                                    Covenants

         Section 3.01 MAINTENANCE OF PAYMENT ACCOUNT. The Securities
Administrator shall maintain the Payment Account established pursuant to Section
4.04 of the Sale and Servicing Agreement in accordance with the requirements of
such Section. The Securities Administrator shall make all payments of principal
of and interest on the Notes (subject to Section 3.03) as provided in Section
3.05 herein from monies on deposit in the Payment Account.

         Section 3.02 MAINTENANCE OF OFFICE OR AGENCY. The Issuer will maintain
an office or agency where, subject to satisfaction of conditions set forth
herein, Notes may be surrendered for registration of transfer or exchange, and
where notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Issuer hereby initially appoints the Securities
Administrator to serve as its agent for the foregoing purposes. If at any time
the Issuer shall fail to maintain any such office or agency or shall fail to
furnish the Securities Administrator with the address thereof, such surrenders
may be made at the Corporate Trust Office and notices and demands may be made or
delivered to the Corporate Trust Office, and the Issuer hereby appoints the
Securities Administrator as its agent to receive all such surrenders, notices
and demands.

         Section 3.03 MONEY FOR PAYMENTS TO BE HELD IN TRUST; PAYING AGENT. (a)
As provided in Section 3.01, all payments of amounts due and payable with
respect to any Notes that are to be made from amounts withdrawn from the Payment
Account pursuant to Section 3.05 shall be made on behalf of the Issuer by the
Securities Administrator or by the Paying Agent, based on information provided
by the Securities Administrator to the Paying Agent and no amounts so withdrawn
from the Payment Account for payments of Notes shall be paid over to the Issuer
except as provided in this Section 3.03. The Securities Administrator shall
calculate the amount to be distributed to each Class and, based on such amounts,
the Securities Administrator shall determine the amount to be distributed to
each Noteholder. All of the Securities Administrator's calculations of payments
shall be based solely on information provided to the Securities Administrator by
the Master Servicer pursuant to Section 3.01 of the Sale and Servicing
Agreement. Neither the Securities Administrator nor the Indenture Trustee shall
be required to confirm, verify or recompute any such information but shall be
entitled to rely conclusively on such information. The Issuer hereby appoints
the Securities Administrator as its initial Paying Agent.

         The Issuer will cause each Paying Agent, other than the Securities
Administrator, to execute and deliver to the Securities Administrator and the
Indenture Trustee an instrument in which such Paying Agent shall agree with the
Securities Administrator and the Indenture Trustee (and if the Securities
Administrator or the Indenture Trustee acts as Paying Agent it hereby so
agrees), subject to the provisions of this Section 3.03, that such Paying Agent
will:

                  (i)      hold all sums held by it for the payment of amounts
         due with respect to the Notes 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 and pay such sums to such
         Persons as herein provided;


                                       7
<PAGE>


                  (ii)     give the Securities Administrator and the Indenture
         Trustee notice of any default by the Issuer of which it has actual
         knowledge in the making of any payment required to be made with respect
         to the Notes;

                  (iii)    at any time during the continuance of any such
         default, upon the written request of either the Securities
         Administrator or the Indenture Trustee, forthwith pay to the Securities
         Administrator all sums so held in trust by such Paying Agent;

                  (iv)     immediately resign as Paying Agent and forthwith pay
         to the Securities Administrator all sums held by it in trust for the
         payment of Notes if at any time it ceases to meet the standards
         required to be met by a 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 Notes of any
         applicable withholding taxes imposed thereon and with respect to any
         applicable reporting requirements in connection therewith; and

                  (vi)     not commence a bankruptcy proceeding against the
         Issuer in connection with this Indenture.

         The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Request direct any Paying Agent to pay to the Securities Administrator all sums
held in trust by such Paying Agent, such sums to be held by the Securities
Administrator upon the same trusts as those upon which the sums were held by
such Paying Agent; and upon such payment by any Paying Agent to the Securities
Administrator such Paying Agent shall be released from all further liability
with respect to such money.

         Subject to applicable laws with respect to escheat of funds, any money
held by the Securities Administrator or any Paying Agent in trust for the
payment of any amount due with respect to any Note and remaining unclaimed for
one year after such amount has become due and payable shall be discharged from
such trust and be paid to the Issuer; and the Holder of such Note shall
thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof (but only to the extent of the amounts so paid to the Issuer),
and all liability of the Securities Administrator or such Paying Agent with
respect to such trust money shall thereupon cease; provided, however, that the
Securities Administrator or such Paying Agent, before being required to make any
such repayment, shall at the expense and direction of the Issuer cause to be
published once, in an Authorized Newspaper published in the English language,
notice that such money remains unclaimed and that, after a date specified
therein which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the Issuer.
The Securities Administrator may also adopt and employ, at the expense and
direction of the Issuer, any other reasonable means of notification of such
repayment (including, but not limited to, mailing notice of such repayment to
Holders whose Notes have been called but have not been surrendered for
redemption or whose right to or interest in monies due and payable but not
claimed is determinable from the records of the Securities Administrator or of
any Paying Agent, at the last address of record for each such Holder).

America, in which case the Issuer will keep in full effect its existence, rights

         the Collateral, free and clear of any lien, claim or encumbrance of any
         Person.

                  (iv)     The Issuer has taken all steps necessary to cause the
         Indenture Trustee to become the account holder of the Collateral.

                  (v)      Other than the security interest granted to the
         Indenture Trustee pursuant to this Indenture, the Issuer has not
         pledged, assigned, sold, granted a security interest in, or otherwise
         conveyed any of the Collateral.

                  (vi)     The Collateral is not in the name of any Person other
         than the Issuer or the Indenture Trustee. The Issuer has not consented
         to the bank maintaining the Collateral to comply with instructions of
         any Person other than the Indenture Trustee.

         (b)      With respect to any Collateral in which a security interest
may be perfected by filing, the Issuer has not authorized the filing of, and is
not aware of any financing statements against, the Issuer, that include a
description of collateral covering such Collateral, other than any financing
statement relating to the security interest granted to the Indenture Trustee
hereunder or that has been terminated. The Issuer is not aware of any judgment
or tax lien filings against the Issuer.

         (c)      The Issuer has caused or will have caused, within ten days,
the filing of all appropriate financing statements in the proper filing office
in the appropriate jurisdictions under applicable law in order to perfect the
security interest in all Collateral granted to the Indenture Trustee hereunder
in which a security interest may be perfected by filing. Any financing statement
that is filed in connection with this Section 3.26 shall contain a statement
that a purchase or security interest in any collateral described therein will
violate the rights of the secured party named in such financing statement.

         (d)      The foregoing representations may not be waived and shall
survive the issuance of the Notes.

         Section 3.27 ALLOCATION OF REALIZED LOSSES. (a) Prior to each Payment
Date, the Master Servicer shall determine, based solely on information provided
to it by the Servicer, the total amount of Realized Losses that occurred during
the related Prepayment Period.

         (b)      Any Realized Losses on the Mortgage Loans will be allocated or
covered on any payment date as follows: first, to the related Net Monthly Excess
Cashflow, as part of the related Undercollateralization Amount and related
Overcollateralization Increase Amount for that Payment Date as provided in
Section 3.05 hereof; second, to the non-related Net Monthly Excess Cashflow as
part of the related Undercollateralization Amount and related
Overcollateralization Increase Amount for that Payment Date as provided in
Section 3.05 hereof; third, in reduction of the related Overcollateralized
Amount until reduced to zero; fourth, in reduction of the non-


                                       20
<PAGE>


related Overcollateralized Amount until reduced to zero (meaning, no losses will
be allocated to the Notes until the aggregate Note Principal Balance of the
Notes equals the aggregate Scheduled Principal Balance of the Mortgage Loans);
and fifth, with respect to any Realized Losses on the Group 1 Loans, to the
Class 1-B-2, Class 1-B-1, Class 1-M-2, Class 1-M-1, Class 1-A-2 and Class 1-A-1
Notes, in that order, and with respect to any Realized Losses on the Group 2
Loans, to the Class 2-B-1, Class 2-M-2, Class 2-M-1 and Class 2-A Notes, in that
order, in each case in reduction of the Note Principal Balance thereof, until
the Note Principal Balance thereof has been reduced to zero. All Realized Losses
allocated to a Class of Notes will be allocated in proportion to the Percentage
Interests evidenced thereby.

         (c)      In addition, in the event that the Securities Administrator
receives any Subsequent Recoveries from the Servicer, the Securities
Administrator shall deposit such funds into the Payment Account in accordance
with Section 4.04 of the Sale and Servicing Agreement. If, after taking into
account such Subsequent Recoveries, the amount of a Realized Loss is reduced,
the amount of such Subsequent Recoveries will be applied to increase the Note
Principal Balance of the related Class of Notes with the highest payment
priority to which Realized Losses have been allocated and not previously
reimbursed through the payment of an Allocated Realized Loss Amount pursuant to
Section 3.05(d)(v) and (vi) or (g)(v) and (vi) but not by more than the amount
of Realized Losses previously allocated to such Class of Notes pursuant to this
Section 3.27. The amount of any remaining Subsequent Recoveries will be applied
to sequentially increase the Note Principal Balance of the Class of Notes,
beginning with the Class of Notes with the related next highest payment
priority, up to the amount of such Realized Losses previously allocated (but
only to the extent not previously reimbursed through the payment of an Allocated
Realized Loss Amount pursuant to Section 3.05(d) (v) and (vi) or (g)(v) and
(vi)) to such Class of Notes pursuant to this Section 3.27. Holders of such
Notes will not be entitled to any payment in respect of current interest on the
amount of such increases for any Accrual Period preceding the Payment Date on
which such increase occurs. Any such increases shall be applied to the Note
Principal Balance of each Class of Notes in accordance with its respective
Percentage Interest.

                                   ARTICLE IV

               The Notes; Satisfaction and Discharge of Indenture

         Section 4.01 THE NOTES. Each Class of Notes shall be registered in the
name of a nominee designated by the Depository. Beneficial Owners will hold
interests in the Notes through the book-entry facilities of the Depository in
minimum initial Note Principal Balances of $25,000 and integral multiples of
$1,000 in excess thereof.

         The Indenture Trustee and Securities Administrator may for all purposes
(including the making of payments due on the Notes) deal with the Depository as
the authorized representative of the Beneficial Owners with respect to the Notes
for the purposes of exercising the rights of Holders of the Notes hereunder.
Except as provided in the next succeeding paragraph of this Section 4.01, the
rights of Beneficial Owners with respect to the Notes shall be limited to those
established by law and agreements between such Beneficial Owners and the
Depository and Depository Participants. Except as provided in Section 4.08
hereof, Beneficial Owners shall not be entitled to definitive certificates for
the Notes as to which they are the Beneficial Owners. Requests and directions
from, and votes of, the Depository as Holder of the Notes shall not be deemed
inconsistent if they are made with respect to different Beneficial Owners. The
Securities Administrator may establish a reasonable record date in connection
with solicitations of consents from or voting by Noteholders and give notice to
the Depository of such record date. Without the consent of the Issuer and the
Securities Administrator, no Note may be transferred by the Depository except to
a successor Depository that agrees to hold such Note for the account of the
Beneficial Owners.

         In the event the Depository Trust Company resigns or is removed as
Depository, the Depositor may appoint a successor Depository. If no successor
Depository has been appointed within 30 days of the effective date of the
Depository's resignation or removal, each Beneficial Owner shall be entitled to
certificates representing the Notes it beneficially owns in the manner
prescribed in Section 4.08.

         The Notes shall, on original issue, be executed on behalf of the Issuer
by the Owner Trustee, not in its individual capacity but solely as Owner
Trustee, authenticated by the Securities Administrator and delivered by the
Securities Administrator to or upon the order of the Issuer.

         Section 4.02 REGISTRATION OF AND LIMITATIONS ON TRANSFER AND EXCHANGE
OF NOTES; APPOINTMENT OF NOTE REGISTRAR AND CERTIFICATE REGISTRAR. The Issuer
shall cause to be kept at the office of the Note Registrar (which shall be the
office specified in Section 3.02) a Note Register in which, subject to such
reasonable regulations as it may prescribe, the Note Registrar shall provide for
the registration of Notes and of transfers and exchanges of Notes as herein
provided.

         Subject to the restrictions and limitations set forth below, upon
surrender for registration or transfer of any Note at the office specified in
Section 3.02, the Issuer shall execute and the Note Registrar shall authenticate
and deliver, in the name of the designated transferee or transferees, one or
more new Notes in authorized initial Note Principal Balances evidencing the same
Class and aggregate Percentage Interests.


                                       22
<PAGE>


         Subject to the foregoing, at the option of the Noteholders, Notes may
be exchanged for other Notes of like tenor and in authorized initial Note
Principal Balances evidencing the same Class and aggregate Percentage Interests
upon surrender of the Notes to be exchanged at the office specified in Section
3.02. Whenever any Notes are so surrendered for exchange, the Issuer shall
execute and the Securities Administrator shall authenticate and deliver the
Notes which the Noteholder making the exchange is entitled to receive. Each Note
presented or surrendered for registration of transfer or exchange shall (if so
required by the Note Registrar) be duly endorsed by, or be accompanied by a
written instrument of transfer in form reasonably satisfactory to the Note
Registrar duly executed by the Holder thereof or his attorney duly authorized in
writing with such signature guaranteed by a commercial bank or trust company
located or having a correspondent located in the city of New York. Notes
delivered upon any such transfer or exchange will evidence the same obligations,
and will be entitled to the same rights and privileges, as the Notes
surrendered.

         No service charge shall be made for any registration of transfer or
exchange of Notes, but the Note Registrar shall require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes.

