         (c)      If on any Payment Date on which the aggregate Note Principal
                  Balance of Senior Notes in a Note Group would be greater than
                  the aggregate Scheduled Principal Balance of the Mortgage
                  Loans in the related Loan Group and any Subordinate Notes are
                  still outstanding, in each case after giving effect to

                  amounts otherwise allocable to the Subordinate Notes in
                  respect of principal will be distributed to such Class or
                  Classes of Senior Notes in reduction of the Note Principal
                  Balances thereof, until the aggregate Note Principal Balance
                  of such Class or Classes of Senior Notes is an amount equal to
                  the aggregate Scheduled Principal Balance of the Mortgage
                  Loans in the related Loan Group, and (B) the Accrued Note
                  Interest otherwise allocable to the Subordinate Notes on such
                  Payment Date will be reduced, if necessary, and distributed to
                  such Class or Classes of Senior Notes in an amount equal to
                  the Accrued Note Interest for such Payment Date on the excess
                  of (x) the aggregate Note Principal Balance of such Class or
                  Classes of Senior Notes over (y) the aggregate Scheduled
                  Principal Balance of the Mortgage Loans in the related Loan
                  Group. Any such reduction in the Accrued Note Interest on the
                  Subordinate Certificates will be allocated in reverse order of
                  the Subordinate Certificates numerical designations,
                  commencing with the Class X-1 Notes.

         (d) If, after distributions have been made pursuant to priorities FIRST
and SECOND of clauses (a)(I) and (II) above on any Payment Date, the remaining
Group I Available Funds and Group II Available Funds are less than the Group I
Senior Optimal Principal Amount and Group II Senior Optimal Principal Amount,
respectively, the Senior Optimal Principal Amount for such Loan Group shall be
reduced, and such remaining Available Funds for a Loan Group will be distributed
on the related Senior Notes, on a pro rata basis, on the basis of such reduced
amount.

         (e) No Accrued Note Interest will be payable with respect to any Class
of Notes after the Payment Date on which the Note Principal Balance or Notional
Amount of such Note has been reduced to zero.

         (f) If on any Payment Date the Interest Funds for the Senior Notes in
any Note Group is less than the Accrued Note Interest on the related Senior
Notes 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.

         (g) 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 crediting the amount 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.

         (h) 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.

         (i) 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

                                        9

such Payment Date pursuant to such Holder's Notes; PROVIDED, HOWEVER, that the

         Section 3.18 DETERMINATION OF NOTE INDEX.

         On each Interest Determination Date, the Securities Administrator will

Period for the Class A-1 Notes and the Class A-3 Notes and the One-Year LIBOR
Note Index for the next Interest Accrual Period for the Class A-2 Notes and the
Class A-4 Notes.

         On each Interest Determination Date for the Class A-1 Notes and the
Class A-3 Notes, the One-Year U.S. Treasury Note Index will be based on the
weekly average yield on U.S. Treasury securities adjusted to a constant maturity
of one year as reported in the Release on the related Interest Determination
Date or, if not so available, as most recently available immediately prior to
such Interest Determination Date.

         On each Interest Determination Date for the Class A-2 Notes and the
Class A-4 Notes, the One-Year U.S. LIBOR Note Index will be based on the London
interbank offered rate for one-year United States dollar deposits as such rate
appears on the Telerate Screen Page 3750, as of 11:00 a.m. (London time) on such
Interest Determination Date. If the rate for the One-Year LIBOR Note Index does
not appear or is not available on Telerate Screen Page 3750, the One-Year LIBOR
Note Index for the related Interest Accrual Period for the Class A-2 Notes and
the Class A-4 Notes will be established by the Securities Administrator as
follows:

         (a) If on such Interest Determination Date two or more Reference Banks
provide such offered quotations, the One-Year LIBOR Note Index for the related
Interest Accrual Period shall be the arithmetic mean of such offered quotations
(rounded upwards if necessary to the nearest whole multiple of 0.0625%).

         (b) If on such Interest Determination Date fewer than two Reference
Banks provide such offered quotations, the One-Year LIBOR Note Index for the
related Interest Accrual Period shall be the higher of (x) the One-Year LIBOR
Note Index as determined on the previous Interest Determination Date and (y) the
Reserve Interest Rate.

         The establishment of the One-Year U.S. Treasury Note Index and the
One-Year LIBOR Note Index on each Interest Determination Date by the Securities
Administrator and the Securities Administrator's calculation of the rate of
interest applicable to the related Class of Notes for the related Interest
Accrual Period shall (in the absence of manifest error) be final and binding.

         Section 3.19 RESTRICTED PAYMENTS. The Issuer shall not, directly or
indirectly, (i) pay any dividend or make any distribution (by reduction of
capital or otherwise), whether in cash, property, securities or a combination
thereof, to the Owner Trustee or any owner of a beneficial interest in the
Issuer or otherwise with respect to any ownership or equity interest or security
in or of the Issuer, (ii) redeem, purchase, retire or otherwise acquire for
value any such ownership or equity interest or security or (iii) set aside or
otherwise segregate any amounts for any such purpose; PROVIDED, HOWEVER, that
the Issuer may make, or cause to be made, (x) distributions and payments to the
Owner Trustee,

from the Master Servicer Collection Account or the Payment Account except in
accordance with this Indenture and the Basic Documents.

         Section 3.21 FURTHER INSTRUMENTS AND ACTS. Upon request of the
Indenture Trustee, the Issuer will execute and deliver such further instruments
and do such further acts as may be reasonably necessary or proper to carry out

activities permitted by the Issuer hereunder.

         Section 3.23 CERTAIN REPRESENTATIONS REGARDING THE TRUST ESTATE.

                  (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 related Servicer 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 (other than the Class X-1 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-6 Notes until the Note Principal Balance thereof
has been reduced to zero;

         SECOND, to the Class B-5 Notes until the Note Principal Balance thereof
has been reduced to zero;

         THIRD, to the Class B-4 Notes until the Note Principal Balance thereof
has been reduced to zero;

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

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

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

         SEVENTH, with respect to the principal portion of Realized Losses on
the Group I Loans, first, to the Class A-3 Notes until the Note Principal
Balance thereof has been reduced to zero and second, to the Class A-1 Notes
until the Note Principal Balance thereof has been reduced to zero; and with
respect to the principal portion of Realized Losses on the Group II Loans,
first, to the Class A-4 Notes until the Note Principal Balance thereof has been
reduced to zero and second, to the Class A-2 Notes until the Note Principal
Balance thereof has been reduced to zero.

