Section 2.03. Purposes and Powers. The purpose of the Trust is to engage in the following activities:

(i) to issue the Notes pursuant to the Indenture and the Certificates pursuant to this Trust Agreement and to sell the Notes and the Certificates;

(ii) to pay the organizational, start-up and transactional expenses of the Trust;

(iii) to assign, grant, transfer, pledge and convey the Mortgage Loans pursuant to the Indenture and to hold, manage and distribute to the Certificateholder pursuant to Section 5.01 herein, any portion of the Mortgage Loans released from the Lien of, and remitted to the Trust pursuant to the Indenture;

(iv) to enter into and perform its obligations under the Basic Documents to which it is to be a party;

(v) if directed by holders of Certificates representing more than 50% of the beneficial interests in the Trust, sell the Trust Estate subsequent to the discharge of the Indenture, all for the benefit of the holders of the Certificates;

(vi) to engage in those activities, including entering into agreements, that are necessary, suitable or convenient to accomplish the foregoing or are incidental thereto or connected therewith; and

(vii) subject to compliance with the Basic Documents, to engage in such other activities as may be required in connection with conservation of the Owner Trust Estate and the making of distributions to the Certificateholder and the Noteholders.

The Trust is hereby authorized to engage in the foregoing activities. The Trust shall not engage in any activity other than in connection with the foregoing or other than as required or authorized by the terms of this Trust Agreement or the Basic Documents.

Section 2.04. Appointment of Owner Trustee. The Depositor hereby appoints the Owner Trustee as trustee of the Trust effective as of the date hereof, to have all the rights, powers and duties set forth herein.

Section 2.05. Initial Capital Contribution of Owner Trust Estate. The Depositor hereby sells, assigns, transfers, conveys and sets over to the Trust, as of the date hereof, the sum of $1. The Owner Trustee hereby acknowledges receipt in trust from the Depositor, as of the date hereof, of the foregoing contribution, which shall constitute the initial corpus of the Trust and shall be deposited in the Certificate Distribution Account. The Owner Trustee also acknowledges on behalf of the Trust the receipt in trust of the Mortgage Loans and the rights with respect to the representations and warranties made by the Seller under the Mortgage Loan Purchase Agreement which shall constitute the Owner Trust Estate.

Section 2.06. Declaration of Trust. The Owner Trustee hereby declares that it shall hold the Owner Trust Estate in trust upon and subject to the conditions set forth herein for the use and benefit of the Certificateholders, subject to the obligations of the Trust under the Basic Documents. It is the intention of the parties hereto that the Trust constitute a “statutory trust” under the Statutory Trust Statute and that this Trust Agreement constitute the governing instrument of such statutory trust. It is the intention of the parties hereto that, for federal and state income and state and local franchise tax purposes, (A) the Trust shall not be treated as (i) an association subject separately to taxation as a corporation, (ii) a “publicly traded partnership” as defined in Treasury Regulation Section 1.7704-1 or (iii) a “taxable mortgage pool” as defined in Section 7701(i) of the Code, (B) the Trust shall, as of the Closing Date, be disregarded as a separate entity (and if at any other time the Trust Certificates are held by more than one person for federal income tax purposes, shall be treated as a partnership), and (C) each Class of Notes shall be debt, and the provisions of this Agreement shall be interpreted to further this intention. Except as otherwise provided in this Trust Agreement, the rights of the Certificateholders will be those of equity owners of the Trust. Effective as of the date hereof, the Owner Trustee shall have all rights, powers and duties set forth herein and in the Statutory Trust Statute with respect to accomplishing the purposes of the Trust.

Section 2.07. Liability of the Holders of the Certificates. The Holders of the Certificates shall be jointly and severally liable directly to and shall indemnify any injured party for all losses, claims, damages, liabilities and expenses of the Trust and the Owner Trustee (including Expenses, to the extent not paid out of the Owner Trust Estate) to the extent that the Holders of the Certificates would be liable if the Trust were a corporation, and the Holders of the Certificates were common stockholders in the corporation, under Delaware corporate law; provided, however, that the Holders of the Certificates shall not be liable for payments required to be made on the Notes or the Certificates, or for any losses incurred by a Certificateholder in the capacity of an investor in the Certificates or a Noteholder in the capacity of an investor in the Notes. The Holders of the Certificates shall be liable for and shall promptly pay any entity level taxes imposed on the Trust. In addition, any third party creditors of the Trust (other than in connection with the obligations described in the second preceding sentence for which the Holders of the Certificates shall not be liable) shall be deemed third party beneficiaries of this paragraph. The obligations of the Holders of the Certificates under this paragraph shall be evidenced by the Certificates.

Section 2.08. Title to Trust Property. Except with respect to the Mortgage Loans, which will be assigned of record to the Indenture Trustee pursuant to the Indenture, legal title to the Owner Trust Estate shall be vested at all times in the Trust as a separate legal entity except where applicable law in any jurisdiction requires title to any part of the Owner Trust Estate to be vested in a trustee or trustees, in which case title shall be deemed to be vested in the Owner Trustee, a co-trustee and/or a separate trustee, as the case may be.

Section 2.09. Situs of Trust. The Trust will be located and administered in the State of Delaware. All bank accounts maintained by the Owner Trustee on behalf of the Trust shall be located in the State of Delaware. The Trust shall not have any employees in any state other than Delaware; provided, however, that nothing herein shall restrict or prohibit the Owner Trustee from having employees within or without the State of Delaware or taking actions outside the State of Delaware in order to comply with Section 2.03. Payments will be received by the Trust only in Delaware, Maryland, Minnesota or New York, and payments will be made by the Trust only from Delaware, Maryland, Minnesota or New York. The only office of the Trust maintained by the Owner Trustee will be at the Corporate Trust Office in Delaware or California.

