evidencing a fractional undivided interest in the distributions allocable to the Class A-[1] Certificates
with respect to a Trust Fund consisting primarily of a pool of adjustable interest rate mortgage loans
secured by first liens on one-to-four family residential properties and sold by STRUCTURED ASSET
MORTGAGE INVESTMENTS II INC.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Structured Asset Mortgage Investments II Inc. (“SAMI II”), the Master Servicer, the Securities Administrator or the Trustee referred to below or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by SAMI II, the Master Servicer or the Trustee or any of their affiliates or any other person. None of SAMI II, the Master Servicer or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

This certifies that Cede & Co. is the registered owner of the Fractional Undivided Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) primarily consisting of conventional adjustable rate mortgage loans secured by first liens on one- to four- family residential properties (collectively, the “Mortgage Loans”) sold by SAMI II. The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to SAMI II. Wells Fargo Bank, National Association (“Wells Fargo”) will act as master servicer of the Mortgage Loans (the “Master Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II, as depositor (the “Seller”), the Master Servicer, Wells Fargo, as securities administrator, EMC Mortgage Corporation and JPMorgan Chase Bank, N.A., as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Interest on this Certificate will accrue during the period from and including the preceding Distribution Date (as hereinafter defined) (or in the case of the first Distribution Date, from the Closing Date) to and including the day prior to the current Distribution Date on the Certificate Principal Balance hereof at a per annum rate equal to the Pass-Through Rate set forth above. The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the Business Day immediately preceding the related Distribution Date so long as such Certificate remains in book-entry form (and otherwise, the close of business on the last Business Day of the month immediately preceding the month of such Distribution Date), an amount equal to the product of the Fractional Undivided Interest evidenced by this Certificate and the amount (of interest and principal, if any) required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Certificate Principal Balance of this Class of Certificates will be reduced to zero.

Distributions on this Certificate will be made by the Trustee by check mailed to the address of the Person entitled thereto as such name and address shall appear on the Certificate Register or, if such Person so requests by notifying the Trustee in writing as specified in the Agreement. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Trustee for that purpose and designated in such notice. The initial Certificate Principal Balance of this Certificate is set forth above. The Certificate Principal Balance hereof will be reduced to the extent of distributions allocable to principal hereon.

This Certificate is one of a duly authorized issue of Certificates designated as set forth on the face hereof (the “Certificates”). The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the Trust Fund for payment hereunder and that neither the Securities Administrator nor the Trustee is liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

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

The Agreement permits, with certain exceptions therein provided: (i) the amendment thereof and of the Servicing Agreements and the modification of the rights and obligations of the Seller, the Master Servicer and the Trustee and the rights of the Certificateholders under the Agreement from time to time by EMC, the Seller, the Master Servicer, the Securities Administrator and the Trustee, and (ii) the amendment thereof and of the Servicing Agreements by the Master Servicer and the Trustee with the consent of the Holders of Certificates, evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund (or in certain cases, Holders of Certificates of affected Classes evidencing such percentage of the Fractional Undivided Interests thereof). Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof and of the Servicing Agreements in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable with the Trustee upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee for such purposes, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates in authorized denominations representing a like aggregate Fractional Undivided Interest will be issued to the designated transferee.

The Certificates are issuable only as registered Certificates without coupons in the Classes and denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for one or more new Certificates evidencing the same Class and in the same aggregate Fractional Undivided Interest, as requested by the Holder surrendering the same.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Seller, the Master Servicer, the Trustee, the Securities Administrator and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of Seller, the Master Servicer, the Trustee, the Securities Administrator or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby (other than the obligations to make payments to Certificateholders with respect to the termination of the Agreement) shall terminate upon the earlier of (i) the later of (A) the maturity or other liquidation (or Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the remittance of all funds due under the Agreement, or (ii) the optional repurchase by the party named in the Agreement of all the Mortgage Loans and other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only on or after the Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans is less than the percentage of the aggregate Stated Principal Balance specified in the Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

Unless this Certificate has been countersigned by an authorized signatory of the Trustee by manual signature, this Certificate shall not be entitled to any benefit under the Agreement, or be valid for any purpose.

IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.

This certifies that Bear, Stearns Securities Corp. is the registered owner of the Fractional Undivided Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) primarily consisting of conventional adjustable rate mortgage loans secured by first liens on one- to four- family residential properties (collectively, the “Mortgage Loans”) sold by SAMI II. The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to SAMI II. Wells Fargo Bank, National Association (“Wells Fargo”) will act as master servicer of the Mortgage Loans (the “Master Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II, as depositor (the “Seller”), the Master Servicer, Wells Fargo, as securities administrator, EMC Mortgage Corporation and JPMorgan Chase Bank, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month of the related Distribution Date, an amount equal to the product of the Fractional Undivided Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Current Principal Balance of this Class of Certificates will be reduced to zero.

