</TABLE>

         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

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

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

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 June 2008 and the above delinquency and loss
tests are met, then the Group I Senior Prepayment Percentage for such

denominator of which is the Scheduled Principal Balance of the Mortgage Loans as
of the beginning of the related Due Period, exceeds such percentage as of the
Cut-off Date, then the Group I Senior Prepayment Percentage for such
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

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.

Mortgage Loan Schedule.

         GROUP II SENIOR CERTIFICATES: The Class II-A-1, Class II-A-2, Class

July 25, 2016 and thereafter       Group III Senior Percentage
</TABLE>

         In addition, no reduction of the Group III 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
including July 2012 and June 2013, (b) 35% of the Original Subordinate Principal
Balance if such Distribution Date occurs between and including July 2013 and
June 2014, (c) 40% of the Original Subordinate Principal Balance if such
Distribution Date occurs between and including July 2014 and June 2015, (d) 45%
of the Original Subordinate Principal Balance if such Distribution Date occurs
between and including July 2015 and June 2016, and (e) 50% of the Original
Subordinate Principal Balance if such Distribution Date occurs during or after
July 2016.

         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
the aggregate Current Principal Amount of the Subordinate Certificates does not
exceed 50% and (b)(i) on or prior to the Distribution Date in June 2008
cumulative Realized Losses on the Mortgage Loans as of the end of the related
Prepayment Period do not exceed 20% of the Original Subordinate Principal
Balance and (ii) after the Distribution Date in June 2008 cumulative Realized
Losses on the Mortgage Loans as of the end of the related Prepayment Period do
not exceed 30% of the Original Subordinate Principal Balance, then, the Group
III Senior Prepayment Percentage for such Distribution Date will equal the Group
III 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 June 2008 and the above delinquency
and loss tests are met, then the Group III Senior Prepayment Percentage for such
Distribution Date will equal the Group III Senior Percentage plus 50% of the
Group III 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
of the beginning of the related Due Period, exceeds such percentage as of the
Cut-off Date, then the Group III Senior Prepayment Percentage for such
Distribution Date will equal 100%. On the Distribution Date on which the Current
Principal Amounts of the Group III Senior Certificates are reduced to zero, the
Group III Senior Prepayment Percentage shall be the minimum percentage
sufficient to effect such reduction and thereafter shall be zero.

         GROUP III SUBORDINATE PERCENTAGE: On any Distribution Date, 100% minus
the Group III Senior Percentage.

         GROUP III SUBORDINATE PREPAYMENT PERCENTAGE: With respect to the Group
III Mortgage Loans, on any Distribution Date, 100% minus the Group III Senior
Prepayment Percentage, except that on any Distribution Date after the Current
Principal Amounts of the Group III 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 III
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 III Senior Certificates have each been reduced to
zero, then the Group III Subordinate Prepayment Percentage will equal zero for
such Distribution Date.

         GROUP IV MORTGAGE LOANS: The Mortgage Loans identified as such on the
Mortgage Loan Schedule.

         GROUP IV SENIOR CERTIFICATES: The Class IV-A-1 Certificates.

         GROUP IV SENIOR PERCENTAGE: Initially, 94.85%. On any Distribution
Date, the lesser of (i) 100% and (ii) the percentage (carried to six places
rounded up) obtained by dividing the aggregate Current Principal Amount of the
Group IV Senior Certificates immediately preceding such Distribution Date by the
aggregate Scheduled Principal Balance of the Group IV Mortgage Loans as of the
beginning of the related Due Period.

         In addition, no reduction of the Group IV Senior Prepayment Percentage

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

Distribution Date occurs between and including July 2014 and June 2015, (d) 45%
of the Original Subordinate Principal Balance if such Distribution Date occurs
between and including July 2015 and June 2016, and (e) 50% of the Original
Subordinate Principal Balance if such Distribution Date occurs during or after
July 2016.

         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

Balance and (ii) after the Distribution Date in June 2008 cumulative Realized
Losses on the Mortgage Loans as of the end of the related Prepayment Period do
not exceed 30% of the Original Subordinate Principal Balance, then, the Group IV
Senior Prepayment Percentage for such Distribution Date will equal the Group IV
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 June 2008 and the above delinquency and loss
tests are met, then the Group IV Senior Prepayment Percentage for such
Distribution Date will equal the Group IV Senior Percentage plus 50% of the
Group IV 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
of the beginning of the related Due Period, exceeds such percentage as of the
Cut-off Date, then the Group IV Senior Prepayment Percentage for such
Distribution Date will equal 100%. On the Distribution Date on which the Current
Principal Amounts of the Group IV Senior Certificates are reduced to zero, the
Group IV Senior Prepayment Percentage shall be the minimum percentage sufficient
to effect such reduction and thereafter shall be zero.

         GROUP IV SUBORDINATE PERCENTAGE: On any Distribution Date, 100% minus
the Group IV Senior Percentage.

         GROUP IV SUBORDINATE PREPAYMENT PERCENTAGE: With respect to the Group

Subordinate Prepayment Percentage will equal 100%. If the test set forth in the

Principal Amount of the Group IV Senior Certificates have each been reduced to
zero, then the Group IV Subordinate Prepayment Percentage will equal zero for
such Distribution Date.

                                   ARTICLE II

         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 their
respective Mortgage Loan Schedules, 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 Paying Agent 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) such assets as shall
from time to time be credited or are required by the terms of this Agreement to
be credited to the Distribution Account 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 (A)
to the order of the Trustee, or (B) in the case of a loan registered on the MERS
system, in blank, and in each case 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 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 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, with respect to the Mortgage Loans, the
Custodian 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 related
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 related 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 Certificateholders in the related Mortgage Loan, the Trustee
shall enforce the Seller's obligation under the Mortgage Loan Purchase
Agreement, 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 (or with respect to
any Substitute Mortgage Loan, within five Business Days after the receipt by the
Trustee or the Custodian thereof), 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, 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 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 Master Servicer,
Securities Administrator, the Paying Agent and the Trustee written notification
detailing the components of the Repurchase Price to the Trustee, the Paying
Agent and the Master Servicer. 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 Paying Agent. The Trustee or the Custodian,
as agent of 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 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 to the Trustee,
the Paying Agent and the Master Servicer. 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 such notification, the Seller shall provide to the Paying
Agent 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, the
Securities Administrator 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 delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders.

         (b) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the Mortgage Loans and the other assets of REMIC I (other than, for the
avoidance of doubt, the Market Value Swap) for the benefit of the holders of the
REMIC I Interests. The Trustee acknowledges receipt of such assets and declares
that it holds and will hold the same in trust for the exclusive use and benefit
of the holders of the REMIC I Interests.

         (c) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC I Regular Interests and the other assets of REMIC II for the
benefit of the Holders of the REMIC II Interests. The Trustee acknowledges
receipt of the REMIC I Regular Interests (which are uncertificated) and the
other assets of REMIC II and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the Holders of the REMIC II
Interests.

         (d) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC II Regular Interests and the other assets of REMIC II for the
benefit of the Holders of the REMIC III Certificates. The Trustee acknowledges
receipt of the REMIC II Regular Interests (which are uncertificated) and the
other assets of REMIC III and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the Holders of the REMIC III
Certificates.

                                   ARTICLE III

                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

         Section 3.01 Master Servicer.

         The Master Servicer shall, from and after the Closing Date, 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 or the Custodian, as its agent, shall provide access to the
records and documentation in the possession of the Custodian 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 Custodian; provided, however,
that, unless otherwise required by law, the Trustee or the Custodian, as its
agent, 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 or the Custodian, as its agent, 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 or the Custodian'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 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 into 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 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 Master Servicer Collection 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 Servicer 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 Master Servicer Collection Account (which the
Master Servicer hereby agrees to pay to the Trustee from the Master Servicer
Collection Account upon demand) or, to the extent not paid from such account,
the Trustee shall be entitled to reimburse itself for such costs and expenses
from the Distribution Account. 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 servicer to service the
Mortgage Loans in accordance with the related 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
Agreements.

         (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 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 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 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.

         (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).

         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 Trustee), upon the execution or receipt thereof the originals of any

         Section 3.13 Realization Upon Defaulted Mortgage Loans.

         The Master Servicer shall cause each Servicer (to the extent required
under the related Servicing Agreement) to foreclose upon, repossess or otherwise

satisfactory arrangements can be made for collection of delinquent payments, all
in accordance with the applicable Servicing Agreement.

         Section 3.14 Compensation for the Master Servicer.

         The Master Servicer will be entitled to all income and gain realized

Collection Account, pursuant to Article IV, for the performance of its
activities hereunder. Servicing compensation in the form of assumption fees, if
any, late payment charges, as collected, if any, or otherwise (but not including
any prepayment premium or penalty) shall be retained by the applicable Servicer
and shall not be deposited in the Protected Account. The Master Servicer shall
be required to pay all expenses incurred by it in connection with its activities
hereunder and shall not be entitled to reimbursement therefor except as provided
in this Agreement.

         Section 3.15 REO Property.

         (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Mortgage Loan, the deed or certificate of sale shall
be issued to the Trustee, or to its nominee, on behalf of the related
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
the Protected Account.

         (c) The Master Servicer and the applicable Servicer, upon the final
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 the related
Master Servicer Collection Account on the next succeeding Servicer Remittance
Date.

         Section 3.16 Annual Officer's Certificate as to Compliance.

         (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, 2006, 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, 2006 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 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, 2006 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, 2006, or such earlier filing date as may be
required by the Commission, and (ii) unless and until a Form 15 Suspension
Notice shall have been filed, March 31 of each year thereafter, or such earlier
filing date as may be required by the Commission, the Securities Administrator
shall file a Form 10-K, in substance conforming to 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 3.19 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 3.20 Optional Purchase of Defaulted Mortgage Loans.

(a) With respect to any Mortgage Loan which as of the first day of a Fiscal
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 Fiscal 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 Fiscal 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) The Master Servicer shall enforce the obligation of each Servicer

Permitted Investments shall mature, or shall be subject to redemption or
withdrawal, no later than the date on which such funds are required to be

Days of receipt of notification of such loss but not later than the second
Business Day prior to the Distribution Date on which the moneys so invested are

                  (i) Scheduled Payments on the Mortgage Loans received or any
related portion thereof advanced by such Servicer pursuant to its Servicing
Agreement which were due on or before the related Due Date, net of the amount

                  (ii) Full Principal Prepayments and any Liquidation Proceeds

for the Mortgage Loans in the related Prepayment Period; and

                  (iv) Any amount to be used as a Monthly Advance.

         (d) Withdrawals may be made from an Account only to make remittances as
provided in Section 4.01(c), 4.02 and 4.03; to reimburse the Master Servicer or
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
accordance with Section 10.01. As provided in Sections 4.01(a) and 4.02(b)
certain amounts otherwise due to the Servicers may be retained by them and need
not be deposited in the Master Servicer Collection Account.

         Section 4.02 Master Servicer Collection Account.

