         the business in which it is currently engaged. The Servicer is duly
         qualified to do business as a foreign corporation and is in good
         standing in each jurisdiction in which the character of the business
         transacted by it or properties owned or leased by it requires such

                           (ii) The Servicer has the power and authority to
         make, execute, deliver and perform this Servicing Agreement and all of
         the transactions contemplated under this Servicing Agreement, and has
         taken all necessary corporate action to authorize the execution,
         delivery and performance of this Servicing Agreement. When executed and
         delivered, this Servicing Agreement will constitute the legal, valid
         and binding obligation of the Servicer enforceable in accordance with
         its terms, except as enforcement of such terms may be limited by
         bankruptcy, insolvency or similar laws affecting the enforcement of
         creditors' rights generally and by the availability of equitable
         remedies;

                           (iii) The Servicer is not required to obtain the
         consent of any other Person or any consent, license, approval or
         authorization from, or registration or declaration with, any
         governmental authority, bureau or agency in connection with the
         execution, delivery, performance, validity or enforceability of this
         Servicing Agreement, except for such consent, license, approval or
         authorization, or registration or declaration, as shall have been
         obtained or filed, as the case may be;

                           (iv) The execution and delivery of this Servicing
         Agreement and the performance of the transactions contemplated hereby
         by the Servicer will not violate any provision of any existing law or
         regulation or any order or decree of any court applicable to the
         Servicer or any provision of the Certificate of Incorporation or Bylaws
         of the Servicer, or constitute a material breach of any mortgage,
         indenture, contract or other agreement to which the Servicer is a party
         or by which the Servicer may be bound; and

                           (v) No litigation or administrative proceeding of or
         before any court, tribunal or governmental body is currently pending,
         or to the knowledge of the Servicer threatened, against the Servicer or
         any of its properties or with respect to this Servicing Agreement or
         the Notes or the Certificates which in the opinion of the Servicer has
         a


                                       -3-

<PAGE>



         reasonable likelihood of resulting in a material adverse effect on the
         transactions contemplated by this Servicing Agreement.

         The foregoing representations and warranties shall survive any
termination of the Servicer hereunder.

         Section 2.02 REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
hereby represents and warrants to the Servicer for the benefit of the Indenture
Trustee, as pledgee of the Mortgage Collateral, and the Securityholders, as of
the Cut-Off Date, the Closing Date and any Deposit Date, that:

                           (i) The Company is a corporation in good standing
         under the laws of the State of Delaware;

                           (ii) The Company has full power, authority and legal
         right to execute and deliver this Servicing Agreement and to perform
         its obligations under this Servicing Agreement, and has taken all
         necessary action to authorize the execution, delivery and performance
         by it of this Servicing Agreement; and

                           (iii) The execution and delivery by the Company of
         this Servicing Agreement and the performance by the Company of its
         obligations under this Servicing Agreement will not violate any
         provision of any law or regulation governing the Company or any order,
         writ, judgment or decree of any court, arbitrator or governmental
         authority or agency applicable to the Company or any of its assets.
         Such execution, delivery, authentication and performance will not
         require the authorization, consent or approval of, the giving of notice
         to, the filing or registration with, or the taking of any other action
         with respect to, any governmental authority or agency regulating the
         activities of limited liability companies. Such execution, delivery,
         authentication and performance will not conflict with, or result in a
         breach or violation of, any mortgage, deed of trust, lease or other
         agreement or instrument to which the Company is bound.

         Section 2.03 ENFORCEMENT OF REPRESENTATIONS AND WARRANTIES. The
Servicer, on behalf of and subject to the direction of the Indenture Trustee, as
pledgee of the Mortgage Collateral, or the Credit Enhancer, shall enforce the
representations and warranties of the Seller pursuant to the Mortgage Loan
Purchase Agreement. Upon the discovery by the Seller, the Servicer, the
Indenture Trustee, the Credit Enhancer, the Company or any Custodian of a breach
of any of the representations and warranties made in the Mortgage Loan Purchase
Agreement, in respect of any Mortgage Loan which materially and adversely
affects the interests of the Securityholders or the Credit Enhancer, the party
discovering such breach shall give prompt written notice to the other parties
(any Custodian being so obligated under a Custodial Agreement). The Servicer
shall promptly notify the Seller of such breach and request that, pursuant to
the terms of the Mortgage Loan Purchase Agreement, the Seller either (i) cure
such breach in all material respects within 45 days (with respect to a breach of
the representations and warranties contained in Section 3.1(a) of the Mortgage
Loan Purchase Agreement) or 90 days (with respect to a breach of the
representations and warranties contained in Section 3.1(b) of the Mortgage Loan
Purchase Agreement) from the date the Seller was notified of such breach or (ii)
purchase such Mortgage Loan from the Company at the


                                       -4-

<PAGE>



price and in the manner set forth in Section 3.1(b) of the Mortgage Loan
Purchase Agreement; PROVIDED that the Seller shall, subject to the conditions
set forth in the Mortgage Loan Purchase Agreement, have the option to substitute
an Eligible Substitute Mortgage Loan or Loans for such Mortgage Loan. In the
event that the Seller elects to substitute one or more Eligible Substitute
Mortgage Loans pursuant to Section 3.1(b) of the Mortgage Loan Purchase
Agreement, the Seller shall deliver to the Company with respect to such Eligible
Substitute Mortgage Loans, the original Mortgage Note, the Mortgage, and such
other documents and agreements as are required by the Mortgage Loan Purchase
Agreement. No substitution will be made in any calendar month after the
Determination Date for such month. Payments due with respect to Eligible
Substitute Mortgage Loans in the month of substitution shall not be transferred
to the Company and will be retained by the Servicer and remitted by the Servicer
to the Seller on the next succeeding Payment Date provided a payment has been
received by the Company for such month in respect of the Mortgage Loan to be
removed. The Servicer shall amend or cause to be amended the Mortgage Loan
Schedule to reflect the removal of such Mortgage Loan and the substitution of
the Eligible Substitute Mortgage Loans and the Servicer shall promptly deliver
the amended Mortgage Loan Schedule to the Owner Trustee and Indenture Trustee.

         It is understood and agreed that the obligation of the Seller to cure
such breach or purchase or substitute for such Mortgage Loan as to which such a
breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to the Company and the Indenture Trustee, as
pledgee of the Mortgage Collateral, against the Seller. In connection with the
purchase of or substitution for any such Mortgage Loan by the Seller, the
Company shall assign to the Seller all of the right, title and interest in
respect of the Mortgage Loan Purchase Agreement applicable to such Mortgage
Loan. Upon receipt of the Repurchase Price, or upon completion of such
substitution, the applicable Custodian shall deliver the Mortgage Files to the
Servicer, together with all relevant endorsements and assignments.

