         THIS POOLING AND SERVICING AGREEMENT, dated as of January 1, 2007,
among INDYMAC MBS, INC., a Delaware corporation, as depositor (the "Depositor"),
IndyMac Bank, F.S.B. ("IndyMac"), a federal savings bank, as seller (in that
capacity, the "Seller") and as servicer (in that capacity, the "Servicer"), and
Deutsche Bank National Trust Company, a national banking association, as trustee
(the "Trustee"),

                           W I T N E S S E T H T H A T

         In consideration of the mutual agreements set forth in this Agreement,
the parties agree as follows:

                     P R E L I M I N A R Y S T A T E M E N T

         The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. As provided in this Agreement, the
Trustee shall elect that the Trust Fund (exclusive of any amounts in respect of
waived Prepayment Charges paid by the Servicer to the Class P Certificates
pursuant to the second paragraph of Section 3.20) be treated for federal income
tax purposes as comprising two real estate mortgage investment conduits (each, a
"REMIC" or, in the alternative, "REMIC 1" and the "Master REMIC"). Each
Certificate, other than the Class A-R Certificate, will represent ownership of
one or more regular interests in the Master REMIC for purposes of the REMIC
Provisions. The Class A-R represents ownership of the sole class of residual
interest in each REMIC created under this Agreement. The Master REMIC will hold
as assets the several classes of uncertificated REMIC 1 Interests (other than
the Class R-1 Interest). REMIC 1 will hold as assets all property of the Trust
Fund. Each REMIC 1 Interest (other than the Class R-1 Interest) is hereby
designated as a regular interest in REMIC 1. The latest possible maturity date
of all REMIC regular interests created in this Agreement shall be the Latest
Possible Maturity Date. All amounts in respect of waived Prepayment Charges paid
by the Servicer to the Class P Certificates pursuant to the second paragraph of
Section 3.20 will be treated as paid directly by the Servicer to the Class P
Certificates and not as paid by or through any REMIC created under this
Agreement.

REMIC 1

         The REMIC 1 Regular Interests will have the initial principal balance,
Pass-Through Rates and corresponding Loan Groups as set forth in the following
table:

---------------
(1) Each Class A Interest will have a principal balance initially equal to 0.9%
of the Assumed Balance of its corresponding Loan Group. Each Class B Interest
will have a principal balance initially equal to 0.1% of the the Assumed Balance
of its corresponding Loan Group. The initial principal balance of each Class C
Interest will equal the excess of the initial aggregate principal balance of its
corresponding Loan Group over the initial aggregate principal balances of the
Class A and Class B Interests (and of the Class 1-$100 Interest, in the case of
the Class C-1 Interest) corresponding to such Loan Group.

(2) The Weighted Average Adjusted Net Mortgage Rate of the corresponding Loan
Group.

(3) The Class 1-P-1 and Class 1-P-2 Interests will not bear interest. The Class
1-P-1 Interests will be entitled to 100% of any Hard Prepayment Charges paid on
the Mortgage Loans. The Class 1-P-2 Interests will be entitled to 100% of any
Soft Prepayment Charges paid on the Mortgage Loans.

(4) The Weighted Average Adjusted Net Mortgage Rate of Loan Group 1.

(5) The Class R-1 Interest is the sole class of residual interest in REMIC 1. It
has no principal balance and pays no principal or interest.

         On each Distribution Date, the Available Funds shall be distributed
with respect to the REMIC 1 Interests in the following manner:

(1) Interest is to be distributed with respect to each REMIC 1 Interest
according to the formulas described above;

(2) Principal Amounts and Realized Losses will be allocated to make the Class
1-P and Class 1-$100 balance equal to the principal balances of the Class P and
Class A-R Certificates, respectively, for such Distribution Date.

(3) If Cross-Over Situation does not exist with respect to any Class of
Interests, then Principal Amounts and Realized Losses arising with respect to
each Loan Group will be allocated: first to cause the Loan Group's corresponding
Class A and Class B to equal, respectively, 0.9% of the Assumed Balance and 0.1%
of the Assumed Balance; and second to the Loan Group's corresponding Class C
Interest;

(4) If a Cross-Over Situation exists with respect to the Class A and Class B
Interests then:

         (a) if the Calculation Rate in respect of the outstanding Class A and
         Class B Interests is less than the Subordinate Pass-Through Rate,
         Principal Relocation Payments will be made proportionately to the
         outstanding Class A Interests prior to any other distributions of
         principal from each such Loan Group; and

         (b) if the Calculation Rate in respect of the outstanding Class A and
         Class B Interests is greater than the Subordinate Pass-Through Rate,
         Principal Relocation Payments will be made

                                       2
<PAGE>

         proportionately to the outstanding Class B Interests prior to any other
         distributions of principal from each such Loan Group.

In case of either (a) or (b), Principal Relocation Payments will be made so as
to cause the Calculation Rate in respect of the outstanding Class A and Class B
Interests to equal the Subordinate Pass-Through Rate. With respect to each Loan
Group, if (and to the extent that) the sum of (a) the principal payments
comprising the Principal Amount received during the Due Period and (b) the
Realized Losses on the Mortgage Loans in that Loan Group, are insufficient to
make the necessary reductions of principal on the Class A and Class B Interests,
then interest will be added to the Loan Group's other REMIC 1 Interests that are
not receiving Principal Relocation Payments, in proportion to their principal
balances.

         (c) Unless otherwise required to achieve the Calculation Rate, the
         outstanding aggregate Class A and Class B Interests for all Loan Groups
         will not be reduced below 1% of the excess of (i) the aggregate Stated
         Principal Balances of the Mortgage Loans as of the end of any Due
         Period (reduced by any Principal Prepayments received after the Due
         Period that are to be distributed on the Distribution Date related to
         the Due Period)over (ii) the Certificate Balance of the Senior
         Certificates (excluding the Class A-R Certificates) for all Certificate
         Groups as of the related Distribution Date (after taking into account
         distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (c) prevents the
distribution of principal to the Class A and Class B Interests of a Loan Group,
and if the Loan Group's Class C Interest has already been reduced to zero, then
the excess principal from that Loan Group will be paid to the Class C Interests
of the other Loan Group, the aggregate Class A and Class B Interests of which
are less than 1% of the Assumed Balance. If the Mortgage Loans in the Loan Group
of the Class C Interest that receives such payment has a Weighted Average
Adjusted Net Mortgage Rate below the Weighted Average Adjusted Net Mortgage Rate
of the Loan Group making the payment, then the payment will be treated by the
REMIC 1 as a Realized Loss. Conversely, if the Loan Group of the Class C
Interest that receives such payment has a Weighted Average Adjusted Net Mortgage
Rate above the Weighted Average Adjusted Net Mortgage Rate of the Loan Group
making the payment, then the payment will be treated by the REMIC 1 as a
reimbursement for prior Realized Losses.

                                The Master REMIC

         The following table sets forth characteristics of the Certificates,
together with the minimum denominations and integral multiples in excess thereof
in which such Classes shall be issuable (except that one Certificate of each
Class of Certificates may be issued in a different amount):

the Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC
regular interest, without creating any shortfall--actual or potential (other
than for credit losses) to any REMIC regular interest.

         For any purpose for which the Pass-Through Rates is calculated, the
interest rate on the Mortgage Loans shall be appropriately adjusted to account
for the difference between the monthly day count convention of the Mortgage
Loans and the monthly day count convention of the regular interests issued by
each of the REMICs. For purposes of calculating the Pass-Through Rates for each
of the interests issued by REMIC 1 and the Master REMIC such rates shall be
adjusted to equal a monthly day count convention based on a 30 day month for
each Due Period and a 360-day year so that the Mortgage Loans and all regular
interests will be using the same monthly day count convention.

         Except as otherwise expressly provided in this Agreement or unless the
context clearly requires otherwise

         (a) References to designated articles, sections, subsections, exhibits,
and other subdivisions of this Agreement, such as "Section 6.12 (a)," refer to
the designated article, section, subsection, exhibit, or other subdivision of
this Agreement as a whole and to all subdivisions of the designated article,
section, subsection, exhibit, or other subdivision. The words "herein,"
"hereof," "hereto," "hereunder," and other words of similar import refer to this
Agreement as a whole and not to any particular article, section, exhibit, or
other subdivision of this Agreement.

         (b) Any term that relates to a document or a statute, rule, or
regulation includes any amendments, modifications, supplements, or any other
changes that may have occurred since the document, statute, rule, or regulation
came into being, including changes that occur after the date of this Agreement.

         (c) Any party may execute any of the requirements under this Agreement
either directly or through others, and the right to cause something to be done
rather than doing it directly shall be implicit in every requirement under this
Agreement. Unless a provision is restricted as to time or limited as to
frequency, all provisions under this Agreement are implicitly available and
things may happen from time to time.

         (d) The term "including" and all its variations mean "including but not
limited to." Except when used in conjunction with the word "either," the word
"or" is always used inclusively (for example, the phrase "A or B" means "A or B
or both," not "either A or B but not both").

         (e) A reference to "a [thing]" or "any [of a thing]" does not imply the
existence or occurrence of the thing referred to even though not followed by "if
any," and "any [of a thing]" is any of it. A reference to the plural of anything
as to which there could be either one or more than one does not imply the
existence of more than one (for instance, the phrase "the obligors on a note"
means "the obligor or obligors on a note"). "Until [something occurs]" does not
imply that it must occur, and will not be modified by the word "unless." The
word "due" and the word "payable" are each used in the sense that the stated
time for payment has passed. The word "accrued" is used in its accounting sense,
i.e., an amount paid is no longer accrued. In the calculation of amounts of
things, differences and sums may generally result in negative numbers, but when
the calculation of the excess of one thing over another results in zero or a
negative number, the calculation is disregarded and an "excess" does not exist.
Portions of things may be expressed as fractions or percentages interchangeably.