         (a) The Master Servicer shall establish and maintain in the name of the
Trustee, for the benefit of the Certificateholders, the Master Servicer

Master Servicer and as received by the Master Servicer, the following amounts:

                  (i) Any amounts withdrawn from a Protected Account;

                  (ii) Any Monthly Advance and any Compensating Interest

         (b) All amounts deposited to the Master Servicer Collection Account
shall be held by the Master Servicer in the name of the Trustee in trust for the
benefit of the Certificateholders in accordance with the terms and provisions of
this Agreement. The requirements for crediting the Master Servicer Collection

fees and charges and (ii) the items enumerated in Subsections 4.05(a)(i), (ii),
(iii), (iv), (vi), (vii), (viii), (ix) and (x), need not be credited by the
Master Servicer or the related Servicer to the Distribution Account or the
Master Servicer Collection Account, as applicable. In the event that the Master
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
shall be for the account of the Master Servicer. The Master Servicer from time
to time shall be permitted to withdraw or receive distribution of any and all
investment earnings from the Master Servicer Collection Account. The risk of
loss of moneys required to be distributed to the Certificateholders resulting
from such investments shall be borne by and be the risk of the Master Servicer.
The Master Servicer shall deposit the amount of any such loss in the Master
Servicer Collection Account within two Business Days of receipt of notification
of such loss but not later than the second Business Day prior to the
Distribution Date on which the moneys so invested are required to be distributed
to the Certificateholders.

         Section 4.03 Permitted Withdrawals and Transfers from the Master
Servicer Collection Account.

         (a) The Master Servicer will, from time to time on demand of a Servicer
or the Securities Administrator, make or cause to be made such withdrawals or

related Servicing Agreement. The Master Servicer may clear and terminate the
Master Servicer Collection Account pursuant to Section 10.01 and remove amounts
from time to time deposited in error.

         (b) On an ongoing basis, the Master Servicer shall withdraw from the
Master Servicer Collection Account (i) any expenses, costs and liabilities
recoverable by the Trustee, the Master Servicer or the Securities Administrator
or the Custodian pursuant to Sections 3.03, 7.04 and 9.05 and (ii) any amounts
payable to the Master Servicer as set forth in Section 3.14; provided, however,
that the Master Servicer shall be obligated to pay from its own funds any
amounts which it is required to pay under Section 7.03(a).

         (c) In addition, on or before each Distribution Account Deposit Date,
the Master Servicer shall deposit in the Distribution Account (or remit to the

Master Servicer with respect to the Mortgage Loans.

         (d) No later than 3:00 p.m. New York time on each Distribution Account

         (a) The Paying Agent shall establish and maintain in the name of the
Paying Agent, for the benefit of the Certificateholders, the Distribution
Account as a segregated trust account or accounts.

         (b) All amounts deposited to the Distribution Account shall be held by
the Paying Agent in the name of the Paying Agent in trust for the benefit of the
Certificateholders in accordance with the terms and provisions of this
Agreement.

         (c) The Paying Agent shall deposit in the Distribution Account the
Repurchase Price with respect to any Mortgage Loans purchased by the Seller
pursuant to the Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03
hereof, any amounts which are to be treated pursuant to Section 2.04 of this
Agreement as the payment of a Repurchase Price in connection with the tender of
a Substitute Mortgage Loan by the Seller, the Repurchase Price with respect to
any Mortgage Loans purchased by the Company pursuant to Section 3.20, and all
proceeds of any Mortgage Loans or property acquired with respect thereto
repurchased by the Depositor or its designee pursuant to Section 10.01;

         (d) The Distribution Account shall constitute a trust account of the
Trust Fund segregated on the books of the Paying Agent and held by the Paying
Agent in trust in its Corporate Trust Office, and the Distribution Account and
the funds deposited therein shall not be subject to, and shall be protected
from, all claims, liens, and encumbrances of any creditors or depositors of the
Paying Agent or the Master Servicer (whether made directly, or indirectly
through a liquidator or receiver of the Paying Agent 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 Paying Agent, in such Permitted Investments as may be selected by
the Master Servicer or deposited in demand deposits with such depository

from funds uninvested therein from time to time shall be for the account of the
Master Servicer. The Master Servicer shall be permitted to withdraw or receive
distribution of any and all investment earnings from the Distribution Account on
each Distribution Date. If there is any loss on a Permitted Investment or demand
deposit, the Master Servicer shall remit the amount of the loss to the Paying
Agent who shall deposit such amount in the Distribution Account. With respect to
the Distribution Account and the funds 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 Paying Agent) 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 Securities Administrator 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar cause such Class
to become Global Certificates, the Certificate Registrar 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 Certificate Registrar in
writing that the Depository is no longer willing or able to properly discharge
its responsibilities as Depository and (B) the Certificate Registrar or the
Depositor is unable to locate a qualified successor within 30 days or (ii) the
Depositor at its option advises the Certificate Registrar in writing that it
elects to terminate the book-entry system through the Depository, the
Certificate Registrar, as agent of the Depositor, 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 Certificate Registrar, as
agent of the Depositor, of the Certificates by the Depository, accompanied by
registration instructions from the Depository for registration, the Certificate
Registrar shall issue the definitive Certificates. Neither the Depositor nor the
Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar of instructions from the Depository
directing the Certificate Registrar 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 Certificate Registrar), (i) the Certificate Registrar shall instruct the
Depository to reduce the related Depository Participant's account by the
aggregate Current Principal Amount of the definitive Certificate, (ii) the
Certificate Registrar 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 Certificate Registrar 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.

         (c) (i)  REMIC I will be evidenced by (x) the REMIC I Regular
Interests, which will be uncertificated and non-transferable and are hereby
designated as the "regular interests" in REMIC I and have the initial principal
amounts and accrue interest at the Pass-Through Rates equal to those set forth
in this Section 5.01(c)(i) and (y) the Class R-I Certificates, which are hereby
designated as representing the sole class of "residual interests" in REMIC I.

         The REMIC I Regular Interests and the Class R-I Certificate will have
the following designations, initial principal amounts and Pass-Through Rates:

is a larger number than in the preceding distribution period, the least amount
of principal shall 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, so as to keep the Uncertificated Principal Balance of each REMIC I

         (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 Certificate Registrar shall
sign, countersign and shall deliver them at the direction of the Depositor.
Pending the preparation of definitive Certificates of any Class, the Certificate
Registrar may sign and countersign temporary Certificates that are printed,
lithographed or typewritten, in authorized denominations for Certificates of
such Class, substantially of the tenor 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 Certificate Registrar, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar or its agent. A Certificate
bearing the manual and facsimile signatures of individuals who were the
authorized signatories of the Certificate Registrar or its agent at the time of
issuance shall bind the Certificate Registrar, 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 Certificate Registrar 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

         OF SUCH PERSON WILL NOT RESULT IN OR CONSTITUTE A NONEXEMPT PROHIBITED
         TRANSACTION, IS PERMISSIBLE UNDER APPLICABLE LAW AND WILL NOT GIVE RISE
         TO ANY ADDITIONAL OBLIGATIONS ON THE PART OF THE DEPOSITOR, THE MASTER
         SERVICER, THE SECURITIES ADMINISTRATOR, CERTIFICATE REGISTRAR OR THE
         TRUSTEE.

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 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

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.

         Section 5.02 Registration of Transfer and Exchange of Certificates.

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

         (b) Subject to Subsection 5.01(a) and, in the case of any Global

the Certificate Registrar 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 Certificate Registrar shall register the transfer of
an Individual Certificate if the requested transfer is being made to a

Certificate or comparable evidence as to its QIB status.

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

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 Certificate Registrar shall register such

                  (ii) In the case of a beneficial interest in a Class of Global

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 Certificate
Registrar shall register such transfer if the transferee has provided the
Certificate Registrar 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:

                  (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

                  (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

         (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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar 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 Certificate
Registrar 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 Certificate Registrar shall, within five
Business Days 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 Certificate Registrar shall sign and
countersign and the Certificate Registrar shall deliver the Certificates which
the Certificateholder making the exchange is entitled to receive.

         (j) If the Certificate Registrar 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 Certificate Registrar, 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 Certificate Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

         (l) The Certificate Registrar 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.

Certificate of any such Class in exchange therefor or upon transfer thereof:

         ANY TRANSFEREE OF THIS CERTIFICATE, PRIOR TO THE MANDATORY AUCTION
         DISTRIBUTION DATE (AS DEFINED IN THE AGREEMENT), WILL BE DEEMED TO HAVE
         REPRESENTED BY VIRTUE OF ITS PURCHASE OR HOLDING OF THIS CERTIFICATE
         (OR INTEREST HEREIN) THAT EITHER (A) SUCH TRANSFEREE IS NOT A PERSON
         (INCLUDING AN INVESTMENT MANAGER, A NAMED FIDUCIARY OR A TRUSTEE OF ANY
         SUCH PLAN) ACTING, DIRECTLY OR INDIRECTLY, ON BEHALF OF OR PURCHASING
         ANY CERTIFICATE WITH "PLAN ASSETS" OF ANY PLAN (A "PLAN INVESTOR") OR
         (B) ITS HOLDING OR ACQUISITION OF THIS CERTIFICATE SHALL NOT RESULT IN
         A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF THE EMPLOYEE
         RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED ("ERISA"), OR
         SECTION 4975 OF THE INTERNAL REVENUE CODE (THE "CODE") BECAUSE IT
         SATISFIES THE REQUIREMENTS FOR EXEMPTIVE RELIEF PROVIDED UNDER
         PROHIBITED TRANSACTION CLASS EXEMPTION ("PTE") 84-14, 90-1, 91-38,
         95-60 OR 96-23.

         Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Certificate Registrar such security or indemnity as it may require to
save it harmless, and (iii) the Certificate Registrar has not received notice
that such Certificate has been acquired by a third Person, the Certificate
Registrar 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 Certificate Registrar and shall be of no further
effect and evidence no rights.

         (b) Upon the issuance of any new Certificate under this Section 5.03,
the Certificate Registrar 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 Certificate
Registrar) 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 Paying Agent, the Certificate Registrar, the
Trustee and any agent of the Depositor, the Paying Agent, the Certificate
Registrar 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 Paying Agent, the Certificate Registrar, the Trustee
nor any agent of the Depositor, the Paying Agent, the Certificate Registrar, 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.

transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee, the Certificate Registrar 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 Certificate Registrar, 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 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, the Certificate Registrar 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 Certificate Registrar 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
Certificate Registrar may require an Opinion of Counsel addressed to the
Certificate Registrar 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 Code, unless the proposed
transferee provides either (i) the Trustee or the Securities Administrator, with
an Opinion of Counsel addressed to the Depositor, the Trustee, the Certificate
Registrar, the Master Servicer and the Securities Administrator (upon which they
may rely) which is satisfactory to the Trustee or the Securities Administrator,
which opinion will not be at the expense of the Depositor, the Trustee, the
Certificate Registrar, 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 Certificate Registrar, the Securities
Administrator or the Trustee to any obligation in addition to those undertaken
in the Agreement or (ii) in the case of the Private Certificates, a
representation or certification to the Certificate Registrar (upon which the
Trustee and the Certificate Registrar are 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 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, Class B-3, Class
B-4, Class B-5, Class B-6, Class B-7, Class B-8 or Class B-9 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.

         (d) Neither the Trustee, the Certificate Registrar, 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
Certificate Registrar, the Securities Administrator and the Master Servicer from
and against any and all liabilities, claims, costs or expenses incurred by the
Trustee, the Certificate Registrar, the Securities Administrator or the Master
Servicer as a result of such attempted or purported transfer. Neither the
Trustee, nor the Certificate Registrar shall be liable 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.