Distributions on this Certificate will be made by the Trustee by check mailed to the address of the Person entitled thereto as such name and address shall appear on the Certificate Register or, if such Person so requests by notifying the Trustee in writing as specified in the Agreement. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Trustee for that purpose and designated in such notice. The initial Current Principal Balance of this Certificate is set forth above. The Current Principal Balance hereof will be reduced to the extent of distributions allocable to principal hereon.

No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of this Certificate is to be made without registration or qualification, the Trustee shall require receipt of (i) if such transfer is purportedly being made (a) in reliance upon Rule 144A under the 1933 Act or (b) to a transferee that is an “Institutional Accredited Investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the 1933 Act, written certifications from the Holder of the Certificate desiring to effect the transfer, and from such Holder’s prospective transferee, substantially in the forms attached to the Agreement as Exhibit F-1 or F-2, as applicable, and (ii) if requested by the Trustee, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Seller, the Trustee, the Securities Administrator or the Master Servicer in their respective capacities as such), together with copies of the written certification(s) of the Holder of the Certificate desiring to effect the transfer and/or such Holder’s prospective transferee upon which such Opinion of Counsel is based. Neither the Seller nor the Trustee is obligated to register or qualify the Class of Certificates specified on the face hereof under the 1933 Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification. Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Securities Administrator, the Seller, the Seller and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of this Class B-[3] Certificate will be made unless the Trustee and the Securities Administrator have received either (i) opinion of counsel for the benefit of the Trustee, Master Servicer and the Securities Administrator and which they may rely which is satisfactory to the Trustee that the purchase of this certificate is permissible under local law, will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and Section 4975 of the Internal Revenue Code, as amended (the “Code”) and will not subject the Master Servicer, the Trustee or the Securities Administrator to any obligation or liability in addition to those undertaken in the Agreement or (ii) a representation letter stating that the transferee is not acquiring directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement (a “Plan”) that is subject to Title I of ERISA, and/or Section 4975 of the Code, or by a person using “plan assets” of a Plan.

The Agreement permits, with certain exceptions therein provided: (i) the amendment thereof and of the Servicing Agreement and the modification of the rights and obligations of the Seller, the Master Servicer and the Trustee and the rights of the Certificateholders under the Agreement from time to time by EMC, the Seller, the Master Servicer, the Securities Administrator and the Trustee, and (ii) the amendment thereof and of the Servicing Agreement by the Master Servicer and the Trustee with the consent of the Holders of Certificates, evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund (or in certain cases, Holders of Certificates of affected Classes evidencing such percentage of the Fractional Undivided Interests thereof). Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof and of the Servicing Agreement in certain limited circumstances, without the consent of the Holders of any of the Certificates.

STATE OF	)
	)ss.:
COUNTY OF	)

[NAME OF OFFICER], being first duly sworn, deposes and says:

1. That he is [Title of Officer] of [Name of Investor] (record or beneficial owner of the Bear Stearns ALT-A Trust 2005-1, Mortgage Pass-Through Certificates, Series 2005-1, Class R-__ Certificates) (the “Class R Certificates”) (the “Owner”), a [savings institution] [corporation] duly organized and existing under the laws of [the State of _____] [the United States], on behalf of which he makes this affidavit.

2. That the Owner (i) is not and will not be as of [Closing Date][date of purchase] a “disqualified organization” within the meaning of Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Code”) or an “electing large partnership” within the meaning of Section 775 of the Code, (ii) will endeavor to remain other than a disqualified organization and an electing large partnership for so long as it retains its ownership in the Class R Certificates and (iii) is acquiring the Class R Certificates for its own account or for the account of another Owner from which it has received an affidavit and agreement in substantially the same form as this affidavit and agreement. (For this purpose, a “disqualified organization” means an electing large partnership under Section 775 of the Code, the United States, any state or political subdivision thereof, any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity) or any foreign government, international organization or any agency or instrumentality of such foreign government or organization, any rural electric or telephone cooperative, or any organization (other than certain farmers’ cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income).

3. That the Owner is aware (i) of the tax that would be imposed on transfers of Class R Certificates to disqualified organizations or electing large partnerships under the Code, that applies to all transfers of Class R Certificates after March 31, 1988; (ii) that such tax would be on the transferor (or, with respect to transfers to electing large partnerships, on each such partnership), or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a disqualified organization, on the agent; (iii) that the person (other than with respect to transfers to electing large partnerships) otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is not a disqualified organization and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that the Class R Certificates may be “noneconomic residual interests” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

4. That the Owner is aware of the tax imposed on a “pass-through entity” holding Class R Certificates if either the pass-through entity is an electing large partnership under Section 775 of the Code or if at any time during the taxable year of the pass-through entity a disqualified organization is the record holder of an interest in such entity. (For this purpose, a “pass through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.)