         (f) All accounting terms used in an accounting context and not
otherwise defined, and accounting terms partly defined in this Agreement, to the
extent not completely defined, shall be construed in accordance with generally
accepted accounting principles. To the extent that the definitions of accounting
terms in this Agreement are inconsistent with their meanings under generally
accepted accounting principles, the definitions contained in this Agreement
shall control. Capitalized terms used in this Agreement without definition that
are defined in the Uniform Commercial Code are used in this Agreement as defined
in the Uniform Commercial Code.

         (g) In the computation of a period of time from a specified date to a
later specified date or an open-ended period, the words "from" and "beginning"
mean "from and including," the word "after"

                                       38
<PAGE>

means "from but excluding," the words "to" and "until" mean "to but excluding,"
and the word "through" means "to and including." Likewise, in setting deadlines
or other periods, "by" means "by." The words "preceding," "following," and words
of similar import, mean immediately preceding or following. References to a
month or a year refer to calendar months and calendar years.

         (h) Any reference to the enforceability of any agreement against a
party means that it is enforceable, subject as to enforcement against the party,
to applicable bankruptcy, insolvency, reorganization, and other similar laws of
general applicability relating to or affecting creditors' rights and to general
equity principles.

         Section 2.01 Conveyance of Mortgage Loans.

         (a) The Seller, concurrently with the execution and delivery of this
Agreement, hereby transfers to the Depositor, without recourse, all the interest
of the Seller in each Mortgage Loan, including all interest and principal
received or receivable by the Seller on each Mortgage Loan after the Cut-off
Date and all interest and principal payments on each Mortgage Loan received
before the Cut-off Date for installments of interest and principal due after the

Cut-off Date. By the Closing Date, the Seller shall deliver to the Depositor or,
at the Depositor's direction, to the Trustee or other designee of the Depositor,
the Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule
(except that, in the case of Mortgage Loans that are Delay Delivery Mortgage
Loans, such delivery may take place within five Business Days of the Closing
Date) as of the Closing Date. The delivery of the Mortgage Files shall be made
against payment by the Depositor of the purchase price, previously agreed to by
the Seller and Depositor, for the Mortgage Loans. With respect to any Mortgage
Loan that does not have a first payment date on or before the Due Date in the
month of the first Distribution Date, the Seller shall deposit into the
Distribution Account on the first Distribution Account Deposit Date an amount
equal to one month's interest at the related Adjusted Mortgage Rate on the
Cut-off Date Principal Balance of such Mortgage Loan. Also on the Closing Date
the Depositor shall deposit $200 into the Certificate Account for the benefit of
the Class P-1 and Class P-2 Certificates.

         (b) The Depositor, concurrently with the execution and delivery of this
Agreement, hereby transfers to the Trustee for the benefit of the
Certificateholders, without recourse, all the interest of the Depositor in the
Trust Fund, together with the Depositor's right to require the Seller to cure
any breach of a representation or warranty made in this Agreement by the Seller
or to repurchase or substitute for any affected Mortgage Loan in accordance with
this Agreement.

         (c) In connection with the transfer and assignment of each Mortgage
Loan, the Depositor has delivered (or, in the case of the Delay Delivery
Mortgage Loans, will deliver to the Trustee within the time periods specified in
the definition of Delay Delivery Mortgage Loans), for the benefit of the
Certificateholders the following documents or instruments with respect to each
Mortgage Loan so assigned:

                  (i) The original Mortgage Note, endorsed by manual or
         facsimile signature in blank in the following form: "Pay to the order
         of _______________ ______________without recourse," with all
          intervening endorsements showing a complete chain of endorsement from
         the originator to the Person endorsing the Mortgage Note (each
         endorsement being sufficient to transfer all interest of the party so
         endorsing, as noteholder or assignee thereof, in that Mortgage Note) or
         a lost note affidavit for any Lost Mortgage Note from the Seller
         stating that the original Mortgage Note was lost or destroyed, together
         with a copy of the Mortgage Note.

                   (ii) Except as provided below and for each Mortgage Loan that
         is not a MERS Mortgage Loan, the original recorded Mortgage or a copy
         of such Mortgage certified by the Seller as being a true and complete
         copy of the Mortgage (or, in the case of a Mortgage for which the
         related Mortgaged Property is located in the Commonwealth of Puerto
         Rico, a true copy of the Mortgage certified as such by the applicable
         notary) and in the case of each MERS Mortgage Loan, the original
         Mortgage, noting the presence of the MIN of the Mortgage Loans and
         either language indicating that the Mortgage Loan is a MOM Loan if the
         Mortgage Loan is a MOM

                                       40
<PAGE>

         Loan or if the Mortgage Loan was not a MOM Loan at origination, the
         original Mortgage and the assignment thereof to MERS, with evidence of
         recording indicated thereon, or a copy of the Mortgage certified by the
         public recording office in which such Mortgage has been recorded;

                  (iii) In the case of a Mortgage Loan that is not a MERS
         Mortgage Loan, a duly executed assignment of the Mortgage (which may be
         included in a blanket assignment or assignments), together with, except
         as provided below, all interim recorded assignments of the mortgage
         (each assignment, when duly and validly completed, to be in recordable
         form and sufficient to effect the assignment of and transfer to its
         assignee of the Mortgage to which the assignment relates). If the
         related Mortgage has not been returned from the applicable public
         recording office, the assignment of the Mortgage may exclude the
          information to be provided by the recording office. The assignment of
         Mortgage need not be delivered in the case of a Mortgage for which the
         related Mortgage Property is located in the Commonwealth of Puerto
         Rico.

                   (iv) The original or copies of each assumption, modification,
         written assurance, or substitution agreement.

                  (v) Except as provided below, the original or duplicate
         original lender's title policy and all its riders.

                  (vi) The originals of the following documents for each
         Cooperative Loan:

                           (A)       the Co-op Shares, together with a stock
                                    power in blank;

                            (B)       the executed Security Agreement;

                           (C)       the executed Proprietary Lease;

                           (D)       the executed Recognition Agreement;

                           (E)       the executed UCC-1 financing statement that
                                    has been filed in all places required to
                                    perfect the Seller's interest in the Co-op
                                    Shares and the Proprietary Lease with
                                     evidence of recording on it; and

                           (F)       executed UCC-3 financing statements or other
                                    appropriate UCC financing statements
                                    required by state law, evidencing a complete
                                    and unbroken line from the mortgagee to the
                                    Trustee with evidence of recording thereon
                                    (or in a form suitable for recordation).

         In addition, in connection with the assignment of any MERS Mortgage
Loan, the Seller agrees that it will cause, at the Seller's expense, the MERS(R)
System to indicate that the Mortgage Loans sold by the Seller to the Depositor
have been assigned by the Seller to the Trustee in accordance with this
Agreement for the benefit of the Certificateholders by including (or deleting,
in the case of Mortgage Loans that are repurchased in accordance with this
Agreement) in such computer files the information required by the MERS(R) System
to identify the series of the Certificates issued in connection with such
Mortgage Loans. The Seller further agrees that it will not, and will not permit
the Servicer to, and the Servicer agrees that it will not, alter the information
referenced in this paragraph with respect to any Mortgage Loan sold by the
Seller to the Depositor during the term of this Agreement unless and until such
Mortgage Loan is repurchased in accordance with the terms of this Agreement.

                                       41
<PAGE>

         In the event that in connection with any Mortgage Loan that is not a
MERS 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 of clause (ii),
(iii) or (v) above, respectively, concurrently with the execution and delivery
of this Agreement because such document or documents have not been returned from
the applicable public recording office in the case of clause (ii) or (iii)
above, or because the title policy has not been delivered to either the Servicer
or the Depositor by the applicable title insurer in the case of clause (v)
above, then the Depositor shall promptly deliver to the Trustee, in the case of
clause (ii) or (iii) above, the original Mortgage or the interim assignment, as
the case may be, with evidence of recording indicated on when it is received
from the public recording office, or a copy of it, certified, if appropriate, by
the relevant recording office and in the case of clause (v) above, the original
or a copy of a written commitment or interim binder or preliminary report of
title issued by the title insurance or escrow company, with the original or
duplicate copy thereof to be delivered to the Trustee upon receipt thereof. The
delivery of the original Mortgage Loan and each interim assignment or a copy of
them, certified, if appropriate, by the relevant recording office, shall not be
made later than one year following the Closing Date, or, in the case of clause
(v) above, later than 120 days following the Closing Date. If the Depositor is
unable to deliver each Mortgage by that date and each interim assignment because
any documents have not been returned by the appropriate recording office, or, in
the case of each interim assignment, because the related Mortgage has not been
returned by the appropriate recording office, the Depositor shall deliver the
documents to the Trustee as promptly as possible upon their receipt and, in any
event, within 720 days following the Closing Date.