Section 2.10. Representations and Warranties of the Depositor. The Depositor hereby represents and warrants to the Owner Trustee that:

(i) The Depositor is duly organized and validly existing as a corporation in good standing under the laws of the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are currently owned and such business is presently conducted.

(ii) The Depositor is duly qualified to do business as a foreign corporation in good standing and has obtained all necessary licenses and approvals in all jurisdictions in which the ownership or lease of its property or the conduct of its business shall require such qualifications and in which the failure to so qualify would have a material adverse effect on the business, properties, assets or condition (financial or other) of the Depositor.

(iii) The Depositor has the power and authority to execute and deliver this Trust Agreement and to carry out its terms; the Depositor has full power and authority to convey and assign the property to be conveyed and assigned to and deposited with the Trust as part of the Owner Trust Estate and the Depositor has duly authorized such conveyance and assignment and deposit to the Trust by all necessary corporate action; and the execution, delivery and performance of this Trust Agreement have been duly authorized by the Depositor by all necessary corporate action.

(iv) The consummation of the transactions contemplated by this Trust Agreement and the fulfillment of the terms hereof do not conflict with, result in any breach of any of the terms and provisions of, or constitute (with or without notice or lapse of time) a default under, the articles of incorporation or bylaws of the Depositor, or any indenture, agreement or other instrument to which the Depositor is a party or by which it is bound; nor result in the creation or imposition of any Lien upon any of its properties pursuant to the terms of any such indenture, agreement or other instrument (other than pursuant to the Basic Documents); nor violate any law or, to the best of the Depositor's

knowledge, any order, rule or regulation applicable to the Depositor of any court or of any federal or state regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or its properties.

(v) The Trust is not required to register as an investment company under the Investment Company Act and is not under the control of a Person required to so register.

Section 2.11. Investment Company. Neither the Depositor nor any holder of a Certificate shall take any action which would cause the Trust to become an “investment company” which would be required to register under the Investment Company Act.

ARTICLE III

Conveyance of the Mortgage Loans;

Certificates

Section 3.01. Initial Ownership. Upon the formation of the Trust by the contribution by the Depositor pursuant to Section 2.01 and until the conveyance of the Mortgage Loans pursuant to Section 2.01 of the Sale and Servicing Agreement and the issuance of the Certificates, and thereafter except as otherwise permitted hereunder, the Depositor shall be the sole Certificateholder.

Section 3.02. The Certificates. The Certificates shall be issued in the form of one or more Certificates, each representing not less than a 10% Certificate Percentage Interest. The Certificates shall be executed on behalf of the Trust by manual or facsimile signature of an authorized officer of the Owner Trustee and authenticated in the manner provided in Section 3.03. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to the benefit of this Trust Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of authentication and delivery of such Certificates. A Person shall become a Certificateholder and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such Person's acceptance of a Certificate duly registered in such Person's name, pursuant to Section 3.04.

A transferee of a Certificate shall become a Certificateholder and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such transferee's acceptance of a Certificate duly registered in such transferee's name pursuant to and upon satisfaction of the conditions set forth in Section 3.04.

Section 3.03. Authentication of Certificates. The Owner Trustee shall cause all Certificates issued hereunder to be executed and authenticated on behalf of the Trust, authenticated and delivered to or upon the written order of the Depositor, signed by its chairman of the board, its president or any vice president, without further corporate action by the Depositor, in authorized denominations. No Certificate shall entitle its holder to any benefit under this Trust Agreement or be valid for any purpose unless there shall appear on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A, executed by the Owner Trustee or the Certificate Registrar by manual signature; such authentication shall constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

Section 3.04. Registration of and Limitations on Transfer and Exchange of Certificates. The Certificate Registrar shall keep or cause to be kept, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. If the Certificate Registrar resigns or is removed, the Owner Trustee shall appoint a successor Certificate Registrar.

Subject to satisfaction of the conditions set forth below with respect to the Certificate, upon surrender for registration of transfer of any Certificate at the office or agency maintained pursuant to Section 3.08, the Owner Trustee or the Certificate Registrar shall execute, authenticate and deliver in the name of the designated transferee or transferees, one or more new Certificates in authorized denominations of a like aggregate amount dated the date of authentication by the Owner Trustee or the Certificate Registrar. At the option of a Holder, Certificates may be exchanged for other Certificates of authorized denominations of a like aggregate amount upon surrender of the Certificates to be exchanged at the office or agency maintained pursuant to Section 3.08.

Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder or such Holder's attorney duly authorized in writing. Each Certificate surrendered for registration of transfer or exchange shall be cancelled and subsequently disposed of by the Certificate Registrar in accordance with its customary practice.

No service charge shall be made for any registration of transfer or exchange of Certificates, but the Owner Trustee or 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 transfer or exchange of Certificates.

No Person shall become a Certificateholder until it shall establish its non-foreign status by submitting to the Certificate Paying Agent an IRS Form W-9 and the Certificate of Non-Foreign Status set forth in Exhibit D hereto.