         (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 (other than the Class
X-1 Notes) 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.

                                       18

<PAGE>

         (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) On each Payment Date, the Securities Administrator shall determine
the Subordinate Writedown Amount. Any such Subordinate Writedown Amount shall
effect a corresponding reduction in the Note Principal Balance of (i) with
respect to the Subordinate Writedown Amount, if prior to the Cross-Over Date,
the Class B-6, Class B-5, Class B-4, Class B-3, Class B-2 and Class B-1 Notes,
in that order, and (iii) from and after the Cross-Over Date, to the Senior
Notes, in accordance with priorities set forth in clause (b) above, in each
case, on such Payment Date after giving effect to distributions made on such
Payment Date.

         (g) The interest portion of any Realized Losses with respect to the
Mortgage Loans occurring on or prior to the Cross-Over Date will be borne
sequentially to the Class B-6, Class B-5, Class B-4, Class X-1, Class B-3, Class
B-2 and Class B-1, in that order. Once the aggregate Note Principal Balance or
Notional Amount, as applicable, of the Subordinate Notes have been reduced to
zero, the interest portion of Realized Losses on the Group I Loans will be
allocated first to the Class A-3 Notes, and then to the Class A-1 Notes, and the
interest portion of Realized Losses on the Group II Loans will be allocated
first to the Class A-4 Notes, and then to the Class A-2 Notes, in each case in
reduction Accrued Note Interest on such Class.

         (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.

         Section 3.25 PERMITTED WITHDRAWALS AND TRANSFERS FROM THE PAYMENT
ACCOUNT. (a) The Securities Administrator will, from time to time on demand of
the Master Servicer, make or cause to be made such withdrawals or transfers from
the Payment Account as the Master Servicer has designated for such transfer or
withdrawal pursuant to the Servicing Agreement or as the Securities
Administrator has instructed hereunder for the following purposes (limited in
the case of amounts due

Insurance Proceeds relating to a particular Mortgage Loan for insured expenses
incurred with respect to such Mortgage Loan and to reimburse the Master Servicer
or the Servicer from Liquidation Proceeds from a particular Mortgage Loan for

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;

been reimbursed pursuant to clauses (i) and (iv);

                  (vi) to pay the Master Servicer as set forth in Section 2.13
of the Servicing Agreement; provided however, that the Master Servicer shall be

compensation, any Excess Liquidation Proceeds to the extent not retained by the
Servicer;

                                   ARTICLE IV

               The Notes; Satisfaction and Discharge of Indenture

         Section 4.01 THE NOTES. Each Class of Class A-1 Notes and Class A-2
Notes shall be registered in the name of a nominee designated by the Depository.
Beneficial Owners will hold interests in the Class A-1 Notes and Class A-2 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.
Registered Holders will hold interests in the Class X-1 Notes in physical form
in minimum initial Notional Amount of $25,000 and integral multiples of $1 in
excess thereof. Registered Holders will hold interests in the Class A-3, Class
A-4, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Notes
in physical form in minimum initial Note Principal Balances of $25,000 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 Owner Trustee, not in its individual capacity but solely as Owner
Trustee, authenticated by the Securities Administrator and delivered by the
Securities Administrator to or upon the order of the Issuer.

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

                                       22

<PAGE>

         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 Class A-3 Notes,
Class A-4 Notes or Subordinate Notes (other than any Class A-3 Notes, Class A-4
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) or interest therein shall be made, and the Note
Registrar shall refuse to register any such transfer, sale, pledge or other
disposition, so long as the Class A-1 Notes and Class A-2 Notes, and any Class
A-3 Notes, Class A-4 Notes or Subordinate Notes with

                                       23

<PAGE>

respect to which a "will be debt" opinion has been rendered by nationally
recognized tax counsel are outstanding, 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") or a
qualified REIT subsidiary ("QRS") within the meaning of Section 856(a) or
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 and
Class A-3 Notes, Class A-4 Notes and Subordinate Notes (other than any Class A-3
Notes, Class A-4 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 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; provided
that (x) any Class A-3 Notes, Class A-4 Notes or Subordinate Notes 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) any
Class A-3 Notes, Class A-4 Notes or Subordinate 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, the Securities Administrator, the Owner Trustee
and the Indenture Trustee 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

                                       24

<PAGE>

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 Issuer shall execute, and upon its
request the Securities Administrator shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a
replacement Note; PROVIDED, HOWEVER, that if any such destroyed, lost or stolen
Note, but not a mutilated Note, shall have become or within seven days shall be
due and payable, instead of issuing a replacement Note, the Issuer may pay such
destroyed, lost or stolen Note when so due or payable without surrender thereof.
If, after the delivery of such replacement Note or payment of a destroyed, lost
or stolen Note pursuant to the proviso to the preceding sentence, a bona fide
purchaser of the original Note in lieu of which such replacement Note was issued
presents for payment such original Note, the Issuer and the Securities
Administrator shall be entitled to recover such replacement Note (or such
payment) from the Person to whom it was delivered or any Person taking such
replacement Note from such Person to whom such replacement Note was delivered or
any assignee of such Person, except a bona fide purchaser, and shall be entitled
to recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expense incurred by the Issuer, the Indenture Trustee or
the Securities Administrator in connection therewith.

         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

                                       25

<PAGE>

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

         Section 4.06 BOOK-ENTRY NOTES. The Class A-1 Notes and Class A-2 Notes,
upon original issuance, will be issued in the form of typewritten Notes
representing the Book-Entry Notes, to be delivered to The Depository Trust
Company, the initial Depository, by, or on behalf of, the Issuer. The Notes
shall initially be registered on the Note Register in the name of Cede & Co.,
the nominee of the initial Depository, and no Beneficial Owner will receive a
Definitive Note representing such Beneficial Owner's interest in such Note,
except as provided in Section 4.08. With respect to such Notes, unless and until
definitive, fully registered Notes (the "Definitive Notes") have been issued to
Beneficial Owners pursuant to Section 4.08:

                           (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.

         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 A-3, Class A-4, Class X-1, Class B-1, Class B-2, Class B-3,
Class B-4, Class B-5 and Class B-6 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

                                       27

<PAGE>

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
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 A-1 Notes and Class A-2 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. The Issuer and the
Securities Administrator (in accordance with Section 6.07 hereof), by entering
into this Indenture, and each Class A-1 Noteholder and Class A-2 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.