         (e) Any person acquiring an interest in a Mandatory Auction Certificate
before the Mandatory Auction Distribution Date shall be deemed to have
represented to the Trustee that either (i) it is not acquiring an interest in
such Certificate directly or indirectly by, or on behalf of, or with assets of
an employee benefit plan or other retirement arrangement which is subject to
Title I of ERISA and/or Section 4975 of the Code, or (ii) the acquisition and
holding of the Certificate are eligible for the exemptive relief available under

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 or PTE 96-23 (Class Exemption for Plan Asset Transactions
Determined by In-House Asset Managers).

         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,
upon the request of such holder or prospective purchaser, the information
required to be provided to such holder or prospective purchaser by Rule
144A(d)(4) under the Securities Act; and (2) the Depositor shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the
Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A.

         Section 5.09 Appointment of Paying Agent and Certificate Registrar.

         Wells Fargo Bank, National Association, as Securities Administrator,
shall act as the initial Paying Agent and Certificate Registrar for so long as
it is also the Master Servicer. Each of the Paying Agent and the Certificate
Registrar may resign upon thirty (30) days' prior written notice to the Trustee;
provided hereto that no such resignation shall be effective until the
appointment of a successor paying agent or certificate registrar. In the event
the Paying Agent and/or the Certificate Registrar resigns or is removed by the
Trustee for cause, the Trustee may appoint a successor paying agent or
certificate registrar, as applicable. The Trustee shall cause such successor
paying agent, if other than the Trustee or the Master Servicer or the Securities
Administrator, to execute and deliver to the Trustee an instrument in which such
paying agent shall agree with the Trustee that such paying agent will hold all
sums held by it for the payment to Certificateholders in trust for the benefit
of the Certificateholders entitled thereto until such sums have been paid to the
Certificateholders.

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 the Group I, Group II, Group III or Group IV 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 the
Group I, Group II, Group III or Group IV 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-12 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 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-12 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  SECOND, to the Class B-11 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  THIRD, to the Class B-10 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  FOURTH, to the Class B-9 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  FIFTH, to the Class B-8 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  SIXTH, to the Class B-7 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

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

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

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

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

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

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

                  THIRTEENTH, if such loss is on (w) a Group I Mortgage Loan, 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, Class II-A-2, Class II-A-3 Certificates, on a pro rata basis,
         until the Current Principal Amounts thereof have been reduced to zero;
         (y) a Group III Mortgage Loan, to the Class III-A-1 Certificates until
         the Current Principal Amount thereof has been reduced to zero; or (z) a
         Group IV Mortgage Loan, to the Class IV-A-1 Certificates until the
         Current Principal Amount thereof has been reduced to zero; and

                  FOURTEENTH, 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 Amount 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").

         (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 Paying Agent 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 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 Paying Agent 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 Paying
Agent 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 Paying Agent 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 Paying
Agent 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 Paying Agent 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

Prepayment Percentage, Group I, Group II, Group III and Group IV Subordinate

         The information set forth above shall be calculated or reported, as the
case may be, by the Securities Administrator, based solely on, and to the extent
of, information provided to the Securities Administrator by the Master Servicer.
The Securities Administrator may conclusively rely on such information and shall
not be required to confirm, verify or recalculate any such information.

         The Securities Administrator may make available each month, to any
interested party, the monthly statement to Certificateholders via the Securities
Administrator's website initially located at "www.ctslink.com." Assistance in
using the website can be obtained by calling the Securities Administrator's
customer service desk at (301) 815-6600. Parties that are unable to use the
above distribution option are entitled to have a paper copy mailed to them via
first class mail by calling the Securities Administrator's customer service desk
and indicating such. The Securities Administrator shall have the right to change
the way such reports are distributed in order to make such distribution more
convenient and/or more accessible to the parties, and the Securities
Administrator shall provide timely and adequate notification to all parties
regarding any such change.

         (b) By April 30 of each year beginning in 2006, the Securities
Adminsitrator 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 subclauses (a)(ii) and (a)(v) above with respect to the
Certificates, plus information with respect to the amount of servicing
compensation and such other customary information as the Securities
Administrator may determine to be necessary and/or to be required by the
Internal Revenue Service or by a federal or state law or rules or regulations to
enable such Holders to prepare their tax returns for such calendar year. Such
obligations 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 and Securities
Administrator (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.

         (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 a party to the Wells Fargo Servicing Agreement pursuant to
Section 3.03, and any officer, director, 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 the 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 Agreement, 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 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 any Servicers, with the exception of Wells Fargo, 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 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

                  (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.

                                   ARTICLE IX

             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 Paying Agent 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 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.

         (e) All funds received by the Master Servicer and the Trustee and
required to be deposited in the Master Servicer Collection Account or
Distribution Account pursuant to this Agreement will be promptly so deposited by
the Master Servicer and the Trustee.

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

         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
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of 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 Trustee 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 Trustee 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.

         Section 9.03 Trustee and Securities Administrator Not Liable for
Certificates or Mortgage Loans.

         The recitals contained herein and in the Certificates (other than the
signature and countersignature of the Certificate Registrar 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
Auction Administration Agreement, the Market Value Swap or Certificates (other
than the signature and countersignature of the Certificate Registrar 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,
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) or incurred or made by the Trustee or the Securities
Administrator, respectively, in the administration of the trusts hereunder and
under the Auction Administration Agreement and the Market Value Swap (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, Paying Agent and
Securities Administrator.

         The Trustee and any successor Trustee, Paying Agent and any successor
Paying Agent and the Securities Administrator and any successor Securities
Administrator shall during the entire duration of this Agreement be a state bank
or trust company or a national banking association 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 rated "BBB" or higher by S&P and
"Baa2" or higher by Moody's with respect to any outstanding long-term unsecured
unsubordinated debt, and, in the case of a successor Trustee, successor Paying
Agent or successor Securities Administrator other than pursuant to Section 9.10,
rated in one of the two highest long-term debt categories of, or 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, the Paying Agent 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.

         Section 9.07 Insurance.

         The Trustee, Paying Agent 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, the
Paying Agent or the Securities Administrator as to the Trustee's, Paying Agent's
or the Securities Administrator's, respectively, compliance with this Section
9.07 shall be furnished to any Certificateholder upon reasonable written
request.

         Section 9.08 Resignation and Removal of the Trustee and Securities
Administrator.

         (a) The Trustee and the Securities Administrator may at any time resign
and be discharged from the Trust hereby created by giving written notice thereof
to the Depositor and the Master Servicer, with a copy to the Rating Agencies.
Upon receiving such notice of resignation, the Depositor shall promptly appoint
a successor Trustee or successor Securities Administrator, as applicable, by
written instrument, in triplicate, one copy of which instrument shall be
delivered to each of the resigning Trustee or Securities Administrator, as
applicable, the successor Trustee or Securities Administrator, as applicable. If
no successor Trustee or Securities Administrator shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee or Securities Administrator may petition any
court of competent jurisdiction for the appointment of a successor Trustee or
Securities Administrator.

         (b) If at any time the Trustee, the Paying Agent or the Securities
Administrator shall cease to be eligible in accordance with the provisions of
Section 9.06 and shall fail to resign after written request therefor by the
Depositor or if at any time the Trustee, the Paying Agent or the Securities
Administrator shall become incapable of acting, or shall be adjudged a bankrupt
or insolvent, or a receiver of the Trustee, the Paying Agent or the Securities
Administrator, as applicable, or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee, the Paying Agent or
the Securities Administrator, as applicable, or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, or in the event of a
Termination Event in respect of the Auction Administrator under the Market Value
Swap, then the Depositor shall promptly remove the Trustee, or shall be entitled
to remove the Paying Agent or the Securities Administrator, as applicable, and
appoint a successor Trustee, Paying Agent or Securities Administrator, as
applicable, by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the Trustee, the Paying Agent or Securities
Administrator, as applicable, so removed, the successor Trustee or Securities
Administrator, as applicable.

         (c) The Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund may at any time remove
the Trustee, the Paying Agent or the Securities Administrator and appoint a
successor Trustee, the Paying Agent or Securities Administrator by written
instrument or instruments, in quadruplicate, signed by such Holders or their
attorneys-in-fact duly authorized, one complete set of which instruments shall
be delivered to the Depositor, the Paying Agent, the Master Servicer, the
Securities Administrator (if the Trustee is removed), the Trustee (if the
Securities Administrator or Paying Agent is removed), and the Trustee, the
Paying Agent or Securities Administrator so removed and the successor so
appointed. In the event that the Trustee, the Paying Agent or Securities
Administrator is removed by the Holders of Certificates in accordance with this
Section 9.08(c), the Holders of such Certificates shall be responsible for
paying any compensation payable to a successor Trustee, successor Paying Agent
or successor Securities Administrator, in excess of the amount paid to the
predecessor Trustee, predecessor Paying Agent or predecessor Securities
Administrator, as applicable.

         (d) No resignation or removal of the Trustee, the Paying Agent or the
Securities Administrator and appointment of a successor Trustee, the Paying
Agent or Securities Administrator pursuant to any of the provisions of this
Section 9.08 shall become effective except upon appointment of and acceptance of
such appointment by the successor Trustee, Paying Agent or Securities
Administrator as provided in Section 9.09.

         (e) No resignation or removal of the Securities Administrator and
appointment of a successor Securities Administrator pursuant to any of the
provisions of this Section 9.08 shall become effective except upon the
simultaneous appointment of and acceptance of a successor Auction Administrator
as provided in Section 11.02.

         Section 9.09 Successor Trustee, Successor Paying Agent and Successor
Securities Administrator.

         (a) Any successor Trustee, Paying Agent or Securities Administrator
appointed as provided in Section 9.08 shall execute, acknowledge and deliver to
the Depositor and to its predecessor Trustee, Paying Agent or Securities
Administrator an instrument accepting such appointment hereunder. The
resignation or removal of the predecessor Trustee, Paying Agent or Securities
Administrator shall then become effective and such successor Trustee, Paying
Agent 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 originally named as Trustee,
Paying Agent or Securities Administrator herein. The predecessor Trustee, Paying
Agent or Securities Administrator shall after payment of its outstanding fees
and expenses promptly deliver to the successor Trustee, Paying Agent or
Securities Administrator, as applicable, all assets and records of the Trust
held by it hereunder, and the Depositor and the predecessor Trustee, Paying
Agent 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, Paying
Agent or Securities Administrator, as applicable, all such rights, powers,
duties and obligations.

         (b) No successor Trustee, Paying Agent or Securities Administrator
shall accept appointment as provided in this Section 9.09 unless at the time of
such acceptance such successor Trustee, Paying Agent or Securities Administrator
shall be eligible under the provisions of Section 9.06.

         (c) Upon acceptance of appointment by a successor Trustee, Paying Agent
or Securities Administrator as provided in this Section 9.09, the successor
Trustee, Paying Agent or Securities Administrator shall mail notice of the
succession of such Trustee, Paying Agent or Securities Administrator hereunder
to all Certificateholders at their addresses as shown in the Certificate
Register and to the Rating Agencies. The Company shall pay the cost of any
mailing by the successor Trustee, Paying Agent or Securities Administrator.