5. That the Owner is aware that the Trustee will not register the transfer of any Class R Certificates unless the transferee, or the transferee’s agent, delivers to it an affidavit and agreement, among other things, in substantially the same form as this affidavit and agreement. The Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false.

6. That the Owner has reviewed the restrictions set forth on the face of the Class R Certificates and the provisions of Section 5.05 of the Pooling and Servicing Agreement under which the Class R Certificates were issued. The Owner expressly agrees to be bound by and to comply with such restrictions and provisions.

7. That the Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificates will only be owned, directly or indirectly, by an Owner that is not a disqualified organization.

8. The Owner’s Taxpayer Identification Number is # _______________.

9. This affidavit and agreement relates only to the Class R Certificates held by the Owner and not to any other holder of the Class R Certificates. The Owner understands that the liabilities described herein relate only to the Class R Certificates.

10. That no purpose of the Owner relating to the transfer of any of the Class R Certificates by the Owner is or will be to impede the assessment or collection of any tax; in making this representation, the Owner warrants that the Owner is familiar with (i) Treasury Regulation Section 1.860E-1 (c) and recent amendments thereto, effective as of August 19, 2002, and (ii) the preamble describing the adoption of the amendments to such regulation, which is attached hereto as Exhibit 1.

11. That the Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Certificates remain outstanding. In this regard, the Owner hereby represents to and for the benefit of the person from whom it acquired the Class R Certificates that the Owner intends to pay taxes associated with holding such Class R Certificates as they become due, fully understanding that it may incur tax liabilities in excess of any cash flows generated by the Class R Certificates.

12. That the Owner has no present knowledge or expectation that it will become insolvent or subject to a bankruptcy proceeding for so long as any of the Class R Certificates remain outstanding.

13. The Owner is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in, or under the laws of, the United States or any political subdivision thereof, or an estate or trust whose income from sources without the United States is includable in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States.

14. The Owner hereby agrees that it will not cause income from the Class R Certificates to be attributable to a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Owner or another United States taxpayer.

15. (a) The Purchaser hereby certifies, represents and warrants to, and covenants with the Company, the Trustee and the Master Servicer that the following statements in (1) or (2) are accurate:

(2) The purchase of Certificates is permissible under applicable law, will not constitute or result in any prohibited transaction under ERISA or Section 4975 of the Code, will not subject the Company, the Trustee or the Master Servicer to any obligation in addition to those undertaken in the Pooling and Servicing Agreement and, with respect to each source of funds (“Source”) being used by the Purchaser to acquire the Certificates, each of the following statements is accurate: (a) the Purchaser is an insurance company; (b) the Source is assets of the Purchaser’s “general account;” (c) the conditions set forth in Prohibited Transaction Class Exemption (“PTCE”) 95-60 issued by the DOL have been satisfied and the purchase, holding and transfer of Certificates by or on behalf of the Purchaser are exempt under PTCE 95-60; and (d) the amount of reserves and liabilities for such general account contracts held by or on behalf of any Plan does not exceed 10% of the total reserves and liabilities of such general account plus surplus as of the date hereof (for purposes of this clause, all Plans maintained by the same employer (or affiliate thereof) or employee organization are deemed to be a single Plan) in connection with its purchase and holding of such Certificates; or

(b) The Owner will provide the Trustee, the Company and the Master Servicer with an opinion of counsel acceptable to and in form and substance satisfactory to the Trustee, the Company and the Master Servicer to the effect that the purchase of Certificates is permissible under applicable law, will not constitute or result in any non-exempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Trustee, the Company or the Master Servicer to any obligation or liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in the Pooling and Servicing Agreement.

In addition, the Owner hereby certifies, represents and warrants to, and covenants with, the Company, the Trustee and the Master Servicer that the Owner will not transfer such Certificates to any Plan or person unless either such Plan or person meets the requirements set forth in either (a) or (b) above.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter set forth, the Trustee, the Company, the Master Servicer and the Custodian hereby agree as follows:

ARTICLE I
DEFINITIONS

Capitalized terms used in this Agreement and not defined herein shall have the meanings assigned in the Original Pooling and Servicing Agreement, unless otherwise required by the context herein.

