                                    COVENANTS

      Section 3.01 Collection of Payments with respect to the Mortgage Loans.
The Indenture Trustee shall maintain the Payment Account established pursuant to
Section 3.05 of the Sale and Servicing Agreement in accordance with the
requirements of such Section. The Indenture Trustee shall make all payments of
principal of and interest on the Notes, subject to Section 3.03 herein, as
provided in Section 3.05 of the Sale and Servicing Agreement from monies on
deposit in the Payment Account.

      Section 3.02 Maintenance of Office or Agency. The Indenture Trustee will
maintain or cause to be maintained at its expense an office or offices or agency
or agencies in _________ where Notes may be surrendered for registration of
transfer or exchange. The Indenture Trustee initially designates its offices at
_________________________, as offices for such purposes. The Indenture Trustee
will give prompt written notice to the Noteholders of any change in such
location of any such office or agency.

      Section 3.03 Money for Payments To Be Held in Trust; Paying Agent. (a) As
provided in Section 3.01, all payments of amounts due and payable with respect
to any Notes that are to be made from amounts withdrawn from the Payment Account
pursuant to Section 3.01 shall be made on behalf of the Issuing Entity by the
Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from the
Payment Account for payments of Notes shall be paid over to the Issuing Entity
except as provided in this Section 3.03. The Issuing Entity hereby appoints the
Indenture Trustee as its Paying Agent.

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

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

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

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

            (iv) immediately resign as Paying Agent and forthwith pay to the
      Indenture Trustee all sums held by it in trust for the payment of Notes if
      at any time it ceases to meet the standards required to be met by a Paying
      Agent at the time of its appointment;

                                       6
<PAGE>

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

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

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

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

      Section 3.04 Existence. The Issuing Entity will keep in full effect its
existence, rights and franchises as a statutory trust under the laws of the
State of Delaware (unless it becomes, or any successor Issuing Entity hereunder
is or becomes, organized under the laws of any other state or of the United
States of America, in which case the Issuing Entity will keep in full effect its
existence, rights and franchises under the laws of such other jurisdiction) and
will obtain and preserve its qualification to do business in each jurisdiction
in which such qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Mortgage Loans and each other
instrument or agreement included in the Trust Estate.

      Section 3.05 Protection of Trust Estate. (a) The Issuing Entity will from
time to time prepare, execute and deliver all such supplements and amendments

statements, continuation statements, instruments of further assurance and other
instruments, and will take such other action necessary or advisable to:

            (i) maintain or preserve the lien and security interest (and the
      priority thereof) of this Indenture or carry out more effectively the
      purposes hereof;

            (ii) perfect, publish notice of or protect the validity of any Grant
      made or to be made by this Indenture;

            (iii) cause the Indenture Trustee or Master Servicer to enforce any
      of the rights to the Mortgage Loans; or

            (iv) preserve and defend title to the Trust Estate and the rights of
      the Indenture Trustee and the Noteholders in such Trust Estate against the
      claims of all persons and parties.

      (b) Except as otherwise provided in this Indenture, the Indenture Trustee
shall not remove any portion of the Trust Estate that consists of money or is
evidenced by an instrument, certificate or other writing from the jurisdiction
in which it was held at the date of the most recent Opinion of Counsel delivered
pursuant to Section 3.06 hereof (or from the jurisdiction in which it was held
as described in the Opinion of Counsel delivered on the Closing Date pursuant to
Section 3.06(a) hereof, or if no Opinion of Counsel has yet been delivered
pursuant to Section 3.06(b) hereof, unless the Indenture Trustee shall have
first received an Opinion of Counsel to the effect that the lien and security
interest created by this Indenture with respect to such property will continue
to be maintained after giving effect to such action or actions).

      The Issuing Entity hereby designates the Indenture Trustee its agent and
attorney-in-fact to sign any financing statement, continuation statement or
other instrument required to be signed pursuant to this Section 3.05 upon the
Issuing Entity's preparation thereof and delivery to the Indenture Trustee.

      Section 3.06 Opinions as to Trust Estate. (a) On the Closing Date, the

action has been taken with respect to the recording and filing of this
Indenture, any indentures supplemental hereto, and any other requisite
documents, and with respect to the execution and filing of any financing
statements and continuation statements, as are necessary to perfect and make
effective the lien and first priority security interest in the Collateral and
reciting the details of such action, or stating that, in the opinion of such
counsel, no such action is necessary to make such lien and first priority
security interest effective.

      (b) On or before April 15 in each calendar year, beginning in ____, the

security interest in the Collateral and reciting the details of such action or

performing its duties under this Indenture, and any performance of such duties
by a Person identified to the Indenture Trustee in an Officer's Certificate of

      (c) The Issuing Entity will not take any action or permit any action to be
taken by others which would release any Person from any of such Person's
covenants or obligations under any of the documents relating to the Mortgage
Loans, or under any instrument included in the Trust Estate, or which would
result in the amendment, hypothecation, subordination, termination or discharge
of, or impair the validity or effectiveness of, any of the documents relating to
the Mortgage Loans or any such instrument, except such actions as the Master
Servicer is expressly permitted to take in the Sale and Servicing Agreement. The

the Issuing Entity to direct the actions of the Master Servicer pursuant to the
Sale and Servicing Agreement.

      (d) The Issuing Entity may retain an administrator and may enter into
contracts with other Persons for the performance of the Issuing Entity's

            (ii) claim any credit on, or make any deduction from the principal

            (iii) (A) permit the validity or effectiveness of this Indenture to
      be impaired, or permit the lien of this Indenture to be amended,
      hypothecated, subordinated, terminated or discharged, or permit any Person
      to be released from any covenants or obligations with

                                       9
<PAGE>

      respect to the Notes under this Indenture except as may be expressly
      permitted hereby, (B) permit any lien, charge, excise, claim, security
      interest, mortgage or other encumbrance (other than the lien of this

      the Trust Estate or any part thereof or any interest therein or the

      been made under such Authorized Officer's supervision; and

            (ii) to the best of such Authorized Officer's knowledge, based on
      such review, the Issuing Entity has complied with all conditions and
      covenants under this Indenture throughout such year, or, if there has been
      a default in its compliance with any such condition or covenant,
      specifying each such default known to such Authorized Officer and the
      nature and status thereof.

      Section 3.10 Representations and Warranties Concerning the Mortgage Loans.

Mortgage Loans, has the benefit of the representations and warranties made by
the Seller in the Sale and Servicing Agreement and the Subsequent Transfer
Agreement concerning the Seller the Initial Mortgage Loans and the Subsequent
Mortgage Loans to the same extent as though such representations and warranties
were made directly to the Indenture Trustee. If a Responsible Officer of the
Indenture Trustee has actual knowledge of any breach of any representation or
warranty made by the Seller in the Sale and Servicing Agreement, the Indenture
Trustee shall promptly notify the Seller of such finding and such party's
obligation to cure such defect or repurchase or substitute for the related
Initial Mortgage Loan or Subsequent Mortgage Loan.

      Section 3.11 Amendments to Sale and Servicing Agreement. The Issuing

cause the any REMIC to fail to qualify as a REMIC at any time that any Notes are
outstanding.

Account, as well as its bailee in holding any related document in the Mortgage
File released to the Master Servicer, and any other items constituting a part of
the Trust Estate which from time to time come into the possession of the Master
Servicer. It is intended that, by the Master Servicer's acceptance of such

Loans, will be deemed to have possession of such document, such monies and such
other items for purposes of Section 9-305 of the Uniform Commercial Code of the
state in which such property is held by the Master Servicer. The Indenture
Trustee shall not be liable with respect to such documents, monies or items

(taking into account not only the general definition of the term "investment
company" but also any available exceptions to such general definition);

      Section 3.24 Certain Representations Regarding the Trust Estate.

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

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

            (ii) In each case, within the meaning of the applicable UCC: (A) the
      Collateral described in clauses (a) through (c) constitutes "deposit
      accounts" or "instruments," as applicable; (B) the Collateral described in
      clause (d) constitutes "real property;"(C) the Collateral described in
      clause (e) constitutes "insurance;" and (D) the Collateral described in
      clauses (e), (f) and (g) constitute "general intangibles."

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

                                       14
<PAGE>

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

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

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

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

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

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

      Section 3.25 The Pre-Funding Account.

      (a) The Indenture Trustee shall establish and maintain, on behalf of the
Noteholders, the Pre-Funding Account. On the Closing Date the Depositor shall
remit the Original Pre-Funded Amount to the Indenture Trustee for deposit in the
Pre-Funding Account.

      On each Subsequent Transfer Date, upon satisfaction of the conditions in
Section 2.01 of the Sale and Servicing Agreement, the Indenture Trustee shall
withdraw from the Pre-Funding Account 100% of the aggregate of the Cut-off Date
Principal Balances of the Subsequent Mortgage Loans sold to the Trust Fund on
the Subsequent Transfer Date and pay that amount to the order of the Seller.

      On the Business Day before the Payment Date following the end of the
Funding Period, the Indenture Trustee shall (i) withdraw the unused Pre-Funded
Amount from the Pre-Funding Account, (ii) promptly deposit such amount in the
Payment Account, and (iii) pay such amount to the Notes on the Payment Date
pursuant to Section 4.02.

                                       15
<PAGE>

      The amount deposited in the Payment Account pursuant to the preceding
paragraph shall be net of any investment earnings on the amounts on deposit in
the Pre-Funding Account.

      (b) The Indenture Trustee shall invest funds in the Pre-Funding Account,
as directed by the Seller, in Permitted Investments, which shall mature not
later than the Business Day immediately preceding the first Payment Date that
follows the date of such investment, and which shall not be sold or disposed of
prior to its maturity. All Permitted Investments in the Pre-Funding Account
shall be made in the name of the Indenture Trustee, for the benefit of the
Seller. The amount of any losses incurred in the Pre-Funding Account in respect
of any such investments shall be paid by the Seller to the Indenture Trustee for
deposit into the Pre-Funding Account out of the Seller's own funds immediately
as realized. The Indenture Trustee shall not be liable for the amount of any
loss incurred in respect of any investment or lack of investment of funds held

Trustee with the related Remittance Report.

      (b) On each Payment Date following the application of all amounts
distributable on such date, to the extent the aggregate Stated Principal Balance

               THE NOTES; SATISFACTION AND DISCHARGE OF INDENTURE

      Section 4.01 The Notes. Each Class of Book-Entry Notes shall be registered
in the name of a nominee designated by the Depository. Beneficial Owners will
hold interests in the Book-Entry Notes through the book-entry facilities of the
Depository in minimum initial Note Principal Balances of $______ and integral
multiples of $_____ in excess thereof.

      The Indenture Trustee 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
Indenture Trustee 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 Issuing Entity and
the Indenture Trustee, 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 Indenture Trustee with the approval of the Issuing Entity 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 Issuing
Entity by the Owner Trustee, not in its individual capacity but solely as Owner
Trustee, authenticated by the Indenture Trustee and delivered by the Indenture
Trustee to or upon the order of the Issuing Entity.

                  with respect to which there remains any unpaid Net Rate
                  Carryover Amount (after the distribution based on Note
                  Principal Balances), pro rata, based on the amount of such
                  unpaid Net Rate Carryover Amount, to the extent needed to pay
                  any remaining Net Rate Carryover Amount for each such Class;

                  Unpaid Realized Loss Amount for such Class;

                  (F) from remaining Available Funds from all of the Loan
                  Groups, to the Class M-1 Notes, in an amount equal to any Net
                  Rate Carryover Amount for such Class;

                  (G) concurrently, to each Class of Class IO Notes, an amount
                  allocable to interest equal to the related Class Optimal
                  Interest Distribution Amount for such Payment Date, any
                  shortfall being allocated among such Classes in proportion to
                  the amount of the Class Optimal Interest Distribution Amount
                  that would have been distributed in the absence of such
                  shortfall;

                  (H) from remaining Available Funds from all of the Loan
                  Groups, to the Class M-2 Notes, an amount allocable to
                  interest equal to the Class Optimal Interest Distribution
                  Amount for such Class for such Payment Date;

                  Groups, to the Class M-2 Notes, an amount allocable to

                  M-1 Notes),

                  on a pro rata basis, based on the amount of Unpaid Realized
                  Loss Amount for such Classes, in an amount equal to the Unpaid
                  Realized Loss Amount for each such Class;

                  (U) from remaining Available Funds from all Loan Groups, to
                  the Classes of to the Classes of Subordinate Notes (other than
                  the Class IO Notes and Class M-1 Notes), on a pro rata basis,
                  based on the Note Principal Balances thereof, to the extent
                  needed to pay any Net Rate Carryover Amount for each such
                  Class; provided that any related Available Funds remaining
                  after such allocation to pay Net Rate Carryover Amount based
                  on the Note Principal Balances of these Notes will be
                  distributed to each such Class of Notes with respect to which
                  there remains any unpaid Net Rate Carryover Amount (after the
                  distribution based on Note Principal Balances), pro rata,
                  based on the amount of such unpaid Net Rate Carryover, to the
                  extent needed to pay any remaining Net Rate Carryover Amount
                  for each such Class; and

                  (V) any remaining amounts to the Certificate Paying Agent, as
                  designee of the Issuing Entity, for the benefit of the Holders
                  of the Trust Certificates.

      (b) [Reserved]

      (c) [Reserved]

      (d) On each Payment Date, Net Interest Shortfalls for a Loan Group on any
Payment Date will be allocated in the following order: (1) to the Owner Trust
Certificates, in reduction of any amounts otherwise distributable to the Owner
Trust Certificates pursuant to Section 4.02(a)(7)(V), (2) to the Class B-5,
Class B-4, Class B-3, Class B-2, Class B-1 and Class M-2 Notes, in that order,
in reduction of the amount referred to in clause (i) of the definition of Class
Optimal Interest Distribution Amount for each Class of Notes for such Payment
Date, (3) to the related Class IO Notes, in reduction of the amount referred to
in clause (i) of the definition of Class Optimal Interest Distribution Amount
for each Class of Notes for such Payment Date, (4) to the non-related Classes of
Class IO Notes, in reduction of the amount referred to in clause (i) of the
definition of Class Optimal Interest Distribution Amount for each Class of Notes
for such Payment Date, (5) to the Class M-1 Notes, in reduction of the amount
referred to in clause (i) of the definition of Class Optimal Interest
Distribution Amount for each Class of Notes for such Payment Date and (6) to the
classes of related Senior Notes, on a pro rata basis, in reduction of the amount
referred to in clause (i) of the definition of Class Optimal Interest
Distribution Amount for each Class of Notes for such Payment Date.