                                   ARTICLE III

                 Administration and Servicing of Mortgage Loans

         Section 3.01 THE SERVICER. (a) The Servicer shall service and
administer the Mortgage Loans in the same manner as would prudent institutional
mortgage lenders servicing comparable mortgage loans for their own account in
the jurisdictions where the related Mortgaged Properties are located and in a
manner consistent with the terms of this Servicing Agreement and which shall be
normal and usual in its general mortgage servicing activities and shall have
full power and authority, acting alone or through a subservicer, to do any and
all things in connection with such servicing and administration which it may
deem necessary or desirable, it being understood, how ever, that the Servicer
shall at all times remain responsible to the Company, the Indenture Trustee, as
pledgee of the Mortgage Collateral, and the Securityholders for the performance
of its duties and obligations hereunder in accordance with the terms hereof and
the servicing standard set forth above. Without limiting the generality of the
foregoing, the Servicer shall continue, and is hereby authorized and empowered
by the Company and the Indenture Trustee, as pledgee of the Mortgage Collateral,
to execute and deliver, on behalf of itself, the Company, the Securityholders
and the Indenture Trustee or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge and all
other comparable instruments with respect to the Mortgage Loans and with respect
to the Mortgaged Properties. The Company, the Indenture Trustee and the
Custodian, as applicable, shall furnish the Servicer with any powers of attorney
and other documents necessary or appropriate to enable the Servicer to carry out
its servicing and administrative duties hereunder. On the Closing Date, the
Company shall deliver to the Servicer a power of attorney substantially in the
form of Exhibit B hereto.

         If the Mortgage relating to a Mortgage Loan did not have a lien senior
on the related Mortgaged Property as of the Cut-Off Date, then the Servicer, in
such capacity, may not consent to the placing of a lien senior to that of the
Mortgage on the related Mortgaged Property. If the Mortgage relating to a
Mortgage Loan had a lien senior to the Mortgage Loan on the related Mort gaged
Property as of the Cut-Off Date, then the Servicer, in such capacity, may
consent to the refinancing of such senior lien; PROVIDED that (i) the resulting
Combined Loan-to-Value Ratio of such Mortgage Loan is no higher than the
Combined Loan-to-Value Ratio prior to such refinancing and (ii) the interest
rate for the loan evidencing the refinanced senior lien on the date of such
refinancing is no higher than the interest rate on the loan evidencing the
existing senior lien immediately prior to the date of such refinancing.

         The relationship of the Servicer (and of any successor to the Servicer
as servicer under this Servicing Agreement) to the Company under this Servicing
Agreement is intended by the parties to be that of an independent contractor and
not that of a joint venturer, partner or agent.

         (b) The Servicer has entered into Initial Subservicing Agreements with
the Initial Subservicers for the servicing and administration of the Mortgage
Loans and may enter into additional Sub servicing Agreements with Subservicers
for the servicing and administration of certain of the Mortgage Loans.
References in this Servicing Agreement to actions taken or to be taken by the
Servicer in servicing the Mortgage Loans include actions taken or to be taken by
a


                                       -6-

<PAGE>



Subservicer on behalf of the Servicer and any amount received by such
Subservicer in respect of a Mortgage Loan shall be deemed to have been received
by the Servicer whether or not actually received by the Servicer. Each
Subservicing Agreement will be upon such terms and conditions as are not
inconsistent with this Servicing Agreement and as the Servicer and the
Subservicer have agreed. With the approval of the Servicer, a Subservicer may
delegate its servicing obligations to third-party servicers, but such
Subservicers will remain obligated under the related Subservicing Agreements.
The Servicer and the Subservicer may enter into amendments to the related
Subservicing Agreements; PROVIDED, HOWEVER, that any such amendments shall be
consistent with and not violate the provisions of this Servicing Agreement. The
Servicer shall be entitled to terminate any Subservicing Agreement in accordance
with the terms and conditions thereof and without any limitation by virtue of
this Servicing Agreement; PROVIDED, HOWEVER, that in the event of termination of
any Subservicing Agreement by the Servicer or the Subservicer, the Servicer
shall either act as servicer of the related Mortgage Loan or enter into a
Subservicing Agreement with a successor Subservicer which will be bound by the
terms of the related Subservicing Agreement. The Servicer shall be entitled to
enter into any agreement with a Subservicer for indemnification of the Servicer
and nothing contained in this Servicing Agreement shall be deemed to limit or
modify such indemnification.

         In the event that the rights, duties and obligations of the Servicer
are terminated hereunder, any successor to the Servicer in its sole discretion
may, to the extent permitted by applicable law, terminate the existing
Subservicing Agreement with any Subservicer in accordance with the terms of the
applicable Subservicing Agreement or assume the terminated Servicer's rights and
obligations under such subservicing arrangements which termination or assumption
will not violate the terms of such arrangements.

         As part of its servicing activities hereunder, the Servicer, for the
benefit of the Company, shall use reasonable efforts to enforce the obligations
of each Subservicer under the related Subservicing Agreement, to the extent that
the non-performance of any such obligation would have material and adverse
effect on a Mortgage Loan. Such enforcement, including, without limitation, the
legal prosecution of claims, termination of Subservicing Agreements and the
pursuit of other appropriate remedies, shall be in such form and carried out to
such an extent and at such time as the Servicer, in its good faith business
judgment, would require were it the owner of the related Mortgage Loans. The
Servicer shall pay the costs of such enforcement at its own expense, and shall
be reimbursed therefor only (i) from a general recovery resulting from such
enforcement to the extent, if any, that such recovery exceeds all amounts due in
respect of the related Mortgage Loan or (ii) from a specific recovery of costs,
expenses or attorneys fees against the party against whom such enforcement is
directed.

