          the following order with respect to each such Class: (a) the Accrued
          Note Interest thereon for such Payment Date (subject to Net Interest
          Shortfalls allocated to such Class) to the extent of any remaining
          Interest Funds; and (b) such Class's Allocable Share of the

     (b) If on any Payment Date on which the aggregate Note Principal Balance of
a Note Group would be greater than the aggregate Stated Principal Balance of the
Mortgage Loans in its related Mortgage Group and any Subordinated Notes are
still outstanding, in each case, after giving effect to distributions to be made
on such Payment Date, (i) 100% of amounts otherwise allocable to the
Subordinated Notes in respect of principal will be distributed to the Class 1-A,
Class 2-A, Class 3-A, Class 4-A or Class 5-A Notes, pro rata, as applicable, in
reduction of the Note Principal Balances thereof, until the Note Principal
Balance of the Class 1-A, Class 2-A, Class 3-A, Class 4-A or Class 5-A Notes, as

for such Payment Date prior to reduction for Net Interest Shortfalls and the
interest portion of Realized Losses, the shortfall will be allocated among the
holders of each Class of Senior Notes in such Note Group in proportion to the
respective amounts of Accrued Note Interest that would have been allocated
thereto in the absence of such Net Interest Shortfalls and/or Realized Losses
for such Payment Date. In addition, the amount of any interest shortfalls will
constitute unpaid Accrued Note Interest and will be distributable to holders of
the Notes of the related Classes entitled to such amounts on subsequent Payment
Dates, to the extent of the applicable Available Funds after current interest
distributions as required herein. Any such amounts so carried forward will bear
interest. Shortfalls in interest payments will not be offset by a reduction in
the servicing compensation of the Master Servicer or otherwise, except to the
extent of applicable Compensating Interest Payments.

     (e) Each distribution with respect to a Book-Entry Note shall be paid to
the Depository, as Holder thereof, and the Depository shall be responsible for

<PAGE>

of such distribution to the accounts of its Depository Participants in
accordance with its normal procedures. Each Depository Participant shall be
responsible for disbursing such distribution to the Note Owners that it
represents and to each indirect participating brokerage firm (a "brokerage firm"
or "indirect participating firm") for which it acts as agent. Each brokerage
firm shall be responsible for disbursing funds to the Note Owners that it
represents. None of the Securities Administrator, the Note Registrar, the Paying
Agent, the Depositor or the Master Servicer shall have any responsibility
therefor.

     (f) On each Payment Date, the Certificate Paying Agent shall deposit in the
Certificate Distribution Account all amounts it received pursuant to this
Section 3.03 for the purpose of distributing such funds to the
Certificateholders. The Certificate Paying Agent shall make distributions to the
Certificateholders under the Trust Agreement as directed by the Securities
Administrator hereunder.

     (g) Any installment of interest or principal, if any, payable on any Note
that is punctually paid or duly provided for by the Issuer on the applicable
Payment Date shall, if such Holder shall have so requested at least five
Business Days prior to the related Record Date, be paid to each Holder of record
on the preceding Record Date, by wire transfer to an account specified in
writing by such Holder as of the preceding Record Date or in all other cases or
if no such instructions have been delivered to the Securities Administrator, by
check to such Noteholder mailed to such Holder's address as it appears in the
Note Register in the amount required to be distributed to such Holder on such
Payment Date pursuant to such Holder's Notes; provided, however, that the
Securities Administrator shall not pay to such Holders any amount required to be
withheld from a payment to such Holder by the Code.

     (h) The Note Principal Balance of each Note shall be due and payable in
full on the Final Scheduled Payment Date for such Note as provided in the forms
of Note set forth in Exhibits A-1, A-2, A-3, and A-4 to this Indenture. All
principal payments on the Notes shall be made to the Noteholders entitled
thereto in accordance with the Percentage Interests represented by such Notes.
Upon notice to the Securities Administrator by the Issuer, the Securities
Administrator shall notify the Person in whose name a Note is registered at the
close of business on the Record Date preceding the Final Scheduled Payment Date
or other final Payment Date (including any final Payment Date resulting from any
redemption pursuant to Section 8.06 hereof). Such notice shall to the extent
practicable be mailed no later than five Business Days prior to such Final
Scheduled Payment Date or other final Payment Date and shall specify that
payment of the principal amount and any interest due with respect to such Note
at the Final Scheduled Payment Date or other final Payment Date will be payable
only upon presentation and surrender of such Note and shall specify the place
where such Note may be presented and surrendered for such final payment. No
interest shall accrue on the Notes on or after the Final Scheduled Payment Date
or any such other final Payment Date.

     Section 3.23 Certain Representations Regarding the Trust Estate.

     (a) With respect to that portion of the Collateral described in clauses (a)
through (c) of the definition of Trust Estate, the Issuer represents to the
Indenture Trustee that:

          (i) This Indenture creates a valid and continuing security interest
(as defined in the applicable UCC) in the Collateral in favor of the Indenture
Trustee, which security interest is prior to all other liens, and is enforceable
as such as against creditors of and purchasers from the Issuer.

          (ii) The Collateral constitutes "deposit accounts," "instruments" or
"certificated securities," as applicable within the meaning of the applicable
UCC.

          (iii) The Issuer owns and has good and marketable title to the
Collateral, free and clear of any lien, claim or encumbrance of any Person.

          (iv) The Issuer has caused or will have caused, within ten days of the
Closing Date, the filing of all appropriate financing statements in the proper
filing office in the

                                       14

<PAGE>

appropriate jurisdictions under applicable law in order to perfect the security
interest in the Collateral granted to the Indenture Trustee hereunder.

          (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. 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 the
Collateral other than any financing statement relating to the security interest
granted to the Indenture Trustee hereunder or that has been terminated.

          (vi) The Collateral is not in the name of any Person other than the
Issuer or the Indenture Trustee. The Issuer has in its possession all original
copies of the security certificates that constitute or evidence the Collateral.
The security certificates that constitute or evidence the Collateral do not have
any marks or notations indicating that they have been pledged, assigned or
otherwise conveyed to any Person other than 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.

     Section 3.24 Allocation of Realized Losses. (a) On or prior to each Payment
Date, the Master Servicer shall determine, based solely on information provided
to it by the Servicers the amount of any Realized Loss in respect of each
Mortgage Loan that occurred during the immediately preceding calendar month.

     (b) With respect to any Notes on any Payment Date, the principal portion of
each Realized Loss on a Mortgage Loan shall be allocated as follows:

     first, to the Class B-3 Notes until the Note Principal Balance thereof has
been reduced to zero;

     second, to the Class B-2 Notes until the Note Principal Balance thereof has
been reduced to zero;

     third, to the Class B-1 Notes until the Note Principal Balance thereof has
been reduced to zero;

     fourth, to the Class M-3 Notes until the Note Principal Balance thereof has
been reduced to zero;

     fifth, to the Class M-2 Notes until the Note Principal Balance thereof has
been reduced to zero;

     sixth, to the Class M-1 Notes until the Note Principal Balance thereof has
been reduced to zero;

     seventh, to the Class A Notes of the Note Group related to the Mortgage
Group in which such Realized Loss occurred as follows: (i) to the Class 1-A-2
Notes until the Note Principal Balance thereof has been reduced to zero and
thereafter to the Class 1-A-1 Notes, (ii) sequentially (a) to the Class 2-A-2
Notes and (b) pro rata (1) to the Class 2-A-1E Notes and (2) sequentially (A) to
the Class 2-A-1D Notes and (B) to the Class 2-A-1A, Class 2-A-1B and Class
2-A-1C Notes pro rata, until the Note Principal Balance of each such Class has
been reduced to

                                       15

<PAGE>

zero, (iii) to the Class 3-A-2 Notes until the Note Principal Balance thereof
has been reduced to zero and thereafter to the Class 3-A-1 Notes, (iv) to the
Class 4-A-2 Notes until the Note Principal Balance thereof has been reduced to
zero and thereafter to the Class 4-A-1 Notes and (v) to the Class 5-A-2 Notes
until the Note Principal Balance thereof has been reduced to zero and thereafter
to the Class 5-A-1 Notes;

     (c) Notwithstanding the foregoing clause (b), no such allocation of any
Realized Loss shall be made on a Payment Date to any Class or Classes of Notes
to the extent that such allocation would result in the reduction of the
aggregate Note Principal Balance of all of the Classes of Notes as of such
Payment Date, after giving effect to all distributions and prior allocations of
Realized Losses on such date, to an amount less than the aggregate Scheduled
Principal Balance of the Mortgage Loans as of the related Due Date (such
limitation, the "Loss Allocation Limitation").

     (d) The principal portion of any Realized Losses allocated to a Class of
Notes shall be allocated among the Notes of such Class in proportion to their
respective Note Principal Balances. Any allocation of Realized Losses shall be
accomplished by reducing the Note Principal Balance of the Notes on the related
Payment Date.

     (e) Realized Losses shall be allocated on the Payment Date in the month
following the month in which such loss was incurred and, in the case of the
principal portion thereof, after giving effect to distributions made on such
Payment Date.

     (f) [RESERVED].

     (g) The interest portion of any Realized Losses with respect to the
Mortgage Loans will be borne sequentially to the Class B-3, Class B-2, Class
B-1, Class M-3, Class M-2 and Class M-1 Notes, in that order. Once the aggregate
Note Principal Balance of the Subordinate Notes has been reduced to zero, the
interest portion of Realized Losses on the Mortgage Loans in a Mortgage Group
will be allocated to the Notes related to such Mortgage Group in the same order
and manner as set forth in subsection (b) of this Section 3.24.

     (h) In addition, in the event that the Securities Administrator receives
any Subsequent Recoveries from the Servicer or Master Servicer, the Securities
Administrator shall deposit such funds into the Payment Account pursuant to
Section 3.01 of this Indenture. 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 Notes with the highest payment priority to which Realized Losses have been
allocated, but not by more than the amount of Realized Losses previously
allocated to that Class or Classes of Notes pursuant to this Section 3.24. The
amount of any Subsequent Recoveries following the application set forth in the
immediately preceding sentence will be applied to sequentially increase the Note
Principal Balance of the Notes, beginning with the Class of Notes with the next
highest payment priority, up to the amount of such Realized Losses previously
allocated to such Class or Classes of Notes pursuant to this Section 3.24.
Holders of such Notes will not be entitled to any payments in respect of Accrued
Note Interest on the amount of such increases for any Interest Accrual Period
preceding the Payment Date on which such increase occurs. Any such increases
shall be applied to the Note Principal Balance of the Notes of such Class in
accordance with its respective Percentage Interest.

withdrawal pursuant to the Sale and Servicing Agreement or as the Securities
Administrator has instructed hereunder for the following purposes (limited in

or the related Servicer from Liquidation Proceeds from a particular Mortgage
Loan for Liquidation Expenses incurred with respect to such Mortgage Loan;
provided that the Master Servicer shall not be entitled to reimbursement for
Liquidation Expenses with respect to a Mortgage Loan to the extent that (i) any
amounts with respect to such Mortgage Loan were paid as Excess Liquidation
Proceeds pursuant to clause (viii) of this Subsection 3.25 (a) to the Master
Servicer; and (ii) such Liquidation Expenses were not included in the
computation of such Excess Liquidation Proceeds;

          (iv) to reimburse the Master Servicer or the related Servicer for
advances of funds (other than Monthly Advances) made with respect to the

          (vii) to reimburse the Master Servicer for expenses, costs and
liabilities incurred by and reimbursable to it pursuant to Sections 3.02,
5.04(c) and (d) of the Sale and Servicing Agreement, to the extent that the
Master Servicer has not already reimbursed itself for such amounts from the
Master Servicer Collection Account;

          (viii) to pay to the Master Servicer, as additional servicing
compensation, any Excess Liquidation Proceeds to the extent not retained by the
related Servicer;

          (ix) to reimburse or pay the related Servicer any such amounts as are
due thereto under the related Servicing Agreements and have not been retained by
or paid to the related Servicer, to the extent provided in the related Servicing
Agreement;

          (x) to reimburse or pay the Indenture Trustee, the Owner Trustee, the

                                   ARTICLE IV

               THE NOTES; SATISFACTION AND DISCHARGE OF INDENTURE

     Section 4.01 The Notes. Each Class of the Class 1-A-1, Class 2-A-1A, Class
2-A-1B, Class 2-A-1C, Class 2-A-1D, Class 2-A-1E, Class 2-A-2, Class 3-A-1,
Class 4-A-1 and Class 5-A-1 Notes shall be registered in the name of a nominee
designated by the Depository. Beneficial Owners will hold interests in the Class
1-A-1, Class 2-A-1A, Class 2-A-1B, Class 2-A-1C, Class 2-A-1D, Class 2-A-1E,
Class 3-A-1, Class 4-A-1 and Class 5-A-1 Notes through the book-entry facilities
of the Depository in minimum initial Note Principal Balances of $25,000 and
integral multiples of $1 in excess thereof. Initially, Registered Holders will
hold interests in the Class 1-A-2, Class 3-A-2, Class 5-A-2 Notes in physical
form in minimum initial Note Principal Balances of $100,000 and integral
multiples of $1 in excess thereof; provided, however, such notes may later be
designated Book-Entry Notes and be registered in the name of a nominee
designated by the Depository. Registered Holders will hold interests in the
Class 4-A-2, Class M-1, Class M-2, Class M-3, Class B-1, Class B-2 and Class B-3
Notes in physical form in minimum initial Note Principal Balances of $100,000
and integral multiples of $1 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 Securities Administrator, not in its individual capacity but solely as
Securities Administrator, authenticated by the Securities Administrator and
delivered by the Securities Administrator on behalf of the Owner Trustee 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 Corporate Trust Office of the Securities Administrator a
Note Register in which, subject to such

                                       19

<PAGE>

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 of transfer of any Note at the Corporate Trust Office of the
Securities Administrator, 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.