      [The amount referred to in clause (i) of the definition of Class Optimal
Interest Distribution Amount for each Class of Notes for such Payment Date shall
be reduced for each Class of Senior Notes of a Senior Note Group and each Class
of Subordinated Notes by (i) the related Class' pro rata share of Net Interest
Shortfalls for such Loan Group based (x) with respect to a Class of Senior
Notes, on the related Class Optimal Interest Distribution Amount for such
Payment Date, and (y) with respect to a Class of Subordinated Notes on and prior
to the

                                       24
<PAGE>

SeniorTermination Date, on the Assumed Interest Amount or after such Senior
Termination Date, on the related Class Optimal Interest Distribution Amount for
such Payment Date, without taking into account such Net Interest Shortfalls.]

      (e) Notwithstanding the priority and allocation contained in Section
4.02(a)(7), if with respect to any Class of Subordinated Notes on any Payment
Date (other than the Class of Subordinated Notes then outstanding with the
highest priority of distribution) the sum of the related Class Subordination
Percentages of such Class and of all Classes of Subordinated Notes which have a
higher numerical Class designation than such Class (the "Applicable Credit
Support Percentage") is less than the Original Applicable Credit Support
Percentage for such Class, no distribution of Principal Prepayments will be made
to any such Classes (the "Restricted Classes") and the amount of such Principal
Prepayments otherwise distributable to the Restricted Classes shall be
distributed to any Classes of Subordinated Notes having lower numerical Class
designations than such Class, pro rata, based on their respective Note Principal
Balances immediately prior to such Payment Date and shall be distributed in the
sequential order provided in Section 4.02(a)(7).

      (f) If Subsequent Recoveries have been received with respect to a
Liquidated Mortgage Loan, the amount of such Subsequent Recoveries will be
applied sequentially, in the order of payment priority to increase the Note
Principal Balance of each Class of Notes to which Realized Losses have been
allocated, but in each case by not more than the amount of Realized Losses
previously allocated to that Class of Notes pursuant to Section 3.28. Holders of
such Notes will not be entitled to any payment in respect of the Class Optimal
Interest Distribution Amount 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 pro rata to the Note Principal Balance of each
Note of such Class.

      (g) On each Payment Date prior to the earlier of the Senior Credit Support
Depletion Date and the Senior Termination Date, but after a Senior Termination
Date, the Trustee shall distribute the principal portion of Available Funds on
the Mortgage Loans relating to the Senior Notes that will have been paid in full
to the holders of the Senior Notes of the other Senior Note Groups, pro rata,
based on Note Principal Balance Balances, provided, however, that the Indenture
Trustee shall not make such distribution on such Payment Date if (a) the
Aggregate Subordinated Percentage for such Payment Date is greater than or equal
to 200% of such Aggregate Subordinated Percentage as of the Closing Date and (b)
the average aggregate Stated Principal Balance of the Mortgage Loans delinquent
60 days or more over the last six months, as a percentage of the aggregate Note
Principal Balance of the Subordinated Certificates, is less than 50%.

      If on any Payment Date the Note Principal Balance of Senior Notes in a
Senior Note Group immediately prior to each Payment Date is greater than the
aggregate Stated Principal Balance of the Mortgage Loans in the related Loan
Group (the "Undercollateralized Group"), then the Indenture Trustee shall apply
the Available Funds of the other Loan Group(s) that are not undercollateralized
(each, an "Overcollateralized Group"), as follows:

      (1) to add to the Available Funds of the Undercollateralized Groups an
amount equal to the lesser of (a) one month's interest on the Transfer Payment
Received of the

                                       25
<PAGE>

Undercollateralized Group at the Weighted Average Adjusted Net Mortgage Rate
applicable to the Undercollateralized Group and (b) Available Funds of the
Overcollateralized Group(s) remaining after making distributions to the
Certificates of the Overcollateralized Group(s) on such Payment Date pursuant to
Section 4.02; and

      (2) to the Senior Notes of the Undercollateralized Groups, to the extent
of the principal portion of Available Funds of the Overcollateralized Groups
remaining after making distributions to the Senior Notes of the
Overcollateralized Groups on such Payment Date pursuant to Section 4.02, until
the Note Principal Balance of the Senior Notes of such Undercollateralized
Groups equals the aggregate Stated Principal Balance of the Mortgage Loans in
the related Loan Group.

      If more than one Overcollateralized Group exists on any Payment Date,
reductions in the Available Funds of such groups to make the payments required
to be made pursuant to this Section 4.02(g) on such Payment Date shall be made
pro rata, based on the amount of remaining Available Funds for each such
Overcollateralized Group. If more than one Undercollateralized Group exists on
any Payment Date, the payments required to be made pursuant to this Section
4.02(g) on such Payment Date shall be made pro rata, based on the amount of
payments required to be made to the Undercollateralized Groups.

      The payment received by the Undercollateralized Group (including the
interest thereon as provided in (1) above) is referred to as a "Transfer Payment
Received." The payment made by the Overcollateralized Group (including the
interest thereon as provided in (1) above) is referred to as a "Transfer Payment
Made."

      Section 4.03 Registration of and Limitations on Transfer and Exchange of
Notes; Appointment of Note Registrar and Certificate Registrar. The Issuing
Entity shall cause to be kept at the Corporate Trust Office a Note Register in
which, subject to such reasonable regulations as it may prescribe, the Note
Registrar shall provide for the registration of Notes and of transfers and
exchanges of Notes as herein provided.

      Subject to the restrictions and limitations set forth below, upon
surrender for registration of transfer of any Note at the Corporate Trust
Office, the Issuing Entity 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.

      Subject to the foregoing, at the option of the Noteholders, Notes may be
exchanged for other Notes of like tenor and in authorized initial Note Principal
Balances evidencing the same Class and aggregate Percentage Interests upon
surrender of the Notes to be exchanged at the Corporate Trust Office of the Note
Registrar. Whenever any Notes are so surrendered for exchange, the Issuing
Entity shall execute and the Indenture Trustee 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

                                       26

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 Issuing Entity hereby appoints the Indenture Trustee as (i)
Certificate Registrar to keep at its Corporate Trust Office a Certificate
Register pursuant to Section 3.09 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 3.05 of the Trust Agreement and (ii) Note Registrar
under this Indenture. The Indenture Trustee hereby accepts such appointments.

      Section 4.04 Mutilated, Destroyed, Lost or Stolen Notes. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the Indenture Trustee such security or
indemnity as may be required by it to hold the Issuing Entity and the Indenture
Trustee harmless, then, in the absence of notice to the Issuing Entity, the Note
Registrar or the Indenture Trustee 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 Issuing Entity shall execute, and upon its request the Indenture
Trustee 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 Issuing Entity 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 Issuing Entity and the Indenture Trustee 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 Issuing Entity or the Indenture Trustee in connection
therewith.

      Upon the issuance of any replacement Note under this Section 4.04, the
Issuing Entity 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 Indenture Trustee) connected therewith.

      Every replacement Note issued pursuant to this Section 4.04 in replacement
of any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Issuing Entity, 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.

                                       27
<PAGE>

      The provisions of this Section 4.04 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 4.05 Persons Deemed Owners. Prior to due presentment for
registration of transfer of any Note, the Issuing Entity, the Indenture Trustee,
the Paying Agent and any agent of the Issuing Entity or the Indenture Trustee
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 neither the Issuing Entity,
the Indenture Trustee, the Paying Agent nor any agent of the Issuing Entity or
the Indenture Trustee shall be affected by notice to the contrary.

      Section 4.06 Cancellation. All Notes surrendered for payment, registration
of transfer, exchange or redemption shall, if surrendered to any Person other
than the Indenture Trustee, be delivered to the Indenture Trustee and shall be
promptly cancelled by the Indenture Trustee. The Issuing Entity may at any time
deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Issuing Entity may have acquired
in any manner whatsoever, and all Notes so delivered shall be promptly cancelled
by the Indenture Trustee. No Notes shall be authenticated in lieu of or in
exchange for any Notes cancelled as provided in this Section 4.06, except as
expressly permitted by this Indenture. All cancelled Notes may be held or
disposed of by the Indenture Trustee in accordance with its standard retention
or disposal policy as in effect at the time unless the Issuing Entity shall
direct by an Issuing Entity Request that they be destroyed or returned to it;
provided, however, that such Issuing Entity Request is timely and the Notes have
not been previously disposed of by the Indenture Trustee.

      Section 4.07 Book-Entry Notes. The Offered Notes, upon original issuance,
will be issued in the form of typewritten Notes to be delivered to the Indenture
Trustee as Custodian for the Depository. The Offered Notes shall initially be
registered on the Note Register in the name of Cede & Co., the nominee of the
Depository, and no Beneficial Owner will receive a Definitive Note representing
such Beneficial Owner's interest in such Note, except as provided in Section
4.09. With respect to such Notes, unless and until definitive, fully registered
Notes (the "Definitive Notes") have been issued to Beneficial Owners pursuant to
Section 4.09:

            (i) the provisions of this Section 4.07 shall be in full force and
      effect;

            (ii) the Note Registrar, the Paying Agent and the Indenture Trustee
      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 4.07
      conflict with any other provisions of this Indenture, the provisions of
      this Section 4.07 shall control;

                                       28
<PAGE>

            (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 4.09, 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 Indenture
      Trustee.

      Section 4.08 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 4.09, the Indenture Trustee 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 4.09 Definitive Notes. If (i) the Depository notifies the Issuing
Entity that it is no longer willing or able to properly discharge its
responsibilities with respect to the Offered Notes or (ii) after the occurrence
of an Event of Default, Beneficial Owners of Offered Notes representing
beneficial interests aggregating at least a majority of the Note Principal
Balances of the Offered Notes advise the Depository in writing that the
continuation of a book-entry system through the Depository is no longer in the
best interests of the Beneficial Owners, then the Depository shall notify all
Beneficial Owners and the Indenture Trustee of the occurrence of any such event
and of the availability of Definitive Notes to Beneficial Owners requesting the
same. Upon surrender to the Indenture Trustee of any such Note representing the
Book-Entry Notes by the Depository, accompanied by registration instructions,
the Issuing Entity shall execute and the Indenture Trustee shall authenticate
the Definitive Notes in accordance with the instructions of the Depository. None
of the Issuing Entity, the Note Registrar or the Indenture Trustee 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 Indenture Trustee shall recognize the Holders of the
Definitive Notes as Noteholders.

      Section 4.10 Tax Treatment. The Issuing Entity has entered into this
Indenture, and the Offered Notes and the Class M-2 and Class B Notes will be
issued with the intention that, for federal, state and local income, single
business and franchise tax purposes, the Offered Notes and the Class M-2 and
Class B Notes will qualify as indebtedness. The Issuing Entity and the Indenture
Trustee (in accordance with Section 6.07 hereof), by entering into this
Indenture, and each Noteholder, by its acceptance of its Note (and each
Beneficial Owner by its acceptance of an interest in the applicable Book-Entry
Note), agree to treat the Notes for federal, state and local income, single
business and franchise tax purposes as indebtedness. Subsequent to a TMP Trigger
Event, it is the intention that three REMIC Elections will be made with respect
to certain assets of the Trust Estate pursuant to Article XI herein.

      Section 4.11 Satisfaction and Discharge of Indenture. This Indenture shall
cease to be of further effect with respect to the Notes except as to (i) rights
of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments

      Section 4.15 Representation Regarding ERISA. By acquiring an Offered 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 the
Note with Plan Assets or (2) (A) the acquisition, holding and transfer of such
Note will not give rise to a nonexempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code and (B) the Notes are rated investment
grade or better and such person believes that the Offered Notes are properly
treated as indebtedness without substantial equity features for purposes of the
Department of Labor regulation 29 C.F.R. Section 2510.3-101, and agrees to so
treat the Offered Notes. Alternatively, regardless of the rating of the Offered
Notes, such person may provide the Indenture Trustee and the Owner Trustee with
an opinion of counsel, which opinion of counsel will not be at the expense of
the Issuing Entity, the Seller, any Underwriter, the Owner Trustee, the
Indenture Trustee, the Master Servicer or any successor servicer which opines
that the acquisition, holding and transfer of such Note or interest therein is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Issuing Entity, the Seller, the Depositor, any Underwriter, the
Owner Trustee, the Indenture Trustee, the Master Servicer or any successor
servicer to any obligation in addition to those undertaken in the Indenture or
Servicing Agreement.

      Section 4.16 Private Notes.

      No Transfer of a Private Note shall be made unless such Transfer is made
pursuant to an effective registration statement under the Securities Act and any
applicable state securities laws or is exempt from the registration requirements
under the Securities Act and such state securities laws. In the event that a
transfer is to be made in reliance upon an exemption from the Securities Act and
such state securities laws, in order to assure compliance with the Securities
Act and such state securities laws, the Noteholder desiring to effect such
Transfer and such Noteholder's prospective transferee shall each certify to the
Indenture Trustee in writing the facts surrounding the Transfer in substantially
the forms set forth in Exhibit D (the "Transferor Certificate") and (i) deliver
a letter in substantially the form of either Exhibit F (the "Investment Letter")
or Exhibit E (the "Rule 144A Letter") or (ii) there shall be delivered to the
Indenture Trustee at the expense of the Noteholder desiring to effect such
transfer an Opinion of Counsel that such Transfer may be made pursuant to an
exemption from the Securities Act. The Depositor shall provide to any Holder of
a Private Note and any prospective transferee designated by any such Holder,
information regarding the related Notes and the Mortgage Loans and such other
information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for transfer of any such Note without registration
thereof under the Securities Act pursuant to the registration exemption provided
by Rule 144A. The Indenture Trustee and the Master Servicer shall cooperate with
the Depositor in providing the Rule 144A information referenced in the preceding
sentence, including providing to the Depositor such information regarding the
Notes, the Mortgage Loans and other matters regarding the Issuing Entity as the
Depositor shall reasonably request to meet its obligation under the preceding
sentence. Each Holder of a Private Note desiring to effect such Transfer shall,
and does hereby agree to, indemnify the Indenture Trustee, the Depositor, the
Seller and the Master Servicer against any liability that may result if the
Transfer is not so exempt or is not made in accordance with such federal and
state laws. Notwithstanding the foregoing, the provisions of this paragraph
shall not apply to the initial transfer of the Private Notes to the Depositor or
the Seller.

