Delaware corporation, as Seller (the "Seller"), WILSHIRE CREDIT CORPORATION, a
Nevada corporation, as servicer (a "Servicer" or "Wilshire"), INDYMAC BANK,
F.S.B., a federal savings bank, as servicer (a "Servicer" or "IndyMac", and
together with Wilshire, the "Servicers") and JPMORGAN CHASE BANK, NATIONAL

United States, as trustee (the "Trustee").


                                 WITNESSETH THAT

                  In consideration of the mutual agreements herein contained,
the parties hereto agree as follows:


                              PRELIMINARY STATEMENT

                  The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust Fund created hereunder. The Certificates will consist of twenty
classes of certificates, designated as (i) the Class A-1 Certificates, (ii) the
Class A-2 Certificates, (iii) the Class A-3 Certificates, (iv) the Class M-1
Certificates, (v) the Class M-2 Certificates, (vi) the Class M-3 Certificates,
(vii) the Class M-4 Certificates, (viii) the Class M-5 Certificates, (ix) the
Class M-6 Certificates, (x) the Class M-7 Certificates, (xi) the Class M-8
Certificates, (xii) the Class M-9 Certificates, (xiii) the Class B-1
Certificates, (xiv) the Class B-2 Certificates, (xv) the Class P Certificates,
(xvi) the Class X-1 Certificates, (xvii) the Class X-2 Certificates, (xviii) the

                                     -------

As provided herein, the Trustee will make an election to treat the segregated
pool of assets consisting of the Mortgage Loans and certain other related assets
subject to this Agreement (exclusive of the Pre-Funding Account) as a real
estate mortgage investment conduit (a "REMIC") for federal income tax purposes,
and such segregated pool of assets will be designated as "REMIC 1." The Class
A-RL Certificates will represent the sole class of "residual interests" in REMIC
1 for purposes of the REMIC Provisions (as defined herein) under federal income
tax law. The following table irrevocably sets forth the designation, the
Uncertificated REMIC 1 Pass-Through Rate and the initial Uncertificated
Principal Balance for each of the "regular interests" in REMIC 1 (the "REMIC 1
Regular Interests"). None of the REMIC 1 Regular Interests will be certificated.
The latest possible maturity date (determined for purposes of satisfying
Treasury regulation Section 1.860G-1(a)(4)(iii)) of each of the REMIC 1 Regular
Interests will be the Latest Possible Maturity Date as defined herein.

                  As provided herein, an election will be made to treat the
segregated pool of assets consisting of the REMIC 1 Regular Interests as a REMIC
for federal income tax purposes, and such segregated pool of assets will be

         Pass-Through Rate.

(2)      REMIC 2 Regular Interest MTI-S will not have an Uncertificated REMIC 2
         Pass-Through Rate, but will be entitled to 100% of the amounts
         distributed on REMIC 1 Regular Interest LTI-S.

(3)      REMIC 2 Regular Interest MTI-S will not have an Uncertificated
         Principal Balance, but will have an Uncertificated Notional Amount
         equal to the Uncertificated Notional Amount of REMIC 1 Regular Interest
         LTI-S.

                                     -------

                  As provided herein, an election will be made to treat the
segregated pool of assets consisting of the REMIC 2 Regular Interests as a REMIC
for federal income tax purposes, and such segregated pool of assets will be
designated as REMIC 3. The Class R-3 Interest will represent the sole class of
"residual interests" in REMIC 3 for purposes of the REMIC Provisions under
federal income tax law (the "Class R-3 Interest"). The following table
irrevocably sets forth the designation, Pass-Through Rate, aggregate Initial
Certificate Principal Balance and minimum denominations for each Class of
Certificates comprising the interests representing "regular interests" in REMIC
3, and the Class A-R Certificates, Class A-RL Certificates and Class X-2
Certificates which are not "regular interests" in REMIC 3. The latest possible
maturity date (determined solely for purposes of satisfying Treasury regulation
Section 1.860G-1(a)(4)(iii)) of each of the Regular Certificates will be the
Latest Possible Maturity Date as defined herein.

(7)      The Class X-S Certificates are an interest only Class and for each
         Distribution Date the Class X-S Certificates shall receive the
         aggregate Excess Servicing Fee. For federal income tax purposes, the
         Class X-S Certificates will not have a Pass-Through Rate, but will be

qualified as such under the laws of the state of its principal place of business
and each state having jurisdiction over such insurer in connection with the

states to transact a mortgage guaranty insurance business in such states and to
write the insurance provided by the insurance policy issued by it, approved as a
Fannie Mae- or Freddie Mac-approved mortgage insurer or having a claims paying
ability rating of at least "AA" or equivalent rating by at least two nationally

substituted by the Seller for a Deleted Mortgage Loan which must, on the date of
such substitution, as confirmed in a Request for Release, substantially in the

in the case of a substitution of more than one mortgage loan for a Deleted
Mortgage Loan, an aggregate principal balance), not in excess of, and not more
than 10% less than the Stated Principal Balance of the Deleted Mortgage Loan;
(ii) be accruing interest at a rate no lower than and not more than 1% per annum
higher than, that of the Deleted Mortgage Loan; (iii) have a Combined
Loan-to-Value Ratio no higher than that of the Deleted Mortgage Loan; (iv) have
a remaining term to maturity no greater than (and not more than one year less
than that of) the Deleted Mortgage Loan; and (v) comply with each representation
and warranty set forth in Section 2.03(f).

                  Rating Agency: Fitch and Moody's. If either such organization

nationally recognized statistical rating organization, or other comparable
Person, as is designated by the Depositor, notice of which designation shall be

liquidation, plus (ii) interest at the Net Mortgage Rate from the related Due
Date as to which interest was last paid or advanced (and not reimbursed) to the
related Certificateholders up to the related Due Date in the month in which
Liquidation Proceeds are required to be distributed on the Stated Principal
Balance of such Liquidated Mortgage Loan from time to time, minus (iii) the
Liquidation Proceeds, if any, received during the month in which such
liquidation occurred, to the extent applied as recoveries of interest at the Net
Mortgage Rate and to principal of the Liquidated Mortgage Loan. Any Charged Off
Loan will



                                       30
<PAGE>


give rise to a Realized Loss (calculated as if clause (iii) of the previous
sentence is equal to zero) at the time it is charged off, as described in
Section 3.11(a)(iii) hereof.

                  If a Servicer receives Net Recoveries with respect to any
Charged Off Loan, the amount of the Realized Loss with respect to that Charged
Off Loan will be reduced to the extent such recoveries are applied to principal
distributions on any Distribution Date.

11:00 A.M., London, England time, on the second LIBOR Business Day prior to the
first day of such Interest Accrual Period to prime banks in the London interbank
market for a period of one month in amounts approximately equal to the aggregate
Class Principal Balance of the LIBOR Certificates; provided that at least two
such Reference Banks provide such rate. If fewer than two offered rates appear,
the Reference Bank Rate will be the arithmetic mean of the rates quoted by one
or more major banks in New York City, selected by the Trustee, as of 11:00 a.m.,
New York time, on such date for loans in U.S. Dollars to leading European Banks
for a period of one month in amounts approximately equal to the aggregate Class
Principal Balance of the LIBOR Certificates. If no such quotations can be
obtained, the Reference Bank Rate shall be LIBOR applicable to the preceding
Distribution Date; provided however, that if, under the priorities indicated
above, LIBOR for a Distribution Date would be based on LIBOR for the previous
Payment Date for the third consecutive Distribution Date, the Trustee shall

Accrued Interest for the REMIC 2 Regular Interests for any Distribution Date,

         authorized agent either on its face or by an acknowledged closing
         instruction or escrow letter.

                  In the event the Seller delivers to the Trustee certified
copies of any document or instrument set forth in 2.01(b) because of a delay
caused by the public recording office in returning any recorded document, the
Seller shall deliver to the Trustee, within 60 days of the Closing Date, an
Officer's Certificate which shall (i) identify the recorded document, (ii) state
that the recorded document has not been delivered to the Trustee due solely to a
delay caused by the public recording office, and (iii) state the amount of time
generally required by the applicable recording office to record and return a
document submitted for recordation.

                  In the event that in connection with any Mortgage Loan the
Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim
recorded assignments or (c) the lender's title policy (together with all riders
thereto) satisfying the requirements set forth above, concurrently with the
execution and delivery hereof because such document or documents have not been
returned from the applicable public recording office in the case of clause (a)
or (b) above, or because the title policy has not been delivered to the Seller
or the Depositor by the applicable title insurer in the case of clause (c)
above, the Depositor shall promptly deliver to the Trustee, in the case of
clause (a) or (b) above, such original Mortgage or such interim



                                       50

assignment, as the case may be, with evidence of recording indicated thereon
upon receipt thereof from the public recording office, or a copy thereof,
certified, if appropriate, by the relevant recording office and in the case of
clause (c) above, if such lender's title policy is received by the Depositor,
upon receipt thereof.

                  As promptly as practicable subsequent to such transfer and
assignment, and in any event, within thirty (30) days thereafter, the Trustee
shall (at the Seller's expense) (i) affix the Trustee's name to each Assignment
of Mortgage, as the assignee thereof, (ii) cause such assignment to be in proper
form for recording in the appropriate public office for real property records
within thirty (30) days after receipt thereof and (iii) cause to be delivered
for recording in the appropriate public office for real property records the
assignments of the Mortgages to the Trustee, except that, with respect to any
assignment of a Mortgage as to which the Trustee has not received the
information required to prepare such assignment in recordable form, the
Trustee's obligation to do so and to deliver the same for such recording shall
be as soon as practicable after receipt of such information and in any event
within thirty (30) days after the receipt thereof, and the Trustee need not
cause to be recorded (a) any assignment referred to in clause (iii) above which
relates to a Mortgage Loan in any jurisdiction under the laws of which, as
evidenced by an Opinion of Counsel delivered to the Trustee (at the Depositor's
expense, provided such expense has been previously approved by the Depositor in
writing) within 180 days of the Closing Date, acceptable to the Rating Agencies,
the recordation of such assignment is not necessary to protect the Trustee's and
the Certificateholders' interest in the related Mortgage Loan or (b) if MERS is
identified on the Mortgage or on a properly recorded assignment of the Mortgage
as the mortgagee of record solely as nominee for the Seller and its successors
and assigns.

                  In connection with the assignment of any Mortgage Loan
registered on the MERS(R) System, the Depositor further agrees that it will
cause, at the Depositor's own expense, on or prior to the Closing Date, the
MERS(R) System to indicate that such Mortgage Loans have been assigned by the
Depositor to the Trustee in accordance with this Agreement for the benefit of
the Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer files
(a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY THE
FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such
Mortgage Loans. The Depositor further agrees that it will not, and will not
permit any Servicer to, and each Servicer agrees that it will not, alter the
codes referenced in this paragraph with respect to any Mortgage Loan during the
term of this Agreement unless and until such Mortgage Loan is repurchased in
accordance with the terms of this Agreement.

                  (c)      The Trustee is authorized to appoint any bank or
trust company approved by the Depositor as Custodian of the documents or
instruments referred to in this Section 2.01 for any of the Mortgage Loans, and
to enter into a Custodial Agreement for such purpose and any documents delivered
thereunder shall be delivered to the Custodian and any Officer's Certificates
delivered with respect thereto shall be delivered to the Trustee and the
Custodian.

                  (d)      It is the express intent of the parties to this
Agreement that the conveyance of the Mortgage Loans by the Depositor to the
Trustee as provided in this Section 2.01 be, and be construed as, a sale of the
Mortgage Loans by the Depositor to the Trustee. It is, further, not the
intention of the parties to this Agreement that such conveyance be deemed a
pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt or
other obligation of the Depositor. However, in the event that, notwithstanding
the intent of the parties to this Agreement, the Mortgage Loans are held to be
the property of the Depositor, or if for any other reason this Agreement is held
or deemed to create a security interest in the Mortgage Loans then (a) this
Agreement shall also be deemed to be a security agreement within the meaning of
Articles 8 and 9 of the New York Uniform Commercial Code; (b) the conveyance
provided for in this Section 2.01 shall be deemed to be a grant by the Depositor
to the Trustee for the benefit of the Certificateholders of a security interest
in all of the Depositor's right, title and interest in and to the Mortgage Loans
and all amounts payable to the holders of the Mortgage Loans in accordance with
the terms thereof and all proceeds of the conversion, voluntary or involuntary,
of the foregoing into cash, instruments, securities or other property, including
without limitation all amounts, other than investment earnings, from time to
time held or invested in the Certificate Account, whether in the form of cash,
instruments, securities or other property; (c) the possession by the Trustee or
any Custodian of such items of property and such other items of property as
constitute instruments, money, negotiable documents or chattel paper shall be
deemed to be "in possession by the secured party" for purposes of perfecting the
security interest pursuant to Section 9-305 of the New York Uniform Commercial
Code; and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the benefit of the Certificateholders for the purpose of perfecting such
security interest under applicable law (except that nothing in this clause (e)
shall cause any person to be deemed to be an agent of the Trustee for any
purpose other than for perfection of such security interests unless, and then
only to the extent, expressly appointed and authorized by the Trustee in
writing). The Depositor and the Trustee, upon directions from the Depositor,
shall, to the extent consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to create a security
interest in the Mortgage Loans, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement.

                  (e)      The Depositor hereby sells, transfers, assigns, sets
over and otherwise conveys to the Trustee in trust for the benefit of the
Certificateholders, without recourse, all right, title and interest in such
Subsequent Mortgage Loans (which does not include servicing rights), including
all interest and principal due on or with respect to such Subsequent Mortgage
Loans on or after the related Subsequent Transfer Date and all interest and
principal payments on such Subsequent Mortgage Loans received prior to the
Subsequent Transfer Date in respect of installments of interest and principal
due thereafter, but not including principal and interest due on such Subsequent
Mortgage Loans prior to the related Subsequent Transfer Date, any insurance

<PAGE>


                  (g)      Upon (1) delivery to the Trustee by the Depositor of
the Opinions of Counsel referred to in Sections 2.01(f)(ii) and (iii), (2)
delivery to the Trustee by the Depositor of a revised Mortgage Loan Schedule
reflecting the Subsequent Mortgage Loans conveyed on such Subsequent Transfer
Date and the related Subsequent Mortgage Loans and (3) delivery to the Trustee
by the Depositor of an Officer's Certificate confirming the satisfaction of each
of the conditions precedent set forth in Section 2.01(f), the Trustee shall
remit to the Depositor the Aggregate Subsequent Transfer Amount related to the
Subsequent Mortgage Loans transferred by the Depositor on such Subsequent
Transfer Date from funds in the Pre-Funding Account.

                  The Trustee shall not be required to investigate or otherwise
verify compliance with the conditions set forth in the preceding paragraph,
except for its own receipt of documents specified above, and shall be entitled
to rely on the required Officer's Certificate.

                  SECTION 2.02 Acceptance by the Trustee.

                  The Trustee acknowledges receipt by itself or the Custodian of
the documents identified in the Initial Certification in the form annexed hereto
as Exhibit G and declares that it or the Custodian on its behalf hold and will
hold the documents delivered to it or the Custodian, respectively, constituting
the Mortgage Files, and that it or the Custodian holds or will hold such other
assets as are included in the Trust Fund, in trust for the exclusive use and
benefit of all present and future Certificateholders. The Trustee acknowledges
that it or the Custodian will maintain possession of the Mortgage Notes in the
State of Texas or the State of Illinois, as directed by the Seller, unless
otherwise permitted by the Rating Agencies.

                  The Custodian is required under the Custodial Agreement to
execute and deliver on the Closing Date to the Depositor, the Seller, the
Trustee and the Servicers an Initial Certification in the form annexed hereto as
Exhibit G with respect to the Mortgage Loans delivered to the Custodian. The
Trustee shall deliver on the Closing Date to the Depositor, the Seller, the
Trustee and the Servicers an Initial Certification in the form annexed hereto as
Exhibit G with respect to the Mortgage Loans delivered to the Trustee. Based on
its respective review and examination, and only as to the documents identified
in such related Initial Certification, pursuant to the Custodial Agreement, the
Custodian will acknowledge that such documents delivered to it appear regular on
their face and relate to such Mortgage Loan and pursuant to this Agreement the
Trustee will acknowledge that such documents delivered to it appear regular on
their face and relate to such Mortgage Loan. Neither the Trustee nor the
Custodian shall be under any duty or obligation to inspect, review or examine
said documents, instruments, certificates or other papers to determine that the
same are genuine, enforceable or appropriate for the represented purpose or that
they have actually been recorded in the real estate records or that they are
other than what they purport to be on their face.

                  Not later than 90 days after the Closing Date, the Trustee and
the Custodian are each required to deliver to the Depositor, the Seller, the
Trustee and the Servicers a Final Certification with respect to the Mortgage
Loans delivered to it in the form annexed hereto as Exhibit H, with any
applicable exceptions noted thereon.



                                       55
<PAGE>


                  If, in the course of such review, the Trustee or the
Custodian, as applicable, finds any document constituting a part of a Mortgage
File which does not meet the requirements of Section 2.01, the Trustee or,
pursuant to the Custodial Agreement, the Custodian, will list such as an
exception in the Final Certification; provided, however, that neither the
Trustee nor the Custodian shall make any determination as to whether (i) any
endorsement is sufficient to transfer all right, title and interest of the party
so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or
(ii) any assignment is in recordable form or is sufficient to effect the
assignment of and transfer to the assignee thereof under the mortgage to which
the assignment relates.

                  The Seller shall promptly correct or cure such defect within
120 days from the date it was so notified of such defect and, if the Seller does
not correct or cure such defect within such period and such defect materially
and adversely affects the interests of the Certificateholders in the related
Mortgage Loan, the Seller shall either (a) substitute for the related Mortgage
Loan a Qualified Substitute Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, or (b) purchase such Mortgage Loan from the Trustee within 120 days from
the date the Seller was notified of such defect in writing at the Repurchase
Price of such Mortgage Loan; provided, however, that in no event shall such
substitution or repurchase occur more than 540 days from the Closing Date,
except that if the substitution or repurchase of a Mortgage Loan pursuant to
this provision is required by reason of a delay in delivery of any documents by
the appropriate recording office, then such substitution or repurchase shall
occur within 720 days from the Closing Date; and further provided, that the
Seller shall have no liability for recording any Assignment of Mortgage in favor
of the Trustee or for the Trustee's failure to record such Assignment of
Mortgage, and the Seller shall not be obligated to repurchase or cure any
Mortgage Loan solely as a result of the Trustee's failure to record such
Assignment of Mortgage. The Trustee shall deliver written notice to each Rating
Agency within 360 days from the Closing Date indicating each Mortgage Loan (a)
the Assignment of Mortgage which has not been returned by the appropriate
recording office or (b) as to which there is a dispute as to location or status
of such Mortgage Loan. Such notice shall be delivered every 90 days thereafter
until the Assignment of Mortgage for the related Mortgage Loan is returned to
the Trustee or the dispute as to location or status has been resolved. Any such
substitution pursuant to (a) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if
any, and any substitution pursuant to (a) above shall not be effected prior to
the additional delivery to the Trustee of a Request for Release substantially in
the form of Exhibit M. No substitution is permitted to be made in any calendar
month after the Determination Date for such month. The Repurchase Price for any
such Mortgage Loan shall be deposited by the Seller in the Certificate Account
on or prior to the Business Day immediately preceding such Distribution Date in
the month following the month of repurchase and, upon receipt of such deposit
and certification with respect thereto in the form of Exhibit M hereto, the
Trustee shall release the related Mortgage File to the Seller and shall execute
and deliver at such entity's request such instruments of transfer or assignment
prepared by such entity, in each case without recourse, as shall be necessary to
vest in such entity, or a designee, the Trustee's interest in any Mortgage Loan
released pursuant hereto. In furtherance of the foregoing, if the Seller is not
a member of MERS and repurchases a Mortgage Loan which is registered on the
MERS(R) System,



                                       56
<PAGE>


the Seller, at its own expense and without any right of reimbursement, shall
cause MERS to execute and deliver an assignment of the Mortgage in recordable
form to transfer the Mortgage from MERS to the Seller and shall cause such
Mortgage to be removed from registration on the MERS(R) System in accordance
with MERS' rules and regulations.

                  Pursuant to the Custodial Agreement, the Custodian is required
to execute and deliver on the Subsequent Transfer Date to the Depositor, the
Seller, the Trustee and the Servicers an Initial Certification in the form
annexed hereto as Exhibit G. Based on its review and examination, and only as to
the documents identified in such Initial Certification, the Custodian shall
acknowledge that such documents appear regular on their face and relate to such
Subsequent Mortgage Loan. Neither the Trustee nor the Custodian shall be under a
duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine, enforceable
or appropriate for the represented purpose or that they have actually been
recorded in the real estate records or that they are other than what they
purport to be on their face.

                  Pursuant to the Custodial Agreement, not later than 90 days
after the end of the Pre-Funding Period, the Custodian is required to deliver to
the Depositor, the Seller, the Trustee and the related Servicer a Final
Certification with respect to the Subsequent Mortgage Loans in the form annexed
hereto as Exhibit H with any applicable exceptions noted thereon.

                  If, in the course of such review of the Mortgage Files
relating to the Subsequent Mortgage Loans, the Custodian finds any document
constituting a part of a Mortgage File which does not meet the requirements of
Section 2.01, pursuant to the Custodial Agreement, the Custodian will be
required to list such as an exception in the Final Certification; provided,
however that neither the Trustee nor the Custodian shall make any determination
as to whether (i) any endorsement is sufficient to transfer all right, title and
interest of the party so endorsing, as noteholder or assignee thereof, in and to
that Mortgage Note or (ii) any assignment is in recordable form or is sufficient
to effect the assignment of and transfer to the assignee thereof under the
mortgage to which the assignment relates. The Seller shall cure any such defect
or repurchase or substitute for any such Mortgage Loan in accordance with
Section 2.02(a).

                  It is understood and agreed that the obligation of the Seller
to cure, substitute for or to repurchase any Mortgage Loan which does not meet
the requirements of Section 2.01 shall constitute the sole remedy respecting
such defect available to the Trustee, the Depositor and any Certificateholder
against the Seller.

                  The Trustee shall pay to the Custodian from time to time
reasonable compensation for all services rendered by it hereunder or under the
Custodial Agreement, and the Trustee shall pay or reimburse the Custodian upon
its request for all reasonable expenses, disbursements and advances incurred or
made by the Custodian in accordance with any of the provisions of this Agreement
or the Custodial Agreement, except any such expense, disbursement or advance as
may arise from its negligence or bad faith.

                  SECTION 2.02 Representations and Warranties of the Seller and
                               Servicers.

                  (a)      The Seller hereby makes the representations and
warranties applicable to it set forth in Schedule II hereto, and by this
reference incorporated herein, to the Depositor and the Trustee, as of the
Closing Date, or if so specified therein, as of the Cut-off Date or such other
date as may be specified.

                  (b)      Wilshire, in its capacity as Servicer, hereby makes
the representations and warranties applicable to it set forth in Schedule IIIA
hereto, and by this reference incorporated herein, to the Depositor and the
Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off
Date or such other date as may be specified.

                  (c)      IndyMac, in its capacity as Servicer, hereby makes
the representations and warranties applicable to it set forth in Schedule IIIB
hereto, and by this reference incorporated herein, to the Depositor and the
Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off
Date or such other date as may be specified.

                  (d)      Each of Wilshire and IndyMac, in their capacity as
Servicers, will use its reasonable efforts to become a member of MERS in good
standing, and will comply in all material respects with the rules and procedures
of MERS in connection with the servicing of the Mortgage Loans that are
registered with MERS.

                  (e)      The Seller hereby makes the representations and
warranties set forth in Schedule IV as applicable hereto, and by this reference
incorporated herein, to the Trustee, as of the Closing Date, or the Subsequent
Transfer Date, as applicable, or if so specified therein, as of the Cut-off Date
or such other date as may be specified.

                  (f)      Upon discovery by any of the parties hereto of a
breach of a representation or warranty made pursuant to Section 2.03(e) that
materially and adversely affects the interests of the Certificateholders in any
Mortgage Loan, the party discovering such breach shall give prompt notice
thereof to the other parties. The Seller hereby covenants that within 120 days
of the earlier of its discovery or its receipt of written notice from any party
of a breach of any representation or warranty made by it pursuant to Section
2.03(e) which materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan sold by the Seller to the Depositor, it
shall cure such breach in all material respects, and if such breach is not so
cured, shall, (i) if such 120-day period expires prior to the second anniversary
of the Closing Date, remove such Mortgage Loan (a "Deleted Mortgage Loan") from
the Trust Fund and substitute in its place a Qualified Substitute Mortgage Loan,
in the manner and subject to the conditions set forth in this Section; or (ii)
repurchase the affected Mortgage Loan from the Trustee at the Repurchase Price
in the manner set forth below; provided, however, that any such substitution
pursuant to (i) above shall not be effected prior to the delivery to the Trustee
of the Opinion of Counsel required by Section 2.05 hereof, if any, and any such
substitution pursuant to (i) above shall not be effected prior to the additional
delivery to the Trustee of a Request for Release substantially in the form of
Exhibit M and the Mortgage File for any such Qualified Substitute Mortgage Loan.
The Seller shall promptly reimburse the Trustee for any actual out-of-pocket



                                       58
<PAGE>


expenses reasonably incurred by the Trustee in respect of enforcing the remedies
for such breach. With respect to any representation and warranties described in
this Section which are made to the best of a Seller's knowledge if it is
discovered by the Depositor, the Seller 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 interests of
the Certificateholders therein, notwithstanding the Seller's lack of knowledge
with respect to the substance of such representation or warranty, such
inaccuracy shall be deemed a breach of the applicable representation or
warranty.

                  With respect to any Qualified Substitute Mortgage Loan or
Loans, the Seller shall deliver to the Trustee for the benefit of the
Certificateholders the Mortgage Note, the Mortgage, the related assignment of
the Mortgage, and such other documents and agreements as are required by Section
2.01(b), with the Mortgage Note endorsed and the Mortgage assigned as required
by Section 2.01. No substitution is permitted to be made in any calendar month
after the Determination Date for such month. Scheduled Payments due with respect
to Qualified Substitute Mortgage Loans in the month of substitution shall not be
part of the Trust Fund and will be retained by the Seller on the next succeeding
Distribution Date. For the month of substitution, distributions to
Certificateholders will include the monthly payment due on any Deleted Mortgage
Loan for such month and thereafter the Seller shall be entitled to retain all
amounts received in respect of such Deleted Mortgage Loan. The Seller shall
amend the Mortgage Loan Schedule for the benefit of the Certificateholders to
reflect the removal of such Deleted Mortgage Loan and the substitution of the
Qualified Substitute Mortgage Loan or Loans and the Seller shall deliver the
amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the
Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of
this Agreement in all respects, and the Seller shall be deemed to have made with
respect to such Qualified Substitute Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties made pursuant to Section
2.03(e) with respect to such Mortgage Loan. Upon any such substitution and the
deposit to the Certificate Account of the amount required to be deposited
therein in connection with such substitution as described in the following
paragraph, the Trustee shall release the Mortgage File held for the benefit of
the Certificateholders relating to such Deleted Mortgage Loan to the Seller and
shall execute and deliver at the Seller's direction such instruments of transfer
or assignment prepared by the Seller, in each case without recourse, as shall be
necessary to vest title in the Seller, or its designee, the Trustee's interest
in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

                  For any month in which the Seller substitutes one or more
Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Trustee shall determine the amount (if any) by which the aggregate principal
balance of all such Qualified Substitute Mortgage Loans as of the date of
substitution is less than the aggregate Stated Principal Balance of all such
Deleted Mortgage Loans (after application of the scheduled principal portion of
the monthly payments due in the month of substitution). The amount of such
shortage (the "Substitution Adjustment Amount") plus an amount equal to the sum
of (i) the aggregate of any unreimbursed Advances with respect to such Deleted
Mortgage Loans and (ii) any costs and damages actually incurred and paid by or
on behalf of the Trust in connection with any breach of the representation and
warranty set forth in Schedule IV (xx) as the result of a violation of a



                                       59
<PAGE>


predatory or abusive lending law applicable to such Mortgage Loan shall be
deposited in the Certificate Account by the Seller on or before the Business Day
immediately preceding the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan became required to be repurchased
or replaced hereunder.