         Section 4.10 SATISFACTION AND DISCHARGE OF INDENTURE. (a) This
Indenture shall cease to be of further effect with respect to the Notes except
as to (i) rights of registration of transfer and exchange, (ii) substitution of
mutilated, destroyed, lost or stolen Notes, (iii) rights of Noteholders to
receive payments of principal thereof and interest thereon, (iv) Sections 3.03,
3.04, 3.06, 3.09, 3.17, 3.19 and 3.20, (v) the rights, obligations 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,

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

                           c.       have been called for early redemption and
                                    the Trust has been terminated pursuant to
                                    Section 8.06 hereof,

                                       28

<PAGE>

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.

         (b) Notwithstanding the foregoing, so long as the Investor owns 100% of
the Securities, the Investor shall not be permitted to discharge the Indenture
as set forth in this Section 4.10.

         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

                                       29

<PAGE>

which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Notes may
determine, as evidenced by their execution of such Notes.

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

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

         No transfer of any Class A-3, Class A-4, Class X-1, Class B-1, Class
B-2, Class B-3, Class B-4, Class B-5 or Class B-6 Notes or any interest therein
shall be made to any Person unless the Indenture Trustee and the Note Registrar
are provided with an Opinion of Counsel which establishes to the satisfaction of
the Indenture Trustee and the Note Registrar that the purchase of the Notes is
permissible under applicable law, will not constitute or result in any
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Issuer, the Seller, the Owner Trustee, the Indenture Trustee, the
Master Servicer or the Note Registrar to any obligation or liability (including
obligations or liabilities under ERISA or Section 4975 of the Code) in addition
to those undertaken in this Agreement, which Opinion of Counsel shall not be an
expense of the Depositor, the Owner Trustee, the Indenture Trustee, the
Securities Administrator, the Notes Registrar or the Master Servicer. In lieu of
such Opinion of Counsel, a Person acquiring the Notes may provide a
certification in the form each attached hereto as paragraph 3 of Exhibit C or
clause (d) of Exhibit D, which the Issuer, the Seller, the Owner Trustee, the
Indenture Trustee, the Master Servicer and the Note Registrar may rely upon
without further inquiry or investigation. Neither an Opinion of Counsel nor

                                       30

<PAGE>

a certification will be required in connection with the initial transfer of any
such Notes by the Depositor to an affiliate of the Depositor (in which case, the
Depositor or any affiliate thereof shall be deemed to have represented that such
affiliate is not a Plan or a Person investing Plan Assets of any Plan) and the
Owner Trustee, the Indenture Trustee, the Master Servicer and the Note Register
shall be entitled to conclusively rely upon a representation (which, upon the
request of the Owner Trustee, the Indenture Trustee, the Master Servicer and the
Note Register, shall be a written representation) from the Depositor of the
status of such transferee as an affiliate of the Depositor.

                                    ARTICLE V

                              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 Notes representing
not less than a majority of the aggregate Note Principal Balance of the Notes
may declare the Notes to be immediately due and payable, by a notice in writing
to the Issuer (and to the Indenture Trustee if such notice is given by
Noteholders), and upon any such declaration the unpaid Note Principal Balance of
the Notes, together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable.

         At any time after such declaration of acceleration of maturity with
respect to an Event of Default has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as
hereinafter in this Article V provided, Holders of the Notes representing not
less than a majority of the aggregate Note Principal Balance of 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
         Notes and all other amounts that would then be due hereunder or under
         the Notes if the Event of Default giving rise to such acceleration had
         not occurred;

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

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

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

<PAGE>

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

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

         (b) In case the Issuer shall fail forthwith to pay such amounts upon
such demand, the Indenture Trustee, in its own name and as trustee of an express
trust, subject to the provisions of Section 10.15 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 Balances of each Class of Notes, to protect and enforce
any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy or legal or equitable right vested
in the Indenture Trustee by this Indenture or by law.

         (d) In case there shall be pending, relative to the Issuer or any other
obligor upon the Notes or any Person having or claiming an ownership interest in
the Trust Estate, Proceedings under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, as directed in writing by Holders
of a majority of the aggregate Note Principal Balances of 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
         Notes and to file such other papers or

                                       33

<PAGE>

         documents as may be necessary or advisable in order to have the claims
         of the Indenture Trustee (including any claim for reasonable
         compensation to the Indenture Trustee and each predecessor Indenture
         Trustee, and their respective agents, attorneys and counsel, and for
         reimbursement of all expenses and liabilities incurred, and all
         advances made, by the Indenture Trustee and each predecessor Indenture
         Trustee, except as a result of negligence, 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.

         (g) In any Proceedings brought by the Indenture Trustee (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall

                                       34

<PAGE>

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

the Holders of a majority of the aggregate Note Principal Balances of the Notes,

                           (iv) exercise its rights as Holder of the Class A
         Grantor Trust Certificate pursuant to Section 7.02 of the Grantor Trust
         Agreement (provided, that the Indenture Trustee shall not exercise its
         rights under such Section 7.02 unless and until an Event of Default has
         occurred and is continuing); and

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

PROVIDED, HOWEVER, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate following an Event of Default, unless (A) the
Indenture Trustee obtains the consent of the Holders of 100% of the aggregate
Note Principal Balance of the Notes then outstanding, (B) the proceeds of such
sale or liquidation distributable to the Holders of the Notes are sufficient to
discharge in full all amounts then due and unpaid upon such Notes for principal
and interest or (C) the Indenture Trustee determines that the Mortgage Loans
will not continue to provide sufficient funds for the payment of principal of
and interest on the applicable Notes as they would have become due if the Notes
had not been declared due and payable, and the Indenture Trustee obtains the
consent of the Holders of 66 2/3% of the aggregate Note Principal Balance of
each Class of Notes then outstanding, voting separately; provided that, so long
as the Investor owns 100% of the Securities, the Investor shall not be permitted
to consent to such sale or liquidation of the Trust Estate. 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

                                       35

<PAGE>

than any Servicer as to which an Event of Servicer Termination has occurred and
is continuing) as provided in the Wells Fargo Servicing Agreement.

shall pay out the money or property in the following order:

                  FIRST: to the Indenture Trustee, the Securities Administrator,

         Class is reduced to zero;