      So long as a TMP Trigger Event has not occurred, no person shall become a
Noteholder of a Private Note, so long as any such Notes are Outstanding, until
it shall establish its status as a real estate investment trust ("REIT") or as a
"qualified REIT subsidiary" ("QRS") within the meaning of Section 856(a) or
Section 856(i) of the Code, respectively, by submitting to the Indenture Trustee
and the Owner Trustee, the Transferee Certificate set forth in Exhibit G hereto.

      So long as a TMP Trigger Event has not occurred, no offer, sale, transfer,
pledge, hypothecation or other disposition (including any pledge, sale or
transfer under a repurchase transaction or securities loan) of any Private Note
shall be made to any transferee unless, prior to such disposition, the proposed
transferor delivers to the Owner Trustee and the Indenture Trustee an Opinion of
Counsel, rendered by a law firm generally recognized to be qualified to opine
concerning the tax aspects of asset securitization, to the effect that such
transfer (including any disposition permitted following any default under any
pledge or repurchase transaction) will not cause the Trust to be no longer be
treated for federal income tax purposes as a "qualified REIT subsidiary" within
the meaning of Section 856(i) of the Code. Notwithstanding the foregoing, the
provisions of this paragraph shall not apply to the initial transfer of the
Private Notes to the Depositor or the Seller.

representing not less than a majority of the aggregate Note Principal Balance of
the Notes Offered Notes, by written notice to the Issuing Entity and the

            such acceleration had not occurred; and

                  (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;

whole amount then due and payable on the Offered Notes for principal and
interest, with interest at the applicable Note Rate upon the overdue principal,
and in addition thereto such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Indenture Trustee and its agents and

manner provided by law out of the property of the Issuing Entity or other
obligor the Offered Notes, wherever situated, the monies adjudged or decreed to
be payable.

Trustee, subject to the provisions of Section 11.16 hereof may, as more
particularly provided in Section 5.04 hereof, in its discretion, proceed to

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.

other obligor upon the Offered 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

      Section 5.04 Remedies; Priorities. (a) If an Event of Default shall have
occurred and be continuing and if an acceleration has been declared and not
rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the
provisions of Section 11.16 hereof may, and shall, at the written direction of
the Holders of a majority of the aggregate Note Principal Balances of the

            (i) institute Proceedings in its own name and as trustee of an
      express trust for the collection of all amounts then payable on the Notes
      or under this Indenture with respect thereto, whether by declaration or

      Entity and any other obligor upon such Notes monies adjudged due;

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

            (iii) exercise any remedies of a secured party under the UCC and

      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 Offered Notes, (B) the proceeds of such sale or
liquidation distributable to the Holders of the Offered Notes are sufficient to
discharge in full all amounts then due and unpaid upon such Notes for principal
and interest and amounts due and unpaid under the Swap Agreement 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 Offered Notes as they would have become due if the Offered 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 the Offered
Notes. In determining such sufficiency or insufficiency with respect to clause
(B) and (C), the Indenture Trustee may, but need not, obtain and rely upon an
opinion (obtained at the expense of the Trust) of an Independent investment
banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Trust Estate for such purpose.
Notwithstanding the foregoing, so long as an Event of Default under the
Servicing Agreement has not occurred, any Sale of the Trust Estate shall be made
subject to the continued servicing of the Mortgage Loans by the Master Servicer
as provided in the Servicing Agreement.

      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

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 Offered Notes and other obligations of the Issuing Entity and
the Indenture Trustee shall take such desire into account when determining

Estate for such purpose.

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

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

            (ii) the Holders of not less than 25% of the aggregate Note
      Principal Balances of the Offered 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

            (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 Offered 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 Offered Notes, the
Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, 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 Issuing Entity, the Indenture
Trustee and the Noteholders shall, subject to any determination in such
Proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Indenture Trustee and
the Noteholders shall continue as though no such Proceeding had been instituted.

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

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

      Section 5.11 Control By Noteholders. The Holders of a majority of the
aggregate Note Principal Balances of Offered 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 Offered 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 Note Principal Balances of the Offered Notes; and

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

payment of principal of or interest on any of the Offered 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 Issuing Entity, 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 Offered Notes or (c) any suit instituted by any
Noteholder for the enforcement of the payment of principal of or interest on any
Note on or after the respective due dates expressed in such Note and in this
Indenture.

      Section 5.14 Waiver of Stay or Extension Laws. The Issuing Entity
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 Issuing Entity (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 Section 5.05
hereof and this Section 5.15. The power to effect any such Sale shall not be
exhausted by any one or more Sales as to any portion of the Trust Estate
remaining unsold, but shall continue unimpaired until the entire Trust Estate
shall have been sold or all amounts payable on the Notes and under this
Indenture shall have been paid. The Indenture Trustee may from time to time
postpone any public Sale by public announcement made at the time and place of
such Sale. The Indenture Trustee hereby expressly waives its right to any amount
fixed by law as compensation for any Sale.

<PAGE>

      (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, the cost for which the
      Indenture Trustee shall be entitled to be reimbursed pursuant to Section
      6.07 hereof), the Holders of Notes representing at least 100% of the Note
      Principal Balances of the Offered Notes consent to such Sale.

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

      (c) Unless the Holders representing at least 66-2/3% of the Note Principal
Balances of the Offered Notes have otherwise consented or directed the Indenture
Trustee, at any public Sale of all or any portion of the Trust Estate at which a
minimum bid equal to or greater than the amount described in paragraph (2) of
subsection (b) of this Section 5.15 has not been established by the Indenture
Trustee and no Person bids an amount equal to or greater than such amount, the
Indenture Trustee, as trustee for the benefit of the Holders of the Offered
Notes, shall bid an amount at least $1.00 more than the highest other bid.

      (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 payment 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

                                       42
<PAGE>

      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 Issuing Entity 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 Issuing Entity to transfer and convey its
      interest in any portion of the Trust Estate in connection with a Sale
      thereof, and to take all action necessary to effect such Sale; and

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

      Section 5.16 Action on Notes. The Indenture Trustee's right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuing Entity 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 Issuing Entity. Any money or property collected by
the Indenture Trustee shall be applied in accordance with Section 5.04(b)
hereof.

Promptly following a request from the Indenture Trustee to do so, the Issuing

lawful action as the Indenture Trustee may request to cause the Issuing Entity
to compel or secure the performance and observance by the Seller and the Master
Servicer, as applicable, of each of their obligations to the Issuing Entity
under or in connection with the Servicing Agreement, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Issuing Entity
under or in connection with the Servicing Agreement to the extent and in the
manner directed by the Indenture Trustee, as pledgee of the Mortgage Loans,
including the transmission of notices of default on the part of the Seller or
the Master Servicer thereunder and the institution of legal or administrative
actions or proceedings to compel or secure performance by the Seller or the
Master Servicer of each of their obligations under the Sale and the Servicing
Agreement.

the direction (which direction shall be in writing or by telephone (confirmed in
writing promptly thereafter)) of the Holders of 66-2/3% of the Note Principal
Balances of the Offered Notes, shall exercise all rights, remedies, powers,
privileges and claims of the Issuing Entity against the

                                       43
<PAGE>

Seller or the Master Servicer under or in connection with the Servicing

occurred and is continuing, the Indenture Trustee shall exercise the rights and

circumstances in the conduct of such person's own affairs.

      (b) Except during the continuance of an Event of Default:

      requirements of this Indenture; however, the Indenture Trustee shall
      examine the certificates and opinions to determine whether or not they
      conform to the requirements of this Indenture.

      this Section 6.01;

            (ii) the Indenture Trustee shall not be liable for any error of

      action it takes or omits to take in good faith in accordance with a

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

                                       45
<PAGE>

believe that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

the liability of or affording protection to the Indenture Trustee shall be
subject to the provisions of this Section.

      (h) The Indenture Trustee shall act in accordance with Sections 6.03 and

faith and in accordance with the advice or opinion of such counsel.

      (f) For the limited purpose of effecting any action to be undertaken by

be responsible for any willful misconduct or negligence on the part of any

in its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Issuing Entity or its Affiliates with the same

Indenture Trustee shall promptly mail to each Noteholder notice of the Event of
Default after it is actually 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
Offered Note, the Indenture Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of Noteholders.

      Section 6.06 Reports by Indenture Trustee to Holders and Tax
Administration. The Indenture Trustee shall deliver to each Noteholder such
information as may be required to enable such holder to prepare its federal and
state income tax returns.

(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 Issuing Entity 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 and shall file such information returns
with the Internal Revenue Service with respect to payments or accruals of
interest on the Notes as are required to be filed under the Code or applicable
Treasury Regulations. All tax returns and information reports shall be signed by
the Owner Trustee as provided in Section 5.03 of the Trust Agreement. Subsequent

under Article XI.

      Section 6.07 Compensation. The Indenture Trustee shall (a) concurrently
and in accordance with Section 3.08 of the Sale and Servicing Agreement (i) on
each Payment Date, withdraw the Indenture Trustee Fee from the Payment Account
for such Payment Date and (ii) on each anniversary of the first Payment Date,
commencing in ____________, withdraw the Owner Trustee Fee from the Payment

                                       47
<PAGE>

hereof. In addition, the Indenture Trustee will each be entitled to recover from
the Payment Account pursuant to Section 3.08(a) of the Sale and Servicing
Agreement all reasonable out-of-pocket expenses, disbursements and advances and
the expenses of the Indenture Trustee in connection with any breach of this
Agreement or any claim or legal action (including any pending or threatened
claim or legal action) incurred or made by the Indenture Trustee 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 willful misfeasance, bad faith or negligence or
which is the responsibility of the Noteholders as provided herein. Such
compensation and reimbursement obligation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust.
Additionally, the Indenture Trustee and any director, officer, employee or agent
of the Indenture Trustee shall be indemnified by the Trust and held harmless
against any loss, liability or expense (including reasonable attorney's fees and
expenses) incurred in the administration of this Indenture (other than its
ordinary out of pocket expenses incurred hereunder) or in connection with any
claim or legal action relating to (a) the Basic Documents or (b) the Notes,
other than any loss, liability or expense incurred by reason of its negligence
or intentional misconduct, or which is the responsibility of the Noteholders as
provided herein. Such indemnity shall survive the termination of this Indenture
or the resignation or removal of the Indenture Trustee hereunder.

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

      Section 6.08 Replacement of Indenture Trustee. No resignation or removal
of the Indenture Trustee and no appointment of a successor Indenture Trustee
shall become effective until the acceptance of appointment by the successor
Indenture Trustee pursuant to this Section 6.08. The Indenture Trustee may
resign at any time by so notifying the Issuing Entity. Holders of a majority of
Note Principal Balances of the Offered Notes may remove the Indenture Trustee by
so notifying the Indenture Trustee and may appoint a successor Indenture
Trustee. The Issuing Entity shall, remove the Indenture Trustee if:

      (i)   the Indenture Trustee fails to comply with Section 6.11 hereof;

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

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

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

      If the Indenture Trustee resigns or is removed or if a vacancy exists in
the office of the Indenture Trustee for any reason (the Indenture Trustee in
such event being referred to herein as

                                       48
<PAGE>

the retiring Indenture Trustee), the Issuing Entity shall, promptly appoint a
successor Indenture Trustee.

      A successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee and to the Issuing Entity.
Thereupon, the resignation or removal of the retiring Indenture Trustee shall
become effective, and the successor Indenture Trustee shall have all the rights,

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

      If a successor Indenture Trustee does not take office within 60 days after
the retiring Indenture Trustee resigns or is removed, the retiring Indenture
Trustee, the Issuing Entity or the Holders of a majority of Note Principal
Balances of the Offered Notes may petition any court of competent jurisdiction

provided, that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11 hereof. The Indenture Trustee shall
provide the Rating Agencies with prior written notice of any such transaction.

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

      Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture
Trustee. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
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

trustee hereunder shall be required to meet the terms of eligibility as a

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

      (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.

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

reason the amount deposited by the Issuing Entity is not sufficient to make such
redemption or such redemption cannot be completed for any reason, the amount so
deposited by the Master Servicer with the Indenture Trustee shall be promptly
returned to the Master Servicer in full and shall not be used for any other
purpose or be deemed to be part of the Trust Estate. Subsequent to a TMP Trigger
Event and any REMIC Elections made pursuant to Article XI hereunder, the
Additional Termination Requirements in Article XII shall apply.

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

            (viii) subsequent to a TMP Trigger Event, to correct or add any
      provisions to this Indenture to comply with the REMIC Provisions or to
      prevent the imposition of any tax on any REMIC created hereunder;

      and provided, further, that such action shall not, as evidenced by an
Opinion of Counsel, cause the Issuing Entity to be subject to an entity level
tax or cause any Class of Offered Notes currently outstanding to cease to be
qualified as indebtedness.

                                       58

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

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

      Section 9.02 Supplemental Indentures With Consent of Noteholders. The
Issuing Entity and the Indenture Trustee, when authorized by an Issuing Entity
Request, also may, with prior notice to the Rating Agencies and, with the
consent of the Holders of not less than a majority of the Note Principal Balance
of each Class of Offered Notes affected thereby, by Act (as defined in Section
10.03 hereof) of such Holders delivered to the Issuing Entity and the Indenture
Trustee, enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture or of modifying in any manner the
rights of the Holders of the Notes under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Note affected thereby:

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

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

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

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

                                       59
<PAGE>

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

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

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

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

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

      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 Issuing Entity and the Indenture
Trustee of any supplemental indenture pursuant to this Section 9.02, the
Indenture Trustee shall mail to the Holders of the Notes to which such amendment
or supplemental indenture relates a notice setting forth in general terms the
substance of such supplemental indenture. Any failure of the Indenture Trustee
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 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 stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Indenture Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
that affects the Indenture Trustee'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

                                       60
<PAGE>

thereby, and the respective rights, limitations of rights, obligations, duties,
liabilities and immunities under this Indenture of the Indenture Trustee, the
Issuing Entity 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 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 Indenture Trustee shall,
bear a notation in form approved by the Indenture Trustee as to any matter
provided for in such supplemental indenture. If the Issuing Entity or the
Indenture Trustee shall so determine, new Notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuing Entity, to any such
supplemental indenture may be prepared and executed by the Issuing Entity and
authenticated and delivered by the Indenture Trustee in exchange for Outstanding
Notes.