         The Issuer hereby appoints the Securities Administrator as (i)
Certificate Registrar to keep at the office of its designated agent as specified
in Section 3.02, a Certificate Register pursuant to Section 3.04 of the Trust
Agreement 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 thereof pursuant to Section 3.04 of the Trust
Agreement and (ii) Note Registrar under this Indenture. The Securities
Administrator hereby accepts such appointments.

         Section 4.03 MUTILATED, DESTROYED, LOST OR STOLEN NOTES. If (i) any
mutilated Note is surrendered to the Securities Administrator, or the Securities
Administrator receives evidence to its satisfaction of the destruction, loss or
theft of any Note, and (ii) there is delivered to the Securities Administrator
such security or indemnity as may be required by it to hold the Issuer, the
Indenture Trustee and the Securities Administrator harmless, then, in the
absence of notice to the Issuer, the Note Registrar or the Securities
Administrator that such Note has been acquired by a bona fide purchaser, and
provided that the requirements of Section 8-405 of the UCC are met, the Issuer
shall execute, and upon its request the Securities Administrator shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a replacement Note; provided, however, that if
any such destroyed, lost or stolen Note, but not a mutilated Note, shall have
become or within seven days shall be due and payable, instead of issuing a
replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so
due or payable without surrender thereof. If, after the delivery of such
replacement Note or payment of a destroyed, lost or stolen Note pursuant to the
proviso to the preceding sentence, a bona fide purchaser of the original Note in
lieu of which such replacement Note was issued presents for payment such
original Note, the Issuer and the Securities Administrator shall be entitled to
recover such replacement Note (or such payment) from the Person to whom it was
delivered or any Person taking such replacement Note from such Person to whom
such replacement Note was delivered or any assignee of such Person, except a
bona fide purchaser, and shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the Issuer, the Indenture Trustee or the Securities Administrator in
connection therewith.


                                       23
<PAGE>


         Upon the issuance of any replacement Note under this Section 4.03, the
Issuer may require the payment by the Holder of such Note of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Securities Administrator) connected therewith.

         Every replacement Note issued pursuant to this Section 4.03 in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Issuer, whether or not the
mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

         The provisions of this Section 4.03 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes.

         Section 4.04 PERSONS DEEMED OWNERS. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Securities Administrator,
the Paying Agent and any agent of the Issuer or the Securities Administrator may
treat the Person in whose name any Note is registered (as of the day of
determination) as the owner of such Note for the purpose of receiving payments
of principal of and interest, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Issuer, the
Indenture Trustee, the Securities Administrator, the Paying Agent or any agent
of the Issuer, the Indenture Trustee or the Securities Administrator shall be
affected by notice to the contrary.

         Section 4.05 CANCELLATION. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Securities Administrator, be delivered to the Securities
Administrator and shall be promptly cancelled by the Securities Administrator.
The Issuer may at any time deliver to the Securities Administrator for
cancellation any Notes previously authenticated and delivered hereunder which
the Issuer may have acquired in any manner whatsoever, and all Notes so
delivered shall be promptly cancelled by the Securities Administrator. No Notes
shall be authenticated in lieu of or in exchange for any Notes cancelled as
provided in this Section 4.05, except as expressly permitted by this Indenture.
All cancelled Notes may be held or disposed of by the Securities Administrator
in accordance with its standard retention or disposal policy as in effect at the
time unless the Issuer shall direct by an Issuer Request that they be destroyed
or returned to it; provided, however, that such Issuer Request is timely and the
Notes have not been previously disposed of by the Securities Administrator.

         Section 4.06 BOOK-ENTRY NOTES. The Notes, upon original issuance, will
be issued in the form of typewritten Notes representing the Book-Entry Notes, to
be delivered to The Depository Trust Company, the initial Depository, by, or on
behalf of, the Issuer. The Notes shall initially be registered on the Note
Register in the name of Cede & Co., the nominee of the initial Depository, and
no Beneficial Owner will receive a Definitive Note representing such Beneficial
Owner's interest in such Note, except as provided in Section 4.08. With respect
to such Notes, unless and until definitive, fully registered Notes (the
"Definitive Notes") have been issued to Beneficial Owners pursuant to Section
4.08:


                                       24
<PAGE>


                  (i)      the provisions of this Section 4.06 shall be in full
         force and effect;

                  (ii)     the Note Registrar, the Indenture Trustee, the Paying
         Agent and the Securities Administrator shall be entitled to deal with
         the Depository for all purposes of this Indenture (including the
         payment of principal of and interest on the Notes and the giving of
         instructions or directions hereunder) as the sole holder of the Notes,
         and shall have no obligation to the Beneficial Owners of the Notes;

                  (iii)    to the extent that the provisions of this Section
         4.06 conflict with any other provisions of this Indenture, the
         provisions of this Section 4.06 shall control;

                  (iv)     the rights of Beneficial Owners shall be exercised
         only through the Depository and shall be limited to those established
         by law and agreements between such Owners of Notes and the Depository
         and/or the Depository Participants. Unless and until Definitive Notes
         are issued pursuant to Section 4.08, the initial Depository will make
         book-entry transfers among the Depository Participants and receive and
         transmit payments of principal of and interest on the Notes to such
         Depository Participants; and

                  (v)      whenever this Indenture requires or permits actions
         to be taken based upon instructions or directions of Holders of Notes
         evidencing a specified percentage of the Note Principal Balances of the
         Notes, the Depository shall be deemed to represent such percentage with
         respect to the Notes only to the extent that it has received
         instructions to such effect from Beneficial Owners and/or Depository
         Participants owning or representing, respectively, such required
         percentage of the beneficial interest in the Notes and has delivered
         such instructions to the Securities Administrator and the Indenture
         Trustee, as required by this Indenture.

         Section 4.07 NOTICES TO DEPOSITORY. Whenever a notice or other
communication to the Note Holders is required under this Indenture, unless and
until Definitive Notes shall have been issued to Beneficial Owners pursuant to
Section 4.08, the Indenture Trustee or Securities Administrator, as applicable,
shall give all such notices and communications specified herein to be given to
Holders of the Notes to the Depository, and shall have no obligation to the
Beneficial Owners.

         Section 4.08 DEFINITIVE NOTES. If (i) the Depositor advises the
Securities Administrator in writing that the Depository is no longer willing or
able to properly discharge its responsibilities with respect to the Book-Entry
Notes and the Depositor is unable to locate a qualified successor within 30 days
or (ii) the Depositor, at its option (with the consent of the Securities
Administrator, such consent not to be unreasonably withheld) elects to terminate
the book-entry system through the Depository, then the Securities Administrator
shall request that the Depository notify all Beneficial Owners of the occurrence
of any such event and of the availability of Definitive Notes to Beneficial
Owners requesting the same. Upon surrender to the Securities Administrator of
the typewritten Notes representing the Book-Entry Notes by the Depository,
accompanied by registration instructions, the Issuer shall execute and the
Securities Administrator shall authenticate the Definitive Notes in accordance
with the instructions of the Depository. None of the Issuer, the Note Registrar
or the Securities Administrator shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be


                                       25
<PAGE>


protected in relying on, such instructions. Upon the issuance of Definitive
Notes, the Securities Administrator shall recognize the Holders of the
Definitive Notes as Noteholders.

         In addition, if an Event of Default has occurred and is continuing,
each Note Owner materially adversely affected thereby may at its option request
a Definitive Note evidencing such Noteholder's interest in the related Class of
Notes. In order to make such request, such Noteholder shall, subject to the
rules and procedures of the Depository, provide the Depository or the related
Depository Participant with directions for the Securities Administrator to
exchange or cause the exchange of the Noteholder's interest in such Class of
Notes for an equivalent interest in fully registered definitive form. Upon
receipt by the Securities Administrator of instructions from the Depository
directing the Securities Administrator to effect such exchange (such
instructions to contain information regarding the Class of Notes and the Note
Principal Balance being exchanged, the Depository Participant account to be
debited with the decrease, the registered holder of and delivery instructions
for the Definitive Note, and any other information reasonably required by the
Securities Administrator), (i) the Securities Administrator shall instruct the
Depository to reduce the related Depository Participant's account by the
aggregate Note Principal Balance of the Definitive Note, (ii) the Securities
Administrator shall execute, authenticate and deliver, in accordance with the
registration and delivery instructions provided by the Depository, a Definitive
Note evidencing such Noteholder's interest in such Class of Notes and (iii) the
Securities Administrator shall execute and authenticate a new Book-Entry Note
reflecting the reduction in the Note Principal Balance of such Class of Notes by
the amount of the Definitive Notes.

         Section 4.09 TAX TREATMENT. The Issuer has entered into this Indenture,
and the Notes will be issued with the intention that, for federal, state and
local income, single business and franchise tax purposes, the Notes will qualify
as indebtedness. The Issuer and the Securities Administrator (in accordance with
Section 6.06 hereof), by entering into this Indenture, and each Noteholder, by
its acceptance of its Note (and each Beneficial Owner by its acceptance of an
interest in the applicable Book-Entry Note), agree to treat the Notes for
federal, state and local income, single business and franchise tax purposes as
indebtedness. The Issuer shall be a "U.S. person" (as that term is used in
section 1.1441-4(a)(3)(ii) of United States Treasury Regulations) for United
States federal income tax purposes.

         Section 4.10 SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture
shall cease to be of further effect with respect to the Notes except as to (i)
rights of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments
of principal thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09,
3.17, 3.19 and 3.20, (v) the rights, obligations (to the extent applicable to
the provisions of the Indenture remaining in effect) and immunities of the
Indenture Trustee and Securities Administrator hereunder (including the rights
of the Indenture Trustee and Securities Administrator under Section 6.07 and the
obligations of the Securities Administrator under Section 4.11), and (vi) the
rights of Noteholders as beneficiaries hereof with respect to the property so
deposited with the Indenture Trustee payable to all or any of them, and the
Indenture Trustee, on demand of and at the expense of the Issuer, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to the Notes and shall release and deliver, or cause the Custodian
to deliver, the Collateral to or upon the order of the Issuer, when:


                                       26
<PAGE>


                  (A)      either:

                  (1)      all Notes theretofore authenticated and delivered

         have been replaced or paid as provided in Section 4.03 hereof and (ii)
         Notes for whose payment money has theretofore been deposited in trust
         or segregated and held in trust by the Issuer and thereafter repaid to
         the Issuer or discharged from such trust, as provided in Section 3.03)
         have been delivered to the Securities Administrator for cancellation;
         or

                  (2)      all Notes not theretofore delivered to the Securities
         Administrator for cancellation

                           a.       have become due and payable,

                           b.       will become due and payable at the Final
                                    Scheduled Payment Date within one year, or

                           c.       have been called for early redemption and
                                    the Trust has been terminated pursuant to
                                    Section 8.07 hereof,

         and the Issuer, in the case of (2)a. or (2)b. above, has irrevocably
         deposited or caused to be irrevocably deposited with the Securities
         Administrator, cash or direct obligations of or obligations guaranteed
         by the United States of America (which will mature prior to the date
         such amounts are payable), in trust for such purpose, in an amount
         sufficient to pay and discharge the entire indebtedness on such Notes
         then outstanding not theretofore delivered to the Securities
         Administrator for cancellation when due on the Final Scheduled Payment
         Date or other final Payment Date and has delivered to the Securities
         Administrator and the Indenture Trustee a verification report from a
         nationally recognized accounting firm certifying that the amounts
         deposited with the Securities Administrator are sufficient to pay and
         discharge the entire indebtedness of such Notes, or, in the case of
         (2)c. above, the Issuer shall have complied with all requirements of
         Section 8.07 hereof,

                           (B)      the Issuer has paid or caused to be paid all
         other sums payable hereunder; and

                           (C)      the Issuer has delivered to the Indenture
         Trustee an Officer's Certificate and an Opinion of Counsel, each
         meeting the applicable requirements of Section 10.01 hereof, each
         stating that all conditions precedent herein provided for relating to
         the satisfaction and discharge of this Indenture have been complied
         with and, if the Opinion of Counsel relates to a deposit made in
         connection with Section 4.10(A)(2)b. above, such opinion shall further
         be to the effect that such deposit will constitute an "in-substance
         defeasance" within the meaning of Revenue Ruling 85-42, 1985-1 C.B. 36,
         and in accordance therewith, the Issuer will be the owner of the assets
         deposited in trust for federal income tax purposes.

         Section 4.11 APPLICATION OF TRUST MONEY. All monies deposited with the
Securities Administrator pursuant to Section 4.10 hereof shall be held in trust

<PAGE>


accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent or the Issuer, Certificate Paying
Agent as designee of the Issuer, as the Securities Administrator may determine,
to the Holders of Securities, of all sums due and to become due thereon for
principal and interest or otherwise; but such monies need not be segregated from
other funds except to the extent required herein or required by law.

         Section 4.12 [RESERVED].

         Section 4.13 REPAYMENT OF MONIES HELD BY PAYING AGENT. In connection
with the satisfaction and discharge of this Indenture with respect to the Notes,
all monies then held by any Person other than the Securities Administrator under
the provisions of this Indenture with respect to such Notes shall, upon demand
of the Issuer, be paid to the Securities Administrator to be held and applied
according to Section 3.05 and thereupon such Person shall be released from all
further liability with respect to such monies.

         Section 4.14 TEMPORARY NOTES. Pending the preparation of any Definitive
Notes, the Issuer may execute and upon its written direction, the Securities
Administrator may authenticate and make available for delivery, temporary Notes
that are printed, lithographed, typewritten, photocopied or otherwise produced,
in any denomination, substantially of the tenor of the Definitive Notes in lieu
of which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Notes may
determine, as evidenced by their execution of such Notes.