         Section 9.10 Merger or Consolidation of Trustee, Paying Agent or
Securities Administrator.

         Any state bank or trust company or national banking association into
which the Trustee, Paying Agent 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 banking association resulting from any merger, conversion or
consolidation to 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, Paying Agent or the Securities Administrator,
respectively, shall be the successor of the Trustee, Paying Agent 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 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.

         (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 Internal Revenue Service
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, Internal Revenue Service 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, 2005 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 Treasury Regulation Section 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.

         (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, or in respect 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
payments of, or in respect of, interest or original issue discount 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.

                                   TERMINATION

         Section 10.01 Termination Upon Repurchase by the Depositor or its
Designee or Liquidation of the Mortgage Loans.

         (a) Subject to Section 10.02, the respective obligations and
responsibilities of the Depositor, the Trustee, the Paying Agent, the Master
Servicer and the Securities Administrator created hereby, other than the
obligation of the Paying Agent to make payments to Certificateholders as
hereinafter set forth shall terminate upon:

                  (i) the repurchase by or at the direction of the Depositor or
its designee of all of the Mortgage Loans and all related REO Property remaining
in the Trust at a price (in each case, the "Termination Purchase Price") equal
to 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 earlier of (i) the latest possible maturity date specified in Section
5.01(d) and (ii) 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 is
conditioned upon (i) such purchase occurring after the Distribution Date on
which the the aggregate Scheduled Principal Balance of the Mortgage Loans is
less than 10% of the sum of the aggregate Scheduled Principal Balance of the
Mortgage Loans as of the Cut-off Date, or (ii) the Depositor making a
determination, based upon an Opinion of Counsel addressed to the Depositor, the
Trustee and the Securities Administrator, 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 Paying Agent shall give notice of any termination to the
Certificateholders, with a copy to the Master Servicer, the Securities
Administrator, the Trustee and the Rating Agencies, upon which the
Certificateholders shall surrender their Certificates to the Paying Agent 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 Paying Agent 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 Paying Agent 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 Paying Agent 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 Paying Agent 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 or the Custodian, as its agent, 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 Paying Agent'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.

         (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 Paying Agent 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
Paying Agent 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 Paying Agent 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 Paying Agent'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 Paying Agent shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Paying Agent 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 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

                  (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.

         (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.

                                   ARTICLE XI

                          MANDATORY AUCTION PROVISIONS

         Section 11.01 The Market Value Swap and Auction Administration
Agreement. On the Closing Date, the Securities Administrator shall authorize and
direct the Auction Administrator to enter into the Market Value Swap and the
Auction Administration Agreement with the Swap Counterparty. The Market Value
Swap will not be part of the Trust Fund or of REMIC I, REMIC II or REMIC III.

         Section 11.02 Removal of the Auction Administrator. In the event of
resignation or removal of the Auction Administrator under the Auction
Administration Agreement, the Depositor shall select a new Auction Administrator
in accordance with this Section 11.02 and Article IX. Any successor Auction
Administrator shall meet the requirements of a successor Securities
Administrator under this Agreement.

         Section 11.03 Mandatory Auction Certificates. On the Mandatory Auction
Distribution Date with respect to each Mandatory Auction Certificate, except
after the occurrence of a Swap Termination Event, the Holder of such Mandatory
Auction Certificate hereby agrees to tender its Certificate to the Securities
Administrator on such Mandatory Auction Distribution Date in exchange for the
Par Price and acknowledges that the Securities Administrator shall cause the
Depository to terminate its ownership interest at that time. If a
Certificateholder fails to surrender a Certificate not held in book-entry form
by the close of business on the related Mandatory Auction Distribution Date for
any reason, such Certificate shall be deemed to be tendered and surrendered for
registration of transfer to the Securities Administrator and the Securities
Administrator shall sign, countersign and deliver in the name of the Mandatory
Auction Winner a new Certificate of a like Class and aggregated Fractional
Undivided Interest, but bearing a different number. The Par Price due to the
holders of cancelled, but not surrendered, Certificates shall be paid only upon
surrender of the Certificates, without any accrued interest on such Par Price
from the related Mandatory Auction Distribution Date.

                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS

         Section 12.01 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 12.02 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, and provided, further, that any amendment to Article XI of
this Agreement shall also require the consent of the Auction Administrator.

         (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, and provided, further, that any amendment to
Article XI of this Agreement shall also require the consent of the Auction
Administrator. Notwithstanding any other provision of this Agreement, for
purposes of the giving or withholding of consents pursuant to this Section
12.02(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.

         (d) In the case of an amendment under Subsection 12.02(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 12.03 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 12.04 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 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 12.04, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

         Section 12.05 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 12.05.

         (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 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 12.02(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.

         THIS AGREEMENT AND THE CERTIFICATES SHALL BE CONSTRUED IN ACCORDANCE

                                  SERIES 2005-4

         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, the Securities
Administrator 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, Securities Administrator 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 Mortgage Loans were sold by EMC Mortgage Corporation ("EMC") to SAMI
II. Wells Fargo Bank, N.A. ("Wells Fargo") will act as master servicer and as
securities administrator of the Mortgage Loans (the "Master Servicer" and the
"Securities Administrator", which terms include 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 SAMI II, as depositor (the "Depositor"), Wells Fargo, as
Master Servicer, securities administrator (in such capacity, the "Securities
Administrator") and auction administrator (in such capacity, the "Auction
Administrator"), EMC as seller and company 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 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 Paying
Agent 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 Securities Administrator 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 Paying
Agent of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the
Securities Administrator 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 twenty-two 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, the Securities Administrator
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 Certificate Registrar upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator 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 Securities Administrator 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
Securities Administrator, 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 Securities
Administrator, 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 Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

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, the Securities
Adminsitrator 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, the Securities Administrator 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 Bank, N.A. ("Wells Fargo") will act as master servicer and
securities administrator of the Mortgage Loans (the "Master Servicer" and the
"Securities Administrator", which terms include 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 SAMI II, as depositor (the "Depositor"), Wells Fargo, as
Master Servicer, securities administrator (in such capacity, the "Securities
Administrator") and auction administrator (in such capacity, the "Auction
Administrator"), EMC as seller and company 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 as 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 Paying
Agent 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 Securities Administrator 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 Paying
Agent of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the
Securities Administrator 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-10, Class B-11 and Class B-12] [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 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, Class B-3, Class B-4, Class B-5,
Class B-6, Class B-7, Class B-8 and Class B-9] [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 a 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-10, Class B-11 and Class B-12] [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 twenty-two 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, the Securities Administrator
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 Certificate Registrar upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator 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 Securities Administrator, 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 Securities Administrator, 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 Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

                                  SERIES 2005-4

         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 [_____________] 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 Bank, N.A. ("Wells Fargo") will act as master servicer and the
securities administrator of the Mortgage Loans (the "Master Servicer" and the
"Securities Administrator", which terms include 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 SAMI II, as depositor (the "Depositor"), Wells Fargo, as
Master Servicer and securities administrator (in such capacity, the "Securities
Administrator"), EMC as seller and company 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 Paying
Agent 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 Securities Administrator 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 Paying
Agent of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the
Securities Administrator 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, or section 4975 of the Internal Revenue Code of 1986, as
amended, unless the proposed transferee provides the Trustee with an opinion of
counsel for the benefit of the Depositor, Master Servicer and the Securities
Administrator and on which they may rely (which shall not be at the expense of
the Trustee) 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
obligations on the part of the Seller, the Master Servicer, any Servicer, the
Securities Administrator 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 twenty-two 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, the Securities Administrator
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 Certificate Registrar upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator 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 Securities Administrator, 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 Securities Administrator, 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 Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

                           acknowledge you have no obligation), the Privately
                           Offered Certificate is sold in a transaction that

herein shall have the meanings assigned in the Original Pooling and Servicing
Agreement, unless otherwise required by the context herein.

                                   ARTICLE II.
                          CUSTODY OF MORTGAGE DOCUMENTS

                  Section 2.1. CUSTODIAN TO ACT AS AGENT: ACCEPTANCE OF MORTGAGE
FILES. The Custodian, as the duly appointed custodial agent of the Trustee for
these purposes, acknowledges (subject to any exceptions noted in the Initial
Certification referred to in Section 2.3(a)), receipt of the Mortgage Files
relating to the Mortgage Loans identified on the schedule attached hereto (the
"Mortgage Files") and declares that it holds and will hold such Mortgage Files
as agent for the Trustee, in trust, for the use and benefit of all present and
future Certificateholders.

                  Section 2.2. RECORDATION OF ASSIGNMENTS. If any Mortgage File
includes one or more assignments of Mortgage to the Trustee in a state which is
specifically excluded from the Opinion of Counsel delivered by the Seller to the
Trustee and the Custodian pursuant to the provisions of Section 2.01 of the
Pooling and Servicing Agreement, each such assignment shall be delivered by the
Custodian to the Depositor for the purpose of recording it in the appropriate
public office for real property records, and the Depositor, at no expense to the
Custodian, shall promptly cause to be recorded in the appropriate public office
for real property records each such assignment of Mortgage and, upon receipt
thereof from such public office, shall return each such assignment of Mortgage
to the Custodian.

                  Section 2.3. REVIEW OF MORTGAGE FILES.

                  (a) On or prior to the Closing Date, in accordance with
Section 2.02 of the Pooling and Servicing Agreement, the Custodian shall deliver
to the Trustee an Initial Certification in the form annexed hereto as Exhibit
One evidencing receipt (subject to any exceptions noted therein) of a Mortgage
File for each of the Mortgage Loans listed on the Schedule attached hereto (the
"Mortgage Loan Schedule").

                  (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 Servicing Agreement, each such
document, and shall deliver to the Depositor and the Trustee an Interim
Certification in the form annexed hereto as Exhibit Two to the effect that all
such documents have been executed and received and that such documents relate to
the Mortgage Loans identified on the Mortgage Loan Schedule, except for any
exceptions listed on Schedule A attached to such Interim Certification. The
Custodian shall be under no 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 2.02 of the
Pooling and Servicing Agreement and deliver to the Depositor and the Trustee a
Final Certification in the form annexed hereto as Exhibit Three evidencing the
completeness of the Mortgage Files.

                  (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.

         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 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 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.

                                   ARTICLE IV.
                            MISCELLANEOUS PROVISIONS

                  Section 4.1. NOTICES. All notices, requests, consents and
demands and other communications required under this Agreement or pursuant to
any other instrument or document delivered hereunder shall be in writing and,
unless otherwise specifically provided, may be delivered personally, by telegram
or telex, or by registered or certified mail, postage prepaid, return receipt
requested, at the addresses specified on the signature page hereof (unless
changed by the particular party whose address is stated herein by similar notice
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
INCLUDING SECTIONS 5-1401 AND 5-1402 OF NEW YORK GENERAL OBLIGATIONS LAW BUT
OTHERWISE WITHOUT REGARD TO CONFLICT OF LAW PRINCIPALS.

                  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.

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; (iii) 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

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

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.

                  Section 8.4. The Mortgage Loan Seller and the Purchaser
acknowledge hereunder that all of the Mortgage Loans and the related servicing

the Certificateholders, on the date hereof.

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.

                  Section 9.2. 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.