         Section 3.02 COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS. (a) The
Servicer shall make reasonable efforts to collect all payments called for under
the terms and provisions of the Mortgage Loans, and shall, to the extent such
procedures shall be consistent with this Servicing Agreement, follow such
collection procedures as shall be normal and usual in its general mortgage
servicing activities. Consistent with the foregoing, and without limiting the
generality of the foregoing, the Servicer may in its discretion (i) waive any
late payment charge, penalty interest or other fees which may be collected in
the ordinary course of servicing such Mortgage Loan and (ii) arrange with a
Mortgagor a schedule for the payment of principal and interest due and unpaid;
PROVIDED such


                                       -7-

<PAGE>



arrangement is consistent with the Servicer's policies with respect to home
equity mortgage loans; PROVIDED, FURTHER, that notwithstanding such arrangement
such Mortgage Loans will be included in the information regarding delinquent
Mortgage Loans set forth in the Servicing Certificate. The Servicer may also
extend the Due Date for payment due on a Mortgage Loan, PROVIDED, HOWEVER, that
the Servicer shall first determine that any such waiver or extension will not
adversely affect the lien of the related Mortgage. Consistent with the terms of
this Servicing Agreement, the Servicer may also waive, modify or vary any term
of any Mortgage Loan or consent to the postponement of strict compliance with
any such term or in any manner grant indulgence to any Mortgagor if in the
Servicer's determination such waiver, modification, postponement or indulgence
is not materially adverse to the interests of the Securityholders or the Credit
Enhancer, PROVIDED, HOWEVER, that the Servicer may not modify or permit any
Subservicer to modify any Mortgage Loan (including without limitation any
modification that would change the Mortgage Rate, forgive the payment of any
principal or interest (unless in connection with the liquidation of the related
Mortgage Loan) or extend the final maturity date of such Mortgage Loan) unless
such Mortgage Loan is in default or, in the judgment of the Servicer, such
default is reasonably foreseeable.

         (b) The Servicer shall establish an account (the "Collection Account")
in which the Servicer shall deposit or cause to be deposited any amounts
representing payments on and any collections in respect of the Mortgage Loans
received by it subsequent to the Cut-off Date as to any Initial Loan or the
related Deposit Date as to any Additional Loan (other than in respect of the
payments referred to in the following paragraph) within __ Business Day[s]
following receipt thereof (or otherwise on or prior to the Closing Date),
including the following payments and collections received or made by it (without
duplication):

                           (i) all payments of principal of or interest on the
         Mortgage Loans received by the Servicer from the respective
         Subservicer, net of any portion of the interest thereof retained by the
         Subservicer as Subservicing Fees;

                           (ii) the aggregate Repurchase Price of the Mortgage
         Loans purchased by the Servicer pursuant to Section 3.15;

                           (iii) Net Liquidation Proceeds net of any related
         Foreclosure Profit;

                           (iv) all proceeds of any Mortgage Loans repurchased
         by the Seller pursuant to the Mortgage Loan Purchase Agreement, and all
         Substitution Adjustment Amounts required to be deposited in connection
         with the substitution of an Eligible Substitute Mortgage Loan pursuant
         to the Mortgage Loan Purchase Agreement;

                           (v) insurance proceeds, other than Net Liquidation
         Proceeds, resulting from any insurance policy maintained on a Mortgaged
         Property; and

                           (vi) amounts required to be paid by the Servicer
         pursuant to Section 8.08.

PROVIDED, HOWEVER, that with respect to each Collection Period, the Servicer
shall be permitted to retain from payments in respect of interest on the
Mortgage Loans, the Servicing Fee for such Collection Period. The foregoing
requirements respecting deposits to the Collection Account are


                                       -8-

<PAGE>



exclusive, it being understood that, without limiting the generality of the
foregoing, the Servicer need not deposit in the Collection Account amounts
representing Foreclosure Profits, fees (including annual fees) or late charge
penalties, payable by Mortgagors, or amounts received by the Servicer for the
accounts of Mortgagors for application towards the payment of taxes, insurance
premiums, assessments and similar items. In the event any amount not required to
be deposited in the Collection Account is so deposited, the Servicer may at any
time withdraw such amount from the Collection Account, any provision herein to
the contrary notwithstanding. The Collection Account may contain funds that
belong to one or more trust funds created for the notes or certificates of other
series and may contain other funds respecting payments on mortgage loans
belonging to the Servicer or serviced or serviced by it on behalf of others.
Notwithstanding such commingling of funds, the Servicer shall keep records that
accurately reflect the funds on deposit in the Collection Account that have been
identified by it as being attributable to the Mortgage Loans and shall hold all
collections in the Collection Account to the extent they represent collections
on the Mortgage Loans for the benefit of the Company, the Indenture Trustee, the
Securityholders and the Credit Enhancer, as their interests may appear. The
Servicer shall remit all Foreclosure Profits to itself as additional servicing
compensation.

         The Servicer may cause the institution maintaining the Collection
Account to invest any funds in the Collection Account in Eligible Investments
(including obligations of the Servicer or any of its Affiliates, if such
obligations otherwise qualify as Eligible Investments), which shall mature not
later than the Business Day next preceding the Payment Date and shall not be
sold or disposed of prior to its maturity. Except as provided above, all income
and gain realized from any such investment shall be for the benefit of the
Servicer and shall be subject to its withdrawal or order from time to time. The
amount of any losses incurred in respect of the principal amount of any such
investments shall be deposited in the Collection Account by the Servicer out of
its own funds immediately as realized.

         (c) The Servicer will require each Subservicer to hold all funds
constituting collections on the Mortgage Loans, pending remittance thereof to
the Servicer, in one or more accounts meeting the requirements of an Eligible
Account, and invested in Eligible Investments, unless, all such collections are
remitted on a daily basis to the Servicer for deposit into the Collection
Account.

         Section 3.03 WITHDRAWALS FROM THE COLLECTION ACCOUNT. The Servicer
shall, from time to time as provided herein, make withdrawals from the
Collection Account of amounts on deposit therein pursuant to Section 3.02 that
are attributable to the Mortgage Loans for the following purposes:

                           (i) to deposit in the Distribution Account, on the
         Business Day prior to each Payment Date, an amount equal to the
         Security Collections required to be distributed on such Payment Date;

                           (ii) to the extent deposited to the Collection
         Account, to reimburse itself or the related Subservicer for previously
         unreimbursed expenses incurred in maintaining individual insurance
         policies pursuant to Section 3.04, or Liquidation Expenses, paid
         pursuant to Section 3.07 or otherwise reimbursable pursuant to the
         terms of this Servicing Agreement (to the extent not payable pursuant
         to Section 3.09), such withdrawal right being


                                       -9-

<PAGE>



         limited to amounts received on particular Mortgage Loans (other than
         any Repurchase Price in respect thereof) which represent late
         recoveries of the payments for which such advances were made, or from
         related Liquidation Proceeds or the proceeds of the purchase of such
         Mortgage Loan;