     No transfer, sale, pledge or other disposition of any Privately Offered
Note or interest therein shall be made unless that transfer, sale, pledge or
other disposition is exempt from the registration and/or qualification
requirements of the Securities Act and any applicable state securities laws, or
is otherwise made in accordance with the Securities Act and such state
securities laws. If a transfer of any Privately Offered Note is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or a transfer thereof to the Depositor or one of its
Affiliates), then the Note Registrar shall refuse to register such transfer
unless (i) it receives (and upon receipt, may conclusively rely upon) a
certificate substantially in the form attached as Exhibit C hereto (provided,
however, that in the case of the Book-Entry Notes, the Noteholder and the
Noteholder's prospective transferee will be deemed to have made the
representations set forth in such certification) or (ii) (a) it receives a
written Opinion of Counsel acceptable to and in form and substance satisfactory
to the Note Registrar, the Securities Administrator and the Indenture Trustee
that such transfer may be made pursuant to an exemption, describing the
applicable exemption and the basis therefor, from the Securities Act and any
applicable state securities laws or is being made pursuant to the Securities Act
and any applicable state securities laws, which Opinion of Counsel shall not be
an expense of the Issuer, the Seller, the Owner Trustee, the Indenture Trustee,
the Securities Administrator, the Master Servicer or any Servicer and (b) the
transferee executes a representation letter, substantially in the form of
Exhibit D attached hereto, and transferor executes a representation letter,
substantially in the form of Exhibit E hereto, each acceptable to and in form
and substance satisfactory to the Note Registrar, the Securities Administrator
and the Indenture Trustee certifying the facts surrounding such transfer, which
representation letters shall not be an expense of the Issuer, the Seller, the
Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master
Servicer or any Servicer. None of the Issuer, the Depositor, the Indenture
Trustee, the Securities Administrator or the Note Registrar is obligated to
register or qualify any Notes under the Securities Act or any other securities
law or to take any action not otherwise required under this Indenture to permit
the transfer of any Note or interest therein without registration or
qualification. Any Noteholder desiring to effect a transfer of Notes or
interests therein shall, and does hereby agree to, indemnify the Issuer, the
Depositor, the Owner Trustee, the Indenture Trustee, the Securities
Administrator and the Note Registrar against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws or in accordance with any restrictions on transfer set forth in this
Indenture. Notwithstanding the foregoing, the provisions of this paragraph shall
not apply to the initial transfer of the Notes to the Depositor or any Affiliate
thereof.

     No transfer, sale, pledge or other disposition of any Senior Note or
Privately Offered Notes (other than (A) (i) an Initial Transfer of a Senior Note
with respect to which (x) a certificate substantially in the form of Exhibit I
hereto (a "Tax Transfer Certificate") has been furnished to the Securities
Administrator or (y) a "will be debt" opinion has been rendered by

                                       20

<PAGE>

nationally recognized tax counsel and furnished to the Securities Administrator,
or (ii) an Initial Transfer of a Privately Offered Note with respect to which a
"will be debt" opinion has been rendered by nationally recognized tax counsel
and furnished to the Securities Administrator or (B) a Subsequent Transfer of a
Senior Note or Privately Offered Note) or interest therein shall be made, and
the Note Registrar shall refuse to register any such transfer, sale, pledge or
other disposition, unless the transferee shall have delivered to the Owner
Trustee, the Note Registrar, the Securities Administrator and the Indenture
Trustee a certificate substantially in the form of Exhibit F hereto certifying
that (i) it is a real estate investment trust ("REIT") within the meaning of
Section 856(a), or a qualified REIT subsidiary ("QRS") within the meaning of
Section 856(i) of the Code, or an entity disregarded as an entity separate from
a REIT or a QRS and (ii) following the transfer, 100% of the Class 4-A-2 Notes,
Subordinate Notes and Certificates (other than Class 4-A-2 Notes or Subordinate
Notes, with respect to which a "will be debt" opinion has been rendered by
nationally recognized tax counsel and furnished to the Securities Administrator)
will be owned by a single REIT, directly or indirectly through one or more QRSs
of such REIT or one or more entities disregarded as entities separate from such
REIT or such QRSs; provided that, notwithstanding the foregoing, (x) any Senior
Notes or Privately Offered Notes may be pledged to secure indebtedness and may
be the subject of repurchase agreements treated by the Issuer as secured
indebtedness for federal income tax purposes, and (y) any Senior Notes or
Privately Offered Notes may be transferred by the related lender under any such
related loan agreement or repurchase agreement upon a default under any such
indebtedness, in which case the transferor shall deliver to the Note Registrar
and the Securities Administrator a certificate substantially in the form
attached hereto as Exhibit G certifying to such effect.

     Subject to the foregoing, and Section 4.08, 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 Corporate Trust Office of the Note Registrar.
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 its Corporate Trust Office a Certificate Register pursuant
to Section 3.08 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 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 Securities Administrator shall execute, and upon
the written request of the Issuer 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.

     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 or
the Paying Agent 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 Securities Administrator, the Indenture
Trustee or the Paying Agent 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 Form of Notes. The Class 1-A-1, Class 2-A-1A, Class 2-A-1B,
Class 2-A-1C, Class 2-A-1D, Class 2-A-1E, Class 2-A-2, Class 3-A-1, Class 4-A-1
and Class 5-A-1 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. These 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:

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

          (ii) the Note Registrar, the Paying Agent, the Indenture Trustee 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.

                                       23

<PAGE>

     None of the Depositor, the Issuer, the Master Servicer, the Seller, the
Securities Administrator, the Indenture Trustee, the Note Registrar and the
Owner Trustee shall have any liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Book-Entry
Notes or for maintaining, supervising or reviewing any records relating to
beneficial ownership interests or transfers thereof.

     The Class 1-A-2, Class 3-A-2, Class 4-A-2, Class 5-A-2, Class M-1, Class
M-2, Class M-3, Class B-1, Class B-2 and Class B-3 Notes will be registered in
full definitive form.

     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 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
Issuer shall execute and the Securities Administrator shall authenticate a new

                                       24

<PAGE>

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 Class 1-A, Class 2-A, Class 3-A, Class 4-A-1 and Class 5-A Notes will be
issued with the intention that, for federal, state and local income, single
business and franchise tax purposes, such Classes of Notes will qualify as
indebtedness at any time at which such Notes are treated as issued and
outstanding for federal income tax purposes. The Issuer and the Securities
Administrator (in accordance with Section 6.07 hereof), by entering into this
Indenture, and each Class 1-A, Class 2-A, Class 3-A, Class 4-A-1 and Class 5-A
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
such Classes of Notes for federal, state and local income, single business and
franchise tax purposes as indebtedness at any time at which such Notes are
treated as issued and outstanding for federal income tax purposes.

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 and immunities of the Indenture
Trustee and Securities Administrator hereunder (including the rights of the
Securities Administrator under Section 6.08 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
Securities Administrator 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

          (A) either

          (1) all Notes theretofore authenticated and delivered (other than (i)
     Notes that have been destroyed, lost or stolen and that 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,

and the Issuer, in the case of a. or 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 c. above, the Issuer shall have
complied with all requirements of Section 8.06 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
and applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent or the
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 3.03 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.

                                       26

<PAGE>

     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

     Section 4.15 Representation Regarding ERISA.

     Each investor in a Class A Note (other than a Class 1-A-2 Note, a Class
3-A-2 Note, a Class 4-A-2 Note, or a Class 5-A-2 Note) or any interest therein
will be deemed to have represented and agreed either (I) that it is not a Plan,
or a plan subject to any provisions under any federal, state, local, non-U.S. or
other laws or regulations that are substantively similar to Title I of ERISA or
Section 4975 of the Code ("Similar Law"), and it is not directly or indirectly
acquiring such Note for, on behalf of or with any assets of any such Plan or
plan subject to Similar Law or (II) that it is a Person described in clause (I)
and its acquisition and holding of this Note, or any interest herein, will not
constitute or result in a non-exempt prohibited transaction under ERISA or the
Code, or a violation of Similar Law, and will not subject the Issuer, the
Seller, the Depositor, the Owner Trustee, the Indenture Trustee, the Securities
Administrator, the Note Registrar, the Master Servicer or any Servicer to any
obligation in addition to those undertaken by the Issuer, the Indenture Trustee
or the Owner Trustee in the Indenture.

     Each investor in a Class B Note or any interest therein will be deemed to
have represented and agreed either that it (A) is not a Plan, and it is not
directly or indirectly acquiring the Class B Note for, on behalf of or with any
assets of any such Plan, or (B) is a plan subject to Similar Law, and the
acquisition and holding of the Class B Note by such plan subject to Similar Law
will not constitute or result in a violation of Similar Law, or subject the
Issuer, the Seller, the Depositor, the Owner Trustee, the Indenture Trustee, the
Securities Administrator, the Note Registrar, the Master Servicer, or any
Servicer to any obligation in addition to those undertaken by the Issuer, the
Seller, the Depositor, the Indenture Trustee, the Owner Trustee, the Securities
Administrator, the Note Registrar, the Master Servicer, or any Servicer in the
Indenture.

     Except in the case of a Definitive Note, the representations set forth in
the immediately preceding two paragraphs shall be deemed to have been made to
the Securities Administrator by the transferee's acceptance of a Class A Note
(other than a Class 1-A-2 Note, a Class 3-A-2 Note, a Class 4-A-2 Note, or a
Class 5-A-2 Note) or a Class B Note (or the acceptance by a Note Owner of the
beneficial interest in any such Notes).

     Notwithstanding any other provision herein to the contrary, any purported
transfer of a Class A Note (other than a Class 1-A-2 Note, a Class 3-A-2 Note, a
Class 4-A-2 Note, or a Class 5-A-2 Note) or a Class B Note to or on behalf of a
Plan or a plan subject to Similar Law without the delivery to the Securities
Administrator of a representation or an Opinion of Counsel satisfactory to the
Securities Administrator as described above shall be void and of no effect. The
Securities Administrator shall not be under any liability to any Person for any
registration or transfer of any such Notes that is in fact not permitted by this
Section 4.15, nor shall the

                                       27

<PAGE>

Indenture Trustee or the Securities Administrator be under any liability for
making any payments due on such Note to the Holder thereof or taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the transfer was registered by the Securities Administrator in
accordance with the foregoing requirements. The Trustee or the Securities
Administrator shall be entitled, but not obligated, to recover from any Holder
of any Class A Note (other than a Class 1-A-2 Note, a Class 3-A-2 Note, a Class
4-A-2 Note, or a Class 5-A-2 Note) or Class B Note that was in fact a Plan or
plan subject to Similar Law and that held such Note in violation of this Section
4.15 all payments made on such Notes at and after the time it commenced such
holding. Any such payments so recovered shall be paid and delivered to the last
preceding Holder of such Note that is not a Plan or plan subject to Similar Law.

                              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 a 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 (ii), (iii) or (iv) 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 Default or
Event of Default unless a Responsible Officer has actual knowledge thereof or
unless written notice of such Default or 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 Senior Notes
representing not less than a majority of the aggregate Note Principal Balance of
the Notes may declare such 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 such 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 Senior Notes representing not less than
a majority of the aggregate Note Principal Balance of each Class of 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 Senior Notes
     and all other amounts that would then be due hereunder or under the Senior
     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

          (ii) all Events of Default, other than the nonpayment of the principal
of the Senior 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 Senior 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 Senior
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 Balance of the Senior Notes, pay to the Securities
Administrator, for the benefit of the Holders of such Notes, the whole amount
then due and payable on such Notes for principal and interest, with interest at
the applicable Note 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 10.15 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 upon 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 10.15 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 Balance of each Class of Senior 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 Balance of each Class of 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:

          (i) to file and prove a claim or claims for the whole amount of
principal and interest owing and unpaid in respect of the Senior 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

                                       30

<PAGE>

(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, willful misconduct 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.