                  FOURTH: to the Class A-1 Noteholders and Class A-2
         Noteholders, pro rata, in each case based on the amount of any Basis
         Risk Shortfall Carryover Amounts not previously paid;

                  FIFTH: to the Class A-3 Noteholders and Class A-4 Noteholders,

         Noteholders, pro rata, in each case based on the amount of any Basis

         Class B-2 Noteholders, and third, to the Class B-3 Noteholders,
         according to the amounts due and payable on such Classes of Notes for

         Class B-5 Noteholders and third, to the Class B-6 Noteholders,

         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. So long as the Investor owns 100% of
the Securities, 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. 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 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;

                           (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

                                       37

<PAGE>

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

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

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

<PAGE>

         Section 5.11 CONTROL BY NOTEHOLDERS. The Holders of a majority of the
aggregate Note Principal Balances of Notes shall have the right to direct the
time, method and place of conducting any Proceeding for any remedy available to
the Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on the Indenture Trustee; 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 Notes
         or the Holders of 66 2/3% of the aggregate Note Principal Balance of
         each Class of 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 Notes representing a majority of the
         Note Principal Balances of the Notes.

Notwithstanding the rights of Noteholders set forth in this Section 5.11 the
Indenture Trustee need not take any action that it 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 Notes may waive any past Event of Default and
its consequences except an Event of Default (a) with respect to payment of
principal of or interest on any of the Notes, or (b) in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Note. In the case of any such waiver, the Issuer, the Indenture
Trustee and the Holders of the Notes shall be restored to their former positions
and rights hereunder, respectively, but no such waiver shall extend to any
subsequent or other Event of Default or impair any right consequent thereto.

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

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

                                       39

<PAGE>

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 Notes consent to or direct the
         Indenture Trustee to make, such Sale, or

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

                  (3) the Indenture Trustee determines that the conditions for
         retention of the Trust Estate set forth in Section 5.05 hereof cannot
         be satisfied (in making any such determination, 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 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 Notes or the Holders
of 66 2/3% of the aggregate Note Principal Balance of each Class of Notes then
outstanding, voting separately as set forth in Section 5.04(a) hereof, have
otherwise consented or directed the Indenture Trustee, at any public Sale of all
or any portion of the Trust Estate at which a minimum bid equal to or greater
than the amount

                                       40

<PAGE>

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.

         (e) So long as the Investor owns 100% of the Securities, the Investor
shall not consent to any Sale of the Trust Estate as set forth herein.

         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

                                       41

<PAGE>

any other relief under or with respect to this Indenture. Neither the lien of
this Indenture nor any rights or remedies of the Indenture Trustee or the
Noteholders shall be impaired by the recovery of any judgment by the Indenture
Trustee against the Issuer or by the levy of any execution under such judgment
upon any portion of the Trust Estate or upon any of the assets of the Issuer.
Any money or property collected by the Indenture Trustee or the Securities
Administrator shall be applied by the Securities Administrator in accordance
with Section 5.04(b) hereof.

             The Indenture Trustee and The Securities Administrator

         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

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

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) The Indenture Trustee and the Securities Administrator may rely on any

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

                                       44

<PAGE>

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,

                                       45

<PAGE>

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

         (l) Neither the Indenture Trustee nor the Securities Administrator
shall be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of Notes representing not less than 25%
of the Note Principal Balance of the Notes and provided that the payment within
a reasonable time to the Indenture Trustee or the Securities Administrator, as
applicable, of the costs, expenses or liabilities likely to be incurred by it in
the making of such investigation is, in the opinion of the Indenture Trustee or
the Securities Administrator, as applicable, reasonably assured to the Indenture
Trustee 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

                                       46

<PAGE>

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

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

         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 Agreement or any claim or legal action (including any
pending or threatened claim or legal action) or otherwise incurred or made by
the Indenture Trustee or the Securities Administrator, respectively, in the
administration of the trusts hereunder (including the reasonable compensation,
expenses and disbursements of its counsel) except any such expense, disbursement
or advance as may arise from its own negligence or intentional misconduct or
which is the responsibility of the Noteholders as provided herein. Such

                                       47

<PAGE>

compensation and reimbursement obligation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust.
Additionally, each of the Indenture Trustee and the Securities Administrator and
any director, officer, employee or agent of the Indenture Trustee or the
Securities Administrator shall be indemnified by the Trust and held harmless
against any loss, liability or expense (including reasonable attorney's fees and
expenses) incurred in the administration of this Agreement (other than its
ordinary out of pocket expenses incurred hereunder) or in connection with any
claim or legal action relating to (a) the Basic Documents or (b) the Notes,
other than any loss, liability or expense incurred by reason of its own
negligence or intentional misconduct, or which is the responsibility of the
Noteholders as provided herein.

         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.

                                       48

<PAGE>

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

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

                                       49

<PAGE>

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 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

                                       50

<PAGE>

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.

         Section 6.12 ELIGIBILITY; DISQUALIFICATION. The Indenture Trustee shall
at all times be an entity that meets the requirements of Section 3(c)(3) under
the Investment Company Act of 1940 applicable to a trustee, and shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition and it or its parent shall have a
long-term debt rating of Baa3 or better by Moody's.

hereby represents that:

same information in an alternative format) available each month to Noteholders,
each Noteholder and each Certificateholder, the Depositor, the Issuer, the
Seller, the Owner Trustee, the Certificate Paying Agent and the Rating Agency
via the Securities Administrator's website. The Securities Administrator's
website shall initially be located at "www.ctslink.com." Assistance in using the

service desk at (301) 815-6600. Parties that are unable to use the website are
entitled to have a paper copy mailed to them via first class mail by calling the
Securities Administrator's customer service desk and indicating such. The
Securities Administrator may have the right to change the way the monthly
statements are distributed in order to make such distribution more convenient
and/or more accessible to the above parties and the Securities Administrator
shall provide timely and adequate notification to all above parties regarding
any such changes.