                  Section 9.3. 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 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.

                  Section 9.4. 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 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.

                  Section 9.5. 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.

               ARTICLE X. RECORDATION OF ASSIGNMENTS OF MORTGAGE.

                  Section 10.1. 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 assignment is not necessary to protect the
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 Mortgage Loan Seller and
its successors and assigns; PROVIDED, HOWEVER, notwithstanding the delivery of
any such Opinion of Counsel, each assignment of Mortgage shall be submitted for
recording by the Mortgage Loan Seller in the manner described above, at no
expense to the Trust Fund 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 an 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.

                  Section 10.2. 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 of competent jurisdiction to continue to be property of the
Mortgage Loan Seller, then (i) this Agreement shall also be deemed to be a
security agreement within the meaning of Articles 8 and 9 of the applicable
Uniform Commercial Code; (ii) 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; (iii) 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 (iv) 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
to be an assignment of any security interest created hereby. The Mortgage Loan
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.

                  ARTICLE XI. REPRESENTATIONS AND WARRANTIES OF MORTGAGE LOAN
SELLER CONCERNING THE MORTGAGE LOANS. THE MORTGAGE LOAN SELLER HEREBY REPRESENTS
AND WARRANTS TO THE PURCHASER AS OF THE CLOSING DATE, OR SUCH OTHER DATE AS MAY
BE SPECIFIED BELOW WITH RESPECT TO EACH MORTGAGE LOAN BEING SOLD BY IT, THAT:

                  (a) the information set forth in the Mortgage Loan Schedule
         hereto is true and correct in all material respects and the information
         provided to the Rating Agencies, including the Mortgage Loan level
         detail, is true and correct according to the Rating Agency
         requirements;

                  (b) immediately prior to the transfer to the Purchaser, the
         Mortgage Loan Seller was the sole owner of beneficial title and holder
         of each Mortgage and Mortgage Note relating to the Mortgage Loans and
         is conveying the same free and clear of any and all liens, claims,
         encumbrances, participation interests, equities, pledges, charges or
         security interests of any nature and the Mortgage Loan Seller has full
         right and authority to sell or assign the same pursuant to this
         Agreement;

                  (c) to the best of the Mortgage Loan Seller's knowledge, each
         Mortgage Loan at the time it was made complied in all material respects
         with all applicable laws and regulations, including, without
         limitation, usury, equal credit opportunity, disclosure and recording
         laws and all applicable anti-predatory lending laws; and to the best of
         the Mortgage Loan Seller's knowledge, each Mortgage Loan has been
         serviced in all material respects in accordance with all applicable
         laws and regulations, including, without limitation, usury, equal
         credit opportunity, disclosure and recording laws and all applicable
         anti-predatory lending laws and the terms of the related Mortgage Note,
         the Mortgage and other loan documents;

                  (d) there is no monetary default existing under any Mortgage
         or the related Mortgage Note and there is no material event which, with
         the passage of time or with notice and the expiration of any grace or
         cure period, would constitute a default, breach or event of
         acceleration; and neither the Mortgage Loan Seller, any of its
         affiliates nor any servicer of any related Mortgage Loan has taken any
         action to waive any default, breach or event of acceleration; and no
         foreclosure action is threatened or has been commenced with respect to
         the Mortgage Loan;

                  (e) the terms of the Mortgage Note and the Mortgage have not
         been impaired, waived, altered or modified in any respect, except by
         written instruments, (i) if required by law in the jurisdiction where
         the Mortgaged Property is located, or (ii) to protect the interests of
         the Trustee on behalf of the Certificateholders;

                  (f) no selection procedure reasonably believed by the Mortgage
         Loan Seller to be adverse to the interests of the Certificateholders
         was utilized in selecting the Mortgage Loans;

                  (g) each Mortgage is a valid and enforceable first lien on the
         property securing the related Mortgage Note and each Mortgaged Property
         is owned by the Mortgagor in fee simple (except with respect to common
         areas in the case of condominiums, PUDs and DE MINIMIS PUDs) or by
         leasehold for a term longer than the term of the related Mortgage,
         subject only to (i) the lien of current real property taxes and
         assessments, (ii) covenants, conditions and restrictions, rights of
         way, easements and other matters of public record as of the date of
         recording of such Mortgage, such exceptions being acceptable to
         mortgage lending institutions generally or specifically reflected in
         the appraisal obtained in connection with the origination of the
         related Mortgage Loan or referred to in the lender's title insurance
         policy delivered to the originator of the related Mortgage Loan and
         (iii) other matters to which like properties are commonly subject which
         do not materially interfere with the benefits of the security intended
         to be provided by such Mortgage;

                  (h) there is no mechanics' lien or claim for work, labor or
         material affecting the premises subject to any Mortgage which is or may
         be a lien prior to, or equal with, the lien of such Mortgage except
         those which are insured against by the title insurance policy referred
         to in (xiii) below;

                  (i) as of the Cut-off Date, to the best of the Mortgage Loan
         Seller's knowledge, there was no delinquent tax or assessment lien
         against the property subject to any Mortgage, except where such lien
         was being contested in good faith and a stay had been granted against
         levying on the property;

                  (j) there is no valid offset, defense or counterclaim to any
         Mortgage Note or Mortgage, including the obligation of the Mortgagor to
         pay the unpaid principal and interest on such Mortgage Note;

                  (k) to the best of the Mortgage Loan Seller's knowledge,
         except to the extent insurance is in place which will cover such
         damage, the physical property subject to any Mortgage is free of
         material damage and is in good repair and there is no proceeding
         pending or threatened for the total or partial condemnation of any
         Mortgaged Property;

                  (l) to the best of the Mortgage Loan Seller's knowledge, the
         Mortgaged Property and all improvements thereon comply with all
         requirements of any applicable zoning and subdivision laws and
         ordinances;

                  (m) 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 all
         applicable endorsements including a negative amortization endorsement,
         if applicable;

                  (n) at the time of origination, each Mortgaged Property was
         the subject of an appraisal which conformed to the underwriting
         requirements of the originator of the Mortgage Loan and, the appraisal
         is in a form acceptable to Fannie Mae or FHLMC;

                  (o) as of the Closing Date, the improvements on each Mortgaged
         Property securing a Mortgage Loan are insured (by an insurer which is
         acceptable to the Mortgage Loan Seller) against 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;

                  (p) 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);

                  (q) Each Mortgage Loan was originated with an initial
         mortgagee of record, or was originated in conformity with the
         underwriting standards of and purchased by a subsequent mortgagee, that
         was either (x) a savings and loan association, savings bank, commercial
         bank, credit union, insurance company, or similar institution which is
         supervised and examined by a Federal or State authority or (y) a
         mortgagee approved by the Secretary of Housing and Urban Development
         pursuant to sections 203 and 211 of the National Housing Act.

                  (r) none of the Mortgage Loans are (a) loans subject to 12 CFR
         Part 226.31, 12 CFR Part 226.32 or 12 CFR Part 226.34 of Regulation Z,
         the regulation implementing TILA, which implements the Home Ownership
         and Equity Protection Act of 1994, as amended or (b) classified and/or
         defined as a "high cost home loan" under any federal, state or local
         law, including, but not limited to, the States of Georgia or North
         Carolina;

                  (s) the information set forth in Schedule A of the Prospectus
         Supplement with respect to the Mortgage Loans is true and correct in
         all material respects; and

                  (t) no Mortgage Loan is a High Cost Loan or Covered Loan, as
         applicable (as such terms are defined in the then current Standard &
         Poor's LEVELS(R) Glossary, which is now, Version 5.6b Revised, Appendix
         E, attached hereto as Exhibit 6) and no Mortgage Loan originated on or
         after October 1, 2002 through March 6, 2003 is governed by the "Georgia
         Fair Lending Act."

                  (xxi) each Mortgage Loan was originated in accordance with the
         underwriting guidelines of the related originator;

                  (xxii) each original Mortgage has been recorded or is in the
         process of being recorded in accordance with the requirements of
         Section 2.01 of the Pooling and Servicing Agreement in the appropriate
         jurisdictions wherein such recordation is required to perfect the lien
         thereof for the benefit of the Trust Fund;

                  (xxiii) the related Mortgage File contains each of the
         documents and instruments listed in Section 2.01 of the Pooling and
         Servicing Agreement, subject to any exceptions, substitutions and
         qualifications as are set forth in such Section;

                  (xxiv) the Mortgage Loans are currently being serviced in
         accordance with accepted servicing practices;

                  (xxv) at the time of origination, each Mortgaged Property was
         the subject of an appraisal which conformed to the underwriting
         requirements of the originator of the Mortgage Loan, and the appraisal
         is in a form which was acceptable to Fannie Mae or FHLMC at the time of
         origination; and

                  (xxvi) none of the Mortgage Loans that are secured by property
         located in the State of Illinois are in violation of the provisions of
         the Illinois Interest Act.

                  It is understood and agreed that the representations and
warranties set forth in this Section 7 will inure to the benefit of the
Purchaser, its successors and assigns, notwithstanding any restrictive or
qualified endorsement on any Mortgage Note or assignment of Mortgage or the
examination of any Mortgage File. Upon any substitution for a Mortgage Loan, the
representations and warranties set forth above shall be deemed to be made by the
Mortgage Loan Seller as to any Substitute Mortgage Loan as of the date of
substitution.

                  Upon discovery or receipt of notice by the Mortgage Loan
Seller, the Purchaser or the Trustee of a breach of any representation or
warranty of the Mortgage Loan Seller set forth in this Section 7 which
materially and adversely affects the value of the interests of the Purchaser,
the Certificateholders or the Trustee in any of the Mortgage Loans delivered to
the Purchaser pursuant to this Agreement, the party discovering or receiving
notice of such breach shall give prompt written notice to the others. In the
case of any such breach of a representation or warranty set forth in this
Section 7, within 90 days from the date of discovery by the Mortgage Loan
Seller, or the date the Mortgage Loan Seller is notified by the party
discovering or receiving notice of such breach (whichever occurs earlier), the
Mortgage Loan Seller will (i) cure such breach in all material respects, (ii)
purchase the affected Mortgage Loan at the applicable Purchase Price or (iii) if
within two years of the Closing Date, substitute a qualifying Substitute
Mortgage Loan in exchange for such Mortgage Loan. The obligations of the
Mortgage Loan Seller to cure, purchase or substitute a qualifying Substitute
Mortgage Loan shall constitute the Purchaser's, the Trustee's and the
Certificateholder's sole and exclusive remedy under this Agreement or otherwise
respecting a breach of representations or warranties hereunder with respect to
the Mortgage Loans, except for the obligation of the Mortgage Loan Seller to
indemnify the Purchaser for such breach as set forth in and limited by Section
13 hereof.

                  Any cause of action against the Mortgage Loan Seller or
relating to or arising out of a breach by the Mortgage Loan Seller of any
representations and warranties made in this Section 7 shall accrue as to any
Mortgage Loan upon (i) discovery of such breach by the Mortgage Loan Seller or
notice thereof by the party discovering such breach and (ii) failure by the
Mortgage Loan Seller to cure such breach, purchase such Mortgage Loan or
substitute a qualifying Substitute Mortgage Loan pursuant to the terms hereof.

