     For federal income tax purposes, the Class CE-2 Certificates shall
represent a "regular interest" in REMIC CE-2 entitled to 100% of the payments on

Certificates shall represent (i) the right to receive all distributions with
respect to the REMIC Regular Interests represented by the REMIC CE-1 CE-1
Interest and the REMIC IO IO Interest, (ii) the obligation to pay amounts in

(1)  For any Distribution Date, the interest rate for these interests shall be a
     per annum rate (but not less than zero) equal to the product of (i) the
     weighted average of the interest rates on the SWAP REMIC Regular Interests
     (other than the Class SW-CE2 Interest) for such Distribution Date and (ii)
     a fraction the numerator of which is 30 and the denominator of which is the
     actual number of days in the Interest Accrual Period for the Class A-1
     Certificates, provided however, that for any Distribution Date on which the
     Class LT1-IO Interest is entitled to a portion of interest accruals on a
     SWAP REMIC Regular Interest ending with a designation "A" as described in
     footnote 11 below, such weighted average shall be computed by first
     subjecting the rate on such SWAP REMIC Regular Interest to a cap equal to
     Swap LIBOR for such Distribution Date.

(2)  For each Distribution Date, the interest rate for the Class LT1-IB Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "1" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the Class A-1 Certificates, provided,
     however, that for any Distribution Date on which the Class LT1-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(3)  For each Distribution Date, the interest rate for the Class LT1-IIB
     Interest shall be a per annum rate equal to the product of (i) the weighted
     average of the interest rates on the SWAP REMIC Regular Interests beginning
     with the designation "2" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the Class A-1 Certificates, provided,
     however, that for any Distribution Date on which the Class LT1-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(4)  The initial principal amount of these interests shall be an amount equal to
     25% of the initial principal amount of the related certificates.

(5)  The initial principal amount of this interest shall be an amount equal to
     the excess of (i) 50% of the aggregate Cut-off Date Principal Balance of
     the Mortgage Loans over (ii) the aggregate initial principal amount of the
     Marker I Interests.

(6)  The initial principal amount of the Class LT1-IA Interest shall equal 0.05%
     of the excess of (i) the aggregate Cut-off Date Principal Balance of Loan
     Group I over (ii) the aggregate of the initial principal amount of the
     Class A-1 Certificates.

(7)  The initial principal amount of the Class LT1-IB Interest shall equal 0.05%
     of the aggregate Cut-off Date Principal Balance of Loan Group I.

(8)  The initial principal amount of the Class LT1-IIA Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of
     Loan Group II over (ii) the aggregate of the initial principal amount of
     the Class A-2 Certificates.

(9)  The initial principal amount of the Class LT1-IIB Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Loan Group II.

(10) The initial principal amount of the Class LT1-X2 Interest shall equal the
     excess of (i) 50% of the aggregate Cut-off Date Principal Balance of the
     Mortgage Loans over (ii) the aggregate initial principal amount of the
     Marker II Interests.

(11) The Class LT1-IO Interest is an interest-only class that does not have a
     principal balance. For only those Distribution Dates listed in the first
     column of the table below, the Class LT1-IO Interest shall be entitled to
     interest accrued on the SWAP REMIC Regular Interest listed in the second
     column below at a per annum rate equal to the excess, if any, of (i) the
     interest rate for such SWAP REMIC Regular Interest for such Distribution
     Date over (ii) Swap LIBOR for such Distribution Date.

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

     Section 2.01 Conveyance of Mortgage Loans.

     The Depositor, concurrently with the execution and delivery hereof, does
hereby transfer, assign, set over and otherwise convey to the Trustee, on behalf
of the Trust, without recourse, for the benefit of the Certificateholders, all
the right, title and interest of the Depositor, including any security interest
therein for the benefit of the Depositor, in and to (i) each Mortgage Loan

(ii) property which secured each such Mortgage Loan and which has been acquired
by foreclosure or deed in lieu of foreclosure; (iii) its interest in any
insurance policies in respect of the Mortgage Loans; (iv) all proceeds of any of

or the Servicer after the Cut-off Date with respect to the Mortgage Loans.

     The Depositor, the Seller, the Servicer and the Trustee hereto agree and
understand that it is not intended that any Mortgage Loan be included in the
Trust Fund that is, without limitation, a "High-Cost Home Loan" as defined by
the Home Ownership and Equity Protection Act of 1994 or any other applicable
anti-predatory lending laws, including but not limited to (i) a "High-Cost Home
Loan" as defined in the New Jersey Home Ownership Act effective November 27,
2003; (ii) a "High-Cost Home Loan" as defined in the New Mexico Home Loan
Protection Act effective January 1, 2004; (iii) a "High-Cost Home Loan" as
defined in the Massachusetts Predatory Home Loan Practices Act effective
November 7, 2004 (iv) a "High-Cost Home Loan" as defined by the Indiana High
Cost Home Loan Law effective January 1, 2005; or (v) a "High-Cost Home Loan" as
defined by the Illinois High-Risk Home Loan Act effective January 1, 2004.

     In connection with such transfer and assignment, the Seller, on behalf of
the Depositor, does hereby deliver to, and deposit with the Custodian, the
following documents or instruments with respect to each Mortgage Loan (a
"Mortgage File") so transferred and assigned:

               (i) the original Mortgage Note including any riders thereto,
endorsed either (A) in blank or (B) in the following form: "Pay to the order of
LaSalle Bank National Association, as Trustee for the C-BASS Mortgage Loan
Asset-Backed Certificates, Series 2007-CB4, without recourse," or with respect
to any lost Mortgage Note, an original Lost Note Affidavit, together with a copy
of the related Mortgage Note;

               (ii) the original Mortgage including any riders thereto, with
evidence of recording thereon, and the original recorded power of attorney, if
the Mortgage was executed pursuant to a power of attorney, with evidence of
recording thereon or, if such Mortgage or power of attorney has been submitted
for recording but has not been returned from the applicable public recording
office, has been lost or is not otherwise available, a copy of such Mortgage or
power of attorney, as the case may be, certified to be a true and complete copy
of the original submitted for recording;

                                       63

<PAGE>

               (iii) an original Assignment of Mortgage, in form and substance
acceptable for recording. The Mortgage shall be assigned either (A) in blank or
(B) to "LaSalle Bank National Association, as Trustee for the C-BASS Mortgage
Loan Asset-Backed Certificates, Series 2007-CB4, without recourse";

               (iv) an original or a certified copy of any intervening
assignment of Mortgage showing a complete chain of assignments;

               (v) the original or a certified copy of lender's title insurance
policy; and

               (vi) the original or copies of each assumption, modification,
written assurance or substitution agreement, if any.

     The Custodian agrees to execute and deliver to the Depositor on or prior to
the Closing Date an acknowledgment of receipt of the original Mortgage Note
(with any exceptions noted), substantially in the form attached as Exhibit F-3
hereto.

     If any of the documents referred to in Section 2.01(ii), (iii) or (iv)
above has as of the Closing Date been submitted for recording but either (x) has
not been returned from the applicable public recording office or (y) has been
lost or such public recording office has retained the original of such document,
the obligations of the Seller to deliver such documents shall be deemed to be
satisfied upon (1) delivery to the Custodian no later than the Closing Date, of
a copy of each such document certified by the Seller in the case of (x) above or
the applicable public recording office in the case of (y) above to be a true and
complete copy of the original that was submitted for recording and (2) if such
copy is certified by the Seller, delivery to the Custodian, promptly upon
receipt thereof of either the original or a copy of such document certified by
the applicable public recording office to be a true and complete copy of the
original. The Seller shall deliver or cause to be delivered to the Custodian
promptly upon receipt thereof any other documents constituting a part of a
Mortgage File received with respect to any Mortgage Loan, including, but not
limited to, any original documents evidencing an assumption or modification of
any Mortgage Loan.

     Upon discovery or receipt of notice of any materially defective document
in, or that a document is missing from, a Mortgage File, the Seller shall have
120 days to cure such defect or 150 days following the Closing Date, in the case
of missing Mortgages or Assignments or deliver such missing document to the
Trustee or the Custodian. If the Seller does not cure such defect or deliver
such missing document within such time period, and such failure to deliver or
cure, as applicable, would have a material and adverse effect on
Certificateholders, the Seller shall either repurchase or substitute for such
Mortgage Loan in accordance with Section 2.03.

     The Servicer shall cause the Assignments of Mortgage which were delivered
in blank to be completed and shall cause all Assignments referred to in Section
2.01(iii) hereof and, to the extent necessary, in Section 2.01(iv) hereof to be
recorded at the Servicer's expense and of no cost to the Trust Fund; provided,
however, the Servicer need not cause to be recorded any Assignment which relates
to a Mortgage Loan in any jurisdiction under the laws of which, as evidenced by
an Opinion of Counsel delivered by the Servicer to the Trustee and the Rating
Agencies, the recordation of such assignment is not necessary to protect the
Trustee's interest, on behalf of the Trust, in the related Mortgage Loan. The
Servicer shall be required to deliver such assignments for recording within 30
days of the Closing Date. The Servicer shall furnish the Custodian with a copy
of each assignment of Mortgage submitted for recording. In the event that any
such Assignment is lost or returned unrecorded because of a defect therein, the
Servicer shall promptly have a substitute Assignment prepared or have such
defect cured, as

                                       64

<PAGE>

the case may be, and thereafter cause each such Assignment to be duly recorded.
In the event that any Mortgage Note is endorsed in blank as of the Closing Date,
promptly following the Closing Date the Servicer shall cause to be completed
such endorsements "Pay to the order of LaSalle Bank National Association, as
Trustee for the C-BASS Mortgage Loan Asset-Backed Certificates, Series 2007-CB4,
without recourse."

     In the event that any Assignments of Mortgage is not recorded or is
improperly recorded (as a result of actions taken or not taken by a person other
than the Servicer), neither the Servicer nor the Trustee shall have any
liability for its failure to receive notices related to such Assignment of
Mortgage.

     The Depositor herewith delivers to the Trustee executed copies of the
Mortgage Loan Purchase Agreement.

     Section 2.02 Acceptance by Trustee.

     The Trustee acknowledges the Custodian's receipt of, subject to the
provisions of Section 2.01 and subject to the review described below and any
exceptions noted on the exception report described in the next paragraph below,
the documents referred to in Section 2.01 above and all other assets included in
the definition of "Trust Fund" and declares that the Custodian holds and will
hold such documents and the other documents delivered to it constituting a
Mortgage File, and that the Custodian holds or will hold all such assets and
such other assets included in the definition of "Trust Fund" in trust for the
exclusive use and benefit of all present and future Certificateholders.

     The Custodian pursuant to the terms of the Custodial Agreement shall review
each Mortgage File within 60 days after the Closing Date (or, with respect to
any document delivered after the Startup Day, within 60 days of receipt and with
respect to any Qualified Substitute Mortgage, within 60 days after the
assignment thereof) and the Custodian shall certify in substantially the form
attached hereto as Exhibit F-1 that, as to each Mortgage Loan listed in the
Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any
Mortgage Loan specifically identified in the exception report annexed thereto as
not being covered by such certification), (i) all documents required to be
delivered to it pursuant to Section 2.01 of this Agreement are in its
possession, (ii) such documents have been reviewed by it and have not been
mutilated, damaged or torn and relate to such Mortgage Loan and (iii) based on
its examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule that corresponds to items (1), (2), (3), (5), (13) and
(26) (in the case of (26), only as to whether there is a prepayment penalty) of
the Mortgage Loan Schedule accurately reflects information set forth in the
Mortgage File. It is herein acknowledged that, in conducting such review, the
Custodian is under no duty or obligation to inspect, review or examine any such
documents, instruments, certificates or other papers to determine that they 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.

     Prior to the first anniversary date of this Agreement the Custodian shall
deliver to the Depositor and the Servicer a final certification in the form
annexed hereto as Exhibit F-2 evidencing the completeness of the Mortgage Files,
with any applicable exceptions noted thereon.

     If in the process of reviewing the Mortgage Files and making or preparing,
as the case may be, the certifications referred to above, the Custodian finds
any document or documents constituting a part of a Mortgage File to be missing
or defective in any material respect, at the conclusion of its review the
Custodian shall so notify the Seller, the Depositor and the Servicer. In
addition, upon the discovery by the Seller, Depositor, the Trustee or the
Servicer (or upon receipt by the Trustee of written notification of such breach)
of a breach of any of the representations and warranties made by the Seller in
the related

                                       65

<PAGE>

Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which
materially adversely affects such Mortgage Loan or the interests of the related
Certificateholders in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties.

     The Depositor and the Trustee intend that the assignment and transfer
herein contemplated constitute a sale of the Mortgage Loans and the Related
Documents, conveying good title thereto free and clear of any liens and
encumbrances, from the Depositor to the Trustee and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee, on behalf
of the Trust, a first priority perfected security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and the
Related Documents, and that this Agreement shall constitute a security agreement
under applicable law.

     The Trustee is hereby directed to execute, deliver and perform its
obligations Supplemental Interest Trust Trustee under the Swap Agreement on the
Closing Date and thereafter on behalf of the Supplemental Interest Trust for the
benefit of the Holders of the Adjustable Rate Certificates. The Seller, the
Servicer, the Depositor and the Holders of the Adjustable Rate Certificates by
acceptance of their Certificates acknowledge and agree that the Trustee shall
execute, deliver and perform its obligations under the Swap Agreement and shall
do so solely in its capacity as Trustee of the Supplemental Interest Trust and
not in its individual capacity. The Trustee shall not, individually or
personally, have any liability to perform any covenant either express or implied
contained in the Swap Agreement and under no circumstance shall the Trustee be
personally liable for the payment of any amounts payable by or on behalf of the
Supplemental Interest Trust under the Swap Agreement or expenses by or on behalf
of the Supplemental Interest Trust or be liable for the breach or failure of any
obligation, representation, warranty or covenant made or undertaken by or on
behalf of the Supplemental Interest Trust under the Swap Agreement.

     Section 2.03 Repurchase or Substitution of Mortgage Loans by the Seller.

          (a) Upon discovery or receipt from the Custodian of written notice of
any materially defective document in, or that a document is missing from, a
Mortgage File or of the breach by the Seller of any representation, warranty or
covenant under the Mortgage Loan Purchase Agreement or in Section 2.04 in
respect of any Mortgage Loan which materially adversely affects the value of
such Mortgage Loan or the interest therein of the Certificateholders, the
Trustee (or the Custodian, as applicable) shall promptly notify the Seller, the
Servicer and the Trustee of such defect, missing document or breach and request
that the Seller deliver such missing document or cure such defect or breach
within 120 days or 150 days following the Closing Date, in the case of missing
Mortgages or Assignments from the date the Seller was notified of such missing
document, defect or breach, and if the Seller does not deliver such missing
document or cure such defect or breach in all material respects during such
period, and such missing document, defect or breach will have a material and
adverse effect on the Certificateholders, the Trustee shall enforce the Seller's
obligation under the Mortgage Loan Purchase Agreement and inform the Seller of
its obligation to repurchase such Mortgage Loan from the Trust Fund at the
Purchase Price on or prior to the Determination Date following the expiration of
such 120 day period (subject to Section 2.03(e)); provided that, in connection
with any such breach that is susceptible to cure but that could not reasonably
have been cured within such 120 day or 150 day period, if the Seller shall have
commenced to cure such breach within such 120 day or 150 day period, the Seller
shall be permitted to proceed thereafter diligently and expeditiously to cure
the same within 120 days. The Purchase Price for the repurchased Mortgage Loan
shall be deposited in the Collection Account, and the Custodian, upon receipt of
written certification from the Servicer of such deposit, shall release to the
Seller the related Mortgage

                                       66

<PAGE>

File and shall execute and deliver such instruments of transfer or assignment,
in each case without recourse, representation or warranty, as the Seller shall
furnish to it and as shall be necessary to vest in the Seller any Mortgage Loan
released pursuant hereto and neither the Trustee nor the Custodian shall have
further responsibility with regard to such Mortgage File. In lieu of
repurchasing any such Mortgage Loan as provided above, the Seller may cause such
Mortgage Loan to be removed from the Trust Fund (in which case it shall become a
Defective Mortgage Loan) and substitute one or more Eligible Substitute Mortgage
Loans in the manner and subject to the limitations set forth in Section 2.03(d).
In addition to the foregoing, in the case of a breach of the Seller's
representation set forth in Section 3.01(6) of the Mortgage Loan Purchase
Agreement, the Seller shall reimburse the Trust for all costs or damages
incurred by the Trust as a result of the violation of such law (such amount, the
"Reimbursement Amount"). The Reimbursement Amount shall be delivered to the
Servicer for deposit into the Collection Account within 10 days from the date
the Seller was notified by the Trustee of the amount of such costs and damages.
It is understood and agreed that the obligation of the Seller to pay the
Reimbursement Amount and to either cure or repurchase (or substitute for) any
Mortgage Loan as to which a document is missing, a material defect in a
constituent document exists or as to which such a breach has occurred and is
continuing shall constitute the sole remedy against the Seller respecting such
omission, defect or breach available to the Trustee and the Trustee on behalf of
the Certificateholders.

          (b) [Reserved].

          (c) Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of any representation, warranty
or covenant of the Servicer set forth in Section 2.05 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Servicer shall cure such breach in all material respects.

          (d) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Defective Mortgage Loan for which the Seller substitutes an Eligible
Substitute Mortgage Loan or Loans, such substitution shall be effected by the
Seller delivering to the Custodian for such Eligible Substitute Mortgage Loan or
Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such
other documents and agreements, with all necessary endorsements thereon, as are
required by Section 2.01, together with an Officer's Certificate providing that
each such Eligible Substitute Mortgage Loan satisfies the definition thereof and
specifying the Substitution Adjustment Amount (as described below), if any, in
connection with such substitution. The Custodian shall acknowledge receipt for
such Eligible Substitute Mortgage Loan or Loans and, within ten Business Days
thereafter, shall review (or cause the Custodian to review) such documents as
specified in Section 2.02 and deliver (or cause the Custodian to deliver) to the
Servicer, with respect to such Eligible Substitute Mortgage Loan or Loans, a
certification substantially in the form attached hereto as Exhibit F-1, with any
applicable exceptions noted thereon. Within one year of the date of
substitution, the Trustee shall deliver (or cause the Custodian to deliver) to
the Servicer a certification substantially in the form of Exhibit F-2 hereto
with respect to such Eligible Substitute Mortgage Loan or Loans, with any
applicable exceptions noted thereon. Monthly Payments due with respect to
Eligible Substitute Mortgage Loans in the month of substitution are not part of
the Trust Fund and will be retained by the Seller. For the month of
substitution, distributions to Certificateholders will reflect the collections
and recoveries in respect of such Defective Mortgage Loan in the Collection
Period preceding the month of substitution and the Depositor or the Seller, as
the case may be, shall thereafter be entitled to retain all amounts subsequently
received in respect of such Defective Mortgage Loan. The Seller shall give or
cause to be given written notice to the Certificateholders that such
substitution has taken place, shall amend the Mortgage Loan Schedule to reflect
the removal of such Defective Mortgage Loan from the terms of this Agreement and
the substitution of the Eligible Substitute Mortgage Loan or Loans and shall
deliver a copy of such

                                       67

<PAGE>

amended Mortgage Loan Schedule to the Trustee. Upon such substitution, such
Eligible Substitute Mortgage Loan or Loans shall constitute part of the Mortgage
Pool and shall be subject in all respects to the terms of this Agreement and, in
the case of a substitution effected by the Seller, the Mortgage Loan Purchase
Agreement, including, in the case of a substitution effected by the Seller all
applicable representations and warranties thereof included in the Mortgage Loan
Purchase Agreement and all applicable representations and warranties thereof set
forth in Section 2.04, in each case as of the date of substitution.

     For any month in which the Seller substitutes one or more Eligible
Substitute Mortgage Loans for one or more Defective Mortgage Loans, the Servicer
will determine the amount (the "Substitution Adjustment Amount"), if any, by
which the aggregate Purchase Price of all such Defective Mortgage Loans exceeds
the aggregate, as to each such Eligible Substitute Mortgage Loan, of the
principal balance thereof as of the date of substitution, together with one
month's interest on such principal balance at the applicable Net Mortgage
Interest Rate. On the date of such substitution, the Seller will deliver or
cause to be delivered to the Servicer for deposit in the Collection Account an
amount equal to the Substitution Adjustment Amount, if any, and the Trustee,
upon receipt by it or the Custodian of the related Eligible Substitute Mortgage
Loan or Loans and certification by the Servicer of such deposit, shall release
to the Seller the related Mortgage File or Files and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse,
representation or warranty, as the Seller shall deliver to it and as shall be
necessary to vest therein any Defective Mortgage Loan released pursuant hereto.

     In addition, the Seller shall obtain at its own expense and deliver to the
Trustee an Opinion of Counsel to the effect that such substitution will not
cause (a) any federal tax to be imposed on the Trust Fund, including without
limitation, any federal tax imposed on "prohibited transactions" under Section
860F(a)(l) of the Code or on "contributions after the startup date" under
Section 860G(d)(l) of the Code, or (b) any REMIC formed under this Agreement to
fail to qualify as a REMIC at any time that any Certificate is outstanding. If
such Opinion of Counsel cannot be delivered, then such substitution may only be
effected at such time as the required Opinion of Counsel can be given.

          (e) Upon discovery by the Seller, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code, the party discovering such fact shall within two
Business Days give written notice thereof to the other parties. In connection
therewith, the Seller shall repurchase or, subject to the limitations set forth
in Section 2.03(d), substitute one or more Eligible Substitute Mortgage Loans
for the affected Mortgage Loan within 90 days of the earlier of discovery or
receipt of such notice with respect to such affected Mortgage Loan. In addition,
upon discovery that a Mortgage Loan is defective in a manner that would cause it
to be a "defective obligation" within the meaning of Treasury regulations
relating to REMICs, the Seller shall cure the defect or make the required
purchase or substitution no later than 90 days after the discovery of the
defect. Any such repurchase or substitution shall be made in the same manner as
set forth in Section 2.03(a), if made by the Seller. The Trustee shall reconvey
to the Seller the Mortgage Loan to be released pursuant hereto in the same
manner, and on the same terms and conditions, as it would a Mortgage Loan
repurchased for breach of a representation or warranty.

     Notwithstanding anything to the contrary contained herein, the parties
hereto acknowledge that the functions of the Custodian with respect to the
custody, acceptance, inspection and release of the Mortgage Files pursuant to
Sections 2.01, 2.02 and 2.03 and preparation and delivery of the certifications
in the form of Exhibit F-1 and Exhibit F-2 shall be performed by the Custodian
pursuant to the terms and conditions of the Custodial Agreement. The fees and
expenses of the Custodian shall be paid by the Servicer.

     Section 2.04 Representations and Warranties of the Seller with Respect to
the Mortgage Loans.

such other date specifically provided herein:

          (a) The representations and warranties made by the Seller pursuant to
Section 3.01 of the Mortgage Loan Purchase Agreement are hereby being made to
the Trustee and are true and correct as of the Closing Date.

          (b) Any written agreement between the Mortgagor in respect of a
Mortgage Loan and the Servicer modifying such Mortgagor's obligation to make

Mortgage Loan") involved some assessment of the Mortgagor's ability to repay the
Modified Mortgage Loan.

Section 2.04 that are made to the best of the Seller's knowledge or as to which
the Seller has no knowledge, if it is discovered by the Depositor, the Seller,
the Servicer or the Trustee that the substance of such representation and
warranty is inaccurate and such inaccuracy materially and adversely affects the
value of the related Mortgage Loan or the interest therein of the
Certificateholders then, notwithstanding the Seller's lack of knowledge with
respect to the substance of such representation and warranty being inaccurate at
the time the representation or warranty was made, such inaccuracy shall be
deemed a breach of the applicable representation or warranty.

a breach of any of the representations and warranties contained in this Section
that materially and adversely affects the value of any Mortgage Loan or the
interest therein of the Certificateholders, the party discovering the breach
shall give prompt written notice to the others and in no event later than two
Business Days from the date of such discovery. Within ninety days of its
discovery or its receipt of notice of any such missing or materially defective
documentation or any such breach of a representation or warranty, the Seller
shall promptly deliver such missing document or cure such defect or breach in
all material respects, or in the event such defect or breach cannot be cured,
the Seller shall repurchase the affected Mortgage Loan or cause the removal of
such Mortgage Loan from the Trust Fund and substitute for it one or more
Eligible Substitute Mortgage Loans, in either case, in accordance with Section
2.03.

     It is understood and agreed that the representations and warranties set
forth in this Section 2.04 shall survive delivery of the Mortgage Files to the
Trustee and shall inure to the benefit of the Certificateholders notwithstanding
any restrictive or qualified endorsement or assignment. It is understood and
agreed that the obligations of the Seller set forth in Section 2.03(a) and (c)
to cure, substitute for or repurchase a Mortgage Loan pursuant to the Mortgage
Loan Purchase Agreement and to reimburse the Trust the Reimbursement Amount,
constitute the sole remedies available to the Certificateholders or to the
Trustee on their behalf respecting a breach of the representations and
warranties contained in this Section 2.04.

     Section 2.05 Representations, Warranties and Covenants of the Servicer.

     The Servicer hereby represents, warrants and covenants to the Trustee, for
the benefit of each of the Trustee and the Certificateholders and to the
Depositor that as of the Closing Date or as of such date specifically provided
herein:

standing under the laws of the jurisdiction of its formation and has all
licenses necessary to carry on its business as now being conducted, except for
such licenses, certificates and permits the absence of which, individually or in
the aggregate, would not have a material adverse effect on the ability of the
Servicer to conduct its business as it is presently conducted, and is licensed,
qualified and in good standing in the states where the Mortgaged Property is
located if the laws of such state require licensing or qualification in order to
conduct business of the type conducted by the Servicer or to ensure the
enforceability or validity of each Mortgage Loan; the Servicer has the power and
authority to execute and deliver this Agreement and to perform in accordance
herewith; the execution, delivery and performance of this Agreement (including
all instruments of transfer to be delivered pursuant to this Agreement) by the
Servicer and the consummation of the transactions contemplated hereby have been
duly and validly authorized; this Agreement evidences the valid, binding and

Servicer in accordance with its terms;

               (ii) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Servicer and will not
result in the breach of any term or provision of the certificate of formation or

               (v) The Servicer does not believe, nor does it have any reason or
cause to believe, that it cannot perform each and every covenant contained in
this Agreement;

               (vi) There is no action, suit, proceeding or investigation
pending or, to its knowledge, threatened against the Servicer that, either
individually or in the aggregate, may result in any material adverse change in
the business, operations, financial condition, properties or assets of the
Servicer, or in any material impairment of the right or ability of the Servicer
to carry on its business substantially as now conducted, or in any material
liability on the part of the Servicer, or that would draw into question the
validity or enforceability of this Agreement or of any action taken or to be
taken in connection with the obligations of the Servicer contemplated herein, or
that would be likely to impair materially the ability of the Servicer to perform
under the terms of this Agreement;

<PAGE>

               (vii) No consent, approval or order of any court or governmental
agency or body is required for the execution, delivery and performance by the
Servicer of or compliance by the Servicer with this Agreement or the
consummation of the transactions contemplated by this Agreement, except for such
consents, approvals, authorizations and orders, if any, that have been obtained;

               (viii) Neither this Agreement nor any information, certificate of
an officer, statement furnished in writing or report delivered to the Trustee by
the Servicer in connection with the transactions contemplated hereby contains or
will contain any untrue statement of a material fact or omits or will omit to
state a material fact necessary in order to make the statements contained
therein, in light of the circumstances under which they were made, not
misleading; and

               (ix) The Servicer has fully furnished, and shall continue to
fully furnish for so long as it is servicing the Mortgage Loans hereunder, in
accordance with the Fair Credit Reporting Act and its implementing regulations,
accurate and complete information on the Mortgagor credit files to Equifax,
Experian and Trans Union Credit Information Company on a monthly basis.

     It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee and shall inure to the benefit of the Trustee, the
Depositor and the Certificateholders. Upon discovery by any of the Depositor,
the Servicer, the Seller or the Trustee of a breach of any of the foregoing
representations, warranties and covenants which materially and adversely affects
the value of any Mortgage Loan or the interests therein of the
Certificateholders, the party discovering such breach shall give prompt written
notice (but in no event later than two Business Days following such discovery)
to the other parties hereto.

     Section 2.06 Representations and Warranties of the Depositor.

     The Depositor represents and warrants to the Trust and the Trustee on
behalf of the Certificateholders as follows:

               (i) This agreement constitutes a legal, valid and binding
obligation of the Depositor, enforceable against the Depositor in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect affecting the enforcement of creditors' rights in general
and except as such enforceability may be limited by general principles of equity
(whether considered in a proceeding at law or in equity);

               (ii) Immediately prior to the sale and assignment by the
Depositor to the Trustee on behalf of the Trust of each Mortgage Loan, the
Depositor had good and marketable title to each Mortgage Loan (insofar as such
title was conveyed to it by the Seller) subject to no prior lien, claim,
participation interest, mortgage, security interest, pledge, charge or other
encumbrance or other interest of any nature;

               (iii) As of the Closing Date, the Depositor has transferred all
right, title interest in the Mortgage Loans to the Trustee on behalf of the
Trust;

               (iv) The Depositor has not transferred the Mortgage Loans to the
Trustee on behalf of the Trust with any intent to hinder, delay or defraud any
of its creditors;

                                       71

<PAGE>

               (v) The Depositor has been duly incorporated and is validly

incorporation or by-laws or in default in the performance or observance of any
material obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other instrument to which
the Depositor is a party or by which it or its properties may be bound, which
default might result in any material adverse changes in the financial condition,
earnings, affairs or business of the Depositor or which might materially and
adversely affect the properties or assets, taken as a whole, of the Depositor;

               (vii) The execution, delivery and performance of this Agreement
by the Depositor, and the consummation of the transactions contemplated thereby,
do not and will not result in a material breach or violation of any of the terms
or provisions of, or, to the knowledge of the Depositor, constitute a default
under, any indenture, mortgage, deed of trust, loan agreement or other agreement
or instrument to which the Depositor is a party or by which the Depositor is
bound or to which any of the property or assets of the Depositor is subject, nor
will such actions result in any violation of the provisions of the certificate
of incorporation or by-laws of the Depositor or, to the best of the Depositor's
knowledge without independent investigation, any statute or any order, rule or
regulation of any court or governmental agency or body having jurisdiction over
the Depositor or any of its properties or assets (except for such conflicts,
breaches, violations and defaults as would not have a material adverse effect on
the ability of the Depositor to perform its obligations under this Agreement);

               (viii) To the best of the Depositor's knowledge without any
independent investigation, no consent, approval, authorization, order,
registration or qualification of or with any court or governmental agency or
body of the United States or any other jurisdiction is required for the issuance
of the Certificates, or the consummation by the Depositor of the other
transactions contemplated by this Agreement, except such consents, approvals,
authorizations, registrations or qualifications as (a) may be required under
State securities or Blue Sky laws, (b) have been previously obtained or (c) the
failure of which to obtain would not have a material adverse effect on the
performance by the Depositor of its obligations under, or the validity or
enforceability of, this Agreement; and

               (ix) There are no actions, proceedings or investigations pending
before or, to the Depositor's knowledge, threatened by any court, administrative
agency or other tribunal to which the Depositor is a party or of which any of
its properties is the subject: (a) which if determined adversely to the
Depositor would have a material adverse effect on the business, results of
operations or financial condition of the Depositor; (b) asserting the invalidity
of this Agreement or the Certificates; (c) seeking to prevent the issuance of
the Certificates or the consummation by the Depositor of any of the transactions
contemplated by this Agreement, as the case may be; (d) which might materially
and adversely affect the performance by the Depositor of its obligations under,
or the validity or enforceability of, this Agreement.

specifically provided herein:

               (i) The Seller is duly organized, validly existing and in good
standing as a limited liability company under the laws of the State of Delaware
and has the power and authority to own its assets and to transact the business
in which it is currently engaged. The Seller is duly qualified to do business
and is in good standing in each jurisdiction in which the character of the

contemplated hereunder and has taken all necessary action to authorize the
execution, delivery and performance of this Agreement. When executed and

obligations enforceable in accordance with its terms, except as enforcement of
such terms may be limited by (1) bankruptcy, insolvency, reorganization,
receivership, moratorium or similar laws affecting the enforcement of creditors'
rights generally and by the availability of equitable remedies, (2) general
equity principles (regardless of whether such enforcement is considered in a
proceeding in equity or at law) or (3) public policy considerations underlying
the securities laws, to the extent that such policy considerations limit the
enforceability of the provisions of this Agreement which purport to provide
indemnification from securities laws liabilities.

               (iii) The Seller holds all necessary licenses, certificates and
permits from all governmental authorities necessary for conducting its business
as it is presently conducted, except for such licenses, certificates and permits
the absence of which, individually or in the aggregate, would not have a
material adverse effect on the ability of the Seller to conduct its business as
it is presently conducted. It is not required to obtain the consent of any other
party or any consent, license, approval or authorization from, or registration
or declaration with, any governmental authority, bureau or agency in

of this Agreement, except for such consents, licenses, approvals or
authorizations, or registrations or declarations as shall have been obtained or
filed, as the case may be, prior to the Closing Date.

               (iv) The execution, delivery and performance of this Agreement by
the Seller will not conflict with or result in a breach of, or constitute a
default under, any provision of any existing law or regulation or any order or
decree of any court applicable to the Seller or any of its properties or any
provision of its Limited Liability Company Agreement, or constitute a material
breach of, or result in the creation or imposition of any lien, charge or
encumbrance upon any of its properties pursuant to any mortgage, indenture,
contract or other agreement to which it is a party or by which it may be bound.

               (v) No certificate of an officer, written statement or report
delivered pursuant to the terms hereof by the Seller contains any untrue
statement of a material fact or omits to state any material fact necessary to
make the certificate, statement or report not misleading.

               (vi) The transactions contemplated by this Agreement are in the
ordinary course of the Seller's business.

               (vii) The Seller is not insolvent, nor will the Seller be made
insolvent by the transfer of the Mortgage Loans to the Depositor, nor is the
Seller aware of any pending insolvency.

               (viii) The Seller is not in violation of, and the execution and
delivery of this Agreement by it and its performance and compliance with the
terms of this Agreement will not constitute a violation with respect to any
order or decree of any court, or any order or regulation of any federal, state,
municipal or governmental agency having jurisdiction, which violation would
materially and adversely affect the Seller's condition (financial or otherwise)
or operations or any of the Seller's properties, or materially and adversely
affect the performance of any of its duties hereunder.

               (ix) There are no actions or proceedings against, or
investigations of, the Seller pending or, to its knowledge, threatened, before
any court, administrative agency or other tribunal (i) that, if determined
adversely, would prohibit the Seller from entering into this Agreement, (ii)
seeking to prevent the consummation of any of the transactions contemplated by
this Agreement or (iii) that, if determined adversely, would prohibit or
materially and adversely affect the Seller's performance of any of its
respective obligations under, or the validity or enforceability of, this
Agreement.

               (x) The Seller did not transfer the Mortgage Loans to the
Depositor with any intent to hinder, delay or defraud any of its creditors.

               (xi) The Seller acquired title to the Mortgage Loans in good
faith, without notice of any adverse claims.

               (xii) The transfer, assignment and conveyance of the Mortgage
Notes and the Mortgages by the Seller to the Depositor are not subject to the
bulk transfer laws or any similar statutory provisions in effect in any
applicable jurisdiction.

     Section 2.09 Covenants of the Seller.

     The Seller hereby covenants that except for the transfer hereunder, the
Seller will not sell, pledge, assign or transfer to any other Person, or grant,
create, incur, assume or suffer to exist any lien on any Mortgage Loan, or any
interest therein; the Seller will notify the Trustee, as assignee of the
Depositor, of

                                       74

<PAGE>

the existence of any lien on any Mortgage Loan immediately upon discovery
thereof, and the Seller will defend the right, title and interest of the Trust,
as assignee of the Depositor, in, to and under the Mortgage Loans, against all
claims of third parties claiming through or under the Seller; provided, however,
that nothing in this Section 2.09 shall prevent or be deemed to prohibit the
Seller from suffering to exist upon any of the Mortgage Loans any liens for
municipal or other local taxes and other governmental charges if such taxes or
governmental charges shall not at the time be due and payable or if the Seller
shall currently be contesting the validity thereof in good faith by appropriate
proceedings and shall have set aside on its books adequate reserves with respect
thereto.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

     Section 3.01 Servicer to Act as Servicer.