         If temporary Notes are issued, the Issuer will cause Definitive Notes
to be prepared without unreasonable delay. After the preparation of the
Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes
upon surrender of the temporary Notes at the Corporate Trust Office of the
Securities Administrator, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes, the Issuer shall execute and
the Securities Administrator shall authenticate and make available for delivery,
in exchange therefor, Definitive Notes of authorized denominations and of like
tenor, class and aggregate principal amount. Until so exchanged, such temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as Definitive Notes.

         Section 4.15 REPRESENTATION REGARDING ERISA. By acquiring a Note or
interest therein, each Holder of such Note or Beneficial Owner of any such
interest shall be deemed to represent that either (1) it is not acquiring the
Note with Plan Assets or (2) (A) the acquisition, holding and transfer of such
Note will not give rise to a nonexempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code and (B) the Notes are rated investment
grade or better and such person believes that the Notes are properly treated as
indebtedness without substantial equity features for purposes of the Department
of Labor regulation 29 C.F.R. ss. 2510.3-101, and agrees to so treat the Notes.
Alternatively, regardless of the rating of the Notes, such person may provide
the Securities Administrator and the Owner Trustee with an Opinion of Counsel,
which Opinion of Counsel will not be at the expense of the Issuer, the
Depositor, the Seller, any Underwriter, the Owner Trustee, the Indenture
Trustee, the Securities Administrator, the Master Servicer or the Servicer which
opines that the acquisition, holding and transfer of such Note or interest
therein is permissible under applicable law, will not constitute or result in a
non-exempt prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the Issuer,


                                       28

the Seller, the Depositor, any Underwriter, the Owner Trustee, the Indenture
Trustee, the Securities Administrator, the Master Servicer or the Servicer to
any obligation in addition to those undertaken in the Indenture and the other
Basic Documents.

                              Default and Remedies

         Section 5.01 EVENTS OF DEFAULT. The Issuer shall deliver to the
Indenture Trustee, within five days after learning of the occurrence of an Event
of Default, written notice in the form of an Officer's Certificate of any event
which with the giving of notice and the lapse of time would become an Event of
Default under clause (iii), (iv) or (v) of the definition of "Event of Default",
its status and what action the Issuer is taking or proposes to take with respect
thereto. The Indenture Trustee shall not be deemed to have knowledge of any
Event of Default unless a Responsible Officer has actual knowledge thereof or
unless written notice of such Event of Default is received by a Responsible
Officer and such notice references the Notes, the Trust Estate or this
Indenture.

         Section 5.02 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee at the written direction of the Holders of Notes representing
not less than a majority of the aggregate Note Principal Balance of the Notes
may declare the Notes to be immediately due and payable, by a notice in writing
to the Issuer (and to the Indenture Trustee if such notice is given by
Noteholders), and upon any such declaration the unpaid Note Principal Balance of
the Notes, together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable.

         At any time after such declaration of acceleration of maturity with
respect to an Event of Default has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as
hereinafter in this Article V provided, Holders of the Notes representing not
less than a majority of the aggregate Note Principal Balance of the Notes, by
written notice to the Issuer and the Indenture Trustee, may, subject to Section
5.12, waive the related Event of Default and rescind and annul such declaration
and its consequences if:

                           (i)      the Issuer has paid or deposited with the
         Indenture Trustee or Securities Administrator a sum sufficient to pay:

                                    (A)      all payments of principal of and
                           interest on the Notes and all other amounts that
                           would then be due hereunder or upon the Notes if the
                           Event of Default giving rise to such acceleration had
                           not occurred;

                                    (B)      all sums paid or advanced by the
                           Indenture Trustee hereunder and the reasonable
                           compensation, expenses, disbursements and advances of
                           the Indenture Trustee and its agents and counsel; and

                                    (C)      all Events of Default, other than
                           the nonpayment of the principal of the Notes that has
                           become due solely by such acceleration, have been
                           cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent default or impair any right
consequent thereto.

         Section 5.03 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
INDENTURE TRUSTEE.

         (a)      The Issuer covenants that if (i) default is made in the
payment of any interest on any Note when the same becomes due and payable, and
such default continues for a period of five days, or (ii) default is made in the
payment of the principal of or any installment of the principal of any Note when
the same becomes due and payable, the Issuer shall, upon demand of the Indenture
Trustee, acting at the direction of the Holders of a majority of the aggregate
Note Principal Balances of the Notes, pay to the Securities Administrator, for
the benefit of the Holders of Notes, the whole amount then due and payable on
the Notes for principal and interest, with interest at the applicable Note
Interest Rate upon the overdue principal, and in addition thereto such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Indenture Trustee and its agents and counsel.

         (b)      In case the Issuer shall fail forthwith to pay such amounts
upon such demand, the Indenture Trustee, in its own name and as trustee of an
express trust, subject to the provisions of Section 10.16 hereof may institute a
Proceeding for the collection of the sums so due and unpaid, and may prosecute
such Proceeding to judgment or final decree, and may enforce the same against
the Issuer or other obligor upon the Notes and collect in the manner provided by
law out of the property of the Issuer or other obligor the Notes, wherever
situated, the monies adjudged or decreed to be payable.

         (c)      If an Event of Default occurs and is continuing, the Indenture
Trustee, subject to the provisions of Section 10.16 hereof may, as more
particularly provided in Section 5.04 hereof, in its discretion, proceed to
protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings, as directed in writing by Holders of a majority of the
aggregate Note Principal Balances of the Notes, to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy or legal or equitable right vested in the
Indenture Trustee by this Indenture or by law.

         (d)      In case there shall be pending, relative to the Issuer or any
other obligor upon the Notes or any Person having or claiming an ownership
interest in the Trust Estate, Proceedings under Title 11 of the United States
Code or any other applicable federal or state bankruptcy, insolvency or other
similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial Proceedings
relative to the Issuer or other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Indenture Trustee, as directed
in writing by Holders of a majority of the aggregate Note Principal Balances of
the Notes, irrespective of whether the principal of any Notes shall then be due
and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Indenture Trustee shall have made any demand pursuant to the
provisions of this Section, shall be entitled and empowered, by intervention in
such Proceedings or otherwise:


                                       31
<PAGE>


                  (i)      to file and prove a claim or claims for the whole
         amount of principal and interest owing and unpaid in respect of the
         Notes and to file such other papers or documents as may be necessary or
         advisable in order to have the claims of the Indenture Trustee
         (including any claim for reasonable compensation to the Indenture
         Trustee and each predecessor Indenture Trustee, and their respective
         agents, attorneys and counsel, and for reimbursement of all expenses
         and liabilities incurred, and all advances made, by the Indenture
         Trustee and each predecessor Indenture Trustee, except as a result of
         negligence or bad faith) and of the Noteholders allowed in such
         Proceedings;

                  (ii)     unless prohibited by applicable law and regulations,
         to vote on behalf of the Holders of Notes in any election of a trustee,
         a standby trustee or Person performing similar functions in any such
         Proceedings;

                  (iii)    to collect and receive any monies or other property
         payable or deliverable on any such claims and to distribute all amounts
         received with respect to the claims of the Noteholders and of the
         Indenture Trustee on their behalf, and

                  (iv)     to file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of the Indenture Trustee or the Holders of Notes allowed in any
         judicial proceedings relative to the Issuer, its creditors and its
         property;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Noteholders to make
payments to the Securities Administrator and, in the event that the Indenture
Trustee shall consent to the making of payments directly to such Noteholders, to
pay to the Indenture Trustee such amounts as shall be sufficient to cover
reasonable compensation to the Indenture Trustee, each predecessor Indenture
Trustee and their respective agents, attorneys and counsel, and all other
expenses and liabilities incurred, and all advances made, by the Indenture
Trustee and each predecessor Indenture Trustee.

         (e)      Nothing herein contained shall be deemed to authorize the
Indenture Trustee to authorize or consent to or vote for or accept or adopt on
behalf of any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder in any such proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar Person.

         (f)      All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by the Indenture Trustee
without the possession of any of the Notes or the production thereof in any
trial or other Proceedings relative thereto, and any such action or proceedings
instituted by the Indenture Trustee shall be brought in its own name as trustee
of an express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Indenture Trustee, each
predecessor Indenture Trustee and their respective agents and attorneys, shall
be for the ratable benefit of the Holders of the Notes, subject to Section 5.05
hereof.


                                       32

         (g)      In any Proceedings brought by the Indenture Trustee (and also
any Proceedings involving the interpretation of any provision of this Indenture
to which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all the Holders of the Notes, and it shall not be necessary to
make any Noteholder a party to any such Proceedings.

         Section 5.04 REMEDIES; PRIORITIES. (a) If an Event of Default shall
have occurred and be continuing and if an acceleration has been declared and not
rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the
provisions of Section 10.16 hereof may, and shall, at the written direction of
the Holders of a majority of the aggregate Note Principal Balances of the Notes
(subject to Section 6.02(k)) do one or more of the following (subject to Section
5.05 hereof):

                  (i)      institute Proceedings in its own name and as trustee
         of an express trust for the collection of all amounts then payable on
         the Notes or under this Indenture with respect thereto, whether by
         declaration or otherwise, enforce any judgment obtained and collect
         from the Issuer and any other obligor upon such Notes monies adjudged
         due;

                  (ii)     institute Proceedings from time to time for the
         complete or partial foreclosure of this Indenture with respect to the
         Trust Estate;

                  (iii)    exercise any remedies of a secured party under the
         UCC and take any other appropriate action to protect and enforce the
         rights and remedies of the Indenture Trustee and the Holders of the
         Notes; and

                  (iv)     sell the Trust Estate or any portion thereof or
         rights or interest therein, at one or more public or private sales
         called and conducted in any manner permitted by law;

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate following an Event of Default, unless (A) the
Indenture Trustee obtains the consent of the Holders of 100% of the aggregate
Note Principal Balance of the Notes, (B) the proceeds of such sale or
liquidation distributable to the Holders of the Notes are sufficient to
discharge in full all amounts then due and unpaid upon such Notes for principal
and interest or (C) the Indenture Trustee determines that the Mortgage Loans
will not continue to provide sufficient funds for the payment of principal of
and interest on the applicable Notes as they would have become due if the Notes
had not been declared due and payable, and the Indenture Trustee obtains the
consent of Holders of 66-2/3% of the aggregate Note Principal Balance of the
Notes. In determining such sufficiency or insufficiency with respect to clause
(B) and (C), the Indenture Trustee may, but need not, obtain and rely upon an
opinion (obtained at the expense of the Trust) of an Independent investment
banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Trust Estate for such purpose.
Notwithstanding the foregoing, so long as an "Event of Default" under the
MortgageIT Servicing Agreement has not occurred, any Sale of the Trust Estate
shall be made subject to the continued servicing of the Mortgage Loans by the
Servicer as provided in the MortgageIT Servicing Agreement.

         The Securities Administrator may fix a record date and Payment Date for
any payment to Noteholders pursuant to this Section 5.04. At least 15 days
before such record date, the Securities Administrator shall mail to each
Noteholder a notice that states the record date, the Payment Date and the amount
to be paid.

         Section 5.05 OPTIONAL PRESERVATION OF THE TRUST ESTATE. If the Notes
have been declared to be due and payable under Section 5.02 following an Event
of Default and such declaration and its consequences have not been rescinded and
annulled, the Indenture Trustee may elect to take and maintain possession of the
Trust Estate. It is the desire of the parties hereto and the Noteholders that
there be at all times sufficient funds for the payment of principal of and
interest on the Notes and other obligations of the Issuer and, the Indenture
Trustee shall take such desire into account when determining whether or not to
take and maintain possession of the Trust Estate. In determining whether to take
and maintain possession of the Trust Estate, the Indenture Trustee may, but need
not, obtain and rely upon an opinion of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Trust Estate for such purpose.

         Section 5.06 LIMITATION OF SUITS. No Holder of any Note shall have any
right to institute any Proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless and subject to the provisions of Section 10.16 hereof

                  (i)      such Holder has previously given written notice to
         the Indenture Trustee of a continuing Event of Default;

                  (ii)     the Holders of not less than 25% of the aggregate
         Note Principal Balances of the Notes have made a written request to the
         Indenture Trustee to institute such Proceeding in respect of such Event
         of Default in its own name as Indenture Trustee hereunder;

                  (iii)    such Holder or Holders have offered to the Indenture
         Trustee indemnity reasonably satisfactory to it against the costs,
         expenses and liabilities to be incurred in complying with such request;

                  (iv)     the Indenture Trustee for 60 days after its receipt
         of such notice of request and offer of indemnity has failed to
         institute such Proceedings; and

                  (v)      no direction inconsistent with such written request
         has been given to the Indenture Trustee during such 60-day period by
         the Holders of a majority of the Note Principal Balances of the Notes.

It is understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this Indenture, except in the
manner herein provided.

         Subject to the last paragraph of Section 5.11 herein, in the event the
Indenture Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Holders of Notes, each representing less
than a majority of the Note Principal Balances of the Notes, the Indenture
Trustee shall take such action as requested by the Holders representing the
highest amount (in the aggregate) of Note Principal Balances notwithstanding any
other provisions of this Indenture.

         Section 5.07 UNCONDITIONAL RIGHTS OF NOTEHOLDERS TO RECEIVE PRINCIPAL
AND INTEREST. Notwithstanding any other provisions in this Indenture, the Holder
of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on, if any, such Note on or
after the respective due dates thereof expressed in such Note or in this
Indenture and to institute suit for the enforcement of any such payment, and
such right shall not be impaired without the consent of such Holder.