ARTICLE II
CUSTODY OF MORTGAGE DOCUMENTS

Section 2.1 Custodian to Act as Agent: Acceptance of Mortgage Files. The Custodian, as the duly appointed agent of the Trustee for these purposes, acknowledges (subject to any exceptions noted in the Initial Certification referred to in Section 2.3(a) receipt of the Mortgage Files relating to the Mortgage Loans identified on the schedule attached hereto (the “Mortgage Files”) and declares that it holds and will hold such Mortgage Files as agent for the Trustee, in trust, for the use and benefit of all present and future Certificateholders.

Section 2.2 Recordation of Assignments. If any Mortgage File includes one or more assignments of Mortgage to the Trustee in a state which is specifically excluded from the Opinion of Counsel delivered by the Seller to the Trustee (with a copy to the Custodian) pursuant to the provisions of Section 2.01 of the Pooling and Servicing Agreement, each such assignment shall be delivered by the Custodian to the Company for the purpose of recording it in the appropriate public office for real property records, and the Company, at no expense to the Custodian, shall promptly cause to be recorded in the appropriate public office for real property records each such assignment of Mortgage and, upon receipt thereof from such public office, shall return each such assignment of Mortgage to the Custodian.

Section 2.3 Review of Mortgage Files.

(1) On or prior to the Closing Date, in accordance with Section 2.02 of the Pooling and Servicing Agreement, the Custodian shall deliver to the Trustee an Initial Certification in the form annexed hereto as Exhibit One evidencing receipt (subject to any exceptions noted therein) of a Mortgage File for each of the Mortgage Loans listed on the Schedule attached hereto (the “Mortgage Loan Schedule”).

(2) Within 90 days of the Closing Date, the Custodian agrees, for the benefit of Certificateholders, to review, in accordance with the provisions of Section 2.02 of the Pooling and Servicing Agreement, each such document, and shall deliver to the Seller and the Trustee an Interim Certification in the form annexed hereto as Exhibit Two to the effect that all such documents have been executed and received and that such documents relate to the Mortgage Loans identified on the Mortgage Loan Schedule, except for any exceptions listed on Schedule A attached to such Interim Certification. The Custodian shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

(3) Not later than 180 days after the Closing Date, the Custodian shall review the Mortgage Files as provided in Section 2.02 of the Pooling and Servicing Agreement and deliver to the Seller and the Trustee a Final Certification in the form annexed hereto as Exhibit Three evidencing the completeness of the Mortgage Files.

(4) In reviewing the Mortgage Files as provided herein and in the Pooling and Servicing Agreement, the Custodian shall make no representation as to and shall not be responsible to verify (i) the validity, legality, enforceability, due authorization, recordability, sufficiency or genuineness of any of the documents included in any Mortgage File or (ii) the collectibility, insurability, effectiveness or suitability of any of the documents in any Mortgage File.

Upon receipt of written request from the Trustee, the Custodian shall as soon as practicable supply the Trustee with a list of all of the documents relating to the Mortgage Loans missing from the Mortgage Files.

Section 2.4 Notification of Breaches of Representations and Warranties. Upon discovery by the Custodian of a breach of any representation or warranty made by the Company as set forth in the Pooling and Servicing Agreement with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall give prompt written notice to the Company, the related Servicer and the Trustee.

Section 2.5 Custodian to Cooperate: Release of Mortgage Files. Upon receipt of written notice from the Trustee that the Mortgage Loan Seller has repurchased a Mortgage Loan pursuant to Article II of the Pooling and Servicing Agreement, and that the purchase price therefore has been deposited in the Master Servicer Collection Account or the Distribution Account, then the Custodian agrees to promptly release to the Mortgage Loan Seller the related Mortgage File.

Upon the Custodian’s receipt of a request for release (a “Request for Release”) substantially in the form of Exhibit D to the Pooling and Servicing Agreement signed by a Servicing Officer of the related Servicer stating that it has received payment in full of a Mortgage Loan or that payment in full will be escrowed in a manner customary for such purposes, the Custodian agrees promptly to release to the related Servicer the related Mortgage File. The Company shall deliver to the Custodian and the Custodian agrees to accept the Mortgage Note and other documents constituting the Mortgage File with respect to any Substitute Mortgage Loan.

From time to time as is appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Primary Insurance Policy, the related Servicer shall deliver to the Custodian a Request for Release signed by a Servicing Officer requesting that possession of all of the Mortgage File be released to the related Servicer and certifying as to the reason for such release and that such release will not invalidate any insurance coverage provided in respect of the Mortgage Loan under any of the Insurance Policies. Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File to the related Servicer. The related Servicer shall cause each Mortgage File or any document therein so released to be returned to the Custodian when the need therefore by the related Servicer no longer exists, unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Master Servicer Collection Account or the Distribution Account or (ii) the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the related Servicer has delivered to the Custodian a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery.