                  In the event that the Seller shall have repurchased a Mortgage
Loan, the Repurchase Price therefor shall be deposited in the Certificate
Account on or before the Business Day immediately preceding the Distribution
Date in the month following the month during which the Seller became obligated
hereunder to repurchase or replace such Mortgage Loan and upon such deposit of
the Repurchase Price, the delivery of the Opinion of Counsel if required by
Section 2.05 and receipt of a Request for Release in the form of Exhibit M
hereto, the Trustee shall release the related Mortgage File held for the benefit
of the Certificateholders to such Person, and the Trustee shall execute and
deliver at such Person's direction such instruments of transfer or assignment
prepared by such Person, in each case without recourse, as shall be necessary to
transfer title from the Trustee. It is understood and agreed that the obligation
under this Agreement of any Person to cure, repurchase or substitute any
Mortgage Loan as to which a breach has occurred and is continuing shall
constitute the sole remedy against such Persons respecting such breach available
to Certificateholders, the Depositor or the Trustee on their behalf.

                  The representations and warranties made pursuant to this
Section 2.03 shall survive delivery of the respective Mortgage Files to the
Trustee for the benefit of the Certificateholders.

                  SECTION 2.03 Representations and Warranties of the Depositor
                               as to the Mortgage Loans.

                  The Depositor hereby represents and warrants to the Trustee
with respect to the Mortgage Loans that, as of the Closing Date, assuming good
title has been conveyed to the Depositor, the Depositor had good title to the
Mortgage Loans and Mortgage Notes, and did not encumber the Mortgage Loans
during its period of ownership thereof, other than as contemplated by the
Agreement.

                  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.

                  SECTION 2.04 Delivery of Opinion of Counsel in Connection with
                               Substitutions.

                  Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 shall be made more than 120 days after the
Closing Date unless the Seller delivers to the Trustee an Opinion of Counsel,
which Opinion of Counsel shall not be at the expense of either the Trustee or
the Trust Fund, addressed to the Trustee, to the effect that such substitution
will not (i) result in the imposition of the tax on "prohibited transactions" on
the Trust Fund or contributions after the Startup Date, as defined in Sections
860F(a)(2) and



                                       60
<PAGE>


860G(d) of the Code, respectively, or (ii) cause any REMIC created hereunder to
fail to qualify as a REMIC at any time that any Certificates are outstanding.

                  SECTION 2.05 Execution and Delivery of Certificates.

                  The Trustee (or the Custodian) acknowledges receipt of the
items described in Section 2.02 of this Agreement and the documents identified
in the Initial Certification in the form annexed hereto as Exhibit G and,
concurrently with such receipt, has executed and delivered to or upon the order
of the Depositor, the Certificates in authorized denominations evidencing
directly or indirectly the entire ownership of the Trust Fund. The Trustee
agrees to hold the Trust Fund and exercise the rights referred to above for the
benefit of all present and future Holders of the Certificates and to perform the
duties set forth in this Agreement to the best of its ability, to the end that
the interests of the Holders of the Certificates may be adequately and
effectively protected.

                  SECTION 2.06 REMIC Matters.

                  The Preliminary Statement sets forth the designations and
"latest possible maturity date" for federal income tax purposes of all interests
created hereby. The "Startup Day" for purposes of the REMIC Provisions shall be
the Closing Date. The REMIC 1 Regular Interests shall be designated as the
"regular interests" in REMIC 1. The REMIC 2 Regular Interests shall be
designated as the "regular interests" in REMIC 2. The Class A-1, Class A-2,
Class A-3, Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6,
Class M-7, Class M-8, Class M-9, Class B-1, Class B-2, Class P, Class X-1 and
Class X-S Certificates shall be designated as the "regular interests" in REMIC
3. The Class A-RL Certificates will constitute the sole class of residual
interests in REMIC 1 and the Class A-R Certificates will represent beneficial
ownership of two residual interests, Class R-2 Interest and Class R-3 Interest,
each of which will constitute the sole class of residual interests in each of
REMIC 2 and REMIC 3, respectively. The Trustee shall not permit the creation of
any "interests" (within the meaning of Section 860G of the Code) in REMIC 1,
REMIC 2 or REMIC 3 other than the Certificates, the REMIC 1 Regular Interests or
the REMIC 2 Regular Interests. The "tax matters person" with respect to each of
REMIC 1, REMIC 2 and REMIC 3 shall be the Holder of the Class A-R Certificate
and Class A-RL Certificate at any time holding the largest Percentage Interest
thereof in the manner provided under Treasury regulations section 1.860F-4(d)
and Treasury regulations section 301.6231(a)(7)-1. The fiscal year for each
REMIC shall be the calendar year. In addition, the Class X-1 Certificateholders
shall be deemed to have entered into a contractual arrangement with the Class
A-R Certificateholders or Class A-RL Certificateholders whereby the Class A-R
Certificateholders or Class A-RL Certificateholders agree to pay to the Class
X-1 Certificateholders on each Distribution Date amounts that would, in the
absence of such contractual agreement, be distributable with respect to the
residual interest in REMIC 1, REMIC 2, and REMIC 3 pursuant to Section
4.02(b)(iv)(P) (which amounts are expected to be zero).

                  SECTION 2.07 Covenants of each Servicer.

                  Each respective Servicer hereby covenants to the Depositor and
the Trustee that no written information, certificate of an officer, statement
furnished in writing or written report prepared by such Servicer and delivered
to the Depositor, any affiliate of the Depositor or the Trustee and prepared by
such Servicer pursuant to this Agreement will contain any untrue statement of a
material fact.

                  SECTION 2.08 Conveyance of REMIC Regular Interests and
                               Acceptance of REMIC 1, REMIC 2 and REMIC 3 by the
                               Trustee; Issuance of Certificates.

                  (a)      The Depositor, concurrently with the execution and
delivery hereof, does hereby transfer, assign, set over and otherwise convey in
trust to the Trustee without recourse all the right, title and interest of the
Depositor in and to the REMIC 1 Regular Interests for the benefit of the Holder
of the REMIC 2 Regular Interests and the Holders of the Class R-2 Interest. The
Trustee acknowledges receipt of the REMIC 1 Regular Interests (each of which is
uncertificated) and declares that it holds and will hold the same in trust for
the exclusive use and benefit of the Holders of the REMIC 2 Regular Interests
and Holder of the Class R-2 Interest. The interests evidenced by the Class R-2
Interest, together with the REMIC 2 Regular Interests, constitute the entire
beneficial ownership interest in REMIC 2.

                  (b)      The Depositor, concurrently with the execution and
delivery hereof, does hereby transfer, assign, set over and otherwise convey in
trust to the Trustee without recourse all the right, title and interest of the
Depositor in and to the REMIC 2 Regular Interests for the benefit of the Holders
of the Regular Certificates and the Class R-3 Interest. The Trustee acknowledges
receipt of the REMIC 2 Regular Interests (each of which is uncertificated) and
declares that it holds and will hold the same in trust for the exclusive use and
benefit of the Holders of the Regular Certificates and of the Class R-3
Interest. The interests evidenced by the Class R-3 Interest, together with the
REMIC 3 Regular Interests, constitute the entire beneficial ownership interest
in REMIC 3.

                  (c)      In exchange for the REMIC 2 Regular Interests and,
concurrently with the assignment to the Trustee thereof, pursuant to the written
request of the Depositor executed by an officer of the Depositor, the Trustee
has executed, authenticated and delivered to or upon the order of the Depositor,
the Regular Certificates in authorized denominations evidencing (together with
the Class R-3 Interest) the entire beneficial ownership interest in REMIC 3.

                  (d)      Concurrently with (i) the assignment and delivery to
the Trustee of REMIC 1 (including the Residual Interest therein represented by
the Class A-RL Certificates) and the acceptance by the Trustee thereof, pursuant
to Section 2.01, Section 2.02 and Section 2.09(a); and (ii) the assignment and
delivery to the Trustee of REMIC 2 (including the Residual Interest therein
represented by the Class R-2 Interest) and the acceptance by the Trustee
thereof, pursuant to Section 2.09(b); and (iii) the assignment and delivery to

by the Trustee thereof, pursuant to Section 2.09(c), the Trustee, pursuant to
the written request of the Depositor executed by an officer of the Depositor,
has executed, authenticated and delivered to or upon the order of the Depositor,
the Class A-RL and the Class A-R Certificates in authorized denominations
evidencing the Class R-2 Interest and the Class R-3 Interest.

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

                  SECTION 3.01 Servicers to Service Mortgage Loans.

                  For and on behalf of the Certificateholders, each Servicer
shall service and administer the Mortgage Loans in accordance with the terms of
this Agreement and with Accepted Servicing Practices. The obligations of each of
Wilshire and IndyMac hereunder to service and administer the Mortgage Loans
shall be limited to the Wilshire Serviced Loans and IndyMac Serviced Loans,
respectively; and with respect to the duties and obligations of each Servicer,
references herein to the "Mortgage Loans" or "related Mortgage Loans" shall be
limited to the Wilshire Serviced Loans (and the related proceeds thereof and
related REO Properties), in the case Wilshire and the IndyMac Serviced Loans
(and the related proceeds thereof and related REO Properties), in the case of
IndyMac, and in no event shall any Servicer have any responsibility or liability
with respect to any of the other Mortgage Loans. Notwithstanding anything in
this Agreement, any Subservicing Agreement or the Credit Risk Management
Agreement to the contrary, neither Wilshire nor IndyMac shall have any duty or
obligation to enforce any Credit Risk Management Agreement or to supervise,
monitor or oversee the activities of the Credit Risk Manager under its Credit
Risk Management Agreement with respect to any action taken or not taken by
Wilshire or IndyMac, as applicable, pursuant to a recommendation of the Credit
Risk Manager. In connection with such servicing and administration, each
Servicer shall have full power and authority, acting alone and/or through
Subservicers as provided in Section 3.02 hereof, to do or cause to be done any
and all things that it may deem necessary or desirable in connection with such
servicing and administration, including but not limited to, the power and
authority, subject to the terms hereof (i) to execute and deliver, on behalf of
the Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided in this Agreement), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds, and (iv) to effectuate foreclosure or
other conversion of the ownership of the Mortgaged Property securing any
Mortgage Loan; provided that a Servicer shall not take any action that is
materially inconsistent with or materially prejudices the interests of the Trust
Fund or the Certificateholders in any Mortgage Loan or the rights and interests
of the Depositor, the Trustee or the Certificateholders under this Agreement
unless such action is specifically called for by the terms hereof. The Trustee
will provide a limited power of attorney to each Servicer, prepared by each
Servicer and reasonably acceptable to the Trustee, to permit each Servicer to
act on behalf of the Trustee under this Agreement. Each Servicer hereby
indemnifies the Trustee for all costs and expenses incurred by the Trustee in
connection with the negligent or willful misuse of such power of attorney. Each
Servicer shall represent and protect the interests of the Trust Fund in the same
manner as it protects its own interests in mortgage loans in its own portfolio
in any claim, proceeding or litigation regarding a Mortgage Loan. Each Servicer
further is hereby authorized and empowered in its own name or in the name of the
Subservicer, when such Servicer or the



                                       64
<PAGE>


Subservicer, as the case may be, believes it is appropriate in its best judgment
to register any Mortgage Loan on the MERS(R) System, or cause the removal from
the registration of any Mortgage Loan on the MERS(R) System, to execute and
deliver, on behalf of the Trustee and the Certificateholders or any of them, any
and all instruments of assignment and other comparable instruments with respect
to such assignment or re-recording of a Mortgage in the name of MERS, solely as
nominee for the Trustee and its successors and assigns. Any reasonable expenses
incurred in connection with the actions described in the preceding sentence or
as a result of MERS discontinuing or becoming unable to continue operations in
connection with the MERS(R) System, shall be reimbursable by the Trust Fund to
such Servicer. Notwithstanding the foregoing, subject to Section 3.05(a), the
Servicers shall not make or permit any modification, waiver or amendment of any
Mortgage Loan that would both constitute a sale or exchange of such Mortgage
Loan within the meaning of Section 1001 of the Code and any proposed, temporary
or final regulations promulgated thereunder (other than in connection with a
proposed conveyance or assumption of such Mortgage Loan that is treated as a
Principal Prepayment in Full pursuant to Section 3.10 hereof) which would cause
any of REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC. Without
limiting the generality of the foregoing, each Servicer, in its own name or in
the name of the Depositor and the Trustee, is hereby authorized and empowered by
the Depositor and the Trustee, when such Servicer believes it appropriate in its
reasonable judgment, to execute and deliver, on behalf of the Trustee, the
Depositor, the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge and all
other comparable instruments, with respect to the Mortgage Loans, and with
respect to the Mortgaged Properties held for the benefit of the
Certificateholders. Each Servicer shall prepare and deliver to the Depositor
and/or the Trustee such documents requiring execution and delivery by either or
both of them as are necessary or appropriate to enable such Servicer to service
and administer the Mortgage Loans to the extent that such Servicer is not
permitted to execute and deliver such documents pursuant to the preceding
sentence. Upon receipt of such documents and a written request signed by an
authorized officer, the Depositor and/or the Trustee shall execute such
documents and deliver them to such Servicer.

                  In accordance with the standards of the preceding paragraph,
each Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on any Mortgaged
Property (to the extent such Servicer has been notified that such taxes or
assessments have not paid by the related Mortgagor or the owner or the servicer
of the related First Mortgage Loan), which advances shall be reimbursable in the
first instance from related collections from the Mortgagors pursuant to Section
3.06, and further as provided in Section 3.08; provided, however, that each
Servicer shall be required to advance only to the extent that such advances, in
the good faith judgment of such Servicer, will be recoverable by such Servicer
out of Insurance Proceeds, Liquidation Proceeds, or otherwise out of the
proceeds of the related Mortgage Loan; and provided, further, that such payments
shall be advanced within such time period required to avoid the loss of the
Mortgaged Property by foreclosure of a tax or other lien. The costs incurred by
a Servicer, if any, in effecting the timely payments of taxes and assessments on
the Mortgaged Properties and related insurance premiums shall not, for the
purpose of calculating monthly distributions to the Certificateholders, be added



                                       65
<PAGE>


to the Stated Principal Balances of the related Mortgage Loans, notwithstanding
that the terms of such Mortgage Loans so permit.

                  Subject to the provisions of the first paragraph of this
Section, the Trustee shall execute, at the written request of a Servicer, and
furnish to such Servicer and any Subservicer such documents as are necessary or
appropriate to enable such Servicer or any Subservicer to carry out their
servicing and administrative duties hereunder, and the Trustee hereby grants to
each Servicer a power of attorney, to be completed in the form of Exhibit AA
hereto, to carry out such duties. The Trustee shall not be liable for the
actions of the Servicers or any Subservicers under such powers of attorney.

                  If the Mortgage relating to a Mortgage Loan had a lien senior
to the Mortgage Loan on the related Mortgaged Property as of the Cut-off Date,
then the related Servicer, in such capacity, may consent to the refinancing of
the prior senior lien, provided that the following requirements are met:

                  (i)      the resulting Combined Loan-to-Value Ratio of such
         Mortgage Loan is no higher than the Combined Loan-to-Value Ratio prior
         to such refinancing; and

                  (ii)     the interest rate, or, in the case of an adjustable
         rate existing senior lien, the maximum interest rate, for the loan
         evidencing the refinanced senior lien is no more than 2.0% higher than
         the interest rate or the maximum interest rate, as the case may be, on
         the loan evidencing the existing senior lien immediately prior to the
         date of such refinancing; and

                  (iii)    the loan evidencing the refinanced senior lien is not
         subject to negative amortization.

                  With respect to the Mortgage Loans, the Servicer of each
Mortgage Loan agrees that, with respect to the Mortgagors of such Mortgage
Loans, such Servicer for each Mortgage Loan shall furnish, in accordance with
the Fair Credit Reporting Act and its implementing regulations, accurate and
complete information on its borrower credit files to Equifax, Experian and Trans
Union Credit Information Company on a monthly basis.

                  SECTION 3.02 Subservicing; Enforcement of the Obligations of
                               Subservicers.

                  (a)      The Mortgage Loans may be subserviced by a
Subservicer on behalf of the related Servicer in accordance with the servicing
provisions of this Agreement, provided that the Subservicer is an approved
Fannie Mae or Freddie Mac seller/servicer in good standing. A Servicer may
perform any of its servicing responsibilities hereunder or may cause the
Subservicer to perform any such servicing responsibilities on its behalf, but
the use by such Servicer of the Subservicer shall not release such Servicer from
any of its obligations hereunder and such Servicer shall remain responsible
hereunder for all acts and omissions of the



                                       66
<PAGE>


Subservicer as fully as if such acts and omissions were those of such Servicer.
Each Servicer shall pay all fees and expenses of any Subservicer engaged by such
Servicer from its own funds.

                  Notwithstanding the foregoing, each Servicer shall be entitled
to outsource one or more separate servicing functions to a Person (each, an
"Outsourcer") that does not meet the eligibility requirements for a Subservicer,
so long as such outsourcing does not constitute the delegation of such
Servicer's obligation to perform all or substantially all of the servicing of
the related Mortgage Loans to such Outsourcer. In such event, the use by a
Servicer of any such Outsourcer shall not release such Servicer from any of its
obligations hereunder and such Servicer shall remain responsible hereunder for
all acts and omissions of such Outsourcer as fully as if such acts and omissions
were those of such Servicer, and such Servicer shall pay all fees and expenses
of the Outsourcer from such Servicer's own funds.

                  (b)      At the cost and expense of a Servicer, without any
right of reimbursement from the Depositor, Trustee, the Trust Fund, or the
Collection Account, such Servicer shall be entitled to terminate the rights and
responsibilities of its Subservicer and arrange for any servicing
responsibilities to be performed by a successor Subservicer meeting the
requirements set forth in Section 3.02(a), provided, however, that nothing
contained herein shall be deemed to prevent or prohibit such Servicer, at such
Servicer's option, from electing to service the related Mortgage Loans itself.
In the event that a Servicer's responsibilities and duties under this Agreement
are terminated pursuant to Section 7.01, and if requested to do so by the
Trustee, such Servicer shall at its own cost and expense terminate the rights
and responsibilities of its Subservicer as soon as is reasonably possible. Each
Servicer shall pay all fees, expenses or penalties necessary in order to
terminate the rights and responsibilities of its Subservicer from such
Servicer's own funds without any right of reimbursement from the Depositor,
Trustee, the Trust Fund, or the Collection Account.

                  (c)      Notwithstanding any of the provisions of this
Agreement relating to agreements or arrangements between a Servicer and its
Subservicer, a Servicer and its Outsourcer, or any reference herein to actions
taken through the Subservicer, the Outsourcer, or otherwise, no Servicer shall
be relieved of its obligations to the Depositor, Trustee or Certificateholders
and shall be obligated to the same extent and under the same terms and
conditions as if it alone were servicing and administering the related Mortgage
Loans. Each Servicer shall be entitled to enter into an agreement with its
Subservicer and Outsourcer for indemnification of such Servicer or Outsourcer,
as applicable, by such Subservicer and nothing contained in this Agreement shall
be deemed to limit or modify such indemnification.

                  For purposes of this Agreement, a Servicer shall be deemed to
have received any collections, recoveries or payments with respect to the
related Mortgage Loans that are received by a related Subservicer or Outsourcer,
as applicable, regardless of whether such payments are remitted by the
Subservicer or Outsourcer, as applicable, to such Servicer.

                  Any Subservicing Agreement and any other transactions or
services relating to the Mortgage Loans involving a Subservicer or an Outsourcer
shall be deemed to be between the Subservicer or an Outsourcer, and related
Servicer alone, and the Depositor, the Trustee and the



                                       67
<PAGE>


other Servicer shall have no obligations, duties or liabilities with respect to
a Subservicer including no obligation, duty or liability of the Depositor and
Trustee or the Trust Fund to pay a Subservicer's fees and expenses.

                  SECTION 3.03 [Reserved].

                  SECTION 3.04 Trustee to Act as Servicer.

                  (a)      In the event that any Servicer shall for any reason
no longer be a Servicer hereunder (including by reason of an Event of Default),
the Trustee or its successor shall thereupon assume all of the rights and
obligations of such Servicer hereunder arising thereafter (except that the
Trustee shall not be (i) liable for losses of such Servicer pursuant to Section
3.09 hereof or any acts or omissions of the related predecessor Servicer
hereunder, (ii) obligated to make Advances if it is prohibited from doing so by
applicable law or (iii) deemed to have made any representations and warranties
of such Servicer hereunder). Any such assumption shall be subject to Section
7.02 hereof.

                  Each Servicer shall, upon request of the Trustee, but at the
expense of such Servicer, deliver to the assuming party all documents and
records relating to each Subservicing Agreement or substitute Subservicing
Agreement and the Mortgage Loans then being serviced thereunder and hereunder by
such Servicer and an accounting of amounts collected or held by it and otherwise
use its best efforts to effect the orderly and efficient transfer of the
substitute Subservicing Agreement to the assuming party.

                  (b)      [reserved].

                  SECTION 3.05 Collection of Mortgage Loans; Collection
                               Accounts; Certificate Account; Pre-Funding
                               Account.

                  (a)      Continuously from the date hereof until the principal
and interest on all Mortgage Loans have been paid in full or such Mortgage Loans
have become Liquidated Mortgage Loans, each Servicer shall proceed in accordance
with Accepted Servicing Practices to collect all payments due under each of the
related Mortgage Loans when the same shall become due and payable to the extent
consistent with this Agreement and, consistent with such standard, with respect
to Escrow Mortgage Loans, a Servicer shall ascertain and estimate Escrow
Payments and all other charges that will become due and payable with respect to
the Mortgage Loans and the Mortgaged Properties, to the end that the
installments payable by the Mortgagors will be sufficient to pay such charges as
and when they become due and payable. Consistent with the terms of this
Agreement, each Servicer may also 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 such Servicer's
determination such waiver, modification, postponement or indulgence is not
materially adverse to the interests of the Certificateholders (taking into
account any estimated Realized Loss that might result absent such action);
provided, however, that such Servicer may not modify materially or permit any
Subservicer to modify any Mortgage Loan (unless such Mortgage Loan is in default
or, in the



                                       68
<PAGE>


judgment of such Servicer, such default is reasonably foreseeable), including
without limitation any modification that would change the Mortgage Rate, forgive
the payment of any principal or interest (unless in connection with the
liquidation of the related Mortgage Loan or except in connection with Principal
Prepayments to the extent that such reamortization is not inconsistent with the
terms of the Mortgage Loan), increase the principal balance, or extend the final
maturity date of such Mortgage Loan, and, provided however, that in no event
shall such modification reduce the interest rate on a Mortgage Loan below the
rate at which the Servicing Fee with respect to such Mortgage Loan accrues and
provided, further, that any such waiver, modification, postponement or
indulgence granted to a Mortgagor by a Servicer in connection with its servicing
of the related First Mortgage Loan shall not be considered relevant to a
determination of whether such Servicer has acted consistently with the terms and
standards of this Agreement, so long as in such Servicer's determination such
action is not materially adverse to the interests of the Certificateholders. In
the event of any such arrangement that permits the deferment of principal and
interest payment on any Mortgage Loan, the related Servicer shall make Advances
on the related Mortgage Loan in accordance with the provisions of Section 4.01
during the scheduled period in accordance with the amortization schedule of such
Mortgage Loan without modification thereof by reason of such arrangements. Each
Servicer shall not be required to institute or join in litigation with respect
to collection of any payment (whether under a Mortgage, Mortgage Note or
otherwise or against any public or governmental authority with respect to a
taking or condemnation) if it reasonably believes that enforcing the provision
of the Mortgage or other instrument pursuant to which such payment is required
is prohibited by applicable law.

                  (b)      Each Servicer shall segregate and hold all funds
collected and received pursuant to a 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 of which shall be an Eligible Account, titled
"[Servicer's name], in trust for the Holders of Credit Suisse First Boston
Mortgage Securities Corp., Home Equity Mortgage Pass-Through Certificates,
Series 2005-2" or, if established and maintained by a Subservicer on behalf of
the related Servicer, "[Subservicer's name], in trust for [Servicer's name]" or
"[Subservicer's name], as agent, trustee and/or bailee of principal and interest
custodial account for [Servicer's name], its successors and assigns, for various
owners of interest in [Servicer's name] mortgage-backed pools". Any funds
deposited in a Collection Account shall at all times be either invested in
Eligible Investments or shall be fully insured to the full extent permitted
under applicable law. Funds deposited in a Collection Account may be drawn on by
the applicable Servicer in accordance with Section 3.08.

                  Each Servicer shall deposit in the Collection Account within
two Business Days of receipt and retain therein, the following collections
remitted by Subservicers or payments received by such Servicer and payments made
by such Servicer subsequent to the Cut-off Date, other than Scheduled Payments
due on or before the Cut-off Date:

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



                                       69
<PAGE>


                  (ii)     all payments on account of interest on the Mortgage
         Loans adjusted to the per annum rate equal to the Mortgage Rate reduced
         by the related Servicing Fee Rate;

                  (iii)    all Liquidation Proceeds on the Mortgage Loans;

                  (iv)     all Insurance Proceeds on the Mortgage Loans
         including amounts required to be deposited pursuant to Section 3.09
         (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 Section 3.09);

                  (v)      all Advances made by such Servicer pursuant to
         Section 4.01;

                  (vi)     with respect to each Principal Prepayment on the
         Mortgage Loans, the Compensating Interest Payment, if any, for the
         related Prepayment Period;

                  (vii)    any amounts required to be deposited by such Servicer
         in respect of net monthly income from REO Property pursuant to Section
         3.11; and

                  (viii)   any other amounts required to be deposited hereunder
         including all collected Prepayment Charges.

                  The foregoing requirements for deposit into each Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, Ancillary Income need not be deposited
by such Servicer into such Collection Account. In addition, notwithstanding the
provisions of this Section 3.05, each Servicer may deduct from amounts received
by it, prior to deposit to the applicable Collection Account, any portion of any
Scheduled Payment representing the applicable Servicing Fee. In the event that a
Servicer shall remit any amount not required to be remitted, it may at any time
withdraw or direct the institution maintaining the related Collection Account to
withdraw such amount from such Collection Account, any provision herein to the
contrary notwithstanding. Such withdrawal or direction may be accomplished by
delivering written notice thereof to the Trustee or such other institution
maintaining such Collection Account which describes the amounts deposited in
error in such Collection Account. Each Servicer shall maintain adequate records
with respect to all withdrawals made by it pursuant to this Section. All funds
deposited in a Collection Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08.

                  (c)      On or prior to the Closing Date, the Trustee shall
establish and maintain, on behalf of the Certificateholders, the Certificate
Account. The Trustee shall, promptly upon receipt, deposit in the Certificate
Account and retain therein the following:

                  (i)      the aggregate amount remitted by each Servicer to the
         Trustee pursuant to Section 3.08(viii);

                  (ii)     any amount deposited by the Trustee pursuant to
         Section 3.05(d) in connection with any losses on Eligible Investments;
         and

                  (iii)    any other amounts deposited hereunder which are
         required to be deposited in the Certificate Account.