     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 10.15 hereof, may, and shall, at the written direction of
the Holders of a majority of the aggregate Note Principal Balance of the Senior
Notes, 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 Senior 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 Senior Notes then outstanding, (B) the proceeds of
such sale or liquidation distributable to the Holders of the Senior Notes are
sufficient to discharge in full all amounts then due and unpaid upon such Senior
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 Senior Notes as they would have become due
if the Senior Notes had not been declared due and payable, and the Indenture
Trustee obtains the consent of the Holders of 66 2/3% of the aggregate Note
Principal Balance of each Class of Senior Notes then outstanding, voting
separately. 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, any Sale of the Trust
Estate shall be made subject to the continued servicing of the Mortgage Loans by
the Servicer (other than any Servicer as to which an Event of Servicer
Termination has occurred and is continuing) as provided in the Sale and
Servicing Agreement.

     (b) If the Indenture Trustee or the Securities Administrator collects any
money or property pursuant to this Article V, the Securities Administrator shall
pay out the money or property in the following order:

          FIRST: to the Indenture Trustee, the Securities Administrator, Master
     Servicer, the Owner Trustee, the Custodian and the Servicers for amounts
     due and not previously paid pursuant to the Indenture and the other Basic
     Documents;

                                       32

<PAGE>

          SECOND: to the Class 1-A, Class 2-A, Class 3-A, Class 4-A and Class
     5-A Noteholders, pro rata, for amounts due and unpaid on such Notes with
     respect to interest, according to the amounts due and payable on each such
     Notes for interest;

          THIRD: to the Class 1-A, Class 2-A, Class 3-A, Class 4-A and Class 5-A
     Noteholders, pro rata, for amounts due and unpaid on such Notes with
     respect to principal, and to each such Noteholder ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on such Notes for principal, until the Note Principal Balance of
     each such Class is reduced to zero;

          FOURTH: first, to the Class M-1 Noteholders, second, to the Class M-2
     Noteholders, third, to the Class M-3 Noteholders, fourth, to the Class B-1
     Noteholders, fifth, to the Class B-2 Notes and sixth, to the Class B-3
     Notes, according to the amounts due and payable on such Classes of Notes
     for interest and principal; and

          FIFTH: to the holders of the Trust Certificates on behalf of the
     Issuer.

     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 foregoing and the provisions of
Section 10.15 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
Balance of the Senior 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
reasonable indemnity against the costs, expenses and liabilities to be incurred
in complying with such request;

                                       33

<PAGE>

          (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 Senior 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 aggregate Note Principal Balance of the Senior Notes, the
Indenture Trustee shall take such action as requested by the Holders
representing the highest amount (in the aggregate) of the 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 Senior Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest, if any, on 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

                                       34

<PAGE>

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 Balance of Senior 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; provided that:

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

          (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
aggregate Note Principal Balance of the Senior Notes or the Holders of 66 2/3%
of the aggregate Note Principal Balance of each Class of Senior Notes then
outstanding, voting separately as set forth in Section 5.04(a) hereof; 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 the Senior Notes representing a majority of the aggregate Note
Principal Balance of the Senior Notes.

     Notwithstanding the rights of Noteholders set forth in this Section 5.11
the Indenture Trustee need not take any action that it determines might involve
it in 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 each Class of Senior 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 Senior 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 Senior 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

                                       35

<PAGE>

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 Senior 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 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 Sections 5.05 and
5.11(ii) 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 Senior 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 Senior 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, 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 100% of the Note Principal Balances of the Senior 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) Subject to this Section 5.15, unless the Holders representing at least
100% of the aggregate Note Principal Balance of the Senior Notes or the Holders
of 66 2/3% of the aggregate Note Principal Balance of each Class of Senior Notes
then outstanding, voting separately as set forth in Section 5.04(a) hereof, have
otherwise consented or directed the

                                       36

<PAGE>

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, as trustee for the benefit of the Holders of the
Notes, 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.

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

          (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 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

                                       37

<PAGE>

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 in accordance with Section
5.04(b) hereof.

     Section 6.01 Duties of Indenture Trustee and Securities Administrator. (a)
If an Event of Default 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 their 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 undertakes
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 conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon
certificates, reports, documents, Issuer Requests or other instruments or
opinions furnished to each of the Indenture Trustee and the Securities
Administrator and conforming to the requirements of this Indenture or the other
Basic Documents; however, the Indenture Trustee and the Securities Administrator
shall examine the certificates, reports, documents, Issuer Requests or other
instruments 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 not 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, the
Certificateholders 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 set forth in the Basic Documents and as the Indenture
Trustee may agree in writing with the Issuer.

                                       39

<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 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.

     (h) The Indenture Trustee shall not be deemed to have notice or knowledge
of any Default or Event of Default unless a Responsible Officer of the Indenture
Trustee has actual knowledge thereof or unless written notice of any such event
that is in fact an Event of Default or Default is received by the Indenture
Trustee at its Corporate Trust Office and such notice references the Notes or
Certificates generally, the Issuer, the Trust Estate or this Indenture.

     Section 6.02 Rights of Indenture Trustee and Securities Administrator. (a)

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 and
in accordance with 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.

     (d) The Indenture Trustee or the Securities Administrator may consult with
counsel, and the written 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, the other Basic Documents 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 written 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 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 Securities Administrator or its Affiliates are permitted to receive
additional compensation that could be deemed to be in the Securities
Administrator'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 Securities Administrator (i) as
part of the compensation 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 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
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 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
offered to the Indenture Trustee or the Securities Administrator, as applicable,
reasonable security or indemnity 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.

                                       41

     (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 by the security afforded to it by the terms of this Indenture. The
Indenture Trustee or the Securities Administrator may require reasonable
indemnity 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 Default or 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.

     Section 6.03 Individual Rights of Indenture Trustee. The Indenture Trustee
in its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Issuer or its Affiliates with the same 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 must comply with
Section 6.12 hereof.

     Section 6.04 [Reserved].

     Section 6.05 Indenture Trustee's and Securities Administrator's Disclaimer.
Neither the Indenture Trustee nor the Securities Administrator shall be
responsible for and makes no

                                       42

<PAGE>

representation as to the validity or adequacy of this Indenture, the Notes or
any other Basic Document, it shall not be accountable for the Issuer's use of
the proceeds from the Notes, and it shall not be responsible for any statement
of the Issuer in the Indenture or in any document issued in connection with the
sale of the Notes or in the Notes other than the Securities Administrator's
certificate of authentication.

     Section 6.06 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 it is known to a Responsible Officer of the Indenture Trustee,
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 best interests of Noteholders.

     Section 6.07 Reports to Holders and Tax Administration.

     The Seller shall provide to the Securities Administrator, and the
Securities Administrator shall then deliver to each Noteholder, such information
as may be required and such other customary information as the Seller may
determine and/or be required by the Internal Revenue Service or by a federal or
state law or rules or regulations to enable a Noteholder to prepare its federal
and state income tax returns.

     The Seller 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 Form 1099. All tax
returns and information reports shall be signed by the Owner Trustee or to the
extent permitted by law, the Securities Administrator as provided in Section
5.03 of the Trust Agreement.

     To the extent that a Responsible Officer of the Securities Administrator
becomes aware that the Seller no longer qualifies as a REIT within the meaning
of Section 856(a) of the Code, or that the Issuer no longer qualifies as a QRS
within the meaning of Section 856(i) of the Code, or an entity disregarded as an
entity separate from a REIT or a QRS, the Securities Administrator shall provide
notice of such fact to each Noteholder.

     Section 6.08 Compensation. An annual fee shall be paid to the Indenture
Trustee by the Master Servicer pursuant to a separate agreement between the
Indenture Trustee and the Master Servicer. In addition, the Indenture Trustee
and the Securities Administrator will each be entitled to recover from the
Payment Account pursuant to Section 3.25 of this Indenture all reasonable
out-of-pocket expenses, disbursements and advances and the expenses of the
Indenture Trustee and the Securities Administrator, respectively, in connection
with any breach of this Indenture 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

                                       43

<PAGE>

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 Indenture (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.

     The Issuer's payment obligations to the Indenture Trustee and Securities
Administrator pursuant to this Section 6.08 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 6.09 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
a successor Securities Administrator shall become effective until the acceptance
of appointment by the successor Indenture Trustee pursuant to this Section 6.09.
The Indenture Trustee or the Securities Administrator may resign at any time by
so notifying the Issuer. In the event that the Indenture Trustee determines that
a conflict of interest exists between the Holders of the Class A Notes and the
Holders of any Class of Subordinate Notes, then the Indenture Trustee shall be
entitled to resign as the indenture trustee for all Classes of Notes other than
the Class A Notes. In such event the Holders of a majority of Note Principal
Balances of all of the Subordinate Notes shall designate a separate indenture
trustee to represent their interests hereunder. Holders of a majority of Note
Principal Balances of each Class of Notes may remove the Indenture Trustee by so
notifying the Indenture Trustee and may appoint a successor Indenture Trustee.
The Issuer shall remove the Indenture Trustee or the Securities Administrator,
as applicable, if:

          (i) the Indenture Trustee or the Securities Administrator fails to
comply with or qualify pursuant to the provisions of Section 6.12 hereof;

          (ii) the Indenture Trustee or the Securities Administrator is adjudged
a bankrupt or insolvent;

          (iii) a receiver or other public officer takes charge of the Indenture
Trustee or the Securities Administrator or its property;

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

          (v) the Master Servicer is terminated pursuant to Section 5.01 of the
Servicing Agreement.

     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

                                       44

<PAGE>

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. The successor Indenture
Trustee or successor Securities Administrator shall each 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 6.10 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 under Section 6.12 hereof.
The Indenture Trustee and the Securities Administrator shall provide the Rating
Agencies and the Issuer with prior written notice, and the Noteholders with
prompt written notice, of any such transaction.

     If at the time such successor or successors by merger, conversion or
consolidation to the Indenture Trustee shall succeed to the trusts created by
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 is in the Notes or in this Indenture provided
that the certificate of the Indenture Trustee shall have.

     Section 6.11 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

                                       45

<PAGE>

any legal requirement of any jurisdiction in which any part of the Trust Estate
may at the time be located, the Indenture 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 6.12 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 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 separately, as may be provided therein, subject to all the
provisions of this 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 Trustee.

     (d) Any separate trustee or co-trustee may at any time constitute 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.

herein, the Securities Administrator may demand payment or delivery of, and
shall receive and collect, directly and without intervention or assistance of
any fiscal agent or other intermediary, all money and other property payable to
or receivable by the Securities Administrator pursuant to this Indenture. The
Securities Administrator shall apply all such money received by it as provided
in this Indenture. Except as otherwise expressly provided in this Indenture, if
any default occurs in the making of any payment or performance under any
agreement or instrument that is part of the Trust Estate, the Indenture Trustee
may take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate
Proceedings. Any such action shall be without prejudice to any right to claim a
Default or Event of Default under this Indenture and any right to proceed
thereafter as provided in Article V.

     Section 8.02 Officer's Certificate. The Indenture Trustee shall receive at
least seven Business Days' notice when requested by the Issuer to take any
action pursuant to Section 8.06(a) hereof, accompanied by copies of any
instruments to be executed, and the Indenture Trustee shall also require, as a
condition to such action, an Officer's Certificate, in form and substance
satisfactory to the Indenture Trustee, stating the legal effect of any such
action, outlining the steps required to complete the same, and concluding that
all conditions precedent to the taking of such action have been complied with.

     Section 8.03 Termination Upon Distribution to Noteholders. This Indenture
and the respective obligations and responsibilities of the Issuer, the
Securities Administrator and the Indenture Trustee created hereby shall
terminate upon the distribution to Noteholders, the Certificate Paying Agent on
behalf of the Certificateholders, the Securities Administrator and the Indenture
Trustee of all amounts required to be distributed pursuant to Article III;
provided, however, that in no event shall the trust created hereby continue
beyond the expiration of 21 years from the death of the survivor of the
descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof.

     Section 8.04 Release of Trust Estate. (a) Subject to the payment of its
fees and expenses, the Indenture Trustee may, and when required by the
provisions of this Indenture shall, execute instruments 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 that are not inconsistent with the
provisions of this Indenture, including for the purposes of any purchase of a
Mortgage Loan by the Majority Certificateholder pursuant to Section 8.06 of this
Indenture. No party relying upon an instrument executed by the Indenture Trustee
as provided in 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

then due and unpaid 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.

                                       51

<PAGE>

     (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.

     Section 8.05 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 8.06 Optional Redemption of the Mortgage Loans. (a) The Majority
Certificateholder shall have the option to purchase the assets of the Trust and
thereby cause the redemption of the Notes, in whole, but not in part, 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 10% or less of Cut-off
Date Scheduled Principal Balance of the Mortgage as of the Closing Date. The
aggregate redemption price (the "Redemption Price") for the Notes will be equal
to 100% of the aggregate outstanding 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 Rate through such Payment Date (including any related Net
Interest Shortfall and Basis Risk Shortfall Carryover Amount), 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 in writing upon request of the Issuer, the Indenture
Trustee, the Master Servicer and the Securities Administrator, as applicable).