     The Servicer, as independent contract servicer, shall service and
administer the Mortgage Loans in accordance with this Agreement and the normal
and usual standards of practice of prudent mortgage servicers, and shall have
full power and authority, acting alone, to do or cause to be done any and all
things in connection with such servicing and administration which the Servicer
may deem necessary or desirable and consistent with the terms of this Agreement
and consistent with the standard of care which the Servicer uses and/or would
use in servicing mortgage loans for its own account (the "Servicing Standards").

     Consistent with the terms of this Agreement, the Servicer may waive, modify
or vary any term of any Mortgage Loan or consent to the postponement of strict
compliance with any such term or in any manner grant indulgence to any Mortgagor
if in the Servicer's reasonable and prudent determination such waiver,
modification, postponement or indulgence is not materially adverse to the
Certificateholders; provided, however, that the Servicer shall not make future
advances and (unless the Mortgagor is in default with respect to the Mortgage
Loan or such default is, in the judgment of the Servicer, reasonably
foreseeable) the Servicer shall not permit any modification with respect to any
Mortgage Loan that would (i) change the Mortgage Interest Rate, defer or forgive
the payment thereof of any principal or interest payments, reduce the
outstanding principal amount (except for actual payments of principal) or extend
the final maturity date with respect to such Mortgage Loan, (ii) affect
adversely the status of any REMIC constituting part of the Trust Fund as a REMIC
or (iii) cause any REMIC to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions. Notwithstanding the foregoing,
the Servicer shall not permit any modification with respect to any Mortgage Loan
that would both (x) effect an exchange or reissuance of such Mortgage Loan under
Section 1.860G-2(b) of the Treasury Regulations and (y) cause any REMIC
constituting part of the Trust Fund to fail to qualify as a REMIC under the Code
or the imposition of any tax on "prohibited transactions" or "contributions"
after the Startup Day under the REMIC Provisions. Without limiting the
generality of the foregoing, the Servicer shall continue, and is hereby
authorized and empowered to execute and deliver on behalf of itself, and the
Trustee, all instruments of satisfaction or cancellation, or of partial or full
release, discharge and all other comparable instruments, with respect to the
Mortgage Loans and with respect to the Mortgaged Property. The Servicer shall
make all required Servicing Advances and shall service and administer the
Mortgage Loans in accordance with Applicable Regulations, and shall provide to
the Mortgagors any reports required to be provided to them thereby. If
reasonably required by the Servicer, the Trustee shall furnish the Servicer a
power of attorney (substantially in the form annexed hereto as Exhibit O) and
other documents necessary or appropriate to enable the Servicer to carry out its
servicing and administrative duties under this Agreement. The Trustee shall not
be liable for the actions of the

                                       75

<PAGE>

Servicer or any Subservicers under such powers of attorney and shall be
indemnified by the Servicer for any costs, liabilities or expenses incurred by
the Trustee in connection with the Servicer's misuse of such powers of attorney.

     Notwithstanding anything contained herein to the contrary, the Servicer
shall not, without the Trustee's written consent: (i) initiate any action, suit
or proceeding directly relating to the servicing of a Mortgage Loan solely under
the Trustee's name without indicating the Servicer's representative capacity
(provided that the Servicer shall not be required to sign the power of attorney
in order to perform the functions enumerated therein), (ii) initiate any other
action, suit or proceeding not directly relating to the servicing of a Mortgage
Loan (including but not limited to actions, suits or proceedings against
Certificateholders, or against the Depositor or the Seller for breaches of
representations and warranties) solely under the Trustee's name, (iii) engage
counsel to represent the Trustee in any action, suit or proceeding not directly
related to the servicing of any Mortgage Loan (including but not limited to
actions, suits or proceedings against Certificateholders, or against the
Depositor or the Seller for breaches of representations and warranties, or (iv)
prepare, execute or deliver any government filings, forms, permits,
registrations or other documents or take any action with the intent to cause,
and that actually causes, the Trustee to be registered to do business in any
state.

     In servicing and administering the Mortgage Loans, the Servicer shall
employ procedures including collection procedures and exercise the same care
that it customarily employs and exercises in servicing and administering
mortgage loans for its own account giving due consideration to accepted mortgage
servicing practices of prudent lending institutions and the Certificateholders'
reliance on the Servicer.

     The Servicer shall give prompt notice to the Trustee of any action, of
which the Servicer has actual knowledge, which action purports to (i) assert a
claim against the Trust Fund or (ii) assert jurisdiction over the Trust Fund.

     Notwithstanding anything in this Agreement to the contrary, in the event of
a Principal Prepayment in full, the Servicer may not waive any prepayment
penalty or portion thereof required by the terms of the related Mortgage Note
unless (i) the related Mortgage Loan is in default or foreseeable default and
such waiver (a) is standard and customary in servicing mortgage loans similar to
the Mortgage Loans and (b) would, in the reasonable judgment of the Servicer,
maximize recovery of total proceeds taking into account the value of such
prepayment penalty and the related Mortgage Loan, (ii) (A) the enforceability
thereof is limited (1) by bankruptcy, insolvency, moratorium, receivership, or
other similar law relating to creditors' rights generally or (2) due to
acceleration in connection with a foreclosure or other involuntary payment, or
(B) the enforceability is otherwise limited or prohibited by applicable law,
(iii) if the Servicer has not been provided with information sufficient to
enable it to collect the prepayment penalty or (iv) if the collection of such
prepayment penalty would be considered "predatory" pursuant to written guidance
published or issued by an applicable federal, state, or local regulatory
authority acting in its official capacity and having jurisdiction over such
matters. In the event of a Principal Prepayment in full with respect to any
Mortgage Loan, the Servicer shall deliver to the Trustee an Officer's
Certificate, substantially in the form of Exhibit Q, no later than the third
Business Day following the immediately succeeding Determination Date. For the
avoidance of doubt, the Servicer may waive a prepayment penalty in connection
with a short sale or short payoff on a defaulted Mortgage Loan. If the Servicer
has waived all or a portion of a prepayment penalty relating to a Principal
Prepayment, other than as provided above, the Servicer shall deliver to the
Trustee as soon as possible after the date of payoff, but in no event later than
five business days from such date, for deposit into the Distribution Account the
amount of such prepayment penalty (or such portion thereof as had been waived)
for distribution in accordance with the terms of this Agreement.

                                       76

<PAGE>

     During the period when reports are required to be filed for the Trust under
the Exchange Act, the Servicer shall not permit a Subservicer to perform any
servicing responsibilities hereunder with respect to the Mortgage Loans unless
that Subservicer first agrees in writing with the Servicer to deliver an
Assessment of Compliance and an Accountant's Attestation in such manner and at
such times that permits the Servicer to comply with Section 3.20 of this
Agreement.

     With respect to Mortgage Loans affected by a hurricane or other natural
disaster, if the Mortgaged Property is located in public and individual
assistance counties, as designated by Federal Emergency Management Agency (as
set forth on its website www.fema.gov), Servicer may, at its sole option, cease
collection activities, charging late fees and credit reporting activity for all
Mortgagors in such counties for a period of time and, if reasonably prudent, may
extend such period as long as it deems necessary. In addition, the Servicer may
suspend all foreclosure and bankruptcy activity relating to such Mortgage Loans
for a period of time and, if reasonably prudent, may extend such period as long
as it deems necessary.

     Section 3.02 Collection of Mortgage Loan Payments.

     Continuously from the date hereof until the principal and interest on all
Mortgage Loans are paid in full, the Servicer will diligently collect all
payments due under each Mortgage Loan when the same shall become due and payable
and shall, to the extent such procedures shall be consistent with this Agreement
and the terms and provisions of any related Primary Insurance Policy and
Applicable Regulations, follow such collection procedures as it follows with
respect to mortgage loans comparable to the Mortgage Loans and held for its own
account. Further, the Servicer will take special care in ascertaining and
estimating taxes, fire and hazard insurance premiums, mortgage insurance
premiums, and all other charges that, as provided in the Mortgage, will become
due and payable to that end that the installments payable by the Mortgagors will
be sufficient to pay such charges as and when they become due and payable.

     Section 3.03 Realization Upon Defaulted Mortgage Loans.

     In the event that any payment due under any Mortgage Loan is not paid when
the same becomes due and payable, or in the event the Mortgagor fails to perform
any other covenant or obligation under the Mortgage Loan and such failure
continues beyond any applicable grace period, the Servicer shall take such
action as it shall deem to be in the best interest of the Certificateholders,
including either foreclosing on any such Mortgage Loan or working out an
agreement with the Mortgagor, which may involve waiving or modifying certain
terms of the Mortgage Loan. With respect to any defaulted Mortgage Loan, the
Servicer shall have the right to review the status of the related forbearance
plan and, subject to the second paragraph of Section 3.01, may modify such
forbearance plan; including, extending the Mortgage Loan repayment date for a
period of one year, which period will not go beyond the latest Final Maturity
Date.

     In connection with a foreclosure or other conversion, the Servicer shall
exercise such rights and powers vested in it hereunder and use the same degree
of care and skill in its exercise as prudent mortgage servicers would exercise
or use under the circumstances in the conduct of their own affairs and
consistent with Applicable Regulations and the servicing standards set forth in
the Fannie Mae Guide, including, without limitation, advancing funds for the
payment of taxes and insurance premiums with respect to first lien Mortgage
Loans.

     Notwithstanding the foregoing provisions of this Section 3.03, with respect
to any Mortgage Loan as to which the Servicer has received actual notice of, or
has actual knowledge of, the presence of any

                                       77

<PAGE>

toxic or hazardous substance on the related Mortgaged Property, the Servicer
shall not either (i) obtain title to such Mortgaged Property as a result of or
in lieu of foreclosure or otherwise, or (ii) otherwise acquire possession of, or
take any other action with respect to, such Mortgaged Property if, as a result
of any such action, the Trust Fund would be considered to hold title to, to be a
mortgagee-in-possession of, or to be an owner or operator of such Mortgaged
Property within the meaning of the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended from time to time, or any
comparable law, unless the Servicer has also previously determined, based on its
reasonable judgment and a prudent report prepared by a Person who regularly
conducts environmental audits using customary industry standards, that:

     A. such Mortgaged Property is in compliance with applicable environmental
laws or, if not, that it would be in the best economic interest of the
Certificateholders to take such actions as are necessary to bring the Mortgaged
Property into compliance therewith; and

     B. there are no circumstances present at such Mortgaged Property relating
to the use, management or disposal of any hazardous substances, hazardous
materials, hazardous wastes, or petroleum-based materials for which
investigation, testing, monitoring, containment, clean-up or remediation could
be required under any federal, state or local law or regulation, or that if any
such materials are present for which such action could be required, that it
would be in the best economic interest of the Certificateholders to take such
actions with respect to the affected Mortgaged Property.

     The cost of the environmental audit report contemplated by this Section
3.03 shall be advanced by the Servicer, subject to the Servicer's right to be
reimbursed therefor from the Collection Account as provided in Section 3.05(ii).

     If the Servicer determines, as described above, that it is in the best
economic interest of the Certificateholders to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes, or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Certificateholders. The cost of any such compliance,
containment, cleanup or remediation shall be advanced by the Servicer, subject
to the Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.05(ii).

     Section 3.04 Collection Account and Distribution Account.

          (a) The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan separate and apart from any of its own
funds and general assets and shall establish and maintain one or more Collection
Accounts. Each Collection Account shall be an Eligible Account.

     The Servicer shall deposit in the Collection Account on a daily basis
within two Business Days of determining the proper application after receipt of
such funds, and retain therein, the following payments and collections received
or made by it after the Cut-off Date with respect to the Mortgage Loans:

               (i) all payments on account of principal, including Principal
Prepayments, on the Mortgage Loans;

               (ii) all payments on account of interest on the Mortgage Loans
adjusted to the Mortgage Interest Rate less the Servicing Fee Rate;

                                       78

<PAGE>

               (iii) all proceeds from a Cash Liquidation;

               (iv) all Insurance Proceeds including amounts required to be
deposited pursuant to Section 3.10, other than proceeds to be held in the Escrow
Account and applied to the restoration or repair of the Mortgaged Property or
released to the Mortgagor in accordance with the Servicer's normal servicing
procedures, the loan documents or applicable law;

               (v) all Condemnation Proceeds affecting any Mortgaged Property
which are not released to the Mortgagor in accordance with the Servicer's normal
servicing procedures, the loan documents or applicable law; and

               (vi) any amounts required to be deposited by the Servicer in
connection with any REO Property pursuant to Section 3.13.

     Any interest paid on funds deposited in the Collection Account, subject to
Section 3.25, shall accrue to the benefit of the Servicer and the Servicer shall
be entitled to retain and withdraw such interest from the Collection Account
pursuant to Section 3.05(v). The foregoing requirements for deposit from the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of late
payment charges, prepayment charges that are not prepayment penalties, and
assumption fees need not be deposited by the Servicer in the Collection Account.

          (b) On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Certificateholders. On behalf of
the Trust Fund, the Servicer shall deliver to the Trustee in immediately
available funds for deposit in the Distribution Account by the 3:00 PM New York
time on the Servicer Remittance Date, that portion of the Available Funds
(calculated without regard to the references in the definition thereof to
amounts that may be deposited to the Distribution Account from a different
source as provided herein) then on deposit in the Collection Account; provided,
further, in connection with any failure by the Servicer to make any remittance
required to be made by the Servicer to the Distribution Account on the day and
by the time such remittance is required to be made under the terms of this
Agreement (without giving effect to any grace or sure period), the Servicer
shall pay to the Trustee for the account of the Trustee interest at the Prime
Rate or such other rate mutually agreed to between the Servicer and the Trustee
or any amount not timely remitted from and including the day such remittance was
required to be made to, but not including, the day on which such remittance was
actually made. Amounts in the Distribution Account shall be deemed to be held on
behalf of the related REMICs in accordance with the REMIC distributions set
forth in Section 9.01. Funds on deposit in the Distribution Account may be
invested in Permitted Investments.

          (c) Funds in the Collection Account may be invested in Permitted
Investments in accordance with the provisions set forth in Section 3.25. The
Servicer shall give notice to the Trustee certifying the location of the
Collection Account maintained by it when established and prior to any change
thereof. The Trustee shall give notice to the Servicer and the Depositor of the
location of the Distribution Account when established and prior to any change
thereof.

          (d) In the event the Servicer shall deliver to the Trustee for deposit
in the Distribution Account any amount not required to be deposited therein, it
may at any time in writing request that the Trustee withdraw such amount from
the Distribution Account and remit to the Servicer any such amount, any
provision herein to the contrary notwithstanding. In addition, the Servicer
shall deliver to the Trustee from time to time for deposit, and the Trustee
shall so deposit, in the Distribution Account in respect of the SWAP REMIC
(provided, however, that notwithstanding the foregoing, any amounts
distributable to the Class P Certificates shall not, for federal income tax
purposes, be treated as part of any REMIC):

               (i) any Advances, as required pursuant to Section 4.07;

                                       79

<PAGE>

               (ii) any Stayed Funds, as soon as permitted by the federal
bankruptcy court having jurisdiction in such matters;

               (iii) any prepayment penalties or amounts in connection with the
waiver of such prepayment penalties, in each case required to be deposited
pursuant to Section 3.01;

               (iv) any amounts required to be deposited in the Distribution
Account pursuant to Sections 2.03, 3.04, 3.15, 3.16, 3.23 or 4.07; and

               (v) any amounts required to be deposited by the Servicer pursuant
to Section 3.11 in connection with the deductible clause in any blanket hazard
insurance policy, such deposit being made from the Servicer's own funds, without
reimbursement therefor.

          (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source,
the Trustee shall notify the Servicer of such receipt and deposit such funds in
the Distribution Account, subject to withdrawal thereof as permitted hereunder.

     Section 3.05 Permitted Withdrawals From the Collection Account.

     The Servicer may, from time to time, withdraw from the Collection Account
for the following purposes:

               (i) to remit to the Trustee for deposit in the Distribution
Account (a) the amounts required to be so remitted pursuant to Section 3.04(b),
(b) the amounts permitted to be so remitted pursuant to the first sentence of
Section 3.04(d) or clause (ii) of the first sentence of the second paragraph of
Section 4.07(b), (c) any amounts required to be so remitted pursuant to Section
6.03 and (d) any amounts required to be so remitted pursuant to Section 8.05;

               (ii) to reimburse itself for (a) Advances and Servicing Advances
to the extent of amounts received on the related Mortgage Loan which represent
payments of (x) principal and/or interest respecting which any such Advance was
made or (y) Condemnation Proceeds, Insurance Proceeds or Liquidation Proceeds
respecting which any such Servicing Advance was made; or (b) any unreimbursed
Advances or Servicing Advances to the extent of funds held in the Collection
Account for future distributions that were not included in Available Funds for
the preceding Distribution Date (provided, however, any funds so applied will be
replaced by the Servicer by deposit in the Collection Account no later than one
Business Day prior to the Distribution Date on which such funds are required to
be distributed) and to reimburse itself for Advances and Servicing Advances made
in connection with the modification of a Mortgage Loan;

               (iii) to reimburse itself for unreimbursed Servicing Advances,
any unpaid Servicing Fees and for unreimbursed Advances to the extent that such
amounts are deemed to be Nonrecoverable Advances and to reimburse itself for
such amounts to the extent that such amounts are nonrecoverable from the
disposition of the related REO Property or have been written-off pursuant to
Section 3.13 hereof;

               (iv) to reimburse itself for any amounts paid pursuant to Section
3.03 (and not otherwise previously reimbursed);

                                       80

<PAGE>

               (v) to pay to itself as servicing compensation (a) any interest
earned on funds in the Collection Account (all such interest to be withdrawn
monthly not later than each Servicer Remittance Date) and (b) the Servicing Fee
from that portion of any payment or recovery as to interest to a particular
Mortgage Loan to the extent not retained pursuant to Section 3.04(d);

               (vi) to pay or reimburse itself for any amounts payable or paid
pursuant to Section 6.03 (and not otherwise previously reimbursed) and to
reimburse itself as set forth in Section 9.01(c); and

               (vii) to clear and terminate the Collection Account upon the
termination of this Agreement.

     The foregoing requirements for withdrawal from the Collection Account shall
be exclusive. In the event the Servicer shall deposit in the Collection Account
any amount not required to be deposited therein, it may at any time withdraw
such amount from the Collection Account, any provision herein to the contrary
notwithstanding.

     Section 3.06 Establishment of Escrow Account; Deposits in Escrow Account.

     The Servicer shall segregate and hold all funds collected and received
pursuant to each Mortgage Loan which constitute Escrow Payments separate and
apart from any of its own funds and general assets and shall establish and
maintain one or more Escrow Accounts, in the form of time deposit or demand
accounts. A copy of such letter agreement shall be furnished to the Trustee upon
request. The Escrow Account shall be an Eligible Account.

     The Servicer shall deposit in the Escrow Account on a daily basis within
two Business Days of receipt, and retain therein, (i) all Escrow Payments
collected on account of the Mortgage Loans, for the purpose of effecting timely
payment of any such items as required under the terms of this Agreement, and
(ii) all Insurance Proceeds which are to be applied to the restoration or repair
of any Mortgaged Property. The Servicer shall make withdrawals therefrom only to
effect such payments as are required under this Agreement, and for such other
purposes as shall be set forth in, or in accordance with, Section 3.07. The
Servicer shall be entitled to retain any interest paid on funds deposited in the
Escrow Account by the depository institution other than interest on escrowed
funds required by law to be paid to the Mortgagor and, to the extent required by
the related Mortgage Loan or Applicable Regulations, the Servicer shall pay
interest on escrowed funds to the Mortgagor notwithstanding that the Escrow
Account is non-interest bearing or that interest paid thereon is insufficient
for such purposes.

     Section 3.07 Permitted Withdrawals From Escrow Account.

     Withdrawals from the Escrow Account may be made by the Servicer (i) to
effect timely payments of taxes, fire, flood and hazard insurance premiums,
Primary Insurance Policy premiums, if applicable, and comparable items, (ii) to
reimburse the Servicer for any Servicing Advance made by the Servicer with
respect to a related Mortgage Loan but only from amounts received on the related
Mortgage Loan which represent late payments or Late Collections of Escrow
Payments thereunder, (iii) to refund to the Mortgagor any funds as may be
determined to be overages, (iv) for transfer to the Collection Account in
accordance with the terms of this Agreement, (v) for application to restoration
or repair of the Mortgaged Property, (vi) to pay to the Servicer, or to the
Mortgagor to the extent required by the related Mortgage Loan or Applicable
Regulations, any interest paid on the funds deposited in the Escrow Account,
(vii) to clear and terminate the Escrow Account on the termination of this
Agreement, or (viii) to transfer to the Collection Account any insurance
proceeds. As part of its servicing duties, the Servicer shall pay to the

                                       81

<PAGE>

Mortgagor interest on funds in the Escrow Account, to the extent required by the
related Mortgage Loan or Applicable Regulations, and to the extent that interest
earned on funds in the Escrow Account is insufficient, shall pay such interest
from its own funds, without any reimbursement therefor.

     In the event the Servicer shall deposit in the Escrow Account any amount
not required to be deposited therein, it may at any time withdraw such amount
from the Escrow Account, any provision herein to the contrary notwithstanding.

     Section 3.08 Payment of Taxes, Insurance and Other Charges; Collections
Thereunder.

     With respect to each first lien Mortgage Loan, the Servicer shall maintain
accurate records reflecting the status of taxes and other charges which are or
may become a lien upon the Mortgaged Property and the status of Primary
Insurance Policy premiums and fire, flood and hazard insurance coverage and
shall obtain, from time to time, all bills for the payment of such charges
(including renewal premiums) and shall effect payment thereof prior to the
applicable penalty or termination date and at a time appropriate for securing
maximum discounts allowable, employing for such purpose deposits of the
Mortgagor in the Escrow Account which shall have been estimated and accumulated
by the Servicer in amounts sufficient for such purposes, as allowed under the
terms of the Mortgage or Applicable Regulations. To the extent that a Mortgage
does not provide for Escrow Payments, the Servicer shall (i) determine whether
any such payments are made by the Mortgagor in a manner and at a time that is
necessary to avoid the loss of the Mortgaged Property due to a tax sale or the
foreclosure as a result of a tax lien and (ii) ensure that all insurance
required to be maintained on the Mortgaged Property pursuant to this Agreement
is maintained. If any such payment has not been made and the Servicer receives
notice of a tax lien with respect to the Mortgage Loan being imposed, the
Servicer will, to the extent required to avoid loss of the Mortgaged Property,
advance or cause to be advanced funds necessary to discharge such lien on the
Mortgaged Property. The Servicer assumes full responsibility for the payment of
all such bills and shall effect payments of all such bills irrespective of the
Mortgagor's faithful performance in the payment of same or the making of the
Escrow Payments and shall make Servicing Advances from its own funds to effect
such payments.

     The Servicer, on behalf of the Trustee, as mortgagee, will maintain in full
force and effect (to the extent a Mortgage Loan has a Primary Insurance Policy)
a Primary Insurance Policy issued by a Qualified Insurer with respect to each
Mortgage Loan for which such coverage is required. Such coverage will be
maintained until the Combined Loan-to-Value Ratio of the related Mortgage Loan
is reduced to 80% or less. The Servicer will not cancel or refuse to renew any
Primary Insurance Policy in effect on the Closing Date that is required to be
kept in force under this Agreement unless a replacement Primary Insurance Policy
for such cancelled or non-renewed policy is obtained from and maintained with a
Qualified Insurer. The Servicer shall not take any action which would result in
non-coverage under any applicable Primary Insurance Policy of any loss which,
but for the actions of the Servicer, would have been covered thereunder. In
connection with any assumption or substitution agreement entered into or to be
entered into pursuant to Section 3.14, the Servicer shall promptly notify the
insurer under the related Primary Insurance Policy, if any, of such assumption
or substitution of liability in accordance with the terms of such policy and
shall take all actions which may be required by such insurer as a condition to
the continuation of coverage under the Primary Insurance Policy. If such Primary
Insurance Policy is terminated as a result of such assumption or substitution of
liability, the Servicer shall obtain a replacement Primary Insurance Policy as
provided above.

     In connection with its activities as servicer, the Servicer agrees to
prepare and present, on behalf of itself and the Trustee, claims to the insurer
under any Primary Insurance Policy in a timely fashion in accordance with the
terms of such policies and, in this regard, to take such action as shall be
necessary to

                                       82

<PAGE>

permit recovery under any Primary Insurance Policy respecting a defaulted
Mortgage Loan. Pursuant to Section 3.04, any amounts collected by the Servicer
under any Primary Insurance Policy shall be deposited in the Collection Account,
subject to withdrawal pursuant to Section 3.05.

     Section 3.09 Transfer of Accounts.

     The Servicer may transfer the Collection Account or the Escrow Account to a
different depository institution from time to time, provided such depository
institutions shall maintain Eligible Accounts. Upon such transfer, the Servicer
shall deliver to the Trustee and the Depositor, a certification or letter
agreement, as the case may be, as required pursuant to Sections 3.04 and 3.06.

     Section 3.10 Maintenance of Hazard Insurance.

     The Servicer shall cause to be maintained for each first lien Mortgage Loan
fire and hazard insurance with extended coverage as is customary in the area
where the Mortgaged Property is located in an amount which is at least equal to
the lesser of (i) the amount necessary to fully compensate for any damage or
loss to the improvements which are a part of such property on a replacement cost
basis and (ii) the Principal Balance of the Mortgage Loan, in each case in an
amount not less than such amount as is necessary to prevent the Mortgagor and/or
the Mortgagee from becoming a co-insurer. If the Mortgaged Property is in an
area identified in the Federal Register by the Flood Emergency Management Agency
as having special flood hazards and flood insurance has been made available, the
Servicer will cause to be maintained a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
with a generally acceptable insurance carrier, in an amount representing
coverage not less than the least of (i) the Principal Balance of the Mortgage
Loan, (ii) the maximum insurable value of the improvements securing such
Mortgage Loan or (iii) the maximum amount of insurance which is available under
the Flood Disaster Protection Act of 1973, as amended. The Servicer shall also
maintain on the REO Property for the benefit of the Certificateholders, (x) fire
and hazard insurance with extended coverage in an amount which is at least equal
to the replacement cost of the improvements which are a part of such property,
(y) public liability insurance and, (z) to the extent required and available
under the Flood Disaster Protection Act of 1973, as amended, flood insurance in
an amount as provided above. Any amounts collected by the Servicer under any
such policies other than amounts to be deposited in the Escrow Account and
applied to the restoration or repair of the Mortgaged Property or REO Property,
or released to the Mortgagor in accordance with the Servicer's normal servicing
procedures, shall be deposited in the Collection Account, subject to withdrawal
pursuant to Section 3.05. It is understood and agreed that no earthquake or
other additional insurance is required to be maintained by the Servicer or the
Mortgagor or maintained on property acquired in respect of the Mortgage Loan,
other than pursuant to such Applicable Regulations as shall at any time be in
force and as shall require such additional insurance. All such policies shall be
endorsed with standard mortgagee clauses with loss payable to the Servicer and
shall provide for at least thirty days prior written notice of any cancellation,
reduction in the amount of or material change in coverage to the Servicer. The
Servicer shall not interfere with the Mortgagor's freedom of choice in selecting
either his insurance carrier or agent, provided, however, that the Servicer
shall not accept any such insurance policies from insurance companies unless
such companies currently reflect a general policy rating of B:VI or better in
Best's Key Rating Guide and are licensed to do business in the state wherein the
property subject to the policy is located.

     Section 3.11 Maintenance of Mortgage Impairment Insurance Policy.

     In the event that the Servicer shall obtain and maintain a blanket policy
issued by an insurer that has a general policy rating of B:VI or better in
Best's Key Rating Guide insuring against hazard losses on

                                       83

<PAGE>

all of the Mortgage Loans, then, to the extent such policy provides coverage in
an amount equal to the amount required pursuant to Section 3.10 and otherwise
complies with all other requirements of Section 3.10, it shall conclusively be
deemed to have satisfied its obligations as set forth in Section 3.10, it being
understood and agreed that such policy may contain a deductible clause, in which
case the Servicer shall, in the event that there shall not have been maintained
on the related Mortgaged Property or REO Property a policy complying with
Section 3.10, and there shall have been a loss which would have been covered by
such policy, deliver to the Trustee for deposit in the Distribution Account the
amount not otherwise payable under the blanket policy because of such deductible
clause, which amount shall not be reimbursable to the Servicer from the Trust
Fund. In connection with its activities as servicer of the Mortgage Loans, the
Servicer agrees to prepare and present, on behalf of the Trustee, claims under
any such blanket policy in a timely fashion in accordance with the terms of such
policy. Upon request of the Trustee, the Servicer shall cause to be delivered to
the Trustee a certified true copy of such policy and a statement from the
insurer thereunder that such policy shall in no event be terminated or
materially modified without thirty days prior written notice to the Trustee.

     Section 3.12 Fidelity Bond, Errors and Omissions Insurance.

     The Servicer shall maintain, at its own expense, a blanket fidelity bond
(the "Fidelity Bond") and an errors and omissions insurance policy, with broad
coverage with financially responsible companies on all officers, employees or
other persons acting in any capacity with regard to the Mortgage Loans to handle
funds, money, documents and papers relating to the Mortgage Loans. The Fidelity
Bond and errors and omissions insurance shall be in the form of the Mortgage
Banker's Blanket Bond and shall protect and insure the Servicer against losses,
including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such persons. Such Fidelity Bond shall also protect and insure
the Servicer against losses in connection with the failure to maintain any
insurance policies required pursuant to this Agreement and the release or
satisfaction of a Mortgage Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section 3.12 requiring the
Fidelity Bond and errors and omissions insurance shall diminish or relieve the
Servicer from its duties and obligations as set forth in this Agreement. The
minimum coverage under any such bond and insurance policy shall be at least
equal to the corresponding amounts required by Fannie Mae in the Fannie Mae MBS
Selling and Servicing Guide or by Freddie Mac in the Freddie Mac Servicer's
Guide. Upon the request of any party hereto, each year the Servicer shall cause
to be delivered to such party proof of coverage of the Fidelity Bond and errors
and omissions insurance policy and a statement from the surety and the insurer
that the surety and the insurer shall endeavor to notify the Trustee within 30
days prior to such Fidelity Bond's errors and omissions insurance policy's
termination or material modification.

     Section 3.13 Title, Management and Disposition of REO Property and Certain
Delinquent Mortgage Loans.

          (a) In the event that title to a Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken (pursuant to a limited power of attorney to be provided by the
Trustee to the Servicer) in the name of the Trustee or a nominee thereof (which
nominee shall not be the Servicer), on behalf of the Certificateholders, or in
the event the Trustee or a nominee (which nominee shall not be the Servicer)
thereof is not authorized or permitted to hold title to real property in the
state where the REO Property is located, or would be adversely affected under
the "doing business" or tax laws of such state by so holding title, the deed or
certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Servicer from an
attorney duly licensed to practice law in the state where the REO Property is
located. Any Person or Persons holding such title other than the Trustee shall
acknowledge in writing that such title is being held as nominee for the benefit
of the Trustee. The Trustee's name shall be placed on the

                                       84

<PAGE>

title to such REO Property solely as the Trustee hereunder and not in its
individual capacity. The Servicer shall ensure that such title to such REO
Property references this Agreement and the Trustee's capacity hereunder.

          (b) In the event that the Trust Fund acquires any REO Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end of
the third calendar year beginning after the year of its acquisition by the Trust
Fund for purposes of Section 860G(a)(8) of the Code or if the Trust Fund has
received (at the expense of the Trust Fund) from the Internal Revenue Service an
extension of the period during which it may hold such REO Property without such
REO Property failing to be treated as "foreclosure property" (within the meaning
of Section 860G(a)(8) of the Code), before the end of such extension, unless the
Servicer obtains an Opinion of Counsel, addressed to the Servicer and the
Trustee, to the effect that the holding by the Trust Fund of such REO Property
subsequent to such period will not: (i) result in the imposition of any tax on
"prohibited transactions" as defined in Section 860F of the Code; or (ii) cause
any REMIC constituting part of the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates are outstanding, in which case the Trust Fund may
continue to hold such REO Property (subject to any conditions contained in such
Opinion of Counsel). The Servicer shall be entitled to be reimbursed from the
Collection Account for any costs incurred in obtaining such Opinion of Counsel,
as provided in Section 3.05.

     Subject to compliance with applicable laws and regulations as shall at any
time be in force, and notwithstanding any other provisions of this Agreement, no
REO Property acquired by the Trust Fund shall be rented (or allowed to continue
to be rented) or otherwise used by or on behalf of the Trust Fund in such a
manner or pursuant to any terms that would: (i) cause such REO Property to fail
to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code; or (ii) subject any REMIC constituting part of the Trust Fund to the
imposition of any federal income taxes on the income earned from such REO
Property, including any taxes imposed by reason of Sections 860F or 860G(c) of
the Code, unless the Servicer has agreed to indemnify and hold harmless the
Trust Fund with respect to the imposition of any such taxes.

     The Servicer shall manage, conserve, protect and operate each REO Property
for the Certificateholders and the Trust Fund solely for the purpose of its
prompt disposition and sale in a manner which does not cause such REO Property
to fail to qualify as "foreclosure property" within the meaning of Section
860G(a)(8) of the Code or result in the receipt by the related REMIC of any
"income from non-permitted assets" within the meaning of Section 860F(a)(2)(B)
of the Code, or any "net income from foreclosure property" which is subject to
taxation under the REMIC Provisions. The Servicer shall cause each REO Property
to be inspected promptly upon the acquisition of title thereto and shall cause
each REO Property to be inspected at least annually thereafter. The Servicer
shall make or cause to be made a written report of each such inspection. Such
reports shall be retained in the Mortgage Servicing File and copies thereof
shall be forwarded by the Servicer to the Trustee upon request. The Servicer
shall attempt to sell the same (and may temporarily rent the same) on such terms
and conditions as the Servicer deems to be in the best interest of the
Certificateholders and the Trust Fund.

     With respect to each REO Property, the Servicer shall account separately
for each REO Property with respect to all funds collected and received in
connection with the operation of such REO Property.

     The Servicer shall deposit or cause to be deposited, on a daily basis,
within two Business Days of determining the proper cash application after
receipt of such funds, in the Collection Account, all revenues received with
respect to each REO Property and shall withdraw therefrom funds necessary for
the proper operation, management and maintenance of the related REO Property,
including the cost of

                                       85

<PAGE>

maintaining any hazard insurance pursuant to Section 3.10 hereof and the fees of
any managing agent acting on behalf of the Servicer.

     The Servicer shall furnish to the Trustee, on each Servicer Remittance
Date, an operating statement for each REO Property covering the operation of
each REO Property for the previous month. Such operating statement shall be
accompanied by such other information as the Trustee shall reasonably request.

     The Servicer shall use its best efforts to dispose of the REO Property as
promptly as is practically consistent with protecting the Certificateholders'
interests.

     Each REO Disposition shall be carried out by the Servicer at such price and
upon such terms and conditions as the Servicer deems to be in the best interest
of the Certificateholders. If as of the date title to any REO Property was
acquired by the Servicer there were outstanding unreimbursed Servicing Advances
with respect to the REO Property or the related Mortgage Loan, the Servicer,
upon an REO Disposition of such REO Property, shall be entitled to reimbursement
for any related unreimbursed Servicing Advances from proceeds received in
connection with such REO Disposition. The proceeds from the REO Disposition, net
of any payment to the Servicer as provided above, shall be deposited in the
Collection Account for distribution on the succeeding Servicer Remittance Date
in accordance with Section 4.01.

     Any REO Disposition shall be for cash only (unless changes in the REMIC
Provisions made subsequent to the Startup Day allow a sale for other
consideration and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

          (c) The Servicer may write-off any Second Lien Mortgage Loan that has
been Delinquent for a period of 180 days or more if the Servicer determines that
any amount that could be recovered on such Mortgage Loan would be less than the
cost required to achieve such recovery.

     Section 3.14 Due-on-Sale Clauses; Assumption and Substitution Agreements.