                           (iii) to pay to itself out of each payment received
         on account of interest on a Mortgage Loan as contemplated by Section
         3.09, an amount equal to the related Servicing Fee (to the extent not
         retained pursuant to Section 3.02), and to pay to any Subservicer any
         Subservicing Fees not previously withheld by the Subservicer;

                           (iv) to the extent deposited in the Collection
         Account to pay to itself as additional servicing compensation any
         interest or investment income earned on funds deposited in the
         Collection Account and Payment Account that it is entitled to withdraw
         pursuant to Sections 3.02(b) and 5.01;

                           (v) to the extent deposited in the Collection
         Account, to pay to itself as additional servicing compensation any
         Foreclosure Profits;

                           (vi) to pay to itself or the Seller, with respect to
         any Mortgage Loan or property acquired in respect thereof that has been
         purchased or otherwise transferred to the Seller, the Servicer or other
         entity, all amounts received thereon and not required to be distributed
         to Securityholders as of the date on which the related Purchase Price
         or Repurchase Price is determined;

                           (vii) to withdraw any other amount deposited in the
         Collection Account that was not required to be deposited therein
         pursuant to Section 3.02;

                           (viii) to pay to the Seller the amount, if any,
         deposited in the Collection Account by the Indenture Trustee upon
         release thereof from the Funding Account representing payments for
         Additional Loans; and

                           (ix) after the occurrence of an Amortization Event,
         to pay to the Seller, the Excluded Amount.

Since, in connection with withdrawals pursuant to clauses (iii), (iv), (vi) and
(vii), the Servicer's entitlement thereto is limited to collections or other
recoveries on the related Mortgage Loan, the Servicer shall keep and maintain
separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose
of justifying any withdrawal from the Collection Account pursuant to such
clauses. Notwithstanding any other provision of this Servicing Agreement, the
Servicer shall be entitled to reimburse itself for any previously unreimbursed
expenses incurred pursuant to Section 3.07 or otherwise reimbursable pursuant to
the terms of this Servicing Agreement that the Servicer determines to be
otherwise nonrecoverable (except with respect to any Mortgage Loan as to which
the Repurchase Price has been paid), by withdrawal from the Collection Account
of amounts on deposit therein attributable to the Mortgage Loans on any Business
Day prior to the Payment Date succeeding the date of such determination.

         Section 3.04 MAINTENANCE OF HAZARD INSURANCE; PROPERTY PROTECTION
EXPENSES. The Servicer shall cause to be maintained for each Mortgage Loan
hazard insurance naming the Servicer or related Subservicer as loss payee
thereunder providing extended coverage in an amount which is at least equal to
the lesser of (i) the maximum insurable value of the improvements securing such
Mortgage Loan from time to time or (ii) the combined principal balance owing on
such Mortgage Loan and any mortgage loan senior to such Mortgage Loan from time
to time. The Servicer shall also cause to be maintained on property acquired
upon foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan, fire
insurance with extended coverage in an amount which is at least equal to the
amount necessary to avoid the application of any co-insurance clause contained
in the related hazard insurance policy. Amounts collected by the Servicer under
any such policies (other than amounts to be applied to the restoration or repair
of the related Mortgaged Property or property thus acquired or amounts released
to the Mortgagor in accordance with the Servicer's normal servicing procedures)
shall be deposited in the Collection Account to the extent called for by Section
3.02. In cases in which any Mortgaged Property is located at any time during the
life of a Mortgage Loan in a federally designated flood area, the hazard
insurance to be maintained for the related Mortgage Loan shall include flood
insurance (to the extent available). All such flood insurance shall be in
amounts equal to the lesser of (i) the amount required to compensate for any
loss or damage to the Mortgaged Property on a replacement cost basis and (ii)
the maximum amount of such insurance available for the related Mortgaged
Property under the national flood insurance program (assuming that the area in
which such Mortgaged Property is located is participating in such program). The
Servicer shall be under no obligation to require that any Mortgagor maintain
earthquake or other additional insurance and shall be under no obligation itself
to maintain any such additional insurance on property acquired in respect of a
Mortgage Loan, other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance. If
the Servicer shall obtain and maintain a blanket policy consistent with its
general mortgage servicing activities insuring against hazard losses on all of
the Mortgage Loans, it shall conclusively be deemed to have satisfied its
obligations as set forth in the first sentence of this Section 3.04, it being
understood and agreed that such policy may contain a deductible clause, in which
case the Servicer shall, in the event that there shall not have been maintained
on the related Mortgaged Property a policy complying with the first sentence of
this Section 3.04 and there shall have been a loss which would have been covered
by such policy, deposit in the Collection Account the amount not otherwise
payable under the blanket policy because of such deductible clause. Any such
deposit by the Servicer shall be made on the last Business Day of the Collection
Period in the month in which payments under any such policy would have been
deposited in the Collection Account. In connection with its activities as
administrator and servicer of the Mortgage Loans, the Servicer agrees to
present, on behalf of itself, the Company, the Issuer, the Indenture Trustee and
the Securityholders, claims under any such blanket policy.

         Section 3.05 MODIFICATION AGREEMENTS. The Servicer or the related
Subservicer, as the case may be, shall be entitled to (A) execute assumption
agreements, substitution agreements, and instruments of satisfaction or
cancellation or of partial or full release or discharge, or any other document
contemplated by this Servicing Agreement and other comparable instruments with
respect to the Mortgage Loans and with respect to the Mortgaged Properties
subject to the Mortgages (and the Company shall promptly execute any such
documents on request of the Servicer) and (B) approve the granting of an
easement thereon in favor of another Person, any alteration or demolition of the
related Mortgaged Property or other similar matters, if it has determined,
exercising its good


                                      -11-

<PAGE>



faith business judgment in the same manner as it would if it were the owner of
the related Mortgage Loan, that the security for, and the timely and full
collectability of, such Mortgage Loan would not be adversely affected thereby. A
partial release pursuant to this Section 3.05 shall be permitted only if the
Combined Loan-to-Value Ratio for such Mortgage Loan after such partial release
does not exceed the Combined Loan-to-Value Ratio for such Mortgage Loan as of
the Cut-Off Date. Any fee collected by the Servicer or the related Subservicer
for processing such request will be retained by the Servicer or such Subservicer
as additional servicing compensation.