         The Depositor shall forward to the Trustee (a) from time to time
additional original documents evidencing an assumption or modification of a
Mortgage Loan and (b) any other documents required to be delivered by the
Depositor or the Servicer to the Trustee. If the original Mortgage is not
delivered and in connection with the payment in full of the related Mortgage
Loan the public recording office requires the presentation of a "lost
instruments affidavit and indemnity" or any equivalent document, because only a
copy of the Mortgage can be delivered with the instrument of satisfaction or
reconveyance, the Servicer shall execute and deliver the required document to
the public recording office. If a public recording office retains the original
recorded Mortgage or if a Mortgage is lost after recordation in a public
recording office, the Seller shall deliver to the Trustee a copy of the Mortgage
certified by the public recording office to be a true and complete copy of the
original recorded Mortgage.

         As promptly as practicable after any transfer of a Mortgage Loan under
this Agreement, and in any event within thirty days after the transfer, the
Trustee shall (i) affix the Trustee's name to each assignment of Mortgage, as
its assignee, and (ii) 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, if the Trustee has not received the information required
to deliver any assignment of a Mortgage for recording, the Trustee shall deliver
it as soon as practicable after receipt of the needed information and in any
event within thirty days.

          The Trustee need not record any assignment that relates to a Mortgage
Loan (a) the Mortgaged Property and Mortgage File relating to which are located
in California or (b) in any other jurisdiction (including Puerto Rico) under the
laws of which, as evidenced by an Opinion of Counsel delivered by the Seller (at
the Seller's expense) to the Trustee, recording the assignment is not necessary
to protect the Trustee's and the Certificateholders' interest in the related
Mortgage Loan. The Seller shall deliver such Opinion of Counsel within 90 days
of the Closing Date.

         If any Mortgage Loans have been prepaid in full as of the Closing Date,
the Depositor, in lieu of delivering the above documents to the Trustee, will
deposit in the Certificate Account the portion of the prepayment that is
required to be deposited in the Certificate Account pursuant to Section 3.06.

                                       42
<PAGE>

         Notwithstanding anything to the contrary in this Agreement, within five
Business Days after the Closing Date, the Seller shall either

                  (x) deliver to the Trustee the Mortgage File as required
                  pursuant to this Section 2.01 for each Delay Delivery Mortgage
                  Loan or

                  (y) (A) repurchase the Delay Delivery Mortgage Loan or (B)
                  substitute the Substitute Mortgage Loan for a Delay Delivery
                  Mortgage Loan, which repurchase or substitution shall be
                  accomplished in the manner and subject to the conditions in
                  Section 2.03 (treating each such Delay Delivery Mortgage Loan
                  as a Deleted Mortgage Loan for purposes of such Section 2.03);

provided, however, that if the Seller fails to deliver a Mortgage File for any
Delay Delivery Mortgage Loan within the period specified herein, the Seller
shall use its best reasonable efforts to effect a substitution, rather than a
repurchase of, such Deleted Mortgage Loan and provided further that the cure
period provided for in Section 2.02 or in Section 2.03 shall not apply to the
initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but
rather the Seller shall have five (5) Business Days to cure such failure to
deliver. At the end of such period, the Trustee shall send a Delay Delivery
Certification for the Delay Delivery Mortgage Loans delivered during such period
in accordance with the provisions of Section 2.02.

         (d) The Seller agrees to treat the transfer of the Mortgage Loans to
the Depositor as a sale for all tax, accounting, and regulatory purposes.

         (e) The Trust Fund does not intend to acquire or hold any Mortgage Loan
that would violate the representations made by the Seller set forth in clause
(27) of Schedule III.

         Section 2.02 Acceptance by the Trustee of the Mortgage Loans.

         The Trustee acknowledges receipt of the documents identified in the
Initial Certification in the form of Exhibit G-1, and declares that it holds and
will hold such documents and the other documents delivered to it constituting
the Mortgage Files for the Mortgage Loans, and that it 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 will maintain possession of the
related Mortgage Notes in the State of California, unless otherwise permitted by
the Rating Agencies. The Trustee agrees to execute and deliver on the Closing
Date to the Depositor, the Servicer and the Seller an Initial Certification in
the form of Exhibit G-1. Based on its review and examination, and only as to the
documents identified in such Initial Certification, the Trustee acknowledges
that such documents appear regular on their face and relate to such Mortgage
Loans. The Trustee shall be under no duty or obligation to inspect, review or
examine said documents, instruments, certificates or other papers to determine
that the same are genuine, enforceable or appropriate for the represented
purpose or that they have actually been recorded in the real estate records or
that they are other than what they purport to be on their face.

         By the thirtieth day after the Closing Date (or if that day is not a
Business Day, the succeeding Business Day), the Trustee shall deliver to the
Depositor, the Servicer, and the Seller a Delay Delivery Certification with
respect to the Mortgage Loans substantially in the form of Exhibit G-2, with any
applicable exceptions noted thereon.

                                       43
<PAGE>

         By the ninetieth day after the Closing Date (or if that day is not a
Business Day, the succeeding Business Day), the Trustee shall deliver to the
Depositor, the Servicer and the Seller a Final Certification with respect to the
Mortgage Loans in the form of Exhibit H, with any applicable exceptions noted
thereon.

         If, in the course of its review, the Trustee finds any document
constituting a part of a Mortgage File that does not meet the requirements of
Section 2.01, the Trustee shall list such as an exception in the Final
Certification. The Trustee shall not make any determination as to whether (i)
any endorsement is sufficient to transfer all interest of the party so
endorsing, as noteholder or assignee thereof, in 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 any defect that materially and
adversely affects the interests of the Certificateholders within 90 days from
the date it was so notified of the defect and, if the Seller does not correct
the defect within that period, the Seller shall either (a) substitute for the
related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be
accomplished in the pursuant Section 2.03, or (b) purchase the Mortgage Loan at
its Purchase Price from the Trustee within 90 days from the date the Seller was
notified of the defect in writing.

         If a substitution or purchase of a Mortgage Loan pursuant to this
provision is required because of a delay in delivery of any documents by the
appropriate recording office, or there is a dispute between either the Servicer
or the Seller and the Trustee over the location or status of the recorded
document, then the substitution or purchase shall occur within 720 days from the
Closing Date. In no other case may a substitution or purchase occur more than
540 days from the Closing Date.

         Any substitution pursuant to (a) above or purchase pursuant to (b)
above shall not be effected before the delivery to the Trustee of the Opinion of
Counsel, if required by Section 2.05, and any substitution pursuant to (a) above
shall not be effected before the additional delivery to the Trustee of a Request
for Release substantially in the form of Exhibit N. No substitution is permitted
to be made in any calendar month after the Determination Date for the month.

         The Purchase Price for any Mortgage Loan shall be deposited by the
Seller in the Certificate Account by the Distribution Account Deposit Date for
the Distribution Date in the month following the month of repurchase and, upon
receipt of the deposit and certification with respect thereto in the form of
Exhibit N, the Trustee shall release the related Mortgage File to the Seller and
shall execute and deliver at the Seller's request any instruments of transfer or
assignment prepared by the Seller, in each case without recourse, necessary to
vest in the Seller, or a designee, the Trustee's interest in any Mortgage Loan
released pursuant hereto.

         If pursuant to the foregoing provisions the Seller repurchases a
Mortgage Loan that is a MERS Mortgage Loan, the Servicer shall either (i) 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 or (ii) cause MERS to designate on the MERS(R) System the
Seller as the beneficial holder of such Mortgage Loan.

         The Trustee shall retain possession and custody of each Mortgage File
in accordance with and subject to the terms and conditions set forth herein. The
Servicer shall promptly deliver to the Trustee, upon the execution or receipt
thereof, the originals of any other documents or instruments constituting the
Mortgage File that come into the possession of the Servicer from time to time.

                                       44
<PAGE>

         The obligation of the Seller to substitute for or to purchase any
Mortgage Loan that does not meet the requirements of Section 2.01 shall
constitute the sole remedy respecting the defect available to the Trustee, the
Depositor, and any Certificateholder against the Seller.

         Section 2.03 Representations, Warranties, and Covenants of the Seller
and the Servicer.

         (a) IndyMac, in its capacities as Seller and Servicer, makes the
representations and warranties in Schedule II, and by this reference
incorporated in this Agreement, to the Depositor and the Trustee, as of the
Closing Date.

         (b) The Seller, in its capacity as Seller, makes the representations
and warranties in Schedule III, and by this reference incorporated in this
Agreement, to the Depositor and the Trustee, as of the Closing Date, or if so
specified in Schedule III, as of the Cut-off Date.

         (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty made pursuant to Section 2.03(b) 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. Any breach of representations and warranties under clauses (27) and
(32) of Schedule III shall be deemed to affect materially and adversely the
interests of the Certificateholders in the affected Mortgage Loans. The Seller
covenants that within 90 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
pursuant to Section 2.03(b) which materially and adversely affects the interests
of the Certificateholders in any Mortgage Loan, it shall cure such breach in all
material respects, and if such breach is not so cured, shall, (i) if the 90-day
period expires before the second anniversary of the Closing Date, remove the
Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and substitute in
its place a Substitute Mortgage Loan, in accordance with this Section 2.03; or
(ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at
the Purchase Price in the manner set forth below. Any substitution pursuant to
(i) above shall not be effected before the delivery to the Trustee of the
Opinion of Counsel, if required by Section 2.05, and a Request for Release
substantially in the form of Exhibit N, and the Mortgage File for any Substitute
Mortgage Loan. The Seller shall promptly reimburse the Servicer and the Trustee
for any expenses reasonably incurred by the Servicer or the Trustee in respect
of enforcing the remedies for the breach.

