related Trustee Mortgage File and the Trustee shall execute and delivery such instruments of transfer or assignment, in each case without recourse, representation or warranty, as the Released Mortgage Transferee shall furnish to the Trustee and as shall be necessary to vest in such party the Mortgage Loan released pursuant hereto. Thereafter (i) the Released Mortgage Loan shall no longer constitute part of the Trust Fund or be an asset of any REMIC, and the Released Mortgage Transferee shall be entitled to any amounts subsequently received in respect of any such Released Mortgage Loans, (ii) the Released Mortgage Transferee may designate any servicer to service any such Released Mortgage Loan and (iii) the Released Mortgage Transferee may sell any such Released Mortgage Loan to a third party. For purposes of compliance with the REMIC Provisions, any such Released Mortgage Loan transferred to the Released Mortgage Transferee pursuant to this Section 7.04 and having any value as of the date of such transfer shall be treated as having been transferred by the related REMIC as additional compensation for services provided to such REMIC and if no such services were provided, as an additional distribution to the Class OC Certificates.

ARTICLE VIII

RIGHTS OF CERTIFICATEHOLDERS

Section 8.01

Limitation on Rights of Holders.

(a)

The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or this Trust Fund, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or take any action or proceeding in any court for a partition or winding up of this Trust Fund, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them. Except as otherwise expressly provided herein, no Certificateholder, solely by virtue of its status as a Certificateholder, shall have any right to vote or in any manner otherwise control the Trustee or the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Certificates, be construed so as to constitute the Certificateholders from time to time as partners or members of an association, nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

(b)

No Certificateholder, solely by virtue of its status as Certificateholder, shall have any right by virtue or by availing of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless the Holders of Certificates evidencing not less than 25% of the Class Principal Amount or Percentage Interest of Certificates of each Class affected thereby shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the cost, expenses and liabilities to be incurred therein or thereby, and the Trustee, for sixty days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request has been given such Trustee during such sixty-day period by such Certificateholders; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 8.01, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 8.02

Access to List of Holders.

(a)

If the Trustee is not acting as Certificate Registrar, the Certificate Registrar will furnish or cause to be furnished to the Trustee, within fifteen days after receipt by the Certificate Registrar of a request by the Trustee in writing, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Certificateholders of each Class as of the most recent Record Date.

(b)

If three or more Holders or Certificate Owners (hereinafter referred to as “Applicants”) apply in writing to the Certificate Registrar, and such application states that the Applicants desire to communicate with other Holders with respect to their rights under this Agreement or under the Certificates and is accompanied by a copy of the communication which such Applicants propose to transmit, then the Certificate Registrar shall, within five Business Days after the receipt of such application, afford such Applicants reasonable access during the normal business hours of the Certificate Registrar to the most recent list of Certificateholders held by the Certificate Registrar or shall, as an alternative, send, at the Applicants’ expense, the written communication proffered by the Applicants to all Certificateholders at their addresses as they appear in the Certificate Register.

(c)

Every Holder or Certificate Owner, if the Holder is a Clearing Agency, by receiving and holding a Certificate, agrees with the Depositor, the Certificate Registrar and the Trustee that none of the Depositor, the Certificate Registrar nor the Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 8.03

Acts of Holders of Certificates.

(a)

Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Holders or Certificate Owners, if the Holder is a Clearing Agency, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Such instrument or instruments (as the action embodies therein and evidenced thereby) are herein sometimes referred to as an “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agents shall be sufficient for any purpose of this Agreement and conclusive in favor of the Trustee, if made in the manner provided in this Section 8.03.

(b)

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments or deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Whenever such execution is by an officer of a corporation or a member of a partnership on behalf of such corporation or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the individual executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c)

The ownership of Certificates (whether or not such Certificates shall be overdue and notwithstanding any notation of ownership or other writing thereon made by anyone other than the Trustee) shall be proved by the Certificate Register, and neither the Trustee nor the Depositor shall be affected by any notice to the contrary.

(d)

Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Certificate shall bind every future Holder of the same Certificate and the Holder of every Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Trustee in reliance thereon, whether or not notation of such action is made upon such Certificate.

ARTICLE IX

REMIC ADMINISTRATION

Section 9.01

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 Trustee 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 Trustee 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 Trustee in fulfilling its duties hereunder (including its duties as tax return preparer). The Trustee shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Distribution Account, provided, however, the Trustee shall not be entitled to reimbursement for expenses incurred in connection with the preparation of tax returns and other reports as required by this Section 9.01.

(d)

The Trustee shall prepare, sign and file 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 Trustee. In preparing such returns, the Trustee shall, with respect to each REMIC other than the Master REMIC: (i) treat the accrual period for interests in such REMIC as the calendar month; (ii) account for distributions made from each REMIC other than the Master REMIC as made on the first day of each succeeding calendar month; (iii) account for income under the all-OID method at the weighted average of the Net Mortgage Rates; (iv) use the aggregation method provided in Treasury Regulation section 1.1275-2(c); and (v) account for income and expenses related to each REMIC other than the Master REMIC in the manner resulting in the lowest amount of excess inclusion income possible accruing to the Holder of the residual interest in each such REMIC.