         Section 5.08 RESTORATION OF RIGHTS AND REMEDIES. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined adversely to the Indenture
Trustee or to such Noteholder, then and in every such case the Issuer, the
Indenture Trustee and the Noteholders shall, subject to any determination in
such Proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Indenture
Trustee and the Noteholders shall continue as though no such Proceeding had been
instituted.

         Section 5.09 RIGHTS AND REMEDIES CUMULATIVE. No right or remedy herein
conferred upon or reserved to the Indenture Trustee or to the Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         Section 5.10 DELAY OR OMISSION NOT A WAIVER. No delay or omission of
the Indenture Trustee or any Holder of any Note to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article V or by law to the Indenture
Trustee or to the Noteholders may be exercised from time to time, and as often
as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as
the case may be.

         Section 5.11 CONTROL BY NOTEHOLDERS. The Holders of a majority of the
aggregate Note Principal Balances of Notes shall have the right to direct the
time, method and place of conducting any Proceeding for any remedy available to
the Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on the Indenture Trustee (subject to the Indenture Trustee's right to
receive indemnity, as provided herein); provided that:

                  (i)      such direction shall not be in conflict with any rule
         of law or with this Indenture;


                                       36
<PAGE>


                  (ii)     any direction to the Indenture Trustee to sell or
         liquidate the Trust Estate shall be by Holders of Notes representing
         not less than 100% of the Note Principal Balances of the Notes; and

                  (iii)    the Indenture Trustee may take any other action
         deemed proper by the Indenture Trustee that is not inconsistent with
         such direction of the Holders of Notes representing a majority of the
         Note Principal Balances of the Notes.

Notwithstanding the rights of Noteholders set forth in this Section 5.11 the
Indenture Trustee need not take any action that it deems unduly prejudicial to
any Noteholder or that it determines might subject it to liability.

         Section 5.12 WAIVER OF PAST DEFAULTS. Prior to the declaration of the
acceleration of the maturity of the Notes as provided in Section 5.02 hereof,
the Holders of Notes representing not less than a majority of the aggregate Note
Principal Balance of the Notes may waive any past Event of Default and its
consequences except an Event of Default (a) with respect to payment of principal
of or interest on any of the Notes or (b) in respect of a covenant or provision
hereof which cannot be modified or amended without the consent of the Holder of
each Note. In the case of any such waiver, the Issuer, the Indenture Trustee and
the Holders of the Notes shall be restored to their former positions and rights
hereunder, respectively, but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereto.

         Upon any such waiver, any Event of Default arising therefrom shall be
deemed to have been cured and not to have occurred, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Event of
Default or impair any right consequent thereto.

         Section 5.13 UNDERTAKING FOR COSTS. All parties to this Indenture
agree, and each Holder of any Note and each Beneficial Owner of any interest
therein by such Holder's or Beneficial Owner's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.13 shall not apply to (a) any suit instituted by
the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the Note
Principal Balances of the Notes or (c) any suit instituted by any Noteholder for
the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note and in this Indenture.

         Section 5.14 WAIVER OF STAY OR EXTENSION LAWS. The Issuer covenants (to
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead or in any manner whatsoever, claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this Indenture; and
the Issuer (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it shall not
hinder, delay or


                                       37
<PAGE>


impede the execution of any power herein granted to the Indenture Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

         Section 5.15 SALE OF TRUST ESTATE. (a) The power to effect any sale or
other disposition (a "Sale") of any portion of the Trust Estate pursuant to
Section 5.04 hereof is expressly subject to the provisions of Section 5.05
hereof and this Section 5.15. The power to effect any such Sale shall not be
exhausted by any one or more Sales as to any portion of the Trust Estate
remaining unsold, but shall continue unimpaired until the entire Trust Estate
shall have been sold or all amounts payable on the Notes and under this
Indenture shall have been paid. The Indenture Trustee may from time to time
postpone any public Sale by public announcement made at the time and place of
such Sale. The Indenture Trustee hereby expressly waives its right to any amount
fixed by law as compensation for any Sale.

         (b)      The Indenture Trustee shall not in any private Sale sell the
Trust Estate, or any portion thereof, unless

                  (1)      the Holders of all Notes consent to or direct the
         Indenture Trustee to make, such Sale, or

                  (2)      the proceeds of such Sale would be not less than the
         entire amount which would be payable to the Noteholders under the
         Notes, in full payment thereof in accordance with Section 5.02 hereof,
         on the Payment Date next succeeding the date of such Sale, or

                  (3)      the Indenture Trustee determines that the conditions
         for retention of the Trust Estate set forth in Section 5.05 hereof
         cannot be satisfied (in making any such determination under clauses (2)
         or (3) of this Section 5.15(b), the Indenture Trustee may rely upon an
         opinion of an Independent investment banking firm obtained and
         delivered as provided in Section 5.05 hereof) and the Holders of Notes
         representing at least 66-2/3% of the Note Principal Balances of the
         Notes consent to such Sale.

The purchase by the Indenture Trustee of all or any portion of the Trust Estate
at a private Sale shall not be deemed a Sale or other disposition thereof for
purposes of this Section 5.15(b).

         (c)      Unless the Holders representing at least 66-2/3% of the Note
Principal Balances of the Notes have otherwise consented or directed the
Indenture Trustee, at any public Sale of all or any portion of the Trust Estate
at which a minimum bid equal to or greater than the amount described in
paragraph (2) of subsection (b) of this Section 5.15 has not been established by
the Indenture Trustee and no Person bids an amount equal to or greater than such
amount, the Indenture Trustee, acting in its capacity as Indenture Trustee on
behalf of the Noteholders, shall bid an amount (which shall include the
Indenture Trustee's right, in its capacity as Indenture Trustee, to credit bid)
at least $1.00 more than the highest other bid in order to preserve the Trust
Estate on behalf of the Noteholders; provided, sufficient funds are in the Trust
Estate to make such bid.

         (d)      In connection with a Sale of all or any portion of the Trust
Estate,


                                       38
<PAGE>


                  (1)      any Holder or Holders of Notes may bid for and
         purchase the property offered for sale, and upon compliance with the
         terms of sale may hold, retain and possess and dispose of such
         property, without further accountability, and may, in paying the
         purchase money therefor, deliver any Notes or claims for interest
         thereon in lieu of cash up to the amount which shall, upon distribution
         of the net proceeds of such sale, be payable thereon, and such Notes,
         in case the amounts so payable thereon shall be less than the amount
         due thereon, shall be returned to the Holders thereof after being
         appropriately stamped to show such partial payment;

                  (2)      the Indenture Trustee, may bid for and acquire the
         property offered for Sale in connection with any Sale thereof, and,
         subject to any requirements of, and to the extent permitted by,
         applicable law in connection therewith, may purchase all or any portion
         of the Trust Estate in a private sale, and, in lieu of paying cash
         therefor, may make settlement for the purchase price by crediting the
         gross Sale price against the sum of (A) the amount which would be
         distributable to the Holders of the Notes and Holders of Certificates
         as a result of such sale on the Payment Date next succeeding the date
         of such Sale and (B) the expenses of the Sale and of any Proceedings in
         connection therewith which are reimbursable to it, without being
         required to produce the Notes in order to complete any such Sale or in
         order for the net Sale price to be credited against such Notes, and any
         property so acquired by the Indenture Trustee shall be held and dealt
         with by it in accordance with the provisions of this Indenture;

                  (3)      the Indenture Trustee shall execute and deliver an
         appropriate instrument of conveyance, prepared by the Issuer and
         satisfactory to the Indenture Trustee, transferring its interest in any
         portion of the Trust Estate in connection with a Sale thereof;

                  (4)      the Indenture Trustee is hereby irrevocably appointed
         the agent and attorney-in-fact of the Issuer to transfer and convey its
         interest in any portion of the Trust Estate in connection with a Sale
         thereof, and to take all action necessary to effect such Sale; and

                  (5)      no purchaser or transferee at such a Sale shall be
         bound to ascertain the Indenture Trustee's authority, inquire into the
         satisfaction of any conditions precedent or see to the application of
         any monies.

         Section 5.16 ACTION ON NOTES. The Indenture Trustee's right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Trust Estate or upon any
of the assets of the Issuer. Any money or property collected by the Indenture
Trustee or the Securities Administrator shall be applied by the Securities
Administrator upon receipt in accordance with Section 5.04(b) hereof.

         Section 5.17 PERFORMANCE AND ENFORCEMENT OF CERTAIN OBLIGATIONS. (a)
Promptly following a request from the Indenture Trustee to do so, the Issuer in
its capacity as holder of the Mortgage Loans, shall take all such lawful action

                                   ARTICLE VI

               The Indenture Trustee and Securities Administrator

         Section 6.01 DUTIES OF INDENTURE TRUSTEE AND SECURITIES ADMINISTRATOR.
(a) If an Event of Default of which the Indenture Trustee has actual knowledge
or has received written notice has occurred and is continuing, the Indenture
Trustee shall exercise the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

         (b)      Except during the continuance of an Event of Default of which
the Indenture Trustee has actual knowledge or has received written notice, in
the case of the Indenture Trustee and, at any time, in the case of the
Securities Administrator:

                  (i)      the Indenture Trustee and the Securities
         Administrator undertake to perform such duties and only such duties as
         are specifically set forth in this Indenture and the other Basic
         Documents to which it is a party and no implied covenants or
         obligations shall be read into this Indenture and the other Basic
         Documents against the Indenture Trustee or the Securities
         Administrator; and

                  (ii)     in the absence of bad faith on its part, the
         Indenture Trustee and the Securities Administrator may each
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to each of the Indenture Trustee and the Securities
         Administrator and conforming to the requirements of this Indenture;
         however, the Indenture Trustee and the Securities Administrator shall
         each examine the certificates and opinions to determine whether or not
         they conform on their face to the requirements of this Indenture.

         (c)      The Indenture Trustee and the Securities Administrator may not
be relieved from liability for each of its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

                  (i)      this paragraph does not limit the effect of paragraph
         (b) of this Section 6.01;

                  (ii)     neither the Indenture Trustee nor the Securities
         Administrator shall be liable for any error of judgment made in good
         faith by a Responsible Officer unless it is proved that the Indenture
         Trustee or the Securities Administrator, as applicable, was negligent
         in ascertaining the pertinent facts; and

                  (iii)    neither the Indenture Trustee nor the Securities
         Administrator shall be liable with respect to any action it takes or
         omits to take in good faith in accordance with a direction received by
         it from Noteholders or from the Issuer, which they are entitled to give
         under the Basic Documents.

         (d)      The Indenture Trustee shall not be liable for interest on any
money received by it except as the Indenture Trustee may agree in writing with
the Issuer.


                                       41
<PAGE>


         (e)      Money held in trust by the Indenture Trustee need not be
segregated from other trust funds except to the extent required by law or the
terms of this Indenture, the Sale and Servicing Agreement or the Trust
Agreement.

         (f)      No provision of this Indenture shall require the Indenture
Trustee or the Securities Administrator to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have
reasonable grounds to believe that repayment of such funds or indemnity
satisfactory to it against such risk or liability is not reasonably assured to
it.

         (g)      Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.

         (h)      The Indenture Trustee shall act in accordance with Sections
6.03 and 6.04 of the Sale and Servicing Agreement and shall act as successor to
the Master Servicer or appoint a successor Master Servicer in accordance with
Section 6.02 of the Sale and Servicing Agreement.

         (i)      In order to comply with its duties under the USA Patriot Act
of 2001, the Indenture Trustee shall obtain and verify certain information and
documentation from the other parties to this Indenture including, but not
limited to, each such party's name, address and other identifying information.

         Section 6.02 RIGHTS OF INDENTURE TRUSTEE AND SECURITIES ADMINISTRATOR.
Except as provided in Section 6.01: (a) The Indenture Trustee and the Securities
Administrator may rely on any document believed by it to be genuine and to have
been signed or presented by the proper person. The Indenture Trustee and the
Securities Administrator need not investigate any fact or matter stated in the
document.

         (b)      Before the Indenture Trustee or the Securities Administrator
acts or refrains from acting, it may require an Officer's Certificate or an
Opinion of Counsel. Neither the Indenture Trustee nor the Securities
Administrator shall be liable for any action it takes or omits to take in good
faith in reliance on an Officer's Certificate or Opinion of Counsel.

         (c)      Neither the Indenture Trustee nor the Securities Administrator
shall be liable for any action it takes or omits to take in good faith which it
believes to be authorized or within its rights or powers; provided, however,
that the Indenture Trustee's or Securities Administrator's conduct does not
constitute willful misconduct, negligence or bad faith.

         (d)      The Indenture Trustee or the Securities Administrator may each
consult with counsel, and the advice or Opinion of Counsel (which shall not be
at the expense of the Indenture Trustee or the Securities Administrator) with
respect to legal matters relating to this Indenture and the Notes shall be full
and complete authorization and protection from liability in respect to any
action taken, omitted or suffered by it hereunder in good faith and in
accordance with the advice or opinion of such counsel.

         (e)      For the limited purpose of effecting any action to be
undertaken by each of the Indenture Trustee and the Securities Administrator,
but not specifically as a duty of the Indenture


                                       42
<PAGE>


Trustee or the Securities Administrator in the Indenture, each of the Indenture
Trustee and the Securities Administrator may execute any of the trusts or powers
hereunder or perform any duties hereunder, either directly or by or through
agents, attorneys, custodians or nominees appointed with due care, and shall not
be responsible for any willful misconduct or negligence on the part of any
agent, attorney, custodian or nominee so appointed.

