                  The Depositor, concurrently with the execution and delivery

         the customary evidence of title.

and (II) with respect to each Mortgage Loan that is a Cooperative Loan so
transferred and assigned:

                  (i) The Mortgage Note, endorsed by manual or facsimile

                  (v) The original executed security agreement or similar
                  document and all assignments thereof showing a complete chain
                  of assignment from the named secured party to the Trustee;

                  (vi) Except for Mortgage Loans (x) secured by Mortgaged

                  State of New York, the executed UCC-1 financing statement with
                  evidence of recording thereon and executed original UCC-3
                  financing statements or other appropriate UCC financing
                  statements required by state law, evidencing a complete and
                  unbroken chain from the mortgagee to the Trustee with evidence
                  of recording thereon (or in a form suitable for recordation);
                  and

                  (viii) Any original assumption, modification or buydown
                  agreement applicable to the Mortgage Loan.

                  In instances where an original recorded Mortgage cannot be
delivered by the Depositor to the Trustee (or a custodian on behalf of the
Trustee) prior to or concurrently with the execution and delivery of this
Agreement, due to a delay in connection with the recording of such Mortgage or
power of attorney, the Depositor may, (a) in lieu of delivering such original
recorded Mortgage or power of attorney referred to in clause (I)(ii) above,
deliver to the Trustee (or a

                                       51
<PAGE>

custodian on behalf of the Trustee) a copy thereof, provided that the Depositor
certifies that the original Mortgage has been delivered to a title insurance
company for recordation after receipt of its policy of title insurance or binder
therefor (which may be a certificate relating to a master policy of title
insurance), and (b) in lieu of delivering the completed assignment in recordable
form referred to in clause (iii) above to the Trustee (or a custodian on behalf
of the Trustee), deliver such assignment to the Trustee (or a custodian on
behalf of the Trustee) completed except for recording information. In all such
instances, the Depositor will deliver the original recorded Mortgage and
completed assignment (if applicable) to the Trustee (or a custodian on behalf of
the Trustee) promptly upon receipt of such Mortgage. In instances where an
original recorded Mortgage has been lost or misplaced, the Depositor or the
related title insurance company may deliver, in lieu of such Mortgage, a copy of
such Mortgage bearing recordation information and certified as true and correct
by the office in which recordation thereof was made. In instances where the
original or a copy of the title insurance policy referred to in clause (I)(v)
above (which may be a certificate relating to a master policy of title
insurance) pertaining to the Mortgaged Property relating to a Mortgage Loan
cannot be delivered by the Depositor to the Trustee (or a custodian on behalf of
the Trustee) prior to or concurrently with the execution and delivery of this
Agreement because such policy is not yet available, the Depositor may, in lieu
of delivering the original or a copy of such title insurance, deliver to the
Trustee (or a custodian on behalf of the Trustee) a binder with respect to such
policy (which may be a certificate relating to a master policy of title
insurance) and deliver the original or a copy of such policy (which may be a
certificate relating to a master policy of title insurance) to the Trustee (or a
custodian on behalf of the Trustee) within 270 days of the Closing Date, in
instances where an original assumption, modification or buydown agreement cannot
be delivered by the Depositor to the Trustee (or a custodian on behalf of the
Trustee) prior to or concurrently with the execution and delivery of this
Agreement, the Depositor may, in lieu of delivering the original of such
agreement, deliver a certified copy thereof.

                  To the extent not already recorded, the Master Servicer, at
the expense of the Sellers shall promptly (and in no event later than five
Business Days following the later of the Closing Date and the date of receipt by
the Master Servicer of the recording information for a Mortgage) submit or cause
to be submitted for recording, at no expense to REMIC I, in the appropriate
public office for real property records, each Assignment delivered to it
pursuant to (I)(iii) above. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Master Servicer, at the
expense of the Sellers, shall promptly prepare or cause to be prepared a
substitute Assignment or cure or cause to be cured such defect, as the case may
be, and thereafter cause each such Assignment to be duly recorded.

                  Notwithstanding the foregoing, for administrative convenience
and facilitation of servicing and to reduce closing costs, the Assignments shall
not be required to be submitted for recording (except with respect to any
Mortgage Loan located in Florida and Maryland) unless such failure to record
would result in a withdrawal or a downgrading by any Rating Agency of the rating
on any Class of Certificates. Notwithstanding the foregoing, the Master Servicer
shall submit each Assignment for recording, at no expense to the Trust Fund or
the Master Servicer, upon the earliest to occur of: (i) reasonable direction by
Holders of Certificates entitled to at least 25% of the Voting Rights, (ii) the
occurrence of a Master Servicer Event of Default, (iii) the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Seller, (iv) the
occurrence of a servicing transfer as described in Section 7.02 of this
Agreement and (v) with respect to any one Assignment the

                                       52
<PAGE>

occurrence of a foreclosure relating to the Mortgagor under the related
Mortgage. Notwithstanding the foregoing, if the Sellers fail to pay the cost of
recording the Assignments, such expense will be paid by the Master Servicer and
the Master Servicer shall be reimbursed for such expenses by the Trust Fund as
set forth herein.

                  In connection with its servicing of Cooperative Loans and as
required by law, the Master Servicer will use its best efforts to file timely
continuation statements with regard to each financing statement and assignment
relating to Cooperative Loans as to which the related Cooperative Unit is
located outside of the State of New York.

                  With respect to a maximum of approximately 1.00% of the
Original Mortgage Loans, by outstanding principal balance of the Original
Mortgage Loans as of the Cut-off Date, if any original Mortgage Note referred to
in (I)(i) or (II)(i) above cannot be located, the obligations of the Depositor
to deliver such documents shall be deemed to be satisfied upon delivery to the
Trustee (or a custodian on behalf of the Trustee) of a photocopy of such
Mortgage Note, if available, with a lost note affidavit. If any of the original
Mortgage Notes for which a lost note affidavit was delivered to the Trustee (or
a custodian on behalf of the Trustee) is subsequently located, such original
Mortgage Note shall be delivered to the Trustee (or a custodian on behalf of the
Trustee) within three Business Days.

                  The Depositor shall deliver or cause to be delivered to the
Trustee (or a custodian on behalf of the Trustee) promptly upon receipt thereof
any other original documents constituting a part of a Mortgage File received
with respect to any Mortgage Loan, including, but not limited to, any original
documents evidencing an assumption, modification, consolidation or extension of
any Mortgage Loan.

                  All original documents relating to the Mortgage Loans that are
not delivered to the Trustee (or a custodian on behalf of the Trustee) are and
shall be held by or on behalf of the Sellers, the Depositor or the Master
Servicer, as the case may be, in trust for the benefit of the Trustee on behalf
of the Certificateholders. In the event that any such original document is
required pursuant to the terms of this Section to be a part of a Mortgage File,
such document shall be delivered promptly to the Trustee (or a custodian on
behalf of the Trustee). Any such original document delivered to or held by the
Depositor that is not required pursuant to the terms of this Section to be a
part of a Mortgage File, shall be delivered promptly to the Master Servicer.

                  Wherever it is provided in this Section 2.01 that any
document, evidence or information relating to a Mortgage Loan be delivered or
supplied to the Trustee, the Depositor shall do so by delivery thereof to the
Trustee or a custodian on behalf of the Trustee.

                  SECTION 2.02. Acceptance of REMIC I by the Trustee.

                  Subject to the provisions of Section 2.01 and subject to any
exceptions noted on an exception report delivered by or on behalf of the
Trustee, the Trustee acknowledges receipt of the documents referred to in
Section 2.01 (other than such documents described in Sections 2.01(v) above and
all other assets included in the definition of "REMIC I" to the extent of
amounts deposited into the Distribution Account) and declares that it holds and
will hold such documents and the other

                                       53
<PAGE>

documents delivered to it constituting the Mortgage File, and that it holds or
will hold all such assets and such other assets included in the definition of
"REMIC I" in trust for the exclusive use and benefit of all present and future
Certificateholders.

                  On or prior to the Closing Date, the Trustee agrees, for the
benefit of the Certificateholders, to execute and deliver to the Depositor and
the Master Servicer an acknowledgment of receipt of each Mortgage Note (with any
exceptions noted), substantially in the form attached as Exhibit C-3 hereto.

                  The Trustee agrees, for the benefit of the Certificateholders,
to review, or that it has reviewed pursuant to Section 2.01 each Mortgage File
on or prior to the Closing Date, with respect to each Mortgage Loan (or, with
respect to any document delivered after the Startup Day, within 90 days of
receipt and with respect to any Qualified Substitute Mortgage, within 90 days
after the assignment thereof). The Trustee further agrees, for the benefit of
the Certificateholders, to certify in substantially the form attached hereto as
Exhibit C-1, within 90 days following the date on which the Trustee receives the
remaining contents of each Mortgage File from the Depositor, with respect to
each Mortgage Loan (or, with respect to any document delivered after the Startup
Day, within 90 days of receipt and with respect to any Qualified Substitute
Mortgage, within 90 days after the assignment thereof) that, as to each Mortgage
Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in
full or any Mortgage Loan specifically identified in the exception report
annexed thereto as not being covered by such certification), (i) all documents
required to be delivered to it pursuant Section 2.01 of this Agreement are in
its possession, (ii) such documents have been reviewed by it and have not been
mutilated, damaged or torn and relate to such Mortgage Loan and (iii) based on
its examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule that corresponds to items (i), (iii) and (xiv) of the
Mortgage Loan Schedule accurately reflects information set forth in the Mortgage
File. It is herein acknowledged that, in conducting such review, the Trustee is
under no duty or obligation to inspect, review or examine any such documents,
instruments, certificates or other papers to determine that they are genuine,
enforceable, or appropriate for the represented purpose or that they have
actually been recorded or that they are other than what they purport to be on
their face.

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

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

                                       54
<PAGE>

                  The Trustee may, concurrently with the execution and delivery
hereof or at any time thereafter, enter into a custodial agreement with a
custodian pursuant to which the Trustee appoints a custodian to hold the
Mortgage Files on behalf of the Trustee for the benefit of all present and
future Certificateholders, which may provide that the custodian shall, on behalf
of the Trustee, and as the Trustee's agent, conduct the review of each Mortgage
File required under the first paragraph of this Section 2.02, provided that, if
the custodian so appointed is the Depositor or an Affiliate of the Depositor,
the Trustee shall conduct such review.

                  SECTION 2.03. Repurchase or Substitution of Mortgage Loans by
                                the Sellers or the Depositor.

                  (a) Upon discovery or receipt of notice of any materially
defective document in, or that a document is missing from, a Mortgage File or of
the breach by the Sellers of any representation, warranty or covenant under the
Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which
materially adversely affects the value of such Mortgage Loan or the interest
therein of the Certificateholders, the Trustee shall promptly notify the
Sellers, the Trust Administrator and the Master Servicer of such defect, missing
document or breach and request that the Sellers deliver such missing document or
cure such defect or breach within 90 days from the date the Sellers were
notified of such missing document, defect or breach, and if the Sellers do not
deliver such missing document or cure such defect or breach in all material
respects during such period, the Master Servicer shall enforce the obligations
of the Sellers under the Mortgage Loan Purchase Agreement to repurchase such
Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date
on which the Sellers were notified (subject to Section 2.03(e)) of such missing
document, defect or breach, if and to the extent that the Sellers are obligated
to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the
repurchased Mortgage Loan shall be deposited in the Collection Account, and the
Trustee, upon receipt of written certification from the Master Servicer of such
deposit, shall release to the Sellers the related Mortgage File and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as the Sellers shall furnish to it and as shall be necessary
to vest in the Sellers any Mortgage Loan released pursuant hereto, and the
Trustee shall have no further responsibility with regard to such Mortgage File.
In lieu of repurchasing any such Mortgage Loan as provided above, if so provided
in the Mortgage Loan Purchase Agreement, the Sellers may cause such Mortgage
Loan to be removed from REMIC I (in which case it shall become a Deleted
Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in
the manner and subject to the limitations set forth in Section 2.03(d). It is
understood and agreed that the obligation of the Sellers to cure or to
repurchase (or to substitute for) any Mortgage Loan as to which a document is
missing, a material defect in a constituent document exists or as to which such
a breach has occurred and is continuing shall constitute the sole remedy
respecting such omission, defect or breach available to the Trustee on behalf of
the Certificateholders.

                  (b) Reserved.

                  (c) Within 90 days of the earlier of discovery by the Master
Servicer or receipt of notice by the Master Servicer of the breach of any
representation, warranty or covenant of the Master Servicer set forth in Section
2.05 which materially and adversely affects the interests of the

                                       55
<PAGE>

Certificateholders in any Mortgage Loan, the Master Servicer shall cure such
breach in all material respects.

                  (d) Any substitution of Qualified Substitute Mortgage Loans
for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected
prior to the date which is two years after the Startup Day for REMIC I.

                  As to any Deleted Mortgage Loan for which the Sellers
substitute a Qualified Substitute Mortgage Loan or Loans, such substitution
shall be effected by the Sellers delivering to the Trustee, for such Qualified
Substitute Mortgage Loan or Loans, the documents and agreements, with all
necessary endorsements thereon, as are required by Section 2.01, together with
an Officers' Certificate providing that each such Qualified Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution Shortfall
Amount (as described below), if any, in connection with such substitution. The
Trustee shall acknowledge receipt for such Qualified Substitute Mortgage Loan or
Loans and, within ten Business Days thereafter, review such documents as
specified in Section 2.02 and deliver to the Depositor, the Master Servicer and
the Trust Administrator, with respect to such Qualified Substitute Mortgage Loan
or Loans, a certification substantially in the form attached hereto as Exhibit
C-1, with any applicable exceptions noted thereon. Within one year of the date
of substitution, the Trustee shall deliver to the Depositor, the Master Servicer
and the Trust Administrator a certification substantially in the form of Exhibit
C-2 hereto with respect to such Qualified Substitute Mortgage Loan or Loans,
with any applicable exceptions noted thereon. For the month of substitution,
distributions to Certificateholders will reflect the Monthly Payment due on such
Deleted Mortgage Loan on or before the Due Date in the month of substitution,
and the Sellers shall thereafter be entitled to retain all amounts subsequently
received in respect of such Deleted Mortgage Loan. The Depositor shall give or
cause to be given written notice to the Certificateholders that such
substitution has taken place, shall amend the Mortgage Loan Schedule to reflect
the removal of such Deleted Mortgage Loan from the terms of this Agreement and
the substitution of the Qualified Substitute Mortgage Loan or Loans and shall
deliver a copy of such amended Mortgage Loan Schedule to the Trustee and the
Trust Administrator. Upon such substitution, such Qualified Substitute Mortgage
Loan or Loans shall constitute part of the Mortgage Pool and shall be subject in
all respects to the terms of this Agreement and the Mortgage Loan Purchase
Agreement, including all applicable representations and warranties thereof
included in the Mortgage Loan Purchase Agreement.

                  For any month in which the Sellers substitute one or more
Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Master Servicer will determine the amount (the "Substitution Shortfall Amount"),
if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans
exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan,
the Scheduled Principal Balance thereof as of the date of substitution, together
with one month's interest on such Scheduled Principal Balance at the applicable
Net Mortgage Rate. On the date of such substitution, the Sellers will deliver or
cause to be delivered to the Master Servicer for deposit in the Collection
Account an amount equal to the Substitution Shortfall Amount, if any, and the
Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans
and certification by the Master Servicer of such deposit, shall release to the
Sellers the related Mortgage File or Files and shall execute and deliver such
instruments of transfer or assignment, in each case

                                       56
<PAGE>

without recourse, as the Sellers shall deliver to it and as shall be necessary
to vest therein any Deleted Mortgage Loan released pursuant hereto.

                  In addition, the Sellers shall obtain at their own expense and
deliver to the Trustee and the Trust Administrator an Opinion of Counsel to the
effect that such substitution will not cause (a) any federal tax to be imposed
on any Trust REMIC, including without limitation, any federal tax imposed on
"prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup date" under Section 860G(d)(1) of the Code, or
(b) any Trust REMIC to fail to qualify as a REMIC at any time that any
Certificate is outstanding.

                  (e) Upon discovery by the Depositor, the Sellers, the Master
Servicer, the Trust Administrator or the Trustee that any Mortgage Loan does not
constitute a "qualified mortgage" within the meaning of Section 860G(a)(3) of
the Code, the party discovering such fact shall within two Business Days give
written notice thereof to the other parties. In connection therewith, the
Sellers or the Depositor shall repurchase or, subject to the limitations set
forth in Section 2.03(d), substitute one or more Qualified Substitute Mortgage
Loans for the affected Mortgage Loan within 90 days of the earlier of discovery
or receipt of such notice with respect to such affected Mortgage Loan. Such
repurchase or substitution shall be made by (i) the Sellers, if the affected
Mortgage Loan's status as a non-qualified mortgage is or results from a breach
of any representation, warranty or covenant made by the Sellers under the
Mortgage Loan Purchase Agreement, or (ii) the Depositor, if the affected
Mortgage Loan's status as a non-qualified mortgage is a breach of no
representation or warranty. Any such repurchase or substitution shall be made in
the same manner as set forth in Sections 2.03(a). The Trustee shall reconvey to
the Depositor or the Sellers, as the case may be, 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.

                  SECTION 2.04. Reserved.

                  SECTION 2.05. Representations, Warranties and Covenants of the
                                Master Servicer.

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

                           (i) The Master Servicer is a corporation duly
                  organized, validly existing and in good standing under the
                  laws of the State of Florida and is duly authorized and
                  qualified (or a Sub-Servicer on behalf of the Master Servicer
                  is duly authorized and qualified) to transact any and all
                  business contemplated by this Agreement to be conducted by the
                  Master Servicer in any state in which a Mortgaged Property is
                  located or is (or such Sub-Servicer is) otherwise not required
                  under applicable law to effect such qualification and, in any
                  event, is (or such Sub-Servicer is) in compliance with, or
                  exempt from, the doing business laws of any such State, to the
                  extent necessary to ensure its ability to enforce each
                  Mortgage Loan and to service the Mortgage Loans in accordance
                  with the terms of this Agreement;

                           (ii) The Master Servicer has the full corporate power
                  and authority to service each Mortgage Loan, and to execute,
                  deliver and perform, and to enter into and consummate the
                  transactions contemplated by this Agreement and has duly
                  authorized by all necessary corporate action on the part of
                  the Master Servicer the execution, delivery and performance of
                  this Agreement; and this Agreement, assuming the due
                  authorization, execution and delivery thereof by the other
                  parties hereto, constitutes a legal, valid and binding
                  obligation of the Master Servicer, enforceable against the
                  Master Servicer in accordance with its terms, except to the
                  extent that (a) the enforceability thereof may be limited by
                  bankruptcy, insolvency, moratorium, receivership and other
                  similar laws relating to creditors' rights generally and (b)
                  the remedy of specific performance and injunctive and other
                  forms of equitable relief may be subject to the equitable
                  defenses and to the discretion of the court before which any
                  proceeding therefor may be brought;

                           (iii) The execution and delivery of this Agreement by
                  the Master Servicer, the servicing of the Mortgage Loans by
                  the Master Servicer hereunder, the consummation of any other
                  of the transactions herein contemplated, and the fulfillment
                  of or compliance with the terms hereof are in the ordinary
                  course of business of the Master Servicer and will not (A)
                  result in a breach of any term or provision of the charter or
                  by-laws of the Master Servicer or (B) conflict with, result in
                  a breach, violation or acceleration of, or result in a default
                  under, the terms of any other material agreement or instrument
                  to which the Master Servicer is a party or by which it may be
                  bound, or any statute, order or regulation applicable to the
                  Master Servicer of any court, regulatory body, administrative
                  agency or governmental body having jurisdiction over the
                  Master Servicer; and the Master Servicer is not a party to,
                  bound by, or in breach or violation of any indenture or other
                  agreement or instrument, or subject to or in violation of any
                  statute, order or regulation of any court, regulatory body,
                  administrative agency or governmental body having jurisdiction
                  over it, which materially and adversely affects or, to the
                  Master Servicer's knowledge, would in the future materially
                  and adversely affect, (x) the ability of the Master Servicer
                  to perform its obligations under this Agreement or (y) the
                  business, operations, financial condition, properties or
                  assets of the Master Servicer taken as a whole;

                           (iv) No litigation is pending against the Master
                  Servicer that would materially and adversely affect the
                  execution, delivery or enforceability of this Agreement or the
                  ability of the Master Servicer to service the Mortgage Loans
                  or to perform any of its other obligations hereunder in
                  accordance with the terms hereof; and

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

                  It is understood and agreed that the representations,
warranties and covenants set forth in this Section 2.05 shall survive delivery
of the Mortgage Files to the Trustee and shall inure to the benefit of the
Trustee, the Trust Administrator, the Depositor and the Certificateholders. Upon
discovery by any of the Depositor, the Master Servicer, the Trust Administrator
or the Trustee of a breach of any of the foregoing representations, warranties
and covenants which materially and adversely affects the value of any Mortgage
Loan or the interests therein of the Certificateholders, the party discovering
such breach shall give prompt written notice (but in no event later than two
Business Days following such discovery) to the Trustee and the Trust
Administrator. Subject to Section 7.01, the obligation of the Master Servicer
set forth in Section 2.03(c) to cure breaches shall constitute the sole remedies
against the Master Servicer available to the Certificateholders, the Depositor,
the Trust Administrator or the Trustee on behalf of the Certificateholders
respecting a breach of the representations, warranties and covenants contained
in this Section 2.05.

                  SECTION 2.06. Issuance of the Certificates.

                  The Trustee acknowledges the assignment to it of the Mortgage
Loans and the delivery to it of the Mortgage Files, subject to the provisions of
Section 2.01 and Section 2.02, together with the assignment to it of all other
assets included in REMIC I delivered on the date hereof, receipt of which is
hereby acknowledged. Concurrently with such assignment and delivery of such
assets delivered on the date hereof and in exchange therefor, the Trust
Administrator, pursuant to the written request of the Depositor executed by an
officer of the Depositor, has executed, authenticated and delivered to or upon
the order of the Depositor, the Certificates in authorized denominations. The
interests evidenced by the Certificates constitute the entire beneficial
ownership interest in REMIC II.

                  SECTION 2.07. Conveyance of the REMIC I Regular Interests;
                                Acceptance of REMIC II by the Trustee.

                  The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey to the
Trustee, without recourse all the right, title and interest of the Depositor in
and to the REMIC I Regular Interests for the benefit of the Class R
Certificateholders (as holder of the Class R-I Interest and Class R-II Interest)
and REMIC II (as holder of the REMIC I Regular Interests). The Trustee
acknowledges receipt of the REMIC I Regular Interests and declares that it holds
and will hold the same in trust for the exclusive use and benefit of all present
and future Class R Certificateholders (as holder of the Class R-I Interest and
Class R-II Interest) and REMIC II (as holder of the REMIC I Regular Interests).
The rights of the Class R Certificateholders (as holder of the Class R-I
Interest and Class R-II Interest) and REMIC II (as holder of the REMIC I Regular
Interest) to receive distributions from the proceeds of REMIC II in respect of
the Class R-II Interest and REMIC II Regular Interests, respectively, and all
ownership interests evidenced or constituted by the Class R-II Interest and the
REMIC I Regular Interests, shall be as set forth in this Agreement.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

                  SECTION 3.01. Master Servicer to Act as Master Servicer.

                  The Master Servicer shall service and administer the Mortgage
Loans on behalf of the Trustee and in the best interests of and for the benefit
of the Certificateholders (as determined by the Master Servicer in its
reasonable judgment) in accordance with the terms of this Agreement and the
respective Mortgage Loans and, to the extent consistent with such terms, in the
same manner in which it services and administers similar mortgage loans for its
own portfolio, giving due consideration to customary and usual standards of
practice of prudent mortgage lenders and loan servicers administering similar
mortgage loans but without regard to:

                           (i) any relationship that the Master Servicer, any
                  Sub-Servicer or any Affiliate of the Master Servicer or any
                  Sub-Servicer may have with the related Mortgagor;

                           (ii) the ownership of any Certificate by the Master
                  Servicer or any Affiliate of the Master Servicer;

                           (iii) the Master Servicer's obligation to make P&I
                  Advances or Servicing Advances; or

                           (iv) the Master Servicer's or any Sub-Servicer's
                  right to receive compensation for its services hereunder or
                  with respect to any particular transaction.

                  To the extent consistent with the foregoing, the Master
Servicer shall also seek to maximize the timely and complete recovery of
principal and interest on the Mortgage Notes. Subject only to the
above-described servicing standards and the terms of this Agreement and of the
respective Mortgage Loans, the Master Servicer shall have full power and
authority, acting alone or through Sub-Servicers as provided in Section 3.02, to
do or cause to be done any and all things in connection with such servicing and
administration which it may deem necessary or desirable. Without limiting the
generality of the foregoing, the Master Servicer in its own name or in the name
of a Sub-Servicer is hereby authorized and empowered by the Trustee when the
Master Servicer believes it appropriate in its best judgment in accordance with
the servicing standards set forth above, to execute and deliver, on behalf of
the Certificateholders and the Trustee, and upon notice to the Trustee and the
Trust Administrator, 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 the Mortgaged Properties and to institute
foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert
the ownership of such properties, and to hold or cause to be held title to such
properties, on behalf of the Trustee and Certificateholders. The Master Servicer
shall service and administer the Mortgage Loans in accordance with applicable
state and federal law and shall provide to the Mortgagors any reports required
to be provided to them thereby. The Master Servicer shall also comply in the
performance of this Agreement with all reasonable

                                       60
<PAGE>

rules and requirements of each insurer under any standard hazard insurance
policy. Subject to Section 3.17, the Trustee shall execute, at the written
request of the Master Servicer, and furnish to the Master Servicer and any
Sub-Servicer such documents as are necessary or appropriate to enable the Master
Servicer or any Sub-Servicer to carry out their servicing and administrative
duties hereunder, and the Trustee hereby grants to the Master Servicer a power
of attorney to carry out such duties. The Trustee shall not be liable for the
actions of the Master Servicer or any Sub-Servicers under such powers of
attorney.

                  In accordance with the standards of the preceding paragraph,
the Master Servicer shall, following consultation with the related Mortgagor,
advance or cause to be advanced funds as necessary for the purpose of effecting
the payment of taxes and assessments on the Mortgaged Properties in a manner and
at a time that avoids the loss of the Mortgaged Property due to a tax sale or
the foreclosure of a tax lien, which advances shall be Servicing Advances
reimbursable in the first instance from related collections from the Mortgagors
pursuant to Section 3.09, and further as provided in Section 3.11. Any cost
incurred by the Master Servicer or by Sub- Servicers in effecting the timely
payment of taxes and assessments on a Mortgaged Property shall not, for the
purpose of calculating distributions to Certificateholders, be added to the
unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit.

                  Notwithstanding anything in this Agreement to the contrary,
the Master Servicer may not make any future advances with respect to a Mortgage
Loan (except as provided in Section 4.03) and the Master Servicer shall not (i)
permit any modification with respect to any Mortgage Loan that would change the
Mortgage Rate, reduce or increase the principal balance (except for reductions
resulting from actual payments of principal) or change the final maturity date
on such Mortgage Loan or (ii) permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (A) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or final,
temporary or proposed Treasury regulations promulgated thereunder) and (B) cause
any Trust REMIC to fail to qualify as a REMIC under the Code or the imposition
of any tax on "prohibited transactions" or "contributions after the startup
date" under the REMIC Provisions. Notwithstanding the foregoing, nothing in this
Agreement shall prohibit a transfer by the Trustee of a Mortgage Loan to the
Sellers upon the refinancing of the Mortgage Loan through a "significant
modification" within the meaning of Section 1001 of the Code. Upon such
refinancing, the Purchase Price shall be deposited into the Collection Account,
and the Trustee, upon receipt of written certification from the Master Servicer
of such deposit, shall release to the Sellers the related Mortgage File and
shall execute and deliver such instruments of transfer or assignment, in each
case without recourse, as the Sellers shall furnish to it and as shall be
necessary to vest in the Sellers any Mortgage Loan released pursuant hereto, and
the Trustee shall have no further responsibility with regard to such Mortgage
Files. The Trustee, the Trust Administrator and the Master Servicer shall treat
any such refinancing as a prepayment in full of such Mortgage Loan for all
purposes of this Agreement.

                  The Master Servicer may delegate its responsibilities under
this Agreement; provided, however, that no such delegation shall release the
Master Servicer from the responsibilities or liabilities arising under this
Agreement.

                  SECTION 3.02. Sub-Servicing Agreements Between the Master
                                Servicer and Sub-Servicers.

                  (a) The Master Servicer may enter into Sub-Servicing
Agreements (provided that such agreements would not result in a withdrawal or a
downgrading by the Rating Agencies of the rating on any Class of Certificates)
with Sub-Servicers, for the servicing and administration of the Mortgage Loans.

                  Each Sub-Servicer shall be (i) authorized to transact business
in the state or states in which the related Mortgaged Properties it is to
service are situated, if and to the extent required by applicable law to enable
the Sub-Servicer to perform its obligations hereunder and under the Sub-
Servicing Agreement and (ii) an institution approved as a mortgage loan
originator by the Federal Housing Administration or an institution the deposit
accounts of which are insured by the FDIC. Each Sub-Servicing Agreement must
impose on the Sub-Servicer requirements conforming to the provisions set forth
in Section 3.08 and provide for servicing of the Mortgage Loans consistent with
the terms of this Agreement. The Master Servicer will examine each Sub-Servicing
Agreement and will be familiar with the terms thereof. The terms of any
Sub-Servicing Agreement will not be inconsistent with any of the provisions of
this Agreement. The Master Servicer and the Sub- Servicers may enter into and
make amendments to the Sub-Servicing Agreements or enter into different forms of
Sub-Servicing Agreements; provided, however, that any such amendments or
different forms shall be consistent with and not violate the provisions of this
Agreement, and that no such amendment or different form shall be made or entered
into which could be reasonably expected to be materially adverse to the
interests of the Certificateholders, without the consent of the Holders of
Certificates entitled to at least 66% of the Voting Rights. Any variation
without the consent of the Holders of Certificates entitled to at least 66% of
the Voting Rights from the provisions set forth in Section 3.08 relating to
insurance or priority requirements of Sub-Servicing Accounts, or credits and
charges to the Sub- Servicing Accounts or the timing and amount of remittances
by the Sub-Servicers to the Master Servicer, are conclusively deemed to be
inconsistent with this Agreement and therefore prohibited. The Master Servicer
shall deliver to the Trustee and the Trust Administrator copies of all
Sub-Servicing Agreements, and any amendments or modifications thereof, promptly
upon the Master Servicer's execution and delivery of such instruments.

                  Notwithstanding the foregoing, the parties hereto agree that
U.S. Trust Company, N.A. may act as Sub-Servicer pursuant to the terms hereof.

                  (b) As part of its servicing activities hereunder, the Master
Servicer (except as otherwise provided in the last sentence of this paragraph),
for the benefit of the Trustee and the Certificateholders, shall enforce the
obligations of each Sub-Servicer under the related Sub-Servicing Agreement and
of the Sellers under the Mortgage Loan Purchase Agreement, including, without
limitation, any obligation to make advances in respect of delinquent payments as
required by a Sub- Servicing Agreement, or to purchase a Mortgage Loan on
account of missing or defective documentation or on account of a breach of a
representation, warranty or covenant, as described in Section 2.03(a). Such
enforcement, including, without limitation, the legal prosecution of claims,
termination of Sub-Servicing 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 Master Servicer, in its good faith

                                       62
<PAGE>

business judgment, would require were it the owner of the related Mortgage
Loans. The Master 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 Loans, or (ii) from a
specific recovery of costs, expenses or attorneys' fees against the party
against whom such enforcement is directed.

                  SECTION 3.03. Successor Sub-Servicers.

                  The Master Servicer shall be entitled to terminate any
Sub-Servicing Agreement and the rights and obligations of any Sub-Servicer
pursuant to any Sub-Servicing Agreement in accordance with the terms and
conditions of such Sub-Servicing Agreement. In the event of termination of any
Sub-Servicer, all servicing obligations of such Sub-Servicer shall be assumed
simultaneously by the Master Servicer without any act or deed on the part of
such Sub-Servicer or the Master Servicer, and the Master Servicer either shall
service directly the related Mortgage Loans or shall enter into a Sub-Servicing
Agreement with a successor Sub-Servicer which qualifies under Section 3.02.

                  Any Sub-Servicing Agreement shall include the provision that
such agreement may be immediately terminated by the Trustee or the Trust
Administrator without fee, in accordance with the terms of this Agreement, in
the event that the Master Servicer shall, for any reason, no longer be the
Master Servicer (including termination due to a Master Servicer Event of
Default).

                  SECTION 3.04. Liability of the Master Servicer.

                  Notwithstanding any Sub-Servicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Master Servicer and a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall remain obligated and
primarily liable to the Trustee and the Certificateholders for the servicing and
administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
Sub-Servicing Agreements or arrangements or by virtue of indemnification from
the Sub-Servicer and to the same extent and under the same terms and conditions
as if the Master Servicer alone were servicing and administering the Mortgage
Loans. The Master Servicer shall be entitled to enter into any agreement with a
Sub- Servicer for indemnification of the Master Servicer by such Sub-Servicer
and nothing contained in this Agreement shall be deemed to limit or modify such
indemnification.

                  SECTION 3.05. No Contractual Relationship Between
                                Sub-Servicers, Trust Administrator, Trustee or
                                Certificateholders.

                  Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Master Servicer alone, and the Trust Administrator, the Trustee and the
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.06. The Master Servicer shall be solely liable
for all fees owed by it to any Sub-Servicer,

                                       63
<PAGE>

irrespective of whether the Master Servicer's compensation pursuant to this
Agreement is sufficient to pay such fees.

                  SECTION 3.06. Assumption or Termination of Sub-Servicing
                                Agreements by Trust Administrator.

