      In addition, no reduction of the Group I Senior Prepayment Percentage
shall occur on any Distribution Date unless, as of the last day of the month
preceding such Distribution Date, (A) the aggregate Scheduled Principal Balance
of the Mortgage Loans delinquent 60 days or more (including for this purpose any
such Mortgage Loans in foreclosure and Mortgage Loans with respect to which the
related Mortgaged Property has been acquired by the Trust), averaged over the
last six months, as a percentage of the sum of the aggregate Current Principal
Amount of the Subordinate Certificates does not exceed 50%; and (B) cumulative
Realized Losses on the Mortgage Loans do not exceed (a) 30% of the Original
Subordinate Principal Balance if such Distribution Date occurs between and

and (e) 50% of the Original Subordinate Principal Balance if such Distribution
Date occurs during or after September 2015.

      In addition, if on any Distribution Date the current weighted average of
the Subordinate Percentages is equal to or greater than two times the initial
weighted average of the Subordinate Percentages, and (a) the aggregate Scheduled
Principal Balance of the Mortgage Loans delinquent 60 days or more (including
for this purpose any such Mortgage Loans in foreclosure and bankruptcy and such

Balance and (ii) after the Distribution Date in August 2007 cumulative Realized
Losses on the Mortgage Loans as of the end of the related Prepayment Period do
not exceed 30% of the Original Subordinate Principal Balance, then, the Group I
Senior Prepayment Percentage for such Distribution Date will equal the Group I
Senior Percentage; provided, however, if on such Distribution Date the current
weighted average of the Subordinate Percentages is equal to or greater than two
times the initial weighted average of the Subordinate Percentages on or prior to
the Distribution Date occurring in August 2007 and the above delinquency and
loss tests are met, then the Group I Senior Prepayment Percentage for such
Distribution Date will equal the Group I Senior Percentage plus 50% of the Group
I Subordinate Percentage.

      Notwithstanding the foregoing, if on any Distribution Date, the
percentage, the numerator which is the aggregate Current Principal Amount of the
Senior Certificates immediately preceding such Distribution Date, and the
denominator of which is the Scheduled Principal Balance of the Mortgage Loans as

Distribution Date will equal 100%. On the Distribution Date on which the Current
Principal Amounts of the Group I Senior Certificates are reduced to zero, the
Group I Senior Prepayment Percentage shall be the minimum percentage sufficient
to effect such reduction and thereafter shall be zero.

      Group I Subordinate Percentage: On any Distribution Date, 100% minus the
Group I Senior Percentage.

      Group I Subordinate Prepayment Percentage: With respect to the Group I
Mortgage Loans, on any Distribution Date, 100% minus the Group I Senior
Prepayment Percentage, except that on any Distribution Date after the Current
Principal Amounts of the Group I Senior Certificates have each been reduced to
zero, if (a) the weighted average of the Subordinate Percentages on such
Distribution Date equals or exceeds two times the initial weighted average of
the Subordinate Percentages and (b) the aggregate Scheduled Principal Balance of
the Mortgage Loans delinquent 60 days or more (including for this purpose any
such Mortgage Loans in foreclosure and Mortgage Loans with respect to which the
related Mortgaged Property has been acquired by the Trust), averaged over the
last six months, as a percentage of the sum of the aggregate Current Principal
Amount of the Subordinate Certificates does not exceed 100%, the Group I
Subordinate Prepayment Percentage will equal 100%. If the test set forth in the
preceding sentence is not satisfied on any Distribution Date after the Current
Principal Amount of the Group I Senior Certificates have each been reduced to
zero, then the Group I Subordinate Prepayment Percentage will equal zero for
such Distribution Date.

      Group II Mortgage Loans: The Mortgage Loans identified as such on the
Mortgage Loan Schedule.

      Group II Senior Certificates: The Class II-A-1 Certificates and Class II-X

      In addition, no reduction of the Group II Senior Prepayment Percentage
shall occur on any Distribution Date unless, as of the last day of the month
preceding such Distribution Date, (A) the aggregate Scheduled Principal Balance
of the Mortgage Loans delinquent 60 days or more (including for this purpose any
such Mortgage Loans in foreclosure and Mortgage Loans with respect to which the

Distribution Date occurs between and including September 2014 and August 2015,
and (e) 50% of the Original Subordinate Principal Balance if such Distribution
Date occurs during or after August 2015.

      In addition, if on any Distribution Date the current weighted average of
the Subordinate Percentages is equal to or greater than two times the initial
weighted average of the Subordinate Percentages, and (a) the aggregate Scheduled
Principal Balance of the Mortgage Loans delinquent 60 days or more (including
for this purpose any such Mortgage Loans in foreclosure and bankruptcy and such
Mortgage Loans with respect to which the related Mortgaged Property has been
acquired by the Trust), averaged over the last six months, as a percentage of

Balance and (ii) after the Distribution Date in August 2007 cumulative Realized
Losses on the Mortgage Loans as of the end of the related Prepayment Period do

Senior Percentage; provided, however, if on such Distribution Date the current
weighted average of the Subordinate Percentages is equal to or greater than two

                          Conveyance of Mortgage Loans;
                        Original Issuance of Certificates

      Section 2.01 Conveyance of Mortgage Loans to Trustee.

      (a) The Depositor concurrently with the execution and delivery of this
Agreement, sells, transfers and assigns to the Trust without recourse all its
right, title and interest in and to (i) the Mortgage Loans identified in the
Mortgage Loan Schedule, including all interest and principal due with respect to
the Mortgage Loans after the Cut-off Date, but excluding any payments of
principal and interest due on or prior to the Cut-off Date; (ii) such assets as
shall from time to time be credited or are required by the terms of this
Agreement to be credited to the Master Servicer Collection Account, (iii) such
assets relating to the Mortgage Loans as from time to time may be held by the
Servicers in Protected Accounts, the Master Servicer in the Master Servicer
Collection Account and the Trustee in the Distribution Account, (iv) any REO
Property, (v) the Required Insurance Policies and any amounts paid or payable by
the insurer under any Insurance Policy (to the extent the mortgagee has a claim
thereto), (vi) the Mortgage Loan Purchase Agreement to the extent provided in
Subsection 2.03(a), (vii) the rights with respect to the Servicing Agreements as
assigned to the Trustee on behalf of the Certificateholders by the Assignment
Agreements, (viii) the Class R Deposit and (ix) any proceeds of the foregoing.
Although it is the intent of the parties to this Agreement that the conveyance
of the Depositor's right, title and interest in and to the Mortgage Loans and
other assets in the Trust Fund pursuant to this Agreement shall constitute a
purchase and sale and not a loan, in the event that such conveyance is deemed to
be a loan, it is the intent of the parties to this Agreement that the Depositor
shall be deemed to have granted to the Trustee a first priority perfected
security interest in all of the Depositor's right, title and interest in, to and
under the Mortgage Loans and other assets in the Trust Fund, and that this
Agreement shall constitute a security agreement under applicable law.

      (b) In connection with the above transfer and assignment, the Depositor
hereby delivers to the Custodian, as agent for the Trustee, with respect to each
Mortgage Loan:

            (i) the original Mortgage Note, endorsed without recourse to the
order of the Trustee and showing an unbroken chain of endorsements from the
originator thereof to the Person endorsing it to the Trustee, or lost note
affidavit together with a copy of the related Mortgage Note;

            (ii) the original Mortgage and, if the related Mortgage Loan is a
MOM Loan, noting the presence of the MIN and language indicating that such
Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original
is not available, a copy), with evidence of such recording indicated thereon (or
if clause (w) in the proviso below applies, shall be in recordable form);

            (iii) unless the Mortgage Loan is a MOM Loan, a certified copy of
the assignment (which may be in the form of a blanket assignment if permitted in
the jurisdiction in which the Mortgaged Property is located) to "U.S. Bank
National Association, as Trustee", with

                                       38
<PAGE>

evidence of recording with respect to each Mortgage Loan in the name of the
Trustee thereon (or if clause (w) in the proviso below applies or for Mortgage
Loans with respect to which the related Mortgaged Property is located in a state
other than Maryland or an Opinion of Counsel has been provided as set forth in
this Section 2.01(b), shall be in recordable form);

            (iv) all intervening assignments of the Security Instrument, if
applicable and only to the extent available to the Depositor with evidence of
recording thereon;

            (v) the original or a copy of the policy or certificate of primary
mortgage guaranty insurance, to the extent available, if any;

            (vi) the original policy of title insurance or mortgagee's
certificate of title insurance or commitment or binder for title insurance; and

            (vii) originals of all modification agreements, if applicable and
available.

provided, however, that in lieu of the foregoing, the Depositor may deliver to
the Custodian, as agent of the Trustee, the following documents, under the
circumstances set forth below: (w) in lieu of the original Security Instrument,
assignments to the Trustee or intervening assignments thereof which have been
delivered, are being delivered or will, upon receipt of recording information
relating to the Security Instrument required to be included thereon, be
delivered to recording offices for recording and have not been returned to the
Depositor in time to permit their delivery as specified above, the Depositor may
deliver a true copy thereof with a certification by the Depositor, on the face
of such copy, substantially as follows: "Certified to be a true and correct copy
of the original, which has been transmitted for recording"; (x) in lieu of the
Security Instrument, assignment to the Trustee or intervening assignments
thereof, if the applicable jurisdiction retains the originals of such documents
(as evidenced by a certification from the Depositor to such effect) the
Depositor may deliver photocopies of such documents containing an original
certification by the judicial or other governmental authority of the
jurisdiction where such documents were recorded; (y) in lieu of the Mortgage
Notes relating to the Mortgage Loans identified on Exhibit 5 to the Mortgage
Loan Purchase Agreement, the Depositor may deliver lost note affidavits from the
Seller; and (z) the Depositor shall not be required to deliver intervening
assignments or Mortgage Note endorsements between the related Underlying Seller
and the Seller, between the Seller and the Depositor, and between the Depositor
and the Trustee; and provided, further, however, that in the case of Mortgage
Loans which have been prepaid in full after the Cut-off Date and prior to the
Closing Date, the Depositor, in lieu of delivering the above documents, may
deliver to the Trustee or the Custodian, as its agent, a certification to such
effect and shall deposit all amounts paid in respect of such Mortgage Loans in
the Master Servicer Collection Account on the Closing Date. The Depositor shall
deliver such original documents (including any original documents as to which
certified copies had previously been delivered) to the Trustee or the Custodian,
as its agent, promptly after they are received. The Depositor shall cause the
Seller, at its expense, to cause each assignment of the Security Instrument to
the Trustee to be recorded not later than 180 days after the Closing Date,
unless (a) such recordation is not required by the Rating Agencies or an Opinion
of Counsel addressed to the Trustee has been provided to the Trustee (with a
copy to the Custodian) which states that recordation of such Security Instrument
is not required to protect the

                                       39
<PAGE>

interests of the Certificateholders in the related Mortgage Loans or (b) MERS is
identified on the Mortgage or on a properly recorded assignment of the Mortgage
as the mortgagee of record solely as nominee for the Seller and its successor
and assigns; provided, however, notwithstanding the foregoing, each assignment
shall be submitted for recording by the Seller in the manner described above, at
no expense to the Trust or the Trustee or the Custodian, as its agent, upon the
earliest to occur of: (i) reasonable direction by the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 25% of the
Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Seller and (iv) the
occurrence of a servicing transfer as described in Section 8.02 hereof.
Notwithstanding the foregoing, if the Seller fails to pay the cost of recording
the assignments, such expense will be paid by the Trustee and the Trustee shall
be reimbursed for such expenses by the Trust in accordance with Section 9.05.

      Section 2.02 Acceptance of Mortgage Loans by Trustee.

      (a) The Trustee acknowledges the sale, transfer and assignment of the
Trust Fund to it by the Depositor and receipt of, subject to further review and
the exceptions which may be noted pursuant to the procedures described below,
and declares that it holds, the documents (or certified copies thereof)
delivered to the Custodian, as its agent, pursuant to Section 2.01, and declares
that it will continue to hold those documents and any amendments, replacements
or supplements thereto and all other assets of the Trust Fund delivered to it as
Trustee in trust for the use and benefit of all present and future Holders of
the Certificates. On the Closing Date, the Custodian, with respect to the
Mortgage Loans, shall acknowledge with respect to each Mortgage Loan by delivery
to the Depositor and the Trustee of an Initial Certification receipt of the
Mortgage File, but without review of such Mortgage File, except to the extent
necessary to confirm that such Mortgage File contains the related Mortgage Note
or lost note affidavit. No later than 90 days after the Closing Date (or, with
respect to any Substitute Mortgage Loan, within five Business Days after the
receipt by the Trustee or Custodian thereof), the Trustee agrees, for the
benefit of the Certificateholders, to review or cause to be reviewed by the
Custodian on its behalf (under the Custodial Agreement), each Mortgage File
delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Depositor and the Trustee an Interim Certification. In
conducting such review, the Trustee or Custodian will ascertain whether all
required documents have been executed and received, and based on the Mortgage
Loan Schedule, whether those documents relate, determined on the basis of the
Mortgagor name, original principal balance and loan number, to the Mortgage
Loans it has received, as identified in the Mortgage Loan Schedule. In
performing any such review, the Trustee or the Custodian, as its agent, may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon. If the
Trustee or the Custodian, as its agent, finds any document constituting part of
the Mortgage File has not been executed or received, or to be unrelated,
determined on the basis of the Mortgagor name, original principal balance and
loan number, to the Mortgage Loans identified in Exhibit B or to appear
defective on its face (a "Material Defect"), the Trustee or the Custodian, as
its agent, shall promptly notify the Seller. In accordance with the Mortgage
Loan Purchase Agreement, the Seller shall correct or cure any such defect within
ninety (90) days from the date of notice from the Trustee or the Custodian, as
its agent, of the defect and if the Seller fails to correct or cure the defect
within such period, and such defect materially and adversely affects the
interests of the

                                       40
<PAGE>

Certificateholders in the related Mortgage Loan, the Trustee shall enforce the
Seller's obligation under the Mortgage Loan Purchase Agreement to, within 90
days from the Trustee's or the Custodian's notification, provide a Substitute
Mortgage Loan (if within two years of the Closing Date) or purchase such
Mortgage Loan at the Repurchase Price; provided that, if such defect would cause
the Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or repurchase must occur within 90 days
from the date such breach was discovered; provided, however, that if such defect
relates solely to the inability of the Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy because the
originals of such documents, or a certified copy have not been returned by the
applicable jurisdiction, the Seller shall not be required to purchase such
Mortgage Loan if the Seller delivers such original documents or certified copy
promptly upon receipt, but in no event later than 360 days after the Closing
Date. The foregoing repurchase obligation shall not apply in the event that the
Seller cannot deliver such original or copy of any document submitted for
recording to the appropriate recording office in the applicable jurisdiction
because such document has not been returned by such office; provided that the
Seller shall instead deliver a recording receipt of such recording office or, if
such receipt is not available, a certificate confirming that such documents have
been accepted for recording, and delivery to the Trustee or the Custodian, as
its agent, shall be effected by the Seller within thirty days of its receipt of
the original recorded document.

      (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Depositor and the Trustee a Final Certification.
In conducting such review, the Trustee or the Custodian, as its agent, will
ascertain whether an original of each document required to be recorded has been
returned from the recording office with evidence of recording thereon or a
certified copy has been obtained from the recording office. If the Trustee or
the Custodian, as its agent, finds a Material Defect, the Trustee or the
Custodian, as its agent, shall promptly notify the Seller (provided, however,
that with respect to those documents described in subsections (b)(iv), (v) and
(vii) of Section 2.01, the Trustee's and Custodian's obligations shall extend
only to the documents actually delivered to the Custodian pursuant to such
subsections). In accordance with the Mortgage Loan Purchase Agreement, the
Seller shall correct or cure any such defect within 90 days from the date of
notice from the Trustee or the Custodian, as its agent, of the Material Defect
and if the Seller is unable to cure such defect within such period, and if such
defect materially and adversely affects the interests of the Certificateholders
in the related Mortgage Loan, the Trustee shall enforce the Seller's obligation
under the Mortgage Loan Purchase Agreement to, within 90 days from the Trustee's
or Custodian's notification, provide a Substitute Mortgage Loan (if within two
years of the Closing Date) or purchase such Mortgage Loan at the Repurchase
Price, provided that, if such defect would cause the Mortgage Loan to be other
than a "qualified mortgage" as defined in Section 860G(a)(3) of the Code, any
such cure, repurchase or substitution must occur within 90 days from the date
such breach was discovered, provided, however, that if such defect relates
solely to the inability of the Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy, because the
originals of such documents or a certified copy, have not been returned by the
applicable jurisdiction, the Seller shall not be required to purchase such
Mortgage Loan, if the Seller delivers such original documents or certified copy
promptly upon receipt, but in no event later than 360 days after the

                                       41
<PAGE>

Closing Date. The foregoing repurchase obligation shall not apply in the event
that the Seller cannot deliver such original or copy of any document submitted
for recording to the appropriate recording office in the applicable jurisdiction
because such document has not been returned by such office; provided that the
Seller shall instead deliver a recording receipt of such recording office or, if
such receipt is not available, a certificate confirming that such documents have
been accepted for recording, and delivery to the Trustee or the Custodian, as
its agent, shall be effected by the Seller within thirty days of its receipt of
the original recorded document.

      (c) In the event that a Mortgage Loan is purchased by the Seller in
accordance with Subsections 2.02(a) or (b) above, the Seller shall remit to the
Master Servicer the Repurchase Price for deposit in the Master Servicer
Collection Account and the Seller shall provide to the Securities Administrator
and the Trustee written notification detailing the components of the Repurchase
Price. Upon deposit of the Repurchase Price in the Master Servicer Collection
Account, the Depositor shall notify the Trustee and the Custodian, as agent of
the Trustee (upon receipt of a Request for Release in the form of Exhibit D
attached hereto with respect to such Mortgage Loan), shall release to the Seller
the related Mortgage File and the Trustee shall execute and deliver all
instruments of transfer or assignment, without recourse, representation or
warranty, furnished to it by the Seller, as are necessary to vest in the Seller
title to and rights under the Mortgage Loan. Such purchase shall be deemed to
have occurred on the date on which the Repurchase Price in available funds is
received by the Trustee. The Trustee shall amend the Mortgage Loan Schedule,
which was previously delivered to it by the Depositor in a form agreed to
between the Depositor and the Trustee, to reflect such repurchase and shall
promptly notify the Rating Agencies and the Master Servicer of such amendment.
The obligation of the Seller to repurchase or substitute for any Mortgage Loan a
Substitute Mortgage Loan as to which such a defect in a constituent document
exists shall be the sole remedy respecting such defect available to the
Certificateholders or to the Trustee on their behalf.

      Section 2.03 Assignment of Interest in the Mortgage Loan Purchase
Agreement.

      (a) The Depositor hereby assigns to the Trustee, on behalf of the
Certificateholders, all of its right, title and interest in the Mortgage Loan
Purchase Agreement, including but not limited to the Depositor's rights and
obligations pursuant to the Servicing Agreements (noting that the Seller has
retained the right in the event of breach of the representations, warranties and
covenants, if any, with respect to the related Mortgage Loans of the related
Servicer under the related Servicing Agreement to enforce the provisions thereof
and to seek all or any available remedies). The obligations of the Seller to
substitute or repurchase, as applicable, a Mortgage Loan shall be the Trustee's
and the Certificateholders' sole remedy for any breach thereof. At the request
of the Trustee, the Depositor shall take such actions as may be necessary to
enforce the above right, title and interest on behalf of the Trustee and the
Certificateholders or shall execute such further documents as the Trustee may
reasonably require in order to enable the Trustee to carry out such enforcement.

      (b) If the Depositor, the Securities Administrator or the Trustee
discovers a breach of any of the representations and warranties set forth in the
Mortgage Loan Purchase Agreement, which breach materially and adversely affects
the value of the interests of Certificateholders or the Trustee in the related
Mortgage Loan, the party discovering the breach shall give prompt

                                       42
<PAGE>

written notice of the breach to the other parties. The Seller, within 90 days of
its discovery or receipt of notice that such breach has occurred (whichever
occurs earlier), shall cure the breach in all material respects or, subject to
the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, shall purchase the Mortgage Loan or any property acquired with
respect thereto from the Trustee; provided, however, that if there is a breach
of any representation set forth in the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the
related property acquired with respect thereto has been sold, then the Seller
shall pay, in lieu of the Repurchase Price, any excess of the Repurchase Price
over the Net Liquidation Proceeds received upon such sale. If the Net
Liquidation Proceeds exceed the Repurchase Price, any excess shall be paid to
the Seller to the extent not required by law to be paid to the borrower. Any
such purchase by the Seller shall be made by providing an amount equal to the
Repurchase Price to the Master Servicer for deposit in the Master Servicer
Collection Account and written notification detailing the components of such
Repurchase Price. The Depositor shall notify the Trustee and submit to the
Custodian, as agent for the Trustee, a Request for Release, and the Custodian
shall release, or the Trustee shall cause the Custodian to release, to the
Seller the related Mortgage File and the Trustee shall execute and deliver all
instruments of transfer or assignment furnished to it by the Seller, without
recourse, representation or warranty as are necessary to vest in the Seller
title to and rights under the Mortgage Loan or any property acquired with
respect thereto. Such purchase shall be deemed to have occurred on the date on
which the Repurchase Price in available funds is received by the Trustee. The
Master Servicer shall amend the Mortgage Loan Schedule to reflect such
repurchase and shall promptly notify the Trustee and the Rating Agencies of such
amendment. Enforcement of the obligation of the Seller to purchase (or
substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property
acquired with respect thereto (or pay the Repurchase Price as set forth in the
above proviso) as to which a breach has occurred and is continuing shall
constitute the sole remedy respecting such breach available to the
Certificateholders or the Trustee on their behalf.

      Section 2.04 Substitution of Mortgage Loans.

      Notwithstanding anything to the contrary in this Agreement, in lieu of
purchasing a Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement or
Sections 2.02 or 2.03 of this Agreement, the Seller may, no later than the date
by which such purchase by the Seller would otherwise be required, tender to the
Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized
officer of the Seller that such Substitute Mortgage Loan conforms to the
requirements set forth in the definition of "Substitute Mortgage Loan" in this
Agreement; provided, however, that substitution pursuant to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of
purchase shall not be permitted after the termination of the two-year period
beginning on the Startup Day; provided, further, that if the breach would cause
the Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or substitution must occur within 90 days
from the date the breach was discovered. The Custodian, as agent for the
Trustee, shall examine the Mortgage File for any Substitute Mortgage Loan in the
manner set forth in Section 2.02(a) and the Trustee or the Custodian, as its
agent, shall notify the Seller, in writing, within five Business Days after
receipt, whether or not the documents relating to the Substitute Mortgage Loan
satisfy the requirements of the fifth sentence of Subsection 2.02(a). Within two
Business Days after

                                       43
<PAGE>

such notification, the Seller shall provide to the Trustee for deposit in the
Distribution Account the amount, if any, by which the Outstanding Principal
Balance as of the next preceding Due Date of the Mortgage Loan for which
substitution is being made, after giving effect to the Scheduled Principal due
on such date, exceeds the Outstanding Principal Balance as of such date of the
Substitute Mortgage Loan, after giving effect to Scheduled Principal due on such
date, which amount shall be treated for the purposes of this Agreement as if it
were the payment by the Seller of the Repurchase Price for the purchase of a
Mortgage Loan by the Seller. After such notification to the Seller and, if any
such excess exists, upon receipt of such deposit, the Trustee shall accept such
Substitute Mortgage Loan which shall thereafter be deemed to be a Mortgage Loan
hereunder. In the event of such a substitution, accrued interest on the
Substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the Trust Fund and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon during
such month shall be the property of the Seller. The Scheduled Principal on a
Substitute Mortgage Loan due on the Due Date in the month of substitution shall
be the property of the Seller and the Scheduled Principal on the Mortgage Loan
for which the substitution is made due on such Due Date shall be the property of
the Trust Fund. Upon acceptance of the Substitute Mortgage Loan (and delivery to
the Custodian of a Request for Release for such Mortgage Loan), the Custodian,
as agent for the Trustee, shall release to the Seller the related Mortgage File
related to any Mortgage Loan released pursuant to the Mortgage Loan Purchase
Agreement or Section 2.04 of this Agreement, as applicable, and shall execute
and deliver all instruments of transfer or assignment, without recourse,
representation or warranty in form as provided to it as are necessary to vest in
the Seller title to and rights under any Mortgage Loan released pursuant to the
Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable. The Seller shall deliver to the Custodian the documents related to
the Substitute Mortgage Loan in accordance with the provisions of the Mortgage
Loan Purchase Agreement or Subsections 2.01(b) and 2.02(b) of this Agreement, as
applicable, with the date of acceptance of the Substitute Mortgage Loan deemed
to be the Closing Date for purposes of the time periods set forth in those
Subsections. The representations and warranties set forth in the Mortgage Loan
Purchase Agreement shall be deemed to have been made by the Seller with respect
to each Substitute Mortgage Loan as of the date of acceptance of such Mortgage
Loan by the Trustee. The Master Servicer shall amend the Mortgage Loan Schedule
to reflect such substitution and shall provide a copy of such amended Mortgage
Loan Schedule to the Trustee and the Rating Agencies.

      Section 2.05 Issuance of Certificates.