No transfer, sale, pledge or other disposition of a Certificate shall be made unless such transfer, sale, pledge or other disposition is exempt from the registration requirements of the Securities Act and any applicable state securities laws or is made in accordance with said Act and laws. In the event of any such transfer, the Certificate Registrar or the Depositor shall prior to such transfer require the transferee to execute (A) either (i) an investment letter in substantially the form attached hereto as Exhibit C (or in such form and substance reasonably satisfactory to the Certificate Registrar and the Depositor) which investment letter shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar, the Master Servicer, the Securities Administrator, the Seller, the Servicer or the Depositor and which investment letter states that, among other things, such transferee (a) is a “qualified institutional buyer” as defined under Rule 144A, acting for its own account or the accounts of other “qualified institutional buyers” as defined under Rule 144A, and (b) is aware that the proposed transferor intends to rely on the exemption from registration requirements under the Securities Act of 1933, as amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which Opinion of Counsel shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar, the Master Servicer, the Securities Administrator, the Seller, the Servicer or the Depositor and (b) the transferee executes a representation letter, substantially in the form of Exhibit E to the Agreement, and transferor executes a representation letter, substantially in the form of Exhibit F hereto, each acceptable to and in form and substance satisfactory to the Certificate Registrar and

the Depositor certifying the facts surrounding such transfer, which representation letters shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar, the Master Servicer, the Securities Administrator, the Seller, the Servicer or the Depositor and (B) the Certificate of Non-Foreign Status (in substantially the form attached hereto as Exhibit D) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar and the Depositor, which certificate shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar or the Depositor. No certification will be required in connection with the initial transfers of nay such Certificate by the Issuer to the Depositor and by the Depositor to one of its Affiliates. The Holder of a Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust, the Owner Trustee, the Certificate Registrar, the Master Servicer, the Securities Administrator, the Seller, the Servicer and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of Certificates or any interest therein shall be made to any Person unless the Depositor, the Owner Trustee and the Certificate Registrar are provided with an Opinion of Counsel which establishes to the satisfaction of the Depositor, the Owner Trustee, the Certificate Registrar, the Seller, the Servicer and the Master Servicer that 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 and will not subject the Depositor, the Owner Trustee, the Certificate Registrar, the Securities Administrator, the Seller, the Servicer 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 this Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Owner Trustee, the Certificate Registrar, the Securities Administrator, the Seller, the Servicer or the Master Servicer. In lieu of such Opinion of Counsel, a Person acquiring such Certificates may provide a certification in the form of Exhibit G to this Agreement, which the Depositor, the Owner Trustee, the Certificate Registrar, the Securities Administrator, the Seller, the Servicer and the Master Servicer may rely upon without further inquiry or investigation. Neither an Opinion of Counsel nor a certification will be required in connection with the initial transfers of any such Certificate from the Issuer to the Depositor, or by the Depositor to an Affiliate of the Depositor (in which case, the Depositor and such Affiliate, as applicable, shall be deemed to have represented that such party is not a Plan or a Person investing Plan Assets of any Plan).

No offer, sale, transfer, pledge, hypothecation or other disposition (including any pledge, sale or transfer under a repurchase transaction or securities loan) of any Certificate shall be made to any transferee unless, prior to such disposition, the proposed transferor delivers to the Owner Trustee and the Certificate Registrar an Opinion of Counsel, rendered by a law firm generally recognized to be qualified to opine concerning the tax aspects of asset securitization, to the effect that such transfer (including any disposition permitted following any default under any pledge or repurchase transaction) will not cause the Trust to be treated (i) as an association taxable as a corporation for federal income tax and relevant state income and franchise tax purposes, (ii) as a taxable mortgage pool as defined in Section 7701(i) of the Code or (iii) as a “publicly traded partnership” as defined in Treasury Regulation Section 1.7704-1 for federal income tax purposes and relevant state franchise or income tax purposes. Notwithstanding the foregoing, the provisions of this paragraph shall not apply to the initial transfers of the Certificates from the Issuer to the Depositor and the Depositor to an Affiliate of the Depositor.

No offer, sale, transfer or other disposition (including pledge) of any Certificate shall be made to any affiliate of the Depositor or the Issuer, other than the initial transfer of the Certificates to the Depositor and the subsequent transfer of the Certificates to the Seller.

Section 3.05. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate shall be surrendered to the Certificate Registrar, or if the Certificate Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there shall be delivered to the Certificate Registrar and the Owner Trustee such security or indemnity as may be required by them to save each of them harmless, then in the absence of notice to the Certificate Registrar or the Owner Trustee that such Certificate has been acquired by a bona fide purchaser, the Owner Trustee shall execute on behalf of the Trust and the Owner Trustee or the Certificate Registrar, 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 denomination. In connection with the issuance of any new Certificate under this Section 3.05, the Owner Trustee or the Certificate Registrar may require the payment of a sum sufficient to cover any expenses of the Owner Trustee or the Certificate Registrar (including fees and expenses of counsel) and any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Certificate issued pursuant to this Section 3.05 shall constitute conclusive evidence of ownership in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 3.06. Persons Deemed Certificateholders. Prior to due presentation of a Certificate for registration of transfer, the Owner Trustee, the Certificate Registrar or any Certificate Paying Agent may treat the Person in whose name any Certificate is registered in the Certificate Register as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.02 and for all other purposes whatsoever, and none of the Trust, the Owner Trustee, the Certificate Registrar or any Certificate Paying Agent shall be bound by any notice to the contrary.

Section 3.07. Access to List of Certificateholders’ Names and Addresses. The Certificate Registrar shall furnish or cause to be furnished to the Depositor, the Certificate Paying Agent or the Owner Trustee, within 15 days after receipt by the Certificate Registrar of a written request therefor from the Depositor, the Certificate Paying Agent or the Owner Trustee, a list, in such form as the Depositor, the Certificate Paying Agent or the Owner Trustee, as the case may be, may reasonably require, of the names and addresses of the Certificateholders as of the most recent Record Date. Each Holder, by receiving and holding a Certificate, shall be deemed to have agreed not to hold any of the Trust, the Depositor, the Certificate Paying Agent, the Certificate Registrar or the Owner Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived.