(e)

The Trustee 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 Trustee 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 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 nor the Holder of any Residual Certificate 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 has 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 will consult with the Trustee or its designee, 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 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 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, (A) out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to holders of regular interests in any such REMIC or (B) to the extent that any such taxes are imposed on the REMIC as a result of the breach of any representation, warranty or covenant of the Trustee, then the Trustee shall pay when due any and all such taxes.

(h)

The Trustee 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)

The Trustee shall not enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)

The Class R Holder shall act as “tax matters person” with respect to each REMIC created hereunder and the Trustee shall act as agent for the Class R Holder in such roles, unless and until another party is so designated by the Class R Holder.

(l)

The Trustee shall treat the rights of the LIBOR Certificateholders to receive Basis Risk Carryforward Amounts as rights in an interest rate cap contract written by the Class OC Certificateholder in favor of such Certificateholders. Thus, each LIBOR Certificateholder shall be treated as representing not only ownership of regular interests in a REMIC, but also ownership of an interest in an interest rate cap contract. For tax purposes the interest rate cap contract will be deemed to have a value of $10,000.

Section 9.02

Prohibited Transactions and Activities.

Neither the Depositor 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).

The Trustee with respect to the Mortgage Loans shall not permit the Servicer to consent to any modification of any such Mortgage Loan for which the consent of the Trustee is required under the Servicing Agreement under which such Mortgage Loan is serviced, that would (i) increase the interest rate in respect of such Mortgage, defer for a period in excess of six months or forgive the payment of any principal or interest, reduce the outstanding principal amount (except for actual payments of principal), increase the Servicing Fee on such Mortgage Loan or extend the final maturity date on such Mortgage Loan, or (ii) result in a substitution or release of collateral or in the provision of additional collateral for the Mortgage Loan, unless the applicable Mortgage Loan is in default or default is reasonably foreseeable in respect of such Mortgage Loan, or the Trustee has received an Opinion of Counsel (at the expense of the party requesting consent for such modification) that such modification will not result in an Adverse REMIC Event.

Section 9.03

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 Trustee of its duties and obligations set forth herein, the Trustee 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 Trustee shall not be liable for any such Losses attributable to the action or inaction of the Depositor or the Holder of the Residual Certificate, nor for any such Losses resulting from misinformation provided by any of the foregoing parties on which the Trustee has relied. Notwithstanding the foregoing, however, in no event shall the Trustee 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 Agreement or Servicing Agreements or under any Acknowledgement, (2) for any Losses other than arising out of malfeasance, willful misconduct or negligent performance by the Trustee 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 9.04

REO Property.

(a)

Notwithstanding any other provision of this Agreement, the Trustee shall not, except to the extent provided in the Servicing Agreement, knowingly permit (if the permission of the Trustee is required by the Servicing Agreement) the 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 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 Servicer (to the extent provided in its Servicing Agreement) 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 Servicer (to the extent provided in its Servicing Agreement) to, dispose of any REO Property within three years of its acquisition by the Trust Fund unless the Depositor or the 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 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 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 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 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 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.

Promptly after the execution of any such amendment, the Trustee shall furnish written notification of the substance of such amendment to each Holder, the Depositor and the Rating Agencies.

(d)

It shall not be necessary for the consent of Holders under this Section 10.03 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof.

Dear Sirs:

In connection with our proposed purchase of $______________ principal amount of Xxxxxx Xxxxxxx Mortgage Loan Trust 2006-4SL, Mortgage Pass-Through Certificates (the “Privately Offered Certificates”) of Xxxxxx Xxxxxxx Capital I Inc. (the “Depositor”), we confirm that:

(1)

We understand that the Privately Offered Certificates have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be sold except as permitted in the following sentence. 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 Trust Agreement dated as of March 1, 2006 (the “Trust Agreement”), between Xxxxxx Xxxxxxx Capital I Inc., as Depositor, and LaSalle Bank National Association, as Trustee, a signed letter in the form of this letter; and we further agree, in the capacities stated above, to provide to any person purchasing any of the Privately Offered Certificates from us a notice advising such purchaser that resales of the Privately Offered Certificates are restricted as stated herein.

(2)

We understand that, in connection with any proposed resale of any Privately Offered Certificates to an Institutional Accredited Investor, we will be required to furnish to the Certificate Registrar a certification from such transferee in the form hereof to confirm that the proposed sale is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. 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 Trust Agreement.

Terms used in this letter which are not otherwise defined herein have the respective meanings assigned thereto in the Trust Agreement.

You and the Certificate Registrar are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.