         (f)      The Indenture Trustee or its Affiliates are permitted to
receive additional compensation that could be deemed to be in the Indenture
Trustee's economic self-interest for (i) serving as investment adviser,
administrator, shareholder servicing agent, custodian or sub-custodian with
respect to certain of the Permitted Investments, (ii) using Affiliates to effect
transactions in certain Permitted Investments and (iii) effecting transactions
in certain Permitted Investments. Such compensation shall not be considered an
amount that is reimbursable or payable to the Indenture Trustee (i) pursuant to
Sections 5.04(b) or 6.07 hereunder or (ii) out of Available Funds.

         (g)      Anything in this Indenture to the contrary notwithstanding, in
no event shall the Indenture Trustee or the Securities Administrator be liable
for special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Indenture Trustee or
the Securities Administrator, respectively, has been advised of the likelihood
of such loss or damage and regardless of the form of action.

         (h)      None of the Securities Administrator, the Issuer or the
Indenture Trustee shall be responsible for the acts or omissions of the other,
it being understood that this Indenture shall not be construed to render them
partners, joint venturers or agents of one another.

         (i)      Neither the Indenture Trustee nor the Securities Administrator
shall be required to expend or risk its own funds or otherwise incur financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if there is reasonable ground for believing that
the repayment of such funds or indemnity reasonably satisfactory to it against
such risk or liability is not reasonably assured to it, and none of the
provisions contained in this Indenture shall in any event require the Indenture
Trustee or the Securities Administrator to perform, or be responsible for the
manner of performance of, any of the obligations of the Master Servicer under
the Sale and Servicing Agreement, except during such time, if any, as the
Indenture Trustee shall be the successor to, and be vested with the rights,
duties, powers and privileges of, the Master Servicer in accordance with the
terms of the Sale and Servicing Agreement.

         (j)      Except for those actions that the Indenture Trustee or the
Securities Administrator are required to take hereunder, neither the Indenture
Trustee nor the Securities Administrator shall have any obligation or liability
to take any action or to refrain from taking any action hereunder in the absence
of written direction as provided hereunder.

         (k)      Neither the Indenture Trustee nor the Securities Administrator
shall be under any obligation to exercise any of the trusts or powers vested in
it by this Indenture, other than its obligation to give notices pursuant to this
Indenture, or to institute, conduct or defend any litigation hereunder or in
relation hereto at the request, order or direction of any of the Noteholders
pursuant to the provisions of this Indenture, unless such Noteholders shall have


                                       43
<PAGE>


offered to the Indenture Trustee or the Securities Administrator, as applicable,
reasonable security or indemnity reasonably satisfactory to it against the
costs, expenses and liabilities which may be incurred therein or thereby.
Nothing contained herein shall, however, relieve the Indenture Trustee of the
obligation, upon the occurrence of an Event of Default of which a Responsible
Officer of the Indenture Trustee has actual knowledge (which has not been cured
or waived), to exercise such of the rights and powers vested in it by this
Indenture and to use the same degree of care and skill in their exercise as a
prudent person would exercise under the circumstances in the conduct of his own
affairs.

         (l)      Neither the Indenture Trustee nor the Securities Administrator
shall be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of Notes representing not less than 25%
of the Note Principal Balance of the Notes and provided that the payment within
a reasonable time to the Indenture Trustee or the Securities Administrator, as
applicable, of the costs, expenses or liabilities likely to be incurred by it in
the making of such investigation is, in the opinion of the Indenture Trustee or
the Securities Administrator, as applicable, reasonably assured to the Indenture
Trustee or the Securities Administrator, as applicable, by the security afforded
to it by the terms of this Indenture. The Indenture Trustee or the Securities
Administrator may require indemnity reasonably satisfactory to it against such
expense or liability as a condition to taking any such action. The reasonable
expense of every such examination shall be paid by the Noteholders requesting
the investigation.

         (m)      Should the Indenture Trustee or the Securities Administrator
deem the nature of any action required on its part to be unclear, the Indenture
Trustee or the Securities Administrator, respectively, may require prior to such
action that it be provided by the Depositor with reasonable further
instructions.

         (n)      The right of the Indenture Trustee or the Securities
Administrator to perform any discretionary act enumerated in this Indenture
shall not be construed as a duty, and neither the Indenture Trustee nor the
Securities Administrator shall be accountable for other than its negligence or
willful misconduct in the performance of any such act.

         (o)      Neither the Indenture Trustee nor the Securities Administrator
shall be required to give any bond or surety with respect to the execution of
the trust created hereby or the powers granted hereunder.

         (p)      Neither the Indenture Trustee nor the Securities Administrator
shall have any duty to conduct any affirmative investigation as to the
occurrence of any condition requiring the repurchase of any Mortgage Loan by the
Seller pursuant to this Indenture or the Mortgage Loan Purchase Agreement, as
applicable, or the eligibility of any Mortgage Loan for purposes of this
Indenture.

         (q)      The Indenture Trustee shall not be deemed to have notice or
actual knowledge of any Event of Default unless actually known to a Responsible
Officer of the Indenture Trustee or written notice thereof (making reference to
this Indenture or the Notes) is received by the Indenture Trustee at the
Corporate Trust Office.

Trustee in its individual or any other capacity may become the owner or pledgee

rights it would have if it were not Indenture Trustee, subject to the
requirements of the Trust Indenture Act. Any Note Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Indenture Trustee

         (b)      The Securities Administrator in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with

         Section 6.05 NOTICE OF EVENT OF DEFAULT. Subject to Section 5.01, the
Indenture Trustee shall promptly mail to each Noteholder notice of the Event of
Default after a Responsible Officer of the Indenture Trustee obtains actual
knowledge or written notice of such event, unless such Event of Default shall
have been waived or cured. Except in the case of an Event of Default in payment
of principal of or interest on any Note, the Indenture Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of Noteholders.

         Section 6.06 REPORTS BY INDENTURE TRUSTEE TO HOLDERS AND TAX
ADMINISTRATION. The Securities Administrator shall deliver to each Noteholder
such information as may be required and such other customary information as the

such holder to prepare its federal and state income tax returns.

         The Securities Administrator shall prepare and file (or cause to be
prepared and filed), on behalf of the Owner Trustee, all tax returns (if any)
and information reports, tax elections and such annual or other reports of the
Issuer as are necessary for preparation of tax returns and information reports
as provided in Section 5.03 of the Trust Agreement, including without limitation

all reasonable out-of-pocket expenses, disbursements and advances and the

with any breach of this Agreement or any claim or legal action (including any
pending or threatened claim or legal action) or otherwise incurred or made by
the Indenture Trustee or the Securities Administrator, respectively, in the
administration of the trusts hereunder (including the reasonable compensation,
expenses and disbursements of its counsel) except any such expense, disbursement
or advance as may arise from its own negligence or intentional misconduct or
which is the responsibility of the Noteholders as provided herein. Such
compensation and reimbursement obligation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust.
Additionally, each of the Indenture Trustee and the Securities Administrator and
any director, officer, employee or agent of the Indenture Trustee or the
Securities Administrator shall be indemnified by the Trust and held harmless
against any loss, liability or expense (including reasonable attorney's fees and
expenses) incurred in the administration of this Agreement (other than its
ordinary out of pocket expenses incurred hereunder) or in connection with any
claim or legal action relating to (a) the Basic Documents or (b) the Notes,
other than any loss, liability or expense incurred by reason of its own
negligence or intentional misconduct, or which is the responsibility of the
Noteholders as provided herein. Notwithstanding the foregoing, the Indenture
Trustee and any director, officer, employee or agent of the Indenture Trustee
shall also be indemnified by the Trust and held harmless against any loss,
liability or expense (including reasonable attorney's fees and expenses)
incurred in the administration of the Yield Maintenance Agreement or in
connection with any claim or legal action relating to the Yield Maintenance
Agreement which is the responsibility of the Noteholders as provided herein.
Such indemnity and agreement to hold harmless shall survive the termination of
this Agreement or the resignation or removal of the Indenture Trustee and the
Securities Administrator, as applicable, hereunder.

         The Issuer's payment obligations to the Indenture Trustee and
Securities Administrator pursuant to this Section 6.07 shall survive the
discharge of this Indenture and the termination or resignation of the Indenture
Trustee or Securities Administrator. When the Indenture Trustee or the
Securities Administrator incurs expenses after the occurrence of an Event of
Default with respect to the Issuer, the expenses are intended to constitute
expenses of administration under Title 11 of the United States Code or any other
applicable federal or state bankruptcy, insolvency or similar law.

         Section 6.08 REPLACEMENT OF INDENTURE TRUSTEE AND THE SECURITIES
ADMINISTRATOR. No resignation or removal of the Indenture Trustee or the
Securities Administrator and no appointment of a successor Indenture Trustee or
successor Securities Administrator shall become effective until the acceptance
of appointment by the successor Indenture Trustee or successor Securities
Administrator pursuant to this Section 6.08. The Indenture Trustee or the
Securities Administrator may resign at any time by so notifying the Issuer. Any
resignation or removal of the Securities Administrator shall result in the
automatic removal of the Master Servicer to the extent that Wells Fargo Bank,
N.A. is both the Securities Administrator and Master Servicer. Holders of a
majority of Note Principal Balances of the Notes may remove either of the
Indenture Trustee or the Securities Administrator by so notifying the Indenture
Trustee or the Securities Administrator and may appoint a successor Indenture
Trustee or successor Securities Administrator. The Issuer shall remove the
Indenture Trustee or the Securities Administrator, as applicable, if:


                                       46

                  (i)      the Indenture Trustee or the Securities Administrator

         the Indenture Trustee or the Securities Administrator or its property;
         or

                  (iv)     the Indenture Trustee or the Securities Administrator
         otherwise becomes incapable of acting.

         If the Indenture Trustee or the Securities Administrator resigns or is
removed or if a vacancy exists in the office of the Indenture Trustee or the
Securities Administrator for any reason (the Indenture Trustee or the Securities
Administrator in such event being referred to herein as the retiring Indenture
Trustee or the retiring Securities Administrator), the Issuer shall promptly
appoint a successor Indenture Trustee or successor Securities Administrator.

         Each of a successor Indenture Trustee or successor Securities
Administrator shall deliver a written acceptance of its appointment to the
retiring Indenture Trustee or the retiring Securities Administrator, as
applicable, and to the Issuer. Thereupon, the resignation or removal of the
retiring Indenture Trustee or the retiring Securities Administrator shall become
effective, and the successor Indenture Trustee or successor Securities
Administrator shall have all the rights, powers and duties of the Indenture
Trustee or the Securities Administrator, as applicable, under this Indenture.

mail a notice of its succession to Noteholders. The retiring Indenture Trustee
or the retiring Securities Administrator shall promptly transfer all property
held by it as Indenture Trustee or Securities Administrator, as applicable, to
the successor Indenture Trustee or successor Securities Administrator.

         If a successor Indenture Trustee or successor Securities Administrator
does not take office within 60 days after the retiring Indenture Trustee or the
retiring Securities Administrator, as applicable, resigns or is removed, the
retiring Indenture Trustee or the retiring Securities Administrator, the Issuer
or the Holders of a majority of Note Principal Balances of the Notes may
petition any court of competent jurisdiction for the appointment of a successor
Indenture Trustee or successor Securities Administrator.

         Notwithstanding the replacement of the Indenture Trustee or the
Securities Administrator pursuant to this Section, the Issuer's obligations
under Section 6.07 shall continue for the benefit of the retiring Indenture
Trustee or the retiring Securities Administrator.

         Section 6.09 SUCCESSOR INDENTURE TRUSTEE AND SECURITIES ADMINISTRATOR
BY MERGER. If the Indenture Trustee or the Securities Administrator consolidates
with, merges or converts into, or transfers all or substantially all of its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation, without any
further act, shall be the successor Indenture Trustee or successor Securities
Administrator, as applicable; provided, that such corporation or banking
association shall be otherwise qualified and eligible

this Indenture and any of the Notes shall have been authenticated but not
delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee and deliver such Notes so
authenticated; and if at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is in the Notes or in this Indenture provided
that the certificate of the Indenture Trustee shall have.

         Section 6.10 APPOINTMENT OF CO-INDENTURE TRUSTEE OR SEPARATE INDENTURE
TRUSTEE. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in

Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Trust Estate, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Trust Estate, or any part hereof, and, subject to
the other provisions of this Section, such powers, duties, obligations, rights
and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 6.11 hereof.

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

                  (i)      all rights, powers, duties and obligations conferred
         or imposed upon the Indenture Trustee shall be conferred or imposed
         upon and exercised or performed by the Indenture 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 Indenture 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 Indenture 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 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 Indenture
         Trustee;

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

                  (iii)    the Indenture Trustee may at any time accept the
         resignation of or remove any separate trustee or co-trustee.

         (c)      Any notice, request or other writing given to the Indenture
Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as


                                       48

if given to each of them. Every instrument appointing any separate trustee or
co-trustee shall refer to this Indenture and the conditions of this Article VI.
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 Indenture Trustee or

Indenture, specifically including every provision of this Indenture relating to
the conduct of, affecting the liability of, or affording protection to, the
Indenture Trustee. Every such instrument shall be filed with the Indenture

the Indenture Trustee, its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Indenture 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 Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

under which other securities of the Issuer are outstanding if the requirements
for such exclusion set forth in TIA ss. 310(b)(1) are met.

         Section 6.12 PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUER. The
Indenture Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). An Indenture Trustee who has resigned or
been removed shall be subject to TIA ss. 311(a) to the extent indicated.

provided by the Master Servicer pursuant to Section 3.01 of the Sale and

Indenture and the respective obligations and responsibilities of the Issuer, the
Securities Administrator and the Indenture Trustee created hereby shall

the Court of St. James, living on the date hereof.