Section 3.08. Maintenance of Office or Agency. The Owner Trustee on behalf of the Trust, shall maintain an office or offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Owner Trustee in respect of the Certificates and the Basic Documents may be delivered. The Owner Trustee initially designates the Corporate Trust Office of the Securities Administrator as its office for purposes of delivery of notices. The Owner Trustee shall give prompt written notice to the Depositor, the Certificate Paying Agent, the Certificate Registrar and the

Certificateholders of any change in the location of the Certificate Register or any such office or agency.

Section 3.09. Certificate Paying Agent. (a) The Certificate Paying Agent shall make distributions to Certificateholders from the Certificate Distribution Account on behalf of the Trust in accordance with the provisions of the Certificates and Section 5.01 hereof from payments remitted to the Certificate Paying Agent by the Securities Administrator pursuant to Section 3.05 of the Indenture. The Trust hereby appoints the Securities Administrator as Certificate Paying Agent and the Securities Administrator hereby accepts such appointment and further agrees that it will be bound by the provisions of this Trust Agreement relating to the Certificate Paying Agent and shall:

(i) hold all sums held by it for the payment of amounts due with respect to the Certificates in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(ii) give the Owner Trustee notice of any default by the Trust of which a Responsible Officer of the Certificate Paying Agent has actual knowledge in the making of any payment required to be made with respect to the Certificates;

(iii) at any time during the continuance of any such default, upon the written request of the Owner Trustee forthwith pay to the Owner Trustee on behalf of the Trust all sums so held in Trust by such Certificate Paying Agent;

(iv) not resign from its position as Certificate Paying Agent except that it shall immediately resign as Certificate Paying Agent and forthwith pay to the Owner Trustee on behalf of the Trust all sums held by it in trust for the payment of Certificates if at any time it ceases to meet the standards under this Section 3.09 required to be met by the Certificate Paying Agent at the time of its appointment;

(v) comply with all requirements of the Code with respect to the withholding from any payments made by it on any Certificates of any applicable withholding taxes imposed thereon and with respect to any applicable reporting requirements in connection therewith; and

(vi) not institute bankruptcy proceedings against the Issuer in connection with this Trust Agreement.

(b) The Trust may revoke such power and remove the Certificate Paying Agent if it determines in its sole discretion that the Certificate Paying Agent shall have failed to perform its obligations under this Trust Agreement in any material respect. In the event that ▇▇▇▇▇ Fargo Bank, National Association shall no longer be the Securities Administrator and the Certificate Paying Agent under this Trust Agreement and Paying Agent under the Indenture, the Owner Trustee shall appoint a successor to act as Certificate Paying Agent (which shall be a bank or trust company) and which shall also be the successor Paying Agent under the Indenture. The Owner Trustee shall cause such successor Certificate Paying Agent or any additional Certificate Paying Agent appointed by the Owner Trustee to execute and deliver to the Owner Trustee an instrument to the effect set forth in Section 3.09(a) as it relates to the Certificate Paying Agent.

The Certificate Paying Agent shall return all unclaimed funds to the Trust and upon removal of a Certificate Paying Agent such Certificate Paying Agent shall also return all funds in its possession to the Trust. The provisions of Sections 6.01, 6.04, 6.05, 6.06, 6.07, 6.08 and 7.01 shall apply to the Certificate Paying Agent to the same extent applicable to the Owner Trustee except where the context requires otherwise. Any reference in this Agreement to the Certificate Paying Agent shall include any co-paying agent unless the context requires otherwise.

Authority and Duties of Owner Trustee

Section 4.01. General Authority. The Owner Trustee is authorized and directed to execute and deliver the Basic Documents to which the Trust is to be a party and each certificate or other document attached as an exhibit to or contemplated by the Basic Documents to which the Trust is to be a party and any amendment or other agreement or instrument described herein, as evidenced conclusively by the Owner Trustee's execution thereof. In addition to the foregoing, the Owner Trustee is authorized, but shall not be obligated, except as otherwise provided in this Trust Agreement, to take all actions required of the Trust pursuant to the Basic Documents.

Section 4.02. General Duties. It shall be the duty of the Owner Trustee to discharge (or cause to be discharged) all of its responsibilities pursuant to the terms of this Trust Agreement and the Basic Documents to which the Trust is a party and to administer the Trust in the interest of the Certificateholders, subject to the Basic Documents and in accordance with the provisions of this Trust Agreement.

Section 4.03. Action upon Instruction. (a) Subject to Article IV and in accordance with the terms of the Basic Documents, the Certificateholders may by written instruction direct the Owner Trustee in the management of the Trust. Such direction may be exercised at any time by written instruction of the Certificateholders pursuant to Article IV.

(b) Notwithstanding the foregoing, the Owner Trustee shall not be required to take any action hereunder or under any Basic Document if the Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the Owner Trustee or is contrary to the terms hereof or of any Basic Document or is otherwise contrary to law.