                  In the event the Master Servicer shall for any reason no
longer be the master servicer (including by reason of the occurrence of a Master
Servicer Event of Default), the Trust Administrator or its designee shall
thereupon assume all of the rights and obligations of the Master Servicer under
each Sub-Servicing Agreement that the Master Servicer may have entered into,
unless the Trust Administrator elects to terminate any Sub-Servicing Agreement
in accordance with its terms as provided in Section 3.03. Upon such assumption,
the Trust Administrator, its designee or the successor servicer for the Trust
Administrator appointed pursuant to Section 7.02 shall be deemed, subject to
Section 3.03, to have assumed all of the Master Servicer's interest therein and
to have replaced the Master Servicer as a party to each Sub-Servicing Agreement
to the same extent as if each Sub-Servicing Agreement had been assigned to the
assuming party, except that (i) the Master Servicer shall not thereby be
relieved of any liability or obligations under any Sub-Servicing Agreement and
(ii) none of the Trust Administrator, its designee or any successor Master
Servicer shall be deemed to have assumed any liability or obligation of the
Master Servicer that arose before it ceased to be the Master Servicer.

                  The Master Servicer at its expense shall, upon request of the
Trust Administrator, deliver to the assuming party all documents and records
relating to each Sub-Servicing Agreement and the Mortgage Loans then being
serviced and an accounting of amounts collected and held by or on behalf of it,
and otherwise use its best efforts to effect the orderly and efficient transfer
of the Sub- Servicing Agreements to the assuming party.

                  SECTION 3.07. Collection of Certain Mortgage Loan Payments.

                  The Master 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 Agreement
and any applicable insurance policies, follow such collection procedures as it
would follow with respect to mortgage loans comparable to the Mortgage Loans and
held for its own account. Consistent with the foregoing, the Master Servicer may
in its discretion (i) waive any late payment charge or, if applicable, penalty
interest or (ii) extend the due dates for Monthly Payments due on a Mortgage
Note for a period of not greater than 180 days; provided that any extension
pursuant to clause (ii) above shall not affect the amortization schedule of any
Mortgage Loan for purposes of any computation hereunder, except as provided
below. In the event of any such arrangement pursuant to clause (ii) above, the
Master Servicer shall make timely advances on such Mortgage Loan during such
extension pursuant to Section 4.03 and in accordance with the amortization
schedule of such Mortgage Loan without modification thereof by reason of such
arrangements. Notwithstanding the foregoing, in the event that any Mortgage Loan
is in default or, in the judgment of the Master Servicer, such default is
reasonably foreseeable, the Master Servicer, consistent with the standards set
forth in Section 3.01, may also accept payment from the related Mortgagor of an
amount less than the Stated Principal Balance in final satisfaction of such
Mortgage Loan (such payment, a "Short Pay-off") or consent to the postponement
of strict

                                       64
<PAGE>

compliance with any such term or otherwise grant indulgence to any Mortgagor. In
addition, in connection with any Curtailment of a Mortgage Loan, the Master
Servicer, to the extent not inconsistent with the terms of the Mortgage Note and
local law and practice, may permit the Mortgage Loan to be re-amortized such
that the Monthly Payment is recalculated as an amount that will fully amortize
the remaining Stated Principal Balance thereof by the original Maturity Date
based on the original Mortgage Rate; provided, that such re-amortization shall
not be permitted if it would constitute a reissuance of the Mortgage Loan for
federal income tax purposes, except if such reissuance is described in Treasury
Regulation Section 1.860G-2(b)(3).

                  SECTION 3.08. Sub-Servicing Accounts.

                  In those cases where a Sub-Servicer is servicing a Mortgage
Loan pursuant to a Sub- Servicing Agreement, the Sub-Servicer will be required
to establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be an Eligible Account and shall
comply with all requirements of this Agreement relating to the Collection
Account. The Sub-Servicer shall deposit in the clearing account (which account
must be an Eligible Account) in which it customarily deposits payments and
collections on mortgage loans in connection with its mortgage loan servicing
activities on a daily basis, and in no event more than two Business Days after
the Sub-Servicer's receipt thereof, all proceeds of Mortgage Loans received by
the Sub- Servicer less its servicing compensation to the extent permitted by the
Sub-Servicing Agreement, and shall thereafter deposit such amounts in the
Sub-Servicing Account, in no event more than one Business Day after the deposit
of such funds into the clearing account. The Sub-Servicer shall thereafter
deposit such proceeds in the Collection Account or remit such proceeds to the
Master Servicer for deposit in the Collection Account not later than two
Business Days after the deposit of such amounts in the Sub-Servicing Account.
For purposes of this Agreement, the Master Servicer shall be deemed to have
received payments on the Mortgage Loans when the Sub-Servicer receives such
payments.

                  SECTION 3.09. Collection of Taxes, Assessments and Similar
                                Items; Servicing Accounts.

                  The Master Servicer may establish and maintain one or more
accounts (the "Servicing Accounts"), into which all collections from the
Mortgagors (or related advances from Sub-Servicers) for the payment of ground
rents, taxes, assessments, fire and hazard insurance premiums, water charges,
sewer rents and comparable items for the account of the Mortgagors ("Escrow
Payments") shall be deposited and retained. Servicing Accounts shall be Eligible
Accounts; provided, however, that Servicing Accounts need only be established
and maintained by the Master Servicer to the extent that it is collecting Escrow
Payments from the Mortgagors. The Master Servicer shall deposit in the clearing
account (which account must be an Eligible Account) in which it customarily
deposits payments and collections on mortgage loans in connection with its
mortgage loan servicing activities on a daily basis, and in no event more than
two Business Days after the Master Servicer's receipt thereof, all Escrow
Payments collected on account of the Mortgage Loans and shall thereafter deposit
such Escrow Payments in the Servicing Accounts, in no event more than one
Business Day after the deposit of such funds in the clearing account, for the
purpose of effecting the payment of any such items as required under the terms
of this Agreement. Withdrawals of amounts from a Servicing Account may be made
only to (i) effect payment of Escrow Payments; (ii) reimburse the Master

                                       65
<PAGE>

Servicer (or a Sub-Servicer to the extent provided in the related Sub-Servicing
Agreement) out of related collections for any advances made pursuant to Section
3.01 (with respect to taxes and assessments) and Section 3.14 (with respect to
hazard insurance); (iii) refund to Mortgagors any sums as may be determined to
be overages; (iv) pay interest, if required and as described below, to
Mortgagors on balances in the Servicing Account; (v) clear and terminate the
Servicing Account at the termination of the Master Servicer's obligations and
responsibilities in respect of the Mortgage Loans under this Agreement in
accordance with Article IX; or (vi) recover amounts deposited in error. As part
of its servicing duties, the Master Servicer or Sub-Servicers shall pay to the
Mortgagors interest on funds in Servicing Accounts, to the extent required by
law and, to the extent that interest earned on funds in the Servicing Accounts
is insufficient, to pay such interest from its or their own funds, without any
reimbursement therefor. To the extent that a Mortgage does not provide for
Escrow Payments, the Master Servicer shall determine whether any such payments
are made by the Mortgagor in a manner and at a time that avoids the loss of the
Mortgaged Property due to a tax sale or the foreclosure of a tax lien. The
Master Servicer assumes full responsibility for the payment of all such bills
and shall effect payments of all such bills irrespective of the Mortgagor's
faithful performance in the payment of same or the making of the Escrow Payments
and shall make advances from its own funds to effect such payments.

                  SECTION 3.10. Collection Account and Distribution Account.

                  (a) On behalf of the Trust Fund, the Master Servicer shall
         establish and maintain one or more accounts (such account or accounts,
         the "Collection Account"), held in trust for the benefit of the Trust
         Administrator, the Trustee and the Certificateholders. On behalf of the
         Trust Fund, the Master Servicer shall deposit or cause to be deposited
         in the clearing account (which account must be an Eligible Account) in
         which it customarily deposits payments and collections on mortgage
         loans in connection with its mortgage loan servicing activities on a
         daily basis, and in no event more than two Business Days after the
         Master Servicer's receipt thereof, and shall thereafter deposit in the
         Collection Account, in no event more than one Business Day after the
         deposit of such funds into the clearing account, as and when received
         or as otherwise required hereunder, the following payments and
         collections received or made by it from and after the Cut-off Date
         (other than in respect of principal or interest on the related Mortgage
         Loans due on or before the Cut-off Date), or payments (other than
         Principal Prepayments) received by it on or prior to the Cut-off Date
         but allocable to a Due Period subsequent thereto:

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

                  (ii) all payments on account of interest (net of the related
         Servicing Fee) on each Mortgage Loan;

                  (iii) all Insurance Proceeds and Liquidation Proceeds (other
         than proceeds collected in respect of any particular REO Property and
         amounts paid by the Master Servicer in connection with a purchase of
         Mortgage Loans and REO Properties pursuant to Section 9.01);

                                       66
<PAGE>

                  (iv) any amounts required to be deposited pursuant to Section
         3.12 in connection with any losses realized on Permitted Investments
         with respect to funds held in the Collection Account;

                  (v) any amounts required to be deposited by the Master
         Servicer pursuant to the second paragraph of Section 3.14(a) in respect
         of any blanket policy deductibles;

                  (vi) all proceeds of any Mortgage Loan repurchased or
         purchased in accordance with Section 2.03 or Section 9.01; and

                  (vii) all amounts required to be deposited in connection with
         shortfalls in principal amount of Qualified Substitute Mortgage Loans
         pursuant to Section 2.03.

                  For purposes of the immediately preceding sentence, the
Cut-off Date with respect to any Qualified Substitute Mortgage Loan shall be
deemed to be the date of substitution.

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

                  (b) On behalf of the Trust Fund, the Trust Administrator, as
agent for the Trustee, shall establish and maintain one or more accounts (such
account or accounts, the "Distribution Account"), held in trust for the benefit
of the Trustee and the Certificateholders. On behalf of the Trust Fund, the
Master Servicer shall deliver to the Trust Administrator in immediately
available funds for deposit in the Distribution Account on or before 3:00 p.m.
New York time (i) on the Master Servicer Remittance Date, that portion of the
Available Distribution Amount (calculated without regard to the references in
clause (2) of the definition thereof to amounts that may be withdrawn from the
Distribution Account) for the related Distribution Date then on deposit in the
Collection Account.

                  (c) Funds in the Collection Account and the Distribution
Account may be invested in Permitted Investments in accordance with the
provisions set forth in Section 3.12. The Master Servicer shall give notice to
the Trustee, the Trust Administrator and the Depositor of the location of the
Collection Account maintained by it when established and prior to any change
thereof. The Trust Administrator shall give notice to the Master Servicer, the
Trustee and the Depositor of the location of the Distribution Account when
established and prior to any change thereof.

                  (d) Funds held in the Collection Account at any time may be
delivered by the Master Servicer to the Trust Administrator for deposit in an
account (which may be the Distribution Account and must satisfy the standards
for the Distribution Account as set forth in the definition thereof) and for all
purposes of this Agreement shall be deemed to be a part of the Collection
Account; provided, however, that the Trust Administrator shall have the sole
authority to withdraw

                                       67
<PAGE>

any funds held pursuant to this subsection (d). In the event the Master Servicer
shall deliver to the Trust Administrator for deposit in the Distribution Account
any amount not required to be deposited therein, it may at any time request that
the Trust Administrator withdraw such amount from the Distribution Account and
remit to it any such amount, any provision herein to the contrary
notwithstanding. In addition, the Master Servicer shall deliver to the Trust
Administrator from time to time for deposit, and upon written notification from
the Master Servicer, the Trust Administrator shall so deposit, in the
Distribution Account:

                  (i) any P&I Advances, as required pursuant to Section 4.03;

                  (ii) any amounts required to be deposited pursuant to Section
         3.23(d) or (f) in connection with any REO Property;

                  (iii) any amounts to be paid by the Master Servicer in
         connection with a purchase of Mortgage Loans and REO Properties
         pursuant to Section 9.01;

                  (iv) any amounts required to be deposited pursuant to Section
         3.24 in connection with any Prepayment Interest Shortfalls; and

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

                  (e) Promptly upon receipt of any Stayed Funds, whether from
         the Master Servicer, a trustee in bankruptcy, or federal bankruptcy
         court or other source, the Trust Administrator shall deposit such funds
         in the Distribution Account, subject to withdrawal thereof pursuant to
         Section 7.02(b) or as otherwise permitted hereunder.

                  (f) The Master Servicer shall deposit in the Collection
         Account any amounts required to be deposited pursuant to Section
         3.12(b) in connection with losses realized on Permitted Investments
         with respect to funds held in the Collection Account.

                  SECTION 3.11. Withdrawals from the Collection Account and
                                Distribution Account.

                  (a) The Master Servicer shall, from time to time, make
withdrawals from the Collection Account for any of the following purposes or as
described in Section 4.03:

                  (i) to remit to the Trust Administrator for deposit in the
         Distribution Account the amounts required to be so remitted pursuant to
         Section 3.10(b) or permitted to be so remitted pursuant to the first
         sentence of Section 3.10(d);

                  (ii) subject to Section 3.16(d), to reimburse the Master
         Servicer for P&I Advances, but only to the extent of amounts received
         which represent Late Collections (net of the related Servicing Fees) of
         Monthly Payments on Mortgage Loans with respect to which such P&I
         Advances were made in accordance with the provisions of Section 4.03;

                                       68
<PAGE>

                  (iii) subject to Section 3.16(d), to pay the Master Servicer
         or any Sub- Servicer (A) any unpaid Servicing Fees, (B) any
         unreimbursed Servicing Advances with respect to each Mortgage Loan, but
         only to the extent of any Liquidation Proceeds, Insurance Proceeds or
         other amounts as may be collected by the Master Servicer from a
         Mortgagor, or otherwise received with respect to such Mortgage Loan and
         (C) any nonrecoverable Servicing Advances following the final
         liquidation of a Mortgage Loan, but only to the extent that Late
         Collections, Liquidation Proceeds and Insurance Proceeds received with
         respect to such Mortgage Loan are insufficient to reimburse the Master
         Servicer or any Sub-Servicer for such Servicing Advances;

                  (iv) to pay to the Master Servicer as servicing compensation
         (in addition to the Servicing Fee) on the Master Servicer Remittance
         Date any interest or investment income earned on funds deposited in the
         Collection Account;

                  (v) to pay to the Master Servicer, the Depositor or the
         Sellers, as the case may be, with respect to each Mortgage Loan that
         has previously been purchased or replaced pursuant to Section 2.03 or
         Section 3.16(c) all amounts received thereon subsequent to the date of
         purchase or substitution, as the case may be;

                  (vi) to reimburse the Master Servicer for any P&I Advance
         previously made which the Master Servicer has determined to be a
         Nonrecoverable P&I Advance in accordance with the provisions of Section
         4.03;

                  (vii) to reimburse the Master Servicer or the Depositor for
         expenses incurred by or reimbursable to the Master Servicer or the
         Depositor, as the case may be, pursuant to Section 6.03;

                  (viii) to reimburse the Master Servicer, the Trust
         Administrator or the Trustee, as the case may be, for expenses
         reasonably incurred in respect of the breach or defect giving rise to
         the purchase obligation under Section 2.03 or Section 2.04 of this
         Agreement that were included in the Purchase Price of the Mortgage
         Loan, including any expenses arising out of the enforcement of the
         purchase obligation;

                  (ix) to pay, or to reimburse the Master Servicer for advances
         in respect of expenses incurred in connection with any Mortgage Loan
         pursuant to Section 3.16(b);

                  (x) [reserved]; and

                  (xi) to clear and terminate the Collection Account pursuant to
         Section 9.01.

                  The Master 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, to the extent held by or
on behalf of it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (viii) and
(ix) above. The Master Servicer shall provide written notification to the
Trustee and the Trust Administrator, on or prior to the next succeeding Master
Servicer Remittance Date, upon making any withdrawals from the Collection
Account pursuant to subclause (vii) above.

                                       69
<PAGE>

                  (b) The Trust Administrator shall, from time to time, make
         withdrawals from the Distribution Account, for any of the following
         purposes, without priority:

                  (i) to make distributions to Certificateholders in accordance
         with Section 4.01;

                  (ii) to pay to itself and the Trustee (if the Trust
         Administrator is not the Master Servicer) amounts to which each is
         entitled pursuant to Section 8.05 and any other Extraordinary Trust
         Fund Expenses;

                  (iii) to pay to the Master Servicer any interest income earned
         on funds deposited in the Distribution Account pursuant to Section
         3.12(c);

                  (iv) to reimburse itself pursuant to Section 7.02;

                  (v) to pay any amounts in respect of taxes pursuant to
         10.01(g)(iii);

                  (vi) [reserved];

                  (vii) to reimburse itself for any P&I Advance made by it under
         Section 7.01 (if not reimbursed by the Master Servicer) to the same
         extent the Master Servicer would be entitled to reimbursement under
         Section 3.11(a); and

                  (viii) to clear and terminate the Distribution Account
         pursuant to Section 9.01.

                  SECTION 3.12. Investment of Funds in the Collection Account
                                and the Distribution Account.

                  (a) The Master Servicer may direct any depository institution
maintaining the Collection Account (for purposes of this Section 3.12, an
"Investment Account"), and the Trust Administrator shall direct any depository
institution maintaining the Distribution Account (for purposes of this Section
3.12, also an "Investment Account"), to invest the funds in such Investment
Account in one or more Permitted Investments specified in such instruction
bearing interest or sold at a discount, and maturing, unless payable on demand,
(i) no later than the Business Day immediately preceding the date on which such
funds are required to be withdrawn from such account pursuant to this Agreement,
if a Person other than the Trust Administrator is the obligor thereon, and (ii)
no later than the date on which such funds are required to be withdrawn from
such account pursuant to this Agreement, if the Trust Administrator is the
obligor thereon. All such Permitted Investments shall be held to maturity,
unless payable on demand. Any investment of funds in an Investment Account shall
be made in the name of the Trust Administrator (in its capacity as such) or in
the name of a nominee of the Trust Administrator. The Trust Administrator shall
be entitled to sole possession (except with respect to investment direction of
funds held in the Collection Account and any income and gain realized thereon)
over each such investment, and any certificate or other instrument evidencing
any such investment shall be delivered directly to the Trust Administrator or
its agent, together with any document of transfer necessary to transfer title to
such investment to the Trust Administrator or its nominee. In the event amounts
on deposit in an

                                       70
<PAGE>

Investment Account are at any time invested in a Permitted Investment payable on
demand, the Trust Administrator shall:

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

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

                  (b) All income and gain realized from the investment of funds
         deposited in the Collection Account held by or on behalf of the Master
         Servicer, shall be for the benefit of the Master Servicer and shall be
         subject to its withdrawal in accordance with Section 3.11. The Master
         Servicer shall deposit in the Collection Account the amount of any loss
         of principal incurred in respect of any such Permitted Investment made
         with funds in such accounts immediately upon realization of such loss.

                  (c) All income and gain realized from the investment of funds
         deposited in the Distribution Account held by or on behalf of the Trust
         Administrator, shall be for the benefit of the Trust Administrator and
         shall be subject to its withdrawal at any time. The Trust Administrator
         shall remit to the Distribution Account the amount of any loss of
         principal incurred in respect of any such Permitted Investment made
         with funds in such accounts immediately upon realization of such loss.

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

                  SECTION 3.13. [Reserved].

                  SECTION 3.14. Maintenance of Hazard Insurance and Errors and
                                Omissions and Fidelity Coverage.

                  (a) The Master Servicer shall cause to be maintained for each
Mortgage Loan (other than a Cooperative Loan) fire insurance with extended
coverage on the related Mortgaged Property in an amount which is at least equal
to the least of (i) the current principal balance of such Mortgage Loan, (ii)
the amount necessary to fully compensate for any damage or loss to the
improvements that are a part of such property on a replacement cost basis and
(iii) the maximum insurable value of the improvements which are a part of such
Mortgaged Property, in each case in an amount not less than such amount as is
necessary to avoid the application of any coinsurance

                                       71
<PAGE>

clause contained in the related hazard insurance policy. The Master Servicer
shall also cause to be maintained fire insurance with extended coverage on each
REO Property (other than REO Properties acquired in respect of Cooperative
Loans) in an amount which is at least equal to the lesser of (i) the maximum
insurable value of the improvements which are a part of such property and (ii)
the outstanding principal balance of the related Mortgage Loan at the time it
became an REO Property, plus accrued interest at the Mortgage Rate and related
Servicing Advances. The Master Servicer will comply in the performance of this
Agreement with all reasonable rules and requirements of each insurer under any
such hazard policies. Any amounts to be collected by the Master Servicer under
any such policies (other than amounts to be applied to the restoration or repair
of the property subject to the related Mortgage or amounts to be released to the
Mortgagor in accordance with the procedures that the Master Servicer would
follow in servicing loans held for its own account, subject to the terms and
conditions of the related Mortgage and Mortgage Note) shall be deposited in the
Collection Account, subject to withdrawal pursuant to Section 3.11, if received
in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal
pursuant to Section 3.23, if received in respect of an REO Property. Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the purpose of calculating distributions to Certificateholders, be added to the
unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit. It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
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 Mortgaged
Property or REO Property is at any time in an area identified in the Federal
Register by the Federal Emergency Management Agency as having special flood
hazards, the Master Servicer will cause to be maintained a flood insurance
policy in respect thereof. Such flood insurance shall be in an amount equal to
the lesser of (i) the unpaid principal balance of the related Mortgage Loan 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).

                  In the event that the Master Servicer shall obtain and
maintain a blanket policy with an insurer having a General Policy Rating of A:X
or better in Best's Key Rating Guide (or such other rating that is comparable to
such rating) 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 two sentences of this Section 3.14, it being understood and agreed
that such policy may contain a deductible clause, in which case the Master
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property or REO Property a policy complying with the first two
sentences of this Section 3.14, and there shall have been one or more losses
which would have been covered by such policy, deposit to the Collection Account
from its own funds the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as
administrator and servicer of the Mortgage Loans, the Master Servicer agrees to
prepare and present, on behalf of itself, the Trustee and the
Certificateholders, claims under any such blanket policy in a timely fashion in
accordance with the terms of such policy.

                  (b) The Master Servicer shall keep in force during the term of
this Agreement a policy or policies of insurance covering errors and omissions
for failure in the performance of the Master Servicer's obligations under this
Agreement, which policy or policies would meet the requirements of Fannie Mae or
Freddie Mac if it were the purchaser of the Mortgage Loans (other

                                       72
<PAGE>

than the amount of the deductible; provided, however, that if Fitch's senior
unsecured debt rating of U.S. Trust Corporation is downgraded below "BBB," the
Master Servicer shall, within 30 days of such downgrade, obtain a policy or
policies of insurance covering errors and omissions for failure in the
performance of the Master Servicer's obligations under this Agreement, which
policy or policies would meet the requirements of Fannie Mae or Freddie Mac if
it were the purchaser of the Mortgage Loans), unless the Master Servicer has
obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The
Master Servicer shall also maintain a fidelity bond that would meet the
requirements of Fannie Mae or Freddie Mac, other than the amount of the
deductible, unless the Master Servicer has obtained a waiver of such
requirements from Fannie Mae or Freddie Mac. The Master Servicer shall provide
the Trustee (upon the Trustee's reasonable request) with copies of any such
insurance policies and fidelity bond. The Master Servicer shall be deemed to
have complied with this provision if an Affiliate of the Master Servicer has
such errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Master Servicer. Any such errors and omissions policy and fidelity bond
shall by its terms not be cancelable without thirty days' prior written notice
to the Trustee and the Trust Administrator. The Master Servicer shall also cause
each Sub-Servicer to maintain a policy of insurance covering errors and
omissions and a fidelity bond which would meet such requirements.

                  SECTION 3.15. Enforcement of Due-On-Sale Clauses; Assumption
                                Agreements.

                  The Master Servicer will, to the extent it has knowledge of
any conveyance or prospective conveyance of any Mortgaged Property by any
Mortgagor (whether by absolute conveyance or by contract of sale, and whether or
not the Mortgagor remains or is to remain liable under the Mortgage Note and/or
the Mortgage), exercise its rights to accelerate the maturity of such Mortgage
Loan under the "due-on-sale" clause, if any, applicable thereto. If the Master
Servicer reasonably believes it is unable under applicable law to enforce such
"due-on-sale" clause, or if any of the other conditions set forth in the proviso
to the preceding sentence apply, the Master Servicer will enter into an
assumption and modification agreement from or with the person to whom such
property has been conveyed or is proposed to be conveyed, pursuant to which such
person becomes liable under the Mortgage Note and, to the extent permitted by
applicable state law, the Mortgagor remains liable thereon. The Master Servicer
is also authorized to enter into a substitution of liability agreement with such
person, pursuant to which the original Mortgagor is released from liability and
such person is substituted as the Mortgagor and becomes liable under the
Mortgage Note, provided that no such substitution shall be effective unless such
person satisfies the underwriting criteria of the Master Servicer. In connection
with any assumption or substitution, the Master Servicer shall apply such
underwriting standards and follow such practices and procedures as shall be
normal and usual in its general mortgage servicing activities and as it applies
to other mortgage loans owned solely by it. The Master Servicer shall not take
or enter into any assumption and modification agreement, however, unless (to the
extent practicable in the circumstances) it shall have received confirmation, in
writing, of the continued effectiveness of any applicable hazard insurance
policy, or a new policy meeting the requirements of this Section is obtained.
Any fee collected by the Master Servicer in respect of an assumption or
substitution of liability agreement will be retained by the Master Servicer as
additional servicing compensation. In connection with any such assumption, no
material term of the Mortgage Note (including but not limited to the related
Mortgage Rate and the amount of the Monthly Payment) may be amended or modified,
except as

                                       73
<PAGE>

otherwise required pursuant to the terms thereof. The Master Servicer shall
notify the Trustee and the Trust Administrator that any such substitution or
assumption agreement has been completed by forwarding to the Trustee (with a
copy to the Trust Administrator) the executed original of such substitution or
assumption agreement, which document shall be added to the related Mortgage File
and shall, for all purposes, be considered a part of such Mortgage File to the
same extent as all other documents and instruments constituting a part thereof.

                  Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Master Servicer shall not be deemed to be in default,
breach or any other violation of its obligations hereunder by reason of any
assumption of a Mortgage Loan by operation of law or by the terms of the
Mortgage Note or any assumption which the Master Servicer may be restricted by
law from preventing, for any reason whatever. For purposes of this Section 3.15,
the term "assumption" is deemed to also include a sale (of the Mortgaged
Property) subject to the Mortgage that is not accompanied by an assumption or
substitution of liability agreement.

                  SECTION 3.16. Realization Upon Defaulted Mortgage Loans.

                  (a) The Master Servicer shall, consistent with the servicing
standard set forth in Section 3.01, foreclose upon or otherwise comparably
convert the ownership of properties 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 pursuant to Section 3.07. The Master
Servicer shall be responsible for all costs and expenses incurred by it in any
such proceedings; provided, however, that such costs and expenses will be
recoverable as Servicing Advances by the Master Servicer as contemplated in
Section 3.11 and Section 3.23. The foregoing is subject to the provision that,
in any case in which Mortgaged Property shall have suffered damage from an
Uninsured Cause, the Master Servicer shall not be required to expend its own
funds toward the restoration of such property unless it shall determine in its
discretion that such restoration will increase the proceeds of liquidation of
the related Mortgage Loan after reimbursement to itself for such expenses.

                  (b) Notwithstanding the foregoing provisions of this Section
3.16 or any other provision of this Agreement, with respect to any Mortgage Loan
as to which the Master Servicer has received actual notice of, or has actual
knowledge of, the presence of any toxic or hazardous substance on the related
Mortgaged Property, the Master Servicer shall not, on behalf of the Trustee,
either (i) obtain title to such Mortgaged Property as a result of or in lieu of
foreclosure or otherwise, or (ii) otherwise acquire possession of, or take any
other action with respect to, such Mortgaged Property, if, as a result of any
such action, the Trustee, the Trust Fund, the Trust Administrator, the Master
Servicer or the Certificateholders would be considered to hold title to, to be a
"mortgagee-in- possession" of, or to be an "owner" or "operator" of such
Mortgaged Property within the meaning of the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended from time to time,
or any comparable law, unless the Master Servicer has also previously
determined, based on its reasonable judgment and a report prepared by a Person
who regularly conducts environmental audits using customary industry standards,
that:

                                       74
<PAGE>

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

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

                  The cost of the environmental audit report contemplated by
this Section 3.23 shall be advanced by the Master Servicer, subject to the
Master Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.11(a)(ix), such right of reimbursement being prior to the
rights of Certificateholders to receive any amount in the Collection Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

                  If the Master Servicer determines, as described above, that it
is in the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Master Servicer shall take such action as it deems to be in the best
economic interest of the Trust Fund. The cost of any such compliance,
containment, cleanup or remediation shall be advanced by the Master Servicer,
subject to the Master Servicer's right to be reimbursed therefor from the
Collection Account as provided in Section 3.11(a)(ix), such right of
reimbursement being prior to the rights of Certificateholders to receive any
amount in the Collection Account received in respect of the affected Mortgage
Loan or other Mortgage Loans.

                  (c) [Reserved].

                  (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan,
will be applied in the following order of priority: first, to reimburse the
Master Servicer or any Sub-Servicer for any related unreimbursed Servicing
Advances and P&I Advances, pursuant to Section 3.11(a)(ii) or (a)(iii)(B);
second, to accrued and unpaid interest on the Mortgage Loan, to the date of the
Final Recovery Determination, or to the Due Date prior to the Distribution Date
on which such amounts are to be distributed if not in connection with a Final
Recovery Determination; and third, as a recovery of principal of the Mortgage
Loan. If the amount of the recovery so allocated to interest is less than the
full amount of accrued and unpaid interest due on such Mortgage Loan, the amount
of such recovery will be allocated by the Master Servicer as follows: first, to
unpaid Servicing Fees; and second, to the balance of the interest then due and
owing. The portion of the recovery so allocated to unpaid Servicing Fees shall
be reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section
3.11(a)(iii)(A).

                                       75
<PAGE>

                  SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files.

                  (a) Upon the payment in full of any Mortgage Loan, or the
receipt by the Master Servicer of a notification that payment in full shall be
escrowed in a manner customary for such purposes, the Master Servicer will
immediately notify the Trustee by a certification in the form of Exhibit E-2
(which certification shall include a statement to the effect that all amounts
received or to be received in connection with such payment which are required to
be deposited in the Collection Account pursuant to Section 3.10 have been or
will be so deposited) of a Servicing Officer and shall request delivery to it of
the Mortgage File. Upon receipt of such certification and request, the Trustee
shall promptly release the related Mortgage File to the Master Servicer. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account or the Distribution
Account.

                  The Trustee shall, at the written request and expense of any
Certificateholder, provide a written report to such Certificateholder of all
Mortgage Files released to the Master Servicer for servicing purposes.

                  (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Trustee shall, upon
request of the Master Servicer and delivery to the Trustee of a Request for
Release in the form of Exhibit E-l, release the related Mortgage File to the
Master Servicer, and the Trustee shall, at the direction of the Master Servicer,
execute such documents as shall be necessary to the prosecution of any such
proceedings. Such Request for Release shall obligate the Master Servicer to
return each and every document previously requested from the Mortgage File to
the Trustee when the need therefor by the Master Servicer no longer exists,
unless the Mortgage Loan has been liquidated and the Liquidation Proceeds
relating to the Mortgage Loan have been deposited in the Collection Account or
the Mortgage File or such document has been delivered to an attorney, or to a
public trustee or other public official as required by law, for purposes of
initiating or pursuing legal action or other proceedings for the foreclosure of
the Mortgaged Property either judicially or non-judicially, and the Master
Servicer has delivered to the Trustee a certificate of a Servicing Officer
certifying as to the name and address of the Person to which such Mortgage File
or such document was delivered and the purpose or purposes of such delivery.
Upon receipt of a certificate of a Servicing Officer stating that such Mortgage
Loan was liquidated and that all amounts received or to be received in
connection with such liquidation that are required to be deposited into the
Collection Account have been so deposited, or that such Mortgage Loan has become
an REO Property, a copy of the Request for Release shall be released by the
Trustee to the Master Servicer.

                  (c) Upon written certification of a Servicing Officer, the
Trustee shall execute and deliver to the Master Servicer any court pleadings,
requests for trustee's sale or other documents reasonably necessary to the
foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal
action brought to obtain judgment against any Mortgagor on the Mortgage Note or
Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or
rights provided by the Mortgage Note or Mortgage or otherwise available at law
or in equity. Each such certification shall include a request that such
pleadings or documents be executed by the Trustee and a statement as to the
reason such documents or pleadings are required and that the execution and
delivery thereof

                                       76
<PAGE>

by the Trustee will not invalidate or otherwise affect the lien of the Mortgage,
except for the termination of such a lien upon completion of the foreclosure or
trustee's sale.

                  SECTION 3.18. Servicing Compensation.

                  As compensation for the activities of the Master Servicer
hereunder, the Master Servicer shall be entitled to the Servicing Fee with
respect to each Mortgage Loan payable solely from payments of interest in
respect of such Mortgage Loan, subject to Section 3.24. In addition, the Master
Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance
Proceeds or Liquidation Proceeds to the extent permitted by Section
3.11(a)(iii)(A) and out of amounts derived from the operation and sale of an REO
Property to the extent permitted by Section 3.23. The right to receive the
Servicing Fee may not be transferred in whole or in part except in connection
with the transfer of all of the Master Servicer's responsibilities and
obligations under this Agreement.