         With respect to any 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, 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 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 Servicer shall amend the Mortgage Loan Schedule for the benefit of
the Certificateholders to reflect the removal of the Deleted Mortgage Loan and
the substitution of the Substitute Mortgage Loans and the Servicer shall deliver
the amended Mortgage Loan Schedule to the Trustee. Upon the substitution, the
Substitute Mortgage Loans shall be subject to this Agreement in all respects,
and the Seller shall be deemed to have made with respect to the Substitute
Mortgage Loans, as of the date of substitution, the representations and
warranties made pursuant to Section 2.03(b) with respect to the Mortgage Loan.
Upon any substitution and the deposit to the Certificate Account of the amount
required

                                       45
<PAGE>

to be deposited therein in connection with the substitution as described in the
following paragraph, the Trustee shall release the Mortgage File held for the
benefit of the Certificateholders relating to the 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 Substitute
Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will
determine the amount (if any) by which the aggregate principal balance of all
such 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, if the Seller is not the Servicer, an amount equal to
the aggregate of any unreimbursed Advances and Servicer Advances with respect to
such Deleted Mortgage Loans shall be deposited into the Certificate Account by
the Seller by the Distribution Account Deposit Date for the Distribution Date in
the month succeeding the calendar month during which the related Mortgage Loan
became required to be purchased or replaced hereunder. If the Seller repurchases
a Mortgage Loan, the Purchase Price therefor shall be deposited in the
Certificate Account pursuant to Section 3.06 by the Distribution Account Deposit
Date for the Distribution Date in the month following the month during which the
Seller became obligated hereunder to repurchase or replace the Mortgage Loan and
upon such deposit of the Purchase Price and receipt of a Request for Release in
the form of Exhibit N, 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. The obligation under this
Agreement of any Person to cure, repurchase, or replace any Mortgage Loan as to
which a breach has occurred and is continuing shall constitute the sole remedy
against the Person respecting the 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 and shall not be waived by the Depositor.

         The Seller assigns to the Depositor and the Depositor assigns to the
Trustee all rights the Seller might have under contracts with third parties
relating to early payment defaults on the Mortgage Loans ("EPD Rights") and the
Servicer assumes any related duties as part of its servicing obligations.
Consistent with the Servicing Standard, the Servicer shall attempt to enforce
the EPD rights. If the Servicer's enforcement of the EPD Rights obligates the
Servicer to sell a Mortgage Loan to a third party, the Servicer shall repurchase
the Mortgage Loan at the Purchase Price and sell the Mortgage Loan to the third
party, provided however, in no case shall the Servicer be obligated to
repurchase a Mortgage Loan on account of EPD Rights unless and until the
Servicer shall have previously received repurchase payment from a third party.
The Servicer shall deposit into the Certificate Account all amounts received in
connection with the enforcement of EPD Rights, not exceeding the Purchase Price,
with respect to any Mortgage Loan. Any amounts received by the Servicer with
respect a Mortgage Loan in excess of the Purchase Price shall be retained by the
Servicer as additional servicing compensation. The Trustee, upon receipt of
certification from the Servicer of the deposit of the Purchase Price in
connection with a repurchase of a Mortgage Loan and a Request for File Release
from the Servicer, shall release or cause to be released to the purchaser of
such Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such Mortgage
Loan, in each case without recourse, as shall be necessary to vest in the
purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and
the purchaser of such Mortgage Loan shall succeed to all the

                                        46
<PAGE>

Trustee's right, title and interest in and to such Mortgage Loan and all
security and documents related thereto. Such assignment shall be an assignment
outright and not for security. The purchaser of such Mortgage Loan shall
thereupon own such Mortgage Loan, and all security and documents, free of any
further obligation to the Trustee or the Certificateholders with respect
thereto.

         Section 2.04 Representations and Warranties of the Depositor as to the
Mortgage Loans.

         The Depositor represents and warrants to the Trustee with respect to
each Mortgage Loan as of the date of this Agreement or such other date set forth
in this Agreement that as of the Closing Date, and following the transfer of the
Mortgage Loans to it by the Seller, the Depositor had good title to the Mortgage
Loans and the Mortgage Notes were subject to no offsets, defenses, or
counterclaims.

         The representations and warranties in this Section 2.04 shall survive
delivery of the Mortgage Files to the Trustee. Upon discovery by the Depositor
or the Trustee of any breach of any of the representations and warranties in
this Section that materially and adversely affects the interest of the
Certificateholders, the party discovering the breach shall give prompt written
notice to the others and to each Rating Agency.

         Section 2.05 Delivery of Opinion of Counsel in Connection with
Substitutions.

         (a) Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 or 2.03 shall be made more than 90 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 860G(d) of the Code, respectively or (ii)
cause any REMIC created under this Agreement to fail to qualify as a REMIC at
any time that any Certificates are outstanding.

         (b) Upon discovery by the Depositor, the Seller, the Servicer or the
Trustee that any Mortgage Loan does not constitute a "qualified mortgage" within
the meaning of section 860G(a)(3) of the Code, the party discovering such fact
shall promptly (and in any event within five Business Days of discovery) give
written notice thereof to the other parties. In connection therewith, the
Trustee shall require the Seller, at the Seller's option, to either (i)
substitute, if the conditions in Section 2.03(c) with respect to substitutions
are satisfied, a Substitute Mortgage Loan for the affected Mortgage Loan, or
(ii) repurchase the affected Mortgage Loan within 90 days of such discovery in
the same manner as it would a Mortgage Loan for a breach of representation or
warranty made pursuant to Section 2.03. The Trustee shall reconvey to the Seller
the Mortgage Loan to be released pursuant hereto in the same manner, and on the
same terms and conditions, as it would a Mortgage Loan repurchased for breach of
a representation or warranty contained in Section 2.03.

         Section 2.06 Execution and Delivery of Certificates.

         The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, 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.

         Section 2.07 REMIC Matters.

         The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
under this Agreement. The "Startup Day" for purposes of the REMIC Provisions
shall be the Closing Date. Each REMIC's fiscal year shall be the calendar year.

                                 ARTICLE THREE

                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

         Section 3.01 Servicer to Service Mortgage Loans.

         For and on behalf of the Certificateholders, the Servicer shall service
and administer the Mortgage Loans in accordance with this Agreement and the
Servicing Standard.

         The Servicer shall not make or permit any modification, waiver, or
amendment of any term of any Mortgage Loan that would cause any REMIC created
under this Agreement to fail to qualify as a REMIC or result in the imposition
of any tax under section 860F(a) or section 860G(d) of the Code.

         Without limiting the generality of the foregoing, the 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 the 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 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. The Servicer shall prepare and deliver to the Depositor or
the Trustee any documents requiring execution and delivery by either or both of
them appropriate to enable the Servicer to service and administer the Mortgage
Loans to the extent that the Servicer is not permitted to execute and deliver
such documents pursuant to the preceding sentence. Upon receipt of the
documents, the Depositor or the Trustee shall execute the documents and deliver
them to the Servicer.

         The Servicer further is authorized and empowered by the Trustee, on
behalf of the Certificateholders and the Trustee, in its own name, when the
Servicer believes it 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.

         In accordance with and to the extent of the Servicing Standard, the
Servicer shall advance funds necessary to effect the payment of taxes and
assessments on the Mortgaged Properties, which advances shall be reimbursable in
the first instance from related collections from the Mortgagors pursuant to
Section 3.07, and further as provided in Section 3.09. The costs incurred by the
Servicer 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 to the
Stated Principal Balances of the related Mortgage Loans, notwithstanding that
the Mortgage Loans so permit.

          Nothing in this Agreement to the contrary shall limit the Servicer from
undertaking any legal action that it may deem appropriate with respect to the
Mortgage Loans including, without limitation, any rights or causes of action
arising out of the origination of the Mortgage Loans.

         Section 3.02 [Reserved].

         Section 3.03 Rights of the Depositor and the Trustee in Respect of the
Servicer.

         The Depositor may, but is not obligated to, enforce the obligations of
the Servicer under this Agreement and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of the Servicer under this
Agreement and in connection with any such defaulted obligation to exercise the
related rights of the Servicer under this Agreement; provided that the Servicer
shall not be relieved of any of its obligations under this Agreement by virtue
of such performance by the Depositor or its designee. Neither the Trustee nor
the Depositor shall have any responsibility or liability for any action or
failure to act by the Servicer nor shall the Trustee or the Depositor be
obligated to supervise the performance of the Servicer under this Agreement or
otherwise.

         Section 3.04 [Reserved].

         Section 3.05 Trustee to Act as Servicer.

         If the Servicer for any reason is no longer the Servicer under this
Agreement (including because of the occurrence or existence of an Event of
Default or termination by the Depositor), the Trustee or its successor shall
assume all of the rights and obligations of the Servicer under this Agreement
arising thereafter (except that the Trustee shall not be

         (i) liable for losses of the Servicer pursuant to Section 3.10 or any
acts or omissions of the predecessor Servicer hereunder,

         (ii) obligated to make Advances if it is prohibited from doing so by
applicable law,

         (iii) obligated to effectuate repurchases or substitutions of Mortgage
Loans hereunder, including repurchases or substitutions pursuant to Section 2.02
or 2.03,

         (iv) responsible for expenses of the Servicer pursuant to Section 2.03,
or

         (v) deemed to have made any representations and warranties of the
Servicer hereunder). Any assumption shall be subject to Section 7.02.

         Notwithstanding anything else in this Agreement to the contrary, in no
event shall the Trustee be liable for any servicing fee or for any differential
in the amount of the Servicing Fee paid under this Agreement and the amount
necessary to induce any successor Servicer to act as successor Servicer under
this Agreement and the transactions provided for in this Agreement.