      (a) The Trustee acknowledges the assignment to it of the Mortgage Loans
and the other assets comprising the Trust Fund and, concurrently therewith, has
signed, and countersigned and delivered to the Depositor, in exchange therefor,
Certificates in such authorized denominations representing such Fractional
Undivided Interests as the Depositor has requested. The Trustee agrees that it
will hold the Mortgage Loans and such other assets as may from time to time be

                                  ARTICLE III
                 Administration and Servicing of Mortgage Loans

      Section 3.01 Master Servicer.

      The Master Servicer shall supervise, monitor and oversee the obligation of
the Servicers to service and administer their respective Mortgage Loans in
accordance with the terms of the applicable Servicing Agreements and shall have
full power and authority to do any and all things which it may deem necessary or
desirable in connection with such master servicing and administration. In
performing its obligations hereunder, the Master Servicer shall act in a manner
consistent with Accepted Master Servicing Practices. Furthermore, the Master
Servicer shall oversee and consult with each Servicer as necessary from
time-to-time to carry out the Master Servicer's obligations hereunder, shall
receive, review and evaluate all reports, information and other data provided to
the Master Servicer by each Servicer and shall cause each Servicer to perform
and observe the covenants, obligations and conditions to be performed or
observed by such Servicer under its applicable Servicing Agreement. The Master
Servicer shall independently and separately monitor each Servicer's servicing
activities with respect to each related Mortgage Loan, reconcile the results of
such monitoring with such information provided in the previous sentence on a
monthly basis and coordinate corrective adjustments to the Servicers' and Master
Servicer's records, and based on such reconciled and corrected information, the
Master Servicer shall provide such information to the Securities Administrator
as shall be necessary in order for it to prepare the statements specified in
Section 6.04, and prepare any other information and statements required to be
forwarded by the Master Servicer hereunder. The Master Servicer shall reconcile
the results of its Mortgage Loan monitoring with the actual remittances of the
Servicers pursuant to the applicable Servicing Agreements.

      The Trustee shall furnish the Servicers and the Master Servicer with any
powers of attorney and other documents in form as provided to it necessary or
appropriate to enable the Servicers and the Master Servicer to service and
administer the related Mortgage Loans and REO Property.

      The Trustee shall provide access to the records and documentation in
possession of the Trustee regarding the related Mortgage Loans and REO Property
and the servicing thereof to the Certificateholders, the FDIC, and the
supervisory agents and examiners of the FDIC, such access being afforded only
upon reasonable prior written request and during normal business hours at the
office of the Trustee; provided, however, that, unless otherwise required by
law, the Trustee shall not be required to provide access to such records and
documentation if the provision thereof would violate the legal right to privacy
of any Mortgagor. The Trustee shall allow representatives of the above entities
to photocopy any of the records and documentation and shall provide equipment
for that purpose at a charge that covers the Trustee's actual costs.

      The Trustee shall execute and deliver to the related Servicer and the
Master Servicer any court pleadings, requests for trustee's sale or other
documents necessary or desirable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or Security Instrument;
(iii) obtain

                                       47
<PAGE>

a deficiency judgment against the Mortgagor; or (iv) enforce any other rights or
remedies provided by the Mortgage Note or Security Instrument or otherwise
available at law or equity.

      Section 3.02 REMIC-Related Covenants.

      For as long as each REMIC shall exist, the Trustee and the Securities
Administrator shall act in accordance herewith to assure continuing treatment of
such REMIC as a REMIC, and the Trustee and the Securities Administrator shall
comply with any directions of the Depositor, the related Servicer or the Master
Servicer to assure such continuing treatment. In particular, the Trustee shall
not (a) sell or permit the sale of all or any portion of the Mortgage Loans or
of any investment of deposits in an Account unless such sale is as a result of a
repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has
received a REMIC Opinion addressed to the Trustee prepared at the expense of the
Trust Fund; and (b) other than with respect to a substitution pursuant to the
Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, accept any contribution to any REMIC after the Startup Day without
receipt of a REMIC Opinion addressed to the Trustee .

      Section 3.03 Monitoring of Servicers.

      (a) The Master Servicer shall be responsible for reporting to the Trustee
and the Depositor the compliance by each Servicer with its duties under the
related Servicing Agreement. In the review of each Servicer's activities, the
Master Servicer may rely upon an officer's certificate of the Servicer (or
similar document signed by an officer of the Servicer) with regard to such
Servicer's compliance with the terms of its Servicing Agreement. In the event
that the Master Servicer, in its judgment, determines that a Servicer (other
than Wells Fargo) should be terminated in accordance with its Servicing
Agreement, or that a notice should be sent pursuant to such Servicing Agreement
with respect to the occurrence of an event that, unless cured, would constitute
grounds for such termination, the Master Servicer shall notify the Depositor and
the Trustee thereof and the Master Servicer shall issue such notice or take such
other action as it deems appropriate. In the event that the Master Servicer, in
its judgment, determines that Wells Fargo should be terminated in accordance
with the Wells Fargo Servicing Agreement, or that a notice should be sent
pursuant to the Wells Fargo Servicing Agreement with respect to the occurrence
of an event that, unless cured, would constitute grounds for such termination,
the Master Servicer shall notify the Depositor and the Trustee thereof in
writing. Pursuant to its receipt of such written notification from the Master
Servicer, the Trustee shall issue such notice of termination to Wells Fargo or
take such other action as it deems appropriate.

      (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer other than
Wells Fargo fails to perform its obligations in accordance with the related
Servicing Agreement, subject to the preceding paragraph, terminate the rights
and obligations of such Servicer thereunder and act as servicer of the related
Mortgage Loans or to cause the Trustee to enter in to a new Servicing Agreement
with a successor Servicer selected by the Master Servicer; provided, however, it
is understood and acknowledged by the parties hereto that there will be a period
of transition (not to exceed 90 days) before the actual servicing functions can
be fully transferred to such successor Servicer. In the event that Wells Fargo
fails

                                       48
<PAGE>

to perform its obligations in accordance with the Wells Fargo Servicing
Agreement, subject to the preceding paragraph, the Master Servicer shall notify
the Trustee in writing of such failure. Pursuant to its receipt of such
notification from the Master Servicer, the Trustee shall terminate the rights
and obligations of Wells Fargo under the Wells Fargo Servicing Agreement and
enter in to a new Servicing Agreement with a successor Servicer selected by the
Trustee; provided, however, it is understood and acknowledged by the parties
hereto that there will be a period of transition (not to exceed 90 days) before
the actual servicing functions can be fully transferred to such successor
Servicer. In either event, such enforcement, including, without limitation, the
legal prosecution of claims, termination of Servicing Agreements and the pursuit
of other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the Master Servicer (or in the case Wells Fargo is
terminated as the Servicer, the Trustee) in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Master
Servicer shall pay the costs of such enforcement at its own expense, provided
that the Master Servicer shall not be required to prosecute or defend any legal
action except to the extent that the Master Servicer shall have received
reasonable indemnity for its costs and expenses in pursuing such action. In the
event that Wells Fargo is terminated as the Servicer, the Trustee shall pay the
costs of such enforcement at its own expense, subject to its right to be
reimbursed for such costs from the Distribution Account pursuant to Section
3.03(c), provided that the Trustee shall not be required to prosecute or defend
any legal action except to the extent that the Trustee shall have received
reasonable indemnity for its costs and expenses in pursuing such action. Nothing
herein shall impose any obligation on the part of the Trustee to assume or
succeed to the duties or obligations of Wells Fargo or the Master Servicer.

      (c) In the event that Wells Fargo is terminated as Servicer, to the extent
that the costs and expenses of the Trustee related to any termination of Wells
Fargo, or the enforcement or prosecution of related claims, rights or remedies,
or the appointment of a successor Servicer (including, without limitation, (i)
all legal costs and expenses and all due diligence costs and expenses associated
with an evaluation of the potential termination of the Wells Fargo as a result
of an event of default by Wells Fargo and (ii) all costs and expenses associated
with the complete transfer of servicing, including all servicing files and all
servicing data and the completion, correction or manipulation of such servicing
data as may be required by the successor servicer to correct any errors or
insufficiencies in the servicing data or otherwise to enable the successor
service to service the Mortgage Loans in accordance with the related Servicing
Agreement) are not fully and timely reimbursed by Wells Fargo after such
termination, the Trustee shall be entitled to reimbursement of such costs and
expenses from the Distribution Account (which the Master Servicer hereby agrees
to pay to the Trustee from the Distribution Account upon demand). In all other
cases, to the extent that the costs and expenses of the Master Servicer related
to any termination of a Servicer (other than Wells Fargo), appointment of a
successor Servicer or the transfer and assumption of servicing by the Master
Servicer with respect to any Servicing Agreement (including, without limitation,
(i) all legal costs and expenses and all due diligence costs and expenses
associated with an evaluation of the potential termination of the Servicer as a
result of an event of default by such Servicer and (ii) all costs and expenses
associated with the complete transfer of servicing, including all servicing
files and all servicing data and the completion, correction or manipulation of
such servicing data as may be required by the successor servicer to correct any
errors or insufficiencies in the servicing data or otherwise to enable the
successor service to service the Mortgage Loans in accordance with the related

                                       49
<PAGE>

Servicing Agreement) are not fully and timely reimbursed by the terminated
Servicer, the Master Servicer shall be entitled to reimbursement of such costs
and expenses from the Master Servicer Collection Account.

      (d) The Master Servicer shall require each Servicer to comply with the
remittance requirements and other obligations set forth in the related Servicing
Agreement.

      (e) If the Master Servicer acts as Servicer, it will not assume liability
for the representations and warranties of the Servicer (other than Wells Fargo),
if any, that it replaces.

      Section 3.04 Fidelity Bond.

      The Master Servicer, at its expense, shall maintain in effect a blanket
fidelity bond and an errors and omissions insurance policy, affording coverage
with respect to all directors, officers, employees and other Persons acting on
such Master Servicer's behalf, and covering errors and omissions in the
performance of the Master Servicer's obligations hereunder. The errors and
omissions insurance policy and the fidelity bond shall be in such form and
amount generally acceptable for entities serving as master servicers or
trustees.

      Section 3.05 Power to Act; Procedures.

      The Master Servicer shall master service the Mortgage Loans and shall have
full power and authority, subject to the REMIC Provisions and the provisions of
Article X hereof, to do any and all things that it may deem necessary or
desirable in connection with the master servicing and administration of the
Mortgage Loans, including but not limited to the power and authority (i) to
execute and deliver, on behalf of the Certificateholders and the Trustee,
customary consents or waivers and other instruments and documents, (ii) to
consent to transfers of any Mortgaged Property and assumptions of the Mortgage
Notes and related Mortgages, (iii) to collect any Insurance Proceeds and
Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing any Mortgage Loan, in each
case, in accordance with the provisions of this Agreement and the related
Servicing Agreement, as applicable; provided, however, that the Master Servicer
shall not (and, consistent with its responsibilities under Section 3.03, shall
not permit any Servicer to) knowingly or intentionally take any action, or fail
to take (or fail to cause to be taken) any action reasonably within its control
and the scope of duties more specifically set forth herein, that, under the
REMIC Provisions, if taken or not taken, as the case may be, would cause any
REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon
the Trust Fund (including but not limited to the tax on prohibited transactions
as defined in Section 860F(a)(2) of the Code and the tax on contributions to a
REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has
received an Opinion of Counsel (but not at the expense of the Master Servicer)
to the effect that the contemplated action would not cause any REMIC to fail to
qualify as a REMIC or result in the imposition of a tax upon any REMIC. The
Trustee shall furnish the Master Servicer, upon written request from a Servicing
Officer, with any powers of attorney empowering the Master Servicer or any
Servicer to execute and deliver instruments of satisfaction or cancellation, or
of partial or full release or discharge, and to foreclose upon or otherwise
liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
action relating to the Mortgage Loans

                                       50
<PAGE>

or the Mortgaged Property, in accordance with the applicable Servicing Agreement
and this Agreement, and the Trustee shall execute and deliver such other
documents, as the Master Servicer may request, to enable the Master Servicer to
master service and administer the Mortgage Loans and carry out its duties
hereunder, in each case in accordance with Accepted Master Servicing Practices
(and the Trustee shall have no liability for misuse of any such powers of
attorney by the Master Servicer or any Servicer). If the Master Servicer or the
Trustee has been advised that it is likely that the laws of the state in which
action is to be taken prohibit such action if taken in the name of the Trustee
or that the Trustee would be adversely affected under the "doing business" or
tax laws of such state if such action is taken in its name, the Master Servicer
shall join with the Trustee in the appointment of a co-trustee pursuant to
Section 9.11 hereof. In the performance of its duties hereunder, the Master
Servicer shall be an independent contractor and shall not, except in those
instances where it is taking action in the name of the Trustee, be deemed to be
the agent of the Trustee.

      Section 3.06 Due-on-Sale Clauses; Assumption Agreements.

      To the extent provided in the applicable Servicing Agreement, to the
extent Mortgage Loans contain enforceable due-on-sale clauses, the Master
Servicer shall cause the Servicers to enforce such clauses in accordance with
the applicable Servicing Agreement. If applicable law prohibits the enforcement
of a due-on-sale clause or such clause is otherwise not enforced in accordance
with the applicable Servicing Agreement, and, as a consequence, a Mortgage Loan
is assumed, the original Mortgagor may be released from liability in accordance
with the applicable Servicing Agreement.

      Section 3.07 Release of Mortgage Files.

      (a) Upon becoming aware of the payment in full of any Mortgage Loan, or
the receipt by any Servicer of a notification that payment in full has been
escrowed in a manner customary for such purposes for payment to
Certificateholders on the next Distribution Date, the Servicer will, if required
under the applicable Servicing Agreement (or if the Servicer does not, the
Master Servicer may), promptly furnish to the Custodian, on behalf of the
Trustee, two copies of a certification substantially in the form of Exhibit D
hereto signed by a Servicing Officer or in a mutually agreeable electronic
format which will, in lieu of a signature on its face, originate from a
Servicing Officer (which certification shall include a statement to the effect
that all amounts received in connection with such payment that are required to
be deposited in the Protected Account maintained by the applicable Servicer
pursuant to Section 4.01 or by the applicable Servicer pursuant to its Servicing
Agreement have been or will be so deposited) and shall request that the
Custodian, on behalf of the Trustee, deliver to the applicable Servicer the
related Mortgage File. Upon receipt of such certification and request, the
Custodian, on behalf of the Trustee, shall promptly release the related Mortgage
File to the applicable Servicer and the Trustee and Custodian shall have no
further responsibility with regard to such Mortgage File. Upon any such payment
in full, each Servicer is authorized, to give, as agent for the Trustee, as the
mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of
satisfaction (or assignment of mortgage without recourse) regarding the
Mortgaged Property subject to the Mortgage, which instrument of satisfaction or
assignment, as the case may be, shall be delivered to the Person or Persons
entitled thereto against receipt therefor of such payment, it being

                                       51
<PAGE>

understood and agreed that no expenses incurred in connection with such
instrument of satisfaction or assignment, as the case may be, shall be
chargeable to the Protected Account.

      (b) From time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan and in accordance with the applicable Servicing Agreement,
the Trustee shall execute such documents as shall be prepared and furnished to
the Trustee by a Servicer or the Master Servicer (in form reasonably acceptable
to the Trustee) and as are necessary to the prosecution of any such proceedings.
The Custodian, on behalf of the Trustee, shall, upon the request of a Servicer
or the Master Servicer, and delivery to the Custodian, on behalf of the Trustee,
of two copies of a request for release signed by a Servicing Officer
substantially in the form of Exhibit D (or in a mutually agreeable electronic
format which will, in lieu of a signature on its face, originate from a
Servicing Officer), release the related Mortgage File held in its possession or
control to the Servicer or the Master Servicer, as applicable. Such trust
receipt shall obligate the Servicer or the Master Servicer to return the
Mortgage File to the Custodian on behalf of the Trustee, when the need therefor
by the Servicer or the Master Servicer no longer exists unless the Mortgage Loan
shall be liquidated, in which case, upon receipt of a certificate of a Servicing
Officer similar to that hereinabove specified, the Mortgage File shall be
released by the Custodian, on behalf of the Trustee, to the Servicer or the
Master Servicer.

      Section 3.08 Documents, Records and Funds in Possession of Master Servicer
To Be Held for Trustee.

      (a) The Master Servicer shall transmit and each Servicer (to the extent
required by the related Servicing Agreement) shall transmit to the Trustee or
Custodian such documents and instruments coming into the possession of the
Master Servicer or such Servicer from time to time as are required by the terms
hereof, or in the case of the Servicers, the applicable Servicing Agreement, to
be delivered to the Trustee or Custodian. Any funds received by the Master
Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are
collected by the Master Servicer or by a Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit
of the Trustee and the Certificateholders subject to the Master Servicer's right
to retain or withdraw from the Master Servicer Collection Account the Master
Servicing Compensation and other amounts provided in this Agreement, and to the
right of each Servicer to retain its Servicing Fee and other amounts as provided
in the applicable Servicing Agreement. The Master Servicer shall, and (to the
extent provided in the applicable Servicing Agreement) shall cause each Servicer
to, provide access to information and documentation regarding the Mortgage Loans
to the Trustee, its agents and accountants at any time upon reasonable request
and during normal business hours, and to Certificateholders that are savings and
loan associations, banks or insurance companies, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of such Office
and Corporation or examiners of any other federal or state banking or insurance
regulatory authority if so required by applicable regulations of the Office of
Thrift Supervision or other regulatory authority, such access to be afforded
without charge but only upon reasonable request in writing and during normal
business hours at the offices of the Master Servicer designated by it. In
fulfilling such a request the Master Servicer shall not be responsible for
determining the sufficiency of such information.

                                       52
<PAGE>

      (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer, in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds
or Insurance Proceeds, shall be held by the Master Servicer for and on behalf of
the Trustee and the Certificateholders and shall be and remain the sole and
exclusive property of the Trustee; provided, however, that the Master Servicer
and each Servicer shall be entitled to setoff against, and deduct from, any such
funds any amounts that are properly due and payable to the Master Servicer or
such Servicer under this Agreement or the applicable Servicing Agreement.

      Section 3.09 Standard Hazard Insurance and Flood Insurance Policies.

      (a) For each Mortgage Loan, the Master Servicer shall enforce any
obligation of the Servicers under the related Servicing Agreements to maintain
or cause to be maintained standard fire and casualty insurance and, where
applicable, flood insurance, all in accordance with the provisions of the
related Servicing Agreements. It is understood and agreed that such insurance
shall be with insurers meeting the eligibility requirements set forth in the
applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

      (b) Pursuant to Section 4.01 and 4.02, any amounts collected by the
Servicers or the Master Servicer, or by any Servicer, under any insurance
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or released to the Mortgagor in
accordance with the applicable Servicing Agreement) shall be deposited into the
Master Servicer Collection Account, subject to withdrawal pursuant to Section
4.02 and 4.03. Any cost incurred by the Master Servicer or any Servicer in
maintaining any such insurance if the Mortgagor defaults in its obligation to do
so shall be added to the amount owing under the Mortgage Loan where the terms of
the Mortgage Loan so permit; provided, however, that the addition of any such
cost shall not be taken into account for purposes of calculating the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or such Servicer pursuant to Section 4.02 and 4.03.

      Section 3.10 Presentment of Claims and Collection of Proceeds.

      The Master Servicer shall (to the extent provided in the applicable
Servicing Agreement) cause the related Servicer to prepare and present on behalf
of the Trustee and the Certificateholders all claims under the Insurance
Policies and take such actions (including the negotiation, settlement,
compromise or enforcement of the insured's claim) as shall be necessary to
realize recovery under such policies. Any proceeds disbursed to the Master
Servicer (or disbursed to a Servicer and remitted to the Master Servicer) in
respect of such policies, bonds or contracts shall be promptly deposited in the
Master Servicer Collection Account upon receipt, except that any amounts
realized that are to be applied to the repair or restoration of the related
Mortgaged Property as a condition precedent to the presentation of claims on the
related Mortgage Loan to the insurer under any applicable Insurance Policy need
not be so deposited (or remitted).

                                       53

      Section 3.11 Maintenance of the Primary Mortgage Insurance Policies.

      (a) The Master Servicer shall not take, or permit any Servicer (to the
extent such action is prohibited under the applicable Servicing Agreement) to
take, any action that would result in noncoverage under any applicable Primary
Mortgage Insurance Policy of any loss which, but for the actions of the Master
Servicer or such Servicer, would have been covered thereunder. The Master
Servicer shall use its best reasonable efforts to cause each Servicer (to the
extent required under the related Servicing Agreement) to keep in force and
effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain
such insurance), primary mortgage insurance applicable to each Mortgage Loan in
accordance with the provisions of this Agreement and the related Servicing
Agreement, as applicable. The Master Servicer shall not, and shall not permit
any Servicer (to the extent required under the related Servicing Agreement) to,
cancel or refuse to renew any such Primary Mortgage Insurance Policy that is in
effect at the date of the initial issuance of the Mortgage Note and is required
to be kept in force hereunder except in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable.

      (b) The Master Servicer agrees to present, or to cause each Servicer (to
the extent required under the related Servicing Agreement) to present, on behalf
of the Trustee and the Certificateholders, claims to the insurer under any
Primary Mortgage Insurance Policies and, in this regard, to take such reasonable
action as shall be necessary to permit recovery under any Primary Mortgage
Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01
and 4.02, any amounts collected by the Master Servicer or any Servicer under any
Primary Mortgage Insurance Policies shall be deposited in the Master Servicer
Collection Account, subject to withdrawal pursuant to Sections 4.02 and 4.03.

      Section 3.12 Trustee to Retain Possession of Certain Insurance Policies
and Documents.

      The Trustee (or the Custodian, as directed by the Trustee), shall retain
possession and custody of the originals (to the extent available) of any Primary
Mortgage Insurance Policies, or certificate of insurance if applicable, and any
certificates of renewal as to the foregoing as may be issued from time to time
as contemplated by this Agreement. Until all amounts distributable in respect of
the Certificates have been distributed in full and the Master Servicer otherwise
has fulfilled its obligations under this Agreement, the Trustee (or its
Custodian, if any, as directed by the Trustee) shall also retain possession and
custody of each Mortgage File in accordance with and subject to the terms and
conditions of this Agreement. The Master Servicer shall promptly deliver or
cause to be delivered to the Trustee (or the Custodian, as directed by the

      Section 3.15 REO Property.

      (a) In the event the Trust Fund acquires ownership of any REO Property in

Certificateholders. The Master Servicer shall, to the extent provided in the
applicable Servicing Agreement, cause the applicable Servicer to sell any REO
Property as expeditiously as possible and in accordance with the provisions of
this Agreement and the related Servicing Agreement, as applicable. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall cause the
applicable Servicer to protect and conserve, such REO Property in the manner and
to the extent required by the applicable Servicing Agreement, in accordance with
the REMIC Provisions and in a manner that does not result in a tax on "net
income from foreclosure property" or cause such REO Property to fail to qualify
as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code.

      (b) The Master Servicer shall, to the extent required by the related
Servicing Agreement, cause the applicable Servicer to deposit all funds
collected and received in connection with the operation of any REO Property in

disposition of any REO Property, shall be entitled to reimbursement for any
related unreimbursed Monthly Advances and other unreimbursed advances as well as
any unpaid Servicing Fees from Liquidation Proceeds received in connection with
the final disposition of such REO Property; provided, that any such unreimbursed
Monthly Advances as well as any unpaid Servicing Fees may be reimbursed or paid,
as the case may be, prior to final disposition, out of any net rental income or
other net amounts derived from such REO Property.

      (d) To the extent provided in the related Servicing Agreement, the
Liquidation Proceeds from the final disposition of the REO Property, net of any
payment to the Master Servicer and the applicable Servicer as provided above
shall be deposited in the Protected Account on or prior to the Determination
Date in the month following receipt thereof and be remitted by wire transfer in
immediately available funds to the Master Servicer for deposit into

      (a) The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before March 1 of each year, commencing on March 1, 2005, an
Officer's Certificate, certifying that with respect to the period ending
December 31 of the prior year: (i) such Servicing Officer has reviewed the
activities of such Master Servicer during the preceding calendar year or portion
thereof and its performance under this Agreement, (ii) to the best of such
Servicing Officer's knowledge, based on such review, such Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
Agreement in all material respects throughout such year, or, if there has been a
default in the fulfillment of any such duties, responsibilities or obligations,
specifying each such default known to such Servicing Officer and the nature and
status thereof, (iii) nothing has come to the attention of such Servicing
Officer to lead such Servicing Officer to believe that any Servicer has failed
to perform any of its duties, responsibilities and obligations under its
Servicing Agreement in all material respects throughout such year, or, if there
has been a material default in the performance or fulfillment of any such
duties, responsibilities or obligations, specifying each such default known to
such Servicing Officer and the nature and status thereof.

      (b) Copies of such statements shall be provided to any Certificateholder
upon request, by the Master Servicer or by the Trustee at the Master Servicer's
expense if the Master Servicer failed to provide such copies (unless (i) the
Master Servicer shall have failed to provide the Trustee with such statement or
(ii) the Trustee shall be unaware of the Master Servicer's failure to provide
such statement).

      Section 3.17 Annual Independent Accountant's Servicing Report.