                  Additional servicing compensation in the form of assumption
fees, late payment charges, prepayment charges and other similar fees and
charges shall be retained by the Master Servicer (subject to Section 3.24) only
to the extent such fees or charges are received by the Master Servicer. The
Master Servicer shall also be entitled pursuant to Section 3.11(a)(iv) to
withdraw from the Collection Account, and pursuant to Section 3.23(b) to
withdraw from any REO Account, as additional servicing compensation, interest or
other income earned on deposits therein, subject to Section 3.12 and Section
3.24. The Master Servicer shall be required to pay all expenses incurred by it
in connection with its servicing activities hereunder (including premiums for
the insurance required by Section 3.14, to the extent such premiums are not paid
by the related Mortgagors or by a Sub-Servicer, servicing compensation of each
Sub-Servicer, and to the extent provided herein in Section 8.05, the fees and
expenses of the Trustee and the Trust Administrator) and shall not be entitled
to reimbursement therefor except as specifically provided herein.

                  SECTION 3.19. Reports to the Trustee and the Trust
                                Administrator; Collection Account Statements.

                  Not later than fifteen days after each Distribution Date, the
Master Servicer shall forward to the Trust Administrator, upon the request of
the Trust Administrator, a statement prepared by the Master Servicer setting
forth the status of the Collection Account as of the close of business on the
last day of the calendar month relating to such Distribution Date and showing,
for the period covered by such statement, the aggregate amount of deposits into
and withdrawals from the Collection Account of each category of deposit
specified in Section 3.10(a) and each category of withdrawal specified in
Section 3.11. Such statement may be in the form of the then current Fannie Mae
Monthly Accounting Report for its Guaranteed Mortgage Pass-Through Program with
appropriate additions and changes, and shall also include information as to the
aggregate of the outstanding principal balances of all of the Mortgage Loans as
of the last day of the calendar month immediately preceding such Distribution
Date. Copies of such statement shall be provided by the Trust Administrator to
any Certificateholder and to any Person identified to the Trust Administrator as
a prospective transferee of a Certificate, upon the request and at the expense
of the requesting party, provided such statement is delivered by the Master
Servicer to the Trust Administrator.

                  SECTION 3.20. Statement as to Compliance.

                                       77
<PAGE>

                  On or before March 15th of each calendar year commencing in
2004, the Master Servicer will deliver to the Trust Administrator, the Trustee,
the Depositor and the Rating Agency, an Officers' Certificate (in the form
attached hereto as Exhibit I) stating, as to each signatory thereof, that (i) a
review of the activities of the Master Servicer during the preceding year and of
performance under this Agreement has been made under such officers' supervision
and (ii) to the best of such officers' knowledge, based on such review, the
Master Servicer has fulfilled all of its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the
nature and status thereof. Copies of any such statement shall be provided by the
Trust Administrator to any Certificateholder and to any Person identified to the
Trust Administrator as a prospective transferee of a Certificate, upon the
request and at the expense of the requesting party, provided that such statement
is delivered by the Master Servicer to the Trust Administrator.

                  SECTION 3.21. Independent Public Accountants' Servicing
                                Report.

                  Not later than March 15th of each calendar year commencing in
2004, the Master Servicer, at its expense, shall cause a nationally recognized
firm of independent certified public accountants to furnish to the Master
Servicer a report stating that (i) it has obtained a letter of representation
regarding certain matters from the management of the Master Servicer which
includes an assertion that the Master Servicer has complied with certain minimum
residential mortgage loan servicing standards, identified in the Uniform Single
Attestation Program for Mortgage Bankers established by the Mortgage Bankers
Association of America, with respect to the servicing of residential mortgage
loans during the most recently completed fiscal year and (ii) on the basis of an
examination conducted by such firm in accordance with standards established by
the American Institute of Certified Public Accountants, such representation is
fairly stated in all material respects, subject to such exceptions and other
qualifications that may be appropriate. In rendering its report such firm may
rely, as to matters relating to the direct servicing of residential mortgage
loans by Sub- Servicers, upon comparable reports of firms of independent
certified public accountants rendered on the basis of examinations conducted in
accordance with the same standards (rendered within one year of such report)
with respect to those Sub-Servicers. Immediately upon receipt of such report,
the Master Servicer shall furnish a copy of such report to the Trustee, the
Trust Administrator and the Rating Agencies. Copies of such statement shall be
provided by the Trust Administrator to any Certificateholder upon request at the
Master Servicer's expense, provided that such statement is delivered by the
Master Servicer to the Trust Administrator. In the event such firm of
independent certified public accountants requires the Trust Administrator to
agree to the procedures performed by such firm, the Master Servicer shall direct
the Trust Administrator in writing to so agree; it being understood and agreed
that the Trust Administrator will deliver such letter of agreement in conclusive
reliance upon the direction of the Master Servicer, and the Trust Administrator
has not made any independent inquiry or investigation as to, and shall have no
obligation or liability in respect of, the sufficiency, validity or correctness
of such procedures.

                  SECTION 3.22. Access to Certain Documentation.

                  The Master Servicer shall provide to the Office of the
Controller of the Currency, the Office of Thrift Supervision, the FDIC, and any
other federal or state banking or insurance regulatory authority that may
exercise authority over any Certificateholder, access to the documentation

                                       78
<PAGE>

regarding the Mortgage Loans required by applicable laws and regulations. Such
access shall be afforded without charge, but only upon reasonable request and
during normal business hours at the offices of the Master Servicer designated by
it. In addition, access to the documentation regarding the Mortgage Loans
required by applicable laws and regulations will be provided to such
Certificateholder, the Trustee, the Trust Administrator and to any Person
identified to the Master Servicer as a prospective transferee of a Certificate,
upon reasonable request during normal business hours at the offices of the
Master Servicer designated by it at the expense of the Person requesting such
access.

                  SECTION 3.23. Title, Management and Disposition of REO
                                Property.

                  (a) The deed or certificate of sale of any REO Property shall
be taken in the name of the Trustee, or its nominee, in trust for the benefit of
the Certificateholders. The Master Servicer, on behalf of the Trust Fund and
consistent with the servicing standard set forth in Section 3.01, shall either
sell any REO Property before the close of the third taxable year following the
year the Trust Fund acquires ownership of such REO Property for purposes of
Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no
later than 60 days before the day on which the three- year grace period would
otherwise expire, an extension of the three-year grace period, unless the Master
Servicer shall have delivered to the Trustee, the Trust Administrator and the
Depositor an Opinion of Counsel, addressed to the Trustee, the Trust
Administrator and the Depositor, to the effect that the holding by the Trust
Fund of such REO Property subsequent to three years after its acquisition will
not result in the imposition on any Trust REMIC of taxes on "prohibited
transactions" thereof, as defined in Section 860F of the Code, or cause any
Trust REMIC to fail to qualify as a REMIC under Federal law at any time that any
Certificates are outstanding. The Master Servicer shall, consistent with the
servicing standard set forth in Section 3.01, manage, conserve, protect and
operate each REO Property for the Certificateholders solely for the purpose of
its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC of
any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions.

                  (b) The Master Servicer shall segregate and hold all funds
collected and received in connection with the operation of any REO Property
separate and apart from its own funds and general assets and shall establish and
maintain with respect to REO Properties an account held in trust for the Trustee
for the benefit of the Certificateholders (the "REO Account"), which shall be an
Eligible Account. The Master Servicer shall be permitted to allow the Collection
Account to serve as the REO Account, subject to separate ledgers for each REO
Property. The Master Servicer shall be entitled to retain or withdraw any
interest income paid on funds deposited in the REO Account.

                  (c) The Master Servicer shall have full power and authority,
subject only to the servicing standard set forth in Section 3.01 and the
specific requirements and prohibitions of this Agreement, to do any and all
things in connection with any REO Property as are consistent with the manner in
which the Master Servicer manages and operates similar property owned by the
Master Servicer or any of its Affiliates, all on such terms and for such period
as the Master Servicer deems

                                       79
<PAGE>

to be in the best interests of Certificateholders. In connection therewith, the
Master Servicer shall deposit, or cause to be deposited in the clearing account
(which account must be an Eligible Account) in which it customarily deposits
payments and collections on mortgage loans in connection with its mortgage loan
servicing activities on a daily basis, and in no event more than two Business
Days after the Master Servicer's receipt thereof, and shall thereafter deposit
in the REO Account, in no event more than one Business Day after the deposit of
such funds into the clearing account, all revenues received by it with respect
to an REO Property and shall withdraw therefrom funds necessary for the proper
operation, management and maintenance of such REO Property including, without
limitation:

                  (i) all insurance premiums due and payable in respect of such
         REO Property;

                  (ii) all real estate taxes and assessments in respect of such
         REO Property that may result in the imposition of a lien thereon; and

                  (iii) all costs and expenses necessary to maintain such REO
         Property.

                  To the extent that amounts on deposit in the REO Account with
respect to an REO Property are insufficient for the purposes set forth in
clauses (i) through (iii) above with respect to such REO Property, the Master
Servicer shall, consistent with the servicing standard set forth in Section
3.01, advance from its own funds such amount as is necessary for such purposes
if, but only if, the Master Servicer would make such advances if the Master
Servicer owned the REO Property and if in the Master Servicer's judgment, the
payment of such amounts will be recoverable from the rental or sale of the REO
Property.

                  Notwithstanding the foregoing, none of the Master Servicer or
the Trustee shall:

                  (i) authorize the Trust Fund to enter into, renew or extend
         any New Lease with respect to any REO Property, if the New Lease by its
         terms will give rise to any income that does not constitute Rents from
         Real Property;

                  (ii) authorize any amount to be received or accrued under any
         New Lease other than amounts that will constitute Rents from Real
         Property;

                  (iii) authorize any construction on any REO Property, other
         than the completion of a building or other improvement thereon, and
         then only if more than ten percent of the construction of such building
         or other improvement was completed before default on the related
         Mortgage Loan became imminent, all within the meaning of Section
         856(e)(4)(B) of the Code; or

                  (iv) authorize any Person to Directly Operate any REO Property
         on any date more than 90 days after its date of acquisition by the
         Trust Fund; unless, in any such case, the Master Servicer has obtained
         an Opinion of Counsel, provided to the Trustee and the Trust
         Administrator, to the effect that such action will not cause such REO
         Property to fail to qualify as "foreclosure property" within the
         meaning of Section 860G(a)(8) of the Code at

                                       80
<PAGE>

         any time that it is held by the Trust Fund, in which case the Master
         Servicer may take such actions as are specified in such Opinion of
         Counsel.

                  The Master Servicer may contract with any Independent
Contractor for the operation and management of any REO Property, provided that:

                  (i) the terms and conditions of any such contract shall not be
         inconsistent herewith;

                  (ii) any such contract shall require, or shall be administered
         to require, that the Independent Contractor pay all costs and expenses
         incurred in connection with the operation and management of such REO
         Property, including those listed above and remit all related revenues
         (net of such costs and expenses) to the Master Servicer as soon as
         practicable, but in no event later than thirty days following the
         receipt thereof by such Independent Contractor;

                  (iii) none of the provisions of this Section 3.23(c) relating
         to any such contract or to actions taken through any such Independent
         Contractor shall be deemed to relieve the Master Servicer of any of its
         duties and obligations to the Trustee on behalf of the
         Certificateholders with respect to the operation and management of any
         such REO Property; and

                  (iv) the Master Servicer shall be obligated with respect
         thereto to the same extent as if it alone were performing all duties
         and obligations in connection with the operation and management of such
         REO Property.

                  The Master Servicer shall be entitled to enter into any
agreement with any Independent Contractor performing services for it related to
its duties and obligations hereunder for indemnification of the Master Servicer
by such Independent Contractor, and nothing in this Agreement shall be deemed to
limit or modify such indemnification. The Master Servicer shall be solely liable
for all fees owed by it to any such Independent Contractor, irrespective of
whether the Master Servicer's compensation pursuant to Section 3.18 is
sufficient to pay such fees.

                  (d) In addition to the withdrawals permitted under Section
3.23(c), the Master Servicer may from time to time make withdrawals from the REO
Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid
Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse
itself or any Sub-Servicer for unreimbursed Servicing Advances and P&I Advances
made in respect of such REO Property or the related Mortgage Loan. Any income
from the related REO Property received during any calendar months prior to a
Final Recovery Determination, net of any withdrawals made pursuant to Section
3.23(c) or this Section 3.23(d), shall be withdrawn by the Master Servicer from
each REO Account maintained by it and deposited into the Distribution Account in
accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date
relating to a Final Recovery Determination with respect to such Mortgage Loan,
for distribution on the related Distribution Date in accordance with Section
4.01.

3.23(a) and consistent with the servicing standard set forth in Section 3.01,
each REO Disposition shall be carried out by the Master Servicer at such price
and upon such terms and conditions as the Master Servicer shall deem necessary
or advisable, as shall be normal and usual in its general servicing activities
for similar properties.

                  (f) The proceeds from the REO Disposition, net of any amount
required by law to be remitted to the Mortgagor under the related Mortgage Loan
and net of any payment or reimbursement to the Master Servicer or any
Sub-Servicer as provided above, shall be deposited in the Distribution Account
in accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date in
the month following the receipt thereof for distribution on the related
Distribution Date in accordance with Section 4.01. Any REO Disposition shall be

                  (g) The Master Servicer shall file information returns with
respect to the receipt of mortgage interest received in a trade or business,
reports of foreclosures and abandonments of any Mortgaged Property and
cancellation of indebtedness income with respect to any Mortgaged Property as
required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such

                  The Master Servicer shall deliver to the Trust Administrator
for deposit into the Distribution Account on or before 3:00 p.m. New York time

                  In the event that a shortfall in any collection on or
liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Stated Principal Balances that were made by the Master Servicer
in a manner not consistent with the terms of the related Mortgage Note and this
Agreement, the Master Servicer, upon discovery or receipt of notice thereof,
immediately shall deliver to the Trust Administrator for deposit in the
Distribution Account from its own funds the amount of any such shortfall and
shall indemnify and hold harmless the Trust Fund, the Trustee, the Trust
Administrator, the Depositor and any successor master servicer in respect of any
such liability. Such indemnities shall survive the termination or discharge of
this Agreement.

                  (iv) to distributions of interest in respect of the

         in an amount (allocable among such Certificates PRO RATA in accordance

                  (b)(i) On each Distribution Date, the aggregate distributions
of principal made on such date in respect of the Subordinate Certificates
pursuant to Section 4.01(a)(1)(vii) above shall be applied among the various
Classes thereof, in the order of priority from the Class of Subordinate
Certificates with the lowest numerical designation to the Class of Subordinate
Certificates with the highest numerical designation, in each case to the extent
of remaining available funds up to the amount allocable to such Class for such
Distribution Date and in each case until the aggregate Certificate Principal
Balance of each such Class is reduced to zero, in an amount with respect to each
such Class equal to the sum of (X) the related Class B Percentage of the amounts

such Class pursuant to this Section 4.01(b)(i) for the immediately preceding
Distribution Date, over the aggregate distributions of principal made in respect
of such Class of Certificates on such immediately preceding Distribution Date
pursuant to Section 4.01 to the extent that any such excess is not attributable
to Realized Losses which were allocated to Subordinate Certificates with a lower
priority pursuant to Section 4.04.

                  (ii) On any Distribution Date, the portion of (a) all net
Liquidation Proceeds and Insurance Proceeds with respect to any Mortgage Loans

Classes of Subordinate Certificates (each, an "Eligible Class") in proportion to
the respective outstanding Certificate Principal Balances thereof: (i) the Class
B-1 Certificates, (ii) the Class B-2 Certificates, if on such Distribution Date
the aggregate percentage interest in the Trust Fund evidenced by the Class B-2
Certificates, the Class B-3 Certificates, the Class B-4 Certificates, the Class
B-5 Certificates and the Class B-6 Certificates equals or exceeds 1.25% before
giving effect to distributions on such Distribution Date, (iii) the Class B-3
Certificates, if on such Distribution Date the aggregate percentage interest in

or exceeds 0.50% before giving effect to distributions on such Distribution
Date, (v) the Class B-5 Certificates, if on such Distribution Date the aggregate

<PAGE>

Class B-6 Certificates equals or exceeds 0.30% before giving effect to
distributions on such Distribution Date and (vi) the Class B-6 Certificates, if
on such Distribution Date the percentage interest in the Trust Fund evidenced by
the Class B-6 Certificates equals or exceeds 0.20% before giving effect to
distributions on such Distribution Date. Notwithstanding the foregoing, if the
application of the foregoing on any Distribution Date as provided in Section
4.01 would result in a distribution in respect of principal to any Class or
Classes of Subordinate Certificates in an amount greater than the remaining
Certificate Principal Balance thereof (any such Class, a "Maturing Class") then:
(a) the amount to be allocated to each Maturing Class shall be reduced to a
level that, when applied as described above, would exactly reduce the
Certificate Principal Balance of such Class to zero and (b) the total amount of
the reductions pursuant to clause (a) above in the amount to be allocated to the
Maturing Class or Classes shall be allocated among the remaining Eligible
Classes on a PRO RATA basis in proportion to the respective outstanding
Certificate Principal Balances thereof prior to the allocation thereto of any of
the amounts described in the preceding sentence. Furthermore, if a Class of
Class B Certificates is not an Eligible Class, any amounts allocable to
principal and distributable pursuant to this Section 4.01(b)(ii) will be
distributed among the Class B Certificates that are Eligible Classes in the
manner set forth above.

                  (c) All distributions made with respect to each Class of
Certificates on each Distribution Date shall be allocated PRO RATA among the
outstanding Certificates in such Class based on their respective Percentage
Interests. Payments in respect of each Class of Certificates on each
Distribution Date will be made to the Holders of the respective Class of record
on the related Record Date (except as otherwise provided in Section 4.01(e) or
Section 9.01 respecting the final distribution on such Class), based on the
aggregate Percentage Interest represented by their respective Certificates, and
shall be made by wire transfer of immediately available funds to the account of
any such Holder at a bank or other entity having appropriate facilities
therefor, if such Holder shall have so notified the Trust Administrator in
writing at least five Business Days prior to the Record Date immediately prior
to such Distribution Date and with respect to any Class of Certificates other
than the Residual Certificates is the registered owner of Certificates having an
initial aggregate Certificate Principal Balance that is in excess of the lesser
of (i) $5,000,000 or (ii) two-thirds of the initial Certificate Principal
Balance of such Class of Certificates, or otherwise by check mailed by first
class mail to the address of such Holder appearing in the Certificate Register.
The final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the Corporate Trust Office
or such other location specified in the notice to Certificateholders of such
final distribution.

                  Each distribution with respect to a Book-Entry Certificate
shall be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the Trust
Administrator, the Depositor or the Master Servicer shall have any
responsibility therefor except as otherwise provided by this Agreement or
applicable law.

                  (d) The rights of the Certificateholders to receive
         distributions in respect of the Certificates, and all interests of the
         Certificateholders in such distributions, shall be as set forth in this
         Agreement. None of the Holders of any Class of Certificates, the Trust
         Administrator, the Trustee or the Master Servicer shall in any way be
         responsible or liable to the Holders of any other Class of Certificates
         in respect of amounts properly previously distributed on the
         Certificates.

                  (e) Except as otherwise provided in Section 9.01, whenever the
         Trust Administrator expects that the final distribution with respect to
         any Class of Certificates will be made on the next Distribution Date,
         the Trust Administrator shall, no later than five days after the
         related Determination Date, mail on such date to each Holder of such
         Class of Certificates a notice to the effect that:

                  (i) the Trust Administrator expects that the final
         distribution with respect to such Class of Certificates will be made on
         such Distribution Date, but only upon presentation and surrender of
         such Certificates at the office of the Trust Administrator therein
         specified, and

                  (ii) no interest shall accrue on such Certificates from and
         after the end of the related Interest Accrual Period.

                  Any funds not distributed to any Holder or Holders of
Certificates of such Class on such Distribution Date because of the failure of
such Holder or Holders to tender their Certificates shall, on such date, be set
aside and held in trust by the Trust Administrator and credited to the account
of the appropriate non-tendering Holder or Holders. If any Certificates as to
which notice has been given pursuant to this Section 4.01(e) shall not have been
surrendered for cancellation within six months after the time specified in such
notice, the Trust Administrator shall mail a second notice to the remaining
non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Certificates shall not have
been surrendered for cancellation, the Trust Administrator shall, directly or
through an agent, mail a final notice to remaining non-tendering
Certificateholders concerning surrender of their Certificates and shall continue
to hold any remaining funds for the benefit of non-tendering Certificateholders.
The costs and expenses of maintaining the funds in trust and of contacting such
Certificateholders shall be paid out of the assets remaining in such trust fund.
If within one year after the final notice any such Certificates shall not have
been surrendered for cancellation, the Trust Administrator shall pay to the
Class R Certificateholders all such amounts, and all rights of non-tendering
Certificateholders in or to such amounts shall thereupon cease. No interest
shall accrue or be payable to any Certificateholder on any amount held in trust
by the Trust Administrator as a result of such Certificateholder's failure to
surrender its Certificate(s) for final payment thereof in accordance with this
Section 4.01(e).

                  SECTION 4.02. Statements to Certificateholders.

                  Within a reasonable period of time after the end of each
calendar year, the Trust Administrator shall forward to each Person who at any
time during the calendar year was a Holder of a Regular Certificate a statement
containing the information set forth in subclauses (i) through (iii) above,
aggregated for such calendar year or applicable portion thereof during which
such person was a Certificateholder. Such obligation of the Trust Administrator
shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Trust Administrator pursuant to
any requirements of the Code as from time to time are in force.

                  Within a reasonable period of time after the end of each

time during the calendar year was a Holder of a Residual Certificate a statement
setting forth the amount, if any, actually distributed with respect to the
Residual Certificates, as appropriate, aggregated for such calendar year or

Such obligation of the Trust Administrator shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
prepared by the Trust Administrator and furnished to such Holders pursuant to
the rules and regulations of the Code as are in force from time to time.

                  Upon request, the Trust Administrator shall forward to each
Certificateholder, during the term of this Agreement, such periodic, special, or
other reports or information, whether or not provided for herein, as shall be
reasonable with respect to the Certificateholder, or otherwise with respect to
the purposes of this Agreement, all such reports or information to be provided
at the expense of the Certificateholder in accordance with such reasonable and

the extent that the Trust Administrator receives timely reports as required from
the Master Servicer and the Trustee's duties are limited to the extent that the
Trustee receives timely reports as required from the Trust Administrator.

<PAGE>

Advances to be made by the Master Servicer in respect of the related
Distribution Date, the aggregate amount of P&I Advances outstanding after giving
effect to such P&I Advances, and the aggregate amount of Nonrecoverable P&I
Advances in respect of such Distribution Date and (ii) such other information
with respect to the Mortgage Loans as the Trust Administrator may reasonably
require to perform the calculations necessary to make the distributions
contemplated by Section 4.01 and to prepare the statements to Certificateholders
contemplated by Section 4.02; provided, however, that if the Master Servicer is
not the Trust Administrator, the Master Servicer will forward to the successor
trust administrator the information set forth in clause (i) above on the next
Business Day following the related Determination Date and the information set
forth in clause (ii) above on the fifth Business Day following the last day of
the related calendar month. The Trustee and the Trust Administrator shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Master Servicer.

                  (b) The amount of P&I Advances to be made by the Master
Servicer for any Distribution Date shall equal, subject to Section 4.03(d), the
sum of (i) the aggregate amount of Monthly Payments (with each interest portion
thereof net of the related Servicing Fee), due on the related Due Date in
respect of the Mortgage Loans (other than with respect to any Balloon Loan with
a delinquent Balloon Payment as described in clause (iii) below), which Monthly
Payments were delinquent as of the close of business on the related
Determination Date and (ii) with respect to each REO Property (other than with
respect to any REO Property relating to a Balloon Loan with a delinquent Balloon
Payment as described in clause (iv) below), which REO Property was acquired
during or prior to the related Due Period and as to which REO Property an REO
Disposition did not occur during the related Due Period, an amount equal to the
excess, if any, of the REO Imputed Interest on such REO Property for the most
recently ended calendar month, over the net income from such REO Property
transferred to the Distribution Account pursuant to Section 3.23 for
distribution on such Distribution Date plus (iii) with respect to each Balloon
Loan with a delinquent Balloon Payment, an amount equal to the assumed monthly
principal and interest payment (with each interest portion thereof net of the
related Servicing Fee) that would have been due on the related Due Date based on
the original principal amortization schedule for such Balloon Loan assuming such
Mortgage Loan was not a Balloon Loan, plus (iv) with respect to each REO
Property relating to a Balloon Loan with a delinquent Balloon Payment, which REO
Property was acquired during or prior to the related Prepayment Period and as to
which REO Property an REO Disposition did not occur during the related
Prepayment Period, an amount equal to the excess, if any, of the assumed monthly
principal and interest payment (with each interest portion thereof net of the
related Servicing Fee) that would have been due on the related Due Date based on
the original principal amortization schedule for the related Balloon Loan
assuming such Mortgage Loan was not a Balloon Loan, over the net income from
such REO Property transferred to the Distribution Account pursuant to Section
3.23 for distribution on such Distribution Date.

                  On or before 3:00 p.m. New York time on the Master Servicer
Remittance Date, the Master Servicer shall remit in immediately available funds
to the Trust Administrator for deposit in the Distribution Account an amount
equal to the aggregate amount of P&I Advances, if any, to be made in respect of
the Mortgage Loans and REO Properties for the related Distribution Date either
(i) from its own funds or (ii) from the Collection Account, to the extent of
funds held therein for future distribution (in which case, it will cause to be
made an appropriate entry in the records of Collection Account that amounts held
for future distribution have been, as permitted by this Section

                                       90

4.03, used by the Master Servicer in discharge of any such P&I Advance) or (iii)
in the form of any combination of (i) and (ii) aggregating the total amount of
P&I Advances to be made by the Master Servicer with respect to the Mortgage
Loans and REO Properties. Any amounts held for future distribution and so used
shall be appropriately reflected in the Master Servicer's records and replaced
by the Master Servicer by deposit in the Collection Account on or before any
future Master Servicer Remittance Date to the extent that the Available
Distribution Amount for the related Distribution Date (determined without regard
to P&I Advances to be made on the Master Servicer Remittance Date) shall be less
than the total amount that would be distributed to the Classes of
Certificateholders pursuant to Section 4.01 on such Distribution Date if such
amounts held for future distributions had not been so used to make P&I Advances.
The Trust Administrator will provide notice to the Master Servicer by telecopy
by the close of business on the Master Servicer Remittance Date in the event
that the amount remitted by the Master Servicer to the Trust Administrator on
such Master Servicer Remittance Date is less than the P&I Advances required to
be made by the Master Servicer for the related Distribution Date.

                  (c) The obligation of the Master Servicer to make such P&I
Advances is mandatory, notwithstanding any other provision of this Agreement but
subject to (d) below, and, with respect to any Mortgage Loan or REO Property,
shall continue until a Final Recovery Determination in connection therewith or
the removal thereof from REMIC I pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section.

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

                  SECTION 4.04. Allocation of Extraordinary Trust Fund Expenses
                                and Realized Losses.

                  (a) Prior to each Distribution Date, the Master Servicer shall
determine as to each Mortgage Loan and REO Property: (i) the total amount of
Realized Losses, if any, incurred in connection with any Final Recovery
Determinations made during the related Prepayment Period; (ii) whether and the
extent to which such Realized Losses constituted Fraud Losses or Special Hazard
Losses; and (iii) the respective portions of such Realized Losses allocable to
interest and allocable to principal. Prior to each Distribution Date, the Master
Servicer shall also determine as to each Mortgage Loan: (A) the total amount of
Realized Losses, if any, incurred in connection with any Deficient Valuations
made during the related Prepayment Period; and (B) the total amount of Realized
Losses, if any, incurred in connection with Debt Service Reductions in respect
of Monthly Payments due during the related Due Period. The information described
in the two preceding sentences that is to be supplied by the Master Servicer
shall be evidenced by an Officers' Certificate delivered to the Trust
Administrator and the Trustee by the Master Servicer prior to the Determination
Date immediately following the end of (x) in the case of Bankruptcy Losses
allocable to interest, the Due Period during which any such Realized Loss was
incurred, and (y) in the case

                                       91
<PAGE>

of all other Realized Losses, the Prepayment Period during which any such
Realized Loss was incurred.

                  (b) All Realized Losses on the Mortgage Loans (other than
Excess Losses) shall be allocated by the Trust Administrator on each
Distribution Date as follows: first, to the Class B-6 Certificates; second, to
the Class B-5 Certificates; third, to the Class B-4 Certificates; fourth, to the
Class B-3 Certificates; fifth, to the Class B-2 Certificates; and sixth, to the
Class B-1 Certificates, in each case until the Certificate Principal Balance
thereof has been reduced to zero. Thereafter, upon the reduction of the
Certificate Principal Balances of the Subordinate Certificates to zero, if
Realized Losses are on a Class IO Mortgage Loan, such Realized Losses will be
allocated on any Distribution Date first, to any amounts on deposit in the
Excess Diverted Interest Reserve Account and second, to the Class A-1
Certificates, if the Realized Loss is on a Group I Mortgage Loan, to the Class
A-2 Certificates, if the Realized Loss is on a Group II Mortgage Loan and to the
Class A-3 Certificates, if the Realized Loss is on a Group III Mortgage Loan. If
Realized Losses are on a Class PO Mortgage Loan, such Realized Losses will be
allocated first, to any amounts on deposit in the Excess Diverted Interest
Reserve Account, second, to the Class PO-1 Certificates if the Realized Loss is
on a Group I Mortgage Loan, to the Class PO-2 Certificates, if the Realized Loss
is on a Group II Mortgage Loan and third, to the Class PO-3 Certificates, if the
Realized Loss is on a Group III Mortgage Loan, in each case, in an amount equal
to the related Class PO Percentage of the Realized Losses and third, the
remainder of the Realized Losses will be allocated on any Distribution Date to
the Class A-1 Certificates, if the Realized Loss is on a Group I Mortgage Loan,
to the Class A-2 Certificates, if the Realized Loss is on a Group II Mortgage
Loan and to the Class A-3 Certificates, if the Realized Loss is on a Group III
Mortgage Loan, in each case, to the extent not covered by the Subordinate
Certificates. If a Realized Loss is allocated to the Excess Diverted Interest
Reserve Account, the Trust Administrator shall pay the Group I Excess Diverted
Interest Reserve Deposit, the Group II Excess Diverted Interest Reserve Deposit
or the Group III Excess Diverted Interest Reserve Deposit, as applicable, to the
Available Distribution Amount to which the Realized Loss relates.

                  Excess Losses on a Class IO Mortgage Loan shall be allocated
on any Distribution Date by allocating the related Senior Percentage of the
Excess Loss to the Class A-1 Certificates, if the Realized Loss is on a Group I
Mortgage Loan, to the Class A-2 Certificates, if the Realized Loss is on a Group
II Mortgage Loan and to the Class A-3 Certificates, if the Realized Loss is on a
Group III Mortgage Loan, and the Group I Subordinate Percentage, the Group II
Subordinate Percentage or the Group III Subordinate Percentage, as applicable,
of the Excess Loss to the Subordinate Certificates. Excess Losses on a Class PO
Mortgage Loan will be allocated to the Class PO-1 Certificates, if the Realized
Loss is on a Group I Mortgage Loan, to the Class PO-2 Certificates, if the
Realized Loss is on a Group II Mortgage Loan and to the Class PO-3 Certificates,
if the Realized Loss is on a Group III Mortgage Loan, in an amount equal to the
related Class PO Percentage of the Excess Losses and the remainder of the Excess
Losses will be allocated on any Distribution Date to the Class A Certificates by
allocating the related Senior Percentage of the Excess Loss to the Class A-1
Certificates, if the Realized Loss is on a Group I Mortgage Loan, to the Class
A-2 Certificates, if the Realized Loss is on a Group II Mortgage Loan and to the
Class A-3 Certificates, if the Realized Loss is on a Group III Mortgage Loan,
and the Group I Subordinate Percentage, the Group II Subordinate Percentage or
the Group III Subordinate Percentage, as applicable, of the Excess Loss to the
Subordinate Certificates.

                  Extraordinary Trust Fund Expenses shall be allocated on any
Distribution Date as follows: first, to the Class B-6 Certificates; second, to
the Class B-5 Certificates; third, to the Class B-4 Certificates; fourth, to the
Class B-3 Certificates; fifth, to the Class B-2 Certificates; and sixth, to the
Class B-1 Certificates, in each case until the Certificate Principal Balance of
the related Class has been reduced to zero. Thereafter, the Extraordinary Trust
Fund Expenses will be allocated on any Distribution Date among the Group I
Senior Certificates (other than the Class IO-1 Certificates), the Group II
Senior Certificates (other than the Class IO-2 Certificates) or the Group III
Senior Certificates (other than the Class IO-3 Certificates), as applicable, on
a PRO RATA basis.

                  As used herein, an allocation of a Realized Loss or
Extraordinary Trust Fund Expense on a "PRO RATA basis" among two or more
specified Classes of Certificates means an allocation on a PRO RATA basis, among
the various Classes so specified, to each such Class of Certificates on the
basis of their then outstanding Certificate Principal Balances prior to giving
effect to distributions to be made on such Distribution Date. All Realized
Losses and all other losses allocated to a Class of Certificates hereunder will
be allocated among the Certificates of such Class in proportion to the
Percentage Interests evidenced thereby.

                  (c) Notwithstanding anything to the contrary herein, in no
event shall the Certificate Principal Balance of a Class A Certificate be
reduced more than once in respect of any particular amount both (i) allocable to
such Certificate in respect of Realized Losses or Extraordinary Trust Fund
Expenses pursuant to Section 4.04 and (ii) payable to the Holder of such
Certificate pursuant to Section 4.01(a) as a portion of the Senior Principal
Distribution Amount.

                  SECTION 4.05. Compliance with Withholding Requirements.

                  Notwithstanding any other provision of this Agreement, the
Trust Administrator shall comply with all federal withholding requirements
respecting payments to Certificateholders of interest or original issue discount
that the Trust Administrator reasonably believes are applicable under the Code.
The consent of Certificateholders shall not be required for such withholding. In
the event the Trust Administrator does withhold any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trust Administrator shall
indicate the amount withheld to such Certificateholders.

                  SECTION 4.06. Distributions on the REMIC I Regular Interests.