         Section 3.06 Collection of Mortgage Loan Payments; Certificate Account;
Distribution Account.

         (a) In accordance with and to the extent of the Servicing Standard, the
Servicer shall make reasonable efforts in accordance with the customary and
usual standards of practice of prudent mortgage servicers to collect all
payments called for under the Mortgage Loans to the extent the procedures are
consistent with this Agreement and any related Required Insurance Policy.
Consistent with the foregoing, the Servicer may in its discretion (i) waive any
late payment charge or, subject to Section 3.20, any Prepayment Charge in
connection with the prepayment of a Mortgage Loan and (ii) extend the due dates
for payments due on a Delinquent Mortgage Loan for a period not greater than 125
days. In connection with a seriously delinquent or defaulted Mortgage Loan, the
Servicer may, consistent with the Servicing

                                       50
<PAGE>

Standard, waive, modify or vary any term of that Mortgage Loan (including
modifications that change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of that Mortgage Loan ), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of that Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor if in the Servicer's determination such waiver,
modification, postponement or indulgence is not materially adverse to the
interests of the Certificateholders (taking into account any estimated loss that
might result absent such action) and is expected to minimize the loss on such
Mortgage Loan; provided, however, the Servicer shall not initiate new lending to
such Mortgagor through the Trust and cannot, except as provided in the
immediately succeeding sentence, extend the maturity of any Mortgage Loan past
the date on which the final payment is due on the latest maturing Mortgage Loan
as of the Cut-off Date. With respect to no more than 5% of the Mortgage Loans
(measured by aggregate Cut-off Date Principal Balance of the Mortgage Loans),
the Servicer may extend the maturity of a Mortgage Loan past the date on which
the final payment is due on the latest maturing Mortgage Loan as of the Cut-off
Date, but in no event more than one year past such date. In the event of any
such arrangement, the Servicer shall make Advances on the related Mortgage Loan
in accordance with Section 4.01 during the scheduled period in accordance with
the amortization schedule of the Mortgage Loan without modification thereof
because of the arrangements. The 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 the payment is required is prohibited by applicable law. The Servicer
shall not have the discretion to sell any Delinquent or defaulted Mortgage Loan.

         (b) [Reserved.]

         (c) [Reserved.]

         (d) The Servicer shall establish and maintain a Certificate Account
into which the Servicer shall deposit on a daily basis (i) within two Business
Days of receipt (in the case of items (i) through (iii) below) and (2) within
one Business Day of receipt (in the case of all other items), except as
otherwise specified herein, the following payments and collections received by
it in respect of Mortgage Loans after the Cut-off Date (other than in respect of
principal and interest due on the Mortgage Loans by the Cut-off Date) and the
following amounts required to be deposited hereunder:

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

                  (ii) all payments on account of interest on the Mortgage
         Loans, net of the Servicing Fee;

                  (iii) all Insurance Proceeds, Subsequent Recoveries and
         Liquidation Proceeds, other than proceeds to be applied to the
         restoration or repair of the Mortgaged Property or released to the
         Mortgagor in accordance with the Servicer's normal servicing
         procedures;

                   (iv) any amount required to be deposited by the Servicer
         pursuant to Section 3.06(f) in connection with any losses on Permitted
         Investments;

                  (v) any amounts required to be deposited by the Servicer
         pursuant to Sections 3.10 and 3.12;

                                       51
<PAGE>

                  (vi) all Purchase Prices from the Servicer or Seller and all
         Substitution Adjustment Amounts;

                  (vii) all Advances made by the Servicer pursuant to Section
         4.01;

                  (viii) any other amounts required to be deposited under this
         Agreement; and

                  (ix) all Prepayment Charges collected.

         In addition, with respect to any Mortgage Loan that is subject to a
buydown agreement, on each Due Date for the Mortgage Loan, in addition to the
monthly payment remitted by the Mortgagor, the Servicer shall cause funds to be
deposited into the Certificate Account in an amount required to cause an amount
of interest to be paid with respect to the Mortgage Loan equal to the amount of
interest that has accrued on the Mortgage Loan from the preceding Due Date at
the Mortgage Rate net of the Servicing Fee Rate on that date.

         The foregoing requirements for remittance by the Servicer shall be
exclusive, it being understood and agreed that, without limiting the generality
of the foregoing, payments in the nature of late payment charges or assumption
fees, if collected, need not be remitted by the Servicer. If the Servicer remits
any amount not required to be remitted, it may at any time withdraw that amount
from the Certificate Account, any provision in this Agreement to the contrary
notwithstanding. The withdrawal or direction may be accomplished by delivering
written notice of it to the Trustee or any other institution maintaining the
Certificate Account that describes the amounts deposited in error in the
Certificate Account. The Servicer shall maintain adequate records with respect
to all withdrawals made pursuant to this Section 3.06. All funds deposited in
the Certificate Account shall be held in trust for the Certificateholders until
withdrawn in accordance with Section 3.09.

         (e) The Trustee shall establish and maintain the Distribution Account
on behalf of the Certificateholders. The Trustee shall, promptly upon receipt,
deposit in the Distribution Account and retain in the Distribution Account the
following:

                  (i) the aggregate amount remitted by the Servicer to the
         Trustee pursuant to Section 3.09(a);

                  (ii) any amount deposited by the Servicer pursuant to Section
         3.06(f) in connection with any losses on Permitted Investments; and

                  (iii) any other amounts deposited under this Agreement that
         are required to be deposited in the Distribution Account.

         If the Servicer remits any amount not required to be remitted, it may
at any time direct the Trustee in writing to withdraw that amount from the
Distribution Account, any provision in this Agreement to the contrary
notwithstanding. The direction may be accomplished by delivering an Officer's
Certificate to the Trustee that describes the amounts deposited in error in the
Distribution Account. All funds deposited in the Distribution 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 3.09. In
no event shall the Trustee incur liability for withdrawals from the Distribution
Account at the direction of the Servicer.

         (f) Each institution at which the Certificate Account is maintained
shall invest the funds in such account as directed in writing by the Servicer in
Permitted Investments, which shall mature not later than

                                       52
<PAGE>

the second Business Day preceding the related Distribution Account Deposit Date
(except that if the Permitted Investment is an obligation of the institution
that maintains the account, then the Permitted Investment shall mature not later
than the Business Day preceding the Distribution Account Deposit Date) and which
shall not be sold or disposed of before its maturity. The funds in the
Distribution Account shall remain uninvested. All such Permitted Investments
shall be made in the name of the Trustee, for the benefit of the
Certificateholders. All income realized from any such investment of funds on
deposit in the Certificate Account shall be for the benefit of the Servicer as
servicing compensation and shall be remitted to it monthly as provided in this
Agreement. The amount of any realized losses on Permitted Investments in the
Certificate Account shall promptly be deposited by the Servicer in the
Certificate Account. The Trustee shall not be liable for the amount of any loss
incurred in respect of any investment or lack of investment of funds held in the
Certificate Account and made in accordance with this Section 3.06.

         (g) The Servicer shall give notice to the Trustee, the Seller, each
Rating Agency and the Depositor of any proposed change of the location of the
Certificate Account not later than 30 days and not more than 45 days prior to
any change of this Agreement. The Trustee shall give notice to the Servicer, the
Seller, each Rating Agency and the Depositor of any proposed change of the
location of the Distribution Account not later than 30 days and not more than 45
days prior to any change of this Agreement.

         Section 3.07 Collection of Taxes, Assessments and Similar Items; Escrow
Accounts.

         (a) To the extent required by the related Mortgage Note and not
violative of current law, the Servicer shall establish and maintain one or more
accounts (each, an "Escrow Account") and deposit and retain therein all
collections from the Mortgagors (or advances) for the payment of taxes,
assessments, hazard insurance premiums or comparable items for the account of
the Mortgagors. Nothing herein shall require the Servicer to compel a Mortgagor
to establish an Escrow Account in violation of applicable law.

         (b) Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
(without duplication) the Servicer out of related collections for any payments
made pursuant to Section 3.01 (with respect to taxes and assessments and
insurance premiums) and Section 3.10 (with respect to hazard insurance), to
refund to any Mortgagors any sums determined to be overages, to pay interest, if
required by law or the related Mortgage or Mortgage Note, to Mortgagors on
balances in the Escrow Account or to clear and terminate the Escrow Account at
the termination of this Agreement in accordance with Section 9.01. The Escrow
Accounts shall not be a part of the Trust Fund.

         (c) The Servicer shall advance any payments referred to in Section
3.07(a) that are not timely paid by the Mortgagors or advanced by the Servicer
on the date when the tax, premium or other cost for which such payment is
intended is due, but the Servicer shall be required so to advance only to the
extent that such advances, in the good faith judgment of the Servicer, will be
recoverable by the Servicer out of Insurance Proceeds, Liquidation Proceeds or
otherwise.

         Section 3.08 Access to Certain Documentation and Information Regarding
the Mortgage Loans.

         The 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 the Servicer.

                                       53
<PAGE>

         Upon reasonable advance notice in writing, the Servicer will provide to
each Certificateholder or Certificate Owner that is a savings and loan
association, bank, or insurance company certain reports and reasonable access to
information and documentation regarding the Mortgage Loans sufficient to permit
the Certificateholder or Certificate Owner to comply with applicable regulations
of the OTS or other regulatory authorities with respect to investment in the
Certificates. The Servicer shall be entitled to be reimbursed by each such
Certificateholder or Certificate Owner for actual expenses incurred by the
Servicer in providing the reports and access.