     When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance
or prospective conveyance, exercise its rights to accelerate the maturity of the
related Mortgage Loan under any "due-on-sale" clause contained in the related
Mortgage or Mortgage Note; provided, however, that the Servicer shall not
exercise any such right if the "due-on-sale" clause, in the reasonable belief of
the Servicer, is not enforceable under applicable law. An Opinion of Counsel at
the expense of the Servicer (which expense shall constitute a Servicing Advance)
delivered to the Trustee and the Depositor to the foregoing effect shall
conclusively establish the reasonableness of such belief. In such event, the
Servicer shall make reasonable efforts to enter into an assumption and
modification agreement with the Person to whom such property has been or is
about to be conveyed, pursuant to which such Person becomes liable under the
Mortgage Note and, unless prohibited by applicable law or the Mortgage, the
Mortgagor remains liable thereon. If the foregoing is not permitted under
applicable law, the Servicer is authorized to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as Mortgagor and
becomes liable under the Note. In addition to the foregoing, the Servicer shall
not be required to enforce any "due-on-sale" clause if, in the reasonable
judgment of the Servicer, entering into an assumption and modification agreement
with a person to whom such Mortgaged Property shall be conveyed and releasing
the original Mortgagor from liability would be in the best interests of the
Certificateholders. The Mortgage Loan, as assumed, shall conform in all respects
to the

                                       86

<PAGE>

requirements, representations and warranties of this Agreement. The Servicer
shall notify the Trustee that any such assumption or substitution agreement has
been completed by forwarding to the Trustee (or the Custodian, as the case may
be) the original copy of such assumption or substitution agreement (indicating
the Mortgage File to which it relates) which copy shall be added by the Trustee
(or the Custodian, as the case may be) to the related Mortgage File and which
shall, for all purposes, be considered a part of such Mortgage File to the same
extent as all other documents and instruments constituting a part thereof. The
Servicer shall be responsible for recording any such assumption or substitution
agreements. In connection with any such assumption or substitution agreement,
the Monthly Payment on the related Mortgage Loan shall not be changed but shall
remain as in effect immediately prior to the assumption or substitution, the
stated maturity or outstanding principal amount of such Mortgage Loan shall not
be changed nor shall any required monthly payments of principal or interest be
deferred or forgiven. Any fee collected by the Servicer for consenting to any
such conveyance or entering into an assumption or substitution agreement shall
be retained by or paid to the Servicer as additional servicing compensation.

     Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

     Section 3.15 Notification of Adjustments.

     On each Adjustment Date, the Servicer shall make Mortgage Interest Rate
adjustments for each Mortgage Loan in compliance with the requirements of the
related Mortgage and Mortgage Note and Applicable Regulations. The Servicer
shall execute and deliver the notices required by each Mortgage and Mortgage
Note and Applicable Regulations regarding Mortgage Interest Rate adjustments.
The Servicer also shall provide timely notification to the Trustee of all
applicable data and information regarding such Mortgage Interest Rate
adjustments and the Servicer's methods of implementing such Mortgage Interest
Rate adjustments. Upon the discovery by the Servicer or the Trustee that the
Servicer has failed to adjust or has incorrectly adjusted a Mortgage Interest
Rate or a Monthly Payment pursuant to the terms of the related Mortgage Note and
Mortgage, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any interest loss caused
thereby without reimbursement therefor; provided, however, the Servicer shall be
held harmless with respect to any Mortgage Interest Rate adjustments made by any
servicer prior to the Servicer. Under no circumstances shall the Trustee be
responsible for monitoring or recalculating any Mortgage Interest Rate
adjustment provided by the servicer.

     Section 3.16 Optional Purchases of Mortgage Loans by Servicer.

     The Servicer (or an affiliate of the Servicer) may, at its option, purchase
a Mortgage Loan or REO Property which becomes 120 or more days Delinquent or for
which the Servicer has accepted a deed in lieu of foreclosure, during the period
commencing on the first day of the calendar quarter succeeding the calendar
quarter in which the Initial Delinquency Date occurred with respect to such
Mortgage Loan and ending on the last Business Day of such calendar quarter. If
the Servicer (or an affiliate of the Servicer) does not exercise its purchase
right with respect to a Mortgage Loan during the period specified in the
preceding sentence, such Mortgage Loan shall thereafter again become eligible
for purchase pursuant to the preceding sentence only after the Mortgage Loan
ceases to be 120 days or more Delinquent and thereafter becomes 120 days
Delinquent again. The "Initial Delinquency Date" of a Mortgage Loan shall mean
the date on which the Mortgage Loan first became 120 days Delinquent. Prior to
repurchase pursuant to this Section 3.16, the Servicer shall be required to
continue to make monthly advances pursuant to Section 4.07. The Servicer shall
not use any procedure in selecting Mortgage Loans

                                       87

<PAGE>

to be repurchased which is materially adverse to the interests of the
Certificateholders. The Servicer shall purchase such (i) delinquent Mortgage
Loan at a price equal to the Principal Balance of the Mortgage Loan plus accrued
interest thereon at the Mortgage Interest Rate from the date to which interest
has last been paid to the Trust Fund to the date of purchase plus any
unreimbursed Servicing Advances and Advances or (ii) REO Property at its fair
market value as determined in good faith by the Servicer. Any such repurchase of
a Mortgage Loan or REO Property pursuant to this Section 3.16 shall be
accomplished by delivery to the Trustee for deposit in the Distribution Account
of the amount of the purchase price. The Trustee shall immediately effectuate
the conveyance of such delinquent Mortgage Loan or REO Property to the Servicer
to the extent necessary, including the prompt delivery of all necessary
documentation provided by it to the Servicer.

     Section 3.17 Trustee to Cooperate; Release of Files.

          (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such Mortgage Loan through foreclosure or otherwise, or the
receipt by the Servicer of a notification that payment in full will be escrowed
in a manner customary for such purposes), the Servicer shall deliver to the
Custodian two executed copies of a completed "Request for Release" in the form
of Exhibit E. Upon receipt of such Request for Release of Documents, the
Custodian shall promptly release the related Mortgage File, in trust to (i) the
Servicer, or (ii) such other party identified in the related Request for
Release. Upon any such payment in full, or the receipt of such notification that
such funds have been placed in escrow, the Servicer shall direct the Trustee in
writing to execute an instrument of satisfaction (or assignment of Mortgage
without recourse, representation or warranty) regarding the Mortgaged Property
relating to such 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 payment in full, it being understood and agreed that
no expense incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Collection Account.
In lieu of executing any such satisfaction or assignment, as the case may be,
the Servicer may prepare and submit to the Trustee a satisfaction (or assignment
without recourse, representation or warranty if requested by the Person or
Persons entitled thereto) in form for execution by the Trustee with all
requisite information completed by the Servicer; in such event, the Trustee
shall execute and acknowledge such satisfaction or assignment, as the case may
be, and deliver the same with the related Mortgage File, as aforesaid.

          (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any insurance policy relating
to a Mortgage Loan, the Trustee shall (except in the case of the payment or
liquidation pursuant to which the related Mortgage File is released to an escrow
agent or an employee, agent or attorney of the Trustee), upon written request of
the Servicer and delivery to the Custodian of two executed copies of a "Request
for Release" in the form of Exhibit E signed by a Servicing Officer, release the
related Mortgage File to the Servicer and shall execute such documents as shall
be necessary to the prosecution of any such proceedings, including, without
limitation, an assignment without recourse, representation or warranty of the
related Mortgage to the Servicer. Such receipt shall obligate the Servicer to
return the Mortgage File to the Custodian when the need therefor by the Servicer
no longer exists unless the Mortgage Loan shall be liquidated, in which case,
upon receipt of a Request for Release evidencing such liquidation, the receipt
shall be released by the Custodian to the Servicer.

          (c) Subject to Section 3.01, the Servicer shall have the right to
accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, (iii) removal, demolition or division of properties
subject to Mortgages and (iv) second mortgage subordination agreements. No
application for approval shall be considered by the Servicer unless: (w) it has
received an Opinion of

                                       88

<PAGE>

Counsel, addressed to the Trustee (which opinion shall not be an expense of the
Trustee or the Trust Fund) that such sale, disposition, substitution,
acquisition or contribution will not affect adversely the status of any REMIC
constituting part of the Trust Fund as a REMIC or cause any REMIC constituting
part of the Trust Fund to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions; (x) the provisions of the
related Mortgage Note and Mortgage have been complied with; (y) the Combined
Loan-to-Value Ratio and debt-to-income ratio after any release does not exceed
the maximum Combined Loan-to-Value Ratio and debt-to-income ratio established in
accordance with the underwriting standards of the Mortgage Loans; and (z) the
lien priority of the related Mortgage is not affected. Upon receipt by the
Trustee of a Servicing Officer's certificate setting forth the action proposed
to be taken in respect of a particular Mortgage Loan and certifying that the
criteria set forth in the immediately preceding sentence have been satisfied,
the Trustee shall execute and deliver to the Servicer the consent or partial
release so requested by the Servicer. A proposed form of consent or partial
release, as the case may be, shall accompany any Servicing Officer's certificate
delivered by the Servicer pursuant to this paragraph.

     Section 3.18 Servicing Compensation.

     As compensation for its activities hereunder, the Servicer shall be
entitled to retain the amount of the Servicing Fee with respect to each Mortgage
Loan (including REO Properties). The Servicer shall be entitled to retain
additional servicing compensation in the form of release fees, bad check
charges, assumption fees, modification or extension fees, late payment charges,
customary real-estate referral fees, Prepayment Interest Excess or any other
service-related fees, Insurance Proceeds and Liquidation Proceeds not required
to be deposited in the Collection Account or the Distribution Account and
similar items, to the extent collected from Mortgagors. For so long as Litton is
the servicer of the Mortgage Loans, Litton will receive the Litton Servicing Fee
and the Holders of the Class CE-2 Certificates will receive the Excess Servicing
Fee.

     Section 3.19 Annual Statement as to Compliance.

     The Servicer shall deliver or cause to be delivered, and shall cause each
Subservicer engaged by such Servicer to deliver or cause to be delivered to the
Depositor, the Rating Agencies and the Trustee on or before March 15th of each
calendar year, commencing in 2008, an Officer's Certificate stating, as to each
signatory thereof, that (i) a review of the activities of such Servicer or
Subservicer, as applicable, during the preceding calendar year and of
performance under this Agreement, or the applicable Subservicing Agreement, as
the case may be, has been made under such officers' supervision, and (ii) to the
best of such officers' knowledge, based on such review, such Servicer or
Subservicer, and each Subcontractor utilized by such Servicer and determined by
such Servicer to be "participating in a servicing function" within the meaning
of Item 1122 of Regulation AB, as applicable, has fulfilled all of its
obligations under this Agreement in all material respects throughout such year,
or, if there has been a failure to fulfill any such obligation in any material
respect, specifying each such failure known to such officers and the nature and
status thereof. Promptly after receipt of such Officer's Certificate, the
Depositor shall review such Officer's Certificate and, if applicable, consult
with the applicable Servicer as to the nature of any defaults by such Servicer
or any related Subservicer in the fulfillment of any such Servicer's or any
related Subservicer's obligations. The obligations of a Servicer or Subservicer
under this Section apply to each Servicer that serviced a Mortgage Loan during
the applicable period, whether or not such Servicer or Subservicer is acting as
a Servicer or Subservicer at the time such Officer's Certificate is required to
be delivered. For purposes of (ii) above, the Servicer or Subservicer will be
entitled to rely reasonably upon a certification of any Subcontractor not
affiliated with the Servicer or Subservicer. Notwithstanding anything to the
contrary set forth herein, the statement required under this Section 3.19 with
respect to any Subservicer or Subcontractor shall not be required to

                                       89

<PAGE>

be delivered with respect to any year in which an annual report on Form 10-K for
the Trust is not required to be filed pursuant to the Exchange Act.

"participating in a servicing function" within the meaning of Item 1122 of
Regulation AB, to deliver, each at its own expense, to the Depositor and the
Trustee, with a copy to the Rating Agencies, a report on an assessment of
compliance with the Servicing Criteria that contains (A) a statement by such
party of its responsibility for assessing compliance with the Servicing Criteria
applicable to it, (B) a statement that such party used the Servicing Criteria to
assess compliance with the applicable Servicing Criteria, (C) such party's
assessment of compliance with the applicable Servicing Criteria as of and for
the period ending the end of the fiscal year covered by the Form 10-K required
to be filed pursuant to Section 3.29, setting forth any material instance of
noncompliance with the applicable Servicing Criteria, and (D) a statement that a
registered public accounting firm has issued an attestation report on such
Person's assessment of compliance with the applicable Servicing Criteria as of
and for such period. Each such assessment of compliance report shall be
delivered to the Depositor and shall address each of the Servicing Criteria
applicable to such party specified on a certification substantially in the form
of Exhibit N hereto delivered to the Depositor on the Closing Date.
Notwithstanding anything to the contrary set forth herein, the statements and

Subcontractor shall not be required to be delivered with respect to any year in
which an annual report on Form 10-K for the Trust is not required to be filed

Item 1122 of Regulation AB, to, cause, and not later than March 15 of each
calendar year in which the Depositor's annual report on Form 10-K with respect
to the transactions contemplated by this Agreement is required to be filed in

Day), the Trustee shall cause, each at its own expense, a registered public
accounting firm (which may also render other services to such party) and that is
a member of the American Institute of Certified Public Accountants to furnish a
report to the Trustee and the Depositor, with a copy to the Rating Agencies, to
the effect that (i) it has obtained a representation regarding certain matters
from the management of such Person, which includes an assertion that such Person
has complied with the Servicing Criteria and (ii) on the basis of an examination
conducted by such firm in accordance with standards for attestation engagements
issued or adopted by the PCAOB, it is expressing an opinion as to whether such
Person's compliance with the Servicing Criteria was fairly stated in all
material respects, or it cannot express an overall opinion regarding such
Person's assessment of compliance with the Servicing Criteria. In the event that
an overall opinion cannot be expressed, such registered public accounting firm
shall state in such report why it was unable to express

                                       90

<PAGE>

such an opinion. Such report must be available for general use and not contain
restricted use language. Each such related accountant's attestation report shall

Securities Act and the Exchange Act. Notwithstanding anything to the contrary
set forth herein, the statements and attestations required under this Section

the Trust is not required to be filed pursuant to the Exchange Act.

completed, to be subject of the assessment of compliance to be delivered
pursuant to Section 3.20(a) by each of them (and in the case of the Servicer,
each Subservicer engaged by such Servicer and in the case of the Servicer and
Trustee each Subcontractor utilized by the Servicer or the Trustee, as
applicable, and determined by such Servicer or the Trustee, as applicable,
pursuant to be "participating in a servicing function" within the meaning of
Item 1122 of Regulation AB).

Mortgage Loans.

     The Servicer shall provide to the Trustee, Certificateholders that are
federally insured savings and loan associations, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of each of the

required by applicable state and federal regulations) access to the
documentation regarding the Mortgage Loans, such access being afforded without
charge but only upon reasonable request and during normal business hours at the
offices of the Servicer designated by it.

     Section 3.22 Reserved.

     Section 3.23 Obligations of the Servicer in Respect of Compensating
Interest.

     Not later than the close of business on each Servicer Remittance Date, the
Servicer shall deliver to the Trustee for deposit in the Distribution Account an
amount ("Compensating Interest") equal to the lesser of (A) the aggregate of the
Prepayment Interest Shortfalls on the Mortgage Loans for the related
Distribution Date resulting from Principal Prepayments in full on the Mortgage
Loans during the related Prepayment Period and (B) 50% of the aggregate
Servicing Fee for the related Collection Period. The Servicer shall apply
Compensating Interest to offset any Prepayment Interest Shortfalls on the
Mortgage Loans. The Servicer shall not have the right to reimbursement for any
amounts remitted to the Trustee in respect of Compensating Interest. Such
amounts so remitted shall be included in the Available Funds and distributed
therewith on the next Distribution Date. The Servicer shall not be obligated to
pay Compensating Interest with respect to Prepayment Interest Shortfalls or
Relief Act Interest Shortfalls.

     Section 3.24 Obligations of the Servicer in Respect of Mortgage Interest
Rates and Monthly Payments.

     In the event that a shortfall in any collection on or liability with
respect to any Mortgage Loan results from or is attributable to adjustments to
Mortgage Interest Rates, Monthly Payments or Principal Balances that were made
by the Servicer in a manner not consistent with the terms of the related
Mortgage Note and this Agreement, the Servicer, upon discovery or receipt of
notice thereof, immediately shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any such shortfall and
shall indemnify and hold harmless the Trust Fund, the Trustee, the Depositor and
any

                                       91

<PAGE>

successor servicer in respect of any such liability. Such indemnities shall
survive the termination or discharge of this Agreement.

     Section 3.25 Investment of Funds in the Collection Account and the
Distribution Account.

          (a) The Servicer with respect to the Collection Account and the
Trustee with respect to the Distribution Account may direct any depository
institution maintaining the Collection Account or Distribution Account to invest
the funds in the Collection Account or the Distribution Account, as applicable,
in one or more Permitted Investments bearing interest or sold at a discount, and
maturing, unless payable on demand, (i) no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement, if a Person other than the Trustee
is the obligor thereon, and (ii) no later than the date on which such funds are
required to be withdrawn from such account pursuant to this Agreement, if the
Trustee is the obligor thereon. In the absence of such direction, funds in the
Collection Account and the Distribution Account shall remain uninvested. All
such Permitted Investments shall be held to maturity, unless payable on demand.
Any investment of funds in the Collection Account or the Distribution Account,
shall be made in the name of the Trustee or the Servicer, as applicable (in its
capacity as such), or in the name of a nominee of the Trustee. Upon the
occurrence of a Servicer Event of Termination, the Trustee shall be entitled to
sole possession (except with respect to investment direction of funds held in
the Collection Account) over each such investment and the income thereon, and
any certificate or other instrument evidencing any such investment shall be
delivered directly to the Trustee or its agent, together with any document of
transfer necessary to transfer title to such investment to the Trustee or its
nominee. In the event amounts on deposit in the Collection Account are at any
time invested in a Permitted Investment payable on demand, the Trustee shall at
the direction of the Servicer:

          (x)  consistent with any notice required to be given thereunder,
               demand that payment thereon be made on the last day such
               Permitted Investment may otherwise mature hereunder in an amount
               equal to the lesser of (1) all amounts then payable thereunder
               and (2) the amount required to be withdrawn on such date; and

          (y)  demand payment of all amounts due thereunder promptly upon
               determination by a Responsible Officer of the Trustee that such
               Permitted Investment would not constitute a Permitted Investment
               in respect of funds thereafter on deposit in the Collection
               Account.

          (b) All income and gain realized from the investment of funds in the
Collection Account shall be for the benefit of the Servicer. All income and gain
realized from the investment of funds in the Distribution Account shall be for
the benefit of the Trustee. The Servicer shall deposit in the Collection Account
and the Trustee shall deposit into the Distribution Account the amount of any
loss incurred in respect of any such Permitted Investment made with funds in
such account immediately upon realization of such loss.

          (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v),
upon the request of the Holders of Certificates representing more than 50% of
the Voting Rights allocated to any Class of Certificates, shall take such action
as may be appropriate to enforce such payment or performance, including the
institution and prosecution of appropriate proceedings.

                                       92
<PAGE>

     The Trustee shall not in any way be held liable by reason of any
insufficiency in any Account held by the Trustee resulting from any investment
loss on any Permitted Investment included therein (except to the extent that the
Trustee is the obligor and has defaulted thereon).

     Section 3.26 Liability of Servicer; Indemnification.

          (a) Subject to clause (b) below and Section 6.03, the Servicer (or its
successor hereunder (except the Trustee if it is required to succeed the
Servicer hereunder)) indemnifies and holds the Trustee, the Seller, the
Depositor and each Certificateholder harmless against any and all claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Trustee, the
Depositor and any Certificateholder may sustain in any way related to the
failure of the Servicer to perform its duties and service the Mortgage Loans in
compliance with the Servicing Standards. The Servicer shall immediately notify
the Trustee, the Depositor and each Certificateholder if a claim is made that
may result in such claims, losses, penalties, fines, forfeitures, legal fees or
related costs, judgments, or any other costs, fees and expenses, and the
Servicer shall assume (with the consent of the Trustee) the defense of any such
claim and pay all expenses in connection therewith, including reasonable counsel
fees, and promptly pay, discharge and satisfy any judgment or decree which may
be entered against the Servicer, Trustee, the Depositor and/or Certificateholder
in respect of such claim. The provisions of this Section 3.26 shall survive the
termination of this Agreement, the termination or resignation of the Servicer or
the Trustee and the payment of the outstanding Certificates.

          (b) None of the Depositor, the Seller, the Servicer, or any of the
directors, officers, employees or agents of the Depositor, the Seller or the
Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken, or for refraining from the taking of
any action, in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositor, the
Seller or the Servicer or any such Person against any breach of warranties or
representations made herein, or against any specific liability imposed on the
Servicer for a breach of the Servicing Standard, or against any liability which
would otherwise be imposed by reason of its respective willful misfeasance, bad
faith, fraud or negligence in the performance of its duties or by reasons of
negligent disregard of its respective obligations or duties hereunder.

     The Depositor, the Servicer, the Seller and any director, officer, employee
or agent of the Depositor, the Seller or the Servicer, may rely in good faith on
any document of any kind which, prima facie, is properly executed and submitted
by any appropriate Person with respect to any matters arising hereunder. The
Depositor, the Servicer, the Seller, and any director, officer, employee or
agent of the Depositor, the Seller or the Servicer shall be indemnified and held
harmless by the Trust Fund against any loss, liability or expense incurred in
connection with any legal action relating to this Agreement or the Certificates,
other than any loss, liability or expense incurred in connection with any legal
action incurred by reason of its respective misfeasance, bad faith, fraud or
negligence, a breach of a representation or warranty hereunder or (in the case
of the Servicer) a breach of the Servicing Standard in the performance of its
respective duties or by reason of negligent disregard of its respective
obligations or duties hereunder. Neither the Depositor, the Seller nor the
Servicer shall be under any obligation to appear in, prosecute or defend any
legal action unless such action is related to its respective duties under this
Agreement and in its opinion does not expose it to any expense or liability;
provided, however, that the Depositor, the Seller or the Servicer may in its
discretion undertake any action related to its obligations hereunder 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.

Servicer shall file the reports of foreclosure and abandonment of any Mortgaged
Property required by Section 6050J of the Code with the Internal Revenue Service

the party listed on Exhibit S to the Trustee and the Depositor in the manner
provided in the following paragraph; provided that such information is provided
to the Trustee no later than the fifth Business Day immediately following the
related Distribution Date. The Trustee shall not be responsible for determining
what information is required to be filed on Form 10-D (unless such information
is specific to the Trustee, in which case the Trustee will be responsible for
making such a determination) or for any filing that is not made on a timely
basis in accordance with Regulation AB in the event that such information is not
delivered to the Trustee on or prior to the first Business Day immediately
following the related Determination Date. The Trustee will have no duty or
liability for any failure hereunder to determine or prepare any Additional Form
10-D Disclosure, except as set forth in the next paragraph.

     As set forth on Exhibit S hereto, within 5 calendar days after the related
Distribution Date, the parties described on Exhibit S shall be required to
provide to the Trustee and to the Depositor, to the extent known by a
responsible officer thereof, in EDGAR-compatible format, or in such other format
as otherwise agreed upon by the Trustee and such party, the form and substance
of any Additional Form 10-D Disclosure, if applicable, together with an
Additional Disclosure Notification in the form of Exhibit U hereto (an
"Additional Disclosure Notification") and the Depositor will approve, as to form
and

                                       94

<PAGE>

substance, or disapprove, as the case may be, the inclusion of the Additional
Form 10-D Disclosure on Form 10-D. The Trustee has no duty under this Agreement
to monitor or enforce the performance by the parties listed on Exhibit S (other
than with respect to the Trustee) of their duties under this paragraph or
proactively solicit or procure from such parties any Additional Form 10-D
Disclosure information.

     After preparing the Form 10-D, the Trustee shall forward electronically a
copy of the Form 10-D to the Depositor and the Servicer. Within two Business
Days after receipt of such copy, but no later than the 12th calendar day after
the Distribution Date, the Depositor and the Servicer shall notify the Trustee
in writing (which may be furnished electronically) of any changes to or approval
of such Form 10-D and the Depositor shall cause a duly authorized representative
of the Servicer to sign the Form 10-D. If a Form 10-D cannot be filed on time or
if a previously filed Form 10-D needs to be amended, the Trustee will follow the
procedures set forth in Section 3.29(h). Promptly (but no later than one
Business Day) after filing with the Commission, the Trustee will make available
on its internet website a final executed copy of each Form 10-D filed by the
Trustee. Each party to this Agreement acknowledges that the performance by the
Trustee of its duties under this Section 3.29(b) related to the timely
preparation, arrangement for execution and filing of Form 10-D is contingent
upon such parties strictly observing all applicable deadlines in the performance
of their duties under this Section 3.29(b). The Trustee shall not have any
liability for any loss, expense, damage or claim arising out of or with respect
to any failure to properly prepare, execute and/or timely file such Form 10-D,
where such failure results from the Trustee's inability or failure to obtain or
receive, on a timely basis, any information from any other party hereto or any
Servicing Function Participant of any party hereto needed to prepare, arrange
for execution or file such Form 10-D, not resulting from its own negligence, bad
faith or willful misconduct.

     On or prior to the 90th day after the end of each year commencing in 2008
(or such earlier date as may be required by the Exchange Act and the Rules and
Regulations of the Commission), the Trustee shall file a Form 10-K. Such Form
10-K shall include the information listed on Exhibit T and each party shall
provide the information they are responsible for pursuant to Exhibit T. Such
Form 10-K shall include as exhibits (to the extent they have been delivered to
the Trustee in accordance with the timeframes contained within this agreement)
(i) each annual statement of compliance described under Section 3.19 of this
Agreement and (ii) the annual report on assessments of compliance and annual
independent public accountant's servicing reports described under Section 3.20
of this Agreement, in each case to the extent they have been timely delivered to
the Trustee. Promptly upon receipt by the Servicer of (i)(A) any Officer's
Certificate relating to the Trustee's or Subservicer's annual statement as to
compliance delivered pursuant to Section 3.19 of this Agreement and (B) any
annual report on assessment of compliance and annual independent public
accountant's servicing report, pursuant to Section 3.20 of this Agreement, the
Servicer shall review such Officer's Certificate's and reports. As part of the
Form 10-K required to be filed pursuant to this Section 3.29, the Servicer shall
include each such annual statement as to compliance, annual report on assessment
of servicing compliance with servicing criteria and annual independent public
accountant's servicing report required to be delivered under this Agreement. In
addition, if there is any material instance of non-compliance disclosed in a
report delivered pursuant to Section 3.19 or 3.20 of this Agreement, a
description of each material instance of non-compliance shall be provided to the
Trustee and the Trustee shall include such disclosure in the Form 10-K required
to be filed pursuant to this Section 3.29. If the Trustee is unable to file such
Form 10-K by the applicable due date, the Trustee shall prepare for execution by
the Servicer and file a Form 12b-25 not later than one Business Day following
the due date from such Form 10-K. Within 5 days following the filing of such
Form 12b-25, the Trustee shall prepare and file the related Form 10-K. The Form
10-K shall also include a certification in the form attached hereto as Exhibit
P-3, with such changes as may be necessary or appropriate as a result of changes
promulgated by the Commission (the "Sarbanes Certification"), which shall,
except as described below, be signed by the senior officer in charge of the
servicing function of the Servicer. The Trustee shall have no liability with
respect to any failure to

                                       95

<PAGE>

properly prepare or file such periodic reports resulting from or relating to the
Trustee's inability or failure to obtain any information not resulting from its
own negligence, willful misconduct or bad faith. If the Servicer's report on
assessment of compliance with Servicing Criteria is not included as an exhibit
to such Form 10-K, the Servicer shall provide disclosure that such report is not
included and an explanation why such report is not included. If any such
registered public accounting firm attestation report is not included as an
exhibit to such Form 10-K, the Reporting Servicer to which such attestation
relates shall provide disclosure that such report is not included and an
explanation why such report is not included.

     Any disclosure or information in addition to the attachments listed above
that is required to be included on Form 10-K ("Additional Form 10-K Disclosure")
shall be reported by the parties set forth on Exhibit T to the Depositor and the
Trustee [and directed and approved by the Depositor pursuant to the following
paragraph], and the Trustee will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-K Disclosure, except as
set forth in the next paragraph.

     As set forth on Exhibit T hereto, no later than March 15 of each year,
commencing in 2008, (i) the parties described on Exhibit T shall be required to
provide to the Trustee and to the Depositor, to the extent known by a
responsible officer thereof, in EDGAR-compatible format, or in such other format
as otherwise agreed upon by the Trustee and such party, the form and substance
of any Additional Form 10-K Disclosure, if applicable, together with an
Additional Disclosure Notification, and (ii) the Depositor will approve, as to
form and substance, or disapprove, as the case may be, the inclusion of the
Additional Form 10-K Disclosure on Form 10-K. The Trustee has no duty under
this Agreement to monitor or enforce the performance by the parties listed on
Exhibit T (other than with respect to the Trustee) of their duties under this
paragraph or proactively solicit or procure from such parties any Additional
Form 10-K Disclosure information. The Depositor will be responsible for any
reasonable fees and expenses assessed or incurred by the Trustee in connection
with including any Additional Form 10-K Disclosure on Form 10-K pursuant to this
paragraph.

     After preparing the Form 10-K, the Trustee shall forward electronically a
copy of the Form 10-K to the Depositor and the Servicer. Within three Business
Days after receipt of such copy, but no later than March 25th, the Servicer
shall notify the Trustee in writing (which may be furnished electronically) of
any changes to or approval of such Form 10-K and shall cause the senior officer
of the Servicer in charge of the securitization function to return a signed copy
of the Form 10-K to the Trustee. If a Form 10-K cannot be filed on time or if a
previously filed Form 10-K needs to be amended, the Trustee will follow the
procedures set forth in Section 3.29(h). Promptly (but no later than one
Business Day) after filing with the Commission, the Trustee will make available
on its internet website a final executed copy of each Form 10-K filed by the
Trustee. The parties to this Agreement acknowledge that the performance by the
Trustee of its duties under this Section 3.29(c) related to the timely
preparation, arrangement for execution and filing of Form 10-K is contingent
upon such parties strictly observing all applicable deadlines in the performance
of their duties under this Section 3.29(c), Section 3.29(d), Section 3.19 and
Section 3.20. The Trustee shall not have any liability for any loss, expense,
damage or claim arising out of or with respect to any failure to properly
prepare, arrange for execution and/or timely file such Form 10-K, where such
failure results from the Trustee's inability or failure to obtain or receive, on
a timely basis, any information from any other party hereto or any Servicing
Function Participant needed to prepare, arrange for execution or file such Form
10-K, not resulting from its own negligence, bad faith or willful misconduct.

     In connection with the Form 10-K, the Trustee shall sign a back-up
certification (in the form attached hereto as Exhibit P-5) for the benefit of
the Servicer and its officers, directors and Affiliates. Each such back-up
certification shall be delivered to the Servicer no later than March 15th of
each year (or if such day is not a Business Day, the immediately preceding
Business Day) and the Servicer shall

                                       96

<PAGE>

deliver the Sarbanes Certification to be filed with each Form 10-K to the
Trustee and the Depositor no later than March 15th of each year (or if such day
is not a Business Day, the immediately preceding Business Day).

     In the event that prior to the filing date of the Form 10-K in March of
each year, if any party hereto has actual knowledge of information material to
the Sarbanes Certification, that party shall promptly notify the Servicer and
each of the other parties signing the certifications. In addition, (i) the
Trustee shall, subject to Sections 8.01 and 8.02 hereof, indemnify and hold
harmless the Depositor and the Servicer and any of their officers, directors,
employees, agents and Affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments and other costs and expenses arising out of or based upon any
breach of the Trustee's obligations under this Section 3.29, the Trustee's
negligence, bad faith or willful misconduct in connection therewith or any
material misstatement in the Trustee's certification and (ii) the Servicer shall
indemnify and hold harmless the Depositor and the Trustee and any of their
respective officers, directors and Affiliates from and against any actual
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and expenses (other than
punitive damages) arising out of or based upon any breach of the Servicer's
obligations under Section 3.29 or any material misstatement or omission in the
Sarbanes Certification. If the indemnification provided for in the preceding
sentence is unavailable or insufficient to hold harmless any indemnified party,
then (i) the Trustee agrees in connection with a breach of the Trustee's
obligations under this Section 3.29 or the Trustee's negligence, bad faith or
willful misconduct in connection therewith that it shall contribute to the
amount paid or payable by the indemnified party as a result of the losses,
claims, damages or liabilities of the indemnified party, on the one hand, and
the Trustee, on the other, and (ii) the Servicer agrees that it shall contribute
to the amount paid or payable by such indemnified party as a result of the
losses, claims, damages or liabilities of such indemnified party in such
proportion as is appropriate to reflect the relative fault of such indemnified
party, on the one hand, and the Servicer, on the other, in connection with a
breach of the Servicer's obligations under this Section 3.29.

          (c) Within four (4) Business Days after the occurrence of an event
requiring disclosure on Form 8-K (each such event, a "Reportable Event"), and if
requested by the Depositor, the Trustee shall prepare and file on behalf of the
Trust any Form 8-K, as required by the Exchange Act, provided that the
Depositor shall file the initial Form 8-K in connection with the issuance of the
Certificates. Any disclosure or information related to a Reportable Event or
that is otherwise required to be included on Form 8-K other than the initial
Form 8-K ("Form 8-K Disclosure Information") shall be reported by the parties
set forth on Exhibit R to the Depositor and the Trustee (unless such item is
specific to the Trustee, in which case the Trustee will be deemed to have
notice) and directed and approved by the Depositor pursuant to the following
paragraph, and the Trustee will have no duty or liability for any failure
hereunder to determine or prepare any Form 8-K Disclosure Information or any
Form 8-K, except as set forth in the next paragraph.

     As set forth on Exhibit R hereto, for so long as the Trust is subject to
the Exchange Act reporting requirements, no later than the close of business
(New York City time) on the 2nd Business Day after the occurrence of a
Reportable Event (i) the parties described on Exhibit R shall be required to
provide to the Trustee and to the Depositor, to the extent known by a
responsible officer thereof, in EDGAR-compatible form, or in such other form as
otherwise agreed upon by the Trustee and such party, the form and substance of
any Form 8-K Disclosure Information, if applicable, together with an Additional
Disclosure Notification in the form attached hereto as Exhibit U and (ii) the
Depositor will approve, as to form and substance, or disapprove, as the case may
be, the inclusion of the Form 8-K Disclosure Information. The Trustee has no
duty under this Agreement to monitor or enforce the performance by the parties
listed on Exhibit R (other than with respect to the Trustee) of their duties
under this paragraph or proactively solicit

                                       97

<PAGE>

or procure from such parties any Form 8-K Disclosure information. The Depositor
will be responsible for any reasonable fees and expenses assessed or incurred by
the Trustee in connection with including any Form 8-K Disclosure Information on
Form 8-K pursuant to this paragraph.

     After preparing the Form 8-K, the Trustee shall, upon request, forward
electronically a copy of the Form 8-K to the Depositor and the Servicer.
Promptly, but no later than the close of business on the third Business Day
after the Reportable Event, the Servicer shall notify the Trustee in writing
(which may be furnished electronically) of any changes to or approval of such
Form 8-K and shall cause a duly authorized representative of the Servicer to
return a signed copy of each Form 8-K to the Trustee. If a Form 8-K cannot be
filed on time or if a previously filed Form 8-K needs to be amended, the Trustee
will follow the procedures set forth in Section 3.29(g). Promptly (but no later
than one Business Day) after filing with the Commission, the Trustee will make
available on its internet website a final executed copy of each Form 8-K filed
by it. The parties to this Agreement acknowledge that the performance by the
Trustee of its duties under this Section 3.29(d) related to the timely
preparation, arrangement for execution and filing of Form 8-K is contingent upon
such parties strictly observing all applicable deadlines in the performance of
their duties under this Section 3.29(d). The Trustee shall not have any
liability for any loss, expense, damage, claim arising out of or with respect to
any failure to properly prepare, arrange for execution and/or timely file such
Form 8-K, where such failure results from the Trustee's inability or failure to
obtain or receive, on a timely basis, any information from any other party
hereto (unless such item is specific to the Trustee, in which case the Trustee
will be deemed to have notice) or any Servicing Function Participant needed to
prepare, arrange for execution or file such Form 8-K, not resulting from its own
negligence, bad faith or willful misconduct.