                  Distributions of principal shall be deemed to be made to the
REMIC I Regular Interests, in each case from the related Loan Group, first, to
REMIC I Regular Interest LT-A1, REMIC I Regular Interest LT-A2 and REMIC I
Regular Interest LT-A3, as applicable, so that the Uncertificated Balance of
each such REMIC I Regular Interest is equal to 0.01% of the excess of (x) the
aggregate Scheduled Principal Balance of the Mortgage Loans in the related Loan
Group over (y) the current Certificate Principal Balance of the Class A
Certificate in such Loan Group (except that if any such excess is a larger
number than in the preceding distribution period, the least amount of principal
shall be distributed to such REMIC I Regular Interests such that the REMIC I
Subordinated Balance Ratio is maintained); and second, any remaining principal
in each Loan Group to REMIC I Regular Interest LT-ZZZ1, REMIC I Regular Interest
LT-ZZZ2 and REMIC I Regular Interest LT-ZZZ3, as applicable (provided that a
portion of the remaining principal equal to the Class

                                       93
<PAGE>

PO Principal Distribution Amount attributable to the Group I Mortgage Loans, the
Class PO Principal Distribution Amount attributable to the Group II Mortgage
Loans and the Class PO Principal Distribution Amount attributable to the Group
III Mortgage Loans will be distributed to REMIC I Regular Interest LT-PO1, REMIC
I Regular Interest LT-PO2 and REMIC I Regular Interest LT-PO3, respectively).
Realized Losses from each Loan Group shall be applied after all distributions
have been made on each Distribution Date, first, to REMIC I Regular Interest
LT-A1, REMIC I Regular Interest LT-A2 and REMIC I Regular Interest LT-A3, as
applicable, so that the Uncertificated Balance of each such REMIC I Regular
Interest is equal to 0.01% of the excess of (x) the aggregate Scheduled
Principal Balance of the Mortgage Loans in the related Loan Group over (y) the
current Certificate Principal Balance of the Class A Certificate in the related
Loan Group (except that if any such excess is a larger number than in the
preceding distribution period, the least amount of Realized Losses shall be
applied to such REMIC I Regular Interests such that the REMIC I Subordinated
Balance Ratio is maintained); and second, any remaining Realized Losses from
each Loan Group shall be allocated to REMIC I Regular Interest LT-ZZZ1, REMIC I
Regular Interest LT- ZZZ and REMIC I Regular Interest LT-ZZZ3, as applicable
(except that if a Realized Loss is recognized with respect to a PO Mortgage Loan
in any of the Group I Mortgage Loans, Group II Mortgage Loans or Group III
Mortgage Loans, the applicable portion of such Realized Loss will be allocated
to REMIC I Regular Interest LT-PO1, REMIC I Regular Interest LT-PO2 and REMIC I
Regular Interest LT-PO3, respectively).

                  SECTION 4.07. Commission Reporting.

                  (a) The Trust Administrator and the Master Servicer shall
reasonably cooperate with the Depositor in connection with satisfying the
reporting requirements under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). The Trust Administrator shall prepare on behalf of the
Trust Fund any Forms 8-K and 10-K customary for similar securities as required
by the Exchange Act and the Rules and Regulations of the Securities and Exchange
Commission thereunder, and the Depositor shall sign (or shall cause another
entity acceptable to the Securities and Exchange Commission to sign) and the
Trust Administrator shall file (via the Securities and Exchange Commission's
Electronic Data Gathering and Retrieval System) such forms on behalf of the
Depositor (or such other entity). The Depositor hereby grants to the Trust
Administrator a limited power of attorney to execute any Form 8-K and file each
such document on behalf of the Depositor. Such power of attorney shall continue
until the earlier of (i) receipt by the Trust Administrator from the Depositor
of written termination of such power of attorney and (ii) the termination of the
Trust. Notwithstanding anything herein to the contrary, the Depositor, and not
the Trust Administrator, shall be responsible for executing each Form 10-K filed
on behalf of the Trust.

                  (b) Each Form 8-K shall be filed by the Trust Administrator
within 15 days after each Distribution Date, with a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Subject to
Section 4.07(e), prior to March 30th of each year (or such earlier date as may
be required by the Exchange Act and the Rules and Regulations of the Securities
and Exchange Commission), the Trust Administrator shall file a Form 10-K, in
substance as required by applicable law or applicable Securities and Exchange
Commission staff's interpretations. The Trust Administrator shall prepare such
Form 10-K and provide the Depositor with such Form 10-K

                                       94
<PAGE>

not later than March 20th of each year, subject to Section 4.07(e). Following
its receipt thereof, the Depositor shall execute such Form 10-K and provide the
original of such Form 10-K to the Trust Administrator not later than March 25th
(or, if the applicable March 25th is not a Business Day, the next succeeding
Business Day) of each year; provided, however, that if the filing of such Form
10-K shall be required to occur on a date earlier than March 30th of each year
as may be required by the Exchange Act and the Rules and Regulations of the
Securities and Exchange Commission, then the time periods for preparation and
execution of such Form 10-K set forth in this sentence shall be adjusted
accordingly). Such Form 10-K when filed shall include as exhibits the Master
Servicer's annual statement of compliance described under Section 3.20 and the
accountant's report described under Section 3.21, in each case to the extent
they have been timely delivered to the Trust Administrator. If they are not so
timely delivered, the Trust Administrator shall file an amended Form 10-K
including such documents as exhibits reasonably promptly after they are
delivered to the Trust Administrator. The Trust Administrator shall have no
liability with respect to any failure to properly prepare or file such periodic
reports resulting from or relating to the Trust Administrator's inability or
failure to obtain any information not resulting from its own negligence or
willful misconduct. The Form 10-K shall also include a certification in the form
attached hereto as Exhibit J-1 (the "Certification"), which shall be signed by
the senior officer of the Depositor in charge of securitization.

                  (c) In addition, (x) the Trust Administrator shall sign a
certification (in the form attached hereto as Exhibit J-2) for the benefit of
the Depositor and its officers, directors and Affiliates regarding certain
aspects of the Certification (the "Trust Administrator Certification");
provided, however, that the Trust Administrator shall not undertake an analysis
of the accountant's report attached as an exhibit to the Form 10-K, and (y) the
Master Servicer shall sign a certification (in the form attached hereto as
Exhibit J-3) for the benefit of the Depositor, the Trust Administrator and their
officers, directors and Affiliates regarding certain aspects of the
Certification (the "Master Servicer Certification"). The Master Servicer
Certification shall be delivered to the Depositor and the Trust Administrator no
later than March 15th or if such day is not a Business Day, the preceding
Business Day, each year (subject to Section 4.07(e) hereof). The Trust
Administrator Certification shall be delivered to the Depositor no later than
March 15th or if such day is not a Business Day, the preceding Business Day,
each year (subject to Section 4.07(e) hereof).

                  In addition, (A) the Trust Administrator shall indemnify and
hold harmless the Depositor and its officers, directors and Affiliates from and
against any actual losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments and other costs and
expenses arising out of third party claims based upon a breach of the Trust
Administrator's obligations under this Section 4.07 or any material misstatement
or omission contained in the Trust Administrator Certification, and (B) the
Master Servicer shall indemnify and hold harmless the Depositor, the Trust
Administrator and their respective officers, directors and Affiliates from and
against any actual losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments and other costs and
expenses that such Person may sustain arising out of third party claims based
upon a breach of the Master Servicer's obligations under this Section 4.07(c),
any material misstatement or omission contained in the Master Servicer's
Certification or any information correctly derived by the Trust Administrator
and included in a Form 8-K or Form 10-K from information provided to the Trust
Administrator by the Master Servicer under this Agreement. If the
indemnification provided for herein is unavailable or insufficient to

                                       95
<PAGE>

hold harmless the Depositor, then (i) the Trust Administrator agrees that it
shall contribute to the amount paid or payable by the Depositor as a result of
the losses, claims, damages or liabilities of the Depositor in such proportion
as is appropriate to reflect the relative fault of the Depositor on the one hand
and the Trust Administrator on the other and (ii) the Master Servicer agrees
that it shall contribute to the amount paid or payable by the Depositor as a
result of the losses, claims, damages or liabilities of the Depositor in such
proportion as is appropriate to reflect the relative fault of the Depositor on
the one hand and the Master Servicer on the other.

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

                  (e) Prior to January 30th of the first year in which the Trust
Administrator is able to do so under applicable law, the Trust Administrator
shall file a Form 15 Suspension Notification with respect to the Trust Fund.

                  (f) To the extent that, following the Closing Date, the
Depositor certifies that reports and certifications differing from those
required under this Section 4.07 comply with the reporting requirements under
the Exchange Act, the Trust Administrator and the Master Servicer hereby agree
that they will reasonably cooperate to amend the provisions of this Section 4.07
in order to comply with such amended reporting requirements and such amendment
of this Section 4.07; provided, however, that the Trust Administrator shall not
be responsible for executing any Form 10- K or the Certification. Any such
amendment may result in the reduction of the reports filed by the Depositor
under the Exchange Act.

                  SECTION 4.08. Excess Diverted Interest Reserve Account

                  (a) No later than the Closing Date, the Trust Administrator
shall establish and maintain with itself, a separate, segregated trust account
titled, "Excess Diverted Interest Reserve Account, Citibank, N.A., as Trust
Administrator for U.S. Bank National Association, as Trustee, in trust for the
registered holders of Citigroup Mortgage Loan Trust, Series 2003-UST1, Mortgage
Pass-Through Certificates."

                  (b) On each Distribution Date as to which there is an Excess
Diverted Interest Reserve Amount payable to a Class of Class A Certificates, the
Trust Administrator shall deposit into the Excess Diverted Interest Reserve
Account the amount of such Excess Diverted Interest Reserve Amount, rather than
distributing such amounts to the Class R Certificateholders. On each such
Distribution Date, the Trust Administrator shall hold all such amounts for the
benefit of the Holders of the Class A Certificates, and will distribute such
amounts to the Holders of the Class A Certificates, in the amounts and
priorities set forth in Section 4.01.

                  (c) For federal and state income tax purposes, the Excess
Diverted Interest Reserve Account will be a "qualified reserve fund" within the
meaning of Code Section 860(G)(7)(B).

                                       96
<PAGE>

                  (d) At the written direction of the Holders of a majority in
Percentage Interest in the Class R Certificates, the Trust Administrator shall
direct any depository institution maintaining the Excess Diverted Interest
Reserve Account to invest the funds in such account in one or more Permitted
Investments, selected in writing by the Holders of a majority in Percentage
Interest in the Class R Certificates, bearing interest or sold at a discount,
and maturing, unless payable on demand, (i) no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement, if a Person other than the Trust
Administrator or an Affiliate manages or advises such investment, and (ii) no
later than the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if the Trust Administrator or an Affiliate
manages or advises such investment. Interest earned on such investment shall be
deposited into the Excess Diverted Interest Reserve Account.

                  (f) For federal tax return and information reporting, the
right of the Holders of the Class A Certificates to receive payments from the
Excess Diverted Interest Reserve Account in respect of any Excess Diverted
Interest Reserve Amount shall be assigned a value of zero.

                  (g) On the final Distribution Date, all Excess Diverted
Interest Reserve Amounts remaining in the Excess Diverted Interest Reserve
Account, if any, shall be paid to the Holders of the Class R Certificates.

                                THE CERTIFICATES

                  SECTION 5.01. The Certificates.

                  (a) The Certificates in the aggregate will represent the
entire beneficial ownership interest in the Mortgage Loans and all other assets
included in REMIC II. At the Closing Date, the aggregate Certificate Principal
Balance of the Certificates will equal the aggregate Stated Principal Balance of
the Mortgage Loans.

                  The Certificates will be substantially in the forms annexed
hereto as Exhibits A-1 through A-16. The Certificates of each Class will be
issuable in registered form only, in denominations of authorized Percentage
Interests as described in the definition thereof. Each Certificate will share
ratably in all rights of the related Class.

                  Upon original issue, the Certificates shall be executed,
authenticated and delivered by the Trust Administrator to or upon the order of
the Depositor. The Certificates shall be executed and attested by manual or
facsimile signature on behalf of the Trust Administrator by an authorized
signatory. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Trust Administrator
shall bind the Trust Administrator, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless there appears on such Certificate
a certificate of authentication substantially in the form provided herein
executed by the Trust Administrator by manual signature, and such certificate of
authentication shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

                  (b) The Class A Certificates, the Class IO Certificates and
the Class PO Certificates shall initially be issued as one or more Certificates
held by the Book- Entry Custodian or, if appointed to hold such Certificates as
provided below, the Depository and registered in the name of the Depository or
its nominee and, except as provided below, registration of such Certificates may
not be transferred by the Trust Administrator except to another Depository that
agrees to hold such Certificates for the respective Certificate Owners with
Ownership Interests therein. The Certificate Owners shall hold their respective
Ownership Interests in and to such Certificates through the book-entry
facilities of the Depository and, except as provided below, shall not be
entitled to definitive, fully registered Certificates ("Definitive
Certificates") in respect of such Ownership Interests. All transfers by
Certificate Owners of their respective Ownership Interests in the Book- Entry
Certificates shall be made in accordance with the procedures established by the
Depository Participant or brokerage firm representing such Certificate Owner.
Each Depository Participant shall only transfer the Ownership Interests in the
Book-Entry Certificates of Certificate Owners it represents or of brokerage
firms for which it acts as agent in accordance with the Depository's normal
procedures. The Trust Administrator is hereby initially appointed as the Book-
Entry Custodian and hereby agrees to act as such in accordance herewith and in
accordance with the

                                       98
<PAGE>

agreement that it has with the Depository authorizing it to act as such. The
Book-Entry Custodian may, and if it is no longer qualified to act as such, the
Book-Entry Custodian shall, appoint, by a written instrument delivered to the
Depositor, the Master Servicer, the Trust Administrator, the Trustee (if the
Trust Administrator is not the Book-Entry Custodian) and any other transfer
agent (including the Depository or any successor Depository) to act as
Book-Entry Custodian under such conditions as the predecessor Book-Entry
Custodian and the Depository or any successor Depository may prescribe, provided
that the predecessor Book-Entry Custodian shall not be relieved of any of its
duties or responsibilities by reason of any such appointment of other than the
Depository. If the Trust Administrator resigns or is removed in accordance with
the terms hereof, the successor trustee or, if it so elects, the Depository
shall immediately succeed to its predecessor's duties as Book-Entry Custodian.
The Depositor shall have the right to inspect, and to obtain copies of, any
Certificates held as Book-Entry Certificates by the Book-Entry Custodian.

                  The Trustee, the Trust Administrator, the Master Servicer and
the Depositor may for all purposes (including the making of payments due on the
Book-Entry Certificates) deal with the Depository as the authorized
representative of the Certificate Owners with respect to the Book-Entry
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the Book-Entry
Certificates shall be limited to those established by law and agreements between
such Certificate Owners and the Depository Participants and brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of the Book-Entry Certificates with respect
to any particular matter shall not be deemed inconsistent if they are made with
respect to different Certificate Owners. The Trust Administrator may establish a
reasonable record date in connection with solicitations of consents from or
voting by Certificateholders and shall give notice to the Depository of such
record date.

                  If (i)(A) the Depositor advises the Trust Administrator in
writing that the Depository is no longer willing or able to properly discharge
its responsibilities as Depository, and (B) the Depositor is unable to locate a
qualified successor, (ii) the Depositor at its option advises the Trust
Administrator in writing that it elects to terminate the book-entry system
through the Depository or (iii) after the occurrence of a Master Servicer Event
of Default, Certificate Owners representing in the aggregate not less than 51%
of the Ownership Interests of the Book-Entry Certificates advise the Trust
Administrator through the Depository, in writing, that the continuation of a
book-entry system through the Depository is no longer in the best interests of
the Certificate Owners, the Trust Administrator shall notify all Certificate
Owners, through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to Certificate Owners requesting the
same. Upon surrender to the Trust Administrator of the Book- Entry Certificates
by the Book-Entry Custodian or the Depository, as applicable, accompanied by
registration instructions from the Depository for registration of transfer, the
Trust Administrator shall issue the Definitive Certificates. Such Definitive
Certificates will be issued in minimum denominations of $100,000, except that
any beneficial ownership that was represented by a Book-Entry Certificate in an
amount less than $100,000 immediately prior to the issuance of a Definitive
Certificate shall be issued in a minimum denomination equal to the amount
represented by such Book-Entry Certificate. None of the Depositor, the Master
Servicer, the Trust Administrator nor the Trustee shall be liable for any delay
in the delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates all references herein to obligations

                                       99
<PAGE>

imposed upon or to be performed by the Depository shall be deemed to be imposed
upon and performed by the Trust Administrator, to the extent applicable with
respect to such Definitive Certificates, and the Trust Administrator shall
recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

                  SECTION 5.02. Registration of Transfer and Exchange of
                                Certificates.

                  (a) The Trust Administrator shall cause to be kept at one of
the offices or agencies to be appointed by the Trust Administrator in accordance
with the provisions of Section 8.12 a Certificate Register for the Certificates
in which, subject to such reasonable regulations as it may prescribe, the Trust
Administrator shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided.

                  (b) No transfer of any Subordinate Certificate or Residual
Certificate (the "Private Certificates") shall be made unless that transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer of a Private Certificate is to be made without
registration or qualification (other than in connection with the initial
transfer of any such Certificate by the Depositor), the Trust Administrator
shall require, receipt of: (i) if such transfer is purportedly being made in
reliance upon Rule 144A under the 1933 Act, written certifications from the
Certificateholder desiring to effect the transfer and from such
Certificateholder's prospective transferee, substantially in the forms attached
hereto as Exhibit F-1; and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee, the Trust Administrator, the Master Servicer, in its
capacity as such, or the Trust Fund), together with copies of the written
certification(s) of the Certificateholder desiring to effect the transfer and/or
such Certificateholder's prospective transferee upon which such Opinion of
Counsel is based, if any. Neither the Depositor nor the Trust Administrator is
obligated to register or qualify the Private Certificates under the 1933 Act or
any other securities laws or to take any action not otherwise required under
this Agreement to permit the transfer of such Certificates without registration
or qualification. Any Certificateholder desiring to effect the transfer of a
Private Certificate shall, and does hereby agree to, indemnify the Trustee, the
Trust Administrator, the Depositor and the Master Servicer against any liability
that may result if the transfer is not so exempt or is not made in accordance
with such federal and state laws.

                  (c) No transfer of a Private Certificate or any interest
therein shall be made to any Plan subject to ERISA or Section 4975 of the Code,
any Person acting, directly or indirectly, on behalf of any such Plan or any
Person acquiring such Certificates with "Plan Assets" of a Plan within the
meaning of the DOL Regulations ("Plan Assets"), as certified by such transferee
in the form of Exhibit G, unless the Trust Administrator is provided with an
Opinion of Counsel, which establishes to the satisfaction of the Depositor, the
Trustee, the Trust Administrator and the Master Servicer that the purchase of
such Certificates is permissible under applicable law, will not constitute or
result in any prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the Depositor, the Master Servicer, the Trustee, the Trust
Administrator or the Trust Fund to any obligation or liability (including
obligations or liabilities under ERISA or Section 4975 of the Code)

                                      100
<PAGE>

in addition to those undertaken in this Agreement, which Opinion of Counsel
shall not be an expense of the Depositor, the Master Servicer, the Trustee, the
Trust Administrator or the Trust Fund. An Opinion of Counsel, any certification
or a deemed representation will not be required in connection with the initial
transfer of any such Certificate by the Depositor (in which case, the Depositor
shall have deemed to have represented that such transferee is not a Plan or a
Person investing Plan Assets) and the Trust Administrator shall be entitled to
conclusively rely upon a representation (which, upon the request of the Trust
Administrator, shall be a written representation) from the Depositor of the
status of such transferee.

                  If any Subordinate Certificate or Residual Certificate or any
interest therein is acquired or held in violation of the provisions of the
preceding two paragraphs, the next preceding permitted beneficial owner will be
treated as the beneficial owner of that Certificate retroactive to the date of
transfer to the purported beneficial owner. Any purported beneficial owner whose
acquisition or holding of any such Certificate or interest therein was effected
in violation of the provisions of the preceding two paragraphs shall indemnify
and hold harmless the Depositor, the Master Servicer, the Trustee, the Trust
Administrator and the Trust Fund from and against any and all liabilities,
claims, costs or expenses incurred by those parties as a result of that
acquisition or holding.

                  (d) (i) Each Person who has or who acquires any Ownership
Interest in a Residual Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the
following provisions and to have irrevocably authorized the Trust Administrator
or its designee under clause (iii)(A) below to deliver payments to a Person
other than such Person and to negotiate the terms of any mandatory sale under
clause (iii)(B) below and to execute all instruments of Transfer and to do all
other things necessary in connection with any such sale. The rights of each
Person acquiring any Ownership Interest in a Residual Certificate are expressly
subject to the following provisions:

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

                           (B) In connection with any proposed Transfer of any
                  Ownership Interest in a Residual Certificate, the Trust
                  Administrator shall require delivery to it and shall not
                  register the Transfer of any Residual Certificate until its
                  receipt of an affidavit and agreement (a "Transfer Affidavit
                  and Agreement"), in the form attached hereto as Exhibit F-2,
                  from the proposed Transferee, in form and substance
                  satisfactory to the Trust Administrator, representing and
                  warranting, among other things, that such Transferee is a
                  Permitted Transferee, that it is not acquiring its Ownership
                  Interest in the Residual Certificate that is the subject of
                  the proposed Transfer as a nominee, trustee or agent for any
                  Person that is not a Permitted Transferee, that for so long as
                  it retains its Ownership Interest in a Residual Certificate,
                  it will endeavor to remain a Permitted Transferee, and that it
                  has reviewed the provisions of this Section 5.02(d) and agrees
                  to be bound by them.

<PAGE>

                           (C) Notwithstanding the delivery of a Transfer
                  Affidavit and Agreement by a proposed Transferee under clause
                  (B) above, if a Responsible Officer of the Trust Administrator
                  who is assigned to this transaction has actual knowledge that
                  the proposed Transferee is not a Permitted Transferee, no
                  Transfer of an Ownership Interest in a Residual Certificate to
                  such proposed Transferee shall be effected.

                           (D) Each Person holding or acquiring any Ownership
                  Interest in a Residual Certificate shall agree (x) to require
                  a Transfer Affidavit and Agreement from any other Person to
                  whom such Person attempts to transfer its Ownership Interest
                  in a Residual Certificate and (y) not to transfer its
                  Ownership Interest unless it provides a transferor affidavit
                  (a "Transferor Affidavit"), in the form attached hereto as
                  Exhibit F-2, to the Trust Administrator stating that, among
                  other things, it has no actual knowledge that such other
                  Person is not a Permitted Transferee.

                           (E) Each Person holding or acquiring an Ownership
                  Interest in a Residual Certificate, by purchasing an Ownership
                  Interest in such Certificate, agrees to give the Trust
                  Administrator written notice that it is a "pass-through
                  interest holder" within the meaning of temporary Treasury
                  regulation Section 1.67- 3T(a)(2)(i)(A) immediately upon
                  acquiring an Ownership Interest in a Residual Certificate, if
                  it is, or is holding an Ownership Interest in a Residual
                  Certificate on behalf of, a "pass- through interest holder."

                           (ii) The Trust Administrator will register the
                  Transfer of any Residual Certificate only if it shall have
                  received the Transfer Affidavit and Agreement and all of such
                  other documents as shall have been reasonably required by the
                  Trust Administrator as a condition to such registration. In
                  addition, no Transfer of a Residual Certificate shall be made
                  unless the Trust Administrator shall have received a
                  representation letter from the Transferee of such Certificate
                  to the effect that such Transferee is a Permitted Transferee.

                           (iii) (A) If any purported Transferee shall become a
                  Holder of a Residual Certificate in violation of the
                  provisions of this Section 5.02(d), then the last preceding
                  Permitted Transferee shall be restored, to the extent
                  permitted by law, to all rights as holder thereof retroactive
                  to the date of registration of such Transfer of such Residual
                  Certificate. The Trust Administrator shall be under no
                  liability to any Person for any registration of Transfer of a
                  Residual Certificate that is in fact not permitted by this
                  Section 5.02(d) or for making any payments due on such
                  Certificate to the holder thereof or for taking any other
                  action with respect to such holder under the provisions of
                  this Agreement.

                                    (B) If any purported Transferee shall become
                  a holder of a Residual Certificate in violation of the
                  restrictions in this Section 5.02(d) and to the extent that
                  the retroactive restoration of the rights of the holder of
                  such Residual Certificate as described in clause (iii)(A)
                  above shall be invalid, illegal or unenforceable, then the
                  Trust Administrator shall have the right, without notice to
                  the holder or any prior holder of such Residual Certificate,
                  to sell such Residual

                                      102
<PAGE>

                  Certificate to a purchaser selected by the Trust Administrator
                  on such terms as the Trust Administrator may choose. Such
                  purported Transferee shall promptly endorse and deliver each
                  Residual Certificate in accordance with the instructions of
                  the Trust Administrator. Such purchaser may be the Trust
                  Administrator itself or any Affiliate of the Trust
                  Administrator. The proceeds of such sale, net of the
                  commissions (which may include commissions payable to the
                  Trust Administrator or its Affiliates), expenses and taxes
                  due, if any, will be remitted by the Trust Administrator to
                  such purported Transferee. The terms and conditions of any
                  sale under this clause (iii)(B) shall be determined in the
                  sole discretion of the Trust Administrator, and the Trust
                  Administrator shall not be liable to any Person having an
                  Ownership Interest in a Residual Certificate as a result of
                  its exercise of such discretion.

                           (iv) The Trust Administrator shall make available to
                  the Internal Revenue Service and those Persons specified by
                  the REMIC Provisions all information necessary to compute any
                  tax imposed (A) as a result of the Transfer of an Ownership
                  Interest in a Residual Certificate to any Person who is a
                  Disqualified Organization, including the information described
                  in Treasury regulations sections 1.860D-1(b)(5) and
                  1.860E-2(a)(5) with respect to the "excess inclusions" of such
                  Residual Certificate and (B) as a result of any regulated
                  investment company, real estate investment trust, common trust
                  fund, partnership, trust, estate or organization described in
                  Section 1381 of the Code that holds an Ownership Interest in a
                  Residual Certificate having as among its record holders at any
                  time any Person which is a Disqualified Organization.
                  Reasonable compensation for providing such information may be
                  accepted by the Trust Administrator.

                           (v) The provisions of this Section 5.02(d) set forth
                  prior to this subsection (v) may be modified, added to or
                  eliminated, provided that there shall have been delivered to
                  the Trust Administrator at the expense of the party seeking to
                  modify, add to or eliminate any such provision the following:

                                    (A) written notification from the Rating
                  Agencies to the effect that the modification, addition to or
                  elimination of such provisions will not cause the Rating
                  Agencies to downgrade its then-current ratings of any Class of
                  Certificates; and

                                    (B) an Opinion of Counsel, in form and
                  substance satisfactory to the Trust Administrator, to the
                  effect that such modification of, addition to or elimination
                  of such provisions will not cause Any Trust REMIC to cease to
                  qualify as a REMIC and will not cause (x) Any Trust REMIC to
                  be subject to an entity-level tax caused by the Transfer of
                  any Residual Certificate to a Person that is not a Permitted
                  Transferee or (y) a Person other than the prospective
                  transferee to be subject to a REMIC-tax caused by the Transfer
                  of a Residual Certificate to a Person that is not a Permitted
                  Transferee.

                  (e) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the Trust
Administrator maintained for such

                                      103
<PAGE>

purpose pursuant to Section 8.12, the Trust Administrator shall execute,
authenticate and deliver, in the name of the designated Transferee or
Transferees, one or more new Certificates of the same Class of a like aggregate
Percentage Interest.

                  (f) At the option of the Holder thereof, any Certificate may
be exchanged for other Certificates of the same Class with authorized
denominations and a like aggregate Percentage Interest, upon surrender of such
Certificate to be exchanged at any office or agency of the Trust Administrator
maintained for such purpose pursuant to Section 8.12. Whenever any Certificates
are so surrendered for exchange the Trust Administrator shall execute,
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
transfer or exchange shall (if so required by the Trust Administrator) be duly
endorsed by, or be accompanied by a written instrument of transfer in the form
satisfactory to the Trust Administrator duly executed by, the Holder thereof or
his attorney duly authorized in writing.

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

                  (h) All Certificates surrendered for transfer and exchange
shall be canceled and destroyed by the Trust Administrator in accordance with
its customary procedures.

                  SECTION 5.03. Mutilated, Destroyed, Lost or Stolen
                                Certificates.

                  If (i) any mutilated Certificate is surrendered to the Trust
Administrator, or the Trust Administrator receive evidence to its satisfaction
of the destruction, loss or theft of any Certificate, and (ii) there is
delivered to the Trust Administrator such security or indemnity as may be
required by them to save each of the Trustee and the Trust Administrator
harmless, then, in the absence of actual knowledge by the Trust Administrator
that such Certificate has been acquired by a bona fide purchaser, the Trust
Administrator shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same
Class and of like denomination and Percentage Interest. Upon the issuance of any
new Certificate under this Section, the Trust Administrator may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trust Administrator) connected therewith. Any replacement
Certificate issued pursuant to this Section shall constitute complete and
indefeasible evidence of ownership in the applicable REMIC created hereunder, as
if originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                  SECTION 5.04. Persons Deemed Owners.

                  The Depositor, the Master Servicer, the Trustee, the Trust
Administrator and any agent of any of them may treat the Person in whose name
any Certificate is registered as the owner of such Certificate for the purpose
of receiving distributions pursuant to Section 4.01 and for all

                                      104

other purposes whatsoever, and none of the Depositor, the Master Servicer, the
Trustee, the Trust Administrator or any agent of any of them shall be affected
by notice to the contrary.

                  SECTION 5.05. Certain Available Information.

                  On or prior to the date of the first sale of any Private
Certificate to an Independent third party, the Depositor shall provide to the
Trust Administrator ten copies of any private placement memorandum or other
disclosure document used by the Depositor in connection with the offer and sale
of the Private Certificates. In addition, if any such private placement
memorandum or disclosure document is revised, amended or supplemented at any
time following the delivery thereof to the Trust Administrator, the Depositor
promptly shall inform the Trust Administrator of such event and shall deliver to
the Trust Administrator ten copies of the private placement memorandum or
disclosure document, as revised, amended or supplemented. The Trust
Administrator shall maintain at its Corporate Trust Office and shall make
available free of charge during normal business hours for review by any Holder

                      THE DEPOSITOR AND THE MASTER SERVICER

                  SECTION 6.01. Liability of the Depositor and the Master
                                Servicer.

                  The Depositor and the Master Servicer each shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
by this Agreement and undertaken hereunder by the Depositor and the Master
Servicer herein.

                  SECTION 6.02. Merger or Consolidation of the Depositor or the
                                Master Servicer.

                  Subject to the following paragraph, the Depositor will keep in
full effect its existence, rights and franchises as a corporation under the laws
of the jurisdiction of its incorporation. Subject to the following paragraph,
the Master Servicer will keep in full effect its existence, rights and
franchises as a corporation under the laws of the jurisdiction of its
incorporation. The Depositor and the Master Servicer each will obtain and
preserve its qualification to do business as a foreign corporation in each
jurisdiction in which such qualification is or shall be necessary to protect the
validity and enforceability of this Agreement, the Certificates or any of the
Mortgage Loans and to perform its respective duties under this Agreement.

                  The Depositor or the Master Servicer may be merged or
consolidated with or into any Person, or transfer all or substantially all of
its assets to any Person, in which case any Person resulting from any merger or
consolidation to which the Depositor or the Master Servicer shall be a party, or
any Person succeeding to the business of the Depositor or the Master Servicer,
shall be the successor of the Depositor or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the Rating Agencies' reaffirm the
ratings of the Certificates in effect immediately prior to such merger or
consolidation and affirm that such ratings will not be qualified, reduced or
withdrawn as a result thereof (as evidenced by a letter to such effect from the
Rating Agencies).

                  SECTION 6.03. Limitation on Liability of the Depositor, the
                                Master Servicer and Others.

                  None of the Depositor, the Master Servicer or any of the
directors, officers, employees or agents of the Depositor or the Master Servicer
shall be under any liability to the Trust Fund or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, the Master Servicer or any such
person against any breach of warranties, representations or covenants made
herein, or against any specific liability imposed on the Master Servicer
pursuant hereto, or against any liability which would otherwise be imposed by
reason of willful misfeasance, bad faith or negligence in the performance of
duties or by reason of reckless disregard of obligations and duties hereunder.
The Depositor, the Master Servicer and any director, officer, employee or agent
of the Depositor or the Master Servicer may rely in good faith on any

                                      106
<PAGE>

document of any kind which, PRIMA FACIE, is properly executed and submitted by
any Person respecting any matters arising hereunder. The Depositor, the Master
Servicer and any director, officer, employee or agent of the Depositor or the
Master Servicer shall be indemnified and held harmless by the Trust Fund against
any loss, liability or expense incurred in connection with any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense to any specific Mortgage Loan or Mortgage Loans (except as any such
loss, liability or expense shall be otherwise reimbursable pursuant to this
Agreement) or any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of duties hereunder or
by reason of reckless disregard of obligations and duties hereunder. Neither the
Depositor nor the Master Servicer shall be under any obligation to appear in,
prosecute or defend any legal action unless such action is related to its
respective duties under this Agreement and, in its opinion, does not involve it
in any expense or liability; provided, however, that each of the Depositor and
the Master Servicer may in its discretion undertake any such action which it may
deem necessary or desirable with respect to this Agreement and the rights and
duties of the parties hereto and the interests of the Certificateholders
hereunder. In such event, unless the Depositor or the Master Servicer acts
without the consent of Holders of Certificates entitled to at least 51% of the
Voting Rights (which consent shall not be necessary in the case of litigation or
other legal action by either to enforce their respective rights or defend
themselves hereunder), the legal expenses and costs of such action and any
liability resulting therefrom (except any loss, liability or expense incurred by
reason of willful misfeasance, bad faith or negligence in the performance of
duties hereunder or by reason of reckless disregard of obligations and duties
hereunder) shall be expenses, costs and liabilities of the Trust Fund, and the
Depositor (subject to the limitations set forth above) and the Master Servicer
shall be entitled to be reimbursed therefor from the Collection Account as and
to the extent provided in Section 3.11, any such right of reimbursement being
prior to the rights of the Certificateholders to receive any amount in the
Collection Account.