                  In the event that a Servicer shall remit to the Trustee any
amount not required to be remitted, it may at any time direct the Trustee to
withdraw such amount from the Certificate Account, any provision herein to the
contrary notwithstanding. Such direction may be accomplished by delivering an
Officer's Certificate to the Trustee which describes the amounts deposited in
error in the Certificate Account. All funds deposited in the Certificate Account
shall be held by the Trustee in trust for the Certificateholders until disbursed
in accordance with this Agreement or withdrawn in accordance with Section
3.08(b). In no event shall the Trustee incur liability for withdrawals from the
Certificate Account at the direction of a Servicer.

                  (d)      Each institution at which a Collection Account, the
Certificate Account or the Pre-Funding Account is maintained shall either hold
such funds on deposit uninvested or shall invest the funds therein as directed
in writing by the related Servicer (in the case of a Collection Account), the
Trustee (in the case of the Certificate Account) or the Depositor (in the case
of the Pre-Funding Account), in Eligible Investments, which shall mature not
later than (i) in the case of a Collection Account, the second Business Day
immediately preceding the related Distribution Date and (ii) in the case of the
Certificate Account and the Pre-Funding Account, the Business Day immediately
preceding the Distribution Date and, in each case, shall not be sold or disposed
of prior to its maturity. All income and gain net of any losses realized from
any such balances or investment of funds on deposit in a Collection Account
shall be for the benefit of the related Servicer as servicing compensation and
shall be remitted to it monthly as provided herein. The amount of any realized
losses in a Collection Account incurred in any such account in respect of any
such investments shall promptly be deposited by the related Servicer in the
related Collection Account. The Trustee in its fiduciary capacity shall not be
liable for the amount of any loss incurred in respect of any investment or lack
of investment of funds held in a Collection Account or the Pre-Funding Account.
All income and gain net of any losses realized from any such investment of funds
on deposit in the Certificate Account shall be for the benefit of the Trustee as
compensation and shall be remitted to it monthly as provided herein. The amount
of any realized losses in the Certificate Account incurred in any such account
in respect of any such investments shall promptly be deposited by the Trustee in
the Certificate Account. All income and gain net of any losses realized from any
such balances or investment of funds on deposit in the Pre-Funding Account shall
be for the benefit of the Depositor and shall be remitted to it monthly.

                  (e)      Each Servicer shall give notice to the Trustee, the
Seller, each Rating Agency and the Depositor of any proposed change of the
location of the related Collection Account prior to any change thereof. The
Trustee shall give notice to each Servicer, the Seller, each Rating Agency and
the Depositor of any proposed change of the location of the Certificate Account
prior to any change thereof.

                  (f)      The Trustee shall establish and maintain, on behalf
of the Certificateholders, the Pre-Funding Account. On the Closing Date, the
Depositor shall remit the Pre-Funding Amount to the Trustee for deposit in the
Pre-Funding Account. On each

Subsequent Transfer Date, upon satisfaction of the conditions for such
Subsequent Transfer Date set forth in Section 2.01(f), with respect to the
related Subsequent Transfer Agreement, the Trustee shall remit to the Depositor
the applicable Aggregate Subsequent Transfer Amount as payment of the purchase
price for the related Subsequent Mortgage Loans.

                  If any funds remain in the Pre-Funding Account on June 24,
2005, to the extent they represent interest earnings on the amounts originally
deposited into the Pre-Funding Account, the Trustee shall distribute them to the
order of the Depositor. The remaining funds in the Pre-Funding Account shall be
transferred to the Certificate Account to be included as part of principal
distributions to the Certificates, in accordance with the priorities set forth
herein, on the June 2005 Distribution Date.

                  SECTION 3.06 Establishment of and Deposits to Escrow
                               Accounts; Permitted Withdrawals from Escrow
                               Accounts; Payments of Taxes, Insurance and
                               Other Charges.

                  (a)      To the extent required by the related Mortgage Note
and not in violation of current law, the applicable Servicer shall segregate and
hold all funds collected and received pursuant to a Mortgage Loan constituting
Escrow Payments separate and apart from any of its own funds and general assets
and shall establish and maintain one or more Escrow Accounts, each of which
shall be an Eligible Account, titled, "[Servicer's name], in trust for "Credit
Suisse First Boston Mortgage Securities Corp., Home Equity Mortgage Pass-Through
Certificates, Series 2005-2 and various mortgagors" or, if established and
maintained by a Subservicer on behalf of the related Servicer, "[Subservicer's
name], in trust for [Servicer's name]" or "[Subservicer's name], as agent,
trustee and/or bailee of taxes and insurance custodial account for [Servicer's
name], its successors and assigns, for various owners of interest in [Servicer's
name] mortgage-backed pools". Funds deposited in the Escrow Account may be drawn
on by the related Servicer in accordance with Section 3.06(b). The creation of
any Escrow Account shall be evidenced by a certification in the form of Exhibit
P-1 hereto, in the case of an account established with a Servicer, or by a
letter agreement in the form of Exhibit P-2 hereto, in the case of an account
held by a depository other than a Servicer. A copy of such certification shall
be furnished to the Depositor and Trustee.

                  (b)      Each Servicer shall deposit in its Escrow Account or
Accounts on a daily basis within one Business Day of receipt and retain therein:

                  (i)      all Escrow Payments collected on account of the
         related Mortgage Loans, for the purpose of effecting timely payment of
         any such items as required under the terms of this Agreement; and

                  (ii)     all amounts representing Insurance Proceeds which are
         to be applied to the restoration or repair of any Mortgaged Property.

                  Each Servicer shall make withdrawals from the Escrow Account
only to effect such payments as are required under this Agreement, as set forth
in Section 3.06(c). Each



                                       72
<PAGE>


Servicer shall be entitled to retain any interest paid on funds deposited in the
related Escrow Account by the depository institution, other than interest on
escrowed funds required by law to be paid to the Mortgagor. To the extent
required by law, the applicable Servicer shall pay interest on escrowed funds to
the Mortgagor notwithstanding that the Escrow Account may be non-interest
bearing or that interest paid thereon is insufficient for such purposes.

                  (c)      Withdrawals from the Escrow Account or Accounts may
be made by the related Servicer only:

                  (i)      to effect timely payments of ground rents, taxes,
         assessments, water rates, mortgage insurance premiums, condominium
         charges, fire and hazard insurance premiums or other items constituting
         Escrow Payments for the related Mortgage;

                  (ii)     to reimburse such Servicer for any Servicing Advances
         made by such Servicer pursuant to this Agreement with respect to a
         related Mortgage Loan, but only from amounts received on the related
         Mortgage Loan which represent late collections of Escrow Payments
         thereunder;

                  (iii)    to refund to any Mortgagor any funds found to be in
         excess of the amounts required under the terms of the related Mortgage
         Loan;

                  (iv)     for transfer to the related Collection Account to
         reduce the principal balance of the related Mortgage Loan in accordance
         with the terms of the related Mortgage and Mortgage Note;

                  (v)      for application to restore or repair of the related
         Mortgaged Property in accordance with the procedures outlined in
         Section 3.09;

                  (vi)     to pay to such Servicer, or any Mortgagor to the
         extent required by law, any interest paid on the funds deposited in
         such Escrow Account;

                  (vii)    to clear and terminate such Escrow Account on the
         termination of this Agreement; and

                  (viii)   to remove funds inadvertently placed in the Escrow
         Account by such Servicer.

                  (d)      No later than the Closing Date, each Servicer shall
establish and maintain a sub-account of the Collection Account titled
"[Servicer's name], Simple Interest Excess Sub-Account in trust for the Holders
of Credit Suisse First Boston Mortgage Securities Corp., Home Equity Mortgage
Pass-Through Certificates, Series 2005-2". Each Servicer shall, on each
Determination Date transfer from the related Collection Account to the related
Simple Interest Excess Sub-Account all related Net Simple Interest Excess, if
any, pursuant to Section 3.08(ix), and shall maintain a record of all such
deposits.



                                       73
<PAGE>


                  (e)      Each Servicer shall withdraw amounts on deposit in
the related Simple Interest Excess Sub-Account on each Determination Date for
deposit to the related Certificate Account in an amount equal to the lesser of
(i) the amount on deposit therein, and (ii) the related Net Simple Interest
Shortfall for such Distribution Date.

                  (f)      Each Servicer shall remit to the Trustee which shall
thereupon distribute to the Class X-1 Certificateholder, based on the
information provided to it by the Servicer, 90% of the balance in the related
Simple Interest Excess Sub-Account on the Distribution Date each year occurring
in March, commencing in March 2006. Such distributions shall be deemed to be
made on a first-in, first-out basis. In addition, each Servicer shall clear and
terminate the related Simple Interest Excess Sub-Account upon the termination of
this Agreement and retain any funds remaining therein.

                  (g)      Amounts on deposit in each Simple Interest Excess
Sub-Account may be invested in Eligible Investments. All income and gain net of
any losses realized from any such balances or investment of funds on deposit in
each Simple Interest Excess Sub-Account shall be for the benefit of the related
Servicer as servicing compensation and shall be remitted to it monthly. The
amount of any net investment losses in the Simple Interest Excess Sub-Account
shall promptly be deposited by the related Servicer in such Simple Interest
Excess Sub-Account.

                  SECTION 3.07 Access to Certain Documentation and
                               Information Regarding the Mortgage Loans;
                               Inspections.

                  (a)      Each Servicer shall afford the Depositor and the
Trustee reasonable access to all records and documentation regarding the
Mortgage Loans and all accounts, insurance information and other matters
relating to this Agreement, such access being afforded without charge, but only
upon reasonable request and during normal business hours at the office
designated by such Servicer.

                  (b)      Each Servicer shall inspect the Mortgaged Properties
as often as deemed necessary by such Servicer in such Servicer's sole
discretion, to assure itself that the value of such Mortgaged Property is being
preserved. In addition, if any Mortgage Loan is more than 60 days delinquent,
each Servicer shall conduct subsequent inspections in accordance with Accepted
Servicing Practices or as may be required by the primary mortgage guaranty
insurer. Each Servicer shall keep a written or electronic report of each such
inspection.

                  SECTION 3.08 Permitted Withdrawals from the Collection
                               Accounts and Certificate Account.

                  Each Servicer may (and in the case of clause (viii) below,
shall) from time to time make withdrawals from the related Collection Account
for the following purposes:

                  (i)      to pay to such Servicer (to the extent not previously
         retained by such Servicer) the servicing compensation to which it is
         entitled pursuant to Section 3.14, and



                                       74
<PAGE>


         to pay to such Servicer, as additional servicing compensation, earnings
         on or investment income with respect to funds in or credited to such
         Collection Account;

                  (ii)     to reimburse such Servicer for unreimbursed Advances
         made by it, such right of reimbursement pursuant to this subclause (ii)
         being limited to amounts received on the Mortgage Loan(s) in respect of
         which any such Advance was made (including late recoveries of payments,
         Liquidation Proceeds and Insurance Proceeds, amounts representing
         proceeds of other insurance policies, if any, covering the related
         Mortgaged Property, rental and other income from REO Property and
         proceeds of any purchase or repurchase of the related Mortgage Loan to
         the extent deposited in the Collection Account);

                  (iii)    to reimburse such Servicer for any Nonrecoverable
         Advance;

                  (iv)     to reimburse such Servicer for (A) unreimbursed
         Servicing Advances, such Servicer's right to reimbursement pursuant to
         this clause (A) with respect to any Mortgage Loan being limited to
         amounts received on such Mortgage Loan which represent late payments of
         principal and/or interest (including, without limitation, Liquidation
         Proceeds and Insurance Proceeds, amounts representing proceeds of other
         insurance policies, if any, covering the related Mortgaged Property,
         rental and other income from REO Property and proceeds of any purchase
         or repurchase of the related Mortgage Loan with respect to such
         Mortgage Loan) respecting which any such advance was made and (B) for
         unpaid Servicing Fees as provided in Section 3.11;

                  (v)      to pay to the purchaser, with respect to each
         Mortgage Loan or property acquired in respect thereof that has been
         purchased pursuant to Section 2.02, 2.03 or 3.11, all amounts received
         thereon after the date of such purchase;

                  (vi)     to reimburse such Servicer or the Depositor for
         expenses incurred by any of them and reimbursable pursuant to Section
         6.03 hereof;

                  (vii)    to withdraw any amount deposited in such Collection
         Account and not required to be deposited therein;

                  (viii)   on or prior to the Servicer Cash Remittance Date, to
         withdraw an amount equal to the Available Funds (other than clause (vi)
         thereof) plus any related Expense Fees (other than the Servicing Fee)
         for such Distribution Date and any Prepayment Charges received in
         respect of the Mortgage Loans, subject to the collection of funds
         included in the definition of "Available Funds" and remit such amount
         to the Trustee for deposit in the Certificate Account;

                  (ix)     to deposit in the related Simple Interest Excess
         Sub-Account any amount required to be deposited therein pursuant to
         Section 3.06(d);

                  (x)      to clear and terminate such Collection Account upon
         termination of this Agreement pursuant to Section 9.01 hereof; and



                                       75
<PAGE>


                  (xi)     to invest funds in certain Eligible Investments and
         to transfer funds to another Eligible Account.

                  Each Servicer shall keep and maintain separate accounting, on
a Mortgage Loan basis for the purpose of justifying any withdrawal from the
Collection Account pursuant to such subclauses (i), (ii), (iv) and (v). Prior to
making any withdrawal from a Collection Account pursuant to subclause (iii), the
related Servicer shall deliver to the Trustee a certificate of a Servicing
Officer indicating the amount of any previous Advance determined by such
Servicer to be a Nonrecoverable Advance and identifying the related Mortgage
Loans(s), and their respective portions of such Nonrecoverable Advance.

                  The Trustee shall withdraw funds from the Certificate Account
for distributions to the Certificateholders and the Credit Risk Manager, if
applicable, in the manner specified in this Agreement (and to withhold from the
amounts so withdrawn, the amount of any taxes that it is authorized to withhold
pursuant to the last paragraph of Section 8.11). In addition, the Trustee may
from time to time make withdrawals from the Certificate Account for the
following purposes:

                  (i)      to pay to itself the Trustee Fee and any investment
         income earned for the related Distribution Date;

                  (ii)     to withdraw and return to the applicable Servicer for
         deposit to the Collection Account any amount deposited in the
         Certificate Account and not required to be deposited therein; and

                  (iii)    to clear and terminate the Certificate Account upon
         termination of this Agreement pursuant to Section 9.01 hereof.

                  SECTION 3.09 Maintenance of Hazard Insurance and Mortgage
                               Impairment Insurance; Claims; Restoration of
                               Mortgaged Property.

                  Each Servicer shall obtain and maintain a blanket policy
insuring against losses arising from fire and hazards covered under extended
coverage on all of the related Mortgage Loans, which policy shall provide
coverage in an amount equal to the amount at least equal to the lesser of (i)
the maximum insurable value of the improvements securing such Mortgage Loan and
(ii) the greater of (A) the outstanding principal balance of the Mortgage Loan
and (B) an amount such that the proceeds of such policy shall be sufficient to
prevent the Mortgagor and/or the mortgagee from becoming co-insurer. Any amounts
collected by a Servicer under any such policy relating to a Mortgage Loan (for
the avoidance of doubt, remaining after application of any such amounts to any
related First Mortgage Loan) shall be deposited in the related Collection
Account subject to withdrawal pursuant to Section 3.08. Such policy may contain
a deductible clause, in which case, in the event that there shall not have been
maintained on the related Mortgaged Property a standard hazard insurance policy,
and there shall have been a loss which would have been covered by such policy,
the related Servicer shall deposit in the related



                                       76
<PAGE>


Collection Account at the time of such loss the amount not otherwise payable
under the blanket policy because of such deductible clause which is in excess of
a deductible under a standard hazard insurance policy, such amount to be
deposited from such Servicer's funds, without reimbursement therefor. Upon
request of the Trustee, a 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
30 days' prior written notice to the Trustee. In connection with its activities
as Servicer of the Mortgage Loans, each Servicer agrees to present, on behalf of
itself, the Depositor, and the Trustee for the benefit of the
Certificateholders, claims under any such blanket policy.

                  Pursuant to Section 3.05, any amounts collected by a Servicer
under any such policies (other than amounts to be deposited in the related
Escrow Account and applied to the restoration or repair of the related Mortgaged
Property, or property acquired in liquidation of the Mortgage Loan, or to be
released to the Mortgagor, in accordance with such Servicer's normal servicing
procedures) shall be deposited in the related Collection Account (subject to
withdrawal pursuant to Section 3.08). Any costs incurred by a Servicer in
maintaining such insurance shall be recoverable by such Servicer as a Servicing
Advance out of payments by the related Mortgagor or out of Insurance Proceeds or
Liquidation Proceeds. Notwithstanding anything to the contrary in this
paragraph, each Servicer shall be required to pay the costs of maintaining any
insurance contemplated by this Section 3.09 only to the extent that such
advances, in the good faith judgment of such Servicer, will be recoverable.

                  A Servicer need not obtain the approval of the Trustee prior
to releasing any Insurance Proceeds to the Mortgagor to be applied to the
restoration or repair of the Mortgaged Property if such release is in accordance
with Accepted Servicing Practices. At a minimum, each Servicer shall comply with
the following conditions in connection with any such release of Insurance
Proceeds in excess of $10,000:

                  (i)      such Servicer shall receive satisfactory independent
         verification of completion of repairs and issuance of any required
         approvals with respect thereto;

                  (ii)     such Servicer shall take all steps necessary to
         preserve the priority of the lien of the Mortgage, including, but not
         limited to requiring waivers with respect to mechanics' and
         materialmen's liens; and

                  (iii)    pending repairs or restoration, such Servicer shall
         place the Insurance Proceeds in the related Escrow Account, if any.

                  If the Trustee is named as an additional loss payee, the
related Servicer is hereby empowered to endorse any loss draft issued in respect
of such a claim in the name of the Trustee.

                  SECTION 3.10 Enforcement of Due-on-Sale Clauses; Assumption
                               Agreements.

                  Each Servicer shall use its best efforts to enforce any
"due-on-sale" provision contained in any related Mortgage or Mortgage Note and
to deny assumption by the person to whom the Mortgaged Property has been or is
about to be sold whether by absolute conveyance or by contract of sale, and
whether or not the Mortgagor remains liable on the Mortgage and the Mortgage
Note. When the Mortgaged Property has been conveyed by the Mortgagor, the
related Servicer shall, to the extent it has knowledge of such conveyance,
exercise its rights to accelerate the maturity of such Mortgage Loan under the
"due-on-sale" clause applicable thereto, provided, however, that such Servicer
shall not exercise such rights if prohibited by law from doing so or if the
exercise of such rights would impair or threaten to impair any recovery under
the related Primary Insurance Policy, if any or, if consistent with Accepted
Servicing Practices, such Servicer believes the collections and other recoveries
in respect of such Mortgage Loans could reasonably be expected to be maximized
if the Mortgage Loan were not accelerated.

                  If a Servicer reasonably believes it is unable under
applicable law to enforce such "due-on-sale" clause or, if any of the other
conditions set forth in the last sentence of the preceding paragraph apply, such
Servicer shall enter into (i) an assumption and modification agreement with the
person to whom such property has been conveyed, pursuant to which such person
becomes liable under the Mortgage Note and the original Mortgagor remains liable
thereon or (ii) in the event such Servicer is unable under applicable law to
require that the original Mortgagor remain liable under the Mortgage Note and
such Servicer has the prior consent of the primary mortgage guaranty insurer, a
substitution of liability agreement with the purchaser of the Mortgaged Property
pursuant to which the original Mortgagor is released from liability and the
purchaser of the Mortgaged Property is substituted as Mortgagor and becomes
liable under the Mortgage Note. Notwithstanding the foregoing, a Servicer shall
not be deemed to be in default under this Section by reason of any transfer or
assumption which such Servicer reasonably believes it is restricted by law from
preventing, for any reason whatsoever. In connection with any such assumption,
no material term of the Mortgage Note, including without limitation, the
Mortgage Rate borne by the related Mortgage Note, the term of the Mortgage Loan
or the outstanding principal amount of the Mortgage Loan shall be changed.

                  Subject to each Servicer's duty to enforce any due-on-sale
clause to the extent set forth in this Section 3.10, in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, such Servicer shall prepare and
deliver or cause to be prepared and delivered to the Trustee for signature and
shall direct, in writing, the Trustee to execute the assumption agreement with
the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any



                                       78

such assumption, no material term of the Mortgage Note may be changed. Together
with each such substitution, assumption or other agreement or instrument
delivered to the Trustee for execution by it, the related Servicer shall deliver
an Officer's Certificate signed by a Servicing Officer stating that the
requirements of this Section 3.10 have been met in connection therewith. The
related Servicer shall notify the Trustee that any such substitution or
assumption agreement has been completed by forwarding to the Trustee the
original of such substitution or assumption agreement, which in the case of the
original shall be added to the related Mortgage File and 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. Any fee collected
by a Servicer for entering into an assumption, modification or substitution of
liability agreement will be retained by such Servicer as additional servicing
compensation.

                  SECTION 3.11 Realization Upon Defaulted Mortgage Loans;
                               Repurchase of Certain Mortgage Loans.

                  (a)  (i)     Each Servicer shall use reasonable efforts to
foreclose upon or otherwise comparably convert the ownership of properties
securing such of the related Mortgage Loans as come into and continue in default
and as to which no satisfactory arrangements can be made for collection of
delinquent payments. With respect to such of the Mortgage Loans as come into and
continue in default, each Servicer will decide whether to (i) foreclose upon the
Mortgaged Properties securing such Mortgage Loans, (ii) write off the unpaid
principal balance of the Mortgage Loans as bad debt, (iii) take a deed in lieu
of foreclosure, (iv) accept a short sale (a payoff of the Mortgage Loan for an
amount less than the total amount contractually owed in order to facilitate a
sale of the Mortgaged Property by the Mortgagor) or permit a short refinancing
(a payoff of the Mortgage Loan for an amount less than the total amount
contractually owed in order to facilitate refinancing transactions by the
Mortgagor not involving a sale of the Mortgaged Property), (v) arrange for a
repayment plan, or (vi) agree to a modification in accordance with this
Agreement. In connection with such decision, the related Servicer shall take
such action as (i) such Servicer would take under similar circumstances with
respect to a similar mortgage loan held for its own account for investment, (ii)
shall be consistent with Accepted Servicing Practices, (iii) such Servicer shall
determine consistently with Accepted Servicing Practices to be in the best
interest of the Trustee and Certificateholders, provided, that actions taken by
a Servicer in connection with its servicing of the related First Mortgage Loan
shall not be considered relevant to a determination of whether such Servicer has
met the standard set forth in this clause (iii), so long as in such Servicer's
determination such action is not materially adverse to the interests of the
Certificateholders and (iv) is consistent with the requirements of the insurer
under any Required Insurance Policy; provided, however, that such Servicer shall
not be required to expend its own funds in connection with any foreclosure or
towards the restoration of any property unless it shall determine in its sole
discretion (i) that such restoration and/or foreclosure will increase the
proceeds of liquidation of the related Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the related Collection Account). The related
Servicer shall be responsible for all other costs and expenses incurred by it in
any such proceedings; provided, however, that it shall be entitled to
reimbursement thereof from the liquidation proceeds with



                                       79
<PAGE>


respect to the related Mortgaged Property, as provided in the definition of
Liquidation Proceeds and as provided in Section 3.08(iv)(A).

                  (ii)     Notwithstanding anything to the contrary contained in
         this Agreement, with respect to any Mortgage Loan that is one hundred
         twenty (120) days delinquent, the related Servicer shall obtain a
         broker's price opinion with respect to the related Mortgaged Property
         and shall use all reasonable efforts to obtain a total indebtedness
         balance (including, but not limited to, unpaid principal, interest,
         escrows, taxes and expenses) for any related senior lien. The cost of
         obtaining any such broker's price opinion shall be reimbursable to the
         related Servicer as a Servicing Advance pursuant to Section 3.08(iii)
         or (iv). After obtaining the related broker's price opinion, the
         related Servicer will determine whether any Significant Net Recovery is
         possible through foreclosure proceedings or other liquidation of the
         related Mortgaged Property. If the related Servicer determines that (x)
         no Significant Net Recovery is possible or (y) the potential Net
         Recoveries are anticipated to be an amount, determined by the related
         Servicer in its good faith judgment and in light of other mitigating
         circumstances, that is insufficient to warrant proceeding through
         foreclosure or other liquidation of the related Mortgaged Property, it
         may, at its discretion, charge off such delinquent Mortgage Loan in
         accordance with subsections (a)(iii) and (a)(iv) below.

                  (iii)    With respect to any Mortgage Loan, if the related
         Servicer determines based on the broker's price opinion obtained under
         paragraph (a)(ii) above and other relevant considerations that (x) no
         Significant Net Recovery is possible through foreclosure proceedings or
         other liquidation of the related Mortgaged Property or (y) the
         potential Net Recoveries are anticipated to be an amount, determined by
         the related Servicer in its good faith judgment and in light of other
         mitigating circumstances, that is insufficient to warrant proceeding
         through foreclosure or other liquidation of the related Mortgaged
         Property, it will be obligated to charge off the related Mortgage Loan
         at the time such Mortgage Loan becomes 180 days delinquent. Once a
         Mortgage Loan has been charged off, the related Servicer will
         discontinue making Advances, the related Servicer will not be entitled
         to any additional servicing compensation (except as described in
         paragraphs(a)(ii) or (a)(iv) of this Section 3.11), the Charged Off
         Loan will give rise to a Realized Loss, and the related Servicer will
         follow the procedures described in paragraph (a)(iv) below. If the
         related Servicer determines that (x) a Significant Net Recovery is
         possible through foreclosure proceedings or other liquidation of the
         Mortgaged Property and (y) the potential Net Recoveries are anticipated
         to be an amount, determined by the related Servicer in its good faith
         judgment and in light of other mitigating circumstances, that is
         sufficient to warrant proceeding through foreclosure or other
         liquidation of the related Mortgaged Property, such Servicer may
         continue to make Advances or Servicing Advances on the related Mortgage
         Loan that has become 180 days delinquent and, will notify the Credit
         Risk Manager of that decision.

                  (iv)     (A) With respect to any IndyMac Serviced Loan that
         becomes a Charged Off Loan, IndyMac shall notify Wilshire of its
         decision to charge off such Mortgage Loan and the servicing of such
         IndyMac Serviced Loan will be transferred to Wilshire,



                                       80
<PAGE>


         such transfer to be initiated by IndyMac on the 15th day of the month
         (or if the 15th of the month is not a Business Day, the next Business
         Day) following the month in which such IndyMac Serviced Loan becomes a
         Charged Off Loan and may be serviced, at Wilshire's discretion, using
         Wilshire Special Servicing as provided in paragraph (iv)(B) below.
         Immediately upon transfer of any IndyMac Serviced Loan to Wilshire,
         IndyMac shall be reimbursed for all unreimbursed Advances and Servicing
         Advances (including any trailing expenses incurred prior to but
         invoiced after the date servicing is transferred to Wilshire, so long
         as IndyMac notifies the Trustee of such trailing expenses within 90
         days of the date of such transfer) and unpaid Servicing Fees relating
         to such transferred Mortgage Loan out of funds on deposit in the
         Collection Account. IndyMac shall provide an Officer's Certificate to
         the Trustee no later than the related Servicer Remittance Date
         evidencing the amount to be reimbursed pursuant to the previous
         sentence with respect to any Mortgage Loans transferred by IndyMac to
         Wilshire. IndyMac shall notify the Trustee of any IndyMac Serviced Loan
         that is transferred to Wilshire. IndyMac shall provide servicing
         information on such transferred Mortgage Loans as reasonably requested
         by Wilshire including, but not limited to, an electronic data tape
         containing the fields set forth in Exhibit T hereto, and an electronic
         file or hard copy containing collection comments, outstanding advance
         balances, payment histories, and hardcopies of any imaged files.
         IndyMac shall be responsible for any other reasonable actions required
         by Accepted Servicing Practices relating to the transfer of servicing
         and the charging off of such Mortgage Loans. All costs of such transfer
         of the electronic data tape and files relating to IndyMac Serviced
         Loans shall be paid by IndyMac. IndyMac shall not be responsible for
         Wilshire's boarding costs of such transferred Mortgage Loans. Wilshire
         shall not be responsible for the reimbursement of any Advance or
         Servicing Advance on a transferred Mortgage Loan.