At any time that a Servicer is required to deliver to the Custodian a Request for Release, the Servicer shall deliver two copies of the Request for Release if delivered in hard copy or the Servicer may furnish such Request for Release electronically to the Custodian, in which event the Servicing Officer transmitting the same shall be deemed to have signed the Request for Release. In connection with any Request for Release of a Mortgage File because of a repurchase of a Mortgage Loan, such Request for Release shall be accompanied by an assignment of mortgage, without recourse, representation or warranty from the Trustee to the Mortgage Loan Seller and the related Mortgage Note shall be endorsed without recourse, representation or warranty by the Trustee and be returned to the Mortgage Loan Seller. In connection with any Request for Release of a Mortgage File because of the payment in full of a Mortgage Loan, such Request for Release shall be accompanied by a certificate of satisfaction or other similar instrument to be executed by or on behalf of the Trustee and returned to the related Servicer.

Section 2.6 Assumption Agreements. In the event that any assumption agreement, substitution of liability agreement or sale of servicing agreement is entered into with respect to any Mortgage Loan subject to this Agreement in accordance with the terms and provisions of the Pooling and Servicing Agreement, the Master Servicer, to the extent provided in the related Servicing Agreement, shall cause the related Servicer to notify the Custodian that such assumption or substitution agreement has been completed by forwarding to the Custodian the original of such assumption or substitution agreement, which shall be added to the related Mortgage File and, for all purposes, shall be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting parts thereof.

ARTICLE III

With respect to each Mortgage Note, Mortgage and other documents constituting each Mortgage File which are delivered to the Custodian, the Custodian is exclusively the bailee and agent of the Trustee and has no instructions to hold any Mortgage Note or Mortgage for the benefit of any person other than the Trustee and the Certificateholders and undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. Except upon compliance with the provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or Mortgage File shall be delivered by the Custodian to the Company, the Servicers or the Master Servicer or otherwise released from the possession of the Custodian.

Section 3.5 Custodian May Resign Trustee May Remove Custodian. The Custodian may resign from the obligations and duties hereby imposed upon it as such obligations and duties relate to its acting as Custodian of the Mortgage Loans. Upon receiving such notice of resignation, the Trustee shall either take custody of the Mortgage Files itself and give prompt notice thereof to the Company, the Master Servicer and the Custodian, or promptly appoint a successor Custodian by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Custodian and one copy to the successor Custodian. If the Trustee shall not have taken custody of the Mortgage Files and no successor Custodian shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Custodian may petition any court of competent jurisdiction for the appointment of a successor Custodian.

The Trustee may remove the Custodian at any time with the consent of the Master Servicer. In such event, the Trustee shall appoint, or petition a court of competent jurisdiction to appoint, a successor Custodian hereunder. Any successor Custodian shall be a depository institution subject to supervision or examination by federal or state authority, shall be able to satisfy the other requirements contained in Section 3.7 and shall be unaffiliated with the Servicer or the Company.

Any resignation or removal of the Custodian and appointment of a successor Custodian pursuant to any of the provisions of this Section 3.5 shall become effective upon acceptance of appointment by the successor Custodian. The Trustee shall give prompt notice to the Company and the Master Servicer of the appointment of any successor Custodian. No successor Custodian shall be appointed by the Trustee without the prior approval of the Company and the Master Servicer.

Section 3.6 Merger or Consolidation of Custodian. Any Person into which the Custodian may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Custodian shall be a party, or any Person succeeding to the business of the Custodian, shall be the successor of the Custodian hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 3.7 Representations of the Custodian. The Custodian hereby represents that it is a depository institution subject to supervision or examination by a federal or state authority, has a combined capital and surplus of at least $15,000,000 and is qualified to do business in the jurisdictions in which it will hold any Mortgage File.

The Mortgage Loan Seller will be entitled to all scheduled payments of principal and interest on the Mortgage Loans due on or before the Cut-off Date (including payments collected after the Cut-off Date) and all payments thereon, other than scheduled principal and interest, received on or before the Cut-off Date. Such principal amounts and any interest thereon belonging to the Mortgage Loan Seller as described above will not be included in the aggregate outstanding principal balance of the Mortgage Loans as of the Cut-off Date as set forth on the Final Mortgage Loan Schedule.