                  SECTION 6.04. Limitation on Resignation of the Master
                                Servicer.

                  The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (i) upon determination that its duties
hereunder are no longer permissible under applicable law or (ii) with the
written consent of the Trustee and the Trust Administrator, which consent may
not be unreasonably withheld, with written confirmation from the Rating Agencies
(which confirmation shall be furnished to the Depositor, the Trustee and the
Trust Administrator) that such resignation will not cause the Rating Agencies to
reduce the then current rating of the Class A Certificates and provided that a
qualified successor has agreed to assume the duties and obligations of the
Master Servicer hereunder. Any such determination pursuant to clause (i) of the
preceding sentence permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect obtained at the expense of the
Master Servicer and delivered to the Trustee and the Trust Administrator. No
resignation of the Master Servicer shall become effective until the Trust
Administrator or a successor servicer shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement.

                  Except as expressly provided herein, the Master Servicer shall
not assign nor transfer any of its rights, benefits or privileges hereunder to
any other Person, nor delegate to or subcontract with, nor authorize or appoint
any other Person to perform any of the duties, covenants or obligations

                                      107
<PAGE>

to be performed by the Master Servicer hereunder. If, pursuant to any provision
hereof, the duties of the Master Servicer are transferred to a successor master
servicer, the entire amount of the Servicing Fee and other compensation payable
to the Master Servicer pursuant hereto shall thereafter be payable to such
successor master servicer.

                  SECTION 6.05. Rights of the Depositor in Respect of the Master
                                Servicer.

                  The Master Servicer shall afford (and any Sub-Servicing
Agreement shall provide that each Sub-Servicer shall afford) the Depositor, the
Trustee and the Trust Administrator, upon reasonable notice, during normal
business hours, access to all records maintained by the Master Servicer (and any
such Sub-Servicer) in respect of the Master Servicer's rights and obligations
hereunder and access to officers of the Master Servicer (and those of any such
Sub-Servicer) responsible for such obligations. Upon request, the Master
Servicer shall furnish to the Depositor, the Trustee and the Trust Administrator
its (and any such Sub-Servicer's) most recent financial statements of the parent
company of the Master Servicer and such other information relating to the Master
Servicer's capacity to perform its obligations under this Agreement that it
possesses. To the extent such information is not otherwise available to the
public, the Depositor, the Trustee and the Trust Administrator shall not
disseminate any information obtained pursuant to the preceding two sentences
without the Master Servicer's written consent, except as required pursuant to
this Agreement or to the extent that it is appropriate to do so (i) in working
with legal counsel, auditors, taxing authorities or other governmental agencies,
rating agencies or reinsurers or (ii) pursuant to any law, rule, regulation,
order, judgment, writ, injunction or decree of any court or governmental
authority having jurisdiction over the Depositor, the Trustee, the Trust
Administrator or the Trust Fund, and in either case, the Depositor, the Trustee
or the Trust Administrator, as the case may be, shall use its best efforts to
assure the confidentiality of any such disseminated non-public information. The
Depositor may, but is not obligated to, enforce the obligations of the Master
Servicer under this Agreement and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of the Master Servicer
under this Agreement or exercise the rights of the Master Servicer under this
Agreement; provided that the Master Servicer shall not be relieved of any of its
obligations under this Agreement by virtue of such performance by the Depositor
or its designee. The Depositor shall not have any responsibility or liability
for any action or failure to act by the Master Servicer and is not obligated to
supervise the performance of the Master Servicer under this Agreement or
otherwise.

                  required to be made from its own funds on any Master Servicer
                  Remittance Date pursuant to Section 4.03) required to be made

                  continues unremedied for a period of one Business Day after
                  the date upon which written notice of such failure, requiring
                  the same to be remedied, shall have been given to the Master
                  Servicer by the Depositor, the Trust Administrator or the
                  Trustee (in which case notice shall be provided by telecopy),
                  or to the Master Servicer, the Depositor, the Trust
                  Administrator and the Trustee by the Holders of Certificates
                  entitled to at least 25% of the Voting Rights; or

                  continues unremedied for a period of 30 days after the earlier

                  Certificates entitled to at least 25% of the Voting Rights and
                  (ii) actual knowledge of such failure by a Servicing Officer
                  of the Master Servicer; or

                           (iii) a decree or order of a court or agency or
                  supervisory authority having jurisdiction in the premises in
                  an involuntary case under any present or future federal or

                  similar proceeding, or for the winding-up or liquidation of
                  its affairs, shall have been entered against the Master
                  Servicer and if such proceeding is being contested by the
                  Master Servicer in good faith such decree or order shall have
                  remained in force undischarged or unstayed for a period of 60
                  consecutive days or results in the entry of an order for
                  relief or any such adjudication or appointment; or

                           (iv) the Master Servicer shall consent to the

                  insolvency, readjustment of debt, marshalling of assets and
                  liabilities or similar proceedings of or relating to the

<PAGE>

                           (v) the Master Servicer shall admit in writing its
                  inability to pay its debts generally as they become due, file
                  a petition to take advantage of any applicable insolvency or
                  reorganization statute, make an assignment for the benefit of
                  its creditors, or voluntarily suspend payment of its
                  obligations; or

                           (vi) any failure of the Master Servicer to make any
                  P&I Advance on any Master Servicer Remittance Date required to
                  be made from its own funds pursuant to Section 4.03 which
                  continues unremedied for a period of one Business Day after
                  the date upon which written notice of such failure (which
                  notice the Trust Administrator must provide by 3:00 p.m. New
                  York time on the Business Day following the Master Servicer
                  Remittance Date), requiring the same to be remedied, shall
                  have been given to the Master Servicer by the Trust
                  Administrator.

                  If a Master Servicer Event of Default described in clauses (i)
through (v) of this Section shall occur, then, and in each and every such case,
so long as such Master Servicer Event of Default shall not have been remedied,
the Depositor or the Trustee may, and at the written direction of the Holders of
Certificates entitled to at least 51% of Voting Rights, the Trustee shall, by
notice in writing to the Master Servicer (and to the Depositor and the Trust
Administrator if given by the Trustee or to the Trustee and the Trust
Administrator if given by the Depositor), terminate all of the rights and
obligations of the Master Servicer in its capacity as a Master Servicer under
this Agreement, to the extent permitted by law, and in and to the Mortgage Loans
and the proceeds thereof. If a Master Servicer Event of Default described in
clause (vi) hereof shall occur, then so long as such Master Servicer Event of
Default shall not have been remedied during the applicable time period set forth
in clause (vi) above, the Trustee shall, by notice in writing to the Master
Servicer and the Depositor, terminate all of the rights and obligations of the
Master Servicer in its capacity as a Master Servicer under this Agreement and in
and to the Mortgage Loans and the proceeds thereof. On or after the receipt by
the Master Servicer of such written notice, all authority and power of the
Master Servicer under this Agreement, whether with respect to the Certificates
(other than as a Holder of any Certificate) or the Mortgage Loans or otherwise,
shall pass to and be vested in the Trust Administrator pursuant to and under
this Section and, without limitation, the Trust Administrator is hereby
authorized and empowered, as attorney-in-fact or otherwise, to execute and
deliver on behalf of and at the expense of the Master Servicer, any and all
documents and other instruments and to do or accomplish all other acts or things
necessary or appropriate to effect the purposes of such notice of termination,
whether to complete the transfer and endorsement or assignment of the Mortgage
Loans and related documents, or otherwise. The Master Servicer agrees, at its
sole cost and expense, promptly (and in any event no later than ten Business
Days subsequent to such notice) to provide the Trust Administrator with all
documents and records requested by it to enable it to assume the Master
Servicer's functions under this Agreement, and to cooperate with the Trust
Administrator and the Trustee in effecting the termination of the Master
Servicer's responsibilities and rights under this Agreement, including, without
limitation, the transfer within one Business Day to the Trust Administrator for
administration by it of all cash amounts which at the time shall be or should
have been credited by the Master Servicer to the Collection Account held by or
on behalf of the Master Servicer, the Distribution Account or any REO Account or
Servicing Account held by or on behalf of the Master Servicer or thereafter be
received with respect to the Mortgage Loans or any REO Property serviced by the
Master Servicer (provided, however, that the Master Servicer shall continue to
be entitled to receive all amounts accrued or owing to it under this

                                      110
<PAGE>

Agreement on or prior to the date of such termination, whether in respect of P&I
Advances or otherwise, and shall continue to be entitled to the benefits of
Section 6.03, notwithstanding any such termination, with respect to events
occurring prior to such termination). For purposes of this Section 7.01, each of
the Trustee and the Trust Administrator shall not be deemed to have knowledge of
a Master Servicer Event of Default unless a Responsible Officer of the Trustee
or the Trust Administrator, as applicable, assigned to and working in the
Trustee's or the Trust Administrator's, as the case may be, Corporate Trust
Office has actual knowledge thereof or unless written notice of any event which
is in fact such a Master Servicer Event of Default is received by the Trustee or
the Trust Administrator, as applicable, and such notice references the
Certificates, the Trust Fund or this Agreement.

                  SECTION 7.02. Trust Administrator or Trustee to Act;
                                Appointment of Successor.

                  (a) On and after the time the Master Servicer receives a
notice of termination, the Trust Administrator (and in the event the Trust
Administrator fails in its obligation, the Trustee) shall be the successor in
all respects to the Master Servicer in its capacity as Master Servicer under
this Agreement, the Master Servicer shall not have the right to withdraw any
funds from the Collection Account without the consent of the Trust Administrator
or the Trustee, as applicable, and the transactions set forth or provided for
herein and shall be subject to all the responsibilities, duties and liabilities
relating thereto and arising thereafter placed on the Master Servicer (except
for any representations or warranties of the Master Servicer under this
Agreement, the responsibilities, duties and liabilities contained in Section
2.03(c) and its obligation to deposit amounts in respect of losses pursuant to
Section 3.12) by the terms and provisions hereof including, without limitation,
the Master Servicer's obligations to make P&I Advances pursuant to Section 4.03;
provided, however, that if the Trust Administrator or the Trustee, as
applicable, is prohibited by law or regulation from obligating itself to make
advances regarding delinquent mortgage loans, then the Trust Administrator or
the Trustee, as applicable, shall not be obligated to make P&I Advances pursuant
to Section 4.03; and provided further, that any failure to perform such duties
or responsibilities caused by the Master Servicer's failure to provide
information required by Section 7.01 shall not be considered a default by the
Trust Administrator or the Trustee, as applicable, as successor to the Master
Servicer hereunder. As compensation therefor, the Trust Administrator or the
Trustee, as applicable, shall be entitled to the Servicing Fees and all funds
relating to the Mortgage Loans to which the Master Servicer would have been
entitled if it had continued to act hereunder (other than amounts which were due
or would become due to the Master Servicer prior to its termination or
resignation). Notwithstanding the above and subject to the next paragraph, the
Trust Administrator or the Trustee, as applicable, may, if it shall be unwilling
to so act, or shall, if it is unable to so act or if it is prohibited by law
from making advances regarding delinquent mortgage loans, or if the Holders of
Certificates entitled to at least 51% of the Voting Rights so request in writing
to the Trust Administrator or the Trustee, as applicable, promptly appoint or
petition a court of competent jurisdiction to appoint, an established mortgage
loan servicing institution acceptable to the Rating Agencies and having a net
worth of not less than $15,000,000 as the successor to the Master Servicer under
this Agreement in the assumption of all or any part of the responsibilities,
duties or liabilities of the Master Servicer under this Agreement. No
appointment of a successor to the Master Servicer under this Agreement shall be
effective until the assumption by the successor of all of the Master Servicer's
responsibilities, duties and liabilities hereunder. In connection with such
appointment and

                                      111
<PAGE>

assumption described herein, the Trust Administrator or the Trustee, as
applicable, may make such arrangements for the compensation of such successor
out of payments on Mortgage Loans as it and such successor shall agree;
provided, however, that no such compensation shall be in excess of that
permitted the Master Servicer as such hereunder. The Depositor, the Trust
Administrator, the Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
Pending appointment of a successor to the Master Servicer under this Agreement,
the Trust Administrator or the Trustee, as applicable, shall act in such
capacity as hereinabove provided.

                  Upon removal or resignation of the Master Servicer, the Trust
Administrator, with the cooperation of the Depositor, (x) shall solicit bids for
a successor Master Servicer as described below and (y) pending the appointment
of a successor Master Servicer as a result of soliciting such bids, shall serve
as Master Servicer of the Mortgage Loans serviced by such predecessor Master
Servicer. The Trust Administrator shall solicit, by public announcement, bids
from housing and home finance institutions, banks and mortgage servicing
institutions meeting the qualifications set forth above (including the Trust
Administrator or any affiliate thereof). Such public announcement shall specify
that the successor Master Servicer shall be entitled to the servicing
compensation agreed upon between the Trust Administrator, the successor Master
Servicer and the Depositor; provided, however, that no such fee shall exceed the
related Servicing Fee. Within thirty days after any such public announcement,
the Trust Administrator, with the cooperation of the Depositor, shall negotiate
in good faith and effect the sale, transfer and assignment of the servicing
rights and responsibilities hereunder to the qualified party submitting the
highest satisfactory bid as to the price they will pay to obtain such servicing.
The Trust Administrator upon receipt of the purchase price shall pay such
purchase price to the Master Servicer being so removed, after deducting from any
sum received by the Trust Administrator from the successor to the Master
Servicer in respect of such sale, transfer and assignment all costs and expenses
of any public announcement and of any sale, transfer and assignment of the
servicing rights and responsibilities reasonably incurred hereunder. After such
deductions, the remainder of such sum shall be paid by the Trust Administrator
to the Master Servicer at the time of such sale.

                  (b) If the Master Servicer fails to remit to the Trust
Administrator for distribution to the Certificateholders any payment required to
be made under the terms of the Certificates and this Agreement (for purposes of
this Section 7.02(b), a "Remittance") because the Master Servicer is the subject
of a proceeding under the federal Bankruptcy Code and the making of such
Remittance is prohibited by Section 362 of the federal Bankruptcy Code, the
Trustee (and in the event the Trustee fails in its obligation, the Trust
Administrator), shall upon notice of such prohibition, regardless of whether it
has received a notice of termination under Section 7.01, advance the amount of
such Remittance by depositing such amount in the Distribution Account on the
related Distribution Date. The Trust Administrator or the Trustee, as
applicable, shall be obligated to make such advance only if (i) such advance, in
the good faith judgment of the Trust Administrator or the Trustee, as
applicable, can reasonably be expected to be ultimately recoverable from Stayed
Funds and (ii) the Trust Administrator or the Trustee, as applicable, is not
prohibited by law from making such advance or obligating itself to do so. Upon
remittance of the Stayed Funds to the Trust Administrator or the Trustee, as
applicable, or the deposit thereof in the Distribution Account by a trustee in
bankruptcy or a federal bankruptcy court, the Trust Administrator or the
Trustee, as applicable, may recover the amount so advanced, without interest, by
withdrawing such amount from the Distribution Account;

                                      112
<PAGE>

however, nothing in this Agreement shall be deemed to affect the Trust
Administrator's or Trustee's, as applicable, rights to recover from the former
Master Servicer's bankruptcy estate interest on the amount of any such advance.
If the Trust Administrator or the Trustee, as the case may be, at any time makes
an advance under this Subsection which it later determines in its good faith
judgment will not be ultimately recoverable from the Stayed Funds with respect
to which such advance was made, the Trust Administrator or the Trustee, as
applicable, shall be entitled to reimburse itself for such advance, without
interest, by withdrawing from the Distribution Account, out of amounts on
deposit therein, an amount equal to the portion of such advance attributable to
the Stayed Funds.

                  SECTION 7.03. Notification to Certificateholders.

                  (a) Upon any termination of the Master Servicer pursuant to
Section 7.01 above or any appointment of a successor to the Master Servicer
pursuant to Section 7.02 above, the Trust Administrator shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register.

                  (b) Not later than the later of 60 days after the occurrence
of any event, which constitutes or which, with notice or lapse of time or both,
would constitute a Master Servicer Event of Default or five days after a
Responsible Officer of the Trustee or the Trust Administrator becomes aware of
the occurrence of such an event, the Trustee or the Trust Administrator shall
transmit (or in the case of the Trustee, the Trustee shall cause the Trust
Administrator to transmit) by mail to all Holders of Certificates notice of each
such occurrence, unless such default or Master Servicer Event of Default shall
have been cured or waived.

                  SECTION 7.04. Waiver of Master Servicer Events of Default.

                  Subject to Section 11.09(d), the Holders representing at least
66% of the Voting Rights evidenced by all Classes of Certificates affected by
any default or Master Servicer Event of Default hereunder may waive such default
or Master Servicer Event of Default; provided, however, that a default or Master
Servicer Event of Default under clause (i) or (vi) of Section 7.01 may be waived
only by all of the Holders of the Regular Certificates. Upon any such waiver of
a default or Master Servicer Event of Default, such default or Master Servicer
Event of Default shall cease to exist and shall be deemed to have been remedied
for every purpose hereunder. No such waiver shall extend to any subsequent or
other default or Master Servicer Event of Default or impair any right consequent
thereon except to the extent expressly so waived.

                                  ARTICLE VIII

               CONCERNING THE TRUSTEE AND THE TRUST ADMINISTRATOR

                  SECTION 8.01. Duties of Trustee and Trust Administrator

                  Each of the Trustee and the Trust Administrator, prior to the
occurrence of a Master Servicer Event of Default and after the curing of all
Master Servicer Events of Default which may have occurred, undertakes to perform
such duties and only such duties as are specifically set forth in this
Agreement. During a Master Servicer Event of Default, each of the Trustee and
the Trust Administrator shall exercise such of the rights and powers vested in
it by this Agreement, and use the same degree of care and skill in their
exercise as a prudent person would exercise or use under the circumstances in
the conduct of such person's own affairs. Any permissive right of the Trustee or
the Trust Administrator enumerated in this Agreement shall not be construed as a
duty.

                  Each of the Trustee and the Trust Administrator, upon receipt
of all resolutions, certificates, statements, opinions, reports, documents,
orders or other instruments furnished to it, which are specifically required to
be furnished pursuant to any provision of this Agreement, shall examine them to
determine whether they conform to the requirements of this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, it shall take such action as it deems appropriate to have the
instrument corrected, and if the instrument is not corrected to its
satisfaction, it will provide notice thereof to the Certificateholders.

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

                  (i) Prior to the occurrence of a Master Servicer Event of
         Default, and after the curing of all such Master Servicer Events of
         Default which may have occurred, the duties and obligations of each of
         the Trustee and the Trust Administrator shall be determined solely by
         the express provisions of this Agreement, neither the Trustee nor the
         Trust Administrator shall be liable except for the performance of such
         duties and obligations as are specifically set forth in this Agreement,
         no implied covenants or obligations shall be read into this Agreement
         against the Trustee or the Trust Administrator and, in the absence of
         bad faith on the part of the Trustee or the Trust Administrator, as
         applicable, the Trustee or the Trust Administrator, as the case may be,
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon any certificates or
         opinions furnished to the Trustee or the Trust Administrator, as the
         case may be, that conform to the requirements of this Agreement;

                  (ii) Neither the Trustee nor the Trust Administrator shall be
         personally liable for an error of judgment made in good faith by a
         Responsible Officer or Responsible Officers of it unless it shall be
         proved that it was negligent in ascertaining the pertinent facts; and

                  (iii) Neither the Trustee nor the Trust Administrator shall be
         personally liable with respect to any action taken, suffered or omitted
         to be taken by it in good faith in accordance

                                      114

         with the direction of the Holders of Certificates entitled to at least
         25% of the Voting Rights relating to the time, method and place of
         conducting any proceeding for any remedy available to it or exercising
         any trust or power conferred upon it under this Agreement.

                  SECTION 8.02. Certain Matters Affecting the Trustee and the
                                Trust Administrator.

                  (a) Except as otherwise provided in Section 8.01:

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

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

                           (iii) Neither the Trustee nor the Trust Administrator
                  shall be under any obligation to exercise any of the trusts or
                  powers vested in it by this Agreement or to institute, conduct
                  or defend any litigation hereunder or in relation hereto at
                  the request, order or direction of any of the
                  Certificateholders, pursuant to the provisions of this
                  Agreement, unless such Certificateholders shall have offered
                  to the Trustee or the Trust Administrator, as applicable,
                  reasonable security or indemnity against the costs, expenses
                  and liabilities which may be incurred therein or thereby;
                  nothing contained herein shall, however, relieve the Trustee
                  or the Trust Administrator of the obligation, upon the
                  occurrence of a Master Servicer Event of Default (which has
                  not been cured or waived), to exercise such of the rights and
                  powers vested in it by this Agreement, and to use the same
                  degree of care and skill in their exercise as a prudent person
                  would exercise or use under the circumstances in the conduct
                  of such person's own affairs;

                           (iv) Neither the Trustee nor the Trust Administrator
                  shall be personally liable for any action taken, suffered or
                  omitted by it in good faith and believed by it to be
                  authorized or within the discretion or rights or powers
                  conferred upon it by this Agreement;

                           (v) Prior to the occurrence of a Master Servicer
                  Event of Default hereunder and after the curing of all Master
                  Servicer Events of Default which may have occurred, neither
                  the Trustee nor the Trust Administrator shall be bound to make
                  any investigation into the facts or matters stated in any
                  resolution, certificate, statement, instrument, opinion,
                  report, notice, request, consent, order, approval, bond or
                  other paper or document, unless requested in writing to do so
                  by the Holders of

                                      115

                  Certificates entitled to at least 25% of the Voting Rights;
                  provided, however, that if the payment within a reasonable
                  time to the Trustee or the Trust Administrator, as applicable,
                  of the costs, expenses or liabilities likely to be incurred by
                  it in the making of such investigation is, in the opinion of
                  the Trustee or the Trust Administrator, as applicable, not
                  reasonably assured to the Trustee or Trust Administrator, as
                  applicable, by such Certificateholders, the Trustee or the
                  Trust Administrator, as applicable, may require reasonable
                  indemnity against such expense, or liability from such
                  Certificateholders as a condition to taking any such action;

                           (vi) Each of the Trustee and the Trust Administrator
                  may execute any of the trusts or powers hereunder or perform
                  any duties hereunder either directly or by or through agents
                  or attorneys; and

                           (vii) Neither the Trustee nor the Trust Administrator
                  shall be personally liable for any loss resulting from the
                  investment of funds held in the Collection Account at the
                  direction of the Master Servicer pursuant to Section 3.12.

                  (b) All rights of action under this Agreement or under any of
the Certificates, enforceable by the Trustee or the Trust Administrator, may be
enforced by it without the possession of any of the Certificates, or the
production thereof at the trial or other proceeding relating thereto, and any
such suit, action or proceeding instituted by the Trustee or the Trust
Administrator shall be brought in its name for the benefit of all the Holders of
such Certificates, subject to the provisions of this Agreement.

                  SECTION 8.03. Neither the Trustee nor Trust Administrator
                                Liable for Certificates or Mortgage Loans.

                  The recitals contained herein and in the Certificates (other
than the signature of the Trustee or the Trust Administrator, on behalf of the
Trustee, the authentication of the Trustee or the Trust Administrator on the
Certificates, the acknowledgments of the Trustee and the Trust Administrator
contained in Article II and the representations and warranties of the Trustee
and the Trust Administrator in Section 8.12) shall be taken as the statements of
the Depositor and neither the Trustee nor the Trust Administrator assumes any
responsibility for their correctness. Neither the Trustee nor the Trust
Administrator makes any representations or warranties as to the validity or
sufficiency of this Agreement (other than as specifically set forth in Section
8.12) or of the Certificates (other than the signature of the Trust
Administrator, and authentication of the Trust Administrator on the
Certificates) or of any Mortgage Loan or related document. Neither the Trustee
nor the Trust Administrator shall be accountable for the use or application by
the Depositor of any of the Certificates or of the proceeds of such
Certificates, or for the use or application of any funds paid to the Depositor
or the Master Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Master Servicer, other than any
funds held by or on behalf of the Trustee or the Trust Administrator in
accordance with Section 3.10.

                  Each of the Trustee and the Trust Administrator in its
individual capacity or any other capacity may become the owner or pledgee of
Certificates with the same rights it would have if it were not Trustee or Trust
Administrator, as applicable.

                  SECTION 8.05. Trustee's and Trust Administrator's Fees and
                                Expenses.

                  (a) The Trust Administrator shall withdraw from the
Distribution Account on each Distribution Date and pay to itself any income and
gain realized from the investment of funds deposited in the Distribution Account
and pay to the Trustee its portion of such income and gain. Each of the Trustee
and the Trust Administrator and any director, officer, employee or agent of the
Trustee or the Trust Administrator, as applicable, shall be indemnified by the
Trust Fund and held harmless against any loss, liability or expense (not
including expenses, disbursements and advances incurred or made by the Trustee
or the Trust Administrator, as applicable, including the compensation and the
expenses and disbursements of its agents and counsel, in the ordinary course of
the Trustee's or Trust Administrator's, as the case may be, performance in
accordance with the provisions of this Agreement) incurred by the Trustee or the
Trust Administrator, as applicable, in connection with any claim or legal action
or any pending or threatened claim or legal action arising out of or in
connection with the acceptance or administration of its obligations and duties
under this Agreement, other than any loss, liability or expense (i) resulting
from any breach of the Master Servicer's obligations in connection with this
Agreement for which the Master Servicer shall indemnify the Trustee and the
Trust Administrator pursuant to Section 10.03(b) (and in the case of the
Trustee, resulting from any breach of the Trust Administrator's obligations in
connection with this Agreement for which the Trust Administrator shall indemnify
the Trustee pursuant to Section 10.03(a) and in the case of the Trust
Administrator, resulting from any breach of the Trustee's obligations in
connection with this Agreement for which the Trustee shall indemnify the Trust
Administrator pursuant to Section 10.03(c)), (ii) that constitutes a specific
liability of the Trustee or the Trust Administrator, as applicable, pursuant to
Section 10.01(g) or (iii) any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties hereunder
or in the case of the Trust Administrator, as a result of a breach of the Trust
Administrator's obligations under Article X hereof. The Master Servicer agrees
to indemnify the Trustee and the Trust Administrator, from, and hold it harmless
against, any loss, liability or expense arising in respect of any breach by the
Master Servicer of its obligations in connection with this Agreement. Such
indemnity shall survive the termination or discharge of this Agreement and the
resignation or removal of the Trustee or the Trust Administrator, as the case
may be. Any payment hereunder made by the Master Servicer to the Trustee or the
Trust Administrator shall be from the Master Servicer's own funds, without
reimbursement from Any Trust REMIC therefor.

                  (b) The Depositor shall pay any annual rating agency fees of
the Rating Agencies for ongoing surveillance from its own funds without right of
reimbursement.

                  SECTION 8.06. Eligibility Requirements for Trustee and Trust
                                Administrator.

                  Each of the Trustee and the Trust Administrator hereunder
shall at all times be a corporation or an association (other than the Depositor,
the Sellers, the Master Servicer or, in the case of the Trustee, any Affiliate
of the foregoing) organized and doing business under the laws of

                                      117
<PAGE>

any state or the United States of America, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000 (or a member of a bank holding company whose capital and
surplus is at least $50,000,000) and subject to supervision or examination by
federal or state authority. If such corporation or association publishes reports
of conditions at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of conditions so published. In case at any time the Trustee or the
Trust Administrator shall cease to be eligible in accordance with the provisions
of this Section, the Trustee or the Trust Administrator, as the case may be,
shall resign immediately in the manner and with the effect specified in Section
8.07.

                  SECTION 8.07. Resignation and Removal of the Trustee and the
                                Trust Administrator

                  Either the Trustee or the Trust Administrator may at any time
resign and be discharged from the trust hereby created by giving written notice
thereof to the Depositor, the Master Servicer, to the Certificateholders and, if
the Trustee is resigning, to the Trust Administrator, or, if the Trust
Administrator is resigning, to the Trustee. Upon receiving such notice of
resignation, the Depositor shall promptly appoint a successor Trustee or Trust
Administrator (which may be the same Person in the event both the Trustee and
the Trust Administrator resign or are removed) by written instrument, in
duplicate, which instrument shall be delivered to the resigning Trustee or Trust
Administrator and to the successor Trustee or Trust Administrator, as
applicable. A copy of such instrument shall be delivered to the
Certificateholders, the Trustee or Trust Administrator, as applicable, and the
Master Servicer by the Depositor. If no successor Trustee or Trust Administrator
shall have been so appointed and have accepted appointment within 30 days after
the giving of such notice of resignation, the resigning Trustee or Trust
Administrator, as applicable, may petition any court of competent jurisdiction
for the appointment of a successor Trustee or Trust Administrator, as
applicable.

                  If at any time the Trustee or the Trust Administrator shall
cease to be eligible in accordance with the provisions of Section 8.06 and shall
fail to resign after written request therefor by the Depositor (or in the case
of the Trust Administrator, the Trustee), or if at any time the Trustee or the
Trust Administrator shall become incapable of acting, or shall be adjudged
bankrupt or insolvent, or a receiver of the Trustee or the Trust Administrator
or of its property shall be appointed, or any public officer shall take charge
or control of the Trustee or the Trust Administrator of its property or affairs
for the purpose of rehabilitation, conservation or liquidation, then the
Depositor (or in the case of the Trust Administrator, the Trustee) may remove
the Trustee or the Trust Administrator, as applicable, and appoint a successor
Trustee or Trust Administrator (which may be the same Person in the event both
the Trustee and the Trust Administrator resign or are removed) by written
instrument, in duplicate, which instrument shall be delivered to the Trustee or
Trust Administrator, as the case may be, so removed and to the successor Trustee
or Trust Administrator. A copy of such instrument shall be delivered to the
Certificateholders, the Trustee or the Trust Administrator, as applicable, and
the Master Servicer by the Depositor.

<PAGE>

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights may at any time remove the Trustee or the Trust Administrator and
appoint a successor Trustee or Trust Administrator by written instrument or
instruments, in triplicate, signed by such Holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Depositor, one complete set to the Trustee or to the Trust Administrator, as the
case may be, so removed and one complete set to the successor so appointed. A
copy of such instrument shall be delivered to the Certificateholders and the
Master Servicer by the Depositor. In addition, if the Trustee has knowledge that
the Trust Administrator has breached any of its duties under this Agreement, the
Trustee may remove the Trust Administrator in the same manner as provided in the
prior sentence. For purposes of this Section, the Trustee shall not be deemed to
have knowledge of a breach by the Trust Administrator of any of its duties
hereunder, unless a Responsible Officer of the Trustee , assigned to and working
in the Trustee's Corporate Trust Office has actual knowledge thereof or unless
written notice of any event which is in fact such a breach is received by the
Trustee, and such notice references the Certificates, the Trust Fund or this
Agreement.

                  Any resignation or removal of the Trustee or the Trust
Administrator and appointment of a successor Trustee or Trust Administrator, as
the case may be, pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor Trustee or
Trust Administrator as provided in Section 8.08. Notwithstanding the foregoing,
in the event the Trust Administrator advises the Trustee that it is unable to
continue to perform its obligations pursuant to the terms of this Agreement
prior to the appointment of a successor, the Trustee shall be obligated to
perform such obligations until a new Trust Administrator is appointed. Such
performance shall be without prejudice to any claim by a party hereto or
beneficiary hereof resulting from the Trust Administrator's breach of its
obligations hereunder.

                  SECTION 8.08. Successor Trustee or Trust Administrator

                  Any successor Trustee or Trust Administrator appointed as
provided in Section 8.07 shall execute, acknowledge and deliver to the
Depositor, the Trustee or the Trust Administrator, as applicable, and its
predecessor Trustee or Trust Administrator an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee or Trust Administrator shall become effective and such
successor Trustee or Trust Administrator, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as Trustee or Trust Administrator herein. The predecessor Trustee or Trust
Administrator shall deliver to the successor Trustee or Trust Administrator all
Mortgage Files and related documents and statements to the extent held by it
hereunder, as well as all moneys, held by it hereunder, and the Depositor and
the predecessor Trustee or Trust Administrator shall execute and deliver such
instruments and do such other things as may reasonably be required for more
fully and certainly vesting and confirming in the successor Trustee or Trust
Administrator all such rights, powers, duties and obligations.

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

                  Upon acceptance of appointment by a successor Trustee or Trust
Administrator as provided in this Section, the Depositor shall mail notice of
the succession of such Trustee or Trust Administrator hereunder to all Holders
of Certificates at their addresses as shown in the Certificate Register. If the
Depositor fails to mail such notice within 10 days after acceptance of
appointment by the successor Trustee or Trust Administrator, the successor
Trustee or Trust Administrator shall cause such notice to be mailed at the
expense of the Depositor.

                  SECTION 8.09. Merger or Consolidation of Trustee.

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

                  SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

                  Notwithstanding any other provisions hereof, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of REMIC I or property securing the same may at the time be located, the
Trustee shall have the power and shall execute and deliver all instruments to
appoint one or more Persons approved by the Trustee to act as co-trustee or co-
trustees, jointly with the Trustee, or separate trustee or separate trustees, of
all or any part of REMIC I, and to vest in such Person or Persons, in such
capacity, such title to REMIC I, or any part thereof, and, subject to the other
provisions of this Section 8.10, such powers, duties, obligations, rights and
trusts as the Trustee may consider necessary or desirable. No co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility as
a successor trustee under Section 8.06 hereunder and no notice to Holders of
Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be
required under Section 8.08 hereof.