      If the Master Servicer has, during the course of any fiscal year, directly
serviced any of the Mortgage Loans, then the Master Servicer at its expense
shall cause a nationally recognized firm of independent certified public
accountants to furnish a statement to the Trustee, the Rating Agencies and the
Depositor on or before March 1 of each year, commencing on March 1, 2005 to the
effect that, with respect to the most recently ended fiscal year, such firm has
examined certain records and documents relating to the Master Servicer's
performance of its servicing obligations under this Agreement and pooling and
servicing and trust agreements in material respects similar to this Agreement
and to each other and that, on the basis of such examination conducted
substantially in compliance with the audit program for mortgages serviced for
Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers, such
firm is of the opinion that the Master Servicer's activities have been conducted
in compliance with this Agreement, or that such examination has disclosed no
material items of noncompliance except for (i) such exceptions as such firm
believes to be immaterial, (ii) such other exceptions as are set forth in such
statement and (iii) such exceptions that the Uniform Single Attestation Program
for Mortgage Bankers or the Audit Program for Mortgages Serviced by Freddie Mac
requires it to report. Copies of such statements shall be provided to any
Certificateholder upon request by the Master Servicer, or by the Trustee at the
expense of the Master Servicer if the Master Servicer

                                       56
<PAGE>

shall fail to provide such copies. If such report discloses exceptions that are
material, the Master Servicer shall advise the Trustee whether such exceptions
have been or are susceptible of cure, and will take prompt action to do so.

      Section 3.18 Reports Filed with Securities and Exchange Commission.

      Within 15 days after each Distribution Date, the Securities Administrator
shall, in accordance with industry standards, file with the Commission via the
Electronic Data Gathering and Retrieval System ("EDGAR"), a Form 8-K (or other
comparable Form containing the same or comparable information or other
information mutually agreed upon) with a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30 in any year, the Securities Administrator shall, in accordance with
industry standards and only if instructed by the Depositor, file a Form 15
Suspension Notice with respect to the Trust Fund, if applicable. Prior to (i)
March 15, 2005 and (ii) unless and until a Form 15 Suspension Notice shall have
been filed, prior to March 15 of each year thereafter, the Master Servicer shall
provide the Securities Administrator with a Master Servicer Certification,
together with a copy of the annual independent accountant's servicing report and
annual statement of compliance of each Servicer, in each case, required to be
delivered pursuant to the related Servicing Agreement, and, if applicable, the
annual independent accountant's servicing report and annual statement of
compliance to be delivered by the Master Servicer pursuant to Sections 3.16 and
3.17. Prior to (i) March 31, 2005, or such earlier filing date as may be
required by the Commission, and (ii) unless and until a Form 15 Suspension
Notice shall have been filed, March 31 of each year thereafter, or such earlier
filing date as may be required by the Commission, the Securities Administrator
shall file a Form 10-K, in substance conforming to industry standards, with
respect to the Trust. Such Form 10-K shall include the Master Servicer
Certification and other documentation provided by the Master Servicer pursuant
to the second preceding sentence. The Depositor hereby grants to the Securities
Administrator a limited power of attorney to execute and file each such document
on behalf of the Depositor. Such power of attorney shall continue until either
the earlier of (i) receipt by the Securities Administrator from the Depositor of
written termination of such power of attorney and (ii) the termination of the
Trust Fund. The Depositor agrees to promptly furnish to the Securities
Administrator, from time to time upon request, such further information, reports
and financial statements within its control related to this Agreement and the
Mortgage Loans as the Securities Administrator reasonably deems appropriate to
prepare and file all necessary reports with the Commission. The Securities
Administrator shall have no responsibility to file any items other than those
specified in this Section 3.18; provided, however, the Securities Administrator
will cooperate with the Depositor in connection with any additional filings with
respect to the Trust Fund as the Depositor deems necessary under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). Fees and expenses
incurred by the Securities Administrator in connection with this Section 3.18
shall not be reimbursable from the Trust Fund.

      Section 3.20 UCC.

      The Depositor shall inform the Trustee in writing of any Uniform
Commercial Code financing statements that were filed on the Closing Date in
connection with the Trust with stamped recorded copies of such financing
statements to be delivered to the Trustee promptly upon receipt by the
Depositor. The Trustee agrees to monitor and notify the Depositor if any
continuation statements for such Uniform Commercial Code financing statements
need to be filed. If directed by the Depositor in writing, the Trustee will file
any such continuation statements solely at the expense of the Depositor. The
Depositor shall file any financing statements or amendments thereto required by
any change in the Uniform Commercial Code.

      Section 3.21 Optional Purchase of Defaulted Mortgage Loans.

      (a) With respect to any Mortgage Loan which as of the first day of a
Calendar Quarter is delinquent in payment by 90 days or more or is an REO
Property, the Company shall have the right to purchase such Mortgage Loan from
the Trust at a price equal to the Repurchase Price; provided however (i) that
such Mortgage Loan is still 90 days or more delinquent or is an REO Property as
of the date of such purchase and (ii) this purchase option, if not theretofore
exercised, shall terminate on the date prior to the last day of the related
Calendar Quarter. This purchase option, if not exercised, shall not be
thereafter reinstated unless the delinquency is cured and the Mortgage Loan
thereafter again becomes 90 days or more delinquent or becomes an REO Property,
in which case the option shall again become exercisable as of the first day of
the related Calendar Quarter.

      (b) If at any time the Company remits to the Master Servicer a payment for
deposit in the Master Servicer Collection Account covering the amount of the
Repurchase Price for such a Mortgage Loan, and the Company provides to the
Trustee a certification signed by a Servicing Officer stating that the amount of
such payment has been deposited in the Master Servicer Collection Account, then
the Trustee shall execute the assignment of such Mortgage Loan to the Company at
the request of the Company without recourse, representation or warranty and the
Company shall succeed to all of the Trustee's right, title and interest in and
to such Mortgage Loan, and all security and documents relative thereto. Such
assignment shall be an assignment outright and not for security. The Company
will thereupon own such Mortgage, and all such security and documents, free of
any further obligation to the Trustee or the Certificateholders with respect
thereto.

a Servicer for Monthly Advances which have been recovered by subsequent
collections from the related Mortgagor; to remove amounts deposited in error; to
remove fees, charges or other such amounts deposited on a temporary basis; or to
clear and terminate the account at the termination of this Agreement in

Servicer shall deposit or cause to be deposited to the Distribution Account any
amount not required to be credited thereto, the Trustee, upon receipt of a
written request therefor signed by a Servicing Officer of the Master Servicer,
shall promptly transfer such amount to the Master Servicer, any provision herein
to the contrary notwithstanding.

      (c) The amount at any time credited to the Master Servicer Collection
Account may be invested, in the name of the Trustee, or its nominee, for the
benefit of the Certificateholders, in Permitted Investments as directed by
Master Servicer. All Permitted Investments shall mature or be subject to
redemption or withdrawal on or before, and shall be held until, the next
succeeding Distribution Account Deposit Date. Any and all investment earnings on
amounts on deposit in the Master Servicer Collection Account from time to time

      (b) On an ongoing basis, the Master Servicer shall withdraw from the
Master Servicer Collection Account (i) any expenses, costs and liabilities

and encumbrances of any creditors or depositors of the Trustee or the Master
Servicer (whether made directly, or indirectly through a liquidator or receiver
of the Trustee or the Master Servicer). The Distribution Account shall be an
Eligible Account. The amount at any time credited to the Distribution Account
shall be (i) held in cash and fully insured by the FDIC to the maximum coverage
provided thereby or (ii) invested in the name of the Trustee, in such Permitted
Investments as may be selected by the Master Servicer or deposited in demand
deposits with such depository institutions as may be selected by the Master
Servicer, provided that time deposits of such depository institutions would be a
Permitted Investment. All Permitted Investments shall mature or be subject to
redemption or withdrawal on or before, and shall be held until, the next
succeeding Distribution Date if the obligor for such Permitted Investment is the
Trustee or, if such obligor is any other Person, the Business Day preceding such
Distribution Date. All investment earnings on amounts on deposit in the
Distribution Account or benefit from funds uninvested therein from time to time
shall be for the account of the Master Servicer. The Master Servicer shall be

deposited therein, the Master Servicer shall take such action as may be
necessary to ensure that the Certificateholders shall be entitled to the
priorities afforded to such a trust account (in addition to a claim against the
estate of the Trustee) as provided by 12 U.S.C. ss. 92a(e), and applicable
regulations pursuant thereto, if applicable, or any applicable comparable state
statute applicable to state chartered banking corporations.

      Section 5.01 Certificates.

      (a) The Depository, the Depositor and the Trustee have entered into a
Depository Agreement dated as of the Closing Date (the "Depository Agreement").
Except for the Residual Certificates, the Private Certificates and the
Individual Certificates and as provided in Subsection 5.01(b), the Certificates
shall at all times remain registered in the name of the Depository or its
nominee and at all times: (i) registration of such Certificates may not be
transferred by the Trustee except to a successor to the Depository; (ii)
ownership and transfers of registration of such Certificates on the books of the
Depository shall be governed by applicable rules established by the Depository;
(iii) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants; (iv) the Trustee shall deal with the
Depository as representative of such Certificate Owners of the respective Class
of Certificates for purposes of exercising the rights of Certificateholders
under this Agreement, and requests and directions for and votes of such
representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; and (v) the Trustee may rely and shall
be fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants.

      The Residual Certificates and the Private Certificates are initially
Physical Certificates. If at any time the Holders of all of the Certificates of
one or more such Classes request that the Trustee cause such Class to become
Global Certificates, the Trustee and the Depositor will take such action as may
be reasonably required to cause the Depository to accept such Class or Classes
for trading if it may legally be so traded.

      All transfers by Certificate Owners of such respective Classes of
Book-Entry Certificates and any Global Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

      (b) If (i)(A) the Depositor advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Depositor is unable to locate a
qualified successor within 30 days or (ii) the Depositor at its option advises
the Trustee in writing that it elects to terminate the book-entry system through
the Depository, the Trustee shall request that the Depository notify all
Certificate Owners of the occurrence of any such event and of the availability
of definitive, fully registered Certificates to Certificate Owners requesting
the same. Upon surrender to the Trustee of the Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall issue the definitive Certificates. Neither the Depositor nor
the Trustee shall be liable for any delay in delivery of any instructions
required under this section and may conclusively rely on, and shall be protected
in relying on, such instructions.

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

(designated below), which will be uncertificated and non-transferable and are
hereby designated as the "regular interests" in REMIC I and have the principal

be distributed to such REMIC I Regular Interests such that the REMIC I
Subordinated Balance Ratio is maintained); and third, any remaining principal to
REMIC I Regular Interest ZZZ. Realized Losses on the Mortgage Loans shall be
applied after all distributions have been made on each Distribution Date first,

Interests, REMIC II Regular Interests and the Certificates.

      (e) With respect to each Distribution Date, each Class of Certificates
shall accrue interest during the related Interest Accrual Period. With respect
to each Distribution Date and each such Class of Certificates, interest shall be
calculated, on the basis of a 360-day year comprised of twelve 30-day months,
based upon the respective Pass-Through Rate set forth, or determined as
provided, above and the Current Principal Amount (or Notional Amount in the case
of the Interest Only Certificates) of such Class applicable to such Distribution
Date.

      (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2 and A-3. On original issuance, the Trustee shall sign,
countersign and shall deliver them at the direction of the Depositor. Pending
the preparation of definitive Certificates of any Class, the Trustee may sign
and countersign temporary Certificates that are printed, lithographed or
typewritten, in authorized denominations for Certificates of such Class,
substantially of the tenor

                                       70
<PAGE>

of the definitive Certificates in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers or authorized signatories executing such Certificates may determine, as
evidenced by their execution of such Certificates. If temporary Certificates are
issued, the Depositor will cause definitive Certificates to be prepared without
unreasonable delay. After the preparation of definitive Certificates, the
temporary Certificates shall be exchangeable for definitive Certificates upon
surrender of the temporary Certificates at the office of the Trustee, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Certificates, the Trustee shall sign and countersign and deliver in
exchange therefor a like aggregate principal amount, in authorized denominations
for such Class, of definitive Certificates of the same Class. Until so
exchanged, such temporary Certificates shall in all respects be entitled to the
same benefits as definitive Certificates.

      (g) Each Class of Book-Entry Certificates will be registered as a single
Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of (i) in the
case of the Senior Certificates (other than the Residual Certificates), $1,000
and in each case increments of $1.00 in excess thereof, and (ii) in the case of
the Offered Subordinate Certificates, $25,000 and increments of $1.00 in excess
thereof, except that one Certificate of each such Class may be issued in a
different amount so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Trustee shall execute and
countersign Physical Certificates all in an aggregate principal amount that
shall equal the Current Principal Amount of such Class on the Closing Date. The
Private Certificates shall be issued in certificated fully-registered form in
minimum dollar denominations of $25,000 and integral multiples of $1.00 in
excess thereof, except that one Private Certificate of each Class may be issued
in a different amount so that the sum of the denominations of all outstanding
Private Certificates of such Class shall equal the Current Principal Amount of
such Class on the Closing Date. The Residual Certificates shall each be issued
in certificated fully-registered form, each, in the denomination of $50. Each
Class of Global Certificates, if any, shall be issued in fully registered form
in minimum dollar denominations of $50,000 and integral multiples of $1.00 in
excess thereof, except that one Certificate of each Class may be in a different
denomination so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Trustee shall execute and
countersign (i) in the case of each Class of Offered Certificates, the
Certificate in the entire Current Principal Amount of the respective Class and
(ii) in the case of each Class of Private Certificates, Individual Certificates
all in an aggregate principal amount that shall equal the Current Principal
Amount of each such respective Class on the Closing Date. The Certificates
referred to in clause (i) and if at any time there are to be Global
Certificates, the Global Certificates shall be delivered by the Depositor to the
Depository or pursuant to the Depository's instructions, shall be delivered by
the Depositor on behalf of the Depository to and deposited with the DTC
Custodian. The Trustee shall sign the Certificates by facsimile or manual
signature and countersign them by manual signature on behalf of the Trustee by
one or more authorized signatories, each of whom shall be Responsible Officers
of the Trustee or its agent. A Certificate bearing the manual and facsimile
signatures of individuals who were the authorized signatories of the Trustee or
its agent at the time of issuance shall bind the Trustee,

                                       71
<PAGE>

notwithstanding that such individuals or any of them have ceased to hold such
positions prior to the delivery of such Certificate.

      (h) No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate the
manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

      (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

      (j) For federal income tax purposes, each REMIC shall have a tax year that
is a calendar year and shall report income on an accrual basis.

      (k) The Trustee on behalf of the Trust shall cause each REMIC to timely
elect to be treated as a REMIC under Section 860D of the Code. Any
inconsistencies or ambiguities in this Agreement or in the administration of any
Trust established hereby shall be resolved in a manner that preserves the
validity of such elections.

      (l) The following legend shall be placed on the Residual Certificates,
whether upon original issuance or upon issuance of any other Certificate of any
such Class in exchange therefor or upon transfer thereof:

            THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR

AMENDED, OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED,

      Section 5.02 Registration of Transfer and Exchange of Certificates.

      (a) The Trustee shall maintain at its Corporate Trust Office a Certificate
Register in which, subject to such reasonable regulations as it may prescribe,
the Trustee shall provide for the registration of Certificates and of transfers
and exchanges of Certificates as herein provided.

      (b) Subject to Subsection 5.01(a) and, in the case of any Global
Certificate or Physical Certificate upon the satisfaction of the conditions set
forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose, the Trustee
shall sign, countersign and shall deliver, in the name of the designated
transferee or transferees, a new Certificate of a like Class and aggregate
Fractional Undivided Interest, but bearing a different number.

      (c) By acceptance of an Individual Certificate, whether upon original
issuance or subsequent transfer, each holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth in the Securities
Legend and agrees that it will transfer such a Certificate only as provided
herein. In addition to the provisions of Subsection 5.02(h), the following
restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the
form of an Individual Certificate:

            (i) The Trustee shall register the transfer of an Individual
Certificate if the requested transfer is being made to a transferee who has
provided the Trustee with a Rule 144A Certificate or comparable evidence as to
its QIB status.

            (ii) The Trustee shall register the transfer of any Individual
Certificate if (x) the transferor has advised the Trustee in writing that the
Certificate is being transferred to an Institutional Accredited Investor; and
(y) prior to the transfer the transferee furnishes to the Trustee an Investment
Letter (and the Trustee shall be fully protected in so doing), provided that,

                                       73
<PAGE>

if based upon an Opinion of Counsel addressed to the Trustee to the effect that
the delivery of (x) and (y) above are not sufficient to confirm that the
proposed transfer is being made pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act
and other applicable laws, the Trustee shall as a condition of the registration
of any such transfer require the transferor to furnish such other
certifications, legal opinions or other information prior to registering the
transfer of an Individual Certificate as shall be set forth in such Opinion of
Counsel.

      (d) Subject to Subsection 5.02(h), so long as a Global Certificate of such
Class is outstanding and is held by or on behalf of the Depository, transfers of
beneficial interests in such Global Certificate, or transfers by holders of
Individual Certificates of such Class to transferees that take delivery in the
form of beneficial interests in the Global Certificate, may be made only in
accordance with this Subsection 5.02(d) and in accordance with the rules of the
Depository:

            (i) In the case of a beneficial interest in the Global Certificate
being transferred to an Institutional Accredited Investor, such transferee shall
be required to take delivery in the form of an Individual Certificate or
Certificates and the Trustee shall register such transfer only upon compliance
with the provisions of Subsection 5.02(c)(ii).

            (ii) In the case of a beneficial interest in a Class of Global
Certificates being transferred to a transferee that takes delivery in the form
of an Individual Certificate or Certificates of such Class, except as set forth
in clause (i) above, the Trustee shall register such transfer only upon
compliance with the provisions of Subsection 5.02(c)(i).

            (iii) In the case of an Individual Certificate of a Class being
transferred to a transferee that takes delivery in the form of a beneficial
interest in a Global Certificate of such Class, the Trustee shall register such
transfer if the transferee has provided the Trustee with a Rule 144A Certificate
or comparable evidence as to its QIB status.

            (iv) No restrictions shall apply with respect to the transfer or
registration of transfer of a beneficial interest in the Global Certificate of a
Class to a transferee that takes delivery in the form of a beneficial interest
in the Global Certificate of such Class; provided that each such transferee
shall be deemed to have made such representations and warranties contained in
the Rule 144A Certificate as are sufficient to establish that it is a QIB.

      (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest in
a Global Certificate of a Class for an Individual Certificate or Certificates of
such Class, an exchange of an Individual Certificate or Certificates of a Class
for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

                                       74
<PAGE>

            (i) A holder of a beneficial interest in a Global Certificate of a
Class may at any time exchange such beneficial interest for an Individual
Certificate or Certificates of such Class.

            (ii) A holder of an Individual Certificate or Certificates of a
Class may exchange such Certificate or Certificates for a beneficial interest in
the Global Certificate of such Class if such holder furnishes to the Trustee a
Rule 144A Certificate or comparable evidence as to its QIB status.

            (iii) A holder of an Individual Certificate of a Class may exchange
such Certificate for an equal aggregate principal amount of Individual
Certificates of such Class in different authorized denominations without any
certification.

      (f)   (i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Trustee shall cancel such Individual Certificate
and shall (or shall request the Depository to) endorse on the schedule affixed
to the applicable Global Certificate (or on a continuation of such schedule
affixed to the Global Certificate and made a part thereof) or otherwise make in
its books and records an appropriate notation evidencing the date of such
exchange or transfer and an increase in the certificate balance of the Global
Certificate equal to the certificate balance of such Individual Certificate
exchanged or transferred therefor.

            (ii) Upon acceptance for exchange or transfer of a beneficial
interest in a Global Certificate of a Class for an Individual Certificate of
such Class as provided herein, the Trustee shall (or shall request the
Depository to) endorse on the schedule affixed to such Global Certificate (or on
a continuation of such schedule affixed to such Global Certificate and made a
part thereof) or otherwise make in its books and records an appropriate notation
evidencing the date of such exchange or transfer and a decrease in the
certificate balance of such Global Certificate equal to the certificate balance
of such Individual Certificate issued in exchange therefor or upon transfer
thereof.

      (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

      (h) Subject to the restrictions on transfer and exchange set forth in this
Section 5.02, the holder of any Individual Certificate may transfer or exchange
the same in whole or in part (in an initial certificate balance equal to the
minimum authorized denomination set forth in Section 5.01(g) above or any
integral multiple of $1.00 in excess thereof) by surrendering such Certificate
at the Corporate Trust Office, or at the office of any transfer agent, together
with an executed instrument of assignment and transfer satisfactory in form and
substance to the Trustee in the case of transfer and a written request for
exchange in the case of exchange. The holder of a beneficial interest in a
Global Certificate may, subject to the rules and procedures of the Depository,
cause the Depository (or its nominee) to notify the Trustee in writing of a
request for transfer or exchange of such beneficial interest for an Individual
Certificate or Certificates. Following a proper request for transfer or
exchange, the Trustee shall, within five Business Days

                                       75
<PAGE>

of such request made at the Corporate Trust Office, sign, countersign and
deliver at the Corporate Trust Office, to the transferee (in the case of
transfer) or holder (in the case of exchange) or send by first class mail at the
risk of the transferee (in the case of transfer) or holder (in the case of
exchange) to such address as the transferee or holder, as applicable, may
request, an Individual Certificate or Certificates, as the case may require, for
a like aggregate Fractional Undivided Interest and in such authorized
denomination or denominations as may be requested. The presentation for transfer
or exchange of any Individual Certificate shall not be valid unless made at the
Corporate Trust Office by the registered holder in person, or by a duly
authorized attorney-in-fact.

      (i) At the option of the Certificateholders, Certificates may be exchanged
for other Certificates of authorized denominations of a like Class and aggregate
Fractional Undivided Interest, upon surrender of the Certificates to be
exchanged at the Corporate Trust Office; provided, however, that no Certificate
may be exchanged for new Certificates unless the original Fractional Undivided
Interest represented by each such new Certificate (i) is at least equal to the
minimum authorized denomination or (ii) is acceptable to the Depositor as
indicated to the Trustee in writing. Whenever any Certificates are so
surrendered for exchange, the Trustee shall sign and countersign and the Trustee
shall deliver the Certificates which the Certificateholder making the exchange
is entitled to receive.

      (j) If the Trustee so requires, every Certificate presented or surrendered
for transfer or exchange shall be duly endorsed by, or be accompanied by a
written instrument of transfer, with a signature guarantee, in form satisfactory
to the Trustee, duly executed by the holder thereof or his or her attorney duly
authorized in writing.

      (k) No service charge shall be made for any transfer or exchange of
Certificates, but the Trustee 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.

      (l) The Trustee shall cancel all Certificates surrendered for transfer or
exchange but shall retain such Certificates in accordance with its standard
retention policy or for such further time as is required by the record retention
requirements of the Securities Exchange Act of 1934, as amended, and thereafter
may destroy such Certificates.

      Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

      (a) If (i) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as it may require to save it harmless, and (iii) the Trustee has not
received notice that such Certificate has been acquired by a third Person, the
Trustee shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

                                       76
<PAGE>

      (b) Upon the issuance of any new Certificate under this Section 5.03, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

      Section 5.04 Persons Deemed Owners.

      Prior to due presentation of a Certificate for registration of transfer,
the Depositor, the Trustee and any agent of the Depositor or the Trustee may
treat the Person in whose name any Certificate is registered as the owner of
such Certificate for the purpose of receiving distributions pursuant to Section
6.01 and for all other purposes whatsoever. Neither the Depositor, the Trustee
nor any agent of the Depositor or the Trustee shall be affected by notice to the
contrary. No Certificate shall be deemed duly presented for a transfer effective
on any Record Date unless the Certificate to be transferred is presented no
later than the close of business on the third Business Day preceding such Record
Date.

      Section 5.05 Transfer Restrictions on Residual Certificates.

      (a) Residual Certificates, or interests therein, may not be transferred
without the prior express written consent of the Tax Matters Person and the
Depositor. As a prerequisite to such consent, the proposed transferee must
provide the Tax Matters Person, the Depositor and the Trustee with an affidavit
that the proposed transferee is a Permitted Transferee (and an affidavit that it
is a U.S. Person) as provided in Subsection 5.05(b).

      (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee and the Depositor an affidavit in the form attached
hereto as Exhibit E stating, among other things, that as of the date of such
transfer (i) such transferee is a Permitted Transferee and that (ii) such
transferee is not acquiring such Residual Certificate for the account of any
person who is not a Permitted Transferee. The Tax Matters Person shall not
consent to a transfer of a Residual Certificate if it has actual knowledge that
any statement made in the affidavit issued pursuant to the preceding sentence is
not true. Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to any Person who is not a Permitted Transferee, such transfer, sale
or other disposition shall be deemed to be of no legal force or effect
whatsoever and such Person shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Tax Matters Person or the Depositor shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with

                                       77
<PAGE>

respect to such purported Holder under the provisions of this Agreement so long
as the written affidavit referred to above was received with respect to such
transfer, and the Tax Matters Person, the Trustee and the Depositor, as
applicable, had no knowledge that it was untrue. The prior Holder shall be
entitled to recover from any purported Holder of a Residual Certificate that was
in fact not a permitted transferee under this Subsection 5.05(b) at the time it
became a Holder all payments made on such Residual Certificate. Each Holder of a
Residual Certificate, by acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this Subsection 5.05(b) and to any amendment
of this Agreement deemed necessary (whether as a result of new legislation or
otherwise) by counsel of the Tax Matters Person or the Depositor to ensure that
the Residual Certificates are not transferred to any Person who is not a
Permitted Transferee and that any transfer of such Residual Certificates will
not cause the imposition of a tax upon the Trust or cause any REMIC to fail to
qualify as a REMIC.