         The Securities Administrator shall be entitled to rely on but shall not
be responsible for the content or accuracy of any information provided by third

         Section 7.05 REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION.
Within 15 days after each Payment Date, the Securities Administrator shall, in

Form containing the same or comparable information or other information mutually
agreed upon) with a copy of the statement to the Noteholders for such Payment
Date as an exhibit thereto. Prior to January 30 in any year, the Securities
Administrator shall, in accordance with industry standards and only if
instructed by the Depositor, file a Form 15 Suspension Notice with respect to
the Trust Estate, if applicable. Prior to (i) March 31, 2006, or such earlier
filing date as may be required by the Commission, and (ii) unless and until a
Form 15 Suspension Notice shall have been filed, March 31 of each year
thereafter, or such earlier filing date as may be required by the Commission,
the Securities Administrator shall file a Form 10-K, in substance conforming to

to execute and file each such document on behalf of the Depositor. Such power of
attorney shall continue until either the earlier of (i) receipt by the
Securities Administrator from the Depositor of written termination of such power
of attorney and (ii) the termination of the Trust Estate. The Depositor agrees
to promptly furnish to the Securities Administrator, from time to time upon
request, such further information, reports and financial statements within its
control related to this Agreement and the Mortgage Loans as the Securities
Administrator reasonably deems appropriate to prepare and file all necessary
reports with the Commission. The Securities Administrator shall have no
responsibility to file any items other than those specified in this Section
7.05; provided, however, the Securities Administrator will cooperate with the
Depositor and the Issuer in connection with any additional filings with respect
to the Trust Estate as the Depositor deems necessary under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). Fees and expenses
incurred by the Securities Administrator in connection with this Section 7.05
shall not be reimbursable from the Trust Estate.

provided 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 Securities Administrator that there are no Notes Outstanding and (ii) all
sums then due and unpaid to the

                                       57

<PAGE>

Indenture Trustee pursuant to this Indenture have been paid, release any
remaining portion of the Trust Estate that secured the Notes from the lien of
this Indenture.

         (c) The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.05 only upon receipt of a request from the
Issuer.

         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 less than or
equal to 10% of the aggregate Scheduled Principal Balance of the Mortgage Loans
as of Cut-off 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 Interest Rate through such
Payment Date (including any related Net Interest Shortfall, 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 Interest Rate.

         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 indenture; or

                           (vii) to evidence and provide for the acceptance of

rendered by nationally recognized tax counsel and furnished to the Securities
Administrator.

         The Indenture Trustee and the Securities Administrator are hereby

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

         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.

                                       62

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 and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture
for any and all purposes.

         Section 9.05 CONFORMITY WITH TRUST INDENTURE ACT. Every amendment of
this Indenture and every supplemental indenture executed pursuant to this
Article IX shall conform to the requirements of the Trust Indenture Act as then
in effect 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 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

                                       64

<PAGE>

         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.

                                       65

<PAGE>

         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

                                       66

<PAGE>

         with the Securities Administrator at Wells Fargo Bank, National
         Association, P.O. Box 98, Columbia Maryland 21046 (or, in the case of
         overnight deliveries, 9062 Old Annapolis Road, Columbia, Maryland
         21045), Attn: BART 2005-2, 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: Bear Stearns ARM Trust 2005-2, in
         care of Wilmington Trust Company, Rodney Square North, 1100 North
         Market Street, Wilmington, Delaware 19990-0001, Attention: Corporate
         Trust Administration, or at any other address previously furnished in
         writing to the Indenture Trustee by the Issuer. The Issuer shall
         promptly transmit any notice received by it from the Noteholders to the
         Indenture Trustee.

         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 Moody's, to
Moody's, at the following address: Moody's Investors Service, Inc., 99 Church
Street, New York, New York 10007; 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.

                                       67

<PAGE>

         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.

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

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

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

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

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

         Section 10.10 LEGAL HOLIDAYS. In any case where the date on which any
payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Notes or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

         Section 10.11 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW
YORK GENERAL OBLIGATIONS LAWS, WHICH SHALL APPLY HERETO), AND THE OBLIGATIONS,
RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

         Section 10.12 COUNTERPARTS. This Indenture may be executed in any
number of counterparts, each of which when so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

         Section 10.13 RECORDING OF INDENTURE. If this Indenture is subject to
recording in any appropriate public recording offices, such recording is to be
effected by the Issuer and at its expense accompanied by an Opinion of Counsel
at its expense (which may be counsel to the Indenture Trustee or any other
counsel reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection of the Noteholders or any other
Person secured hereunder or for the enforcement of any right or remedy granted
to the Indenture Trustee under this Indenture.

         Section 10.14 ISSUER OBLIGATION. No recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the Owner Trustee or
the Securities Administrator on the Notes or under this Indenture or any
certificate or other writing delivered in connection herewith or therewith,
against (i) the Indenture Trustee or the Owner Trustee in its individual
capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any
partner, owner, beneficiary, agent, officer, director, employee or agent of the
Securities Administrator, the Owner Trustee in its individual capacity, any
holder of a beneficial interest in the Issuer, the Securities Administrator, the
Owner Trustee or the Indenture Trustee or of any successor or assign of the
Indenture Trustee or the Owner Trustee in its individual capacity, except as any
such Person may have expressly agreed (it being understood that the Indenture
Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity. For all purposes of this Indenture, in the performance of
any duties or obligations of the Issuer hereunder, the Owner Trustee shall be
subject to, and entitled to the benefits of, the terms and provisions of Article
VI, VII and VIII of the Trust Agreement.

         Section 10.15 NO PETITION. The Indenture Trustee and the Securities
Administrator, by entering into this Indenture, each Noteholder, by accepting a
Note and each Certificateholder, by accepting a Certificate, hereby covenant and
agree that they will not at any time prior to one year from the date of
termination hereof, institute against the Depositor or the Issuer, or join in
any institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law
in connection with any obligations relating to the Notes, this Indenture or any
of the Basic Documents; provided however, that nothing herein shall prohibit the
Indenture Trustee from filing proofs of claim in any proceeding.

         Section 10.16 INSPECTION. The Issuer agrees that, at its expense, on
reasonable prior notice, it shall permit any representative of the Indenture
Trustee or the Securities Administrator, during the Issuer's normal business
hours, to examine all the books of account, records, reports and other papers of
the Issuer, to make copies and extracts therefrom, to cause such books to be
audited by Independent certified public accountants, and to discuss the Issuer's
affairs, finances and accounts with the Issuer's officers, employees, and
Independent certified public accountants, all at such reasonable times and as
often as may be reasonably requested. The Indenture Trustee shall cause its
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
such disclosure is consistent with its obligations hereunder.

