Loan, or such default is, in the judgment of the Servicer, imminent,
and the Servicer has the consent of the Purchaser) the Servicer
shall not permit any modification with respect to any Mortgage Loan

such Fidelity Bond and Errors and Omissions Insurance Policy and a
statement from the surety and the insurer that such Fidelity Bond
and Errors and Omissions Insurance Policy shall in no event be
terminated or materially modified without 30 days' prior written
notice to such Master Servicer, Purchaser, or its designee.

(i) The fifth paragraph of Subsection 11.12 of the Sale and
Servicing Agreement is hereby amended and restated in its entirety as
follows:


5
<PAGE>


"With respect to any REO Property, the deed or certificate of
sale shall be taken in the name of the Purchaser, or its designee.
The Trustee's name shall be placed on the title to such REO Property
solely as the Trustee hereunder and not in its individual capacity.
The Servicer shall ensure that the title to such REO Property
references the Agreement and the Purchaser's (or its designee's)
capacity thereunder. Pursuant to its efforts to sell such REO
Property, the Servicer shall either itself or through an agent
selected by the Servicer protect and conserve such REO Property in
the same manner and to such extent as is customary in the locality
where such REO Property is located and may, incident to its
conservation and protection of the interests of the Purchaser, or
its designee, rent the same, or any part thereof, as the Servicer
deems to be in the best interest of the Purchaser, or its designee,
for the period prior to the sale of such REO Property. The Servicer
shall prepare for and deliver to the Purchaser, or its designee, a
statement with respect to each REO Property that has been rented
showing the aggregate rental income received and all expenses
incurred in connection with the maintenance of such REO Property at
such times as is necessary to enable the Purchaser, or its designee,
to comply with the reporting requirements of the REMIC Provisions.
The net monthly rental income, if any, from such REO Property shall
be deposited in the Certificate Account no later than the close of
business on each Determination Date. 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 any tax reporting
required by Section 6050P of the Code with respect to the
cancellation of indebtedness by certain financial entities, by
preparing such tax and information returns as may be required, in
the form required, and delivering the same to the Purchaser, or its
designee, for filing.

In the event that the Purchaser, or its designee, acquires any
Mortgaged Property as aforesaid or otherwise in connection with a
default or imminent default on a Mortgage Loan, the Servicer shall
dispose of such Mortgaged Property as soon as practicable in a
manner that maximizes the Liquidation Proceeds thereof, but in no
event later than three years after its acquisition by the Purchaser,
or its designee, unless (x) the Servicer obtains an extension of
REMIC status from the Internal Revenue Service or (y) the Purchaser,
or its designee, shall have been supplied with an Opinion of Counsel
to the effect that the holding by the Purchaser, or its designee, of
such Mortgaged Property subsequent to a three-year period, if
applicable, will not result in the imposition of taxes on
"prohibited transactions" of any REMIC as defined in section 860F of
the Code or cause any REMIC to fail to qualify as a REMIC at any
time, the Purchaser, or its designee, may continue to hold such
Mortgaged Property (subject to any conditions contained in such
Opinion of Counsel) after the expiration of such three-year period.
Notwithstanding any other provision of this Agreement, no Mortgaged
Property acquired by the Purchaser, or its designee, shall be rented
(or allowed to continue to be rented) or otherwise used for the
production of income by or on behalf of the Purchaser, or its
designee, in such a manner or pursuant to any terms that would (i)
cause such Mortgaged Property to fail to qualify as "foreclosure
property" within the meaning of section 860G(a)(8) of the Code or
(ii) subject any REMIC to the imposition of any federal, state or
local income taxes on the income earned from such Mortgaged Property
under Section 860G(c) of the Code or otherwise, unless the Servicer
has agreed to indemnify


6
<PAGE>


and hold harmless the Purchaser, or its designee, with respect to
the imposition of any such taxes."

(j) The first sentence of Subsection 11.15 of the Sale and Servicing
Agreement is hereby amended and restated in its entirety as follows:

"Statements to the Master Servicer. Not later than the tenth
calendar day of each month (or, if such 10th day is not a Business
Day, the following Business Day) the Servicer shall furnish to the
Master Servicer in electronic format a statement providing loan
level accounting data for the period ending on the last Business Day
of the preceding month in the format mutually agreed to between the
Servicer and the Master Servicer. The information required shall
consist of that which is substantially in the form of Exhibit II
hereto or such other form as may be mutually agreed upon by the
Servicer and the Master Servicer, taking into consideration the
status of the subject loans and the availability of the requested
information.

(k) Subsection 11.19 and Subsection 11.20 of the Sale and Servicing
Agreement are hereby deleted.

(l) Subsection 12.01(b) of the Sale and Servicing Agreement is
hereby amended and restated in its entirety as follows:

"failure by the Servicer to duly observe or perform, in any material
respect, any other covenants, obligations or agreements of the
Servicer as set forth in this Agreement which failure continues
unremedied for a period of sixty (60) days (or, in the case of the

date on which written notice of such failure requiring the same to
be remedied, shall have been given to the Servicer by any party to
this Agreement or by any master servicer responsible for master
servicing the Mortgage Loans pursuant to a securitization of such
Mortgage Loans;"

(n) The first sentence of Subsection 13.01 of the Sale and Servicing
Agreement is hereby amended and restated in its entirety as follows:

of the Servicer, as servicer, shall terminate upon (a) the
distribution to the Purchaser of the final payment or liquidation
with respect to the last Mortgage Loan (or advances of same by the
Servicer); or (b) the disposition of all property acquired upon