(c) Whenever the Owner Trustee is required to decide between alternative courses of action permitted or required by the terms of this Trust Agreement or under any Basic Document, or in the event that the Owner Trustee is unsure as to the application of any provision of this Trust Agreement or any Basic Document or any such provision is ambiguous as to its application, or is, or appears to be, in conflict with any other applicable provision, or in the event that this Trust Agreement permits any determination by the Owner Trustee or is silent or is incomplete as to the course of action that the Owner Trustee is required to take with respect to a particular set of facts, the Owner Trustee shall promptly give notice (in such form as shall be appropriate under the circumstances) to the Certificateholders requesting instruction as to the course of action to be adopted, and to the extent the Owner Trustee acts in good faith in accordance with any written instruction of the Certificateholders, the Owner Trustee shall not be liable on account of such action to any Person. If the Owner Trustee shall not have received appropriate instruction within 10 days of such notice (or within such shorter period of time as reasonably may be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement or the Basic Documents, as it shall deem to be in the best interests of the

Certificateholders, and the Owner Trustee shall have no liability to any Person for such action or inaction.

Section 4.04. No Duties Except as Specified under Specified Documents or in Instructions. The Owner Trustee shall not have any duty or obligation to manage, make any payment with respect to, register, record, sell, dispose of, or otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from taking any action under, or in connection with, any document contemplated hereby to which the Owner Trustee is a party, except as expressly provided (i) in accordance with the powers granted to and the authority conferred upon the Owner Trustee pursuant to this Trust Agreement, (ii) in accordance with the Basic Documents and (iii) in accordance with any document or instruction delivered to the Owner Trustee pursuant to Section 4.03; and no implied duties or obligations shall be read into this Trust Agreement or any Basic Document against the Owner Trustee.

The Owner Trustee nevertheless agrees that it will, at its own cost and expense, promptly take all action as may be necessary to discharge any liens on any part of the Owner Trust Estate that result from actions by, or claims against, the Owner Trustee that are not related to the ownership or the administration of the Owner Trust Estate.

Section 4.05. Restrictions. (a) The Owner Trustee or the Depositor (or an Affiliate thereof) shall not take any action (x) that is inconsistent with the purposes of the Trust set forth in Section 2.03, (y) that, to the actual knowledge of the Owner Trustee based on an Opinion of Counsel rendered by a law firm generally recognized to be qualified to opine concerning the tax aspects of asset securitization, would result in the Trust becoming taxable as a corporation for federal income tax purposes or (z) would result in the amendment or modification of the Basic Documents or this Trust Agreement. The Certificateholders shall not direct the Owner Trustee to take action that would violate the provisions of this Section 4.05.

(b) The Owner Trustee shall not convey or transfer any of the Trust's properties or assets, including those included in the Trust Estate, to any person unless (a) it shall have received an Opinion of Counsel rendered by a law firm generally recognized to be qualified to opine concerning the tax aspects of asset securitization to the effect that such transaction will not have any material adverse tax consequence to the Trust or any Certificateholder and (b) such conveyance or transfer shall not violate the provisions of Section 3.16(b) of the Indenture.

With respect to the following matters, the Owner Trustee shall not take action unless at least 30 days before the taking of such action, the Owner Trustee shall have notified the Certificateholders in writing of the proposed action and the Certificateholders shall not have notified the Owner Trustee in writing prior to the 30th day after such notice is given that such Certificateholders have withheld consent or provided alternative direction:

respect to the aforementioned claims or lawsuits for collection of cash distributions due and owing under the Mortgage Loans);

(b) the election by the Trust to file an amendment to the Certificate of Trust (unless such amendment is required to be filed under the Statutory Trust Statute);

(c) the amendment of the Indenture by a supplemental indenture in circumstances where the consent of any Noteholder is required;

(d) the amendment of the Indenture by a supplemental indenture in circumstances where the consent of any Noteholder is not required and such amendment materially adversely affects the interest of the Certificateholders; and

This paragraph shall survive for one year following termination of this Trust Agreement.

Section 4.09. Restrictions on Certificateholders' Power. The Certificateholders shall not direct the Owner Trustee to take or to refrain from taking any action if such action or inaction would be contrary to any obligation of the Trust or the Owner Trustee under this Trust Agreement or any of the Basic Documents or would be contrary to Section 2.03, nor shall the Owner Trustee be obligated to follow any such direction, if given.

Section 4.10. Majority Control. Except as expressly provided herein, any action that may be taken by the Certificateholders under this Trust Agreement may be taken by the Holders of Certificates evidencing not less than a majority Percentage Interest of the Certificates. Except as expressly provided herein, any written notice of the Certificateholders delivered pursuant to this Trust Agreement shall be effective if signed by Holders of Certificates evidencing not less than a majority Percentage Interest of the Certificates at the time of the delivery of such notice.

Section 4.11. Optional Redemption. Upon receipt of written instructions provided to the Owner Trustee by the Majority Certificateholder, the Owner Trustee shall cause the Issuer to

redeem the Notes in accordance with Section 8.07 of the Indenture and shall provide all necessary notices on behalf of the Issuer to effect the foregoing, provided that such Holder shall deposit with the Securities Administrator an amount equal to the aggregate redemption price specified under Section 8.07 of the Indenture.

(a) On each Payment Date, the Certificate Paying Agent shall in accordance with the directions of the Securities Administrator given pursuant to the Indenture distribute to the Certificateholders, on a pro rata basis based on the Certificate Percentage Interests thereof, all funds on deposit in the Certificate Distribution Account and available therefor (as provided in Section 3.05 of the Indenture) for such Payment Date as reduced by any amount owing to the Owner Trustee hereunder and any Expenses of the Trust remaining unpaid.