      (c) The Residual Certificates (including a beneficial interest therein)
may not be purchased by or transferred to any person who is not a United States
Person.

      (d) By accepting a Residual Certificate, the purchaser thereof agrees to
be a Tax Matters Person, and appoints the Securities Administrator to act as its
agent with respect to all matters concerning the tax obligations of the Trust.

      Section 5.06 Restrictions on Transferability of Certificates.

      (a) No offer, sale, transfer or other disposition (including pledge) of
any Certificate shall be made by any Holder thereof unless registered under the
Securities Act, or an exemption from the registration requirements of the
Securities Act and any applicable state securities or "Blue Sky" laws is
available and the prospective transferee (other than the Depositor) of such
Certificate signs and delivers to the Trustee an Investment Letter, if the
transferee is an Institutional Accredited Investor, in the form set forth as
Exhibit F-l hereto, or a Rule 144A Certificate, if the transferee is a QIB, in
the form set forth as Exhibit F-2 hereto. Notwithstanding the provisions of the
immediately preceding sentence, no restrictions shall apply with respect to the
transfer or registration of transfer of a beneficial interest in any Certificate
that is a Global Certificate of a Class to a transferee that takes delivery in
the form of a beneficial interest in the Global Certificate of such Class
provided that each such transferee shall be deemed to have made such
representations and warranties contained in the Rule 144A Certificate as are
sufficient to establish that it is a QIB. In the case of a proposed transfer of
any Certificate to a transferee other than a QIB, the Trustee may require an
Opinion of Counsel addressed to the Trustee that such transaction is exempt from
the registration requirements of the Securities Act. The cost of such opinion
shall not be an expense of the Trustee or the Trust Fund.

      (b) The Private Certificates shall each bear a Securities Legend.

      Section 5.07 ERISA Restrictions.

      (a) Subject to the provisions of subsection (b), no Residual Certificates
or Private Certificates may be acquired directly or indirectly by, or on behalf
of, an employee benefit plan or other retirement arrangement which is subject to
Title I of ERISA or Section 4975 of the

                                       78
<PAGE>

Code, unless the proposed transferee provides either (i) the Trustee, with an
Opinion of Counsel addressed to the Depositor, the Trustee, the Master Servicer
and the Securities Administrator (upon which they may rely) which is
satisfactory to the Trustee, which opinion will not be at the expense of the
Depositor, the Trustee, the Master Servicer or the Securities Administrator,
that the purchase of such Certificates by or on behalf of such Plan is
permissible under applicable law, will not constitute or result in a nonexempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Depositor, the Master Servicer, the Securities Administrator or the
Trustee to any obligation in addition to those undertaken in the Agreement or
(ii) in the case of the Class B-4, Class B-5 and Class B-6 Certificates, a
representation or certification to the Trustee (upon which the Trustee is
authorized to rely) to the effect that the proposed transfer and holding of such
a Certificate and the servicing, management and operation of the Trust: (I) will
not result in a prohibited transaction under Section 406 of ERISA or Section
4975 of the Code which is not covered under an individual or class prohibited
transaction exemption including but not limited to Department of Labor
Prohibited Transaction Exemption ("PTE") 84-14 (Class Exemption for Plan Asset
Transactions Determined by Independent Qualified Professional Asset Managers);
PTE 91-38 (Class Exemption for Certain Transactions Involving Bank Collective
Investment Funds); PTE 90-1 (Class Exemption for Certain Transactions Involving
Insurance Company Pooled Separate Accounts), PTE 95-60 (Class Exemption for
Certain Transactions Involving Insurance Company General Accounts), and PTCE
96-23 (Class Exemption for Plan Asset Transactions Determined by In-House Asset
Managers and (II) will not subject the Depositor, the Securities Administrator,
the Master Servicer or the Trustee to any obligation in addition to those
undertaken in the Agreement.

      (b) Any Person acquiring an interest in a Global Certificate which is a
Private Certificate, by acquisition of such Certificate, shall be deemed to have
represented to the Trustee that in the case of the Class B-4, Class B-5 and
Class B-6 Certificates, either: (i) it is not acquiring an interest in such
Certificate directly or indirectly by, or on behalf of, an employee benefit plan
or other retirement arrangement which is subject to Title I of ERISA or Section
4975 of the Code, or (ii) the transfer and holding of an interest in such
Certificate to that Person and the subsequent servicing, management and
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60 or PTE 96-23 and (II) will not subject the Depositor, the
Securities Administrator, the Master Servicer or the Trustee to any obligation
in addition to those undertaken in the Agreement.

      (c) Each beneficial owner of a Class B-1, Class B-2 or Class B-3
Certificate or any interest therein shall be deemed to have represented, by
virtue of its acquisition or holding of that certificate or interest therein,
that either (i) it is not a Plan or investing with "Plan Assets", (ii) it has
acquired and is holding such certificate in reliance on Prohibited Transaction
Exemption 90-30, as amended from time to time (the "Exemption"), and that it
understands that there are certain conditions to the availability of the
Exemption, including that the certificate must be rated, at the time of
purchase, not lower than "BBB-" (or its equivalent) by S&P or Moody's Investors
Service, Inc., and the certificate is so rated or (iii) (1) it is an insurance
company, (2) the source of funds used to acquire or hold the certificate or
interest therein is an "insurance company general account," as such term is
defined in Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the
conditions in Sections I and III of PTCE 95-60 have been satisfied.

                                       79
<PAGE>

      (d) Neither the Trustee, the Master Servicer nor the Securities
Administrator will be required to monitor, determine or inquire as to compliance
with the transfer restrictions with respect to the Global Certificates. Any
attempted or purported transfer of any Certificate in violation of the
provisions of Subsections (a) or (b) above shall be void ab initio and such
Certificate shall be considered to have been held continuously by the prior
permitted Certificateholder. Any transferor of any Certificate in violation of
such provisions, shall indemnify and hold harmless the Trustee, the Securities
Administrator and the Master Servicer from and against any and all liabilities,
claims, costs or expenses incurred by the Trustee, the Securities Administrator
or the Master Servicer as a result of such attempted or purported transfer. The
Trustee shall have no liability for transfer of any such Global Certificates in
or through book-entry facilities of any Depository or between or among
Depository Participants or Certificate Owners made in violation of the transfer
restrictions set forth herein.

      Section 5.08 Rule 144A Information.

      For so long as any Certificates are outstanding and are "restricted
securities" within the meaning of Rule 144(a)(3) of the Securities Act, (1) the
Depositor will provide or cause to be provided to any holder of such
Certificates and any prospective purchaser thereof designated by such a holder,

            (iv) on each Distribution Date, the Group IV Available Funds will be
distributed to the Group IV Senior Certificates as follows:

            first, to the Class IV-A Certificates, the Accrued Certificate
            Interest on such Class for such Distribution Date. As described

            (v) Except as provided in clauses (vi) and (vii) below, on each
Distribution Date on or prior to the Cross-Over Date, an amount equal to the sum
of any remaining Group I, Group II, Group III and Group IV Available Funds after
the distributions in clauses (i), (ii), (iii) and (iv) above will be distributed
sequentially, in the following order, to the Class B-1, Class B-2, Class B-3,
Class B-4, Class B-5 and Class B-6 Certificates, in each case up to an amount
equal to and in the following order: (A) the Accrued Certificate Interest
thereon for such Distribution Date, (B) any Accrued Certificate Interest thereon
remaining undistributed from previous

                                       82
<PAGE>

Distribution Dates and (C) such Class's Allocable Share for such Distribution
Date, in each case, to the extent of remaining Group I, Group II, Group III,
Group IV Available Funds.

            (vi) On each Distribution Date prior to the Cross-Over Date but
after the reduction of the Current Principal Amount of all of the Senior
Certificates of a Certificate Group to zero, the remaining Class or Classes of
Senior Certificates in the remaining Certificate Groups (other than the Interest
Only Certificates) will be entitled to receive in reduction of their Current
Principal Amounts, pro rata based upon their Current Principal Amounts
immediately prior to such Distribution Date, in addition to any Principal
Prepayments related to such remaining Senior Certificates' respective Loan Group
allocated to such Senior Certificates, 100% of the Principal Prepayments on any
Mortgage Loan in the Loan Group relating to the Class or Classes of Senior
Certificates of the fully repaid Certificate Group; provided, however, that if
(A) the weighted average of the Subordinate Percentages on such Distribution
Date equals or exceeds two times the initial weighted average of the Subordinate
Percentages and (B) the aggregate Scheduled Principal Balance of the Mortgage
Loans delinquent 60 days or more (including for this purpose any such Mortgage
Loans in foreclosure and bankruptcy and Mortgage Loans with respect to which the
related Mortgaged Property has been acquired by the Trust), averaged over the
last six months, as a percentage of the aggregate Current Principal Amount of
the Subordinate Certificates does not exceed 100%, then the additional
allocation of Principal Prepayments to the Senior Certificates in accordance
with this clause (vi) will not be made and 100% of the Principal Prepayments on
any Mortgage Loan in the Loan Group relating to the fully repaid Class or
Classes of Senior Certificates will be allocated to the Subordinate
Certificates.

            (vii) If on any Distribution Date on which the aggregate Current
Principal Amount of any Class or Classes of Senior Certificates would be greater
than the aggregate Scheduled Principal Balance of the Mortgage Loans in the
related Loan Group and any Subordinate Certificates are still outstanding, in
each case after giving effect to distributions to be made on such Distribution
Date, (A) 100% of amounts otherwise allocable to the Subordinate Certificates in
respect of principal will be distributed to such Class or Classes of Senior
Certificates (other than the Interest Only Certificates) in reduction of the
Current Principal Amounts thereof, until the aggregate Current Principal Amount
of such Class or Classes of Senior Certificates is an amount equal to the
aggregate Scheduled Principal Balance of the Mortgage Loans in the related Loan
Group, and (B) the Accrued Certificate Interest otherwise allocable to the
Subordinate Certificates on such Distribution Date will be reduced, if
necessary, and distributed to such Class or Classes of Senior Certificates in an
amount equal to the Accrued Certificate Interest for such Distribution Date on
the excess of (x) the aggregate Current Principal Amount of such Class or
Classes of Senior Certificates over (y) the aggregate Scheduled Principal
Balance of the Mortgage Loans in the related Loan Group. Any such reduction in
the Accrued Certificate Interest on the Subordinate Certificates will be
allocated in reverse order of the Subordinate Certificates numerical
designations, commencing with the Class B-6 Certificates.

      (b) If, after distributions have been made pursuant to priorities first
and second of clauses (a)(i), (ii), (iii) and (iv) above on any Distribution
Date, the remaining Group I, Group II, Group III or Group IV Available Funds are
less than the Group I, Group II, Group III and Group

                                       83
<PAGE>

IV Senior Optimal Principal Amounts, respectively, the Senior Optimal Principal
Amount for such Loan Group shall be reduced, and such remaining Available Funds
will be distributed on the related Senior Certificates (other than the Interest
Only Certificates), on a pro rata basis, on the basis of such reduced amount.

      (c) On each Distribution Date, any Available Funds remaining after payment
of interest and principal to the Classes of Certificates entitled thereto, as
described above, will be distributed to the Class R-III Certificates; provided
that if on any Distribution Date there are any Group I, Group II, Group III or
Group IV Available Funds remaining after payment of interest and principal to a
Class or Classes of Certificates entitled thereto, such amounts will be
distributed to the other Classes of Senior Certificates, pro rata, based upon
their Current Principal Amounts, until all amounts due to all Classes of Senior
Certificates have been paid in full, before any amounts are distributed to the
Class R-III Certificates.

      (d) For any Distribution Date, "pro rata" distributions among Classes of
Certificates in respect of Accrued Certificate Interest or unpaid Accrued
Certificate Interest will be made in proportion to the amount of Accrued
Certificate Interest or unpaid Accrued Certificate Interest, respectively, due
on such Classes for such Distribution Date. For any Distribution Date, "pro
rata" distributions among Classes of Certificates in respect of principal will
be made in proportion to the Current Principal Amount of such Classes
immediately prior to such Distribution Date.

      (e) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates after the Distribution Date on which the Current Principal
Amount or Notional Amount of such Certificate has been reduced to zero.

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

      (g) The expenses and fees of the Trust shall be paid by each of the
REMICs, to the extent that such expenses relate to the assets of each of such
respective REMICs, and all other expenses and fees of the Trust shall be paid
pro rata by each of the REMICs.

      Section 6.02 Allocation of Losses.

      (a) On or prior to each Determination Date, the Master Servicer shall
determine the amount of any Realized Loss in respect of each Mortgage Loan that
occurred during the immediately preceding calendar month, based on information
provided by the related Servicer.

      (b) With respect to any Certificates (other than the Interest Only
Certificates) on any Distribution Date, the principal portion of each Realized
Loss on a Mortgage Loan shall be allocated as follows:

            first, to the Class B-6 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

            second, to the Class B-5 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

            third, to the Class B-4 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

            fourth, to the Class B-3 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

            fifth, to the Class B-2 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

            sixth, to the Class B-1 Certificates until the Current Principal
      Amount thereof has been reduced to zero;

                  SEVENTH, if such loss is on (w) a Group I Mortgage Loan, to
         the Class I-A-2 Certificates until the Current Principal Amount thereof
         has been reduced to zero and then to the Class I-A-1 Certificates until
         the Current Principal Amount thereof has been reduced to zero; (x) a
         Group II Mortgage Loan, to the Class II-A-1 Certificates until the
         Current Principal Amount thereof has been reduced to zero; (y) a Group
         III Mortgage Loan, to the Class III-A Certificates until the Current
         Principal Amount of the Class III-A Certificates has been reduced to
         zero; or (z) a Group IV Mortgage Loan, to the Class IV-A Certificates
         until the Current Principal Amount of the Class IV-A Certificates has
         been reduced to zero; and

            eighth, to the Senior Certificates (other than the Interest Only
      Certificates and the Class R Certificates), on a pro rata basis.

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

                                       85
<PAGE>

      (d) Any Realized Losses allocated to a Class of Certificates shall be
allocated among the Certificates of such Class (other than the Interest Only
Certificates) in proportion to their respective Current Principal Amounts. Any
allocation of Realized Losses shall be accomplished by reducing the Current
Principal Amount of the related Certificates on the related Distribution Date.

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

      (f) On each Distribution Date, the Securities Administrator shall
determine and notify the Trustee of the Subordinate Certificate Writedown
Amount. Any Subordinate Certificate Writedown Amount shall effect a
corresponding reduction in the Current Principal Amount of (i) if prior to the
Cross-Over Date, the Current Principal Amounts of the Subordinate Certificates,
in the reverse order of their numerical Class designations and (ii) from and
after the Cross-Over Date, the Senior Certificates (other than the Interest Only
Certificates), in accordance with priorities set forth in clause (b) above,
which reduction shall occur on such Distribution Date after giving effect to
distributions made on such Distribution Date.

      (g) Any Net Interest Shortfall will be allocated among the Classes of
Certificates in proportion to the respective amounts of Accrued Certificate
Interest that would have been allocated thereto in the absence of such Net
Interest Shortfall for such Distribution Date. The interest portion of any
Realized Losses with respect to the Mortgage Loans occurring on or prior to the
Cross-Over Date will not be allocated among any Certificates, but will reduce
the amount of Available Funds on the related Distribution Date. As a result of
the subordination of the Subordinate Certificates in right of distribution, such
Realized Losses on the Mortgage Loans will be borne by the Subordinate
Certificates, in inverse order of their numerical Class designations. Following
the Cross- Over Date, the interest portion of Realized Losses on the Mortgage
Loans will be allocated to the Senior Certificates in the manner described in
the first sentence of this clause (g).

      (h) In addition, in the event that the Master Servicer receives any
Subsequent Recoveries from a Servicer, the Master Servicer shall deposit such
funds into the Master Servicer Collection Account pursuant to Section 4.02. If,
after taking into account such Subsequent Recoveries, the amount of a Realized
Loss is reduced, the amount of such Subsequent Recoveries will be applied to
increase the Current Principal Amount of the Class of Subordinate Certificates
with the highest payment priority to which Realized Losses have been allocated,
but not by more than the amount of Realized Losses previously allocated to that
Class of Subordinate Certificates pursuant to this Section 6.02. The amount of
any remaining Subsequent Recoveries will be applied to sequentially increase the
Current Principal Amount of the Subordinate Certificates, beginning with the
Class of Subordinate Certificates with the next highest payment priority, up to
the amount of such Realized Losses previously allocated to such Class of
Certificates pursuant to this Section 6.02. Holders of such Certificates will
not be entitled to any payment in respect of current interest on the amount of
such increases for any Interest Accrual Period preceding the Distribution Date
on which such increase occurs. Any such

                                       86
<PAGE>

increases shall be applied to the Current Principal Amount of each Subordinate
Certificate of such Class in accordance with its respective Fractional Undivided
Interest.

      Section 6.03 Payments.

      (a) On each Distribution Date, other than the final Distribution Date, the
Trustee shall distribute to each Certificateholder of record as of the
immediately preceding Record Date the Certificateholder's pro rata share of its
Class (based on the aggregate Fractional Undivided Interest represented by such
Holder's Certificates) of all amounts required to be distributed on such
Distribution Date to such Class, based on information provided to the Trustee by
the Securities Administrator. The Securities Administrator shall calculate the
amount to be distributed to each Class and, based on such amounts, the
Securities Administrator shall determine the amount to be distributed to each
Certificateholder. All of the Securities Administrator's calculations of
payments shall be based solely on information provided to the Securities
Administrator by the Master Servicer. Neither the Securities Administrator nor
the Trustee shall be required to confirm, verify or recompute any such
information but shall be entitled to rely conclusively on such information.

      (b) Payment of the above amounts to each Certificateholder shall be made
(i) by check mailed to each Certificateholder entitled thereto at the address
appearing in the Certificate Register or (ii) upon receipt by the Trustee on or
before the fifth Business Day preceding the Record Date of written instructions
from a Certificateholder by wire transfer to a United States dollar account
maintained by the payee at any United States depository institution with
appropriate facilities for receiving such a wire transfer; provided, however,
that the final payment in respect of each Class of Certificates will be made
only upon presentation and surrender of such respective Certificates at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final payment.

      Section 6.04 Statements to Certificateholders.

      (a) Concurrently with each distribution to Certificateholders, the
Securities Administrator shall make available to the parties hereto and each
Certificateholder via the Securities Administrator's internet website as set
forth below, the following information, expressed with respect to clauses (i)

      (b) By April 30 of each year beginning in 2005, the Trustee will furnish
such report to each Holder of the Certificates of record at any time during the
prior calendar year as to the aggregate of amounts reported pursuant to

shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Securities Administrator or the
Trustee pursuant to the requirements of the Code.

      Section 6.05 Monthly Advances.

      If the Scheduled Payment on a Mortgage Loan that was due on a related Due
Date is delinquent other than as a result of application of the Relief Act and
for which the related Servicer was required to make an advance pursuant to the
related Servicing Agreement exceeds the amount deposited in the Master Servicer
Collection Account which will be used for an advance with respect to such
Mortgage Loan, the Master Servicer will deposit in the Master Servicer
Collection Account not later than the Distribution Account Deposit Date
immediately preceding the related Distribution Date an amount equal to such
deficiency, net of the Servicing Fee for such Mortgage Loan except to the extent
the Master Servicer determines any such advance to be a Nonrecoverable Advance.
Subject to the foregoing, the Master Servicer shall continue to make such
advances through the date that the related Servicer is required to do so under
its Servicing Agreement. If the Master Servicer deems an advance to be a
Nonrecoverable Advance, on the Distribution Account Deposit Date, the Master
Servicer shall present an Officer's Certificate to the Trustee (i) stating that
the Master Servicer elects not to make a Monthly Advance in a stated amount and
(ii) detailing the reason it deems the advance to be a Nonrecoverable Advance.

      Section 6.06 Compensating Interest Payments.

      The Master Servicer shall deposit in the Master Servicer Collection
Account not later than each Distribution Account Deposit Date an amount equal to
the lesser of (i) the sum of the aggregate amounts required to be paid by the
Servicers under the Servicing Agreements with respect to subclauses (a) and (b)
of the definition of Interest Shortfall with respect to the Mortgage Loans for
the related Distribution Date, and not so paid by the related Servicers and (ii)
the Master Servicer Compensation for such Distribution Date (such amount, the
"Compensating Interest Payment"). The Master Servicer shall not be entitled to
any reimbursement of any Compensating Interest Payment.

                               The Master Servicer

      Section 7.01 Liabilities of the Master Servicer.

      The Master Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by it herein.

      Section 7.02 Merger or Consolidation of the Master Servicer.

      (a) The Master Servicer will keep in full force and effect its existence,
rights and franchises as a corporation under the laws of the state of its
incorporation, and will obtain and preserve its qualification to do business as
a foreign corporation in each jurisdiction in which such qualification is or
shall be necessary to protect the validity and enforceability of this Agreement,
the Certificates or any of the Mortgage Loans and to perform its duties under
this Agreement.

      (b) Any Person into which the Master Servicer may be merged or
consolidated, or any corporation resulting from any merger or consolidation to
which the Master Servicer shall be a party, or any Person succeeding to the
business of the Master Servicer, shall be the successor of the Master Servicer
hereunder, without the execution or filing of any paper or further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding.

      Section 7.03 Indemnification of the Trustee, the Master Servicer and the
Securities Administrator.

      (a) The Master Servicer agrees to indemnify the Indemnified Persons for,
and to hold them harmless against, any loss, liability or expense (including
reasonable legal fees and disbursements of counsel) incurred on their part that
may be sustained in connection with, arising out of, or relating to, any claim
or legal action (including any pending or threatened claim or legal action)
relating to this Agreement, the Servicing Agreements, the Assignment Agreements
or the Certificates or the powers of attorney delivered by the Trustee hereunder
(i) related to the Master Servicer's failure to perform its duties in compliance
with this Agreement (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) or (ii) incurred by reason of
the Master Servicer's willful misfeasance, bad faith or gross negligence in the
performance of its duties hereunder or by reason of reckless disregard of its
obligations and duties hereunder, provided, in each case, that with respect to
any such claim or legal action (or pending or threatened claim or legal action),
the Trustee shall have given the Master Servicer and the Depositor written
notice thereof promptly after the Trustee shall have with respect to such claim
or legal action knowledge thereof. The Master Servicer's failure to receive any
such notice shall not affect the Trustee's right to indemnification hereunder,
except to the extent the Master Servicer is materially prejudiced by such
failure to give notice. This indemnity shall survive the resignation or removal
of the Trustee, Master Servicer or the Securities Administrator and the
termination of this Agreement.

                                       91
<PAGE>

      (b) The Depositor will indemnify any Indemnified Person for any loss,
liability or expense of any Indemnified Person not otherwise covered by the
Master Servicer's indemnification pursuant to Subsection (a) above.

      Section 7.04 Limitations on Liability of the Master Servicer and Others.

      Subject to the obligation of the Master Servicer to indemnify the
Indemnified Persons pursuant to Section 7.03:

      (a) Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Indemnified Persons, the Depositor, the Trust Fund or the Certificateholders for
taking any action or for refraining from taking any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Master Servicer or any such Person against
any breach of warranties or representations made herein or any liability which
would otherwise be imposed by reason of such Person's willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder.

      (b) The Master Servicer and any director, officer, employee or agent of
the Master Servicer may rely in good faith on any document of any kind prima
facie properly executed and submitted by any Person respecting any matters
arising hereunder.

      (c) The Master Servicer, the Custodian and any director, officer, employee
or agent of the Master Servicer or the Custodian, and the Trustee to the extent
it becomes party to the Wells Fargo Servicing Agreement pursuant to Section
3.03, and any director, officer, employee or agent of the Trustee, shall be
indemnified by the Trust and held harmless thereby against any loss, liability
or expense (including reasonable legal fees and disbursements of counsel)
incurred on their part that may be sustained in connection with, arising out of,
or related to, any claim or legal action (including any pending or threatened
claim or legal action) relating to this Agreement, the Certificates or any
Servicing Agreement (except to the extent that the Master Servicer or Trustee,
as the case may be, is indemnified by the Servicer thereunder), other than (i)
any such loss, liability or expense related to the Master Servicer's failure to
perform its duties in compliance with this Agreement (except as any such loss,
liability or expense shall be otherwise reimbursable pursuant to this
Agreement), or to the Custodian's failure to perform its duties under the
Custodial Agreeement, respectively, or (ii) any such loss, liability or expense
incurred by reason of the Master Servicer's or the Custodian's willful
misfeasance, bad faith or gross negligence in the performance of duties
hereunder or under the Custodial Agreement, as applicable, or by reason of
reckless disregard of obligations and duties hereunder or under the Custodial
Agreement, as applicable.

      (d) The Master Servicer shall not be under any obligation to appear in,
prosecute or defend any legal action that is not incidental to its duties under
this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, the Master Servicer may in its discretion, with
the consent of the Trustee (which consent shall not be unreasonably withheld),
undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the

                                       92
<PAGE>

Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom shall be expenses, costs and
liabilities of the Trust Fund, and the Master Servicer shall be entitled to be
reimbursed therefor out of the Master Servicer Collection Account as provided by
Section 4.03. Nothing in this Subsection 7.04(d) shall affect the Master
Servicer's obligation to supervise, or to take such actions as are necessary to
ensure, the servicing and administration of the Mortgage Loans pursuant to
Subsection 3.01(a).