         Section 3.06 TRUST ESTATE; RELATED DOCUMENTS. (a) When required by the
provisions of this Servicing Agreement, the Company shall execute instruments to
release property from the terms of this Servicing Agreement, or convey the
Company's interest in the same, in a manner and under circumstances which are
not inconsistent with the provisions of this Servicing Agreement. No party
relying upon an instrument executed by the Company as provided in this Article
III shall be bound to ascertain the Company's authority, inquire into the
satisfaction of any conditions precedent or see to the application of any
moneys.

         (b) If from time to time the Servicer shall deliver to the Company or
the related Custodian copies of any written assurance, assumption agreement or
substitution agreement or other similar agreement pursuant to Section 3.05, the
Company or the related Custodian shall check that each of such documents
purports to be an original executed copy (or a copy of the original executed
document if the original executed copy has been submitted for recording and has
not yet been returned) and, if so, shall file such documents, and upon receipt
of the original executed copy from the applicable recording office or receipt of
a copy thereof certified by the applicable recording office shall file such
originals or certified copies with the Related Documents. If any such documents
submitted by the Servicer do not meet the above qualifications, such documents
shall promptly be returned by the Company or the related Custodian to the
Servicer, with a direction to the Servicer to forward the correct documentation.

         (c) Upon Company Request accompanied by an Officers' Certificate of the
Servicer pursuant to Section 3.09 of this Servicing Agreement to the effect that
a Mortgage Loan has been the subject of a final payment or a prepayment in full
and the related Mortgage Loan has been terminated or that substantially all
Liquidation Proceeds which have been determined by the Servicer in its
reasonable judgment to be finally recoverable have been recovered, and upon
deposit to the Collection Account of such final monthly payment, prepayment in
full together with accrued and unpaid interest to the date of such payment with
respect to such Mortgage Loan or, if applicable, Liquidation Proceeds, the
Company shall promptly release the Related Documents to the Servicer, along with
such documents as the Servicer or the Mortgagor may request as contemplated by
the Servicing Agreement to evidence satisfaction and discharge of such Mortgage
Loan. If from time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan, the Servicer requests the Company or the related Custodian
to release the Related Documents and delivers to the Company or the related
Custodian a trust receipt reasonably satisfactory to the Company or the related
Custodian and signed by a Responsible Officer of the Servicer, the Company or
the related Custodian shall release the Related Documents to the Servicer. If
such Mortgage Loans shall be liquidated and the Company or the related Custodian
receives a certificate from the Servicer as provided above, then, upon request
of the Company or the related Custodian shall release the trust receipt to the
Servicer.

         Section 3.07 REALIZATION UPON DEFAULTED MORTGAGE LOANS. With respect to
such of the Mortgage Loans as come into and continue in default, the Servicer
will decide whether to foreclose upon the Mortgaged Properties securing such
Mortgage Loans or write off the unpaid principal balance of the Mortgage Loans
as bad debt; PROVIDED that if the Servicer has actual knowledge that any
Mortgaged Property is affected by hazardous or toxic wastes or substances and
that the acquisition of such Mortgaged Property would not be commercially
reasonable, then the Servicer will not cause the Company to acquire title to
such Mortgaged Property in a foreclosure or similar proceeding. In connection
with such foreclosure or other conversion, the Servicer shall follow such
practices (including, in the case of any default on a related senior mortgage
loan, the advancing of funds to correct such default) and procedures as it shall
deem necessary or advisable and as shall be normal and usual in its general
mortgage servicing activities; PROVIDED that the Servicer shall not be liable in
any respect hereunder if the Servicer is acting in connection with any such
foreclosure or attempted foreclosure which is not completed or other conversion
in a manner that is consistent with the provisions of this Servicing Agreement.
The foregoing is subject to the proviso that the Servicer shall not be required
to expend its own funds in connection with any fore closure or attempted
foreclosure which is not completed or towards the correction of any default on a
related senior mortgage loan or restoration of any property unless it shall
determine that such expenditure will increase Net Liquidation Proceeds. In the
event of a determination by the Servicer that any such expenditure previously
made pursuant to this Section 3.07 will not be reimbursable from Net Liquidation
Proceeds, the Servicer shall be entitled to reimbursement of its funds so
expended pursuant to Section 3.03.

         Notwithstanding any provision of this Servicing Agreement, a Mortgage
Loan may be deemed to be finally liquidated if substantially all amounts
expected by the Servicer to be received in connection with the related defaulted
Mortgage Loan have been received; PROVIDED, HOWEVER, any subsequent collections
with respect to any such Mortgage Loan shall be deposited to the Collection
Account. For purposes of determining the amount of any Liquidation Proceeds or
Insurance Proceeds, or other unscheduled collections, the Servicer may take into
account minimal amounts of additional receipts expected to be received or any
estimated additional liquidation expenses expected to be incurred in connection
with the related defaulted Mortgage Loan.

         In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be issued to the Company and the Indenture Trustee as their interests may
appear, or to their respective nominee on behalf of Securityholders.
Notwithstanding any such acquisition of title and cancellation of the related
Mortgage Loan, such Mortgaged Property shall (except as otherwise expressly
provided herein) be considered to be an outstanding Mortgage Loan held as an
asset of the Company until such time as such property shall be sold. Consistent
with the foregoing for purposes of all calculations hereunder, so long as such
Mortgaged Property shall be considered to be an outstanding Mortgage Loan it
shall be assumed that, notwithstanding that the indebtedness evidenced by the
related Mortgage Note shall have been discharged, such Mortgage Note in effect
at the time of any such acquisition of title before any adjustment thereto by
reason of any bankruptcy or similar proceeding or any moratorium or similar
waiver or grace period will remain in effect.

         Any proceeds from foreclosure proceedings or the purchase or repurchase
of any Mortgage Loan pursuant to the terms of this Servicing Agreement, as well
as any recovery resulting from a


                                      -13-

<PAGE>



collection of Liquidation Proceeds or Insurance Proceeds, will be applied in the
following order of priority: first, to reimburse the Servicer or the related
Subservicer in accordance with Section 3.07; second, to all Servicing Fees
payable therefrom; third, to the extent of accrued and unpaid interest on the
related Mortgage Loan, at the Net Mortgage Rate to the Due Date prior to the
Payment Date on which such amounts are to be deposited in the Payment Account;
fourth, as a recovery of principal on the Mortgage Loan; and fifth, to
Foreclosure Profits.