     (b) In order to exercise the foregoing option, the Majority
Certificateholder shall provide written notice of its exercise of such option to
the Securities Administrator, the Issuer, the Owner Trustee and the Master
Servicer at least 15 days prior to its exercise. Following receipt of the
notice, the Securities Administrator shall provide written 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 Redemption
Price specified in (a) above with the Securities Administrator, who shall
deposit the 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 3.03 hereof and
payment to the Securities Administrator and the Master Servicer as set forth in
(a) above, 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 such redemption or such redemption
cannot be completed for any reason, (a) 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 and (b) the Note
Principal Balance of the Notes shall continue to bear interest at the related
Note Rate.

to time, may enter into one or more indentures supplemental hereto, 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

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

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; provided further, that such supplemental indenture will be
deemed to not materially and adversely affect the interests of the Holders of
the Notes if a Rating Confirmation is received with respect to such supplemental

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

provided, however, that no such indenture supplements shall be entered into
unless the Indenture Trustee and the Securities Administrator 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 and to the effect that (i) such indenture supplement is permitted
hereunder and will not materially and adversely affect the Holders of the Notes,
(ii) entering into such indenture supplement will not result in a "substantial
modification" of the Notes under Treasury Regulation Section 1.1001-3 or

                                       53

<PAGE>

of Notes with respect to which a "will be debt" opinion has been rendered by
nationally recognized tax counsel and furnished to the Securities Administrator
and (iii) such indenture supplement does not materially and adversely affect the
transfer restrictions with respect to the Senior Notes set forth in Section

     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 may, also without the consent of any of
the Holders of the Notes 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 permitted by this Indenture, (ii) shall not
adversely affect in any material respect the interests of any Noteholder, (iii)
if 100% of the Certificates and Privately Offered Notes (other than any
Privately Offered Notes with respect to which a "will be debt" opinion has been
rendered by nationally recognized tax counsel and furnished to the Securities
Administrator) are not owned by the Holder of the Trust Certificates, shall
not cause the Issuer to be subject to an entity level tax for federal income
tax purpose and (iv) such action does not materially and adversely affect
the transfer restrictions with respect to the Senior Notes set forth in
Section 4.02.

     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 Agencies and, with
the consent 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
and 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;

          (ii) reduce the percentage of the Note Principal Balances of the
Notes, or any Class of 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

                                       54

<PAGE>

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, or any Class of 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 (i) such action shall not, as evidenced by an
Opinion of Counsel, cause the Issuer, if 100% of the Senior Notes, Privately
Offered Notes and Certificates (other than any Senior Notes or Privately Offered
Notes with respect to which a "will be debt" opinion has been rendered by
nationally recognized tax counsel and furnished to the Securities Administrator)
are not owned by the Investor, to be subject to an entity level tax for federal
income tax purposes and (ii) such action does not materially and adversely
affect the transfer restrictions with respect to the Senior Notes set forth in
Section 4.02.

     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 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.

     Section 9.03 Execution of Supplemental Indentures. In executing, or
permitting the additional trusts created by, any supplemental indenture
permitted by this Article IX or the modification thereby of the trusts created
by this Indenture, the Indenture Trustee and the Securities Administrator shall
be entitled to receive, and subject to Sections 6.01 and 6.02 hereof, shall be
fully protected in relying upon, an Opinion of Counsel not at the expense of the
Indenture Trustee or the Securities Administrator stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Indenture Trustee and the Securities Administrator each may, but shall not be
obligated to, enter into any such supplemental indenture that affects the
Indenture Trustee's or the Securities Administrator's own rights, duties,
liabilities or immunities under this Indenture or otherwise.

     Section 9.04 Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and shall be deemed to be modified and amended in accordance therewith with
respect to the Notes affected thereby, and the respective rights, 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

so long as this Indenture shall then be qualified under the Trust Indenture Act.

     Section 9.06 Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Securities Administrator
shall, bear a notation in form approved by the Securities Administrator as to
any matter provided for in such supplemental indenture. If the Issuer or the
Securities Administrator shall so determine, new Notes so modified as to
conform, in the opinion of the Securities Administrator and the Issuer, to any
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 to take any action
under any provision of this Indenture, the Issuer shall furnish to the Indenture
Trustee (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.

     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".

     (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.

          (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 (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

                                       57

<PAGE>

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 then outstanding 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 outstanding 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 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 Issuer, Securities
Administrator 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:

          (i) the Indenture Trustee by any Noteholder or by the Issuer shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Indenture Trustee at the Corporate Trust Office. The
Indenture Trustee shall promptly transmit any notice received by it from the
Noteholders to the Issuer;

          (ii) the Securities Administrator by any Noteholder or by the Issuer
shall be sufficient for every purpose hereunder if made, given, furnished or
filed in writing to or with the Securities Administrator at Wells Fargo Bank,

Attn: Merrill Lynch Mortgage Investors Trust, Series 2005-A9, 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; or

          (iii) the Issuer by the Indenture Trustee or by any Noteholder shall
be sufficient for every purpose hereunder if made, given, furnished or filed in
writing and mailed first-class, postage prepaid to the Issuer addressed to:
Merrill Lynch Mortgage Investors Trust, Series 2005-A9, in care of Wilmington
Trust Company, Rodney Square North, 1100 North Market Street, Wilmington,
Delaware 19890-0001, 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.

     Notices required to be given to the Rating Agencies by the Issuer, the
Indenture Trustee, the Securities Administrator or the Owner Trustee shall be in
writing, mailed first-class postage pre-paid: in the case of Fitch, to Fitch,
Inc., One State Street Plaza, New York, New York 10004; and in the case of S&P,
Standard & Poor's, a division of The McGraw-Hill Companies, Inc., 55 Water
Street, New York, New York 10041; or as to each of the foregoing, 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 made, given, furnished or filed
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.

     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 Agency, 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.

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,

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

representatives to hold in confidence all such information except to the extent
disclosure may be required by law (and all reasonable applications for
confidential treatment are unavailing) and except to the extent that the
Indenture Trustee or the Securities Administrator may reasonably determine that

     MERRILL LYNCH MORTGAGE INVESTORS TRUST, SERIES 2005-A9 (the "Issuer"), a
Delaware statutory trust, for value received, hereby promises to pay to [_____]
or registered assigns, the principal sum of [_____ DOLLARS ($_____)] in monthly
installments on the twenty-fifth day of each month or, if such day is not a

commencing in January 2006 and ending on or before the Payment Date occurring in
November 2036 (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 Loan
Asset-Backed Notes, Series 2005-A9 (the "Notes"), issued under an Indenture
dated as of December 22, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, N.A., as Securities Administrator (the "Securities Administrator") and
Wachovia Bank, National Association, 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, minus (i) all amounts distributed in
respect of principal with respect to such Class of Notes and (ii) the aggregate
amount of any reductions in the Note Principal Balance thereof deemed to have
occurred in connection with allocations of Realized Losses on all prior Payment
Dates in accordance with the Indenture, taking account of its applicable Loss
Allocation Limitation, plus (iii) any Subsequent Recoveries allocated thereto.

     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
[1-A-1], [2-A-1A], [2-A-1B], [2-A-1C], [2-A-1D], [2-A-1E], [2-A-2], [3-A-1],
[4-A-1], [5-

                                      A-1-2

<PAGE>

A-1] 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.

     The Mortgage Loans are subject to purchase 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 10% 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 [1-A-1], [2-A-1A],
[2-A-1B], [2-A-1C], [2-A-1D], [2-A-1E], [2-A-2], [3-A-1], [4-A-1], [5-A-1]
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 Owner Trustee, the Indenture Trustee, the Depositor,
the Seller, the Master Servicer, the Securities Administrator 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 [1-A-1], [2-A-1A],
[2-A-1B], [2-A-1C], [2-A-1D], [2-A-1E], [2-A-2], [3-A-1], [4-A-1], [5-A-1] Notes
pursuant to the Indenture and the rights conveyed to 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 reductions in the principal amount of a Note
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 4.02 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

                                      A-1-3

<PAGE>

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 this Note, 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.

     The failure to pay any Net Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     Each Investor in this Note or any interest herein will be deemed to have
represented and agreed to either (I) that it is not an employee benefit plan or
arrangement subject to Title I of ERISA, a plan subject to Section 4975 of the
Code or a plan subject to any provisions under Similar Law and it is not
directly or indirectly acquiring this Note for, on behalf of or with any assets
of any such plan or (II) that It is a person described in clause (I) and its
acquisition and holding of this Note, or any interest herein, will not
constitute or result in a non-exempt prohibited transaction under ERISA or the
Code, or a violation of Similar Law, and will not subject the Issuer, the
Seller, the Owner Trustee, the Indenture Trustee, the Securities Administrator,
the Note Registrar, the Master Servicer or any Servicer to any obligation in
addition to those undertaken by the Issuer, the Indenture Trustee or the Owner
Trustee 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 then outstanding
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

consent of the Holder of each Note. 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, following prior notice to
the Rating Agencies, 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

the Indenture and subject to certain limitations therein set forth. The Notes
are exchangeable for a like aggregate then outstanding 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.

provided in the Basic Documents, neither the Owner Trustee in its individual
capacity, nor any of its respective partners, beneficiaries, agents, officers,
directors, employees, or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or
interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this Note, it being expressly
understood that said covenants, obligations and indemnifications have been made
solely by the Trust to the extent of the assets of the Trust. The holder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Trust Estate for any and all liabilities, obligations and
undertakings contained in this Note.

     AS PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS

     MERRILL LYNCH MORTGAGE INVESTORS TRUST, SERIES 2005-A9 (the "Issuer"), a
Delaware statutory trust, for value received, hereby promises to pay to [_____]
or registered assigns, the principal sum of [_____ DOLLARS ($_____)] 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 January 2006 and ending on or before the Payment Date occurring in
November 2036 (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 Loan
Asset-Backed Notes, Series 2005-A9 (the "Notes"), issued under an Indenture,
dated as of December 22, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, N.A., as Securities Administrator (the "Securities Administrator") and
Wachovia Bank, National Association, as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee), 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, minus (i) all amounts distributed in
respect of principal with respect to such Class of Notes, (ii) the aggregate
amount of any reductions in the Note Principal Balance thereof deemed to have
occurred in connection with allocations of Realized Losses on all prior Payment
Dates in accordance with the Indenture, taking account of its applicable Loss
Allocation Limitation, and (iii) such Class's pro rata share, if any, of the
applicable Subordinate Writedown Amount for previous Payment Dates, plus (iv)
any Subsequent Recoveries allocated thereto.

     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

                                     A-2-2

<PAGE>

Class [1][3][5]-A-2 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.

     The Mortgage Loans are subject to purchase 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 10% 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 [1][3][5]-A-2
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 Owner Trustee, the Indenture Trustee, the Depositor,
the Seller, the Master Servicer, the Securities Administrator 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 [1][3][5]-A-2 Notes
pursuant to the Indenture and the rights conveyed to 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 reductions in the principal amount of a Note
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 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 this Note,

                                     A-2-3

<PAGE>

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.

     The failure to pay any Net Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     No transfer, sale, pledge or other disposition of this Note or interest
herein shall be made unless that transfer, sale, pledge or other disposition is
exempt from the registration and/or qualification requirements of the Securities
Act and any applicable state securities laws, or is otherwise made in accordance
with the Securities Act and such state securities laws. If a transfer of this
Note is to be made without registration under the Securities Act (other than in
connection with the initial issuance thereof or a transfer thereof by the
Depositor or one of its Affiliates), then the Note Registrar shall refuse to
register such transfer unless (i) it receives (and upon receipt, may
conclusively rely upon) a certificate substantially in the form attached as
Exhibit C to the Indenture or (ii) it receives a written Opinion of Counsel
acceptable to and in form and substance satisfactory to the Note Registrar and
the Indenture Trustee and the transferee executes a representation letter
substantially in the form of Exhibit D attached to the Indenture, and transferor
executes a representation letter substantially in the form of Exhibit E attached
to the Indenture, each acceptable to and in form and substance satisfactory to
the Note Registrar and the Indenture Trustee. None of the Issuer, the Depositor,
the Indenture Trustee or the Note Registrar is obligated to register or qualify
any Notes under the Securities Act or any other securities law or to take any
action not otherwise required under the Indenture to permit the transfer of this
Note or interest herein without registration or qualification. Any Noteholder
desiring to effect a transfer of this Note or interest herein shall, and does
hereby agree to, indemnify the Issuer, the Depositor, the Owner Trustee, the
Indenture Trustee and the Note Registrar against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

     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 then outstanding
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 nor 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 each Class of Notes affected
thereby. The Indenture also contains provisions permitting the Holders of Notes
representing not less than a majority of the aggregate Note Principal Balance of
the Notes, to 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 of the Indenture
which cannot be modified or amended without the consent of the Holder of each
Note. 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, following prior notice to the Rating Agencies, to
amend or waive certain terms and conditions set forth in the Indenture without
the consent of the Holders of the Notes issued thereunder.