                  (B)      Any (x) Wilshire Serviced Loan that becomes a Charged
         Off Loan and (y) IndyMac Serviced Loan that becomes a Charged Off Loan
         and is transferred to Wilshire pursuant to paragraph (iv)(A) above may
         continue to be serviced by Wilshire for the Certificateholders using
         Wilshire Special Servicing. Wilshire will accrue, but not be entitled
         to any Servicing Fees and reimbursement of expenses in connection with
         such Charged Off Loans, except to the extent of funds available from
         the aggregate amount of recoveries on all Charged Off Loans. Such
         aggregate recovery amounts on Charged Off Loans shall be paid to
         Wilshire first, as reimbursement of any outstanding and unpaid
         expenses, and second, as any accrued and unpaid Servicing Fees.
         Wilshire will only be entitled to previously accrued Servicing Fees and
         expenses on any such Charged Off Loans. Wilshire will not be entitled
         to receive any future unaccrued Servicing Fees or expenses from
         collections on such Charged Off Loans. Any Charged Off Loan serviced by
         Wilshire using Wilshire Special Servicing shall be so serviced until
         the Release Date described below. Any Net Recoveries on such Charged
         Off Loans received prior to the Release Date will be included in
         Available Funds.

                  On the date (the "Release Date") which is no more than six
months after the date on which Wilshire begins servicing any Charged Off Loans
using Wilshire Special Servicing, unless specific Net Recoveries are anticipated
by Wilshire on a particular Charged Off Loan (in



                                       81
<PAGE>


which case the Release Date will be delayed until all such specific anticipated
Net Recoveries are received), such Charged Off Loan will be released from the
Trust Fund, will no longer be an asset of any REMIC, and will be transferred to
the Class X-2 Certificateholders, without recourse, and thereafter (i) those
Holders will be entitled to any amounts subsequently received in respect of any
such Released Loans, (ii) the Majority in Interest Class X-2 Certificateholder
may designate any servicer to service any such Released Loan and (iii) the
Majority in Interest Class X-2 Certificateholder may sell any such Released Loan
to a third party. Notwithstanding the previous sentence, if at any time after a
Mortgage Loan has been Charged Off and prior to six months after the date on
which Wilshire begins servicing such Charged Off Loan using Wilshire Special
Servicing, Wilshire determines that there will not be any Net Recoveries on such
Charged Off Loan under any circumstances, Wilshire may release such Charged Off
Loan to the Majority in Interest Class X-2 Certificateholder in accordance with
the provisions set forth in the previous sentence.

                  Notwithstanding the foregoing, the procedures described above
in this subsection 3.11(a)(iv) relating to the treatment of Charged Off Loans
may be modified at any time at the discretion of the Majority in Interest Class
X-1 Certificateholder, with the consent of Wilshire, which consent shall not be
unreasonably withheld; provided, however, that in no event shall the Majority in
Interest Class X-1 Certificateholder change the fee structure relating to
Charged Off Loans in a manner that would cause fees to be paid to Wilshire other
than from recoveries on Charged Off Loans.

                  The Trustee shall track collections received by Wilshire on
any Charged Off Loans based upon loan level data provided to the Trustee by
Wilshire on each Servicer Data Remittance Date in a report in the form of
Exhibit U hereto, identifying the Charged Off Loans as of the related Due Period
that Wilshire will continue to service until the related Release Date using
Wilshire Special Servicing. On each Distribution Date, the Trustee shall verify,
based on the recovery and expense information provided by Wilshire on the
related Servicer Data Remittance Date, (i) the aggregate amount of accrued and
unpaid Servicing Fees to be paid to Wilshire and expenses to be reimbursed to
Wilshire on such Charged Off Loans as of the related Due Period and (ii) the
amount of Net Recoveries on such Charged Off Loans for such Distribution Date.
The Trustee shall be entitled to rely, without independent verification, on the
loan level data provided by Wilshire that identifies the recovery amounts and
the outstanding and unpaid expenses on any Charged Off Loan in order to verify
the amount in clause (ii) of the previous sentence. The Trustee will be
responsible for independently verifying the aggregate amount of accrued and
unpaid Servicing Fees described in clause (i) of the second preceding sentence
to be paid to Wilshire.

                  (v)      Notwithstanding anything to the contrary contained in
         this Agreement, in connection with a foreclosure or acceptance of a
         deed in lieu of foreclosure, in the event the related Servicer has
         reasonable cause to believe that a Mortgaged Property is contaminated
         by hazardous or toxic substances or wastes, or if the Trustee otherwise
         requests, an environmental inspection or review of such Mortgaged
         Property conducted by a qualified inspector shall be arranged for by
         the such Servicer. Upon completion of the inspection, the related
         Servicer shall promptly provide the Trustee with a written



                                       82
<PAGE>


         report of environmental inspection. It is understood by the parties
         hereto that any cost related to such inspection shall be advanced by
         the related Servicer and will be deemed a Servicing Advance in
         accordance with the provisions of Section 3.08 hereof.

                  (vi)     In the event the environmental inspection report
         indicates that the Mortgaged Property is contaminated by hazardous or
         toxic substances or wastes, the related Servicer shall not proceed with
         foreclosure or acceptance of a deed in lieu of foreclosure if the
         estimated costs of the environmental clean up, as estimated in the
         environmental inspection report, together with the Servicing Advances
         made by such Servicer and the estimated costs of foreclosure or
         acceptance of a deed in lieu of foreclosure exceeds the estimated value
         of the Mortgaged Property. If however, the aggregate of such clean up
         and foreclosure costs and Servicing Advances are less than or equal to
         the estimated value of the Mortgaged Property, then the related
         Servicer may, in its reasonable judgment and in accordance with
         Accepted Servicing Practices, choose to proceed with foreclosure or
         acceptance of a deed in lieu of foreclosure and such Servicer shall be
         reimbursed for all reasonable costs associated with such foreclosure or
         acceptance of a deed in lieu of foreclosure and any related
         environmental clean up costs, as applicable, from the related
         Liquidation Proceeds, or if the Liquidation Proceeds are insufficient
         to fully reimburse such Servicer, such Servicer shall be entitled to be
         reimbursed from amounts in the related Collection Account pursuant to
         Section 3.08 hereof. In the event the related Servicer does not proceed
         with foreclosure or acceptance of a deed in lieu of foreclosure
         pursuant to the first sentence of this paragraph, such Servicer shall
         be reimbursed for all Servicing Advances made with respect to the
         related Mortgaged Property from the related Collection Account pursuant
         to Section 3.08 hereof, such Servicer shall have no further obligation
         to service such Mortgage Loan under the provisions of this Agreement
         and the related Mortgage Loan will be transferred to Wilshire in
         accordance with paragraph (iv) above.

                  (b)      With respect to any REO Property, the deed or
certificate of sale shall be taken in the name of JPMorgan Chase Bank, N.A. (or
in the case of a successor trustee, the name of such successor trustee), the
Trustee for the benefit of the Certificateholders of Home Equity Mortgage Trust
Series 2005-2, or its nominee, on behalf of the Certificateholders. The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee hereunder and not in its individual capacity. Pursuant to its efforts to
sell such REO Property, the related Servicer shall in accordance with Accepted
Servicing Practices manage, conserve, protect and operate each REO Property for
the purpose of its prompt disposition and sale. The related Servicer, either
itself or through an agent selected by such Servicer, shall manage, conserve,
protect and operate the REO Property in the same manner that it manages,
conserves, protects and operates other foreclosed property for its own account,
and in the same manner that similar property in the same locality as the REO
Property is managed. The related Servicer may rent such property, as such
Servicer deems to be in the best interest of the Trustee and the
Certificateholders for the period prior to the sale of such REO Property on such
terms and conditions and for such periods as such Servicer deems to be in the
best interest of the Trustee and the Certificateholders. The related Servicer
shall furnish to the Trustee on or before each Distribution Date a statement
with respect to any REO Property covering the liquidation thereof during the
previous calendar



                                       83
<PAGE>


month. That statement shall be accompanied by such other information as the
Trustee shall reasonably request and which is necessary to enable the Trustee to
comply with the reporting requirements of the REMIC Provisions. The net monthly
rental income, if any, from such REO Property shall be deposited in the related
Collection Account no later than the close of business on each Determination
Date. The related Servicer shall perform the tax reporting and withholding
required by Sections 1445 and 6050J of the Code with respect to foreclosures and
abandonments, the tax reporting required by Section 6050H of the Code with
respect to the receipt of mortgage interest from individuals and any tax
reporting required by Section 6050P of the Code with respect to the cancellation
of indebtedness by certain financial entities, by preparing such tax and
information returns as may be required, in the form required, and delivering the
same to the Trustee for filing. Notwithstanding the previous sentence, with
respect to any IndyMac Serviced Loan that becomes a Charged Off Loan and is
transferred to Wilshire pursuant to Section 3.11(a)(iv)(A) above, IndyMac shall
not file a Form 1099C or other tax report relating to the forgiveness of debt of
the related Mortgagor.

                  To the extent consistent with Accepted Servicing Practices,
the related Servicer shall also maintain on each REO Property fire and hazard
insurance with extended coverage in amount which is equal to the outstanding
principal balance of the related Mortgage Loan (as reduced by any amount applied
as a reduction of principal at the time of acquisition of the REO Property),
liability insurance and, to the extent required and available under the Flood
Disaster Protection Act of 1973, as amended, flood insurance in the amount
required above. Any costs incurred by a Servicer in maintaining such insurance
shall be recoverable by such Servicer as a Servicing Advance out of payments by
the related Mortgagor or out of Insurance Proceeds or Liquidation Proceeds.
Notwithstanding anything to the contrary in this paragraph, each Servicer shall
be required to pay the costs of maintaining any insurance contemplated by this
Section 3.11(b) only to the extent that such advances, in the good faith
judgment of such Servicer, will be recoverable.

                  (c)      In the event that the Trust Fund acquires any
Mortgaged Property as aforesaid or otherwise in connection with a default or
imminent default on a Mortgage Loan, the related Servicer shall dispose of such
Mortgaged Property prior to three years after the end of the calendar year of
its acquisition by the Trust Fund unless (i) the Trustee shall have been
supplied with an Opinion of Counsel to the effect that the holding by the Trust
Fund of such Mortgaged Property subsequent to such three-year period will not
result in the imposition of taxes on "prohibited transactions" of any REMIC
hereunder as defined in section 860F of the Code or cause any REMIC hereunder 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 Mortgaged Property (subject
to any conditions contained in such Opinion of Counsel) or (ii) the applicable
Servicer shall have applied for, prior to the expiration of such three-year
period, an extension of such three-year period in the manner contemplated by
Section 856(e)(3) of the Code, in which case the three-year period shall be
extended by the applicable extension period. The applicable Servicer shall be
entitled to be reimbursed from the Collection Account, as a Servicing Advance,
for any costs incurred in obtaining such Opinion of Counsel. Notwithstanding any
other provision of this Agreement, no Mortgaged Property acquired by the Trust
Fund shall be rented (or allowed to continue to be rented) or otherwise used for
the production of income by or on



                                       84
<PAGE>


behalf of the Trust Fund in such a manner or pursuant to any terms that would
(i) cause such Mortgaged Property to fail to qualify as "foreclosure property"
within the meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC
hereunder to the imposition of any federal, state or local income taxes on the
income earned from such Mortgaged Property under Section 860G(c) of the Code or
otherwise, unless the related Servicer has agreed to indemnify and hold harmless
the Trust Fund with respect to the imposition of any such taxes.

                  In the event of a default on a Mortgage Loan one or more of
whose obligor is not a United States Person, as that term is defined in Section
7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a
deed in lieu of foreclosure (together, "foreclosure") in respect of such
Mortgage Loan, the related Servicer will cause compliance with the provisions of
Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary
to assure that no withholding tax obligation arises with respect to the proceeds
of such foreclosure except to the extent, if any, that proceeds of such
foreclosure are required to be remitted to the obligors on the Mortgage Loan.

                  (d)      The decision of a Servicer to foreclose on a
defaulted Mortgage Loan shall be subject to a determination by such Servicer
that the proceeds of such foreclosure would exceed the costs and expenses of
bringing such a proceeding. The income earned from the management of any REO
Properties, net of reimbursement to such Servicer for expenses incurred
(including any property or other taxes) in connection with such management and
net of applicable accrued and unpaid Servicing Fees, and unreimbursed Advances
and Servicing Advances, shall be applied to the payment of principal and
interest on the related defaulted Mortgage Loans (with interest accruing as
though such Mortgage Loans were still current) and all such income shall be
deemed, for all purposes in this Agreement, to be payments on account of
principal and interest on the related Mortgage Notes and shall be deposited into
the related Collection Account. To the extent the net income received during any
calendar month is in excess of the amount attributable to amortizing principal
and accrued interest at the related Mortgage Rate on the related Mortgage Loan
for such calendar month, such excess shall be considered to be a partial
prepayment of principal of the related Mortgage Loan.

                  No Servicer shall acquire any Mortgaged Property on behalf of
any REMIC created hereunder in connection with a default or imminent default on
a Foreclosure Restricted Loan, if acquiring title to the Mortgaged Property
underlying the loan would cause the adjusted basis, for federal income tax
purposes, of these Mortgaged Properties owned by the related REMIC after
foreclosure, along with any other assets owned by the related REMIC other than
"qualified mortgages" and "permitted investments" within the meaning of Section
860G of the Code, to exceed 0.75% of the adjusted basis of the assets of the
related REMIC. If the adjusted basis of such Mortgaged Properties in
foreclosure, along with any other assets owned by the related REMIC, other than
"qualified mortgages" and "permitted



                                       85
<PAGE>


investments" with the meaning of Section 860G of the Code, exceed 1.0% of the
adjusted basis of the assets of the related REMIC immediately after the
distribution of principal and interest on any Distribution Date, Wilshire will
dispose of enough of such Mortgaged Properties in foreclosure, for cash or
otherwise, so that the adjusted basis of such Mortgaged Properties in
foreclosure, along with any other assets owned by the related REMIC, other than
"qualified mortgages" and "permitted investments" within the meaning of Section
860G of the Code, will be less than 1.0% of the adjusted basis of the assets of
the related REMIC. With respect to each Servicer, the foregoing percentage
limitations will apply only to the Mortgage Loans serviced by such Servicer.

                  (e)      The proceeds from any liquidation of a Mortgage Loan,
as well as any income from an REO Property, if applicable, will be applied in
the following order of priority: first, to reimburse the related Servicer for
any related unreimbursed Servicing Advances and Servicing Fees; second, to
reimburse such Servicer for any unreimbursed Advances; third, to reimburse the
related Collection Account for any Nonrecoverable Advances (or portions thereof)
that were previously withdrawn by such Servicer pursuant to Section 3.08(iii)
that related to such Mortgage Loan; fourth, to accrued and unpaid interest (to
the extent no Advance has been made for such amount or any such Advance has been
reimbursed) on the Mortgage Loan or related REO Property, at the per annum rate
equal to the related Mortgage Rate reduced by the related Servicing Fee Rate, to
the Due Date occurring in the month in which such amounts are required to be
distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess
proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be
retained by the related Servicer as additional servicing compensation pursuant
to Section 3.14.

                  (f)      [reserved].

                  (g)      The Majority in Interest Class X-2 Certificateholder,
at its option, may (but is not obligated to) repurchase from the Trust Fund, (a)
any related Mortgage Loan that is delinquent in payment by three or more
Scheduled Payments or (b) any related Mortgage Loan with respect to which there
has been initiated legal action or other proceedings for the foreclosure of the
related Mortgaged Property either judicially or non-judicially. If it elects to
make any such repurchase, the Majority in Interest Class X-2 Certificateholder
shall repurchase such Mortgage Loan with its own funds at a price equal to the
Repurchase Price for such Mortgage Loan. The Majority in Interest Class X-2
Certificateholder may designate any servicer to service any such Mortgage Loan
purchased from the Trust.

                  SECTION 3.12 Trustee to Cooperate; Release of Mortgage Files.

                  Upon the payment in full of any Mortgage Loan, or the receipt
by a Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, such Servicer will immediately notify the
Trustee (or the Custodian, as the case may be) by delivering, or causing to be
delivered a "Request for Release" substantially in the form of Exhibit M. Upon
receipt of such request, the Trustee (or the Custodian, as the case may be)
shall within three Business Days release the related Mortgage File to the
related Servicer, and the Trustee shall within three Business Days of such
Servicer's direction execute and deliver to such Servicer the request for
reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage in each case provided by such
Servicer, together with the Mortgage Note with written evidence of cancellation
thereon. Each Servicer is authorized to cause the removal from the registration
on the MERS(R) System of such Mortgage, if applicable, and to execute and
deliver, on behalf of the Trustee and the Certificateholders or any of them, any
and all instruments of satisfaction or cancellation or of



                                       86
<PAGE>


partial or full release. Expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the related
Mortgagor to the extent permitted by law and otherwise shall constitute a
Servicing Advance. From time to time and as shall be appropriate for the
servicing or foreclosure of any Mortgage Loan, including for such purpose,
collection under any policy of flood insurance, any fidelity bond or errors or
omissions policy, or for the purposes of effecting a partial release of any
Mortgaged Property from the lien of the Mortgage or the making of any
corrections to the Mortgage Note or the Mortgage or any of the other documents
included in the Mortgage File, the Trustee shall, within three Business Days of
delivery to the Trustee (or the Custodian, as the case may be) of a Request for
Release in the form of Exhibit M signed by a Servicing Officer, release the
Mortgage File to the related Servicer. Subject to the further limitations set
forth below, the related Servicer shall cause the Mortgage File or documents so
released to be returned to the Trustee (or the Custodian, as the case may be)
when the need therefor by such Servicer no longer exists, unless the Mortgage
Loan is liquidated and the proceeds thereof are deposited in the related
Collection Account, in which case such Servicer shall deliver to the Trustee (or
the Custodian, as the case may be) a Request for Release in the form of Exhibit
M, signed by a Servicing Officer.

                  If a Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this Agreement,
such Servicer shall, if applicable, deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents (which, if acceptable by the related court,
may be copies) necessary to effectuate such foreclosure or any legal action
brought to obtain judgment against the Mortgagor on the Mortgage Note or the
Mortgage or to obtain a deficiency judgment or to enforce any other remedies or
rights provided by the Mortgage Note or the Mortgage or otherwise available at
law or in equity.

                  SECTION 3.13 Documents, Records and Funds in Possession of a
                               Servicer to be Held for the Trustee.

                  Notwithstanding any other provisions of this Agreement, each
Servicer shall transmit to the Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the related Servicer from time to time required to be delivered to
the Trustee pursuant to the terms hereof and shall account fully to the Trustee
for any funds received by such Servicer or which otherwise are collected by such
Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any
Mortgage Loan. All Mortgage Files and funds collected or held by, or under the
control of, a Servicer in respect of any Mortgage Loans, whether from the
collection of principal and interest payments or from Liquidation Proceeds,
including but not limited to, any funds on deposit in a Collection Account,
shall be held by the related Servicer for and on behalf of the Trustee and shall
be and remain the sole and exclusive property of the Trustee, subject to the
applicable provisions of this Agreement. Each Servicer also agrees that it shall
not create, incur or subject any Mortgage File or any funds that are deposited
in the related Collection Account, Certificate Account or any related Escrow
Account, or any funds that otherwise are or may become due or payable to the
Trustee for the benefit of the Certificateholders, to any claim, lien (other
than the lien of a related First Mortgage Loan), security interest, judgment,
levy, writ of attachment or other



                                       87
<PAGE>


encumbrance, or assert by legal action or otherwise any claim or right of setoff
against any Mortgage File or any funds collected on, or in connection with, a
Mortgage Loan, except, however, that such Servicer shall be entitled to set off
against and deduct from any such funds any amounts that are properly due and
payable to such Servicer under this Agreement.

                  SECTION 3.14 Servicing Fee.

                  As compensation for its services hereunder, each Servicer
shall be entitled to withdraw from the Collection Account or to retain from
interest payments on the related Mortgage Loans the amount of its Servicing Fee
for each Mortgage Loan, less any amounts in respect of its Servicing Fee payable
by such Servicer pursuant to Section 3.05(b)(vi). The Servicing Fee is limited
to, and payable solely from, the interest portion of such Scheduled Payments
collected by the related Servicer or as otherwise provided in Section 3.08.

                  Additional servicing compensation in the form of Ancillary
Income shall be retained by the related Servicer. Each Servicer shall be
required to pay all expenses incurred by it in connection with its servicing
activities hereunder (including the payment of any expenses incurred in
connection with any Subservicing Agreement entered into pursuant to Section
3.02) and shall not be entitled to reimbursement thereof except as specifically
provided for in this Agreement.

                  SECTION 3.15 Access to Certain Documentation.

                  Each Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of Subordinate
Certificates and the examiners and supervisory agents of the OTS, the FDIC and
such other authorities, access to the documentation regarding the related
Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such
access shall be afforded without charge, but only upon reasonable and prior
written request and during normal business hours at the offices designated by
such Servicer. Nothing in this Section shall limit the obligation of any
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Mortgagors and the failure of such Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section. Nothing in this Section 3.15 shall require any Servicer
to collect, create, collate or otherwise generate any information that it does
not generate in its usual course of business.

                  SECTION 3.16 Annual Statement as to Compliance.

                  Not later than the earlier of (a) March 15 of each calendar
year (other than the calendar year during which the Closing Date occurs) or (b)
with respect to any calendar year during which the Depositor's annual report on
Form 10-K is required to be filed in accordance with the Exchange Act and the
rules and regulations of the Commission, 15 calendar days before the date on
which the Depositor's annual report on Form 10-K is required to be filed in
accordance with the Exchange Act and the rules and regulations of the Commission
(or, in each case, if such day is not a Business Day, the immediately preceding
Business Day), each Servicer shall deliver to the Depositor, the Rating Agencies
and the Trustee an Officer's Certificate



                                       88
<PAGE>


stating, as to the signer thereof, that (i) a review of the activities of such
Servicer during the preceding calendar year and of the performance of such
Servicer under this Agreement has been made under such officer's supervision,
and (ii) to the best of such officer's knowledge, based on such review, such
Servicer has fulfilled all its obligations under this Agreement throughout such
year, or, if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof and the action being taken by such Servicer to cure such default.

                  SECTION 3.17 Annual Independent Public Accountants' Servicing
                               Statement; Financial Statements.

                  Not later than the earlier of (a) March 15 of each calendar
year (other than the calendar year during which the Closing Date occurs) or (b)
with respect to any calendar year during which the Depositor's annual report on
Form 10-K is required to be filed in accordance with the Exchange Act and the
rules and regulations of the Commission, 15 calendar days before the date on
which the Depositor's annual report on Form 10-K is required to be filed in
accordance with the Exchange Act and the rules and regulations of the Commission
(or, in each case, if such day is not a Business Day, the immediately preceding
Business Day), each Servicer at its expense shall cause a nationally or
regionally recognized firm of independent public accountants (who may also
render other services to such Servicer, the Seller or any affiliate thereof)
which is a member of the American Institute of Certified Public Accountants to
furnish a statement to the Trustee and the Depositor to the effect that such
firm has examined certain documents and records relating to the servicing of
mortgage loans which such Servicer is servicing, which may include the related
Mortgage Loans or similar mortgage loans, and that, on the basis of such
examination, conducted substantially in compliance with the Uniform Single
Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved
Title II Approved Mortgagees and Loan Correspondent Programs, nothing has come
to their attention which would indicate that such servicing has not been
conducted in compliance with Accepted Servicing Practices, except for (a) such
exceptions as such firm shall believe to be immaterial, and (b) such other
exceptions as shall be set forth in such statement. In addition, each Servicer
shall disclose to such firm all significant deficiencies relating to such
Servicer's compliance with the minimum servicing standards set forth in this
Agreement. In rendering such statement, such firm may rely, as to matters
relating to direct servicing of mortgage loans by Subservicers, upon comparable
statements for examinations conducted substantially in compliance with the
Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for
HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs
(rendered within one year of such statement) of independent public accountants
with respect to the related Subservicer. Copies of such statement shall be
provided by the Trustee to any Certificateholder upon request at the related
Servicer's expense, provided such statement is delivered by such Servicer to the
Trustee.

                  SECTION 3.18 Maintenance of Fidelity Bond and Errors and
                               Omissions Insurance.

                  Each Servicer shall maintain with responsible companies, at
its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance
Policy, with broad coverage on all



                                       89
<PAGE>


officers, employees or other persons acting in any capacity requiring such
persons to handle funds, money, documents or papers relating to the related
Mortgage Loans ("Servicer Employees"). The amount of coverage under any such
Fidelity Bond and Errors and Omissions Insurance Policy shall be at least equal
to the coverage maintained by the related Servicer in order to be acceptable to
Fannie Mae or Freddie Mac to service loans for it or otherwise in an amount as
is commercially available at a cost that is generally not regarded as excessive
by industry standards. No provision of this Section 3.18 requiring such Fidelity
Bond and Errors and Omissions Insurance Policy shall diminish or relieve a
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. Upon the request of
the Trustee, the related Servicer shall cause to be delivered to the Trustee a
certificate of insurance of the insurer and the surety including a statement
from the surety and the insurer that such fidelity bond and insurance policy
shall in no event be terminated or materially modified without 30 days' prior
written notice to the Trustee.

                  SECTION 3.19 Duties of the Credit Risk Manager.

                  The Depositor appoints The Murrayhill Company as Credit Risk
Manager. For and on behalf of the Depositor, and the Trustee, the Credit Risk
Manager will provide the Depositor with reports and recommendations concerning
Mortgage Loans that are past due, as to which there has been commencement of
foreclosure, as to which there has been forbearance in exercise of remedies
which are in default, as to which obligor is the subject of bankruptcy,
receivership, or an arrangement of creditors, or as to which have become REO
Properties. Such reports and recommendations will be based upon information
provided to the Credit Risk Manager pursuant to the Credit Risk Management
Agreements and the Credit Risk Manager shall look solely to the related Servicer
for all information and data (including loss and delinquency information and
data) and loan level information and data relating to the servicing of the
Mortgage Loans. If the Credit Risk Manager is no longer able to perform its
duties hereunder, the Depositor shall terminate the Credit Risk Manager and
cause the appointment of a successor Credit Risk Manager. Upon any termination
of the Credit Risk Manager or the appointment of a successor Credit Risk
Manager, the Depositor shall give written notice thereof to the Seller, the
Servicers, the Trustee and each Rating Agency. Notwithstanding the foregoing,
the termination of the Credit Risk Manager pursuant to this Section 3.19 shall
not become effective until the appointment of a successor Credit Risk Manager.