         Section 3.08 COMPANY AND INDENTURE TRUSTEE TO COOPERATE. On or before
each Payment Date, the Servicer will notify the Indenture Trustee or the
relevant Custodian, with a copy to the Company, of the termination of or the
payment in full and the termination of any Mortgage Loan during the preceding
Collection Period, which notification shall be by a certification in
substantially the form attached hereto as Exhibit C (which certification shall
include a statement to the effect that all amounts received in connection with
such payment which are required to be deposited in the Collection Account
pursuant to Section 3.02 have been so deposited or credited) of a Servicing
Officer. Upon receipt of payment in full, the Servicer is authorized to execute,
pursuant to the authorization contained in Section 3.01, if the assignments of
Mortgage have been recorded as required under the Mortgage Loan Purchase
Agreement, an instrument of satisfaction regarding the related Mortgage, which
instrument of satisfaction shall be recorded by the Servicer if required by
applicable law and be delivered to the Person entitled thereto. It is understood
and agreed that any expenses incurred in connection with such instrument of
satisfaction or transfer shall be reimbursed from amounts deposited in the
Collection Account. From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, the Indenture Trustee or the relevant
Custodian shall, upon request of the Servicer and delivery to the Indenture
Trustee or relevant Custodian, with a copy to the Company, of a Request for
Release, in the form annexed hereto as Exhibit D, signed by a Servicing Officer,
release or cause to be released the related Mortgage File to the Servicer and
the Company and Indenture Trustee shall promptly execute such documents, in the
forms provided by the Servicer, as shall be necessary for the prosecution of any
such proceedings or the taking of other servicing actions. Such trust receipt
shall obligate the Servicer to return the Mortgage File to the Indenture Trustee
or the related Custodian (as specified in such receipt) when the need therefor
by the Servicer no longer exists unless the Mortgage Loan shall be liquidated,
in which case, upon receipt of a certificate of a Servicing Officer similar to
that hereinabove specified, the trust receipt shall be released to the Servicer.

         In order to facilitate the foreclosure of the Mortgage securing any
Mortgage Loan that is in default following recordation of the assignments of
Mortgage in accordance with the provisions of the Mortgage Loan Purchase
Agreement, the Company shall, if so requested in writing by the Servicer,
promptly execute an appropriate assignment in the form provided by the Servicer
to assign such Mortgage Loan for the purpose of collection to the Servicer (any
such assignment shall unambiguously indicate that the assignment is for the
purpose of collection only), and, upon such assignment, such assignee for
collection will thereupon bring all required actions in its own name and
otherwise enforce the terms of the Mortgage Loan and deposit or credit the Net
Liquidation Proceeds, exclusive of Foreclosure Profits, received with respect
thereto in the Collection Account. In the event that all delinquent payments due
under any such Mortgage Loan are paid by the Mortgagor and any other defaults
are cured then the assignee for collection shall promptly reassign such Mortgage

         Section 3.11 ANNUAL SERVICING REPORT. On or before ________ of each
year, beginning ________, ____, the Servicer at its expense shall cause a firm
of nationally recognized independent public accountants (who may also render
other services to the Servicer) to furnish a report to the Company, the Issuer,

to the effect that such firm has examined certain documents and records relating
to the servicing of mortgage loans by the Servicer during the most recent
calendar year then ended under servicing agreements (including this Servicing
Agreement) substantially similar to this Servicing Agreement and that such
examination, which has been conducted substantially in compliance with the audit
guide for audits of non-supervised mortgagees approved by the Department of
Housing and Urban Development for use by independent public accountants (to the
extent that the procedures in such audit guide are applicable to the servicing
obligations set forth in such agreements), has disclosed no items of
noncompliance with the provisions of this Servicing Agreement which, in the
opinion of such firm, are material, except for such items of non compliance as
shall be set forth in such report. In rendering such statement, such firm may
rely, as to matters relating to direct servicing of mortgage loans by
Subservicers, upon comparable statements for examinations conducted
substantially in the manner described above (rendered within one year of such
statement) of independent public accountants with respect to the related
Subservicer. For purposes of such statement, such firm may conclusively assume
that all servicing agreements among the Company and the Servicer relating to

access to the documentation regarding the Mortgage Loans such access being
afforded without charge but only upon reasonable request and during normal
business hours at the offices of the Servicer. Nothing in this Section 3.12
shall derogate from 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 3.12 as a result
of such obligation shall not constitute a breach of this Section 3.12.

         Section 3.13 MAINTENANCE OF CERTAIN SERVICING INSURANCE POLICIES. The
Servicer shall during the term of its service as servicer maintain in force (i)
a policy or policies of insurance covering errors and omissions in the
performance of its obligations as servicer hereunder and (ii) a fidelity bond in
respect of its officers, employees or agents. Each such policy or policies and
bond shall be at least equal to the coverage that would be required by FNMA or
FHLMC, whichever is greater, for Persons performing servicing for mortgage loans
purchased by such entity.

         Section 3.14 INFORMATION REQUIRED BY THE INTERNAL REVENUE SERVICE
GENERALLY AND REPORTS OF FORECLOSURES AND ABANDONMENTS OF MORTGAGED PROPERTY.
The Servicer shall prepare and deliver all federal and state information reports
when and as required by all applicable state and federal income tax laws. In
particular, with respect to the requirement under Section 6050J of the Code to
the effect that the Servicer or Subservicer shall make reports of foreclosures
and abandonments of any mortgaged property for each year beginning in ____, the

during the previous calendar year in which the Servicer (i) on behalf of the

comparable conversion in full or partial satisfaction of a Mortgage Loan, or

Section 6050H (reports relating to mortgage interest received) of the Code.

         Section 3.15 OPTIONAL REPURCHASE OF DEFAULTED MORTGAGE LOANS.

its obligations and duties hereunder. The Servicer shall not be under any
obligation to appear in, prosecute or defend any legal action which is not

liability; PROVIDED, HOWEVER, that the Servicer may in its sole discretion
undertake any such action which it may deem necessary or desirable in respect of
this Servicing Agreement, and the rights and duties of the parties hereto and
the interests of the Securityholders hereunder. In such event, the reasonable
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Company, and the Servicer shall
be entitled to be reimbursed therefor. The Servicer's right to indemnity or
reimbursement pursuant to this Section 6.03 shall survive any resignation or
termination of the Servicer pursuant to Section 6.04 or 7.01 with respect to any

termination (or arising from events that occurred prior to such resignation or
termination).