     The Notes are exchangeable for a like aggregate then outstanding 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

     Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither the Owner Trustee in its individual
capacity, nor any of its respective partners, beneficiaries, agents, officers,
directors, employees, or successors or assigns, shall be personally liable for,

interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this Note, it being expressly

     MERRILL LYNCH MORTGAGE INVESTORS TRUST, SERIES 2005-A9 (the "Issuer"), a
Delaware statutory trust, for value received, hereby promises to pay to [_____]
or registered assigns, the principal sum of [_____ DOLLARS ($_____)] 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 January 2006 and ending on or before the Payment Date occurring in
November 2036 (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 Loan
Asset-Backed Notes, Series 2005-A9 (the "Notes"), issued under an Indenture,
dated as of December 22, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, N.A., as Securities Administrator (the "Securities Administrator"), and
Wachovia Bank, National Association, as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee), 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, minus (i) all amounts distributed in
respect of principal with respect to such Class of Notes, (ii) the aggregate
amount of any reductions in the Note Principal Balance thereof deemed to have
occurred in connection with allocations of Realized Losses on all prior Payment
Dates in accordance with the Indenture, taking account of its applicable Loss
Allocation Limitation, and (iii) such Class's pro rata share, if any, of the
applicable Subordinate Writedown Amount for previous Payment Dates, plus (iv)
any Subsequent Recoveries allocated thereto.

     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

                                     A-3-3

<PAGE>

Class [4-A-2], [M-[1][2][3]] 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.

     The Mortgage Loans are subject to purchase 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 10% 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 [4-A-2],
[M-[1][2][3]] 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 Owner Trustee, the Indenture
Trustee, the Depositor, the Seller, the Master Servicer, the Securities
Administrator 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 [4-A-2], [M-[1][2][3]] Notes pursuant to the Indenture and the rights
conveyed to 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 reductions in the principal amount of a Note
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 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

                                     A-3-4

<PAGE>

Holder of this Note will be equal to the sum of the unpaid Note Principal
Balance of this Note, 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.

     The failure to pay any Net Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     No transfer, sale, pledge or other disposition of this Note or interest
herein shall be made unless that transfer, sale, pledge or other disposition is
exempt from the registration and/or qualification requirements of the Securities
Act and any applicable state securities laws, or is otherwise made in accordance
with the Securities Act and such state securities laws. If a transfer of this
Note is to be made without registration under the Securities Act (other than in
connection with the initial issuance thereof or a transfer thereof by the
Depositor or one of its Affiliates), then the Note Registrar shall refuse to
register such transfer unless (i) it receives (and upon receipt, may
conclusively rely upon) a certificate substantially in the form attached as
Exhibit C to the Indenture or (ii) it receives a written Opinion of Counsel
acceptable to and in form and substance satisfactory to the Note Registrar and
the Indenture Trustee and the transferee executes a representation letter
substantially in the form of Exhibit D attached to the Indenture, and transferor
executes a representation letter substantially in the form of Exhibit E attached
to the Indenture, each acceptable to and in form and substance satisfactory to
the Note Registrar and the Indenture Trustee. None of the Issuer, the Depositor,
the Indenture Trustee or the Note Registrar is obligated to register or qualify
any Notes under the Securities Act or any other securities law or to take any
action not otherwise required under the Indenture to permit the transfer of this
Note or interest herein without registration or qualification. Any Noteholder
desiring to effect a transfer of this Note or interest herein shall, and does
hereby agree to, indemnify the Issuer, the Depositor, the Owner Trustee, the
Indenture Trustee and the Note Registrar against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

     No transfer of this Class [4-A-2], [M-[1][2][3]] Note (other than any Class
[4-A-2], [M-[1][2][3]] Note with respect to which a "will be debt" opinion has
been rendered by nationally recognized tax counsel and furnished to the
Securities Administrator) or any interest therein shall be made to any Person,
and the Note Registrar shall refuse to register any such transfer, unless the
transferee shall have delivered to the Owner Trustee, the Note Registrar, the
Securities Administrator and the Indenture Trustee a certificate certifying that
(i) it is a real estate investment trust ("REIT") within the meaning of Section
856(a) of the Code, a qualified REIT subsidiary ("QRS") within the meaning of
Section 856(i) of the Code, or an entity disregarded as an entity separate from
a REIT or a QRS and (ii) following the transfer, 100% of the Subordinate Notes
and Trust Certificates (other than any Subordinate Notes that are characterized
as indebtedness for federal income tax purposes) will be owned by a REIT,
directly or indirectly through one or more qualified QRSs of such single REIT or
one or more entities disregarded as entities separate from such REIT or such
QRSs; provided that (x) this Class [4]-[A][M]-[1][2][3] Note may be pledged to
secure indebtedness and may be the subject of repurchase agreements treated as
secured indebtedness for federal income tax purposes, and (y) this Class
[4-A-2], [M-

                                     A-3-5

<PAGE>

[1][2][3]] Note may be transferred by the related lender under any such related
loan agreement or repurchase agreement upon a default under any such
indebtedness, in which case the transferor shall deliver to the Note Registrar
and the Securities Administrator a certificate certifying to such effect.

     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 then outstanding
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 nor 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 each Class of Notes affected
thereby. The Indenture also contains provisions permitting the Holders of Notes
representing not less than a majority of the aggregate Note Principal Balance of
the Notes, to 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 of the Indenture
which cannot be modified or amended without the consent of the Holder of each
Note. 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, following prior notice to the Rating Agencies, to
amend or waive certain terms and conditions set forth in the Indenture without
the consent of the Holders of the Notes issued thereunder.

     The Notes are exchangeable for a like aggregate then outstanding 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.

     Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither the Owner Trustee in its individual
capacity, nor any of its respective partners, beneficiaries, agents, officers,
directors, employees, or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or

                                     A-3-6

interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this Note, it being expressly
understood that said covenants, obligations and indemnifications have been made
solely by the Trust to the extent of the assets of the Trust. The holder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Trust Estate for any and all liabilities, obligations and
undertakings contained in this Note.

     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.

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, minus (i) all amounts distributed in
respect of principal with respect to such Class of Notes, (ii) the aggregate
amount of any reductions in the Note Principal Balance thereof deemed to have
occurred in connection with allocations of Realized Losses on all prior Payment
Dates in accordance with the Indenture, taking account of its applicable Loss
Allocation Limitation, and (iii) such Class's pro rata share, if any, of the
applicable Subordinate Writedown Amount for previous Payment Dates, plus (iv)
any Subsequent Recoveries allocated thereto.

     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

                                     A-4-3

<PAGE>

Class B-[1][2][3] 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.

     The Mortgage Loans are subject to purchase 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 10% 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 B-[1][2][3] 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 Owner Trustee, the Indenture Trustee, the Depositor, the
Seller, the Master Servicer, the Securities Administrator 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-[1][2][3] Notes pursuant
to the Indenture and the rights conveyed to 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 reductions in the principal amount of a Note
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 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 this Note,

                                     A-4-4

<PAGE>

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.

     The failure to pay any Net Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     No transfer, sale, pledge or other disposition of this Note or interest
herein shall be made unless that transfer, sale, pledge or other disposition is
exempt from the registration and/or qualification requirements of the Securities
Act and any applicable state securities laws, or is otherwise made in accordance
with the Securities Act and such state securities laws. If a transfer of this
Note is to be made without registration under the Securities Act (other than in
connection with the initial issuance thereof or a transfer thereof by the
Depositor or one of its Affiliates), then the Note Registrar shall refuse to
register such transfer unless (i) it receives (and upon receipt, may
conclusively rely upon) a certificate substantially in the form attached as
Exhibit C to the Indenture or (ii) it receives a written Opinion of Counsel
acceptable to and in form and substance satisfactory to the Note Registrar and
the Indenture Trustee and the transferee executes a representation letter
substantially in the form of Exhibit D attached to the Indenture, and transferor
executes a representation letter substantially in the form of Exhibit E attached
to the Indenture, each acceptable to and in form and substance satisfactory to
the Note Registrar and the Indenture Trustee. None of the Issuer, the Depositor,
the Indenture Trustee or the Note Registrar is obligated to register or qualify
any Notes under the Securities Act or any other securities law or to take any
action not otherwise required under the Indenture to permit the transfer of this
Note or interest herein without registration or qualification. Any Noteholder
desiring to effect a transfer of this Note or interest herein shall, and does
hereby agree to, indemnify the Issuer, the Depositor, the Owner Trustee, the
Indenture Trustee and the Note Registrar against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

     Each investor in this Note or any interest herein will be deemed to have
represented and agreed either that it (A) is not an employee benefit plan or
arrangement subject to Title I of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), or a plan subject to Section 4975 of the Internal
Revenue Code of 1986, as amended (the "Code"), and it is not directly or
indirectly acquiring this Note for, on behalf of or with any assets of any such
plan, or (B) is a plan subject to any provisions under any federal, state,
local, non-U.S. or other laws or regulations that are substantively similar to
Title I of ERISA or Section 4975 of the Code ("Similar Law"), and the
acquisition and holding of this Note by such plan subject to Similar Law will
not constitute or result in a violation of Similar Law, or subject the Issuer,
the Seller, the Depositor, the Owner Trustee, the Indenture Trustee, the
Securities Administrator, the Note Registrar, the Master Servicer, or any
Servicer to any obligation in addition to those undertaken by the Issuer, the
Seller, the Depositor, the Indenture Trustee, the Owner Trustee, the Securities
Administrator, the Note Registrar, the Master Servicer, or any Servicer in the
Indenture. If the Note is not a Definitive Note, the investor is deemed to have
made the representation in (A) or (B) above.

     No transfer of this Class B-[1][2][3] Note (other than any Class
B-[1][2][3] Note with respect to which a "will be debt" opinion has been
rendered by nationally recognized tax counsel and furnished to the Securities
Administrator) or any interest therein shall be made to any Person, and the Note
Registrar shall refuse to register any such transfer, unless the transferee
shall have delivered to the Owner Trustee, the Note Registrar, the Securities
Administrator and the Indenture Trustee a certificate certifying that (i) it is
a real estate investment trust ("REIT") within the meaning of Section 856(a) of
the Code, a qualified REIT subsidiary ("QRS") within the meaning of Section
856(i) of the Code, or an entity disregarded as an entity separate from a REIT
or a QRS and (ii) following the transfer, 100% of the Subordinate Notes and
Trust Certificates (other than any Subordinate Notes that are characterized as
indebtedness for federal income tax purposes) will be owned by a REIT, directly
or indirectly through one or more qualified QRSs of such single REIT or one or
more entities disregarded as entities separate from such REIT or such QRSs;
provided that (x) this Class B-[1][2][3] Note may be pledged to secure
indebtedness and may be the subject of repurchase agreements treated as secured
indebtedness for federal income tax purposes, and (y) this Class B-[1][2][3]
Note may be transferred by the related lender under any such related loan
agreement or repurchase agreement upon a default under any such indebtedness, in
which case the transferor shall deliver to the Note Registrar and the Securities
Administrator a certificate certifying to such effect.

     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 then outstanding
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 nor 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 each Class of Notes affected
thereby. The Indenture also contains provisions permitting the Holders of Notes
representing not less than a majority of the aggregate Note Principal Balance of
the Notes, to 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 of the Indenture
which cannot be modified or amended without the consent of the Holder of each
Note. 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

                                     A-4-6

<PAGE>

Issuer, the Indenture Trustee and the Securities Administrator, following prior
notice to the Rating Agencies, to amend or waive certain terms and conditions
set forth in the Indenture without the consent of the Holders of the Notes
issued thereunder.

     The Notes are exchangeable for a like aggregate then outstanding 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.

     Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither the Owner Trustee in its individual
capacity, nor any of its respective partners, beneficiaries, agents, officers,
directors, employees, or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or
interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this Note, it being expressly
understood that said covenants, obligations and indemnifications have been made
solely by the Trust to the extent of the assets of the Trust. The holder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Trust Estate for any and all liabilities, obligations and
undertakings contained in this Note.

     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.

<TABLE>
<S>      <C>                             <C>

</TABLE>

     The undersigned seller, as registered holder (the "Seller"), intends to
transfer the Rule 144A Securities described above to the undersigned buyer (the
"Buyer").

          1. In connection with such transfer and in accordance with the
agreements pursuant to which the Rule 144A Securities were issued, the Seller
hereby certifies the following facts: Neither the Seller nor anyone acting on
its behalf has offered, transferred, pledged, sold or otherwise disposed of the
Rule 144A Securities, any interest in the Rule 144A Securities or any other
similar security to, or solicited any offer to buy or accept a transfer, pledge
or other disposition of the Rule 144A Securities, any interest in the Rule 144A
Securities or any other similar security from, or otherwise approached or
negotiated with respect to the Rule 144A Securities, any interest in the Rule
144A Securities or any other similar security with, any person in any manner, or
made any general solicitation by means of general advertising or in any other
manner, or taken any other action, that would constitute a distribution of the
Rule 144A Securities under the Securities Act of 1933, as amended (the "1933
Act"), or that would render the disposition of the Rule 144A Securities a
violation of Section 5 of the 1933 Act or require registration pursuant thereto,
and that the Seller has not offered the Rule 144A Securities to any person other
than the Buyer or another "qualified institutional buyer" as defined in Rule
144A under the 1933 Act.