                                   ARTICLE X

                                  MISCELLANEOUS

      Section 10.01 Compliance Certificates and Opinions, etc. (a) Upon any
application or request by the Issuing Entity to the Indenture Trustee to take
any action under any provision of this Indenture, the Issuing Entity 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
Issuing Entity 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
Issuing Entity 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 Issuing Entity is required to furnish to the
      Indenture Trustee an Officer's Certificate certifying or stating the
      opinion of any signer thereof as to the

                                       62
<PAGE>

      matters described in clause (i) above, the Issuing Entity shall also
      deliver to the Indenture Trustee an Independent Certificate from a
      nationally recognized accounting firm as to the same matters, if the fair
      value of the securities to be so deposited and of all other such
      securities made the basis of any such withdrawal or release since the
      commencement of the then current fiscal year of the Issuing Entity, 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 Offered
      Notes, but such a certificate need not be furnished with respect to any
      securities so deposited, if the fair value thereof as set forth in the
      related Officer's Certificate is less than $25,000 or less than one
      percent of the Note Principal Balances of the Offered Notes.

            (iii) Whenever any property or securities are to be released from
      the lien of this Indenture, the Issuing Entity 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 Issuing Entity 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 Issuing Entity 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 Offered Notes, but such certificate need not be furnished
      in the case of any release of property or securities if the fair value
      thereof as set forth in the related Officer's Certificate is less than
      $25,000 or less than one percent of the then Note Principal Balances of
      the Offered 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 Issuing Entity
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 Issuing Entity, stating that the information with respect to
such factual matters is in the possession of the Seller or the Issuing

                                       63
<PAGE>

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

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

      Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuing
Entity shall deliver any document as a condition of the granting of such
application, or as evidence of the Issuing Entity'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 Issuing Entity 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 Issuing Entity. 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 Issuing Entity, 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 Issuing Entity in reliance thereon, whether or not notation of
such action is made upon such Note.

      Section 10.04 Notices etc., to Indenture Trustee Issuing Entity 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:

                                       64
<PAGE>

            (i) the Indenture Trustee by any Noteholder or by the Issuing Entity
      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 Issuing Entity; or

            (ii) the Issuing Entity by the Indenture Trustee or by any
      Noteholder shall be sufficient for every purpose hereunder if in writing
      and mailed first-class, postage prepaid to the Issuing Entity addressed
      to: _____________________________, or at any other address previously
      furnished in writing to the Indenture Trustee by the Issuing Entity. The
      Issuing Entity 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 Issuing Entity,
the Indenture Trustee or the Owner Trustee shall be in writing, mailed
first-class postage pre-paid, to (i) in the case of [RATING AGENCY], at the
following address: _______________ and (ii) in the case of [RATING AGENCY, at
the following address: ___________________; 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 in writing
and mailed, first-class, postage prepaid to each Noteholder affected by such
event, at such Person's address as it appears on the Note Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given regardless of
whether such notice is in fact actually received.

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

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

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

      Section 10.06 Effect of Headings. The Article and Section headings herein
are for convenience only and shall not affect the construction hereof.

                                       65
<PAGE>

      Section 10.07 Successors and Assigns. All covenants and agreements in this
Indenture and the Notes by the Issuing Entity 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 10.08 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 10.09 [Reserved].

      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 SECTION 5-1401 OF THE GENERAL OBLIGATIONS
LAWS), 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 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 Issuing Entity 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 Issuing Entity Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuing Entity,
the Owner Trustee or the Indenture Trustee on the Notes or under this Indenture
or any certificate or other writing delivered in connection herewith or
therewith, against (i) the Indenture Trustee or the Owner Trustee in its
individual capacity, (ii) any owner of a beneficial interest in the Issuing
Entity or (iii) any partner, owner, beneficiary, agent, officer, director,
employee or agent of the Indenture Trustee or the Owner Trustee in its
individual capacity, any holder of a beneficial interest in the Issuing Entity,
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

                                       66
<PAGE>

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 Issuing Entity
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, by entering into this
Indenture, and each Noteholder, by accepting a Note, 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 Issuing Entity, or join in any
institution against the Depositor or the Issuing Entity 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.

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

            Section 11.01 Indenture Trustee to Administer REMICs.

      (a) This Article XI shall only apply subsequent to a TMP Trigger Event.

      (b) Prior to any REMIC Elections being made with respect to the Trust, the
Master Servicer shall dispose of any REO Property in a manner that maximizes the
Liquidation Proceeds. In no event shall any REO Property be included as an asset
of any REMIC.

      (c) Subsequent to a TMP Trigger Event, the Indenture Trustee shall make or
cause to be made two REMIC Elections, such REMICs to be designated as REMIC I
and REMIC II as set forth in this Indenture and the Appendix on Forms 1066 or
other appropriate federal tax or information return for the taxable year ending
on the last day of the calendar year in which the TMP Trigger Event occurs. The
regular interests and residual interest in each REMIC shall be as designated in
Section 11.04.

      (d) The Indenture Trustee shall designate the REMIC Closing Date as the

as of the "Startup Day", the following restrictions on foreclosure shall apply:
In connection with the servicing of any Mortgage Loan, the Master Servicer shall
not acquire any Mortgaged Property on behalf of any REMIC created hereunder in
connection with a default or imminent default on a Foreclosure Restricted Loan,
if acquiring title to the Mortgaged Property underlying the loan would cause the
adjusted basis, for federal income tax purposes, of these Mortgaged Properties
owned by the related REMIC after foreclosure, along with any other assets owned
by the related REMIC other than "qualified mortgages" and "permitted
investments" within the meaning of Section 860G of the Code, to exceed 0.75% of
the adjusted basis of the assets of the related REMIC. If the adjusted basis of
such Mortgaged Properties in foreclosure, along with any other assets owned by
the related REMIC, other than "qualified mortgages" and "permitted investments"
with the meaning of Section 860G of the Code, exceed 1.0% of the adjusted basis
of the assets of the related REMIC immediately after the distribution of
principal and interest on any Distribution Date, the Master Servicer will
dispose of enough of such Mortgaged Properties in foreclosure, for cash or
otherwise, so that the adjusted basis of such Mortgaged Properties in
foreclosure, along with any other assets owned by the related REMIC, other than
"qualified mortgages" and "permitted investments" within the meaning of Section
860G of the Code, will be less than 1.0% of the adjusted basis of the assets of
the related REMIC.

      (f) The Master Servicer shall pay any and all tax related expenses (not
including taxes) of each REMIC, including, but not limited to, any professional
fees or expenses related to audits or any administrative or judicial proceedings
with respect to such REMIC that involve the Internal Revenue Service or state
tax authorities, but only to the extent that (i) such expenses are ordinary or
routine expenses, including expenses of a routine audit but not expenses of
litigation (except as described in (ii)); or (ii) such expenses or liabilities
(including taxes and penalties) are

                                       68
<PAGE>

attributable to the negligence or willful misconduct of the Master Servicer in
fulfilling its duties hereunder. The Master Servicer shall be entitled to
reimbursement of expenses to the extent provided in clause (i) above from the
Collection Account.

      (g) The Indenture Trustee shall prepare or cause to be prepared, sign and
file or cause to be filed, each REMIC's federal and state tax and information
returns as such REMIC's direct representative. The expenses of preparing and
filing such returns shall be borne by the Indenture Trustee.

      (h) The Holder of the Owner Trust Certificates holding the largest
Percentage Interest shall be the "tax matters person" as defined in the REMIC
Provisions (the "Tax Matters Person") with respect to each of REMIC I and REMIC
II. The Indenture Trustee is irrevocably designated as and shall act as
attorney-in-fact and agent for each Tax Matters Person for each REMIC. The
Indenture Trustee, as agent for the Tax Matters Person, shall perform, on behalf
of each REMIC, all reporting and other tax compliance duties that are the
responsibility of such REMIC under the Code, the REMIC Provisions, or other
compliance guidance issued by the Internal Revenue Service or any state or local
taxing authority. Among its other duties, if required by the Code, the REMIC
Provisions, or other such guidance, the Indenture Trustee, as agent for the Tax
Matters Person, shall provide (i) to the Treasury or other governmental
authority such information as is necessary for the application of any tax
relating to the transfer of an Class R Certificate to any disqualified person or
organization and (ii) to the Noteholders such information or reports as are
required by the Code or REMIC Provisions.

      (i) The Indenture Trustee, the Master Servicer, and the Holders of Notes
shall take any action or cause any REMIC to take any action necessary to create
or maintain the status of such REMIC as a REMIC under the REMIC Provisions and
shall assist each other as necessary to create or maintain such status. Neither
the Indenture Trustee, the Master Servicer, nor the Holder of any Owner Trust
Certificate shall take any action or cause any REMIC to take any action or fail
to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon
such REMIC (including, but not limited to, the tax on prohibited transactions as
defined in Code Section 860F(a)(2) and the tax on prohibited contributions set
forth on Section 860G(d) of the Code) (either such event, an "Adverse REMIC
Event") unless the Indenture Trustee and the Master Servicer have received an
Opinion of Counsel (at the expense of the party seeking to take such action) to
the effect that the contemplated action will not endanger such status or result
in the imposition of such a tax. In addition, prior to taking any action with
respect to any REMIC or the assets therein, or causing such REMIC to take any
action, which is not expressly permitted under the terms of this Agreement, any
Holder of the Owner Trust Certificates will consult with the Indenture Trustee
and the Master Servicer, or their respective designees, in writing, with respect
to whether such action could cause an Adverse REMIC Event to occur with respect
to such REMIC, and no such Person shall take any such action or cause such REMIC
to take any such action as to which the Indenture Trustee or the Master Servicer
has advised it in writing that an Adverse REMIC Event could occur.

      (j) The Holder of the Owner Trust Certificates shall pay when due its pro
rata share of any and all taxes imposed on any REMIC by federal or state
governmental authorities. To the

                                       69
<PAGE>

extent that such REMIC taxes are not paid by the holder of the Owner Trust
Certificates, the Indenture Trustee shall pay any remaining REMIC taxes out of
current or future amounts otherwise payable to the Holder of the Owner Trust
Certificates or, if no such amounts are available, out of other amounts held in
the Collection Account, and shall reduce amounts otherwise payable to Holders of
the REMIC Regular Interests or the Notes, as the case may be.

      (k) The Indenture Trustee, shall, for federal income tax purposes,
maintain or cause to be maintained books and records with respect to each REMIC
on a calendar year and on an accrual basis.

      (l) No additional contributions of assets shall be made to any REMIC,
except as expressly provided in the Sale and Servicing Agreement with respect to
Replacement Mortgage Loans.

      (m) Neither the Indenture Trustee nor the Master Servicer shall enter into
any arrangement by which any REMIC will receive a fee or other compensation for
services.

      (n) On or before April 15th of each calendar year beginning in the year
after any REMIC Elections are made, the Master Servicer shall deliver to the
Indenture Trustee and each Rating Agency an Officer's Certificate stating the
Master Servicer's compliance with the provisions of this Section 11.01.

      Section 11.02 Carryover Reserve Fund.

      (a) On the REMIC Closing Date, the Indenture Trustee shall establish and
maintain in its name, in trust for the benefit of the Holders of the Notes, the
Carryover Reserve Fund. The Carryover Reserve Fund shall have five sub-accounts,
beneficially owned by the Holders of the Class IO-1 Notes, Class IO-2 Notes,
Class IO-3 notes, Class IO-4 Notes and Class IO-5 Notes, respectively. On the
REMIC Closing Date, the Depositor will deposit, or cause to be deposited, into
the Carryover Reserve Fund $5,000. On each Distribution Date as to which there
is Net Rate Carryover payable to the Class A or Class M-1 Notes, the Indenture
Trustee shall deposit the amounts pursuant to paragraphs [____] of Section 4.02
into the Carryover Reserve Fund and the Indenture Trustee has been directed by
the Class IO Noteholders to distribute such amounts to the Holders of the Class
A and Class M-1 Notes in the amounts and priorities set forth in clause [___]of
Section [___]. For federal income tax purposes, such amounts shall be deemed
paid to the Holders of the Class IO Notes and from the Class IO Notes to the
Carryover Reserve Fund.

      (b) The Carryover Reserve Fund shall be an Eligible Account, and funds on
deposit therein shall be held separate and apart from, and shall not be
commingled with, any other moneys, including without limitation, other moneys
held by the Indenture Trustee pursuant to this Indenture.

      (c) Funds in the Carryover Reserve Fund may be invested in Permitted
Investments. Any earnings on such amounts shall be payable to the Class IO-1
Notes, Class IO-2 Notes, Class IO-3 notes, Class IO-4 Notes and Class IO-5
Notes. The Class IO-1 Notes, Class IO-2 Notes, Class IO-3 notes, Class IO-4
Notes and Class IO-5 Notes shall evidence ownership of the related sub-accounts
of the Carryover Reserve Fund for federal tax purposes and the

                                       70
<PAGE>

Holders thereof evidencing not less than 50% of the Voting Rights of such
Classes, in the aggregate, shall direct the Trustee in writing as to the
investment of amounts therein. In the absence of such written direction, all
funds in the Carryover Reserve Fund shall be invested by the Trustee in [___].

      (d) Upon termination of the Trust, any amounts remaining in the Carryover
Reserve Fund shall be distributed to the Holders of the Class IO Notes [divided
how?]

      (e) The Indenture Trustee shall treat the Carryover Reserve Fund as an
outside reserve fund within the meaning of Treasury Regulation Section
1.860G-2(h) that is owned by the Holders of the Class IO Notes and that is not
an asset of any REMIC. The Indenture Trustee shall treat the rights of the Class
A and Class M-1 Notes to receive payments from the Carryover Reserve Fund in
respect of Net Rate Carryover as a right in interest rate cap contracts written
by the Holders of the Class IO Notes, in favor of the Notes (other than the
Class IO Notes), and the Indenture Trustee shall account for such as property
held separate and apart from the regular interests it holds in the REMICs
created hereunder. This provision is intended to satisfy the requirements of
Treasury Regulation Section 1.860G-2(i) for the treatment of property rights
coupled with regular interests to be separately respected and shall be
interpreted consistent with such regulation.

      Section 11.03 Prohibited Transactions and Activities.