activities carried on by it or its subsidiaries or Affiliates, the other
activities of the Servicer so causing such a conflict being of a type and nature
carried on by the Servicer or its subsidiaries or Affiliates at the date of this
Servicing Agreement or (ii) upon satisfaction of the following conditions: (a)
the Servicer has proposed a successor servicer to the Company, the Administrator
and the Indenture Trustee in writing and such proposed successor servicer is
reasonably acceptable to the Company, the Administrator, the Indenture Trustee
and the Credit Enhancer; (b) each Rating Agency shall have delivered a letter to
the Company, the Credit Enhancer and the Indenture Trustee prior to the
appointment of the successor servicer stating that the proposed appointment of
such successor servicer as Servicer hereunder will not result in the reduction
or withdrawal of the then current rating of the Securities; and (c) such
proposed successor servicer is reasonably acceptable to the Credit Enhancer, as
evidenced by a letter to the Company and the Indenture Trustee; PROVIDED,
HOWEVER, that no such resignation by the Servicer shall become effective until
such successor servicer or, in the case of (i) above, the Indenture Trustee, as
pledgee of the Mortgage Collateral, shall have assumed the Servicer's
responsibilities and obligations hereunder or the Indenture Trustee, as pledgee
of the Mortgage Collateral, shall have designated a successor servicer in

         Section 6.05 DELEGATION OF DUTIES. In the ordinary course of business,
the Servicer at any time may delegate any of its duties hereunder to any Person,
including any of its Affiliates, who agrees to conduct such duties in accordance
with standards comparable to those with which the Servicer complies pursuant to
Section 3.01. Such delegation shall not relieve the Servicer of its liabilities
and responsibilities with respect to such duties and shall not constitute a
resignation within the meaning of Section 6.04.

         Section 6.06 SERVICER TO PAY INDENTURE TRUSTEE'S AND OWNER TRUSTEE'S
FEES AND EXPENSES; INDEMNIFICATION. (a) The Servicer covenants and agrees to pay

the trusts created under the Trust Agreement and the Indenture and in the
exercise and performance of any of the powers and duties under the Trust
Agreement or the Indenture, as the case may be, of the Owner Trustee, the
Indenture Trustee and any co-trustee, and the Servicer will pay or reimburse the
Indenture Trustee and any co-trustee upon request for all reasonable expenses,
disbursements and advances incurred or made by the Indenture Trustee or any
co-trustee in accordance with any of the provisions of this Servicing Agreement

negligence or bad faith.

         (b) The Servicer agrees to indemnify the Indenture Trustee and the
Owner Trustee for, and to hold the Indenture Trustee and the Owner Trustee, as
the case may be, harmless against, any loss, liability or expense incurred
without negligence or willful misconduct on its part, arising out of, or in
connection with, the acceptance and administration of the Company and the assets
thereof, including the costs and expenses (including reasonable legal fees and
expenses) of defending itself against any claim in connection with the exercise
or performance of any of its powers or duties under any Basic Document, provided
that:

                           (i) with respect to any such claim, the Indenture
         Trustee or Owner Trustee, as the case may be, shall have given the
         Servicer written notice thereof promptly after the Indenture Trustee or
         Owner Trustee, as the case may be, shall have actual knowledge thereof;

                           (ii) while maintaining control over its own defense,
         the Company, the Indenture Trustee or Owner Trustee, as the case may
         be, shall cooperate and consult fully with the Servicer in preparing
         such defense; and

                           (iii) notwithstanding anything in this Servicing
         Agreement to the contrary, the Servicer shall not be liable for
         settlement of any claim by the Indenture Trustee or the Owner Trustee,
         as the case may be, entered into without the prior consent of the
         Servicer, which consent shall not be unreasonably withheld.

the Noteholders or Certificateholders, as the case may be, pursuant to the terms
of this Servicing Agreement.

         be remedied, and stating that such notice is a "Notice of Default"
         hereunder, shall have been given to the Servicer by the Company, the

                           (iii) The entry against the Servicer of a decree or

                           (v) Any failure by the Seller (so long as the Seller
         is the Servicer) or the Servicer, as the case may be, to pay when due
         any amount payable by it under the terms of the Insurance Agreement
         which continues unremedied for a period of three (3) Business Days
         after the date upon which written notice of such failure shall have
         been given to the Seller (so long as the Seller is the Servicer) or the
         Servicer, as the case may be; or

                           (vi) Failure on the part of the Seller or the
         Servicer to duly perform in any material respect any covenant or

         case materially and adversely affects the interests of the Credit
         Enhancer and continues unremedied for a period of 60 days after the
         date on which written notice of such failure, requiring the same to be
         remedied, shall have been given to the Depositor, the Indenture
         Trustee, the Seller or the Servicer, as the case may be, by the Credit
         Enhancer.

then, and in every such case, other than that set forth in (vi) hereof, so long
as a Servicing Default shall not have been remedied by the Servicer, either the
Company, subject to the direction of the Indenture Trustee as pledgee of the
Mortgage Collateral, with the consent of the Credit Enhancer, or the Credit
Enhancer, by notice then given in writing to the Servicer (and to the Company
and the Issuer if given by the Credit Enhancer) and in the case of the event set
forth in (vi) hereof, the Credit Enhancer with the consent of Securityholders at
least 51% of the aggregate Principal Balance of the Notes and the Certificates
may terminate all of the rights and obligations of the Servicer as servicer
under this Servicing Agreement other than its right to receive servicing
compensation and expenses for servicing the Mortgage Loans hereunder during any
period prior to the date of such termination and the Company, subject to the
direction of the Indenture Trustee as pledgee of the Mortgage Collateral, with
the consent of the Credit Enhancer, or the Credit Enhancer may exercise any and
all other remedies available at law or equity. Any such notice to the Servicer
shall also be given to each Rating Agency, the Credit Enhancer, the Company and
the Issuer. On or after the receipt by the Servicer of such written notice, all
authority and power of the Servicer under this Servicing Agreement, whether with
respect to the Securities or the Mortgage Loans or otherwise, shall pass to and
be vested in the Company, subject to the direction of the Indenture Trustee as
pledgee of the Mortgage Collateral, pursuant to and under this Section 7.01;
and, without limitation, the Company is hereby authorized and empowered to
execute and deliver, on behalf of the Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement of each
Mortgage Loan and related documents, or otherwise. The Servicer agrees to
cooperate with the Company in effecting the termination of the responsibilities
and rights of the Servicer hereunder, including, without limitation, the
transfer to the Indenture Trustee for the administration by it of all cash
amounts relating to the Mortgage Loans that shall at the time be held by the
Servicer and to be deposited by it in the Collection Account, or that have been
deposited by the Servicer in the Collection Account or thereafter received by
the Servicer with respect to the Mortgage Loans. All reasonable costs and
expenses (including, but not limited to, attorneys' fees) incurred in connection
with amending this Servicing Agreement to reflect such succession as Servicer
pursuant to this Section 7.01 shall be paid by the predecessor Servicer (or if
the predecessor Servicer is the Indenture Trustee, the initial Servicer) upon
presentation of reasonable documentation of such costs and expenses.