          Section 3.09 Permitted Withdrawals from the Certificate Account and the
Distribution Account.

         (a) The Servicer may (and, in the case of clause (ix) below, shall)
from time to time make withdrawals from the Certificate Account for the
following purposes:

                  (i) to pay to the Servicer (to the extent not previously
         retained) the servicing compensation to which it is entitled pursuant
         to Section 3.15, and to pay to the Servicer, as additional servicing
         compensation, earnings on or investment income with respect to funds in
         or credited to the Certificate Account;

                  (ii) to reimburse the Servicer or successor Servicer for the
         unreimbursed Advances made by it, such right of reimbursement pursuant
         to this subclause (ii) being limited to amounts received on the
         Mortgage Loans in respect of which the Advance was made;

                  (iii) to reimburse the Servicer or successor Servicer for any
         Nonrecoverable Advance previously made by it;

                  (iv) to reimburse the Servicer for Insured Expenses from the
         related Insurance Proceeds;

                  (v) to reimburse the Servicer for (a) unreimbursed Servicing
         Advances, the Servicer's right to reimbursement pursuant to this clause
         (a) with respect to any Mortgage Loan being limited to amounts received
         on the Mortgage Loans that represent late recoveries of the payments
         for which the advances were made pursuant to Section 3.01 or Section
         3.07, (b) unreimbursed Servicing Advances made in respect of a Mortgage
         Loan for which such Servicing Advances are not recoverable from the
         Mortgagor and (c) for unpaid Servicing Fees as provided in Section
         3.12;

                  (vi) to pay to the purchaser, with respect to each Mortgage
         Loan or property acquired in respect of such Mortgage Loan that has
         been purchased pursuant to Section 2.02, 2.03, or 3.12, all amounts
         received thereon after the date of such purchase;

                  (vii) to reimburse the Seller, the Servicer, or the Depositor
         for expenses incurred by any of them and reimbursable pursuant to
         Section 6.03;

                   (viii) to withdraw any amount deposited in the Certificate
         Account and not required to be deposited in the Certificate Account;

                  (ix) by the Distribution Account Deposit Date, to withdraw (1)
         the Available Funds and the Trustee Fee for the Distribution Date, to
         the extent on deposit, and (2) the Prepayment Charges on deposit, and
         remit such amount to the Trustee for deposit in the Distribution
         Account; and

                                        54
<PAGE>

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

         The Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, to justify any withdrawal from the Certificate
Account pursuant to subclauses (i), (ii), (iv), (v), and (vi). Before making any
withdrawal from the Certificate Account pursuant to subclause (iii), the
Servicer shall deliver to the Trustee an Officer's Certificate of a Servicing
Officer indicating the amount of any previous Advance determined by the Servicer
to be a Nonrecoverable Advance and identifying the related Mortgage Loans and
their respective portions of the Nonrecoverable Advance.

         (b) The Trustee shall withdraw funds from the Distribution Account for
distributions to Certificateholders 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 third paragraph of Section 8.11). In
addition, the Trustee may from time to time make withdrawals from the
Distribution Account for the following purposes:

         (i) to pay to itself the Trustee Fee for the related Distribution Date;

         (ii) to withdraw and return to the Servicer any amount deposited in the
Distribution Account and not required to be deposited therein; and

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

         Section 3.10 Maintenance of Hazard Insurance; Maintenance of Primary
Insurance Policies.

         (a) The Servicer shall maintain, for each Mortgage Loan, hazard
insurance with extended coverage in an amount that is at least equal to the
lesser of

         (i) the maximum insurable value of the improvements securing the
Mortgage Loan and

         (ii) the greater of (y) the outstanding principal balance of the
Mortgage Loan and (z) an amount such that the proceeds of the policy are
sufficient to prevent the Mortgagor or the mortgagee from becoming a co-insurer.

         Each policy of standard hazard insurance shall contain, or have an
accompanying endorsement that contains, a standard mortgagee clause. Any amounts
collected under the policies (other than the amounts to be applied to the
restoration or repair of the related Mortgaged Property or amounts released to
the Mortgagor in accordance with the Servicer's normal servicing procedures)
shall be deposited in the Certificate Account. Any cost incurred in maintaining
any insurance shall not, for the purpose of calculating monthly distributions to
the Certificateholders or remittances to the Trustee for their benefit, be added
to the principal balance of the Mortgage Loan, notwithstanding that the Mortgage
Loan so permits. Such costs shall be recoverable by the Servicer out of late
payments by the related Mortgagor or out of Liquidation Proceeds to the extent
permitted by Section 3.09. No earthquake or other additional insurance is to be
required of any Mortgagor or maintained on property acquired in respect of a
Mortgage other than pursuant to any applicable laws and regulations in force
that require additional insurance. If the Mortgaged Property is located at the
time of origination of the Mortgage Loan in a federally designated special flood
hazard area and the area is participating in the national flood insurance
program, the Servicer shall maintain flood insurance for the Mortgage Loan. The
flood insurance shall be in an amount equal to the least of (i) the original
principal balance of the related Mortgage Loan, (ii) the

                                       55
<PAGE>

replacement value of the improvements that are part of the Mortgaged Property,
and (iii) the maximum amount of flood insurance available for the related
Mortgaged Property under the national flood insurance program.

         If the Servicer obtains and maintains a blanket policy insuring against
hazard losses on all of the Mortgage Loans, it shall have satisfied its
obligations in the first sentence of this Section 3.10. The policy may contain a
deductible clause on terms substantially equivalent to those commercially
available and maintained by comparable servicers. If the policy contains a
deductible clause and a policy complying with the first sentence of this Section
3.10 has not been maintained on the related Mortgaged Property, and if a loss
that would have been covered by the required policy occurs, the Servicer shall
deposit in the Certificate Account, without any right of reimbursement, the
amount not otherwise payable under the blanket policy because of the deductible
clause. In connection with its activities as Servicer of the Mortgage Loans, the
Servicer agrees to present, on behalf of itself, the Depositor, and the Trustee
for the benefit of the Certificateholders, claims under any blanket policy.

         (b) The Servicer shall not take any action that would result in
non-coverage under any applicable Primary Insurance Policy of any loss that, but
for the actions of the Servicer, would have been covered thereunder. The
Servicer shall not cancel or refuse to renew any Primary Insurance Policy that
is in effect at the date of the initial issuance of the Certificates and is
required to be kept in force hereunder unless the replacement Primary Insurance
Policy for the canceled or non-renewed policy is maintained with a Qualified
Insurer. The Servicer need not maintain any Primary Insurance Policy if
maintaining the Primary Insurance Policy is prohibited by applicable law. The
Servicer agrees, to the extent permitted by applicable law, to effect the timely
payment of the premiums on each Primary Insurance Policy, and any costs not
otherwise recoverable shall be recoverable by the Servicer from the related
liquidation proceeds.

         In connection with its activities as Servicer of the Mortgage Loans,
the Servicer agrees to present, on behalf of itself, the Trustee and the
Certificateholders, claims to the insurer under any Primary Insurance Policies
and, in this regard, to take any reasonable action in accordance with the
Servicing Standard necessary to permit recovery under any Primary Insurance
Policies respecting defaulted Mortgage Loans. Any amounts collected by the
Servicer under any Primary Insurance Policies shall be deposited in the
Certificate Account.

         Section 3.11 Enforcement of Due-On-Sale Clauses; Assumption Agreements.

         (a) Except as otherwise provided in this Section 3.11, when any
property subject to a Mortgage has been conveyed by the Mortgagor, the Servicer
shall to the extent that it has knowledge of the conveyance and in accordance
with the Servicing Standard, enforce any due-on-sale clause contained in any
Mortgage Note or Mortgage, to the extent permitted under applicable law and
governmental regulations, but only to the extent that enforcement will not
adversely affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Servicer is not required to exercise these
rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
conditions contained in the Mortgage Note and Mortgage related thereto and the
consent of the mortgagee under the Mortgage Note or Mortgage is not otherwise so
required under the Mortgage Note or Mortgage as a condition to the transfer.

         If (i) the Servicer is prohibited by law from enforcing any due-on-sale
clause, (ii) coverage under any Required Insurance Policy would be adversely
affected, (iii) the Mortgage Note does not include a due-on-sale clause, or (iv)
nonenforcement is otherwise permitted hereunder, the Servicer is authorized,
subject to Section 3.11(b), to take or enter into an assumption and modification
agreement from or with the person to whom the property has been or is about to
be conveyed, pursuant to which the person becomes liable under the Mortgage Note
and, unless prohibited by applicable state law, the Mortgagor

                                        56
<PAGE>

remains liable thereon. The Mortgage Loan must continue to be covered (if so
covered before the Servicer enters into the agreement) by the applicable
Required Insurance Policies.

         The Servicer, subject to Section 3.11(b), is also authorized with the
prior approval of the insurers under any Required Insurance Policies to enter
into a substitution of liability agreement with the Person, pursuant to which
the original Mortgagor is released from liability and the Person is substituted
as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the
foregoing, the Servicer shall not be deemed to be in default under this Section
3.11 because of any transfer or assumption that the Servicer reasonably believes
it is restricted by law from preventing, for any reason whatsoever.