                  BEAR STEARNS ARM TRUST 2005-2 (the "Issuer"), a Delaware
statutory trust, for value received, hereby promises to pay to Cede & Co. or
registered assigns, the principal sum of $[____________________] in monthly
installments on the twenty-fifth day of each month or, if such day is not a
Business Day, the next succeeding Business Day (each a "Payment Date"),
commencing in March 2005 and ending on or before the Payment Date occurring in
[__________ 20___] (the "Final Scheduled Payment Date") and to pay interest on
the Note Principal Balance of this Note (this "Note") outstanding from time to
time as provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2005-2 (the "Notes"), issued under an Indenture
dated as of February 28, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, National Association, as Securities Administrator and U.S. Bank National
Association, as indenture trustee (the "Indenture Trustee", which term includes
any successor Indenture Trustee under the Indenture) and 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

                                      A-1-3

<PAGE>

to this Note shall be equal to this Note's pro rata share of the aggregate
payments on all Class A- [1][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 A-[1][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 A-[1][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 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.

<PAGE>

         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,
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.

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

         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

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.

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

         BEAR STEARNS ARM TRUST 2005-2 (the "Issuer"), a Delaware statutory
trust, for value received, hereby promises to pay to Bear, Stearns Securities
Corp. or registered assigns, the principal sum of $[________]in monthly
installments on the twenty-fifth day of each month or, if such day is not a
Business Day, the next succeeding Business Day (each a "Payment Date"),
commencing in March 2005 and ending on or before the Payment Date occurring in
March 2035 (the "Final Scheduled Payment Date") and to pay interest on the Note
Principal Balance of this Note (this "Note") outstanding from time to time as
provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2005-2 (the "Notes"), issued under an Indenture
dated as of February 28, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, N.A., as securities administrator and U.S. 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

                                      A-2-3

<PAGE>

be equal to this Note's pro rata share of the aggregate payments on all Class
A-[3][4] 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 A-[3][4] 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 A-[3][4] 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

                                      A-2-4

<PAGE>

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.

         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 A-[3][4] Note or any interest therein shall
be made to any Person unless the Indenture Trustee and the Note Registrar are
provided with an Opinion of Counsel which establishes to the satisfaction of the
Indenture Trustee and the Note Registrar that the purchase of a Class A-[3][4]
Note is permissible under applicable law, will not constitute or result in any
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Issuer, the Seller, the Owner Trustee, the Indenture Trustee, the
Master Servicer, any Servicer or the Note Registrar to any obligation or
liability (including obligations or liabilities under ERISA or Section 4975 of
the Code) in addition to those undertaken in this Agreement, which Opinion of
Counsel shall not be an expense of the Issuer, the Seller, the Owner Trustee,
the Indenture Trustee, the Securities Administrator, the Master Servicer, any
Servicer and the Note Registrar. In lieu of such Opinion of Counsel, a Person
acquiring a Class A-[3][4] Note may provide a certification in the form attached
to the Indenture, which the Depositor, the Owner Trustee, the Certificate
Registrar and the Master Servicer may rely upon without further inquiry or
investigation.

<PAGE>

         No transfer of this Class A-[3][4] Note or any interest therein shall
be made to any Person , and the Note Registrar shall refuse to register any such
transfer, so long as the Class A-1 Notes and Class A-2 Notes, and any Class A-3
Notes, Class A-4 Notes or Subordinate Notes with respect to which a "will be
debt" opinion has been rendered by nationally recognized tax counsel, are
outstanding, unless (A) a "will be debt" opinion shall have been rendered by
nationally recognized tax counsel with respect to it and furnished to the
Securities Administrator, or (B) 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") or a qualified REIT subsidiary ("QRS") within the
meaning of Section 856(a) or 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 and Class A-3 Notes, Class A-4 Notes and Subordinate Notes
(other than any Class A-3 Notes, Class A-4 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 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; provided that (x) this Class A-[3][4] 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
A-[3][4] 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,
the Securities Administrator, the Owner Trustee and the Indenture Trustee 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, 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

                                      A-2-6

<PAGE>

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
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.

dated as of February 28, 2005 (the "Indenture"), among the Issuer, Wells Fargo
Bank, N.A. as securities administrator and U.S. 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 interest on this Note will be made on each Payment Date to
the Noteholder of record as of the related Record Date. The "Notional Amount" of
this Note as of any date of determination shall be calculated as set forth under
the Indenture.

time of payment is legal tender for payment of public and private debts. All

provided in the Indenture.

         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

         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 X-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 X-1 Notes pursuant to the Indenture
and the rights conveyed to the Issuer under the Indenture.

         Any payment of 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 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 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. 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 and interest on the Notes as if they had not
been declared due and payable.

         The failure to pay Accrued Note Interest on the Class X-1 Notes, 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

                                      A-3-4

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 X-1 Note or any interest therein shall be
made to any Person unless the Indenture Trustee and the Note Registrar are
provided with an Opinion of Counsel which establishes to the satisfaction of the
Indenture Trustee and the Note Registrar that the purchase of a Class X-1 Note
is permissible under applicable law, will not constitute or result in any
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Depositor, the Owner Trustee, the Indenture Trustee, the Securities
Administrator, the Note Registrar, any Servicer or the Master Servicer to any
obligation or liability (including obligations or liabilities under ERISA or
Section 4975 of the Code) in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Issuer, the Seller, the
Owner Trustee, the Indenture Trustee, the Master Servicer or the Note Registrar.
In lieu of such Opinion of Counsel, a Person acquiring a Class X-1 Note may
provide a certification in the form attached to the Indenture, which the
Indenture Trustee and the Note Registrar may rely upon without further inquiry
or investigation.

         No transfer of this Class X-1 Note or any interest therein shall be
made to any Person , and the Note Registrar shall refuse to register any such
transfer, so long as the Class A-1 Notes and Class A-2 Notes, and any Class A-3
Notes, Class A-4 Notes or Subordinate Notes with respect to which a "will be
debt" opinion has been rendered by nationally recognized tax counsel, are
outstanding, unless (A) a "will be debt" opinion shall have been rendered by
nationally recognized tax counsel with respect to it and furnished to the
Securities Administrator, or (B) 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") or a qualified REIT subsidiary ("QRS") within the
meaning of Section 856(a) or 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 and Class A-3 Notes, Class A-4 Notes and Subordinate Notes
(other than any Class A-3 Notes, Class A-4 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 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; provided that (x) this Class X-1 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 X-1

                                      A-3-5

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, the Securities
Administrator, the Owner Trustee and the Indenture Trustee 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

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

Issuer, 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

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.

NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE

         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

                                      A-4-3

<PAGE>

payment of public and private debts. All payments made by the Issuer with
respect to this Note shall be equal to this Note's pro rata share of the
aggregate payments on all Class B-[1][2][3][4][5][6] 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][4][5][6] 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][4][5][6] 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.

<PAGE>

         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,
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 B-[1][2][3][4][5][6] Note or any interest
therein shall be made to any Person unless the Indenture Trustee and the Note
Registrar are provided with an Opinion of Counsel which establishes to the
satisfaction of the Indenture Trustee and the Note Registrar that the purchase
of a Class B-[1][2][3][4][5][6] Note is permissible under applicable law, will
not constitute or result in any prohibited transaction under ERISA or Section
4975 of the Code and will not subject the Issuer, the Seller, the Owner Trustee,
the Indenture Trustee, the Master Servicer, any Servicer or the Note Registrar
to any obligation or liability (including obligations or liabilities under ERISA
or Section 4975 of the Code) in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Issuer, the Seller, the
Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master
Servicer, any Servicer and the Note Registrar. In lieu of such

                                      A-4-5

<PAGE>

Opinion of Counsel, a Person acquiring a Class B-1 Note may provide a
certification in the form attached to the Indenture, which the Depositor, the
Owner Trustee, the Certificate Registrar and the Master Servicer may rely upon
without further inquiry or investigation.

         No transfer of this Class B-[1][2][3][4][5][6] Note or any interest
therein shall be made to any Person, and the Note Registrar shall refuse to
register any such transfer, so long as the Class A-1 Notes and Class A-2 Notes,
and any Class A-3 Notes, Class A-4 Notes or Subordinate Notes with respect to
which a "will be debt" opinion has been rendered by nationally recognized tax
counsel, are outstanding, unless (A) a "will be debt" opinion shall have been
rendered by nationally recognized tax counsel with respect to it and furnished
to the Securities Administrator, or (B) 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") or a qualified REIT subsidiary ("QRS") within the
meaning of Section 856(a) or 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 and Class A-3 Notes, Class A-4 Notes and Subordinate Notes
(other than any Class A-3 Notes, Class A-4 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 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; provided that (x) this Class B-[1][2][3][4][5][6] 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][4][5][6] 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, the Securities Administrator, the Owner Trustee and the Indenture
Trustee 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

                                      A-4-6

<PAGE>

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
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.

             Description of Rule 144A Securities, including numbers:

         --------------------------------------------------------------

         --------------------------------------------------------------

         --------------------------------------------------------------

         --------------------------------------------------------------

                  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 February 28, 2005, among Bear Stearns ARM Trust
2005-2, as Issuer, and Wells Fargo Bank, National Association, as Securities
Administrator and U.S. Bank National Association, as Indenture Trustee, as
follows:

                           a. The Buyer understands that the Rule 144A
         Securities have not been registered under the 1933 Act or the
         securities laws of any state.

                           b. The Buyer considers itself a substantial,
         sophisticated institutional investor having such knowledge and
         experience in financial and business matters that it is capable of
         evaluating the merits and risks of investment in the Rule 144A
         Securities.

                                       C-1

<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. 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 either (1) the Buyer is (A) not an
employee benefit plan (within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")), or a plan (within
the meaning of Section 4975(e)(1) of the Internal Revenue Code of 1986
("Code")), which (in either case) is subject to ERISA or Section 4975 of the
Code (both a "Plan"), and (B) is not directly or indirectly purchasing the Rule
144A Securities on behalf of, as investment manager of, as named fiduciary of,
as trustee of, or with "plan assets" of a Plan, or (2) the Buyer understands
that registration of transfer of any Rule 144A Securities to any Plan, or to any
Person acting on behalf of any Plan, will not be made unless such Plan delivers
an opinion of its counsel, addressed and satisfactory to the Certificate
Registrar, the Owner Trustee, the Indenture Trustee, the Master Servicer and the

account of a third party (including any separate account) in reliance on Rule
144A, the Buyer will only purchase for the account of a third party that at the
time is a "qualified institutional buyer" within the meaning of Rule 144A. In
addition, the Buyer agrees that the Buyer will not purchase securities for a
third party unless the Buyer has obtained a current representation letter from
such third party or taken other appropriate steps contemplated by Rule 144A to
conclude that such third party independently meets the definition of "qualified
institutional buyer" set forth in Rule 144A.

            7. The Buyer will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Buyer's purchase of Rule 144A Securities will
constitute a reaffirmation of this certification as of the date of such
purchase.

                 ---------------------------------------------------------------

Gentlemen:

         This certification is being made by ____________________ (the
"Transferor") in connection with the proposed Transfer to _____________________
(the "Transferee") of the [Class A Notes][Class X-1 Notes] [Class B Notes] (the
"Notes") issued pursuant to the Indenture, dated February 28, 2005, being
referred to herein as the "Indenture") among Bear Stearns ARM Trust 2005- 2, as
issuer, Wells Fargo Bank, National Association, as securities administrator and
U.S. Bank National Association as indenture trustee (the "Indenture"). Initially
capitalized terms used but not defined herein have the meanings assigned to them
in the Indenture. The Transferor hereby certifies, represents and warrants to,
and covenants with, the Owner Trustee and the Indenture Trustee that:

         Neither the Transferor nor anyone acting on its behalf has (a) offered,
pledged, sold, disposed of or otherwise transferred any Note, any interest in
any Note or any other similar security to any person in any manner, (b) has
solicited any offer to buy or to accept a pledge, disposition or other transfer

in any manner, (d) has made any general solicitation by means of general
advertising or in any other manner, or (e) has taken any other action, that (as
to any of (a) through (e) above) would constitute a distribution of the Notes

that would require registration or qualification pursuant thereto. The
Transferor will not act in any manner set forth in the foregoing sentence with
respect to any Note. The Transferor has not and will not sell or otherwise
transfer any of the Notes, except in compliance with the provisions of the

                  Any scheduled reduction to the Senior Prepayment Percentage
for the related Senior Notes shall not be made as of any Payment Date unless, as
of the last day of the month preceding such Payment Date (1) the aggregate
Scheduled Principal Balance of the Mortgage Loans delinquent 60 days or more
(including for this purpose any such Mortgage Loans in foreclosure and
bankruptcy and such Mortgage Loans with respect to which the related mortgaged
property has been acquired by the Grantor Trust) averaged over the last six
months, as a percentage of the aggregate Note Principal Balance of the
Subordinate Notes does not exceed 50% and (2) cumulative Realized Losses on the
Mortgage Loans do not exceed (a) 30% of the aggregate Note Principal Balance of
the Original Subordinate Principal Balance if such Payment Date occurs between
and including March 2012 and February 2013, (b) 35% of the Original Subordinate
Principal Balance if such Payment Date occurs between and including March 2013
and February 2014, (c) 40% of the Original Subordinate Principal Balance if such

February 2015, (d) 45% of the Original Subordinate Principal Balance if such
Payment Date occurs between and including March 2015 and February 2016, and (e)
50% of the Original Subordinate Principal Balance if such Payment Date occurs
during or after March 2016.