      Neither the Seller, the Depositor, the Master Servicer nor the Indenture
Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans,
except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii)
the bankruptcy of the Trust Estate, (iii) the termination of any REMIC pursuant
to Section [11.??] of this Agreement, (iv) a substitution pursuant to the Sale
and Servicing Agreement or (v) a repurchase of Mortgage Loans pursuant to the
Sale and Servicing Agreement, nor acquire any assets for any REMIC, nor sell or
dispose of any investments in the Payment Account for gain, nor accept any
contributions to any REMIC after the Startup Date, unless it has received an
Opinion of Counsel (at the expense of the party causing such sale, disposition,
or substitution) that such disposition, acquisition, substitution, or acceptance
will not (a) affect adversely the status of any REMIC as a REMIC or of the
interests therein other than the Owner Trust Certificates as the regular
interests therein, (b) affect the payment of interest or principal on the Notes,
(c) result in the encumbrance of the assets transferred or assigned to the Trust
Estate (except pursuant to the provisions of this Agreement) or (d) cause such
REMIC to be subject to a tax on prohibited transactions or prohibited
contributions pursuant to the REMIC Provisions.

      Section 11.04 Indemnification with Respect to Certain Taxes and Loss of
REMIC Status.

      In the event that any REMIC formed hereunder fails to qualify as a REMIC,
loses its status as a REMIC, or incurs federal, state or local taxes as a result
of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Master Servicer of its duties
and obligations set forth herein, the Master Servicer shall indemnify the Holder
of the Owner Trust Certificates against any and all losses, claims, damages,
liabilities or expenses ("Losses") resulting from such negligence; provided,
however, that the Master Servicer shall not be liable for any such Losses
attributable to the action or inaction of the

                                       71
<PAGE>

Indenture Trustee, the Depositor or the Holder of such Owner Trust Certificate,
as applicable, nor for any such Losses resulting from misinformation provided by
the Holder of such Owner Trust Certificate on which the Master Servicer has
relied. The foregoing shall not be deemed to limit or restrict the rights and
remedies of the Holder of such Owner Trust Certificate now or hereafter existing
at law or in equity. Notwithstanding the foregoing, however, in no event shall
the Master Servicer have any liability (1) for any action or omission that is
taken in accordance with and in compliance with the express terms of, or which
is expressly permitted by the terms of, this Agreement, (2) for any Losses other
than arising out of a negligent performance by the Master Servicer of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Noteholders (in addition to payment of principal and interest on the
Notes).

                                     REMIC I

      As provided herein, subsequent to a TMP Trigger Event, the Indenture
Trustee will make an election to treat the segregated pool of assets consisting
of the Mortgage Loans and certain other related assets (excluding the Carryover
Reserve Fund and any REO Property) subject to this Agreement as a real estate
mortgage investment conduit (a "REMIC") for federal income tax purposes, and
such segregated pool of assets will be designated as "REMIC I." The Class R-I
Interest will represent the sole class of "residual interests" in REMIC I for
purposes of the REMIC Provisions (as defined herein) under federal income tax
law. The following table irrevocably sets forth the designation, remittance rate
(the "Uncertificated REMIC I Pass-Through Rate") and initial Uncertificated
Principal Balance for each of the "regular interests" in REMIC I (the "REMIC I
Regular Interests"). The "latest possible maturity date" (determined for
purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii)) for each
REMIC I Regular Interest shall be the 360th distribution date. None of the REMIC
I Regular Interests will be certificated.

                         REMIC TERMINATION REQUIREMENTS

      In the event the Majority Holder of the Owner Trust Certificates exercises
the Optional Redemption of the Notes pursuant to Section 8.07 hereunder and
REMIC Elections have been made pursuant to Article XI hereunder, the Trust shall
be terminated in accordance with the following additional requirements, unless
the Indenture Trustee has been supplied with an Opinion of Counsel, at the
expense of the Majority Holder of the Owner Trust Certificates, to the effect
that the failure of the Trust to comply with the requirements of this Section
12.01 will not (i) result in the imposition of taxes on "prohibited
transactions" of a REMIC, or (ii) cause any REMIC created hereunder to fail to
qualify as a REMIC at any time that any Notes are outstanding:

      (1) The Majority Holder of the Owner Trust Certificates shall establish a
90 day liquidation period and notify the Indenture Trustee thereof, which shall
in turn specify the first day of such period in a statement attached to the
Trust's final Tax Return pursuant to Treasury Regulation Section 1.860F 1. The
Majority Holder of the Owner Trust Certificates shall prepare or cause to be
prepared a plan of complete liquidation and shall otherwise satisfy all the
requirements of a qualified liquidation under Section 860F of the Code and any
regulations thereunder;

      (2) During such 90 day liquidation period, and at or prior to the time of
making the final payment on the Notes, the Master Servicer as agent of the
Indenture Trustee shall sell all of the assets of the Trust for cash; and

      (3) After making the final payment on the Notes, the Indenture Trustee
shall distribute or credit, or cause to be distributed or credited, to the
Holder of the Owner Trust Certificates all cash on hand (other than cash
retained to meet claims) related to such Certificates, and the Trust shall
terminate at that time.

      By their acceptance of the Notes, the Holders thereof hereby authorize the
Majority Holder of the Owner Trust Certificates to specify the 90 day
liquidation period for the Trust, which authorization shall be binding upon all
successor Noteholders.

      The Indenture Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Majority Holder of the Owner Trust Certificates, and agrees to
take such other action in connection therewith as may be reasonably requested by
the Majority Holder of the Owner Trust Certificates.

             Re: Proposed Transfer of [Class __] Notes] [TRUST NAME]

Gentlemen:

      This certification is being made by ____________________ (the
"Transferor") in connection with the proposed Transfer to _____________________
(the "Transferee") of the [Class [__] Notes] (the "Notes") issued pursuant to
the Indenture, dated _________, being referred to herein as the "Indenture")
between [ISSUING ENTITY], as issuing entity, and [INDENTURE TRUSTEE] 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
of any Note, any interest in any Note or any other similar security from any
person in any manner, (c) has otherwise approached or negotiated with respect to
any Note, any interest in any Note or any other similar security with any person
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
under the Securities Act of 1933 (the "Act"), that would render the disposition
of any Note a violation of Section 5 of the Act or any state securities law, or
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

     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 4.03 of the Indenture (the "Indenture"),
dated as of ________, between [ISSUING ENTITY], as Issuing Entity, and
[INDENTURE TRUSTEE], 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.

                                       E-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, the Master Servicer or the 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, the 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, the
Servicer and the Depositor, to the effect that the purchase and holding of the
Rule 144A Securities by, on behalf of or with "plan assets" of any Plan is
permissible under applicable law, would not constitute or result in a prohibited
transaction under ERISA or Section 4975 of the Code, and would not subject the
Depositor, the Owner Trustee, the Indenture Trustee, the Certificate Registrar,
the Seller or the Master Servicer to any obligation or liability (including
liabilities under ERISA or Section 4975 of the Code) in addition to those
undertaken in the Agreement, which Opinion of Counsel shall not be

an expense of the Depositor, the Owner Trustee, the Indenture Trustee, the
Certificate Registrar, the Seller or the Master Servicer.

         This Amended and Restated Trust Agreement, dated as of __________ (as
amended from time to time, this "Trust Agreement"), among Merrill Lynch Mortgage
Investors, Inc., as depositor (the "Depositor"), [OWNER TRUSTEE], as owner
trustee (the "Owner Trustee"), and [CERTIFICATE REGISTRAR/CERTIFICATE PAYING
AGENT], as certificate registrar (in such capacity, the "Certificate Registrar")
and certificate paying agent (in such capacity, the "Certificate Paying Agent").

                                WITNESSETH THAT:

         In consideration of the mutual agreements herein contained, the
Depositor and the Owner Trustee agree as follows:

         WHEREAS, the Depositor and the Owner Trustee have previously entered
into the Trust Agreement dated __________ (the "Shortform Trust Agreement").

         WHEREAS, the parties hereto desire to amend the terms of and restate
the Trust Agreement.

         WHEREAS, the conveyance of the Mortgage Loans by the Depositor (on
behalf of the Seller) to the Trust hereunder is intended to facilitate the
simultaneous issuance of the Notes under the Indenture and issuance of the
Certificates hereunder to the Seller as Holder, and the Depositor (on behalf of
the Seller) has no present intention of selling any of the Certificates.
Accordingly, at the time of the transaction set forth herein, the Seller will
retain without interruption, through the ownership of the Certificates, the
economic benefits associated with ownership of the Mortgage Loans as well as the
economic burdens associated with such ownership, subject to the lien of the
Indenture and subject to this Agreement.

         WHEREAS, the Depositor's sole purpose hereunder is to transfer the
Mortgage Loans purchased pursuant to the Sale and Servicing Agreement, dated as
of ___________, by and among the Depositor, the Issuing Entity, the Seller, the
Master Servicer and the Indenture Trustee, to [ISSUING ENTITY] for issuance of
the [TRUST NAME], Asset-Backed Notes and Certificates, Series [________].

         In consideration of the mutual agreements herein contained, the
Depositor, the Owner Trustee and the [CERTIFICATE REGISTRAR/CERTIFICATE PAYING
AGENT], in its capacity as certificate registrar and certificate paying agent,
agree as follows:

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

            (v) if directed by holders of Certificates representing more than

      subsequent to the discharge of the Indenture, all for the benefit of the
      holders of the Certificates;

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

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

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

the Owner Trustee as trustee of the Trust effective as of the date hereof, to
have all the rights, powers and duties set forth herein.

                                       3
<PAGE>
      Section 2.05. Initial Capital Contribution of Trust Estate. The Depositor
hereby sells, assigns, transfers, conveys and sets over to the Trust, as of the
date hereof, the sum of $1. The Owner Trustee hereby acknowledges receipt in
trust from the Depositor, as of the date hereof, of the foregoing contribution,
which shall constitute the initial corpus of the Trust and shall be deposited in
the Certificate Distribution Account. The Depositor hereby sells, assigns,
transfers, conveys and sets over to the Trust, as of the date hereof, without
recourse, all right, title and interest in the Initial Mortgage Loans sold to
the Depositor pursuant to the Sale and Servicing Agreement and the Subsequent
Mortgage Loans sold to the Depositor pursuant to the Subsequent Transfer
Agreement and all rights, title and interest in the Sale and Servicing Agreement

and warranties made by the Seller under the Sale and Servicing Agreement and the
Subsequent Transfer Agreement which shall constitute the Trust Estate.

      Section 2.06. Declaration of Trust. The Owner Trustee hereby declares that
it shall hold the Owner Trust Estate in trust upon and subject to the conditions
set forth herein for the use and benefit of the Certificateholders, subject to
the obligations of the Trust under the Basic Documents. It is the intention of
the parties hereto that the Trust constitute a "statutory trust" under the
Statutory Trust Statute and that this Trust Agreement constitute the governing
instrument of such statutory trust. It is the intention of the parties hereto
that, for federal and state income and state and local franchise tax purposes,
the Trust (A) shall, as of the Closing Date and for so long as any Notes are
outstanding be treated for federal income tax purposes as a qualified REIT
subsidiary within the meaning of Section 856(i) of the Code, and thereafter be
disregarded as a separate entity (and if at any other time the Trust
Certificates are held by more than one person for federal income tax purposes,
shall be treated as a partnership), and (B) that each Class of Offered Notes
shall be debt, and the provisions of this Agreement shall be interpreted to
further this intention. Except as otherwise provided in this Trust Agreement,
the rights of the Certificateholder will be those of equity owners of the Trust.
Effective as of the date hereof, the Owner Trustee shall have all rights, powers
and duties set forth herein and in the Statutory Trust Statute with respect to
accomplishing the purposes of the Trust.

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

                                       4
<PAGE>
      Section 2.08. Title to Trust Property. Except with respect to the Mortgage
Loans, which will be assigned of record to the Indenture Trustee pursuant to the
Indenture, legal title to the Trust Estate shall be vested at all times in the
Trust as a separate legal entity except where applicable law in any jurisdiction
requires title to any part of the Trust Estate to be vested in a trustee or
trustees, in which case title shall be deemed to be vested in the Owner Trustee,
a co-trustee and/or a separate trustee, as the case may be.

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

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

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

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

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

                                       5

      agency or other governmental instrumentality having jurisdiction over the
      Depositor or its properties.

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

      Section 2.11. Payment of Trust Fees. The Owner Trustee shall receive as
compensation for its services hereunder such fees as have been separately agreed
upon before the date hereof, and the Owner Trustee shall be reimbursed by the
Depositor or the Master Servicer for its reasonable expenses hereunder and under
the Basic Documents, including the reasonable compensation, expenses and
disbursements of such agents, representatives, experts and counsel as the Owner
Trustee may reasonably employ in connection with the exercise and performance of
its rights and its duties hereunder and under the Basic Documents. The amount of
the Owner Trustee's Fee shall be paid as provided in Section 6.07 of the
Indenture.

      Section 2.12. Investment Company. Neither the Depositor nor any Holder of
a Certificate shall take any action which would cause the Trust to become an
"investment company" which would be required to register under the Investment
Company Act.

      Section 2.13. Transfer of Trust Estate to Owner Trustee. (a) Effective as
of the date hereof, the Depositor assigns, transfers, and otherwise conveys to,
and deposits with, the Trust, until this Agreement terminates pursuant to
Section 8.01, the entire Trust Estate, such conveyance to be made in exchange
for the Notes and the Certificates. Such assignment includes, without
limitation, all amounts payable to and all rights of the holder of the
Collateral pursuant to this Agreement.