          2. The Buyer warrants and represents to, and covenants with, the
Indenture Trustee pursuant to Section 4.02 of the Indenture (the "Indenture"),
dated as of December 22, 2005, among Merrill Lynch Mortgage Investors Trust,
Series 2005-A9, as Issuer, and Wells Fargo Bank, N.A., as Securities
Administrator and Wachovia Bank, National Association, as Indenture Trustee, as

<PAGE>

          c. The Buyer has been furnished with all information regarding the
     Rule 144A Securities that it has requested from the Seller, the Indenture
     Trustee, the Owner Trustee or the Master Servicer.

          d. Neither the Buyer nor anyone acting on its behalf has offered,
     transferred, pledged, sold or otherwise disposed of the Rule 144A
     Securities, any interest in the Rule 144A Securities or any other similar
     security to, or solicited any offer to buy or accept a transfer, pledge or
     other disposition of the Rule 144A Securities, any interest in the Rule
     144A Securities or any other similar security from, or otherwise approached
     or negotiated with respect to the Rule 144A Securities, any interest in the
     Rule 144A Securities or any other similar security with, any person in any
     manner, or made any general solicitation by means of general advertising or
     in any other manner, or taken any other action, that would constitute a
     distribution of the Rule 144A Securities under the 1933 Act or that would
     render the disposition of the Rule 144A Securities a violation of Section 5
     of the 1933 Act or require registration pursuant thereto, nor will it act,
     nor has it authorized or will it authorize any person to act, in such
     manner with respect to the Rule 144A Securities.

          e. The Buyer is a "qualified institutional buyer" as that term is
     defined in Rule 144A under the 1933 Act and has completed either of the
     forms of certification to that effect attached hereto as Annex 1 or Annex
     2. The Buyer is aware that the sale to it is being made in reliance on Rule
     144A. The Buyer is acquiring the Rule 144A Securities for its own account
     or the accounts of other qualified institutional buyers, understands that
     such Rule 144A Securities may be resold, pledged or transferred only (i) to
     a person reasonably believed to be a qualified institutional buyer that
     purchases for its own account or for the account of a qualified
     institutional buyer to whom notice is given that the resale, pledge or
     transfer is being made in reliance on Rule 144A, or (ii) pursuant to
     another exemption from registration under the 1933 Act.

          3. With respect to the Class B Notes, the Buyer warrants and
represents to, and covenants with, the Seller, the Indenture Trustee, Owner
Trustee, the Certificate Registrar, Master Servicer and the Depositor that

and it is not directly or indirectly acquiring the Class B Note for, on behalf
of or with any assets of any such plan, or (B) it is a plan subject to any
provisions under any federal, state, local, non-U.S. or other laws or
regulations that are substantively similar to Title I of ERISA or Section 4975
of the Code ("Similar Law"), and the acquisition and holding of the Class B Note
by such plan subject to Similar Law will not constitute or result in a violation
of Similar Law, or subject the Issuer, the Seller, the Depositor, the Owner
Trustee, the Indenture Trustee, the Securities Administrator, the Note
Registrar, the Master Servicer, or any Servicer to any obligation in addition to
those undertaken by the Issuer, the Seller, the Depositor, the Indenture
Trustee, the Owner Trustee, the Securities Administrator, the Note Registrar,
the Master Servicer, or any Servicer in the Indenture.

          4. This document may be executed in one or more counterparts and by
the different parties hereto on separate counterparts, each of which, when so
executed, shall be deemed to be an original; such counterparts, together, shall
constitute one and the same document.

Re:  Proposed Transfer of Class [1][2][3][4][5]-A Notes,
     Merrill Lynch Mortgage Investors Trust, Series 2005-A9

Ladies and Gentlemen:

     This certification is being made by [____________________] (the
"Transferor") in connection with the proposed sale ("Transfer") to
[_____________________] (the "Transferee") of the Class [1][2][3][4][5]-A Note
(the "Senior Note") issued pursuant to an indenture, dated as of December 22,
2005 (the "Indenture") among Merrill Lynch Mortgage Investors Trust, Series
2005-A9, as issuer (the "Issuer"), Wells Fargo Bank, N.A., as securities
administrator (the "Securities Administrator") and Wachovia Bank, National
Association, as indenture trustee (the "Indenture Trustee"). Capitalized terms
used but not defined herein have the meanings assigned to them in Appendix A to
the Indenture. The Transferor hereby certifies, represents and warrants to, and
covenants with, the Issuer, the Securities Administrator and the Indenture
Trustee that:

     (1) Based on consultation with counsel, no adverse changes have been made
to (or that would adversely affect the application of) the Closing Date Legal
Authorities;

     (2) No modifications have been made to the Indenture as of the date hereof
(other than any modification for which an Opinion of Counsel was rendered to the
effect that such modification does not materially and adversely affect the
transfer restrictions with respect to the Senior Notes set forth in Section 4.02
of the Indenture);

     (3) The Rating Agencies' respective ratings of the Senior Notes as of the
date hereof are not lower than the ratings on such Senior Notes as of the
Closing Date; and

     (4) the sum of (x) the aggregate Note Principal Balance of the Subordinate
Notes as of the Payment Date on or immediately preceding the date hereof and (y)
the present value as of the date hereof of the expected total cashflow on the
Owner Trust Certificates on future Distribution Dates plus the expected interest
cashflow on the Subordinate Notes on future Distribution Dates plus the expected
total cashflow on the Owner Trust Certificates on future Distribution Dates

                                      I-1

<PAGE>

(such expected cashflow in each case calculated assuming no Realized Losses on
the Mortgage Loans, a prepayment assumption equal to that used in connection
with the Transfer of such Senior Notes, and the forward LIBOR curve in effect on
the date hereof), discounted at ten (10%) percent per annum, is at least equal
to 4.0% of the aggregate Outstanding Principal Balance of the Outstanding
Mortgage Loans as of the date hereof.

     agreements, that are necessary, suitable or convenient to accomplish the
     foregoing or are incidental thereto or connected therewith; and

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

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

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

     Section 2.06. Declaration of Trust. The Owner Trustee hereby declares that
it shall hold the Owner Trust Estate in trust upon and subject to the conditions
set forth herein for the use and benefit of the Certificateholders, subject to
the obligations of the Trust under the Basic Documents. It is the intention of
the parties hereto that the Trust constitute a "statutory trust" under the
Statutory Trust Statute and that this Trust Agreement constitute the governing
instrument of such statutory trust. It is the intention of the parties hereto
that, for federal and state income and state and local franchise tax purposes,
(A) the Trust shall be treated as (1) disregarded as an entity separate from its
owner or (2) a qualified REIT subsidiary within the meaning of Section 856(i) of
the Code ("QRS"), for so long as 100% of the Certificates, the Class 4-A-2 Notes
and the Subordinate Notes (other than any of the Class 4-A-2 Notes and
Subordinate Notes with respect to which a "will be debt" opinion has been
rendered by nationally recognized tax counsel and furnished to the Securities
Administrator) are held by a single entity which is classified as a real estate
investment trust within the meaning of Section 856(a) of the Code ("REIT"),
directly or indirectly through one or more QRSs of such REIT or one or more
entities disregarded as entities separate from such REIT or such QRSs, and (B)
the Class 1-A, Class 2-A, Class 3-A, Class 4-A-1 and Class 5-A Notes shall be
characterized as indebtedness to a Noteholder other than a Noteholder which owns
100% of the Certificates, the Class 4-A-2 Notes and the Subordinate Notes (other
than any Subordinate Notes that are characterized as indebtedness for federal
income tax purposes) if the Trust is disregarded as an entity separate from such
Noteholder or is treated as a QRS of such Noteholder, and the provisions of this
Agreement shall be interpreted to further this intention. Except as otherwise
provided in this Trust Agreement, the rights of the Certificateholders will be
those of equity owners of the Trust. Effective as of the date hereof, the Owner
Trustee shall have all rights, powers and duties set forth herein and in the
Statutory Trust Statute with respect to accomplishing the purposes of the Trust.

     Section 2.07. Liability of the Holders of the Certificates. The Holders of
the Certificates shall be jointly and severally liable directly to and shall
indemnify any injured party for all losses, claims, damages, liabilities and
expenses of the Trust and the Owner Trustee (including Expenses, to the extent
not paid out of the Owner Trust Estate) to the extent that the Holders of the
Certificates would be liable if the Trust were a corporation, and the Holders of
the Certificates were common stockholders in the corporation, under Delaware
corporate law; provided, however, that the Holders of the Certificates shall not
be liable for payments required to be made on the Notes or the Certificates, or
for any losses incurred by a Certificateholder in the capacity of an investor in
the Certificates or a Noteholder in the capacity of an investor in the

                                       4

<PAGE>

Notes. The Holders of the Certificates shall be liable for and shall promptly
pay any entity level taxes imposed on the Trust. In addition, any third party
creditors of the Trust (other than in connection with the obligations described
in the second preceding sentence for which the Holders of the Certificates shall
not be liable) shall be deemed third party beneficiaries of this paragraph. The
obligations of the Holders of the Certificates under this paragraph shall be
evidenced by the Certificates.

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

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

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

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

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

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

                                       5

<PAGE>

          (iv) The consummation of the transactions contemplated by this Trust
     Agreement and the fulfillment of the terms hereof do not conflict with,
     result in any breach of any of the terms and provisions of, or constitute
     (with or without notice or lapse of time) a default under, the articles of
     incorporation or by-laws of the Depositor, or any indenture, agreement or
     other instrument to which the Depositor is a party or by which it is bound;
     nor result in the creation or imposition of any Lien upon any of its
     properties pursuant to the terms of any such indenture, agreement or other
     instrument (other than pursuant to the Basic Documents); nor violate any
     law or, to the best of the Depositor's knowledge, any order, rule or
     regulation applicable to the Depositor of any court or of any federal or
     state regulatory body, administrative agency or other governmental
     instrumentality having jurisdiction over the Depositor or its properties.

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

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

                        Conveyance of the Mortgage Loans;
                                  Certificates

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

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

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

     Section 3.03. Authentication of Certificates. The Certificate Registrar
shall cause all Certificates issued hereunder to be executed, authenticated and
delivered to or upon the written order of the Depositor, signed by its chairman
of the board, its president or any vice president, without further corporate
action by the Depositor, in the authorized denomination. The Certificate shall
entitle its holder to any benefit under this Owner Trust Agreement or be valid
for any purpose unless there shall appear on the Certificates a certificate of
authentication substantially in the form set forth in Exhibit A, executed by the
Certificate Registrar or by an authenticating agent of the Issuer by manual
signature; such authentication shall constitute conclusive evidence that the
Certificate shall have been duly authenticated and delivered hereunder. The
Certificates shall be dated the date of its authentication.

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

                                       7

<PAGE>

the Certificate Registrar resigns or is removed, the Depositor shall appoint a
successor Certificate Registrar.

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

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

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

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

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

                                       8

<PAGE>

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

     No transfer of Certificates or any interest therein shall be made to an
employee benefit plan or arrangement subject to Title I of ERISA, a plan subject
to Section 4975 of the Code, or a plan subject to any provisions under any
federal, state, local, non-U.S. or other laws or regulations that are
substantively similar to the foregoing provisions of ERISA or the Code
(collectively, a "Plan"), or any Person directly or indirectly acquiring the
Certificates for, on behalf of or with any assets of any such Plan.

     No transfer, sale, pledge or other disposition of a Certificate or any
interest therein shall be made, and the Certificate Registrar shall refuse to
register any such transfer, sale, pledge or other disposition, unless (A) the
transferee shall have delivered to the Certificate Registrar, the Owner Trustee,
the Securities Administrator and the Indenture Trustee a certificate
substantially in the form attached hereto as Exhibit H certifying that (i) it is
a REIT within the meaning of Section 856(a) of the Code or a QRS within the
meaning of Section 856(i) of the Code or an entity disregarded as an entity
separate from a REIT or a QRS and (ii) following the transfer, 100% of the
Certificates, the Class 4-A-2 Notes and the Subordinate Notes (other than any of
the Class 4-A-2 Notes or Subordinate Notes with respect to which a "will be
debt" opinion has been rendered by nationally recognized tax counsel and
furnished to the Securities Administrator) will be owned by a single REIT,
directly or indirectly through one or more QRSs of such REIT or one or more
entities disregarded as entities separate from such REIT or such QRSs and (B)
the proposed transferor delivers to the Owner Trustee, the Certificate
Registrar, the Securities Administrator and the Indenture Trustee an Opinion of
Counsel, rendered by a law firm generally recognized to be qualified to opine
concerning the tax aspects of asset securitization, to the effect that,
following such transfer, the Trust will continue to be treated for federal
income tax purposes as a QRS; provided that, notwithstanding the foregoing, (x)
any Certificates may be pledged to secure indebtedness and may be the subject of
repurchase agreements treated by the Issuer as secured indebtedness for federal
income tax purposes, and (y) any Certificates may be transferred by the related
lender under any such related loan agreement or repurchase agreement upon a
default under any such indebtedness, in which case the transferor shall deliver
to the Certificate Registrar, the Securities Administrator, the Owner Trustee
and the Indenture Trustee a certificate substantially in the form attached
hereto as Exhibit I certifying to such effect.