         (b) Subject to the Servicer's duty to enforce any due-on-sale clause to
the extent set forth in Section 3.11(a), in any case in which a Mortgaged
Property has been conveyed to a Person by a Mortgagor, and the 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, the Servicer shall prepare and
deliver to the Trustee for signature and shall direct the Trustee, in writing,
to execute the assumption agreement with the Person to whom the Mortgaged
Property is to be conveyed, and the modification agreement or supplement to the
Mortgage Note or Mortgage or other instruments appropriate 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 the Person. In connection with any such assumption, no material term of the
Mortgage Note may be changed.

         In addition, the substitute Mortgagor and the Mortgaged Property must
be acceptable to the Servicer in accordance with its underwriting standards as
then in effect. Together with each substitution, assumption, or other agreement
or instrument delivered to the Trustee for execution by it, the Servicer shall
deliver an Officer's Certificate signed by a Servicing Officer stating that the
requirements of this subsection have been met in connection with such Officer's
Certificate. The Servicer shall notify the Trustee that any substitution or
assumption agreement has been completed by forwarding to the Trustee the
original of the 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 the Mortgage File to the same extent as all
other documents and instruments constituting a part of the Mortgage File. The
Servicer will retain any fee collected by it for entering into an assumption or
substitution of liability agreement as additional servicing compensation.

         Section 3.12 Realization Upon Defaulted Mortgage Loans.

         The Servicer shall use reasonable efforts in accordance with the
Servicing Standard to foreclose on or otherwise comparably convert the ownership
of assets securing such of the Mortgage Loans as come into and continue in
default and as to which no satisfactory arrangements can be made for collection
of delinquent payments. In connection with the foreclosure or other conversion,
the Servicer shall follow the Servicing Standard and shall follow the
requirements of the insurer under any Required Insurance Policy. The Servicer
shall not be required to expend its own funds in connection with any foreclosure
or towards the restoration of any property unless it determines (i) that the
restoration or foreclosure will increase the proceeds of liquidation of the
Mortgage Loan after reimbursement to itself of restoration expenses and (ii)
that restoration expenses will be recoverable to it through Liquidation Proceeds
(respecting which it shall have priority for purposes of withdrawals from the
Certificate Account). The Servicer shall be responsible for all other costs and
expenses incurred by it in any foreclosure proceedings. The Servicer is entitled
to reimbursement of such costs and expenses from the liquidation proceeds with
respect to the related Mortgaged Property, as provided in the definition of
Liquidation Proceeds. If the Servicer has knowledge that a Mortgaged Property
that the Servicer is contemplating

                                       57
<PAGE>

acquiring in foreclosure or by deed in lieu of foreclosure is located within a
one mile radius of any site listed in the Expenditure Plan for the Hazardous
Substance Clean Up Bond Act of 1984 or other site with environmental or
hazardous waste risks known to the Servicer, the Servicer will, before acquiring
the Mortgaged Property, consider the risks and only take action in accordance
with its established environmental review procedures.

         With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the Trustee for the benefit of the Certificateholders,
or its nominee, on behalf of the Certificateholders. The Trustee's name shall be
placed on the title to the REO Property solely as the Trustee hereunder and not
in its individual capacity. The Servicer shall ensure that the title to the REO
Property references the Pooling and Servicing Agreement and the Trustee's
capacity hereunder. Pursuant to its efforts to sell the REO Property, the
Servicer shall either itself or through an agent selected by the Servicer
protect and conserve the REO Property in accordance with the Servicing Standard.

         The 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, if required by
section 6050P of the Code with respect to the cancellation of indebtedness by
certain financial entities, by preparing any required tax and information
returns, in the form required.

         If the Trust Fund acquires any Mortgaged Property as aforesaid or
otherwise in connection with a default or imminent default on a Mortgage Loan,
the REO Property shall only be held temporarily, shall be actively marketed for
sale, and the Servicer shall dispose of the Mortgaged Property as soon as
practicable, and in any case before the end of the third calendar year following
the calendar year in which the Trust Fund acquires the property. 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 behalf of the Trust Fund.

         The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of the
foreclosure would exceed the costs and expenses of bringing a foreclosure
proceeding. The proceeds received from the maintenance of any REO Properties,
net of reimbursement to the Servicer for costs incurred (including any property
or other taxes) in connection with maintenance of the REO Properties and net of
unreimbursed Servicing Fees, Advances, and Servicing Advances, shall be applied
to the payment of principal of and interest on the related defaulted Mortgage
Loans (with interest accruing as though the Mortgage Loans were still current
and adjustments, if applicable, to the Mortgage Rate were being made in
accordance with the Mortgage Note) and all such proceeds 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
Certificate Account. To the extent the net proceeds received during any calendar
month exceeds the amount attributable to amortizing principal and accrued
interest at the related Mortgage Rate on the related Mortgage Loan for the
calendar month, the excess shall be considered to be a partial prepayment of
principal of the related Mortgage Loan.

         The proceeds from any liquidation of a Mortgage Loan, as well as any
proceeds from an REO Property, will be applied in the following order of
priority: first, to reimburse the Servicer for any related unreimbursed
Servicing Advances or Servicing Fees or for any related unreimbursed Advances,
as applicable; second, to reimburse the Servicer, as applicable, and to
reimburse the Certificate Account for any Nonrecoverable Advances (or portions
thereof) that were previously withdrawn by the Servicer pursuant to Section
3.09(a)(iii) that related to the Mortgage Loan; third, 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 Adjusted Net Mortgage Rate to the Due Date occurring in

                                       58
<PAGE>

the month in which such amounts are required to be distributed; and fourth, as a
recovery of principal of the Mortgage Loan. The Servicer will retain any Excess
Proceeds from the liquidation of a Liquidated Mortgage Loan as additional
servicing compensation pursuant to Section 3.15.

         The Servicer may agree to a modification of any Mortgage Loan at the
request of the related Mortgagor if (i) the modification is in lieu of a
refinancing and (ii) the Servicer purchases that Mortgage Loan from the Trust
Fund as described below. Upon the agreement of the Servicer to modify a Mortgage
Loan in accordance with the preceding sentence, the Servicer shall purchase that
Mortgage Loan and all interest of the Trustee in that Mortgage Loan shall
automatically be deemed transferred and assigned to the Servicer and all
benefits and burdens of ownership thereof, including the right to accrued
interest thereon from the date of purchase and the risk of default thereon,
shall pass to the Servicer. The Servicer shall promptly deliver to the Trustee a
certification of a Servicing Officer to the effect that all requirements of this
paragraph have been satisfied with respect to a Mortgage Loan to be repurchased
pursuant to this paragraph.

         The Servicer shall deposit the Purchase Price for any Mortgage Loan
repurchased pursuant to Section 3.12 in the Certificate Account pursuant to
Section 3.06 within one Business Day after the purchase of the Mortgage Loan.
Upon receipt by the Trustee of written notification of any such deposit signed
by a Servicing Officer, the Trustee shall release to the Servicer the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as shall be necessary to vest in the
Servicer any Mortgage Loan previously transferred and assigned pursuant hereto.
The Servicer covenants and agrees to indemnify the Trust Fund against any
liability for any "prohibited transaction" taxes and any related interest,
additions, and penalties imposed on the Trust Fund established hereunder as a
result of any modification of a Mortgage Loan effected pursuant to this Section,
or any purchase of a Mortgage Loan by the Servicer in connection with a
modification (but such obligation shall not prevent the Servicer or any other
appropriate Person from contesting any such tax in appropriate proceedings and
shall not prevent the Servicer from withholding payment of such tax, if
permitted by law, pending the outcome of such proceedings). The Servicer shall
have no right of reimbursement for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest, and
penalties, together with interest thereon, is refunded to the Trust Fund.

         Section 3.13 Trustee to Cooperate; Release of Mortgage Files.

         Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will immediately notify the Trustee by
delivering a Request for Release substantially in the form of Exhibit N. Upon
receipt of the request, the Trustee shall promptly release the related Mortgage
File to the Servicer, and the Trustee shall at the Servicer's direction execute
and deliver to the 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 the Servicer, together with the Mortgage
Note with written evidence of cancellation thereon. The Servicer is authorized
to cause the removal from the registration on the MERS System of such Mortgage
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
partial or full release. Expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the related
Mortgagor.

         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, upon delivery to the Trustee

                                       59
<PAGE>

of a Request for Release in the form of Exhibit M signed by a Servicing Officer,
release the Mortgage File to the Servicer or its designee. Subject to the
further limitations set forth below, the Servicer shall cause the Mortgage File
or documents so released to be returned to the Trustee when the need therefor by
the Servicer no longer exists, unless the Mortgage Loan is liquidated and the
proceeds thereof are deposited in the Certificate Account, in which case the
Servicer shall deliver to the Trustee a Request for Release in the form of
Exhibit N, signed by a Servicing Officer.

         If the Servicer at any time seeks to initiate a foreclosure proceeding
in respect of any Mortgaged Property as authorized by this Agreement, the
Servicer shall deliver to the Trustee, for signature, as appropriate, any court
pleadings, requests for trustee's sale, or other documents 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 3.14 Documents, Records and Funds in Possession of the Servicer
to be Held for the Trustee.

         The Servicer shall account fully to the Trustee for any funds it
receives or otherwise collects 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, the Servicer in respect of any Mortgage Loans, whether
from the collection of principal and interest payments or from Liquidation
Proceeds, including any funds on deposit in the Certificate Account, shall be
held by the 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. The Servicer also agrees that it shall not create,
incur or subject any Mortgage File or any funds that are deposited in the
Certificate Account, Distribution Account, or any 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, security interest, judgment,
levy, writ of attachment, or other 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 the
Servicer shall be entitled to set off against and deduct from any such funds any
amounts that are properly due and payable to the Servicer under this Agreement.