                  In addition, if on any Payment Date the current weighted
average of the Subordinate Percentages is equal to or greater than two times the
weighted average of the initial Subordinate Percentage, and (a) the aggregate
Scheduled Principal Balance of the Mortgage Loans delinquent 60 days or more
(including for this purpose any such Mortgage Loans in foreclosure and
bankruptcy and such Mortgage Loans with respect to which the related mortgaged
property has been acquired by the Grantor Trust), averaged over the last six
months, as a percentage of the aggregate Note Principal Balance of the
Subordinate Notes does not exceed 50% and (b)(i) on or prior to the Payment Date
occurring in February 2008, cumulative Realized Losses on the Mortgage Loans as
of the end of the related Prepayment Period do not exceed 20% of the Original
Subordinate Principal Balance and (ii) after the Payment Date occurring in
February 2008, cumulative Realized Losses on the Mortgage Loans as of the end of
the related Prepayment Period do not exceed 30% of the Original Subordinate
Principal Balance, then, in each case, the Senior Prepayment Percentage for the
Senior Notes for such Payment Date will equal the Senior Percentage for such
Classes of Senior Notes; provided, however, if on such Payment Date the current
weighted average of the Subordinate Percentages is equal to or greater than two
times the weighted average of the initial Subordinate Percentages on or prior to
the Payment Date occurring in February 2008 and the above delinquency and loss
tests are met, then the Senior Prepayment Percentage for the Senior Notes for
such Payment Date, will equal the Senior Percentage for such Classes of Senior
Notes plus 50% of the related Subordinate Percentage on such Payment Date.

                  Notwithstanding the foregoing, if on any Payment Date, the
percentage, the numerator of which is the aggregate Note Principal Balance of
the Senior Notes of a Note Group immediately preceding such Payment Date, and
the denominator of which is the Scheduled Principal Balance of the Mortgage
Loans in the related Loan Group as of the beginning of the related Due Period,
exceeds such percentage as of the Cut-off Date, then the related Senior
Prepayment Percentage for such Payment Date will equal 100%.

          without consent of Radica USA, or (ii) twelve (12) months after the

<PAGE>

          in the event of a Termination/Change in Control (unless Section 6(f)
          of this Agreement applies, in which case this Section 6(c) shall not
          apply to Employee's Stock Options, restricted stock and restricted
          stock units) or the Total Disability of Employee (each of such
          applicable dates being called a "Determination Date"), Employee shall

         5. Sections 6(d), (e) and (f) of the Employment Agreement are hereby
amended in their entirety to read as follows:

          (d) In any event each Stock Option shall expire to the extent not
          previously exercised on the tenth anniversary of the Grant Date.
          Otherwise, Employee may at any time within ninety (90) days following
          the Determination Date, exercise her right to purchase stock subject
          to the Stock Options, but subject to the foregoing provisions
          respecting vesting and forfeitures. Restricted Stock, and restricted
          stock units, if not forfeited, shall be deliverable to Employee upon
          its applicable vesting date, free of the previously existing
          restrictions, but subject to applicable state and federal securities
          laws.

          (e) Employee shall have no right to sell, alienate, mortgage, pledge,
          gift or otherwise transfer the Stock Options, the Restricted Stock or
          any restricted stock units or any rights thereto, except by will or by
          the laws of descent and distribution, and except pursuant to
          applicable state and federal securities laws and except as
          specifically contemplated herein.

          (f) Upon the occurrence of a Change in Control under the Omnibus Plan,
          all of Employee's then outstanding stock options, restricted stock,
          and restricted stock units in Radica shall vest and become immediately
          exercisable. If Employee is terminated by Radica or Radica USA without
          Cause after a definitive agreement for a transaction that would
          constitute a Change in Control as described in the Omnibus Plan has
          been approved by the shareholders of Radica, but before such
          transaction is consummated, Employee's stock options, restricted
          stock, and restricted stock units in Radica shall vest on the date of
          such termination without Cause. Income realized by Employee as a
          result of the acceleration of vesting of equity compensation or
          otherwise resulting from a Termination/Change in Control is
          specifically paid in consideration of post-employment restrictions of
          Section 7 hereunder.

         6. Section 13 of the Employment Agreement is hereby amended in its
entirety to read as follows:

          13. MODIFICATIONS OR DISCHARGE. This Agreement shall not be deemed
          waived, changed, modified, discharged or terminated in whole or in
          part, except as expressly provided for herein or by written instrument
          signed by all parties hereto. Each party agrees to make any
          modifications to this Agreement, including changing the timing of
          payments hereunder, as may be reasonably necessary to comply with
          Section 409A of the Internal Revenue Code.

         7. Section 16 of the Employment Agreement is hereby amended in its
entirety to read as follows:

          REIMBURSEMENT OF EXPENSES. After a Change in Control or a Termination
          for Cause later determined to be a Termination Without Cause, if any
          dispute shall arise under this Agreement involving termination of
          Employee's employment with Radica USA or involving the failure or
          refusal of Radica USA to perform fully in accordance with the terms
          hereof, Radica USA shall reimburse Employee, on a current basis, for
          all reasonable legal fees and expenses, if any, incurred by Employee
          in connection with such contest or dispute (regardless of the result
          thereof), regardless of whether Employee's claim is upheld by a court
          of competent jurisdiction; provided, however, Employee shall be
          required to repay any such amounts to Radica USA to the extent that a
          court issues a final and non-appealable order setting forth the
          determination that the position taken by Employee was frivolous or
          advanced by Employee in bad faith.

                                       4