                  In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 8.10 all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed by the Trustee (whether as
Trustee hereunder or as successor to a defaulting Master Servicer hereunder),
the Trustee shall be incompetent or unqualified to perform such act or acts, in
which event such rights, powers, duties and obligations (including the holding
of title to REMIC I or any portion thereof in any such jurisdiction) shall be
exercised and performed by such separate trustee or co-trustee at the direction
of the Trustee.

                  Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the

                                      120
<PAGE>

conditions of this Article VIII. Each separate trustee and co-trustee, upon its
acceptance of the trust conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Trustee, or
separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of, or affording protection to, the
Trustee. Every such instrument shall be filed with the Trustee.

                  Any separate trustee or co-trustee may, at any time,
constitute the Trustee, its agent or attorney-in-fact, with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Agreement on its behalf and in its name. If any separate trustee
or co-trustee shall die, become incapable of acting, resign or be removed, all
of its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee or co-trustee.

                  SECTION 8.11. Appointment of Office or Agency.

                  The Trust Administrator hereby appoints its Corporate Trust
Office as the office or agency in the City of New York, New York where the
Certificates may be surrendered for registration of transfer or exchange, and
presented for final distribution, and where notices and demands to or upon the
Trust Administrator in respect of the Certificates and this Agreement may be
served.

                  SECTION 8.12. Representations and Warranties.

                  Each of the Trustee and the Trust Administrator hereby
represents and warrants to the Master Servicer, the Depositor and the Trustee or
the Trust Administrator, as applicable, as of the Closing Date, that:

                  (i) It is a national banking association duly organized,
         validly existing and in good standing under the laws of the United
         States of America.

                  (ii) The execution and delivery of this Agreement by it, and
         the performance and compliance with the terms of this Agreement by it,
         will not violate its articles of association or bylaws or constitute a
         default (or an event which, with notice or lapse of time, or both,
         would constitute a default) under, or result in the breach of, any
         material agreement or other instrument to which it is a party or which
         is applicable to it or any of its assets.

                  (iii) It has the full power and authority to enter into and
         consummate all transactions contemplated by this Agreement, has duly
         authorized the execution, delivery and performance of this Agreement,
         and has duly executed and delivered this Agreement.

                  (iv) This Agreement, assuming due authorization, execution and
         delivery by the other parties hereto, constitutes a valid, legal and
         binding obligation of it, enforceable against it in accordance with the
         terms hereof, subject to (A) applicable bankruptcy, insolvency,
         receivership, reorganization, moratorium and other laws affecting the
         enforcement of

                                      121
<PAGE>

         creditors' rights generally, and (B) general principles of equity,
         regardless of whether such enforcement is considered in a proceeding in
         equity or at law.

                  (v) It is not in violation of, and its execution and delivery
         of this Agreement and its performance and compliance with the terms of
         this Agreement will not constitute a violation of, any law, any order
         or decree of any court or arbiter, or any order, regulation or demand
         of any federal, state or local governmental or regulatory authority,
         which violation, in its good faith and reasonable judgment, is likely
         to affect materially and adversely either the ability of it to perform
         its obligations under this Agreement or its financial condition.

                  (vi) No litigation is pending or, to the best of its
         knowledge, threatened against it, which would prohibit it from entering
         into this Agreement or, in its good faith reasonable judgment, is
         likely to materially and adversely affect either the ability of it to
         perform its obligations under this Agreement or its financial
         condition.

                                   ARTICLE IX

                                   TERMINATION

                  SECTION 9.01 Termination Upon Repurchase or Liquidation of the
                               Trust Fund.

                  (a) Subject to Section 9.02, the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Trustee and the Trust Administrator with respect to the Mortgage Loans (other
than the obligations of the Master Servicer to provide for and the Trust
Administrator to make payments to the Holders of the related Class(es) of the
Certificates as hereinafter set forth) shall terminate upon payment to the
Certificateholders and the deposit of all amounts held by or on behalf of the
Trustee and required hereunder to be so paid or deposited on the Distribution
Date coinciding with or following the earlier to occur of (i) the purchase by
the Master Servicer of all Mortgage Loans and each REO Property remaining in
REMIC I and (ii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in REMIC I;
provided, however, that in no event shall the trust created hereby continue
beyond the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof. The purchase by the Master
Servicer of all Mortgage Loans and each REO Property remaining in REMIC I shall
be at a price (the "Termination Price") equal to the greater of (A) the
aggregate Purchase Price of all the Mortgage Loans included in REMIC I, plus the
appraised value of each REO Property, if any, included in REMIC I, such
appraisal to be conducted by an appraiser mutually agreed upon by the Master
Servicer and the Trust Administrator in their reasonable discretion and (B) the
aggregate fair market value of all of the assets in REMIC I (as determined by
the Master Servicer, with the consent of the Trustee, as of the close of
business on the third Business Day next preceding the date upon which notice of
any such termination is furnished to Certificateholders pursuant to the third
paragraph of this Section 9.01).

                  (b) The Master Servicer shall have the right to purchase all
of the Mortgage Loans and each REO Property remaining in REMIC I pursuant to
clause (i) of the preceding paragraph no later than the Determination Date in
the month immediately preceding the Distribution Date on which the Certificates
will be retired; provided, however, that the Master Servicer, as provided above,
may elect to purchase all of the Mortgage Loans and each REO Property remaining
in REMIC I pursuant to clause (i) above only if the aggregate Stated Principal
Balance of the Mortgage Loans and each REO Property remaining in the Trust Fund
at the time of such election is reduced to less than 5% of the aggregate Stated
Principal Balance of the Mortgage Loans at the Cut-off Date. For federal income
tax purposes, the purchase by the Master Servicer of all Mortgage Loans and all
REO Properties underlying the Certificates is intended to facilitate a
redemption of such Certificates pursuant to a "cleanup call" within the meaning
of Treasury regulation section 1.860G-2(j). Notwithstanding the foregoing, the
Master Servicer shall have the right to transfer, sell or assign its rights to
purchase all of the Mortgage Loans and each REO Property remaining in REMIC I.
For so long as the Master Servicer is affiliated with an entity subject to
regulation by the Office of the Comptroller of the Currency; the FDIC, the
Federal Reserve or the OTS, the Master Servicer may exercise the foregoing
option only if the aggregate fair market value of the Mortgage Loans and any

                                      123
<PAGE>

properties acquired in respect thereof is greater than or equal to the purchase
price described in the preceding paragraph.

                  (c) Notice of the liquidation of the Certificates shall be
given promptly by the Trust Administrator by letter to Certificateholders mailed
(a) in the event such notice is given in connection with the purchase of the
Mortgage Loans and each REO Property remaining in REMIC I by the Master
Servicer, not earlier than the 15th day and not later than the 25th day of the
month next preceding the month of the final distribution on the Certificates or
(b) otherwise during the month of such final distribution on or before the
Determination Date in such month, in each case specifying (i) the Distribution
Date upon which the Trust Fund will terminate and final payment of the
Certificates will be made upon presentation and surrender of the Certificates at
the office of the Trust Administrator therein designated, (ii) the amount of any
such final payment, (iii) that no interest shall accrue in respect of the
Certificates from and after the Interest Accrual Period relating to the final
Distribution Date therefor and (iv) that the Record Date otherwise applicable to
such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office of the Trust
Administrator. In the event such notice is given in connection with the purchase
of all of the Mortgage Loans and each REO Property remaining in REMIC I by the
Master Servicer, the Master Servicer shall deliver to the Trust Administrator
for deposit in the Distribution Account not later than the last Business Day of
the month next preceding the month in which such distribution will be made an
amount in immediately available funds equal to the Termination Price. Upon
certification to the Trust Administrator by a Servicing Officer of the making of
such final deposit, the Trustee shall promptly release or cause to be released
to the Master Servicer the Mortgage Files for the remaining Mortgage Loans, and
the Trustee shall execute all assignments, endorsements and other instruments
delivered to it which are necessary to effectuate such transfer.

                  (d) Upon presentation of the Certificates by the
Certificateholders on the final Distribution Date, the Trust Administrator shall
distribute to each Certificateholder so presenting and surrendering its
Certificates the amount otherwise distributable on such Distribution Date in
accordance with Section 4.01 in respect of the Certificates so presented and
surrendered. Any funds not distributed to any Holder or Holders of Certificates
being retired on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
in trust by the Trust Administrator and credited to the account of the
appropriate non-tendering Holder or Holders. If any Certificates as to which
notice has been given pursuant to this Section 9.01 shall not have been
surrendered for cancellation within six months after the time specified in such
notice, the Trust Administrator shall mail a second notice to the remaining non-
tendering Certificateholders to surrender their Certificates for cancellation in
order to receive the final distribution with respect thereto. If within one year
after the second notice all such Certificates shall not have been surrendered
for cancellation, the Trust Administrator shall, directly or through an agent,
mail a final notice to remaining related non-tendering Certificateholders
concerning surrender of their Certificates. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets remaining in the trust funds. If within one year after
the final notice any such Certificates shall not have been surrendered for
cancellation, the Trust Administrator shall pay to the Class R
Certificateholders all such amounts, and all rights of non-tendering
Certificateholders in or to such amounts shall thereupon cease. No interest
shall accrue or be payable to any Certificateholder on any amount held in trust
by the Trust

                                      124
<PAGE>

Administrator as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section 9.01.

                  Immediately following the deposit of funds in trust hereunder
in respect of the Certificates, the Trust Fund shall terminate.

                  SECTION 9.02 Additional Termination Requirements.

                  (a) In the event that the Master Servicer purchases all the
Mortgage Loans and each REO Property, the Trust Fund shall be terminated in
accordance with the following additional requirements (or in connection with the
final payment on or other liquidation of the last Mortgage Loan or REO Property
remaining in REMIC I, the additional requirement specified in clause (i) below):

                           (i) The Trust Administrator shall specify the first
                  day in the 90-day liquidation period in a statement attached
                  to REMIC I's final Tax Return pursuant to Treasury regulation
                  Section 1.860F-1, and such termination shall satisfy all
                  requirements of a qualified liquidation under Section 860F of
                  the Code and any regulations thereunder, as evidenced by an
                  Opinion of Counsel obtained at the expense of the Master
                  Servicer;

                           (ii) During such 90-day liquidation period, and at or
                  prior to the time of making of the final payment on the
                  Certificates, the Trustee shall sell all of the assets of
                  REMIC I to the Master Servicer for cash; and

                           (iii) At the time of the making of the final payment
                  on the Certificates, the Trust Administrator shall distribute
                  or credit, or cause to be distributed or credited, to the
                  Holders of the Residual Certificates all cash on hand in REMIC
                  I (other than cash retained to meet claims), and the Trust
                  Fund shall terminate at that time.

                  (b) At the expense of the Master Servicer (or in the event of
termination under Section 9.01(a)(ii), at the expense of the Trust
Administrator), the Trust Administrator shall prepare or cause to be prepared
the documentation required in connection with the adoption of a plan of
liquidation of each Trust REMIC pursuant to this Section 9.02.

                  (c) By their acceptance of Certificates, the Holders thereof
hereby agree to authorize the Trust Administrator to specify the 90-day
liquidation period for each Trust REMIC, which authorization shall be binding
upon all successor Certificateholders.

                                REMIC PROVISIONS

                  SECTION 10.01. REMIC Administration.

                  (a) The Trust Administrator shall elect to treat each Trust
REMIC as a REMIC under the Code and, if necessary, under applicable state law.
Such election will be made by the Trust Administrator on Form 1066 or other
appropriate federal tax or information return or any appropriate state return
for the taxable year ending on the last day of the calendar year in which the
Certificates are issued. For the purposes of the REMIC elections in respect of
each Trust REMIC, the REMIC I Regular Interest shall be designated as the
Regular Interest in REMIC I, the Class R-I Interest shall be designated as the
sole class of Residual Interests in REMIC I, the Certificates (other than the
Class R Certificates) shall be designated as the Regular Interests in REMIC II
and the Class R-II Interest shall be designated as the sole class of Residual
Interests in REMIC II. Neither the Trustee nor the Trust Administrator shall
permit the creation of any "interests" in any Trust REMIC (within the meaning of
Section 860G of the Code) other than the Certificates and the interests
represented by the Certificates.

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

                  (c) The Trust Administrator shall pay out of its own funds,
without any right of reimbursement, any and all expenses relating to any tax
audit of the Trust Fund (including, but not limited to, any professional fees or
any administrative or judicial proceedings with respect to any Trust REMIC that
involve the Internal Revenue Service or state tax authorities), other than the
expense of obtaining any tax related Opinion of Counsel except as specified
herein. The Trust Administrator, as agent for each Trust REMIC's tax matters
person, shall (i) act on behalf of the Trust Fund in relation to any tax matter
or controversy involving any Trust REMIC and (ii) represent the Trust Fund in
any administrative or judicial proceeding relating to an examination or audit by
any governmental taxing authority with respect thereto. The holder of the
largest Percentage Interest of the Residual Certificates shall be designated, in
the manner provided under Treasury regulations section 1.860F-4(d) and Treasury
regulations section 301.6231(a)(7)-1, as the tax matters person of any Trust
REMIC created hereunder. By its acceptance thereof, the holder of the largest
Percentage Interest of the Residual Certificates hereby agrees to irrevocably
appoint the Trust Administrator or an Affiliate as its agent to perform all of
the duties of the tax matters person for the Trust Fund.

                  (d) The Trust Administrator shall prepare, the Trustee shall
sign, and the Trust Administrator shall file, all of the Tax Returns in respect
of any Trust REMIC created hereunder. The expenses of preparing and filing such
returns shall be borne by the Trust Administrator without any right of
reimbursement therefor. The Master Servicer shall provide on a timely basis to
the Trust Administrator or its designee such information with respect to the
assets of the Trust Fund as is in its possession and reasonably required by the
Trust Administrator to enable it to perform its obligations under this Article.

                                      126
<PAGE>

                  (e) The Trust Administrator shall perform on behalf of any
Trust REMIC all reporting and other tax compliance duties that are the
responsibility of any Trust REMIC under the Code, the REMIC Provisions or other
compliance guidance issued by the Internal Revenue Service or any state or local
taxing authority including the filing of Form 8811 with the Internal Revenue
Service within 30 days following the Closing Date. Among its other duties, as
required by the Code, the REMIC Provisions or other such compliance guidance,
the Trust Administrator shall provide (i) to any Transferor of a Residual
Certificate such information as is necessary for the application of any tax
relating to the transfer of a Residual Certificate to any Person who is not a
Permitted Transferee, (ii) to the Certificateholders such information or reports
as are required by the Code or the REMIC Provisions including reports relating
to interest, original issue discount and market discount or premium (using the
Prepayment Assumption as required) and (iii) to the Internal Revenue Service the
name, title, address and telephone number of the person who will serve as the
representative of REMIC I. The Master Servicer shall provide on a timely basis
to the Trust Administrator such information with respect to the assets of the
Trust Fund, including, without limitation, the Mortgage Loans, as is in its
possession and reasonably required by the Trust Administrator to enable it to
perform its obligations under this subsection. In addition, the Depositor shall
provide or cause to be provided to the Trust Administrator, within ten (10) days
after the Closing Date, all information or data that the Trust Administrator
reasonably determines to be relevant for tax purposes as to the valuations and
issue prices of the Certificates, including, without limitation, the price,
yield, prepayment assumption and projected cash flow of the Certificates.

                  (f) The Master Servicer, the Trustee and the Trust
Administrator shall take such action and shall cause each Trust REMIC to take
such action as shall be necessary to create or maintain the status thereof as a
REMIC under the REMIC Provisions. The Master Servicer, the Trustee and the Trust
Administrator shall not take any action, cause the Trust Fund to take any action
or fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of each Trust REMIC as a REMIC or (ii) result in the imposition of a tax
upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) (either such
event, an "Adverse REMIC Event") unless the Trustee and the Trust Administrator
have received an Opinion of Counsel, addressed to the Trustee and the Trust
Administrator (at the expense of the party seeking to take such action but in no
event at the expense of the Trust Administrator or the Trustee) to the effect
that the contemplated action will not, with respect to each Trust REMIC,
endanger such status or result in the imposition of such a tax, nor shall the
Master Servicer take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee or the Trust Administrator has advised it in
writing that it has received an Opinion of Counsel to the effect that an Adverse
REMIC Event could occur with respect to such action. In addition, prior to
taking any action with respect to each Trust REMIC or its assets, or causing
REMIC I to take any action, which is not contemplated under the terms of this
Agreement, the Master Servicer will consult with the Trustee and the Trust
Administrator or their designee, in writing, with respect to whether such action
could cause an Adverse REMIC Event to occur with respect to each Trust REMIC,
and the Master Servicer shall not take any such action or cause any Trust REMIC
to take any such action as to which the Trustee or the Trust Administrator has
advised it in writing that an Adverse REMIC Event could occur. The Trust
Administrator and the Trustee may consult with counsel to make such written
advice, and the cost of same shall be borne by the party seeking to take the
action not permitted by this Agreement,

                                      127
<PAGE>

but in no event shall such cost be an expense of the Trustee or the Trust
Administrator. At all times as may be required by the Code, the Trust
Administrator, the Trustee or the Master Servicer will ensure that substantially
all of the assets of each Trust REMIC will consist of "qualified mortgages" as
defined in Section 860G(a)(3) of the Code and "permitted investments" as defined
in Section 860G(a)(5) of the Code.

                  (g) In the event that any tax is imposed on "prohibited
transactions" of any Trust REMIC created hereunder as defined in Section
860F(a)(2) of the Code, on the "net income from foreclosure property" of any
Trust REMIC as defined in Section 860G(c) of the Code, on any contributions to
any Trust REMIC after the Startup Day therefor pursuant to Section 860G(d) of
the Code, or any other tax is imposed by the Code or any applicable provisions
of state or local tax laws, such tax shall be charged (i) to the Trust
Administrator pursuant to Section 10.03 hereof, if such tax arises out of or
results from a breach by the Trust Administrator of any of its obligations under

any tax under the REMIC Provisions or other applicable provisions of federal,
state and local law or ordinances.

                  (k) None of the Trustee, the Trust Administrator or the Master

expense of the Trustee or the Trust Administrator) that such sale, disposition,
substitution, acquisition or contribution will not (a) affect adversely the

                  SECTION 10.03. Master Servicer and Trust Administrator

                            MISCELLANEOUS PROVISIONS

                  SECTION 11.01. Amendment.

                  This Agreement may be amended from time to time by the
Depositor, the Master Servicer, the Trustee and the Trust Administrator without
the consent of any of the Certificateholders, (i) to cure any ambiguity or
defect, (ii) to correct, modify or supplement any provisions herein (including
to give effect to the expectations of Certificateholders) or (iii) to make any
other provisions with respect to matters or questions arising under this
Agreement which shall not be inconsistent with the provisions of this Agreement,
provided that such action shall not, as evidenced by either (a) an Opinion of
Counsel delivered to the Trustee and the Trust Administrator or (b) written
notice to the Depositor, the Master Servicer, the Trust Administrator and the
Trustee from the Rating Agencies that such action will not result in the
reduction or withdrawal of the rating of any outstanding Class of Certificates
with respect to which it is a Rating Agency, adversely affect in any material
respect the interests of any Certificateholder. No amendment shall be deemed to
adversely affect in any material respect the interests of any Certificateholder
who shall have consented thereto, and no Opinion of Counsel or written notice
from the Rating Agencies shall be required to address the effect of any such
amendment on any such consenting Certificateholder.

                  This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Trust Administrator and the Trustee with the
consent of the Holders of Certificates entitled to at least 66% of the Voting
Rights for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments received on Mortgage Loans which are required to be distributed on
any Certificate without the consent of the Holder of such Certificate, (ii)
adversely affect in any material respect the interests of the Holders of any
Class of Certificates in a manner, other than as described in (i), without the
consent of the Holders of Certificates of such Class evidencing at least 66% of
the Voting Rights allocated to such Class, or (iii) modify the consents required
by the immediately preceding clauses (i) and (ii) without the consent of the
Holders of all Certificates then outstanding. Notwithstanding any other
provision of this Agreement, for purposes of the giving or withholding of
consents pursuant to this Section 11.01, Certificates registered in the name of
the Depositor or the Master Servicer or any Affiliate thereof shall be entitled
to Voting Rights with respect to matters affecting such Certificates.

                  Notwithstanding any contrary provision of this Agreement,
neither the Trustee nor the Trust Administrator shall consent to any amendment
to this Agreement unless it shall have first received an Opinion of Counsel to
the effect that such amendment will not result in the imposition of any tax on
any Trust REMIC pursuant to the REMIC Provisions or cause any Trust REMIC to
fail to qualify as a REMIC at any time that any Certificates are outstanding.

                  Prior to executing any amendment pursuant to this Section, the
Trustee and the Trust Administrator shall be entitled to receive an Opinion of
Counsel (provided by the Person requesting such amendment) to the effect that
such amendment is authorized or permitted by this Agreement.

                                      130
<PAGE>

                  Promptly after the execution of any such amendment the Trust
Administrator shall furnish a copy of such amendment to each Certificateholder.

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 to approve the particular form of
any proposed amendment, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable regulations as the Trust Administrator may prescribe.

                  The cost of any Opinion of Counsel to be delivered pursuant to
this Section 11.01 shall be borne by the Person seeking the related amendment,
but in no event shall such Opinion of Counsel be an expense of the Trustee or
the Trust Administrator.

                  Notwithstanding the foregoing, each of the Trustee and Trust
Administrator may, but shall not be obligated to enter into any amendment
pursuant to this Section that affects its rights, duties and immunities under
this Agreement or otherwise.

                  SECTION 11.02. Recordation of Agreement; Counterparts.

                  To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Certificateholders, but
only upon direction of Certificateholders accompanied by an Opinion of Counsel
to the effect that such recordation materially and beneficially affects the
interests of the Certificateholders.

                  For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts shall
constitute but one and the same instrument.

                  SECTION 11.03. Limitation on Rights of Certificateholders.

                  The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

                  No Certificateholder shall have any right to vote (except as
expressly provided for herein) or in any manner otherwise control the operation
and management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth, or contained in the terms of any of the
Certificates, be construed so as to constitute the Certificateholders from time
to time as partners or members of an association; nor shall any
Certificateholder be under any liability to any

                                      131

third person by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

                  No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless (i)
such Holder previously shall have given to the Trustee and the Trust
Administrator a written notice of default and of the continuance thereof, as
hereinbefore provided, and (ii) the Holders of Certificates entitled to at least
25% of the Voting Rights shall have made written request upon the Trustee and
the Trust Administrator to institute such action, suit or proceeding in its own
name as Trustee or Trust Administrator hereunder and shall have offered to the
Trustee or the Trust Administrator, as applicable, such indemnity satisfactory
to it against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee or the Trust Administrator, for 15 days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding. It is understood and
intended, and expressly covenanted by each Certificateholder with every other
Certificateholder, the Trustee and the Trust Administrator, that no one or more
Holders of Certificates shall have any right in any manner whatsoever by virtue
of any provision of this Agreement to affect, disturb or prejudice the rights of
the Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, or to enforce any right
under this Agreement, except in the manner herein provided and for the equal,
ratable and common benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section, each and every Certificateholder,
the Trustee and the Trust Administrator shall be entitled to such relief as can
be given either at law or in equity.

                  SECTION 11.04. Governing Law.

                  SECTION 11.09. Grant of Security Interest.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Depositor to the Trustee be, and be
construed as, a sale of the Mortgage Loans by the Depositor and not a pledge of
the Mortgage Loans by the Depositor to secure a debt or other obligation of the
Depositor. However, in the event that, notwithstanding the aforementioned intent
of the parties, the Mortgage Loans are held to be property of the Depositor,
then, (a) it is the express intent of the parties that such conveyance be deemed
a pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt
or other obligation of the Depositor and (b)(1) this Agreement shall also be
deemed to be a security agreement within the meaning of Articles 8 and 9 of the
Uniform Commercial Code as in effect from time to time in the State of New York;
(2) the conveyance provided for in Section 2.01 hereof shall be deemed to be a
grant by the Depositor to the Trustee of a security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and all
amounts payable to the holders of the Mortgage Loans in accordance with the
terms thereof and all proceeds of the conversion, voluntary or involuntary, of
the foregoing into cash, instruments, securities or other property, including
without limitation all amounts, other than investment earnings, from time to
time held or invested in the Collection Account and the Distribution Account,
whether in the form of cash, instruments, securities or other property; (3) the
obligations secured by such security agreement shall be deemed to be all of the
Depositor's obligations under this Agreement, including the obligation to
provide to the Certificateholders the benefits of this Agreement relating to the
Mortgage Loans and the Trust Fund; and (4) notifications to persons holding such
property, and acknowledgments, receipts or confirmations from persons holding
such property, shall be deemed notifications to, or acknowledgments, receipts or
confirmations from, financial intermediaries, bailees or agents (as applicable)
of the Trustee for the

                                      134
<PAGE>

purpose of perfecting such security interest under applicable law. Accordingly,
the Depositor hereby grants to the Trustee a security interest in the Mortgage
Loans and all other property described in clause (2) of the preceding sentence,
for the purpose of securing to the Trustee the performance by the Depositor of
the obligations described in clause (3) of the preceding sentence.
Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant
to Section 2.01 to be a true, absolute and unconditional sale of the Mortgage
Loans and assets constituting the Trust Fund by the Depositor to the Trustee.

                  IN WITNESS WHEREOF, the Depositor, the Master Servicer, the
Trust Administrator and the Trustee have caused their names to be signed hereto
by their respective officers thereunto duly authorized, in each case as of the
day and year first above written.

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

                  The Agreement permits, with certain exceptions and conditions
provided therein, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee, the Trust
Administrator and the rights of the Holders of the Certificates under the
Agreement at any time by the Depositor, the Master Servicer, the Trustee and the

                  As provided in the Agreement and subject to certain
limitations set forth therein, the transfer of this Certificate is registrable

the Agreement, duly endorsed by, or accompanied by an assignment in the form

Interest will be issued to the designated transferee or transferees.

                  The Certificates are issuable in fully registered form only

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of all the Mortgage Loans
and all property acquired in respect of such Mortgage Loans remaining therein.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan remaining therein at a price determined
as provided in the Agreement. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Loans at the time of
purchase being less than 5% of the aggregate principal balance of the Mortgage
Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

<PAGE>

an effective registration statement under the Securities Act of 1933, as amended
(the "1933 Act"), and an effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. In the event that such a transfer of
this Certificate is to be made without registration or qualification, the Trust
Administrator shall require receipt of (i) if such transfer is purportedly being
made in reliance upon Rule 144A under the 1933 Act, written certifications from
the Holder of the Certificate desiring to effect the transfer, and from such
Holder's prospective transferee, substantially in the forms attached to the
Agreement as Exhibit F-1, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Trustee, the Trust Administrator or the Master
Servicer in their respective capacities as such), together with copies of the
written certification(s) of the Holder of the Certificate desiring to effect the
transfer and/or such Holder's prospective transferee upon which such Opinion of
Counsel is based. None of the Depositor, the Trust Administrator or the Trustee
is obligated to register or qualify the Class of Certificates specified on the
face hereof under the 1933 Act or any other securities law or to take any action
not otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any Holder desiring to
effect a transfer of this Certificate shall be required to indemnify the
Trustee, the Trust Administrator, the Depositor and the Master Servicer against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of all the Mortgage Loans
and all property acquired in respect of such Mortgage Loans remaining

                                      A-4-4

therein. The Agreement permits, but does not require, the party designated in
the Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan remaining therein at a price determined
as provided in the Agreement. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Loans at the time of
purchase being less than 5% of the aggregate principal balance of the Mortgage
Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

                  The Depositor, the Master Servicer, the Trustee, the Trust
Administrator and any agent of the Depositor, the Master Servicer, the Trustee
or the Trust Administrator may treat the Person in whose name this Certificate

thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of

executed by the Trust Administrator, by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement or be valid for any purpose.

state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

                  The Depositor, the Master Servicer, the Trustee, the Trust
Administrator and any agent of the Depositor, the Master Servicer, the Trustee

designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a

effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of

executed by the Trust Administrator, by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement or be valid for any purpose.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

                                      A-8-5

<PAGE>

all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

                  The Depositor, the Master Servicer, the Trustee, the Trust
Administrator and any agent of the Depositor, the Master Servicer, the Trustee
or the Trust Administrator may treat the Person in whose name this Certificate

thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any

executed by the Trust Administrator, by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement or be valid for any purpose.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of

executed by the Trust Administrator, by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement or be valid for any purpose.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

                                     A-12-5

<PAGE>

all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

                                     A-13-5

<PAGE>

all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

provided therein, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee, the Trust
Administrator and the rights of the Holders of the Certificates under the

Interest will be issued to the designated transferee or transferees.

                  The Certificates are issuable in fully registered form only

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trust Administrator shall require receipt of
(i) if such transfer is purportedly being made in reliance upon Rule 144A under
the 1933 Act, written certifications from the Holder of the Certificate desiring
to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Trust Administrator or the Master Servicer in their respective capacities as
such), together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. None of the Depositor,
the Trust Administrator or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Trust Administrator, the
Depositor and the Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

                                     A-14-5

<PAGE>

all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of

all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans remaining therein. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from REMIC I all the Mortgage Loans and
all property acquired in respect of any Mortgage Loan remaining therein at a
price determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Loans at the
time of purchase being less than 5% of the aggregate principal balance of the
Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any

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

provided therein, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee, the Trust
Administrator and the rights of the Holders of the Certificates under the

Certificates of the same Class in authorized denominations evidencing the same

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to

                                     A-16-4

<PAGE>

an effective registration statement under the Securities Act of 1933, as amended
(the "1933 Act"), and an effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. In the event that such a transfer of
this Certificate is to be made without registration or qualification, the Trust
Administrator shall require receipt of (i) if such transfer is purportedly being
made in reliance upon Rule 144A under the 1933 Act, written certifications from
the Holder of the Certificate desiring to effect the transfer, and from such
Holder's prospective transferee, substantially in the forms attached to the
Agreement as Exhibit F-1, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Trustee, the Trust Administrator or the Master
Servicer in their respective capacities as such), together with copies of the
written certification(s) of the Holder of the Certificate desiring to effect the
transfer and/or such Holder's prospective transferee upon which such Opinion of
Counsel is based. None of the Depositor, the Trust Administrator or the Trustee
is obligated to register or qualify the Class of Certificates specified on the
face hereof under the 1933 Act or any other securities law or to take any action
not otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any Holder desiring to
effect a transfer of this Certificate shall be required to indemnify the
Trustee, the Trust Administrator, the Depositor and the Master Servicer against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any person using Plan Assets to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

                  Prior to registration of any transfer, sale or other
disposition of this Certificate, the proposed transferee shall provide to the
Trust Administrator (i) an affidavit to the effect that such transferee is any
Person other than a Disqualified Organization or the agent (including a broker,
nominee or middleman) of a Disqualified Organization, and (ii) a certificate
that acknowledges that (A) the Class R-I Certificates have been designated as a
residual interest in REMIC I, (B) it will include in its income a PRO RATA share
of the net income of the Trust Fund and that such income may be an "excess
inclusion," as defined in the Code, that, with certain exceptions, cannot be
offset by other losses or benefits from any tax exemption, and (C) it expects to
have the financial means to satisfy all of its tax obligations including those
relating to holding the Class R-I Certificates. Notwithstanding the registration
in the Certificate Register of any transfer, sale or other disposition of this
Certificate to a Disqualified Organization or an agent (including a broker,
nominee or middleman) of a Disqualified Organization, such registration shall be
deemed to be of no legal force or effect whatsoever and such Person shall not be
deemed to be a Certificateholder for any purpose, including, but not limited to,
the receipt of distributions in respect of this Certificate.

                  The Holder of this Certificate, by its acceptance hereof,
shall be deemed to have consented to the provisions of Section 5.02 of the
Agreement and to any amendment of the Agreement deemed necessary by counsel of
the Depositor to ensure that the transfer of this

                                     A-16-5

<PAGE>

Certificate to any Person other than a Permitted Transferee or any other Person
will not cause the Trust Fund to cease to qualify as a REMIC or cause the
imposition of a tax upon REMIC I.

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment (or provision for payment) to the
Holders of the Certificates of all amounts held by or on behalf of the Trust
Administrator and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment (or any advance with respect
thereto) on or other liquidation of the last Mortgage Loan remaining in REMIC I,
and (ii) the purchase by the party designated in the Agreement at a price
determined as provided in the Agreement from REMIC I of all the Mortgage Loans
and all property acquired in respect of such Mortgage Loans remaining therein.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan remaining therein at a price determined
as provided in the Agreement. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Loans at the time of
purchase being less than 5% of the aggregate principal balance of the Mortgage
Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor, and neither the Trustee nor the Trust Administrator assume any
responsibility for their correctness.

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

<PAGE>

                        MORTGAGE LOAN PURCHASE AGREEMENT

                  This is a Mortgage Loan Purchase Agreement (the "Agreement"),
dated November 25, 2003, among Citigroup Mortgage Loan Trust Inc., a Delaware
corporation (the "Purchaser"), UST Mortgage Company, a Florida corporation
("UST") and Co-Op Holdings, Inc., a Nevada corporation ("Co-Op Holdings"; and
together with UST, the "Sellers").

                              PRELIMINARY STATEMENT

                  The Sellers intend to sell the Mortgage Loans (as hereinafter
defined) on a servicing retained basis to the Purchaser on the terms and subject
to the conditions set forth in this Agreement. The Purchaser intends to deposit
the Mortgage Loans into a mortgage pool comprising the trust fund. The trust
fund will be evidenced by a single series of mortgage pass-through certificates
designated as Series 2003-UST1 (the "Certificates"). The Certificates will
consist of sixteen classes of certificates. The Certificates will be issued
pursuant to a Pooling and Servicing Agreement, dated as of November 1, 2003 (the
"Pooling and Servicing Agreement"), among the Purchaser as depositor, UST as
master servicer (the "Master Servicer"), U.S. Bank National Association as
trustee (the "Trustee") and Citibank, N.A. as trust administrator (the "Trust
Administrator"). Capitalized terms used but not defined herein shall have the
meanings set forth in the Pooling and Servicing Agreement.