          (d) Upon any filing with the Commission, the Trustee shall promptly
deliver to the Depositor and the Servicer a copy of any executed report,
statement or information.

          (e) The obligations set forth in paragraphs (a) through (c) of this
Section shall only apply with respect to periods for which reports are required
to be filed with respect to the Trust under the Exchange Act. Prior to January
30 of the first year in which the Trustee is able to do so under applicable law,
the Trustee shall file a Form 15 Suspension Notification with respect to the
Trust. At any time after the filing of a Form 15 Suspension Notification, if the
number of Certificateholders of record exceeds the number set forth in Section
15(d) of the Exchange Act or the regulations promulgated pursuant thereto which
would cause the Trust to again become subject to the reporting requirements of
the Exchange Act, the Trustee shall recommence preparing and filing reports on
Form 10-K and Form 10-D as required pursuant to this Section 3.29 and the
parties hereto shall have the obligations set forth in this Section.

     In the event that the Trustee is unable to timely file with the Commission
all or any required portion of any Form 8-K, 10-D or 10-K required to be filed
by this Agreement because required disclosure information was either not
delivered to it or delivered to it after the delivery deadlines set forth in
this Agreement or for any other reason, the Trustee will promptly notify the
Depositor. In the case of Form 10-D and 10-K, the parties to this Agreement will
cooperate to prepare and file a Form 12b-25 and a 10-D/A and 10-K/A as
applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form
8-K, the Trustee will, upon receipt of all required Form 8-K Disclosure
Information and upon the approval and direction of the Depositor, include such
disclosure information on the next Form 10-D. In the event that any previously
filed Form 8-K, 10-D or 10-K needs to be amended in connection with any
Additional Form 10-D Disclosure (other than, in the case of Form 10-D, for the
purpose of restating any Monthly Statement), Additional Form 10-K Disclosure or
Form 8-K Disclosure Information, the Trustee will notify the Depositor and the
Servicer and such other parties to the transaction as are affected by such
amendment, and such parties will cooperate to prepare any necessary 8-K/A,
10-D/A or 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K, 10-D or
10-K shall be signed by a duly

                                       98

<PAGE>

authorized representative, or senior officer in charge of securitization, as
applicable, of the Servicer. The parties to this Agreement acknowledge that the
performance by the Trustee of its duties under this Section 3.29(g) related to
the timely preparation, arrangement for execution and filing of Form 15, a Form
12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent upon each such
party performing its duties under this Section. The Trustee shall not have any
liability for any loss, expense, damage, claim arising out of or with respect to
any failure to properly prepare, arrange for execution and/or timely file any
such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, where
such failure results from the Trustee's inability or failure to obtain or
receive, on a timely basis, any information from any other party hereto or any
Servicing Function Participant needed to prepare, arrange for execution or file
such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not
resulting from its own negligence, bad faith or willful misconduct.

          (f) For so long as reports are required to be filed with the
Commission under the Exchange Act with respect to the Trust, each of the
Depositor, the Trustee and the Servicer shall notify the Depositor, the Servicer
and the Trustee in writing of any litigation (material to Certificateholders) or
proceeding pending against such notifying person (or, in the case of the
Depositor, against the Depositor, or in the case of any Servicer, against the
Servicer or any Subservicer engaged by it), or any affiliations or relationships
that develop following the Closing Date between such notifying person, or in the
case of any Servicer, between the Servicer or any Subservicer engaged by it, and
any other party hereto or any originator, that may have to be reported on a Form
8-K, Form 10-K or Form 10-D with respect to the Trust.

     To the extent that, following the Closing Date, the Depositor certifies
that reports and certifications differing from those required under this Section
3.29 comply with the reporting requirements under the Exchange Act, the Trustee
and the Servicer hereby agree that they will reasonably cooperate to amend the
provisions of this Section 3.29 in order to comply with such amended reporting
requirements and such amendment of this Section 3.29. Any such amendment may
result in the reduction of the reports filed by the Depositor under the Exchange
Act. Notwithstanding the foregoing, the parties hereto shall not be obligated to
enter into any amendment pursuant to this Section 3.29 that adversely affects
its obligations and immunities under this Agreement.

     Section 3.30 Advance Facility.

          (a) The Servicer is hereby authorized to enter into a financing or
other facility (any such arrangement, an "Advance Facility"), the documentation
for which complies with Section 3.30(e) below, under which (1) the Servicer
assigns or pledges its rights under this Agreement to be reimbursed for any or
all Advances and/or Servicing Advances to (i) a Person, which may be a
special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing Person agrees to fund all the Advances and/or Servicing Advances
required to be made by the Servicer pursuant to this Agreement. No consent of
the Trustee, Certificateholders or any other party shall be required before the
Servicer may enter into an Advance Facility nor shall the Trustee or the
Certificateholders be a third party beneficiary of any obligation of an Advance
Financing Person to the Servicer. Notwithstanding the existence of any Advance
Facility under which an Advance Financing Person agrees to fund Advances and/or
Servicing Advances, (A) the Servicer (i) shall remain obligated pursuant to this
Agreement to make Advances and/or Servicing Advances pursuant to and as required
by this Agreement and (ii) shall not be relieved of such obligations by virtue
of such Advance Facility and

                                       99

<PAGE>

(B) neither the Advance Financing Person nor any Servicer's Assignee (as
hereinafter defined) shall have any right to proceed against or otherwise
contact any Mortgagor for the purpose of collecting any payment that may be due
with respect to any related Mortgage Loan or enforcing any covenant of such
Mortgagor under the related Mortgage Loan documents.

          (b) If the Servicer enters into an Advance Facility, the Servicer and
the related Advance Financing Person shall deliver to the Trustee at the address
set forth in Section 11.05 hereof a written notice (an "Advance Facility
Notice"), stating (a) the identity of the Advance Financing Person and (b) the
identity of the Person (the "Servicer's Assignee") that will, subject to Section
3.30(c) hereof, have the right to make withdrawals from the Collection Account
pursuant to Section 3.05 hereof to reimburse previously unreimbursed Advances
and/or Servicing Advances ("Advance Reimbursement Amounts"). Advance
Reimbursement Amounts (i) shall consist solely of amounts in respect of Advances
and/or Servicing Advances for which the Servicer would be permitted to reimburse
itself in accordance with Section 3.05 hereof, assuming the Servicer had made
the related Advance(s) and/or Servicing Advance(s) and (ii) shall not consist of
amounts payable to a successor Servicer in accordance with Section 3.05 hereof
to the extent permitted under Section 3.30(e) below.

          (c) Notwithstanding the existence of an Advance Facility, the
Servicer, on behalf of the Advance Financing Person, and the Servicer's
Assignee, shall be entitled to receive reimbursements of Advances and/or
Servicing Advances in accordance with Section 3.05 hereof, which entitlement may
be terminated by the Advance Financing Person pursuant to a written notice to
the Trustee in the manner set forth in Section 11.05 hereof. Upon receipt of
such written notice, the Servicer shall no longer be entitled to receive
reimbursement for any Advance Reimbursement Amounts and the Servicer's Assignee
shall immediately have the right to receive from the Collection Account all
Advance Reimbursement Amounts. Notwithstanding the foregoing, and for the
avoidance of doubt, (i) the Servicer and/or the Servicer's Assignee shall only
be entitled to reimbursement of Advance Reimbursement Amounts hereunder from
withdrawals from the Collection Account pursuant to Section 3.05 of this
Agreement and shall not otherwise be entitled to make withdrawals of, or
receive, Advance Reimbursement Amounts that shall be deposited in the
Distribution Account pursuant to Section 3.04(b) hereof, and (ii) none of the
Trustee or the Certificateholders shall have any right to, or otherwise be
entitled to, receive any Advance Reimbursement Amounts to which the Servicer or
Servicer's Assignee, as applicable, shall be entitled pursuant to Section 3.05
hereof. Without limiting the foregoing, none of the Trustee or the
Certificateholders shall have any right to set off against Advance Reimbursement
Amounts hereunder. An Advance Facility may be terminated by the joint written
direction of the Servicer and the related Advance Financing Person. Written
notice of such termination shall be delivered to the Trustee in the manner set
forth in Section 11.05 hereof. The Trustee shall have no duty or liability with
respect to the calculation of any Advance Reimbursement Amount and shall be
entitled to rely without independent investigation on the Advance Facility
Notice and on such Servicer's report of the amount of Advance Reimbursement
Amounts and Servicing Advance Reimbursement Amounts that were included in the
remittance from such Servicer to the Trustee pursuant to Section 4.07. Such
Servicer shall maintain and provide to any successor Servicer a detailed
accounting on a loan-by-loan basis as to amounts advanced by, pledged or
assigned to, and reimbursed to any Advance Financing Person. The successor
Servicer shall be entitled to rely on any such information provided by the
predecessor Servicer, and the successor Servicer shall not be liable for any
errors in such information.

          (d) [Reserved.]

          (e) As between a predecessor Servicer and its Advance Financing
Person, on the one hand, and a successor Servicer and its Advance Financing
Person, if any, on the other hand, Advance Reimbursement Amounts on a
loan-by-loan basis with respect to each Mortgage Loan as to which a

                                      100

<PAGE>

Advance and/or Servicing Advance shall have been made and be outstanding shall
be allocated on a "first-in, first out" basis. In the event the Servicer's
Assignee shall have received some or all of an Advance Reimbursement Amount
related to Advances and/or Servicing Advances that were made by a Person other
than such predecessor Servicer or its related Advance Financing Person in error,
then such Servicer's Assignee shall be required to remit any portion of such
Advance Reimbursement Amount to each Person entitled to such portion of such
Advance Reimbursement Amount. Without limiting the generality of the foregoing,
the Servicer shall remain entitled to be reimbursed by the Advance Financing
Person for all Advances and/or Servicing Advances funded by the Servicer to the
extent the related Advance Reimbursement Amounts have not been assigned or
pledged to such Advance Financing Person or Servicer's Assignee.

          (f) For purposes of any certification of a Servicing Officer of the
Servicer made pursuant to Section 4.07(d), any Nonrecoverable Advance referred
to therein may have been made by such Servicer or any predecessor Servicer. In
making its determination that any Advance or Servicing Advance theretofore made
has become a Nonrecoverable Advance, the Servicer shall apply the same criteria
in making such determination regardless of whether such Advance or Servicing
Advance shall have been made by the Servicer or any predecessor Servicer.

          (g) The Trustee shall not, as a result of the existence of any Advance
Facility, have any additional responsibility to track or monitor Advance
Reimbursement Amounts or any Advance Facility, and, except as expressly provided
in Section 3.30(c) above, is not and shall not be obligated to make any payment
with respect to any Advance Reimbursement Amount. The Servicer hereby
indemnifies the Trustee, the Trust Fund and any successor Servicer, as
applicable, from and against any claims, losses, liabilities or damages
resulting from any claim by the related Advancing Person, except to the extent
that such claim, loss, liability or damage resulted from or arose out of
negligence, recklessness or willful misconduct on the part of the Trustee or the
successor Servicer, or failure by the successor Servicer or the Trustee to remit
funds as required by this Agreement or the commission of an act or omission to
act by the successor Servicer or the Trustee, and the passage of any applicable
cure or grace period, such that a Servicer Event of Termination under this
Agreement occurs or such entity is subject to termination for cause under this

Trust"), the corpus of which shall be held by the Supplemental Interest Trust
Trustee for the benefit of the holders of the Class A, Class M and Class B
Certificates as a segregated subtrust of the Trust Fund. The Supplemental
Interest Trust shall be a party to the Swap Agreement and shall contain the Swap
Account, which shall each be an Eligible Account, and funds deposited therein
shall be held separate and apart from, and shall not be commingled with, any
other moneys, including, without limitation, other moneys of the Trustee held
pursuant to this Agreement. In no event shall any funds deposited in the Swap
Account be credited to or made available to any other account of the Trust Fund.
The records of the Trustee shall at all times reflect that the Supplemental
Interest Trust is a subtrust of the Trust Fund, the assets of which are
segregated from other assets of the Trust Fund.

     The Trustee shall enforce all of the rights of the Supplemental Interest
Trust and exercise any remedies under the Swap Agreement. In the event the Swap
Agreement is terminated as a result of the designation by either party thereto
of an Early Termination Date (as defined in the Swap Agreement), the Depositor
shall find a replacement counterparty to enter into a replacement swap agreement
utilizing the amounts of the net Swap Termination Payments received.

     For each Distribution Date, through and including the Distribution Date in
June 2011, the Trustee shall, based on the Significance Estimate (which shall be
provided to the Trustee by the Depositor within five Business Days prior to the
Distribution Date), calculate the Significance Percentage of the Swap Agreement.
If on any such Distribution Date, the Significance Percentage is equal to or
greater than 9%, the Trustee shall promptly notify the Depositor and the
Depositor, on behalf of the Trustee, shall obtain the financial information
required to be delivered by the Swap Counterparty pursuant to the terms of the
Swap Agreement. If, on any succeeding Distribution Date through and including
the Distribution Date in June 2011, the Significance Percentage is equal to or
greater than 10%, the Trustee shall promptly notify the Depositor and the
Depositor shall, within five Business Days of such Distribution Date, deliver to
the Trustee the financial information provided to it by the Swap Counterparty
for inclusion in the Form 10-D relating to such Distribution Date.

     Any Swap Termination Payment received by the Supplemental Interest Trust
Trustee shall be deposited in the Swap Account and shall be used to make any
upfront payment required under a replacement swap agreement and any upfront
payment received from the counterparty to a replacement swap agreement shall be
used to pay any Swap Termination Payment owed to the Swap Counterparty.

     Notwithstanding anything contained herein, in the event that a replacement
swap agreement cannot be obtained within 30 days after receipt by the
Supplemental Interest Trust Trustee of the Swap Termination Payment paid by the
terminated Swap Counterparty, the Supplemental Interest Trust Trustee shall
deposit such Swap Termination Payment into a separate, segregated non-interest
bearing subtrust established by the Trustee and the Trustee shall, on each
Distribution Date following receipt of such Swap Termination Payment, withdraw
from such subtrust, an amount equal to the Net Swap Payment, if any, that would
have been paid to the Supplemental Interest Trust by the original Swap
Counterparty (computed in accordance with the original Swap Agreement) and
distribute such amount in accordance with this Section 4.02(i). Any such
subtrust shall not be an asset of any REMIC. Any amounts remaining in such
subtrust shall be distributed to the holders of the Class CE-1 Certificates on
the Distribution Date following the earlier of (i) the termination of the Trust
Fund pursuant to Section 10.01 and (ii) the Distribution Date in June 2011.

     On any Distribution Date, any Swap Termination Payments or Net Swap
Payments owed to the Swap Counterparty will be paid out of, or any Net Swap
Payments or Swap Termination Payments received from the Swap Counterparty will
be deposited into, the Swap Account. The Supplemental

                                      110

<PAGE>

Interest Trust will not be an asset of any REMIC. Funds in the Swap Account
within the Supplemental Interest Trust shall be distributed in the following
order of priority by the Trustee:

               (i) to the Swap Counterparty, from the Swap Account only, all Net
Swap Payments, if any, owed to the Swap Counterparty for such Distribution Date;

               (ii) to the Swap Counterparty, from the Swap Account only, any
Swap Termination Payment, other than a Defaulted Swap Termination Payment, if
any, owed to the Swap Counterparty;

               (iii) to each class of the Class A-1 Certificates, on a pro rata
basis, any Accrued Certificate Interest with respect to such class to the extent
unpaid pursuant to Section 4.01 and Section 4.02(b);

               (iv) to each class of the Class A-1 Certificates, on a pro rata
basis, any Interest Carry Forward Amount with respect to such class to the

               (v) sequentially, to the Class M-1 Certificates, the Class M-2
Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the Class
M-5 Certificates, the Class M-6 Certificates, the Class B-1 Certificates, the
Class B-2 Certificates and the Class B-3 Certificates, in that order, any

Class B-2 Certificates and the Class B-3 Certificates, in that order, any
Interest Carry Forward with respect to such class to the extent unpaid pursuant
to Section 4.01 and Section 4.02(b);

               (vii) to the P&I Certificates, to pay principal as described and
in the same manner and order of priority as set forth in Section 4.02(a) in
order to maintain the Targeted Overcollateralization Amount, and after giving
effect to distributions from Principal Distribution Amount for each such Class;

               (viii) sequentially, to each Class of the Class M-1, Class M-2,
Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2 and Class B-3
Certificates, in that order, any remaining Unpaid Realized Loss Amount for such
Distribution Date;

               (ix) to the Class A-1 Certificates, on a pro rata basis, any Net
WAC Carryover Amount to the extent not paid pursuant to Section 4.02(b);

               (x) sequentially, to the Class M-1 Certificates, the Class M-2
Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the Class
M-5 Certificates, the Class M-6 Certificates, the Class B-1 Certificates, the
Class B-2 Certificates and the Class B-3 Certificates, in that order, any Net

               (xi) to the Swap Counterparty, from the Swap Account only, any
Defaulted Swap Termination Payment owed to the Swap Counterparty to the extent
not already paid; and

               (xii) to the Class CE-1 Certificates any remaining amount.

                                      111
<PAGE>

     Notwithstanding the foregoing, however, the sum of all cumulative amounts
distributed pursuant to clauses (vii) and (viii) above shall not exceed the
cumulative Realized Losses incurred. Upon termination of the Trust Fund, any
amounts remaining in the Swap Account within the Supplemental Interest Trust
shall be distributed pursuant to the priorities set forth in this Section
4.02(i).

     With respect to the failure of the Swap Counterparty to perform any of its
obligations under the Swap Agreement, the breach by the Swap Counterparty of any
of its representations and warranties made pursuant to the Swap Agreement, or
the termination of the Swap Agreement, the Trustee shall send any notices and
make any demands required hereunder.

     Section 4.03 Allocation of Losses.

     Realized Losses shall be allocated first against any Initial
Overcollateralization Amount remaining and second to the Subsequent
Overcollateralization Amount, until the Overcollateralization Amount has been
reduced to zero. If, after giving effect to the distribution of the Principal
Distribution Amount on any Distribution Date the aggregate Certificate Principal
Balance of the Class A, Class M and Class B Certificates exceeds the Pool
Balance as of the end of the related Collection Period, such excess will be
allocated against the Class B-5, Class B-4, Class B-3, Class B-2, Class B-1,
Class M-6, Class M-5, Class M-4, Class M-3, Class M-2 and Class M-1
Certificates, in that order, until the respective Certificate Principal Balances
thereof are reduced to zero.

     Special Hazard Losses will be allocated as described above, provided that
if the cumulative amount of such losses, as of any date of determination,
exceeds the greatest of (i) 1.0% of the Pool Balance as of the Cut-off Date,
(ii) two times the amount of the principal balance of the largest Mortgage Loan
as of the date of determination and (iii) an amount equal to the aggregate
principal balances of the Mortgage Loans in the largest zip-code concentration
in the State of California as of the date of determination, such losses will be
allocated among the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class
M-6, Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Certificates, pro
rata, based on their respective Certificate Principal Balances. For the
avoidance of doubt, any losses allocated as Special Hazard Losses shall not be
reimbursed pursuant to Section 4.02(b) as Realized Loss Amortization Amounts.

     Section 4.04 Method of Distribution.

     The Trustee shall make distributions in respect of a Distribution Date to
each Certificateholder of record on the related Record Date (other than as
provided in Section 10.01 respecting the final distribution) by wire transfer in
immediately available funds to the account of the Person entitled thereto or, if
such Person shall have so notified the Trustee in writing at least five Business
Days prior to the Record Date immediately prior to such Distribution Date and is
the registered owner of such Certificates ,by check mailed by first class mail
to the address of the Person entitled thereto, as such name and address shall
appear on the Certificate Register, provided that the Trustee may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Distributions among Certificateholders shall be made in proportion to the
Percentage Interests evidenced by the Certificates held by such
Certificateholders.

     Section 4.05 Distributions on Book-Entry Certificates.

     Each distribution with respect to a Book-Entry Certificate shall be paid to
the Depository, which shall credit the amount of such distribution to the
accounts of its Depository Participants in accordance with its normal
procedures. Each Depository Participant shall be responsible for disbursing such
distribution to the Certificate Owners that it represents and to each indirect
participating brokerage firm (a

                                       112

"brokerage firm" or "indirect participating firm") for which it acts as agent.
Each brokerage firm shall be responsible for disbursing funds to the Certificate
Owners that it represents. All such credits and disbursements with respect to a
Book-Entry Certificate are to be made by the Depository and the Depository
Participants in accordance with the provisions of the Certificates. None of the

therefor except as otherwise provided by applicable law.

     The Trustee may fully rely upon and shall have no liability with respect to
information with respect to the Mortgage Loans provided by the Servicer.

     In the case of information furnished pursuant to subclauses (i), (iii) and
(iv) above, the amounts shall be expressed in a separate section of the report

     The Trustee's responsibility for providing the above statement is limited
to the availability, timeliness and accuracy of the information derived from the
Servicer (or as provided by such other party providing notice of a material
breach in clauses (xxii) and (xxiii) above.

          (b) Within a reasonable period of time after the end of each calendar

to such Person a statement containing the information set forth in subclauses

Such obligation of the Trustee shall be deemed to have been satisfied to the
extent that substantially comparable information shall be prepared and furnished
by the Trustee to Certificateholders pursuant to any requirements of the Code as
are in force from time to time.

          (c) On each Distribution Date, the Trustee shall make available to the

     Section 4.07 Remittance Reports; Advances.

          (a) On the second Business Day following each Determination Date but
in no event less than four Business Days prior to the related Distribution Date,
the Servicer shall deliver to the Trustee by telecopy (or by such other means as
the Servicer and the Trustee may agree from time to time) a Remittance Report
with respect to the related Distribution Date. On the same date, the Servicer
shall forward to the Trustee by overnight mail a computer readable magnetic tape
or diskette or in such other medium as may be agreed between the Servicer and
the Trustee containing the information set forth in such Remittance Report, such
other information reasonably available to it with respect to the Mortgage Loans
as the Trustee may reasonably request or order in order for the Trustee to
perform the calculations necessary to make the distributions contemplated by
Section 4.01, 4.02 and 4.03 and to prepare the statements to Certificateholders
contemplated by Section 4.06 with respect to the related Distribution Date. The
Trustee shall not be responsible to recompute, recalculate or verify any
information provided to it by the Servicer.

          (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.07(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Collection Period in respect of the Mortgage Loans, which
Monthly Payments were delinquent on a contractual basis as of the close of
business on the related Determination Date and (ii) with respect to each REO
Property, which REO Property was acquired during or prior to the related
Prepayment Period and as to which such REO Property an REO Disposition did not
occur during the related Prepayment Period, an amount equal to the excess, if
any, of the interest portion of Monthly Payments (net of the related Servicing
Fee) that would have been due on the related Due Date

                                       115

<PAGE>

in respect of the related Mortgage Loans, over the net income from such REO
Property deposited in the Collection Account pursuant to Section 3.13 for
distribution on such Distribution Date. For purposes of the preceding sentence,
the Monthly Payment on each Balloon Mortgage Loan with a delinquent Balloon
Payment is equal to the assumed monthly payment that would have been due on the
related Due Date based on the original principal amortization schedule for such
Balloon Mortgage Loan. The Servicer shall not be required to make any Advances
with respect to the principal portion of the Monthly Payments that would have
been due on the related Due Date with respect to Second Lien Mortgage Loans and
shall not make any Advances with respect to the principal portion of the Monthly
Payments that would have been due on the related Due Date with respect to REO
Properties. The Servicer will not advance shortfalls in interest collections due
to bankruptcy proceedings or the application of the Relief Act.

     On or before 3:00 PM New York time on the Servicer Remittance Date, the
Servicer shall remit in immediately available funds to the Trustee for deposit
in the Distribution Account an amount equal to the aggregate amount of Advances,
if any, to be made in respect of the Mortgage Loans and REO Properties for the
related Distribution Date either (i) from its own funds or (ii) from the
Collection Account, to the extent of funds held therein for future distribution
(in which case it will cause to be made an appropriate entry in the records of
the Collection Account that amounts held for future distribution have been, as
permitted by this Section 4.07, used by the Servicer in discharge of any such
Advance or Servicing Advance) or (iii) in the form of any combination of (i) and
(ii) aggregating the total amount of Advances to be made by the Servicer with
respect to the Mortgage Loans and REO Properties. In addition, the Servicer
shall have the right to reimburse itself for any such Advance from amounts held
from time to time in the Collection Account to the extent such amounts are not
then required to be distributed. Any amounts held for future distribution and so
used shall be appropriately reflected in the Servicer's records and replaced by
the Servicer by deposit in the Collection Account on or before any future
Servicer Remittance Date to the extent that the Available Funds for the related
Distribution Date (determined without regard to Advances to be made on the
Servicer Remittance Date) shall be less than the total amount that would be
distributed to the Classes of Certificateholders pursuant to Section 4.01 and
4.02 on such Distribution Date if such amounts held for future distributions had
not been so used to make Advances. The Servicer may reimburse itself from any
amounts in the Collection Account for any prior Advances or Servicing Advances
that have not been reimbursed at the time the Mortgage Loan is modified. The
Trustee will provide notice to the Servicer by telecopy by the close of business
on any Servicer Remittance Date in the event that the amount remitted by the
Servicer to the Trustee on such date is less than the Advances required to be
made by the Servicer for the related Distribution Date, as set forth in the
related Remittance Report.

          (c) The obligation of the Servicer to make such Advances is mandatory,
notwithstanding any other provision of this Agreement but subject to (d) below,
and, with respect to any Mortgage Loan or REO Property, shall continue until the
earlier of such time as the Trust acquires title to the related Mortgaged
Property or such Mortgage Loan is paid in full by the Mortgagor or disposed of
by the Trust, or until the recovery of all Liquidation Proceeds thereon.

          (d) Notwithstanding anything herein to the contrary, no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer if such
Advance would, if made, constitute a Nonrecoverable Advance. The determination
by the Servicer that it has made a Nonrecoverable Advance or that any proposed
Advance, if made, would constitute a Nonrecoverable Advance, shall be evidenced
by an Officers' Certificate of the Servicer delivered to the Depositor and the
Trustee.

                                THE CERTIFICATES

     Section 5.01 The Certificates.

     Each of the Class A, Class M, Class B, Class P, Class CE-1, Class CE-2,
Class R and Class R-X Certificates shall be substantially in the forms annexed
hereto as exhibits, and shall, on original issue, be executed by the Trustee and
authenticated and delivered by the Certificate Registrar to or upon the receipt
of a Written Order to Authenticate from the Depositor concurrently with the sale
and assignment to the Trustee of the Trust Fund. Each Class of the Class A,
Class M and Class B Certificates shall be initially evidenced by one or more
Certificates representing a Percentage Interest with a minimum dollar (or
notional amount) denomination of $25,000 and integral multiples of $1 in excess
thereof. The Class P, Class CE-1, Class CE-2 and Class R Certificates are
issuable only in minimum Percentage Interests of 10%. The Class R-X Certificates
are issuable only in minimum Percentage Interests of 50%.

     The Certificates shall be executed on behalf of the Trust by manual or
facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Certificate Registrar substantially in the form
provided for herein, and such authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Class A, Class M and
Class B Certificates shall be Book-Entry Certificates. The Class P, Class CE-1,
Class CE-2, Class R and Class R-X Certificates shall not be Book-Entry
Certificates but shall be issued in fully registered certificate form.

     The Class B-5 Certificates sold in offshore transactions in reliance on
Regulation S shall be issued initially in the form of one or more permanent
global certificates in definitive, fully registered form without interest
coupons with the applicable legends set forth in Exhibit B-3 hereto added to the
forms of such Certificates (each, a "Book-Entry Regulation S Global Security"),
which shall be deposited on behalf of the Holders of such Certificates
represented thereby with the Certificate Registrar, as custodian for DTC and
registered in the name of a nominee of DTC, duly executed and authenticated by
the Certificate Registrar as hereinafter provided. The aggregate principal
amounts of the Book-Entry Regulation S Global Securities may from time to time
be increased or decreased by adjustments made on the records of the Certificate
Registrar or DTC or its nominee, as the case may be, as hereinafter provided.

     Section 5.02 Registration of Transfer and Exchange of Certificates.

          (a) The Certificate Registrar shall cause to be kept at the Corporate
Trust Office of the Trustee 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. The Trustee shall initially serve as
Certificate Registrar for the purpose of registering Certificates and transfers
and exchanges of Certificates as herein provided. The Trustee as Certificate
Registrar shall be subject to the same standards of care, limitations on
liability and rights to indemnity as the Trustee, and the provisions of Sections
8.01, 8.02, 8.03, 8.04, 8.05, 8.14 and 8.15 shall

                                       117

apply to the Certificate Registrar to the same extent as they apply to the
Trustee. Any Certificate Registrar appointed in accordance with this Section
5.02(a) may at any time resign by giving at least 30 days' advance written
notice of resignation to the Trustee, the Servicer and the Depositor, such
resignation to become effective upon appointment of a successor Certificate
Registrar.

     Upon surrender for registration of transfer of any Certificate at any
office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of a Residual Certificate,
upon satisfaction of the conditions set forth below, the Trustee on behalf of
the Trust shall execute and the Certificate Registrar shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Certificates of the same aggregate Percentage Interest.

     At the option of the Certificateholders, Certificates may be exchanged for
other Certificates in authorized denominations and the same aggregate Percentage
Interests, upon surrender of the Certificates to be exchanged at any such office
or agency. Whenever any Certificates are so surrendered for exchange, the
Trustee shall execute on behalf of the Trust and the Certificate Registrar shall
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of transfer or exchange shall (if so required by the Trustee or the
Certificate Registrar) be duly endorsed by, or be accompanied by a written
instrument of transfer satisfactory to the Trustee and the Certificate Registrar
duly executed by, the Holder thereof or his attorney duly authorized in writing.

          (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository, the initial Depository, by, or on behalf of, the Depositor; or
to, and deposited with the Certificate Custodian, on behalf of the Depository,
if directed to do so pursuant to instructions from the Depository. Except as
provided in paragraph (c) below, the Book-Entry Certificates shall at all times
remain registered in the name of the Depository or its nominee and at all times:
(i) registration of such Certificates may not be transferred by the Trustee
except to another Depository; (ii) the Depository shall maintain book-entry
records with respect to the Certificate Owners and with respect to ownership and
transfers of such Certificates; (iii) ownership and transfers of registration of
such Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iv) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (v)
the Trustee shall for all purposes deal with the Depository as representative of
the Certificate Owners of the Certificates for purposes of exercising the rights
of Holders 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; (vi) the Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners; and (vii) the direct participants of the Depository shall have no rights
under this Agreement under or with respect to any of the Certificates held on
their behalf by the Depository, and the Depository may be treated by the Trustee
and their agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

     All transfers by Certificate Owners of Book-Entry 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
that it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. The parties hereto are
hereby authorized to execute a Letter of Representations with the Depository or
take such other action as may be necessary or desirable to register a Book-Entry

                                       118

Certificate to the Depository. In the event of any conflict between the terms of
any such Letter of Representation and this Agreement, the terms of this
Agreement shall control.

          (c) If (i)(x) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and (y) the Depositor is unable to locate a
qualified successor, (ii) the Depositor, at its sole option with the consent of
the Trustee elects to terminate the book-entry system through the Depository or
(iii) after the occurrence of a Servicer Event of Termination, the Certificate
Owners of each Class of Book-Entry Certificates representing Percentage
Interests of such Classes aggregating not less than 51% advises the Trustee and
Depository through the Financial Intermediaries and the Depository Participants
in writing that the continuation of a book-entry system through the Depository
to the exclusion of definitive, fully registered certificates (the "Definitive
Certificates") to Certificate Owners is no longer in the best interests of the
Certificate Owners. Upon surrender to the Certificate Registrar of the
Book-Entry Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall, at the
Depositor's expense, in the case of (ii) above, or the Seller's expense, in the
case of (i) and (iii) above, execute on behalf of the Trust and the Certificate
Registrar shall authenticate the Definitive Certificates. Neither the Depositor
nor the Trustee shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Certificates, the Trustee, the
Certificate Registrar, the Servicer, any Paying Agent and the Depositor shall
recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

          (d) No transfer, sale, pledge or other disposition of any Private
Certificate shall be made unless such disposition is exempt from the
registration requirements of the Securities Act of 1933, as amended (the "1933
Act"), and any applicable state securities laws or is made in accordance with
the 1933 Act and laws. In the event of any such transfer, other than the initial
transfer of the Private Certificates by the Depositor, (i) unless such transfer
is made in reliance upon Rule 144A (as evidenced by the investment letter
delivered to the Certificate Registrar, in substantially the form attached
hereto as Exhibit J) under the 1933 Act, the Certificate Registrar and the
Depositor may require a written Opinion of Counsel (which may be in-house
counsel) acceptable to and in form and substance reasonably satisfactory to the
Certificate Registrar and the Depositor that such transfer may be made pursuant
to an exemption, describing the applicable exemption and the basis therefor,
from the 1933 Act or is being made pursuant to the 1933 Act, which Opinion of
Counsel shall not be an expense of the Certificate Registrar, the Trustee or the
Depositor or (ii) the Certificate Registrar shall require the transferor to
execute a transferor certificate (in substantially the form attached hereto as
Exhibit L) and the transferee to execute an investment letter (in substantially
the form attached hereto as Exhibit J) acceptable to and in form and substance
reasonably satisfactory to the Depositor and the Certificate Registrar
certifying to the Depositor and the Certificate Registrar the facts surrounding
such transfer, which investment letter shall not be an expense of the
Certificate Registrar or the Depositor. The Holder of a Private Certificate
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Certificate Registrar and the Depositor against any liability that
may result if the transfer is not so exempt or is not made in accordance with
such federal and state laws.

     By acceptance of a Regulation S Global Security, whether upon original
issuance or subsequent transfer, each Holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth thereon and
agrees that it will only transfer such a Certificate as provided herein. In
addition, each Holder of a Regulation S Global Security shall be deemed to have
represented and warranted to the Trustee, the Depositor, the Certificate
Registrar and any of their respective successors that: (i) such Person is not a
"U.S. person" within the meaning of Regulation S and was, at the time the buy
order was originated, outside the United States and (ii) such Person understands
that such Certificates have not been

                                       119

<PAGE>

registered under the Securities Act and that (x) until the expiration of the
40-day distribution compliance period (within the meaning of Regulation S), no
offer, sale, pledge or other transfer of such Certificates or any interest
therein shall be made in the United States or to or for the account or benefit
of a U.S. person (each as defined in Regulation S), (y) if in the future it
decides to offer, resell, pledge or otherwise transfer such Certificates, such
Certificates may be offered, resold, pledged or otherwise transferred only (A)
to a person which the seller reasonably believes is a "qualified institutional
buyer" (a "QIB") as defined in Rule 144A under the Securities Act, that is
purchasing such Certificates for its own account or for the account of a
qualified institutional buyer to which notice is given that the transfer is
being made in reliance on Rule 144A or (B) in an offshore transaction (as
defined in Regulation S) in compliance with the provisions of Regulation S, in
each case in compliance with the requirements of this Agreement; and it will
notify such transferee of the transfer restrictions specified in this Section.

     The beneficial ownership (as determined for federal income tax purposes) of
a Class P or Class CE-1 Certificate shall not be transferred to a non-United
States Person unless the Certificate Registrar has received, in the manner
required by applicable Treasury regulations (and with all required attachments,
including, where the non-United States Person is providing a Form W-8IMY, Forms
W-8BEN, W-8EXP or W-9 from all persons treated as beneficially owning an
interest in the Class CE-1 or Class P Certificate through such non-U.S. Person
either directly, through an intermediary or through another entity that is
treated as a partnership for U.S. federal income tax purposes), a properly
completed Internal Revenue Service Form W-8IMY, Form W-8BEN, Form W-8EXP or Form
W-8ECI from such non-United States Person. No Class CE-1 Certificate may be
pledged or used as collateral for any obligation if it would cause any portion
of the Trust Fund to be treated as a taxable mortgage pool under Section 7701(i)
of the Code.