                  ARTICLE XII. REPRESENTATIONS AND WARRANTIES CONCERNING THE

on the Mortgage Loan Sellers ability to enter into this Agreement and to
consummate the transactions contemplated hereby;

                  Section 12.2. the Mortgage Loan Seller has full corporate

breach of, or constitute a default under, any of the provisions of any law,
governmental rule, regulation, judgment, decree or order binding on the Mortgage

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 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.

                  Section 17.2. 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,

                  Section 17.3. 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 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.

                  Section 17.4. 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.

                  Section 17.5. 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.

                                                       REVISED FEBRUARY 07, 2005

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.

AMENDED AND RESTATED INVESTORS’ RIGHTS AGREEMENT

     THIS AMENDED AND RESTATED INVESTORS’ RIGHTS AGREEMENT (this “Agreement”) is made as of
February 9, 2004, by and among Genomic Health, Inc., a Delaware corporation (the “Company”), and
the investors listed on Schedule A hereto, each of which is herein referred to as an “Investor.”

     WHEREAS, the Company and certain Investors are parties to that certain Amended and Restated
Investor’s Rights Agreement dated as of March 15, 2002, pursuant to which the Company granted to
such Investors certain registration, information and first offer rights with respect to the shares
of Company capital stock held by such Investors (the “Prior Agreement”), and the parties thereto
agree to amend and restate the Prior Agreement in its entirety as set forth herein; and

     WHEREAS, to induce certain other of the Investors to purchase shares of Series E Preferred
Stock from the Company and to enter into that certain Series E Preferred Stock Purchase Agreement,
dated as of the date hereof (the “Purchase Agreement”), the Company and the Investors desire to
enter into this Agreement.

     NOW, THEREFORE, in consideration of the mutual promises and covenants set forth herein, the
parties hereto further agree as follows:

     1. Registration Rights. The Company covenants and agrees as follows:

          1.1 Definitions. For purposes of this Section 1:

               (a) “Act” means the Securities Act of 1933, as amended, or any similar successor federal
statute and the rules and regulations thereunder, all as the same shall be in effect from time to
time.

               (b) “Form S-3” means such form under the Act as in effect on the date hereof or any
registration form under the Act subsequently adopted by the SEC in lieu of Form S-3 that permits
inclusion or incorporation of substantial information by reference to other documents filed by the
Company with the SEC.

               (c) “Holder” means any person owning or having the right to acquire Registrable Securities or
any assignee thereof in accordance with Section 1.12 hereof.

               (d) “1934 Act” shall mean the Securities Exchange Act of 1934, as amended, or any similar
successor federal statute and the rules and regulations thereunder, all as the same shall be in
effect from time to time.

               (e) “Qualified IPO” means the firm commitment underwritten public offering by the Company by
shares of its Common Stock pursuant to a registration statement on Form S-1 (or any successor form)
under the Securities Act which results in aggregate cash proceeds to the Company of at least
$20,000,000 (before deduction for underwriters’ discounts and commissions and expenses).

-1-

 

               (f) “Register,” “registered,” and “registration” refer to a registration effected by preparing
and filing a registration statement or similar document in compliance with the Act, and the
declaration or ordering of effectiveness of such registration statement or document.

               (g) “Registrable Securities” means (i) the Common Stock issuable or issued upon conversion of
the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Series E Preferred Stock, and (ii) any Common Stock of the Company issued as
(or issuable upon the conversion or exercise of any warrant, right or other security that is issued
as) a dividend or other distribution with respect to, or in exchange for or in replacement of the
shares referenced in (i) above, excluding in all cases, however, any Registrable Securities sold by
a person in a transaction in which his rights under this Section 1 are not assigned.

               (h) The number of shares of “Registrable Securities then outstanding” shall be determined by
the number of shares of Common Stock outstanding which are, and the number of shares of Common
Stock issuable pursuant to then exercisable or convertible securities which are exercisable or
convertible into, Registrable Securities.

               (i) “SEC” shall mean the Securities and Exchange Commission or any other federal agency at the
time administering the Act.

          1.2 Request for Registration.

               (a) If the Company shall receive at any time after six (6) months after the effective date of
the first registration statement for a public offering of securities of the Company (other than a
registration statement relating either to the sale of securities to employees of the Company
pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction under the
Act), a written request from the Holders of a majority of the Registrable Securities then
outstanding that the Company file a registration statement under the Act covering the registration
of Registrable Securities with an expected aggregate offering price to the public of at least
$10,000,000 (before deduction of underwriting discounts and commissions), then the Company shall:

                    (i) within ten (10) days of the receipt thereof, give written notice of such request to all
Holders; and

                    (ii) file as soon as practicable, and in any event within seventy-five (75) days of the
receipt of such request, a registration statement under the Act covering all Registrable Securities
that the Holders request to be registered, subject to the limitations of Section 1.2(b), within
twenty (20) days of the mailing of such notice by the Company in accordance with Section 3.5.

               (b) If the Holders initiating the registration request hereunder (“Initiating Holders”) intend
to distribute the Registrable Securities covered by their request by means of an underwriting, they
shall so advise the Company as a part of their request made pursuant to Section 1.2(a) and the
Company shall include such information in the written notice referred to in Section 1.2(a). The
underwriter or underwriters shall be selected by the Company and shall be reasonably acceptable to
a majority in interest of the Initiating Holders. In such event, the right of any Holder to
include such Holder’s Registrable Securities in such registration shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable
Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to

-2-

 

distribute their securities through such underwriting shall (together with the Company as
provided in Section 1.5(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of
this Section 1.2, if the underwriter advises the Initiating Holders in writing that marketing
factors require a limitation of the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities that would otherwise be underwritten
pursuant hereto, and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities owned by each Holder;
provided, however, that the number of shares of Registrable Securities to be included in such
underwriting shall not be reduced unless all other securities are first entirely excluded from the
underwriting.

               (c) Notwithstanding the foregoing, if the Company shall furnish to Initiating Holders a
certificate signed by the Chief Executive Officer or President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to
the Company and its stockholders for such registration statement to be filed and it is therefore
essential to defer the filing of such registration statement, the Company shall have the right to
defer such filing for a period of not more than ninety (90) days after receipt of the request of
the Initiating Holders; provided, however, that the Company may not utilize this right more than
once in any twelve (12) month period.

               (d) In addition, the Company shall not be obligated to effect, or to take any action to
effect, any registration pursuant to this Section 1.2:

                    (i) After the Company has effected two (2) registrations pursuant to this Section 1.2 and such
registrations have been declared or ordered effective;

                    (ii) During the period starting with the date sixty (60) days prior to the Company’s good
faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after
the effective date of, a registration subject to Section 1.3 hereof; provided that the Company is
actively employing in good faith all reasonable efforts to cause such registration statement to
become effective; or

                    (iii) If the Initiating Holders propose to dispose of shares of Registrable Securities that
may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 1.4 below.

          1.3 Company Registration. If (but without any obligation to do so) the Company
proposes to register (including for this purpose a registration effected by the Company for
stockholders other than the Holders) any of its Common Stock under the Act in connection with a
firm commitment underwritten public offering solely of Common Stock and solely for cash (other than
a registration relating solely to the sale of securities to participants in a Company stock plan, a
registration on any form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the Registrable
Securities, or a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities that are also being registered), the Company shall, at
such time, promptly give each Holder written notice of such registration. Upon the written request
of each Holder given within twenty (20) days after mailing of such notice by the Company in
accordance

-3-

 

with Section 3.5, the Company shall, subject to the provisions of Section 1.8, cause to be
registered under the Act all of the Registrable Securities that each such Holder has requested to
be registered.

          1.4 Form S-3 Registration. In case the Company shall receive from any Holder or
Holders a written request or requests that the Company effect a registration on Form S-3 and any
related qualification or compliance with respect to all or a part of the Registrable Securities
owned by such Holder or Holders, the Company will:

               (a) promptly give written notice of the proposed registration, and any related qualification
or compliance, to all other Holders; and

               (b) as soon as practicable, use all reasonable efforts to effect such registration and all
such qualifications and compliances as may be so requested and as would permit or facilitate the
sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as
are specified in such request, together with all or such portion of the Registrable Securities of
any other Holder or Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company; provided, however,
that the Company shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.4: (i) if Form S-3 is not available for such offering by
the Holders; (ii) if the Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable Securities and such other
securities (if any) at an aggregate price to the public (before deduction of any underwriters’
discounts or commissions) of less than $2,500,000; (iii) if the Company shall furnish to the
Holders a certificate signed by the Chief Executive Officer or President of the Company stating
that in the good faith judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at
such time, in which event the Company shall have the right to defer the filing of the Form S-3
registration statement for a period of not more than ninety (90) days after receipt of the request
of the Holder or Holders under this Section 1.4; provided, however, that the Company shall not
utilize this right more than once in any twelve (12) month period; (iv) if the Company has, within
the nine (9) month period preceding the date of such request, already effected one (1) registration
on Form S-3 for the Holders pursuant to this Section 1.4; (v) in any particular jurisdiction in
which the Company would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance; or (vi) after the
Company has effected four (4) registrations pursuant to this Section 1.4 and such registrations
have been declared or ordered effective.

               (c) Subject to the foregoing, the Company shall file a registration statement covering the
Registrable Securities and other securities so requested to be registered as soon as practicable
after receipt of the request or requests of the Holders. Registrations effected pursuant to this
Section 1.4 shall not be counted as demands for registration or registrations effected pursuant to
Sections 1.2 or 1.3, respectively.

          1.5 Obligations of the Company. Whenever required under this Section 1 to effect the
registration of any Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

               (a) Prepare and file with the SEC a registration statement with respect to such Registrable
Securities and use all reasonable efforts to cause such registration statement to become effective,
and keep such registration statement effective for a period of up to one hundred

-4-

 

eighty (180) days or until the distribution contemplated in the Registration Statement has
been completed (the “Effectiveness Period”); provided, however, that the Effectiveness Period shall
be extended for a period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of Common Stock (or other
securities) of the Company. In the event that, in the judgment of the Company, it is advisable to
suspend use of the prospectus relating to such registration statement for a discrete period of time
(a “Deferral Period”) due to pending material corporate developments or similar material events
that have not yet been publicly disclosed and as to which the Company believes public disclosure
will be prejudicial to the Company, the Company shall deliver a certified resolution of the Board
of Directors of the Company, signed by a duly authorized officer of the Company, to each Holder of
Registrable Securities covered by such registration statement to the effect of the foregoing and,
upon receipt of such certificate, such Holders agree not to dispose of such Holders’ Registrable
Securities covered by such registration or prospectus (other than in transactions exempt from the
registration requirements under the Securities Act); provided, however, that such Deferral Period
shall be no longer than 60 days. The Effectiveness Period shall be extended for a period of time
equal to such Deferral Period.

               (b) Prepare and file with the SEC such amendments and supplements to such registration
statement and the prospectus used in connection with such registration statement as may be
necessary to comply with the provisions of the Act with respect to the disposition of all
securities covered by such registration statement.

               (c) Furnish to the Holders of Registrable Securities covered by such registration statement
such numbers of copies of a prospectus, including a preliminary prospectus, and any amendment or
supplement thereto, all in conformity with the requirements of the Act, and such other documents as
they may reasonably request in order to facilitate the disposition of such Registrable Securities.