                                       9

<PAGE>

Notwithstanding the foregoing, the provisions of this paragraph shall not apply
to the initial transfer of the Certificates to the Depositor or any Affiliate
thereof.

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

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

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

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

     Section 3.09. Certificate Paying Agent. (a) The Certificate Paying Agent
shall make distributions to Certificateholders from the Certificate Distribution
Account on behalf of the Trust in accordance with the provisions of the
Certificates and Section 5.01 hereof from payments remitted to the Certificate
Paying Agent by the Securities Administrator pursuant to Section 3.03 of the
Indenture. The Trust hereby appoints the Securities Administrator as Certificate
Paying Agent and the Securities Administrator hereby accepts such appointment
and further agrees that it will be bound by the provisions of this Trust
Agreement relating to the Certificate Paying Agent and shall:

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

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

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

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

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

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

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

                                       11

<PAGE>

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

     (c) The Certificate Paying Agent shall establish and maintain with itself a
trust account (the "Certificate Distribution Account") in which the Certificate
Paying Agent shall deposit, on the same day as it is received from the
Securities Administrator, each remittance received by the Certificate Paying
Agent with respect to payments made pursuant to the Indenture. The Certificate
Paying Agent shall make all distributions to Certificates, from moneys on
deposit in the Certificate Distribution Account, in accordance with Section 5.01
hereof. The funds in the Certificate Distribution Account shall be held
uninvested.

                      Authority and Duties of Owner Trustee

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

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

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

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

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

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

perfect or maintain the perfection of any security interest or lien granted to
it hereunder or to prepare or file any Securities and Exchange Commission filing
for the Trust or to record this Trust Agreement or any Basic Document. The Owner
Trustee nevertheless agrees that it will, at its own cost and expense, promptly
take all action as may be necessary to discharge any liens on any part of the
Owner Trust Estate that result from actions by, or claims against, the Owner
Trustee that are not related to the ownership or the administration of the Owner
Trust Estate.

purposes of the Trust set forth in Section 2.03, (y) that, to the actual
knowledge of the Owner Trustee based on an Opinion of Counsel rendered by a law
firm generally recognized to be qualified to opine concerning the tax aspects of
asset securitization, would result in the Trust becoming taxable as a
corporation for federal income tax purposes or failing to maintain its status as
a disregarded entity or a QRS (as defined above) or (z) would result in the
amendment or modification of the Basic Documents or this Trust Agreement. The
Certificateholders shall not direct the Owner Trustee to take action that would
violate the provisions of this Section 4.05.

     (b) Subject to the proviso in the last paragraph of Section 3.04 hereof,
the Owner Trustee shall not convey or transfer any of the Trust's properties or
assets, including those included in the Owner Trust Estate, to any person unless
(a) it shall have received an Opinion of Counsel rendered by a law firm
generally recognized to be qualified to opine concerning the tax aspects of
asset securitization to the effect that such transaction will not have any
material adverse tax consequence to the Trust or any Certificateholder and (b)
such conveyance or transfer shall not violate the provisions of Section 3.12(b)
of the Indenture.

     Section 4.06. Prior Notice to Certificateholders with Respect to Certain

Trust (unless such amendment is required to be filed under the Statutory Trust
Statute);

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

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

     (e) the appointment pursuant to the Indenture of a successor Note
Registrar, Paying Agent or Indenture Trustee or pursuant to this Trust Agreement
of a successor Certificate Registrar or Certificate Paying Agent or the consent
to the assignment by the Note Registrar, Paying Agent, Indenture Trustee,
Certificate Registrar or Certificate Paying Agent of its obligations under the
Indenture or this Trust Agreement, as applicable.

     Section 4.07. Action by Certificateholders with Respect to Certain Matters.
The Owner Trustee shall not have the power, except upon the direction of the

such Certificateholder reasonably believes that the Trust is insolvent. This
paragraph shall survive for one year following termination of this Trust
Agreement.

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

     Section 4.10. Majority Control. Except as expressly provided herein, any
action that may be taken by the Certificateholders under this Trust Agreement

     Section 4.11. Optional Redemption. Upon receipt of written instructions
provided to the Securities Administrator by the Majority Certificateholder, the
Issuer shall redeem the Notes in accordance with Section 8.06 of the Indenture

of the Issuer to effect the foregoing, provided that such Holder shall deposit
with the Securities Administrator an amount equal to the aggregate redemption
price specified under Section 8.06 of the Indenture. The Issuer shall not have

                           Application of Trust Funds

     Section 5.01. Distributions. (a) On each Payment Date, the Certificate
Paying Agent shall in accordance with the directions of the Securities
Administrator given pursuant to the Indenture distribute to the
Certificateholders, on a pro rata basis based on the Certificate Percentage
Interests thereof, all funds on deposit in the Certificate Distribution Account
and available therefor (as provided in Section 3.03 of the Indenture) for such
Payment Date as reduced by any amount owing to the Owner Trustee hereunder and
any Expenses of the Trust remaining unpaid.

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

     (c) Distributions to Certificateholders shall be subordinated to the
creditors of the Trust, including the Noteholders.

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

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

                                       17

<PAGE>

cause to be collected any withholding tax as described in and in accordance with
Section 5.01 of this Trust Agreement with respect to income or distributions to
Certificateholders and prepare or cause to be prepared the appropriate forms
relating thereto; provided, however, that the Seller shall not be required to
(x) prepare and file corporation tax returns on behalf of the Trust, (y)
calculate and/or report any "excess inclusions" with respect to the
Certificates, or (z) compute the Issuer's gross income; and provided further
that the Seller shall not be required to prepare and file partnership tax
returns or any other tax returns on behalf of the Issuer or do any additional
tax work caused by any change in the tax treatment of the Notes or Trust from
the treatment contemplated hereunder, unless the Seller receives (i) an Opinion
of Counsel reasonably satisfactory to it (which shall not be at the Seller's
expense, but shall be at the expense of the Depositor or other party furnishing
such opinion) as to the necessity of such filings or work, and (ii) reasonable
additional compensation for the preparation and filing of such additional
returns or any such additional tax work. The Issuer hereby grants permission to
the Seller to sign, to the extent permitted by law, all tax and information
returns prepared by the Seller pursuant to this Section 5.03 at the request of
the Seller, and in doing so the Owner Trustee and the Certificateholders shall
rely entirely upon, and shall have no liability for information or calculations
provided by, the Seller.

     Section 5.04. Statements to Certificateholders. On each Payment Date, the
Securities Administrator shall make available to each Certificateholder the
statement or statements provided to the Owner Trustee by the Securities
Administrator pursuant to Section 7.04 of the Indenture with respect to such
Payment Date.

request, order or direction of any of the Certificateholders, unless such
Certificateholders have offered to the Owner Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities that may be
incurred by the Owner Trustee therein or thereby. The right of the Owner Trustee
to perform any discretionary act enumerated in this Trust Agreement or in any
Basic Document shall not be construed as a duty, and the Owner Trustee shall not
be answerable for other than its gross negligence or willful misconduct in the
performance of any such act.

     (h) In no event shall the Owner Trustee be liable for any damages in the
nature of special, indirect or consequential damages, however styled, including,
without limitation, lost profits, or for any losses due to forces beyond the

constitute any default under its charter documents or bylaws or any indenture,
mortgage, contract, agreement or instrument to which it is a party or by which

                                       20

obligation of the Owner Trustee, enforceable against it in accordance with the

entering into this Trust Agreement or performing its obligations under this
Trust Agreement.

incur no liability to anyone in acting upon any signature, instrument, notice,
resolution, request, consent, order, certificate, report, opinion, note, or

signed by the proper party or parties. The Owner Trustee may accept a certified
copy of a resolution of the board of directors or other governing body of any
corporate party as conclusive evidence that such resolution has been duly
adopted by such body and that the same is in full force and effect. As to any

prescribed herein, the Owner Trustee may for all purposes hereof rely on a
certificate, signed by the president or any vice president or by the treasurer

the Owner Trustee under this Trust Agreement or any of the Basic Documents to
which the Owner Trustee is a party shall be made only from the income and

                         Termination of Trust Agreement

     Section 8.01. Termination of Trust Agreement. (a) This Trust Agreement
(other than Article VII and Section 10.08) shall terminate and the Trust shall
dissolve, wind up and terminate in accordance with Section 3808 of the Statutory
Trust Statute and be of no further force or effect upon the earlier of (i) the
final distribution of all moneys or other property or proceeds of the Owner
Trust Estate in accordance with the terms of the Indenture and this Trust
Agreement and (ii) the distribution of all of the assets of the Owner Trust
Estate, in accordance with written instructions provided to the Certificate
Paying Agent by the Majority Certificateholder, following the optional
redemption of the Notes effected by the Majority Certificateholder pursuant to
Section 8.06 of the Indenture; provided in each case that all amounts owing to
the Noteholders to the extent payable from the Owner Trust Estate or proceeds
thereof have been paid in full and that all obligations under the Indenture have
been discharged. The bankruptcy, liquidation, dissolution, death or incapacity
of any Certificateholder shall not (x) operate to terminate this Trust Agreement
or the Trust or (y) entitle such Certificateholder's legal representatives or
heirs to claim an accounting or to take any action or proceeding in any court
for a partition or winding up of all or any part of the Trust or the Owner Trust
Estate or (z) otherwise affect the rights, obligations and liabilities of the
parties hereto.

     (b) Except as provided in Section 8.01(a), the Depositor shall not be
entitled to revoke or terminate the Trust.

     (c) Notice of any termination of the Trust, specifying the Payment Date
upon which Certificateholders shall surrender their Certificates to the
Certificate Paying Agent for payment of the final distribution and cancellation,
shall be given by the Certificate Paying Agent by letter to Certificateholders
mailed within five Business Days of receipt of notice of the final payment on
the Notes from the Securities Administrator, stating (i) the Payment Date upon
or with respect to which final payment of the Certificates shall be made upon
presentation and surrender of the Certificates at the office of the Certificate
Paying Agent therein designated, (ii) the amount of any such final payment and
(iii) that the Record Date otherwise applicable to such Payment Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the office of the Certificate Payment Agent therein specified.
The Certificate Paying Agent shall give such notice to the Owner Trustee and the
Certificate Registrar at the time such notice is given to Certificateholders.
Upon presentation and surrender of the Certificates, the Certificate Paying
Agent shall cause to be distributed to Certificateholders amounts distributable
on such Payment Date pursuant to Section 5.01.

     In the event that all of the Certificateholders shall not surrender their
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Certificate Paying Agent shall give a second
written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. Subject to applicable laws with respect to escheat of funds, if within
one year following the Payment Date on which final payment of the Certificates
was to have been made pursuant to Section 3.03 of the Indenture, all the
Certificates shall not have been surrendered for

                                       26

<PAGE>

cancellation, the Certificate Paying Agent may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds and other assets that shall remain
subject to this Trust Agreement. Any funds remaining in the Certificate
Distribution Account after exhaustion of such remedies shall be distributed by
the Certificate Paying Agent to the Depositor.

     (d) Upon the winding up of the Trust and its termination, the Owner Trustee
shall, at the direction and expense of the Seller, cause the Certificate of
Trust to be cancelled by filing a certificate of cancellation with the Secretary
of State in accordance with the provisions of Section 3810(c) of the Statutory
Trust Statute.

                                   ARTICLE IX

             Successor Owner Trustees and Additional Owner Trustees

     Section 9.01. Eligibility Requirements for Owner Trustee. The Owner Trustee
shall at all times be a corporation satisfying the provisions of Section 3807(a)
of the Statutory Trust Statute; authorized to exercise corporate trust powers;
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state authorities; and having (or
having a parent that has) a rating of at least Baa3 by Moody's and/or at least
BBB- by Standard and Poor's or is otherwise acceptable to the Rating Agencies.
If such corporation shall publish reports of condition at least annually
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purpose of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Owner Trustee shall cease to be eligible in accordance with
the provisions of this Section 9.01, the Owner Trustee shall resign immediately
in the manner and with the effect specified in Section 9.02.

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

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

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

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

                                       28

<PAGE>

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

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

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

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

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

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

     (a) All rights, powers, duties and obligations conferred or imposed upon
the Owner Trustee shall be conferred upon and exercised or performed by the
Owner Trustee and such separate trustee or co-trustee jointly (it being
understood that such separate trustee or co-trustee

                                       29

<PAGE>

is not authorized to act separately without the Owner Trustee joining in such
act), except to the extent that under any law of any jurisdiction in which any
particular act or acts are to be performed, the Owner Trustee shall be
incompetent or unqualified to perform such act or acts, in which event such
rights, powers, duties and obligations (including the holding of title to the
Owner Trust Estate or any portion thereof in any such jurisdiction) shall be
exercised and performed singly by such separate trustee or co-trustee, but
solely at the direction of the Owner Trustee;

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

     (c) The Owner Trustee may at any time accept the resignation of or remove
any separate trustee or co-trustee.