      (e) In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, the
Master Servicer shall not be required to investigate or make recommendations
concerning potential liabilities which the Trust might incur as a result of such
course of action by reason of the condition of the Mortgaged Properties but
shall give notice to the Trustee if it has notice of such potential liabilities.

      (f) The Master Servicer shall not be liable for any acts or omissions of
Countrywide or National City as Servicers, except as otherwise expressly
provided herein.

      Section 7.05 Master Servicer Not to Resign.

      Except as provided in Section 7.07, the Master Servicer shall not resign
from the obligations and duties hereby imposed on it except upon a determination
that any such duties hereunder are no longer permissible under applicable law
and such impermissibility cannot be cured. Any such determination permitting the
resignation of the Master Servicer shall be evidenced by an Opinion of
Independent Counsel addressed to the Trustee to such effect delivered to the
Trustee. No such resignation by the Master Servicer shall become effective until
the Company or the Trustee or a successor to the Master Servicer reasonably
satisfactory to the Trustee shall have assumed the responsibilities and
obligations of the Master Servicer in accordance with Section 8.02 hereof. The
Trustee shall notify the Rating Agencies of the resignation of the Master
Servicer.

      Section 7.06 Successor Master Servicer.

      In connection with the appointment of any successor master servicer or the
assumption of the duties of the Master Servicer, the Company or the Trustee may
make such arrangements for the compensation of such successor master servicer
out of payments on the Mortgage Loans as the Company or the Trustee and such
successor master servicer shall agree. If the successor master servicer does not
agree that such market value is a fair price, such successor master servicer
shall obtain two quotations of market value from third parties actively engaged
in the servicing of single-family mortgage loans. Notwithstanding the foregoing,
the compensation payable to a successor master servicer may not exceed the
compensation which the Master Servicer would have been entitled to retain if the
Master Servicer had continued to act as Master Servicer hereunder.

      Section 7.07 Sale and Assignment of Master Servicing.

      The Master Servicer may sell and assign its rights and delegate its duties
and obligations in its entirety as Master Servicer under this Agreement and the
Company may terminate the

                                       93
<PAGE>

Master Servicer without cause and select a new Master Servicer; provided,
however, that: (i) the purchaser or transferee accepting such assignment and
delegation (a) shall be a Person which shall be qualified to service mortgage
loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than
$10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause
(ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced
in a writing signed by the Trustee); and (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
from and after the effective date of such agreement; (ii) each Rating Agency
shall be given prior written notice of the identity of the proposed successor to
the Master Servicer and each Rating Agency's rating of the Certificates in
effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer and the Trustee; (iii) the Master Servicer assigning and selling the
master servicing shall deliver to the Trustee an Officer's Certificate and an
Opinion of Independent Counsel addressed to the Trustee, each stating that all
conditions precedent to such action under this Agreement have been completed and
such action is permitted by and complies with the terms of this Agreement; and
(iv) in the event the Master Servicer is terminated without cause by the
Company, the Company shall pay the terminated Master Servicer a termination fee
equal to 0.25% of the aggregate Scheduled Principal Balance of the Mortgage
Loans at the time the master servicing of the Mortgage Loans is transferred to
the successor Master Servicer. No such assignment or delegation shall affect any
liability of the Master Servicer arising prior to the effective date thereof.

                                     Default

      Section 8.01 Events of Default.

      "Event of Default," wherever used herein, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body) and only with respect to the defaulting
Master Servicer:

            (i) The Master Servicer fails to cause to be deposited in the
Distribution Account any amount so required to be deposited pursuant to this
Agreement (other than a Monthly Advance), and such failure continues unremedied
for a period of three Business Days after the date upon which written notice of
such failure, requiring the same to be remedied, shall have been given to the
Master Servicer; or

            (ii) The Master Servicer fails to observe or perform in any material
respect any other material covenants and agreements set forth in this Agreement
to be performed by it, which covenants and agreements materially affect the
rights of Certificateholders, and such failure continues unremedied for a period
of 60 days after the date on which written notice of such failure, properly
requiring the same to be remedied, shall have been given to the Master Servicer
by the Trustee or to the Master Servicer and the Trustee by the Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
25% of the Trust Fund; or

            (iii) There is entered against the Master Servicer a decree or order
by a court or agency or supervisory authority having jurisdiction in the
premises for the appointment of a conservator, receiver or liquidator in any
insolvency, readjustment of debt, marshaling of assets and liabilities or
similar proceedings, or for the winding up or liquidation of its affairs, and
the continuance of any such decree or order is unstayed and in effect for a
period of 60 consecutive days, or an involuntary case is commenced against the
Master Servicer under any applicable insolvency or reorganization statute and
the petition is not dismissed within 60 days after the commencement of the case;
or

            (iv) The Master Servicer consents to the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshaling of assets and liabilities or similar proceedings of or relating to
the Master Servicer or substantially all of its property; or the Master Servicer
admits in writing its inability to pay its debts generally as they become due,
files a petition to take advantage of any applicable insolvency or
reorganization statute, makes an assignment for the benefit of its creditors, or
voluntarily suspends payment of its obligations;

            (v) The Master Servicer assigns or delegates its duties or rights
under this Agreement in contravention of the provisions permitting such
assignment or delegation under Sections 7.05 or 7.07; or

                                       95
<PAGE>

            (vi) The Master Servicer fails to deposit, or cause to be deposited,
in the Distribution Account any Monthly Advance (other than a Nonrecoverable
Advance) by 5:00 p.m. New York City time on the Distribution Account Deposit
Date.

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the principal of the Trust Fund, by notice in writing to
the Master Servicer (and to the Trustee if given by such Certificateholders),
with a copy to the Rating Agencies, and with the consent of the Company, may
terminate all of the rights and obligations (but not the liabilities) of the
Master Servicer under this Agreement and in and to the Mortgage Loans and/or the
REO Property serviced by the Master Servicer and the proceeds thereof. Upon the
receipt by the Master Servicer of the written notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates, the Mortgage Loans, REO Property or under any other related
agreements (but only to the extent that such other agreements relate to the
Mortgage Loans or related REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; and (ii) originals or copies
of all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder. In addition to any
other amounts which are then, or, notwithstanding the termination of its
activities under this Agreement, may become payable to the Master Servicer under
this Agreement, the Master Servicer shall be entitled to receive, out of any
amount received on account of a Mortgage Loan or related REO Property, that
portion of such payments which it would have received as reimbursement under
this Agreement if notice of termination had not been given. The termination of
the rights and obligations of the Master Servicer shall not affect any
obligations incurred by the Master Servicer prior to such termination.

      Notwithstanding the foregoing, if an Event of Default described in clause
(vi) of this Section 8.01 shall occur, the Trustee shall, by notice in writing
to the Master Servicer, which may be delivered by telecopy, immediately
terminate all of the rights and obligations of the Master Servicer thereafter
arising under this Agreement, but without prejudice to any rights it may have as
a Certificateholder or to reimbursement of Monthly Advances and other advances
of its own funds, and the Trustee shall act as provided in Section 8.02 to carry
out the duties of the Master Servicer, including the obligation to make any
Monthly Advance the nonpayment of which was an Event of Default described in
clause (vi) of this Section 8.01. Any such action taken by the Trustee must be
prior to the distribution on the relevant Distribution Date.

      Section 8.02 Trustee to Act; Appointment of Successor.

      (a) Upon the receipt by the Master Servicer of a notice of termination
pursuant to Section 8.01 or an Opinion of Independent Counsel pursuant to
Section 7.05 to the effect that the Master Servicer is legally unable to act or
to delegate its duties to a Person which is legally able to act, the Trustee
shall automatically become the successor in all respects to the Master Servicer
in its capacity under this Agreement and the transactions set forth or provided
for herein and shall thereafter be subject to all the responsibilities, duties,
liabilities and limitations on liabilities relating thereto placed on the Master
Servicer by the terms and provisions hereof; provided, however, that the Company
shall have the right to either (a) immediately assume the duties of the Master
Servicer or (b) select a successor Master Servicer; provided further, however,
that the Trustee shall have no obligation whatsoever with respect to any
liability (other than advances deemed recoverable and not previously made)
incurred by the Master Servicer at or prior to the time of termination. As
compensation therefor, but subject to Section 7.06, the Trustee shall be
entitled to compensation which the Master Servicer would have been entitled to
retain if the Master Servicer had continued to act hereunder, except for those
amounts due the Master Servicer as reimbursement permitted under this Agreement
for advances previously made or expenses previously incurred. Notwithstanding
the above, the Trustee may, if it shall be unwilling so to act, or shall, if it
is legally unable so to act, appoint or petition a court of competent
jurisdiction to appoint, any established housing and home finance institution
which is a Fannie Mae- or Freddie Mac-approved servicer, and with respect to a
successor to the Master Servicer only, having a net worth of not less than
$10,000,000, as the successor to the Master Servicer hereunder in the assumption
of all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder; provided, that the Trustee shall obtain a letter from each
Rating Agency that the ratings, if any, on each of the Certificates will not be
lowered as a result of the selection of the successor to the Master Servicer.
Pending appointment of a successor to the Master Servicer hereunder, the Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on the Mortgage Loans as it and
such successor shall agree; provided, however, that the provisions of Section
7.06 shall apply, the compensation shall not be in excess of that which the
Master Servicer would have been entitled to if the Master Servicer had continued
to act hereunder, and that such successor shall undertake and assume the
obligations of the Trustee to pay compensation to any third Person acting as an
agent or independent contractor in the performance of master servicing
responsibilities hereunder. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

      (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX shall be inapplicable to the Trustee in its duties as the successor
to the Master Servicer in the servicing of the Mortgage Loans (although such
provisions shall continue to apply to the Trustee in its capacity as Trustee);
the provisions of Article VII, however, shall apply to it in its capacity as
successor master servicer.

      Section 8.03 Notification to Certificateholders.

      Upon any termination or appointment of a successor to the Master Servicer,
the Trustee shall give prompt written notice thereof to Certificateholders at
their respective addresses appearing in the Certificate Register and to the
Rating Agencies.

      Section 8.04 Waiver of Defaults.

      The Trustee shall transmit by mail to all Certificateholders, within 60
days after the occurrence of any Event of Default actually known to a
Responsible Officer of the Trustee, unless such Event of Default shall have been
cured, notice of each such Event of Default. The Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 51% of the
Trust Fund may, on behalf of all Certificateholders, waive any default by the
Master Servicer in the performance of its obligations hereunder and the
consequences thereof, except a default in the making of or the causing to be
made any required distribution on the Certificates, which default may only be
waived by Holders of Certificates evidencing Fractional Undivided Interests
aggregating 100% of the Trust Fund. Upon any such waiver of a past default, such
default shall be deemed to cease to exist, and any Event of Default arising
therefrom shall be deemed to have been timely remedied for every purpose of this
Agreement. No such waiver shall extend to any subsequent or other default or
impair any right consequent thereon except to the extent expressly so waived.
The Trustee shall give notice of any such waiver to the Rating Agencies.

      Section 8.05 List of Certificateholders.

      Upon written request of three or more Certificateholders of record, for
purposes of communicating with other Certificateholders with respect to their
rights under this Agreement, the Trustee will afford such Certificateholders
access during business hours to the most recent list of Certificateholders held
by the Trustee.

             Concerning the Trustee and the Securities Administrator

      Section 9.01 Duties of Trustee.

      (a) The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiver of all Events of Default which may have occurred, and the
Securities Administrator each undertake to perform such duties and only such
duties as are specifically set forth in this Agreement as duties of the Trustee
and the Securities Administrator, respectively. If an Event of Default has
occurred and has not been cured or waived, the Trustee shall exercise such of
the rights and powers vested in it by this Agreement, and subject to Section
8.02(b) use the same degree of care and skill in their exercise, as a prudent
person would exercise under the circumstances in the conduct of his own affairs.

      (b) Upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments which are specifically required
to be furnished to the Trustee and the Securities Administrator pursuant to any
provision of this Agreement, the Trustee and the Securities Administrator,
respectively, shall examine them to determine whether they are in the form
required by this Agreement; provided, however, that neither the Trustee nor the
Securities Administrator shall be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished hereunder; provided, further, that neither the Trustee nor
the Securities Administrator shall be responsible for the accuracy or
verification of any calculation provided to it pursuant to this Agreement.

      (c) On each Distribution Date, the Trustee shall make monthly
distributions and the final distribution to the Certificateholders from funds in
the Distribution Account as provided in Sections 6.01 and 10.01 herein based
solely on the report of the Securities Administrator.

      (d) No provision of this Agreement shall be construed to relieve the
Trustee or the Securities Administrator from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct;
provided, however, that:

            (i) Prior to the occurrence of an Event of Default, and after the
curing or waiver of all such Events of Default which may have occurred, the
duties and obligations of the Trustee and the Securities Administrator shall be
determined solely by the express provisions of this Agreement, neither the
Trustee nor the Securities Administrator shall be liable except for the
performance of their respective duties and obligations as are specifically set
forth in this Agreement, no implied covenants or obligations shall be read into
this Agreement against the Trustee or the Securities Administrator and, in the
absence of bad faith on the part of the Trustee or the Securities Administrator,
respectively, the Trustee or the Securities Administrator, respectively, may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon any certificates or opinions furnished to the
Trustee or the Securities Administrator, respectively, and conforming to the
requirements of this Agreement;

            (ii) Neither the Trustee nor the Securities Administrator shall be
liable in its individual capacity for an error of judgment made in good faith by
a Responsible Officer or

                                       99
<PAGE>

Responsible Officers of the Trustee or an officer of the Securities
Administrator, respectively, unless it shall be proved that the Trustee or the
Securities Administrator, respectively, was negligent in ascertaining the
pertinent facts;

            (iii) Neither the Trustee nor the Securities Administrator shall be
liable with respect to any action taken, suffered or omitted to be taken by it
in good faith in accordance with the directions of the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 25% of the
Trust Fund, if such action or non-action relates to the time, method and place
of conducting any proceeding for any remedy available to the Trustee or the
Securities Administrator, respectively, or exercising any trust or other power
conferred upon the Trustee or the Securities Administrator, respectively, under
this Agreement;

            (iv) The Trustee shall not be required to take notice or be deemed
to have notice or knowledge of any default or Event of Default unless a
Responsible Officer of the Trustee's Corporate Trust Office shall have actual
knowledge thereof. In the absence of such notice, the Trustee may conclusively
assume there is no such default or Event of Default;

            (v) The Trustee shall not in any way be liable by reason of any
insufficiency in any Account held by or in the name of Trustee unless it is
determined by a court of competent jurisdiction that the Trustee's gross
negligence or willful misconduct was the primary cause of such insufficiency
(except to the extent that the Trustee is obligor and has defaulted thereon);

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

            (vii) None of the Securities Administrator, the Depositor, the
Company or the Trustee shall be responsible for the acts or omissions of the
other, it being understood that this Agreement shall not be construed to render
them partners, joint venturers or agents of one another and

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

      Section 9.02 Certain Matters Affecting the Trustee and the Securities
Administrator.

      Except as otherwise provided in Section 9.01:

            (i) The Trustee and the Securities Administrator may rely and shall
be protected in acting or refraining from acting in reliance on any resolution,
certificate of the Depositor, the Master Servicer or a Servicer, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

            (ii) The Trustee and the Securities Administrator may consult with
counsel and any advice of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection with respect to any action taken or
suffered or omitted by it hereunder in good faith and in accordance with such
advice or Opinion of Counsel:

            (iii) Neither the Trustee nor the Securities Administrator shall be
under any obligation to exercise any of the trusts or powers vested in it by
this Agreement, other than its obligation to give notices pursuant to this
Agreement, or to institute, conduct or defend any litigation hereunder or in
relation hereto at the request, order or direction of any of the
Certificateholders pursuant to the provisions of this Agreement, unless such
Certificateholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby. Nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default of which a
Responsible Officer of the Trustee has actual knowledge (which has not been
cured or waived), to exercise such of the rights and powers vested in it by this
Agreement, and to use the same degree of care and skill in their exercise, as a
prudent person would exercise under the circumstances in the conduct of his own
affairs;

            (iv) Prior to the occurrence of an Event of Default hereunder and
after the curing or waiver of all Events of Default which may have occurred,
neither the Trustee nor the Securities Administrator shall be liable in its
individual capacity for any action taken, suffered or omitted by it in good
faith and believed by it to be authorized or within the discretion or rights or
powers conferred upon it by this Agreement;

            (v) Neither the Trustee nor the Securities Administrator shall be
bound to make any investigation into the facts or matters stated in any

<PAGE>

instrument, opinion, report, notice, request, consent, order, approval, bond or
other paper or document, unless requested in writing to do so by Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
25% of the Trust Fund and provided that the payment within a reasonable time to
the Trustee or the Securities Administrator, as applicable, of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee or the Securities Administrator,
as applicable, reasonably assured to the Trustee or the Securities
Administrator, as applicable, by the security afforded to it by the terms of
this Agreement. The Trustee or the Securities Administrator may require
reasonable indemnity against such expense or liability as a condition to taking
any such action. The reasonable expense of every such examination shall be paid
by the Certificateholders requesting the investigation;

            (vi) The Trustee and the Securities Administrator may execute any of
the trusts or powers hereunder or perform any duties hereunder either directly
or through Affiliates, agents or attorneys; provided, however, that the Trustee
may not appoint any agent to perform its custodial functions with respect to the
Mortgage Files or paying agent functions under this Agreement without the
express written consent of the Master Servicer, which consent will not be
unreasonably withheld. Neither the Trustee nor the Securities Administrator
shall be liable or responsible for the misconduct or negligence of any of the
Trustee's or the Securities Administrator's agents or attorneys or a custodian
or paying agent appointed hereunder by the Trustee or the Securities
Administrator with due care and, when required, with the consent of the Master
Servicer;

            (vii) Should the Trustee or the Securities Administrator deem the
nature of any action required on its part, other than a payment or transfer
under Subsection 4.01(b) or Section 4.02, to be unclear, the Trustee or the
Securities Administrator, respectively, may require prior to such action that it
be provided by the Depositor with reasonable further instructions;

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

            (ix) Neither the Trustee nor the Securities Administrator shall be
required to give any bond or surety with respect to the execution of the trust
created hereby or the powers granted hereunder, except as provided in Subsection
9.07; and

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

Certificates or Mortgage Loans.

      The recitals contained herein and in the Certificates (other than the
signature and countersignature of the Trustee on the Certificates) shall be
taken as the statements of the Depositor, and neither the Trustee, or the
Custodian on its behalf, nor the Securities Administrator shall have any
responsibility for their correctness. Neither the Trustee nor the Securities
Administrator makes any representation as to the validity or sufficiency of the
Certificates (other than the signature and countersignature of the Trustee on
the Certificates) or of any Mortgage Loan except as expressly provided in
Sections 2.02 and 2.05 hereof; provided, however, that the foregoing shall not
relieve the Trustee, or the Custodian on its behalf, of the obligation to review
the Mortgage Files pursuant to Sections 2.02 and 2.04. The Trustee's signature
and countersignature (or countersignature of its agent) on the Certificates
shall be solely in its capacity as Trustee and shall not constitute the
Certificates an obligation of the Trustee in any other capacity. Neither the
Trustee or the Securities Administrator shall be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor with respect to the Mortgage Loans. Subject to the provisions of
Section 2.05, neither the Trustee nor the Securities Administrator shall be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. Neither the
Trustee nor the Securities Administrator shall at any time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. Neither the Trustee nor the Securities Administrator shall have any
responsibility for filing any financing statement or continuation statement in
any public office at any time or to otherwise perfect or maintain the perfection
of any security interest or lien granted to it hereunder or to record this
Agreement.

      Section 9.04 Trustee and Securities Administrator May Own Certificates.

      The Trustee and the Securities Administrator in its individual capacity or
in any capacity other than as Trustee hereunder may become the owner or pledgee
of any Certificates with the same rights it would have if it were not Trustee or
the Securities Administrator, as applicable, and may otherwise deal with the
parties hereto.

      Section 9.05 Trustee's and Securities Administrator's Fees and Expenses.

      The fees and expenses of the Trustee and the Securities Administrator
shall be paid in accordance with a side letter agreement between the Trustee and
the Master Servicer. In addition, the Trustee and the Securities Administrator
will be entitled to recover from the Master Servicer Collection Account pursuant
to Section 4.03(b) all reasonable out-of-pocket expenses, disbursements and
advances and the expenses of the Trustee and the Securities Administrator,

                                      103
<PAGE>

respectively, in connection with any Event of Default, 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 Trustee or the Securities
Administrator, respectively, in the administration of the trusts hereunder
(including the reasonable compensation, expenses and disbursements of its
counsel) except any such expense, disbursement or advance as may arise from its
negligence or intentional misconduct or which is the responsibility of the
Certificateholders. If funds in the Master Servicer Collection Account are
insufficient therefor, the Trustee and the Securities Administrator shall
recover such expenses from the Depositor and the Depositor hereby agrees to pay
such expenses, disbursements or advances upon demand. 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.

      Section 9.06 Eligibility Requirements for Trustee and Securities
Administrator.

      The Trustee and any successor Trustee and the Securities Administrator and
any successor Securities Administrator shall during the entire duration of this

organized and doing business under the laws of such state or the United States
of America, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus and undivided profits of at least
$40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to
supervision or examination by federal or state authority and, in the case of the
Trustee, rated "BBB" or higher by S&P with respect to their long-term rating and

otherwise acceptable to, each of the Rating Agencies. If the Trustee publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 9.06 the combined capital and surplus of such corporation shall be
deemed to be its total equity capital (combined capital and surplus) as set
forth in its most recent report of condition so published. In case at any time
the Trustee or the Securities Administrator shall cease to be eligible in
accordance with the provisions of this Section 9.06, the Trustee or the
Securities Administrator shall resign immediately in the manner and with the
effect specified in Section 9.08.

      The Trustee and the Securities Administrator, at their own expense, shall
at all times maintain and keep in full force and effect: (i) fidelity insurance,
(ii) theft of documents insurance and (iii) forgery insurance (which may be
collectively satisfied by a "Financial Institution Bond" and/or a "Bankers'
Blanket Bond"). All such insurance shall be in amounts, with standard coverage
and subject to deductibles, as are customary for insurance typically maintained
by banks or their affiliates which act as custodians for investor-owned mortgage
pools. A certificate of an officer of the Trustee or the Securities
Administrator as to the Trustee's or the Securities Administrator's,
respectively, compliance with this Section 9.07 shall be furnished to any
Certificateholder upon reasonable written request.

      (a) The Trustee and the Securities Administrator may at any time resign

Securities Administrator, as applicable, or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or the
Securities Administrator, as applicable, or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then the Depositor shall
promptly remove the Trustee, or shall be entitled to remove the Securities

Administrator so removed and the successor so appointed. In the event that the

responsible for paying any compensation payable to a successor Trustee or
successor Securities Administrator, in excess of the amount paid to the
predecessor Trustee or predecessor Securities Administrator, as applicable.

      (d) No resignation or removal of the Trustee or the Securities

      (a) Any successor Trustee or Securities Administrator appointed as
provided in Section 9.08 shall execute, acknowledge and deliver to the Depositor
and to its predecessor Trustee or Securities Administrator an instrument
accepting such appointment hereunder. The resignation or removal of the
predecessor Trustee or Securities Administrator shall then become effective and
such successor Trustee or Securities Administrator, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with like effect as if

Trustee or Securities Administrator shall after payment of its outstanding fees
and expenses promptly deliver to the successor Trustee or Securities

hereunder, and the Depositor and the predecessor Trustee or Securities
Administrator, as applicable, shall execute and deliver such instruments and do
such other things as may reasonably be required for more fully and certainly
vesting and confirming in the successor Trustee or Securities Administrator, as
applicable, all such rights, powers, duties and obligations.

Administrator as provided in this Section 9.09, the successor Trustee or

Administrator.

      Section 9.10 Merger or Consolidation of Trustee or Securities
Administrator.

      Any state bank or trust company or national banking association into which
the Trustee or the Securities Administrator may be merged or converted or with
which it may be consolidated or any state bank or trust company or national

which the Trustee or the Securities Administrator, respectively, shall be a
party, or any state bank or trust company or national banking association
succeeding to all or substantially all of the corporate trust business of the
Trustee or the Securities Administrator, respectively, shall be the successor of
the Trustee or the Securities Administrator, respectively, hereunder, provided
such state bank or trust company or national banking association shall be
eligible under the provisions of Section 9.06. Such succession shall be valid
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

      Section 9.11 Appointment of Co-Trustee or Separate Trustee.

      (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust or property

                                      106
<PAGE>

constituting the same may at the time be located, the Depositor and the Trustee
acting jointly shall have the power and shall execute and deliver all
instruments to appoint one or more Persons approved by the Trustee and the
Depositor to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity, such title to the Trust, or
any part thereof, and, subject to the other provisions of this Section 9.11,
such powers, duties, obligations, rights and trusts as the Depositor and the
Trustee may consider necessary or desirable.

      (b) If the Depositor shall not have joined in such appointment within 15
days after the receipt by it of a written request so to do, the Trustee shall
have the power to make such appointment without the Depositor.

      (c) No co-trustee or separate trustee hereunder shall be required to meet
the terms of eligibility as a successor Trustee under Section 9.06 hereunder and
no notice to Certificateholders of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 9.08 hereof.