(b) In the event that any withholding tax is imposed on the distributions (or allocations of income) to a Certificateholder, such tax shall reduce the amount otherwise distributable to the Certificateholder in accordance with this Section 5.01. The Certificate Paying Agent is hereby authorized and directed to retain or cause to be retained from amounts otherwise distributable to the Certificateholders sufficient funds for the payment of any tax that is legally owed by the Trust (but such authorization shall not prevent the Owner Trustee from contesting any such tax in appropriate proceedings, and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The amount of any withholding tax imposed with respect to a Certificateholder shall be treated as cash distributed to such Certificateholder at the time it is withheld by the Certificate Paying Agent and remitted to the appropriate taxing authority. If there is a possibility that withholding tax is payable with respect to a distribution (such as a distribution to a non-U.S. Certificateholder), the Certificate Paying Agent may in its sole discretion withhold such amounts in accordance with this paragraph (b).

Section 5.02. Method of Payment. Subject to Section 8.01(c), distributions required to be made to Certificateholders on any Payment Date as provided in Section 5.01 shall be made to each Certificateholder of record on the preceding Record Date by wire transfer, in immediately available funds, to the account of such Holder at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have provided to the Certificate Registrar appropriate written instructions at least five Business Days prior to such Payment Date or, if not, by check mailed to such Certificateholder at the address of such Holder appearing in the Certificate Register.

Section 5.03. Tax Returns. The Securities Administrator shall (a) maintain (or cause to be maintained) the books of the Trust on a calendar year basis using the accrual method of accounting, (b) deliver (or cause to be delivered) to each Noteholder and Certificateholder as may be required by the Code and applicable Treasury regulations, such information as may be required to enable each Certificateholder to prepare its federal and state income tax returns, (c) prepare and file or cause to be prepared and filed such tax returns relating to the Trust as may be required by the Code and applicable Treasury regulations (making such elections as may from time to time be required or appropriate under any applicable state or federal statutes, rules or regulations) and (d) collect or cause to be collected any withholding tax as described in and in

accordance with Section 5.01 of this Trust Agreement with respect to income or distributions to Certificateholders and prepare or cause to be prepared the appropriate forms relating thereto; provided, however, that the Securities Administrator shall not be required to compute the Issuer's gross income except to the extent it can do so without unreasonable effort or expense based upon income statements furnished to it and provided, further, that the Securities Administrator shall not be required to prepare and file partnership tax returns on behalf of the Issuer unless the Securities Administrator receives (i) an Opinion of Counsel reasonably satisfactory to it (which shall not be at the Securities Administrator's expense, but shall be at the expense of the Depositor or other party furnishing such opinion) as to the necessity of such filings, and (ii) reasonable additional compensation for the preparation and filing of such additional returns. The Owner Trustee hereby grants permission to the Securities Administrator to sign all tax and information returns prepared by the Securities Administrator pursuant to this Section 5.03 at the request of the Securities Administrator, and in doing so shall rely entirely upon, and shall have no liability for information or calculations provided by, the Securities Administrator.

If such corporation shall publish reports of condition at least annually pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purpose of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of this Section 9.01, the Owner Trustee shall resign immediately in the manner and with the effect specified in Section 9.02.

Section 9.02. Replacement of Owner Trustee. The Owner Trustee may at any time resign and be discharged from the trusts hereby created by giving 30 days prior written notice thereof to the Depositor. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor Owner Trustee, by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Owner Trustee and to the successor Owner Trustee. If no successor Owner Trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Owner Trustee may petition any court of competent jurisdiction for the appointment of a successor Owner Trustee.

If at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of Section 9.01 and shall fail to resign after written request therefor by the Depositor, or if at any time the Owner Trustee shall be legally unable to act, or shall be adjudged bankrupt or insolvent, or a receiver of the Owner Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Owner Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor may remove the Owner Trustee.

Any resignation or removal of the Owner Trustee and appointment of a successor Owner Trustee pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor Owner Trustee pursuant to Section 9.03 and payment of all fees and expenses owed to the outgoing Owner Trustee. The Depositor shall provide notice of such resignation or removal of the Owner Trustee to each of the Rating Agencies.

Section 9.03. Successor Owner Trustee. Any successor Owner Trustee appointed pursuant to Section 9.02 shall execute, acknowledge and deliver to the Indenture Trustee and to its predecessor Owner Trustee an instrument accepting such appointment under this Trust Agreement, and thereupon the resignation or removal of the predecessor Owner Trustee shall

become effective, and such successor Owner Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Trust Agreement, with like effect as if originally named as Owner Trustee. The predecessor Owner Trustee shall upon payment of its fees and expenses deliver to the successor Owner Trustee all documents and statements and monies held by it under this Trust Agreement; and the predecessor Owner Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor Owner Trustee all such rights, powers, duties and obligations.

No successor Owner Trustee shall accept appointment as provided in this Section 9.03 unless at the time of such acceptance such successor Owner Trustee shall be eligible pursuant to Section 9.01.

Upon acceptance of appointment by a successor Owner Trustee pursuant to this Section 9.03, the Owner Trustee shall mail notice thereof to all Certificateholders, the Indenture Trustee, the Noteholders and the Rating Agencies.

Section 9.04. Merger or Consolidation of Owner Trustee. Any Person into which the Owner Trustee 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 Owner Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Owner Trustee, shall be the successor of the Owner Trustee hereunder, without the execution or filing of any instrument or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, that such Person shall be eligible pursuant to Section 9.01 and, provided, further, that the Owner Trustee shall mail notice of such merger or consolidation to the Rating Agencies.

Section 9.05. Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions of this Trust Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Owner Trust Estate may at the time be located, the Owner Trustee shall have the power and shall execute and deliver all instruments to appoint one or more Persons to act as co-trustee, jointly with the Owner Trustee, or as separate trustee or trustees, of all or any part of the Owner Trust Estate, and to vest in such Person, in such capacity, such title to the Trust or any part thereof and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Owner Trustee may consider necessary or desirable. No co-trustee or separate trustee under this Trust Agreement shall be required to meet the terms of eligibility as a successor Owner Trustee pursuant to Section 9.01 and no notice of the appointment of any co-trustee or separate trustee shall be required pursuant to Section 9.03.