(ii) Pursuant to various conveyance documents to be executed on the Closing Date and pursuant to the Pooling and Servicing Agreement, the Purchaser will assign on the Closing Date all of its right, title and interest in and to the Mortgage Loans to the Trustee for the benefit of the Certificateholders. In connection with the transfer and assignment of the Mortgage Loans, the Mortgage Loan Seller has delivered or will deliver or cause to be delivered to the Trustee by the Closing Date or such later date as is agreed to by the Purchaser and the Mortgage Loan Seller (each of the Closing Date and such later date is referred to as a “Mortgage File Delivery Date”), the items of each Mortgage File, provided, however, that in lieu of the foregoing, the Mortgage Loan Seller may deliver the following documents, under the circumstances set forth below: (x) in lieu of the original Security Instrument, assignments to the Trustee or intervening assignments thereof which have been delivered, are being delivered or will, upon receipt of recording information relating to the Security Instrument required to be included thereon, be delivered to recording offices for recording and have not been returned to the Mortgage Loan Seller in time to permit their delivery as specified above, the Mortgage Loan Seller may deliver a true copy thereof with a certification by the Mortgage Loan Seller, on the face of such copy, substantially as follows: “Certified to be a true and correct copy of the original, which has been transmitted for recording” (y) in lieu of the Security Instrument, assignments to the Trustee or intervening assignments thereof, if the applicable jurisdiction retains the originals of such documents (as evidenced by a certification from the Mortgage Loan Seller to such effect) the Mortgage Loan Seller may deliver photocopies of such documents containing an original certification by the judicial or other governmental authority of the jurisdiction where such documents were recorded; and (z) in lieu of the Mortgage Notes relating to the Mortgage Loans, each identified in the list delivered by the Purchaser to the Trustee on the Closing Date and attached hereto as Exhibit 5, the Mortgage Loan Seller may deliver lost note affidavits and indemnities of the Mortgage Loan Seller; and provided further, however, that in the case of Mortgage Loans which have been prepaid in full after the Cut-off Date and prior to the Closing Date, the Mortgage Loan Seller, in lieu of delivering the above documents, may deliver to the Trustee a certification by the Mortgage Loan Seller or the Master Servicer to such effect. The Mortgage Loan Seller shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) or such certified copies to the Trustee promptly after they are received. The Mortgage Loan Seller shall cause the Mortgage and intervening assignments, if any, and the assignment of the Security Instrument to be recorded not later than 180 days after the Closing Date, unless such assignment is not required to be recorded under the terms set forth in Section 6(i) hereof.

(iii) The Mortgage Loan Seller and the Purchaser acknowledge hereunder that all of the Mortgage Loans and the related servicing will ultimately be assigned to JPMorgan Chase Bank, N.A., as Trustee for the Certificateholders, on the date hereof.

SECTION 5. Examination of Mortgage Files.

(i) On or before the Mortgage File Delivery Date, the Mortgage Loan Seller will have made the Mortgage Files available to the Purchaser or its agent for examination which may be at the offices of the Trustee or the Mortgage Loan Seller and/or the Mortgage Loan Seller’s custodian. The fact that the Purchaser or its agent has conducted or has failed to conduct any partial or complete examination of the Mortgage Files shall not affect the Purchaser’s rights to demand cure, repurchase, substitution or other relief as provided in this Agreement. In furtherance of the foregoing, the Mortgage Loan Seller shall make the Mortgage Files available to the Purchaser or its agent from time to time so as to permit the Purchaser to confirm the Mortgage Loan Seller’s compliance with the delivery and recordation requirements of this Agreement and the Pooling and Servicing Agreement. In addition, upon request of the Purchaser, the Mortgage Loan Seller agrees to provide to the Purchaser, Bear Stearns and to any investors or prospective investors in the Certificates information regarding the Mortgage Loans and their servicing, to make the Mortgage Files available to the Purchaser, Bear Stearns and to such investors or prospective investors (which may be at the offices of the Mortgage Loan Seller and/or the Mortgage Loan Seller’s custodian) and to make available personnel knowledgeable about the Mortgage Loans for discussions with the Purchaser, Bear Stearns and such investors or prospective investors, upon reasonable request during regular business hours, sufficient to permit the Purchaser, Bear Stearns and such investors or potential investors to conduct such due diligence as any such party reasonably believes is appropriate.

(ii) Pursuant to the Pooling and Servicing Agreement, on the Closing Date the Trustee, for the benefit of the Certificateholders, will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver or cause the Custodian to deliver to the Mortgage Loan Seller an initial certification in the form attached as Exhibit One to the Custodial Agreement.

(iii) Pursuant to the Pooling and Servicing Agreement, within 90 days of the Closing Date, the Trustee will review or shall cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver to the Mortgage Loan Seller and the Master Servicer an interim certification substantially in the form of Exhibit Two to the Custodial Agreement.