     No transfer of a Certificate that is neither an ERISA-Restricted
Certificate nor a Residual Certificate shall be registered unless the Trustee
and the Certificate Registrar shall have received a representation substantially
in the form of Exhibit I hereto that either (i) the transferee is not, and is
not acting for, on behalf of or with any assets of, an employee benefit plan or
other arrangement subject to Title I of ERISA or plan subject to Section 4975 of
the Code, or (ii) until the termination of the Swap Agreement, the acquisition
and holding of such Certificate will not constitute or result in a non-exempt,
prohibited transaction under Title I of ERISA or Section 4975 of the Code.

     No transfer of an ERISA-Restricted Certificate or a Residual Certificate
shall be registered unless the Trustee and the Certificate Registrar shall have
received (I) a representation from the transferee of such Certificate,
acceptable to and in form and substance satisfactory to the Trustee and the
Certificate Registrar (such requirement is satisfied only by the Certificate
Registrar's receipt of a representation letter from the transferee substantially
in the form of Exhibit I or Exhibit K hereto, as applicable), to the effect that
such transferee is not an employee benefit plan or arrangement subject to Title
I of ERISA, a plan subject to Section 4975 of the Code or a plan subject to any
state, local, federal, non-U.S. or other law substantively similar to the
foregoing provisions of ERISA or the Code ("Similar Law") (collectively, a
"Plan"), and is not directly or indirectly acquiring the Certificate for, on
behalf of or with any assets of any such Plan, or (II) solely in the case of an
ERISA-Restricted Certificate, (A) if the Certificate has been the subject of an
ERISA-Qualifying Underwriting, a representation letter from the transferee
substantially in the form of Exhibit I hereto, that the transferee is an
insurance company that is acquiring the Certificate with assets of an "insurance
company general account" as defined in Section V(e) of PTCE 95-60 and the
acquisition and holding of the Certificate are covered and exempt under Sections
I and III of PTCE 95-60, or (B) solely in the case of a Definitive Certificate,
an Opinion of Counsel satisfactory to the Trustee and the Certificate Registrar,
and upon which the Trustee and the Certificate Registrar shall be entitled to
rely, to the effect that the acquisition and holding of such Certificate by the
transferee will not result in a nonexempt prohibited transaction under Title I
of ERISA or Section 4975 of the Code, or a violation of

                                       120

<PAGE>

Similar Law, and will not subject the Certificate Registrar, the Depositor, the
Servicer or the Trustee to any obligation in addition to those undertaken by
such entities in this Agreement, which opinion of counsel shall not be an
expense of the Certificate Registrar, the Depositor, the Servicer or the
Trustee.

     The representations set forth in the preceding two paragraphs (other than
clause (II)(B) in the immediately preceding paragraph) shall be deemed to have
been made to the Certificate Registrar and the Trustee by the Certificate
Owner's acceptance of the beneficial interest in any such class of Certificates,
unless the Trustee and the Certificate Registrar shall have received from the
transferee an alternative representation acceptable in form and substance to the
Trustee and the Certificate Registrar.

     Notwithstanding any other provision herein to the contrary, any purported
transfer of a Certificate to or on behalf of a Plan without the delivery to the
Trustee and the Certificate Registrar of a representation or an Opinion of
Counsel satisfactory to the Trustee and the Certificate Registrar as described
above shall be void and of no effect. None of the Certificate Registrar, the
Depositor, the Servicer or the Trustee shall be under any liability to any
Person for any registration or transfer of any Certificate that is in fact not
permitted by this Section 5.02(d) nor shall the Paying Agent be under any
liability for making any payments due on such Certificate to the holder thereof
or taking any other action with respect to such holder under the provisions of
this Agreement so long as the transfer was registered by the Certificate
Registrar in accordance with the foregoing requirements. The Certificate
Registrar, Depositor, Servicer, Paying Agent and/or Trustee shall be entitled,
but not obligated, to recover from any holder of any Certificate that was in
fact a Plan and that held such Certificate in violation of this Section 5.02(d)
all payments made on such Certificate at and after the time it commenced such
holding. Any such payments so recovered shall be paid and delivered to the last
preceding holder of such Certificate that is not a Plan.

     Each Person who has or who acquires any Ownership Interest in a Residual
Certificate shall be deemed by the acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the following provisions and to have
irrevocably appointed the Depositor or its designee as its attorney-in-fact to
negotiate the terms of any mandatory sale under clause (v) below and to execute
all instruments of transfer and to do all other things necessary in connection
with any such sale, and the rights of each Person acquiring any Ownership
Interest in a Residual Certificate are expressly subject to the following
provisions:

               (i) Each Person holding or acquiring any Ownership Interest in a
Residual Certificate shall be a Permitted Transferee and shall promptly notify
the Certificate Registrar of any change or impending change in its status as a
Permitted Transferee.

               (ii) No Person shall acquire an Ownership Interest in a Residual
Certificate unless such Ownership Interest is a pro rata undivided interest.

               (iii) In connection with any proposed transfer of any Ownership
Interest in a Residual Certificate, the Certificate Registrar shall as a
condition to registration of the transfer, require delivery to it, in form and
substance satisfactory to it, of each of the following:

                    (A) an affidavit in the form of Exhibit K hereto from the
proposed transferee to the effect that, among other things, such transferee is a
Permitted Transferee and that it is not acquiring its Ownership Interest in the
Residual Certificate that is the subject of the proposed transfer as a nominee,
trustee or agent for any Person who is not a Permitted Transferee; and

                                       121

<PAGE>

                    (B) a covenant of the proposed transferee to the effect that
the proposed transferee agrees to be bound by and to abide by the transfer
restrictions applicable to the Residual Certificates.

               (iv) Any attempted or purported transfer of any Ownership
Interest in a Residual Certificate in violation of the provisions of this
Section shall be absolutely null and void and shall vest no rights in the
purported transferee. If any purported transferee shall, in violation of the
provisions of this Section, become a Holder of a Residual Certificate, then the
prior Holder of such Residual Certificate that is a Permitted Transferee shall,
upon discovery that the registration of transfer of such Residual Certificate
was not in fact permitted by this Section, be restored to all rights as Holder
thereof retroactive to the date of registration of transfer of such Residual
Certificate. The Certificate Registrar shall be under no liability to any Person
for any registration of transfer of a Residual Certificate that is in fact not
permitted by this Section or for making any distributions due on such Residual
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement so long as the Certificate
Registrar received the documents specified in clause (iii). The Trustee shall be
entitled to recover from any Holder of a Residual Certificate that was in fact
not a Permitted Transferee at the time such distributions were made all
distributions made on such Residual Certificate. Any such distributions so
recovered by the Trustee shall be distributed and delivered by the Trustee to
the prior Holder of such Residual Certificate that is a Permitted Transferee.

               (v) If any Person other than a Permitted Transferee acquires any
Ownership Interest in a Residual Certificate in violation of the restrictions in
this Section, then the Certificate Registrar shall have the right but not the
obligation, without notice to the Holder of such Residual Certificate or any
other Person having an Ownership Interest therein, to notify the Depositor to
arrange for the sale of such Residual Certificate. The proceeds of such sale,
net of commissions (which may include commissions payable to the Depositor or
its affiliates in connection with such sale), expenses and taxes due, if any,
will be remitted by the Trustee to the previous Holder of such Residual
Certificate that is a Permitted Transferee, except that in the event that the
Trustee determines that the Holder of such Residual Certificate may be liable
for any amount due under this Section or any other provisions of this Agreement,
the Trustee may withhold a corresponding amount from such remittance as security
for such claim. The terms and conditions of any sale under this clause (v) shall
be determined in the sole discretion of the Trustee and it shall not be liable
to any Person having an Ownership Interest in a Residual Certificate as a result
of its exercise of such discretion.

               (vi) If any Person other than a Permitted Transferee acquires any
Ownership Interest in a Residual Certificate in violation of the restrictions in
this Section, then the Trustee will provide to the Internal Revenue Service, and
to the persons specified in Sections 860E(e)(3) and (6) of the Code, information
needed to compute the tax imposed under Section 860E(e)(5) of the Code on
transfers of residual interests to disqualified organizations. The Trustee shall
be entitled to reasonable compensation for providing such information from the
person to whom it is provided.

The foregoing provisions of this Section shall cease to apply to transfers
occurring on or after the date on which there shall have been delivered to the
Certificate Registrar, in form and substance satisfactory to the Certificate
Registrar, (i) written notification from each Rating Agency that the removal of
the restrictions on Transfer set forth in this Section will not cause such
Rating Agency to downgrade its rating of the Certificates and (ii) an Opinion of
Counsel to the effect that such removal will not cause any REMIC hereunder to
fail to qualify as a REMIC.

          (e) No service charge shall be made for any registration of transfer
or exchange of Certificates of any Class, but the Certificate Registrar may
require payment of a sum sufficient to cover

                                       122

<PAGE>

any tax or governmental charge that may be imposed in connection with any
transfer or exchange of Certificates.

     All Certificates surrendered for registration of transfer or exchange shall
be cancelled by the Certificate Registrar and disposed of pursuant to its
standard procedures.

     Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

     If (i) any mutilated Certificate is surrendered to the Certificate
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 Trustee, the Depositor and the Certificate Registrar such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Trustee or the Certificate Registrar that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute on behalf of the Trust, and the Certificate Registrar shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like tenor and Percentage Interest.
Upon the issuance of any new Certificate under this Section, the Trustee or 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 Trustee and the
Certificate Registrar) in connection therewith. Any duplicate Certificate issued
pursuant to this Section, shall constitute complete and indefeasible evidence of
ownership in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

     Section 5.04 Persons Deemed Owners.

     The Servicer, the Depositor, the Trustee, the Certificate Registrar, any
Paying Agent and any agent of the Servicer, the Depositor, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.01
and 4.02 and for all other purposes whatsoever, and none of the Servicer, the
Trust, the Trustee, any Paying Agent nor any agent of any of them shall be
affected by notice to the contrary.

     Section 5.05 Appointment of Paying Agent.

     The Paying Agent shall make distributions to Certificateholders from the
Distribution Account pursuant to Section 4.01 and 4.02 and shall report the
amounts of such distributions to the Trustee. The duties of the Paying Agent may
include the obligation (i) to withdraw funds from the Collection Account
pursuant to Section 3.05 and for the purpose of making the distributions
referred to above and (ii) to distribute statements and provide information to
Certificateholders as required hereunder. The Paying Agent hereunder shall at
all times be an entity duly incorporated and validly existing under the laws of
the United States of America or any state thereof, authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by
federal or state authorities. The Paying Agent shall initially be the Trustee.
The Trustee may appoint a successor to act as Paying Agent, which appointment
shall be reasonably satisfactory to the Depositor and the Rating Agencies. The
Trustee as Paying Agent shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14 and 8.15 shall apply
to the Paying Agent to the same extent as they apply to the Trustee. Any Paying
Agent appointed in accordance with this Section 5.05 may at any time resign by
giving at least 30 days' advance written notice of resignation to the Trustee,
the Servicer and the Depositor, such resignation to become effective upon
appointment of a successor Paying Agent.

     Section 6.01 Liability of the Seller, the Servicer and the Depositor.

     The Seller and the Servicer shall be liable in accordance herewith only to
the extent of the obligations specifically imposed upon and undertaken by the
Seller or Servicer, as the case may be, herein. The Depositor shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
upon and undertaken by the Depositor.

     Section 6.02 Merger or Consolidation of, or Assumption of the Obligations
of, the Seller, the Servicer or the Depositor.

     Any entity into which the Seller, the Servicer or the Depositor may be
merged or consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Seller, the Servicer or the Depositor shall be a
party, or any corporation succeeding to the business of the Seller, the Servicer
or the Depositor, shall be the successor of the Seller, the Servicer or the
Depositor, as the case may be, 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; provided, however, that the successor
Servicer shall satisfy all the requirements of Section 7.02 with respect to the
qualifications of a successor Servicer.

     Section 6.03 Limitation on Liability of the Servicer and Others.

     Neither the Servicer nor any of the directors or officers or employees or
agents of the Servicer shall be under any liability to the Trust or the
Certificateholders for any action taken or for refraining from the taking of any
action by the Servicer in good faith pursuant to this Agreement, or for errors
in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of its willful misfeasance, bad faith or gross negligence in
the performance of duties of the Servicer or by reason of its reckless disregard
of its obligations and duties of the Servicer hereunder; provided, further, that
this provision shall not be construed to entitle the Servicer to indemnity in
the event that amounts advanced by the Servicer to retire any senior lien exceed
Liquidation Proceeds (in excess of related liquidation expenses) realized with
respect to the related Mortgage Loan. The Servicer and any director or officer
or employee or agent of the 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. The Servicer and any director or officer or
employee or agent of the Servicer shall be indemnified by the Trust and held
harmless against any loss, liability or expense incurred in connection with any
legal action relating to this Agreement or the Certificates, other than any
loss, liability or expense incurred by reason of its willful misfeasance, bad
faith or negligence in the performance of duties hereunder or by reason of its
reckless disregard of obligations and duties hereunder. The Servicer may
undertake any such action which it may deem necessary or desirable in respect of
this Agreement, and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the reasonable
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust and the Servicer shall be
entitled to pay such expenses from the proceeds of the Trust or to be reimbursed
therefor pursuant to Section 3.05 upon presentation to the Trustee of
documentation of such expenses, costs and liabilities. The Servicer's right to
indemnity or reimbursement pursuant to this Section shall survive any
resignation or termination of the Servicer pursuant to Section 6.04 or 7.01 with
respect to any losses, expenses, costs or liabilities arising prior to such
resignation or termination (or arising from events

                                       124

<PAGE>

that occurred prior to such resignation or termination). This paragraph shall
apply to the Servicer solely in its capacity as Servicer hereunder and in no
other capacities.

     Section 6.04 Servicer Not to Resign.

     Subject to the provisions of Section 7.01 and Section 6.02, the Servicer
shall not resign from the obligations and duties hereby imposed on it except (i)
upon determination that the performance of its obligations or duties hereunder
are no longer permissible under applicable law or are in material conflict by
reason of applicable law with any other activities carried on by it or its
subsidiaries or Affiliates, the other activities of the Servicer so causing such
a conflict being of a type and nature carried on by the Servicer or its
subsidiaries or Affiliates at the date of this Agreement or (ii) upon
satisfaction of the following conditions: (a) either (x) the Servicer has
proposed a successor servicer to the Trustee in writing and such proposed
successor servicer is reasonably acceptable to the Trustee or (y) the Servicing
Rights Pledgee has delivered to the Trustee a letter signed by the Servicer
whereunder the Servicer resigns as Servicer under this Agreement pursuant to the
second paragraph of this Section 6.04 or the second paragraph of Section
7.02(a); and (b) each Rating Agency shall have delivered a letter to the Trustee
prior to the appointment of the successor servicer stating that the proposed
appointment of such successor servicer as Servicer hereunder will not result in
the reduction or withdrawal of the then current rating of the Regular
Certificates; or the ratings that are in effect; provided, however, that no such
resignation by the Servicer shall become effective until such successor servicer
or, in the case of (i) above, the Trustee shall have assumed the Servicer's
responsibilities and obligations hereunder or the Trustee shall have designated
a successor servicer in accordance with the second paragraph of this Section
6.04 or with Section 7.02. Any such resignation shall not relieve the Servicer
of responsibility for any of the obligations specified in Sections 7.01 and 7.02
as obligations that survive the resignation or termination of the Servicer. Any
such determination permitting the resignation of the Servicer pursuant to clause
(i) above shall be evidenced by an Opinion of Counsel to such effect delivered
to the Trustee. Any such determination permitting the resignation of the
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to
the Trustee.

     The Trustee and the Depositor hereby specifically (i) consent to the pledge
and assignment by the Servicer of all the Servicer's right, title and interest
in, to and under this Agreement to the Servicing Rights Pledgee, for the benefit
of certain lenders, and (ii) provided that no Servicer Event of Termination
exists, agree that upon delivery to the Trustee by the Servicing Rights Pledgee
of a letter signed by the Servicer whereunder the Servicer shall resign as
Servicer under this Agreement, the Trustee shall appoint the Servicing Rights
Pledgee or its designee as successor Servicer, provided that at the time of such
appointment, the Servicing Rights Pledgee or such designee meets the
requirements of a successor Servicer pursuant to Section 7.02(a) and agrees to
be subject to the terms of this Agreement. If, pursuant to any provision hereof,
the duties of the Servicer are transferred to a successor, the entire amount of
the Servicing Fee and other compensation payable to the Servicer pursuant hereto
shall thereafter be payable to such successor.

     Section 6.05 Delegation of Duties.

     In the ordinary course of business, the Servicer at any time may delegate
any of its duties hereunder to any Person, including any of its Affiliates, who
agrees to conduct such duties in accordance with standards comparable to those
set forth in Section 3.01. Such delegation shall not relieve the Servicer of its
liabilities and responsibilities with respect to such duties and shall not
constitute a resignation within the meaning of Section 6.04. At any time that
reporting under the Exchange Act is required, the Servicer shall provide the
Trustee and the Rating Agencies with 30 days prior written notice

                                       125

<PAGE>

prior to the delegation of any of its duties to any Person other than any of the
Servicer's Affiliates or their respective successors and assigns.

          (a) If any one of the following events (each, a "Servicer Event of
Termination") shall occur and be continuing:

               (i) (A) The failure by the Servicer to make any required Advance;
or (B) any other failure by the Servicer to deposit in the Collection Account or
Distribution Account any deposit required to be made under the terms of this
Agreement which continues unremedied for a period of one Business Day after the
date upon which written notice of such failure shall have been given to the
Servicer by the Trustee or by any Holder of a Regular Certificate evidencing at
least 25% of the Voting Rights; or

               (ii) The failure by the Servicer to make any required Servicing
Advance which failure continues unremedied for a period of 30 days, or the
failure by the Servicer duly to observe or perform, in any material respect, any
other covenants, obligations or agreements of the Servicer as set forth in this
Agreement, which failure continues unremedied for a period of 30 days, after the
date (A) on which written notice of such failure, requiring the same to be
remedied, shall have been given to the Servicer by the Trustee or by any Holder
of a Regular Certificate evidencing at least 25% of the Voting Rights or (B)
actual knowledge of such failure by a Servicing Officer of the Servicer; or

               (iii) The entry against the Servicer of a decree or order by a
court or agency or supervisory authority having jurisdiction in the premises for
the appointment of a trustee, conservator, receiver or liquidator in any
insolvency, conservatorship, receivership, readjustment of debt, marshalling 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
unstayed and in effect for a period of 60 days; or

               (iv) The Servicer shall voluntarily go into liquidation, consent
to the appointment of a conservator or receiver or liquidator or similar person
in any insolvency, readjustment of debt, marshalling of assets and liabilities
or similar proceedings of or relating to the Servicer or of or relating to all
or substantially all of its property; or a decree or order of a court or agency
or supervisory authority having jurisdiction in the premises for the appointment
of a conservator, receiver, liquidator or similar person in any insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings, or for the winding-up or liquidation of its affairs, shall have
been entered against the Servicer and such decree or order shall have remained
in force undischarged, unbonded or unstayed for a period of 60 days; or the
Servicer shall admit in writing its inability to pay its debts generally as they
become due, file a petition to take advantage of any applicable insolvency or
reorganization statute, make an assignment for the benefit of its creditors or
voluntarily suspend payment of its obligations.

          (b) Then, and in each and every such case, so long as a Servicer Event
of Termination shall not have been remedied within the applicable grace period,
(x) with respect solely to clause (i)(A) above, if such Advance is not made by
11 AM, New York time, on the Business Day immediately following the Servicer
Remittance Date, the Trustee may terminate all of the rights and obligations of
the Servicer under this Agreement and the Trustee, or a successor servicer
appointed in

                                       126

<PAGE>

accordance with Section 7.02, shall immediately make such Advance and assume,
pursuant to Section 7.02, the duties of a successor Servicer and (y) in the case
of (i)(B), (ii), (iii), (iv) and (v) above, the Trustee shall, at the direction
of the Holders of each Class of Regular Certificates evidencing Percentage
Interests aggregating not less than 51%, by notice then given in writing to the
Servicer (and to the Trustee if given by Holders of Certificates), terminate all
of the rights and obligations of the Servicer as servicer under this Agreement.
Any such notice to the Servicer shall also be given to each Rating Agency, the
Depositor and the Seller. On or after the receipt by the Servicer (and by the
Trustee if such notice is given by the Holders) of such written notice, all
authority and power of the Servicer under this Agreement, whether with respect
to the Certificates or the Mortgage Loans or otherwise, shall pass to and be
vested in the Trustee pursuant to and under this Section; and, without
limitation, the Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the 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 of each Mortgage
Loan and Related Documents or otherwise. The Servicer agrees to cooperate with
the Trustee (or the applicable successor Servicer) in effecting the termination
of the responsibilities and rights of the Servicer hereunder, including, without
limitation, the delivery to the successor servicer of all documents and records
requested by it to enable it to assume the Servicer's functions under this
Agreement within ten Business Days subsequent to such notice, the transfer
within one Business Day subsequent to such notice to the Trustee (or the
applicable successor Servicer) for the administration by it of all cash amounts
that shall at the time be held by the Servicer and to be deposited by it in the
Collection Account, the Distribution Account, any REO account or any Escrow
Account or that have been deposited by the Servicer in such accounts or
thereafter received by the Servicer with respect to the Mortgage Loans or any
REO Property received by the Servicer. All reasonable costs and expenses
(including attorneys' fees) incurred in connection with transferring the
servicing to the successor Servicer and amending this Agreement to reflect such
succession as Servicer pursuant to this Section shall be paid by the predecessor
Servicer (or if the predecessor Servicer is the Trustee, the initial Servicer)
upon presentation of reasonable documentation of such costs and expenses or, if
not paid by such predecessor servicer, then by the Trust Fund.

     Section 7.02 Trustee to Act; Appointment of Successor.

          (a) Within 90 days of the time the Servicer (and the Trustee, if
notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Trustee (or such other successor Servicer as is
approved in accordance with this Agreement) shall be the successor in all
respects to the Servicer in its capacity as servicer under this Agreement and
the transactions set forth or provided for herein and shall be subject to all
the responsibilities, duties and liabilities relating thereto placed on the
Servicer by the terms and provisions hereof arising on and after its succession;
except that the Trustee shall not be (i) liable for losses of the predecessor
Servicer pursuant to Section 3.04 or any acts or omissions of the predecessor
Servicer hereunder, (ii) obligated to effectuate repurchases or substitutions of
Mortgage Loans hereunder, (iii) responsible for expenses of the predecessor
Servicer pursuant to Section 2.03, (iv) obligated to make Advances if it is
prohibited from doing so by applicable law, (v) deemed to have made any
representations and warranties of the Servicer hereunder, or (vi) obligated to
perform any obligation of the Servicer under Sections 3.19, 3.20 or 3.29 of this
Agreement with respect to any period of time during which the Trustee was not
the Servicer. As compensation therefor, the Trustee (or such other successor
Servicer) shall be entitled to such compensation as the Servicer would have been
entitled to hereunder if no such notice of termination had been given.
Notwithstanding the above, (i) if the Trustee is unwilling to act as successor
Servicer or (ii) if the Trustee is legally unable so to act, the Trustee shall
appoint or petition a court of competent jurisdiction to appoint, any
established housing and home finance institution, bank or other mortgage loan or
home equity loan servicer having a net worth of not less than $50,000,000 as the
successor to the Servicer hereunder in the assumption of all or any part of

                                       127

<PAGE>

the responsibilities, duties or liabilities of the Servicer hereunder; provided,
that the appointment of any such successor Servicer will not result in the
qualification, reduction or withdrawal of the ratings assigned to the
Certificates or the ratings that are in effect by the Rating Agencies as
evidenced by a letter to such effect from the Rating Agencies. Pending
appointment of a successor to the Servicer hereunder, unless the Trustee is
prohibited by law from so acting, the Trustee shall act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
successor shall be entitled to receive compensation out of payments on Mortgage
Loans in an amount equal to the compensation which the Servicer would otherwise
have received pursuant to Section 3.18 (or such other compensation as the
Trustee and such successor shall agree, not to exceed the Servicing Fee). The
successor servicer shall be entitled to withdraw from the Collection Account all
costs and expenses associated with the transfer of the servicing to the
successor servicer. The appointment of a successor servicer shall not affect any
liability of the predecessor Servicer which may have arisen under this Agreement
prior to its termination as Servicer to pay any deductible under an insurance
policy pursuant to Section 3.12 or to indemnify the parties indicated in Section
3.26 pursuant to the terms thereof, nor shall any successor Servicer be liable
for any acts or omissions of the predecessor Servicer or for any breach by such
Servicer of any of its representations or warranties contained herein or in any
related document or agreement. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

     In the event of a Servicer Event of Termination, notwithstanding anything
to the contrary above, the Trustee and the Depositor hereby agree that upon
delivery to the Trustee by the Servicing Rights Pledgee of a letter signed by
the Servicer within ten Business Days of when notification of such event shall
have been provided to the Trustee, whereunder the Servicer shall resign as
Servicer under this Agreement, the Servicing Rights Pledgee or its designee
shall be appointed as successor Servicer (provided that at the time of such
appointment the Servicing Rights Pledgee or such designee meets the requirements
of a successor Servicer set forth above) and the Servicing Rights Pledgee agrees
to be subject to the terms of this Agreement.

          (b) Any successor, including the Trustee, to the Servicer as servicer
shall during the term of its service as servicer continue to service and
administer the Mortgage Loans for the benefit of Certificateholders, and
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and a
Fidelity Bond in respect of its officers, employees and agents to the same
extent as the Servicer is so required pursuant to Section 3.12.

     Section 7.03 Waiver of Defaults.

     The Holders of Certificates entitled to at least 66 2/3% of the Voting
Rights allocated to the Class of Certificates affected by a Servicer Event of
Termination may, on behalf of all Certificateholders, waive any events
permitting removal of the Servicer as servicer pursuant to this Article VII,
provided, however, that such Holders may not waive a default in making a
required distribution on a Certificate without the consent of the Holder of such
Certificate. Upon any waiver of a past default, such default shall cease to
exist and any Servicer Event of Termination arising therefrom shall be deemed to
have been remedied for every purpose of this Agreement. No such waiver shall
extend to any subsequent or other default or impair any right consequent thereto
except to the extent expressly so waived. Notice of any such waiver shall be
given by the Trustee to the Rating Agencies.

     Section 7.04 Notification to Certificateholders.

                                       128

<PAGE>

          (a) On any termination or appointment of a successor the Servicer
pursuant to this Article VII or Section 6.04, the Trustee shall give prompt
written notice thereof to the Certificateholders at their respective addresses
appearing in the Certificate Register and each Rating Agency.

          (b) No later than 60 days after the occurrence of any event which
constitutes or which, with notice or a lapse of time or both, would constitute a
Servicer Event of Termination for five Business Days after a Responsible Officer
of the Trustee becomes aware of the occurrence of such an event, the Trustee
shall transmit by mail to all Certificateholders notice of such occurrence
unless such default or Servicer Event of Termination shall have been waived or
cured. Such notice shall be given to the Rating Agencies promptly after any such
occurrence.

     Section 7.05 Survivability of Servicer Liabilities.

     Notwithstanding anything herein to the contrary, upon termination of the
Servicer hereunder, any liabilities of the Servicer which accrued prior to such
termination shall survive such termination.

                                  ARTICLE VIII

                                   THE TRUSTEE

     Section 8.01 Duties of Trustee.

     The Trustee, prior to the occurrence of a Servicer Event of Termination of
which a Responsible Officer of the Trustee shall have actual knowledge and after
the curing of all Servicer Events of Termination which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If a Servicer Event of Termination has occurred (which
has not been cured) of which a Responsible Officer has actual knowledge, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

     The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform on their face to the requirements of this Agreement to the extent
specified herein; provided, however, that that the Trustee shall not be
responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Servicer, the Seller or the Depositor hereunder. If any such instrument is found
not to conform in any material respect to the requirements of this Agreement,
the Trustee shall notify the Certificateholders of such instrument in the event
that the Trustee, after so requesting, does not receive a satisfactorily
corrected instrument.

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

               (i) prior to the occurrence of a Servicer Event of Termination,
and after the curing of all such Servicer Events of Termination which may have
occurred, the duties and obligations of the Trustee shall be determined solely
by the express provisions of this Agreement, the Trustee shall not be liable
except for the performance of such 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 and, in the absence of bad faith on the
part of the Trustee, the Trustee may conclusively rely, as to the truth of

                                       129

<PAGE>

the statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Trustee and conforming on their face
to the requirements of this Agreement to the extent specified herein;

               (ii) the Trustee shall not be liable for an error of judgment
made in good faith by a Responsible Officer of the Trustee unless it shall be
proved that the Trustee was negligent in ascertaining or investigating the facts
related thereto;

               (iii) the Trustee shall not be liable with respect to any action
taken, suffered or omitted to be taken by it in good faith in accordance with
the direction of the Majority Certificateholders relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising or omitting to exercise any trust or power conferred upon the
Trustee under this Agreement; and

               (iv) the Trustee shall not be charged with knowledge of any
failure by the Servicer to comply with the obligations of the Servicer referred
to in clauses (i) and (ii) of Section 7.01(a) or any Servicer Event of
Termination unless a Responsible Officer of the Trustee at the applicable
Corporate Trust Office obtains actual knowledge of such failure or the Trustee
receives written notice of such failure from the Servicer or the Majority
Certificateholders. In the absence of such receipt of such notice, the Trustee
may conclusively assume that there is no Servicer Event of Termination.

     The Trustee shall not 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 to perform, or be responsible for the manner of performance of, any
of the obligations of the Servicer under this Agreement, 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 Servicer in accordance with the
terms of this Agreement; provided, however, the Trustee shall not seek
reimbursement or repayment of any of its expenses from the Trust Fund except in
connection with expenses that would constitute "unanticipated expenses" under
Treasury Regulation 1.860G-1(b)(3)(ii).

     The Trustee shall not have any duty (A) to see to any recording, filing, or
depositing of this Agreement or any agreement referred to herein or any
financing statement or continuation statement evidencing a security interest, or
to see to the maintenance of any such recording or filing or depositing or to
any rerecording, refiling or redepositing of any thereof, (B) to see to any
insurance or (C) to see to the payment or discharge of any tax, assessment, or
other governmental charge or any lien or encumbrance of any kind owing with
respect to, assessed or levied against, any part of the Trust Fund other than
from funds available in the Distribution Account.

     The Trustee shall have no duty hereunder with respect to any complaint,
claim, demand, notice or other document it may receive or which may be alleged
to have been delivered to or served upon it by the parties as a consequence of
the assignment of any Mortgage Loan hereunder; provided, however, that the
Trustee shall promptly remit to the Servicer upon receipt any such complaint,
claim, demand, notice or other document (i) which is delivered to the Trustee at
its Corporate Trust Office; (ii) of which a Responsible Officer has actual
knowledge and (iii) which contains information sufficient to permit the Trustee
to make a determination that the real property to which such document relates to
is a Mortgaged Property.

<PAGE>

          (a) Except as otherwise provided in Section 8.01:

               (i) the Trustee may request and rely upon, and shall be protected
in acting or refraining from acting upon, any resolution, Officer's Certificate,
certificate of auditors or any other certificate, statement, instrument,
opinion, report, notice, request, consent, order, appraisal, bond or other paper
or document reasonably believed by it to be genuine and to have been signed or
presented by the proper party or parties;

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

               (iii) the Trustee shall not be under any obligation to exercise
any of the rights or powers vested in it by this Agreement, or to institute,
conduct or defend any litigation hereunder or in relation hereto, at the
request, order or direction 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; the right of the Trustee
to perform any discretionary act enumerated in this Agreement shall not be
construed as a duty, and the Trustee shall not be answerable for other than its
negligence or willful misconduct in the performance of any such act;

               (iv) the Trustee shall not be liable 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) prior to the occurrence of a Servicer Event of Termination
and after the curing of all Servicer Events of Termination which may have
occurred, the Trustee shall not 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 documents, unless requested in writing to do so by the Majority
Certificateholder; provided, however, that if the payment within a reasonable
time to the Trustee 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 not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Agreement, the Trustee may require reasonable indemnity against such cost,
expense or liability as a condition to such proceeding. The reasonable expense
of every such examination shall be paid by the Servicer or, if paid by the
Trustee shall be reimbursed by the Servicer upon demand. Nothing in this clause
(v) shall derogate from the obligation of the Servicer to observe any applicable
law prohibiting disclosure of information regarding the Mortgagors;

               (vi) the Trustee shall not be accountable, shall not have any
liability and shall not make any representation as to any acts or omissions
hereunder of the Servicer until such time as the Trustee may be required to act
as Servicer pursuant to Section 7.02;

               (vii) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys or a custodian and the Trustee shall not be responsible for
any misconduct or negligence on the part of any such agent, attorney or
custodian appointed by it with due care or with respect to the initial
custodian; and

               (viii) the right of the Trustee to perform any discretionary act
enumerated in this Agreement shall not be construed as a duty, and the Trustee
shall not be answerable for other than its negligence or willful misconduct in
the performance of such act.

     Section 8.03 Trustee Not Liable for Certificates or Mortgage Loans.

     The recitals contained herein and in the Certificates (other than the
authentication of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee does not assume any responsibility for
the correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the Certificates (other than the
signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or Related Document. The Trustee shall not be accountable for the
use or application by the Servicer, or for the use or application of any funds
paid to the Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Servicer. The Trustee shall not 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
or its ability to generate the payments to be distributed to Certificateholders
under this Agreement, including, without limitation: the existence, condition
and ownership of any Mortgaged Property; the existence and enforceability of any
hazard insurance thereon (other than if the Trustee shall assume the duties of
the Servicer pursuant to Section 7.02); the validity of the assignment of any
Mortgage Loan to the Trustee or of any intervening assignment; the completeness
of any Mortgage Loan; the performance or enforcement of any Mortgage Loan (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
7.02); the compliance by the Depositor, the Seller or the Servicer with any
warranty or representation made under this Agreement or in any related document
or the accuracy of any such warranty or representation prior to the Trustee's
receipt of notice or other discovery of any non-compliance therewith or any
breach thereof; any investment of monies by or at the direction of the Servicer
or any loss resulting therefrom; the acts or omissions of any of the Servicer
(other than if the Trustee shall assume the duties of the Servicer pursuant to
Section 7.02), or any Mortgagor; any action of the Servicer (other than if the
Trustee shall assume the duties of the Servicer pursuant to Section 7.02), taken
in the name of the Trustee; the failure of the Servicer to act or perform any
duties required of it as agent of the Trustee hereunder; or any action by the
Trustee taken at the instruction of the Servicer (other than if the Trustee
shall assume the duties of the Servicer pursuant to Section 7.02); provided,
however, that the foregoing shall not relieve the Trustee of its obligation to
perform its duties under this Agreement. The Trustee shall not have any
responsibility for filing any financing 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.

     Section 8.04 Trustee May Own Certificates.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Certificates with the same rights as it would have if it were not
Trustee and may transact any banking and trust business with the Seller, the
Servicer, the Depositor or their Affiliates.

     Section 8.05 Seller to Pay Trustee Fees and Expenses.

     The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself the Trustee Fee pursuant to Section 4.01(i)
and, to the extent the Interest Remittance Amount is at any time insufficient
for such purpose, the Seller shall pay such fees as reasonable compensation
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) for all services rendered by it
in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Trustee, and the
Seller will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee 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

                                       132

<PAGE>

regularly in its employ) except any such expense, disbursement or advance as may
arise from such party's negligence or bad faith or which is the responsibility
of Certificateholders, the Trustee hereunder. Notwithstanding any other
provision of this Agreement, including Section 2.03(a) and Section 2.04, to the
contrary, the Seller covenants and agrees to indemnify the Trustee and its
officers, directors, employees and agents from, and hold each of them harmless
against, any and all losses, liabilities, damages, claims or expenses incurred
in connection with (a) any legal action relating to this Agreement, the
Custodial Agreement, the Certificates or incurred in connection with the
administration of the Trust, other than with respect to a party, any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence of such party in the performance of its duties hereunder or by reason
of such party's reckless disregard of obligations and duties hereunder and (b)
the second paragraph of Section 2.01. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Trustee 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 has been advised of the likelihood
of such loss or damage and regardless of the form of action. The Trustee and any
director, officer, employee or agent of the Trustee shall be indemnified, to the
extent not paid by the Seller pursuant to this Section by the Trust Fund and
held harmless against any loss, liability or expense (not including expenses,
disbursements and advances incurred or made by the Trustee, in the ordinary
course of the Trustee's performance in accordance with the provisions of this
Agreement) incurred by the Trustee or such party arising out of or in connection
with the acceptance or administration of its duties under this Agreement, other
than in connection with the indemnification provided pursuant to clause (a)
above, any loss, liability or expense incurred by reason of willful misfeasance,
bad faith or negligence in the performance by the Trustee of its duties under
this Agreement or by reason of the reckless disregard of the Trustee's
obligations and duties under this Agreement. This section shall survive
termination of this Agreement or the resignation or removal of any Trustee
hereunder.