                  SECTION 3.20 Limitation Upon Liability of the Credit Risk
                               Manager.

                  Neither the Credit Risk Manager, nor any of the directors,
officers, employees or agents of the Credit Risk Manager, shall be under any
liability to the Trustee, the Certificateholders or the Depositor for any action
taken or for refraining from the taking of any action in good faith pursuant to
this Agreement, in reliance upon information provided by a Servicer under the
Credit Risk Management Agreements or of errors in judgment; provided, however,
that this provision shall not protect the Credit Risk Manager or any such person
against liability that would otherwise be imposed by reason of willful
malfeasance, bad faith or gross negligence in its performance of its duties
under this Agreement or the Credit Risk Manager



                                       90
<PAGE>


Agreements. The Credit Risk Manager and any director, officer, employee or agent
of the Credit Risk Manager 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, and may rely in good faith upon the accuracy of information
furnished by any Servicer pursuant to the Credit Risk Management Agreements in
the performance of its duties thereunder and hereunder.

                  SECTION 3.21 Advance Facility.

                  (a)      Wilshire and IndyMac are each hereby authorized to
enter into a financing or other facility (any such arrangement, an "Advance
Facility") under which (1) Wilshire or IndyMac, as applicable, assigns or
pledges to another Person (an "Advancing Person") such Servicer's rights under
this Agreement to be reimbursed for any Advances or Servicing Advances and/or
(2) an Advancing Person agrees to fund some or all Advances and/or Servicing
Advances required to be made by Wilshire or IndyMac, as applicable, pursuant to
this Agreement. No consent of the Trustee, Certificateholders or any other party
is required before Wilshire or IndyMac, as applicable, may enter into an Advance
Facility; PROVIDED, HOWEVER, that the consent of the Trustee (which consent
shall not be unreasonably withheld) shall be required before Wilshire may cause
to be outstanding at one time more than one Advance Facility with respect to
Advances or more than one Advance Facility with respect to Servicing Advances.
Notwithstanding the existence of any Advance Facility under which an Advancing
Person agrees to fund Advances and/or Servicing Advances on such Servicer's
behalf, Wilshire or IndyMac, as applicable, shall remain obligated pursuant to
this Agreement to make Advances and Servicing Advances pursuant to and as
required by this Agreement, and shall not be relieved of such obligations by
virtue of such Advance Facility. If Wilshire or IndyMac enters into an Advance
Facility, and for so long as an Advancing Person remains entitled to receive
reimbursement for any Advances or Servicing Advances outstanding and previously
unreimbursed pursuant to this Agreement, then Wilshire or IndyMac, as
applicable, may elect by providing written notice to the Trustee not to be
permitted to reimburse itself for Advances and/or Servicing Advances, as
applicable, pursuant to Section 3.08 of this Agreement, but following any such
election Wilshire or IndyMac, as applicable, shall be required to include
amounts collected that would otherwise be retained by Wilshire or IndyMac, as
applicable, to reimburse it for previously unreimbursed Advances ("Advance
Reimbursement Amounts") and/or previously unreimbursed Servicing Advances
("Servicing Advance Reimbursement Amounts" and together with Advance
Reimbursement Amounts, "Reimbursement Amounts") (in each case to the extent such
type of Reimbursement Amount is included in the Advance Facility) in the
remittance to the Trustee made pursuant to this Agreement to the extent of
amounts on deposit in the Collection Account on the related Servicer Cash
Remittance Date. Notwithstanding anything to the contrary herein, in no event
shall Advance Reimbursement Amounts or Servicing Advance Reimbursement Amounts
be included in Interest Remittance Amounts or Principal Remittance Amounts or
distributed to Certificateholders. Wilshire or IndyMac, as applicable, if making
the election set forth herein, shall report to the Trustee the portions of the
Reimbursement Amounts that consist of Advance Reimbursement Amounts and
Servicing Advance Reimbursement Amounts, respectively.



                                       91
<PAGE>


                  (b)      If Wilshire or IndyMac enters into an Advance
Facility and makes the election set forth in Section 3.21(a), Wilshire or
IndyMac, as applicable, and the related Advancing Person shall deliver to the
Trustee a written notice and payment instruction (an "Advance Facility Notice"),
providing the Trustee with written payment instructions as to where to remit
Advance Reimbursement Amounts and/or Servicing Advance Reimbursement Amounts
(each to the extent such type of Reimbursement Amount is included within the
Advance Facility) on subsequent Distribution Dates. The payment instruction
shall require the applicable Reimbursement Amounts to be distributed to the
Advancing Person or to a trustee or custodian (an "Advance Facility Trustee")
designated in the Advance Facility Notice. An Advance Facility Notice may only
be terminated by the joint written direction of Wilshire or IndyMac, as
applicable, and the related Advancing Person (and any related Advance Facility
Trustee); PROVIDED, HOWEVER, that the provisions of this Section 3.21 shall
cease to be applicable when all Advances and Servicing Advances funded by an
Advancing Person, and when all Advances and Servicing Advances (the rights to be
reimbursed for which have been assigned or pledged to an Advancing Person), have
been repaid to the related Advancing Person in full.

                  (c)      Reimbursement Amounts shall consist solely of amounts
in respect of Advances and/or Servicing Advances made with respect to the
Mortgage Loans for which Wilshire or IndyMac, as applicable, would be permitted
to reimburse itself in accordance with Section 3.08(ii), (iii) and (iv) hereof,
assuming Wilshire or IndyMac, as applicable, had made the related Advance(s)
and/or Servicing Advance(s). Notwithstanding the foregoing, no Person shall be
entitled to reimbursement from funds held in the Collection Account for future
distribution to Certificateholders pursuant to the provisions of Section 4.01.
The Trustee shall not have any duty or liability with respect to the calculation
of any Reimbursement Amount and shall be entitled to rely without independent
investigation on the Advance Facility Notice and on the applicable Servicer's
report of the amount of Advance Reimbursement Amounts and Servicing Advance
Reimbursement Amounts that were included in the remittance from Wilshire or
IndyMac, as applicable, to the Trustee pursuant to Section 3.08(viii). Wilshire
or IndyMac, as applicable, 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 Advancing Person. The successor Servicer
shall be entitled to rely on any such information provided by Wilshire or
IndyMac, as applicable, and the successor Servicer shall not be liable for any
errors in such information.

                  (d)      An Advancing Person who receives an assignment or
pledge of the rights to be reimbursed for Advances and/or Servicing Advances,
and/or whose obligations hereunder are limited to the funding of Advances and/or
Servicing Advances shall not be required to meet the criteria for qualification
of a Subservicer set forth in Section 3.02 hereof.

                  (e)      With respect to any Advance Facility pursuant to
which Wilshire or IndyMac has made the election set forth in Section 3.21(a),
the documentation establishing any Advance Facility shall require that
Reimbursement Amounts distributed with respect to each Mortgage Loan be
allocated to outstanding unreimbursed Advances or Servicing Advances (as the
case may be) made with respect to that Mortgage Loan on a "first-in, first-out"
(FIFO) basis. Such documentation shall also require Wilshire or IndyMac, as
applicable, to provide to the



                                       92
<PAGE>


related Advancing Person or Advance Facility Trustee loan-by-loan information
with respect to each Reimbursement Amount distributed by the Trustee to such
Advancing Person or Advance Facility Trustee on each Distribution Date, to
enable the Advancing Person or Advance Facility Trustee to make the FIFO
allocation of each Reimbursement Amount with respect to each Mortgage Loan.
Wilshire or IndyMac, as applicable, shall remain entitled to be reimbursed by
the Advancing Person or Advance Facility Trustee for all Advances and Servicing
Advances funded by Wilshire or IndyMac, as applicable, to the extent the related
rights to be reimbursed therefor have not been assigned or pledged to an
Advancing Person.

                  (f)      If Wilshire or IndyMac enters into an Advance
Facility, Wilshire or IndyMac, as applicable, shall indemnify the Trustee and
the Trust 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 successor Servicer or the Trustee, or failure by
the successor Servicer or the Trustee to remit funds as required by Section
3.21(b). Any amendment to this Section 3.21 or to any other provision of this
Agreement that may be necessary or appropriate to effect the terms of an Advance
Facility as described generally in this Section 3.21, including amendments to
add provisions relating to a successor Servicer, may be entered into by the
Trustee, the Seller and Wilshire or IndyMac, as applicable, without the consent
of any Certificateholder notwithstanding anything to the contrary in Section
10.01 of or elsewhere in this Agreement.

                                DISTRIBUTIONS AND
                            ADVANCES BY THE SERVICER

                  SECTION 4.01 Advances by the Servicer.

                  Each Servicer shall deposit in a Collection Account an amount
equal to (i) with respect to the Mortgage Loans other than the Simple Interest
Mortgage Loans, all Scheduled Payments (with interest at the Mortgage Rate less
the Servicing Fee Rate) which were due but not received on the related Mortgage
Loans during the applicable Due Period and (ii) with respect to the Simple
Interest Mortgage Loans, 30 day's interest on each such Mortgage Loan for which
the Scheduled Payment was due but not received during the applicable Due Period,
less the Servicing Fee; provided however, that with respect to any Balloon Loan
that is delinquent on its maturity date, the related Servicer will not be
required to advance the related balloon payment but will be required to continue
to make Advances in accordance with this Section 4.01 with respect to such
Balloon Loan in an amount equal to an assumed scheduled payment that would
otherwise be due based on the original amortization schedule for that Mortgage
Loan (with interest at the Mortgage Rate less the Servicing Fee Rate). Each
Servicer's obligation to make such Advances as to any related Mortgage Loan will
continue through the last Scheduled Payment due prior to the payment in full of
such Mortgage Loan, or through the date that the related Mortgaged Property has,
in the judgment of such Servicer, been completely liquidated; provided however,
that such obligation with respect to any related Mortgage Loan shall cease if
such Servicer determines, in its reasonable opinion, that Advances with respect
to such Mortgage Loan are Nonrecoverable Advances; provided that the related
Servicer will be required to make Advances until the earlier of (i) the time at
which the related Mortgage Loan becomes 120 days delinquent or (ii) the time at
which the Servicer determines that such Advances with respect to such Mortgage
Loan are Nonrecoverable Advances. In the event that such Servicer determines
that any such Advances are Nonrecoverable Advances, such Servicer shall provide
the Trustee with a certificate signed by a Servicing Officer evidencing such
determination.

                  If an Advance is required to be made hereunder, the related
Servicer shall on the second Business Day immediately preceding the Distribution
Date immediately following the related Determination Date either (i) deposit in
the Collection Account from its own funds an amount equal to such Advance, (ii)
cause to be made an appropriate entry in the records of the Collection Account
that funds in such account being held for future distribution or withdrawal have
been, as permitted by this Section 4.01, used by the related Servicer to make
such Advance or (iii) make Advances in the form of any combination of clauses
(i) and (ii) aggregating the amount of such Advance. Any such funds being held
in a Collection Account for future distribution and so used shall be replaced by
the related Servicer from its own funds by deposit in such Collection Account on
or before any future Distribution Date in which such funds would be due. The
related Servicer shall be entitled to be reimbursed from the Collection Account
for all Advances of its own funds made pursuant to this Section as provided in
Section 3.08.

                  SECTION 4.02 Priorities of Distribution.

                  (a)      On each Distribution Date, prior to making
distributions to the holders of the Certificates, the Trustee first, shall pay
itself the Trustee's Fee for such Distribution Date and second, shall pay the
Credit Risk Manager the Credit Risk Manager Fee for such Distribution Date.

                  (b)      With respect to the Available Funds, on each
Distribution Date, the Trustee shall withdraw such Available Funds from the
Certificate Account and based on the information provided to it by the
Servicers, apply such funds to distributions on the Certificates in the
following order and priority and, in each case, to the extent of such Available
Funds remaining:

                  (i)      On each Distribution Date, the Trustee shall
         distribute the Interest Remittance Amount for such date in the
         following order of priority:

                  A.       to the Class X-S Certificates, the aggregate Excess
                           Servicing Fee for such Distribution Date;

                  B.       to the Class A-1, Class A-2, Class A-3, Class A-R,
                           Class A-RL and Class P Certificates, concurrently and
                           pro rata, Current Interest and any Carryforward
                           Interest, as applicable, for each such Class and such
                           Distribution Date;

                  C.       to the Class M-1 Certificates, Current Interest and
                           any Carryforward Interest for such Class and such

                  (v)      On each Distribution Date, the Trustee shall
         distribute to the Holder of the Class P Certificate, the aggregate of
         all Prepayment Charges collected during the preceding Prepayment
         Period.

                  (vi)     [reserved].

                  (vii)    On each Distribution Date, following the foregoing
         distributions, an amount equal to the amount of Net Recoveries included
         in the Available Funds for such Distribution Date shall be applied to
         increase the Class Principal Balance of the Class of Certificates with
         the Highest Priority up to the extent of such Realized Losses
         previously allocated to that Class of Certificates pursuant to Section
         4.05. An amount equal to the amount of any remaining Net Recoveries
         shall be applied to increase the Class Principal Balance of the Class
         of Certificates with the next Highest Priority, up to the amount of
         such Realized Losses previously allocated to that Class of Certificates
         pursuant to Section 4.05, and so on. Holders of such Certificates will
         not be entitled to any distribution in respect of interest on the
         amount of such increases for any Interest Accrual Period preceding the
         Distribution Date on which such increase occurs. Any such increases
         shall be applied to the Class Principal Balance of each Certificate of
         such Class in accordance with its respective Percentage Interest.

                  On each Distribution Date, the Trustee shall determine the
total of the Applied Loss Amount, if any, for such Distribution Date. The
Applied Loss Amount for any Distribution Date shall be applied by reducing the
Class Principal Balance of each Class of Subordinate Certificates beginning with
the Class of Subordinate Certificates then outstanding with the lowest relative
payment priority, in each case until the respective Class Principal Balance
thereof is reduced to zero. Any Applied Loss Amount allocated to a Class of
Subordinate Certificates shall be allocated among the Subordinate Certificates
of such Class in proportion to their respective Percentage Interests.

                  All Realized Losses on the Mortgage Loans shall be allocated
on each Distribution Date to the following REMIC 1 Regular Interests: first, to
REMIC 1 Regular Interests LTI-1 until the Uncertificated Principal Balance
thereof has been reduced to zero, then to REMIC 1 Regular Interest LTI-PF until
the Uncertificated Principal Balance thereof has been reduced to zero, however,
that with respect to the first three Distribution Dates, Realized Losses
relating to the Initial Mortgage Loans shall be allocated to REMIC 1 Regular
Interest LTI-1 and Realized Losses relating to the Subsequent Mortgage Loans
shall be allocated to REMIC 1 Regular Interest LTI-PF until the Uncertificated
Principal Balance thereof has been reduced to zero. All Realized Losses on the
REMIC 1 Regular Interests LTI-1 and LTI-PF shall be deemed to have been
allocated to the following REMIC 2 Regular Interests in the specified

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. For the avoidance of doubt, the related Servicer may waive a
Prepayment Charge in connection with a short sale or short payoff on a defaulted
Mortgage Loan. If the related Servicer has waived all or a portion of a
Prepayment Charge relating to a Principal Prepayment, other than as provided
above, the related Servicer shall deliver to the Trustee no later than the
Business Day immediately preceding the next Distribution Date, for deposit into
the Certificate Account the amount of such Prepayment Charge (or such portion
thereof as had been waived) for distribution in accordance with the terms of
this Agreement; provided, however, the related Servicer shall not have any
obligation to pay the amount of any uncollected Prepayment Charge under this
Section 4.09 if such Servicer did not have a copy of the related Mortgage Note,
such Servicer requested via email a copy of the same from the Trustee and the
Trustee failed to provide such a copy within two (2) Business Days of receipt of
such request. If the related Servicer has waived all or a portion of a
Prepayment Charge for any reason, it shall promptly notify the Trustee thereof
and shall include such information in any monthly reports it provides the
Trustee. Notwithstanding any provision in this Agreement to the contrary, in the
event the Prepayment Charge payable under the terms of the Mortgage Note is
different from the amount of the Prepayment Charge set forth in the Mortgage
Loan Schedule or other information provided to the related Servicer, such
Servicer shall rely conclusively on the Prepayment Charge as set forth under the
terms of the Mortgage Note. To the extent the Prepayment Charge payable under
the terms of the Mortgage Note is less than the amount of the Prepayment Charge
set forth in the Mortgage Loan Schedule or other information provided to the
related Servicer, such Servicer shall not have any liability or obligation with
respect to such difference, and in addition shall not have any liability or
obligation to pay the amount of any uncollected Prepayment Charge if the failure
to collect such amount is the direct result of inaccurate or incomplete
information on the Mortgage Loan Schedule.

                  SECTION 4.10 Servicers to Cooperate.

                  Each Servicer shall provide to the Trustee the information set
forth in Exhibit Z hereto in such form as the Trustee shall reasonably request
with respect to each Mortgage Loan no later than twelve noon on the Servicer
Data Remittance Date to enable the Trustee to calculate



                                      106

the amounts to be distributed to each Class of Certificates and otherwise
perform its distribution, accounting and reporting requirements hereunder.

                                THE CERTIFICATES

                  SECTION 5.01 The Certificates.

                  The Certificates shall be substantially in the forms attached
hereto as exhibits. The Certificates shall be issuable in registered form, in
the minimum denominations, integral multiples in excess thereof (except that one
Certificate in each Class may be issued in a different amount which must be in
excess of the applicable minimum denomination) and aggregate denominations per
Class set forth in the Preliminary Statement.

                  Subject to Section 9.02 respecting the final distribution on
the Certificates, on each Distribution Date the Trustee shall make distributions
to each Certificateholder of record on the preceding Record Date either (x) by
wire transfer in immediately available funds to the account of such holder at a
bank or other entity having appropriate facilities therefor, if (i) such Holder
has so notified the Trustee at least five Business Days prior to the related
Record Date and (ii) such Holder shall hold (A) a Notional Amount Certificate,
(B) 100% of the Class Principal Balance of any Class of Certificates or (C)
Certificates of any Class with aggregate principal Denominations of not less
than $1,000,000 or (y) by check mailed by first class mail to such
Certificateholder at the address of such holder appearing in the Certificate
Register.

                  The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer upon the written
order of the Depositor. Certificates bearing the manual or facsimile signatures
of individuals who were, at the time such signatures were affixed, authorized to
sign on behalf of the Trustee shall bind the Trustee, notwithstanding that such
individuals or any of them have ceased to be so authorized prior to the
countersignature and delivery of any 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 countersigned
by the Trustee by manual signature, and such countersignature upon any
Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly executed and delivered hereunder. All Certificates
shall be dated the date of their countersignature. On the Closing Date, the
Trustee shall countersign the Certificates to be issued at the written direction
of the Depositor, or any affiliate thereof.

                  The Depositor shall provide, or cause to be provided, to the
Trustee on a continuous basis, an adequate inventory of Certificates to
facilitate transfers.

                  The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restriction or transfer imposed
under Article V of this Agreement or under applicable law with respect to any
transfer of any Certificate, or any interest therein, other than to require
delivery of the certification(s) and/or opinions of counsel described in Article
V applicable with respect to changes in registration of record ownership of
Certificates in the Certificate Register. The Trustee shall have no liability
for transfers, including transfers made



                                      108
<PAGE>


through the book-entry facilities of the Depository or between or among
Depository Participants or beneficial owners of the Certificates made in
violation of applicable restrictions.

                  SECTION 5.02 Certificate Register; Registration of Transfer
                               and Exchange of Certificates.

                  (a)      The Trustee shall maintain, or cause to be maintained
in accordance with the provisions of Section 5.06, a Certificate Register for
the Trust Fund in which, subject to the provisions of subsections (b) and (c)
below and to such reasonable regulations as it may prescribe, the Trustee shall
provide for the registration of Certificates and of transfers and exchanges of
Certificates as herein provided. Upon surrender for registration of transfer of
any Certificate, the Trustee shall execute and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and aggregate Percentage Interest.

                  At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
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 be accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
holder thereof or his attorney duly authorized in writing.

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

                  All Certificates surrendered for registration of transfer or
exchange shall be canceled and subsequently disposed of by the Trustee in
accordance with the Trustee's customary procedures.

                  (b)      No transfer of a Private Certificate shall be made
unless such transfer is made pursuant to an effective registration statement
under the Securities Act and any applicable state securities laws or is exempt
from the registration requirements under said Act and such state securities
laws. Except in connection with any transfer of a Private Certificate by the
Depositor to any affiliate, in the event that a transfer is to be made in
reliance upon an exemption from the Securities Act and such laws, in order to
assure compliance with the Securities Act and such laws, the Certificateholder
desiring to effect such transfer and such Certificateholder's prospective
transferee shall each certify to the Trustee and the Depositor in writing the
facts surrounding the transfer in substantially the form set forth in Exhibit J
(the "Transferor Certificate") and (i) deliver a letter in substantially the
form of either (A) Exhibit K (the "Investment Letter") provided that all of the
Class X Certificates of a Class shall be transferred to one investor or the
Depositor otherwise consents to such transfer, or (B) Exhibit L (the "Rule



                                      109
<PAGE>


144A Letter") or (ii) there shall be delivered to the Trustee and the Depositor
at the expense of the transferor an Opinion of Counsel that such transfer may be
made pursuant to an exemption from the Securities Act. The Depositor shall
provide to any Holder of a Private Certificate and any prospective transferee
designated by any such Holder, information regarding the related Certificates
and the Mortgage Loans and such other information as shall be necessary to
satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer
of any such Certificate without registration thereof under the Securities Act
pursuant to the registration exemption provided by Rule 144A. The Trustee and
the Servicers shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information regarding the Certificates, the Mortgage Loans and
other matters regarding the Trust Fund as the Depositor shall reasonably request
to meet its obligation under the preceding sentence. Each Holder of a Private
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify the Trustee, the Depositor, the Seller and the Servicers 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 an ERISA-Restricted Certificate shall be made
unless the Trustee and the Depositor shall have received either (i) a
representation from the transferee of such Certificate, acceptable to and in
form and substance satisfactory to the Trustee (in the event such Certificate is
a Private Certificate or a Residual Certificate, such requirement is satisfied
only by the Trustee's receipt of a representation letter from the transferee
substantially in the form of Exhibit K or Exhibit L, or Exhibit I, as
applicable), to the effect that such transferee is not an employee benefit plan
or arrangement subject to Section 406 of ERISA or a plan subject to Section 4975
of the Code (a "Plan"), nor a person acting on behalf of a Plan nor using the
assets of a Plan to effect such transfer or (ii) in the case of any such
ERISA-Restricted Certificate presented for registration in the name of an
employee benefit plan subject to ERISA, or a plan or arrangement subject to
Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or any other person acting on behalf
of any such plan or arrangement or using such plan's or arrangement's assets, an
Opinion of Counsel satisfactory to the Trustee, which Opinion of Counsel shall
not be an expense of either the Trustee or the Trust Fund, addressed to the
Trustee and the Depositor for the benefit of the Trustee, the Depositor and the
Servicers and on which they may rely, to the effect that the purchase or holding
of such ERISA-Restricted Certificate will not result in the assets of the Trust
Fund being deemed to be "plan assets" and subject to the prohibited transaction
provisions of ERISA and the Code and will not subject the Trustee, the Depositor
or the Servicers to any obligation in addition to those expressly undertaken in
this Agreement or to any liability. Notwithstanding anything else to the
contrary herein, any purported transfer of an ERISA-Restricted Certificate to or
on behalf of an employee benefit plan subject to ERISA or to the Code without
the delivery to the Trustee and the Depositor of an Opinion of Counsel
satisfactory to the Trustee as described above shall be void and of no effect.

                  No transfer of a Class B Certificate shall be made unless the
Trustee and the Depositor shall have received a representation from the
transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Trustee (such requirement is satisfied only by the Trustee's
and the Depositor's receipt of a representation letter from the transferee
substantially in



                                      110
<PAGE>


the form of Exhibit K or Exhibit L, as applicable), to the effect that either
(1) such transferee is not a Plan, nor a person acting on behalf of a Plan nor
using the assets of a Plan to effect such transfer, (2)(i) the transferee is an
insurance company and the source of funds used to purchase such Class B
Certificates is an "insurance company general account" (as such term is defined
in Prohibited Transaction Class Exemption 95-60), (ii) the conditions set forth
in Sections I and III of PTCE 95-60 have been satisfied and (iii) there is no
Plan with respect to which the amount of such general account's reserves and
liabilities for contracts held by or on behalf of such Plan and all other Plans
maintained by the same employer (or any affiliate thereof, as defined in PTCE
95-60) or by the same employee organization exceed 10% of the total of all
reserves and liabilities of such general account (as determined under PTCE
95-60) as of the date of the acquisition of such Class B Certificates) or (iii)
the transferee is a Plan and has provided an Opinion of Counsel satisfactory to
the Trustee, which Opinion of Counsel shall not be an expense of either the
Trustee or the Trust Fund, addressed to the Trustee and the Depositor for the
benefit of the Trustee, the Depositor and the Servicers and on which they may
rely, to the effect that the purchase or holding of such Class B Certificates or
interest therein is permissible under applicable law, will not constitute or
result in any non-exempt prohibited transaction under ERISA or Section 4975 of
the Code and will not subject the Trustee, the Depositor or the Servicers to any
obligation in addition to those expressly undertaken in this Agreement or to any
liability.

                  To the extent permitted under applicable law (including, but
not limited to, ERISA), the Trustee shall be under no liability to any Person
for any registration of transfer of any ERISA-Restricted Certificate that is in
fact not permitted by this Section 5.02(b) or 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 Trustee in accordance with the foregoing requirements.

                  (c)      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 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 Trustee of any change or impending change in
         its status as a Permitted Transferee.

                  (ii)     No Ownership Interest in a Residual Certificate may
         be registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Residual Certificate
         unless, in addition to the certificates required to be delivered to the
         Trustee under subparagraph (b) above, the Trustee and the Depositor
         shall have been furnished with an affidavit (a "Transfer Affidavit") of
         the initial owner or the proposed transferee in the form attached
         hereto as Exhibit I.



                                      111
<PAGE>


                  (iii)    Each Person holding or acquiring any Ownership
         Interest in a Residual Certificate shall agree (A) to obtain a Transfer
         Affidavit from any other Person to whom such Person attempts to
         Transfer its Ownership Interest in a Residual Certificate, (B) to
         obtain a Transfer Affidavit from any Person for whom such Person is
         acting as nominee, trustee or agent in connection with any Transfer of
         a Residual Certificate and (C) not to Transfer its Ownership Interest
         in a Residual Certificate or to cause the Transfer of an Ownership
         Interest in a Residual Certificate to any other Person if it has actual
         knowledge that such Person is not a Permitted Transferee.

                  (iv)     Any attempted or purported Transfer of any Ownership
         Interest in a Residual Certificate in violation of the provisions of
         this Section 5.02(c) shall be absolutely null and void and shall vest
         no rights in the purported Transferee. If any purported transferee
         shall become a Holder of a Residual Certificate in violation of the
         provisions of this Section 5.02(c), then the last preceding Permitted
         Transferee shall be restored to all rights as Holder thereof
         retroactive to the date of registration of Transfer of such Residual
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Residual Certificate that is in fact
         not permitted by Section 5.02(b) and this Section 5.02(c) or 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 after receipt of
         the related Transfer Affidavit and Transferor Certificate. The Trustee
         shall be entitled but not obligated to recover from any Holder of a
         Residual Certificate that was in fact not a Permitted Transferee at the
         time it became a Holder or, at such subsequent time as it became other
         than a Permitted Transferee, all payments made on such Residual
         Certificate at and after either such time. Any such payments so
         recovered by the Trustee shall be paid and delivered by the Trustee to
         the last preceding Permitted Transferee of such Certificate.