      (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the 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 or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

      (e) Any notice, request or other writing given to the 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 Agreement and the conditions
of this Article IX. 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 Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

      (f) To the extent not prohibited by law, any separate trustee or
co-trustee may, at any time, request the Trustee, its agent or attorney-in-fact,
with full power and authority, to do any lawful act under or with respect to
this 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 Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

                                      107
<PAGE>

      (g) No trustee under this Agreement shall be personally liable by reason
of any act or omission of another trustee under this Agreement. The Depositor
and the Trustee acting jointly may at any time accept the resignation of or
remove any separate trustee or co-trustee.

      Section 9.12 Federal Information Returns and Reports to
Certificateholders; REMIC Administration.

      (a) For federal income tax purposes, the taxable year of each REMIC shall
be a calendar year and the Securities Administrator shall maintain or cause the
maintenance of the books of each such REMIC on the accrual method of accounting.

      (b) The Securities Administrator shall prepare and file or cause to be
filed with the Internal Revenue Service, and the Trustee shall sign, Federal tax
information returns or elections required to be made hereunder with respect to
each REMIC, the Trust Fund, if applicable, and the Certificates containing such
information and at the times and in the manner as may be required by the Code or
applicable Treasury regulations, and shall furnish to each Holder of
Certificates at any time during the calendar year for which such returns or
reports are made such statements or information at the times and in the manner
as may be required thereby, including, without limitation, reports relating to
interest, original issue discount and market discount or premium (using a
constant prepayment assumption of 25% CPR). The Securities Administrator will
apply for an Employee Identification Number from the IRS under Form SS-4 or any
other acceptable method for all tax entities. In connection with the foregoing,
the Securities Administrator shall timely prepare and file, and the Trustee
shall sign, IRS Form 8811, which shall provide the name and address of the
person who can be contacted to obtain information required to be reported to the
holders of regular interests in each REMIC (the "REMIC Reporting Agent"). The
Trustee shall make elections to treat each REMIC as a REMIC (which elections
shall apply to the taxable period ending December 31, 2004 and each calendar
year thereafter) in such manner as the Code or applicable Treasury regulations
may prescribe, and as described by the Securities Administrator. The Trustee
shall sign all tax information returns filed pursuant to this Section and any
other returns as may be required by the Code. The Holder of the Class R-I
Certificate is hereby designated as the "Tax Matters Person" (within the meaning
of Treas. Reg. ss.ss.1.860F-4(d)) for REMIC I, the Holder of the Class R-II
Certificate is hereby designated as the "Tax Matters Person" for REMIC II and
the Holder of the Class R-III Certificate is hereby designated as the "Tax
Matters Person" for REMIC III. The Securities Administrator is hereby designated
and appointed as the agent of each such Tax Matters Person. Any Holder of a
Residual Certificate will by acceptance thereof appoint the Securities
Administrator as agent and attorney-in-fact for the purpose of acting as Tax
Matters Person for each REMIC during such time as the Securities Administrator
does not own any such Residual Certificate. In the event that the Code or
applicable Treasury regulations prohibit the Trustee from signing tax or
information returns or other statements, or the Securities Administrator from
acting as agent for the Tax Matters Person, the Trustee and the Securities
Administrator shall take whatever action that in its sole good faith judgment is
necessary for the proper filing of such information returns or for the provision
of a tax matters person, including designation of the Holder of a Residual
Certificate to sign such returns or act as tax matters person. Each Holder of a
Residual Certificate shall be bound by this Section.

                                      108
<PAGE>

      (c) The Securities Administrator shall provide upon request and receipt of
reasonable compensation, such information as required in Section 860D(a)(6)(B)
of the Code to the Internal Revenue Service, to any Person purporting to
transfer a Residual Certificate to a Person other than a transferee permitted by
Section 5.05(b), and to any regulated investment company, real estate investment
trust, common trust fund, partnership, trust, estate, organization described in
Section 1381 of the Code, or nominee holding an interest in a pass-through
entity described in Section 860E(e)(6) of the Code, any record holder of which
is not a transferee permitted by Section 5.05(b) (or which is deemed by statute
to be an entity with a disqualified member).

      (d) The Securities Administrator shall prepare and file or cause to be
filed, and the Trustee shall sign, any state income tax returns required under
Applicable State Law with respect to each REMIC or the Trust Fund.

      (e) Notwithstanding any other provision of this Agreement, the Trustee and
the Securities Administrator shall comply with all federal withholding
requirements respecting payments to Certificateholders of interest or original
issue discount on the Mortgage Loans, that the Trustee or the Securities
Administrator reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee or the Securities Administrator withholds any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trustee or the Securities
Administrator shall, together with its monthly report to such
Certificateholders, indicate such amount withheld.

      (f) The Trustee and the Securities Administrator agree to indemnify the
Trust Fund and the Depositor for any taxes and costs including, without
limitation, any reasonable attorneys fees imposed on or incurred by the Trust
Fund, the Depositor or the Master Servicer, as a result of a breach of the
Trustee's covenants and the Securities Administrator's covenants, respectively,
set forth in this Section 9.12; provided, however, such liability and obligation
to indemnify in this paragraph shall not be joint and several and neither the
Trustee nor the Securities Administrator shall be liable or be obligated to
indemnify the Trust Fund for the failure by the other to perform any duty under
this Agreement or the breach by the other of any covenant in this Agreement.

the sum of (a) 100% of the Outstanding Principal Balance of each Mortgage Loan
(other than a Mortgage Loan related to REO Property) as of the date of
repurchase, net of the principal portion of any unreimbursed Monthly Advances
made by the purchaser, together with interest at the applicable Mortgage
Interest Rate accrued but unpaid to, but not including, the first day of the
month of repurchase, (b) the appraised value of any related REO Property, less
the good faith estimate of the Depositor of liquidation expenses to be incurred
in connection with its disposal thereof (but not more than the Outstanding
Principal Balance of the related Mortgage Loan, together with interest at the
applicable Mortgage Interest Rate accrued on that balance but unpaid to, but not
including, the first day of the month of repurchase), such appraisal to be
calculated by an appraiser mutually agreed upon by the Depositor and the Trustee
at the expense of the Depositor, (c) unreimbursed out-of pocket costs of the
Master Servicer, including unreimbursed servicing advances and the principal
portion of any unreimbursed Monthly Advances, made on the Mortgage Loans prior
to the exercise of such repurchase right and (d) any unreimbursed costs and
expenses of the Trustee and the Securities Administrator payable pursuant to
Section 9.05; or

            (ii) the later of the making of the final payment or other
liquidation, or any advance with respect thereto, of the last Mortgage Loan
remaining in the Trust Fund or the disposition of all property acquired with
respect to any Mortgage Loan; provided, however, that in the event that an
advance has been made, but not yet recovered, at the time of such termination,
the Person having made such advance shall be entitled to receive,
notwithstanding such termination, any payments received subsequent thereto with
respect to which such advance was made; or

            (iii) the payment to the Certificateholders of all amounts required
to be paid to them pursuant to this Agreement.

      (b) In no event, however, shall the Trust created hereby continue beyond
the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James's, living on the date of this Agreement.

      (c) The right of the Depositor or its designee to repurchase all the
assets of the Trust Fund as described in Subsection 10.01(a)(i) above shall be
exercisable only if (i) the aggregate Scheduled Principal Balance of the
Mortgage Loans at the time of any such repurchase is less than 10% of the
Cut-Off Date Balance, or (ii) the Depositor, based upon an Opinion of Counsel
addressed to the Depositor, the Trustee and the Securities Administrator, has
determined that the REMIC status of REMIC I, REMIC II or REMIC III has been lost
or that a substantial risk exists that such REMIC status will be lost for the
then-current taxable year. At any time thereafter, in the case of (i) or (ii)
above, the Depositor may elect to terminate REMIC I, REMIC II and REMIC III at
any time, and upon such election, the Depositor or its designee, shall
repurchase all the assets of the Trust Fund described in Subsection 10.01(a)(i)
above.

      (d) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Master Servicer, the Securities
Administrator and the Rating Agencies, upon which the Certificateholders shall
surrender their Certificates to the Trustee for payment of the final
distribution and cancellation. Such notice shall be given by letter, mailed not
earlier than the l5th day and not later than the 25th day of the month next
preceding the month of such final distribution, and shall specify (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of the Certificates at the office of the Trustee
therein designated, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Trustee therein specified.

      (e) If the option of the Depositor to repurchase or cause the repurchase
of all the assets in the Trust Fund as described in Subsection 10.01(a)(i)
above, is exercised, the Depositor and/or its designee shall deliver to the
Trustee for deposit in the Distribution Account, by the Business Day prior to
the applicable Distribution Date, an amount equal to the Termination Purchase
Price. Upon presentation and surrender of the Certificates by the
Certificateholders, the Trustee shall distribute to such Certificateholders as
directed by the Securities Administrator in writing an amount determined as
follows: with respect to each Certificate (other than the Interest Only
Certificates and the Class R Certificates), the outstanding Current Principal
Amount, plus with respect to each Certificate (other than the Class R
Certificates), one month's interest thereon at the applicable Pass-Through Rate;
and with respect to the Class R Certificates, the percentage interest evidenced
thereby multiplied by the difference, if any, between the above described
repurchase price and the aggregate amount to be distributed to the Holders of
the Certificates in such Certificate Group (other than the Class R
Certificates). If the proceeds with respect to the Mortgage Loans of a Loan
Group are not sufficient to pay all of the Senior Certificates of the related
Certificate Group in full, any such deficiency shall be allocated first, to the
Subordinate Certificates, in inverse order of their numerical designation and
then to the Senior Certificates of the related Certificate Group on a pro rata
basis. Upon deposit of the Termination Purchase Price and following such final
Distribution Date, the Trustee shall release promptly to the Depositor and/or
its designee the Mortgage Files for the remaining Mortgage Loans, and the
Accounts with respect thereto shall terminate, subject to the Trustee's
obligation to hold any amounts payable to the Certificateholders in trust
without interest pending final distributions pursuant to Subsection 10.01(g).
Any other amounts remaining in the Accounts will belong to the Depositor.

                                      111
<PAGE>

      (f) In the event that this Agreement is terminated by reason of the
payment or liquidation of all Mortgage Loans or the disposition of all property
acquired with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above,
the Master Servicer shall deliver to the Trustee for deposit in the Distribution
Account all distributable amounts remaining in the Master Servicer Collection
Account. Upon the presentation and surrender of the Certificates, the Trustee
shall distribute to the remaining Certificateholders, pursuant to the written
direction of the Securities Administrator and in accordance with their
respective interests, all distributable amounts remaining in the Distribution
Account. Upon deposit by the Master Servicer of such distributable amounts, and
following such final Distribution Date, the Trustee shall release promptly to
the Depositor or its designee the Mortgage Files for the remaining Mortgage
Loans, and the Master Servicer Collection Account and the Distribution Account
shall terminate, subject to the Trustee's obligation to hold any amounts payable
to the Certificateholders in trust without interest pending final distributions
pursuant to this Subsection 10.01(f).

      (g) If not all of the Certificateholders shall surrender their
Certificates for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

      Section 10.02 Additional Termination Requirements.

      (a) If the option of the Depositor to repurchase all of the Mortgage Loans
under Subsection 10.01(a)(i) above is exercised, the Trust Fund and each REMIC
shall be terminated in accordance with the following additional requirements,
unless the Trustee has been furnished with an Opinion of Counsel addressed to
the Trustee to the effect that the failure of the Trust to comply with the
requirements of this Section 10.02 will not (i) result in the imposition of
taxes on "prohibited transactions" as defined in Section 860F of the Code on any
REMIC or (ii) cause any REMIC to fail to qualify as a REMIC at any time that any
Regular Certificates are outstanding:

            (i) within 90 days prior to the final Distribution Date, at the
written direction of the Depositor, the Trustee, as agent for the respective Tax
Matters Persons, shall adopt a plan of complete liquidation of each REMIC in the
case of a termination under Subsection 10.01(a)(i), provided to it by the
Depositor, which meets the requirements of a "qualified liquidation" under
Section 860F of the Code and any regulations thereunder;

            (ii) the Depositor shall notify the Trustee at the commencement of
such 90-day liquidation period and, at or prior to the time of making of the
final payment on the Certificates, the Trustee shall sell or otherwise dispose
of all of the remaining assets of the Trust Fund in accordance with the terms
hereof; and

                                      112
<PAGE>

            (iii) at or after the time of adoption of such a plan of complete
liquidation of each REMIC, and at or prior to the final Distribution Date
relating thereto, the Trustee shall sell for cash all of the assets of the Trust
to or at the direction of the Depositor, and each REMIC shall terminate at such
time.

      (b) By their acceptance of the Residual Certificates, the Holders thereof
hereby (i) agree to adopt such a plan of complete liquidation of the related
REMIC upon the written request of the Depositor, and to take such action in
connection therewith as may be reasonably requested by the Depositor and (ii)
appoint the Depositor as their attorney-in-fact, with full power of
substitution, for purposes of adopting such a plan of complete liquidation. The
Trustee shall adopt such plan of liquidation by filing the appropriate statement
on the final tax return of each REMIC. Upon complete liquidation or final
distribution of all of the assets of the Trust Fund, the Trust Fund and each
REMIC shall terminate.

                            Miscellaneous Provisions

      Section 11.01 Intent of Parties.

      The parties intend that each of REMIC I, REMIC II and REMIC III shall be
treated as a REMIC for federal income tax purposes and that the provisions of
this Agreement should be construed in furtherance of this intent.

      Section 11.02 Amendment.

      (a) This Agreement may be amended from time to time by the Company, the
Depositor, the Master Servicer, the Securities Administrator and the Trustee,
without notice to or the consent of any of the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions herein or therein that may be
defective or inconsistent with any other provisions herein or therein, to comply
with any changes in the Code or to make any other provisions with respect to
matters or questions arising under this Agreement which shall not be
inconsistent with the provisions of this Agreement; provided, however, that such
action shall not, as evidenced by an Opinion of Independent Counsel, addressed
to the Trustee, adversely affect in any material respect the interests of any
Certificateholder.

      (b) This Agreement may also be amended from time to time by the Company,
the Master Servicer, the Depositor, the Securities Administrator and the
Trustee, with the consent of the Holders of Certificates evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund or of the
applicable Class or Classes, if such amendment affects only such Class or
Classes, for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Certificateholders; provided, however, that no such
amendment shall (i) reduce in any manner the amount of, or delay the timing of,
payments received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, (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
Certificates then outstanding, or (iii) cause any REMIC to fail to qualify as a
REMIC for federal income tax purposes, as evidenced by an Opinion of Independent
Counsel addressed to the Trustee which shall be provided to the Trustee other
than at the Trustee's expense. Notwithstanding any other provision of this
Agreement, for purposes of the giving or withholding of consents pursuant to
this Section 11.02(b), Certificates registered in the name of or held for the
benefit of the Depositor, the Securities Administrator, the Master Servicer, or
the Trustee or any Affiliate thereof shall be entitled to vote their Fractional
Undivided Interests with respect to matters affecting such Certificates.

      (c) Promptly after the execution of any such amendment, the Trustee shall
furnish a copy of such amendment or written notification of the substance of
such amendment to each Certificateholder, with a copy to the Rating Agencies.

                                      114
<PAGE>

      (d) In the case of an amendment under Subsection 11.02(b) above, it shall
not be necessary for the Certificateholders to approve the particular form of
such an amendment. Rather, it shall be sufficient if the Certificateholders
approve the substance of the amendment. The manner of obtaining such consents
and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable regulations as the
Trustee may prescribe.

      (e) Prior to the execution of any amendment to this Agreement, the Trustee
shall be entitled to receive and rely upon an Opinion of Counsel addressed to
the Trustee stating that the execution of such amendment is authorized or
permitted by this Agreement. The Trustee and the Securities Administrator may,
but shall not be obligated to, enter into any such amendment which affects the
Trustee's or the Securities Administrator's own respective rights, duties or
immunities under this Agreement.

      Section 11.03 Recordation of Agreement.

      To the extent permitted by applicable law, this Agreement is subject to
recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the
Mortgaged Properties are situated, and in any other appropriate public recording
office or elsewhere. The Depositor shall effect such recordation, at the expense
of the Trust upon the request in writing of a Certificateholder, but only if
such direction is accompanied by an Opinion of Counsel (provided at the expense
of the Certificateholder requesting recordation) to the effect that such
recordation would materially and beneficially affect the interests of the
Certificateholders or is required by law.

      Section 11.04 Limitation on Rights of Certificateholders.

      (a) The death or incapacity of any Certificateholder shall not terminate
this Agreement or the Trust, nor 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 the Trust, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

      (b) Except as expressly provided in this Agreement, no Certificateholders
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, or the obligations of the parties hereto, nor shall
anything herein set forth, or contained in the terms of the Certificates, be
construed so as to establish the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholders be under
any liability to any third Person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

      (c) No Certificateholder shall have any right by virtue of any provision
of this Agreement to institute any suit, action or proceeding in equity or at
law upon, under or with respect to this Agreement against the Depositor, the
Securities Administrator, the Master Servicer or any successor to any such
parties unless (i) such Certificateholder previously shall have given to the
Trustee a written notice of a continuing default, as herein provided, (ii) the

                                      115
<PAGE>

Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs and expenses and liabilities to be incurred
therein or thereby, and (iii) the Trustee, for 60 days after its receipt of such
notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding.

      (d) No one or more Certificateholders shall have any right by virtue of
any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain priority or preference over
any other such Certificateholder, or to enforce any right under this Agreement,
except in the manner herein provided and for the equal, ratable and common
benefit of all Certificateholders. For the protection and enforcement of the
provisions of this Section 11.04, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

      Section 11.05 Acts of Certificateholders.

      (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Agreement to be given or taken by
Certificateholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Certificateholders in person or by
an agent duly appointed in writing. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is expressly required, to the
Depositor. Proof of execution of any such instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Agreement and
conclusive in favor of the Trustee and the Depositor, if made in the manner
provided in this Section 11.05.

      (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the individual executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

      (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and neither the
Trustee, the Securities Administrator, the Depositor, the Master Servicer nor
any successor to any such parties shall be affected by any notice to the
contrary.

      (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action of the holder of any Certificate shall bind every future holder
of the same Certificate and

                                      116
<PAGE>

the holder of every Certificate issued upon the registration of transfer or
exchange thereof, if applicable, or in lieu thereof with respect to anything
done, omitted or suffered to be done by the Trustee, the Securities
Administrator, the Depositor, the Master Servicer or any successor to any such
party in reliance thereon, whether or not notation of such action is made upon
such Certificates.

      (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Securities Administrator, the Depositor,
the Master Servicer or any Affiliate thereof shall be disregarded, except as
otherwise provided in Section 11.02(b) and except that, in determining whether
the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only Certificates which a
Responsible Officer of the Trustee actually knows to be so owned shall be so
disregarded. Certificates which have been pledged in good faith to the Trustee,
the Securities Administrator, the Depositor, the Master Servicer or any
Affiliate thereof may be regarded as outstanding if the pledgor establishes to
the satisfaction of the Trustee the pledgor's right to act with respect to such
Certificates and that the pledgor is not an Affiliate of the Trustee, the
Securities Administrator, the Depositor, or the Master Servicer, as the case may
be.

      Section 11.06 Governing Law.

      THIS AGREEMENT AND THE CERTIFICATES SHALL BE CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO ITS CONFLICT OF LAWS

                                  SERIES 2004-7

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [_-[A][X]-_] Certificates with respect to a
         Trust Fund consisting primarily of a pool of adjustable rate mortgage
         loans secured by first liens on one-to-four family residential
         properties sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments II Inc., the Master Servicer or the Trustee referred
to below or any of their affiliates or any other person. Neither this
Certificate nor the underlying Mortgage Loans are guaranteed or insured by any
governmental entity or by Structured Asset Mortgage Investments II Inc., the
Master Servicer or the Trustee or any of their affiliates or any other person.
None of Structured Asset Mortgage Investments II Inc., the Master Servicer or
any of their affiliates will have any obligation with respect to any certificate
or other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Fractional Undivided Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust Fund") primarily consisting of adjustable rate mortgage loans secured by
first liens on one- to four- family residential properties (collectively, the
"Mortgage Loans") sold by Structured Asset Mortgage Investments II Inc. ("SAMI
II"). The

                                      A-1-2
<PAGE>

Mortgage Loans were sold by EMC Mortgage Corporation ("EMC") to SAMI II. Wells
Fargo Bank, National Association ("Wells Fargo") will act as master servicer of
the Mortgage Loans (the "Master Servicer", which term includes any successors
thereto under the Agreement referred to below). The Trust Fund was created
pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement"), among EMC Mortgage Corporation, as seller and
company (the "Seller"), SAMI II, as depositor (the "Depositor"), Wells Fargo
Bank, National Association as master servicer and securities administrator (in
such capacity, the "Securities Administrator") and U.S. Bank National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the [Current Principal][Notional] Amount hereof at a per annum rate equal to
the Pass-Through Rate set forth above and as further described in the Agreement.
The Trustee will distribute on the 25th day of each month, or, if such 25th day
is not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last Business Day of the calendar month preceding the month of
such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount (of interest
[and principal], if any) required to be distributed to the Holders of
Certificates of the same Class as this Certificate. The Assumed Final
Distribution Date is the Distribution Date in the month immediately following
the month of the latest scheduled maturity date of any Mortgage Loan and is not
likely to be the date on which the [Current Principal][Notional] Amount of this
Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement by wire
transfer. Notwithstanding the above, the final distribution on this Certificate
will be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
office or agency appointed by the Trustee for that purpose and designated in
such notice. The Initial [Current Principal][Notional] Amount of this
Certificate is set forth above. [The Current Principal Amount hereof will be
reduced to the extent of distributions allocable to principal hereon and any
Realized Losses allocable hereto.]

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
the Trustee is not liable to the

                                      A-1-3

<PAGE>

Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer and the Trustee and the rights
of the Certificateholders under the Agreement from time to time by the parties
thereto with the consent of the Holders of Certificates, evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund (or in
certain cases, Holders of Certificates of affected Classes evidencing such
percentage of the Fractional Undivided Interests thereof). Any such consent by
the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Master Servicer, the Trustee and any agent of any
of them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional

                                      A-1-4

<PAGE>

repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                  IN WITNESS WHEREOF, the Trustee has caused this Certificate to
be duly executed.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [B-_] Certificates with respect to a Trust Fund
         consisting primarily of a pool of adjustable rate mortgage loans
         secured by first liens on one-to-four family residential properties
         sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments II Inc., the Master Servicer or the Trustee referred
to below or any of their affiliates or any other person. Neither this
Certificate nor the underlying Mortgage Loans are guaranteed or insured by any
governmental entity or by Structured Asset Mortgage Investments II Inc., the
Master Servicer or the Trustee or any of their affiliates or any other person.
None of Structured Asset Mortgage Investments II Inc., the Master Servicer or
any of their affiliates will have any obligation with respect to any certificate
or other obligation secured by or payable from payments on the Certificates.

                  This certifies that [_______] is the registered owner of the
Fractional Undivided Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust Fund") primarily consisting of adjustable rate mortgage loans secured by
first liens on one- to four- family residential properties (collectively, the
"Mortgage Loans") sold by Structured Asset Mortgage Investments II Inc. ("SAMI
II"). The Mortgage Loans were sold by EMC Mortgage Corporation ("EMC") to SAMI
II. Wells Fargo

                                     A-2-4
<PAGE>
Bank, National Association ("Wells Fargo") will act as master servicer of the
Mortgage Loans (the "Master Servicer", which term includes any successors
thereto under the Agreement referred to below). The Trust Fund was created
pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement"), among EMC as seller and company (the
"Seller"), SAMI II, as depositor (the "Depositor"), Wells Fargo Bank, National
Association as master servicer and securities administrator (in such capacity,
the "Securities Administrator") and U.S. Bank National Association, as trustee
(the "Trustee"), a summary of certain of the pertinent provisions of which is
set forth hereafter. To the extent not defined herein, capitalized terms used
herein shall have the meaning ascribed to them in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of its acceptance hereof assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above and as further described in the Agreement. The
Trustee will distribute on the 25th day of each month, or, if such 25th day is
not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last Business Day of the calendar month preceding the month of
such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month immediately following the month of the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Current Principal Amount of this Class of Certificates will be reduced
to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement by wire
transfer. Notwithstanding the above, the final distribution on this Certificate
will be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
office or agency appointed by the Trustee for that purpose and designated in
such notice. The Initial Current Principal Amount of this Certificate is set
forth above. The Current Principal Amount hereof will be reduced to the extent
of distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  [For Class B-4, Class B-5 and Class][No transfer of this Class
[B-_] Certificate will be made unless such transfer is (i) exempt from the
registration requirements of the Securities act of 1933, as amended, and any
applicable state securities laws or is made in accordance with said Act and laws
and (ii) made in accordance with Section 5.02 of the Agreement. In the event
that such transfer is to be made the Trustee shall register such transfer if,
(i) made to a transferee who has provided the Trustee with evidence as to its
QIB status; or (ii) (A) the transferor has advised the Trustee in writing that
the Certificate is being transferred to an Institutional Accredited Investor and
(B) prior to such transfer the transferee furnishes to the Trustee an Investment
Letter; provided that if based upon an Opinion of Counsel to the effect

                                     A-2-5
<PAGE>
that (A) and (B) above are not sufficient to confirm that such transfer is being
made pursuant to an exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act and other applicable laws, the
Trustee shall as a condition of the registration of any such transfer require
the transferor to furnish such other certifications, legal opinions or other
information prior to registering the transfer of this Certificate as shall be
set forth in such Opinion of Counsel.]