      The conveyance of the Collateral and all other assets constituting the
Trust Estate by the Depositor as contemplated hereby is absolute and is intended
by the parties to constitute a sale of the Collateral and all other assets
constituting the Trust Estate by the Depositor to the Trust. It is, further, not
intended that such conveyance be deemed a pledge of security for a loan. If such
conveyance is deemed to be a pledge of security for a loan, however, the
Depositor intends that the rights and obligations of the parties to such loan
shall be established pursuant to the terms of this Agreement. The Depositor also
intends and agrees that, in such event:

            (i) this Agreement shall constitute a security agreement under
      applicable law and shall be deemed to create valid and continuing security
      interest (as defined in the applicable UCC) in the Trust Estate
      (including, without limitation, the Collateral, the Certificate
      Distribution Account and any proceeds thereof) in favor of the Trust,
      which security interest is prior to all other Liens, and is enforceable as
      such as against creditors of and purchasers from the Depositor;

            (ii) other than the security interest granted to the Trust pursuant
      to this Agreement, Depositor has not pledged, assigned, sold, granted a
      security interest in, or otherwise conveyed any of the Trust Estate, has
      not authorized the filing of and is not aware of any financing statements
      against the Trust Estate that includes a description of collateral
      covering the Trust Estate other than any financing statements relating to
      the

                                       6
<PAGE>
      security interest granted to the Trust hereunder or that has been
      terminated. The Depositor is not aware of any judgment or tax lien filings
      against Depositor;

            (iii) the Depositor owns and has good and marketable title to the
      Trust Estate free and clear of any Lien, claim or encumbrance of any
      Person;

            (iv) the Certificate Distribution Account constitutes a "deposit
      account" within the meaning of the applicable UCC. The Depositor has
      directed the Certificate Paying Agent to become the account holder of the
      Certificate Distribution Account. The Certificate Distribution Account is
      not in the name of any Person other than as provided in Section 3.10 of
      this Agreement. The Depositor has not consented to the maintenance of the
      Certificate Distribution Account in compliance with instructions of any
      Person other than the Certificate Paying Agent;

            (v) the Trust Estate (excluding the Mortgage Loans, REO Property,
      the Certificate Distribution Account and any proceeds thereof) constitutes
      "general intangibles" within the meaning of the applicable UCC). The
      Depositor has received all required consents and approvals to the pledge
      of the portions of the Trust Estate (excluding the Certificate
      Distribution Account and any proceeds thereof) constituting payment
      intangibles;

            (vi) the Depositor has caused or will have caused, within ten days,
      the filing of all appropriate financing statements in the appropriate
      filing offices under applicable law in order to perfect the security
      interest in the Trust Estate granted to the Trust hereunder. All financing
      statements filed or to be filed against the Depositor in favor of the
      Trust (or any subsequent assignee, including, without limitation, the
      Indenture Trustee) in connection herewith describing the Trust Estate
      contain a statement to the following effect, "A purchase of, or security
      interest in, any collateral described in this financing statement will
      violate the rights of the secured party;" and

            (vii) the Depositor shall, to the extent consistent with this
      Agreement, take such additional reasonable actions as may be necessary to
      ensure that, if this Agreement were deemed to create a security interest
      in the Mortgage Loans and the other assets of the Trust Estate, such
      security interest would be a perfected security interest of first priority
      under applicable law and will be maintained as such throughout the life of
      this Agreement. Notifications to, and acknowledgments, receipts or
      confirmations from, Persons holding such property, shall be deemed to be
      notifications to, or acknowledgments, receipts or confirmations from,
      financial intermediaries, bailees or agents (as applicable) of the Owner
      Trustee on behalf of the Trust (or any subsequent assignee, including,
      without limitation, the Indenture Trustee) for the purpose of perfecting
      such security interest under applicable law.

      (b) The Owner Trustee hereby acknowledges the receipt by it of the Trust
Estate and such other documents and instruments referenced above, and declares
that it holds and will hold the Trust Estate and such documents and instruments
and that it holds and will hold all other assets and documents to be included in
the Trust Estate, in trust for the exclusive use and benefit of all present and
future Certificateholders.

      (c) Except as expressly provided in Section 8.01, neither the Depositor
nor any Certificateholder shall be able to revoke the Trust established
hereunder. Except as provided in Sections 4.01, 4.02, 4.03, 5.01 and 8.01
hereof, the Owner Trustee or Certificate Paying Agent (as applicable) shall not
assign, sell, dispose of or transfer any interest in, nor may the Depositor or
any Certificateholder withdraw from the Trust, the Collateral or other asset
constituting the Trust Estate.

                 Conveyance of the Mortgage Loans; Certificates

      Section 3.01. Conveyance of the Mortgage Loans. The Depositor,
concurrently with the execution and delivery hereof, contributes, transfers,
conveys and assigns to the Trust, on behalf of the Holders of the Notes and the
Certificates, without recourse, all its right, title and interest in and to the
Initial Mortgage Loans as of the Closing Date, including all interest and
principal received on or with respect to the Initial Mortgage Loans after the
Cut-off Date (other than payments of principal and interest due on the Initial
Mortgage Loans on or before the Cut-off Date) and the Subsequent Mortgage Loans
as of the Subsequent Transfer Date, including all interest and principal
received on or with respect to the Subsequent Mortgage Loans after the
Subsequent Cut-off Date (other than payments of principal and interest due on
the Initial Mortgage Loans on or before the Subsequent Cut-off Date). The
Depositor hereby assigns to the Trust all of its right, title and interest in
the Pre-Funding Account. In addition, the Depositor hereby assigns to the Trust
all of its right, title, and interest in, to and under the Sale and Servicing
Agreement and the Subsequent Transfer Agreement.

      The conveyance of the Mortgage Loans by the Depositor (on behalf of the
Seller) to the Trust under this Agreement is intended to facilitate the
simultaneous issuance of the Notes under the Indenture and issuance of the
Certificates hereunder to the Seller as Holder, and the Depositor has no present
intention of selling any of the Certificates.

      Section 3.02. Initial Ownership. Upon the formation of the Trust by the
contribution by the Depositor pursuant to Section 2.05, and until the conveyance
of the Initial Mortgage Loans and Subsequent Mortgage Loans (as of the
Subsequent Transfer Date) pursuant to Section 3.01 and the issuance of the
Certificates, and thereafter except as otherwise permitted hereunder, the Seller
shall be the sole Certificateholder.

      Section 3.03. The Certificates. The Trust Certificates shall be issued in
the form of one or more Trust Certificates, each representing not less than a
10% Certificate Percentage Interest. The Trust Certificates shall initially be
registered in the name of _____________________. The Certificates shall be
executed on behalf of the Trust by manual or facsimile signature of an
authorized officer of the Owner Trustee and authenticated in the manner provided
in Section 3.04. The Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures shall have been affixed,
authorized to sign on behalf of the Trust, shall be validly issued and entitled
to the benefit of this Trust Agreement, notwithstanding that such individuals or
any of them shall have ceased to be so authorized prior to the authentication
and delivery of such Certificates or did not hold such offices at the date of
authentication and delivery of such Certificates. A Person shall become a
Certificateholder and shall be entitled to the rights and subject to the
obligations of a Certificateholder hereunder upon such Person's acceptance of a
Certificate duly registered in such Person's name, pursuant to Section 3.05.

      A transferee of a Certificate shall become a Certificateholder and shall
be entitled to the rights and subject to the obligations of a Certificateholder
hereunder upon such transferee's

                                       9
<PAGE>
acceptance of a Certificate duly registered in such transferee's name pursuant
to and upon satisfaction of the conditions set forth in Section 3.05.

      Section 3.04. Authentication of Certificates. The Owner Trustee shall
cause all Certificates issued hereunder to be executed and authenticated on
behalf of the Trust, authenticated and delivered to or upon the written order of
the Depositor, signed by its chairman of the board, its president or any vice
president, without further corporate action by the Depositor, in authorized
denominations. No Certificate shall entitle its holder to any benefit under this
Trust Agreement or be valid for any purpose unless there shall appear on such
Certificate a certificate of authentication substantially in the form set forth
in Exhibit A, executed by the Owner Trustee or the Certificate Registrar by
manual signature; such authentication shall constitute conclusive evidence that
such Certificate shall have been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

      Section 3.05. Registration of and Limitations on Transfer and Exchange of
Certificates. (a) The Certificate Registrar shall keep or cause to be kept, a
Certificate Register in which, subject to such reasonable regulations as it may
prescribe, the Certificate Registrar shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
[CERTIFICATE REGISTRAR] shall be the initial Certificate Registrar. If the
Certificate Registrar resigns or is removed, the Owner Trustee shall appoint a
successor Certificate Registrar.

      Subject to satisfaction of the conditions set forth below with respect to
the Certificate, upon surrender for registration of transfer of any Certificate
at the office or agency maintained pursuant to Section 3.09, the Owner Trustee
or the Certificate Registrar shall execute, authenticate and deliver in the name
of the designated transferee or transferees, one or more new Certificates in
authorized denominations of a like aggregate amount dated the date of
authentication by the Owner Trustee or the Certificate Registrar. At the option
of a Holder, the Certificates may be exchanged for other Certificates of
authorized denominations of a like aggregate amount upon surrender of the
Certificates to be exchanged at the office or agency maintained pursuant to
Section 3.09.

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

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

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

                                       10
<PAGE>
      No transfer, sale, pledge or other disposition of a Certificate shall be
made unless such transfer, sale, pledge or other disposition is exempt from the
registration requirements of the Securities Act and any applicable state
securities laws or is made in accordance with said Act and laws. In the event of
any such transfer, the Certificate Registrar or the Depositor shall prior to
such transfer require the transferee to execute (A) either (i) (a) an investment
letter in substantially the form attached hereto as Exhibit C (or in such form
and substance reasonably satisfactory to the Certificate Registrar and the
Depositor) which investment letter shall not be an expense of the Trust, the
Owner Trustee, the Certificate Registrar, the Master Servicers or the Depositor
and which investment letter states that, among other things, such transferee (1)
is a "qualified institutional buyer" as defined under Rule 144A, acting for its
own account or the accounts of other "qualified institutional buyers" as defined
under Rule 144A, and (2) is aware that the proposed transferor intends to rely
on the exemption from registration requirements under the Securities Act of
1933, as amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel
acceptable to and in form and substance satisfactory to the Certificate
Registrar and the Depositor that such transfer may be made pursuant to an
exemption, describing the applicable exemption and the basis therefor, from said
Act and laws or is being made pursuant to said Act and laws, which Opinion of
Counsel shall not be an expense of the Trust, the Owner Trustee, the Certificate
Registrar, the Master Servicer or the Depositor and (b) the transferee executes
a representation letter, substantially in the form of Exhibit F to the
Agreement, and the transferor executes a representation letter, substantially in
the form of Exhibit E hereto, each acceptable to and in form and substance
satisfactory to the Certificate Registrar and the Depositor, certifying the
facts surrounding such transfer, which representation letters shall not be an
expense of the Trust, the Owner Trustee, the Certificate Registrar, the Master
Servicer or the Depositor and (B) the Certificate of Non-Foreign Status (in
substantially the form attached hereto as Exhibit D) acceptable to and in form
and substance reasonably satisfactory to the Certificate Registrar and the
Depositor, which certificate shall not be an expense of the Trust, the Owner
Trustee, the Certificate Registrar or the Depositor; provided, however that no
certification or Opinion of Counsel will be required in connection with the
initial transfer of any such Certificate by the Depositor to an affiliate of the
Depositor. The Holder of a Certificate desiring to effect such transfer shall,
and does hereby agree to, indemnify the Trust, the Owner Trustee, the
Certificate Registrar, the Master Servicer and the Depositor against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws. Notwithstanding the foregoing, the
provisions of this paragraph shall not apply to the initial transfer of the
Certificates to the Depositor or the Seller, or an affiliate of the Seller.

      No transfer of Certificates or any interest therein shall be made to any
Person unless the Depositor, the Owner Trustee, the Certificate Registrar and
the Master Servicer are provided with an Opinion of Counsel which establishes to
the satisfaction of the Depositor, the Owner Trustee, the Certificate Registrar
and the Master Servicer that the purchase of Certificates is permissible under
applicable law, will not constitute or result in any non-exempt prohibited
transaction under ERISA or Section 4975 of the Code and will not subject the
Depositor, the Owner Trustee, the Certificate Registrar or the Master Servicer
to any obligation or liability (including obligations or liabilities under ERISA
or Section 4975 of the Code) in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Depositor, the Owner
Trustee, the Certificate Registrar or the Master Servicer. In lieu of such

                                       11
<PAGE>
Opinion of Counsel, a Person acquiring such Certificates may provide a
certification in the form of Exhibit G to this Agreement, which the Depositor,
the Owner Trustee, the Certificate Registrar and the Master Servicer may rely
upon without further inquiry or investigation. Neither an Opinion of Counsel nor
a certification will be required in connection with the initial transfer of any
such Certificate by the Depositor to an affiliate of the Depositor (in which
case, the Depositor or any affiliate thereof shall 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 and the Certificate Registrar shall be entitled to
conclusively rely upon a representation (which, upon the request of the Owner
Trustee or the Certificate Registrar, shall be a written representation) from
the Depositor of the status of such transferee as an affiliate of the Depositor.
Notwithstanding the foregoing, the provisions of this paragraph shall not apply
to the initial transfer of the Certificates to the Depositor or the Seller, or
an affiliate of the Seller.

      No person shall become a Certificateholder, so long as any Notes are
Outstanding, until it shall establish its status as a real estate investment
trust ("REIT") or as a "qualified REIT subsidiary" ("QRS") within the meaning of
Section 856(a) or Section 856(i) of the Code, respectively, by submitting to the
Certificate Registrar and the Owner Trustee, the Transferee Certificate set
forth in Exhibit H hereto.

      No offer, sale, transfer, pledge, hypothecation or other disposition
(including any pledge, sale or transfer under a repurchase transaction or
securities loan) of any Certificate shall be made to any transferee unless,
prior to such disposition, the proposed transferor delivers to the Owner Trustee
and the Certificate Registrar an Opinion of Counsel, rendered by a law firm
generally recognized to be qualified to opine concerning the tax aspects of
asset securitization, to the effect that such transfer (including any
disposition permitted following any default under any pledge or repurchase
transaction) will not cause the Trust to be no longer be treated for federal
income tax purposes as a "qualified REIT subsidiary" within the meaning of
Section 856(i) of the Code. Notwithstanding the foregoing, the provisions of
this paragraph shall not apply to the initial transfer of the Certificates to
the Depositor or the Seller, or an affiliate of the Seller.

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

      Section 3.06. Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated Certificate shall be surrendered to the Certificate Registrar, or
if the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Certificate Registrar and the Owner Trustee such security or indemnity as
may be required by them to save each of them harmless, then in the absence of
notice to the Certificate Registrar or the Owner Trustee that such Certificate
has been acquired by a bona fide purchaser, the Owner Trustee shall execute on
behalf of the Trust and the Owner Trustee or the Certificate Registrar, shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like tenor and
denomination. In connection with the issuance of any new Certificate under this
Section 3.06, the Owner Trustee or the Certificate Registrar may require the
payment of a sum sufficient to cover any expenses of the Owner Trustee or the
Certificate Registrar (including fees and expenses of counsel) and any tax or
other governmental charge that may be imposed in connection therewith.