                  (v)      The Depositor shall use its best efforts to make
         available, upon receipt of written request from the Trustee, all
         information necessary to compute any tax imposed under Section 860E(e)
         of the Code as a result of a Transfer of an Ownership Interest in a
         Residual Certificate to any Holder who is not a Permitted Transferee.

                  The restrictions on Transfers of a Residual Certificate set
forth in this Section 5.02(c) shall cease to apply (and the applicable portions
of the legend on a Residual Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee,
the Seller or the Servicers, to the effect that the elimination of such
restrictions will not cause the Trust Fund hereunder to fail to qualify as a
REMIC at any time that the Certificates are outstanding or result in the
imposition of any tax on the Trust Fund, a Certificateholder or another Person.
Each Person holding or acquiring any Ownership Interest in a Residual
Certificate hereby consents to any amendment of this Agreement which, based on
an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Residual
Certificate is not transferred, directly or indirectly, to a Person that is not
a Permitted Transferee and (b) to provide for a means to compel the Transfer



                                      112
<PAGE>


of a Residual Certificate which is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

                  (d)      The preparation and delivery of all certificates and
opinions referred to above in this Section 5.02 in connection with transfer
shall be at the expense of the parties to such transfers.

                  (e)      Except as provided 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 the 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 Book-Entry Certificates; (iii)
ownership and transfers of registration of the Book-Entry 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
deal with the Depository, Depository Participants and indirect participating
firms as representatives of the Certificate Owners of the Book-Entry
Certificates for purposes of exercising the rights of holders under this
Agreement, and requests and directions for and votes of such representatives
shall not be deemed to be inconsistent if they are made with respect to
different Certificate Owners; and (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.

                  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 Owner. Each
Depository Participant shall only transfer Book-Entry Certificates of
Certificate Owners it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures.

                  If (x) (i) the Depository or the Depositor advises the Trustee
in writing that the Depository is no longer willing or able to properly
discharge its responsibilities as Depository, and (ii) the Trustee or the
Depositor is unable to locate a qualified successor, (y) the Depositor, with the
consent of the Depository Participants, advises the Trustee in writing that it
elects to terminate the book-entry system through the Depository or (z) after
the occurrence of an Event of Default, Certificate Owners representing at least
51% of the Certificate Balance of the Book-Entry Certificates together advise
the Trustee and the Depository through the Depository Participants in writing
that the continuation of a book-entry system through the Depository is no longer
in the best interests of the Certificate Owners, the Trustee shall notify all
Certificate Owners, through the Depository, of the occurrence of any such event
and of the availability of definitive, fully-registered Certificates (the
"Definitive Certificates") to Certificate Owners requesting the same. Upon
surrender to the Trustee of the related Class of Certificates by the Depository,
accompanied by the instructions from the Depository for registration, the
Trustee shall issue the Definitive Certificates.



                                      113
<PAGE>


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

                  None of the Seller, the Servicers, the Depositor or the
Trustee shall be liable for any delay in delivery of any instruction required
under this section and each may conclusively rely on, and shall be protected in
relying on, such instructions. The Depositor shall provide the Trustee with an
adequate inventory of certificates to facilitate the issuance and transfer of
Definitive Certificates. Upon the issuance of Definitive Certificates all
references herein to obligations imposed upon or to be performed by the
Depository shall be deemed to be imposed upon and performed by the Trustee, to
the extent applicable with respect to such Definitive Certificates and the
Trustee shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder; provided that the Trustee shall not by virtue of
its assumption of such obligations become liable to any party for any act or
failure to act of the Depository.

                  SECTION 5.03 Mutilated, Destroyed, Lost or Stolen
                               Certificates.

                  If (a) any mutilated Certificate is surrendered to the
Trustee, or the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there is delivered to the
Trustee such security or indemnity as may be required by it to hold it harmless,
then, in the absence of notice to the Trustee that such Certificate has been
acquired by a bona fide purchaser, the Trustee shall execute, countersign and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like Class, tenor and Percentage
Interest. In connection with the issuance of any new Certificate under this
Section 5.03, the Trustee may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected
therewith. Any replacement Certificate issued pursuant to this Section 5.03
shall constitute complete and indefeasible evidence of ownership,



                                      114
<PAGE>


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 Servicers, the Trustee and any agent of the Servicers or
the Trustee may treat the Person in whose name any Certificate is registered as
the owner of such Certificate for the purpose of receiving distributions as
provided in this Agreement and for all other purposes whatsoever, and none of
the Servicers, the Trustee or any agent of the Servicers or the Trustee shall be
affected by any notice to the contrary.

                  SECTION 5.05 Access to List of Certificateholders' Names and
                               Addresses.

                  If three or more Certificateholders (a) request such
information in writing from the Trustee, (b) state that such Certificateholders
desire to communicate with other Certificateholders with respect to their rights
under this Agreement or under the Certificates, and (c) provide a copy of the
communication which such Certificateholders propose to transmit, or if the
Depositor or a Servicer shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the Depositor, the Servicers or such Certificateholders at
such recipients' expense the most recent list of the Certificateholders of such
Trust Fund held by the Trustee, if any. The Depositor and every
Certificateholder, by receiving and holding a Certificate, agree that the
Trustee shall not be held accountable by reason of the disclosure of any such
information as to the list of the Certificateholders hereunder, regardless of
the source from which such information was derived.

                  SECTION 5.06 Maintenance of Office or Agency.

                  The Trustee will maintain or cause to be maintained at its
expense an office or offices or agency or agencies in New York, New York where
Certificates may be surrendered for registration of transfer or exchange. The
Trustee initially designates its Corporate Trust Office for such purposes. The
Trustee will give prompt written notice to the Certificateholders of any change
in such location of any such office or agency.

                   THE DEPOSITOR, THE SELLER AND THE SERVICERS

                  SECTION 6.01 Respective Liabilities of the Depositor, the
                               Sellers and the Servicers.

                  The Depositor, the Seller and each Servicer shall each be
liable in accordance herewith only to the extent of the obligations specifically
and respectively imposed upon and undertaken by them herein.

                  SECTION 6.02 Merger or Consolidation of the Depositor, the
                               Seller or a Servicer.

                  The Depositor, the Seller and each Servicer will each keep in
full effect its existence, rights and franchises as a corporation under the laws
of the United States or under the laws of one of the states thereof or as a
federally chartered savings bank organized under the laws of the United States
and will each obtain and preserve its qualification to do business as a foreign
corporation in each jurisdiction in which such qualification is or shall be
necessary to protect the validity and enforceability of this Agreement, or any
of the Mortgage Loans and to perform its respective duties under this Agreement.
Notwithstanding the foregoing, the Seller or a Servicer may be merged or
consolidated into another Person in accordance with the following paragraph.

                  Any Person into which the Depositor, the Seller or a Servicer
may be merged or consolidated, or any Person resulting from any merger or
consolidation to which the Depositor, the Seller or a Servicer shall be a party,
or any person succeeding to the business of the Depositor, the Seller or a
Servicer, shall be the successor of the Depositor, the Seller or a Servicer, 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 or surviving
Person with respect to a merger or consolidation of a Servicer shall be an
institution which is a Fannie Mae or Freddie Mac approved company in good
standing. In addition to the foregoing, there must be delivered to the Trustee a
letter from each of the Rating Agencies, to the effect that such merger,
conversion or consolidation of a Servicer will not result in a disqualification,
withdrawal or downgrade of the then current rating of any of the Certificates.

                  SECTION 6.03 Limitation on Liability of the Depositor, the
                               Seller, the Servicers and Others.

                  None of the Depositor, the Seller, any Servicer nor any of the
directors, officers, employees or agents of the Depositor, the Seller or any
Servicer shall be under any liability to 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



                                      116
<PAGE>


provision shall not protect the Depositor, the Seller, any Servicer or any such
Person against any breach of representations or warranties made by it herein or
protect the Depositor, the Seller, any Servicer or any such Person from any
liability which would otherwise be imposed by reasons of willful misfeasance,
bad faith or negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder. The Depositor, the Seller, each
Servicer and any director, officer, employee or agent of the Depositor, the
Seller or the a 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 Depositor, the Seller, the Trustee, the related Servicer
and any director, officer, employee or agent of the Depositor, the Seller, the
Trustee, or the related Servicer shall be indemnified by the Trust Fund out of
the Collection Account and held harmless against any loss, liability or expense
incurred in connection with any legal action relating to this Agreement
(including the provisions set forth in the last sentence of Section 2.01(a)) or
the Certificates, other than any loss, liability or expense incurred by reason
of willful misfeasance, bad faith or negligence in the performance of its duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder; provided, however, with respect to the provisions set forth in the
last sentence of Section 2.01(a), such indemnification will be without regard to
loss, liability or expense incurred by reason of any willful misfeasance, bad
faith or negligence in performance of its duties hereunder. None of the
Depositor, the Seller or any Servicer shall be under any obligation to appear
in, prosecute or defend any legal action that is not incidental to its
respective duties hereunder and which in its opinion may involve it in any
expense or liability; provided, however, that any of the Depositor, the Seller
or any Servicer may in its discretion undertake any such action that it may deem
necessary or desirable in respect of this Agreement and the rights and duties of
the parties hereto and interests of the Trustee and the Certificateholders
hereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust Fund, and the Depositor, the Seller and each Servicer shall be entitled to
be reimbursed therefor out of the Collection Account. Each Servicer's right to
indemnity or reimbursement pursuant to this Section 6.03 shall survive the
resignation or termination of such Servicer as set forth herein.

                  SECTION 6.04 Limitation on Resignation of a Servicer.

                  (a)      Subject to Section 6.04(b) below, a Servicer shall
not resign from the obligations and duties hereby imposed on it except (a)(i)
upon appointment, pursuant to the provisions of Section 7.02, of a successor
servicer which (x) has a net worth of not less than $10,000,000 and (y) is a
Fannie Mae or Freddie Mac approved company in good standing and (ii) receipt by
the Trustee of a letter from each Rating Agency that such a resignation and
appointment will not result in a qualification, withdrawal or downgrading of the
then current rating of any of the Certificates, or (b) upon determination that
its duties hereunder are no longer permissible under applicable law. Any such
determination under clause (b) permitting the resignation of a Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No
such resignation shall become effective until the Trustee or a successor
servicer shall have assumed such Servicer's responsibilities, duties,
liabilities and obligations hereunder and the requirements of Section 7.02 have
been satisfied.

                  (b)      Notwithstanding the foregoing and except with respect
to any IndyMac Serviced Loan, at the Seller's request, so long as it is the
owner of the servicing rights, Wilshire shall resign upon the Seller's selection
and appointment of a successor servicer; provided that the Seller delivers to
the Trustee the letter required by Section 6.04(a)(ii) above.

                                     DEFAULT

                  SECTION 7.01 Events of Default.

                  "Event of Default", wherever used herein, means any one of the
following events:

                  (i)      any failure by a Servicer to make any deposit or
         payment required pursuant to this Agreement which continues unremedied
         for a period of one Business Day (or, in the case of any such failure
         to make any deposit or payment due to any outbreak or escalation of
         hostilities, declaration by the United States of a national emergency
         or war or other calamity or crisis or act of god, for a period of three
         Business Days) after the date upon which written notice of such
         failure, requiring the same to be remedied, shall have been given to
         such Servicer by the Trustee or the Depositor, or to such Servicer and
         the Trustee by the Holders of Certificates having not less than 25% of
         the Voting Rights evidenced by the Certificates; or

                  (ii)     any failure by a Servicer duly to observe or perform
         in any material respect any other of the covenants or agreements on the
         part of such Servicer set forth in this Agreement, which failure or
         breach (a) materially affects the rights of the Certificateholders and
         (b) continues unremedied for a period of 30 days after the date on
         which written notice of such failure or breach, requiring the same to
         be remedied, shall have been given to such Servicer by the Trustee or
         the Depositor, or to such Servicer and the Trustee by the Holders of
         Certificates having not less than 25% of the Voting Rights evidenced by
         the Certificates; or

                  (iii)    if a representation or warranty set forth in Section
         2.03(b) hereof shall prove to be materially incorrect as of the time
         made in any respect that materially and adversely affects interests of
         the Certificateholders, and the circumstances or condition in respect
         of which such representation or warranty was incorrect shall not have
         been eliminated or cured, within 30 days (or, if such breach is not
         capable of being cured within 30 days and provided that the related
         Servicer believes in good faith that such breach can be cured and is
         diligently pursuing the cure thereof, within 90 days) after the date on
         which written notice thereof shall have been given to the related
         Servicer by the Trustee for the benefit of the Certificateholders or by
         the Depositor; or

                  (iv)     failure by a Servicer to maintain, if required, its
         license to do business in any jurisdiction where the related Mortgaged
         Property is located, to the extent such failure materially and
         adversely affects the ability of such Servicer to perform its
         obligations under this Agreement; or



                                      119
<PAGE>


                  (v)      a decree or order of a court or agency or supervisory
         authority having jurisdiction for the appointment of a conservator or
         receiver or liquidator in any insolvency, readjustment of debt,
         including bankruptcy, marshaling of assets and liabilities or similar
         proceedings, or for the winding-up or liquidation of its affairs, shall
         have been entered against a Servicer and such decree or order shall
         have remained in force undischarged or unstayed for a period of 60
         consecutive days; or

                  (vi)     a Servicer shall consent to the appointment of a
         conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshaling of assets and liabilities or similar proceedings of
         or relating to such Servicer or of or relating to all or substantially
         all of its property; or

                  (vii)    any failure of a Servicer to make any Advance, to the
         extent required under Section 4.01 in the manner and at the time
         required to be made from its own funds pursuant to this Agreement and
         after receipt of notice from the Trustee, which failure continues
         unremedied after the close of business on the Business Day immediately
         preceding the related Distribution Date; or

                  (viii)   a Servicer shall admit in writing its inability to
         pay its debts generally as they become due, file a petition to take
         advantage of or commence a voluntary case under, any applicable
         insolvency, bankruptcy or reorganization statute, make an assignment
         for the benefit of its creditors, voluntarily suspend payment of its
         obligations or cease its normal business operations for three Business
         Days; or

                  (ix)     (a) either (I) the servicer rankings or ratings of a
         Servicer are downgraded two or more levels below the level in effect on
         the Closing Date by one or more of the Rating Agencies rating the
         Certificates or (II) the servicer rankings or ratings for a Servicer
         are downgraded to "below average" status by one or more of the Rating
         Agencies rating the Certificates or (b) one or more Classes of the
         Certificates are downgraded or placed on negative watch due in whole or
         in part to the performance or servicing of a Servicer.

                  Other than an Event of Default resulting from a failure of a
Servicer to make any Advance, if an Event of Default described in clauses (i)
through (viii) of this Section shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
may, or at the direction of the Holders of Certificates evidencing not less than
51% of the Voting Rights evidenced by the Certificates, the Trustee shall by
notice in writing to such Servicer (with a copy to each Rating Agency),
terminate all of the rights and obligations of such Servicer under this
Agreement and in and to the related Mortgage Loans and the proceeds thereof,
other than its rights as a Certificateholder hereunder (and the rights to
reimburse itself for Advances and Servicing Advances previously made pursuant to
this Agreement, the right to accrued and unpaid Servicing Fees and the rights
under Section 6.03 with respect to events occurring prior to such termination).
If an Event of Default results from the failure of a Servicer to make an
Advance, the Trustee shall prior to the Distribution Date occurring in the
succeeding calendar month, by notice in writing to such Servicer and the



                                      120
<PAGE>


Depositor (with a copy to each Rating Agency), terminate all of the rights and
obligations of such Servicer under this Agreement prior to the Distribution Date
occurring in the succeeding calendar month and in and to the related Mortgage
Loans and the proceeds thereof, other than its rights as a Certificateholder
hereunder and the rights to reimburse itself for Advances and Servicing Advances
previously made pursuant to this Agreement, the right to accrued and unpaid
Servicing Fees and the rights under Section 6.03 with respect to events
occurring prior to such termination. If an Event of Default described in clause
(ix) of this Section occurs, the Trustee shall, at the direction of the Seller,
by notice in writing to the related Servicer, terminate all of the rights and
obligations of such Servicer under this Agreement (other than its right to
reimburse itself for Advances and Servicing Advances previously made, as
provided in Section 3.08, the right to accrued and unpaid Servicing Fees and the
rights under Section 6.03 with respect to events occurring prior to such
termination) and shall appoint as successor Servicer the entity selected by the
Seller in accordance with Section 7.02; provided the Seller shall first furnish
to the Trustee a letter from each Rating Agency that the appointment of such
successor will not result in a downgrading of the rating of any of the
Certificates.

                  Upon receipt by a Servicer of such written notice of
termination, all authority and power of such Servicer under this Agreement,
whether with respect to the Mortgage Loans serviced by it or otherwise, shall
pass to and be vested in the Trustee or its nominee. Upon written request from
the Trustee, such Servicer shall prepare, execute and deliver to the successor
entity designated by the Trustee any and all documents and other instruments,
place in such successor's possession all related Mortgage Files, and do or cause
to be done all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, including but not limited to the
transfer and endorsement or assignment of the Mortgage Loans and related
documents, at such Servicer's sole expense. The related Servicer shall cooperate
with the Trustee and such successor in effecting the termination of such
Servicer's responsibilities and rights hereunder, including without limitation,
the transfer to such successor for administration by it of all cash amounts, net
of unreimbursed Advances and Servicing Advances and unpaid Servicing Fees which
shall at the time be credited by the related Servicer to the Collection Account
or Escrow Account or thereafter received with respect to the Mortgage Loans
serviced by it. The Trustee, as successor Servicer, shall thereupon make any
Advance. The Trustee is hereby authorized and empowered to execute and deliver,
on behalf of the related Servicer, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the related Mortgage Loans and related documents, or otherwise.

                  SECTION 7.02 Trustee to Act; Appointment of Successor.

                  On and after the time a Servicer receives a notice of
termination pursuant to Section 7.01 of this Agreement or the resignation of a
Servicer pursuant to Section 6.04, the Trustee shall, subject to and to the
extent provided herein, be the successor to the related Servicer, but only in
its capacity as servicer under this Agreement, and not in any other, and the
transactions set forth herein and shall be subject to all the responsibilities,
duties and liabilities relating thereto placed on the related Servicer by the
terms and provisions hereof and applicable



                                      121
<PAGE>


law including the obligation to make Advances pursuant to Section 4.01. As
compensation therefor, the Trustee shall be entitled to all funds relating to
the Mortgage Loans that the related Servicer would have been entitled to charge
to the Collection Account, provided that the terminated Servicer shall
nonetheless be entitled to payment or reimbursement as provided in Section 3.08
to the extent that such payment or reimbursement relates to the period prior to
termination of the related Servicer. Notwithstanding the foregoing, if the
Trustee has become the successor to a Servicer in accordance with Section 7.01,
the Trustee may, if it shall be unwilling to so act, or shall, if it is
prohibited by applicable law from making Advances pursuant to 4.01 hereof, or if
it is otherwise unable to so act, appoint, or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution the
appointment of which does not adversely affect the then current rating of the
Certificates by each Rating Agency, as the successor to a Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of a Servicer hereunder. Any successor to a Servicer shall be an institution
which is a Fannie Mae or Freddie Mac approved seller/servicer for first and
second loans in good standing, which has a net worth of at least $10,000,000,
which is willing to service the related Mortgage Loans and which executes and
delivers to the Depositor and the Trustee an agreement accepting such delegation
and assignment, containing an assumption by such Person of the rights, powers,
duties, responsibilities, obligations and liabilities of the related Servicer
(other than liabilities of the related Servicer under Section 6.03 hereof
incurred prior to termination of the related Servicer under Section 7.01
hereunder), with like effect as if originally named as a party to this
Agreement; provided that each Rating Agency acknowledges that its rating of the
Certificates in effect immediately prior to such assignment and delegation will
not be qualified, withdrawn or downgraded as a result of such assignment and
delegation. Pending appointment of a successor to a Servicer hereunder, the
Trustee, unless the Trustee is prohibited by law from so acting, shall, subject
to the limitations described herein, act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the Trustee may
make such arrangements for the compensation of such successor out of payments on
the related Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of the Servicing Fee. The
Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. Neither the
Trustee nor any other successor servicer shall be deemed to be in default by
reason of any failure to make, or any delay in making, any distribution
hereunder or any portion thereof or any failure to perform, or any delay in
performing, any duties or responsibilities hereunder, in either case caused by
the failure of the related Servicer to deliver or provide, or any delay in
delivering or providing, any cash, information, documents or records to it.

                  In connection with the termination or resignation of any
Servicer hereunder, either (i) the successor servicer, including the Trustee if
the Trustee is acting as successor Servicer, shall represent and warrant that it
is a member of MERS in good standing and shall agree to comply in all material
respects with the rules and procedures of MERS in connection with the servicing
of the Mortgage Loans that are registered with MERS, in which case the
predecessor Servicer shall cooperate with the successor Servicer in causing MERS
to revise its records to reflect the transfer of servicing to the successor
Servicer as necessary under MERS' rules and regulations, or (ii) the predecessor
Servicer shall cooperate with the successor Servicer in causing MERS to execute
and deliver an assignment of Mortgage in recordable form to transfer



                                      122
<PAGE>


the Mortgage from MERS to the Trustee and to execute and deliver such other
notices, documents and other instruments as may be necessary or desirable to
effect a transfer of such Mortgage Loan or servicing of such Mortgage Loan on
the MERS(R) System to the successor Servicer. The predecessor Servicer shall
file or cause to be filed any such assignment in the appropriate recording
office. The predecessor Servicer shall bear any and all fees of MERS, costs of
preparing any assignments of Mortgage, and fees and costs of filing any
assignments of Mortgage that may be required under this subsection.

                  Any successor to a Servicer shall give notice to the
Mortgagors of such change of servicer and shall, during the term of its service
as servicer, maintain in force the policy or policies that such Servicer is
required to maintain pursuant to this Agreement.

                  SECTION 7.03 Notification to Certificateholders.

                  (a)      Upon any termination of or appointment of a successor
to a Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders and to each Rating Agency.

                  (b)      Within 60 days after the occurrence of any Event of
Default, the Trustee shall transmit by mail to all Certificateholders notice of
each such Event of Default hereunder actually known to the Trustee, unless such
Event of Default shall have been cured or waived.

                             CONCERNING THE TRUSTEE

                  SECTION 8.01 Duties of the Trustee.

                  The Trustee, prior to the occurrence of an Event of Default
and after the curing of all Events of Default that may have occurred, shall
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred and remains
uncured, 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 that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they are in
the form required by this Agreement; provided, however, that the Trustee shall
not be responsible for the accuracy or content of any such resolution,
certificate, statement, opinion, report, document, order or other 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 willful misconduct; provided, however, that:

                  (i)      unless an Event of Default actually known to the
         Trustee shall have occurred and be continuing, 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 the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon any certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Agreement which it believed in good faith to be genuine and to
         have been duly executed by the proper authorities respecting any
         matters arising hereunder;

                  (ii)     the Trustee shall not be liable for an error of
         judgment made in good faith by a Responsible Officer or Responsible
         Officers of the Trustee, unless it shall be finally proven that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (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 Holders of Certificates evidencing not
         less than 25% of the Voting Rights of Certificates relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the



                                      124
<PAGE>


         Trustee, or exercising any trust or power conferred upon the Trustee
         under this Agreement.

                  SECTION 8.02 Certain Matters Affecting the Trustee.

                  Except as otherwise provided in Section 8.01:

                  (i)      the Trustee may request and conclusively rely upon
         and shall be protected in acting or refraining from acting upon any
         resolution, Officers' Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document believed by
         it to be genuine and to have been signed or presented by the proper
         party or parties and the Trustee shall have no responsibility to
         ascertain or confirm the genuineness of any signature of any such party
         or parties;

                  (ii)     the Trustee may consult with counsel, financial
         advisers or accountants and the advice of any such counsel, financial
         advisers or accountants and any 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 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;

                  (iv)     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 document, unless
         requested in writing so to do by Holders of Certificates evidencing not
         less than 25% of the Voting Rights allocated to each Class of
         Certificates;

                  (v)      the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents, affiliates, accountants or attorneys;

                  (vi)     the Trustee shall not be required to risk or expend
         its own funds or otherwise incur any financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers hereunder if it shall have reasonable grounds for
         believing that repayment of such funds or adequate indemnity against
         such risk or liability is not assured to it;

                  (vii)    the Trustee shall not be liable for any loss on any
         investment of funds pursuant to this Agreement (other than as issuer of
         the investment security);

                  (viii)   the Trustee shall not be deemed to have knowledge of
         an Event of Default until a Responsible Officer of the Trustee shall
         have received written notice thereof; and



                                      125
<PAGE>


                  (ix)     the Trustee shall be under no obligation to exercise
         any of the trusts, 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 any of the
         Certificateholders, pursuant to the provisions of this Agreement,
         unless such Certificateholders shall have offered to the Trustee
         reasonable security or indemnity satisfactory to the Trustee against
         the costs, expenses and liabilities which may be incurred therein or
         thereby.

                  SECTION 8.03 Trustee Not Liable for Certificates or Mortgage
                               Loans.

                  The recitals contained herein and in the Certificates shall be
taken as the statements of the Depositor or the Seller, as the case may be, and
the Trustee assumes no responsibility for their correctness. The Trustee makes
no representations as to the validity or sufficiency of this Agreement or of the
Certificates or of any Mortgage Loan or related document, or of MERS or the
MERS(R) System, other than with respect to the Trustee's execution and
countersignature of the Certificates. The Trustee shall not be accountable for
the use or application by the Depositor or any Servicer of any funds paid to the
Depositor or a Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Depositor or a Servicer.

                  SECTION 8.04 Trustee May Own Certificates.

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

                  SECTION 8.05 Trustee's Fees and Expenses.

                  The Trustee, as compensation for its activities hereunder,
shall be entitled to withdraw from the Certificate Account on each Distribution
Date prior to making distributions pursuant to Section 4.02 an amount equal to
the Trustee Fee for such Distribution Date. The Trustee and any director,
officer, employee or agent of the Trustee shall be indemnified by the Depositor
and the Servicers, to the extent such indemnity related to the failure of the
related Servicer to perform its servicing obligations in accordance with this
Agreement, and held harmless against any loss, liability or expense (including
reasonable attorney's fees and expenses) (i) incurred in connection with any
claim or legal action relating to (a) this Agreement (including the provisions
set forth in the last sentence of Section 2.01(a)), (b) the Custodial Agreement,
(c) the Certificates, or (d) the performance of any of the Trustee's duties
hereunder, other than any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or negligence in the performance of any of the
Trustee's duties hereunder or incurred by reason of any action of the Trustee
taken at the direction of the Certificateholders; provided, however, with
respect to the provisions set forth in the last sentence of Section 2.01(a),
such indemnification will be without regard to loss, liability or expense
incurred by reason of any willful misfeasance, bad faith or negligence in the
performance of any of the Trustee's duties hereunder and (ii) resulting from any
error in any tax or information return prepared by the related Servicer. Such



                                      126
<PAGE>


indemnity shall survive the termination of this Agreement or the resignation or
removal of the Trustee hereunder. Without limiting the foregoing, the Depositor
covenants and agrees, except as otherwise agreed upon in writing by the
Depositor and the Trustee, and except for any such expense, disbursement or
advance as may arise from the Trustee's negligence, bad faith or willful
misconduct, to pay or reimburse the Trustee, for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Agreement with respect to: (A) the reasonable
compensation and the expenses and disbursements of its counsel not associated
with the closing of the issuance of the Certificates, (B) the reasonable
compensation, expenses and disbursements of any accountant, engineer or
appraiser that is not regularly employed by the Trustee, to the extent that the
Trustee must engage such persons to perform acts or services hereunder and (C)
printing and engraving expenses in connection with preparing any Definitive
Certificates. Except as otherwise provided herein, the Trustee shall not be
entitled to payment or reimbursement for any routine ongoing expenses incurred
by the Trustee in the ordinary course of its duties as Trustee, Registrar or
agent for the Tax Matters Person hereunder or for any other expenses.