(iv) Pursuant to the Pooling and Servicing Agreement, within 180 days of the Closing Date (or, with respect to any Substitute Mortgage Loan, within five Business Days after the receipt by the Trustee or Custodian thereof) the Trustee will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver to the Mortgage Loan Seller and the Master Servicer a final certification substantially in the form of Exhibit Three to the Custodial Agreement. If the Trustee is unable to deliver a final certification with respect to the items listed in Exhibit 1 due to any document that is missing, has not been executed, is unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in the Final Mortgage Loan Schedule (a “Material Defect”), the Trustee or the Custodian, as its agent, shall promptly notify the Mortgage Loan Seller of such Material Defect. The Mortgage Loan Seller shall correct or cure any such Material Defect within 90 days from the date of notice from the Trustee or the Custodian, as its agent, of the Material Defect and if the Mortgage Loan Seller does not correct or cure such Material Defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Mortgage Loan Seller will, in accordance with the terms of the Pooling and Servicing Agreement, within 90 days of the date of notice, provide the Trustee with a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase the related Mortgage Loan at the applicable Purchase Price; provided that, if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3) of the Code, any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered; provided, however, that if such defect relates solely to the inability of the Mortgage Loan Seller to deliver the original security instrument or intervening assignments thereof, or a certified copy because the originals of such documents, or a certified copy, have not been returned by the applicable jurisdiction, the Mortgage Loan Seller shall not be required to purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date. The foregoing repurchase obligation shall not apply in the event that the Mortgage Loan Seller cannot deliver such original or copy of any document submitted for recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Mortgage Loan Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate of Mortgage Loan Seller or a Servicing Officer confirming that such documents have been accepted for recording, and delivery to the Trustee or the Custodian, as its agent, shall be effected by the Mortgage Loan Seller within thirty days of its receipt of the original recorded document.

(v) At the time of any substitution, the Mortgage Loan Seller shall deliver or cause to be delivered the Substitute Mortgage Loan, the related Mortgage File and any other documents and payments required to be delivered in connection with a substitution pursuant to the Pooling and Servicing Agreement. At the time of any purchase or substitution, the Trustee shall (i) assign to the Mortgage Loan Seller and release or cause the Custodian to release the documents (including, but not limited to, the Mortgage, Mortgage Note and other contents of the Mortgage File) in its possession or in the possession of the Custodian relating to the Deleted Mortgage Loan and (ii) execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Mortgage Loan Seller title to such Deleted Mortgage Loan.

SECTION 6. Recordation of Assignments of Mortgage.

(i) The Mortgage Loan Seller shall, promptly after the Closing Date, cause each Mortgage and each assignment of Mortgage from the Mortgage Loan Seller to the Trustee, and all unrecorded intervening assignments, if any, delivered on or prior to the Closing Date, to be recorded in all recording offices in the jurisdictions where the related Mortgaged Properties are located; provided, however, the Mortgage Loan Seller need not cause to be recorded any assignment which relates to a Mortgage Loan if (a) such recordation is not required by the Rating Agencies or an Opinion of Counsel has been provided to the Trustee which states that the recordation of such assignment is not necessary to protect the Trustee’s interest in the related Mortgage Loan or (b) MERS is identified on the Mortgage or a properly recorded assignment of the Mortgage, as the Mortgagee of record solely as nominee for the Mortgage Loan Seller and its successors and assigns; provided, however, notwithstanding the delivery of any Opinion of Counsel, each assignment of Mortgage shall be submitted for recording by the Mortgage Loan Seller in the manner described above, at no expense to the Trust Fund or Trustee, upon the earliest to occur of (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgage Loan Seller and (iv) the occurrence of a servicing transfer as described in Section 8.02 of the Pooling and Servicing Agreement.

While each such Mortgage or assignment is being recorded, if necessary, the Mortgage Loan Seller shall leave or cause to be left with the Trustee a certified copy of such Mortgage or assignment. In the event that, within 180 days of the Closing Date, the Trustee has not been provided an Opinion of Counsel as described above or received evidence of recording with respect to each Mortgage Loan delivered to the Purchaser pursuant to the terms hereof or as set forth above, the failure to provide evidence of recording or such Opinion of Counsel (in the alternative, if required) shall be considered a Material Defect, and the provisions of Section 5(iii) and (iv) shall apply. All customary recording fees and reasonable expenses relating to the recordation of the assignments of mortgage to the Trustee or the Opinion of Counsel, as the case may be, shall be borne by the Mortgage Loan Seller.