                                       12
<PAGE>
Any duplicate Certificate issued pursuant to this Section 3.06 shall constitute
conclusive evidence of ownership in the Trust, as if originally issued, whether
or not the lost, stolen or destroyed Certificate shall be found at any time.

      Section 3.07. Persons Deemed Certificateholders. Prior to due presentation
of a Certificate for registration of transfer, the Owner Trustee, the
Certificate Registrar or any Certificate Paying Agent may treat the Person in
whose name any Certificate is registered in the Certificate Register as the
owner of such Certificate for the purpose of receiving distributions pursuant to
Section 5.02 and for all other purposes whatsoever, and none of the Trust, the
Owner Trustee, the Certificate Registrar or any Certificate Paying Agent shall
be bound by any notice to the contrary.

      Section 3.08. Access to List of Certificateholders' Names and Addresses.
The Certificate Registrar shall furnish or cause to be furnished to the
Depositor, the Certificate Paying Agent or the Owner Trustee, within 15 days
after receipt by the Certificate Registrar of a written request therefor from
the Depositor, the Certificate Paying Agent or the Owner Trustee, a list, in
such form as the Depositor, the Certificate Paying Agent or the Owner Trustee,
as the case may be, may reasonably require, of the names and addresses of the
Certificateholders as of the most recent Record Date. Each Holder, by receiving
and holding a Certificate, shall be deemed to have agreed not to hold any of the
Trust, the Depositor, the Certificate Paying Agent, the Certificate Registrar or
the Owner Trustee accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

      Section 3.09. Maintenance of Office or Agency. The Owner Trustee on behalf
of the Trust, shall maintain an office or offices or agency or agencies where
Certificates may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Owner Trustee in respect of the
Certificates and the Basic Documents may be served. The Owner Trustee initially
designates the office of the agent of the Indenture Trustee at
_________________________ for purposes of such surrender and the Corporate Trust
Office of the Indenture Trustee as its office for such purposes, service of
notices or demands. The Owner Trustee shall give prompt written notice to the
Depositor, the Certificate Paying Agent, the Certificate Registrar and the
Certificateholders of any change in the location of the Certificate Register or
any such office or agency.

      Section 3.10. Certificate Paying Agent. (a) The Certificate Paying Agent
shall make distributions to Certificateholders from the Certificate Distribution
Account on behalf of the Trust in accordance with the provisions of the
Certificates and Section 5.01 hereof from payments remitted to the Certificate
Paying Agent by the Indenture Trustee pursuant to Section 4.02 of the Indenture.
The Trust hereby appoints [CERTIFICATE PAYING AGENT] as Certificate Paying Agent
and [CERTIFICATE PAYING AGENT] hereby accepts such appointment and further
agrees that it will be bound by the provisions of this Trust Agreement relating
to the Certificate Paying Agent and shall:

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

                                       13
<PAGE>
            (ii) give the Owner Trustee notice of any default by the Trust of
      which a Responsible Officer of the Certificate Paying Agent has actual
      knowledge in the making of any payment required to be made with respect to
      the Certificates;

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

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

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

      (b) The Trust may revoke such power and remove the Certificate Paying
Agent if it determines in its sole discretion that the Certificate Paying Agent
shall have failed to perform its obligations under this Trust Agreement in any
material respect. In the event that [_____________] shall no longer be the
Certificate Paying Agent under this Trust Agreement and Paying Agent under the
Indenture, the Owner Trustee shall appoint a successor to act as Certificate
Paying Agent (which shall be a bank or trust company) and which shall also be
the successor Paying Agent under the Indenture. The Owner Trustee shall cause
such successor Certificate Paying Agent or any additional Certificate Paying
Agent appointed by the Owner Trustee to execute and deliver to the Owner Trustee
an instrument to the effect set forth in Section 3.10(a) as it relates to the
Certificate Paying Agent. The Certificate Paying Agent shall return all
unclaimed funds to the Trust and upon removal of a Certificate Paying Agent such
Certificate Paying Agent shall also return all funds in its possession to the
Trust. The provisions of Sections 6.01, 6.04, 6.05, 6.06, 6.07, 6.08 and 7.01
shall apply to the Certificate Paying Agent to the extent applicable. Any
reference in this Agreement to the Certificate Paying Agent shall include any
co-paying agent unless the context requires otherwise.

      (c) The Certificate Paying Agent shall make all distributions to
Certificates, from moneys on deposit in the Payment Account, in accordance with
Section 5.01 of this Agreement and Section 4.02 of the Indenture.

                                   ARTICLE IV

                      Authority and Duties of Owner Trustee

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

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

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

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

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

                                       15
<PAGE>
Certificateholders, and the Owner Trustee shall have no liability to any Person
for such action or inaction.

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

Trustee. The Owner Trustee shall have no responsibility for filing any financing
or continuation statement many public office at anytime or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder or to prepare or file any Securities and Exchange Commission filing
for the Trust or to record this Trust Agreement or any Basic Document. The Owner
Trustee nevertheless agrees that it will, at its own cost and expense, promptly

Trust Estate that result from actions by, or claims against, the Owner Trustee
that are not related to the ownership or the administration of the Trust Estate.

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

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

      Section 4.06. Prior Notice to Certificateholders with Respect to Certain
Matters. With respect to the following matters, the Owner Trustee shall not take
action unless at least 30 days before the taking of such action, the Owner
Trustee shall have notified the Certificateholders in writing of the proposed
action and the Certificateholders shall not have notified the Owner Trustee in
writing prior to the 30th day after such notice is given that such
Certificateholders have withheld consent or provided alternative direction:

      (a) the initiation of any claim or lawsuit by the Trust (except claims or
lawsuits brought in connection with the collection of cash distributions due and
owing under the Mortgage Loans) and the compromise of any action, claim or
lawsuit brought by or against the

                                       16
<PAGE>
Trust (except with respect to the aforementioned claims or lawsuits for

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

circumstances where the consent of any Noteholder is required;

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

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

      Section 4.07. Action by Certificateholders with Respect to Certain
Matters. The Owner Trustee shall, as expressly provided in the Basic Documents,
sell the Mortgage Loans after the termination of the Indenture. The Owner
Trustee shall take the actions referred to in the preceding sentence only upon
written instructions signed by the Certificateholders.

      Section 4.08. Action by Certificateholders with Respect to Bankruptcy. The
Owner Trustee shall not have the power to commence a voluntary proceeding in
bankruptcy relating to the Trust without the unanimous prior approval of all

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

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

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

                                       17
<PAGE>
Notes in accordance with Section 8.07 of the Indenture and shall provide all
necessary notices on behalf of the Issuer to effect the foregoing, provided that
the Master Servicer shall deposit with the Indenture Trustee an amount equal to
the aggregate redemption price specified under Section 8.07 of the Indenture.
The Owner Trustee shall not have the power to exercise the right of the Issuer
to redeem the Notes pursuant to Section 8.07 of the Indenture, except as
provided above.

                           Application of Trust Funds

      Section 5.01. Distributions. (a) On each Payment Date, the Certificate
Paying Agent shall distribute to the Certificateholders, on a pro rata basis
based on the Certificate Percentage Interests thereof, payments to the
Certificateholders (as provided in Section 4.02 of the Indenture) for such
Payment Date as reduced by any amount owing to the Owner Trustee hereunder and
any Expenses of the Trust remaining unpaid.

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

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

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

      Section 5.03. Tax Returns. The Indenture Trustee shall (a) maintain (or
cause to be maintained) the books of the Trust on a calendar year basis using
the accrual method of accounting, (b) deliver (or cause to be delivered) to each
Noteholder and Certificateholder as may be required by the Code and applicable
Treasury Regulations, such information as may be required to enable each
Certificateholder to prepare its federal and state income tax returns, (c)
prepare and file or cause to be prepared and filed such tax returns relating to
the Trust as may be required by the Code and applicable Treasury Regulations
(making such elections as may from time to time be required or appropriate under
any applicable state or federal statutes, rules or regulations) and (d) collect
or cause to be collected any withholding tax as described in and in accordance
with Section 5.01 of this Trust Agreement with respect to income or
distributions to Certificateholders and prepare or cause to be prepared the
appropriate forms relating thereto;

                                       19
<PAGE>
provided, however, that the Indenture Trustee shall not be required to compute
the Issuer's gross income except to the extent it can do so without unreasonable
effort or expense based upon income statements furnished to it and provided,
further, that the Indenture Trustee shall not be required to prepare and file
partnership tax returns on behalf of the Issuer unless the Indenture Trustee
receives an opinion of counsel reasonably satisfactory to it (which shall not be
at the Indenture Trustee's expense, but shall be at the expense of the Depositor
or other party furnishing such opinion) as to the necessity of such filings. The
Depositor, the Owner Trustee and the initial holder of the Certificates intend
that the Trust be treated for federal income tax purposes as a "qualified REIT
subsidiary," within the meaning of the Code. The Indenture Trustee will perform
the calculation of accrual of original issue discount and the amortization of
premium on the Notes and the Certificates. The Seller will prepare and file any
income tax returns required for the Trust and make any other tax filings
required under the Code. The Owner Trustee shall sign all tax and information
returns prepared or caused to be prepared by the Indenture Trustee pursuant to
this Section 5.03 at the request of the Indenture Trustee, and in doing so shall
rely entirely upon, and shall have no liability for information or calculations
provided by, the Indenture Trustee.

Section 5.04. Statements to Certificateholders. On each Payment Date, the
Certificate Paying Agent shall make available to each Certificateholder the
statement or statements provided to the Owner Trustee and the Certificate Paying
Agent by the Indenture Trustee pursuant to Section 7.05 of the Indenture with
respect to such Payment Date; provided, however, that in the event that any
monthly statement is no longer available, at the request of any
Certificateholder, the Indenture Trustee will deliver such monthly statement to
such Certificateholder.

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

the Certificateholders promptly upon receipt of a written reasonable request
therefor, duplicates or copies of all reports, notices, requests, demands,

      Section 6.03. Representations and Warranties. [OWNER TRUSTEE] hereby
represents and warrants to the Depositor, for the benefit of the
Certificateholders, that:

compliance by it with any of the terms or provisions hereof will contravene any
federal or Delaware law, governmental rule or regulation governing the banking

constitute any default under its charter documents or bylaws or any indenture,
mortgage, contract, agreement or instrument to which it is a party or by which
any of its properties may be bound;

      (d) This Trust Agreement assuming due authorization, execution and
delivery by the Owner Trustee and the Depositor, constitutes a valid, legal and
binding obligation of the Owner Trustee, enforceable against it in accordance
with the terms hereof subject to applicable bankruptcy, insolvency,
reorganization, moratorium and other laws affecting the enforcement of
creditors' rights generally and to general principles of equity, regardless of
whether such enforcement is considered in a proceeding in equity or at law;

      (e) The Owner Trustee is not in default with respect to any order or
decree of any court or any order, regulation or demand of any Federal, state,
municipal or governmental

                                       22
<PAGE>
agency, which default might have consequences that would materially and
adversely affect the condition (financial or other) or operations of the Owner
Trustee or its properties or might have consequences that would materially
adversely affect its performance hereunder; and

      (f) No litigation is pending or, to the best of the Owner Trustee's
knowledge, threatened against the Owner Trustee which would prohibit its
entering into this Trust Agreement or performing its obligations under this
Trust Agreement.

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

signed by the proper party or parties. The Owner Trustee may accept a certified
copy of a resolution of the board of directors or other governing body of any
corporate party as conclusive evidence that such resolution has been duly
adopted by such body and that the same is in full force and effect. As to any
fact or matter the method of determination of which is not specifically
prescribed herein, the Owner Trustee may for all purposes hereof rely on a
certificate, signed by the president or any vice president or by the treasurer
or other authorized officers of the relevant party, as to such fact or matter
and such certificate shall constitute full protection to the Owner Trustee for
any action taken or omitted to be taken by it in good faith in reliance thereon.

performance of its duties and obligations under this Trust Agreement or the
Basic Documents, the Owner Trustee (i) may act directly or through its agents,
attorneys, custodians or nominees (including persons acting under a power of
attorney) pursuant to agreements entered into with any of them, and the Owner

attorneys, custodians or nominees (including persons acting under a power of
attorney) if such persons have been selected by the Owner Trustee with
reasonable care, and (ii) may consult with counsel, accountants and other
skilled persons to be selected with reasonable care and employed by it. The
Owner Trustee shall not be liable for anything done, suffered or omitted in good
faith by it in accordance with the opinion or advice of any such counsel,
accountants or other such Persons and not contrary to this Trust Agreement or
any Basic Document.

the correctness thereof. The Owner Trustee makes no representations as to the
validity or sufficiency of this Trust Agreement, of any Basic Document or of the
Certificates (other than the signatures of the Owner Trustee on the
Certificates) or the Notes, or of any Related Documents, or of MERS or the
MERS(R) System. The Owner Trustee shall at no time have any responsibility or
liability with respect to the sufficiency of the Trust

become the owner or pledgee of Certificates or Notes and may deal with the
Depositor, the Seller, the Certificate Paying Agent, the Certificate Registrar
and the Indenture Trustee in transactions with the same rights as it would have
if it were not Owner Trustee.

      Section 6.08. Payments from Trust Estate. All payments to be made by the
Owner Trustee under this Trust Agreement or any of the Basic Documents to which
the Owner Trustee is a party shall be made only from the income and proceeds of
the Trust Estate or from other amounts required to be provided by the
Certificateholders and only to the extent that the Owner Trust shall have
received income or proceeds from the Trust Estate or the Certificateholders to
make such payments in accordance with the terms hereof. [OWNER TRUSTEE], in its
individual capacity, shall not be liable for any amounts payable under this
Trust Agreement or any of the Basic Documents to which the Owner Trustee is a
party.

anything contained herein to the contrary, the Owner Trustee shall not be
required to take any action in any jurisdiction other than in the State of
Delaware if the taking of such action will, even after the appointment of a
co-trustee or separate trustee in accordance with Section 9.05 hereof, (i)
require the consent or approval or authorization or order of or the giving of
notice to, or the registration with or the taking of any other action in respect
of, any state or other governmental authority or agency of any jurisdiction

      (a) At the direction of the Seller, the Owner Trustee shall, on behalf of
the Trust, enter into derivative contracts for the benefit of the Certificates;

Affiliate of the Depositor. Any acquisition of a derivative contract shall be
accompanied by (i) an appropriate amendment to this Agreement, and (ii) any
Opinion of Counsel required by Section 10.01.