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

(a) All rights, powers, duties and obligations conferred or imposed upon the Owner Trustee shall be conferred upon and exercised or performed by the Owner Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Owner Trustee joining in such act), except to the

extent that under any law of any jurisdiction in which any particular act or acts are to be performed, the Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Owner Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Owner Trustee;

(b) No trustee under this Trust Agreement shall be personally liable by reason of any act or omission of any other trustee under this Trust Agreement; and

Any notice, request or other writing given to the Owner Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Trust Agreement and the conditions of this Article. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Owner Trustee or separately, as may be provided therein, subject to all the provisions of this Trust Agreement, specifically including every provision of this Trust Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Owner Trustee. Each such instrument shall be filed with the Owner Trustee.

Any separate trustee or co-trustee may at any time appoint the Owner Trustee as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Trust Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Owner Trustee, to the extent permitted by law, without the appointment of a new or successor co-trustee or separate trustee.

MORTGAGEIT TRUST SERIES 2005-4

Evidencing a fractional undivided equity interest in the Owner Trust Estate, the property of which consists primarily of the Mortgage Loans in MortgageIT Trust 2005-4 (the “Trust”), a Delaware statutory trust formed by MORTGAGEIT SECURITIES CORP., as depositor, pursuant to the Trust Agreement referred to below.

This certifies that __________________ is the registered owner of the Percentage Interest represented hereby.

The Trust was created pursuant to a Short Form Trust Agreement, dated as of August 18, 2005, between the Depositor and Wilmington Trust Company, as owner trustee (the “Owner Trustee”, which term includes any successor entity under the Trust Agreement) (the “Short Form Trust Agreement”) as amended and restated by the Amended and Restated Trust Agreement dated as of August 24, 2005 (as amended and supplemented from time to time, together with the Short Form Trust Agreement, the “Trust Agreement”) among the Depositor, the Owner Trustee and ▇▇▇▇▇ Fargo Bank, National Association, in its capacity as Securities Administrator, as certificate registrar and certificate paying agent, a summary of certain of the pertinent provisions of which is set forth hereinafter. This Certificate is issued under and is subject to the terms, provisions and conditions of the Trust Agreement, to which Trust Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

This Certificate is one of a duly authorized issue of Trust Certificates, Series 2005-4 (herein called the “Certificates”) issued under the Trust Agreement to which reference is hereby made for a statement of the respective rights thereunder of the Depositor, the Owner Trustee and the Holders of the Certificates and the terms upon which the Certificates are executed and delivered. All terms used in this Certificate which are defined in the Trust Agreement shall have the meanings assigned to them in the Trust Agreement. The Owner Trust Estate consists of the Mortgage Loans in the MortgageIT Trust 2005-4. The rights of the Holders of the Certificates are subordinated to the rights of the Holders of the Notes, as set forth in the Indenture.

There will be distributed on the 25th day of each month or, if such 25th day is not a Business Day, the next Business Day (each, a “Payment Date”), commencing on September 26, 2005, 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 such Payment Date (the “Record Date”),

such Certificateholder's Percentage Interest in the amount to be distributed to Certificateholders on such Payment Date.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Payment Account that have been released from the Lien of the Indenture for payment hereunder and that neither the Owner Trustee in its individual capacity nor the Depositor is personally liable to the Certificateholders for any amount payable under this Certificate or the Trust Agreement or, except as expressly provided in the Trust Agreement, subject to any liability under the Trust Agreement.

The Holder of this Certificate acknowledges and agrees that its rights to receive distributions in respect of this Certificate are subordinated to the rights of the Noteholders as described in the Indenture, dated as of August 24, 2005, among the Trust, Deutsche Bank National Trust Company, as Indenture Trustee and ▇▇▇▇▇ Fargo Bank, National Association, as Securities Administrator (the “Indenture”).

The Depositor and each Certificateholder, by acceptance of a Certificate, agree to treat, and to take no action inconsistent with the treatment of, the Certificates for federal, state and local income tax purposes as an equity interest in the Trust.

Each Certificateholder, by its acceptance of a Certificate, covenants and agrees that such Certificateholder will not at any time institute against the Depositor, or join in any institution against the Depositor or the Trust of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations relating to the Certificates, the Notes, the Trust Agreement or any of the Basic Documents.

Distributions on this Certificate will be made as provided in the Trust Agreement by the Certificate Paying Agent by wire transfer or check mailed to the Certificateholder of record in the Certificate Register without the presentation or surrender of this Certificate or the making of any notation hereon. Except as otherwise provided in the Trust Agreement and notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Certificate Paying Agent of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency maintained by the Certificate Registrar for that purpose by the Trust, as provided in Section 3.08 of the Trust Agreement.

Notwithstanding the above, the final distribution on this Certificate will be made after due notice of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency specified in such notice.