         Section 8.05 RELEASE OF TRUST ESTATE. (a) Subject to the payment of its
fees, expenses and indemnities, the Indenture Trustee may, and when required by
the provisions of this Indenture shall, execute instruments prepared by the
Issuer to release property from the lien of this Indenture, or convey the
Indenture Trustee's interest in the same, in a manner and under circumstances

the purposes of any repurchase by the Seller of a Mortgage Loan pursuant to
Section 2.02 of the Sale and Servicing Agreement or any repurchase by the
Servicer of a Mortgage Loan pursuant to Section 3.21 of the Sale and Servicing
Agreement; provided, however, any such conveyance shall be without recourse to
the Indenture Trustee and without any obligation on its part to make any
representations or warranties with respect to such property released from the
lien of this Indenture. No party relying upon an instrument executed by the
Indenture Trustee as provided in


                                       55

Article VIII hereunder shall be bound to ascertain the Indenture Trustee's
authority, inquire into the satisfaction of any conditions precedent, or see to
the application of any monies.

         (b)      The Indenture Trustee shall, at such time as (i) it is
notified by the Securities Administrator that there are no Notes Outstanding and
(ii) all sums due to the Indenture Trustee pursuant to this Indenture have been
paid, release any remaining portion of the Trust Estate that secured the Notes
from the lien of this Indenture.

         (c)      The Indenture Trustee shall release property from the lien of
this Indenture pursuant to this Section 8.05 only upon receipt of a request from
the Issuer which, except in the case of a repurchase of a Mortgage Loan pursuant
to Sections 2.02 or 3.21 of the Sale and Servicing Agreement, shall also be

all applicable requirements have been satisfied and upon receipt of such
certificates required under Section 10.01(b).

         Section 8.06 SURRENDER OF NOTES UPON FINAL PAYMENT. By acceptance of
any Note, the Holder thereof agrees to surrender such Note to the Securities
Administrator promptly, prior to such Noteholder's receipt of the final payment
thereon.

         Section 8.07 OPTIONAL REDEMPTION OF THE NOTES. (a) The Majority
Certificateholder shall have the option to redeem the Notes in whole, but not in
part, 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. The aggregate redemption price for
the Notes will be equal to the unpaid Note Principal Balance of the Notes as of
the Payment Date on which the proposed redemption will take place in accordance
with the foregoing, together with accrued and unpaid interest thereon at the
applicable Note Interest Rate through such Payment Date (including any Basis
Risk Shortfall Carry-Forward Amounts), plus an amount sufficient to pay in full
all amounts owing to the Indenture Trustee, the Master Servicer and the
Securities Administrator pursuant to any Basic Document (which amounts shall be
specified by such Person in writing upon request of the Issuer, the Master
Servicer and the Securities Administrator, as applicable), and any Swap
Termination Payment payable to the Swap Provider as a result of a termination
pursuant to this Section 8.07.

         (b)      In order to exercise the foregoing option, the Majority
Certificateholder shall provide written notice of its exercise of such option to
the Indenture Trustee, the Securities Administrator, the Owner Trustee, the Swap
Provider and the Master Servicer at least 15 days prior to its exercise.
Following receipt of the notice, the Securities Administrator shall provide
notice to the Noteholders of the final payment on the Notes. In addition, the
Majority Certificateholder shall, not less than one Business Day prior to the
proposed Payment Date on which such redemption is to be made, deposit the
aggregate redemption price specified in (a) above with the Securities
Administrator, who shall deposit the aggregate redemption price into the Payment
Account and shall, on the Payment Date after receipt of the funds, apply such
funds to make final payments of principal and interest on the Notes in
accordance with Section 3.05 hereof and payment in full to the Securities
Administrator, the Master Servicer and the Swap Provider, and this Indenture
shall be discharged subject to the provisions of Section 4.10 hereof. If for any
reason the amount deposited by the Majority Certificateholder is not sufficient
to make


                                       56
<PAGE>


such redemption or such redemption cannot be completed for any reason, the
amount so deposited by the Majority Certificateholder with the Securities
Administrator shall be immediately returned to the Majority Certificateholder in
full and shall not be used for any other purpose or be deemed to be part of the
Trust Estate.

         Section 8.08 YIELD MAINTENANCE AGREEMENT. (a) In the event that the
Securities Administrator does not receive by the Business Day preceding a
Payment Date the amount reported to the Securities Administrator as the amount
to be paid with respect to such Payment Date by the Yield Maintenance Provider
under the Yield Maintenance Agreement, the Securities Administrator shall notify
the Indenture Trustee and the Indenture Trustee, at the direction of the Holders
of a majority of the aggregate Note Principal Balances of the Notes in
accordance with Section 5.11, shall enforce the obligation of the Yield
Maintenance Provider under such Yield Maintenance Agreement. The parties hereto
acknowledge that the Yield Maintenance Provider shall make all calculations, and
determine the amounts to be paid, under the Yield Maintenance Agreement. The
Securities Administrator may conclusively rely on such calculations and
determination and any notice received by it from the Yield Maintenance Provider
pursuant to the Yield Maintenance Agreement. The Indenture Trustee may
conclusively rely on information provided to it by the Securities Administrator.
The Indenture Trustee has no obligation to monitor, and no liability for, the
performance of the Securities Administrator under the Yield Maintenance
Agreement, and the Indenture Trustee shall be indemnified by the Trust and held
harmless against any loss, liability or expense incurred in the administration
of the Yield Maintenance Agreement as provided under Section 6.07.

         (b)      The Securities Administrator shall deposit or cause to be
deposited any amount received under the Yield Maintenance Agreement into the
Payment Account on the date such amount is received from the Yield Maintenance
Provider (including termination payments, if any). All payments received under
the Yield Maintenance Agreement shall be distributed as part of Available Funds.

         (c)      Payments made under the Yield Maintenance Agreement shall be
distributed in the following order of priority:

                  (i)      first, to the Holders of the Class 1-A-1 Notes and
         Class 1-A-2 Notes, on a pro rata basis, and then to the Class 1-M-1,
         Class 1-M-2, Class 1-B-1 and Class 1-B-2 Notes, in that order, any
         Basis Risk Shortfall Carry-Forward Amount for such Notes on such
         Payment Date; and

                  (ii)     any remaining amounts will be distributed to the
         Certificate Paying Agent, as designee of the Issuer, for the benefit of
         the Holders of the Trust Certificates.

         Section 8.09 THE SWAP AGREEMENTS.

         (a)      The Securities Administrator shall establish and maintain the
Swap Account as a segregated trust account or accounts. The Swap Account shall
be an Eligible Account. The Securities Administration shall deposit in the Swap
Account any Net Swap Payments and other amounts payable to the Trust and the
Swap Provider under the Swap Agreements. On each Payment Date for which the
Securities Administrator has received a payment under the Swap Agreements, the
Securities Administrator shall pay such amounts in accordance with the
priorities set forth in clauses (b) and (c) of this Section.


                                       57
<PAGE>


         (b)      On each Payment Date, any Net Swap Payments and Swap
Termination Payments (other than Swap Termination Payments resulting from a Swap
Provider Trigger Event) payable by the Trust pursuant to the Swap Agreements
shall be deducted from Group 1 Available Funds prior to any distributions to the
Group 1 Noteholders. On each Distribution Date, such amounts will be distributed
to the Swap Provider, first to make any Net Swap Payment owed to the Swap
Provider pursuant to the Swap Agreements for such Payment Date, and second to
make any Swap Termination Payment (not due to a Swap Provider Trigger Event)
owed to the Swap Provider pursuant to the Swap Agreements for such Payment Date.
Any Swap Termination Payment, triggered by a Swap Provider Trigger Event owed to
the Swap Provider pursuant to the Swap Agreements will be subordinated to
distributions to the Group 1 Noteholders and shall be paid in accordance with
Section 3.05(d).

         (c)      On each Payment Date, any amounts received by the Swap
Provider pursuant to the Swap Agreements shall be distributed in the following
order of priority:

                  (i)      first, concurrently, to each Class of Class 1-A-1
         Notes and Class 1-A-2 Notes, the related Basis Risk Shortfall
         Carry-Forward Amount for such Payment Date, on a pro rata basis based
         on such respective Basis Risk Shortfall Carry-Forward Amounts;

                  (ii)     second, sequentially, to the Class 1-M-1, Class
         1-M-2, Class 1-B-1 and Class 1-B-2 Notes, in that order; and

                  (iii)    third, any remaining amounts payable to the Trust
         under the Swap Agreements shall be included in the Net Monthly Excess
         Cashflow for Loan Group 1 and distributed in accordance with Section
         3.05(d), up to an amount equal to $80,000,000.

         (d)      Notwithstanding anything to the contrary herein, the
Securities Administrator shall only be required to make the payments described
herein to the extent that the Securities Administrator receives the
corresponding payment from the Swap Provider under the Swap Agreement and to the
extent there are sufficient Available Funds from the Trust for payment to the
Swap Provider.

         Section 8.10 RIGHTS OF SWAP PROVIDER.

         The Swap Provider shall be deemed a third-party beneficiary of this
Indenture to the same extent as if it were a party hereto and shall have the
right, upon designation of an "Early Termination Date" (as defined in the Swap
Agreements), to enforce its rights under this Indenture, which rights include
but are not limited to the obligation of the Securities Administrator (A) to pay
any Net Swap Payment required pursuant to Section 8.09 and any Swap Termination
Payment required pursuant to Sections 3.05(d) and 8.09 to the Swap Provider, (B)
to make such deposits to the Payment Account, investments therein and payments
therefrom of any payments under the Swap Account as are required pursuant to
Section 3.01 that are payable to the Swap Provider. For the protection and
enforcement of the provisions of this Section the Swap Provider shall be
entitled to such relief as can be given either at law or in equity.

                             Supplemental Indentures

         Section 9.01 SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.
(a) Without the consent of the Holders of any Notes or the Swap Provider but
with prior notice to the Rating Agency, the Issuer, the Securities Administrator
and the Indenture Trustee, when authorized by an Issuer Request in the case of
the Securities Administrator and the Indenture Trustee, at any time and from
time to time, may enter into one or more indentures supplemental hereto (which
shall conform to the provisions of the TIA as in force at the date of the
execution thereof), in form satisfactory to the Indenture Trustee and the
Securities Administrator, for any of the following purposes:

                  (i)      to correct or amplify the description of any property
         at any time subject to the lien of this Indenture, or better to assure,
         convey and confirm unto the Indenture Trustee any property subject or
         required to be subjected to the lien of this Indenture, or to subject
         to the lien of this Indenture additional property;

                  (ii)     to evidence the succession, in compliance with the
         applicable provisions hereof, of another person to the Issuer, and the
         assumption by any such successor of the covenants of the Issuer herein
         and in the Notes contained;

                  (iii)    to add to the covenants of the Issuer, for the
         benefit of the Holders of the Notes, or to surrender any right or power
         herein conferred upon the Issuer;

                  (iv)     to convey, transfer, assign, mortgage or pledge any
         property to or with the Indenture Trustee;

                  (v)      to cure any ambiguity, to correct or supplement any
         provision herein or in any supplemental indenture that may be
         inconsistent with any other provision herein or in any supplemental
         indenture;

                  (vi)     to make any other provisions with respect to matters
         or questions arising under this Indenture or in any supplemental
         indenture; provided, that such action shall not materially and
         adversely affect the interests of the Holders of the Notes;

                  (vii)    to evidence and provide for the acceptance of the
         appointment hereunder by a successor trustee with respect to the Notes
         and to add to or change any of the provisions of this Indenture as
         shall be necessary to facilitate the administration of the trusts
         hereunder by more than one trustee, pursuant to the requirements of
         Article VI hereof; or

                  (viii)   to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the TIA or under any similar
         federal statute hereafter enacted and to add to this Indenture such
         other provisions as may be expressly required by the TIA;


                                       59
<PAGE>


provided, however, that no such indenture supplements shall be entered into
unless the Indenture Trustee, the Securities Administrator and the Swap Provider
shall have received an Opinion of Counsel not at the expense of the Indenture
Trustee or the Securities Administrator as to the enforceability of any such
indenture supplement against the Issuer and to the effect that (i) such
indenture supplement is authorized or permitted hereunder and will not
materially and adversely affect the Holders of the Notes or the Swap Provider
and (ii) entering into such indenture supplement will not result in a
"significant modification" of the Notes under Treasury Regulation Section
1.1001-3 or adversely affect the status of the Notes as indebtedness for federal
income tax purposes.

         The Indenture Trustee and the Securities Administrator are hereby
authorized to join in the execution of any such supplemental indenture and to
make any further appropriate agreements and stipulations that may be therein
contained.

         (b)      The Issuer, the Securities Administrator and the Indenture
Trustee, when authorized by an Issuer Request in the case of the Securities
Administrator and the Indenture Trustee and the Indenture Trustee, may, also
without the consent of any of the Holders of the Notes or the Swap Provider and
prior notice to the Rating Agency, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or of
modifying in any manner the rights of the Holders of the Notes under this
Indenture; provided, however, that such action as evidenced by an Opinion of
Counsel, (i) is authorized or permitted by this Indenture, and shall not (ii)
adversely affect in any material respect the interests of any Noteholder and
(iii) will not cause the Issuer to be subject to an entity level tax for federal
income tax purposes.