                  [For Class B-1, Class B-2 and Class B-3] [Each beneficial
owner of this Certificate or any interest herein shall be deemed to have
represented, by virtue of its acquisition or holding of this certificate or
interest herein, that either (i) it is not an employee benefit plan subject to
the Employee Retirement Income Security Act of 1974, as amended or section 4975
of the Internal Revenue Code of 1986, as amended ("Plan"), or investing with
assets of a Plan or (ii) it has acquired and is holding such certificate in
reliance on Prohibited Transaction Exemption 90-30, as amended from time to time
("Exemption"), and that it understands that there are certain conditions to the
availability of the Exemption, including that the certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by Standard &
Poor's, Fitch, Inc. or Moody's Investors Service, Inc., and the certificate is
so rated or (iii) (1) it is an insurance company, (2) the source of funds used
to acquire or hold the certificate or interest therein is an "insurance company
general account", as such term is defined in Prohibited Transaction Class
Exemption ("PTCE") 95-60, and (3) the conditions in Sections I and III of PTCE
95-60 have been satisfied.]

         [For Class B-4, Class B-5 and Class B-6] [This Certificate may not be
acquired directly or indirectly by, or on behalf of, an employee benefit plan or
other retirement arrangement which is subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended, or Section 4975 of the
Internal Revenue Code of 1986, as amended, unless the transferee certifies or
represents that the proposed transfer and holding of a Certificate and the
servicing, management and operation of the trust and its assets: (i) will not
result in any prohibited transaction which is not covered under an individual or
class prohibited transaction exemption, including, but not limited to,
Prohibited Transaction Exemption ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE 95-60
or PTE 96-23 and (ii) will not give rise to any additional obligations on the
part of the Depositor, the Securities Administrator, the Master Servicer or the
Trustee, which will be deemed represented by an owner of a Book-Entry
Certificate or a Global Certificate or unless the opinion specified in section
5.07 of the Agreement is provided.]

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
the Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in the
Agreement, subject to any liability under the Agreement.

<PAGE>
                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer and the Trustee and the rights
of the Certificateholders under the Agreement from time to time by the parties
thereto with the consent of the Holders of Certificates, evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund (or in
certain cases, Holders of Certificates of affected Classes evidencing such
percentage of the Fractional Undivided Interests thereof). Any such consent by
the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Master Servicer, the Trustee and any agent of any
of them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding

                                     A-2-7
<PAGE>

Principal Balance specified in the Agreement of the Mortgage Loans at the
Cut-off Date. The exercise of such right will effect the early retirement of the
Certificates. In no event, however, will the Trust Fund created by the Agreement
continue beyond the expiration of 21 years after the death of certain persons
identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                        MORTGAGE PASS-THROUGH CERTIFICATE
                                  SERIES 2004-7

         evidencing a fractional undivided interest in the distributions
         allocable to the Class R-[_] Certificates with respect to a Trust Fund
         consisting primarily of a pool of adjustable rate mortgage loans
         secured by first liens on one-to-four family residential properties
         sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments II Inc., the Master Servicer or the Trustee referred
to below or any of their affiliates or any other person. Neither this
Certificate nor the underlying Mortgage Loans are guaranteed or insured by any
governmental entity or by Structured Asset Mortgage Investments II Inc., the
Master Servicer or the Trustee or any of their affiliates or any other person.
None of Structured Asset Mortgage Investments II Inc., the Master Servicer or
any of their affiliates will have any obligation with respect to any certificate
or other obligation secured by or payable from payments on the Certificates.

                  This certifies that Bear, Stearns Securities Corp. is the
registered owner of the Fractional Undivided Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") primarily consisting of adjustable
rate mortgages loans secured by first liens on one- to four- family residential
properties (collectively, the "Mortgage Loans") sold by Structured Asset
Mortgage Investments II Inc. ("SAMI II"). The Mortgage Loans were sold by EMC
Mortgage Corporation ("EMC") to SAMI II. Wells Fargo Bank, National Association
("Wells Fargo") will act as master servicer of

                                      A-3-3

<PAGE>

the Mortgage Loans (the "Master Servicer", which term includes any successors
thereto under the Agreement referred to below). The Trust Fund was created
pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement'), among EMC Mortgage Corporation as seller and
company (the "Seller"), SAMI II, as depositor(the "Depositor"), Wells Fargo
Bank, National Association as master servicer and securities administrator (in
such capacity, the "Securities Administrator") and U.S. Bank National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  The Trustee will distribute on the 25th day of each month, or,
if such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount (of
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month immediately following the month of the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Current Principal Amount of this Class of Certificates will be reduced
to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register, or if such Person so requests
by notifying the Trustee in writing as specified in the Agreement by wire
transfer. Notwithstanding the above, the final distribution on this Certificate
will be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
office or agency appointed by the Trustee for that purpose and designated in
such notice. The Initial Current Principal Amount of this Certificate is set
forth above. The Current Principal Amount hereof will be reduced to the extent
of distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to SAMI II, the Trustee and the Securities Administrator of, among other things,
an affidavit to the effect that it is a United States Person and Permitted
Transferee, (iii) any attempted or purported transfer of any Ownership Interest
in this Certificate in violation of such restrictions will be absolutely null
and void and will vest no rights in the purported transferee, and (iv) if any
person other than a United States Person and a Permitted Transferee acquires any
Ownership Interest in this Certificate in violation of such restrictions, then
the Depositor will have the right, in its sole discretion and without notice to
the Holder of this Certificate, to sell this Certificate to a purchaser selected
by the Depositor, which purchaser may be the Depositor, or any affiliate of the
Depositor, on such terms and conditions as the Depositor may choose.

                  This certificate may not be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to title I of the Employee Retirement Income Security Act of
1974, as amended, and/or section 4975 of the Internal Revenue Code of 1986, as
amended, unless the proposed transferee provides the Trustee with an opinion of
counsel addressed to the Trustee, the Depositor, Master Servicer and the
Securities Administrator and on which they may rely (which shall not be at the
expense of the Trustee, the Depositor, the Master Servicer or the Securities
Administrator) which is acceptable to the Trustee, that the purchase of this
Certificate will not result in or constitute a nonexempt prohibited transaction,
is permissible under applicable law and will not give rise to any additional
fiduciary obligations on the part of the Depositor, the Master Servicer or the
Trustee.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
the Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in the
Agreement, subject to any liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer and the Trustee and the rights
of the Certificateholders under the Agreement from time to time by the parties
thereto with the consent of the Holders of Certificates, evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund (or in
certain cases, Holders of Certificates of affected Classes evidencing such
percentage of the Fractional Undivided Interests thereof). Any such consent by
the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more

                                      A-3-5

<PAGE>
new Certificates evidencing the same Class and in the same aggregate Fractional
Undivided Interest, as requested by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Master Servicer, the Trustee and any agent of any
of them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

Dear Ladies and Gentlemen:

         In connection with our purchase of Privately Offered Certificates, we

                           are not being registered under the Securities Act of
                           1933, as amended (the "Act") or any applicable state
                           securities or "Blue Sky" laws, and are being sold to
                           us in a transaction that is exempt from the

                           Certificates, the trust in which the Certificates
                           represent the entire beneficial ownership interest

                           held indefinitely by us (and may not be sold,
                           pledged, hypothecated or in any way disposed of)

                           Privately Offered Certificates (such disposition or
                           exchange not being currently foreseen or
                           contemplated), we will not transfer or exchange any

                                    (B) if the Privately Offered Certificate is
                           not registered under the Act (as to which we
                           acknowledge you have no obligation), the Privately
                           Offered Certificate is sold in a transaction that
                           does not require registration under the Act and any

                           if U.S. Bank National Association(the "Trustee") so
                           requests, a satisfactory Opinion of Counsel is

                           Offered Certificate directly or indirectly by, or on

                    (b) Within 90 days of the Closing Date, the Custodian
               agrees, for the benefit of Certificateholders, to review, in
               accordance with the provisions of Section 2.02 of the Pooling and

               duty or obligation to inspect, review or examine said documents,
               instruments, certificates or other papers to determine that the
               same are genuine, enforceable, or appropriate for the represented
               purpose or that they have actually been recorded or that they are
               other than what they purport to be on their face.

                    (c) Not later than 180 days after the Closing Date, the
               Custodian shall review the Mortgage Files as provided in Section

                    (d) In reviewing the Mortgage Files as provided herein and
               in the Pooling and Servicing Agreement, the Custodian shall make
               no representation as to and shall not be responsible to verify
               (i) the validity, legality, enforceability, due authorization,
               recordability, sufficiency or genuineness of any of the documents
               included in any Mortgage File or (ii) the collectibility,
               insurability, effectiveness or suitability of any of the
               documents in any Mortgage File.

                                      G-2
<PAGE>

         Upon receipt of written request from the Trustee, the Custodian shall
as soon as practicable supply the Trustee with a list of all of the documents
relating to the Mortgage Loans missing from the Mortgage Files.

         Section 2.4. NOTIFICATION OF BREACHES OF REPRESENTATIONS AND
WARRANTIES. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Depositor as set forth in the Pooling and Servicing
Agreement with respect to a Mortgage Loan relating to a Mortgage File, the
Custodian shall give prompt written notice to the Depositor, the related
Servicer and the Trustee.

         Section 2.5. CUSTODIAN TO COOPERATE: RELEASE OF MORTGAGE FILES. Upon
receipt of written notice from the Trustee that the Seller has repurchased a
Mortgage Loan pursuant to Article II of the Pooling and Servicing Agreement, and
that the purchase price therefore has been deposited in the Master Servicer
Collection Account or the Distribution Account, then the Custodian agrees to
promptly release to the Seller the related Mortgage File.

         Upon the Custodian's receipt of a request for release (a "Request for
Release") substantially in the form of Exhibit D to the Pooling and Servicing
Agreement signed by a Servicing Officer of the related Servicer stating that it
has received payment in full of a Mortgage Loan or that payment in full will be
escrowed in a manner customary for such purposes, the Custodian agrees promptly
to release to the related Servicer the related Mortgage File. The Depositor
shall deliver to the Custodian and the Custodian agrees to accept the Mortgage
Note and other documents constituting the Mortgage File with respect to any
Substitute Mortgage Loan.

         From time to time as is appropriate for the servicing or foreclosure of
any Mortgage Loan, including, for this purpose, collection under any Primary
Insurance Policy, the related Servicer (or if the Servicer does not, the Master
Servicer) shall deliver to the Custodian a Request for Release signed by a
Servicing Officer requesting that possession of all of the Mortgage File be
released to the related Servicer and certifying as to the reason for such
release and that such release will not invalidate any insurance coverage
provided in respect of the Mortgage Loan under any of the Insurance Policies.
Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File to
the related Servicer. The related Servicer shall cause each Mortgage File or any
document therein so released to be returned to the Custodian when the need
therefore by the related Servicer no longer exists, unless (i) the Mortgage Loan
has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan
have been deposited in the Master Servicer Collection Account or the
Distribution Account or (ii) the Mortgage File or such document has been
delivered to an attorney, or to a public trustee or other public official as
required by law, for purposes of initiating or pursuing legal action or other
proceedings for the foreclosure of the Mortgaged Property either judicially or
non-judicially, and the related Servicer has delivered to the Custodian a
certificate of a Servicing Officer certifying as to the name and address of the
Person to which such Mortgage File or such document was delivered and the
purpose or purposes of such delivery.

         At any time that a Servicer is required to deliver to the Custodian a
Request for Release, the Servicer shall deliver two copies of the Request for
Release if delivered in hard

                                      G-3
<PAGE>
copy or the Servicer may furnish such Request for Release electronically to the
Custodian, in which event the Servicing Officer transmitting the same shall be
deemed to have signed the Request for Release. In connection with any Request
for Release of a Mortgage File because of a repurchase of a Mortgage Loan, such
Request for Release shall be followed by an assignment of mortgage, without
recourse, representation or warranty from the Trustee to the Seller and the
related Mortgage Note shall be endorsed without recourse by the Trustee and be
returned to the Seller. In connection with any Request for Release of a Mortgage
File because of the payment in full of a Mortgage Loan, such Request for Release
shall be accompanied by a certificate of satisfaction or other similar
instrument to be executed by or on behalf of the Trustee and returned to the
related Servicer.

Section 2.6. ASSUMPTION AGREEMENTS. In the event that any assumption agreement,
substitution of liability agreement or sale of servicing agreement is entered
into with respect to any Mortgage Loan subject to this Agreement in accordance
with the terms and provisions of the Pooling and Servicing Agreement, the Master
Servicer, to the extent provided in the related Servicing Agreement, shall cause
the related Servicer to notify the Custodian that such assumption or
substitution agreement has been completed by forwarding to the Custodian the
original of such assumption or substitution agreement, which shall be added to
the related Mortgage File and, for all purposes, shall be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting parts thereof.

                                  ARTICLE III
                            CONCERNING THE CUSTODIAN

         Section 3.1. CUSTODIAN AS BAILEE AND AGENT OF THE TRUSTEE. With respect
to each Mortgage Note, Mortgage and other documents constituting each Mortgage
File which are delivered to the Custodian, the Custodian is exclusively the
bailee and custodial agent of the Trustee and has no instructions to hold any
Mortgage Note or Mortgage for the benefit of any person other than the Trustee
and the Certificateholders and undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement and in the Pooling and
Servicing Agreement. Except upon compliance with the provisions of Section 2.5
of this Agreement, no Mortgage Note, Mortgage or Mortgage File shall be
delivered by the Custodian to the Depositor, the Servicers or the Master
Servicer or otherwise released from the possession of the Custodian.

         Section 3.2. Reserved.

         Section 3.3. CUSTODIAN MAY OWN CERTIFICATES. The Custodian in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

         Section 3.4. MASTER SERVICER TO PAY CUSTODIAN'S FEES AND EXPENSES. The
Master Servicer covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and performance of any of the powers and duties
hereunder of the Custodian, and the Master Servicer will pay or reimburse the
Custodian upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Custodian in accordance with any of the

                                      G-4
<PAGE>
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ), except any such expense, disbursement or advance as may arise from
its negligence or bad faith or to the extent that such cost or expense is
indemnified by the Depositor pursuant to the Pooling and Servicing Agreement.

         Section 3.5. CUSTODIAN MAY RESIGN TRUSTEE MAY REMOVE CUSTODIAN. The
Custodian may resign from the obligations and duties hereby imposed upon it as
such obligations and duties relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such written notice of resignation, the Trustee shall
either take custody of the Mortgage Files itself and give prompt written notice
thereof to the Depositor, the Master Servicer and the Custodian, or promptly
appoint a successor Custodian by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Custodian and one copy to
the successor Custodian. If the Trustee shall not have taken custody of the
Mortgage Files and no successor Custodian shall have been so appointed and have
accepted appointment within 30 days after the giving of such written notice of
resignation, the resigning Custodian may petition any court of competent
jurisdiction for the appointment of a successor Custodian.

         The Trustee may remove the Custodian at any time with the consent of
the Master Servicer. In such event, the Trustee shall appoint, or petition a
court of competent jurisdiction to appoint, a successor Custodian hereunder. Any
successor Custodian shall be a depository institution subject to supervision or
examination by federal or state authority, shall be able to satisfy the other
requirements contained in Section 3.7 and shall be unaffiliated with the
Servicer or the Depositor.

         Any resignation or removal of the Custodian and appointment of a
successor Custodian pursuant to any of the provisions of this Section 3.5 shall
become effective upon acceptance of appointment by the successor Custodian. The
Trustee shall give prompt notice to the Depositor and the Master Servicer of the
appointment of any successor Custodian. No successor Custodian shall be
appointed by the Trustee without the prior approval of the Depositor and the
Master Servicer.

         Section 3.6. MERGER OR CONSOLIDATION OF CUSTODIAN. Any Person into
which the Custodian 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 Custodian shall be a party, or any Person succeeding
to the business of the Custodian, shall be the successor of the Custodian
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

         Section 3.7. REPRESENTATIONS OF THE CUSTODIAN. The Custodian hereby
represents that it is a depository institution subject to supervision or
examination by a federal or state authority, has a combined capital and surplus
of at least $15,000,000 and is qualified to do business in the jurisdictions in
which it will hold any Mortgage File.

                            MISCELLANEOUS PROVISIONS

         Section 4.1. NOTICES. All notices, requests, consents and demands and
other communications required under this Agreement or pursuant to any other

in writing), in which case the notice will be deemed delivered when received.

         Section 4.2. AMENDMENTS. No modification or amendment of or supplement
to this Agreement shall be valid or effective unless the same is in writing and
signed by all parties hereto, and neither the Depositor, the Master Servicer nor
the Trustee shall enter into any amendment hereof except as permitted by the
Pooling and Servicing Agreement. The Trustee shall give prompt notice to the
Custodian of any amendment or supplement to the Pooling and Servicing Agreement
and furnish the Custodian with written copies thereof.

         Section 4.3. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED A CONTRACT
MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

         Section 4.4. RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Depositor and at the Trust's expense, but
only upon direction accompanied by an Opinion of Counsel reasonably satisfactory
to the Depositor to the effect that the failure to effect such recordation is
likely to materially and adversely affect the interests of the
Certificateholders.

         For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

         Section 4.5. SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

before the Cut-off Date (including payments collected after the Cut-off Date)

items of each Mortgage File, PROVIDED, HOWEVER, that in lieu of the foregoing,
the Mortgage Loan Seller may deliver the following documents, under the
circumstances set forth below: (w) in lieu of the original Security Instrument,
assignments

                                       J-4
<PAGE>
to the Trustee or intervening assignments thereof which have been delivered, are
being delivered or will, upon receipt of recording information relating to the
Security Instrument required to be included thereon, be delivered to recording
offices for recording and have not been returned to the Mortgage Loan Seller in
time to permit their delivery as specified above, the Mortgage Loan Seller may
deliver a true copy thereof with a certification by the Mortgage Loan Seller, on
the face of such copy, substantially as follows: "Certified to be a true and
correct copy of the original, which has been transmitted for recording"; (x) in
lieu of the Security Instrument, assignments to the Trustee or intervening
assignments thereof, if the applicable jurisdiction retains the originals of
such documents (as evidenced by a certification from the Mortgage Loan Seller to
such effect) the Mortgage Loan Seller may deliver photocopies of such documents
containing an original certification by the judicial or other governmental
authority of the jurisdiction where such documents were recorded; (y) in lieu of
the Mortgage Notes relating to the Mortgage Loans, each identified in the list
delivered by the Purchaser to the Trustee on the Closing Date and attached
hereto as Exhibit 5, the Mortgage Loan Seller may deliver lost note affidavits
and indemnities of the Mortgage Loan Seller; and (z) the Mortgage Loan Seller
shall not be required to deliver intervening assignments or Mortgage Note
endorsements between the related Underlying Seller and the Mortgage Loan Seller,
between the Mortgage Loan Seller and the Depositor, and between the Depositor
and the Trustee; and provided further, however, that in the case of Mortgage
Loans which have been prepaid in full after the Cut-off Date and prior to the
Closing Date, the Mortgage Loan Seller, in lieu of delivering the above
documents, may deliver to the Trustee a certification by the Mortgage Loan
Seller or the Master Servicer to such effect and shall deposit all amounts paid
in respect of such Mortgage Loans in the Master Servicer Collection Account on
the Closing Date. The Mortgage Loan Seller shall deliver such original documents
(including any original documents as to which certified copies had previously
been delivered) or such certified copies to the Trustee promptly after they are
received. The Mortgage Loan Seller shall cause the Mortgage and intervening
assignments, if any, and the assignment of the Security Instrument to be
recorded not later than 180 days after the Closing Date, unless such assignment
is not required to be recorded under the terms set forth in Section 6(a) hereof.

                  (c) In connection with the assignment of any Mortgage Loan
registered on the MERS(R) System, the Mortgage LoaN Seller further agrees that
it will cause, at the Mortgage Loan Seller's own expense, within 30 days after
the Closing Date, the MERS(R) System to indicate that such Mortgage Loans have
been assigned by the Mortgage LoaN Seller to the Purchaser and by the Purchaser
to the Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer files
(a) the code in the field which identifies the specific Trustee and (b) the code
in the field "Pool Field" which identifies the series of the Certificates issued
in connection with such Mortgage Loans. The Mortgage Loan Seller further agrees
that it will not, and will not permit any Servicer or the Master Servicer to,
and the Master Servicer agrees that it will not, alter the codes referenced in
this paragraph with respect to any Mortgage Loan during the term of the Pooling
and Servicing Agreement unless and until such Mortgage Loan is repurchased in
accordance with the terms of the Pooling and Servicing Agreement.

<PAGE>
                  (d) The Mortgage Loan Seller and the Purchaser acknowledge
hereunder that all of the Mortgage Loans and the related servicing will
ultimately be assigned to U.S. Bank National Association, as Trustee for the
Certificateholders, on the date hereof.

                  SECTION 5. EXAMINATION OF MORTGAGE FILES.

                  (a) On or before the Mortgage File Delivery Date, the Mortgage
Loan Seller will have made the Mortgage Files available to the Purchaser or its
agent for examination which may be at the offices of the Trustee or the Mortgage
Loan Seller and/or the Mortgage Loan Seller's custodian. The fact that the
Purchaser or its agent has conducted or has failed to conduct any partial or
complete examination of the Mortgage Files shall not affect the Purchaser's
rights to demand cure, repurchase, substitution or other relief as provided in
this Agreement. In furtherance of the foregoing, the Mortgage Loan Seller shall
make the Mortgage Files available to the Purchaser or its agent from time to
time so as to permit the Purchaser to confirm the Mortgage Loan Seller's
compliance with the delivery and recordation requirements of this Agreement and
the Pooling and Servicing Agreement. In addition, upon request of the Purchaser,
the Mortgage Loan Seller agrees to provide to the Purchaser, Bear Stearns and to
any investors or prospective investors in the Certificates information regarding
the Mortgage Loans and their servicing, to make the Mortgage Files available to
the Purchaser, Bear Stearns and to such investors or prospective investors
(which may be at the offices of the Mortgage Loan Seller and/or the Mortgage
Loan Seller's custodian) and to make available personnel knowledgeable about the
Mortgage Loans for discussions with the Purchaser, Bear Stearns and such
investors or prospective investors, upon reasonable request during regular
business hours, sufficient to permit the Purchaser, Bear Stearns and such
investors or potential investors to conduct such due diligence as any such party
reasonably believes is appropriate.

                  (b) Pursuant to the Pooling and Servicing Agreement, on the
Closing Date the Custodian, on behalf of the Trustee, for the benefit of the
Certificateholders, will acknowledge receipt of each Mortgage Loan, by delivery
to the Mortgage Loan Seller, the Purchaser and the Trustee of an initial
certification in the form attached as Exhibit One to the Custodial Agreement.

                  (c) Pursuant to the Pooling and Servicing Agreement, within 90
days of the Closing Date (or, with respect to any Substitute Mortgage Loan,
within five Business Days after the receipt by the Trustee or Custodian
thereof), the Trustee will review or shall cause the Custodian to review items
of the Mortgage Files as set forth on EXHIBIT 1 and will deliver to the Mortgage
Loan Seller, the Purchaser and the Trustee an interim certification
substantially in the form of Exhibit Two to the Custodial Agreement. If the
Trustee or Custodian, as its agent, finds any document listed on EXHIBIT 1 not
to have been executed or received, or to be unrelated, determined on the basis
of the Mortgagor name, original principal balance and loan number, to the
Mortgage Loans identified in the Final Mortgage Loan Schedule or to appear
defective on its face (a "MATERIAL DEFECT"), the Trustee or the Custodian, as
its agent, shall promptly notify the Mortgage Loan Seller of such Material
Defect. The Mortgage Loan Seller shall correct or cure any such Material Defect
within 90 days from the date

                                       J-6
<PAGE>
of notice from the Trustee or the Custodian, as its agent, of the Material
Defect and if the Mortgage Loan Seller fails to correct or cure such Material
Defect within such period and such defect materially and adversely affects the
interests of the Certificateholders in the related Mortgage Loan, the Mortgage
Loan Seller will, in accordance with the terms of the Pooling and Servicing
Agreement, within 90 days of the date of notice, provide the Trustee with a
Substitute Mortgage Loan (if within two years of the Closing Date) or purchase
the related Mortgage Loan at the applicable Purchase Price; PROVIDED THAT, if
such defect would cause the Mortgage Loan to be other than a "qualified
mortgage" as defined in Section 860G(a)(3) of the Code, any such cure,
repurchase or substitution must occur within 90 days from the date such breach
was discovered; PROVIDED, HOWEVER, that if such defect relates solely to the
inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy because the
originals of such documents, or a certified copy, have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date. The foregoing repurchase obligation shall not
apply in the event that the Mortgage Loan Seller cannot deliver such original or
copy of any document submitted for recording to the appropriate recording office
in the applicable jurisdiction because such document has not been returned by
such office; provided that the Mortgage Loan Seller shall instead deliver a
recording receipt of such recording office or, if such receipt is not available,
a certificate confirming that such documents have been accepted for recording,
and delivery to the Trustee or the Custodian, as its agent, shall be effected by
the Mortgage Loan Seller within thirty days of its receipt of the original
recorded document.