               (d) Use all reasonable efforts to register and qualify the securities covered by such
registration statement under such other securities or Blue Sky laws of such jurisdictions as shall
be reasonably requested by the Holders; provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to file a general
consent to service of process in any such states or jurisdictions.

               (e) In the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement, in usual and customary form, with the managing underwriter of such
offering. Each Holder participating in such underwriting shall also enter into and perform such
Holder’s obligations under such an agreement.

               (f) Promptly notify each Holder of Registrable Securities covered by such registration
statement at any time when a prospectus relating thereto is required to be delivered under the Act
of the happening of any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading or, if for any reason it
shall be necessary during such time period to amend or supplement the registration statement or the
prospectus in order to comply with the Securities Act, whereupon, in either case, each Holder shall
immediately cease to use such registration statement or prospectus for any purpose and, as promptly
as practicable thereafter, the Company shall prepare and file with the SEC, and furnish without

-5-

 

charge to the appropriate Holders and managing underwriters, if any, a supplement or amendment
to such registration statement or prospectus which will correct such statement or omission or
effect such compliance and such copies thereof as the Holders and any underwriters may reasonably
request.

               (g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each
securities exchange or automated quotation system on which similar securities issued by the Company
are then listed.

               (h) Provide a transfer agent and registrar for all Registrable Securities registered pursuant
hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the
effective date of such registration.

               (i) Use its reasonable efforts to furnish, at the request of the underwriter pursuant to an
underwriting agreement, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to Section 1.2, (i) an opinion,
dated such date, of the counsel representing the Company for the purposes of such registration, in
form and substance as is customarily given to underwriters in an underwritten public offering,
addressed to the underwriters, and (ii) a letter, dated such date, from the independent certified
public accountants of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering, addressed to the
underwriters.

          1.6 Furnish Information.

               (a) It shall be a condition precedent to the obligations of the Company to take any action
pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that
such Holder shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder’s Registrable Securities.

               (b) The Company shall have no obligation with respect to any registration requested pursuant
to Section 1.2 or Section 1.4 if, due to the operation of Section 1.6(a), the number of shares or
the anticipated aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated aggregate offering
price required to originally trigger the Company’s obligation to initiate such registration as
specified in Section 1.2(a) or Section 1.4(b)(ii), whichever is applicable.

          1.7 Expenses of Registration.

               (a) Except as set forth in Section 1.7(b), the Company shall bear and pay all expenses
incurred in connection with any registration, filing or qualification of Registrable Securities
with respect to the registrations pursuant to Sections 1.2, 1.3 and 1.4 hereof, including (without
limitation) all registration, filing, and qualification fees, printers’ and accounting fees, blue
sky fees and expenses, including fees and disbursements of counsel related to all blue sky matters,
fees and expenses of listing any Registrable Securities on any securities exchange or automated
quotation system on which shares of Common Stock are then listed, fees and disbursements of counsel
for the Company and the reasonable fees and disbursements of one counsel for the selling Holders
not to exceed $20,000, but excluding stock transfer taxes that may be payable by the selling
Holders and underwriting discounts and commissions relating to Registrable Securities covered by
such registration, which shall be borne by the Holders.

-6-

 

               (b) Notwithstanding Section 1.7(a), the Company shall not be required to pay for any expenses
of any registration proceeding begun pursuant to Section 1.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to
be registered (in which case all participating Holders shall bear such expenses), unless the
Holders of a majority of the Registrable Securities agree to forfeit their right to one demand
registration pursuant to Section 1.2 or one S-3 registration pursuant to Section 1.4, as
applicable; provided further, however, that if such withdrawal occurs prior to the date the
registration statement shall have become effective and at the time of such withdrawal, the Holders
have learned of a material adverse change in the financial condition, business, properties or
results of operations of the Company from that known to the Holders at the time of their request
and have withdrawn the request with reasonable promptness following disclosure by the Company of
such material adverse change, then the Holders shall not be required to pay any of such expenses
and shall retain their rights pursuant to Section 1.2 and 1.4, as applicable.

          1.8 Underwriting Requirements. In connection with any offering involving an
underwriting of shares being issued by the Company, the Company shall not be required under Section
1.3 to include any of the Holders’ securities in such underwriting unless they accept the terms of
the underwriting as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success of the offering by
the Company. If the total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is compatible with the success
of the offering, then the Company shall be required to include in the offering only that number of
such securities, including Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so included to be
apportioned pro rata among the selling stockholders according to the total amount of securities
entitled to be included therein owned by each selling stockholder or in such other proportions as
shall mutually be agreed to by such selling stockholders) but provided, however, that the number of
shares of (i) Registrable Securities, and (ii) securities of the Company (i.e., primary shares) to
be included in such underwriting shall not be reduced unless all other securities are first
entirely excluded from the underwriting; provided further that in no event shall the amount of
securities of the selling Holders included in the offering be reduced below twenty-five percent
(25%) of the total amount of securities included in such offering, unless such offering is the
initial public offering of the Company’s securities in which case the selling Holders may be
excluded if the underwriters make the determination described above. For purposes of the preceding
parenthetical concerning apportionment, for any selling stockholder that is a Holder of Registrable
Securities and that is a partnership, limited liability company or corporation, the partners,
retired partners, members and stockholders of such Holder, or the estates and family members of any
such partners and retired partners or members and any trusts for the benefit of any of the
foregoing persons and affiliates of such Holder shall be deemed to be a single “selling
stockholder,” and any pro rata reduction with respect to such “selling stockholder” shall be based
upon the aggregate amount of Registrable Securities owned by all entities and individuals included
in such “selling stockholder,” as defined in this sentence.

          1.9 Delay of Registration. No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any such registration as the result of any controversy
that might arise with respect to the interpretation or implementation of this Section 1.

-7-

 

          1.10 Indemnification. In the event any Registrable Securities are included in a
registration statement under this Section 1:

               (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder,
the officers, directors, partners of each Holder, any underwriter (as defined in the Act) for such
Holder and each person. if any, who controls such Holder or underwriter within the meaning of the
Act or the 1934 Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Act, the 1934 Act or other federal or state securities law,
insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out
of or are based upon any of the following statements, omissions or violations (collectively, a
“Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the statements therein
not misleading, or (iii) any violation or alleged violation by the Company of the Act, the 1934
Act, any state securities law or any rule or regulation promulgated under the Act, the 1934 Act or
any state securities law; and the Company will reimburse, as incurred, each such Holder, officer,
director, partner, underwriter or controlling person, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained in this Section
1.10(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is based upon a
Violation that occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder, officer, director,
partner, underwriter or controlling person.

               (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the
Company, each of its directors, each of its officers who has signed the registration statement,
each person, if any, who controls the Company within the meaning of the Act, any underwriter, any
other Holder selling securities in such registration statement and any officer, director or
controlling person of any such Holder, against any losses, claims, damages, or liabilities (joint
or several) to which any of the foregoing persons may become subject, under the Act, the 1934 Act
or other federal or state securities law insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses reasonably incurred
by any person intended to be indemnified pursuant to this Section 1.10(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this Section 1.10(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably withheld; provided
further, that, in no event shall any indemnity under this Section 1.10(b) exceed the aggregate
gross proceeds from the sale of the Registrable Securities received by such Holder from the shares
sold by such Holder in the offering in question, except in the case of willful fraud by such
Holder.

               (c) Promptly after receipt by an indemnified party under this Section 1.10 of notice of the
commencement of any action (including any governmental action), such indemnified

-8-

 

party will, if a claim in respect thereof is to be made against any indemnifying party under
this Section 1.10, deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to
assume the defense thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties that may be represented
without conflict by one counsel) shall have the right to retain one separate counsel, with the fees
and expenses to be paid by the indemnifying party, if representation of such indemnified party by
the counsel retained by the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party represented by such counsel
in such proceeding. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action, if prejudicial to its ability to defend
such action, shall relieve such indemnifying party of any liability to the indemnified party under
this Section 1.10, but the omission so to deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise than under this
Section 1.10. An indemnifying party shall not, without the prior written consent of the
indemnified parties, settle, compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which indemnification may be
sought hereunder by such indemnified parties (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or consent includes a
release of such indemnified party reasonably acceptable to such indemnified party from all
liability arising out of such claim, action, suit or proceeding.

               (d) If the indemnification provided for in this Section 1.10 is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim,
damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by a Holder under this Section 1.10(d) exceed the
net proceeds from the offering received by such Holder, except in the case of willful fraud by such
Holder. The relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access
to information, and opportunity to correct or prevent such statement or omission.

               (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and
contribution contained in the underwriting agreement entered into in connection with the
underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.

               (f) The obligations of the Company and Holders under this Section 1.10 shall survive the
completion of any offering of Registrable Securities in a registration statement under this Section
1, and otherwise.

     1.11 Reports Under Securities Exchange Act of 1934. With a view to making available
to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or

-9-

 

regulation of the SEC that may at any time permit a Holder to sell securities of the Company
to the public without registration or pursuant to a registration on Form S-3, the Company agrees
to:

               (a) make and keep public information available, as those terms are understood and defined in
SEC Rule 144, at all times after ninety (90) days after the effective date of the first
registration statement filed by the Company for the offering of its securities to the general
public;

               (b) take such action, including the voluntary registration of its Common Stock under Section
12 of the 1934 Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal
year in which the first registration statement filed by the Company for the offering of its
securities to the general public is declared effective;

               (c) file with the SEC in a timely manner all reports and other documents required of the
Company under the Act and the 1934 Act; and

               (d) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith
upon request (i) a written statement by the Company that it has complied with the reporting
requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the
first registration statement filed by the Company), the Act and the 1934 Act (at any time after it
has become subject to such reporting requirements), or that it qualifies as a registrant whose
securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of
the most recent annual or quarterly report of the Company and such other reports and documents so
filed by the Company, and (iii) such other information as may be reasonably requested in availing
any Holder of any rule or regulation of the SEC that permits the selling of any such securities
without registration or pursuant to such form.

          1.12 Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities pursuant to this Section 1 may be assigned (but only with all related
obligations) by (a) a Holder to a transferee or assignee of such securities who, after such
assignment or transfer, holds at least 250,000 shares of such Holder’s Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends, combinations and other
recapitalizations and including for purposes of such calculation the shares of Common Stock then
issuable upon conversion of Preferred Stock), (b) any Holder who transfers all of its Registrable
Securities, or (c) a Holder to its shareholders, partners, members, former partners or former
members (or their estates), subsidiaries or affiliates; provided, however: (i) the Company is,
within a reasonable time after such transfer, furnished with written notice of the name and address
of such transferee or assignee and the securities with respect to which such registration rights
are being assigned; (ii) such transferee or assignee agrees in writing to be bound by and subject
to the terms and conditions of this Agreement; and (iii) such assignment shall be effective only if
immediately following such transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act. For the purposes of determining the number of shares of
Registrable Securities held by a transferee or assignee, the holdings of transferees and assignees
of a partnership or limited liability company who are partners or retired partners of such
partnership or members of such limited liability company (including spouses and ancestors, lineal
descendants and siblings of such partners or members or spouses who acquire Registrable Securities
by gift, will or intestate succession) shall be aggregated together and with the partnership or
limited liability company, as the case may be; provided that all assignees and transferees who
would not qualify individually for assignment of registration rights

-10-

 

shall have a single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under this Section 1. For purposes of this Agreement, the terms
“affiliates” or “affiliated” shall mean, which respect to any person or entity, any person or
entity that, directly or indirectly, controls or is controlled by or is under common control with
such person or entity. For the purposes of the preceding sentence, the term “control” shall mean
the possession, directly or indirectly, through one or more intermediaries in the case of any
person or entity, of the power or authority, through ownership of voting securities, by contract or
otherwise, to direct the management, activities or policies of the person or entity.