The Majority Certifcateholder may redeem the Notes on any Payment Date on or after the Payment Date on which the aggregate Scheduled Principal Balance of the Mortgage Loans as of the end of the prior Due Period is less than or equal to 20% of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-off Date.

and laws. In the event of any such transfer, the Certificate Registrar or the Depositor shall prior to such transfer require the transferee to execute (A) either (i) (a) an investment letter in substantially the form attached to the Agreement as Exhibit C (or in such form and substance reasonably satisfactory to the Certificate Registrar and the Depositor) which investment letter shall not be an expense of the Trust, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Master Servicer, the Seller, the Servicer or the Depositor and which investment letter states that, among other things, such transferee (1) is a “qualified institutional buyer” as defined under Rule 144A, acting for its own account or the accounts of other “qualified institutional buyers” as defined under Rule 144A, and (2) is aware that the proposed transferor intends to rely on the exemption from registration requirements under the Securities Act of 1933, as amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which Opinion of Counsel shall not be an expense of the Trust, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Master Servicer, the Seller, the Servicer or the Depositor and (b) the transferee executes a representation letter, substantially in the form of Exhibit D to the Agreement, and the transferor executes a representation letter, substantially in the form of Exhibit F to the Agreement, each acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor certifying the facts surrounding such transfer, which representation letters shall not be an expense of the Trust, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Master Servicer, the Seller, the Servicer or the Depositor and (B) the Certificate of Non-Foreign Status (in substantially the form attached to the Agreement as Exhibit D) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar and the Depositor, which certificate shall not be an expense of the Trust, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer or the Depositor. The Holder of a Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust, the Owner Trustee, the Indenture Trustee, the Certificate Paying Agent, the Certificate Registrar, the Master Servicer, the Seller, the Servicer and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of Certificates or any interest therein shall be made to any Person unless the Depositor, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer and the Master Servicer are provided with an Opinion of Counsel which establishes to the satisfaction of the Depositor, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer and the Master Servicer that 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 and will not subject the Depositor, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer 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 Trust Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer or the Master Servicer. In lieu of such Opinion of Counsel, a Person may provide a certification in the form of Exhibit G to the Agreement, which the Depositor, the Owner Trustee, the Securities Administrator, the Certificate Registrar, the Seller, the Servicer and the Master Servicer may rely upon without

further inquiry or investigation. Neither an Opinion of Counsel nor a certification will be required in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor (in which case, the Depositor or any affiliate thereof shall have deemed to have represented that such affiliate is not a Plan or a Person investing Plan Assets of any Plan) and the Owner Trustee shall be entitled to conclusively rely upon a representation (which, upon the request of the Owner Trustee, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor.

No offer, sale, transfer, pledge, hypothecation or other disposition (including any pledge, sale or transfer under a repurchase transaction or securities loan) of any Certificate shall be made to any transferee unless, prior to such disposition, the proposed transferor delivers to the Certificate Registrar and the Owner Trustee an Opinion of Counsel, rendered by a law firm generally recognized to be qualified to opine concerning the tax aspects of asset securitization, to the effect that such transfer (including any disposition permitted following any default under any pledge or repurchase transaction) will not cause the Trust to be treated (i) as an association taxable as a corporation for federal income tax and relevant state and local income and franchise tax purposes, (ii) as a taxable mortgage pool as defined in Section 7701(i) of the Code or (iii) as a “publicly traded partnership” as defined in Treasury Regulation Section 1.7704-1 for federal income tax purposes and relevant state and local franchise or income tax purposes.

Reference is hereby made to the further provisions of this Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon shall have been executed by an authorized officer of the Owner Trustee, or an authenticating agent by manual signature, this Certificate shall not entitle the Holder hereof to any benefit under the Trust Agreement or be valid for any purpose.

THIS CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

IN WITNESS WHEREOF, the Owner Trustee, on behalf of the Trust and not in its individual capacity, has caused this Certificate to be duly executed.

A copy of the Trust Agreement may be examined by any Certificateholder upon written request during normal business hours at the principal office of the Depositor and at such other places, if any, designated by the Depositor.

The Trust Agreement permits the amendment thereof as specified below, provided that any amendment be accompanied by an Opinion of Counsel to the Owner Trustee to the effect that such amendment complies with the provisions of the Trust Agreement and, if MortgageIT Holdings, Inc. was not the Majority Certificateholder, would not cause the Trust to be subject to an entity level tax. If the purpose of the amendment is to correct any mistake, eliminate any inconsistency, cure any ambiguity or deal with any matter not covered, it shall not be necessary to obtain the consent of any Holder, but the Owner Trustee shall be furnished with a letter from each of the Rating Agencies that the amendment will not result in the downgrading or withdrawal of the rating then assigned to any Note or the rating then assigned to any Note.

If the purpose of the amendment is to add or eliminate or change any provision of the Trust Agreement, other than as specified in the preceding two sentences, the amendment shall require either (a) a letter from each of the Rating Agencies that the amendment will not result in the downgrading or withdrawal of the rating then assigned to any Note or the rating then assigned to any Note or (b) the consent of Holders of the Certificates evidencing a majority of the Percentage Interests of the Certificates and the Indenture Trustee; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the time of, payments received that are required to be distributed on any Certificate without the consent of the related Certificateholder, or (ii) reduce the aforesaid percentage of Certificates the Holders of which are required to consent to any such amendment without the consent of the Holders of all such Certificates then outstanding.

As provided in the Trust Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies of the Certificate Registrar maintained by the Trust, as provided in the Trust Agreement, accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Certificates of authorized denominations evidencing the same aggregate interest in the Trust

will be issued to the designated transferee. The initial Certificate Registrar appointed under the Trust Agreement is ▇▇▇▇▇ Fargo Bank, National Association.

Except as provided in the Trust Agreement, the Certificates are issuable only in a minimum Certificate Percentage Interest of 10%. As provided in the Trust Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate denomination, as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Owner Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

The Owner Trustee, the Certificate Paying Agent, the Certificate Registrar and any agent of the Owner Trustee, the Certificate Paying Agent, or the Certificate Registrar may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Owner Trustee, the Certificate Paying Agent, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.