         Section 9.02 SUPPLEMENTAL INDENTURES WITH CONSENT OF NOTEHOLDERS. The
Issuer, the Securities Administrator and the Indenture Trustee, when authorized
by an Issuer Request in the case of the Securities Administrator and the
Indenture Trustee, also may, with prior notice to the Rating Agency and, with
the consent of the Swap Provider and Holders of not less than a majority of the
Note Principal Balance of each Class of Notes affected thereby, by Act (as
defined in Section 10.03 hereof) of such Holders delivered to the Issuer, the
Securities Administrator and the Indenture Trustee, enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to, or
changing in any manner or eliminating any of the provisions of, this Indenture
or of modifying in any manner the rights of the Holders of the Notes under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the Holder of each Note affected thereby:

                  (i)      change the date of payment of any installment of
         principal of or interest on any Note, or reduce the principal amount
         thereof or the interest rate thereon, change the provisions of this
         Indenture relating to the application of collections on, or the
         proceeds of the sale of, the Trust Estate to payment of principal of or
         interest on the Notes, or change any place of payment where, or the
         coin or currency in which, any Note or the interest thereon is payable,
         or impair the right to institute suit for the enforcement of the
         provisions of this Indenture requiring the application of funds
         available therefor, as provided in Article V, to the payment of any
         such amount due on the Notes on or after the respective due dates
         thereof;


                                       60
<PAGE>


                  (ii)     reduce the percentage of the Note Principal Balances
         of the Notes, the consent of the Holders of which is required for any
         such supplemental indenture, or the consent of the Holders of which is
         required for any waiver of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences provided
         for in this Indenture;

                  (iii)    modify or alter the provisions of the proviso to the
         definition of the term "Outstanding" or modify or alter the exception
         in the definition of the term "Holder";

                  (iv)     reduce the percentage of the Note Principal Balances
         of the Notes required to direct the Indenture Trustee to direct the
         Issuer to sell or liquidate the Trust Estate pursuant to Section 5.04
         hereof;

                  (v)      modify any provision of this Section 9.02 except to
         increase any percentage specified herein or to provide that certain
         additional provisions of this Indenture or the Basic Documents cannot
         be modified or waived without the consent of the Holder of each Note
         affected thereby;

                  (vi)     modify any of the provisions of this Indenture in
         such manner as to affect the calculation of the amount of any payment
         of interest or principal due on any Note on any Payment Date (including
         the calculation of any of the individual components of such
         calculation); or

                  (vii)    permit the creation of any lien ranking prior to or
         on a parity with the lien of this Indenture with respect to any part of
         the Trust Estate or, except as otherwise permitted or contemplated
         herein, terminate the lien of this Indenture on any property at any
         time subject hereto or deprive the Holder of any Note of the security
         provided by the lien of this Indenture;

and provided, further, that such action shall not, as evidenced by an Opinion of
Counsel, cause the Issuer to be subject to an entity level tax.

         Any such action shall not adversely affect in any material respect the
interest of any Holder (other than a Holder who shall consent to such
supplemental indenture) as evidenced by an Opinion of Counsel (provided by, and
at the expense of, the Person requesting such supplemental indenture) delivered
to the Indenture Trustee and the Securities Administrator.

         It shall not be necessary for any Act of Noteholders under this Section
9.02 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such Act shall approve the substance thereof.

         Promptly after the execution by the Issuer, the Securities
Administrator and the Indenture Trustee of any supplemental indenture pursuant
to this Section 9.02, the Securities Administrator shall mail to the Holders of
the Notes to which such amendment or supplemental indenture relates a notice
setting forth in general terms the substance of such supplemental indenture. Any
failure of the Securities Administrator to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of the Indenture Trustee, the Securities Administrator, the
Issuer and the Holders of the Notes shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture

for any and all purposes.

such supplemental indenture may be prepared and executed by the Issuer and
authenticated and delivered by the Securities Administrator in exchange for
Outstanding Notes.

                                  Miscellaneous

         Section 10.01 COMPLIANCE CERTIFICATES AND OPINIONS, ETC. (a) Upon any
application or request by the Issuer to the Indenture Trustee or the Securities
Administrator to take any action under any provision of this Indenture, the
Issuer shall furnish to the Indenture Trustee and the Securities Administrator
(i) an Officer's Certificate stating that all conditions precedent, if any,
provided for in this Indenture relating to the proposed action have been
complied with and (ii) an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent, if any, have been complied with, except
that, in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this Indenture,
no additional certificate or opinion need be furnished provided they are
substantially to the same effect.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                  (1)      a statement that each signatory of such certificate
         or opinion has read or has caused to be read such covenant or condition
         and the definitions herein relating thereto;

                  (2)      a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (3)      a statement that, in the opinion of each such
         signatory, such signatory has made such examination or investigation as
         is necessary to enable such signatory to express an informed opinion as
         to whether or not such covenant or condition has been complied with;

                  (4)      a statement as to whether, in the opinion of each
         such signatory, such condition or covenant has been complied with; and

                  (5)      if the signatory of such certificate or opinion is
         required to be Independent, the statement required by the definition of
         the term "Independent Certificate".

         (b)      (i) Prior to the deposit of any Collateral or other property
or securities with the Indenture Trustee that is to be made the basis for the
release of any property or securities subject to the lien of this Indenture, the
Issuer shall, in addition to any obligation imposed in Section 10.01 (a) or
elsewhere in this Indenture, furnish to the Indenture Trustee an Officer's
Certificate certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days prior to such deposit) to the
Issuer of the Collateral or other property or securities to be so deposited and
a report from a nationally recognized accounting firm verifying such value. For
the avoidance of doubt, this Section 10.01(b) does not apply to the substitution
of a Substitute Mortgage Loan for any Deleted Mortgage Loan, any repurchase of
Mortgage Loans or as otherwise set forth in this Indenture.

                  (ii)     Whenever the Issuer is required to furnish to the
         Indenture Trustee an Officer's Certificate certifying or stating the
         opinion of any signer thereof as to the matters described in clause
         (b)(i) above, the Issuer shall also deliver to the Indenture Trustee an
         Independent Certificate from a nationally recognized accounting firm as
         to the same matters, if the fair value of the securities to be so
         deposited and of all other such securities made the basis of any such
         withdrawal or release since the commencement of the then current fiscal
         year of the Issuer, as set forth in the certificates delivered pursuant
         to clause (i) above and this clause (ii), is 10% or more of the Note
         Principal Balances of the Notes, but such a certificate need not be
         furnished with respect to any securities so deposited, if the fair
         value thereof as set forth in the related Officer's Certificate is less
         than $25,000 or less than one percent of the Note Principal Balances of
         the Notes.

                  (iii)    Whenever any property or securities are to be
         released from the lien of this Indenture, the Issuer shall also furnish
         to the Indenture Trustee an Officer's Certificate certifying or stating
         the opinion of each person signing such certificate as to the fair
         value (within 90 days prior to such release) of the property or
         securities proposed to be released and stating that in the opinion of
         such person the proposed release will not impair the security under
         this Indenture in contravention of the provisions hereof.

                  (iv)     Whenever the Issuer is required to furnish to the
         Indenture Trustee an Officer's Certificate certifying or stating the
         opinion of any signer thereof as to the matters described in clause
         (iii) above, the Issuer shall also furnish to the Indenture Trustee an
         Independent Certificate as to the same matters if the fair value of the
         property or securities and of all other property or securities released
         from the lien of this Indenture since the commencement of the
         then-current calendar year, as set forth in the certificates required
         by clause (iii) above and this clause (iv), equals 10% or more of the
         Note Principal Balances of the Notes, but such certificate need not be
         furnished in the case of any release of property or securities if the
         fair value thereof as set forth in the related Officer's Certificate is
         less than $25,000 or less than one percent of the then Note Principal
         Balances of the Notes.

         Section 10.02 FORM OF DOCUMENTS DELIVERED TO INDENTURE TRUSTEE. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

         Any certificate or opinion of an Authorized Officer of the Issuer may
be based, insofar as it relates to legal matters, upon a certificate or opinion
of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Seller or the Issuer, stating that the information with respect to such
factual matters is in the possession of the Seller or the Issuer, unless such


                                       64
<PAGE>


counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article VI.

         Section 10.03 ACTS OF NOTEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders in person or by agents duly appointed in writing; and except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Indenture Trustee, and,
where it is hereby expressly required, to the Issuer. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Noteholders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01 hereof) conclusive in favor of the Indenture
Trustee and the Issuer, if made in the manner provided in this Section 10.03
hereof.

         (b)      The fact and date of the execution by any person of any such
instrument or writing may be proved in any manner that the Indenture Trustee
deems sufficient.

         (c)      The ownership of Notes shall be proved by the Note Registrar.

         (d)      Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Notes shall bind the Holder
of every Note issued upon the registration thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Indenture Trustee or the Issuer in reliance thereon, whether or not notation of
such action is made upon such Note.

         Section 10.04 NOTICES ETC., TO INDENTURE TRUSTEE, SECURITIES
ADMINISTRATOR, ISSUER, SWAP PROVIDER AND RATING AGENCIES. Any request, demand,
authorization, direction, notice, consent, waiver or act of Noteholders or other
documents provided or permitted by this Indenture shall be in writing and if
such request, demand, authorization, direction, notice, consent, waiver or act
of Noteholders is to be made upon, given or furnished to or filed with:

         Trust Services - MortgageIT 2005-1), facsimile no.: (410) 715-2380, or
         such other address as may hereafter be furnished to the other parties
         hereto in writing. The Securities Administrator shall promptly transmit
         any notice received by it from the Noteholders to the Issuer

                  (iii)    the Issuer by the Indenture Trustee or by any
         Noteholder shall be sufficient for every purpose hereunder if in
         writing and mailed first-class, postage prepaid to the Issuer addressed
         to: MortgageIT Trust 2005-1, in care of Wilmington Trust Company,
         Rodney Square North, 1100 North Market Street, Wilmington, Delaware
         19990-0001, Attention: Corporate Trust Administration, or at any other
         address previously furnished in writing to the Indenture Trustee by the
         Issuer. The Issuer shall promptly transmit any notice received by it
         from the Noteholders to the Indenture Trustee.

                  (iv)     The Swap Provider shall be sufficient for every
         purpose hereunder if in writing and mailed first-class, postage prepaid
         addressed to: UBS AG, Stamford Brach, Collateral Management, 677
         Washington Boulevard, Stamford, Connecticut 06901, Attention: General
         Counsel, or at any other address previously furnished in writing to the
         Indenture Trustee by the Swap Provider.

         Notices required to be given to the Rating Agency by the Issuer, the
Indenture Trustee, the Securities Administrator or the Owner Trustee shall be in
writing, mailed first-class postage pre-paid, to, in the case of Standard &
Poor's, at the following address: Standard & Poor's, 55 Water Street, 41st
Floor, New York, New York 10041, Attention of Asset Backed Surveillance
Department, in the case of Moody's, at the following address: Moody's Investors
Service, Inc., 99 Church Street, New York, New York 10007; or at such other
address as shall be designated by written notice to the other parties.

         Section 10.05 NOTICES TO NOTEHOLDERS; WAIVER. Where this Indenture
provides for notice to Noteholders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid to each Noteholder affected by such
event, at such Person's address as it appears on the Note Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given regardless of
whether such notice is in fact actually received.


                                       66
<PAGE>


         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed with the Indenture
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver.

         In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event to Noteholders when such notice is required to be
given pursuant to any provision of this Indenture, then any manner of giving
such notice as shall be satisfactory to the Indenture Trustee shall be deemed to
be a sufficient giving of such notice.

         Where this Indenture provides for notice to the Rating Agencies,
failure to give such notice shall not affect any other rights or obligations
created hereunder, and shall not under any circumstance constitute an Event of
Default.

         Section 10.06 CONFLICT WITH TRUST INDENTURE ACT. If any provision
hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control.

         The provisions of TIA ss.ss. 310 through 317 that impose duties on any
Person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture,
whether or not physically contained herein.

         Section 10.07 EFFECT OF HEADINGS. The Article and Section headings
herein are for convenience only and shall not affect the construction hereof.

         Section 10.08 SUCCESSORS AND ASSIGNS. All covenants and agreements in
this Indenture and the Notes by the Issuer shall bind its successors and
assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind its successors, co-trustees and agents.

         Section 10.09 SEPARABILITY. In case any provision in this Indenture or
in the Notes shall be invalid, illegal or unenforceable, the validity, legality,
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby. Section 10.10 [RESERVED].

         Section 10.11 LEGAL HOLIDAYS. In any case where the date on which any
payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Notes or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

         Section 10.12 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS,


                                       67
<PAGE>


RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

         Section 10.13 COUNTERPARTS. This Indenture may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

         Section 10.14 RECORDING OF INDENTURE. If this Indenture is subject to
recording in any appropriate public recording offices, such recording is to be
effected by the Issuer and at its expense accompanied by an Opinion of Counsel
at its expense (which may be counsel to the Issuer, the Indenture Trustee or any
other counsel reasonably acceptable to the Indenture Trustee) to the effect that
such recording is necessary either for the protection of the Noteholders or any
other Person secured hereunder or for the enforcement of any right or remedy
granted to the Indenture Trustee under this Indenture.

         Section 10.15 ISSUER OBLIGATION. No recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the Securities
Administrator, the Owner Trustee or the Indenture Trustee on the Notes or under
this Indenture or any certificate or other writing delivered in connection
herewith or therewith, against (i) the Indenture Trustee or the Owner Trustee in
its individual capacity, (ii) any owner of a beneficial interest in the Issuer
or (iii) any partner, owner, beneficiary, agent, officer, director, employee or
agent of the Indenture Trustee or the Owner Trustee in its individual capacity,
any holder of a beneficial interest in the Issuer, the Securities Administrator,
the Owner Trustee or the Indenture Trustee or of any successor or assign of the
Indenture Trustee or the Owner Trustee in its individual capacity, except as any
such Person may have expressly agreed (it being understood that the Indenture
Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity. For all purposes of this Indenture, in the performance of
any duties or obligations of the Issuer hereunder, the Owner Trustee shall be
subject to, and entitled to the benefits of, the terms and provisions of Article
VI, VII and VIII of the Trust Agreement.