                  The parties hereto agree as follows:

                  SECTION 1. AGREEMENT TO PURCHASE. The Sellers agree to sell,
and the Purchaser agrees to purchase, on or before November 26, 2003 (the
"Closing Date"), certain fixed-rate, interest-only and balloon, conventional
residential mortgage loans (the "Mortgage Loans") on a servicing retained basis,
having an aggregate principal balance as of the close of business on November 1,
2003 (the "Cut-off Date") of approximately $353,795,325.57 (the "Closing
Balance"), after giving effect to all payments due on the Mortgage Loans on or
before the Cut-off Date, whether or not received.

                  SECTION 2. MORTGAGE LOAN SCHEDULE. The Purchaser and the
Sellers have agreed upon which of the mortgage loans owned by the Sellers are to
be purchased by the Purchaser pursuant to this Agreement and the Sellers will
prepare or cause to be prepared on or prior to the Closing Date a final schedule
(the "Closing Schedule") that together shall describe such Mortgage Loans and
set forth all of the Mortgage Loans to be purchased under this Agreement. The
Closing Schedule will conform to the requirements set forth in this Agreement
and to the definition of "Mortgage Loan Schedule" under the Pooling and
Servicing Agreement. The Closing Schedule shall be used as the Mortgage Loan
Schedule under the Pooling and Servicing Agreement.

                  SECTION 3. CONSIDERATION.

                  (a) In consideration for the Mortgage Loans to be purchased
hereunder, the Purchaser shall, as described in Section 8, pay to or upon the
order of UST, on behalf of the Sellers

<PAGE>

in immediately available funds an amount (the "Purchase Price") equal to (i) the
net sale proceeds of the Class A Certificates, Class IO Certificates and the
Class PO Certificates (which amount is net of fees and expenses of Citigroup
Global Markets Inc. and Lehman Brothers Inc.), plus accrued interest and (ii)
the Class B-1 Certificates, the Class B-2 Certificates, the Class B-3
Certificates, the Class B-4 Certificates, the Class B-5 Certificates, the Class
B-6 Certificates and the Class R Certificates (the "U.S. Trust Certificates").

                  (b) The Purchaser or any assignee, transferee or designee of
the Purchaser shall be entitled to all scheduled payments of principal due after
the Cut-off Date, all other payments of principal due and collected after the
Cut-off Date, and all payments of interest on the Mortgage Loans allocable to
the period after the Cut-off Date. All scheduled payments of principal and
interest due on or before the Cut-off Date and collected after the Cut-off Date
shall belong to the Sellers.

                  (c) Pursuant to the Pooling and Servicing Agreement, the
Purchaser will assign all of its right, title and interest in and to the
Mortgage Loans, together with its rights under this Agreement, to the Trustee
for the benefit of the related Certificateholders.

                  SECTION 4. TRANSFER OF THE MORTGAGE LOANS.

               (a) POSSESSION OF MORTGAGE FILES. The Sellers do hereby sell, and
in connection therewith hereby assign to the Purchaser, effective as of the
Closing Date, without recourse but subject to the terms of this Agreement, all
of their right, title and interest in, to and under the Mortgage Loans. The
contents of each Mortgage File not delivered to the Purchaser or to any
assignee, transferee or designee of the Purchaser on or prior to the Closing
Date are and shall be held in trust by the Sellers for the benefit of the
Purchaser or any assignee, transferee or designee of the Purchaser. Upon the
sale of the Mortgage Loans, the ownership of each Mortgage Note, the related
Mortgage and the other contents of the related Mortgage File is vested in the
Purchaser and the ownership of all records and documents with respect to the
related Mortgage Loan prepared by or that come into the possession of the
Sellers on or after the Closing Date shall immediately vest in the Purchaser and
shall be delivered as soon as practicable to the Purchaser or as otherwise
directed by the Purchaser.

               (b) DELIVERY OF MORTGAGE LOAN DOCUMENTS. In connection with such
transfer and assignment, the Sellers do hereby deliver to, and deposit with, the
Purchaser or the Purchaser's designee, the documents or instruments set forth in
Section 2.01 of the Pooling and Servicing Agreement.

               In instances where an original recorded Mortgage or power of
attorney cannot be delivered by a Seller to the Purchaser prior to or
concurrently with the execution and delivery of this Agreement, due to a delay
in connection with the recording of such Mortgage, such Seller may, (a) in lieu
of delivering such original recorded Mortgage or power of attorney referred to
in clause (ii) of Section 2.01 of the Pooling and Servicing Agreement, deliver
to the Purchaser a copy thereof, provided that such Seller certifies that the
original Mortgage has been delivered to a title insurance company for
recordation after receipt of its policy of title insurance or binder therefor
(which may

<PAGE>

be a certificate relating to a master policy of title insurance), and (b) in
lieu of delivering the completed assignment in recordable form referred to in
clause (iii) of Section 2.01 of the Pooling and Servicing Agreement to the
Purchaser, deliver such assignment to the Purchaser completed except for
recording information. In all such instances, such Seller will deliver the
original recorded Mortgage and completed assignment (if applicable) to the
Purchaser promptly upon receipt of such Mortgage. In instances where an original
recorded Mortgage has been lost or misplaced, such Seller or the related title
insurance company may deliver, in lieu of such Mortgage, a copy of such Mortgage
bearing recordation information and certified as true and correct by the office
in which recordation thereof was made. In instances where the original or a copy
of the title insurance policy referred to in clause (v) of Section 2.01 of the
Pooling and Servicing Agreement (which may be a certificate relating to a master
policy of title insurance) pertaining to the Mortgaged Property relating to a
Mortgage Loan cannot be delivered by such Seller to the Purchaser prior to or
concurrently with the execution and delivery of this Agreement because such
policy is not yet available, such Seller may, in lieu of delivering the original
or a copy of such title insurance, deliver to the Purchaser a binder with
respect to such policy (which may be a certificate relating to a master policy
of title insurance) and deliver the original or a copy of such policy (which may
be a certificate relating to a master policy of title insurance) to the
Purchaser within 270 days of the Closing Date. In instances where an original
assumption, modification or buydown agreement cannot be delivered by such Seller
to the Purchaser prior to or concurrently with the execution and delivery of
this Agreement, such Seller may, in lieu of delivering the original of such
agreement, deliver a certified copy thereof.

               To the extent not already recorded, the Sellers shall promptly
(and in no event later than five Business Days following the later of the
Closing Date and the date of receipt by a Seller of the recording information
for a Mortgage) submit or cause to be submitted for recording, at no expense to
the trust fund, in the appropriate public office for real property records, each
Assignment delivered to it pursuant to Section 2.01(I)(iii) of the Pooling and
Servicing Agreement. In the event that any such Assignment is lost or returned
unrecorded because of a defect therein, the applicable Seller shall promptly
prepare or cause to be prepared a substitute Assignment or cure or cause to be
cured such defect, as the case may be, and thereafter cause each such Assignment
to be duly recorded.

               Notwithstanding the foregoing, for administrative convenience and
facilitation of servicing and to reduce closing costs, the Assignments shall not
be required to be submitted for recording (except with respect to any Mortgage
Loan located in Florida and Maryland) unless such failure to record would result
in a withdrawal or a downgrading by any Rating Agency of the rating on any Class
of Certificates; provided, however, the Sellers shall submit each Assignment for
recording, at no expense to the Trust Fund or Trustee, upon the earliest to
occur of: (i) reasonable direction by Holders of Certificates entitled to at
least 25% of the Voting Rights, (ii) the occurrence of a Master Servicer Event
of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure
relating to the applicable Seller, (iv) the occurrence of a servicing transfer
as described in Section 7.02 of the Pooling and Servicing Agreement and (v) with
respect to any one Assignment the occurrence of a foreclosure relating to the
Mortgagor under the related Mortgage.

               With respect to a maximum of approximately 1.00% of the Original
Mortgage Loans, by outstanding principal balance of the Original Mortgage Loans
as of the Cut-off Date, if any

<PAGE>

original Mortgage Note referred to in the Pooling and Servicing Agreement cannot
be located, the obligations of the Sellers to deliver such documents shall be
deemed to be satisfied upon delivery to the Purchaser of a photocopy of such
Mortgage Note, if available, with a lost note affidavit. If any of the original
Mortgage Notes for which a lost note affidavit was delivered to the Purchaser is
subsequently located, such original Mortgage Note shall be delivered to the
Trustee within three Business Days.

               The Sellers shall deliver or cause to be delivered to the
Purchaser promptly upon receipt thereof any other original documents
constituting a part of a Mortgage File received with respect to any Mortgage
Loan, including, but not limited to, any original documents evidencing an
assumption, modification, consolidation or extension of any Mortgage Loan.

               All original documents relating to the Mortgage Loans that are
not delivered to the Purchaser are and shall be held by or on behalf of the
Sellers in trust for the benefit of the Trustee on behalf of the
Certificateholders. In the event that any such original document is required
pursuant to the terms of this Section to be a part of a Mortgage File, such
document shall be delivered promptly to the Purchaser. Any such original
document delivered to or held by the Purchaser that is not required pursuant to
the terms of this Section to be a part of a Mortgage File, shall be delivered
promptly to the applicable Seller.

               (c) ACCEPTANCE OF MORTGAGE LOANS. The documents delivered
pursuant to Section 4(b) hereof shall be reviewed by the Purchaser or any
assignee, transferee or designee of the Purchaser at any time before or after
the Closing Date (and with respect to each document permitted to be delivered
after the Closing Date within seven days of its delivery) to ascertain that all
required documents have been executed and received and that such documents
relate to the Mortgage Loans identified on the Mortgage Loan Schedule.

               (d) TRANSFER OF INTEREST IN AGREEMENTS. The Purchaser has the
right to assign its interest under this Agreement, in whole or in part, to the
Trustee, as may be required to effect the purposes of the Pooling and Servicing
Agreement, without the consent of the Sellers, and the assignee shall succeed to
the rights and obligations hereunder of the Purchaser. Any expense reasonably
incurred by or on behalf of the Purchaser, the Master Servicer, the Trustee or
the Trust Administrator in connection with enforcing any obligations of either
Seller under this Agreement will be promptly reimbursed by the applicable
Seller.

               (e) EXAMINATION OF MORTGAGE FILES. Prior to the Closing Date, the
Sellers shall either (i) deliver in escrow to the Purchaser or to any assignee,
transferee or designee of the Purchaser, for examination, the Mortgage File
pertaining to each Mortgage Loan, or (ii) make such Mortgage Files available to
the Purchaser or to any assignee, transferee or designee of the Purchaser for
examination; provided, however, that the Sellers shall not be required to
provide mortgagor names or addresses to any such assignee, transferee or
designee. Such examination may be made by the Purchaser or the Trustee, and
their respective designees, upon reasonable notice to each Seller during normal
business hours before the Closing Date and within 60 days after the Closing
Date. If any such person makes such examination prior to the Closing Date and
identifies any Mortgage

<PAGE>

Loans that do not conform to the requirements of the Purchaser as described in
this Agreement, such Mortgage Loans shall be deleted from the Closing Schedule.
The Purchaser may, at its option and without notice to the Sellers, purchase all
or part of the Mortgage Loans without conducting any partial or complete
examination. The fact that the Purchaser or any person has conducted or has
failed to conduct any partial or complete examination of the Mortgage Files
shall not affect the rights of the Purchaser or any assignee, transferee or
designee of the Purchaser to demand repurchase or other relief as provided
herein or under the Pooling and Servicing Agreement.

               SECTION 5. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
                          SELLERS.

               Each Seller hereby represents and warrants, as of the date hereof
and as of the Closing Date, and covenants, that:

               (i)The Seller is a corporation, duly organized and validly
         existing and in good standing under the laws of the state of its
         incorporation with full corporate power and authority to conduct its
         business as presently conducted by it to the extent material to the
         consummation of the transactions contemplated herein. The Seller had
         the full corporate power and authority to acquire the Mortgage Loans.
         The Seller has the full corporate power and authority to own the
         Mortgage Loans and to transfer and convey the Mortgage Loans to the
         Purchaser and has the full corporate power and authority to execute and
         deliver, engage in the transactions contemplated by, and perform and
         observe the terms and conditions of this Agreement;

               (ii) This Agreement has been duly and validly authorized,
         executed and delivered by the Seller, all requisite corporate action
         having been taken, and (assuming the due authorization, execution and
         delivery hereof by the Purchaser) constitutes the valid, legal and
         binding obligation of the Seller, enforceable in accordance with its
         terms, except as such enforcement may be limited by (A) bankruptcy,
         insolvency, reorganization, receivership, moratorium or other similar
         laws relating to or affecting the rights of creditors generally, (B)
         general equity principles (regardless of whether such enforcement is
         considered in a proceeding in equity or at law) or (C) public policy
         considerations underlying the securities laws, to the extent that such
         public policy considerations limit the enforceability of the provisions
         of this Agreement which purport to provide indemnification from
         securities laws liabilities;

               (iii) No consent, approval, authorization or order of,
         registration or filing with, or notice to any governmental authority or
         court is required, under federal laws for the execution, delivery and
         performance by the Seller of, or compliance by the Seller with, this
         Agreement or the consummation by the Seller of any other transaction
         contemplated hereby and by the Pooling and Servicing Agreement;
         provided, however, that the Seller makes no representation or warranty
         regarding federal or state securities laws in connection with the sale
         or distribution of the Certificates;

               (iv) No certificate of an officer, statement or other information
         furnished in

<PAGE>

         writing or report delivered by the Seller to the Purchaser, any
         affiliate of the Purchaser or the Trustee for use in connection with
         the purchase of the Mortgage Loans and the transactions contemplated
         hereunder and under the Pooling and Servicing Agreement will contain
         any untrue statement of a material fact, or omit a material fact
         necessary to make the information, certificate, statement or report not
         misleading in any material respect;

               (v) Neither the sale of the Mortgage Loans to the Purchaser, nor
         the execution, delivery or performance of this Agreement by the Seller,
         conflicts or will conflict with or results or will result in a breach
         of or constitutes or will constitute a default (or an event, which with
         notice or lapse of time or both, would constitute a default) under (A)
         any terms or provisions of the certificate of incorporation or by-laws
         of the Seller, (B) any term or provision of any material agreement,
         contract, instrument or indenture, to which the Seller is a party or by
         which the Seller or any of its property is bound or (C) any law, rule,
         regulation, order, judgment, writ, injunction or decree of any court or
         governmental authority having jurisdiction over the Seller or any of
         its property, or results or will result in the creation or imposition
         of any lien, charge or encumbrance which would have a material adverse
         effect upon the Mortgage Loans or any documents or instruments
         evidencing or securing the Mortgage Loans;

               (vi) The Seller has not dealt with any broker, investment banker,
         agent or other person, except for the Purchaser, any of the Purchaser's
         affiliates or Lehman Brothers Inc., that may be entitled to any
         commission or compensation in connection with the sale of the Mortgage
         Loans;

               (vii) There is no litigation currently pending or, to the best of
         the Seller's knowledge, threatened against the Seller that would
         reasonably be expected to adversely affect the transfer of the Mortgage
         Loans, the issuance of the Certificates, the execution, delivery,
         performance or enforceability of this Agreement or that would result in
         a material adverse change in the financial condition of the Seller;

               (viii) To the best of the Seller's knowledge, each Mortgage Note,
         each Mortgage, each Assignment and any other document required to be
         delivered by or on behalf of the Seller under this Agreement or the
         Pooling and Servicing Agreement to the Purchaser or any assignee,
         transferee or designee of the Purchaser for each Mortgage Loan has been
         or will be, in accordance with Section 4(b) hereof, delivered to the
         Purchaser or any such assignee, transferee or designee. To the best of
         the Seller's knowledge, with respect to each Mortgage Loan, the Seller
         is in possession of a complete Mortgage File in compliance with the
         Pooling and Servicing Agreement, except for such documents that (A)
         have been delivered (1) to the Purchaser or any assignee, transferee or
         designee of the Purchaser or (2) for recording to the appropriate
         public recording office and have not yet been returned or (B) are not
         required to be delivered to the Purchaser or any assignee, transferee
         or designee of the Purchaser until 270 days following the Closing Date
         or such later date as provided in Section 4;

               (ix) The transfer, assignment and conveyance of the Mortgage
         Notes and the

<PAGE>

         Mortgages by the Seller pursuant to this Agreement are not subject to
         the bulk transfer or any similar statutory provisions in effect in any
         relevant jurisdiction, except any as may have been complied with;

               (x) The form of endorsement of each Mortgage Note satisfied the
         requirement, if any, of endorsement in order to transfer all right,
         title and interest of the party so endorsing, as noteholder or assignee
         thereof, in and to that Mortgage Note; and each Assignment to be
         delivered hereunder is, or will be, in recordable form and is, or will
         be, sufficient to effect the assignment of and to transfer to the
         assignee thereunder the benefits of the assignor, as mortgagee or
         assignee thereof, under each Mortgage to which that Assignment relates;

               (xi) Immediately prior to the sale of the Mortgage Loans to the
         Purchaser as herein contemplated, the Seller had good title to, and was
         the sole owner of, the Mortgage Loans, and such sale validly transfers
         the Mortgage Loans to the Purchaser free and clear of any pledge, lien,
         encumbrance or security interest;

               (xii) With respect to the Mortgage Loans, the Seller hereby
         represents and warrants, as of the date hereof and as of the Closing
         Date, that each Mortgage Loan constitutes a "qualified mortgage" within
         the meaning of Section 860G(a)(3) of the Code;

               (xiii) The transfer of the Mortgage Loans by the Seller was
         intended to be a sale and to be reported as such under United States
         generally accepted accounting principles ("GAAP") and for United States
         federal income tax purposes, and meets all of the requirements for such
         accounting and tax treatment (except for the GAAP requirement that the
         Mortgage Loans have been legally isolated from the Seller);

               (xiv) In connection with the sale of the Mortgage Loans by the
         Seller, the Seller (i) was solvent at all relevant times prior thereto
         and has not been rendered insolvent thereby, (ii) after giving effect
         thereto, is able to pay its debts as they mature, (iii) has not been
         left with unreasonably small capital for the business in which it is
         engaged and proposes to be engaged, (iv) had and has no intention of
         commencing any bankruptcy, insolvency or similar proceeding, (v) did
         not and does not have any intent to hinder, delay or defraud any of the
         undersigned's creditors, (vi) had a valid business reason therefor and
         (vii) received new value and consideration therefor constituting
         reasonably equivalent value and adequate and fair consideration; and

               (xv) Except with respect to its retention of the Subordinate
         Certificates, the Seller has not acquired, and does not intend to
         acquire at any time, any direct or indirect ownership or other economic
         interest in, or other right or obligation with respect to, any Mortgage
         Loan or Certificate.

               SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE SELLERS RELATING
                          TO THE MORTGAGE LOANS.

<PAGE>

               Each Seller hereby represents and warrants to the Purchaser that,
as to each Mortgage Loan, as of the Closing Date (or such other date specified
herein) for such Mortgage Loan:

               (i)The information set forth in the Mortgage Loan Schedule is
         true and correct as of the Cut-off Date;

               (ii) [Reserved];

               (iii) (a) All payments required to be made on or before the first
         day of the month prior to the month of the Closing Date, with respect
         to such Mortgage Loan under the terms of the Mortgage Note have been
         made and (b) the Seller has not advanced funds, or induced, solicited
         or knowingly received any advance of funds from a party other than the
         owner of the related Mortgaged Property, directly or indirectly, for
         the payment of any amount required by the Mortgage Note or Mortgage;

               (iv) To the best knowledge of the Seller, there are no delinquent
         taxes, ground rents, water charges, sewer rents, assessments, insurance
         premiums, leasehold payments, including assessments payable in future
         installments or other outstanding charges affecting the related
         Mortgaged Property;

               (v) To the best knowledge of the Seller, the terms of the
         Mortgage Note and (A) with respect to each Mortgage Loan, the Mortgage
         and (B) with respect to each Cooperative Loan, the Security Agreement,
         have not been impaired, waived, altered or modified in any respect,
         except by written instruments included in the Mortgage File, recorded
         in the applicable public recording office if necessary to maintain the
         lien priority of the Mortgage; the substance of any such waiver,
         alteration or modification does not affect coverage under any title
         insurance policy, and is reflected on the Mortgage Loan Schedule. To
         the best knowledge of the Seller, no instrument of waiver, alteration
         or modification has been executed by the Seller or any other person in
         the chain of title from the Seller, and no Mortgagor has been released,
         in whole or in part, except in connection with an assumption agreement
         approved by the title insurer, to the extent required by the policy,
         and the terms of which are reflected in the Mortgage Loan Schedule and
         included in the related Mortgage File;

               (vi) To the best knowledge of the Seller, prior to the transfer
         to the Purchaser by the Seller, the Mortgage Note and (A) with respect
         to each Mortgage Loan, the Mortgage and (B) with respect to each
         Cooperative Loan, the Security Agreement, are not subject to any right
         of rescission, set-off, counterclaim or defense, including the defense
         of usury, nor will the operation of any of the terms of the Mortgage
         Note and the Mortgage, or the exercise of any right thereunder, render
         the Mortgage unenforceable, in whole or in part, or subject to any
         right of rescission, set-off, counterclaim or defense, including the
         defense of usury and no such right of rescission, set-off, counterclaim
         or defense has been asserted with respect thereto;

<PAGE>

               (vii) To the best knowledge of the Seller, except with respect to
         Cooperative Loans, all buildings upon the Mortgaged Property are
         insured by a generally acceptable insurer against loss by fire, hazards
         of extended coverage and such other hazards as are customary in the
         area where the Mortgaged Property or Project is located, pursuant to
         insurance policies conforming to the requirements of the Pooling and
         Servicing Agreement. All such insurance policies contain a standard
         mortgagee clause naming the Seller or the originator of the related
         Mortgage Loan, its successors and assigns as mortgagee and all premiums
         thereon have been paid. Except with respect to Cooperative Loans, if
         upon origination of the Mortgage Loan, the Mortgaged Property or
         Project was in an area identified on a Flood Hazard Map or Flood
         Insurance Rate Map issued by the Federal Emergency Management Agency as
         having special flood hazards (and such flood insurance has been made
         available) a flood insurance policy meeting the requirements of the
         current guidelines of the Federal Insurance Administration is in effect
         which policy conforms to the requirements of Section 3.14(a) of the
         Pooling and Servicing Agreement. The Mortgage obligates the Mortgagor
         thereunder to maintain all such insurance at the Mortgagor's cost and
         expense, and on the Mortgagor's failure to do so, authorizes the holder
         of the Mortgage to maintain such insurance at the Mortgagor's cost and
         expense and to seek reimbursement therefor from the Mortgagor;

               (viii) To the best knowledge of the Seller, any and all
         requirements of any federal, state or local law including, without
         limitation, usury, truth in lending, real estate settlement procedures,
         consumer credit protection, equal credit opportunity or disclosure laws
         applicable to the origination and servicing of the Mortgage Loan have
         been complied with;

               (ix) The Mortgage has not been satisfied, canceled, subordinated
         or rescinded, in whole or in part, and the Mortgaged Property has not
         been released from the lien of the Mortgage, in whole or in part, nor
         has any instrument been executed that would effect any such
         satisfaction, cancellation, subordination, rescission or release;

               (x) The Mortgage is a valid, existing and enforceable first lien
         on the Mortgaged Property, including all improvements on the Mortgaged
         Property subject only to (a) the lien of current real property taxes
         and assessments not yet due and payable, (b) covenants, conditions and
         restrictions, rights of way, easements and other matters of the public
         record as of the date of recording being acceptable to mortgage lending
         institutions generally and specifically referred to in the lender's
         title insurance policy delivered to the originator of the Mortgage Loan
         and which do not adversely affect the appraised value of the Mortgaged
         Property, (c) if the Mortgaged Property consists of a Cooperative Unit,
         any lien for amounts due to the cooperative housing corporation for
         unpaid assessments or charges or any lien of any assignment of rents or
         maintenance expenses secured by the real property owned by the
         cooperative housing corporation and (d) other matters to which like
         properties are commonly subject which do not materially interfere with
         the benefits of the security intended to be provided by the Mortgage or
         the use, enjoyment, value or marketability of the related Mortgaged
         Property. Any security agreement, chattel mortgage or equivalent
         document related to and delivered in connection with the Mortgage Loan
         establishes and creates a

<PAGE>

         valid, existing and enforceable first lien and first priority security
         interest on the property described therein and, as of the time it
         contributed the Mortgage Loan to the Purchaser, the Seller had full
         right to contribute and assign the same to the Purchaser;

               (xi) The Mortgage Note and (A) with respect to each Mortgage
         Loan, the related Mortgage and (B) with respect to each Cooperative
         Loan, the related Security Agreement, are genuine and each is the
         legal, valid and binding obligation of the maker thereof, enforceable
         in accordance with its terms;

               (xii) To the best knowledge of the Seller, all parties to the
         Mortgage Note and the Mortgage had legal capacity to enter into the
         Mortgage Loan and to execute and deliver the Mortgage Note and the
         Mortgage, and the Mortgage Note and the Mortgage have been duly and
         properly executed by such parties. Except with respect to 13.83% of the
         Group I Mortgage Loans, 13.39% of the Group II Mortgage Loans and
         14.88% of the Group III Mortgage Loans (in each case by aggregated
         Stated Principal Balance of the related Loan Group as of the Cut-off
         Date), the Mortgagor is a natural person who is a party to the Mortgage
         Note and the Mortgage (or Security Agreement in the case of a
         Cooperative Loan) is in an individual capacity or family trust that is
         guaranteed by a natural person;

               (xiii) The proceeds of the Mortgage Loan have been fully
         disbursed to or for the account of the Mortgagor and there is no
         obligation for the Mortgagee to advance additional funds thereunder and
         any and all requirements as to completion of any on-site or off-site
         improvement and as to disbursements of any escrow funds therefor have
         been complied with. All costs, fees and expenses incurred in making or
         closing the Mortgage Loan and the recording of the Mortgage have been
         paid, and the Mortgagor is not entitled to any refund of any amounts
         paid or due to the Mortgagee pursuant to the Mortgage Note or Mortgage;

               (xiv) As of the Closing Date and prior to the sale of the
         Mortgage Loan to the Purchaser, the Seller was the sole legal,
         beneficial and equitable owner of the Mortgage Note and (A) with
         respect to each Mortgage Loan, the Mortgage and (B) with respect to
         each Cooperative Loan, the Security Agreement, and has full right to
         transfer and sell the Mortgage Loan to the Purchaser free and clear of
         any encumbrance, equity, lien, pledge, charge, claim or security
         interest;

               (xv) To the best knowledge of the Seller, all parties which have
         had any interest in (A) with respect to any Mortgage Loan, the Mortgage
         and (B) with respect to any Cooperative Loan, the Security Agreement,
         whether as mortgagee, assignee, pledgee or otherwise, are (or, during
         the period in which they held and disposed of such interest, were) in
         compliance (directly, or through an affiliate or subservicer) with any
         and all applicable "doing business" and licensing requirements of the
         laws of the state, or, if any such party was not in compliance with
         such requirements, such noncompliance will not materially and adversely
         affect the Purchaser's interest in the Mortgage Loan;

               (xvi) Except with respect to Cooperative Loans, the Mortgage Loan
         is covered by

<PAGE>

         either (i) a title insurance policy, issued by a title insurer
         qualified to do business in the jurisdiction where the Mortgaged
         Property is located, insuring (subject to the exceptions contained in
         (x)(a) and (b) above) the Seller or the originator of the related
         Mortgage Loan, its successors and assigns as to the first priority lien
         of the Mortgage in the original principal amount of the Mortgage Loan
         or (ii) an attorney's title opinion, if customary in the related
         jurisdiction where the Mortgaged Property is located. To the best of
         the Seller's knowledge, such lender's title insurance policy
         affirmatively insures ingress and egress to and from the Mortgaged
         Property, and against encroachments by or upon the Mortgaged Property
         or any interest therein. To the best of the Seller's knowledge, the
         Seller is the sole insured of such lender's title insurance policy, and
         such lender's title insurance policy is in full force and effect and
         will be in full force and effect upon the consummation of the
         transactions contemplated by this Agreement. To the best of the
         Seller's knowledge, no claims have been made under such lender's title
         insurance policy, and no prior holder of the related Mortgage,
         including the Seller, has done, by act or omission, anything which
         would impair the coverage of such lender's title insurance policy,
         except as the title insurance policy may be altered by a modification
         of the Mortgage Loan;

               (xvii) To the best of the Seller's knowledge, there is no
         default, breach, violation or event of acceleration existing under the
         Mortgage or the Mortgage Note and no event which, with the passage of
         time or with notice and the expiration of any grace or cure period,
         would constitute a default, breach, violation or event of acceleration,
         and the Seller has not waived any default, breach, violation or event
         of acceleration;

               (xviii) To the best of the Seller's knowledge, there are no
         mechanics' or similar liens or claims which have been filed for work,
         labor or material (and no rights are outstanding that under law could
         give rise to such lien) affecting the related Mortgaged Property which
         are or may be liens prior to, or equal or coordinate with, the lien of
         the related Mortgage;

               (xix) Except as noted in any related title insurance policy, all
         improvements which were considered in determining the appraised value
         of the related Mortgaged Property lay wholly within the boundaries and
         building restriction lines of the Mortgaged Property, and no
         improvements on adjoining properties encroach upon the Mortgaged
         Property;

               (xx) The Mortgage Loan was originated by the Seller or by a
         savings and loan association, a savings bank, a commercial bank or
         similar banking institution which is supervised and examined by a
         federal or state authority, or by a mortgagee approved as such by the
         Secretary of HUD;

               (xxi) Except with respect to any interest-only Mortgage Loan or
         any construction to permanent Mortgage Loan, principal payments on the
         Mortgage Loan commenced no more than two months after the proceeds of
         the Mortgage Loan were disbursed. The Mortgage Loan bears interest at
         the Mortgage Rate. The Mortgage Note is payable on the day of each
         month set forth in the Mortgage Loan Schedule and in Monthly Payments
         which will amortize the Stated Principal Balance of the Mortgage Loan
         over its remaining term at the

<PAGE>

         Mortgage Rate. Interest on the Mortgage Loan is calculated on the basis
         of a 360-day year consisting of twelve 30-day months;

               (xxii) The origination and collection practices used by the
         Seller with respect to each Mortgage Note and Mortgage have been in all
         respects legal, proper, prudent and customary in the mortgage
         origination and servicing industry. The Mortgage Loan has been serviced
         by the Master Servicer (directly or through a subservicer) and any
         predecessor servicer in accordance with the terms of the Mortgage Note;

               (xxiii) To the best knowledge of the Seller, (A) with respect to
         each Mortgage Loan, the Mortgaged Property and (B) with respect to each
         Cooperative Loan, the related Cooperative Unit, is free of damage and
         waste and there is no proceeding pending for the total or partial
         condemnation thereof;

               (xxiv) The Mortgage and related Mortgage Note contain customary
         and enforceable provisions such as to render the rights and remedies of
         the holder thereof adequate for the realization against the Mortgaged
         Property of the benefits of the security provided thereby, including,
         (a) in the case of a Mortgage designated as a deed of trust, by
         trustee's sale and (b) otherwise by judicial foreclosure. To the best
         of the Seller's knowledge, there is no homestead or other exemption
         available to the Mortgagor which would interfere with the right to sell
         the Mortgaged Property at a trustee's sale or the right to foreclose
         the Mortgage. The Mortgagor has not notified the Seller and the Seller
         has no knowledge of any relief requested or allowed to the Mortgagor
         under the Soldiers and Sailors Civil Relief Act of 1940;

               (xxv) The Mortgage Note is not secured by any collateral (other
         than a personal guarantee, if applicable) except the lien of the
         corresponding Mortgage on the Mortgaged Property and the security
         interest of any applicable security agreement or chattel mortgage
         referred to in (x) above;

               (xxvi) The Mortgage File contains an appraisal of the related
         Mortgaged Property made and signed, prior to the approval of the
         Mortgage Loan application, by a qualified appraiser, approved by the
         Seller, who had no interest, direct or indirect in the Mortgaged
         Property or in any loan made on the security thereof, whose
         compensation is not affected by the approval or disapproval of the
         Mortgage Loan and who would meet the minimum qualifications of Fannie
         Mae and Freddie Mac or who met the minimum qualifications approved by
         the institution that originated the related Mortgage Loan;

               (xxvii) To the best of the Seller's knowledge, in the event the
         Mortgage constitutes a deed of trust, a trustee, duly qualified under
         applicable law to serve as such, has been properly designated and
         currently so serves and is named in the Mortgage, and no fees or
         expenses are or will become payable by the Purchaser to the trustee
         under the deed of trust, except in connection with a trustee's sale
         after default by the Mortgagor;

<PAGE>

               (xxviii) To the best of the Seller's knowledge, no Mortgage Loan
         contains provisions pursuant to which Monthly Payments are (a) paid or
         partially paid with funds deposited in any separate account established
         by the Seller, the Mortgagor, or anyone on behalf of the Mortgagor, (b)
         paid by any source other than the Mortgagor or (c) contains any other
         similar provisions which may constitute a "buydown" provision. The
         Mortgage Loans are not graduated payment mortgage loans and the
         Mortgage Loans do not have shared appreciation or other contingent
         interest features;

               (xxix) To the best of the Seller's knowledge, if the Mortgage
         Loan is a Refinanced Mortgage Loan, the Mortgagor has received all
         disclosure and rescission materials required by applicable law with
         respect to the making of a Refinanced Mortgage Loan, and evidence of
         such receipt is and will remain in the Mortgage File;