         Section 3.15 Servicing Compensation.

         The Servicer may retain or withdraw from the Certificate Account the
Servicing Fee for each Mortgage Loan for the related Distribution Date. If the
Servicer directly services a Mortgage Loan, the Servicer may retain the
Servicing Fee for its own account as compensation for performing services.
Notwithstanding the foregoing, the Servicing Fee payable to the Servicer shall
be reduced by the lesser of the aggregate of the Prepayment Interest Shortfalls
with respect to the Distribution Date and the aggregate Compensating Interest
for the Distribution Date.

         Additional servicing compensation in the form of Excess Proceeds,
Prepayment Interest Excess, assumption fees, late payment charges and all income
net of any losses realized from Permitted Investments shall be retained by the
Servicer to the extent not required to be deposited in the Certificate Account
pursuant to Section 3.06. The Servicer shall be required to pay all expenses
incurred by it in connection with its servicing activities hereunder (including
the payment of any premiums for hazard insurance, and any Primary Insurance
Policy and maintenance of the other forms of insurance coverage required by this
Agreement) and shall not be entitled to reimbursement therefor except as
specifically provided in this Agreement.

                                       60
<PAGE>

         Section 3.16 Access to Certain Documentation.

         The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of Certificates and Certificate
Owners and the examiners and supervisory agents of the OTS, the FDIC, and such
other authorities, access to the documentation regarding the Mortgage Loans
required by applicable regulations of the OTS and the FDIC. Access shall be
afforded without charge, but only upon reasonable prior written request and
during normal business hours at the offices designated by the Servicer. Nothing
in this Section 3.16 shall limit the obligation of the Servicer to observe any
applicable law prohibiting disclosure of information regarding the Mortgagors
and the failure of the Servicer to provide access as provided in this Section
3.16 as a result of such obligation shall not constitute a breach of this
Section 3.16.

         Section 3.17 Annual Statement as to Compliance.

         (a) By March 1 of each year, commencing with 2008, the Servicer shall
deliver to the Trustee via electronic mail (DBSEC.Notifications@db.com) and the
Depositor an Officer's Certificate signed by two Servicing Officers stating, as
to each signer thereof, that (i) a review of the activities of the Servicer
during the preceding calendar year (or applicable portion thereof) and of the
performance of the Servicer under this Agreement has been made under such
officer's supervision, and (ii) to the best of such officer's knowledge, based
on the review, the Servicer has fulfilled all its obligations under this
Agreement, in all material respects throughout the year (or applicable portion
thereof), or, if there has been a failure to fulfill any obligation in any
material respect, specifying each failure known to the officer and the nature
and status thereof.

         (b) [Reserved].

         (c) Copies of such statement shall be provided by the Trustee to any
Certificateholder or Certificate Owner upon request at the Servicer's expense,
provided such statement is delivered by the Servicer to the Trustee.

         Section 3.18 Errors and Omissions Insurance; Fidelity Bonds.

         The Servicer shall obtain and maintain in force (a) policies of
insurance covering errors and omissions in the performance of its obligations as
Servicer hereunder and (b) a fidelity bond covering its officers, employees, and
agents. Each policy and bond shall, together, comply with the requirements from
time to time of FNMA or FHLMC for persons performing servicing for mortgage
loans purchased by FNMA or FHLMC. If any policy or bond ceases to be in effect,
the Servicer shall obtain a comparable replacement policy or bond from an
insurer or issuer meeting the above requirements as of the date of the
replacement.

         Section 3.19 Notification of Adjustments.

         On each Adjustment Date, the Servicer shall make interest rate
adjustments for each Mortgage Loan in compliance with the requirements of the
related Mortgage and Mortgage Note and applicable regulations. The Servicer
shall execute and deliver the notices required by each Mortgage and Mortgage
Note and applicable regulations regarding interest rate adjustments. The
Servicer also shall provide timely notification to the Trustee of all applicable
data and information regarding such interest rate adjustments and the Servicer's
methods of implementing such interest rate adjustments. Upon the discovery by
the Servicer or the Trustee that the Servicer has failed to adjust or has
incorrectly adjusted a Mortgage Rate or a monthly payment pursuant to the terms
of the related Mortgage Note and Mortgage, the Servicer shall immediately
deposit in the Certificate Account from its own funds the amount of any

                                       61
<PAGE>

loss caused thereby without reimbursement therefor; provided, however, the
Servicer shall not be liable with respect to any interest rate adjustments made
by any servicer prior to the Servicer.

         Section 3.20 Prepayment Charges.

         The Servicer will not waive any part of any Prepayment Charge unless
the waiver relates to a default or a reasonably foreseeable default, the
Prepayment Charge would cause an undue hardship to the related borrower, the
Mortgaged Property is sold by the Mortgagor, the collection of any Prepayment
Charge would violate any relevant law or regulation or the waiving of the
Prepayment Charge would otherwise benefit the Trust Fund and it is expected that
the waiver would maximize recovery of total proceeds taking into account the
value of the Prepayment Charge and related Mortgage Loan and doing so is
standard and customary in servicing similar Mortgage Loans (including any waiver
of a Prepayment Charge in connection with a refinancing of a Mortgage Loan that
is related to a default or a reasonably foreseeable default). The Servicer will
not waive a Prepayment Charge in connection with a refinancing of a Mortgage
Loan that is not related to a default or a reasonably foreseeable default.

         If a Prepayment Charge is waived other than as permitted by the prior
paragraph, then the Servicer is required to pay the amount of such waived
Prepayment Charge, for the benefit of the Holders of the related Class of Class
P Certificates, by depositing such amount into the Distribution Account from its
own funds, without any right of reimbursement therefor, together with and at the
time that the amount prepaid on the related Mortgage Loan is required to be
deposited into the Distribution Account.

                   DISTRIBUTIONS AND ADVANCES BY THE SERVICER

         Section 4.01 Advances.

         (a) The Servicer shall determine on or before each Servicer Advance
Date whether it is required to make an Advance pursuant to the definition
thereof. If the Servicer determines it is required to make an Advance, it shall,
on or before the Servicer Advance Date, either (i) deposit into the Certificate
Account an amount equal to the Advance or (ii) make an appropriate entry in its
records relating to the Certificate Account that any Amount Held for Future
Distribution has been used by the Servicer in discharge of its obligation to
make any such Advance. Any funds so applied shall be replaced by the Servicer by
deposit in the Certificate Account no later than the close of business on the
next Servicer Advance Date. The Servicer shall be entitled to be reimbursed from
the Certificate Account for all Advances of its own funds made pursuant to this
Section 4.01 as provided in Section 3.09. The obligation to make Advances with
respect to any Mortgage Loan shall continue if such Mortgage Loan has been
foreclosed or otherwise terminated and the Mortgaged Property has not been
liquidated. The Servicer shall inform the Trustee of the amount of the Advance
to be made on each Servicer Advance Date no later than the second Business Day
before the related Distribution Date.

         (b) If the Servicer determines that it will be unable to comply with
its obligation to make the Advances as and when described in the second sentence
of Section 4.01(a), it shall use its best efforts to give written notice thereof
to the Trustee (each such notice an "Advance Notice"; and such notice may be
given by telecopy), not later than 3:00 P.M., New York time, on the Business Day
immediately preceding the related Servicer Advance Date, specifying the amount
that it will be unable to deposit (each such amount an "Advance Deficiency") and
certifying that such Advance Deficiency constitutes an Advance hereunder and is
not a Nonrecoverable Advance. If the Trustee receives a Trustee Advance Notice
on or before 3:00 P.M., New York time on a Servicer Advance Date, the Trustee is
entitled to immediately terminate the Servicer under Section 7.01, and shall,
not later than 3:00 P.M., New York time, on the related Distribution Date,
deposit in the Distribution Account an amount equal to the Advance Deficiency
identified in such Trustee Advance Notice unless it is prohibited from so doing
by applicable law. Notwithstanding the foregoing, the Trustee shall not be
required to make such deposit if the Trustee shall have received written
notification from the Servicer that the Servicer has deposited or caused to be
deposited in the Certificate Account an amount equal to such Advance Deficiency
by 3:00 P.M. New York time on the related Distribution Date. If the Trustee has
not terminated the Servicer, the Servicer shall reimburse the Trustee for the
amount of any Advance (including interest at the Prime Rate on the day of such
reimbursement published in The Wall Street Journal) on such amount, made by the
Trustee pursuant to this Section 4.01(b) not later than the second day following
the related Servicer Advance Date. In the event that the Servicer does not
reimburse the Trustee in accordance with the requirements of the preceding
sentence, the Trustee shall immediately (a) terminate all of the rights and
obligations of the Servicer under this Agreement in accordance with Section 7.01
and (b) subject to the limitations set forth in Section 3.05, assume all of the
rights and obligations of the Servicer hereunder.

         (c) The Servicer shall, not later than the close of business on the
Business Day immediately preceding each Servicer Advance Date, deliver to the
Trustee a report (in form and substance reasonably satisfactory to the Trustee)
that indicates (i) the Mortgage Loans with respect to which the Servicer has
determined that the related Scheduled Payments should be advanced and (ii) the
amount of the related Scheduled Payments. The Servicer shall deliver to the
Trustee on the related Servicer Advance Date an Officer's Certificate of a
Servicing Officer indicating the amount of any proposed Advance determined by
the Servicer to be a Nonrecoverable Advance.