                  SECTION 8.06 Eligibility Requirements for the Trustee and
                               Custodian.

                  The Trustee hereunder shall at all times be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating which would not cause either of the Rating Agencies to reduce their
respective then current Ratings of the Certificates (or having provided such
security from time to time as is sufficient to avoid such reduction) as
evidenced in writing by each Rating Agency. If such corporation or association
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
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the 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. The entity serving as
Trustee may have normal banking and trust relationships with the Depositor and
its affiliates or a Servicer and its affiliates; provided, however, that such
entity cannot be an affiliate of the Seller, the Depositor or a Servicer other
than the Trustee in its role as successor to a Servicer.

                  SECTION 8.07 Resignation and Removal of the Trustee.

                  The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice of resignation to the Depositor,
the Seller, each Servicer and each Rating Agency not less than 60 days before
the date specified in such notice, when, subject to Section 8.08, such
resignation is to take effect, and acceptance by a successor trustee in
accordance with Section 8.08 meeting the qualifications set forth in Section
8.06. If no successor trustee meeting such qualifications shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation or removal (as provided below), the



                                      127
<PAGE>


resigning or removed 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 thereto by the Depositor, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged as 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, or a tax
is imposed with respect to the Trust Fund by any state in which the Trustee or
the Trust Fund is located and the imposition of such tax would be avoided by the
appointment of a different trustee, then the Depositor may remove the Trustee
and appoint a successor trustee by written instrument, in triplicate, one copy
of which shall be delivered to the Trustee, one copy to each Servicer and the
Seller and one copy to the successor trustee.

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights may at any time remove the Trustee and appoint a successor trustee
by written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which shall be
delivered by the successor Trustee to each Servicer and the Seller, one complete
set to the Trustee so removed and one complete set to the successor so
appointed. Notice of any removal of the Trustee shall be given to each Rating
Agency by the successor trustee. All costs and expenses incurred by the Trustee
in connection with the removal of the Trustee without cause shall be reimbursed
to the Trustee from amounts on deposit in the Collection Account.

                  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
become effective upon 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 and to its predecessor
trustee and each Servicer and the Seller 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 the
like effect as if originally named as trustee herein. The Depositor, each
Servicer and the predecessor trustee shall execute and deliver such instruments
and do such other things as may reasonably be required for more fully and
certainly vesting and confirming in the successor trustee 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 its appointment shall
not adversely affect the then current rating of the Certificates.



                                      128
<PAGE>


                  Upon acceptance of appointment by a successor trustee as
provided in this Section 8.08, the Depositor shall mail notice of the succession
of such trustee hereunder to all Holders of Certificates. If the Depositor fails
to mail such notice within 10 days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Depositor.

                  SECTION 8.09 Merger or Consolidation of the Trustee.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated or any corporation resulting from
any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to the business of the Trustee, shall be the
successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 8.06 without the execution or filing of
any paper or further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

                  SECTION 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 Fund or property securing any Mortgage Note may at
the time be located, each Servicer 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 Fund, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust Fund or any part
thereof, whichever is applicable, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as each
Servicer and the Trustee may consider necessary or desirable. If a Servicer
shall not have joined in such appointment within 15 days after the receipt by it
of a request to do so, or in the case an Event of Default 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.

                  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)      To the extent necessary to effectuate the purposes of
         this Section 8.10, 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 a Servicer hereunder),
         the



                                      129
<PAGE>


         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 applicable Trust Fund 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
         such appointment shall not, and shall not be deemed to, constitute any
         such separate trustee or co-trustee as agent of the Trustee;

                  (iii)    The Trustee may at any time accept the resignation of
         or remove any separate trustee or co-trustee; and

                  (iv)     The Depositor, and not the Trustee, shall be liable
         for the payment of reasonable compensation, reimbursement and
         indemnification to any such 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 separate trustees and
co-trustees, when and 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 each Servicer and the Depositor.

                  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 Tax Matters.

                  It is intended that the assets with respect to which the REMIC
elections are to be made, as set forth in the Preliminary Statement, shall
constitute, and that the conduct of matters relating to each such segregated
pool of assets shall be such as to qualify such assets as, a "real estate
mortgage investment conduit" as defined in and in accordance with the Trust Fund
Provisions. In furtherance of such intention, the Trustee covenants and agrees
that it shall act as agent (and the Trustee is hereby appointed to act as agent)
for the Tax Matters Person and on behalf of the Trust Fund and that in such
capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a
timely manner, a U.S. Real Estate Mortgage Investment Conduit Income



                                      130
<PAGE>


Tax Return (Form 1066 or any successor form adopted by the Internal Revenue
Service) and prepare and file or cause to be prepared and filed with the
Internal Revenue Service and applicable state or local tax authorities income
tax or information returns for each taxable year with respect to each of REMIC
1, REMIC 2 and REMIC 3 containing such information and at the times and in the
manner as may be required by the Code or state or local tax laws, regulations,
or rules, and furnish or cause to be furnished to Certificateholders the
schedules, statements or information at such times and in such manner as may be
required thereby; (b) within thirty days of the Closing Date, furnish or cause
to be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise
may be required by the Code, the name, title, address, and telephone number of
the person that the holders of the Certificates may contact for tax information
relating thereto, together with such additional information as may be required
by such form, and update such information at the time or times in the manner
required by the Code; (c) make or cause to be made elections that the assets of
each of REMIC 1, REMIC 2 and REMIC 3 be treated as a REMIC on the federal tax
return for its first taxable year (and, if necessary, under applicable state
law); (d) prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary, state
tax authorities, all information returns and reports as and when required to be
provided to them in accordance with the REMIC Provisions, including without
limitation, the calculation of any original issue discount using the Prepayment
Assumption; (e) provide information necessary for the computation of tax imposed
on the transfer of a Residual Certificate to a Person that is not a Permitted
Transferee, or an agent (including a broker, nominee or other middleman) of a
Non-Permitted Transferee, or a pass-through entity in which a Non-Permitted
Transferee is the record holder of an interest (the reasonable cost of computing
and furnishing such information may be charged to the Person liable for such
tax); (f) to the extent that they are under its control, conduct matters
relating to such assets at all times that any Certificates are outstanding so as
to maintain the status of REMIC 1, REMIC 2 and REMIC 3 as a REMIC under the
REMIC Provisions; (g) not knowingly or intentionally take any action or omit to
take any action that would cause the termination of the REMIC status of REMIC 1,
REMIC 2 or REMIC 3; (h) pay, from the sources specified in the fourth paragraph
of this Section 8.11, the amount of any federal or state tax, including
prohibited transaction taxes as described below, imposed on the Trust Fund prior
to its termination when and as the same shall be due and payable (but such
obligation shall not prevent the Trustee or any other appropriate Person from
contesting any such tax in appropriate proceedings and shall not prevent the
Trustee from withholding payment of such tax, if permitted by law, pending the
outcome of such proceedings); (i) ensure that federal, state or local income tax
or information returns shall be signed by the Trustee or such other person as
may be required to sign such returns by the Code or state or local laws,
regulations or rules; (j) maintain records relating to the Trust Fund, including
but not limited to the income, expenses, assets and liabilities thereof and the
fair market value and adjusted basis of the assets determined at such intervals
as may be required by the Code, as may be necessary to prepare the foregoing
returns, schedules, statements or information; and (k) as and when necessary and
appropriate, represent the Trust Fund in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of the
Trust Fund, enter into settlement agreements with any governmental taxing
agency, extend any



                                      131
<PAGE>


statute of limitations relating to any tax item of the Trust Fund, and otherwise
act on behalf of the Trust Fund in relation to any tax matter or controversy
involving it.

                  To the extent that they are under its control, each Servicer
shall conduct matters relating to the assets of each REMIC at all times that any
Certificates are outstanding so as to maintain the status of REMIC 1, REMIC 2
and REMIC 3 as a REMIC under the REMIC Provisions. No Servicer shall knowingly
or intentionally take any action that would cause the termination of the REMIC
status of REMIC 1, REMIC 2 or REMIC 3.

                  In order to enable the Trustee to perform its duties as set
forth herein, the Depositor shall provide, or cause to be provided, to the
Trustee within ten (10) days after the Closing Date all information or data that
the Trustee requests in writing and determines to be relevant for tax purposes
to the valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor any such additional
information or data that the Trustee may, from time to time, reasonably request
in order to enable the Trustee to perform its duties as set forth herein. The
Depositor hereby indemnifies the Trustee for any losses, liabilities, damages,
claims or expenses of the Trustee arising from any errors or miscalculations of
the Trustee that result from any failure of the Depositor to provide, or to
cause to be provided, accurate information or data to the Trustee on a timely
basis.

                  In the event that any tax is imposed on "prohibited
transactions" of the Trust Fund as defined in Section 860F(a)(2) of the Code, on
the "net income from foreclosure property" of the Trust Fund as defined in
Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Trustee, if any such other tax arises out of or results from a breach by
the Trustee of any of its obligations under this Agreement, (ii) the related
Servicer or the Seller, in the case of any such minimum tax, if such tax arises
out of or results from a breach by such Servicer or the Seller of any of their
obligations under this Agreement or (iii) the Seller, if any such tax arises out
of or results from the Seller's obligation to repurchase a related Mortgage Loan
pursuant to Section 2.02 or 2.03 or (iv) in all other cases, or in the event
that the Trustee, the related Servicer or Seller fails to honor its obligations
under the preceding clauses (i), (ii) or (iii), any such tax will be paid with
amounts otherwise to be distributed to the Certificateholders, as provided in
Section 4.02.

                  Neither a Servicer nor the Trustee shall enter into any
arrangement by which any of REMIC 1, REMIC 2 or REMIC 3 will receive a fee or
other compensation for services nor permit any of REMIC 1, REMIC 2 or REMIC 3 to
receive any income from assets other than "qualified mortgages" as defined in
Section 860G(a)(3) of the Code or "permitted investments" as defined in Section
860G(a)(5) of the Code.

                  SECTION 8.12 Commission Reporting.

                  (a)      The Trustee and each Servicer shall reasonably
cooperate with the Depositor in connection with the Trust's satisfying the
reporting requirements under the Exchange Act. The Trustee shall prepare on
behalf of the Depositor any Forms 8-K and 10-K customary for similar securities
as required by the Exchange Act and the rules and regulations of the Commission
thereunder, and the Depositor shall sign and the Trustee shall file (via EDGAR)
such Forms on behalf of the Depositor. The Depositor hereby grants to the
Trustee a limited power of attorney to execute and file each such document on
behalf of the Depositor. Such power of attorney shall continue until the earlier
of (i) receipt by the Trustee from the Depositor of written termination of such
power of attorney and (ii) the termination of the Trust.

                  (b)      Each Form 8-K shall be filed by the Trustee within 15
days after each Distribution Date, with a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
March 31st of the calendar year following the calendar year during which the
Closing Date occurs (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, in substance as required by applicable law or applicable Commission
staff's interpretations. Such Form 10-K shall include as exhibits, each
Servicer's annual statement of compliance described under Section 3.16 and the
accountant's report described under Section 3.17, in each case to the extent
they have been timely delivered to the Trustee. If they are not so timely
delivered, the Trustee shall file an amended Form 10-K including such documents
as exhibits promptly after they are delivered to the Trustee. The Trustee shall
have no liability with respect to any failure to properly or timely 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 or
willful misconduct. The Form 10-K shall also include a certification in the form
attached hereto as Exhibit W (the "Depositor Certification"), which shall be
signed by the senior officer of the Depositor in charge of securitization. The
Trustee shall have no responsibility to file any items other than those
specified in this Section 8.12.

                  (c)      Not later than 15 calendar days before the date on
which the Depositor's annual report on Form 10-K is required to be filed in
accordance with the Exchange Act and the rules and regulations of the Commission
(or, if such day is not a Business Day, the immediately preceding Business Day),
the Trustee shall sign a certification in the form attached hereto as Exhibit X
(the "Trustee Certification") for the benefit of the Depositor and its officers,
directors and affiliates regarding certain aspects of items 1 through 3 of the
Depositor Certification. In addition, the Trustee shall, subject to the
provisions of Section 8.01 and 8.02 hereof, indemnify and hold harmless the
Depositor and each Person, if any, who "controls" the Depositor within the
meaning of the Securities Act and its officers, directors 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 a breach of the Trustee's obligations under this
Section 8.12 or any inaccuracy made in the Trustee Certification. If the
indemnification provided for in this Section 8.12(c) is unavailable or
insufficient to hold harmless such Persons, then the Trustee shall contribute to
the amount paid or payable by such Persons as a result of the losses, claims,
damages or liabilities of such Persons in such proportion



                                      133
<PAGE>


as is appropriate to reflect the relative fault of the Depositor on the one hand
and the Trustee on the other. The Trustee acknowledges that the Depositor is
relying on the Trustee's performance of its obligations under this Section 8.12
in order to perform its obligations under Section 8.12(b) above.

                  (d)      Not later than 15 calendar days before the date on
which the Depositor's annual report on Form 10-K is required to be filed in
accordance with the Exchange Act and the rules and regulations of the Commission
(or, if such day is not a Business Day, the immediately preceding Business Day),
each Servicer will deliver to the Depositor and the Trustee an Officer's
Certificate for the prior calendar year in substantially the form of Exhibit Y
to this Agreement. Each Servicer agrees to indemnify and hold harmless the
Depositor, the Trustee and each Person, if any, who "controls" the Depositor or
the Trustee within the meaning of the Securities Act and their respective
officers, directors and affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments and other costs, fees and expenses that such Person may sustain
arising out of third party claims based on (i) the failure of such Servicer to
deliver or caused to be delivered when required any Officer's Certificate
pursuant to this Section 8.12(d), or (ii) any material misstatement or omission
contained in any Officer's Certificate provided pursuant to this Section
8.12(d). If an event occurs that would otherwise result in an indemnification
obligation under clauses (i) or (ii) above, but the indemnification provided for
in this Section 8.12(d) by such Servicer is unavailable or insufficient to hold
harmless such Persons, then such Servicer shall contribute to the amount paid or
payable by such Persons as a result of the losses, claims, damages or
liabilities of such Persons in such proportion as is appropriate to reflect the
relative fault of the Depositor or Trustee on the one hand and such Servicer on
the other. Each Servicer acknowledges that the Depositor and the Trustee are
relying on such Servicer's performance of its obligations under this Agreement
in order to perform their respective obligations under this Section 8.12.

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

                  (f)      If the Commission issues additional interpretative
guidance or promulgates additional rules or regulations, or if other changes in
applicable law occur, that would require the reporting arrangements, or the
allocation of responsibilities with respect thereto, described in this Section
8.12, to be conducted differently than as described, the Depositor, Servicers
and Trustee will reasonably cooperate to amend the provisions of this Section
8.12 in order to comply with such amended reporting requirements and such
amendment of this Section 8.12. Any such amendment shall be made in accordance
with Section 10.01 without the consent of the Certificateholders, and may result
in a change in the reports filed by the Trustee on behalf of the Trust under the
Exchange Act. Notwithstanding the foregoing, the Depositor, Servicers and
Trustee shall not be obligated to enter into any amendment pursuant to this
Section 8.12 that adversely affects its obligations and immunities under this
Agreement.

                                   TERMINATION

                  SECTION 9.01 Termination upon Liquidation or Purchase of the
                               Mortgage Loans.

                  Subject to Section 9.03, the rights, obligations and
responsibilities of the Depositor, the Seller, the Servicers and the Trustee
created hereunder with respect to the Trust Fund shall terminate upon the
earliest of:

                  (a)      the purchase by the Optional Termination Holder of
all Mortgage Loans (and REO Properties) remaining at the price equal to the
greater of (I) the sum of (A) 100% of the Aggregate Collateral Balance (other
than in respect of REO Property) plus one month's accrued interest thereon at
the applicable Mortgage Rate, (B) with respect to any REO Property, the lesser
of (x) the appraised value of any REO Property as determined by the higher of
two independent valuations completed by two independent companies selected by
the Depositor at the expense of the Depositor and (y) the Stated Principal
Balance of each Mortgage Loan related to any REO Property, in each case plus
accrued and unpaid interest thereon at the applicable Mortgage Rate and (C) any
remaining unreimbursed Advances, Servicing Advances and Servicing Fees payable
to a Servicer and any unreimbursed Advances (made by the Trustee as a successor
Servicer), Trustee Fees and expenses payable to the Trustee (the sum of (A), (B)
and (C), collectively, the "Par Value") and (II) the Fair Market Value;

                  (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; and

                  (c)      the purchase by the Auction Purchaser of all the
Mortgage Loans and all property acquired in respect of any remaining Mortgage
Loan (the "Trust Collateral"), in each case as described below.

                  In no event shall the trusts created hereby continue beyond
the earlier of (i) the expiration of 21 years from the death of the survivor of
the descendants of Joseph P. Kennedy, the late Ambassador of the United States
to the Court of St. James's, living on the date hereof and (ii) the Latest
Possible Maturity Date. The right to repurchase all Mortgage Loans and REO
Properties pursuant to clause (a) above shall be conditioned upon the aggregate
Stated Principal Balance of the Mortgage Loans and the appraised value of the
REO Properties at the time of any such repurchase, aggregating less than ten
percent of the Aggregate Collateral Balance as of the Cut-off Date.



                                      136
<PAGE>


                  If the Optional Termination Holder has not exercised its
purchase option described above, on any Distribution Date on or after the date
on which the aggregate Stated Principal Balance of the Mortgage Loans and the
appraised value of the REO Properties at the time of the purchase is less than
five percent of the Aggregate Collateral Balance as of the Cut-off Date (the
"Auction Date"), the Trustee shall solicit, or cause to be solicited, good faith
bids for the Trust Collateral from at least three institutions that are regular
purchasers and/or sellers in the secondary market of residential whole mortgage
loans similar to the Mortgage Loans. If the Trustee receives at least three bids
for the Trust Collateral, and one of such bids is equal to or greater than the
Par Value, the Trustee shall sell the Trust Collateral to the highest bidder
(the "Auction Purchaser") at the price offered by the Auction Purchaser (the
"Mortgage Loan Purchase Price") and following such sale shall have no further
liability or responsibility therefor. If the Trustee receives less than three
bids, or does not receive any bid that is equal to or greater than the Par
Value, the Trustee shall continue conducting auctions every six months until the
earlier of (a) the completion of a successful auction and (b) the Optional
Termination Holder exercises its purchase option. Only expenses incurred by the
Trustee in connection with the solicitation of bids for a successful auction
described in this paragraph shall be payable to the Trustee, out of the Mortgage
Loan Purchase Price received in connection with such successful auction, as
described in Section 9.02 hereof; provided, however that any indemnification
rights available to the Trustee under this Agreement in connection with any
auctions will not be limited by this sentence.

                  SECTION 9.02 Final Distribution on the Certificates.

                  If on any Determination Date, the Trustee determines that
there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Collection Accounts and Certificate
Account, the Trustee shall promptly send a final distribution notice to each
Certificateholder. If the Optional Termination Holder above elects to terminate
the Trust Fund pursuant to Section 9.01 or the Auction Purchaser purchases the
Trust Collateral pursuant to Section 9.01, at least 20 days prior to the date
notice is to be mailed to the affected Certificateholders such Person shall
notify the Servicers and the Trustee of the date the Optional Termination Holder
or the Auction Purchaser intends to terminate the Trust Fund and of the
applicable repurchase price of the Mortgage Loans and REO Properties.

                  Notice of any termination of the Trust Fund, specifying the
Distribution Date on which Certificateholders shall surrender their Certificates
for payment of the final distribution and cancellation, shall be given promptly
by the Trustee by letter to Certificateholders mailed not earlier than the 10th
day and not later than the 15th day of the month next preceding the month of
such final distribution. Any such notice shall specify (a) the Distribution Date
upon which final distribution on the Certificates will be made upon presentation
and surrender of Certificates at the office therein designated, (b) the amount
of such final distribution, (c) the location of the office or agency at which
such presentation and surrender must be made, and (d) 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 therein specified. The Trustee shall give such notice to each Rating
Agency at the time such notice is given to Certificateholders.



                                      137
<PAGE>


                  Upon presentation and surrender of the Certificates, the
Trustee shall cause the final distribution to the Certificateholders of each
Class on the final Distribution Date to be made in accordance with the
priorities of Section 4.02. On the final Distribution Date, the
Overcollateralization Amount shall be distributed to the Class X-1 Certificates
in accordance with Section 4.02(b)(iv)(O) hereof. Notwithstanding the foregoing,
if the final Distribution Date has occurred as a result of the Optional
Termination Holder's purchase of the Trust Fund pursuant to Section 9.01(a) or
the purchase of the Trust Collateral by the Auction Purchaser pursuant to
Section 9.01(c), all amounts, if any, in excess of the Par Value shall be
distributed by the Trustee directly to the Class A-RL Certificateholders. All
amounts described in the definition of "Par Value" payable to the Trustee shall
be paid to the Trustee from the proceeds of an optional termination or from the
Mortgage Loan Purchase Price received in connection with a successful auction,
as applicable, prior to any distributions to Certificateholders.

                  In the event that any affected Certificateholders shall not
surrender Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Trustee shall give a second
written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. If within six months after the second notice all the applicable
Certificates shall not have been surrendered for cancellation, the Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining Certificateholders concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds and other
assets which remain a part of the Trust Fund. If within one year after the
second notice all Certificates shall not have been surrendered for cancellation,
the Class A-R Certificateholders and Class A-RL Certificateholders shall be
entitled to all unclaimed funds and other assets of the Trust Fund which remain
subject hereto and the Trustee shall be discharged from all further liability
with respect to the Certificates and this Agreement.

                  SECTION 9.03 Additional Termination Requirements.

                  (a)      In the event that the Optional Termination Holder
exercises its purchase option with respect to the Mortgage Loans as provided in
Section 9.01 or the Auction Purchaser purchases the Mortgage Loans pursuant to
Section 9.01, at such time as the Mortgage Loans are so purchased, the Trust
Fund shall be terminated in accordance with the following additional
requirements, unless the Trustee has been supplied with an Opinion of Counsel,
at the expense of the Depositor, to the effect that the failure to comply with
the requirements of this Section 9.03 will not (i) result in the imposition of
taxes on "prohibited transactions" on any REMIC as defined in Section 860F of
the Code, or (ii) cause REMIC 1, REMIC 2 and REMIC 3 to fail to qualify as a
REMIC at any time that any Certificates are outstanding:

                           (1)      Within 90 days prior to the final
                                    Distribution Date set forth in the notice
                                    given by the Trustee under Section 9.02, the
                                    Depositor shall prepare and the Trustee, at
                                    the expense of the Depositor, shall adopt a
                                    plan of complete liquidation within the
                                    meaning of Section 860F(a)(4) of the Code
                                    which, as evidenced by an Opinion of Counsel
                                    (which opinion shall not be an expense of
                                    the Trustee, the



                                      138

                                    Tax Matters Person or the Trust Fund), meets
                                    the requirements of a qualified liquidation;

                           (2)      Within 90 days after the time of adoption of
                                    such a plan of complete liquidation, the
                                    Trustee shall sell all of the assets of the
                                    Trust Fund to the Depositor for cash in
                                    accordance with Section 9.01; and

                                             On the date specified for final
                                    payment of the Certificates, the Trustee
                                    shall, after payment of any unreimbursed
                                    Advances, Servicing Advances, Servicing Fees
                                    or other fee compensation payable to each
                                    Servicer pursuant to this Agreement, make
                                    final distributions of principal and
                                    interest on the Certificates in accordance
                                    with Section 4.02 and distribute or credit,
                                    or cause to be distributed or credited, to
                                    the Holders of the Residual Certificates all
                                    cash on hand after such final payment (other
                                    than the cash retained to meet claims), and
                                    the Trust Fund (and any REMIC) shall
                                    terminate at that time.

                  (b)      The Trustee as agent for REMIC 1, REMIC 2 and REMIC 3
hereby agrees to adopt and sign such a plan of complete liquidation upon the
written request of the Depositor, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1) and to take such other action in connection
therewith as may be reasonably requested by the Depositor.

                  (c)      By their acceptance of the Certificates, the Holders
thereof hereby authorize the Depositor to prepare and the Trustee to adopt and
sign a plan of complete liquidation.

                            MISCELLANEOUS PROVISIONS

                  SECTION 10.01 Amendment.

                  This Agreement may be amended from time to time by the
Depositor, each Servicer, the Seller and the Trustee without the consent of any
of the Certificateholders (i) to cure any ambiguity or mistake, (ii) to correct
any defective provision herein or to supplement any provision herein which may
be inconsistent with any other provision herein, (iii) to add to the duties of
the Depositor, the Seller or any Servicer, (iv) to add any other provisions with
respect to matters or questions arising hereunder or (v) to modify, alter,
amend, add to or rescind any of the terms or provisions contained in this
Agreement; provided that any action pursuant to clauses (iv) or (v) above shall
not, as evidenced by an Opinion of Counsel (which Opinion of Counsel shall not
be an expense of the Trustee or the Trust Fund, but shall be at the expense of
the party proposing such amendment), adversely affect in any material respect
the interests of any Certificateholder; provided, however, that no such Opinion
of Counsel shall be required if the Person requesting the amendment obtains a
letter from each Rating Agency stating that the amendment would not result in
the downgrading or withdrawal of the respective ratings then assigned to the
Certificates; it being understood and agreed that any such letter in and of
itself will not represent a determination as to the materiality of any such
amendment and will represent a determination only as to the credit issues
affecting any such rating. The Trustee, the Depositor, the Seller and the
Servicers also may at any time and from time to time amend this Agreement
without the consent of the Certificateholders to modify, eliminate or add to any
of its provisions to such extent as shall be necessary or helpful to (i)
maintain the qualification of REMIC 1, REMIC 2 and REMIC 3 as a REMIC under the
Code, (ii) avoid or minimize the risk of the imposition of any tax on the Trust
Fund pursuant to the Code that would be a claim at any time prior to the final
redemption of the Certificates or (iii) comply with any other requirements of
the Code, provided that the Trustee has been provided an Opinion of Counsel,
which opinion shall be an expense of the party requesting such opinion but in
any case shall not be an expense of the Trustee or the Trust Fund, to the effect
that such action is necessary or helpful to, as applicable, (i) maintain such
qualification, (ii) avoid or minimize the risk of the imposition of such a tax
or (iii) comply with any such requirements of the Code.

                  This Agreement may also be amended from time to time by the
Depositor, the Servicers, the Seller and the Trustee with the consent of the
Holders of a Majority in Interest 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 this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments 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, as to such Class, Percentage Interests



                                      140
<PAGE>


aggregating 66%, or (iii) reduce the aforesaid percentages of Certificates the
Holders of which are required to consent to any such amendment, without the
consent of the Holders of all such Certificates then outstanding.

                  Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, which opinion shall not be an expense
of the Trustee or the Trust Fund, but shall be at the expense of the party
preparing such amendment, to the effect that such amendment will not cause the
imposition of any federal tax on the Trust Fund or the Certificateholders or
cause REMIC 1, REMIC 2 and REMIC 3 to fail to qualify as a REMIC at any time
that any Certificates are outstanding.