               (xxx) With respect to each Mortgage Loan, either (i) it was not
         made in connection with the construction or rehabilitation of a
         Mortgaged Property or (ii) as of the Cut-off Date, the construction
         phase of such Mortgage Loan has expired;

               (xxxi) All documents required to be delivered with respect to
         each Mortgage Loan or Cooperative Loan pursuant to the Pooling and
         Servicing Agreement, have been or will be delivered to the Trustee in
         compliance with the specific requirements of the Pooling and Servicing
         Agreement;

               (xxxii) To the best knowledge of the Seller, (A) with respect to
         each Mortgage Loan, the Mortgaged Property and (B) with respect to each
         Cooperative Loan, the Cooperative Unit, is lawfully occupied under
         applicable law; all inspections, licenses and certificates required to
         be made or issued with respect to all occupied portions of the
         Mortgaged Property and, with respect to the use and occupancy of the
         same, including but not limited to certificates of occupancy, have been
         made or obtained from the appropriate authorities;

               (xxxiii) The Assignment is or will be in recordable form and is
         or will be acceptable for recording under the laws of the jurisdiction
         in which the Mortgaged Property is located;

               (xxxiv) Any principal advances made to the Mortgagor prior to the
         Cut-off Date have been consolidated with the outstanding principal
         amount secured by the Mortgage, and the secured principal amount, as
         consolidated, bears a single interest rate and single repayment term.
         The lien of the Mortgage securing the consolidated principal amount is
         expressly insured as having first lien priority by a title insurance
         policy or an endorsement to the policy insuring the mortgagee's
         consolidated interest. The consolidated principal amount does not
         exceed the original principal amount of the Mortgage Loan;

               (xxxv) The Mortgage Loan was not intentionally selected by the
         Seller in a manner intended to adversely affect the interest of the
         Purchaser;

               (xxxvi) [Reserved];

<PAGE>

               (xxxvii) Except with respect to any Cooperative Loan, the
         Mortgaged Property consists of (i) a parcel of real property with a
         single family residence erected thereon, or (ii) a two to four-family
         dwelling, or (iii) an individual condominium unit in a low-rise or
         high-rise condominium project, or (iv) an individual unit in a planned
         unit development. Except with respect to any Cooperative Loan, the
         Mortgaged Property is improved with a Residential Dwelling. To the best
         knowledge of the Seller, the Mortgaged Property does not consist of
         mobile homes or manufactured homes (as defined in the Fannie Mae
         Originator-Servicer's Guide), except when the appraisal indicates that
         the home is of comparable construction to a stick or beam construction
         home, is readily marketable, has been permanently affixed to the site
         and is not in a mobile home "park." Except with respect to any
         Cooperative Loan, each Mortgaged Property is a fee simple estate;

               (xxxviii) As of the Closing Date, the Loan-to-Value Ratio of any
         Mortgage Loan was not greater than 95.00%;

               (xxxix) The Mortgage, and if required by applicable law the
         related Mortgage Note, contains a provision for the acceleration of the
         payment of the unpaid principal balance of the Mortgage Loan in the
         event that the Mortgaged Property is sold or transferred without the
         prior written consent of the Mortgagee, at the option of the Mortgagee;

               (xl) To the best knowledge of the Seller, no error, omission,
         misrepresentation, negligence, fraud or similar occurrence with respect
         to a Mortgage Loan has taken place on the part of any person,
         including, without limitation, the Mortgagor, any appraiser, any
         builder or developer, or any other party involved in the origination of
         the Mortgage Loan or in the application of any insurance in relation to
         such Mortgage Loan;

               (xli) To the best knowledge of the Seller, with respect to any
         assumption, modification, consolidation or extension agreements, such
         agreement has been recorded by the Seller if required under applicable
         law;

               (xlii) With respect to each Cooperative Loan, a cooperative lien
         search has been made by a company competent to make the same and
         qualified to do business in the jurisdiction where the Cooperative Unit
         is located;

               (xliii) With respect to each Cooperative Loan, (i) the terms of
         the related proprietary lease is longer than the terms of the
         Cooperative Loan, (ii) there is no provision in any proprietary lease
         which requires the Mortgagor to offer for sale the Cooperative Assets
         owned by such Mortgagor first to the Cooperative, (iii) there is no
         prohibition in any proprietary lease against pledging the Cooperative
         Assets or assigning the proprietary lease and (iv) the recognition
         agreement is on a form of agreement published by the Aztech Document
         Systems, Inc. or includes provisions which are no less favorable to the
         lender than those contained in such agreement;

               (xliv) With respect to each Cooperative Loan, each original UCC
         financing

<PAGE>

         statement, continuation statement or other governmental filing or
         recordation necessary to create or preserve the perfection and priority
         of the first priority lien and security interest in the Cooperative
         Assets and proprietary lease has been timely and properly made. Any
         security agreement, chattel mortgage or equivalent document related to
         the Cooperative Loan and delivered to the Mortgagor or its designee
         establishes in the Mortgagor a valid and subsisting perfected first
         lien on and security interest in the Mortgaged Property described
         therein, and the Mortgagor has full right to sell and assign the same;

               (xlv) With respect to each Cooperative Loan, each acceptance of
         assignment and assumption of lease agreement contains enforceable
         provisions such as to render the rights and remedies of the holder
         thereof adequate for the realization of the benefits of the security
         provided thereby. The acceptance of assignment and assumption of lease
         agreement contains an enforceable provision for the acceleration of the
         payment of the unpaid principal balance of the Mortgage Note in the
         event the Cooperative Unit is transferred or sold without the consent
         of the holder thereof;

               (xlvi) Each Mortgage Loan at origination complied in all material
         respects with applicable local, state and federal laws, including,
         without limitation, usury, equal credit opportunity, predatory and
         abusive lending laws, real estate settlement procedures, truth-in-
         lending and disclosure laws, and consummation of the transactions
         contemplated hereby will not involve the violation of any such laws;

               (xlvii) No Mortgage Loan is a "high cost", a "covered" or any
         other similarly designated loan as defined by applicable local, state
         and federal law which contains provisions that may result in liability
         to the purchaser or assignee of the loan; and

               (xlviii) None of the Mortgage Loans are covered by the Home
         Ownership and Equity Protection Act of 1994 ("HOEPA").

               SECTION 7. REPURCHASE OBLIGATION FOR DEFECTIVE DOCUMENTATION AND
                          FOR BREACH OF REPRESENTATION AND WARRANTY.

               (a) The representations and warranties contained in Section 6
shall not be impaired by any review and examination of loan files or other
documents evidencing or relating to the Mortgage Loans or any failure on the
part of the Seller or the Purchaser to review or examine such documents and
shall inure to the benefit of any assignee, transferee or designee of the
Purchaser, including the Trustee for the benefit of holders of the Certificates
evidencing an interest in all or a portion of the Mortgage Loans. With respect
to the representations and warranties contained herein which are made to the
knowledge or the best of knowledge of the Seller, or as to which the Seller has
no knowledge, if it is discovered that the substance of any such representation
and warranty was inaccurate as of the date such representation and warranty was
made or deemed to be made, and such inaccuracy materially and adversely affects
the value of the related Mortgage Loan or the interest therein of the Purchaser
or the Purchaser's assignee, transferee or designee, then notwithstanding the
lack of knowledge by the Seller with respect to the substance of such

<PAGE>

representation and warranty being inaccurate at the time the representation and
warranty was made, the Seller shall take such action described in the following
paragraph in respect of such Mortgage Loan.

               Upon discovery by the Sellers, the Purchaser or any assignee,
transferee or designee of the Purchaser of any materially defective document in,
or that any material document was not transferred by the Sellers as part of any
Mortgage File or of a breach of any of the representations and warranties
contained in Section 5 or Section 6 that materially and adversely affects the
value of any Mortgage Loan, the Purchaser or the Purchaser's assignee,
transferee or designee or the party discovering the breach shall give prompt
written notice to the Sellers. Within ninety (90) days of its discovery or its
receipt of notice of any such missing documentation which was not transferred to
the Purchaser as described above or materially defective documentation or any
breach of a representation and warranty, the Sellers promptly shall deliver such
missing document or cure such defect or breach in all material respects, or in
the event the Sellers cannot deliver such missing document or such defect or
breach cannot be cured, the Sellers shall within ninety (90) days of its
discovery or receipt of notice, either (i) repurchase the affected Mortgage Loan
at the Purchase Price or (ii) pursuant to the provisions of the Pooling and
Servicing Agreement, cause the removal of such Mortgage Loan from the Trust Fund
and substitute one or more Qualified Substitute Mortgage Loans. With respect to
Mortgage Loans where the Mortgage File is missing a material document that was
transferred from the Sellers to the Purchaser, the Purchaser or the Purchaser's
assignee, transferee or designee, the party discovering such breach shall give
prompt written notice to the Sellers. The Sellers shall amend the Closing
Schedule to reflect the withdrawal of such Mortgage Loan from the terms of this
Agreement and the Pooling and Servicing Agreement and the addition, if any, of a
Qualified Substitute Mortgage Loan. The Sellers shall deliver to the Purchaser
such amended Closing Schedule and shall deliver such other documents as are
required by this Agreement or the Pooling and Servicing Agreement within five
(5) days of any such amendment. Any repurchase pursuant to this Section 7(a)
shall be accomplished by remittance to the Master Servicer for deposit in the
Collection Account of the amount of the Purchase Price (as defined in the
Pooling and Servicing Agreement) in accordance with Section 2.03 of the Pooling
and Servicing Agreement. Any repurchase or substitution required by this Section
shall be made in a manner consistent with Section 2.03 of the Pooling and
Servicing Agreement.

               (b) It is understood and agreed that the obligations of the
Sellers set forth in this Section 7 to cure, repurchase or substitute for a
defective Mortgage Loan constitute the sole remedies of the Purchaser against
the Sellers, respecting a missing or defective document or a breach of the
representations and warranties contained in Section 5 or Section 6. It is
understood and agreed that the obligations of the Sellers set forth in this
Section 7 to repurchase or substitute for a Mortgage Loan as to which a material
document is missing constitute the sole remedies of the Purchaser against the
Seller respecting a missing document.

               SECTION 8. CLOSING; PAYMENT FOR THE MORTGAGE LOANS. The closing
of the purchase and sale of the Mortgage Loans shall be held at the New York
City office of Thacher Proffitt & Wood at 10:00 AM New York City time on the
Closing Date.

<PAGE>

               The closing shall be subject to each of the following conditions:

               (a) All of the representations and warranties of the Sellers
         under this Agreement shall be true and correct in all material respects
         as of the date as of which they are made and no event shall have
         occurred which, with notice or the passage of time, would constitute a
         default under this Agreement;

               (b) The Purchaser shall have received, or the attorneys of the
         Purchaser shall have received in escrow (to be released from escrow at
         the time of closing), all Closing Documents as specified in Section 9
         of this Agreement, in such forms as are agreed upon and acceptable to
         the Purchaser, duly executed by all signatories other than the
         Purchaser as required pursuant to the respective terms thereof;

               (c) The Sellers shall have delivered or caused to be delivered
         and released to the Purchaser or to its designee, all documents
         (including without limitation, the Mortgage Loans) required to be so
         delivered by the Purchaser; and

               (d) All other terms and conditions of this Agreement shall have
         been complied with in all material respects.

               Subject to the foregoing conditions, the Purchaser shall deliver
or cause to be delivered to the Sellers on the Closing Date, against delivery
and release by the Sellers to the Trustee of all documents required pursuant to
the Pooling and Servicing Agreement, the consideration for the Mortgage Loans as
specified in Section 3 of this Agreement, by delivery to UST, on behalf of the
Sellers, of the Purchase Price.

               (a) An Officers' Certificate of each Seller, dated the Closing
         Date, upon which the Purchaser and Citigroup Global Markets Inc. and
         Lehman Brothers Inc. (the "Underwriters") may rely, in a form

         certificate of incorporation, by-laws and certificate of good standing
         of each Seller;

               (b) [Reserved];

               (c) An Opinion of Counsel of each Seller, dated the Closing Date
         and addressed to the Purchaser and the Underwriters, in a form
         acceptable to the Purchaser;

               (d) Such opinions of counsel as the Rating Agencies or the
         Trustee may request in connection with the sale of the Mortgage Loans
         by the Sellers to the Purchaser or the Seller's execution and delivery
         of, or performance under, this Agreement;

               (e) A letter from Deloitte & Touche, LLP, certified public
         accountants, dated the

<PAGE>

         date hereof and to the effect that they have performed certain
         specified procedures as a result of which they determined that certain
         information of an accounting, financial or statistical nature set forth
         in the Purchaser's Prospectus Supplement, dated November 25, 2003 under
         the subheadings "Summary of Prospectus Supplement--The Mortgage Loans,"
         "Risk Factors" (to the extent of information regarding the Mortgage
         Loans therein) and "The Mortgage Pool" agrees with the records of the
         Sellers;

               (f)A letter from Deloitte & Touche, LLP, certified public
         accountants, dated the date hereof and to the effect that they have
         performed certain specified procedures as a result of which they
         determined that certain information of an accounting, financial or
         statistical nature set forth in the Purchaser's Prospectus Supplement,
         dated November 25, 2003 under the subheading "Pooling and Servicing
         Agreement--The Master Servicer" agrees with the records of the Master
         Servicer; and

               (g) Such further information, certificates, opinions and
         documents as the Purchaser or the Underwriter may reasonably request.

               SECTION 10. COSTS. The Sellers shall pay (or shall reimburse the
Purchaser or any other Person to the extent that the Purchaser or such other
Person shall pay) all necessary and reasonable costs and expenses incurred
directly in connection with the transfer and delivery of the Mortgage Loans,
including without limitation, recording fees, fees for title policy endorsements

Supplement, and private placement memorandum relating to the Certificates and
other related documents, the initial fees, costs and expenses of the Trustee set
forth in an engagement letter delivered to UST by the Trustee, the fees and

documents relating to the securitization of the Mortgage Loans, the filing fee
charged by the Securities and Exchange Commission for registration of the
Certificates, the fees charged by any rating agency to rate the Certificates and

party incurring such expense.

               SECTION 11. [Reserved].

               SECTION 12. MANDATORY DELIVERY; GRANT OF SECURITY INTEREST. The
sale and delivery on the Closing Date of the Mortgage Loans described on the
Mortgage Loan Schedule in accordance with the terms and conditions of this
Agreement is mandatory. It is specifically understood and agreed that each
Mortgage Loan is unique and identifiable on the date hereof and that an award of
money damages would be insufficient to compensate the Purchaser for the losses
and damages incurred by the Purchaser in the event of the Sellers' failure to
deliver the Mortgage Loans on or before the Closing Date. The Sellers hereby
grants to the Purchaser a lien on and a continuing security interest in each
Seller's interest in each Mortgage Loan and each document and instrument
evidencing each such Mortgage Loan to secure the performance by each Seller of
its obligation hereunder, and each Seller agrees that it holds such Mortgage
Loans in custody for the Purchaser,

<PAGE>

subject to the Purchaser's (i) right, prior to the Closing Date, to reject any
Mortgage Loan to the extent permitted by this Agreement and (ii) obligation to
deliver or cause to be delivered the consideration for the Mortgage Loans
pursuant to Section 8 hereof. Any Mortgage Loans rejected by the Purchaser shall
concurrently therewith be released from the security interest created hereby.
Each Seller agrees that, upon acceptance of the Mortgage Loans by the Purchaser
or its designee and delivery of payment to UST, on behalf the Sellers, that its
security interest in the Mortgage Loans shall be released. All rights and
remedies of the Purchaser under this Agreement are distinct from, and cumulative
with, any other rights or remedies under this Agreement or afforded by law or
equity and all such rights and remedies may be exercised concurrently,
independently or successively.

               Notwithstanding the foregoing, if on the Closing Date, either (i)
each of the conditions set forth in Section 8 hereof shall have been satisfied
and the Purchaser shall not have paid or caused to be paid the Purchase Price,
or (ii) any such condition shall not have been waived or satisfied and the
Purchaser determines not to pay or cause to be paid the Purchase Price, the
Purchaser shall immediately effect the redelivery of the Mortgage Loans, if
delivery to the Purchaser has occurred and the security interest created by this
Section 12 shall be deemed to have been released; provided, however, in the case
of any such nonpayment described in clause (i) above, such redelivery shall not
diminish any other rights or remedies that the Seller may have against the
Purchaser.

               SECTION 13. NOTICES. All demands, notices and communications
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered to or mailed by registered mail, postage prepaid, or
transmitted by telex or telegraph and confirmed by a similar mailed writing, if
to the Purchaser, addressed to the Purchaser at 390 Greenwich Street, New York,
New York 10013, Attention: Mortgage Finance Group, or such other address as may
hereafter be furnished to the Seller in writing by the Purchaser; if to the
Sellers, addressed to them at 190 Congress Park Drive, Suite 100, Delray Beach,
Florida 33445, Attention: Loan Sale Servicing Section, or to such other address
as the Sellers may designate in writing to the Purchaser.

               SECTION 14. SEVERABILITY OF PROVISIONS. Any part, provision,
representation or warranty of this Agreement which is prohibited or which is
held to be void or unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
hereof. Any part, provision, representation or warranty of this Agreement which
is prohibited or unenforceable or is held to be void or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective, to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction as to any Mortgage Loan shall not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, the parties hereto waive any provision of law which prohibits
or renders void or unenforceable any provision hereof.

               SECTION 15. AGREEMENT OF PARTIES. The Sellers and the Purchaser
each agree to execute and deliver such instruments and take such actions as
either of the others may, from time to time, reasonably request in order to

<PAGE>

               SECTION 16. SURVIVAL. The Sellers agree that the representations,
warranties and agreements made by each Seller herein and in any certificate or
other instrument delivered pursuant hereto shall be deemed to be relied upon by
the Purchaser, notwithstanding any investigation heretofore or hereafter made by
the Purchaser or on its behalf, and that the representations, warranties and
agreements made by the Seller herein or in any such certificate or other
instrument shall survive the delivery of and payment for the Mortgage Loans and
shall continue in full force and effect, notwithstanding any restrictive or
qualified endorsement on the Mortgage Notes and notwithstanding subsequent
termination of this Agreement, the Pooling and Servicing Agreement or the Trust
Fund.

               SECTION 17. RESERVED.

               SECTION 18. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS, DUTIES,
OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES HERETO SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS (INCLUDING THE CHOICE OF LAW PROVISIONS)
AND DECISIONS OF THE STATE OF NEW YORK. THE PARTIES HERETO INTEND THAT THE
PROVISIONS OF SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW SHALL APPLY
TO THIS AGREEMENT.

               SECTION 19. MISCELLANEOUS. This Agreement may be executed in two
or more counterparts, each of which when so executed and delivered shall be an
original, but all of which together shall constitute one and the same
instrument. This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective successors and assigns. This Agreement
supersedes all prior agreements and understandings relating to the subject
matter hereof. Neither this Agreement nor any term hereof may be changed,
waived, discharged or terminated orally, but only by an instrument in writing
signed by the party against whom enforcement of the change, waiver, discharge or
termination is sought. The headings in this Agreement are for purposes of
reference only and shall not limit or otherwise affect the meaning hereof.

               It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Sellers to the Purchaser as provided in
Section 4 hereof be, and be construed as, a sale of the Mortgage Loans by the
Sellers to the Purchaser and not as a pledge of the Mortgage Loans by the
Sellers to the Purchaser to secure a debt or other obligation of the Sellers.
However, in the event that, notwithstanding the aforementioned intent of the
parties, the Mortgage Loans are held to be property of the Sellers, then, (a) it
is the express intent of the parties that such conveyance be deemed a pledge of
the Mortgage Loans by the Sellers to the Purchaser to secure a debt or other
obligation of the Sellers and (b) (1) this Agreement shall also be deemed to be
a security agreement within the meaning of Articles 8 and 9 of the New York
Uniform Commercial Code; (2) the conveyance provided for in Section 4 hereof
shall be deemed to be a grant by the Sellers to the Purchaser of a security
interest in all of each Seller's right, title and interest in and to the
Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in
accordance with the terms thereof and all proceeds of the conversion, voluntary
or involuntary, of the foregoing into cash, instruments, securities or other
property, including without limitation all amounts, other than investment
earnings, from time to time held or invested in the Collection Account whether
in the form of cash,

<PAGE>

instruments, securities or other property; (3) the possession by the Purchaser
or its agent of Mortgage Notes, the related Mortgages and such other items of
property that constitute instruments, money, negotiable documents or chattel
paper shall be deemed to be "possession by the secured party" for purposes of
perfecting the security interest pursuant to Section 9-305 of the New York
Uniform Commercial Code; and (4) notifications to persons holding such property,
and acknowledgments, receipts or confirmations from persons holding such
property, shall be deemed notifications to, or acknowledgments, receipts or
confirmations from, financial intermediaries, bailees or agents (as applicable)
of the Purchaser for the purpose of perfecting such security interest under
applicable law. Any assignment of the interest of the Purchaser pursuant to
Section 4(d) hereof shall also be deemed to be an assignment of any security
interest created hereby. The Sellers and the Purchaser shall, to the extent
consistent with this Agreement, take such actions as may be necessary to ensure
that, if this Agreement were deemed to create a security interest in the
Mortgage Loans, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of this Agreement and the Pooling and Servicing
Agreement.

               IN WITNESS WHEREOF, the Purchaser and the Sellers have caused
their names to be signed by their respective officers thereunto duly authorized
as of the date first above written.

                  3. The term "SECURITIES" as used herein DOES NOT INCLUDE (i)
securities of issuers that are affiliated with the Transferee, (ii) securities
that are part of an unsold allotment to or subscription by the Transferee, if
the Transferee is a dealer, (iii) securities issued or guaranteed by the U.S. or
any instrumentality thereof, (iv) bank deposit notes and certificates of
deposit, (v) loan participations, (vi) repurchase agreements, (vii) securities
owned but subject to a repurchase agreement and (viii) currency, interest rate
and commodity swaps.

                  4. For purposes of determining the aggregate amount of
securities owned and/or invested on a discretionary basis by the Transferee, the
Transferee used the cost of such securities to the Transferee and did not
include any of the securities referred to in the preceding paragraph. Further,
in determining such aggregate amount, the Transferee may have included
securities owned by subsidiaries of the Transferee, but only if such
subsidiaries are consolidated with the Transferee in its financial statements
prepared in accordance with generally accepted accounting principles and if the
investments of such subsidiaries are managed under the Transferee's direction.
However, such securities were not included if the Transferee is a
majority-owned, consolidated subsidiary of another enterprise and the Transferee
is not itself a reporting company under the Securities Exchange Act of 1934.

                  5. The Transferee acknowledges that it is familiar with Rule
144A and understands that the Transferor and other parties related to the
Certificates are relying and will continue to rely on the statements made herein
because one or more sales to the Transferee may be in reliance on Rule 144A.

         ___      ___      Will the Transferee be purchasing the Certificates
         Yes      No  only for the Transferee's own account?

                                      F-1-6

<PAGE>

                  6. If the answer to the foregoing question is "no", the
Transferee agrees that, in connection with any purchase of securities sold to
the Transferee for the account of a third party (including any separate account)
in reliance on Rule 144A, the Transferee will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third party unless the Transferee has
obtained a current representation letter from such third party or taken other
appropriate steps contemplated by Rule 144A to conclude that such third party
independently meets the definition of "qualified institutional buyer" set forth
in Rule 144A.

                  7. The Transferee will notify each of the parties to which
this certification is made of any changes in the information and conclusions
herein. Until such notice is given, the Transferee's purchase of the
Certificates will constitute a reaffirmation of this certification as of the
date of such purchase. In addition, if the Transferee is a bank or savings and
loan as provided above, the Transferee agrees that it will furnish to such
parties updated annual financial statements promptly after they become
available.

            --------------------------------------------------------

           [For Transferees That Are Registered Investment Companies]

                  The undersigned hereby certifies as follows to [name of
Transferor] (the "Transferor") and Citibank, N.A., as Trust Administrator, with
respect to the mortgage pass- through certificates (the "Certificates")
described in the Transferee Certificate to which this certification relates and
to which this certification is an Annex:

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

                  2. In connection with purchases by the Transferee, the
Transferee is a "qualified institutional buyer" as defined in Rule 144A because
(i) the Transferee is an investment company registered under the Investment
Company Act of 1940, and (ii) as marked below, the Transferee alone, or the
Transferee's Family of Investment Companies, owned at least $100,000,000 in
securities (other than the excluded securities referred to below) as of the end
of the Transferee's most recent fiscal year. For purposes of determining the
amount of securities owned by the Transferee or the Transferee's Family of
Investment Companies, the cost of such securities was used.

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

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

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

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

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

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

                  6. The undersigned will notify the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice, the Transferee's purchase of the Certificates will constitute
a reaffirmation of this certification by the undersigned as of the date of such
purchase.

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF NEW YORK                   )

COUNTY OF NEW YORK                  )

                  __________________________, being duly sworn, deposes,
represents and warrants as follows:

                  1. I am a ______________________ of
____________________________ (the "Owner") a corporation duly organized and
existing under the laws of ______________, the record owner of Citigroup
Mortgage Loan Trust, Series 2003-UST1, Mortgage Pass-Through Certificates, Class
R Certificates, (the "Class R Certificates"), on behalf of whom I make this
affidavit and agreement. Capitalized terms used but not defined herein have the
respective meanings assigned thereto in the Pooling and Servicing Agreement
pursuant to which the Class R Certificates were issued.

                  2. The Owner (i) is and will be a "Permitted Transferee" as of
____________, 20__ and (ii) is acquiring the Class R Certificates for its own
account or for the account of another Owner from which it has received an
affidavit in substantially the same form as this affidavit. A "Permitted
Transferee" is any person other than a "disqualified organization" or a
possession of the United States. For this purpose, a "disqualified organization"
means the United States, any state or political subdivision thereof, any agency
or instrumentality of any of the foregoing (other than an instrumentality all of
the activities of which are subject to tax and, except for the Federal Home Loan
Mortgage Corporation, a majority of whose board of directors is not selected by
any such governmental entity) or any foreign government, international
organization or any agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any organization
(other than certain farmers' cooperatives) that is generally exempt from federal
income tax unless such organization is subject to the tax on unrelated business
taxable income.

                  3. The Owner is aware (i) of the tax that would be imposed on
transfers of the Class R Certificates to disqualified organizations under the
Internal Revenue Code of 1986 that applies to all transfers of the Class R
Certificates after March 31, 1988; (ii) that such tax would be on the transferor
or, if such transfer is through an agent (which person includes a broker,
nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that
the person otherwise liable for the tax shall be relieved of liability for the
tax if the transferee furnishes to such person an affidavit that the transferee
is a Permitted Transferee and, at the time of transfer, such person does not
have actual knowledge that the affidavit is false; and (iv) that each of the
Class R Certificates may be a "noneconomic residual interest" within the meaning
of proposed Treasury regulations promulgated under the Code and that the
transferor of a "noneconomic residual interest" will remain liable for any

                                      F-2-1

<PAGE>

taxes due with respect to the income on such residual interest, unless no
significant purpose of the transfer is to impede the assessment or collection of
tax.

                  4. The Owner is aware of the tax imposed on a "pass-through
entity" holding the Class R Certificates if, at any time during the taxable year
of the pass-through entity, a non-Permitted Transferee is the record holder of
an interest in such entity. (For this purpose, a "pass-through entity" includes
a regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

                  5. The Owner is aware that the Trustee will not register the
transfer of any Class R Certificate unless the transferee, or the transferee's
agent, delivers to the Trustee, among other things, an affidavit in
substantially the same form as this affidavit. The Owner expressly agrees that
it will not consummate any such transfer if it knows or believes that any of the
representations contained in such affidavit and agreement are false.

                  6. The Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificates will only be
owned, directly or indirectly, by an Owner that is a Permitted Transferee.

                  7. The Owner's taxpayer identification number is
_________________.

                  8. The Owner has reviewed the restrictions set forth on the
face of the Class R Certificates and the provisions of Section 5.02(d) of the
Pooling and Servicing Agreement under which the Class R Certificates were issued
(in particular, clauses (iii)(A) and (iii)(B) of Section 5.02(d) which authorize
the Trustee to deliver payments to a person other than the Owner and negotiate a
mandatory sale by the Trustee in the event that the Owner holds such Certificate
in violation of Section 5.02(d)); and that the Owner expressly agrees to be
bound by and to comply with such restrictions and provisions.

                  9. The Owner is not acquiring and will not transfer the Class
R Certificates in order to impede the assessment or collection of any tax.

                  10. The Owner anticipates that it will, so long as it holds
the Class R Certificates, have sufficient assets to pay any taxes owed by the
holder of such Class R Certificates, and hereby represents to and for the
benefit of the person from whom it acquired the Class R Certificates that the
Owner intends to pay taxes associated with holding such Class R Certificates as
they become due, fully understanding that it may incur tax liabilities in excess
of any cash flows generated by the Class R Certificates.

                  11. The Owner has no present knowledge that it may become
insolvent or subject to a bankruptcy proceeding for so long as it holds the
Class R Certificates.

                                      F-2-2

<PAGE>

                  12. The Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding.

                  13. The Owner is not acquiring the Class R Certificates with
the intent to transfer the Class R Certificates to any person or entity that
will not have sufficient assets to pay any taxes owed by the holder of such
Class R Certificates, or that may become insolvent or subject to a bankruptcy
proceeding, for so long as the Class R Certificates remain outstanding.

                  14. The Owner will, in connection with any transfer that it
makes of the Class R Certificates, obtain from its transferee the
representations required by Section 5.02(d) of the Pooling and Servicing
Agreement under which the Class R Certificate were issued and will not
consummate any such transfer if it knows, or knows facts that should lead it to
believe, that any such representations are false.

                  15. The Owner will, in connection with any transfer that it
makes of the Class R Certificates, deliver to the Trustee an affidavit, which
represents and warrants that it is not transferring the Class R Certificates to
impede the assessment or collection of any tax and that it has no actual
knowledge that the proposed transferee: (i) has insufficient assets to pay any
taxes owed by such transferee as holder of the Class R Certificates; (ii) may
become insolvent or subject to a bankruptcy proceeding for so long as the Class
R Certificates remains outstanding; and (iii) is not a "Permitted Transferee".

                  16. The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, or an estate or
trust whose income from sources without the United States may be included in
gross income for United States federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States.

                  __________________________, being duly sworn, deposes,
represents and warrants as follows:

                  1. I am a ____________________ of ____________________________
(the "Owner"), a corporation duly organized and existing under the laws of
______________, on behalf of whom I make this affidavit.

                  2. The Owner is not transferring the Class R Certificates (the
"Residual Certificates") to impede the assessment or collection of any tax.

                  3. The Owner has no actual knowledge that the Person that is
the proposed transferee (the "Purchaser") of the Residual Certificates: (i) has
insufficient assets to pay any taxes owed by such proposed transferee as holder
of the Residual Certificates; (ii) may become insolvent or subject to a
bankruptcy proceeding for so long as the Residual Certificates remain
outstanding and (iii) is not a Permitted Transferee.

                  4. The Owner understands that the Purchaser has delivered to
the Trustee a transfer affidavit and agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit F-2. The Owner does not know or
believe that any representation contained therein is false.

                  5. At the time of transfer, the Owner has conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result
of that investigation, the Owner has determined that the Purchaser has
historically paid its debts as they became due and has found no significant
evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future. The Owner understands that the transfer of a
Residual Certificate may not be respected for United States income tax purposes
(and the Owner may continue to be liable for United States income taxes
associated therewith) unless the Owner has conducted such an investigation.

                  6. Capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Pooling and Servicing Agreement.

Group") (as amended, restated, supplemented, or modified from time to time, the
"Loan Agreement"). Capitalized terms, which are used herein but not defined
herein, shall have the meanings ascribed to them in the Loan Agreement.

     Borrower has requested that the Loan Agreement be amended to enable
Borrower to repurchase or redeem a greater principal amount of Senior

consent requested by Borrower as described in the preceding sentence.

     NOW, THEREFORE, the parties hereby agree to the following:

     1.   Section 7.8(a)(ii) of the Loan Agreement is hereby amended and
restated in its entirety as follows:

          "(ii)  any repurchase or redemption of Senior Subordinated Notes up
     to an aggregate maximum amount of $30,000,000 in any fiscal year of
     Borrower so long as (1) immediately prior to any such repurchase or
     redemption and after giving effect thereto, no Event of Default has
     occurred and is continuing; (2) prior to any such repurchase or
     redemption, Borrower's chief financial officer issues a certificate to
     Agent, in form and substance satisfactory to Agent in its Permitted
     Discretion, demonstrating that, immediately after any such repurchase or
     redemption, Borrower will have Availability of no less than the Threshold
     Excess Availability; (3) concurrently with any delivery by Borrower to the
     Trustee (as defined in the Indenture) of a notice of optional redemption
     in accordance with Section 3.01 of the Indenture in connection with any
     such redemption, Borrower delivers a copy of such notice to Agent; and (4)
     concurrently with any delivery by Borrower to the Holders (as defined in
     the Indenture) of a notice of redemption in

     redemption, Borrower delivers a copy of such notice to Agent, and"

undertaking to which it is a party or by which any of its properties may be
bound or affected; (b) consents to the transactions contemplated by this
letter agreement; (c) acknowledges and reaffirms its obligations owing to the
Lender Group under any Loan Documents to which it is a party; and (d) agrees

provision hereof:

          a.   The representations and warranties in the Loan Agreement and the
     other Loan Documents shall be true and correct in all respects on and as

     such representations and warranties relate solely to an earlier date);

          b.   No Default or Event of Default shall have occurred and be
     continuing on the date hereof or as of the date of the effectiveness of
     this letter agreement;

          c.   No injunction, writ, restraining order, or other order of any
     nature prohibiting, directly or indirectly, the consummation of the
     transactions contemplated herein shall have been issued and remain in force