                                      -26-

         Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a payment on a Mortgage Loan which was due prior to the notice terminating
the Servicer's rights and obligations hereunder and received after such notice,
that portion to which the Servicer would have been entitled pursuant to Sections
3.03 and 3.09 as well as its Servicing Fee in respect thereof, and any other
amounts payable to the Servicer hereunder the entitlement to which arose prior
to the termination of its activities hereunder.

         Notwithstanding the foregoing, a delay in or failure of performance
under Section 7.01(i) or under Section 7.01(ii) after the applicable grace
periods specified in such Sections, shall not constitute a Servicer Default if
such delay or failure could not be prevented by the exercise of reasonable
diligence by the Servicer and such delay or failure was caused by an act of God
or the public enemy, acts of declared or undeclared war, public disorder,
rebellion or sabotage, epidemics, landslides, lightning, fire, hurricanes,
earthquakes, floods or similar causes. The preceding sentence shall not relieve
the Servicer from using reasonable efforts to perform its respective obligations
in a timely manner in accordance with the terms of this Servicing Agreement and
the Servicer shall provide the Indenture Trustee, the Credit Enhancer and the
Securityholders with notice of such failure or delay by it, together with a
description of its efforts to so perform its obligations. The Servicer shall
immediately notify the Indenture Trustee, the Credit Enhancer and the Owner
Trustee in writing of any Servicer Default.

         Section 7.02 INDENTURE TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) On
and after the time the Servicer receives a notice of termination pursuant to
Section 7.01 or sends a notice pursuant to Section 6.04, the Indenture Trustee
on behalf of the Noteholders shall be the successor in all respects to the
Servicer in its capacity as servicer under this Servicing Agreement and the
transactions set forth or provided for herein and shall be subject to all the
responsibilities, duties and liabilities relating thereto placed on the Servicer
by the terms and provisions hereof. Nothing in this Servicing Agreement or in
the Trust Agreement shall be construed to permit or require the Indenture
Trustee to (i) succeed to the responsibilities, duties and liabilities of the
initial Servicer in its capacity as Seller under the Mortgage Loan Purchase
Agreement, (ii) be responsible or accountable for any act or omission of the
Servicer prior to the issuance of a notice of termination hereunder, (iii)
require or obligate the Indenture Trustee, in its capacity as successor
Servicer, to purchase, repurchase or substitute any Mortgage Loan, (iv) fund any
losses on any Eligible Investment directed by any other Servicer, or (v) be
responsible for the representations and warranties of the Servicer. As
compensation therefor, the Indenture Trustee shall be entitled to such
compensation as the Servicer would have been entitled to hereunder if no such
notice of termination had been given. Notwithstanding the above, (i) if the
Indenture Trustee is unwilling to act as successor Servicer, or (ii) if the
Indenture Trustee is legally unable so to act, the Indenture Trustee on behalf
of the Mortgage Collateral holders may (in the situation described in clause
(i)) or shall (in the situation described in clause (ii)) appoint or petition a
court of competent jurisdiction to appoint any established housing and home
finance institution, bank or other mortgage loan or home equity loan servicer
having a net worth of not less than $10,000,000 as the successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder; provided that any such successor
Servicer shall be acceptable to the Credit Enhancer, as evidenced by the Credit
Enhancer's prior written consent which consent shall not be unreasonably
withheld and provided further that the appointment of any such successor
Servicer will not result in the qualification, reduction or withdrawal of the
ratings assigned to the Securities by the Rating


                                      -27-

Agencies. Pending appointment of a successor to the Servicer hereunder, unless
the Indenture Trustee is prohibited by law from so acting, the Indenture Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the successor shall be entitled to receive
compensation out of payments on Mortgage Loans in an amount equal to the
compensation which the Servicer would otherwise have received pursuant to
Section 3.09 (or such lesser compensation as the Indenture Trustee and such
successor shall agree). The appointment of a successor Servicer shall not affect
any liability of the predecessor Servicer which may have arisen under this
Servicing Agreement prior to its termination as Servicer (including, without
limitation, the obligation to purchase Mortgage Loans pursuant to Section 3.01,
to pay any deductible under an insurance policy pursuant to Section 3.04 or to
indemnify the Indenture Trustee pursuant to Section 6.06), nor shall any
successor Servicer be liable for any acts or omissions of the predecessor
Servicer or for any breach by such Servicer of any of its representations or
warranties contained herein or in any related document or agreement. The
Indenture Trustee and such successor shall take such action, consistent with
this Servicing Agreement, as shall be necessary to effectuate any such
succession.

         (b) Any successor, including the Indenture Trustee on behalf of the
Noteholders, to the Servicer as servicer shall during the term of its service as
servicer (i) continue to service and administer the Mortgage Loans for the
benefit of the Securityholders, (ii) maintain in force a policy or policies of
insurance covering errors and omissions in the performance of its obligations as
Servicer hereunder and a fidelity bond in respect of its officers, employees and
agents to the same extent as the Servicer is so required pursuant to Section
3.13.

         (c) Any successor Servicer, including the Indenture Trustee on behalf
of the Mortgage Collateral holders, shall not be deemed in default or to have
breached its duties hereunder if the predecessor Servicer shall fail to deliver
any required deposit to the Collection Account or otherwise cooperate with any
required servicing transfer or succession hereunder.

         Section 7.03 NOTIFICATION TO SECURITYHOLDERS. Upon any termination or
appointment of a successor to the Servicer pursuant to this Article VII or
Section 6.04, the Indenture Trustee shall give prompt written notice thereof to
the Securityholders, the Credit Enhancer, the Company, the Issuer and each
Rating Agency.

required to be taken by the Issuer pursuant to the Trust Agreement and by the
Indenture Trustee pursuant to the Indenture following the earlier of:

                           (i) the date on or before which the Indenture or
         Trust Agreement is terminated, or

                           (ii) the purchase by the Servicer from the Company of
         all Mortgage Loans and all property acquired in respect of any Mortgage
         Loan at a price equal to the greater of (a) 100% of the unpaid
         Principal Balance of each Mortgage Loan, plus accrued and unpaid
         interest thereon at the Weighted Average Net Mortgage Rate up to the
         day preceding the Payment Date on which such amounts are to be