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

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

                                  Miscellaneous

     Section 10.01. Amendments. (a) This Trust Agreement may be amended from
time to time by the parties hereto as specified in this Section, provided that
any amendment, except as provided in subparagraph (e) below, be accompanied by
an Opinion of Counsel addressed to the Owner Trustee, the Certificate Registrar
and the Certificate Paying Agent and obtained by the Depositor to the effect
that such amendment complies with the provisions of this Section. No amendment
to this Trust Agreement shall be made that would change the taxable status of
the Trust as either (A) a disregarded entity separate from its owner or (B) a
QRS, as provided for in Section 2.06 herein.

     (b) If the purpose of the amendment (as detailed therein) is to correct any
mistake, eliminate any inconsistency, cure any ambiguity or deal with any matter
not covered (i.e. to give effect to the intent of the parties and, if
applicable, to the expectations of the Holders), it shall not be necessary to
obtain the consent of any Noteholders or Certificateholders, but the Owner
Trustee, the Certificate Registrar and the Certificate Paying Agent shall be
furnished with an Opinion of Counsel obtained by the Depositor to the effect
that such action will not adversely affect in any material respect the interests
of any Noteholders or Certificateholders.

     (c) If the purpose of the amendment is to prevent the imposition of any
federal or state taxes at any time that any Security is outstanding, it shall
not be necessary to obtain the consent of any Noteholders or Certificateholders,
but the Owner Trustee, the Certificate Registrar and the Certificate Paying
Agent shall be furnished with an Opinion of Counsel obtained by the Depositor
that such amendment is necessary or helpful to prevent the imposition of such
taxes and is not materially adverse to any Noteholders or Certificateholders.

     (d) If the purpose of the amendment is to add or eliminate or change any
provision of the Trust Agreement other than as contemplated in (b) and (c)
above, the amendment shall require (A) an Opinion of Counsel obtained by the
Depositor to the effect that such action will not adversely affect in any
material respect the interests of any Noteholders or Certificateholders and (B)
the consent of Holders of Certificates evidencing a majority Percentage Interest
of the Certificates; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, payments received that are
required to be distributed on any Certificate without the consent of the related
Certificateholder or (ii) reduce the aforesaid percentage of Certificates the
Holders of which are required to consent to any such amendment, without the
consent of the Holders of all such Certificates then outstanding.
Notwithstanding the foregoing, the Issuer, at the direction of the Majority
Certificateholder, may amend Section 2.03 hereof. Any amendment of Section 2.03
hereof shall be accompanied by (i) an appropriate amendment to the applicable
Agreement, (ii) any Opinion of Counsel reasonably requested by the Underwriter,
the Rating Agencies, the Indenture Trustee and the Securities Administrator,
(iii) written confirmation from the Rating Agencies that such amendment will not
result in the rating of any Note to be downgraded, withdrawn or suspended, and
(iv) the consent of the Majority Certificateholder to the amendment of such
Section 2.03.

                                       31

<PAGE>

     (e) If the purpose of the amendment is to provide for the holding of any of
the Certificates in book-entry form, it shall require the consent of Holders of
all such Certificates then outstanding; provided, that the Opinion of Counsel
specified in subparagraph (a) above shall not be required.

     (f) If the purpose of the amendment is to provide for the issuance of
additional certificates representing an interest in the Trust, it shall not be
necessary to obtain the consent of any Holder, but the Owner Trustee shall be
furnished with (A) an Opinion of Counsel obtained by the Depositor to the effect
that such action will not adversely affect in any material respect the interests
of any Holders and (B) a letter from the Rating Agencies that the amendment will
not result in the downgrading or withdrawal of the rating then assigned to any
Notes or the rating then assigned to the Notes.

     (g) Promptly after the execution of any such amendment or consent, the
Depositor shall furnish written notification of the substance of such amendment
or consent to each Certificateholder, the Indenture Trustee and the Rating
Agencies. It shall not be necessary for the consent of Certificateholders,
Noteholders or the Indenture Trustee pursuant to this Section 10.01 to approve
the particular form of any proposed amendment or consent, but it shall be
sufficient if such consent shall approve the substance thereof. The manner of
obtaining such consents (and any other consents of Certificateholders provided
for in this Trust Agreement or in any other Basic Document) and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable requirements as the Owner Trustee may prescribe.

     (h) In connection with the execution of any amendment to any agreement to
which the Trust is a party, other than this Trust Agreement, the Owner Trustee,
the Certificate Registrar and the Certificate Paying Agent shall be entitled to
receive and conclusively rely upon an Opinion of Counsel to the effect that such
amendment is authorized or permitted by the documents subject to such amendment
and that all conditions precedent in the Basic Documents for the execution and
delivery thereof by the Trust or the Owner Trustee, as the case may be, have
been satisfied.

     (i) No amendment or agreement affecting the rights or duties of the Owner
Trustee, Certificate Registrar or the Certificate Paying Agent may be entered
into without the consent of the affected party. The Owner Trustee shall not be
required to enter into any amendment which adversely affects its rights, duties
or immunities under this Trust Agreement or the other Basic Documents.

     Promptly after the execution of any amendment to the Certificate of Trust,
the Owner Trustee shall cause the filing of such amendment with the Secretary of
State of the State of Delaware.

interest therein only in accordance with Articles V and VIII. No transfer, by
operation of law or otherwise, of any right, title or interest of the
Certificateholders

statutory trust formed by MERRILL LYNCH MORTGAGE INVESTORS, INC., as depositor,
pursuant to the Trust Agreement referred to below.

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

     The Trust was created pursuant to a Trust Agreement, dated as of December
22, 2005, among the Depositor, Wilmington Trust Company, as owner trustee (the
"Owner Trustee", which term includes any successor entity under the Trust
Agreement) and Wells Fargo Bank, N.A. in its capacity as Securities
Administrator as Certificate Registrar and Certificate Paying Agent (the "Trust
Agreement"), a summary of certain of the pertinent provisions of which is set

provisions and conditions of the Trust Agreement, to which Trust Agreement the
Holder of this Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

     This Certificate is one of a duly authorized issue of Trust Certificates,
Series 2005-A9 (herein called the "Certificates") issued under the Trust
Agreement to which reference is hereby made for a statement of the respective
rights thereunder of the Depositor, the Owner Trustee and the Holders of the
Certificates and the terms upon which the Certificates are executed and
delivered. All terms used in this Certificate which are defined in the Trust

immediately preceding such Payment Date (the "Record Date"), such
Certificateholder's Percentage Interest in the amount to be distributed to
Certificateholders on such Payment Date.

                                       A-3

<PAGE>

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

     The Holder of this Certificate acknowledges and agrees that its rights to
receive distributions in respect of this Certificate are subordinated to the
rights of the Noteholders as described in the Indenture, dated as of December
22, 2005, among the Trust, Wachovia Bank, National Association, as Indenture
Trustee and Wells Fargo Bank, N.A., as Securities Administrator (the
"Indenture").

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

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

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

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

     The Mortgage Loans are subject to purchase in whole, but not in part, by
the Majority Certificateholder, on any Payment Date on or after the Payment Date
on which the aggregate Stated Principal Balance of the Mortgage Loans as of the
end of the prior Due Period is less than or equal to 10% of the Stated Principal
Balance of the Mortgage Loans as of the Cut-off Date.

     No transfer, sale, pledge or other disposition of a Certificate shall be
made unless such transfer, sale, pledge or other disposition is exempt from the
registration requirements of the Securities Act and any applicable state
securities laws or is made in accordance with said Act and laws. In the event of
any such transfer, the Certificate Registrar or the Depositor shall prior to
such transfer require the transferee to execute (A) either (i) (a) an investment
letter in

<PAGE>

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

     No transfer of Certificates or any interest therein shall be made to an
employee benefit plan or arrangement subject to Title I of ERISA, a plan subject
to Section 4975 of the Code, or a plan subject to any provisions under any
federal, state, local, non-U.S. or other laws or regulations that are
substantively similar to the foregoing provisions of ERISA or the Code
(collectively, a "Plan"), or any Person directly or indirectly acquiring the
Certificates for, on behalf of or with any assets of any such Plan.

     No transfer, sale, pledge or other disposition of a Certificate or any
interest therein shall be made, and the Certificate Registrar shall refuse to
register any such transfer, sale, pledge or other disposition, unless (A) the
transferee shall have delivered to the Certificate Registrar, the Owner Trustee,
the Securities Administrator and the Indenture Trustee a certificate certifying
that (i) it is a real estate investment trust ("REIT") within the meaning of
Section 856(a) of the Code or a qualified REIT subsidiary ("QRS") within the
meaning of Section 856(i) of the Code or an entity disregarded as an entity
separate from a REIT or a QRS and (ii) following the transfer, 100% of the
Certificates, the Class 4-A-2 Notes and the Subordinate Notes (other than any of

Administrator) will be owned by a single REIT, directly or indirectly through
one or more qualified QRSs of such REIT or one or more entities disregarded as
entities separate from such REIT or such QRSs and (B) the proposed transferor
delivers to the Owner Trustee, the Certificate Registrar, the Securities
Administrator and the Indenture Trustee an Opinion of Counsel, rendered by a law
firm generally recognized to be qualified to opine concerning the tax aspects of
asset securitization, to the effect that, following such transfer, the Trust
will continue to be treated for federal income tax purposes as either a
disregarded entity or a QRS; provided that, notwithstanding the foregoing, (x)
any Certificates may be pledged to secure indebtedness and may be the subject of
repurchase agreements treated by the Issuer as secured indebtedness for federal
income tax purposes, and (y) any Certificates may be transferred by the related
lender under any such related loan agreement or repurchase agreement upon a
default under any such indebtedness, in which case the transferor shall deliver
to the Certificate Registrar, the Securities Administrator, the Owner Trustee
and the Indenture Trustee a certificate certifying to such effect.

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

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

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

                            [REVERSE OF CERTIFICATE]

     The Certificates do not represent an obligation of, or an interest in, the
Depositor, the Seller, the Master Servicer, the Servicer, the Securities
Administrator, the Indenture Trustee, the Certificate Paying Agent, the
Certificate Registrar, the Owner Trustee or any Affiliates of any of them and no
recourse may be had against such parties or their assets, except as expressly
set forth or contemplated herein or in the Trust Agreement or the Basic
Documents. In addition, this Certificate is not guaranteed by any governmental
agency or instrumentality and is limited in right of payment to certain
collections and recoveries with respect to the Mortgage Loans, all as more
specifically set forth herein and in the Trust Agreement. A copy of the Trust
Agreement may be examined by any Certificateholder upon written request during
normal business hours at the principal office of the Depositor and at such other
places, if any, designated by the Depositor.

     The Trust Agreement permits the amendment thereof as specified below,
provided that any amendment be accompanied by an Opinion of Counsel to the Owner
Trustee to the effect that such amendment complies with the provisions of the
Trust Agreement and would not cause the Trust to be subject to an entity level
tax. If the purpose of the amendment is to correct any mistake, eliminate any
inconsistency, cure any ambiguity or deal with any matter not covered, it shall
not be necessary to obtain the consent of any Holder, but the Owner Trustee
shall be furnished with a letter from each of the Rating Agencies that the
amendment will not result in the downgrading or withdrawal of the rating then
assigned to any Note or the rating then assigned to any Note. If the purpose of
the amendment is to prevent the imposition of any federal or state taxes at any
time that any Security is outstanding, it shall not be necessary to obtain the
consent of any Holder, but the Owner Trustee shall be furnished with an Opinion
of Counsel that such amendment is necessary or helpful to prevent the imposition
of such taxes and is not materially adverse to any Holder. If the purpose of the
amendment is to add or eliminate or change any provision of the Trust Agreement,
other than as specified in the preceding two sentences, the amendment shall
require either (a) a letter from each of the Rating Agencies that the amendment
will not result in the downgrading or withdrawal of the rating then assigned to
any Note or the rating then assigned to any Note or (b) the consent of Holders
of the Certificates evidencing a majority of the Percentage Interests of the
Certificates and the Indenture Trustee; provided, however, that no such
amendment shall (i) reduce in any manner the amount of, or delay the time of,
payments received that are required to be distributed on any Certificate without
the consent of the related Certificateholder, or (ii) reduce the aforesaid
percentage of Certificates the Holders of which are required to consent to any
such amendment without the consent of the Holders of all such Certificates then
outstanding.

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

                                       A-8

<PAGE>

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

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

     The obligations and responsibilities created by the Trust Agreement and the
Trust created thereby shall terminate as and when provided in accordance with
the terms of the Trust Agreement.

made of any changes in the information and conclusions herein. Until such notice

offers to buy any Certificates from, any person, or otherwise approached or
negotiated with any person with respect thereto, or taken any other action which
would result in a violation of Section 5 of the Act, and (g) we will not sell,
transfer or otherwise dispose of any Certificates unless (1) such sale, transfer
or other disposition is made pursuant to an effective registration statement
under the Act or is exempt from such registration requirements, and if
requested, we will at our expense provide an Opinion of Counsel satisfactory to
the addressees of this certificate that such sale, transfer or other disposition
may be made pursuant to an exemption from the Act, (2) the purchaser or