                  Promptly after the execution of any amendment to this
Agreement, the Trustee shall furnish written notification of the substance or a
copy of such amendment to each Certificateholder if the consent of
Certificateholders was required and each Rating Agency.

                  It shall not be necessary for the consent of
Certificateholders under this Section 10.01 to approve the particular form of
any proposed amendment, but 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.

                  Nothing in this Agreement shall require the Trustee to enter
into an amendment without receiving an Opinion of Counsel (which Opinion shall
not be an expense of the Trustee or the Trust Fund), satisfactory to the Trustee
that (i) such amendment is permitted and is not prohibited by this Agreement and
that all requirements for amending this Agreement have been complied with; and
(ii) either (A) the amendment does not adversely affect in any material respect
the interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 10.01.

                  SECTION 10.02 Recordation of Agreement; Counterparts.

                  This Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Depositor at its expense, but only upon
direction by the Trustee 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 an original, and such counterparts shall
constitute but one and the same instrument.

         been cured;

availing itself of any provisions of this Agreement to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this

nonassessable for any reason whatsoever, and that the Certificates, upon due
authentication thereof by the Trustee pursuant to this Agreement, are and shall
be deemed fully paid.

personally, by telephone, by mail, or electronically by e-mail or through the
internet or otherwise, solicit the borrower or obligor under any Mortgage Loan
to refinance the Mortgage Loan, in whole or in part. Notwithstanding the
foregoing, it is understood and agreed that promotions undertaken by the
Depositor, the Seller, any Servicer or the Trustee or any affiliate of any such
party that originates mortgage loans in the normal course, which are directed to
the general public at large, or segments thereof, including, without limitation,
mass mailings based on commercially acquired mailing lists or newspaper,
internet, company website, radio and television advertisements shall not
constitute solicitation under this Section 10.10, provided, that no segment of
the general public shall consist primarily of the borrowers or obligors under
the Mortgage Loans. None of the Depositor, the Seller, a Servicer or the Trustee
shall permit the sale of the name of any Mortgagor or any list of names that
consist primarily of the Mortgages to any Person.

          Home Equity Mortgage Pass-Through Certificates, Series 2005-2
                                 Class [_______]

         This Certificate is one of a duly authorized issue of Certificates
designated as Credit Suisse First Boston Mortgage Securities Corp., Mortgage
Pass-Through Certificates, of the Series specified on the face hereof (herein
collectively called the "Certificates"), and representing a beneficial ownership
interest in the Trust Fund created by the Agreement.

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

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

         Pursuant to the terms of the Agreement, a distribution will be made 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 on the
first Distribution Date specified on the face hereof, to the Person in whose
name this Certificate is registered at the close of business on the applicable
Record Date in an amount equal to the product of the Percentage Interest
evidenced by this Certificate and the amount required to be distributed to
Holders of Certificates of the Class to which this Certificate belongs on such
Distribution Date pursuant to the Agreement. [The Record Date applicable to each
Distribution Date is the last Business Day of the month next preceding the month
of such Distribution Date.][The Record Date applicable to each Distribution Date
is the Business Day immediately preceding the related Distribution Date;
provided that if this Certificate is not a Book-Entry Certificate, then the
Record Date applicable to each Distribution Date is the last Business Day of the
month next preceding such Distribution Date.]

         Distributions on this Certificate shall be made by wire transfer of
immediately available funds to the account of the Holder hereof at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing at least five Business Days prior
to the related Record Date and such Certificateholder shall satisfy the
conditions to receive such form of payment set forth in the Agreement, or, if
not, by check mailed by first class mail to the address of such
Certificateholder appearing in the Certificate Register. The final distribution
on each Certificate will be made in like manner, but only upon presentment and
surrender of such Certificate at the Corporate Trust Office or such other
location specified in the notice to Certificateholders of such final
distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Servicers, the Seller and the Trustee with the consent of
the Holders of Certificates affected by such amendment evidencing the requisite
Percentage Interest, as provided 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 therefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the Corporate Trust Office or the office or agency maintained by the
Trustee in New York, New York, accompanied by a 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 and evidencing the same aggregate Percentage Interest in the Trust
Fund will be issued to the designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations 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
and evidencing the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Depositor, the Servicers, the Seller and the Trustee and any agent
of the Depositor or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and the Seller,
the Depositor, the Trustee, or any such agent shall be affected by any notice to
the contrary.

         On any Distribution Date on which the sum of the aggregate Stated
Principal Balance of the Mortgage Loans and the appraised value of the REO
Properties at the time of repurchase is less than 10% of the sum of the
Aggregate Collateral Balance of the Mortgage Loans as of the Cut-off Date, the
Optional Termination Holder will have the option to repurchase, in whole, from
the Trust Fund all remaining Mortgage Loans and REO Properties at a purchase
price determined as provided in the Agreement. If the Optional Termination
Holder does not exercise its option to purchase, on any Distribution Date on
which the sum of the aggregate Stated Principal Balance of the Mortgage Loans
and the appraised value of the REO Properties at the time of repurchase is less
than 10% of the sum of the Aggregate Collateral Balance of the Mortgage Loans as
of the Cut-off Date, the Trustee shall conduct an auction and upon satisfaction
of the conditions described in the Agreement, the Auction Purchaser shall
purchase



                                      F-2
<PAGE>


the Trust Collateral at a purchase price determined as provided in the
Agreement. In the event that no such optional termination occurs and no purchase
pursuant to an auction occurs, the obligations and responsibilities created by
the Agreement will terminate upon the later of the maturity or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and the distribution to Certificateholders of all amounts required to
be distributed pursuant to the Agreement. In no event, however, will the trust
created by the Agreement continue beyond the expiration of 21 years from the
death of the last survivor of the descendants living at the date of the
Agreement of a certain person named in the Agreement.

         Any term used herein that is defined in the Agreement shall have the
meaning assigned in the Agreement, and nothing herein shall be deemed
inconsistent with that meaning.

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 [A-R][A-RL] Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Series, among Credit Suisse First
Boston Mortgage Securities Corp. as depositor, DLJ Mortgage Capital, Inc. as
seller ("DLJMC"), Wilshire Credit Corporation as a servicer ("Wilshire"),
IndyMac Bank, F.S.B. as a servicer and JPMorgan Chase Bank, N.A. as trustee (the
"Trustee"). Capitalized terms used, but not defined herein or in Exhibit 1
hereto, 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
its Ownership Interest in the Certificate either (i) for its own account or (ii)
as nominee, trustee or agent for another Person 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 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 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



                                      I-1
<PAGE>


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(c)
of the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the 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(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee 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 from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
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 its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as EXHIBIT J to the Agreement (a "Transferor Certificate") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

         7.       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 Certificate.

         8.       The Transferee's taxpayer identification number is
[_____________].

         9.       The Transferee is a United States Person.

         10.      The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of proposed 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.

         11.      The Transferee is (a) not an employee benefit plan that is
subject to ERISA or a plan that is subject to Section 4975 of the Code, and the
Transferee is not acting on behalf of such a plan or (b) an employee benefit
plan that is subject to ERISA or a plan that is subject to Section 4975 of the
Code, and the Transferee is not acting on behalf of such a plan and will provide
an Opinion of Counsel in accordance with the provisions of Agreement.

         "Ownership Interest": As to any Residual Certificate, any ownership or
security interest in such Certificate including any interest in such Certificate
as the Holder thereof and any other interest therein, whether direct or
indirect, legal or beneficial.

         "Permitted Transferee": Any person other than (i) the United States,
any State or political subdivision thereof, or any agency or instrumentality of
any of the foregoing, (ii) a foreign government, International Organization or
any agency or instrumentality of either of the foregoing, (iii) an organization
(except certain farmers' cooperatives described in section 521 of the Code)
which is exempt from tax imposed by Chapter 1 of the Code (including the tax
imposed by section 511 of the Code on unrelated business taxable income) on any
excess inclusions (as defined in section 860E(c)(1) of the Code) with respect to
any Residual Certificate, (iv) rural electric and telephone cooperatives
described in section 1381(a)(2)(C) of the Code, (v) a Person that is not a
United States Person, and (vi) a Person designated as a non-Permitted Transferee
by the Depositor based upon an Opinion of Counsel that the Transfer of an
Ownership Interest in a Residual Certificate to such Person may cause any REMIC
created hereunder to fail to qualify as a REMIC at any time that the
Certificates are outstanding. The terms "United States," "State" and
"International Organization" shall have the meanings set forth in section 7701
of the Code or successor provisions. A corporation will not be treated as an
instrumentality of the United States or of any State or political subdivision
thereof for these purposes if all of its activities are subject to tax and, with
the exception of Freddie Mac, a majority of its board of directors is not
selected by such government unit.

         "Person": Any individual, corporation, partnership, joint venture,
association, limited liability company, joint-stock company, trust,
unincorporated organization or government, or any agency or political
subdivision thereof.

         "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Residual Certificate.

                        SECTION 5.02(C) OF THE AGREEMENT
                        --------------------------------

         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
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 Trustee of any change or impending change in its status as a Permitted
Transferee.

         (ii)     No Ownership Interest in a Residual Certificate may be
registered on the Closing Date or thereafter transferred, and the Trustee shall
not register the Transfer of any Residual Certificate unless, in addition to the
certificates required to be delivered to the Trustee under subparagraph (b)
above, the Trustee shall have been furnished with an affidavit (a "Transfer
Affidavit") of the initial owner or the proposed transferee in the form attached
hereto as Exhibit I.

         (iii)    Each Person holding or acquiring any Ownership Interest in a
Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any
other Person to whom such Person attempts to Transfer its Ownership Interest in
a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for
whom such Person is acting as nominee, trustee or agent in connection with any
Transfer of a Residual Certificate and (C) not to Transfer its Ownership
Interest in a Residual Certificate or to cause the Transfer of an Ownership
Interest in a Residual Certificate to any other Person if it has actual
knowledge that such Person is not a Permitted Transferee.

         (iv)     Any attempted or purported Transfer of any Ownership Interest
in a Residual Certificate in violation of the provisions of this Section 5.02(c)
shall be absolutely null and void and shall vest no rights in the purported
Transferee. If any purported transferee shall become a Holder of a Residual
Certificate in violation of the provisions of this Section 5.02(c), then the
last preceding Permitted Transferee shall be restored to all rights as Holder
thereof retroactive to the date of registration of Transfer of such Residual
Certificate. The Trustee shall be under no liability to any Person for any
registration of Transfer of a Residual Certificate that is in fact not permitted
by Section 5.02(b) and this Section 5.02(c) or 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 after receipt of the related Transfer Affidavit and Transferor
Certificate. The Trustee shall be entitled but not obligated to recover from any
Holder of a Residual Certificate that was in fact not a Permitted Transferee at
the time it became a Holder or, at such subsequent time as it became other than
a Permitted Transferee, all payments made on such Residual Certificate at and
after either such time. Any such payments so recovered by the Trustee shall be
paid and delivered by the Trustee to the last preceding Permitted Transferee of
such Certificate.



                                     I-2-1
<PAGE>


         (v)      The Depositor shall use its best efforts to make available,
upon receipt of written request from the Trustee, all information necessary to
compute any tax imposed under Section 860E(e) of the Code as a result of a
Transfer of an Ownership Interest in a Residual Certificate to any Holder who is
not a Permitted Transferee.

                  The restrictions on Transfers of a Residual Certificate set
forth in this Section 5.02(c) shall cease to apply (and the applicable portions
of the legend on a Residual Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee,
the Seller or the Servicers, to the effect that the elimination of such
restrictions will not cause the Trust Fund hereunder to fail to qualify as a
REMIC at any time that the Certificates are outstanding or result in the
imposition of any tax on the Trust Fund, a Certificateholder or another Person.
Each Person holding or acquiring any Ownership Interest in a Residual
Certificate hereby consents to any amendment of this Agreement which, based on
an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Residual
Certificate is not transferred, directly or indirectly, to a Person that is not
a Permitted Transferee and (b) to provide for a means to compel the Transfer of
a Residual Certificate which is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

furnish to such parties updated annual financial statements promptly after they
become available.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
            --------------------------------------------------------

           [For Transferees That are Registered Investment Companies]

         The undersigned (the "Buyer") hereby certifies as follows to the
parties listed in the Rule 144A Transferee Certificate to which this
certification relates with respect to the Certificates described therein:

1.       As indicated below, the undersigned is the President, Chief Financial
         Officer or Senior Vice President of the Buyer or, if the Buyer is a
         "qualified institutional buyer" as that term is defined in Rule 144A
         under the Securities Act of 1933, as amended ("Rule 144A") because
         Buyer is part of a Family of Investment Companies (as defined below),
         is such an officer of the Adviser.

2.       In connection with purchases by Buyer, the Buyer is a "qualified
         institutional buyer" as defined in SEC Rule 144A because (i) the Buyer
         is an investment company registered under the Investment Company Act of
         1940, as amended and (ii) as marked below, the Buyer alone, or the
         Buyer's Family of Investment Companies, owned at least $100,000,000 in
         securities (other than the excluded securities referred to below) as of
         the end of the Buyer's most recent fiscal year. For purposes of
         determining the amount of securities owned by the Buyer or the Buyer's
         Family of Investment Companies, the cost of such securities was used,
         except (i) where the Buyer or the Buyer's Family of Investment
         Companies reports its securities holdings in its financial statements
         on the basis of their market value, and (ii) no current information
         with respect to the cost of those securities has been published. If
         clause (ii) in the preceding sentence applies, the securities may be
         valued at market.

         ___ The Buyer owned $[_____________] in securities (other than the
         excluded securities referred to below) as of the end of the Buyer's
         most recent fiscal year (such amount being calculated in accordance
         with Rule 144A).

         ___ The Buyer is part of a Family of Investment Companies which owned
         in the aggregate $[_____________] in securities (other than the
         excluded securities referred to below) as of the end of the Buyer's
         most recent fiscal year (such amount being calculated in accordance
         with Rule 144A).

3.       The term "Family of Investment Companies" as used herein means two or
         more registered investment companies (or series thereof) that have the
         same investment adviser or investment advisers that are affiliated (by
         virtue of being majority owned subsidiaries of the same parent or
         because one investment adviser is a majority owned subsidiary of the
         other).

4.       The term "securities" as used herein does not include (i) securities of
         issuers that are affiliated with the Buyer or are part of the Buyer's
         Family of Investment Companies, (ii) securities issued or guaranteed by
         the U.S. or any instrumentality thereof, (iii) bank deposit notes and
         certificates of deposit, (iv) loan participations, (v) repurchase



                                     L-2-1
<PAGE>


         agreements, (vi) securities owned but subject to a repurchase agreement
         and (vii) currency, interest rate and commodity swaps.

5.       The Buyer is familiar with Rule 144A and understands that the parties
         listed in the Rule 144A Transferee Certificate to which this
         certification relates are relying and will continue to rely on the
         statements made herein because one or more sales to the Buyer will be
         in reliance on Rule 144A. In addition, the Buyer will only purchase for
         the Buyer's own account.

6.       Until the date of purchase of the Certificates, the undersigned will
         notify the parties listed in the Rule 144A Transferee Certificate to
         which this certification relates of any changes in the information and
         conclusions herein. Until such notice is given, the Buyer's purchase of
         the Certificates will constitute a reaffirmation of this certification
         by the undersigned as of the date of such purchase.

                                   SCHEDULE IV

          REPRESENTATIONS AND WARRANTIES RELATING TO THE MORTGAGE LOANS

         DLJMC, in its capacity as Seller, hereby makes the representations and
warranties set forth in this Schedule IV to the Depositor and the Trustee, as of
the Closing Date, or the date specified herein, with respect to the Mortgage
Loans identified on Schedule I hereto.

         (i)      The Seller or its affiliate is the sole owner of record and
holder of the Mortgage Loan and the indebtedness evidenced by the Mortgage Note.
Immediately prior to the transfer and assignment to the Depositor on the Closing
Date, the Mortgage Loan, including the Mortgage Note and the Mortgage, were not
subject to an assignment or pledge, and the Seller had good and marketable title
to and was the sole owner thereof and had full right to transfer and sell the
Mortgage Loan to the Depositor free and clear of any encumbrance, equity, lien,
pledge, charge, claim or security interest and has the full right and authority
subject to no interest or participation of, or agreement with, any other party,
to sell and assign the Mortgage Loan and following the sale of the Mortgage
Loan, the Depositor will own such Mortgage Loan free and clear of any
encumbrance, equity, participation interest, lien, pledge, charge, claim or
security interest.

         (ii)     Any and all requirements of any federal, state or local law
including, without limitation, usury, truth-in-lending, real estate settlement
procedures, consumer credit protection, equal credit opportunity or disclosure
laws applicable to the Mortgage Loan have been complied with in all material
respects.

         (iii)    The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments which have been recorded to the extent any such recordation is
required by law, or, necessary to protect the interest of the Depositor. No
instrument of waiver, alteration or modification has been executed, and no
Mortgagor has been released, in whole or in part, from the terms thereof except
in connection with an assumption agreement and which assumption agreement is
part of the Mortgage File and the terms of which are reflected in the Mortgage
Loan Schedule; the substance of any such waiver, alteration or modification has
been approved by the issuer of any related Primary Insurance Policy and title
insurance policy, to the extent required by the related policies.

         (iv)     The Mortgage Loan complies with all the terms, conditions and
requirements of the originator's underwriting standards in effect at the time of
origination of such Mortgage Loan.

         (v)      The information set forth in the Mortgage Loan Schedule,
attached to the Agreement as Schedule I, is complete, true and correct in all
material respects as of the Cut-off Date.

         (vi)     With respect to any first lien Mortgage Loan, the related
Mortgage is a valid, subsisting, enforceable and perfected first lien on the
Mortgaged Property and, with respect to any second lien Mortgage Loan, the
related Mortgage is a valid, subsisting, enforceable and perfected second lien
on the Mortgaged Property, and all buildings on the Mortgaged Property and all
installations and mechanical, electrical, plumbing, heating and air conditioning
systems



                                      IV-1

affixed to such buildings, and all additions, alterations and replacements made
at any time with respect to the foregoing securing the Mortgage Note's original
principal balance. The Mortgage and the Mortgage Note do not contain any
evidence of any security interest or other interest or right thereto. Such lien
is free and clear of all adverse claims, liens and encumbrances having priority
over the first or second lien, as applicable, of the Mortgage subject only to
(1) with respect to any Second Mortgage Loan, the related First Mortgage Loan,
(2) the lien of non-delinquent current real property taxes and assessments not
yet due and payable, (3) covenants, conditions and restrictions, rights of way,
easements and other matters of the public record as of the date of recording
which are acceptable to mortgage lending institutions generally and either (A)
which are referred to or otherwise considered in the appraisal made for the
originator of the Mortgage Loan, or (B) which do not adversely affect the
appraised value of the Mortgaged Property as set forth in such appraisal, and
(4) other matters to which like properties are commonly subject which do not
materially interfere with the benefits of the security intended to be provided
by the Mortgage or the use, enjoyment, value or marketability of the related
Mortgaged Property. Any security agreement, chattel mortgage or equivalent
document related to and delivered in connection with the Mortgage Loan
establishes and creates (1) with respect to any First Mortgage Loan, a valid,
subsisting, enforceable and perfected first lien and first priority security
interest and (2) with respect to any second lien Mortgage Loan, a valid,
subsisting, enforceable and perfected second lien and second priority security
interest, in each case, on the property described therein, and the Seller has
the full right to sell and assign the same to the Depositor.

         (vii)    There are no mechanics' or similar liens or claims which have
been filed for work, labor or material (and no rights are outstanding that under
law could give rise to such liens) affecting the related Mortgaged Property
which are or may be liens prior to or equal to the lien of the related Mortgage.

         (viii)   All taxes, governmental assessments, insurance premiums,
water, sewer and municipal charges, leasehold payments or ground rents which
previously became due and owing have been paid, or escrow funds have been
established in an amount sufficient to pay for every such escrowed item which
remains unpaid and which has been assessed but is not yet due and payable.

         (ix)     The Mortgage Note and the Mortgage are not subject to any
right of rescission, set-off, counterclaim or defense, including, without
limitation, the defense of usury, nor will the operation of any of the terms of
the Mortgage Note or the Mortgage, or the exercise of any right thereunder,
render the Mortgage Note or Mortgage unenforceable, in whole or in part, or
subject to any right of rescission, set-off, counterclaim or defense, including
the defense of usury, and no such right of rescission, set-off, counterclaim or
defense has been asserted with respect thereto.

         (x)      The Mortgaged Property is not subject to any material damage
by waste, fire, earthquake, windstorm, flood or other casualty. At origination
of the Mortgage Loan there was, and there currently is, no proceeding pending
for the total or partial condemnation of the Mortgaged Property.

         (xi)     All improvements subject to the Mortgage which were considered
in determining the appraised value of the Mortgaged Property lie wholly within
the boundaries and building restriction lines of the Mortgaged Property (and
wholly within the project with respect to a condominium unit) and no
improvements on adjoining properties encroach upon the Mortgaged



                                      IV-2
<PAGE>


Property except those which are insured against by a title insurance policy and
all improvements on the property comply with all applicable zoning and
subdivision laws and ordinances.

         (xii)    Seller has delivered or caused to be delivered to the Trustee
or the Custodian on behalf of the Trustee the original Mortgage bearing evidence
that such instruments have been recorded in the appropriate jurisdiction where
the Mortgaged Property is located as determined by the Seller (or, in lieu of
the original of the Mortgage or the assignment thereof, a duplicate or conformed
copy of the Mortgage or the instrument of assignment, if any, together with a
certificate of receipt from the Seller or the settlement agent who handled the
closing of the Mortgage Loan, certifying that such copy or copies represent true
and correct copy(ies) of the original(s) and that such original(s) have been or
are currently submitted to be recorded in the appropriate governmental recording
office of the jurisdiction where the Mortgaged Property is located) or a
certification or receipt of the recording authority evidencing the same.

         (xiii)   The Mortgage File contains each of the documents specified in
Section 2.01(b) of the Agreement.

         (xiv)    As of the Closing Date, each Mortgage Loan shall be serviced
in all material respects in accordance with the terms of the Agreement.

         (xv)     All buildings or other customarily insured improvements upon
the Mortgaged Property are insured by an insurer acceptable under the FNMA
Guides, against loss by fire, hazards of extended coverage and such other
hazards as are provided for in the FNMA Guides or by FHLMC, as well as all
additional requirements set forth in this Agreement. All such standard hazard
policies are in full force and effect and on the date of origination contained a
standard mortgagee clause naming the Seller and its successors in interest and
assigns as loss payee and such clause is still in effect and all premiums due
thereon have been paid. If at the time of origination, the Mortgage Loan was
required to have flood insurance coverage in accordance with the Flood Disaster
Protection Act of 1973, as amended, such Mortgage Loan is covered by a flood
insurance policy meeting the requirements of the current guidelines of the
Federal Insurance Administration which policy conforms to FNMA and FHLMC
requirements, as well as all additional requirements set forth in this
Agreement. Such policy was issued by an insurer acceptable under FNMA or FHLMC
guidelines. The Mortgage obligates the Mortgagor thereunder to maintain all such
insurance at the Mortgagor's cost and expense, and upon the Mortgagor's failure
to do so, authorizes the holder of the Mortgage to maintain such insurance at
the Mortgagor's cost and expense and to seek reimbursement therefor from the
Mortgagor.

         (xvi)    With respect to each Mortgage Loan that has a Prepayment
Penalty feature, each such Prepayment Penalty is enforceable and, at the time
such Mortgage Loan was originated, each Prepayment Penalty complied with
applicable federal, state and local law, subject to federal preemption where
applicable.

         (xvii)   As of the Cut-off Date, no Mortgage Loan is (a) a
non-performing loan (i.e. a mortgage loan that is more than 90 days delinquent);
(b) a re-performing loan (i.e. a mortgage loan that was more than 90 days
delinquent within the twelve month period preceding the Cut-off Date but is
contractually current); or (c) a sub-performing loan (i.e. a mortgage loan that
is at least 30 days delinquent but subject to a payment plan or agreement
pursuant to which the Mortgagor is contractually current).



                                      IV-3

         (xviii)  The Mortgage Note and the related Mortgage are original and
genuine and each is the legal, valid and binding obligation of the maker
thereof, enforceable in all respects in accordance with its terms subject to
bankruptcy, insolvency, moratorium, reorganization and other laws of general
application affecting the rights of creditors and by general equitable
principles.

         (xix)    To the knowledge of the Seller, (i) no proceeds from any
Mortgage Loan were used to finance single-premium credit insurance policies,
(ii) no Mortgage Loan originated prior to October 1, 2002 will impose a
Prepayment Penalty for a term in excess of five years and no Mortgage Loan
originated on or after October 1, 2002 will impose a Prepayment Penalty for a
term in excess of three years, (iii) the related Servicer of each Mortgage Loan
has fully furnished, in accordance with the Fair Credit Reporting Act and its
implementing regulations, accurate and complete information on its borrower
credit files to Equifax, Experian and Trans Union Credit Information on a
monthly basis, (iv) the original principal balance of each Mortgage Loan is
within Freddie Mac's dollar amount for conforming one- to four-family mortgage
loans and (v) no Mortgage Loan secured by a Mortgaged Property located in the
State of Georgia was originated on or after October 1, 2002 and before March 7,
2003 and no Mortgage Loan secured by Mortgaged Property located in the State of
Georgia that was originated on or after March 7, 2003 is a "high cost home loan"
as defined in the Georgia Fair Lending Act (HB 1361), as amended.

         (xx)     Each Mortgage Loan at the time it was made complied in all
material respects with applicable local, state and federal laws, including, but
not limited to, all applicable predatory and abusive lending laws.

         (xxi)    No Mortgage Loan is classified as (a) a "high cost mortgage
loan" under the Home Ownership and Equity Protection Act of 1994 or (b) a "high
cost home," "covered," "high cost," "high risk home" or "predatory" loan under
any other applicable state, federal or local law (or a similarly classified loan
using different terminology under a law imposing heightened regulatory scrutiny
or additional legal liability for residential mortgage loans having high
interest rates, points and/or fees).

         (xxii)   No Mortgage Loan is a High Cost Loan or Covered Loan as such
terms are defined in Version 5.6 Revised; Appendix E of the Standard & Poor's
LEVELS(R) Glossary.

         (xxiii)  With respect to any Mortgage Loan originated on or after
October 1, 2004, either (a) the related Mortgage and the related Mortgage Note
does not contain a mandatory arbitration clause (that is, a clause that requires
the related Mortgagor to submit to arbitration to resolve any dispute arising
out of or relating in any way to the Mortgage Loan) or (b) the related Mortgage
and the related Mortgage Note contained a mandatory arbitration clause as of the
related origination date and such clause has or will be waived by the originator
or an entity designated by the Seller in writing no later than sixty (60) days
after the related Closing Date which notice included or will include the
following language: "WE ARE HEREBY NOTIFYING YOU THAT THE MANDATORY ARBITRATION
CLAUSE OF YOUR LOAN, REQUIRING THAT YOU SUBMIT TO ARBITRATION TO RESOLVE ANY
DISPUTE ARISING OUT OF OR RELATING IN ANY WAY TO YOUR MORTGAGE LOAN, IS
IMMEDIATELY NULL AND VOID. YOU ARE FREE TO CHOOSE TO EXERCISE ANY OF YOUR RIGHTS
OR ENFORCE ANY REMEDIES UNDER YOUR MORTGAGE LOAN THROUGH THE COURT

SYSTEM." A copy of the written notice referred to in the immediately preceding
sentence, if applicable, shall be retained in the related Mortgage File.