     Section 8.06 Eligibility Requirements for Trustee.

     The Trustee hereunder shall at all times be a Department of Housing and
Urban Development and Federal Housing Administration approved mortgagee, an
entity duly organized and validly existing under the laws of the United States
of America or any state thereof, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000 and a minimum long-term debt rating of BBB by Fitch and S&P, a long
term debt rating of at least A1 or better by Moody's, and a minimum short term
debt rating of at least A1 by S&P, and subject to supervision or examination by
federal or state authority. If such entity 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 8.06,
the combined capital and surplus of such entity shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. The principal office of the Trustee (other than the initial
Trustee) shall be in a state with respect to which an Opinion of Counsel has
been delivered to such Trustee at the time such Trustee is appointed Trustee to
the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 8.06, the Trustee shall resign immediately
in the manner and with the effect specified in Section 8.07.

     Section 8.07 Resignation or Removal of Trustee.

     The Trustee may at any time resign and be discharged from the trusts hereby
created by giving written notice thereof to the Depositor, the Servicer and each
Rating Agency. Upon receiving such notice of resignation, the Depositor shall
promptly appoint a successor Trustee, by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor Trustee. If no successor Trustee shall have been so
appointed and having accepted appointment

<PAGE>

within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

     If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 8.06 and shall fail to resign after written request
therefor by the Depositor, or if at any time the Trustee shall be legally unable
to act, or shall be adjudged a bankrupt or insolvent, or a receiver of the
Trustee or of its property shall be appointed, or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation, then the Depositor may remove
the Trustee. If the Depositor or the Servicer removes the Trustee under the
authority of the immediately preceding sentence, the Depositor shall promptly
appoint a successor Trustee by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Trustee so removed and one copy to
the successor Trustee.

     The Majority Certificateholders may at any time remove the Trustee by
written instrument or instruments delivered to the Servicer, the Depositor and
the Trustee; the Depositor shall thereupon use its best efforts to appoint a
successor Trustee in accordance with this Section.

     Any resignation or removal of the Trustee and appointment of a successor
Trustee pursuant to any of the provisions of this Section 8.07 shall not become
effective until acceptance of appointment by the successor Trustee as provided
in Section 8.08.

     Section 8.08 Successor Trustee.

     Any successor Trustee appointed as provided in Section 8.07 shall execute,
acknowledge and deliver to the Depositor, the Rating Agencies, the Servicer and
to its predecessor Trustee an instrument accepting such appointment hereunder,
and thereupon the resignation or removal of the predecessor Trustee shall become
effective, and such successor Trustee, 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. The Depositor, the Servicer and the predecessor Trustee shall
execute and deliver such instruments and do such other things as may reasonably
be required for fully and certainly vesting and confirming in the successor
Trustee all such rights, powers, duties and obligations.

     No successor Trustee shall accept appointment as provided in this Section
8.08 unless at the time of such acceptance such successor Trustee shall be
eligible under the provisions of Section 8.06 and the appointment of such
successor Trustee shall not result in a downgrading of the Regular Certificates
by either Rating Agency, as evidenced by a letter from each Rating Agency.

     Upon acceptance of appointment by a successor Trustee as provided in this
Section 8.08, the successor Trustee shall mail notice of the appointment of a
successor Trustee hereunder to all Holders of Certificates at their addresses as
shown in the Certificate Register and to each Rating Agency.

     Section 8.09 Merger or Consolidation of Trustee.

     Any entity into which the Trustee may be merged or converted or with which
it may be consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any entity succeeding to
the business of the Trustee, shall be the successor of the Trustee hereunder,
provided such entity shall be eligible under the provisions of Section 8.06 and
8.08, 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 8.10 Appointment of Co-Trustee or Separate Trustee.

     Notwithstanding any other provisions of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust or any Mortgaged Property 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 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 and for the benefit of the
Certificateholders, such title to the Trust, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties, obligations,
rights and trusts as the Servicer and the Trustee may consider necessary or
desirable. Any such co-trustee or separate trustee shall be subject to the
written approval of the Servicer. If the Servicer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
the case a Servicer Event of Termination shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee hereunder shall be required to meet the terms of eligibility
as a successor Trustee under Section 8.06, and no notice to Certificateholders
of the appointment of any co-trustee or separate trustee shall be required under
Section 8.08. The Servicer shall be responsible for the fees of any co-trustee
or separate trustee appointed hereunder.

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

               (i) all rights, powers, duties and obligations conferred or
imposed upon the Trustee shall be conferred or imposed upon and exercised or
performed by the Trustee and such separate trustee or co-trustee jointly (it
being understood that such separate trustee or co-trustee is not authorized to
act separately without the Trustee joining in such act), except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the 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 singly by such separate trustee
or co-trustee, but solely at the direction of the Trustee;

               (ii) no trustee hereunder shall be held personally liable by
reason of any act or omission of any other trustee hereunder; and

               (iii) the Servicer and the Trustee, acting jointly may at any
time accept the resignation of or remove any separate trustee or co-trustee
except that following the occurrence of a Servicer Event of Termination, the
Trustee acting alone may accept the resignation or remove any separate trustee
or co-trustee.

     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 VIII. 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 and a copy thereof given to the
Depositor, the Rating Agencies and the Servicer.

                                       135

<PAGE>

     Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
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.

     Section 8.11 Limitation of Liability.

     The Certificates are executed by the Trustee, not in its individual
capacity but solely as Trustee of the Trust, in the exercise of the powers and
authority conferred and vested in it by this Agreement. Each of the undertakings
and agreements made on the part of the Trustee in the Certificates is made and
intended not as a personal undertaking or agreement by the Trustee but is made
and intended for the purpose of binding only the Trust.

     Section 8.12 Trustee May Enforce Claims Without Possession of Certificates.

          (a) All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee for the benefit of all
Holders of such Certificates, subject to the provisions of this Agreement. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Certificateholders in respect of
which such judgment has been recovered.

          (b) The Trustee shall afford the Seller, the Depositor, the Servicer
and each Certificateholder upon reasonable notice during normal business hours,
access to all records maintained by the Trustee in respect of its duties
hereunder and access to officers of the Trustee responsible for performing such
duties. The Trustee shall cooperate fully with the Seller, the Servicer, the
Depositor and such Certificateholder and shall make available to the Seller, the
Servicer, the Depositor and such Certificateholder for review and copying at the
expense of the party requesting such copies, such books, documents or records as
may be requested with respect to the Trustee's duties hereunder. The Seller, the
Depositor, the Servicer and the Certificateholders shall not have any
responsibility or liability for any action or failure to act by the Trustee and
are not obligated to supervise the performance of the Trustee under this
Agreement or otherwise.

     Section 8.13 Suits for Enforcement.

     In case a Servicer Event of Termination or other default by the Servicer or
the Seller hereunder shall occur and be continuing, the Trustee may proceed to
protect and enforce its rights and the rights of the Certificateholders under
this Agreement by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this Agreement
or for the enforcement of any other legal, equitable or other remedy, as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual to protect and enforce any of the rights of the Trustee and the
Certificateholders.

     Section 8.14 Waiver of Bond Requirement.

                                       136

<PAGE>

     The Trustee shall be relieved of, and each Certificateholder hereby waives,
any requirement of any jurisdiction in which the Trust, or any part thereof, may
be located that the Trustee post a bond or other surety with any court, agency
or body whatsoever.

     Section 8.15 Waiver of Inventory, Accounting and Appraisal Requirement.

     The Trustee shall be relieved of, and each Certificateholder hereby waives,
any requirement of any jurisdiction in which the Trust, or any part thereof, may
be located that the Trustee file any inventory, accounting or appraisal of the
Trust with any court, agency or body at any time or in any manner whatsoever.

                                   ARTICLE IX

                     REMIC AND GRANTOR TRUST ADMINISTRATION

     Section 9.01 REMIC Administration.

          (a) The Trustee shall make or cause to be made REMIC elections for
each of REMIC 1, REMIC 2, REMIC M-5, REMIC M-6, REMIC B-1, REMIC B-2, REMIC B-3,
REMIC B-4, REMIC B-5, the SWAP REMIC, REMIC IO, REMIC CE-1 and REMIC CE-2 as set
forth in the Preliminary Statement on Forms 1066 or other appropriate federal
tax or information return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued. The regular interests and
residual interest in each REMIC shall be as designated in the Preliminary
Statement.

          (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 860G(a)(9) of the Code.

          (c) The Servicer shall pay any and all tax related expenses (not
including taxes) of each REMIC, including but not limited to any professional
fees or expenses related to audits or any administrative or judicial proceedings
with respect to such REMIC that involve the Internal Revenue Service or state
tax authorities, but only to the extent that (i) such expenses are ordinary or
routine expenses, including expenses of a routine audit but not expenses of
litigation (except as described in (ii)); or (ii) such expenses or liabilities
(including taxes and penalties) are attributable to the negligence or willful
misconduct of the Servicer in fulfilling its duties hereunder. The Servicer
shall be entitled to reimbursement of expenses to the extent provided in clause
(i) above from the Collection Account, but only to the extent that such expenses
are "unanticipated expenses" under Treasury Regulations Section
1.860G-1(b)(3)(ii).

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

          (e) The Holder of the Residual Certificates with respect to each REMIC
holding the largest Percentage Interest shall be the "tax matters person" as
defined in the REMIC Provisions (the "Tax Matters Person") with respect to the
applicable REMIC or REMICs, and the Trustee is irrevocably designated as and
shall act as attorney-in-fact and agent for such Tax Matters Person for each
REMIC. The Trustee, as agent for the Tax Matters Person, shall perform, on
behalf of each REMIC, all reporting and other tax compliance duties that are the
responsibility of such REMIC under the Code, the REMIC Provisions, or other
compliance guidance issued by the Internal Revenue Service or any state or local
taxing authority. Among its other duties, if required by the Code, the REMIC
Provisions, or other such

                                       137

<PAGE>

guidance, the Trustee, as agent for the Tax Matters Person, shall provide (i) to
the Treasury or other governmental authority such information as is necessary
for the application of any tax relating to the transfer of a Residual
Certificate to any disqualified person or organization and (ii) to the
Certificateholders such information or reports as are required by the Code or
REMIC Provisions.

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

          (g) Each Holder of a Residual Certificate shall pay when due its pro
rata share of any and all taxes imposed on any REMIC by federal or state
governmental authorities. To the extent that such REMIC taxes are not paid by
Residual Certificateholders, the Trustee shall pay any remaining REMIC taxes out
of current or future amounts otherwise distributable to the Holder of the
Residual Certificate in each REMIC or, if no such amounts are available, out of
other amounts held in the Collection Account, and shall reduce amounts otherwise
payable to Holders of the REMIC Regular Interests or the Certificates, as the
case may be.

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

          (i) No additional contributions of assets shall be made to any REMIC,
except as expressly provided in this Agreement with respect to Eligible
Substitute Mortgage Loans.

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

          (k) On or before April 15 of each calendar year beginning in 2008, the
Servicer shall deliver to the Trustee and each Rating Agency an Officer's
Certificate stating the Servicer's compliance with the provisions of this
Section 9.01.

          (l) (i) It is intended that the rights of each Class of the Class A,
Class M and Class B Certificates to receive payments in respect of Excess
Interest shall be treated as a right in interest rate cap contracts written by
the Class CE-1 Certificateholders in favor of the holders of each Class of the

                                       138

<PAGE>

Class A, Class M and Class B Certificates and such shall be accounted for as
property held separate and apart from the regular interests in REMIC 2 held by
the holders of the Class A, Class M-1, Class M-2, Class M-3 and Class M-4
Certificates, the regular interest in REMIC M-5 held by the holders of the Class
M-5 Certificates, the regular interest in REMIC M-6 held by the holders of the
Class M-6 Certificates, the regular interest in REMIC B-1 held by the holders of
the Class B-1 Certificates, the regular interest in REMIC B-2 held by the
holders of the Class B-2 Certificates, the regular interest in REMIC B-3 held by
the holders of the Class B-3 Certificates, the regular interest in REMIC B-4
held by the holders of the Class B-4 Certificates and the regular interest in
REMIC B-5 held by the holders of the Class B-5 Certificates. For information
reporting requirements, the rights of the Class A, Class M and Class B
Certificates to receive payments in respect of Excess Interest shall be assumed
to have zero or a de minimis value. This provision is intended to satisfy the
requirements of Treasury Regulations Section 1.860G-2(i) for the treatment of
property rights coupled with REMIC interests to be separately respected and
shall be interpreted consistently with such regulation. On each Distribution
Date, to the extent that any of the Class A, Class M and Class B Certificates
receive payments in respect of Excess Interest, such amounts, to the extent not
derived from payments on the Swap Agreement, will be treated as distributed by
REMIC CE-1 to the Class CE-1 Certificates pro rata and then paid to the relevant
Class of Certificates pursuant to the related interest rate cap agreement.

               (ii) It is intended that the beneficial owners of the
Certificates (other than the Class P, Class CE-1, Class CE-2 and Residual
Certificates) shall be treated as having entered into a notional principal
contract with respect to the beneficial owners of the Class CE-1 Certificates.
Pursuant to each such notional principal contract, all beneficial owners of each
Class of Certificates (other than the Class P, Class CE-1, Class CE-2 and
Residual Certificates) shall be treated as having agreed to pay, on each
Distribution Date, to the beneficial owners of the Class CE-1 Certificates an
aggregate amount equal to the excess, if any, of (i) the amount payable on such
Distribution Date on the Corresponding REMIC 2 Regular Interest of such Class of
Certificates over (ii) the amount payable on such Class of Certificates on such
Distribution Date (such excess, a "Class Payment Shortfall"). A Class Payment
Shortfall shall be allocated to each Class of Certificates to the extent that
interest accrued on such Class for the related Interest Accrual Period at the
Pass-Through Rate for a Class, computed by substituting "REMIC 2 Net WAC Cap"
for the related Net WAC Cap set forth in the definition thereof, exceeds the
amount of interest accrued on such Certificate at the Pass-Through Rate (without
such substitution) for the related Interest Accrual Period, and a Class Payment
Shortfall payable from principal collections shall be allocated to the most
subordinate Class of Certificates with an outstanding principal balance to the
extent of such balance.

          (m) The parties intend that the portion of the Trust Fund consisting
of the uncertificated REMIC CE-1 CE-1 Interest, the uncertificated REMIC IO IO
Interest, the rights to receive payments deemed made by the Class A, Class M and
Class B Certificates in respect of notional principal contracts described in
Section 9.01(l)(ii), the Supplemental Interest Trust which holds the Swap
Agreement and the obligation of the holders of the Class CE-1 Certificates to
pay amounts in respect of Excess Interest to the holders of the Class A, Class M
and Class B Certificates shall be treated as a "grantor trust" under the Code,
for the benefit of the holders of the Class CE-1 Certificates, and the
provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class CE-1 Certificates information regarding
their allocable share, if any, of the income with respect to such grantor trust,
(ii) file or cause to be filed with the Internal Revenue Service Form 1041
(together with any necessary attachments) and such other forms as may be
applicable and (iii) comply with such information reporting obligations with
respect to payments from such grantor trust to the holders of Class A, Class M,
Class B and Class CE-1 Certificates as may be applicable under the Code.

                                       139

<PAGE>

          (n) The parties intend that the portion of the Trust Fund consisting
of the right to receive amounts distributable to the Class P Certificates
pursuant to Section 4.01 hereof shall be treated as a "grantor trust" under the
Code, for the benefit of the holders of the Class P Certificates, and the
provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class P Certificates information regarding their
allocable share of the income with respect to such grantor trust and (ii) file
or cause to be filed with the Internal Revenue Service Form 1041 (together with
any necessary attachments) and such other forms as may be applicable.

          (o) The parties intend that amounts paid to the Swap Counterparty
under the Swap Agreement shall be deemed for federal income tax purposes to be
paid by the Class CE-1 Certificates first, out of funds deemed received in
respect of the REMIC IO IO Interest, second, out of funds deemed received in
respect of the REMIC CE-1 CE-1 Interest and third, out of funds deemed received
in respect of notional principal contracts described in Section 9.01(l)(ii), and
the provisions hereof shall be interpreted consistently with this intention. On
each Distribution Date, to the extent that amounts paid to the Swap Counterparty
are deemed paid out of funds received in respect of the REMIC IO IO Interest or
the REMIC CE-1 CE-1 Interest, such amounts will be treated as distributed by
REMIC IO or REMIC CE-1, respectively, to the Class CE-1 Certificates pro rata
and then paid to the Swap Counterparty pursuant to the Swap Agreement.

     The Supplemental Interest Trust shall be an "outside reserve fund" for
federal income tax purposes and not an asset of any REMIC. Furthermore, the
Holders of the Class CE-1 Certificates shall be the beneficial owners of the
Supplemental Interest Trust for all federal income tax purposes, and shall be
taxable on all income earned thereon.

          (p) REMIC CE-2. All amounts deemed distributed in respect of the REMIC
2 CE-2 Interest shall be treated as received by REMIC CE-2 and then distributed
by REMIC CE-2 in respect of the Class CE-2 Certificates.

          (q) REMIC IO. All amounts deemed distributed in respect of the REMIC 2
IO Interest shall be treated as received by REMIC IO and then distributed by
REMIC IO in respect of the REMIC IO IO Interest.

          (r) REMIC CE-1. All amounts deemed distributed in respect of the REMIC
2 CE-1 Interest shall be treated as received by REMIC CE-1 and then distributed
by REMIC CE-1 in respect of the REMIC CE-1 CE-1 Interest. All allocations of
Realized Losses to the REMIC 2 CE-1 Interest shall result in similar allocations
to the REMIC CE-1 CE-1 Interest.

          (s) REMIC M-5. All amounts deemed distributed in respect of the REMIC
2 M-5 Interest shall be treated as received by REMIC M-5 then distributed by
REMIC M-5 in respect of the REMIC M-5 M-5 Interest. All allocations of Applied
Realized Loss Amounts and Realized Loss Amortization Amounts to the REMIC 2 M-5
Interest shall result in similar allocations to the REMIC M-5 M-5 Interest. If
on any Distribution Date the Certificate Principal Balance of the Class M-5
Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amount of the REMIC M-5 M-5 Interest on such Distribution Date.

          (t) REMIC M-6. All amounts deemed distributed in respect of the REMIC
2 M-6 Interest shall be treated as received by REMIC M-6 then distributed by
REMIC M-6 in respect of the REMIC M-6 M-6 Interest. All allocations of Applied
Realized Loss Amounts and Realized Loss

                                       140

<PAGE>

Amortization Amounts to the REMIC 2 M-6 Interest shall result in similar
allocations to the REMIC M-6 M-6 Interest. If on any Distribution Date the
Certificate Principal Balance of the Class M-6 Certificates is increased
pursuant to the last sentence of the definition of "Certificate Principal
Balance", then there shall be an equivalent increase in the principal amount of
the REMIC M-6 M-6 Interest on such Distribution Date.

          (u) REMIC B-1. All amounts deemed distributed in respect of the REMIC
2 B-1 Interest shall be treated as received by REMIC B-1 then distributed by
REMIC B-1 in respect of the REMIC B-1 B-1 Interest. All allocations of Applied
Realized Loss Amounts and Realized Loss Amortization Amounts to the REMIC 2 B-1
Interest shall result in similar allocations to the REMIC B-1 B-1 Interest. If
on any Distribution Date the Certificate Principal Balance of the Class B-1
Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amount of the REMIC B-1 B-1 Interest on such Distribution Date.

          (v) REMIC B-2. All amounts deemed distributed in respect of the REMIC
2 B-2 Interest shall be treated as received by REMIC B-2 then distributed by
REMIC B-2 in respect of the REMIC B-2 B-2 Interest. All allocations of Applied
Realized Loss Amounts and Realized Loss Amortization Amounts to the REMIC 2 B-2
Interest shall result in similar allocations to the REMIC B-2 B-2 Interest. If
on any Distribution Date the Certificate Principal Balance of the Class B-2
Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amount of the REMIC B-2 B-2 Interest on such Distribution Date.

Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amount of the REMIC B-5 B-5 Interest on such Distribution Date.

          (z) REMIC 2. On each Distribution Date, REMIC 2 shall be deemed to
have received the amounts deemed distributed in respect of the REMIC 1 Regular
Interests. Principal, interest, shortfalls and Realized Losses shall be deemed
paid to and allocated among the REMIC 2 Regular Interests in the same manner as
such items (other than payments to the Cap Carryover Certificates in respect of
Excess Interest and disregarding the deemed obligation to make payments in
respect of Class Payment Shortfalls) are paid or allocated in respect of the
related Certificates (the REMIC 2 A-1A Interest being related to the Class A-1A
Certificates, the REMIC 2 A-1B Interest being related to the Class A-1B
Certificates, the REMIC 2 A-1C Interest being related to the Class A-1C
Certificates, the REMIC 2 A-2A Interest being related to the Class A-2A
Certificates, the REMIC 2 A-2B Interest being related to the Class A-2B

Certificates, and the REMIC 2 B-5 Interest being related to the Class B-5
Certificates). Amounts shall be deemed paid and allocated to the REMIC 2 CE-2
Interest equal to amounts paid and allocated to the Class LT1-CE2 Interest.
Amounts shall be deemed paid and allocated to the REMIC 2 IO Interest equal to
amounts paid and allocated to the Class LT1-IO Interest. On each Distribution
Date, principal shall be paid to, Realized Losses shall be allocated to and
accrued but unpaid interest shall be added to the principal amount of the REMIC
2 CE-1 Interest so that such principal amount shall equal the excess of (i) the
Pool Balance as of the close of the related Collection Period over (ii) the
aggregate Certificate Principal Balance of each Class of Certificates on such
Distribution Date after all principal payments have been made and Realized
Losses have been allocated to such Certificates (other than the Class CE-1
Certificates). The portion of Available Funds remaining in REMIC 2 on a
Distribution Date after all distributions have been made to the REMIC 2 Regular
Interests shall be distributed to the Class R Certificates in respect of the
Class R-2 Interest. If on any Distribution Date the Certificate Principal
Balance of any Class of Certificates is increased pursuant to the last sentence
of the definition of "Certificate Principal Balance", then there shall be an
equivalent increase in the principal amounts of the REMIC 2 Regular Interests,
with each Corresponding REMIC 2 Regular Interest having an increase in its
principal amount equal to the increase in the Certificate Principal Balance of
the Corresponding Cap Carryover Certificates.

          (aa) REMIC 1. On each Distribution Date, REMIC 1 shall be deemed to
have received the amounts deemed distributed in respect of the SWAP REMIC
Regular Interests. Amounts with respect to interest shall accrue on the REMIC 1
Regular Interests at the rates specified in the Preliminary Statement. Payments
and Realized Losses shall be allocated among the REMIC 1 Regular Interests so
that (i) each of the Marker I Interests shall have a principal balance equal to
25% of the principal balance of the related REMIC 2 Regular Interest (with, for
purposes of this Section 9.01(aa), the REMIC 2 A-1A Interest being related to
the Class LT1-A1A Interest, the REMIC 2 A-1B Interest being related to the Class

Interest, the REMIC 2 B-1 Interest being related to the Class LT1-B1 Interest,
the REMIC 2 B-2 Interest being related to the Class LT1-B2 Interest, the REMIC 2
B-3 Interest being related to the Class LT1-B3 Interest the REMIC 2 B-4 Interest
being related to the Class LT1-B4 Interest, and the REMIC 2 B-5 Interest being
related to the Class LT1-B-5 Interest), (ii) the Class LT1-X1 Interest has a
principal balance equal to the excess of (x) 50% of the remaining principal
balance of the Mortgage Loans over (y) the aggregate principal balance of the
Marker I Interests (if necessary to reflect an increase in
overcollateralization, accrued and unpaid interest on the Class LT1-X1 interest
may be added to its principal amount to achieve this result) and (iii) the
aggregate principal amount of the Class LT1-IA Interest, Class LT1-IB Interest,
Class LT1-IIA Interest, Class LT1-IIB Interest and the Class LT1-X2 Interest
shall equal 50% of the remaining principal balance of the Mortgage Loans.
Distributions and Realized Losses allocated to the REMIC 1 Regular Interests
described in clause (iii) of the preceding sentence will be allocated among such
REMIC 1 Regular Interests in the following manner: (x) distributions shall be
deemed made to such REMIC 1 Regular Interests first, so as to keep the principal
balance of the each such REMIC 1 Regular Interest with "B" at the end of its
designation equal to 0.005% of the aggregate scheduled principal balance of the
Mortgage Loans in the Related Loan Group; second, to such REMIC 1 Regular
Interests with "A" at the end of its designation so that the uncertificated
principal balance of each such REMIC 1 Regular Interest is equal to 0.005% of
the excess of (I) the aggregate scheduled principal balance of the Mortgage
Loans in the Related Loan Group over (II) the aggregate principal balance of the
Class A-1 Certificates, in the case of Loan Group I, or the Class A-2
Certificates, in the case of Loan Group II (except that if 0.005% of any such
excess is greater than the principal amount of the corresponding REMIC 1 Regular
Interest with "A" at the end of its designation, the least amount of principal
shall be distributed to such REMIC 1 Regular Interests with "A" at the end of
its designation such that the REMIC 1 Subordinated Balance Ratio is maintained)
and finally, any remaining distributions of principal to the Class LT1-X2
Interest and (y) Realized Losses shall be allocated among the REMIC 1 Regular
Interests described in clause (iii) of the preceding sentence in the following
manner: (x) Realized Losses shall be deemed allocated to such REMIC 1 Regular
Interests first, so as to keep the principal balance of the each such REMIC 1
Regular Interest with "B" at the end of its designation equal to 0.005% of the
aggregate scheduled principal balance of the Mortgage Loans in the Related Loan
Group; second, to such REMIC 1 Regular Interests with "A" at the end of its
designation so that the uncertificated principal balance of each such REMIC 1
Regular Interest is equal to 0.005% of the excess of (I) the aggregate scheduled
principal balance of the Mortgage Loans in the Related Loan Group over (II) the
aggregate principal balance of the Class A-1Certificates, in the case of Loan
Group I, or the Class A-2 Certificates, in the case of Loan Group II (except
that if 0.005% of any such excess is greater than the principal amount of the
corresponding REMIC 1 Regular Interest with "A" at the end of its designation,
the least amount of Realized Losses shall be allocated to such REMIC 1 Regular
Interests with "A" at the end of its designation such that the REMIC 1
Subordinated Balance Ratio is maintained) and finally, any remaining Realized
Losses to the Class LT1-X2 Interest. Notwithstanding the preceding two
sentences, however, Realized Losses not allocated to any Class of Certificates
will not be allocated to any REMIC 1 Regular Interests. All computations with
respect to the REMIC 1 Regular Interests shall be taken out to ten decimal
places. Any portion of Available Funds remaining in REMIC 1 on a Distribution
Date after distributions to the REMIC 1 Regular Interests shall be distributed
to the Class R Certificates in respect of the Class R-1 Interest. If on any
Distribution Date the Certificate Principal Balance of any Class of Certificates
is increased pursuant to the last sentence of the definition of "Certificate
Principal Balance", then there shall be an equivalent increase in the principal
amounts of the REMIC 1 Regular Interests, with such increase allocated (before
the making of distributions and the allocation of losses on the REMIC 1 Regular
Interests on such Distribution Date) among the REMIC 1 Regular Interests so
that, to the greatest extent possible, (i) each of the Marker I Interests has a
principal balance equal to 25% of the principal balance of the related REMIC 2
Regular Interest, (ii) the Class LT1-X1 Interest has a principal balance equal
to the excess of (x) 50% of the remaining principal balance of the Mortgage
Loans over (y) the aggregate principal balance of the Marker I Interests and
(iii) the aggregate principal

                                       143

<PAGE>

amount of the Class LT1-IA Interest, Class LT1-IB Interest, Class LT1-IIA
Interest, Class LT1-IIB Interest and Class LT1-X2 Interest shall equal 50% of
the remaining principal balance of the Mortgage Loans. Allocations in connection
with clause (iii) shall be made so that, to the greatest extent possible, (a)
the principal balance of each such REMIC 1 Regular Interest with "B" at the end
of its designation equals 0.005% of the aggregate scheduled principal balance of
the Mortgage Loans in Related Loan Group, (b) the principal balance of each such
REMIC 1 Regular Interest with "A" at the end of its designation equals 0.005% of
the excess of (x) the aggregate scheduled principal balance of the Mortgage
Loans in Related Loan Group over (y) the aggregate principal balance of the
Class A-1 Certificates in the case of the Class LT1-IA Interest, or the Class
A-2 Certificates in the case of the Class LT1-IIA Interest and (c) any remaining
allocations are made to the Class LT1-X2 Interest.

          (bb) The SWAP REMIC. The Class SW-CE2 Interest shall be entitled to
distributions from the SWAP REMIC in the same amounts as all distributions on
the Class CE-2 Certificates. All payments of principal and interest at the Net
Mortgage Interest Rate on each of the Mortgage Loans (other than amounts
distributable to the Class P Certificates pursuant to Section 4.01 hereof)
received by the SWAP REMIC with respect to the Mortgage Loans shall be paid to
the SWAP REMIC Regular Interests until the principal balance of all such
interests have been reduced to zero and any losses allocated to such interests
have been reimbursed. Any available funds remaining in the SWAP REMIC on a
Distribution Date after distributions to the SWAP REMIC Regular Interests shall
be distributed to the Class R Certificates on account of the Class R-SW
Interest. On each Distribution Date, the Trustee shall distribute the aggregate
Interest Remittance Amount (net of expenses (other than any Net Swap Payment or
Swap Termination Payment made to the Swap Counterparty) and payments to the
Class P Certificates) with respect to each of the SWAP REMIC Regular Interests
(other than the Class SW-CE2 Interest) based on the interest rates for each such
SWAP REMIC Regular Interest. On each Distribution Date, the Trustee shall
distribute the aggregate Group I Principal Remittance Amount first to the Class
1-SW1 Interest until its principal balance is reduced to zero and then
sequentially to each of the other SWAP REMIC Regular Interests (other than the
Class SW-CE2 Interest) beginning with the designation "1" in ascending order of
their numerical class designation, in equal amounts to each such class in such
numerical designation, until the principal balance of each such class is reduced
to zero. All losses with respect to Loan Group I shall be allocated among the
SWAP REMIC Regular Interests beginning with designation "1" in the same manner
that principal distributions are allocated. On each Distribution Date, the
Trustee shall distribute the aggregate Group II Principal Remittance Amount
first to the Class 2-SW2 Interest until its principal balance is reduced to zero
and then sequentially to each of the other SWAP REMIC Regular Interests (other
than the Class SW-CE2 Interest) beginning with the designation "2" in ascending
order of their numerical class designation, in equal amounts to each such class
in such numerical designation, until the principal balance of each such class is
reduced to zero. All losses with respect to Loan Group II shall be allocated
among the SWAP REMIC Regular Interests beginning with designation "2" in the
same manner that principal distributions are allocated. Subsequent Recoveries
and loss reimbursements with respect to Loan Group I and Loan Group II shall be
allocated in the reverse fashion from the manner in which losses are allocated.

          (cc) Notwithstanding anything to the contrary contained herein, the
above distributions in this Section 9.01 (other than on the Certificates) are
deemed distributions, and distributions of funds from the Distribution Account
shall be made only in accordance with Sections 4.01 and 4.02 hereof.

     Section 9.02 Prohibited Transactions and Activities.

     Neither the Seller, the Depositor, the Servicer nor the Trustee shall sell,
dispose of, or substitute for any of the Mortgage Loans, except in a disposition
pursuant to (i) the foreclosure of a Mortgage Loan,

                                       144

<PAGE>

(ii) the bankruptcy of the Trust Fund, (iii) the termination of any REMIC
pursuant to Article X of this Agreement, (iv) a substitution pursuant to Article
II of this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article
II of this Agreement, nor acquire any assets for any REMIC constituting part of
the Trust Fund, nor sell or dispose of any investments in the Distribution
Account for gain, nor accept any contributions to any REMIC constituting part of
the Trust Fund after the Closing Date, unless it has received an Opinion of
Counsel (at the expense of the party causing such sale, disposition, or
substitution) that such disposition, acquisition, substitution, or acceptance
will not (a) affect adversely the status of such REMIC as a REMIC or of the
interests therein other than the Residual Certificates as the regular interests
therein, (b) affect the distribution of interest or principal on the
Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
or (d) cause such REMIC to be subject to a tax on prohibited transactions or
prohibited contributions pursuant to the REMIC Provisions.

     Section 9.03 Indemnification with Respect to Certain Taxes and Loss of
REMIC Status.

     In the event that any REMIC formed hereunder fails to qualify as a REMIC,
loses its status as a REMIC, or incurs federal, state or local taxes as a result
of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Servicer of its duties and
obligations set forth herein, the Servicer shall indemnify the Holder of the
related Residual Certificate against any and all losses, claims, damages,
liabilities or expenses ("Losses") resulting from such negligence; provided,
however, that the Servicer shall not be liable for any such Losses attributable
to the action or inaction of the Trustee, the Depositor or the Holder of such
Residual Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Residual Certificate on which the
Servicer has relied. The foregoing shall not be deemed to limit or restrict the
rights and remedies of the Holder of such Residual Certificate now or hereafter
existing at law or in equity. Notwithstanding the foregoing, however, in no
event shall the Servicer have any liability (1) for any action or omission that
is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by the Servicer of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

     Section 9.04 REO Property.

          (a) Subject to compliance with applicable laws and regulations as
shall at any time be in force, and notwithstanding any other provision of this
Agreement, the Servicer, acting on behalf of the Trust hereunder, shall not
rent, lease, or otherwise earn income on behalf of any REMIC constituting part
of the Trust Fund with respect to any REO Property which might cause such REO
Property to fail to qualify as "foreclosure" property within the meaning of
section 860G(a)(8) of the Code or result in the receipt by any REMIC
constituting part of the Trust Fund of any "income from non-permitted assets"
within the meaning of section 860F(a)(2) of the Code or any "net income from
foreclosure property" which is subject to tax under the REMIC Provisions unless
the Servicer has advised the Trustee in writing to the effect that, under the
REMIC Provisions, such action would not adversely affect the status of any REMIC
constituting part of the Trust Fund as a REMIC and any income generated for such
REMIC by the REO Property would not result in the imposition of a tax upon such
REMIC.

          (b) The Servicer shall make reasonable efforts to sell any REO
Property for its fair market value. In any event, however, the Servicer shall
dispose of any REO Property before the close of the third calendar year
beginning after the year of its acquisition by the Trust Fund unless the
Servicer has received a grant of extension from the Internal Revenue Service to
the effect that, under the REMIC

                                       145

<PAGE>

Provisions and any relevant proposed legislation and under applicable state law,
any REMIC constituting part of the Trust Fund may hold REO Property for a longer
period without adversely affecting its REMIC status or causing the imposition of
a Federal or state tax upon any REMIC. If the Servicer has received such an
extension, then the Servicer shall continue to attempt to sell the REO Property
for its fair market value as determined in good faith by the Servicer for such
longer period as such extension permits (the "Extended Period"). If the Servicer
has not received such an extension and the Servicer is unable to sell the REO
Property within 33 months after its acquisition by the Trust Fund or if the
Servicer has received such an extension, and the Servicer is unable to sell the
REO Property within the period ending three months before the close of the
Extended Period, the Servicer shall, before the end of the applicable period,
(i) purchase such REO Property at a price equal to the REO Property's fair
market value as determined in good faith by the Servicer or (ii) auction the REO
Property to the highest bidder (which may be the Servicer) in an auction
reasonably designed to produce a fair price prior to the expiration of the
applicable period.