                  (d) Pursuant to the Pooling and Servicing Agreement, within
180 days of the Closing Date (or, with respect to any Substitute Mortgage Loan,
within five Business Days after the receipt by the Trustee or Custodian thereof)
the Trustee will review or cause the Custodian to review items of the Mortgage
Files as set forth on EXHIBIT 1 and will deliver to the Mortgage Loan Seller,
the Purchaser and the Trustee a final certification substantially in the form of
Exhibit Three to the Custodial Agreement. If the Trustee or Custodian, as its
agent, finds a Material Defect, the Trustee or the Custodian, as its agent,
shall promptly notify the Mortgage Loan Seller of such Material Defect. The
Mortgage Loan Seller shall correct or cure any such Material Defect within 90
days from the date of notice from the Trustee or the Custodian, as its agent, of
the Material Defect and if the Mortgage Loan Seller fails to correct or cure
such Material Defect within such period and such defect materially and adversely
affects the interests of the Certificateholders in the related Mortgage Loan,
the Mortgage Loan Seller will, in accordance with the terms of the Pooling and
Servicing Agreement, within 90 days of the date of notice, provide the Trustee
with a Substitute Mortgage Loan (if within two years of the Closing Date) or
purchase the related Mortgage Loan at the applicable Purchase Price; PROVIDED
THAT, if such defect would cause the Mortgage Loan to be other than a "qualified
mortgage" as defined in Section 860G(a)(3) of the Code, any such cure,
repurchase or substitution must occur within 90 days from the date such breach
was discovered; PROVIDED, HOWEVER, that if such defect relates solely to the
inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy because the
originals of such documents, or a certified copy, have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date. The foregoing repurchase obligation shall not
apply in the event that the Mortgage Loan Seller cannot deliver such original or
copy of any document submitted for recording to the appropriate recording office
in the applicable jurisdiction because such document has not been returned by
such office; provided that the Mortgage Loan Seller shall instead deliver a
recording receipt of such recording office or, if such receipt is not available,
a

                                       J-7
<PAGE>
certificate confirming that such documents have been accepted for recording, and
delivery to the Trustee or the Custodian, as its agent, shall be effected by the
Mortgage Loan Seller within thirty days of its receipt of the original recorded
document.

                  (e) At the time of any substitution, the Mortgage Loan Seller
shall deliver or cause to be delivered the Substitute Mortgage Loan, the related
Mortgage File and any other documents and payments required to be delivered in
connection with a substitution pursuant to the Pooling and Servicing Agreement.
At the time of any purchase or substitution, the Trustee in accordance with the
terms of the Pooling and Servicing Agreement shall (i) assign to the Mortgage
Loan Seller and cause the Custodian to release the documents (including, but not
limited to, the Mortgage, Mortgage Note and other contents of the Mortgage File)
in the possession of the Custodian relating to the Deleted Mortgage Loan and
(ii) execute and deliver such instruments of transfer or assignment, in each
case without recourse, as shall be necessary to vest in the Mortgage Loan Seller
title to such Deleted Mortgage Loan.

                  SECTION 6. RECORDATION OF ASSIGNMENTS OF MORTGAGE.

                  (a) The Mortgage Loan Seller shall cause each assignment of
the Security Instrument from the Mortgage Loan Seller to the Trustee to be
recorded not later than 180 days after the Closing Date, unless (a) such
recordation is not required by the Rating Agencies or an Opinion of Counsel has
been provided to the Trustee (with a copy to the Custodian) which states that
the recordation of such assignments is not necessary to protect the interests of
the Certificateholders in the related Mortgage Loans or (b) MERS is identified
on the Mortgage or a properly recorded assignment of the Mortgage, as the
Mortgagee of record solely as nominee for the Mortgage Loan Seller and its
successors and assigns; PROVIDED, HOWEVER, notwithstanding the foregoing, each
assignment shall be submitted for recording by the Mortgage Loan Seller in the
manner described above, at no expense to the Trust or Trustee, upon the earliest
to occur of (i) reasonable direction by the Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than 25% of the Trust, (ii)
the occurrence of a Event of Default, (iii) the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgage Loan Seller and (iv) the
occurrence of a servicing transfer as described in Section 8.02 of the Pooling
and Servicing Agreement.

                  While each such Mortgage or assignment is being recorded, if
necessary, the Mortgage Loan Seller shall leave or cause to be left with the
Trustee a certified copy of such Mortgage or assignment. All customary recording
fees and reasonable expenses relating to the recordation of the assignments of
mortgage to the Trustee or the Opinion of Counsel, as the case may be, shall be
borne by the Mortgage Loan Seller.

                  (b) It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser,
as contemplated by this Agreement be, and be treated as, a sale. It is, further,
not the intention of the parties that such conveyance be deemed a pledge of the
Mortgage Loans by the Mortgage Loan Seller to the Purchaser to secure a debt or
other obligation of the Mortgage Loan Seller. However, in the event that,
notwithstanding the intent of the parties, the Mortgage Loans are held by a
court to continue to be property of the Mortgage Loan Seller, then (a) this
Agreement shall also be deemed to be a security agreement within the meaning of
Articles 8 and 9 of the applicable

                                       J-8
<PAGE>
Uniform Commercial Code; (b) the transfer of the Mortgage Loans provided for
herein shall be deemed to be a grant by the Mortgage Loan Seller to the
Purchaser of a security interest in all of the Mortgage Loan Seller's right,
title and interest in and to the Mortgage Loans and all amounts payable to the
holders of the Mortgage Loans in accordance with the terms thereof and all
proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, securities or other property, to the extent the Purchaser
would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to
Section 4 hereof, including all amounts, other than investment earnings, from
time to time held or invested in any accounts created pursuant to the Pooling
and Servicing Agreement, whether in the form of cash, instruments, securities or
other property; (c) the possession by the Purchaser or the Trustee of Mortgage
Notes and such other items of property as constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession by the
secured party" for purposes of perfecting the security interest pursuant to
Section 9-313 (or comparable provision) of the applicable Uniform Commercial
Code; and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the
Purchaser for the purpose of perfecting such security interest under applicable
law. Any assignment of the interest of the Purchaser pursuant to any provision
hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed

Seller and the Purchaser shall, to the extent consistent with this Agreement,
take such actions as may be reasonably necessary to ensure that, if this
Agreement were deemed to create a security interest in the Mortgage Loans, such
security interest would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Pooling and Servicing Agreement.

                    (xiii) a lender's title insurance policy (on an ALTA or CLTA
               form) or binder, or other assurance of title customary in the
               relevant jurisdiction therefor in a form acceptable to Fannie Mae
               or Freddie Mac, was issued on the date that each Mortgage Loan
               was created by a title insurance company which, to the best of
               the Mortgage Loan Seller's knowledge, was qualified to do
               business in the jurisdiction where the related Mortgaged Property
               is located, insuring the Mortgage Loan Seller and its successors
               and assigns that the Mortgage is a first priority lien on the
               related Mortgaged Property in the original principal amount of
               the Mortgage Loan. The Mortgage Loan Seller is the sole insured
               under such lender's title insurance policy, and such policy,
               binder or assurance is valid and remains in full force and
               effect, and each such policy, binder or assurance shall contain

               and, the appraisal is in a form acceptable to Fannie Mae or

               loss by fire and such hazards as are covered under a standard
               extended coverage endorsement in the locale in which the
               Mortgaged Property is located, in an amount which is not less
               than the lesser of the maximum insurable value of the
               improvements securing such Mortgage Loan or the outstanding
               principal balance of the Mortgage Loan, but in no event in an
               amount less than an amount that is required to prevent the
               Mortgagor from being deemed to be a co-insurer thereunder; if the
               improvement on the Mortgaged Property is a condominium unit, it
               is included under the coverage afforded by a blanket policy for
               the condominium project; if upon origination of the related
               Mortgage Loan, the improvements on the Mortgaged Property were in
               an area identified as a federally designated flood area, a flood
               insurance policy is in effect in an amount representing coverage
               not less than the least of (i) the outstanding principal balance
               of the Mortgage Loan, (ii) the restorable cost of improvements
               located on such Mortgaged Property or (iii) the maximum coverage
               available under federal law; and each Mortgage obligates the
               Mortgagor thereunder to maintain the insurance referred to above
               at the Mortgagor's cost and expense;

                    (xvi) each Mortgage Loan constitutes a "qualified mortgage"
               under Section 860G(a)(3)(A) of the Code and Treasury Regulation
               Section 1.860G-2(a)(1);

                  SECTION 12. ACCOUNTANTS' LETTERS.

                  (a) Deloitte & Touche LLP will review the characteristics of a
sample of the Mortgage Loans described in the Final Mortgage Loan Schedule and

contained in the Prospectus Supplement under the captions "Summary of Prospectus
Supplement--The Mortgage Loans" and "The Mortgage Pool" and in Schedule A

                  SECTION 13. INDEMNIFICATION.

                  (a) The Mortgage Loan Seller shall indemnify and hold harmless
the Purchaser and its directors, officers and controlling persons (as defined in
Section 15 of the Securities Act) from and against any loss, claim, damage or
liability or action in respect thereof, to which they or any of them may become
subject, under the Securities Act or otherwise, insofar

                                       J-18
<PAGE>
as such loss, claim, damage, liability or action arises out of, or is based upon
(i) any untrue statement of a material fact contained in the MORTGAGE LOAN
SELLER'S INFORMATION as identified in EXHIBIT 3, the omission to state in the
Prospectus Supplement or Prospectus (or any amendment thereof or supplement
thereto approved by the Mortgage Loan Seller and in which additional Mortgage
Loan Seller's Information is identified), in reliance upon and in conformity
with Mortgage Loan Seller's Information a material fact required to be stated
therein or necessary to make the statements therein in light of the
circumstances in which they were made, not misleading, (ii) any representation
or warranty assigned or made by the Mortgage Loan Seller in Section 7 or Section
8 hereof being, or alleged to be, untrue or incorrect, or (iii) any failure by
the Mortgage Loan Seller to perform its obligations under this Agreement; and
the Mortgage Loan Seller shall reimburse the Purchaser and each other
indemnified party for any legal and other expenses reasonably incurred by them
in connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action.

         The foregoing indemnity agreement is in addition to any liability which
the Mortgage Loan Seller otherwise may have to the Purchaser or any other such
indemnified party.

                  (b) The Purchaser shall indemnify and hold harmless the
Mortgage Loan Seller and its respective directors, officers and controlling
persons (as defined in Section 15 of the Securities Act) from and against any
loss, claim, damage or liability or action in respect thereof, to which they or
any of them may become subject, under the Securities Act or otherwise, insofar
as such loss, claim, damage, liability or action arises out of, or is based upon
(i) any untrue statement of a material fact contained in the PURCHASER'S
INFORMATION as identified in EXHIBIT 4, the omission to state in the Prospectus
Supplement or Prospectus (or any amendment thereof or supplement thereto
approved by the Purchaser and in which additional Purchaser's Information is
identified), in reliance upon and in conformity with the Purchaser's
Information, a material fact required to be stated therein or necessary to make
the statements therein in light of the circumstances in which they were made,
not misleading, (ii) any representation or warranty made by the Purchaser in
Section 9 hereof being, or alleged to be, untrue or incorrect, or (iii) any
failure by the Purchaser to perform its obligations under this Agreement; and
the Purchaser shall reimburse the Mortgage Loan Seller, and each other
indemnified party for any legal and other expenses reasonably incurred by them
in connection with investigating or defending or preparing to defend any such
loss, claim, damage, liability or action. The foregoing indemnity agreement is
in addition to any liability which the Purchaser otherwise may have to the
Mortgage Loan Seller, or any other such indemnified party.

                  (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 13 except to the extent that it
has been prejudiced in any material respect by such failure or from any
liability which it may have otherwise). In case any such action is brought
against any indemnified party, and it notifies an indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent it may elect by written notice delivered to the
indemnified party promptly (but, in any event, within 30 days) after receiving
the aforesaid notice from such indemnified party, to

                                       J-19
<PAGE>
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by one of the indemnifying parties in connection
with the defense of such action, (ii) the indemnifying parties shall not have
employed counsel to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there is a
conflict of interest between itself or themselves and the indemnifying party in
the conduct of the defense of any claim or that the interests of the indemnified
party or parties are not substantially co-extensive with those of the
indemnifying party (in which case the indemnifying parties shall not have the
right to direct the defense of such action on behalf of the indemnified party or
parties), in any of which events such fees and expenses shall be borne by the
indemnifying parties (PROVIDED, HOWEVER, that the indemnifying party shall be
liable only for the fees and expenses of one counsel in addition to one local
counsel in the jurisdiction involved. Anything in this subsection to the
contrary notwithstanding, an indemnifying party shall not be liable for any
settlement or any claim or action effected without its written consent;
PROVIDED, HOWEVER, that such consent was not unreasonably withheld.

                  (d) If the indemnification provided for in paragraphs (a) and
(b) of this Section 13 shall for any reason be unavailable to an indemnified
party in respect of any loss, claim, damage or liability, or any action in
respect thereof, referred to in Section 13, then the indemnifying party shall in
lieu of indemnifying the indemnified party contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability, or action in respect thereof, in such proportion as shall be
appropriate to reflect the relative benefits received by the Mortgage Loan
Seller on the one hand and the Purchaser on the other from the purchase and sale
of the Mortgage Loans, the offering of the Certificates and the other
transactions contemplated hereunder. No person found liable for a fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who is not also found liable
for such fraudulent misrepresentation.

                  (e) The parties hereto agree that reliance by an indemnified
party on any publicly available information or any information or directions
furnished by an indemnifying party shall not constitute negligence, bad faith or
willful misconduct by such indemnified party.

                  SECTION 14. NOTICES. All demands, notices and communications
hereunder shall be in writing but may be delivered by facsimile transmission
subsequently confirmed in writing. Notices to the Mortgage Loan Seller shall be
directed to EMC Mortgage Corporation, Mac Arthur Ridge II, 909 Hidden Ridge
Drive, Suite 200, Irving, Texas 75038 (Telecopy: (972-444-2880)), and notices to
the Purchaser shall be directed to Structured Asset Mortgage Investments II
Inc., 383 Madison Avenue, New York, New York 10179 (Telecopy: (212-272-7206)),
Attention: Baron Silverstein; or to any other address as may hereafter be
furnished by one party to the other party by like notice. Any such demand,
notice or communication hereunder shall be deemed to have been received on the
date received at the premises of the addressee (as evidenced, in the case of
registered or certified mail, by the date noted on the return receipt) provided
that it is received on a business day during normal business hours and, if

                                       J-20
<PAGE>

received after normal business hours, then it shall be deemed to be received on
the next business day.

                  SECTION 15. TRANSFER OF MORTGAGE LOANS. The Purchaser retains
the right to assign the Mortgage Loans and any or all of its interest under this
Agreement to the Trustee without the consent of the Mortgage Loan Seller, and,
upon such assignment, the Trustee shall succeed to the applicable rights and
obligations of the Purchaser hereunder; PROVIDED, HOWEVER, the Purchaser shall
remain entitled to the benefits set forth in Sections 11, 13 and 17 hereto and
as provided in Section 2(a). Notwithstanding the foregoing, the sole and
exclusive right and remedy of the Trustee with respect to a breach of
representation or warranty of the Mortgage Loan Seller shall be the purchase or
substitution obligations of the Mortgage Loan Seller contained in Sections 5 and
7 hereof.

                  SECTION 16. TERMINATION. This Agreement may be terminated (a)
by the mutual consent of the parties hereto prior to the Closing Date, (b) by
the Purchaser, if the conditions to the Purchaser's obligation to close set
forth under Section 10(a) hereof are not fulfilled as and when required to be
fulfilled or (c) by the Mortgage Loan Seller, if the conditions to the Mortgage
Loan Seller's obligation to close set forth under Section 10(b) hereof are not
fulfilled as and when required to be fulfilled. In the event of termination
pursuant to clause (b), the Mortgage Loan Seller shall pay, and in the event of
termination pursuant to clause (c), the Purchaser shall pay, all reasonable
out-of-pocket expenses incurred by the other in connection with the transactions
contemplated by this Agreement. In the event of a termination pursuant to clause
(a), each party shall be responsible for its own expenses.

                  SECTION 17. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO
SURVIVE DELIVERY. All representations, warranties and agreements contained in
this Agreement, or contained in certificates of officers of the Mortgage Loan
Seller submitted pursuant hereto, shall remain operative and in full force and
effect and shall survive delivery of the Mortgage Loans to the Purchaser (and by
the Purchaser to the Trustee). Subsequent to the delivery of the Mortgage Loans
to the Purchaser, the Mortgage Loan Seller's representations and warranties
contained herein with respect to the Mortgage Loans shall be deemed to relate to
the Mortgage Loans actually delivered to the Purchaser and included in the Final
Mortgage Loan Schedule and any Substitute Mortgage Loan and not to those
Mortgage Loans deleted from the Preliminary Mortgage Loan Schedule pursuant to
Section 3 hereof prior to the Closing.

                  SECTION 18. SEVERABILITY. If any provision of this Agreement
shall be prohibited or invalid under applicable law, the Agreement shall be
ineffective only to such extent, without invalidating the remainder of this
Agreement.

                  SECTION 19. COUNTERPARTS. This Agreement may be executed in
counterparts, each of which will be an original, but which together shall
constitute one and the same agreement.

                  SECTION 20. AMENDMENT. This Agreement cannot be amended or
modified in any manner without the prior written consent of each party.

                                       J-21
<PAGE>

                  SECTION 21. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO
HAVE BEEN MADE AND PERFORMED IN THE STATE OF NEW YORK AND SHALL BE INTERPRETED
IN ACCORDANCE WITH THE LAWS OF SUCH STATE, WITHOUT REGARD TO CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE.

                  SECTION 22. FURTHER ASSURANCES. Each of the parties agrees to
execute and deliver such instruments and take such actions as another party may,
from time to time, reasonably request in order to effectuate the purpose and to
carry out the terms of this Agreement including any amendments hereto which may
be required by either Rating Agency.

                  SECTION 23. SUCCESSORS AND ASSIGNS.

                  This Agreement shall bind and inure to the benefit of and be
enforceable by the Mortgage Loan Seller and the Purchaser and their permitted
successors and assigns and, to the extent specified in Section 13 hereof, Bear
Stearns, and their directors, officers and controlling persons (within the
meaning of federal securities laws). The Mortgage Loan Seller acknowledges and
agrees that the Purchaser may assign its rights under this Agreement (including,
without limitation, with respect to the Mortgage Loan Seller's representations
and warranties respecting the Mortgage Loans) to the Trustee. Any person into
which the Mortgage Loan Seller may be merged or consolidated (or any person
resulting from any merger or consolidation involving the Mortgage Loan Seller),
any person resulting from a change in form of the Mortgage Loan Seller or any
person succeeding to the business of the Mortgage Loan Seller, shall be
considered the "successor" of the Mortgage Loan Seller hereunder and shall be
considered a party hereto without the execution or filing of any paper or any
further act or consent on the part of any party hereto. Except as provided in
the two preceding sentences, this Agreement cannot be assigned, pledged or
hypothecated by either party hereto without the written consent of the other
parties to this Agreement and any such assignment or purported assignment shall
be deemed null and void.

                  SECTION 24. THE MORTGAGE LOAN SELLER. The Mortgage Loan Seller
will keep in full effect all rights as are necessary to perform their respective
obligations under this Agreement.

                  SECTION 25. ENTIRE AGREEMENT. This Agreement contains the
entire agreement and understanding between the parties with respect to the
subject matter hereof, and supersedes all prior and contemporaneous agreements,
understandings, inducements and conditions, express or implied, oral or written,
of any nature whatsoever with respect to the subject matter hereof.

                  SECTION 26. NO PARTNERSHIP. Nothing herein contained shall be
deemed or construed to create a partnership or joint venture between the parties
hereto.

         APPENDIX E: Standard & Poor's Predatory Lending Categorization

         Standard & Poor's has categorized loans governed by anti-predatory
lending laws in the Jurisdictions listed below into three categories based upon
a combination of factors that include (a) the risk exposure associated with the
assignee liability and (b) the tests and thresholds set forth in those laws.
Note that certain loans classified by the relevant statute as Covered are
included in Standard & Poor's High Cost Loan Category because they included
thresholds and tests that are typical of what is generally considered High Cost
by the industry.

Re:  Letter of Engagement for
Consulting Services 

Gentlemen: 

Thank you for the opportunity to
submit this letter of engagement to assist Duckwall-ALCO (“DA” or the “Company”).
AlixPartners, LLC (“AlixPartners”) welcomes the opportunity to collaborate with
DA in its efforts to improve operating performance and enhance shareholder value. This
letter describes an approach that is designed to create a plan for improving the
performance of DA. Subsequent work may involve implementation of this plan. The terms of
which will be documented in a separate agreement. 

This letter outlines the
understanding between AlixPartners and DA of the objective, tasks, work product, staffing
and economic model for the engagement of AlixPartners to design a program to improve the
operating performance of DA. 

   

 

OBJECTIVE
  

Based on our discussions, the
objective for this effort is clear: 

To develop a prioritized action plan
that, if successful, can increase the EBITDA of DA, enable DA to compete more
effectively, and ultimately increase shareholder value. 

TASKS
  

The tasks associated with this
effort will focus in four areas: strategy, finance, operations, and information
technology. 

We will have a small team
  led by Mark Toney that will perform the QuickStrikeTM
  analysis and develop the plan. That team will report directly to a subcommittee
  of the Board of Directors of DA. 

OVERSIGHT
  

AlixPartners will report directly to
the Board subcommittee. Further, Mr. Glen Shank, the Chairman of the Board and President
of DA, will work with our team throughout the assessment to ensure that AlixPartners
receives accurate information in a timely manner. 

WORK
  PRODUCT 

Our work product from Phase One will
be in the form of: 

	•	Information to be discussed with the
      Board and others, as you may direct.

	•	Written reports and analysis worksheets
      to support our suggestions as we deem necessary or as you may request.

STAFFING
  

Mark Toney will be responsible for
the Phase One engagement. Mark will provide project oversight and manage the work efforts
of the team. He will be assisted by consultants at various levels, all of whom have a
wide range of skills and abilities related to this type of assignment. 

We anticipate initially using a team
of three on-site consultants for Phase One of the engagement, plus Mr. Toney. We will
also leverage our in-house research staff and capabilities, and we may call on other
subject matter experts (at no incremental cost to DA) to add to our understanding and
capabilities. 

   

ECONOMIC
  MODEL 

The economic model for this
engagement is described in Schedule 2. We typically work for a combination of hourly fees
and contingent success fees. Due to the nature of the work in this initial phase, we do
not believe a success fee approach is appropriate. Instead, we will bill hourly and
commit to a fixed cost. 

We will require a retainer of
$100,000 to be applied against the time charges and expenses specific to the engagement
in accordance with Section 2 of the attached General Terms and Conditions. 

*        *        *
  

The terms and conditions set out in
the attached Schedules and the General Terms and Conditions form part of and are
incorporated by reference herein to this agreement. 

Thank you for considering
AlixPartners for this important assignment. If these terms meet with your approval,
please sign and return the enclosed copy of this letter and wire transfer the amount to
establish the retainer. 

Sincerely yours, 

ALIXPARTNERS,
  LLC

DISCLOSURES
  

We know of no fact or situation that
would represent a conflict of interest for us with regard to the Company. However, we
have not completed a thorough check of the parties in interest with regard to the
Company, as we have not received the list of the parties in interest. However, as soon as
practicable after receiving the list, we will provide you with a listing of parties with
whom we have current or prior relationships that may be related to the Company. We will
provide this so that you might assess the impact, if any, that you believe such
disclosures have upon our relationship. 

The Parties agree that this Schedule

between AlixPartners and the interested parties.

it relates. The Company agrees that no such advice shall be used for any other purpose or
reproduced, disseminated, quoted, or referred to with attribution to AlixPartners at any
time, in any manner, or for any purpose other than accomplishing the services referred to
herein without AlixPartners’ prior approval (which shall not be unreasonably
withheld) except as required by law. 

Section 5.
Intellectual Property. 

Except for those methodologies,
processes techniques, ideas, concepts and know-how developed independently by

Section 6. Framework

any other type of financial statement reporting or consulting engagement that is subject

Section 7.
 Indemnification 

In consideration of our agreement to
act on your behalf in connection with this engagement, you agree to indemnify, hold
harmless, and defend us (including our principals, employees, and agents) from and
against all claims, liabilities, losses, damages, and reasonable expenses as they are
incurred, including reasonable legal fees and disbursements of counsel, and the costs of
our professional time (our professional time will be reimbursed at our rates in effect
when such future time is required), relating to or arising out of the engagement,
including any legal proceeding in which we may be required or agree to participate but in
which we are not a party. We, our principals, employees, and agents, may, but are not
required to, engage a single firm of separate counsel of our choice in connection with
any of the matters to which this indemnification agreement relates. This indemnification
agreement does not apply to actions taken or omitted to be taken by us in bad faith.

remedies with respect to any third party products or services, are against the third
party vendor and not against AlixPartners. 

Section 8.
 Disclosures.

other than those disclosed in Schedule 3, which would represent a conflict of interest
for us with regard to the Company. 

While we are not aware of any
relationships, other than those disclosed in Schedule 3, that connect us to any party in
interest, because AlixPartners is a consulting firm that serves clients on a national
basis in numerous cases, it is possible that AlixPartners may have rendered services to
or have business associations with other entities which had or have relationships with
the Company. AlixPartners has not and will not represent the interests of any of these
aforementioned entities in this case, involving the Company.

  may award costs and attorneys’ fees to the prevailing party. Judgment on
  the award rendered by the arbitrators may be entered in any court having jurisdiction
  thereof.