          1.13 Limitations on Subsequent Registration Rights. From and after the date of this
Agreement, the Company shall not, without the prior written consent of the Holders of a majority of
the Registrable Securities then outstanding, enter into any agreement with any holder or
prospective holder of any securities of the Company that would allow such holder or prospective
holder (a) to include such securities in any registration filed under Section 1.2 hereof, unless
under the terms of such agreement, such holder or prospective holder may include such securities in
any such registration only to the extent that the inclusion of such holder’s securities will not
reduce the amount of the Registrable Securities of the Holders that is included or (b) to make a
demand registration that could result in such registration statement being declared effective prior
to the earlier of either of the dates set forth in Section 1.2(a) or within one hundred twenty
(120) days of the effective date of any registration effected pursuant to Section 1.2.

          1.14 “Market Stand-Off” Agreement. Each Holder hereby agrees that during the period
of duration specified by the Company and an underwriter of common stock or other securities of the
Company following the date of the first sale to the public pursuant to a registration statement of
the Company filed under the Act, it shall not, to the extent requested by the Company and such
underwriter, (i) lend, offer, pledge, sell, contract to sell (including, without limitation, any
short sale), sell any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock, other than to donees who agree to be similarly bound, or (ii) enter
into any swap or other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock, whether any such transaction described in
clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise, except for securities to be sold to such underwriter pursuant to such
registration statement; provided, however, that:

               (a) such agreement shall not be applicable to shares of common stock of the Company acquired
by the Holders in a public offering or in an open market transaction;

               (b) such agreement shall be applicable only to the first such registration statement of the
Company that covers common stock (or other securities) to be sold on its behalf to the public in an
underwritten offering;

               (c) such market stand-off time period shall not exceed one hundred eighty (180) days; and

               (d) all of the officers, directors and all other persons with registration rights (whether or
not pursuant to this Agreement) enter into similar agreements.

-11-

 

     In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions
with respect to the Registrable Securities of each Holder (and the shares or securities of every
other person subject to the foregoing restriction) until the end of such period.

     Notwithstanding the foregoing, the obligations described in this Section 1.14 shall not apply
to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar
forms that may be promulgated in the future, or a registration relating solely to a Rule 145
transaction under the Act.

          1.15 Limitations. The obligations described in Section 1.14(a) shall apply only if
all officers and directors of the Company and all other persons with registration rights (whether
or not pursuant to this Agreement) enter into similar agreements. If the Company or the
underwriter of any public offering of the Company’s securities waive or terminate any standoff or
lockup restrictions imposed on any holder of securities of the Company, then such waiver or
termination shall be granted to all Holders subject to standoff or lockup restrictions pro rata
based on the number of shares of Common Stock beneficially held by such holder and the Holders.
From and after the date of this Agreement, the Company shall use all reasonable efforts to ensure
that all holders of capital stock of the Company agree to be bound by terms substantially similar
to those set forth in Section 1.14.

          1.16 Transferees Bound. Each Holder agrees that prior to the Company’s initial public
offering it will not transfer securities of the Company unless each transferee agrees in writing to
be bound by all of the provisions of Section 1.14. 

          1.17 Termination of Registration Rights. The right of any Holder to request
registration or inclusion in any registration pursuant to Section 1.2, Section 1.3 or Section 1.4
shall terminate on the earlier of (a) five (5) years following the consummation of a Qualified IPO,
or (b) on the consummation of a Qualified IPO if all shares of Registrable Securities held or
entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during
any 90-day period, or on such date after the consummation of a Qualified IPO as all shares of
Registrable Securities held or entitled to be held upon conversion by such Holder may immediately
be sold under Rule 144 during any 90 day period; provided, however, that the provisions of this
subsection (b) shall not apply to any Holder who owns more than one percent (1%) of the Company’s
outstanding stock until such time as such Holder owns less than one percent (1%) of the outstanding
stock of the Company.

     2. Covenants of the Company.

          2.1 Delivery of Financial Statements. The Company shall deliver to each Major

and fairly present the financial condition of the Company and its results of operations for the
period specified, subject to year-end audit adjustment;

               (f) such other information relating to the financial condition, business, prospects or
corporate affairs of the Company as the Investor or any assignee of the Investor may from time to
time request, provided, however, that the Company shall not be obligated under this Section 2.1 to
provide information which it reasonably considers to be a trade secret or similar confidential
information;

               (g) The term “Major Investor” means a person or entity that, together with its affiliates,
holds at least 700,000 shares (subject to appropriate adjustment for stock splits, stock dividends,
combinations or other recapitalizations) of Common Stock (including for this purpose shares
issuable upon conversion of outstanding Preferred Stock).

          2.2 Inspection. The Company shall permit each Major Investor, at such Major
Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account
and records and to discuss the Company’s affairs, finances and accounts with its officers, all at
such reasonable times as may be requested by the Major Investor; provided, however, that the
Company shall not be obligated pursuant to this Section 2.2 to provide access to any information
that it reasonably considers to be a trade secret or similar confidential information.

          2.3 Termination of Information and Inspection Covenants. The covenants set forth in
Section 2.1 and Section 2.2 shall terminate as to Investors and be of no further force or effect
when the sale of securities pursuant to a registration statement filed by the Company under the Act
in connection with the firm commitment underwritten offering of its securities to the general
public is consummated or when the Company first becomes subject to the periodic reporting
requirements of Sections 12(g) or 15(d) of the 1934 Act, whichever event shall first occur.

          2.4 Right of First Offer. Subject to the terms and conditions specified in this
Section 2.4, the Company hereby grants to each Investor owning at least 700,000 shares of Preferred
Stock (each a “Significant Investor”) a right of first offer with respect to future sales by the
Company of its Shares (as hereinafter defined).

-13-

 

     Each time the Company proposes to offer any shares of, or securities convertible into or
exercisable for any shares of, any class of its capital stock (“Shares”), the Company shall first
make an offering of such Shares to each Significant Investor in accordance with the following
provisions:

               (a) The Company shall deliver a notice by certified mail (“Notice”) to the Significant
Investors stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares
to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such Shares.

               (b) Within 15 calendar days after delivery of the Notice, the Significant Investor may elect
to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of
such Shares that equals the proportion that the number of shares of Common Stock issued and held,
or issuable upon conversion of the Preferred Stock then held, by such Significant Investor bears to
the total number of shares of Common Stock of the Company then outstanding (assuming full
conversion and exercise of all convertible or exercisable securities). The Company shall promptly,
in writing, inform each holder of Preferred Stock that is a Significant Investor that purchases all
the shares available to it (“Fully-Exercising Investor”) of any other Significant Investor’s
failure to do likewise. During the ten-day period commencing after such information is given, each
Fully-Exercising Investor shall be entitled to obtain that portion of the Shares not subscribed for
by the Significant Investors that is equal to the proportion that the number of shares of Preferred
Stock then held (or common stock issued as a result of conversion of shares of Preferred Stock and
held) by such Fully-Exercising Investor bears to the total number of shares of Preferred Stock then
held (or common stock issued as a result of conversion of shares of Preferred Stock then held) by
all Fully-Exercising Investors who wish to purchase some of the unsubscribed shares.

               (c) If all Shares referred to in the Notice are not elected to be obtained as provided in
Section 2.4(b) hereof, the Company may, during the 30-day period following the expiration of the
period provided in Section 2.4(b) hereof, offer the remaining unsubscribed portion of such Shares
to any person or persons at a price not less than, and upon terms no more favorable to the offeree
than those specified in the Notice. If the Company does not enter into an agreement for the sale
of the Shares within such period, or if such agreement is not consummated within 30 days of the
execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall
not be offered unless first reoffered to the Significant Investors in accordance herewith.

               (d) The right of first offer in this Section 2.4 shall not be applicable (i) to the issuance
or sale of Common Stock (or options therefor) to employees, directors, consultants or advisors of
the Company (for the primary purpose of soliciting or retaining their employment or services), (ii)
to or after consummation of a bona fide, firmly underwritten public offering of shares of common
stock, registered under the Act pursuant to a registration statement on Form S-1, (iii) the
issuance of securities pursuant to the conversion or exercise of convertible or exercisable
securities, (iv) the issuance of securities in connection with a bona fide business acquisition of
or by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or
otherwise, (v) the issuance of stock, warrants or other securities or rights with the approval of
the Board of Directors to persons or entities with which the Company has business relationships or
(vi) to the sale and issuance by the Company of up to ten million six hundred thirty-eight thousand
two hundred ninety eight (10,638,298) shares of Series E Preferred Stock pursuant to the Purchase
Agreement. Investors who are party to the Prior Agreement hereby agree to waive notice and
observance of the right of first offer set forth in Section 2.4 of the Prior Agreement.

-14-

 

               (e) The right of first offer set forth in this Section 2.4 may not be assigned or transferred,
except that (i) such right is assignable by each Investor to any wholly owned subsidiary or parent
of, or to any corporation or entity that is, within the meaning of the Act, controlling, controlled
by or under common control with, any such Investor, and (ii) such right is assignable between and
among any of the Investors.

          2.5 Key-Man Insurance; Fire and Casualty Insurance. The Company has as of the date
hereof or shall within 90 days of the date hereof use all reasonable efforts to obtain from
financially sound and reputable insurers term life insurance on the lives of each of Randal W.
Scott, Joffre B. Baker and Steven Shak in the amount or amounts decided in accordance with policies
adopted by the Company’s Board of Directors. The Company will cause to be maintained the term life
insurance required by this Section 2.5 hereof, except as otherwise decided in accordance with
policies adopted by the Company’s Board of Directors. Such policies shall name the Company as loss
payee and shall not be cancelable by the Company without prior approval of the Board of Directors.
The Company shall also within 90 days of the date hereof use all reasonable efforts to obtain fire
and casualty insurance policies, with extended coverage, sufficient in amount (subject to
reasonable deductibles) to allow it to replace any of its properties that might be damaged or
destroyed.

schedule: twenty-five percent (25%) of the Stock shall vest, and the Company Right shall lapse

such status. In addition, the Company shall submit to the Investors and to the Internal Revenue
Service any reports that may be required under Section 1202(d)(1)(C) of the Code and any related
Treasury Regulations. In addition, within ten days after any Investor has delivered to the Company
a written request therefor, the Company shall deliver to such Investor a written statement
informing the Investor whether, in the Company’s good-faith judgment after a reasonable
investigation, such Investor’s interest in the Company constitutes “qualified small business stock”
as defined in Section 1202(c) of the Code. The Company’s obligation to furnish a written statement
pursuant to this Section 2.10 shall continue notwithstanding the fact that a class of the Company’s
stock may be traded on an established securities market.