                                   TERMINATION

     Section 10.01 Termination.

          (a) The respective obligations and responsibilities of the Seller, the
Servicer, the Depositor, the Trustee and the Certificate Registrar created
hereby (other than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate upon
notice to the Trustee upon the earliest of (i) the Distribution Date on which
the Certificate Principal Balance of each Class of Certificates has been reduced
to zero, (ii) the final payment or other liquidation of the last Mortgage Loan
in the Trust Fund, and (iii) the optional purchase by the Servicer of the
Mortgage Loans as described below. Notwithstanding the foregoing, in no event
shall the trust created hereby continue beyond the expiration of 21 years from
the death of the last survivor of the descendants of Joseph P. Kennedy, the late
ambassador of the United States to the Court of St. James, living on the date
hereof.

     The Servicer (or an Affiliate) may, at its option, terminate the Mortgage
Loans in the Trust Fund and retire the Certificates on the next succeeding
Distribution Date upon which the current Pool Balance is 10% or less of the Pool
Balance of the Mortgage Loans as of the Cut-off Date (x) by purchasing all of
the outstanding (i) Mortgage Loans in the Trust Fund at a price equal to the sum
of the outstanding Principal Balance of the Mortgage Loans and except to the
extent previously advanced by the Servicer, accrued and unpaid interest thereon
at the weighted average of the Mortgage Interest Rates through the end of the
Collection Period preceding the final Distribution Date plus unreimbursed
Servicing Advances, Advances and any unpaid Servicing Fees allocable to such
Mortgage Loans plus any costs or damages incurred by the Trust Fund in
connection with any violation by such Mortgage Loan of any predatory or abusive
lending laws and (ii) REO Properties in the Trust Fund at a price equal to their
fair market value as determined in good faith by the Servicer, and (y) in
addition to the foregoing, by paying sufficient funds to pay any Swap
Termination Payment in connection with the termination of the Trust Fund
pursuant to this Section 10.01 (the "Termination Price"). Notwithstanding the
foregoing, the Servicer (or an Affiliate) may not exercise its optional purchase
right unless any Reimbursement Amount owed to the Trust pursuant to Section 2.03
hereof has been paid.

     Notwithstanding anything herein to the contrary, only an amount equal to
the Termination Price, reduced by the portion thereof consisting of any funds to
pay any Swap Termination Payment in connection with the termination of the Trust
Fund pursuant to this Section 10.01 (such portion, the "Swap

                                       146

<PAGE>

Optional Termination Payment"), shall be made available for distribution to the
Certificates. The Swap Optional Termination Payment shall be withdrawn by the
Trustee from the Distribution Account and remitted to the Supplemental Interest
Trust for payment to the Swap Counterparty. The Swap Optional Termination
Payment shall not be part of any REMIC and shall not be paid into any account
which is part of any REMIC. In connection with any such purchase pursuant to the
preceding paragraph, the Servicer shall deliver to the Trustee for deposit in
the Distribution Account all amounts then on deposit in the Collection Account
(less amounts permitted to be withdrawn by the Servicer pursuant to Section
3.07), which deposit shall be deemed to have occurred immediately following such
purchase.

     Any such purchase shall be accomplished by delivery to the Trustee for
deposit into the Distribution Account as part of Available Funds on the
Determination Date before such Distribution Date of the Termination Price.

          (b) Notice of any termination, specifying the Distribution Date (which
shall be a date that would otherwise be a Distribution Date) upon which the
Certificateholders may surrender their Certificates to the Trustee for payment
of the final distribution and cancellation, shall be given promptly by the
Trustee upon the Trustee receiving notice of such date from the Servicer, by
letter to the Certificateholders mailed not earlier than the 15th day of the
month preceding the month of such final distribution and not later than the 15th
day of the month of such final distribution specifying (1) the Distribution Date
upon which final distribution of the Certificates will be made upon presentation
and surrender of such Certificates at the office or agency of the Trustee
therein designated, (2) the amount of any such final distribution and (3) that
the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Certificates at the office or agency of the Trustee therein specified.

          (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Section 10.02.

          (d) In the event that all Certificateholders shall not surrender their
Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Servicer (if the Servicer has
exercised its right to purchase the Mortgage Loans) or the Trustee (in any other
case) 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 nine months after the second notice all the
Certificates shall not have been surrendered for cancellation, the Class R
Certificateholders shall be entitled to all unclaimed funds and other assets
which remain subject hereto and the Trustee upon transfer of such funds shall be
discharged of any responsibility for such funds, and such Certificateholders
shall look to the Class R Certificateholders for payment.

     Section 10.02 Additional Termination Requirements.

          (a) In the event that the Servicer exercises its purchase option as
provided in Section 10.01, the Trust shall be terminated in accordance with the
following additional requirements, unless the Trustee shall have been furnished
with an Opinion of Counsel to the effect that the failure of the Trust to comply
with the requirements of this Section will not (i) result in the imposition of
taxes on "prohibited

                                       147

<PAGE>

transactions" of the Trust as defined in Section 860F of the Code or (ii) cause
any REMIC constituting part of the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates are outstanding:

               (i) The Trustee shall designate a date within 90 days prior to
the final Distribution Date as the date of adoption of plans of complete
liquidation delivered to it by the Servicer of each of the remaining REMICs
included in the Trust Fund and shall specify such date in the final federal
income tax return of each REMIC;

               (ii) After the date of adoption of such plans of complete
liquidation and at or prior to the final Distribution Date, the Trustee shall
sell all of the assets of the Trust to the Servicer for cash; and

               (iii) At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be distributed
or credited in the following order of priority (A) (i) to the Holders of each of
the Class A Certificates, pro rata and (ii) to the Class M-1, Class M-2, Class
M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2, Class B-3, Class B-4
and Class B-5 Certificates, the related Certificate Principal Balance, as
applicable, plus one month's interest thereon at the applicable Pass-Through
Rate, (B) (i) any Net WAC Carryover Amounts not previously distributed and (ii)
to the Class CE-1 Certificates, the amount of any remaining Monthly Excess
Cashflow Amounts not previously distributed thereon, (C) to the remaining REMIC
Regular Interests the amounts allocable thereto pursuant to Section 9.01 and (D)
to the Class R Certificateholders, all cash on hand in respect of the related
REMIC or REMICs after such payment (other than cash retained to meet claims) and
the Trust shall terminate at such time.

          (b) By their acceptance of Certificates, the Holders thereof hereby
agree to appoint the Trustee as their attorney in fact to: (i) designate such
date of adoption of plans of complete liquidation and (ii) to take such other
action in connection therewith as may be reasonably required to carry out such
plans of complete liquidation all in accordance with the terms hereof.

     In addition, this Agreement may be amended from time to time by the Seller,
the Depositor, the Servicer and the Trustee, with the consent of the Majority
Certificateholders 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 Holders of Certificates; provided,
however, that no such amendment or waiver shall (x) reduce in any manner the
amount of, or delay the timing of, payments on the Certificates which are
required to be made on any Certificate without the consent of the Holder of such
Certificate, (y) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (x) above, without the consent of the Holders of Certificates of such
Class evidencing at least a 66 2/3% Percentage Interest in such Class, or (z)
reduce the percentage of Voting Rights required by clause (y) above without the
consent of the Holders of all Certificates of such Class then outstanding. Upon
approval of an amendment, a copy of such amendment shall be sent to the Rating
Agencies.

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

     The Trustee shall not enter into any amendment to this Agreement unless (i)
it receives an Officer's Certificate from the Depositor indicating that such
amendment will not have a materially adverse effect on the Swap Counterparty or
(ii) it obtains the written consent of the Swap Counterparty.

     Notwithstanding any provision of this Agreement to the contrary, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, delivered by (and at the expense of)
the Person seeking such Amendment, to the effect that such amendment is
permitted hereunder and will not result in the imposition of a tax on any REMIC
constituting part of the Trust Fund pursuant to the REMIC Provisions or cause
any REMIC constituting part of the Trust to fail to qualify as a REMIC at any
time that any Certificates are outstanding and that the amendment is being made
in accordance with the terms hereof.

     Promptly after the execution of any such amendment the Trustee shall
furnish, at the expense of the Person that requested the amendment if such
Person is the Seller or the Servicer (but in no event at the expense of the
Trustee), otherwise at the expense of the Trust, a copy of such amendment and
the Opinion of Counsel referred to in the immediately preceding paragraph to the
Servicer and each Rating Agency.

     It shall not be necessary for the consent of Certificateholders under this
Section 11.01 to approve the particular form of any proposed amendment; instead
it shall be sufficient if such consent shall approve the substance thereof. 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.

     Notwithstanding anything to the contrary in this Section 11.01, the
Trustee, the Seller and the Servicer shall reasonably cooperate with the
Depositor and its counsel to enter into such amendments or modifications to the
Agreement as may be necessary to comply with Regulation AB and any
interpretation thereof by the Securities and Exchange Commission.
Notwithstanding the foregoing, none of the Seller, the Servicer and the Trustee
shall be obligated to enter into any amendment pursuant to this paragraph that
adversely affects its obligations and immunities under this Agreement.

<PAGE>

     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
Servicer at the expense of the Trust, but only upon direction of
Certificateholders, accompanied by an Opinion of Counsel to the effect that such
recordation materially and beneficially affects 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

same instrument.

     Section 11.03 Limitation on Rights of Certificateholders.

     The death or incapacity of any Certificateholder shall not (i) operate to
terminate this Agreement or the Trust, (ii) 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, or (iii)
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

     Except as expressly provided for herein, no Certificateholder 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 constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder 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.

     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 or under or with respect to this Agreement, unless such Holder previously
shall have given to the Trustee a written notice of default and of the
continuance thereof, as herein provided, and unless also the Holders of
Certificates entitled to at least 25% of the Voting Rights 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, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 15 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. It is understood
and intended, and expressly covenanted by each Certificateholder with every
other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatever by virtue of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, which priority or
preference is not otherwise provided for herein, or to enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all Certificateholders. For the protection and enforcement
of the provisions of this Section 11.03 each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

brought in any such court has been brought in any inconvenient forum and further
irrevocably waives the right to object, with respect to such claim, suit, action

jurisdiction over such party, provided that service of process has been made by
any lawful means.

Depositor, the Servicer, the Trustee, the Sponsor and the rights of the

provided in the Agreement, duly endorsed by, or accompanied by an assignment in
the form below or other written instrument of transfer in form satisfactory to
the Trustee and the Certificate Registrar duly executed by, the Holder hereof or

Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

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

     The Depositor, the Servicer, the Trustee, any Paying Agent and the
Certificate Registrar and any agent of the Depositor, the Servicer, the Trustee,
any Paying Agent or the Certificate Registrar may treat the Person in whose name
this Certificate is registered as the owner hereof for all purposes, and none of
the Depositor, the Servicer, the Trustee, the Certificate Registrar, any Paying
Agent nor any such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust Fund created thereby
shall terminate upon payment to the Certificateholders of all amounts held by or
on behalf of the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from the Trust Fund of all
Mortgage Loans and all property acquired in respect of such Mortgage Loans. The
Agreement permits, but does not require, the party designated in the Agreement
to purchase from the Trust Fund all Mortgage Loans and all property acquired in
respect of any Mortgage Loan at a price determined as provided in the Agreement.
The recitals contained herein shall be taken as statements of the Depositor and
neither the Trustee nor the Servicer assumes responsibility for their
correctness.

Certificateholder's prospective transferee shall each execute a representation
letter in the form described by the Agreement certifying to the Certificate
Registrar the facts surrounding the transfer, and (ii) unless such transfer is
made in reliance upon Rule 144A under the 1933 Act, the Depositor and the
Certificate Registrar may require an Opinion of Counsel satisfactory to them
that such transfer may be made without such registration or qualification, which
Opinion of Counsel shall not be an expense of the Depositor, the Trustee or the
Certificate Registrar, in their respective capacities as such. None of the
Depositor, the Certificate Registrar or the Trustee is obligated to register or
qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any such Certificateholder desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor, the Certificate Registrar and the Servicer against any liability that
may result if the transfer is not so exempt or is not made in accordance with
such federal and state laws. Each Person who acquires this Certificate or an
interest therein shall be deemed to have made the representations required by
the representation letter referred to in this paragraph, unless such Person
shall have provided such representation letter referred to in this paragraph to
the Certificate Registrar.

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

     No transfer of this Certificate shall be made unless that transfer is made
pursuant to an effective registration statement under the 1933 Act and effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that a transfer is to be made without registration or qualification
(i) the Certificateholder desiring to effect the transfer and such
Certificateholder's prospective transferee shall each execute a representation
letter in the form described by the Agreement certifying to the Certificate
Registrar the facts surrounding the transfer, and (ii) unless such transfer is
made in reliance upon Rule 144A under the 1933 Act, the Depositor and the
Certificate Registrar may require an Opinion of Counsel satisfactory to them
that such transfer may be made without such registration or qualification, which
Opinion of Counsel shall not be an expense of the Depositor, the Trustee or the
Certificate Registrar, in their respective capacities as such. None of the
Depositor, the Certificate Registrar or the Trustee is obligated to register or
qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any such Certificateholder desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor, the Certificate Registrar and the Servicer against any liability that
may result if the transfer is not so exempt or is not made in accordance with
such federal and state laws.

     No transfer of a Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA and Section 4975 of the Code ("Plans") or any person who is
directly or indirectly purchasing the Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan.

     The Holder of this Certificate, by its acceptance hereof, shall be deemed
for all purposes to have consented to the provisions of Section 5.02 of the
Agreement and to any amendment of the Agreement deemed necessary by counsel of
the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause any REMIC
provided for in the Trust Agreement to cease to qualify as a REMIC or cause the
imposition of a tax upon the Trust.

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

     The Depositor, the Servicer, the Trustee, any Paying Agent and the
Certificate Registrar and any agent of the Depositor, the Servicer, the Trustee,
any Paying Agent or the Certificate Registrar may treat the Person in whose name
this Certificate is registered as the owner hereof for all purposes, and none of
the Depositor, the Servicer, the Trustee, the Certificate Registrar, any Paying
Agent nor any such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust Fund created thereby
shall terminate upon payment to the Certificateholders of all amounts held by or
on behalf of the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from the Trust Fund of all
Mortgage Loans and all property acquired in respect of such Mortgage Loans. The
Agreement permits, but does not require, the party designated in the Agreement
to purchase from the Trust Fund all Mortgage Loans and all property acquired in
respect of any Mortgage Loan at a price determined as provided in the Agreement.
The exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Principal Balance of
the Mortgage Loans at the time of purchase being 10% or less of the Cut-off Date
Aggregate Principal Balance.

     The recitals contained herein shall be taken as statements of the Depositor
and neither the Trustee nor the Servicer assumes responsibility for their

     Unless the certificate of authentication hereon has been executed by the
Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

notified the Certificate Registrar in writing at least five Business Days prior
to the Record Date immediately prior to such Distribution Date and is the
registered owner of Class R-X Certificates, or by check mailed by first class
mail to the address of the Person entitled thereto, as such name and address
shall appear on the Certificate Register, provided that the Certificate
Registrar may deduct a reasonable wire transfer fee from any payment made by
wire transfer. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
office or agency appointed by the Trustee for that purpose as provided in the
Agreement.

     This Certificate is one of a duly authorized issue of Certificates
designated as C-Bass Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and representing
the Percentage Interest specified on the face hereof.

     The Class R-X Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee, the Sponsor and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the
Servicer, the Sponsor and the Trustee with the consent of the Holders of
Certificates entitled to the Voting Rights identified in the Agreement. 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 exchange herefor 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 registerable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by, the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

     The Certificates are issuable in fully registered form only without coupons
in Classes and denominations representing Percentage Interests specified in the
Agreement. As provided in the Agreement and subject to certain limitations
therein set forth, Certificates are exchangeable for new Certificates of the
same Class in authorized denominations evidencing the same aggregate Percentage
Interest, as requested by the Holder surrendering the same.

     No transfer of this Certificate shall be made unless that transfer is made
pursuant to an effective registration statement under the 1933 Act and effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that a transfer is to be made without registration or qualification
(i) the Certificateholder desiring to effect the transfer and such
Certificateholder's prospective transferee shall each execute a representation
letter in the form described by the Agreement certifying to the Certificate
Registrar the facts surrounding the transfer, and (ii) unless such transfer is
made in reliance upon Rule 144A under the 1933 Act, the Depositor and the
Certificate Registrar may require an Opinion of Counsel satisfactory to them
that such transfer may be made without such registration or qualification, which
Opinion of Counsel shall not be an expense of the Depositor, the Trustee or the
Certificate Registrar, in their respective capacities as such. None of the
Depositor, the Certificate Registrar or the Trustee is obligated to register or
qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any such Certificateholder desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor, the Certificate Registrar and the Servicer against any liability that
may result if the transfer is not so exempt or is not made in accordance with
such federal and state laws.

     No transfer of a Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA and Section 4975 of the Code ("Plans") or any person who is
directly or indirectly purchasing the Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan.

     The Holder of this Certificate, by its acceptance hereof, shall be deemed
for all purposes to have consented to the provisions of Section 5.02 of the
Agreement and to any amendment of the Agreement deemed necessary by counsel of
the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause any REMIC
provided for in the Trust Agreement to cease to qualify as a REMIC or cause the
imposition of a tax upon the Trust.

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

     The Depositor, the Servicer, the Trustee, any Paying Agent and the
Certificate Registrar and any agent of the Depositor, the Servicer, the Trustee,
any Paying Agent or the Certificate Registrar may treat the Person in whose name
this Certificate is registered as the owner hereof for all purposes, and none of
the Depositor, the Servicer, the Trustee, the Certificate Registrar, any Paying
Agent nor any such agent shall be affected by notice to the contrary.

evidencing an ownership interest in distributions allocable to the Class P
Certificates with respect to a pool of conventional, sub-prime mortgage loans
formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

This certifies that [OWNER] is the registered owner of the ownership interest
(the "Ownership Interest") evidenced by this Certificate (obtained by dividing
the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class P Certificates) in certain distributions with
respect to a pool of conventional, sub-prime mortgage loans (the "Mortgage
Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc. (hereinafter
called the "Depositor"), and certain other property held in trust for the
benefit of Certificateholders (collectively, the "Trust Fund"). The Mortgage
Loans are serviced by Litton Loan Servicing LP (the "Servicer") and are secured
by first or second-lien mortgages on the Mortgaged Properties. The Trust Fund
was created pursuant to a pooling and servicing agreement (the "Agreement"),
dated as of April 1, 2007, among the Depositor, the Servicer, Credit-Based Asset
Servicing and Securitization and LaSalle Bank National Association ("LB"), as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement.

This Certificate is one of a duly authorized issue of Certificates, designated
as C-Bass Mortgage Loan Asset Backed Certificates, Series 2007-CB4, Class P (the
"Class P Certificates") and 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 the acceptance hereof assents and by which
Agreement such Holder is bound.

The Class A Certificates, the Class M Certificates, the Class B Certificates,
the Class P Certificates, the Class CE-1 Certificates, Class CE-2 Certificates,
Class R Certificates, Class R-X Certificates are collectively referred to herein
as the "Certificates."

Pursuant to the terms of the Agreement, the Trustee will distribute from funds
in the Certificate Account the amounts described in the Agreement on the 25th
day of each month or, if such 25th day is not a Business Day, the Business Day
immediately following (the "Distribution Date"), commencing in May 2007. Such
distributions will be made to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
preceding the month in which such payment is made, if such last day is not a
Business Day, the Business Day immediately preceding such last day.

Distributions on this Certificate will be made either by check mailed to the
address of the person entitled to distributions as it appears on the Certificate
Register or, in the case of any certificateholder that has so notified the
Trustee in writing in accordance with the Agreement, by wire transfer in
immediately available funds to the account of such certificateholder at a bank
or other depository institution having appropriate wire transfer facilities;
provided, however, that the final distribution in retirement of the certificates
will be made only upon presentation and surrender of this Certificate at the
office of the Trustee or such other address designated in writing by the
Trustee. On each Distribution Date, a holder of this Certificate will receive
such

                                     C-3-3

<PAGE>

holder's Percentage Interest of the amounts required to be distributed with
respect to the applicable Class of Certificates.

The Trustee will maintain or cause to be maintained a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Trustee
will provide for the registration of Certificates and of transfers and exchanges
of Certificates. Upon surrender for registration of transfer of any Certificate
at any office or agency of the Trustee, or, if an Authenticating Agent has been
appointed under the Agreement, the Authenticating Agent, maintained for such
purpose, the Trustee, will, subject to the limitations set forth in the
Agreement, authenticate and deliver, in the name of the designated transferee or
transferees, a Certificate of a like class and dated the date of authentication
by the Authenticating Agent. Notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Trustee, of the
pendency of such distribution and only upon presentation and surrender of this
Certificate at the office or agency appointed by the Trustee, for that purpose
and specified in such notice of final distribution.

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

Unless the certificate of authentication has been executed by the Authenticating
Agent, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

This Certificate is one of a duly authorized issue of Certificates, designated
as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2007-CB4, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates,
Class CE-1 Certificates, Class CE-2 Certificates, Class R Certificates and Class
R-X Certificate, each evidencing an interest in certain distributions with
respect to a pool of conventional, sub-prime Mortgage Loans formed and sold by
the Depositor and certain other property conveyed by the Depositor to the
Trustee.

The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders 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.

No service charge will be made to the Holder for any transfer or exchange of the
Certificate, but the Trustee may require payment of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

<PAGE>

The Agreement may be amended from time to time by the Depositor, the Servicer
and the Trustee, without the consent of any of the Certificateholders, to cure
any ambiguity, to correct or supplement any provisions therein which may be
inconsistent with the other provisions therein, to ensure continuing treatment
of each REMIC included in the Trust Fund as a REMIC, or to make any other
provisions with respect to matters or questions arising under the Agreement
which are not materially inconsistent with the provisions of the Agreement,
provided that such action does not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any Certificateholder.

The Agreement may also be amended from time to time by the Depositor, the
Servicer the Trustee, with the consent of the Holders of Certificates evidencing
in the aggregate not less than 66 2/3% of the Percentage Interests of each Class
of Certificates affected thereby, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of the Agreement or
of modifying in any manner the rights of the Holders of Certificates of such
Class; provided, however, that no such amendment may (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) adversely affect in any material respect the
interests of the Holders of any Class of Certificates in a manner other than as
described in clause (i), without the consent of the Holders of Certificates of
such Class evidencing 66 2/3% or more of the Voting Rights of such Class or
(iii) change the percentage specified in clause (ii) of the third paragraph of
Section 10.01 of the Agreement, without the consent of the Holders of all
Certificates of such Class then outstanding.

For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC"). The REMIC Regular
Interests will represent "regular interests" in one of the REMICs included in
the Trust Fund. The Class R Certificate will represent the sole class of
"residual interest" in each of the REMICs.

The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created hereby continue beyond the earlier of (i) 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 hereof and (ii) the Latest Possible Maturity Date.

evidencing an ownership interest in distributions allocable to the Class
CE-[1][2] Certificates with respect to a pool of conventional, sub-prime
mortgage loans formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

This certifies that Merrill Lynch, Pierce, Fenner & Smith Incorporated, is the
registered owner of the ownership interest (the "Ownership Interest") evidenced
by this Certificate (obtained by dividing the Original Denomination of this
Certificate by the aggregate Initial Certificate Balance of all Class CE-[1][2]
Certificates) in certain distributions with respect to a pool of conventional,
sub-prime mortgage loans (the "Mortgage Loans") formed and sold by Merrill Lynch
Mortgage Investors, Inc. (hereinafter called the "Depositor"), and certain other
property held in trust for the benefit of Certificateholders (collectively, the
"Trust Fund"). The Mortgage Loans are serviced by Litton Loan Servicing LLP (the
"Servicer") and are secured by first or second-lien mortgages on the Mortgaged
Properties. The Trust Fund was created pursuant to a pooling and servicing
agreement (the "Agreement"), dated as of April 1, 2007, among the Depositor, the
Servicer, Credit-Based Asset Servicing and Securitization LLC and LaSalle Bank
National Association ("LB"), as trustee (the "Trustee"), a summary of certain of
the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in
the Agreement.

This Certificate is one of a duly authorized issue of Certificates, designated
as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2007-CB4, Class CE-[1][2] (the "Class CE-[1][2]
Certificates") and 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 the acceptance hereof assents and by which Agreement such Holder is
bound.

The Class A Certificates, the Class M Certificates, the Class B Certificates,
the Class P Certificates, the Class CE-1 Certificates, Class CE-2 Certificates,
the Class R Certificates and the Class R-X Certificates are collectively
referred to herein as the "Certificates."

Pursuant to the terms of the Agreement, the Trustee will distribute from funds
in the Certificate Account the amounts described in the Agreement on the 25th
day of each month or, if such 25th day is not a Business Day, the Business Day
immediately following (the "Distribution Date"), commencing in May 2007. Such
distributions will be made to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
preceding the month in which such payment is made, if such last day is not a
Business Day, the Business Day immediately preceding such last day.

Distributions on this Certificate will be made either by check mailed to the
address of the person entitled to distributions as it appears on the Certificate
Register or, in the case of any certificateholder that has so notified the
Trustee in writing in accordance with the Agreement, by wire transfer in
immediately available funds to the account of such certificateholder at a bank
or other depository institution having appropriate wire transfer facilities;
provided, however, that the final distribution in retirement of the certificates
will be made only upon presentation and surrender of this Certificate at the
office of the Trustee or such other address designated in

                                     C-4-3

<PAGE>

writing by the Trustee. On each Distribution Date, a holder of this Certificate
will receive such holder's Percentage Interest of the amounts required to be
distributed with respect to the applicable Class of Certificates.

The Trustee will maintain or cause to be maintained a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Trustee
will provide for the registration of Certificates and of transfers and exchanges
of Certificates. Upon surrender for registration of transfer of any Certificate
at any office or agency of the Trustee, or, if an Authenticating Agent has been
appointed under the Agreement, the Authenticating Agent, maintained for such
purpose, the Trustee, will, subject to the limitations set forth in the
Agreement, authenticate and deliver, in the name of the designated transferee or
transferees, a Certificate of a like class and dated the date of authentication
by the Authenticating Agent. Notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Trustee, of the
pendency of such distribution and only upon presentation and surrender of this
Certificate at the office or agency appointed by the Trustee, for that purpose
and specified in such notice of final distribution.

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

Unless the certificate of authentication has been executed by the Authenticating
Agent, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

This Certificate is one of a duly authorized issue of Certificates, designated
as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2007-CB4, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates,
Class CE-[1][2] Certificates, Class CE-2 Certificates, Class R Certificates, and
Class R-X Certificates each evidencing an interest in certain distributions with
respect to a pool of conventional, sub-prime Mortgage Loans formed and sold by
the Depositor and certain other property conveyed by the Depositor to the
Trustee.

Following the initial issuance of the Certificates, the principal balance of
this Certificate will be different from the Original Denomination shown above.
Anyone acquiring this Certificate may ascertain its current principal balance by
inquiry of the Trustee.

The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders 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.

No service charge will be made to the Holder for any transfer or exchange of the
Certificate, but the Trustee may require payment of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat

                                     C-4-4

<PAGE>

the person in whose name any Certificate is registered as the owner of such
Certificate and the Percentage Interest in the Trust Fund evidenced thereby for
the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

The Agreement may be amended from time to time by the Depositor, the Servicer
and the Trustee, without the consent of any of the Certificateholders, to cure
any ambiguity, to correct or supplement any provisions therein which may be
inconsistent with the other provisions therein, to ensure continuing treatment
of each REMIC included in the Trust Fund as a REMIC, or to make any other
provisions with respect to matters or questions arising under the Agreement
which are not materially inconsistent with the provisions of the Agreement,
provided that such action does not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any Certificateholder.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee, the Sponsor and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the
Servicer, the Sponsor and the Trustee with the consent of the Holders of
Certificates entitled to the Voting Rights identified in the Agreement. 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 exchange herefor 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.

For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC"). The REMIC Regular
Interests will represent "regular interests" in one of the REMICs included in
the Trust Fund. The Class R Certificate will represent the sole class of
"residual interest" in each of the REMICs.

The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created hereby continue beyond the earlier of (i) 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 hereof and (ii) the Latest Possible Maturity Date.

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

                 FORM OF RESIDUAL CERTIFICATE TRANSFER AFFIDAVIT

         C-BASS MORTGAGE LOAN ASSET-BACKED CERTIFICATES, SERIES 2007-CB4

STATE OF ______________________)

_______________________________) ss.:

COUNTY OF _____________________)

     The undersigned, being first duly sworn, deposes and says as follows:

     1. The undersigned is [an officer of] ______________, the proposed
Transferee of an Ownership Interest in a [Class R and/or Class R-X Certificates]
(the "Residual Certificate") issued pursuant to the Pooling and Servicing
Agreement, (the "Agreement"), relating to the above-referenced Certificates,
among Merrill Lynch Mortgage Investors, Inc., as depositor, Credit-Based Asset
Servicing and Securitization LLC, as sponsor, Litton Loan Servicing LP, as
servicer, and LaSalle Bank National Association, as trustee (the "Trustee").
Capitalized terms used, but not defined herein shall have the meanings ascribed
to such terms in the Agreement. The Transferee has authorized the undersigned to
make this affidavit on behalf of the Transferee.

     2. The Transferee is, as of the date hereof, and will be, as of the date of
the transfer, a Permitted Transferee. The Transferee is acquiring the Residual
Certificate either (i) for its own account or (ii) as nominee, trustee or agent
for another Person who is a Permitted Transferee and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

     3. The Transferee has been advised of, and understands that (i) a tax will
be imposed on Transfers of the Residual Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is a Permitted Transferee and, at the time of
transfer, such Person does not have actual knowledge that the affidavit is
false.

     4. The Transferee has been advised of, and understands that a tax will be
imposed on a "pass-through entity" holding the Certificate if at any time during
the taxable year of the pass-through entity a Person that is not a Permitted
Transferee is the record Holder of an interest in such entity. The Transferee
understands that, other than in the case of an "electing large partnership"
under Section 775 of the Code, such tax will not be imposed for any period with
respect to which the record Holder furnishes to the pass-through entity an
affidavit that such record Holder is a Permitted Transferee and the pass-through
entity does not have actual knowledge that such affidavit is false. (For this
purpose, a "pass-through entity" includes a regulated investment company, a real
estate investment trust or common trust fund, a partnership, trust or estate,
and certain cooperatives and, except as may be provided in Treasury Regulations,
persons holding interests in pass-through entities as a nominee for another
Person.)

     5. The Transferee has reviewed the provisions of Section 5.02 of the
Agreement and understands the legal consequences of the acquisition of the
Residual Certificate including, without limitation, the restrictions on
subsequent Transfers and the provisions regarding voiding the transfer and
mandatory sales. The Transferee expressly agrees to be bound by and to abide by
the provisions of Section 5.02 of the Agreement and the restrictions noted on
the face of the Certificate. The Transferee

                                      K-1

<PAGE>

understands and agrees that any breach of any of the representations included
herein shall render the transfer to the Transferee contemplated hereby null and
void.

     6. The Transferee agrees to require a transfer affidavit in the form of
this Affidavit from any Person to whom the Transferee attempts to transfer the
Residual Certificate, and in connection with any transfer by a Person for whom
the Transferee is acting as nominee, trustee or agent, and the Transferee will
not transfer the Residual Certificate or cause the Residual Certificate to be
transferred to any Person that the Transferee knows is not a Permitted
Transferee.

     7. The Transferee historically has paid its debts as they have become due.

     8. The Transferee does not have the intention to impede the assessment or
collection of any tax legally required to be paid with respect to the Residual
Certificate.

     9. The taxpayer identification number of the Transferee's nominee is
___________.

     10. The Transferee is a U.S. Person as defined in Code Section 7701(a)(30).

     11. The Transferee is aware that the Residual Certificate may be a
"noneconomic residual interest" within the meaning of Treasury Regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

     12. The Transferee will not cause income from the Residual Certificate to
be attributable to a foreign permanent establishment or fixed base, within the
meaning of an applicable income tax treaty, of the Transferee or any other
person.

     13. If the Transferee is purchasing the Residual Certificate in a transfer
intended to meet the safe harbor provisions of Treasury Regulations Sections
1.860E-1(c), the Transferee has executed and attached Attachment A hereto.

     14. The Transferee is not an employee benefit plan or arrangement subject
to Title I of ERISA, a plan subject to Section 4975 of the Code or a plan
subject to any state, local or other federal law substantively similar to the
foregoing provisions of ERISA or the Code (collectively, a "Plan"), and is not
directly or indirectly acquiring this Certificate for, on behalf of or with any
assets of any such Plan.

[ ]  The transfer of the Residual Certificate complies with U.S. Treasury

          from Residual Certificate will only be taxed in the United States;

     (ii) at the time of the transfer, and at the close of the Transferee's two
          fiscal years preceding the year of the transfer, the Transferee had
          gross assets for financial reporting purposes (excluding any
          obligation of a person related to the Transferee within the meaning of
          U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of
          $100 million and net assets in excess of $10 million;

          "eligible corporation," as defined in U.S. Treasury Regulations
          Section 1.860E-1(c)(6)(i), in a transaction that satisfies the

          1.860E-1(c)(5) of the U.S. Treasury Regulations;

          (including, but not limited to, borrowing and investment rates,
          prepayment and loss assumptions, expense and reinvestment assumptions,
          tax rates and other factors specific to the Transferee) that it has
          determined in good faith; and

          Transferee, the Transferee will require its transferee to complete a
          representation in the form of this Attachment A as a condition of such

               an agreement between Party B and such Reference Market-maker to
               enter into a Replacement Transaction, and (3) made on the basis
               that Unpaid Amounts in respect of the Terminated Transaction or
               group of Transactions are to be excluded but, without limitation,
               any payment or delivery that would, but for the relevant Early
               Termination Date, have been required (assuming satisfaction of
               each applicable condition precedent) after that Early Termination
               Date is to be included.

          (B)  The definition of Settlement Amount shall be deleted in its
               entirety and replaced with the following:

               "SETTLEMENT AMOUNT" means, with respect to any Early Termination
               Date, an amount (as determined by Party B) equal to:

               (a)  If a Market Quotation for the relevant Terminated
                    Transaction or group of Terminated Transactions is accepted
                    by Party B so as to become legally binding on or before the
                    day falling ten Local Business Days after the day on which
                    the Early Termination Date is designated, or such later day
                    as Party B may specify in writing to Party A, but in either
                    case no later than one Local Business Day prior to the Early
                    Termination Date (such day, the "Latest Settlement Amount
                    Determination Day"), the Termination Currency Equivalent of
                    the amount (whether positive or negative) of such Market
                    Quotation;

               (b)  If, on the Latest Settlement Amount Determination Day, no
                    Market Quotation for the relevant Terminated Transaction or
                    group of Terminated Transactions has been accepted by Party
                    B so as to become legally binding and one or more Market
                    Quotations from Approved Replacements have been made and
                    remain capable of becoming legally binding upon acceptance,
                    the Settlement Amount shall equal the Termination Currency
                    Equivalent of the amount (whether positive or negative) of
                    the lowest of such Market Quotations (for the avoidance of
                    doubt, the lowest of such Market Quotations shall be the
                    lowest Market Quotation of such Market Quotations expressed
                    as a positive number or, if any of such Market Quotations is
                    expressed as a negative number, the Market Quotation
                    expressed as a negative number with the largest absolute
                    value); or

               (c)  If, on the Latest Settlement Amount Determination Day, no
                    Market Quotation for the relevant Terminated Transaction or
                    group of Terminated Transactions is accepted by Party B so
                    as to become legally binding and no Market Quotation from an
                    Approved Replacement remains capable of becoming legally
                    binding

                                      N-1-5

<PAGE>

                    upon acceptance, the Settlement Amount shall equal Party B's
                    Loss (whether positive or negative and without reference to
                    any Unpaid Amounts) for the relevant Terminated Transaction
                    or group of Terminated Transactions.

          (C)  If Party B requests Party A in writing to obtain Market
               Quotations, Party A shall use its reasonable efforts to do so
               before the Latest Settlement Amount Determination Day.