         Section 10.16 NO PETITION. The Indenture Trustee and the Securities
Administrator, by entering into this Indenture, each Noteholder, by accepting a
Note, and each Certificateholder, by accepting a Certificate, hereby covenant
and agree that they will not at any time prior to one year from the date of
termination hereof, institute against the Depositor or the Issuer, or join in
any institution against the Depositor or the Issuer 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 Notes, this Indenture or any
of the Basic Documents; provided however, that nothing herein shall prohibit the
Indenture Trustee from filing proofs of claim in any proceeding.

         Section 10.17 INSPECTION. The Issuer agrees that, at its expense, on
reasonable prior notice, it shall permit any representative of the Indenture
Trustee or the Securities Administrator, during the Issuer's normal business
hours, to examine all the books of account, records, reports and other papers of
the Issuer, to make copies and extracts therefrom, to cause such books to be
audited by Independent certified public accountants, and to discuss the Issuer's
affairs, finances

<PAGE>


and accounts with the Issuer's officers, employees, and Independent certified
public accountants, all at such reasonable times and as often as may be

hold in confidence all such information except to the extent disclosure may be
required by law, regulation, judicial process or made to the Indenture Trustee's
auditors, regulators, attorneys or other governmental authorities and except to
the extent that the Indenture Trustee or the Securities Administrator may
reasonably determine that such disclosure is consistent with its obligations
hereunder.

         MortgageIT Trust 2005-1 (the "Issuer"), a Delaware statutory trust, for
value received, hereby promises to pay to Cede & Co. or registered assigns, the
principal sum of ($_________________) in monthly installments on the
twenty-fifth day of each month or, if such day is not a Business Day, the next
succeeding Business Day (each a "Payment Date"), commencing in February 2005 and
ending on or before the Payment Date occurring in February 2035 (the "Final
Scheduled Payment Date") and to pay interest on the Note Principal Balance of
this Note (this "Note") outstanding from time to time as provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2005-1 (the "Notes"), issued under an Indenture
dated as of January 19, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, National Association (the "Securities Administrator") and Deutsche Bank
National Trust Company, as indenture trustee (the "Indenture Trustee", which
term includes any successor Indenture Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights thereunder of the Issuer, the Indenture
Trustee, and the Holders of the Notes and the terms upon which the Notes are to
be authenticated and delivered. All terms used in this Note which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. The
"Note Principal Balance" of a Note as of any date of determination is equal to
the initial Note Principal Balance thereof, reduced by the aggregate of all
amounts previously paid with respect to such Note on account of principal and
the aggregate amount of cumulative Realized Losses allocated to such Note on all
prior Payment Dates.

         The principal of, and interest on, this Note are due and payable as
described in the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. All payments made by the Issuer with respect to this Note shall
be equal to this Note's pro rata share of the aggregate payments on all Class
[__]-A-[__] Notes as described above, and shall be applied as between interest
and principal as provided in the Indenture.


                                     A-1-2
<PAGE>


         All principal and interest accrued on the Notes, if not previously
paid, will become finally due and payable at the Final Scheduled Payment Date.

         The Notes are subject to redemption in whole, but not in part, by the
Majority Certificateholder 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.

         The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Notes. The assets included in the
Trust Estate will be the sole source of payments on the Class [__]-A-[__] Notes,
and each Holder hereof, by its acceptance of this Note, agrees that (i) such
Note will be limited in right of payment to amounts available from the Trust
Estate as provided in the Indenture and (ii) such Holder shall have no recourse
to the Issuer, the Securities Administrator, the Owner Trustee, the Indenture
Trustee, the Depositor, the Master Servicer, the Servicer or any of their
respective affiliates, or to the assets of any of the foregoing entities, except
the assets of the Issuer pledged to secure the Class [__]-A-[__] Notes pursuant
to the Indenture and the rights conveyed by the Issuer under the Indenture.

         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Note Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Note, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Note delivered to the Securities
Administrator at least five Business Days prior to the Record Date, any payment
of principal or interest, other than the final installment of principal or
interest, shall be made by wire transfer to an account in the United States
designated by such Holder. All scheduled reductions in the principal amount of a
Note (or one or more predecessor Notes) effected by payments of principal made
on any Payment Date shall be binding upon all Holders of this Note and of any
note issued upon the registration of transfer thereof or in exchange therefor or
in lieu thereof, whether or not such payment is noted on such Note. The final
payment of this Note shall be payable upon presentation and surrender thereof on
or after the Payment Date thereof at the office designated by the Securities
Administrator or the office or agency of the Issuer maintained by it for such
purpose pursuant to Section 3.02 of the Indenture.

         Subject to the foregoing provisions, each Note delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Note shall carry the right to unpaid principal and interest that were
carried by such other Note.

         If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Notes, the Notes may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs prior to the payment of the entire unpaid
Note Principal Balance of the Notes, the amount payable to the Holder of this
Note will be equal to the sum of the unpaid Note Principal Balance of the Notes,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture


                                     A-1-3
<PAGE>


provides that, notwithstanding the acceleration of the maturity of the Notes,
under certain circumstances specified therein, all amounts collected as proceeds
of the Trust Estate securing the Notes or otherwise shall continue to be applied
to payments of principal of and interest on the Notes as if they had not been
declared due and payable.

         The Holder of this Note or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Note with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Note will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and (B) the Notes are rated investment grade or better and such
person believes that the Notes are properly treated as indebtedness without
substantial equity features for purposes of the DOL Regulations, and agrees to
so treat the Notes. Alternatively, regardless of the rating of the Notes, such
person may provide the Securities Administrator and the Owner Trustee with an
Opinion of Counsel, which Opinion of Counsel will not be at the expense of the
Issuer, the Seller, any Underwriter, the Owner Trustee, the Indenture Trustee,
the Securities Administrator, the Master Servicer, the Servicer or any successor
servicer which opines that the acquisition, holding and transfer of such Note or
interest therein is permissible under applicable law, will not constitute or
result in a non-exempt prohibited transaction under ERISA or Section 4975 of the
Code and will not subject the Issuer, the Seller, the Depositor, any
Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer, the
Securities Administrator or the Servicer to any obligation in addition to those
undertaken in the Indenture.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note may be registered on the Note Register of
the Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Note at the office or agency designated
by the Issuer pursuant to the Indenture, accompanied by proper instruments of
assignment in form satisfactory to the Securities Administrator, one or more new
Notes of any authorized denominations and of a like aggregate initial Note
Principal Balance, will be issued to the designated transferee or transferees.

         Prior to the due presentment for registration of transfer of this Note,
the Issuer, the Indenture Trustee, the Securities Administrator and any agent of
the Issuer, the Securities Administrator or the Indenture Trustee may treat the
Person in whose name this Note is registered as the owner of such Note (i) on
the applicable Record Date for the purpose of making payments and interest of
such Note, and (ii) on any other date for all other purposes whatsoever, as the
owner hereof, whether or not this Note be overdue, and none of the Issuer, the
Securities Administrator, the Indenture Trustee or any such agent of the Issuer,
the Securities Administrator or the Indenture Trustee shall be affected by
notice to the contrary.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer and the Holders of a majority of all Notes at the time
outstanding. The Indenture also contains provisions permitting the Holders of
Notes representing specified percentages of the aggregate Note Principal Balance
of the Notes on behalf of the Holders of all the Notes, to waive any past
Default under the Indenture and its consequences. Any such waiver by the Holder,
at the time of the giving thereof, of this Note (or any one or more predecessor
Notes) shall bind the Holder of every Note issued upon the


                                     A-1-4
<PAGE>


registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not notation of such consent or waiver is made upon such Note. The Indenture
also permits the Issuer, the Indenture Trustee and the Securities Administrator
to amend or waive certain terms and conditions set forth in the Indenture
without the consent of the Holders of the Notes issued thereunder.

         Initially, the Notes will be registered in the name of Cede & Co. as
nominee of DTC, acting in its capacity as the Depository for the Notes. The
Notes will be delivered by the clearing agency in denominations as provided in
the Indenture and subject to certain limitations therein set forth. The Notes
are exchangeable for a like aggregate initial Note Principal Balance of Notes of
different authorized denominations, as requested by the Holder surrendering
same.

         Unless the Certificate of Authentication hereon has been executed by
the Securities Administrator by manual signature, this Note shall not be
entitled to any benefit under the Indenture, or be valid or obligatory for any
purpose.

         AS PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS
NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

and payable in the manner and with the effect provided in the Indenture. If any

Note will be equal to the sum of the unpaid Note Principal Balance of the Notes,
together with accrued and unpaid interest thereon as described in the Indenture.

amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer and the Holders of a majority of all Notes at the time
outstanding. The Indenture also contains provisions permitting the Holders of
Notes representing specified percentages of the aggregate Note Principal Balance
of the Notes on behalf of the Holders of all the Notes, to waive any past
Default under the Indenture and its consequences. Any such waiver by the Holder,
at the time of the giving thereof, of this Note (or any one or more predecessor
Notes) shall bind the Holder of every Note issued upon the registration of
transfer hereof or in exchange hereof or in lieu hereof, whether or not notation
of such consent or waiver is made upon such Note. The Indenture also permits the
Issuer, the Indenture Trustee and the Securities Administrator to amend or waive
certain terms and conditions set forth in the Indenture without the consent of
the Holders of the Notes issued thereunder.

         MortgageIT Trust 2005-1 (the "Issuer"), a Delaware statutory trust, for
value received, hereby promises to pay to Cede & Co. or registered assigns, the
principal sum of ______________________________ ($___________) in monthly
installments on the twenty-fifth day of each month or, if such day is not a
Business Day, the next succeeding Business Day (each a "Payment Date"),
commencing in February 2005 and ending on or before the Payment Date occurring
in February 2035 (the "Final Scheduled Payment Date") and to pay interest on the
Note Principal Balance of this Note (this "Note") outstanding from time to time
as provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2005-1 (the "Notes"), issued under an Indenture
dated as of January 19, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, National Association (the "Securities Administrator") and Deutsche Bank
National Trust Company, as indenture trustee (the "Indenture Trustee", which
term includes any successor Indenture Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights thereunder of the Issuer, the Indenture
Trustee, and the Holders of the Notes and the terms upon which the Notes are to
be authenticated and delivered. All terms used in this Note which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. The
"Note Principal Balance" of a Note as of any date of determination is equal to
the initial Note Principal Balance thereof, reduced by the aggregate of all
amounts previously paid with respect to such Note on account of principal and
the aggregate amount of cumulative Realized Losses allocated to such Note on all
prior Payment Dates.

         The principal of, and interest on, this Note are due and payable as
described in the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. All payments made by the Issuer with respect to this Note shall
be equal to this Note's pro rata share of the aggregate payments on all Class
[__]-B-[_] Notes as described above, and shall be applied as between interest
and principal as provided in the Indenture.

         All principal and interest accrued on the Notes, if not previously
paid, will become finally due and payable at the Final Scheduled Payment Date.


                                     A-3-2
<PAGE>


         The Notes are subject to redemption in whole, but not in part, by the
Majority Certificateholder on any Payment Date on or after the Payment Date on
which the aggregate Scheduled Principal Balance of the Mortgage Loans is less
than or equal to 20% of aggregate Scheduled Principal Balance of the Mortgage
Loans as of the Cut-off Date.

         The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Notes. The assets included in the
Trust Estate will be the sole source of payments on the Class [__]-B-[_] Notes,
and each Holder hereof, by its acceptance of this Note, agrees that (i) such
Note will be limited in right of payment to amounts available from the Trust
Estate as provided in the Indenture and (ii) such Holder shall have no recourse
to the Issuer, the Securities Administrator, the Owner Trustee, the Indenture
Trustee, the Depositor, the Master Servicer, the Servicer or any of their
respective affiliates, or to the assets of any of the foregoing entities, except
the assets of the Issuer pledged to secure the Class [__]-B-[_] Notes pursuant
to the Indenture and the rights conveyed by the Issuer under the Indenture.

         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Note Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Note, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Note delivered to the Securities
Administrator at least five Business Days prior to the Record Date, any payment
of principal or interest, other than the final installment of principal or
interest, shall be made by wire transfer to an account in the United States
designated by such Holder. All scheduled reductions in the principal amount of a
Note (or one or more predecessor Notes) effected by payments of principal made
on any Payment Date shall be binding upon all Holders of this Note and of any
note issued upon the registration of transfer thereof or in exchange therefor or
in lieu thereof, whether or not such payment is noted on such Note. The final
payment of this Note shall be payable upon presentation and surrender thereof on
or after the Payment Date thereof at the office designated by the Securities
Administrator or the office or agency of the Issuer maintained by it for such
purpose pursuant to Section 3.02 of the Indenture.

         Subject to the foregoing provisions, each Note delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Note shall carry the right to unpaid principal and interest that were
carried by such other Note.

         If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Notes, the Notes may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs prior to the payment of the entire unpaid
Note Principal Balance of the Notes, the amount payable to the Holder of this
Note will be equal to the sum of the unpaid Note Principal Balance of the Notes,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture provides that, notwithstanding the acceleration of the maturity of
the Notes, under certain circumstances specified therein, all amounts collected
as proceeds of the Trust Estate securing the Notes or otherwise shall continue
to be applied to payments of principal of and interest on the Notes as if they
had not been declared due and payable.