(ii) It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser, as contemplated by this Agreement be, and be treated as, a sale. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser to secure a debt or other obligation of the Mortgage Loan Seller. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans are held by a court to continue to be property of the Mortgage Loan Seller, then (a) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 9 of the applicable Uniform Commercial Code; (b) the transfer of the Mortgage Loans provided for herein shall be deemed to be a grant by the Mortgage Loan Seller to the Purchaser of a security interest in all of the Mortgage Loan Seller’s right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, to the extent the Purchaser would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to Section 4 hereof, including all amounts, other than investment earnings, from time to time held or invested in any accounts created pursuant to the Pooling and Servicing Agreement, whether in the form of cash, instruments, securities or other property; (c) the possession by the Purchaser or the Trustee of Mortgage Notes and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “possession by the secured party” for purposes of perfecting the security interest pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code; and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to any provision hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed to be an assignment of any security interest created hereby. The Mortgage Loan Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Pooling and Servicing Agreement.

In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent it may elect by written notice delivered to the indemnified party promptly (but, in any event, within 30 days) after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party.

Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement or any claim or action effected without its written consent; provided, however, that such consent was not unreasonably withheld.

(iv) If the indemnification provided for in paragraphs (i) and (ii) of this Section 13 shall for any reason be unavailable to an indemnified party in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to in Section 13, then the indemnifying party shall in lieu of indemnifying the indemnified party contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative benefits received by the Mortgage Loan Seller on the one hand and the Purchaser on the other from the purchase and sale of the Mortgage Loans, the offering of the Certificates and the other transactions contemplated hereunder. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for such fraudulent misrepresentation.

(v) The parties hereto agree that reliance by an indemnified party on any publicly available information or any information or directions furnished by an indemnifying party shall not constitute negligence, bad faith or willful misconduct by such indemnified party.

SECTION 14. Notices. All demands, notices and communications hereunder shall be in writing but may be delivered by facsimile transmission subsequently confirmed in writing. Notices to the Mortgage Loan Seller shall be directed to EMC Mortgage Corporation, Mac Arthur Ridge II, 909 Hidden Ridge Drive, Suite 200, Irving, Texas 75038 (Telecopy: (972-444-2880)), and notices to the Purchaser shall be directed to Structured Asset Mortgage Investments II Inc., 383 Madison Avenue, New York, New York 10179 (Telecopy: (212-272-7206)), Attention: Baron Silverstein; or to any other address as may hereafter be furnished by one party to the other party by like notice.

SECTION 16. Termination. This Agreement may be terminated (a) by the mutual consent of the parties hereto prior to the Closing Date, (b) by the Purchaser, if the conditions to the Purchaser’s obligation to close set forth under Section 10(1) hereof are not fulfilled as and when required to be fulfilled or (c) by the Mortgage Loan Seller, if the conditions to the Mortgage Loan Seller’s obligation to close set forth under Section 10(2) hereof are not fulfilled as and when required to be fulfilled. In the event of termination pursuant to clause (b), the Mortgage Loan Seller shall pay, and in the event of termination pursuant to clause (c), the Purchaser shall pay, all reasonable out-of-pocket expenses incurred by the other in connection with the transactions contemplated by this Agreement. In the event of a termination pursuant to clause (a), each party shall be responsible for its own expenses.

SECTION 17. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Mortgage Loan Seller submitted pursuant hereto, shall remain operative and in full force and effect and shall survive delivery of the Mortgage Loans to the Purchaser (and by the Purchaser to the Trustee). Subsequent to the delivery of the Mortgage Loans to the Purchaser, the Mortgage Loan Seller’s representations and warranties contained herein with respect to the Mortgage Loans shall be deemed to relate to the Mortgage Loans actually delivered to the Purchaser and included in the Final Mortgage Loan Schedule and any Substitute Mortgage Loan and not to those Mortgage Loans deleted from the Preliminary Mortgage Loan Schedule pursuant to Section 3 hereof prior to the Closing or any Deleted Mortgage Loan.

SECTION 18. Severability. If any provision of this Agreement shall be prohibited or invalid under applicable law, the Agreement shall be ineffective only to such extent, without invalidating the remainder of this Agreement.

APPENDIX E – Standard & Poor’s Anti-Predatory Lending Categorization

Standard & Poor’s has categorized loans governed by anti-predatory lending laws in the Jurisdictions listed below into three categories based upon a combination of factors that include (a) the risk exposure associated with the assignee liability and (b) the tests and thresholds set forth in those laws. Note that certain loans classified by the relevant statute as Covered are included in Standard & Poor’s High Cost Loan Category because they included thresholds and tests that are typical of what is generally considered High Cost by the industry.