          (D)  If the Settlement Amount is a negative number, Section 6(e)(i)(3)
               shall be deleted in its entirety and replaced with the following:

               "(3) Second Method and Market Quotation. If the Second Method and
               Market Quotation apply, (I) Party B shall pay to Party A an
               amount equal to the absolute value of the Settlement Amount in
               respect of the Terminated Transactions, (II) Party B shall pay to
               Party A the Termination Currency Equivalent of the Unpaid Amounts
               owing to Party A and (III) Party A shall pay to Party B the
               Termination Currency Equivalent of the Unpaid Amounts owing to
               Party B; provided, however, that (x) the amounts payable under
               the immediately preceding clauses (II) and (III) shall be subject
               to netting in accordance with Section 2(c) of this Agreement and
               (y) notwithstanding any other provision of this Agreement, any
               amount payable by Party A under the immediately preceding clause
               (III) shall not be netted-off against any amount payable by Party
               B under the immediately preceding clause (I)."

          (E)  At any time on or before the Latest Settlement Amount
               Determination Day at which two or more Market Quotations from
               Approved Replacements remain capable of becoming legally binding
               upon acceptance, Party B shall be entitled to accept only the
               lowest of such Market Quotations (for the avoidance of doubt, the
               lowest of such Market Quotations shall be the lowest Market
               Quotation of such Market Quotations expressed as a positive
               number or, if any of such Market Quotations is expressed as a
               negative number, the Market Quotation expressed as a negative

          for this Additional Termination Event in respect of all Affected
          Transactions; (C) Section 2(a)(iii)(2) shall not be applicable to any

          Transactions resulting from this Additional Termination Event will be
          required to be made through and including the Early Termination Date
          designated as a result of this Additional Termination Event; provided,
          for the avoidance of doubt, that any such payments or deliveries that

          treated as Unpaid Amounts in determining the amount payable in respect
          of such Early Termination Date; (D) notwithstanding anything to the
          contrary in Section 6(d)(i), (I) if, no later than 4:00 pm New York

          Distribution Date specified in the Optional Termination Notice, the
          Trustee requests the amount of the Estimated Swap Termination Payment,
          Party A shall provide to the Trustee in writing (which may be done in

          format) the amount payable by either Party B or Party A in respect of
          the related Early Termination Date in connection with this Additional
          Termination Event; provided, however, that the amount payable by Party
          B, if any, in respect of the related Early Termination Date shall be

          Payment; and (E) notwithstanding anything to the contrary in this

          Event will be payable on the final Distribution Date specified in the
          Optional Termination Notice and any amount due from Party A to Party B
          in respect of this Additional Termination Event will be payable one
          Business Day prior to the final Distribution Date specified in the
          Optional Termination Notice.

          The Trustee shall be an express third party beneficiary of this
          Agreement as if a party hereto to the extent of the Trustee's rights
          specified herein.

     (v)  PROVISION OF INFORMATION REQUIRED BY REGULATION AB. An Additional
          Termination Event shall occur if Party A fails to satisfy its
          obligations under Section 2 of that certain Item 1115 Agreement dated
          as of April 27, 2007, among Credit-Based Asset Servicing and
          Securitization LLC ("Sponsor"), Merrill Lynch Mortgage Investors, Inc.
          ("Depositor") and The Bank of New York (the "Derivative Provider").For
          all purposes of this Agreement, Party A shall be the sole Affected
          Party with respect to the occurrence of an Additional Termination
          Event described in this Part 5(c)(v).

(d)  REQUIRED RATINGS DOWNGRADE EVENT. In the event that no Relevant Entity has
     credit ratings at least equal to the Required Ratings Threshold (such
     event, a "REQUIRED RATINGS DOWNGRADE EVENT"), then Party A shall, as soon
     as reasonably practicable and so long as a Required Ratings Downgrade Event
     is in effect, at its own expense, using commercially reasonable efforts,
     procure either (A) a Permitted Transfer or (B) an Eligible Guarantee from
     an Eligible Guarantor.

(e)  [Reserved]

(f)  TRANSFERS.

     (i)  Section 7 is hereby amended to read in its entirety as follows:

          "Except with respect to any Permitted Transfer pursuant to Section
          6(b)(ii), Part 5(d), the Item 1115 Agreement, or the succeeding
          sentence, neither Party A nor Party B is permitted to assign, novate
          or transfer (whether by way of security or otherwise) as a whole or in
          part any of its rights, obligations or interests under the Agreement
          or any Transaction unless (a) the prior written consent of the other
          party is obtained, and (b) the Rating Agency Condition has been
          satisfied with respect to S&P and Fitch. At any time at which no
          Relevant Entity has credit ratings at least equal to the Approved
          Ratings Threshold, Party A may make a Permitted Transfer."

     (ii) If an Eligible Replacement has made a Firm Offer (which remains an
          offer that will become legally binding upon acceptance by Party B) to
          be the transferee pursuant to a Permitted Transfer, Party B shall, at
          Party A's written request and at Party A's expense, execute such
          documentation provided to it as reasonably deemed necessary by Party
          A.

(g)  NON-RECOURSE. Party A acknowledges and agrees that, notwithstanding any
     provision in this Agreement to the contrary, the obligations of Party B
     hereunder are limited recourse obligations of Party B, payable solely from
     the Supplemental Interest Trust and the proceeds thereof, in accordance
     with the priority of payments and other terms of the Pooling and Servicing
     Agreement and that Party A will not have any recourse to any of the
     directors, officers, agents, employees, shareholders or affiliates of the
     Party B with respect to any claims, losses, damages, liabilities,
     indemnities or other obligations in connection with any transactions
     contemplated hereby. In the event that the Supplemental Interest Trust and
     the proceeds thereof, should be insufficient to satisfy all claims
     outstanding and following the realization of the account held by the
     Supplemental Interest Trust and the proceeds thereof, any claims against or
     obligations of Party B under the ISDA Master Agreement or any other
     confirmation thereunder still outstanding shall be extinguished and
     thereafter not revive. The Supplemental Interest Trust Trustee shall not
     have liability for any failure or delay in making a payment hereunder to
     Party A due to any failure or delay in receiving amounts in the account
     held by the Supplemental Interest Trust from the Trust created pursuant to
     the Pooling and Servicing Agreement. This provision will survive the
     termination of this Agreement.

(h)  TIMING OF PAYMENTS BY PARTY B UPON EARLY TERMINATION. Notwithstanding
     anything to the contrary in Section 6(d)(ii), to the extent that all or a
     portion (in either case, the "Unfunded Amount") of any amount that is
     calculated as being due in respect of any Early Termination Date under
     Section 6(e) from Party B to Party A will be paid by Party B from amounts
     other than any upfront payment paid to Party B by an Eligible Replacement
     that has entered a Replacement Transaction with Party B, then such Unfunded
     Amount shall be due on the next subsequent Distribution Date following the
     date on which the payment would have been payable as determined in
     accordance with Section 6(d)(ii), and on any subsequent Distribution Dates
     until paid in full (or if such Early Termination Date is the final
     Distribution Date, on such final Distribution Date); provided, however,
     that if the date on which the payment would have been payable as determined
     in accordance with Section 6(d)(ii) is a Distribution Date, such payment
     will be payable on such Distribution Date.

(i)  RATING AGENCY NOTIFICATIONS. Notwithstanding any other provision of this
     Agreement, no Early Termination Date shall be effectively designated
     hereunder by Party B and no transfer of any rights or obligations under
     this Agreement shall be made by either party unless each Swap Rating Agency
     has been given prior written notice of such designation or transfer.

(j)  NO SET-OFF. Except as expressly provided for in Section 2(c), Section 6 or
     Part 1(f)(i)(D) hereof, and notwithstanding any other provision of this
     Agreement or any other existing or future agreement, each party irrevocably
     waives any and all rights it may have to set off, net, recoup or otherwise
     withhold or suspend or condition payment or performance of any obligation
     between it and the other party hereunder against any obligation between it
     and the other party under any other agreements. Section 6(e) shall be
     amended by deleting the following sentence: "The amount, if any, payable in
     respect of an Early Termination Date and determined pursuant to this
     Section will be subject to any Set-off.".

(k)  AMENDMENT. Notwithstanding any provision to the contrary in this Agreement,
     no amendment of either this Agreement or any Transaction under this
     Agreement shall be permitted by either party unless each of the Swap Rating
     Agencies has been provided prior written notice of the same and such
     amendment satisfies the Rating Agency Condition with respect to S&P and
     Fitch.

(l)  NOTICE OF CERTAIN EVENTS OR CIRCUMSTANCES. Each Party agrees, upon learning
     of the occurrence or existence of any event or condition that constitutes
     (or that with the giving of notice or passage of time or both would
     constitute) an Event of Default or Termination Event with respect to such
     party, promptly to give the other Party and to each Swap Rating Agency
     notice of such event or condition; provided that failure to provide notice
     of such event or condition pursuant to this Part 5(l) shall not constitute
     an Event of Default or a Termination Event.

(m)  PROCEEDINGS. No Relevant Entity shall institute against, or cause any other
     person to institute against, or join any other person in instituting
     against Party B, the Supplemental Interest Trust, or the Trust formed
     pursuant to the Pooling and Servicing Agreement, in any bankruptcy,
     reorganization, arrangement, insolvency or liquidation proceedings or other
     proceedings under any federal or state bankruptcy or similar law for a
     period of one year (or, if longer, the applicable preference period) and
     one day following payment in full of the Certificates and any Notes. This
     provision will survive the termination of this Agreement.

(n)  SUPPLEMENTAL INTEREST TRUST TRUSTEE LIABILITY LIMITATIONS. It is expressly
     understood and agreed by the parties hereto that (a) this Agreement is
     executed and delivered by LaSalle Bank National Association, not
     individually or personally but solely as the Supplemental Interest Trust
     Trustee, in the exercise of the powers and authority conferred and vested
     in it under the Pooling and Servicing Agreement, (b) the representations,
     warranties, covenants, undertakings and agreements herein made on the part
     of the Supplemental Interest Trust are made and intended not as personal
     representations, undertakings and agreements by LaSalle Bank National
     Association but are made and intended for the purpose of binding only the
     Supplemental Interest Trust, (c) nothing herein contained shall be
     construed as creating any liability on LaSalle Bank National Association,
     individually or personally, to perform any covenant either expressed or
     implied contained herein, all such liability, if any, being expressly
     waived by the parties who are signatories to this Agreement and by

                                     N-1-14

<PAGE>

     any person claiming by, through or under such parties and (d) under no
     circumstances shall LaSalle Bank National Association be personally liable
     for the payment of any indemnity, indebtedness, fees or expenses of the
     Supplemental Interest Trust or be liable for the breach or failure of any
     obligation, representation, warranty or covenant made or undertaken by the
     Supplemental Interest Trust under this Agreement.

(o)  SEVERABILITY. If any term, provision, covenant, or condition of this
     Agreement, or the application thereof to any party or circumstance, shall
     be held to be invalid or unenforceable (in whole or in part) in any
     respect, the remaining terms, provisions, covenants, and conditions hereof
     shall continue in full force and effect as if this Agreement had been
     executed with the invalid or unenforceable portion eliminated, so long as
     this Agreement as so modified continues to express, without material
     change, the original intentions of the parties as to the subject matter of
     this Agreement and the deletion of such portion of this Agreement will not
     substantially impair the respective benefits or expectations of the
     parties; provided, however, that this severability provision shall not be
     applicable if any provision of Section 2, 5, 6, or 13 (or any definition or
     provision in Section 14 to the extent it relates to, or is used in or in
     connection with any such Section) shall be so held to be invalid or
     unenforceable.

     The parties shall endeavor to engage in good faith negotiations to replace
     any invalid or unenforceable term, provision, covenant or condition with a
     valid or enforceable term, provision, covenant or condition, the economic
     effect of which comes as close as possible to that of the invalid or
     unenforceable term, provision, covenant or condition.

(p)  AGENT FOR PARTY B. Party A acknowledges that Party B has appointed the
     Supplemental Interest Trust Trustee as its agent under the Pooling and
     Servicing Agreement to carry out its obligations hereunder, and that
     Supplemental Interest Trust Trustee shall be entitled to give notices and
     to perform and satisfy the obligations of Party B hereunder on behalf of
     Party B.

(q)  ESCROW PAYMENTS. If (whether by reason of the time difference between the
     cities in which payments are to be made or otherwise) it is not possible
     for simultaneous payments to be made on any date on which both parties are
     required to make payments hereunder, either Party may at its option and in
     its sole discretion notify the other Party that payments on that date are
     to be made in escrow. In this case deposit of the payment due earlier on
     that date shall be made by 2:00 pm (local time at the place for the earlier
     payment) on that date with an escrow agent selected by the notifying party,
     accompanied by irrevocable payment instructions (i) to release the
     deposited payment to the intended recipient upon receipt by the escrow
     agent of the required deposit of any corresponding payment payable by the
     other party on the same date accompanied by irrevocable payment
     instructions to the same effect or (ii) if the required deposit of the
     corresponding payment is not made on that same date, to return the payment
     deposited to the party that paid it into escrow. The party that elects to
     have payments made in escrow shall pay all costs of the escrow
     arrangements.

(r)  CONSENT TO RECORDING. Each party hereto consents to the monitoring or
     recording, at any time and from time to time, by the other party of any and
     all communications between trading, marketing, and operations personnel of
     the parties and their Affiliates, waives any further notice of such
     monitoring or recording, and agrees to notify such personnel of such
     monitoring or recording.

(s)  WAIVER OF JURY TRIAL. Each party waives any right it may have to a trial by
     jury in respect of any in respect of any suit, action or proceeding
     relating to this Agreement or any Credit Support Document.

          Value of any Eligible Credit Support or Posted Credit Support for that

     3.   As to each Mortgage Loan so noted on the attached schedule, all or

          (ii)(A) the enforceability thereof be limited (1) by bankruptcy
          insolvency, moratorium, receivership, or other similar law relating to
          creditors' rights generally or (2) due to acceleration in connection
          with a foreclosure or other involuntary payment, or (B) the

ZBB ENERGY CORPORATION

Placement Agent Warrant to Purchase Shares of Common Stock

			
	 Warrant
No: ___
	 	Number of Shares: 2,040,391

     THIS CERTIFIES THAT, for value received,
         
              
           
          
            
    , or its
registered assigns (the “Holder”), is entitled to purchase from ZBB Energy Corporation, a
Wisconsin corporation (the “Company”), at any time or from time to time during the period
specified in Section 2 hereof, in whole or in part, 2,040,391 fully paid and non-assessable shares
of the Company’s common stock, par value $.01 per share (the “Common Stock”). This warrant
(the “Warrant”) is originally issued as of September 30, 2006.

     The per share exercise price shall be $0.19 per share (the “Initial Exercise Price”). The term
“Warrant Shares,” as used herein, refers to the shares of Common Stock purchasable hereunder. The
Warrant Shares and the Initial Exercise Price are subject to adjustment as provided in Paragraph 4
hereof.

     This Warrant is issued to the Holder in consideration of acting as placement agent pursuant to
private placement of 15% Convertible Promissory Notes issued between April 2006 and September 2006
by the Company (each, a “Note”). The Holder of this Warrant shall also be subject to a
lock-up agreement (the “Lock-Up Agreement”) with the Company. Each capitalized term used herein,
and not otherwise defined, shall have the meaning ascribed thereto in the Notes.

     This Warrant is subject to the following terms, provisions, and conditions:

1. Manner of Exercise; Issuance of Certificates; Payment for Shares.

     (a) General. Subject to the provisions hereof, this Warrant may be exercised at any
time prior to the Expiration Date (as defined below), by the Holder, in whole or in part, by the
surrender of this Warrant, together with a completed exercise agreement in the form attached hereto
(the “Exercise Agreement”), to the Company’s transfer agent (the “Transfer Agent”)

 

 

during normal business hours on any business day at the Transfer Agent’s principal executive
offices (or such other office or agency of the Transfer Agent as it may designate by notice to the
Holder hereof), together with payment to the Company of the Exercise Price for the Warrant Shares
specified in the Exercise Agreement in cash, by certified or official bank check or by wire
transfer for the account of the Company, except as otherwise set forth below. The Warrant Shares
so purchased shall be deemed to be issued to the Holder hereof or such Holder’s designee, as the
record owner of such shares, as of the close of business on the date on which this Warrant shall
have been surrendered, the completed Exercise Agreement shall have been delivered, and payment
shall have been made for such Warrant Shares as set forth above. The Company shall cause
certificates for the Warrant Shares so purchased, representing the aggregate number of Warrant
Shares specified in the Exercise Agreement, to be delivered by the Transfer Agent to the Holder
hereof within a reasonable time, not exceeding three (3) business days after this Warrant shall
have been so exercised, together with cash in lieu of any fraction of a share, as hereinafter
provided. The certificates so delivered shall be in such denominations as may be requested by the
Holder hereof and shall be registered in the name of such Holder or such other name as shall be
designated by such Holder. If this Warrant shall have been exercised only in part, then, unless
this Warrant has expired, the Company shall cause the Transfer Agent to, at Company’s expense, at
the time of delivery of such certificates, deliver to the Holder a new Warrant representing the
number of Warrant Shares with respect to which this Warrant shall not then have been exercised,
which new Warrant shall in all other respects be identical with this Warrant.

     (b) Cashless Exercise. If, at any time following the expiration of one (1) year after
the closing of the Company’s underwritten offering, but not later than two (2) years after the date
of issue hereof), the Holder desires to exercise all or any portion of this Warrant and the Warrant
Shares are not the subject of an effective registration statement under the Securities Act, then,
in lieu of payment of the Exercise Price in cash, the Holder may make such payment, by way of
cashless exercise, as follows:

          (i) by delivery of shares of Common Stock with an aggregate Market Price (as defined below) on
the date of exercise equal to the Exercise Price, subject, however, to the provisions of Section
16(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); or

          (ii) through the written election of the Holder to have withheld by the Company from the
shares of Common Stock otherwise deliverable upon exercise, Common Stock having an aggregate Market
Price on the date of exercise equal to the Exercise Price.

     (c) Failure to Deliver Certificates for Warrant Shares upon Exercise. If the Company
or its Transfer Agent shall fail for any reason or for no reason to issue to the Holder, within ten
(10) days of receipt of the Exercise Agreement (including payment of the full amount of the
Exercise Price for that portion of this Warrant exercised as specified in such Exercise Agreement,
whether in cash or by way of cashless exercise, if permitted by Section 1(b)), a certificate for
the number of Warrant Shares to which the Holder is entitled or to credit the

 

 

Holder’s balance
account with The Depository Trust Company for such number of Warrant
Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant, the Company
shall, in addition to any other remedies under this Warrant or otherwise available to such Holder,
pay as additional damages in cash to such Holder on each day the issuance of such certificate for
Warrant Shares is not timely effected an amount equal to 0.025% of the product of (A) the sum of
the number of Warrant Shares not issued to the Holder on a timely basis and to which the Holder is
entitled, and (B) the Market Price of the Common Stock for the trading day immediately preceding
the last possible date which the Company could have issued such Common Stock to the Holder without
violating this Section 1.

     (d) Failure to Deliver Certificates for Warrant Shares upon Exercise. If within ten
(10) days after the Company’s receipt of the Exercise Agreement (including payment of the full
amount of the Exercise Price for that portion of this Warrant exercised as specified in such
Exercise Agreement whether in cash or by way of cashless exercise, if permitted by Section 1(b)),
the Company fails to deliver a new Warrant to the Holder for the number of Warrant Shares, if any,
to which such Holder remains entitled pursuant to Section 1 hereof, then, in addition to any other
available remedies under this Warrant, or otherwise available to such Holder, the Company shall pay
as additional damages in cash to such Holder on each day after such tenth (10th) day
that such delivery of such new Warrant is not timely effected in an amount equal to 0.25% of the
product of (A) the number of Warrant Shares represented by the portion of this Warrant which is not
being exercised and (B) the Market Price of the Common Stock for the trading day immediately
preceding the last possible date which the Company could have issued such Warrant to the Holder
without violating this Section 1(d).

     (e) Limitation on Exercise. Notwithstanding anything in this Warrant to the
contrary, in no event shall the Holder be entitled to exercise this Warrant for a number of Warrant
Shares (or portions thereof) in excess of that number of Warrant Shares which, upon giving effect
to such exercise, would cause the aggregate number of shares of Common Stock beneficially owned by
the Holder to exceed 4.99% of the outstanding shares of Common Stock following such exercise,
except within sixty (60) days of the Expiration Date. For purposes of the foregoing, the aggregate
number of shares of Common Stock beneficially owned by the Holder shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to which the
determination is being made, but shall exclude shares of Common Stock which would be issuable upon
(i) exercise of the remaining, unexercised Warrants beneficially owned by the Holder and (ii)
exercise or conversion of the unexercised or unconverted portion of any other securities of the
Company beneficially owned by the Holder (including, without limitation, any convertible notes or
preferred stock) subject to a limitation on conversion or exercise analogous to the limitation
contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph,
beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. For
purposes of this Warrant, in determining the number of outstanding shares of Common Stock the
Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the
Company’s most recent Form 10-QSB or Form 10-KSB, as the case may be, (2) a more recent public
announcement by the Company or (3) any other notice by the Company or its Transfer Agent setting
forth the number

 

 

of shares of Common Stock outstanding. Upon the written request of any holder,
the Company
shall promptly, but in no event later than one business day following the receipt of such
notice, confirm in writing to the Holder the number of shares of Common Stock then outstanding. In
any case, the number of outstanding shares of Common Stock shall be determined after giving effect
to the exercise of this Warrant by the Holder since the date as of which such number of outstanding
shares of Common Stock was reported.

2. Period of Exercise. This Warrant is exercisable at any time or from time to time after
the date hereof until 5:00 p.m. New York City time, on September 30, 2011 (such time and date, the
“Expiration Date”).

3. Certain Agreements of
the Company. The Company hereby covenants and
agrees as follows:

     (a) Shares to be Fully Paid. All Warrant Shares will, upon issuance in accordance
with the terms of this Warrant, be validly issued, fully paid, and non-assessable and free from all
taxes, liens, and charges with respect to the issue thereof.

     (b) Reservation of Shares. The Company covenants and agrees that it shall reserve and
set apart and have at all times, free from preemptive rights, the number of authorized but unissued
shares of Common Stock deliverable upon the exercise in full of this Warrant, and it shall have at
all times any other rights or privileges provided for therein sufficient to enable it at any time
to fulfill all of its obligations hereunder. If at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient to permit the exercise in full of this Warrant, the
Company will take such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purpose, including, without limitation, taking appropriate board action,
recommending such an increase to the holders of Common Stock, holding stockholders’ meetings and
soliciting votes and proxies in favor of such increase to obtain the requisite stockholder
approval, and upon such approval, the Company shall reserve and keep available such additional
shares solely for the purpose of permitting the exercise of this Warrant.

     (c) Registration of Shares. The Company shall arrange for the registration of the
Warrant Shares with the Securities and Exchange Commission in accordance with the Investor Rights
Agreement, of even date herewith, by and between the Holder and the Company.

     (d) Certain Actions Prohibited. The Company will not, by amendment of its charter or
through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale
of securities, or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed by it hereunder, but will at all times in good
faith assist in the carrying out of all the provisions of this Warrant and in the taking of all
such action as may reasonably be requested by the Holder of this Warrant in order to protect the
exercise privilege of the Holder of this Warrant against impairment, consistent with the tenor and
purpose of this Warrant. Without limiting the generality of the foregoing, the Company (i) will

 

 

not increase the par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the Exercise Price then in effect, and (ii) will take all such actions as may be
necessary or appropriate in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant.

     (e) Successors and Assigns. This Warrant will be binding upon the Company and any
entity succeeding to the Company by merger, consolidation, or acquisition of all or substantially
all the Company’s assets or otherwise; provided, however, that such assignee
remains subject to the Lock-Up Agreement.

4. Antidilution Provisions. Until the Expiration Date, the Exercise Price and the number
of Warrant Shares shall be subject to adjustment from time to time as provided in this Paragraph 4.

          In the event that any adjustment of the Exercise Price as required herein results in a
fraction of a cent, such Exercise Price shall be rounded up to the nearest cent.

     (a) Subdivision or Combination of Common Stock. If the Company at any time shall:

     (i) take a record of the holders of its Common Stock for the purpose of entitling them
to receive a dividend payable in, or other distribution of, shares of Common Stock,

     (ii) subdivide (by any stock split, stock dividend, recapitalization, reorganization,
reclassification or otherwise) its outstanding shares of Common Stock into a greater number
of shares of Common Stock, or

     (iii) combine (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) its outstanding shares of Common Stock into a smaller number
of shares of Common Stock,

then (x) the number of shares of Common Stock for which this Warrant is exercisable immediately
after the occurrence of any such event shall be adjusted to equal the number of shares of Common
Stock which a record holder of the same number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the occurrence of such event would own or be entitled to receive
after the happening of such event, and (y) the Exercise Price shall be adjusted to equal (A) the
Exercise Price multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of shares for which this
Warrant is exercisable immediately after such adjustment.

 

 

     (b) Consolidation, Merger or Sale. In case the Company after the date hereof shall
(i) consolidate with or merge into any other entity and shall not be the continuing or surviving
corporation of such consolidation or merger, or permit any other entity to consolidate with or
merge into the Company and the Company shall be the continuing or surviving corporation, but, in
connection with such consolidation or merger, the Common Stock shall be changed into or exchanged
for stock or other securities of any other entity or cash or any other property, (ii) sell, convey
or otherwise transfer all or substantially all of its properties or assets to any other entities in
one or more related transactions or (iii) effect a capital reorganization or reclassification of
the Common Stock, then as a condition of such consolidation, merger or sale or conveyance, the
Company shall make or cause to be made adequate provision whereby the Holder of this Warrant will
have the right to acquire and receive upon exercise of this Warrant in lieu of the shares of Common
Stock immediately theretofore acquirable upon the exercise of this Warrant, the Holder of this
Warrant, upon the exercise hereof at any time after the consummation of such transaction, shall be
entitled to receive (at the aggregate Exercise Price in effect at the time of such consummation for
all Common Stock issuable upon such exercise immediately prior to such consummation), in lieu of
the Common Stock issuable upon such exercise prior to such consummation, the amount of securities,
cash or other property to which such Holder would actually have been entitled as a stockholder upon
such consummation if such Holder had exercised this Warrant immediately prior thereto, subject to
adjustments (subsequent to such consummation) as nearly equivalent as possible to the adjustments
provided for in this Paragraph 4. In any such case, the Company will make appropriate provision to
ensure that the provisions of this Paragraph 4 hereof will thereafter be applicable as nearly as
may be in relation to any shares of stock or securities thereafter deliverable upon the exercise of
this Warrant. The Company will not effect any consolidation, merger or sale or conveyance unless
prior to the consummation thereof, the successor corporation (if other than the Company) assumes by
written instrument this Warrant, including, without limitation, the obligations under this
Paragraph 4 and the obligations to deliver to the Holder of this Warrant such shares of stock,
securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to
acquire.

     (c) Distribution of Assets. In case the Company shall declare or make any
distribution of its assets (including cash) to holders of Common Stock as a partial liquidating
dividend, by way of return of capital or otherwise, then, after the date of record for determining
stockholders entitled to such distribution, but prior to the date of distribution, the Holder of
this Warrant shall be entitled upon exercise of this Warrant for the purchase of any or all of the
shares of Common Stock subject hereto, to receive the amount of such assets which would have been
payable to the Holder had such Holder been the holder of such shares of Common Stock on the record
date for the determination of stockholders entitled to such distribution.

     (d) Notice of Adjustment. Upon the occurrence of any event which requires any
adjustment pursuant to this Paragraph 4, then, and in each such case, the Company shall give notice
thereof to the Holder of this Warrant, which notice shall state the Exercise Price resulting from
such adjustment and the increase or decrease in the number of Warrant Shares purchasable at such
Exercise Price upon exercise, setting forth in reasonable detail the method of calculation

 

 

and the facts upon which such calculation is based. Such calculation shall be certified by
the principal financial officer of the Company.

     (e) Minimum Adjustment of Exercise Price. No adjustment of the Exercise Price shall
be made in an amount of less than $0.01, but any such lesser adjustment shall be carried forward
and shall be made at the time and together with the next subsequent adjustment which, together with
any adjustments so carried forward, shall amount to not less than $0.01.

     (f) No Fractional Shares. No fractional shares of Common Stock are to be issued upon
the exercise of this Warrant, but the Company shall pay a cash adjustment in respect of any
fractional share which would otherwise be issuable in an amount equal to the same fraction of the
Market Price of a share of Common Stock on the date of such exercise.

     (g) Other Notices. In case at any time:

          (i) the Company shall declare any dividend upon the Common Stock payable in shares of stock of
any class or make any other distribution (including dividends or distributions payable in cash out
of retained earnings) to the holders of the Common Stock;

          (ii) the Company shall offer for subscription pro rata to the holders of the Common Stock any
additional shares of stock of any class or other rights;

          (iii) there shall be any capital reorganization of the Company, or reclassification of the
Common Stock, or consolidation or merger of the Company with or into, or sale of all or
substantially all its assets to, another corporation or entity; or

          (iv) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the
Company;

               then, in each such case, the Company shall give to the Holder of this Warrant (a) notice of
the date on which the books of the Company shall close or a record shall be taken for determining
the holders of Common Stock entitled to receive any such dividend, distribution, or subscription
rights or for determining the holders of Common Stock entitled to vote in respect of any such
reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding-up, notice of the date (or, if not then known, a
reasonable approximation thereof by the Company) when the same shall take place. Such notice shall
also specify the date on which the holders of Common Stock shall be entitled to receive such
dividend, distribution, or subscription rights or to exchange their Common Stock for stock or other
securities or property deliverable upon such reorganization, re-classification, consolidation,
merger, sale, dissolution, liquidation, or winding-up, as the case may be. Such notice shall be
given at least 30 days prior to the record date or the date on which the Company’s books are closed
in respect thereto. In furtherance of the foregoing, the Holder

 

 

shall be entitled to the same rights to receive notice of corporate action as any holder of
Common Stock.

     (h) Certain Events. If any event occurs of the type contemplated by the adjustment
provisions of this Paragraph 4 but not expressly provided for by such provisions, the Company will
give notice of such event as provided in Paragraph 4(d) hereof, and the Company’s Board of
Directors will make an appropriate adjustment in the Exercise Price and the number of shares of
Common Stock acquirable upon exercise of this Warrant so that the rights of the Holder shall be
neither enhanced nor diminished by such event.

          (i) Certain Definitions.

          (i) “Market Price,” as of any date, (i) means the average of the last reported sale
prices for the shares of Common Stock on the Over-the-Counter Bulletin Board (the “OTC Bulletin
Board”) for the ten (10) trading days immediately preceding such date as reported by Bloomberg, or
(ii) if the OTC Bulletin Board is not the principal trading market for the shares of Common Stock,
the average of the last reported sale prices on the principal trading market for shares of Common
Stock during the same period as reported by Bloomberg, or (iii) if market value cannot be
calculated as of such date on any of the foregoing bases, the Market Price shall be the fair market
value as reasonably determined in good faith by (a) the Board of Directors of the Company or, at
the option of a majority-in-interest of the Holders of the outstanding Warrants by (b) an
independent investment bank of nationally recognized standing in the valuation of businesses
similar to the business of the Company. The manner of determining the Market Price of the shares of
Common Stock set forth in the foregoing definition shall apply with respect to any other security
in respect of which a determination as to market value must be made hereunder.

          (ii) “Common Stock” includes the Common Stock, par value $.01 per share, and any
additional class of stock of the Company having no preference as to dividends or distributions on
liquidation, provided that the shares purchasable pursuant to this Warrant shall include shares of
Common Stock, par value $.01 per share, in respect of which this Warrant is exercisable, or shares
resulting from any subdivision or combination of such Common Stock, or in the case of any
reorganization, reclassification, consolidation, merger, or sale of the character referred to in
Paragraph 4(b) hereof, the stock or other securities or property provided for in such Paragraph.

          (iii) “Exercise Price” means the Initial Exercise Price, as adjusted from
time to time pursuant to the provisions of this Paragraph 4.

5. Issue Tax. The issuance of certificates for Warrant Shares upon the exercise of this
Warrant shall be made without charge to the Holder of this Warrant or such shares for any issuance
tax or other costs in respect thereof, provided that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and

 

 

delivery of any certificate in a name other than the Holder of this Warrant, or any capital gains,
income, VAT, or other similar taxes of any Holder.

6. No Rights or Liabilities as a Stockholder. This Warrant shall not entitle the Holder
hereof to any voting rights or other rights as a stockholder of the Company. No provision of this
Warrant, in the absence of affirmative action by the Holder hereof to purchase Warrant Shares, and
no mere enumeration herein of the rights or privileges of the Holder hereof, shall give rise to any
liability of such Holder for the Exercise Price or as a stockholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

7. Transfer, Exchange, and Replacement of Warrant.

     (a) Restriction on Transfer. This Warrant and the rights granted to the Holder hereof
are transferable, in whole or in part, upon surrender of this Warrant, together with a properly
executed assignment in the form attached hereto, at the office or agency of the Company referred to
in Paragraph 7(e) below, provided, however, that any transfer or assignment shall be subject to the
conditions set forth in Paragraph 7(f) hereof and to the applicable provisions of the Investor
Rights Agreement. Until due presentment for registration of transfer on the books of the Company,
the Company may treat the registered Holder hereof as the owner and Holder hereof for all purposes,
and the Company shall not be affected by any notice to the contrary.

     (b) Warrant Exchangeable for Different Denominations. This Warrant is exchangeable,
upon the surrender hereof by the Holder hereof at the office or agency of the Company referred to
in Paragraph 7(e) below, for new Warrants of like tenor representing in the aggregate, the right to
purchase the number of shares of Common Stock or other securities which may be purchased hereunder,
each of such new Warrants to represent the right to purchase such number of shares as shall be
designated by the Holder hereof at the time of such surrender.

     (c) Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such
loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in
form and amount to the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and deliver, in lieu
thereof, a new Warrant of like tenor.

     (d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant in
connection with any transfer, exchange, or replacement as provided in this Paragraph 7, this
Warrant shall be promptly canceled by the Company. The Company shall pay all taxes (other than
securities transfer taxes) and all other expenses (other than legal expenses, if any, incurred by
the Holder or transferees) and charges payable in connection with the preparation, execution, and
delivery of Warrants pursuant to this Paragraph 7.

 

 

     (e) Register. The Company shall maintain, at its principal executive offices (or such
other office or agency of the Company as it may designate by notice to the Holder hereof), a
register for this Warrant, in which the Company shall record the name and address of the person in
whose name this Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

     (f) Exercise or Transfer Without Registration. If, at the time of the surrender of
this Warrant in connection with any exercise, transfer, or exchange of this Warrant, this Warrant
(or, in the case of any exercise, the Warrant Shares issuable hereunder), shall not be registered
under the Securities Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, transfer, or exchange, (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written opinion of
counsel, which opinion and counsel are reasonably acceptable to the Company, to the effect that
such exercise, transfer, or exchange may be made without registration under the Securities Act and
under applicable state securities or blue sky laws, (ii) that the Holder or transferee execute and
deliver to the Company an investment letter in form and substance reasonably acceptable to the
Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a)
promulgated under the Securities Act; provided that no such opinion, letter or status as an
“accredited investor” shall be required in connection with a transfer pursuant to Rule 144 under
the Securities Act. The first Holder of this Warrant, by taking and holding the same, represents
to the Company that such Holder is acquiring this Warrant for investment and not with a view to the
distribution hereof.

8. Notices. All notices, requests, and other communications required or permitted to be
given or delivered hereunder to the Holder of this Warrant shall be in writing, and shall be
personally delivered, or shall be sent by certified or registered mail or by recognized overnight

Company. Any such notice, request, or other communication may be sent by facsimile, but shall in
such case be subsequently confirmed by a writing personally delivered or sent by certified or
registered mail or by recognized overnight mail courier as provided above. All notices, requests,
and other communications shall be deemed to have been given either at the time of the receipt
thereof by the person entitled to receive such notice at the address of such person for purposes of
this Paragraph 8, or, if mailed by registered or certified mail or with a recognized overnight mail
courier upon deposit with the United States Post Office or such overnight mail courier, if postage
is prepaid and the mailing is properly addressed, as the case may be.