                                       24

derivative contracts payable by the derivative counterparty shall be distributed

(ii) contain a non-petition covenant provision from the derivative counterparty,
(iii) limit payment dates thereunder for payments, if any, by the Trust to
Payment Dates (iv) contain a provision limiting any cash payments due to the

and (iv) prohibit the derivative counterparty from "setting-off' or "netting"
other obligations of the Trust and its Affiliates against such derivative
counterparty's payment obligations thereunder.

      (e) The Seller shall determine, in its sole discretion, whether any

                          Compensation of Owner Trustee

      Section 7.01. Owner Trustee's Fees and Expenses. The Owner Trustee shall

separately agreed upon before the date hereof, and the Owner Trustee shall be
reimbursed by the Depositor or the Master Servicer for its reasonable expenses
hereunder and under the Basic Documents, including the reasonable compensation,

                         Termination of Trust Agreement

      Section 8.01. Termination of Trust Agreement. (a) This Trust Agreement
(other than Article VII) and the Trust shall terminate and be of no further
force or effect upon the earliest of (i) the final distribution of all moneys or
other property or proceeds of the Trust Estate in accordance with the terms of
the Indenture and this Trust Agreement, (ii) the distribution of all of the
assets of the Trust Estate, in accordance with written instructions provided to
the Owner Trustee by the Master Servicer, following the optional redemption of
the Notes by the Issuer pursuant to Section 8.07 of the Indenture and subject to
Article IX of the Sale and Servicing Agreement; provided in each case that all
amounts owing to the Noteholders to the extent payable from the Trust Estate or
proceeds thereof have been paid in full and that all obligations under the
Indenture have been discharged. The bankruptcy, liquidation, dissolution, death
or incapacity of any Certificateholder shall not (x) operate to terminate this
Trust Agreement or the Trust or (y) entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or the Trust Estate or (z) otherwise affect the rights, obligations and
liabilities of the parties hereto.

      (b) Except as provided in Section 8.01(a), neither the Depositor nor any
Certificateholder shall be entitled to revoke or terminate the Trust.

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

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

                                       28
<PAGE>
surrender of their Certificates, and the cost thereof shall be paid out of the
funds and other assets that shall remain subject to this Trust Agreement. Any
funds remaining in the Certificate Distribution Account after exhaustion of such
remedies shall be distributed by the Certificate Paying Agent to the Depositor.

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

             Successor Owner Trustees and Additional Owner Trustees

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

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

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

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

      Section 9.03. Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 9.02 shall execute, acknowledge and deliver to the
Indenture Trustee and to its predecessor Owner Trustee an instrument accepting
such appointment under this Trust Agreement, and thereupon the resignation or
removal of the predecessor Owner Trustee shall become effective, and such
successor Owner Trustee, without any further act, deed or

                                       30
<PAGE>
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor under this Trust Agreement, with like effect as
if originally named as Owner Trustee. The predecessor Owner Trustee shall upon
payment of its fees and expenses deliver to the successor Owner Trustee all
documents and statements and monies held by it under this Trust Agreement; and
the predecessor Owner Trustee shall execute and deliver such instruments and do
such other things as may reasonably be required for fully and certainly vesting
and confirming in the successor Owner Trustee all such rights, powers, duties
and obligations.

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

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

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

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

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

      (a) All rights, powers, duties and obligations conferred or imposed upon
the Owner Trustee shall be conferred upon and exercised or performed by the
Owner Trustee and such separate trustee or co-trustee jointly (it being
understood that such separate trustee or co-trustee is not authorized to act
separately without the Owner Trustee joining in such act), except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed, the Owner Trustee shall be incompetent or unqualified to
perform such act or acts, in

                                       31
<PAGE>
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 Owner Trustee;

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

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

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

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

an Opinion of Counsel addressed to the Owner Trustee, the Certificate Registrar
and the Certificate Paying Agent and obtained by the Master Servicer to the

Certificateholder, would not cause the Trust to be subject to an entity level
tax for federal income tax purposes.

      (b) If the purpose of the amendment (as detailed therein) is to correct
any mistake, eliminate any inconsistency, cure any ambiguity or deal with any
matter not covered (i.e. to give effect to the intent of the parties and, if
applicable, to the expectations of the Holders), it shall not be necessary to
obtain the consent of any Holders, but the Owner Trustee, the Certificate
Registrar and the Certificate Paying Agent shall be furnished with (A) a letter
from the Rating Agencies that the amendment will not result in the downgrading
or withdrawal of the rating then assigned to any Note or the rating then
assigned to any Note or (B) an Opinion of Counsel obtained by the Master
Servicer to the effect that such action will not adversely affect in any
material respect the interests of any Holders.

provision of the Trust Agreement other than as contemplated in (b) and (c)
above, the amendment shall require (A) an Opinion of Counsel obtained by the

downgrading or withdrawal of the rating then assigned to any Note or the rating
then assigned to any Note or (b) the consent of Holders of Certificates
evidencing a majority Percentage Interest of the Certificates and the Indenture
Trustee; provided, however, that no such amendment shall (i) reduce in any
manner the amount of, or delay the timing of, payments received that are
required to be distributed on any Certificate without the consent of the related
Certificateholder, or (ii) reduce the aforesaid percentage of Certificates the
Holders of which are required to consent to any such amendment, without the
consent of the Holders of all such Certificates then outstanding.

      (e) If the purpose of the amendment is to provide for the holding of any
of the Certificates in book-entry form, it shall require the consent of Holders
of all such Certificates

                                       33
<PAGE>
then outstanding; provided, that the Opinion of Counsel specified
in subparagraph (a) above shall not be required.

additional certificates representing an interest in the Trust, it shall not be

effect that such action will not adversely affect in any material respect the
interests of any Holders and (B) a letter from the Rating Agencies that the
amendment will not result in the downgrading or withdrawal of the rating then

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

      (h) In connection with the execution of any amendment to any agreement to
which the Trust is a party, other than this Trust Agreement, the Owner Trustee
shall be entitled to receive and conclusively rely upon an Opinion of Counsel to

Documents for the execution and delivery thereof by the Trust or the Owner
Trustee, as the case may be, have been satisfied.

Certificate Registrar or the Certificate Paying Agent may be entered into
without the consent of the affected party.

terminate this Trust Agreement or the trusts hereunder or entitle any transferee
to an accounting or to the transfer to it of legal title to any part of the

         The Trust was created pursuant to a Short Form Trust Agreement, dated

(the "Owner Trustee", which term includes any successor entity under the Trust
Agreement) (the "Short Form Trust Agreement") as amended and restated by the

pertinent provisions of which is set forth hereinafter. This Certificate is
issued under and is subject to the terms, provisions and conditions of the Trust
Agreement, to which Trust Agreement the Holder of this Certificate by virtue of
the acceptance hereof assents and by which such Holder is bound.

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

         There will be distributed on the 25th day of each month or, if such

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

         The Holder of this Certificate acknowledges and agrees that its rights
to receive distributions in respect of this Certificate are subordinated to the
rights of the Noteholders as described in the Indenture, dated as of
____________, between the Trust and [INDENTURE TRUSTEE], as Indenture Trustee
(the "Indenture").

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

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

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

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

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

                                      B-4
<PAGE>
shall not be an expense of the Trust, the Owner Trustee, the Certificate
Registrar, the Master Servicer, the Seller or the Depositor and which investment
letter states that, among other things, such transferee (1) is a "qualified
institutional buyer" as defined under Rule 144A, acting for its own account or
the accounts of other "qualified institutional buyers" as defined under Rule
144A, and (2) is aware that the proposed transferor intends to rely on the
exemption from registration requirements under the Securities Act of 1933, as
amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel
acceptable to and in form and substance satisfactory to the Certificate
Registrar and the Depositor that such transfer may be made pursuant to an
exemption, describing the applicable exemption and the basis therefor, from said
Act and laws or is being made pursuant to said Act and laws, which Opinion of
Counsel shall not be an expense of the Trust, the Owner Trustee, the Certificate
Registrar, the Master Servicer, the Seller or the Depositor and (b) the
transferee executes a representation letter, substantially in the form of
Exhibit D to the Agreement, and the transferor executes a representation letter,
substantially in the form of Exhibit F to the Agreement, each acceptable to and
in form and substance satisfactory to the Certificate Registrar and the
Depositor certifying the facts surrounding such transfer, which representation
letters shall not be an expense of the Trust, the Owner Trustee, the Certificate
Registrar, the Master Servicer, the Seller or the Depositor and (B) the
Certificate of Non-Foreign Status (in substantially the form attached to the
Agreement as Exhibit D) acceptable to and in form and substance reasonably
satisfactory to the Certificate Registrar and the Depositor, which certificate
shall not be an expense of the Trust, the Owner Trustee, the Certificate
Registrar, the Seller or the Depositor. The Holder of a Certificate desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trust, the
Owner Trustee, the Indenture Trustee, the Certificate Paying Agent, the
Certificate Registrar, the Master Servicer, the Seller and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

         No transfer of Certificates or any interest therein shall be made to
any Person unless the Depositor, the Owner Trustee, the Certificate Registrar,
the Seller and the Master Servicer are provided with an Opinion of Counsel which
establishes to the satisfaction of the Depositor, the Owner Trustee, the
Certificate Registrar, the Seller and the Master Servicer that the purchase of
Certificates is permissible under applicable law, will not constitute or result
in any prohibited transaction under ERISA or Section 4975 of the Code and will
not subject the Depositor, the Owner Trustee, the Certificate Registrar, the
Seller or the Master Servicer to any obligation or liability (including
obligations or liabilities under ERISA or Section 4975 of the Code) in addition
to those undertaken in the Trust Agreement, which Opinion of Counsel shall not
be an expense of the Depositor, the Owner Trustee, the Certificate Registrar,
the Seller or the Master Servicer. In lieu of such Opinion of Counsel, a Person
may provide a certification in the form of Exhibit G to the Agreement, which the
Depositor, the Owner Trustee, the Certificate Registrar, the Seller and the
Master Servicer may rely upon without further inquiry or investigation. Neither
an Opinion of Counsel nor a certification will be required in connection with
the initial transfer of any such Certificate by the Depositor to an affiliate of
the Depositor (in which case, the Depositor or any affiliate thereof shall have
deemed to have represented that such affiliate is not a Plan or a Person
investing Plan Assets of any Plan) and the Owner Trustee shall be entitled to
conclusively rely upon a representation (which, upon the request of the Owner
Trustee, shall be a written representation) from the Depositor of the status of
such transferee as an affiliate of the Depositor.

      No offer, sale, transfer, pledge, hypothecation or other disposition
(including any pledge, sale or transfer under a repurchase transaction or
securities loan) of any Certificate shall be made to any transferee unless,
prior to such disposition, the proposed transferor delivers to the Owner Trustee
and the Certificate Registrar an Opinion of Counsel, rendered by a law firm
generally recognized to be qualified to opine concerning the tax aspects of
asset securitization to the effect that such transfer (including any disposition
permitted following any default under any pledge or repurchase transaction) will
not cause the Trust to be no longer be treated for federal income tax purposes
as a "qualified REIT subsidiary" within the meaning of Section 856(i) of the
Code.

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

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

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

                             REVERSE OF CERTIFICATE

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

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

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

                                      B-8
<PAGE>
will be issued to the designated transferee. The initial Certificate Registrar
appointed under the Trust Agreement is [__________].

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

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

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

                    _______________________________________

      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 Owner
Trustee and the Depositor (as defined in the Amended and Restated Trust
Agreement (the "Agreement"), dated as of ____________, among Merrill Lynch
Mortgage Investors, Inc., as Depositor, [OWNER TRUSTEE], as Owner Trustee and
[____________], as Certificate Registrar and Certificate Paying Agent) pursuant
to Section 3.05 of the Agreement and [INDENTURE TRUSTEE], 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, 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

amount, the Buyer may have included securities owned by subsidiaries of the
Buyer, but only if such subsidiaries are consolidated with the Buyer in its
financial statements prepared in accordance with generally accepted accounting
principles and if the investments of such subsidiaries are managed under the
Buyer's direction. However, such securities were not included if the Buyer is a
majority-owned, consolidated subsidiary of another enterprise and the Buyer is
not itself a reporting company under the Securities Exchange Act of 1934.

Certificates are relying and will

<PAGE>
continue to rely on the statements made herein because one or more sales to the
Buyer may be in reliance on Rule 144A.

____________      ____________      Will the Buyer be purchasing the Rule 144A
    Yes                No           Securities only for the Buyer's own account?

that, in connection with any purchase of securities sold to the Buyer for 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 a trust certificate (the "Certificate") representing ___%
fractional undivided interest in [TRUST] (the "Trust") created pursuant to a
Trust Agreement, dated as of ____________ (such agreement, as amended by the
Amended and Restated Trust Agreement, dated ______________, being referred to
herein as the "Trust Agreement") among Merrill Lynch Mortgage Investors, Inc.
(the "Company"), [OWNER TRUSTEE], as Owner Trustee (the "Owner Trustee") and
[_________], as certificate registrar and certificate paying agent (the
"Certificate Registrar"). Initially capitalized terms used but not defined
herein have the meanings assigned to them in the Deposit Trust Agreement. The
Transferor hereby certifies, represents and warrants to, and covenants with, the
Company, the Owner Trustee and the Certificate Registrar that:

      Neither the Transferor nor anyone acting on its behalf has (a) offered,
pledged, sold, disposed of or otherwise transferred any Trust Certificate, any
interest in any Trust Certificate or any other similar security to any person in

disposition or other transfer of any Trust Certificate, any interest in any
Trust Certificate or any other similar security from any person in any manner,
(c) has otherwise approached or negotiated with respect to any Trust
Certificate, any interest in any Trust Certificate or any other similar security
with any person 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
Trust Certificates under the Securities Act of 1933 (the "Act"), that would
render the disposition of any Trust Certificate a violation of Section 5 of the
Act or any state securities law, or 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 Trust Certificate. The
Transferor has not and will not sell or otherwise transfer any of the Trust
Certificates, except in compliance with the provisions of the Trust Agreement.
